Prognosis of incidental lung cancer in lung transplant candidates.

Background: Incidental lung cancer, in the field of lung transplantation (LTx), is more often related to malignancies diagnosed in explants or transplanted organs. Little is known about cancer diagnosed during the medical evaluation of potential LTx candidates. What are the clinical, and prognostic differences between lung cancers diagnosed before or after transplantation in LTx candidates?

Methods: We performed a retrospective, observational, single-center study to describe the characteristics of lung malignancies first discovered during the pre-transplant assessment and then identified in lung explants, over the same period.

Brain microstructural damage through serial diffusion tensor imaging and outcomes in Susac syndrome: A prospective cohort study.

Background: Susac syndrome (SuS) is a rare immune-mediated microangiopathy with potential disabling evolution. We aimed to analyze brain microstructural damage through diffusion tensor imaging (DTI) in SuS and determine its association with poor outcomes.

Method: CarESS study is a prospective multicenter national cohort study of patients with SuS.

Clinical and radiological pattern of olaparib-induced interstitial lung disease.

Background: PARP inhibitors (PARPi) are used in the treatment of ovarian, breast, pancreatic, and prostate cancers. Pneumonitis has been identified as a potential side effect, with a higher meta-analysis-assessed risk for olaparib versus other PARPi. Olaparib-induced interstitial lung disease (O-ILD) was first described within the Japanese population, with few information available for Caucasian patients.

Size-matching in lung transplantation by computed tomography for end-stage interstitial disease: a retrospective analysis.

Background: Size matching between donors and recipients is a major issue in lung transplantation (LTx), especially in patients with restrictive lung disease (RLD). This study aims to evaluate computed tomography (CT) as an additional method for defining the total lung capacity (TLC) in patients with end-stage interstitial disease awaiting LTx.

Methods: Clinical data and CT scans from patients who underwent a first LTx from January 2014 to July 2018 in Bichat Hospital, Paris, were prospectively included in a database.

A YAP-centered mechanotransduction loop drives collective breast cancer cell invasion.

Dense and aligned Collagen I fibers are associated with collective cancer invasion led by protrusive tumor cells, leader cells. In some breast tumors, a population of cancer cells (basal-like cells) maintain several epithelial characteristics and express the myoepithelial/basal cell marker Keratin 14 (K14). Emergence of leader cells and K14 expression are regarded as interconnected events triggered by Collagen I, however the underlying mechanisms remain unknown.

Clinical characteristics and outcomes of respiratory syncytial virus-associated ARF in immunocompetent patients: A seven-year experience at a tertiary hospital in France.

Background: Respiratory syncytial virus (RSV) is widely recognized as a cause of acute respiratory failure in infants and immunocompromised patients. However, RSV can also contribute to acute respiratory failure in adults, particularly among the elderly population. The objective of this study was to analyze the clinical characteristics and outcomes of immunocompetent adults hospitalized for RSV infection.

The extracellular matrix as hallmark of cancer and metastasis: From biomechanics to therapeutic targets.

The extracellular matrix (ECM) is essential for cell support during homeostasis and plays a critical role in cancer. Although research often concentrates on the tumor's cellular aspect, attention is growing for the importance of the cancer-associated ECM. Biochemical and physical ECM signals affect tumor formation, invasion, metastasis, and therapy resistance.

Hemoptysis: From Diagnosis to Treatment.

Management of hemoptysis begins with an angio-CT to identify the location, the bleeding vessel, mapping of systemic arteries and the cause of the hemoptysis. Endovascular treatment is the first-line therapy, in 90% of cases by embolization of the systemic arteries and in 10% of cases by occlusion of the pulmonary arteries.

Splenic Artery Infectious Aneurysms in Infective Endocarditis - An Observational Study and Comprehensive Literature Review.

Background: To determine the prevalence, the clinical and radiological features, associated factors, treatment, and outcome of splenic artery aneurysms (SAAs) in infective endocarditis (IE).

Methods: We retrospectively reviewed 474 consecutive patients admitted to our institution with definite IE (2005-2020).

Results: Six patients had SAAs (1.

Detection and quantification of pulmonary embolism with artificial intelligence: The SFR 2022 artificial intelligence data challenge.

