Vacuum-assisted closure (VAC) is a wound management system that exposes a wound bed to local negative pressure to promote healing. Benefits of VAC therapy include removal of fluid from the extravascular space, improved circulation, enhanced granulation tissue formation, and increased bacterial clearance. VAC therapy has been used extensively in human patients to treat a variety of acute and chronic wound conditions. This article reviews the use of VAC therapy in a variety of wound conditions and describes our experiences with using VAC therapy in dogs and cats at the University of Florida.

A Qualitative Evaluation of Two Electronic-Rehabilitation Programmes for Managing Persistent Knee Pain.
Musculoskeletal Care
March 2025
Clinical Trials Research Unit, University of Leeds, Leeds, UK.
Introduction: Persistent knee pain often due to knee osteoarthritis (OA) is a highly prevalent and disabling condition. Electronic-rehabilitation (e-rehab) programmes have the potential to support self-management of knee OA. This study aimed to evaluate user engagement and acceptability of two e-rehab programmes, Group e-rehab, a remote physiotherapy-led programme and My Knee UK, a self-directed web-based exercise programme.

Br J Health Psychol
February 2025
Health Psychology Section, Institute of Psychiatry, Psychology and Neuroscience, King's College London, London, UK.
Objectives: This study aims to explore patients' and clinicians' understanding and experiences of refractory disease (RD) and persistent physical and emotional symptoms (PPES) in patients with inflammatory arthritis (IA), namely rheumatoid arthritis or polyarticular juvenile idiopathic arthritis from their perspectives through interviews and/or focus groups.
Design: A qualitative study was conducted, following a pragmatic epistemology approach with framework analysis employed.
Methods: Semi-structured interviews or focus groups with IA patients (n = 25) and multi-disciplinary rheumatology HCPs (n = 32) were conducted at one time point to obtain participants respective understanding and experiences of managing RD/PPES, and its impact on the patient-professional relationship.
Humoral immune response to SARS-CoV-2 vaccines in patients with autoimmune rheumatic diseases.
Arch Med Res
January 2025
Servicio de Reumatología, Hospital Angel Cruz Padilla, Tucumán, Argentina.
Background: Patients with autoimmune rheumatic diseases (ARD) are at increased risk of infection due to their impaired immune response, which also reduces vaccination efficacy. Although several studies have evaluated the serological response to SARS-CoV-2 mRNA-based vaccines in patients with ARD, limited information on immune responses to other vaccination platforms is available.
Aims: This observational prospective study aims to investigate the humoral immune response to different SARS-CoV-2 vaccines in patients with ARD.

Calcinosis cutis affects 20-40% of patients with systemic sclerosis. This study tests the hypothesis that calcium-chelating polycarboxylic acids can induce calcium dissolution without skin toxicity or irritancy. We compared citric acid (CA) and ethylenediaminetetraacetic acid (EDTA) to sodium thiosulfate (STS) for their ability to chelate calcium in vitro using a pharmaceutical dissolution model of calcinosis (hydroxyapatite (HAp) tablet), prior to evaluation of toxicity and irritancy in 2D in vitro skin models.
