VQ‐Wave: A Physics‐Driven Spatiotemporal Deep Learning Approach for Noncontrast‐Enhanced Lung Ventilation and Perfusion MRI

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop a robust deep learning framework for noncontrast‐enhanced functional lung MRI, overcoming the limitations of spectral decomposition in the presence of physiological nonstationarity. Methods We introduce VQ‐Wave (Ventilation/Q‐perfusion Waveform‐based Assessment of Variable Evolutions), a physics‐driven spatiotemporal ...

Ventilation Imaging of the Lung at 0.55T With Continuous Slice Cycling

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To propose and evaluate a novel method for pulmonary ventilation imaging, offering considerably improved SNR. Methods A continuous slice cycling (CSC) acquisition scheme is proposed to exclusively capture signal modulations from respiratory motion with increased SNR.

Unplanned Post‐Operative Pediatric Intensive Care Unit Admissions After Elective Upper Airway Procedures: A Retrospective Case–Control Study

open access: yesPediatric Anesthesia, EarlyView.
ABSTRACT Background Elective pediatric upper airway procedures are generally safe; however, some patients require unplanned pediatric intensive care unit admission, increasing care complexity. Aims To identify perioperative risk factors associated with unplanned pediatric intensive care unit admission following elective pediatric upper airway surgery ...

Endoplasmic reticulum stress and the unfolded protein response in lung diseases: molecular pathways and therapeutic interventions

open access: yesThe Journal of Pathology, EarlyView.
Abstract Endoplasmic reticulum stress (ERS) occurs when the protein‐folding capacity of the endoplasmic reticulum (ER) is overwhelmed, triggering the unfolded protein response (UPR) to restore homeostasis. However, severe or persistent ERS can shift the UPR toward pro‐inflammatory, apoptotic, and fibrotic signaling, thereby exacerbating tissue injury ...

Evidence‐based guideline for clinical practice in the diagnosis, treatment, management, and prevention of recurrent wheezing in infants and toddlers in China

open access: yesPediatric Investigation, EarlyView.
ABSTRACT Wheezing is a common respiratory symptom in infants and toddlers, and recurrent wheezing is a significant respiratory disorder affecting this age group. Given the multifactorial etiology of recurrent wheezing, clinical practice lacks standardized diagnostic and therapeutic protocols. Recent years have witnessed substantial progress in clinical
