ISPAD Clinical Practice Consensus Guidelines 2014. Assessment and monitoring of glycemic control in children and adolescents with diabetes

Ten Years of Improving Glycemic Control in Pediatric Diabetes Care: Data From the Norwegian Childhood Diabetes Registry

OBJECTIVE

To evaluate, from 2013 to 2022, how HbA1c, the incidence of acute complications, and use of diabetes technology changed at the national level in Norway and how glycemic control was associated with use of diabetes technology, carbohydrate counting, or participation in a quality improvement project.

RESEARCH DESIGN AND METHODS

This longitudinal observational study was based on 27,214 annual registrations of 6,775 children from the Norwegian Childhood Diabetes Registry from 2013 to 2022. Individuals aged >18 years, those with diabetes other than type 1, and those without HbA1c measurements were excluded. The outcome measure was HbA1c. The predictor variables in the adjusted linear mixed-effects model were 1) the use of diabetes technology, 2) the use of carbohydrate counting for meal bolusing, and 3) whether the patient's diabetes team participated in a quality improvement project.

RESULTS

Mean HbA1c decreased from 8.2% (2013) to 7.2% (2021), and the proportion of youth reaching an HbA1c <7.0% increased from 13% (2013) to 43% (2022). Insulin pump use increased from 65% (2013) to 91% (2022). Continuous glucose monitoring (CGM) use increased from 34% (first recorded in 2016) to 97% (2022). Insulin pump, CGM, and carbohydrate counting were associated with lower HbA1c and higher achievement of glycemic targets. Girls had a higher mean HbA1c than boys. Mean HbA1c levels were lower in clinics that participated in a quality improvement project for the following 4 years after the project.

CONCLUSIONS

Diabetes technology, carbohydrate counting, and systematic quality improvement in pediatric departments led to improved glycemic control.

Glycemic control and study of lipid and bone metabolism in type 1 diabetic children

Introduction. Type 1 diabetes mellitus is considered one of the most common chronic diseases of childhood. It is a high-risk factor for developing early cardiovascular disease and it also affects bone health. Objective. To describe demographic characteristics and biochemical parameters of a population of children with type 1 diabetes, evaluated in the pediatric diabetes unit of a tertiary Spanish hospital. Materials and methods. In this retrospective study, we determined metabolic, lipid, and bone parameters in 124 children with type 1 diabetes who were monitored in the pediatric diabetes unit of the Hospital Universitario Miguel Servet in Zaragoza (Spain) from May 2020 to July 2021. Results. Children with type 1 diabetes have worse metabolic control of the disease at puberty, but their lipid control is considered acceptable. We found an inverse correlation between bone formation markers and disease duration, as well as with metabolic control. Conclusion. Bone formation markers are inversely correlated with the percentage of glycated hemoglobin and diabetes evolution time. Patients’ lipid and bone profiles are more favorable when metabolic control of the disease is achieved.

Psychodiabetology: The Challenge of the Future?

The number of people suffering from diabetes, including type 1, is constantly increasing both in Poland and worldwide. Type 1 diabetes is a chronic disease characterized by uncertain prognosis and relapses, as well as permanent, irreversible, and progressive changes in health status. The ongoing disease results in dysfunction or disability, and the patient requires specialized supervision, care, and rehabilitation. However, the success of therapy does not depend solely on the perfection of treatment, but also on the patient's readiness to change their lifestyle and cooperate with the therapeutic team. The patient's constant alertness in making therapeutic decisions does not always lead to expected treatment results, and the risk of hypoglycemia associated with intensive insulin treatment depletes the patient's motivation for treatment, leading over time to the development of 'therapeutic burnout' and psychiatric disorders. This narrative review is an attempt to summarize the knowledge and possible future solutions in diabetes type 1 in Poland as well as highlight the importance of comprehensive care, including psychological care, which appears fundamental in a chronic disease such as type 1 diabetes. Therefore, the aim of the study was to present generational changes and psychosocial problems of patients with type 1 diabetes and to identify urgent challenges in diabetic care. Attention should be paid to the deteriorating mental condition of the young generations, who, in the course of diabetes, are exposed to additional psychological and psychiatric health problems. The next generation of patients will require more psychological care, which is why the challenge of the future is to create psychodiabetology centers.

Demographic, Clinical, Management, and Outcome Characteristics of 8,004 Young Children With Type 1 Diabetes

OBJECTIVE

To compare demographic, clinical, and therapeutic characteristics of children with type 1 diabetes age <6 years across three international registries: Diabetes Prospective Follow-Up Registry (DPV; Europe), T1D Exchange Quality Improvement Network (T1DX-QI; U.S.), and Australasian Diabetes Data Network (ADDN; Australasia).

RESEARCH DESIGN AND METHODS

An analysis was conducted comparing 2019-2021 prospective registry data from 8,004 children.

RESULTS

Mean ± SD ages at diabetes diagnosis were 3.2 ± 1.4 (DPV and ADDN) and 3.7 ± 1.8 years (T1DX-QI). Mean ± SD diabetes durations were 1.4 ± 1.3 (DPV), 1.4 ± 1.6 (T1DX-QI), and 1.5 ± 1.3 years (ADDN). BMI z scores were in the overweight range in 36.2% (DPV), 41.8% (T1DX-QI), and 50.0% (ADDN) of participants. Mean ± SD HbA1c varied among registries: DPV 7.3 ± 0.9% (56 ± 10 mmol/mol), T1DX-QI 8.0 ± 1.4% (64 ± 16 mmol/mol), and ADDN 7.7 ± 1.2% (61 ± 13 mmol/mol). Overall, 37.5% of children achieved the target HbA1c of <7.0% (53 mmol/mol): 43.6% in DPV, 25.5% in T1DX-QI, and 27.5% in ADDN. Use of diabetes technologies such as insulin pump (DPV 86.6%, T1DX 46.6%, and ADDN 39.2%) and continuous glucose monitoring (CGM; DPV 85.1%, T1DX-QI 57.6%, and ADDN 70.5%) varied among registries. Use of hybrid closed-loop (HCL) systems was uncommon (from 0.5% [ADDN] to 6.9% [DPV]).

CONCLUSIONS

Across three major registries, more than half of children age <6 years did not achieve the target HbA1c of <7.0% (53 mmol/mol). CGM was used by most participants, whereas insulin pump use varied across registries, and HCL system use was rare. The differences seen in glycemia and use of diabetes technologies among registries require further investigation to determine potential contributing factors and areas to target to improve the care of this vulnerable group.

Determinants of adherence to insulin and blood glucose monitoring among adolescents and young adults with type 1 diabetes in Qatar: a qualitative study

Background

Adherence to insulin and blood glucose monitoring (BGM) is insufficient in adolescents and young adults (AYAs) with type 1 diabetes (T1D) worldwide and in Qatar. Little is known about the factors related to being aware of suboptimal adherence and the beliefs related to suboptimal adherence in this group. This qualitative study investigated factors related to awareness of, and beliefs about suboptimal adherence, as well as the existence of specific action plans to combat suboptimal adherence using the I-Change model.

Methods

The target group was comprised of 20 Arab AYAs (17-24 years of age) with T1D living in Qatar. Participants were interviewed via semi-structured, face-to-face individual interviews, which were audio-recorded, transcribed verbatim, and analyzed using the Framework Method.

Results

Suboptimal adherence to insulin, and particularly to BGM, in AYAs with T1D was identified. Some AYAs reported to have little awareness about the consequences of their suboptimal adherence and how this can adversely affect optimal diabetes management. Participants also associated various disadvantages to adherence ( e.g., hypoglycemia, pain, among others) and reported low self-efficacy in being adherent ( e.g., when outside home, in a bad mood, among others). Additionally, goal setting and action-planning often appeared to be lacking. Factors facilitating adherence were receiving support from family and healthcare providers, being motivated, and high self-efficacy.

Conclusions

Interventions that increase awareness concerning the risks of suboptimal adherence of AYAs with T1D are needed, that increase motivation to adhere by stressing the advantages, creating support and increasing self-efficacy, and that address action planning and goal parameters.

Dual-basal-insulin regimen for the management of dawn phenomenon in children with type 1 diabetes: a retrospective cohort study

Background

Handling of the dawn phenomenon (DP) with multiple daily insulin injection (MDII) regimen is a real challenge.

Objective

We aimed to demonstrate the effectiveness of a dual-basal-insulin (a long-acting glargine and an intermediate-acting neutral protamine Hagedorn (NPH)) regimen for the management of DP in children with type 1 diabetes mellitus (T1DM). The primary efficacy outcome was to overcome morning hyperglycemia without causing hypoglycemia during the non-DP period of the night.

Design

Retrospective cohort study.

Method

Charts of 28 children with T1DM (12 female; 42.8%, mean age 13.7 ± 2.1 years) treated with MDII were retrospectively reviewed. The median duration of diabetes was 4.5 years (range 2-13.5 years). DP was diagnosed using a threshold difference of 20 mg/dL (0.1 mmol/L) between fasting capillary blood glucose at 3 a.m. and prebreakfast. NPH was administered at midnight in addition to daily bedtime (08.00-09.00 p.m.) glargine (dual-basal-insulin regimen). Midnight, 03:00 a.m., prebreakfast and postprandial capillary blood glucose readings, insulin-carbohydrate ratios, and basal-bolus insulin doses were recorded the day before the dual-basal-insulin regimen was started and the day after the titration of the insulin doses was complete. Body mass index standard deviation scores (BMI SDS) at the onset-3rd-12th month of treatment were noted.

Results

Before using dual basal insulin, prebreakfast capillary blood glucose levels were greater than those at midnight and at 03:00 a.m. (F = 64.985, p < 0.01). After titration of the dual-basal-insulin doses, there were significant improvements such that there were no statistically significant differences in the capillary blood glucose measurements at the three crucial time points (midnight, 03.00 a.m., and prebreakfast; F = 1.827, p = 0.172). No instances of hypoglycemia were reported, and the total daily insulin per kilogram of body weight did not change. The BMI SDS remained steady over the course of the 1-year follow-up.

