There have been few large-scale studies on the relationship between smoking and gut microbiota. We investigated status composition of This was a population-based cross-sectional study using Healthcare Screening Center cohort data. A total 758 men were selected divided into three groups: never (n = 288), former 267), current smokers 203). Among groups, there no difference in alpha diversity, however, Jaccard-based beta diversity showed significant (p 0.015). Pairwise permutational...
Background: Little information is available regarding medical utilization and cost in patients with overlap syndrome of chronic obstructive pulmonary disease (COPD) asthma. The purpose this study to analyze compare them COPD without Methods: Using the 2009 Korean National Health Insurance (NHI) database, were identified. Medical costs also analyzed. Results: Of a total 185,147 identified COPD, 101,004 classified asthma 84,143 In 2009, percentages emergency room visits, admissions, intensive...
The purpose of this study is to assess the image quality and radiation dose reduction ultra-low-dose CT using sinogram-affirmed iterative reconstruction (SAFIRE).This prospective enrolled 25 patients who underwent three consecutive unenhanced scans including low-dose (120 kVp 30 mAs) two protocols (protocol A, 100 20 mAs; protocol B, 80 with SAFIRE. were assessed.The mean (± SD) effective was 1.06 ± 0.11, 0.44 0.05, 0.31 0.03 mSv for CT, respectively. Overall determined as diagnostic in 100%...
Chronic bronchitis (CB) has been related to poor outcomes in Obstructive Pulmonary Disease (COPD). From a clinical standpoint, we have shown that subjects with CB group moderate severe airflow obstruction were younger, more likely be current smokers, male, Caucasian, had worse health quality of life, dyspnea, and increased exacerbation history compared those without CB. We sought further refine our characterization chronic bronchitics larger cohort analyze the CT correlates COPD subjects....
Abstract Background Gastroesophageal reflux disease (GERD) is one of the most common causes chronic cough and a potential risk factor for exacerbation obstructive pulmonary (COPD). The aim this study was to investigate prevalence factors GERD in patients with COPD association between exacerbation. Methods Data were collected from National Health Insurance Database Korea. subjects 40 years old older, who had as primary or secondary diagnosis codes utilized health care resource receive...
Multicentre study.To define the clinical characteristics of patients with tuberculosis (TB) destroyed lung due to past TB.We reviewed TB-destroyed between May 2005 and June 2011.A total 595 from 21 hospitals were enrolled. The mean age was 65.63 ± 0.47 (mean standard error); 60.5% male. number lobes involved 2.59 0.05. Pleural thickening observed in 54.1% patients. Mean forced vital capacity (FVC), expiratory volume 1 s (FEV(1)), FEV(1)/FVC, bronchodilator response exacerbations per year...
The Korea Chronic Obstructive Pulmonary Disorders Subgroup Study Team (Korea COPD team, KOCOSS) is a multicenter observational study that includes 956 patients (mean age 69.9 ± 7.8 years) who were enrolled from 45 tertiary and university-affiliated hospitals December 2011 to October 2014. initial evaluation for all included pulmonary function tests (PFT), 6-minute walk distance (6MWD), Assessment Test (CAT), modified Medical Research Council (mMRC) dyspnea scale, the COPD-specific version of...
Abstract Conventional deep learning (DL) algorithm requires full supervision of annotating the region interest (ROI) that is laborious and often biased. We aimed to develop a weakly-supervised DL diagnosis breast cancer at ultrasound without image annotation. Weakly-supervised algorithms were implemented with three networks (VGG16, ResNet34, GoogLeNet) trained using 1000 unannotated US images (500 benign 500 malignant masses). Two sets 200 (100 100 masses) used for internal external...
In Brief Purpose: To estimate posttraumatic enophthalmos using computer-based volume measurement of the orbital fracture to provide information on surgical guidelines. Methods: The wall fractures in 35 patients who did not undergo surgery was measured a Rapidia work station system. Hertel ophthalmometry, diplopia, and ocular motility were investigated. measurements relative intact contralateral orbit correlated with enophthalmos, motility. Patients examined at initial visit, then 1 week,...
Background/Aims Patients with chronic airway lung diseases often experience depression and anxiety, but little information is available regarding Koreans these conditions. We thus assessed anxiety in Korean patients diseases. Methods The degree of 84 outpatients obstructive pulmonary disease (COPD), 37 asthma, 33 bronchiectasis, 73 healthy controls were evaluated by the Beck Depression Inventory (BDI) State-Trait Anxiety (STAI). Results COPD bronchiectasis had higher BDI scores more likely...
Background: Patients with high grade chronic pulmonary obstructive disease (COPD) account for much of the COPD-related mortality and incur excessive financial burdens medical care utilization. We aimed to determine characteristics use such patients using nationwide data from Korean Health Insurance Review Assessment Service in 2009. Materials methods: COPD were identified by searching International Classification Diseases–10th Revision those medication. selected based on their patterns...
The clinical course of idiopathic pulmonary fibrosis (IPF) varies widely. Although the GAP model is useful for predicting mortality, survivals have not yet been validated each score. We aimed to elucidate how prognosis related score and stage in IPF patients. Korean Interstitial Lung Disease Study Group conducted a national survey evaluate various characteristics patients from 2003 2007. Patients were diagnosed according 2002 criteria ATS/ERS. enrolled 1,685 with IPF; 1,262 had undergone...
Background and objective: Overlap syndrome shares features of both asthma chronic obstructive pulmonary disease (COPD). The aim this study was to investigate characteristics overlap their effect on self-rated health (SRH). Methods: We analyzed data from the Fourth Korea National Health Nutrition Examination Survey 2007–2009. Subjects with acceptable spirometry available wheezing history were included. classified into four groups based forced expiratory volume in one second (FEV 1 )/forced...
Since the Global Initiative for Chronic Obstructive Lung Disease (GOLD) groups A-D were introduced, lung function changes according to group have been evaluated rarely.We investigated rate of decline in annual patients categorized 2014 GOLD guidelines.Patients with COPD included Korean (KOLD) prospective study, who underwent yearly postbronchodilator spirometry at least three times, included. The main outcome was forced expiratory volume 1 second (FEV1), which analyzed by random-slope and...
Chronic obstructive pulmonary disease (COPD) patients include those who have never smoked. However, risk factors other than smoking in never-smokers not been elucidated sufficiently. This study investigated the for COPD among Korea using population-based data.The data were retrieved from Korean National Health and Nutrition Survey IV conducted 2007 to 2009. Among subjects aged 40 years or older underwent appropriate function tests, diagnosed with asthma showing a restrictive pattern on tests...
Adenocarcinoma is the most common type of non-small cell lung cancer. Some causative genomic alterations in epidermal growth factor receptor (EGFR), including deletions exon 19 (E19 dels) and a point mutation E21, are known to have favourable prognoses due sensitivity tyrosine kinase inhibitors; however, other uncommon mutations unclear. This study analysed clinical significance EGFR types adenocarcinoma. We retrospectively reviewed 1,020 subjects (mean age: 66.8 years, female: 41.7%) who...
