Background Frailty serves as a significant precursor to falls, disability, and mortality. Epidemiological evidence examining the impact of working hours on frailty remains scarce. Objective To explore the prevalence of frailty and the relationship between frailty and working hours among full-time middle-aged and older workers in China. Methods Data were derived from the 2020 China Health and Retirement Longitudinal Study (CHARLS). The study included full-time workers aged 45 years and above with a weekly working duration exceeding 35 h. Frailty was assessed using the Frailty Index (FI). First, the dose-response relationship between working hours and FI was explored using a generalized additive model (GAM). Second, univariate analyses were performed using t-tests, χ² tests, and the Jonckheere–Terpstra trend test. Restricted cubic splines (RCS) were introduced for modeling. Based on ordinal logistic regression models, covariates were adjusted sequentially to examine whether differences in frailty prevalence existed across different weekly working hour categories. Finally, subgroup analyses were performed. Results Among the 5504 included participants, the mean age was (56.41±7.30) years, with 2304 being female (41.86%). A total of 807 participants (14.66%) were identified as frail, and 2 686 participants (48.80%) were pre-frail. After standardization for gender and age according to the seventh national census data, the standardized prevalence of frailty and prefrailty were 18.89% and 47.25%, respectively. Significant higher proportions of frail individuals were found among those in non-managerial (73.73%), agricultural (64.06%), and non-employed (65.68%) occupations. Long working hours were prevalent: 2596 (47.17%) workers worked 41–60 h per week, 1649 (29.96%) worked >60 h per week, and only 1259 (22.87%) worked 35–40 h per week. GAM analysis showed a non-linear relationship between weekly working hours and FI. Restricted cubic spline analysis showed a statistically significant association between weekly working hours and frailty status (P=0.022). Logistic regression analysis revealed that individuals working more than 60 h per week had a 23% higher odds of frailty compared to those working 41–60 h (OR=1.23, 95%CI: 1.09, 1.38, P<0.01), while those working 35–40 h per week showed a 15% higher odds of frailty (OR=1.15, 95%CI: 1.01, 1.31, P=0.034). The subgroup analysis revealed that the positive association between working more than 60 h per week and frailty remained generally consistent across sex, age, urban/rural residence, occupational attributes, industry, or employment type, although the association did not reach statistical significance among non-rural residents and individuals aged 60 years and older. Conclusion The prevalence of frailty among full-time middle-aged and older labor force in China is relatively high, and the odds of frailty increases significantly among those who work more than 60 h per week. It is recommended to implement frailty prevention and management strategies targeting long-working-hour workers and to prioritize the impact of working duration on frailty.

Objective:To explore the correlation between skeletal muscle mass and strength with metabolic syndrome in children.Methods:This cross-sectional study was conducted involving 383 children aged 10 to 15 years who visited the Department of Child Health Care, Children′s Hospital of Nanjing Medical University from June 2021 to December 2022. Their height, weight, waist circumference, body composition, grip strength and blood pressure were measured. Relative skeletal muscle mass, muscle-to-fat ratio, and grip strength-to-body weight index were calculated. The levels of fasting blood glucose, lipids and insulin were tested. Homeostasis model assessment of insulin resistance (HOMA-IR) was calculated. Children were divided into the metabolic syndrome group and the non-metabolic syndrome group. Independent t test or Mann-Whitney U test etc. was used to compare the difference between groups. Spearman correlation analysis and binary Logistic regression were used to investigate the correlation between skeletal muscle mass and strength and metabolic syndrome. The area under the curve (AUC) of receiver operating characteristic (ROC) curve was used to compare the accuracy of the index of skeletal muscle in predicting metabolic syndrome in children. Results:Among the 383 children, 282 (73.6%) were male, at the age of 11.4 (10.6, 12.5) years. There were 216 children (56.4%) diagnosed with obesity and 90 children (23.5%) diagnosed with metabolic syndrome. Relative skeletal muscle mass, muscle-to-fat ratio, and grip strength-to-body weight index of the metabolic syndrome group were all lower than those in the non-metabolic syndrome group (all P<0.001). After adjusting for sex and age, relative skeletal muscle mass, muscle-to-fat ratio, and grip strength-to-body weight index were all negatively correlated with body mass index ( r=-0.84, -0.38, -0.63), waist circumference ( r=-0.76, -0.36, -0.70), systolic blood pressure ( r=-0.42, -0.21, -0.38), diastolic blood pressure ( r=-0.33, -0.18, -0.24), triglycerides ( r=-0.29, -0.13, -0.23), fasting insulin ( r=-0.28, -0.20, -0.29), and HOMA-IR ( r=-0.26, -0.18, -0.26) (all P<0.05), and positively correlated with high-density lipoprotein cholesterol ( r=0.38, 0.13, 0.31, all P<0.01). After adjusting for sex and age, high relative skeletal muscle mass, high muscle-to-fat ratio, and high grip strength-to-body weight index all decreased the risks of metabolic syndrome ( OR=0.80, 0.55, 0.90), obesity ( OR=0.53, 0.64, 0.82), hypertension ( OR=0.86, 0.58, 0.92), low high-density lipoprotein cholesterol ( OR=0.83, 0.62, 0.92), hypertriglyceridemia ( OR=0.88, 0.78, 0.96). After adjusting for sex and age, high relative skeletal muscle mass and high grip strength-to-body weight index all decreased the risks of hyperglycemia ( OR=0.93 and 0.95, all P<0.05). ROC curve analysis showed that the relative skeletal muscle mass, muscle-to-fat ratio, and grip strength-to-body weight index all had good predictive accuracy of metabolic syndrome in children (AUC=0.79, 0.71, 0.76), with optimal cutoff values of 40%, 1.2, and 35%, respectively. Conclusions:High relative skeletal muscle mass, high muscle-to-fat ratio, and high grip strength-to-body weight index are all protective factors for metabolic syndrome in children. Regular measurement of skeletal muscle mass and grip strength can aid in the early identification and prevention of obesity and metabolic syndrome during childhood .

