Fertil Steril 2023; 120:626-634. [PMID: 37121567 DOI: 10.1016/j.fertnstert.2023.04.028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2022] [Revised: 04/20/2023] [Accepted: 04/20/2023] [Indexed: 05/02/2023]
Abstract
OBJECTIVE To examine the associations between a history of recurrent miscarriage (RM) and adverse obstetric and perinatal outcomes in the subsequent pregnancy that progressed beyond 24 weeks. DESIGN Retrospective cohort study. SETTING A large tertiary maternity hospital. PATIENT(S) All women who booked for antenatal care and delivery between January 2014 and August 2021 were recorded. The study was limited to women with a singleton pregnancy, and to avoid intraperson correlation, we selected the first record of delivery from each mother in the study, leaving 108,792 deliveries for analysis. Obstetric and perinatal outcomes were compared among 1994 women (1.83%) with a history of ≥2 miscarriages (RM), 11,477 women (10.55%) with a history of 1 miscarriage, and 95,321 women (87.62%) with no history of miscarriage, respectively. INTERVENTION(S) Women with a history of ≥2 miscarriages or RM. MAIN OUTCOME MEASURE(S) Obstetric complications included gestational diabetes mellitus, preeclampsia (subclassified as preterm and term preeclampsia), placenta previa, placenta accreta, and fetal distress. Perinatal outcomes included emergency cesarean section, elective cesarean section, induction, postpartum hemorrhage, preterm birth, stillbirth, Apgar score <7 at 5 minutes, neonatal asphyxia, neonatal sex, congenital; malformation, low birth weight, and neonatal death. RESULT(S) After adjusting for relevant confounders, there was an increased risk of adverse obstetric and perinatal outcomes in a subsequent pregnancy for women with a history of RM, specifically for placental dysfunction disorders: preterm preeclampsia (risk ratio [RR] = 1.58; 95% confidence interval [CI], 1.03-2.32), preterm birth (RR = 1.34; 95% CI, 1.15-1.54)], and abnormal placentation, that is placenta previa (RR = 1.78; 95% CI, 1.36-2.28), and placenta accreta (RR = 4.19; 95% CI, 2.75-6.13). CONCLUSION(S) Significant associations existed between a history of RM and the occurrence of adverse obstetric and perinatal outcomes including placental dysfunction disorders and abnormal placentation. These findings may contribute to the early detection and appropriate intervention for placenta-associated diseases in women with a history of RM, with the goal of avoiding or reducing the associated detrimental effects.

J Headache Pain 2022; 23:162. [PMID: 36539705 PMCID: PMC9764528 DOI: 10.1186/s10194-022-01533-6] [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: 08/31/2022] [Accepted: 12/08/2022] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Migraine is common among females of reproductive age (estimated prevalence:17-24%) and may be associated with reproductive health through underlying central nervous system excitability, autoimmune conditions, and autonomic dysfunction. We evaluated the extent to which pre-pregnancy migraine diagnosis and medication use are associated with risk of spontaneous abortion (SAB). METHODS We analyzed data from a preconception study of pregnancy planners (2013-2021). Eligible participants self-identified as female, were aged 21-45 years, resided in the USA or Canada, and conceived during follow-up (n = 7890). Participants completed baseline and bimonthly follow-up questionnaires for up to 12 months or until a reported pregnancy, whichever occurred first. Pregnant participants then completed questionnaires during early (~ 8-9 weeks) and late (~ 32 weeks) gestation. We defined migraineurs as participants who reported a migraine diagnosis or use of a medication to treat migraine. Preconception questionnaires elicited migraine medication use during the past 4 weeks, and SAB on follow-up and pregnancy questionnaires. We used Cox regression models with gestational weeks as the time scale to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for associations among preconception migraine, migraine medication use, and SAB, controlling for potential demographic, medical, and lifestyle confounders. RESULTS Nineteen percent of study pregnancies ended in SAB. History of migraine before conception was not appreciably associated with SAB risk (HR = 1.03, 95% CI: 0.91-1.06). Use of any migraine medication was associated with a modest increase in SAB risk overall (HR = 1.14, 95% CI: 0.96-1.36). We observed the greatest increase in risk among those taking migraine medications daily (HR = 1.38, 95% CI: 0.81-2.35) and those taking prescription migraine prophylaxis (HR = 1.43, 95% CI: 0.72-2.84) or combination analgesic and caffeine medications (HR = 1.42, 95% CI: 0.99-2.04). CONCLUSIONS Migraine medication use patterns suggesting greater underlying migraine severity were associated with increased risk of SAB. This research adds to the limited information available on the reproductive effects of migraine.

