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.

(March 28, 2012 - Insidermedicine) From St. Louis - Over 50% of all cancer cases are preventable, according to a review published in Science Translational Medicine. The study authors point out that tobacco is responsible for 33% of all cancer cases in the US, while obesity is linked to another 20%. The authors believe that the cancer burden can be greatly reduced with both lifestyle and societal change and making disease prevention a priority. From BC - Stopping statin therapy in rheumatoid arthritis patients raises risk of death, according to a report published in Arthritis Care & Research. Studying over 37,000 RA patients, researchers found that discontinuing statin therapy raised risk of dying from heart disease by 60%, and raised risk of dying from all causes by 79%. From Maryland - A new report published in the NEJM finds that losing weight and increasing fitness greatly improves mobility in adults. Researchers studied nearly 5,200 adults randomly assigned to an intensive lifestyle intervention group or one that simply attended meetings 3x a year. Results showed that adults in the intensive intervention group had a nearly 50% reduction in mobility related disability.

(March 26, 2012 - Insidermedicine) From London - Scientists have discovered the process that causes normal cells to turn into cancer cells, according to a report published in PLoS ONE. Researchers examined FOXM1--a gene present in almost all human cancers--and found that the gene brainwashes normal cells into adopting the memory patterns of cancer cells. This discovery may lead to a diagnostic test able to detect cancer in it's earliest stages. From San Francisco - Research published in the Archives of Neurology connects blood biomarkers to risk of Alzheimer's disease. Results of a meta-analysis comprised of 13 studies and over 10,000 individuals found that elevated plasma levels of amyloid-β (Aβ) peptides greatly raised risk of dementia and Alzheimer's disease. From Cleveland - A new report published in the Archives of Internal Medicine finds that warfarin is associated with only a low risk for stroke. Studying nearly 10 randomized trials and over 32,000 individuals, researchers found that the blood thinner had an incident rate of 1.66%--lower than previously believed

(March 22, 2012 - Insidermedicine) From the Netherlands - A new genetic test may be able to spare breast cancer patients from unnecessary chemotherapy, according to a report presented at the European Breast Cancer Conference. Researchers studied the genetic signatures of breast tumours in over 400 patients using the Mammaprint® test. They found that the test accurately identified which patients were at low risk of local recurrence following their surgery, sparing their need for chemotherapy without adversely affecting long term survival. From Montreal - Antidepressants during pregnancy may raise blood pressure, according to a report published in the British Journal of Pharmacology. Comparing over 1,200 women with pregnancy induced high blood pressure to over 12,000 healthy controls, researchers found that use of SSRIs during pregnancy increased relative risk of hypertension by 60%. From New York - Prenatal exposure to air pollution may raise risk of behavioural problems in the child, according to a report published in Environmental Health Perspectives. Researchers followed over 200 women who gave birth between 1999-2006 and examined their exposure to polycyclic aromatic hydrocarbons (PAH). They found that elevated exposure to the air pollutant during pregnancy greatly raised risk of anxiety and attention problems in the child.
