Mechanisms underlying the development of eating disorders and disordered eating in adolescent females with type 1 diabetes.

OBJECTIVE: People with Type 1 diabetes (T1D) face an increased risk of eating disorders/disordered eating (ED/DE), with adolescents being particularly vulnerable. Empirical knowledge on the mechanisms underlying development of ED/DE in T1D is crucial for evolving prevention strategies. RESEARCH DESIGN AND METHODS: Fourteen semi-structured interviews with adolescent females with T1D and ED/DE between 14 and 18 years were conducted and analyzed using reflexive thematic analysis. RESULTS: Analyses identified four main themes; 'Interconnected afflictions', 'Judgment', 'Feeling Different', and 'Chaos & Control', These themes explore the interconnectedness of T1D and ED/DE, with shame and guilt emerging as common underlying mechanism. The development of a biopsychosocial model was based on the integration of these data with existing models. CONCLUSIONS: The study extends previous developmental pathways of ED/DE in adolescents with T1D. We propose a biopsychosocial model that incorporates various factors: predisposing factors such as parental management of T1D and weight gain during adolescence; precipitating factors including comments on weight, frequency of weighing, perceptions of surveillance; the perpetuating bilateral influence of ED/DE and T1D and finally highlighting the protective mechanisms of disease acceptance encompassing parental handling of diagnosis and the contribution of healthcare professionals (HCP's) role in psychoeducation. The present study highlight the vulnerability of adolescence in the presence of T1D, particularly concerning issues related to eating, weight, and body. It offers clinically relevant insights, with the aim to improve communication and management strategies for this very specific group.

Effects of lifestyle intervention on IGF-1, IGFBP-3, and insulin resistance in children with obesity with or without metabolic-associated fatty liver disease.

Obesity is a strong predictor for metabolic associated fatty liver disease (MAFLD), which has been associated with decreased insulin like growth factor 1 (IGF-1). In obesity, weight loss increases growth hormone secretion, but this is not unequivocally associated with increases in serum IGF-1 and IGF binding protein-3 (IGFBP-3). We studied the changes in the IGF axis in relation to weight loss and improvement in insulin resistance in children with or without MALFD after 10 weeks of lifestyle intervention at a weight loss camp (WLC). We investigated 113 (66 females) Caucasian children with obesity, median age 12.4 (range 7.3-14.6) years, before and after 10 weeks of lifestyle intervention at a WLC. We investigated children who was either MAFLD positive (n = 54) or negative (n = 59) before and after WLC. Children with MAFLD had lower baseline IGF-1 (249 ± 112 vs 278 ± 107 µg/l, P = 0.048), whereas the IGF-1/IGFBP-3 molar ratio was similar to children without MAFLD (19.4 ± 6.6 vs. 21.8 ± 6.6%, P = 0.108). When all children were considered as one group, WLC decreased SDS-BMI and HOMA-IR (P < 0.001, both) and increased IGF-1 (264 ± 110 vs 285 ± 108 µg/l, P < 0.001) and the IGF/IGFBP-3 molar ratio (20.7 ± 6.7 vs 22.4 ± 6.1%, P < 0.001). When categorized according to liver status, IGF-1 increased significantly in children with MAFLD (P = 0.008) and tended to increase in children without MAFLD (P = 0.052).   Conclusions: Ten weeks of lifestyle intervention decreased insulin resistance and improved the IGF axis. We observed slight differences in the IGF axis in relation to MAFLD status. This suggests that the IGF axis is primarily influenced by insulin resistance rather than MAFLD status. What is New: • Weight loss decreases insulin resistance and subsequently increases the IGF axis in children with obesity. • Children with MAFLD had an aberration in the IGF axis compared to their MAFLD negative counter parts and the IGF axis was primarily influenced by the decreased BMI-SDS and insulin resistance, rather than MAFLD status. What is Known: • NAFLD has previously been associated with reduced serum IGF-1 concentrations. • Data on the impact of MAFLD and aberrations in the growth hormone and IGF axis and the effects of lifestyle interventions in children are limited.

