Twenty years of pediatric diabetes surveillance: what do we know and why it matters

Variations in Management and Clinical Outcomes for Children With Diabetic Ketoacidosis in an Academic Pediatric Versus Community Emergency Department Setting

OBJECTIVES

Our objectives were to characterize variations from standardized, evidence-based guidelines in the management of pediatric patients with diabetic ketoacidosis (DKA) based on initial presentation to a tertiary pediatric emergency department (PED) versus a community emergency department (OSH) and compare clinical outcomes.

METHODS

We conducted a retrospective study on children 18 years and younger with DKA who presented to an OSH or PED over a 3-year period. Treatments monitored for variation included intravenous fluid management, insulin delivery, and sodium bicarbonate administrations. Clinical outcomes included time to anion gap correction and on insulin infusion, hypokalemia, hypoglycemia, rapid serum glucose decline, cerebral edema, mechanical ventilation, mortality, and time from initial presentation to hospital discharge.

RESULTS

Children with DKA who presented to an OSH (n = 250) were more acidotic (pH 7.11 vs. 7.13, P = 0.001) and had larger anion gaps (28.8 vs. 25.5, P < 0.001) compared with children presenting to the PED (n = 237). The OSH patients were more likely to receive larger fluid boluses (>20 cc/kg or >1000 ml, 43% vs. 4%, P < 0.001), sodium bicarbonate (5% vs. 0%, P < 0.001), and intravenous bolus insulin (28% vs. 0%, P < 0.001). The OSH group were less likely to be started on maintenance intravenous fluids (70% vs. 99%, P < 0.001) or receive potassium in maintenance intravenous fluids (14% vs. 42%, P < 0.001). The OSH group had longer anion gap correction times (754 vs. 541 mins, P < 0.001), insulin infusion times (1018 vs. 854 min, P = 0.003), and times to hospital discharge (3358 vs. 3045 mins, P < 0.001). Incidence of hypokalemia, hypoglycemia, rapid glucose decline, cerebral edema, and deaths were similar between the 2 groups.

CONCLUSIONS

Our study demonstrated significant variations in the initial management of pediatric DKA patients by OSH facilities that deviated from an evidence-based treatment pathway utilized by a PED. Statewide quality improvement initiatives could help improve the overall clinical care provided to pediatric DKA patients.

Reevaluating First-line Therapies in Youth-Onset Type 2 Diabetes

The prevalence of youth-onset type 2 diabetes is growing worldwide and current first-line treatment with metformin and intensive behavior and lifestyle changes are suboptimal in over 50% of youth within 2 years of diagnosis. This perspective article is a call to action for reevaluation of existing strategies and critical appraisal of metformin as first-line therapy in youth-onset type 2 diabetes. Increased attention should be given to novel therapeutics approved in youth, including glucagon-like 1 receptor agonists, sodium glucose cotransporter-2, and sociocultural interventions that will promote diabetes self-management.

Using electronic health records to enhance surveillance of diabetes in children, adolescents and young adults: a study protocol for the DiCAYA Network

INTRODUCTION

Traditional survey-based surveillance is costly, limited in its ability to distinguish diabetes types and time-consuming, resulting in reporting delays. The Diabetes in Children, Adolescents and Young Adults (DiCAYA) Network seeks to advance diabetes surveillance efforts in youth and young adults through the use of large-volume electronic health record (EHR) data. The network has two primary aims, namely: (1) to refine and validate EHR-based computable phenotype algorithms for accurate identification of type 1 and type 2 diabetes among youth and young adults and (2) to estimate the incidence and prevalence of type 1 and type 2 diabetes among youth and young adults and trends therein. The network aims to augment diabetes surveillance capacity in the USA and assess performance of EHR-based surveillance. This paper describes the DiCAYA Network and how these aims will be achieved.

METHODS AND ANALYSIS

The DiCAYA Network is spread across eight geographically diverse US-based centres and a coordinating centre. Three centres conduct diabetes surveillance in youth aged 0-17 years only (component A), three centres conduct surveillance in young adults aged 18-44 years only (component B) and two centres conduct surveillance in components A and B. The network will assess the validity of computable phenotype definitions to determine diabetes status and type based on sensitivity, specificity, positive predictive value and negative predictive value of the phenotypes against the gold standard of manually abstracted medical charts. Prevalence and incidence rates will be presented as unadjusted estimates and as race/ethnicity, sex and age-adjusted estimates using Poisson regression.

ETHICS AND DISSEMINATION

The DiCAYA Network is well positioned to advance diabetes surveillance methods. The network will disseminate EHR-based surveillance methodology that can be broadly adopted and will report diabetes prevalence and incidence for key demographic subgroups of youth and young adults in a large set of regions across the USA.

