April 25, 2007 Patients with HIV who are treated with protease inhibitors have an increased risk of heart attack, according to a study published in the New England Journal of Medicine. Combination antiretroviral therapy has had a dramatic effect in reducing illness and death associated with the HIV virus, however an earlier study showed that the risk of heart attacks increased by 17% with every year a patient spent on antiretroviral. It isn’t known, though, whether all antiretroviral drugs carry this risk. The assessment of the role of any specific drug is difficult because patients with HIV usually receive a combination of drugs, and often switch regimens because of the availability of newer substances, adverse events, or drug regimen failure. Previous studies have shown a relationship between the use of protease inhibitors, a class of antiretroviral drug, and cardiovascular disease, but there is little information on the risks associated with another class of antiretroviral therapy called nonnucleoside reverse-transcriptase inhibitors. In this study, more than 23,000 patients infected with the HIV virus were assessed to determine the incidence of heart attack and the association between heart attack and exposure to protease inhibitors or nonnucleoside reverse-transcriptase inhibitors. Confirming the earlier results, the researchers found the risk of having a heart attack increased by 16% per year of exposure to protease inhibitors alone, which is equal to twice the risk over five years. Not such effect was observed with nonnucleoside reverse-transcriptase inhibitors. It is thought that protease inhibitors raise the level of blood lipid, thereby increasing the risk of cardiovascular disease and heart attack. Patients treated with protease inhibitors should have their cholesterol and blood pressure levels monitored, and take steps to reduce their lifestyle-related risk factors. This includes maintaining a healthy weight, eating a low-fat diet rich in fruits in vegetables, and getting regular exercise. Reporting for Insidermedicine, I'm Dr. Susan Sharma.

VIDEO: FDA Issues Peanut Butter Product Warning, First-Time Heart Attacks Less Fatal Today, Calm Disposition Lowers Dementia Risk
(January 20, 2009 - Insidermedicine) From Maryland - The FDA ...
(January 20, 2009 - Insidermedicine) From Maryland - The FDA has warned the American public to avoid all food products containing peanut butter. The ongoing salmonella outbreak has already sickened 474 people in 43 states, as well as one person in Canada. Currently, the recommendation does not apply to name-brand jars of peanut butter available in grocery stores, but rather peanut butter-containing food products such as cookies, crackers, cereal and ice cream. From Chicago - According to research in the journal Circulation, first-time heart attacks are less likely to be fatal today than they used to be. According to a study of over 10,000 first-time heart attack patients, researchers found that heart disease deaths have fallen by 30% in the last decade. The authors suggest that better control of cholesterol and blood pressure, declining smoking rates and improved medical treatments have led to this trend. And finally, from Sweden - According to research in the journal Neurology, having a relaxed and outgoing personality may help prevent dementia. In a study of over 500 older adults, researchers found that the risk of dementia was 50% lower among those who identified themselves as calm and outgoing, compared to those prone to social isolation or neuroticism. Exercising, socializing, problem solving and eating a healthy diet are all considered ways to help protect against dementia.

VIDEO: Genetic Variants Help Predict Obesity, Lucentis Outperforms PDT for Macular Degeneration Treatment, Moderate Alcohol Consumption Offers Benefits for Healthy Adults
(January 19, 2009 - Insidermedicine) From London - According to ...
(January 19, 2009 - Insidermedicine) From London - According to research in the journal Nature Genetics, newly found genetic variants may help predict obesity. In a study of nearly 2,800 people, researchers discovered three genetic mutations that were significantly linked to obesity. The researchers suggest that these variants could account for up to 50% of cases of severe obesity. Further research could lead to new screening techniques to find out who is at highest risk of becoming obese. From Baltimore - According to research in the Archives of Ophthalmology, Lucentis outperformed photodynamic therapy for the treatment of neovascular age-related macular degeneration. In a study of over 400 patients, researchers found that those treated monthly with 0.5 mg of Lucentis reported an improvement of 8.1 points on a visual function questionnaire, compared to those who underwent photodynamic therapy, who reported an improvement of only 2.2 points. And finally, from Los Angeles - According to research in the American Journal of Epidemiology, light to moderate alcohol consumption may provide benefits for healthy older adults. In a study of over 4,200 people aged 50 and older, those who were healthy and drank fewer than 15 drinks per week had a 17% chance of becoming disabled or dying in 5 years, compared with 26% among those who did not drink. This benefit was not seen in those who rated their health as fair or poor. For Insidermedicine in 60, I'm Dr. Susan Sharma.

