Valve-in-Valve Transcatheter Aortic Valve Replacement Versus Redo-Surgical Aortic Valve Replacement in Patients With Aortic Stenosis: A Systematic Review and Meta-analysis.

Aortic stenosis is a common and significant valve condition requiring bioprosthetic heart valves with transcatheter aortic valve replacement (TAVR) being strongly recommended for high-risk patients or patients over 75 years. This meta-analysis aimed to pool existing data on postprocedural clinical as well as echocardiographic outcomes comparing valve-in-valve (ViV)-TAVR to redo-surgical aortic valve replacement to assess the short-term and medium-term outcomes for both treatment methods. A systematic literature search on Cochrane Central, Scopus, and Medline (PubMed interface) electronic databases from inception to August 2023.

A comparative analysis of feature selection models for spatial analysis of floods using hybrid metaheuristic and machine learning models.

The research aims to propose a feature selection model for hydraulic analysis as such a model has not been proposed previously. For this purpose, hybrids of three metaheuristic algorithms, particle swarm optimization (PSO), ant colony optimization (ACO), and genetic algorithm (GA) with two machine learning models which are support vector machine (SVM) and K-nearest neighbor (KNN) are employed. The dataset considered was hydraulic having an association with flood and possessed topographic, geo-environmental, and human-induced variables.

Rapid Presumptive Identification of and Clinical Isolates Using a Highly Specific Lateral Flow Assay.

We conducted a comprehensive, multiphase laboratory evaluation of the InBios Active Melioidosis Detect (AMD) rapid test, a lateral flow immunoassay designed to detect capsular polysaccharides produced by or , used in conjunction with the Omni Array Reader for the rapid identification of culture isolates of or to support clinical diagnosis for response and triage during a mass casualty event, such as a biological attack. The study was conducted at 2 sites to assess the performance of the AMD test. The sensitivity, specificity, and reproducibility of the assay was determined using 5 replicates of 35 inclusivity strains and 64 clinical background strains.

Validation of a Lateral Flow Test for the Presumptive Identification of the Presence of or in Environmental Samples.

We conducted a comprehensive, multiphase laboratory evaluation of InBios Active Melioidosis Detect (AMD) rapid test, a lateral flow immunoassay designed to detect capsular polysaccharides produced by or , used in conjunction with the Omni Array Reader (OAR) for the rapid detection of or in environmental (nonclinical) samples at 2 sites. The limit of detection, using reference strains strain ATCC 23344 and strain ATCC 11668, was determined to be 10 to 10 CFU/mL. In different phases of the evaluation, inclusivity strains that included geographically diverse strains of (N = 13) and (N = 22), geographically diverse phylogenetic near neighbor strains (N = 66), environmental background strains (N = 64), white powder samples (N = 26), and environmental filter extracts (N = 1 pooled sample from 10 filter extracts) were also tested.
