Objective: To explore the network structure of middle school students basic psychological needs and psychological behavioral problems, and identify the core nodes within the network, as well as examine demographic subgroup differences, so as to provide support for targeted mental health interventions for adolescents. Methods: In September and October of 2023, a total of 2 000 junior and senior high school students were selected with multistage cluster random sampling from 8 schools in Jiaojiang District and Tiantai County, Taizhou City. An online self administered questionnaire was used to assess emotional and behavioral problems, perceived autonomy, self awareness, loneliness, and social support. The instruments included the Strengths and Difficulties Questionnaire (SDQ), Perceived Choice and Awareness of Self Scale (PCASS), Mental Health Literacy Questionnaire (MHLQ), University of California,Los Angeles Loneliness Scale (UCLA-LS), and the Multidimensional Scale of Perceived Social Support (MSPSS). A network analysis approach was employed to construct a network representing adolescents basic psychological needs and psychological behavioral problems, focusing on centrality measures and demographic subgroup differences. Results: A total of 418 students (20.9%) reported abnormal emotional and behavioral problems. Perceived autonomy and competence were negatively correlated with emotional problems (weights: 0.12, 0.14) and hyperactivity (weights: 0.10, 0.16). Social support showed negative correlation with peer relationship issues, hyperactivity, and conduct problems (weights: 0.16, 0.13, 0.10). Loneliness was positively correlated with emotional symptoms and peer relationship problems (weights: 0.28, 0.18). In the overall network, perceived relationships (social support and loneliness), emotional symptoms, and hyperactivity emerged as central nodes. Significant differences in network structure were observed between gender subgroups ( P =0.02). Girls internalizing issues were more influenced by loneliness and perceived autonomy frustration, while social support exhibited higher centrality in boys. Conclusions Perceived relationships, emotional problems, and hyperactivity are key nodes in the network of adolescents basic psychological needs and psychological behavioral problems. Loneliness demonstrates a prominent influence within the network, and the overall network exhibits gender differences.

ObjectivesTo investigate the molecular epidemiological characteristics of HIV-1 infection among men who had sex with men (MSM) in Taizhou City, Zhejiang Province, and to provide a scientific reference for acquired immune deficiency syndrome prevention and control efforts. MethodsThe research subjects were all newly reported MSM population in Taizhou City from 2020 to 2023. Blood samples without antiviral therapy were collected. The HIV-1 pol gene was amplified and sequenced, and the sequences were submitted to the Stanford University drug resistance database to identify the mutation sites and drug resistance. MEGA 11.0 software was used to analyze the nucleic acid sequences, construct phylogenetic tree, and calculate genetic distance of gene sequences. The molecular transmission network diagram of HIV-1 was constructed using Cytoscape_v3.10.1, and the influencing factors of network entry were analyzed by logistic regression. ResultsA total of 363 newly reported HIV-infected MSM patients were included, with a median age [M (P₂₅, P₇₅)] of 34 (26,47) years old. The majority had an educational level of junior high school or below (55.65%). A total of eight subtypes were found, mainly CRF07_BC and CRF01_AE. The primary drug resistance rate was 10.47% (38/363). The optimal molecular network gene distance was 0.019, with a network access rate of 42.70% (155/363), and a total of 47 molecular clusters were formed. Multivariate logistic analyses showed that compared with the CRF01_AE subtype, the clustering risk of CRF07_BC subtype was higher (OR=1.916, 95%CI: 1.191‒3.109), cases with drug resistance had a higher risk of cluster formation than those without drug resistance (OR=2.011, 95%CI: 1.006‒4.080), and recent infected patients had a lower risk of entering the largest molecular cluster than long-term infected patients (OR=0.376, 95%CI: 0.137‒0.928). ConclusionThe newly diagnosed infections among the MSM population are active in Taizhou City, Zhejiang Province, with a high level of primary drug resistance. Individuals carrying drug-resistant strains are more likely to cluster. Drug resistance monitoring should be strengthened to prevent further spread of drug-resistant strains in the network.

Background and Aims:Minimally invasive surgery,represented by laparoscopic techniques,plays a vital role in the treatment of gastric cancer.However,postoperative infectious complications remain a key factor affecting patient recovery and prognosis.This study was performed to identify the risk factors associated with early(≤1 month)infectious complications after laparoscopic surgery for gastric cancer,providing a reference for clinical prevention strategies.Methods:A retrospective analysis was conducted on 1 572 patients who underwent laparoscopic surgery for gastric cancer at the First Affiliated Hospital of Xi'an Jiaotong University from March 2020 to February 2024.Patients were divided into infection and non-infection groups based on the occurrence of postoperative infectious complications.Univariate and multivariate Logistic regression analyses were performed to identify related risk factors.Results:Among the 1 572 patients,194 cases(12.3％)developed early postoperative infectious complications,including intra-abdominal infections(4.1％),surgical site infections(3.7％),and pulmonary infections(5.6％).Univariate analysis revealed that a history of diabetes,pulmonary disease,smoking,and preoperative anemia and hypoalbuminemia were significantly associated with postoperative infections(all P＜0.05).Multivariate analysis indicated that a history of diabetes(OR=6.927,95％CI=4.194-12.935),smoking(OR=3.079,95％CI=2.261-4.913),and preoperative albumin＜35 g/L(OR=0.572,95％CI=0.302-1.578)were independent risk factors for early postoperative infectious complications.Conclusion:A history of diabetes,smoking,and preoperative hypoalbuminemia are closely associated with the occurrence of early postoperative infectious complications after laparoscopic gastric cancer surgery.Clinical attention should be paid to perioperative metabolic,nutritional,and lifestyle management,and early intervention for high-risk patients may help reduce the incidence of complications,improve recovery,and enhance treatment outcomes.

