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.

Cancer Will Soon Be Leading Cause of Death Worldwide, Avandia May Increase Fracture Risk in Diabetic Women, Warm-Up Exercises Reduce Injury Risk in Young Athletes
(December 10, 2008 - Insidermedicine) From Washington - According to ...
(December 10, 2008 - Insidermedicine) From Washington - According to the WHO's International Agency for Research on Cancer, heart disease will be surpassed by cancer as the leading cause of death worldwide by 2010. Experts have estimated that 12.4 million people will be diagnosed with some form of cancer this year, and 7.6 million will die. In men, the most common form is lung cancer, while breast cancer is the most pervasive form among women. From North Carolina - According to research published in the Canadian Medical Association Journal, diabetic women who take thiazolidinediones may be at increased risk for fracture. In a meta-analysis of 12 studies involving over 45,000 patients, researchers found that women taking drugs such as Avandia and Actos to control type 2 diabetes had a 45% increased risk of sustaining a fracture. This association was not seen in men. And finally, from Norway - According to research in the British Medical Journal, doing a set of warm-up exercises may significantly reduce the number of injuries that occur among young athletes. In a study of nearly 1,900 girls aged 13 to 17, researchers found that those who spent 20 minutes prior to a soccer practice doing strength, balance and jumping exercises, as well as stretching and running, sustained 29% fewer lower-extremity injuries than those that did not warm up.

Vitamin C and E Supplements Do Not Reduce Prostate Cancer Risk, Dexamethasone Increases Post-Op Bleeding Risk in Children, Women More Likely to Die From Serious Heart Attack Than Men
(December 9, 2008 - Insidermedicine) From Boston - According to ...
(December 9, 2008 - Insidermedicine) From Boston - According to research in the Journal of the American Medical Association, neither vitamin C nor E supplementation reduces the risk of prostate cancer. In a study of over 14,600 male physicians who were randomized to receive vitamin C or E supplements or a placebo, researchers found that those taking supplements did not have a lower risk of prostate cancer or other site-specific cancers such as colorectal, lung, bladder or pancreatic. From Geneva - According to another study in JAMA, the steroid medication dexamethasone, which is used to reduce nausea and vomiting after tonsillectomies, is linked with an increased risk for postoperative bleeding. In a study of 215 children undergoing tonsillectomy, researchers found that 24% of those who received 0.5 mg/kg of dexamethasone experienced postoperative bleeding, compared to only 4% of those who received placebo. And finally, from Houston - According to research in the journal Circulation, women who suffer from a serious heart attack are almost twice as likely to die than men. In a study of nearly 80,000 patients, researchers found that the in-hospital mortality rate for women who had suffered an ST-elevation myocardial infarction was 10.2%, compared to 5.5% for men. The researchers suggest that differences in patient characteristics and treatment are both likely contributing factors. For Insidermedicine in 60, I'm Allison Chow from Queen's University.

Half-Dose Flu Vaccine May Be Sufficient in Healthy Adults, Glaucoma Drug Approved As Cosmetic Product, Farsightedness Affects One Billion Worldwide
(December 8, 2008 - Insidermedicine) From Washington - According to ...
(December 8, 2008 - Insidermedicine) From Washington - According to research in the Archives of Internal Medicine, a half-dose of the flu vaccine may be all that is needed in healthy young adults. In a study of over 1,100 people, researchers found that those younger than 50 who had been previously vaccinated did not have a significantly different immune response to a half-dose, compared to those who received a full dose. The researchers suggest that this could be important in times of vaccine shortage. From Maryland - An FDA advisory panel has approved Allergan Inc.'s eye drug Lumigan as a cosmetic product. In a study of nearly 300 people, the drug, originally used to treat glaucoma, was found to increase eyelash length and thickness in 78% of those who received it, and will be marketed under the new trade name Latisse for this purpose. According to the company, the drug must be applied continuously or lashes will shrink to their original size within a few months. And finally, from Australia - According to research in the Archives of Ophthalmology, over 1 billion people worldwide are affected by presbyopia, more commonly known as farsightedness. Researchers also estimated that about 410 million with the condition are unable to perform tasks that require near vision, and 517 million have inadequate eyeglasses, or no eyeglasses at all. It is estimated that, by 2020, an additional 400 million people will be affected by this condition. For Insidermedicine in 60, I'm Dr. Susan Sharma.

