Article Synopsis
- The study investigates how somatic mitochondrial DNA mutations influence the development of leukemia, specifically through experiments with hematopoietic progenitor cells (HPCs) from genetically modified mice.
- Researchers found that recipients of heterozygous mtDNA mutator HPCs had a higher spontaneous leukemia incidence, while homozygous mtDNA mutator HPCs had a lower incidence when combined with NMyc overexpression.
- Both types of HPCs exhibited mitochondrial function impairments, but only heterozygous HPCs adapted to the metabolic demands of NMyc overexpression, as demonstrated by altered glucose utilization linked to metabolic changes in homozygous HPCs.
Purpose: To investigate the relationship between the distribution and severity of hypertonicity and spasticity on walking speed in people with neurological injuries.
Material/methods: This cross-sectional observation cohort study used the Modified Ashworth Scale (MAS) and Modified Tardieu Scale (MTS) to assess hypertonicity and spasticity of the gastrocnemius, soleus, hamstrings and quadriceps. Participants were classified as having a distal (gastrocnemius and/or soleus), proximal (hamstrings and/or quadriceps) or mixed distribution of hypertonicity or spasticity.
Background: Patients with heart failure (HF) can experience a poor quality-of-life (QOL), recurring hospitalizations, and progressive disease symptoms. Patient-reported outcome measures (PROMs) integrate patients' voices into clinical care, by assessing patient symptoms, function, and QOL. In 2022, PROMs were incorporated into the electronic health record system (Epic) at a large academic hospital in Toronto, Ontario, Canada.

From September 2022 to March 2023, the WAHA and University Health Network engaged in a partnership that designed a collaborative model of care to address inequities in cardiology specialist access in Northern Ontario. This model implemented a digital therapeutic for heart failure, (the Medly program) and in-person cardiology clinics in the region.

Methods: This single-centre, prospective proof-of-concept study described sociodemographic and medical characteristics of included patients, and computed summary statistics to describe clinical and workload outcomes.
