The incidence of and risk factors for axillary web syndrome with limited shoulder movement after surgery for breast cancer, and the effect of early physical therapy intervention.

Background: The aims of this cohort study were to identify (1) the incidence and risk factors for axillary web syndrome (AWS) with shoulder movement limitation within 4 weeks after axillary lymph node dissection (ALND) for Asian women with breast cancer (BC), and (2) whether early intervention with physical therapy (PT) could improve AWS, and how many PT sessions would be needed.

Methods: A cohort study of patients with BC receiving ALND was performed at Changhua Christian Hospital, Taiwan, between January 2019 and December 2020. Those patients who were diagnosed with AWS with shoulder movement limitation were referred to receive PT twice weekly at the Department of Physical Medicine and Rehabilitation.

Sweat chloride reflects CFTR function and correlates with clinical outcomes following CFTR modulator treatment.

Background: Highly effective CFTR modulators improve CFTR function and lead to dramatic improvements in health outcomes in many people with cystic fibrosis (pwCF). The relationship between measures of CFTR function, such as sweat chloride concentration, and clinical outcomes in pwCF treated with CFTR modulators is poorly defined. We conducted analyses to better understand the relationships between sweat chloride and CFTR function in vitro, and between sweat chloride and clinical outcomes following CFTR modulator treatment.

Built environment change for injury prevention: insights from public health professionals across public health units in Ontario, Canada.

Background: Road-related injuries and deaths are among the most significant and avoidable public health problems in Canada. Modifications to the built environment (BE) can reduce injury rates for vulnerable road users (VRUs) and other priority populations who experience disproportionate risk. This paper highlights public health professionals' experiences working in injury prevention across Ontario public health units (PHUs) navigating barriers and facilitators to BE change.

Exploring adolescents' experiences navigating the intersection of their gender, sport, and dietary identities: an interpretative phenomenological study.

Not all adolescents have positive sport experiences. Research has repeatedly identified ties between unfavorable eating patterns and food beliefs (i.e.

The use of patient-generated health data in the management of low anterior resection syndrome: a qualitative study.

Background: The cornerstone of low anterior resection syndrome (LARS) treatment is self-management, which requires patient engagement. Colorectal surgeons and nurses may use patient-generated health data (PGHD) to help guide patients in their use of self-management strategies for LARS. However, the perspectives of LARS experts on the use of PGHD remain largely unexplored.

Low-density scalp electrical source imaging of the ictal onset zone network using source coherence maps.

Introduction: This study investigated low-density scalp electrical source imaging of the ictal onset zone and interictal spike ripple high-frequency oscillation networks using source coherence maps in the pediatric epilepsy surgical workup. Intracranial monitoring, the gold standard for determining epileptogenic zones, has limited spatial sampling. Source coherence analysis presents a promising new non-invasive technique.

Towards a critical posthumanist perspective on participatory design.

Participatory design places a strong emphasis on human agency, user perspectives and democratic ideals of inclusivity and empowerment, and is therefore often associated with humanist principles and values. In contrast, critical posthumanism questions key humanist assumptions about the centred and singular nature of the 'human condition'. Instead, posthumanism points to the evolving and diverse lived experiences of people and how these are transformed by (and are transforming of) culture, environment and technology.

Contralateral oculomotor nerve palsy associated with PHACES syndrome.

A 13-month-old boy presented to the pediatric ophthalmology clinic at BC Children's Hospital for strabismus assessment. On examination he had a right facial hemangioma, left ptosis, and left exotropia and hypotropia. Magnetic resonance imaging and magnetic resonance angiography of his head demonstrated posterior cerebral artery tortuosity producing mild mass effect on the left oculomotor nerve.

The fungal gut microbiota in pediatric-onset multiple sclerosis.

Evidence suggests that the gut microbiome may play a role in multiple sclerosis (MS). However, the majority of the studies have focused on gut bacterial communities; none have examined the fungal microbiota (mycobiota) in persons with pediatric-onset multiple sclerosis (POMS). We examined the gut mycobiota in persons with and without POMS through a cross-sectional examination of the gut mycobiota from 46 participants' stool samples (three groups: 18 POMS, 13 acquired monophasic demyelinating syndromes [monoADS], and 15 unaffected controls).

An assessment of cord ferritin concentration and its predictors among a cohort of Canadian preterm and term infants.

Low iron stores at birth may adversely influence child cognitive and motor development. The aims of this study were to assess cord blood iron levels and explore maternal and neonatal factors associated with iron status. Cord blood specimens (=46) were obtained from the BC Children's Hospital BioBank in Vancouver, Canada.

HELP-KIDNEY: Health Literacy and Patient Outcomes in Pediatric Kidney Transplant.

Background: Below adequate health literacy is common and linked to increased risk of adverse health outcomes. Supporting optimal health following kidney transplantation requires the capacity to understand health information and make decisions about care. The impact of low health literacy in the context of pediatric kidney transplant has not previously been studied.

Outcomes Using a Standardized Provincial Childhood Nephrotic Syndrome Clinical Pathway.

Background: In 2013, the British Columbia (BC) Childhood Nephrotic Syndrome Clinical Pathway (CNSCP) was developed to standardize the care of children with nephrotic syndrome (NS). In BC, children access nephrology care at BC Children's Hospital (BCCH) and multiple regional clinics.

Objective: The primary objective was to compare induction therapy and clinical outcomes between BCCH and regional clinics since implementation of the CNSCP.

Case report: Canadian consensus on chlormethine gel use in mycosis fungoides-CTCL: literature review and real-world experience.

