Little is known about chronic obstructive pulmonary disease (COPD) in Chinese nonsmokers. The present study aimed to investigate the profiles of COPD among nonsmokers based on the Chinese Epidemiological Survey of COPD (CESCOPD). In the CESCOPD, 20,245 subjects aged 40 yrs or older were interviewed with questionnaires and spirometry tests. Subjects with a post-bronchodilator forced expiratory v...

Previous studies have shown that microsatellite (MS) DNA instability (MSI) is detectable in sputum cells in chronic obstructive pulmonary disease (COPD) and asthma. The aim of the present study was to investigate whether asthma and COPD could be distinguished at the MS DNA level. DNA was extracted from sputum cells and white blood cells from 63 COPD patients, 60 non-COPD smokers, 36 asthmatics ...

 Background: Vitamin D has a potential to modulate inflammatory response against noxious particles in patients with chronic obstructive pulmonary disease (COPD). The present study was conducted to determine the status of serum vitamin D in COPD versus healthy group. Methods: The patients presented to the outpatient pulmonary clinic of Ayatollah Rouhani Hospital, Babol Iran. Diagnosis of...

To provide high-quality guideline-based care for patients with asthma or chronic obstructive pulmonary disease (COPD) we must first establish the correct diagnosis. The National Asthma and COPD Audit Programme (NACAP) has highlighted an important issue across England, Scotland, Wales that potentially undermines many people airways disease.

Chronic Obstructive Pulmonary Disease (COPD) is a chronic respiratory disease characterized by slow progression and caused the inhalation of harmful particulate matter. Cigarette smoke air pollutants are primary contributing factors. Currently, pathogenesis COPD remains incompletely understood. The PI3K/Akt signaling pathway has recently emerged as critical regulator inflammation oxidative stre...

Chronic obstructive pulmonary disease (COPD) represents an increasing burden throughout the world. COPD-related mortality is probably underestimated because of the difficulties associated with identifying the precise cause of death. Respiratory failure is considered the major cause of death in advanced COPD. Comorbidities such as cardiovascular disease and lung cancer are also major causes and,...

overweight or obese with a body mass index (BMI) of 25 kg/m or more. Obesity is a major cause of morbidity; for example, in the United States in 2000 it was responsible for approximately 400 000 deaths and accounted for about 7% of health care expenditures. Obesity, particularly abdominal obesity, is a significant risk factor for cardiovascular disease, type 2 diabetes, rheumatoid arthritis and...

Introduction: More than 90% of the deaths caused by chronic obstructive pulmonary disease (COPD) occur in the low- and middle -income countries. The main aim of this study was to investigate the lipid profile levels in COPD patients and examine the correlation of total cholesterol, triglycerides, low-density lipoproteins, high density lipoproteins, and LDL/HDL risk ratio with COPD stages that a...

ABSTRACT This systematic review aimed to demonstrate the effectiveness of inspiratory muscle training (IMT) in people with chronic obstructive pulmonary disease (COPD), analyzing effects IMT on strength and endurance, exercise tolerance reduction dyspnea. A search was carried out PubMed, Cochrane Lilacs databases, from August 2021 February 2023, searching for studies published 2016. The descrip...
