Review
BACKGROUND
Migration due to environmental factors is an international crisis affecting many nations globally. Pregnant people are a vulnerable subgroup of migrants.
AIM
This article explores the potential effects of environmental migration on pregnancy and aims to draw attention to this rising concern.
METHODS
Based on the study aim, a semi-structured literature review was performed. The following databases were searched: MEDLine (PubMed) and Google Scholar. The search was originally conducted on 31st January 2021 and repeated on 22nd September 2022.
RESULTS
Pregnant migrants are at increased risk of mental health disorders, congenital anomalies, preterm birth, and maternal mortality. Pregnancies exposed to natural disasters are at risk of low birth weight, preterm birth, hypertensive disorders, gestational diabetes, and mental health morbidity. Along with the health risks, there are additional complex social factors affecting healthcare engagement in this population.
CONCLUSION
Maternity healthcare providers are likely to provide care for environmental migrants over the coming years. Environmental disasters and migration as individual factors have complex effects on perinatal health, and environmental migrants may be at risk of specific perinatal complications. Obstetricians and maternity healthcare workers should be aware of these challenges and appreciate the individualised and specialised care that these patients require.

Observational Study
BACKGROUND
For women whose first pregnancy was complicated by pre-eclampsia (PE), particularly if severe and requiring early birth, the risk of recurrence and maternal and neonatal outcomes at subsequent birth are important considerations.
METHODS
In this observational cohort study, all primiparous women who gave birth in Denmark between 1997 and 2016 were identified using nationwide registries. Women were stratified by whether they developed PE and followed from date of birth until subsequent birth, emigration, death or end of study (December 2016). The cumulative incidences of subsequent birth among women with versus without PE were assessed using the Aalen-Johansen estimator. Subsequent outcomes including PE recurrence and maternal and neonatal morbidity and mortality were also examined. Factors associated with subsequent birth and recurrent PE were examined using multivariable Cox regression models.
RESULTS
Among 510 615 primiparous women with singleton pregnancies, 21 683 (4.2%) developed PE, with 1819 (0.4%) being early-onset PE (birth <34 weeks). Women with PE had a lower subsequent birth rate (57.4%) compared with women without PE (61.2%), and it was considerably lower among women with early-onset PE (49.4%). Among women with PE who had a subsequent birth, the overall recurrence rate of PE was 15.8% and higher among those with early-onset PE (31.5%). The gestational age increased with a median of 3 days (IQR -5 to 14) overall and 50 days (IQR 35-67) among those with early-onset PE. Moreover, neonatal and maternal morbidity and mortality were substantially improved in a subsequent pregnancy.
CONCLUSIONS
Primiparous women with PE have a significantly lower rate of a subsequent birth than women without PE, yet the absolute difference was modest. Although the overall risk of recurrent PE is 1 in 6, maternal and neonatal morbidity and mortality at subsequent birth are substantially improved.

Meta-Analysis Review
INTRODUCTION
The association between extreme birth spacing and adverse outcomes is controversial, and available evidence is fragmented into different classifications of birth spacing.
MATERIAL AND METHODS
We conducted a systematic review of observational studies to evaluate the association between birth spacing (i.e., interpregnancy interval and interoutcome interval) and adverse outcomes (i.e., pregnancy complications, adverse birth outcomes). Pooled odds ratios (ORs) with 95% confidence intervals (CI) were calculated using a random-effects model, and the dose-response relationships were evaluated using generalized least squares trend estimation.
RESULTS
A total of 129 studies involving 46 874 843 pregnancies were included. In the general population, compared with an interpregnancy interval of 18-23 months, extreme intervals (<6 months and ≥ 60 months) were associated with an increased risk of adverse outcomes, including preterm birth, small for gestational age, low birthweight, fetal death, birth defects, early neonatal death, and premature rupture of fetal membranes (pooled OR range: 1.08-1.56; p < 0.05). The dose-response analyses further confirmed these J-shaped relationships (p < 0.001-0.009). Long interpregnancy interval was only associated with an increased risk of preeclampsia and gestational diabetes (p < 0.005 and p < 0.001, respectively). Similar associations were observed between interoutcome interval and risk of low birthweight and preterm birth (p < 0.001). Moreover, interoutcome interval of ≥60 months was associated with an increased risk of cesarean delivery (pooled OR 1.72, 95% CI 1.04-2.83). For pregnancies following preterm births, an interpregnancy interval of 9 months was not associated with an increased risk of preterm birth, according to dose-response analyses (p = 0.008). Based on limited evidence, we did not observe significant associations between interpregnancy interval or interoutcome interval after pregnancy losses and risk of small for gestational age, fetal death, miscarriage, or preeclampsia (pooled OR range: 0.76-1.21; p > 0.05).
CONCLUSIONS
Extreme birth spacing has extensive adverse effects on maternal and infant health. In the general population, interpregnancy interval of 18-23 months may be associated with potential benefits for both mothers and infants. For women with previous preterm birth, the optimal birth spacing may be 9 months.

