Hypothesis: Viscous fingering instabilities of air displacing water displacing mineral oil is controlled by the air injection rate. Given the lower viscosity of the water, air would tend to finger through the water and then after it reaches the oil, proceed to finger through the oil.

Experiments: In a radial Hele-Shaw cell, experiments were conducted on air injection into mineral oil and air injection into a volume of water at the center of the cell which in turn is surrounded by mineral oil.

Probing Autism and ADHD subtypes using cortical signatures of the T1w/T2w-ratio and morphometry.

Neuroimage Clin

January 2025

The Mouse Imaging Centre, Hospital for Sick Children, Toronto, Ontario, Canada; Department of Medical Biophysics, Faculty of Medicine, University of Toronto, Toronto, Canada; Wellcome Centre for Integrative Neuroimaging, FMRIB, Nuffield Department of Clinical Neurosciences, University of Oxford, Oxford, United Kingdom.

Autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) are neurodevelopmental conditions that share genetic etiology and frequently co-occur. Given this comorbidity and well-established clinical heterogeneity, identifying individuals with similar brain signatures may be valuable for predicting clinical outcomes and tailoring treatment strategies. Cortical myelination is a prominent developmental process, and its disruption is a candidate mechanism for both disorders.

JAMA Pediatr

January 2025

Department of Pediatrics, Children's Hospital of Eastern Ontario, University of Ottawa, Ottawa, Ontario, Canada.

Importance: Detection of congenital cytomegalovirus (cCMV) infection has previously relied on targeted screening programs or clinical recognition; however, these approaches miss most cCMV-infected newborns and fail to identify those infants who are asymptomatic at birth but at risk for late-onset sensorineural hearing loss.

Objective: To determine the feasibility of using routinely collected newborn dried blood spots (DBS) in a population-based cCMV screen to identify infants at risk for hearing loss and describe outcomes of infants screened.

Design, Setting, And Participants: This diagnostic study of a population-based screening program in Ontario, Canada, took place from July 29, 2019, to July 31, 2023.

Introduction: Considering the impact of non-medical factors (personal and social) on patients with multiple chronic conditions, the term 'medical complexity' is gaining traction as it encompasses both medical and non-medical aspects of patients' medical needs. When primary care is not able to provide timely care for chronic challenges or acute concerns, complex patients require care in emergency or urgent care settings. The concept of medical complexity is continually evolving, although without a universally accepted or standardised definition that determines if an adult patient is considered complex.
