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.

(September 15, 2009 - Insidermedicine) From Michigan - According to a study published in the Archives of Internal Medicine, female heart failure patients may not benefit from implantable defibrillators. Researchers studied several different heart studies from the past 60 years, analyzing data on nearly 1, 000 women who suffered advance heart failure. They found that women who had heart failure and had ICD's had no survival advantage over those without the device. From Atlanta - Most adult Americans are at risk for developing heart disease, according to a report published in the journal Circulation. Researchers collected data from decades of national health surveys, looking for the percentage of adults who had 5 low risk factors for heart disease; low cholesterol, no smoking history, good blood pressure, healthy weight and no diabetes. In 1994, 10.5% of adults had these factors and were at low-risk for heart disease, whereas in 2004, only 7.5% were at low risk. These numbers represent a sharp decline after decades of progress against heart disease risk factors. And finally, from Vancouver - According to a report published online in the journal Cancer, clinically depressed cancer patients may have an increased risk of mortality. Researchers investigated 32 different studies-- a total of nearly 12, 000 patients--analyzing the connection between depression and cancer mortality. Patients with symptoms of depression were at 25% increased mortality risk, while patients with clinically diagnosed depression were at an increased risk of 40%.

(September 14, 2009 - Insidermedicine) From Washington – Scientists have discovered that Methicillin-resistant Staphylococcus aureus (MRSA) can be found in public beaches and ocean waters, according to a report presented at the Interscience Conference on Antimicrobial Agents and Chemotherapy. Researchers found Staph bacteria on 9 of the 10 beaches that they studied in Puget Sound; over 50% of these samples were multidrug resistant. This study suggests that public beaches may be a source for transmission of MRSA. From Australia – According to a report published in the journal Hepatology, aerobic exercise lowers the risk of non-alcoholic fatty liver disease. Researchers studied 19 obese adults with sedentary lifestyles for four weeks. They found that regular cycling exercise resulted in 21% reduction of hepatic triglyceride concentration and a 12% reduction in visceral adipose tissue volume. These reductions occurred even if the participant did not lose any weight. And finally, from Washington – The FDA has approved the use of OVA1, a blood test used to discern between ovarian tumors and benign pelvic masses. The test, to be available later this year, showed a sensitivity of 85% to 96% in finding malignant masses. This test should help prevent otherwise unnecessary exploratory surgery.

(September 11, 2009 - Insidermedicine) From Australia - Young people have a very high risk for mortality, according to a report published in The Lancet. Studying global death rate statistics, researchers found that 2.6 million youths aged 10 to 24 are dying each year and that most of these deaths are preventable. 97% of these deaths occurred in low-to-middle income countries, while almost 40% occurred as a result of accidents or violence, specifically, war. From London - Unhappy children are more likely to become overweight later in life, according to a report published in the journal BMC Medicine. Researchers examined over 6,500 individuals who had participated in the 1970 British Birth Cohort study, measuring each persons weight and height at age 10 and again at age 30. Participants were also questioned on their emotional state. Results showed that those who had low self-esteem and worried excessively as children were more likely to be obese as adults. And finally, from Indianapolis - Doctors feel additional stress when they have to work with a patient's surrogate decision maker, according to a report published in the Journal of General Internal Medicine. Researchers studied nearly 300 doctors, 3/4 of which had dealt with surrogates shortly before the study began. 25% of doctors reported feeling significant stress working with surrogates. Ineffective communication and dissatisfaction with outcome of the decisions were the primary reasons cited for this stress.

