Evaluating the impact of modeling choices on the performance of integrated genetic and clinical models.

Purpose: The value of genetic information for improving the performance of clinical risk prediction models has yielded variable conclusions. Many methodological decisions have the potential to contribute to differential results. We performed multiple modeling experiments integrating clinical and demographic data from electronic health records (EHR) with genetic data to understand which decisions may affect performance.

Concordance and test-retest consistency of sleep biomarker-based neurodegenerative disorder profiling.

Biomarkers that aid in early detection of neurodegeneration are needed to enable early symptomatic treatment and enable identification of people who may benefit from neuroprotective interventions. Increasing evidence suggests that sleep biomarkers may be useful, given the bi-directional relationship between sleep and neurodegeneration and the prominence of sleep disturbances and altered sleep architectural characteristics in several neurodegenerative disorders. This study aimed to demonstrate that sleep can accurately characterize specific neurodegenerative disorders (NDD).

The role of navigation services in supporting mental health and addictions care transitions: A qualitative exploration of perspectives from transitional-aged youth, family, and service providers (part 2).

Introduction: Transitional-aged youth (TAY) are at a vulnerable stage of their development in which mental health and/or addiction (MHA) issues tend to manifest and/or increase in severity. These youth also tend to find themselves caught in the gap between child and adult MHA services, often resulting in sub-optimal access to and transition through MHA services. Navigation services may be one way to close this and other system gaps and improve service utilization and supports for TAY.

Experiences of barriers and facilitators in mental health care transitions: A qualitative exploration of perspectives from transitional-aged youth, family, and service providers (part 1).

Introduction: Transitional-aged youth (TAY) are at a vulnerable stage of their development in which mental health and/or addiction (MHA) issues tend to manifest and/or increase in severity. TAY also tend to find themselves subject to multiple care transitions, often resulting in sub-optimal access to MHA services. The objective of this study was to explore the perspectives of TAY, family members, and system providers regarding the supports needed by TAY and their families during transitions through MHA care.

The use of sequential multiple assignment randomized trials (SMARTs) in physical activity interventions: a systematic review.

Background: Physical activity (PA) is often the cornerstone in risk-reduction interventions for the prevention and treatment of many chronic health conditions. PA interventions are inherently multi-dimensional and complex in nature. Thus, study designs used in the evaluation of PA interventions must be adaptive to intervention components and individual capacities.
