Objective:s To investigate the risk factors for delayed encephalopathy after acute carbon monoxide poisoning (DEACMP) in patients with acute carbon monoxide poisoning (ACOP) and to develop predictive models based on machine learning algorithms.Methods:Patients with ACOP hospitalized at the First Affiliated Hospital of Zhengzhou University from August 2019 to October 2024 were included, with the occurrence of DEACMP as the outcome measure. The dataset was randomly divided into training and validation sets at a ratio of 7:3. Lasso regression was used to select features influencing the outcome in training sets. Nine machine learning models—including Random Forest (RF), Extreme Gradient Boosting (XGBoost), and Support Vector Machine (SVM)—were constructed. Receiver operating characteristic (ROC) curves were plotted and the area under the curve (AUC) calculated for each model. Calibration curves were used to assess accuracy, and decision curve analysis (DCA) was applied to evaluate clinical utility. The SHapley Additive exPlanations (SHAP) method was employed to visualize and interpret the best-performing model.Results:A total of 264 ACOP patients were included, of whom 54 (20.5%) developed DEACMP. Lasso regression identified eight key feature variables. Based on these factors, predictive models were constructed, showing good AUC stability across the nine machine learning models in both training (0.92–0.99) and validation sets (0.85–0.91). The RF model performed best, with an AUC of 0.99 in the training set and 0.90 in the validation set; its calibration curve and DCA curve also demonstrated excellent performance. SHAP analysis of the RF model revealed the importance ranking of factors from highest to lowest as follows: Glasgow Coma Scale (GCS) score, duration of coma, age, history of coronary heart disease, CK-MB level, monocyte count, diastolic blood pressure (DBP), and drinking history.Conclusions:The RF model exhibited the highest predictive performance for DEACMP occurrence in ACOP patients. The influencing factors, ranked in order of importance from highest to lowest, are as follows: GCS score, duration of coma, age, history of coronary heart disease, CK-MB level, monocyte count, DBP, and drinking history.

BACKGROUND: Epidemiological data on chronic diarrhea in the Chinese population are lacking, and the association between obesity and chronic diarrhea in East Asian populations remains inconclusive. This study aimed to investigate the prevalence of chronic diarrhea and its association with obesity in a representative community-dwelling Chinese population. METHODS: This cross-sectional study was based on a multistage, randomized cluster sampling involving 3503 residents aged 20-69 years from representative urban and rural communities in Beijing. Chronic diarrhea was assessed using the Bristol Stool Form Scale (BSFS), and obesity was determined based on body mass index (BMI). Logistic regression analysis and restricted cubic splines were used to evaluate the relationship between obesity and chronic diarrhea. RESULTS: The standardized prevalence of chronic diarrhea in the study population was 12.88%. The average BMI was 24.67 kg/m 2 . Of all the participants, 35.17% (1232/3503) of participants were classified as overweight and 16.13% (565/3503) as obese. After adjustment for potential confounders, individuals with obesity had an increased risk of chronic diarrhea as compared to normal weight individuals (odds ratio = 1.58, 95% confidence interval: 1.20-2.06). A nonlinear association between BMI and the risk of chronic diarrhea was observed in community residents of males and the overall participant group ( P  = 0.026 and 0.017, respectively). CONCLUSIONS This study presents initial findings on the prevalence of chronic diarrhea among residents of Chinese communities while offering substantiated evidence regarding the significant association between obesity and chronic diarrhea. These findings offer a novel perspective on gastrointestinal health management.

