Deriving disease subtypes from electronic health records (EHRs) can guide next-generation personalized medicine. However, challenges in summarizing and representing patient data prevent widespread practice of scalable EHR-based stratification analysis. Here we present an unsupervised framework based on deep learning to process heterogeneous EHRs derive representations that efficiently effectively enable at scale. We considered 1,608,741 patients a diverse hospital cohort comprising total...

This study sought to develop DL models capable of comprehensively quantifying left and right ventricular dysfunction from ECG data in a large, diverse population. Rapid evaluation function using deep learning (DL) on electrocardiograms (ECGs) can assist diagnostic workflow. However, tools estimate (RV) do not exist, whereas those (LV) are restricted quantification very low LV only.

Abstract A major goal of precision medicine is to predict prognosis based on individualized information at the earliest possible points in development. Using early snapshots adaptive functioning and unsupervised data-driven discovery methods, we uncover highly stable autism subtypes that yield relevant later prognosis. Data from National Institute Mental Health Archive (NDA) ( n = 1,098) was used three (<72 months) generalize with 96% accuracy. Outcome data NDA 2,561; mean age, 13 years)...

Abstract Objectives Social support (SS) and social isolation (SI) are determinants of health (SDOH) associated with psychiatric outcomes. In electronic records (EHRs), individual-level SS/SI is typically documented in narrative clinical notes rather than as structured coded data. Natural language processing (NLP) algorithms can automate the otherwise labor-intensive process extraction such information.

Abstract Social-communication (SC) and restricted repetitive behaviors (RRB) are autism diagnostic symptom domains. SC RRB severity can markedly differ within between individuals may be underpinned by different neural circuitry genetic mechanisms. Modeling SC-RRB balance could help identify how mechanisms map onto such phenotypic heterogeneity. Here, we developed a stratification model that makes highly accurate (97–99%) out-of-sample = RRB, > subtype predictions. Applying this to resting...

The recognition of emotional body movement (BM) is impaired in individuals with Autistic Spectrum Disorder ASD, yet it not clear whether the difficulty related to encoding motion, emotions, or both. Besides, BM has been traditionally studied using point-light displays stimuli (PLDs) and still underexplored ASD intellectual disability (ID).

Abstract Early detection and intervention are believed to be key facilitating better outcomes in children with autism, yet the impact of age at treatment start on outcome is poorly understood. While clinical traits such as language ability have been shown predict outcome, whether or not how information genomic level can unknown.

Abstract Early motor difficulties are a common in many, but not all, autistic individuals. These tend to be highly present individuals carrying rare genetic mutations with high penetrance for autism. Many of these mechanisms also cause neurophysiological dysregulation excitation-inhibition balance (E:I). A predicted downstream consequence E:I imbalance circuitry would translate behaviorally into enhanced ‘motor noise’ – that is, increased variability execution actions. Here we tested the...

Convolutional Neural Networks (CNNs) are a popular deep learning architecture widely applied in different domains, particular classifying over images, for which the concept of convolution with filter comes naturally. Unfortunately, requirement distance (or, at least, neighbourhood function) input feature space has so far prevented its direct use on data types such as omics data. However, number metrizable, i.e., they can be endowed metric structure, enabling to adopt convolutional based...

Clinical note classification is a common clinical NLP task. However, annotated data-sets are scarse. Prompt-based learning has recently emerged as an effective method to adapt pre-trained models for text using only few training examples. A critical component of prompt design the definition template (i.e. text). The effect position, however, been insufficiently investigated. This seems particularly important in setting, where task-relevant information usually sparse notes. In this study we...

Despite being a unique source of information on patients' status and disease progression, clinical notes are characterized by high levels duplication redundancy. In general domain text, it has been shown that deduplication does not harm language model (LM) pretraining, thus helping reduce the training cost. Although large LMs have proven to learn medical knowledge, they still require specialized adaptation for improved downstream tasks. By leveraging real-world corpora, we first provided...
