Dramatic Shift in Gut Microbes and Their Metabolites Seen After Weight Loss Surgery

141312_web.jpg

Obesity is linked with the composition of microbes in the human gut. In new research, bacterial composition in the gut, as well as accompanying metabolites are shown to undergo a profound and permanent shift, with microbial diversity significantly increasing following gastric bypass surgery.

Yearlong Survey Tracks the Microbiome of a Newly Opened Hospital

CCDexteriorcropped_3.jpg

A 12-month study mapping bacterial diversity within a hospital — with a focus on the flow of microbes between patients, staff and surfaces — should help hospitals worldwide better understand how to encourage beneficial microbial interactions and decrease potentially harmful contact. The Hospital Microbiome Project is the single biggest microbiome analysis of a hospital performed, and one of the largest microbiome studies ever.

First Study Shows Tie Between Probiotic and Improved Symptoms of Depression

It is the first study showing improved depression scores with a probiotic. It adds to the whole field of microbiota-gut-brain axis, providing evidence that bacteria affect behavior.

Switching to a Low-Glycemic Diet May Stop Age-Related Eye Disease, Study Suggests

Led by researchers at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University, a study in mice finds that development of age-related macular degeneration (AMD) could be arrested by switching from a high-glycemic to a low-glycemic diet.

Penn Study Finds Relationship Between Common Brain Disease and Gut Microbiome

KahnNatureCCMhumanbrainimageMay17.jpg

Bacteria in the gut microbiome drive the formation of cerebral cavernous malformations (CCMs), clusters of dilated, thin-walled blood vessels in the brain that can cause stroke and seizures. The research team’s research suggests that altering the microbiome in CCM patients may be an effective therapy for this cerebrovascular disease.

Controlling Bacteria’s Necessary Evil

IMG_1842.jpg

Until now, scientists have only had a murky understanding of how these relationships arise. Now Colin Dale and his colleagues at the University of Utah have an answer. It’s good news and bad news, germophobes: The bad news? Mutualistic bacteria start out by invading animal cells just like malevolent disease-causing bacteria do. The good news? Once they’re in, they calm down and play nice.

Study Shows Association Between Gut Microbes and Brain Structure in People with IBS

Research shows for the first time an association between the gut microbiota and the brain regions involved in the processing of sensory information from their bodies. Also, the researchers gained insight into the connections among childhood trauma, brain development and gut microbiome composition.

Prolonged Military-Style Training Causes Changes to Intestinal Bacteria, Increases Inflammation

A new study finds that long periods of physiological stress can change the composition of microorganisms residing in the intestines (intestinal microbiota), which could increase health risks in endurance athletes and military personnel. The study, published ahead of print in the American Journal of Physiology—Gastrointestinal and Liver Physiology, is the first to study the response of the intestinal microbiota during military training.
