Objective :
To analyze the screening results of Mycobacterium tuberculosis (MTB) and HIV co-infections in Ningbo City from 2012 to 2020, so as to provide insights into improving the tuberculosis control strategy.
Methods :
Data pertaining to HIV antibody testing among tuberculosis patients, MTB testing among HIV/AIDS patients, treatment of patients with MTB and HIV co-infections and prognosis of anti-tuberculosis therapy were collected from the annual working reports for the management of MTB and HIV co-infections in Ningbo City from 2012 to 2020, and the screening, treatment and prognosis of MTB and HIV co-infections were analyzed.
Results :
A total of 35 385 newly identified tuberculosis patients were reported in Ningbo City from 2012 to 2020, and there were 5 854 cases receiving HIV testing. The annual mean percentage of HIV screening was 17.57%, and the HIV screening rate appeared a tendency towards a rise in Ningbo City from 2012 to 2020 (χ2trend=4 926.309, P<0.001). Eleven patients were tested positive for HIV, with an annual mean HIV positive rate of 0.19%. A total of 26 043 HIV/AIDS patients received MTB screening, with an annual mean screening rate of 95.78%, and the annual screening rate of MTB appeared a tendency towards a rise in Ningbo City from 2012 to 2020 (χ2trend=79.077, P<0.001). A total of 81 tuberculosis patients were detected, with an annual mean detection rate of 0.31%. Among the 92 patients with MTB and HIV co-infections, there were 81 patients receiving anti-tuberculosis and antiviral therapy simultaneously (88.04%), 8 cases receiving anti-tuberculosis therapy alone (8.70%), 2 cases receiving antiviral therapy alone (2.17%) and 1 case without therapy (1.09%). Among the 89 MTB and HIV co-infected patients receiving anti-tuberculosis therapy, 27 cases were cured (30.34%), 53 cases completing the course of treatment (59.55%) and 7 cases died.
Conclusions
The MTB screening rate among HIV/AIDS patients and the percentage of MTB and HIV co-infected patients with successful anti-tuberculosis treatment were high in Ningbo City from 2012 to 2020; however, the HIV screening rate should be improved among tuberculosis patients.

Objective:
To investigate the spatio-temporal distribution characteristics of pulmonary tuberculosis in Ningbo City from 2015 to 2020, so as to provide insights into tuberculosis control.
Methods:
The data of pulmonary tuberculosis cases in Ningbo City from 2015 to 2020 were collected from Tuberculosis Management Information System of China Disease Control and Prevention Information System, and were linked with the geographic information database of Ningbo Planning Design and Research Institute. The software SaTScan version 10.3 was employed for monthly spatio-temporal scanning and cluster analysis of reported pulmonary tuberculosis cases, populations, longitude and latitude in 153 townships of Ningbo City from 2015 to 2020.
Results:
There were one class Ⅰ cluster and two class Ⅱ clusters of pulmonary tuberculosis cases in Ningbo City from 2015 to 2020, and the class Ⅰ cluster was centered in Song'ao Township and covered 37 townships, with aggregation time from January 1, 2015 to December 31, 2017, while class Ⅱ clusters were covered 38 tounships which were centered in Sanqishi Township of Yuyao County, and one township in Hangzhou Bay New Town. The aggregation time was from January to June in 2015 and 2016, from March to August between 2017 and 2019 and between May and October, 2020. The overall reported incidence of pulmonary tuberculosis appeared a tendency towards a decline in each township of Ningbo City from 2015 to 2020; however, the incidence of pulmonary tuberculosis was more than 80 per 100 thousand in Fuming Township of Yinzhou District and Juexi Township of Xiangshan County in 2020.
Conclusions
There were significant spatio-temporal clustering characteristics of pulmonary tuberculosis incidence at a township level in Ningbo City from 2015 to 2020, and the clusters were mainly concentrated in the central and eastern Ningbo City. The reported incidence of pulmonary tuberculosis is high in Fuming Township of Yinzhou District and Juexi Township of Xiangshan County, where targeted regional tuberculosis control strategies should be implemented.

To evaluate the therapeutic effectiveness and safety of a novel gastrointestinal occluder device for gastrobronchial fistula. Data of 5 patients diagnosed as having gastrobronchial fistula who received treatment by a novel gastrointestinal occluder device at the First Affiliated Hospital of Nanjing Medical University from July to August 2020 were retrospectively analyzed. The total operation time, occluding time, intraoperative and postoperative complications, postoperative hospital stay and patients′ satisfaction were reviewed. Regular follow-up was conducted, and the short-term curative effect of occluding was evaluated 1 month after operation.All patients were males with age of 58-69 years. The course of fistula ranged 3-16 months and the diameter ranged 0.3-1.0 cm. All 5 patients achieved technical success with operation time of 38-88 minutes and occluding time of 8-24 minutes. The postoperative hospital stay ranged 3-5 days and the patients′ satisfaction score was 10. No severe complications occurred during or after operation. One month after endoscopic therapy, fistula was completely occluded in 4 patients. One patient died due to severe pulmonary infection and multiple organ failure although the bucking symptom after drinking and eating recovered before. Endoscopic closure of gastrointestinal fistula by means of the novel gastrointestinal occluder device is safe and effective.

Objective:To evaluate the safety and clinical efficacy of the novel double disc-shaped gastrointestinal occluder (hereinafter referred to as occluder) in treatment of refractory tracheoesophageal fistula (TEF).Methods:From July 1, 2020 to January 31, 2021, 10 patients with refractory TEF treated with occluder at Department of Gastroenterology, the First Affiliated Hospital with Nanjing Medical University were collected. The patients′ clinical data such as gender, age, body mass index and fistula diameter were recorded. The success rate of operation, intraoperative and postoperative complications, operation time, postoperative hospital stay, efficacy of fistula closure and postoperative recovery were analyzed. The Karnofsky score and body mass index of patients 1 month and 3 months after operation were compared with those before operation for curative effect evaluation. Paired t test was used for statistical analysis. Results:Among the 10 TEF patients, there were 7 males and 3 females, the median age was 64.5 years old (ranged from 49.0 to 78.0 years old), the body mass index was (18.0±2.5) kg/m 2 and the diameter of the fistula was (1.2±0.6) cm. Occluder placement was successful in all patients. The operation time was (17.6±7.8) min (ranged from 7.0 to 30.0 min). Two cases had little bleeding during the operation, and there was no bleeding after the operation. The postoperative hospital stay was (5.9±4.0) d (ranged from 1.0 to 12.0 d). Among the 10 TEF patients, fistula of 5 patients were completely blocked, 4 cases were partially blocked and 1 case was ineffectively blocked, the effective rate of blocking was 9/10. One month follow-up after operation showed that the symptoms of choking and coughing during eating were significantly improved in 9 patients, and the symptoms of choking and coughing during eating were significantly improved in 1 patient after waist diameter of 12 mm occluder was replaced with the occluder of 15 mm. The 3-month follow-up after operation showed that the occluders were in the right place in 8 patients, the occluder was displaced in 1 patient and the occluder was removed and treated with enteral nutrition. One patient died due to the recurrence of esophageal cancer. The Karnofsky score of TEF patients 3 months after operation and the body mass index of TEF patients 1 month and 3 months after operation were higher than those before operation (70.0±34.0 vs. 46.0±10.7, (19.32±2.59) and (19.73±2.92) kg/m 2 vs. (18.03±2.50) kg/m 2), and the differences were statistically significant ( t=-3.09, -2.37 and -2.82, all P<0.05). Conclusions:Gastrointestinal occluder is safe and effective in the treatment of refractory TEF.
