Effects of Exercise during Chemo- or Radiotherapy on Immune Markers

Introduction: Patients with cancer receiving radio- or chemotherapy undergo many immunological stressors. Chronic regular exercise has been shown to positively influence the immune system in several populations, while exercise overload may have negative effects. Exercise is currently recommended for all patients with cancer. However, knowledge regarding the effects of exercise on immune markers in patients undergoing chemo- or radiotherapy is limited. The aim of this study is to systematically review the effects of moderate- and high-intensity exercise interventions in patients with cancer during chemotherapy or radiotherapy on immune markers. Methods: For this review, a search was performed in PubMed and EMBASE, until March 2023. Methodological quality was assessed with the PEDro tool and best-evidence syntheses were performed both per immune marker and for the inflammatory profile. Results: Methodological quality of the 15 included articles was rated fair to good. The majority of markers were unaltered, but observed effects included a suppressive effect of exercise during radiotherapy on some proinflammatory markers, a preserving effect of exercise during chemotherapy on NK cell degranulation and cytotoxicity, a protective effect on the decrease in thrombocytes during chemotherapy, and a positive effect of exercise during chemotherapy on IgA. Conclusion: Although exercise only influenced a few markers, the results are promising. Exercise did not negatively influence immune markers, and some were positively affected since suppressed inflammation might have positive clinical implications. For future research, consensus is needed regarding a set of markers that are most responsive to exercise. Next, differential effects of training types and intensities on these markers should be further investigated, as well as their clinical implications.

Preliminary thoughts

Ascertaining the contribution of research is complex; this is not a conclusion but a starting point for the preliminary thoughts in this inaugural lecture. The guiding question is: where does this complexity lie? The dominant answer that has taken root in many practices flattens this complexity into a line. As a handle, or a rule of thumb. The concept of continuous effects serves as a crowbar to break open this one-dimensionality, not least to do more justice to practice-based research at universities of applied sciences. This allows for a different way of looking at how practice-based research contributes to change: from continuous effects ‘stretching each moment to the fullest’ and indicators of the effects of direct interactions, to multiple action perspectives beyond merely generating new knowledge to bring about change.

Late effects of cancer (treatment) and work ability: guidance by managers and professionals

BackgroundThe prevalence of the group of workers that had a cancer diagnosis in the past is growing. These workers may still be confronted with late effects of cancer (treatment) possibly affecting their work ability. As little is known about the guidance of this group, the aim of this study was to explore the experiences and ideas of managers and professionals about the guidance of these workers in the case of late effects of cancer (treatment). Given the positive associations with work ability of the job resources autonomy, social support by colleagues and an open organisational culture found in several quantitative studies, these job resources were also discussed. Further ideas about the influences of other factors and points of attention in the guidance of this group of workers were explored.MethodsSemi-structured interviews were conducted with managers (n = 11) and professionals (n = 47). Data-collection was from November 2019 to June 2020. The data were coded and analysed using directed content analyses.ResultsThe late effects of cancer or cancer treatment discussed were physical problems, fatigue, cognitive problems, anxiety for cancer recurrence, and a different view of life. The self-employed have less options for guidance but may struggle with late effects affecting work ability in the same way as the salaried. Late effects may affect work ability and various approaches have been described. Autonomy, social support of colleagues and an open organisational culture were regarded as beneficial. It was indicated that interventions need to be tailor-made and created in dialogue with the worker.ConclusionsEspecially with respect to cognitive problems and fatigue, guidance sometimes turned out to be complicated. In general, the importance of psychological safety to be open about late effects that affect work ability was emphasized. Moreover, it is important to take the perspective of the worker as the starting point and explore the possibilities together with the worker. Autonomy is an important factor in general, and a factor that must always be monitored when adjustments in work are considered. There is a lot of experience, but there are still gaps in knowledge and opportunities for more knowledge sharing.

3Mg - Magnesium (R)-3-hydroxybutyrate (Mg3HB)

Our unilateral diet has resulted in a deficiency of specific elements/components needed for well-functioning of the human body. Especially the element magnesium is low in our processed food and results in neuronal and muscular malfunctioning, problems in bone heath/strength, and increased chances of diabetes, depression and cardiovascular diseases. Furthermore, it has also been recognized that magnesium plays an important role in cognitive functioning (impairment and enhancement), especially for people suffering from neurodegenerative diseases (Parkinson disease, Alzheimer, etc). Recently, it has been reported that magnesium addition positively effects sleep and calmness (anti-stress). In order to increase the bioavailability of magnesium cations, organic acids such as citrate, glycerophosphate and glycinate are often used as counterions. However, the magnesium supplements that are currently on the market still suffer from low bio-availability and often do not enter the brain significantly.The preparation of dual/multiple ligands of magnesium in which the organic acid not only functions as a carrier but also has synergistically/complementary biological effects is widely unexplored and needs further development. As a result, there is a strong need for dual/multiple magnesium supplements that are non-toxic, stable, prepared via an economically and ecologically attractive route, resulting in high bioavailability of magnesium in vivo, preferably positively influencing cognition/concentration