[PMID: 35843271 PMCID: PMC10395050 DOI: 10.1016/j.ajog.2022.07.007] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2022] [Revised: 07/06/2022] [Accepted: 07/07/2022] [Indexed: 01/27/2023]
Abstract
BACKGROUND The assessment and management of patients with threatened midtrimester miscarriage is a clinical challenge because the etiology of this condition is poorly understood. OBJECTIVE This study aimed to examine the frequency of intraamniotic infection or inflammation and the effect of antibiotics in patients presenting with regular uterine contractions and intact membranes before 20 weeks of gestation. STUDY DESIGN This retrospective study comprised patients who met the following criteria: (1) singleton gestation, (2) gestational age before 20 weeks, (3) the presence of regular uterine contractions confirmed by a tocodynamometer (8 or more contractions in 60 minutes), (4) intact amniotic membranes, and (5) transabdominal amniocentesis performed for the evaluation of the microbiologic and inflammatory status of the amniotic cavity. Samples of amniotic fluid were cultured for aerobic and anaerobic bacteria and genital mycoplasmas, and polymerase chain reaction was performed to detect Ureaplasma species. Amniotic fluid was tested for white blood cell counts and matrix metalloproteinase-8 concentrations to diagnose intraamniotic inflammation. Patients with intraamniotic inflammation, or intraamniotic infection, were treated with antibiotics (a combination of ceftriaxone, clarithromycin, and metronidazole). Treatment success was defined as the resolution of intraamniotic infection/inflammation at the follow-up amniocentesis or delivery after 34 weeks of gestation. RESULTS 1) Intraamniotic inflammation was present in 88% (15/17) of patients, whereas infection was detectable in only 2 cases; 2) objective evidence of resolution of intraamniotic inflammation after antibiotic treatment was demonstrated in 100% (4/4) of patients who underwent a follow-up amniocentesis; 3) 30% (5/15) of women receiving antibiotics delivered after 34 weeks of gestation (3 of the 5 patients had a negative follow-up amniocentesis, and 2 of the women were without a follow-up amniocentesis); 4) the overall treatment success of antibiotics was 40% (6/15; 4 cases of objective evidence of resolution of intra-amniotic inflammation and 5 cases of delivery after 34 weeks of gestation). CONCLUSION The prevalence of intraamniotic inflammation in patients who presented with a threatened midtrimester miscarriage was 88% (15/17), and, in most cases, microorganisms could not be detected. Antibiotic treatment, administered to patients with intraamniotic inflammation, was associated with either objective resolution of intraamniotic inflammation or delivery after 34 weeks of gestation in 40% (6/15) of the cases.

[PMID: 36258030 PMCID: PMC9579163 DOI: 10.1038/s41598-022-22290-1] [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: 09/03/2022] [Accepted: 10/12/2022] [Indexed: 01/10/2023] Open
Abstract
This study aimed to assess the association between interpregnancy interval (IPI)-the time from childbirth to conception of the next pregnancy-and maternal and neonatal morbidity. The World Health Organization (WHO) currently recommends an IPI of at least 24 months after a live birth to reduce adverse birth outcomes. However, assessing the relationship between IPI and perinatal outcome is complicated by confounding factors. We conducted a nationwide population-based cohort study using Swedish registry data, allowing for adjustment of maternal characteristics and health at first birth. The study population consisted of all women with a singleton, live, and vaginal first birth with a second singleton birth within five years during 1997-2017, covering 327,912 women and 655,824 neonates. IPI was grouped into six-month intervals with 24-29 months as the reference. The association between IPI and morbidity was examined using multivariate logistic regression. For women having a vaginal delivery at their first birth, intervals < 24-29 months were associated with decreased maternal morbidity and unaffected neonatal morbidity. Intervals > 24-29 months were associated with increased maternal and neonatal morbidity. Our findings question the relevance of WHO's recommendation of an IPI of at least 24 months in a high-income country.

Abstract
Prophylactic antibiotic usage during delivery is a common practice worldwide, especially in low- to middle-income countries. Guidelines have been published to reduce antibiotic overuse; however, data describing the use of prophylactic antibiotics and clinician adherence to guidelines in low- to middle-income countries remain limited. This study aimed to describe the prevalence of prophylactic antibiotic use, factors associated with its use, and clinician adherence to guidelines. A retrospective review was conducted for all deliveries from 1 January 2016 to 31 December 2018 at a tertiary level hospital in Indonesia. The prevalence of prophylactic antibiotic use during delivery was 47.1%. Maternal education level, Ob/Gyn specialist-led delivery, a history of multiple abortions, C-section, premature membrane rupture, and antepartum hemorrhage were independently associated with prophylactic antibiotic use. Clinician adherence to the guidelines was 68.9%. Adherence to guidelines was the lowest in conditions where the patient had only one indication for prophylactic antibiotics (aOR 0.36, 95% CI 0.24-0.54). The findings showed that the prevalence of prophylactic antibiotic use during delivery was moderate to high. Adherence to local guidelines was moderate. Updating the local prescribing guidelines may improve clinician adherence.

[PMID: 33430833 PMCID: PMC7802326 DOI: 10.1186/s12884-020-03528-0] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2020] [Accepted: 12/26/2020] [Indexed: 11/22/2022] Open
Abstract
Background In recent years, first-trimester intrauterine hematoma (IUH) has become increasingly common in twin pregnancy. The majority of studies on IUH have excluded twin pregnancies, and others did not differentiate between singleton and twin pregnancies. The impact of IUH on twin pregnancy is unclear. Therefore, the primary objective of our study was to examine associations between first-trimester IUH and pregnancy outcomes in twin pregnancies. Methods The data of 1020 twin pregnancies in women who received a routine examination from January 2014 to December 2018 were reviewed. We compared baseline data and pregnancy outcomes between those with and without IUH. Multivariable logistic regression analysis was used to adjust for possible confounding factors. Results A total of 209 patients (21.3%) developed IUH in the first trimester. First-trimester IUH was significantly associated with increased odds of miscarriage (adjusted odds ratio 14.27, 95% CI 8.25–24.70) and vanishing twin syndrome (adjusted odds ratio 3.26, 95% CI 1.11–4.61). However, there were no differences in the rates of stillbirth, preeclampsia, preterm labor (< 34 weeks), low birth weight, postpartum hemorrhage or fetal distress between the two groups. Maternal age, previous preterm birth, chorionicity in twins and the gestational week at first ultrasound did not differ between the two groups. The women with IUH had high rates of previous miscarriage (46.73% vs 38.37%, p = 0.01), assisted conception (48.56% vs 32.60%, p < 0.001) and accompanied vaginal bleeding (67.46% vs 13.43%, p < 0.001). According to the logistic regression analyses, these characteristics were not associated with pregnancy loss or vanishing twin syndrome. No IUH characteristics, including volume, largest diameter, or the presence of vaginal bleeding, were associated with pregnancy loss or vanishing twin syndrome before 20 weeks of gestation (P > 0.05). Conclusion In women with twin pregnancy, the presence of IUH in the first trimester was associated with the loss of one or both fetuses before 20 weeks of gestation. However, previous miscarriage, the conception method, the IUH size and the presence of vaginal bleeding were not independently associated with miscarriage or vanishing twin syndrome.

