New research identifies link between gut microbes and stroke

New findings from Cleveland Clinic researchers show for the first time that the gut microbiome impacts stroke severity and functional impairment following stroke. The results, published in Cell Host & Microbe, lay the groundwork for potential new interventions to help treat or prevent stroke.

The research was led by Weifei Zhu, Ph.D., and Stanley Hazen, M.D., Ph.D., of Cleveland Clinic's Lerner Research Institute. The study builds on more than a decade of research spearheaded by Dr. Hazen and his team related to the gut microbiome's role in cardiovascular health and disease, including the adverse effects of TMAO (trimethylamine N-oxide)—a byproduct produced when gut bacteria digest certain nutrients abundant in red meat and other animal products.

Wearable ultrasound patch could warn of cardiovascular problems
By Ben Coxworth
July 23, 2021

It goes without saying that the earlier someone can be warned of an impending heart attack or stroke, the better. A new skin patch could provide such warnings, by sending ultrasound pulses into the wearer's body.

Building upon a previously developed device, the patch was created at the University of California-San Diego by a team led by Prof. Sheng Xu. Worn on the neck or chest, it consists of a thin sheet of flexible, stretchable polymer, inside of which is a 12 by 12 grid of millimeter-sized ultrasound transducers. The patch is currently hard-wired to a computer and power source, but plans call for it to ultimately be self-contained and wireless.

In one operational mode, all of the transducers can be set to transmit ultrasound wave pulses at the same time. This produces an ultrasound beam that focuses directly down onto one area of the body, up to 14 cm (5.5 in) beneath the skin.

In the other mode, the transducers transmit their waves out of sync with one another, but still rapidly enough that they form one cohesive beam. In this case, however, that beam can be pointed in different angles, as opposed to just straight down from the patch. This means that different areas could be scanned without having to stick the patch right above each one.
