Somatic Development Disorders in Children and Adolescents Affected by Syndromes and Diseases Associated with Neurodysfunction and Hydrocephalus Treated/Untreated Surgically.

Int J Environ Res Public Health 2022 May 7;19(9). Epub 2022 May 7.

Institute of Health Sciences, University of Rzeszow, 35-959 Rzeszów, Poland.

Background: This study was conducted to evaluate the co-occurrence of hydrocephalus treated/untreated surgically and congenital nervous system disorders or neurological syndromes with symptoms visible since childhood, and with somatic development disorders, based on significant data obtained during admission to a neurological rehabilitation unit for children and adolescents.

Methods: The study applied a retrospective analysis of data collected during hospitalization of 327 children and adolescents, aged 4-18 years, all presenting congenital disorders of the nervous system and/or neurological syndromes associated with at least one neurodysfunction that existed from early childhood. To allow the identification of individuals with somatic development disorders in the group of children and adolescents with hydrocephalus treated/untreated surgically, the adopted criteria considered the z-score values for body height, body weight, head circumference, body mass index, and head circumference index.

Transporters in drug development: International transporter consortium update on emerging transporters of clinical importance.

Clin Pharmacol Ther 2022 May 13. Epub 2022 May 13.

Department of Pharmaceutical Sciences, University of Toronto, Leslie Dan Faculty of Pharmacy, 144 College Street, Toronto, ON, M5S 3M2, Canada.

During its 4 transporter workshop in 2021, the International Transporter Consortium (ITC) provided updates on emerging clinically relevant transporters for drug development. Previously highlighted and new transporters were considered based on up-to-date clinical evidence of their importance in drug-drug interactions and potential for altered drug efficacy and safety, including drug-nutrient interactions leading to nutrient deficiencies. For the first time, folate transport pathways (PCFT, RFC, and FRα) were examined in-depth as a potential mechanism of drug-induced folate deficiency and related toxicities (e. Read More

FASEB J 2022 May;36 Suppl 1

Department of Anatomy and Cell Biology, University of Iowa, Iowa City, IA.

Craniofacial deformities, specifically non-syndromic cleft lip with or without palate (NSCL/P), are among the most common class of birth defects. Complex interactions between genetic and environmental factors contribute to the development of NSCL/P. Many genes have been associated with this disease, including ARHGAP29. Read More

Craniofacial Defects Persist in Eftud2 mutant mice with P53 Deletion.

FASEB J 2022 May;36 Suppl 1

Anatomy and Cell Biology, McGill University, Montreal, QC.

EFTUD2 is mutated in patients with mandibulofacial dysostosis with microcephaly (MFDM). We previously showed that homozygous deletion of Eftud2 in neural crest cells causes brain and craniofacial malformations, affecting the same precursors as in MFDM patients. This phenotype was partially rescued by inhibition of the P53-pathway using pifithrin-α. Read More

Tight junction membrane protein's role in neural tube defects.

FASEB J 2022 May;36 Suppl 1

Brigham Young University, Springville, UT.

More than 300,000 infants worldwide are born with neural tube defects (NTD), making it the second most common birth defect in the world. Many genetic and environmental factors have been identified as drivers of NTDs, some of which have been tied to damage of tight junctions (TJ), which are critical for the success of neural tube folding. Claudins (CLDN), occludin (OCLN) and junctional adhesion molecules (JAMs) are essential components of the TJ and are key players in its function. Read More

Effects of spliceosomal mutations on brain patterning and morphogenesis.

FASEB J 2022 May;36 Suppl 1

Human Genetics, McGill University, Montreal, QC.

The major spliceosome consists of U1, U2, U5, and U4/U6 small nuclear ribonucleoprotein (snRNPs), and each snRNP has distinct and sequential roles during the mRNA splicing process. Mutations in the core components of the spliceosome are associated with brain and neurological defects. The goal of this study is to examine the role of three core spliceosomal components, SNRPB, SF3B4, and EFTUD2, in brain patterning and morphogenesis, and whether or not they are required in the neural tube or neural crest cells for brain development.

Micronutrient Balance Related to Neural Tube Defects and Prevention.

FASEB J 2022 May;36 Suppl 1

University of Colorado Boulder, Boulder, CO.

Neural tube defects (NTDs) are a common congenital disorder resulting from failed neural tube formation, the precursor of the brain and spinal cord. The complex etiology of NTDs involve both genetic and environmental factors, thus investigating gene-environment interactions is critical to understanding how NTDs occur or how NTDs may be prevented. For example, iron deficiency is among the most prevalent micronutrient deficiencies in pregnancy and there is evidence that iron deficiency can increase the risk of NTDs. Read More

Department of Orthopaedic Surgery, UConn Health, Farmington, Connecticut, United States of America.

Notch receptors are determinants of cell fate and function, and play an important role in the regulation of bone development and skeletal remodeling. Lateral Meningocele Syndrome (LMS) is a monogenic disorder associated with NOTCH3 pathogenic variants that result in the stabilization of NOTCH3 and a gain-of-function. LMS presents with neurological developmental abnormalities and bone loss. Read More

In-utero Diagnosis of Double Encephalocele - Imaging Features and Review of Literature.

J Radiol Case Rep 2021 Dec 1;15(12):1-9. Epub 2021 Dec 1.

Department of Radiology, Penn State Health Milton S. Hershey Medical Center, Hershey, PA, USA.

Encephalocele is protrusion of brain parenchyma through a defect in the cranium. It is classified into various types based on the defect location: sincipital (fronto-ethmoidal), basal (trans-sphenoidal, spheno-ethmoidal, trans-ethmoidal, and spheno-orbital), occipital and parietal. Double encephaloceles are very rare with only a handful of cases reported in the literature and most of these cases involved either occipital or sub-occipital region. Read More

Pathogenesis of neural tube defects: The regulation and disruption of cellular processes underlying neural tube closure.

WIREs Mech Dis 2022 May 3:e1559. Epub 2022 May 3.

Molecular Cellular Developmental Biology, University of Colorado, Boulder, Colorado, USA.

Neural tube closure (NTC) is crucial for proper development of the brain and spinal cord and requires precise morphogenesis from a sheet of cells to an intact three-dimensional structure. NTC is dependent on successful regulation of hundreds of genes, a myriad of signaling pathways, concentration gradients, and is influenced by epigenetic and environmental cues. Failure of NTC is termed a neural tube defect (NTD) and is a leading class of congenital defects in the United States and worldwide. Read More

Nutrient Transporter Gene Expression in the Early Conceptus-Implications From Two Mouse Models of Diabetic Pregnancy.

Front Cell Dev Biol 2022 11;10:777844. Epub 2022 Apr 11.

Regulation of Gene Expression, Pennington Biomedical Research Center, Louisiana State University System, Baton Rouge, LA, United States.

Maternal diabetes in early pregnancy increases the risk for birth defects in the offspring, particularly heart, and neural tube defects. While elevated glucose levels are characteristic for diabetic pregnancies, these are also accompanied by hyperlipidemia, indicating altered nutrient availability. We therefore investigated whether changes in the expression of nutrient transporters at the conception site or in the early post-implantation embryo could account for increased birth defect incidence at later developmental stages.