Pregnancy-Related Complications in Women with Recurrent Pregnancy Loss: A Prospective Cohort Study. J Clin Med 2020; 9:jcm9092833. [PMID: 32882985 PMCID: PMC7564138 DOI: 10.3390/jcm9092833] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2020] [Revised: 08/31/2020] [Accepted: 08/31/2020] [Indexed: 12/16/2022] Open
Abstract
The aim of this prospective cohort study was to determine whether women with recurrent pregnancy loss (RPL) have an increased risk of pregnancy complications compared to normal pregnant women. A total of 1092 singleton pregnancies were followed, 431 in women with RPL and 661 in normal healthy women. The prevalence of the following complications was observed: threatened miscarriage, miscarriage, cervical insufficiency, chromosomal/genetic abnormalities, fetal anomalies, oligohydramnios, polyhydramnios, fetal growth restriction, intrauterine fetal death, gestational diabetes mellitus (GDM), preeclampsia, placenta previa, abruptio placentae, pregnancy-related liver disorders, and preterm premature rupture of the membranes. The odds ratio and 95% CI for each pregnancy complication considered were determined by comparing women with RPL and normal healthy women. Women with RPL had an overall rate of pregnancy complications higher than normal women (OR = 4.37; 95% CI: 3.353–5.714; p < 0.0001). Their risk was increased for nearly all the conditions considered. They also had an increased risk of multiple concomitant pregnancy complications (OR = 4.64; 95% CI: 3.10–6.94, p < 0.0001). Considering only women with RPL, women with ≥3 losses had a higher risk of pregnancy complications than women with two losses (OR = 1.269; 95% CI: 1.112–2.386, p < 0.02). No differences were found in the overall risk of pregnancy complications according to the type, explained or unexplained, of RPL. Women with secondary RPL had an increased risk of GDM than women with primary RPL. Pregnancy in women with RPL should be considered at high risk.

Linehan LA, Morris AG, Meaney S, O'Donoghue K. Subsequent pregnancy outcomes following second trimester miscarriage-A prospective cohort study. Eur J Obstet Gynecol Reprod Biol 2019; 237:198-203. [PMID: 31071653 DOI: 10.1016/j.ejogrb.2019.04.006] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2019] [Revised: 04/01/2019] [Accepted: 04/05/2019] [Indexed: 11/24/2022]
Abstract
OBJECTIVES Pregnancy after second-trimester miscarriage represents as clinical challenge. This study sought to determine the rates of recurrence, preterm birth and live births in a cohort of 185 women with previous second-trimester miscarriage. We hypothesized that there would be a higher rate of second-trimester miscarriage and preterm birth in subsequent pregnancy after second trimester miscarriage. The primary objectives of this study were to establish rates of second-trimester miscarriage, preterm birth and live births in this cohort. Secondary objectives were to examine medical and surgical interventions, in addition to other pregnancy outcomes and complications. STUDY DESIGN This was a prospective cohort study carried out in a tertiary referral center in southern Ireland with over 8000 deliveries per year. 175 women were followed up. Inclusion criteria were an ultrasound confirmed second-trimester miscarriage between June 2009 and June 2013 and subsequently having a pregnancy between July 2009 and January 2016. Fifty-five women did not become pregnant during the study period and were excluded. Ten women were excluded for missing data. RESULTS Between July 2009 and January 2016, 110 women became pregnant following a previous second-trimester miscarriage. In total, 81 babies were born to 77 mothers. The recurrence rate of second-trimester miscarriage was 6.3% (7/110) and the preterm birth rate was also 6.3% (7/110). The cesarean section rate was 45%. Including those who experienced first or second trimester miscarriage, 47% (78/155) of those who were followed up did not go on to have a live infant. CONCLUSIONS Women experiencing second-trimester miscarriage are at increased risk in subsequent pregnancies of recurrence. Second-trimester miscarriage needs to be highlighted as a risk factor for adverse pregnancy outcomes. Greater research into its pathophysiology is required to advance preventative measures.

[PMID: 30700492 PMCID: PMC6352763 DOI: 10.1136/bmjopen-2018-027941] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/16/2018] [Revised: 11/23/2018] [Accepted: 11/23/2018] [Indexed: 01/02/2023] Open
Abstract
INTRODUCTION Short interpregnancy interval (IPI) has been linked to adverse pregnancy outcomes. WHO recommends waiting at least 2 years after a live birth and 6 months after miscarriage or induced termination before conception of another pregnancy. The evidence underpinning these recommendations largely relies on data from low/middle-income countries. Furthermore, recent epidemiological investigations have suggested that these studies may overestimate the effects of IPI due to residual confounding. Future investigations of IPI effects in high-income countries drawing from large, population-based data sources are needed to inform IPI recommendations. We aim to assess the impact of IPIs on maternal and child health outcomes in high-income countries. METHODS AND ANALYSIS This international longitudinal retrospective cohort study will include more than 18 million pregnancies, making it the largest study to investigate IPI in high-income countries. Population-based data from Australia, Finland, Norway and USA will be used. Birth records in each country will be used to identify consecutive pregnancies. Exact dates of birth and clinical best estimates of gestational length will be used to estimate IPI. Administrative birth and health data sources with >99% coverage in each country will be used to identify maternal sociodemographics, pregnancy complications, details of labour and delivery, birth and child health information. We will use matched and unmatched regression models to investigate the impact of IPI on maternal and infant outcomes, and conduct meta-analysis to pool results across countries. ETHICS AND DISSEMINATION Ethics boards at participating sites approved this research (approval was not required in Finland). Findings will be published in peer-reviewed journals and presented at international conferences, and will inform recommendations for optimal IPI in high-income countries. Findings will provide important information for women and families planning future pregnancies and for clinicians providing prenatal care and giving guidance on family planning.

