Prospective arrhythmia surveillance after a COVID-19 diagnosis.

Background: Cardiac arrhythmias have been observed among patients hospitalised with acute COVID-19 infection, and palpitations remain a common symptom among the much larger outpatient population of COVID-19 survivors in the convalescent stage of the disease.

Objective: To determine arrhythmia prevalence among outpatients after a COVID-19 diagnosis.

Methods: Adults with a positive COVID-19 test and without a history of arrhythmia were prospectively evaluated with 14-day ambulatory electrocardiographic monitoring.

Barriers and Facilitators to Behavior Change for Individuals with Severe Mental Illness who Received the Transdiagnostic Intervention for Sleep and Circadian Dysfunction in a Community Mental Health Setting.

The Transdiagnostic Intervention for Sleep and Circadian Dysfunction (TranS-C) was implemented in a community mental health center (CMHC) setting. The goal of TranS-C is to improve sleep and circadian dysfunction among people with severe mental illness. The present study uses the Theoretical Domains Framework (TDF) to uncover barriers and facilitators to changing behaviors learned in TranS-C.

Predictors of incident SARS-CoV-2 infections in an international prospective cohort study.

Objective: Until effective treatments and vaccines are made readily and widely available, preventative behavioural health measures will be central to the SARS-CoV-2 public health response. While current recommendations are grounded in general infectious disease prevention practices, it is still not entirely understood which particular behaviours or exposures meaningfully affect one's own risk of incident SARS-CoV-2 infection. Our objective is to identify individual-level factors associated with one's personal risk of contracting SARS-CoV-2.
