Published: July 2024

OBJECTIVE

Concussions are self-limited forms of mild traumatic brain injury (TBI). Gradual return to play (RTP) is crucial to minimizing the risk of second impact syndrome. Online patient educational materials (OPEM) are often used to guide decision-making. Previous literature has reported that grade-level readability of OPEM is higher than recommended by the American Medical Association and the National Institutes of Health. The authors evaluated the readability of OPEM on concussion and RTP.

METHODS

An online search engine was used to identify websites providing OPEM on concussion and RTP. Text specific to concussion and RTP was extracted from each website and readability was assessed using the following six standardized indices: Flesch Reading Ease (FRE), Flesch-Kincaid Grade Level, Gunning Fog Index, Coleman-Liau Index, Simple Measure of Gobbledygook Index, and Automated Readability Index. One-way ANOVA and Tukey’s post hoc test were used to compare readability across sources of information.

RESULTS

There were 59 concussion and RTP articles, and readability levels exceeded the recommended 6th grade level, irrespective of the source of information. Academic institutions published OPEM at simpler readability levels (higher FRE scores). Private organizations published OPEM at more complex (higher) grade-level readability levels in comparison with academic and nonprofit institutions (p < 0.05).

CONCLUSIONS

The readability of OPEM on RTP after concussions exceeds the literacy of the average American. There is a critical need to modify the concussion and RTP OPEM to improve comprehension by a broad audience.

Published: July 2024

OBJECTIVE

Continued play following concussion can lead to worse outcomes and longer recoveries compared with athletes who immediately report. This has been well documented in youth athletes, while less attention has been paid to collegiate athletes despite differences in healthcare access, recovery trajectories, and additional pressures to play. Therefore, the purpose of this study was to determine if continuing to play immediately following a concussion influenced clinical outcomes and recovery time in collegiate athletes.

METHODS

A prospective, repeated-measures design was used to compare clinical outcomes and recovery time between collegiate athletes who continued playing (n = 37) and those immediately removed (n = 56) after a concussion. Assessments were conducted within 5 days of the concussion and at full medical clearance (FMC; ± 3 days) using the Sport Concussion Assessment Tool-5th edition (SCAT5), Vestibular/Ocular Motor Screening assessment, and High-Level Mobility Assessment Tool. Mann-Whitney U-tests determined differences in clinical outcomes between groups. Cox proportional hazards regression models examined the relationship between factors associated with days to symptom resolution and days to FMC, and covariates were selected a priori based on previous literature. Hazard ratios with 95% CIs were reported for each predictor variable.

RESULTS

Significant differences were found in SCAT5 concentration composite scores (p = 0.010) and SCAT5 delayed recall composite scores (p = 0.045) at the acute visit and near point of convergence average distance (cm; p = 0.005) at the FMC visit between the group who continued to play and those who were immediately removed. There were no differences between groups in days to symptom resolution (10 vs 7 days, p = 0.05) and days to clearance (13 vs 11.50 days, p = 0.13). The association between groups and days to symptom resolution (χ2[4] = 5.052, p = 0.282), and days to clearance (χ2[4] = 3.624, p = 0.459) were not significant when adjusting for covariates.

CONCLUSIONS

Collegiate athletes who continued to play following concussion did not exhibit worse clinical outcomes or recovery times compared with athletes who were immediately removed. While the lack of differences found in this study could be supported by prior literature, including improved education, awareness, reporting attitudes, and concussion management at the collegiate level in recent years, the authors believe discrepancies are more likely due to study-specific differences (e.g., sample size, care setting, and timing). Therefore, these findings should not diminish the dangers of continued play and the importance of timely removal after concussion.

Published: July 2024

OBJECTIVE

Epidemiology provides fundamental opportunities to protect student-athlete health. The goal of this study was to describe the epidemiology of sport-related concussion (SRC) across 8 years (2015/2016–2022/2023) and compare boys’ and girls’ sports for SRC incidence and SRC mechanisms.

METHODS

This was a retrospective cohort study performed using a statewide high school head injury surveillance system of high school student-athletes (n = 2,182,128; boys, n = 1,267,389; girls, n = 914,739). Exposures of interest included study year and boys and girls in comparable sports. Clinical incidence was calculated by dividing SRC counts in each sport by the number of participants per 100 player-seasons and presented with 95% CIs. The 2019/2020 and 2020/2021 data were included in the analysis, however caution is warranted due to the COVID-19 pandemic. Clinical incidence ratios (CIRs) were estimated for sex-comparable sports, and significance was determined if 95% CIs excluded 1.00. The authors compared mechanism of injury in boys’ and girls’ comparable sports with chi-square analyses (p < 0.05).

