FORWARD In March 2001, the National Institutes of Health issued the following warning: "The number of Web sites offering health-related resources grows every day. Many sites provide valuable information, while others may have information that is unreliable or misleading."1 Furthermore, because of the rapid increase in Internet-based information, many hours can be wasted searching, selecting, and printing. Since only the smallest fraction of information dealing with high cholesterol is indexed in search engines, such as www.google.com or others, a non-systematic approach to Internet research can be not only time consuming, but also incomplete. This book was created for medical professionals, students, and members of the general public who want to know as much as possible about high cholesterol, using the most advanced research tools available and spending the least amount of time doing so. In addition to offering a structured and comprehensive bibliography, the pages that follow will tell you where and how to find reliable information covering virtually all topics related to high cholesterol, from the essentials to the most advanced areas of research. Public, academic, government, and peer-reviewed research studies are emphasized. Various abstracts are reproduced to give you some of the latest official information available to date on high cholesterol. Abundant guidance is given on how to obtain free-of-charge primary research results via the Internet. While this book focuses on the field of medicine, when some sources provide access to non-medical information relating to high cholesterol, these are noted in the text. E-book and electronic versions of this book are fully interactive with each of the Internet sites mentioned (clicking on a hyperlink automatically opens your browser to the site indicated). If you are using the hard copy version of this book, you can access a cited Web site by typing the provided Web address directly into your Internet browser. You may find it useful to refer to synonyms or related terms when accessing these Internet databases. NOTE: At the time of publication, the Web addresses were functional. However, some links may fail due to URL address changes, which is a common occurrence on the Internet. For readers unfamiliar with the Internet, detailed instructions are offered on how to access electronic resources. For readers unfamiliar with medical terminology, a comprehensive glossary is provided. For readers without access to Internet resources, a directory of medical libraries, that have or can locate references cited here, is given. We hope these resources will prove useful to the widest possible audience seeking information on high cholesterol. The Editors

CHAPTER 1. STUDIES ON HIGH CHOLESTEROL Overview In this chapter, we will show you how to locate peer-reviewed references and studies on high cholesterol.
The Combined Health Information Database The Combined Health Information Database summarizes studies across numerous federal agencies. To limit your investigation to research studies and high cholesterol, you will need to use the advanced search options. First, go to http://chid.nih.gov/index.html. From there, select the “Detailed Search” option (or go directly to that page with the following hyperlink: http://chid.nih.gov/detail/detail.html). The trick in extracting studies is found in the drop boxes at the bottom of the search page where “You may refine your search by.” Select the dates and language you prefer, and the format option “Journal Article.” At the top of the search form, select the number of records you would like to see (we recommend 100) and check the box to display “whole records.” We recommend that you type “high cholesterol” (or synonyms) into the “For these words:” box. Consider using the option “anywhere in record” to make your search as broad as possible. If you want to limit the search to only a particular field, such as the title of the journal, then select this option in the “Search in these fields” drop box. The following is what you can expect from this type of search: •
Overweight Associated With Chronic Health Conditions Source: Healthy Weight Journal. 16(1):3. January/February 2002. Summary: A study initially published in the Archives of Internal Medicine examined the risk for the development of chronic disease in obese and overweight men and women. Researchers analyzed the 10-year associated risks of developing high cholesterol, hypertension, gallstones, heart disease, type 2 diabetes, stroke, and colon cancer among 46,060 men in the Health Professionals Follow-up Study and 77,690 women from the Nurses Health Study. The risk of developing diabetes, hypertension, gallstones, and heart disease increased with the severity of overweight in both men and women. As weight increased, the risk of developing more than one chronic disease also increased. The authors concluded that men and women who have a Body Mass Index (BMI) between 25 and 29.9 are at an increased risk for the development of certain health

conditions. Their findings provide support for the lowering of some health organizations' measure of overweight from a BMI of 27 to 25. The researchers stressed the importance of maintaining a healthy weight. •
Part 2: Rationale for a Wellness Approach to Obesity Source: Healthy Weight Journal. 14(2):20-24. March-April 2000. Summary: Based on a review of studies comparing body mass index (BMI) and mortality, the authors conclude that extremes of weight, both overweight and underweight, result in excess mortality. The excess mortality among the underweight cannot be attributed to smoking, as is sometimes done, because the smokers who are at the highest risk for disease are not especially lean. In the elderly, leanness is an indicator for increased mortality; obesity is not a risk factor until it reaches the extremes of a BMI greater than 35. Obesity can actually be beneficial in terms of risk for some diseases. This is true for cancer, infectious diseases, chronic obstructive pulmonary disease, osteoporosis, eclampsia, peptic ulcer, and suicide, among others. In other diseases, patients were are classified as obese have a better survival rate than leaner patients. Examples are hypertension, high cholesterol, and diabetes type II. The authors caution that this does not mean that patients with these conditions should try to gain weight, but that patients who are overweight do not have as dire a prognosis as leaner patients. More dangerous in the view of the authors are the ineffective methods of weight loss attempted by many overweight patients. None have proved effective and weight cycling (repeated loss and gain of weight) has been shown to be hazardous. The authors call for a change of focus, to healthy lifestyles, rather than a focus on weight loss.

Cholesterol-Lowering Medications Source: Access. 15(1): 36-38. January 2001. Contact: Available from American Dental Hygienists' Association. 444 North Michigan Avenue, Chicago, IL 60611. Summary: Hyperlipidemia is an increased plasma (blood) lipid concentration of cholesterol, triglycerides, or both. As lipoproteins play a key role in the formation of atherosclerosis, it is important to monitor the level of dietary cholesterol to reduce the risk of heart disease. However, some people will develop high cholesterol levels simply because they are genetically predisposed to synthesize cholesterol, regardless of their good dietary practices. Treatment for high cholesterol is generally a combination of cholesterol lowering medications and nonpharmacologic methods, including eating a low fat diet, smoking cessation, and exercise. This article familiarizes dental hygienists with the medications commonly prescribed to reduce cholesterol, as well as the relevant oral care considerations. When selecting medications to reduce cholesterol, physicians must consider the drug's benefits, side effects, cost, and convenience. The author first reviews three over the counter medications available to lower cholesterol: vitamin E, psyllium, and niacin. The author then reviews drugs in categories, including the fibrates, bile acid sequestrants, probucol (Lorelco), and HMG CoA reductase inhibitors. 2 tables. 9 references.

Summary: In this article, the author provides basic information about cholesterol for people with diabetes. Topics include the differences between saturated and unsaturated fat, the causes of elevated fat and cholesterol levels in the blood, the metabolism of cholesterol, how atherosclerosis develops, where dietary fats and cholesterol come from, and how to lower high cholesterol levels. The author concludes with a review of the cholesterol-lowering medications that are currently available, including colestipol, probucol, lovastatin, pravastatin, and simvastatin, nicotinic acid, and gemfibrozil. •
Prevalence of Obesity, Diabetes, and Obesity-related Health Risk Factors, 2001 Source: Journal of the American Medical Association. 289(1):76-79. January 1, 2003. Summary: In this study, researchers estimated the prevalence of obesity and diabetes among U.S. adults in 2001 by a random-digit telephone survey of a nationally representative sample of 195,005 adults participating in the Behavioral Risk Factor Surveillance System (BRFSS). The nation's obesity rate climbed from 19.8 percent in 2000 to 20.9 percent in 2001 and the rate of diagnosed diabetes rose from 7.3 percent to 7.9 percent. The study used self- reported height and weight to calculate body mass index (BMI), with obesity defined as a BMI of 30 or higher. Overweight and obesity were significantly associated with diabetes, high cholesterol, high blood pressure, arthritis, asthma, and poor health status. The researchers conclude that increases in obesity and diabetes among U.S. adults continues to rise in both genders and all ages, races, and educational levels.

Am I Exercising Too Hard? Source: Prevention. p.74. February 2000. Summary: Individuals with cardiovascular problems should be cautious about overexertion, according to Barry Franklin, president of the American College of Sports Medicine. These problems are defined as heart disease, angina, diabetes, or risk factors for heart disease, such as smoking, obesity, high blood pressure or high cholesterol. Even those who have healthy hearts may want to check their exercise level. A method is described for finding heart rate, and a chart is included. The perceived exertion method is also described.

Production Office, 9650 Rockville Pike, Bethesda, MD 20814. (301) 530-7038. Fax (301) 571-8303. Website: www.ajcn.org. Summary: Recent research suggests that several of the major diseases of later life, including coronary heart disease, hypertension (high blood pressure), and type 2 diabetes, originate in impaired intrauterine growth and development. These diseases may be consequences of 'programming,' whereby a stimulus or insult at a critical sensitive period of early life has permanent effects on structure, physiology, and metabolism. Evidence that coronary heart disease, hypertension and diabetes are programmed came from longitudinal studies of 25,000 men and women from the United Kingdom; these studies show that size at birth was related to the occurrence of the disease in middle age. People who were small or disproportionate (thin or short) at birth had high rates of coronary heart disease, high blood pressure, high cholesterol

concentrations, and abnormal glucose-insulin metabolism. These relations were independent of the length of gestation, suggesting that cardiovascular disease is linked to fetal growth restriction rather than to premature birth. Although the influences that impair fetal development and program adult cardiovascular disease remain to be defined, there are strong pointers to the importance of the fetal adaptations invoked when the maternoplacental nutrient supply fails to match the fetal nutrient demand. 3 figures. 3 tables. 85 references. •
Part 1: Rationale for a Wellness Approach to Obesity Source: Healthy Weight Journal. 14(1):7-9,14. January-February 2000. Summary: The authors review the evidence for the view of obesity as a disease and call for a wellness approach to obesity based on a healthy lifestyle and treating disease in the obese instead of obesity as a disease. They first examine the link between obesity and type 2 diabetes, and conclude that while excess weight may indicate a risk for diabetes, the excess weight is probably not a direct cause of diabetes. This is reinforced by studies showing that six to eighteen months after treatment, patients who lost weight were at their original blood sugar levels, even when they maintained weight loss. Earnsberger and Koletsky next turn to the link between hypertension and obesity, noting that while hypertension is strongly correlated to obesity, high cholesterol is not. They cite studies which found that obese lab rats subjected to periodic fasting were more hypertensive than obese rats who did not fast. Therefore, they believe that the weight cycling may be the cause of the heart disease.

Low Cardiorespiratory Fitness and Physical Inactivity as Predictors of Mortality in Men with Type 2 Diabetes Source: Annals of Internal Medicine. 132(8): 605-611. April 18, 2000. Contact: Available from American College of Physicians. American Society of Internal Medicine. 190 North Independence Mall West, Philadelphia, PA 19106-1572. Website: www.acponline.org. Summary: This article describes a prospective cohort study that evaluated the prospective association of cardiorespiratory fitness and physical inactivity with mortality in men who have type 2 diabetes. The study population consisted of 1,263 men with type 2 diabetes who received a thorough medical examination between 1970 and 1993 and were followed for mortality up to December 31, 1994. Measurements included cardiorespiratory fitness as determined by a maximal exercise test, self reported physical inactivity at baseline, and subsequent death determined by using the National Death index. During an average followup of 12 years, 180 patients died. The prevalence of self reported physical inactivity was 50 percent in men with diabetes and 33 percent in men without diabetes. The association between low fitness and mortality was present in men with known or unknown diabetes, men who were normal weight or overweight, and men with or without a parental history of cardiovascular disease. After adjustment for age, baseline cardiovascular disease, fasting plasma glucose level, high cholesterol level, overweight, current smoking, high blood pressure, and parental history of cardiovascular disease, men in the low fitness group had an adjusted risk for all cause mortality compared with fit men. Men who reported being physically inactive had an adjusted risk for mortality that was 1.7 fold higher than that in men who reported being physically active. There was an excess number of deaths in unfit men with diabetes from the underlying causes of cardiovascular disease, cancer, diabetes, gastric disease, and injury. The article concludes that low cardiorespiratory fitness and physical inactivity

are independent predictors of all cause mortality in men with type 2 diabetes. Physicians should encourage patients who have type 2 diabetes to participate in regular physical activity and improve cardiorespiratory fitness. 1 figure. 4 tables. 43 references. (AA-M). •
Walking Compared with Vigorous Physical Activity and Risk of Type 2 Diabetes in Women: A Prospective Study Source: JAMA. Journal of American Medical Association. 282(15): 1433-1439. October 20, 1999. Summary: This article describes a study that examined the relationship of total physical activity and incidence of type 2 diabetes in women and compared the benefits of walking versus vigorous activity as predictors of subsequent risk of type 2 diabetes. Subjects for the study were 70,102 women from the Nurses' Health Study cohort who, in 1986, were free from diagnosed diabetes, cardiovascular disease, and cancer and who completed questions on physical activity in 1986. The main outcome measure was risk of type 2 diabetes by quintile of metabolic equivalent task (MET) score, based on time spent per week on each of eight common physical activities, including walking. During 8 years of follow-up, researchers documented 1,419 incident cases of type 2 diabetes. After adjusting for age, smoking, alcohol use, history of hypertension, history of high cholesterol level, and other covariates, the relative risks (RRs) of developing type 2 diabetes across quintiles of physical activity were 1.0, 0.77, 0.75, 0.62, and 0.54. After adjusting for body mass index (BMI), RRs were 1.0, 0.84, 0.87, 0.77, and 0.74. Among women who did not perform vigorous activity, multivariate RRs of type 2 diabetes across quintiles of MET score for walking were 1.0, 0.91, 0.73, 0.69, and 0.58. After adjusting for BMI, the trend remained statistically significant. Faster usual walking pace was independently associated with decreased risk. Equivalent energy expenditures from walking and vigorous activity resulted in comparable magnitudes of risk reduction. The article concludes that the data suggest that greater physical activity level is associated with substantial reduction in risk of type 2 diabetes, including physical activity of moderate intensity and duration. 1 figure. 4 tables. 44 references.

