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.

Hispanic women more likely to die of breast cancer; Cardiotoxicity of cancer treatments; Biomarker for ovarian cancer (video)
(December 7, 2011 - Insidermedicine) From the San Antonio Breast ...
(December 7, 2011 - Insidermedicine) From the San Antonio Breast Cancer Symposium, Hispanic women are 20% more likely to die from breast cancer than non-Hispanic white women. The researchers from the University of Kentucky also found that Hispanic women who received chemotherapy were 1.5 times more likely to die from breast cancer. The researchers also pointed out that this difference in cancer survival between Hispanic and non-Hispanic white women does not appear to extend to all-cause or non-breast cancer mortality. From Euroecho, the annual meeting of the European Association of Echocardiography, researchers are working toward developing protocols for evaluating myocardial damage associated with different cancer treatments. As treatments for cancer have improved survival rates in patients, the long-term effects of these treatments are of growing concern. Cardiotoxicity is a common side-effect of many cancer treatments, and the current research projects aim to identify when patients might benefit from changes in cancer therapy, and when protective treatments against cardiotoxicity are indicated. And finally, from Los Angeles, researchers from the University of Southern California have reported progress toward identifying a blood-based DNA biomarker for ovarian cancer. Such a diagnostic tool could prove very useful in both the early detection of ovarian cancer as well as monitoring for recurrence.

(December 6, 2011 - Insidermedicine) From the San Antonio Breast Cancer Symposium, researchers from Lund University in Sweden have revealed that women over the age of 60 who are diabetic and obese have a significantly higher risk for breast cancer. Obesity itself increased breast cancer risk by 55%, while diabetes increased risk by 37%. The researchers also noted breast cancer risk associated with different diabetes drugs, finding the metformin lowered risk by 8%, while glargine almost doubled the risk. From Denmark, young women who eat fish containing omega 3 fatty acids are at reduced risk for heart disease. Looking at women of childbearing age, the researchers from the Technical University of Denmark found that women who never ate fish were at a 90% increased risk of cardiovascular disease as compared to women who ate fish high in omega-3 on a weekly basis. From South Carolina, fitness level trumps body mass index in reducing death risk, according to research out of the University of South Carolina. The researchers found that improving fitness level, even if body weight remains constant, has the effect of lowering risk of death, while no such link existed between changes in body fat percentage or body weight and death risk. This research emphasizes how critically important physical fitness is to health.

From California, researchers at Caltech have found a way to introduce antibodies capable of neutralizing HIV into mice. While the current research demonstrates an effective approach to HIV prevention, it remains to be seen whether this approach can be successfully migrated to a human immune system. From Illinois, researchers at Souther Illinois University School of Medicine have identified a protein released by bone cells which is capable of putting prostate tumour cells into a state of hibernation. Nearly half of prostate cancer patients face recurrence as a result of metastases. The current research sheds light a new target for therapy: aiming to keep prostate tumour cells in their sleep state. And finally, from Washington, levels of health disparity are on the rise, in particular among young American adults. Researchers found that, in particular, Americans born since 1980 exhibit a large gap in perceived health. The data also suggests that the disparity between the healthiest and least healthy will continue over the next 1-2 decades.

(December 2, 2011 - Insidermedicine) From London, researchers have identified and validated a series of objective assessment tools for monitoring the progression of Huntington's disease. Though not impacting the disease directly, the new measures offer an improved assessment of treatments in phase 2 and 3 clinical trials, and greatly advance the development of future treatments. From Boston, researchers at the Dana-Farber Cancer institute have discovered that an immune system stimulant can, in small doses, act as an immune system suppressant. These findings identify a possible treatment course for patients with active, chronic graft-versus-host disease, a common side-effect arising from stem cell or bone marrow transplantation. And finally, from Washington, levels of health disparity are on the rise, in particular among young American adults. Researchers found that, in particular, Americans born since 1980 exhibit a large gap in perceived health. The data also suggests that the disparity between the healthiest and least healthy will continue over the next 1-2 decades.

(December 1, 2011 - Insidermedicine) From New York, researchers at the Albert Einstein College of Medicine have found a link between high blood sugar levels and colorectal cancer in postmenopausal women. The researchers noted a nearly two-fold increase in risk for women in the highest third of baseline glucose levels among the study's participants. Colorectal cancer is the third most common cause of cancer death in the US. From Philadelphia, scientists at the Kimmel Cancer Center at Jefferson University have discovered a possible way to stall breast cancer cells from growing and spreading throughout the body. Metformin, an off-patent drug used to treat diabetes, seems to act as a mitochondrial inhibitor in breast cancer cells, thus cutting off the cancer cells' supply of energy. From Illinois, researchers at Souther Illinois University School of Medicine have identified a protein released by bone cells which is capable of putting prostate tumour cells into a state of hibernation. Nearly half of prostate cancer patients face recurrence as a result of metastases. The current research sheds light a new target for therapy: aiming to keep prostate tumour cells in their sleep state.

