RESUMO
OBJECTIVE: To compare postprandial glucose excursions following a bolus with inhaled technosphere insulin (TI) or subcutaneous rapid-acting analog (RAA) insulin. RESEARCH DESIGN AND METHODS: A meal challenge was completed by 122 adults with type 1 diabetes who were using multiple daily injections (MDI), a nonautomated pump, or automated insulin delivery (AID) and who were randomized to bolus with their usual RAA insulin (n = 61) or TI (n = 61). RESULTS: The primary outcome, the treatment group difference in area under the curve for glucose >180 mg/dL over 2 h, was less with TI versus RAA (adjusted difference -12 mg/dL, 95% CI -22 to -2, P = 0.02). With TI, the glucose excursion was smaller (P = 0.01), peak glucose lower (P = 0.01), and time to peak glucose shorter (P = 0.006). Blood glucose <70 mg/dL occurred in one participant in each group. CONCLUSIONS: Postmeal glucose excursion was smaller with TI than with RAA insulin in a cohort that included both AID and MDI users.
RESUMO
BACKGROUND: Recent advancements in diabetes technology have significantly improved Type 1 diabetes (T1D) management, but disparities persist, particularly in the adoption of automated insulin delivery (AID) systems within minoritized communities. We aimed to improve patient access to AID system training and overcome clinical inertia to referral. METHODS: We report on a transformative program implemented at Boston Medical Center, the largest safety-net hospital in New England, aimed at reducing disparities in AID system utilization. We employed a multidisciplinary team and quality improvement principles to identify barriers and develop solutions. Strategies included increasing access to diabetes educators, creating a referral system, and developing telemedicine education classes. We also made efforts to raise clinician awareness and confidence in recommending AID therapy. RESULTS: At baseline, 13.5% of our clinic T1D population was using an insulin pump. The population referred included 97 people with T1D (49% female, mean A1c 8.7%, 68% public insurance beneficiaries, 25% Hispanic and 25% non-Hispanic Black). Results from the first year showed a 166% increase in AID system use rates, with 64% of referred patients starting on AID. Notably, 78% of patients with A1c >8.5% adopted AID systems, addressing a gap in representation observed in clinical efficacy trials. The initiative successfully narrowed disparities in AID use among minoritized populations. CONCLUSIONS: The program's success among minoritized patients underscores the significance of tailored, collaborative, team-based care and targeted educational initiatives. Our experience provides a foundation for future efforts to ensure equitable access to diabetes technologies, emphasizing the potential of local quality improvement interventions.

Individuals living with type 1 diabetes (T1D) from medically underserved communities have poorer health outcomes. Efforts to improve outcomes include a focus on team-based care, activation of behavior change, and enhancing self-management skills and practices. Advanced diabetes technologies are part of the standard of care for adults with T1D. However, health care providers often carry implicit biases and may be uncomfortable with recommending technologies to patients who have traditionally been excluded from efficacy trials or have limited real-world exposure to devices. We review the literature on this topic and provide an approach to address these issues in clinical practice.

