Introduction

À ce jour, la surveillance du vapotage chez les Canadiens (qu’ils utilisent des produits de vapotage contenant de la nicotine ou n’en contenant pas) a largement été analysée en fonction de l’âge et de l’usage du tabac, mais il n’existe aucune étude, à l’échelle nationale, qui soit représentative d’un large éventail de caractéristiques. Notre étude a permis de caractériser les Canadiens de 15 ans et plus qui vapotent en fonction de leur usage du tabac.

Méthodologie

Nous avons utilisé les données de l’Enquête sur la santé dans les collectivités canadiennes de 2020 (taille de l’échantillon analytique non pondéré : 28 413 répondants) pour l’analyse du vapotage au cours des 30 derniers jours en fonction du tabagisme (fumeur, ancien fumeur et non-fumeur/n’ayant jamais fumé). Une méthode d’analyse comparative entre les sexes et les genres Plus (ACSG Plus) nous a permis de sélectionner les caractéristiques individuelles pour l’analyse. Des statistiques descriptives ont contribué à l’analyse des résultats en fonction de chaque caractéristique et nous avons élaboré des modèles de régression logistique multivariée pour identifier les facteurs significatifs associés à chaque catégorie de vapotage au cours des 30 derniers jours en fonction du tabagisme, à partir des données pondérées.

Résultats

En 2020, 2,0 % (605 000) des Canadiens de 15 ans et plus ont déclaré à la fois vapoter et fumer (double usage), 1,2 % (372 000) ont déclaré vapoter et être ancien fumeur et 1,1 % (352 000) ont déclaré vapoter et n’avoir jamais fumé ou être non-fumeur. À l’intérieur de chaque catégorie de vapotage au cours des 30 derniers jours en fonction du tabagisme, certains sous-groupes de population présentaient des risques plus élevés : les jeunes et les jeunes adultes, les hommes et les personnes souffrant d’un trouble de l’humeur ou d’un trouble d’anxiété présentaient un risque plus élevé de double usage; le vapotage et le fait d’être ancien fumeur ont été associés à une auto-identification comme homme, à un trouble de l’humeur ou d’anxiété et à la province ou région; et enfin les jeunes et les jeunes adultes, les hommes et les personnes ne faisant pas partie d’une minorité visible présentaient un taux plus élevé de vapotage associé au fait de n’avoir jamais fumé ou d’être non-fumeur.

Conclusion

Cette analyse portant sur les Canadiens qui vapotent en fonction de leur usage du tabac a permis d’identifier des sous-groupes de population à forte prévalence et nous informe sur la composition des populations qui vapotent en fonction de plusieurs caractéristiques, ce qui nous permet d’approfondir notre compréhension des Canadiens qui adoptent des habitudes de vapotage.
Об истории, предмете и задачах российского науковедения
Authors: Кочетков Дмитрий
Published: November 2024

В условиях современных вызовов, стоящих перед российской наукой, формирование науковедения как интегрированного научного направления приобретает особую актуальность. Цель данного исследования — определить контуры развития российского науковедения на современном этапе, основываясь на результатах сравнительно-исторического анализа предметной области. В ходе анализа автор рассматривает науковедение как трансдисциплинарную область, которая изучает универсальные закономерности производства научного знания и научно-технологического развития с использованием методов, возникших в различных дисциплинах, и в их взаимосвязи с социальным, экономическим, политическим, культурно-историческим и природным контекстом. Исследование выявило три ключевые проблемы современного российского науковедения: 1) дивергенция российской и мировой исследовательской повестки в области науковедения; 2) разрыв между академическим науковедением и процессом принятия решений в области научно-технической политики; 3) отсутствие науковедения как направления в системе специальностей и направлений подготовки высшего образования и научных специальностей. Ключевым фактором успеха является постепенное преодоление дисциплинарных границ в рамках науковедения как единого научного направления. Первым шагом в этом направлении должно стать включение науковедения в номенклатуру научных специальностей, перечень специальностей и направлений подготовки высшего образования, а также разработка единого теоретико-методологического инструментария и создание междисциплинарных координационных механизмов. Трансдисциплинарность является основным инструментом для достижения этой цели.