Risk of Pulmonary Embolism in Autoimmune Patients; Finding the Causal Mechanisms of Autism; New Therapy for Obstructive Sleep Apnea (Video)
(November 29, 2011 - Insidermedicine) From Sweden, autoimmune disorder ...
(November 29, 2011 - Insidermedicine) From Sweden, autoimmune disorder patients who have been admitted to hospital are at an increased risk of having a pulmonary embolism. The researchers from Lund University in Sweden looked at over 500,000 autoimune hospital admissions and noted a 6-fold increase in risk of pulmonary embolism within the following year. The research suggests that prophylaxis could be warranted in these patients. From Palo Alto, researchers studying Timothy Syndrome brains may have unlocked potential clues as to how autism miswires the brain. Timothy Syndrome is a very rare genetic disease whose sufferers exhibit autism-like symptoms. The current research out of Stanford, in following only a single gene mutation, has made it possible to better track specific causal mechanisms within brain cells that may explain autistic behaviour. And finally, from Baltimore, hypoglossal nerve stimulation may be a viable alternative to continuous positive airway pressure in managing obstructive sleep apnea. Researchers from Johns Hopkins examined the effectiveness of this novel treatment for increasing airflow without rousing patients from sleep. The effectiveness of continuous positive airway pressure is often undermined by low patient adherence.

(November 28, 2011 - Insidermedicine) From Denmark - Cancer survivors are at increased risk of developing a second cancer of the same type, according to a report published in CMAJ. Studying data on the entire population of Denmark, researchers found that those who had survived cancer once were at 2.2x increased risk of developing a second primary cancer of the same type. From New York - Children with ADHD have disrupted brain pathways, according to a report presented at the annual meeting of the Radiological Society of North America. Researchers conducted functional MRI on 18 children with ADHD and 18 controls. Imaging revealed that the ADHD patients had disruptions in the brain pathways involved in visual attention information processing. And finally, from California - Aging stem cells may be the reason why the elderly are prone to leukemia and infections, according to a report published in PNAS. Researchers compared stem cells from 15 elderly people to 28 young people. Though the elderly patient's stem cells proliferated more and were more abundant, the aging stem cells were much less efficient

(November 26, 2011 - Insidermedicine) From Boston – Canned soup greatly increases BPA levels in the blood, according to a report published in JAMA. Researchers studied 75 volunteers, randomized to eat canned soup or fresh soup five days a week. Urinalysis revealed that can soup increased BPA levels by 1,221%. From Oxford - A new report published in the Lancet confirms the safety of statins. 11 year follow up of individuals who participated in the Heart Protection Study found that long term use of statin therapy resulted in increased cardiovascular benefits (reduction in strokes, heart attacks) and even persisted once therapy was stopped. And finally, from Oregon - A new report published in Mental Health and Physical Activity finds that physical activity can improve sleep quality. Studying over 2,600 adults, researchers found that 150 minutes a week of vigorous activity resulted in a 65% improvement in quality of sleep

(November 25, 2011 - Insidermedicine) From Edinburgh - Too much tylenol over the course of a day can cause a fatal overdose, according to a report published in the British Journal of Pharmacology. Researchers studied nearly 700 acetaminophen-induced liver injuries, finding that ingestion of over 4,000 mg of acetaminophen over eight hours resulted in significantly higher death rates than ingestion of the same amount in one sitting. From Oxford - Low-risk pregnant women can safely decide where they will give birth, according to a report published in the BMJ. Studying over 64,000 births, researchers found no significant difference in adverse outcomes in all birth settings among women with had low-risk pregnancies. And finally, from Michigan - A new report published in PLoS ONE identifies a diabetes drug that may help to prevent cancer. Results of a laboratory study found that metformin effectively inhibited the growth of breast cancer cells when exposed to chemicals known to stimulate tumour development

(November 24, 2011 - Insidermedicine) From Iran - Diabetics could benefit greatly from vitamin-D enriched yogurt, according to a report published in BMC Medicine. Randomizing patients with type 2 diabetes to either vitamin D-fortified yogurt drink or a plain yogurt drink, researchers found that the vitamin D yogurt resulted in improved cholesterol and endothelial biomarkers. From France - Intensive chemotherapy greatly improves survival in younger aggressive lymphoma patients, according to a report published in the Lancet. Researchers studied nearly 400 18 year olds with diffuse large B-cell lymphoma, randomizing patients to either intensive chemotherapy or standard treatment. Results showed that patients who underwent the intensive regimen had 56% reduced risk of death. And finally, from Oregon - A new report published in Mental Health and Physical Activity finds that physical activity can improve sleep quality. Studying over 2,600 adults, researchers found that 150 minutes a week of vigorous activity resulted in a 65% improvement in quality of sleep
