Associations of Sex and Sport Contact-Level with Recovery Timelines Among Collegiate Athletes with Sport-Related Concussion.

Background: Growing interest has motivated recent studies to examine differences in recovery after sport-related concussion (SRC) by sex. However, heterogeneity in study design, participants, and recovery outcomes has led to mixed findings. Further work is needed to evaluate potential differences by sex and to investigate the role of related characteristics, such as sport contact-level, in recovery timelines.

Publicly available data sources in sport-related concussion research: a caution for missing data.

Background: Researchers often use publicly available data sources to describe injuries occurring in professional athletes, developing and testing hypotheses regarding athletic-related injury. It is reasonable to question whether publicly available data sources accurately indicate athletic-related injuries resulting from professional sport participation. We compared sport-related concussion (SRC) clinical incidence using data from publicly available sources to a recent publication reporting SRC using electronic health records (EHR) from the National Football League (NFL).

A Randomized Trial of Incentivization to Maximize Retention for Real-Time Symptom and Activity Monitoring Using Ecological Momentary Assessment in Pediatric Concussion.

Objective: The aims of this study were to determine the incentivization strategy that maximizes patient adherence to report symptoms and activity via ecological momentary assessment (EMA) after pediatric concussion, and assess the feasibility of tracking concussed youth using EMA from the emergency department (ED) setting.

Methods: This study was a randomized controlled trial of participants ages 13 to 18 years with concussion presenting to an urban, academic pediatric ED within 5 days of injury. Participants were randomized to 1 of 4 incentive arms: 2 dynamic (loss-based and streak) and 2 control flat-rate (monetary and electronic device).

The Role of Reported Affective Symptoms and Anxiety in Recovery Trajectories After Sport-Related Concussion.

Background: There is growing awareness and clinical interest in athletes with affective symptoms after sport-related concussion (SRC), as these symptoms may contribute to overall symptoms and represent a modifiable risk factor of longer recovery. However, evidence of their effects on the entire return-to-play (RTP) trajectory, particularly among women and men, is limited.

Purpose/hypothesis: To examine the relationship between affective symptom reporting and RTP progression after SRC among a cohort of Division 1 student-athletes.

Progression through return-to-sport and return-to-academics guidelines for concussion management and recovery in collegiate student athletes: findings from the Ivy League-Big Ten Epidemiology of Concussion Study.

Objective: To examine the progression of collegiate student athletes through five stages of a return-to-activity protocol following sport-related concussion (SRC).

Methods: In a multisite prospective cohort study, we identified the frequency of initial 24-48 hours physical and cognitive rest, and the sequence of (1) symptom resolution and return to (2) exertion activity, (3) limited sport, (4) full sport and (5) full academics. In resulting profiles we estimated the likelihood of return to full sport ≤14 days or prolonged >28 days and tested for variability based on timing of the stages.

Design and Evaluation of a Postpartum Depression Ontology.

Objective: Postpartum depression (PPD) remains an understudied research area despite its high prevalence. The goal of this study is to develop an ontology to aid in the identification of patients with PPD and to enable future analyses with electronic health record (EHR) data.

Methods: We used Protégé-OWL to construct a postpartum depression ontology (PDO) of relevant comorbidities, symptoms, treatments, and other items pertinent to the study and treatment of PPD.

Sex difference in association between insomnia and cognitive impairment in patients with chronic schizophrenia.

Objective: Sex differences in schizophrenia have been noted across domains such as sleep and cognitive function； however, how they interact remains unclear. This study aimed to explore sex differences in the relationship between insomnia and cognitive function in patients with chronic schizophrenia.

Methods: 718 schizophrenia patients (480 males and 238 females) and 397 healthy controls were recruited.

Proptosis masquerading as buphthalmos following glaucoma drainage device surgery in a child with congenital glaucoma.

Glaucoma drainage devices are commonly used in the surgical treatment of children with glaucoma. We report a case of unusually large reservoir formation causing proptosis, exposure keratopathy, and motility deficits. This case highlights the importance of B-scan and axial length measurements in differentiating proptosis from buphthalmos in children with glaucoma.

Public Libraries As Partners for Health.

Introduction: Public libraries are free and accessible to all and are centers of community engagement and education, making them logical choices as partners for improving population health. Library staff members routinely assist patrons with unmet health and social needs.

Methods: We used a 100-question, self-administered web survey sent to all library directors listed in the Pennsylvania Library Association database (N = 621), to investigate staff interactions with library patrons to address social determinants of health.

Violence in Rural, Suburban, and Urban Schools in Pennsylvania.

School violence is a public health issue with direct and collateral consequences that has academic and social impacts for youth. School violence is often considered a uniquely urban problem, yet more research is needed to understand how violence in rural and suburban schools may be similar or different from urban counterparts. Using school violence data from a state with urban, suburban, and rural counties, we explored the landscape of school violence in Pennsylvania (PA) through mapping, descriptive statistics, and factor analysis.
