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.

Asthma and PTSD Among 9/11 Witnesses, Weight Gain and Colon Cancer, Tobacco Companies Spend Millions on Campus Promotions
(September 11, 2008 - Insidermedicine) From New York - Marking ...
(September 11, 2008 - Insidermedicine) From New York - Marking the seventh anniversary of the World Trade Center attacks of September 11, 2001, New York City's Department of Health and Mental Hygiene has released a report that estimates up to 12,600 adults exposed to the disaster site have developed asthma, and up to 70,000 have developed post-traumatic stress disorder. To address this, the city provides free physical and mental health care to eligible people that were affected by the attacks. From Copenhagen - According to a report in the International Journal of Cancer, men who gain weight as they get older increase their risk of colon cancer. In a study of over 46,000 men aged 40 to 75, nearly one third of all cases of colon cancer diagnosed over an 18-year period were found in men with a BMI over 22.5. The risk was more than double among those with a BMI greater than 30. And finally, back to New York - While fewer college students are smoking than ever before, one in five continue to smoke. According to a report from the American Lung Association, aggressive tobacco marketing on college campuses is to blame. The report states that, in 2005, the tobacco industry spent $1 million a day sponsoring events targeted at college students, while students at 109 of 119 schools surveyed reported being exposed to tobacco promotions at campus events.

Air Pollution Harms Heart Attack Patients, Vitamin B12 Deficiency Increases Risk of Memory Loss, New Diabetes Medication Shows Promise
(September 10, 2008 - Insidermedicine) From Boston - According to ...
(September 10, 2008 - Insidermedicine) From Boston - According to research in Circulation, air pollution can harm those who have suffered a heart attack. In a study of 48 patients, researchers found that the tiny particles found in air pollution can disrupt the ability of the heart to conduct electrical signals. This can be particularly harmful in those with coronary artery disease. The researchers recommend staying indoors on smoggy days and avoiding heavy traffic after being discharged. From Oxford - According to research in the journal Neurology, a vitamin found in meat, fish and milk may help prevent memory loss in the elderly. In a study of 107 volunteers, researchers found that those with the lowest levels of vitamin B12 were much more likely to show signs of brain shrinkage over a five-year period. The researchers are now planning a trial on B vitamin supplements, to see if taking them can slow brain shrinkage in the elderly. And finally, from Rome - According to information presented at the meeting of the European Association for the Study of Diabetes, a new diabetes medication is showing considerable promise. In a study involving over 1,300 patients, combining the new drug, saxagliptin, with metformin resulted in up to 45% of patients experiencing decreases in HbA1c, compared to 29% of those taking placebo. The drug is currently awaiting approval by the FDA. For Insidermedicine in 60, I'm Dr. Susan Sharma.

Level of Exercise Among Children Overestimated, Research on Nicotine Addiction, Physical Activity Prevents Obesity in Genetically Predisposed
(September 9, 2008 - Insidermedicine) From the UK - According ...
(September 9, 2008 - Insidermedicine) From the UK - According to research in the Archives of Disease in Childhood, the amount of exercise that children get has been overestimated. In a study of 130 children aged 6 and 7, the level of exercise that children are getting is around six times lower than previously reported in a national health survey. Children are only getting about 24 minutes of moderate to vigorous physical activity a day, when guidelines recommend at least 60 minutes each day. From Kansas - According to research in the journal Neuropsychopharmacology, nicotine's ability to enhance experiences may explain why it can be difficult to quit smoking. By studying rats, researchers found that nicotine can enhance the level of satisfaction experienced from things such as drinking coffee or spending time with friends. Previous research has primarily examined the drug itself, rather than its effect on other factors, and this new research may lead to more effective tobacco addiction treatments. And finally, from Miami - According to research in the Archives of Internal Medicine, physical activity may prevent obesity in those genetically predisposed for high BMI. A study of over 700 people found that in those with above-average physical activity scores, the genes associated with BMI seemed to have no effect. This finding may lead to more personalized lifestyle recommendations for preventing obesity in those that are genetically susceptible. For Insidermedicine in 60, I'm Dr. Susan Sharma.

