A transcriptomic comparison of in vitro models of the human placenta.

Introduction: Selecting an in vitro culture model of the human placenta is challenging due to representation of different trophoblast cell types with distinct biological roles and limited comparative studies that define key characteristics of these models. The aim of this research was to compare the transcriptomes of common in vitro models of the human placenta compared to bulk human placental tissue.

Methods: We performed differential gene expression analysis on publicly available transcriptomic data from 7 in vitro models of the human placenta (HTR-8/SVneo, BeWo, JEG-3, JAR, Primary Trophoblasts, Villous Explants, and Trophoblast Stem Cells) and compared to bulk placental tissue from 2 cohort studies (CANDLE and GAPPS) or individual trophoblast cell types derived from bulk placental tissue.

Transcriptomic comparison of in vitro models of the human placenta.

Studying the human placenta through in vitro cell culture methods is necessary due to limited access and amenability of human placental tissue to certain experimental methods as well as distinct anatomical and physiological differences between animal and human placentas. Selecting an in vitro culture model of the human placenta is challenging due to representation of different trophoblast cell types with distinct biological roles and limited comparative studies that define key characteristics of these models. Therefore, the aim of this research was to create a comprehensive transcriptomic comparison of common in vitro models of the human placenta compared to bulk placental tissue from the CANDLE and GAPPS cohorts (N=1083).

At-Risk Newborns: Overlooked in Expansion From Essential Newborn Care to Small and Sick Newborn Care in Low- and Middle-Income Countries.

We propose adding the category of “at-risk” newborns for babies who are at increased risk of morbidity and/or mortality but do not require special or intensive care or monitoring to promote a 3-tiered newborn care approach in hospitals.

Placental transcriptomic signatures of spontaneous preterm birth.

Background: Spontaneous preterm birth accounts for most preterm births and leads to significant morbidity in the newborn and childhood period. This subtype of preterm birth represents an increasing proportion of all preterm births when compared with medically indicated preterm birth, yet it is understudied in omics analyses. The placenta is a key regulator of fetal and newborn health, and the placental transcriptome can provide insight into pathologic changes that lead to spontaneous preterm birth.

Prediction of gestational age using urinary metabolites in term and preterm pregnancies.

Assessment of gestational age (GA) is key to provide optimal care during pregnancy. However, its accurate determination remains challenging in low- and middle-income countries, where access to obstetric ultrasound is limited. Hence, there is an urgent need to develop clinical approaches that allow accurate and inexpensive estimations of GA.

Early prediction of preeclampsia in pregnancy with cell-free RNA.

Liquid biopsies that measure circulating cell-free RNA (cfRNA) offer an opportunity to study the development of pregnancy-related complications in a non-invasive manner and to bridge gaps in clinical care. Here we used 404 blood samples from 199 pregnant mothers to identify and validate cfRNA transcriptomic changes that are associated with preeclampsia, a multi-organ syndrome that is the second largest cause of maternal death globally. We find that changes in cfRNA gene expression between normotensive and preeclamptic mothers are marked and stable early in gestation, well before the onset of symptoms.

RNA profiles reveal signatures of future health and disease in pregnancy.

Maternal morbidity and mortality continue to rise, and pre-eclampsia is a major driver of this burden. Yet the ability to assess underlying pathophysiology before clinical presentation to enable identification of pregnancies at risk remains elusive. Here we demonstrate the ability of plasma cell-free RNA (cfRNA) to reveal patterns of normal pregnancy progression and determine the risk of developing pre-eclampsia months before clinical presentation.

Readiness to Provide Antenatal Corticosteroids for Threatened Preterm Birth in Public Health Facilities in Northern India.

Introduction: In 2014, the Government of India (GOI) released operational guidelines on the use of antenatal corticosteroids (ACS) in preterm labor. However, without ensuring the quality of childbirth and newborn care at facilities, the use of ACS in low- and middle-income countries is potentially harmful. This study assessed the readiness to provide ACS at primary and secondary care public health facilities in northern India.

Qualitative Assessment of the Quality of Care for Preterm, Low Birth Weight, and Sick Newborns in Ethiopia.

This study assesses the quality of care for preterm, low birth weight (LBW), and sick newborns across the public health care system levels in 3 regions of Ethiopia. Qualitative data based on the WHO framework to assess provision and experience of care was collected using in-depth interviews and focus group discussions with women who recently delivered preterm, LBW, and sick newborns, as well as health care providers and health extension workers, and facility administrators associated with study health facilities. This qualitative approach revealed perspectives of patients, health care providers and facility administrators to assess what is actually happening in facilities.

Assessment of feasibility and acceptability of family-centered care implemented at a neonatal intensive care unit in India.

