Lung Transplantation
2014
For patients with terminal lung conditions such chronic obstructive lung disease (COPD), lung transplantation (LuTx) offers treatment to improve quality of life and additionally, in those with certain other diseases—e.g., cystic fibrosis (CF), idiopathic pulmonary fibrosis (IPF), and pulmonary arterial hypertension (PAH)—to prolong life (1, 2, e1). It is used at the point when, despite treatment by all available conservative methods, the patient’s quality of life will be clearly impaired or life shortened if transplantation does not take place (3, 4, e2). At present, there are four main surgical options when performing a lung transplantation (5, e3, e4). These are: Unilateral (single lung) …
Functional imaging of airway distensibility
2014
The physiological function of the respiratory system is essential in distending airway smooth muscle and maintaining airway patency. Deep inspirations can reverse contracted airways and protect airways from subsequent bronchospastic stimuli. Obstructive lung diseases may lead to impairment of the beneficial effects of lung inflation through either change in the airway wall or lung parenchyma. Conventional pulmonary function measurements are unable to assess airway stiffness, based on changes in airway size with lung inflation (distensibility). However, high-resolution computed tomography (HRCT) is unique in that it can be used to measure airway distensibility in animals and in humans. Funct…
Pharmacotherapy of COPD in Central and Eastern Europe - The POPE study
2016
Introduction: In Central and Eastern Europe (CEE) the burden of chronic obstructive pulmonary disease (COPD) is high. It remains unknown whether patients are treated in line with GOLD recommendations or according to their phenotypes. Our aim was to analyze the treatment patterns of COPD in CEE. Methods: In the frame of the POPE study (ClinicalTrials.gov - NCT02119494) data including pharmacotherapy were collected in patients with stable COPD across 11 CEE countries. Results: 3366 patients (66±9 yrs, 70% male, FEV 1 53±18%) participated in the study. In all GOLD categories, the most widely used medications were long-acting beta-2 agonists (LABA), followed by long-acting antimuscarinic agents…
How Can We Assess the Perception of Induced Dyspnea in Chronic Obstructive Pulmonary Disease?
2004
Objective TO evaluate various methods for studying the perception of dyspnea in chronic obstructive pulmonary disease (COPD) using a new parameter, the change in Borg scale rating, and others already in use: the linear regression slope and the application of Stevens' law to the response-perception curve-ie change in forced expiratory volume in 1 second (ΔFEV 1 )-change in dyspnea (Adyspnea). Patients and method A bronchial challenge test was performed on 70 patients with stable COPD and no contraindications for performing the test (European Respiratory Society criteria), during which dyspnea was measured (Borg scale) after each nebulization. Perception was analyzed using: a ) the linear reg…
Risk Factors for Pulmonary Embolism in Patients with Paralysis and Deep Venous Thrombosis
2021
Background. Venous thromboembolism is a frequent complication and an important cause of death in patients with paralysis. We aimed to investigate predictors of pulmonary embolism (PE) and the impact of PE on the survival of patients with paralysis in comparison to those with deep venous thrombosis or thrombophlebitis (DVT). Methods: Patients were selected by screening the German nationwide inpatient sample (2005–2017) for paralysis, and were stratified for venous thromboembolism (VTE) and the VTE-sub-entity PE (ICD-code I26). Impact of PE on mortality and predictors for PE were analyzed. Results: Overall, 7,873,769 hospitalizations of patients with paralysis were recorded in Germany 2005–20…
Iatrogenic pulmonary artery dissection in patient with ostium secundum interatrial septum defect
2020
Pulmonary artery dissection is a rare and lethal condition. Few cases are reported in the literature, and most are derived from autopsies. In most cases, pulmonary artery dissection is a complication of chronic pulmonary hypertension leading to pulmonary artery aneurysm but there are other causes. We describe a case of iatrogenic pulmonary artery dissection in an elderly patient with ostium secundum defect. In particular, we describe the role of cardiac magnetic resonance in making this diagnosis and guiding future therapeutic decisions.
Hemodynamic monitoring and management in patients undergoing high risk surgery: a survey among North American and European anesthesiologists
2011
Abstract Introduction Several studies have demonstrated that perioperative hemodynamic optimization has the ability to improve postoperative outcome in high-risk surgical patients. All of these studies aimed at optimizing cardiac output and/or oxygen delivery in the perioperative period. We conducted a survey with the American Society of Anesthesiologists (ASA) and the European Society of Anaesthesiology (ESA) to assess current hemodynamic management practices in patients undergoing high-risk surgery in Europe and in the United States. Methods A survey including 33 specific questions was emailed to 2,500 randomly selected active members of the ASA and to active ESA members. Results Overall,…
Elevated systolic pulmonary artery pressure for prediction of myocardial necrosis and right ventricular dysfunction in acute pulmonary embolism
2016
Kontext: Echokardiografie je v soucasnosti hlavni metodou pro vysetřeni dysfunkce prave komory (right ventricular dysfunction, RVD) u akutni plicni embolie (PE). Dysfunkce prave komory je sice spojena s nepřiznivou prognozou, dosud vsak nebyla přijata žadna obecně uznavana definice. Systolický tlak v plicnici (systolic pulmonary artery pressure, sPAP) větsinou neni soucasti kriterii RVD. Cilem nasi studie bylo zhodnotit možnost použiti sPAP v predikci nekrozy myokardu a RVD u akutni PE.Metody: Retrospektivně byly analyzovany udaje 182 pacientů s akutni PE. Pacienti s PE a hodnotami sPAP ≤ 30 mm Hg byli srovnavani s pacienty s PE a hodnotami sPAP > 30 mm Hg. Vztahy mezi sPAP na jedne straně …
Levosimendan in the treatment of patients with acute cardiac conditions: an expert opinion of the Association of Intensive Cardiac Care of the Polish…
2020
Levosimendan is a new inodilator which involves 3 main mechanisms: increases the calcium sensitivity of cardiomyocytes, acts as a vasodilator due to the opening of potassium channels, and has a cardioprotective effect. Levosimendan is mainly used in the treatment of acute decompensated heart failure (class IIb recommendation according to the European Society of Cardiology guidelines). However, numerous clinical trials indicate the validity of repeated infusions of levosimendan in patients with stable heart failure as a bridge therapy to heart transplantation, and in patients with accompanying right ventricular heart failure and pulmonary hypertension. Due to the complex mechanism of action,…
