Lung cancer is the third most common cancer in Belgium in 2017 and remains the leading cause of cancer death worldwide. There is no longer any doubt that the main cause of lung cancer is smoking. However, the prevalence of lung cancer in never-smokers has been increasing overtime. Moreover, it is now recognized that the lung cancer of non-smoker patients has very distinct characteristics. In this retrospective cohort study (N = 520), we describe the characteristics of non-smoker patients and their non-small cell lung carcinoma and compare them to those of smokers. The patients included in this study were whose with a new diagnostic of lung cancer made at the Liège University Hospital of Liège over 2 years round. Non small cell lung cancer occurring in never-smokers patients is more often seen in young and very old patients, more frequent in female, essentially adenocarcinoma and often associated with mutations. This work confirms that lung cancer in never-smokers shows different features than lung cancer seen in patients with a smoking history.

Background: Asthmatics and patients with chronic obstructive pulmonary disease (COPD) have more severe outcomes with viral infections than people without obstructive disease., Objective: To evaluate if obstructive diseases are risk factors for intensive care unit (ICU) stay and death due to coronavirus disease 2019 (COVID19)., Methods: We collected data from the electronic medical record from 596 adult patients hospitalized in University Hospital of Liege between March 18 and April 17, 2020, for severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) infection. We classified patients into 3 groups according to the underlying respiratory disease, present before the COVID19 pandemic., Results: Among patients requiring hospitalization for COVID19, asthma and COPD accounted for 9.6% and 7.7%, respectively. The proportions of asthmatics, patients with COPD, and patients without obstructive airway disease hospitalized in the ICU were 17.5%, 19.6%, and 14%, respectively. One-third of patients with COPD died during hospitalization, whereas only 7.0% of asthmatics and 13.6% of patients without airway obstruction died due to SARS-CoV2. The multivariate analysis showed that asthma, COPD, inhaled corticosteroid treatment, and oral corticosteroid treatment were not independent risk factors for ICU admission or death. Male gender (odds ratio [OR]: 1.9; 95% confidence interval [CI]: 1.1-3.2) and obesity (OR: 8.5; 95% CI: 5.1-14.1) were predictors of ICU admission, whereas male gender (OR 1.9; 95% CI: 1.1-3.2), older age (OR: 1.9; 95% CI: 1.6-2.3), cardiopathy (OR: 1.8; 95% CI: 1.1-3.1), and immunosuppressive diseases (OR: 3.6; 95% CI: 1.5-8.4) were independent predictors of death., Conclusion: Asthma and COPD are not risk factors for ICU admission and death related to SARS-CoV2 infection., (Copyright © 2020 The Authors.

Objectives: . To investigate the dose-response relationship between cardiovascular or psychotropic medication dosages and falling orthostatic blood pressure in geriatric inpatients., Methods: . This cross-sectional study included 100 consecutive geriatric inpatients of a Belgian hospital. The end points were the maximum changes of systolic (sBP) and diastolic (dBP) blood pressure in a standing up position at one or three minutes. The dosages of six classes of vascular and five classes of psychotropic medications were expressed in terms of a proportion of defined daily doses (DDD). Bivariate and multivariate linear regression models were used., Results: . The 100 geriatric patients (85 ± 5 years, 58 % women) received 7.7 ± 4 medications (mean DDD: vascular = 1.0, psychotropic = 0.74) on the day of an orthostatic test (lying sBP: 136 ± 21; dBP: 72 ± 14 mm Hg). In a standing position, sBP and dBP fell by 12 ± 17 and 11 ± 5 mmHg, respectively. At the individual level, BP change was not correlated with vascular DDD (sBP: p = 0.07, r 2  = 0.04; dBP: p = 0.59; r 2  = 0.004) nor with psychotropic DDD (sBP: p = 0.14, r 2  = 0.02; dBP: p = 0.82; r 2  = 0.0). In multivariate analysis, sBP drop was positively associated with age, diabetes, falls history, and number of medications, but not with the DDD of any of the medication classes, while dBP drop was positively associated with age, diabetes, stroke and anaemia, but again with the DDD of any of the medication classes., Conclusion: . No correlation was found between vascular and psychotropic medication dosages and the orthostatic blood pressure drop expressed as a continuous variable.

Introduction: The incidence of pleural disease continues to increase worldwide. Medical thoracoscopy remains the standard method for exploration of the pleural cavity., Method: We report the retrospective evaluation, the efficacy and the observed complications in 1024 medical thoracoscopies undertaken in the University Hospital of Liège between 2000 and 2017., Results: In total, 100 pneumothoraces and 400 benign and 501 malignant pleural diseases were identified. The main indication for thoracoscopy remains the diagnosis of an exudative, lymphocytic pleural effusion of unknown aetiology after thoracocentesis. The diagnostic sensibility of thoracoscopy was 99.2% in distinguishing benign from malignant pleural disease. Talc pleurodesis was performed in 69.5% of the total population and in 66.1% of pleural effusions or thickening. Failure of pleurodesis was observed in 11% of the patients with recurrent pneumothorax and in 7.8% of neoplastic pleural effusion. We report a mortality of 0.6% in the 30 days post procedure, long duration of drainage in 8.3% and serious complications in 4.7%. In 22/1024 (2.1%) thoracoscopic evaluation was not feasible because of dense pleural fibrosis., Conclusion: Medical thoracoscopy is a safe, well-tolerated procedure with high accuracy in the diagnostic and therapeutic management of pleural disease., (Copyright © 2019 SPLF.
