Objective To explore the association between long working hours, anxiety symptoms, and insomnia symptoms among footwear industry workers, and to examine the mediating effect of anxiety symptoms between long working hours and insomnia symptoms. Methods A total of 710 workers from 15 footwear manufacturing enterprises in Guangdong Province were selected as study subjects using a stratified random sampling method. Long working hours, anxiety symptoms, and insomnia symptoms among the workers were assessed using the National Key Population Occupational Health Literacy Monitoring Questionnaire, the Chinese version of the Generalized Anxiety Disorder Self-Rating Scale, and the Self-Rating Sleep Questionnaire. Binary logistic regression was applied to analyze the associations of long working hours and anxiety symptoms with insomnia symptoms, and a mediation effect model was used to examine the mediating role of anxiety symptoms. Results The workers with long working hours accounted for 69.6% of participants. The detection rates of anxiety symptoms and insomnia symptoms were 17.0% and 20.7% in these workers, respectively. Binary logistic regression analysis showed that both long working hours and anxiety symptoms were influencing factors for insomnia symptoms (both P<0.01). Mediation analysis indicated that long working hours had a direct effect on insomnia symptoms, accounting for 67.9% of the total effect. Anxietysymptoms played a partial mediating role between long working hours and insomnia symptoms, with an effect value of 0.18 (95% confidence interval 0.07-0.30, P<0.01), accounting for 32.1% of the total effect. Conclusion Both long working hours and anxiety symptoms are influencing factors for insomnia symptoms among the footwear industry workers, and anxiety symptoms partially mediate the impact of long working hours on insomnia symptoms.

The disturbance of the human microbiota influences the occurrence and progression of many diseases. Live therapeutic bacteria, with their genetic manipulability, anaerobic tendencies, and immunomodulatory properties, are emerging as promising therapeutic agents. However, their clinical applications face challenges in maintaining activity and achieving precise spatiotemporal release, particularly in the harsh gastrointestinal environment. This review highlights the innovative bacterial functionalized encapsulation strategies developed through advances in physicochemical and biological techniques. We comprehensively review how bacterial encapsulation strategies can be used to provide physical barriers and enhanced adhesion properties to live microorganisms, while introducing superior material properties to live bacteria. In addition, this review outlines how bacterial surface coating can facilitate targeted delivery and precise spatiotemporal release of live bacteria. Furthermore, it elucidates their potential applications for treating different diseases, along with critical perspectives on challenges in clinical translation. This review comprehensively analyzes the connection between functionalized bacterial encapsulation and innovative biomedical applications, providing a theoretical reference for the development of next-generation bacterial therapies.

Background and purpose:Accurately locating pulmonary nodules is the key to the success of thoracoscopic surgery.This study aimed to investigate the strategy and evaluate the feasibility,safety,and clinical value of thoracoscopic surgical treatment for pulmonary nodules located beneath the interlobar pleura and close to the pulmonary hilum.Methods:The patients who underwent pulmonary nodule surgery at Liaocheng Tumor Hospital from May 2023 to November 2024 were enrolled,and the patients who did not meet the inclusion criteria were excluded.This study was approved by the Ethics Committee of Liaocheng Tumor Hospital(EC-20240112-1020)and informed consent was obtained from the patients.The research was designed as a prospective single-arm study.The patients were treated with wedge resection,which was performed following CT-guided localization,where the location needle was inserted through the interlobar pleura.The feasibility of the procedure was evaluated by analyzing the success rate of preoperative localization and perioperative complications.Results:A total of 28 patients who met the inclusion criteria were included in this study.There were 5 male and 23 female patients with an average age of(56.0±8.5)years(range 38-69 years).In all,28 patients with 28 nodules underwent thoracoscopic wedge resection,and the preoperative CT-guided localization was successfully performed in all patients,without urgent complications.The mean operation time of thoracoscopic surgery was(15.6±4.0)min,intraoperative bleeding was(20.9±14.3)mL,and postoperative drainage was(214.3±62.2)mL.No cases of postoperative air leaks or conversion to thoracotomy were observed.The average length of hospital stay was(5.4±0.9)days.The postoperative histological diagnosis revealed 3 benign lesions(pulmonary fibrosis in 2 cases,atypical adenomatous hyperplasia in 1 case)and 25 malignant lesions(adenocarcinoma in situ in 5 cases,minimally invasive adenocarcinoma in 16 cases,and invasive adenocarcinoma in 4 cases).Conclusion:Thoracoscopic wedge resection following CT-guided nodule localization through the interlobar pleura is a feasible approach for nodules located beneath the interlobar pleura and close to the pulmonary hilum.The method ensures precise tumor localization,adequate margin,and minimal loss of normal lung tissue,with a low incidence of postoperative complication,which has important guiding significance for the surgical treatment of pulmonary nodules in such special locations.

