Authors: Байярсайхан Бадарч , Саая Оюмаа Маадыр-ооловна 
Published: December 2022

В статье рассматривается языковая ситуация среди цэнгэльских тувинцев — этнических тувинцев, проживающих в сумоне Цэнгэл Баян-Улэгэйского аймака Северо-Западной Монголии, разговаривающих на цэнгэльский говор алтайского диалекта тувинского языка. Анализ опирается на результаты социолингвистического опроса 2018 г., которым были охвачены 180 респондентов — жителей с. Цэнгэл. Охарактеризован статус, сферы функционирования тувинского языка, определены уровни языковой компетенции тувинцев сумона Цэнгэл, влияние образования на уровень владения родным языком.
Опрос показал, что большинство респондентов в повседневной жизни предпочитают разговаривать на родном языке, при этом в своей речи допускают употребление монгольских заимствований, что осознается ими в полной мере. Выявлены некоторые экстралингвистические явления, повлиявшие на особенности языковой ситуации: влияние политической ситуации на антропонимию, родовая самоидентификация респондентов; уровень их мотивации на сохранение и передачу родного языка следующим поколениям и др.
Цэнгэльские тувинцы Монголии в большинстве являются полилингвами, владеющими кроме родного и монгольского языков, также и казахским. Отмечается усиление роли монгольского языка, как языка межнационального общения. Мотивированность большинства цэнгэльских тувинцев на сохранение и передачу родного языка, как фактора их самоидентификации, наряду с государственной поддержкой монгольского правительства языка и культуры тувинцев, способствует развитию тувинского языка в сумоне Цэнгэл.

Published: December 2022

Objectives:
The diagnosis of lymphoma on cytologic preparations and core needle biopsies (CNBs) is often challenging due to limited material that precludes additional ancillary testing for accurate classification. We describe our institutional experience with patients who ultimately received a diagnosis of lymphoma using cytologic preparations and CNB material along with additional ancillary testing.

Material and Methods:
All patients whose cytology material (fluids, cytologic smears, and cell block) and CNB resulted in a diagnosis of lymphoma, atypical lymphoid population, or suspicious for lymphoma were retrieved. Diagnoses of lymphoma followed the established nomenclatures of the World Health Organization (WHO). For all cases, the ancillary test profiles were captured and summarized.

Results:
Of 389 cases identified, 17 (4.4%) were diagnosed as atypical lymphoid cells and 31 (7.9%) were suspicious for lymphoma resulting in an indeterminate rate of 12.3%. The rest of the malignant cases (341; 87.7%) were classified using 2017 WHO lymphoid classification system. Six low-grade and 26 high-grade B-cell lymphomas were not further classified because of limited tissue. B-cell lymphomas were the largest category (73.0%): Primarily diffuse large B-cell lymphoma (21.4%), followed by follicular lymphoma (17.5%) and chronic lymphocytic leukemia/small lymphocytic lymphoma (10.9%). A total of 140 cases (36.0%) had flow cytometry results, but 30 specimens (21.4%) were insufficient. Cytogenetic and molecular studies were performed for 78 cases (20.0%).

Conclusion:
Full classification of lymphomas is possible with combined cytologic preparations and CNB material and it is an attractive first sampling modality in the diagnostic process for this disease group.
An Updated Model Does Not Reveal Sex Differences in Patellofemoral Joint Stress during Running
Authors: Jacobson Laura , Vannatta C. Nathan , Schuman Catherine , Kernozek Thomas W. 
Published: December 2022

