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.

Iron deficiency causing sticky blood linked to stroke risk

(February 20, 2014 - Insidermedicine) From London - Iron deficiency may raise risk of stroke due to sticky blood, according to a report published in PLOS ONE. Researchers studied nearly 500 patients who had a condition known as pulmonary arteriovenous malformations--or, abnormal blood vessels in the lungs. Results showed that even those who had moderately low iron levels were at 2x increased risk of stroke when compared with those with normal iron levels.

Inactivity in older age linked risk of major disability

(February 20, 2014 - Insidermedicine) From Chicago - A new report published in the Journal of Physical Activity & Health finds that inactivity in old age is linked to risk of major disability. Researchers studied over 2,200 adults aged 60 and older from 2002-2005. Over this time period, participants wore an accelerometer to measure their activity levels. Results showed that every additional hour spent sitting doubled the risk of being disabled--regardless of the amount of moderate exercise undertaken.

Vitamin C may reduce risk of stroke

(February 19, 2014 - Insidermedicine) From France - Vitamin C may lower stroke risk, according to a report presented at the American Academy of Neurology's annual meeting. Researchers compared 65 individuals who had suffered in intracerebral hemorrhagic stroke to 65 healthy controls. Participants had their Vitamin C blood levels measured. Results showed that, on average, those who suffered a stroke had depleted levels of vitamin C, while the healthy controls had normal levels.

Do football helmets really protect against brain injury?

(February 19, 2014 - Insidermedicine) From Florida - A new report presented at the American Academy of Neurology's annual meeting finds that football helmets do little to protect against concussions. Researchers 10 popular football helmet designs, having a crash test dummy undergo simulated head and neck impact. Sensors measured the dummy's head reaction linear and rotational forces at 12 mile per hour impact. Results showed that the helmets, on average, only reduced risk of traumatic brain injury by around 20%--when compared to dummies not wearing a helmet

Exercise may help slow retinal degeneration

(February 14, 2014 - Insidermedicine) From Atlanta - Exercise may inhibit the progression of retinal degeneration, according to a report published in the Journal of Neuroscience. Researchers studied a mouse model, having the rodents exercise for an hour a day for five days a week for 2 weeks. All of the subjects were then exposed to a toxic bright light that simulates retinal degeneration, then continued their exercise routine for two more weeks. Other mice spent time the time on a stationary treadmill. Results showed that the rodents that exercised lost only half of the photoreceptor cells as the rodents who remained stationary.

Smoking raises risk of most common type of breast cancer

(February 14, 2014 - Insidermedicine) From Seattle - A new report published in Cancer finds that smoking raises risk of the most common kind of breast cancer. Researchers studied nearly 1,000 patients diagnosed with estrogen receptor positive breast cancer (the most common subtype of the disease), as well as nearly 200 with triple-negative breast cancer and over 900 cancer-free controls. Participants were between 20 and 44 years old. Results showed that women who were current or recent smokers who had smoked a pack a day for at least a decade were at 60% increased risk of developing estrogen receptor positive breast cancer.

Donating kidneys only results in small raised risk of kidney disease

(February 13, 2014 - Insidermedicine) From Baltimore - Kidney donations only result in a small increased risk of kidney disease, according to a report published in JAMA. Researchers reviewed data on nearly 100,000 kidney donors, as well as a group of 20,000 healthy controls taking part in a long term study. They found that though there was a small increased risk of end-stage renal disease among the donors when compared to healthy controls, the risk was still much lower than individuals in the general population.

Heading a ball in soccer may be linked to concussions

(February 10, 2014 - Insidermedicine) From Toronto - According to a report published in Brain Injury, more research is needed into the possible effects of heading the ball in soccer. Researchers conducted a meta-analysis on the effect of heading the ball had on the brain. They found that concussions accounted for as much as 8.6% of the total injuries suffered during soccer games. Interestingly, one study showed that nearly 63% of soccer players had symptoms of a concussion, but only one quarter had actually realized it. These results call into question the practice of repetitive heading during a game.

(February 10, 2014 - Insidermedicine) From North Carolina - Women have a worse quality of life following a stroke than men, according to a report published in Neurology. Researchers studied over 1,300 individuals between the ages of 56 and 77 years. All participants had had a stroke and had their quality of life measured at 3 months, and then 12 months post-stroke. Results showed that, even after taking into account factors such as the strokes severity, women fared worse following their stroke than men

More TVs and computers in the developing world linked to diabetes and obesity

(February 10, 2014 - Insidermedicine) From Vancouver - A new report published in the CMAJ finds that as more people in the developing world own TVs and computers, the higher the rates of obesity and type 2 diabetes. Researchers studied data on over 150,000 adults from over 100,000 households in 17 countries. Countries were divided into high income, upper-middle income, lower-middle income and low income. Participants were surveyed regarding their activity levels, diet and presence of diabetes, whether they had a TV, computer or care, and their height and weight was measured as well. Results showed that ownership of cars, computers and TVs was associated with higher rates of obesity and type diabetes in the lower income countries.