Human Reproduction (Oxford, England) Nov 2023Does the exposure to job loss during pregnancy increase the risk of miscarriage or stillbirth?
STUDY QUESTION
Does the exposure to job loss during pregnancy increase the risk of miscarriage or stillbirth?
SUMMARY ANSWER
The experience of own or partner's job loss during the pregnancy is associated with an increased risk of miscarriageand stillbirth.
WHAT IS KNOWN ALREADY
Prior research on the psycho-social aspect of pregnancy loss has investigated the contextual and the individual-level stressors. At the contextual level, natural disasters, air pollution, and economic downturns are associated with higher risk of pregnancy loss. At the individual level, intense working schedules and financial strain are linked with increased risk of pregnancy loss both at early and later stages of the gestation.
STUDY DESIGN, SIZE, DURATION
This work draws on high-quality individual data of 'Understanding Society', a longitudinal survey that has interviewed a representative sample of households living in the UK annually since 2009. Approximately 40 000 households were recruited. The analyses use all the available survey waves (1-12, 2009-2022).
PARTICIPANTS/MATERIALS, SETTING, METHODS
The final sample consisted of 8142 pregnancy episodes that contain complete informationon pregnancy outcome and date of conception. Ongoing pregnancies at the time of the interview were excluded from the final sample. The outcome variable indicated whether a pregnancy resulted in a live birth or a pregnancy loss whereas the exposure variable identified the women's or their partner's job loss because of redundancy or a dismissal. Logistic regression models were employed to estimate the relation between job loss during pregnancy and pregnancy loss. The models were adjusted for an array of socio-demographic and economic characteristics following a stepwise approach. Several sensitivity analyses complemented the main findings.
MAIN RESULTS AND THE ROLE OF CHANCE
Baseline models controlling for women's demographic background and prior experience of miscarriage estimated an increased risk of pregnancy loss when women were exposed to their own or their partner's job loss during their pregnancy (odds ratio (OR) = 1.99, 95% CI: 1.32, 2.99). When the models were adjusted for all socio-economic and partnership-related covariates the association remained robust (OR = 1.81, 95% CI: 1.20, 2.73).
LIMITATIONS, REASONS FOR CAUTION
First, the pregnancy outcome and the date of conception were self-reported and may besubjected to recall and social desirability bias. Second, although we adjusted for an array socio-demographic characteristics and self-reported health, other contextual factors might be correlated with both job loss and pregnancy loss. Third, owing to the limited sample size, we could not assess if the main finding holds across different socio-economic strata.
WIDER IMPLICATIONS OF THE FINDINGS
By showing that exposure to a job loss during pregnancy increases the risk of miscarriage and stillbirth, we underline the relevance of pregnancy loss as a preventable public health matter. This result also calls for policy designthat enhances labour market protection and social security buffers for pregnant women and their partners.

