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.

HIV VIDEO: Stem Cells Might Be Used to Treat HIV, Communication Breakdown in Brain Linked with Schizophrenia, Wealth Disparity Between Female and Male Researchers
(March 31, 2010 - Insidemedicine) From Scotland - According to ...
(March 31, 2010 - Insidemedicine) From Scotland - According to a report presented at the meeting for the Society for General Microbiology, stem cell therapy could in the future be used to treat HIV. Researchers are studying a new approach that would deliver antiviral DNA to the immune system, consequently arming it with a defense against viral infection. This approach would involve extracting blood stem cells from the patient's bone marrow and infusing them with this antiviral DNA. From New York - Scientist have identified a disrupted brain connection that may be associated with schizophrenia, according to a report published in the journal Nature. Researchers studied mice that were altered to have a genetic mutation known to occur in schizophrenics. They found that these mice had a communication breakdown in their brains between the hippocampus and prefrontal cortex, an area known to affect cognitive behavior. And finally, from Boston - Female researchers are paid significantly less than males, according to a report published in the journal Academic Medicine. Surveying over 2000 researchers, results showed that females earned an average of over $13,000 yearly less than males--an aspect that the study authors were at a loss to explain.

(March 30, 2010 - Insidermedicine) From Germany - Chocolate may lower blood pressure and reduce risk of heart disease, according to a report published in the European Heart Journal. Researchers studied nearly 20000 adults for 10 years, finding that those who ate an average of 7.5 grams of chocolate each day had lower blood pressure as well as a 39% reduced risk of suffering a heart attack or stroke. From Michigan - According to a report published in the Journal of Clinical Oncology, radiation therapy following mastectomy may be underused. Researchers studied over 2000 breast cancer patients, finding that 95% of those who underwent a lumpectomy were treated with radiation therapy afterwards, while only 78% who underwent mastectomy received radiation. And finally, from Rochester - According to a report published in the Journal of General Internal Medicine, young adults rely on emergency departments far more than any other age group. Researchers reviewed data on over 17000 visits to the emergency room and over 14000 outpatient visits, finding that 22% of all young adult healthcare visits were made to the emergency room, while only 13% of children visits and 8% of visits for people over 30 were made to the ER.

(March 29, 2010 - Insidermedicine) From Boston – Researchers may have identified a new approach type 2 diabetes, according to a report published in the journal Nature Medicine. Researchers found a certain cellular pathway that fails when one becomes obese, subsequently stifling the body’s response to insulin. When this pathway was activated in obese mice, however, researchers found that the rodent’s blood glucose levels normalized. From Toronto – According to a report published in the Canadian Medical Association Journal, pregnant women are more likely to suffer deep vein thrombosis on their left side. Out of over 1000 studies reviewed, researchers found only a limited amount that examined DVT in pregnant women. From these studies however, researchers were able to discern that DVT is in fact common in pregnancy, and typically found in the left leg. And finally, from Spain – According to a report presented at the European Breast Cancer conference, women who breastfeed longer may be at increased risk of developing aggressive breast tumors. Researchers studied over 14,000 women for 10 years, finding that those who breastfed their child longer than 6 months had 2x increased risk of developing grade III breast cancers.

(March 26, 2010 - Insidermedicine) From Spain - According to a report presented at the European Breast Cancer Conference, treating breast cancer patients with beta-blockers may reduce their risk of metastasis. Researchers studied over 450 breast cancer patients, finding that those who were already taking beta-blockers to treat hypertension also had a dramatically reduced risk of recurrence and metastasis, as well as a 71% lower risk of dying from the disease. From Oxford - Scientists have identified two genes related to autism, according to a report published in the journal Molecular Autism. Studying over 650 families, researchers found that two genes associated with brain development known as LRRN3 and LRRTM3 were connected to susceptibility of autism spectrum disorders. And finally, back to Spain - According to another report presented at the European Breast Cancer Conference, HER2 levels during breast cancer therapy may be a predictor of the patients response to treatment. Researchers studied nearly 200 breast cancer patients, finding that those who had higher levels of HER2 at the onset of treatment and saw their levels decline by at least 20% were more likely to respond well to their chemotherapy.

(March 25, 2010 - Insidermedicine) From San Francisco - According to a report published in the Clinical Journal of the American Society Nephrology, many Americans suffer from kidney disease and do not know it. Researchers studied nearly 8200 adults, finding that 42% of those with undiagnosed diabetes also had chronic kidney disease, while CKD was seen in 18% of those with prediabetes. From Switzerland - Scientists provide new insight into how tumors hide from the immune system in a report published in the journal Science. Researchers found that a particular protein that is normally secreted by the lymph nodes to signal the immune system to start working is also secreted by tumors. In this way, the tumor signals to the immune system that it is a friend not foe and consequently goes undetected by the immune system. And finally, from Pennsylvania - According to another report published in the Clinical Journal of the American Society Nephrology, most patients awaiting a kidney donation are willing to accept one from a donor that puts them at increased risk of infection. Researchers surveyed nearly 200 potential kidney transplant patients. 59% of these patients said they would--under some conditions--accept a kidney from a donor even if they were at increased risk of viral infection.

