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.

(December 7, 2012 - Insidermedicine) From Baltimore - A new report published in Epilepsy Research finds that fasting may reduce seizures in children with drug resistant epilepsy. Researchers studied six children from 2-7 years old, who were currently on the ketogenic diet--a high-fat, low carbohydrate diet that has been shown to reduce seizures. Participants in the study had not seen their seizures improve on the diet alone. Researchers then had the children fast on alternate days during the week while remaining on the diet. Results showed that four of the children experienced a 50-99% reduction in their seizures after fasting.

(December 6, 2012 - Insidermedicine) From New York - A new prenatal test may soon become the standard of care, according to two reports published in the New England Journal of Medicine. In the first study, researchers followed 4,400 patients from nearly 30 centres across the US. All participants were women with advancing age whose fetuses had been shown in screening to be at raised risk of Down syndrome or have other abnormalities. They found that the new test, known as chromosomal microarray, performed as well as karotyping in identifying an abnormal number chromosomes, and also identified more abnormalities than were seen with karotyping. In the second study, researchers used the same test to analyze stillbirth. They found that microarray returned a clinically relevant results in 87% of over 500 cases studied. Karotyping used to analyze stillbirth typically fails to return inforamation in 25% of cases.

(December 6, 2012 - Insidermedicine) From Oxford - Extending tamoxifen therapy can reduce risk of breast cancer recurrence, according to a report published in the Lancet. Researchers randomized nearly 7,000 breast cancer patients to either stop taking tamoxifen after 5 years of treatment or to continue taking the drug for 5 more years. Results showed that women who continued to take tamoxifen were less likely to have their cancer recur and die. Overall, there was a nearly 3% reduction in breast cancer mortality during the study period.

Visual field changes connected to declining health in retinitis pigmentosa patients

(December 6, 2012 - Insidermedicine) From Baltimore - A new report published in the British Journal of Ophthalmology finds that worse than normal visual field scores in retinitis pigmentosa patients may reflect declining general health. Researchers studied nearly 40 RP patients , measuring their visual acuity, contrast sensitivity and visual fields 2x a week for 2-3 months. Prior to each test, participants were asked to report their general health. Results showed no association between reduced general health and psychological health and lower than normal scores on visual acuity and contrast sensitivity tests. However, participants who reported decreased general health were much more likely to have lower than normal scores on visual field tests.

(December 5, 2012 - Insidermedicine) From Oxford - According to research published in Human Reproduction, children who are born after infertility treatment are at raised risk of asthma. Researchers studied a cohort of nearly 20,000 children, following 13,000 of the children until the age of 5. They found that children who were born to sub-fertile parent--those that either had to wait a a year before conceiving or who needed infertility treatment--were 39% more likely to experience asthma at the age of 5, as well as 27% more likely to wheeze and 2x more likely to be taking asthma medication. Specifically, researchers found that children born after assisted reproduction technology, primarily in vitro fertilization and intracytoplasmic sperm injection, were at 2.5x increased risk of asthma at age 5, as well as a 2x increased risk of wheezing and 4x increased risk of taking asthma medicate on.

(December 5, 2012 - Insidermedicine) From London - A commonly used sleeping pill raises risk of fatal pneumonia, according to a report published in Thorax. Researchers compared nearly 5,000 pneumonia patients to nearly 30,000 controls. Pneumonia patients were more likely than controls to have had pneumonia before, as well as several other illness, including heart attack, depression and mental illnesses. Researchers assessed use of two sleeping pills, zopiclone and benzodiazepine, in both groups. After taking into account the other illnesses and smoking status, researchers found that use of benzodiazepines were associated with a 54% increased risk of pneumonia. Participants taking benzodiazepines were also at 22% increased risk of dying within 30 days of contracting the infection, and 34% increased risk of dying within 3 years.

(December 5, 2012 - Insidermedicine) From Denmark - Childless women are at raised risk of early death, according to a report published in the Journal of Epidemiology and Community Health. Researchers reviewed data from several population registries over a 14 year period. They found that childless women were 4x more likely to die early from circulatory disease, cancer, and accidents than women who had given birth to their own child. Women who adopted a child had 50% lower death rates. Mental illnesses were also 50% lower in parents who adopted kids when compared to other parents.

(December 4, 2012 - Insidermedicine) From Pennsylvania - Power naps significantly reduce fatigue in residents working overnight shifts, according to a report published in the Journal of the American Medical Association. In the study, over 100 residents were randomized to a standard intern shift of 30 hours overnight, or to have power naps. These naps lasted 5 hours and were protected, meaning the resident would hand over their work phone to another resident and would not be disturbed. Adherence to the program was nearly 100%. Those who took protected naps increased the amount of time they slept by 50%, had much less periods of no-sleep while on call, and also had improved alertness.

(December 4, 2012 - Insidermedicine) From Birmingham - A person's risk of skin cancer includes more than just sun exposure, according to a report published in Genetics. Researchers examined genetic data on over 5,000 individuals taking part in a long-term study. Several predictive models were used to assess a person's risk of skin cancer, and the accuracy of each model was compared. Results showed that the predictive model that was the most accurate was one that accounted for standard risk factors, such as sex, as well as predicitve risk factors such as family history, ethnicity, UV exposure and genetic markers.

(December 4, 2012 - Insidermedicine) From the UK - A new report presented at the Resveratrol 2012 conference provides more evidence on red wine's cancer fighting properties. Scientists from the University of Leicester have been studying how resveratrol--a compound that exists in the skin of red grapes--fights cancer. Using laboratory experiments, the researchers found that a daily amount of resveratrol equivalent to two glasses of wine reduced the rate of bowel tumours in half. These promising results have yet to be confirmed in humans, however.
