Objective:To analyze the latent prevalence of hepatitis B and type 2 diabetes and their correlation through an observational study.Methods:This study used a case-control design. The cases with diabetes were recruited through the diabetes management system and village doctors, while the controls without diabetes were screened from volunteers recruited by village health clinics. Capillary blood samples were collected from the study participants for the measurement of real-time blood glucose level, and venous blood samples were taken from them for the detections of HBV serological markers. Firth logistic regression model was used to fit the relationship between HBsAg positive status and diabetes status.Results:The study included 1 218 diabetes patients, 62 patients with impaired fasting glucose and 491 cases without diabetes. In the cases without diagnosis of diabetes, 11.15% had impaired fasting blood glucose and 4.43% had diabetes. Among those who reported no or unknown diagnosis of hepatitis B, 1.73% were positive for HBsAg, while 18.80% were positive for both HBV core antibody and surface antibody, indicating latent infection of hepatitis B virus. In the non-diabetes group, 0.81% reported hepatitis B history, and in the diabetes group, 2.76% reported hepatitis B history. After adjustment, the HBsAg positive rate was higher in the diabetes group ( OR=2.90, 95% CI: 1.21-6.91). Conclusions:Both diabetes and hepatitis B exhibited a high degree of latent prevalence. The HBsAg positive rate was significantly higher in those with diabetes than in those without diabetes, indicating a potential correlation. These findings highlighted the importance of strengthened screening and management of comorbidities.

Objective:Exploration of the immunogenicity and persistence of three different immunization regimens of hepatitis B vaccines in diabetic patients.Methods:Participants with diabetes and non-diabetic individuals were recruited from study sites and assigned to different vaccination regimens: the diabetic group (①D60Yeast0-1: received 60 μg Saccharomyces cerevisiae-derived recombinant HBV vaccine on a 0-1-month schedule; ②D20Yeast0-1-6: received 20 μg Saccharomyces cerevisiae-derived recombinant HBV vaccine on a 0-1-6-month schedule; ③D20CHO0-1-6: received 20 μg Chinese hamster ovary (CHO) cell-derived recombinant HBV vaccine on a 0-1-6-month schedule) and the non-diabetic group (ND20Yeast0-1-6: non-diabetic individuals received 20 μg Saccharomyces cerevisiae-derived recombinant HBV vaccine on a 0-1-6-month schedule). Venous blood samples were collected at 1,12, and 48 months post-full vaccination to measure anti-HBs levels. Differences in immunogenicity between diabetic and non-diabetic groups, as well as among diabetic subgroups, were analyzed.Results:This study enrolled a total of 564 subjects. In the D20CHO0-1-6 group, the seroconversion rate decreased from 90.72% (95% CI: 84.84%-96.60%) at 1 month to 74.23% (95% CI: 65.37%-83.08%) at 48 months, and the antibody geometric mean concentration (GMC) decreased from 676.08 (95% CI: 389.05- 1 148.20) mIU/ml at 1 month to 33.11 (95% CI: 23.44-46.77) mIU/ml at 48 months. In the D20Yeast0-1-6 group, the seroconversion rate declined from 93.81% (95% CI: 89.29%-98.32%) at 1 month to 63.72% (95% CI: 54.71%-72.72%) at 48 months, with antibody GMC dropping from 630.96 (95% CI: 407.40-954.99) mIU/ml to 25.70 (95% CI: 17.78-38.02) mIU/ml over the same period. For the D60Yeast0-1 group, seroconversion rate fell from 82.03% (95% CI: 75.29%-88.77%) to 56.25% (95% CI: 47.54%-64.96%), and antibody GMC decreased from 81.28 (95% CI: 51.29-128.82) mIU/ml to 15.49 (95% CI: 11.75-20.89) mIU/ml between 1 and 48 months. The ND20Yeast0-1-6 group (non-diabetic control) exhibited a higher initial seroconversion rate of 97.56% (95% CI: 94.80%- 100.00%) at 1 month, but it still declined to 76.42% (95% CI: 68.82%-84.03%) at 48 months, with antibody GMC decreasing from 1 318.30 (95% CI: 912.01- 1 905.50) mIU/ml to 34.67 (95% CI: 25.12-47.86) mIU/ml. Multivariate analysis on factors influencing the GMC of antibodies revealed statistically significant differences in antibody GMC between the D20Yeast0-1-6 group and ND20Yeast0-1-6 group at 12 months (a OR=0.73, 95% CI: 0.58-0.93) and 48 months (a OR=0.79, 95% CI: 0.63-0.99) post-vaccination (all P<0.05). As for the diabetic population, when compared with the D20Yeast0-1-6 group, the D60Yeast0-1 group also showed statistically significant differences in antibody GMC at 12 months (a OR=0.57, 95% CI: 0.44-0.74) and 48 months (a OR=0.60, 95% CI: 0.47-0.76)(all P<0.05). Conclusions:The seroconversion rate and antibody GMC gradually decreased over time (1, 12, and 48 months) in the four groups. Diabetic patients showed poor immunogenicity and persistence to hepatitis B vaccines. The immunogenicity and persistence of hepatitis B vaccination in diabetic patients were associated with vaccine type, antigen dose, and vaccination regimen. The CHO cell-recombinant hepatitis B vaccine demonstrated better performance in terms of immunogenicity and persistence among the diabetic population.