Conclusion

In this retrospective cohort study, the dual-basal-insulin regimen, using a long-acting glargine and an intermediate-acting NPH, was effective in overcoming early morning hyperglycemia due to insulin resistance in the DP. However, the effectiveness of the dual-basal-insulin regimen needs to be verified by prospective controlled studies using continuous glucose monitoring metrics or frequent blood glucose monitoring.

The Turkish version of the problem areas in diabetes-parents of teens (P-PAID-T): Cross-cultural adaptation, reliability, and validity

OBJECTIVE

To examine the Turkish validity and reliability of the Problem Areas in Diabetes- Parents of Teens (P-PAID-T) scale and its psychometric properties for determining the parents' diabetes-related distress.

METHODS

The study included the parents of 200 adolescents with T1DM for at least a year. P-PAID-T and a demographic data form were used for data collection. Davis technique was used for the content validity of the scale. The scale's reliability was tested using test-retest, and its internal reliability was analyzed with Cronbach's alpha test. Exploratory Factor Analysis (EFA) was used to analyze the factor structure. Confirmatory Factor Analysis (CFA) was used to evaluate the fit of the scale.

RESULTS

69.5% (n = 139) of the participants were mothers. Compared to the fathers, the mothers' mean P-PAID-T score was significantly higher. Parents of sons, who used insulin injections for their children, and had a college degree or higher education level had higher P-PAID-T scores. The test-retest correlation coefficient of the scale was 0.977. The Cronbach α value of the scale was 0.901. The results of confirmatory factor analysis were x2/df = 2.931, GFI = 0.736, CFI = 0.711, NFI = 0.628, NNFI = 0.660, RMSEA = 0.141.

CONCLUSION

The Turkish version of P-PAID-T was a valid and reliable screening tool for measuring diabetes stress in parents of adolescents with T1DM.

PRACTICE IMPLICATIONS

Nurses could use the Turkish version of P-PAID-T to monitor parental diabetes distress and organize interventions; also Turkish P-PAID-T could facilitate research on diabetes distress for parents of adolescents with T1DM.

Household Food Insecurity and Cognition in Youth and Young Adults with Youth-Onset Diabetes

Objective

We evaluated the association of household food insecurity (FI) with cognition in youth and young adults with type 1 diabetes (T1D) or type 2 diabetes (T2D).

Design

In this cross-sectional study, age-adjusted scores for composite Fluid Cognition, and sub-domain scores for Receptive Language and Inhibitory Control and Attention, were modeled stratified by diabetes-type using linear regression, with FI in the past year as the predictor, controlling for covariates. Tests for processing speed, inhibitory control/attention, working memory, episodic memory, and cognitive flexibility were administered to measure composite Fluid Cognition score. The NIHT-CB Picture Vocabulary Test was used to assess Crystallized Cognition score and rapid identification of congruent versus noncongruent items were used to assess Inhibitory Control and Attention score.

Setting

The SEARCH for Diabetes in Youth study, representative of 5 U.S. states.

Participants

Included 1574 youth and young adults with T1D or T2D, mean age of 21 years, mean diabetes duration of 11 years, 51% non-Hispanic white, and 47% had higher HbA1c levels (>9% HbA1c).

Results

Approximately 18% of the 1,240 participants with T1D and 31% of the 334 with T2D experienced FI. The food-insecure group with T1D had a lower composite Fluid Cognition score (β= -2.5, 95% confidence interval (CI)= -4.8, -0.1) and a lower Crystallized Cognition score (β= -3.4, CI= -5.6, -1.3) than food-secure peers. Findings were attenuated to non-significance after adjustment for demographics. Among T2D participants, no associations were observed. In participants with T1D effect modification by glycemic levels were found in the association between FI and composite Fluid Cognition score but adjustment for socioeconomic characteristics attenuated the interaction (p=0.0531).

Conclusions

Food-insecure youth and young adults with T1D or T2D did not have different cognition compared to those who were food-secure after adjustment for confounders. Longitudinal research is needed to further understand relations amongst these factors.

Accuracy of Serological Screening for the Diagnosis of Celiac Disease in Type 1 Diabetes Children

Background and Objectives: Patients with type 1 diabetes (T1D) are considered at high-risk for developing celiac disease (CD). The purpose of our study was to determine the prevalence of CD among children who were followed in our unit for T1D using the latest ESPGHAN guidelines, and avoiding intestinal biopsies in some of the children. Materials and Methods: We performed a prospective monocentric study, which included 663 T1D children between June 2014 and June 2016. We considered CD according to serological (tissue transglutaminase (TGAs) and endomysium antibodies) results. Children were included either at the time of T1D diagnosis or during their follow up. We looked for clinical and biochemical signs of CD, and for T1D characteristics. Results: The children's ages ranged from 11 months to 18 years. CD was confirmed in 32 out of 663 patients with T1D, with a prevalence of 4.8%. CD was excluded in 619 children and remained uncertain for 12 children, who had positive TGAs without the required criteria. We found that 95% of T1D children express HLA-DQ2 and/or -DQ8, which was 2.4 times higher than in the general population. Conclusions: An intestinal biopsy could be avoided to confirm CD in the majority of T1D children. Silent forms of CD are frequent and screening is recommended for all patients. Importantly, repeated TGA assessment is required in HLA genetically predisposed T1D patients, while it is unnecessary in the 5% who are HLA-DQ2 and -DQ8 negative.

Comparison of regular with NPH insulin vs. premix insulin in children and adolescents with type 1 diabetes in a resources-limited setting: a retrospective data analysis

OBJECTIVES

Few studies addressed the efficacy of human insulin regimens (mostly premix insulin) used in many low-and-middle income countries on glycemic control of children and adolescents with diabetes. The aim of this study was to assess the efficacy of the premix insulin on the glycated hemoglobin (HbA_1c) in comparison to the regular with NPH insulin scheme.

METHODS

A retrospective study was carried out from January 2020 to September 2022 on patients with type 1 diabetes aged below 18 years followed in Burkina Life For A Child program. They were categorized into three groups, on regular with NPH insulin (Group A), on premix insulin (Group B) and on regular with premix insulin (Group C). Outcome was analyzed based on HbA_1c level.

RESULTS

Sixty-eight patients with a mean age of 15.38 ± 2.26 years and the sex ratio (M/W) 0.94 were studied. There were 14 in Group A, 20 in Group B, and 34 patients in Group C. The mean HbA_1c value in the corresponding insulin regimen was 12.8 ± 1.39%, 9.87 ± 2.18%, and 10.66 ± 2.1%, respectively. Glycemic control was better in Groups B and C than Group A (p<0.05) but there was no difference between groups B and C.

CONCLUSIONS

Our results indicate that the use of premix insulin gives a better glycemic control than NPH insulin. However, further prospective study of these insulin regimens with a strengthening education strategy and glycemic control by continuous glucose monitoring and HbA_1c is required to corroborate these preliminary findings.

Use of continuous subcutaneous insulin infusion versus multiple daily injections in emerging adults with type 1 diabetes is associated with better clinical engagement but not glycaemic control

BACKGROUND

Limited studies have compared outcomes between emerging adults with type 1 diabetes mellitus (T1D) attending a diabetes transition support programme using multiple daily injections (MDI) or continuous subcutaneous insulin infusion (CSII).

AIMS

To assess glycaemic control and service utilisation in emerging adults with T1D on MDI or CSII attending a young adult diabetes clinic (YAC).

METHODS

A retrospective cohort analysis was conducted from January 2013 to December 2015. Data collected included clinic visits per year, after-hours mobile telephone use, diabetic ketoacidosis (DKA) admissions and all HbA1c levels. Independent t-test was used to compare continuous variables whilst Pearson's Chi-squared test was used for categorical variables. Linear mixed effects models explored mean changes in HbA1c levels over time.

RESULTS

Over 3 years, 318 youth with T1D (176 MDI, 121 CSII, 21 switched from MDI to CSII) attended our YAC. Aggregated mean HbA1c levels remained similar between modalities (CSII 9.1% vs MDI 9.3%; P = 0.23); however, mean change in HbA1c at 3 years was significantly increased in CSII users at 0.55% (95% CI 0.15-0.95; P < 0.01) compared with no significant change in MDI users. Clinic visits per year were improved in CSII users (CSII 2.8 vs MDI 2.5; P = 0.02), while DKA admissions remained similar between MDI and CSII users (3.6 admissions per 100 patient-years).

CONCLUSION

In our YAC cohort, glycaemic control in CSII and MDI users was similar but well below recommended international glycaemic targets (HbA1c level < 7.0%). Despite increased clinical engagement occurring in CSII users, glycaemic deterioration was observed over the 3 years.

Managing Severe Hypoglycaemia in Patients with Diabetes: Current Challenges and Emerging Therapies

Hypoglycaemia is common in patients with diabetes mellitus and is a limiting factor for achieving adequate glycaemic control. In the vast majority of cases, hypoglycaemia develops due to the imbalance between food intake and insulin injections. As recurrent hypoglycaemia leads to significant morbidity and mortality, the recognition and immediate treatment of hypoglycaemia in diabetic patients is thus important. In the last 20 years, the introduction of improved insulin analogues, insulin pump therapy, continuous glucose monitoring (CGM), and sensor-augmented pump therapy have all made significant improvements in helping to reduce and prevent hypoglycaemia. In terms of treatment, the American Diabetes Association recommends oral glucose as the first-line treatment option for all conscious patients with hypoglycaemia. The second line of treatment (or first line in unconscious patients) is the use of glucagon. Novel formulations of glucagon include the nasal form, the Gvoke HypoPen which is a ready-to-deliver auto-injector packaged formulation and finally a glucagon analogue, Dasiglucagon. The Dasiglucagon formulation has recently been approved for the treatment of severe hypoglycaemia. It is a ready-to-use, similar to endogenous glucagon and its potency is also the same as native glucagon. It does not require reconstitution before injection and therefore ensures better compliance. Thus, significant improvements including development of newer insulin analogues, insulin pump therapy, continuous glucose monitoring (CGM), sensor-augmented pump therapy and novel formulations of glucagon have all contributed to reducing and preventing hypoglycaemia in diabetic individuals. However, considerable challenges remain as not all patients have access to diabetes technologies and to the newer glucagon formulations to help reduce and prevent hypoglycaemia.

