Fatal Exertional Heat Stroke Trends in Secondary School Sports From 1982 Through 2022.

Background: Exertional heat stroke (EHS) is a leading cause of secondary school sport-related death; however, a longitudinal analysis on observed trends is lacking. Our purpose was to describe EHS deaths in United States secondary school athletes since the 1982/1983 academic year.

Hypothesis: EHS deaths will be primarily represented by football athletes and have a stable or increasing trend across a decade-by-decade analysis.

Olfactory function is reduced in a subset of former elite American football players with traumatic encephalopathy syndrome.

Former American football players are at risk for developing traumatic encephalopathy syndrome (TES), the clinical disorder associated with neuropathologically diagnosed chronic traumatic encephalopathy (CTE). The objective of this study was to determine whether hyposmia is present in traumatic encephalopathy syndrome. The study included 119 former professional American football players, 60 former college football players, and 58 same-age asymptomatic unexposed men from the DIAGNOSE CTE Research Project.

Duration of Ice Hockey Play and Chronic Traumatic Encephalopathy.

Importance: Chronic traumatic encephalopathy (CTE) is a neurodegenerative tauopathy associated with repetitive head impacts (RHIs). Prior research suggests a dose-response association between American football play duration and CTE risk and severity, but this association has not been studied for ice hockey.

Objective: To investigate associations of duration of ice hockey play with CTE diagnosis and severity, functional status, and dementia.

Spontaneous Headshake after a Kinematic Event (SHAAKE): Evaluating the Utility of a Potential New Sign in the Diagnosis of Concussion.

: Diagnosing concussions is problematic, in part due to the invisible nature of concussion symptoms, in addition to personal and interpersonal factors that influence symptom reporting. As a result, observable signs of concussion can ensure concussions are identified and appropriately treated. Here, we define a potential novel sign, the spontaneous headshake after a kinematic event (SHAAKE) and evaluate its utility in the diagnosis of concussion.

Variability in youth coach concussion education requirements across states.

Background: Youth sports coaches play a critical role in proper concussion recognition and management, reinforcing the need for coach concussion education. As of 2021, most states have statutory and policy measures mandating concussion education for coaches. In practice, these mandates have been enacted through state legislatures and their respective youth sport governing bodies.

Younger and rural children are more likely to be hospitalized for SARS-CoV-2 infections.

Purpose: To identify characteristics of SARS-CoV-2 infection that are associated with hospitalization in children initially evaluated in a Pediatric Emergency Department (ED).

Methods: We identified cases of SARS-CoV-2 positive patients seen in the Arkansas Children's Hospital (ACH) ED or hospitalized between May 27, 2020, and April 28, 2022, using ICD-10 codes within the Pediatric Hospital Information System (PHIS) Database. We compared infection waves for differences in patient characteristics and used logistic regressions to examine which features led to a higher chance of hospitalization.

Incidents and patterns of among athletes in the USA from 1982 to 2023.

Introduction: is a rare event that occurs following blunt, non-penetrating trauma to the chest, precipitating a ventricular arrhythmia. requires immediate medical attention through cardiopulmonary resuscitation and defibrillation, often resulting in death. is most common condition among young male athletes.

Wetsuit Thermal Resistivity Measurements.

In recent years, attention to the realization and characterization of wetsuits for scuba diving and other sea sports or activities has increased. The research has aimed to establish reliable and standardized measurement methods to objectively assess wetsuit quality, particularly focusing on their mechanical and thermal properties. In this work, we describe and compare two different measurement methods for the characterization of neoprene wetsuit thermal resistivity.

Lack of Association of Informant-Reported Traumatic Brain Injury and Chronic Traumatic Encephalopathy.

Repetitive head impacts (RHIs) from football are associated with the neurodegenerative tauopathy chronic traumatic encephalopathy (CTE). It is unclear whether a history of traumatic brain injury (TBI) is sufficient to precipitate CTE neuropathology. We examined the association between TBI and CTE neuropathology in 580 deceased individuals exposed to RHIs from football.

Catastrophic injuries and exertional medical events in lacrosse among youth, high school and collegiate athletes: longitudinal surveillance over four decades (1982-2020).

Objective: To determine the incidence rates (IRs) of catastrophic injuries and exertional medical events in lacrosse athletes.

Methods: Catastrophic injuries and exertional medical events in lacrosse in the US among youth or amateur, high school and college athletes were analysed from the National Center for Catastrophic Sport Injury Research (NCCSIR) database from 1982/83 to 2019/20. Frequencies, IRs per 100,000 athlete-seasons (AS) with 95% confidence intervals (CIs), and incidence rate ratios (IRRs) with 95% CIs were calculated.

Impact of Preferred Written Language in Patients Discharged With Bronchiolitis From a Children's Hospital.

Objectives: This study aimed to identify differences in length of stay and readmission in patients admitted with bronchiolitis based on preferred written language. A secondary aim was to assess adherence to providing written discharge instructions in patients' preferred language.

Methods: In this cross-sectional study, we included 384 patients aged 0 to 2 years discharged from 2 children's hospitals with bronchiolitis from May 1, 2021, through April 30, 2022; patients were excluded for history of prematurity, complex chronic condition, or ICU stay during the study period.

Cognitive, functional, and neuropsychiatric correlates of regional tau pathology in autopsy-confirmed chronic traumatic encephalopathy.

Background: Chronic traumatic encephalopathy (CTE) is a neurodegenerative disease characterized by hyperphosphorylated tau (p-tau) accumulation. The clinical features associated with CTE pathology are unclear. In brain donors with autopsy-confirmed CTE, we investigated the association of CTE p-tau pathology density and location with cognitive, functional, and neuropsychiatric symptoms.

Association of Vascular Risk Factors and CSF and Imaging Biomarkers With White Matter Hyperintensities in Former American Football Players.

Background And Objectives: Recent data link exposure to repetitive head impacts (RHIs) from American football with increased white matter hyperintensity (WMH) burden. WMH might have unique characteristics in the context of RHI beyond vascular risk and normal aging processes. We evaluated biological correlates of WMH in former American football players, including markers of amyloid, tau, inflammation, axonal injury, neurodegeneration, and vascular health.

Amsterdam 2022 process: A summary of the methodology for the Amsterdam International Consensus on Concussion in Sport.

The purpose of this paper is to summarise the consensus methodology that was used to inform the International Consensus Statement on Concussion in Sport (Amsterdam 2022). Building on a Delphi process to inform the questions and outcomes from the 5th International Conference on Concussion in Sport, the Scientific Committee identified key questions, the answers to which would help encapsulate the current science in sport-related concussion and help guide clinical practice. Over 3½ years, delayed by 2 years due to the pandemic, author groups conducted systematic reviews on each selected topic.
