Abstract
In this guideline, recurrent miscarriage has been defined as three or more first trimester miscarriages. However, clinicians are encouraged to use their clinical discretion to recommend extensive evaluation after two first trimester miscarriages, if there is a suspicion that the miscarriages are of pathological and not of sporadic nature. Women with recurrent miscarriage should be offered testing for acquired thrombophilia, particularly for lupus anticoagulant and anticardiolipin antibodies, prior to pregnancy. [Grade C] Women with second trimester miscarriage may be offered testing for Factor V Leiden, prothrombin gene mutation and protein S deficiency, ideally within a research context. [Grade C] Inherited thrombophilias have a weak association with recurrent miscarriage. Routine testing for protein C, antithrombin deficiency and methylenetetrahydrofolate reductase mutation is not recommended. [Grade C] Cytogenetic analysis should be offered on pregnancy tissue of the third and subsequent miscarriage(s) and in any second trimester miscarriage. [Grade D] Parental peripheral blood karyotyping should be offered for couples in whom testing of pregnancy tissue reports an unbalanced structural chromosomal abnormality [Grade D] or there is unsuccessful or no pregnancy tissue available for testing. [GPP] Women with recurrent miscarriage should be offered assessment for congenital uterine anomalies, ideally with 3D ultrasound. [Grade B] Women with recurrent miscarriage should be offered thyroid function tests and assessment for thyroid peroxidase (TPO) antibodies. [Grade C] Women with recurrent miscarriage should not be routinely offered immunological screening (such as HLA, cytokine and natural killer cell tests), infection screening or sperm DNA testing outside a research context. [Grade C] Women with recurrent miscarriage should be advised to maintain a BMI between 19 and 25 kg/m2 , smoking cessation, limit alcohol consumption and limit caffeine to less than 200 mg/day. [Grade D] For women diagnosed with antiphospholipid syndrome, aspirin and heparin should be offered from a positive test until at least 34 weeks of gestation, following discussion of potential benefits versus risks. [Grade B] Aspirin and/or heparin should not be given to women with unexplained recurrent miscarriage. [Grade B] There are currently insufficient data to support the routine use of PGT-A for couples with unexplained recurrent miscarriage, while the treatment may carry a significant cost and potential risk. [Grade C] Resection of a uterine septum should be considered for women with recurrent first or second trimester miscarriage, ideally within an appropriate audit or research context. [Grade C] Thyroxine supplementation is not routinely recommended for euthyroid women with TPO who have a history of miscarriage. [Grade A] Progestogen supplementation should be considered in women with recurrent miscarriage who present with bleeding in early pregnancy (for example 400 mg micronised vaginal progesterone twice daily at the time of bleeding until 16 weeks of gestation). [Grade B] Women with unexplained recurrent miscarriage should be offered supportive care, ideally in the setting of a dedicated recurrent miscarriage clinic. [Grade C].

Abstract
Objective PCOS is a syndrome of ovarian dysfunction associated with recurrent pregnancy loss. Several correlating factors have been investigated that influence the risk of pregnancy loss in PCOS. However, uncertainty remains about their contribution to pregnancy loss and prognosis. This review of literature aims to identify what is known and what requires further investigation on the relationship between PCOS and recurrent pregnancy loss, to guide future research and optimize medical guidance throughout pregnancy. Study design a review of literature was performed on several search engines using the following terms; polycystic ovarian syndrome, PCOS, recurrent pregnancy loss, recurrent miscarriage, RPL, aborted fetus, abortus provocatus, miscarriage and habitual abortion. Results 37 articles were included; 3 systematic reviews, 1 meta-analysis, 2 randomized controlled trials, 6 prospective cohort studies, 22 case-control studies and 3 case series. The main objectives investigated by studies were pregnancy complications, pregnancy loss and live birth in the PCOS population. Conclusion Studies that investigated the relationship between PCOS and recurrent pregnancy loss are few and inconsistent and warrant further research. Factors apt for further investigation include the extent to which PCOS phenotypes, BMI, obesity, insulin resistance, hyperandrogenemia, SHBG, hs-CRP, CTRP6, adiponectin, plasma leptin, homocysteine, AMH and thrombophilia contribute to further risk of miscarriage. Other factors requiring further exploration in relation to risk for miscarriage in PCOS patient with RPL include sOB-R, PAI-Fx and the Factor-V-Leiden mutations.

'You're never pregnant in the same way again': prior early pregnancy loss influences need for health care and support in subsequent pregnancy. Hum Reprod Open 2023; 2023:hoad032. [PMID: 37577178 PMCID: PMC10412407 DOI: 10.1093/hropen/hoad032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2023] [Revised: 06/14/2023] [Indexed: 08/15/2023] Open
Abstract
STUDY QUESTION What are couples' needs for health care and support in a subsequent pregnancy after prior early pregnancy loss (PL) and how do needs change across the pregnancy? SUMMARY ANSWER Couples described unmet needs for pregnancy care in the first 20 weeks of pregnancy and were more satisfied with the care provided during the remainder of the pregnancy. WHAT IS KNOWN ALREADY Despite early PL being common (∼25% of pregnancies), there is a paucity of research to guide practice to optimize treatment and support future pregnancies. There has been low priority for the issue in research and a pervasive acceptance that couples should 'just try again' after experiencing PL. Women with prior PL report increased anxiety during the first trimester of pregnancy compared to those without previous PL. No longitudinal studies explore what couples' needs are throughout the pregnancy and how these needs shift across time. STUDY DESIGN SIZE DURATION This was a qualitative longitudinal dyadic (joint) interview study. In total, 15 couples who were pregnant after a prior PL were interviewed four times over their pregnancy. Couples were recruited from the Copenhagen Pregnancy Loss Cohort Research Programme. Interviews were held in person at the hospital or university, or online. Interviews ranged from 20 to 91 min (mean = 54 min). PARTICIPANTS/MATERIALS SETTING METHODS Inclusion criteria included couples with one to two prior early PL(s) who self-reported a new pregnancy and were willing to be interviewed together and in English. Couples were interviewed four times: after a positive pregnancy test and once in each trimester. Interviews were transcribed and data were analysed using thematic analysis to compare and contrast needs of the couples at each of the four time periods in the pregnancy and across the entire pregnancy. One same-sex couple and 14 heterosexual couples participated. MAIN RESULTS AND THE ROLE OF CHANCE Couples' needs were categorized into two main longitudinal themes across the pregnancy, divided by the 20-week scan. Within each longitudinal theme, there were two themes to represent each time period. In the longitudinal theme 'The first 20 weeks: a 'scary' gap in care' there were two themes: Positive pregnancy test: 'Tell them it's not the same pregnancy' and First trimester: 'We craved that someone was taking care of us'. The standard pregnancy care offered in the public healthcare system in Denmark includes a scan at 12 and 20 weeks. While all couples wished for additional access to scans and monitoring of the foetus in early pregnancy to provide reassurance and detect problems early, they described considerable variation in the referrals and care they were offered. Both partners expressed a high degree of worry and anxiety about the pregnancy, with pregnant women in particular describing 'surviv[ing] from scan to scan' in the early weeks. Couples took scans wherever offered or paid for comfort scans, but this resulted in fragmented care. Instead, they wished for continuity in care, and acknowledgement and sensitivity that a pregnancy after PL is not the same as a first pregnancy. In the longitudinal theme 'The second 20 weeks: Safety in the care system' there were two themes: Second trimester: 'I think we are in good hands' and Third trimester: 'It's more of a 'nice to know' everything is OK than a 'need to know'. Couples reported their distress was lower and overall needs for care were met during this time. They expressed general satisfaction with regular or extended antenatal support although, as in the first 20 weeks, additional acknowledgement and sensitivity regarding their history of PL was desired. Couples said they felt more secure given that they had access to a 24-hour telephone support by midwife/nurse if they had any concerns or questions. LIMITATIONS REASONS FOR CAUTION Participants were self-selected from an ongoing cohort study of patients presenting at hospital with PL. Single women were not included in the study. This study was limited to data collection in Denmark; however, other countries with public healthcare systems may have similar offerings with regard to their provision of antenatal care, care provided in recurrent pregnancy loss (RPL) clinics and the availability of private scans. WIDER IMPLICATIONS OF THE FINDINGS The findings underscore that an early PL creates an increased need for monitoring and care in a subsequent pregnancy. This study highlights a gap in pregnancy care for those with a history of PL given that their need for monitoring and support is high in the early weeks of a new pregnancy before they have access to antenatal care, and before they have had multiple PLs and can be referred to the RPL unit.