Sweat gland nerve fiber density and association with sudomotor function, symptoms, and risk factors in adolescents with type 1 diabetes.

PURPOSE: To quantify sweat gland nerve fiber density in adolescents with diabetes. Additionally, to investigate associations between sudomotor innervation, sweat responses, and possible risk factors for sudomotor neuropathy. METHODS: Cross-sectional study where 60 adolescents with type 1 diabetes (duration > 5 years) and 23 control subjects were included. Clinical data, quantitative sudomotor axon reflex test, and skin biopsies were obtained. Skin tissue was immunostained and imaged by confocal microscopy. Quantification of the sweat gland volume and three-dimensional reconstruction of the nerve fibers was performed using a design-unbiased technique. RESULTS: Adolescents with diabetes had a significant reduction of maximum and mean values of nerve fiber length and nerve fiber density in sweat glands compared to controls (p values < 0.05). No association between nerve fiber density and sweat responses was found (p = 0.21). In cases with reduced sweat gland nerve fiber length, nerve fiber density, and volume, the sweat response was reduced or absent. Height, systolic blood pressure, time in hypoglycemia, and total daily and basal/total insulin dose were positively correlated to sweat response, while low-density lipoprotein, and HbA1c were negatively correlated with sweat response (p values < 0.05). Other microvascular complications and high cholesterol levels increased the relative risk for reduced sweat gland nerve fiber density. CONCLUSION: Our findings of reduced sweat gland innervation in a selected group of adolescents add new knowledge about the structural changes that occur in autonomic nerves due to diabetes. Evaluating both the sweat gland innervation and sweat gland volume was important for understanding the association with sweat responses. Further research is needed to understand its clinical relevance.

Patients' perspectives on screening for disordered eating among adolescents with type 1 diabetes.

PURPOSE: People with type 1 diabetes have an increased risk of disordered eating (DE) and eating disorders (ED). Screening is recommended however little is known about patients' perspectives on screening questionnaires. This paper reports qualitative analyses of patients' perspectives on the questionnaire Diabetes Eating Problem Survey Revised (DEPS-R), including acceptability, attitudes, and cognitive understanding. RESEARCH DESIGN AND METHODS: 15 adolescents with type 1 diabetes between 11 and 18 years, were interviewed. A semi-structured format and a qualitative Interpretive Descriptive (ID) methodology was chosen. RESULTS: The analyses identified four themes: (1) The Questionnaire, (2) Reframing Diabetes Visits, (3) This is (not) for me, and (4) Out in the Open. The DEPS-R was completed with-in 5-10 min. with no technical difficulties. The questionnaire altered the diabetes visit for some, creating a new dialog, and time for self-reflection. Adolescents appreciated the direct approach in the questionnaire, and showed willingness to complete the questionnaire, when presented to them by a health care professional (HCP). One item in the DEPS-R proved difficult to understand for some participants. CONCLUSION: The study highlights DEPS-R as a clinically relevant screening questionnaire. Completing DEPS-R prior to a consultation opens the door to a consultation that invites the adolescent to address matters of eating behavior. Our findings suggest that systematic screening of DE/ED using the DEPS-R is both accepted and welcomed by adolescents with type 1 diabetes. Future research should focus on a potential update of selected items in DEPS-R. LEVEL OF EVIDENCE: V - qualitative study.

Episodes of severe hypoglycemia is associated with a progressive increase in hemoglobin A1c in children and adolescents with type 1 diabetes.