RESULTS

Among 25,482 total SRCs, the overall clinical incidence of SRC for all boys and girls was 1.17 (95% CI 1.15–1.18) per 100 player-seasons across all years. Across all years, the overall clinical incidence in boys’ sports was 1.34 (95% CI 1.32–1.36) per 100 player-seasons, and 0.93 (95% CI 0.91–0.95) per 100 player-seasons in girls’ sports. Boys’ sports with the highest clinical incidence included football, ice hockey, and wrestling. Girls’ sports with the highest clinical incidence included basketball, soccer, lacrosse, competitive cheer, and gymnastics. Girls consistently had higher SRC rates relative to boys for baseball/softball, basketball, and soccer (CIR range 1.65 [95% CI 1.41–1.93] to 3.32 [95% CI 2.67–4.16]). Girls had lower SRC in lacrosse in 2015/2016 (CIR 0.63, 95% CI 0.40–0.97); no difference in 2016/2017–2020/2021, but had higher clinical incidence in 2021/2022 (CIR 1.69, 95% CI 1.18–2.44) relative to boys. In boys the most common mechanism of SRC occurred from person-to-person contact (n = 8752, 62.8%), whereas girls commonly sustained SRC from person-to-object contact (n = 2369, 33.4%) and from person-to-person contact (n = 2368, 33.4%). There were significant associations between boys’ versus girls’ sports and mechanism of injury within baseball/softball (χ2 = 12.71, p = 0.005); basketball (χ2 = 36.47, p < 0.001); lacrosse (χ2 = 185.15, p < 0.001); and soccer (χ2 = 122.70, p < 0.001).

CONCLUSIONS

These findings can help understand the potential impact of interventions aimed at preventing or reducing SRC. Including girls’ sports within this study extends research for a largely underrepresented group.

Published: July 2024

Kroniki parafialne oraz przekazy o podobnym charakterze stanowią nierzadko jedno z najważniejszych źródeł do historii określonej parafii, miejscowości i lokalnej społeczności. Kronika parafii Choceń autorstwa ks. Władysława Siemaszki została spisana w latach 1914-1918 i obejmuje okres od XII wieku do 1913 roku. Podzielona jest na dwie części. Pierwsza (30% całości kroniki), składająca się z czterech rozdziałów, poświęcona jest dziejom parafii Choceń od XII wieku do 1896 roku. Została w niej zarysowana historia wsi i parafii Choceń, ze szczególnym uwzględnieniem uposażenia parafii oraz krótką charakterystyką jej rządców. Druga część (70% całości kroniki), zawierająca dziewięć rozdziałów, opowiada o nowych dziejach parafii choceńskiej, czyli od momentu przybycia do niej w styczniu 1897 roku ks. W. Siemaszki. Autor kolejno przedstawia stan materialny i sytuację społeczno-gospodarczą w parafii, którą zastał po przyjeździe do Chocenia (kościół, budynki parafialne, grunty parafialne, wsie należące do parafii, dwory, strukturę własnościową, liczbę ludności). Dużo zapisów dotyczy budowy nowej plebanii, nowych budynków gospodarczych i nowego kościoła oraz wysiłków podejmowanych w związku z tymi przedsięwzięciami. Kronikę kończy opis wizyty i konsekracji kościoła dokonanej przez bp. Stanisława Zdzitowieckiego we wrześniu 1913 roku. Edycja kroniki parafii choceńskiej (diecezja włocławska) ks. Siemaszki jest realizacją postulatu zgłaszanego przez historyków, a dotyczącego edycji źródeł do dziejów Kościoła w Polsce, w tym zwłaszcza kronik parafialnych.