Abstract
Problem Several studies have reported the increased risk of preterm birth, premature rupture of membranes, and low birth weight in patients with recurrent pregnancy loss (RPL). There have been a limited number of large population‐based studies examining adverse pregnancy and perinatal outcome after RPL. Multiple‐imputed analyses (MIA) adjusting for biases due to missing data is also lacking. Method of study A nationwide birth cohort study known as the “Japan Environment and Children’s Study (JECS)” was conducted by the Ministry of the Environment. The subjects consisted of 104 102 registered children (including fetuses or embryos). Results No increased risk of a congenital anomaly, aneuploidy, neonatal asphyxia, or a small for date infant was observed among the children from women with a history of RPL. A novel increased risk of placental adhesion and uterine infection was found. The adjusted ORs using MIA in women with three or more PL were 1.76 (95% CI, 1.04‐2.96) for a stillbirth, 1.68 (1.12‐2.52) for a pregnancy loss, 2.53 (1.17‐5.47) for placental adhesion, 1.87 (1.37‐2.55) and 1.60 (.99‐2.57) for mild and severe hypertensive disorders of pregnancy, respectively, 1.94 (1.06‐3.55) for uterine infection, 1.28 (1.11‐1.47) for caesarean section and .86 (.76‐.98) for a male infant. Conclusion MIA better quantified the risk, which could encourage women who might hesitate to attempt a subsequent pregnancy.

Abstract
PurposeTo determine the association of maternal factors and exposure during pregnancy with the incidence in newborns of epibulbar dermoid (ED), a congenital ocular surface benign tumor.Patients and methodsThis is a retrospective, paired case-control study in which 121 children with ED (case group) and 121 children without ED (control group) were recruited. Questionnaire-based interviews with mothers of participants were performed and maternal medical records during pregnancy were reviewed. The questionnaire investigated basic information, personal history, environmental exposure, exposure to maternal diseases, symptoms and corresponding medical treatments during pregnancy, and parental socioeconomic status. The case and control participants were matched for sex, birth weight, gestational age, and parental socioeconomic status level. Univariate and multivariate logistic regression analyses were conducted with ED as the main outcome variable.ResultsFactors significantly associated with ED were: history of maternal inevitable miscarriage (odds ratio (OR), 2.59; 95% confidence intervals (CI), 1.13-5.90), common cold in the first trimester (OR, 3.94; CI, 1.74-8.93), and paternal smoke exposure >half a pack per day during pregnancy (OR, 4.81; CI, 1.74-13.28).ConclusionHistory of maternal miscarriage, common cold exposure in the first trimester, and paternal smoking (>half a pack per day) during pregnancy could result in significant risk factors for ED of newborns. These data also imply that paternal smoking delivers nicotine to maternal respiratory system and uterine microenvironment that may both affect microvascular development and predispose the fetus to future ED.

Abstract
The aim of this study was to examine if women with history of recurrent miscarriage have a higher risk of maternal and foetal complications in future pregnancies. This was a retrospective case control study that analysed data collected prospectively between 2001 and 2007 from 400 women with history of recurrent miscarriage who achieved pregnancies progressing beyond 24 weeks gestation compared to 39,860 deliveries from the general obstetric database within the same time period. Results showed that women with recurrent miscarriage had significantly increased odds of low Apgar scores at one (odds ratios (OR) 1.57, 95% CI 1.20-2.05) and five minutes (OR 2.0, 95% CI 1.23-3.27), small for gestational age (OR 1.96, 95% CI 1.12-3.43), preterm delivery (OR 1.64, 95% CI 1.22-2.19) and antepartum haemorrhage (OR 7.67, 95% CI 4.23-13.91). The risks were increased in the presence of a male foetus but no difference was observed between primary and secondary miscarriage patients. In conclusion, women with recurrent miscarriage have an increased risk of several maternal and foetal complications and therefore may require closer monitoring during the antenatal period particularly when pregnant with a male foetus.

Abstract
Ethnic minorities living in the US have lower utilization and access to prenatal care, resulting in an increased risk of adverse pregnancy outcomes. The present study examines utilization of prenatal care, perceived pregnancy related health, and perceived risk of adverse pregnancy outcomes among Arab women living in the USA cross-sectional study was conducted, consisting of a convenience sample of 170 Arab women. A structured questionnaire was administered by a face-to-face or telephone interview. Multivariable logistic regression was used to calculate adjusted Odds Ratios and 95% Confidence Intervals, controlling for potential confounders. All study participants had received prenatal care during their most recent pregnancy, and 90% had their first prenatal care visit before the 12th gestational week. The Arab women who were older (P = 0.02), those with 12 years of education or less (P = 0.002), and those who had lived in the US more than five years (P = 0.0002) were more likely to report four or more pregnancies. In addition, more than one-third of the women reported having experienced a miscarriage (35.4%), which was significantly associated with gravida status (P < 0.001). An association between perceived susceptibility for spontaneous abortion and stillbirth was also demonstrated (P < 0.0001). Although Arab women reported good coverage of prenatal care, they perceived themselves as susceptible for several pregnancy complications and adverse pregnancy outcomes. Clinical guidelines for prenatal care to Arab women should therefore focus on their high parity and likelihood of miscarriages, in an attempt to reduce their risk of adverse pregnancy outcomes.

