Effect of surgeon volume on pediatric thyroid surgery outcomes: A systematic review.

Background: Pediatric thyroidectomy has been identified as a surgical procedure that may benefit from concentrating cases to high-volume surgeons. This systematic review aimed to address the definition of "high-volume surgeon" for pediatric thyroidectomy and to examine the relationship between surgeon volume and outcomes.

Methods: PubMed, Embase, Cochrane Library, Scopus, Web of Science, ClinicalTrials.

Safety of maximal cardiopulmonary exercise testing in individuals with sickle cell disease: a systematic review.

Objective: We evaluated the safety of maximal cardiopulmonary exercise testing (CPET) in individuals with sickle cell disease (SCD). Maximal CPET using gas exchange analysis is the gold standard for measuring cardiopulmonary fitness in the laboratory, yet its safety in the SCD population is unclear.

Design: Systematic review.
