Objective To investigate the risk factors for ICU-acquired weakness (ICU-AW) in patients with sepsis, and to construct a nomogram prediction model. Methods A total of 360 patients with sepsis admitted from January 2020 to December 2025 were enrolled as study subjects. The risk factors for ICU-AW were identified by logistic regression analysis. A nomogram prediction model was constructed, and the model was validated. Results Multivariate logistic regression analysis indicated that age, APACHE II score, duration of mechanical ventilation, duration of immobilization, duration of sedation, and NLR were risk factors for the occurrence of ICU-AW (P<0.05), while ALB was a protective factor (P<0.05). A nomogram model was constructed based on these seven variables. After validation via Bootstrap resampling, ROC curve showed an AUC of 0.949 (0.929–0.969) and a corrected AUC of 0.942 (0.940–0.948), indicating good discrimination degree of the model. Hosmer-Lemeshow test for calibration curve revealed a chi-square value of 10.188 (P=0.252), suggesting that the predicted value of fitting was generally consistent with the actual value. Decision curve analysis demonstrated that when the threshold was in the range of 0.05–0.9, the model had a good net benefit. Conclusion The nomogram prediction model for sepsis ICU-AW based on seven indicators including age, APACHE II score, NLR, ALB, and the durations of mechanical ventilation, immobilization, and sedation exhibits good predictive efficiency and stability. This nomogram prediction model is helpful for the clinical rapid screening of ICU-AW high-risk groups in patients with sepsis, and meets clinical needs for early warning and precise prevention and control.

ObjectiveTo investigate the knockdown efficiency of the liver-specific knockdown recombinant adeno-associated virus (AAV) thyroid-binding globulin (TBG) (AAV-TBG-shOTUD6B) targeting the ovarian tumor domain 6B (OTUD6B) of the ubiquitin-proteasome system in the liver of C57BL/6J mice and its regulatory effect on liver glucose metabolism. MethodsAn effective siOTUD6B sequence was designed and verified. The DNA sequences of non-specific interference RNA negative control (shNC) and shOTUD6B were inserted into the AAV vector backbone containing the promoter TBG to construct and purify AAV-TBG-shNC and AAV-TBG-shOTUD6B viruses. AAV-TBG-shNC and AAV-TBG-shOTUD6B were injected into mice via the tail vein to target the liver. After 8 weeks of high-fat diet (HFD) feeding, the levels of OTUDB protein and mRNA in the mice liver, as well as blood glucose levels, glucose tolerance, insulin sensitivity, and protein expression levels of phosphorylated protein kinase B (p-AKT) and phosphorylated glycogen synthase kinase-3β (p-GSK-3β) were detected. ResultsCompared with the AAV-TBG-shNC group, the OTUD6B protein level in the liver of the AAV-TBG-shOTUD6B group decreased, the mRNA level of OTUD6B in the liver decreased (P<0.01), the fasting blood glucose levels of the mice after 4 hours of fasting and 16 hours of fasting both decreased (P<0.05, P<0.01), the protein level of p-GSK-3β in the liver decreased (P<0.05), glucose tolerance was enhanced (P<0.05), insulin sensitivity was enhanced (P<0.01), and the protein level of p-AKT in the liver increased (P<0.05). ConclusionThe construction of a recombinant adeno-associated virus for liver OTUD6B knockdown is successfully completed. OTUD6B plays an important role in regulating the homeostasis of liver glucose metabolism. Liver-specific knockdown of OTUD6B can improve the blood glucose levels of mice induced by HFD and enhance insulin sensitivity.

Objective:
Previous studies have discovered a correlation between cigarette smoking and cortical thickness and surface area, but the causal relationship remains unclear. The objective of this investigation is to scrutinize the causal association between them.
Methods:
To derive summary statistics from a genome-wide association study (GWAS) on cortical thickness, surface area, and four smoking behaviors: 1) age of initiation of regular smoking (AgeSmk); 2) smoking initiation (SmkInit); 3) smoking cessation (SmkCes); 4) cigarettes per day (CigDay). Linkage disequilibrium score regression (LDSC) was employed to examine genetic association analysis. Furthermore, for traits with significant genetic associations, Mendelian randomization (MR) analyses were conducted.
Results:
The LDSC analysis revealed nominal genetic correlations between AgeSmk and right precentral surface area, left caudal anterior cingulate surface area, left cuneus surface area, left inferior parietal surface area, and right caudal anterior cingulate thickness, as well as between CigDay and left caudal middle frontal surface area, between SmkCes and left entorhinal thickness, and between SmkInit and left rostral anterior cingulate surface area, right rostral anterior cingulate thickness, and right superior frontal thickness (rg=-0.36–0.29, p<0.05). MR analysis showed a unidirectional causal association between left caudal middle frontal surface area and CigDay (βIVW=0.056, pBonferroni=2×10-4).
Conclusion
Left caudal middle frontal surface area has the potential to serve as a significant predictor of smoking behavior.