Mitchell JM, Cullen S, McEvoy A, Crosby D, Allen C. Can Anti-Müllerian Hormone levels predict future pregnancy outcomes in recurrent pregnancy loss? Eur J Obstet Gynecol Reprod Biol 2023; 284:20-23. [PMID: 36924658 DOI: 10.1016/j.ejogrb.2023.03.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2023] [Revised: 03/02/2023] [Accepted: 03/08/2023] [Indexed: 03/17/2023]
Abstract
OBJECTIVE Serum Anti-Müllerian Hormone (AMH) levels have been shown to be lower among women who have experienced recurrent pregnancy loss (RPL) compared with the general population. However, it is unclear whether it can predict livebirth. This study aims to determine whether AMH can predict the likelihood of a livebirth in women with RPL. STUDY DESIGN Prospective analysis of a consecutive cohort of women undergoing investigation for RPL in a tertiary referral centre over a seven year period (August 2014 -December 2021). Analysis was performed using descriptive statistics, chi-square models and logistic regression models adjusting for maternal age and previous livebirth. Exclusion criteria for the regression analysis included abnormal parental karyotype and abnormal pelvic ultrasound scan. Pregnancy outcome was defined as livebirth or further pregnancy loss. RESULTS There were 488 women who underwent investigation of RPL during the study period. Of these, 65.2% (n = 318) conceived following attendance at the clinic. The majority of these women (69.4%, n = 221) proceeded to have a livebirth. There were no differences in median AMH levels between the livebirth group and the further pregnancy loss group (11 pmol/L vs 9 pmol/L respectively (p = 0.083). AMH did not affect clinical pregnancy rates (p = 0.77, 95% CI = 0.99 [0.98, 1.01]) or pregnancy outcome (p = 0.30, 95% CI = 1.01 [0.99, 1.04]). Abnormal pelvic ultrasonography (p = 0.04) and an abnormal parental karyotype (p = 0.04) were associated with an increased likelihood of a subsequent pregnancy loss. CONCLUSION Although AMH levels may have some utility in counselling of some couples with RPL, these contemporaneous data indicate that low AMH does not negatively influence subsequent pregnancy outcome in women with recurrent pregnancy loss.

Self-Reported Depression among Chinese Women with Recurrent Pregnancy Loss: Focusing on Associated Risk Factors. J Clin Med 2022; 11:jcm11247474. [PMID: 36556090 PMCID: PMC9785000 DOI: 10.3390/jcm11247474] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2022] [Revised: 11/30/2022] [Accepted: 12/12/2022] [Indexed: 12/23/2022] Open
Abstract
(1) Background: To investigate whether women suffering from recurrent pregnancy loss (RPL) have a higher prevalence of self-reported depression than healthy controls and to assess the associated risk factors for RPL women self-reporting the symptom of depression. (2) Methods: A cross-sectional study investigating 247 women with histories of RPL and 193 healthy women was performed in Southwest China. The Zung Self-Rating Depression Scale (SDS) was used to measure self-reported depression, and the prevalence of self-reported depression was compared between the two groups. Sociodemographic data for the two groups and clinical information for the RPL group were collected by questionnaires. (3) Results: The prevalence of self-reported depression was higher in the RPL group than in the control group (45.3% vs. 30.1%, p < 0.01). Subgroup analyses indicated that the statistical difference in the prevalence of self-reported depression was significant in the subgroups of women in the first trimester of gestation, age ≥ 36 years, BMI ≥ 18.5 kg/m2, working hours ≤ 8 h/day, university and higher education, and urban residence. Multivariable logistic analysis indicated that age ≥ 36 years, >2 times of spontaneous miscarriages, and no history of live birth were independent risk factors for RPL women self-reporting depression. (4) Conclusions: A higher prevalence of self-reported depression was observed in RPL patients than in healthy women. The psychological status for RPL patients with age ≥ 36 years, >2 times of spontaneous miscarriages, or without a history of a live birth needs to be further addressed.

Abstract
Background: Pregnancy loss is the most common complication of pregnancy and understanding the needs of individuals experiencing pregnancy loss will help the medical team provide patient-centered care. Few studies address differences in needs of individuals regarding timing of pregnancy losses and number of losses. Methods: An anonymous nine-question survey assessing the experience and immediate needs of individuals who have had pregnancy loss. Results: The survey response was high (79%; 793/1000). 75.8% of the respondents experienced first trimester losses, and 55.0% experienced more than one pregnancy loss. Respondents with three or more losses were more likely to see a reproductive endocrinologist compared to those experiencing one loss (15.7% vs. 6.4%, p < 0.01). The highest-ranked need among all respondents (45.5%) was understanding why their pregnancy loss occurred followed by family support (26.8%). However, those who had more than three losses or first trimester losses ranked preventing a future pregnancy loss over family support. Respondents with three or more losses more frequently desired a referral to a pregnancy loss team (37.5% vs. 79.7%, p < 0.001). A qualitative analysis of respondents' comments on how to provide patient-centered care revealed five major themes; the most frequently mentioned theme was staff preparedness, competence, and availability. Conclusion: Our survey highlights the overwhelming importance to individuals who have had pregnancy loss of finding a cause for their loss, regardless of gestational age/multiple losses. Referral to a dedicated pregnancy loss provider/team is highly desired. Finally, patients value sensitivity, compassion, and emotional support from their physicians and their staff.

Abstract
Background Recurrent miscarriage (RM) affects 1%-5% of the reproductive age population. Given increasing calls for dedicated recurrent miscarriage clinics (RMC), decision makers will require data on the resultant budgetary implications. The aim of this study was to identify the potential costs to the Irish healthcare system of implementing a best practice RMC model of care. Methods A ‘best practice’ RMC was developed as part of the RE:CURRENT Project. A micro-costing approach was employed by identifying, measuring, and valuing resource usage by unit costs for the RMC for ≥2 consecutive losses. Per patient costs were estimated using two care pathway scenarios: typical and complex. Per patient costs were extrapolated, using population data and published prevalence rates for RM, to estimate the total cost to the Irish health system. A sensitivity analysis was also performed. Results The cost for a RM patient who has another pregnancy after receiving investigations, treatment and reassurance scans ranges between €1,634 (typical) and €4,818 (complex). For a RM patient who does not conceive again, costs range from €1,384 (typical) to €4,318 (complex). Using population estimates for ≥2 losses, the total cost to the Irish health service ranges from €20,336,229 (complex) to €61,927,630 (typical) for those who progress to pregnancy, and from €7,789,437 (complex) to €22,480,630 (typical) for those who do not progress to another pregnancy. Together, the total cost of the proposed best practice RMC is €112,533,926 with an average cost per patient €1,871. Conclusions This study advocates for a new model of care for RMCs in Ireland and provides a set of cost estimates at the patient and healthcare system level. While future studies should explicitly consider the cost effectiveness of this or similar models of care, this analysis provides a valuable first step in providing a detailed breakdown of the associated costs and budget implications.

