Identifying 'Where' and 'How' Peer Support for Youth is Integrated into Community-Based Mental Health Services: A Survey Study.

To mitigate barriers to care among youth (12-25 years), community-based organizations have increasingly integrated peer support as a complement to clinical mental health care; however, information regarding the integration process is lacking. To explore organizational perspectives regarding the contexts and mechanisms underlying integration of peer support for youth accessing mental health services from community-based, youth-serving organizations. Representatives from community-based youth-serving organizations completed a survey describing the contexts in which they are located and their experiences integrating peer support.

Initially reliant on case reports and small case series, we now benefit from multicenter studies and randomized trials that can provide robust practice-changing evidencea and often employ sophisticated statistical methods. This two-part series on statistical principles in neurointervention aims to equip neurointerventionalists with essential statistical knowledge for critically reviewing literature and conducting methodologically sound research.

Detecting somatic variants in purified brain DNA obtained from surgically implanted depth electrodes in epilepsy.

Objective: Somatic variants causing epilepsy are challenging to detect, as they are only present in a subset of brain cells (e.g., mosaic), resulting in low variant allele frequencies.

Single-cell RNA sequencing identifies CXADR as a fate determinant of the placental exchange surface.

The placenta is the critical interface between mother and fetus, and consequently, placental dysfunction underlies many pregnancy complications. Placental formation requires an adequate expansion of trophoblast stem and progenitor cells followed by finely tuned lineage specification events. Here, using single-cell RNA sequencing of mouse trophoblast stem cells during the earliest phases of differentiation, we identify gatekeepers of the stem cell state, notably Nicol1, and uncover unsuspected trajectories of cell lineage diversification as well as regulators of lineage entry points.

Exome Sequencing in the Diagnostic Pathway for Suspected Rare Genetic Diseases: Does the Order of Testing Affect its Cost-Effectiveness?

Background: Patients with suspected rare diseases often experience lengthy and uncertain diagnostic pathways. This study aimed to estimate the cost-effectiveness of exome sequencing (ES) in different positions in the diagnostic pathway for patients suspected of having a rare genetic disease.

Methods: Data collected retrospectively from 305 patients suspected of having a rare genetic disease (RGD), who received clinical-grade ES and participated in the Canadian multicentre Care4Rare-SOLVE study, informed a discrete event simulation of the diagnostic pathway.

Ca signaling in vascular smooth muscle and endothelial cells in blood vessel remodeling: a review.

Vascular smooth muscle cells (VSMCs) and endothelial cells (ECs) act together to regulate blood pressure and systemic blood flow by appropriately adjusting blood vessel diameter in response to biochemical or biomechanical stimuli. Ion channels that are expressed in these cells regulate membrane potential and cytosolic Ca concentration ([Ca]) in response to such stimuli. The subsets of these ion channels involved in Ca signaling often form molecular complexes with intracellular molecules via scaffolding proteins.

Examining the link between parental relationship functioning and parent sensitivity: a meta-analysis.

Background: Fathers remain neglected in attachment research, despite paternal sensitivity being important for children's development. Past research suggested that fathers' parenting may be influenced by contextual factors, including relationship functioning between parents.

Objective: This meta-analysis examined the association between paternal sensitivity and parental relationship functioning, and compared the magnitude of associations to those of maternal sensitivity.

Application of a localized morphometrics approach to imaging-derived brain phenotypes for genotype-phenotype associations in pediatric mental health and neurodevelopmental disorders.

Introduction: Quantitative global or regional brain imaging measurements, known as imaging-specific or -derived phenotypes (IDPs), are commonly used in genotype-phenotype association studies to explore the genomic architecture of the brain and how it may be affected by neurological diseases (e.g., Alzheimer's disease), mental health (e.

Duration, course and caregiver burden of croup in children: two observational cohorts.

Objectives: Although croup is a common respiratory illness, there is little published regarding symptom course. We aimed to assess symptom progression and caregiver burden, and whether age, sex or season and initial severity of disease are associated with symptom duration.

Design, Setting And Participants: We conducted a secondary analysis of two Canadian prospective cohorts of children 0-16 years old diagnosed with croup; one recruited from a paediatric emergency department (ED) (307 children) between November 1999 and March 2000, and the other from 26 general EDs (1214 children) between September 2002 and April 2006.

