Some of the things you will hear Dr. Buttar and Robert talk about in this week’s show are:
Autism is associated with zinc deficiency in early development—now a study links the two – The emergence of autism in children has not only been linked to genes encoding synaptic proteins—among others—but also environmental insults such as zinc deficiency. Although it is unclear whether zinc deficiency contributes to autism, scientists have now defined in detail a possible mechanistic link. Their research shows how zinc shapes the connections or ‘synapses’ between brain cells that form during early development, via a complex molecular machinery encoded by autism risk genes. Published in Frontiers in Molecular Neuroscience, the findings do not directly support zinc supplementation for the prevention of autism—but extend our understanding of its underlying developmental abnormalities, towards an eventual treatment.
Fat-clogged cells explain why obesity can cause cancer – A type of cell the body uses to destroy cancerous tissue gets clogged by fat and stops working, the team, from Trinity College Dublin, found. Obesity is the biggest preventable cause of cancer in the UK after smoking, Cancer Research UK says. And more than one in 20 cancer cases – about 22,800 cases each year in the UK – are caused by excess body weight. Experts already suspected fat sent signals to the body that could both damage cells, leading to cancer, and increase the number of them. Now, the Trinity scientists have been able to show, in Nature Immunology journal, how the body’s cancer-fighting cells get clogged by fat. And they hope to be able to find drug treatments that could restore these “natural killer” cells’ fighting abilities.
Coronary calcium levels a better predictor of patients at risk for coronary heart disease – A new study presented at the American Heart Association Scientific Session conference found that testing a patient’s coronary calcium levels is a better predictor of blocked coronary arteries at risk for a heart attack and the need for revascularization than standard risk-assessment equations used in medical practice today. “With coronary calcium, we’re looking at a marker indicating the actual presence of anatomic disease—we’re not just looking at probabilities of disease based on a patient’s standard risk factors,” said Jeffrey L. Anderson, MD, a cardiologist and cardiovascular researcher at the Intermountain Medical Center Heart Institute in Salt Lake City. “The risk factors are worth knowing, but they don’t tell whether or not you actually have the disease.” Cardiovascular disease remains the greatest cause of morbidity and mortality in the United States, and determining who’s most at risk continues to be suboptimal, said Dr. Anderson.