Folic Acid Increases Respiratory Illness Risk in Infants, Treating Sleep Apnea Improves Cognition in Alzheimer's Patients, Many Americans Not Achieving Minimum Level of Exercise
(December 5, 2008 - Insidermedicine) From Norway - According to ...
(December 5, 2008 - Insidermedicine) From Norway - According to research in the Archives of Disease in Childhood, taking folic acid during pregnancy may increase the risk of respiratory illness in infants. In a study of over 32,000 children, researchers found that the offspring of women who had taken folic acid supplements during the first three months of pregnancy had a 24% increased risk of admission to hospital due to respiratory infection in the first 18 months of life. From California - According to research in the Journal of the American Geriatrics Society, treating sleep apnea in Alzheimer's patients may improve cognition. In a study of 52 elderly patients with mild-to-moderate Alzheimer's who also suffered from obstructive sleep apnea, researchers found that those treated for six weeks with continuous positive airway pressure (CPAP) experienced significant improvement on tests designed to assess verbal learning and memory, as well as cognitive control. And finally, from Atlanta - According to the CDC, a significant number of Americans are not achieving the minimum recommended level of exercise. It is recommended that adults get 150 minutes of moderate physical activity each week but, in a telephone survey of 399,000 adults, researchers found that one-third of people are not reaching that goal. The CDC has stated that about one-third of Americans are obese and another one-third are overweight. For Insidermedicine in 60, I'm Dr. Susan Sharma.

Liver Transplant Criteria Leaves Viable Patients Out, Those With Psychiatric Disorders Not Receiving Proper Treatment, High Sodium Levels Found in Many Processed Foods
(December 4, 2008 - Insidermedicine) From Italy - According to ...
(December 4, 2008 - Insidermedicine) From Italy - According to research in the Lancet Oncology, current criteria for evaluating liver cancer patients for transplantation may unnecessarily disqualify many. Under current standards, those with single liver tumors less than 5 cm or three or fewer tumors no more than 3 cm receive the highest priority. However, in a study of over 1,500 patients, researchers identified a subgroup with similar survival rates as those evaluated under the current criteria who are, nonetheless, sent to the back of the line. From California - According to research in the journal Psychiatric Services, many Americans suffer from psychiatric disorders, but few receive proper treatment. Researchers found that nearly 5% of the nation's population suffers from persistent depression or anxiety disorders yet a study of over 1,600 adults with a psychiatric disorder found that only 12% were receiving both medication and counseling, and only 22% had even consulted a mental health specialist. And finally, from Washington - According to research in Consumer Reports, high amounts of sodium can be found in many processed foods. In a study of 37 products, researchers found that foods such as breakfast cereal and bagels often contain high amounts of sodium. Meanwhile, in low-fat foods, sodium is often used to compensate for flavor. It is recommended that healthy adults get no more than 2,300 mg of sodium per day, and those with high blood pressure should aim for 1,500 mg or less. For Insidermedicine in 60, I'm Dr. Susan Sharma.

Brand Name Drugs No Better Than Generics, Asthma Risk Higher in Children Born By C-Section, Rheumatoid Arthritis Increases Risk of Cardiovascular Death
(December 3, 2008 - Insidermedicine) From Boston - According to ...
(December 3, 2008 - Insidermedicine) From Boston - According to research in the Journal of the American Medical Association, brand name drugs are no better than generic versions. In an analysis of 47 clinical trials covering 9 subclasses of cardiovascular drugs, researchers found no statistically significant difference between brand name and generic drugs. This comes despite the general notion among doctors and patients that brand names are more effective when in fact they are simply more expensive. From the Netherlands - According to research in the journal Thorax, asthma risk is higher in children born by cesarean section. In a study of almost 3,000 children who were followed up to age 8, researchers found that those born by c-section were nearly 80% more likely to be diagnosed with asthma than those delivered naturally. The increased risk rose to 200% among cesarean-born children with two allergic parents. And finally, from Vancouver - According to research in the journal Arthritis & Rheumatism, rheumatoid arthritis increases the risk of cardiovascular death. In an analysis of 24 clinical studies involving over 111,000 patients, researchers found that those with rheumatoid arthritis had a 59% increased mortality risk from ischemic heart disease, and a 52% increased mortality risk from stroke.

Too Much Media Exposure Leads to Health Issues Among Children, Drug-Eluting Stents Better Than Bare Metal, Smoking During Pregnancy Leads to Developmental Risks
(December 2, 2008 - Insidermedicine) From Washington - In an ...
(December 2, 2008 - Insidermedicine) From Washington - In an analysis of 173 studies, researchers from the National Institutes of Health and Yale University have found that spending too much time in front of the TV, playing video games, and surfing the Web increases the risk for many health problems among children. Overall, three-quarters of the studies found that increased media viewing was linked to negative health outcomes. One study in particular found that 3-year olds who spent more than 8 hours watching TV each week were more likely to be obese by age 7. From the Netherlands - According to research in the Journal of the American College Of Cardiology, drug-eluting stents are more effective than the bare metal variety, even among diabetics. In a study of over 1,800 patients, including over 250 with diabetes, researchers found that those who received drug-eluting stents had half the risk of heart attack, stroke or death as those who received bare metal stents. The researchers note that coronary artery bypass graft surgery is still more effective at reducing the need for repeat procedures. And finally, from France - According to research in the journal Sleep, smoking heavily during pregnancy increases the risk for developmental difficulties among preterm infants. In a study of 40 healthy preterm infants, researchers found that those who were born to mothers who smoked during pregnancy weighed less at birth by 11% if exposed to 10 or fewer cigarettes per day, and 21% if exposed to heavier smoking. It was also found that infants exposed to heavy smoking spent 18% less total time asleep. For Insidermedicine in 60, I'm Dr. Susan Sharma.

