OBJECTIVE: To determine the clinical profile and outcome of critically ill children presenting to a paediatric ED in a lower middle-income country. METHODS: We performed a retrospective analysis of children (<14 years) presenting to the ED of the National Institute of Child Health, Karachi, between January and December 2014 who were assigned to acuity 1 (requiring immediate life-saving interventions) according to the Emergency Severity Index. Data included demographic variables, presenting complaints, interventions and outcomes in the ED...

Insulin resistance participates in the glycaemic control disruption in type 2 diabetes mellitus (T2DM), by reducing muscle glucose influx and increasing liver glucose efflux. GLUT4 (Slc2a4 gene) and GLUT2 (Slc2a2 gene) proteins play a fundamental role in the muscle and liver glucose fluxes, respectively. Resveratrol is a polyphenol suggested to have an insulin sensitizer effect; however, this effect, and related mechanisms, have not been clearly demonstrated in T2DM. We hypothesized that resveratrol can improve glycaemic control by restoring GLUT4 and GLUT2 expression in muscle and liver...

This article discusses a quality improvement project in the context of paediatric inter-hospital transportation. The project was set in a large university teaching hospital in Ireland. Risk assessment on the clinical site revealed a gap in the application of best national and international standards in inter-hospital transportation practice. A project was undertaken to explore current paediatric transport services and respond to a clinical service deficit. Consequently, the proposed quality improvement initiative proposes a universal Paediatric Advanced Life Support Programme (PALS) to upskill and enhance the required clinical standards and competencies of neonatal nurses...

Research examining the direct and indirect ecological effects of nanomaterials in aquatic ecosystems is important for developing a more realistic understanding of the environmental implications of nanotechnology. Copper oxide nanoparticles (CuO NPs) are being used extensively in many industries but are considered highly toxic to aquatic species residing in surface waters. Few studies have addressed whether CuO NPs can be transferred through the aquatic food chain, and if such indirect exposure to nanomaterials impacts their toxicity...

The paediatric intensive care unit (PICU) provides care to critically ill neonates, infants and children. These patients are vulnerable and susceptible to the environment surrounding them, yet there is little information available on indoor air quality and factors affecting it within a PICU. To address this gap in knowledge we conducted continuous indoor and outdoor airborne particle concentration measurements over a two-week period at the Royal Children's Hospital PICU in Brisbane, Australia, and we also collected 82 bioaerosol samples to test for the presence of bacterial and viral pathogens...

Development of the gastrointestinal tract and immune system can be modulated by the gut microbiota. Establishment of the intestinal microbiota, in its turn, is affected by host- and environmental factors. As such, development of the gut microbiota is greatly impacted in preterm infants, who have an immature gut and are exposed to factors like hospitalisation, caesarean section, antibiotics, and respiratory support.</p> <p>Design: We analysed faecal microbiota composition and activity of ten preterm infants (gestational age 25-30 weeks; birthweight 630-1750 gram) during the first six postnatal weeks through metaproteomics (LC-MS/MS) and 16S-rRNA gene sequencing...

Many membrane cargoes undergo endocytosis and intracellular recycling to the plasma membrane via the early endosomes and the recycling endosomes. However whether specific sorting signals are required for transport from early endosomes to recycling endosomes is not known and the current view is that transport to the recycling endosomes is by a passive default process. Here we show that the cytoplasmic tail of the neonatal Fc receptor (FcRn) contains discrete signals for endocytosis and for sorting to the recycling endosomes...

<i>Inherited neurodegenerative disorders are debilitating diseases that occur across different species, such as the domestic dog (Canis lupus familiaris), and many are caused by mutations in the same genes as corresponding human conditions. In the present study, we report an inherited neurodegenerative condition, termed 'neuronal vacuolation and spinocerebellar degeneration' (NVSD) which affects neonatal or young dogs, mainly Rottweilers, which recently has been linked with the homozygosity for the RAB3GAP1:c...

C/EBP-homologous protein (CHOP) is a ubiquitously expressed stress-inducible transcription factor robustly induced by maladaptive endoplasmic reticulum (ER) stresses in a wide variety of cells. Here we examined a novel function of Sigma 1 receptor (Sigmar1) in regulating CHOP expression under ER-stress in cardiomyocytes. We also defined Sigmar1-dependent activation of the adaptive ER-stress pathway in regulating CHOP expression. We used adenovirus-mediated Sigmar1 overexpression as well as Sigmar1 knockdown by small interfering RNA (siRNA) in neonatal rat ventricular cardiomyocytes; to induce ER-stress cardiomyocytes were treated with tunicamycin...

