Implementation of real time three-dimensional transesophageal echocardiography in percutaneous mitral balloon valvuloplasty and structural heart disease interventions. | LitMetric
Percutaneous interventions for structural heart disease are performed in a dynamic and complex environment that necessitates multiple imaging modalities to achieve procedural success. Structural interventions are routinely guided by two-dimensional (2D) modalities such as x-ray fluoroscopy, transesophageal echocardiography (TEE), and intracardiac echocardiography. Real time imaging with three-dimensional (3D) echocardiography is a novel method of guidance to facilitate complex structural interventions with the promise of greater safety and efficacy. Real time 3D TEE (RT3D-TEE) affords the capability of imaging catheters and devices, the interventional objective, and adjacent structures simultaneously. We present an overview of RT3D-TEE and explore its functionality in structural heart interventions by using percutaneous mitral balloon valvuloplasty as a model.
Objective: Electroencephalography (EEG) and Magnetoencephalography (MEG) are widely used non-invasive techniques in clinical and cognitive neuroscience. However, low spatial resolution measurements, partial brain coverage by some sensor arrays, as well as noisy sensors could result in distorted sensor topographies resulting in inaccurate reconstructions of underlying brain dynamics. Solving these problems has been a challenging task, This paper proposes a robust framework based on electromagnetic source imaging for interpolation of unknown or poor quality EEG/MEG measurements.
Background: As Alzheimer disease (AD) and AD-related dementias (ADRD) progress, individuals increasingly require assistance from unpaid, informal caregivers to support them in activities of daily living. These caregivers may experience high levels of financial, mental, and physical strain associated with providing care. CareVirtue is a web-based tool created to connect and support multiple individuals across a care network to coordinate care activities and share important information, thereby reducing care burden.
Focusing on three specific organizations-The Terrence Higgins Trust (THT), Blackliners, and The NAZ Project (Naz)-this article explores the different ways in which voluntary organizations responded to Black gay men (BGM) in Britain during the AIDS crisis from the 1980s to 2000. Illustrating how the place of BGM in Britain at this time was multidimensional and often contradictory, the first section demonstrates how they required safer-sex messaging that took account of the heterogeneous ways in which they experienced the intersection of racism and homophobia. Situated in this context, the second section explores for the first time the well-documented work of THT as it applied to BGM.

Background: Computer-assisted fluoroscopic navigation and robotic technologies aim to optimize implant placement and alignment in primary total hip arthroplasty (THA) to improve patient outcomes. This study uses a retrospective hospital billing database covering 1,300 hospitals to compare the clinical and economic effect of these technologies.
Methods: The study compared patients undergoing THA with robotic versus computer-assisted fluoroscopic navigation technologies between January 1, 2016, and September 30, 2021, using the Premier Healthcare Database.
Hopfield neural networks (HNNs) promise broad applications in areas such as combinatorial optimization, memory storage, and pattern recognition. Among various implementations, optical HNNs are particularly interesting because they can take advantage of fast optical matrix-vector multiplications. Yet their studies so far have mostly been on the theoretical side, and the effects of optical imperfections and robustness against memory errors remain to be quantified.
