Accurate estimate of fetal maturity could provide individualized guidance for delivery of complicated pregnancies. However, current methods are invasive, have low accuracy, and are limited to fetal lung maturation. To identify diagnostic gestational biomarkers, we performed transcriptomic profiling of lung and brain, as well as cell-free RNA from amniotic fluid of preterm and term rhesus macaque fetuses. These data identify potentially new and prior-associated gestational age differences in distinct lung and neuronal cell populations when compared with existing single-cell and bulk RNA-Seq data. Comparative analyses found hundreds of genes coincidently induced in lung and amniotic fluid, along with dozens in brain and amniotic fluid. These data enable creation of computational models that accurately predict lung compliance from amniotic fluid and lung transcriptome of preterm fetuses treated with antenatal corticosteroids. Importantly, antenatal steroids induced off-target gene expression changes in the brain, impinging upon synaptic transmission and neuronal and glial maturation, as this could have long-term consequences on brain development. Cell-free RNA in amniotic fluid may provide a substrate of global fetal maturation markers for personalized management of at-risk pregnancies.

Objective Although the Accreditation Council for Graduate Medical Education and American Board of Pediatrics (ABP) provide regulations and guidance on fellowship didactic education, each program establishes their own didactic schedules to address these learning needs. Wide variation exists in content, educators, amount of protected educational time, and the format for didactic lectures. This inconsistency can contribute to fellow dissatisfaction, a perceived poor learning experience, and poor attendance. Our objective was to create a Neonatal–Perinatal Medicine (NPM) fellow curriculum based on adult learning theory utilizing fellow input to improve the perceived fellow experience. Study Design A needs assessment of current NPM fellows at Cincinnati Children's Hospital was conducted to guide the development of a new curriculum. Fellow perception of educational experience and board preparedness before and after introduction of the new curriculum was collected. Study period was from October 2018 to July 2021. Results One hundred percent of the fellows responded to the needs assessment survey. A response rate of 100 and 87.5% were noted on mid-curriculum survey and postcurriculum survey, respectively. Key themes identified and incorporated into the curriculum included schedule structure, content, and delivery mode. A new didactic curriculum implementing a consistent schedule of shorter lectures grouped by organ system targeting ABP core content was created. After curriculum implementation, fellows had higher self-perception of board preparedness, and overall improved satisfaction. Conclusion Our positive experience in implementing this curriculum provides a framework for individual programs to implement similar curricula, and could be utilized to aid in development of national NPM curricula. Key Points Fellowship didactic education varies significantly resulting in learner dissatisfaction and poor attendance. Widespread need to restructure didactic curricula exists. Our study provides a framework for future curricula. [ABSTRACT FROM AUTHOR]

Children born prematurely have greater lifetime risk for hypertension. We aimed to determine (1) the association between prematurity and cardiovascular disease (CVD) risk factors among 90 children with obesity and elevated blood pressure and (2) if dietary sodium intake modified these associations. Multivariable regression analysis explored for associations between prematurity (<37 weeks gestation; early gestational age) and low birth weight (<2.5 kg) with hypertension, left ventricular mass index (LVMI), and left ventricular hypertrophy (LVH). Effect modification by dietary sodium intake was also explored. Patients were predominately male (60%), black (78%), adolescents (13.3 years), and with substantial obesity (body mass index: 36.5 kg/m2). Early gestational age/low birth weight was not an independent predictor for hypertension, LVMI, or LVH. There was no effect modification by sodium load. Our results suggest the increased CVD risk conferred by prematurity is less significant at certain cardiometabolic profiles. Promoting heart-healthy lifestyles to prevent pediatric obesity remains of utmost importance to foster cardiovascular health. [ABSTRACT FROM AUTHOR]

The past decade has been notable for widespread dissemination of newborn resuscitation training in low-resource settings through simplified training programs including Helping Babies Breathe. Since 2020, implementation efforts have been impacted by restrictions on travel and in-person gatherings with the SARS-CoV-2 pandemic, prompting the development of alternative methods of training. While previous studies have demonstrated feasibility of remote neonatal resuscitation training, this perspective paper covers common barriers identified and key lessons learned developing a cadre of remote facilitators. Challenges of remote facilitation include mastering videoconferencing platforms, establishing personal connections, and providing effective oversight of skills practice. Training sessions can be used to support facilitators in acquiring comfort and competency in harnessing videoconferencing platforms for effective facilitation. Optimization of approaches and investment in capacity building of remote facilitators are imperative for effective implementation of remote neonatal resuscitation training. [ABSTRACT FROM AUTHOR]

To evaluate the impact of neonatal resuscitation and basic obstetric care on intrapartum-related neonatal mortality in low and middle-income countries, using the mathematical model, Maternal and Neonatal Directed Assessment of Technology (MANDATE). Using MANDATE, we evaluated the impact of interventions for intrapartum-related events causing birth asphyxia (basic neonatal resuscitation, advanced neonatal care, increasing facility birth, and emergency obstetric care) when implemented in home, clinic, and hospital settings of sub-Saharan African and India for 2008. Total intrapartum-related neonatal mortality (IRNM) was acute neonatal deaths from intrapartum-related events plus late neonatal deaths from ongoing intrapartum-related injury. Introducing basic neonatal resuscitation in all settings had a large impact on decreasing IRNM. Increasing facility births and scaling up emergency obstetric care in clinics and hospitals also had a large impact on decreasing IRNM. Increasing prevalence and utilization of advanced neonatal care in hospital settings had limited impact on IRNM. The greatest improvement in IRNM was seen with widespread advanced neonatal care and basic neonatal resuscitation, scaled-up emergency obstetric care in clinics and hospitals, and increased facility deliveries, resulting in an estimated decrease in IRNM to 2.0 per 1,000 live births in India and 2.5 per 1,000 live births in sub-Saharan Africa. With more deliveries occurring in clinics and hospitals, the scale-up of obstetric care can have a greater effect than if modeled individually. Use of MANDATE enables health leaders to direct resources towards interventions that could prevent intrapartum-related deaths. A lack of widespread implementation of basic neonatal resuscitation, increased facility births, and emergency obstetric care are missed opportunities to save newborn lives.

The objectives of this study is to evaluate the impact of vital record gestational age estimation method on resulting preterm birth (PTB) rate calculations. This retrospective analysis reviewed three methods of gestational age estimation using all Ohio live birth records from 2006 to 2009. PTB rates were calculated using each gestational age representation and agreement between classifications of PTB was evaluated with respect to maternal age and race. For each of 608,530 births, gestational age estimates based on last menstrual period (LMP) were compared to clinically-based obstetric estimates. When gestational age estimates did not perfectly agree, differences in the consequential classification of PTB status were evaluated with respect to a third reconciliatory combined gestational age estimate. Mean birth weight at each week of gestation was calculated and compared for all three estimate methods. Substantial agreement was found in PTB classification among gestational age estimates (kappa: 0.748; 95% Confidence Interval: 0.745-0.750); agreement was weakest among black mothers and among mothers less than 20 years of age. LMP-based gestational age estimates did not perfectly agree with obstetric estimates in 238,262 records (39.2%). Disagreement in gestational age led to disagreement in PTB status in 32,033 records (5.3% of total cases) resulting in a 1.8 percentage point difference in PTB rate calculations (11.0% using obstetric and 12.8% using combined estimates). Researchers and policy makers need consistency in selecting which gestational age estimate method to use when calculating or comparing PTB rates.
