    8076 Advancing Career Development of Physician-Scientists Engaged in Diabetes Research: Insights into the National K12 DiabDocs Program
    (Oxford University Press, 2024-10-05) Dasani, Komal D.; Bishop, Franziska K.; Golden, Sherita H.; Laffel, Lori M.; Mirmira, Raghavendra G.; Steck, Andrea K.; Willi, Steven M.; Maahs, David M.; DiMeglio, Linda A.; Pediatrics, School of Medicine
    Background: In July 2022 the NIH established a multi-center National K12 “Diabetes-Docs: Physician-Scientist Career Development Program” (DiabDocs) to support mentored research experiences and tailored career development training for cohorts of physician scientists focused on diabetes research. DiabDocs scholars are board-certified or board-eligible physicians with training in pediatric or adult endocrinology or in another area tied to diabetes research and care. The program addresses the shortage of physicians engaged in diabetes research and is open to scholars at any eligible institution in the United States. Methods: The DiabDocs program was implemented by two multi-center Program Directors (MPD), in collaboration with an Executive Leadership Committee (ELC) comprised of experienced basic science and clinical/translational physician-scientists. Additional faculty from 19 different institutions have engaged in advisory and reviewer roles. The program solicits Letters of Intent (LOIs) annually from interested candidates followed by invitations for full applications; a program retreat features educational workshops and diversity training; and a Study Section selects Scholars. Currently, the program is in its third recruitment cycle for additional scholars to start Summer 2024. Additional career development programming is available through a series of interactive webinars. The program also has a strong commitment to diversity, equity, and inclusion, including a “DiabDiversity” program to support in-person engagement in DiabDocs experiences by under-represented in medicine trainees. Results: After two successful recruitment cycles in 2022-2023 that reviewed 24 LOIs, 11 scholars were selected. The funded scholars (6 Adult and 5 Pediatric Endocrinologists) include 3 individuals self-identifying as underrepresented in medicine and 7 females. For the 2023 application cycle, 24 LOIs were received (11 from Adult and 9 from Pediatric Endocrinology, 2 in combined Pediatric/Adult Endocrinology, and 2 from other specialties). Conclusions: The DiabDocs program aims to identify, recruit, and support outstanding early career physician scientists. The program provides a national network with resources for protected research time, career development programs, and national mentorship to develop cohorts of skilled professionals contributing to the advancement of diabetes research.

    Given the proven benefits of screening to reduce diabetic ketoacidosis (DKA) likelihood at the time of stage 3 type 1 diabetes diagnosis, and emerging availability of therapy to delay disease progression, type 1 diabetes screening programmes are being increasingly emphasised. Once broadly implemented, screening initiatives will identify significant numbers of islet autoantibody-positive (IAb+) children and adults who are at risk of (confirmed single IAb+) or living with (multiple IAb+) early-stage (stage 1 and stage 2) type 1 diabetes. These individuals will need monitoring for disease progression; much of this care will happen in non-specialised settings. To inform this monitoring, JDRF in conjunction with international experts and societies developed consensus guidance. Broad advice from this guidance includes the following: (1) partnerships should be fostered between endocrinologists and primary-care providers to care for people who are IAb+; (2) when people who are IAb+ are initially identified there is a need for confirmation using a second sample; (3) single IAb+ individuals are at lower risk of progression than multiple IAb+ individuals; (4) individuals with early-stage type 1 diabetes should have periodic medical monitoring, including regular assessments of glucose levels, regular education about symptoms of diabetes and DKA, and psychosocial support; (5) interested people with stage 2 type 1 diabetes should be offered trial participation or approved therapies; and (6) all health professionals involved in monitoring and care of individuals with type 1 diabetes have a responsibility to provide education. The guidance also emphasises significant unmet needs for further research on early-stage type 1 diabetes to increase the rigour of future recommendations and inform clinical care.

    COVID-19 and Children With Diabetes-Updates, Unknowns, and Next Steps: First, Do No Extrapolation
    (American Diabetes Association, 2020-09-04) DiMeglio, Linda A.; Albanese-O'Neill, Anastasia; Muñoz, Cynthia E.; Maahs, David M.; Pediatrics, School of Medicine
    We are in a place where the only certainty is continued uncertainty about the course of this pandemic. We thank our international pediatric diabetes colleagues and hope their work spurs others to collaborate internationally to gather more evidence. We call on our community to articulate needs and refine recommended actions. As federal diabetes funding is uncertain and many not-for-profit organizations, including the American Diabetes Association and JDRF, announce cuts in funding opportunities and staffing, we must galvanize the pediatric diabetes volunteer community to join our efforts. We must continue to be humble and patient about what we know and advocate strenuously for coordinated, expanded, and responsive public health systems to support youth with both type 1 and type 2 diabetes.

