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.

(November 29, 2012 - Insidermedicine) From Maryland - A new report released by the National Eye Institute (NEI) finds that the immune system may play a major role in age-related macular degeneration (AMD). Researchers studied 3 pairs of twins where only one sibling had AMD. Two the pairs of twins were fraternal and one was identical. Results showed that DNA methylation patterns--a process that regulates gene expression and can be influenced by environmental factors--were much more altered in twins with AMD than those without the condition

(November 28, 2012 - Insidermedicine) From Scotland - Newborns whose testes do not descend are at raised risk of testicular cancer, according to a report published in the Archives of Disease in Childhood. Researchers conducted a meta-analysis of 12 studies covering over 2 million boys that were followed for nearly 60 million person years. They found that boys whose testes did not descend at birth--a condition known as cryptorchidism--were nearly 3x more likely to develop testicular cancer.

(November 28, 2012 - Insidermedicine) From California - A compound found in rosemary may have some protective effects against macular degeneration, according to a report published in Investigative Ophthalmology & Visual Science. Researchers exposed retinal cells to oxidative stress--a major contributing factor to macular degeneration--and found that cells treated with the compound carsonic acid lowered levels of harmful free radicals and peroxides. They then treated a rodent model with the compound prior to inducing retinal damage. Results showed that carsonic acid protected the rodent's photoreceptors--a component of the eye that is essential for vision and damaged in macular degeneration.

Is it possible to predict risk of childhood obesity at birth?
(November 28, 2012 - Insidermedicine) From Finland - A new ...
(November 28, 2012 - Insidermedicine) From Finland - A new report published in PLOS ONE finds that it may be possible to predict risk of childhood obesity at birth. Researchers used data from a study following 4000 children born in 1986, predicting the child's risk of obesity with two methods. First, they used genetic profiling and found that genetic variants were not able to make an accurate prediction. Then, the researchers used a formula that accounted for: -The child's birth weight -BMI of the parents -Number of people in the household -The mother's professional status -Smoking status during pregnancy Using this formula, researchers found that the 20% of the children who were predicted to have the highest weight at birth accounted for 80% of the children who became obese. The formula was then tested out on study cohorts from Italy and the US and again proved accurate.

(November 27, 2012 - Insidermedicine) From Kentucky - A drug used to treat heart disease increases risk of death in atrial fibrillation patients, according to a report published in the European Heart Journal. Researchers reviewed data on over 4,000 atrial fibrillation patients who were enrolled in a long-term trial. They found that use of the drug digoxin raised risk of all-cause death by 41%, risk of death from cardiovascular causes by 35% and risk of death from heart arrhythmias by 61%. These results were independent of other risk factors and the presence of heart failure.

(November 27, 2012 - Insidermedicine) From Washington DC - A new report published in the Lancet finds that better physical fitness in combination with statins greatly improves survival in adults with high fat and cholesterol levels. Researchers reviewed medical records of over 10,000 men and women with dyslipidaemia (abnormal levels of bad fats and cholesterol), following participants for a median of 10 years. They found that death rates were lowest for those who were physically fit and were taking statins. The more fit the individual was, the lower their risk of dying during the study period. Adults who were the most physically fit and who were not taking statins were at 60-70% reduced risk of death.

(November 27, 2012 - Insidermedicine) From Michigan - Double mastectomies are unnecessary in most women who receive the operation, according to a report presented at the American Society of Clinical Oncology's Quality Care Symposium. Researchers followed nearly 1,500 breast cancer patients who had received treatment for their disease but had not had a recurrence. Nearly 1 in 5 participants who had a mastectomy had a double mastectomy. 90% of these women had reported being very concerned about the cancer returning. However, around 70% of these women were at very low risk of the cancer developing in the healthy breast.

(November 26, 2012 - Insidermedicine) From Thailand - Soothing sounds during eye surgery can help ease patient's anxiety, according to a report presented at the annual meeting of the American Academy of Ophthalmology. Researchers studied over 140 cataract patients divided into 3 groups. One group listened to soothing music during their operation, one listened to a combination of binaural beat audio therapy, soothing music and nature sounds, while the final group listened only to normal sounds that occur during surgery. Results showed that those who listened to the combined sounds experienced less anxiety during the operation and afterwards, as well as a slower heart rate and lower systolic blood pressure.

(November 26, 2012 - Insidermedicine) From Ohio - Injuries from inflatable bouncers have risen dramatically in recent years, according to a report published in Pediatrics. Researchers examined US emergency room data from 1995-2010, analyzing rates of childhood injuries attributed to inflatable bouncers. They found a 15-fold increase in the amount of injuries over the time period. In 2010, over 30 children a day were treated for injuries due to the bouncers, equivalent to one child every 45 minutes. Nearly 20% of all of these injuries were to the head and neck, demonstrating the potential serious risk that these bouncers pose.

(November 26, 2012 - Insidermedicine) From Toronto - A new report published in the CMAJ finds that warfarin therapy may cause more hemorrhages than previously thought. Researchers studied over 125,000 atrial fibrillation patients aged 66 and older. All patients were taking warfarin for their heart condition, and were followed for 13 years. Results showed that the overall risk of hemorrhage was nearly 4% per person-year, and nearly 12% within the first month of starting therapy. Previous trials reported hemorrhage rates to be between 1%-3% per person-year.
