Comparison of Laparoscopic-Assisted Operations and Laparotomy Operations for the Treatment of Hirschsprung Disease: Evidence From a Meta-Analysis

The purpose of this meta-analysis is to compare the relative merits among laparoscopic-assisted operations and laparotomy operations for patients with Hirschsprung disease.PubMed, Web of Science, and Wanfang databases were searched for the related articles. We analyzed dichotomous variables by estimating odds ratios (ORs) with their 95% confidence intervals (CIs) and continuous variables using the weighted mean difference (WMD) with the 95% CI. The random-effects model (REM) was used to combine the results. The outcome measures included operating time (OT), estimated blood loss (EBL), length of hospital stay (LOHS), mean first bowel movement (MFBM), and number of complications.Sixteen articles were included in the meta-analysis. These studies involved a total of 774 patients, 396 of whom underwent laparoscopic-assisted operations and 378 of whom underwent laparotomy operations. The EBL (WMD = −1.48, 95% CI = −1.82, −1.13), LOHS (WMD = −0.67, 95% CI = −0.86, −0.49), MFBM (WMD = −0.83, 95% CI = −1.05, −0.61), and number of complications (OR = 0.60, 95% CI = 0.40, 0.89) were significantly lower in laparoscopic-assisted operations than in laparotomy operations. The OT (WMD = 0.12, 95% CI = −0.05, 0.28) showed no significant differences between laparoscopic-assisted operations and laparotomy operations.Compared with laparotomy operations, laparoscopic-assisted operations are generally safer and more reliable for patients with Hirschsprung disease.     

不同氢溴酸右美沙芬口服固体制剂的溶出度考察

目的：对6个厂家不同氢溴酸右美沙芬口服固体制剂进行体外溶出度考察，比较体外溶出情况，为临床用药提供参考。方法：采用转篮法，转速100 r·min^-1，用高效液相色谱法测定氢溴酸右美沙芬口服固体制剂在0.1 mol·L^-1盐酸溶液中的溶出曲线；以威布尔方程拟合溶出参数T₅₀、T_d、m，并对参数进行方差分析。结果：氢溴酸右美沙普通片、分散片、胶囊以及软胶囊的平均累积溶出度分别为94.3%、101.3%、105.2%、93.4%。溶出参数T₅₀、T_d差异较大，其中T₅₀最大的是最小的13.4倍。结论：氢溴酸右美沙片、分散片、胶囊以及软胶囊体外溶出行为差别大，产品质量存在较大差异。     

40岁以上高龄女性体外受精-胚胎移植妊娠结局分析

目的：探讨40岁以上高龄女性体外受精-胚胎移植（IVF-ET）的妊娠结局，旨在为高龄女性提供生育咨询以及为改善高龄女性个体化辅助生殖治疗结局提供临床依据。方法：选择我院生殖中心2015年1月—2017年12月女方年龄≥40岁且使用自身卵子行体外受精的共2 467个治疗周期资料，对各项临床数据进行回顾性分析。结果：40岁及以上行辅助生殖治疗的患者，随着女性年龄增加获卵数明显减少（40～48岁女性平均获卵数分别为2.97、 2.69、2.17、2.01、1.77、1.61、1.68、1.29和1.00，44～48岁与40～43岁依次组间比较均P＜0.05），尤其是44岁以上女性胚胎发育潜能明显降低（40～48岁囊胚形成率分别为48.90%、43.72%、33.67%、34.29%、24.39%、21.14%、26.32%、16.67%和0%，44～48岁与40～43岁组间依次比较均P＜0.05）。共有518个周期行新鲜胚胎移植，结果显示，随女性年龄增加，临床妊娠率（40～48岁临床妊娠率分别为26.92%、21.15%、20.79%、10.96%、18.87%、11.11%、5.88%、0%和0%，43～48岁与40～42岁组间依次比较均P＜0.05）、种植率（40～48岁种植率分别为23.65%、19.51%、17.70%、8.54%、7.49%、10.81%、5.56%、0%和0%，43～48岁与40～42岁组间依次比较均P＜0.05）和活产率均显著降低（40～46岁活产率分别为18.46%、10.58%、9.90%、5.48%、5.66%、2.78%和5.88%，43～46岁与40～42岁组间依次比较均P＜0.05），43岁以上者结局更差。44岁以上女性自然流产率明显增高（40～45岁流产率分别为31.43%、50.00%、52.38%、50.00%、70.00%和75.00%，44～45岁与40～43岁组间依次比较均P＜0.05）。46岁女性仅1例妊娠并分娩，47岁和48岁女性均无成功妊娠。与抗苗勒管激素（AMH）＞1.0 ng/mL组相比，AMH≤1.0 ng/mL组妊娠率、种植率及活产率均显著下降（27.04% vs. 14.74%，22.99% vs. 13.50%，15.88% vs. 7.37%；均P＜0.05），流产率明显升高（41.27% vs. 50.00%，P＜0.05）。结论：≥40岁高龄女性随年龄增长生育力逐渐降低。40～43岁年龄段女性助孕仍有一定的价值，尤其是卵巢仍有一定储备者（AMH＞1.0 ng/mL），但44岁以上女性原则上不再建议ART助孕，对于46岁以上卵巢功能衰竭的女性强烈建议卵子捐赠或收养。     

Breast Cancer Management During COVID-19 Pandemic in Madrid: Surgical Strategy

BackgroundFrom the first case of SARS-CoV-2 infection in Wuhan (China), the infection spread all around the world causing a pandemic of coronavirus disease-2019 (COVID-19). Spain has been one of the most severely affected countries, and Madrid has reported a high number of cases and deaths. We discuss our strategies for optimal breast cancer management during COVID-19 pandemic.Patients and MethodsThis was a retrospective observational study at Clínico San Carlos Hospital to analyze the management of patients with breast cancer during the pandemic outbreak and the surgical strategy after the pandemic outbreak. We created a practical and dynamic tool based on a “traffic light” system for prioritizing surgical time. Every patient was contacted by telephone with a preoperative COVID-19 protocol. After surgical procedures, patient satisfaction was assessed using the European Organisation for Research and Treatment of Cancer in-patient satisfaction with cancer care questionnaire (EORTC IN-PATSAT32).ResultsPatients with breast cancer actively treated with surgical procedures were put on a waiting list and received systemic therapy. Telemedicine was used to evaluate any side effects and to avoid unnecessary hospital visits. Surgery was only considered after the pandemic outbreak, and then, only those procedures designed to minimize surgical complications and, therefore, reduce hospital stay. We also measured patients’ satisfaction with medical and nursing scales that resulted in a “very good” evaluation tending to “excellent”.ConclusionIt is necessary to adapt management of oncology treatment and surgical strategy to optimize resources during the COVID-19 pandemic. Patients’ perception of care quality and the degree of patients’ satisfaction with health services has potential relevance in the absence of outcome data.
