ABSTRACT

Introduction
Although research supports selecting steeper routes to minimize metabolic rate (Ṁ) in mountain racers, the “steeper is cheaper” strategy has yet to be confirmed for slower, more typical graded walking speeds under cold stress.

Purpose
Confirm whether “steeper is cheaper” is true for typical graded walking speeds in individuals exposed to incremental cold stress.

Methods
Fourteen healthy, military-age adults (age, 24 ± 6 years; height, 1.72 ± 0.08 m; body mass, 72 ± 16 kg) completed four 20-min treadmill walks in three ambient temperatures (20, 10, and 0 °C) in light clothing (i.e., shorts, t-shirt, light gloves). Each walk involved five stages at incremental vertical speeds (0.00, 1.93, 3.86, 5.79, 7.79 m·min-1) but variable treadmill speeds (0.54, 0.72, 1.07 m·s-1). To verify the “steeper is cheaper” strategy, we compared Ṁ between treadmill speeds at matched vertical speeds in each temperature. We also tested if the 90% confidence interval around the mean percent paired difference between Load Carriage Decision Aid (LCDA) metabolic model predictions and measured Ṁ was within ±10%.

Results
Ṁ was significantly higher for the faster treadmill speed at matched vertical speeds in all but two comparisons at 20 °C, all but two comparisons at 10 °C, and all comparisons at 0 °C (p < 0.05). LCDA metabolic model predictions were statistically equivalent to measured Ṁ during graded walking at 20 °C (90% CI, −3.1, 0.6%) and 10 °C (−7.8, −2.6%) but not 0 °C (−16.2, −9.5%).

Conclusions
Route planners should recommend steeper but shorter routes to minimize Ṁ in individuals that walk in temperate-to-cold environments. The LCDA metabolic model provides accurate Ṁ predictions in lightly dressed individuals in temperatures down to 10 °C, but users should expect underestimated Ṁ in 0 °C or colder.

Introduccion: El trastorno de adicción al internet se ha convertido en una patología emergente con un impacto significativo en la conducta, salud física y mental Objetivo: Evaluar la asociación entre el trastorno de adicción al internet y la composición corporal en estudiantes de la Universidad Nacional del Centro del Perú (UNCP). Materiales y métodos: Se realizó un estudio analítico, observacional y transversal en estudiantes de la UNCP, entre 16 y 27 años, seleccionados mediante muestreo probabilístico aleatorio. Se evaluó la composición corporal medida a través de antropometría, y el trastorno de adicción al internet usando la Escala de Adicción al Internet (EAIL). Para evaluar la asociación, se estimaron las Razones de Prevalencia (RP) crudos y ajustados con sus respectivos intervalos de confianza al 95%.
Resultados: Se estudiaron 372 estudiantes universitarios, con un porcentaje de 66,1% de mujeres y 33,9% en varones, con una edad mediana de 20 años. Los resultados mostraron que el 52.4% presentaron trastorno de adicción al internet con respecto a la composición corporal. Se mostraron diferencias significativas en el pliegue tricipital. Además, el pliegue bicipital en mujeres fue mayor (14.93 mm ± 5.71) en comparación con los hombres (12.99 mm ± 6.47). Por otro lado, el porcentaje de grasa corporal en mujeres (27.51% ± 5.27) fue mayor al encontrado en hombres (18.47% ± 5.76). Existe relación significativa entre el trastorno de adicción al internet y la composición corporal, ya que un RP en el IMC de 5.25 significa que los jóvenes con trastorno de adicción al internet tienen una probabilidad casi cinco veces mayor de presentar bajo peso, sobrepeso y obesidad.
Conclusiones: Existe una asociación significativa entre la composición corporal con el trastorno de adicción al Internet en estudiantes universitarios de la UNCP.

