Background/Aims: Most important cause of mortality in chronic obstructive pulmonary disease (COPD) patients is known to be cardiovascular disease (CVD). The objective of the present study was to evaluate the echocardiographic parameters in COPD patients with or without pre-diagnosed CVD and to inves..
Background/Aims: Inhaled corticosteroids (ICS) are a treatment of choice for eosinophilic airway diseases, but their efficacy for other causes of chronic cough is controversial.
Methods: We conducted a prospective observational study to determine the ICS efficacy and clinical predictors of response t..
Background/Aims: Associations between non-fasting triglyceride (TG) levels and a risk of ischemic heart disease (IHD) and cerebrovascular accident (CVA) have been suggested in Caucasians. We aimed to investigate whether non-fasting TG levels reflect the risk of IHD/CVA in Koreans.
Methods: We conduc..
Background/Aims: This study was conducted to evaluate the recent prevalence and trend of anti-tuberculosis (TB) drug resistance with a focus on multidrug-resistance (MDR) and fluoroquinolone resistance in South Korea.
Methods: We retrospectively reviewed the drug susceptibility testing results of c..
Background/Aims: Morphological changes due to lung disease in patients with cystic fibrosis (CF) were evaluated using high resolution computed tomography (HRCT), and the HRCT scores obtained using the Bhalla scoring system were correlated with those obtained using clinical and laboratory indicators...
Background/Aims: The relationship between nonpulmonary organ failure and the development of acute respiratory distress syndrome (ARDS) in patients with sepsis has not been well studied.
Methods: We retrospectively reviewed the medical records of patients with septic bacteremia admitted to the medic..
Background/Aims: Many systems including the cardiovascular system (ischemic heart diseases, heart failure, and hypertension) may act as comorbidities that can be seen during the course of chronic obstructive pulmonary disease (COPD). Comorbidities affect the severity and prognosis of COPD negatively..
Background/Aims: This study tested the hypothesis that prolonged low-dose cyclophosphamide (CTX) treatment after pulse therapy attenuate paraquat (PQ)-induced lung injury in rats.
Methods: PQ (25 mg/kg) was administered intraperitoneally to induce PQ-intoxicated rat model. The rats were randomly di..
Background/Aims: Vitamin D modulates innate and adaptive immune responses, and vitamin D deficiency is associated with increased mortality in hospitalized patients with pneumonia. We evaluated the prevalence of vitamin D deficiency in Korean patients with acute respiratory distress syndrome (ARDS) a..
Background/Aims: We explored the effects of intermittent normobaric hyperoxia alone or combined with chemotherapy on the growth, general morphology, oxidative stress, and apoptosis of benzo[a]pyrene (B[a]P)-induced lung tumors in mice.
Methods: Female A/J mice were given a single dose of B[a]P and ..
Background/Aims: Diffuse alveolar damage (DAD) is the histopathologic hallmark of acute respiratory distress syndrome (ARDS). However, there are several non-DAD conditions mimicking ARDS. The purpose of this study was to investigate the histopathologic heterogeneity of ARDS revealed by surgical lung..
Background/Aims: Brain and bone metastases are common in patients with lung cancer. The development of metastasis is associated with poor survival in lung cancer patients. Although tumor morphologic features on radiographs are routinely assessed for differentiation between benign and malignant lung ..
Background/Aims: Both diaphragmatic excursion and change in muscle thickening are measured using ultrasonography (US) to assess diaphragm function and mechanical ventilation weaning outcomes. However, which parameter can better predict successful extubation remains to be determined. The aim of this ..
Background/Aims: In patients with chronic obstructive pulmonary disease (COPD), the extent of physical activity (PA) is correlated with disease severity and prognosis. However, factors associated with low-level PA in elderly COPD patients are not known. We assessed the levels of PA and clinical fact..
Background/Aims: The use of extracorporeal membrane oxygenation (ECMO) is spreading rapidly, with successful procedures reported in the ECMO for Severe Adult Respiratory failure (CESAR) trial and treatment of the H1N1 pandemic. However, ECMO is associated with a high mortality rate. This study aimed..
Background/Aims: Despite increasing interest in pulmonary thromboembolism (PTE), data on recent trends in PTE incidence are limited. This study evaluated the recent incidence rate of PTE.
Methods: We performed a retrospective chart review of patients with PTE admitted to Chung-Ang University Hospit..
Background/Aims: Diesel exhaust particles (DEPs) lead to elevation of reactive oxygen species, which can activate the nucleotide-binding oligomerization domain-like receptor (NLR) family members containing the pyrin domain 3 (NLRP3)-inf lammasome. In this study, we elucidated whether NLRP3 -inf lamm..
Background/Aims: Pulmonary endarterectomy (PEA) is the gold standard for treating chronic thromboembolic pulmonary hypertension (CTEPH) in Western countries. The aim of this study was to investigate the long-term outcomes of performing PEA on CTEPH patients in comparison with medical therapy at a si..
Background/Aims: An association between reduced pulmonary function and diabetes has been observed. Our aim was to evaluate the prevalence and risk factors associated with reduced pulmonary function in diabetic patients.
Methods: We analyzed data from the Korea National Health and Nutrition Examinati..
Background/Aims: This study evaluated clinical characteristics and outcomes in very elderly (≥ 80 years of age) critical-ill patients admitted to a medical intensive care unit (MICU) in a regional single tertiary hospital.
Methods: We retrospectively evaluated prospectively collected data in the MI..