BREAST CANCER VIDEO: Breast Cancer Recurrence and Metastasis Risk, Rise in Caesarian Sections In US, HIV Patients at Increased Risk for Community Acquired MRSA
(March 24, 2010 - Insidermedicine) From Spain - According to ...
(March 24, 2010 - Insidermedicine) From Spain - According to a report presented at the European Breast Cancer Conference, recurrence of breast cancer is the strongest indicator of eventual metastasis and death. Researchers studied nearly 8,000 breast cancer patients for almost 11 years. They found that recurrence of breast cancer in the original area of the tumor was the strongest prognostic factor of eventual metastasis of the disease, even for women who were disease free for ten years. From Atlanta - According to a report released by the CDC, the amount of Caesarean sections performed in the US are on the rise. Researchers found that in 2007, c-sections rose to become 32% of all births--a number that represents a 71% increase from 1996. And finally, from Chicago - HIV patients are at significantly increased risk of community acquired MRSA, according to a report published in the journal Clinical Infectious Diseases. Reviewing regional data over a seven year period, researchers found that HIV patients were 6x more likely than non-HIV patients to contract CA-MRSA.

(March 23, 2010 - Insidermedicine) From Sweden - A high systolic blood pressure reading in chest pain patients admitted to an ICU may be associated with a favorable outcome, according to a report published in the Journal of the American Medical Association. Researchers reviewed data on nearly 120,000 patients admitted to an ICU with chest pain, finding that patients with a high supine systolic blood pressure reading had the most favorable 1 year prognosis. From Minnesota - According to another report published in the Journal of the American Medical Association, clinical trials tend to exaggerate their positive effects when stopped early. Researchers studied nearly 100 clinical trials that were stopped early, finding that these truncated trials had either misleading or exaggerated treatment effects. And finally, from Boston - According to a report published in the journal Public Library of Science Medicine, there are 4 preventable factors that combine to reduce life expectancy in the US. Researchers studied national surveys, finding that smoking, high blood pressure, high blood sugar and obesity combine to reduce life expectancy by 4.1 years in women and 4.9 years in men.

(March 22, 2010 - Insidermedicine) From Washington - The United States House of Representatives has approved a landmark legislation aimed at overhauling the American health care system. The legislation intends to provide health care for the 32 million Americans currently uninsured, aiming to create new regulations to preclude insurance companies from denying coverage and making insurance premiums unaffordable. From Boston - According to a report published in Circulation: Journal of the American Heart Association, African Americans are less likely to receive evidence-based care following a stroke than Caucasians or Hispanics. For five years, researchers studied nearly 400,000 black, white and hispanic stroke patients. Results showed that black stroke patients were 10% less likely than white patients to receive 'defect free care'--or, to receive all of the treatments that they are eligible for. And finally, from North Carolina - According to a report published in the American Journal of Roentgenology, x rays are frequently inaccurate in diagnosing pelvic and hip fractures. Researchers studied nearly 100 patients who underwent both x ray and MRI for suspected hip and pelvic fractures. Of 13 patients with a normal x ray, MRI found 23 fractures; while 11 patients who had an x ray that suggested a fracture had an MRI that showed none at all.

(March 19, 2010 - Insidermedicine) From Atlanta - According to a report presented at the International Conference on Healthcare-Associated Infections, simple infection control measures appear to work against MRSA. For seven years, researchers studied the effect that measures such as hand hygiene, chlorhexidine bathing, and device-related efforts had against hospital acquired infections. They found a 91% reduction in MRSA bloodstream infections, 62% reduction in MRSA catheter infections, and 92% reduction in MRSA ventilator related pneumonia. From California - Extreme obesity is becoming more and more common among children in the US, according to a report published in the Journal of Pediatrics. Researchers studied over 700,000 children, finding that 37% of the children were overweight and 19% were obese, while 5% of girls and 7% of boys in the study were extremely obese. And finally, from Australia - According to a report published in the British Medical Journal, pregnant women who get the H1N1 flu are at increased risk of critical illness. Researchers studied over 200 women admitted to ICU with confirmed H1N1, finding that pregnant women were 13x more likely to be hospitalized with a critical illness.

(March 18, 2010 - Insidermedicine) From Boston - Stress during pregnancy may increase risk of asthma in the child, according to a report published in the American Journal of Respiratory and Critical Care Medicine. Researchers studied 557 families, analyzing the child's umbilical cord for cytokines--a molecule that allows cells of the immune system to communicate with one another. They found varying levels of cytokines in mothers who lived or worked in a high stress environment, an aspect researchers believe increases the child's risk of allergy and asthma later in life. From Australia - According to another report published American Journal of Respiratory and Critical Care Medicine, scientists have developed a technique that may be able to reduce tobacco smoke damage to the lungs. Researchers blocked the protein GM-CSF in one group of mice, while another served as controls. Exposing both groups to cigarette smoke, researchers found that the mice without the protein suffered significantly less lung inflammation than controls. And finally, from France - The element Selenium may have a protective effect against diabetes, according to a report published in the journal Nutrition and Metabolism. Researchers studied over 1000 adults for nine years, finding that men with the highest selenium concentrations in their blood had a much lower incidence of dysglycemia (blood sugar metabolism disorders such as diabetes.)
