TL;DR: The cellular composition of the intestinal epithelium and its critical role in maintaining epithelial integrity are described and cell signaling during NEC is discussed, specifically, toll- like receptors and nucleotide oligomerization domain-like receptors.
Abstract: Necrotizing enterocolitis (NEC) is the most frequent and devastating gastrointestinal disease of premature infants. Although the precise mechanisms are not fully understood, NEC is thought to develop following a combination of prematurity, formula feeding, and adverse microbial colonization. Within the last decade, studies increasingly support an important role of a heightened mucosal immune response initiating a pro-inflammatory signaling cascade, which can lead to the disruption of the intestinal epithelium and translocation of pathogenic species. In this review, we first describe the cellular composition of the intestinal epithelium and its critical role in maintaining epithelial integrity. We then discuss cell signaling during NEC, specifically, toll-like receptors and nucleotide oligomerization domain-like receptors. We further review cytokines and cellular components that characterize the innate and adaptive immune systems and how they interact to support or modulate NEC development.

TL;DR: Multi-center research programs focused on PCD in North America and Europe have been crucial for PCD gene discovery, advancing the understanding of the natural history of PCD and launching multi-center clinical trials.
Abstract: Primary ciliary dyskinesia (PCD) is a genetic disorder of motile cilia. Clinical features include chronic oto-sinopulmonary disease, laterality defects, and male fertility reflecting impaired function of respiratory cilia in the upper and lower respiratory tracts, nodal cilia in the embryonic node and sperm tails, respectively. Recent studies have identified over 40 PCD-associated genes that encode proteins involved in ciliary biogenesis, assembly, structure, or function. Mutations in these genes account for approximately 70% of PCD cases; therefore, further gene discovery is expected. The diagnosis of PCD is challenging because no single test has the required diagnostic accuracy. Recent efforts have focused on standardizing and validating a panel of tests (including assessment for key clinical features, nasal nitric oxide measurement, ciliary ultrastructure analysis, and PCD genetic testing) to be used at PCD Centers to accurately diagnose PCD. Multi-center research programs focused on PCD in North America and Europe have been crucial for PCD gene discovery, advancing our understanding of the natural history of PCD and launching multi-center clinical trials.

TL;DR: It is suggested that some of the other features present in more than one patient with deletion, including hypotonia, sleep apnea, chronic constipation, gastroesophageal and vesicoureteral refluxes, epilepsy, ataxia, dysphagia, nystagmus, and ptosis may result from deletion of the CHAT gene, encoding choline acetyltransferase, and the SLC18A3 gene.
Abstract: We report 24 unrelated individuals with deletions and 17 additional cases with duplications at 10q11.21q21.1 identified by chromosomal microarray analysis. The rearrangements range in size from 0.3 to 12 Mb. Nineteen of the deletions and eight duplications are flanked by large, directly oriented segmental duplications of >98% sequence identity, suggesting that nonallelic homologous recombination (NAHR) caused these genomic rearrangements. Nine individuals with deletions and five with duplications have additional copy number changes. Detailed clinical evaluation of 20 patients with deletions revealed variable clinical features, with developmental delay (DD) and/or intellectual disability (ID) as the only features common to a majority of individuals. We suggest that some of the other features present in more than one patient with deletion, including hypotonia, sleep apnea, chronic constipation, gastroesophageal and vesicoureteral refluxes, epilepsy, ataxia, dysphagia, nystagmus, and ptosis may result from deletion of the CHAT gene, encoding choline acetyltransferase, and the SLC18A3 gene, mapping in the first intron of CHAT and encoding vesicular acetylcholine transporter. The phenotypic diversity and presence of the deletion in apparently normal carrier parents suggest that subjects carrying 10q11.21q11.23 deletions may exhibit variable phenotypic expressivity and incomplete penetrance influenced by additional genetic and nongenetic modifiers.

TL;DR: Brief interventions may shift parental attitudes toward using less physical punishment and have implications for improving anticipatory guidance within primary care and early education.
Abstract: Ninety-six parents in a preschool and pediatric clinic participated in a randomized study of a brief parenting intervention. The Attitudes Toward Spanking (ATS) scale was measured at baseline, and, on average, 4 months postintervention. Higher ATS scores are correlated with increased use of physical punishment. In the intervention group, there was a 2.7-point decrease in the ATS score at follow-up compared with baseline (P = 0.01). There was no decrease in the ATS in the control group. Brief interventions may shift parental attitudes toward using less physical punishment and have implications for improving anticipatory guidance within primary care and early education.

TL;DR: The consistent finding of prostatic epithelium in tissue recombinants of trigone epithelio and fetal urogenital sinus mesenchyma reinforces the hypothesis that the trigone is derived from the endoderm and not from the mesoderm, as commonly accepted.
