Recent Developments in Islet Biology: A Review With Patient Perspectives.

Navigating the coronavirus disease-2019 (COVID-19, now COVID) pandemic has required resilience and creativity worldwide. Despite early challenges to productivity, more than 2,000 peer-reviewed articles on islet biology were published in 2021. Herein, we highlight noteworthy advances in islet research between January 2021 and April 2022, focussing on 5 areas. First, we discuss new insights into the role of glucokinase, mitogen-activated protein kinase-kinase/extracellular signal-regulated kinase and mitochondrial function on insulin secretion from the pancreatic ß cell, provided by new genetically modified mouse models and live imaging. We then discuss a new connection between lipid handling and improved insulin secretion in the context of glucotoxicity, focussing on fatty acid-binding protein 4 and fetuin-A. Advances in high-throughput "omic" analysis evolved to where one can generate more finely tuned genetic and molecular profiles within broad classifications of type 1 diabetes and type 2 diabetes. Next, we highlight breakthroughs in diabetes treatment using stem cell-derived ß cells and innovative strategies to improve islet survival posttransplantation. Last, we update our understanding of the impact of severe acute respiratory syndrome-coronavirus-2 infection on pancreatic islet function and discuss current evidence regarding proposed links between COVID and new-onset diabetes. We address these breakthroughs in 2 settings: one for a scientific audience and the other for the public, particularly those living with or affected by diabetes. Bridging biomedical research in diabetes to the community living with or affected by diabetes, our partners living with type 1 diabetes or type 2 diabetes also provide their perspectives on these latest advances in islet biology.

A WHO key informant language survey of people with lived experiences of diabetes: Media misconceptions, values-based messaging, stigma, framings and communications considerations.

AIMS: This study aimed to learn from people with lived experiences of diabetes to raise the quality of diabetes communications. METHODS: An online key informant survey for people (18+) with a direct and/or adjacent (caregiver, friend, family-member etc.,) lived experience of diabetes. Through thematic analysis, we gathered insights on perceptions of media reporting on diabetes and communicating with accuracy, impact and without stigma. Descriptive analysis also investigated effective values for WHO to communicate diabetes with key audiences of policy-makers, funding partners and the general public. RESULTS: 918 respondents in 58 WHO Member States were analysed. Participants identified five key themes requiring more appropriate consideration in the media: accurately defining diabetes types, over-emphasis on sugar and lifestyle, negative impacts of diabetes stigma, burden of costs (financial, personal and interpersonal) and mental health. Irrespective of audience, key values-based messages identified as important for WHO to convey included: 'urgency', 'preventing suffering', 'improving wellbeing' and 'meaningful engagement' of people with lived experience. CONCLUSION: Learning from people with lived experience of diabetes identifies key diabetes communication considerations. Continued meaningful engagement of this group, including in WHO's work and the multistakeholder diffusion of this methodology to local contexts, could improve public discourse on diabetes and related policies.

Discoveries from the study of longstanding type 1 diabetes.

Award programmes that acknowledge the remarkable accomplishments of long-term survivors with type 1 diabetes have naturally evolved into research programmes to determine the factors associated with survivorship and resistance to chronic complications. In this review, we present an overview of the methodological sources of selection bias inherent in survivorship research (selection of those with early-onset diabetes, incidence-prevalence bias and bias from losses to follow-up in cohort studies) and the breadth and depth of literature focusing on this special study population. We focus on the learnings from the study of longstanding type 1 diabetes on discoveries about the natural history of insulin production loss and microvascular complications, and mechanisms associated with them that may in future offer therapeutic targets. We detail descriptive findings about the prevalence of preserved insulin production and resistance to complications, and the putative mechanisms associated with such resistance. To date, findings imply that the following mechanisms exist: strategies to maintain or recover beta cells and their function; activation of specific glycolytic enzymes such as pyruvate kinase M2; modification of AGE production and processing; novel mechanisms for modification of renin-angiotensin-aldosterone system activation, in particular those that may normalise afferent rather than efferent renal arteriolar resistance; and activation and modification of processes such as retinol binding and DNA damage checkpoint proteins. Among the many clinical and public health insights, research into this special study population has identified putative mechanisms that may in future serve as therapeutic targets, knowledge that likely could not have been gained without studying long-term survivors.
