  • Bronchodilators are the cornerstone of symptomatic chronic obstructive pulmonary disease (COPD) treatment. They are routinely recommended for symptom reduction, with a preference of long-acting over short-acting drugs. Bronchodilators are classified into two classes based on distinct modes of action, i.e., long-acting antimuscarinics (LAMA, once-daily and twice-daily), and long-acting ${\beta}2$-agonists (LABA, once-daily and twice-daily). In contrast to asthma management, evidence supports the efficacy of both classes of long-acting bronchodilators as monotherapy in preventing COPD exacerbations, with greater efficacy of LAMA drugs versus LABAs. Several novel LAMA/LABA fixed dose combination inhalers are currently approved for COPD maintenance treatment. These agents show superior symptom control to monotherapies, and some of these combinations have also demonstrated superior efficacy in exacerbation prevention versus monotherapies, or combinations of inhaled corticosteroids plus LABA. This review summarizes the current data on clinical effectiveness of bronchodilators alone or in combination to prevent exacerbations of COPD.

  • A cross-sectional study was conducted in an effort to investigate the effect of air pollution on respiratory symptoms. Two groups of female aged more than 20 living in the unpolluted rural area of Taebul (n=159) and urban area of Taegu (n=140) were selected. The ATS-DLD-78 questionnaire was translated into Korean and administered with minor modification. The proportion of smoker was less than 1% in both area. Exposure to smoking and higher educational level were more frequent in Taegu. Age-adjusted prevalence rates of 'chronic cough', 'chronic sputum', 'wheezing', and 'dyspnea' were higher in Taegu than in Taebul. In particular, the prevalence rate of 'chronic sputum' in Taegu was found to be higher, which was statistically significant. Exposure to smoking and education level were not concerned with all respiratory symptom prevalence rates. In conclusion, this study Indicates that an urban factor is related to the rates of respiratory symptoms in Korea.

  • Purpose: This study was conducted to examine the effects of the nurse-led one-on-one discharge education on the levels of symptom experience and self-care compliance among patients with chronic obstructive pulmonary disease (COPD) who had not previously participated in an education or respiratory rehabilitation program. Methods: This study used a quasi-experimental pre-and post-test design with nonequivalent control group. Sixty seven hospitalized patients (34 for experimental and 33 for control groups) were recruited from in-patient units of a general hospital from August to November, 2010. The one-on-one education session of symptom management and daily self-care was administered to experimental group for 50 minutes along with a follow-up phone call. Self-administered questionnaire was administered at the pretest and at 1 month after discharge. Results: The subjects were 67.43(${\pm}10.24$)years old in average. The mean differences of symptom experience (t=3.39, p=.001) and self-care compliance (t=-38.13, p<.001) in the experimental group was significantly higher than those of the control group. Conclusion: Nurse-led one-on-one discharge education was effective in reducing the level of symptom experience and enhancing self-care compliance at home within one month after discharge. Therefore, this form of one-on-one education provided by nurses might be applicable effectively for COPD patients who do not have access to respiratory rehabilitation programs.

  • The purpose of this study was to identify factors that influence the functional status of chronic lung disease patients. Method: A descriptive, correlational study design was used. The study was conducted at the outpatient respiratory clinic of the large university hospital in Korea. A convenience sample of 128 chronic lung patients (age = 64.2 yrs; 106 COPD, 17 bronchiectasis, 5 DILD) with mean FEV1 64.4 % predicted. Functional status was measured with SIP. Physical variables (FEV1% predicted, dyspnea, fatigue, pulmonary symptom distress), psychological variables (mood, stress), and situational variable (sleep quality) were examined. Dyspnea was measured by the BDI, fatigue was measured with the MFI. Mood was measured with the modified Korean version of POMS. Sleep quality was measured with the Pittsburgh Sleep Quality Index. Potential independent variables for the regression were age, gender, years since diagnosis, FEV1% predicted, dyspnea, fatigue, pulmonary symptom distress, stress, and sleep quality. Result: In general, functional status was relatively good. In regression analysis, functional status were significantly influenced by dyspnea, mood, age and fatigue. These variables explained 70 % of the variances in functional status. Conclusion: The results suggest that psychophysiologic symptom management should be a focus to enhance the functional status in this group.