    The Evolution of Hemoglobin A1c Targets for Youth With Type 1 Diabetes: Rationale and Supporting Evidence
    (American Diabetes Association, 2021) Redondo, Maria J.; Libman, Ingrid; Maahs, David M.; Lyons, Sarah K.; Saraco, Mindy; Reusch, Jane; Rodriguez, Henry; DiMeglio, Linda A.; Pediatrics, School of Medicine
    The American Diabetes Association 2020 Standards of Medical Care in Diabetes (Standards of Care) recommends a hemoglobin A1c (A1C) of <7% (53 mmol/mol) for many children with type 1 diabetes (T1D), with an emphasis on target personalization. A higher A1C target of <7.5% may be more suitable for youth who cannot articulate symptoms of hypoglycemia or have hypoglycemia unawareness and for those who do not have access to analog insulins or advanced diabetes technologies or who cannot monitor blood glucose regularly. Even less stringent A1C targets (e.g., <8%) may be warranted for children with a history of severe hypoglycemia, severe morbidities, or short life expectancy. During the "honeymoon" period and in situations where lower mean glycemia is achievable without excessive hypoglycemia or reduced quality of life, an A1C <6.5% may be safe and effective. Here, we provide a historical perspective of A1C targets in pediatrics and highlight evidence demonstrating detrimental effects of hyperglycemia in children and adolescents, including increased likelihood of brain structure and neurocognitive abnormalities, microvascular and macrovascular complications, long-term effects, and increased mortality. We also review data supporting a decrease over time in overall severe hypoglycemia risk for youth with T1D, partly associated with the use of newer insulins and devices, and weakened association between lower A1C and severe hypoglycemia risk. We present common barriers to achieving glycemic targets in pediatric diabetes and discuss some strategies to address them. We aim to raise awareness within the community on Standards of Care updates that impact this crucial goal in pediatric diabetes management.

    The obesity epidemic in 32,936 youth with type 1 diabetes (T1D) in the German/Austrian DPV and US T1D Exchange (T1DX) registries
    (Elsevier, 2015-09) DuBose, Stephanie N.; Hermann, Julia M.; Tamborlane, William V.; Beck, Roy W.; Dost, Axel; DiMeglio, Linda A.; Schwab, Karl Otfried; Holl, Reinhard W.; Hofer, Sabine E.; Maahs, David M.; Department of Pediatrics, IU School of Medicine
    Objective To examine the current extent of the obesity problem in 2 large pediatric clinical registries in the US and Europe and to examine the hypotheses that increased body mass index (BMI) z-scores (BMIz) are associated with greater hemoglobin A1c (HbA1c) and increased frequency of severe hypoglycemia in youth with type 1 diabetes (T1D). Study design International (World Health Organization) and national (Centers for Disease Control and Prevention/German Health Interview and Examination Survey for Children and Adolescents) BMI references were used to calculate BMIz in participants (age 2-<18 years and ≥1 year duration of T1D) enrolled in the T1D Exchange (n = 11 435) and the Diabetes Prospective Follow-up (n = 21 501). Associations between BMIz and HbA1c and severe hypoglycemia were assessed. Results Participants in both registries had median BMI values that were greater than international and their respective national reference values. BMIz was significantly greater in the T1D Exchange vs the Diabetes Prospective Follow-up (P < .001). After stratification by age-group, no differences in BMI between registries existed for children 2-5 years, but differences were confirmed for 6- to 9-, 10- to 13-, and 14- to 17-year age groups (all P < .001). Greater BMIz were significantly related to greater HbA1c levels and more frequent occurrence of severe hypoglycemia across the registries, although these associations may not be clinically relevant. Conclusions Excessive weight is a common problem in children with T1D in Germany and Austria and, especially, in the US. Our data suggest that obesity contributes to the challenges in achieving optimal glycemic control in children and adolescents with T1D.

    State of Type 1 Diabetes Management and Outcomes from the T1D Exchange in 2016–2018
    (Liebert, 2019-02) Foster, Nicole C.; Beck, Roy W.; Miller, Kellee M.; Clements, Mark A.; Rickels, Michael R.; DiMeglio, Linda A.; Maahs, David M.; Tamborlane, William V.; Bergenstal, Richard; Smith, Elizabeth; Olson, Beth A.; Garg, Satish K.; Pediatrics, School of Medicine
    Objective: To provide a snapshot of the profile of adults and youth with type 1 diabetes (T1D) in the United States and assessment of longitudinal changes in T1D management and clinical outcomes in the T1D Exchange registry. Research Design and Methods: Data on diabetes management and outcomes from 22,697 registry participants (age 1–93 years) were collected between 2016 and 2018 and compared with data collected in 2010–2012 for 25,529 registry participants. Results: Mean HbA1c in 2016–2018 increased from 65 mmol/mol at the age of 5 years to 78 mmol/mol between ages 15 and 18, with a decrease to 64 mmol/mol by age 28 and 58–63 mmol/mol beyond age 30. The American Diabetes Association (ADA) HbA1c goal of <58 mmol/mol for youth was achieved by only 17% and the goal of <53 mmol/mol for adults by only 21%. Mean HbA1c levels changed little between 2010–2012 and 2016–2018, except in adolescents who had a higher mean HbA1c in 2016–2018. Insulin pump use increased from 57% in 2010–2012 to 63% in 2016–2018. Continuous glucose monitoring (CGM) increased from 7% in 2010–2012 to 30% in 2016–2018, rising >10-fold in children <12 years old. HbA1c levels were lower in CGM users than nonusers. Severe hypoglycemia was most frequent in participants ≥50 years old and diabetic ketoacidosis was most common in adolescents and young adults. Racial differences were evident in use of pumps and CGM and HbA1c levels. Conclusions: Data from the T1D Exchange registry demonstrate that only a minority of adults and youth with T1D in the United States achieve ADA goals for HbA1c.
