BackgroundThe aim of the study was to analyze the relative and absolute reliability of intra-session comparisons of three repetitions in a protocol for assessment peak muscle strength in a knee extension and flexion exercise in competitive female soccer players.MethodsThe participants in this research are professional level female soccer players. Peak muscle strength was assessed with functional electromechanical dynamometry (FEMD) for the knee muscles with the following movements: knee flexion (FLE) and extension (EXT). Each movement was assessed at a speed of 0.4 m·s-1 unilaterally, recording peak muscle strength values in the concentric phase (CON) and an eccentric phase (ECC).ResultsNull differences (ES &lt; 0.19) were detected in the measurements of peak muscle strength of the extensors and flexors of the right and left knee in their concentric or eccentric phases. In the intra-set reliability measures, they reported acceptable absolute reliability (CV% &lt; 9.71) and extremely high relative reliability (ICC = 0.92–0.98).ConclusionIn relation to the results of this study, it can be concluded that the FEMD presents a high relative and absolute intra-series reliability for the evaluation of muscle strength in knee extension and flexion in female soccer players. These reported antecedents may facilitate a more specific evaluation of the function of the muscles of the lower limbs.

IntroductionNondestructive quantification of leaf chlorophyll content (LCC) of banana and its spatial distribution across growth stages from remotely sensed data provide an effective avenue to diagnose nutritional deficiency and guide management practices. Unmanned aerial vehicle (UAV) hyperspectral imagery can document abundant texture features (TFs) and spectral information in a field experiment due to the high spatial and spectral resolutions. However, the benefits of using the fine spatial resolution accessible from UAV data for estimating LCC for banana have not been adequately quantified.MethodsIn this study, two types of image features including vegetation indices (VIs) and TFs extracted from the first-three-principal-component-analyzed images (TFs-PC1, TFs-PC2, and TFs-PC3) were employed. We proposed two methods of image feature combination for banana LCC inversion, which are a two-pair feature combination and a multivariable feature combination based on four machine learning algorithms (MLRAs).ResultsThe results indicated that compared to conventionally used VIs alone, the banana LCC estimations with both proposed VI and TF combination methods were all significantly improved. Comprehensive analyses of the linear relationships between all constructed two-pair feature combinations and LCC indicated that the ratio of mean to modified red-edge sample ratio index (MEA/MSRre) stood out (R2 = 0.745, RMSE = 2.17). For multivariable feature combinations, four MLRAs using original or two selected VIs and TFs-PC1 combination groups resulted in better LCC estimation than the other input variables. We concluded that the nonlinear Gaussian process regression model with the VIs and TFs-PC1 combination selected by maximal information coefficient as input achieved the highest accuracy in LCC prediction for banana, with the highest R2 of 0.776 and lowest RMSE of 2.04. This study highlights the potential of the proposed image feature combination method for deriving high-resolution maps of banana LCC fundamental for precise nutritional diagnosing and operational agriculture management.

Published: February 2025

IntroductionPlant respiratory burst oxidase homologs (Rbohs) are essential in the generation of reactive oxygen species (ROS) and play critical roles in plant stress responses. Despite their importance, Rbohs in poplar species remain under-explored, especially in terms of their characteristics and functional diversity across different species within the same genus.MethodsIn this study, we employed bioinformatics methods to identify 62 Rboh genes across five poplar species. We analyzed the gene structure, physical properties, chromosomal distribution, and cis-elements. Additionally, we used qRT-PCR to examine the expression of PyRbohs (Populus yunnanensis Rbohs) under various stress treatments and yeast two-hybrid (Y2H) assays to confirm interactions with calcium-dependent protein kinases (CPKs).ResultsAll identified Rboh genes consistently contained six conserved functional domains and were classified into four distinct groups (I-IV). The number of Rboh members across poplar species was consistent with evolutionary patterns. These Rbohs exhibited relatively conserved amino acid lengths (832-989) and shared basic protein characteristics, including cell membrane localization. Chromosomal distribution analysis revealed an uneven distribution of PyRbohs across chromosomes, with abundant collinearity pairs among different plant species, indicating tandem segment duplications and a shared evolutionary origin within group members. Cis-element analysis identified stress-responsive and hormone signaling-related elements. qRT-PCR demonstrated the upregulation of PyRbohs under salt, drought, PEG, and ABA treatments. Protein interaction predictions using the STRING database identified potential functional mechanisms of PyRbohs, including interactions with CPKs. Y2H assays confirmed the interaction between PyRbohs and CPKs, suggesting that CPK binding might regulate PyRboh activity and ROS production.DiscussionOverall, these findings provide a comprehensive understanding of the evolutionary, structural, and functional diversity of poplar Rbohs. They highlight promising candidate genes for enhancing stress tolerance in poplar species and lay a foundation for future research on the molecular mechanisms underlying Rboh-mediated stress responses in poplar.