Authors: Shovin V.A.
Published: November 2024

The role of the article is to develop a new algorithm (method) of factor analysis, which includes an advanced model of relationships between factors and initial variables, when the model takes into account not only linear terms, but also quadratic ones, i.e. expansion to the second degree. Such a model belongs to the class of nonlinear structural models. The calculation algorithm allows you to build a clarifying model, study the influence of the nonlinear component in the factor influence. Also, a corresponding program with a graphical user interface has been developed, capable of performing quadratic factor analysis of new data by loading new data. This article is of both applied and fundamental nature. The program and the corresponding computational algorithm have been tested on real data, which made it possible to compare previous calculations based on this data for linear factor analysis with the quadratic one proposed in the article. Based on numerical methods of nonlinear optimization with conditions, a method for finding an estimate of the parameters of nonlinear structural equations has been developed. Minimization of residuals of the structural equations of the model has been chosen as a criterion for the optimal parameters of the structural equations. The given method was tested for the model of quadratic factor analysis of arterial hypertension at the initial stage with the corresponding software implementation.

Published: November 2024

This research analyzes the relationship between political stability, renewable energy utilization, economic progress, and tourism in Indonesia from 1990 to 2020. We employ advanced econometric techniques, including the Fourier Bootstrap Autoregressive Distributed Lag (ARDL) approach and Fourier Toda-Yamamoto causality testing, to ensure the robustness of our results while accounting for smooth structural changes in the data. The analysis uncovers a long-term equilibrium relationship between tourism and its fundamental determinants. Our research reveals significant positive impacts of political stability and renewable energy consumption on tourism in Indonesia. A stable political environment creates a favorable climate for tourism development, instilling confidence in both domestic and international tourists. Promoting renewable energy usage aligns with sustainable tourism practices, attracting environmentally conscious travelers. Furthermore, our findings demonstrate a bi-directional causal relationship between these variables over time. Changes in political stability, renewable energy consumption, and economic growth profoundly influence the tourism sector, while the growth of tourism itself can also stimulate economic development and foster political stability. Our findings underscore the need for environmentally sustainable and politically stable tourism policies. Indonesia’s tourism sector can grow sustainably with renewable energy and stability. Policymakers can develop strategies with tourism, political stability, renewable energy, and economic prosperity in mind.

Authors: Astuti Komang Puji , Sasmana I Gede Aswin Parisya , Subrata I Made
Published: November 2024

Introduction: Type 2 diabetes mellitus (T2DM) has become a global concern with a prevalence reaching 6.28% worldwide which is characterized by insulin resistance, chronic increases in blood glucose, and contributes to the development of various diseases with high mortality. Several dietary approaches have been developed to improve T2DM, including the Mediterranean diet, which has not been widely evaluated.
Methods: This literature was created to evaluate the effect of the Mediterranean diet on glycemic control and insulin sensitivity in T2DM patients. Methods: A systematic review and meta-analysis was used to create this literature, including valid clinical studies and retrieved from PubMed, ScienceDirect, and Cochrane databases until July 2023. A total of 7 studies involving 1395 participants were included and analyzed using Review Manager and R to evaluate control glycemia, insulin resistance, and Body Mass Index (BMI).
Results: The results of the study showed that the Mediterranean diet was able to reduce blood glucose levels significantly (MD -0.69; 95%CI: -1.08 to -0.29; I2 = 67%; p: 0.0006), both fasting and non-fasting blood glucose. Apart from that, this diet can also reduce HbA1c significantly compared to the control diet (MD -0.45; 95%CI: -0.68 to -0.21; I2 = 63%; p: 0.0003). In reducing insulin resistance, the Mediterranean diet can significantly reduce HOMA-IR with a difference in protective ratio of -0.82 (95%CI: -1.29 to -0.36; I2 = 79%; p=0.0005). Moreover, the Mediterranean diet can reduce BMI in T2DM patients (MD: -0.66; 95%CI: -0.98 to -0.34; I2 = 44%; p<0.00001) which can certainly prevent further severity and complications of this disease.
Conclusion: The Mediterranean diet can reduce fasting, non-fasting blood glucose levels, HbA1c, HOMA-IR, and BMI in T2DM

