Objective: To examine the association between school sports environment and exercise habits among college students, and to test the mediating role of weight management intention in the relationship, so as to provide empirical evidence for promoting exercise habit formation of college students. Methods: A multi stage cluster sampling survey was conducted from April 15 to May 15, 2025, among 2 687 undergraduates from 8 colleges in Beijing, Shandong, Henan, Shanxi and Guangxi Zhuang Autonomous Region in China. School Sports Environment Characteristics Questionnaire, Weight Management Behavioral Intention Questionnaire and College Students Exercise Habit Scale were used for evaluation. Pearson correlation analysis was applied to examine the correlations among the three variables. A structural equation model (SEM) was constructed using AMOS 26.0, and the mediating effect was tested using the Bootstrap method. Results: The score for school sports environment was (3.72±0.57), with scores of (3.68±0.61) for physical environment and (3.74±0.59) for social environment; the scores for weight management intention and the total exercise habit were (4.21±0.46) and (3.94±0.51). School sports environment was positively correlated with weight management intention ( r =0.56) and exercise habits ( r =0.57), and weight management intention was positively correlated with exercise habits ( r =0.71) (all P <0.01). The SEM showed that school sports environment exerted positive impact on weight management intention ( β =0.50) and exercise habits ( β =0.29), weight management intention had a significant positive path to exercise habits ( β =0.52) (all P <0.01). Weight management intention of college students played a partial mediating role in the association between school sports environment and exercise habits, with an indirect effect of 0.259, accounting for 47.01% of the total effect. Conclusions The school sports environment is positively correlated with college students exercise habits, and might indirectly facilitate habit cultivation by improving weight management intention. While optimizing the physical and social environments of school sports in colleges, colleges should place a strong emphasis on stimulating college students weight management intention to promote the formation of their exercise habits.

OBJECTIVE: To assess the impact of albumin (Alb) administration on the prognosis of patients with acute kidney injury (AKI). METHODS: Clinical data of AKI patients in the intensive care unit (ICU) were retrospectively analyzed from the American Medical Information Mart of Intensive Care-IV (MIMIC-IV), including demographic data, acute physiology score (APS), comorbidities, vital signs, laboratory indicators, treatment status, ICU length of stay, and outcome indicators. The main outcome measure is ICU mortality. AKI patients were divided into Alb infusion group and Alb non infusion group based on whether they received Alb treatment. Multiple imputation was used to process missing data and eliminate variables that missing more than 30%. To ensure the stability of the results, propensity score matching (PSM) and inverse probability weighting (IPW) were used to correct the results. Using Kaplan-Meier survival curve and Cox proportional hazards regression model to evaluate the effect of Alb infusion on ICU survival rate in AKI patients. Perform subgroup analysis based on patient age, gender, and comorbidities to evaluate the prognostic effects of Alb on different patient subgroups. RESULTS: A total of 6 390 AKI patients were included, including 1 721 in the Alb infusion group and 4 669 in the Alb non infusion group. After adjusting for key covariates in the Cox regression model, compared with the Alb non infusion group, patients in the Alb infusion group were significantly younger in age, with APS III score, proportion of vasoactive drugs and continuous renal replacement therapy (CRRT) use, sepsis proportion, heart rate, respiratory frequency, aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatinine (Cr), lactic acid (Lac), and arterial partial pressure of carbon dioxide (PaCO₂) levels significantly higher. The proportion of hypertension, myocardial infarction, and congestive heart failure, as well as blood pressure, urine output, platelet count (PLT), and Alb levels were significantly lower. The results of univariate and multivariate Cox regression analysis on the raw data showed that the risk of death in the Alb infusion group was significantly lower than that in the Alb non infusion group [hazard ratio (HR) = 0.69, 95% confidence interval (95%CI) was 0.60-0.80, all P < 0.05]. The results after propensity score matching (PSM) and inverse probability weighting (IPW) processing are consistent with the original data trend (both P < 0.05). The Kaplan-Meier survival curve showed that the cumulative survival rate during ICU stay in the Alb infusion group was significantly higher than that in the Alb non infusion group (24.48% vs. 12.17%, Log-Rank test: χ² = 74.26, P < 0.05). Subgroup analysis shows that Alb infusion has a more significant survival benefit for AKI patients who use vasoactive drugs, have concurrent sepsis, and do not have liver disease. CONCLUSION Albumin infusion can decrease the ICU mortality of AKI patients.

