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.

Eating Grapes May Have Heart Benefits, Toys in Doctors' Offices Carry Cold Viruses, Nicotine Addiction Severity On the Rise
(October 29, 2008 - Insidermedicine) From Michigan - According to ...
(October 29, 2008 - Insidermedicine) From Michigan - According to research in the Journal of Gerontology: Biological Sciences, eating grapes may be beneficial for the heart. In a study of rats, researchers found that those who were fed grape powder had lower blood pressure, better heart function, reduced inflammation in their bodies and less heart muscle damage. The researchers believe that the antioxidant properties of flavonoids may be responsible for these effects. From Virginia - According to research presented at the Interscience Conference on Antimicrobial Agents and Chemotherapy, toys in pediatricians' waiting rooms may expose children to cold viruses. Researchers took swab samples from toys in a pediatrician's office, and found that 1 in 5 toys tested positive for rhinoviruses or influenza B. While the presence of viral RNA does not necessarily mean the toys are infectious, the researchers noted that even cleaning the toys with a disinfectant cloth only minimally decreased the presence of viral remnants. And finally, from California - According to research presented to the American College of Chest Physicians, nicotine addiction in the U.S. has reached a 15 year high. In the study, researchers used questionnaires to assess the pre-treatment nicotine dependence of over 600 participants. Overall, the researchers found that the severity of nicotine dependence had gone up 12% between 1989 and 2006, and the percentage of those considered highly dependent went up by 32%.

Selenium and Vitamin E Do Not Prevent Prostate Cancer, New Treatment for Rheumatoid Arthritis, Gene Response to Common Cold Studied
(October 28, 2008 - Insidermedicine) From Cleveland - According to ...
(October 28, 2008 - Insidermedicine) From Cleveland - According to research from the National Cancer Institute, selenium and vitamin E supplements do not prevent prostate cancer, despite earlier research to the contrary. In a study of 35,000 men, researchers found that, not only did the supplements not prevent prostate cancer, but those who took vitamin E alone actually had a slightly increased risk for prostate cancer, and those taking selenium alone had a slightly increased risk of diabetes. From the UK - According to research presented to the American College of Rheumatology, a new combination treatment may provide fast, effective relief from rheumatoid arthritis. In a study of 500 patients with moderate to severe rheumatoid arthritis, researchers found that those who received both methotrexate and the new drug tocilizumab achieved significantly better results than those treated with methotrexate alone. In addition, those who received tocilizumab achieved remission 10 weeks sooner than the control group. And finally, from Calgary - A study published in the American Journal of Respiratory and Critical Care Medicine is the first to look at how every gene in the body responds to a common cold virus. The researchers found that the cold virus activates dozens of immune system genes, and also appears to shut down some genes. The researchers believe that these findings provide a blueprint for future research in developing cold treatments that boost the body's natural defenses.

(October 27, 2008 - Insidermedicine) From the UK - According to research in Nature Biotechnology, scientists have developed a genetically modified tomato that could help fight cancer and increase life span. Researchers took genes from a snapdragon plant, inserted them into tomato plants and grew purple tomatoes that are high in anthocyanins, which have been shown in previous studies to protect against cardiovascular disease, diabetes, obesity and some cancers. From Houston - According to research presented at the Interscience Conference on Antimicrobial Agents and Chemotherapy, patients with pneumonia are more likely to suffer from acute coronary syndrome. In a study of over 200 patients, researchers found that nearly 11% of those with pneumonia had acute coronary syndrome, compared to 1.5% of controls. However, the study was unable to determine causation, and researchers are unsure whether pneumonia makes people more susceptible to mild heart failure, or vice versa. And finally, from San Francisco - According to research in the Journal of the American Geriatrics Society, physical activity can improve mental function in the elderly. In a study of over 2,700 elderly women, those who were the most active were better able to to plan and execute daily tasks than those who were less active. Unlike previous studies which relied on self-reporting, the current study made use of a device called an actigraph, which continuously measures motion.

