BACKGROUND: The use of neonatal 3-lead electrocardiograms (Neo-ECG) is suggested as a method for the assessment of heart rate (HR) in neonatal resuscitation, but primary childbirth facilities (i.e., maternity clinics or maternity homes) are not sufficiently equipped for this. The objective of this study was to confirm the potential of using a handheld fetal Doppler device (FDD), widely used to assess HR in labor room resuscitation, and to compare its equivalency to Neo-ECG. METHODS: In low-risk full-term infants, HR was measured 5 times/minute in minutes 1-5 postpartum using the FDD and Neo-ECG, and their equivalence was compared...

The authors present an overview of lower urinary tract obstruction (LUTO) in the fetus with a particular focus on the insult to the developing renal system. Diagnostic criteria along with the challenges in estimating long-term prognosis are reviewed. A proposed prenatal LUTO disease severity classification to guide management decisions with fetal intervention to maintain or salvage in utero and neonatal pulmonary and renal function is also discussed. Stage I LUTO (mild form) is characterized by normal amniotic fluid index after 18 weeks, normal kidney echogenicity, no renal cortical cysts, no evidence of renal dysplasia, and favorable urinary biochemistries when sampled between 18 and 30 weeks; prenatal surveillance is recommended...

Objectives Each year in the U.S., approximately 7200 infants are born with a critical congenital heart defect (CCHD). The Georgia Department of Public Health (DPH) mandated routine screening for CCHD starting January 2015. The current study evaluated hospital performance of the mandated CCHD screenings in Georgia. Methods Utilizing the DPH newborn screening surveillance system, data from 6 months before and after the mandate were analyzed for reports submitted and positive CCHD screening results. Chi square tests of independence were performed to examine the association between reporting of results for CCHD screening after the mandate and hospital nursery level [level I (well-baby/newborn); level II (special care); level III (neonatal intensive care unit-NICU)] and NICU submissions...

Current therapies for heart failure after myocardial infarction are limited and non-curative. Although regenerative approaches are receiving significant attention, clinical efforts that involve transplantation of presumed stem and progenitor cells have largely failed to deliver. Recent studies of endogenous heart regeneration in model organisms, such as zebrafish and neonatal mice, are yielding mechanistic insights into the roles of cardiomyocyte proliferation, resident stem cell niches, neovascularization, the immune system and the extracellular matrix...

REVIEW
Wayne R Cohen
The assessment of uterine contractions is important in clinical decision-making, but the precise role for appraising contractions remains controversial. Four clinical approaches to assessing contractions are available: manual palpation; intrauterine pressure determination; external tocodynamometry; and electrohysterography. Palpation is inexpensive and harmless but requires the constant bedside presence of a trained observer. Intrauterine pressure measurement is considered the most sensitive and specific technique, and has become the standard by which other methods are judged; however, its quantitative measurements are not always precise or reproducible...

Cardiovascular diseases are a leading cause of death, in part due to limitations of existing models of the myocardium. Myocardium consists of aligned, contractile cardiac myocytes interspersed with fibroblasts that synthesize extracellular matrix (ECM). The cellular demographics and biochemical and mechanical properties of the ECM remodel in many different cardiac diseases. However, the impact of diverse cellular and extracellular remodeling on the contractile output of the myocardium are poorly understood...

BACKGROUND: To evaluate changes in neonatal resuscitation and postnatal care following Helping Babies Breathe (HBB) training at a community hospital in rural Honduras. We hypothesized that HBB training would improve resuscitation and essential newborn care interventions. METHODS: Direct observation and video recording of delivery room care spanned before and after an initial HBB workshop held in August 2013. Rates of essential newborn care interventions were compared in resuscitations performed by individuals who had and had not received HBB training, and run charts recording performance of newborn care practices over time were developed...

Murine astrovirus (MuAstV) is a recently identified, widespread infection among laboratory mice. Our goal was to determine the duration of MuAstV infection, susceptibility of pups, and efficacy of soiled-bedding sentinels and environmental monitoring. Eight CD1 dams and their litters of 3-d-old pups and 8 CD1 dams and their litters of 13-d-old mice were inoculated orally with MuAstV. Neither dams nor offspring demonstrated any clinical signs, and MuAstV had little to no effect on weight gain in pups. MuAstV RNA was detected in feces from 15 of the 16 dams through postnatal day (PND) 21, and 9 dams were still shedding MuAstV at PND 42...

Angiotensin II type 2 receptor (AT2 R) deficiency in AT2 R knockout (KO) mice has been linked to congenital abnormalities of the kidney and urinary tract; however, the mechanisms by which this occurs are poorly understood. In this study, we examined whether AT2 R deficiency impaired glomerulogenesis and mediated podocyte loss/dysfunction in vivo and in vitro. Nephrin-cyan fluorescent protein (CFP)-transgenic (Tg) and Nephrin/AT2 RKO mice were used to assess glomerulogenesis, while wild-type and AT2 RKO mice were used to evaluate maturation of podocyte morphology/function...

The use of assisted reproductive technologies (ART) for the treatment of infertility has grown exponentially over the last 20 years, and now accounts for 4% of all births in Australia, and over 1 m births annually around the globe. There is consistent reporting of increased risk of adverse perinatal outcomes and birth defects following infertility treatment. However, change in practice has been stymied by critical knowledge gaps with regards to (a) the relative contribution of patient and treatment factors to adverse outcomes, (b) the independent contribution of specific contemporary treatments and treatment combinations to outcomes, (c) the impact of innovations in laboratory and clinical practice on treatment success and observed risk and (d) changes over time in patient characteristics...

Large size of individual offspring is routinely selected for in highly competitive environments, such as in low-predation populations of the Trinidadian guppy (Poecilia reticulata). Large guppy offspring outcompete their smaller conspecifics, but the functional mechanisms underlying this advantage are unknown. We measured jaw kinematics during benthic feeding and cranial musculoskeletal morphologies in neonates and juveniles from five populations of Trinidadian guppy and found that both kinematics and morphologies vary substantially with neonatal size...

miRNome expression profiling was performed in a mouse model of propionic acidemia (PA) and in patients' plasma samples to investigate the role of miRNAs in the pathophysiology of the disease and to identify novel biomarkers and therapeutic targets. PA is a potentially lethal neurometabolic disease with patients developing neurological deficits and cardiomyopathy in the long-term, among other complications. In the PA mouse liver we identified 14 significantly dysregulated miRNAs. Three selected miRNAs, miR-34a-5p, miR-338-3p and miR-350, were found upregulated in brain and heart tissues...

Hypothalamic-pituitary-adrenal axis (HPAA) dysfunction has been associated with sepsis and mortality in foals. Most studies have focused on cortisol, while other steroids have not been investigated. The objectives of this study were to characterise the adrenal steroid and steroid precursor response to disease and to determine their association with the HPAA response to illness, disease severity, and mortality in hospitalised foals. All foals (n=326) were classified by two scoring systems into three categories: based on the sepsis score (septic, sick non-septic [SNS] and healthy) and the foal survival score (Group 1: 3-18%; Group 2: 38-62%; Group 3: 82-97% likelihood of survival)...
