Bulbar impairment score and survival of stable amyotrophic lateral sclerosis patients after noninvasive ventilation initiation
2018
There is general agreement that noninvasive ventilation (NIV) prolongs survival in amyotrophic lateral sclerosis (ALS) and that the main cause of NIV failure is the severity of bulbar dysfunction. However, there is no evidence that bulbar impairment is a contraindication for NIV. The aim of this study was to determine the effect of bulbar impairment on survival in ALS patients with NIV. ALS patients for whom NIV was indicated were included. Those patients who refused NIV were taken as the control group. 120 patients who underwent NIV and 20 who refused NIV were included. The NIV group presented longer survival (median 18.50 months, 95% CI 12.62–24.38 months) than the no-NIV group (3.00 mont…
Dynamic hyperinflation during the 6-min walk test in severely asthmatic subjects
2018
We tested the hypothesis that dynamic hyperinflation develops in severe asthmatic subjects during exercise. Changes in inspiratory capacity (IC) were measured during the 6-min walk test (6MWT) in severe asthmatic subjects compared with chronic obstructive pulmonary disease (COPD) subjects with a similar degree of bronchial obstruction. We assessed whether changes in IC were associated with changes in dyspnoea perception. 27 severe asthmatic subjects (10 males and 17 females) and 43 COPD subjects (35 males and eight females) were recruited. The two groups performed similarly in the 6MWT (p=0.90). At the end of the test, the Borg score increased significantly in both groups (mean difference: …
Evaluation of a multicomponent grading system for obstructive sleep apnoea: the Baveno classification
2021
New findings on pathophysiology, epidemiology, and outcome have raised concerns on the relevance of the apnoea–hypopnoea index (AHI) in the classification of obstructive sleep apnoea (OSA) severity. Recently, a multicomponent grading system decision integrating symptomatology and comorbidities (Baveno classification), was proposed to characterise OSA and to guide therapeutic decisions. We evaluated whether this system reflects the OSA population, whether it translates into differences in outcomes, and whether the addition of AHI improves the scheme. A total of 14 499 OSA patients from the European Sleep Apnoea Database cohort were analysed. The groups were homogeneously distributed and were…
A review of venous thromboembolism in COVID‐19: A clinical perspective
2021
Abstract Coronavirus disease‐19 (COVID‐19) started in Wuhan, China in December 2019 and spread to all around the world in a short period of time. Hospitalized patients with COVID‐19 mostly could suffer from an abnormal coagulation activation risk with increased venous thrombosis events and a poor clinical course. The reported incidence rates of thrombotic complications in hospitalized COVID‐19 patients vary between 2.6 and 85% (both in non‐critically ill and critically ill patients). The risk of venous thromboembolism is not known in non‐hospitalized patients with COVID‐19. There are numerous studies and guidelines for administration of thromboprophylaxis for COVID‐19 cases. All hospitalize…
Stratification of eosinophilic asthma patients treated with reslizumab and GINA Step 4 or 5 therapy
2017
Reslizumab, an anti-interleukin-5 monoclonal antibody, significantly reduces exacerbation frequency and improves lung function, asthma control and quality of life in adults with severe eosinophilic asthma, as demonstrated in Phase III studies. This secondary analysis assessed reslizumab's efficacy in patients receiving baseline treatment per Global Initiative for Asthma (GINA) Step 4 and Step 5 guidelines. Pooled data from duplicate, Phase III, reslizumab versus placebo studies in patients with severe eosinophilic asthma (blood eosinophils ≥400 cells·µL−1) were stratified by baseline therapy. Efficacy assessments were exacerbation rates and changes from baseline forced expiratory volume in …
Response to mepolizumab treatment is sustained across 4-weekly dosing periods
2020
Background Mepolizumab (100 mg delivered s.c. every 4 weeks) is indicated for add-on maintenance treatment for patients with severe eosinophilic asthma. Mepolizumab has been shown to reduce exacerbations and the requirement for daily oral corticosteroids, and improve asthma control and symptoms. However, data on the durability of the response to mepolizumab during dosing periods are limited. The aim of this study was to investigate the efficacy profile in patients with severe eosinophilic asthma over the 4-weekly dosing period for various fixed mepolizumab doses. Methods This was a post hoc analysis of data from the phase IIb/III DREAM study. Patients ≥12 years of age with severe eosinophil…
A single-institution retrospective analysis of metachronous and synchronous metastatic bronchial neuroendocrine tumors
2018
Background: Broncho-pulmonary neuroendocrine tumors (bpNETs) are rare malignancies and there is no consensus on therapeutical management of metastatic disease and follow-up after radical resection. Methods: Clinical records of patients with a cytological or histological diagnosis of bpNETs and distant metastases (metachronous or synchronous), evaluated at the European Institute of Oncology between 1997 and 2014, were retrospectively analyzed. Data on patient demographics, pathology, imaging exams, surgical and non-surgical treatments were collected. P value descriptive data, uni- and multi-variate survival analysis were generated for all variables. Results: With a median follow-up of 53 [9–…
Arterial stiffness in symptomatic smokers with normal lung function
2017
Chronic obstructive pulmonary disease (COPD) is associated with cardiovascular morbidity and mortality. Arterial stiffness and endothelial dysfunction index are validated surrogate cardiovascular markers and are increased in subjects with COPD. We tested whether increased arterial stiffness and endothelial dysfunction occur in symptomatic smokers with no evidence of bronchial obstruction. Clinical and lung functional assessments were conducted in smoker subjects with chronic respiratory symptoms and in COPD patients. Pulse wave velocity (PWV), aortic augmentation index (AIx) and reactive hyperaemia index (RHI) were measured to estimate the cardiovascular risk. 48 smokers (male n=37, female …
Is an activity volume threshold really realistic for lung cancer resection?
2018
IF 1.804 (2017); International audience; Background:We analyzed volume as a continuous variable to estimate threshold, which is a methodology rarely seen in the literature. The objective of this work was to assess hospital volume for lung cancer (LC) surgery and to establish the associated threshold for acceptable in-hospital mortality (IHM). Data was obtained from the French national medico-administrative database.Methods:From January 2005 to December 2016, data from 108,571 patients operated for LC in France were collected from the national administrative database. To estimate the volume threshold, hierarchical logistic regression models were developed.Results:The crude IHM rate was 5.2% …
The Burden of Rhinitis and Rhinoconjunctivitis in Adolescents
2014
Purpose Rhinitis and conjunctivitis are common diseases worldwide that are frequently associated. Nevertheless, the risk factors for rhinoconjunctivitis are not well-described and the impact of conjunctivitis on rhinitis and asthma in children remains unknown. This study explored the different risk factors and evaluated the burden of rhinoconjunctivitis among adolescents. Methods This was a cross-sectional study conducted on a random sample of schoolchildren, aged 10-17 years, using skin prick tests and a self-administered questionnaire on respiratory health investigating the impact of rhinitis and rhinoconjunctivitis on daily activities. Results A complete evaluation was obtained for 2,150…
