WORLDSymposium 2023 Preliminary Program on Lysosomal Diseases

On Tuesday afternoon, the 2nd Annual Robert J. Gorlin Symposium honored the work of Robert James Gorlin, DDS, PhD. Dr. Gorlin was an maxillofacial pathologist, geneticist and academician at the University of Minnesota School of Dentistry. His groundbreaking research in genetic disorders of the head and neck, spanning over 50 years, revolutionized the understanding of the morphology of lysosomal diseases and many other genetic disorders. The 2nd Annual Robert J. Gorlin Symposium focused on precision medicine in lysosomal diseases.

Following the Gorlin Symposium, seasoned researchers provided a global review of the past years’ advances, including a state-of-the-art overview of lysosome biology, diseases and therapies in the Emerging Trends Session. This review evolves every year, providing a summary of the latest research trends, new knowledge, and other discoveries. The course is intended for researchers and health care practitioners who are interested in being current on recent advances in the basic science, diagnosis, and treatment of lysosomal diseases.

After the presentation of the Innovation Award, the formal scientific sessions of WORLDSymposium 2023 officially began with presentations on laboratory research for lysosomal disease. Presentations during the Basic Science sessions are designed to improve our understanding or prediction of the phenomena involved in lysosomal pathology at a molecular, cellular, and animal model level in order to forwardly think about diagnosis and treatment of lysosomal conditions. These Basic Science sessions are always innovative and present the latest findings in the field. Download the WORLDSymposium 2023 program (PDF 200KB).

The fourth research day of the meeting began with the New Treatment Award. Then, for the fourth year, the Contemporary Forum allowed for presentation of scientific abstracts — Basic, Translational, and Clinical — submitted by industry first-author researchers. Although the first three days of WORLDSymposium were accredited and approved for CME credit, Commercial Interests were not eligible for ACCME accreditation. The Contemporary Forum allowed commercial interests to present their work to the WORLDSymposium audience, in that non-CME session, while being held to all the same standards as the ACCME accredited sessions and scored for merit and interest by the same Program Committee.

Toward bringing the most recent research to the platform of WORLDSymposium 2023, after the late-breaking abstract submissions closed on December 1, 2022, selected late-breaking abstracts were identified by the Program Committee as being suitable for platform presentation. In order to provide access to the “hot-off-the-presses” content from these researchers, late-breaking abstracts were reviewed and scored, and the top-scoring abstracts were selected for presentation during the 2023 meeting.