Background: A family-centered care (FCC) parent participation program that ensures an infant is not separated from parents against their will was developed for the caring of their small or sick newborn at a neonatal intensive care unit (NICU) in Delhi, India. Healthcare provider sensitization training directed at psychosocial and tangible support and an audio-visual training tool for parent-attendants were developed that included: 1) handwashing, infection prevention, protocol for entry; 2) developmentally supportive care, breastfeeding, expression of breastmilk and assisted feeding; 3) kangaroo mother care; and 4) preparation for discharge and care at home. The study aimed to examine the feasibility and acceptability of the FCC model in a NICU in India.

Multiomics Characterization of Preterm Birth in Low- and Middle-Income Countries.

Importance: Worldwide, preterm birth (PTB) is the single largest cause of deaths in the perinatal and neonatal period and is associated with increased morbidity in young children. The cause of PTB is multifactorial, and the development of generalizable biological models may enable early detection and guide therapeutic studies.

Objective: To investigate the ability of transcriptomics and proteomics profiling of plasma and metabolomics analysis of urine to identify early biological measurements associated with PTB.

Implementing the Family-Led Care model for preterm and low birth weight newborns in Malawi: Experience of healthcare workers.

Background: Every Preemie-SCALE developed and piloted the Family-Led Care model, an innovative, locally developed model of care for preterm and low birth weight babies receiving kangaroo mother care.

Aim: The aim of this study was to describe healthcare workers' experience using Family-Led Care.

Setting: This study was conducted in five health facilities and their catchment areas in Balaka district, Malawi.

Referral systems for preterm, low birth weight, and sick newborns in Ethiopia: a qualitative assessment.

Background: A responsive and well-functioning newborn referral system is a cornerstone to the continuum of child health care; however, health system and client-related barriers negatively impact the referral system. Due to the complexity and multifaceted nature of newborn referral processes, studies on newborn referral systems have been limited. The objective of this study was to assess the barriers for effective functioning of the referral system for preterm, low birth weight, and sick newborns across the primary health care units in 3 contrasting regions of Ethiopia.

Health system readiness to support facilities for care of preterm, low birth weight, and sick newborns in Ethiopia: a qualitative assessment.

Background: Preterm birth is a worldwide challenge with the highest burden in low- and middle-income countries. Despite availability of low-cost interventions to decrease mortality of preterm, low birth weight, and sick newborns, these interventions are not well integrated in the health systems of low- and middle-income countries. The aim of this study was to assess, from the perspective of key stakeholders comprising leaders in the public health system, the health system readiness to support health care facilities in the care provided to preterm, low birth weight, and sick newborns in different regions of Ethiopia.

Sexually Transmitted Infections in Pregnancy and Reproductive Health: Proceedings of the STAR Sexually Transmitted Infection Clinical Trial Group Programmatic Meeting.

The goal of the STAR Sexually Transmitted Infection Clinical Trial Group (STI CTG) Programmatic meeting on Sexually Transmitted Infections (STIs) in Pregnancy and Reproductive Health in April 2018 was to review the latest research and develop recommendations to improve prevention and management of STIs during pregnancy. Experts from academia, government, nonprofit, and industry discussed the burden of STIs during pregnancy; the impact of STIs on adverse pregnancy and birth outcomes; interventions that work to reduce STIs in pregnancy, and the evidence, policy, and technology needed to improve STI care during pregnancy. Key points of the meeting are as follows: (i) alternative treatments and therapies for use during pregnancy are needed; (ii) further research into the relationship between the vaginal microbiome and STIs during pregnancy should be supported; (iii) more research to determine whether STI tests function equally well in pregnant as nonpregnant women is needed; (iv) development of new lower cost, rapid point-of-care testing assays could allow for expanded STI screening globally; (v) policies should be implemented that create standard screening and treatment practices globally; (vi) federal funding should be increased for STI testing and treatment initiatives supported by the Centers for Disease Control and Prevention (CDC), the Centers of Excellence in STI Treatment, public STD clinics, and the President's Emergency Plan for AIDS Relief (PEPFAR).

The Zambian Preterm Birth Prevention Study (ZAPPS): Cohort characteristics at enrollment.

Sub-Saharan Africa bears a disproportionate burden of preterm birth and other adverse outcomes. A better understanding of the demographic, clinical, and biologic underpinnings of these adverse outcomes is urgently needed to plan interventions and inform new discovery.  The Zambian Preterm Birth Prevention Study (ZAPPS) is a prospective observational cohort established at the Women and Newborn Hospital (WNH) in Lusaka, Zambia.

Antenatal Corticosteroids for Women at Risk of Imminent Preterm Birth in 7 sub-Saharan African Countries: A Policy and Implementation Landscape Analysis.

Background: Every year approximately 15 million babies are born prematurely and nearly 1 million die due to preterm birth complications. Evidence shows that antenatal corticosteroids (ACS) can be used to improve preterm birth outcomes in particular clinical settings. We conducted a policy and implementation landscape analysis of ACS use for women at risk of imminent preterm birth in 7 low-income countries.