Facts on Fats Source: Diabetes Self-Management. 16(6): 89-96. November-December 1999. Contact: Available from R.A. Rapaport Publishing, Inc. 150 West 22nd Street, New York, NY 10011. (800) 234-0923. Summary: This article examines the different types of fat found in foods, the role they have in the body, and their impact on health. Fat is an important nutrient in the body because it provides energy and fatty acids necessary for good health. However, too much fat can lead to many health problems, including heart disease, some types of cancer, diabetes, and obesity. National dietary recommendations suggest that fat intake be restricted to 30 percent or less of total daily calories. Fats are a mixture of saturated, monounsaturated, and polyunsaturated fatty acids. The amounts and proportions of these types of fats in the diet affect levels of blood cholesterol in the body. Other fatty acids in food include omega-3 fatty acids and trans fatty acids. Two new products, known as Benecol and Take Control, have appeared in the margarine and butter section of the grocery store that address the issue of trans fats and blood cholesterol levels. Both can be used as other spreads would be used, but they are not recommended for use in baking. These products are intended for people who have moderate to high cholesterol levels, and they are not intended to be a substitute for cholesterol lowering drugs. The

Stroke! Source: Diabetes Forecast. 53(9): 58-62. September 2000. Contact: Available from American Diabetes Association. 1701 North Beauregard Street, Alexandria, VA 22311. (800) 232-3472. Website: www.diabetes.org. Summary: This article presents steps that people who have diabetes can take to significantly reduce their risk of stroke. Most strokes result from a blockage or rupture of a blood vessel in the brain. The blockages that cause stroke usually occur because blood clots have formed or fatty deposits have built up inside blood vessels. Strokes that occur when blood vessels burst open and bleed inside the head are less common than those caused by a blockage. Symptoms of stroke usually occur suddenly and may include weakness or numbness on one side of the body, loss of vision or dimness in one or both eyes, and difficulty talking or understanding speech. Some people experience mini strokes known as transient ischemic attacks. The symptoms for this type of stroke are the same as the symptoms of major stroke, but they last only a few minutes or hours. Although diabetes is considered a nonmodifiable risk factor for stroke, scientists are not sure why people who have diabetes are more likely to suffer a stroke. Prevention involves knowing one's individual risk factors and controlling or eliminating the modifiable ones. Modifiable risk factors include high blood pressure, high cholesterol, atrial fibrillation, cigarette smoking, heavy alcohol consumption, lack of physical activity, and obesity. The article presents suggestions for modifying these risk factors and provides a list of organizations that offer information about stroke.

What's in a Name?: Redefining Diabetes Source: Diabetes Self-Management. 15(1): 59-62. January-February 1998. Contact: Available from R.A. Rapaport Publishing, Inc. 150 West 22nd Street, New York, NY 10011. (800) 234-0923. Summary: This article provides readers with information about current American Diabetes Association (ADA) recommendations on the classification, diagnosis, and screening of diabetes. The article explains why the ADA, based on reviews by an expert committee, recommends that type 1 and type 2 diabetes no longer called 'insulindependent diabetes mellitus' (IDDM or type I) and 'non-insulin-dependent diabetes mellitus'(NIDDM or type II). The new names, type 1 and type 2, are based on cause rather than treatment, and replace Roman numerals with Arabic numerals to prevent confusion. The article explains that the term 'impaired glucose tolerance' remains unchanged, and is defined as a 2-hour oral glucose tolerance test value of 140 mg/dl or above, but less then 200 mg/dl. The term 'impaired fasting glucose' was added, and is defined by a fasting glucose level of 110 mg/dl or above, but less than 126 mg/dl. The committee recommends that gestational diabetes continue to be defined as diabetes with its first diagnosis or recognition in pregnancy. The article also explains the three ways in which diabetes is diagnosed; the committee clearly states that the fasting plasma glucose test is preferred. The committee also looked at ways to diagnose as many cases of diabetes as early as possible. Mass screening for the antibody markers of type 1 diabetes is not currently recommended. The committee recommends screening for type 2 diabetes in higher risk populations, which include anyone over age 45, and people who are obese; have a close relative with diabetes; are African American, Latino, Native

American, or Asian; have been diagnosed with gestational diabetes or delivered a baby weighing more than nine pounds; have high blood pressure; have high cholesterol; or have previously had impaired glucose tolerance or impaired fasting glucose on testing. The ADA projects that the simple fasting glucose test and increased testing of individuals at risk for developing type 2 diabetes will result in earlier detection of diabetes in many of the 5.4 million Americans currently undiagnosed. A sidebar provides information about three types of tests that can be used to determine whether a person has diabetes. (AA-M). •
Perceived Difficulty of Diabetes Treatment in Primary Care: Does It Differ by Patient Ethnicity? Source: Diabetes Educator. 27(5): 678-684. September-October, 2001. Contact: Available from American Association of Diabetes Educators. 100 West Monroe Street, 4th Floor, Chicago, IL 60603-1901. (312) 424-2426. Summary: This article reports on a cross sectional study that was undertaken to determine the attitudes of internal medicine physicians toward treating diabetes in different patient ethnic groups and compared those attitudes with those toward treating common chronic medical conditions in primary care. The survey instrument was administered to 55 internal medicine physicians. An email message was sent to each physician with a hyperlink to a site where the survey could be completed. The instrument was a modified, quantitative 10 point scale designed to measure attitudes regarding the difficulty of treating diabetes. Results showed that diabetes was perceived to be more difficult to treat than hyperlipidemia (high cholesterol or other fats) and angina (chest pain). African Americans with diabetes were perceived to be more difficult to treat than Caucasian patients. Difficulty in treating diabetes was comparable to that for hypertension (high blood pressure), arthritis, and congestive heart failure. Physicians were confident about treatment efficacy for diabetes and changing diabetes outcomes, but not about the adequacy of time and resources for diabetes treatment. The authors conclude that to improve diabetes care, there is a need to address these attitudes and concerns of internal medicine physicians. 5 tables. 30 references.

Elevated Risk of Cardiovascular Disease Prior to Clinical Diagnosis of Type 2 Diabetes Source: Diabetes Care. 25(7): 1129-1134. July 2002. Contact: Available from American Diabetes Association. 1701 North Beauregard Street, Alexandria, VA 22311. (800) 232-3472. Website: www.diabetes.org. Summary: This article reports on a study undertaken to examine whether risk of cardiovascular disease (CVD) is elevated before clinical diagnosis of type 2 diabetes in women. A total of 117,629 female nurses aged 30 to 55 years who were free of diagnosed CVD at baseline were recruited in 1976 and followed for 20 years. A total of 1,508 women had diagnosed type 2 diabetes at baseline in 1976. During 20 years of follow up, 110,227 women remained free of diabetes diagnosis and 5,894 women developed type 2 diabetes. During 2.2 million person-years of follow up, the authors documented 1,556 new cases of myocardial infarction (heart attack, MI), 1,405 strokes, 815 fatal coronary heart disease (CHD), and 300 fatal strokes. Among women who developed type 2 diabetes during follow up, the age-adjusted risk ratios of MI were 3.75 for the period before the diagnosis and 4.57 for the period after the diagnosis, compared with women who remained free of diabetes diagnosis. The risk of stroke was also significantly elevated before diagnosis of diabetes. Further adjustment for history of hypertension

High Cholesterol
(high blood pressure) or hypercholesterolemia (high cholesterol levels) did not appreciably alter the results. The authors conclude that these data indicate a substantially elevated risk of CVD before clinical diagnosis of type 2 diabetes in women. These findings suggest that aggressive management of cardiovascular risk factors is warranted in individuals at increased risk for diabetes. 2 figures. 3 tables. 15 references. •
Minimize Your Heart Risk Source: Diabetes Forecast. 54(5): 29-31. May 2001. Contact: Available from American Diabetes Association. 1701 North Beauregard Street, Alexandria, VA 22311. (800) 232-3472. Website: www.diabetes.org. Summary: This article reviews ways people who have diabetes can minimize their risk of cardiovascular disease (CVD). Modifiable risk factors for CVD include poorly controlled diabetes, hypertension, high cholesterol, obesity, physical inactivity, and smoking. Nonmodifiable risk factors include age and genetics. The first step people should take to reduce their risk of CVD is to identify whether they or members of their family have one of the major modifiable CVD risk factors. Other steps are controlling blood glucose levels, knowing body mass index and waist circumference, having blood cholesterol levels checked annually, having blood pressure checked at each doctor visit, taking one aspirin per day, and avoiding smoking. The article includes a checklist of precautions people should take before beginning an exercise program.

Suspected Kidney Disease: Putting Urinalysis Clues Into Context, Part 1 Source: Consultant. 41(13): 1749-1750, 1752-1753, 1756-1757. November, 2001. Contact: Available from Cliggott Publishing Company. 330 Boston Post Road, Darien, CT 06820-4027. (203) 661-0600. Summary: This first article in a two part series uses a case based approach to illustrate typical urinalysis results found in common renal diseases. The authors show how these results can be integrated with findings from the history, physical examination, and other laboratory studies to arrive at a reliable diagnosis and to guide treatment. Typical urinalysis (urine testing) results in patients with nephritic disease are proteinuria greater than 2 to 3 grams per 24 hours, blood detected by dipstick and microscopic examination, and red blood cell (RBC) casts in the urine. Other findings may include cryoglobulinemia (both polyclonal and monoclonal), low complement levels, and gross hematuria. Characteristic urine findings in patients with nephrotic disease are proteinuria greater than 4 grams per 24 hours, no blood or less than is seen in nephritic disease, and casts without RBCs. Nephrotic disease is also associated with edema, a low albumin level, and a high cholesterol level. An antineutrophilic cystoplasmic antibody (ANCA) assay is useful in determining the underlying cause of rapidly progressive glomerulonephritis. For example, in a patient with azotemia and cavitary lung disease, the presence of cytoplasmic ANCA suggests Wegener granulomatosis. 3 figures. 4 tables. 10 references.

Summary: This health newsletter article reviews hyperlipidemia (increased cholesterol or triglycerides in the blood) and its occurrence in transplant recipients. The author notes that organ preservation, surgical technique, postoperative care, and effective immunosuppressants are improving the life of the transplanted organ, but recipients are still succumbing to cardiovascular illness. Hyperlipidemia can occur early after the transplant procedure. Coronary artery disease (CAD), when the arteries supplying the heart become blocked with fatty substances, is the most worrisome effect of hyperlipidemia. In addition to some immunosuppressants, other medications that transplant recipients are often prescribed have been known to cause or worsen hyperlipidemia. The author stresses the importance of exercise as a way to combat high cholesterol levels in the blood. Exercise not only is beneficial on the lipid profile, but also reduces total body weight, strengthens muscle tone, and improves cardiovascular performance. Reducing saturated fat in the diet appears to have the most effect in the overall reduction of cholesterol. For patients whose hyperlipidemia is not controlled by at least three months of dietary therapy, treatment with medications should be considered. The author reviews the use of specific drugs (the 'statins') for the treatment of hypercholesterolemia and concerns about rhabdomyloysis (a breakdown of the skeletal muscle tissue, with the inability to clear the breakdown products through the kidney). The author concludes by encouraging readers to educate themselves and to work closely with their transplant team on the appropriate management of hyperlipidemia. •
Urban Living Brings Chronic Disease to Pacific Islanders Source: Obesity and Health. 7(3):51; May/June 1993. Contact: Healthy Living Institute, 402 S. 14th St., Hettinger, ND 58639. (701) 567-2645. Summary: This is a brief summary of a study conducted by Australian researchers. The researchers find that rural people, living a mostly traditional way of life, suffer much less from obesity, hypertension, diabetes, and high cholesterol than do city dwellers. Urban-dwelling Pacific Islanders are falling prey to the chronic diseases of urban living. Rural residents are leaner and report much higher levels of physical activity. They eat more total calories, but less of a percentage of fat, and more carbohydrates.

Rapaport Publishing,Inc. 150 West 22nd Street, New York, NY 10011. (800) 234-0923. Summary: This patient education article describes strokes, what they are, how they can be prevented, and how to minimize the damage a stroke can inflict. The author explains the two basic types of stroke, ischemic and hemorrhagic; the risk factors for stroke, including diabetes, high blood pressure, atrial fibrillation, high cholesterol, smoking, and alcohol use; the warning signs of stroke and the occurrence of transient ischemic attacks (TIAs), which can serve as a precursor of a true stroke; evaluation considerations, including the use of CT scans and MRI to check for signs of brain injury, poststroke; and treatment options, including surgery, drug therapy with anticoagulants, balloon angioplasty, neuroprotective drugs, and rehabilitation. By carefully attending to the risk factors, especially in people with diabetes, the chance of ever developing a stroke can be minimized. One sidebar describes surgical options used to treat carotid artery stenosis and perhaps prevent stroke. A list of additional resource organizations is also included.