Sociodemographic factors associated with major depressive episodes and suicidal ideation among emerging adults with diabetes in the U.S

Background

Research focused on disparities related to mental health comorbidities, especially among emerging adults with diabetes, is limited. Identifying associated factors of disparities could inform policy decisions to make diabetes-related interdisciplinary care more accessible for vulnerable groups.

Method

Using data from the National Survey on Drug Use and Health (2015-2019), we examined disparities in presence of major depressive episode (MDE) and suicidal ideation among emerging adults with diabetes. Survey design-adjusted bivariate and multivariable logistic regression models were used for statistical analyses.

Results

The study included 1,125 emerging adults (18-25 years old), with a history of type 1 diabetes (T1D) or type 2 diabetes (T2D). After controlling for sociodemographic and health-related characteristics, we found lower odds of having past-year major MDE for non-Hispanic Black (AOR, 0.42, p=0.032) compared to their non-Hispanic White counterparts. Females were 3.02 times more likely to have past-year MDE than males (AOR, 3.02, p=0.004). The odds of having past-year MDE were 1.96 times higher among individuals who identified as LGB (lesbian, gay, bisexual) (AOR, 1.96, P=0.038). There were no statistically significant disparities in suicidal ideation related to race/ethnicity, sex, education, and family income. However, individuals who identified as LGB had significantly higher likelihood of suicidal ideation than their heterosexual counterparts (AOR, 2.47, P=0.004).

Conclusion

Significant disparities related to MDE and suicidal ideation exist based on race/ethnicity, gender, and sexual orientation. Integration of a mental health professional into the multidisciplinary diabetes care team is critical for effective management of comorbid mental health conditions in younger patients with diabetes.

Endocrine Health and Health Care Disparities in the Pediatric and Sexual and Gender Minority Populations: An Endocrine Society Scientific Statement

Endocrine care of pediatric and adult patients continues to be plagued by health and health care disparities that are perpetuated by the basic structures of our health systems and research modalities, as well as policies that impact access to care and social determinants of health. This scientific statement expands the Society's 2012 statement by focusing on endocrine disease disparities in the pediatric population and sexual and gender minority populations. These include pediatric and adult lesbian, gay, bisexual, transgender, queer, intersex, and asexual (LGBTQIA) persons. The writing group focused on highly prevalent conditions-growth disorders, puberty, metabolic bone disease, type 1 (T1D) and type 2 (T2D) diabetes mellitus, prediabetes, and obesity. Several important findings emerged. Compared with females and non-White children, non-Hispanic White males are more likely to come to medical attention for short stature. Racially and ethnically diverse populations and males are underrepresented in studies of pubertal development and attainment of peak bone mass, with current norms based on European populations. Like adults, racial and ethnic minority youth suffer a higher burden of disease from obesity, T1D and T2D, and have less access to diabetes treatment technologies and bariatric surgery. LGBTQIA youth and adults also face discrimination and multiple barriers to endocrine care due to pathologizing sexual orientation and gender identity, lack of culturally competent care providers, and policies. Multilevel interventions to address these disparities are required. Inclusion of racial, ethnic, and LGBTQIA populations in longitudinal life course studies is needed to assess growth, puberty, and attainment of peak bone mass. Growth and development charts may need to be adapted to non-European populations. In addition, extension of these studies will be required to understand the clinical and physiologic consequences of interventions to address abnormal development in these populations. Health policies should be recrafted to remove barriers in care for children with obesity and/or diabetes and for LGBTQIA children and adults to facilitate comprehensive access to care, therapeutics, and technological advances. Public health interventions encompassing collection of accurate demographic and social needs data, including the intersection of social determinants of health with health outcomes, and enactment of population health level interventions will be essential tools.

Effective assay technologies fit for large-scale population screening of type 1 diabetes

While worldwide prevention efforts for type 1 diabetes (T1D) are underway to abrogate or slow progression to diabetes, mass screening of islet autoantibodies (IAbs) in the general population is urgently needed. IAbs, the most reliable biomarkers, play an essential role in prediction and clinical diagnosis of T1D. Through laboratory proficiency programs and harmonization efforts, a radio-binding assay (RBA) has been well established as the current 'gold' standard assay for all four IAbs. However, in view of the need for large-scale screening in the non-diabetic population, RBA consistently faces two fundamental challenges, cost-efficiency and disease specificity. While all four IAbs are important for disease prediction, the RBA platform, with a separate IAb test format is laborious, inefficient and expensive. Furthermore, the majority of IAb positivity in screening, especially from individuals with single IAb were found to be low risk with low affinity. It is well documented from multiple clinical studies that IAbs with low affinity are low risk with less or no disease relevance. At present, two non-radioactive multiplex assays, a 3-assay ELISA combining three IAbs and a multiplex ECL assay combining all four IAbs, have been successfully used as the primary methods for general population screenings in Germany and the US, respectively. Recently, the TrialNet Pathway to Prevention study has been organizing an IAb workshop which aims to analyze the 5-year T1D predictive values of IAbs. A T1D-specific assay with high efficiency, low cost and requiring low volume of sample will definitely be necessary to benefit general population screening.

