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.

Reducing dietary sugar levels can be key to fighting obesity epidemic

(January 18, 2013 - Insidermedicine) From New Zealand – Reducing levels of sugar in the diet can greatly impact body weight, according to a report published in the BMJ. Researchers conducted a meta-analysis covering 71 studies regarding sugar intake and body weight. They found that advice to reduce sugar intake resulted in a .8 kg reduction in body weight over an 8 month period, while advice to increase sugar intake resulted in a .75 kg increase in weight. Though the numbers are small, the researchers believe that this parallel effect indicates that sugar intake reduction can play a major part in addressing the obesity epidemic.

(January 18, 2013 - Insidermedicine) From Minnesota – A new report published in the Annals of Allergy, Asthma and Immunology finds that low birth weight is not associated with risk of asthma. Researchers studied nearly 4,000 children born with a normal birth weight, as well as nearly 200 children with a low birth weight. All of the children were born between 1976 and 1979. Results showed that 6.7% of children with a low birth weight developed asthma, and that 5.4% of the children of a normal birth weight developed asthma—a difference that is not statistically significant.

(January 17, 2013 - Insidermedicine) From Atlanta - Cancer mortality has dropped significantly since 1991, according to the American Cancer Society's Annual Cancer Statistics published in CA: A Cancer Journal for Clinicians. Researchers examined data on cancer incidence, mortality and survival in the US from 1991--a year in which cancer death rates peaked--to 2009. Results showed that overall cancer death rates dropped by 20% over that time period, or approximately 1.2 million deaths. The study also predicts that over 1.6 million new cancer cases will be diagnosed and over 580,000 people will die from cancer in 2013. Prostate, lung and colorectal cancers will account for nearly half of all new cases in men, while breast, lung, and colorectal will account for about half of all new cases in women.

(January 17, 2013 - Insidermedicine) From India - Fluoroquinolones may be associated with worse outcomes from keratitis, according to a report published in JAMA Ophthalmology. Researchers conducted a randomized, double-masked placebo controlled trial on nearly 500 cases of keratitis. Participants were given moxifloxacin hydrochloride. Results showed that those who reported use of fluroquinolones at presentation had a 2x higher minimum inhibitory concentration than those who did not report fluoroquinolone use. These results indicate that use of fluoroquinolones may predict antibiotic resistance.

(January 16, 2013 - Insidermedicine) From Pittsburgh – Smartphone apps that claim to diagnose melanoma are not reliable, according to a report published in JAMA Dermatology. Researchers studied 4 smartphone applications that evaluated nearly 200 images of skin lesions for the presence of cancer. Apps were taken from the two most popular platforms. Results showed that 75% of the applications incorrectly diagnosed 30% or more melanomas as cancer-free.

(January 16, 2013 - Insidermedicine) From Texas – NFL players are at raised risk of depression as they age, according to a report presented at the AAN’s annual meeting. Researchers compared 34 retired NFL players with a history of concussion to 29 matched controls with no such history. Participants underwent tests measuring their thinking skills, mood and symptoms of depression. Results showed that the retired athletes scored much higher than minimal range for depressive symptoms than did controls

(January 15, 2013 - Insidermedicine) From France – Women who suffer migraines with aura may be at raised risk of heart attack and blood clots, according to a report to be presented at the annual meeting of the American Academy of Neurology. Researchers studied over 27,000 women for 15-years. Over 1,400 of the women suffered migraine with aura. Results showed that, after high blood pressure, migraine with aura was the second strongest contributor to heart attacks and strokes—ranking ahead of diabetes, smoking, obesity and family history of heart disease. We spoke with Dr. Tobias Kurth, MD, principal investigator of this study, who offered some further insight.

(January 15, 2013 - Insidemredicine) From Toronto – Cow’s milk and supplements are the biggest determinants in a child’s vitamin D levels, according to a report published in JAMA Pediatrics. Researchers studied blood samples from nearly 2,000 children under 6 years of age. The children were all part of a study in which they were tracked from birth. Results showed that the two factors that were most strongly associated with vitamin D levels were the use of daily supplements and drinking at least two cups of cow’s milk a day. Both of these factors played a bigger role than sun exposure and skin color. We spoke with Dr. Jonathon Maguire, MD, principal investigator of this study, who offered some further insight.

(January 13, 2013 - Insidermedicine Week in Review) From California - Researchers have found a way to determine which infants are at highest risk of death from whooping cough, according to a report published in the Journal of Pediatric Infections Diseases Society. Researchers retrospectively examined medical records of 31 pertussis patients from 5 intensive different intensive care units. They found that infants who had more severe disease had higher white blood cell counts--at least a 50% increase--than infants without severe disease. As such, researchers believe that taking early and repeated WBC counts can help determine the severity of the infant's infection. From Baltimore – Scientists have developed a new test for ovarian and endometrial cancers, according to a report published in Science Translational Medicine. The test, known as PapGene, examines 12 of the most frequently mutated genes in both cancers by using cervical fluid obtained during a routine Pap test. Researchers used PapGene on a group ovarian and endometrial cancer patients as well as healthy controls and found that the test was able to detect early and late-stage disease, and did not misdiagnose any of the healthy women.

BPA exposure has adverse effects on kidney and heart; Saliva gland test helps diagnose Parkinson's
(January 12, 2013 - Insidermedicine Week In Review) From New ...
(January 12, 2013 - Insidermedicine Week In Review) From New York – BPA exposure may adversely affect the kidneys and the heart, according to a report published in Kidney International. Researchers reviewed data on over 700 children aged 6-19, examining urine concentrations of BPA. Children who had the highest amount of BPA in their urine had an elevated albumin to creatinine ratio—a marker of renal impairment that also raises risk of heart disease. These results were consistent even after researchers accounted for risk factors such as smoke exposure, high blood pressure and weight. From Arizona– A new report presented at the annual meeting for the American Academy of Neurology finds that a saliva gland test may be able to diagnose Parkinson’s disease. Researchers examined two saliva glands for the presence of an abnormal Parkison’s protein in 15 Parkinson’s patients who had the disease for an average of 12 years. They found the protein in samples of 82% of the participants—suggesting the technique may be useful as a possible diagnostic tool.
