[Genital Chlamydia trachomatis infection and associated risk factors in male clients attending sexually transmitted disease clinics in 9 cities in Guangdong province].

Objective: To investigate the prevalence of genital Chlamydia trachomatis (GCT) infection and associated risk factors in male clients attending sexually transmitted disease (STD) clinics in Guangdong and provide integrated intervention strategy for this group. Methods: Convenient sampling was used to recruit participants from April to June in 2015 in Guangdong province. The information about their socio-demographic characteristics and sexual behaviors were collected by using a questionnaire, and blood samples were taken from them to test the antibodies against HIV, syphilis and HCV. First pass urine was taken to test GCT and gonorrhea. Results: A total of 1 749 participants with the average age of 39.53 years were recruited. The majority of them were married (73.87%, 1 292/1 749), residents of Guangdong (92.28%, 1 614/1 749) and in Han ethnic group (99.49%, 1 740/1 749). The positive rates for GCT, HIV, syphilis, HCV, Neisseria gonorrhea, and WBC in urinalysis were 6.06% (106/1 749), 0.46% (8/1 749), 3.43% (60/1 749), 0.45% (7/1 550), 2.74% (48/1 749), 7.89% (138/1 749) respectively. Multivariate analysis showed that risk factors for GCT infection include IDUs (OR=13.98, 95%CI: 3.35-58.38), anal sex with men (OR=3.11, 95%CI: 1.45-6.71), Neisseria gonorrhea positive (OR=9.64, 95% CI: 5.09-18.24), and WBC positive (OR=1.96, 95%CI: 1.08-3.55). Conclusions: This study demonstrated the high prevalence of GCT infection in male clients attending STD clinics in Guangdong. Therefore precision intervention should target this population at high-risk.

Double-balloon catheter versus prostaglandin E2 for cervical ripening and labour induction: a systematic review and meta-analysis of randomised controlled trials.

BACKGROUND: Induction of labour has become an increasingly common procedure. Ripening methods, including mechanical devices and pharmacological agents, improve the success rate of labour induction. OBJECTIVE: To compare the efficacy and safety of the double-balloon catheter with prostaglandin E2 agents used for labour induction. SEARCH STRATEGY: We searched electronic sources from MEDLINE, Embase and Web of Science, the Cochrane Library Database of Systematic Reviews, and ClinicalTrials.gov website. SELECTION CRITERIA: Only randomised controlled trials comparing the PGE2 agents with the double-balloon catheter for cervical ripening and labour induction in women with unfavourable cervices were included in the analysis. DATA COLLECTION AND ANALYSIS: The main outcomes included the vaginal delivery rate within 24 hours and risk of caesarean section. We calculated relative risks and mean differences using fixed- and random-effects models. MAIN RESULTS: Nine studies (1866 patients) were included in this systematic review. Both the double-balloon catheter and PGE2 agents were comparable with regard to rate of caesarean section (RR 0.92; 95% CI 0.79, 1.07), vaginal delivery within 24 hours (RR 0.95; 95% CI 0.78, 1.16) and maternal adverse events, but the risk of excessive uterine activity (RR 10.02; 95% CI 3.99, 25.17) and need for neonatal intensive care unit admissions (RR 1.31; 95% CI 1.01, 1.69) were significantly increased in women who received PGE2 agents. CONCLUSIONS: The double-balloon catheter demonstrated greater safety and cost-effectiveness than PGE2 agents for cervical ripening and labour induction. The efficacy profiles of both methods were similar. TWEETABLE ABSTRACT: Double-balloon catheter versus prostaglandin E2 for cervical ripening and labour induction.