(September 10, 2009 - Insidermedicine) From The Netherlands - According to research published in the journal BMC Family Practice, patients with upper gastrointestinal disorders are more likely to experience other illnesses as well. Researchers analyzed information on over 26, 000 people who had participated in a 2001 Dutch survey regarding patient presentations to primary care physicians. They found that patients with upper GI disorders visited their doctors twice as often as patients without these problems. From Sweden - The sound of traffic may increase the risk of high blood pressure, according to a report published in the journal Environmental Health. Swedish researchers surveyed over 24, 000 adults, gathering data regarding the average road noise near the participant's homes. Results showed that exposure to 60 decibels of traffic noise was strongly associated with hypertension. According to the report, most city people are exposed to at least 55 decibels of road noise. And finally, from Scotland - Researchers have identified the DNA information of the bacteria that caused the great potato famine in Ireland in the mid 1800s, according to a report published in the journal Nature. Scientists discovered that this pathogen--known as late blight--has a genome size that is twice as big as related species, an aspect that enables it to rapidly evolve and quickly destroy entire crops of its plant hosts. Late blight ravaged crops in Ireland in the 1850s, causing mass starvation, famine, and emigration.

(September 9, 2009 - Insidermedicine) From New York - According to research published in the Journal of the American Medical Association, a missing protein in the brain's reward center may be responsible for symptoms associated with attention deficit hyperactivity disorder (ADHD). Using positron emission tomography, researchers compared the brain scans of 53 adults with ADHD to 44 adults without the condition. Those with ADHD had lower levels of dopamine in their brain--proteins that are responsible for stimulation of reward and motivation. From Seattle - Smoking, obesity and alcohol consumption significantly increase a woman's risk of developing a second breast cancer, according to a report published in the Journal of Clinical Oncology. Researchers studied over 1,000 women who were diagnosed with primary estrogen receptor-positive breast cancer; 365 of these women developed a second breast cancer. Obese women had an increased risk of 50%; women who drank at least one alcoholic drink a day had an increased risk of 90%; and finally, current smokers were at an increased risk of 120%. And finally, from Washington - According to the Centers for Disease Control and Prevention (CDC), most people who get the flu this season will not require drugs. In an effort to prevent overuse of Tamiflu and Relenza, CDC officials are advocating that those with the flu should be carefully watched. Only those with severe illnesses or risk factors such as asthma and obesity are to be treated with antiviral medications.

(September 8, 2009 - Insidermedicine) From New York - Scientists have identified a virus that may increase a mans risk of prostate cancer, according to research published in the Proceedings of the National Academy of Sciences. Researchers compared over 200 prostate cancer tumors to 101 non-cancerous prostate tissue samples. They found that 27% of the tumors contained the virus XMRV--a virus that is known to cause other types of cancer in animals--compared to only 6% of the benign samples. From The Netherlands - New research suggests that the 'hygiene hypothesis'--a theory that maintains that early exposure to infections through daycare reduces ones risk of later illness--is false, according to a report published by the American Thoracic Society. Dutch researchers studied the respiratory symptoms of 4,000 children for the first eight years of their life. Results showed no beneficial or harmful effects of daycare--children who attended early were just as likely to wheeze later in life as those who did not. And finally, from the UK - Infections outside of the brain may increase an elderly persons risk of developing Alzheimer's Disease, according to a report published in the journal Neurology. Researchers studied over 200 elderly patients for a six month period; just over 100 of the patients developed different infections in places such as the chest, stomach, intestines and urinary tract. Those who developed these infections suffered memory loss twice as fast as patients who did not get infected or injured.

(September 4, 2009 - Insidermedicine) From San Francisco - Scientists have discovered antibodies that prevent HIV from becoming severe AIDS, according to a report published in the journal Science. Researchers examined the blood samples of over 1800 people who had HIV for at least three years and had not yet experienced progression of their infection. They found that two antibodies, PG9 & PG16, effectively prevented 162 different strains of HIV from multiplying and developing into severe disease. Scientists believe this discovery could potentially lead to an AIDS vaccine. From Illinois - According to a report published in the journal Obesity, late-night eating can lead to weight gain. Researchers fed two groups of mice at different times of the day; one ate when they would typically be sleeping, while the other ate at their regular feeding time. Even though both groups exercised the same amount and were fed equal portions of food, the group that ate late gained twice as much weight. And finally, from Washington - According to research from the American Institute for Cancer Research and the World Cancer Research Fund, a healthy lifestyle could help prevent a woman's risk of breast cancer. Researchers analyzed nearly 1000 studies that examined the links between lifestyle and breast cancer. Their analysis revealed that roughly 40% of breast cancer cases per year could be prevented with exercise, healthy weight, reduced alcohol consumption and breastfeeding.

