New NIH Genomics Data Management Policy

New NIH Genomics Data Management Policy

Announcements, News
The National Institutes of Health (NIH) has issued updated data management policies, which introduce new security standards in the Genomic Data Sharing (GDS) Policy. Specifically, “NIH Security Best Practices for Users of Controlled-Access Data” require that data managed on institutional IT systems and third-party computing infrastructures that meet certain standards in accordance with NIST SP 800-171 “Protecting Controlled Unclassified Information in Nonfederal Information Systems and Organizations.” These new policies will be effective on January 25, 2025, at which point adherence to this standard will be included in new or renewed Data Use Certifications or similar agreements stipulating terms of access to controlled-access human genomic data regardless of whether the Approved User is supported by NIH or not.

It will discuss the two primary copyright law issues: whether the training of large language models (LLMs) and the outputs of gen AI systems constitute copyright infringement, and whether work created with the assistance of gen AI systems should be copyrightable and owned by the human end-user. It will also raise legal issues raised by deepfakes under right of publicity (name, image, likeness) law, privacy, trademark, and various criminal laws. Finally, the talk will discuss ethical considerations in law and general…

However, there are many significant challenges to apply and develop AI for medical applications. Deep-learning based systems are at the forefront of AI but they are notorious at demanding large amounts of carefully labeled and annotated data. While simple labeling tasks can rely on crowdsourcing, medical data labeling requires expertise that could be rare and costly. In addition, there are usually significant bias and class imbalance issues with medical data. Expanding the knowledge base and diversity of…

The development of the RGAN package (Neunhoeffer, 2022) now allows for a user-friendly command line interface for training GANs on tabular or image data in the R environment. This tutorial guides attendees through the process of training and evaluating a GAN trained using the RGAN framework through a real clinical example dataset. Attendees who wish to follow along must have the following software installed: The R…

Goodfellow’s 2014 introduction of generative adversarial networks (GANs) was a watershed moment for the generative modeling domain and has since been widely used in a wide variety of contexts. This presentation and accompanying tutorial introduce participants to a lesser-used application of GANs: Their ability to generate synthetic patient records with data largely mirroring the same data obtained from real patients. This presentation illustrates an example using data from patients admitted to UK hospitals for either Acute Coronary Syndrome (ACS) or Takotsubo Syndrome (TTS),…

Recurrent neural networks (RNNs) and Transformer are neural network architectures designed to efficiently model temporal connections within a sequence and handling variable sequence lengths in a dataset. However, RNNs suffer from the so-called vanishing or exploding gradient problems, which also reduces its ability to pass information in a long sequence. Transformer solves this problem through a self-attention mechanism but faces challenges in efficiently scaling to long sequences because the self-attention computation is quadratic with respect to the sequence length. We will present several orthogonal RNN models that we have developed to address the vanishing/exploding…

If successful, state governments could use forecasts to properly prepare and distribute resources effectively. The approach taken primarily uses county and district level aggregations of EMS opioid overdose encounters and forecasts future counts at a monthly level. A variety of additional covariates were also tested to determine their impact on the model’s performance. Models with different levels of complexity were evaluated as well to optimize training time and accuracy. The results…
