Vitamin D levels linked to asthma severity. New research provides evidence for a link between vitamin D insufficiency and asthma severity. – Serum levels of vitamin D in more than 600 Costa Rican children were inversely linked to several indicators of allergy and asthma severity, including hospitalizations for asthma, use of inhaled steroids and total IgE levels.
Researchers recommends annual screening for vitamin D deficiency and routine vitamin D supplementation in at-risk populations, such as dark-skinned or veiled groups. – Annual screening for vitamin D deficiency and routine vitamin D supplementation in at-risk populations, such as dark-skinned or veiled groups, is recommended by Australian researchers.
Vitamin D deficiency may increase risk of colds, flu. Large-scale study supports potential role in boosting immune system. – Vitamin D may be an important way to arm the immune system against disorders like the common cold, report investigators from the University of Colorado Denver (UC Denver) School of Medicine, Massachusetts General Hospital (MGH) and Children’s Hospital Boston.
Genetic study shows direct link between vitamin D and MS susceptibility ‘gene’ – Researchers have found evidence that a direct interaction between vitamin D and a common genetic variant alters the risk of developing multiple sclerosis (MS).
Australian teens continue to put themselves at unnecessary risk of skin cancer by spending excessive time in the sun and forgetting to protect themselves. – Teens continue to put themselves at unnecessary risk of skin cancer by spending excessive time in the sun and forgetting to protect themselves, according to new Cancer Council research.
Taking calcium and vitamin D supplements does not lower a woman?s risk of breast cancer, according to a randomized controlled trial. – Taking calcium and vitamin D supplements does not reduce breast cancer incidence in postmenopausal women, according to data from a randomized, doubled-blind, placebo-controlled trial published online November 11 in the Journal of the National Cancer Institute.
County-level autism prevalence rates and counts among school-aged children were positively associated with a county’s mean annual precipitation. – Children living in counties with higher levels of annual precipitation appear more likely to have higher prevalence rates of autism, according to a report in the November issue of Archives of Pediatrics & Adolescent Medicine, one of the JAMA/Archives journals. The results raise the possibility that an environmental trigger for autism may be associated with precipitation and may affect genetically vulnerable children.
Mother’s vitamin D status during pregnancy will affect her baby’s dental health, leading to enamel defects, which are a risk factor for early-childhood tooth decay. – Low maternal vitamin D levels during pregnancy may affect primary tooth calcification, leading to enamel defects, which are a risk factor for early-childhood tooth decay.
Vitamin D deficiency is associated with incident cardiovascular disease. Further clinical and experimental studies may be warranted to determine whether correction of vitamin D deficiency could contribute to the prevention of cardiovascular disease. – The same vitamin D deficiency that can result in weak bones now has been associated with an increased risk of cardiovascular disease, Framingham Heart Study researchers report in Circulation: Journal of the American Heart Association.
Professor John Kappelman of The University of Texas at Austin reveals the most ancient evidence of the tuberculosis disease has been found in a 500,000-year-old human fossil from Turkey.
– Although most scientists believe tuberculosis emerged only several thousand years ago, new research from The University of Texas at Austin reveals the most ancient evidence of the disease has been found in a 500,000-year-old human fossil from Turkey.
