CD11c-expressing microglia are transient, driven by interactions with apoptotic cells.

Microglia, the parenchymal macrophage of the central nervous system serve crucial remodeling functions throughout development. Microglia are transcriptionally heterogenous, suggesting that distinct microglial states confer discrete roles. Currently, little is known about how dynamic these states are, the cues that promote them, or how they impact microglial function.

A systematic review of interventions for echolalia in autistic children.

Introduction: Echolalia, the repetition of others' speech, is a common observation in autistic people. Research has established that echolalia is functional and meaningful for many; however, some clinicians and researchers continue to characterise it as pathological and in need of reduction. The aim of this systematic review was to understand the range and impact of interventions for echolalia in autistic children.

The identification of exceptional skills in school-age autistic children: Prevalence, misconceptions and the alignment of informant perspectives.

Background: Although autism is commonly described in terms of deficits, many autistic individuals have been found to demonstrate exceptional skills. The shift to a strengths-based approach in the field of autism necessitates increased understanding of these skills.

Aims: This study examined (1) rates of exceptional skills in autistic school-age children as reported by parents and teachers, (2) associations between exceptional skills, autism severity and intellectual disability and (3) correlations between parent and teacher reports of exceptional skills.

Jarid2 promotes temporal progression of retinal progenitors via repression of Foxp1.

Transitions in competence underlie the ability of CNS progenitors to generate a diversity of neurons and glia. Retinal progenitor cells in mouse generate early-born cell types embryonically and late-born cell types largely postnatally. We find that the transition from early to late progenitor competence is regulated by Jarid2.

Non-pharmacological interventions for autistic children: An umbrella review.

The delivery of evidence-based interventions is an important part of the clinical pathway for many autistic children and their families. However, parents, practitioners, and policymakers face challenges making evidence informed decisions, due to the wide variety of interventions available and the large, and often inconsistent, body of evidence regarding their effectiveness.This is a comprehensive umbrella review, also known as a 'review of reviews', which examined the range of interventions available, the evidence for their effectiveness, and whether effects were influenced by factors relating to individual children (e.

Neuronal apoptosis drives remodeling states of microglia and shifts in survival pathway dependence.

Microglia serve critical remodeling roles that shape the developing nervous system, responding to the changing neural environment with phagocytosis or soluble factor secretion. Recent single-cell sequencing (scRNAseq) studies have revealed the context-dependent diversity in microglial properties and gene expression, but the cues promoting this diversity are not well defined. Here, we ask how interactions with apoptotic neurons shape microglial state, including lysosomal and lipid metabolism gene expression and dependence on Colony-stimulating factor 1 receptor (CSF1R) for survival.

The 2018 Global Point Prevalence Survey of antimicrobial consumption and resistance in 47 Canadian hospitals: a cross-sectional survey.

Background: Patient-level surveillance of antimicrobial use (AMU) in Canadian hospitals empowers the reduction of inappropriate AMU and was piloted in 2017 among 14 hospitals in Canada. We aimed to describe AMU on the basis of patient-level data in Canadian hospitals in 2018 in terms of antimicrobial prescribing prevalence and proportions, antimicrobial indications, and agent selection in medical, surgical and intensive care wards.

Methods: Canadian adult, pediatric and neonatal hospitals were invited to participate in the standardized web-based cross-sectional Global Point Prevalence Survey of Antimicrobial Consumption and Resistance (Global-PPS) conducted in 2018.

Herpes zoster and Janus kinase inhibition in rheumatology and gastroenterology patients: managing risk and vaccination.

Patients with chronic inflammatory diseases, such as rheumatoid arthritis (RA), psoriatic arthritis (PsA) and ulcerative colitis (UC), have an increased risk of herpes zoster (HZ) infection, compared with the general population. This risk is further increased by the use of immunomodulatory therapies, with a higher incidence of HZ reported in patients receiving Janus kinase (JAK) inhibitors, compared with those receiving other immunomodulatory or biological therapies. Tofacitinib is an oral JAK inhibitor for the treatment of RA, PsA and UC.

Transcriptional repression by FEZF2 restricts alternative identities of cortical projection neurons.

Projection neuron subtype identities in the cerebral cortex are established by expressing pan-cortical and subtype-specific effector genes that execute terminal differentiation programs bestowing neurons with a glutamatergic neuron phenotype and subtype-specific morphology, physiology, and axonal projections. Whether pan-cortical glutamatergic and subtype-specific characteristics are regulated by the same genes or controlled by distinct programs remains largely unknown. Here, we show that FEZF2 functions as a transcriptional repressor, and it regulates subtype-specific identities of both corticothalamic and subcerebral neurons by selectively repressing expression of genes inappropriate for each neuronal subtype.

Prognostic value of comorbidity indices and lung diseases in early rheumatoid arthritis: a UK population-based study.

Objectives: We assessed comorbidity burden in people with RA at diagnosis and early disease (3 years) and its association with early mortality and joint destruction. The association between lung disease and mortality in RA is not well studied; we also explored this relationship.

Methods: From a contemporary UK-based population (n = 1, 475 762) we identified a cohort with incident RA (n = 6591).