Authors: Bangrowska Agnieszka , Maciąg Tadeusz
Published: July 2024

Przedmiotem badań podjętych w artykule była analiza mikrobiologiczna wszystkich XVII-wiecznych druków kazań pogrzebowych (84 woluminy) ze zbiorów Biblioteki Fundacji Wiktora hr. Baworowskiego we Lwowie. Analizę stopnia zagrożenia mikrobiologicznego wykonano na drukach, które charakteryzowały się wyraźnym działaniem mikroorganizmów, tj. wszelkie zabrudzenia, liczne zaplamienia, przebarwienia czy deformacje papieru. Z wszystkich kolekcji pobrano próbki na obecność grzybów pleśniowych. Zastosowano metodę odcisku, wykorzystując sterylny wilgotny krążek bibuły o średnicy 5 cm, który był odciskany w miejscach charakteryzujących działalność mikroorganizmów. Pobraną próbkę przenoszono na szalkę Petriego z pożywką według receptury Czapek-Doxa. Tak przygotowane próbki inkubowano w cieplarce w temperaturze 28°C. Za optymalny przedział czasowy, po którym grzybnia zarośnie całą szalkę przyjęto 21 dni. Przeprowadzone badania oceny stopnia zagrożenia mikrobiologicznego wykazały, że w dwóch przypadkach średnica wzrostu grzybni wyniosła 3 cm po siedmiu dniach inkubacji, co stanowi 22% wszystkich badanych woluminów. Wywnioskowano zatem, że w badanym materiale jest obecność żywej grzybni, a co za tym idzie – dany obiekt klasyfikuje się do natychmiastowej interwencji konserwatorskiej. Pozostałe obiekty nie wymagają ingerencji. Ocena zagrożeń mikrobiologicznych została uzupełniona o jakościową analizę mikroorganizmów.
THERMOKINETIC DIMENSIONS OF RARE EARTH COMPLEXES OF ANTIPYRALDEHYDE SCHIFF BASES
Authors: Nambiar M.K. Geetha , G. Rijulal  , Krishnakumar A. , Krishnan K. Anoop
Published: July 2024

Thermogravimetric investigations of rare earth complexes [Ln(3MPMAFA)2(NO3)3] and [Ln(4MPMAFA)2(NO3)3] have been performed. All the complexes have two decomposition stages, with the formation of the respective lanthanide oxide, Ln2O3, as the final residue. Using the Coats-Redfern approach, the kinetic aspects for each decomposition stage were assessed from the TG data. The lowering of the steric strain of intermediate molecules is due to the higher entropy of activation of the second phase decomposition than the first stage. The entropy of activation has positive values, which means that the decomposition products have lower-ordered structures than the initial constituents, which causes the reactions to proceed more quickly than normal. Using the many mechanistic equations proposed by Satava, the mechanisms for the decomposition reactions were computed.

Published: July 2024

Mathematical problem-solving ability is one of the skills that need to be taught to students since learning in elementary school. Mathematical problem-solving ability can be known from students' understanding of the information known and asked in the problem. They are also expected to be able to plan problem-solving strategies and perform appropriate calculation operations. Fifth-grade students of public elementary schools in Kupang City, East Nusa Tenggara still have difficulty solving problem solving problems. For this reason, the Schema Based Instruction (SBI) method was applied to improve students' mathematics problem-solving skills. This study aims to determine the effect of the SBI method on the mathematical problem-solving ability of fifth-grade elementary school students. This research used an experimental method with research design is posttest-only control group design. The research was conducted in class V in one of the public schools in Kelapa Lima District, Kupang City, NTT. The research instrument was a post-test question in the form of an essay of six numbers. The post-test results were tested using the T-test and post-hock to determine whether there was an effect of the SBI method on mathematical problem-solving skills. The calculation results show that the learning outcomes of students who learn using the SBI method are higher than students who learn using the expository method. It can be concluded that the SBI method can be used as one of the references for learning methods that can be used in learning mathematics in elementary schools to improve mathematical problem-solving skills.

Authors: Mega AM. Mega Purnamatati , Meiliasasi
Published: July 2024

Geometric concepts in mathematics possess abstract properties that require a spatial reasoning process. Evaluating problem-solving abilities through HOTS (Higher-Order Thinking Skills) questions focusing on spatial reasoning is crucial for enhancing students' skills. The aims of this research are: (1) To understand the process of students' problem-solving skills in geometry HOTS based on spatial reasoning; (2) To analyze and pinpoint the challenges faced by students in solving geometry problems through HOTS questions that involve spatial reasoning. This study employs a qualitative approach with data analysis following the Miles and Huberman model, comprising data collection, data reduction, data presentation, and conclusion. The data gathered includes test outcomes, interviews, and documentation. The participants consist of 2 fifth-grade teachers and 3 students from SD N Lulut 05 and SD N Lulut 03. The findings indicate the necessity of regular training for students to effectively tackle HOTS questions and avoid difficulties. The test results showed that the spatial reasoning of the two schools reached 32% in the high category, while the HOTS geometry problem solving reached 30% in the high category. Students with strong spatial reasoning skills excel in solving HOTS problems, whereas those with moderate to low abilities encounter challenges in geometry problem-solving. Therefore, the spatial reasoning skills of students with different proficiency levels vary in addressing geometric problems compared to those with high mathematical abilities. A tailored learning strategy is essential to cater to the diverse needs of these students.
