Symptom Burden and Factors Associated with Acute Respiratory Infections in the First Two Years of Life-Results from the LoewenKIDS Cohort.

Acute respiratory infections (ARIs) are the most common childhood illnesses worldwide whereby the reported frequency varies widely, often depending on type of assessment. Symptom diaries are a powerful tool to counteract possible under-reporting, particularly of milder infections, and thus offer the possibility to assess the full burden of ARIs. The following analyses are based on symptom diaries from participants of the German birth cohort study LoewenKIDS.

Anatomic accuracy, physiologic characteristics, and fidelity of very low birth weight infant airway simulators.

Background: Medical simulation training requires realistic simulators with high fidelity. This prospective multi-center study investigated anatomic precision, physiologic characteristics, and fidelity of four commercially available very low birth weight infant simulators.

Methods: We measured airway angles and distances in the simulators Premature AirwayPaul (SIMCharacters), Premature Anne (Laerdal Medical), Premie HAL S2209 (Gaumard), and Preterm Baby (Lifecast Body Simulation) using computer tomography and compared these to human cadavers of premature stillbirths.

Short courses of dual-strain probiotics appear to be effective in reducing necrotising enterocolitis.

Aim: Prophylactic probiotics to reduce necrotising enterocolitis (NEC) are mostly given for at least 28 days or until discharge. We describe the effects of a shorter duration dosing strategy.

Methods: Retrospective cohort study of neonates (birthweight 400-1500 g) in three neonatal intensive care units in Switzerland and Germany that embarked on probiotic prophylaxis given for 10 or 14 days, employing a fixed combination (Lactobacillus acidophilus plus Bifidobacterium infantis, each 10(9) CFU/day) licensed as a drug in Switzerland.

[Interdisciplinary care of newborns with epidermolysis bullosa and severe congenital ichthyoses].

Severe genodermatoses such as hereditary blistering diseases or Mendelian disorders of cornification may present as neonatal emergencies requiring interdisciplinary care. In particular, epidermolysis bullosa hereditaria, the collodion baby phenotype and harlequin ichthyosis represent serious clinical challenges with neonatal onset. This review summarizes dermatologically relevant aspects regarding pathogenesis, clinical presentation, diagnosis and therapy of these illnesses.

Prophylactic use of Lactobacillus acidophilus/Bifidobacterium infantis probiotics and outcome in very low birth weight infants.

Objective: To evaluate outcome data in an observational cohort of very low birth weight infants of the German Neonatal Network stratified to prophylactic use of Lactobacillus acidophilus/Bifidobacterium infantis probiotics.

Study Design: Within the observational period (September 1, 2010, until December 31, 2012, n=5351 infants) study centers were categorized into 3 groups based on their choice of Lactobacillus acidophilus/Bifidobacterium infantis use: (1) no prophylactic use (12 centers); (2 a/b) change of strategy nonuser to user during observational period (13 centers); and (3) use before start of observation (21 centers). Primary outcome data of all eligible infants were determined according to center-specific strategy.

[Birth weight percentile values for girls and boys under consideration of maternal height].

There is a linear relationship between maternal height and birth weight. For each 1 cm increase in maternal height, birth weight increases by 16.7 g.

Developmental delay in hypoxia-induced HO-1 expression predisposes to gut injury.

Aims: Necrotizing enterocolitis (NEC) is an often fatal disease that affects 5-8% of preterm newborn infants but does not occur in older infants and children. As carbon monoxide (CO) may exert protective effects against NEC, we assessed patterns of intestinal injury and investigated the expression of the CO-producing enzyme heme oxygenase-1 (HO-1) in mature and immature rat guts in response to hypercapnia and reoxygenation (H/R).

Methods: Gut barrier failure (increased permeability for dextran) was assessed in immature (newborn rats) and mature rats (weanling rats) subjected to H/R.

On weight gain during pregnancy: relationships between weight gain during pregnancy, duration of pregnancy and the somatic classification of neonates.

Background: Weight gain during pregnancy is an important parameter that is related to a number of perinatal outcomes. We aimed to analyse the relationships between weight gain during pregnancy, duration of pregnancy, and the somatic classification of the neonates as small, appropriate, or large for gestational age (SGA, AGA, LGA).

Material And Methods: Data were from the German perinatal survey of 1995-2000 (more than 2.

On the variability in preterm birth rate, birth weight, and somatic classification among neonates of mothers with the same body mass index.

Background: Maternal height and weight are important determinants of perinatal outcomes.Height and weight can be combined in the measure of body mass index (BMI). We aimed to investigate the utility of maternal BMI as a predictor of perinatal outcomes.

Somatic classification of neonates based on birth weight, length, and head circumference: quantification of the effects of maternal BMI and smoking.

We defined neonates as small, appropriate, or large for gestational age (SGA, AGA, LGA) based on birth weight, length, and head circumference. We analyzed the effects on the somatic classification of maternal body mass index (BMI) (<18.5, 18.

Offspring sex determines the impact of the maternal ACE I/D polymorphism on maternal glycaemic control during the last weeks of pregnancy.