Objective:To systematically evaluate the application of patient-reported outcome measures (PROMs) in adult lung transplant recipients, and to explore their clinical value in assessing quality of life following transplantation.Methods:This study was a systematic review. Relevant studies published between January 2014 and July 2024 were searched in the PubMed and OVID Medline databases using keywords such as "lung transplantation" "quality of life" "HRQoL" "health indice" "patient-reported outcome measure" "questionnaire" "profile" "scale" "score" and "survey". Only English-language articles were included. Eligible studies were those that applied PROMs to assess quality of life in adult lung transplant recipients and were approved by ethics committees. Reviews, case reports, abstracts, and studies involving transplant candidates or recipients of lung-liver or lung-kidney combined transplantation were excluded. Data extracted included basic study information, study design, participant characteristics, and PROM usage. Frequently used PROMs and lung transplant-specific PROMs were summarized, and results with clearly reported time points were analyzed.Results:A total of 63 studies were included, comprising 54 (85.7%) observational studies and 9 (14.3%) interventional studies. The majority of studies originated from the United States (18 studies, 28.6%). A total of 55 different PROMs were identified, including 30 generic and 25 disease-specific instruments. The five most frequently used PROMs were the Short Form 36 (SF-36; 30 studies, 47.6%), the EuroQol 5 Dimension (EQ-5D; 12 studies, 19.0%), the St. George's Respiratory Questionnaire (SGRQ; 11 studies, 17.5%), the Hospital Anxiety and Depression Scale (HADS; 7 studies, 11.1%), and the modified Medical Research Council dyspnea scale (mMRC; 5 studies, 7.9%). Lung transplant-specific PROMs included the Lung Transplant Quality of Life questionnaire (LT-QOL), the Lung Transplant Valued Life Activities (LT-VLA) scale, and the Pulmonary-Specific Quality of Life Scale (PQLS), which were applied in only 6 studies (9.5%). Across studies, lung transplantation was associated with significant improvements in recipients' quality of life, sustained over a follow-up period of 3 to 60 months.Conclusions:A wide range of PROMs have been employed to assess health-related quality of life in lung transplant recipients; however, transplant-specific PROMs remain relatively scarce. PROMs provide valuable insights for reflecting and dynamically monitoring long-term quality of life, supplementing evidence for clinical decision-making, and optimizing post-transplant care strategies.

Pathological scar is a disease characterized by abnormal fibrous hyperplasia in the reticular layer of the dermis due to proliferation of fibroblasts, uncontrolled growth and excessive collagen deposition. Photodynamic chemotherapy, as a new treatment for pathological scar, has the advantages of being less invasive and having fewer adverse reactions. Its therapeutic principle consists of three basic elements: photosensitizers, photovoltaic illumination at a certain wavelength, and the generation of reactive oxygen species. This article primarily discusses the current application status and developmental prospects of photodynamic therapy in treating pathological scars, and also explores its limitations and challenges in scar management, aiming to provide references for laboratory research and clinical decision-making.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To explore the genetic background and clinical features of patients with long QT syndrome type 3 (LQT3).Methods:This retrospective cohort included patients diagnosed with LQT3 at the Department of Cardiology, Renmin Hospital of Wuhan University from January 1998 to December 2022. Patients were categorized into compound type group and single type group based on the presence of a single SCN5A mutation. The two groups were followed up and the differences in baseline characteristics, electrocardiograms, and clinical events between the two groups and probands were compared. Kaplan-Meier curves were used for survival analysis, and the log-rank test was employed to compare the event-free survival rates of first cardiac events between the groups and probands.Results:A total of 97 LQT3 patients were enrolled, including 59 probands. The age at diagnosis was (23.45±19.86) years, with 46 patients (47.4%) being male. Among them, 89 patients were classified as single type group, while 8 patients were classified as compound type group. Genetic testing identified 49 SCN5A mutations, with missense mutations being the majority (91.8%), primarily located in transmembrane regions (40.8%, n=20), interdomain linker regions (28.6%, n=14), and C-terminus (22.4%, n=11). The first cardiac event occurred in 44 patients (45.4%), with an onset age of (13.82±12.50) years. The main trigger was identified as rest or sleep (54.5%, n=24). Compared with patients in single type group, patients in compound type group were younger at diagnosis ((10.35±10.28) years vs. (24.63±20.13) years, P=0.040), had a significantly higher proportion of syncope (87.5% (7/8) vs. 33.7% (30/89), P=0.009), aborted cardiac arrest (62.5% (5/8) vs. 11.2% (10/89), P=0.001), and a lower incidence of event-free survival rates of first cardiac events (12.5% (1/8) vs.58.4% (52/89), log-rank P=0.001). The probands in compound type group had a significantly higher proportion of aborted cardiac arrest comparing to probands in single type group (62.5% (5/8) vs. 17.6% (9/51), P=0.020), while the difference in the incidence rate of event-free survival rates of first cardiac events between the probands in two groups was not statistically significant (12.5% (1/8) vs. 39.2% (20/51), log-rank P=0.08). Conclusion:Compound type LQT3 patients are not uncommon. Such patients are diagnosed at a younger age and exhibit more severe phenotypes, requiring close follow-up and proactive intervention strategies.
