An MRI assessment of mechanisms underlying lesion growth and shrinkage in multiple sclerosis.

Objective: To assess the pathological mechanisms contributing to white matter (WM) lesion expansion or contraction and remyelination in multiple sclerosis (MS).

Methods: We assessed 1,613 lesions in 49 people with relapsing-remitting MS in the CCMR-One bexarotene trial (EudraCT 2014-003145-99). We measured lesion orientation relative to WM tracts, surface-in gradients and veins.

Negative Pressure Dressings to Prevent Surgical Site Infection After Emergency Laparotomy: The SUNRRISE Randomized Clinical Trial.

Importance: Patients undergoing unplanned abdominal surgical procedures are at increased risk of surgical site infection (SSI). It is not known if incisional negative pressure wound therapy (iNPWT) can reduce SSI rates in this setting.

Objective: To evaluate the effectiveness of iNPWT in reducing the rate of SSI in adults undergoing emergency laparotomy with primary skin closure.

A period prevalence study of palliative care need and provision in adult patients attending hospital-based dialysis units.

Background: Advanced chronic kidney disease is a life-limiting disease that is known to benefit from palliative care. Unmet palliative care need in patients with kidney failure is commonly reported but the level of need among patients receiving haemodialysis is unknown.

Methods: A period prevalence study of adult patients attending two hospital-based dialysis units was conducted.

A Cross-Species Atlas of the Dorsal Vagal Complex Reveals Neural Mediators of Cagrilintide's Effects on Energy Balance.

Amylin analogs, including potential anti-obesity therapies like cagrilintide, act on neurons in the brainstem dorsal vagal complex (DVC) that express calcitonin receptors (CALCR). These receptors, often combined with receptor activity-modifying proteins (RAMPs), mediate the suppression of food intake and body weight. To understand the molecular and neural mechanisms of cagrilintide action, we used single-nucleus RNA sequencing to define 89 cell populations across the rat, mouse, and non-human primate caudal brainstem.
