Objective:To screen high-risk population of chronic obstructive pulmonary disease (COPD) and to analyze the risk factors in Haicang District of Xiamen City.Methods:A questionnaire survey was conducted from February 2023 to May 2023 among residents who visited or underwent physical examinations at five community health service centers in Haicang District of Xiamen City selected by cluster sampling method. The self-designed general information questionnaire, COPD population screening questionnaire (COPD-PS) and COPD screening questionnaires (COPD-SQ) were applied in the survey. Individuals with COPD-PS scale>5 or COPD-SQ scale>16 were defined as COPD high-risk group. The association of COPD risk with gender, age, smoking, family history of COPD, history of tuberculosis, history of COVID-19 infection, and using coal/woodstove for cooking or heating was analyzed with chi-square test and binary logistic regression analysis.Results:A total of 4 260 questionnaires were distributed and 4 221 valid questionnaires were collected with a recovery rate of 99.6%. Among all respondents there were 1 904 males (45.11%) and 2 317 females (54.89%); and 217 individuals aged 40-<50 (5.14%), 434 aged 50-<60 (10.28%), 2 194 aged 60-<70 (51.98%), 1 302 aged 70-<80 (30.85%) and 74 aged≥80 (1.76%). The results showed that there were 269 respondents (6.4%) scored≥5 on the COPD-PS scale, 534 residents (12.7%) scored≥16 on the COPD-SQ scale, 646 (15.3%) scored≥5 on the COPD-PS scale or≥16 on the COPD-SQ scale. Male gender ( OR=2.592, 95% CI:2.135-3.146), second-hand smoke exposure ( OR=3.763, 95% CI:2.944-4.810), frequently catching cold before the age of 14 ( OR=3.804, 95% CI:2.927-4.944), history of tuberculosis ( OR=2.575, 95% CI:1.224-5.418), hypertension ( OR=1.547, 95% CI:1.277-1.875), and diabetes ( OR=1.791, 95% CI:1.027-3.121) were independently associated with the high-risk of COPD, while the history of COVID-19 ( OR=0.583, 95% CI:0.476-0.714) was a protective factor for COPD risk. Conclusion:Males, exposure to second-hand smoke, frequently catching cold before the age of 14, history of tuberculosis, hypertension, and diabetes will increase the risk of COPD, while the history of COVID-19 is a protective factor.

Objective:To explore the clinical characteristics,treatments,and pregnancy outcomes of pregnant women with malignant ovari-an tumors.Methods:We retrospectively analyzed the clinical data of 11 patients with pregnancies complicated by malignant ovarian tu-mors,including the pathological types,clinical staging,surgical methods,pregnancy outcomes,and follow-up results from January 2012 to December 2022.Results:Among the eleven patients followed up until October 2023,six had primary ovarian tumors and five had metastat-ic ovarian tumors.Among the six primary ovarian tumors,five were epithelial tumors(one in stage ⅠA,two in stage ⅠC,one in stage ⅢA,one in stage ⅡB)and one was a malignant germ cell tumor(stage ⅠA).Four patients were diagnosed at stage Ⅰ:one in early pregnancy who continued the pregnancy and underwent tumor surgery post-delivery,and three in late pregnancy who under went tumor surgery dur-ing cesarean section or postpartum.Two patients were diagnosed at stage Ⅲ:one in early pregnancy with surgery after the termination of pregnancy,and one in late pregnancy with surgery during a cesarean section.Five patients had successful births,including two premature and three full-term births,all alive and healthy.The six patients with primary ovarian tumors were followed up for 18-133 months,and all survived.Five patients had ovarian metastatic tumors,including four cases of Krukenberg tumors and one of a cervical tumor.Two patients were diagnosed in the first trimester and underwent tumor reduction post-abortion.One patient was diagnosed in the second trimester,had to continue the pregnancy,and underwent tumor reduction post-delivery.Two patients were diagnosed in the third trimester:one under-went cesarean section and ovarian tumor resection simultaneously,and the other underwent tumor resection post-delivery.Three patients had successful births,all premature but alive.One of the five patients with ovarian metastatic tumors was lost to follow-up;the remaining four were followed up for 3-22 months,and all deceased.Conclusions:The prognosis for patients with pregnancies complicated by ovarian primary tumors is favorable,whereas the prognosis for patients with pregnancies complicated by ovarian metastatic tumors is poor,neces-sitating greater clinical attention.