Objective:To determine the prevalence and associates of hyperuricemia (HUA) among the middle- and older-aged population of the island and mountainous areas in Taizhou City of Zhejiang Province.Methods:A cross-sectional study was conducted on individuals aged 45 and above in the island and mountainous area of Taizhou City. The study included questionnaires, physical examinations, and laboratory tests. Data were primarily collected on sociodemographic characteristics, chronic disease history, lifestyle factors, waist circumference, blood pressure, and serum uric acid levels. The association between hyperuricemia and these factors was analyzed by logistic regression.Results:A total of 971 individuals were included in the study, comprising 468 from island and 503 from mountainous area. The prevalence of hyperuricemia was 17.9%, with a significantly higher prevalence in the island area (25.6%) compared to the mountainous area (10.7%). Stratified by gender and age, differences in the prevalence of hyperuricemia between island and mountainous areas were observed in males aged 55 to 64, females aged 45 to 54, 55 to 64, 75 and above (all P<0.05). Multiple logistic regression analysis showed that high intake of sea food (>3 times/week) was positively associated with hyperuricemia ( OR=2.10, 95% CI:1.33-3.34). Furthermore, separate regionally stratified logistic regression analyses showed that in the island area, male gender ( OR=3.15, 95% CI:1.78-5.66), central obesity ( OR=2.38, 95% CI:1.46-3.93), and hypertriglyceridemia ( OR=2.00, 95% CI:1.22-3.30) were positively correlated with hyperuricemia (all P<0.05). In the mountainous area, the age group of 65 and above ( OR=3.50, 95% CI:1.09-12.50), male ( OR=6.79, 95% CI:2.87-17.81), those employed in enterprises and institutions ( OR=6.57, 95% CI:1.92-23.73) and hypertension ( OR=3.68, 95% CI:1.66-8.87) were positively correlated with hyperuricemia (all P<0.05). Conclusions:The prevalence of hyperuricemia among the middle- and older-aged population in the island of Taizhou City is significantly higher than that in the mountainous areas. Targeted comprehensive behavioral interventions such as routine screening of chronic diseases, low-fat diet, alcohol control, reduced seafood intake, enhanced exercise, weight management, and blood pressure control are warranted.

Objective:To describe the prevalence of non-alcoholic fatty liver disease (NAFLD) in people living with HIV in Taizhou, Zhejiang Province, and identify the factors associated with NAFLD in this population.Methods:A cross-sectional survey was conducted from 2021 to 2023. Based on the routine follow-up management of people living with HIV, liver ultrasound examination, physical examination and laboratory test were conducted to collect the information about the diagnosis of NAFLD and biochemical indicators in this population. Logistic regression model was used to identify the factors associated with the prevalence of NAFLD.Results:In the 2 550 study participants, the prevalence of NAFLD was 21.5% (548/2 550), abnormal liver function was found in 23.7% (604/2 550) of the study participants, and liver fibrosis was found in 45.2% (1 152/2 550) of the study participants. Multivariable logistic regression analyses showed that being women (a OR=0.55, 95% CI: 0.42-0.73), being overweight or obese (a OR=3.22, 95% CI: 2.59-4.01), having diabetes (a OR=3.37, 95% CI: 2.15-5.29), having dyslipidemia (a OR=2.96, 95% CI: 2.25-3.89), CD4 + T lymphocyte (CD4) counts <200 cells/μl (a OR=0.61, 95% CI: 0.42-0.88), and receiving Efavirenz (EFV) + Lamivudine (3TC) + Zidovudine (AZT) for antiretroviral therapy (ART)(a OR=1.52, 95% CI: 1.17-1.98) were associated with NAFLD. NAFLD was positively associated with abnormal liver function (a OR=2.01, 95% CI: 1.60-2.52) and inversely associated with liver fibrosis (a OR=0.76, 95% CI: 0.59-0.98). The 45-59 age group (a OR=7.05, 95% CI: 5.65-8.80), CD4 counts <200 cells/μl (a OR=1.45, 95% CI: 1.06-1.97) and receiving Nevirapine (NVP)+3TC+AZT of ART (a OR=1.87,95% CI: 1.44-2.43) were the main factors associated with liver fibrosis. Conclusions:The prevalence of NAFLD in people living with HIV Taizhou was more than 20.0%, with a significant proportion of them having abnormal liver function and liver fibrosis. Being overweight or obese, suffering from diabetes, having dyslipidemia, low CD4 counts, and receiving specific ART were associated with NAFLD. NAFLD, CD4 counts and specific ART were the main factors associated with abnormal liver function and liver fibrosis.

