BACKGROUND: Prematurity carries a high risk of mortality and sequelae, altering the bonding process and leading to repercussions in terms of attachment. OBJECTIVE: To assess the type of attachment in children under 32weeks' gestational age (GA) or below 1500g, in hospitals where development-centred care has been implemented and to study the association between various types of attachment and certain neonatal and family characteristics. METHOD: Children <1500g or <32weeks GA who were born or admitted before 48h of life to one of two hospitals in Madrid between January and December 2012 were candidates for the study...

BACKGROUND: Myocardial tolerance to ischemia is influenced by age and preoperative cyanosis through unknown mechanisms and significantly affects postoperative outcomes. Cytochrome c oxidase (CcOx), the terminal enzyme of the mitochondrial electron transport chain, may play a role in the susceptibility to ischemic-reperfusion (IR) injury. Our study aimed at investigating changes in human myocardial CcOx activity based on age and preoperative oxygen saturation to understand its role in transition from neonatal to mature myocardium and hypoxic conditions...

RATIONALE: Cardiac progenitor cells are an attractive cell type for tissue regeneration but their mechanism for myocardial remodeling is still unclear. OBJECTIVE: This investigation determines how chronological age influences the phenotypic characteristics and the secretome of human cardiac progenitor cells (CPCs), as well as their potential to recover injured myocardium. METHODS AND RESULTS: Adult (aCPCs) and neonatal (nCPCs) cells were derived from patients more than 40 years or less than one month of age, respectively, and their functional potential was determined in a rodent myocardial infarction (MI) model...

Effects observed within one generation disregard potential detrimental effects that may appear across generations. Previously we have developed a two generation Daphnia magna reproduction test using the OECD TG 211 protocol with a few amendments, including initiating the second generation with third brood neonates produced from first generation individuals. Here we showed the results of an inter-laboratory calibration exercise among 12 partners that aimed to test the robustness and consistency of a two generation Daphnia magna reproduction test...

STUDY QUESTION: Is blastocyst transfer safe when compared to cleavage stage embryo transfer regarding obstetric and perinatal outcomes? SUMMARY ANSWER: The clinical equipoise between blastocyst and cleavage stage embryo transfer remains as the evidence associating blastocyst transfer with some adverse perinatal outcomes is of low/very low quality. WHAT IS KNOWN ALREADY: Extended embryo culture to the blastocyst stage provides some theoretical advantages and disadvantages...

OBJECTIVE: The critically ill, premature patients of neonatal intensive care units are susceptible to venous thrombosis, an adverse event associated with short- and long-term morbidity. Venous thrombosis is frequently treated with low-molecular-weight heparins (LMWHs) such as enoxaparin, but optimal dosing of LMWH must balance the morbidity of venous thrombosis with the potential adverse affects of anticoagulation. The optimal dosing of enoxaparin for premature infants is unclear. The objective of this study was to describe enoxaparin therapy and follow-up in critically ill neonates diagnosed with venous thrombosis...

Short-chain enoyl-CoA hydratase (SCEH) is a mitochondrial enzyme involved in the oxidation of fatty acids and the catabolic pathway of valine and, to a lesser extent, isoleucine. Deficiency of this enzyme was recently shown to cause an early childhood Leigh syndrome phenotype. The few reported patients were compound heterozygotes for two missense or missense with truncating variants in ECHS1 that encodes SCEH. We describe two siblings with severe refractory lactic acidosis and death within the first 2 days of life...

Targeting the androgen receptor (AR) pathway prolongs survival in patients with prostate cancer, but resistance rapidly develops. Understanding this resistance is confounded by a lack of noninvasive means to assess AR activity in vivo. We report intracellular accumulation of a secreted antigen-targeted antibody (SATA) that can be used to characterize disease, guide therapy, and monitor response. AR-regulated human kallikrein-related peptidase 2 (free hK2) is a prostate tissue-specific antigen produced in prostate cancer and androgen-stimulated breast cancer cells...

BACKGROUND AND AIMS: Oxidative stress and the generation of reactive oxygen/nitrogen species has a known significant impact on intrauterine fetal growth and the risk of metabolic diseases in adulthood. Compounds accumulated in fetal meconium may be a source of information about the oxidoreductive status during the intrauterine development. Three metal-containing proteins ceruloplasmin (CP), lactoferrin (LF) and myeloperoxidase (MPO) constitute the complementary panel modulating oxidative stress...

BACKGROUND: Infants with neonatal encephalopathy (NE) of hypoxic-ischaemic origin are at risk of oxidative and ischaemia-reperfusion injury, which may induce abnormal inflammatory responses involving excessive cytokine production and release in serum and cerebrospinal fluid (CSF). Systemic inflammation is found in infants with NE, and we therefore were interested in cytokines associated with hypoxia, including vascular endothelial growth factor (VEGF) and erythropoietin (Epo). OBJECTIVE: To investigate the relationship between Epo, VEGF levels, brain injury and outcome in a group of term infants exposed to perinatal asphyxia (PA) compared to controls...

