Investigation of the Concussion Goggle™ Education Program with Secondary School Athletic Teams: A Pilot Study

Background: Researchers have investigated different types of concussion education programs within various populations with mixed results. To date, no research has been published using the Concussion Goggles™ educational program Objective: To compare secondary school student-athletes’ knowledge about concussions before and after attending a concussion education program using the Concussion Goggles™. Design: Pre- posttest. Setting: Public secondary school. Patients or Other Participants: 41 secondary school students (14 girls soccer players, 14 boys basketball players, and 13 girls basketball players) with a mean age of 15.37 ± 1.22 years. Intervention(s): Participants completed the Concussion Goggles™ concussion educational program consisting of PowerPoint slides with 3 activities and short video segments within the presentation. Participants completed a test developed by the manufacturers of the Concussion Goggles™ educational program prior to and following the intervention to measure change in concussion knowledge. Main Outcome Measure(s): A 3-way mixed factorial analysis of variance (sport x grade level x gender) for repeated measures was utilized to determine statistical significance. Results: A statistically significant difference between the overall pretest (9.37 ± 1.20) and posttest (9.63 ± 1.04) scores was not found (p = 0.28). Repeated measures analysis did not indicate significant interaction effects for test score x grade (p = 0.18), test score x sport (p = 0.63), nor test score x grade x sport (p = 0.96). Conclusion: The Concussion Goggle™ education program did not affect participant knowledge of concussions in the posttest. In its current form, the Concussion Goggle™ program may not be an effective concussion education program.

Self-Directed Learning Readiness And Self-Determination For Selected Rehabilitation Professional Students: The Impact Of Clinical Education

In a time of rapidly changing medical information, practitioners must have learning skills that enable them to be effective life-long learners. A part of an examination of a final clinical internship for rehabilitation professionals was a pre-post measure of learner self-direction and self-determination. Two instruments, the Self-Directed Learning Readiness Scale (SDLRS) and the Academic Motivation Scale (AMS- reported as Self-Determination Index (SDI) were used with a sample of Doctorate of Physical Therapy (DPT) and Master of Occupational Therapy (MOT) students. Pre-testing occurred just prior to and post-testing just after the subjects’ final clinical assignments. Both groups increased mean scores from pre- to post-test for the SDLRS (p = .01, mean increase 7.29) and the SDI (p = .01, mean increase 0.91). Results of this study support the use of the SDLRS and AMS as means to evaluate self-directed learning readiness and self-determination in rehabilitation professional students

Room temperature exsolution of CdS nanodots on A-site deficient cotton-ball like titanate perovskite nanoparticles for H2 production under visible light

Funding: The authors thank EPSRC for funding for a Critical Mass Project EP/R023522/1 and electron microscopy facilities EP/R023751/1 and EP/L017008/1.Exsolution of nanoparticles followed by chemical treatment (“chemistry at a point”) is a very exciting approach to the smart design of functional materials such as visible light active photocatalysts. Unfortunately, the usually utilized thermal reduction approach is not feasible for low melting point metals and compounds such as Cd and CdO. Here a hydrothermal approach to prepare exsolved CdS nanodots on cotton ball-like perovskite supports is described. The titanate-based photocatalyst is synthesized using a hydrothermal process followed by room-temperature sulfidation. The hydrothermal route directs A-site doping of Cd2+ via hydroxyl group incorporation in the titanate lattice. Formation of CdS via exsolution provides a high H2 production mass activity of 3050 µmol g−1 h−1 under visible light with only 5 mol.% Cd doping of the titanate. Moreover, the strong CdS-support interaction offers good cycling stability under UV–vis and visible light irradiation. This is the first report describing the exsolution of CdS nanodots at room temperature and shows its advantages for photocatalytic activity.Publisher PDFPeer reviewe

Optical Spectra of SNR Candidates in NGC 300

We present moderate-resolution (<5A) long-slit optical spectra of 51 nebular objects in the nearby Sculptor Group galaxy NGC 300 obtained with the 2.3 meter Advanced Technology Telescope at Siding Spring Observatory, Australia. Adopting the criterion of [SII]/Ha>=0.4 to confirm supernova remnants (SNRs) from optical spectra, we find that of 28 objects previously proposed as SNRs from optical observations, 22 meet this criterion with six showing [SII]/Ha of less than 0.4. Of 27 objects suggested as SNRs from radio data, four are associated with the 28 previously proposed SNRs. Of these four, three (included in the 22 above) meet the criterion. In all, 22 of the 51 nebular objects meet the [SII]/Ha criterion as SNRs while the nature of the remaining 29 objects remains undetermined by these observations.Comment: Accepted for publication in Astrophysics & Space Scienc

A retrospective look at the predictions and recommendations from the 2009 AMIA Policy Meeting: Did we see EHR-related clinician burnout coming?