Abstract
Recurrent implantation failure (RIF) is defined as the failed pregnancy after good embryo transfer over 3 cycles during in vitro fertilization (IVF).The human endometrium plays a vital role in providing the site for embryo implantation, with several factors implicated in unsatisfactory endometrial receptivity in RIF. Our present results revealed that women with pregnancy loss or infertility have a higher serum epinephrine level, indicating a potential correlation between psychological stress and pregnancy failure. RNA-sequencing of the tissues collected at the endometrial receptive phase in normal and RIF women showed that stress hormones could affect the functional status of endometrial receptivity. Subsequent analysis revealed that the epinephrine signaling acts as an important regulator of endometrial receptivity through the PI3K-AKT and FOXO1 signaling pathways. We also found that patients with RIF show attenuated expression of the alpha-2C-adrenergic receptor (ADRA2C) and that its down regulation induced by high level epinephrine could inhibit the decidualization. Early pregnant mice treated with stress showed high serum epinephrine levels, defective uterine adrenergic receptor expression, and low pregnancy rates. Altogether, our findings indicate that mental stress during early pregnancy can alter the functional status of endometrial receptivity.

Plasma level of mannose-binding lectin is associated with the risk of recurrent pregnancy loss but not pregnancy outcome after the diagnosis. Hum Reprod Open 2022; 2022:hoac024. [PMID: 35747402 PMCID: PMC9211012 DOI: 10.1093/hropen/hoac024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2022] [Revised: 05/27/2022] [Indexed: 12/08/2022] Open
Abstract
STUDY QUESTION Are low or high plasma mannose-binding lectin (p-MBL) levels associated with recurrent pregnancy loss (RPL) and the reproductive and perinatal outcomes before and after RPL? SUMMARY ANSWER The prevalence of low p-MBL levels was significantly higher in RPL patients, while high levels were significantly less prevalent. No association was found between p-MBL level and reproductive and perinatal outcomes before and after RPL. WHAT IS KNOWN ALREADY Mannose-binding lectin (MBL) is an important component in the innate immune system. Low p-MBL levels have been associated with RPL, while the correlation with high levels has been poorly studied. Adverse perinatal outcomes are generally more frequent among RPL patients, but reports concerning the association between maternal p-MBL levels and perinatal outcomes, including birth weight (BW) and gestational age (GA), are conflicting. STUDY DESIGN, SIZE, DURATION This study was a combined cross-sectional and cohort study of 267 RPL patients admitted to the RPL Center of Western Denmark between January 2016 and March 2020. RPL patients were followed until birth of a liveborn child or until end of follow-up, March 2021. A sample of 185 healthy female blood donors of reproductive age was used as a MBL reference group. PARTICIPANTS/MATERIALS, SETTING, METHODS All RPL patients had ≥3 consecutive pregnancy losses, a regular menstrual cycle and no known significant chromosomal or uterine malformations. At the first consultation, routine blood samples including p-MBL measurement and detailed obstetrical and perinatal information were collected. p-MBL levels in RPL patients were compared to the MBL reference group. A logistic regression analysis adjusted for relevant confounders assessed the association between low p-MBL levels and an unsuccessful reproductive outcome in RPL patients in first pregnancy after admission. Perinatal outcomes before and after RPL were compared between RPL subgroups according to low (≤500 µg/l), intermediate (501–3000 µg/l) and high (>3000 µg/l) p-MBL levels. MAIN RESULTS AND THE ROLE OF CHANCE Significantly more RPL patients had low p-MBL levels (prevalence proportion ratio (PPR): 1.79, 95% CI: 1.34–2.38) and fewer had high p-MBL levels (PPR: 0.56, 95% CI: 0.40–0.79) compared to the reference group, while the prevalence of intermediate p-MBL level was not different between the groups (PPR: 0.86, 95% CI: 0.69–1.08). In the prospective study, low p-MBL level was not a significant risk factor for a pregnancy loss in the first pregnancy after admission after adjustment for age, BMI and smoking. Neither before nor after the RPL diagnosis were maternal p-MBL levels significantly associated with BW or GA. LIMITATIONS, REASONS FOR CAUTION Only 161 (60.3%) patients had given birth after RPL during the follow-up period, which limited the possibility to detect clear associations between p-MBL levels and perinatal outcomes after RPL. WIDER IMPLICATIONS OF THE FINDINGS In agreement with several previous studies, low p-MBL levels are strongly associated with RPL, while this study for the first time documents that high levels may play a protective role, which suggests a causal relationship. We suggest that larger prospective studies evaluate the association between p-MBL levels and RPL prognosis. STUDY FUNDING/COMPETING INTEREST(S) No external funding was received.

BMC Public Health 2022; 22:894. [PMID: 35513825 PMCID: PMC9069749 DOI: 10.1186/s12889-022-13299-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2021] [Accepted: 04/20/2022] [Indexed: 12/04/2022] Open
Abstract
Background Significant rates of anxiety, depressive symptoms, and low quality of life (QoL) have been found among pregnant women in developed countries. These psychosocial disturbances have not been adequately assessed during pregnancy in many developing countries. Methods Women were recruited in their first trimester of pregnancy (< 13 weeks; n = 116) and followed through to their 2nd (n = 71) and 3rd (n = 71) trimesters. Questionnaires were used to collect data on anxiety symptoms (Beck Anxiety Inventory; BAI), depressive symptoms (Center for Epidemiological Studies-Depression Inventory; CES-D), and quality of life (RAND SF-36; QoL). Psychometric analyses were used to determine the reliability of the questionnaires in this context. The proportion of pregnant women with psychosocial disturbances at each trimester was determined. Repeated measures ANOVA were used to examine changes in psychosocial outcomes over time; and generalized estimating equation to determine if gestational age predicted the psychosocial outcomes whilst controlling for sociodemographic variables. Results Participants were aged 27.1 ± 5.2 years, on average. Psychometric analyses revealed a 4-factor solution for BAI (18 items), 1-factor solution for CES-D (13 items) and 4-factor solution for RAND SF-36 (26 items). The prevalence estimate of psychosocial disturbances was 34%, 10%, 2% (anxiety), 49%, 31%, 34% (depressive symptoms), and 46%, 37%, 59% (low QoL) for 1st, 2nd and 3rd trimesters, respectively. Gestational age and food insecurity were significant predictors of depressive symptoms, anxiety symptoms and QoL. Conclusions In this population of Ghanaian women, the levels of depressive symptoms and low QoL observed across pregnancy should be recognized as major public health problems and efforts to address these should be put in place. Addressing food insecurity may be a major step to solve not only the physical needs of the pregnant woman but also the psychological needs.

Abstract
Background International guidelines recommend to offer supportive care during a next pregnancy to couples affected by recurrent pregnancy loss (RPL). In previous research, several options for supportive care have been identified and women’s preferences have been quantified. Although it is known that RPL impacts the mental health of both partners, male preferences for supportive care have hardly been explored. Methods A cross-sectional study was conducted in couples who visited a specialized RPL clinic in the Netherlands between November 2018 and December 2019. Both members of the couples received a questionnaire that quantified their preferences for supportive care in a next pregnancy and they were asked to complete this independently from each other. Preferences for each supportive care option were analysed on a group level (by gender) and on a couple level, by comparing preferences of both partners. Results Ninety-two questionnaires (completed by 46 couples) were analysed. The overall need for supportive care indicated on a scale from 1 to 10 was 6.8 for men and 7.9 for women (P = 0.002). Both genders preferred to regularly see the same doctor with knowledge of their obstetric history, to make a plan for the first trimester and to have frequent ultrasound examinations. A lower proportion of men preferred a doctor that shows understanding (80% of men vs. 100% of women, P = 0.004) and a doctor that informs on wellbeing (72% vs. 100%, P = ≤0.000). Fewer men preferred support from friends (48% vs. 74%, P = 0.017). Thirty-seven percent of men requested more involvement of the male partner at the outpatient clinic, compared to 70% of women (P = 0.007). In 28% of couples, partners had opposing preferences regarding peer support. Conclusions While both women and men affected by RPL are in need of supportive care, their preferences may differ. Current supportive care services may not entirely address the needs of men. Health care professionals should focus on both partners and development of novel supportive care programs with specific attention for men should be considered.