Background Structure-specific loading may have implications in understanding the mechanisms of running related injury. As females demonstrate a prevalence of patellofemoral pain twice that of males, this may indicate differences in patellofemoral loads between males and females. Previous works investigating differences in patellofemoral joint stress have shown conflicting results, but the models employed have not used estimates of muscle forces or sex specific contact areas. Hypothesis/Purpose The aim of this study was to examine sex differences in patellofemoral joint stress using an updated model to include estimates of quadriceps muscle force and sex-specific patellofemoral contact area. Study Design Descriptive Laboratory Study Methods Forty-five healthy recreational runners ran at a controlled speed down a 20-meter runway. Kinetic and kinematic data were utilized to estimate muscle forces using static optimization. Quadriceps muscle force was utilized with sex-specific patellofemoral joint contact area in a two-dimensional patellofemoral joint model to estimate patellofemoral joint stress. Multivariate tests were utilized to detect sex differences in patellofemoral loading and hip and knee kinematics. Results No differences were found between sexes in measures of patellofemoral loading or quadriceps force. Females displayed a reduced knee extension moment and greater hip adduction and internal rotation than males. Conclusion The inclusion of static optimization to estimate quadriceps muscle force and sex-specific contact area of the patellofemoral joint did not reveal sex differences in patellofemoral joint stress, but differences in non-sagittal plane hip motion were detected. Therefore, two-dimensional patellofemoral models may not fully characterize differences in patellofemoral joint stress between males and females. Three-dimensional patellofemoral models may be necessary to determine if sex differences in patellofemoral joint stress exist. Level of Evidence 3b

Published: December 2022

Background It is presently unclear how the cessation of high school sport has affected injury incidence at different socioeconomic levels. The COVID-19 pandemic may have disproportionately affected athletes of lower socioeconomic status, potentially increasing injury risk in this population. Purpose To 1) Describe athlete injury incidence prior to and during the 2019-2020 and 2020-2021 school years in high school athletes by socioeconomic status; 2) Investigate the association between socioeconomic status and injury incidence in high school athletes. Study Design Ecological Study Methods High schools were matched between the 2019-2020 and 2020-2021 school years. All athletes from all sports were included. High school socioeconomic status was determined by the school district median household income. Socioeconomic strata were defined as <$30,000, $30,000-50,000, $50,001-100,000, and >$100,000. Injury incidence proportion with 95% confidence interval (95% CI) was calculated for each academic year. Mixed effects negative binomial models with robust errors were performed to assess the association between the incidence proportion ratio and high school median household income. Six states and 176 high schools were included (2019-2020: 98,487 athletes; 2020-2021: 72,521 athletes). Results Injury incidence increased in three of four socioeconomic strata during the 2020-2021 year (<$30,000: 2019-2020: 15.6 (13.1-18.1), 2020-2021: 26.3 (23.1-29.6); $30,000-50,000: 2019-2020: 7.8 (7.1-8.6), 2020-2021: 14.9 (13.8-15.9); $50,001-100,000: 2019-2020: 15.1 (14.7-15.4), 2020-2021: 21.3 (20.9-21.8); >$100,000: 2019-2020: 18.4 (18.1-18.8), 2020-2021: 17.3 (16.8-17.7)). An association was observed between injury incidence ratio and log median high school household income in 2019-2020 [1.6 (1.1-2.5)] but not 2020-2021 [1.1 (0.8-1.6)] school years. Conclusions Athletes from lower socioeconomic high schools reported increased injury incidence compared to higher socioeconomic high schools during the 2020-2021 academic school year. These results highlight the increased COVID-19 pandemic vulnerability in athletes from lower socioeconomic high schools. High school sport stakeholders should consider how abrupt sport stoppage can affect lower socioeconomic athletes. Level of Evidence 2

Authors: Sugimoto Dai , Del Bel Michael , Butler Lauren 
Published: December 2022