Acomplia Increases Risk of Psychiatric Disorders, ADHD Linked to Nicotine Dependence, Flavonoid Increases Effectiveness of Cancer Treatment
(October 24, 2008 - Insidermedicine) From London - According to ...
(October 24, 2008 - Insidermedicine) From London - According to the European Medicines Agency, the risks associated with the anti-obesity drug Acomplia outweigh the benefits. Researchers examined evidence from ongoing clinical trials and found the increased risk for psychiatric disorders such as depression unacceptable, noting that the risk was double in those taking Acomplia. The agency recommends that doctors stop prescribing Acomplia and review the treatment of patients currently taking the drug. From Boston - According to research in the Journal of Pediatrics, smokers with ADHD are more susceptible to nicotine addiction. In a study of 80 patients with ADHD and 86 controls, researchers found that, among ADHD patients, 69% had smoked at some point in their lifetime, compared to 44% in the control group. In addition, 41% of ADHD patients were current smokers, compared to only 17% of controls. And finally, from California - According to research in the Proceedings of the National Academy of Sciences, a compound found in many fruits and vegetables may increase the effectiveness of cancer treatments. The compound, a flavonoid called apigenin, was found to make cancer cells more vulnerable to a chemotherapy drug in a lab dish. These findings may lead to new drugs modeled after this compound that could achieve the same effect clinically. For Insidermedicine in 60, I'm Dr. Susan Sharma.

Pneumonia Vaccine Recommended for Smokers, Thyroid Disorders Linked to Glaucoma, Depression During Pregnancy Increases Risk for Preterm Delivery
(October 23, 2008 - Insidermedicine) From Washington - U.S. federal ...
(October 23, 2008 - Insidermedicine) From Washington - U.S. federal advisers have recommended that smokers be vaccinated against pneumonia, along with children and the elderly. If this recommendation is accepted by the CDC, it would be the first vaccine recommendation targeted specifically at smokers. Previous studies have shown that the risk of pneumococcal disease rises with the number of cigarettes smoked, and smokers account for half of otherwise healthy adults with pneumococcal infections. From Alabama - According to research in the British Journal of Ophthalmology, thyroid disorders increase the risk for glaucoma. In a study of over 12,000 adults, researchers found that having a thyroid problem at some point in life was linked with a 38% increased risk for developing glaucoma. The researchers suggest that there is a biological link between thyroid problems and glaucoma which accounts for these findings. And finally, from California - According to research in the journal Human Reproduction, depression during pregnancy increases the risk of premature birth. In a study of nearly 800 pregnant women, researchers found that those with mild depression had a 60% increased risk for preterm delivery, while those with severe depression were more than twice as likely to deliver their baby early. The researchers suggest that emphasizing the treatment of depression in prenatal care could lead to a significant reduction in preterm deliveries. For Insidermedicine in 60, I'm Dr. Susan Sharma.

Food Allergy Rates Rising Among Children, TMS Approved for Major Depression, Eating Quickly Can Contribute to Obesity
(October 22, 2008 - Insidermedicine) From Atlanta - According to ...
(October 22, 2008 - Insidermedicine) From Atlanta - According to the CDC, more children than ever are being diagnosed with allergies. It has been reported that about 3 million children in the U.S. have a food or digestive allergy, which represents an 18% increase over the past 10 years. The report also found that, in 2007, 29% of children with a food allergy also had asthma, compared to only 12% of children without food allergies. From Washington - The FDA has approved transcranial magnetic stimulation for treating patients whose depression has not responded to anti-depressants. This non-invasive treatment uses a magnetic device to stimulate the brain by sending magnetic pulses through the skull, and does not carry the risks associated with other interventions such as surgically implanted electrodes. Currently, each TMS treatment session can cost between 200 and 300 dollars. And finally, from Japan - According to research in the British Medical Journal, those who eat quickly until they are full are much more likely to be overweight. In a study of over 3,200 people, researchers found that those who ate their food quickly and until they felt full had a higher BMI and were 3 times more likely to be overweight than those who did not eat until they were full and ate more slowly. The researchers encourage healthy eating habits such as eating slowly, serving appropriate portion sizes, and eating as a family in a non-distracting environment.

Western Diet Increases Heart Attack Risk, Strokes Milder Among Those Who Exercise, Many Parents Do Not Realize Children Are Overweight
(October 21, 2008 - Insidermedicine) From Hamilton - According to ...
(October 21, 2008 - Insidermedicine) From Hamilton - According to research in the journal Circulation, a Western style diet increases the risk of heart attack. In a study of over 5,700 heart attack patients and over 10,600 controls, researchers found that those whose daily intake was high in meat, eggs, fried foods and salt were about 30% more likely to have a heart attack than those whose diet was high in fruit and vegetables. Meanwhile, an Oriental diet high in tofu, soy and other sauces did not appear to affect heart attack risk. From Copenhagen - According to research in the journal Neurology, strokes are milder and less likely to cause impairment in those that are physically active. In a study of 295 patients who had suffered a stroke, researchers found that those who were the most physically active were 2.5 times more likely to have had a mild stroke, and half as likely to be left impaired, compared to those who exercised the least. Physical activity is also considered a modifiable risk factor for the prevention of stroke. And finally, from Australia - According to research from the University of Melbourne, many parents do not know if their children are overweight. In a study of over 2,100 children and their parents, researchers found that 49% of parents of overweight children thought their child was of average weight. The researchers suggest that if parents falsely believe their children to be of average weight they are unlikely to help their child correct their weight.