Abstract
Although many potential causes have been established for recurrent implantation failure (RIF) and recurrent miscarriage (RM), about 50% of these remain idiopathic. Scientific research is focused on immunological risk factors. In the present study, we aim to evaluate live birth rates after immunization with paternal lymphocytes (lymphocyte immunotherapy (LIT)). This retrospective study consisted of 148 couples with a history of RM and/or RIF. The women underwent immunization with lymphocytes of their respective partners from November 2017 to August 2019. Fifty-five patients (43%) had live births. Stratified by indication (RM, RIF, combined), live birth rates in the RM and the combined group were significantly higher than that in the RIF group (53%, 59% and 33%, respectively, p = 0.02). The difference was especially noticeable during the first 90 days after immunization (conception rate leading to live births: 31%, 23% and 8% for RM, the combined group and RIF, respectively; p = 0.005), while there was no difference between groups during the later follow-up. LIT was associated with high live birth rates, especially in women with recurrent miscarriage. In view of the limited data from randomized studies, LIT cannot be recommended as routine therapy. However, it may be considered in individual cases.

Abstract
Background: Recurrent miscarriage (RM) and infertility are independently associated with adverse pregnancy outcomes, in addition to psychological sequelae. Experiencing pregnancy loss alongside infertility is particularly difficult. International guidance regarding RM is conflicting, and applicability to women with infertility is undetermined. The aim of this study was to: (i) establish if women/couples with a history of infertility are recognised in the literature on the investigation and management of RM, and (ii) determine if the specific needs of women/couples experiencing RM and infertility are ascertained and incorporated into clinical management strategies. Methods: We examined the wide-ranging literature to ascertain what gaps existed. Studies were retrieved through searches of PubMed and Google Scholar up to 21 January 2021 using appropriate controlled vocabulary and combinations of key words. No language or study design restrictions were applied. Results: While women/couples experiencing RM after infertility appear in studies evaluating investigations and proposed treatments, high-quality studies are lacking. Furthermore, they are largely excluded from international clinical guidance and qualitative research. Conclusions: The experiences of women/couples with RM and infertility and their specific care needs within maternity and fertility services are underexplored. It is unclear from current RM guidelines how best to manage and support this complex cohort. Women/couples with infertility and RM are underserved in the literature and in clinical guidance. Further robust studies are warranted to examine pregnancy outcomes, investigations and treatments currently used. Qualitative research is also required to identify their medical and psychological needs to better support this vulnerable group.

Abstract
RESEARCH QUESTION Can participating in a tailored 7-week meditation and mindfulness programme with additional standard supportive care versus standard supportive care only reduce perceived stress for women with recurrent pregnancy loss (RPL)? DESIGN A two-armed randomized controlled trial (RCT) with 12-month follow-up. In total 76 patients were enrolled and randomly assigned to either standard supportive care or to a 7-week meditation and mindfulness programme led by an instructor in addition to standard supportive care. RESULTS At intervention completion (after 7 weeks), perceived stress decreased significantly both in the intervention group (P = 0.001) and in the control group (P = 0.006). The decrease in perceived stress in the intervention group was significantly larger (P = 0.027) compared with the control group. At the 12-month follow-up perceived stress was still significantly decreased in both groups compared with baseline (P < 0.0001 in the intervention group and P = 0.002 in the control group). CONCLUSION This first RCT of a tailored meditation and mindfulness intervention for women with RPL documents that a 7-week daily at-home meditation and mindfulness programme combined with group sessions reduced perceived stress significantly more than a standard supportive care programme. Future studies should address the most effective format and the 'dose' needed for an impact on perceived stress levels.

Abstract
Miscarriage is generally defined as the loss of a pregnancy before viability. An estimated 23 million miscarriages occur every year worldwide, translating to 44 pregnancy losses each minute. The pooled risk of miscarriage is 15·3% (95% CI 12·5-18·7%) of all recognised pregnancies. The population prevalence of women who have had one miscarriage is 10·8% (10·3-11·4%), two miscarriages is 1·9% (1·8-2·1%), and three or more miscarriages is 0·7% (0·5-0·8%). Risk factors for miscarriage include very young or older female age (younger than 20 years and older than 35 years), older male age (older than 40 years), very low or very high body-mass index, Black ethnicity, previous miscarriages, smoking, alcohol, stress, working night shifts, air pollution, and exposure to pesticides. The consequences of miscarriage are both physical, such as bleeding or infection, and psychological. Psychological consequences include increases in the risk of anxiety, depression, post-traumatic stress disorder, and suicide. Miscarriage, and especially recurrent miscarriage, is also a sentinel risk marker for obstetric complications, including preterm birth, fetal growth restriction, placental abruption, and stillbirth in future pregnancies, and a predictor of longer-term health problems, such as cardiovascular disease and venous thromboembolism. The costs of miscarriage affect individuals, health-care systems, and society. The short-term national economic cost of miscarriage is estimated to be £471 million per year in the UK. As recurrent miscarriage is a sentinel marker for various obstetric risks in future pregnancies, women should receive care in preconception and obstetric clinics specialising in patients at high risk. As psychological morbidity is common after pregnancy loss, effective screening instruments and treatment options for mental health consequences of miscarriage need to be available. We recommend that miscarriage data are gathered and reported to facilitate comparison of rates among countries, to accelerate research, and to improve patient care and policy development.

Abstract
BACKGROUND Miscarriage occurs in 10-15% of pregnancies and recurrent pregnancy loss (RPL) occurs in 1% of couples hoping for a child. Various risk factors, such as thrombophilia, uterine malformation, and embryonic chromosomal aberration cause RPL. We hypothesized that antithrombotic therapy for RPL patients with thrombophilia would reduce miscarriage due to thrombophilia, which would reduce the total miscarriages and result in a relative increase in miscarriage due to embryonic chromosomal aberrations. In this study, we investigated the incidence of chromosomal aberrations in products of conception in RPL patients with and without antithrombotic therapy. METHODS We performed a single-center, retrospective review of cases diagnosed as miscarriage with embryo chromosome analysis between July 1, 2000, and May 31, 2019. Rates of chromosomal aberration were compared between RPL patients with and without thrombophilia or antithrombotic therapy. RESULTS One hundred and-ninety RPL cases were analyzed. The average age was 37.4 ± 4.3 years, and the average number of previous pregnancy losses was 2.2 ± 1.1. The overall chromosomal aberration rate was 67.4% (128/190). There was no difference in the chromosomal aberration rate between the factors for RPL, with or without thrombophilia, and antithrombotic therapy. Only advancing maternal age had significant correlation to increased embryo chromosomal aberration rates. CONCLUSIONS With or without antithrombotic therapy, miscarriage was caused by embryonic chromosome abnormalities at a certain rate. Antithrombotic therapy in RPL patients with thrombophilia may reduce abortions due to thrombophilia, which may also normalize the rate of embryonic chromosome aberrations in the subsequent miscarriages.

Reprod Biomed Online 2021; 42:1146-1171. [PMID: 33895080 DOI: 10.1016/j.rbmo.2021.02.014] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2020] [Revised: 02/22/2021] [Accepted: 02/23/2021] [Indexed: 10/22/2022]
Abstract
Recurrent miscarriage affects 1-2% of women of reproductive age, depending on the definition used. A systematic review was conducted to identify, appraise and describe clinical practice guidelines (CPG) published since 2000 for the investigation, management, and/or follow-up of recurrent miscarriage within high-income countries. Six major databases, eight guideline repositories and the websites of 11 professional organizations were searched to identify potentially eligible studies. The quality of eligible CPG was assessed using the Appraisal of Guidelines for Research and Evaluation (AGREE II) Tool. A narrative synthesis was conducted to describe, compare and contrast the CPG and recommendations therein. Thirty-two CPG were included, from which 373 recommendations concerning first-trimester recurrent miscarriage were identified across four sub-categories: structure of care (42 recommendations, nine CPG), investigations (134 recommendations, 23 CPG), treatment (153 recommendations, 24 CPG), and counselling and supportive care (46 recommendations, nine CPG). Most CPG scored 'poor' on applicability (84%) and editorial independence (69%); and to a lesser extent stakeholder involvement (38%) and rigour of development (31%). Varying levels of consensus were found across CPG, with some conflicting recommendations. Greater efforts are required to improve the quality of evidence underpinning CPG, the rigour of their development and the inclusion of multi-disciplinary perspectives, including those with lived experience of recurrent miscarriage.

