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.
