Risk of adverse perinatal outcomes among women with pharmacologically treated and untreated depression during pregnancy: A retrospective cohort studyby Adhikari et al
This study examined the risks of adverse perinatal outcomes associated with antidepressant use during pregnancy. Both depression and antidepressant use were independently associated with the risk of adverse perinatal outcomes; however, the risk associated with antidepressants was higher over and above the risk associated with depression. This may reflect the biological effects of antidepressants, greater severity of depression in those treated, or both.
Does facility birth reduce maternal and perinatal mortality in Brong Ahafo, Ghana? A secondary analysis using data on 119 244 pregnancies from two cluster-randomised controlled trialsby Gabrysch et al
This study is a secondary analysis of surveillance data on 119 244 pregnancies from two large population-based cluster-randomised controlled trials in Brong Ahafo, Ghana. Findings suggest that facility birth does not necessarily convey a survival benefit for women or babies and should only be recommended in facilities capable of providing emergency obstetric and newborn care and capable of safe-guarding uncomplicated births.
Effect of Addition of an Intimate Partner Violence Intervention to a Nurse Home Visitation Program on Maternal Quality of Life A Randomized Clinical Trialby Jack et al
This cluster randomised trial assessed whether augmentation of a nurse home visitation program with an intimate partner violence intervention, starting in pregnancy, compared with the home visitation program alone, leads to improved maternal quality of life at 24 months after infant delivery? The trial included 492 pregnant women, randomization to the augmented program compared with nurse home visitation alone resulted in maternal quality-of-life scores at 24 months postdelivery of 311.3 vs 316.2 (measured using the WHOQOL-BREF scale; range, 0-400)—a difference that was not statistically significant. These findings do not support augmenting a nurse home visitation program with this complex, multifaceted intimate partner violence intervention.
Inherited predisposition to stillbirth: an intergenerational analysis of 26,788 mother-daughter pairsby Woolner AMF et al
The aim of the study was to investigate if there is an inherited predisposition to stillbirth transmitted from mother to daughter. The findings suggest that among the daughters, 384 had a history of one or more stillbirths (cases) while 26,404 only ever had livebirths (controls). We found no statistically significant association between mothers' history of stillbirth (adjusted Odds Ratio (aOR) 0.63; 95% CI 0.24-1.63) or miscarriage (aOR 1.01; 95% CI 0.71-1.42) and stillbirth in daughters.
Perinatal outcomes in twin pregnancies complicated by maternal morbidity: evidence from the WHO Multicountry Survey on Maternal and Newborn Healthby Santana et al
The objective of the preset study is to evaluate perinatal outcomes associated with twin pregnancies, stratified by severe maternal morbidity and order of birth. Secondary analysis of the WHO Multicountry Survey on Maternal and Newborn Health (WHOMCS), a cross-sectional study implemented in 29 countries. Data from 8568 twin deliveries were compared with 308,127 singleton deliveries. The occurrence of adverse perinatal outcomes and maternal complications were assessed. Factors independently associated with adverse perinatal outcomes were reported with adjusted PR (Prevalence Ratio) and 95%CI. Findings suggest that twin pregnancy is significantly associated with severe maternal morbidity and with worse perinatal outcomes, especially for the second twin.
Burden of physical, psychological and social ill-health during and after pregnancy among women in India, Pakistan, Kenya and Malawiby McCauley et al
For every woman who dies during pregnancy and childbirth, many more suffer ill-health, the burden of which is highest in low-resource settings. The study sought to assess the extent and types of maternal morbidity. Findings from this study suggests that women suffer significant ill-health which is still largely unrecognised. Current antenatal and postnatal care packages require adaptation if they are to meet the identified health needs of women.
The authors performed a systematic review and meta-analysis that evaluated the prophylactic effect of aspirin during pregnancy. Sixteen trials including 18,907 participants provided data for preterm and term preeclampsia. Findings suggest that Aspirin reduces the risk of preterm preeclampsia but not term preeclampsia, and only when it is initiated at ≤16 weeks of gestation and at a daily dose of ≥100 mg.
Measuring women’s childbirth experiences: a systematic review for identification and analysis of validated instrumentsby Nilver et al
Women’s childbirth experience can have immediate as well as long-term positive or negative effects on their life, well-being and health. When evaluating and drawing conclusions from research results, women’s experiences of childbirth should be one aspect to consider. Researchers and clinicians need help in finding and selecting the most suitable instrument for their purpose. The aim of this study was therefore to systematically identify and present validated instruments measuring women’s childbirth experience. This systematic review provides an overview of existing instruments measuring women’s childbirth experiences and can support researchers to identify appropriate instruments to be used, and maybe adapted, in their specific contexts and research purpose.
This themed review brings together NIHR research on different aspects of health before, during and after pregnancy. It features:
- 46 published studies
- 28 ongoing studies or interim results
- Questions for clinicians, commissioners, public health professionals and othe
Customised and Noncustomised Birth Weight Centiles and Prediction of Stillbirth and Infant Mortality and Morbidity: A Cohort Study of 979,912 Term Singleton Pregnancies in Scotlandby Iliodromiti et al
This is a population-based linkage study of 979,912 term singleton pregnancies in Scotland, United Kingdom, between 1992 and 2010. At term, birth weight remains strongly associated with the risk of stillbirth and infant death and neonatal morbidity. Partial customisation does not improve prediction performance. Consideration of early term delivery or closer surveillance for those with a predicted birth weight ≤25th or ≥85th centile may reduce adverse outcomes. Replication of the analysis with fully customised centiles accounting for ethnicity is warranted.