VIDEO: Schizophrenia and Bipolar Disorder Share Genetic Roots, Short-Term Placebo Use Not Harmful in Adolescent Depression, STD Rates Rising in U.S.
(January 16, 2009 - Insidermedicine) From Sweden - According to ...
(January 16, 2009 - Insidermedicine) From Sweden - According to research in The Lancet, schizophrenia and bipolar disorder share a genetic cause. Researchers compared patient discharge data for schizophrenia and bipolar disorder with a register of over 2 million families and found that the disorders share genetic roots. For example, having a parent with schizophrenia raised the risk of a person developing the condition by nearly 10 times, and the risk of developing bipolar disorder by over 5 times. From Texas - According to research in the American Journal of Psychiatry, short-term placebo for adolescent depression does not result in long-term harm. In a study of over 400 adolescent patients, researchers found that those who took a placebo for 12 weeks before starting active treatment saw no difference in response rate after 36 weeks compared to those on active treatment from the start. The authors warn that delaying treatment in non-research settings is not ethical or clinically appropriate And finally, from Atlanta - According to the CDC, sexually transmitted diseases are on the rise in the U.S. In 2007 there was a record-setting 1.1 million cases of chlamydia reported. In addition, the number of reported cases of syphilis rose modestly, while cases of gonorrhea stayed the same. While this increase is most likely due to better screening, researchers suspect that, including unreported cases, as many as 2.8 million Americans get chlamydia each year.

Surgery Checklist Reduces Deaths and Complications, Childhood Diet May Predict Adulthood Obesity Risk, IVF Reverses Infertility in Younger Couples
(January 15, 2009 - Insidermedicine) From Boston - According to ...
(January 15, 2009 - Insidermedicine) From Boston - According to research in the New England Journal of Medicine, introducing a Surgical Patient Safety Checklist can reduce deaths and complications from surgery. In an international study of eight hospitals and about 7,700 patients, researchers found that introducing a safety checklist reduced the rate of death from 1.5% to 0.8%. Furthermore, the rate of inpatient complications was reduced from 11% to 7%. From Calgary - According to research in the Journal of Physiology, there is a connection between childhood diet and the future risk of becoming obese. In a study of rats, researchers found that those fed a protein-heavy diet in their youth gained more weight when fed a high-sugar, high-fat diet in adulthood than rats who had been fed a high fiber diet at a young age. The researchers suggest that a high fiber diet causes an increase in the activity of a gene that controls the release of hormones that make one feel full. And finally, back to Boston - According to a study in the New England Journal of Medicine, in vitro fertilization may reverse infertility in younger couples. In a study of over 6,000 women, researchers found that those younger than 35 who had undergone six cycles of IVF had cumulative live birth rates between 65% and 86%, which is similar to rates reported in the general population. However, IVF did not seem to reverse the age-dependent decline in fertility after age 40. For Insidermedicine in 60, I'm Dr. Susan Sharma.

(January 14, 2009 - Insidermedicine) From the UK - According to research in the journal Personality and Individual Differences, high caffeine intake may increase the chance of experiencing hallucinations. In a study of over 200 university students, researchers found that having the equivalent of 8 or more cups of coffee a day resulted in a 3 times higher risk of hallucinations, such as hearing voices. While hallucinations are often symptoms of schizophrenia, they can also occur in healthy individuals. From Boston - According to research in Circulation: Cardiovascular Quality and Outcomes, women with cardiac symptoms are more likely to experience delays on the trip to the hospital than men. In a retrospective study of over 5,800 patients, researchers found that women were 52% more likely to be delayed 15 minutes past the median time of 34 minutes in EMS care. The researchers suggest that differences in symptom presentation between men and women may be the cause. And finally, back to the UK - According to research in the Journal of Clinical Endocrinology and Metabolism, smoking during pregnancy may cause potentially harmful changes in thyroid function. In a study of over 2,300 pregnant women, researchers found that smokers experienced changes in thyroid hormone levels. These changes were also detected in the newborns of these women. The thyroid hormone levels among women who quit smoking during pregnancy were comparable to those of nonsmokers. For Insidermedicine in 60, I'm Dr. Susan Sharma.

Sodium-to-Potassium Ratio Predicts Heart Disease Risk, HRT Linked to Faster Brain Tissue Loss, Cold Weather Increases Blood Pressure in Older Adults
(January 13, 2009 - Insidermedicine) From Boston - According to ...
(January 13, 2009 - Insidermedicine) From Boston - According to research in the Archives of Internal Medicine, the urinary excretion ratio of sodium to potassium may predict heart disease risk. In a study of nearly 3,000 people, researchers found that, compared with a normal ratio, the highest sodium-potassium ratios indicated a 50% increased risk of cardiovascular disease. That is, too much sodium and too little potassium may increase the risk of stroke, heart attack and other cardiovascular events. From Washington - According to research in the journal Neurology, hormone therapy has been linked to faster loss of brain tissue in older women. In a study of over 1,400 women over the age of 70, researchers found that those undergoing hormone replacement therapy experienced faster loss of brain tissue in areas responsible for thinking and memory. Typically, HRT is not recommended for women over the age of 65. And finally, from Paris - According to research in the Archives of Internal Medicine, cold weather can increase blood pressure in older adults. In a study of 8,800 patients aged 65 and older, researchers found that systolic blood pressure rose an average of 5 mm Hg as temperatures dropped from summer to winter, and hypertension rates rose from 24% to 33%. These findings may help explain seasonal variation in rates of stroke, blood vessel rupture, and aneurysm. For Insidermedicine in 60, I'm Dr. Susan Sharma.

