BACKGROUND: While obesity is a chronic condition that predisposes patients to other more serious disorders, the prevalence and the documentation of obesity as diagnosis has not been extensively studied in hospitalized patients. We conducted a retrospective chart review to investigate the prevalence and documentation of obesity as a diagnosis among patients admitted to our medical center. METHOD: IRB approval was obtained for this retrospective study. Body mass index (BMI) as per CDC, admission and discharge diagnosis of obesity and common comorbidities (hypertension, diabetes, hyperlipidemia, coronary artery disease, congestive heart disease, chronic kidney disease and chronic obstructive pulmonary disease) were recorded...

Pulmonary hypertension is a co-morbidity, which strongly participates in morbi-mortality in patients with chronic obstructive pulmonary disease (COPD). Recent findings showed that bromodomain-containing proteins, in charge of reading histone acetylation, could be involved in pulmonary arterial hypertension. Our aim was to study the effect of I-BET151, an inhibitor of bromodomain and extra-terminal domain (BET), on the right ventricle hypertrophy and pulmonary hypertension, induced by a combination of chronic hypoxia and pulmonary inflammation, as the two main stimuli encountered in COPD...

PURPOSE: Comorbidities associated with chronic obstructive pulmonary disease (COPD) affect quality of life and increase mortality. Asthma-COPD overlap (ACO) may express a different profile of comorbidities compared to COPD alone. It is unclear how recent changes in GOLD recommendations affect the profile of comorbidities in COPD and ACO. METHODS: Eight hundred and thirty-four patients with COPD were recruited from 67 Hungarian secondary care outpatient clinics, 469 of them had ACO...

BACKGROUND: Pulmonary hypertension (PH) in chronic obstructive pulmonary disease (COPD) is suggested as the consequence of emphysematous destruction of vascular bed and hypoxia of pulmonary microenvironment, mechanisms underpinning its pathogenesis however remain elusive. The dysregulated expression of nicotinamide adenine dinucleotide phosphate (NADPH)-oxidases and superoxide generation by pulmonary vasculatures have significant implications in the hypoxia-induced PH. METHODS: In this study, the involvement of NADPH oxidase subunit 4 (NOX4) in pulmonary arteriolar remodeling of PH in COPD was investigated by ascertaining the morphological alteration of pulmonary arteries and pulmonary blood flow using cardiac magnetic resonance imaging (cMRI), and the expression and correlation of NOX4 with pulmonary vascular remodeling and pulmonary functions in COPD lungs...

This study uses a highly fidelity computational simulator of pulmonary physiology to evaluate the impact of a soluble guanylate cyclase (sGC) modulator on gas exchange in patients with chronic obstructive pulmonary disease (COPD) and pulmonary hypertension (PH) as a complication. Three virtual patients with COPD were configured in the simulator based on clinical data. In agreement with previous clinical studies, modeling systemic application of an sGC modulator results in reduced partial pressure of oxygen (PaO2 ) and increased partial pressure of carbon dioxide (PaCO2 ) in arterial blood, if a drug-induced reduction of pulmonary vascular resistance (PVR) equal to that observed experimentally is assumed...

Background: The impact of radiation dose to the heart in early-stage lung cancer patients treated with definitive stereotactic body radiation therapy (SBRT) is not well known. We, therefore, analyzed whether higher radiation dose to the heart would lead to an increase in cardiac toxicity and overall mortality. Methods: Seventy-four patients with 75 tumors treated definitively with SBRT for early-stage non-small cell lung cancer (NSCLC) and two cases of limited-stage small cell lung cancer (SCLC) with an average follow-up of 35 months (range, 1-130 months) were retrospectively analyzed...

Although often clinically unrecognized, the pulmonary circulation is frequently affected in patients with chronic obstructive pulmonary disease (COPD), and the presence of pulmonary vascular disease is associated with poor prognosis and frequent exacerbations. In most cases the presenting pulmonary hypertension (PH) is relatively mild, but in a subset of COPD patients, the presence of certain clinical features supports the existence of a "pulmonary vascular phenotype". Such a phenotype would be characterized by severe pre-capillary PH with strongly elevated pulmonary vascular resistance, moderate airflow limitation, severely decreased diffusion capacity for carbon monoxide, normo- or hypocapnia, circulatory exercise limitation and progressive right heart failure...

BACKGROUND: Ischemic heart disease (IHD) and chronic airway disease (COPD and Asthma) are major epidemics accounting for significant mortality and morbidity. The combination presents many diagnostic challenges. Clinical symptoms and signs frequently overlap. There is a need for airway evaluation in these patients to plan appropriate management. METHODS: Consecutive stable IHD patients attending the cardiology OPD in a tertiary care centre were interviewed for collecting basic demographic information, brief medical, occupational, personal history and risk factors for coronary artery disease and airway disease, modified medical research centre (MMRC) grade for dyspnea, quality of life-St...

Grade 3 primary graft dysfunction (PGD3) represents the most important risk factor for patient mortality during the first year after lung transplantation (LTX). We investigated whether pretransplant pulmonary hypertension (PH) is a risk factor for the development of PGD3. This retrospective, single-center cohort study included 96 candidates undergoing right heart catheterization (RHC) prior to being listed for LTX between March 2000 and October 2015. Based on their mean pulmonary artery pressure (mPAP) levels, the patients were classified into 3 groups: (1) <25 mm Hg, (2) 25-34 mm Hg and (3) ≥35 mm Hg...

INTRODUCTION: Bilateral internal thoracic artery (BITA) grafting in patients with diabetes mellitus is controversial due to a higher risk for sternal infection. The purpose of this study is to compare the rates of mediastinitis as well as mortality rates of BITA grafting to that of single internal thoracic artery (SITA) grafting and saphenous vein grafts in patients with diabetes. METHODS: Between 2007 and 2015 all consecutive diabetic patients with multivessel disease who underwent primary coronary artery bypass graft surgery with BITA were compared with patients who underwent coronary artery bypass graft surgery with SITA and saphenous vein grafts (the control group)...

Background: Asymmetric dimethylarginine (ADMA) has emerged as a risk marker for many conditions related to pulmonary hypertension (PH); however, little is known about ADMA and symmetric dimethylarginine (SDMA) plasma concentrations in chronic obstructive pulmonary disease (COPD). Our interest centers on the role of ADMA in regulation of endothelial function in COPD and secondary PH. The aim of the present study was to evaluate the serum ADMA, SDMA, and L-arginine concentrations in COPD and its association with PH...

BACKGROUND: Pulmonary thromboendarterectomy (PTE) is a recognized treatment for patients with chronic thromboembolic pulmonary hypertension (CTEPH), with good long-term hemodynamic results. The aim of this study was to test the hypothesis that the dynamics of health-related quality of life (QoL), 1 year after PTE, depend both on the clinical determinants associated with the underlying disease and the adverse events occurring in the early postoperative period. METHODS: This prospective cohort study included 136 patients with CTEPH...

The repurposing of drug delivery by the pulmonary route has been applied to treatment and prophylaxis of an increasingly wide range of respiratory diseases. Repurposing has been most successful for the delivery of inhaled bronchodilators and corticosteroids in patients with asthma and chronic obstructive pulmonary disease (COPD). Repurposing utilizes the advantages that the pulmonary route offers in terms of more targeted delivery to the site of action, the use of smaller doses, and a lower incidence of side-effects...
