BACKGROUND: Most evidence on the association between malaria in pregnancy and adverse pregnancy outcomes focuses on falciparum malaria detected at birth. We assessed the association between the number and timing of falciparum and vivax malaria episodes during pregnancy on small-for-gestational-age (SGA) and preterm birth. METHODS: We analysed observational data collected from antenatal clinics on the Thailand-Myanmar border (1986-2015). We assessed the effects of the total number of malaria episodes in pregnancy on SGA and the effects of malaria in pregnancy on SGA, very preterm birth, and late preterm birth, by the gestational age at malaria detection and treatment using logistic regression models with time-dependent malaria variables (monthly intervals)...

Preterm birth is the leading cause of neonatal and infant mortality and a substantial portion of neonatal morbidities. The perinatal mortality and morbidity statistics in developing countries are inadequate. In this study, we assessed prevalence and health outcomes of preterm deliveries in tertiary care university hospitals. A retrospective study of hospital records of premature babies born in all the five governmental tertiary care settings during the time interval of 2013-2015 in Shiraz was conducted. Result of this study showed that there was an overall 127...

BACKGROUND: Breast milk is a God-given gift that conveys a mother's love and compassion and that is made according to the needs and age of the child. Mothers who are interested in the welfare of their newborns tend to breastfeed their children. Training programs have been shown to improve breastfeeding self-efficacy in terms of both duration and amount. PURPOSE: The aim of this study was to evaluate the effect of using the progressive muscle relaxation (PMR) technique on the self-efficacy of breastfeeding in mothers with preterm infants...

The placenta is important in providing a healthy environment for the fetus and plays a central role in the pathophysiology of preeclampsia (PE). Fetal and placental developments are influenced by epigenetic programming. There is some evidence that PE is controlled to an altered circadian homeostasis. In a nested case-control study embedded in the Rotterdam Periconceptional Cohort, we obtained placental tissue, umbilical cord leukocytes (UCL), and human umbilical venous endothelial cells of 13 early-onset PE, 16 late-onset PE and 83 controls comprising 36 uncomplicated and 47 complicated pregnancies, i...

PURPOSE: Preterm birth (PTB) is a complex trait with strong genetic background, whose etiology is not fully understood. It was recently suggested that pregnancy duration is affected by fetal genetic variation even more than by the maternal genome. Vitamin D receptor (VDR) is involved in embryonic implantation and fertility. We studied the association between both maternal and neonatal vitamin D receptor (VDR) genetic variation and PTB. METHODS: Maternal and fetal (umbilical cord) DNA was isolated from Jewish Israeli idiopathic preterm newborns (24-36 weeks, n = 146) and control term newborns (>37 weeks, n = 229)...

OBJECTIVE: Vitamin D has many important functions in our body. Especially in intrauterine and early infancy periods, Vitamin D plays a major role in bone development, growth, and the maturation of tissues such as lung and brain. Fetus is dependent on the mother in terms of Vitamin D and maternal Vitamin D deficiency results in a Vitamin D deficient newborn. The purpose of this study was to determine the levels of Vitamin D in newborns and to investigate the association between Vitamin D status of the baby and neonatal hypocalcemia...

Preterm infants frequently develop atypical sensory profiles, the tactile modality being particularly affected. However, there is a lack of recent investigation of neonatal tactile perception in a passive context, especially in preterms who are particularly exposed to this tactile stimuli. Our aims were to provide evidence of orienting responses (behavioral modifications directing subject's attention towards stimuli) and habituation to passive tactile stimuli in preterm neonates, to explore their ability to perceive spatial and temporal aspects of the stimulus, and to evaluate the effect of clinical factors on these abilities...

INTRODUCTION: Concerns with prescription antidepressant use in pregnant women have instigated the examination of potential associations between fetal exposure to antidepressant medication and outcomes including preterm delivery, congenital malformations, perinatal and post-natal adverse events, persistent pulmonary hypertension, and mortality. The retrospective cohort model is an often utilized study design. The objective of this review is to evaluate the literature on antidepressant use in pregnancy conducted as retrospective cohorts in national/regional medical, or claims databases that assess neonatal and infant outcomes for agreement between studies, ultimately providing a methodological and outcomes summary for future scientific endeavors...

OBJECTIVE: Neonatal resuscitation guidelines recommend that newborn infants are stimulated to assist with the establishment of regular respirations. The mode, site of application and frequency of stimulations are not stipulated in these guidelines. The effectiveness of stimulation in improving neonatal transition outcomes is poorly described. METHODS: We conducted a retrospective review of video recordings of neonatal resuscitation at a tertiary perinatal centre...