Abstract
OBJECTIVE This study aimed to evaluate perinatal outcomes in women with a history of recurrent pregnancy loss. STUDY DESIGN Retrospective cohort study of singleton and nonanomalous gestations at ≥ 20 weeks who delivered at our academic institution. The exposed group was defined as women with a history of ≥ 2 consecutive spontaneous abortions (SABs) at < 12 weeks. These women were compared with women with a history of ≤ 1 SAB at < 12 weeks. The primary outcome was preterm birth (PTB) at < 37 weeks. Secondary outcomes included gestational age at delivery, gestational diabetes, small for gestational age birth weight, hypertensive diseases of pregnancy, fetal demise, cesarean delivery, and a composite of neonatal complications (5-minute Apgar score < 5, perinatal death, and NICU admission). Multivariable logistic regression was performed to adjust for confounders. RESULTS Of 17,670 women included, 235 (1.3%) had a history of ≥ 2 consecutive SABs. Compared with women with a history of ≤ 1 SAB, women with ≥ 2 consecutive SABs were not more likely to have a PTB (19.6 vs. 14.0%, p = 0.01, adjusted odds ratios (AOR): 0.91, 95% confidence interval [CI]: 0.62-1.33). However, they were more likely to deliver at an earlier mean gestational age (37.8 ± 3.4 vs. 38.6 ± 2.9 weeks, p < 0.01) and to have gestational diabetes (12.3 vs. 6.6%, p < 0.01, AOR: 1.69, 95% CI: 1.10-2.59). Other outcomes were similar between the two groups. CONCLUSION A history of ≥ 2 consecutive SABs was not associated with an increased incidence of PTB but may be associated with gestational diabetes in a subsequent pregnancy. KEY POINTS · This was a retrospective cohort study.. · Women with a history of recurrent pregnancy loss (RPL) were studied.. · RPL was associated with an increase in preterm birth..

Abstract
PURPOSE To identify risk factors for severe psychological stress in women undergoing fertility treatment. METHODS This cross-sectional, multi-center study was conducted from August to December 2018. We recruited 1672 subjects who completed an anonymous, self-reported questionnaire regarding fertility treatment, conditions at work and home, and psychological stress using K6 score, which estimates psychological distress during the previous 30 days. We further focused our analysis on 1335 subjects who were working when starting fertility treatment. RESULTS Of 1672 women, mean K6 score (range 0-24) was 4.8 ± 4.4, including 103 women (6.2%) with K6 score ≥ 13 (high K6), and classified as probable severe psychological distress. Multivariate logistic regression analysis showed that high K6 was strongly associated with low annual family income of ≤ USD55,700 (JPY6 million) (odds ratio [OR] 1.89, 95% confidence interval [CI] 1.04-3.42), infertility duration of ≥ 2 years (OR 1.87, 95% CI 1.08-3.25), and no experience of childbirth (OR 2.04, 95% CI 1.05-3.97). Focusing on 1335 working women, 266 (19.9%) experienced resignation from work. High K6 was strongly associated with low family income (OR 2.83, 95% CI 1.52-5.28), cessation of professional duties (OR 2.08, 95% CI 1.05-4.14), infertility-related harassment in the workplace (OR 2.07, 95% CI 1.08-3.98), and perceived difficulties to continue working during fertility treatment (OR 2.94, 95% CI 1.15-7.50). CONCLUSION Severe psychological stressors in women during fertility treatment included low family income, long infertility duration, childlessness, infertility-related harassment, and perceived difficulty in working conditions or cessation from work. Establishment of mental health care support systems is urgently required in this population.

Abstract
Recurrent miscarriage (RM) was recently re-defined by the European Society of Human Reproduction and Embryology (ESHRE) as the loss of two or more consecutive pregnancies. Before this, and indeed still in some countries, RM was defined as three or more consecutive pregnancy losses. While the incidence of RM depends on the definition employed and population studied, it is generally accepted to affect 1-6% of women of reproductive age. Clinical practice guidelines (CPGs) for RM have been published by some professional organisations. While there are CPGs on miscarriage in Ireland, there are none concerning RM specifically. The aim of this systematic review is to identify, appraise and describe published CPGs for the management, investigation and/or follow-up of RM within high-income countries. Electronic databases (MEDLINE (Ovid

Two reviewers will review abstracts and full texts independently against the eligibility criteria. Characteristics and recommendations of included CPGs will be extracted by one reviewer and double-checked by another. Two reviewers will use the Appraisal of Guidelines for Research and Evaluation version 2 (AGREE II) instrument independently to assess the quality of the included CPGs. Narrative synthesis will be conducted to appraise and compare CPGs and their recommendations or guidance therein. The identification, appraisal and description of published CPGs in other high-income countries will be a valuable first step in informing efforts to promote the optimisation and standardisation of RM care.

Abstract
PROBLEM While there are several known causes for recurrent pregnancy loss (RPL), about 50% are unexplained (uRPL), and in these cases, an aberrant immune regulation seems to be involved. Although fetally derived trophoblast cells have a key role in immune regulation, it is difficult to study their immune function during pregnancy, and it is not known whether trophoblast function may be an inherent aberration in uRPL or whether it is associated with the outcome of the current pregnancy. METHOD OF STUDY Chorionic villus sampling (CVS) was performed for clinical indications at 12 weeks of gestation. Superfluous materials, divided in small explants, were cultured for 20-24 hours, and supernatants (conditioned medium) were collected from 36 women with singleton normal pregnancies, of whom 9 women had a history of RPL. The secreted immune protein profile was measured by proximity extension assay, and the conditioned medium was further used in functional ex vivo models to assess ability to polarize blood monocytes and CD4+ T cells into immune regulatory phenotypes, as detected by flow cytometry. RESULTS Conditioned medium from chorionic villi, human fetally derived placental tissue, was able to induce a decidual-type of M2-like macrophages, as well as an expansion of Treg cells ex vivo, both in women with uRPL and in control women. The preserved immunological properties were confirmed by a maintained immune protein profile in RPL compared with controls. CONCLUSION Trophoblasts in an ex vivo model maintain tolerogenic and proteomic profile features in successful pregnancies, despite a previous history of RPL.

Abstract
OBJECTIVE To know the prevalence of immunology as a cause of unexplained repeated pregnancy loss (RPL) by comparing T helper cell 1(Th1) and T helper cell 2 (Th2) in the decidua of women with RPL, at the time of miscarriage with the decidua of women, at the time of induced abortion. STUDY DESIGN case control study SETTING: Academic medical centre SUBJECTS: 36 Women requiring surgical evacuation, with history of previous one or more spontaneous abortions enrolled as cases. 37 patients undergoing surgically induced termination of pregnancy taken as control. Inclusion criteria- women who presented to the hospital with signs of abortion requiring surgical evacuation, with history of previous one or more spontaneous abortion. Exclusion criteria- women who had taken progesterone for present pregnancy, prior to this miscarriage. Also women who had clinical evidence of autoimmune disease, who were critically ill and who had biohazard exposures like HIV, HCV, HBsAg. INTERVENTION The decidual tissue obtained was subjected to histopathology and immunohistochemistry staining for Th1 and Th2 cells. STATISTICAL ANALYSIS Data entered in MS EXCEL spreadsheet and analysis done using Statistical Package for Social Sciences (SPSS) version 21.0. RESULTS The Th1 cells were found to be positive in 25 % women in cases and 29.73 % women in controls group whereas Th2 cells were positive in 16.67 % women in cases and 8.11 % in control group. Both Th1 and Th2 cells were seen in 16.44 % of total women. (p- 0.678) CONCLUSION: No statistically significant difference in Th1 and Th2 cells in the decidua of patients undergoing recurrent abortion when compared to women undergoing medical termination of pregnancy. Therefore, routine screening for immunological factors and cytokine testing is not recommended. Patients of RPL should not be offered immune treatment routinely.