Background Barriers and facilitators to research in sports medicine (SM) by physicians and allied health (AH) professions such as physical therapists and athletic trainers are understudied. The purpose of this research was to examine and compare research barriers, facilitators, and other research related facets including interests, comfort, knowledge, and resources among SM physicians and AH practitioners. Study Design Cross-sectional survey Methods The survey was sent to Pediatric Research in Sports Medicine (PRiSM) members. The survey was designed to ask respondents to identify their top barrier and facilitator to conducting research. Research interest (binary), self-rated comfort reading research articles (0-100 scale), self-rated knowledge conducting research independently (0-100 scale), and available research resources were evaluated. Descriptive statistics, chi-square, and t-tests were used to compare the responses between SM physicians and AH practitioners. The value of p<0.05 was set as a statistically significant criterion. Results The response rate was 35.7% (N=100). For both SM physicians and AH practitioners, the greatest research barrier was a lack of time. However, the leading research facilitators differed in the two professions. The top research facilitator for SM physicians was availability of research personnel, while availability of research mentoring was selected as a prime facilitator by AH practitioners. There were no differences in research interest between SM physicians (87.0%) and AH practitioners (95.5%, p=0.267). However, self-rated comfort reading research articles was higher in SM physicians (75.6±20.6) than AH practitioners (60.6±28.3, p=0.018). There were no differences in self-rated knowledge conducting research independently between SM physicians (70.2±18.6) and AH practitioners (63.4±24.6, p=0.163). Conclusion Lack of time was the top research barrier for both SM physicians and AH practitioners. Regarding research facilitators, having available time was the main facilitator for SM physicians while availability of mentoring was the leading facilitator in AH practitioners. Level of Evidence: 3

Authors: Chimera Nicole J , Merasty Danielle , Lininger Monica R 
Published: December 2022

Background The Canada Games are a national level competition held every two years alternating between Summer and Winter Games. Participation in elite level athletics, like the Canada Games, have an inherent risk of injury and illness. Purpose To analyze the incidence and characteristics of injuries and illnesses during Canada Games competitions from 2009-2019 (primarily) and to understand sex differences in odds of musculoskeletal injury for Summer and Winter Canada Games athletes (secondarily). Study Design Descriptive Epidemiology Study Methods Using a retrospective cohort, data were abstracted from medical incident reports generated during Canada Games from 2009 – 2019. Data were coded for body part injured and injury type or illness system; injuries were also categorized as acute or chronic. Results Across all 10 years of competition, 3160 injuries reported in 8710 male athletes and 3272 injuries reported in 8391 female athletes. Injury incidence was 362.8 and 389.9 and illness incidence was 47.8 and 64.5 per 1000 male and female athletes, respectively. Female athletes had a 1.12 (95% CI: 1.06; 1.19) greater odds of injury and 1.37 (95% CI: 1.20; 1.57) greater odds of illness compared to male athletes. Overall, injury (399.31 vs. 360.31; p < 0.001) and illness (68.67 vs. 47.30; p < 0.001) incidences were higher in Winter Games, compared to Summer Games, per 1000 athletes. When comparing male and female athletes participating in similar sports, sex specific differences exist in odds of both injury and illness. Conclusions Male and female athletes competing in Canada Games competitions demonstrate differences in injury and illness incidence and odds of injury. This suggests a need to examine if additional modifiable risk factors may exist, which could contribute to prevention strategies to reduce injury and illness during Canada Games competition.

Published: December 2022

Background Females have an increased incidence of musculoskeletal injuries compared to males. Sex differences in neuromuscular control has been widely studied regarding the dynamics and muscle activity during preplanned movements. While muscle activation patterns and movement biomechanics are understood to differ between sexes, it is not well understood how sex influences brain activity for lower extremity movement. Since the brain plays a vital role for voluntary movement and joint stability, it is important to understand the sex differences in brain function in order to better understand neuromuscular control associated with increased musculoskeletal injury risk in female. Hypothesis/Purpose The purpose of this study is to understand the differences in brain activation patterns between sexes during a simple active knee extension-flexion movement. It was hypothesized that females would demonstrate higher cortical activation in the somatosensory areas compared to males as a compensatory strategy. Study Design Cross-Sectional Study Methods Thirteen males and seventeen females who were healthy and physically active participated in this study (Male: 23.7±3.8 years, 74.5±13.5 kg, 172.3±6.4 cm; Female: 20.6±1.6 years, 65.4±12.8 kg, 163±6.1 cm). Functional magnetic resonance imaging data were obtained during a simple left knee extension-flexion exercise with their own leg weight while lying on the MRI table. The blood oxygen level dependent (BOLD) signals were compared between sexes. Results There was significantly greater activation in the visual cortices and premotor cortex in females compared to males during the studied movement. Males demonstrated significantly greater activation in the right cerebellum. Conclusion The results revealed sex differences in BOLD signal during simple knee extension-flexion movement. The results suggest that sex may be a biological factor in understanding brain activity associated with knee motor control. Level of Evidence Level 3

