Genetic Link Found For Bipolar Disorder

By | Diabetes, Mental Health, Prevention, Women’s Diseases

A staff psychiatrist at the Dalhousie Medical School in Halifax (Novia Scotia, Canada) has gathered 1100 DNA samples and psychiatric histories from patients with bipolar disorder and family members who do not have this psychiatric disease. Dr. Martin Alda, The Medical Post reports on page 46 of the May 20, 2003 edition, and his medical team were able to identify 4 areas of interest on chromosomes 15, 7, 6 and 21 where molecular markers for bipolar disease were located.

Two additional tools, namely responders to lithium (common bipolar disease stabilizer) and certain ethnic group differences, are being utilized as well. Dr. Alda has already found that unstable genes can be stabilized in the presence of lithium. By studying the genes involved in the expression of bipolar disorder and defining what triggers a depressive response and what triggers a manic episode, the researchers hope to unravel the mysteries that still surround this intriguing disease. Dr. Alda is also studying the connection of diabetes and biploar disease. Patients with biploar disease are 3 times more prone to diabetes than the general population. As these patients (bipolar patients with diabetes) are poor responders to lithium, there is a suggestion that perhaps the newly defined genetic loci are blocked in some way by the hormone changes in diabetics. Further investigations in this direction are planned by the research group.

Allergies, Asthma And Diabetes All Helped By Fish Oil

By | Allergies, Arthritis, Diabetes, Heart Disease

Cod liver oil was what your grandmother told you to take. It turns out she was right as two studies from Manchester/England and Boston/US have shown. The common denominator are omega-3-fatty acids, which are found in fish oil, cod liver oil, mackerel, salmon and other fish, generally speaking all sea food that feasts on plankton.

1. A prospective study with a cohort of 1100 children from before their birth until their 5th birthday, which will be next year, is being conducted in Manchester/England.

A smaller pilot study with 37 children (4-year-olds from this cohort) was recently analyzed as reported in Denver by Dr. Clare Murray, a pediatric lung specialist from the University of Manchester. The investigators have done detailed diet analyses with the help of the parents. They found that children with severe asthma were taking in a lot less omega-3-fatty acids than a healthy control group. Further analysis showed that the asthmatic group took in a lot of the inflammation provoking omega-6-fatty acids, whereas the control group had a much better balance between these two unsaturated fatty acids. Apparently it is the ratio between omega-6 to omega-3 fatty acids that determines whether the prostaglandin metabolism is switched versus pro-inflammatory (ratio more than 3 to 1) or versus anti-inflammatory (ratio 3 to1 or less). This article can be found in the Medical Post, Vol39, No.17 (page 19), April 29, 2003.

2. Another study is mentioned on the same page of the Medical Post: Dr. Frank Hu from the Harvard School of Public Health is the lead author of a study published in Circulation: Journal of the American Heart Association. 5103 female nurses with established type 2 diabetes have been followed for about 18 years and their medical histories, life styles and eating habits were updated every two years.

In the beginning of the study every patient was free of heart disease and cancer. The big surprise was that eating fish 5 times per week diminished the risk for developing heart disease by 65%. Even the women in the study who ate fish once or twice per week had 40% less heart disease than those who did not eat fish. In addition, fish eaters survived those who were not fish eaters much better (lower mortality). Controls of women without diabetes who ate fish five times per week had also a reduction of heart disease by 35% compared to non fish eating controls. Dr. Hu stated that it is the omega-3 fatty acids in fish that are the active ingredient. They are known to reduce irregular heart beats (arrhythmias) that can lead to sudden death. Omega-3 fatty acids also reduce blood fat levels (triglycerides), clot formation and improve blood vessel function. He also noted that both genders have the same benefit (no difference between male and female), just that the study was done on female nurses.

Comments: For your information the table below shows what foods contain omega-3 and omega-6 fatty acids.

Omega-3 and omega-6 fatty acids in our food
Type of unsaturated fatty acid: Foods that contain this type of unsaturated fatty acid:
omega-3 fatty acid flaxseed oil, walnuts, macadamia nuts, fishoil, canola oil, mackerel, salmon, sardines, tuna and most cold water fish
omega-6-fatty acid corn oil, cotton seed oil, grape seed oil, safflower oil, soybean oil and sunflower oil

In the past 50 years the food industry has changed the ratio of omega-6 to omega-3 fatty acids in many common foods to the point that the ratios are now 12 to 1 and up to 25 to 1. It is cheaper to produce these foods in that manner as they often have a longer shelve life. Read food labels. Inform yourself about omega-3 fatty acids. Take 2 capsules of a high strength, molecularly distilled (to remove PCB’s, mercury and other heavy metals) fish oil once per day and include more fish in your meals. Avoid deep fried foods, as they contain omega-6 fatty acids.

Framingham Study…Obesity And Smoking Lead To Loss Of Life

By | Diabetes, Fitness, Health, Heart Disease, Nutrition, Prevention, Stroke, Weight loss

The Netherlands Epidemiology and Demography Compression of Morbidity Research Group has published an important medical research paper in the Jan. 7, 2003 edition of the Annals of Internal Medicine (Ann Intern Med 2003;138:24-32).

The lead researcher, Dr. Anna Peeters, explained that the group has revisited the Framingham Heart Study 40 years later and analyzed survival statistics of the group of men and women who enrolled in this longterm study between 1948 and 1951. The population at the beginning of the study was aged between 30 and 49. The snap shot, after 40 years had elapsed, is the subject of this analysis. In order to make it easier to understand, I have tabulated the data as seen below.

