Objective:To understand the current status of oral frailty in elderly diabetic patients and analyze its influencing factors.Methods:A convenience sampling method was used to select elderly diabetic patients hospitalized at Henan Cancer Hospital and Henan Provincial People's Hospital from October 2023 to May 2024. The general information questionnaire, Oral Frailty Index-8 (OFI-8) , Short Form of Health Literacy Dental Scale (HeLD-14) , Nutritional Risk Screening 2002 (NRS 2002) , and the Diabetes Distress Scale (DDS) were used to collect data. Binary Logistic regression analysis was used to examine the influencing factors of oral frailty in elderly diabetic patients.Results:A total of 235 questionnaires were distributed, and 220 valid questionnaires were returned, with an effective response rate of 93.62% (220/235) . The incidence of oral frailty in elderly diabetic patients was 46.82% (103/220) . The binary Logistic regression analysis showed that glycated hemoglobin, dry mouth, remaining teeth, nutritional risk, oral health literacy, and diabetes distress were significant influencing factors for the occurrence of oral frailty in elderly diabetic patients ( P<0.05) . Conclusions:The current status of oral frailty in elderly diabetic patients is concerning. Healthcare providers should pay attention to the oral health status of elderly diabetic patients and provide targeted nursing interventions and recommendations based on the influencing factors of oral frailty, in order to reduce its occurrence.

To investigate the clinical value of endoscopic ultrasound-guided puncture drainage in the treatment for liver abscess and abdominal and pelvic abscess with difficulty in conventional puncture drainage. Data of 12 such patients in the Second Affiliated Hospital of Soochow University from January 2015 to November 2023 were retrospectivly analyzed. Results showed liver abscess in 4 cases, abdominal and pelvic abscess in 8 cases. All patients had fever with varying degrees of abdominal pain. Twelve patients with liver abscess and abdominal and pelvic abscess received 13 times of endoscopic ultrasound-guided puncture (1 patient with a large abdominal and pelvic cyst complicated with infection received transgastric and transrectal puncture of 2 times). The puncture needle was successfully penetrated into the pus cavity. Four patients with liver abscess underwent endoscopic ultrasound-guided suction and irrigation, and the abscess was almost completely aspirated. Seven patients with abdominal and pelvic abscess underwent endoscopic ultrasound-guided suction and irrigation, of which 5 cases were almost completely aspirated, and 2 cases had poor drainage effect due to the viscous pus (1 case returned to normal temperature after anti-infection treatment; 1 case had recurrent fever after the operation, and septic shock and death occurred 2 weeks after the operation). A patient with recurrent abdominal and pelvic sclerosis after the operation had multiple abscesses in the abdomen and pelvis, and percutaneous CT-guided drainage was performed for abdominal abscess, but the fever was still repeated. Endoscopic ultrasound-guided balloon dilation plus double pig tail and nasobiliary duct drainage were performed. The patient's temperature returned to normal and abdominal pain was relieved 48 hours after the operation. The total effective rate of abscess drainage was 83.3% (10/12), and the effective rate of suction combined with irrigation for abscess drainage was 81.8% (9/11), and no operation-related complications were observed in all patients. After 3 months of follow-up, no recurrence occurred in 10 patients with effective drainage of abscess, and abscess was self-absorbed in 1 patient with pelvic abscess without effective drainage and no recurrence was observed. Endoscopic ultrasound-guided puncture drainage is of certain clinical value for some liver abscesses and abdominal and pelvic abscesses that are difficult to be drained by conventional puncture, and can reduce the secondary trauma caused by surgical operations.

BACKGROUND: Whether adherence to a healthy lifestyle is associated with a lower risk of developing pneumonia and a better long-term prognosis remains unclear. This study aimed to investigate associations of individual and combined lifestyle factors (LFs) with the incidence risk and long-term prognosis of pneumonia hospitalization. METHODS: Using data from the China Kadoorie Biobank study, we used the multistate models to investigate the role of five high-risk LFs, including smoking, excessive alcohol drinking, unhealthy dietary habits, physical inactivity, and unhealthy body shape, alone or in combination in the transitions from a generally healthy state at baseline to pneumonia hospitalization or cardiovascular disease (CVD, regarded as a reference outcome), and subsequently to mortality. RESULTS: Most of the five high-risk LFs were associated with increased risks of transitions from baseline to pneumonia and from pneumonia to death, but with different risk estimates. The greater the number of high-risk LFs, the higher the risk of developing pneumonia and long-term mortality risk after pneumonia, with the strength of associations comparable to that of LFs and CVD. Compared to participants with 0-1 high-risk LF, the adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for transitions from baseline to pneumonia and from pneumonia to death in those with five high-risk LFs were 1.43 (1.28-1.60) and 1.98 (1.61-2.42), respectively. Correspondingly, the respective HRs (95% CIs) for transitions from baseline to CVD and from CVD to death were 2.00 (1.89-2.11) and 1.44 (1.30-1.59), respectively. The risk estimates changed slightly when further adjusting for the presence of major chronic diseases. CONCLUSION In this Chinese population, unhealthy LFs were associated with an increased incidence and long-term mortality risk of pneumonia.

