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.

(January 25, 2012 - Insidermedicine) From Oxford- Heart attack death rates in England have been dramatically reduced in the last 10 years, according to a report published in the BMJ. Studying over 860,000 heart attacks from 2002-2010, researchers noted a 50% decline in heart attack deaths among men and a 53% decline among women. From London - A new report published in PLoS ONE finds that people who work too much are at raised risk of depression. Studying 2000 civil servants, researchers found that individuals who worked 11 or more hours a day had a twofold increased risk of suffering a major depressive episode. And finally, from Chicago - Doctors may be giving patients a false sense of security regarding their heart attack risk, according to a report published in the NEJM. In a study of over 250,000 people, researchers reviewed the effectiveness of providing patients with a prediction of their 10 year risk for heart attack. They found that the short-term risk prediction is misleading and provides patients with a false sense of security, since having just one risk factor for heart attack, such as high blood pressure or cholesterol, greatly increases one's lifetime risk of heart attack.

(January 23, 2012 - Insidermedicine) From California - Keeping your brain active may reduce risk of Alzheimer's disease, according to a report published in the Archives of Neurology. Researchers studied 65 healthy elderly patients, as well as 10 Alzheimer disease patients and 11 young controls. They found that individuals who participated in more brain stimulating activities throughout their life, particularly in their early and middle years, had reduced levels of β-amyloid protein--a major component of AD development. From Germany - Two reports published in the Journal of Experimental Medicine find a single protein that may be key to fighting several forms of cancer. In the first study, researchers found that inhibiting the protein HSP90 slowed breast tumour growth in a mouse model, while the second study revealed that HSP90 inhibitors also slowed the growth of leukaemia cells in a mouse model. And finally, from Boston - Research published in CANCER finds that many patients continue to smoke even after being diagnosed with cancer. Examining nearly 5,500 colorectal and lung cancer patients, researchers found that a substantial minority of these patients continued smoking 5 months after their diagnosis.

(January 22, 2012 - Insidermedicine) From New York - Statins may have cancer fighting ability, according to a report published in Cell. Scientists examined cancer cells in an artificial model of the human breast, finding that mutations in the tumour suppressing gene p53 led to disorganized and invasive growth of the cancer cells. When the p53 mutation was treated with statins, researchers saw the cancer cells stop their invasive growth and even die. From British Columbia - 10% of Canadians cannot afford prescription drugs, according to a report published in the CMAJ. Researchers surveyed nearly 6,000 Canadians, finding that 1 in 10 participants reported not taking prescription drugs as directed due to cost. From Georgia - Melanoma death rates are dropping, but only among those with the most education, according to a report published in the Archives of Dermatology. Studying death certificates from 26 American states, researchers found that melanoma death rates dropped by 10% from 1997 to 2007. The researchers noted, however, that these rates declined only in individuals who had at least 13 years of education.

(January 21, 2012 - Insidermedicine) From Maryland - Obesity rates in the US are still high and have not changed much in recent years, according to a report published in JAMA. Analyzing data from a nationally representative sample, researchers found that one in three adults and one in six children and teens are obese, while there have been increases in obesity rates among certain demographics. From Texas - A new report published in Science Translational Medicine describes how cigarette smoke causes emphysema. Studying mice, researchers found that toxic cigarette smoke activates a host of genes in the immune system that in turn inflame the lungs, resulting in emphysema. And finally, from Quebec - A new report published in the Lancet emphasizes the importance of diagnosing and treating insomnia early. Researchers reviewed evidence regarding the sleep disorder, finding that insomnia patients are over 5x more likely to have anxiety and depression, 2x more likely to develop congestive heart failure and diabetes, and 7x more likely to develop substance abuse problems

(January 20, 2012 - Insidermedicine) From Boston - PCE in the drinking water significantly raises risk of mental illness, according to a report published in Environmental Health. Researchers followed children born between 1969 n 1983--a time in which water pipes were known to be leaking PCE, a chemical used to dry-clean clothes, into drinking water supply. They found that prenatal and early childhood exposure to the solvent resulted in a 2x increased risk of bipolar disorder and 50% increased risk of PTSD. From Maine - A new report published in Cell identifies a possible cause of neurodegeneration. Researchers noted a mutation in 1 copy of the U2 snRNA gene that caused neurodegeneration in a mouse model. And finally, from Georgia - Exercise helps ease anxiety in women, according to a report published in Psychotherapy and Psychosomatics. Researchers assigned 30 sedentary women suffering from generalized anxiety disorder to either an aerobic exercise group or a control group. They found that the exercise group experienced significant reductions in their worry symptoms, as well as moderate reductions in their irritability, tension and pain.

(January 19, 2012 - Insidermedicine) From New York - Statins may have cancer fighting ability, according to a report published in Cell. Scientists examined cancer cells in an artificial model of the human breast, finding that mutations in the tumour suppressing gene p53 led to disorganized and invasive growth of the cancer cells. When the p53 mutation was treated with statins, researchers saw the cancer cells stop their invasive growth and even die. From Boston - Levels of a certain blood protein can predict which diabetic patients will develop kidney disease, according to a report published in Journal of the American Society Nephrology. Studying over 1,000 type 1 and 2 diabetic patients, researchers found that high levels of TNF receptor in the blood increased risk of kidney disease later in life by 3-5x. And finally, from Quebec - A new report published in the Lancet emphasizes the importance of diagnosing and treating insomnia early. Researchers reviewed evidence regarding the sleep disorder, finding that insomnia patients are over 5x more likely to have anxiety and depression, 2x more likely to develop congestive heart failure and diabetes, and 7x more likely to develop substance abuse problems
