A research team at Inselspital, Bern University Hospital, University of Bern and Caresyntax has succeeded in proving that artificial intelligence can reliably assess surgeons’ skills. A method involving a three-stage procedure has been presented that correctly designates good and mediocre performance with a high accuracy rate. This paves the way for further steps towards AI-supported expert systems.

Efficient treatment of stroke with AI and federated learning (09.03.2021)

A research team of Inselspital, University Hospital Bern, the University of Bern and the «Centre hospitalier universitaire vaudois» (CHUV) uses AI to improve efficiency of treatment after stroke. The project Advanced Stroke Analysis Platform (ASAP) applies federated learning that links the database of each hospital center without exchange of raw data. Innosuisse, the Swiss innovation agency, promotes the project.

Reliably predicting progression of Covid-19 (03.03.2021)

Inselspital, Bern University Hospital and the University of Bern are currently launching the world’s first multicenter, international study on AI-assisted prediction of severe progressions of Covid-19. The research uses artificial intelligence to evaluate extensive clinical, image-morphological and laboratory data. The study, which is funded by the Swiss National Science Foundation, aims to provide reliable predictions as to whether a specific case would lead to a severe progression of Covid-19.

Multi-omics approach (JPG, 149KB): Complex data, consisting of CT, X-ray data, clinical and laboratory data, serve the AI algorithm as a basis for the prognosis of the acute (7-day) and chronic course. (Alexander Poellinger, Inselspital).

Deep learning reads tissue microarrays of colorectal cancer (10.02.2021)

Tissue microarray (TMA) core images are a treasure trove for AI applications. But a common problem with TMAs is multiple sectioning of the TMA block, which can change the content of the core and requires re-labelling of each spot image. The Institute of Pathology of the University of Bern has investigated different ensemble methods for colorectal tissue classification using high-throughput TMAs. Their high-accuracy algorithm for colorectal tissue classification into “tumor“, “normal“ or “other” tissue showed very good predictive accuracy and is amenable to images from different institutions, core sizes and stain intensity.

A NEAT reduction of complex neuronal models accelerates brain research (27.01.2021)

Unlike their simple counterparts in AI applications, neurons in the brain use dendrites – intricate tree-like branches – to find relevant chunks of information. Now, neuroscientists from the University of Bern have discovered a new computational method to make complex dendrite models much simpler. This could enable AI applications to process information much like the brain does.

AI for quality assurance in radiation therapy planning: Project funded (18.01.2021)

The Medical Image Analysis group at the ARTORG Center, University of Bern, received funding support from the Swiss Cancer League to work on AI technologies for quality assurance in Radiation Therapy planning, in partnership with the Radiation Oncology Departments of the USZ and the Inselspital.

PI Mauricio Reyes comments: “We are thankful for this support as it has the potential to create a new generation of technologies dedicated to improve quality assurance aspects in radiation therapy planning.” The project ranked third out of seventy seven submitted projects.

Thomas Sauter, Head of Education, eHealth and Emergency Telemedicine at Bern University Hospital's emergency center has been appointed by the University Executive Board for an endowed professorship in emergency telemedicine. The assistant professorship was established thanks to the support of the Touring Club Switzerland (TCS). It deals with "eHealth" in the field of emergency medicine and is one of the very few of its kind in the world.

Sinergia project on trans-omics against colorectal cancer to start (06.01.2021)

The University of Bern Institute of Pathology has won a Swiss Science Foundation Sinergia grant to develop an integrative computational and clinical perspective on colorectal cancer, an important cause of cancer-related mortality in Switzerland. In collaboration with the ZHAW, the Institute of System Biology, ETH Zürich and IBM Research, the group will improve patient stratification, prognosis and treatment prediction via an AI-driven multi-modal classifier trained to predict molecular classification and identify other important clinical variables.

Smartphone verifies compliance with Mediterranean diet (29.12.2020)

The ARTORG Artificial Intelligence in Health and Nutrition lab, the Epidemiology, Biostatistics and Prevention Institute of the University of Zurich and Oviva SA have together developed a smartphone application to automatically estimate whether a person adheres to a health-promoting Mediterranean diet. First results of the novel system are promising.

AI X-ray analysis detects Covid-19 more reliably (11.12.2020)

A team of researchers at Inselspital, Bern University Hospital, and the ARTORG Center for Biomedical Research, University of Bern, has developed a new chest radiography image analysis for the detection of COVID-19. The algorithmic method was trained for various diagnoses on 8000 X-ray images. The researchers compared this artificial intelligence (AI) with standard, diagnostic annotation by radiologists. Especially for distinguishing Covid-19 from non-Covid-19 lung disease, AI provided significantly more reliable results.