Abstract
BACKGROUND Approximately 15-20% of all clinically confirmed pregnancies end in a miscarriage. Intrauterine adhesions (IUAs) are a possible complication after miscarriage, but their prevalence and the contribution of possible risk factors have not been elucidated yet. In addition, the long-term reproductive outcome in relation to IUAs has to be elucidated. METHODS We systematically searched the literature for studies that prospectively assessed the prevalence and extent of IUAs in women who suffered a miscarriage. To be included, women diagnosed with a current miscarriage had to be systematically evaluated within 12 months by hysteroscopy after either spontaneous expulsion or medical or surgical treatment. Studies that included women with a history of recurrent miscarriage only or that evaluated the IUAs after elective abortion or beyond 12 months after the last miscarriage were not included. Subsequently, long-term reproductive outcomes after expectant (conservative), medical or surgical management were assessed in women with and without post-miscarriage IUAs. RESULTS We included 10 prospective studies reporting on 912 women with hysteroscopic evaluation within 12 months of miscarriage and 8 prospective studies, including 1770 women, reporting long-term reproductive outcome. IUAs were detected in 183 women, resulting in a pooled prevalence of 19.1% [95% confidence interval (CI): 12.8-27.5%]. The extent of IUAs was reported in 124 women (67.8%) and was mild, moderate and severe respectively in 58.1, 28.2 and 13.7% of cases. Relative to women with one miscarriage, women with two or three or more miscarriages showed an increased risk of IUAs by a pooled OR of 1.41 and 2.1, respectively. The number of dilatation and curettage (D&C) procedures seemed to be the main driver behind these associations. A total of 150 congenital and acquired intrauterine abnormalities were encountered in 675 women, resulting in a pooled prevalence of 22.4% (95% CI: 16.3-29.9%). Similar reproductive outcomes were reported subsequent to conservative, medical or surgical management for miscarriage, although the numbers of studies and of included women were limited. No studies reported long-term reproductive outcomes following post-miscarriage IUAs. CONCLUSIONS IUAs are frequently encountered, in one in five women after miscarriage. In more than half of these, the severity and extent of the adhesions was mild, with unknown clinical relevance. Recurrent miscarriages and D&C procedures were identified as risk factors for adhesion formation. Congenital and acquired intrauterine abnormalities such as polyps or fibroids were frequently identified. There were no studies reporting on the link between IUAs and long-term reproductive outcome after miscarriage, while similar pregnancy outcomes were reported subsequent to conservative, medical or surgical management. Although this review does not allow strong clinical conclusions on treatment management, it signals an important clinical problem. Treatment strategies are proposed to minimize the number of D&C in an attempt to reduce IUAs.

Abstract
PURPOSE OF REVIEW To evaluate the impact of early pregnancy complications involving placentation and early placental development on adverse obstetric outcome in ongoing and subsequent pregnancies. RECENT FINDINGS We found an increased risk of adverse outcome (odds ratio >2.0) in ongoing pregnancies of preterm delivery (PTD), very preterm delivery (VPTD), placental abruption, small for gestational age (SGA), low birth weight (LBW) and very LBW (VLBW) after a threatened miscarriage episode; pregnancy-induced hypertension, preeclampsia, placental abruption, PTD, SGA and low 5-min Apgar score following the detection of an intrauterine haematoma; and VPTD, VLBW and perinatal death after a vanishing twin phenomenon. In subsequent pregnancies, the risk of perinatal death was increased (odds ratio >2.0) after a single miscarriage, the risk of VPTD after two or more miscarriages, the risk of placenta previa, premature preterm rupture of membranes, PTD, VPTD and LBW after recurrent miscarriage and the risk of VPTD after two or more terminations of pregnancy. SUMMARY Our analysis of the literature review indicates a link between early pregnancy complications involving the placenta and subsequent adverse obstetric and perinatal outcomes. Some of these associations are based on limited or small uncontrolled studies. Larger population-based prospective controlled studies have recently been published confirming most of these findings. This suggests that the early detection of these risk factors could improve the screening of women at high risk of specific obstetric complications in ongoing and subsequent pregnancies.

Abstract
OBJECTIVE This study was performed to determine whether second-trimester pregnancy loss was associated with an increased risk for spontaneous preterm birth or recurrent second-trimester loss in a subsequent pregnancy. STUDY DESIGN A retrospective cohort study was conducted. Patients with a second-trimester pregnancy loss (n = 38), a spontaneous preterm birth (n = 76), and a full term delivery (n = 76) were identified from 2002 to 2005 (index pregnancy). Computerized medical records were used to obtain demographic and obstetrical histories. RESULTS Frequencies of subsequent second-trimester loss were 27%, 3%, and 1% in the second-trimester loss, spontaneous preterm birth, and full-term delivery cohorts, respectively. Frequencies of subsequent spontaneous preterm birth were 33%, 39.5%, and 9% in the same 3 cohorts. Patients with a prior second-trimester loss were 10.8 times more likely to have recurrent second-trimester loss or spontaneous preterm birth, compared with those with prior full-term delivery (confidence interval 3.6 to 32.1, P < .0001). CONCLUSION Patients with a prior second-trimester loss are at significantly increased risk for spontaneous preterm birth and recurrent second-trimester loss in their next pregnancy.

