Rationale: The role of viruses in pneumonia adults and the impact viral infection on mortality have not been elucidated. Previous studies significant limitations that they relied predominantly upper respiratory specimens.Objectives: To investigate adult patients with requiring intensive care unit (ICU) admission.Methods: A retrospective analysis a prospective cohort was conducted 28-bed medical ICU. Patients severe community-acquired (CAP) or healthcare-associated (HCAP) were included...
Background Intratumor heterogeneity in lung cancer may influence outcomes. CT radiomics seeks to assess tumor features provide detailed imaging features. However, radiomic vary according the reconstruction kernel used for image generation. Purpose To investigate effect of different kernels on and whether conversion using a convolutional neural network (CNN) could improve reproducibility between kernels. Materials Methods In this retrospective analysis, patients underwent non–contrast...
Artificial intelligence (AI) is expected to affect various fields of medicine substantially and has the potential improve many aspects healthcare. However, AI been creating much hype, too. In applying technology patients, medical professionals should be able resolve any anxiety, confusion, questions that patients public may have. Also, they are responsible for ensuring becomes a beneficial patient care. These make acquisition sound knowledge experience about task high importance students....
Background: In lung adenocarcinomas manifesting as part-solid lesions, evidence supports greater prognostic importance for the volume of solid component than whole nodule. However, assessments lesion growth rates have historically focused on doubling time (VDT) lesion. Objective: To compare utility VDT versus resected lesions chest CT. Methods: This retrospective study included 122 patients (mean age, 64.0 ± 8.2years; 53 men, 69 women) with adenocarcinoma a who underwent at least two...
Rationale: Beginning in 2006, epidemics of a fatal lung injury unknown cause children were observed Korea every spring. A recent study demonstrated that this type children's interstitial disease (chILD) is associated with humidifier disinfectant use.Objectives: To determine the clinical characteristics chILD and to assess whether nationwide suspension sales autumn 2011 affected its incidence.Methods: The suspected cases between 2006 determined by retrospective study. potential causal...
Background Viral pathogens have not generally been regarded as important causes of severe hospital-acquired pneumonia (HAP), except in patients with hematologic malignancy or transplant recipients. We investigated the role and distribution viruses adult HAP who required intensive care. Methods From March 2010 to February 2012, admission care unit (ICU), 28-bed medical ICU a tertiary hospital, were prospectively enrolled. Respiratory detected using multiplex reverse-transcription polymerase...
<h3>Background</h3> In April 2011 a tertiary hospital in Seoul, Korea reported several cases of severe respiratory distress unknown origin young adults. <h3>Methods</h3> To find the route transmission, causative agent and patient risk factors outbreak, an investigation epidemic was initiated. Clinicopathological conferences led to suspicion that related inhalation injury. An age- sex-matched case–control study therefore performed examine exposure patients various agents. <h3>Results</h3> Of...
<h3>Background</h3> Over a few months in the spring of 2011, cluster patients with severe respiratory distress were admitted to our intensive care unit (ICU). Household clustering was also observed. Extensive laboratory investigations failed detect an infectious cause. <h3>Methods</h3> Clinical, radiological and pathological conducted Korean Center for Disease Control performed epidemiological studies. <h3>Results</h3> The case series consisted 17 patients. Their median age 35 (range 28–49)...
Humidifier disinfectant lung injury is an acute disease attributed to recurrent inhalation of certain aerosols emitted from room humidifiers. An outbreak this toxic occurred in South Korea 1995 until all humidifier products were recalled the consumer market by government 2011.A nationwide study was conducted ascertain and classify potential cases assess dose-response relationships.By several mechanisms, clinicians general public invited report suspected health officials Korea. A committee...
The occurrence of numerous cases interstitial lung disease in children (chILD) every spring Korea starting 2006 raised suspicion about a causal relationship with the use humidifier disinfectants (HDs). aim this study was to evaluate association between HD and risk chILD.This retrospective, 1∶3 matched case-control consisted 16 chILD that had developed 2010 2011. three groups parallel controls (patients acute lobar pneumonia, asthma, healthy children) were by age, gender, index date....
To retrospectively assess the effect of CT slice thickness on reproducibility radiomic features (RFs) lung cancer, and to investigate whether convolutional neural network (CNN)-based super-resolution (SR) algorithms can improve RFs obtained from images with different thicknesses.CT 1-, 3-, 5-mm thicknesses 100 pathologically proven cancers between July 2017 December were evaluated. CNN-based SR using residual learning developed convert thick-slice into 1-mm slices. Lung semi-automatically...
Rationale: The optimal follow-up computed tomography (CT) interval for detecting the progression of interstitial lung abnormality (ILA) is unknown. Objectives: To identify strategies and extent thresholds on CT relevant to outcomes. Methods: This retrospective study included self-referred screening participants aged 50 years or older, including nonsmokers, who had imaging findings ILA chest scans. Consecutive scans were evaluated determine dates initial showing progression. Deep...
Background The volume doubling time (VDT) is a key parameter in the differentiation of aggressive tumors from slow-growing tumors. How different histologic subtypes primary lung adenocarcinomas vary their VDT and prognostic value this measurement unknown. Purpose To investigate differences between predominant to assess correlation prognosis. Materials Methods This retrospective study included patients who underwent at least two serial CT examinations before undergoing operation July 2010...
Objective:The aim of our study was to develop and validate a convolutional neural network (CNN) architecture convert CT images reconstructed with one kernel different reconstruction kernels without using sinogram.Materials Methods: This retrospective approved by the Institutional Review Board.Ten chest scans were performed B10f, B30f, B50f, B70f kernels.The dataset divided into six, two, two examinations for training, validation, testing, respectively.We constructed CNN consisting six...
