Ayten Bilgin, Dieter Wolke
BACKGROUND: Regulatory problems (excessive crying, feeding, and sleeping difficulties), specifically their comorbidity, are early warning signs of future problems. Insensitive parenting and neurodevelopmental vulnerabilities have been suggested as factors explaining development or maintenance of regulatory problems. Nevertheless, none of the previous studies investigated these factors within the same sample across infancy, taking into account the reciprocal influences between maternal sensitivity and regulatory problems...

OBJECTIVE: Pre-eclampsia, growth retardation and preterm delivery are the most common reasons leading to increased maternal and perinatal mortality. The increased expression of hypoxia induced factors, such as HIF-1, triggers the overexpression of anti-angiogenic genes. The aim of this study was to determine the transcriptional activity of individual pro- and anti-angiogenic markers (VEGF, HIF-1, sEng, Flt-1, PlGF-1) in maternal blood samples from patients with spontaneous preterm labor, preterm labor in combination with pre-eclampsia and fetal growth restriction in comparison with physiologically terminated pregnancies...

In the Netherlands, the recommended priming immunization schedule for diphtheria, tetanus, pertussis and polio (DTaP-IPV) is at 2, 3 and 4 months of age. We evaluated the compliance with the recommended schedule, as well as its characteristics. We included all infants born between 2007 and 2012 who received minimally one DTaP-IPV vaccination (n = 1,061,578). Infants complied with the schedule if they received the first vaccination between 6 and 9 weeks of age, and the second and third vaccination 2-6 weeks after the first and second vaccination...

BACKGROUND: Premature infants are highly vulnerable to infection. This is partly attributable to the preterm immune system, which differs from that of the term neonate in cell composition and function. Multiple studies have found differential DNA methylation (DNAm) between preterm and term infants' cord blood; however, interpretation of these studies is limited by the confounding factor of blood cell composition. This study evaluates the epigenetic impact of preterm birth in isolated hematopoietic cell populations, reducing the concern of cell composition differences...

BACKGROUND: Measurement of mean arterial blood pressure (MABP) is feasible during neonatal transition. OBJECTIVE: The objective of this study was to investigate a potential influence of MABP on the cerebral regional oxygen saturation (crSO2) in preterm and term infants during the immediate neonatal transition. MATERIALS AND METHODS: Preterm and term infants were included in this observational study. The crSO2 was measured by near-infrared spectroscopy with the INVOS 5100C (Somanetics Corp...

Importance: Actinomyces is commonly found in many areas of the body where it derives a benefit without harming the host. When it does infect the host during pregnancy, is that infection a threat to the obstetric patient and does that infection cause adverse pregnancy outcomes? Objective: The aim of this study was to review what is known about Actinomyces infections and the impact of an Actinomyces infection on pregnancy outcomes. Evidence Acquisition: A PubMed search was undertaken with the search years unlimited to April 1, 2016, and restricted to articles in English...

Background: Peptidomics research has demonstrated that protease activity is higher in breast milk from preterm-delivering mothers than from term-delivering mothers. However, to our knowledge, the effect of the degree of prematurity and postnatal age on proteases and protease inhibitors in human milk remains unknown.Objective: We aimed to determine the change of proteases and protease inhibitors in milk from mothers who delivered prematurely across gestational age (GA) and postnatal age.Methods: Milk samples were collected from 18 mothers aged 26-40 y who delivered preterm infants and who lacked mastitis...

While the trajectory of self-esteem from adolescence to adulthood varies from person to person, little research has examined how differences in early developmental processes might affect these pathways. This study examined how early motor skill development interacted with preterm birth status to predict self-esteem from adolescence through the early 30s. We addressed this using the oldest known, prospectively followed cohort of extremely low birth weight (<1000 g) survivors (N = 179) and normal birth weight controls (N = 145) in the world, born between 1977 and 1982...

BACKGROUND: Intrauterine infection is a significant cause of early preterm birth. We have developed a fetal-neonatal model in the rhesus macaque to determine the impact of chronic intrauterine infection with Ureaplasma parvum on early neonatal reflexes and brain development. METHODS: Time-mated, pregnant rhesus macaques were randomized to be inoculated with U. parvum (serovar 1; 10(5)cfu) or control media at ~120 dGA. Neonates were delivered by elective hysterotomy at 135-147 dGA (term=167d) stabilized and cared for in our nonhuman primate neonatal intensive care unit...

