Atrial fibrillation (AF) is common and is a prominent risk factor for ischemic stroke. Oral anticoagulant (OAC) therapy has been the main strategy for stroke prevention in AF patients; however, OAC therapy carries a bleeding risk and is not tolerated by all patients. Left atrial appendage (LAA) closure offers a non-pharmacological alternative for stroke prevention in patients with non-valvular AF. In this update, an overview of current and emerging LAA occluders is given - with special attention to the key design features of every single device and, if available, preclinical or clinical data.

Purpose: Immunoglobulin G4-related disease (IgG4-RD) is a complex systemic fibroinflammatory condition with different clinical manifestations affecting multiple organ systems. Despite its rarity, the disease presents diagnostic and therapeutic challenges due to its mimicry of malignancies and other immune-mediated disorders. The 2019 American College of Rheumatology/European League Against Rheumatism Classification Criteria for IgG4-Related Disease is the current state of art to confirm the diagnosis of IgG4-RD even in the absence of histological analysis.

Introduction: Liquid biopsy as a non-invasive method to investigate cancer biology and monitor residual disease has gained significance in clinical practice over the years. Whilst its applicability in carcinomas is well established, the low incidence and heterogeneity of bone and soft tissue sarcomas explains the less well-established knowledge considering liquid biopsy in these highly malignant mesenchymal neoplasms.

Materials And Methods: A systematic literature review adhering to the PRISMA guidelines initially identified 920 studies, of whom 68 original articles could be finally included, all dealing with clinical applicability of liquid biopsy in sarcoma.

Exudate management is essential for creating a moist wound environment that promotes optimal healing, especially in highly exuding wounds, where choosing an appropriate wound dressing to handle high volumes of exudate is a key part of the wound management strategy. Superabsorbent wound dressings (SWDs) have been designed to absorb and retain large amounts of exudate. Thus, they are advocated for management of wounds with moderate-to-high levels of exudate to reduce the risk of leakage and damage to the periwound skin.

Type 2 diabetes (T2D) is a complex condition characterised by the interaction between insulin resistance and beta cell dysfunction. C-peptide, a key biomarker of endogenous insulin secretion, has a role in diagnosing type 1 diabetes (T1D). However, its utility in T2D has not been extensively studied.

This review aims to focus on what we know about the management of biliary strictures of unknown etiology, especially exploring our diagnostic armamentarium in the setting of indeterminate biliary strictures. Presently, this is a current issue that has a relevant impact both on patient prognosis, often delaying diagnosis, and on overall costs associated with repeating diagnostic procedures, sometimes performed with very expensive devices. We also focus on current biliary drainage approaches, providing an overview of therapeutic options, endoscopic or not.
