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.

Heart Disease Genes More Problematic in Diabetics, Inhaled Corticosteroids Increase COPD Pneumonia Risk, Women Less Likely to Receive Liver Transplant
(November 26, 2008 - Insidermedicine) From Boston - According to ...
(November 26, 2008 - Insidermedicine) From Boston - According to research in the Journal of the American Medical Association, genes that raise the risk of heart disease in the general population carry a much greater risk for those with diabetes. In a study of over 1,200 people, researchers found that those with two copies of the 9p21 gene variation but normal blood sugar had twice the risk for coronary artery disease. Meanwhile, diabetics with two copies of the gene had a 4 times greater risk. From Baltimore - In those with chronic obstructive pulmonary disease, inhaled corticosteroids may increase the risk of pneumonia. In a study of over 14,000 patients, researchers from Johns Hopkins found that those who used corticosteroids for at least 6 months were 34% more likely to develop pneumonia than those who received placebo or non-steroid treatment. The researchers suggest that this increased risk must be weighed against the benefits of inhaled corticosteroids. And finally, from North Carolina - Women are less likely than men to receive a liver transplant. In a study of over 45,000 patients waiting for liver transplants, Duke University researchers found that women were 30% more likely to die or become too ill for transplant than men. The researchers suggest that women's smaller average size may play a role, as livers from large donors cannot necessarily be given to small recipients, and children have first priority on smaller livers.

Continuous Blood Pressure Monitoring Better Than Office-Based, Stressful Work Environment Increases Cardiovascular Risks, Diesel Exhaust Linked to COPD Death
(November 25, 2008 - Insidermedicine) From Rio de Janeiro - ...
(November 25, 2008 - Insidermedicine) From Rio de Janeiro - According to research in the Archives of Internal Medicine, continuous blood pressure monitoring is more effective than office-based measurement. In a study of over 550 patients, researchers found that continuous, 24-hour blood pressure monitoring was able to significantly predict cardiovascular events, while office-based measurement was not. The researchers suggest that elevated nighttime pressures may be particularly damaging. From Sweden - According to research in Occupational and Environmental Medicine, heart attacks and other cardiovascular diseases may be created by a stressful office environment. In a study of over 3,200 employees, those who rated their manager's leadership skills as being poor had a 24% increased risk of ischemic cardiovascular events after just one year of work. After 4 years in the same stressful environment employees had a 39% increased risk. And finally, from Boston - According to another study in Occupational and Environmental Medicine, exposure to diesel exhaust is linked to an increased risk of death from chronic obstructive pulmonary disease. Of 30,000 railroad workers studied since 1945, researchers found that over 1,200 of those exposed to diesel exhaust died of COPD, compared to 464 who were not exposed. Overall, exposed workers had a 2.1% increased risk of death from COPD for each year worked. For Insidermedicine in 60, I'm Dr. Susan Sharma.

An Egg A Day May Increase Diabetes Risk, Blood Transfusions Lead to VTE in Cancer Patients, Centenarian Offspring Live Longer and Healthier
(November 24, 2008 - Insidermedicine) From Boston -According to research ...
(November 24, 2008 - Insidermedicine) From Boston -According to research in the journal Diabetes Care, eating an egg every day may increase the risk of type 2 diabetes. In a study of nearly 57,000 people, researchers found that, while eating one egg per week did not affect risk, eating 7 or more eggs per week was associated with a 58% increased risk of diabetes among men, and a 77% increased risk among women. Eggs are a source of dietary cholesterol and contain about 1.5 g of saturated fat. From Rochester - According to research in the Archives of Internal Medicine, cancer patients who receive blood transfusions are more likely to develop blood clots. In a study of over 500,000 cancer patients, researchers found that 7.2% of those who received a red blood cell transfusion developed venous thromboembolism, compared to 3.8% of controls. In-hospital mortality rates were also higher among those who received transfusions, but further study is required to determine causality. And finally, back to Boston - According to research in the Journal of the American Geriatrics Society, children of those who live to be 100 years old have genetic advantages that allow them to live longer. In a study of over 600 elderly adults, researchers found that children of centenarians had a 78% lower risk for heart attack, and an 83% lower risk of stroke. In addition, the children of centenarians were 81% less likely to die during follow-up. For Insidermedicine in 60, I'm Dr. Susan Sharma.