IntroductionDespite its relevance for health outcomes, only recently gender has begun to be explored in the scientific literature, typically using a rigid binary framework. To tackle this, the Stanford Gender-related Variables for Health Research (GVHR) was developed to analyze gender from a multidimensional perspective. We aim to use our Portuguese version of the GVHR and analyze its association with health outcomes, including perceived stress.MethodsTo this aim, 351 participants completed the GVHR scale, sociodemographic, and health information (including the Perceived Stress Scale, PSS-10). A Confirmatory Factor Analyses (CFA) was first performed, and logistic and linear regressions were used to explore the association between gender and health-related variables.ResultsAll measures of CFA showed appropriate goodness of fit. Regarding regression models, gender discrimination and higher levels of risk-taking were associated with binge drinking. Lower social support and risk-taking, and being male, were associated with being overweight. Regarding stress, it was positively associated with discrimination and work strain, while it was negatively associated with social support, emotional intelligence and risk-taking. Finally, discrimination and work strain were positively associated with mental health worsening and activity limitations, while social support was negatively associated with mental health worsening.DiscussionIn conclusion, by approaching gender from a multidimensional perspective we detected specific factors influencing health outcomes, showing that the relational aspects of gender are particularly relevant for mental health.

BackgroundHome-based palliative care is an ideal model for providing continuous, effective, and timely care at the patient’s home. However, the timely recognition of palliative home care needs remains a clinical challenge, and few studies have described the characteristics of palliative care needs and quality of life at home.ObjectivesTo identify the palliative home care needs of patients with advanced cancer and explore the influencing factors in addressing these needs.MethodsIn this cross-sectional study, convenience samples were collected from four cities in mainland China between May 2020 and November 2021. The revised Problems and Needs in Palliative Care-short version was used to evaluate palliative home care needs. The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C30 was used to evaluate the participants’ quality of life. We used SPSS version 23.0 for all statistical analyses. Descriptive statistics, Wilcoxon rank sum test, Spearman rho correlation independent t-test, and multiple linear regression were performed to analyze the data.ResultsCompleted the survey. The patients’ palliative home care needs were primarily related to physical symptoms, home health care services, and psychological issues. For items, the top three palliative home care needs were related to financial needs, “extra expenditures because of the disease” (75.9%), psychological issues, “fear of getting worse” (72.8%), and “fear of physical suffering” (67.9%). Multiple linear regression analysis revealed that 53.5% of palliative home care needs could be explained by the Karnofsky Performance Status and quality of life: physical, role, emotional, and financial difficulties dimensions.ConclusionThe palliative home care needs were associated with patients’ quality of life and financial difficulties. These findings may contribute to provide a framework for palliative home care service, and help to identify specific interventions.

IntroductionOnly 30%-40% of patients with first-episode depression recover after taking antidepressants. Acupuncture is a clinically recognized treatment for depression, but its effect on first-episode depression remains unknown. This randomized controlled trial is designed to investigate the efficacy and safety of electroacupuncture (EA) compared with escitalopram (ESC) in treating patients with mild to moderate first-episode depression.Methods and analysisThis is a multi-site, single-blind, randomized controlled trial with two parallel arms. A total of 204 eligible patients will be randomly allocated to two groups: the EA group (receiving EA treatment with placebo drugs) and the ESC group (receiving escitalopram and sham acupuncture treatment). Treatment will last 12 weeks, with 3 sessions per week for the first 8 weeks, decreasing to 2 per week for the remaining 4 weeks. The primary outcome will be the score of the 17-item Hamilton Depression Rating Scale (HAMD-17), and the secondary outcomes will include depression recovery rate, depression remission rate, Patient Health Questionnaire-9 (PHQ-9), 36-Item Short Form Survey Instrument (SF-36), and the dose and frequency of ESC. The Treatment Emergent Symptom Scale (TESS) will be used to assess all adverse effects. Full details of the statistical analysis plan for the primary and secondary outcomes will be described in this article.

