Occupational hazards pose a major public health challenge that seriously endangers the health of the working population. As a statutory key component of occupational health work, occupational health risk assessment urgently requires more attention. Currently, commonly used occupational health risk assessment methods exhibit notable deficiencies such as insufficient comprehensive assessment capabilities and limited applicability. The absence of assessment methods that accurately align with occupational health practices has constrained the depth and breadth of occupational health risk assessment in China, resulting in inadequate risk identification and significant deficiencies in social service provision, decision-making support, and health protection. Meanwhile, under the current assessment system, the occupational health big data obtained from risk assessments, occupational health examinations, biological monitoring, and other sources suffer from issues such as fragmented resources and low utilization rates. As a result, existing systems are unable to effectively support critical operational needs, including accurate risk early warning, timely risk response, and refined risk management. This study systematically reviewed the common occupational health risk assessment methods and the current status of occupational health risk assessment and big data applications in China, identified existing shortcomings, proposed a comprehensive risk assessment and risk prediction-early warning scheme based on the application of occupational health big data. The scheme is expected to provide theoretical foundations and methodological references for advancing comprehensive risk assessment of occupational health through big data analytics, and to enhance the level of occupational health management, thereby safeguarding worker health and promoting sustainable socioeconomic development.

Approximately 10% of the global adult population has diabetes, with accumulating evidence linking suboptimal vitamin D levels to an increased risk of type 2 diabetes and its complications. Current clinical studies suggest that vitamin D supplementation may enhance insulin sensitivity and improve glycemic control, prompting significant interest in its potential as a therapeutic intervention. However, further high-quality, large-scale randomized controlled trials are required to validate its efficacy in glucose metabolism regulation and clarify the underlying molecular mechanisms. These investigations will provide critical evidence to inform precision medicine approaches for diabetes prevention and management.

OBJECTIVE: To identify prognostic genes associated with lysosome-dependent cell death (LDCD) in patients with gastric cancer (GC). METHODS: Differentially expressed genes (DEGs) were identified using The Cancer Genome Atlas - Stomach Adenocarcinoma. Weighted gene co-expression network analysis was performed to identify the key module genes associated with LDCD score. Candidate genes were identified by DEGs and key module genes. Univariate Cox regression analysis, and least absolute shrinkage and selection operator regression and multivariate Cox regression analyses were performed for the selection of prognostic genes, and risk module was established. Subsequently, key cells were identified in the single-cell dataset (GSE183904), and prognostic gene expression was analyzed. Cell proliferation and migration were assessed using the Cell Counting Kit-8 assay and the wound healing assay. RESULTS: A total of 4,465 DEGs, 95 candidate genes, and 4 prognostic genes, including C19orf59, BATF2, TNFAIP2, and TNFSF18, were identified in the analysis. Receiver operating characteristic curves indicated the excellent predictive power of the risk model. Three key cell types (B cells, chief cells, and endothelial/pericyte cells) were identified in the GSE183904 dataset. C19orf59 and TNFAIP2 exhibited predominant expression in macrophage species, whereas TNFAIP2 evolved over time in endothelial/pericyte cells and chief cells. Functional experiments confirmed that interfering with C19orf59 inhibited proliferation and migration in GC cells. CONCLUSION C19orf59, BATF2, TNFAIP2, and TNFSF18 are prognostic genes associated with LDCD in GC. Furthermore, the risk model established in this study showed robust predictive power.

OBJECTIVE: The objective of our study was to evaluate the vaccine effectiveness (VE) of the pentavalent rotavirus vaccine (RV5) among < 5-year-old children in three provinces of China during 2020-2024 via a propensity score-matched test-negative case-control study. METHODS: Electronic health records and immunization information systems were used to obtain data on acute gastroenteritis (AGE) cases tested for rotavirus (RV) infection. RV-positive cases were propensity score matched with RV-negative controls for age, visit month, and province. RESULTS: The study included 27,472 children with AGE aged 8 weeks to 4 years at the time of AGE diagnosis; 7.98% (2,192) were RV-positive. The VE (95% confidence interval, CI) of 1-2 and 3 doses of RV5 against any medically attended RV infection (inpatient or outpatient) was 57.6% (39.8%, 70.2%) and 67.2% (60.3%, 72.9%), respectively. Among children who received the 3rd dose before turning 5 months of age, 3-dose VE decreased from 70.4% (53.9%, 81.1%) (< 5 months since the 3rd dose) to 63.0% (49.1%, 73.0%) (≥ 1 year since the 3rd dose). The three-dose VE rate was 69.4% (41.3%, 84.0%) for RVGE hospitalization and 57.5% (38.9%, 70.5%) for outpatient-only medically attended RVGE. CONCLUSION Three-dose RV5 VE against rotavirus gastroenteritis (RVGE) in children aged < 5 years was higher than 1-2-dose VE. Three-dose VE decreased with time since the 3rd dose in children who received the 3rd dose before turning five months of age, but remained above 60% for at least one year. VE was higher for RVGE hospitalizations than for medically attended outpatient visits.

