Abstract: Methods for treating coronavirus disease 2019 (COVID-19), the disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections, are described. The methods can be used to reduce the severity of outcomes related to COVID-19, such as hospitalization and ventilation. For example, the methods can involve treatment of a subject with a therapeutic agent that degrades hyaluronan and/or an agent that neutralizes a hyaluronan receptor, e.g., CD44, such as an anti-CD44 antibody.

Abstract: Techniques, systems, and devices are described for providing a computational frame for estimating high-dimensional stochastic behaviors. In one exemplary aspect, a method for performing numerical estimation includes receiving a set of measurements of a stochastic behavior. The set of correlated measurements follows a non-standard probability distribution and is non-linearly correlated. Also, a non-linear relationship exists between a set of system variables that describes the stochastic behavior and a corresponding set of measurements. The method includes determining, based on the set of measurements, a numerical model of the stochastic behavior. The numerical model comprises a feature space comprising non-correlated features corresponding to the stochastic behavior. The non-correlated features have a dimensionality of M and the set of measurements has a dimensionality of N, M being smaller than N.

Abstract: Described herein are systems and methods to enable generation of high-quality summaries of documents that have questions and answers. To help summarize such documents, parsing methods are disclosed that account for different document formats. Methods are disclosed to anonymize personal and identifying information present in the documents. An ontology is defined to categorize dialog acts for the questions and answers present. Classifiers are disclosed based on this ontology. Methods are also disclosed to transform a question-answer pair to a canonical form. Based on the dialog acts for the question and answer combination, transformation methods were developed that build upon each of traditional NLP, and deep learning, techniques.

Abstract: An insulin device configured to control insulin dispensing based on insulin sensitivity. The insulin device includes a processor configured to receive insulin dosing schedule information, psychological stress level data, and body mass index (BMI) data; a sensor configured to generate a blood glucose level measurement. The sensor is calibrated as a function of the psychological stress level data and the BMI data and the processor is configured to monitor and detect changes of the blood glucose level measurement that are determined to have occurred as a function of changes of the psychological stress level data, and identify a time when the BMI data counteracts a detected change in the blood glucose level measurement. The insulin device also includes an insulin dispensing valve controlled by the processor to change the insulin dosing schedule information in accordance with the counteracting BMI data.

Abstract: The gene responsible for encoding SERT has a functional polymorphism at the 5?-regulatory promoter region, which results in two forms, long (L) and short (S). The LL-genotype is hypothesized to play a key role in the early onset of alcohol use. The present invention discloses the differences in treatment and diagnosis based on the L or short genotypes as well as on a single nucleotide polymorphism of the SERT gene, the 3? UTR SNP rs1042173. The present invention demonstrates the efficacy of using the drug ondansetron and similar drugs for treatment based on variations in the polymorphisms of the SERT gene as well as methods for diagnosing susceptibility to abuse of alcohol and other addiction-related diseases and disorders.

Abstract: A medical system for ablating a tissue site with real-time monitoring during an electroporation treatment procedure. A pulse generator generates a pre-treatment (PT) test signal prior to the treatment procedure and intra-treatment (IT) test signals during the treatment procedure. A treatment control module determines impedance values from the PT test signal and IT test signals and determines a progress of electroporation and an end point of treatment in real-time based on the determined impedance values while the treatment progresses.