Epidemiology of Macrovascular Disease in Diabetes Source: Diabetes Reviews. 5(4): 294-315. 1997. Contact: Available from American Diabetes Association. 1701 North Beauregard Street, Alexandria, VA 22311. (800) 232-3472. Website: www.diabetes.org. Summary: This review article provides information on the epidemiology of macrovascular disease in type 2 diabetes. According to the authors, evidence has accumulated from autopsy studies, clinical studies, and population-based studies to indicate that type 2 diabetes significantly increases the risk for all macrovascular complications. For example, type 2 diabetes is known to be associated with several cardiovascular risk factors such as hypertension, obesity, central obesity, hyperinsulinemia, and serum lipid and lipoprotein abnormalities. Topics include why the risk for atherosclerotic vascular disease (ASVD) is increased in type 2 diabetes; coronary heart disease; cerebrovascular disease; peripheral vascular disease; risk factors for ASVD in people with type 2; and a summary of the role of different cardiovascular risk factors as predictors for ASVD in type 2. Because the role of classic risk factors, which include high cholesterol, smoking, and elevated blood pressure, to predict ASVD is similar in people with and without type 2 diabetes, other risk factors must play a role in diabetes atherogenesis. The article points out that low HDL cholesterol and high total triglyceride levels are likely to contribute to the risk of atherosclerotic complications more in type 2 patients than in normoglycemic subjects. The authors conclude that there is considerable potential to reduce the risk for macrovascular complications in type 2 diabetes. 8 figures. 1 table. 229 references. (AA-M).

Summary: Water soluble dietary fibers decrease postprandial (after a meal) glucose (sugar) concentrations and decrease serum cholesterol concentrations. This article reports on a study examining the effects of administering psyllium to men with type 2 diabetes. Psyllium is a viscous, mostly water soluble fiber. The objective of the study was to evaluate the safety and effectiveness of psyllium husk fiber used adjunctively to a traditional diet for diabetes. After a 2 week dietary stabilization phase, 34 men with type 2 diabetes and mild to moderate hypercholesterolemia (high cholesterol) were randomly assigned to receive 5.1 grams of psyllium or cellulose placebo twice daily for 8 weeks. Serum lipid and glycemic indexes were evaluated biweekly on an outpatient basis and at weeks 0 and 8 in a metabolic ward. The psyllium group showed significant improvement in glucose and lipid values compared with the placebo group. Serum total concentrations were 8.9 percent lower and LDL (low density lipoprotein) cholesterol concentrations were 13.0 percent lower in the psyllium than in the placebo group. All day and postlunch postprandial glucose concentrations were 11 percent and 19.2 percent lower in the psyllium than in the placebo group. Both products were well tolerated, with no serious adverse events related to treatment reported in either group. The authors conclude that the addition of psyllium to a traditional diet for persons with diabetes is safe, is well tolerated, and improves glycemic and lipid control in men with type 2 diabetes and hypercholesterolemia. 1 figure. 3 tables. 45 references.

Project Title: BILE SALTS, MEMBRANES, AND CYTOTOXICITY Principal Investigator & Institution: Heuman, Douglas; Virginia Commonwealth University Richmond, Va 232980568 Timing: Fiscal Year 2001 Summary: Bile salts adsorb to membranes, at high concentrations causing membrane disruption. Adsorption of bile salts to intracellular membranes may determine many of their physiological effects, and bile salt induced membrane injury may be important in pathogenesis of cholestatic liver disease and gallstones. We have studied the adsorption of bile salts to lecithin-cholesterol vesicles and have developed and validated a quantitative model which predicts the distribution of bile salt taurine conjugates in mixed bile salt solutions between lecithin-cholesterol bilayers and the aqueous phase. In the studies proposed, this model will be generalized to a broad array of bile acids and other organic anions, membrane lipids, and solution conditions. Using large unilamellar vesicles of varying lipid composition, we will examine the relationship between membrane binding of bile salts, mixed micellar dissolution of membrane lipids (observed with quasielastic light scattering) and altered membrane permeability (release of trapped soluble markers assessed by ultrafiltration) to determine if the mixed micellar threshold concentration and the permeation threshold at which membrane leakage

begins are predictable consequences of the membrane-bound ionized bile salt/lecithin ratio. Pure protein kinase C isoenzymes (alpha, betaII, delta, epsilon) prepared in a baculovirus system will be employed to test the hypothesis that bile salts activate protein kinase C isoenzymes by binding to membranes and serving as a "bridge" between the enzymes and membrane lipids. The model of bile salt-lecithin interactions will be extended beyond the limits of the two phase (monomer-membrane) region into micellar regions of the phase diagram by combining techniques of gel filtration and ultrafiltration, in order to permit modelling of detergent effects of mixed bile salt solutions. Using synthetic vesicles, isolated canalicular plasma membranes, and living cells (erythrocytes, cultured neoplastic gallbladder epithelia) we will test the hypothesis that lecithin in bile normally protects high cholesterol plasma membranes from bile salt injury by depressing the non-lecithin- associated bile salt concentration to non-toxic levels, and that this protective effect declines predictably as the cholesterol content of biliary vesicles increases. Finally the hepatoprotective role of biliary lipids and biliary bile salt-lipid interactions will be studied in two in vivo models of bile salt-induced liver injury: acute infusion of bile salts in the choline deficient bile fistula rat and chronic feeding of bile salts in hamsters fed lithogenic diets. The ultimate goal of these studies is to provide a conceptual framework for understanding the toxic and protective properties of bile salts and the role of bile salt toxicity in human disease.

Project Title: CELLULAR MECHANISM FOR LDL RETENTION BY THE ARTERY WALL Principal Investigator & Institution: Innerarity, Thomas L.; Senior Investigator; J. David Gladstone Institutes 365 Vermont St San Francisco, Ca 94103 Timing: Fiscal Year 2001 Summary: Although it is well-documented that animals with high plasma levels of lipoproteins containing apo-B develop premature atherosclerosis, the exact mechanism is still unknown. The response-to-retention hypothesis holds that low density lipoproteins (LDL) and other atherogenic apo-B containing lipoproteins are retained or trapped in the subendothelium by interacting with intimal proteoglycans initiating early atherosclerosis. Our preliminary evidence shows that we can design and genetically alter atherogenic lipoproteins in such a way that they will not bind to artery wall proteoglycans. If the interaction with proteoglycans is a significant component in the subendothelial retention of lipoproteins, these altered lipoproteins therefore should not be retained in the subendothelium. Further, if binding to proteoglycans is the initial or a significant step in atherogenesis, then high levels of genetically altered of genetically altered defective-proteoglycan-binding LDL will be much less atherogenic than equivalent levels of normal LDL. Using transgenic mouse models we will first determine if proteoglycan-defective-binding LDL causes less atherosclerosis than normal LDL animals fed a high cholesterol diet. If mouse atherosclerosis studies indicate defective-proteoglycan-binding LDL are less atherogenic, we will investigate the mechanism with presumption that proteoglycan-binding LDL are less atherogenic, we will investigate the mechanism with the presumption that proteoglycan-defectivebinding LDL are poorly retained in the subendothelium. Using gene-targeted technology, we will generate proteoglycan-defective-binding apo-B48 to determine if the atherogenesis causes by B48-containing lipoproteins is due to their binding to proteoglycans. Finally, we will determine if lipoprotein lipase contributes to atherosclerosis in a direct bridging role by enhancing the binding of LDL with proteoglycans. These studies should help clarify how LDL and other apo-B-containing

lipoproteins cause atherosclerosis. Moreover, if the inhibition of LDL binding to proteoglycans is anti- atherogenic, then the use of small molecules to inhibit LDL binding to proteoglycans may have therapeutic potential to reduce or prevent atherosclerosis.

Principal Investigator & Institution: Brewster, Jay L.; Natural Sciences; Pepperdine University 24255 Pacific Coast Hwy Malibu, Ca 90265 Timing: Fiscal Year 2002; Project Start 01-SEP-2002; Project End 31-AUG-2005 Summary: (provided by applicant) The proper synthesis and processing of proteins is critical to normal cellular function. The endoplasmic reticulum (ER) is an organelle found in all higher organisms, whose central role in cell function is to mediate protein synthesis. Humans afflicted with abnormal protein processing in the ER and a related organelle, the Golgi body, suffer from devastating developmental abnormalities and comprise a broad category of disease known as Congenital Disorders of Glycosylation (CDGs). The key aspect of protein processing in the ER and Golgi is the addition of sugars to newly synthesized proteins, called glycosylation. This proposal seeks to characterize fundamental aspects of protein glycosylation, specifically how abnormal glycosylation influences the generation of signals within a cell. These signals are generated as a result of abnormal protein synthesis, which results in ER stress. The activation of ER stress can result in cell suicide (apoptosis), adaptation to the stress, growth arrest, or stimulation of localized inflammation. Our long-term goals focus upon how cells activate apoptosis following ER stress. This proposed project will allow characterization of the molecules that carry this stress signal, and examine how this cell suicide is executed. The improper processing of proteins in the ER and Golgi causes mutations in a variety of genes, and the type of disease that results from such mutations depends upon the identity of the mutated protein. Cystic fibrosis patients suffer lung degeneration that is the result of ER stress-activated signals as a membrane protein is improperly glycosylated, and one type of inherited hypercholesterolemia (high cholesterol) is the result of ER-associated processing deficiencies of a signal receptor. The characterization of ER stress and its signaling mechanisms will offer vital insight into the cell biology of stressed cells, and will be valuable to our understanding of diseases that result from abnormal ER function/processing.

APP
Principal Investigator & Institution: Sullivan, Patrick; Duke University Durham, Nc 27706 Timing: Fiscal Year 2001 Summary: This project proposes to test the hypothesis that apoE and cholesterol modify Abeta deposition in an isoform-dependent fashion with the apoE4 allele acting in a dominant mode. Rare mutations in amyloid precursor protein (APP) are responsible for some cases of early onset autosomal dominant Alzheimer's disease (AD). Isoform differences at the AD susceptibility gene apolipoprotein (apo) E locus affect age of onset for late on-set AD, and may influence from 15-50% of all cases. In humans, there are three major apoE isoforms designated apoE2, E3, and E4 that differ by a single amino

acid. ApoE functions to maintain cholesterol and fat homeostasis. ApoE isoforms also interact either directly or indirectly with APP to modulate the extent of Abeta deposition associated with one dimension of AD pathology. Current human studies suggest that high cholesterol increases the risk of AD. Animal studies reveal significant effects of cholesterol on APP and apoE metabolism in the brain, and on Abeta deposition, and suggest a major environmental (i.e. dietary fat and cholesterol) may modify AD pathology. We have transgenic animal models to test this hypothesis, human apoE targeted replacement mice, human apoE transgenic mice and the human APPV717F transgenic mouse. ApoE isoform-specific promoter effects on brain apoE levels will be measured under basal and high cholesterol conditions. AD-related pathology will be examined by crossing the apoE targeted replacement animals to mice bearing a human APP mutation using Abeta deposition and APP metabolism as endpoints. Finally, the ability to create animal models of the common human heterozygote, APOE3/4, will allow testing for dominant-positive or dominant-negative effects of human apoE isoforms. Modeling dietary factors that may modulate APP and apoE will advance the understanding of environmental and genetic interactions that influence the onset and progression of AD.

Project Title: CHOLESTEROL HOMEOSTASIS IN THE INBRED MOUSE Principal Investigator & Institution: Wang, David Q.; Beth Israel Deaconess Medical Center St 1005 Boston, Ma 02215 Timing: Fiscal Year 2001; Project Start 01-SEP-1999; Project End 31-AUG-2004 Summary: The intestine is an unique organ providing dietary and re-absorbed biliary cholesterol to the body. Excess cholesterol can result in cholesterol gallstone disease. Cholelithiasis is prevalent in cultures consuming a Western diet with high cholesterol, and can be induced in mouse models by a high cholesterol and cholic acid diet. Therefore, understanding cholesterol absorption is of great importance to both prevention and treatment of cholesterol gallstones. It has been known that genetic factors apparently play a critical role in the development of cholesterol gallstones in inbred mice. It has been found that differences in gallstone susceptibility between C57L and AKR strains are determined by at least two Lith (gallstone) genes, as well as that the sister of P-glycoprotein (Spgp), a canalicular bile salt transporter is a candidate gene for the Lith1. A recent observation that there is a remarkable positive correlation in eleven strains of inbred mice between percent cholesterol absorption and prevalence of cholesterol gallstones at 8 weeks of feeding the lithogenic diet strongly suggests that the extent of cholesterol absorption from the intestine may be a genetically determined step for cholesterol gallstone formation. Furthermore, it has been observed that there are gender differences in susceptibility to cholesterol gallstones, favoring males to females by 2:1. The applicant proposes five specific aims to explore genetic and physiological mechanisms of cholesterol homeostasis as well as molecular mechanisms of cholesterol absorption, and pathophysiological mechanisms of the formation of lithogenic bile and cholesterol cholelithiasis. Aim 1: To investigate genetic variations in cholesterol absorption efficiency and their role in cholesterol gallstone formation among 12 strains of inbred mice. Aim 2: To define differences in molecular mechanisms for cholesterol absorption and chylomicron formation between mice with high and low cholesterol absorption. Aim 3: To study postprandial chylomicron metabolism and its role in the lithogenesis of bile. Aim 4: Using genetically gallstone-susceptible and the SR-B1 att (knockout) mice, to elucidate the role of SR-B 1 (HDL) receptor in biliary cholesterol secretion and cholesterol gallstone formation. Aim 5: To characterize hormonal basis for

