Abstract

Ever since the publication of ChatGPT, natural language processing (NLP) and large language models (LLM) are popular topics everybody has at least heard about.
Interestingly, there was not much development and interest in the German clinical community until this recent development (same as digitalisation in general). Now, everybody wants to be the first in utilising this (more or less) new technique. However, most of the datasets and models available are focused on English and the adaption to German or other languages and dialects is not a trivial task.
This talk will give an overview about the challenges and possible solutions in German clinical language processing, as well as the potentials and risks of recent developments in NLP research.

Abstract

The detrimental effects of mental stress on human health have been known for decades, and it has now developed into a major concern in our modern society, where it is regarded as a rising problem and an inevitable part of our everyday life. Psychological stress was shown to be separated into two types: acute and chronic. If stress is not recognized early, it can lead to a variety of diseases and major health problems, including hypertension and coronary disease, irritable bowel syndrome, gastroesophageal reflux disease, generalized anxiety disorder, and depression. In this talk, we will mention some experiments for recognizing stress by using unobtrusive wearables in different environments such as laboratory, real-life events and in the wild. Privacy preserving stress recognition approaches will be also explained. We will also talk about methods for alleviating stress and their performances for decreasing stress levels.

Abstract

A common theme of many science-fiction scenarios is that the physician of the future seems to be able to wirelessly scan a person and determine his or her health status without physical interference. A common theme of today’s diagnostics is the use of invasive procedures, stationary devices, wires, adhesive-based connections, and the associated limitations in flexibility and comfort. At the same time, the development of sensing modalities for unobtrusive sensing is ever increasing, both in the scientific community as well as in the industry. In part, this ever-accelerating development is fueled by the developments in artificial intelligence. In this talk, we will explore how artificial intelligence, in particular machine learning, sensor fusion, and computer vision may be used to extract diagnostic information using cameras and other types of unobtrusive sensors.

Abstract

Efforts made to make data findable, accessible, interoperable and reusable (FAIR) have shown to lead to a more sophisticated data stewardship in various scientific disciplines. One positive consequence of a so-called FAIRification process is the increase in data use and reuse, another observed benefit is the reduction of irreproducle scientific results due to more transparency and richer documentation.

In this talk, I will introduce the FAIR principles in detail using examples from our own work at the 新万博体育下载_万博体育app【投注官网】ical Informatics Lab. We conducted a baseline assessment of the NFDI4Health metadata schema and worked to FAIRify the core data set used for diabetes research in Germany, the SHIP laboratory data set, and biosimulation models. Currently we run a FAIR assessment of the 新万博体育下载_万博体育app【投注官网】ical Informatics Core Data Set, funded by EOSC. I will highlight the usefulness of making own data FAIR and present a few tools to do so. I will also discuss with you why it is not easy to achieve FAIRness, and we will learn about possible next steps to implement the FAIR principles in the German medical research community at large.

For example, we recommend that key performance indicators be established to adequately evaluate how data FAIRness benefits health research. Future work also involves developing guidelines for researchers in the form of a simple checklist they can follow. You can read more about these topics in our recent scoping review on FAIR data in health care research (https://www.jmir.org/2023/1/e45013).

Abstract

Deep convolutional neural networks (DCNNs) can be trained to recognize and classify rare genetic disorders based on their characteristic facial features.?GestaltMatcher?is such an AI that learned to construct a clinical face phenotype space (CFPS) in which portrait images can be placed. Distances in between medical images in the CFPS can be used to quantify syndromic similarities. Cluster analysis in that space reveals close proximity of molecular pathway diseases and can, therefore, be used to support "lumping decisions". Furthermore, the pleiotropic genes causing multiple disorders can also result in distinct facial?gestalt. Thus, cluster analysis can also provide evidence for "splitting decisions", that is indication for different pathomechanisms based on?gestalt?analysis.?

Abstract

Clinical decision support tools with artificial intelligence (AI) technologies could synthesize the abundance of data collected in hospitals to help clinicians in identifying which patients may need specific attention and steer additional mental health resources to those at high risk. However, methodological and implementation challenges, such as algorithmic fairness and generalizability, deserve further attention when developing AI-tools within the (mental) healthcare domain. In this talk, we will address the potential and pitfalls for developing responsible AI for mental healthcare.

Abstract

?Epigenetic mechanisms play a crucial role in establishing and preserving cellular states and function throughout an organism’s life. DNA methylation is an essential part of this multilayered regulation and displays a highly conserved, characteristic bimodal distribution across most somatic cell types. For yet unknown reasons, the distribution of DNA methylation is fundamentally different tumors, an intermediate gain of DNA methylation at certain CpG islands and a partial loss of methylation across gene-poor regions. These two features make DNA methylation an ideal readout for tumor-type prediction from sequencing data.

Specifically in the field of neuropathology, DNA methylation-based tumor type classification has recently become part of the WHO. However, even though the field aimed to achieve an intraoperative differential diagnosis for decades, accomplishing this within a clinically relevant timeframe has remained elusive.

Recent advances in third-generation sequencing technologies have brought this goal within reach. To allow for intraoperative CNS tumor type classification within less than one hour, we developed MethyLYZR, a Na?ve Bayesian framework enabling live classification of cancer epigenomes using fully tractable single-CpG resolution modeling while avoiding the need for feature selection or ad hoc?model training. MethyLYZR can be run in parallel to an ongoing Nanopore experiment with negligible computational cost and provides clinically relevant and accurate cancer classification results within 15 minutes of sequencing (94% accuracy).?

Abstract

Electrical sensors are used for many neurological or cardiological examinations. Here this is referred to as electroencephalography (EEG) or electrocardiography (ECG). For this purpose, electrodes are placed over the chest or on the head and electrical voltages are measured. This works quite well, but the propagation from the sources (the heart or the brain) to the sensors usually follows very "unusual" (material-dependent) paths. Alternatively, newly developed magnetic sensors can be used - here propagation takes place in a way that is noticeably more "material-independent" for most people. Due to the magnetic measurements, it might be possible in the future to perform much more accurate medical analyses, even without body contact - similar to the "tricorder" from "Star Trek".

In this talk, the Collaborative Research Center 1261 (Magnetoelectric Sensors: From Composite Materials to Biomagnetic Diagnostics), which deals with the research of novel magnetoelectric sensor systems, will be presented first. Then, some of the sensor principles designed to measure low-frequency, extremely weak magnetic fields in typical environments, i.e., without magnetic shielding and without expensive cooling systems, are presented. A brief outlook on biomedical applications for these types of sensors concludes the talk.
