Ob.ective: To compare pelvic floor symptoms at three years following instrumental delivery and cesarean section in the second stage of lab.r and to assess the impact of a sub.equent delivery. Study design: We conducted a prospective cohort study of 393 women with term, singleton, cephalic pregnancies who required instrumental vaginal delivery in theatre or cesarean section at full dilatation b.tween Feb.uary 1999 and Feb.uary 2000. 283 women (72% ) returned postal questionnaires at three years. Results: Urinary incontinence at three years post delivery was greater in the instrumental delivery group as compared to the cesarean section group (10.5% vs 2.0% ), OR 5.37 (95% CI, 1.7, 27.9). There were no significant differences in anorectal or sexual symptoms b.tween the two groups. Pelvic floor symptoms were similar for women delivered b. cesarean section after a failed trial of instrumental delivery compared to immediate cesarean section. A sub.equent delivery did not increase the risk of pelvic floor symptoms at three years in either group. Conclusion: An increased risk of urinary incontinence persists up to three years following instrumental vaginal delivery compared to cesarean section in the second stage of lab.r. However, pelvic floor symptoms are not exacerb.ted b. a sub.equent delivery.

监测新型冠状病毒肺炎(coronavirus disease,COVID)-19大流行期间医院心血管病的表现、诊断和治,以了解COVID-19的间接影响。方法:采用2019年10月28日(COVID-19之前)至2020年5月10日(解除禁闭前)以及2018-2019年同一时间的医院活动数据,对9家英国医院进行回顾性系列横断面研究。研究者分析了流行前和流行期间选定的心血管病的总体数据,并开发了一个在线可视化工具,可以近乎实时地监测变化趋势。结果:在9家医院中,禁闭后(2020年3月23日)的总住院人数和急诊科就诊人数较上年分别下降57.9%(57.1%~58.6%)和52.9%(52.2%~53.5%)。