The Kidney Precision Medicine Project (KPMP) aims to create a kidney tissue atlas, define disease subgroups, and identify critical cells, pathways, and targets for novel therapies through molecular investigation of human kidney biopsies obtained from participants with acute kidney injury (AKI) or chronic kidney disease (CKD). We present the case of a 66-year-old woman with diabetic kidney disease who underwent a protocol KPMP kidney biopsy. Her clinical history included diabetes mellitus complicated by neuropathy and eye disease, increased insulin resistance, hypertension, albuminuria, and relatively preserved glomerular filtration rate (early CKD stage 3a). The patient's histopathology was consistent with diabetic nephropathy and arterial and arteriolar sclerosis. Three-dimensional, immunofluorescence imaging of the kidney biopsy specimen revealed extensive peri-glomerular neovascularization that was underestimated by standard histopathologic approaches. Spatial transcriptomics was performed to obtain gene expression signatures at discrete areas of the kidney biopsy. Gene expression in the areas of glomerular neovascularization revealed increased expression of genes involved in angiogenic signaling, proliferation and survival of endothelial cells, as well as new vessel maturation and stability. This molecular correlation provides additional insights into the development of kidney disease in patients with diabetes and spotlights how novel molecular techniques employed by the KPMP can supplement and enrich the histopathologic diagnosis obtained from a kidney biopsy.
RESUMO
Background: In this proof-of-concept study, we evaluated if monogenic diabetes resulting from mutations of the HNF-1α gene (HNF1A-MODY) has a distinctive continuous glucose monitoring (CGM) glucotype, in comparison to type 1 diabetes (T1D). Methods: Using CGM data from 5 subjects with HNF1A-MODY and 115 subjects with T1D, we calculated multiple glucose metrics, including measures of within- and between-day variability (such as coefficient variation for each hour [CVb_1h]). Results: The MODY and T1D cohorts had minimum CVb_1h of 11.3 ± 4.4 and 18.0 ± 4.9, respectively (P = .02) and maximum CVb_1h of 33.9 ± 5.0 and 50.3 ± 10, respectively (P < .001). All subjects with HNF1A-MODY had a minimum %CVb_1h ≤ 17.3% and maximum %CVb_1h ≤ 37.1%. In contrast, only 12 of 115 subjects with T1D had both a minimum and maximum %CVb_1h below these thresholds (P < .001). Conclusion: HNF1A- MODY is characterized by a low hourly, between-day glucose variability. CGM-derived glucose metrics may have potential applicability for screening for atypical diabetes phenotypes in the T1D population.

BACKGROUND: Despite increases in continuous glucose monitor (CGM) and insulin pump use in adults with diabetes, there is room for expansion. Technology adoption may be influenced by the training environment and fellowship education. However, little is known about adult endocrinology trainee comfort with, understanding of, or methods by which trainees receive education about diabetes technology. METHODS: Mixed methods, sequential explanatory evaluation using survey and semi-structured interviews of endocrinology trainees and fellowship leadership in Accreditation Council for Graduate Medical Education (ACGME)-accredited adult endocrinology fellowship programs to assess trainee and leadership comfort with, perceived knowledge of, and current methods for diabetes technology education. RESULTS: Seventy-seven respondents completed the survey. The majority of training programs have curricula for training on insulin pumps (74%) and CGM (75.3%); 52% of fellows felt curricula are adequate. First- and second-year fellows were more comfortable with CGM than insulin pump use. Only half of third-year fellows felt comfortable with starting insulin pump therapy or recommending insulin dose adjustments based on CGM rate of change arrows. Qualitative interviews identified the importance of both direct instruction and experiential learning in diabetes technology education. CONCLUSIONS: Almost half of trainees feel that curricula for learning to use and manage insulin pumps and CGM are inadequate and feel uncomfortable with critical aspects of technology use, demonstrating the need for increased attention to trainee education in the use of diabetes technology. Based on a better understanding of current and preferred methods for instruction, this study provides direction for future development of initiatives to improve fellow education in this field.

There are limited tools to address equity in diabetes research and clinical trials. The T1D Exchange has established a 10-step equity framework to advance equity in diabetes research. Herein, the authors outline this approach and expand on its practical application.
RESUMO
Background: Continuous glucose monitoring (CGM) has been increasingly shown to be beneficial in patients with both types 1 and 2 diabetes using insulin. Despite this, challenges remain in obtaining coverage for these devices. We sought to define the process of initiation of CGM and better understand factors associated with successful initiation. Methods: A single-center retrospective cohort study of 271 patients seen over a 3-year period from 2017 to 2020 in the adult endocrinology clinic at Boston Medical Center who were prescribed CGM was performed. The primary outcome was time to CGM initiation. Secondary outcomes included factors associated with initiation and continued use of CGMs and glycemic control. Results: Obtaining CGM through pharmacy benefit was significantly faster than through durable medical equipment companies (78 days vs. 152 days, P < 0.0001). Factors associated with initiation of CGM were younger age, private insurance, and education with a clinical diabetes educator. Identifying as black or Hispanic was significantly associated with decreased initiation of CGM. Glycemic control as represented by hemoglobin A1c improved in patients initiated on CGM from 9.06% to 8.22% (P < 0.001). Conclusion: Prescribing CGM as a pharmacy benefit significantly reduces the time to initiation, but on average, still takes several months, delaying potentially life-saving care for patients living with diabetes. Barriers to CGM initiation must be addressed to ensure timely delivery of optimal care to our patients.

