Muscle strength, quantity and quality and muscle fat quantity and their association with oxidative stress in patients with facioscapulohumeral muscular dystrophy: Effect of antioxidant supplementation.

The purpose of this study was to identify causes of quadriceps muscle weakness in facioscapulohumeral muscular dystrophy (FSHD). To this aim, we evaluated quadriceps muscle and fat volumes by magnetic resonance imaging and their relationships with muscle strength and oxidative stress markers in adult patients with FSHD (n = 32) and healthy controls (n = 7), and the effect of antioxidant supplementation in 20 of the 32 patients with FSHD (n = 10 supplementation and n = 10 placebo) (NCT01596803). Compared with healthy controls, the dominant quadriceps strength and quality (muscle strength per unit of muscle volume) were decreased in patients with FSHD.

Brief Report: A Multidisciplinary Initial Workup for Suspected Lung Cancer as Fast-Track Intervention to Histopathologic Diagnosis.

Guidelines for optimal timing of lung cancer diagnosis and treatment have been implemented in many countries, but the effect of fast-track interventions on the shortening of time interval is still debatable. In this study, the delay from the first specialist visit to the histopathologic diagnosis was compared between two patient cohorts: before (n = 280) and after (n = 247) implementation of a fast-track multidisciplinary diagnosis program. The cumulative incidence function curves were compared, and hazard ratio was adjusted in the Cox model.

Safety, Efficacy and Mid-Term Outcome for Transarterial Embolization (TAE) of Renal Angiomyolipoma (AML) Using Ethylene Vinyl Alcohol Copolymer Liquid Embolic Agent (EVOH).

Transarterial embolization (TAE) of renal angiomyolipoma (AML) is effective in treating and preventing hemorrhage. We report our experience using EVOH with a single-center retrospective study of all AML embolized with EVOH between June 2013 and March 2022 at the Montpellier University Hospital. A total of 29 embolizations were carried out in 24 consecutive patients (mean age: 53.

Nutritional Status of Patients with Facioscapulohumeral Muscular Dystrophy.

In patients with facioscapulohumeral muscular dystrophy (FSHD), a rare genetic neuromuscular disease, reduced physical performance is associated with lower blood levels of vitamin C, zinc, selenium, and increased oxidative stress markers. Supplementation of vitamin C, vitamin E, zinc, and selenium improves the quadriceps' physical performance. Here, we compared the nutritional status of 74 women and 85 men with FSHD.

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.

Obesity in women with asthma: Baseline disadvantage plus greater small-airway responsiveness.

Background: Obesity is known to diminish lung volumes and worsen asthma. However, mechanistic understanding is lacking, especially as concerns small-airway responsiveness. The objective of this study was therefore to compare small-airway responsiveness, as represented by the change in expiratory:inspiratory mean lung density ratios (MLD , as determined by computed tomography [CT]) throughout methacholine testing in obese versus non-obese women with asthma.

Feasibility of Endovascular Recanalization in Post-Thrombotic Syndrome of Intentionally Interrupted Inferior Vena Cava.

Purpose: Surgical plication of inferior vena cava was commonly used until the 1980s for prevention of pulmonary embolism, associated with high incidence of post-thrombotic syndrome (PTS). This study aims to assess the feasibility and safety of endovascular iliocaval recanalization after intentionally surgically interrupted inferior vena cava by external plicating clip.

Materials And Methods: Endovascular iliocaval recanalizations in relation to previous vena cava clip plication were extracted from the retrospective French multicentre database and further analysed.

Complication and lung function impairment prediction using perfusion and computed tomography air trapping (CLIPPCAIR): protocol for the development and validation of a novel multivariable model for the prediction of post-resection lung function.

Background: Recent advancements in computed tomography (CT) scanning and post processing have provided new means of assessing factors affecting respiratory function. For lung cancer patients requiring resection, and especially those with respiratory comorbidities such as chronic obstructive pulmonary disease (COPD), the ability to predict post-operative lung function is a crucial step in the lung cancer operability assessment. The primary objective of the CLIPPCAIR study is to use novel CT data to develop and validate an algorithm for the prediction of lung function remaining after pneumectomy/lobectomy.

Long-Term Imaging Follow-Up in DIPNECH: Multicenter Experience.

