Breath test can monitor metabolism at home - study

Researchers at Anglia Ruskin University found that a portable breath test can detect changes in metabolism in response to diet. The study used the Lumen device to monitor metabolic fuel use at home and showed that it could detect acute changes in carbohydrate use, but was not sensitive on a day-to-day basis.

Bioindicator for the occurrence of PFAS

A comprehensive study found that wild boar liver can be used as a bioindicator for PFAS contamination in the environment, detecting hot-spots in regions with elevated PFAS levels. The researchers discovered that PFAS concentrations are highest in areas where industrial activities and agricultural practices have led to contamination.

New study finds unintentional weight loss often goes unrecognized by primary care physicians

A new study found that unintentional weight loss is grossly under-recognized in primary care, with only 21% recognized by doctors. The researchers recommend using electronic health record alerts to prompt clinicians to ask about intentional or unintentional weight loss, which can be a sign of a serious underlying condition.
