Abstract
AIMS To analyze the main contributions to the discovery of the antidiabetic hormone in the period between 1889, the year in which Oskar Minkowski demonstrated that complete pancreatectomy in dogs caused diabetes, and the year 1923, the date in which the clinical use of insulin was consolidated. A main objective has been to review the controversies that followed the Nobel Prize and to outline the role of the priority rule in Science. METHODS We have considered the priority rule defined by Robert Merton in 1957, which takes into account the date of acceptance of the report of a discovery in an accredited scientific journal and/or the granting of a patent, complemented by the criteria set out by Ronald Vale and Anthony Hyman (2016) regarding the transfer of information to the scientific community and its validation by it. The awarding of the Nobel Prize in Physiology or Medicine in October 1923 has represented a frame of reference. The claims and disputes regarding the prioritization of the contributions of the main researchers in the organotherapy of diabetes have been analyzed through the study of their scientific production and the debate generated in academic institutions. MAIN RESULTS AND CONCLUSIONS (1) According to the criteria of Merton, Vale and Hyman, the priority of the discovery of the antidiabetic hormone corresponds to the investigations developed in Europe by E. Gley (1900), GL Zülzer (1908) and NC Paulescu (1920). (2) The active principle of the pancreatic extracts developed by Zülzer (acomatol), Paulescu (pancreina) and Banting and Best (insulin) was the same. (3) JB Collip succeeded in isolating the active ingredient from the pancreatic extract in January 1922, eliminating impurities to the point of enabling its use in the clinic. (4) In 1972, the Nobel Foundation modified the purpose of the 1923 Physiology or Medicine award to Banting and Macleod by introducing a new wording: "the credit for having produced the pancreatic hormone in a practical available form" (instead of "for the discovery of insulin").

Abstract
AIMS The general objective has been the historiographical investigation of the organotherapy of diabetes mellitus between 1906 and 1923 in its scientific, social and political dimensions, with special emphasis on the most relevant contributions of researchers and institutions and on the controversies generated on the priority of the "discovery" of antidiabetic hormone. METHODS We have analyzed the experimental procedures and determination of biological parameters used by researchers during the investigated period (1906-1923): pancreatic ablation techniques, induction of acinar atrophy with preservation of pancreatic islets, preparation of pancreatic extracts (PE) with antidiabetic activity, clinical chemistry procedures (glycemia, glycosuria, ketonemia, ketonuria, etc.). The field investigation has included on-site and online visits to cities, towns, buildings, laboratories, universities, museums and research centers where the reported events took place, obtaining documents, photographic images, audiovisual recordings, as well as personal interviews complementary to the documentation consulted (primary sources, critical bibliography, reference works). The documentary archival sources have been classified according to theme, including those consulted in situ with those extracted online and digitized copies received mainly by email. Among the many archives contacted, those listed below have been most useful and have been consulted on site and on repeated visits: National Library of Medicine-Historical Archives (Bethesda, MD, USA); Archives, University of Toronto and Thomas Fisher Rare Books Library (Toronto, Ontario, Canada); Francis A. County Library of Medicine, Harvard University (Boston, Mass, USA); Zentralbibliothek der Humboldt-Universität (Berlin, DE), Geheimarchiv des Preuβischen Staates (Berlin, DE); Landesamt für Bürger-und Ordnungsangelegenheiten (LABO) (Berlin, DE); Arhivele Academiei Române şi Universitǎții Carol Davila (Bucharest, RO). MAIN RESULTS AND CONCLUSIONS A) The European researchers Zülzer (Z Exp Path Ther 23:307-318, 1908) and Paulescu (CR Seances Soc Biol Fil 85:558, 1921) meet the requirements of the priority rule in the discovery of the antidiabetic hormone. B) Factors of socioeconomic and political nature related with the First World War and the inter-war period delayed the process of purification of the antidiabetic hormone in Europe. C) The Canadian scientist J. Collip, University of Alberta, temporarily assimilated to the University of Toronto, and the American chemist and researcher G. Walden, with the expert collaboration of Eli Lilly & Co., were the main authors of the purification process of the antidiabetic hormone. D) The scientific evidence, reflected in the heuristics of this research, allows to assert that the basic investigation carried out by the Department of Physiology of the University of Toronto, directed by the Scottish J. Macleod, in conjunction with the clinical research undertaken by the Department of Medicine of the University of Toronto (W. Campbell, A. Fletcher, D. Graham) made it possible in record time the successful treatment of patients with what was until then a deadly disease.

