Lower wealth, education and income associated with increased stroke up to age 65

Higher wealth is linked with a lower risk of stroke in Americans between the ages of 50 and 64, but does not predict strokes in those over age 65, researchers reported in Stroke: Journal of the American Heart Association.

Mitochondrial dysfunction and redox signaling in atrial tachyarrhythmia

Researchers at the University Hospital of Magdeburg (Germany) have discovered that atrial tachycardia is associated with mitochondrial dysfunction and oxidative stress followed by the activation of the NF-kB signalling pathway with induction of NF-kB target gene expression in atrial tissue.

New 3-D ultrasound provides clear images of the major arteries within the brain

Using 3-D ultrasound technology they designed, Duke University bioengineers can compensate for the thickness and unevenness of the skull to see in real-time the arteries within the brain that most often clog up and cause strokes.

Beta arrestins found to generate new proteins

Duke University Medical Center researchers have recently discovered that a crucial communications pathway in cells not only stops cells from making proteins, it also makes them go. The team was able to define the way in which proteins called beta arrestins (for their role in stopping signals) also turn on pathways that ultimately lead to the production of new proteins in virtually all tissues in the body.

Metabolic genes tied to inflammatory predictor of heart disease and stroke risk

Two new studies provide evidence that differences in people's blood levels of C reactive protein (CRP) stem in part from natural variation in known metabolic genes. The researchers report their findings in the May American Journal of Human Genetics, a publication of Cell Press.

Cuddles diminishes pain from heel lance in preterm babies

Research published today in the open access journal BMC Pediatrics suggests that very preterm babies, born between 28 and 31 weeks, could benefit from skin-to-skin cuddling with their mother before and during painful procedures such as a heel lance.

Interventions for enhancing medication adherence

Patients often do not take the medicines their doctors prescribe, and a new review of existing research suggests that there is no proven way to get them to follow directions for long periods.

FDA approves Relistor for opioid-induced constipation - helps reduce effects of drugs like morphine on bowel function

The U.S. Food and Drug Administration today approved Relistor (methylnaltrexone bromide) to help restore bowel function in patients with late-stage, advanced illness who are receiving opioids on a continuous basis to help alleviate their pain.

Researchers unravel heparin death mystery

An international team of researchers led by MIT has explained how contaminated batches of the blood-thinner heparin were able to slip past traditional safety screens and kill dozens of patients recently in the United States and Germany.

Menstrual blood - an abundant sources of stem cells

Researchers seeking new and more abundant sources of stem cells for use in regenerative medicine have identified a potentially unlimited, noncontroversial, easily collectable, and inexpensive source - menstrual blood.

Drug-releasing stent shows promise for improving outcomes in patients with coronary artery disease

For patients who underwent angioplasty to open narrowed coronary arteries, the use of stents releasing the drug everolimus reduced the rate of renarrowing of the arteries and significantly reduced the risk of major cardiac events, compared to the widely-used paclitaxel-releasing stents, according to a study in the April 23/30 issue of JAMA, the Journal of the American Medical Association.

Link found between relational victimization in adolescence and depression and anxiety in early adulthood

Spreading rumors and gossiping may not cause bruises or black eyes, but the psychological consequences of this social type of bullying could linger into early adulthood, a new University of Florida study shows.

New understanding of how exercise impacts the heart

For the first time researchers are beginning to understand exactly how various forms of exercise impact the heart. Massachusetts General Hospital (MGH) investigators, in collaboration with the Harvard University Health Services, have found that 90 days of vigorous athletic training produces significant changes in cardiac structure and function and that the type of change varies with the type of exercise performed.

Discovery of new way to prevent cardiac fibrosis

In a study that points to a new strategy for preventing or possibly reversing fibrosis - the scarring that can lead to organ and tissue damage - researchers at the University of California, San Diego School of Medicine have determined that a molecule called Epac (Exchange protein activated by cAMP1), plays a key role in integrating the body’s pro- and anti-fibrotic response.

Number of HIV-positive state and federal inmates drops

Between 2005 and 2006 the number of state and federal prisoners who were HIV-positive decreased 3.1 percent -- from 22,676 to 21,980 inmates, according to a report by the Justice Department's Bureau of Justice Statistics (BJS). Another BJS report estimated that 44 percent of state inmates and 39 percent of federal inmates reported a current medical problem other than a cold or a virus.

Lumbar supports for prevention and treatment of low back pain

Lumbar or lower back supports - those large belts that people wear around their waists when they lift or carry heavy objects - are not very useful for preventing low back pain, according to a new systematic review.

Omega-3 fatty acids for bipolar disorder

Despite intriguing findings that omega-3 fatty acid supplements could alleviate depression symptoms, there is still not enough evidence to say whether omega-3s are useful treatments for people with bipolar disorder, according to a review of recent studies.