Authors: Greenberg Elliot , Greenberg Eric , Lawrence J. Todd , Ganley Theodore 
Published: December 2022

Background COVID-19 restrictions created a period of disrupted sports participation for youth athletes. The physical conditioning, sports training habits, and patterns of sports activity resumption upon returning to normal sports activity are currently unknown. Purpose/Hypothesis This study aimed to determine the extent to which youth athletes maintained their training levels during the early stages of the COVID-19 pandemic and understand the strategies that enhanced motivation and adherence to a training regimen while in isolation. A secondary aim was to analyze how youth athletes returned to activity and identify injuries associated with prolonged sports interruption. Study Design Observational / Survey Study Methods A survey designed to determine activity changes, type of organized instruction, and athlete preferences for training support were distributed by email using snowball sampling methodology to athletes 14-21 years old who were involved in competitive sports when pandemic restrictions were enacted. As sports activities resumed, a follow-up survey was distributed to the same respondents to identify feelings of preparedness, training habits, and injuries. Results Of the155 subjects (mean age 16.1 ± 2 years, 64.5% female) that completed the initial survey, 98% reported a stoppage of in-person sports participation and 70% decreased their exercise/training volume, with 41% (n=63) reporting > 50% reduction. Most athletes (86%) received instruction from coaches, with written workouts (70%) being most common; however, most athletes (70%) preferred instructor-led, group training sessions. Of the 43 subjects that completed the follow-up survey (34% response rate), there was an increase in athletic exposures compared to mid-pandemic levels, and 25% reported sustaining a sports-related injury shortly after resuming sports activities. Conclusions Pandemic-related sports restrictions resulted in a significant reduction in youth athlete training and conditioning. Coaches attempted to maintain training via the use of written workouts; however, athletes preferred instructor-led, group training sessions. There was a rapid resumption of sports activities, which may have contributed to the high rate of injuries in this study. Level of Evidence 3
Effects of Trigger Point Dry Needling on Strength Measurements and Activation Levels of the Gluteus Medius: A Quasi-Experimental Randomized Control Study
Authors: Schneider Eric , Moore Elizabeth S. , Stanborough Rob , Slaven Emily 
Published: December 2022

Background Latent trigger points have been identified as a source of impaired muscle function giving rise to a reduction in force production and alterations in muscle activation patterns and movement efficiency. There is limited investigation into the effectiveness of a treatment in reducing these clinical manifestations. Purpose To investigate whether the application of trigger point dry needling (TDN) to latent trigger points within the gluteus medius musculature affected strength measurements and muscle activation levels immediately following intervention. Design Quasi experimental, single group, pretest-posttest, randomized control study Methods A control and an intervention side were randomly assigned for each participant (N = 39). Hand held dynamometer (HHD) force measurements and raw surface electromyography (sEMG) amplitude readings were recorded during maximal volitional isometric contractions of the gluteus medius in two separate positions before and after application of TDN. Comparison of within and between group data were conducted. Results A statistically significant interaction between time (pre-TDN to post-TDN) and groups (intervention side and control side), p < 0.001 was found for HHD measurements in both positions. Post hoc analysis revealed a statistically significant difference (p < 0.001) for all comparisons in the side lying neutral (SL0) position, while statistically significant differences (p < 0.001) were found for pre and post-TDN measurements within intervention side as well as between the intervention and control side for post-TDN measurements in the side lying internal rotation (SLIR) position. For sEMG amplitude measurements, statistically significant differences were found only in the SL0 position for within group comparisons on the intervention side (p = 0.009) and for between group comparisons for post-TDN measurements (p = 0.002). Conclusion Application of TDN to latent trigger points within the gluteus medius can significantly increase gluteus muscle force production immediately following intervention while reducing the level of muscle activation required during contraction.