BACKGROUND: Maternal breast milk (MBM) is enriched in microRNAs, factors that regulate protein translation throughout the human body. MBM from mothers of term and preterm infants differ in nutrient, hormone, and bioactive-factor composition, but the microRNA differences between these groups have not been compared. We hypothesized that gestational age at delivery influences microRNA in MBM, particularly microRNAs involved in immunologic and metabolic regulation. METHODS: MBM from mothers of premature infants (pMBM) obtained 3-4 weeks post-delivery was compared with MBM from mothers of term infants obtained at birth (tColostrum) and 3-4 weeks post-delivery (tMBM)...

AIM: The issue of preterm birth due to exposure to magnetic fields from power lines is unclear. Exposure to electromagnetic field in uterus has been hypothesized as possible preterm birth. The aim of the present study was to determine whether living closer to high voltage power lines increased the risk of preterm labor. METHODS: In a nested case-control study, 135 cases of singleton live spontaneous preterm birth in Rohani hospital, Babol, Iran, during the period between 2013 and 2014 were studied...

Preterm birth (PTB) is one of the major health-care challenges of our time. Being born too early is associated with major risks to the child with potential for serious consequences in terms of life-long disability and health-care costs. Discovering how to prevent PTB needs to be one of our greatest priorities. Recent advances have provided hope that a percentage of cases known to be related to risk factors may be amenable to prevention; but the majority of cases remain of unknown cause, and there is little chance of prevention...

In this review of 126 publications, we report that an overwhelming majority of adults born at preterm gestations remain healthy and well. However, a small, but a significant fraction of them remain at higher risk for neurological, personality and behavioral abnormalities, cardio-pulmonary functional limitations, systemic hypertension, and metabolic syndrome compared to their term-born counterparts. The magnitude of increased risk differed across organ systems, and varied across reports. The risks were proportional to the degree of prematurity at birth and seemed to occur more frequently among preterm infants born in the final two decades of the 20(th) century and later...

BACKGROUND: Oro/nasopharyngeal suction is a method used to clear secretions from the oropharynx and nasopharynx through the application of negative pressure via a suction catheter or bulb syringe. Traditionally, airway oro/nasopharyngeal suction at birth has been used routinely to remove fluid rapidly from the oropharynx and nasopharynx in vigorous and non-vigorous infants at birth. Concerns relating to the reported adverse effects of oro/nasopharyngeal suctioning led to a practice review and routine oro/nasopharyngeal suctioning is no longer recommended for vigorous infants...

Study Objectives: Preterm birth and fetal growth restriction (FGR) are both associated with risk of hypertension in adulthood. Mechanisms leading to this pathology are unclear. In children aged 5-12 years, who were born preterm and FGR, we used sleep as a tool to assess autonomic control with assessment of cardiovascular structure and function. Methods: 18 children born preterm and FGR, 15 born preterm with appropriate birth weights (AGA) and 20 AGA term-born children were studied...

The cervix is a unique organ able to dramatically change its shape and function by serving as a physical barrier for the growing fetus and then undergoing dramatic dilation allowing for delivery of a term infant. As a result, the cervix endures changing mechanical forces from the growing fetus. There is an emerging concept that the cervix may change or remodel "early" in many cases of spontaneous preterm birth. However, the mechanical role of the cervix in both normal and preterm birth remains unclear. Therefore, the primary objective of this study was to determine the mechanical and structural response of murine cervical tissue throughout a normal gestational time course...

Concerns have been raised about the health and development of children conceived by assisted reproductive technologies (ART) since 1978. Controversially, ART has been linked with adverse obstetric and perinatal outcomes, an increased risk of birth defects, cancers, and growth and development disorders. Emerging evidence suggests that ART treatment may also predispose individuals to an increased risk of chronic ageing related diseases such as obesity, type 2 diabetes and cardiovascular disease. This review will summarize the available evidence on the short-term and long-term health outcomes of ART singletons, as multiple pregnancies after multiple embryos transfer, are associated with low birth weight and preterm delivery, which can separately increase risk of adverse postnatal outcomes, and impact long-term health...

While evidence suggests that beginning an external cephalic version (ECV) before term (34(0/7) to 36(6/7) ) compared to after term may be associated with an increase in late preterm birth (34(0/7) to 36(6/7) weeks), it remains unknown what might account for this risk. The objective of the present study is to further investigate the association between ECV before term and late preterm birth MATERIAL AND METHODS: Secondary analysis of data collected from the international, multicenter Early ECV trials. We evaluated the relation between ECV exposure and late preterm birth (34(0/7) to 36(6/7) weeks), as well as if additional risk factors for preterm birth (e...
