Objective: To explore the effects of sleep on subsequent day physical activity (PA) in children and adolescents, so as to provide a reference for refining PA intervention strategies and further investigating their underlying mechanisms. Methods: Through searching databases including Web of Science Core Collection, PubMed, EBSCOhost, ScienceDirect, Cochrane Library, CNKI, Wanfang and VIP cross sectional, cohort and experimental studies on sleep and subsequent day PA among children and adolescents were identified, with the searching period spanning from database inception to June, 2025. Based on the characteristics of the included literature, two sleep variables[sleep duration (SD) and sleep efficiency (SE)] and three physical activity variables[moderate to vigorous physical activity (MVPA), light physical activity (LPA), and total physical activity (TPA)] were selected. The relationship between these two types of variables was analyzed for pooled effect sizes using Stata 17.0. Results: A total of 14 studies were included, with 64.3% published in 2018 or later, involving 11 361 children and adolescents from 17 countries. Meta analysis results showed that both SD ( ES=0.04, 95%CI =0.01-0.07) and SE ( ES=0.24, 95%CI =0.01-0.47) were positively correlated with subsequent day MVPA (both P <0.05). However, no statistically significant associations were found with LPA ( ES=-0.04, 95%CI =-0.13 to 0.06; ES=-0.02, 95%CI =-0.15 to 0.11) or TPA( ES=0.09, 95%CI =-0.02 to 0.20; ES=0.02, 95%CI = -0.03 to 0.06)(all P >0.05). Subgroup analysis revealed that in the "≤6 years" subgroup, SD and SE were positively correlated with TPA ( ES=0.22, 95%CI =0.09-0.35) and MVPA ( ES=1.19, 95%CI =1.06-1.32), respectively; in the "6-12 years" subgroup, SD was positively correlated with MVPA ( ES=0.05, 95%CI =0.02-0.08); in the "≥12 years" subgroup, SE was positively correlated with LPA ( ES=0.08, 95%CI =0.00-0.16), while SD was negatively correlated with LPA ( ES=-0.23, 95%CI = -0.31 to -0.16) (all P <0.05). Conclusion Adequate SD and good SE can effectively enhance subsequent day MVPA among children and adolescents, although these sleep effects vary by age group.

Objective To investigate the mediating role of anxiety and depression in social sup-port and burnout among primary caregivers of stroke patients.Methods A convenience sampling method was employed to select 506 primary caregivers of stroke patients as research subjects.The Gen-eral Information Questionnaire,Caregiver Burnout Inventory for Stroke Patients,Multidimensional Scale of Perceived Social Support,and Hospital Anxiety and Depression Scale were used for data col-lection.Results The total scores for caregiver burnout,social support,anxiety,and depression a-mong primarycaregivers of stroke patients were(72.83±14.32),(47.79±7.74),(10.49±3.00),and(10.45±3.06),respectively.Correlation analysis revealed a negative correlation between caregiver burnout and social support(r=-0.245,P＜0.001),and positive correlations with anxiety and depression(r=0.178,0.216,P＜0.001).Anxiety and depression partially media-ted the relationship between social support and caregiver burnout,accounting for 7.9％and 10.7％of the total effect,respectively.Conclusion Social support,anxiety,depression,and burnout are closely interrelated.Social support can directly or indirectly influence the occurrence of burnoutthrough anxiety and depression.Medical staff should pay attention to the anxiety and depression status of primary caregivers of stroke patients and enhance social support levels to reduce the incidence of burnout by alleviating anxiety and depression.

Objective To investigate the prevalence and influencing factors of work-related musculoskeletal disorders (WMSDs) among bus drivers. Methods A total of 962 drivers from a bus company in Shenzhen City were selected as the research subjects using the judgment sampling method. The Musculoskeletal Disorders Questionnaire for Bus Drivers was used to investigate the prevalence of WMSDs among the research subjects. Results The prevalence of WMSDs was 37.8% in the bus drivers. The prevalence of WMSDs was higher in the low back/waist, neck, and shoulder compared with other body parts, with prevalence of 24.0%, 20.2%, and 14.8%, respectively. The prevalence of single-site and multi-site WMSDs was 18.5% and 19.3%, respectively. The results of the multivariable logistic regression analysis showed that longer job tenure and higher alcohol consumption frequency were associated with higher WMSDs risks (all P<0.01). Weekly work time >48 hours, insufficient rest, work-related fatigue, uncomfortable auxiliary lenses, non-upright trunk posture, prolonged static trunk posture, prolonged wrist flexion, and habitual staying up late were risk factors of WMSDs in the bus drivers (all P<0.05). Conclusion The prevention and treatment of WMSDs among the bus drivers cannot be ignored. Personal characteristics, work organization, work environment, working posture and sleeping habits are the factors that influence the development of WMSDs.

