Test-retest reliability of cardiopulmonary exercise test-derived metrics in individuals with COPD versus healthy controls.
Clin Physiol Funct Imaging
January 2025
Centre for Physical Activity Research, Copenhagen University Hospital - Rigshospitalet, Copenhagen, Denmark.
Background: Cardiopulmonary exercise testing (CPET) is usually considered the gold standard for assessing maximal oxygen consumption (V̇O), a health and performance marker in patients with chronic obstructive pulmonary disease (COPD). Despite the widespread application of CPET, the absolute and relative test-retest reliability of CPET-derived metrics remains unexamined.
Objective: To examine and compare test-retest reliability of CPET derived metrics in individuals with COPD and healthy matched controls.
Magnetic Resonance imaging evaluation of the distance to the popliteal artery in arthroscopic popliteus tendon versus posterior cruciate ligament reconstruction.
J Orthop
August 2025
Department of Orthopaedic Surgery, Antwerp University Hospital, 2650, Edegem, Belgium.
Purpose: Wide acceptance of arthroscopically treating posterolateral corner injuries has not occurred. There remains a fear of neurovascular (NV) injury while arthroscopically performing these reconstructions. The study's aim is to compare on Magnetic Resonance Scans the distance of the tibial tunnel in an arthroscopic popliteus tendon reconstruction (APB) and arthroscopic posterior cruciate ligament (PCL) reconstruction (APC) to the popliteal neurosvascular bundle.

Children (Basel)
January 2025
Department of Dentistry, Faculty of Medicine and Pharmacy, University of Oradea, 10 Piața 1 Decembrie Street, 410073 Oradea, Romania.
Background/objectives: Dental age estimation plays a critical role in pediatric dentistry, orthodontics, and forensic medicine. The Nolla method, widely applied globally, has shown variable accuracy across different populations. This study aimed to evaluate the applicability and accuracy of the Nolla method in estimating the dental age of Romanian children and to identify potential discrepancies between dental and chronological ages.

Diagnostics (Basel)
January 2025
Niculae Stancioiu Heart Institute, Calea Motilor 19-21, 400001 Cluj-Napoca, Romania.
Mediastinal tumors, regardless of their location, can grow to significant sizes, causing compression-related symptoms. The term "giant" mediastinal tumor is inconsistently defined in the literature. This study presents a new clinical-radiological classification (CRC) for mediastinal tumors and evaluates its applicability through a systematic review and a detailed case analysis of a giant thymolipoma.

Breath-hold T2-weighted half-Fourier acquisition single-shot turbo spin echo (HASTE) magnetic resonance imaging (MRI) of the upper abdomen with a slice thickness below 5 mm suffers from high image noise and blurring. The purpose of this prospective study was to improve image quality and accelerate imaging acquisition by using single-breath-hold T2-weighted HASTE with deep learning (DL) reconstruction (DL-HASTE) with a 3 mm slice thickness. MRI of the upper abdomen with DL-HASTE was performed in 35 participants (5 healthy volunteers and 30 patients) at 3 Tesla.
