Securement of Tracheostomy Collar After Free Flap Surgery for Patients With Head And Neck Cancer.

Background: For patients with head and neck cancer who have undergone microvascular free flap surgery, securing a tracheostomy collar onto the neck using the traditional method (ie, with tracheostomy ties) is contraindicated because the ties may compress the newly vascularized tissue. However, no clear guidance exists for the use of other methods in these patients. Current techniques often use safety pins, which can cause injury to staff members.

Medical learner perspectives on elements of an educational rural generalist pathway: survey outcomes.

Introduction: The Northern Ontario School of Medicine University (NOSM U) continues to be challenged in meeting its social accountability mandate of addressing the rural health human resource crises in its catchment of Northern Ontario. Its new educational initiative, the Rural Generalist Pathway (RGP) aims to graduate family physicians specifically prepared for rural practice. This study elicits the perspective of NOSM U learners on the various components being considered for this educational pathway.

Similarities of metabolomic disturbances in prematurity-associated obstructive lung disease to chronic obstructive pulmonary disease.

Prematurity-associated lung disease (PLD) is a long-term consequence of preterm-birth. Since the underlying mechanisms of PLD remain poorly characterised, we compared the urinary metabolome between recently described spirometry phenotypes of PLD. Preterm- and term-born children aged 7-12 years, from the Respiratory Health Outcomes in Neonates (RHiNO) cohort, underwent spirometry and urine collection.

AI driven analysis of MRI to measure health and disease progression in FSHD.

Facioscapulohumeral muscular dystrophy (FSHD) affects roughly 1 in 7500 individuals. While at the population level there is a general pattern of affected muscles, there is substantial heterogeneity in muscle expression across- and within-patients. There can also be substantial variation in the pattern of fat and water signal intensity within a single muscle.

Novel 3D MRI-based volumetric assessment of rotator cuff musculature demonstrates stronger correlation with preoperative functional status when compared to the Goutallier grading scheme.

Background: The Goutallier classification (GC) is used to assess fatty atrophy in rotator cuff (RC) tears, yet limitations exist. A battery of 3-dimensional (3D) magnetic resonance imaging (MRI) volumetric scores (VSs) was developed to provide comprehensive characterization of RC pathology. The purposes of this study were to (1) describe the correlation between GC and VSs for supraspinatus changes in RC tears, (2) characterize the chronicity of RC tears using a battery of 12 VS measurements, and (3) compare GC and VSs to determine which method most closely corresponds with preoperative patient-reported outcome measures (PROMs).