Clinicians often attribute much of their burnout experience to use of the electronic health record, the adoption of which was greatly accelerated by the Health Information Technology for Economic and Clinical Health Act of 2009. That same year, AMIA\u27s Policy Meeting focused on possible unintended consequences associated with rapid implementation of electronic health records, generating 17 potential consequences and 15 recommendations to address them. At the 2020 annual meeting of the American College of Medical Informatics (ACMI), ACMI fellows participated in a modified Delphi process to assess the accuracy of the 2009 predictions and the response to the recommendations. Among the findings, the fellows concluded that the degree of clinician burnout and its contributing factors, such as increased documentation requirements, were significantly underestimated. Conversely, problems related to identify theft and fraud were overestimated. Only 3 of the 15 recommendations were adjudged more than half-addressed

Functional diversity of marine ecosystems after the Late Permian mass extinction event

Article can be accessed from http://www.nature.com/ngeo/journal/v7/n3/full/ngeo2079.htmlThe Late Permian mass extinction event was the most severe such crisis of the past 500 million years and occurred during an episode of global warming. It is assumed to have had significant ecological impact, but its effects on marine ecosystem functioning are unknown and the patterns of marine recovery are debated. We analysed the fossil occurrences of all known Permian-Triassic benthic marine genera and assigned each to a functional group based on their inferred life habit. We show that despite the selective extinction of 62-74% of marine genera there was no significant loss of functional diversity at the global scale, and only one novel mode of life originated in the extinction aftermath. Early Triassic marine ecosystems were not as ecologically depauperate as widely assumed, which explains the absence of a Cambrian-style Triassic radiation in higher taxa. Functional diversity was, however, significantly reduced in particular regions and habitats, such as tropical reefs, and at these scales recovery varied spatially and temporally, probably driven by migration of surviving groups. Marine ecosystems did not return to their pre-extinction state, however, and radiation of previously subordinate groups such as motile, epifaunal grazers led to greater functional evenness by the Middle Triassic

A risk prediction model for the assessment and triage of women with hypertensive disorders of pregnancy in low-resourced settings: the miniPIERS (Pre-eclampsia Integrated Estimate of RiSk) multi-country prospective cohort study.

BACKGROUND: Pre-eclampsia/eclampsia are leading causes of maternal mortality and morbidity, particularly in low- and middle- income countries (LMICs). We developed the miniPIERS risk prediction model to provide a simple, evidence-based tool to identify pregnant women in LMICs at increased risk of death or major hypertensive-related complications. METHODS AND FINDINGS: From 1 July 2008 to 31 March 2012, in five LMICs, data were collected prospectively on 2,081 women with any hypertensive disorder of pregnancy admitted to a participating centre. Candidate predictors collected within 24 hours of admission were entered into a step-wise backward elimination logistic regression model to predict a composite adverse maternal outcome within 48 hours of admission. Model internal validation was accomplished by bootstrapping and external validation was completed using data from 1,300 women in the Pre-eclampsia Integrated Estimate of RiSk (fullPIERS) dataset. Predictive performance was assessed for calibration, discrimination, and stratification capacity. The final miniPIERS model included: parity (nulliparous versus multiparous); gestational age on admission; headache/visual disturbances; chest pain/dyspnoea; vaginal bleeding with abdominal pain; systolic blood pressure; and dipstick proteinuria. The miniPIERS model was well-calibrated and had an area under the receiver operating characteristic curve (AUC ROC) of 0.768 (95% CI 0.735-0.801) with an average optimism of 0.037. External validation AUC ROC was 0.713 (95% CI 0.658-0.768). A predicted probability ≥25% to define a positive test classified women with 85.5% accuracy. Limitations of this study include the composite outcome and the broad inclusion criteria of any hypertensive disorder of pregnancy. This broad approach was used to optimize model generalizability. CONCLUSIONS: The miniPIERS model shows reasonable ability to identify women at increased risk of adverse maternal outcomes associated with the hypertensive disorders of pregnancy. It could be used in LMICs to identify women who would benefit most from interventions such as magnesium sulphate, antihypertensives, or transportation to a higher level of care