  • The purpose of this study was to analyze the effect wool in patients with chronic obstructive pulmonary disease. The study was conducted experimentally on 53 patients with chronic obstructive pulmonary disease attending the chest diseases polyclinic of a hospital located in Erzurum. A randomized selection method was used to categorize patients into two groups; a treatment (n = 27), and a control group (n = 26). Patients in the treatment group (pre-test measurements were taken) wore wool vests for a period of three months, while patients in the control group wore cotton vests (placebo) for the same duration; post-test measurements were taken for both groups at the end of the three-month period. The Medical Outcomes Study Short Form 36, the St. George's Respiratory Questionnaire, and pulmonary function tests were used to collect data. Results concluded that there was a significant decrease (p < 0.05) in the overall score of the St. George's Respiratory Questionnaire, and the symptom, effect, and activity mean scores, while there was a significant increase (p < 0.05) in the SF-36 physical functioning, general health, bodily pain, role physical, vitality, role emotional, social functioning, mental health, physical and mental component summary mean scores of patients in the treatment group. Results of the study concluded that the symptoms, activity, disease effectiveness, and quality of life improved in patients that wore wool vests.

  • Background: The prevalence of small airway dysfunction (SAD) in patients with chronic obstructive pulmonary disease (COPD) across different ethnicities is poorly understood. This study aimed to estimate the prevalence of SAD in stable COPD patients. Methods: We conducted a cross-sectional study of 196 consecutive stable COPD patients. We measured pre- and post-bronchodilator (BD) lung function and respiratory impedance. The severity of COPD and lung function abnormalities was graded in accordance with the Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines. SAD was defined as either difference in whole-breath resistance at 5 and 19 Hz > upper limit of normal or respiratory system reactance at 5 Hz < lower limit of normal. Results: The cohort consisted of 95.9% men, with an average age of 66.3 years. The mean forced expiratory volume 1 second (FEV1) % predicted was 56.4%. The median COPD assessment test (CAT) scores were 14. The prevalence of post-BD SAD across the GOLD grades 1 to 4 was 14.3%, 51.1%, 91%, and 100%, respectively. The post-BD SAD and expiratory flow limitation at tidal breath (EFLT) were present in 62.8% (95% confidence interval [CI], 56.1 to 69.9) and 28.1% (95% CI, 21.9 to 34.2), respectively. COPD patients with SAD had higher CAT scores (15.5 vs. 12.8, p<0.01); poor lung function (FEV1% predicted 46.6% vs. 72.8%, p<0.01); lower diffusion capacity for CO (4.8 mmol/min/kPa vs. 5.6 mmol/min/kPa, p<0.01); hyperinflation (ratio of residual volume to total lung capacity % predicted: 159.7% vs. 129%, p<0.01), and shorter 6-minute walk distance (367.5 m vs. 390 m, p=0.02). Conclusion: SAD is present across all severities of COPD. The prevalence of SAD increases with disease severity. SAD is associated with poor lung function and higher symptom burden. Severe SAD is indicated by the presence of EFLT.

  • Purpose: The purpose of this study was to identify the factors influencing fatigue in patients with chronic obstructive pulmonary disease. Methods: A descriptive correlational study design was used. A convenience sample of 125 subjects was recruited from the outpatient respiratory clinic at a large university hospital. Data was collected from June to October, 2005 using structured questionnaires, an oxygen saturation test, a 6-minute walking test, and a pulmonary function test. Results: Subjects had a slightly low degree of fatigue. The fatigue showed a significant correlation with emotion(r=.589, p= .000), dyspnea(r=.304, p= .001), self-efficacy(r=-.278, p= .002), and symptom experience(r=.238, p= .008). Emotion(34.7%) and dyspnea(5.8%) were significant predictors to explain fatigue. Conclusion: This study provides comprehensive understanding of the influencing factors on fatigue in patients with chronic obstructive pulmonary disease. Nursing interventions to decrease negative emotion and dyspnea for management of fatigue is suggested.

  • Pulmonary paragonimiasis is the infectious disease of lung, due to 'Paragonimus westermani'. The clinical manifestations are various, and the main symptoms are chronic cough and persistent hemoptysis. Radiological findings mainly include thin walled cyst, migrating patch pulmonary infiltration, transient linear shadow, and hydropneumothorax, etc. The differential diagnosis should include pulmonary tuberculosis, pneumonia, other parasitic diseases, and rarely lung malignancy if the mass-like lesion is present. Recently, the incidence of paragonimiasis is very low. But the physicians should suspect paragonimus infection, if the patient has chronic respiratory symptom such as hemoptysis and lives in the endemic area such as Korea. A case of pulmonary paragonimiasis confirmed by histological basis of lung was presented with a review of the literature.