Young adolescent girls are at high risk for adverse pregnancy outcomes in sub-Saharan Africa: an observational multicountry studyby Mombo-Ngoma et al
This study assessed whether young adolescent girls constitute a group at increased risk for adverse birth outcomes among pregnant women in sub-Saharan Africa. Young maternal age increases the risk for adverse pregnancy outcomes and it is a stronger predictor for low birth weight and preterm delivery than other established risk factors in sub-Saharan Africa. This finding highlights the need to improve adolescent reproductive health in sub-Saharan Africa.

Strategy for Standardization of Preeclampsia Research Study Design
Biobanks provide an important repository of samples for research purposes. However, for those samples to reflect the in vivo state, and for experimental reliability and reproducibility, careful attention to collection, processing and storage is essential.
Contraceptive use before first pregnancy by women in India (2005–2006): determinants and differentialsby Pandey et al 2015
This study attempts to identify the socio demographic determinants and differentials of contraceptive use or non use by a woman in India, before she proceeds to have her first child. The analysis was done using data from the third National Family Health Survey (2005–2006), India.
The Early Childhood Obesity Prevention Program (ECHO): an ecologically-based intervention delivered by home visitors for newborns and their mothersby Cloutier et al
The goals of the Early Childhood Obesity Prevention Program (ECHO) are to examine the 12-month efficacy of a primary obesity prevention program targeting the first year of life that is delivered by home visitors and that engages mothers as agents of change to modify their own behavior and their infant’s behavior through education and skill-building around nutrition, physical activity, and wellness, and then “echoes” her training with linkages to neighborhood programs and resources. ECHO will provide important information about whether an enhanced behavior change curriculum integrated into an existing home visitation program, focused on the mother as the agent of change and linked to neighborhood resources is effective in changing energy balance behaviors in the infant and in the mother. If effective, the intervention could be widely disseminated to prevent obesity in young children.
Does the type of abortion provider influence contraceptive uptake after abortion? An analysis of longitudinal data from 64 health facilities in Ghanaby Maxwell et al
The objectives of this study were to estimate the relationship between the type of abortion provider (consultant physician, house officer, or midwife) and two separate outcomes: (1) the likelihood of adopting postabortion contraception; (2) postabortion contraceptors’ likelihood of receiving a long-acting and permanent versus a short-acting contraceptive method.
Childhood acute lymphoblastic leukemia (ALL) can often be traced to a pre-leukemic clone carrying a prenatal genetic lesion. Postnatally acquired mutations then drive clonal evolution toward overt leukemia. The enzymes RAG1-RAG2 and AID, which diversify immunoglobulin-encoding genes, are strictly segregated in developing cells during B lymphopoiesis and peripheral mature B cells, respectively. Here we identified small pre-BII cells as a natural subset with increased genetic vulnerability owing to concurrent activation of these enzymes. Consistent with epidemiological findings on childhood ALL etiology, susceptibility to genetic lesions during B lymphopoiesis at the transition from the large pre-BII cell stage to the small pre-BII cell stage was exacerbated by abnormal cytokine signaling and repetitive inflammatory stimuli. We demonstrated that AID and RAG1-RAG2 drove leukemic clonal evolution with repeated exposure to inflammatory stimuli, paralleling chronic infections in childhood.
Stillbirth is strongly related to impaired fetal growth. However, the relationship between fetal growth and stillbirth is difficult to determine because of uncertainty in the timing of death and confounding characteristics affecting normal fetal growth. The study authors conducted a population-based case–control study of all stillbirths and a representative sample of live births in 59 hospitals in five geographic areas in the US. The study found that stillbirth is associated with both growth restriction and excessive fetal growth. These findings suggest that, contrary to current practices and recommendations, stillbirth prevention strategies should focus on both severe SGA and severe LGA pregnancies.
With an under-five mortality rate of 89 per 1000 live births, Pakistan is lagging behind the desired MDG 4. There is still a need to reduce the under-five mortality rate by 45 percentage points in order to achieve the MDG target by 2015. Each year around 91,000 and 53,300 children die from pneumonia and diarrhea respectively, in Pakistan. Diarrhea, pneumonia and malaria collectively contribute to around 50% of deaths in children. These three diseases, thus, represent a challenging but surmountable obstacle towards achieving the MDG 4 target. Implementation of large-scale interventions and scale-up plan focusing on these three major killers of children in Pakistan is essential. This report identifies the major barriers towards accessing essential medicines by care givers.
The Effect of Intermittent Antenatal Iron Supplementation on Maternal and Infant Outcomes in Rural Viet Nam: A Cluster Randomised Trialby Jai K Das
Anemia affects over 500 million women, and in pregnancy is associated with impaired maternal and infant outcomes. Intermittent antenatal iron supplementation is an attractive alternative to daily dosing; however, the impact of this strategy on infant outcomes remains unclear. This study compared the effect of intermittent antenatal iron supplementation with daily iron supplementation on maternal and infant outcomes in rural Viet Nam.