ISPAD Clinical Practice Consensus Guidelines 2022: Type 2 diabetes in children and adolescents

Since the 2018 ISPAD guidelines on this topic, follow-up of large cohorts from around the globe have continued informing the current incidence and prevalence of co-morbidities and complications in young adults with youth-onset type 2 diabetes (T2D). This chapter focuses on the risk factors, diagnosis and presentation of youth-onset T2D, the initial and subsequent management of youth-onset T2D, and management of co-morbidities and complications. We include key updates from the observational phase of the multi-center Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY) clinical trial, the SEARCH for Diabetes in Youth (SEARCH) study and new data from the Restoring Insulin Secretion (RISE) study, a head-to-head comparison of youth onset vs adult-onset T2D. We also include an expanded section on risk factors associated with T2D, algorithms and tables for treatment, management, and assessment of co-morbidities and complications, and sections on recently approved pharmacologic therapies for the treatment of youth-onset T2D, social determinants of health, and settings of care given COVID-19 pandemic.

Transitioning care in youth-onset type 1 and type 2 diabetes: a scoping review protocol using the socio-ecological model framework

INTRODUCTION

The transition from paediatric to adult diabetes care in youth-onset diabetes (type 1 diabetes mellitus, Y-T1DM and type 2 diabetes mellitus, Y-T2DM) is associated with worsening glycaemic control, missed clinical visits, decreased medication adherence and the emergence of cardiometabolic complications. The socio-ecological challenges that influence transitioning to adult diabetes care may be distinct between Y-T1DM and Y-T2DM. The goal of this scoping review is to map the state of the literature on transitioning care in Y-T2DM compared with Y-T1DM and to identify the main sources and types of evidence available. The objectives are : (1) to identify the factors within the socio-ecological framework (individual, relationship, community, societal) associated with transitioning to adult care in Y-T2DM compared with Y- T1DM, and (2) to identify knowledge gaps related to transitioning to adult care.

METHODS

The scoping review protocol and reporting will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for scoping reviews guidelines. A systematic search of scientific databases (PubMed, Embase, Cumulative Index to Nursing and Allied Health, Scopus and APA PsycNet will be undertaken for articles between 1 January 1990 and 30 September 2022. Study designs will include peer-reviewed experimental and quasi-experimental published studies without language or country-specific restrictions. We will exclude articles on other diabetes subtypes and will exclude non-peer reviewed articles such as opinion papers, anecdotal reports or supplementary commentaries.

ANALYSIS

References will be collated, sorted and extracted using Covidence. Factors associated with transition from paediatric to adult diabetes care in Y-T1DM and Y-T2DM will be identified using the socio-ecological framework and results will be presented in narrative format, tables, and summary graphs.

ETHICS AND DISSEMINATION

Ethical approval will not be applicable for this review.

Risk factors on testicular function in adolescents

PURPOSE

Adolescence represents an important window for gonadal development. The aim of this review is to carry out a critical excursus of the most recent literature on endogenous and exogenous risk factors related to testicular function, focusing the research on adolescence period.

METHODS

A comprehensive literature search within PubMed was performed to provide a summary of currently available evidence regarding the impact on adolescence of varicocele, cryptorchidism, cancer, diabetes, lifestyle factors, endocrine disruptors, obesity and sexually transmitted diseases. We focused on human studies that evaluated a possible impact of these factors on puberty timing and their effects on andrological health.

RESULTS

Evidence collected seems to suggest that andrological health in adolescence may be impaired by several factors, as varicocele, cryptorchidism, and childhood cancer. Despite an early diagnosis and treatment, many adolescents might still have symptoms and sign of a testicular dysfunction in their adult life and at the current time it is not possible to predict which of them will experience andrological problems. Lifestyle factors might have a role in these discrepancies. Most studies point out towards a correlation between obesity, insulin resistance, alcohol, smoking, use of illegal drugs and testicular function in pubertal boys. Also, endocrine disruptors and sexually transmitted diseases might contribute to impair reproductive health, but more studies in adolescents are needed.

