Effects of Spinal Cord Stimulation in Patients with Small Fiber and Associated Comorbidities from Neuropathy After Multiple Etiologies.

The aim of this study was to evaluate the effects of spinal cord stimulation (SCS) on pain, neuropathic symptoms, and other health-related metrics in patients with chronic painful peripheral neuropathy (PN) from multiple etiologies. A prospective single center observational longitudinal cohort study assessed SCS efficacy from April 2023 to May 2024, with follow-ups at 2, 4, 6, and 12 months in 19 patients suffering from the painful polyneuropathy of diverse etiologies: diabetic (DPN), idiopathic (CIAP), chemotherapy-induced (CIPN), and others. Patients were implanted with a neurostimulator (WaveWriter Alpha, Boston Scientific Corporation, Valencia, CA, USA) and percutaneous leads targeting the lower limbs (T10-T11) and, if necessary, the upper limbs (C4-C7).

Health-related quality of life in people with HIV from the multicentre CoRIS cohort in Spain: Associated factors and short-term changes over time.

Objectives: We aimed to describe health-related quality of life (HRQoL), overall and across its dimensions, identify associated factors, and assess changes over time among people with HIV (PWH) from the Spanish multicentre CoRIS cohort.

Methods: We developed a mobile app to collect HRQoL data every 3 months using the WHOQOL-HIV-BREF questionnaire (31 items across six domains), among PWH followed in CoRIS in 2021-2023. Factors associated with good/very good global HRQoL and with domain-specific mean scores were identified using multivariable logistic and linear regression, respectively.

Influence of Graphene Oxide on Mechanical and Morphological Properties of Nafion Membranes.

This study explored the influence of graphene oxide (GO) on morphological and mechanical properties of Nafion 115 membranes with the objective of enhancing the mechanical properties of the most widely employed membrane in Proton Exchange Membrane Water Electrolyzers (PEMWE) applications. The membrane surface was modified by ultrasonically spraying a GO solution and different annealing temperatures were tested. Scanning Electron Microscopy (SEM) cross-sectional images revealed that annealing the composite membranes was sufficient to favor an interaction between the graphene oxide and the surface of the Nafion membranes.

Graphene-Based Fiber Materials for Gas Sensing Applications: State of the Art Review.

The importance of gas sensors is apparent as the detection of gases and pollutants is crucial for environmental monitoring and human safety. Gas sensing devices also hold the potential for medical applications as health monitoring and disease diagnostic tools. Gas sensors fabricated from graphene-based fibers present a promising advancement in the field of sensing technology due to their enhanced sensitivity and selectivity.

Controlling the Optical and Electrical Properties of Perovskite Films and Enhancing Solar Cell Performance Using the Photonic Curing Process.

The most common method of processing metal oxide and perovskite thin films in the laboratory is thermal annealing (TA), which is a constraint for the commercialization of large-scale perovskite solar cells. Here, we present a photonic curing (PC) process to produce fully photonically annealed perovskite cells-a fast process with well-controlled, short light pulses-to develop perovskite photovoltaic devices with high efficiency. We also demonstrate how to use the parameters of the photonic annealing system to control the optical, electrical, morphological, and structural properties of perovskite layers for photovoltaic device applications.