This article describes the evolution of the Type 1 Diabetes Exchange Quality Improvement Collaborative (T1DX-QI) and provides insight into the development and growth of a successful type 1 diabetes quality improvement (QI) program. Since its inception 8 years ago, the collaborative has expanded to include centers across the United States with varying levels of QI experience, while simultaneously achieving many tangible improvements in type 1 diabetes care. These successes underscore the importance of learning health systems, data-sharing, benchmarking, and peer collaboration as drivers for continuous QI. Future efforts will include recruiting additional small- to medium-sized centers focused on adult care and underserved communities to further the goal of improving care and outcomes for all people living with type 1 diabetes.
RESUMO
Diabetes mellitus remains the leading cause of end-stage kidney disease worldwide. Inadequate glucose monitoring has been identified as one of the gaps in care for hemodialysis patients with diabetes, and lack of reliable methods to assess glycemia has contributed to uncertainty regarding the benefit of glycemic control in these individuals. Hemoglobin A1c, the standard metric to evaluate glycemic control, is inaccurate in patients with kidney failure, and does not capture the full range of glucose values for patients with diabetes. Recent advances in continuous glucose monitoring have established this technology as the new gold standard for glucose management in diabetes. Glucose fluctuations are uniquely challenging in patients dependent on intermittent hemodialysis, and lead to clinically significant glycemic variability. This review evaluates continuous glucose monitoring technology, its validity in the setting of kidney failure, and interpretation of glucose monitoring results for the nephrologist. Continuous glucose monitoring targets for patients on dialysis have yet to be established. While continuous glucose monitoring provides a more complete picture of the glycemic profile than hemoglobin A1c and can mitigate high-risk hypoglycemia and hyperglycemia in the context of the hemodialysis procedure itself, whether the technology can improve clinical outcomes merits further investigation.
RESUMO
We retrospectively evaluated outcomes of the Minimed Medtronic 670G system in an academic urban safety-net population of adults with type 1 diabetes, between September 2016 and January 2020. Among 32 patients prescribed the 670G, the majority were female (69%), white (69%), achieved advanced degrees (56%), were commercially insured (94%), and were experienced pump users (84%). Patients who initiated auto-mode demonstrated significant improvement in A1c after 1 year. However, 31% of patients never initiated auto-mode. Black and Hispanic patients comprised 50% of this group, despite similar insurance coverage, diabetes duration, educational level, and prior pump use. Hence, traditional barriers to technology use do not explain these racial/ethnic disparities. Of 22 patients who initiated auto-mode, 5 discontinued within 1 year. The most common reason for discontinuation was frustration with pump-sensor interactions. Future studies identifying barriers to and strategies for increasing use of advanced insulin delivery systems in underserved populations are needed.

Diabetes is an increasing public health problem, and insulin is the mainstay for treatment of type 1 diabetes. In type 2 diabetes treatment, insulin therapy is used after oral or other injectable agents become inadequate to achieve glycemic control. Despite the advances in insulin therapy, management of diabetes remains challenging. Numerous studies have reported low adherence and persistence to insulin therapy, which acts as a barrier to successful glycemic control and diabetes management. The aim of this targeted review article is to provide an overview of adherence and persistence to insulin therapy in people with diabetes and to discuss the impact of the emergence of a new connected ecosystem of increasingly sophisticated insulin pens, glucose monitoring systems, telemedicine, and mHealth on diabetes management. With the emergence of a connected diabetes ecosystem, we have entered an era of advanced personalized insulin delivery, which will have the potential to enhance diabetes self-management and clinical management. Early systems promise to unlock the potential to address missed or late bolus insulin delivery, which should help to address non-adherence and non-persistence. Over time, improvements in this ecosystem have the potential to combine insulin data with previously missing contextualized patient data, including meal, glucose, and activity data to support personalized clinical decisions and ultimately revolutionize insulin therapy.