O objetivo deste trabalho foi avaliar o potencial dos hidrolisados da biomassa de Arthrospira platensis na aceleração da germinação e no desenvolvimento das plântulas de tomate. Para os experimentos foi utilizado como substrato o papel germitest umedecido em água deionizada e sementes de tomate selecionadas. Inicialmente, verificou-se o embebimento da semente com os volumes de 0,5 e 1 mL de água deionizada. Após, para cada teste de germinação utilizou-se 54 sementes de tomate (n=4) embebidas com os hidrolisados ou água (controle). Um planejamento experimental foi empregado para otimizar as condições de concentração do ácido sulfúrico e tempo de hidrólise. A comparação de biomassa de 5 para 10% (m/v) foi avaliada para o desenvolvimento das plântulas e número de sementes germinadas. Ambos os volumes de embebimento foram satisfatórios e com isso optou-se pelo uso de 0,5 mL para os ensaios com os hidrolisados. Os números de sementes germinadas obtidas pelos ensaios do planejamento experimental indicaram que as melhores condições de hidrólise ácida foram a concentração de 1% (v/v) de H2SO4 por 30 min. O aumento de biomassa de 5 para 10% (m/v) na hidrólise demonstrou ser promissora para o desenvolvimento da radícula. Dessa forma, o uso da biomassa de A. platensis mostra-se como uma alternativa adequada para a estimulação da germinação e aumento do desenvolvimento da radícula do tomate.

Published: February 2025

Resumo: Este artigo defende o reconhecimento da relevância das variáveis geográficas para a prática do esporte eletrônico (esport). A discussão apresentada está situada na intersecção entre a geografia do esporte e a geografia da internet e é orientada por literatura anterior dos Game Studies. Os dados empíricos foram obtidos em um estudo longitudinal de jogadores semiprofissionais da cidade de Belém, na Amazônia, realizado entre os anos de 2017 e 2019, cujos resultados convergem com dados sobre a internet brasileira disponibilizados pelo Comitê Gestor da Internet no Brasil. A análise do material disponível indica a presença de mediações espaciais coerentes com os três eixos dos estudos da Geografia: físico, tecnológico e cultural. O espaço físico impõe dificuldades na distância em relação às cidades que são sedes de campeonatos, nacionais e internacionais, bem como para adquirir equipamentos. Essa última é também uma mediação técnica, pois tem reflexos sobre a qualidade do hardware utilizado pelos jogadores. A mediação tecno-espacial mais evidente diz respeito à qualidade das conexões de internet disponíveis nos diferentes locais. Os fatores da geografia humana incluem questões étnicas, de classe social e de gênero, bem como outros aspectos culturais. As primeiras foram identificadas na literatura pré-existente sobre esports, enquanto outros aspectos culturais apareceram de forma clara entre os dados do estudo apresentado.Palavras-chave: Esports; Espaço; Geografia.Abstract: This paper argues for the recognition of the relevance of geographical variables for the practice of electronic sports (esports). The discussion presented is situated at the intersection between Sport Geography and Internet Geography and is guided by previous Game Studies literature. The empirical data comes from a longitudinal study of semi-professional players from the city of Belém, in the Amazon, conducted between 2017 and 2019. The results of that study converge with data about the Brazilian internet provided by Brazilian Internet Steering Committee. The analysis of this material indicates the presence of spatial mediations coherent with the three axes of Geography studies: physical, technological and cultural. The difficulties coming from physical space are related to the distance between the location of the players and the cities that host national and international championships, as well as the centers from which hardware is acquired. The latter is also a technical mediation, as it constrains the quality of the equipment used by the players. The most prominent techno-spatial mediation is the quality of the internet connections available at different places. Human geography factors include ethnic, social class and gender issues as well as other cultural factors. The first and second were identified in the existing literature about esports, the latter figured in the results of the study presented.Keywords: Esports; Space; Geography.

Published: February 2025

Objective: To objectively quantify stifle effusion-synovitis in dogs with confirmed cranial cruciate ligament (CrCL) disease, with or without meniscal pathology, through radiographic assessment by investigating an association between severity of effusion-synovitis and cruciate and meniscal disease, and to establish a standardised quantitative radiographic measurement screening tool to predict severity of cruciate and meniscal injury. Methods: A total of 100 diseased stifles met the inclusion criteria and were assigned to either partial CrCL tear (PT), complete CrCL tear (CT), partial CrCL tear with meniscal pathology (PTM) or complete CrCL tear with meniscal pathology (CTM) groups. Quantitative measurement assessment was then performed to evaluate the percentage of cranial effusion-synovitis (CrES), caudal effusion-synovitis (CdES) and cranial fat pad compression. Three surgeons conducted a blinded review of 15 mediolateral stifle radiographs and were instructed to subjectively and quantitatively predict the degree of cruciate and meniscal pathology. Results: A significant difference of CrES between CT and PT groups (P=0.0173) and CTM and PT (P=0.0169) groups was identified. A significant difference in CdES between PT and CT groups (P=0.0015), PT and CTM groups (P=0.0041) and CTM and CT (P=0.0005) groups was identified. Quantitative measurement demonstrated improved sensitivity, specificity and agreement when compared to subjective assessment. Clinical significance: The results of this study propose that a quantitative radiographic measuring tool for predicting the severity of cruciate and meniscal disease may improve diagnosis of stifle pathology in a clinical setting and aid in pre-operative clinician decision making compared to subjective classification schemes.

