INTRODUCTION: Chronic parodontitis is a prevalent oral disease that may lead to the loss of teeth independently of caries. Some systemic diseases (e.g., diabetes mellitus, chronic renal failure) may aggravate chronic parodontitis. On the other hand, this oral disease may aggravate other systemic diseases. Earlier studies suggested a correlation between chronic parodontitis and very severe chronic obstructive pulmonary disease (COPD). AIM: The aim of our study was the investigation of the correlation between chronic parodontitis and chronic obstructive pulmonary disease...

BACKGROUND: Information on causes of death (COD) is crucial for measuring the health outcomes of populations and progress towards the Sustainable Development Goals. In many countries such as Vietnam where the civil registration and vital statistics (CRVS) system is dysfunctional, information on vital events will continue to rely on verbal autopsy (VA) methods. This study assesses the validity of VA methods used in Vietnam, and provides recommendations on methods for implementing VA validation studies in Vietnam...

OBJECTIVES: International guidelines recommend the use of long-acting bronchodilators for the treatment of chronic obstructive pulmonary disease (COPD), but the usefulness of short-acting bronchodilator assist use for stable COPD remains uncertain. The purpose of the present study was to objectively demonstrate the effects of assist use of procaterol, a short-acting -agonist, on the respiratory mechanics of stable COPD patients treated with a long-acting bronchodilator using forced oscillation technique (FOT) and conventional spirometry...

Introduction: Exposure to secondhand smoke (SHS) is associated with occult obstructive lung disease as evident by abnormal airflow indices representing small airway disease despite having preserved spirometry (normal forced expiratory volume in 1 s-to-forced vital capacity ratio, FEV1 /FVC). The significance of lung volumes that reflect air trapping in the presence of preserved spirometry is unclear. Methods: To investigate whether lung volumes representing air trapping could determine susceptibility to respiratory morbidity in people with SHS exposure but without spirometric chronic obstructive pulmonary disease, we examined a cohort of 256 subjects with prolonged occupational SHS exposure and preserved spirometry...

Aim: Six-minute walking test distance (6MWD) and body mass index, obstruction, dyspnea and exercise (BODE) index are measures of functional status in COPD patients, but require space, time and patient's compliance. Exhaled volatile organic compounds (VOCs) analysis via electronic nose is a quick and easy method that has already been used to discriminate COPD phenotypes. The aim of this study is to evaluate whether VOCs analysis can predict functional status and its variation over time in COPD patients...

Introduction: There is a growing clinical awareness about the influence of gut-lung axis on lung injury and coexisting manifestations of disease processes in both the intestine and lungs. Patients of chronic lung diseases such as chronic obstructive pulmonary disease (COPD) and asthma very often present with coexistent gut symptoms. In the present study, we have tried to establish the correlation of severity of pulmonary pathology of COPD and asthma patients with functional gastrointestinal (GI) symptoms of the patients...

RATIONALE: Previous studies have suggested that acute exacerbations of COPD may be associated with increased risk of myocardial infarction and ischaemic stroke. OBJECTIVE: We aimed to quantify the increased risks of myocardial infarction and ischemic stroke risk associated with both moderate and severe acute exacerbation, and to investigate factors which may modify these risks. METHODS: We performed a self-controlled case-series to investigate the rates of myocardial infarction and ischemic stroke following acute exacerbation compared to stable time, within individuals...

The coexistence of chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea syndrome in a single patient is known as "overlap syndrome," and worsens the prognosis of the affected subjects. A marked bronchodilation may be useful for the treatment of this condition. In fact, as stated in the GOLD 2017 guidelines, the combination of indacaterol/glycopyrronium may exert positive synergistic effects on smooth muscle cell and airway resistance, with a more pronounced efficiency in reducing lung hyperinflation...

Ischemic heart disease (IHD) is a frequent accompaniment of chronic obstructive pulmonary disease (COPD). Co-occurrence of these two diseases is associated with many risk factors, difficulties in implementing appropriate therapies, numerous complications, and high spending for treatment. All these elements significantly reduce the quality of life of patients. The aim of this study was to estimate the expenditure for medications involved with IHD pharmacotherapy in the course of COPD. This retrospective study was based on the review of medical files of 57 patients, 27 women and 30 men, diagnosed with IHD, according to the severity classification, in the course of COPD which was staged according to the GOLD criteria...

RATIONALE: The Global Initiative for Chronic Obstructive Lung Disease criteria require a ratio of forced expiratory volume in 1 second (FEV1 ) to forced vital capacity (FVC) (FEV1 /FVC) of less than 0.70 for the diagnosis of chronic obstructive pulmonary disease, whereas other criteria emphasize a lower limit of normal approach. However, the use of Global Initiative for Chronic Obstructive Lung Disease (or lower limit of normal) criteria may result in classification of many smokers with respiratory morbidities as not having chronic obstructive pulmonary disease...

Background: Severe exacerbations and mortality are major outcomes in COPD, and risk factors for these events are actively searched for. Several predictors of mortality have been identified in COPD. The inspiratory capacity/total lung capacity (IC/TLC) ratio has been shown to be a strong predictor of all cause and respiratory mortality in patients with COPD. The major objectives of this study were to analyze which clinical parameters, including lung volumes, were the best predictors of the 5-year cumulative risk of hospital admissions or death and the 5-year risk of exacerbations, in stable COPD patients...

PURPOSE: Some patients with chronic obstructive pulmonary disease (COPD) fail to achieve health benefits with pulmonary rehabilitation (PR). Exercise intensity and load represent stimulus for adaptation but it is unclear whether inappropriate exercise intensity and/or load are affected by severity of COPD, which may affect health benefits. The purpose was to determine whether COPD severity and/or the severity of pulmonary limitation to exercise (PLE) impacted exercising intensity or load and whether resultant intensity/load affected health outcomes derived from PR...
