Masked image modeling (MIM) with transformer backbones has recently been exploited as a powerful self-supervised pre-training technique. The existing MIM methods adopt the strategy to mask random patches of and reconstruct missing pixels, which only considers semantic information at lower level, causes long time. This paper presents HybridMIM, novel hybrid learning method based on masked for 3D medical segmentation. Specifically, we design two-level masking hierarchy specify how in...

This article discusses analysis, approach, outcomes complications BAE hemoptysis.A retrospective analysis 344 cases, who underwent bronchial arteriography at Tianjin Haihe...

An increasing number of patients infected with nontuberculous mycobacteria (NTM) are observed worldwide. However, it is challenging to identify NTM lung diseases from pulmonary tuberculosis (PTB) due considerable overlap in classic manifestations and clinical radiographic characteristics. This study quantifies both cavitary bronchiectasis regions CT images explores a machine learning approach for the differentiation PTB. It involves 116 103 quantitative features. After selection informative...

The increasing global incidence of nontuberculous mycobacterial (NTM) pulmonary disease highlights the need for rapid diagnostic methods to guide timely treatment and prevent antibiotic misuse. While bacterial culture remains gold standard diagnosis, its extended turnaround time compromises clinical decision-making. Computed tomography (CT), with high sensitivity lung lesions imaging capabilities, has emerged as a critical tool. AI-assisted CT interpretation shows particular promise...

Abnormal lesion patterns (ground-glass opacity, consolidation, parenchymal bands, air trapping,...

Hyperphosphatemia is a common complication of late-stage chronic kidney disease (CKD). Nicotinamide (NAM) has been reported as an adjunctive therapy for hyperphosphatasemia, but the effect NAM on fibroblast growth factor 23 (FGF23) and Klotho rarely reported.We randomly assigned 98 patients who underwent regular hemodialysis to received (0.5-1.5 g per day, or 1-3 tablets day) placebo (1-3 add-on calcium-based phosphorus binders in 1:1 ratio. All enrollments were followed-up 52 weeks. We...

COVID-19 is a new acute respiratory infectious disease caused by novel Coronavirus (2019-COV-2) infection. On November 26, 2021, the World Health Organization announced 2019-COV-2 variant strain Omicron (B.1.1.529). Omicron's emergence added further uncertainty to outbreak. Here we report first case infected with in China, 17-year-old female student. In this paper, clinical symptoms, laboratory and imaging examinations treatment of Omicron-infected patient China were analyzed. This might...

There is limited information describing the course and severity of illness in subjects infected by severe acute respiratory syndrome coronavirus 2 Omicron variant, especially children. In this population-based cohort study, with variant infection during outbreak between January 8 February 12, 2022 Tianjin, China were included (n = 429). The main outcomes distribution asymptomatic, mild, moderate, patients, clinical courses including interval from positive polymerase chain reaction (PCR) test...

COVID-19 is a kind of pneumonia with new coronavirus infection, and the risk death in patients diabetes four times higher than that healthy people. It unclear whether there difference chest CT images between type 2 mellitus (T2DM) non-diabetes (NDM) patients. The aim this study was to investigate differences T2DM NDM based on quantitative method artificial intelligence. A total 62 were retrospectively enrolled divided into group (T2DM group, n = 15) B (NDM 47). clinical laboratory...

The emergence of the severe acute respiratory syndrome coronavirus 2 omicron variant has been triggering new wave disease 2019 (COVID-19) globally. However, risk factors and outcomes for radiological abnormalities in early convalescent stage (1 month after diagnosis) infected patients are still unknown.Patients were retrospectively enrolled if they admitted to hospital due COVID-19. chest computed tomography (CT) images clinical data obtained at baseline (at time first CT image that showed 1...

Nontuberculous mycobacterial lung disease (NTM-LD) and Mycobacterium tuberculosis (MTB-LD) are difficult to distinguish based on conventional imaging examinations. In recent years, radiomics has been used discriminate them. However, existing radiomic methods mainly focus specific lesion types, have limitations in handling the presence of multiple types that vary among different patients. We aimed establish a model patient's CT scans, analyzed importance distinguishing two diseases. 120...
