Diagnostic Accuracy of Cardiovascular Disease Prediction Models: A Systematic Review and Meta‐Analysis of Validation Studies

open access: yesHealth Science Reports, Volume 9, Issue 5, May 2026.
ABSTRACT Background and Aim Cardiovascular diseases (CVD) are widely accepted to be the most serious health care problem in the world. We performed a diagnostic test accuracy systematic review and meta‐analysis to establish the real‐world performance of established CVD risk prediction tools, providing high‐certainty evidence to optimize primary ...

Clinical validation of a high‐definition mid‐position magnetic resonance imaging approach for lung radiotherapy planning

open access: yesMedical Physics, Volume 53, Issue 5, May 2026.
Abstract Background Respiratory‐correlated four‐dimensional (4D) magnetic resonance imaging (4D‐MRI) is useful to estimate breathing induced motion for MRI‐guided radiotherapy. Based on 4D‐MR image sets, a three‐dimensional mid‐position (MidP) MRI can be generated using deformable image registration (DIR) for radiotherapy planning. However, the desired

Effective Removal of Fe and Ca From Coal Fly Ash for High‐Purity and High‐Surface‐Area Zeolite X Synthesis: A Comparative Study of Acid Refluxing and Acid Roasting Methods

open access: yesChemistryOpen, Volume 15, Issue 5, May 2026.
Coal fly ash (CFA) is an abundant industrial waste rich in silica and alumina and represents a viable feedstock for zeolite synthesis; however, high levels of calcium and iron limit zeolite purity and crystallisation. This study evaluates acid refluxing and acid roasting as pre‐treatment strategies for the simultaneous removal of Ca and Fe from high ...

Synergistic Photophysical and Mechanical Enhancement in Europium Supramolecular Hydrogel by Incorporating Gd(DPA)3 Complex (DPA = Dipicolinate)

open access: yesChemistryOpen, Volume 15, Issue 5, May 2026.
Lanthanide‐based hydrogels incorporating Ln(DPA)3 complexes are synthesized and exhibit enhanced mechanical and luminescent properties. Increased complex concentration improves stiffness and emission intensity without altering coordination symmetry. Computational insights reveal preserved structural features, while lifetime changes highlight hydrogel ...