OBJECTIVE: Rapid improvement in blood glucose (BG) after weight-loss surgery (WLS) can make postoperative glucose management challenging in patients with type 2 diabetes mellitus (T2DM). Our study examined the safety and efficacy of insulin management strategies during hospitalization and after discharge following WLS. METHODS: This single-center retrospective cohort study included 160 adult patients with type 2 diabetes mellitus undergoing WLS. Patients with glycated hemoglobin A1C (HbA1C) level <7% (53 mmol/mol) and not on antihyperglycemic medications or metformin monotherapy were excluded. BG and insulin dosing during hospitalization and at 2-week follow-up, and impact of preoperative HbA1C level were analyzed. RESULTS: Mean age was 46.3 years. Median preoperative HbA1C level was 8% (64 mmol/mol). Postoperatively, most patients received basal insulin plus sliding-scale insulin (SSI; 79/160, 49%) or SSI alone (77/160, 48%). The initial postoperative basal dose was 0.23 units/kg/day. The median basal insulin dose at discharge was 61% lower than preoperative dose. At 2-week follow-up, 34 of 44 patients (77%) had BG levels between 70-200 mg/dL and 1 of 44 (2.2%) had BG levels >200 mg/dL, with no hypoglycemia. Patients with HbA1C level >9% (75 mmol/mol) had higher BG on admission and during hospitalization, required higher insulin doses while hospitalized, and were more frequently discharged on insulin. CONCLUSION: SSI is effective in managing BG in some patients immediately after WLS. However, about half of the patients may require basal insulin at doses similar to those required by other inpatients. Preoperative hyperglycemia may affect inpatient insulin needs and BG. Low-dose basal insulin appears safe and effective upon discharge for select patients.

BACKGROUND: Limitations in access to specialty diabetes care exist. Endocrinology eConsult that integrates professional continuous glucose monitoring (CGM-enhanced eConsult) may improve healthcare delivery, but has yet to be evaluated. We implemented a pilot program for patients with type 2 diabetes (T2DM) managed by primary care clinical pharmacists using CGM-enhanced eConsult and evaluated the acceptability and clinical outcomes in comparison to routine in-person endocrinology consultation. METHODS: Seventy-four adult patients with established T2DM (age 18-65) were included. Twenty-nine were seen in-person by endocrinology and 45 were seen by pharmacists in primary care. Thirteen patients were referred for CGM-enhanced eConsult. Acceptability was assessed with pre/post clinician acceptability questionnaires and patient assessment of perceived burden. Clinical outcomes included time to first specialty appointment, baseline and 3-month follow-up HbA1c, and antihyperglycemic medication use. RESULTS: There were no differences in patient acceptability of the CGM-enhanced eConsult as compared to endocrinology referral or pharmacy care. At baseline, all patients referred for eConsult were prescribed insulin. Three-month glycemic outcomes were comparable, with HbA1c reduction 1% + 2% in endocrinology, 1.5% + 1.1% with CGM-enhanced eConsult, and 1.6% + 1.8% in clinical pharmacy (p = 0.19). Time to an initial diabetes visit with a pharmacist was significantly shorter than with endocrinology, 20 days (IQR 26) for pharmacy vs. 45 days (IQR 54) for endocrinology, (p = 0.0001). CONCLUSIONS: CGM-enhanced eConsult resulted in more timely access to endocrinology expertise, was acceptable to patients, and resulted in similar short-term glycemic outcomes compared to in-person consultation. Effectiveness of CGM-enhanced eConsults should be further explored.
RESUMO
CONTEXT: Diabetes mellitus is associated with increased COVID-19 morbidity and mortality, but there are few data focusing on outcomes in people with type 1 diabetes. OBJECTIVE: The objective of this study was to analyze characteristics of adults with type 1 diabetes for associations with COVID-19 hospitalization. DESIGN: An observational multisite cross-sectional study was performed. Diabetes care providers answered a 33-item questionnaire regarding demographics, symptoms, and diabetes- and COVID-19-related care and outcomes. Descriptive statistics were used to describe the study population, and multivariate logistic regression models were used to analyze the relationship between glycated hemoglobin (HbA1c), age, and comorbidities and hospitalization. SETTING: Cases were submitted from 52 US sites between March and August 2020. PATIENTS OR OTHER PARTICIPANTS: Adults over the age of 19 with type 1 diabetes and confirmed COVID-19 infection were included. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Hospitalization for COVID-19 infection. RESULTS: A total of 113 cases were analyzed. Fifty-eight patients were hospitalized, and 5 patients died. Patients who were hospitalized were more likely to be older, to identify as non-Hispanic Black, to use public insurance, or to have hypertension, and less likely to use continuous glucose monitoring or insulin pumps. Median HbA1c was 8.6% (70 mmol/mol) and was positively associated with hospitalization (odds ratio 1.42, 95% confidence interval 1.18-1.76), which persisted after adjustment for age, sex, race, and obesity. CONCLUSIONS: Baseline glycemic control and access to care are important modifiable risk factors which need to be addressed to optimize care of people with type 1 diabetes during the worldwide COVID-19 pandemic.