ALGOL: Biocascading phytosterols from marine micro and macro algae, a feasibility study for biocircular economy

Micro and macro algae are a rich source of lipids, proteins and carbohydrates, but also of secondary metabolites like phytosterols. Phytosterols have important health effects such as prevention of cardiovascular diseases. Global phytosterol market size was estimated at USD 709.7 million in 2019 and is expected to grow with a CAGR of 8.7% until 2027. Growing adoption of healthy lifestyle has bolstered demand for nutraceutical products. This is expected to be a major factor driving demand for phytosterols. Residues from algae are found in algae farming and processing, are found as beachings and are pruning residues from underwater Giant Kelp forests. Large amounts of brown seaweed beaches in the province of Zeeland and are discarded as waste. Pruning residues from Giant Kelp Forests harvests for the Namibian coast provide large amounts of biomass. ALGOL project considers all these biomass residues as raw material for added value creation. The ALGOL feasibility project will develop and evaluate green technologies for phytosterol extraction from algae biomass in a biocascading approach. Fucosterol is chosen because of its high added value, whereas lipids, protein and carbohydrates are lower in value and will hence be evaluated in follow-up projects. ALGOL will develop subcritical water, supercritical CO2 with modifiers and ethanol extraction technologies and compare these with conventional petroleum-based extractions and asses its technical, economic and environmental feasibility. Prototype nutraceutical/cosmeceutical products will be developed to demonstrate possible applications with fucosterol. A network of Dutch and African partners will supply micro and macro algae biomass, evaluate developed technologies and will prototype products with it, which are relevant to their own business interests. ALGOL project will create added value by taking a biocascading approach where first high-interest components are processed into high added value products as nutraceutical or cosmeceutical.

An exploratory case study: In search of key enabling factors for effective participatory design for socio-technical innovation

The pace of technology advancements continues to accelerate, and impacts the nature of systems solutions along with significant effects on involved stakeholders and society. Design and engineering practices with tools and perspectives, need therefore to evolve in accordance to the developments that complex, sociotechnical innovation challenges pose. There is a need for engineers and designers that can utilize fitting methods and tools to fulfill the role of a changemaker. Recognized successful practices include interdisciplinary methods that allow for effective and better contextualized participatory design approaches. However, preliminary research identified challenges in understanding what makes a specific method effective and successfully contextualized in practice, and what key competences are needed for involved designers and engineers to understand and adopt these interdisciplinary methods. In this proposal, case study research is proposed with practitioners to gain insight into what are the key enabling factors for effective interdisciplinary participatory design methods and tools in the specific context of sociotechnical innovation. The involved companies are operating at the intersection between design, technology and societal impact, employing experts who can be considered changemakers, since they are in the lead of creative processes that bring together diverse groups of stakeholders in the process of sociotechnical innovation. A methodology will be developed to capture best practices and understand what makes the deployed methods effective. This methodology and a set of design guidelines for effective interdisciplinary participatory design will be delivered. In turn this will serve as a starting point for a larger design science research project, in which an educational toolkit for effective participatory design for socio-technical innovation will be designed.

Anthocyanins from agricultural waste: a source of next generation antimicrobials?

To treat microbial infections, antibiotics are life-saving but the increasing antimicrobial resistance is a World-wide problem. Therefore, there is a great need for novel antimicrobial substances. Fruit and flower anthocyanins have been recognized as promising alternatives to traditional antibiotics. How-ever, for future application as innovative alternative antibiotics, the full potential of anthocyanins should be further investigated. The antimicrobial potential of anthocyanin mixtures against different bacterial species has been demonstrated in literature. Preliminary experiments performed by our laboratories, using grape, rose and red cabbage anthocyanins against S. aureus and E. coli confirmed the antimicrobial potential of these substances. Hundreds of different anthocyanin entities have been described. However, which of these entities hold antimicrobial effects is currently unknown. Our preliminary data show that an-thocyanins extracted from grape, rose and red cabbage contain different collections of anthocyanin entities with differential antimicrobial efficacies. Our focus is on the extraction and characterization of anthocyanins from various crop residues. Grape peels are residues in the production of wine, while red rose and tulip leaves are residues in the production of tulip bulbs and regular horticulture. The presence of high-grade substances for pharmacological purposes in these crops may provide an innovative strategy to add value to other-wise invaluable crop residues. This project will be performed by the collaborative effort of our institute together with the Medi-cal Microbiology department of the University Medical Center Groningen (UMCG), 'Wijnstaete', a small-scale wine-producer (Lemelerveld) and Imenz Bioengineering (Groningen), a company that develops processes to improve the production of biobased chemicals from waste products. Within this project, we will focus on the antimicrobial efficacy of anthocyanin-mixtures from sources that are abundantly and locally available as a residual waste product. The project is part of a larger re-search effect to further characterize, modify and study the antimicrobial effects of specific anthocy-anin entities.

