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 13, 2012 - Insidermedicine) From Australia - A new report published in the Journal of Neuroscience finds that preterm birth may affect memory and learning in teenage years. Researchers studied a group of teens who were born preterm or at-term, as well as a group of at-term adults. Non-invasive testing was conducted to measure the brain's plasticity--how responsive the brain is to stimulation. Results showed that teens who were born preterm had highly reduced plasticity, an aspect that can greatly affect memory and learning.

(November 13, 2012 - Insidermedicine) From the UK - Cancer patients can improve their fatigue with aerobic exercise, according to a report published in the Cochrane Library. Researchers conducted a meta-analysis on 28 studies examining cancer-related fatigue and exercise, updating a previous systemic review from 2008. All told, the review covered 56 studies and over 4,000 cancer patients, half of whom had breast cancer. Results showed that people with solid tumours could relieve their fatigue with aerobic exercise, including walking and cycling. Other forms of exercise however, did not have a significant impact on fatigue.

(November 13, 2012 - Insidermedicine) From Wisconsin - Meditation can reduce risk of heart attack, stroke and death in African Americans with heart disease, according to a report published in Circulation: Cardiovascular Quality and Outcomes. Researchers randomized 200 clinically obese African Americans suffering from heart disease to take part in a transcendental meditation program or a health education program about lifestyle modification. After 5 years followup, researchers found that individuals in the meditation group were nearly 50% less likely to suffer a heart attack, stroke or die than those in the health education group.

(November 12, 2012 - Insidermedicine) From Sweden - Dancing may improve health in girls with internalizing problems, according to a report published in the Archives of Pediatrics and Adolescent Medicine. Researchers studied over 100 teenage girls with psychosomatic symptoms--including pain in the head, stomach or neck, back/shoulder and persistent feelings of tiredness, worry, or stress. Study participants were randomized into an intervention group--taking part in a dance program twice a week for eight months--or into a control group. Results showed that girls who took part in the dance program had much better self-reported health than those who did not take part in the program. This positive effect remained up to 8 months after the intervention ended. 91% of the girls in the dance program said that the program was a positive experience.

(November 12, 2012 - Insidermedicine) From Denmark - Pregnant women who get the flu may be more likely to give birth to a child with autism, according to a repot published in Pediatrics. Researchers examined nearly 100,000 children between 8 and 14 years old who were born between 1997 and 2003. Their mothers were interviewed in order to ascertain any infections or high fevers they suffered during pregnancy. Researchers found that mothers who had the flu while pregnant were 2x more likely to have a child with autism. Those who had a fever for a week or more prior to their third trimester were 3x more likely to have a child with autism. The researchers warn, however, that their study was exploratory and does not definitely link the infection to autism spectrum disorder

(November 12, 2012 - Insidermedicine) From California - A new report published in Neurology finds that people who have had pesticide exposure and also suffer a head injury are at significant increased risk of Parkinson's disease. Researchers studied over 1,000 individuals from an agricultural area in California, nearly 400 of whom had Parkinson's disease. Participant's exposure to the pesticide paraquat--a weed killer--was determined using geographic data. Participants also reported if they ever had a head injury where they lost consciousness for 5 minutes or more. Results showed that Parkinson's patients were 2x more likely to have suffered a head injury that caused 5 minutes loss of consciousness. They were also 36% more likely to have exposure to paraquat than those without the disease. Taken together, suffering a head injury and being exposed to the pesticide resulted in a 3x increased risk of Parkinson's disease

Common signs of aging may indicate heart disease; Children consume as many as 300 extra calories a day if they eat out
(November 11, 2012 - Insidermedicine Week in Review) From Denmark ...
(November 11, 2012 - Insidermedicine Week in Review) From Denmark - Several signs of aging may be an indicator of heart disease, according to research presented at the AHA's Scientific Sessions. Researchers reviewed data on nearly 11,000 individuals over the age of 40 from the Copenhagen Heart Study. During the 35 years of follow-up, over 3,400 individuals developed heart disease and 1,700 had a heart attack. Analysis revealed that those who had 3-4 aging signs--receding hairline at the temples, fatty deposits around the eyelid, earlobe crease, or baldness at the crown--were at 57% increased risk of suffering a heart attack and 39% increased risk of heart disease. This increased risk was independent of traditional risk factors. From Chicago - Children consume more calories when they eat at either a fast food or full service restaurant, according to a report published in the Archives of Pediatrics and Adolescent Medicine. Researchers studied over 10,000 children and adolescents, comparing their calorie intake, diet and sugar-sweetened beverage consumption on days they ate at home, and fast food or full service restaurants. They found the following: ? ? -When adolescents ate fast food, they consumed an additional 309 calories a day? -When children ate fast food, they consumed an additional 126 calories? -When adolescents ate at a full service restaurant, they consumed an extra 267 calories -When children ate at a full service restaurant, they consumed an extra 160 calories?? These numbers, the authors point out, are especially concerning because 41% of adolescents and 1/3 of children consume fast food on a given day.

(November 10, 2012 - Insidermedicine Week in Review) From Boston - Daily multivitamins do not reduce risk of heart attack and stroke in men, according to a report published in JAMA. Researchers followed nearly 15,000 male physicians, over 700 of whom had a history of heart disease at the outset of the study. Participants were randomized to receive either daily multivitamins or placebo for a median follow-up of 11 years. Nearly 1,800 men suffered a cardiovascular event during the follow-up period, and over 800 died from cardiovascular causes. Analysis revealed that men taking multivitamins were no less likely to die from cardiovascular causes than men taking placebo. Though there were fewer deaths overall in the multivitamin group, the difference was not statistically significant. From Boston - A new report published in PLOS Medicine finds that physical activity can add up to 7 years to life expectancy. Researchers conducted a meta-analysis of 6 prospective cohort studies that comprised over 650,000 individuals. During follow-up, which lasted an average 10 years, there were over 82,000 deaths. Results showed that participation in low levels of moderate to vigorous physical activity--equivalent to 75 minutes of brisk walking a week--reduced risk of death by 19% and approximately a 1.8 year gain in life expectancy. Those who did equivalent to 150 minutes of brisk walking gained 3.4 years of life. Brisk walking for 450 minutes a week resulted in an additional 4.5 years to life expectancy. These gains were made regardless of race, gender and BMI.

(November 9, 2012 - Insidermedicine) From California - Breast cancer patients might fare better vs. their disease depending on the quality of their personal relationships, according to a report published in Breast Cancer Research and Treatment. Researchers followed over 2,200 women diagnosed with with early stage breast cancer for an average of 11 years, categorizing patients as either socially isolated, moderately integrated, or socially integrated. Results showed that women who were socially isolated had a 34% increased risk of dying from their disease when compared to those who were socially integrated. In addition, women with small networks of friends and low levels of support were at 61% increased risk of death when compared to women who had small networks of friends but high levels of support. These results indicate that the quality--and not simply quantity--of personal relationships plays a role in breast cancer survival.

(November 9, 2012 - Insidermedicine) From California - Research presented at the American Society of Human Genetics meeting identifies a strong link between telomere length and death. Researchers from Kaiser Permanente and UCSF studied over 100,000 individuals of multiple ethnicities with an average age of 63, examining participant's medical records as well as their demographic and behavioural factors. Saliva samples were collected and genotyped for the analysis of telomeres--stretches of DNA that shield the ends of chromosomes. Dr. Catherine Schaefer, lead author of the study, found that "shorter-than-average telomeres were prospectively associated with mortality, [however] only those with the shortest telomeres were at increased risk of death."
