Objectives:( 1) Evaluate the frequency of same-year, repeat concussions; (2) assess predictors of sustaining a repeat concussion; and (3) compare outcomes of athletes with repeat concussions with athletes with single concussion. Design: A retrospective, case–control study. Setting: Regional sports concussion center. Patients: Adolescents sustaining a sport-related concussions (SRC) from November 2017 to October 2020. Independent Variables: Participants were dichotomized into 2 groups: (1) athletes with a single concussion; and (2) athletes with repeat concussions. Main Outcome Measures: Betwee ..read more

Objectives: To examine factors associated with rates of game and practice-related concussion in youth ice hockey. Design: Five-year prospective cohort (Safe2Play). Setting: Community arenas (2013-2018). Participants: Four thousand eighteen male and 405 female ice hockey players (6584 player-seasons) participating in Under-13 (ages 11-12), Under-15 (ages 13-14), and Under-18 (ages 15-17) age groups. Assessment of Risk Factors: Bodychecking policy, age group, year of play, level of play, previous injury in the previous year, lifetime concussion history, sex, player weight, and playing position ..read more

Objective: To examine patient and injury factors that may predict quality of life (QoL) and symptom duration after concussion. Design: Prospective, longitudinal. Settings: Six children's hospital-based medical centers and 9 secondary school athletic training facilities. Patients: Pediatric patients (8-18 years) were enrolled as part of the Sport Concussion Outcomes in Pediatrics (SCOPE) study during their initial visit for a diagnosis of sport-related concussion. Interventions: Patients completed a medical history, the Postconcussion Symptom Inventory (PCSI), and Patient-Reported Outcomes Meas ..read more

Objective: Concussions are common match injuries in elite rugby, and reports exist of reduced cognitive function and long-term health consequences that can interrupt or end a playing career and produce continued ill health. The aim of this study was to investigate the association between elite rugby status and 8 concussion-associated risk polymorphisms. We hypothesized that concussion-associated risk genotypes and alleles would be underrepresented in elite rugby athletes compared with nonathletes. Design: A case–control genetic association study. Setting: Institutional (university). Participan ..read more

Objective: To determine the relationship between the female and male athlete triad with depression and anxiety symptoms. Design: Cross-sectional survey. Setting: Survey distributed online through social media to participants. Participants: Male and female high school, collegiate, and postcollegiate athletes. Interventions: Participants completed a survey assessing components of the female athlete triad and the Patient-Reported Outcomes Measurement Information System depression and anxiety short-form questionnaires. Main Outcome Measures: Participants were classified into those with no, mild, m ..read more

Abstract: Infectious mononucleosis (IM) is a common illness in children and young adults caused primarily by the Epstein–Barr Virus (EBV). Transmission occurs primarily through sharing oral secretions, thus IM is known as the “kissing disease.” Common clinical manifestations include fever, pharyngitis, posterior cervical lymphadenopathy, and splenomegaly. Atypical lymphocytosis and transaminase elevations are common, and the diagnosis of IM is confirmed with laboratory findings of a positive heterophile antibody (“Monospot”), polymerase chain reaction, or antibodies specific to EBV. Individual ..read more

Objective: We performed a systematic review and meta-analysis to evaluate the injury burden and the related economic cost in European professional male football players. Data Sources: Multiple database research was performed up to August 5, 2022 (PubMed, EMbase, Scopus, Cochrane Library), including only studies that reported severity in the number of days of absence for each injury, incidence reported in the number of injuries/1000 hours, or reported number of injuries and exposure time and adult male football players, professionals from European clubs. Two reviewers extracted data and assesse ..read more
