J Affect Disord 2021 Mar 31;287:406-416. Epub 2021 Mar 31.

Department of Epidemiology and Health Statistics, School of Public Health, Anhui Medical University, No. 81 Meishan Road, Hefei 230032, Anhui, China; Centre for Evidence-Based Practice, Anhui Medical University, No. 81 Meishan Road, Hefei 230032, Anhui, China. Electronic address:

Background: Stressful life events as important stressors have gradually been recognized as the potential etiology that may lead to adverse birth outcomes such as preterm birth (PTB), low birth weight (LBW), and small for gestational age (SGA). However, researches on this topic have shown relatively inconsistent results. This systematic review and meta-analysis was performed to synthesize available data on the association between prenatal stressful life events and increased risks of PTB, LBW, and SGA. Read More

Insights into intrauterine growth restriction based on maternal and umbilical cord blood metabolomics.

Sci Rep 2021 Apr 9;11(1):7824. Epub 2021 Apr 9.

Institute of Chemical Biology, National Hellenic Research Foundation, Athens, Greece.

Intrauterine growth restriction (IUGR) is a fetal adverse condition, ascribed by limited oxygen and nutrient supply from the mother to the fetus. Management of IUGR is an ongoing challenge because of its connection with increased fetal mortality, preterm delivery and postnatal pathologies. Untargeted nuclear magnetic resonance (H NMR) metabolomics was applied in 84 umbilical cord blood and maternal blood samples obtained from 48 IUGR and 36 appropriate for gestational age (AGA) deliveries.

The Centers for Disease Control and Prevention's (CDC) Advisory Committee on Immunization Practices in association with ACOG state that the vaccine is safe to be given any trimester during pregnancy. However, due to a lack of communication, the public is unaware of the effects of influenza A vaccination in pregnancy. Read More

The CErebro Placental RAtio as indicator for delivery following perception of reduced fetal movements, protocol for an international cluster randomised clinical trial; the CEPRA study.

BMC Pregnancy Childbirth 2021 Apr 9;21(1):285. Epub 2021 Apr 9.

Department of Obstetrics and Gynaecology, University of Groningen, University Medical Center Groningen, Groningen, The Netherlands.

Background: Routine assessment in (near) term pregnancy is often inaccurate for the identification of fetuses who are mild to moderately compromised due to placental insufficiency and are at risk of adverse outcomes, especially when fetal size is seemingly within normal range for gestational age. Although biometric measurements and cardiotocography are frequently used, it is known that these techniques have low sensitivity and specificity. In clinical practice this diagnostic uncertainty results in considerable 'over treatment' of women with healthy fetuses whilst truly compromised fetuses remain unidentified. Read More

The safety of passive hypothermia during assessment for hypoxic ischaemic encephalopathy.

Early Hum Dev 2021 Mar 18;157:105351. Epub 2021 Mar 18.

Nottingham University Hospitals NHS Trust, Nottingham, UK.

Introduction: Hypoxic ischaemic encephalopathy (HIE) is poorly predicted by markers of hypoxic ischaemic (HI) delivery. Repeated examination of infants with HI markers facilitates diagnostic certainty of HIE severity. When infants with HIE are nursed at incubator ambient air-temperature set to achieve normothermia, there is sometimes associated hyperthermia, a predictor of poor outcome. Read More

Strategies to improve neurodevelopmental outcomes in babies at risk of neonatal hypoglycaemia.

Lancet Child Adolesc Health 2021 Apr 6. Epub 2021 Apr 6.

Liggins Institute, University of Auckland, Auckland, New Zealand.

Neonatal hypoglycaemia is associated with adverse development, particularly visual-motor and executive function impairment, in childhood. As neonatal hypoglycaemia is common and frequently asymptomatic in at-risk babies-ie, those born preterm, small or large for gestational age, or to mothers with diabetes, it is recommended that these babies are screened for hypoglycaemia in the first 1-2 days after birth with frequent blood glucose measurements. Neonatal hypoglycaemia can be prevented and treated with buccal dextrose gel, and it is also common to treat babies with hypoglycaemia with infant formula and intravenous dextrose. Read More

Association between Quantitative MR Markers of Cortical Evolving Organization and Gene Expression during Human Prenatal Brain Development.

Cereb Cortex 2021 Apr 9. Epub 2021 Apr 9.

The Fetal-Neonatal Neuroimaging and Developmental Science Center, Boston Children's Hospital, Boston, MA 02115, USA.

The relationship between structural changes of the cerebral cortex revealed by Magnetic Resonance Imaging (MRI) and gene expression in the human fetal brain has not been explored. In this study, we aimed to test the hypothesis that relative regional thickness (a measure of cortical evolving organization) of fetal cortical compartments (cortical plate [CP] and subplate [SP]) is associated with expression levels of genes with known cortical phenotype. Mean regional SP/CP thickness ratios across age measured on in utero MRI of 25 healthy fetuses (20-33 gestational weeks [GWs]) were correlated with publicly available regional gene expression levels (23-24 GW fetuses).

Ambient and household air pollution on early-life determinants of stunting-a systematic review and meta-analysis.

Environ Sci Pollut Res Int 2021 Apr 9. Epub 2021 Apr 9.

Environmental Health Division, Vital Strategies, New York office: 100 Broadway, 4th Floor, New York, NY, 10005, USA.

Stunting is an important risk factor for early growth and health implications throughout the life course, yet until recently, studies have rarely focused on populations exposed to high levels of particulate matter pollution or on developing countries most vulnerable to stunting and its associated health and developmental impacts. We systematically searched for epidemiologic studies published up to 15 August 2020 that examined the association between ambient and household particulate exposure and postnatal stunting (height-for-age z-score) and prenatal determinants (small for gestational age or SGA, or equivalent) of stunting. We conducted the literature search in PUBMED, MEDLINE, EMBASE, and Web of Science databases in August 2020, using keywords including, but not limited to, "particulate matter," "indoor/household air pollution," and "adverse birth outcomes," to identify relevant articles.

Front Pediatr 2021 23;9:597415. Epub 2021 Mar 23.

Dipartimento di Scienze della Vita e Sanità Pubblica, Unità Operativa Complessa di Neonatologia, Fondazione Policlinico Universitario A. Gemelli, Istituto di Ricovero e Cura a Carattere Scientifico, Rome, Italy.

The study investigates the role of the oxidative and proteolytic inactivation of alpha-1 antitrypsin (AAT) in the pathogenesis of bronchopulmonary dysplasia (BPD) in premature infants. Bronchoalveolar lavage fluid (BALF) samples were collected on the 3rd day of life from mechanically ventilated neonates with gestational age ≤ 30 weeks and analyzed without previous treatment (top-down proteomics) by reverse-phase high-performance liquid chromatography-electrospray ionization mass spectrometry. AAT fragments were identified by high-resolution LTQ Orbitrap XL experiments and the relative abundances determined by considering the extracted ion current (XIC) peak area. Read More