Published: February 2025

PurposeAdolescents are experiencing rising rates of obesity, insufficient exercise, and sleep disorders. To provide a scientific basis for policymakers to develop targeted and evidence-based health behavior education and policies, this study employed structural equation modeling to design the Adolescent Health Behavior Checklist (AHBC).MethodsWe designed a draft 6-dimensional AHBC, which includes the dimensions of exercise, diet, personal responsibility, sleep, interpersonal relationships, and stress management. Each item is rated on a 5-point Likert scale, with higher scores indicating healthier behavior. Through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), we optimized the construct validity of the AHBC.ResultsThe optimal factor structure was first determined using EFA with 177 middle school students participating in the process. EFA suggested a hierarchical, 6-factor AHBC with good internal consistency (global Cronbach's alpha = 0.96). Using an independent sample of 349 middle school students, CFA confirmed the construct validity of the AHBC. The final model demonstrated a good fit: SRMR = 0.058, CFI = 0.990. Five out of six latent variables had factor loadings higher than 0.7, and 81% of the item-level factor loadings exceeded 0.7. Additionally, all latent variables had McDonald's omega values higher than 0.7, indicating acceptable convergent validity. Finally, factor correlations showed that the AHBC has good discriminant validity.ConclusionsThe AHBC is a 31-item checklist that assesses adolescents' all-around health behaviors, using a score of four as the benchmark value. The shortcomings of the current checklist are discussed, along with future theoretical and practical directions for improvement.

IntroductionDepression represents a significant mental health challenge among university students. Previous studies have revealed a relationship between benevolent childhood experiences (BCEs) and depression, but the roles of family relationships and sleep quality in mediating the link between BCEs and depression remain unclear. This study constructed a serial mediating model to examine whether family relationships and sleep quality mediated the relationship between BCEs and depression among Chinese university students.MethodsA total of 1830 university students from 25 universities in three provinces of China got recruited in this study. The assessment utilized the Benevolent Childhood Experiences Scale (BCEs-10) for childhood experiences, the Quality of Family Relationships Scale for family dynamics, the Pittsburgh Sleep Quality Index (PSQI) single-item for sleep quality, and the Center for Epidemiological Survey Depression Scale (CES-D-10) for depression. Correlation analyses and serial mediation modeling were conducted using SPSS 25.0 with PROCESS macro v3.4.1.ResultsBCEs, family relationships, and sleep quality scores were all found to be negatively correlated with depression scores (r = −0.46, −0.32, −0.47, respectively, all p &lt; 0.01). Family relationships, and sleep quality scores were positively correlated with BCEs scores (r = 0.31, 0.27, respectively, both p &lt; 0.01). There was a positive correlation between the family relationships score and sleep quality score (r = 0.22, p &lt; 0.01). Mediating analysis indicated that BCEs had a direct effect on depression (the direct effect accounted for 71.54%). Depression was affected by BCEs partly through three different pathways: the mediating role of family relationships (the mediation effect accounted for 8.50%), the mediating role of sleep quality (the mediation effect accounted for 16.40%), and the serial mediating role of both family relationships and sleep quality (the serial mediation effect accounted for 3.56%).DiscussionThe findings of this study demonstrated that family relationships and sleep quality partially mediated the association between BCEs and depression by serial mediating effects.Thus, improving sleep quality and family intervention may be effective measures to protect Chinese university students from depression.