Published: February 2025

In this study, a powder of two stable forms of copper oxide (Cu2O and CuO) was utilized for the photocatalytic degradation of Methylene blue (MB). Various attempts were made to determine the optimal conditions for degradation, including liquid-phase adsorption, initial dye concentration, catalyst weight loading, pH variation, H2O2, and NaI concentration. The results demonstrated that the photocatalytic degradation of MB by the Cu₂O-CuO mixture achieved efficiencies of 87.9% and 97.1%, respectively, in the presence of 0.01 M NaI and 2 mL of H₂O₂. A degradation rate of 97.92% was obtained at pH 12 after 2 hours. However, increasing the amount of dye is significantly reduced the degradation rate value, as the dye molecules blocked the light intensity required for photocatalyst activation. Liquid-phase adsorption studies showed that the adsorption efficiency of MB increased as its initial concentration decreased.Additionally, an acidic medium (pH 2) was found to be optimal for adsorption at 95.69%. The addition of NaI to the reaction medium significantly enhanced the adsorption of MB on the catalyst mixture. In addition, the powder X-ray diffraction (XRD) investigations showed the crystalline system of monoclinic CuO and cubic Cu2O. The morphological analysis using Scanning Electron Microscopy (SEM) revealed irregular shapes of nanostructures. Furthermore, investigations on the catalyst weight effect were investigated.
Physiotherapy under pressure: A cross-sectional study on the interplay between perfectionism, moral injury, and burnout
Authors: Biggs Daniel , Blackburn Laura , Black Cameron , Shanmugam Sivaramkumar 
Published: February 2025

Background
Given the escalating challenges for UK-based physiotherapists in workload pressures, budget constraints, staff shortages and patient wait times, the profession (of 65,000 registered physiotherapists) necessitates immediate attention to the health and well-being of the therapists. This pioneering study aims to examine perfectionism, moral injury, and burnout among UK-based physiotherapists across the NHS, private practice, sports, and academia.

Method
This cross-sectional study utilised an online survey and implementation of Structure Equation Modelling (SEM) to assess the interplay of perfectionism (Multidimensional Perfectionism Scale-Short Form), moral injury (Moral Injury Symptoms Scale-Healthcare Professionals), and burnout (Shirom-Melamed Burnout Questionnaire). Our sample size calculation represents the UK physiotherapy profession, utilising a 95% confidence interval with a 5% margin of error.

Findings
Our analysis conducted on (n = 402) UK-based physiotherapists reveals significant burnout levels, with 96% of participants presenting with moderate to high burnout scores. SEM revealed perfectionism and moral injury collectively accounted for a substantial 62% of burnout variability, highlighting their sequential impact on burnout manifestation.

Interpretation
With such high levels of burnout, urgent intervention is paramount. Elevated burnout presents challenges for the physiotherapy profession as staff retention, accurate and effective patient care, and overall health are severely impacted due to burnout. Recognising and addressing perfectionism and moral injury, such as through amendment or development of policy, becomes pivotal to mitigate its impact on individual and collective health.

Background
Substantial weaknesses and omissions of surgical informed consent are evident and the current elements of the surgical informed consent process are largely neglected in daily practice. This study aimed to assess surgical informed consent practice and associated factors among adult postoperative patients in public hospitals of Mekelle, Tigray, Ethiopia.

Methods
Institution based cross-sectional study was conducted among 314 adult postoperative patients in public hospitals of Mekelle, Tigray, Ethiopia. Participants were selected using systematic random sampling. A pretested interviewer-administered questionnaire was used to collect data. Descriptive, Descriptive, bivariate and multivariable logistic regression analyses were performed using statistical package for social science version 27.