Time to first optimal glycemic control and its predictors among type 1 diabetic children in Bahir Dar city public referral hospitals, North West Ethiopia: a retrospective follow up study

Background

Recognizing the level of glycemic control of a client is an important measure/tool to prevent acquiring complications and risk of death from diabetes. However, the other most important variable, which is the time that the patient stayed in that poor glycemic level before reaching optimal glycemic control, has not been studied so far. Therefore, this study aim to estimate time to first optimal glycemic control and identify predictors among type 1 diabetic children in Bahir Dar city public referral hospitals, Northwest, Ethiopia, 2021.

Methods

A Retrospective cohort study was conducted at Bahir Dar city public referral hospitals among a randomly selected sample of 385 patients with type 1 diabetes who were on follow up from January 1, 2016 to February30, 2021.Data were collected by using a data abstraction tool and then entered into Epi-data version 4.6 and exported into STATA 14.0 statistical software. Descriptive statistics, Kaplan Meier plots and median survival times, Log-rank test and Cox-proportional hazard regression were used for reporting the findings of this study. After performing Cox-proportional hazard regression, model goodness-of-fit and assumptions were checked. Finally, the association between independent variables and time to first optimal glycemic control in months was assessed using the multivariable Cox Proportional Hazard model and variables with a p-value < 0.05 were considered as statistically significant.

Results

Median survival time to first optimal glycemic control among type 1 diabetic clients was 8 months (95%CI: 6.9–8.9). The first optimal glycemic achievement rate was 8.2 (95%CI: 7.2–9.2) per 100 person/month observation. Factors that affect time to first optimal glycemic control were age > 10–14 years (AHR = 0.32;95%CI = 0.19–0.55), increased weight (AHR = 0.96;95%CI = 0.94–0.99), having primary care giver (AHR = 2.09;95%CI = 1.39–3.13), insulin dose (AHR = 1.05;95%CI = 1.03–1.08), duration of diabetes ≥4 years (AHR = 0.64;95%CI = 0.44–0.94), adherence to diabetic care (AHR = 9.72;95%CI = 6.09–15.51), carbohydrate counting (AHR = 2.43;95%CI = 1.12–5.26), and comorbidity (AHR = 0.72;95%CI = 0.53–0.98).

Conclusion

The median survival time to first optimal glycemic control in this study was long. Age, weight, primary care giver, insulin dose, duration of diabetes, adherence, and carbohydrate counting, including history of comorbidity were determinant factors. Giving attention for overweight and comorbid illness prevention, increasing either the dose or frequency of insulin during initial treatment; counseling parent (for both the mother and father) about adherence to diabetic care focusing on insulin drugs and how to audit their children’s diet as prescription helps to reduce the length of glycemic control.

Adolescents with type 1 diabetes can achieve glycemic targets on intensive insulin therapy without excessive weight gain

Introduction

The aim of this study was to compare glycemic control and body mass index standard deviation score (BMI‐SDS) before and after implementation of intensive insulin therapy using multiple daily injection (MDI) or continuous subcutaneous insulin infusion (CSII) in adolescents with type 1 diabetes (T1D) attending a large multidisciplinary paediatric diabetes clinic in Australia.

Methods

Prospective data were collected for cross‐sectional comparison of youth aged 10.0–17.9 years (n = 669) from routine follow‐up visits to the diabetes clinic in 2004, 2010, and 2016. Outcome measures included HbA1c; BMI‐SDS; and insulin regimen.

Results

BMI‐SDS remained stable between 2004 to 2016 in the 10–13 and 14–17 year age group (0.7 vs. 0.5, p = .12 and 0.7 vs. 0.7, p = .93, respectively). BMI‐SDS was not different across HbA1c groups; <53 mmol/mol (7.0%), 53 to <75 mmol/mol (<7.0 to <9.0%) and >75 mmol/mol (>9.0%) in 2004 (p = .873), 2010 (p = .10) or 2016 (p = .630). Mean HbA1c decreased from 2004 to 2016 in the 10–13 year (69 mmol/mol (8.4%) vs. 57 mmol/mol (7.4%), p = <.001) and 14–17 year group (72 mmol/mol (8.7%) vs. 63 mmol/mol (7.9%), p = <.001). Prior to the implementation of MDI and CSII in 2004 only 10% of 10–13 year olds and 8% of 14–17 year olds achieved the international target for glycemic control (HbA_1c 53 mmol/mol [<7.0%]). In 2016, this increased to 31% of 10–13 year olds and 21% of 14–17 year olds.

Conclusions

BMI‐SDS did not increase with the change to intensive insulin therapy despite a doubling in the number of adolescents achieving the recommended glycemic target of <7.0% (53 mmol/mol). HbA1c was not associated with weight gain.

Caries experience and gingival health in children and adolescents with type 1 diabetes mellitus-A cross-sectional study

AIM

To investigate the oral health of children and adolescents with type 1 diabetes (T1D) and its associations with diabetes-related and lifestyle factors.

DESIGN

Cross-sectional study at a large tertiary hospital pediatric diabetes clinic. Oral examination determined dental caries experience and gingival health. Secondary outcome measures included salivary characteristics, oral hygiene and dietary practices, and diabetes-related factors.

RESULTS

Eighty children and adolescents with T1D participated; mean (SD) age and HbA_1c were 13.4(2.6) years and 7.7(0.9)%, respectively. Forty-seven (59%) participants had one or more decayed, missing or filled teeth; 75 (94%) participants had gingivitis. Half (50%) reported ≥3 hypoglycemic episodes necessitating rapid-acting carbohydrate in the previous week. Sixty-two participants (78%) had normal saliva flow, however, 42 (52%) had reduced salivary buffering capacity. Glycemic control (HbA_1c ) was not associated with caries experience, gingival health or salivary characteristics. Increased frequency of tooth brushing (OR, 0.11; 95%CI 0.01-0.97, p = 0.05) and interdental flossing (OR, 0.31; 95%CI 0.12-0.81, p = 0.02) were associated with lower caries experience. Interdental flossing (OR, 0.31; 95% CI 0.12-0.80, p = 0.02) and good oral hygiene (OR, 0.06; 95% CI 0.01-0.22, p < 0.001) were associated with less gingivitis.

CONCLUSION

Poor oral health is common in children with T1D, regardless of HbA1c. Given potential implications for short- and long-term systemic health, this study demonstrates the need for targeted strategies to improve oral health in children with T1D.

Inequalities in Glycemic Control in Youth with Type 1 Diabetes Over Time: Intersectionality Between Socioeconomic Position and Race and Ethnicity

BACKGROUND

Racial/ethnic health inequities have been well-documented among youth and young adults with type 1 diabetes (T1D), yet little is known about how socioeconomic position (SEP) intersects with the risk marker of race/ethnicity to predict inequities in longitudinal glycemic control.

PURPOSE

To identify patterns of SEP, race/ethnicity, and clinical characteristics that differentiate hemoglobin A1c (HbA1c) trajectories among youth and young adults after T1D diagnosis.

METHODS

The SEARCH for Diabetes in Youth cohort includes youth with diabetes diagnosed from 2002 to 2006 and 2008 who were followed through 2015. We analyzed data from 1,313 youth and young adults with T1D with ≥3 HbA1c measures. Classification tree analysis identified patterns of baseline demographic, SEP, and clinical characteristic that best predicted HbA1c trajectories over an average of 8.3 years using group-based trajectory modeling.

RESULTS

Two HbA1c trajectories were identified: Trajectory 1 (77%) with lower baseline HbA1c and mild increases (from mean 7.4% to 8.4%) and Trajectory 2 (23%) with higher baseline HbA1c and major increases (from 8.5% to 11.2%). Race/ethnicity intersected with different SEP characteristics among non-Hispanic white (NHW) than in non-whites. Public health insurance predicted high-risk Trajectory 2 membership in non-whites, whereas parental education, household structure, diagnosis age and glucose checking frequency predicted membership for NHW youth and young adults. Two characteristics, race/ethnicity and parental education alone identified 80% of the Trajectory 2 members.

CONCLUSIONS

Race/ethnicity intersects with multiple SEP and clinical characteristics among youth and young adults with T1D, which is associated with particularly high risk of poor long-term glycemic control.

Use of intermittently scanned continuous glucose monitoring in young people with high-risk type 1 diabetes-Extension phase outcomes following a 6-month randomized control trial

AIMS

To describe the impact of a 12-month intervention using intermittently scanned continuous glucose monitoring (isCGM) on glycaemic control and glucose test frequency in adolescents and young adults with type 1 diabetes (T1D) and high-risk glycaemic control (HbA_1c ≥75 mmol/mol [≥9.0%]).

METHODS

In total, 64 young people (aged 13-20 years, 16.6 ± 2.1 years; 48% female; 41% Māori or Pacific ethnicity; mean diabetes duration 7.5 ± 3.8 years) with T1D were enrolled in a 6-month, randomized, parallel-group study comparing glycaemic outcomes from the isCGM intervention (n = 33) to self monitoring blood glucose (SMBG) controls (n = 31). In this 6-month extension phase, both groups received isCGM; HbA_1c , glucose time-in-range (TIR), and combined glucose test frequency were assessed at 9 and 12 months.

RESULTS

At 12 months, the mean difference in HbA_1c from baseline was -4 mmol/mol [-0.4%] (95% confidence interval, CI: -8, 1 mmol/mol [-0.8, 0.1%]; p = 0.14) in the isCGM intervention group, and -7 mmol/mol [-0.7%] (95% CI: -16, 1 mmol/mol [-1.5, 0.1%]; p = 0.08) in the SMBG control group. No participants achieved ≥70% glucose TIR (3.9-10.0 mmol/L). The isCGM intervention group mean rate of daily glucose testing was highest at 9 months, 2.4 times baseline rates (p < 0.001), then returned to baseline by 12 months (incidence rate ratio = 1.4; 95% CI: 0.9, 2.1; p = 0.091).