European Journal of Obstetrics,... May 2024To evaluate the association, if any, of homelessness or refuge accommodation on delivery and short term perinatal outcomes in an Irish tertiary maternity hospital.
OBJECTIVES
To evaluate the association, if any, of homelessness or refuge accommodation on delivery and short term perinatal outcomes in an Irish tertiary maternity hospital.
METHODS
A retrospective cohort study of 133 singleton pregnancies in women reporting to be homeless or living in refuge at their booking antenatal appointment between 2013 and 2022. Analysis compared sociodemographic characteristics and perinatal outcomes in this cohort to a reference population of 76,858 women with stable living arrangements.
RESULTS
Women in the homeless/refuge population were statistically more likely to be single (75.2 % vs 39.5 %, p < 0.001), have an unplanned pregnancy (73.7 % vs 27.2 %, p < 0.001), report a history of psychiatric illness (42.9 % vs 22.4 %, p < 0.001), domestic violence (18.8 % vs 0.9 %, p < 0.001) alcohol consumption in pregnancy (3.0 % vs 0.8 %, p < 0.001) or smoking in pregnancy (41.3 % vs 9.7 %, p < 0.001). They were significantly more likely to have a preterm birth (adjusted OR 1.71 (1.01-2.87) p = 0.04). They also had a significantly lower median birth weight compared to the reference population (birthweight 3270 g vs 3420 g, p < 0.001).
CONCLUSION
Women in the homeless and refuge population are more likely to experience poorer perinatal outcomes compared to women with stable living arrangements.

INTRODUCTION
Obesity in pregnancy is associated with adverse long-term consequences both in the mother and in offspring. Maternal obesity induces a metabolic-inflammatory state that could impact on placental function and could mediate the adverse outcomes. The purpose of this study was to compare the major placental histological characteristics of non-diabetic obese women to lean controls, focusing on uncomplicated pregnancies.
METHODS
Prospective case-control study comparing placental histopathological features between 122 non-diabetic obese women and 185 non-obese controls. The analysis was performed on overall subjects, then uncomplicated pregnancies from both groups were analyzed. Placenta pathologic findings were recorded according to standard classification.
RESULTS
Both in overall analysis and among the subset of subjects with an uncomplicated pregnancy, obese subjects had higher risks of maternal vascular malperfusion (MVM) (respectively OR=2.2, 95%CI =1.3-3.7 and OR=4.2, 95%CI=2.1-8.5), fetal vascular malperfusion (FVM) (respectively OR=6.3, 95%CI=3.1-12.5 and OR=7.2, 95%CI=3-17.2), maternal and fetal inflammatory response placental lesions and villitis (VUE) (respectively OR=2.5, 95%CI=1.1-5.6 and OR=10.8, 95%CI=3.3-35.3) compared to controls. Among uncomplicated pregnancies and after adjustment for confounders, first trimester BMI was significantly associated with overall MVM, overall FVM, maternal inflammatory, fetal inflammatory response and VUE.
DISCUSSION
Placentas from obese women showed a significantly higher risk of maternal and fetal vascular and inflammatory placental lesions, both in overall population and in the subgroup with uncomplicated pregnancies. The metabolic and inflammatory dysfunctions typical of obesity could have an impact on placental development and function, which could be a mediator of the detrimental effects of obesity on pregnancy outcome and on future health of the offspring.

Review
Risks associated with unintended pregnancy include unsafe abortions, poor maternal health-seeking behaviour, poor mental health, and potentially, maternal and infant deaths. Adolescent girls with unintended pregnancies are particularly vulnerable as they are at higher risk of eclampsia, premature onset of labour, and increased neonatal morbidity and mortality. Unintended pregnancy, with the right combination of interventions, can be avoided. Evidence-based decision-making and the need for a robust appraisal of the evidence have resulted in many systematic reviews. This review of systematic reviews focuses on adolescent pregnancy prevention and will seek to facilitate evidence-based decision-making. Two review authors independently extracted data and assessed the methodological quality of each review according to the AMSTAR 2 criteria. We identified three systematic reviews from low- and middle-income countries and high-income counties and included all socioeconomic groups. We used vote counting and individual narrative review summaries to present the results. Overall, skill-building, peer-led and abstinence programmes were generally effective. Interventions focused on information only, counselling and interactive sessions provided mixed results.In contrast, exposure to parenting and delaying sexual debut interventions were generally ineffective. Adolescent pregnancy prevention interventions that deploy school-based primary prevention strategies, i.e. strategies that prevent unintended pregnancies in the first place, may effectively reduce teenage pregnancy rates, improve contraceptive use, attitudes and knowledge, and delay sexual debut. However, the included studies have methodological issues, and our ability to generalise the result is limited.

