Objective: In recent years, wearable devices such as smartwatches and smart patches have revolutionized biosignal acquisition and analysis, particularly for monitoring electrocardiography (ECG). However, the limited power supply of these devices often precludes real-time data analysis on the patch itself.

Approach: This paper introduces a novel Python package, tinyHLS (High Level Synthesis), designed to address these challenges by converting Python-based AI models into platform-independent hardware description language (HDL) code accelerators.

Background: Asymptomatic nonvalvular atrial fibrillation is often suspected in patients with cryptogenic stroke which constitute 20%-30% of ischemic strokes. Detection of atrial fibrillation (AF) and treatment with anticoagulation can reduce the risk of stroke. We sought to investigate the prevalence of asymptomatic atrial fibrillation (aAF) in patients with a history of stroke or an acute stroke on admission.

Modern brain-computer interfaces and neural implants allow interaction between the tissue, the user and the environment, where people suffer from neurodegenerative diseases or injuries.This interaction can be achieved by using penetrating/invasive microelectrodes for extracellular recordings and stimulation, such as Utah or Michigan arrays. The application-specific signal processing of the extracellular recording enables the detection of interactions and enables user interaction.

Article Synopsis
  • - The study aimed to determine which medical conditions lead to 30-day readmissions, identify patient characteristics that benefit from outpatient follow-up, and assess how timely follow-up impacts readmission risk within a Miami Integrated Health-Community Paramedicine (MIH-CP) program in Baltimore.
  • - Analysis showed that timely outpatient follow-up significantly reduced readmission risks for patients under 50 and those with fewer than 5 social health needs, but no specific chronic disease exacerbations linked to readmission were found.
  • - The research suggested that focusing on younger patients and those with less social complexity may enhance policies and programs designed to reduce 30-day readmissions, although an ideal follow-up timeframe was not determined.

We demonstrate the development of a label-free, impedance-based biosensor by using a passivation layer of 50-nm tantalum pentoxide (TaO) on interdigitated electrodes (IDE). This layer was fabricated by atomic layer deposition (ALD) and has a high dielectric constant (high-κ), which improves the capacitive property of the IDE. We validate the biosensor's performance by measuring uromodulin, a urine biomarker for kidney tubular damage, from artificial urine samples.

Future retinal implants will require a stimulation selectivity between different sub-types of Retinal Ganglion Cells (RGCs) to evoke natural perceptions rather than phosphenes in patients. To achieve this, a cell-type specific stimulation pipeline is required that identifies target RGC sub-types from recorded input images and extracts the specific stimulation parameters to activate this cell-type selectively. Promising biological experiments showed that ON-/OFF- sustained/transient RGCs could be selectively activated by modulating repetition rate and amplitude of an electrical stimulation current in the kilohertz range.

Many countries around the world face a shortage of medical personnel, leading to work overload or even burnout. This calls for political and scientific solutions to relieve the medical personnel. The measurement of vital signs in hospitals is still predominately carried out manually with traditional contact-based methods, taking over a substantial share of the medical personnel's workload.

Here we present an artificial neural network (ANN)-approach to determine the fractional contributions P from fluorophores to a multi-exponential fluorescence decay in time-resolved lifetime measurements. Conventionally, P are determined by extracting two parameters (amplitude and lifetime) for each underlying mono-exponential decay using non-linear fitting. However, in this case parameter estimation is highly sensitive to initial guesses and weighting.

Real-word data (RWD) refer to data relating to patient health status and/or the delivery of health care routinely collected from a variety of sources, including electronic health records, medical claims data, and patient-generated data. Data sets that combine personal health data stored in different sources can provide a more complete picture of an individual's health and can be used to improve population health through research and practice. The 2-tiered aim of this article is to provide a brief introduction to using RWD in health care research and to present a case study that demonstrates data curation and data merge from different sources while highlighting the benefits and limitations of using RWD.

Objectives: Preliminary evidence has supported the notion that mindful movement-based practices may offer benefits for self-regulation, particularly for vulnerable children. However, this evidence has principally stemmed from subjective assessments of behavioral change, leaving the underlying mechanisms undetermined. The present study aimed to investigate the efficacy of an in-school mindful movement intervention (MMI) for at-risk children within an urban public school for enhancing motor, cognitive, and emotional-behavioral regulation, including control of disruptive and inattentive behaviors characteristic of ADHD.

Biochemical processes are fast and occur on small-length scales, which makes them difficult to measure. Optical nanosensors based on single-wall carbon nanotubes (SWCNTs) are able to capture such dynamics. They fluoresce in the near-infrared (NIR, 850-1700 nm) tissue transparency window and the emission wavelength depends on their chirality.

Activation of T cell responses is essential for effective tumor clearance; however, inducing targeted, potent antigen presentation to stimulate T cell responses remains challenging. We generated Activating Antigen Carriers (AACs) by engineering red blood cells (RBCs) to encapsulate relevant tumor antigens and the adjuvant polyinosinic-polycytidylic acid (poly I:C), for use as a tumor-specific cancer vaccine. The processing method and conditions used to create the AACs promote phosphatidylserine exposure on RBCs and thus harness the natural process of aged RBC clearance to enable targeting of the AACs to endogenous professional antigen presenting cells (APCs) without the use of chemicals or viral vectors.

Mobile integrated health and community paramedicine (MIH-CP) programs are gaining popularity in the United States as a strategy to address the barriers to healthcare access and appropriate utilization. After one year of operation, leadership of Baltimore City's MIH-CP program was interested in understanding the circumstances surrounding readmission for enrolled patients and to incorporate quality improvement tools to direct program development. Retrospective chart review was performed to determine preventable versus unpreventable readmissions with a hypothesis that deficits in social determinants of health would play a more significant role in preventable readmissions.
