Article Abstract
Catheter infection is the most common complication after vascular catheter placement, which seriously threatens the survival of critically ill patients. Although catheters with antibacterial drug coatings have been used, catheter infections have not been effectively resolved. In this research, a SiO nanosphere-coated PTFE catheter (PTFE-SiO) with enhanced antibacterial and excellent mechanical properties was prepared dopamine as a graft bridge. The microscopic morphology results show that the nanospheres are uniformly dispersed on the surface of the catheter. The physicochemical characterization confirmed that PTFE-SiO had reliable bending resistance properties, superhydrophobicity, and cytocompatibility and could inhibit thrombosis. Antibacterial results revealed that PTFE-SiO could hinder the reproduction of and . This research demonstrates the hydroxyl-rich materials obtained by hydroboration oxidation have the advantages of better dispersion of functional coatings, indicating their potential for helpful modification of catheters.

Exercise-induced arterial hypoxaemia in patients with heart failure with preserved ejection fraction.
J Physiol
September 2025
Institue for Exercise and Environmental Medicine, Texas Presbyterian Hospital, Dallas, TX, USA.
Some patients with heart failure with preserved ejection fraction (HFpEF) have demonstrated evidence of exercise-induced arterial hypoxaemia (EIAH). However, EIAH was not quantified using , , and measurements as previously conducted in healthy adults nor was EIAH quantified alongside simultaneous measurements of pulmonary vascular pressures, cardiorespiratory responses, or dyspnoea on exertion (DOE) in these patients. Given the effects of hypoxaemia on pulmonary vasoconstriction, cardiorespiratory responses, and DOE, we tested the hypothesis that patients with HFpEF and EIAH (EIAH) would demonstrate higher pulmonary vascular pressures, worse oxygen uptake, and greater DOE compared with patients without EIAH (EIAH).

Division of Gastroenterology, Department of Medicine, Toronto General Hospital, University of Toronto, University Health Network, Toronto, Ontario, Canada.
Background: Intravenous lipid emulsions are a key component of parenteral nutrition, and their fatty acid compositions may influence immune responses and clinical outcomes.
Methods: This retrospective cohort study conducted from January 2020 to December 2022 compared clinical outcomes of hospitalized non-critical care patients receiving parenteral nutrition with either mixed oil or soybean oil lipid emulsions for at least 48 h. The primary outcome was a composite of the presence of pneumonia, urinary tract infection, or an intra-abdominal collection diagnosed within 14 days of initiating parenteral nutrition.
Standarization and characterization of intravenous drug dilutions in critically ill pediatric patients.
Farm Hosp
September 2025
Servicio de Farmacia, Hospital Universitario de Toledo, Toledo, Spain.
Objective: To standardize the drug dilutions administered intravenously in a Pediatric Intensive Care Unit and to characterize these dilutions based on their pH, osmolarity, and vesicant nature. This aims to guide the selection of the most appropriate vascular access device, minimizing associated complications, and preserving the patient's venous capital.
Methods: Through a consensus between Pharmacy and Pediatric Services, the most frequently administered intravenous drugs in the Pediatric Intensive Care Unit were selected.
Ethanol Infusion of the Vein of Marshall in Catheter Ablation of Persistent Atrial Fibrillation in Patients with Mitral Valve Replacement.
Heart Rhythm
September 2025
Department of Cardiology, Beijing Anzhen Hospital, Capital Medical University, Beijing Institute of Heart Lung and Blood Vessel Diseases, Beijing, China. Electronic address:
Background: The effectiveness of ethanol infusion of the vein of Marshall (EIVOM) for persistent atrial fibrillation (AF) in patients with mitral valve replacement (MVR) remains to be determined.
Objectives: This study investigated the effectiveness and safety of EIVOM in catheter ablation of persistent AF in patients with MVR.
Methods: This is a retrospective case-control study.
Floating wire assisted device retrieval-a novel technique for prevention of guide-related coronary injury.
Indian Heart J
September 2025
Department of Medicine, Fortis Hospital, Kangra, India.
Background: An inward force is experienced by the guide catheter during device retrieval resulting in potential risk of deep engagement into the ostio-proximal coronary segment. This undesired movement can result in coronary injury. There is no systematic data or reports of techniques to prevent such inadvertent guide movement during difficult retrieval of devices.
