BACKGROUND: Children with lower birth weight are at increased risk of asthma symptoms. We examined associations of fetal and infant growth with childhood lung function and asthma. METHODS: This study was embedded in a population-based prospective cohort study among 5,635children. Growth was estimated by repeated ultrasounds in 2nd and 3th trimester, and measured at birth and at 3, 6 and 12 months. At age 10 years, spirometry was performed and asthma was assessed by parental questionnaire...

AIM: We aimed to investigate maternal serum angiogenic marker profiles within 1 week prior to delivery in cases of gestational hypertension (GH), pre-eclampsia (PE), and/or fetal growth restriction (FGR) with different clinical conditions. METHODS: We enrolled 165 women with singleton pregnancy. The participants were classified based on three characteristics: (i) proteinuria (GH and PE); (ii) FGR (PE with FGR [PE + FGR], PE alone, and FGR alone); and (iii) onset (early onset PE [EO PE] and late-onset PE [LO PE])...

OBJECTIVE: We assessed whether umbilical cord blood placental growth factor (PlGF) levels at delivery are associated with fetal growth. METHODS: From a prospective population-based cohort study we included 3,461 live singleton births. Fetal growth was assessed by birth weight, fetal growth pattern, and fetal growth restriction (FGR; decrease in growth between the second trimester and birth of ≥40 percentiles). In all analyses the highest PlGF multiple of the median (MoM) quintile was used as the reference category...

In the immature lung, inflammation and injury disrupt epithelial-mesenchymal interactions required for normal development. Innate immune signaling and NF-κB activation disrupt the normal expression of multiple mesenchymal genes playing key roles in airway branching and alveolar formation. To test the role of the NF-κB pathway specifically in lung mesenchyme, we utilized the mesenchymal Twist2-Cre to drive expression of a constitutively active IKKβ mutant (IKKβca) in developing mice. Embryonic Twist2-IKKβca mice were generated in expected numbers and appeared grossly normal...

BACKGROUND: Hypoglycaemia accounts for approximately one tenth of term admissions to neonatal units, can cause long-term neurodevelopmental impairment and is associated with significant burden to the affected infants, families and the health system. OBJECTIVE: To define the prevalence, length and cost of admissions for hypoglycaemia in infants born at greater than 35 weeks gestation and to identify antenatal and perinatal predictors of those outcomes. MATERIAL AND METHODS: This was a retrospective audit of infants admitted for hypoglycaemia between 1/1/2012 and 31/12/2015, in a level three neonatal intensive care unit at King's College Hospital NHS Foundation Trust, London...

Undifferentiated connective tissue diseases (UCTDs) are a heterogeneous group of disorders characterized by symptoms and signs suggestive of systemic autoimmune rheumatic disease (ARD), but which do not fulfill all the established criteria for definite diagnosis of a condition. Although a third of UCTDs can progress to a definite ARD within months or years, most UCTDs can remain stable for years with minimal disease activity. The annual incidence of UCTD in the general population ranges from 14 to 140 per 100 000 people...

Although pre-eclampsia affects 5-10% of pregnancies globally and is responsible for substantial maternal and perinatal morbidity and mortality, currently there is no cure other than delivery of the baby. Predictive screening tests based on clinical risk factors, with or without the addition of biomarkers and imaging, have been developed, but adoption into clinical practice is limited by suboptimal test performance. Once established pre-eclampsia is diagnosed, a woman is usually managed expectantly prior to 37weeks' gestation to reduce perinatal morbidity and mortality associated with iatrogenic prematurity until maternal or fetal triggers for delivery mean that risks of pregnancy prolongation outweigh the benefits...

AIM: Preterm birth is the world's leading cause of neonatal death. Unfortunately, the pathophysiology of preterm birth remains poorly understood. Sjögren-Larsson syndrome is a rare, neurometabolic disorder caused by a fatty aldehyde dehydrogenase deficiency. A majority of patients with Sjögren-Larsson syndrome is born preterm. METHODS: Data of all known Dutch patients with Sjögren-Larsson syndrome and all cases reported in literature were analyzed to learn from preterm birth in context of this rare disease...

