Purpose: To evaluate the repeatability and reproducibility of the Dr.Noon CVD, an artificial intelligence software as a medical device that assesses cardiovascular risk from retinal photographs by providing risk scores and classifying patients into three categories: category 0 (low risk), category 1 (intermediate risk), and category 2 (high risk).
Methods: In this prospective, single-center study, participants underwent nonmydriatic fundus photography. For repeatability assessment, one examiner captured 3 consecutive images per eye. For reproducibility, a second examiner independently acquired 1 image per eye. Intraclass correlation coefficients (ICCs), within-subject standard deviations, and coefficients of variation were calculated. Differences by risk category and lens status were assessed using ANOVA and independent t tests.
Results: Overall, Dr.Noon CVD demonstrated excellent reliability, with a repeatability ICC of 0.997 (95% confidence interval [CI]: 0.996-0.998) and a reproducibility ICC of 0.999 (95% CI: 0.998-0.999). When analyzed by risk categories, repeatability, and reproducibility ICCs were 0.985 (95% CI: 0.974-0.997) and 0.995 (95% CI: 0.990-0.997) for category 0, 0.960 (95% CI: 0.918-0.983) and 0.969 (95% CI: 0.921-0.988) for category 1, and 0.965 (95% CI: 0.943-0.980) and 0.984 (95% CI: 0.971-0.992) for category 2. In terms of lens status, phakic eyes showed repeatability and reproducibility ICCs of 0.998 (95% CI: 0.996-0.998) and 0.999 (95% CI: 0.998-0.999), respectively, while pseudophakic eyes showed slightly lower but still excellent values of 0.989 (95% CI: 0.980-0.995) and 0.994 (95% CI: 0.988-0.997).
Conclusions: Dr.Noon CVD demonstrated high precision with excellent repeatability and reproducibility across all risk levels and lens statuses, supporting its reliability for cardiovascular risk screening using retinal images.

Purpose: Melbourne rapid fields (MRF) online perimetry is web-based software that allows white-on-white threshold perimetry using any computer. This study assesses the perimetric outcomes of MRF10-2 protocol via laptop computer in comparison to Humphrey field analyzer (HFA).
Methods: This prospective and cross-sectional study included 91 eyes from 91 Japanese glaucoma patients.

The rate of sudden unexpected death in epilepsy (SUDEP) is ~1 per 1000 patients each year. Terminal events reportedly involve repeated and prolonged apnea, suggesting a failure to autoresuscitate. To better understand the mechanisms and identify novel therapeutics, standardized tests to screen for autoresuscitation efficacy are needed in preclinical SUDEP.

Electrochemical sensors capable of detecting different types of biomolecules using a single electrode are highly desirable for simplifying analytical platforms and expanding their practical applicability. Herein, we develop a multifunctional electrochemical sensor based on a 3D honeycomb-like porous rGO/PPy-POM composite film for the independent detection of dopamine (DA) and folic acid (FA), two chemically distinct and clinically relevant biomolecules. The electrode is fabricated through a facile, low-cost, and environmentally friendly breath figure method to create a 3D porous reduced graphene oxide (rGO) framework, followed by codeposition of polypyrrole (PPy) and polyoxometalates (POMs).

Background: Fermented foods vary significantly by food substrate and regional consumption patterns. Although they are consumed worldwide, their intake and potential health benefits remain understudied. Europe, in particular, lacks specific consumption recommendations for most fermented foods.

An early diagnosis of Parkinson's disease (PD) represents a challenge and novel accurate biomarkers are therefore urgently needed. Detection of phosphorylated α-synuclein (p-α-syn) in skin nerve fibers has shown promise as such a marker. However, its accuracy for the identification of PD among patients with early signs of parkinsonism has not been thoroughly explored.
