Hemodynamic Significance of APEXCT Coronary Angiography Combined With Dynamic CT Myocardial Perfusion Imaging in Assessing Restenosis After Coronary Stenting

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT This study aimed to evaluate the hemodynamic significance of in‐stent restenosis (ISR) by using a combined anatomical‐functional approach with photon‐counting CT coronary angiography (APEX‐CT CTA) and dynamic CT myocardial perfusion imaging (CT‐MPI). We prospectively enrolled 239 symptomatic patients at least 9 months after PCI.

Immune Clues to Sinus Blues: Linking Biomarkers to Radiologic Score of Rhinosinusitis

open access: yesWorld Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Background Chronic rhinosinusitis (CRS) is a prolonged inflammatory condition of the nasal and paranasal sinuses that significantly affects quality of life. This study examines the relationship between CRS severity (based on Lund‐Mackay [LM] scores), osteitis, and systemic inflammatory markers, including neutrophil‐to‐lymphocyte ratio (NLR ...

Understanding the Type 2 Immunity: An Evolving View Beyond Allergic Diseases

open access: yesAllergy, EarlyView.
ABSTRACT Type 2 (T2) immunity is classically associated with defense against helminths and environmental threats, from a physiological perspective, and with allergies and eosinophilic inflammatory diseases, in a pathological sense. However, growing evidence reveals that T2 pathways also support other essential homeostatic functions, including tissue ...

The Evolution in Understanding the Physiological Causes of Dyspnoea in Large Hiatal Herniation: A Narrative Review

open access: yesANZ Journal of Surgery, EarlyView.
ABSTRACT Background The symptomatology of large hiatus hernia (LHH) has been historically poorly understood, with cardiorespiratory symptoms caused by LHH being underappreciated by clinicians. This study reports on the mechanisms of dyspnoea in LHH through a historical review of symptoms and evolved physiological literature, discussing likely causation.