Haematological abnormalities in new-onset rheumatoid arthritis and risk of common infections: a population-based study.

Objectives: To describe the prevalence of haematological abnormalities in individuals with RA at the point of diagnosis in primary care and the associations between haematological abnormalities, vaccinations and subsequent risk of common infections.

Methods: We studied 6591 individuals with newly diagnosed RA between 2004 and 2016 inclusive using the UK Royal College of General Practitioners Research and Surveillance Centre primary care database. The prevalence of haematological abnormalities at diagnosis (anaemia, neutropenia and lymphopenia) was established.

Systematic review of factors that may influence the outcomes and generalizability of parent-mediated interventions for young children with autism spectrum disorder.

Parent mediated interventions have the potential to positively influence the interactions and developmental outcomes of children with autism spectrum disorder (ASD). However, a range of factors relating to children, parents and caregivers, and study design may impact on outcomes and thus the generalizability of these interventions to the broader community. The objective of this review was to examine factors that may influence the feasibility, appropriateness, effectiveness, and generalizability of parent mediated interventions for children with ASD.

The Developmental Behaviour Checklist (DBC) Profile in Young Children on the Autism Spectrum: The Impact of Child and Family Factors.

High levels of emotional/behavioural difficulties are frequently reported in children on the autism spectrum. However, given the diversity in profiles, there is a need to explore such behaviours in relation to individual factors. Parents of 130 children aged 4-5 on the autism spectrum completed measures of behaviour and adaptive behaviour.

Developmental Apoptosis Promotes a Disease-Related Gene Signature and Independence from CSF1R Signaling in Retinal Microglia.

Microglia have important remodeling functions in neurodevelopment, aging, and disease, with evidence for molecular diversity. However, the signaling pathways and environmental cues that drive diverse states of microglia are incompletely understood. We profiled microglia of a discrete developing CNS region, the murine retina.

Telehealth and autism: Are telehealth language assessments reliable and feasible for children with autism?

Background: Access to timely and appropriate speech-language pathology (SLP) services is a significant challenge for many families. Telehealth has been used successfully to treat a range of communication disorders in children and adults. Research examining the use of telehealth for children with autism has focused largely on diagnosis, parent-implemented interventions, and behavioural interventions involving interactions between clinicians and parents.

Telehealth and autism: A systematic search and review of the literature.

Purpose: Research interest in telehealth and autism spectrum disorder (ASD) has grown. There is a need to review the literature to allow speech-language pathologists (SLPs) and other service providers to consider applicability to their settings. The aim of this review was to examine the nature and outcomes of studies examining telehealth assessment and/or intervention in ASD.

C8orf46 homolog encodes a novel protein Vexin that is required for neurogenesis in Xenopus laevis.

Neural basic helix-loop helix (bHLH) transcription factors promote progenitor cell differentiation by activation of downstream target genes that coordinate neuronal differentiation. Here we characterize a neural bHLH target gene in Xenopus laevis, vexin (vxn; previously sbt1), that is homologous to human c8orf46 and is conserved across vertebrate species. C8orf46 has been implicated in cancer progression, but its function is unknown.

From Retina to Stem Cell and Back Again: Memories of a Chromatin Journey.

The use of retinal organoids requires efficient differentiation from induced pluripotent stem cells (iPSCs). In this issue of Cell Reports, Wang et al. (2018) examine how the chromatin landscape after iPSC programming predicts their ability to differentiate into retinal tissue.

Protocol for a prospective longitudinal study investigating the participation and educational trajectories of Australian students with autism.

Introduction: Autism is associated with high cost to individuals, families, communities and government. Understanding educational and participation trajectories during the school years, and factors influencing these, is fundamental to reducing financial and personal costs. The primary aim of this study is to document the trajectories of Australian students with autism during their education.

Anxiety-related symptomatology in young children on the autism spectrum.

Anxiety symptomatology is frequently reported in autistic children, and the prevalence of anxiety disorder is estimated at around 40%. However, most studies have focused upon children of age 8 years or above, so little is known about early signs of anxiety in younger children with autism. This study sought to describe anxiety-related symptomatology in 95 5- to 6-year-old autistic children using the Anxiety Scale for Children with Autism Spectrum Disorder.

The Oral Narrative Comprehension and Production Abilities of Verbal Preschoolers on the Autism Spectrum.

Purpose: This study described the oral narrative comprehension and production skills of verbal preschool-age children on the autism spectrum and investigated correlations between oral narrative ability and norm-referenced language test performance.

Method: Twenty-nine preschool-age children (aged 4;0-5;9 years;months) with autism, who obtained an age-equivalent score of at least 36 months on the expressive communication subscale of the Vineland Adaptive Behavior Scales-Second Edition (Sparrow, Cicchetti, & Balla, 2005), participated. Children listened to an unfamiliar fictional narrative and answered comprehension questions afterward.

Associations between executive functions and mental health outcomes for adults with autism spectrum disorder.

Associations between executive functions (EF) and mental-health in adults with autism spectrum disorder (ASD) were examined. Forty-two adults with ASD completed measures of EF, mood and self-concept. Better concept formation and social inference skills were significantly associated with fewer anxiety symptoms.