CONCLUSION

According to currently available evidence, there is an emerging global adverse trend of high-risk and unhealthy behaviors in male adolescents. A significant proportion of young men with unsuspected and undiagnosed andrological disorders engage in behaviors that could impair testicular development and function, with an increased risk for later male infertility and/or hypogonadism during the adult life. Therefore, adolescence should be considered a key time for intervention and prevention of later andrological diseases.

Type 1 diabetes in diverse ancestries and the use of genetic risk scores

Over 75 genetic loci within and outside of the HLA region influence type 1 diabetes risk. Genetic risk scores (GRS), which facilitate the integration of complex genetic information, have been developed in type 1 diabetes and incorporated into models and algorithms for classification, prognosis, and prediction of disease and response to preventive and therapeutic interventions. However, the development and validation of GRS across different ancestries is still emerging, as is knowledge on type 1 diabetes genetics in populations of diverse genetic ancestries. In this Review, we provide a summary of the current evidence on the evolutionary genetic variation in type 1 diabetes and the racial and ethnic differences in type 1 diabetes epidemiology, clinical characteristics, and preclinical course. We also discuss the influence of genetics on type 1 diabetes with differences across ancestries and the development and validation of GRS in various populations.

Prevalence trends of type 1 and type 2 diabetes in children and adolescents in North Rhine-Westphalia, the most populous federal state in Germany, 2002-2020

AIMS

To estimate the prevalence and temporal trends of type 1 and type 2 diabetes mellitus in children and adolescents (type 1 diabetes: 0-19 years, type 2 diabetes: 10-19 years) in North Rhine-Westphalia (NRW), Germany, from 2002 to 2020.

METHODS

The NRW Diabetes Registry records new cases based on three data sources (median completeness of ascertainment 99% for type 1 diabetes, 94% for type 2 diabetes). We determined age- and/or sex-standardized prevalence estimates (95% confidence intervals) per 100,000 individuals. Differences in age and sex, as well as time trends, were examined by Poisson regression. Furthermore, joinpoint regression was used to evaluate changes in prevalence trends over time.

RESULTS

At the end of 2020, the estimated type 1 diabetes prevalence was 247.1 (240.3; 253.9) with an annual increase of 2.9% (2.7%; 3.1%). The type 2 diabetes prevalence was 12.7 (10.6; 14.9) and increased by 6.4% (5.6%; 7.3%) per year. The prevalence trends were not uniform over the total period and flattened considerably in recent years.

CONCLUSIONS

The prevalence of type 1 and type 2 diabetes has increased significantly but at a lower rate in recent years. Continued surveillance of the prevalence is essential for the planning of health care resources and prevention measures.

The Significance of Exposure to Pregestational Type 2 Diabetes in Utero on Fetal Renal Size and Subcutaneous Fat Thickness

Objectives. To determine the relationship between exposure to pregestational type 2 diabetes (T2D) and renal size and subcutaneous fat thickness in fetuses during routine obstetrical ultrasound. Methods. This was a case-control study (January 1, 2019 to December 31, 2019). Routine obstetrical ultrasounds performed between 18 and 22 weeks’ gestation at a tertiary-care fetal assessment unit were reviewed. “Cases” comprised ultrasounds of fetuses exposed to pregestational T2D in utero. The control group was assembled from ultrasounds of healthy controls. Postprocessing measurements of fetal renal size and abdominal wall thickness from stored images were performed by two independent observers, and findings were compared between groups. Results. There were 54 cases and 428 ultrasounds of healthy controls. The mean maternal age of cases was 32.1 years (SD 6.2) compared to 33.2 years (SD 5.3) for healthy controls, and the majority of ultrasounds were performed in multiparous patients (83%). At the 18 to 22 week ultrasound, there was a significant reduction in renal size amongst fetuses exposed to maternal T2D in utero compared to controls; among cases, the mean renal width was 8.0 mm (95% CI 7.8–8.1) compared to 11.4 mm (95% CI 10.6–12.7) in controls ( $p<0.0001$ ); the mean renal thickness among cases was 8.1 mm (95% CI 7.9–8.2) compared to 11.5 mm (95% CI 10.7–12.9) in controls ( $p=0.001$ ). There was no obvious difference in estimated fetal weight between groups, yet fetuses exposed to maternal T2D had increased subcutaneous abdominal wall fat thickness at this early gestational age ( $p=0.008$ ). Conclusions. Fetal renal size in cases exposed to pregestational T2D is significantly smaller compared to controls, and subcutaneous abdominal wall fat is significantly thicker. Given emerging evidence about the developmental origins of disease, further study is needed to correlate the association between fetal renal size and fat distribution in the fetus and the long-term risk of chronic renal disease and diabetes in these offspring.

