As the COVID-19 pandemic emerged, skin manifestations have been reported as part of this disease's multisystem manifestations. While a rash similar to chilblains in acral distribution has been the most commonly reported complication, we noted a pattern of more severe lower extremity skin complications, specifically large bullae, in a series of COVID-19 patients.

Objectives: Our objective was to determine risk factors and operative outcomes for patients with upper extremity penetrating vascular injuries(UEPVI).
Methods: A retrospective review was performed of all adult UEPVI patients presenting to a level I trauma center between 1986 and 2019. Statistical analyses were performed to determine the independent predictors of mortality and hospital length of stay(LOS) among patients who underwent operative repair.

Objectives: To investigate whether baseline depressive symptoms impacted the effectiveness of an exercise intervention among (pre)frail older adults.
Methods: This is a subanalysis of a stepped-wedge cluster randomized trial implementing an exercise intervention, with an application of the integration of the Health Belief Model, Theory of Planned Behavior, and Health Action Process Approach, among 149 community-dwelling (pre)frail older adults. The intervention effectiveness was examined by baseline depressive symptoms (depressive symptoms ( = 40) and non-depressive symptoms ( = 109).

Many children with cerebral palsy (CP) are frail and require major hip and/or spine surgeries associated with substantial blood loss. Tranexamic acid (TXA) is commonly used to reduce blood loss, but there is uncertainty around the optimal dose and timing of administration. There have been reviews in sub-populations and specific dosing regimens, but a broad overview of the available literature is lacking.

Background: INTER- and INTRAmuscular fat (IMF) is elevated in high metabolic states and can promote inflammation. While magnetic resonance imaging (MRI) excels in depicting IMF, the lack of reproducible tools prevents the ability to measure change and track intervention success.
Methods: We detail an open-source fully-automated iterative threshold-seeking algorithm (ITSA) for segmenting IMF from T1-weighted MRI of the calf and thigh within three cohorts (CaMos Hamilton (N = 54), AMBERS (N = 280), OAI (N = 105)) selecting adults 45-85 years of age.

We compared the force-velocity (F-V) characteristics between jump squat (JS) and weightlifting (hang clean [HC] and HC pull [HCP]) to determine lower limb F-V portions targeted by weightlifting exercises. Ten weightlifters performed JS at 0% (body weight only) to 70% of their one-repetition maximum (1RM) for back squat, and HC and HCP at 30‒90% and 30‒110% of their 1RM for HC, respectively. Force and velocity values at each relative load were plotted to determine the F-V features of JS, HC, and HCP.
