OBJECTIVETo analysis the burden of diseases (BOD) and economic burden of disease (EBOD) in Chongqing and provide scientific evidence for effective prevention and control of diseases.

METHODSThe burden of diseases of Chongqing were estimated by use of disability-adjusted life year (DALY) from 2010 to 2013, two-step method was used in the calculation of direct economic burden of diseases. DALY combined with the human capital method were used to measure the indirect economic burden.

RESULTSFrom 2010 to 2013, DALY loss by all causes for the residents in Chongqing were 123.90, 127.01, 123.30 and 125.99 person year per thousand persons, respectively. The diseases mainly included non-communicable diseases, accounting for 83%-87%, followed by injure and infectious diseases. The five leading diseases of BOD in Chongqing were respiratory system disease, circulatory system disease, malignant tumor, accidental death, neuropsychiatric disease, respectively. The total economic burden of diseases was 1 621.34 million yuan RMB in 2013. The direct and indirect economic burden of diseases were 794.42 million yuan RMB and 826.92 million yuan RMB, which could be attributed to circulatory system disease, respiratory system diseases, injury, malignant tumor and muscle bones and connective tissue diseases.

CONCLUSIONRespiratory system disease, circulatory system diseases, malignant tumor, and injury have caused heavy burden both in people's health and economic status in Chongqing. It is necessary to take effective measures to prevent and control these diseases.

Objective: To investigate the impact of COVID-19 on treatment of patients with acute ST segment elevation myocardial infarction(STEMI) undergoing primary percutaneous coronary intervention(PPCI). Methods: This was a multicenter retrospective study. STEMI patients undergoing PPCI from January 1, 2019 to December 31, 2021 were selected, based on the data of Xinnaolvsetongdao App. Clinical data and treatment time indicators, including symptom to first medical contact (S-FMC), symptom to door (StoD), first medical contact to ECG (FMC-ECG), first medical contact to guide wire (FMC-W), door to balloon (DtoB) and total ischemic time in 2019, 2020 and 2021 were compared. STEMI patients aged<60 years were sub-grouped as the young and middle-aged group, and STEMI patients aged≥60 years were sub-grouped as the elderly group. Results: A total of 7 435 (3 305 in 2019, 1 796 in 2020 and 2 334 in 2021) STEMI patients aged (59.6±12.6) years undergoing PPCI were included in this analysis. There were 5 990 males. For STEMI patients with PPCI in 2019, 2020 and 2021, FMC-ECG was 3 (1, 5) min, 3(1, 7) min and 4 (1, 7) min. FMC-W was 73 (56, 87) min, 78 (62, 95) min and 77 (62, 87) min. DtoB was 73 (56, 85) min, 78 (62, 95) min and 77 (62, 86) min. Total ischemic time was 189 (130, 273) min, 196 (138, 295) min and 209 (143, 276) min. FMC-ECG, FMC-W, DtoB and total ischemic time were longer in 2020 and 2021 than in 2019 (all P<0.05). The proportions of patients with FMC-ECG≤10 min (88.4% (1 588/1 796) vs. 92.7% (3 064/3 305), P<0.05), FMC-W≤120 min (87.9% (1 579/1796) vs. 91.7% (3 030/3 305), P<0.05) and DtoB≤90 min (72.3% (1 298/1 796) vs. 80.8% (2 672/3 305), P<0.05) were lower in 2020 than in 2019, whereas no differences were observed in the proportions of patients with FMC-ECG≤10 min (91.3% (2 131/2 334) vs. 92.7% (3 064/3 305), P=0.054), FMC-W≤120 min (92.0% (2 148/2 334) vs. 91.7% (3 030/3 305), P=0.635) and DtoB≤90 min (80.0% (1 867/2 334) vs. 80.8% (2 672/3 305), P=0.424) in 2021 compared with 2019. In the subgroup analysis, the proportions of patients with FMC-ECG≤10 min, FMC-W≤120 min and DtoB≤90 min were lower in the elderly group than in young and middle-aged group in 2019 (all P<0.05). The proportions of patients with FMC-W≤120 min and DtoB≤90 min were lower in the elderly group than in young and middle-aged group in 2021(all P<0.05). No differences were observed in the proportions of patients with FMC-ECG≤10 min, FMC-W≤120 min and DtoB≤90 min between the two group in 2020 (all P>0.05). Conclusions: Affected by the COVID-19, there is a reduction in the number of PPCI cases and treatment delays in STEMI patients, especially in the elderly. After adjusting the treatment strategy and widely applying the Xinnaolvsetongdao APP, the above indicators are significantly improved in 2021 as compared with 2020.

Objective: To assess the incidence and independent risk factors for clinical anastomotic leakage (AL) in patients undergoing anterior resection (AR) or low anterior resection, (LAR) for rectal cancer. Methods: This was a retrospective case-control study of 550 patients with rectal cancer who underwent AR or LAR from April 2007 to March 2017 in Beijing Friendship Hospital, Capital Medical University. The relationship between the incidence of AL and clinicopathological manifestations was analyzed by Chi-squared test and Fisher exact test, and the independent risk factors of AL were analyzed using logistic regression analysis. AL is defined as a defect (including necrosis or abscess formation) of the intestinal wall at the anastomotic site, leading to a communication between the intra- and extra-luminal compartments. AL can be divided into three grades. Grade A anastomotic leakage results in no change in the management of patients, whereas grade B leakage requires active therapeutic intervention but is manageable without re-laparotomy. Grade C anastomotic leakage requires re-laparotomy. Results: AL was noted in 32 (5.8%) of 550 patients with rectal cancer who underwent AR or LAR, including 15 (46.9%) , 4 (12.5%) , and 13 patients (40.6%) with Grades A, B, and C, respectively. Five patients (0.9%, 5/550) died peri-operatively. AL- and non-AL-related deaths occurred in 3 (9.4%, 3/32, all cases were Grade C) and 2 patients (0.4%, 2/518) , respectively, with the two mortality rates being significant difference (P = 0.002) . Chi-squared test or Fisher exact test showed that the incidence of AL was associated with neoadjuvant chemoradiotherapy (P = 0.011) , intraoperative bleeding (≥100 ml) (χ² = 11.980, P = 0.001) , and tension-reducing suture of anastomosis (P = 0.015) . The results of logistic regression analysis showed that the independent risk factors of AL were neoadjuvant chemoradiotherapy (OR = 2.402, 95%CI: 1.004 - 5.749, P = 0.049) , intraoperative bleeding (≥100 ml) (OR = 2.971, 95%CI: 1.269 - 6.957, P = 0.012) and tension-reducing suture of anastomosis (OR = 2.304, 95%CI: 1.008 - 5.263, P = 0.048) . Conclusion The incidence of AL in patients undergoing AR for rectal cancer is 5.8%. The high-risk factors for AL are neoadjuvant chemoradiotherapy, intraoperative bleeding (≥100 ml) , and tension-reducing suture of anastomosis. Patients with these three risk factors have a high risk of AL rate, and a defunctioning stoma should be performed.
