Sleep Disturbance and Postconcussive Symptoms in Pediatric Mild Traumatic Brain Injury and Orthopedic Injury.

Objective: Sleep disturbance (SD) is common after pediatric mild traumatic brain injury (mTBI) and may predict increased postconcussive symptoms (PCS) and prolonged recovery. Our objective was to investigate the relation of SD with PCS in children with mTBI and those with orthopedic injury (OI).

Setting: Emergency departments (EDs) at 2 children's hospitals in the Midwestern United States.

Aura phenomenon: a proposal for an etiology-based clinical classification.

Background: The term "aura" refers to a well-defined pattern of usually positive, progressive, and reversible neurological symptoms, with spreading depolarization as the underlying mechanism. While commonly associated with migraine, aura can also occur in other neurological disorders (i.e.

Antiseizure Medications and Cardiovascular Events in Older People With Epilepsy in the Canadian Longitudinal Study on Aging.

Importance: How epilepsy may promote cardiovascular disease remains poorly understood.

Objective: To estimate the odds of new-onset cardiovascular events (CVEs) over 6 years in older people with vs without epilepsy, exploring how enzyme-inducing antiseizure medications (EIASMs) and traditional cardiovascular risk factors mediate these odds.

Design, Setting, And Participants: This was a prospective cohort study using the comprehensive cohort of the Canadian Longitudinal Study on Aging (CLSA), with 6 years of follow-up (2015-2021, analysis performed in December 2023).

Impact of age-related changes in buccal epithelial cells on pediatric epigenetic biomarker research.

Cheek swabs, heterogeneous samples consisting primarily of buccal epithelial cells, are widely used in pediatric DNA methylation studies and biomarker creation. However, the decrease in buccal proportion with age in adults remains unexamined in childhood. We analyzed cheek swabs from 4626 typically developing children 2-months to 20-years-old.

Care for older adults living with dementia in the emergency department: a systematic review and meta-synthesis of care partner roles and perspectives.

Objective: Care partners play a vital role in supporting persons living with dementia (PLWD) in using medical services. We conducted a meta-synthesis to explore care partner perspectives of ED care for PLWD, as well as healthcare provider (HCP) perceptions of care partner roles within the ED, to identify care gaps and facilitators across the ED continuum.

Methods: MEDLINE, PsycINFO and Embase databases were searched from inception to 8 May 2023.

Acute and chronic cannabis vapor exposure influences basal and stress-induced release of glucocorticoids in male and female rats.

Management of stress and anxiety is often listed as the primary motivation behind cannabis use. Human research has found that chronic cannabis use is associated with increased basal cortisol levels but blunted neuroendocrine responses to stress. Preclinical research has demonstrated mixed effects of Δ-tetrahydrocannabinol (THC; the psychoactive constituent of cannabis), much of which is suggestive of dose-dependent effects; however, the predominance of this work has employed an injection method to deliver cannabis.

Knockout of the ING5 epigenetic regulator confirms roles in stem cell maintenance and tumor suppression in vivo.

INhibitor of Growth (ING1-5) proteins are epigenetic readers that target histone acetyltransferase (HAT) or histone deacetylase (HDAC) complexes to the H3K4Me3 mark of active transcription. ING5 targets Moz/Morf and HBO1 HAT complexes that alter acetylation of H3 and H4 core histones, affecting gene expression. Previous experiments in vitro indicated that ING5 functions to maintain stem cell character in normal and in cancer stem cells.

The effect of nature on creativity through mental imagery.

Immersion in nature has been linked to wide-ranging benefits on mental health and cognitive functions, from reducing stress to enhancing creativity. However, a walk in nature is not always feasible, and whether a proxy for nature immersion via a mental walk in nature can elicit the same benefits as a physical walk remains largely unknown. Accordingly, the current study utilized guided imagery to examine whether a mental walk in nature would improve creativity in general and when compared to a mental walk in an urban environment.

Ghrelin recruits the endocannabinoid system to modulate food reward.

Ghrelin enhances feeding by activating the growth hormone secretagogue receptor (GHSR). In the brain, GHSRs are expressed in regions responsible for regulating food motivation including the ventral tegmental area (VTA). Endogenous cannabinoids also promote food seeking behaviors through the cannabinoid receptor 1 type (CB-1Rs) in brain regions including the VTA.

