Watchman FLX Next Gen Stroke Prevention Device Now FDA Approved

Boston Scientific’s WATCHMAN, a device that’s used to close the left atrial appendage, has done wonders for preventing the formation of clots that lead to stroke in many patients. Now the company has announced that its WATCHMAN FLX, a new and much improved version of the implant, won FDA approval. Already cleared in the European Union, the WATCHMAN FLX is indicated for patients with non-valvular atrial fibrillation (NVAF) for whom oral anticoagulants are not sufficient. The...

Spinal Cord Stimulators Give Robotic Prostheses a Sense of Touch

00:25

Upper arm prostheses that give their users a sense of touch have been developed in the past (see flashbacks below). These require careful surgical placement of electrodes near the remaining nerves within the stump and precise stimulation of said nerves. Now researchers at the University of Pittsburgh have achieved a remarkable feat of using existing spinal cord stimulators, usually used to treat chronic pain, to produce a sense of touch in the missing limbs of amputees. This can certainly...

Nanogenerators Harvest Energy from Body, Monitor Heart Health

Wed Jul 22, 2020 22:45

Wearable medical devices such as continuous heart rate monitors, insulin pumps, and neural stimulators usually need access to an electric power source in order to function. While there’s a great deal of wasted energy that our body emits that can be harvested to power such devices, making it actually happen using biocompatible materials has proven to be challenging. Now, a team of engineers at Purdue University has shown that polyvinyl alcohol (PVA), one of the most common polymers used in...

Investigating Validity and Reliability of the Turkish Version of Transsexual Voice Questionnaire (Male to Female)

The problems faced by trans women with regard to their voice may affect their quality of life. For the evaluation of trans women's voice, tools assessing their self-perception are very important, with the Transsexual Voice Questionnaire (TVQMtF ) being one of the most frequently used. The purpose of this study was to investigate the validity and reliability of the Turkish version of the TVQMtF (TVQMtF –TR), which was previously translated into 12 languages.

Neuroradiology

Abstract Purpose Spinal cord involvement in Kearns-Sayre (KSS) syndrome could be more frequent than commonly thought. Our aims were to evaluate the involvement of the spinal cord in patients with KSS by means of MRI and to investigate possible correlations of spinal and brain disease with patient disability. Methods Eleven patients with KSS disease...

Microstructural damage of the cortico-striatal and thalamo-cortical fibers in Fabry disease: a diffusion MRI tractometry study

Abstract Purpose Recent evidences have suggested the possible presence of an involvement of the extrapyramidal system in Fabry disease (FD), a rare X-linked lysosomal storage disorder. We aimed to investigate the microstructural integrity of the main tracts of the cortico-striatal-thalamo-cortical loop in FD patients. Methods Forty-seven FD patients...

Ultra-small, parasitic bacteria found in groundwater, moose – and you

Inside your mouth lives a group of bacteria whose closest relatives can also be found in the belly of a moose, in dogs, cats, and dolphins, and in groundwater deep under the Earth’s surface. In a noteworthy discovery, scientists led by a UW School of Dentistry researcher have found that these organisms have adapted to these incredibly diverse environments without radically changing their genetic makeup, or genomes. The post Ultra-small, parasitic bacteria found in groundwater, moose – and you...
