Abstract

People are frequently exposed to bacteria in the urban environment. Kitchen sinks within the urban environment harbour a wide variety of bacteria, potentially leading to increased risks of food contamination. Studies on the microbial community in domestic and institutional kitchen sinks, including characterization of antimicrobial resistance and biofilms, is often limited by low sample numbers or sequencing depth upon metagenomics analysis. Given the increasing population density in Flanders and the need to provide safe food, extensive characterisation of the sink microbiome is necessary. In this FWO SB-Beurs titled POEMBAKterie, I will use a Citizen Science approach to investigate the kitchen sink (or in Antwerp dialect "Poembak") microbiome on a large scale in Antwerp. Participants from households and various institutions (e.g. schools, retirement homes) will respond to a survey, swab their own kitchen sink and return the samples to our lab. I will use a combination of state-of-the-art metagenomic approaches and wet-lab microbiological analyses to investigate the taxonomy, presence of pathogens, antimicrobial resistance and biofilm formation in the presence of detergents and on different materials. Results will shed light on the bacteria living in sinks within the urban environment, and the implications for food safety, cleaning practices and sink design.

Abstract

This project is funded by an International Francqui Professor Chair grant, awarded to Prof. Dr. Peter Schulz. The prestigious Chair promotes inter-university cooperation which allows to strengthen scientific cooperation with foreign countries and to expand the horizons of our university staff. Schulz is a world-leading expert in the field of health communication, the scholarly field that studies the causes, content, and consequences of communication related to health. His research spans the entire field of health-related media, focusing on a wide range of health-related topics, and using a variety of research methods, in a wide range of international settings. The chair wlll be taken up for the period 01/04-2026 until 01/07-2026, with the University of Antwerp as the host institution (under supervision of Prof. Dr. Gert-Jan de Bruijn) and KU Leuven as the co-host institution (under supervision of Prof. Dr. Kathleen Beullens and Professor Dr. Tim Smits). Peter Schulz will not only hold an Inaugural lecture entitled 'Health Communication m a European Context', but will also actively contribute to ongoing doctorate and post-doc research projects. The chair will be concluded with a one-day mini-symposium 'Health Communication Dynamics in Turbulent Times'.

Abstract

Early diagnosis of osteoarthritis (OA) is necessary due to its high incidence, health impact, and the aging population. In this project, we develop standardized and high throughput screening strategies to characterize proteins and microRNAs released from joint cells under pathological conditions. Using artificial intelligence techniques, where complex molecular profiles are linked to both early and late clinical progression data, non-invasive predictive biomarkers for early OA diagnosis are established. Based on this, we develop a tool for very early OA detection. In parallel, we investigate how society and healthcare can become receptive to this screening tool.

Abstract

From noise-sensitive areas to oases of silence: with the large-scale citizen science project De Oorzaak, De Morgen (DM), the University Hospital Antwerp (UZA) and UAntwerpen are focusing on noise and noise perception in an urban environment. In 2024-2025, we will investigate how residents of different neighborhoods in Antwerp, Ghent and Leuven appreciate the environmental noise present. By means of questionnaires (subjective), smart sound sensors (objective) and medical research (UAntwerpen and UZA) we will classify which sounds are heard, what sound level these sounds have, how these sounds are experienced and what impact they have on health, stress, sleep and quality of life.

Abstract

Scientific breakthroughs, debates, and controversies reach the general public not through scientific publications, but largely through the news media. However, which breakthroughs, debates, and controversies are 'newsworthy' are by no means the same for everyone. In this project we investigate which (f)actors are important in the production of scientific news through qualitative and quantitative content analysis, and interviews with stakeholders.

Abstract

The DARTBAC project will prepare the Netherlands for the time when antibiotics are much less effective in the prevention and eradication of infection due to AntiMicrobial Resistance (AMR). DARTBAC will, from a material perspective, develop new antimicrobial technologies that are not based on antibiotics to target infection prevention and eradication on implant surfaces, in hard tissues and in soft tissues. In this way, we are unique yet synergistic with most other initiatives that focus on an antibiotics approach. In addition, we will maintain awareness of the emerging AMR problem in the Netherlands by informing the general public and HealthCare Practitioners (HCPs). DARTBAC is an interdisciplinary, 23 partner consortium consisting of (1) academic partners with expertise on infection, materials, imaging, in vitro models and social sciences; (2) technical university partners with expertise on material science, imaging, and in vitro and in vivo test models; (3) university medical centres with expertise on infection, microbiology, in vitro and in vivo models, imaging, animal models, material technology, and clinical studies; (4) small and large medical device companies and start-up companies with antimicrobial technologies; (5) scientific societies and knowledge institute of medical specialists with direct access to our target audience and patient groups for communication and dissemination; the Dutch National Institute for Public Health and the Environment (RIVM) with expertise on materials science and Adverse Outcome Pathways (AOPs); and (7) an international knowledge platform on AMR with expertise on AMR communication. Collectively, we are bridging the entire knowledge-chain regarding development of new material technologies to combat AMR.
