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.

(December 11, 2009 - Insidermedicine) From Montreal - Scientists have discovered a molecule that provides a natural defense against cancer, according to a report published in the journal Molecular Cell. Researchers found that the SOCS1 molecule works to prevent cancer by impeding the excessive activity of cytokines that is seen with the disease. The researchers also found that reintroducing the SOCS1 molecule into tumor cells precluded the cells from multiplying, thereby rendering the cancer dormant. From St. Louis - According to a report published in the Journal of the American College of Cardiology, obese people can improve their heart function with even moderate weight loss. Researchers studied 60 obese patients for two years, subjecting the participants to low calorie diets and roughly 3 hours of exercise per week. Results showed that participants hearts were able to pump and relax better, and that their carotid artery walls and the heart muscle itself both decreased in thickness. And finally, from Texas - Researchers have found a naturally produced molecule that may help delay progression of amyotrophic lateral sclerosis (or, Lou Gehrig's disease), according to a report published in the journal Science. Researchers discovered that the molecule microRNA-206 is produced by skeletal muscle as a response to nerve damage, pushing healthy nerves to send new 'branches' towards those nerves that have been affected, temporarily regenerating them. The molecule was shown to limit ALS symptoms and even lengthen life in a mouse model.

(December 10, 2009 - Insidermedicine) From Ottawa - Canadians should be wary of taking certain acai berry products, according to a warning from Health Canada. The warning comes following the discovery that shipments of acai berry products crossing the Canadian border were found to contain sildenafil--a medication for erectile dysfunction. Sildenafil should not be taken unless supervised by a doctor, as it is a prescription medication and people with heart problems may be at increased risk of stroke and heart attack should they take the drug. From Leeds - According to a report published in the journal Cell, researchers may have found a new approach to treating blood clots. Currently, most patients with blood clots are treated with the anticoagulant Warfarin--a medication that thins the blood but also puts the patient at risk of excessive bleeding if they get injured. Researchers have now discovered, however, that the molecule polyphosphate contributes to the blood clot in the artery without adversely affecting the patient's wound healing ability--a discovery that could make the molecule a new target in blood clot treatments. And finally, from California - Moderate alcohol consumption significantly increases a woman's risk for breast cancer recurrence, according to research presented at the 2009 San Antonio Breast Cancer Symposium. Researchers studied nearly 1,900 breast cancer survivors for eight years. They found that three to four alcoholic drinks per week, regardless of the type, increased breast cancer recurrence risk by 30%, with obese women and postmenopausal women at the greatest risk.

(December 9, 2009 - Insidermedicine) From Baltimore – According to a report published in the New England Journal of Medicine, scientists may have discovered a way to reverse severe sickle cell disease in adults. Researchers studied 10 patients with severe sickle cell disease, administering an IV transplant of blood forming stem cells from healthy donors along with the drug rapamcyin. Results showed that 90% of these patients had normal red blood cells and consequently saw their organ damage reversed. From Finland – According to a report published in the journal Pediatrics, delayed introduction of solid foods into an infant’s diet may lead to food allergies later in life. Researchers reviewed data on nearly 1000 children who took part in a large birth cohort study. They found that late introduction (defined as 6 months) of eggs, wheat and oats into the child’s diet had a significant association with food sensitivity at age 5. And finally, from Germany – Bone marrow cells may be able to reduce patients risk of suffering a second heart attack, according to a report published in the journal Circulation: Heart Failure. Researchers randomized over 200 heart attack survivors who had undergone stent placement to either an infusion of progenitor cells from their own bone marrow into the damaged artery or a placebo solution. Results showed that none of the bone marrow infusion group suffered a second heart attack compared with 7 in the placebo group, a difference deemed statistically significant

INSIDERMEDICINE VIDEO: Child Cancer Survivors At Increased Risk of Heart Disease, Newborn Screening Test for Lymphopenia, Pistachios May Reduce Risk of Lung Cancer
(December 8, 2009 - Insidermedicine) From Minnesota - According to ...
(December 8, 2009 - Insidermedicine) From Minnesota - According to a report published in the British Medical Journal, pediatric cancer survivors are at increased risk of heart disease as young adults. Researchers compared over 14, 000 cancer survivors taking part in a long term study with nearly 4,000 of their siblings. Results showed that childhood cancer survivors were more likely to develop heart failure, heart attacks, and heart inflammation in young adulthood. This risk was apparent even up to 30 years following cancer treatment. From Wisconsin - DNA screening of newborns is able to detect T-cell lymphopenia, according to a report published in the Journal of the American Medical Association. Researchers screened over 70,000 samples of newborn blood screening cards. They found that screening the amount of T-cell receptor excision circles (TREC) in the blood was able indicate whether or not the child suffered from T-cell lymphopenia (low levels of white blood cells). And finally, from Houston - A daily dose of pistachios may be able to reduce risk of lung cancer, according to a report presented at the American Association for Cancer Research Frontiers in Cancer Prevention Research Conference. Researchers divided 36 participants into two groups: one ate 68 grams of pistachios a day while the other maintained their normal diet. Results showed that the pistachio group had a significant rise in their amount of gamma-tocopherol--a form of Vitamin E that is known to provide some protection against lung cancer.

