Risk of Retinopathy Associated with Long‐Term Use of Hydroxychloroquine in Patients with Rheumatic Diseases: A Systematic Review and Meta‐Analysis

open access: yesArthritis Care &Research, Accepted Article.
Objective We aimed to estimate the prevalence and cumulative incidence of hydroxychloroquine retinopathy (HCQ‐R) and its risk factors among long‐term HCQ users with rheumatic diseases through a systematic review and meta‐analysis of observational studies that used spectral‐domain OCT (SD‐OCT) for screening.

Multivariable stable generalised predictive control

open access: yesIEE Proceedings D Control Theory and Applications, 1993
Summary: Recent work has modified the basic generalized predictive-control strategy so as to derive a predictive-control algorithm with guaranteed closed-loop (nominal) stability for the scalar case. The paper extends this work to the multivariable case.

High Healthcare Utilization Preceding Diagnosis with Juvenile Idiopathic Arthritis

open access: yesArthritis Care &Research, Accepted Article.
Objective Though early diagnosis improves long‐term outcomes, Juvenile Idiopathic Arthritis (JIA) patients often experience prolonged, circuitous paths to diagnosis. To inform diagnostic improvement, we sought to characterize healthcare utilization in the year preceding diagnosis.

Beyond Presumptions: Toward Mechanistic Clarity in Metal‐Free Carbon Catalysts for Electrochemical H2O2 Production via Data Science

open access: yesAdvanced Materials, EarlyView.
Metal‐free carbon catalysts enable the sustainable synthesis of hydrogen peroxide via two‐electron oxygen reduction; however, active site complexity continues to hinder reliable interpretation. This review critiques correlation‐based approaches and highlights the importance of orthogonal experimental designs, standardized catalyst passports ...

PDZK1‐ULK1 Axis Triggers Lipophagy to Inhibit Tumor Progression and Sunitinib Resistance in Clear Cell Renal Cell Carcinoma

open access: yesAdvanced Science, EarlyView.
This study reveals that PDZK1 loss impairs ULK1‐mediated lipophagy, driving lipid droplet accumulation and sunitinib resistance in clear cell renal cell carcinoma. PDZK1 inhibits LEF1 nuclear translocation, enhancing ULK1 transcription. Pharmacological ULK1 activation resensitizes resistant tumors to sunitinib.

Ejecta‐Modulated Bubble Dynamics Play a Dominant Role in Stone Retropulsion

open access: yesAdvanced Science, EarlyView.
Stone motion during laser ablation is shown to result primarily from asymmetric cavitation bubble collapse, not from ejecta recoil. This challenges long‐standing assumptions and highlights the dominant role of bubble dynamics in laser–material interactions.