Project Title: GENE DIET EFFECTS ON ATHEROSCLEROSIS Principal Investigator & Institution: Breslow, Jan L.; Professor; Lab/Biomed Genetic/Metabolism; Rockefeller University New York, Ny 100216399 Timing: Fiscal Year 2001; Project Start 01-JUN-1984; Project End 30-JUN-2002 Summary: Atherosclerotic coronary heart disease (CHD) is the number one public health problem in the United States. CHD has been increasing in prevalence and with the aging of the baby boomers and the increase in major cardiovascular risk factors in the population (smoking, obesity and physical inactivity) over the last 10 years the problem will be even worse in the 21st century. This is not just a U.S. problem, but is occurring world wide. The WHO has recently predicted that by 2020 heart disease will replace infectious disease worldwide as the number one cause of disability expressed as years of healthy life lost to death or disease. CHD is considered a complex genetic disease with many genes involved and important gene-environment interactions. Cross cultural studies and human and animal feeding studies have clearly established a role for diet, particularly a high saturated fat, high cholesterol diet in atherosclerosis susceptibility. However, clinical studies have also established that there is great variation between people in diet responsiveness of their plasma lipoprotein pattern and presumably, although it has not been studied directly in humans, dietary effects on atherosclerosis susceptibility. Thus a better understanding of gene diet interactions as they effect lipoprotein levels and atherosclerosis susceptibility should lead to better ways to identify and treat individuals susceptible to CHD in the population. In the current competing renewal, I propose to use induced mutant mouse models to better understand the regulation of dietary cholesterol absorption and how dietary fats influence atherosclerosis susceptibility. The following specific aims are proposed: Determine the mechanism of regulation of dietary cholesterol absorption through the study of mutant mice; positional cloning of genes that regulate dietary cholesterol absorption by interbreeding mouse strains that differ in dietary cholesterol absorption; determine the effects of diets enriched in carbohydrate, saturated fat, monounsaturated fat, or polyunsaturated fat on atherosclerosis susceptibility and the mechanisms of the dietary effects observed using induced mutant mouse models of atherosclerosis.

first phase will be to develop and pilot test a methodologically sound instrument that measures perceived risk of heart disease. The second phase will be to administer this instrument to 300 White, African-American and Hispanic women at higher risk of heart disease because of smoking status, hypertension, diabetes or high cholesterol (requiring pills) and to determine the relationship of risk perception to risk reduction and other specific health behaviors. There will be 2 annual follow-ups to determine if changes in risk perception or health behavior occur. Data collected will be used as the basis of an independent grant application to expand this study to additional WHI centers and to provide information for future cardiac interventions using culturally- sensitive risk communication strategies to lessen the disease burden in African Americans and other population at high-risk for heart disease. The applicant's immediate career goals are to devote no less than 75 percent of her time to a highly structured and intensely focused research experience, over the next 4 years, to nurture development of her theoretical and practical skills in research design, implementation and analysis and in survey instrument development and test construction. This research and career development plan includes: 1) formal graduate course work in biostatistics, test construction, and decision analysis; 2) mentoring from the WHI Principal Investigator (PI) at the study site and investigators who have done pioneering work in the emerging field of risk perception in diabetes; 3) becoming thoroughly versed in the WHI operations; 4) having a formal evaluation by a Trainee Advisory Committee (TAC). The applicant will work closely under the guidance of the primary mentor (WHI PI). She will learn the rigorous methods employed in the conduct of a major, multi-center study, the WHI, will learn about the rigorous process of identifying and adjudicating coronary outcomes, and about procedures to assure research integrity.

Project Title: INTRACOCHLEAR ELECTROCHEMICAL GRADIENTS Principal Investigator & Institution: Brownell, William; Professor; Otorhinolaryn & Communica Scis; Baylor College of Medicine 1 Baylor Plaza Houston, Tx 77030 Timing: Fiscal Year 2001; Project Start 01-APR-1990; Project End 30-JUN-2003 Summary: The long-term goal of these studies is to identify the physical basis of outer hair cell electromotility. The outer hair cell enhances the sensitivity and frequency selectivity of mammalian hearing by converting the energy of hair energy. The motor is known to reside in the outer hair cell's lateral wall, a 100 nanometer thick, three-layer structure composed of two membranes with a cytoskeletal network sandwiched between them. The specific objective of this project period is to identify the contributions of the lateral wall to the modulation and maintenance of the electrochemical gradient necessary for cell function, specifically electromotility. Coordinated theoretical and experimental approaches identify how the unique molecular organization of the lateral wall influences the transport of ions, water and other molecules through the narrow space between the membranes. The contribution of cholesterol and other lipids to the lateral wall membranes wil be examined to determine how they affect electromotility and membrane permeability. The relative electromotile movement of the membranes will be measured with the goal of determining the motor location. The effect of genetically removing specific cytoskeletal proteins on electromotility will be measured. Methods include outer hair cell isolation from normal and geneticall altered animals; voltage-clamp with voltage-sensitive dyes and twopipette recording; measuring the flow of fluorescent markers with confocal microscopy; video microscopy and photometric measures of displacement; and computational modeling. Changes in outer hair cell electromotility will be ascertained in animal

models by measuring otoacoustic emissions. New medical treatments for hearing disorders associated with high cholesterol may be suggested if it is found they result from a direct action on the lateral wall. The deafness found in mice with genetically induced deficits of specific cytoskeletal proteins ha implications for the molecular basis of other forms of hereditary sensory-neural hearing loss. Clarification of the physical principles underlying electromotility will also contribute to the emerging field of biological nanotechnology.

Accumulating evidence suggests that M-CSF by influencing the recruitment, growth, survival and function of monocyte-macrophages, may contribute importantly to the promotion of atherosclerosis. Supporting this conclusion are this laboratory's recent findings showing that absence of M-CSF in apolipoprotein (apo) E or low density lipoprotein receptor-deficient mice significantly reduces atherosclerosis despite augmented hypercholesterolemia. The mechanism(s) underlying the causal role of M-CSF in atherosclerosis is not known, but may involve specific isoforms of M-CSF whose biological effects are mediated by a single receptor. The overall hypothesis is that augmented expression of tissue associated M-CSF isoforms in response to atherogenic stimuli in the vessel wall and bone marrow plays a critical role in the development of atheromatous lesions. To test aspects of this hypothesis, studies are proposed with the following specific aims: 1) to study the effects of M-CSF deficiency in the vessel wall on the development of arterial lesions by transplanting wild type. bone marrow cells into mice lacking both M-CSF and apoE and to determine by immunological assays which isoforms of M-CSF are expressed by vascular cells in the normal vessel and during atherogenesis in apo-E null mice; 2) to perform in vitro studies using cultured vascular cells from humans and osteopetrotic (op/op) mice to examine the mechanism(s) underlying the M-CSF mediated growth and activation of monocytes and intimal smooth muscle cells; 3) to produce transgenic mice expressing only the mM-CSF isoform on an op/op genetic background and to examine the effects of the mM-CSF on atherogenesis either by feeding the transgenic mice a high fat, high cholesterol diet or by crossing them with apo E-null mice to generate compound mutants expressing mMCSF on an atherogenic background. These studies may provide new and exciting information that might prove valuable in the rational design of novel therapeutic interventions for atherosclerosis.

health behaviors and socioeconomic status (SES), to influence disparities in health. Primary Aims: The investigators propose to test the independent and interrelated effects of the neighborhood social environment (e.g., neighborhood SES, social disorganization, Hispanic concentration, crime rates), neighborhood physical environment (e.g., housing conditions, availability of goods and services such as licensed alcohol distributors, fast food restaurants, grocery stores, gun shops, educational resources, recreational facilities, banking/lending institutions), and individual risk factors in predicting all-cause and cardiovascular disease (CVD) mortality in women and men. Design/methods: The investigators will conduct a prospective mortality follow-up study of 8,847 white (nonHispanic) and Hispanic women and men who participated in the Stanford Heart Disease Prevention Program (SHDPP), also referred to as the Stanford Five-City Project. This population-based CVD study included a random sample of women and men aged 25-74 who participated in one of five cross-sectional surveys (1979-1990) and were from four socioeconomically diverse California cities. The SHDPP is recognized for its comprehensive and well-standardized survey and physiologic measures that include SES (education, income, occupation), CVD risk factors (e.g., smoking, high cholesterol and saturated fat), psychosocial factors, and other health-related measures. The investigators propose to match survey data to death records for all-cause and CVD mortality endpoints, and link geocoded addresses to census data and archival data for measures of the neighborhood social and physical environment. They anticipate 824 deaths by 2000 and 1690 deaths by 2005. This work would create a new database where individuals' SES and health indicators are linked with characteristics of their specific neighborhoods. Based on their empirical findings, they will identity neighborhoods currently at high and low risk for mortality, then conduct focus groups and map neighborhood environments (e.g., social, physical, and service features) to create a geographic information system (GIS). These two activities will hopefully extend their empirical findings, generate new hypotheses, and guide the development of their Community Outreach and Education Program (COEP). Dissemination: The COEP will build on their collaborative partnerships with members of the study cities, health advocates, and health agencies that serve low SES and medically under served populations. With the involvement of these partners, they will integrate their empirical findings with knowledge from existing studies and disseminate results via the Internet, media, targeted mailings, and programs offered by the California State and local county health departments in the four study cities.

Project Title: OPOSSUM MODEL FOR THE HIGH & LOW RESPONSES TO DIET Principal Investigator & Institution: Kushwaha, Rampratap S.; Southwest Foundation for Biomedical Res San Antonio, Tx 782450549 Timing: Fiscal Year 2002; Project Start 01-MAY-2002; Project End 30-APR-2005 Summary: (provided by applicant): The goal of these proposed studies is to develop the laboratory opossum (Monodelphis domestica) as an animal model for investigating metabolic and molecular mechanisms of high and low responses to dietary lipids. Partially inbred strains of opossums exhibit individual differences in very low (VLDL) and low (LDL) density lipoprotein cholesterol concentrations in response to a high cholesterol and high fat (HCHF) diet. These differences are under strong genetic control and a major gene explains 80% of the variability. Thus, the laboratory opossum may be a unique model for investigating the metabolic and genetic basis of lipemic response to diet. An important question that is proposed to answer is whether the major gene is responsive to dietary cholesterol or dietary fat or a combination of both. Based on
Studies
21
pervious work, it is hypothesized that the difference in LDL cholesterol concentrations is due to strain differences in LDL apoB production. To test this hypothesis, LDL apoB synthesis will be conducted, cholesterol absorption and bile acid composition in high and low responding opossums on the chow and HCHF diets will be measured. Dietary cholesterol changes the expression and activity of a number of hepatic genes, and a mutation in any of these genes may affect the handling of excess dietary cholesterol by the liver. Therefore, the expression of a major hepatic and extrahepatic cholesterol responsive genes between high and low responding opossums will be measured and compared. If the activity or the expression of a major cholesterol responsive gene is associated with the lipemic responsiveness, a search for a polymorphism by singlestrand conformation polymorphism analysis will be done. If a polymorphism in the gene is also associated with the response, selectively bred animals will be genotyped and these data used for linkage analysis to determine if this is the major gene detected by genetic analysis. It is possible that this gene may also be a major determinant of dieinduced hyperlipidemia in humans. However, even if this is not the case, these studies are likely to lead to new strategies in the management of diet-induced hyperlipidemia and atherosclerosis in humans.