CONCLUSIONS

The use of isCGM in young people with high-risk T1D resulted in transient improvements in HbA_1c and glucose monitoring over a 9-month time frame; however, benefits were not sustained to 12 months.

Characterising common challenges faced by parental caregivers of children with type 1 diabetes mellitus in mainland China: a qualitative study

OBJECTIVES

The mental state of parental caregivers affects outcomes in children with type 1 diabetes mellitus (T1DM). This study aimed to qualitatively examine perception of common challenges among parental caregivers of children with T1DM.

SETTING

Semistructured interviews 45-60 min long were conducted with parental caregivers of children with T1DM. Interview recordings were transcribed and coded in NVivo V.11.0 to observe emergent themes.

PARTICIPANTS

Eligible T1DM caregiving parents (parent(s) and/or legal guardian(s)) were identified from caregivers attending visits with children hospitalised or assessed in the Pediatric Neuroendocrinology Department of Shengjing Hospital, China Medical University in Shenyang from January 2018 to June 2019.

PRIMARY AND SECONDARY OUTCOME MEASURES

Not applicable.

RESULTS

A total of 20 T1DM caregiving parents were interviewed, aged 30-53 years, including 7 fathers and 13 mothers, with their children whose mean age was 10.6±2.45 years. Content analysis revealed 5 major themes with 13 subthemes, including persistent psychological stress (catastrophic emotions, emotional distress and altered self-efficacy), family function change (altered family life patterns and changes in parental role/function), challenges in daily management (technical challenges, emotional regulation, parent-child conflict and transition of care autonomy from parent to child), financial burden (cost burden of treatment and altered family economics), and lack of social support (social activity limitations and insufficient support system).

CONCLUSIONS

The period of emotional disturbance during initial diagnosis, psychological stresses of long-term caregiving, and conflict emerging from transition from parental to child responsibility all can cause psychological response detrimental to parental caregivers and children with T1DM. This work provides compelling evidence for the role of assessment and intervention in parental caregivers' psychological and emotional well-being in diabetes care, as well as for the necessity of improved social and school support for children with T1DM in China.

Serum iron is negatively correlated with the HbA1c level in children and adolescents with type 1 diabetes mellitus

Although mainly affected by the blood glucose levels, the level of HbA1c could be influenced by other important factors, such as an iron deficiency, which is commonly found in children with type 1 diabetes mellitus (T1DM). However, a clinical judgment could not be established, as previous studies still reported conflicting results and lack of data regarding Indonesia. We aimed to evaluate the correlation between the serum iron and HbA1c levels in children with T1DM. This single-center cross-sectional study was conducted from February to October 2020 at Sanglah Hospital, Bali, Indonesia. Patients aged 1–18 yr were included in this study. The HbA1c and serum iron levels were evaluated in the blood samples. Spearman and partial correlation analyses were used to analyze the correlations between variables. The statistical significance was set at P < 0.05. Thirty-three subjects were analyzed, with a mean age of 11.24 ± 3.76 yr. Low serum iron and poor glycemic index were found in 54.5% and 69.7% of the subjects, respectively. Spearman correlation analysis revealed a low negative correlation between the serum iron and HbA1c levels (Spearman’s rho = –0.376, P = 0.031). A partial correlation showed a moderate negative correlation (r = –0.473, P = 0.013) after adjusting for confounding variables. This study found a moderate negative correlation between the serum iron and HbA1c level in children and adolescents with T1DM.

Depression and anxiety in adolescents with type 1 diabetes and their parents

BACKGROUND

Longitudinal studies including parental distress when examining adverse health outcomes in adolescents with type 1 diabetes are lacking. This study examined whether parental depression and anxiety predict adolescent emotional distress and glycated hemoglobin A_1c (HbA_1c) 1 year later and whether a relation between parental distress and HbA_1c is mediated by the level of parental involvement in diabetes care and by treatment behaviors.

METHODS

Longitudinal path modeling was applied to data from 154 adolescents and parents from diabetes centers participating in the Longitudinal study of Emotional problems in Adolescents with type 1 diabetes and their Parents/caregivers (Diabetes LEAP). At baseline and 1-year follow-up, participants completed measures of depression and anxiety. HbA_1c was extracted from medical charts. Responsibility and treatment behavior questionnaires were completed by adolescents at baseline.

RESULTS

Baseline parental depressive and anxiety symptoms were not associated with 1-year adolescent depressive symptoms, anxiety symptoms, and HbA_1c. Responsibility division and treatment behaviors did not mediate associations between parental emotional distress and 1-year HbA_1c.

CONCLUSIONS

Parental depressive and anxiety symptoms did not predict adolescent health outcomes 1 year later. Future studies may determine whether the link is present in case of mood/anxiety disorders or severe diabetes-specific distress, or whether adolescents are resilient in the face of parental distress.

IMPACT

Adolescents with T1D are a vulnerable group in terms of psychological and health outcomes. Whether parental emotional distress (i.e., depressive and anxiety symptoms) is prospectively associated with adolescent emotional distress and/or HbA_1c has been understudied. Our results show that parental distress was not related to adolescent distress or HbA_1c 1 year later. Responsibility division and treatment behaviors did not mediate associations between parental emotional distress and 1-year HbA_1c. Future studies could determine whether these links are present in case of mood/anxiety disorders or severe diabetes-specific distress, or whether adolescents are resilient in the face of parental distress.

Relation of Health-Related Quality of Life with Glycemic Control and Use of Diabetes Technology in Children and Adolescents with Type 1 Diabetes: Results from a National Population Based Study

OBJECTIVE

The primary aim was to analyse the association between diabetes-specific health-related quality of life (HRQOL) and HbA1c in children and adolescents with type 1 diabetes. The secondary aims were to evaluate the associations between diabetes-specific HRQOL and age, sex, diabetes duration, and the use of diabetes technology in diabetes treatment. Research Design and Methods. Children with type 1 diabetes (10-17 years, N = 1,019) and parents (children <10 years, N = 371; 10-17 years, N = 1,070) completed the DISABKIDS diabetes-specific questionnaire (DDM-10) as part of the 2017 data collection for the Norwegian Childhood Diabetes Registry. The DDM-10 consists of two subscales-'impact' and 'treatment'-with six and four items, respectively. In the linear regression models, the items and subscales were outcome variables, while HbA1c, age, sex, diabetes duration, insulin pump use, and continuous glucose monitoring (CGM) system use were predictor variables.

RESULTS

Lower HbA1c measurements and male sex were associated with higher HRQOL scores on both DDM-10 scales in the age group 10-17 years, but not in children under 10 years. Parents gave lower HRQOL scores than children in the 10-17 age group. Insulin pump and CGM use were not significantly associated with HRQOL on the impact and treatment scale.

CONCLUSIONS

Low HbA1c and male sex are significantly associated with high HRQOL in children aged 10-17 with type 1 diabetes, but the use of diabetes technology is not positively associated with HRQOL. Differences in child- and parent-reported scores imply that parents might both over- and underestimate their child's HRQOL.

Bone Density, Geometry, and Mass by Peripheral Quantitative Computed Tomography and Bone Turnover Markers in Children with Diabetes Mellitus Type 1

BACKGROUND

The type 1 diabetes mellitus (T1DM) is a chronic systemic autoimmune-mediated disease characterised by the insulin deficiency and hyperglycaemia. Its deleterious effect on bones concerns not only bone mass, density, and fracture risk but also may involve the linear growth of long bones. Studies on the lower leg in children with T1DM by pQCT have generated conflicting results, and most of the studies published so far focused only on a selected features of the bone. An additional information about growth, modelling, and remodelling processes can be gathered by the bone turnover marker measurement. The objective of the study was to evaluate bone mineral density, mass, and geometry using peripheral quantitative computed tomography as well as bone turnover markers in the patients with type 1 diabetes mellitus. Material and Methods. Bone mineral density, mass, and geometry on the lower leg using peripheral quantitative computed tomography and serum osteocalcin (OC) and carboxyterminal cross-linked telopeptide of type 1 collagen (CTx) were measured in 35 adolescents with T1DM (15 girls) aged 12.3-17.9 yrs. The results were compared to age- and sex-adjusted reference values for healthy controls.

RESULTS

Both sexes reveal lower than zero Z-scores for lower leg 66% total cortical bone cross-sectional area to muscle cross-sectional area ratio (-0.97 ± 1.02, p = 0.002517 and -0.98 ± 1.40, p = 0.007050, respectively) while tibia 4% trabecular bone density Z-score was lowered in boys (-0.67 ± 1.20, p = 0.02259). In boys in Tanner stage 5 bone mass and dimensions were diminished in comparison to Tanner stages 3 and 4, while in girls, such a phenomenon was not observed. Similarly, bone formation and resorption were decreased in boys but not in girls. Consistently, bone turnover markers correlated positively with bone size, dimensions, and strength in boys only.

CONCLUSIONS

T1DM patients revealed a decreased ratio of cortical bone area/muscle area, reflecting disturbed adaptation of the cortical shaft to the muscle force. When analyzing bone mass and dimensions, boys in Tanner stage 5 diverged from "less-mature" individuals, which may suggest that bone development in these individuals was impaired, affecting all three: mass, size, and strength. Noted in boys, suppressed bone metabolism may result in impairment of bone strength because of inadequate repair of microdamage and accumulation of microfractures.

Deterioration in glycemic control on schooldays among children and adolescents with type 1 diabetes: A continuous glucose monitoring-based study

BACKGROUND

To investigate the effect of school life by comparing the glycemic control between holidays and schooldays in children and adolescents with type 1 diabetes (T1D).

METHODS

This observational study enrolled school-aged students with T1D (aged 6-19) from September 2019 to July 2021. Continuous glucose monitoring (CGM) records were processed and divided into holidays and schooldays. Other information was collected via questionnaires. We compared the results using paired T-test, Wilcoxon paired test and logistic regression analysis.