Abstract
Nearly 100 years ago, diabetes, a disease expected to reach global prevalence of at least 10% within the decade, was a fatal diagnosis. This year of 2022 marks a century since insulin, a lifesaving treatment for those living with diabetes, was purified, tested in humans, and brought to the bedside through widespread commercial production, thus saving countless lives. Insulin's arrival to the world stage was acknowledged with the 1923 Nobel Prize in Physiology or Medicine for "the discovery of insulin", the first among several Prizes awarded to honor scientific work on insulin. This initial awarding has been the subject of significant controversy since, as numerous other scientists paved the way towards the ultimate success, and priority for the true "discovery of insulin" has been argued for many other scientists. The intention and regulations around the Nobel Prize nomination and award process presented herein offer insight into the 1923 Nobel prize designation for the Toronto group, which distinguished itself in the accomplishment by their success in purifying insulin from pancreatic extract and in bringing insulin to worldwide production and the homes of those who needed it. However, a continuous, collaborative process involving contributors spanning centuries and continents was required for the development, rather than discovery, of insulin therapy and its benefits to humanity. This should be the story's enduring legacy. The prior 100 years have witnessed a series of significant innovations in insulin development and therapeutics, but both a cure for diabetes and equitable insulin access remain out of reach and require inspired attention and continuous diligent efforts.

Abstract
Discovery of insulin. If the symptoms of diabetes have been known since Antiquity, it is at the end of the 19th century that several investigators searched for the active substance of the pancreas and endeavoured to produce extracts that lowered blood and urine glucose and decreased polyuria in pancreatectomized dogs. The breakthrough came 100 years ago when the team of Frederick Banting, Charles Best and James Collip, working in the Department of Physiology, headed by John MacLeod at the University of Toronto, managed to obtain pancreatic extracts that could be used to treat patients and rescue them from the edge of death by starvation, the only treatment then available. This achievement was quickly recognized by the Nobel Prize in Physiology or Medicine to Banting and MacLeod in 1923. The discovery has had important scientific, industrial and clinical developments still efficient nowadays.

Abstract
Every young researcher dreams of making a great discovery, but few achieve it. If they do, success does not guarantee happiness. There is little satisfaction in discovering something if others get the credit, and those who achieve fame must face the 'winner's curse' of living up to their reputation. Few discoveries have been more dramatic than the isolation of insulin which, as Michael Bliss said, resembled a secular miracle. And yet, as he also pointed out, this great discovery brought little happiness to those who made it. Some were sidelined, and Banting and Best were saddled with the winner's curse. Here, we look at the ways in which a great discovery can haunt its discoverers.

Abstract
The first insulin preparation capable of consistently lowering blood glucose was developed in 1921. But 100 years later, blood glucose control with insulin in people with diabetes is nearly universally suboptimal, with essentially the same molecule still delivered by the same inappropriate subcutaneous injection route. Bypassing this route with oral administration appears to have become technologically feasible, accelerating over the past 50 years, either with packaged insulin peptides or by chemical insulin mimetics. Some of the problems of prospective unregulated absorption of insulin into the circulation from subcutaneous depots might be overcome with glucose-responsive insulins. Approaches to these problems could be modification of the peptide by adducts, or the use of nanoparticles or insulin patches, which deliver insulin according to glucose concentration. Some attention has been paid to targeting insulin preferentially to different organs, either by molecular engineering of insulin, or with adducts. But all these approaches still have problems in even beginning to match the responsiveness of physiological insulin delivery to metabolic requirements, both prandially and basally. As would be expected, for all these technically complex approaches, many examples of abandoned development can be found. Meanwhile, it is becoming possible to change the duration of action of subcutaneous injected insulin analogues to act even more rapidly for meals, and towards weekly insulin for basal administration. The state of the art of all these approaches, and the barriers to success, are reviewed here.

