Study reveals potential immune benefits of vitamin D supplements in healthy individuals

2013-03-21
(Press-News.org) (Boston) – Research from Boston University School of Medicine (BUSM) shows that improving vitamin D status by increasing its level in the blood could have a number of non-skeletal health benefits. The study, published online in PLOS ONE, reveals for the first time that improvement in the vitamin D status of healthy adults significantly impacts genes involved with a number of biologic pathways associated with cancer, cardiovascular disease (CVD), infectious diseases and autoimmune diseases. While previous studies have shown that vitamin D deficiency is associated with an increased risk for the aforementioned diseases, these results go a step further and provide direct evidence that improvement in vitamin D status plays a large role in improving immunity and lowering the risk for many diseases.

Vitamin D is unique in that it can be both ingested and synthesized by the body with sun exposure. It is then converted by both the liver and kidneys to a form that the body can use. An individuals' level of vitamin D, or their vitamin D status, is determined by measuring the level of 25-hydroxyvitamin D in the blood. Vitamin D deficiency, which is defined as a status of less than 20 nanograms per milliliter (ng/mL) of 25-hydroxyvitamin D, can cause a number of health issues, including rickets and other musculoskeletal diseases. Recently, however, data suggests that vitamin D deficiency ( END

Biodiversity does not reduce transmission of disease from animals to humans

2013-03-21
More than three quarters of new, emerging or re-emerging human diseases are caused by pathogens from animals, according to the World Health Organization. But a widely accepted theory of risk reduction for these pathogens – one of the most important ideas in disease ecology – is likely wrong, according to a new study co-authored by Stanford Woods Institute for the Environment Senior Fellow James Holland Jones and former Woods-affiliated ecologist Dan Salkeld. The dilution effect theorizes that disease risk for humans decreases as the variety of species in an area increases. ...

Sustainable Development Goals must sustain people and planet

2013-03-21
In the wake of last week's meetings at the UN on the definition of the Sustainable Development Goals (SDGs), a group of international scientists have published a call in the journal Nature today, arguing for a set of six SDGs that link poverty eradication to protection of Earth's life support. The researchers argue that in the face of increasing pressure on the planet's ability to support life, adherence to out-dated definitions of sustainable development threaten to reverse progress made in developing countries over past decades. Ending poverty and safeguarding Earth's ...

Baffling blood problem explained

Baffling blood problem explained
2013-03-21
In the early 1950's, a 66-year-old woman, sick with colon cancer, received a blood transfusion. Then, unexpectedly, she suffered a severe rejection of the transfused blood. Reporting on her case, the French medical journal Revue D'Hématologie identified her as, simply, "Patient Vel." After a previous transfusion, it turns out, Mrs. Vel had developed a potent antibody against some unknown molecule found on the red blood cells of most people in the world—but not found on her own red blood cells. But what was this molecule? Nobody could find it. A blood mystery began, ...

Media coverage of mass shootings contributes to negative attitudes towards mental illness

2013-03-21
News stories about mass shootings involving a shooter with mental illness heighten readers' negative attitudes toward persons with serious mental illness, according to a new report by the Johns Hopkins Bloomberg School of Public Health. The researchers also examined how such news stories impact support for policies to reduce gun violence. Compared to study respondents who did not read a story about a mass shooting, reading a news article describing a mass shooting raised readers' support for both gun restrictions for persons with serious mental illness, and for a ban on ...

Teen mentors inspire healthier choices in younger children

2013-03-21
COLUMBUS, Ohio – An obesity intervention taught by teen mentors in Appalachian elementary schools resulted in weight loss, lower blood pressure and healthy lifestyle changes among the younger students learning the curriculum, according to a new study. In contrast, children taught the same lessons by adults in a traditional classroom saw no changes in their health outcomes. The results of the eight-week clinical trial conducted by Ohio State University researchers suggest that school systems could consider using teen mentors to instruct younger children in select health-related ...

Charges for emergency room visits often based on incorrect assumptions

Charges for emergency room visits often based on incorrect assumptions
2013-03-21
Visits to the ER are not always for true medical emergencies – and some policymakers have been fighting the problem by denying or limiting payments if the patient's diagnosis upon discharge is for "nonemergency" conditions. Now a new UC San Francisco study challenges that framework by showing that criteria used as a basis to determine the appropriateness of an emergency room visit and to deny payment is inherently flawed. The study analyzed nearly 35,000 visits to hospital emergency departments around the country. The research is published online today in JAMA (Journal ...

NIH-supported researchers identify new class of malaria compounds

2013-03-21
A group of researchers from 16 institutions around the world has identified a new class of anti-malarial compounds that target multiple stages of the malaria parasite's life cycle (http://www.niaid.nih.gov/topics/malaria/pages/lifecycle.aspx). These compounds could potentially be developed into drugs that treat and prevent malaria infection. Known as 4-(1H)-quinolone-3-diarylethers, the candidate anti-malarials are derived from a compound called endochin that effectively treats malaria in birds. When tested in the laboratory and in mice, the compounds demonstrated strong ...

Brain mapping reveals neurological basis of decision-making in rats

Brain mapping reveals neurological basis of decision-making in rats
2013-03-21
Scientists at UC San Francisco have discovered how memory recall is linked to decision-making in rats, showing that measurable activity in one part of the brain occurs when rats in a maze are playing out memories that help them decide which way to turn. The more they play out these memories, the more likely they are to find their way correctly to the end of the maze. In their study, reported this week in the journal Neuron, the UCSF researchers implanted electrodes directly on a region of the rat brain known as the hippocampus, which is already known to play a key role ...

New imaging agent enables better cancer detection, more accurate staging

New imaging agent enables better cancer detection, more accurate staging
2013-03-21
Researchers at the University of California, San Diego School of Medicine have shown that a new imaging dye, designed and developed at UC San Diego Moores Cancer Center, is an effective agent in detecting and mapping cancers that have reached the lymph nodes. The radioactive dye called Technetium Tc-99m tilmanocept, successfully identified cancerous lymph nodes and did a better job of marking cancers than the current standard dye. Results of the Phase III clinical trial published online today in the Annals of Surgical Oncology. "Tilmanocept is a novel engineered radiopharmaceutical ...

Natural climate swings contribute more to increased monsoon rainfall than global warming

Natural climate swings contribute more to increased monsoon rainfall than global warming
2013-03-21
Monsoon rainfall in the Northern Hemisphere impacts about 60% of the World population in Southeast Asia, West Africa and North America. Given the possible impacts of global warming, solid predictions of monsoon rainfall for the next decades are important for infrastructure planning and sustainable economic development. Such predictions, however, are very complex because they require not only pinning down how manmade greenhouse gas emissions will impact the monsoons and monsoon rainfall, but also a knowledge of natural long-term climate swings, about which little is known ...
