In this study, we evaluated the efficacy of discharge Acute Physiology and Chronic Health Evaluation (APACHE) II score in predicting post-intensive care unit (ICU) mortality ICU readmission during same hospitalisation a surgical ICU. Of 1190 patients who were admitted to stayed >48 hours between October 2007 March 2010, 23 (1.9%) died 86 (7.2%) readmitted after initial discharge, with 26 (3.0%) within 48 hours. The area under receiver operating characteristics curve admission APACHE scores...
Rationale: Because the prognosis of nontuberculous mycobacterial pulmonary disease varies, a scoring system predicting mortality is needed.Objectives: We aimed to develop novel predict among patients with disease.Methods: included age ≥20 years newly diagnosed disease, Mycobacterium avium, M. intracellulare, abscessus subsp. abscessus, or massiliense. Cox proportional hazards models were used identify predictors in derivation cohort, and was developed. It validated an independent prospective...
Background The factors affecting radiologists' diagnostic determinations in artificial intelligence (AI)-assisted image reading remain underexplored. Purpose To assess how AI performance and reader characteristics influence detection of malignant lung nodules during AI-assisted chest radiographs. Materials Methods This retrospective study consisted two sessions from April 2021 to June 2021. Based on the first session without assistance, 30 readers were assigned into groups with equivalent...
Objective:To analyze the complications of percutaneous transthoracic needle biopsy using CT-based imaging modalities for guidance in comparison with fluoroscopy a large retrospective cohort.Materials and Methods: This study was approved by multiple Institutional Review Boards requirement informed consent waived.We retrospectively included 10568 biopsies from eight referral hospitals 2010 through 2014.In univariate multivariate logistic analyses, 3 (CT, CT fluoroscopy, cone-beam CT) were...
Background Few studies have compared abbreviated breast MRI with full-protocol in women a personal history of cancer (PHBC), and they not adjusted for confounding variables. Purpose To compare PHBC by using propensity score matching to adjust Materials Methods In this single-center retrospective study, who underwent (January 2008-August 2017) or (September 2017-April 2019) were identified. With use score-matched cohort, screening performances between the two groups McNemar test...
To evaluate the correlation between single- and multi-slice cross-sectional thoracolumbar whole-body compositions.We retrospectively included patients who underwent PET-CT scans from January 2016 to December 2019 at multiple institutions. A priori-developed, deep learning-based commercially available 3D U-Net segmentation provided reference volumes 2D areas of muscle, visceral fat, subcutaneous fat upper, middle, lower endplate individual T1-L5 vertebrae. In derivation set, we analyzed...
As the associations between pediatric overweight/obesity and bone health remain controversial, we investigated effects of as well lean mass (LM) fat (FM) on parameters in adolescents. Bone were evaluated using dual-energy X-ray absorptiometry (DXA) data 982 adolescents (aged 12-19 years) from Korea National Health Nutrition Examination Survey (2009-2010). Z-scores for LM, FM, mass, mineral density (BMD), apparent (BMAD) Korean reference values used analysis. Adolescents with had...
To evaluate the prevalence of vitamin D deficiency and predictors for low status in Korean adolescents living between latitudes 33° 39° N.A descriptive cross-sectional study.Korea National Health Nutrition Examination Survey (KNHANES) 2008-2009.A total 1510 healthy aged 12-18 years (806 male, mean age 14.7 years) participated. Possible (log-transformed 25-hydroxyvitamin (25(OH)D) concentrations) were evaluated.The (25(OH)D<20 ng/ml) was 89.1% spring, 53.7% summer, 63.9% autumn 90.5% winter....

White-box cryptography presented by Chow et al. is an obfuscation technique for protecting secret keys in software implementations even if adversary has full access to the implementation of encryption algorithm and control over its execution platforms. Despite practical importance, progress not been substantial. In fact, it repeated that as a proposal whitebox reported, attack lower complexity soon announced. This mainly because most cryptanalytic methods target specific implementations,...
Abstract Physicians often encounter surgical candidates with lumbar disc herniation (LDH) who request non-surgical management even though surgery is recommended. However, second opinions may differ among doctors. Therefore, a prospective comprehensive cohort study (CCS) was designed to assess outcomes of nonsurgical treatment for were recommended undergo LDH but requested opinion. The CCS includes both randomized and observational cohorts, comprising nonsurgery cohort, in parallel fashion....