Intracerebral hemorrhage is a rare event during pregnancy that can result in serious morbidity and mortality for the mother and infant. In this article, we describe a case involving a multiparous woman at 34 weeks gestation who presented with a 5-cm intracerebral bleed. Within 2 hours of presenting, she underwent an emergency cesarean and craniotomy to remove the hematoma. The woman's altered mental status fully abated, and she was discharged with minimal neurologic deficits. The newborn was born healthy.

Piglets are often used as experimental models for studying cerebrovascular responses in newborn infants. However, the mechanical characteristics of piglets' middle cerebral arteries (MCA) are not well characterized. Additionally, the vessels' response to dopamine, the most commonly used vasopressor in newborns, is not characterized in piglets' MCA. Finally, the influence of preterm birth on the dopamine response is not known. The aim of this current was to compare by wire myography the active and passive mechanical characteristics and dopamine concentration-response relations of MCAs isolated from preterm and term newborn piglets...

Placental abruption, early separation of the placenta, is associated with preterm birth and perinatal mortality, but associations with other neonatal morbidities remains under-studied. We examined the association between abruption and newborn outcomes. We analyzed n = 223,341 singleton deliveries from the Consortium on Safe Labor Study, a retrospective, multi-site, observational study (2002-2008) of electronic medical records in the U.S. Adjusted relative risks (RR), incident ratio ratios and 99% confidence intervals (CI) were estimated...

A novel endogenous peptide cleaved from 197-213 AA of β-casein, named β-casein 197, was identified by tandem mass spectrometry. β-casein 197 constituted a significant proportion of the peptide content in preterm milk. This study investigated the antibacterial effects and mechanisms against common pathogenic bacteria. Six bacterial strains were selected for this study: Escherichia coli, Staphylococcus aureus, Yersinia enterocolitica, Listeria monocytogenes, Klebsiella pneumonia and Bacillus subtilis. After synthesis, serial twofold dilutions of β-casein 197 were added to select for sensitive bacteria...

A latent measure of white matter microstructure (g WM) provides a neural basis for information processing speed and intelligence in adults, but the temporal emergence of g WM during human development is unknown. We provide evidence that substantial variance in white matter microstructure is shared across a range of major tracts in the newborn brain. Based on diffusion MRI scans from 145 neonates [gestational age (GA) at birth range 23(+2)-41(+5) weeks], the microstructural properties of eight major white matter tracts were calculated using probabilistic neighborhood tractography...

INTRODUCTION: In high-income countries, a reduced clinical threshold for obstetric interventions such as labour induction (LI) and prelabour caesarean delivery (PLCD) has played a substantial role in increasing rates of late preterm births. However, the association between provider-initiated delivery and perinatal outcomes have not been studied in a multicountry setting including low-income and middle-income countries. METHODS: 286 hospitals in 29 countries participated in the WHO Multi-Country Survey on Maternal and Newborn Health and yielded 2 52 198 singleton births of at least 34 weeks in 2010-2011...

BACKGROUND: When feeding preterm infants, donor milk is preferred if the mother's own milk is unavailable. Pasteurization may have detrimental effects on bioactivity, but more information is needed about its effects on the immunological compounds. Research aim: This work has two main aims: evaluate the antibody profile of colostrum and study the quantitative variations in the antibodies' level and specific reactivity after undergoing Holder pasteurization. The authors focused on immunoregulatory components of colostrum (antidietary antibodies and TGF-β2) in the neonatal gut...

AIM: There are two classical managements in gastroschisis: primary or delayed closure. From 2007 on, a multidisciplinary approach protocol based in preterm caesarean delivery at 34-35th gestational age (in order to minimize peel injury) plus primary closure is followed in our institution. Prior to this, term delivery, either by caesarean section or not, was the rule. METHODS: Retrospective study of gastroschisis's patients before (1978-2006) and after (2007-2016) protocol approval...

Although the effects of antenatal corticosteroid therapy in clinical improvement and pulmonary maturation in preterm have been described, little is known on premature newborn puppies. This study aimed to evaluate the effect of maternal administration of a single dose of prenatal betamethasone on lung function of preterm newborn puppies in the first hours of life, especially from the clinical point of view and acid-base balance. A prospective study was conducted involving 21 puppies allocated into three experimental groups: Term Group (63 days post-ovulation), Preterm-Treated Group (57 days post-ovulation and maternal administration of a single dose of 0...