Abstract
BACKGROUND The discovery of insulin in 1921 and its near-immediate clinical use initiated a century of innovation. Advances extended across a broad front, from the stabilization of animal insulin formulations to the frontiers of synthetic peptide chemistry, and in turn, from the advent of recombinant DNA manufacturing to structure-based protein analog design. In each case, a creative interplay was observed between pharmaceutical applications and then-emerging principles of protein science; indeed, translational objectives contributed to a growing molecular understanding of protein structure, aggregation and misfolding. SCOPE OF REVIEW Pioneering crystallographic analyses-beginning with Hodgkin's solving of the 2-Zn insulin hexamer-elucidated general features of protein self-assembly, including zinc coordination and the allosteric transmission of conformational change. Crystallization of insulin was exploited both as a step in manufacturing and as a means of obtaining protracted action. Forty years ago, the confluence of recombinant human insulin with techniques for site-directed mutagenesis initiated the present era of insulin analogs. Variant or modified insulins were developed that exhibit improved prandial or basal pharmacokinetic (PK) properties. Encouraged by clinical trials demonstrating the long-term importance of glycemic control, regimens based on such analogs sought to resemble daily patterns of endogenous β-cell secretion more closely, ideally with reduced risk of hypoglycemia. MAJOR CONCLUSIONS Next-generation insulin analog design seeks to explore new frontiers, including glucose-responsive insulins, organ-selective analogs and biased agonists tailored to address yet-unmet clinical needs. In the coming decade, we envision ever more powerful scientific synergies at the interface of structural biology, molecular physiology and therapeutics.

Abstract
Since the discovery of insulin 100 years ago, our knowledge and understanding of diabetes have grown exponentially. Specifically, with regards to the genetics underlying diabetes risk, our discoveries have paralleled developments in our understanding of the human genome and our ability to study genomics at scale; these advancements in genetics have both accompanied and led to those in diabetes treatment. This review will explore the timeline and history of gene discovery and how this has coincided with progress in the fields of genomics. Examples of genetic causes of monogenic diabetes are presented and the continuing expansion of allelic series in these genes and the challenges these now cause for diagnostic interpretation along with opportunities for patient stratification are discussed.

Abstract
The introduction of insulin in the treatment of juvenile-onset, now type 1, diabetes mellitus transformed a rapidly fatal disease into a chronic degenerative one. During the insulin-treatment era, long-term microvascular and cardiovascular complications proved to be the bane of existence for people with type 1 diabetes, leading to blindness, kidney failure, amputations, cardiovascular disease (CVD) and premature mortality. The nascent understanding of the link between non-physiologically regulated glucose levels and these complications led to the development of new treatment tools in the 1970s and 1980s that facilitated the delivery of insulin to achieve glucose levels closer to non-diabetic levels. These therapeutic advances set the stage for definitive testing of the glucose hypothesis. The Diabetes Control and Complications Trial (DCCT), supported by the National Institute of Diabetes Digestive and Kidney Diseases, National Institutes of Health (NIH), definitively established the benefits and risks of intensive therapy that substantially lowered mean blood glucose levels, measured by HbA1c, over a mean 6.5 years of therapy. Intensive therapy in the DCCT, resulting in a mean HbA1c of ~7% (53 mmol/mol), reduced the development and progression of early microvascular and neurological complications associated with diabetes by 34-76% compared with the conventional-treatment group, which maintained an HbA1c of ~9% (75 mmol/mol). Intensive therapy was also associated with weight gain and a threefold increased risk for hypoglycaemia. At the end of the DCCT, a long-term observational follow-up study, the Epidemiology of Diabetes Interventions and Complications (EDIC) study, commenced. Despite the convergence of HbA1c levels between the two groups during EDIC, owing to the adoption of intensive therapy by the original DCCT conventional-treatment group and the return of all participants to their own healthcare providers for diabetes care, the development and progression of complications continued to be substantially less in the original intensive-treatment group vs the conventional-treatment group; this phenomenon was termed 'metabolic memory'. The DCCT demonstrated a major reduction in early-stage complications with intensive therapy and the metabolic memory phenomenon during EDIC contributed to a substantially lower burden of advanced complications over time. These included a 57% lower risk of CVD events and 33% lower rate of mortality in the original intensive-treatment group compared with the conventional-treatment group. DCCT/EDIC has ushered in the intensive-treatment era, which has been universally adopted and includes the goal of achieving HbA1c levels less than 7% (53 mmol/mol) for most patients. Although the challenge of making intensive therapy (with the aim of achieving normoglycaemia) as widely accessible and safe as possible remains, continuing improvements in insulin therapy 100 years after its introduction promise a brighter future for people with type 1 diabetes.

