Post-war changes in the outcome of pregnancy in Maternity Hospital, Kuwait

Perinatal Data of Refugee Women from the Gynaecology Department of Charité University Hospital Berlin Compared with German Federal Analysis

Introduction The aim of this study was to record the perinatal data of refugee women at Charité Hospital, Berlin, and to evaluate possible differences in pre-, peri- and postnatal outcomes compared with indigenous women.

Material and Methods All pregnant women who gave birth in the period from 1 January 2014 to 30 September 2017 and were registered at least once in the hospital as “refugee” were included in the analysis. The data recorded from the refugee women were compared with the perinatal data of the German Federal obstetric analysis for the year 2016, which was published by the IQTIG (Institut für Qualitätssicherung und Transparenz im Gesundheitswesen [Institute for Quality Assurance and Transparency in Healthcare]).

Results The analysis comprised 907 refugee women and 928 infants (21 twin pregnancies). Pregnant refugee women were significantly younger than the pregnant women from the Federal analysis (birth before the age of 30: 66 vs. 41%, p < 0.001, RR: 1.6, 95% CI: 62.9 – 69.2). They had a history both of more pregnancies (≥ 3 pregnancies: 29.4 vs. 13.4%, p < 0.001, RR: 2.2, 95% CI: 26.4 – 32.5) and of more miscarriages (> 2 miscarriages: 9.7 vs. 5.9%, p < 0.001, RR: 1.6, 95% CI: 7.9 – 11.8) and more often had a history of suffering from psychological stress (11.1 vs. 4.1%, p < 0.001, RR: 2.70, 95% CI: 9.2 – 13.4). There were more premature births (10.3 vs. 3.0%, p < 0.001, RR: 3.36, 95% CI: 8.4 – 12.4), post-term pregnancies (8.5 vs. 0.5%, p < 0.001, RR: 15.4, 95% CI: 6.7 – 10.5), and cases of postpartum anaemia (28.7 vs. 22.0%, p < 0.001, RR: 1.30, 95% CI: 25.7 – 31.7) and puerperal endometritis (1 vs. 0.2%, p = 0.006, RR: 4.3, 95% CI: 0.5 – 1.9) compared with the Federal analysis. The neonatal outcome showed an increased rate of hypotrophy (11 vs. 7%, p < 0.001, RR: 1.6, 95% CI: 9.1 – 13.2), more stillbirths (0.7 vs. 0.2%, p = 0.006, RR: 3, 95% CI: 0.2 – 1.4) and increased congenital malformations (2.8 vs. 0.4%, p < 0.001, RR: 3, 95% CI: 0.2 – 1.4).

Conclusion Both refugee women and their infants showed significant differences. Despite the average younger age of the pregnant refugee women, the rates of premature birth and stillbirth and congenital malformations were significantly more frequent. More intensive antenatal screening with differentiated foetal organ diagnostics including psychosomatic care could contribute to early identification and prompt diagnosis. As regards the postpartum anaemia and puerperal endometritis, which occur more often in refugee women, midwife engagement and an improvement in the living situation in homes and accommodation facilities could be of great importance.

Conflict violence reduction and pregnancy outcomes: A regression discontinuity design in Colombia

BACKGROUND

The relationship between exposure to conflict violence during pregnancy and the risks of miscarriage, stillbirth, and perinatal mortality has not been studied empirically using rigorous methods and appropriate data. We investigated the association between reduced exposure to conflict violence during pregnancy and the risks of adverse pregnancy outcomes in Colombia.

METHODS AND FINDINGS

We adopted a regression discontinuity (RD) design using the July 20, 2015 cease-fire declared during the Colombian peace process as an exogenous discontinuous change in exposure to conflict events during pregnancy, comparing women with conception dates before and after the cease-fire date. We constructed the cohorts of all pregnant women in Colombia for each day between January 1, 2013 and December 31, 2017 using birth and death certificates. A total of 3,254,696 women were followed until the end of pregnancy. We measured conflict exposure as the total number of conflict events that occurred in the municipality where a pregnant woman lived during her pregnancy. We first assessed whether the cease-fire did induce a discontinuous fall in conflict exposure for women with conception dates after the cease-fire to then estimate the association of this reduced exposure with the risks of miscarriage, stillbirth, and perinatal mortality. We found that the July 20, 2015 cease-fire was associated with a reduction of the average number of conflict events (from 2.64 to 2.40) to which women were exposed during pregnancy in their municipalities of residence (mean differences -0.24; 95% confidence interval [CI] -0.35 to -0.13; p < 0.001). This association was greater in municipalities where Fuerzas Armadas Revolucionarias de Colombia (FARC) had a greater presence historically. The reduction in average exposure to conflict violence was, in turn, associated with a decrease of 9.53 stillbirths per 1,000 pregnancies (95% CI -16.13 to -2.93; p = 0.005) for municipalities with total number of FARC-related violent events above the 90th percentile of the distribution of FARC-related conflict events and a decrease of 7.57 stillbirths per 1,000 pregnancies (95% CI -13.14 to -2.00; p = 0.01) for municipalities with total number of FARC-related violent events above the 75th percentile of FARC-related events. For perinatal mortality, we found associated reductions of 10.69 (95% CI -18.32 to -3.05; p = 0.01) and 6.86 (95% CI -13.24 to -0.48; p = 0.04) deaths per 1,000 pregnancies for the 2 types of municipalities, respectively. We found no association with miscarriages. Formal tests support the validity of the key RD assumptions in our data, while a battery of sensitivity analyses and falsification tests confirm the robustness of our empirical results. The main limitations of the study are the retrospective nature of the information sources and the potential for conflict exposure misclassification.

