Prosthetic Limb Attachment via Electromagnetic Attraction Through a Closed Skin Envelope.

Objective: Current socket-based methods of prosthetic limb attachment are responsible for many of the dominant problems reported by persons with amputation. In this work, we introduce a new paradigm for attachment via electromagnetic attraction between a bone-anchored ferromagnetic implant and an external electromagnet. Our objective was to develop a design framework for electromagnetic attachment, and to evaluate this framework in the context of transfemoral amputation.

Advancing Family Presence Policies and Practices in the Canadian Health and Care Context: COVID-19 and Beyond.

With the onset of the COVID-19 pandemic, restrictive visitor policies have curtailed the ability of family caregivers to be present to partner in the care of loved ones. Building on the success of the "Better Together" campaign, Healthcare Excellence Canada - the newly amalgamated organization of the Canadian Foundation for Healthcare Improvement and the Canadian Patient Safety Institute - has co-developed policy guidance and "Essential Together" programming that recognizes the significant role of essential care partners. This work aims to support the safe reintegration of essential care partners into health and care organizations across Canada during the pandemic and beyond.

Molecular underpinnings of integrin binding to collagen-mimetic peptides containing vascular Ehlers-Danlos syndrome-associated substitutions.

Collagens carry out critical extracellular matrix (ECM) functions by interacting with numerous cell receptors and ECM components. Single glycine substitutions in collagen III, which predominates in vascular walls, result in vascular Ehlers-Danlos syndrome (vEDS), leading to arterial, uterine, and intestinal rupture and an average life expectancy of <50 years. Collagen interactions with integrin αβ are vital for platelet adhesion and activation; however, how these interactions are impacted by vEDS-associated mutations and by specific amino acid substitutions is unclear.