OBJECTIVE: To investigate the trajectory in glycemic control following episodes of severe hypoglycemia (SH) among children and adolescents with type 1 diabetes (T1D). METHODS: A Danish national population-based study comprising data from 2008-17. SH was defined according to the 2014 ISPAD guidelines. A mixed model was applied with HbA1c as outcome and SH episodes and time since first episode as explanatory variables. Data were adjusted for age, gender and diabetes duration. RESULTS: A total of 4244 children (51.6% boys) with 18 793 annual outpatient visits were included. Mean (SD) age at diabetes onset was 9.0 (4.1) years. Median diabetes duration at inclusion in the study was 1.2 (Q1 = 0.9, Q3 = 3.0) years, and median diabetes duration at last visit was 5.0 (Q1 = 2.7, Q3 = 8.1) years. A total of 506 children experienced at least one episode of SH during the nine-year follow-up; 294 children experienced one episode, 115 two episodes and 97 three or more episodes of SH. HbA1c increased with episodes of SH and in the years following the first episode. The glycemic trajectory peaked 2 to 3 years after an SH episode. The accumulated deterioration in glycemic control was in the range of 5% in patients with two or more episodes equivalent to an increase in HbA1c of 4 mmol/mol (HbA1c ~0.4%). CONCLUSION: SH was followed by a progressive and lasting increase in HbA1c among Danish children and adolescents with T1D. Thus, in addition to the known risk of new episodes of hypoglycemia and cognitive impairment, SH contributes to long-term diabetes complications.

Screening for retinopathy in children with type 1 diabetes in Denmark.

BACKGROUND/OBJECTIVE: Children with type 1 diabetes (T1D) are screened regularly for retinopathy with fundus photography to prevent visual impairment. According to Danish national guidelines, screening should take place at age 12, 15, and 18 years after minimum 3 years of diabetes. As glycemic control has improved, prevalence of retinopathy is expected to be decreased. The aim of this study is to investigate the prevalence, degree, and progression of retinopathy in children with T1D and to explore if screening at 12 years is currently indicated in Denmark. METHODS: Data on all Danish children with onset of T1D from 2003 to 2013 (n = 2943) were collected from the "DanDiabKids" registry. For children with registered screenings (n = 2382), prevalence of retinopathy at 12, 15, and 18 years was determined. In children with retinopathy, subsequent screenings were studied to reveal if retinopathy was persistent or temporary. RESULTS: Prevalence of retinopathy at 12, 15, and 18 years was 0.9%, 2.3%, and 3.1%, respectively. Minimal background retinopathy was seen in over 90% and 100% at 12 years. In available re-screenings, retinopathy resolved spontaneously in 87.5% of all cases and 100% of cases at 12 years. CONCLUSIONS: The prevalence of retinopathy in Danish children with T1D was low. At 12 years, prevalence was 0.9% and exclusively minimal background retinopathy with 100% remission in re-screenings. Thus, screening at this age does not seem to have significant clinical relevance. We propose more individualized screening selection before the age of 15.

Childhood body mass index in relation to subsequent risk of type 1 diabetes-A Danish cohort study.

The incidence of type 1 diabetes (T1D) is increasing, and obesity may be a contributing factor by increasing the risk and accelerating the onset. We investigated the relation between childhood body mass index z-scores (BMIz) and the later risk of T1D, including association with age at onset of T1D. The study included 238 cases and 10 147 controls selected from the Copenhagen School Health Record Register (CSHRR). Cases of T1D were identified in the Danish Registry of Childhood and Adolescent Diabetes and 2 regional studies and linked to CSHRR. Using conditional logistic regression models, the association of childhood prediagnostic BMIz at 7 and 13 years of age and changes between these ages with subsequent risk (odds ratio, OR) of T1D was estimated. A greater BMIz at 7 and 13 years of age was associated with increased risk of T1D with OR of 1.23 (confidence interval, CI 1.09-1.37; P = .0001) and 1.20 (CI 1.04-1.40; P = .016), respectively. The risk was increased by upward changes in z-scores from birth to 7 years (OR=1.21, P = .003) and from 7 to 13 years of age (OR=1.95, P = .023), but in the latter age interval also by a decline in BMIz (OR = 1.91, P = .034). There were no associations between BMIz at 7 and 13 years of age and the age of onset (P = .34 and P = .42, respectively). Increased BMIz is associated with a moderate increase in risk of T1D, but with no relation to age at onset within the analyzed age range. Increased BMIz over time is unlikely to explain the rising incidence of T1D.

Prevalence, Safety, and Metabolic Control Among Danish Children and Adolescents with Type 1 Diabetes Using Open-Source Automated Insulin Delivery Systems.