Breast milk is the optimal nutrient mix for infants until the age of 6 months. However, in some cases, due to genetic alterations as well as nutrient deficiencies in nursing mothers, infants may suffer from inadequate levels of micronutrients upon exclusive breastfeeding. In this respect, transient neonatal zinc deficiency (TNZD) is caused by loss-of-function mutations in the zinc transporter SLC30A2/ZnT2 gene, resulting in poor secretion of zinc into the breast milk. Consequently, infants exclusively breastfed with zinc-deficient breast milk develop severe zinc deficiency...

Biallelic mutations in SLC25A46, encoding a modified solute transporter involved in mitochondrial dynamics, have been identified in a wide range of conditions such as hereditary motor and sensory neuropathy with optic atrophy type VIB (OMIM: *610826) and congenital lethal pontocerebellar hypoplasia (PCH). To date, 18 patients from 13 families have been reported, presenting with the key clinical features of optic atrophy, peripheral neuropathy, and cerebellar atrophy. The course of the disease was highly variable ranging from severe muscular hypotonia at birth and early death to first manifestations in late childhood and survival into the fifties...

We tested the hypothesis that gestational diabetes mellitus (GDM) alters the DNA methylation pattern of the fetal serotonin transporter gene (SLC6A4), and examined the functional relevance of DNA methylation for regulation of the SLC6A4 expression in the human placenta. The study included 50 mother-infant pairs. Eighteen mothers were diagnosed with GDM and 32 had normal glucose tolerance (NGT). All neonates were of normal birth weight and born at term by planned Cesarean section. DNA and RNA were isolated from samples of tissue collected from the fetal side of the placenta immediately after delivery...

Iodide Handling Disorders lead to defects of the biosynthesis of thyroid hormones (thyroid dyshormonogenesis, TD) and thereafter congenital hypothyroidism (CH), the most common endocrine disease characterized by low levels of circulating thyroid hormones. The prevalence of CH is 1 in 2000-3000 live births. Prevention of CH is based on prenatal diagnosis, carrier identification, and genetic counseling. In neonates a complete diagnosis of TD should include clinical examination, biochemical thyroid tests, thyroid ultrasound, radioiodine or technetium scintigraphy and perchlorate discharge test (PDT)...

Atherosclerosis is a disease caused by a build-up of fatty plaques and cholesterol in the arteries. The lumen of the vessels is obliterated resulting in restricted blood supply to tissues. In ischemic conditions, the cytosolic Ca(2+) level of skeletal muscle may increase, indicating the alteration of Ca(2+) removal mechanisms. Ca(2+) is transported from cytosol into the sarcoplasmic reticulum by Ca(2+) ATPase (SERCA), with its 1a isoform expressed in adult, while its 1b isoform in neonatal and regenerating fast-twitch skeletal muscle...

BACKGROUND: Docosahexaenoic (C22:6) and arachidonic (C20:4) acids are long-chain polyunsaturated fatty acids (LC-PUFA) essential to neonatal development, being present in the glycerophospholipids of all organs, particularly the brain. In plasma, LC-PUFAs are mainly present in lipoprotein lipids, which are neutral lipids (triglycerides and cholesterol esters) and glycerophospholipids, like choline containing phosphatidylcholine (PC). PURPOSE: To guide future supplementation strategies of C22:6 and C20:4 in combination with choline, we determined the distribution of C20:4 and C22:6 between PC and neutral lipid...

Albumin is the most abundant plasma protein involved in the transport of many compounds, such as fatty acids, bilirubin, and heme. The endothelial cellular neonatal Fc receptor (FcRn) has been suggested to play a central role in maintaining the high albumin plasma levels through a cellular recycling pathway. However, direct mapping of this process is still lacking. This work presents the use of wild type and engineered recombinant albumins with either decreased or increased FcRn affinity in combination with a low or high FcRn-expressing endothelium cell line to clearly define the FcRn involvement, intracellular pathway and kinetics of albumin trafficking by flow cytometry, quantitative confocal microscopy, and an albumin-recycling assay...

Misplaced formation of microvilli to basolateral domains and intracellular inclusions in enterocytes are pathognomonic features in congenital enteropathy associated with STX3 mutation. While the demonstrated binding of Myo5b to the Rab8a and Rab11a small GTPases in vitro implicates cytoskeleton-dependent membrane sorting, the mechanisms underlying the microvillar location defect remain unclear. By selective or combinatory disruption of Rab8a and Rab11a membrane traffic in vivo, we demonstrate that transport of distinct cargo to the apical brush-border rely on either individual or both Rab regulators, whereas certain basolateral cargos are redundantly transported by both factors...

Neonatal transport is an essential part of regionalization for highly specialized neonatal intensive care. This retrospective analysis of prospectively collected data on neonatal transport activity in a large Swiss perinatal network more than 1 year, aimed to quantify this activity, to identify the needs for staff, and the demands regarding know-how and equipment. Of the 565 admissions to the tertiary neonatology clinic, 176 (31.2%) were outborn patients, transported as emergencies to the level III unit. In 71...