Project Title: PLEIOTROPIC EFFECTS ON OBESITY AND LIPOPROTEINS Principal Investigator & Institution: Blangero, John; Southwest Foundation for Biomedical Res San Antonio, Tx 782450549 Timing: Fiscal Year 2001 Summary: Obesity is an important risk factor for atherosclerosis. However, the reasons for the relationship between these disorder are still poorly understood. Evidence from body composition studies suggest that adiposity is highly correlated with several important endocrine measures including phenotypes related to glucoregulatory hormones, growth hormones, and thyroid hormones. These endocrine traits may also directly influence lipoprotein metabolism. Little is known regarding the genes that influence adiposity and their pleiotropic effects on these endocrine parameters and on correlated risk factors for atherosclerosis such as lipoprotein phenotypes. In Project 3, we will measure several adiposity-related phenotypes including total body fat (estimated using bioimpedance), serum concentrations of leptin, insulin-like growth factor I, insulin, triiodothyronine, and thyroxine in pedigreed baboons on three different dietary regimens (chow, a low cholesterol/high fat diet, and a high cholesterol/high fat diet). To better examine the underlying genetic determinants of variable gene expression, we will also measure quantitative mRNA levels of three candidate genes (the leptin structural gene, the lipoprotein lipase gene, and the glucose transporter 4 gene) in biopsied omental fat tissue. We will detect and localize loci influencing these adiposity-related phenotypes and test hypothesis regarding their pleiotropic effects on lipoprotein traits and genotype x diet interaction. Localization of quantitative trait loci will be accomplished via a genomic screen using candidate gene and STR polymorphisms in a single pedigree of 750 non-inbred baboons and in a second sample of 541 purposely inbred pedigreed baboons and their parents. Statistical linkage analyses will be performed using the multipoint variance component method which makes efficient use of all available information and which we have extended to accommodate the complications of inbred pedigrees. The resulting incorporation of inbred animals into our study design will significantly improve our power to detect quantitative trait loci influencing adiposity related phenotypes. Once a quantitative trait

locus is found, we will utilize multivariate linkage analysis to determine if adiposityrelated genes have pleiotropic effects on lipoprotein phenotypes. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: REGULATION OF AMYLOID BETA PROTEIN BY APOE & CHOLESTEROL Principal Investigator & Institution: Yankner, Bruce A.; Professor; Children's Hospital (Boston) Boston, Ma 021155737 Timing: Fiscal Year 2001; Project Start 01-JUL-2000; Project End 30-JUN-2005 Summary: (Verbatim from the Applicant's Abstract) Inheritance of the E4 allele of apolipoprotein E (apoE) is the most prevalent genetic risk factor for Alzheimer's disease (AD) and is associated with increased deposition of amyloid B protein (AB). The goal of this proposal is to elucidate the role of apoE in the metabolism of AB and amyloid precursor protein (APP) and its control by dietary cholesterol. The studies in this proposal are based on the working hypothesis that the absolute level of apoE is a major determinant of AB levels in the brain and can be regulated by dietary cholesterol. Our preliminary studies show that physiological concentrations of apoE significantly elevate the levels of the 40 and 42 amino acid forms of AB in human cortical cultures due to inhibition of AB degradation. Moreover, rats fed a high cholesterol diet show significantly elevated apoE levels in the cerebral cortex and altered processing of APP. These findings suggest that increased cortical apoE, which can be induced by a high cholesterol diet, may predispose to AB deposition and the onset of AD. The effect of apoE on the cortical metabolism of AB and APP will be investigated in apoE-knockout and apoE3 and apoE4-transgenic mice. We will determine whether apoE has the greatest effect on AB metabolism in the aging brain, and whether this effect can be modulated by dietary cholesterol. These studies will be complemented by an investigation of the effects of apoE and dietary cholesterol on plaque formation in APP-transgenic mice, and the examination of potential therapeutic approaches utilizing cholesterol-lowering drugs and neural stem cells that can scavenge apoE. The effect of a high cholesterol diet on AB production in transgenic mice that express disease-causing presenilin-1 mutations will also be examined. To elucidate the mechanism by which apoE inhibits AB degradation; the receptors and soluble factors that mediate AB clearance will be identified in primary human cortical cultures. Known candidate receptors that could mediate AB uptake, including the LDL receptor-related protein, the microglial scavenger receptor and the serpin-enzyme complex receptor, will be examined, as well as novel AB uptake receptors. These studies may help to elucidate the roles of apoE and dietary cholesterol in the pathogenesis of AD, with potentially important implications for early genotyping and therapeutic intervention.

investigate the immunopathogenic mechanisms by which C. pneumoniae infection contributes to the development of vascular disease. The proposed studies will exploit our recent findings from mouse model studies linking C. pneumoniae infection and atherosclerosis and in vitro cell culture studies on C. pneumoniae infection of arterial wall cells. The mouse models that will be used are C57BU6 and strains derived from this background strain including, apoE-deficient and TNF-A receptor and apoE double knockout mice. Atherosclerosis in C57BU6 mice can be induced by feeding with a high fat/high cholesterol diet, while apoE mice develop atherosclerosis spontaneously on a regular diet. The specific aims are to 1) further evaluate the synergistic effect of C. pneumoniae infection and hyperlipidemia on atherogenesis by infecting mice with C. pneumoniae followed by feeding animals with a high fat/high cholesterol diet and measuring the atherosclerotic lesion development using computer assisted morphometry; 2) study the effects of C. pneumoniae infection on key components in the inflammatory process of atherosclerosis that promote atherosclerotic lesion development by recruiting lymphocytes/macrophages and eliciting inflammatory responses at lesion sites. In vitro, in vivo, and ex vivo systems will be used to assay the expression of leukocyte adhesion molecules and adherence of macrophages to the endothelial surface. The effect of TNF-A on lesion development will be investigated by infecting TNF-A receptor and apoE double knockout mice and measuring lesion development using computer assisted morphometry; 3) assess the role of macrophages in the establishment of persistent C. pneumoniae infection of atheromatous lesions using cell culture to analyze vascular cell interactions and the effect on infectivity, growth and persistence of C. pneumoniae, and characterize the growth of C. pneumoniae in macrophages loaded with low density lipoproteins (foam cells). The proposed studies should prove invaluable for understanding the disease process and developing better measures for eradication or prevention of C. pneumoniae infection and for reducing atherosclerosis and coronary heart disease.

Project Title: ROLE OF PANCREATIC LIPASE IN DIETARY LIPID ABSORPTION Principal Investigator & Institution: Huggins, Kevin W.; Pathology and Lab Medicine; University of Cincinnati 2624 Clifton Ave Cincinnati, Oh 45221 Timing: Fiscal Year 2001; Project Start 01-JUN-2001 Summary: Pancreatic lipase is a 48 kD protein present in pancreatic secretions. It has been implicated to have a crucial role in the digestion of fat in the intestinal lumen. In vitro data has also suggested that pancreatic lipase activity is important for the efficient absorption of dietary cholesterol. The aims of this research proposal are to determine the relationship between pancreatic lipase gene expression and dietary fat and cholesterol absorption. This will be achieved by generating knockout mice deficient in pancreatic lipase. Initially, mice expressing various levels of pancreatic lipase will be characterized based on their growth and overall health. Fat and cholesterol absorption studies will be performed to assess the role of pancreatic lipase in dietary lipid absorption in vivo. These results will be correlated with mRNA levels to establish the relationship between PL mRNA level and fat and cholesterol absorption efficiency in the various transgenic mice. The mice will also be fed high fat and high fat/high cholesterol diets to assess the role pancreatic lipase plays in regulating serum lipid levels. The impact of recombinant adenoviral-mediated ectopic pancreatic lipase expression in the biliary epitheliurn will be performed to determine if this would be a feasible treatment for fat malabsorption associated with pancreatic insufficiency and cystic fibrosis. These studies will provide nutritionists and clinicians with mechanistic information to design effective dietary

Project Title: SYNTHESIS OF 7-DEOXYZARAGOZIC ACID A Principal Investigator & Institution: Escobar, Maya; Chemistry and Biochemistry; University of Texas Austin 101 E. 27Th/Po Box 7726 Austin, Tx 78712 Timing: Fiscal Year 2001; Project Start 01-SEP-2001 Summary: The zaragozic acids are a class of highly oxygenated natural products that have been shown to exhibit high activities in the inhibition of squalene synthase, which is an enzyme that acts in the first committed step in the biosynthetic pathway of cholesterol. Since coronary diseases are related directly to elevated serum cholesterol levels, there has been a great effort in the development of an effective treatment of high cholesterol. The zaragozic acids have been shown to have prohibitively high toxicity, however an efficient synthesis to the zaragozic acids allows for further investigation into these types of compounds as cholesterol lowering agents. The high biological activity of the zaragozic acids paired with the synthetically challenging highly oxygenated bicyclic core make 7-deoxyzaragozic acid A a an exciting target molecule.

Project Title: THE CHEMOKINE RECEPTOR CXCR-2 IN ATHEROSCLEROSIS Principal Investigator & Institution: Boisvert, William A.; Assistant Member; Scripps Research Institute Tpc7 La Jolla, Ca 92037 Timing: Fiscal Year 2001; Project Start 01-SEP-1999; Project End 31-AUG-2003 Summary: (Adapted from Investigator's Abstract): Multiple mechanisms operate to promote macrophage accumulation within the atherosclerotic intima. This proposed work stems in part from observations by others, including the finding that in apoE knockout mice which are deficient in the MCP-1 receptor CCR2, atherosclerosis is diminished, but lesion size and complexity still progress from 5-13 weeks. Also monocyte CCR2 expression in vitro is attenuated by several inflammatory mediators which can be in the plaque, or by differentiation to macrophages. They therefore propose that other mechanisms are at play in promoting macrophage retention and expansion within the atherosclerotic lesions. Base on their previous work, they have found that intimal macrophages express the chemokine receptor CXCR2, and the CXCR2 ligands, GROalpha, and IL-8. Initial data also indicate that leukocyte deficiency of the mouse CXCR2 homologue, mIL-8RH, arrested progression of early macrophagerich lesions and decreased retention of lesion macrophages. They therefore hypothesize that specific CXCR2 effects mediate the intra-lesional growth, inflammatory differentiation and activation of recruited macrophages. Their specific aims are as follows: Define the sequence of atherogenic events mediated by CXCR2, using two animal model systems. They will first transplant irradiated LDLR-/- mice with bone marrow from mIL-8/ CXCR2-/- or control mice under gnotobiotic conditions. Mice will be fed a chow or high cholesterol diet to define the role of mIL-8RH in mild vs. severe hypercholesterolemia-induced atherosclerosis. Second, to assess the role of mIL-8RH in cells other than leukocytes, they will study LDLR-/-, mIL-8RH-/- mice derived by crossbreeding. Early monocyte ingress, fatty streak formation, and lesion progression will be studied in both groups at 3 to 30 weeks. They will concurrently detect lesion mIL-8RH and macrophage markers including MOMA2 in each group of mice. They will also compare temporal and spatial macrophage accumulation, expression of mIL-8RH,

KC/GROalpha, JE/MCP-1 and CCR2, the appearance of oxLDL epitopes and lipid deposition. Test the hypothesis that CXCR2 expression acts by promoting macrophage retention in early atherosclerotic lesions, and does so in part by increasing macrophage beta1 integrin-mediated adhesion. First they will determine if retention of lesion monocytes is greater in LDLR-/-, mIL-8RH+/+ than LDLR-/-, mIL-8RH-/- mice. To do so they will isolate, label (using [3H]-glycerol) and infuse bone marrow monocytes into LDLR-/- mice on a high fat diet. Migration and retention of labeled monocytes in vivo will be measured in aortic lesions at 2,4,7, and 14 days post infusion. They will then test the hypothesis that the generalized cell culture adhesion defect of macrophages from mIL-8RH-/- mice is associated with decreased activation of beta1 integrins, which bind fibronectin (VLA-4, VLA-5). They will also study CXCR2-mediated effects on adhesion of human peripheral blood monocytes using specific neutralizing antibodies for integrins and integrin ligands. They will also test the hypothesis that macrophage CXCR2 expression is necessary for macrophage matrix invasion. Test the hypothesis that CXCR2 expression, via effects on macrophage adhesion, mediates macrophage differentiation to a distinct, pro-atherogenic inflammatory phenotype. Here they will further study human peripheral monocyte-derived macrophages and mouse wild type and mIL-8RH-/- bone marrow derived macrophages under conditions where CXCR2 is normally expressed in vitro. They will specifically look at the effects of the CXCR2 ligands, GROalpha, and IL-8 on macrophage proliferation and expression of JE/MCP-1. They will also determine if CXCCR2-mediated adhesion modulates the production of apoE, oxidation of LDL, and accumulation of cholesteryl ester. Finally based on the results of Specific Aim 2, they will test the hypothesis that VLA-5, and VLA-4 activation, via stimulation by CXCR2 ligands, regulate one or more of these activities. They will also correlate these results with the features of the mouse atherosclerotic lesions of Specific Aim 1 (i.e. in vivo correlation studies between CXCR2 expression and PCNA, oxidized LDL antigens, and scavenger receptor expression).

The National Library of Medicine: PubMed One of the quickest and most comprehensive ways to find academic studies in both English and other languages is to use PubMed, maintained by the National Library of Medicine.3 The advantage of PubMed over previously mentioned sources is that it covers a greater number of domestic and foreign references. It is also free to use. If the publisher has a Web site that offers full text of its journals, PubMed will provide links to that site, as well as to sites offering other related data. User registration, a subscription fee, or some other type of fee may be required to access the full text of articles in some journals. To generate your own bibliography of studies dealing with high cholesterol, simply go to the PubMed Web site at http://www.ncbi.nlm.nih.gov/pubmed. Type “high cholesterol” (or synonyms) into the search box, and click “Go.” The following is the type of output you can expect from PubMed for high cholesterol (hyperlinks lead to article summaries):
3 PubMed was developed by the National Center for Biotechnology Information (NCBI) at the National Library of Medicine (NLM) at the National Institutes of Health (NIH). The PubMed database was developed in conjunction with publishers of biomedical literature as a search tool for accessing literature citations and linking to full-text journal articles at Web sites of participating publishers. Publishers that participate in PubMed supply NLM with their citations electronically prior to or at the time of publication.

Except for high cholesterol, I've always been pretty healthy for my age (72). But I recently started puffing on the stairs, so my doctor sent me for a set of tests.

