Utilization of ventricular assist device (VAD) support in patients with end-stage heart failure is well advanced. Recent studies emphasize the need to develop and evaluate evidence-based psychosocial support interventions for patients following VAD implantation.

Left ventricular assist device (LVAD) therapy may lead to an aortic regurgitation, limiting left ventricular unloading and causing adverse events. Whether concomitant aortic valve replacement may improve outcomes in patients with preoperative mild-to-moderate aortic regurgitation remains unclear.

Preclinical and clinical studies have demonstrated the advantages of oxygenated hypothermic machine perfusion (HMPO) during kidney preservation. However, the optimal oxygenation levels during HMPO remain undetermined. The aim of this study was to compare different levels of oxygenation (0%, 21%, 50%, and 100%) during 22 h of active oxygenated HMP (HMPO) using oxygen preloading by bubbling oxygenation in the preservation solution and continuous surface oxygenation during MP in a porcine DCD model.

This study was designed to evaluate the long-term durability, oxygenation, and pressure loss of newly developed, methacryloyloxyethyl phosphorylcholine (MPC)-polymer-coated, nonporous silicone hollow fiber-membrane lungs in vivo using a pulmonary artery-to-left-atrium paracorporeal configuration.

Peripheral veno-arterial extracorporeal membrane oxygenation (ECMO) is a powerful life-saving tool; however, it can sometimes induce severe pulmonary edema in patients with critical heart failure. We report favorable outcomes in critically ill patients by using a central ECMO system with an innovative blood perfusion method.

The cost and complexity associated with animal testing are significantly reduced by using mock circulatory loops prior. Novel mock circulatory loops allow us to test biomedical devices preclinically due to their flexibility, scalability, and cost-effectiveness. The presented work describes the development of a hardware-in-the-loop platform to emulate human physiology for the Istanbul Heart (iHeart-II) LVAD.

The interleukin 1 (IL-1) cytokine group plays a key role in sterile inflammation and may be an important target for transplant-related renal injury. This study examined the effects of anakinra, a non-specific IL-1 receptor antagonist, administered during normothermic machine perfusion (NMP) of porcine kidneys.

The utilization of extracorporeal liver support systems is increasingly prevalent for the management of acute-on-chronic liver failure in clinical settings. Yet, the efficacy of these interventions in terms of tangible clinical benefits for patients remains a matter of debate, underscoring the need for meta-analysis.

To analyze the clinical outcomes of extracorporeal membrane oxygenation (ECMO) support in children with congenital heart disease (CHD) after surgery and explore the risk factors associated with mortality during long-term follow-up for 3-5 years.

Liver transplantation (LT) is still limited by organ shortage and post-transplant monitoring issues. While machine perfusion techniques allow for improving organ preservation, biomarkers like donor-derived cell-free DNA (dd-cfDNA) and mitochondrial cfDNA (mt-cfDNA) may provide insights into graft injury and viability pre- and post-LT.

There is a lack of documented cases regarding complications during ECMO transfer in middle-income countries. Using portable ECMO devices facilitates patient transport but entails significantly higher costs, necessitating evidence of their practical utility. This study aims to describe complications during ECMO transfer in Argentina and to compare complication rates between the integrated portable ECMO and non-portable ECMO systems.

The objective of this study is to determine the incidence of major bleeding events in patients implanted with continuous flow left ventricular assist devices (CF-LVADs) bridged with enoxaparin (LMWH) compared to intravenous unfractionated heparin (IV UFH) for a subtherapeutic INR on warfarin.

Artificial anal sphincter is a novel method for the treatment of fecal incontinence. Aiming at the problems of complex mechanical structure, high mechanical failure rate, large volume and poor biocompatibility of existing artificial anal sphincters, this article proposes a novel flexible artificial anal sphincter with bionic structure.

Tracheal decellularization is one of the main processes to provide tracheal substitutes for tracheal replacement. Recently, studies have been held for agents and combinations of processes for tracheal decellularization with different outcomes. This study aimed to evaluate the efficacy of tracheal decellularization by the immunogenic cellular elements using residual deoxyribonucleic acid (DNA) contents (ng/mg) and the preservation of biomechanical integrity by glycosaminoglycan (GAG) content (μg/mg), modulus tensile strength (MPa), ultimate tensile strength (MPa), and stress loading of 50% deformation (N).

Visual impairment has been augmented by glasses for centuries. With the advent of newer technologies, correction of more severe visual impairment may be possible with brain-computer interface and eye implants.

Normothermic machine perfusion (NMP) is a technique for donor liver preservation and assessment in transplantation. NMP has gained momentum recently by enabling safer use of higher risk organs via organ viability assessment. It also offers a platform for investigating ex vivo organ biology.

Appropriate anticoagulation is crucial for the success of left ventricular assist device patients. Currently, there is no consensus on the optimal management of their subtherapeutic INR in ambulatory setting. Our goal is to evaluate both the short-term adverse events and long-term outcomes of enoxaparin bridging at a major transplant center, following the implementation of bridging safety criteria.

Casualties of military conflicts suffer a multitude of injuries, and recent research has documented a significant number develop acute respiratory distress syndrome (ARDS). The present study undertakes a scoping review of research on the treatment of ARDS in combat casualties near the battlefield.

An innovative solution has been recently proposed for the treatment of heart failure with preserved ejection fraction (HFpEF), using a centrifugal mechanical circulatory support (MCS) device. We sought firstly to assess the hemocompatibility of the proposed device. HFpEF treatment requires the blood pump to operate at low blood flow rate (0.05-0.5 L/min). Given high blood trauma expected in these conditions, we sought secondly to investigate design improvements in order to reduce this risk.
