Fate of Semilunar Valves From Discarded Hearts at the Time of Pediatric Heart Retransplantation.

Background: Partial heart transplantation (PHT) is a novel procedure for children in need of a growing valve replacement option. One challenge is identifying suitable donor valves. Semilunar heart valves from patients receiving a retransplant may be a source, however their functionality and growth potential especially at the time of retransplant are unknown.

Advantages of the standardized use of preoperative fascia iliaca block versus conventional analgesia in older adults with fragility hip fracture: A retrospective cohort study at two hospitals in Colombia.

Hospital admission due to fragility hip fracture has increased significantly in recent years. In patients with hip fracture, perioperative pain management is usually with opioids, whose dosage is difficult to adjust and have many side effects, especially in older adults. The purpose of this study was to determine the impact and the advantages of the implementation of the fascia iliaca blockade in older adults with hip fracture due to fragility included in the Orthogeriatric Clinical Care Center of the Fundación Santa Fe de Bogotá and the San José Infantil University Hospital in Bogotá, Colombia.

A pipeline for harmonising NHS Scotland laboratory data to enable national-level analyses.

Objective: Medical laboratory data together with prescribing and hospitalisation records are three of the most used electronic health records (EHRs) for data-driven health research. In Scotland, hospitalisation, prescribing and the death register data are available nationally whereas laboratory data is captured, stored and reported from local health board systems with significant heterogeneity. For researchers or other users of this regionally curated data, working on laboratory datasets across regional cohorts requires effort and time.

Future Trends in Alternative Sustainable Materials for Low-Temperature Thermoelectric Applications.

In the evolution of pervasive electronics, it is imperative to significantly reduce the energy consumption of power systems and embrace sustainable materials and fabrication processes with minimal carbon footprint. Within this context, thermoelectric generators (TEGs) have garnered substantial attention in recent years because of the readily available thermal gradients in the environment, making them a promising energy-harvesting technology. Current commercial room-temperature thermoelectrics are based on scarce, expensive, and/or toxic V-VI chalcogenide materials, which limit their widespread use.

Numerical Simulation of Light to Heat Conversion by Plasmonic Nanoheaters.

Plasmonic nanoparticles are widely recognized as photothermal conversion agents, i.e., nanotransducers or nanoheaters.
