OBJECTIVES:There is evidence to suggest that high perceived stress in early pregnancy is associated with increased rates of miscarriage. Our objective was to determine if psychological stressors have an impact on medically assisted reproduction (MAR) cycle outcomes including miscarriage rates. STUDY DESIGN:A survey-based study of women recruited prior to commencing MAR treatment and followed prospectively for treatment outcome (negative/positive pregnancy test, miscarriage) during the study period 2013-2015. The survey focused on perceived stress, emotional well-being, maternal social support and outlook. The women were asked to grade their responses according to a specified scale. RESULTS:320 women responded to the survey (response rate 64 %, 320/498). 290 (90 %, 290/320) women proceeded to MAR of which 58 % (n = 167/290) conceived. Analysis of stressful life events in the preceding 12 months, including job stress or serious financial problems did not reveal significance in terms of conception. A small number had experienced serious illness in the preceding 12 months which demonstrated significance in terms of not achieving pregnancy. Overall, there were high rates of emotional wellbeing, very high rates of maternal support and medium to low levels of perceived stress and this did not differ amongst those who conceived and failed to conceive. The data were further analysed according to livebirth and miscarriage (biochemical pregnancy and miscarriage). Analysis of stressful life events revealed a higher rate of miscarriage amongst those who reported a stressful/demanding job (p < 0.05). A number of women reported non-specified stressful life events and separation/divorce in higher numbers amongst the miscarriage group, reaching statistical significance, however the numbers are small thus limiting interpretation. Psychological factors had no impact on the risk of miscarriage amongst the group. CONCLUSION:This study suggests that stressors do not impact greatly on conception rates from MAR but may negatively impact on miscarriage rates. Job-related stress, in particular, is associated with higher risk of miscarriage. This suggests that there may be a role for stress management in early pregnancy.
目的: 有证据表明，妊娠早期高知觉压力与流产率增加有关。我们的目的是确定心理应激源是否对医学辅助生殖 (MAR) 周期结局包括流产率有影响。 研究设计: 2013-2015 研究期间，对开始 MAR 治疗前招募并前瞻性随访治疗结局 (妊娠试验阴性/阳性，流产) 的女性进行基于调查的研究。调查的重点是知觉压力、情绪幸福感、产妇社会支持和展望。要求女性根据指定的量表对她们的反应进行评分。 结果: 320 名女性对调查做出了回应 (应答率 64%，320/498)。290 例 (90%，290/320) 妇女进入 MAR，其中 58% 例 (n = 167/290) 受孕。分析前 12 个月的应激性生活事件，包括工作压力或严重的财务问题，在受孕方面没有揭示意义。少数在过去的 12 个月里经历了严重的疾病，这表明在没有实现怀孕方面具有重要意义。总体而言，情绪健康率高，母亲支持率非常高，感知压力水平中等至较低，这在受孕和未受孕的人群中没有差异。根据活产和流产 (生化妊娠和流产) 进一步分析数据。压力性生活事件分析显示，报告有压力/要求工作的人流产率较高 (p <0.05)。在流产组中，一些女性报告了非特指的紧张生活事件和分居/离婚的数量较高，达到了统计学意义，但数量较少，从而限制了解释。心理因素对组间流产风险无影响。 结论: 本研究表明压力源对 MAR 的受孕率影响不大，但可能对流产率产生负面影响。尤其是与工作相关的压力与较高的流产风险相关。这表明在妊娠早期可能存在压力管理的作用。
METHODS:BACKGROUND:Controlled ovarian stimulation (COS) has a negative effect on the endometrial receptivity compared with natural menstrual cycle. Whether it's necessary to postpone the first frozen embryo transfer (FET) following a freeze-all strategy in order to avoid any residual effect on endometrial receptivity consequent to COS was inconclusive. OBJECTIVE:The purpose of this retrospective study was to explore whether the delayed FET improve the live birth rate and neonatal outcomes stratified by COS protocols after a freeze-all strategy. METHODS:A total of 4404 patients who underwent the first FET cycle were enrolled in this study between April 2014 to December 2017, and were divided into immediate (within the first menstrual cycle following withdrawal bleeding) or delayed FET (waiting for at least one menstrual cycle and the transferred embryos were cryopreserved for less than 6 months). Furthermore, each group was further divided into two subgroups according to COS protocols, and the pregnancy and neonatal outcomes were analyzed between the immediate and delayed FET following the same COS protocol. RESULTS:When FET cycles following the same COS protocol, there was no significant difference regarding the rates of live birth, implantation, clinical pregnancy, multiple pregnancy, early miscarriage, premature birth and stillbirth between immediate and delayed FET groups. Similarly, no significant differences were found for the mean gestational age, the mean birth weight, and rates of low birth weight and very low birth weight between the immediate and delayed FET groups. The sex ratio (male/female) and the congenital anomalies rate also did not differ significantly between the two FET groups stratified by COS protocols. CONCLUSION:Regardless of COS protocols, FET could be performed immediately after a freeze-all strategy for delaying FET failed to improve reproductive and neonatal outcomes.
METHODS:OBJECTIVE:To evaluate the effect of oral diosmin on the incidence and severity of ovarian hyperstimulation syndrome (OHSS) and explore the value of diosmin in preventing and treating OHSS. METHOD:A retrospective study of women attending a reproductive center in Guangzhou, China, between September and December 2016. The inclusion criterion was previous cancellation of embryo transfer after oocyte retrieval during IVF owing to a high risk of OHSS. The women were divided into two groups depending on whether they received oral diosmin (1000 mg twice daily for 10 days) after oocyte retrieval (diosmin group) or not (control group). Apart from diosmin, both groups underwent the same treatment. Baseline information and data related to OHSS were compared. RESULTS:Overall, 146 women were included: 74 in the diosmin group and 72 in the control group. The incidence of moderate-to-severe OHSS in the diosmin and control groups was 5/74 (6.2%) and 14/72 (13.4%), respectively (P=0.027). The control group included four cases of paracentesis due to ascites; there were no cases of paracentesis or severe OHSS in the diosmin group. CONCLUSION:Oral administration of diosmin effectively reduced both the incidence of moderate-to-severe OHSS and the severity of OHSS among high-risk women.
METHODS::Recurrent implantation failure (RIF) remains a clinical dilemma. Helium-Neon (He-Ne) laser irradiation has recently become more popular under certain clinical conditions. Given the unique therapeutic effects, we were interested in determining whether pretreatment with He-Ne laser irradiation prior to frozen-thawed embryo transfer (FET) would improve the microcirculation and cause the release of growth factors and cytokines, thus improving endometrial receptivity and the clinical pregnancy rates. Patients chose for themselves whether to proceed with (n = 29) or without (n = 31) pretreatment with He-Ne laser irradiation prior to FET. The clinical pregnancy rate (37.9%) and implantation rate (20.3%) were higher in the laser-treatment group than in the control group (35.5% and 15.9%, respectively, p = .844 and .518, respectively). The live birth rate was higher in the laser-treatment group (27.6% vs. 25.8%, respectively, p = .876) and the miscarriage rate was lower in the laser-treatment group (18.2% and 27.3%, respectively, p = .611). No side effects or complications from laser irradiation were encountered in patients who received the laser treatment. We concluded that pretreatment with He-Ne laser prior to FET may be an alternative choice for RIF-affected women; however, additional well-designed prospective studies are necessary to determine the precise clinical value of this treatment.
