Objective To study the effect of incorporating comprehensive geriatric assessment(CGA)into the whole-process WeChat-based case health management in elderly population who took annual physical examinations,thereby to improve their ability in health self-management.Methods A randomised controlled trial was conducted to select 100 elderly people who took annual physical examinations in our hospital from July 2022 to June 2023.The elderly were randomly divided into a control group and an trial group,with 50 people per group.CGA was applied to both groups,but the control group was under conventional health management,while the trial group received the incorporation of CGA into a whole-process WeChat-based case health management.The self-rated abilities for health practices scale(SRAHP)was used to compare the scores between the two groups before intervention,at 3,6 and 12 months after intervention.The scores of fatigue,resistance,ambulation,illnesses&loss of weight scale(FRAIL)and the mini nutritional assessment-short form(MNA-SF)were compared between the two groups before intervention and at 12 months after intervention.Incidence of falls was also evaluated after intervention.Results All the participants completed the study.Repeated measures analysis of variance showed that total SRAHP scores had statistical significances in main effect on time,group and interaction(Ftime=193.451,P<0.001;Fgroup=23.661,P<0.001;Finteraction=29.970,P<0.001).Further analysis revealed that the elderly in trial group had higher total scores in SRAHP than those in the control group at 6 and 12 months after intervention(both P<0.001).At 12 months after intervention,the trial group showed better scores in FRAIL and MNA-SF than the control group(both P<0.05)as well as with a lower incidence of falls(P<0.05).Conclusion Incorporation of CGA into a comprehensive WeChat-based case health management,over a long-term,can effectively enhance the ability in health self-management among elderly individuals who take annual health examinations,improve frailty and nutritional status and reduce the incidence of falls.The health self-management discovered from this study provides a valuable reference for health management among the elderly people who take annual physical examinations.

Nonobstructive azoospermia (NOA), one of the most severe types of male infertility, etiology often remains unclear in most cases. Therefore, this study aimed to detect four biallelic detrimental variants (0.5%) in the minichromosome maintenance domain containing 2 ( MCMDC2 ) genes in 768 NOA patients by whole-exome sequencing (WES). Hematoxylin and eosin (H&E) demonstrated that MCMDC2 deleterious variants caused meiotic arrest in three patients (c.1360G>T, c.1956G>T, and c.685C>T) and hypospermatogenesis in one patient (c.94G>T), as further confirmed through immunofluorescence (IF) staining. The single-cell RNA sequencing data indicated that MCMDC2 was substantially expressed during spermatogenesis. The variants were confirmed as deleterious and responsible for patient infertility through bioinformatics and in vitro experimental analyses. The results revealed four MCMDC2 variants related to NOA, which contributes to the current perception of the function of MCMDC2 in male fertility and presents new perspectives on the genetic etiology of NOA.

Objective:To analyze the latent profile characteristics of self-management ability in patients with metabolic-associated fatty liver disease (MAFLD) and explore its influencing factors.Methods:This was a cross-sectional study. A total of 311 patients with metabolic-associated fatty liver disease (MAFLD) were selected from the First Affiliated Hospital of Sun Yat-sen University (including those receiving treatment and undergoing physical examinations) between August and October 2024. Data were collected using a general information questionnaire, the self-management Scale for Patients with Non-Alcoholic Fatty Liver Disease, and the Social Support Rating Scale. After excluding 51 patients due to incomplete questionnaire responses or logical inconsistencies, 260 patients were finally included in the analysis. Latent profile analysis was used to identify potential categories of patients′ self-management abilities. With the latent categories as the dependent variable and items with P<0.05 in univariate analysis as independent variables, a multivariate logistic regression analysis (with the "poor self-management group" as the reference group) was performed to explore the influencing factors. Results:Among the 260 participants included in the study, three potential categories of self-management behaviors were finally identified, namely the active self-management group with 106 cases (40.8%), the moderate self-management group with 118 cases (45.4%), and the passive self-management group with 36 cases (13.8%).Results of multivariate logistic regression analysis showed that, compared with the passive self-management group:Patients who resided in rural areas ( OR=0.130, 95% CI: 0.040-0.420), often stayed up late ( OR=0.200, 95% CI: 0.060-0.590), or had an average daily sleep duration of≤5 hours ( OR=0.160, 95% CI: 0.050-0.510) had a significantly lower probability of belonging to the "active self-management group";In contrast, patients with an education level of senior high school or above ( OR=7.530, 95% CI: 1.740-34.160) or a higher total score of social support ( OR=1.120, 95% CI: 1.030-1.210) had a significantly higher probability of being in the "active self-management group" (all P<0.05). Conclusion:There is heterogeneity in self-management ability among patients with metabolic associated fatty liver disease (MAFLD). Residential area, educational level, frequency of staying up late, average daily sleep duration, and social support are influencing factors of patients′ self-management ability.

