Efficacy of Various Dry Electrode-Based ECG Sensors: A Review.

Long-term electrocardiogram (ECG) monitoring is crucial for detecting and diagnosing cardiovascular diseases (CVDs). Monitoring cardiac health and activities using efficient, noninvasive, and cost-effective techniques such as ECG can be vital for the early detection of different CVDs. Wet electrode-based traditional ECG techniques come with unavoidable limitations of the altered quality of ECG signals caused by gel volatilization and unwanted noise followed by dermatitis.

Bulk-like structural, magnetic and optical properties of (111)- and (001)-NiO thin films.

We have grown (111)- and (001)-oriented NiO thin films on (0001)-Sapphire and (001)-MgO substrates using pulsed laser deposition (PLD), respectively. DC magnetic susceptibility measurements underline that the Néel temperatures of the samples are beyond room-temperature. This is further confirmed by the presence of two-magnon Raman scattering modes in these films in ambient conditions.

Rationale and Design of the Personalized Therapy Study: Evaluating Real-World Performance of Two Automated Defibrillation Therapy Algorithms.

Background: Barriers to maximizing patient benefit with implantable defibrillation devices include limited ability to tailor antitachycardia pacing (ATP) therapy in real-time and identify patients at risk of heart failure (HF) events early on. The Personalized Therapy study aims to evaluate the performance of two algorithms, intrinsic ATP (iATP) and TriageHF, to address these barriers in routine clinical practice.

Methods And Results: The Personalized Therapy Study was designed as a prospective, multicenter, post-market registry study expected to enroll approximately 2,200 patients meeting the following criteria: (1) implanted with a study-eligible device regardless of procedure type; (2) Medtronic CareLink® Network enrolled; (3) TriageHF enabled within CareLink and High Risk Alert notifications turned ON; and (4) iATP enabled.

Navigating the complexities of perianal Crohn's disease: Diagnostic strategies, treatment approaches, and future perspectives.

This article discusses the literature review article by Pacheco published in July 2024; the authors provided good reviews of perianal Crohn's disease (CD), and challenges faced by clinicians in the management. CD, characterized by its chronic and relapsing nature, is an idiopathic condition that can involve any segment of the gastrointestinal tract. Perianal disease impacts up to 40% of patients with CD, with perianal fistulas constituting up to 80% of perianal lesions.

Spin-Selective Charge Transfer-SERS Driven Label-Free Enantioselective Discrimination of Chiral Molecules on Ag Nanoparticle-Decorated Ni Nanorod Arrays.

Enantioselective discrimination is critical in several fields, particularly in pharmaceutics and clinical drug research. Chiral molecules possess unique charge transfer properties, showing an enantioselective preference for electron spin orientation when interacting with the magnetic surface. Here, we developed spin-selective charge transfer (SSCT)-based label-free surface-enhanced Raman scattering (SERS) achiral magnetic substrates for the enantioselective discrimination of chiral molecules without creating asymmetric chiral adsorption sites.

Impact of a universal monitoring system ("third party") on outcomes of ICD patients: A nationwide study.

Background: Adherence to recommended follow-up schedules for remote monitoring (RM) of patients with implantable cardioverter-defibrillators (ICDs) is inconsistent, which may influence clinical outcomes. Systematic organization through a "third-party" universal monitoring system (UMS) may be beneficial.

Objective: We aimed to evaluate the clinical impact of RM and any incremental benefit of UMS vs conventional RM.

India's role in the odyssey of medical training in South Africa.

Apartheid had a devastating impact on medical education in South Africa. Until the development of the University of Natal Medical School in 1951, there were minimal opportunities for blacks (collectively Africans, Indians and so-called coloureds) to undertake undergraduate and postgraduate medical training in South Africa. At the height of apartheid (1968-1977), whites who had constituted 17% of the population, accounted for up to 87% of all medical graduates.

Anisotropic membrane with high proton conductivity sustaining upon dehydration.

In fuel cells and electrolyzers, suboptimal proton conductivity and its dramatic drop at low humidity remain major drawbacks in proton exchange membranes (PEMs), including current benchmark Nafion. Sustained through-plane (TP) alignment of nanochannels was proposed as a remedy but proved challenging. We report an anisotropic composite PEM, mimicking the water-conductive composite structure of bamboo that meets this challenge.

Non-osseous coalition of accessory anterolateral talar facet-A case series.

The accessory anterolateral talar facet (AALTF) is an anatomical variation that broadens the apex of the lateral talar process. Studies have associated it with other tarsal coalitions as a cause of rigid painful flatfoot. However, a coalition of an AALTF has never been described before.

Anisotropic Stick-Slip Frictional Surfaces via Titania Nanorod Patterning.

Nanoscale or microscale surface texturing is an effective technique to tailor the tribological properties between two surfaces that are rubbed against each other. In order to achieve the desired frictional properties by a patterned surface, one needs an in-depth understanding of the underlying mechanisms. Here, we demonstrate anisotropic stick-slip friction achieved via a nanotextured surface of tilted titania nanorods (TiNRs).

Magnetic resonance imaging evaluation of gynecological mass lesions: A comprehensive analysis with histopathological correlation.

Evaluating gynecological mass lesions and reviewing their morphological characteristics based on their imaging appearance on magnetic resonance imaging (MRI), and correlating the MRI findings with histopathological findings, was the central theme of our study. This observational cross-sectional study was conducted on 60 female patients with clinically suspected gynecological mass lesions upon physical examination and/or ultrasonography, referred for MRI at a tertiary care hospital over a 1-year period between June 2022 and July 2023. A broad spectrum of differential diagnoses of gynecological masses was observed.

Cholera disease dynamics with vaccination control using delay differential equation.

The COVID-19 pandemic came with many setbacks, be it to a country's economy or the global missions of organizations like WHO, UNICEF or GTFCC. One of the setbacks is the rise in cholera cases in developing countries due to the lack of cholera vaccination. This model suggested a solution by introducing another public intervention, such as adding Chlorine to water bodies and vaccination.

Evolution and prognosis of tricuspid and mitral regurgitation following cardiac implantable electronic devices: a systematic review and meta-analysis.

Aims: Significant changes in tricuspid regurgitation (TR) and mitral regurgitation (MR) post-cardiac implantable electronic devices (CIEDs) are increasingly recognized. However, uncertainty remains as to whether the risk of CIED-associated TR and MR differs with right ventricular pacing (RVP) via CIED with trans-tricuspid RV leads, compared with cardiac resynchronization therapy (CRT), conduction system pacing (CSP), and leadless pacing (LP). The study aims to synthesize extant data on risk and prognosis of significant post-CIED TR and MR across pacing strategies.
