Relapse of concussion symptoms in the context of premature return to learn and return to play: Comparative analysis of 2006 to 2011 and 2011 to 2016.

Objective: To determine whether the proportion of sport-related concussion (SRC) cases among student athletes that resulted in a relapse of their symptoms due to premature return to play (RTP) or premature return to learn (RTL) has changed compared with a prior (2006 to 2011) study.

Design: Retrospective cohort study of electronic medical record charts from a 5-year period (2011 to 2016) compared with previous data.

Setting: A sport and exercise medicine physician's office-based practice in Ontario.

Acute Hemorrhagic Encephalitis Related to COVID-19.

Purpose Of Review: The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the most critical public health challenge in recent history. In this report, we present a case of suspected acute hemorrhagic encephalitis with bilateral intracranial hemorrhages associated with coronavirus disease 2019 (COVID-19) infection.

Recent Findings: A 48-year-old female COVID-19-positive patient developed acute changes in her neurologic status.

The effects of obstacle proximity on aperture crossing behaviours.

Affordance theory and behavioural dynamics have been used as theoretical constructs to explain how individuals interact with the environment in order to avoid obstacles. Features of obstacle distance and multiple obstacle avoidance have been discussed in unique studies, yet the interactions of these environmental features have yet to be explored. The purpose of this study was to asses the effects of obstacle distance, relative to the goal, on aperture crossing strategies.

Visuomotor deficits during locomotion in previously concussed athletes 30 or more days following return to play.

Current protocols for returning athletes to play (RTP) center around resolution of physical symptoms of concussion. However, recent research has identified that balance and cognitive deficits persist beyond physical symptom recovery. Protocols that involve testing dynamic balance and visuomotor integration have been recommended as potential tools for better understanding of length of impairment following concussion.

Perspective on reconstruction after mastectomy.

Background: We sought to evaluate the factors influencing our patients to receive or forego reconstruction after mastectomy and their subsequent satisfaction with their decision.

Methods: A questionnaire was sent to 819 patients who underwent mastectomy from 1994 to 1998 in a community-based health system.

Results: Response rate was 50% (408 of 819).