Mycosis fungoides (MF) is the most common type of cutaneous T-cell lymphoma (CTCL), representing the majority of all lymphomas arising in the skin. The disease treatment focuses on managing symptoms and preventing disease evolution. To date, there is no gold standard for MF-CTCL treatment.

vmrseq: probabilistic modeling of single-cell methylation heterogeneity.

Single-cell DNA methylation measurements reveal genome-scale inter-cellular epigenetic heterogeneity, but extreme sparsity and noise challenges rigorous analysis. Previous methods to detect variably methylated regions (VMRs) have relied on predefined regions or sliding windows and report regions insensitive to heterogeneity level present in input. We present vmrseq, a statistical method that overcomes these challenges to detect VMRs with increased accuracy in synthetic benchmarks and improved feature selection in case studies.

Polygenic score distribution differences across European ancestry populations: implications for breast cancer risk prediction.

Background: The 313-variant polygenic risk score (PRS) provides a promising tool for clinical breast cancer risk prediction. However, evaluation of the PRS across different European populations which could influence risk estimation has not been performed.

Methods: We explored the distribution of PRS across European populations using genotype data from 94,072 females without breast cancer diagnosis, of European-ancestry from 21 countries participating in the Breast Cancer Association Consortium (BCAC) and 223,316 females without breast cancer diagnosis from the UK Biobank.

- 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).

The role of C-reactive protein and ferritin in the diagnosis of HLH, adult-onset still's disease, and COVID-19 cytokine storm.

Cytokine storm syndromes such as hemophagocytic lymphohistiocytosis (HLH), Adult-onset Still's disease (AOSD), and COVID-19 cytokine storm (CCS) are characterized by markedly elevated inflammatory cytokines. However clinical measurement of serum cytokines is not widely available. This study examined the clinical utility of C-reactive protein (CRP) and ferritin, two inexpensive and widely available inflammatory markers, for distinguishing HLH from AOSD and CCS.

Towards a histological diagnosis of childhood small vessel CNS vasculitis.

Background: Primary small vessel CNS vasculitis (sv-cPACNS) is a challenging inflammatory brain disease in children. Brain biopsy is mandatory to confirm the diagnosis. This study aims to develop and validate a histological scoring tool for diagnosing small vessel CNS vasculitis.

Modified Crohn's Disease Exclusion Diet Maintains Remission in Pediatric Crohn's Disease; Randomized Controlled Trial.

Background & Aims: The Crohn's Disease (CD) Exclusion Diet (CDED)+Partial Enteral Nutrition (PEN) is effective for inducing remission in mild-moderate CD. We assessed whether a 2-week course of Exclusive Enteral Nutrition (EEN), followed by CDED+PEN is superior to 8 weeks of EEN in sustaining clinical remission at week 14 in mild-to-severe CD and if CDED+PEN can maintain remission to week 24.

Methods: This international, multicenter, randomized-controlled trial compared 2-weeks of EEN (Modulen®IBD) followed by 3 phases of the CDED+PEN (henceforth CDED) to 8 weeks of EEN, followed by PEN with free diet up to week 24 (henceforth EEN).

Family Genetic Risk Communication and Reverse Cascade Testing in the BabySeq Project.

Purpose: Genomic sequencing of newborns (NBSeq) can initiate disease surveillance and therapy for children, and may identify at-risk relatives through reverse cascade testing. We explored genetic risk communication and reverse cascade testing among families of newborns who underwent exome sequencing and had a risk for autosomal dominant disease identified.

Methods: We conducted semi-structured interviews with parents of newborns enrolled in the BabySeq Project who had a pathogenic or likely-pathogenic (P/LP) variant associated with an autosomal dominant (AD) childhood- and/or adult-onset disease returned.

Assessing the impact of the iPeer2Peer program for adolescents with juvenile idiopathic arthritis: a mixed-methods randomized controlled trial.

Background: Juvenile Idiopathic Arthritis (JIA) is a chronic pediatric illness, whereby youth experience physical, emotional and psychosocial challenges that result in reduced health related quality of life (HRQL). Peer mentoring has been shown to improve disease self-management in adults with chronic conditions, with mixed results in younger populations. Building on our pilot work - which supported the feasibility and initial effectiveness of the iPeer2Peer program - the objective of this study was to assess the clinical effectiveness of the program in youth with JIA through a waitlist randomized controlled trial.

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.

Prognostic and predictive implications of sterile alpha motif and HD domain-containing protein 1 (SAMHD1) expression in breast cancer.

Sterile alpha motif and HD domain-containing protein 1 (SAMHD1) is a dNTP hydrolase important for intracellular dNTP homeostasis and serves as tumor suppressor and modulator of antimetabolite efficacy in cancer, though largely unexplored in breast cancer (BC). A cohort of patients with early BC (n = 564) with available gene expression data (GEP) was used. SAMHD1 protein expression was assessed by immunohistochemistry performed on tissue microarrays.

CD4 T Cells Mediate Dendritic Cell Licensing to Promote Multi-Antigen Anti-Leukemic Immune Response.

Background: Single antigen (Ag)-targeted immunotherapies for acute lymphoblastic leukemia (ALL) are highly effective; however, up to 50% of patients relapse after these treatments. Most of these relapses lack target Ag expression, suggesting targeting multiple Ags would be advantageous.

Materials & Methods: The multi-Ag immune responses to ALL induced by transducing cell lines with xenoAgs green fluorescent protein and firefly luciferase was elucidated using flow cytometry, ELISA, and ELISpot assays.
