A Two‐Stage Questionnaire and Actigraphy Screening for iRBD in a Multicenter Retrospective Cohort

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Isolated rapid‐eye‐movement sleep behavior disorder is a prodromal marker of synucleinopathies. However, most cases remain undiagnosed due to the insufficient predictive value of questionnaires and limited access to confirmatory video‐polysomnography. We assessed a two‐stage screening strategy combining a brief questionnaire on rapid‐

Effectiveness of Fractional Flow Reserve and Resting Full-Cycle Ratio In Arteries with Tandem Stenosis

Journal of Biomechanics
Coronary artery disease, associated with significant mortality and morbidity, is caused by atherosclerotic stenoses (blood vessel cholesterol blockages) obstructing coronary blood flow. Stenoses may be widespread, with several occurring in one coronary artery.

Rheumatoid Arthritis and Coronary Artery Calcium Progression: A Case Cohort Analysis From ELSA‐Brasil

Arthritis Care &Research, EarlyView.
Objective To investigate the association between rheumatoid arthritis (RA) and coronary artery calcium (CAC) prevalence, incidence, and progression over four years in adults without prior cardiovascular disease. Methods A case‐cohort study within the Brazilian Longitudinal Study of Adult Health (ELSA‐Brasil) included 585 participants (86 patients with ...

Discordance predictor between fractional flow reserve and resting full-cycle ratio in clinical characteristics

European Heart Journal, 2020
Abstract Introduction Fractional flow reserve (FFR) is a gold standard method to evaluate functional lesion severity in daily clinical practice. Recently, the resting full-cycle ratio (RFR) which was newly developed resting indices was launched.

Patients improve, patterns persist: longitudinal stability of RA joint involvement patterns

Arthritis Care &Research, Accepted Article.
Objective Rheumatoid arthritis is a heterogeneous disease. Data‐driven approaches, from synovial histology to joint involvement patterns (JIPs), have sought to define clinically meaningful subgroups. Whether these subgroups represent stable phenotypes or transient disease states remains unclear.

Diagnostic Performance of Non‐Hyperemic Pressure Ratios Versus Fractional Flow Reserve Stratified by Coronary Artery: A Systematic Review and Meta‐Analysis of Individual Patient Data

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background In the assessment of coronary physiology, non‐hyperemic pressure ratios (NHPRs) provide an alternative to fractional flow reserve (FFR) without the need for hyperemic agents, reducing procedural time, side effects, and costs.

P5621Diagnostic accuracy of resting full-cycle ratio in the non-culprit artery of acute patients

European Heart Journal, 2019
Abstract Introduction Resting full-cycle ratio (RFR) is a novel non-hyperemic index of coronary stenosis severity, independent of the timing within the cardiac cycle. Recent data has demonstrated good correlation between RFR and Fractional Flow Reserve (FFR) in stable coronary disease (SCD).

Distinct Microstructural Characteristic Lengths Defining Notch Fatigue Crack Initiation and Propagation, and Defect Tolerance in Advanced Steels

Advanced Engineering Materials, EarlyView.
Schematic representation of modes of microcrack nucleation, growth and temporary arrestment at different boundaries, with the criteria for crack propagation in three scenarios: (1) large notch, (2) defect/small sharp notch, and (3) long crack. This work revisits and integrates results on the fatigue behavior of advanced bainitic steels (in particular ...

6115Influence of microvascular function and coronary flow in the diagnostic precision of resting full-cycle ratio

European Heart Journal, 2019
Abstract Introduction Resting full-cycle ratio (RFR) has been recently described as a non-hyperemic index of coronary stenosis with good concordance with Fractional Flow Reserve (FFR). However, there is no information concerning the influence of microvascular function and coronary flow on RFR results.

3D‐Printed Titanium Gyroid Scaffold Structure Integrated With Tough Hybrid Materials for Cartilage Replacement

Advanced Engineering Materials, EarlyView.
This study proposes a potential device design for joint cartilage replacement. Silica‐polytetrahydrofuran (SiO2‐PolyTHF) hybrids with customizable mechanical properties were developed to mimic the characteristics of a natural meniscus. These were synthesized through a two‐pot sol–gel hybrid process.
