On the Evaluation of Surrogate Markers in Real World Data Settings [PDF]
Shortcomings of randomized clinical trials are pronounced in urgent health crises, when rapid identification of effective treatments is critical. Leveraging short-term surrogates in real-world data (RWD) can guide policymakers evaluating new treatments.

ULCERATIVE COLITIS IN CHILDREN [PDF]
Chronic nonspecific ulcerative colitis remaine a disease of unkown etiology, although much new information continues to be gleaned from basic research and clinical trials. In most instances, ulcerative colitis respond to medical therapy.

Deep Bayesian Active-Learning-to-Rank for Endoscopic Image Data [PDF]
Automatic image-based disease severity estimation generally uses discrete (i.e., quantized) severity labels. Annotating discrete labels is often difficult due to the images with ambiguous severity. An easier alternative is to use relative annotation, which compares the severity level between image pairs.

Disease Severity Regression with Continuous Data Augmentation [PDF]
Disease severity regression by a convolutional neural network (CNN) for medical images requires a sufficient number of image samples labeled with severity levels. Conditional generative adversarial network (cGAN)-based data augmentation (DA) is a possible solution, but it encounters two issues.

Integrative computational approach identifies immune‐relevant biomarkers in ulcerative colitis
Ulcerative colitis is a common inflammatory bowel disease with a complex genetic and immune etiology. Immune infiltration plays a vital role in the development of ulcerative colitis.

Gastrointestinal Mucosal Problems Classification with Deep Learning [PDF]
Gastrointestinal mucosal changes can cause cancers after some years and early diagnosing them can be very useful to prevent cancers and early treatment. In this article, 8 classes of mucosal changes and anatomical landmarks including Polyps, Ulcerative Colitis, Esophagitis, Normal Z-Line, Normal Pylorus, Normal Cecum, Dyed Lifted Polyps, and Dyed ...

DNA methylation-associated colonic mucosal immune and defense responses in treatment-naïve pediatric ulcerative colitis [PDF]
Inflammatory bowel diseases (IBD) are emerging globally, indicating that environmental factors may be important in their pathogenesis. Colonic mucosal epigenetic changes, such as DNA methylation, can occur in response to the environment and have been ...

Combined Hepatic and Splenic Abscesses in a Patient with Ulcerative Colitis [PDF]
Liver abscesses are very rare complications of ulcerative colitis, and furthermore, there has been only one case of splenic abscess in a patient with ulcerative colitis reported in the English literature. We recently encountered a patient with ulcerative

Histologic Features with Predictive Value for Outcome of Patients with Ulcerative Colitis [PDF]
Ulcerative colitis is an inflammatory bowel disease with variable evolution, in which is difficult to establish patient’s outcome. Histology is an important part of diagnosis of ulcerative colitis and has an increasing role in patients’ management, since