Peripheral vascular intervention involves multi-site and complex vascular lesions.The construction of a realistic model and the implementation of surgical simulation with the help of simulation medical technology can be applied to the training of interventional physicians and the optimization of individualized treatment strategies for patients.In order to adapt to the simulation scenarios of different blood vessels and achieve the required simulation effects,there have already been many reports concerning the construction of peripheral vascular models and clinical applications,such as the construction of animal models and cadaver models,the application of virtual reality simulators,the construction of different types of 3D printing vascular models,etc.This paper aims to make a detailed review about the methods of constructing these models and the research progress in the individualized diagnosis and treatment of patients.

Objective To analyze the incidence,colonization pathways,and predictive factors of bacterial colonization of epidural analgesia catheters in patients with chronic pain.Methods A total of 150 patients with chronic pain who underwent continuous epidural catheterization(catheter in-dwelling time of 7 to 10 days)were selected as study subjects.Samples from three sites were collect-ed for bacterial culture.Clinical data of the patients were collected,and the positive rate of bacterial culture,characteristics of bacterial species distribution,and bacterial colonization pathways were ana-lyzed.The efficacy of predictive factors was assessed using the receiver operating characteristic(ROC)curve.Results The positive rates of bacterial culture in samples from the skin swabbing fluid around the puncture site,the subcutaneous segment of the catheter,and the catheter tip were 22.0％,7.3％,and 8.7％,respectively.Staphylococcus epidermidis was the predominant colonizing bacterial species.Spearman correlation coefficient analysis showed a significant correlation between the results of bacterial culture from the skin around the puncture site and catheter tip colonization(r=0.47,P＜0.01).ROC curve analysis revealed that the area under the curve of bacterial culture results from the skin around the puncture site in predicting catheter tip bacterial colonization was 0.843,with a sensitivity of 84.9％and a specificity of 84.6％.Conclusion Bacterial migra-tion along the catheter is the main pathway for catheter tip bacterial colonization,and the results of bacterial culture from the skin around the puncture site are an effective predictive factor for the risk of bacterial colonization.

The ability of cells to sense and adapt to metabolic changes and environmental variations is essential for their functions. Recent advances in synthetic biology have uncovered increasing mechanisms through which cells detect changes in metabolism and environmental conditions, leading to broader applications. However, a systematic review on the regulation of cellular metabolism and environmental adaption is currently lacking. This article presents a comprehensive overview of this field from three perspectives. First, it introduces key transmembrane and sensor proteins involved in the cellular perception of metabolic and environmental changes. Next, it summarizes the adaptive regulation mechanisms that natural cells employ when confronted with intracellular and extracellular metabolic changes. Finally, the review explores the application scenarios based on cellular adaptive regulation in three aspects: dynamic control, rational metabolic engineering, and adaptive evolution and makes an outlook on the future development directions in this field. This review not only provides a comprehensive perspective on the mechanisms by which cells sense metabolic and environmental variations, but also lays a theoretical foundation for further innovations in the field of synthetic biology. With the continuous advancement of future technologies, a deeper understanding of cellular adaptive regulation mechanisms holds great potential to drive the development and application of novel biomanufacturing platforms.

Objective To explore the impact of ondansetron's use within 24 h before delirium assess-ment in ICU patients on the risk of delirium occurrence.Methods All data were derived from the Critical Care Medical Information Database(MIMIC)-Ⅲ,MIMIC-Ⅳ and the eICU Collaborative Research Database.The research subjects were the patients who were admitted to ICU for treatment for the first time and had re-cords of delirium assessment.The research variable was whether ondansetron was used within 24 h before de-lirium assessment.The main observation indicator was whether delirium occurred after the patient entering to ICU,and whether the patient died during hospitalization or was discharged and returned home was taken as the secondary observation indicator.The propensity score matching eliminated confounding factors,and the stepwise logistic regression and nearest neighbor matching were used to analyze the influencing factors.Results A total of 78 364 patients had the delirium assessment records,among them 22 158 patients had the positive assessment results.A total of 294 patients who used ondansetron within 24 h before delirium assess-ment were taken as the ondansetron group,and 78 070 patients who did not use ondansetron were taken as the control group.Propensity score matching corrected most of the covariates between the two groups.The results of multivariate logistic regression analysis showed that the use of ondansetron was a protective factor for the delirium occurrence(OR=0.72,95％CI:0.53-0.96),and the results of nearest neighbor matching analysis also supported this association(OR=0.48,95％CI:0.31-0.76).However,the use of ondansetron had no effect on the outcome of in-hospital death or discharge home for critically ill patients(P＞0.05).Conclusion Ondansetron may be an effective drug for the prevention or treatment of delirium in critically ill patients.

Postoperative infection of internal fixation of closed fractures the lower limbs in adults represents a devastating complication, characterized by diagnostic challenges, prolonged treatment duration and high disability rates. Current management of these infections faces multiple challenges, such as difficulties in early accurate diagnosis, and various controversies about the treatment plan, leading to poor overall diagnosis and treatment results. To address these issues, based on evidence-based medicine and principles with emphasis on scientific rigor, clinical applicability and innovation, the Trauma Branch of the Chinese Medical Association, Orthopedic Branch of the Chinese Medical Doctor Association, Orthopedics Branch of the Chinese Medical Association, and Trauma Orthopedics and Polytrauma Group of the Resuscitation and Emergency Committee of the Chinese Medical Doctor Association have collaboratively organized a panel of relevant experts to develop the Guideline for diagnosis and treatment of infection after internal fixation of closed lower limb fractures in adults ( version 2025). The guideline proposed 10 recommendations, aiming to provide a foundation for standardized diagnosis and treatment of postoperative infection in adults with closed lower limb fractures.