Published: November 2024

The types of natural food consumed by fish can vary according to their species and its age level. The purpose of this study was to determine the types of organisms feed by Apogonidae fishes by observing their gut contents and to determine the type of feeding habits of these fishes. This research was conducted at two sampling sites within Gilimanuk Bay, Bali. Specimen collection was conducted in the morning (07.00 am) using a scoop net while scuba diving. We successfully collected 32 individual Apogonidae, which consist of eight species. Each sample was dissected and the contents of the stomach were removed from the esophagus to the intestine. The stomach contents were preserved using 4% formalin, and then the samples were observed under a binocular microscope with 40x magnification. The results showed that the highest composition of food species found as the main food was the Copepod of 59.86% which was fed by Sphaeramia nematoptera, Cheilodipterus artus, Fibramia thermalis, Pterapogon kaudernii, Zoramia leptacantha, Rhabdamia gracilis, and Ostorhichus hoevenii, Bacillariophyceae by 31.97% were feed by S. nematoptera, C. artus, O. hartzfeldii, F. thermalis, P. kauderni, Z. leptacantha, R. gracilis, and O. hoevenii. The other class of plankton only made up a small part of the food composition of the Apogonidae fishes, which is as much as 8.16%. Based on our results, we conclude that Apogonidae fishes in Gilimanuk Bay were plankton feeders where all the food found comes from phytoplankton and zooplankton organisms.

Seagrass, a flowering marine plant, has adapted to thrive in shallow seas where its stems grow along the substrate. Seagrass meadows offer numerous benefits due to the mutual interaction between seagrass and marine biota. The primary objective of this study was to determine the precise composition of the epifauna community and establish the relationship between epifauna abundance and seagrass density. The research was conducted between October and December 2022. Purposive random sampling was employed as the research methodology, with three stations selected at each research location. The findings revealed the presence of nine seagrass species, namely Cymodocea rotundata, C. serrulata, Enhalus acoroides, Halodule pinifolia, H. uninervis, Halophila ovalis, H. minor, Thalassia hemprichii, and Syringodium iseotifolium. The highest species density, recorded at Prapat Agung Beach, was observed in the H. uninervis type with a density of 216 ind/m2. Conversely, at Segara Ayu Beach, the highest species density was found in the C. rotundata type, with a 320/m2 density. Segara Ayu Beach exhibited the highest epifauna diversity, scoring 3.46 in the high category. Additionally, it displayed the highest epifauna uniformity, with a score of 0.92 in the high category. Prapat Agung Beach had the highest epifauna dominance index, scoring 0.19 in the low category. The correlation analysis between seagrass density and epifauna abundance yielded a correlation coefficient (r) of 0.779, indicating a strong relationship. The ANOSIM test results indicated a significant difference in the abundance of epifauna, with an R-value of 0.9657 and a ???? value of 0.0001.

Published: November 2024

Chronic kidney disease (CKD) is a growing concern in children, leading to significant health complications. While angiotensin-converting enzyme (ACE) inhibitors are used in adults with CKD to slow disease progression, their effectiveness in pediatric patients remains unclear. This systematic review aimed to evaluate the existing research on the efficacy and safety of ACE inhibitors in delaying the progression of CKD in children. A systematic search of electronic databases like PubMed, MEDLINE, Science Direct, and Scopus was conducted. Two independent reviewers screened and extracted data from eligible studies. Six studies including 519 participants in total, of which 209 (40%) were females, were included in the study data. The follow-up duration ranged from 6 months to 7.75 years. ACE inhibitors decreased the albumin excretion rate in daily urine and the albumin creatinine ratio in daily urine dropped with renoprotective therapy. Management with ACE inhibitors maintained graft function in children with chronic allograft dysfunction, with enhancement of creatinine clearance in children undergoing renal transplantation. To this day, ACEIs represent the greatest known means of slowing the advancement of pediatric nephropathy and chronic non-diabetic renal disorders. Prospective comparison research and trials of combination therapy with ACEI and angiotensin receptor blocker should be promoted in children. A multicenter trial would be necessary due to the minimal number of patients.

