A Novel Method for Generating a Fused Ventilation–Perfusion Map Using CT‐Derived Ventilation and FDG‐PET for Lung Functional Avoidance in Radiotherapy: A Feasibility Study

Precision Radiation Oncology, EarlyView.
This study retrospectively analyzed two types of respiratory phase CT and PET/CT images of 20 lung cancer patients. After DIR and functional grading, three lung function images were developed, and their correlations and differences were evaluated. Abstract Background Pulmonary ventilation–perfusion function plays a crucial role in both radiotherapy ...

Sleep assessment using accelerometry: Not all algorithms are equal

Sleep Research, EarlyView.
Abstract Study objectives Accelerometry devices are increasingly used to assess sleep. However, whether different algorithms provide consistent estimates remains uncertain. This study compared sleep parameters derived from two accelerometry‐based algorithms and a self‐reported sleep journal.

Pediatric Versus Adult Shear‐Induced Hemolysis—Are Age‐Related Blood Properties the Main Cause for Differences?

Artificial Organs, EarlyView.
Graphical summary of the experimental comparison of shear‐induced hemolysis in pediatric and adult blood using a Couette shearing device. Pediatric blood shows a trend toward lower increase in hemolysis at higher shear stress amplitudes, while no relevant differences are observed at low and intermediate stresses.

Characterising PRPF31‐associated retinal dystrophy: Clinical insights from baseline data in a natural history study

Acta Ophthalmologica, EarlyView.
Abstract Purpose To characterise the baseline clinical features and genotypes of adults with pre‐mRNA processing factor 31 (PRPF31)‐associated retinal dystrophy (RD) enrolled in a prospective, multicentre 4‐year natural history study, and to explore correlations between selected baseline parameters.

Mesopic microperimetry in Stargardt disease: Application and reliability

Acta Ophthalmologica, EarlyView.
Abstract Purpose Mesopic microperimetry (mMP) is a promising functional endpoint in clinical trials for Stargardt disease type 1 (STGD1). This study evaluated the test–retest variability of mMP and influencing factors, which is essential for ensuring reliability in future STGD1 trials.

Sample size determination for hypothesis testing on the intraclass correlation coefficient in a two‐way analysis of variance model

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Reliability evaluation is critical in fields such as psychology and medicine to ensure accurate diagnosis and effective treatment management. When participants are evaluated by the same raters, a two‐way ANOVA model is suitable to model the data, with the intraclass correlation coefficient (ICC) serving as the reliability metric.

Early detection of type 2 diabetes mellitus‐associated cognitive dysfunction: The potential of amide proton transfer‐weighted imaging

Diabetes, Obesity and Metabolism, EarlyView.
Abstract Aims Type 2 diabetes mellitus (T2DM) may lead to diabetes‐associated cognitive dysfunction (DACD). We aimed to develop an amide proton transfer‐weighted (APTw) magnetic resonance imaging (MRI) biomarker to assist early identification of T2DM with DACD. Materials and Methods The study included 27 T2DM patients, comprising 19 with mild cognitive

Agreement of the performance of equine electrocardiogram recording devices for ECG complexity analysis

Equine Veterinary Journal, EarlyView.
Abstract Background Non‐linear equine electrocardiography (ECG) analysis is an actively developing study area which has the potential to lead to novel, artificial intelligence‐based diagnostic tools in equine cardiology. As more ECG recording devices are becoming available, there is a need to ensure results are interchangeable regardless of the ...