RESULTS

78 paticipants were included (40 boys, mean age 9.95 years). A total of 142,945 h of CGM data were analyzed. Overall, TIR (3.9-7.8 mmol/L) during holidays was better than schooldays [56.97 (SD 15.03) vs. 55.87 (15.06), %, p = 0.039]. On nocturnal (0-6 am) glycemic fluctuation, TIR was longer in children aged 6-10 [60.54 (17.40) vs. 56.98 (SD 16.32), %, p = 0.012] during holiday and TAR (7.8 mmol/L) was shorter [31.54 (17.54) vs. 35.54 (16.95), %, p = 0.013], compared with schooldays. In adolescents aged 10-19 years, TAR was also significantly shorter during holidays. Stratified analysis showed that girls, patients with longer duration, and insulin pump users had more pronounced worsening of nighttime glycemia on schooldays. Logistic regression analysis showed that girls had higher risk of worse nocturnal glycemic control [3.26, 95% CI: (1.17, 9.72), p = 0.027] and nocturnal hyperglycemia [OR = 2.95, 95% CI: (1.08, 8.56), p = 0.039], compared to boys.

CONCLUSIONS

Children and adolescents with T1D were found to have worse glycemic control in nighttime during schooldays.

Impact of OMNIPOD® on the quality of life of adolescents with type 1 diabetes

INTRODUCTION

Several pediatric studies have demonstrated that therapy using a conventional insulin pump improves glycemic control and quality of life. At the beginning of this study, a new tubeless insulin pump, Omnipod®, had recently been marketed in France.

OBJECTIVES

Analyze the response of adolescents treated with multiple injections to the proposal to use this new medical device and compare both the quality of life and the glycemic control of adolescents according to their choice.

MATERIAL AND METHODS

This was a prospective, observational study of adolescents aged 10-17 years who had type 1 diabetes for more than 1 year, all treated with multi-injection insulin delivery according to a basal-bolus regimen. They were separated into three groups: group A choosing to use the Omnipod® system, group B taking the time to think before making a decision, and group C choosing to keep their multi-injection therapy. The three groups were compared according to their quality of life with validated tools and glycemic control.

RESULTS

Groups were formed with 30 (25%) patients in group A, 55 patients (45%) in group B, and 36 patients (30%) in group C. As to the WHO Well-Being Index, no significant difference appeared in the study for the patients in the three groups. An increased treatment satisfaction score was found, evolving from 3.79 ± 0.68 to 4.36 ± 0.56, p = 0.002 (group A) and from 3.87 ± 0.7 to 4.16 ± 0.7, p = 0.032 (group B), with no significant change for group C (from 4.39 ± 0.6 to 4.31 ± 0.62, p = 0.582). The wish to change treatment score improved for group A (from 4.14 ± 0.88 to 1.68 ± 0.9; p < 0.001) and group B (from 3.51 ± 1.05 to 1.84 ± 1; p < 0.001), with no significant change for group C (from 1.81 ± 0 0.98 to 1.61 ± 0.8; p = 0.432). There was no significant difference regarding HbA1c rates in the three groups.

CONCLUSION

There was no significant difference in quality-of-life scores between adolescents who chose to switch from multiple injection to the tubeless patch pump and those who retained multi-injection treatment, but increased satisfaction was observed in the former group.

T1DMicro: A Clinical Risk Calculator for Type 1 Diabetes Related Microvascular Complications

Development of complications in type 1 diabetes patients can be reduced by modifying risk factors. We used a cross-sectional cohort of 1646 patients diagnosed with type 1 diabetes (T1D) to develop a clinical risk score for diabetic peripheral neuropathy (DPN), autonomic neuropathy (AN), retinopathy (DR), and nephropathy (DN). Of these patients, 199 (12.1%) had DPN, 63 (3.8%) had AN, 244 (14.9%) had DR, and 88 (5.4%) had DN. We selected five variables to include in each of the four microvascular complications risk models: age, age of T1D diagnosis, duration of T1D, and average systolic blood pressure and HbA1C over the last three clinic visits. These variables were selected for their strong evidence of association with diabetic complications in the literature and because they are modifiable risk factors. We found the optimism-corrected R2 and Harrell’s C statistic were 0.39 and 0.87 for DPN, 0.24 and 0.86 for AN, 0.49 and 0.91 for DR, and 0.22 and 0.83 for DN, respectively. This tool was built to help inform patients of their current risk of microvascular complications and to motivate patients to control their HbA1c and systolic blood pressure in order to reduce their risk of these complications.

Does Current Diabetes Technology Improve Metabolic Control? A Cross-Sectional Study on the Use of Insulin Pumps and Continuous Glucose Monitoring Devices in a Nationwide Pediatric Population

OBJECTIVE

To examine the use of multiple daily injections (MDI), insulin pumps, self-measured blood glucose (SMBG), and continuous glucose monitoring (CGM) systems, and their association with glycated hemoglobin (HbA1c), diabetic ketoacidosis (DKA), and severe hypoglycemia.

METHODS

In a pediatric population-based nationwide cross-sectional study, we analyzed data from 2623 participants up to 18 years of age with type 1 diabetes, using 2017 annual data from the Norwegian Childhood Diabetes Registry. HbA1c was adjusted for age, gender, and diabetes duration. Using a linear mixed-effects model, we assessed HbA1c and the incidence of DKA and severe hypoglycemia according to the use of MDI, insulin pumps, SMBG, and CGM.

RESULTS

We observed that 74.7% of participants were using an insulin pump and 52.6% were using a CGM system. Mean HbA1c was 7.8% (62 mmol/mol). The HbA1c of pump users was 0.14 percentage points (pp) higher than that of MDI users. Fewer pump users than MDI users achieved an HbA1c of < 7.5% (38.3 vs. 41.6%). CGM users had a 0.18 pp lower HbA1c than SMBG users, with 40.5 and 38.0%, respectively, achieving an HbA1c of < 7.5%. The incidence of severe hypoglycemia or hospitalization due to DKA was not different in pump and CGM users compared with nonusers. Compared with other insulin pumps, patch pump use was associated with a significantly lower odds ratio for DKA.

CONCLUSIONS

Despite the broad use of diabetes technology, as many as 61% of our pediatric cohort did not reach the HbA1c target recommended by the International Society for Pediatric and Adolescent Diabetes (ISPAD). Lower HbA1c was associated with CGM use but not with insulin pump use. Acute complications were not less frequent in the groups using insulin pumps or CGM compared with those using MDI and SMBG. Further research is required to explore the lower incidence of DKA among patch pump users.

Newest Diabetes-Related Technologies for Pediatric Type 1 Diabetes and Its Impact on Routine Care: a Narrative Synthesis of the Literature

Purpose of Review

This review aims to address the actual state of the most advanced diabetes devices, as follows: continuous subcutaneous insulin infusions (CSII), continuous glucose monitoring systems (CGM), hybrid-closed loop (HCL) systems, and “Do-it-yourself” Artificial Pancreas Systems (DIYAPS) in children, adolescents, and young adults. This review has also the objective to assess the use of telemedicine for diabetes care across three different areas: education, social media, and daily care.

Recent Findings

Recent advances in diabetes technology after integration of CSII with CGM have increased the popularity of this treatment modality in pediatric age and shifted the standard diabetes management in many countries. We found an impressive transition from the use of CSII and/or CGM only to integrative devices with automated delivery systems. Although much has changed over the past 5 years, including a pandemic period that precipitated a broader use of telemedicine in diabetes care, some advances in technology may still be an additional burden of care for providers, patients, and caregivers. The extent of a higher rate of “auto-mode” use in diabetes devices while using the HCL/DIYAPS is essential to reduce the burden of diabetes treatment.

Summary

More studies including higher-risk populations are needed, and efforts should be taken to ensure proper access to cost-effective advanced technology on diabetes care.

A decade of improved glycemic control in young children with type 1 diabetes: A population-based cohort study

BACKGROUND

Early-onset type 1 diabetes (T1D) is associated with high risk of early cardiovascular complications and premature death. The strongest modifiable risk factor is HbA1c. Other modifiable factors, such as overweight, also increase the risk of complications. During the last decade, the introduction of continuous glucose monitoring (CGM) has offered new options in the treatment of T1D.

OBJECTIVE

To compare treatment outcomes in children younger than 7 years with T1D in Sweden in two separate cohorts: one in 2008 and one in 2018.

METHODS

All children in the national pediatric diabetes registry (SWEDIABKIDS) younger than 7 years with T1D were included. Data from 2008 and 2018 were analyzed.

RESULTS

Data were available on 666 children (45% girls) in 2008 and 779 children (45% girls) in 2018. Mean age was 5.6 (1.4) versus 5.5 (1.4) years and mean diabetes duration 2.3 (1.4) versus 2.2 (1.4) years. The use of CGM increased from 0% to 98% and the use of an insulin pump from 40% in 2008 to 82% (p < 0.01)in 2018.Mean HbA1c was 58 mmol/mol (7.4%) in 2008 and 50 mmol/mol (6.7%) in 2018 (p < 0.01). The frequency of overweight and obesity was the same in 2008 and 2018(26% vs. 29%).

CONCLUSION

During this decade, usage of CGM and insulin pump increased and HbA1c decreased. However, HbA1c remained higher than the physiological level and thus continued to represent a cardiovascular risk, especially in combination with overweight or obesity. The frequency of overweight and obesity remained unchanged.

Dental Treatment Effect on Blood Glucose Level Fluctuation in Type 1 Unbalanced Diabetic Children

Diabetic patients struggle to maintain their blood glucose near normal levels to avoid the occurrence of hypo- or hyperglycemia discomfort. Dental practitioners must foresee such complications as they can also take place during dental treatment.

AIM AND OBJECTIVE

This study aims to evaluate the impact of the type and duration of dental treatment on the blood glucose level (BGL) fluctuation in type 1 unbalanced diabetic children [hemoglobin A1c (HbA1c) >7].

MATERIAL AND METHODS

A cross-sectional approach was conducted on 83 type 1 unbalanced diabetic children (HbA1c) > 7%, aged between 7 years and 12 years, divided into 40 females and 43 males in the Department of Pediatric Dentistry at the Lebanese University in Beirut. For dental treatments, diabetic children were scheduled for morning sessions 60-90 minutes after breakfast intake and a habitual insulin shot. Only patients with a BGL between 70 mg/dL and 300 mg/dL underwent dental treatments. The type, the duration of the dental session, and the BGL at the baseline (T0), and at the end of the session (T1) were recorded. The dental acts were classified into simple (without local anesthesia) and unpleasant with a solution of 2% lignocaine with 1:200,000 epinephrine. Statistical analyses were performed.