Abstract
OBJECTIVE To quantify the risk of placenta praevia and placental abruption in singleton, second pregnancies after a caesarean delivery of the first pregnancy. DESIGN Retrospective cohort study. SETTING Linked birth and infant mortality database of the USA between 1995 and 2000. POPULATION A total of 5,146,742 singleton second pregnancies were available for the final analysis after excluding missing information. METHODS Multiple logistic regressions were used to describe the relationship between caesarean section at first birth and placenta praevia and placental abruption in second-birth singletons. MAIN OUTCOME MEASURES Placenta praevia and placental abruption. RESULTS Placenta praevia was recorded in 4.4 per 1000 second-birth singletons whose first births delivered by caesarean section and 2.7 per 1000 second-birth singletons whose first births delivered vaginally. About 6.8 per 1000 births were complicated with placental abruption in second-birth singletons whose first births delivered by caesarean section and 4.8 per 1000 birth in second-birth singletons whose first births delivered vaginally. The adjusted odds ratio (95% CIs) of previous caesarean section for placenta praevia in following second pregnancies was 1.47 (1.41, 1.52) after controlling for maternal age, race, education, marital status, maternal drinking and smoking during pregnancy, adequacy of prenatal care, and fetal gender. The corresponding figure for placental abruption was 1.40 (1.36, 1.45). CONCLUSION Caesarean section for first live birth is associated with a 47% increased risk of placenta praevia and 40% increased risk of placental abruption in second pregnancy with a singleton.

Abstract
Women with a history of reproductive loss may be at an increased risk of having an unfavourable outcome in subsequent pregnancies. Using data from a matched case-control study based on the record of the Epidemiological Surveillance System of Neural Tube Defects, we evaluated the association between history of maternal reproductive loss and the risk of anencephaly in three Mexican states. Mothers of 157 cases of anencephaly and 151 controls born during the period March 2000 to February 2001, were interviewed about their reproductive history and other additional factors, including socio-economic characteristics, prenatal care, use of tobacco and alcohol, presence of chronic diseases, acute illnesses and fever during the periconceptional period, and consumption of multivitamins and medicines during this period; mothers who reported no prior pregnancies were excluded from the analysis; 58 matched case-control pairs were used for the analysis. After adjusting for potential confounders, women with a history of miscarriage in previous pregnancies had 4.58 times more risk of having a child with anencephaly, than those who did not have this history; OR = 4.58, [95% CI 1.22, 17.23]. Our results suggest that a history of previous miscarriages is a risk indicator for anencephaly in future gestations. This does not necessarily mean that the miscarriage itself is the cause, but that common mechanisms could be involved in the aetiology of both events. Thus, women who have had histories of reproductive losses, especially miscarriages, should be a priority group for the primary and secondary prevention of neural tube defects.

Abstract
OBJECTIVE To determine the pregnancy outcome following a previous spontaneous abortion (miscarriage). METHOD A prospective cohort study was done on 300 gravida-2 patients: 200 patients (case group) whose previous pregnancy was spontaneously aborted (early abortion), and 100 patients (control group) whose previous pregnancy went to term and a live fetus was delivered. All the patients were followed until delivery, and then the pregnancy outcomes, neonatal complications and delivery routes were determined and compared between the 2 groups. Pregnancy outcomes included: maternal complications (e.g. placenta previa, placental abruption, premature rupture of the membranes, preeclampsia and eclampsia, abortion, breech presentation, preterm labor, intrauterine fetal death); neonatal complications (low birth weight, gross congenital malformations, low Apgar score at 1 min), and delivery routes (cesarean delivery or instrumental delivery, e.g. forceps or vacuum). Statistical analysis was performed using the Statistical Package for Social Science. RESULTS Statistical analysis showed that the pregnancy complications following a previous spontaneous miscarriage were no different from those of the control group, except for abortion (16.5 vs. 11%, p < 0.003, RR = 1.15, CI 95% = 0.95-1.39), fetal deaths (1.5 vs. 0%, p < 0.004, RR = 1.51, CI 95% = 1.39-1.63), and vaginal bleeding during the first trimester (19 vs. 1%, p < 0.001, RR = 1.57, CI 95% = 1.41-1.75), which were more than those of the control group. Also, the rate of cesarean delivery (28.14 vs. 13.48%) was increased (p = 0.026, RR = 1.25, CI 95% = 1.07-1.47). Neonatal complications were not statistically significantly different in comparison with the control group. CONCLUSION A prior spontaneous miscarriage is a risk for the next pregnancy, and the risk of abortion and intrauterine fetal death will increase. Therefore, careful prenatal care is mandatory.

Abstract
BACKGROUND We hypothesized that stress induced by the terrorist attacks of September 11, 2001 might shorten pregnancy. To test this hypothesis, we compared gestational duration and risk of preterm delivery among women who were pregnant on September 11 with women who had delivered before that date. STUDY DESIGN We conducted a matched cohort study among pregnant women enrolled in the Boston-based cohort study Project Viva between 1999 and 2001. Each of 606 participants, pregnant on September 11, 2001, was matched to 1 or 2 participants who delivered before that date. RESULTS Compared with women who delivered before September 11th, women who were pregnant on September 11th had mean gestation length that was 0.13 weeks longer (95% confidence interval = -0.05 to 0.30) and an odds ratio for preterm delivery before 37 weeks' gestation of 0.60 (0.36 to 0.98). Only women exposed in the first trimester had longer gestation. CONCLUSIONS Contrary to expectation, Boston-area women who were pregnant on September 11th had a lower risk of preterm delivery than women who delivered before that date. Although the interpretation of this finding is difficult, it is clear that the acute psychologic stress documented nationwide after the terrorist attacks did not increase the risk of preterm delivery in this population at some distance from the attacks.