MRI Delays Breast Cancer Treatment, Once-Weekly Byetta Controls Blood Sugar, Lack of Sleep Increases Risk of Falls in Elderly Women
(September 8, 2008 - Insidermedicine) From Washington - According to ...
(September 8, 2008 - Insidermedicine) From Washington - According to research presented at the American Society of Clinical Oncology's Breast Cancer Symposium, women newly diagnosed with breast cancer who get an MRI end up delaying cancer treatment by weeks. In a study of 577 patients, those who received an MRI had a three-week delay in the start of treatment, and were also more likely to have a mastectomy than those that did not have an MRI. From Toronto - According to research in the Lancet, the once-weekly diabetes drug Byetta may control blood sugar better than twice-a-day drugs. In a study of 259 patients with type 2 diabetes, those who received Byetta once a week saw their HbA1C levels falls to an average of 6.4%, compared to 6.8% in the twice-daily group. However, the FDA has cautioned that there may be a link between Byetta use and pancreatitis, and is in the process of drafting stronger labeling for the drug. And finally, from Chicago - According to research in the Archives of Internal Medicine, older women who do not get enough sleep are at higher risk of falling. In a study of nearly 3,000 women aged 70 or older, those who slept 5 hours or less per night were more likely to experience two or more falls in a year than those that slept more than 7 hours per night. In other terms, those with a sleep efficiency of under 70% were 1.36 times more likely to experience a fall. For Insidermedicine in 60, I'm Dr. Susan Sharma.

Ibuprofen First for Fevers, Fish Oil Better Than Statins for Heart Failure, Soft Drinks in Schools Increases Consumption
(September 5, 2008 - Insidermedicine) From New York - According ...
(September 5, 2008 - Insidermedicine) From New York - According to research in the British Medical Journal, starting treatment with ibuprofen in children with fever may offer the best results. In a study of 146 children between 6 months and 6 years of age, those that were given ibuprofen first, followed by a combined therapy of ibuprofen and acetaminophen, had their symptoms relieved at a significantly faster rate. Over 24 hours, the combination therapy reduced fever duration by 4.4 hours. From Italy - According to research published in the Lancet, fish oil supplements may be better than statins at treating patients with chronic heart failure. By comparing the results of two different studies, the researchers found that taking an omega-3 fatty acid capsule was slightly more beneficial than taking a statin. The researchers speculate that the positive effect of fish oils on the body's HDL cholesterol levels may be the cause. And finally, from California - According to research in the Journal of the American Dietetic Association, soft drink availability in elementary schools increases consumption among children. In a study of 11,000 fifth graders, researchers found that when soft drinks are available in schools, 25% will consume at least one soft drink in a week, representing about one-half their total consumption. The researchers point to previous studies that have shown even a small increase in daily soft drink consumption can contribute to the development of obesity over the course of adolescence.

MMR Vaccine Not Linked to Autism, Fire Retardant Chemical Found in Children's Blood, Bisphenol A and Brain Function
(September 4, 2008 - Insidermedicine) From New York - According ...
(September 4, 2008 - Insidermedicine) From New York - According to research in the journal Public Library of Science One, the MMR vaccine, which protects against measles, mumps and rubella, is not linked to autism. Researchers examined biopsies for traces of measles and found no difference between the biopsies of children with or without autism. This study contradicts previous research, and the scientists continue to urge parents to have their children vaccinated. From Washington - According to the nonprofit Environmental Working Group, a fire retardant chemical has been found in the blood of children. In a small pilot study of 20 families, the researchers found that in 19 of the families the levels of PBDE, a hormone-disrupting chemical, were about three times as high in the children as in their mothers. The chemical is often used as a fire retardant in electronics, toys and furniture. And finally, from New Haven - In yet another development, Yale School of Medicine researchers have discovered a link between bisphenol A, the chemical found in sturdy plastics, and problems with brain function and mood disorders in monkeys. This finding comes just as federal toxicologists confirmed that "some concern" remains that bisphenol A may be linked to developmental problems in children.

