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.

(August 21, 2013 - Insidermedicine) From Australia - The flu shot greatly reduces risk of heart attack in middle aged adults with narrowed arteries, according to a report published in Heart. Researchers studied nearly 600 hospital patients over the age of 40, half of whom had of suffered a heart attack while the other half did not. Half of all patients received the flu shot. After controlling for factors such as cholesterol and smoking, researchers found that flu did not impact risk of heart attack. However, results showed that vaccination against the flu decreased risk of heart by 45%.

(August 20, 2013 - Insidermedicine) From Texas - Pilots who fly at high altitudes may be at increased risk of brain lesions, according to a report published in Neurology. Researchers studied 100 US Air Force Pilots , as well as 90 non-pilots. Participants were between 26-50 years old, and underwent MRI brain scans. Results showed that pilots who flew at 18,000 feet had almost 4x the volume and 3x the amount of brain lesions as non-pilots. As well, the pilots lesions were distributed throughout the brain, while the non-pilots lesions were mostly in the frontal white matter--as occurs in normal aging.

(August 19, 2013 - Insidermedicine) From Spain - Breastfeeding may delay breast cancer in non-smoking women, according to a report published in the Journal of Clinical Nursing. Researchers studied 500 breast cancer patients, aged 19-91. Results showed that women who underwent childbirth and breastfed developed breast cancer at a later age, regardless of family history of the disease. Women who didn't smoke and breastfed for more than 6 months were diagnosed with breast cancer an average of 10 years later than those who breastfed for a shorter period

(August 16, 2013 - Insidermedicine) From Singapore - Myopia may be a risk factor for cataract, according to a report published in the American Journal of Ophthalmology. Researchers conducted a meta-analysis of 12 studies, comprised of over 38,000 individuals between the ages of 30-97. Results showed that in 8 of the studies, myopia was associated with prevalent nuclear and posterior subcapsular cataract--but not cortical cataract. The remaining 4 studies found non-significant associations of myopia with age-related cataract.

Human eye movements quickly adapt to obstruction in vision

(August 15, 2013 - Insidermedicine) From California - A new report published in Current Biology finds that human eye movements quickly adapt when something obstructs vision. Researchers studied six young adults with normal sight, simulating a loss of foveal vision in the participants. Participants were then asked to complete visual-search tasks with this obstruction. After working on the task in three hours, participants quickly and spontaneously adjusted their eye movements. To compensate, participants adapted a consistent point on in their peripheral vision that served as their new point of gaze. Once this new point of gaze was established, it was retained for weeks afterwards--being activated when participant's foveal vision was blocked. This process may be able to help macular degeneration patients cope with vision loss.

(August 15, 2013 - Insidermedicine) From South Carolina - Drinking nearly 30 cups of coffee a week greatly raise risk of death in younger people, according to a report published in Mayo Clinic Proceedings. Researchers studied over 40,000 men and women, aged 20-87, taking part in the Aerobics Center Longitudinal Study. Participants submitted medical history questionnaires assessing their lifestyle habits, as well as their family history, during the 16 year follow-up period. Results showed that those who consumed more amounts of coffee were also more likely to smoke and had lower levels of cardiorespiratory fitness. Drinking more than 28 cups of coffee a week raised risk of dying from all causes by 21% in all of the participants. In those under 55 years of age, drinking more than 28 cups of coffee a week raised risk of all-cause mortality in people by 50%.

(August 14, 2013 - Insidermedicine) From Connecticut - According to a report published in Breast Cancer Research and Treatment, increased use of MRI for breast screening may lead to unnecessary invasive surgery. Researchers studied over 70,000 women who had been diagnosed with breast cancer from 2000-2009. During the study period, there was a significant increase in postoperative breast MRIs--use increased from 1% in 2000 to 25% in 2009. Results showed that women who did undergo the MRIs were also more likely to subsequently undergo more aggressive surgery. These results are significant, as the long-term benefits of aggressive breast surgery remain unclear

(August 14, 2013 - Insidermedicine) From Texas - The drug Finasteride may reduce risk of prostate cancer, according to a report released by the Cancer Therapy & Research Center at the University of Texas. Researchers studied 19,000 men, randomizing participants to placebo or to finasteride--a generic drug used to treat enlarged prostate and male pattern baldness. Participants had a median age of 62 and took the drug for 7 years. Results showed that the drug reduced risk of prostate cancer by 30% and risk of low grade tumours by 43%. Though there originally appeared to be an increased risk of high grade prostate tumours, this difference shrank in the follow-up period. As well, the 18 year follow-up found that the drug did not impact overall survival or risk of dying from prostate cancer.

(August 13, 2013 - Insidermedicine) From Sweden - A new report published in JAMA Internal Medicine finds that 9 risk factors from adolescence associated with young-onset dementia. Researchers studied nearly 500,000 Swedish men conscripted for military service between 1969 and 1979. Participants had an average age of 18 at the time their service began and were followed for a median of 37 years. During the study, nearly 500 men developed young-onset dementia (before the age of 65). Results showed that there were 9 significant risk factors for young-onset dementia: alcohol intoxication, stroke, antipsychotic use, depression, father's dementa, drug intoxication, low cognitive function at 18, low height at 18, and high systolic blood pressure at 18. Taken together, these factors accounted for 68% of the cases of young-onset dementia.
