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.

Socioeconomic status tied to risk of peanut allergy

(November 9, 2012 - Insidermedicine) From California - High socioeconomic status has been linked to increased risk of peanut allergy, according to a report presented at the ACAAI annual scientific meeting. Researchers examined over 8,000 patients, nearly 800 of whom had a higher antibody level to peanuts. They found that higher rates of peanut allergies were found in families with higher socioeconomic status. These results reinforce the 'hygiene hypothesis' that maintains that over-sanitation and lack of exposure to germs may actually prevent the immune system from developing normally

(November 8, 2012 - Insidermedicine) From Sweden - Bipolar women are much more likely to have pregnancy and birth complications, according to a report published in the British Medical Journal. Researchers compared over 800 pregnant women with bipolar disorder to over 300,000 without the condition who were giving birth between 2005 and 2009. 320 of the bipolar patients were treated for their condition, while the remainder were untreated. Results showed that both treated and untreated mothers were more likely to have a c-section, instrumental delivery, and were also at a 50% increased risk of preterm birth. As well, bipolar women were at raised risk of giving birth to a baby with a small head and one with episodes of low blood sugar levels.

New technique can predict how cancer patients will respond to chemotherapy

(November 7, 2012 - Insidermedicine) From the Netherlands - A new report presented at the Symposium on Molecular Targets and Cancer Therapeutics describes a novel, non-invasive method that can predict how a patient will respond to chemotherapy. Researchers studied 6 lung cancer patients who had not yet undergone chemotherapy. Patients were given two doses of docetaxel, one that contained a very small amount of the cancer drug and a 'tracer,' and a second dose that contained a tracer and a therapeutic amount of the drug. Afterwards, researchers conducted PET scanning on the study participants to track the drug. Results showed that the first dose of the drug accurately predicted how much docetaxel the tumor would absorb. They also found that only 1% of the drug was absorbed.

Diet high in sugars and complex carbs strongly linked to colon cancer recurrence

(November 7, 2012 - Insidermedicine) From Boston - A diet high in sugars and and carbohydrates is strongly associated with colon cancer recurrence, according to a report published in the Journal of the National Cancer Institute. Researchers studied over 1,000 advanced colon cancer patients who had undergone surgery and were enrolled in a chemotherapy-trial for their disease. Participants reported their diet during the trial and 6 months afterwards. Results showed that patients whose diet had high levels of complex sugars and carbohydrates were at 80% increased risk of their cancer recurring and dying, when compared to patients with the lowest levels. This increased risk was even greater among patients who were overweight or obese. Lead author of the study, Jeffrey Meyerhardt, had this to say, "Eat less sugar...Our study certainly supports the idea that diet can impact the progression of colon cancer, and that patients and their doctors should consider this when making post-treatment plans."

(November 7, 2012 - Insidermedicine) From Switzerland - Black tea drinkers may be at reduced risk of diabetes, according to a report published in BMJ Open. Researchers reviewed data on black tea consumption in 50 countries across every continent, sales data that was collected by an independent marketing company. They also reviewed data from the WHO on those same countries, analyzing rates of respiratory, infectious, and heart diseases, cancer and diabetes. Using statistical analysis, researchers were able to determine the effect of black tea consumption on these health conditions. Results showed that countries that consumed the most black tea also had the lowest rates of type 2 diabetes. This association was not seen for any of the other health conditions

Signs of aging may also be signs of heart disease

(November 6, 2012 - Insidermedicine) 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.

Stem cells result in great, sustained improvement in heart attack patients
(November 6, 2012 - Insidermedicine) From Louisville - Stem cell ...
(November 6, 2012 - Insidermedicine) From Louisville - Stem cell therapy has been shown to sustain heart function improvement in heart attack patients in a phase 1 clinical presented at the AHA's Scientific Sessions. The trial, known as SCIPIO for Stem Cell Infusion in Patients with Ischemic CardiOmyopathy, randomized 33 patients diagnosed with heart failure after suffering a heart attack to either cardiac stem cells or no stem cells. Researchers found that patients who received the stem cells had great improvement in their heart function, and that this improvement was sustained 2 years following infusion. Patients who did not receive stem cells had no improvement. There were no adverse effects of the treatment. One patient's heart experienced such dramatic improvement that there was no sign of heart failure at all. Said Dr. Roberto Bolli, lead author of the study, "Anyone who looks at his heart now would not imagine that this patient was (ever) in heart failure or that he had a heart attack."

(November 6, 2012 - Insidermedicine) 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 5, 2012 - Insidermedicine) 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.

Black men and women much more likely to develop fatal heart disease

(November 5, 2012 - Insidermedicine) From Alabama - Black men and women are much more likely to develop fatal heart disease, according to a report presented at the AHA's Scientific Sessions. Researchers studied over 24,000 adults for just over 4 years, none of whom had heart disease at the beginning to the study. Results showed that black men and women had twice the rate of fatal coronary heart disease when compared with white men and women. The study authors suggest that "increased emphasis on optimizing well-established CHD risk factors among blacks could potentially reduce these disparities."