Experimental Compound to Prevent Heart Failure, Alcohol-Use Disorders Among College Students, Resveratrol Helps Restore Aging Chromosomes
(December 1, 2008 - Insidermedicine) From Germany - According to ...
(December 1, 2008 - Insidermedicine) From Germany - According to research in the journal Nature, an experimental compound may prevent heart failure. In a study of mice, researchers found that a genetic fragment called microRNA-21 plays a significant role in heart failure. Mice that were given the experimental compound antagomir, which suppresses the microRNA-21 gene, did not develop heart disease. In addition, those with heart failure that received the compound later showed improvement compared to those who did not receive treatment. From Maryland - In a study published in the Archives of General Psychiatry, researchers analyzed nearly 2200 college-attending individuals, and over 2900 individuals not attending college. They found that, while the overall rates of psychiatric disorders was similar in the two groups, college-attending individuals had a higher risk for alcohol use disorders. However, college students were less likely to have a diagnosis of drug use disorder, nicotine dependence or bipolar disorder. And finally, from Boston - According to research in the journal Cell, scientists have uncovered clues as to why resveratrol, an ingredient found in red wine, improves the health of laboratory mice. The researchers found that resveratrol activates a protein called sirtuin, which restores aging chromosomes to health. While further research is needed, the scientists are confident these findings could lead to drugs that will enhance resistance to disease and slow the aging process.

LVADs Do Not Improve Post-Surgery Survival, Continued Tocolysis Does Not Prolong Pregnancy, Universal HIV Testing Could Eliminate AIDS
(November 28, 2008 - Insidermedicine) From North Carolina - According ...
(November 28, 2008 - Insidermedicine) From North Carolina - According to research in the Journal of the American Medical Association, using ventricular assist devices to treat heart failure does not significantly increase survival. In a study of over 1,400 elderly patients who received LVADs following cardiac surgery, the one-year survival rate was 30%. Only 55% of those who received the devices as primary therapy survived initial hospitalization, and 55% of those were readmitted within 6 months From California - According to research in the journal Obstetrics & Gynecology, after premature labor is stopped, remaining on tocolysis does not prolong pregnancy. In a study of 68 women who were between 24 and 34 weeks' gestation, researchers found that continued treatment with nifedipine did not significantly improve the chances of reaching 37 weeks of gestation, and did not reduce the recurrence of preterm labor, when compared to placebo. And finally, from Geneva - According to research in The Lancet, a mathematical model suggests that the estimated number of AIDS deaths between 2008 and 2050 could be reduced by half. According to the model, a policy of universal HIV testing and immediate treatment for those positive with the virus could, in theory, lower rates of transmission because those on therapy are less infectious. The researchers suggest that annual incidence and mortality could fall to less than one case per 1,000 people within 10 years. For Insidermedicine in 60, I'm Dr. Susan Sharma.

Young People Unaware of Junk Food Health Effects, Serotonin Regulates Bone Mass, Naturally Produced Chemical May Lead to Obesity Treatments
(November 27, 2008 - Insidermedicine) From the UK - According ...
(November 27, 2008 - Insidermedicine) From the UK - According to a poll conducted by the British Heart Foundation, most young people are unaware of the potentially damaging health effects of junk food. In a study of over 1,100 children aged 8 to 15 years, 73% did not know that a poor diet could contribute to an early death. With about one-third of children under 16 currently overweight or obese, it is suggested that this generation may be the first to live shorter lives than their parents. From New York - According to research in the journal Cell, serotonin production in the gut has been linked to bone formation. In a study of mice, researchers found that serotonin, 95% of which is produced in the duodenum, acts as a hormone to regulate bone mass. This finding may lead to new medications and dietary approaches for treating bone diseases such as osteoporosis. And finally, from New Haven - According to another study in Cell, a chemical produced in the gut may lead to new treatments for obesity. In a study of mice, researchers found that a chemical messenger called NAPE, which occurs naturally in the small intestine, is released into the bloodstream after the consumption of fatty foods, traveling to the brain to shut down hunger signals. When mice were given extra NAPE for a period of five days, they ate less and lost weight. For Insidermedicine in 60, I'm Dr. Susan Sharma.