Resilience and Diabetes Distress at 3 Months Following Diagnosis Predict A1C Trajectories in Youth With Type 1 Diabetes: An Argument for Early Intervention

OBJECTIVE

Youth and adolescents with type 1 diabetes (T1D) are at risk for poor health outcomes. Understanding if psychological factors shortly following diagnosis, such as diabetes distress and resilience, predict glycated hemoglobin (A1C) trajectories may help inform both optimal timing and content of psychosocial interventions for youth with T1D.

METHODS

Youth and adolescents (N = 34) with newly diagnosed T1D completed distress and resilience measures at baseline and 3 months following diagnosis. Using multilevel modeling, we predicted A1C trajectories up to 3 years following diagnosis.

RESULTS

We found that in separate models, higher 3-month diabetes distress and lower 3-month resilience predicted larger increases in A1C years 1-3 following diagnosis.

CONCLUSIONS

Our findings suggest that targeting resilience and diabetes distress within 3 months following diagnosis has implications for the yearly rate of A1C increase up to 3 years later.

2022 National Standards for Diabetes Self-Management Education and Support

PURPOSE

The National Standards for Diabetes Self-Management Education and Support (DSMES) provide guidance and evidence-based, quality practice for all DSMES services. Due to the dynamic nature of health care and diabetes research, the National Standards are reviewed and revised approximately every 5 years by key stakeholders and experts within the diabetes care and education community. For each revision, the Task Force is charged with reviewing the current National Standards for appropriateness, relevance, and scientific basis and making updates based on current evidence and expert consensus. In 2021, the group was tasked with reducing administrative burden related to DSMES implementation across diverse care settings.

CONCLUSION

The evidence supporting the 2022 National Standards clearly identifies the need to provide person-centered services that embrace cultural differences, social determinants of health, and the ever-increasing technological engagement platforms and systems. Payers are invited to review the National Standards as a tool to inform and modernize DSMES reimbursement requirements and to align with the evolving needs of people with diabetes (PWD) and physicians/other qualified health care professionals. The American Diabetes Association and the Association of Diabetes Care & Education Specialists strongly advocate for health equity to ensure all PWD have access to this critical service proven to improve outcomes both related to and beyond diabetes. The 2022 National Standards update is meant to be a universal document that is easy to understand and can be implemented by the entire health care community. DSMES teams in collaboration with primary care have been shown to be the most effective approach to overcome therapeutic inertia.

Glycaemic control and factors affecting it in type 1 diabetes in children: experience from a tertiary care centre in India

INTRODUCTION

Optimal glycaemic control is essential for the prevention of future micro- and macrovascular complications in type 1 diabetes (T1D). The type of insulin, the type of insulin delivery device, the caregiver's knowledge, the patient's age, duration of diabetes, and self-monitoring of blood glucose affect glycaemic control in type 1 diabetes. In the present study, we analysed glycaemic control and factors affecting it at a tertiary care centre in northern India.

MATERIAL AND METHODS

A retrospective review of records of patients registered between 2015 and 2018 was done. The data on demographic and disease-related factors were collected from the records. The different groups were compared with the t-test, one-way ANOVA, or Kruskal-Wallis test.

RESULTS

The mean age at the time of evaluation was 10.43 ±4.04 years (2-21 years), and the mean disease duration was 46.61 ±28.49 months (16-141 months). Most of the patients were prepubertal and using a basal-bolus regimen. The mean glycated haemoglobin (HbA1c ) was 7.96 ±1.46%, but only 24% had HbA1c below the International Society of Paediatric and Adolescent Diabetes (ISPAD) recommended desirable level of below 7%. Forty-six patients suffered one or more micro-macrovascular complications, and dyslipidaemia was the most common complication. Children with a longer duration of disease (8.39 ±1.42% vs. 7.59 ±1.65%), an episode of DKA (diabetes ketoacidosis) within a year of evaluation (9.19 ±2.54% vs. 7.93 ±1.39%), lower maternal (8.22 ±1.37% vs. 7.56 ±1.45%) and paternal education (8.26 ±1.67% vs. 7.78 ±1.30%), and hyperthyroid state (9.43 ±2.28% vs. 7.91 ±1.45%) had higher HbA1c.

CONCLUSIONS

Better diabetes education focusing on parents with lower education strata and children with longer disease duration and poor compliance can help improve glycaemic control in developing countries like India.
