Our knowledge in the field of sleep disorders in older adults has increased in recent years, yet some groups within this heterogeneous population, such as frail older adults, remain to be more thoroughly studied and characterized.

Despite sex differences in the clinical incidence of SRCs and time loss from participation in high school sports, the numbers of missed school days are relatively similar between sexes.

Context The sex-based differences in the structure and rules of boys' and girls' lacrosse result in very different styles of play, which may have significant implications for the rates and patterns of injuries. Objective To compare the epidemiology of injuries sustained by boys' and girls' lacrosse players. Design Descriptive epidemiology study. Setting Web-based online surveillance system. Patients or Other Participants The High School Reporting Information Online database was used to analyze injuries reported by certified athletic trainers from 2008–2009 through 2015–2016. Main Outcome Measure(s) Practice and competition injury rates, body site, diagnosis, and mechanism. Results Boys had a higher injury rate than girls (20.9 versus 15.7 per 10 000 athlete-exposures, respectively; rate ratio = 1.3, 95% confidence interval = 1.2, 1.4). The most commonly injured body sites for boys and girls, respectively, were the lower extremities (38.0%, 56.4%) and the head/neck (28.3%, 29.8%). More specifically, the most frequently diagnosed injuries for both boys and girls, respectively, in competitions were concussions (23.1%, 25.6%), ankle ligament sprains (7.8%, 15.3%), upper leg strains (4.8%, 6.7%), and knee ligament sprains (4.2%, 6.7%). The most cited mechanism of injury overall was contact with another player (22.0%); among boys, it was contact with a stick (14.8%) and among girls, the most frequent mechanisms were overuse (25.0%) and contact with a stick (14.7%). Conclusions Injury rates and mechanisms of injuries differed between high school boys' and girls' lacrosse players. Boys had a higher rate of injury, with the most common mechanism of injury being contact with another player compared with overuse in girls. However, similarities were seen between sexes for the most frequently injured body sites and injury diagnoses. Future authors should continue to compare differences in injury rates, equipment upgrades, and rule changes in boys' and girls' lacrosse.

Context: Vestibular and ocular motor assessment is an emerging clinical assessment for sport-related concussion (SRC). The increased use of these assessments by clinicians calls for examination of outcomes in populations that may impact clinical practice. Objective: Compare vestibular and ocular motor impairments in high school and collegiate athletes within 72 hours of SRC. Second, examine the distribution of impairments in these populations based upon pre-established clinical cut-off scores. Design: Cross-sectional study. Setting: High school (HS) and collegiate athletics (COL). Patient or Other Participants: Data were collected from 110 athletes (HS: n=47, age=15.40±1.35 years; COL: n=63, age=19.46±1.28 years) within 72 hours of sustained SRC. Main Outcome Measure(s): Total and change scores were calculated for the Vestibular/Ocular Motor Screening (VOMS) assessment, along with average near point of convergence (NPC) distance. Separate Mann Whitney U tests were used to compare group differences and Chi-square analyses were used to examine athlete distribution above clinical cutoff scores for all VOMS outputs (a priori Alpha level<0.5). Results: No significant differences were found between high school and collegiate athletes for VOMS total scores, change scores, and NPC distance. A significantly larger proportion of the sample reported scores above the cutoff for all total scores (p<0.001) and change scores in horizontal vestibulo-ocular reflex (VOR; 59.01%, p<0.001), vertical VOR (60.91%, p<0.001), and visual motion sensitivity (60.91%, p<0.001). However, a significantly larger proportion reported smooth pursuit change scores (85.45%, p<0.001) and NPC distance (73.64%, p=0.01) below the cutoff scores. Conclusions: During the acute phase of SRC, high school and collegiate athletes present with similar vestibular and ocular motor impairments as measured by the VOMS, but vestibular tasks appear to cause greater symptom provocation in concussed athletes. Lastly, VOMS change scores may offer more clinical utility in assessing specific impairments following SRC compared to total scores.