Objective:To analyze the incidence and risk factors of malignant tumors among HIV-infected patients in Taizhou, Zhejiang Province.Methods:The data were collected from the China Information System for Disease Control and Prevention and the Taizhou Chronic Disease Information Management System. A retrospective cohort study design was used. The subjects were HIV-infected patients who had their household registration in Taizhou from 2005 to 2023 and participated in the follow-up. The observation period was until December 31, 2024. The standardized incidence ratios (SIR) of malignant tumors among HIV-infected patients were analyzed. Cox proportional hazards regression model was used to analyze the influencing factors of malignant tumor incidence.Results:A total of 3 593 HIV-infected patients were included, of whom 292 had malignant tumors. The proportions of AIDS-defining malignancies and non-AIDS-defining malignancies were 12.33% (36/292) and 87.67% (256/292), respectively. The proportion of malignant tumors before and after AIDS confirmation was 43.49% (127/292) and 56.51% (165/292), respectively. 3 466 HIV-infected patients were included in the follow-up cohort, with a total follow-up of 24 968.59 person-years. The incidence rate of malignant tumors in patients with HIV infection was 658.46 per 100 000 (SIR=1.89, 95% CI: 1.61-2.20). The SIR of malignant tumors showed an upward trend with the increase of time. The results of Cox proportional hazards regression model analysis showed that HIV-infected patients in the age groups of 45-59 and ≥60 years (a HR=2.58, 95% CI: 1.26-5.28; a HR=5.00, 95% CI: 2.38-10.51) were more likely to develop malignant tumors. HIV-infected patients with an educational level of senior high school or above (a HR=0.52, 95% CI: 0.29-0.95) and those in the first CD4 +T lymphocyte/CD8 +T lymphocyte count ratio ≥0.5 (a HR=0.52, 95% CI: 0.28-0.97) were less likely to develop malignant tumors. Conclusions:From 2005 to 2023, the incidence of malignant tumors among HIV-infected people in Taizhou was higher than that of the general population, and most of them were non-AIDS-defining malignancies. It is necessary to strengthen the early screening and diagnosis of malignant tumors among HIV-infected patients.

Objective:To investigate the life expectancy of antiretroviral treatment (ART) HIV-infected patients and its trends in Taizhou City, Zhejiang Province from 2014 to 2023.Methods:The data were obtained from the China Information System for Disease Control and Prevention , and the study subjects were HIV-infected patients received ART in Taizhou City. An abbreviated life expectancy table was prepared based on Chiang's method to analyze the differences in life expectancy of HIV-infected patients receiving ART in Taizhou City with different characteristics in 2023 and to compare the trends in life expectancy of patients with different CD4 +T lymphocytes (CD4) counts at the time of initiation of ART from 2014 to 2023. Results:A total of 4 825 patients were enrolled in this study, with a cumulative follow-up of 276 648.56 person-years, and a case-fatality rate of 18.07 (95% CI: 16.48-19.65) /1 000 person-years. In 2023, male patients had lower life expectancy than females in all age groups, and those who were married had higher life expectancy than those who were unmarried and those who were divorced or widowed; patients who had been transmitted heterosexually had lower life expectancy than those who had been transmitted through homosexual transmission. Patients with different CD4 counts at the time of initiating ART had different life expectancies in all age groups. The life expectancy of patients with CD4 counts ≥350 cells/μl when initiating the treatment was higher than that of patients with CD4 counts <200 cells/μl in all age groups. The life expectancy of HIV-infected patients on ART at age 20 and 50 increased from 39.0 years and 19.1 years in 2014 to 46.0 years and 24.1 years in 2023, respectively, with an average annual percentage change of 2.43% (95% CI: 0.81%-4.07%) and 3.34% (95% CI: 1.17%-5.56%). The change in life expectancy was similar for patients with CD4 counts ≥350 cells/μl and 200-349 cells/μl at the time of initiating treatment in 2016-2023, and was higher than that for patients with CD4 counts <200 cells/μl. The rate of increase in life expectancy for patients at age 50 was higher than that at age 20 for all CD4 counts. Conclusions:The rising trend of life expectancy among HIV-infected patients on ART in Taizhou City is obvious. But the disparity between patients with different characteristics is obvious, especially among patients with baseline CD4 counts <200 cells/μl, suggesting the importance of expanded testing, early diagnosis and timely initiation of ART to improve the life expectancy of HIV-infected patients.