(January 12, 2009 - Insidermedicine) From the Netherlands - According to research in BMC Public Health, weight loss counseling delivered by phone or e-mail appears to be effective. In a six-month study of nearly 1,400 patients, researchers found that those who received a phone call from trained counselors every 2 weeks lost 1.5 kg compared to a control group who only received brochures. Patients who were contacted by e-mail lost 0.6 kg compared to the control group. From Maryland - An FDA advisory panel has recommended approval of the anti-seizure drug Sabril (vigabatrin) for infantile seizures. Despite evidence that the drug is associated with a risk for peripheral vision loss, the advisory panel concluded that the benefits of the drug outweigh the potential risks. If the FDA decides to move forward with approval, Sabril would become the first drug approved to treat infantile spasms. And finally, from London - According to research in the British Journal of Psychology, exposure to testosterone in the womb may increase the risk for autism in children. Researchers recorded testosterone levels in the amniotic fluid of 235 pregnant women and compared the results with questionnaires designed to measure autistic traits among 6 to 10 year olds. The researchers found that high levels of testosterone were linked with a higher likelihood of exhibiting autistic traits. For Insidermedicine in 60, I'm Dr. Susan Sharma.

(January 9, 2009 - Insidermedicine) From London - According to ...
(January 9, 2009 - Insidermedicine) From London - According to research in the journal Cell Stem Cell, a new technique may help the body repair itself with stem cells. In a study of mice, researchers found a way to cause bone marrow to make extra adult stem cells, allowing the body to produce its own repair kit that could potentially mend broken bones and fix damaged heart tissue. Another application may be to produce extra immune suppressing stem cells to treat autoimmune diseases. From Minnesota - According to research in Cancer Epidemiology, Biomarkers & Prevention, the risk of colorectal cancer is lower among women undergoing hormone therapy. In a study of nearly 1,000 postmenopausal women, researchers found that those who received combined estrogen therapy had a 22% reduced risk for colorectal cancer, compared to those who did not receive hormone therapy. The risk reduction was 36% among those who received sequential therapy. And finally, from Calgary - According to research in the journal Neurobiology of Aging, women who stay physically fit also remain mentally fit. In a study of 42 women with an average age of 65, researchers found that, compared to a sedentary group, those who participated in regular aerobic activity had 10% lower resting blood pressure, 5% better blood flow to the brain, and scored 10% higher on cognitive skill tests.

(January 8, 2009 - Insidermedicine) From Belfast - According to research in the British Journal of Cancer, skin cancer increases the risk of developing additional cancers. In a study of 23,000 people treated for skin cancer, researchers found that the risk of developing a new cancer was double in those with melanoma. The increased risk was for other types of skin cancer, and smoking-related cancer. About 60% of melanomas and 90% of non-melanoma skin cancers come from UV exposure. From Alabama - According to research in the New England Journal of Medicine, early repeat cesareans increase the risk of complications. In a study of over 13,000 women, researchers found that elective repeat cesareans done before 39 weeks of gestation lead to a higher risk of the baby suffering from complications including respiratory distress and requiring admission to the NICU. Between 1996 and 2006, the rate of cesarean births in the U.S. increased from 20% to 31%. And finally, from Atlanta - According to a study published in the CDC's National Vital Statistics Reports, the teen birth rate in the U.S. has risen for the first time in 15 years. According to the study, the birth rate among girls aged 15 to 19 increased by 3% in 2006. The states with the highest rates were Mississippi, New Mexico and Texas at over 60 births per 1,000 girls. New Hampshire, Vermont and Massachusetts had the lowest rates at around 20 per 1,000. For Insidermedicine in 60, I'm Dr. Susan Sharma.

Drug Combination Increases Effectiveness of Leptin, Grape Seed Extract Aids Leukemia Cell Death, Higher Aggression Observed Among Children of Pregnant Smokers
(January 7, 2009 - Insidermedicine) From Boston - According to ...
(January 7, 2009 - Insidermedicine) From Boston - According to research in the journal Cell Metabolism, the failed anti-obesity drug leptin may be useful after all. In a previous study, leptin did not produce the desired outcome in obese patients, who developed a resistance to its effects. However, in a new study of mice, researchers have found that using drugs that re-sensitize the brain to leptin allows for significant weight loss, and has renewed hopes of using leptin as a natural treatment for obesity. From Kentucky - According to a study in Clinical Cancer Research, grape seed extract may have benefits for the treatment of leukemia. Researchers have found that grape seed extract can cause leukemia cell death by activating certain proteins involved in apoptosis. In the study, the researchers discovered that a 10 mcg/mL dose of extract moderately increased leukemia cell death, while a 25 mcg/mL dose increased cell death extensively. The extract had no effect on healthy cells. And finally, from Montréal - According to research in the journal Development and Psychopathology, children of pregnant smokers are more likely to be aggressive. In a study of over 1,700 children, researchers found that the children of mothers who smoked at least 10 cigarettes a day had a 30% increased risk of high physical aggression than the children of women who did not smoke during pregnancy. It is estimated that about 25% of women in Québec still smoke during pregnancy. For Insidermedicine in 60, I'm Dr. Susan Sharma.
