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.

(January 6, 2011 - Insidermedicine) From St. Louis - PSA screening may offer no mortality benefit, according to a report published in the Journal of the National Cancer Institute. Researchers followed men aged 55-74 for 13 years, randomizing participants to either PSA screening for 6 years or usual medical care. Results showed no mortality difference between the two groups. From Georgia - A new report released by the American Cancer Society finds that cancer death rates in the US continue to fall. Researchers noted a 1% decrease per year in cancer death rates from 1999 to 2008, particularly among the most common cancers--breast, prostate, lung and colon. And finally, from New Jersey - Hypothyroidism during pregnancy is more common than previously though, according to a report published in the Journal of Clinical Endocrinology and Metabolism. Studying over 115,000 women aged 18-40, researchers found that 15% suffered from gestational hypothyroidism. As a result, the researchers estimate the the condition may affect as many as 483,000 pregnant women a year

(January 4, 2012 - Insidermedicine) From Minnesota, researchers at the ...
(January 4, 2012 - Insidermedicine) From Minnesota, researchers at the Mayo Clinic have identified that liver scarring associated with Hepatitis C was a risk factor for liver cancer. Previously, liver scarring diseases associated with alcohol consumption were a known risk factor. Obesity was also found to account for 11% of liver cancer cases. From Boston, research appearing online in Nature shows great promise in preventing and controlling HIV infection. The scientists were able to partially protect monkeys from acquiring a virulent strain of Simian Immunodeficiency Virus (or SIV), a monkey version of HIV. Plans are underway to begin early-stage clinical trials in humans, but in the meantime this research confirms that scientists are homing in on some of the critical ingredients of a protective HIV vaccine. And finally, from St. Louis - Research published in PLoS Biology may have identified a genetic cause for deafness. Researchers found that inactivating the FGF20 gene in a mouse model resulted in completely healthy rodents that had no ability to hear.

(January 3, 2012 - Insidermedicine) From Pittsburgh - Stem cells given to aging mice significantly extended the rodent's lifespan, according to a report published in Nature Communications. Researchers injected stem cells derived from young, healthy mice into a mouse model that was engineered to age rapidly. They found that the stem cells dramatically improved the health of the mice and the rodent's lived 2-3x longer than expected. From Sweden - Bariatric surgery may reduce risk of deadly heart attack and stroke, according to a report published in JAMA. Researchers compared over 2000 obese individuals who underwent bariatric surgery to 2000 obese individuals treated with usual care. 15 year follow up revealed an association between the surgery and a reduction in fatal heart attacks and strokes. And finally, from Baton Rouge - Overconsumption of calories, not protein, increases body fat, according to a report published in JAMA. Researchers randomized 25 healthy individuals to over-consume varying levels of protein-diets. They found that those on the low-protein diets gained the least amount of weight, and that calories alone increased percentage of body fat

(December 16, 2011 - Insidermedicine) From Kingston - Research published in the New England Journal of Medicine finds that chemotherapy alone may improve survival in some blood cancer patients. Randomizing patients with Hodgkin's lymphoma to either chemotherapy alone, radiation plus chemotherapy, or radiation alone, researchers found that those treated with only chemotherapy were more likely to be alive a year after treatment started. From New York - Dentists could potentially screen nearly 20 million Americans for chronic health problems, according to a report published in the American Journal of Public Health. Researchers found that a significant portion of US adults and children routinely visit a dentist but not a health care provider. The authors suggest that dentists, as trained health care professionals, could potentially screen for diabetes and high blood pressure during the course of a normal visit. And finally, from Boston - A massive DNA study has found several gene abnormalities implicated in chronic lymphocytic leukaemia (CLL), according to a report published in the New England Journal of Medicine. Results of comprehensive DNA sequencing revealed five genetic mutations that were commonly associated with the blood cancer, an aspect which may improve predictions on progression of the diseas