CHAPTER 2. NUTRITION AND HIGH CHOLESTEROL Overview In this chapter, we will show you how to find studies dedicated specifically to nutrition and high cholesterol.
Finding Nutrition Studies on High Cholesterol The National Institutes of Health’s Office of Dietary Supplements (ODS) offers a searchable bibliographic database called the IBIDS (International Bibliographic Information on Dietary Supplements; National Institutes of Health, Building 31, Room 1B29, 31 Center Drive, MSC 2086, Bethesda, Maryland 20892-2086, Tel: 301-435-2920, Fax: 301-480-1845, E-mail:
[email protected]). The IBIDS contains over 460,000 scientific citations and summaries about dietary supplements and nutrition as well as references to published international, scientific literature on dietary supplements such as vitamins, minerals, and botanicals.4 The IBIDS includes references and citations to both human and animal research studies. As a service of the ODS, access to the IBIDS database is available free of charge at the following Web address: http://ods.od.nih.gov/databases/ibids.html. After entering the search area, you have three choices: (1) IBIDS Consumer Database, (2) Full IBIDS Database, or (3) Peer Reviewed Citations Only. Now that you have selected a database, click on the “Advanced” tab. An advanced search allows you to retrieve up to 100 fully explained references in a comprehensive format. Type “high cholesterol” (or synonyms) into the search box, and click “Go.” To narrow the search, you can also select the “Title” field.
4 Adapted from http://ods.od.nih.gov. IBIDS is produced by the Office of Dietary Supplements (ODS) at the National Institutes of Health to assist the public, healthcare providers, educators, and researchers in locating credible, scientific information on dietary supplements. IBIDS was developed and will be maintained through an interagency partnership with the Food and Nutrition Information Center of the National Agricultural Library, U.S. Department of Agriculture.

CHAPTER 5. CLINICAL TRIALS AND HIGH CHOLESTEROL Overview In this chapter, we will show you how to keep informed of the latest clinical trials concerning high cholesterol.
Recent Trials on High Cholesterol The following is a list of recent trials dedicated to high cholesterol.5 Further information on a trial is available at the Web site indicated. •
Cardiovascular Evaluation of Patients with High Cholesterol and Normal Volunteers Condition(s): Atherosclerosis; Hypercholesterolemia Study Status: This study is currently recruiting patients. Sponsor(s): National Heart, Lung, and Blood Institute (NHLBI) Purpose - Excerpt: Homozygous familial hypercholesterolemia is a rare inherited disease of metabolism. It occurs in less than 1 in 1 million people within the United States. Patients with the disease are typically children and young adults who develop heart disease early in life. Children less than age 5 years with this disease have suffered heart attacks and death. The normal process that removes cholesterol particles from the blood stream does not work in patients with this disease. It causes cholesterol to buildup in the arteries and leads to hardening of the arteries (atherosclerosis). The goal of this study is to detect and measure atherosclerosis in these patients before it becomes permanent and potentially life threatening. Patients with this disease can participate in this study. Researchers plan to evaluate patients with homozygous familial hypercholesterolemia using new and standard methods for detecting atherosclerosis. Researchers plan to use information gathered during this study to develop new, promising treatments such as liver transplantation and gene therapy.

Safety and Effectiveness of Flaxseed for Reducing High Cholesterol Condition(s): Hypercholesterolemia Study Status: This study is currently recruiting patients. Sponsor(s): National Center for Complementary and Alternative Medicine (NCCAM) Purpose - Excerpt: Flaxseed, a rich source of fiber, may be a significant component of a cholesterol-reducing diet. The purpose of this study is to evaluate the safety and effectiveness of flaxseed in reducing high cholesterol. Phase(s): Phase II; Phase III Study Type: Interventional Contact(s): see Web site below Web Site: http://clinicaltrials.gov/ct/show/NCT00051415
Keeping Current on Clinical Trials The U.S. National Institutes of Health, through the National Library of Medicine, has developed ClinicalTrials.gov to provide current information about clinical research across the broadest number of diseases and conditions. The site was launched in February 2000 and currently contains approximately 5,700 clinical studies in over 59,000 locations worldwide, with most studies being conducted in the United States. ClinicalTrials.gov receives about 2 million hits per month and hosts approximately 5,400 visitors daily. To access this database, simply go to the Web site at http://www.clinicaltrials.gov/ and search by “high cholesterol” (or synonyms). While ClinicalTrials.gov is the most comprehensive listing of NIH-supported clinical trials available, not all trials are in the database. The database is updated regularly, so clinical trials are continually being added. The following is a list of specialty databases affiliated with the National Institutes of Health that offer additional information on trials: •

CHAPTER 6. PATENTS ON HIGH CHOLESTEROL Overview Patents can be physical innovations (e.g. chemicals, pharmaceuticals, medical equipment) or processes (e.g. treatments or diagnostic procedures). The United States Patent and Trademark Office defines a patent as a grant of a property right to the inventor, issued by the Patent and Trademark Office.6 Patents, therefore, are intellectual property. For the United States, the term of a new patent is 20 years from the date when the patent application was filed. If the inventor wishes to receive economic benefits, it is likely that the invention will become commercially available within 20 years of the initial filing. It is important to understand, therefore, that an inventor’s patent does not indicate that a product or service is or will be commercially available. The patent implies only that the inventor has “the right to exclude others from making, using, offering for sale, or selling” the invention in the United States. While this relates to U.S. patents, similar rules govern foreign patents. In this chapter, we show you how to locate information on patents and their inventors. If you find a patent that is particularly interesting to you, contact the inventor or the assignee for further information. IMPORTANT NOTE: When following the search strategy described below, you may discover non-medical patents that use the generic term “high cholesterol” (or a synonym) in their titles. To accurately reflect the results that you might find while conducting research on high cholesterol, we have not necessarily excluded nonmedical patents in this bibliography.
Patents on High Cholesterol By performing a patent search focusing on high cholesterol, you can obtain information such as the title of the invention, the names of the inventor(s), the assignee(s) or the company that owns or controls the patent, a short abstract that summarizes the patent, and a few excerpts from the description of the patent. The abstract of a patent tends to be more technical in nature, while the description is often written for the public.

Method for measuring human cholesterol absorption using metabolically stable isotopes Inventor(s): Bosner; Matthew S. (14330 Wainridge, Chesterfield, MO 63110), Lange, III; Louis G. (390 Escobar Rd., Portola Valley, CA 94028), Ostlund; Richard E. (39 Fair Oaks, Ladue, MO 63124) Assignee(s): none reported Patent Number: 5,432,058 Date filed: September 30, 1992 Abstract: This invention is a method for measuring the ability of a human to absorb cholesterol. The method uses two different cholesterol tracers, the first injected into the blood stream and the second ingested by the human subject. After a waiting period a blood sample is taken from the human subject and analyzed to determine percent cholesterol absorption based on the actual amounts of the two naturally occurring,
Patents 63
metabolically stable cholesterol tracers in the blood. The method of this invention is useful in identifying human subjects as high cholesterol absorbers and thereafter administering therapeutic agents to the subject that inhibit the absorption of cholesterol. Excerpt(s): This invention concerns a method for measuring the ability of a human to absorb cholesterol and the use of the method to treat high cholesterol absorbers. The method uses unique injected and ingested naturally occurring, metabolically stable cholesterol tracers and measures the relative amounts of both of the cholesterol tracers in the blood of a human subject after a waiting period. Dietary cholesterol restriction is an important part of therapy for many forms of hyperlipidemia as well as a general recommendation for the public. However, the relation between atherosclerosis and the diet needs further, investigation. Previous studies of dietary cholesterol absorption have focused on middle-aged men, often with hyperlipidemia or atherosclerosis, and have used radioactive methods. These data may not be applicable to other populations. In addition, the use of radioactivity generally precludes the study of women and children making a thorough analysis of the clinical genetics of cholesterol absorption impossible. The method of this invention is ideal for determining cholesterol absorption because it uses only plasma cholesterol measurements and avoids both the inconvenience and increased analytical variability associated with stool collection. Such a method was proposed by Zilversmit, but was based upon cholesterol labeled with tritium (administered intravenously) and carbon-14 (given orally). Isotopic ratio determination in plasma after 3 days of equilibration in the rapidly-miscible pool of body cholesterol provides an estimation of fractional absorption. During this time period, a negligible amount of cholesterol tracer is PG,3 excreted from the body. Such an isotope ratio method has been validated in man by comparison to other methods including those that involve oral administration of radiolabeled cholesterol and stool collection.

Oil and fat composition containing phytosterol Inventor(s): Goto; Naohiro (Ibaraki, JP), Nishide; Tsutomu (Ibaraki, JP), Tanaka; Yukitaka (Ibaraki, JP), Yasukawa; Takuji (Ibaraki, JP) Assignee(s): Kao Corporation (Tokyo, JP) Patent Number: 6,025,348 Date filed: April 30, 1998 Abstract: An oil/fat composition is provided which lowers the blood cholesterol level of a person having a high cholesterol level when used in daily life similarly to ordinary fats and is usable without posing any problem concerning appearance, flavor, heat cooking, etc. as compared with generally edible fats, wherein the oil/fat composition contains a phytosterol contained in an oil/fat containing one or more polyhydric alcohol/fatty acid esters each having a degree of esterification of 2 or higher and containing at least one hydroxyl group remaining unesterified. Excerpt(s): The present invention relates to an oil and fat composition which, when used in daily life similarly to ordinary fats, can lower the blood cholesterol level of a person having a high cholesterol level. It further relates to a food and a pharmaceutical preparation each containing the oil and fat composition. There are many drugs and food materials which lower the blood cholesterol level and are highly effective in prophylaxis and therapy. However, since these substances are used in the form of a medicine or auxiliary nutrient food, they should be ingested while paying attention to control of the
64
High Cholesterol
blood cholesterol level of the subject ingesting them. Among the components effective in lowering blood cholesterol are phytosterols. Phytosterols are contained in plant seeds in large amounts and are contained in ordinary edible vegetable oils in amounts of about 0.1 to 1.0% by weight. Many investigations have been made on the blood cholesterol lowering effect of phytosterols. It has been reported that the daily phytosterol ingestion necessary for significantly lowering the blood cholesterol level is 236 mg to 18 g per day (e.g., Ann. Nutr. Metab., 39, 291, 1995).

Genes and polymorphisms associated with cardiovascular disease and their use Inventor(s): Bansal, Aruna; (Landbeach, GB), Braun, Andreas; (San Diego, CA), Kleyn, Patrick W.; (Concord, MA) Correspondence: Heller Ehrman White & Mcauliffe Llp; 4250 Executive SQ; 7th Floor; LA Jolla; CA; 92037; US Patent Application Number: 20030036057 Date filed: March 9, 2001 Abstract: Genes and polymorphisms associated with cardiovascular disease, methods that use the polymorphism to detect a predisposition to developing high cholesterol, low HDL or cardiovascular disease, to profile the response of subjects to therapeutic drugs and to develop therapeutic drugs are provided. Excerpt(s): The field of the invention involves genes and polymorphisms of these genes that are associated with development of cardiovascular disease. Methods that use polymorphic markers for prognosticating, profiling drug response and drug discovery are provided. Diseases in all organisms have a genetic component, whether inherited or resulting from the body's response to environmental stresses, such as viruses and toxins. The ultimate goal of ongoing genomic research is to use this information to develop new ways to identify, treat and potentially cure these diseases. The first step has been to

Patents 67
screen disease tissue and identify genomic changes at the level of individual samples. The identification of these "disease" markers has then fueled the development and commercialization of diagnostic tests that detect these errant genes or polymorphisms. With the increasing numbers of genetic markers, including single nucleotide polymorphisms (SNPs), microsatellites, tandem repeats, newly mapped introns and exons, the challenge to the medical and pharmaceutical communities is to identify genotypes which not only identify the disease but also follow the progression of the disease and are predictive of an organism's response to treatment. Polymorphisms have been known since 1901 with the identification of blood types. In the 1950's they were identified on the level of proteins using large population genetic studies. In the 1980's and 1990's many of the known protein polymorphisms were correlated with genetic loci on genomic DNA. For example, the gene dose of the apolipoprotein E type 4 allele was correlated with the risk of Alzheimer's disease in late onset families (see, e.g., Corder et al. (1993) Science 261: 921-923; mutation in blood coagulation factor V was associated with resistance to activated protein C (see, e.g., Bertina et al. (1994) Nature 369:64-67); resistance to HIV-1 infection has been shown in Caucasian individuals bearing mutant alleles of the CCR-5 chemokine receptor gene (see, e.g., Samson et al. (1996) Nature 382:722-725); and a hypermutable tract in antigen presenting cells (APC, such as macrophages), has been identified in familial colorectal cancer in individuals of Ashkenzi jewish background (see, e.g., Laken et al. (1997) Nature Genet. 17:79-83). There may be more than three million polymorphic sites in the human genome. Many have been identified, but not yet characterized or mapped or associated with a disease. Polymorphisms of the genome can lead to altered gene function, protein function or mRNA instability. To identify those polymorphisms that have clinical relevance is the goal of a world-wide scientific effort. Discovery of such polymorphisms will have a fundamental impact on the identification and development of diagnostics and drug discovery.

