Supporting early-career dementia researchers: Identifying support needs and ways forward via a European study

INTRODUCTION

Early-career researchers contribute significantly to dementia research and clinical practice. However, a growing group of early-career dementia researchers (ECDRs) lack appropriate support throughout their careers. Thus, we aim to (i) explore support needs, (ii) determine recommendations, and (iii) set the agenda for organizations to better support ECDRs.

METHODS

An iterative, explanatory sequential mixed-methods design was applied. First ECDRs' needs were identified using an online survey informed by the Vitae Researcher Development Framework. Next, priority areas were selected and explored qualitatively with ECDRs in two workshops, utilizing the World Café methodology.

RESULTS

Sixty-five ECDRs throughout Europe completed the survey, with the majority reporting that greater support is needed in terms of funding and career opportunities, social support and well-being, and "wide-reaching" dissemination.

DISCUSSION

Based on the findings, six recommendations for support organizations, funding bodies, and universities to better support ECDRs are formulated, each intended for specific target audiences.

HIGHLIGHTS

This article reports on focal points of career-related support needed in doctoral education and postdoctoral employment to foster a healthier academic environment, including finance, work-life balance, dissemination of research findings, and supervision, both in general and in dementia fields specifically. Funding and resources were identified as a significant challenge, and there was a call for more long-term positions and transition funding for postdoctoral researchers. Early-career dementia researchers addressed the need for support in producing outputs for non-academic audiences, including people living with dementia. The importance of disseminating research to diverse audiences has long been recognized; thus, it is critical that early-career dementia researchers be supported in this effort. Recommendations were formulated for researcher support (organizations), funding bodies, and universities. These recommendations include providing support for disseminating research to non-academic audiences, offering training in supervision skills, and promoting peer-to-peer mentoring and social activities for early-career dementia researchers.

Biodistribution and intestinal inflammatory response following voluntary oral intake of silver nanoparticles by C57BL/6J mice

Silver nanoparticles (AgNP) are among the most widely commercialized nanomaterials globally, with applications in medicine and the food industry. Consequently, the increased use of AgNP in the food industry has led to an unavoidable rise  in human exposure to these nanoparticles. Their widespread use raises concerns about potential hazards to human health, specifically their intestinal pro-inflammatory effects. Thus, the main objective of this study was to evaluate the biological effects of two subacute doses of 5 nm polyvinylpyrrolidone (PVP)-AgNP in C57BL/6J mice. One mg/kg body weight or 10 mg/kg bw was provided once a day for 14 days, using a new technology (HaPILLness) that allows voluntary, stress-free, and accurate oral dosing. It was observed that after oral ingestion, while AgNP is biodistributed throughout the entire organism, most of the ingested dose is excreted in the feces. The passage and accumulation of AgNP throughout the intestine instigated a prominent inflammatory response, marked by significant histological, vascular, and cellular transformations. This response was driven by the activation of the nuclear factor-кB (NF-кB) inflammatory pathway, ultimately leading to the generation of multiple cytokines and chemokines.