Immunotherapy to improve pregnancy outcome in women with abnormal natural killer cell levels/activity and recurrent miscarriage or implantation failure: A systematic review and meta-analysis.

Abstract
There is a trend towards offering immunotherapy to women with unexplained reproductive failure based on abnormal Natural Killer (NK) cell levels. Previous systematic reviews evaluating immunotherapy usage have not focused on women with abnormal level of NK cells. To address the gap in literature, this systematic review aims to evaluate the efficacy of immunotherapy to improve pregnancy outcome in women with recurrent miscarriage (RM) or implantation failure (RIF) specifically selected based on abnormal levels and/or activity of NK cells. Six databases were searched for peer-reviewed studies following PRISMA guidelines. Risk of bias assessment was conducted using RoB2 for randomized controlled trials (RCT) and ROBINS-I for non-RCT. Of 1025 studies identified, seven studies on intravenous immunoglobulin (IVIG) (four), prednisolone (one), etanercept (one) and intralipid (one) were included. Meta-analysis of the non-RCT IVIG studies (557 participants; 312 intervention, 245 controls) showed livebirth in favour of intervention (RR 2.57; 95 % CI = 1.79-3.69; p < 0.05), however there were significant heterogeneity (I2 = 62 %) and moderate to severe risk of bias in these studies. Individual RCTs reported improved livebirth outcome in etanercept, intralipid and prednisolone and this was significant in the former two (p < 0.05). In conclusion, there may be some benefit of immunotherapy, but paucity of high quality evidence means that it is not possible to support the use of immunotherapy even when selected based on abnormal NK cell level/activity. Further research with application of scientifically validated immunological biomarkers in well-planned large scale RCTs will determine whether immunotherapy is beneficial in this subpopulation of women.

[PMID: 32994741 PMCID: PMC7499272 DOI: 10.1016/j.sjbs.2020.06.049] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2020] [Revised: 06/19/2020] [Accepted: 06/29/2020] [Indexed: 01/28/2023] Open
Abstract
The purpose of this study was to evaluate etiology and pregnancy outcome of recurrent miscarriage women. The enrolled patients (280) were evaluated for Triiodothyronine, Thyroxine, Thyroid stimulating hormone, prolactin, chromosomal analysis, Haemoglobin A1C, blood sugar, Magnetic resonance imaging, 3D-ultrasound, auto-antibodies profile (antiphospholipid antibodies, anticardiolipin antibodies, lupus anticoagulant, antinuclear antibodies, anti-thyroid antibodies and β2 glycoprotein1), torch profile (Toxoplasmo gondii, rubella, cytomegalo virus and herpes simplex virus), blood vitamin D3 levels, psychological factors, Body mass index and thrombotic factors (protein S and C deficiency, Prothrombin G20210A mutation, anti-thrombin III, Factor V Leiden and Methylenetetrahydrofolate reductase mutation), uterosalpingography (hysteronsalpingography) and hysteroscopy. The therapeutic regimens either singly or combined were employed for the treatment of recurrent miscarriage patients on the basis of etiology (single or multiple) and include intravenous immunoglobulin, low molecular weight heparin, low dose aspirin, levothyroxine, progesterone, folic acid, human chorionic gonadotrophin, vitamin D3, psychotherapy, genetic counselling. However, patients with idiopathic recurrent miscarriage were treated with progesterone supplementation, anticoagulation and/or immune modulatory agents. The incidence of primary recurrent miscarriage was highest and most of the women experienced recurrent miscarriage during first trimester. Endocrinological disorders (39%) were found as the major pathological factor for recurrent miscarriage. Other factors include uterine abnormalities (5.7%), vitamin D3 deficiency (3.5%), psychological factors (3.2%) infection (3.6%), autoimmune abnormalities (1.8%) and protein S deficiency (1.8%). However, 40% cases were idiopathic. The overall live birth rate achieved after the management of recurrent miscarriage patients was 75.7%. Enocrinopathy was the major cause of recurrent miscarriage. The overall live birth rate achieved was 75.7% with highest pregnancy outcome in secondary recurrent miscarriage patients after the management.

Abstract
In clinical practice, empirical treatments are often offered to couples with recurrent pregnancy loss, including in vitro fertilization. Given that most patients with recurrent pregnancy loss are fertile, the scientific rationale of in vitro fertilization for these couple is debatable. This review will discuss the potential benefits of using in vitro fertilization in couples with recurrent pregnancy loss, such as shortening the time to conceive, optimizing the timing of conception, improving gamete and embryo quality, endometrial receptivity and the use of "adds-on". At present, there is not enough evidence to justify IVF as a treatment option in couples with unexplained recurrent pregnancy loss.

Abstract
Our understanding of the relationship between stress-derived epinephrine and early pregnancy failure remains incomplete. Here, we explored the effect of epinephrine exposure on early pregnancy and pseudopregnancy in mice. Increased expression of adrenergic receptors Adra1b, Adra2b and Adrb2 was observed during decidualization and post-implantation embryogenesis was delayed or survival impaired. Epinephrine treatment also impaired decidualization in both the gravid and pseudopregnant uterus, suggesting the effect on decidualization was independent of the conceptus. This included a suppression of endometrial stroma cell proliferation and of key decidualization regulators, including COX2, BMP2 and WNT4. Collectively, these data demonstrate that maternal epinephrine exposure during early pregnancy impairs uterine decidualization and embryo development, underlying early pregnancy failure.

Abstract
Low-molecular-weight heparin (LMWH) is widely used to treat recurrent pregnancy loss (RPL) because of its anti-coagulant effects. Although in vitro studies have suggested additional immunological effects, these are debated. We therefore investigated whether LMWH could modulate immune responses in vivo during pregnancy of women with unexplained RPL. A Swedish open multi-centre randomised controlled trial included 45 women treated with tinzaparin and 42 untreated women. Longitudinally collected plasma samples were obtained at gestational weeks (gw) 6, 18, 28 and 34 and analysed by multiplex bead technology for levels of 11 cytokines and chemokines, chosen to represent inflammation and T-helper subset-associated immunity. Mixed linear models test on LMWH-treated and untreated women showed differences during pregnancy of the Th1-associated chemokines CXCL10 (p = 0.01), CXCL11 (p < 0.001) and the Th17-associated chemokine CCL20 (p = 0.04), while CCL2, CCL17, CCL22, CXCL1, CXCL8, CXCL12, CXCL13 and IL-6 did not differ. Subsequent Student's t-test showed significantly higher plasma levels of CXCL10 and CXCL11 in treated than untreated women at gw 28 and 34. The consistent increase in the two Th1-associated chemokines suggests a potential proinflammatory and unfavourable effect of LMWH treatment during later stages of pregnancy, when Th1 immunity is known to disrupt immunological tolerance.