OBJECTIVE
In this study, our pregnant systemic lupus erythematosus (SLE) cohort, which was under medical surveillance of both our Rheumatology and Obstetrics departments, was analyzed. We intended to determine the effects of pregnancy on disease activity and the correlation between disease flares and adverse pregnancy outcomes.
METHODS
One hundred sixty eight pregnancy data involving 136 patients with SLE were examined. Cumulative clinical, laboratory, and serological parameters were described. Disease activity and flares were calculated using the systemic lupus erythematosus disease activity index 2000 (SLEDAI-2K) in the pre/postpartum periods and the SLEPDAI in the three trimesters of pregnancy. Patients with a SLEDAI-2K or SLEPDAI ≥ 4 were classified as "active." Patients with lupus low disease activity state (LLDAS) during each of these periods were identified.Fetal/neonatal death, premature birth due to pre-eclampsia, eclampsia or hemolysis, elevated Liver enzymes (HELLP) syndrome, and neonates small for gestational age were determined as adverse pregnancy outcomes (APO).
RESULTS
Out of 168 pregnancies, there were 60 (35.7%) pregnancies with flares covering the pregnancy and 6 months of postpartum period. The mean SLEDAI in the 6 months postpartum period was significantly higher compared to mean disease activity during pregnancy ( < .05). Of all pregnancies, 132 (78.6%) were in LLDAS during pregnancy. Comparison of the frequency of severe postpartum flares in patients who were in LLDAS during pregnancy revealed a lower percentage of flares compared to those who were not in the LLDAS group (11 vs 29%, < .05). APO was observed in 33.9% of 168 pregnancies. The mean SLEPDAI score was significantly higher in APO+ pregnancies than in APO- pregnancies (4.9 ± 6.1 vs 2.8 ± 4.9, = .002). Comparison of SLICC damage score between APO - and + pregnancies revealed a significantly higher score in APO+ pregnancies (1.8 ± 2.1 vs 0.8 ± 1.3, = .001).
CONCLUSION
Postpartum six-month period appears to have the highest risk for disease flares during SLE pregnancies. Disease activity during pregnancy increases the risk of APO. In order to achieve a positive pregnancy outcome and lower maternal morbidity, regular follow-up of patients is necessary.

Unintended pregnancy is seen commonly in the family medicine setting. It is defined as a pregnancy that is mistimed (occurring sooner than wanted) or unwanted (not desired at that time or any time in the future). Approximately 45% of all US pregnancies are unintended. Childbirth resulting from an undesired pregnancy has been associated with adverse maternal and child health outcomes. Clinicians should be prepared to manage unplanned pregnancies, including dating pregnancies and discussing pregnancy options. Pregnancy options counseling entails discussing the options to parent, make an adoption plan, or undergo an abortion. Because of the complexity around pregnancy intentions, a framework that places patients at the center of their reproductive decisions and engages them in collaborative decision-making during options counseling is paramount. Patients commonly seek abortion, which is considered essential health care. Because of the current legal climate surrounding abortion in many states, patients may opt to use abortion drugs without licensed clinician oversight, called self-managed medication abortion, which has been shown to be safe and effective. No states require clinicians to report known or suspected self-managed medication abortion.

Pregnancy after stillbirth is associated with increased risk of stillbirth and other adverse pregnancy outcomes including fetal growth restriction, preeclampsia, and preterm birth in subsequent pregnancies. In addition, pregnancy after stillbirth is associated with emotional and psychological challenges for women and their families. This manuscript summarizes information available to guide clinicians for how to manage a pregnancy after stillbirth by appreciating the nature of the increased risk in future pregnancies, and that these are not affected by interpregnancy interval. Qualitative studies have identified clinician behaviors that women find helpful during subsequent pregnancies after loss which can be implemented into practice. The role of peer support and need for professional input from the antenatal period through to after the birth of a live baby is discussed. Finally, areas for research are highlighted to develop care further for this group of women at increased risk of medical and psychological complications.