Purpose: In 2022, the French Society of Radiology together with the French Society of Thoracic Imaging and CentraleSupelec organized their 13th data challenge. The aim was to aid in the diagnosis of pulmonary embolism, by identifying the presence of pulmonary embolism and by estimating the ratio between right and left ventricular (RV/LV) diameters, and an arterial obstruction index (Qanadli's score) using artificial intelligence.

Materials And Methods: The data challenge was composed of three tasks: the detection of pulmonary embolism, the RV/LV diameter ratio, and Qanadli's score.

Strategies to safely rule out pulmonary embolism in COVID-19 outpatients: a multicenter retrospective study.

Objectives: The objective was to define a safe strategy to exclude pulmonary embolism (PE) in COVID-19 outpatients, without performing CT pulmonary angiogram (CTPA).

Methods: COVID-19 outpatients from 15 university hospitals who underwent a CTPA were retrospectively evaluated. D-Dimers, variables of the revised Geneva and Wells scores, as well as laboratory findings and clinical characteristics related to COVID-19 pneumonia, were collected.

Multimodal Techniques to Study Tumor Growth, Basement Membrane Breaching, and Invasion in 3D Matrices.

Cancer-derived organoids and three-dimensional (3D) extracellular matrix (ECM) are taking center stage as in vitro models to study neoplastic cell behavior, since they recapitulate the heterogeneous cellular composition of tumors and their extracellular environment. In combination with imaging and molecular/biochemical techniques, 3D organoid models have contributed substantially to our knowledge about the cellular and molecular mechanisms that regulate the growth of tumors and invasion into the surrounding tissue. We here outline a set of protocols that describe culturing of cancer-derived organoids in 3D matrices and various strategies that allow modeling of tumor growth, tumor cell penetration into basement membranes, and invasion into Collagen I-rich ECM.

Breast metastasis of a lung carcinoma.

Breast metastasis is a rare phenomenon (0.2-1.3%) compared to primary breast lesions.

Grade 3-4 Immune-Related Adverse Events Induced by Immune Checkpoint Inhibitors in Non-Small-Cell Lung Cancer (NSCLC) Patients Are Correlated with Better Outcome: A Real-Life Observational Study.

Background: Immune checkpoint inhibitors (ICIs) have been a major advance in treating non-small-cell lung cancer (NSCLC). Programmed cell death protein-1/programmed death-ligand 1 blockade enhances immune function, mediating anti-tumor activity, yet causing immune-related adverse events (irAEs). We investigated the prognostic role of Grade 3−4 irAEs on overall survival (OS).

Clinical assessment of scannographic markers for sarcopenia in lung transplant candidates.

Introduction: The selection of patients for lung transplantation is difficult. An aspect of the patient's general condition and frailty can be assessed by measuring the surface area of certain muscles on CT. Indeed, sarcopenia, assessed by measuring the area of psoas muscles on scannographic sections has already been shown to be associated with poor outcomes in lung transplant and other major surgeries and could thus be helpful to evaluate candidates to lung transplant.

Effect of diagnosis level of certainty on adherence to antibiotics' guidelines in ED patients with pneumonia: a post-hoc analysis of an interventional trial.

Background And Importance: Clinical diagnosis of community-acquired pneumonia (CAP) is difficult to establish with certainty. Adherence to antibiotic guidelines independently affects the prognosis of CAP patients.

Objective: We aimed to determine whether guidelines' adherence was related to CAP diagnosis level of certainty and could be reinforced accordingly to diagnosis improvement.

CT features of community-acquired pneumonia at the emergency department.

Background: Chest computed tomography (CT) was reported to improve the diagnosis of community-acquired pneumonia (CAP) as compared to chest X-ray (CXR). The aim of this study is to describe the CT-patterns of CAP in a large population visiting the emergency department and to see if some of them are more frequently missed on CXR.

Materials And Methods: This is an ancillary analysis of the prospective multicenter ESCAPED study including 319 patients.

Spatial collagen stiffening promotes collective breast cancer cell invasion by reinforcing extracellular matrix alignment.

The tumor micro-environment often contains stiff and irregular-bundled collagen fibers that are used by tumor cells to disseminate. It is still unclear how and to what extent, extracellular matrix (ECM) stiffness versus ECM bundle size and alignment dictate cancer cell invasion. Here, we have uncoupled Collagen-I bundling from stiffness by introducing inter-collagen crosslinks, combined with temperature induced aggregation of collagen bundling.