Objective To explore the effect of stratified out-of-hospital health management led by case health manager on the health behaviour ability of the patients with chronic diseases.Methods A convenience sampling method was employed to select 481 patients with chronic diseases who underwent physical examinations at outpatient department of a Tier-IIIA hospital from April 2022 to April 2023.A health management team led by case health managers conducted questionnaire survey to investigate the individual characteristics of the patients,established personal record based on the physical examination,and implemented stratified out-of-hospital health management for the patients.The intervention lasted for 12 months.The health behaviour ability and chronic disease self-management efficacy of the patients before and after the intervention were compared with.Results After the case manager-led stratified out-of-hospital health management,the health behaviour ability of patients with chronic diseases was stronger than that before the implementation,the self-management efficacy of chronic diseases was better than that before the implementation,and the patients'satisfaction was higher than that before the implementation(all P<0.001).Conclusion Stratified out-of-hospital health management led by a case health manager can improve the health behaviour ability and self-management efficacy of the patient with chronic diseases,thereby improve the patients'satisfaction.

Objective:To assess the effectiveness of a 6-month Ba Duan Jin exercise program in improving the balance of community-dwelling older adults.Methods:A two arms, parallel-group, cluster randomized controlled trial was conducted in 1 028 community residents aged 60-80 years in 40 communities in 5 provinces of China. Participants in the intervention group (20 communities, 523 people) received Ba Duan Jin exercise 5 days/week, 1 hour/day for 6 months, and three times of falls prevention health education, and the control group (20 communities, 505 people) received falls prevention health education same as the intervention group. The Berg balance scale (BBS) score was the leading outcome indicator, and the secondary outcome indicators included the length of time of standing on one foot (with eyes open and closed), standing in a tandem stance (with eyes open and closed), the closed circle test, and the timed up to test.Results:A total of 1 028 participants were included in the final analysis, including 731 women (71.11%) and 297 men (28.89%), and the age was (69.87±5.67) years. After the 3-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 3.05 (95% CI: 2.23-3.88) points ( P<0.001). After the 6-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 4.70 (95% CI: 4.03-5.37) points ( P<0.001). Ba Duan Jin showed significant improvement ( P<0.05) in all secondary outcomes after 6 months of exercise in the intervention group compared with the control group. Conclusions:This study showed that Ba Duan Jin exercise can improve balance in community-dwelling older adults aged 60-80. The longer the exercise time, the better the improvement.

Chronic hepatitis B(CHB)is an infectious disease caused by persistent infection with the hepatitis B virus(HBV)and is highly prevalent worldwide.Non-alcoholic fatty liver disease(NAFLD)is a group of liver diseases related to metabolic abnormalities,excluding those caused by alcohol consumption or other liver injury factors.In recent years,with improvement of living standards and changes in lifestyle,the incidence of NAFLD has been increasing substantially,becoming the most common type of liver diseases in China and Western countries,and the second leading cause of liver transplantation in the West.The rising prevalence of NAFLD has also led to an increase in the incidence of NAFLD in patients with chronic HBV infection.However,there is considerable controversy both domestically and internationally regarding the relationship between these two diseases,including the disease progression,pathogenesis,impact on antiviral treatment efficacy,and prognosis of these concomitant CHB and NAFLD patients.Currently,both domestic and international guidelines lack detailed descriptions of diagnostic and treatment strategies for these conditions.This article summarizes the recent research progress in concomitant CHB and NAFLD,including epidemiology,diagnostic criteria,the impact of NAFLD on the virology of HBV infection,potential mechanisms of NAFLD-induced negative regulation of HBV,the effect of NAFLD on antiviral therapy effiicacy,and prognosis.This article aims to gain a deeper understanding of the diseases themselves and provide new insights for basic and clinical research as well as diagnostic and treatment approaches.
