AbstractObjectives: The objective of this study was to evaluate the feasibility and implementation of a standardized medically supervised concussion protocol established between a city-wide AAA hockey league and a multi-disciplinary concussion program. Methods: We conducted a retrospective review of injury surveillance, clinical and healthcare utilization data from all athletes evaluated and managed through the Winnipeg AAA Hockey concussion protocol during the 2016-2017 season. We also conducted post-season email surveys of head coaches and parents responsible for athletes who competed in the same season. Results: During the 2016-2017 season, 28 athletes were evaluated through the medically supervised concussion protocol, with two athletes undergoing evaluation for repeat injuries (a total of 30 suspected injuries and consultations). In all, 96.7% of the athletes managed through the concussion protocol were captured by the league-designated Concussion Protocol Coordinator and 100% of eligible athletes underwent complete medical follow-up and clearance to return to full hockey activities. Although 90% of responding head coaches and 91% of parents were aware of the concussion protocol, survey results suggest that some athletes who sustained suspected concussions were not managed through the protocol. Head coaches and parents also indicated that athlete education and communication between medical and sport stakeholders were other elements of the concussion protocol that could be improved. Conclusion: Successful implementation of a medically supervised concussion protocol for youth hockey requires clear communication between sport stakeholders and timely access to multi-disciplinary experts in traumatic brain and spine injuries. Standardized concussion protocols for youth sports may benefit from periodic evaluations by sport stakeholders and incorporation of national guideline best practices and resources.

Potential Benefits

The sport literature yields little information concerning the available methods or processes coaches can use to obtain feedback about their coaching. This is unfortunate given that evaluative feedback about one’s coaching performance is useful in terms of providing direction for professional coach development (Mallett & Côté, 2006). As a follow-up to O’Boyle (2014), the purpose of this Best Practices paper is to offer a sample protocol for employing a 360-degree feedback system for coaches working in high performance settings. We draw on a review of the coach evaluation and 360-degree feedback literature, along with insights shared from Canadian intercollegiate head coaches to highlight some of the potential benefits and challenges of implementing a 360-degree feedback system in sport. We then suggest ‘best practices’ for effectively integrating this appraisal system and provide an example coach report to illustrate how feedback would be provided to a coach following a 360-degree feedback protocol. It is our hope that this sample protocol paper will encourage coaches, athletic directors, and other sport administrators to integrate comprehensive coach feedback practices in their sporting programs.

Background: Sports-related cervical spine injuries (CSI) are devastating traumas with the potential for permanent disability. There is a paucity of literature on operative CSI sustained in youth athletes. Hypothesis/Purpose: The aims of this study aims were to review injury characteristics, surgical treatment, and outcomes of severe pediatric CSI encountered in youth sports. Methods: We reviewed children less than 18 years old with operative sports-related CSI at a pediatric Level 1 pediatric trauma center between 2004−2019. All cases underwent modern cervical spine instrumentation and fusion. SCI were stratified according to the American Spinal Injury Association Impairment Scale (ASIA). Clinical, radiographic, and surgical characteristics were compared between groups of patients with and without spinal cord injury (SCI). Results: Three thousand two hundred and thirty-one children (mean, 11.3y±4.6y) were evaluated for CSI at our institution during the 16-year period. The majority of traumas resulted from sports/recreational activities and were seen in 1365 cases (42.3%). Of these, 171/1365 patients (12.5%) were admitted and 29/1365 patients (2.1%) required surgical intervention (mean age, 14.5y±2.88y; range, 6.4y–17.8y). Sports included: eight football (28%), seven wrestling (24%), five gymnastics (17%), four diving (14%), two trampoline (7%), one hockey (3%), one snowboarding (3%), and one biking injury (3%). Mechanisms were 19 hyperflexion (65%), eight axial loading (28%), and two hyperextension injuries (7%). The majority of operative CSI were fractures (79%) and/or subaxial defects (72%). Seven patients (30%) sustained SCI and three patients (10%) spinal cord contusion or myelomalacia without neurologic deficits. The risk of SCI increased with age (15.8y vs. 14.4y; p=0.03) and axial loading mechanism (71% vs. 14%; p=0.003). Postoperatively, two SCI patients (29%) improved 1 ASIA Grade and one (14%) improved 2 ASIA Grades. Increased complications developed in SCI than patients without SCI (mean, 2.0 vs 0.1 complications; p=0.02). Clinical and radiographic fusion occurred in 24/26 patients (92%) with adequate follow-up (median, 32 months). Ten patients returned to their previous activity and nine to sports with a lower level of activity. Conclusion: The overall incidence of sports-related operative CSI is low. Age- and gender discrepancies exist, with male adolescent athletes most commonly requiring surgery. Hyperflexion injuries had a good prognosis; however, older males with axial loading CSI sustained in contact sports were at greatest risk of SCI, complications, and permanent disability.