Abstract
Embryotoxic factors existing in maternal sera may influence their effects via specific binding to, or alteration of cell surface molecules in the conceptus. This study was undertaken to determine the effects of sera from women with unexplained recurrent spontaneous abortion (URSA) on cell surface glycoconjugates of the early conceptus. Four cell stage embryos were cultured in medium supplemented with sera from women with URSA, from normal women, or in medium without serum. Developmental competence was assessed as the stage distribution of embryos advancing to during 96h in culture. Hatched (expanded) blastocysts were stained with wheat germ agglutinin (WGA), peanut agglutinin (PNA) and dolichos biflorus agglutinin (DBA) to detect surface glucoconjugates. We observed that patient sera could be divided into high- and low-risk groups on the basis of the ability to decrease the number of four-cell embryos reaching the expanded blastocyst stage. Furthermore, the intensity of reactivity to PNA changed after exposure to high-risk sera. Morula formation was reduced and blastocyst formation was delayed. Although the sera from women with URSA had embryotoxic effects, no influence on the glycoconjugate patterns were evident in hatched blastocysts, aside from PNA reactivivity. We suggest altered developmental display of PNA-reactive proteins was a biomarker for poor developmental quality due to emrbyotoxic factors in serum from URSA patients.

Abstract
OBJECTIVES The purpose of this study was to examine the association between previous pregnancy losses and subsequent risk of preterm delivery. STUDY DESIGN A population-based Swedish study including information on all births and women's hospital admissions for pregnancy loss (n = 601,883) in Sweden between 1987 and 2000 was performed. The risk of preterm delivery after a previous pregnancy loss was estimated using logistic regression models. The risk of preterm premature ruptures of the membranes (PROM), preterm labor, and other reasons for preterm delivery was also assessed. RESULTS Previous spontaneous abortions and missed abortions were associated with increased risks of preterm delivery, and the risks increased with severity of preterm delivery. Previous pregnancy loss increased the risk of preterm PROM and preterm labor foremost in deliveries before 32 weeks, but was not associated with other reasons of very preterm delivery. CONCLUSION Our results support the hypothesis that pregnancy loss and early preterm delivery may share etiologic causes.

Abstract
OBJECTIVE To evaluate the association between maternal reproductive history and preterm delivery. METHODS The 312 preterm delivery cases, studied in aggregate, and in subgroups (spontaneous preterm labor, preterm premature rupture of membranes, medically induced preterm delivery, moderate preterm delivery [gestational age at delivery 34-36 weeks], and very preterm delivery [gestational age at delivery <34 weeks]), were compared with 424 randomly selected women who delivered at term. Maternal medical records provided information on maternal reproductive history, pregnancy outcome, as well as sociodemographic characteristics. Using multivariate logistic regression, we derived maximum likelihood estimates of adjusted odds ratios (OR) and 95% confidence intervals (CI). RESULTS A history of 2+ miscarriages was (OR = 2.2; 95% CI 1.2-3.9), but a history of 2+ prior induced abortions (OR = 1.2; 95% CI 0.7-2.0) was not, associated with preterm delivery in the index pregnancy. Analyses of preterm delivery subgroups indicated that a history of 2+ miscarriages was associated with an increased risk of spontaneous preterm labor (OR = 2.6; 95% CI 1.2-2.8), preterm premature rupture of membrane (OR = 1.8; 95% 0.7-4.4), and medically induced preterm delivery (OR = 1.9; 95% CI 0.8-4.2), though only the former approached statistical significance. Excess risk of preterm delivery was associated with maternal prior history of delivering a stillborn infant (OR = 10.7), a prior history of delivering a newborn that later died during the neonatal period (OR = 3.2), and a prior history of having a pregnancy complicated by spontaneous preterm delivery (OR = 6.0). Generally these associations were evident for each subgroup of preterm delivery, though inferences were often hindered by our relatively small sample size. CONCLUSIONS These results support the hypothesis that maternal adverse reproductive history is associated with an increased risk of preterm labor and delivery.

Abstract
Gestational-hypertension/pre-eclampsia occurs in approximately 10% of human pregnancies. This persistent complication of pregnancy has been reported to occur more frequently in couples conceiving very shortly after the beginning of their sexual relationship and/or after a change in paternity. Primipaternity may be the leading cause of pre-eclampsia in women under 30 years of age when genetic susceptibility to cardio-vascular disease has not yet been expressed, especially in women before their twenties, who for the last 40,000 years have perhaps comprised the age group when the majority of parturients classified as Homo sapiens sapiens initiated their reproductive life. In terms of evolution, the prevalence of pre-eclampsia represents a distinct reproductive disadvantage in humans as compared with other mammals. Indeed, pre-eclampsia is a consequence of the defect of the normal human-specific deep endovascular invasion of the trophoblast. The large size of the human fetal brain imposing this deep trophoblastic invasion induced the need for major immunogenetic compromises in terms of paternal-maternal tissue tolerance. The price that mankind has had to pay to adapt to the pre-eclampsia risk is a low fecundability rate and therefore loss of oestrus, possibly a step in the deviation between apes and hominids. Further, pre-eclampsia risk may be a contributing factor leading to the rejection of systematic polyandry in human societies and have influenced prohibition of incest.

Abstract
Our objective was to study birthweight among surviving siblings in families with and without a perinatal loss, and to evaluate whether different causes of death were associated with the results. Data were for 1967-98 from the Norwegian Medical Birth Registry. Births were organised with the mother as the observation unit through the personal identification number, providing sibship files. We analysed 550 930 sibships with at least two singletons, 208 586 sibships with at least three singletons and 45 675 sibships with at least four singleton births. We compared mean birthweight and gestational age between infants in sibships with and without a perinatal loss, total losses and the different causes of death. Surviving siblings in families with a perinatal loss had significantly lower mean birthweights than their counterparts in unaffected families, after adjusting for gestational age, interpregnancy interval, time period and marital status. An exception was found when cause of death was a birth defect, when growth retardation among surviving siblings was not found on average. We conclude that families who have lost an infant because of a birth defect do not appear to have an increased risk of adverse birth outcome associated with growth restriction.

