Background: In the Netherlands, general practitioners (GPs) play a key role in provider-initiated HIV testing, but opportunities for timely diagnosis are regularly missed. We implemented an educational intervention to improve HIV testing by GPs from 2015 to 2020, and observed a 7% increase in testing in an evaluation using laboratory data. The objective for the current study was to gain a deeper understanding of whether and how practices and perceptions of GPs’ HIV/sexually transmitted infection (STI) testing behaviour changed following the intervention. Methods: We performed a mixed-methods study using questionnaires and semi-structured interviews to assess self-reported changes in HIV/STI testing by participating GPs. Questionnaires were completed by participants at the end of the final educational sessions from 2017 through 2020, and participating GPs were interviewed from January through March 2020. Questionnaire data were analysed descriptively, and open question responses were categorised thematically. Interview data were analysed following thematic analysis methods. Results: In total, 101/103 participants completed questionnaires. Of 65 participants that were included in analyses on the self-reported effect of the programme, forty-seven (72%) reported it had changed their HIV/STI testing, including improved STI consultations, adherence to the STI consultation guideline, more proactive HIV testing, and more extragenital STI testing. Patients’ risk factors, patients’ requests and costs were most important in selecting STI tests ordered. Eight participants were interviewed and 15 themes on improved testing were identified, including improved HIV risk-assessment, more proactive testing for HIV/STI, more focus on HIV indicator conditions and extragenital STI testing, and tools to address HIV during consultations. However, several persistent barriers for optimal HIV/STI testing by GPs were identified, including HIV-related stigma and low perceived risk. Conclusions: Most GPs reported improved HIV/STI knowledge, attitude and testing, but there was a discrepancy between reported changes in HIV testing and observed increases using laboratory data. Our findings highlight challenges in implementation of effective interventions, and in their evaluation. Lessons learned from this intervention may inform follow-up initiatives to keep GPs actively engaged in HIV testing and care, on our way to zero new HIV infections.
While the original definition of replacement focuses on the replacement of the use of animals in science, a more contemporary definition focuses on accelerating the development and use of predictive and robust models, based on the latest science and technologies, to address scientific questions without the use of animals. The transition to animal free innovation is on the political agenda in and outside the European Union. The Beyond Animal Testing Index (BATI) is a benchmarking instrument designed to provide insight into the activities and contributions of research institutes to the transition to animal free innovation. The BATI allows participating organizations to learn from each other and stimulates continuous improvement. The BATI was modelled after the Access to Medicine Index, which benchmarks pharmaceutical companies on their efforts to make medicines widely available in developing countries. A prototype of the BATI was field-tested with three Dutch academic medical centers and two universities in 2020-2021. The field test demonstrated the usability and effectiveness of the BATI as a benchmarking tool. Analyses were performed across five different domains. The participating institutes concluded that the BATI served as an internal as well as an external stimulus to share, learn, and improve institutional strategies towards the transition to animal free innovation. The BATI also identified gaps in the development and implementation of 3R technologies. Hence, the BATI might be a suitable instrument for monitoring the effectiveness of policies. BATI version 1.0 is ready to be used for benchmarking at a larger scale.
Aanleiding: De belangstelling voor gezonde en veilige voeding is groot. Bij de gezondheidseffecten van voeding spelen de darmen een cruciale rol. Verschillende soorten bedrijven hebben behoefte aan natuurgetrouwe testmodellen om de effecten van voeding op de darmen te bestuderen. Ze zijn vooral op zoek naar modellen waarvan de uitkomsten direct vertaalbaar zijn naar het doelorganisme (de mens of bijvoorbeeld het varken) en die niet gebruikmaken van kostbare en maatschappelijke beladen dierproeven. Doelstelling Het project 2-REAL-GUTS heeft als doel om twee innovatieve dierproefvrije darmmodellen geschikt te maken voor onderzoek naar voedingsconcepten en -ingrediënten. De twee darmmodellen die worden toegepast zijn darmorganoïden, minidarmorgaantjes bestaande uit stamcellen, en darmexplants bestaande uit hele stukjes darm verkregen uit relevante organismen. Beide modellen hebben potentieel heel uitgebreide toepassingsmogelijkheden en hebben ook grote voordelen ten opzichte van de huidige veelgebruikte cellijnen, omdat ze meerdere in de darm aanwezige celtypen bevatten en uit verschillende specifieke darmregio's te verkrijgen zijn. Gezamenlijk gaan de partners werken aan: 1) het aanpassen van de kweekomstandigheden zodat darmmodellen geschikt worden om de vragen van partners te beantwoorden; 2) het vaststellen van de toepassingsmogelijkheden van de darmmodellen door verschillende stoffen en producten te testen. Beoogde resultaten Kennisconferenties, publicaties en exploitatie van de modellen zullen zorgen voor het verspreiden van de opgedane kennis. Omdat het project gebruikmaakt van moderne, op de toekomst gerichte laboratoriumtechnieken (kweekmethoden met stamcellen en vitaal weefsel, moleculaire analyses en microscopie), leent het zich uitstekend om geïmplementeerd te worden in het hbo-onderwijs. Als spin-off zal het project dan ook voorzien in een specifieke, voor Nederland unieke hbo-minor op het gebied van stamcel- en aanverwante technologie (zoals organ-on-a-chiptechnologie).
Size measurement plays an essential role for micro-/nanoparticle characterization and property evaluation. Due to high costs, complex operation or resolution limit, conventional characterization techniques cannot satisfy the growing demand of routine size measurements in various industry sectors and research departments, e.g., pharmaceuticals, nanomaterials and food industry etc. Together with start-up SeeNano and other partners, we will develop a portable compact device to measure particle size based on particle-impact electrochemical sensing technology. The main task in this project is to extend the measurement range for particles with diameters ranging from 20 nm to 20 um and to validate this technology with realistic samples from various application areas. In this project a new electrode chip will be designed and fabricated. It will result in a workable prototype including new UMEs (ultra-micro electrode), showing that particle sizing can be achieved on a compact portable device with full measuring range. Following experimental testing with calibrated particles, a reliable calibration model will be built up for full range measurement. In a further step, samples from partners or potential customers will be tested on the device to evaluate the application feasibility. The results will be validated by high-resolution and mainstream sizing techniques such as scanning electron microscopy (SEM), dynamic light scattering (DLS) and Coulter counter.
Developing and testing several AR and VR concepts for SAMSUNG (Benelux) Samsung and Breda University of Applied Sciences decided to work together on developing and testing several new digital media concepts with a focus on VR and gaming. This collaboration has led to several innovative projects and concepts, among others: the organisation of the first Samsung VR jam in which game and media students developed new concepts for SAMSUNG GEAR in 24 hours, the pre-development of a VR therapy concept (Fear of Love) created by CaptainVR, the Samsung Industry Case in which students developed new concepts for SAMSUNG GEAR (wearables), the IGAD VR game pitch where over 15 VR game concepts were created for SAMSUNG VR GEAR and numerous projects in which VR concepts are developed and created using new SAMSUNG technologies. Currently we are co-developing new digital HRM solutions.