Authors: Dona Rahma , Jasril  , Hendra Rudi , Frimayanti Neni
Published: November 2024

This study investigated the potential of chalcone derivatives as antimalarial agents. The structures of the chalcone derivatives were designed by including amino substituents on acetophenone and methoxy variants on benzaldehyde. As a result, three amino chalcone derivatives (1-3) were synthesized. The synthesis was conducted by performing the Claisen-Schmidt condensation reaction with 40% NaOH as the base catalyst, resulting in a yield ranging from 66% to 83%. In addition, the structures of the compounds were determined by FTIR, MS, and 1H-NMR spectroscopy techniques, confirming that the compounds possess structures that align with the desired molecular structure. The antimalarial activity test was conducted by inhibiting the process of heme polymerization into hemozoin (β-hematin) in a controlled laboratory setting. This process is one of the key targets of antimalarial medication therapy. Among the compounds, compound 2 exhibited superior antimalarial activity, with an IC50 value of 118.15 μg/mL, in comparison to the positive control hydroxychloroquine sulphate (IC50 value of 184.98 μg/mL). The inhibitory action of heme polymerization in the synthesis of hemozoin was influenced by the location and quantity of methoxy groups in the chalcone molecule, as observed in this work.
Modelling of Dividend Payout Policy for Polish Public Companies
Authors: Kompa Krzysztof , Witkowska Dorota
Published: November 2024

Purpose: The purpose of this research is to identify drivers of dividend payouts in energy companies listed on the Warsaw Stock Exchange (WSE) in the pre-COVID-19 pandemic decade, taking into account potential determinants such as general economic situation, company’s financial efficiency, value of assets, lagged dividend payout, earnings, ownership of the company – main shareholders and structure of statutory bodies including women presence. Design/methodology/approach:
Correlation analysis and pooled regression models to determine the potential determinants of payouts are used. Firms' financial performance is reflected by selected individual financial ratios and a specially constructed vector synthetic measure VSMD. Findings: Findings reveal that dividend payouts of energy companies in Poland are irregular. Dividend payments significantly depend on firms’ financial efficiency, the size of their assets, lagged dividend payouts and ownership model, while the gender structure of statutory bodies has no impact on dividend payouts. The dividend payment decisions are implied by the current economic situation. Research limitations/implications: Limitations arise from the longitudinal sample design and data selection. Only Poland is considering with rather small WSE market, and the study concerns 9 companies described by 14 financial ratios (already selected) and set of variables for each year in 10 years
timespan. Our VSMD measure needs pattern and anti-pattern which requires data from the entire market to be determined. Thus, the list of diagnostic variables cannot be simply copied for different “national” markets. Originality/value: This study contributes to research on the determinants of dividend policy. It introduces to the investigation the author's synthetic measure of firm financial efficiency. Explains dividend payments in Polish energy companies in the period 2010-2019 proposes a consistent baseline for research after the pandemic and after the war in Ukraine.

Published: November 2024

An ecological and cenotic analysis of Hydrocotyle vulgaris, a rare sub-Atlantic species, which is in Ukraine on the eastern border of distribution and is listed in the Red Data Book of Ukraine, was carried out. The article presents data on the distribution of the species in Ukraine, obtained on the basis of personal data, literary materials and the database of the National Biodiversity Information Network (UkrBin). Six new localities of the species are presented. It was discovered that H. vulgaris occurs on the territory of four regions. It is most widespread on the territory of the Volyn and Lviv region. The locality in the Ternopil region should be considered as lost. For the first time, the locality on the territory of the Rivne Nature Reserve, which is currently the easternmost in Ukraine, is given. The phytocenotic peculiarities of the species on the territory of Ukraine and neighboring countries has been established. Types of vegetation with presence of the species were defined. According to the analysis of literary sources, the species is widespread on peat bogs, marshy meadows, in the zone of periodic flooding along the banks of mesotrophic reservoirs, on alder bogs with peaty, moderately acidic, silty sands. In general, the species was noted as part of 6 classes and 9 alliances, presented by woody, shrubby and herbaceous vegetation. Based on personal data, it was found that H. vulgaris occurs in communities of three classes, four alliances and four associations on the territory of Ukraine. The ecological and coenotic study of H. vulgaris made it possible to establish the peculiarities of the ecology of this species. It was established that the leading edaphic factors affecting the distribution of the species are humidity and soil composition. It is limited to nutrient-poor non-saline slightly acidic soils, mainly peaty or sandy. H. vulgaris belongs to the species that are affected by the changing water regime and is limited to places where temporary flooding is observed. It prefers habitats with reduced interspecific competition. Taking into account this feature, it is proposed to introduce regular mowing as a factor that prevents civilization of the territory and stimulates the vegetative renewal of the populations of the species. In tree and shrub communities, it is proposed to carry out selective felling. In order to preserve the populations of the species, it is also necessary to maintain the bare, well-moistened areas. In nearby agricultural lands it is necessary to avoid fertilizers.