Restricted intrauterine fetal growth is an indicator of poor infant health outcomes. Classifying abnormal fetal growth, however, is challenging because there is no accepted definition of "normal" and "abnormal." Many standardized fetal growth curves have been created from populations of healthy pregnancies, excluding congenital abnormalities and, historically, have also excluded "non-white" women (Lubochenco, 1963, Pediatrics, 32: 793-800). More recently, assuming that ethnicity is a reliable, valid, and unchanging variable, customized growth charts have adjusted for ethnicity, in addition to maternal height, weight, and parity...

The amino acid arginine is a physiological precursor to nitric oxide, which is a key mediator of embryonic survival, fetal growth, and pregnancy maintenance. We evaluated the association between consumption of the amino acid arginine and the rate of adverse birth outcomes using data from a double-blind, randomized, placebo-controlled micronutrient supplementation trial among pregnant women in Dar es Salaam, Tanzania (2001-2004). Dietary intakes of arginine were assessed using repeated 24-hour recalls that were administered throughout pregnancy...

BACKGROUND: Magnesium (Mg) is an essential mineral required to regulate body temperature, nucleic acid, and protein synthesis with an important role in maintaining nerve and muscle cell electrical potentials. It may reduce fetal growth restriction and preeclampsia as well as increase birth weight. This study aimed to assess the effects of consuming Mg supplementation during pregnancy on pregnancy outcomes. MATERIALS AND METHODS: This is a randomized controlled trial with three sixty populated groups of pregnant women...

Pregnancy poses a challenge for the immune systems of placental mammals. As fetal tissues are semi-allogeneic and alloantibodies that commonly develop in the mother, the fetus and the placenta might be subject to complement-mediated immune attack with the potential risk of adverse pregnancy outcomes. Here, I describe how the use of animal models was pivotal in demonstrating that complement inhibition at the fetomaternal interface is essential for a successful pregnancy. Studies in animals also helped the identification of uncontrolled complement activation as a crucial effector in the pathogenesis of recurrent miscarriages, intrauterine growth restriction, preeclampsia, and preterm birth...

The introduction of continuous electronic fetal heart rate monitoring (EFM) in labour has coincided with a steady and remarkable fall in perinatal mortality. Whether this is cause or coincidence remains unclear because randomised trials have been underpowered. Attempts to improve the sensitivity and specificity of fetal compromise detection using fetal blood sampling and pH measurement, pulse oximetry, and fetal electrocardiogram analysis have failed to provide evidence of additional value in randomised trials...

Sildenafil is a new approach to treat fetal growth restriction (FGR) and preeclampsia. We performed a systematic meta-analysis to evaluate effects of sildenafil. Our search identified 22 animal studies (mouse, rat, rabbit, sheep, and guinea pigs) and 2 human randomized controlled trials. Data were pooled using ratio of means and mean differences with 95% confidence intervals for fetal growth and maternal blood pressure, respectively. Meta-regression analyses were performed for study-related factors that might affect efficacy of sildenafil, including the model used (healthy pregnancy versus FGR/preeclampsia) and route of administration...

Pregnancy-associated malaria (PAM) poses a threat to both the mother and fetus, increasing the risk of severe maternal anemia, fetal growth restriction and low birth weight infants. Two vaccines are currently in development to protect women from Plasmodium falciparum in pregnancy. Both vaccine constructs target the ID1-DBL2Xb domain of VAR2CSA, a protein expressed on the surface of infected erythrocytes (IEs) that mediates parasite sequestration in the placenta. Although development of an effective vaccine may be hampered by ID1-DBL2Xb polymorphisms expressed by field isolates, a recent study showed that genetic variation of this domain in South American parasite populations is much lower than in other geographical locations...

INTRODUCTION: Increase in Nitric Oxide (NO) may be important in vascular adaptation needed to accommodate increased uteroplacental blood flow as pregnancy advances. Hence, in certain conditions like Pregnancy Induced Hypertension (PIH) and Fetal Growth Restriction (FGR), NO donors may play an effective role in increasing uteroplacental perfusion. Transdermal route appears to be a safe and effective route. AIM: To evaluate the effect of nitroglycerine patch on Doppler velocity waveforms of the uterine, umbilical and fetal middle cerebral arteries in patients with chronic placental insufficiency...