This study shows that life style choices do matter: being overweight shortens your life by 3 years on average, being obese shortens it by 6 to 7 years.

Add the risk of smoking, and you end up shortening your life by 7 years in the case of being overweight (4 years more than without smoking) or more than 13 years, if you are obese.

Framingham Study...Obesity And Smoking Lead To Loss Of Life

Framingham Study…Obesity And Smoking Lead To Loss Of Life

This study was based on 3,457 participants who 40 years ago had a life expectancy of 85 years, if they were in the normal weight category and did not smoke.

The death rates were much higher than the researchers expected. The researchers from the Erasmus Medical Center in Rotterdam stated as a conclusion: ” just think about two things: Don’t get fat and don’t smoke”.

Years of life lost 40 years after Framingham Heart Study Was Started:
Non-smokers: Smokers:
  Male Female   Male Female
overweight *: 3.1 3.3 overweight*: 6.7 7.2
obese** : 5.8 7.1 obese ** : 13.7 13.3
* overweight:BMI = 25 to 29.9 ** obese:BMI = 30 and higher

The Liverpool Eye Study…How Often The Eye Sight Of Patients With Diabetes Should Be Examined

By | Diabetes, Eye Diseases

In the January 18, 2003 issue of the Lancet (Lancet 2003; 361:195-200) Dr. Dr. Naveed Younis and his collegues published a study from the Royal Liverpool University Hospital, U.K. where diabetic patients underwent thorough eye examinations in regular intervals for 5 years. The question of this study was whether it mattered at what interval patients would be examined with regard to their eye-sight, so that perhaps blindness could be postponed or avoided through early interventions.

At the baseline of the study a special eye-photography method (three-field mydriatic photography) was used to document the blood vessel changes in the back of the eye. This helps the physician to assess whether or not there is a degree of retinopathy (blood vessel damage from diabetes) of the eyes or not. The investigators defined three groups:

For group one (no eye damage in the beginning of the study) there was a retinopathy rate of 0.3% at the end of the first year. Group two (moderate retinopathy in the beginning) showed a worsening of the retinopathy at the end of the first year of 5% (threatening blindness). Group three (significant retinopathy in the beginning) showed a rate of 15% of worsening retinopathy (threatening blindness) at the end of one year.

This shows that not every person with diabetes is equal with respect of having the threat of blindness. The medical investigators found that about 70% of patients fell into the group that did not have serious diabetic retinopathy. However, the other 30% would not do well with simply yearly eye examinations as it is recommended now. Instead the authors of the Liverpool study were able to make practical recommendations as follows:

After a baseline eye examination those who belong into group one would get an eye examination every 3 years. Those with prior moderate retinopathy (group2) on the initial baseline examination would get examinations at yearly intervals (until the degree of retinopathy worsens). Group 3 with significant retinopathy at the beginning would, however, be examined every 4 months (new recommendation) so that blindness hopefully could be avoided or significantly postponed through interventional therapies.

New Research Shows That Coffee Drinking Is Healthy

By | Diabetes, Health, Heart Disease, Prevention

Forget what somebody may have whispered into your ear in the past,namely that coffee drinking would be bad for you. Dr. Rob M. van Dam and Dr.Edith J. M. Feskens from the National Institute for Public Health and the Environment in Bilthoven, theNetherlands, have recently completed a prospective study with a large number of participants.

The results were published in the Lancet 2002;360:1477-1478. The goal of the study was to see whether coffee consumption would have a positive or negative effect on the development of diabetes (type 2 or mature onset diabetes). Approximately 17,000 men and women were followed along over a period of time and 306 new cases of diabetes were detected. The average consumption of coffee was 5 cups per day. There was a striking difference between those who drank 7 cups of coffee per day and those who drank 2 cups or less per day: With 7 cups per day there was a 50 % LESSER risk of developing diabetes. The authors pointed out that it is known that some of the active ingredients in coffee are: the bioflavonoids, chlorogenic acid, the minerals magnesium and potassium, and vitamin B3.

Chlorogenic acid and magnesium have been known in the past to have a stabilizing effect on glucose metabolism thus preventing diabetes.The authors were surprised though about the magnitude of the diabetes protective effect. They suggested that
other authors should do further studies to confirm their findings and to attempt to pinpoint the mechanism of action. In the meantime they cautioned that it would be premature to recommend to increase coffee consumption for everybody.

Work Stress Is A Killer…More Than 2-Fold Over A Period Of 25 Years

By | Diabetes, Heart Disease, Obesity, Stroke

In mid October 2002 the British Medical Journal(BMJ 2002;325:p.857-860) published a paper by Dr. Mika Kivimäki from the University of Helsinki where 812 healthy factory workers were followed for about 25 years. The issue was whether stress from work would have negative consequences, which could be measured in terms of cardiovascular disease. Various risk groups were defined from low stress to high stress.

Low stress jobs were classified as people who often had more training, more responsibilities, better salaries, physically less strenuous jobs with more job security. High stress jobs involved the opposite(high demand/low job control/low salary/no job security). Depending on which subgroups of high versus low risks were compared, the investigators found a 2.2 to 2.4-fold increase of strokes and heart attacks due to cardiovascular disease.The team measured other cardiovascular risk factors. They found a significant increase of cholesterol in the high stress job group after 5 years. After 10 years there was a marked weight gain in the stressed group with obesity becoming much more frequent. The authors noted that this likely led to a change of metabolism in the sense of hyperinsulinism, which is known to cause high cholesterol levels and leads to hardening of the arteries with heart attacks and strokes.