Unlabelled: HYPOTHESIS/ INTRODUCTION: : We recently demonstrated that fetal sex may affect maternal glycaemic control in genetically prone mothers. We tested the hypothesis that fetal sex/fetal Y/X chromosomes might affect maternal glycaemic control during pregnancy depending on the maternal angiotensin converting enzyme (ACE) I/D polymorphism.

Material And Methods: : One thousand, three hundred and thirty-two Caucasian women without pre-existing diabetes and pre-existing hypertension with singleton pregnancies delivering consecutively at the Charité obstetrics department were genotyped.

Maternal and fetal PROGINS progesterone receptor polymorphism reduces the risk for transient tachypnea of the newborn.

Background: Transient tachypnea of the newborn (TTN) is the most common perinatal respiratory disorder. It was suggested that the pathogenesis of TTN might involve altered activity of female sex hormones. This study analyzed whether the PROGINS progesterone receptor polymorphism, which is less responsive to progesterone, is associated with TTN.

Probiotics for prevention of necrotising enterocolitis: an updated meta-analysis.

Several randomized controlled trials (RCTs) have investigated the prophylactic use of probiotics in preterm infants aimed at reducing the rate of necrotising enterocolitis (NEC). There are 4 meta-analyses on this subject. 2 more RCTs have been published since these meta-analyses were completed.

New evidence for the fetal insulin hypothesis: fetal angiotensinogen M235T polymorphism is associated with birth weight and elevated fetal total glycated hemoglobin at birth.

Background: Low birth weight is associated with an increased risk of cardiovascular events in later life. Insulin resistance is a key finding in adult patients with cardiovascular diseases. The neonatal phenotype of an individual with insulin resistance might be low birth weight, as insulin influences fetal growth.

Interaction of maternal peroxisome proliferator-activated receptor gamma2 Pro12Ala polymorphism with fetal sex affects maternal glycemic control during pregnancy.

It was suggested that fetal sex may substantially affect maternal glycemic control during pregnancy in genetically susceptible mothers. The peroxisome proliferator-activated receptor gamma2 (PPARgamma2) Pro12Ala polymorphism is known to affect glycemic control and may act in a sex-specific manner. This polymorphism is thus an attractive candidate to test this hypothesis using a second independent functionally relevant polymorphism.

Early subcutaneous administration of etanercept (Enbrel) prevents from hyperoxia-induced lung injury.

Both hyperoxia-induced proapoptotic sensitization of alveolar type II cells (TII cells) and high-stretch mechanical ventilation induced pulmonary inflammation are tumor necrosis factor alpha (TNFalpha) mediated. Therefore, binding of free TNFalpha should protect from TNFalpha-mediated acute lung injury and ameliorate the subsequently developing chronic lung disease. Here, the authors show that a single subcutaneous pretreatment of rat with etanercept, a recombinant p75 TNF receptor 2 human immunoglobulin G1 (IgG1) construct, inhibits the hyperoxia-induced and TNFalpha-mediated increase in the expression of TNFalpha receptor, the activation of caspase 3 in TII cells, and, as an early indicator of lung injury, the capillary-alveolar leakage and granulocyte number in lung lavage.

Impact of maternal body mass index on neonatal outcome.

Introduction: Maternal body mass index has an impact on maternal and fetal pregnancy outcome. An increased maternal BMI is known to be associated with admission of the newborn to a neonatal care unit. The reasons and impact of this admission on fetal outcome, however, are unknown so far.

Vascular endothelial growth factor as marker for tissue hypoxia and transfusion need in anemic infants: a prospective clinical study.

Objective: Oxygen-carrying capacity of blood is reduced in anemic infants because of low hemoglobin levels. Red blood cell transfusions become necessary if low hematocrit causes tissue hypoxia. No reliable parameters exist for detecting chronic tissue hypoxia.

Trefoil factors in human milk.

We measured concentrations of the gastrointestinal protective peptides Trefoil factors in human milk. By the use of in-house ELISA we detected high amounts of TFF3, less TFF1 and virtually no TFF2 in human breast milk obtained from 46 mothers with infants born extremely preterm (24-27 wk gestation), preterm (28-37 wk gestation), and full term (38-42 wk gestation). Samples were collected during the first, second, third to fourth weeks and more than 4 wks postpartum.

Impact of maternal endothelial nitric oxide synthase gene polymorphisms on blood pressure, protein excretion and fetal outcome in pregnancy.

A genetic association study was conducted to assess whether genetically determined alterations of the nitric oxide system are associated with clinical markers of pre-eclampsia. A large number of Caucasian women were consecutively included after delivery and genotyped for the endothelial nitric oxide synthase gene (NOS3) polymorphisms G894T, T789C (n=1502) and intron 4a/b (n=2186). There are no significant differences in mean blood pressure (BP), protein excretion or new-onset peripheral oedema between any of the genotypes over the course of pregnancy.

Formation of reactive oxygen species in lung alveolar cells: effect of vitamin E deficiency.

Reactive oxygen species (ROS) play an important role in the pathogenesis of numerous pulmonary diseases. Various mainly membrane-bound ROS-generating processes exist in alveolar cells. Vitamin E (vit.
