Postmortem whole-genome sequencing on a dried blood spot identifies a novel homozygous SUOX variant causing isolated sulfite oxidase deficiency.

Cold Spring Harb Mol Case Stud 2021 Jun 11;7(3). Epub 2021 Jun 11.

Rady Children's Institute for Genomic Medicine, San Diego, California 92123, USA.

Rapid whole-genome sequencing (rWGS) has shown that genetic diseases are a common cause of infant mortality in neonatal intensive care units. Dried blood spots collected for newborn screening allow investigation of causes of infant mortality that were not diagnosed during life. Here, we present a neonate who developed seizures and encephalopathy on the third day of life that was refractory to antiepileptic medications. Read More

Does Severity of Brain Injury on Magnetic Resonance Imaging Predict Short-Term Outcome in Neonates Who Received Therapeutic Hypothermia?

Am J Perinatol 2021 Jun 8. Epub 2021 Jun 8.

Neonatal-Perinatal Medicine, Children's Hospital of Michigan, Detroit, Michigan.

Objective:  The National Institute of Child Health and Human Development (NICHD) magnetic resonance imaging (MRI) pattern of brain injury is a known biomarker of childhood outcome following therapeutic hypothermia for neonatal hypoxic-ischemic encephalopathy (HIE). However, usefulness of this classification has not been evaluated to predict short-term outcomes. The study aimed to test the hypothesis that infants with NICHD MRI pattern of severe hypoxic-ischemic brain injury will be sicker with more severe asphyxia-induced multiorgan dysfunction resulting in prolonged length of stay (LOS) following therapeutic hypothermia.

Biallelic variants in VPS50 cause a neurodevelopmental disorder with neonatal cholestasis.

Brain 2021 May 26. Epub 2021 May 26.

Institute of Human Genetics, University Medical Center Hamburg-Eppendorf, 20246 Hamburg, Germany.

Golgi-associated retrograde protein (GARP) and endosome-associated recycling protein (EARP) complexes are membrane-tethering heterotetramers located at the trans-Golgi network and recycling endosomes, respectively. GARP and EARP share the three subunits VPS51, VPS52, and VPS53, while VPS50 is unique to EARP and VPS54 to GARP. Retrograde transport of endosomal cargos to the TGN is mediated by GARP and endocytic recycling by EARP. Read More

Clinical, biological and electroencephalographic monitoring of newborns with neurological risk in the Neonatal Intensive Care Unit.

Exp Ther Med 2021 Jul 13;22(1):760. Epub 2021 May 13.

Neonatology and Puericulture Department, 'Victor Babeş' University of Medicine and Pharmacy of Timisoara, 300041 Timisoara, Romania.

Newborns admitted to the Neonatal Intensive Care Unit (NICU) require increased attention regarding neurological assessment and monitoring, due to immaturity or certain conditions that occur during the perinatal and neonatal period. Hypoxic-ischemic encephalopathy (HIE) following perinatal asphyxia is one of the most studied clinical conditions due to the risk of medium- and long-term neurobehavioral outcome. We studied 43 newborns with HIE, for all 3 degrees of impairment, performed amplitude-integrated electroencephalography (aEEG) in the first hours of life and collected common laboratory tests, following serum glycemia at admission and creatinine, creatine kinase (CK) and lactate dehydrogenase (LDH) at admission and in the 3 day of life.

Clinical profile, aetiology, short-term outcome and predictors of poor outcome of neonatal seizures among out-born neonates admitted to a neonatal unit in Paediatric emergency of a tertiary care hospital in North India: A prospective observational study.

Trop Doct 2021 May 21:494755211016226. Epub 2021 May 21.

Assistant Professor, Division of Paediatric Critical Care, Department of Paediatrics, Advanced Paediatric Centre, Postgraduate Institute of Medical Education and Research (29751PGIMER), Chandigarh, India.

Neonatal seizures are common manifestations of several neurological or systemic disorders and associated with high morbidity, mortality and poor short- and long-term developmental outcomes. It is important to determine the aetiology and factors that determine the poor outcome, more so in a newly developed setting. The early detection of predictors of poor outcome will help in planning acute management, counselling, follow-up and rehabilitation services. Read More

Altered hippocampal dendritic spine maturation after hypoxia-induced seizures in neonatal rats.

Mol Cell Neurosci 2021 Jun 18;113:103629. Epub 2021 May 18.

Department of Neurology, Perelman School of Medicine, University of Pennsylvania, Philadelphia, PA, United States of America. Electronic address:

Cognitive comorbidities often follow early-life seizures (ELS), especially in the setting of autism and other neurodevelopmental syndromes. However, there is an incomplete understanding of whether neuronal and synaptic development are concomitantly dysregulated. We have previously shown that hypoxia-induced seizures (HS) in postnatal day (P)10 rats increase acute and later-life hippocampal glutamatergic neurotransmission and spontaneous recurrent seizures, and impair cognition and behavior.
