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.

New 3D breast imaging technique has 25x less radiation; Quitting smoking before 30 can add 10 years to a woman's life
(October 27, 2012 - Insidermedicine Week in Review) From Los ...
(October 27, 2012 - Insidermedicine Week in Review) From Los Angeles - Scientists have developed a new method of x-ray imaging that greatly lowers radiation exposure during breast scans, according to a report published in PNAS. A multidisciplinary team of radiologists, mathematicians and physicists developed a way to enhance the spatial resolution of conventional imaging by 2-3x. In addition, the imaging exposes the breast to a 25x reduced radiation dose. From the UK - Women who quit smoking around age 30 can drastically reduce their excess risk of premature death, according to recent results from the Million Women Study published in the Lancet. The study was comprised of 1.3 million women--recruited for participation between 1996 and 2001 and followed up for an average of 12 years. 66,000 participants died during the study period. Results showed that women who were smokers 3 years into the study period had nearly 3x increased risk of dying over the following 9 years, with risk of death increasing with the amount of cigarettes smoked. Researchers also found that women who successfully quit smoking prior to 30 years of age avoided 97% of their excess death risk, while serious health risks remained for decades among women who smoked until 40. Excess health risks were raised 10x for women who smoked after age 40. Professor Sir Richard Peto, co-author of the study, had this to say: "If women smoke like men, they die like men – but, whether they are men or women, smokers who stop before reaching middle age will on average gain about an extra ten years of life."

(October 26, 2012 - Insidermedicine) From the Netherlands - Research published in the American Journal of Respiratory and Critical Care Medicine finds that older COPD patients are at raised risk of carotid artery plaque formation--a disease that can cause stroke and death. Researchers from Erasmus Medical Center in Rotterdam studied 1,100 individuals over the age of 55, 253 of whom had COPD and over 900 of whom were controls. Study participants received spirometry to confirm COPD, ultrasound to identify carotid wall thickening and MRI to identify carotid plaques. Ultrasound revealed that COPD patients were 2x more likely than controls to have carotid wall thickening and significantly more likely to have plaque formation on MRI. According to Dr. Bruno Strocker, lead author of the study, these results "can help identify those at high risk and lead to the development of more personalized preventive treatment strategies targeting this devastating complication."

(October 25, 2012 - Insidermedicine) From the UK - Smoking significantly reduces life expectancy in Japan, according to a report published in the BMJ. Researchers studied over 68,000 men and women who survived the atomic bombing of Hiroshima or Nagasaki with minimal radiation exposure, following the participants for 23 years. They found that smoking reduced life expectancy by 10 years, and that the younger an individual started smoking, the higher their risk of death

Hormone therapy may lower Alzheimer's risk in women; Sleep deprivation linked to obesity; New guidelines mean millions of Americans will no longer need vitamin D supplements
(October 24, 2012 - Insidermedicine) From Baltimore - Research published ...
(October 24, 2012 - Insidermedicine) From Baltimore - Research published in Neurology finds that hormone therapy may reduce risk of Alzheimer's disease in women. Studying nearly 1,800 elderly women for 11 years, researchers found that those who began hormone therapy within 5 years of menopause had a 30% reduced risk of Alzhiemer's disease when compared to those who did not use the therapy. From Pennsylvania - Partial sleep deprivation may be associated with obesity, according to a report published in the Journal of the Academy of Nutrition and Dietetics. Results of a meta-analysis examining studies from 1996-2011 found that sleep deprivation causes changes in hormone levels that promote hunger. From Chicago - New guidelines could mean millions of Americans will no longer need vitamin D supplementation, according to a report published in PLoS ONE. Based on data from nearly 1,000 studies, the Institute of Medicine lowered the amount of vitamin D considered to be sufficient from 30 ng/ml or above to 20 ng/ml or above. The change means that nearly 80 million adults would no longer be considered vitamin D insufficient and would no longer have to take supplements.

(October 23, 2012 - Insidermedicine) From Boston - Certain risk factors raise a man's risk of peripheral artery disease, according to a report published in JAMA. Researchers followed nearly 45,000 men for over 20 years, finding that those with at least one risk factor of high cholesterol, high blood pressure, type 2 diabetes and smoking were at raised risk of PAD, while every additional risk factor raised risk twofold. Men with none of the 4 risk factors were at 77% reduced risk of the disease. From London - Removing age restrictions on the rotavirus vaccine could save many lives, according to a report published in PLoS Medicine. Currently, only infants under the age of 32 weeks can have the vaccine, as age raises risk of intussusception--a deadly form of bowel obstruction that can occur following vaccination. However, removing the age restriction on the vaccine in low and middle income countries would prevent an additional 47,000 deaths from the rotavirus while only causing 294 additional deaths from intussusception. From California - Research published in Gastroenterology links declining colorectal cancer rates to increased use of colonoscopy. Studying 20 years of data on over 2 million patients, researchers found that a significant decline in colorectal cancer in the past 10 years coincided with widespread colonoscopy screening for the disease.
