Postural orthostatic tachycardia syndrome after COVID-19 vaccination.

Background: There is an association between coronavirus disease 2019 (COVID-19) mRNA vaccination and the incidence or exacerbation of postural orthostatic tachycardia syndrome (POTS).

Objective: The purpose of this study was to characterize patients reporting new or exacerbated POTS after receiving the mRNA COVID-19 vaccine.

Methods: We prospectively collected data from sequential patients in a POTS clinic between July 2021 and June 2022 reporting new or exacerbated POTS symptoms after COVID-19 vaccination.

Moving toward point-of-care surgery in Ukraine: testing an ultra-portable operating room in an active war zone.

Purpose: In conflict zones, providers may have to decide between delaying time-sensitive surgeries or performing operative interventions in the field, potentially subjecting patients to significant infection risks. We conducted a single-arm crossover study to assess the feasibility of using an ultraportable operating room (U-OR) for surgical procedures on a porcine cadaver abdominal traumatic injury model in an active war zone.

Methods: We enrolled participants from an ASSET-type course designed to train Ukrainian surgeons before deployment to active conflict zones.