Result
Only 35.8% (CI 95%, 30.6, 41) of the respondents were identified to have received the recommended (6 or more) components of surgical informed consent. Educational level [AOR 5.76 (1.02, 32.6)], timing of surgical informed consent delivery [AOR 3.27 (1.5, 7.11)], qualification of counselor who took surgical informed consent them [AOR3.185 (1.21, 8.38)], hospital type [AOR 2.85 (1.26, 6.46)], and duration of counseling [AOR 6.9 (3.33, 14.3)] were statistically significant at P<0.05.

Conclusion
Majority of participants did not receive comprehensive information during the surgical informed consent process in the study hospitals. To improve the delivery it is suggested that health professionals; create rapport with patient, spend more time during counseling.

Purpose
Understanding factors influencing clinical biomarkers is important for the prevention of chronic disease. This study aimed to estimate transitions of biomarker status from childhood to adolescence and to identify determinants of biomarker status in early life in a prospective children cohort.

Subjects and methods
Our sample comprised 1295 children participating in the baseline (2007/08) and second follow-up examination (2013/14) of the multi-center IDEFICS (Identification and prevention of Dietary- and lifestyle-induced health EFfects In Children and infantS)/I.Family study. Clinical blood biomarkers including glycated hemoglobin A1c (HbA1c), high-density lipoprotein cholesterol (HDL-cholesterol), triglycerides, C-reactive protein (CRP), interleukin 6, ferritin, leptin and insulin-like growth factor 1 (IGF-1) were repeatedly measured in 2007/2008 (age range: 3.0 to <10.0 years) and in 2013/2014. Latent transition analysis was used to estimate biomarker statuses and transition probabilities; determinants of biomarker status were estimated using mixed-effects models.

Results
Four distinct biomarker statuses were identified: (1) “normal” (all biomarkers low/medium; except HDL-cholesterol; reference), (2) “low leptin/IGF-1/HbA1c”, (3) “dyslipidemia/high leptin” and (4) “inflammation”. Children classified as “low leptin/IGF-1/HbA1c” at baseline were most likely to stay in this status (89.8%) or to change to the “normal” status (10%) during follow-up. Compared to “normal” children, children classified as “low leptin/IGF-1/HbA1c” were less likely to have a family history of diabetes (0.26 [0.08;0.86]; odds ratio (OR) and 95% confidence interval) or hypertension (0.53 [0.29;0.99]) and the children (0.32 [0.27;0.38]) as well as their mothers (0.93 [0.88;0.98]) had a lower BMI. Children from families with low/medium education had a 55% [9%-119%] higher risk of being in the “dyslipidemia/high leptin” and 49% [1%-121%] higher risk of being in the “inflammation” status as compared to children in the “normal” status. Membership in a sports club reduced the latter risks by 28% [2%-47%] and 40% [17%-56%], respectively.

Conclusions
European children showed distinct phenotypes for the investigated biomarkers. Especially parental characteristics like a family history of diabetes or hypertension, a high maternal BMI, or low/medium education were associated with unfavorable biomarker status in children.
Estimation of supply and demand for public health nurses in Japan: A stock-flow approach
Authors: Taira Kazuya , Horikawa Masanao , Itaya Takahiro , Hosokawa Rikuya , Shiomi Misa 
Published: February 2025

Public health nurses (PHNs) play a central role in community health in Japan, and the number of certified PHNs has decreased since 2011. However, thus far, no study has estimated the supply and demand of PHNs in the coming years. The present study aimed to estimate the future balance between supply and demand for PHNs in Japan. This simulation study adopted a stock-flow approach using data from a survey of local governments, log data from a recruitment information website, and government statistics. The supply was estimated by adding up the numbers of newly hired PHNs and job changers to that of PHNs from the human resource pool. The demand was estimated from the number of PHNs needed in the future calculated by demographics assumed to affect the demand for PHNs. At the current job change rate to PHNs, the gaps between future supply and demand of PHNs were expected to be −494 to −50 in 2025, −1,007 to −435 in 2030, and −772 to −330 in 2035. If the job change rate would be 1.5 times, the gaps were estimated to be 285 to 729 in 2025, −431 to 141 in 2030, and −182 to 260 in 2035. If the job change rate would be 2.0 times, the supply was sufficient for all estimated years. The number of PHNs working in Japanese local governments is estimated to decline until 2035, resulting in a shortage. Policy makers should consider early measures to adjust the future number of PHNs.