INSIDERMEDICINE VIDEO: Genetic Cause For Some Obesity, New Drug For Cystic Fibrosis, Venous Thromboembolism Treatment
(December 7 - Insidermedicine) From Cambridge (UK) - According to ...
(December 7 - Insidermedicine) From Cambridge (UK) - According to a report published in the journal Nature, genetic mutations, known as copy number variants (where sections of DNA are deleted or duplicated), have been identified as a cause of severe childhood obesity. The researchers examining 300 severely obese children found that some of these children were missing sections of chromosome 16. They believe that a specific gene on this chromosome, SH2B1, plays a role in regulating weight and blood sugar. From California - Researchers have found a compound that may restore some lung function in those who suffer from cystic fibrosis, according to a report published in the online edition of Nature Chemical Biology. The drug suberoylanilide hydroxamic acid (SAHA), originally used to treat lymphoma, was able to restore 28% of normal lung cell function in cells taken from cystic fibrosis patients. While further research is necessary, this may one day ease the symptoms and improve the quality of life of those who suffer from cystic fibrosis. And finally, from Hamilton - A more convenient oral medication for those with the clotting disorder venous thromboembolism may soon be available. VTE is usually treated with the blood thinner warfarin, which requires patients to carefully watch their diet and has known interactions with other drugs. According to a new report published online by The New England Journal of Medicine, dabigatran etexilate is as safe and effective as warfarin, without the need for such careful monitoring or dose adjustment.

(December 4, 2009 - Insidermedicine) From Atlanta – Certain childhood cancers are more likely to recur, according to a report published in the Journal of the National Cancer Institute. Analyzing data from the Childhood Cancer Survivor Study in which over 12,000 pediatric cancer survivors were evaluated, researchers found that the overall cancer recurrence rate was 4.4% at 10 years, and 6.2% at 20 years. However, ewing sarcomas had a recurrence rate of 13% at 20 years and astrocytoma had a recurrence rate of 14.4% after 20 years. From Denmark - Researchers have been unable to connect cell phone usage to the development of brain tumors, according to another report published in the Journal of the National Cancer Institute. Using information from 4 Scandinavian countries, researchers found no significant difference in brain tumor rates from 1974 to 2003. Though there was an increase in meningioma occurrence among women, most of this increase was attributed to women over the age of 60--a group not considered to be heavy cell phone users. And finally, from Los Angeles – Cannabis may be helpful for patients with multiple sclerosis, according to a report published in the journal BMC Neurology. Researchers reviewed several controlled trials analyzing effects of cannabis extracts on MS symptoms. 5 out of 6 of these trials noted that cannabis use resulted in improvements in mobility as well as a reduction of spasticity (a symptom in which the central nervous system tells muscles to contract or tense up).

INSIDERMEDICINE VIDEO: Smoking Linked to Colorectal Cancer Risk, Gene Connected to Medulloblastoma Identified, Secondhand Smoke Exposure Raises Risk of Breast Cancer
(December 3, 2009 - Insidermedicine) From Philadelphia - According to ...
(December 3, 2009 - Insidermedicine) From Philadelphia - According to a report published in the journal Cancer Epidemiology, Biomarkers & Prevention, scientists have identified a strong connection between cigarette smoking and colorectal cancer. For 13 years, researchers followed over 180,000 people aged 50-74. They found that people who smoked for more than 40 years had up to a 50% raised risk of developing either colon or rectal cancer. From Texas - Scientists have pinpointed a gene linked to medullobalstoma, according to a report published in the journal Science. Researchers genetically altered mice specifically to develop medulloblastoma--or, the deadliest form of brain cancer. However, they found that by shutting down the production of the gene Atoh1 they were able to prevent these mice from actually developing medulloblastoma, an aspect that researchers believe may lead to a new target in the fight against brain cancer. And finally, back to Philadelphia - Long term exposure to secondhand smoke raises risk of breast cancer, according to another report published in the journal Cancer Epidemiology, Biomarkers & Prevention. Researchers surveyed over 57,000 women who had no smoking history, but had experienced exposure to second hand smoke at home, work, or social settings. They found that women with high amounts of exposure to secondhand smoke during adulthood, primarily postmenopausal women, had an increased risk of breast cancer. Exposure under the age of 20, however, did not appear to raise this risk.

