High-Throughput Exploration of Ti-V-Nb-Mo Carbide MXenes Using Neural Network Potentials and Their Evaluation as Catalysts for Hydrogen Evolution Reaction.

Realization of a sustainable hydrogen economy in the future requires the development of efficient and cost-effective catalysts for its production at scale. MXenes (MX) are a class of 2D materials with 'n' layers of carbon or nitrogen (X) interleaved by 'n+1' layers of transition metal (M) and have emerged as promising materials for various applications including catalysts for hydrogen evolution reaction (HER). Their properties are intimately related to both their composition and their atomic structure.

Non-steroidal anti-inflammatory drugs for treating symptomatic uncomplicated urinary tract infections in non-pregnant adult women.

Background: Almost half of all women will have at least one symptomatic urinary tract infection (UTI) in their lifetime. Although usually self-remitting, 74% of women contacting a health professional are prescribed an antibiotic, and in rare instances, they may progress to more severe infections. Therefore, the standard of care for the treatment of symptomatic uncomplicated UTIs is oral antibiotic therapy, which aims to achieve symptom resolution and prevent the development of complications such as pyelonephritis.

Successful Endoscopic Management of Complete Tracheal Occlusion in a Child.

Prolonged mechanical ventilation following cardiopulmonary and neurological events oftentimes necessitates a tracheostomy and tracheal granulation is one of its most common late complications. The literature recommends that large granulation be managed through surgical excision or endoluminal techniques. A 6-year-old boy presented with high-grade tracheal stenosis secondary to endotracheal cuff-related injury and prolonged tracheostomy.

Stigma, depression, and quality of life among people with pulmonary tuberculosis diagnosed through active and passive case finding in Nepal: a prospective cohort study.

Background: The psychosocial consequences of tuberculosis (TB) are key barriers to ending TB globally. We evaluated and compared stigma, depression, and quality of life (QoL) among people with TB diagnosed through active (ACF) and passive (PCF) case-finding in Nepal.

Methods: We prospectively recruited adults with TB diagnosed through ACF and PCF in four districts of Nepal between August 2018 and April 2019.

Healthcare providers' and community stakeholders' perception of using drones for tuberculosis diagnosis in Nepal: an exploratory qualitative study.

Background: In rural Nepal, poor road and transport networks and few testing laboratories impede tuberculosis diagnosis. A drone transport system was established to transport sputum samples to laboratories with advanced molecular diagnostic machines - GeneXpert MTB/RIF. This study explored the perceptions of using drones for tuberculosis diagnosis among community stakeholders, female community health volunteers, and healthcare providers from communities with drones implemented and without drone programs.
