Rethinking autism spectrum disorder assessment for children during COVID-19 and beyond.

Autism Res 2021 Sep 22. Epub 2021 Sep 22.

Department of Clinical Sciences, College of Medicine, Florida State University, Tallahassee, Florida, USA.

The COVID-19 pandemic has posed unique challenges for families and caregivers, as well as for autism-focused clinicians, who are faced with providing a thorough and accurate evaluation of children's specific needs and diagnoses in the absence of in-person assessment tools. The shift to telehealth assessments has challenged clinicians to reconsider approaches and assumptions that underlie the diagnostic assessment process, and to adopt new ways of individualizing standard assessments according to family and child needs. Mandates for physical distancing have uncovered deficiencies in diagnostic practices for suspected autism and have illuminated biases that have posed obstacles preventing children and families from receiving the services that they truly need.

The Safety of Agalsidase Alfa Enzyme Replacement Therapy in Canadian Patients with Fabry Disease Following Implementation of a Bioreactor Process.

Drugs R D 2021 Sep 20. Epub 2021 Sep 20.

Division of Nephrology, Department of Medicine, Dalhousie University, Rm 5090 ACC, QE II Health Sciences Centre, 5820 University Ave, Halifax, NS, B3H 1V8, Canada.

Background And Objective: Fabry disease, an X-linked lysosomal storage disorder characterized by absent or reduced alpha-galactosidase activity, is a lifelong disease that impairs patients' quality of life. Patients with Fabry disease have a considerably shortened lifespan, with mortality being mainly due to renal failure, cardiovascular disease, or cerebrovascular disease. Enzyme replacement therapy with agalsidase alfa has been shown to attenuate the renal, cardiovascular, and neuropathic disease progression associated with Fabry disease. Read More

Impact of a cancer diagnosis on the income of adult cancer survivors: a scoping review protocol.

BMJ Open 2021 Sep 16;11(9):e047315. Epub 2021 Sep 16.

Cancer Control Research, BC Cancer, Vancouver, British Columbia, Canada.

Introduction: While the socioeconomic impact of a cancer diagnosis on cancer survivors has gained some attention in the literature, to our knowledge, a review of the evidence on changes in income due to cancer has yet to be undertaken. In this paper, we describe a scoping review protocol to review the evidence on the effect of a cancer diagnosis on the income of individuals diagnosed with cancer during adulthood (≥18 years).

Deciphering the low abundance microbiota of presumed aseptic hip and knee implants.

PLoS One 2021 14;16(9):e0257471. Epub 2021 Sep 14.

Department of Surgery, Schulich School of Medicine & Dentistry, Western University, London, Ontario, Canada.

16S rRNA gene sequencing of DNA extracted from clinically uninfected hip and knee implant samples has revealed polymicrobial populations. However, previous studies assessed 16S rRNA gene sequencing as a technique for the diagnosis of periprosthetic joint infections, leaving the microbiota of presumed aseptic hip and knee implants largely unstudied. These communities of microorganisms might play important roles in aspects of host health, such as aseptic loosening. Read More

Front Genet 2021 27;12:737433. Epub 2021 Aug 27.

Department of Chemistry and Biochemistry, University of Lethbridge, Lethbridge, AB, Canada.

Translational control (TC) is one the crucial steps that dictate gene expression and alter the outcome of physiological process like programmed cell death, metabolism, and proliferation in a eukaryotic cell. TC occurs mainly at the translation initiation stage. The initiation factor eIF5B tightly regulates global translation initiation and facilitates the expression of a subset of proteins involved in proliferation, inhibition of apoptosis, and immunosuppression under stress conditions.

Bone Rep 2021 Dec 25;15:101121. Epub 2021 Aug 25.

Medical Genetics Division, Department of Pediatrics, CHU Sainte-Justine, Montreal, QC H3T 1C5, Canada.

Calvarial Doughnut Lesions with Bone Fragility (CDL) is an autosomal dominant genetic disease, characterized by low bone mineral density, multiple fractures starting in childhood, and sclerotic doughnut-shaped lesions in the cranial bones. Aubé and colleagues described in 1988 a French-Canadian family of 12 affected members who had a clinical diagnosis of doughnut lesions of the skull, with pathological fractures, osteopenia, "bone in bone" in the vertebral bodies and squaring of metatarsal and metacarpal bones. Herein we study new members of this family. Read More

Molecular Diagnosis of Pompe Disease in the Genomic Era: Correlation with Acid Alpha-Glucosidase Activity in Dried Blood Spots.

J Clin Med 2021 Aug 28;10(17). Epub 2021 Aug 28.

Department of Pediatrics, Université de Sherbrooke, Sherbrooke, QC J1H 5H3, Canada.

Measurement of alpha-glucosidase activity on dried blood spots has been the main method to screen for Pompe disease, but a paradigm shift has been observed in recent years with the incorporation of gene panels and exome sequencing in molecular diagnostic laboratories. An 89-gene panel has been available to Canadian physicians since 2017 and was analyzed in 2030 patients with a suspected muscle disease. Acid alpha-glucosidase activity was measured in parallel in dried blood spots from 1430 patients. Read More

CARDEA study protocol: investigating early markers of cardiovascular disease and their association with lifestyle habits, inflammation and oxidative stress in adolescence using a cross-sectional comparison of adolescents with type 1 diabetes and healthy controls.

BMJ Open 2021 09 8;11(9):e046585. Epub 2021 Sep 8.

Department of Pediatrics, Université de Montréal, Montréal, Québec, Canada.

Introduction: Little is known regarding associations between potentially modifiable lifestyle habits and early markers of cardiovascular disease (CVD) in pediatric type 1 diabetes (T1D), hindering early prevention efforts. Specific objectives are: (1) compare established risk factors (dyslipidemia, hypertension) with novel early markers for CVD (cardiac phenotype, aortic distensibility, endothelial function) in adolescents with T1D and healthy age-matched and sex-matched controls; (2) examine associations between these novel early markers with: (i) lifestyle habits; (ii) adipokines and measures of inflammation; and (iii) markers of oxidative stress among adolescents with T1D and controls, and determine group differences in these associations; (3) explore, across both groups, associations between CVD markers and residential neighbourhood features.

Methods And Analyses: Using a cross-sectional design, we will compare 100 participants aged 14-18 years with T1D to 100 healthy controls. Read More

Characterising fetal alcohol spectrum disorder in Canada: a national database protocol study.

BMJ Open 2021 09 6;11(9):e046071. Epub 2021 Sep 6.

The Canada FASD Research Network, Edmonton, Alberta, Canada.

Introduction: Fetal alcohol spectrum disorder (FASD) is one of the most common neurodevelopmental disorders in North America. It is a complex disability, associated with challenges in cognitive, behavioural and socialemotional functioning, as well as an increased risk of physical and mental health comorbidities, and difficulties in daily living across the lifespan. Previous attempts to characterise the profile of this population have been hampered by differences in data collected across studies, regional discrepancies in terminology and definitions, and a lack of tools to integrate comprehensive datasets.