Objective To investigate the association between birth weight and dementia risk and the mediating roles of chronic diseases,and to assess potential biological pathways underlying the birth weight-associated dementia risk based on large-scale proteomics.Methods We used data from 279 743 participants aged 40 to 69 years enrolled in the UK Biobank.Birth weight was categorized into low birth weight(≤2 500 g),normal birth weight(2 500-3 999 g),and macrosomia(≥4 000 g).Multivariable Cox proportional hazards regression models were used to assess the associations between birth weight categories and all-cause dementia and its subtypes(Alzheimer's disease and vascular dementia).Proteomics analyses were conducted to identify proteins and the potential pathways involved.Results Low birth weight was associated with higher risks for all-cause dementia and its subtypes.The hazard ratios were 1.18(95%CI,1.08-1.30)for all-cause dementia,1.14(95%CI,1.00-1.31)for Alzheimer's disease,and 1.22(95%CI,1.01-1.48)for vascular dementia.A non-linear relationship was observed between birth weight and dementia risk(P for nonlinearity<0.001).Certain cardiometabolic diseases in middle-aged adults,such as diabetes,stroke,hypertension,and dyslipidemia,played a significant mediating role in the relationship between low birth weight and dementia risk,with the mediation proportion being 6.3%to 15.8%.Proteomic analyses identified 21 proteins linked to both low birth weight and all-cause dementia risk,which were significantly enriched in the pathways for viral protein interaction with cytokines and cytokine receptors,adipocytokine signaling,and cytokine-cytokine receptor interaction.Conclusion Low birth weight is positively associated with dementia risk.Cardiometabolic diseases in middle-aged adults may mediate the relationship between low birth weight and dementia risk.A number of proteins and the associated pathways underscore the relationship between low birth weight and dementia risk.

Objective:To identify the risk factors for acute lung injury (ALI) after pediatric living donor liver transplantation (LDLT) and evaluate the predictive value.Methods:The pediatric patients (all diagnosed with congenital biliary atresia) who underwent parental liver transplantation in our center from January to December 2021 were selected. Perioperative data were obtained through the electronic medical record system, and the pediatric patients were divided into non-ALI group and ALI group according to whether ALI occurred or not at 1 week after surgery. The factors of which P values were less than 0.05 between groups would enter the multivariate logistic regression analysis to stratify the risk factors for ALI after pediatric LDLT, and the value of the risk factors in predicting intraoperative ALI was evaluated using the receiver operating characteristic curve. Results:A total of 140 pediatric patients were enrolled in the analysis, and the incidence of ALI was 30.7%. The results of the multivariate logistic regression analysis showed that preoperative pediatric end-stage liver disease score, preoperative serum NT-pro-BNP concentrations, intraoperative volume of fluid transfused, and duration of postreperfusion syndrome were independent risk factors for ALI after LDLT in pediatric patients ( P<0.05). The area under the receiver operating characteristic curve of the preoperative N-terminal pro-brain natriuretic peptide(NT-pro-BNP) concentration in predicting postoperative ALI was 0.737 ( P<0.001), with a cutoff value of 222.1 ng/L, sensitivity of 0.628, and specificity of 0.732. Conclusions:Preoperative pediatric end-stage liver disease score, serum NT-pro-BNP concentrations, intraoperative volume of fluid transfused, and duration of postreperfusion syndrome are independent risk factors for ALI after LDLT in pediatric patients; preoperative serum NT-pro-BNP concentrations can effectively predict the development of ALI after pediatric LDLT surgery.

Objective:To evaluate the effect of stroke volume variation(SVV) goal-directed fluid therapy on postoperative pulmonary complications(PPCs) after pediatric living donor liver transplantation.Methods:One hundred and twenty pediatric patients undergoing pediatric living-donor liver transplantation(all diagnosed with congenital biliary atresia) were divided into 2 groups( n=60 each) using the random number table method: control group and SVV group. Intraoperative fluid management was guided by central venous pressure and mean arterial pressure in control group, while by SVV combined with cardiac output in SVV group. Intraoperative circulation, fluid intake and usage of vasoactive drug were recorded. Central venous blood samples were collected to determine the concentrations of serum Clara cell 16 kDa protein, interleukin-6, and tumor necrosis factor-alpha before anesthesia(T 0), at the end of anhepatic phase(T 1), at 3 h of neohepatic phase(T 2), at the end of surgery(T 3) and at 24 h after operation(T 4). Pulmonary ultrasonography was performed before surgery, at the end of surgery and at 1, 3 and 7 days after surgery. The pediatric patients were followed up for 1 week after surgery to record the PPCs, including acute lung injury, pulmonary infection, pulmonary atelectasis, pleural effusion and acute respiratory distress syndrome. Results:Compared with control group, the incidence of PPCs, acute lung injury and pulmonary infection was significantly decreased, the pulmonary ultrasound score was decreased at the end of surgery and at 1, 3 and 7 days after surgery, the usage of intraoperative dobutamine was increased, the duration of postreperfusion syndrome was shortened, the fluid intake and epinephrine usage were reduced, and the serum Clara cell 16 kDa protein, tumor necrosis factor-alpha and interleukin-6 concentrations were decreased at T 1-T 4 in SVV group( P<0.05). Conclusions:SVV goal-directed fluid management can reduce the development of PPCs in pediatric living donor liver transplantation.