Beta-Blockers Before Surgery Increase Risks, Patch Testing for Allergic Contact Dermatitis, Chest CT Scans Detect Cancer Progression
(October 20, 2008 - Insidermedicine) From Boston - According to ...
(October 20, 2008 - Insidermedicine) From Boston - According to research in the Archives of Surgery, those who receive beta-blockers before undergoing surgery are more likely to suffer a heart attack or die within 30 days. In a study of over 1,200 patients undergoing non-cardiac surgery, researchers found that the rate of heart attack among those taking beta-blockers was nearly 3% compared to 0.74% of controls, and the rate of death was 2.5% compared to 0.25% of controls. From New Hampshire - According to research in the Archives of Dermatology, children and adults who undergo patch testing for allergens are equally likely to have allergic contact dermatitis. In a study of nearly 400 children and over 9,600 adults, researchers found that participants tested positive for at least one allergen at about the same rate: 51% in children and 54% in adults. However, 15% of children reacted to supplemental allergens that are not included in common patch tests. And finally, from Taipei - According to research in the Archives of Otolaryngology - Head & Neck Surgery, chest scans may help detect disease progression in the lungs among those with head and neck cancer. In a study of 270 chest CT scans, researchers found that the rate of abnormal scans was 44% in a follow-up case group, compared to 14% in a new case group. The researchers conclude that chest CT is recommended for high-risk patients, particularly during the follow-up period. For Insidermedicine in 60, I'm Dr. Susan Sharma.

Gene Variant in Brain May Predict Overeating, EPA Releases New Lead Standards, A Walk In the Park May Benefit Children With ADHD
(October 17, 2008 - Insidermedicine) From Oregon - According to ...
(October 17, 2008 - Insidermedicine) From Oregon - According to research in the journal Science, the brain's reaction to food may indicate who is likely to overeat. In a study of 76 women, researchers found that a dopamine-rich center of the brain called the dorsal striatum became active when the participants tasted a milkshake. However, this brain region was far less active in participants who were overweight. The researchers suggest that those who do not derive as much pleasure from food may overeat in order to compensate. From Washington - The Environmental Protection Agency has released new standards for airborne lead particles, marking the first change in federal lead standards in 30 years. The agency has cut the maximum allowable concentrations to a tenth of the previous standard, from 1.5 micrograms per cubic meter of air, to just 0.15 micrograms. Lead is associated with impaired neural development in children and cardiovascular disease and premature death in adults. And finally, from Illinois - According to research in the Journal of Attention Disorders, taking a walk through the park can improve attention in children with ADHD. In a study of 17 children, researchers found that going for a walk improved the ability of the children to concentrate, especially if they had strolled through a "green" area, such as a park. These findings suggest that physical environment is important, and adding a dose of nature to a child's routine may help improve their attention.

Bottled Water No More Pure Than Tap Water, U.S. Ranked 29th for Infant Mortality, Extensive Cellphone Use May Cause Rash
(October 16, 2008 - Insidermedicine) From Washington - According to ...
(October 16, 2008 - Insidermedicine) From Washington - According to a study by the non-profit Environmental Working Group, bottled water is no more pure than tap water. In a study of 10 leading brands of bottled water sold in the U.S. the researchers found an average of 8 pollutants in each, including disinfection byproducts, traces of pain medication, fertilizer residue and bacteria. Bottled water sales in the U.S. exceed $12 billion annually. From Atlanta - According to the CDC, the United States has fallen behind other developed nations in terms of infant mortality. According to the study, the U.S. ranks 29th with an infant mortality rate of 6.78 deaths per 1,000 live births. This was compared to 22 countries with infant mortality rates below 5 deaths per 1,000, including several Scandinavian and East Asian countries with rates below 3.5 deaths per 1,000. And finally, from London - According to the British Association of Dermatologists, extensive cellphone use may cause a facial rash. Dubbed "mobile phone dermatitis", the condition is caused by an allergic reaction to the nickel surface of cellphones after long periods of time are spent on the devices. In a previous study, researchers tested 22 popular cellphones from 8 manufacturers and found nickel in 10 of them. For Insidermedicine in 60, I'm Dr. Susan Sharma.
