High vitamin D level improves survival rate in heart failure patients: Study

Survival rates in heart failure patients with reduced levels of vitamin D are lower than in patients with normal levels. This is the finding of a major study carried out at University Medical Center, Groningen, Netherlands. Results also suggest that low levels of vitamin D are associated with activation of the Renin Angiotensin System (RAS - a pivotal regulatory system in heart failure) and an altered cytokine profile.

High levels of OPG hormone associated with adverse outcome after myocardial infarction

Patients suffering with heart failure are more likely to die if they have high levels of a bone hormone called osteoprotegerin (OPG).

Study to determine how often chronic Lyme disease is diagnosed and treated

A study soon to be published in The Journal of Pediatrics attempts to determine how often chronic Lyme disease is actually being diagnosed and treated.

Release of cortisol with fixed regularity can help cope with stress better

If your body releases cortisol with fixed regularity then you can cope with stress better, says NWO-funded researcher Angela Sarabdjitsingh. She investigated the rhythm of corticosterone production in rats. This rat hormone is comparable to the human stress hormone cortisol. Rats deal considerably less well with stress if the pattern of corticosterone release changes. An irregular release pattern is a characteristic of chronic stress and stress-related diseases. It might therefore be possible to treat these by restoring the rhythm.

Social interaction reduces physical damage to brain by heart attack: Research

A new study in mice shows how social support can help minimize some of the worst physical damages to the brain caused by a heart attack.

Neurobiological markers of depression can help tailor antidepressant treatment to the brain

Depression is actually defined by specific clinical symptoms such as sadness, difficulty to experience pleasure, sleep problems etc., present for at least two weeks, with impairment of psychosocial functioning. These symptoms guide the physician to make a diagnosis and to select antidepressant treatment such as drugs or psychotherapy.

Running continuously over 50 or 100 miles may not be good for the heart: Study

In 2009, a study was conducted in UK by Liverpool John Moores University and the Countess of Chester Hospital to assess the effects of running in ultra-endurance races. Typically aimed at super-fit and experienced athletes, these races are held over distances exceeding 50 miles (80 kilometres). The conclusions suggest that some damage is likely to occur to the heart muscle of competitors, while 12 percent of the study group showed signs of significant cardiac damage.

Researchers find heightened activation of limbic circuitry in borderline personality disorder patients

The notion that cutting or burning oneself could provide relief from emotional distress is difficult to understand for most people, but it is an experience reported commonly among people who compulsively hurt themselves.

MGH scientists develop new microfluidic tool for accurate isolation of neutrophils

A team led by Massachusetts General Hospital (MGH) scientists has developed a new microfluidic tool for quickly and accurately isolating neutrophils - the most abundant type of white blood cell - from small blood samples, an accomplishment that could provide information essential to better understanding the immune system's response to traumatic injury. The system, described in a Nature Medicine paper that received advance online release, also can be adapted to isolate almost any type of cell.

Research on trypanosomes can open way for African sleeping sickness drug development

Trypanosomes are parasites responsible for many human and animal diseases, primarily in tropical climates. One disease these parasites cause, African sleeping sickness, results from the bite of infected tsetse flies, putting over 60 million Africans at risk in 36 sub-Saharan countries. The recent 1998-2001 sleeping sickness epidemics in South Sudan, Angola, Democratic Republic of Congo and Uganda killed tens of thousands of people and resulted in over a half million infected individuals.

Peripheral arterial disease increases cardiovascular disease risk: Study

Most patients don't suspect a thing, and yet they are seriously ill: hardening of the arteries - peripheral arterial disease PAD - doubles the risk of premature death and serious cardiovascular events such as heart attack and stroke.

Genetic profiling to predict treatment benefits of ACE inhibitor therapy for CAD

The advantages of prescribing angiotensin-converting enzyme (ACE) inhibitors for stable coronary artery disease (CAD) may be increased by targeting the therapy to the patients most likely to benefit.Clinical characteristics alone do not allow a reliable identification of these patients, so a research programme was carried out at Erasmus University Medical Centre in Rotterdam to develop a genetic profiling model that predicts the treatment benefits of ACE inhibitors and optimises the recommended therapy.

Disruption of structural component in heart muscle cells occurs before decline in heart function

The disruption of a structural component in heart muscle cells, which is associated with heart failure, appears to occur even before heart function starts to decline, according to a new study by researchers at the University of Iowa Roy J. and Lucille A. Carver College of Medicine.