RESULTS

Fifty of 83 showed a decrease in their BGLs after dental treatments, 20 an increase, and 13 no change. For both genders, in simple acts, a statistical significance was noted (p = 0.0002) for the female and (p = 0.0014) for the males.

CONCLUSION

Treatment unbalanced diabetic children can be safely done by taking some precautions and measures to avoid a hypo- or hyperglycemia episode.

Psychosocial functioning and health related quality of life in children, adolescents and young adults with type 1 diabetes mellitus in Congo

OBJECTIVES

To describe the psychosocial functioning and assess the quality of life of children, adolescents and young adults with T1DM; and to identify the risk factors associated with the psychosocial experience and quality of life of these patients.

MATERIAL AND METHODS

A cross-sectional, descriptive study of children, adolescents and young adults with type 1 diabetes. Symptoms of anxiety and depression, and the quality of life were assessed using the Beck's Anxiety and Depression Scales and the pedsQL diabetes module score respectively.

RESULTS

A total of 74 patients were recruited. The mean age was 18 ± 4.1 years. Minimal symptoms of anxiety were noted in 51 (69%) patients, 23 (31%) had non-minimal symptoms of anxiety (mild:14, moderate: 5, severe: 4). Symptoms of depression were absent in 43 (58.1%) patients and present in 31 (41.9%) patients (mild: 19, moderate: 12). The patients total score of quality of life was 65.4. Higher socioeconomic status (p = 0.03) was a protective factor against Symptoms of anxiety, while the age above 14 years (p = 0.01) was a risk factor for symptoms of depression. The quality of life was lower in patients from low socio-economic status (p = 0.01), those with poor glycemic control (p = 0.03), and when symptoms of depression were present (p = 0.02).

CONCLUSIONS

Patients with type 1 diabetes in Congo experienced a significant elevated symptoms of anxiety and depression, and a fairly good quality of life. These findings support recommendations for integrating psychosocial aspects in the management of these patients.

Evaluation of the Relationship between Salivary Lipids, Proteins and Total Antioxidant Capacity with Gingival Health Status in Type-1 Diabetic Children

STATEMENT OF THE PROBLEM

Alteration in salivary composition and its effect on the oral cavity in diabetic child patients remains equivocal.

PURPOSE

This study was performed to assess the relationship between salivary factors and gingival status in children with type-1 diabetes mellitus (DM).

MATERIAL AND METHOD

In this cross-sectional study, 120 subjects aged 6-16 years (60 well-controlled and poorly-controlled diabetics and 60 healthy individuals) were examined to determine the gingival index (GI) and plaque index (PI). The unstimulated saliva samples were collected to measure the salivary triglyceride, cholesterol, albumin, α-amylase, total protein levels by the laboratory kits. Total antioxidant capacity and the free radicals scavenger index were measured by the Ferric Reducing Ability Of Plasma (FRAP) and 1,1-Diphenyl-2-picryl-hydrazyl (DPPH) assays, respectively. Data were analyzed by parametric and non-parametric, Pearson correlation, and t tests at a 5% error level.

RESULTS

GI of diabetics was significantly higher than that of healthy individuals (1.51± 0.71 and 0.9±0.81, respectively, p< 0.001). No significant difference was found between the PI of diabetics compared to healthy volunteers (1.59±0.69, 1.63±0.74, respectively). The levels of salivary triglyceride and cholesterol, albumin and total proteins in healthy subjects were significantly higher than that in people with DM (p< 0.001). A significantly more salivary α-amylase activity was found in diabetics compared to non-diabetics (p< 0.001). No significant differences were found between diabetic and non-diabetic subjects in terms of DPPH (95.5, 95.9%, respectively) and FRAP (9.77±0.13, 9.78±0.12 (µmol/mL), respectively).

CONCLUSION

More gingival inflammation and salivary α-amylase activity and lower level of salivary lipids, albumin, and total proteins were found in diabetic patients, but there was no association between the level of lipids, proteins, and the total antioxidant capacity of saliva with periodontal health indicators in patients with DM and healthy individuals.

Prevalence and course of mood and anxiety disorders, and correlates of symptom severity in adolescents with type 1 diabetes: Results from diabetes LEAP

OBJECTIVES

We aim to determine the prevalence and the course of anxiety and mood disorders in Dutch adolescents (12-18 years old) with type 1 diabetes, and to examine correlates of symptom severity, including parental emotional distress.

METHODS

Participants were 171 adolescents and 149 parents. The Diagnostic Interview Schedule for Children-IV was used to assess current, past year and lifetime anxiety and mood disorders in adolescents. Symptom severity and diabetes distress were measured with validated questionnaires. Correlates of these symptoms were examined using hierarchical regression analyses and included demographics (adolescent sex and age), clinical factors (diabetes duration, treatment modality, most recent glycated hemoglobin A_1c ; all extracted from medical charts), adolescent diabetes distress, and parent emotional distress.

RESULTS

Twenty-four (14%) adolescents met the criteria for ≥1 disorder(s) in the previous 12 months. Anxiety disorders were more prevalent than mood disorders (13% vs. 4%). Lifetime prevalence of anxiety and mood disorders was 29% (n = 49). The presence of any of these disorders earlier in life (from 5 years old up to 12 months prior to assessment) was associated with disorders in the past 12 months (OR = 4.88, p = 0.001). Higher adolescent diabetes distress was related to higher symptoms of anxiety (b = 0.07, p = 0.001) and depression (b = 0.13, p = 0.001), while demographics, clinical characteristics, and parental emotional distress were not related.

CONCLUSIONS

Anxiety and mood disorders are common among adolescents and related to earlier disorders. Higher diabetes distress was related to higher symptom severity. Clinicians are advised to address past psychological problems and remain vigilant of these problems.

Assessment of Psychopathology in Adolescents with Insulin-Dependent Diabetes (IDD) and the Impact on Treatment Management

Assessing mental health in children and adolescents with insulin-dependent diabetes (IDD) is an issue that is underperformed in clinical practice and outpatient clinics. The evaluation of their thoughts, emotions and behaviors has an important role in understanding the interaction between the individual and the disease, the factors that can influence this interaction, as well as the effective methods of intervention. The aim of this study is to identify psychopathology in adolescents with diabetes and the impact on treatment management. A total of 54 adolescents with IDD and 52 adolescents without diabetes, aged 12-18 years, completed APS-SF (Adolescent Psychopathology Scale-Short Form) for the evaluation of psychopathology and adjustment problems. There were no significant differences between adolescents with diabetes and control group regarding psychopathology. Between adolescents with good treatment adherence (HbA1c < 7.6) and those with low treatment adherence (HbA1c > 7.6), significant differences were found. In addition, results showed higher scores in girls compared with boys with IDD with regard to anxiety (GAD), Major Depression (DEP), Post-Traumatic Stress Disorder (PTSD), Eating Disturbance (EAT), Suicide (SUI) and Interpersonal Problems (IPP). No significant differences were found regarding the duration of the disease. Strategies such as maladaptive coping, passivity, distorted conception of the self and the surrounding world and using the negative problem-solving strategies of non-involvement and abandonment had positive correlation with poor glycemic control (bad management of the disease). The study highlighted the importance of promoting mental health in insulin-dependent diabetes management.

Glycemic Outcome Associated With Insulin Pump and Glucose Sensor Use in Children and Adolescents With Type 1 Diabetes. Data From the International Pediatric Registry SWEET

OBJECTIVE

Insulin delivery methods, glucose-monitoring modalities, and related outcomes were examined in a large, international, diverse cohort of children and adolescents with type 1 diabetes from the Better Control in Pediatric and Adolescent Diabetes: Working to Create Centers of Reference (SWEET) -Registry.

RESEARCH DESIGN AND METHODS

Participants with type 1 diabetes of ≥1 year, aged ≤18 years, and who had documented pump or sensor usage during the period August 2017-July 2019 were stratified into four categories: injections-no sensor (referent); injections + sensor; pump-no sensor; and pump + sensor. HbA_1c and proportion of patients with diabetic ketoacidosis (DKA) or severe hypoglycemia (SH) were analyzed; linear and logistic regression models adjusted for demographics, region, and gross domestic product per capita were applied.

RESULTS

Data of 25,654 participants were analyzed. The proportions of participants (adjusted HbA_1c data) by study group were as follows: injections-no sensor group, 37.44% (8.72; 95% CI 8.68-8.75); injections + sensor group, 14.98% (8.30; 95% CI 8.25-8.35); pump-no sensor group, 17.22% (8.07; 95% CI 8.03-8.12); and pump + sensor group, 30.35% (7.81; 95% CI 7.77-7.84). HbA_1c was lower in all categories of participants who used a pump and/or sensor compared with the injections-no sensor treatment method (P < 0.001). The proportion of DKA episodes was lower in participants in the pump + sensor (1.98%; 95% CI 1.64-2.48; P < 0.001) and the pump-no sensor (2.02%; 95% CI 1.64-2.48; P < 0.05) groups when compared with those in the injections-no sensor group (2.91%; 95% CI 2.59-3.31). The proportion of participants experiencing SH was lower in pump-no sensor group (1.10%; 95% CI 0.85-1.43; P < 0.001) but higher in the injections + sensor group (4.25%; 95% CI 3.65-4.95; P < 0.001) compared with the injections-no sensor group (2.35%; 95% CI 2.04-2.71).

CONCLUSIONS

Lower HbA_1c and fewer DKA episodes were observed in participants using either a pump or continuous glucose monitoring (CGM) or both. Pump use was associated with a lower rate of SH. Across SWEET centers, use of pumps and CGM is increasing. The concomitant use of pump and CGM was associated with an additive benefit.

Association of family structure with type 1 diabetes management and outcomes in adolescents: A population-based cross-sectional survey

BACKGROUND

Diabetes therapies have enormously changed during past decades, but only few studies have analyzed the association between family structure and diabetes management and outcomes.