Background: Treatment of type 1 diabetes mellitus (T1DM) has become increasingly technical with rapid developments in integration of pumps and sensors to regulate insulin dosage, and patient-initiated solutions as open-source automated insulin delivery (OS-AID) systems, have gained popularity in people with diabetes. Studies have shown increased glycemic control and mental wellbeing in users of OS-AID systems. The aim of this study was to estimate the prevalence, the effect on metabolic control, the risk, and the effect on everyday life for users and their parents of OS-AID systems in Danish children and adolescents with T1DM. Methods: This retrospective cohort study recruited participants through pediatric diabetes outpatient clinics and social media. Surveys were distributed and current and retrospective data on glycemic control (HbA1c, time in range [TIR] etc.) were collected. Results: Fifty-six users of OS-AID systems out of 2950 Danish children and adolescents with T1DM were identified from all outpatient clinics in Denmark. Thirty-one responded on contact and were included (55% of the identified), median age 12 [interquartile range: 11-14] years, 51% females, and mean duration of use of OS-AID systems 2.37 ± 0.86 years. Glycemic control increased significantly with TIR increasing from mean 62.29% ± 13.68% to 70.12% ± 10.08%, *P < 0.01, and HbA1c decreasing from mean 50.13 ± 5.76 mmol/mol (6.7% ± 2.7%) to 47.86 ± 6.24 mmol/mol (6.5% ± 2.7%), **P < 0.05. No changes were found in safety parameters. Parents reported better quality of sleep evaluated by Pittsburgh Sleep Quality Index. Conclusion: This study is the first to provide knowledge on pediatric users of OS-AID systems in Denmark and found a prevalence of 1.89% for OS-AID systems, improved TIR, and no increased risk associated with use of OS-AID systems.

Bladder dysfunction in adolescents with type 1 diabetes.

BACKGROUND: It is increasingly significant that adults with diabetes experience lower urinary tract symptoms, however, there has been limited research in younger individuals with type 1 diabetes. OBJECTIVE: To investigate bladder function using non-invasive urodynamics as a potential indicator of autonomic neuropathy in adolescents with type 1 diabetes. This involved examining the association between urinary flow disturbances, reported symptoms, and results from other autonomic tests. STUDY DESIGN: Cross-sectional study enrolling 49 adolescents with type 1 diabetes and 18 control subjects. All participants underwent uroflowmetry and ultrasound scanning, completed the Composite Autonomic Symptom Score (COMPASS)-31 questionnaire, and were instructed to record their morning urine volume and voiding frequencies and report them back. Cardiovascular reflex tests (CARTs) and the quantitative sudomotor axon reflex test (QSART) were performed. RESULTS: The main results are shown in the Summary figure. DISCUSSION: In this study, urological abnormalities were not significantly more frequent in adolescents with diabetes, however, urological issues were observed. This is supported by previous findings of Szabo et al. who found that adolescents with type 1 diabetes had reduced flow acceleration and time to maximum flow compared to control subjects. In our study, we observed cases with reduced acceleration and prolonged uroflow curves, possibly indicating detrusor underactivity. People with diabetes had a higher risk of nocturia than healthy controls, which our results supported. Some adolescents reported urination twice per night. Based on these findings, it is considered beneficial to ask about urological symptoms annually to determine if more examinations (frequency-volume charts and uroflowmetry) are necessary and/or if any opportunities for treatment optimization exist. However, uroflowmetry has limitations, as bladder filling and emptying is a complex process involving multiple pathways and neurological centers, making it difficult to standardize and evaluate. Another limitation of this study was that our control group was smaller and consisted of fewer males than females, which could affect the results due to differences in anatomy and physiology in the lower urinary tract system. CONCLUSION: In conclusion, adolescents with type 1 diabetes, as well as healthy adolescents, frequently experience urological symptoms. Although urological abnormalities were not significantly more frequent in adolescents with diabetes in this study, the focus on nocturia and risk for bladder dysfunction seems relevant, even in adolescents without any other tests indicating autonomic dysfunction.