Glucose-6-phosphate dehydrogenase(G6PD)deficiency is one of the most common monogenic genetic diseases in the world.China is the high incidence area of this disease.G6PD heterozygote is the main form of G6PD deficiency in females,which belongs to X-linked incomplete dominant inheritance.Therefore,the enzyme activities of female heterozygotes vary widely,showing normal to mild to moderate enzyme activi-ties.There is no unified calibrators for G6PD enzymatic detection reagents commonly used in clinical practice,and the results of the same sample detected by different kits from different manufacturers are different,so there is a phenomenon of missed detection in clinical screening of female G6PD heterozygotes.Although G6PD gene detection can effectively improve the detection rate of female heterozygotes,its clinical application is lim-ited due to cost and other reasons.Therefore,the development of detection methods that can improve the de-tection rate of female heterozygotes and are suitable for large-scale screening and clinical application will be an urgent need to be solved in clinical practice.This article reviews the epidemiology of G6PD deficiency,genetic characteristics of female G6PD gene,clinical manifestations and detection methods of G6PD female heterozy-gotes.

OBJECTIVE To analyze the direct economic burden associated with carbapenem-resistant gram-negative bacteria(CRGNB)infections during hospitalization,and to provide reference for relevant policy formulation.METHODS Basic information including ICU admission,International Classification of Diseases(ICD)codes and CRGNB infection of intensive care unit(ICU)inpatients from Sanya Central Hospital(the Third People's Hospi-tal of Hainan Province)in the southern Hainan region from 2019 to 2023 was collected for risk factor analysis.Propensity matching was performed between the CRGNB infection and non-infection subgroups,and the direct economic differences between the two groups were analyzed.RESULTS A total of 164 373 cases were includ-ed.Multifactor logistic regression analysis revealed that ICD codes F00-F99,G00-G99,I00-I99,J00-J99,L00-L99,N00-N99,P00-P96 and S00-T98,ICU admission,hospital-acquired infection,readmission within 90 days and hospitalization exceeding 7 days were risk factors for CRGNB infection,especially,codes J00-J99(respiratory system diseases)were 7.68 to 17.47 folds higer than codes C00-D48(tumors).In the direct economic analysis of CRGNB infection,different matching results yielded consistent findings.In the 1∶1 matching results,a compari-son of total hospitalization costs(yuan)between different groups showed that the infection group had higher total hospitalization costs than the non-infection group.The costs were as follows:CRGNB group(88 421.40 vs.32 475.56),subgroup with two or more CRGNB types(130 984.02 vs.47 367.27),group with CRGNB and oth-er multidrug-resistant bacteria(103 056.35 vs.37 724.78),CRAB group(98 486.01 vs.36 487.98),and CRE group(26 031.38 vs.17 621.82).CONCLUSIONS The direct economic burden of CRGNB infection is greater than that of the non-infection group.Among them,the direct economic burden of carbapenem-resistant gram-negative bacteria infection,carbapenem-resistant gram-negative bacteria co-infected with other multidrug-resistant bacteria and CRAB infection are the highest.