Abstract
The dawn of the insulin era can be placed in 1921, when Banting and Best started their experiments which led, a year later, to the successful treatment of diabetes. They were preceded by the discoveries of the pancreatic cause of diabetes by Minkowski and von Mering in 1889 and of the islets by Paul Langerhans in 1869. The achievement of the first targeted treatment in medical history was a landmark of medical progress. However, it was accompanied by a mixture of human greatness and misery. Genius and recklessness, ambition and deception, camaraderie and rivalry, selflessness and pursuit of glory went along with superficial search of the existing literature, poor planning, faulty interpretation of results, failure to reproduce them, and misquoting of reports from other laboratories. Then as now, such faults surface whenever human nature aims to push forward the boundaries of knowledge and pose a real challenge in today's world, as the scientific method strives to keep healthy in the face of growing anti-scientific feelings.

Abstract
At 2:00 h on Oct 31, 1920, Frederick G Banting, a surgeon practising in London, ON, Canada, conceived an idea to isolate the internal secretion of the pancreas. The following week, he met with noted scientist John J R Macleod in Toronto, ON, Canada, and they developed a research plan. By August, 1921, Banting and his student assistant Charles H Best had prepared an effective extract from a canine pancreas. In January, 1922, biochemist James B Collip isolated insulin that was sufficiently pure for human use. On Oct 25, 1923, Banting and Macleod received the Nobel Prize in Physiology or Medicine for the discovery of insulin. Here, we recount the most relevant events before and after the fateful early morning of Oct 31, 1920, which culminated in the discovery and clinical use of insulin.

Abstract
In 1936, the journalist Hannah Lees published "Two Million Tightrope Walkers," drawing attention to the significant number of people in the United States estimated to have diabetes. Focusing on how people with diabetes should live, she emphasized the importance of recording the exact values of everything they ate and avoiding all "riotous living" lest they be unable to keep careful measurements of calories, insulin, and sleep. Employing two meanings of measured - as counted and as moderate - Lees was doing more than communicating how someone might control their disease; she was also calling for a "controlled and self-reliant citizenry." Indeed, Lees insisted that diabetics who followed a regime of measurement "make a good deal better citizens than the average." Drawing on the writings of Lees and other social commentators, I explore the link between biometrics, citizenship, and diabetes in the United States in the interwar years. In particular, I look at how this disease came to symbolize both the regimes of discipline thought to be necessary in a society moving to consumption as its economic motor, and the fears of what could happen if consumption ran amok. Biometrics, I argue, offered clinicians and patients a potent tool for measuring deviance and, potentially, for restoring a person to the "norm."

Abstract
The year 2020 marks the 25th anniversary of the Psychosocial Aspects of Diabetes (PSAD) study group of the European Association for the Study of Diabetes. At the time, psychosocial diabetes research in Europe was steadily growing, but not well recognized. By establishing an official European Association for the Study of Diabetes study group, PSAD, for which purpose some hurdles had to be overcome, diabetes psychology became more visible and accessible to the scientific diabetes community. Over the years the PSAD study group has been successful in promoting the quality of research in the field through scientific meetings, mentoring, postgraduate education and publications. Looking back we can conclude that starting the PSAD study group signified an important moment in time, where researchers were joining forces to further the quality of the science, raise awareness of the importance of psychosocial aspects and promote the dissemination of psychological interventions in diabetes care.