Abstract
The definition of recurrent miscarriage ranges from two miscarriages according to the American Society for Reproductive Medicine and the European Society of Human Reproduction and Embryology, to three consecutive pregnancy losses as defined by the Royal College of Obstetricians and Gynaecologists. Recent guidelines emphasise the need for further research on the effect of various recurrent miscarriage definitions on diagnosis, treatment and prognosis. Our study examines the management and pregnancy outcomes of nulliparous women attending Cork University Maternity Hospital's Pregnancy Loss Clinic, between 2009 and 2014, with their second consecutive first-trimester miscarriage. Information was sourced from the Pregnancy Loss Clinic's database, hospital patient management and laboratory systems, and clinical letters. 294 women were identified. A subsequent pregnancy was conceived by 82.3% (242/294) of women, with 72.7% (176/242) achieving a live birth. In conclusion, supportive care and selective medical management in dedicated pregnancy loss and early pregnancy clinics achieve excellent reproductive outcomes. Impact Statement What is already known on this subject? The definition of recurrent miscarriage is varied. It ranges from two miscarriages according to the American Society for Reproductive Medicine and the European Society of Human Reproduction and Embryology, to three consecutive pregnancy losses as defined by the Royal College of Obstetricians and Gynaecologists. Recurrent miscarriage affects between 1 and 5% of women. Past studies suggest several causative factors, including epidemiologic, genetic, anatomical and endocrine. These factors may be identified in up to 50% of women with recurrent losses. Subsequent pregnancy outcomes are reported as excellent. However, recent guidelines focus on the need for further research on the effect of the various recurrent miscarriage definitions on diagnosis, investigation, treatment and prognosis. What the results of this study add? This study examined the management and pregnancy outcomes of women with two consecutive losses. A causative factor was identified in 29.3% of women in our cohort. A subsequent pregnancy was conceived by 82.3%, with 72.7% achieving a live birth. We suggest that supportive care is the single most effective therapy for women with two consecutive losses. What the implications are of these findings for clinical practice and/or further research? Over-investigation and empirical treatment should be avoided, with a greater emphasis placed on psychological support and risk factor modification in this group. Investigation protocols must be refined to only search for causes of recurrent miscarriage with evidence based treatment. Evaluation of supportive care in randomised control trials is needed.

Abstract
The current evidence-based guidelines for the evaluation of recurrent pregnancy loss recommended by the American Society for Reproductive Medicine and by the European Society of Human Reproduction and Embryology are compared and contrasted in this review. The clinical use of either of these guidelines will result in a probable diagnosis for only half of the affected patients. New strategies for a full evaluation of recurrent pregnancy loss incorporating 24- chromosome microarary on the products of conception offer more explanations for patients and caregivers. This new algorithm should decrease the use of empiric, unproven treatments. Combining the results of genetic testing on the miscarriage tissue with the conventional diagnostic tests has made it possible to explain the etiology of pregnancy loss in more than 90% of the cases. This cost-saving strategy can decrease the emotional distress and frustration for both couples and physicians when it comes to management of recurrent pregnancy loss.

Abstract
The aim of this study was to investigate the association between female reproductive status and risk of spontaneous abortion among female workers in the Jinchang Cohort. This study used data obtained from a baseline survey of the Jinchang Cohort Study of female workers in Jinchang Industry, the largest nickel production company in China. A standardized, structured questionnaire was used to collect the health status of 18,834 female workers employed by the company from 2011 to 2013. Spearman grade correlation analysis and logistic regression models were used to evaluate the association between female reproductive status and risk of spontaneous abortion. The incidence rate of spontaneous abortion was 6.89%, and fatigue was associated with the risk of spontaneous abortion. The number of pregnancies, age at primary birth and age at the last pregnancy were associated with an increased risk of spontaneous abortion (rs = 0.190, p = 0.000; rs = 0.092, p = 0.000; rs = 0.061, p = 0.000; respectively). In addition, there was a negative correlation between the number of artificial abortions and spontaneous abortions (rs = −0.129, p = 0.000). Female reproductive status was associated with an increased risk of spontaneous abortion in this cohort. More studies are needed to confirm this observed association.

Abstract
Purpose To evaluate whether anti-Mullerian hormone, basal follicle-stimulating hormone, luteinizing hormone, estradiol, and female age would predict future outcomes in women with idiopathic recurrent miscarriage. Methods One hundred and sixteen women with idiopathic recurrent miscarriage were retrospectively included. Luteal support with or without a combined treatment regimen for idiopathic recurrent miscarriage was applied in a tertiary-care center in Vienna. Occurrence and outcome of further pregnancies were analyzed. Results Within a median follow-up duration of 42.3 months, 94 women (81.0%) achieved one or more pregnancies. Further miscarriages occurred in 47 patients in whom only a higher number of previous miscarriages was predictive (OR 3.568, 95% CI 1.457–8.738; p = 0.005). Fifty-seven women had a live birth > 23 + 0 gestational weeks. In a multivariate analysis, age (OR 0.920, 95% CI 0.859–0.986; p = 0.019) and the number of previous miscarriages (OR 0.403, 95% CI 0.193–0.841; p = 0.016), but not AMH (OR 1.191, 95% CI 0.972–1.461; p = 0.091) were significantly predictive. Conclusion AMH seems of either no or only minor relevance for the prediction of further miscarriages and live birth in women with idiopathic recurrent miscarriage.

Abstract
INTRODUCTION Recurrent pregnancy loss occurs in about 1% of fertile couples. Without proper evidence for an effect, different treatments have been used when no etiological factor has been detected. The present trial is the first randomized trial to compare 75 mg acetylsalicylic acid with placebo for women with recurrent pregnancy loss. MATERIAL AND METHODS This randomized, double-blind, placebo-controlled trial was conducted at a single center between 2008 and 2015. Recurrent pregnancy loss was defined as at least 3 consecutive first-trimester miscarriages within the couple. Women < 40 years old with a body mass index < 35 kg/m2 were eligible if the workup was negative. Randomization was through a third party, who manufactured and delivered the study drugs, and occurred when fetal heartbeat was detected, to either 75 mg acetylsalicylic acid or placebo; 200 women in each group. Group allocation was concealed until all the study participants had a pregnancy outcome registered. All women attended the same control program. Primary outcome was live birth. Statistical analyses were according to intention-to-treat. RESULTS All 400 women completed the follow up. Live birth rate was 83.0% (n = 166) and 85.5% (n = 171) for the acetylsalicylic acid and placebo groups, respectively (P = 0.58). The difference was -2.5% (95% CI -10.1% to 5.1%). The risk ratio was 0.97 (95% CI 0.89-1.06). CONCLUSIONS Treatment with acetylsalicylic acid did not prevent recurrent miscarriage in women with at least three consecutive miscarriages in the first trimester, of unknown reasons and in the same relationship. The fertility prognosis is very good, the live birth rate being > 80% with or without acetylsalicylic acid.

Abstract
Recurrent pregnancy loss (RPL) affects close to 1% of couples; however, the etiology is known in only about 50% of the cases. Recent studies show that autoimmune dysregulation is a probable cause of RPL, which in some cases may be overlooked. In order for a pregnancy to proceed to term, early modulation of immunologic response is required to induce tolerance to the semi-allogenic fetus. Certain subsets of both the innate and adaptive immune responses play a role in the induction of fetomaternal tolerance. A relatively predominant T-cell helper (Th) 2 and T regulatory (Treg) cell population seem to favor a better pregnancy outcome, whereas Th1 and Th17 cell populations appear to have an opposite effect. Lately, the role of vitamin D in the modulation of immune response was established. Vitamin D has been shown to promote a more favorable environment for pregnancy through various mechanisms, such as enhancement of the shift toward Th2 cells and regulation of immune cell differentiation and cytokine secretion. Therefore, it seems that vitamin D deficiency sways the balance toward a worse outcome and may play a part in recurrent pregnancy loss. This review sheds light on the immunologic changes, which occur in early pregnancy and the regulatory role vitamin D has in the maintenance of this delicate balance.

Abstract
INTRODUCTION Medical treatment of women with idiopathic recurrent pregnancy loss is controversial. The objective was to assess the effects of different treatments on live birth rates and complications in women with unexplained recurrent pregnancy loss. MATERIAL AND METHODS We searched MEDLINE, Embase and the Cochrane Library, and identified 1415 publications. This systematic review included 21 randomized controlled trials regarding acetylsalicylic acid, low-molecular-weight heparin, progesterone, intravenous immunoglobulin or leukocyte immune therapy in women with three or more consecutive miscarriages of unknown cause. The study quality was assessed and data was extracted independently by at least two authors. RESULTS No significant difference in live birth rate was found when acetylsalicylic acid was compared with low-molecular-weight heparin or with placebo. Meta-analyses of low-molecular-weight heparin vs. control found no significant differences in live birth rate [risk ratio (RR) 1.47, 95% CI 0.83-2.61]. Treatment with progesterone starting in the luteal phase seemed effective in increasing live birth rate (RR 1.18, 95% CI 1.09-1.27) but not when started after conception. Intravenous immunoglobulin showed no effect on live birth rate compared with placebo (RR 1.07, 95% CI 0.91-1.26). Paternal immunization compared with autologous immunization showed a significant difference in outcome (RR 1.8, 95% CI 1.34-2.41), although the studies were small and at high risk of bias. CONCLUSION The literature does not allow advice on any specific treatment for idiopathic recurrent pregnancy loss, with the exception of progesterone starting from ovulation. We suggest that any treatment for recurrent pregnancy loss should be used within the context of a randomized controlled trial.