(September 3, 2009 - Insidermedicine) From the Netherlands - Patients who undergo non-cardiac vascular surgery are much less likely to have consequent heart problems if they take cholesterol-lowering statins before and after the operation, according to a report published in the New England Journal of Medicine. Researchers enrolled almost 500 patients who were scheduled to have either their leg, neck or aorta artery unclogged--administering a placebo or a statin one month before and one month following the operation. Those who received the statin had half the risk of dying from a heart attack following their surgery. From Kansas City - According to a report presented at the Military Health Research Forum, what a pilot eats could potentially affect his/her flight performance. Researchers from the University of North Dakota studied 45 pilots for over 3 months, studying the affects that four different diets--a control diet, one high in carbohydrates, one high in protein, and one high in fats--had on their cognitive functioning. They found that both the carbohydrate and fat diets resulted in better simulated flight performances as well as improved sleep. And finally, from the UK - According to research published in the journal Current Biology, gene sequencing has revealed significant mutation in human DNA. Scientists studied two men in China who shared a common ancestor born in 1805. Using a new technique called direct sequencing--a process that counts the individual differences of nearly 10 million DNA units--researchers found several mutations of the Y chromosome. With these new numbers, scientists approximate that every human has 100 to 200 new mutations in their DNA.

(September 2, 2009 - Insidermedicine) From Hawaii - According to a report published in the journal Cancer Epidemiology, Biomarkers & Prevention, men who gain excessive weight in early adulthood may be at increased risk of eventually developing prostrate cancer. Researchers studied the health records of nearly 84, 000 men of varying ethnicities. Those who gained excessive weight after 21 were more likely to develop high-grade prostrate cancer later in life. From Cincinnati - Children with epilepsy are at increased risk of being obese, according to a report published in the journal Neurology. Researchers analyzed over 250 children with newly diagnosed epilepsy. Results showed that almost 40% of the epileptic children were overweight, while 20% were obese. And finally, from St. Louis - According to another study published in the journal Cancer Epidemiology, Biomarkers & Prevention, African Americans are more likely to die from pancreatic cancer than Caucasians. Evaluating data from the Cancer Prevention Study II, researchers analyzed pancreatic cancer disparities between African Americans and Caucasians. Results showed that, despite risk factors such smoking and obesity, African Americans were 32% more likely to die from the disease.

VIDEO: Adolescents Who Engage in Risky Behavior Likely Have More Mature Brains Than Previously Believed (Interview with Dr. Greg Berns, MD, PhD, Emory University)
(September 1, 2009 - Insidermedicine) Adolescents who engage in risky ...
(September 1, 2009 - Insidermedicine) Adolescents who engage in risky behavior are actually likely to have brains that are more mature than their cautious counterparts, according to research published in the August 26 issue of PLoS ONE. Some very risky activities that are currently popular among adolescents include: • The "choking game", in which children cut off oxygen to their own or someone else's brain until they pass out • "Car surfing", in which the child balances on the hood or roof of a moving vehicle • Carrying or brandishing weapons, including guns and knives Researchers from Emory University in Atlanta used a type of brain imaging technique known as diffusion tensor imaging (DTI) to measure the level of brain maturation of nearly 100 adolescents aged 12 to 18 over a three year period. The researchers also surveyed the teens about how much they engage in risky behavior such as thrill seeking; recklessness; rebelliousness, and antisocial behaviors. Those who engaged in the most risky behavior were more likely to have highly developed white matter, which is a sign of a more mature brain. There were no differences between the boys and girls with respect to brain maturation, although the boys were slightly more likely to engage in risky behavior. Today's research calls into question the theory that adolescents and young adults engage in impulsive and risky behaviors because their brains are not fully mature.
