The Influence of Physiological Blood Clot on Osteoblastic Cell Response to a Chitosan-Based 3D Scaffold-A Pilot Investigation.

Background: The use of ex vivo assays associated with biomaterials may allow the short-term visualization of a specific cell type response inserted in a local microenvironment. Blood is the first component to come into contact with biomaterials, providing blood clot formation, being substantial in new tissue formation. Thus, this research investigated the physiological blood clot (PhC) patterns formed in 3D scaffolds (SCAs), based on chitosan and 20% beta-tricalcium phosphate and its effect on osteogenesis.

How I do it: using physics and progressive defect tensioning to close large hernia defects during MIS ventral hernia repair.

Introduction: Closure of large hernia defects with minimally invasive surgery has long-been a challenge. Barbed sutures have helped us bridge this technical gap, but their off-label use is not well studied.

Materials And Methods: We describe a suturing technique for minimally invasive ventral hernia repair (MIS-VHR) termed "progressive defect tensioning" and explore its theoretical advantages.

Pelvis Or Involved Node Treatment: Eradicating Recurrence in Prostate Cancer (POINTER-PC) - study protocol paper for a phase III multicentre, open-label randomised controlled trial.

Introduction: Prostate cancer (PCa) is the most common cancer in men. Recurrence may occur in up to half of patients initially treated with curative intent for high-risk localised/locally advanced PCa. Pelvic nodal recurrence is common in this setting, but no clear standard of care exists for these patients, with potential therapeutic approaches including stereotactic body radiotherapy (SBRT) to the involved node(s) alone, extended nodal irradiation (ENI) to treat sites of potential micrometastatic spread in addition to involved node(s) and androgen deprivation therapy with or without additional systemic anticancer therapies.

Reasons for organ and tissue donation refusal and opposition: a scoping review.

Objective: To map the reasons why individuals oppose or refuse organ and tissue donation, from an international perspective.

Methods: A scoping review was conducted from May 2022 to February 2024 using a three-stage search strategy across five databases and Google Scholar. Data analysis involved categorizing information based on similarities and populations studied.