Species identification was conducted under laboratory conditions according to scientific requirements. The list of species of this family was formed from taxa according to Nieukerken et al. (2011). Entomological collection of Lepidoptera was conducted in accordance with nature conservation legislation norms.
It was established that in 2021, 8 species were identified (168 individuals), in 2022 – 5 species (71 individuals), and in 2023 – 6 species (84 individuals). The studied insects belong to 6 genera: Leptidea, Anthocharis, Pieris, Pontia, Colias, Gonepteryx.
Based on the analysis of relative abundance, it was determined that Pieris rapae was the most abundant species throughout the studied years, while Pieris brassicae, Pieris napi, Colias hyale, and Gonepteryx rhamni were common species, and Leptidea sinapis, Anthocharis cardamines, Pontia daplidice, and Colias croceus were rare. For a detailed study of the Pieridae family and conducting comprehensive ecological-faunistic insect identification, we plan to conduct annual entomological surveys of fauna of Ukraine. These data can be used for the further analysis of the changes of species diversity of this family taking into account biodiversity conservation.

Published: November 2024

An experimental campaign has been conducted to assess the effect of total pressure inlet distortion on a single stage axial compressor. Different grid sectors have been installed in front of the inlet of the compressor to generate the distortion. Pressure measurements and particle image velocimetry have been used to characterize the impact of the distortion on the flowfield and the performance of the compressor. The broad range of porosity and angular extension of the grid sectors has allowed identifying four different flow regimes characterised by a different response of the compressor. In particular, the low porosity introduces flow regimes which have been never encountered in typical distortion tests restricted to high-porosity grids. In two of these regimes, it has been possible to identify a new scaling of the stall margin versus a new distortion index based on more solid physical ground than already existing indices such as the DC60. The experiments have also shown that for each of these four flow regimes behind the grid different rotating stall features (spike stall or modal stall) appear. A scaling of the stall dynamic has been finally provided thanks to analysis of unsteady casing static pressure signals acquired during the stall transient.
Power Generation Characteristics of Disk-Shaped Magnetohydrodynamic Generator Driven by Rotating Detonation

Published: November 2024

The power generation characteristics of a disk-shaped magnetohydrodynamic generator driven by rotating detonation with potassium-seeded hydrogen–air mixture are examined via quasi-two-dimensional numerical simulations. For unburned gas injection in the outward and inward directions, the rotating direction of the detonation wave is set so that the azimuthal velocity enhances the radial electromotive force. The simulation results show that the power output in the outward flow configuration exceeds that of the inward flow configuration. In the outward flow configuration, the radial gas velocity around the contact surface is the main contributor to the power generation, while in the inward flow configuration, the low gas velocity in almost the entire region and the vortices around the contact surface lead to poor power output. The characteristics in not only the power output mode but also the power input mode in which the voltage is applied externally between the electrodes are investigated. Under the positive load voltage, high enough for providing negative current, the Lorentz force occurs in the same direction as the propagation of the detonation wave; otherwise, the Lorentz force is induced in the opposite direction of the detonation wave.
Reinforcement Learning for Submodel Assignment in Adaptive Modeling of Turbulent Flames

Published: November 2024

Reinforcement learning (RL), an unsupervised machine learning approach, is innovatively introduced to turbulent combustion modeling and demonstrated through the automated construction of submodel assignment criteria within the framework of zone-adaptive combustion modeling (AdaCM). In AdaCM, the appropriate combustion submodel—whether the cost-effective species transport model or the advanced transported probability density function (TPDF) method—is adaptively assigned to different regions based on a criterion crucial for performance. The use of RL avoids the extensive manual optimization that involves repetitive calculations and struggles to account for multiple factors. Specifically, RL agents observe local variables as the state and determine the appropriate submodel through a policy. The policy is refined to maximize a reward measuring both accuracy and efficiency through the interaction between RL agents and the AdaCM solver. The methodology is demonstrated for a turbulent non-premixed jet flame, and a sophisticated RL criterion exhibiting a nonlinear and nonmonotonic dependency on the two-dimensional state of mixture fraction and Damköhler number is learned. The AdaCM with the trained criterion provides predictions that are nearly indistinguishable from those obtained using the TPDF method for the whole computational domain, while substantially reducing the computational cost with the speedup of 3.4 and only 22% of cells for TPDF.
Application of Gauss’s Principle to the Classical Airfoil Lift Problem
Authors: Peters David A. , Ormiston Robert A.
Published: November 2024