Abstract
Behaviour is central to the management of diabetes, both for people living with diabetes and for healthcare professionals delivering evidence-based care. This review outlines the evolution of behavioural science and the application of theoretical models in diabetes care over the past 25 years. There has been a particular advancement in the development of tools and techniques to support researchers, healthcare professionals and policymakers in taking a theory-based approach, and to enhance the development, reporting and replication of successful interventions. Systematic guidance, theoretical frameworks and lists of behavioural techniques provide the tools to specify target behaviours, identify why ideal behaviours are not implemented, systematically develop theory-based interventions, describe intervention content using shared terminology, and evaluate their effects. Several examples from a range of diabetes-related behaviours (clinic attendance, self-monitoring of blood glucose, retinal screening, setting collaborative goals in diabetes) and populations (people with type 1 and type 2 diabetes, healthcare professionals) illustrate the potential for these approaches to be widely translated into diabetes care. The behavioural science approaches outlined in this review give healthcare professionals, researchers and policymakers the tools to deliver care and design interventions with an evidence-based understanding of behaviour. The challenge for the next 25 years is to refine the tools to increase their use and advocate for the role of theoretical models and behavioural science in the commissioning, funding and delivery of diabetes care.

Abstract
AIM Motivation to take up and maintain a healthy lifestyle is key to diabetes prevention and management. Motivations are driven by factors on the psychological, biological and environmental levels, which have each been studied extensively in various lines of research over the past 25 years. Here, we analyse and reflect on current and emerging knowledge on motivation in relation to lifestyle behaviours, with a focus on people with diabetes or obesity. Structured according to psychological, (neuro-)biological and broader environmental levels, we provide a scoping review of the literature and highlight frameworks used to structure motivational concepts. Results are then put in perspective of applicability in (clinical) practice. RESULTS Over the past 25 years, research focusing on motivation has grown exponentially. Social-cognitive and self-determination theories have driven research on the key motivational concepts 'self-efficacy' and 'self-determination'. Neuro-cognitive research has provided insights in the processes that are involved across various layers of a complex cortical network of motivation, reward and cognitive control. On an environmental - more upstream - level, motivations are influenced by characteristics in the built, social, economic and policy environments at various scales, which have provided entry points for environmental approaches influencing behaviour. CONCLUSIONS Current evidence shows that motivation is strongly related to a person's self-efficacy and capability to initiate and maintain healthy choices, and to a health climate that supports autonomous choices. Some approaches targeting motivations have been shown to be promising, but more research is warranted to sustainably reduce the burden of diabetes in individuals and populations.

Abstract
AIMS To summarize the history, development and efficacy of diabetes self-management education on glycaemic control and mental health in adults and children or adolescents with type 1 diabetes and people with type 2 diabetes. A further aim was to review the status of implementation of diabetes self-management education into routine care and outline current gaps in implementation and research. METHODS We searched PubMed and Google scholar for German- and English-language articles regarding diabetes self-management education, glycaemic control and mental health, and restricted this search to meta-analyses. RESULTS Diabetes education has evolved from a compliance- and knowledge-oriented approach to an empowerment- and self-management-oriented approach. Diabetes self-management education seems to have a greater impact on glycaemic outcomes than on mental health outcomes, but the latter are rarely assessed. Technological development and digitalization can provide chances and challenges for diabetes self-management education. Digital solutions show promising results and great potential for improving the efficacy of diabetes self-management education further and providing ongoing support. The implementation of diabetes self-management education into routine clinical care frequently remains a challenge. CONCLUSION Diabetes self-management education has been acknowledged as an essential part of diabetes therapy; however, current gaps regarding the efficacy of diabetes self-management education on mental health, and the need for education on the use of diabetes technology, are future avenues for research.

