The US health care system is rapidly adopting electronic records, which will dramatically increase the quantity of clinical data that are available electronically. Simultaneously, rapid progress has been made in analytics—techniques for analyzing large quantities and gleaning new insights from analysis—which part what known as big . As a result, there unprecedented opportunities to use reduce costs United States. We present six cases—that is, key examples—where some clearest exist through...
The vertebrate retina is comprised of seven major cell types that are generated in overlapping but well-defined intervals. To identify genes might regulate retinal development, gene expression the developing was profiled at multiple time points using serial analysis (SAGE). patterns 1,051 showed developmentally dynamic by SAGE were investigated situ hybridization. A molecular atlas and mature thereby constructed, along with a taxonomic classification developmental patterns. Genes identified...
[corrected] The existence of several technologies for measuring gene expression makes the question cross-technology agreement measurements an important issue. Cross-platform utilization data from different has potential to reduce need duplicate experiments but requires corresponding be comparable.A comparison mRNA 2895 sequence-matched genes in 56 cell lines standard panel 60 cancer National Cancer Institute (NCI 60) was carried out by calculating correlation between matched and concordance...
Abstract To metastasize, carcinoma cells must attenuate cell–cell adhesion to disseminate into distant organs. A group of transcription factors, including Twist1, Snail1, Snail2, ZEB1, and ZEB2, have been shown induce epithelial mesenchymal transition (EMT), thus promoting tumor dissemination. However, it is unknown whether these factors function independently or coordinately activate the EMT program. Here we report that direct induction Snail2 essential for Twist1 EMT. knockdown completely...

Cross-institutional healthcare predictive modeling can accelerate research and facilitate quality improvement initiatives, thus is important for national delivery priorities. For example, a model that predicts risk of re-admission particular set patients will be more generalizable if developed with data from multiple institutions. While privacy-protecting methods to build models exist, most are based on centralized architecture, which presents security robustness vulnerabilities such as...
Background. Acute kidney injury (AKI) is common in critically ill patients and associated with high morbidity mortality. Early identification of high-risk provides an opportunity to develop strategies for prevention, early diagnosis treatment AKI. Methods. We undertook this multicenter prospective cohort study validate a risk score predicting AKI admitted intensive care unit (ICU). Patients were screened predictor variables within 48 h ICU admission. Baseline acute factors recorded at the...

Abstract Background and Aims Early diagnosis of aortic stenosis (AS) is critical to prevent morbidity mortality but requires skilled examination with Doppler imaging. This study reports the development validation a novel deep learning model that relies on two-dimensional (2D) parasternal long axis videos from transthoracic echocardiography without imaging identify severe AS, suitable for point-of-care ultrasonography.

Objective: To allow exchange of clinical practice guidelines among institutions and computer-based applications.
Objective: Predictive models that generate individualized estimates for medically relevant outcomes are playing increasing roles in clinical care and translational research. However, current methods calibrating these lose valuable information. Our goal is to develop a new calibration method conserve as much information possible, would compare favorably existing terms of important performance measures: discrimination calibration. Material methods: We propose an adaptive technique utilizes...
Objective The classification of complex or rare patterns in clinical and genomic data requires the availability a large, labeled patient set. While methods that operate on centralized sources have been extensively used, little attention has paid to understanding whether models such as binary logistic regression (LR) can be developed distributed manner, allowing researchers share without necessarily sharing data. Material Instead bringing central repository for computation, we bring...
