Risk for Reinfection After SARS-CoV-2: A Living, Rapid Review for American College of Physicians Practice Points on the Role of the Antibody Response in Conferring Immunity Following SARS-CoV-2 Infection.

Background: The strength and duration of immunity from infection with SARS-CoV-2 are important for public health planning and clinical practice.

Purpose: To synthesize evidence on protection against reinfection after SARS-CoV-2 infection.

Data Sources: MEDLINE (Ovid), the World Health Organization global literature database, ClinicalTrials.

Antibody Response After SARS-CoV-2 Infection and Implications for Immunity : A Rapid Living Review.

Background: The clinical significance of the antibody response after SARS-CoV-2 infection remains unclear.

Purpose: To synthesize evidence on the prevalence, levels, and durability of detectable antibodies after SARS-CoV-2 infection and whether antibodies to SARS-CoV-2 confer natural immunity.

Data Sources: MEDLINE (Ovid), Embase, CINAHL, Cochrane Central Register of Controlled Trials, ClinicalTrials.

Retention Strategies for Medications for Opioid Use Disorder in Adults: A Rapid Evidence Review.

Objectives: Although medications for opioid use disorder (MOUD) save lives, treatment retention remains challenging. Identification of interventions to improve MOUD retention is of interest to policymakers and researchers. On behalf of the Agency for Healthcare Research and Quality, we conducted a rapid evidence review on interventions to improve MOUD retention.

His-bundle pacing versus biventricular pacing in cardiac resynchronization therapy patients: A crossover design comparison.

Background: Cardiac resynchronization therapy (CRT) typically is attempted with biventricular pacing (BiVP). One-third of patients are nonresponders. His-bundle pacing (HBP) has been evaluated as an alternative means of effecting CRT because it generates truly physiologic ventricular activation, as evidenced in part by the morphologic identity between normally conducted and paced QRS complexes.
