Specific vitamin D levels linked to heart problems Posted: 09 Nov 2015 01:05 PM PST A lack of vitamin D can result in weak bones. Recent studies also show that vitamin D deficiency is linked to more serious health risks such as coronary artery disease, heart attacks, and strokes.

The art of appropriate patient selection for heart procedures Posted: 09 Nov 2015 01:02 PM PST A decline in the number of heart patients undergoing unnecessary PCI (angioplasty) procedures reflects improvements in clinical decision-making and documentation to determine which patients benefit most from the procedure, according to new findings.

Strangled cells condense their DNA Posted: 09 Nov 2015 12:38 PM PST Scientists have been able to see, for the first time, the dramatic changes that occur in the DNA of cells that are starved of oxygen and nutrients. This starved state is typical in some of today's most common diseases, particularly heart attacks, stroke and cancer. The findings provide new insight into the damage these diseases cause and may help researchers to discover new ways of treating them.

How low to go for blood pressure? Lower target could affect millions of Americans Posted: 09 Nov 2015 12:31 PM PST At least 16.8 million Americans could benefit from lowering their systolic blood pressure to 120 mmHg, much lower than current guidelines, according to a new study.

Leading cause of blindness could be prevented or delayed Posted: 09 Nov 2015 11:24 AM PST In a major scientific breakthrough, a drug used to treat Parkinson's and related diseases may be able to delay or prevent macular degeneration, the most common form of blindness among older Americans.

Diabetes drug reduces risk of heart failure and may prevent it, study shows Posted: 09 Nov 2015 11:15 AM PST For the first time, research shows that a type 2 diabetes drug significantly reduces hospitalizations and death from heart failure. At the end of the trial period, investigators found that patients treated with the drug experienced reductions in blood sugar and blood pressure, as well as weight loss, compared to those on placebo. They also found major significant reductions in hospitalizations for heart failure (35%); the combined result for heart failure hospitalization or dying from heart disease (34%); and the combined result for being hospitalized or dying from heart failure (39%).

Complex grammar of the genomic language Posted: 09 Nov 2015 11:02 AM PST The 'grammar' of the human genetic code is more complex than that of even the most intricately constructed spoken languages in the world. The findings explain why the human genome is so difficult to decipher -- and contribute to the further understanding of how genetic differences affect the risk of developing diseases on an individual level.

New genetic cause of a childhood kidney cancer discovered Posted: 09 Nov 2015 11:01 AM PST Genetic mutations in a gene called REST have been shown to cause Wilms tumor, a rare kidney cancer that occurs in children.

Molecular clocks control mutation rate in human cells Posted: 09 Nov 2015 11:01 AM PST A theory that our cells have molecular clock processes ticking inside them, that damage DNA by generating mutations continuously throughout life, has just been proven.These clock-like mutational processes could ultimately be responsible for a large proportion of human cancer and contribute to human aging. Two clock-like mutational processes have been found in human cells and the rates at which the two clocks tick in different human cell types have been determined.

Long-sought protein sensor for the ‘sixth sense’ found -- proprioception Posted: 09 Nov 2015 10:45 AM PST For decades, biologists have been trying to find the crucial sensor protein in nerve endings that translates muscle and tendon stretching into proprioceptive nerve signals. Now, scientists have identified this sensor protein in mice.

Flipping the switch to better see cancer cells at depths Posted: 09 Nov 2015 10:44 AM PST Using a high-tech imaging method, biomedical engineers were able to see early-developing cancer cells deeper in tissue than ever before with the help of a novel protein from a bacterium.

Wealthiest -- not sickest -- patients may have edge in organ transplants Posted: 09 Nov 2015 07:37 AM PST Registering at multiple transplant centers appears to give an edge to wealthy organ transplant patients over those with the most medical need. Multiple listing -- more likely done by wealthy, privately insured patients -- is an effective way to address organ shortages, but undermines the principle of transplanting the sickest patients first and should be reconsidered, researchers said.

Temporary ambulance locations reduces response times and may save lives Posted: 09 Nov 2015 06:20 AM PST Ambulances deployed at temporary locations that can be changed depending on the time of day and accident statistics can reduce response time and may save lives on the way to the hospital.

Movies as a tool to assess acceptability of intimate partner violence Posted: 09 Nov 2015 05:49 AM PST A new study uses passages from movies to analyze the acceptability of violence against women in couple relationships. Intimate partner violence against women by their male partners is a widespread phenomenon across countries and cultures, although in varying degrees. It is the most common form of violence suffered by women, with an estimated global prevalence of around 30%, decreasing to 23.2% in high-income regions, and a global percentage of female homicides committed by their intimate partners of 38.6%, rising to 41.2% in western countries, suggest the authors.

World first blood test reduces risk, increases accuracy in prenatal testing Posted: 09 Nov 2015 05:39 AM PST Research into a simple, accurate and low risk blood test that can detect fetal blood group, sex, and genetic conditions in unborn babies, report scientists.

Despite improvements in blood sugar control, the therapy did not improve the clinical stability or pumping action of the heart in patients with advanced heart failure.

Effectiveness of drug to improve natriuretic peptide levels for chronic heart failure Posted: 09 Nov 2015 05:39 AM PST Medical researchers randomly assigned 456 patients with worsening chronic HF and reduced left ventricular ejection fraction (a measure of how well the left ventricle of the heart pumps with each beat) to receive placebo or 1 of 4 daily target doses of the medication vericiguat for 12 weeks.

Research reveals main reasons why people go to work when ill Posted: 09 Nov 2015 05:39 AM PST High job demands, stress and job insecurity are among the main reasons why people go to work when they are ill, according to new British research. The study aims to improve understanding of the key causes of employees going to work when sick, known as presenteeism, and to help make managers more aware of the existence of the growing phenomenon, what triggers the behavior and what can be done to improve employees' health and productivity.

Diagnosing and treating diabetes in heart attack patients improves heart outcomes Posted: 09 Nov 2015 05:39 AM PST People with heart problems often have diabetes, which puts them at greater risk for heart attacks, heart failure and stroke.

Watching cement dry could help dental fillings last longer Posted: 09 Nov 2015 05:34 AM PST Scientists have revealed 'sweet points' for dental fillings, where cement used to fill cracks regain elasticity before hardening indefinitely. This could have implications for creating more durable and longer-lasting fillings in the future.

Self-weighing may be a hazardous behavior among young women Posted: 09 Nov 2015 05:34 AM PST Self-weighing can be a useful tool to help adults control their weight, but for adolescents and young adults this behavior may have negative psychological outcomes. Researchers tracked the self-weighing behaviors of more than 1,900 young adults and found increases in self-weighing to be significantly related to increases in weight concern and depression and decreases in body satisfaction and self-esteem among females.
