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.

Too much TV significantly lowers sperm count

(February 8, 2013 - Insidermedicine) From Boston – Too much TV may significantly reduce a man’s sperm count, according to a report published in the British Journal of Sports Medicine. Researchers studied nearly 200 men between 18-22 years old. Participants were asked about their levels of physical activity and TV-watching habits, as well as other factors such as diet, smoking and levels of stress. Results of semen analysis revealed that men who watched over 20 hours of TV a week had a 44% lower sperm count than men who watched almost no TV at all. In contrast, men who exercised for 15 or more hours a week had a 73% higher sperm count than men who exercised less than 5 hours a week.

(February 8, 2013 - Insidermedicine) From London – Stress at work does not raise risk of cancer, according to a report published in the BMJ. Researchers conducted a meta-analysis of 12 studies comprised of 116,000 participants aged 17-70. Participant’s psychological stress at work was assessed using job strain. Results showed that 5% of participants developed cancer over an average of 12 years follow-up. There was no connection between elevated job strain and risk cancer.

Patching recommendations for amblyopia not being followed in clinics
(February 7, 2013 - Insidermedicine) From Toronto – A new ...
(February 7, 2013 - Insidermedicine) From Toronto – A new report published in Ophthalmology examines whether evidence-based patching recommendations from are being implemented in clinical practice. Researchers studied over 120 children with amblyopia who were seen by both academic and community ophthalmologists, examining whether recommendations from the Pediatric Eye Disease Investigator Group (PEDIG) were being implemented. Results showed that children with moderate amblyopia were prescribed patching for a mean of 3.2 hours a day, though recommendations indicate only 2 hours of daily treatment. Children with severe amblyopia were prescribed a mean of only 3.9 hours a day, though recommended treatment is 6 hours a day. Amblyopic eye acuity during follow-up for both groups was reduced when compared children who took part in PEDIG.

Southern diet, heavy on fried foods and salt, strongly linked to stroke

(February 7, 2013 - Insidermedicine) From Alabama – A ‘Southern’ diet raises risk of stroke, according to a report presented at the ASA’s International Stroke Conference. Researchers studied over 20,000 US men and women with a minimum age of 45. Participants were enrolled from 48 states and were followed every six months for several years. Results showed that individuals who ate a Southern diet—heavy on fried foods, organ meats, salt and sugar—6 days a week were 41% more likely to suffer a stroke when compared to those who ate a Southern diet 1 time a week. The Southern diet accounted for 63% of elevated stroke risk among African Americans. Individuals who ate a diet high fruits, vegetables, legumes, and whole grains, were at 29% reduced risk of stroke.

(February 6, 2013 - Insidermedicine) From New Zealand - Marijuana may raise risk of stroke in young adults, according to a report presented at the American Stroke Association's International Stroke Conference. Researchers examined 160 stroke patients between the ages of 18 and 55. All participants had a urine test upon admission to the hospital. When compared to matched controls, researchers found that these stroke patients were 2.3x more likely to test positive for cannabis in their urine tests.

Air pollutant may be causing 1 in 20 preeclampsia cases

(February 6, 2013 - Insidermedicine) From Sweden - According to a study published in BMJ Open, an air pollutant may be responsible for a significant amount of preeclampsia cases. Researchers studied over 120,000 births in Sweden between 1998-2006. They also reviewed mothers exposure to the air pollutants ozone and vehicle exhaust (nitrogen oxide), as well as their asthma status. Results showed no association between preeclampsia and vehicle exhaust, as well as no association between air pollutants and children underweight at birth. However, researchers did find that exposure to ozone in the first three months of pregnancy raised risk of preeclampsia and premature birth. Researchers estimate that ozone exposure may account for 1 in 20 cases of preeclampsia.

(February 6, 2013 - Insidermedicine) From Chicago - The number of Alzheimer's patients could triple by 2050, according to a report published in Neurology. Researchers studied nearly 11,000 Caucasian and African-American individuals aged 65 and older. Participants were followed between 1993-2011 and were assessed every three years for the presence of dementia. Researchers also examined data on death rates, education and future population estimates from the US Census Bureau. Results showed that nearly 14 million people are expected to have Alzheimer's disease by 2050, a threefold increase from the 4.7 million individuals affected in 2010.

(February 5, 2013 - Insidermedicine) From Germany - A new report published in the British Journal of Ophthalmology finds a genetic mutation that may predict bilateral disease in retinoblastoma patients. The study involved more than 500 children with unilateral retinoblastoma, 15 of whom went on to develop metachronous bilateral retinoblastma. Results showed that nearly 23% of those who had the RB1 genetic mutation went on to develop bilateral disease, while all 155 children proven to not have the mutation remained affected in only one eye.

(February 5, 2013 - Insidermedicine) From London - According to a report published in PLOS Medicine, obesity may cause vitamin D deficiency. Researchers examined the genetic data of nearly 42,000 adults, comparing their results to an additional 123,000 participants. Genetic markers were analyzed to explore the link between BMI and genes associated with vitamin D metabolism. Results showed that a 10% increase in BMI was linked to a 4% reduction in vitamin D concentrations. These results were consistent regardless of gender and age.

(February 5, 2013 - Insidermedicine) From California - Mammography screening every two years is as effective as yearly screening for older women, according to a report published in the Journal of the National Cancer Institute. Researchers reviewed data on over 140,000 women between 66 and 89 years of age. Nearly 3,000 of the women had breast cancer. They found no difference in the rates of advanced breast cancer among women screened annually or biennially. Nearly 50% of women aged 66-74 who were screened annually had false positives, whereas only 29% of women screened biennially had false positives.