Where are all the Services: Mapping Community-Based Services for Canadian Autistic Youth with Co-occurring Mental Health Conditions.

Purpose: Autistic youth are at heightened risk of mental health issues and face several barriers to accessing appropriate supports. A lack of available services is a common barrier that many autistic youth experience, with only 43% of autistic youth from the US who needed mental health services receiving them. Little is known about the availability of these mental health services in Canada, despite the high prevalence of mental health issues in autistic youth.

Downstream branches of receptor tyrosine kinase signaling act interdependently to shape the face.

Background –: Previously we found that increasing fibroblast growth factor (FGF) signaling in the neural crest cells within the frontonasal process (FNP) of the chicken embryo caused dysmorphology that was correlated with reduced proliferation, disrupted cellular orientation, and lower MAPK activation but no change in PLCy and PI3K activation. This suggests RTK signaling may drive craniofacial morphogenesis through specific downstream effectors that affect cellular activities. In this study we inhibited three downstream branches of RTK signaling to determine their role in regulating cellular activities and how these changes affect morphogenesis of the FNP.

What skills do adolescents and young adults desire as they prepare for adult health care?

Background: The transition from pediatric to adult care is a period associated with adverse health outcomes (e.g., health care dropout, health deterioration and poor adherence to management) for adolescents and young adults (AYA) with chronic conditions and their caregivers.

Amplifying adolescent and emerging adult voices: Development of a pediatric-to-adult transition research advisory council.

Background: Adolescents and emerging adults (AEA) with chronic health conditions may face numerous challenges when undergoing the transition from pediatric to adult health care. Despite the need for engagement with AEA in health research, little is known about how researchers operationalize this engagement. In an effort to enhance transparency in the practices of patient engagement, this commentary details the process of developing a pediatric-adult transition-specific youth advisory council in Alberta: the Transition Research Advisory Council (TRAC).

Transition experiences of adolescents and young adults working with a patient navigator.

Introduction: The transition from pediatric to adult care poses challenges for adolescents and young adults (AYA) with chronic conditions and their caregivers. A patient navigator (PN) intervention may mitigate transition-related barriers.

Methods: A qualitative study was conducted within a pragmatic randomized controlled trial.

Motivators and barriers to neurodevelopmental research enrolment.

Participant recruitment for studies investigating neurodevelopmental conditions can be difficult, limited, and resource intensive. In this study, caregivers were surveyed to learn about the factors influencing their decision to enroll their neurodivergent child in research. Data were collected through an online survey from caregivers of neurodivergent children who were signing up for a research recruitment database (n = 46).

Developmental Mismatch Across Brain Modalities in Young Children.

Brain development during the preschool period is complex and extensive and underlies ongoing behavioral and cognitive maturation. Increasing understanding of typical brain maturation during this time is critical to early identification of atypical development and could inform treatments and interventions. Previous studies have suggested mismatches between brain structural and functional development in later childhood and adolescence.

Tracking of spaceflight-induced bone remodeling reveals a limited time frame for recovery of resorption sites in humans.

Mechanical unloading causes bone loss, but it remains unclear whether disuse-induced changes to bone microstructure are permanent or can be recovered upon reloading. We examined bone loss and recovery in 17 astronauts using time-lapsed high-resolution peripheral quantitative computed tomography and biochemical markers to determine whether disuse-induced changes are permanent. During 6 months in microgravity, resorption was threefold higher than formation.

Turbulence in the system: Higher rates of left-without-being-seen emergency department visits and associations with increased risks of adverse patient outcomes since 2020.

Objective: To examine risks of severe adverse patient outcomes shortly after a left-without-being-seen emergency department (LWBS ED) visit since 2020.

Methods: In this retrospective study using linked administrative data, we examined temporal trends in monthly rates of ED and LWBS visits for adults in Ontario, Canada, 2014‒2023. In patient-level analyses restricted to the first eligible LWBS ED visit, we used modified Poisson regression to compare the composite outcome of 7-day all-cause mortality or hospitalization following a LWBS ED visit for April 1, 2022‒March 31, 2023 (recent period) to April 1, 2014‒March 31, 2020 (baseline period), adjusted for age, sex, and Charlson comorbidity index.
