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.

Vision loss linked to depression

(March 12, 2013 - Insidermedicine) From Alabama – Vision loss may cause depression in adults, according to a report published in JAMA Ophthalmology. Researchers studied over 10,000 US adults over the age of 20. Participants were followed for 3 years, measuring prevalence of depression, visual acuity and self-reported visual loss. After controlling for age and other risk factors, researchers found that self-reported vision loss, but not loss of visual acuity, was strongly associated with depression.

Sleep loss may be a sign of early Alzheimer's disease

(March 11, 2013 - Insidermedicine) From St. Louis – Sleep loss can be an early sign of Alzheimer’s disease, according to research published in JAMA Neurology. Researchers studied nearly 150 volunteers, aged 45-75 years old. All participants were cognitively normal at the outset of the study. Researchers analyzed participant’s spinal fluids for Alzheimer’s markers, while participants recorded their sleep habits for two weeks. Results showed that 32 participants had preclinical Alzheimer’s disease—and that these individuals had much worse sleep efficiency than individuals without the Alzheimer’s markers.

Do mouth guards and helmets actually prevent concussions?

(March 11, 2013 - Insidermedicine) From Switzerland – A new report published in the British Journal of Sports Medicine questions whether mouth guards and helmets actually prevent concussions. A team of international researchers conducted a meta-analysis to form the Consensus Statement on Concussion in Sport. Results showed that, though mouth guards and helmets can ward off some facial and head injuries, there is no evidence that they prevent concussion. Rather, wearing a helmet or mouthguard may actually encourage the athlete to take greater risks.

(March 11, 2013 - Insidermedicine) From the UK – Children in the UK are exposed to millions of tobacco images every week during prime time television, according to a new report published in Tobacco Control. Researchers analyzed five free-to-air TV channels, examining content broadcast between 6 and 10 pm on 3 separate occasions. Content was analyzed for use of a tobacco product, implied use, tobacco packs or ashtrays, or references to tobacco. Researchers also noted clear and ambiguous tobacco merchandising. At least one third of the programmes broadcast contained tobacco content. Two thirds of this tobacco content appeared before 9 pm. Using this data, researchers estimate that young people in the UK are exposed to 59 million instances of tobacco imagery every week, 16 million instances of actual tobacco use, and 3 million instances of branding/merchandising.

(March 8, 2013 - Insidermedicine)From Jamaica - Walking regularly after a stroke can greatly improve quality of life, according to a report published in Stroke. Researchers studied over 120 stroke survivors, randomizing participants to either brisk outdoor walking three times a week or to receive therapeutic massage with no supervised exercise. Results showed that individuals in the walking group reported 17% improvement in quality of life, were able to walk 18% farther in an endurance test, and had a significantly lower resting heart rate than those in the massage group.

(March 6, 2013 - Insidermedicine) From California - Glaucoma patients with faster binocular visual loss have worse quality of life, according to a report published in JAMA Ophthalmology. Researchers studied nearly 400 glaucoma patients taking part in two long-term studies. Participants were followed for a mean of 7 years, and had their integrated binocular visual field loss and vision-related quality of life measured during the study period. Results showed that ratres of BVF change were strongly associated with abnormalities in vision-related quality of life, even after accounting confounding variables.

(March 6, 2013 - Insidermedicine) From Norway - Insomnia raises risk of heart failure, according to a report published in the European Heart Journal. Researchers studied over 50,000 individuals between 20-89 years of age. Participants were followed for an average of 11 years. Results showed that three specific insomnia symptoms--trouble falling asleep, trouble staying asleep, and not waking up feeling refreshed--raised risk of developing heart failure threefold.

(March 6, 2013 - Insidermedicine) From Connecticut - A new report published in Nature finds that salt consumption may play a role in autoimmune diseases such as multiple sclerosis. Researchers studied the effects of high salt consumption in a mouse model. They found that putting salt into the diet of the rodents resulted in the production of a type of T cells that worsened the rodent's pathogenic immune system response, and are known to be associated with autoimmune diseases. Trials aimed at determining salt's effect on autoimmune diseases in humans are being planned.

(March 5, 2013 - Insidermedicine) From Wisconsin - A new report published in Ophthalmology finds a high incidence of visual impairment in elderly individuals. Researchers studied nearly 5,000 people ages 43-86 who were taking part in the Beaver Dam Eye Study. Participants underwent baseline visual examinations from 1988-1990, and had follow-up exams in 5 year intervals. Results showed a 15% incidence of visual impairment among individuals 85 and older. As well, the study found that age-related macular degeneration remained the leading cause of visual impairment throughout the 20 year study.

(March 4, 2013 - Insidermedicine) From Toronto - Canadians who smoke 'contraband' cigarettes are much less likely to quit smoking, according to a report published in CMAJ. Researchers studied a group of smokers for 6 months, some of whom smoked premium or discount cigarettes (prices ranging from $6.30--$10.30) while some smoked 'contraband' cigarettes--which cost only $2.50. Results showed that only 19% of contraband smokers tried to quit during the follow-up, compared to 30% of the other smokers. 11% of those smoking premium or discount cigarettes managed to quit smoking for 30 days, while only 4% of those smoking contraband cigarettes could do the same. Contraband cigarettes account for 42% of cigarette sales in Ontario.
