s that naturally manifest secondary structures. Our studies demonstrate the retention of distinct architectures after complex assembly, a paradigm that we believe may extend to other polymeric folding systems.
The purpose of the current study was to explore knowledge surrounding sport-related concussions (SRCs) and the impact on reporting behaviors in collegiate athletes, including sex differences.
Cross-sectional.
Institutional.
Participants were 986 collegiate athletes (607 men), aged 19.7 years (SD = 1.4) from 6 institutions, who completed a survey, including items on personal/sport demographics and SRC knowledge and reporting behaviors.
Athletes were given a short (15-minute) survey to complete during team meetings and preparticipation physicals.
Athletes' scores on the survey, and reporting behaviors (ie, whether or not they failed to report a suspected SRC and reasons for not reporting SRCs), were examined.
Independent samples t tests revealed female athletes scored significantly higher than male athletes on total SRC knowledge [t (926.6) = -10.6, P < 0.01] and symptom knowledge (t (859) = -7.0, P < 0.01). Approximately one-quarter of athletes reported continuing to play after sustaining a suspected SRC. Chi-square analyses exposed significant differences between male and female athletes failing to report a suspected SRC (χ = 7.69, P < 0.01).
Given the current findings, educational efforts aimed at collegiate athletes may not be enough. Furthermore, it is apparent that sex differences exist in SRC knowledge and reporting behaviors among collegiate athletes.

Excision of the posterosuperior corner of the calcaneus (EPCC) is routinely undertaken in athletes after failure of conservative management of insertional Achilles tendinopathy. Some patients can experience sharp calcaneal pain during postoperative rehabilitation, a sign of a calcaneal bone bruise (CBB).
Case series, level of evidence IV.
University teaching hospital.
This study reports 8 patients who developed postoperative CBB after having started impact training too early.
Patients in whom a diagnosis of CBB had been formulated were followed to return-to-play and resolution of bone edema by MRI.
Detection of CBB after EPCC.
After routine EPCC for insertional Achilles tendinopathy, 8 patients presented with sharp pain for a mean 7.1 weeks (median 6 weeks, range 5-11 weeks) before clinical suspicion of CBB. At that stage, MRI showed clear evidence of a bone bruise, with a diagnosis of CBB formulated at an average of 10.8 postoperative weeks (range 6-16 weeks). https://www.selleckchem.com/products/ly3039478.html Calcaneal bone bruise resolved with modified symptom-free loading. Patients returned to play at average on 5.6 months (range 2-9 months) after the diagnosis of postoperative CBB.
We describe 8 athletes who developed painful CBB following routine EPCC for insertional Achilles tendinopathy after having increased their level of activities too soon after the index procedure. In these patients, the diagnosis of postoperative CBB can be formulated by MRI and more cautious rehabilitation implemented.

Evaluate whether rule changes by the National Federation of State High School Associations (NFHS) were associated with reduced injury rates in US high school ice hockey players.
We compared injury rates for the 3 seasons before the rule changes (2011-2012, 2012-2013, and 2013-2014) with the 2 subsequent seasons (2014-2015 and 2015-2016) using data from the High School Reporting Information Online (RIO) database.

The sports injury surveillance system that supplied the data for this study was funded in part by the Centers for Disease Control and Prevention (grant Nos. R49/CE000674-01, R49/CE001172-01, and R49/CE002106-01) as well as research funding contributions of the NFHS, National Operating Committee on Standards for Athletic Equipment (NOCSAE), DonJoy Orthotics, and EyeBlack. The findings and conclusions in this report are those of the authors and do not necessarily represent the official position of the Centers for Disease Ces achieved their targeted effect.
Among US high school ice hockey athletes, implementation of stricter penalties for boarding and checking from behind was associated with a significant decrease in injury rate due to being checked. Rates of injury due to other mechanisms were not significantly altered, suggesting the rule changes achieved their targeted effect.Traumatic and sport-related sternoclavicular (SCJ) injuries in adolescent athletes are more commonly physeal fractures rather than true SCJ dislocations. Although rare, posterior displacement of the medial clavicular metaphysis after a physeal fracture necessitates prompt evaluation and treatment. Despite the inherent healing ability of physeal separations, delayed or failed diagnosis has the capacity to cause serious complications or fatality secondary to injury of retrosternal structures. Even with the potential severity, a lack of consensus exists in the literature regarding the most appropriate treatment modality. We report an adolescent football player with a medial clavicular physeal fracture with posterior metaphyseal displacement abutting the left brachiocephalic vein. After nonsurgical management and progression to play, the patient returned to play football. This case not only highlights the diagnostic principles of medial clavicular physeal fractures with posterior metaphyseal displacement but also discusses how these challenging injuries can be managed successfully with conservative treatment.
