RESUMO
Objective:To investigate outcomes and safety of doxycycline-moxifloxacin sequential regimen in the treatment of Mycoplasma genitalium urethritis/cervicitis. Methods:From June 2019 to December 2020, patients with Mycoplasma genitalium urethritis/cervicitis confirmed by nucleic acid amplification testing were successively recruited at Department of Sexually Transmitted Diseases, Hospital of Dermatology, Chinese Academy of Medical Sciences, and received sequential therapy with oral doxycycline for 7 days followed by oral moxifloxacin for 7 days. Clinical and/or etiological assessment was conducted 2 to 3 weeks after the end of treatment. Fisher′s exact test was used to analyze factors influencing the treatment outcome. Results:Totally, 36 eligible subjects were enrolled, including 30 males and 6 females. Among them, 18 (50%) patients completed post-treatment etiological assessment, which showed that 12 achieved microbiological cure, and treatment failures occurred in 6; another 18 patients achieved clinical cure. The overall response rate to doxycycline-moxifloacin sequential therapy was 83.3% (30/36, 95% confidence interval[ CI]: 70.5%, 96.1%) . The treatment outcome showed no significant association with the patients′ age, gender, marital status, number of sexual partners in the past 1 month, history of sexually transmitted diseases, history of antibiotic use in the past 1 month, or co-infections (all P > 0.05) . Conclusion:The efficacy of doxycycline-moxifloacin sequential regimen is limited in the treatment of Mycoplasma genitalium infections in Nanjing area, and clinicians should be alerted to the possibility of treatment failure in clinical practice.
RESUMO
OBJECTIVE@#To determine the feasibility whether the bovine jugular venous conduit (BJVC) can be fixed with polyepoxy compound (PC).@*METHODS@#Twenty-four BJVCs were divided into 3 groups and fixed with polyepoxy compound (PC group, n = 8), glutaraldehyde (GA group, n = 8), and unfixed group (Control group, n = 8), respectively. The morphologic and mechanical properties of BJVCs in the 3 groups, including thickness, diameter, moisture content, denaturation temperature, tensile strength, elongation at break, and fixation index were measured. The rat subcutaneous model for the assessment of tissue calcification was used. The calcium content in bovine jugular vein patches and valves was determined by flame atomic absorption spectrophotometer.@*RESULTS@#There was no difference in the wall thickness, diameter, and tissue water content between PC and the control group, but significant difference was found between GA and PC groups. The mechanical properties of PC group and GA group were not significantly different, but they were better than those of the control group. GA-fixed BJVC samples showed clear calcification, while PC fixed BJVC were calcified significantly less.@*CONCLUSION@#PC is an effective and suitable choice for the treatment of BJVC since it can effectively preserve the structure and the anti-reflow function of valves in bovine jugular vein and it has better anti-calcification properties.
