Rural Canadian emergency physician experiences using point-of-care ultrasound.

Objectives: Point-of-care ultrasound (POCUS) is a rapidly evolving and clinically significant skill set that has potential for improving patient care for the approximately 7 million Canadians living in rural and under-resourced environments. A national appraisal of rural POCUS training and utilization is needed to understand barriers to funding and training for rural emergency physicians in Canada. The primary objective of this study was to determine the current level of training and types of POCUS utilization by rural emergency physicians in Canada.

Origin of Langerhans cells in normal skin and chronic GVHD after hematopoietic stem-cell transplantation.

Chronic graft-versus-host disease (cGVHD) is a common complication following allogeneic stem-cell transplantation (SCT). Past studies have implicated the persistence of host antigen-presenting cells (APCs) in GVHD. Our objective was to determine the frequency of host Langerhans cells (LCs) in normal skin post-SCT and ask if their persistence could predict cGVHD.