This paper examines the application of Gauss’s principle of least constraint to the classical problem of the lift of a two-dimensional airfoil in ideal, incompressible fluid flow, including the role of the empirical Kutta condition that determines the airfoil circulation in classical theory. Gauss’s principle demonstrates that the fluid pressure field consists of two components: a constraint pressure field that enforces the continuity and nonpenetration constraints and an impressed pressure field of arbitrary strength that satisfies but does not influence any constraints. The analysis shows that a flow solution that minimizes the difference between the acceleration and the impressed pressure gradient is a valid solution of Euler’s equation. Furthermore, Gauss’s principle proves that ideal potential flow airfoil theory is incomplete and that a first principles closure condition cannot exist within potential flow. This reaffirms the view that an external, empirical condition is needed to complete classical airfoil theory, i.e., the Kutta condition. The paper also investigates and disproves a new variational theory of lift developed from Hertz’s principle of minimum curvature that is claimed to provide a closure condition based on first principles to replace the empirical Kutta condition of classical airfoil theory.

Oyster mushroom is a commodity that is in high demand in the community. Oyster mushroom production in Indonesia is decreasing year after year as wood sawdust, which is often used as a media for oyster mushrooms, becomes increasingly difficult to get. Bamboo has a nutrient content similar to wood sawdust; therefore, bamboo sawdust can be utilized as a media for growing oyster mushrooms. The aim of this research was to find the best mixture of bamboo and wood sawdust for the growth and yield of oyster mushrooms (Pleurotus ostreatus). This research was carried out from July to October 2023 at Lampung State Polytechnic. This study used a randomized block design with one factor that was repeated four times. The following treatments were used: C0 = 100% wood sawdust, C1 = 90% bamboo sawdust + 10% wood sawdust, L2 = 80% bamboo sawdust + 20% wood sawdust, C3 = 70% bamboo sawdust + 30% wood sawdust, C4 = 60% bamboo sawdust + 40% wood sawdust, and C5 = 50% bamboo sawdust + 50% wood sawdust. The collected data was analyzed using analysis of variance (ANOVA) and then evaluated with LSD test at the 5% level. The results of this research were that the treatment of C5 = 50% bamboo sawdust + 50% wood sawdust gave the best results on the parameter of the mycelium growth rate, the time of the fruit body initiation (FBI), the number of hoods, the diameter of the hood, the thickness of the hood, the harvest, the harvest weight per baglog, and the total harvesting per plot.

Published: November 2024

OBJECTIVE: We sought to develop recommendations to inform a framework for comprehensively assessing upper and lower limb pain in athletes including the key assessment items sports physiotherapists should consider.

DESIGN: Real-time Delphi.

METHODS: We recruited sports physiotherapists who were currently working with athletes through the International Federation of Sports Physical Therapists and Irish Society of Chartered Physiotherapists. Participants voted on 86 pain assessment items chosen using best available evidence. The real-time Delphi method facilitated independent anonymous voting, commenting, and immediate review of consensus. Participants indicated level of agreement for inclusion in an upper and lower limb athlete pain assessment framework on a 6-point Likert scale from strongly disagree to strongly agree, and how often they are/will be required in practice on a 5-point scale from never to always. Criteria for consensus agreement and inclusion were (1) >70% sports physiotherapists voting agree/strongly agree AND (2) median vote selected by physiotherapists was agree or strongly agree.

RESULTS: Forty-one sports physiotherapists (female, n = 20; male, n = 21), visited the survey an average of 5.3 times (±5), resulting in a completion rate of 98%. Sixty-four assessment items (neurophysiological, n = 20; biomechanical, n = 15; affective, n = 8; cognitive, n = 3; socioenvironmental, n = 10; general assessment aspects of assessment, n = 8) met the criteria for consensus. Frequency of use in practice was always for 28 items often for 32 items and sometimes for 4 items.

CONCLUSION: We have presented stakeholder-generated recommendations and priorities for assessing athletes’ pain. J Orthop Sports Phys Ther 2025;55(1):45-55. Epub 22 November 2024. https://doi.org/10.2519/jospt.2024.12807