Abstract
Over the past 25 years, there has been significant acknowledgement of the importance of assessing the impact of diabetes on quality of life. Yet, despite the development of several diabetes-specific quality of life measures, the challenges we faced in 1995 remain. There is little consensus on the definition of quality of life because of the complexity and subjectivity of the concept. General quality of life comprises several domains of life, and these are highly individualized. Assessing the impact of diabetes on these life domains adds to the complexity. While comprehensive diabetes-specific quality-of-life measures typically increase respondent burden, brief questionnaires may not capture all relevant/important domains. Today, the lack of resolution of these challenges may explain why the impact of diabetes on quality of life is not systematically assessed in research or clinical care. Few researchers report detailed rationales for assessment, there is often a mismatch between the concept of interest and the measure selected, and data are misinterpreted as assessing the impact of diabetes on quality of life when, in reality, related but distinct constructs have been assessed, such as diabetes distress, treatment satisfaction or health status. While significant efforts are being made to increase routine monitoring of psychological well-being and understand the lived experience, no guidelines currently recommend routine clinical assessment of diabetes-specific quality of life, and there is no consensus on which questionnaire(s) to use. The gaps identified in this review need urgent attention, starting with recognition that assessment of diabetes-specific quality of life is as important as biomedical markers, if we are to improve the lives of people with diabetes.

Abstract
We review the past 25 years of research addressing challenges people living with diabetes experience in their daily lives related to social contexts, i.e. in their family, at work and in society at large, and identify research gaps. We found that young people with diabetes, as they develop through to adulthood, are exposed to considerable risks to their physical and mental health. Family-system interventions have had mixed outcomes. Research in this area would benefit from attention to ethnic/cultural diversity, and involving fathers and other family members. In adults with diabetes, social support relates to better diabetes outcomes. While family member involvement in care is likely to affect health and psychosocial outcomes of the person with diabetes, key elements and mediators of effective family interventions need to be identified. The challenges of diabetes management at work are under-researched; distress and intentional hyperglycaemia are common. When depression is comorbid with diabetes, there are increased work-related risks, e.g. unemployment, sickness absence and reduced income. Research to support people with diabetes at work should involve colleagues and employers to raise awareness and create supportive environments. Stigma and discrimination have been found to be more common than previously acknowledged, affecting self-care, well-being and access to health services. Guidance on stigma-reducing choice of language has been published recently. Resilience, defined as successful adaptation to adversity such as stigma and discrimination, requires studies relevant to the specific challenges of diabetes, whether at diagnosis or subsequently. The importance of the social context for living well with diabetes is now fully recognized, but understanding of many of the challenges, whether at home or work, is still limited, with much work needed to develop successful interventions.

Abstract
In past decades, a rapid evolution of diabetes technology led to increased popularity and use of continuous glucose monitoring (CGM) and continuous subcutaneous insulin infusion (CSII) in the ambulatory setting for diabetes management, and recently, the artificial pancreas became available. Efforts to translate this technology to the hospital setting have shown accuracy and reliability of CGM, safety of CSII in appropriate populations, improvement of inpatient glycemic control with computerized glycemic management systems, and feasibility of inpatient CGM-CSII closed-loop systems. Several ongoing studies are focusing on continued translation of this technology to improve glycemic control and outcomes in hospitalized patients.

Abstract
BACKGROUND Describing the prevalence and trends of cardiometabolic risk factors that are associated with non-communicable diseases (NCDs) is crucial for monitoring progress, planning prevention, and providing evidence to support policy efforts. We aimed to analyse the transition in body-mass index (BMI), obesity, blood pressure, raised blood pressure, and diabetes in the Americas, between 1980 and 2014. METHODS We did a pooled analysis of population-based studies with data on anthropometric measurements, biomarkers for diabetes, and blood pressure from adults aged 18 years or older. A Bayesian model was used to estimate trends in BMI, raised blood pressure (systolic blood pressure ≥140 mm Hg or diastolic blood pressure ≥90 mm Hg), and diabetes (fasting plasma glucose ≥7·0 mmol/L, history of diabetes, or diabetes treatment) from 1980 to 2014, in 37 countries and six subregions of the Americas. FINDINGS 389 population-based surveys from the Americas were available. Comparing prevalence estimates from 2014 with those of 1980, in the non-English speaking Caribbean subregion, the prevalence of obesity increased from 3·9% (95% CI 2·2-6·3) in 1980, to 18·6% (14·3-23·3) in 2014, in men; and from 12·2% (8·2-17·0) in 1980, to 30·5% (25·7-35·5) in 2014, in women. The English-speaking Caribbean subregion had the largest increase in the prevalence of diabetes, from 5·2% (2·1-10·4) in men and 6·4% (2·6-10·4) in women in 1980, to 11·1% (6·4-17·3) in men and 13·6% (8·2-21·0) in women in 2014). Conversely, the prevalence of raised blood pressure has decreased in all subregions; the largest decrease was found in North America from 27·6% (22·3-33·2) in men and 19·9% (15·8-24·4) in women in 1980, to 15·5% (11·1-20·9) in men and 10·7% (7·7-14·5) in women in 2014. INTERPRETATION Despite the generally high prevalence of cardiometabolic risk factors across the Americas, estimates also showed a high level of heterogeneity in the transition between countries. The increasing prevalence of obesity and diabetes observed over time requires appropriate measures to deal with these public health challenges. Our results support a diversification of health interventions across subregions and countries. FUNDING Wellcome Trust.