INfluenza VaccInation To mitigate typE 1 Diabetes (INVITED): a study protocol for a randomised, double-blind, placebo-controlled clinical trial in children and adolescents with recent-onset type 1 diabetes.

INTRODUCTION: Children and adolescents with recent-onset type 1 diabetes (T1D) commonly maintain a certain level of insulin production during the remission phase, which can last months to years. Preserving ß-cell function can reduce T1D complications and improve glycaemic control. Influenza vaccination has pleiotropic effects and administration of the vaccine during the early phases of T1D may offer ß-cell protection. This study aims to assess the effect of influenza vaccination on preserving ß-cell function in children and adolescents with recent-onset T1D. METHODS AND ANALYSIS: The INfluenza VaccInation To mitigate typE 1 Diabetes trial is a randomised, double-blind, placebo-controlled, multicentre trial in paediatric patients with recent-onset T1D aged 7-17 years. 100 participants will be randomised in a 1:1 ratio to receive either a standard inactivated quadrivalent influenza vaccine or a placebo within 14 days of diagnosis. The primary outcome is a difference in mean change (from baseline to 12 months) in C-peptide level between groups during a 2-hour mixed-meal tolerance test. Secondary outcomes include mean change (from baseline to 6 months) in C-peptide levels, haemoglobin A1c, ambulatory glucose profiles and insulin requirements. Exploratory outcomes are diabetes-related autoantibodies, inflammatory markers and serum haemagglutinin inhibition antibody titres against the influenza viruses. The current treatment for T1D is largely symptomatic, relying on insulin administration. There is a pressing need for novel pharmacological approaches aimed at modulating the immune system to preserve residual ß-cell function. Existing immunotherapies are cost-prohibitive and associated with multiple side effects, whereas influenza vaccination is inexpensive and generally well tolerated. A positive outcome of this study holds potential for immediate implementation into standard care for children and adolescents with recent-onset T1D and may guide future research on immune modulation in T1D. ETHICS AND DISSEMINATION: Ethical approval was obtained from Danish Health Authorities prior to participant enrollment. The trial results will be submitted to a peer-reviewed journal. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov NCT05585983 and EudraCT Number 2022-500906-17-01.

Diabetes Management Support in Preschool and Primary School: A Qualitative Ideation Study Presenting Recommendations for Improved Communicative Practice.

Diabetes care in institutional settings is a significant challenge that affects the whole family as well as care workers and teachers. The present study is the ideation part of a rigorous development process in the KIds with Diabetes in School (KIDS) project. We have previously conducted a thorough three-part needs assessment in which we explored the problem area from the viewpoints of (1) municipal administrative staff, (2) preschool and school staff and (3) families. Based on the identified needs and to a great extent on the contents and shortcomings of existing guidelines, the objective of the present study is to explore and develop possible solutions and recommendations for addressing the challenges and problems. To meet this objective, we held comprehensive multistakeholder participatory workshops in each of the five Danish regions. Five main themes with multiple subthemes were identified as areas to be addressed: (1) training and knowledge, (2) communication and collaboration, (3) the designated contact/support person, (4) national guidelines, and (5) the Diabetes Coordinator. Our findings demonstrate that communicative structures and dynamics are at the very heart of the identified problems and challenges and that the possible solutions should revolve around improving existing structures and highlighting the importance of constantly working on understanding and developing communication strategies. We propose a set of recommendations for practice based on these communicative needs.

Copeptin levels increase in response to both insulin-induced hypoglycemia and arginine but not to clonidine: data from GH-stimulation tests.