METHODS FOR DECREASING BETA AMYLOID PROTEIN Inventor(s): NADEAU, PHILIP; (BOSTON, MA), YANKNER, BRUCE A.; (WEST NEWTON, MA) Correspondence: Patrea L Pabst; Holland & Knight Llp; One Atlantic Center Suite 2000; 1201 W Peachtree Street; Atlanta; GA; 30309-3400; US Patent Application Number: 20020081263 Date filed: January 28, 1999 Abstract: Blood cholesterol levels are correlated with production of amyloid.beta. protein (A.beta.), and are predictors of populations at risk of developing AD. Methods for lowering blood cholesterol levels can be used to decrease production of A.beta., thereby decreasing the risk of developing AD. The same methods and compositions can also be used for treating individuals diagnosed with AD. Methods include administration of compounds which increase uptake of cholesterol by the liver, such as the administration of HMG CoA reductase inhibitors, administration of compounds which block endogenous cholesterol production, such as administration of HMG CoA reductase inhibitors, administration of compositions which prevent uptake of dietary cholesterol, and administration of combinations of any of these which are effective to lower blood cholesterol levels. Methods have also been developed to predict populations at risk, based on the role of cholesterol in production of A.beta. For example, individuals with Apo E4 and high cholesterol, defined as a blood cholesterol level of greater than 200 mg/dl, post menopausal women with high cholesterol levels-especially those who are not taking estrogen, or individuals which high blood cholesterol levels who are not obese are all at risk of developing AD if blood cholesterol levels are not decreased. Excerpt(s): Alzheimer's disease (AD) is the most common cause of dementia in the aged population. The accumulation of large numbers of senile plaques containing the 40-42 amino acid amyloid.beta. protein (A.beta.) is a classic pathological feature of AD. Both genetic and cell biological findings suggest that the accumulation of A.beta. in the brain is the likely cause of AD (Yankner, B. A. (1996) Neuron 16, 921-932.; Selkoe, D. J. Science 275, 630-631 (1997)). Strong genetic evidence in support of the pathogenic role of A.beta. came from the observation that individuals who inherit mutations in the amyloid precursor protein almost invariably develop AD at an early age. These mutations increase the production of a long variant of the A.beta. peptide that forms senile plaques in the brain (Goate et al., (1991) Nature 349, 704-706). Mutations and allelic variations in other genes that cause AD, including the presenilins and apolipoprotein E, also result in increased production or deposition of the A.beta. peptide. Reiman, et al. (1996) N. E. J. Med. 334, 752-758, reported that in middle age, early to mid 50's, individuals who are homozygous for the Apo E4 gene have reduced glucose metabolism in the same regions
Patents 69
of the brain as in patients with Alzheimer's disease. These findings suggest that the pathological changes in the brain associated with this gene start early. Furthermore, individuals with Down's syndrome overexpress the amyloid precursor protein, develop A.beta. deposits in the brain at an early age, and develop Alzheimer's disease at an early age. Finally, the A.beta. protein has been demonstrated to be highly toxic to nerve cells. Thus it is widely believed that drugs which decrease the levels of A.beta. in the brain would prevent Alzheimer's disease. The known genetic causes of AD can account for only a small proportion of the total number of cases of AD. Most cases of AD are sporadic and occur in the aged population. A major goal of research is the identification of environmental factors that predispose to AD that would be amenable to therapeutic measures. It is therefore an object of the present invention to provide methods for predicting populations at risk of developing AD. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •
Substance for lowering high cholesterol level in serum and methods for preparing and using the same Inventor(s): Miettenen, Tatu; (Espoo, FI), Vanhanen, Hannu; (Helsinki, FI), Wester, Ingmar; (Raisio, FI) Correspondence: Arent Fox Kintner Plotkin & Kahn; 1050 Connecticut Avenue, N.W.; Suite 400; Washington; DC; 20036; US Patent Application Number: 20030134833 Date filed: November 7, 2002 Abstract: The invention relates to a substance which lowers LDL cholesterol levels in serum and which is fat soluble.beta.-sitostanol fatty acid ester, and to a method for preparing and using the same. The substance can be taken orally as a food additive, food substitute or supplement. A daily consumption of the.beta.-sitostanol ester in an amount between about 0.2 and about 20 g/day has been shown to reduce the absorption of biliary and endogenic cholesterol. Excerpt(s): This application is a continuation-in-part of U.S. Ser. No. 08/508,623, filed Jul. 28, 1995, which is a continuation-in-part of U.S. Ser. No. 08/140,085, filed Nov. 22, 1993, now U.S. Pat. No. 5,502,045, which claims priority on WO92/19640, filed Nov. 12, 1992, which claims priority on Finnish Patent application No. PCT/F191/00139 filed May 3, 1991. A high cholesterol level in serum can be lowered effectively by altering the intestinal metabolism of lipids. In this case the aim may be to hamper the absorption of triglycerides, cholesterol or bile acids. It has been observed in a number of investigations that certain plant sterols, such as.beta.-sitosterol (24-ethyl-5.alpha.-cholestane-3.beta.-ol) and its hardened form,.beta.-sitostanol (24-ethyl-5.alpha.-cholestane- -3.beta.-ol), lower serum cholesterol levels by reducing the absorption of dietary cholesterol from the intestines (1-25). The use of plant sterols can be considered safe, since plant sterols are natural components of vegetable fats and oils. Plant sterols themselves are not absorbed from the intestines, or they are absorbed in very low concentrations. A decreased incidence of coronary disease is clearly associated with a decrease in serum cholesterol, in particular LDL cholesterol. A high serum cholesterol value is the most significant single indicator of the risk of coronary disease. The degree of cholesterol absorption depends on a hereditary property, apoprotein E-phenotype. Apoprotein E is a protein which belongs to serum lipoproteins and takes part in the transport of cholesterol in the system (26). Of alleles associated with the synthesis of apoprotein E, i.e. the lipoprotein which affects absorption, there are known three types, e2, e3, and e4,
70

which combine in pairs at random. Alleles are capable of forming in total six different combinations. The higher the sum of the subindices, the better absorbable the cholesterol and the higher the level of cholesterol, in particular bad LDL cholesterol, in the serum (27). e4 allele is over represented among the hereditary factors of Finns, so that its proportion is almost double as compared with many European populations (28).

Summary: A healthy mouth is part of a healthy lifestyle and recent evidence suggests that poor oral health may be as detrimental to general health as other risk factors, such as smoking or high cholesterol levels. Although the beneficial systemic effects of oral therapy have not been demonstrated, the oral benefits clearly have a positive impact on the quality of life. This chapter on the systemic effects of periodontal diseases is from a periodontics textbook that focuses on diagnosis and clinical management. The authors discuss which systemic diseases are linked with periodontal disease, who is most at risk, how oral infection can affect overall health, the entry of periodontal pathogens into the bloodstream, systemic inflammation caused by periodontal pathogens, the evidence linking periodontal disease to heart disease, periodontal infection during pregnancy, the relationship among periodontitis, pneumonia and osteoporosis, the risks associated with periodontal disease in people with diabetes, animal models, and the potential impact on dentistry. The authors note that the recognition of the medical necessity for periodontal care will increase the perceived importance of dental services, and the demand for dental services will increase. 88 references.

In addition to LOCATORPlus, in collaboration with authors and publishers, the National Center for Biotechnology Information (NCBI) is currently adapting biomedical books for the Web. The books may be accessed in two ways: (1) by searching directly using any search term or phrase (in the same way as the bibliographic database PubMed), or (2) by following the links to PubMed abstracts. Each PubMed abstract has a "Books" button that displays a facsimile of the abstract in which some phrases are hypertext links. These phrases are also found in the books available at NCBI. Click on hyperlinked results in the list of books in which the phrase is found. Currently, the majority of the links are between the books and PubMed. In the future, more links will be created between the books and other types of information, such as gene and protein sequences and macromolecular structures.

Summary: This chapter answers questions about the meditations used to treat diabetes complications, including nonprescription analgesics, tricyclic antidepressants, capsaicin cream, angiotensin converting enzyme (ACE) inhibitors, laxatives, and calcium channel blockers. Nonprescription analgesics, antidepressants, and narcotic analgesics can be used to treat the pain associated with diabetic neuropathy. Capsaicin cream, a chemical found in hot chili peppers, can be applied to the feet to relieve pain. ACE inhibitors can be used to treat microalbuminuria, an early sign of kidney damage. The symptoms of gastroparesis, a condition that affects the nerves of the stomach, can be treated with metoclopramide, cisapride, and erythromycin. These medications increase the stomach's ability to contract and aid in digestion. Constipation can be treated by increasing the amount of fluid and fiber in a person's diet. Laxatives may also be useful in treating constipation. Men who have diabetes and experience impotence can use the medications alprostadil and sildenafil to maintain an erection. People who have diabetes and high blood pressure can be treated with ACE inhibitors, diuretics, and calcium channel blockers. Angiotensin receptor II antagonists and calcium channel blockers can be used to treat kidney disease. People who have diabetes should take any medications their doctor prescribes for other conditions, such as high blood pressure, heart disease, high cholesterol or triglycerides, obesity, and insulin resistance.

PRICE: $19.95 for members; plus shipping and handling. ISBN: 1570400091. Summary: This chapter deals with solving circulation problems in people who have diabetes. High levels of sugar in the blood makes the blood thick and sticky, so it cannot flow well. Therefore, chronically high levels of blood glucose can increase the risk of cardiovascular disease and other complications of diabetes. Coronary artery disease can develop in a person whose heart does not get the blood it needs. Angina is a form of coronary artery disease in which a person experiences chest pain. Although the condition is not life-threatening, it does indicate a reduced flow of blood to the heart and should not be ignored. A heart attack occurs when the flow of blood to the heart is interrupted abruptly. The chapter presents information on the symptoms, diagnosis, and pharmacological and surgical treatment of angina and discusses the symptoms, treatment, and prevention of a heart attack. Another cardiovascular problem people who have diabetes may experience is congestive heart failure. This condition results when the heart cannot pump out enough blood to get to the parts of the body that need it. The chapter discusses this condition in terms of recognizing, handling, treating, and preventing it. Cholesterol abnormalities may also increase the risk of developing coronary artery disease. Risk factors that contribute to high cholesterol levels include heredity, age, gender, diet, weight, physical activity level, and alcohol consumption. The chapter explains how a person can determine whether his or her cholesterol level is too high and discusses the use of diet, exercise, weight loss, cholesterol-lowering medication, and hormone replacement therapy to treat high cholesterol. In addition, the chapter provides the reader with information on risk factors, symptoms, treatment, and prevention of stroke, hypertension, and peripheral vascular disease.

PRICE: $14.95 plus shipping and handling. ISBN: 1580400612. Summary: This chapter provides information on diabetic nephropathy. In this complication of diabetes, the blood vessels that carry blood and toxins to the kidneys become blocked and leaky, causing some toxins to remain in the blood. Factors that contribute to the risk of developing diabetic nephropathy include time since developing diabetes, poor blood glucose control, genetic factors, high blood pressure, smoking, and high cholesterol levels. The chapter explains how diabetic nephropathy develops in people who have type 1 and type 2 diabetes and discusses the prevention and treatment of this complication. Controlling both blood glucose levels and blood pressure levels can help prevent kidney damage. The development of diabetic nephropathy can be slowed with the use of a group of blood pressure medications called angiotensin converting enzyme (ACE) inhibitors, even when blood pressure is normal. ACE inhibitors appear to lower microalbuminuria and keep the kidneys working. Common side effects of ACE inhibitors are a cough and an increase in potassium level in the blood. Other steps people can take to prevent or slow the progression of kidney disease include treating urinary tract infections quickly, avoiding drugs that could harm kidney function such as ibuprofen and naproxen, undergoing diagnostic tests that do not require the use of contrast agents, and treating a neurogenic bladder. Adults with type 2 diabetes and young people past puberty who have had diabetes for 5 years should be screened for nephropathy on a yearly basis. The chapter includes a list of questions a patient may ask a doctor and questions a doctor may ask a patient. 1 figure. 1 table.

PRICE: $12.95 for members; $14.95 for nonmembers; plus shipping and handling. ISBN: 1580400353. Summary: This chapter provides people who have diabetes with information on blood fats. People with diabetes often have high blood fat levels. This increases their risk for cardiovascular problems. Fats in the body include cholesterol and triglycerides. They are carried by lipoproteins, including very low density lipoproteins, low density lipoproteins, and high density lipoproteins. The chapter presents the healthiest blood fat levels and suggests ways to improve blood fat levels if they exceed healthy levels. Tips include controlling one's diabetes, losing weight, cutting back on all fats, replacing saturated fats with unsaturated fats, eating fewer high cholesterol foods and more high fiber foods, exercising, and quitting smoking.

Summary: This videotape, part of a series on living with diabetes, focuses on the diagnosis of diabetes. A moderator discusses the new criteria for the diagnosis and classification of diabetes, the rise in the incidence of diabetes, the symptoms of diabetes, and the prevention of diabetes with an endocrinologist. The videotape begins with a discussion of what diabetes is, how insulin works, the types of diabetes, and risk factors for diabetes. Type 1 diabetes, which was formerly known as insulin dependent diabetes, usually develops quickly, whereas type 2 diabetes, which was formerly known as
80
High Cholesterol
noninsulin dependent diabetes, usually has a gradual onset. The symptoms of diabetes, which are generally the same regardless of the type, are related to high blood sugar. They include excessive urination and thirst, fatigue, hunger, weight loss, and blurred vision. Risk factors for type 1 diabetes include a genetic predisposition for developing the disease. Risk factors for type 2 diabetes include being overweight, sedentary, and over 45 years old; having a history of stillbirth or gestational diabetes; having high blood pressure and high cholesterol; being African American, Hispanic, or Native American; and having previously been identified with impaired glucose tolerance. The acute complications of diabetes include ketoacidosis, nonketotic hyperosmolar syndrome, and hypoglycemia. The chronic complications are divided into microvascular and macrovascular complications. Microvascular complications include retinopathy, neuropathy, and nephropathy. Macrovascular complications include heart attack, stroke, and peripheral vascular disease. Early diagnosis is important in preventing complications. Diagnosis is based on blood sugar levels obtained from a blood glucose test, a fasting plasma glucose test, or an oral glucose tolerance test. The risk of developing type 2 diabetes may be reduced by eating properly, maintaining an ideal weight, and exercising. The videotape includes a self test that viewers can take to assess their risk of developing type 2 diabetes.

