Objective: To determine the frequency and risk factors of small-for-gestational-age newborns in a high-risk maternity. Methods: This is an observational, cross-sectional, and case-control study, conducted in a public tertiary care maternity hospital. Data from 998 newborns and their mothers were collected through interviews and review of medical records and prenatal care cards. Some placentas underwent histopathological analysis. The variables of small-for-gestational-age and non-small-for-gestational-age newborns and of their mothers were statistically compared by means of Student's t test, Fisher's exact test, and odds ratio...

High incidence of missed abortion induces to search for its causes. Apart from genetic and anatomic uterine factors, the state of the decidual endometrium and implantation zone of chorionic structures of the gestational sac are of particular interest. Direct visualization of the intact decidual endometrium is possible with embryoscopy, however, there is lack of presented data of normal and pathological signs of the endometrium during pregnancy. This paper describes the changes of the endometrium in missed abortion obtained by hysteroscopy in 160 women with nonprogressive pregnancy after ART protocols...

About 1-3% of women experience early recurrent miscarriages, defined by ≥3 fetal loss before 14 weeks of gestation. About half of these recurrent early miscarriages could be related to a genetic cause. Pre-implantation genetic diagnosis is used in several European countries, but it is still prohibited in France except for couples at risk for transmission of severe genetic diseases. The immune dysregulation, and in particular allo-immune excessive response, could be responsible for fetal loss in remaining cases, although currently we lack biomarker to confirm the immune-mediated fetal loss...

BACKGROUND: Growth and nutrition are critical in neonatal care. Whether feeding guidelines improve growth and nutrition and reduce morbidity is unknown. PURPOSE: Feeding guidelines for very low birth-weight (VLBW) infants were implemented in our neonatal intensive care unit (NICU) to start and achieve full enteral feeds sooner, and increase weight gain over the first month. METHODS: Feeding guidelines for VLBW infants were implemented in January 2014, stratified by birth weight (<750, 750-1000, and 1000-1500 g)...

BACKGROUND: Results from uterine artery Doppler investigations suggest that the aetiology of late preeclampsia with fetal growth restriction may be more similar to the aetiology of early preeclampsia than with late preeclampsia without fetal growth restriction. We hypothesised that a small-for-gestational-age (SGA) birth in a late preeclamptic pregnancy may be associated with increased subsequent risk of early preeclampsia. We also studied effects of maternal factors on risks of preeclampsia recurrence...

The general assumption that brain size differences are an adequate proxy for subtler differences in brain organization turned neurobiologists toward the question why some groups of mammals such as primates, elephants, and whales have such remarkably large brains. In this meta-analysis, an extensive sample of eutherian mammals (115 species distributed in 14 orders) provided data about several different biological traits and measures of brain size such as absolute brain mass (AB), relative brain mass (RB; quotient from AB and body mass), and encephalization quotient (EQ)...

BACKGROUND: Prematurity and low birth weight are known risk factors for cognitive and developmental impairments, and school failure. Visual perceptual and visual motor skills seem to be among the most affected cognitive domains in these children. AIMS: To assess the influence of prematurity and low birth weight in visual cognitive skills and school performance. METHODS: We performed a prospective cohort study, which included 80 boys and girls in an age range from 5 to 13...

BACKGROUND: The amount of greenness around mothers' residences has been associated with positive birth outcomes; however, findings are inconclusive. Here we examine residential greenness and birth outcomes in a population-based birth cohort in Texas, a state with large regional variation in greenness levels, several distinct cities, and a diverse population. METHODS: We used Vital Statistics data to create a birth cohort (n=3,026,603) in Texas from 2000 to 2009...

Vital parameter monitoring of term and preterm infants during incubator care with self-adhesive electrodes or sensors directly positioned on the skin [e.g. photoplethysmography (PPG) for oxygen saturation or electrocardiography (ECG)] is an essential part of daily routine care in neonatal intensive care units. For various reasons, this kind of monitoring contains a lot of stress for the infants. Therefore, there is a need to measure vital parameters (for instance respiration, temperature, pulse, oxygen saturation) without mechanical or conductive contact...

INTRODUCTION: An increased risk of preterm birth in women with Joint Hypermobility Syndrome (JHS) or Ehlers-Danlos Syndrome (EDS) is suspected. MATERIAL AND METHODS: In this nationwide cohort study from 1997 through 2011, women with either JHS or EDS or both disorders were identified through the Swedish Patient Register, and linked to the Medical Birth Register. Thereby 314 singleton births to women with JHS/EDS before delivery were identified. These births were compared with 1,247,864 singleton births to women without a diagnosis of JHS/EDS...

BACKGROUND: Optimal gestational weight gain has not yet been clearly defined and remains one of the most controversial issues in modern perinatology. The role of optimal weight gain during pregnancy is critical, as it has a strong effect on perinatal outcomes. PURPOSE: In this study, gestational body mass index (BMI) change, accounting for maternal height, was investigated as a new criterion for gestational weight gain determination, in the context of fetal growth assessment...

While the problem of Pressure Ulcers (PU) in adults has received a great deal of attention, far less is known about PUs in neonates and children. The overall health status of children is generally better and multi-morbidity is limited to a small percentage of patients, like very low term neonates (born before 32 weeks of gestation age), newborns with congenital abnormalities, genetic disorders, perinatal distress syndrome or children with a limited immunity. Survival rates of both critically and chronically ill neonates, infants and children have improved dramatically in recent years, introducing new challenges for medical and nursing care...