Objective:To study the health-related quality of life (HRQOL) and influencing factors of echinococcosis surgical patients included in the project management in Jingyuan County since the implementation of the Central Transfer Payment for Local Echinococcosis Prevention and Control Project (hereinafter referred to as the Echinococcosis Prevention and Control Project).Methods:Surgical patients included in the management of Echinococcosis Prevention and Control Project in Jingyuan County from January 1, 2009 to December 31, 2022 were selected as study subjects for a door-to-door questionnaire survey to collect basic information, medical treatment and diagnosis, surgical situation, postoperative follow-up and management situation, preoperative and postoperative HRQOL. Multivariate logistic regression was employed to analyze the influencing factors of HRQOL in echinococcosis surgical patients.Results:A total of 111 echinococcosis patients undergoing surgery were included, with a first visit duration [ M ( Q1, Q3)] of 8.0 (5.0, 12.0) years from symptom onset to initial consultation, and a surgical treatment duration of 8.0 (5.0, 12.0) years from diagnosis to surgical intervention. The cure rate based on postoperative efficacy observation was 81.08% (90/111). There was no statistically significant differences in the distribution of preoperative and postoperative mobility, self-care, daily activities, anxiety or depression among echinococcosis patients undergoing surgery ( P > 0.05). However, significant differences were observed in the distribution of pain or discomfort and health status scores ( P < 0.001). The results of ordinal logistic regression analysis showed that preoperative age [≥61 years old, OR (95% CI) = 0.06 (0.01, 0.56), P = 0.014], preoperative concomitant hypertension (grade Ⅱ), diabetes, and heart disease [ OR (95% CI) = 13.15 (1.80, 96.13), 57.69 (2.05, 1 620.13), 10.90 (1.27, 93.90), P < 0.05], initial lesion location in the abdominal cavity and the lesion in two or more locations [ OR (95% CI) = 30.83 (1.05, 902.45), 114.25 (7.24, 1 801.75), P < 0.05] were independent influencing factors for preoperative HRQOL in patients with echinococcosis. Postoperative comorbidities of hypertension (grade Ⅱ) and diabetes [ OR (95% CI) = 42.77 (2.39, 766.21), 901.40 (4.64, 1 740.94), P < 0.05], and postoperative complications [ OR (95% CI) = 130.61 (6.27, 2 722.24), P = 0.002] were independent influencing factors for postoperative HRQOL in patients with echinococcosis. Conclusions:The health status of patients with echinococcosis has significantly improved after surgical treatment. Preoperative factors affecting HRQOL of patients with echinococcosis include age, concomitant hypertension, diabetes, heart disease, and the initial lesion location. Postoperative influencing factors include concomitant hypertension and diabetes, as well as postoperative complications.

This study focuses on the cases(mainly characterized by respiratory symptoms such as cough, runny nose, fever, sore throat, and nasal congestion)of an outbreak of upper respiratory tract infections in a kindergarten in Jingyuan County, Baiyin City, Gansu Province, in May 2023. The epidemiological data were collected, and pharyngeal swab specimens were also obtained from the patients. The specimens of the research participants were subjected to respiratory multi-pathogen testing, and the positive specimens were further analyzed by sequencing the second hypervariable region (HRV2) of the G gene of respiratory syncytial virus (RSV) and constructing a phylogenetic tree. A total of 90 patients were collected, with an incidence rate of 22.84% (90/394), and the highest incidence was observed in the junior class group at 29.55%. Among the 17 pharyngeal swab specimens collected, 16 specimens were identified with the A subtype of respiratory syncytial virus. Sequencing analysis confirmed that it was the A subtype ON1 genotype. Based on the aforementioned testing results, it can be concluded that the current epidemic was primarily caused by infection with the A subtype of respiratory syncytial virus. Following the implementation of intervention measures, the epidemic has been effectively controlled.