Using Scale Regularly May Lead to Weight Loss, Autumn Birth Increases Asthma Risk, Bisphenol A Exposure May Reduce Fertility
(November 21, 2008 - Insidermedicine) From Minnesota - According to ...
(November 21, 2008 - Insidermedicine) From Minnesota - According to research in the Journal of Adolescent Health, stepping on a scale once per week may encourage overweight teens to lose weight. In a study of 130 adolescents, researchers found that 77% of those who frequently weighed themselves engaged in healthy weight control behaviors, compared to 26% who rarely weighed themselves. As well, those who weighed themselves at least once a week were nearly twice as likely to decrease their caloric intake. From Tennessee - According to research in the American Journal of Respiratory and Critical Care Medicine, babies born in autumn have a higher risk for asthma. By studying the medical records of 95,000 infants, researchers found that those born 4 months before the peak cold and flu season had a 30% higher risk of developing asthma. While genetic risk factors can predispose children to asthma, the researchers conclude that environmental factors must also be considered. And finally, from San Francisco - According to research presented to the American Society for Reproductive Medicine, exposure to bisphenol A, the chemical found in some hard plastics, may reduce fertility. In two studies, one involving 71 men and another studying 44 women, preliminary results have shown that those with higher concentrations of bisphenol A in their urine or blood were more likely to have impaired fertility. The researchers note that these results appear to corroborate the evidence seen in animal studies. For Insidermedicine in 60, I'm Dr. Susan Sharma.

Smoking During Pregnancy Leads to Vascular Damage in Children, Asthma Often Misdiagnosed, Researchers Consider Fast-Food Ad Ban
(November 20, 2008 - Insidermedicine) From the Netherlands - According ...
(November 20, 2008 - Insidermedicine) From the Netherlands - According to research in the journal Arteriosclerosis, Thrombosis, and Vascular Biology, smoking during pregnancy may lead to vascular damage in children. In a study of over 700 people, researchers found that the children of those who smoked had a greater carotid artery intima-media thickness than children of parents who did not smoke. In addition, the offspring of smoking mothers were more likely to weigh more and have higher blood pressure in adolescence. From Ottawa - According to research in the Canadian Medical Association Journal, one-third of those diagnosed with asthma may not actually have the condition. In a study of nearly 500 asthma patients, researchers found that 30% had no evidence of the disease, though many had been taking asthma medication for years. The researchers suspect that some physicians are making a diagnosis based on symptoms, but are not ordering a test to confirm their diagnosis. And finally, from Washington - According to researchers from the National Bureau of Economic Research, banning fast-food ads on television may help fight childhood obesity. After studying data on nearly 13,000 children, the researchers concluded that a ban on fast-food ads could lead to an 18% reduction in the number of overweight children. So far, this type of regulation has only been enacted in Sweden, Norway and Finland. For Insidermedicine in 60, I'm Dr. Susan Sharma.

Stem Cells Prevent Trachea Transplant Rejection, Ginkgo Biloba Not Effective Against Development of Alzheimer's, Early Antiretroviral Treatment for HIV Lowers Infant Mortality
(November 19, 2008 - Insidermedicine) From London - According to ...
(November 19, 2008 - Insidermedicine) From London - According to an article in The Lancet, a woman has received the world's first trachea transplant that did not require the use of immunosuppressants. Scientists developed this personalized transplant by seeding a donor organ with the woman's own stem cells, which prevented her body from rejecting it. The patient is now enjoying a normal life and has shown no signs of rejection after 4 months. From Pittsburgh - According to research in the Journal of the American Medical Association, a popular herbal supplement once thought to benefit memory and cognition has failed to show any effectiveness at preventing Alzheimer's disease. In a study of over 3,000 people, researchers found that 18% of those who took a twice-daily dose of the herbal supplement Ginkgo biloba went on to develop dementia, compared to 16% of those who took placebo. And finally, from the UK - According to research in the New England Journal of Medicine, early diagnosis and treatment of HIV-infected infants can significantly reduce infant mortality and disease progression. In a study of nearly 400 infants, researchers found that initiating early antiretroviral therapy, that is, before clinical criteria were met, resulted in a 76% reduction in the infant mortality rate and a 75% reduction in HIV progression.

Insufficient Sleep Raises Cancer Risk Despite Regular Exercise, IVF Raises Risk of Birth Defects, NSAIDs May Mask Prostate Cancer
(November 18, 2008 - Insidermedicine) From Maryland - According to ...
(November 18, 2008 - Insidermedicine) From Maryland - According to research presented to the American Association for Cancer Research, regular exercise and sufficient sleep can lower the risk for cancer among women. In a study of nearly 6,000 women, researchers found that, while regular exercise can reduce cancer risk, this benefit is lost if women do not get enough sleep. In fact, the women who exercised most regularly but slept less than 7 hours each day had a higher cancer risk than those who got more sleep. From Atlanta - According to research in the journal Human Reproduction, the risk for birth defects is raised by in vitro fertilization. In a study of over 14,000 babies, researchers found that those who were conceived using in vitro fertilization were twice as likely to be born with a cleft lip, and 4 times as likely to be born with gastrointestinal defects. However, these defects remained quite rare in these babies, and the cause remains unclear. And finally, back to Maryland - According to a study presented to the American Association for Cancer Research, taking aspirin or other nonsteroidal anti-inflammatory drugs (NSAID) may mask prostate cancer. In a study of over 1,200 men, researchers found that using aspirin significantly lowered the levels of prostate-specific antigen (PSA), a blood protein used to identify prostate cancer. More research is required to confirm whether NSAID use affects the risk of prostate cancer, or just the ability to detect it. For Insidermedicine in 60, I'm Dr. Susan Sharma.