OBJECTIVE

To analyze cross-sectionally the associations of family structure with type 1 diabetes (T1D) management and various diabetes outcomes.

METHODS

A total of 1635 11- to 17-year-old participants and their parents completed one of three baseline surveys as part of a nationwide, population-based cohort study on early-onset, long-standing T1D. Associations between family structure and outcome variables were analyzed by multivariable linear/logistic regression.

RESULTS

Compared to adolescents living with both parents (reference), HbA_1c was 0.48% (95% confidence interval 0.24; 0.71) / 5.2 (2.6; 7.8) mmol/mol higher in adolescents living with one parent and 0.34% (0.08; 0.59) / 3.7 (0.9; 6.5) mmol/mol higher in those living with one parent and her/his partner. The blood glucose self-monitoring (SMBG) frequency was lower (single parent: -0.6 (-1.1; -0.2), parent and partner:-0.5 (-1.0; 0.0)) and parents reported more long-term consequences related to school or work (OR_{single-parent} 1.52 (0.90; 2.57), OR_{parent + partner} 1.50 (0.86; 2.60)). While living with one parent was associated with increased odds of insulin injection vs. insulin pump therapy (OR 1.61 [1.13; 2.29]), the odds of low hypoglycemia awareness (OR 1.75 [1.00; 3.08]) and diabetes complications (1.32 [0.78; 2.22]) were higher in people living with a parent and her/his partner.

CONCLUSIONS

Living with only one parent with or without a new partner was associated with less SMBG and pump use and poor diabetes outcomes. Future studies to explore the underlying mechanisms are required.

Do children and adolescents with type 1 diabetes suffer from a lack of resources in France? Results from a benchmark study in the New Aquitaine region

BACKGROUND

A benchmark study was conducted in the southwest of France, in the New Aquitaine region, to investigate metabolic outcomes and availability of resources in pediatric diabetes units. We assessed whether the level of care was in accordance with the International Society for Pediatric and Adolescent Diabetes recommendations.

METHODS

Demographic and clinical data were collected, as were all HbA1c tests for the 2017 calendar year. Pediatricians specialized in diabetes care were invited to complete an online survey concerning means allocated to the management of type 1 diabetes in their centers.

RESULTS

Sixteen centers provided data for 1277 patients and 3873 clinical visits. A total of 1115 children suffering from diabetes for more than 1 year were studied. Median HbA1c was 8% (7.4-8.6) for the whole region. Only 29.2% of children had good metabolic control in accordance with the <7.5% target. We identified slight but significant variation in glycemic control among centers (P=0.029). The use of an insulin pump varied greatly among centers but did not explain HbA1c differences. We did not identify a correlation between medical or paramedical time dedicated to the follow-up of diabetic patients and the mean HbA1c of each center. For 100 diabetic patients, follow-up was provided by 0.42 physicians (0.23-1.50), 0.15 nurses (0-0.56), 0.12 dietitians (0-0.48), and 0.07 psychologists (0-0.30).

CONCLUSION

This study demonstrates a lack of human resources allocated to the management of type 1 diabetes in the region that is far below international recommendations. The proportion of children achieving the international glycemic target is low. There is a clear need to improve glycemic control in children, which will only be possible with improved professional practices, encouraged by benchmark studies, and by increasing the size of our multidisciplinary teams.

Effect of hospital discharge plan for children with type 1 diabetes on discharge readiness, discharge education quality, and blood glucose control

BACKGROUND

Type 1 diabetes is one of the most common chronic diseases in childhood. The number of type 1 diabetes patients in China still ranks fourth in the world. Therefore, children with type 1 diabetes in China are a group that needs attention. The management of type 1 diabetes mellitus (T1DM) involves many aspects of daily life. It is extremely challenging for children and their families. T1DM children have complex medical care needs. Despite the continuous development of therapeutic medicine and treatment technologies, blood glucose control in children with T1DM is still not ideal. They and their parents need to acquire more knowledge and skills before being discharged.

AIM

To explore the influence of hospital discharge plan based on parental care needs of children with T1DM on discharge readiness, quality of discharge education and blood glucose control level.

METHODS

In total, 102 parents of children with type 1 diabetes were divided into control group and intervention group according to admission time. Fifty cases from February to June 2019 were selected as the control group, and 52 cases from July to October 2019 were selected as the intervention group to implement the discharge plan. The Readiness for Hospital Discharge Scale, Hospital Discharged Education Quality Scale and children's blood glucose metabolism indicators were used to compare the differences in discharge preparation, discharge education quality and blood glucose control between the two groups of children and their parents.

RESULTS

On the day of discharge, the two groups of children had the following scores of readiness for discharge: The intervention group score was 225.34 ± 32.47, and the control group score was 208.68 ± 29.31. The P value was 0.007, and the difference was statistically significant. The discharge education quality scores were as follows: The intervention group score was 135.11 ± 19.86, the control group score was 124.13 ± 15.56, the P value was 0.002 and the difference was statistically significant. Three months after discharge, the blood glucose metabolism indicator showed that the glycosylated hemoglobin value of the two groups was (7.45% ± 1.04%), and that of the control group was (8.04% ± 1.27%), P = 0.012. Therefore, the improvement of parents' readiness for discharge, quality of discharge education and blood glucose metabolism indicators (glycosylated hemoglobin, fasting blood glucose and postprandial blood glucose) in the intervention group were better than those in the control group (P < 0.05), and the difference was statistically significant.

CONCLUSION

The discharge plan for children with T1DM can help the children and their families realize the transition from hospital care to home self-management and improve the parents' readiness for discharge, thereby improving children’s blood glucose control levels.

Effectiveness and equity of continuous subcutaneous insulin infusions in pediatric type 1 diabetes: A systematic review and meta-analysis of the literature

AIMS

We conducted a systematic review and meta-analysis of randomized controlled trials (RCT) and non-randomized studies (NRS) to assess the effectiveness and equity of continuous subcutaneous insulin infusions (CSII) versus multiple-daily injections (MDI) on glycemic outcomes.

METHODS

Searches were conducted between 2000 and 2019 in MEDLINE, CENTRAL, EMBASE and HTA. Included studies compared the CSII vs MDI in children and young people (CYP) ≤ 20 years with type 1 diabetes. Two independent reviewers screened the articles, extracted the data, assessed the risk of bias, evaluated the quality of evidence, and identified equity data. Results were pooled with a random-effects model.

RESULTS

Of the 578 articles screened, 16 RCT (545 CYP on CSII) and 70 NRS (73253 on CSII) were included in the meta-analysis. There was moderate-level evidence that the CSII lower HbA_1c in RCT (pooled mean difference [MD]: -0.22%; 95% confidence interval [CI]: -0.33, -0.11%; I²:34%) and insufficient in NRS (pooled MD: -0.45%; 95%CI: -0.52, -0.38%; I²:99%). The pooled incidence rate ratio of severe hypoglycemia on CSII vs MDI in RCT was 0.87 (95%CI: 0.55, 1.37; I²:0%; low-level evidence), and 0.71 (95%CI: 0.63, 0.81; I²:57%, insufficient evidence) in NRS. Health-related quality of life presented insufficient evidence. Equity data were scarcely reported.

CONCLUSIONS

CSII modestly lower HbA_1c when compared with MDI. Current literature does not provide adequate data on other glycemic outcomes. Future assessment on diabetes technology should include individual and area-level socioeconomic data. The study protocol was pre-registered in PROSPERO (CRD42018116474).

Treatment regimens and glycosylated hemoglobin levels in youth with Type 1 and Type 2 diabetes: Data from SEARCH (United States) and YDR (India) registries

OBJECTIVE

To compare treatment regimens and glycosylated hemoglobin (A1c) levels in Type 1 (T1D) and Type 2 diabetes (T2D) using diabetes registries from two countries-U.S. SEARCH for Diabetes in Youth (SEARCH) and Indian Registry of youth onset diabetes in India (YDR).

METHODS

The SEARCH and YDR data were harmonized to the structure and terminology in the Observational Medical Outcomes Partnership Common Data Model. Data used were from T1D and T2D youth diagnosed <20 years between 2006-2012 for YDR, and 2006, 2008, and 2012 for SEARCH. We compared treatment regimens and A1c levels across the two registries.

RESULTS

There were 4003 T1D (SEARCH = 1899; YDR = 2104) and 611 T2D (SEARCH = 384; YDR = 227) youth. The mean A1c was higher in YDR compared to SEARCH (T1D:11.0% ± 2.9% vs 7.8% ± 1.7%, P < .001; T2D:9.9% ± 2.8% vs 7.2% ± 2.1%, P < .001). Among T1D youth in SEARCH, 65.1% were on a basal/bolus regimen, whereas in YDR, 52.8% were on once/twice daily insulin regimen. Pumps were used by 16.2% of SEARCH and 1.5% of YDR youth with T1D. Among T2D youth, in SEARCH and YDR, a majority were on metformin only (43.0% vs 30.0%), followed by insulin + any oral hypoglycemic agents (26.3% vs 13.7%) and insulin only (12.8% vs 18.9%), respectively.

CONCLUSION

We found significant differences between SEARCH and YDR in treatment patterns in T1D and T2D. A1c levels were higher in YDR than SEARCH youth, for both T1D and T2D, irrespective of the regimens used. Efforts to achieve better glycemic control for youth are urgently needed to reduce the risk of long-term complications.

This guidance document presents recommendations and a useful algorithm for the use of a standardized glucose reporting system in the routine diabetes care setting.

Socioeconomic position is associated with glycemic control in youth and young adults with type 1 diabetes

OBJECTIVE

Health inequities persist in youth and young adults (YYA) with type 1diabetes in achieving optimal glycemic control. The purpose of this study was to assess the contribution of multiple indicators of social need to these inequities.

RESEARCH DESIGN AND METHODS

Two hundred and twenty two YYA withtype 1 diabetes enrolled in the SEARCH Food Insecurity Study in South Carolina and Washington between the years 2013 and 2015 were included. Latent class analysis was used to identify socioeconomic profiles based on household income, parental education, health insurance, household food insecurity, and food assistance. Profiles were evaluated in relation to glycemic control using multivariable linear and logistic regression, with HbA1c > 9%(75 mmol/mol) defined as high-risk glycemic control.

