Until now, there has been no research dedicated to the importance of Vitamin D supplementation in children with congenital heart disease (CHD). However, over the past few years, researchers at the Children
Researchers at EPFL have built a matchboxsized device that can test for the presence of bacteria in a couple of minutes, instead of up to several weeks. A nanolever vibrates in the presence of bacterial activity, while a laser reads the vibration and translates it into an electrical signal that can be easily read

Widely used treatments for type 2 diabetes have different effects on the hearts of men and women, even as the drugs control blood sugar equally well in both sexes, according to researchers at Washington University School of Medicine in St. Louis.
In particular, the commonly prescribed diabetes drug metformin had positive effects on heart function in women but not in men, who experienced a shift in metabolism thought to increase the risk of heart failure.
‘We saw dramatic sex differences in how the heart responds to the different therapies,’ said senior author Robert J. Gropler, MD, professor of radiology. ‘Our study suggests that we need to better define which therapies are optimal for women with diabetes and which ones are optimal for men.’

New research from Karolinska Institutet in Sweden shows that patients with heart failure have high mortality and often are under-treated. According to a study many more of these patients would benefit from advanced treatment by heart specialists – something that could be decided by a simple evaluation of five common risk factors for early death due to heart failure.
Heart failure affects 2-3% of the overall population and over 10% of the elderly worldwide, and is associated with high risk for early death and reduced quality of life. Drug therapy improves symptoms and reduces mortality and is well used. However, modern heart failure pacemakers, heart pumps and also heart transplantation are of great benefit in selected patients, but are poorly utilised. Earlier studies have shown that, a major reason is that heart failure patients are generally cared for by generalist doctors with limited awareness of these treatments.
In the present study, a team comprising researchers at Karolinska Institutet, Link

Despite major efforts to keep operating rooms sterile, surgical wound infections remain a serious and stubborn problem, killing up to 8,200 patients a year in the U.S. A study by Columbia University Medical Center (CUMC) researchers suggests that narrow-spectrum ultraviolet (UV) light could dramatically reduce such infections without damaging human tissue.
Approximately 200,000 to 300,000 patients suffer surgical wound infections in the U.S. each year, accounting for $3 billion to $10 billion in health-care expenditures, the researchers report. Patients with surgical wound infections, compared with those without such infections, are 60 percent more likely to spend time in an ICU, are five times as likely to be readmitted to the hospital, have twice the mortality rate, have longer hospital stays, and have roughly double the total health-care costs.
Scientists have known for many years that UV light from a standard germicidal lamp (which emits a broad spectrum of wavelengths, from about 200 to 400 nanometers [nm]) is highly effective at killing bacteria; such lamps are routinely used to decontaminate surgical equipment.
‘Unfortunately, this UV light is also harmful to human tissue and can lead to skin cancer and cataracts in the eye,’ said study leader David J. Brenner, PhD, the Higgins Professor of Radiation Biophysics, professor of environmental health sciences, and director of the Center for Radiological Research at CUMC. ‘UV light is almost never used in the operating room during surgery, as these health hazards necessitate the use of cumbersome protective equipment for both surgical staff and patients.’
Dr. Brenner and his team hypothesised that a very narrow spectrum of UV light