(701) 567-2645. Summary: Ernsberger says that since weight loss is so difficult and the effects transitory, obese individuals should instead strive for a healthier lifestyle. By reducing the intake of saturated fats, exercising more, and consuming more fruits and vegetables, individuals may not lose as much weight, according to Ernsberger. However, he says, they will have lower cholesterol and blood sugar levels, as well as lower blood pressure. According to Ernsberger, since this is so, physicians should focus on a lower-fat diet, exercise and medication as treatments for high blood pressure, diabetes and high cholesterol. He says improvements in these conditions brought about by weight loss are temporary, and that weight loss attempts can actually be harmful by preventing the patient from pursuing other treatments.

Beyond the ABCs of Nutrition Source: Prevention Report. p.1-2,11. December 1992/January 1993. Summary: This newsletter article discusses the introduction of a nutrition education curriculum into the elementary school classroom. Early evidence shows that these new approaches are beginning to have an impact, and that the children of the 1990s will have a solid nutrition knowledge base. However, an alarming number of children, ages 3 through 17, are overweight, have high cholesterol, and high blood pressure. The article discusses studies that are examining the incidence and prevalence of obesity in children, including the National Heart, Lung, and Blood Institute (NHLBI) Growth and Health Study. Expanding nutrition education in the schools is a Healthy People 2000 objective. Nutrition education received a boost with the release of the Food Guide Pyramid; food industry and commodity groups have adopted the Pyramid to help explain good nutrition to children. The article briefly reviews other measures being implemented to enhance nutrition and nutrition education of young children.

Can Celiacs Eat Cheese?: A Resounding Yes! If the Cheese is Real, Maybe Not if It's 'Processed' Source: Gluten-Free Living. 5(6): 1, 13. November-December 2000. Contact: Available from Gluten-Free Living. P.O. Box 105, Hastings-On-Hudson, NY 10706. (914) 969-2018. E-mail:
[email protected]. Website: www.celiac.com. Summary: This newsletter article for people following a gluten free diet (to treat celiac disease or dermatitis herpetiformis, for example) explains how to incorporate cheese into one's diet. The author stresses that, with the exception of French Roquefort, 'real' cheese is a top quality food that people with celiac disease can enjoy to the fullest, though perhaps not if they are overweight, severely lactose intolerant, or have high cholesterol. The author briefly reviews the categories of cheese (fresh, soft fermented, and hard fermented), emphasizing the benefits of buying quality cheeses. The author explains why Roquefort may be off limits; it is made from sheep's milk and aged with mold spores that form on specially baked loaves of rye bread. The cheese therefore

contains gliadins, albeit in tiny amounts and perhaps rendered harmless by the mold spores themselves. The article concludes with a discussion of 'processed' cheese, which is usually made from a combination of natural cheese, vegetable based gums, dyes, emulsifiers, and stabilizers, any of which may contain gluten. One sidebar offers a recipe for goat cheese dip, the availability of a kit to make mozzarella, and summaries of two books about cheese. •
Gout: How To Control an Ancient Disease Source: Mayo Clinic Women's HealthSource. 4(6): 6. June 2000. Contact: Available from Mayo Clinic Women's HealthSource, 200 First Street SW, Rochester, MN 55905. (800) 876-8633 or (303) 604-1465. Email:
[email protected]. Summary: This newsletter article provides people who have gout with information on controlling this disease. Gout, or gouty arthritis, has been recognized for more than 2,000 years. It is caused by too much uric acid. People who have gout either produce too much uric acid or excrete too little. Uric acid is typically dissolved in the blood and passed through the kidneys into the urine. When excess uric acid builds up, sharp crystals can form and deposit in a joint and surrounding tissue. This causes pain, inflammation, and swelling. Other factors that contribute to gout include foods high in purines, alcohol consumption, obesity, high cholesterol, diabetes, and medications. Diagnosis involves undergoing a blood uric acid test and having fluid drawn from the affected joint to look for crystals. An acute attack can be treated with nonsteroidal antiinflammatory drugs. Preventive treatment involves a regimen of medications such as allopurinol. Lifestyle changes such as weight loss, dietary changes, and abstinence from alcohol can also help. 1 figure.

CHAPTER 10. RESEARCHING MEDICATIONS Overview While a number of hard copy or CD-ROM resources are available for researching medications, a more flexible method is to use Internet-based databases. Broadly speaking, there are two sources of information on approved medications: public sources and private sources. We will emphasize free-to-use public sources.
U.S. Pharmacopeia Because of historical investments by various organizations and the emergence of the Internet, it has become rather simple to learn about the medications recommended for high cholesterol. One such source is the United States Pharmacopeia. In 1820, eleven physicians met in Washington, D.C. to establish the first compendium of standard drugs for the United States. They called this compendium the U.S. Pharmacopeia (USP). Today, the USP is a nonprofit organization consisting of 800 volunteer scientists, eleven elected officials, and 400 representatives of state associations and colleges of medicine and pharmacy. The USP is located in Rockville, Maryland, and its home page is located at http://www.usp.org/. The USP currently provides standards for over 3,700 medications. The resulting USP DI® Advice for the Patient® can be accessed through the National Library of Medicine of the National Institutes of Health. The database is partially derived from lists of federally approved medications in the Food and Drug Administration’s (FDA) Drug Approvals database, located at http://www.fda.gov/cder/da/da.htm. While the FDA database is rather large and difficult to navigate, the Phamacopeia is both user-friendly and free to use. It covers more than 9,000 prescription and over-the-counter medications. To access this database, simply type the following hyperlink into your Web browser: http://www.nlm.nih.gov/medlineplus/druginformation.html. To view examples of a given medication (brand names, category, description, preparation, proper use, precautions, side effects, etc.), simply follow the hyperlinks indicated within the United States Pharmacopeia (USP). Below, we have compiled a list of medications associated with high cholesterol. If you would like more information on a particular medication, the provided hyperlinks will direct you to ample documentation (e.g. typical dosage, side effects, drug-interaction risks, etc.).

PDRhealth The PDRhealth database is a free-to-use, drug information search engine that has been written for the public in layman’s terms. It contains FDA-approved drug information adapted from the Physicians’ Desk Reference (PDR) database. PDRhealth can be searched by brand name, generic name, or indication. It features multiple drug interactions reports. Search PDRhealth at http://www.pdrhealth.com/drug_info/index.html. Other Web Sites Drugs.com (www.drugs.com) reproduces the information in the Pharmacopeia as well as commercial information. You may also want to consider the Web site of the Medical Letter, Inc. (http://www.medletter.com/) which allows users to download articles on various drugs and therapeutics for a nominal fee. If you have any questions about a medical treatment, the FDA may have an office near you. Look for their number in the blue pages of the phone book. You can also contact the FDA through its toll-free number, 1-888-INFO-FDA (1-888-463-6332), or on the World Wide Web at www.fda.gov.

Coffee Break: Tutorials for Biologists17 Coffee Break is a general healthcare site that takes a scientific view of the news and covers recent breakthroughs in biology that may one day assist physicians in developing treatments. Here you will find a collection of short reports on recent biological discoveries. Each report incorporates interactive tutorials that demonstrate how bioinformatics tools are used as a part of the research process. Currently, all Coffee Breaks are written by NCBI staff.18 Each report is about 400 words and is usually based on a discovery reported in one or more articles from recently published, peer-reviewed literature.19 This site has new articles every few weeks, so it can be considered an online magazine of sorts. It is intended for general background information. You can access the Coffee Break Web site at the following hyperlink: http://www.ncbi.nlm.nih.gov/Coffeebreak/.
Other Commercial Databases In addition to resources maintained by official agencies, other databases exist that are commercial ventures addressing medical professionals. Here are some examples that may interest you: •
CliniWeb International: Index and table of contents to selected clinical information on the Internet; see http://www.ohsu.edu/cliniweb/.
•
Medical World Search: Searches full text from thousands of selected medical sites on the Internet; see http://www.mwsearch.com/.
17 Adapted 18
from http://www.ncbi.nlm.nih.gov/Coffeebreak/Archive/FAQ.html.
The figure that accompanies each article is frequently supplied by an expert external to NCBI, in which case the source of the figure is cited. The result is an interactive tutorial that tells a biological story. 19 After a brief introduction that sets the work described into a broader context, the report focuses on how a molecular understanding can provide explanations of observed biology and lead to therapies for diseases. Each vignette is accompanied by a figure and hypertext links that lead to a series of pages that interactively show how NCBI tools and resources are used in the research process.
99
APPENDIX B. PATIENT RESOURCES Overview Official agencies, as well as federally funded institutions supported by national grants, frequently publish a variety of guidelines written with the patient in mind. These are typically called “Fact Sheets” or “Guidelines.” They can take the form of a brochure, information kit, pamphlet, or flyer. Often they are only a few pages in length. Since new guidelines on high cholesterol can appear at any moment and be published by a number of sources, the best approach to finding guidelines is to systematically scan the Internet-based services that post them.
Patient Guideline Sources The remainder of this chapter directs you to sources which either publish or can help you find additional guidelines on topics related to high cholesterol. Due to space limitations, these sources are listed in a concise manner. Do not hesitate to consult the following sources by either using the Internet hyperlink provided, or, in cases where the contact information is provided, contacting the publisher or author directly. The National Institutes of Health The NIH gateway to patients is located at http://health.nih.gov/. From this site, you can search across various sources and institutes, a number of which are summarized below. Topic Pages: MEDLINEplus The National Library of Medicine has created a vast and patient-oriented healthcare information portal called MEDLINEplus. Within this Internet-based system are “health topic pages” which list links to available materials relevant to high cholesterol. To access this system, log on to http://www.nlm.nih.gov/medlineplus/healthtopics.html. From there you can either search using the alphabetical index or browse by broad topic areas. Recently, MEDLINEplus listed the following when searched for “high cholesterol”:
100 High Cholesterol
•
Other guides Heart Diseases http://www.nlm.nih.gov/medlineplus/heartdiseases.html Heart Failure http://www.nlm.nih.gov/medlineplus/heartfailure.html
You may also choose to use the search utility provided by MEDLINEplus at the following Web address: http://www.nlm.nih.gov/medlineplus/. Simply type a keyword into the search box and click “Search.” This utility is similar to the NIH search utility, with the exception that it only includes materials that are linked within the MEDLINEplus system (mostly patient-oriented information). It also has the disadvantage of generating unstructured results. We recommend, therefore, that you use this method only if you have a very targeted search. The NIH Search Utility The NIH search utility allows you to search for documents on over 100 selected Web sites that comprise the NIH-WEB-SPACE. Each of these servers is “crawled” and indexed on an ongoing basis. Your search will produce a list of various documents, all of which will relate in some way to high cholesterol. The drawbacks of this approach are that the information is not organized by theme and that the references are often a mix of information for professionals and patients. Nevertheless, a large number of the listed Web sites provide useful background information. We can only recommend this route, therefore, for relatively rare or specific disorders, or when using highly targeted searches. To use the NIH search utility, visit the following Web page: http://search.nih.gov/index.html. Additional Web Sources A number of Web sites are available to the public that often link to government sites. These can also point you in the direction of essential information.

Associations and High Cholesterol The following is a list of associations that provide information on and resources relating to high cholesterol: •
Inherited High Cholesterol Foundation Telephone: (801) 581-8720 Toll-free: (888) 244-2465 TTY: Fax: (801) 581-5402 Background: The Inherited High Cholesterol Foundation (IHCF) is a not-for-profit organization dedicated to promoting the early diagnosis and treatment of inherited cholesterol disorders by assisting in the identification of family members who may be predisposed to such disorders. Established in 1995 and currently consisting of approximately 5,400 members, the Foundation works in association with the MEDPED (Make Early Diagnoses and Prevent Early Deaths in Medical Pedigrees) program, an international collaboration consisting of research centers around the world dedicated to developing and implementing programs to identify affected individuals and their relatives. The Inherited High Cholesterol Foundation educates members of high risk families, health care providers, insurance companies, appropriate medical institutions and agencies, and the general public about inherited cholesterol disorders such as familial hypercholesterolemia, familial defective apoB, polygenic hypercholesterolemia, and familial combined hyperlipidemia. Individuals with such inherited conditions may be prone to highly elevated levels of cholesterol and an associated risk of early heart attack. The Inherited High Cholesterol Foundation also offers local support to affected individuals and family members and provides a variety of educational materials including pamphlets, brochures, leaflets, and newsletters.
Finding Associations There are several Internet directories that provide lists of medical associations with information on or resources relating to high cholesterol. By consulting all of associations listed in this chapter, you will have nearly exhausted all sources for patient associations concerned with high cholesterol. The National Health Information Center (NHIC) The National Health Information Center (NHIC) offers a free referral service to help people find organizations that provide information about high cholesterol. For more information, see the NHIC’s Web site at http://www.health.gov/NHIC/ or contact an information specialist by calling 1-800-336-4797. Directory of Health Organizations The Directory of Health Organizations, provided by the National Library of Medicine Specialized Information Services, is a comprehensive source of information on associations.