Objective:To explore the influencing factors of self-management of first-treatment pulmonary tuberculosis patients based on the random forest model, and to provide a theoretical basis for clinical staff to improve the self-management of pulmonary tuberculosis patients by providing efficient, high-quality, and individualized interventions.Methods:A cross-sectional study was used to select pulmonary tuberculosis patients who were hospitalized in the Department of Respiratory Medicine of the Fourth People′s Hospital of the Ningxia Hui Autonomous Region and who met the inclusion and exclusion criteria from December 2023 to February 2024 by using the convenience sampling method as the study subjects. General information questionnaire, Chronic Disease Patients′ Self-health Management Ability Assessment Scale, Perceived Social Support Scale, Hospital Anxiety and Depression Scale, and a tuberculosis prevention and treatment knowledge questionnaire were used to conduct the survey, and Spearman′s correlation was used to analyze the correlation between variables, and multivariate linear regression and a random forest model were used to analyze the influencing factors of self-management.Results:A total of 204 first-treatment pulmonary tuberculosis patients, 111 males and 93 females, 64 patients aged 18-44 years, 59 patients aged 45-59 years, and 81 patients ≥60 years were finally investigated. The total self-management score of tuberculosis patients was 162.00 (148.00, 176.75), and the total self-management score was positively correlated with the total perceived social support score, family support, friend support, and other support, respectively ( r values were 0.307-0.400, all P<0.01), negatively correlated with the anxiety and depression scores, respectively ( r=-0.195, -0.313, both P<0.01), and positively correlated with the total score of knowledge of tuberculosis control ( r=0.257, P<0.01); the results of multiple linear stepwise regression analysis showed that literacy, family support, other support, anxiety, and knowledge of tuberculosis control were the influencing factors of self-management ability ( t values were -2.89-2.98, all P<0.05), which explained a total of 23.1% of the total variance; and the random forest model ranked the importance of the influencing factors in the order of high to low were other support, family support, knowledge of tuberculosis control, literacy, and anxiety. Conclusions:The self-management of first-treatment pulmonary tuberculosis patients is at an intermediate level, In order to improve the self-management ability of first-treatment pulmonary tuberculosis patients, clinical personnel should establish a "patient-centered" self-management education concept, pay attention to the construction of their social support system, provide adequate, continuous, individualized knowledge education and information support, promote their psychological health, and reduce their negative emotions.

The clinical data of a patient with Klinefelter syndrome (KS) complicated by partial androgen insensitivity syndrome (PAIS) was retrospectively analyzed.The patient, a 2-month-and-22-day-old baby, was admitted to Children′s Hospital Affiliated to Zhengzhou University due to abnormal external genitalia in October 2021.Upon birth, the patient exhibited abnormal external genitalia, manifested as clitoral hypertrophy.Hormonal examinations were consistent with those of peers, while chromosomal analysis revealed 47, XXY.Due to the severe undermasculinization, whole exome sequencing was conducted, indicating a heterozygous variant of the AR gene (c.1847G>A, p.Arg616His). The patient was diagnosed with PAIS, and her elder sister was diagnosed with complete androgen insensitivity syndrome.For further treatment, a multidisciplinary comprehensive evaluation is needed.This is a rare case of KS combined with PAIS, suggesting the possibility of AR gene mutations in KS children with severe undermasculinization.

Objective:To analyze the status quo of type D personality, intolerance of uncertainty and family support in first-episode stroke patients, and to explore the mediating role of family support between type D personality and intolerance of uncertainty in first-episode stroke patients, in order to provide reference for formulating relevant clinical intervention measures to promote the physical and mental health of first-episode stroke patients.Methods:This study was a cross-sectional investigation. A total of 300 patients with acute first-episode stroke who met the inclusion and exclusion criteria in the Department of Neurology of the General Hospital of Ningxia Medical University and the First People′s Hospital of Yinchuan from May 2023 to September 2023 were selected as the study objects by convenience sampling method. The general data questionnaire, Type D personality Scale-14, Family Caring Index Scale and the Intolerance of Uncertainty Scale were used to investigate them. Pearson correlation analysis was used to test the correlation between variables, and SPSS plug-in PROCESS 3.5 was used to test the mediation effect.Results:Finally, 300 questionnaires were effectively collected, including 228 males and 72 females. Patients aged ≥ 60 years old were the majority, accounting for 49.3% (148/300). The detection rate of type D personality in the first stroke patients was 37.3% (112/300), and the total score of Type D personality inventory, family support and intolerance of uncertainty of type D personality in the first stroke patients were (22.16 ± 9.95), (6.40 ± 2.23), (27.82 ± 7.93) points. The correlation analysis results showed that the intolerance of uncertainty of type D personality in the first stroke patients was positively correlated with type D personality scores ( r=0.675, P<0.001). There was a negative correlation with family support score ( r=-0.644, P<0.001). The results of mediating effect analysis showed that family support played a partial mediating role in the relationship between type D personality and intolerability of uncertainty in first-stroke patients, and the mediating effect accounted for 34.94% of the total effect. Conclusions:The mediating role of family support between type D personality and intolerability of uncertainty in first-stroke patients is established. In the future, the level of family support of patients can be continuously improved to reduce their intolerability of uncertainty, so as to promote the physical and mental health of patients and improve their quality of life.