Diffuse pulmonary neuroendocrine cell hyperplasia (DIPNECH) is a rare pre-invasive disease whose pathophysiology remains unclear. We aimed to assess long-term evolution in imaging of DIPNECH, in order to propose follow-up recommendations. Patients with histologically confirmed DIPNECH from four centers, evaluated between 2001 and 2020, were enrolled if they had at least two available chest computed tomography (CT) exams performed at least 24 months apart.

Differentiating between active and latent tuberculosis with chest computed tomography.

Purpose: The purpose of this study was to evaluate the capabilities of chest computed tomography (CT) in distinguishing between active and latent tuberculosis in patients positive for interferon-gamma release assay (IGRA) testing, and to compare the performance of CT with that of quantitative IGRA testing in a low incidence setting.

Materials And Methods: Patients with latent or active tuberculosis define by an IGRA positive test were retrospectively recruited. Sensitivity, specificity and accuracy were determined for CT variables and quantitative IGRA results.

Quantification of Cystic Fibrosis Lung Disease with Radiomics-based CT Scores.

Purpose: To develop radiomics-based CT scores for assessing lung disease severity and exacerbation risk in adult patients with cystic fibrosis (CF).

Materials And Methods: This two-center retrospective observational study was approved by an institutional ethics committee, and the need for patient consent was waived. A total of 215 outpatients with CF referred for unenhanced follow-up chest CT were evaluated in two different centers between January 2013 and December 2016.

Club Cell Loss as a Feature of Bronchiolization in ILD.

Distal airway metaplasia may precede honeycombing in progressive fibrosing interstitial lung disease (ILD). The SCGB1A1 bronchiolar-specific club cell may play a role in this aberrant regenerative process. To assess the presence of club cells in the small airways of patients suffering from ILD.

Cachexia - sarcopenia as a determinant of disease control rate and survival in non-small lung cancer patients receiving immune-checkpoint inhibitors.

Purpose: The metabolic changes associated with cachexia - sarcopenia syndrome might down-regulate antitumor immunity. We hypothesized that this syndrome reduces efficiency of immune checkpoint inhibitors (ICPI) in non-small cell lung cancer (NSCLC).

Methods: The records of 142 consecutive NSCLC patients receiving first- or second-line anti-Programmed cell death protein 1) ICPI were reviewed.

Systemic air embolism depicted on systematic whole thoracic CT acquisition after percutaneous lung biopsy: Incidence and risk factors.

Objectives: To evaluate the incidence and risk factors of systemic air embolism (SAE) depicted on systematic whole thoracic CT performed after percutaneous lung biopsy.

Methods: A total of 559 CT-guided lung biopsies performed between April 2014 and May 2016 were retrospectively evaluated. SAE was defined by the presence of air in the aorta or left cardiac cavities seen on whole thorax CT images acquired after needle withdrawal.

Poor Concordance between Sequential Transbronchial Lung Cryobiopsy and Surgical Lung Biopsy in the Diagnosis of Diffuse Interstitial Lung Diseases.

The diagnostic concordance between transbronchial lung cryobiopsy (TBLC)-versus surgical lung biopsy (SLB) as the current gold standard-in interstitial lung disease (ILD) cases requiring histology remains controversial. To assess diagnostic concordance between TBLC and SLB sequentially performed in the same patients, the diagnostic yield of both techniques, and subsequent changes in multidisciplinary assessment (MDA) decisions. A two-center prospective study included patients with ILD with a nondefinite usual interstitial pneumonia pattern (on high-resolution computed tomography scan) confirmed at a first MDA.

A Randomized Non-Comparative Phase II Study of Anti-Programmed Cell Death-Ligand 1 Atezolizumab or Chemotherapy as Second-Line Therapy in Patients With Small Cell Lung Cancer: Results From the IFCT-1603 Trial.

Introduction: This randomized phase II trial aimed at evaluating the engineered programmed cell death ligand 1 (PD-L1) antibody atezolizumab in SCLC progressing after first-line platinum-etoposide chemotherapy.

Methods: Patients were randomized 2:1 to atezolizumab (1200 mg intravenously every 3 weeks) until progression or unacceptable toxicity, or conventional chemotherapy (up to 6 cycles of topotecan or re-induction of initial chemotherapy). Patients were not selected based on PD-L1 tissue expression.

Synchronous multiple non-small cell lung cancers in an allograft lung recipient.

We described a case report of synchronous non-small cell lung cancers arising in lung transplants after allograft. Immunosuppressive therapy of the recipient induced an accelerated growth rate of primary tumour and metastases as was been observed in orthotopic liver allograft for hepatocellular carcinoma.
