Risk of adverse infant outcomes associated with maternal mental health and substance use disorders

This study aimed to evaluate the association of mental health and substance use disorders on the risk of adverse infant outcomes overall and by race/ethnicity and payer. Given the risk of adverse infant outcomes associated with mental health and substance use disorders across racial/ethnic groups and payers, our findings highlight the critical importance of policies and clinical guidelines that support early identification and treatment of a broad spectrum of mental health and substance use disorders throughout the perinatal period.

Differences in Factors Associated With Preterm and Term Stillbirth: A Secondary Cohort Analysis of the DESiGN Trial

The objective of this study was to identify whether maternal and pregnancy characteristics associated with stillbirth differ between preterm and term stillbirth. Findings suggest that the differences in association exist between mothers experiencing preterm and term stillbirth. These differences could contribute to design of timely surveillance and interventions to further mitigate the risk of stillbirth.

Emergency Maternal Hospital Readmissions in the Postnatal Period: A Population-Based Cohort Stu

The objective of the study was to determine the change in English emergency postnatal maternal readmissions 2007-2017 (pre-COVID-19) and the association with maternal demographics, obstetric risk factors and postnatal length of stay (LOS). Findings suggest that the concerning rise in emergency maternal readmissions should be addressed from a health inequalities perspective focusing on women from minoritised ethnic groups; those <20 and ≥40 years old; primiparous women; and those with specified obstetric risk factors.

Postpartum haemorrhage and risk of cardiovascular disease in later life: A population-based record linkage cohort study

The objective of the study was to investigate the association between postpartum haemorrhage (PPH) and subsequent cardiovascular disease. Findings suggest that compared with women who have never had a PPH, women who have had at least one episode of PPH are twice as likely to develop cardiovascular disease in the first year after birth, and some increased risk persists for up to 15 years.

Maternal excessive weight gain as a potential risk factor for prolonged labor in Japanese pregnant women: The Japan Environment and Children's Study

This study aimed to determine whether excessive maternal weight gain during pregnancy was associated with a higher risk of prolonged labor. The overall incidence of prolonged labor was 10.2% (2,907/28,442) in nulliparous women and 6.1% (2,597/42,712) in multiparous women. Multivariable analysis indicated that excessive maternal weight gain was significantly associated with prolonged labor in nulliparous (adjusted odds ratio, 1.21; 95% confidence interval, 1.10-1.32) and multiparous women (adjusted odds ratio, 1.15; 95% confidence interval, 1.05-1.27). 

Involving men in pregnancy: a cross-sectional analysis of the role of self-efficacy, gender-equitable attitudes, relationship dynamics and knowledge among men in Kinshasa

This paper identified male involvement patterns during pregnancy and evaluated their associations with pregnancy and birth preparedness knowledge, gender-equitable attitudes, self-efficacy, and co-parental relationship factors. Lastly, it explored the moderating effect of gender-equitable attitudes and intimate partner violence on the association between relationship satisfaction and male involvement. The findings suggest that male involvement is multifaceted and factors influencing involvement vary depending on the type of involvement. Addressing these factors can improve male participation in maternal health.

Induction of labor versus expectant management among low-risk patients with one prior cesarean delivery

The objective of the study was to determine the association between clinical outcomes and induction of labor at 39 weeks in a national sample of low-risk patients with one prior cesarean delivery. Findings suggest that when compared to expectant management, elective induction of labor at 39 weeks in low-risk patients with one prior cesarean delivery was associated with a significantly higher likelihood of vaginal delivery with no difference in composite maternal and neonatal morbidity outcomes. Prospective studies are needed to better elucidate the risks and benefits of induction of labor in this patient population.

Effects of perineal massage at different stages on perineal and postpartum pelvic floor function in primiparous women: a systematic review and meta-analysis

Meta-analysis was used to evaluate the effect of implementing perineal massage in antenatal versus the second stage of labor on the prevention of perineal injuries during labor and early postpartum pelvic floor function in primiparous women. Findings suggest that Reducing perineal injuries in primiparous women can be achieved by providing perineal massage both antenatally and during the second stage of labor. Pelvic floor function is improved in the postnatal phase by perineal massage during the antenatal stage.

Uncovering the causes and socio-demographic constructs of stillbirths and neonatal deaths in an urban slum of Karachi

This study aims to investigate the causes and pathways leading to stillbirths and neonatal deaths in Rehri Goth to develop effective maternal and child health interventions. The study provides an opportunity to understand the causes of stillbirths and neonatal deaths in one of the impoverished slums of Karachi. The data segregation by clusters as well as triangulation with qualitative analysis highlight the needs of evidence-based strategies for maternal and child health interventions in disadvantaged communities.

Acetaminophen Use During Pregnancy and Children's Risk of Autism, ADHD, and Intellectual Disability

The objective of this stusy was to examine the associations of acetaminophen use during pregnancy with children's risk of autism, attention-deficit/hyperactivity disorder (ADHD), and intellectual disability. Findings suggest that acetaminophen use during pregnancy was not associated with children's risk of autism, ADHD, or intellectual disability in sibling control analysis. This suggests that associations observed in other models may have been attributable to familial confounding.