INSIDERMEDICINE VIDEO: Balancing Protein Good For Healthy Aging, Ultrasound Beneficial in Detection of Breast Cancer For Some Women, Aspirin Does Not Prevent AMD
(December 2, 2009 - Insidermedicine) From London - According to ...
(December 2, 2009 - Insidermedicine) From London - According to a report published in the journal Nature, balancing the protein in ones diet may be better for healthy aging than limiting caloric intake. Researchers fed fruit flies varying amounts of vitamins, lipids and amino acids in a diet consisting of sugar, water and yeast. The researchers were able to maximize lifespan without compromising fertility of the flies by varying the amount of amino acids, while changing the other nutrients had no such effect. From Chicago - Women at high risk for breast cancer and have dense breasts may benefit from annual ultrasound screening, according to research presented at the annual meeting of Radiological Society of North America. Researchers studied over 600 high risk women, administering mammography and ultrasound every year. Of the 16 women that developed breast cancer, mammography alone detected 50-56% of cancers, while the addition of ultrasound detected 70-94% of cancers. And finally, from Boston - A ten year study into the possible preventive effect of aspirin in age related macular degeneration has yielded no significant results, according to research published online in the journal Ophthalmology. Researchers studied nearly 40,000 women involved in the Women's Health Study, finding that patients who took aspirin every other day had an 18% lower risk of AMD compared with those who took placebo; this difference was deemed nonsignificant.

INSIDERMEDICINE VIDEO: Gestational Glucose Intolerance Linked With Metabolic Syndrome, Stress Response To Surgery Predicts Recovery, Mammography for Some Raises Breast Cancer Risk
(December 1, 2009 - Insidermedicine) From Toronto - According to ...
(December 1, 2009 - Insidermedicine) From Toronto - According to a report published in the Journal of Clinical Endocrinology & Metabolism, pregnant women with glucose intolerance are more likely to demonstrate cardiovascular risk factors after birth. Researchers followed nearly 500 women, looking for the prevalence of metabolic syndrome--a general term for risk factors such as obesity, high blood pressure, and low HDL cholesterol--after birth. They found an association between even mild glucose intolerance and metabolic syndrome just 3 months following birth. From California - Patients may recover quicker from knee surgery if they have a good stress response to the operation, according to a report published in the Journal of Bone and Joint Surgery. Researchers studied 57 patients scheduled for knee surgery, counting the amount of immune cells in the blood up to 10 days before, the morning of, and 30 minutes after the operation. They found that patients whose immune system had a good stress response to surgery showed better knee function and mobility as well as less pain up to a year following the operation. And finally, from Chicago - Radiation exposure from mammography increases the risk of breast cancer in women with a family history or genetic predisposition to the disease. For these high risk women, researchers found that low dose radiation exposure from mammography raised the likelihood of breast cancer 1.5 times, while 5 or more exposures or exposure under the age 20 resulted in a 2.5 times increased risk. This research was presented at the annual meeting of the Radiological Society of North America.

(November 30, 2009 - Insidermedicine) From Boston - Americans born in the Southern 'stroke belt' may be at increased risk of dying from stroke, according to a report published in the journal Neurology. Researchers examined national death records from 1980, 1990, and 2000--looking specifically at Southern states that comprise the 'stroke belt'--North Carolina, South Carolina, Georgia, Tennessee, Arkansas, Mississippi, and Alabama. They found that, for people who were born in and lived in the stoke belt, 74 people per 100,000 died from stroke compared with only 47 per 100,000 who were not born in or did not live there. From Connecticut - According to a report published in the journal Arthritis Care and Research, when patients are given the choice of their medical treatment they will usually take the conservative approach. Researchers subjected over 200 participants to 2 videos outlining medications and their serious, but rare, consequences. Participants were then given two sets of instructions, one in which the doctor essentially chose for the patient and prescribed the medication, and another in which the choice to take the medication was left completely up to the patient. Results showed that the responsibility of choosing medical treatment increased a patient's concern over the side effects and thus led to less willingness to take these treatments. And finally, from California - Too much exercise for middle aged men and women may lead to arthritis, according to a report presented at the meeting of the Radiological Society of North America. Researchers studied 236 adults aged 45-55, finding that those who engaged in higher activity levels suffered more damage to their knees, thereby increasing their risk of developing osteoarthritis later in life.