Abstract Large-scale deployment of safe and durably effective vaccines can curtail the COVID-19 pandemic.1−3 However, the high vaccine efficacy (VE) reported by ongoing phase 3 placebo-controlled clinical trials is based on a median follow-up time of only about two months4−5 and thus does not pertain to long-term efficacy. To evaluate the duration of pro- tection while allowing trial participants timely access to efficacious vaccine, investigators can sequentially cross participants over from the placebo arm to the vaccine arm according to priority groups. Here, we show how to estimate potentially time-varying placebo-controlled VE in this type of staggered vaccination of participants. In addition, we compare the per- formance of blinded and unblinded crossover designs in estimating long-term VE.

Tempeh is a traditional Indonesian food that has many advantages as food and the process of making it is quite simple. However, the community knowledge about tempeh and the skills to produce healthy tempeh are still low. This community service aimed to increase the knowledge about tempeh and to improve the skills of its manufacturers in making healthy and good quality tempeh. The activities were carried out for mothers living in Villa Dago Tol complex, Ciputat, South Tangerang 15414, by using the methods of counseling, demonstration, and mentoring. Monitoring was conducted to measure the success rate of participants in producing healthy tempeh. The level of community knowledge about tempeh was evaluated through survey method. The results of counseling, demonstration, and mentoring succeeded in improving the participant skills as seen from the participants' success in following the healthy tempeh-making procedure. The results were also reinforced by the results of monitoring where all participants managed to create healthy tempeh. Survey results showed participants’ increasing knowledge of healthy tempeh and motivation in producing healthy tempeh. Assessment of participants showed good results, especially in improving knowledge (73% stated strongly agree and the rest agree). The ability of the facilitators in delivering the material was also considered good by the participants (92% stated strongly agree and the rest agree). As a follow-up, the participants suggested that the training be extended to the other communities and the training also include a variety of topics such as the manufacturing of tofu, healthy food processing, sewing, and many others.

Thirty-four patients aged from 3 to 17 years were operated on for noncomplicated unstable injuries of the spine. The operation was performed within the next few hours or days after trauma in 15 cases and significantly later (in 2 to 6 months) in 19 cases. In the first group the surgery included indirect posterior instrumental reduction and stabilization of the spine. In the second group a two-stage surgery was performed simultaneously. The first stage included anterior decompression and stabilization, and the second – posterior instrumentation. In both groups the posterior fusion with bone autograft was done. The post-op follow-up was 5 years. The correction of deformity, spinal stabilization and pain arrest were achieved in all cases. The surgical treatment of unstable noncomplicated spinal injuries in children must be conducted by emergency indications within the first hours and days after trauma.

Information Seeking Behaviors

Mathematicians in academic institutions utilize a variety of resources and strategies to seek, find, and use scholarly information and news. Using a sample of mathematicians, researchers surveyed 112 students and faculty at four Canadian university institutions to explore self-perceived success rates, resources consulted, databases used, use of social media, and citation management systems. Further, 12 follow-up interviews were completed with mathematicians to better interpret survey results, resulting information-seeking behaviors, choices, strategies, and feelings on keeping up to date with information needs. According to survey results, a minority of mathematicians (12.5 percent) acknowledged that they were successfully keeping up to date. However, a significant number of mathematicians (28.6 percent) indicated that they were unsuccessful and could do better in remaining current with information needs. Co-investigators, using qualitative analyses, identified four emergent themes related to remaining current: (1) The “slower pace of math” pervades all aspects of this discipline;” (2) There are “too many papers – and not enough time” to effectively search, evaluate, and read scholarly papers of interest; (3) Mathematicians collectively acknowledge that they are open to strategies and technologies where they “could do better” keeping up to date; and (4) Mathematicians have divided loyalties using databases when searching for information by means of “MathSciNet in a Google world.” Additional insights document how mathematicians are guided by mathematical peculiarities and discipline-specific practices. This study helps to shed light on opportunities for academic librarians to identify and meet mathematicians’ evolving information needs.