Senecavirus A (SVA) is an emerging picornavirus that has been recently associated with vesicular disease and neonatal mortality in swine. Many aspects of SVA infection biology and pathogenesis, however, remain unknown. Here the pathogenesis of SVA was investigated in finishing pigs. Animals were inoculated via the oronasal route with a contemporary SVA strain SD15-26 and monitored for clinical signs and lesions associated with SVA infection. Viremia was assessed in serum and virus shedding monitored in oral and nasal secretions and feces by real-time reverse transcriptase PCR (RT-qPCR) and/or virus isolation...

BACKGROUND: Functional Fibrinogen assay of the Thromboelastography (FFTEG), a whole blood viscoelastic hemostatic assay, has been used to estimate fibrinogen levels in adult patients undergoing major surgery but its performance in pediatric patients undergoing cardiac surgery requires evaluation. In this study, we evaluate the correlation between FFTEG parameters and standard laboratory tests for fibrinogen and platelet counts before and after cardiopulmonary bypass in children undergoing repair for congenital heart disease...

The association of hypophosphataemic rickets with verrucous epidermal naevus (EN) and elevated fibroblast growth factor 23 levels is known as cutaneous-skeletal hypophosphataemia syndrome (CSHS), and can be caused by somatic activating mutations in RAS genes. We report a unique patient with CSHS associated with giant congenital melanocytic naevus (CMN), neurocutaneous melanosis and EN syndrome, manifesting as facial linear sebaceous naevus, developmental delay and ocular dermoids. An activating mutation Q61R in the NRAS gene was found in affected skin and ocular tissue but not blood, implying that the disparate manifestations are due to a multilineage activating mutation (mosaic RASopathy)...

In mice, generation of autoreactive CD5(+) B cells occurs as a consequence of BCR signaling induced by (self)-ligand exposure from fetal/neonatal B-1 B cell development. A fraction of these cells self-renew and persist as a minor B1 B cell subset throughout life. Here, we show that transfer of early generated B1 B cells from Eμ-TCL1 transgenic mice resulted in chronic lymphocytic leukemia (CLL) with a biased repertoire, including stereotyped BCRs. Thus, B1 B cells bearing restricted BCRs can become CLL during aging...

Huntington's disease (HD) patients suffer from progressive and debilitating motor dysfunction. Previously, we discovered reduced skeletal muscle chloride channel (ClC-1) currents, inwardly rectifying potassium (Kir) channel currents, and membrane capacitance in R6/2 transgenic HD mice. The ClC-1 loss-of-function correlated with increased aberrant mRNA processing and decreased levels of full-length ClC-1 mRNA (Clcn1 gene). Physiologically, the resulting muscle hyperexcitability may help explain involuntary contractions of HD...

In Exp. 1, 56 gestating sows (PIC 1050; 35 d postinsemination) were used in a 30-d trial to determine serum 25(OH)D response to increasing concentrations of dietary vitamin D. Sows were randomly allotted to 1 of 7 dietary D treatments (200, 800, 1,600, 3,200, 6,400, 12,800, or 25,600 IU of added D per kilogram of complete diet) with 8 sows per treatment. Increasing D increased (quadratic; < 0.001) serum 25(OH)D with the response depicted by the prediction equation: serum 25(OH)D, ng/mL = 35.1746 + (0.002353 × dietary D, IU/d) - (0...

Hyperprolificacy in modern pig breeds has led to increased use of artificial rearing and formula feeding of neonatal piglets, which may change their intestinal bacterial ecophysiology. Here, newborn piglets ( = 8 per group) were fed a bovine milk-based formula (FO) or allowed to suckle their mothers (sow milk [SM]) for 2 wk, and digesta samples from the stomach, jejunum, and colon were subsequently analyzed for enzyme activities, bacterial metabolites, and 16S rRNA transcripts of bacterial groups by quantitative real-time PCR...

BACKGROUND: Respiratory failure is a leading cause of neonatal mortality in the developing world. Bubble continuous positive airway pressure (bCPAP) is a safe, effective intervention for infants with respiratory distress and is widely used in developed countries. Because of its high cost, bCPAP is not widely utilized in low-resource settings. We evaluated the performance of a new bCPAP system to treat severe respiratory distress in a low resource setting, comparing it to nasal oxygen therapy, the current standard of care...

There is intense interest in identifying modifiable risk factors associated with autism-spectrum disorders (ASD). Autism-related traits, which can be assessed in a continuous fashion, share risk factors with ASD, and thus can serve as informative phenotypes in population-based cohort studies. Based on the growing body of research linking gestational vitamin D deficiency with altered brain development, this common exposure is a candidate modifiable risk factor for ASD and autism-related traits. The association between gestational vitamin D deficiency and a continuous measure of autism-related traits at ~6 years (Social Responsiveness Scale; SRS) was determined in a large population-based cohort of mothers and their children (n=4229)...