Abstract
OBJECTIVE The aim of this study was to evaluate the clinical condition at birth and some laboratory parameters in newborns of mothers treated for recurrent spontaneous abortion (RSA) of unknown etiology with paternal lymphocytes immunization. STUDY DESIGN The study comprised 104 newborns delivered by 102 women with RSA, who underwent alloimmunization and 90 randomly chosen control newborns. The following parameters were analysed in two groups of newborns: general condition at birth, physical development, course of adaptation period, values of hematological and immunological (percentage of CD3, CD4, CD8, CD19 and CD3/CD25 lymphocytes, chemiluminescence of neutrophils at rest and stimulated with opsonized zymosane) parameters in umbilical arterial blood. RESULTS No statistically significant differences were noted between the two groups of newborns as to the duration of pregnancy, birth weight, general condition at birth, occurrence of complications in the adaptation period and values of studied hematological and immunological parameters. CONCLUSION These results suggest that immunization with paternal lymphocytes in women with RSA of unknown etiology not only creates better prognosis for the outcome of the pregnancy, but is also safe for the fetus and the newborn.

Abstract
In this study, an assessment of normal mouse allantoic development and its sensitivity to 2'-(R)-deoxycoformycin (dCF; Pentostatin) exposure were examined. Both dissecting microscopy and scanning electron microscopy were used to describe the normal growth and morphogenesis of the mouse allantois over gestational days 7-10 as a preliminary step in evaluating potential abnormal allantoic ontogeny and its effect on umbilical cord and placental development. Two abnormal allantoic/umbilical cord phenotypes were observed subsequent to injecting pregnant mice with 5 mg dCF/kg, i.p., on gestational day 7 (GD 7) and evaluating litters on GD 10, 11, and 12. Abnormal phenotypes included: (1) an allantois which extended approximately halfway across the exocoelom but failed to establish a functional contact with the chorion; and (2) a phenotype characterized by reduced expansion of the allantois across the chorionic surface, a very thin umbilical cord, and aberrant vascularization throughout the structure. Both abnormal phenotypes exhibited either an agenesis or hypogenesis of the umbilical cord and chorioallantoic plate, respectively. Neither abnormal phenotype, however, exhibited errors in the directionality of allantoic growth toward the chorion nor in the formation of aberrant contacts between allantois and adjacent yolk sac or amnionic mesenchyme. Statistical interpretation of the experimental data strongly suggested that abnormalities in allantoic/umbilical cord development were directly associated with embryolethality as evidenced by a decline in the frequency of abnormal allantoic/umbilical cord phenotypes over GD 10-12 (73, 36, and 4%; respectively) and a concomitant increase in the frequency of implantation site resorptions over the same time period (7, 47, and 78%). These results strongly suggest that the developing allantois is very sensitive to the effects of dCF exposure, and that interference with its development leads to embryolethality by GD 12.

Abstract
The objective of this study was to identify important risk factors for spontaneous abortion (SA) among Saudi women. It was a case-control study conducted at King Khalid University Hospital, Riyadh, Saudi Arabia. The cases were 226 consecutive women hospitalized for SA between October 1992 and January 1993. The controls were 226 consecutive women who had normal delivery in the same hospital during the same period. Bivariate analysis using chi-square tests and estimates of relative risks indicated a positive association of age at menarche with risk of SA (P < 0.01). Also, there was a significant higher risk of SA when a women was married to a blood related husband than if married to a non relative (RR = 2.1). The number of previous abortions was also positively related to the risk of SA in the current pregnancy (P < 0.01). Compared to primigravidas, the risk of SA was 3.2 times greater than if the outcome of the most recent pregnancy was also an SA. Other factors that had significant bivariate association with SA were a family history of SA, abdominal trauma, and infection during pregnancy. When multiple logistic regression was used to adjust for the effects of confounding variables, all the factors that showed significant bivariate association with SA (except outcome of the last pregnancy) remained significant. Early menarche may be protective, but further study is needed to confirm this. Greater attention should be given to pregnant women who had personal or family history of SA and those who had trauma and/or infection during pregnancy. Premarital counselling concerning consanguineous marriages is recommended.

Abstract
A preliminary case-control study was conducted on Saudi women to detect possible risk factors for spontaneous abortion (SA). Two hundred and twenty six consecutive women hospitalised for SA and 226 women admitted for normal delivery and used as controls, were studied. Women with SA were significantly older at menarche (Relative Risk (RR) = 3.2), more frequently married to blood-related husbands (RR = 2.1) and husbands older than 50 years (RR = 2.4). Number of previous abortions related linearly to the risk of aborting spontaneously in the next pregnancy. Compared to primigravidas, the RR was 3.2 if the outcome of the most recent pregnancy was SA, and 0.8 if it was a livebirth. A family history of SA was more common among cases (RR = 4.6). Spontaneous abortion was also associated with daily consumption of more than 150 mg of caffeine, abdominal trauma, infection and fever during pregnancy. No significant association, however, emerged with maternal age, social class, education, exposure to video display terminals, parity, use of contraception, diabetes or obesity. The application of these data in clinical practice and future research needs are discussed.

Abstract
OBJECTIVE To look for associations between previous fetal loss and fetal malformation or low birthweight in a subsequent pregnancy. DESIGN A case-control study with place of birth, time and sex matched controls. SETTING 72 South American maternity hospitals. SUBJECTS 18,534 malformed, 1150 non-malformed babies of low birthweight and 16,394 controls. All babies were from mothers with at least one previous pregnancy. MAIN OUTCOME MEASURES Frequency of stillbirths and miscarriages in the previous pregnancy and outcome of the index pregnancy. RESULTS Multiple malformation, Down's syndrome, anencephaly, spina bifida, pes equinovarus, congenital dislocation of the hip and low birthweight are associated with previous fetal loss. CONCLUSION A miscarriage or a stillbirth in a previous pregnancy should be taken into account when the risk of malformations or low birthweight in a subsequent pregnancy is assessed.
