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.

    Eating less salt can have tremendous health benefits worldwide

    (April 4, 2013 - Insidermedicine) From London - According to ...

    (April 4, 2013 - Insidermedicine) From London - According to three studies published in BMJ, reducing salt and increasing potassium in the diet can have great health benefits worldwide. The first study, a meta-analysis covering 34 trials and over 3,000 adult men and women, found that a modest reduction of salt consumption in a month or more greatly reduced blood pressure in those with high and normal blood pressure. The second study, examining 56 trials, also found that reducing salt intake lowers blood pressure levels with no adverse effect on lipids, kidneys, or hormone levels. Finally, the this study examined data from 33 trials pm per 128,000 adults and found that increased potassium intake--found in most fruits and vegetables--lowered blood pressure with no adverse effects, and was also associated with a 24% reduced risk of stroke

    (April 3, 2013 - Insidermedicine) From Japan - Baldness raises risk of coronary heart disease, according to a report published in BMJ Open. Researchers conducted a meta-analysis of 6 studies published between 1993 and 2008. The studies involved nearly 40,000 men. Results from three of the studies showed that men who lost most of their hair were 32% more likely to develop coronary heart disease when compared to those with a full head of hair. Results of the remaining three studies found that balding men were 70% more likely to have heart disease. This increased risk was not connected to receding hair lines, but rather, only if the balding occurred at the top/crown of the head.

    (April 3, 2013 - Insidermedicine) From Sweden - According to a report published in the Annals of Rheumatic Diseases, low testosterone levels in men may predict rheumatoid arthritis. Researchers studied over 33,000 men and women who were born between 1921 and 1949. Participants were followed for 30 years from 1974 to 2004. Researchers reviewed blood samples that were available for nearly 300 of the men, 100 of whom developed rheumatoid arthritis over the study period. After accounting for risk factors, researchers found that men with low testosterone levels were much more likely to develop rheumatoid arthritis.

    (April 3, 2013 - Insidermedicine) From Wisconsin - Age-related macular degeneration is the leading cause of vision loss in people over the age of 65, according to a report published in Ophthalmology. Researchers studied 5,000 individuals for 20 years, monitoring vision loss and eye disease in the patients. They found that, though there has been great progress in sight-saving drugs as well as in disease prevention, AMD is still the leading cause of vision loss in those over the age of 65. AMD causes severe vision loss in nearly 15% of all Americans over the age of 85.

    (April 2, 2013 - Insidermedicine) From Boston - Melatonin levels may be connected to type 2 diabetes, according to a report published in JAMA. Researchers compared 370 diabetic women to 370 controls, all of whom were taking part in a long term study. After accounting for risk factors such as BMI, family history, smoking, diet, and levels of exercise, researchers found that participants who had low levels of melatonin secretion during sleep were at 2x increased risk of type 2 diabetes

    Cholesterol linked to macular degeneration

    (April 2, 2013 - Insidermedicine) From St. Louis - A ...

    (April 2, 2013 - Insidermedicine) From St. Louis - A new report published in Cell Metabolism finds that cholesterol buildup that occurs during atherosclerosis may also cause macular degeneration. Researchers studied mice, examining the rodents 'macrophages' as they aged. Macrophages are immune cells that are responsible for removing cholesterol and fats from tissues in the body. As people age, cholesterol builds up and the macrophages malfunction, an aspect that can result in atherosclerosis and new blood vessel growth found in macular degeneration. Researchers found that the macrophages in old mice had low levels of a protein, known as ABCA1, that removes cholesterol from cells. When researchers gave the rodents a medication that restored levels of ABCA1, cholesterol was removed more effectively--and the development of new blood vessels was slowed.

    (April 1, 2013 - Insidermedicine)  From Toronto – Hockey causes over half of traumatic brain injuries among children in Canada who participate in organized sports, according to a report published in PLOS ONE. Researchers studied data from The Canadian Hospitals Injury Reporting and Prevention Program, examining nearly 13,000 children aged 5-19 who had suffered a sports related brain injury. The causes of the children’s injuries were categorized as ‘struck by player’, ‘struck by object’, ‘struck by sport implement’, ‘struck by playing surface’ or other. Results showed that 44% of the injuries occurred during hockey—with 70% of these injuries occurring as a result of player-to-player contact in children over 10.

    (April 1, 2013 - Insidermedicine) From North Carolina – The human immune system has an innate ability to destroy HIV—when a gene is removed from the virus, according to a report published in PLOS Pathogens. Researchers ‘humanized’ a mouse model—giving the rodents a human bone marrow, liver and thymus tissues, meaning the rodents had no immune system of their own and instead had a fully functioning human immune system. Researchers then infected the rodents with HIV. They found that, after removing the viral infectivity gene (vif) from HIV, a group of proteins in the human immune system could effectively mutate the virus and completely kill it

    (March 29, 2013 - Insidermedicine) From Minnesota – Scientists have discovered a new gene that raises risk of ovarian cancer, according to a report published in Nature Communications. For the study, an international group of researchers compared over 16,000 ovarian cancer patients to over 26,000 healthy controls. They found that variations in the HNF1B gene were more overrepresented in one subtype of ovarian cancer and underrepresented in another. They were also able to demonstrate that DNA methylation was associated with different  ovarian cancer subtypes
