Exosome based analysis for Space Associated Neuro-Ocular Syndrome and health risks in space exploration.

Molecular profiling to characterize the effects of environmental exposures is important from the human health and performance as well as the occupational medicine perspective in space exploration. We have developed a novel exosome-based platform that allows profiling of biological processes in the body from a variety of body fluids. The technology is suitable for diagnostic applications as well as studying the pathophysiology of the Space Associated Neuro-Ocular Syndrome in astronauts and monitoring patients with chronically impaired cerebrospinal fluid drainage or elevated intracranial pressure.

Early Experience With Interleukin-6 Receptor Antagonists in Patients With COVID-19 Admitted to a Community Hospital.

The efficacy of interleukin-6 (IL-6) inhibitors in hospitalized patients with severe coronavirus disease 2019 (COVID-19) pneumonitis is unclear. This retrospective, observational cohort study included patients hospitalized at a community hospital with COVID-19 pneumonia from March 2020 to May 2020. All patients were treated with standard of care (SOC), and a nonrandomly selected subset of patients also received an IL-6 inhibitor.

Evaluating the Safety of Trough Versus Area Under the Curve (AUC)-Based Dosing Method of Vancomycin With Concomitant Piperacillin-Tazobactam.

Vancomycin and piperacillin-tazobactam (VPT) is a common antibiotic combination used in hospitals, and there has been increasing data indicating that the combination is associated with increased rates of acute kidney injury (AKI). It is unclear if the dosing method of vancomycin would mitigate the risk of AKI seen with VPT. : To observe and compare incidence of AKI in patients on VPT when using the trough-based dosing method versus the area-under-the-curve (AUC)-based dosing method.