RESULTS

Two profiles were identified: a lower socioeconomic profile included YYA whose parents had lower income and/or education, and were more likely to be uninsured, receive food assistance, and be food insecure. A higher socioeconomic profile included YYA whose circumstances were opposite to those in the lower socioeconomic profile. Those with a lower socioeconomic profile were more likely to have high-risk glycemic control relative to those with a higher socioeconomic profile (OR = 2.24, 95%CI = 1.16-4.33).

CONCLUSIONS

Lower socioeconomic profiles are associated with high-risk glycemic control among YYA with type 1 diabetes. This supports recommendations that care providers of YYA with type 1 diabetes assess individual social needs in tailoring diabetes management plans to the social context of the patient.

Assessment of self-monitoring of blood glucose in type 1 diabetic children and adolescents and its influence on quality of life: practice and perspective

Background

Self-monitoring blood glucose (SMBG) includes an assessment of the capillary glucose concentration as well as the interpretation of and responding to the readings. The purpose of this study was to assess patients’ compliance to self-monitoring blood glucose (SMBG), identify factors and barriers that affect it, and to correlate performance of SMBG to blood glucose monitoring and patients’ quality of life. Three hundred and thirty children and adolescents with type 1 diabetes were subjected to the following: (1) an interview pre-structured questionnaire which included personal, medical history, and details about SMBG; (2) Questionnaire about Quality of Life Index (Diabetes Version-III) by Ferrans and Powers for patients aging 10–16 years; and (3) glycated hemoglobin (HA1C) measurement.

Results

About 67% of the patients assessed their blood glucose 3 times per day, while 0.57% assessed blood glucose 7 times. The most influential factors affecting compliance of SMBG were the cost of strips and glucometers, the fear of pain and injection, psychological frustration, lack of availability of information to deal with high reading, and the absence of motivation for doing regular SMBG.

The more the frequency of SMBG daily, the better the HA1C of the patients (p < 0.01).

Adolescent patients aged 10–16 years who have more frequent SMBG and those with less HA1C have significant better quality of life (p < 0.05).

Conclusions

More frequent SMBG practice was associated with better glycemic control and better quality of life. Patients’ compliance is influenced by several factors which affect their frequency of SMBG.

Effects of advanced carbohydrate counting on glucose control and quality of life in children with type 1 diabetes

OBJECTIVE

The effect of advanced carbohydrate counting (ACC) on metabolic and quality of life (QOL) outcomes is uncertain in children with type 1 diabetes. Our aim was to determine whether ACC would improve HbA1c and QOL scores as compared with standard nutrition in this population.

METHODS

We randomized 87 patients using pump and rapid-acting analogs in a 1 year randomized multicenter study (age 9.6 ± 3.5 years, diabetes duration 4.6 ± 2.7 years, HbA1c 7.8 ± 0.5% [62 ± 5 mmol/mol]). The ACC group received CC education and the control group received traditional dietary education. HbA1c was measured every 3 months. At 0 and 1 year, general, diabetes-specific, and diet-related QOL were respectively assessed by the KIDSCREEN and WHO-5 questionnaires, the diabetes-specific module of the DISABKIDS, and the diet restriction items of the DSQOLS.

RESULTS

Mean HbA1c was lower in the ACC than the control group at 3 months (P < .05) and tended to be lower at 6 months (P = .10), 9 months (P = .10), but not at 12 months. The mean of individual average HbA1c during the one-year study period (from M3 to M12) was 7.63 ± 0.43 in the ACC vs 7.85 ± 0.47% in the control group (60 ± 5 vs 62 ± 5 mmol/mol)(P < .05). ACC was associated with significantly higher scores at 1 year on the KIDSCREEN children's psychological scale and the KIDSCREEN parents' physical scale, the DISABKIDS children's treatment scale, and the children's and parents' dietary restriction scales of the DSQOLS (indicating better QOL or lower perceived diet restriction).

CONCLUSIONS

ACC may be associated with small improvements in metabolic control and QOL scores in children.

Effect of 6 Months of Flash Glucose Monitoring in Youth With Type 1 Diabetes and High-Risk Glycemic Control: A Randomized Controlled Trial

OBJECTIVE

To investigate whether intermittently scanned continuous glucose monitoring (isCGM) significantly improves glycemic control compared with capillary self-monitored blood glucose (SMBG) in youth with type 1 diabetes and high-risk glycemic control.

RESEARCH DESIGN AND METHODS

This multicenter 6-month randomized, controlled, parallel-arm trial included 64 participants aged 13-20 years with established type 1 diabetes and glycated hemoglobin (HbA_1c) ≥9% (≥75 mmol/mol). Participants were allocated to 6-month intervention (isCGM; FreeStyle Libre; Abbott Diabetes Care, Witney, U.K.) (n = 33) or control (SMBG; n = 31) using minimization. The primary outcome was the difference in change in HbA_1c from baseline to 6 months.

RESULTS

There was no evidence of a difference between groups for changes in HbA_1c at 6 months (adjusted mean 0.2% greater improvement for isCGM [95% CI -0.9 to 0.5] [-2.1 mmol/mol (95% CI -9.6 to 5.4)]; P = 0.576). However, glucose-monitoring frequency was 2.83 (95% CI 1.72-4.65; P < 0.001) times higher in the isCGM group compared with that in the SMBG group at 6 months. The change in the Diabetes Treatment Satisfaction Questionnaire mean item score also favored isCGM at 6 months (P = 0.048), with no significant differences between groups for fear of hypoglycemia and quality of life (both general and diabetes specific) (all P > 0.1).

CONCLUSIONS

For youth with high-risk glycemic control, isCGM led to improvements in glucose testing frequency and diabetes treatment satisfaction. However, these did not translate to greater improvement in glycemic control over usual care with SMBG at 6 months.

Advances in glucose monitoring: Improving diabetes management through evidence-based medicine

After 50 years SMBG use remains equivocal. CGM, may face the same fate. While it has been reported that CGM use results in improved HbA_1c, the margin is small, and the studies scant. Like SMBG, CGM was introduced as "here's something new, try it." For CGM's potential to be fully realized it must be understood that it can discover underlying metabolic perturbations that would otherwise go undetected; it can measure the frequency, duration, magnitude and distribution of glucose exposure, variability and stability under conditions of daily living which in turn lead to more precise therapies, resulting in improved outcomes.

A pilot non-inferiority randomized controlled trial to assess automatic adjustments of insulin doses in adolescents with type 1 diabetes on multiple daily injections therapy

BACKGROUND

Multiple daily injections (MDI) therapy for type 1 diabetes involves basal and bolus insulin doses. Non-optimal insulin doses contribute to the lack of satisfactory glycemic control. We aimed to evaluate the feasibility of an algorithm that optimizes daily basal and bolus doses using glucose monitoring systems for MDI therapy users.

METHODS

We performed a pilot, non-inferiority, randomized, parallel study at a diabetes camp comparing basal-bolus insulin dose adjustments made by camp physicians (PA) and a learning algorithm (LA), in children and adolescents on MDI therapy. Participants wore a glucose sensor and underwent 11 days of daily dose adjustments in either arm. Algorithm adjustments were reviewed and approved by a physician. The last 7 days were examined for outcomes.

RESULTS

Twenty-one youths (age 13.3 [SD, 3.7] years; 13 females; HbA1c 8.6% [SD, 1.8]) were randomized to either group (LA [n = 10] or PA [n = 11]). The algorithm made 293 adjustments with a 92% acceptance rate from the camp physicians. In the last 7 days, the time in target glucose (3.9-10 mmol/L) in LA (39.5%, SD, 20.7) was similar to PA (38.4%, SD, 15.6) (P = .89). The number of hypoglycemic events per day in LA (0.3, IQR, [0.1-0.6]) was similar to PA (0.2, IQR, [0.0-0.4]) (P = .42). There was no incidence of severe hypoglycemia nor ketoacidosis.

CONCLUSIONS

In this pilot study, glycemic outcomes in the LA group were similar to the PA group. This algorithm has the potential to facilitate MDI therapy, and longer and larger studies are warranted.

Heart Rate Variability and Cardiorespiratory Fitness in Non-Hispanic Black Versus Non-Hispanic White Adolescents With Type 1 Diabetes

BACKGROUND

Evidence indicates that fewer non-Hispanic black versus non-Hispanic white youths with type 1 diabetes are meeting treatment goals for optimal glycemic outcomes, predisposing them to risks for cardiovascular (CV) morbidity and mortality in adulthood.

PURPOSE

We sought to assess the association of sex and race with heart rate variability (HRV) and cardiorespiratory fitness in adolescents with type 1 diabetes. The association between the HRV and cardiorespiratory outcomes with glucose control was also examined.

METHODS

A secondary data analysis of 95 adolescents with type 1 diabetes (n = 66 non-Hispanic white n = 29 non-Hispanic black) was used. Using 24-hour Holter recordings, spectral and time domain measures of HRV were obtained. Cardiorespiratory fitness using a graded exercise test was completed. Descriptive statistics and Pearson correlation coefficients were used to assess associations between glucose control and study outcomes, and general linear models were applied to explore and quantify associations of sex and race with HRV and cardiorespiratory fitness.

RESULTS

Body mass index (mean [standard deviation]) was similar between non-Hispanic black (23.5 [3.9]) and non-Hispanic white (22.7 [3.8]) adolescents. Females and non-Hispanic black adolescents had significantly lower HRV and cardiorespiratory fitness levels. Moderate associations were found between lower HRV and poorer glycemic control (HbA1c). Recent HbA1c was significantly higher in non-Hispanic black (9.7 [1.8]) than non-Hispanic white (8.2 [1.2]).

CONCLUSION

Findings support the importance of early identification of CV health risks in adolescents with type 1 diabetes, particularly for non-Hispanic black adolescents. Interventions focused on overall improvement in glycemic control for adolescents with type 1 diabetes are a priority for minimizing future CV complications.