Gastric cancer with peritoneal metastasis (GCPM) is a common and lethal manifestation of advanced gastric cancer, with a median survival of only 5-11 months. This consensus was developed by 30 experts from Asia (China, Japan, Korea, and Singapore) using the Delphi method and the GRADE evidence grading system. A total of 29 statements were formulated, covering the diagnosis and assessment of GCPM, indications for laparoscopic exploration and NIPS (normothermic intraperitoneal and systemic treatment), treatment regimens, prevention and management of complications, criteria for conversion surgery, and postoperative intraperitoneal therapy. The consensus aims to standardize clinical practice and improve the prognosis of patients with GCPM.

Objective:To investigate the current state of death cognition among healthcare providers in hematology department and their attitudes toward hospice care for patients with hematologic malignancies.Methods:A cross-sectional investigation study was conducted. A total of 198 medical staff in hematology department of 4 teaching hospitals, including the First School of Clinical Medicine of Guangdong Medical University, Fujian Medical University Union Hospital, the Affiliated Hospital of Putian University and the First Affiliated Hospital of Gannan Medical University from March 2024 to June 2024 were selected as the investigation subjects. The general situation and background of medical staff in hematology department were investigated by using the "General Sociological Questionnaire". "Death Attitude Description Scale (Chinese version)" was used to investigate the status of death cognition among medical staff in hematology department. "Frommelt Attitudes Toward Care of the Dying Scale Form B (Chinese version)" was used to investigate the hospice care attitude of medical staff in hematology department. The survey results of doctors and nurses were compared.Results:There were 105 doctors and 93 nurses in hematology department included in this study. A total of 198 qualified "General Sociology Questionnaires" were collected. After excluding 6 unqualified questionnaires, 192 copies of "Death Attitude Description Scale (Chinese version)" and "Frommelt Attitudes Toward Care of the Dying Scale Form B (Chinese version)" were collected. There were statistically significant differences in gender, educational background, political status and experience of taking care of terminally ill patients between doctors and nurses (all P < 0.05). The scores of approaching acceptance, neutral acceptance, death escape, death fear and flight acceptance were (4.35±0.37), (4.03±0.51), (2.98±0.62), (2.54±0.29) and (2.19±0.42) points, respectively in the doctor group; the corresponding scores were (3.12±0.41), (3.89±0.46), (2.66±0.63), (2.81±0.57) and (2.37±0.65) points, respectively in the nurse group, and the differences between the 2 groups were statistically significant (all P < 0.05). The total score of hospice care attitude of doctors in hematology department was (108±15) points, and that of nurses was (116±13) points, and the difference was statistically significant ( t = -3.61, P < 0.001). The hospice care attitude of doctors and nurses towards patients with hematologic malignancies is generally between positive and neutral. The nurse group showed more recognition of the positive role of the patient's family members in the process of hospice care, and the doctor group showed more recognition of the promoting role of medical staff in hospice care. There were statistically significant differences in hospice care attitude scores of medical staff in hematology department to patients with different occupational background, gender, age, place of residence, family discussion about death, whether the only child, whether they had the experience of taking care of terminally ill patients, and whether they suffered from serious illness and religious belief (all P < 0.05). Conclusions:The death cognition of medical staff in hematology department is neutral, and they show a certain sense of hospice care.

Objective To investigate the impact of phase Ⅱ cardiac rehabilitation on the rehabilitation needs and physical activity status of patients after coronary heart disease intervention.Methods A total of 90 patients with coronary heart disease who underwent percutaneous coronary intervention(PCI)in the Coronary Heart Disease Center of the hospital from August 2023 to August 2024 were selected as the research subjects.They were subjected to a 12-week standardized phase Ⅱ cardiac rehabilitation training.General data survey forms,cardiac rehabilitation scales,and the International Physical Activity Questionnaire were used for scale surveys to understand the patients' needs before and after rehabilitation and their weekly physical activity en-ergy expenditure.The cardiopulmonary exercise test gold standard,which reflects exercise capacity through three indicators-maximum oxygen uptake(VO2 max),anaerobic threshold(AT),and metabolic equivalents(MET),were used to compare the physical activity status before and after cardiac rehabilitation.Results Compared with before the implementation,after the implementation of cardiac rehabilitation,the autonomy score in-creased(21.36±1.85 vs.16.73±3.28),the process anxiety(12.60±3.87 vs.14.27±2.12)and outcome anxiety scores(2.31±1.76 vs.4.56±3.56)decreased,the level of low-intensity physical activity decreased[(2 711.62±1 487.09)min/week vs.(3 845.97±2 083.71)min/week],the levels of moderate-intensity[(1 314.67±783.54)min/week vs.(686.22±126.79)min/week],high-intensity[(1 861.33±798.27)min/week vs.(112.00±40.77)min/week],and total physical activity increased[(5 887.62±2 843.54)min/week vs.(4 644.19±2 287.16)min/week].The levels of VO2 max[(28.11±14.28)mL·min-1·kg-1 vs.(23.82±12.34)mL·min-1·kg-1],AT[(16.06±5.41)mL·min-1·kg-1 vs.(13.53±4.56)mL·min-1·kg-1],and MET[(6.89±1.59)mL·min-1·kg-1 vs.(5.78±1.21)mL·min-1·kg-1]all in-creased,with statistically significant differences(P＜0.05).Conclusion Phase Ⅱ rehabilitation after PCI can effectively improve patients' physical activity levels.