Neurodevelopmental Outcomes After Late Preterm Antenatal Corticosteroids: The ALPS Follow-Up Study

The Antenatal Late Preterm Steroids (ALPS) trial changed clinical practice in the United States by finding that antenatal betamethasone at 34 to 36 weeks decreased short-term neonatal respiratory morbidity. However, the trial also found increased risk of neonatal hypoglycemia after betamethasone. This follow-up study focused on long-term neurodevelopmental outcomes after late preterm steroids. In this follow-up study of a randomized clinical trial, administration of antenatal corticosteroids to persons at risk of late preterm delivery, originally shown to improve short-term neonatal respiratory outcomes but with an increased rate of hypoglycemia, was not associated with adverse childhood neurodevelopmental outcomes at age 6 years or older.

Two Randomized Trials of Low-Dose Calcium Supplementation in Pregnancy

The authors conducted two independent randomized trials of calcium supplementation, in India and Tanzania, to assess the noninferiority of a 500-mg daily dose to a 1500-mg daily dose of calcium supplementation. In each trial, the two primary outcomes were preeclampsia and preterm birth, and the noninferiority margins for the relative risks were 1.54 and 1.16, respectively.  In these two trials, low-dose calcium supplementation was noninferior to high-dose calcium supplementation with respect to the risk of preeclampsia. It was noninferior with respect to the risk of preterm live birth in the trial in India but not in the trial in Tanzania.

Reducing Severe Maternal Morbidity for Birthing Persons with Severe Hypertension through a Statewide Quality Improvement Initiative

The study aimed to assess the improvement in hospital care processes and patient outcomes associated with hypertensive disorders of pregnancy after introduction of a statewide Severe Maternal Hypertension quality improvement initiative. Findings suggest that introduction of a statewide quality improvement effort was associated with improved time-to-treatment of severe hypertension, as well as increased frequency of provider/nurse debriefs, appropriate patient education, and early postpartum follow up scheduled at discharge, and reduced severe maternal morbidity.

Cultural food practices and sources of nutrition information among pregnant and postpartum migrant women from low- and middle-income countries residing in high income countries: A systematic review

This systematic review explores the existing research on cultural food practices and sources of nutrition information among pregnant and postpartum migrant women from low- and middle-income countries (LMICs), residing in high-income countries. Findings suggest that there is a need for culturally appropriate nutrition education resources to guide pregnant migrants through healthy and harmful cultural food practices and overall nutrition during this crucial period.

When addressing resources is not enough: lessons learned from a respectful maternal and neonatal care provider training intervention evaluation in Kenya and Tanzania

MSI developed and implemented a hybrid training package, which includes an online module and 1-day in-person workshop that allows healthcare providers to explore their beliefs and attitudes towards Respectful Maternal and Neonatal Care (RMNC). It leverages methodologies used in Values-Clarification-Attitudes-Transformation (VCAT) workshops and behaviour change approaches. The results demonstrate that healthcare provider knowledge, attitudes and perceived RMNC practices can be improved with this training interventions. Patients also reported a more positive experience of their maternity care following the training.

Strategies for optimising early detection and obstetric first response management of postpartum haemorrhage at caesarean birth: a modified Delphi-based international expert consensus

This study aimed to develop an international expert’s consensus on evidence-based approaches for early detection and obstetric first response management of postpartum haemorrhage (PPH) intraoperatively and postoperatively in caesarean birth. Findings present the proposed agreed on approaches that could help improve the detection of PPH in the intraoperative and postoperative phases of caesarean birth and the first response management of intraoperative PPH. Determining how best to implement these strategies is a critical next step.

School-age Children and Adolescents Nutritional Survey (SCANS), Pakistan

SCANS was conducted in the province of Sindh and Punjab in Pakistan in the year 2020. The survey findings are crucial as it presents nutritional and health indicators from a large-scale survey to lay the foundation of future research aimed towards improving the health and lifestyle of children in the 5 – 10 years’ age group.

Sexual orientation disparities in adverse pregnancy outcomes

Sexual minority (SM) individuals experience poorer health outcomes than their heterosexual counterparts in various health domains and have health profiles—for example, health behaviors, experiences of healthcare discrimination, and limited resources owing to structural, interpersonal, and individual stigma—that may place them at higher risk for adverse pregnancy outcomes (APOs). However, little research has examined disparities in these outcomes with multidimensional measures of sexual orientation. 

Pregnancies complicated by bulimia nervosa are at increased risk of chorioamnionitis, anemia, and preterm birth

In this study, the authors aimed to investigate the risk for a wide array of adverse pregnancy outcomes among people with bulimia nervosa using an adjustment analysis to account for maternal confounding factors. Findings suggest that pregnant people with bulimia nervosa were at increased risk for a number of clinically important adverse live born pregnancy outcomes. Like others, however, we found no association with preterm birth overall, low birth weight, or small for gestational age.

RSV Prefusion F Protein-Based Maternal Vaccine - Preterm Birth and Other Outcomes

The authors conducted a phase 3 trial involving pregnant women 18 to 49 years of age to assess the efficacy and safety of RSVPreF3-Mat. The results of this trial, in which enrollment was stopped early because of safety concerns, suggest that the risks of any and severe medically assessed RSV-associated lower respiratory tract disease among infants were lower with the candidate maternal RSV vaccine than with placebo but that the risk of preterm birth was higher with the candidate vaccine.