Abstract
The article reviews the life and work of an outstanding Russian pharmacologist Professor Nikolai Kravkov (1865-1924). Among his many scientific achievements, he worked on an extract from the pancreas of animals in the early 1920s and was successful in isolating the internal secretion, which he named "pancreotoxine." This reduced blood glucose levels in animals and diabetic humans. Kravkov's work on the isolation of pancreotoxine was going on coincidentally with F. Banting's and C. Best's research of insulin, but their methods of isolation of the hormone were quite different.

Abstract
In classic accounts of the development of modern medicine in Europe and North America, the sick person is often portrayed as having a history of disappearance with the rise of the objectified body of the modern patient. To this account, sociologists and historians of medicine have added another for the period after 1950, in which the patient as subjective person "reappears" in medical discourse. However, despite histories of practice and identity revising narratives of disappearance, the patient's reappearance has largely escaped further assessment. Using an analysis of dietary management in twentieth-century British diabetes care, this article challenges accounts of this reappearance in three ways. Firstly, it argues that discursive interest in the social and psychological aspects of care emerged earlier than suggested. Secondly, it grounds such interest in reconfigured institutional arrangements that were initially designed to rationalize care and improve efficiency. Finally, it argues that patients regularly exceeded the efforts of even an expanded management regime to normalize and regulate life. Food planning, preparation, and consumption continued to sit at the nexus of competing demands that mediated medical efforts to cultivate governable selves and bodies.

Abstract
The present chapter deals with the contribution of Professor Paul A. Bastenie, as Chief of the Department of Medicine of the Saint-Pierre Hospital and Director of the Laboratory of Experimental Medicine at Brussels Free University, in the field of diabetes with emphasis on the role of insulin in glucose homeostasis. The knowledge and experimental work under consideration is covering the period from 1955 to 1974. They entail not only three treatises contributed by Bastenie but also fundamental and clinical investigations, such as those presented in eight doctoral dissertations submitted for aggregation examination at Brussels Free University. These theses are dealing with the measurement of glucose assimilation (V. Conard), the measurement of insulin activity in men (J.R.M. Franckson), the mechanisms of action of hypoglycemic drugs (R. Bellens), the study of energy metabolism in children (H. Loeb), the study of insulin secretion in vitro (W. Malaisse), the distribution of insulin in body fluids as influenced by the permeability and structure of blood capillaries (E. Rasio), the regulation of the extra-hepatic metabolism of ketone bodies in anesthetized dogs (E.O. Balasse) and the use of radioiodinated insulin as tracers in biology (H.A. Ooms).

Abstract
UNLABELLED The purpose of this article is to describe the research of Nicolae Constantin Paulescu and to emphasize his role in the discovery of insulin. METHODS We made a thorough review of the literature and research in the Romanian Academy Archive in order to find adequate references. RESULTS In 1912 N.C. Paulescu analysed the clinical and biochemical alterations in diabetic patients and in dogs after performing a pancreatectomy, that apart hyperglycemia and glycosuria (carbohydrate metabolism), had noted also changes in lipid and protein metabolism. In 1916 he started the experiments with a pancreas extract obtained by his original method, that was injected intravenously to the diabetic dogs. The results of his first experiments showed: "The pancreatic extract injected into a peripheral vein produce: 1) A diminution and even a temporary suppression of diabetic hyperglycemia, which may be replaced by hypoglycemia; 2) A diminution or even temporary suppression of glycosuria; 3) A diminution of blood urea; 4) A diminution of urinary urea. In other words, the intravenous injection of the pancreatic extract has as effect the disappearance of diabetic symptoms. The attenuation of the diabetic syndrome begins immediately after the injection. It reaches a maximum after 2 hours,- and it lasts for about 12 hours". He concluded as such: "This discovery,- which sheds a bright light over the pathogenesis of diabetes gives us also the key for the treatment of this syndrome". In 1921, Paulescu had published extensively his data in two outstanding French journals 8 months before the first publication of Banting and Best from February 1922. It is clear that insulin has been discovered in Europe. CONCLUSION Paulescu thought that a new hormone - Pancreine, that he discovered is the key element in the treatment of diabetes, but his outstanding research was unfairly neglected.