Objective To explore the recognition capabilities of electronic nose combined with machine learning in identifying the breath odor map of benign and malignant pulmonary nodules and Traditional Chinese Medicine (TCM) syndrome elements. Methods The study design was a single-center observational study. General data and four diagnostic information were collected from 108 patients with pulmonary nodules admitted to the Department of Cardiothoracic Surgery of Hospital of Chengdu University of TCM from April 2023 to March 2024. The patients' TCM disease location and nature distribution characteristics were analyzed using the syndrome differentiation method. The Cyranose 320 electronic nose was used to collect the odor profiles of oral exhalation, and five machine learning algorithms including random forest (RF), K-nearest neighbor (KNN), logistic regression (LR), support vector machine (SVM), and eXtreme gradient boosting (XGBoost) were employed to identify the exhaled breath profiles of benign and malignant pulmonary nodules and different TCM syndromes. Results (1) The common disease locations in pulmonary nodules were ranked in descending order as liver, lung, and kidney; the common disease natures were ranked in descending order as Yin deficiency, phlegm, dampness, Qi stagnation, and blood deficiency. (2) The electronic nose combined with the RF algorithm had the best efficacy in identifying the exhaled breath profiles of benign and malignant pulmonary nodules, with an AUC of 0.91, accuracy of 86.36%, specificity of 75.00%, and sensitivity of 92.85%. (3) The electronic nose combined with RF, LR, or XGBoost algorithms could effectively identify the different TCM disease locations and natures of pulmonary nodules, with classification accuracy, specificity, and sensitivity generally exceeding 80.00%.Conclusion Electronic nose combined with machine learning not only has the potential capabilities to differentiate the benign and malignant pulmonary nodules, but also provides new technologies and methods for the objective diagnosis of TCM syndromes in pulmonary nodules.

OBJECTIVE:
To describe survival trends and global patterns of esophageal cancer (EC) using survival data from population-based cancer registries.
METHODS:
We systematically searched PubMed, EMBASE, Web of Science, SEER, and SinoMed databases for articles published up to 31 December 2023. Eligible EC survival estimates were evaluated according to country or region, period, sex, age group, pathology, and disease stage.
RESULTS:
After 2010, Jordan exhibited the highest age-standardized 5-year relative survival rates (RSRs)/net survival rates (NSRs) at 41.1% between 2010 and 2014, while India had the lowest, at 4.1%. Survival rates generally improved with diagnostic age across most countries, with significant increases in South Korea and China, of 12.7% and 10.5% between 2000 and 2017, respectively. Survival was higher among women compared to men, ranging from 0.4%-10.9%. Survival rates for adenocarcinoma and squamous cell carcinoma were similar, differing by about 4%. In China, the highest age-standardized RSRs/NSRs was 33.4% between 2015 and 2017. Meanwhile, the lowest was 5.3%, in Qidong (Jiangsu province) between 1992-1996.
CONCLUSION
Global EC survival rates have improved significantly in recent decades, but substantial geographical, sex, and age disparities still exist. In Asia, squamous cell carcinoma demonstrated superior survival rates compared to adenocarcinoma, while the opposite trend was observed in Western countries. Future research should clarify the prognostic factors influencing EC survival and tailor prevention and screening strategies to the changing EC survival patterns.

BackgroundSevere mental disorders represent a major public health concern due to the high disability rates and substantial disease burden, which has garnered significant national attention and prompted their inclusion in public health project management systems. However, credible evidence regarding the current status of disease management and factors influencing disease stabilization among patients with severe mental disorders in Luzhou City, Sichuan Province, remains limited. ObjectiveTo investigate the current management status of patients with severe mental disorders in Luzhou City, Sichuan Province, and to analyze influencing factors of disease stabilization among patients under standardized care, so as to provide evidence-based insights for developing targeted management strategies to optimize clinical interventions for this patient population. MethodsIn March 2023, data were extracted from the Sichuan Mental Health Service Comprehensive Management Platform for patients with severe mental disorders in Luzhou City who received management between December 2017 and December 2022. Information on mental health service utilization and clinical status changes was collected. Trend analysis was conducted to evaluate temporal changes in key management indicators for severe mental disorders in Luzhou City. Logistic regression analysis was employed to identify factors influencing the disease stabilization or fluctuation of these patients. ResultsThis study enrolled a total of 20 232 patients. In Luzhou City, the stabilization rate and standardized management rate of severe mental disorders were 94.89% and 79.36% in 2017, respectively, which increased to 95.33% and 96.92% by 2022. The regular medication adherence rate rose from 34.42% in 2018 to 86.81% in 2022. In 2022, the regular medication adherence rate was 71.80% for schizophrenia, 55.26% for paranoid psychosis, and 51.43% for schizoaffective disorder. Multivariate analysis identified the following protective factors for disease stabilization: age of 18~39 years (OR=0.613, 95% CI: 0.409~0.918), age of 40~65 years (OR=0.615, 95% CI: 0.407~0.931), urban residence (OR=0.587, 95% CI: 0.478~0.720), and regular medication adherence (OR=0.826, 95% CI: 0.702~0.973). Risk factors for disease fluctuation included poor (OR=1.712, 95% CI: 1.436~2.040), non-inclusion in care-support programs (OR=1.928, 95% CI: 1.694~2.193), non-participation in community rehabilitation (OR=2.255, 95% CI: 1.930~2.634), and intermittent medication adherence (OR=3.893, 95% CI: 2.548~5.946). ConclusionThe stability rate, standardized management rate, and regular medication adherence rate of patients with severe mental disorders in Luzhou City have shown a year-by-year increase. Age, household registration status, economic condition, medication compliance, and community-based rehabilitation were identified as influencing factors for disease fluctuation in these patients.
