Identification Of Molecular Markers Associated With Copd In Non-Smokers And Smokers: A Bioinformatics Analysis, Agede O. Ayodele, Isa M. Wasagu, Ademola E. Fawibe, Alakija K. Salami

The University of Louisville Journal of Respiratory Infections

Background

Even though the proportional burden of COPD among never-smokers is significant in both developing and developed nations, accounting for around 30% of all COPD in the community, there is little awareness of the prevalence of COPD in this population. Understanding the molecular processes that underlie COPD in nonsmokers is essential.

Methods

Dataset (GSE146560) was acquired from the Gene Expression Omnibus (GEO). The limma and clusterProfiler software tools were used to identify differentially expressed genes (DEGs) and conduct a functional enrichment analysis respectively.

Results

In all, 10,583 DEGs were found, of which 1,065 were up-regulated and 9,518 were down-regulated. The …

Functional Status Among Patients With Established Copd Attending Tertiary Hospitals In Dar Es Salaam, Tanzania, Peter M. Tumbo

Theses & Dissertations

Background

Chronic Obstructive Pulmonary Disease (COPD) is a common, preventable and treatable non communicable disease that is characterized by persistent respiratory symptoms and airflow limitation that is due to airway and/or alveolar abnormalities usually caused by significant exposure to noxious particles or gases and influenced by host factors including abnormal lung development. It is associated with a lot of risk factors such as smoking, biomass fuel use for cooking and air pollutants in general.

Objectives

The primary objective of this research was to determine the functional status of patients with COPD. The secondary objectives were to determine the factors influencing …

Gold In Practice: Chronic Obstructive Pulmonary Disease Treatment And Management In The Primary Care Setting, Barbara P. Yawn, Matthew L. Mintz, Dennis E. Doherty

Internal Medicine Faculty Publications

Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality. Early detection and appropriate treatment and management of COPD can lower morbidity and perhaps mortality. Clinicians in the primary care setting provide the majority of COPD care and are pivotal in the diagnosis and management of COPD. In this review, we provide an overview of the Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2020 report, with a focus on the management of COPD in the primary care setting. We discuss the pathophysiology of COPD; describe COPD risk factors, signs, and symptoms that may facilitate earlier diagnosis …

Invasive Pulmonary Infection By Syncephalastrum Species: Two Case Reports And Review Of Literature, Memoona Irshad, Nosheen Nasir, Urooj Haider Hashmi, Joveria Farooqi, Syed Faisal Mahmood

Section of Internal Medicine

Background: Syncephalastrum species belong to the class Zygomycetes and order Mucorale. These are found in the environment and tropical soil, usually presenting as colonizers and rarely cause human infection. Syncephalastrum racemosum is a species of the genus Syncephalastrum and is the most commonly identified pathogen. Most cases are reported in immunocompromised individuals, such as patients on long term steroids, poorly controlled diabetes, or patients with malignancy.
Case presentation: We are describing two cases of rare fungal infection by Syncephalastrum species causing invasive pulmonary manifestation. Both patients had compromised immune status and presented with worsening dyspnea to the emergency room. Both …

Intravenous Glucocorticoids Provide No Additional Benefit Over Oral Glucocorticoids In Chronic Obstructive Pulmonary Disease Exacerbation, Alexander C. Waselewski

Clinical Research in Practice: The Journal of Team Hippocrates

A critical appraisal and clinical application of de Jong YP, Uil SM, Grotjohan HP, Postma DS, Kerstjens HA, van den Berg JW. Oral or IV prednisolone in the treatment of COPD exacerbations: a randomized, controlled, double-blind study. Chest. 2007;132(6):1741-1747. doi: 10.1378/chest.07-0208

Prevalence Of Chronic Obstructive Pulmonary Disease (Copd) Among Rheumatoid Arthritis: Results From National Inpatient Database., Rashmi Dhital, Sijan Basnet, Prakash Paudel, Yam Prasad Acharya, Dilli Ram Poudel

Reading Hospital Internal Medicine Residency

Rheumatoid arthritis (RA) is being increasingly recognized as an important contributor to chronic obstructive pulmonary disease (COPD). Although smoking is a major risk factor, other factors may play a role. We used National Inpatient Sample (NIS) from 2013 to explore this relationship. We used propensity matching with a 1:3 nearest-neighbor-matching algorithm to match 1 RA hospitalization to 3 age- and-sex-matched comparators. In the age- and-sex-matched population, RA had a higher odds of COPD (OR 1.20, 95% CI: 1.17-1.22,

Can Capture Be Used To Identify Undiagnosed Patients With Mild-To-Moderate Copd Likely To Benefit From Treatment?, Nancy K. Leidy, Fernando J. Martinez, Karen G. Malley, David M. Mannino, Meilan K. Han, Elizabeth D. Bacci, Randall W. Brown, Julia F. Houfek, Wassim W. Labaki, Barry J. Make, Catherine A. Meldrum, Wilson Quezada, Stephen Rennard, Byron Thomashow, Barbara P. Yawn

Preventive Medicine and Environmental Health Faculty Publications

Background: COPD Assessment in Primary Care To Identify Undiagnosed Respiratory Disease and Exacerbation Risk (CAPTURE™) uses five questions and peak expiratory flow (PEF) thresholds (males ≤350 L/min; females ≤250 L/min) to identify patients with a forced expiratory volume in 1 second (FEV₁)/forced vital capacity (FVC)11 60%–80% predicted) who may also benefit from diagnosis and treatment.

Methods: Data from the CAPTURE development study were used to test its sensitivity (SN) and specificity (SP) differentiating mild-to-moderate COPD (n=73) from no COPD (n=87). SN and SP for differentiating all COPD cases (mild to severe; n=259) from those without COPD (n=87) were …

The Impact Of Schizophrenia On Copd Readmission Rate Among Hospitalized South Carolinians, Emilienne Y. Watonsi

DNP Research Projects

Due to elevated readmission costs, the Affordable Care Act established the Hospital Readmission Reduction Program in 2012 to curb the 30-day readmission rates. COPD and schizophrenia are two very expensive diseases, COPD national medical costs is projected to be $49.0 billion in 2020; the cost of schizophrenia was 155.7 billion in 2013. The main objective of this study was to determine if schizophrenia is a significant predictor of 30-day readmission following hospitalization for acute exacerbation of COPD after adjusting for age, gender, anxiety, smoking status, T2DM, chronic ischemic heart disease, and GERD. Methods: A retrospective cohort design was used to …

Retrospective Analysis To Describe Associations Between Tumor Necrosis Factor Alpha Inhibitors And Copd-Related Hospitalizations, Neil A. Accortt, James B. Chung, Machaon Bonafede, Brendan L. Limone, David M. Mannino

Preventive Medicine and Environmental Health Faculty Publications

Background: Limited information exists on the impact of tumor necrosis factor inhibition on COPD exacerbations. This retrospective study characterized this impact among COPD patients with underlying autoimmune conditions, exposed to tumor necrosis factor inhibitors (TNFi) and/or non-biologic disease-modifying antirheumatic drugs (DMARDs).
Patients and methods: Adult COPD patients with ≥1 diagnosis for rheumatoid arthritis (RA), psoriasis (PsO), psoriatic arthritis (PsA), or ankylosing spondylitis (AS) before or within 6 months following the index COPD diagnosis were identified from the Truven Health MarketScan^® databases. Patients were required to have a second claim for RA, PsO, PsA, AS, or DMARD use (biologic or …