Evaluating a 12-week aerobic exercise intervention in adults with persisting post-concussive symptoms.

Background: Although guidelines support aerobic exercise in sub-acute mild traumatic brain injury (mTBI), evidence for adults with persisting post-concussive symptoms (PPCS) after mTBI is lacking. The objective was to evaluate the impact of a sub-symptom threshold aerobic exercise intervention on overall symptom burden and quality of life in adults with PPCS.

Methods: This prospective cohort study was nested within the ACTBI Trial (Aerobic Exercise for treatment of Chronic symptoms following mild Traumatic Brain Injury).

Considering the impact of vaccine communication in the COVID-19 pandemic among adults in Canada: A qualitative study of lessons learned for future vaccine campaigns.

We aimed to understand how experiences with vaccine-related information and communication challenges during the COVID-19 pandemic impacted motivations and behaviors among Canadian adults regarding future vaccines. Semi-structured interviews were conducted with participants purposively selected to ensure diversity in age, sex at birth, self-identified gender, and region. Data were analyzed using thematic analysis; findings were mapped to the Information-Motivation-Behavioral Skills Model focusing on factors affecting vaccine hesitancy and uptake.

Recombinant Human Tissue Kallikrein-1 for Treating Acute Ischemic Stroke and Preventing Recurrence.

Novel strategies are needed for the treatment of acute ischemic stroke when revascularization therapies are not clinically appropriate or are unsuccessful. rKLK1 (recombinant human tissue kallikrein-1), a bradykinin-producing enzyme, offers a promising potential solution. In animal studies of acute stroke, there is a marked 36-fold increase in bradykinin B2 receptor on brain endothelial cells of the ischemic region.

Therapeutic reduction of neurocan in murine intracerebral hemorrhage lesions promotes oligodendrogenesis and functional recovery.

Background: Intracerebral hemorrhage (ICH) causes prominent deposition of extracellular matrix molecules, particularly the chondroitin sulphate proteoglycan (CSPG) member neurocan. In tissue culture, neurocan impedes the properties of oligodendrocytes. Whether therapeutic reduction of neurocan promotes oligodendrogenesis and functional recovery in ICH is unknown.

Cognitive, behavioral, and functional outcomes of suspected mild traumatic brain injury in community-dwelling older persons without mild cognitive impairment or dementia.

Introduction: Traumatic brain injury (TBI) is associated with greater risk and earlier onset of dementia. This study investigated whether later-life changes in subjective cognition and behavior - potential markers of AD - could be observed in cognitively unimpaired older persons with a history of suspected mild TBI (smTBI) earlier in life and whether changes in cognition and behavior mediated the link between smTBI and daily function.

Methods: Data for 1392 participants from the Canadian Platform for Research Online to Investigate Health, Quality of Life, Cognition, Behaviour, Function, and Caregiving in Aging (CAN-PROTECT) were analyzed.

- a large-scale dataset of 3D medical shapes for computer vision.

Objectives: The shape is commonly used to describe the objects. State-of-the-art algorithms in medical imaging are predominantly diverging from computer vision, where voxel grids, meshes, point clouds, and implicit surface models are used. This is seen from the growing popularity of ShapeNet (51,300 models) and Princeton ModelNet (127,915 models).

A systematic review of the comparative effects of sound and music interventions for intensive care unit patients' outcomes.

Background: Despite syntheses of evidence showing efficacy of music intervention for improving psychological and physiological outcomes in critically ill patients, interventions that include nonmusic sounds have not been addressed in reviews of evidence. It is unclear if nonmusic sounds in the intensive care unit (ICU) can confer benefits similar to those of music.

Objective: The aim of this study was to summarise and contrast available evidence on the effect of music and nonmusic sound interventions for the physiological and psychological outcomes of ICU patients based on the results of randomised controlled trials.

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.

Exposure to Perinatal Trauma Modifies Nociception and Gene Expression in the Prefrontal Cortex and Hypothalamus of Adolescent Rats.

The perinatal period encompasses a critical window for neurodevelopment that renders the brain highly responsive to experience. Trauma, such as intimate partner violence (IPV) and early life stress/neglect, during this period negatively affects physical and mental health outcomes, including increasing ones risk for chronic pain. Although epigenetic programming likely contributes, the mechanisms that drive the relationship between perinatal trauma and adverse health outcomes, are not fully understood.