Abstract
In Mexico, as in the entire Western world, during the 19th century and the beginnings of the 20th century, medical knowledge developed in a remarkable way and the case of diabetes mellitus was not the exception. This situation, which arose on the basis of the antique paradigm, and which in turn was overthrown by the positivism as the emergent paradigm (with its clinical and anatomical, as well as physiopathological and etiopathological viewpoints), was reflected during the 19th the century through its actors and the communications that opened the access of Mexican medicine to the modernity.

Abstract
Recent studies suggest that prevalence of diagnosed diabetes in the United States reached a plateau or slowed around 2008, and that this change coincided with obesity plateaus and increases in physical activity. However, national estimates can obscure important variations in geographic subgroups. We examine whether a slowing or leveling off in diagnosed diabetes, obesity, and leisure time physical inactivity prevalence is also evident across the 3143 counties of the United States. We used publicly available county estimates of the age-adjusted prevalence of diagnosed diabetes, obesity, and leisure-time physical inactivity, which were generated by the Centers for Disease Control and Prevention (CDC). Using a Bayesian multilevel regression that included random effects by county and year and applied cubic splines to smooth these estimates over time, we estimated the average annual percentage point change (APPC) from 2004 to 2008 and from 2008 to 2012 for diabetes, obesity, and physical inactivity prevalence in each county. Compared to 2004-2008, the median APPCs for diabetes, obesity, and physical inactivity were lower in 2008-2012 (diabetes APPC difference = 0.16, 95%CI 0.14, 0.18; obesity APPC difference = 0.65, 95%CI 0.59, 0.70; physical inactivity APPC difference = 0.43, 95%CI 0.37, 0.48). APPCs and APPC differences between time periods varied among counties and U.S. regions. Despite improvements, levels of these risk factors remained high with most counties merely slowing rather than reversing, which suggests that all counties would likely benefit from reductions in these risk factors. The diversity of trajectories in the prevalence of these risk factors across counties underscores the continued need to identify high risk areas and populations for preventive interventions. Awareness of how these factors are changing might assist local policy makers in targeting and tracking the impact of efforts to reduce diabetes, obesity and physical inactivity.

Abstract
The impact of a specially designed patient education program upon the diabetes-related knowledge and compliance of insulin dependent diabetic patients was investigated. The program consisted of an audiovisual presentation, illustrated handout material, and pharmacist-patient counseling. Based on statistical considerations, 65 eligible patients were assigned systematically to a control group (Group I) and a study group (Group II) and were evaluated for compliance following a standardized protocol. Immediately following the interview, Group II patients were instructed utilizing the patient education program. Scores for initial and final evaluations of knowledge and compliance were compared using appropriate statistical procedures. The program was successful in producing improvements in both knowledge and compliance but a need for individualization of patient education efforts was indicated. Significant improvements in compliance were not observed among patients older than the mean age for study patients and those with diabetes complicated by cardiovascular and hypertensive disease.

Abstract
This article examines Robbie McCauley's Sugar, focusing on how this solo performance work opens up discursive spaces for a range of voices and perspectives. I argue that the ideas expressed in Sugar work as a type of vernacular theorizing, questioning the means by which certain perspectives and ways of knowing are valued over others. In the conclusion, I suggest how Sugar could serve as a model for health professionals involved in the fight again diabetes, as it opens up opportunities for dialogue and makes visible the processual nature of people's attempts to make sense of the disease.