Objective:To explore the clinical symptoms, imaging characteristics, cerebrospinal fluid (CSF) features, as well as the treatment and prognosis of autoimmune glial fibrillary acidic protein (GFAP) astrocytopathy.Methods:Sixty-one patients with anti-GFAP astrocyte antibody (GFAP-IgG) single-positive autoimmune encephalitis who were treated at the Third Affiliated Hospital, Sun Yat-sen University between January 2017 and September 2023 were retrospectively collected. The demographic characteristics (age at onset, sex), clinical symptoms (core symptoms, neurological deficits, psychiatric behavioral abnormalities, and autonomic dysfunction), imaging features [brain/spinal cord/optic nerve magnetic resonance imaging (MRI) lesion distribution and enhancement patterns], and CSF parameters were analyzed. Acute-phase treatments, including methylprednisolone pulse therapy, intravenous immunoglobulin (IVIG), etc, along with the follow-up outcomes [modified Rankin Scale (mRS) score] were recorded.Results:The onset age was 40 (30, 55) years, and 68.9% (42/61) of the patients were male. The most common clinical manifestations were fever (65.6%, 40/61), headache (60.7%, 37/61), and urinary/defecatory abnormalities (45.9%, 28/61). Brain MRI revealed lesions predominantly in the cerebral cortex and subcortical white matter (57.4%, 35/61), periventricular white matter (50.8%, 31/61), and basal ganglia (36.1%, 22/61). Periventricular linear-radiating enhancement was the predominant MRI enhancement pattern (55.7%, 34/61). Spinal MRI showed lesions mainly in the cervical (42.6%, 26/61) and thoracic spinal cord (32.8%, 30/61), with leptomeningeal enhancement (31.1%, 19/61) and scattered punctate/patchy enhancements (21.3%, 13/61). Optic neuropathy was observed in 6 cases (9.8%). CSF analysis demonstrated a pressure of 180 (133, 240) mmH 2O (1 mmH 2O=0.009 8 kPa), white blood cell count of 29 (4, 156)×10?/L, and protein level of 0.72 (0.40, 1.44) g/L. Nineteen patients (31.1%) experienced rapid progression of meningoencephalitis or myelitis within 3 days of admission. All patients received methylprednisolone pulse therapy, with 47.5% (29/61) additionally treated with IVIG. At a follow-up of 12 (3, 28) months, 12 cases (19.7%) relapsed, and 75.4% (46/61) had favorable outcomes (mRS score 0-2). Poor prognosis (mRS score>2) was observed in 4 cases, including 3 with cervical spinal cord involvement and status epilepticus, 1 elderly patient with lung cancer. Conclusions:GFAP astrocytopathy predominantly affects young adults, with a male predominance. Spinal cord involvement is common, manifesting as myelitis and myelopathy. Rapid progression of meningoencephalitis or myelitis may occur early in the disease course. Periventricular linear-radiating enhancement on brain MRI is a key diagnostic clue. Leukocyte and protein levels in the cerebrospinal fluid are generally mildly to moderately elevated. Most patients respond well to corticosteroids and immunotherapy, with favorable outcomes. However, advanced age and cervical spinal cord involvement are associated with poor prognosis.

OBJECTIVE: To carry out pathological and genetic analyses on a fetus with intrauterine growth restriction and death during second trimester after induced abortion. METHODS: A fetus undergone induced abortion due to intrauterine growth restriction and death during second trimester at the the Seventh Affiliated Hospital of Sun Yat-Sen University in 2024 was selected as the study subject. Clinical data of the pregnancy were collected. DNA was extracted from tissues from the aborted fetus and peripheral blood samples from its parents. Chromosomal microarray analysis and whole exome sequencing were carried out. Candidate variants were verified by Sanger sequencing. Following abortion, routine autopsy and pathological analysis were conducted. This study was approved by the Medical Ethics Committee of the hospital (Ethics No.: KY-2025-334-01). RESULTS: The aborted fetus was a male and harbored compound heterozygous nonsense variants of the TH gene (c.457C>T/p.Arg153* and c.694C>T/p.Gln232*), for which both parents were heterozygous carriers. Autopsy and pathological analysis revealed that the fetus had pathological features including loose arrangement of myocardial fibers and congestion in the liver. CONCLUSION Biallelic null variants of the TH gene may cause heart failure by affecting the development of cardiovascular system, which in turn may lead to intrauterine death. This study has provided new clues for the molecular diagnosis of stillbirth and recurrent pregnancy loss.