Abstract
OBJECTIVE Parental carriers of balanced structural chromosomal rearrangements such as reciprocal or Robertsonian translocations are at increased risk of recurrent pregnancy loss (RPL) due to the production of gametes with unbalanced non-viable chromosome variants. As a purported means of improving reproductive outcomes in this population, IVF and preimplantation genetic diagnosis (PGD) have been introduced as an alternative to natural conception and prenatal diagnosis. In this study, we evaluate the prevalence and treatment choices of couples with structural chromosomal rearrangement referred to a tertiary care RPL clinic. In addition, we compare the two methods of management in terms of live birth rate. METHODS This is a retrospective chart review of 2321 couples who were referred to a highly specialized RPL clinic for ongoing clinical management between January 2005 and December 2013 (n = 23). Couples who pursued PGD through local fertility centres during this time were also included (n = 13). RESULTS Thirty-six couples (1.6%) were found to be parental carriers of a structural chromosomal rearrangement. In this cohort, couples were twice as likely to pursue natural conception compared with IVF with PGD. No significant differences were observed in live birth rate between PGD and clinical management (66.6% vs. 53.3%, P = 0.717). With PGD management, six live birth outcomes were observed, with an incidence of one birth in 5.63 years of follow-up. With clinical management, 24 live birth outcomes were observed, with an incidence of one birth in 4.09 years of follow-up. Mean time to live birth was 17.5 months and 23.3 months in clinical management and PGD, respectively. CONCLUSIONS Among couples presenting to a tertiary RPL clinic, parental carriers of structural chromosomal rearrangement and history of RPL are more likely to pursue natural conception over IVF and PGD. With regards to reproductive outcomes, no significant difference in miscarriage rate, time to live birth, or live birth rate was observed between couples who pursued PGD compared with expectant clinical management.

Abstract
OBJECTIVES Theories of reproductive suppression predict that natural selection would conserve mechanisms that abort the gestation of offspring otherwise unlikely to thrive in prevailing environments. Research reports evidence among humans of at least two such mechanisms-the Trivers-Willard and Bruce Effects. No literature, however, compares the mechanisms nor estimates their relative contribution to observed characteristics of human birth cohorts. We describe similarities and differences between the Trivers-Willard and Bruce Effects and explore high quality historical data from Sweden to determine which mechanism better describes temporal variation in the ratio of males to females in birth cohorts. METHODS We measure Trivers-Willard exposures with the death rate among women of reproductive age. We measure Bruce exposures with the death rate among children. We use time-series regression methods to estimate the relative contribution of the Trivers-Willard and Bruce Effects to temporal variation in historical Swedish secondary sex ratio data. RESULTS We find that the Bruce Effect appears to be a better predictor of the secondary sex ratio than does the Trivers-Willard Effect. CONCLUSIONS Attempts to identify mechanisms by which reproductive suppression affects fetal loss and characteristics of human birth cohorts should consider the Bruce Effect as an alternative to the Trivers-Willard Effect.

Abstract
Purpose Recurrent pregnancy losses (RPL) are considered a pathological condition associated with heterogeneous laboratory and clinical findings, and are also linked to subfertility. We attempt to rank parameters derived from past history and diagnostic results with regard to the prognosis. Methods Observational trial on 719 consecutive couples who were referred to a tertiary immunological care centre (2006–2014) after three or more primary miscarriages. Information on past obstetric history and diagnostic procedures at baseline were correlated with cumulative pregnancy and delivery rates using Kaplan–Meier estimation, logistic regression and multivariate analysis. Results At baseline, median female age was 34.1 years, waiting time 3 years (1–17), number of preceding miscarriages 3 (3–9), 147 women (20.4%) had conceived at least once in ART or AIH cycles. After a median follow-up of 33.7 (1.7–123.0) months, 5-year pregnancy and delivery rates were 86.1 and 64.5%. Female age (< 35 years), waiting time (< 3 years) until baseline, tubal competence, and male factor fertility significantly correlated with favourable outcome (p < 0.001), while body mass index (> 29 kg/m2), number of preceding miscarriages (> 4), late miscarriages, preclinical losses and smoking revealed non-significant negative trends. Mode of conception until baseline (spontaneously or ART/AIH) and classification into idiopathic and non-idiopathic RPL showed no prognostic relevance. Conclusion Although in general, chances to conceive a child are retained after three or more miscarriages, factors related to subfertility of both partners have an important impact on the outcome. Therefore, prolonged time to pregnancy (> 6–9 months) should result in preventive gynaecological care from the first miscarriage on, so that fertility can be preserved as best as possible.

Abstract
Recurrent pregnancy loss (RPL), commonly defined as 3 consecutive losses <10 weeks gestation, affects up to 5% of couples. Well-accepted causes include uterine malformation, antiphospholipid syndrome, and parental chromosomal abnormalities; however, the majority of RPL cases are idiopathic (up to 75%). This chapter covers these accepted causes of RPL and provides diagnosis and management strategies for patients falling within the above categories.

Abstract
OBJECTIVE The aim of this systematic review was to assess the effect of interventions to reduce stress in pregnant women with a history of miscarriage. DESIGN A systematic review of randomised controlled trials (RCTs). DATA SOURCE A total of 13 medical, psychological and social electronic databases were searched from January 1995 to April 2016 including PUBMED, CENTRAL, Web of Science and EMBASE. ELIGIBILITY CRITERIA This review focused on women in their subsequent pregnancy following miscarriage. All published RCTs which assessed the effect of non-medical interventions such as counselling or support interventions on psychological and mental health outcomes such as stress, anxiety or depression when compared with a control group were included. Stress, anxiety or depression had to be measured at least preintervention and postintervention. RESULTS This systematic review found no RCT which met our initial inclusion criteria. Of the 4140 titles screened, 17 RCTs were identified. All of them were excluded. One RCT, which implemented a caring-based intervention, included pregnant women in their subsequent pregnancy; however, miscarriage was analysed as a composite variable among other pregnancy losses such as stillbirth and neonatal death. Levels of perceived stress were measured by four RCTs. Different types of non-medical interventions, time of follow-up and small sample sizes were found. CONCLUSION Cohort studies and RCTs in non-pregnant women suggest that support and psychological interventions may improve pregnant women's psychological well-being after miscarriage. This improvement may reduce adverse pregnancy-related outcomes in subsequent pregnancies. However, this review found no RCTs which met our criteria. There is a need for targeted RCTs that can provide reliable and conclusive results to determine effective interventions for this vulnerable group.

Abstract
The human sex ratio (proportion male) at birth (SRB) varies with many variables. Some of this variation has an established proximate cause. For instance, low SRB (more females) at birth are associated with various forms of stressful events or circumstances during or prior to pregnancy. These low SRB are almost certainly mainly caused by maternal-stress-induced male foetal loss. Other types of SRB variation are thought to be caused by hormonal variation in either or both parents around the time of conception. One or other of these two types of proximate cause seems to be responsible for most of the established variation of SRB. This will be illustrated here in respect of some selected forms of SRB variation. It seems likely that a clarification of the hormonal causes of SRB variation will also help explain the striking (apparent) inconsistencies in the results of reported tests of the influential Trivers-Willard hypothesis. It is further proposed that an appreciation of the evidence that parental hormones influence SRB may enhance understanding of several important pathologies (hepatitis B, toxoplasmosis, testicular cancer, prostate cancer and autism).