Published: February 2025

BackgroundThe mental health and wellbeing of nurses, particularly pediatric nurses, have garnered attention due to the increased risk of mental health challenges associated with their demanding profession. These nurses are especially vulnerable, yet their mental wellbeing is often understudied.ObjectiveThis systematic review aims to identify and analyze key factors associated with mental health challenges among pediatric nurses and explore how these factors interact to influence their wellbeing.MethodologyThe review protocol was registered in PROSPERO (CRD42024553062) and adhered to PRISMA guidelines. A comprehensive search was conducted across six databases: PubMed Scopus, CINAHL, Web of Science, Medline, and Embase. Eligible studies included both qualitative and quantitative studies that examined factors linked to mental health challenges among pediatric nurses. The quality of the studies was appraised using the Mixed Methods Appraisal Tool (MMAT). Data extraction and synthesis involved qualitative content analysis to identify key factors.ResultsFive studies from China, Turkey, Greece, Canada, and Saudi Arabia were included. The key factors identified were high workload, poor work environment, limited resources, and strained interpersonal relationships, lack of support, irregular shift patterns, demanding roles, and financial strain. These factors were significantly associated with increased stress, burnout, anxiety, and depression among pediatric nurses. The interaction of these factors created a complex web influencing their mental health, with supportive work environments and adequate financial compensation mitigating some negative effects.ConclusionThis systematic review identifies high workload, poor work environment, limited resources, and strained interpersonal relationships, lack of support, irregular shift patterns, demanding roles, and financial strain as key factors impacting the mental wellbeing of pediatric nurses. These factors interact to exacerbate stress, burnout, anxiety, and depression. Effective interventions should include manageable nurse-to-patient ratios, adequate resource allocation, fostering a supportive work culture, flexible scheduling, targeted support for senior nurses, and improved financial compensation.

Published: February 2025

BackgroundDecubitus ulcers, also known as pressure ulcers, pose a significant public health challenge due to their substantial impact on morbidity, mortality, and healthcare expenditures.MethodsThe number and age-standardized rates (ASRs) of prevalence, death, disability adjusted life-year (DALY), years of life lost (YLL), and years lived with disability (YLD) at the global, regional, and national levels were acquired from the GBD 2021 database. Trends were evaluated based on the estimated average percentage change (EAPC) of ASRs. Additionally, data were stratified by socio-demographic index (SDI) quantiles, regions, countries, territories, and age groups.ResultsThe total number of decubitus ulcer cases increased from 300,442 in 1990 to 645,588 in 2021. The global ASR of prevalence decreased slightly from 8.25 to 7.92 per 100,000 persons, with most cases occurring in individuals aged 60 and older. Deaths due to decubitus ulcers rose from 16,622 in 1990 to 37,033 in 2021, while the global ASR of death declined from 0.53 to 0.46 per 100,000 persons. DALY due to decubitus ulcers increased, exhibiting significant variation across regions and age groups. A higher SDI was correlated with increased ASRs of prevalence (R = 0.488, p &lt; 0.001) and YLD (R = 0.495, p &lt; 0.001). Conversely, a higher SDI was correlated with lower ASRs of death (R = −0.329, p &lt; 0.001), DALY (R = −0.398, p &lt; 0.001), and YLL (R = −0.445, p &lt; 0.001).ConclusionThe global burden of decubitus ulcers has risen, with notable regional and age-related disparities. This study offers valuable insights for policymakers to optimize healthcare strategies and mitigate the public health impact of decubitus ulcers.

Published: February 2025

PurposeEsports is increasingly recognized as both a legitimate sport and profession. However, evidence on the health behaviors of esports athletes remains limited. Due to the nature of their activity, these athletes face occupational health risks associated with prolonged sedentary behavior, sleep deprivation, and excessive energy drink consumption. This study aimed to document the health behaviors of professional esports athletes.MethodsThis case study sampled athletes from Zhejiang Regans Gaming, who are full-time professionals competing at the elite level. Data were collected over three training days, with moderate-to-vigorous physical activity and sleep patterns monitored using the Apple Watch Series 9.ResultsAthletes trained for an average of 13 h daily in a seated position, engaging in only 35.6 ± 0.9 min of moderate-to-vigorous physical activity. The extended training hours led to delayed sleep schedules, with a typical bedtime of 3:05 a.m. Sleep quality was poor, with athletes averaging 45.2 ± 13.0 min awake in bed, 392.8 ± 13.9 min of total sleep, and a sleep efficiency of 89.7 ± 3.0%. Likely due to sleep deprivation, athletes consumed an average of 2 cups of coffee and 2.5 ± 0.4 bottles of energy drinks daily.ConclusionThis study offers firsthand evidence of the concerning health behaviors among Chinese elite professional esports athletes. Physical activity levels and sleep quality are notably poor, while energy drink consumption is prevalent. Team managers should monitor sleep quality and energy drink consumption, while governing bodies must recognize the long-term risks of excessive sedentary behavior in esports.