OBJECTIVE: To evaluate the use of preoperative vitamin D levels and postoperative vitamin D supplementation among endocrinologists for the prevention of post-thyroidectomy hypocalcaemia. METHODS: Endocrinologist members of the American Thyroid Association (ATA) were contacted via email to complete a 21-question survey, which included both questions about demographic information, and preventing and managing postoperative hypocalcaemia after thyroidectomy. Univariate and multivariate analysis was performed to determine the respondents' use of preoperative vitamin D levels, dose and duration of preoperative vitamin D repletion, decision to delay surgery for low vitamin D levels in the case of a benign or malignant disease, and routine prescription of postoperative calcium or vitamin D supplementation. RESULTS: 225 endocrinologists who were ATA members responded to the questionnaire. When compared to endocrinologists practicing in other countries, those that practice in the United States were 2.5 times more likely to check preoperative vitamin D levels (95% CI[1.404, 4.535], P = .002), significantly more likely to replete vitamin D deficient patients with high-dose vitamin D (ie ≥50K IU/week), 4.458 times more likely to prescribe prophylactic supplemental calcium (95% CI[2.446, 8.126]; P < .0001) and 3.48 more likely to prescribe supplemental vitamin D (95% CI [1.906, 6.355]; P < .0001). Endocrinologists who have been in practice for >10 years were also 1.915 times more likely to prescribe supplemental vitamin D (95% CI (1.080, 3.395); P = .0263). Physicians that treat >50 thyroidectomy cases/year were 2.083 more likely to recommend a vitamin D repletion duration of >1 month than those that treat ≤50 cases/year ([1.036, 4.190], P = .0395). Lastly, if the patient has low preoperative vitamin D levels, 47.05% of respondents chose to delay surgery in a benign disease, while only 11.61% of respondents would do so in a case of malignant disease. CONCLUSIONS: Approximately one-half of surveyed endocrinologists reported using preoperative vitamin D levels to assess a patient's risk for post-thyroidectomy hypocalcaemia. Endocrinologists practicing in the United States, compared to those practicing in other countries, were more likely to both test for preoperative vitamin D levels and to recommend prophylactic post-thyroidectomy calcium and vitamin D supplementation.

We present the case of a 27-year-old woman with inadequately controlled HNF1A maturity-onset diabetes of the young (MODY) who was successfully transitioned from sulfonylurea therapy to once-weekly monotherapy with dulaglutide, a glucagon-like peptide-1 receptor agonist (GLP-1 RA). More than a decade from diabetes diagnosis, she has maintained optimal glycemic control without hypoglycemia for >12 months while receiving GLP-1 RA therapy alone. This case illustrates the potential for successful use of GLP-1 RA monotherapy in patients with HNF1A MODY.