Objective:To investigate the influencing factors of breakthrough cancer pain (BTcP) in patients with advanced pancreatic cancer.Methods:According to the inclusion and exclusion criteria, patients with advanced pancreatic cancer who were diagnosed and followed up by outpatient service in the 909th Hospital of the Joint Logistic Support Force from January 2019 to December 2020 were prospectively selected as the study subjects. According to whether breakthrough cancer pain occurred, all patients were divided into observation group (breakthrough cancer pain) and control group (no breakthrough cancer pain). The relevant clinical data of the included patients including age, gender, presence or absence of vomit, constipation, sleep disruption, frequency of basic pain every week, with or without regular medication, heavy physical labor, with or without vascular invasion, bone metastasis, abdominal metastasis and lung metastasis, as well as whether surgery, radiotherapy or chemotherapy were collected and the data of evaluation indicators during follow-up were recorded. Digital pain score (NRS) and visual analog score (VAS) were used as pain evaluation score. Univariate and logistic regression were used to analyze the related influencing factors of breakthrough cancer pain. Receiver operating characteristic curve (ROC) was drawn, and area under curve (AUC), sensitivity and specificity were calculated to analyze the predictive value for breakthrough cancer pain.Results:A total of 173 patients were included in the study, with 49 cases in the observation group and 124 cases in the control group. Univariate analysis showed that aged ≥50 years old, constipation, sleep disruption, frequency of basic pain ≥3 times, irregular medication, heavy physical labor, bone metastasis, lung metastasis, radiochemotherapy, high NRS score and high VAS score were the influencing factors for breakthrough cancer pain (all P value <0.05). Multivariate analysis showed that irregular medication ( OR=1.879, 95% CI 2.473-4.757, P=0.002), basal pain ≥3 times ( OR=2.067, 95% CI 1.364-6.825, P=0.004), bone metastasis ( OR=2.756, 95% CI 1.153-5.846, P<0.001), NRS score ( OR=3.787, 95% CI 2.647-5.958, P<0.001), VAS score ( OR=2.684, 95% CI 1.545-7.878, P<0.001), were the risk factors for breakthrough cancer pain. The AUC of NRS score for predicting the occurrence of breakthrough cancer pain was 0.665 (95% CI0.573-0.757, P=0.001), and the cut-off value was 2.5 score with a sensitivity of 61.2% and a specificity of 77.1%. The AUC for predicting breakthrough cancer pain by VAS score was 0.608 (95% CI0.515-0.701, P=0.028), and the cut-off value was 2.5 score with a sensitivity of 67.9% and a specificity of 63.7%. The AUC of NRS+ VAS score for predicting breakthrough cancer pain was 0.692 (95% CI0.604-0.780), and the cut-off value was 4.5 score with a sensitivity of 81.6% and a specificity of 79.8%. Conclusions:Patients with advanced pancreatic cancer have a high incidence of breakthrough cancer pain, which was related to a variety of factors. NRS combined with VAS score can effectively predict the occurrence of breakthrough cancer pain.

Objective:To explore the effect of intensive insulin therapy on hemodynamics and cardiac function in organ donors.Methods:A total of 60 organ donors were randomly divided into two groups of intensive insulin therapy(IIT)and control(30cases each group). Blood glucose was adjusted at 6.2~10.0 mmol/L in control group and 4.4~6.1 mmol/L in IIT group.Blood glucose and insulin dosage during maintenance were recorded.Cardiac function values as well as serum inflammatory factor concentrations at admission and during donation were compared between two groups.Results:During maintenance, blood glucose was significantly lower in IIT group than that in control group [(5.1±0.6)vs(8.2±1.5)mmol/L, P<0.05] and insulin dosage was higher than that in control group [(9.5±3.2)vs(5.8±1.5)U/h, P<0.05]. As compared with control group, cardiac cycle efficiency(CCE), maximal rate of elevated pressure(DP/DT max)and left ventricular ejection fraction(LVEF)in were significantly higher in IIT group than those of control group.And serum cardiac troponin I(cTnI), N-terminal B-type natriuretic peptide(NT-Pro-BNP), interleukin-6(IL-6), tumor necrosis factor-α(TNF-α)and high mobility group box-1 protein(HMGB1)as well as vasoactive-inotropic score(VIS)were significantly lower than those in control group( P<0.05). As compared with control group, cardiac donation rate of IIT group was significantly higher(30% vs 16.7%, P<0.05). Conclusions:Intensive insulin therapy and blood glucose control may blunt inflammatory response in organ donors, lessen myocardial injury and myocardial depression, stabilize hemodynamics and boost the rate of cardiac donation.
