Pulmonary microvascular architecture in hereditary haemorrhagic telangiectasia
2017
A 24-year-old Caucasian man was admitted with a known hereditary haemorrhagic telangiectasia (HHT) and heterozygous mutation of factor V Leiden following episodes of cerebral infarctions in occipital lobes, cerebellum and brainstem. In his case history, the patient underwent several interventional embolisation of arteriovenous (AV) malformations in the middle and lower lobes (figure 1). However, those were not completely successful as the malformations were diffuse. We performed video-assisted thoracoscopic surgery with a resection of the middle lobe and a wedge resection of segment 10. Figure 1 CT scans depict the pulmonary arteriovenous malformations after re-embolisation in the middle lo…
Personalised mechanical ventilation tailored to lung morphology versus low positive end-expiratory pressure for patients with acute respiratory distr…
2019
The effect of personalised mechanical ventilation on clinical outcomes in patients with acute respiratory distress syndrome (ARDS) remains uncertain and needs to be evaluated. We aimed to test whether a mechanical ventilation strategy that was personalised to individual patients' lung morphology would improve the survival of patients with ARDS when compared with standard of care.We designed a multicentre, single-blind, stratified, parallel-group, randomised controlled trial enrolling patients with moderate-to-severe ARDS in 20 university or non-university intensive care units in France. Patients older than 18 years with early ARDS for less than 12 h were randomly assigned (1:1) to either th…
Determinants of diagnostic delay in chronic thromboembolic pulmonary hypertension: results from the European CTEPH Registry.
2018
Chronic thromboembolic pulmonary hypertension (CTEPH) is characterised by chronic thrombi in the pulmonary arterial bed, causing pulmonary hypertension [1–3]. CTEPH is diagnosed in ∼3% of patients who survive a symptomatic acute pulmonary embolism (PE) [4]. While the surgical removal of chronic fibrotic thrombotic vascular occlusions by pulmonary endarterectomy (PEA) may cure most patients with CTEPH by normalising pulmonary artery hemodynamics and improving symptoms, patients who remain not operated or do not undergo balloon pulmonary angioplasty have severe functional limitations, and poor quality of life and survival [5, 6]. Since the natural course of CTEPH involves progressive remodell…
Preliminary development of a questionnaire to measure the extra-pulmonary symptoms of severe asthma
2021
Abstract Background Research into the effects of asthma treatments on the extra-pulmonary symptoms of severe asthma is limited by the absence of a suitable questionnaire. The aim was to create a questionnaire suitable for intervention studies by selecting symptoms that are statistically associated with asthma pathology and therefore may improve when pathology is reduced. Methods Patients attending a specialist asthma clinic completed the 65-item General Symptom Questionnaire (GSQ-65), a questionnaire validated for assessing symptoms of people with multiple medically unexplained symptoms. Lung function (FEV1%) and cumulative oral corticosteroids (OCS) calculated from maintenance dose plus ex…
Detection of lung cancer with electronic nose and logistic regression analysis.
2018
Lung cancer is a very common malignancy with a low five-year survival rate. Artificial olfactory sensor (electronic nose) is a tool that recently has been studied as a probable optimal screening tool for early detection of lung cancer, but still no statistical method has been put forward as the preferable one. The aim of the study was to explore the use of logistic regression analysis (LRA) to analyse patients' exhaled breath samples with electronic nose in order to differentiate lung cancer patients (regardless of the stage of the cancer) from patients with other lung diseases and healthy individuals. Patients with histologically or cytologically verified, untreated lung cancer, patients w…
Impact of video-assisted thoracic surgery approach on postoperative mortality after lobectomy in octogenarians.
2019
The number of octogenarians who present with localized lung cancer eligible for surgical resection is increasing. Video-assisted thoracic surgery lobectomy has been widely accepted, but the potential benefit in octogenarians is not well established, especially for postoperative mortality. This study aimed to assess the impact of a video-assisted thoracic surgery approach on postoperative mortality after lobectomy for lung cancer in octogenarians.From January 2005 to December 2016, all patients aged more than 80 years who received lobectomy treatment for lung cancer were retrieved from the French Administrative Database. The end point was 30-day postoperative death. A propensity score was ge…
Secondary Carina and Lobar Bronchi Stenting in Patients with Advanced Lung Cancer: Is It Worth the Effort? A Clinical Experience
2020
Background: The lobar airway stenting remains an endoscopic procedure not well standardized in patients with locally advanced lung cancer disease. The goal of this study was to evaluate technical feasibility, clinical outcome, and complications of different stents in patients with malignant lesions involving lobar bronchi, primary and secondary carina. Methods: Between November 2008 and October 2013, we retrospectively analyzed 146 patients with benign and malignant tracheobronchial stenosis who underwent airway stent insertion below main carina and main bronchi. Results: In all, 170 airway stenting procedures were performed on 146 patients. In all, 51 of them with malignant peripheral airw…
C-reactive Protein Levels After Esophagectomy Are Associated With Increased Surgical Trauma and Complications.
2020
With the introduction of minimally invasive esophagectomy, postoperative complications rates have decreased. Daily laboratory tests are used to screen patients for postoperative complications. The course of inflammatory indicators after esophagectomy after different surgical approaches has not been described yet. The aim of the study was to describe the postoperative C-reactive protein (CRP) and leukocyte levels after different surgical approaches for esophagectomy and relate it to postoperative complications.Between 2010 and 2018, 217 consecutive patients underwent thoracoabdominal esophagectomy with gastric conduit reconstruction. Blood tests to assess CRP and leukocytes were performed da…
Predictors of need for noninvasive ventilation during respiratory tract infections in medically stable, non-ventilated subjects with amyotrophic late…
2014
BACKGROUND: Acute lower respiratory infections can impair muscle strength in patients with amyotrophic lateral sclerosis (ALS). When associated with an increase in load on the respiratory system, this situation may precipitate hypercapnic respiratory failure in non-ventilated patients with ALS. The aim of this study was to determine whether a clinical or functional parameter can predict the need for noninvasive ventilation (NIV) during an acute respiratory infection for medically stable, non-ventilated patients with ALS. METHODS: This was a prospective study involving all non-ventilated subjects with ALS admitted due to an acute respiratory infection to a respiratory care unit from a tertia…
In-hospital mortality following lung cancer resection: nationwide administrative database.
2016
Our aim was to determine the effect of a national strategy for quality improvement in cancer management (the “Plan Cancer”) according to time period and to assess the influence of type and volume of hospital activity on in-hospital mortality (IHM) within a large national cohort of patients operated on for lung cancer.From January 2005 to December 2013, 76 235 patients were included in the French Administrative Database. Patient characteristics, hospital volume of activity and hospital type were analysed over three periods: 2005–2007, 2008–2010 and 2011–2013.Global crude IHM was 3.9%: 4.3% during 2005–2007, 4% during 2008–2010 and 3.5% during 2011–2013 (p<0.01). 296, 259 and 209 centres p…