Chickenpox Vaccine Successful, Earwax Removal Not Recommended, Helmet Law Reduces Cycling Deaths
(September 3, 2008 - Insidermedicine) From Atlanta - According to ...
(September 3, 2008 - Insidermedicine) From Atlanta - According to research in the journal Pediatrics, the chickenpox vaccine introduced in 1995 has been a resounding success. Chickenpox-related hospitalizations have been reduced by over 75% and deaths from the disease have become extremely rare. However, experts worry that some parents do not consider chickenpox a serious threat. The disease, which commonly causes rash, itching and fever, can also cause skin infections, pneumonia, brain damage and death in extreme cases. From Virginia - According to the American Academy of Otolaryngology - Head and Neck Surgery, earwax should not be routinely removed. The organization has released new clinical guidelines to help doctors identify patients with impacted wax and noted that, if the ears are functioning, then there is no reason to remove earwax, and that includes the use of cotton swabs. Earwax, a mixture of dead skin, hair and secretion, has both lubricating and antibacterial traits. And finally, from Toronto - According to research in Pediatrics, a law requiring young cyclists to wear helmets has reduced the number of deaths from bike-related injuries. The study found that the number of deaths per year decreased by 52% among bicyclists under the age of 16 after the law came into effect. Passed in 1995, the law states that parents of children under 16 can be fined if their child is not wearing a helmet, and those aged 16 to 17 can be fined directly.

Father's Age Raises Child's Bipolar Risk, Low Serotonin and Seasonal Depression, Active Gaming and Childhood Obesity
(September 2, 2008 - Insidermedicine) From Stockholm - According to ...
(September 2, 2008 - Insidermedicine) From Stockholm - According to research in the Archives of General Psychiatry, having an older father may raise the risk for bipolar disorder. In a study of over 13,000 patients, father's who were over the age of 55 years were 37% more likely to have a child with bipolar disease when compared to much younger fathers. From Toronto - According to research in the Archives of General Psychiatry, PET scans have shown that low levels of serotonin are linked to seasonal depressive disorder. In a study of 88 healthy individuals, serotonin uptake binding potential, detected by PET scanning, was significantly higher in the winter, when compared to scans done in the summer. Serotonin is a neurotransmitter that is important in regulating mood. And finally, from Hong Kong - According to research in the Archives of Pediatrics & Adolescent Medicine, active gaming may help solve childhood obesity. Researchers from the University of Hong Kong showed that children aged 6-12 years can expend up to 400% more calories playing active video games as opposed to playing more sedentary ones.

Magnesium Sulphate & Cerebral Palsy, Beta-Amyloid & Brain Injury, Antipsychotic Drugs & Stroke Risk
(August 29, 2008 - Insidermedicine) From Alabama- According to research ...
(August 29, 2008 - Insidermedicine) From Alabama- According to research in the New England Journal of Medicine, using magnesium sulphate to stop preterm labor lowers the risk of a baby developing cerebral palsy. In a study of over 2,000 women in preterm labor, those treated with magnesium sulphate to stop their contractions had a 45% lower chance of having a baby who was later diagnosed with cerebral palsy. From St Louis - According to research published in Science, a protein linked to Alzheimer's may also be affected by brain injury. In an analysis of 18 patients with traumatic brain injury, researchers from Washington University noted hour-by-hour changes in beta-amyloid levels. While they thought levels would fall as brain function improved, they noted the opposite. While brain injury is known to raise the risk of Alzheimer's, more work needs to be done to better understand the link between these two conditions. And finally, from London - According to research in the British Medical Journal, taking an antipsychotic drug can increase the risk for stroke. Studying nearly 7,000 stroke patients who had received at least one prescription for an antipsychotic medication, researchers noted a doubling of stroke risk while on the medication. In those with dementia, antipsychotic drugs were linked with a 3.5 times raised risk of stroke. For Insidermedicine in 60, I'm Dr. Susan Sharma.
