AIM:To clarify whether the incidence of umbilical cord prolapse (UCP) at delivery is related to the cervical ripening balloon (CRB). METHODS:A postal questionnaire study was conducted in 2018 in institutions providing maternity services across Japan. Questions on the number of deliveries, labor inductions, used CRB and cases of UCP in 2017 were included. Because a similar questionnaire survey was conducted in 2012, the incidence of UCP and frequency of the use of CRB were compared. RESULTS:A total of 1354 answers were assessed (57% of all delivery institutions). The total number of deliveries was 490 279. Of these, 78% were transvaginal; 74 cases of UCP were reported (0.015%), while 13 cases were reported from obstetric facilities never using CRB (0.008%). The incidence of UCP (odds ratio [95% confidence interval]) was 0.036% in the intracervical type (4.3 [1.6-11.3]), 0.091% in the disk-type (11.0 [4.2-29.0]) and 0.067% in the ball-type (8.1 [2.8-22.8]). Frequencies of the use of CRB were 7.3% and 6.6% in the 2012 and 2018 surveys, respectively. The use of the intracervical type increased from 2.8% in the 2012 survey to 3.5% in the 2018 survey, while that of the disk-type and ball-type declined. However, the incidence of UCP was not different between the two surveys regardless of the use of cervical ripening balloons (0.014% vs 0.015% with CRB, 0.005% vs 0.008% without CRB). CONCLUSION:Although the frequency of CRB use significantly declined, the incidence of UCP did not significantly reduce in the last 5 years.


目的: 明确分娩时脐带脱垂 (UCP) 的发生率是否与促宫颈成熟球囊 (CRB) 有关。 方法: 2018 年在日本各地提供生育服务的机构中进行邮寄问卷调查研究。纳入了 2017 年分娩次数、引产、使用 CRB 和 UCP 病例的问题。由于 2012 年进行了类似的问卷调查,比较了 UCP 的发生率和 CRB 的使用频率。 结果: 共评估 1354 个答案 (占所有分娩机构的 57%)。交付总数为 490   279。其中,78% 例经阴道; 报告了 74 例 UCP (0.015%),而 13 例报告来自从未使用 CRB 的产科机构 (0.008%)。宫颈内型 UCP (优势比 [95% 置信区间]) 发生率为 0.036% (4.3 [1.6-11.3]),盘型为 0.091% (11.0 [4.2-29.0]),球型为 0.067% (8.1 [2.8-22.8])。在 7.3% 和 6.6% 次调查中,CRB 的使用频率分别为 2012 和 2018。宫颈内型的使用从 2.8% 调查的 2012 增加到 3.5% 调查的 2018,而盘型和球型的使用下降了。然而,无论使用宫颈成熟球囊,两次调查的 UCP 发生率均无差异 (CRB 为 0.014% vs 0.015%,CRB 为 0.005% vs 0.008%)。 结论: 尽管 CRB 的使用频率显著下降,但 UCP 的发生率在过去 5 年没有显著降低。

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.
