Introduction: There is no clear consensus as to what constitutes an obstructive ventilatory impairment (OVI) in pediatric populations.
Aim: To determine the percentage of children/adolescents having an OVI among those addressed for spirometry after taking into account the definitions advanced by some international scholarly societies [British Columbia (BC), British thoracic-society (BTS), Canadian thoracic society (CTS), European respiratory society and American thoracic society (ERS-ATS), global initiative for asthma (GINA), Irish college of general practitioners (ICGP), national asthma council (NAC), national institute of clinical excellence (NICE), Société de pneumologie de langue française, Société pédiatrique de pneumologie et allergologie (SPLF-SP2A), and South African thoracic society (SATS)].
Methods: This bi-centric cross-sectional study involves two medical structures in Sousse/Tunisia, and will encompass children/adolescents aged 6-18 years. A medical questionnaire will be administered, clinical and anthropometric data will be collected, and the spirometric data will be measured by two spirometers. The following six definitions of OVI will be applied: i) GINA: Forced expiratory volume in 1 second (FEV1) < 80% and a FEV1/forced vital capacity (FVC) ≤ 0.90; ii) ICGP: FEV1/FVC < 0.70; iii) ERS-ATS or BTS or SATS or SPLF-SP2A or NAC: FEV1/FVC z-score < -1.645; iv) NICE: FEV1/FVC < 0.70 or FEV1/FVC z-score < -1.645; v) CTS: FEV1/FVC < 0.80 or a FEV1/FVC z-score < -1.645; and vi) ERS: "FEV1 z-score or FEV1/FVC z-score" < -1.645 or "FEV1 or FEV1/FVC" < 0.80.
Expected Results: The percentage of children/adolescents having an OVI will significantly vary between the six definitions.
Conclusion: The frequency of OVI in a pediatric population will depend on the definition chosen.

Background: This study aimed to assess the interobserver variability of semi-automatic diameter and volumetric measurements versus manual diameter measurements for small lung nodules identified on computed tomography scans.
Methods: The radiological patient database was searched for CT thorax examinations with at least one noncalcified solid nodule (∼3-10 mm). Three radiologists with four to six years of experience evaluated each nodule in accordance with the Fleischner Society guidelines using standard diameter measurements, semi-automatic lesion diameter measurements, and volumetric assessments.

Background: We sought to identify predictors of acute renal failure (ARF) following acute type A aortic dissection (ATAAD) and its implications on postoperative outcomes.
Methods: ATAAD cases were identified from The Society of Thoracic Surgeons - Adult Cardiac Surgery Database (2017-2022). Cases with chronic dissection, prior aortic repair, primary endovascular repair, preoperative extracorporeal membrane oxygenation, preoperative renal failure, and operative room deaths were excluded.

Background: The purpose of this study was to report on 2-year results of vertebral body tethering (VBT), performed under a Food and Drug Administration protocol, to obtain insight into outcomes and complications.
Methods: Forty prospectively enrolled patients with adolescent idiopathic scoliosis (AIS) who had a Sanders score of ≤4 or a Risser score of ≤2 underwent VBT for curves between 40° and 70°. Surgical, radiographic, and patient-reported outcomes were reviewed at a minimum 2-year follow-up.

Introduction: In a phase 1 study, bintrafusp alfa was found to have an encouraging clinical activity in patients with previously treated advanced NSCLC. This study evaluated the safety and efficacy of bintrafusp alfa with chemotherapy in patients with stage IV NSCLC regardless of the programmed death-ligand 1 (PD-L1) expression status.
Methods: In this open-label, phase 1b/2 study (NCT03840915), eligible patients were assigned to one of four cohorts.

Atrial fibrillation (AF) remains the most common cardiac arrhythmia worldwide and is associated with significant morbidity and mortality. The European Society of Cardiology (ESC)/European Association for Cardio-Thoracic Surgery (EACTS) have recently released the 2024 guidelines for the management of AF. This review highlights 10 novel aspects of the ESC/EACTS 2024 Guidelines.
