Fertility preservation in pediatric central nervous system tumors: A report from the Children's Oncology Group.

The Oncofertility Consortium Pediatric Initiative Network has published recommendations about the risks of infertility due to gonadotoxic therapy. We abstracted gonadotoxic therapies from central nervous system (CNS) Children's Oncology Group (COG) protocols between 2000 and 2022. We assigned them as unknown, minimal, significant, or high levels of increased risk for gonadal dysfunction/infertility.

Measuring Cognitive Impairments Associated With Schizophrenia in Clinical Practice: Overview of Current Challenges and Future Opportunities.

Background: Cognitive impairment associated with schizophrenia (CIAS) negatively impacts daily functioning, quality of life, and recovery, yet effective pharmacotherapies and practical assessments for clinical practice are lacking. Despite the pivotal progress made with establishment of the Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) Consensus Cognitive Battery (MCCB) for clinical research, implementation of the full MCCB is too time-consuming and cost-ineffective for most clinicians in clinical practice.

Study Design: Here we discuss current assessments in relation to delivery format (interview-based and performance-based), validity, ease of use for clinicians and patients, reliability/reproducibility, cost-effectiveness, and suitability for clinical implementation.

Objective: To determine the impact of epidural spinal injections (ESIs) on postoperative surgical complications.

Methods: This retrospective all-payer database analysis identified 202,181 adult patients undergoing one- to three-level transforaminal lumbar interbody fusion (TLIF) from 2010 to 2020. A 1:1 exact matching on comorbidities and demographics was performed, creating 2 cohorts: 1) patients who received an ESI within 90 days of surgery and 2) patients who did not receive an ESI.

Engineering human midbrain organoid microphysiological systems to model prenatal PFOS exposure.

Perfluorooctane sulfonate (PFOS), a class of synthetic chemicals detected in various environmental compartments, has been associated with dysfunctions of the human central nervous system (CNS). However, the underlying neurotoxicology of PFOS exposure is largely understudied due to the lack of relevant human models. Here, we report bioengineered human midbrain organoid microphysiological systems (hMO-MPSs) to recapitulate the response of a fetal human brain to multiple concurrent PFOS exposure conditions.

The pervasive influence of systems of power on transition readiness for adult care in sickle cell disease: A qualitative study.

Background: Adolescence and young adulthood are vulnerable developmental periods for individuals with sickle cell disease (SCD), particularly given the impact of social inequities, challenges with transitioning to adult healthcare services, and increased risk for morbidity and mortality. Systems of power, such as institutionalized and interpersonal manifestations of bias, could impact SCD transfer and engagement in adult care through their influence on healthcare transition readiness; yet research in this area is limited.

Objective: To characterize how systems of power impact transition readiness factors described in the Social-ecological Model of AYA Readiness for Transition to Promote Health Equity (SMART-E) framework at the patient, caregiver, and practitioner levels.

Machine-learning-based integrative -'omics analyses reveal immunologic and metabolic dysregulation in environmental enteric dysfunction.

Environmental enteric dysfunction (EED) is a subclinical enteropathy challenging to diagnose due to an overlap of tissue features with other inflammatory enteropathies. EED subjects ( = 52) from Pakistan, controls ( = 25), and a validation EED cohort ( = 30) from Zambia were used to develop a machine-learning-based image analysis classification model. We extracted histologic feature representations from the Pakistan EED model and correlated them to transcriptomics and clinical biomarkers.

PECARN prediction rule for cervical spine imaging of children presenting to the emergency department with blunt trauma: a multicentre prospective observational study.

Background: Cervical spine injuries in children are uncommon but potentially devastating; however, indiscriminate neck imaging after trauma unnecessarily exposes children to ionising radiation. The aim of this study was to derive and validate a paediatric clinical prediction rule that can be incorporated into an algorithm to guide radiographic screening for cervical spine injury among children in the emergency department.

Methods: In this prospective observational cohort study, we screened children aged 0-17 years presenting with known or suspected blunt trauma at 18 specialised children's emergency departments in hospitals in the USA affiliated with the Pediatric Emergency Care Applied Research Network (PECARN).

Region-specific changes in brain glutamate and gamma-aminobutyric acid across the migraine attack in children and adolescents.

In patients with migraine, an excitation-inhibition imbalance that fluctuates relative to attack onset has been proposed to contribute to the underlying pathophysiology of migraine, but this has yet to be explored in children and adolescents. This prospective, observational, cohort study examined glutamate and gamma-aminobutyric acid (GABA) levels across the phases of a migraine attack and interictally in children and adolescents using magnetic resonance spectroscopy. Macromolecule-suppressed GABA (sensorimotor cortex and thalamus) and glutamate (occipital cortex, sensorimotor cortex, and thalamus) were measured in children and adolescents (10-17 years) with a migraine diagnosis with or without aura 4 times over 2 weeks.

BRG1 programs PRC2-complex repression and controls oligodendrocyte differentiation and remyelination.

Chromatin-remodeling protein BRG1/SMARCA4 is pivotal for establishing oligodendrocyte (OL) lineage identity. However, its functions for oligodendrocyte-precursor cell (OPC) differentiation within the postnatal brain and during remyelination remain elusive. Here, we demonstrate that Brg1 loss profoundly impairs OPC differentiation in the brain with a comparatively lesser effect in the spinal cord.