Objective: Sentinel lymph node biopsy (SLNB) has improved detection of low-volume node metastasis (LVNM) in endometrial cancer (EC), but its prognostic significance and the need for adjuvant therapy (AT) remain unclear. Methods: A comprehensive search was performed until August 31, 2024 in multiple databases and sources. From 21 studies, 65,228 apparent early-stage EC patients were identified: 370 with macrometastases (MAC), 526 with micrometastases (MM), 2,138 with isolated tumor cells (ITCs), and 62,194 with negative nodes. Results: Findings indicated: 1) The MM group had a lower risk of recurrence or progression (R/P) than the MAC group (risk ratio [RR]=0.49; 95% confidence interval [CI]=0.31–0.78;p=0.002), higher risk than the negative nodes group (RR=2.07; 95% CI=1.59–2.68; p<0.001), and similar risk to the ITC group (RR=0.67; 95% CI=0.44–1.02; p=0.060). 2) The MM group had higher 3-year progression-free survival (PFS) (RR=1.36; 95% CI=1.21–1.52; p<0.001) and overall survival (OS) (RR=1.22; 95% CI=1.09–1.37; p<0.001) than the MAC group, similar to the ITC and negative nodes groups. 3) The ITC group had a lower R/P risk and higher 3-year PFS/OS than the MAC group, similar to the negative nodes group. 4) AT reduced the R/P risk in the MM group (RR=0.41; 95% CI=0.22–0.76; p=0.005) and increased 3-year OS in the ITC group (RR=1.06; 95% CI=1.04–1.08; p<0.001). Conclusion Early-stage EC with LVNM had better prognostic outcomes than MAC, and AT may improve outcomes of LVNM patients. More evidence from prospective randomized controlled trials is needed to confirm these findings due to the inherent biases of retrospective studies.

Objective To investigate the clinical characteristics and influencing factors of moderate-to-severe pulmonary ventilation dysfunction in occupational pneumoconiosis (hereinafter referred to as "pneumoconiosis") patients complicated with pulmonary tuberculosis. Methods A total of 136 male pneumoconiosis patients complicated with pulmonary tuberculosis suffering different degrees of pulmonary ventilation dysfunction were selected as the study subjects using the judgmental sampling method. Patients were divided into mild dysfunction and moderate-to-severe dysfunction groups based on the degrees of pulmonary ventilation dysfunction. Clinical data from patients of these two groups were collected, and influencing factors of pulmonary ventilation dysfunction were analyzed. Results The prevalence of mild dysfunction and moderate-to-severe dysfunction among the study subjects was 39.0% and 61.0%, respectively. The proportion of patients with moderate-to-severe pulmonary ventilation dysfunction increased with the progression of pneumoconiosis (P<0.05). Patients in moderate-to-severe dysfunction group had higher rates of dyspnea, elevated C-reactive protein, coexisting chronic obstructive pulmonary disease (COPD), and a history of lung infections within the past two years compared with those in the mild dysfunction group (all P<0.05). The result of multivariate logistic regression analysis showed that the degree of pneumoconiosis, complicated with COPD, and a history of lung infections within the past two years were risk factors for moderate-to-severe pulmonary ventilation dysfunction (all P<0.05). Specifically, higher degree of pneumoconiosis was associated with a greater proportion of moderate-to-severe dysfunction, and patients complicated with COPD or had a history of lung infections within the past two years were more likely to experience severe pulmonary ventilation dysfunction. Conclusion The degree of pneumoconiosis, complicated with COPD, and a history of lung infections within the past two years are influencing factors of moderate-to-severe pulmonary ventilation dysfunction in patients with pneumoconiosis combined with pulmonary tuberculosis. Early detection of pneumoconiosis progression, timely diagnosis of COPD and lung infections, and appropriate treatment such as antifibrotic agents, inhaled bronchodilators, and anti-infective therapies are recommended.

Outer membrane vesicles (OMVs) are nanoscale vesicles secreted by Gram-negative bacteria. As a unique bacterial secretion, OMV secretion can help bacteria maintain the outer membrane stability or remove harmful substances. Studies have shown that local separation of outer membrane and peptidoglycan layers led by abnormalities in outer membrane protein function, abnormal structure or excessive accumulation of LPS, and erroneous accumulation of phospholipids in the outer leaflet, which can all lead to bacterial outer membrane protrusion and eventually bud formation of OMVs. Since OMVs are mainly composed of bacterial outer membrane and periplasmic components, the pathogen associated molecular patterns (PAMPs) on their surface can trigger strong immune responses. For example, OMVs can recruit and activate neutrophils, polarize macrophages to secrete large amounts of inflammatory factors. More importantly, OMVs can act as adjuvants to induce dendritic cell (DC) maturation to enhance adaptive immune response in the body. At the same time, OMVs are derived from bacteria, which make it easy to modify. The methods by genetic engineering and others can improve their tumor targeting, give them new functions, or reduce their immunotoxicity, which is conducive to their application in tumor therapy. OMVs not only induce apoptosis or pyroptosis of tumor cells, but also regulate the host immune system, which makes OMVs themselves have a certain killing effect on tumors. In addition, the tendency of neutrophils to inflammatory tumor sites and the formation of neutrophil extracellular traps enable OMVs to target tumor sites, and the suitable size and the characteristic that they are easily taken up by DCs give OMVs a certain lymphatic targeting ability. Therefore, OMVs are often employed as excellent drug or vaccine carriers in tumor therapy. This review mainly discusses the biological mechanism of OMVs, the regulatory effects of OMVs on immune cells, the functional modification strategies of OMVs, and their research progress in tumor therapy.