Introduction. More than a quarter of total number of posterior fixations of thoracolumbar spine is unsuccessful. Material and methods. The aim is to compare short and long fixation of thoracolumbar spine injuries. During the period of 2006 to 2015 we examined 99 patients at the Department of Orthopedic Surgery and Traumatology of Clinical Center of Vojvodina. Short fixation was performed in 63 cases and long fixation in 36 cases. All patients underwent clinical, radiographic and neurological evaluation. Mean age in the short fixation group was 47 (18-66) and in the long fixation group it was 43 (17-70). Mean follow-up time was 4,5 years. Results. Implants were extracted in 14 cases of short and in 4 cases of long fixation. Collapse of anterior part of vertebral body developed in 28,45% in the short fixation group and in 22,43% in the long fixation group whereas angulation value was 10,2o and 12,3o respectively. Mean low back outcome scale value was 61 points in the short fixation group and 50 in the long fixation group. There were 22 patients with neurological deficit. Full recovery was recorded in 8 patients (36,4%) of the short fixation group and in 17 patients (22,7%) of the long fixation group. Complications developed in 15 patients (23,8%) of the short fixation group and 11 (30,6%) of the long fixation group. Conclusion. Short fixation is biomechanically weaker but provides a better functional recovery than long fixation.

SummaryWe are entering a new era in the study of variable and transient radio sources. This workshop discussed the instruments and the strategies employed to study those sources, how they are identified and classified, how results from different surveys can be compared, and how radio observations tie in with those at other wavelengths. The emphasis was on learning what common ground there is between the plethora of on-going projects, how methods and code can be shared, and how best practices regarding survey strategy could be adopted.The workshop featured the four topics below. Each topic commenced with a fairly brief introductory talk, which then developed into discussion. By way of preparation, participants had been invited to upload and discuss one slide per topic to a wiki ahead of the workshop.1. Telescopes, instrumentation and survey strategy. New radio facilities and on-going projects (including upgrades) are both studying the variability of the radio sky, and searching for transients. The discussion first centred on the status of those facilities, and on projects with a time-domain focus, both ongoing and planned, before turning to factors driving choices of instrumentation, such as phased array versus single pixel feeds, the field of view, spatial and time resolution, frequency and bandwidth, depth, area, and cadence of the surveys.2. Detection, pipelines, and classification. The workshop debated (a) the factors that influence decisions to study variability in the (u,v) plane, in images, or in catalogues, (b) whether, and how much, pipeline code could potentially be shared between one project and another, and which software packages are best for different approaches, (c) how data are stored and later accessed, and (d) how transients and variables are defined and classified.3. Statistics, interpretation, and synthesis. It then discussed how (i) the choice of facility and strategy and (ii) detection and classification schemes influence what is seen (in terms of types of object and rates) by different surveys, (iii) how results from different surveys could be compared, and (iv) how what we know from existing surveys drives choices (i) and (ii), particularly as regards finding new classes of object.4. Multiwavelength approaches. The workshop concluded by discussing what information is needed from wavelengths other than radio in order to classify transients and variables adequately and predict their rates as a function of topics (1), (2) and (3). It asked what the constraints are on responding to, and issuing triggers for, follow-up observations, and how that might feed back into considerations for designing our telescopes and surveys.

This study assessed the vision-screening practices of all preschools and elementary schools during the spring of 2000 in the Heartland Area Education Agency (AEA) in central Iowa. Surveys were returned by 7% of the preschools and 56% of the elementary schools. Survey questions were drafted based on recommendations from the Iowa Vision Screening Program Guidelines, which were distributed to all Iowa school districts in 1997. Areas surveyed included vision-screening personnel, attainment of students’ visual history, rescreening practices, referral and follow-up, and screening procedures. Survey results indicated that there is a need for improvement to standardize vision-screening procedures within Heartland AEA. Time and effort are invested in activities that are not recommended, and not enough effort is being put into recommended activities such as obtaining vision histories, rescreening to avoid overreferrals, and follow-up to make sure students receive required treatment.