COMPLETE: Collaboration with parents in speech and language therapy

Zelfregie, empowerment, patiënt centraal: in elk rapport over de zorg komen we deze woorden tegen. Maar hoe doe je dat eigenlijk als zorgprofessional? Het project COMPLETE richt zich op de samenwerking tussen ouders van jonge kinderen met ontwikkelingsstoornissen en zorgprofessionals. Deze samenwerking is een van de belangrijkste aspecten van interventie bij jonge kinderen. Logopedisten werken dagelijks met peuters met taalontwikkelingsstoornissen. Taaltherapie is kindgericht, waarbij de samenwerking met ouders vaak slechts beperkt is vormgegeven. Logopedisten geven aan handelingsverlegenheid te ervaren in de samenwerking met ouders. Zij weten niet hoe ze echte betrokkenheid en partnerschap tot stand kunnen brengen. Ouders herkennen de ervaringen van professionals. Zij ervaren variatie in de mate waarin zij betrokken worden bij therapie en willen versterkt worden in de mogelijkheden om de ontwikkeling van hun kind te stimuleren. Het belang van samenwerking volgt ook uit effectstudies. Voor succesvolle interventies moeten ouders een belangrijke rol spelen in de behandeling, empowered worden en eigen regie ervaren. De urgentie van deze vraag komt specifiek aan de orde in de kennisagenda Logopedie en ouderbetrokkenheid is onderdeel van het kwaliteitsbeleid van de beroepsvereniging. Het project COMPLETE wil bijdragen aan de vragen van logopedisten en ouders. Het project start met kwalitatief onderzoek naar de behoeften en ervaren barrières in samenwerking bij logopedist en ouders en een systematisch literatuuronderzoek naar deze aspecten. Deze aspecten worden omgezet naar actieve doelstellingen waarmee professionals de samenwerking kunnen verbeteren. In de volgende stappen ontwikkelen we in co-design tools die hierbij ondersteunen. Daarnaast gaan we op zoek naar bestaande tools die we samen met de praktijk op bruikbaarheid testen en aanpassen. Het project resulteert in een toolbox voor samenwerking tussen logopedisten en ouders van jonge kinderen. De uitkomsten en opbrengsten van dit project zijn ook relevant voor andere zorgprofessionals die werken met ouders van jonge kinderen met ontwikkelingsstoornissen.

Cyberweerbaarheid. Een gemeentelijk offensief ter preventie van slachtofferschap van cybercrime.

Ambtenaren openbare orde en veiligheid spelen een centrale rol in de zorg voor maatschappelijke veiligheid. Hun focus ligt van oudsher op de preventie van slachtofferschap van veelvoorkomende criminaliteit (zoals diefstal, vernielingen en vandalisme) en high impact crime (zoals woninginbraak, overvallen en straatroven) binnen hun verzorgingsgebied. Intussen heeft de digitalisering van de samenleving een ongeëvenaarde gelegenheid voor criminaliteit gecreëerd. De totale maatschappelijke schade van cybercrime werd voor 2018 op 10 miljard euro geschat (1% van BNP). Uit cijfers van het CBS blijkt dat tussen 2012 en 2018 het slachtofferschap van hacken zelfs hoger lag dan dat van fietsendiefstal. Nederlandse gemeenten hebben cybercrime in de afgelopen twee jaar dan ook breed als beleidsprioriteit omarmd. Maar in de vertaling van deze beleidsprioriteit naar concrete acties gaat het mis. Duidelijk is dat de ambtenaren openbare orde en veiligheid een taak voor zichzelf zien in de preventie van cybercrime, maar waar te beginnen? In dit project bundelen professionals uit twaalf gemeenten en vier regionale veiligheidsnetwerken hun slagkracht met onderzoekers van twee hogescholen en het NSCR voor de cyberweerbaarheid van de samenleving. De hoofdvraag van dit project luidt: Met welke interventies kunnen ambtenaren openbare orde en veiligheid de cyberweerbaarheid van burgers en bedrijven binnen hun gemeente vergroten? Middels actieonderzoek werken professionals van gemeenten en regio’s samen met onderzoekers aan het verbeteren van bestaande en het ontwikkelen van nieuwe interventies. Daarbij verscherpen zij hun beeld van de omvang en achtergronden van slachtofferschap van cybercrime. Ook onderzoeken zij achtergronden en verklaringen voor het risicobewustzijn en preventief gedrag onder doelgroepen. Deze inzichten worden in verschillende iteraties aangevuld met effectstudies, om tot een set beproefde interventies te komen waarmee de cyberweerbaarheid van burgers en bedrijven zal toenemen.
