Background: Amyotrophic lateral sclerosis (ALS) is characterized by a rapid disease course, with disease severity being associated with declining health-related quality of life (HRQoL) in persons living with ALS (pALS). The main objective of this study was to assess the impact of disease progression on HRQoL across King's, Milano-Torino Staging (MiToS), and physician-judgement clinical staging. Additionally, we evaluated the impact of the disease on the HRQoL of care partners (cALS).

Background: Partnering with consumers in the planning, delivery and evaluation of health services is an essential component of person-centred care. There are many ways to partner with consumers to improve health services, including formal group partnerships (such as committees, boards or steering groups). However, consumers' and health providers' views and experiences of formal group partnerships remain unclear.

Classroom physical activity breaks (CAB) are beneficial for increasing children's physical activity (PA) levels as well as the amount of time spent being on-task within the classroom. To examine the effect of CAB at different times within the school day on on-task behavior and PA levels in primary school (grade 1-3) children. Thirty-five children (6 ± 1 y, 22 = male, 13 = female) participated in four conditions in a randomized order: morning (AM), afternoon (PM), morning and afternoon (BOTH), and no CAB (CTRL).

Handedness is a significant behavioral asymmetry; however, there is debate surrounding the age at which hand preference develops, and little research has been conducted on handedness in older adults. The current study examined performance on the long pegboard, to identify similarities and differences in young children (ages 4-7 years), older children (ages 8-12 years), young adults (ages 18-25 years), and older adults (ages 70+ years). Average time per hole, number of hand switches, and errors were assessed with left- and right-hand starts.

Background: Before the advent of automatism in image-making practices, scientists, anatomists, and physicians artistically depicted simplified images for scientific atlas making. This technique conferred subjectivity to a supposedly objective scientific process, sparking confrontations between anatomists regarding accuracy that heralded a new concept in the late 19 century - mechanical objectivity - that would revolutionize scientific knowledge and the field of medicine OBJECTIVES: The purpose of this health history research study is to trace the evolution of mechanical objectivity from empirical studies of early anatomists in the 19 century to the advent of x-ray technology, digitization of imaging, and disruptive technological innovations such as artificial intelligence, while simultaneously unveiling the challenges of mitigating human bias, despite advancements in medical imaging practices.

Methods: This narrative literature review was conducted using the Scopus® database under the guidance of both medical historians and practicing physicians to ensure its applicability and historical accuracy CONCLUSION: Despite a century-long quest for optimizing mechanical objectivity in diagnostic imaging to more accurately and efficiently interpret medical images, human bias remains an important factor.

COVID-19 restrictions have necessitated child/youth mental health providers to shift towards virtually delivering services to patients' homes rather than hospitals and community mental health clinics. There is scant guidance available for clinicians on how to address unique considerations for the virtual mental healthcare of children and youth as clinicians rapidly shift their practices away from in-person care in the context of the COVID-19 pandemic. Therefore, we bridge this gap by discussing a six-pillar framework developed at Hospital for Sick Children (SickKids) in Toronto, Ontario, Canada, for delivering direct to patient virtual mental healthcare to children, youth and their families.

A leading cause of physical injury sustained by elderly persons is the event of unintentionally falling. A delay between the time of fall and the time of medical attention can exacerbate injury if the fall resulted in a concussion, traumatic brain injury, or bone fracture. The authors present a solution capable of finding and tracking, in real-time, the location of an elderly person within an indoor facility, using only existing Wi-Fi infrastructure.

This article explores conceptual and methodological challenges surrounding the recovery of patients' voices in the history of medicine. We examine the debate that followed Roy Porter's seminal article, 'The Patient's View: Doing Medical History from Below' (1985). Porter argued that patients should be given a central role in medical history, aiming to restore to patients a voice and agency that is often lost in 'physician-centered' historical narratives.

Perceptual and visuomotor skills undergo considerable development from early childhood into adolescence; however, the concurrent maturation of these skills has not yet been examined. This study assessed visuomotor function and motion perception in a cross-section of 226 typically-developing children between 4 and 16 years of age. Participants were tested on three tasks hypothesized to engage the dorsal visual stream: threading a bead on a needle, marking dots using a pen, and discriminating form defined by motion contrast.

Determine the optimal, licensed, first-line anticoagulant for prevention of ischemic stroke in patients with non-valvular atrial fibrillation (AF) in England and Wales from the UK National Health Service (NHS) perspective and estimate value to decision making of further research. We developed a cost-effectiveness model to compare warfarin (international normalized ratio target range 2-3) with directly acting (or non-vitamin K antagonist) oral anticoagulants (DOACs) apixaban 5 mg, dabigatran 150 mg, edoxaban 60 mg, and rivaroxaban 20 mg, over 30 years post treatment initiation. In addition to death, the 17-state Markov model included the events stroke, bleed, myocardial infarction, and intracranial hemorrhage.

There is inconsistent evidence demonstrating a relationship between task complexity and hand preference. However, analyzing the point at which task complexity overrides the decision to demonstrate a biomechanically efficient movement can enable complexity to be quantified. Young children (ages 3-7), adolescents (ages 8-12), young adults (ages 18-25), and older adults (ages 65+) performed a newly developed Hand Selection Complexity Task (HSCT) and completed the Waterloo Handedness Questionnaire (WHQ).

Autism Spectrum Disorder (ASD) affects ~1 in 59 people in North America and diagnoses continue to rise (Center for Disease Control and Prevention, 2018). Unfortunately, the exact cause of ASD is unknown and therapy remains the primary means of intervention. People with ASD experience social and behavioral deficits associated with the disorder, which affect all aspects of life such as academics, relationships, and physical activity.

Introduction And Methods: Hand selection was assessed in preadolescent children (ages 9-11) within a preferential reaching task to delineate the effects of object location, orientation, and task intention on the assessment procedure and compared to data previously acquired from young adults.

Results: The observed differences support the notion that children are still in a process of refining their movements in attempt to discern the most efficient and effective patterns of behavior. Notwithstanding differences in performance, similarities between preadolescents and young adults also emerged.

Rationale: There are perennial calls for MD curricula to reform in order to meet the changing needs of students, patients, and society. And yet, efforts at renewal have also been suggested to have minimal impact on the pedagogy and outcomes of medical education. One reason may be misalignment between the components of the curriculum during design and implementation.

The movement context (pantomime, pantomime with image/object as guide, and actual use) has been shown to influence end-state comfort-the propensity to prioritize a comfortable final hand position over an initially comfortable one-across the lifespan. The present study aimed to assess how the movement context (pantomime, using a dowel as the tool, and actual use) influences end-state comfort when acting with objects (glass/hammer) that differ in use-dependent experience. Children (ages 6-11, n = 70), young adults (n = 21), and older adults (n = 21) picked up an overturned glass to pour water and a hammer to hit a nail, where the handle faced away from the participant.

There has been recent interest in the developmental trajectory of the end-state comfort effect (ESCE) in young children. However, potential sex differences have yet to be examined in the overturned glass task. We examined the ESCE using this task in a large sample (N=232) of typically-developing elementary school children (111 girls, 121 boys) in grades 1-5 (approximately 7-11years old).

Young adults plan actions in advance to minimize the cost of movement. This is exemplified by the end-state comfort (ESC) effect. A pattern of improvement in ESC in children is linked to the development of cognitive control processes, and decline in older adults is attributed to cognitive decline.
