BACKGROUND:Maternal anemia is a risk factor for poor pregnancy outcomes and threatens maternal or fetal life. Anemia increases the risk of low birth weight and preterm birth. We aimed to determine the cutoff level of hemoglobin and risk factors for maternal anemia at admission for delivery and investigate the association between maternal anemia and adverse perinatal outcomes in contemporary Taiwanese women. METHODS:About 32,234 women admitted to the Taipei Chang Gung Memorial Hospital from 2001 to 2016 were enrolled in this retrospective observational cohort study. The prevalence of pre-delivery maternal anemia in Taiwan and the maternal demographic and perinatal outcomes associated with maternal anemia was assessed. RESULTS:The 10th and 5th percentile hemoglobin levels of the test cohort (2001-2008, n = 15,602) were 10.8 g/dL and 9.9 g/dL, respectively. In the study cohort (2009-2016, n = 13,026), women who were multiparous, who were aged >34 years, with history of cesarean delivery, and with history of uterine fibroids had higher prevalence of anemia. Anemic women were at increased risk of cesarean delivery, primary cesarean delivery, premature rupture of membranes, early preterm birth <34 weeks, having very low birth weight infants (<1,500 g), having large for gestational age infants, and neonatal intensive care center transfer, but at lower risk of having small for gestational age infants. CONCLUSION:Maternal anemia at delivery is a risk factor for primary cesarean delivery and adverse maternal and neonatal outcomes. Furthermore, we hypothesize that maternal anemia might increase fetoplacental vasculogenesis and angiogenesis as an adaptive response.


背景: 母亲贫血是不良妊娠结局的危险因素,威胁着母亲或胎儿的生命。贫血会增加低出生体重和早产的风险。我们旨在确定入院分娩时血红蛋白的截止水平和母亲贫血的危险因素,并调查当代台湾妇女母亲贫血与围产期不良结局之间的关系。 方法: 本回顾性观察性队列研究入选了 2001年至 2016年入住台北长庚纪念医院的约 32,234 名女性。评估台湾产前孕产妇贫血的患病率以及与孕产妇贫血相关的孕产妇人口统计学和围产结局。 结果: 试验队列 (2001-2008,n = 15,602) 的 10.8 和 9.9 百分位血红蛋白水平分别为 g/dL 和 g/dL。在研究队列 (2009-2016,n = 13,026) 中,年龄> 34 岁,有剖宫产史的经产妇,且有子宫肌瘤病史者贫血患病率较高。贫血妇女剖宫产、初次剖宫产、胎膜早破、早产 <34 周、极低出生体重儿 (<1,500g) 、具有大于胎龄儿,新生儿重症监护中心转移,但具有小于胎龄儿的风险较低。 结论: 产妇分娩时贫血是初次剖宫产分娩及母婴不良结局的危险因素。此外,我们假设母亲贫血可能增加胎儿胎盘血管生成和血管生成作为适应性反应。

METHODS::Maternal lifestyle affects both mother health and pregnancy outcome in humans. Several studies have demonstrated that interventions oriented towards reducing stress and anxiety have positive effects on pregnancy complications such as preeclampsia, excessive gestational weight, gestational diabetes and preterm birth. In this work, we showed that the environmental enrichment (EE), defined as a noninvasive and biological significant stimulus of the sensory pathway combined with voluntary physical activity, prevented preterm birth (PTB) rate in a 41% in an inflammatory mouse model induced by the systemic administration of bacterial lipopolysaccharide (LPS). Furthermore, we found that EE modulates maternal metabolism and produces an anti-inflammatory environment that contributes to pregnancy maintenance. In pregnant mice uterus, EE reduces the expression of TLR4 and CD14 (the LPS receptor and its coactivator protein), preventing the LPS-induced increase in PGE2 and PGF2α release and nitric oxide synthase (NOS) activity. In cervical tissue, EE inhibits cervical ripening events, such as PGE2 release, matrix metalloproteinase (MMP)-9 increased activity and neutrophil recruitment, therefore conserving cervical function. It seems that EE exposure could mimic the stress and anxiety-reducing techniques mentioned above, explaining, at least partially, the beneficial effects of having a healthy lifestyle before and during gestation. Furthermore, we propose that designing an EE protocol for humans could be a noninvasive and preventive therapy for pregnancy complications, averting pre-term birth occurrence and dreaded sequelae that are present in the offspring born to soon.

METHODS:PROBLEM:We aimed to investigate the main causes of recurrent miscarriage (RM) in patients with losses after spontaneous gestation (SG) and after in vitro fertilization (IVF). METHOD OF STUDY:A prospective case-control study was conducted. The eligible patients were women who had experienced two or more consecutive abortions after less than 12 weeks gestation, two consecutive losses after SG or two consecutive losses after IVF. All patients were subjected to the following evaluations: karyotyping of the aborted material, alloimmune and autoimmune marker testing, and acquired and hereditary thrombophilia marker testing. RESULTS:In total, 58 patients were eligible: 32 patients with RM after SG and 26 patients with RM after IVF. The factors associated with RM were genetic (29%), immune (14%), thrombophilic (21%), and thrombophilic and immune (24%), and only 12% of the cases were idiopathic. Comparing the two study groups (SG and IVF), all studied factors were similar, except for a higher ANA positivity observed in the SG group (SG 30.4% versus IVF 5.3%, OR 8.6 (CI 1.1 - 21.1, P 0.048). CONCLUSIONS:Our study identified the possibly factors associated with recurrent miscarriage in 86% of the cases, and these factors appear to be similar in patients with recurrent miscarriage after spontaneous gestation and IVF. This study demonstrates that IVF with PGT-A with euploid embryo transfer could reduce abortions by up to 29%, but other factors needs to be investigated even in patients undergoing in vitro fertilization.

METHODS:OBJECTIVES:To evaluate the impact of pre-operative Music Therapy (MT) on pain in first-trimester abortion under local anaesthesia (ALA). DESIGN:Randomised controlled trial comparing patients undergoing a first-trimester ALA with or without a pre-operative MT session. SETTING:University hospital of Angers from November 2016 to August 2017. POPULATION:Patients who underwent first-trimester abortion under ALA. METHODS:Patients allocated to MT group underwent a pre-operative 20 minutes session of MT. MAIN OUTCOME MEASURES:Pain was assessed using a visual analogue scale (VAS) just before the procedure, during the procedure, at the end of the procedure and upon returning to the ward. RESULTS:159 patients were randomised (80 in MT group, and 79 in the control group). 2 patients were excluded from the control group and 6 from the MT group. Therefore, 77 patients were analysed in the control group and 74 in the MT group. The intensity of pain were similar in both the MT group and the Control group just before the procedure (VAS: 4.0±2.9 vs. 3.6±2.5, p=0.78), during the procedure (VAS: 5.3±2.5 vs. 4.9±2.9, p=0.78), at the end of the procedure (VAS: 2.7±2.4 vs. 2.6±2.4, p=0.43) and upon returning to the ward (VAS:1.8±2.0 vs. 1.5±2.0, p=0.84). The difference in pain between entering the department and returning to the room after the procedure was similar between the MT and Control groups (0.3±2.5 vs. 0.3±2.4 VAS levels difference; p=0.92). CONCLUSION:Music therapy session before an ALA procedure resulted in no improvement in patient perception of pain during a first-trimester abortion.
