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.

BREAST CANCER VIDEO: Breast Cancer Screening Option for Women at High Risk, New Approach To Reduce Stroke Damage, Cochlear Implant Good for Deaf Child's Quality of Life
(February 24, 2010 - Insidermedicine) From Boston - According to ...
(February 24, 2010 - Insidermedicine) From Boston - According to a report published in the journal Radiology, young women at high risk for breast cancer may benefit from yearly combined screening of mammography and MRI. Researchers estimated the number of quality adjusted life years that high risk women would gain from annual combined screening, finding that these women could gain up to 50 QALYs. From San Antonio - A new approach to reducing stroke damage has been presented at the International Stroke Conference. Researchers are examining a new field of study--known as ischemic preconditioning--in which blood supply to a particular organ is purposely reduced in an effort to prepare the organ's tolerance of operating with limited blood supply. Researchers believe that using a blood pressure cuff, for example, could condition the brain to operate in such a way that would thereby reduce damage incurred by a stroke. And finally, from Dallas - According to a report published in Otolaryngology – Head and Neck Surgery, cochlear implants appear to improve the quality of life in deaf children. Researchers surveyed nearly 100 families of deaf children with cochlear implants, finding that the implants gave the children a quality of life equal to their peers, and that the earlier the device was implanted, the more likely the child was to experience these benefits.

(February 19, 2010 - Insidermedicine) Skiers and snowboarders should take a tip from bikers and start making helmets the norm rather than the exception, according to a commentary published in the Journal of the American Medical Association. While the effects of brain injuries vary depending on the precise area and type of damage, typical consequences include: • Memory loss • Impaired reasoning skills • Paralysis or loss of vision/hearing Experts in neurosurgery from St. Michael's Hospital in Toronto are using cold, hard facts to encourage skiers and snowboarders to don helmets. They point out that head injuries are the leading cause of hospital admission and death related to these sports and that about 120,000 head injuries occur each year in North America alone among those engaging in them. Wearing a helmet can reduce the risk of head injury by up to 60%, but the current culture among skiiers and snowboarders is not to wear them. The authors recommend some strategies for encouraging helmet use among the public. These include having snowboarders and skiers appearing in advertising wear helmets, having parents wear helmets to promote it among their children, and providing formal instruction on the importance of helmet-wearing at resorts, schools, and other groups. Today's commentary indicates that the smart skiers and snowboarders, such as the Olympic contenders, wear helmets.

Researchers compared 21 women with multiple sclerosis to 15 healthy controls, finding that the fitter the MS patient, the better they scored on cognitive functioning tests. MRI scans revealed that aerobic fitness had a protective effect on the specific parts of the brain damaged by MS. From Hong Kong - According to a report published in the Journal of Agricultural and Food Chemistry, green tea may be able to protect against common eye conditions. Researchers gave lab rats green tea, finding that the antioxidants in green tea were indeed capable of passing from the stomach into eye tissues. As a result, the eye was temporarily relieved of oxidative stress. And finally, from Rochester - Postpartum depression appears to be more prevalent among low-income urban mothers, according to a report published in the journal Pediatrics. Studying nearly 200 low income mothers whose children were under 14 months old, researchers found that 56% of participants had symptoms of minor or major depression.