Preoperative Briefings Reduce Delays, Vitamin C and E Supplements Do Not Prevent Cancer, Blood Testing Offers New Method for Tracking Cancer
(November 17, 2008 - Insidermedicine) From Baltimore - According to ...
(November 17, 2008 - Insidermedicine) From Baltimore - According to research in the Archives of Surgery, preoperative briefings can reduce operating room delays. In the study, 11 surgeons agreed to implement preoperative briefings which involved a 2-minute discussion designed to familiarize the surgical team with each other and the operative plan. These briefings were found to reduce unexpected delays by 31% and decrease the frequency of communication breakdowns. From Washington - According to research presented to the American Association for Cancer Research, vitamin C and E supplements do not have any cancer-prevention value. In a study of nearly 15,000 people, researchers found that taking either vitamin C or vitamin E did not result in a significant reduction in the risk for cancer when compared to placebo. Previous research has also failed to show that these supplements can reduce the risk of cardiovascular disease. And finally, from Boston - According to research in the journal Nature Cell Biology, it may be possible to track cancer and decide on an ideal therapy by using blood tests. Researchers found that tiny sacs released from tumor cells, which carry genetic information about the tumor, can be found in the blood stream. In a study of 25 brain cancer patients, researchers using this new technique were able to uncover specific gene mutations that a surgical biopsy had missed.

Higher Alcohol Taxes Could Save Lives, Placebo Acupuncture and Pregnancy, Exercise Improves Quality of Life Among Heart Failure Patients
(November 14, 2008 - Insidermedicine) From Alaska - According to ...
(November 14, 2008 - Insidermedicine) From Alaska - According to research in the American Journal of Public Health, higher taxes on alcohol could save lives. Researchers examined nearly 30 years of data and found that, whenever Alaska raised its alcohol tax there was a decline in alcohol-related deaths. When the alcohol tax was raised in 1983, alcohol-related deaths dropped by 29%. When the tax was raised again in 2002, there was another 11% reduction in the death rate. From Hong Kong - According to research in the journal Human Reproduction, placebo acupuncture may be more effective than actual acupuncture for women undergoing in vitro fertilization. In a study of 370 women, researchers found that the pregnancy rate among those receiving placebo acupuncture was 55%, compared to 44% among those who received actual acupuncture. The researchers are unsure whether placebo acupuncture is similar to acupressure and improves the pregnancy rate, or if actual acupuncture reduces the pregnancy rate. And finally, from New Orleans - According to research presented to the American Heart Association, exercise can improve quality of life among heart failure patients. In a study of over 2,300 patients, researchers found that those who exercised at least 3 times a week reported a higher quality of life than those who did not exercise. This improvement was achieved in as little as 3 months, and was sustained over 3 years. For Insidermedicine in 60, I'm Dr. Susan Sharma.

Waist Size May Predict Premature Death Risk, Heart Attack and Coronary Angioplasty, Highway Proximity Affects Asthma Control Among Children
(November 13, 2008 - Insidermedicine) From Germany - According to ...
(November 13, 2008 - Insidermedicine) From Germany - According to research in the New England Journal of Medicine, excess weight around the waist may increase the risk of premature death, even among those who aren't overweight. In a study of over 350,000 people, researchers found that each 5 cm increase in waist circumference increased the risk of death by 17% among men, and 13% among women. Waist-to-hip measurement may be a better predictor of obesity-related death than BMI. From New Orleans - According to research presented to the American Heart Association, heart attack patients who undergo coronary angioplasty are more likely to survive if they have the procedure at a hospital that performs more than 83 such procedures each year. In a study of over 5,700 heart attack patients, researchers found that those treated at facilities which performed at least 83 angioplasty procedures a year had a lower death rate, at 2.2%, than hospitals that performed fewer than 46 procedures a year, at 4%. And finally, from Seattle - Living near a highway may worsen asthma control among children. In a study of over 750 children suffering from asthma, researchers found that those living near a freeway were more than 3 times as likely to have the poorest degree of control over their condition. While this study was not designed to determine cause, traffic related pollutants are likely to blame. For Insidermedicine in 60, I'm Dr. Susan Sharma.
