Oxidative stress in preterm infants: Overview of current evidence and future prospects

2020

Preterm birth (PTB), defined as parturition prior to 37 weeks of gestation, is the leading cause of morbidity and mortality in the neonatal population. The incidence and severity of complications of prematurity increase with decreasing gestational age and birthweight. The aim of this review study is to select the most current evidence on the role of oxidative stress in the onset of preterm complication prevention strategies and treatment options with pre-clinical and clinical trials. We also provide a literature review of primary and secondary studies on the role of oxidative stress in preterm infants and its eventual treatment in prematurity diseases. We conducted a systematic literature s…

Ramadan During Pregnancy – Fasting, Nutrition, Sleep Patterns and Offspring Health at Birth: A Cross-Sectional Study

2020

Background: Intrauterine exposure to Ramadan is associated with adverse offspring health outcomes. Yet, the dynamics behind these associations remain largely unexplored. We investigate if maternal intermittent fasting or other lifestyle changes during Ramadan affect birth outcomes, and determine whether nutritional and sleep behavior during non-fasting hours influences the fasting-birth weight association. Methods: Linear regressions are estimated using OLS to identify the associations between fasting, sleep behavior, sweets consumption and birth weight, 5-minute APGAR score and gestational age. Interaction terms between fasting and other behaviors are included to explore the potential mode…

Olfaction in the fetal and premature infant: functional status and clinical implications.

2004

This article considers olfaction as a functioning source of information for the fetus and the neonate, born on term or prematurely. It aims to present how odors are involved in the sensory continuity between the prenatal and postnatal environments and how they influence the earliest adaptive responses of newborns in the realms of self-regulation, emotional balance, feeding, and social interactions.Finally, it evaluates odors as sensory means to ameliorate the physiologic and behavioral responses of preterm infants to the adverse impacts of separation from mother, nonoral feeding, or iatrogenic distress.

A Smartphone App to Promote Healthy Weight Gain, Diet, and Physical Activity During Pregnancy (HealthyMoms): Protocol for a Randomized Controlled Tri…

2019

Background: Excessive gestational weight gain is common and associated with adverse outcomes both in the short and long term. Although traditional lifestyle-based interventions have shown to mitigate excess gestational weight gain, little is known about whether mobile Health (mHealth) apps can promote healthy weight gain, diet, and physical activity during pregnancy. Objective: The primary aim of the HealthyMoms trial is to determine the effectiveness of a smartphone app (HealthyMoms) for mitigating excess gestational weight gain during pregnancy. Secondary aims are to determine the effectiveness of the app on dietary habits, physical activity, body fatness, and glycemia during pregnancy. M…

Maternal Metabolic Health Parameters During Pregnancy in Relation to Early Childhood BMI Trajectories

2018

Objective The objective of this study was to evaluate the associations between maternal metabolic parameters and early childhood BMI trajectories. Methods Two thousand two hundred fifty-one children born in Spain between 2004 and 2008 were analyzed. Five BMI z score trajectories from birth to age 4 years were identified by using latent class growth analysis. Multinomial regression assessed the associations between maternal metabolic parameters and offspring's BMI trajectories. Results Children in the reference BMI trajectory had average size at birth followed by a slower BMI gain. Maternal prepregnancy obesity was associated with trajectories of accelerated BMI gain departing from either hi…

Granulozytenfunktion bei Frühgeborenen ab der 34. Schwangerschaftswoche und bei reifen Neugeborenen

1999

BACKGROUND Preterm and term neonates have an increased risk to develop severe bacterial infections. Impairment of neutrophil function may be responsible for this increased risk. Other diseases related to prematurity like retinopathia of prematurity (ROP) or broncho-pulmonary dysplasia (BPD) on the other hand may be due to poorly controlled O2-radical production. PATIENTS AND METHODS Blood samples of 112 premature (34 weeks of gestation and older) and term neonates were analysed. Blood samples of 23 healthy adults (18 to 50 years old) served as controls. O2-radical production and phagocytosis of neutrophils were determined by flow cytometry, using a commercial test system. RESULTS Under the …

Objectively recorded physical activity and the association with gestational diabetes

2014

The aim of this population-based study was to assess the association between objectively recorded physical activity (PA) in early gestation and gestational diabetes mellitus (GDM) identified at 28 weeks of gestation in a multi-ethnic cohort of healthy pregnant women in Oslo, Norway. In total, 759 women were included. In early gestation (<20 weeks), light-, moderate-, and vigorous-intensity PA and number of steps were objectively recorded (SenseWear™ Armband Pro3), and self-reported PA, demographics, and anthropometrics were collected. The 75-g oral glucose tolerance test was performed at 28 weeks of gestation. Women with GDM had fewer objectively recorded steps (mean 7964 steps/day vs 8879 …

A randomized controlled trial of intervention in fear of childbirth*1

2001

Abstract OBJECTIVE: To compare intensive and conventional therapy for severe fear of childbirth. METHODS: In Finland, 176 women who had fear of childbirth were randomly assigned at the 26th gestational week to have either intensive therapy (mean 3.8 ± 1.0 sessions with obstetrician and one with midwife) or conventional therapy (mean 2.0 ± 0.6 sessions), with follow-up 3 months postpartum. Pregnancy-related anxiety and concerns, satisfaction with childbirth, and puerperal depression were assessed with specific questionnaires. Power analysis, based on previous studies, showed that 74 women per group were necessary to show a 50% reduction in cesarean rates. RESULTS: Birth-related concerns decr…

First-trimester reversed end-diastolic flow in the umbilical artery is not always an ominous sign

2003

We report five cases of first-trimester reversed end-diastolic flow in the umbilical artery. Diagnoses were performed between 8 and 12 gestational weeks. All but one case appeared as a transient early finding. Second-trimester fetal demise occurred in two cases. One case delivered at 32 weeks with severe growth restriction but recovered well. The other two cases had a good pregnancy outcome. Our experience suggests that this early Doppler finding is not always an ominous sign.