Dengue fever is a mosquito-borne disease prevalent in tropical and subtropical regions, with its prevalence expanding due to increased global travel. The dengue virus, the causative agent of dengue fever, often co-circulates in the form of four distinct serotypes. Cross-reactive antibodies generated during a primary infection pose a significant risk during secondary infections with different serotypes, and fully protective vaccines and antiviral drugs are yet to be developed. Over the past decade, advances in antibody technology have led to the isolation of numerous monoclonal antibodies against dengue virus, with their neutralizing epitopes elucidated through structure-based analyses. This review highlights the key epitopes associated with neutralizing antibodies against dengue virus and discusses their potential applications in vaccine design and therapeutic antibody development. This review helps systematically summarize the progress in dengue virus neutralizing antibody research, providing a theoretical foundation and technical guidance for the development of novel vaccines and antibody therapeutics.

Objective:To explore the trends and outcomes for heart transplantation (HT) in elderly recipients and further examine the related risk factors.Methods:Between June 2004 and December 2021, retrospective review was conducted for the relevant clinical data and age distribution of 1044 HT recipients aged ≥18 year at Fuwai Hospital. The study population was assigned into two groups of elder (≥60 year, n=877) and non-elder (<60 year, n=157). Subgroup analysis was made between recipients aged <65 year (n=107) and those aged ≥ 65 year (n=50) in elder group. Baseline demographic profiles, clinical data, in-hospital and one-year post-transplant mortality and long-term survival were compared between two groups. Then a further comparison of long-term survival was conducted among the groups of non-elder, elder aged <65 year and elder aged ≥65 year. Cox proportional risk regression and multivariate Logistic regression models were utilized for examining the relevant risk factors for cumulative survival rate and short-term mortality. Kaplan-Meier analysis was employed for plotting survival curves and Log-rank test for comparison. Multivariate Cox proportional risk regression model was utilized for examining the relevant risk factors for cumulative survival rate and multivariate Logistic regression model for analyzing the relevant risk factors for short-term mortality. After adjusting for other confounding factors, the impact of recipient age on survival post-HT was determined.Results:The number of elderly HT recipients spiked annually at our center while average age of adult recipients and average age of elderly recipients have remained relatively constant. The median follow-up period was 6.5 years. Regarding baseline data, statistically significant differences existed in ratio of males [84.7%(113/157) vs 77.5%(687/877)], hypertension history [20.4%(32/157) vs 8.9%(79/877)], smoking history [47.1%(74/157) vs 36.1%(320/877)], diabetic history [33.8%(53/157) vs 14.7%(130/877)], preoperative ICD/CRT/CRT-D implantation [28.0%(44/157) vs 18.0%(160/877)], value of creatinine [(105.3±25.3) vs (96.8±35.0) μmol/L], IMPACT score [(6.9±2.4) vs (4.2±2.9) point], serum total bilirubin [19.7(13.6, 30.3) vs 23.7(15.8, 36.8) μmol/L], mean pulmonary arterial pressure [(26.0±10.3) vs (29.7±11.0) mmHg (1 mmHg=0.133 kPa)] and ischemic duration [(274.7±105.6) vs (296.0±120.4) min] (all P<0.05). No significant inter-group difference existed in in-hospital mortality [4.5%(7/157) vs 4.7%(42/887)] or 1-year mortality [5.7%(9/157) vs 6.5%(58/887)] ( P=0.88, P=0.70); in-hospital mortality and 1-year postoperative mortality of recipients aged ≥65 years 10.0%(5/50) and 14.0%(7/50) were both higher than those aged <65 year [1.9%(2/107), 1.9%(2/107)]. The differences were both statistically significant ( P=0.02, P<0.01). Kaplan-Meier survival analysis indicated that long-term survival rate was lower in elder group than that in non-elder group and the difference was statistically significant ( P=0.046). Long-term survival rate of elders aged ≥65 year was lower than that of non-elders aged <65 year and the difference was statistically significant ( P<0.01). Regression analysis indicated that age of recipient ≥65 year, preoperative creatinine ≥133 μmol/L, preoperative total bilirubin ≥25.65 μmol/L and preoperative support of extracorporeal membrane oxygenation (ECMO) were independent risk factors for short/long-term mortality post-HT. Conclusion:Although long-term prognosis of elderly recipients is slightly worse than that of non-elderly ones, in-hospital mortality and one-year postoperative mortality are similar between two groups. For elderly recipients with fewer comorbidities and better preoperative status, they should not be excluded from HT based solely upon age. The long-term prognosis of recipients aged ≥65 year remains poor and HT decisions should be made carefully.