CONCLUSIONS

Our study offers evidence that reduced exposure to conflict violence during pregnancy is associated with important (previously unmeasured) benefits in terms of reducing the risk of stillbirth and perinatal deaths. The findings are consistent with such beneficial associations manifesting themselves mainly through reduced violence exposure during the early stages of pregnancy. Beyond the relevance of this evidence for other countries beset by chronic armed conflicts, our results suggest that the fledgling Colombian peace process may be already contributing to better population health.

Activity of Paraoxonase/Arylesterase and Butyrylcholinesterase in Peripheral Blood of Gulf War Era Veterans With Neurologic Symptom Complexes or Post-Traumatic Stress Disorder

OBJECTIVE

Two groups of Gulf War era veterans, one exhibiting blurred vision, balance problems/dizziness, tremors/shaking, and speech difficulty and a second group with post-traumatic stress disorder (PTSD), but not the neurologic syndrome, were assessed for organophosphate-detoxifying enzyme paraoxonase/arylesterase (PON1) and its Q/R isoforms, butyrylcholinesterase (BuChE) and its U/A isoforms and cytokines.

METHODS

Defibrinated peripheral blood was evaluated for enzymes and cytokines.

RESULTS

Trends toward elevation of Th2 cytokines interleukin-4 (IL-4) and IL-13 were observed in subjects with neurologic syndrome. Neither the activities nor isoforms of the enzyme, the neurologic symptoms, nor PTSD had any relationship to wartime deployment to the theater of combat.

CONCLUSION

The negative outcomes described above suggest that exposure to organophosphates or other agents normally detoxified by PON1 and BuChE may not have contributed significantly to neurologic components of Gulf War Illness.

Adverse effects of exposure to armed conflict on pregnancy: a systematic review

Introduction

Exposure to armed conflict has manifold implications for both military and civilian populations. Prenatal stress has detrimental effects on both obstetric outcomes, fetal development and the development of an individual later in life. As well as causing stress to the mother, armed conflicts can decimate local infrastructures making it increasingly difficult to access antenatal and general healthcare. The present review is particularly salient in light of the many ongoing current conflicts. It examines the impacts of exposure to armed conflicts on the pregnancy outcomes.

Methods

A thorough literature search was carried out on three databases using MeSH and truncation terms. 13 studies were included in the final analysis relating to mothers exposed to armed conflicts since 1990.

Results

The studies include data from 1 172 151 patients: mothers from Libya, Bosnia, Herzegovina, Israel, Palestine, Kosovo, Yugoslavia, Nepal, Somalia, Iraq, Kuwait and Afghanistan. There is evidence of an increased risk of mothers giving birth to babies of low birth weight as reported in nine included studies. All have a degree of bias, with four at lower and five at higher risk of bias, either not adjusting for confounders or not employing robust measures of exposure to conflict. Further evidence suggested an increase in the incidence of miscarriage, stillbirth, prematurity, congenital abnormalities, miscarriage and premature rupture of membranes among mothers exposed to armed conflict.

Conclusion

Despite the varying degrees of bias which must be considered for the available evidence, the data with the lowest risk of bias suggest a relationship between exposure to armed conflict and low birth weight. In light of the current level of displacement experienced by such populations, the identification of pregnancies at risk could improve the efficacy of antenatal care. Clinicians should consider additional ultrasound scanning where appropriate to monitor for restricted growth in such pregnancies.

Mortality risk of small infants varies with their mother's birthweight and race

We analysed a transgenerational linked birth file to investigate the relationship between maternal birthweight and infant birthweight-specific mortality risk for white and African American infants. Birth records of 267,303 infants born between 1989 and 1991 were linked to records of their mothers, born between 1956 and 1976, and to their own death certificates for those dying in the first year. The means, standard deviations and z-scores were calculated for each race- and generation-specific birthweight distribution. Investigators then analysed the mortality of very small infants (birthweight at least two standard deviations below their mean) for three maternal birthweight categories. Over half of the infant deaths involved births with weights more than two standard deviations below the relevant population mean birthweight (comprising 4.2% of white and 6.9% of African American births respectively). African American infants experienced higher mortality rates at all levels of standardised birthweight, from z-scores of -3 to +3. The relative risk of mortality associated with very small infant size was less for infants delivered to smaller birthweight mothers when compared with those whose mothers were average sized or large at birth. This differential effect was confined to neonatal deaths and was more prominent in the white subpopulation.