Background: The diagnosis of the polyuria-polydipsia syndrome is challenging. Copeptin is a robust biomarker of arginine vasopressin (AVP) secretion. Arginine, which stimulates growth hormone (GH), has been shown also to stimulate copeptin secretion via unknown mechanisms. Aim: The aim was to investigate copeptin levels in response to three different GH stimulation tests in patients suspected of GH deficiency. Methods: In this cross-sectional study, we measured plasma copeptin levels at baseline and at 60, 105, and 150 min in patients undergoing a stimulation test for growth hormone deficiency with either arginine (n = 16), clonidine (n = 8) or the insulin tolerance test (ITT) (n = 10). Results: In patients undergoing the arginine test, the mean age was 9 years, and 10 years for clonidine. The ITT was only performed in adult patients (>18 years) with a mean age of 49 years. Copeptin level increased significantly from baseline to 60 min after arginine (P <0.01) and ITT (P < 0.01). By contrast, copeptin level tended to decrease after clonidine stimulation (P = 0.14). Conclusion: These data support that infusion of arginine increases plasma copeptin levels and reveal a comparable response after an ITT. We hypothesize that the underlying mechanism is abrogation of somatostatin-induced AVP suppression.

Patient-reported outcome instruments for assessing the involvement of children and adolescents with type 1 diabetes in their treatment: a scoping review protocol.

OBJECTIVE: The objective of this review is to identify available patient-reported outcome instruments used to assess the involvement of children and adolescents with type 1 diabetes in their treatment. Specifically, this review will examine the content, structure, and application of these instruments. INTRODUCTION: It is considered meaningful to involve children and adolescents living with a chronic health condition, such as type 1 diabetes, in their own treatment. Despite a growing interest in patient involvement within pediatric health care, including the use of patient-reported outcomes, only a few patient-reported outcome instruments have been developed and are used to evaluate the experiences of children and adolescents with type 1 diabetes of being involved in their own treatment. INCLUSION CRITERIA: This scoping review will examine patient-reported outcome instruments used to assess the experiences of children and adolescents (11 to 18 years of age) with type 1 diabetes of being involved in their own care. Patient-reported outcome instruments measuring parents' or clinicians' experiences of involvement will be excluded. METHODS: The proposed review will follow JBI guidelines and all stages will involve 2 or more reviewers. PubMed, Embase, CINAHL, PsycINFO, JSTOR, and MedNar will be searched without limitations on the year or language of publication. Literature that is not written in English will be translated. Data extraction, charting, and analysis will be guided by a template developed for this review that focuses on the content, structure, and application of the patient-reported outcome instruments. Any modifications to the extraction template will be detailed in the review, and data will be presented in a descriptive format.

Cross-sectional study investigating the association between inflammatory biomarkers and neuropathy in adolescents with type 1 diabetes.

OBJECTIVES: The aims of this study were to investigate circulating levels of inflammatory markers in adolescents with type 1 diabetes with and without different types of neuropathies and evaluate the association between inflammatory biomarkers, nerve function and clinical parameters. DESIGN: Cross-sectional study. SETTING: Hospitals and Steno Diabetes Center in Denmark. PARTICIPANTS: Adolescents with more than 5 years of diabetes duration were investigated for large fibre, small fibre and autonomic neuropathy as a part of the T1DANES study. Blood samples from the participants were analysed for inflammatory biomarkers by Meso Scale Discovery multiplexing technology. PRIMARY AND SECONDARY OUTCOME MEASURES: Inflammatory biomarkers and results of diagnostic nerve tests. RESULTS: Fifty-six adolescents with type 1 diabetes and 23 healthy controls were included. The adolescents with diabetes had significantly higher interferon-gamma, tumour necrosis factor-alpha (TNF-a), interleukin (IL)-10 and soluble urokinase plasminogen activator receptor (suPAR) compared with healthy controls (p values<0.05). TNF-a was higher in the adolescents with large fibre neuropathy (LFN) (p=0.03) compared with those without LFN in the group with diabetes. A negative correlation was seen between TNF-a and conduction velocity in nervus tibialis (p=0.04), and higher TNF-a and IL-6 were associated with higher gastric motility index (TNF-a, p value=0.03; IL-6, p value=0.02). There were no significant associations between inflammatory markers and expressed symptoms, haemoglobin A1c, diabetes duration or body mass index standard derivation score (p values>0.05). The receiver operating characteristic (ROC) curves for the inflammatory markers suggested them as poor screening methods for all types of neuropathies with an area under the curve between 0.47 and 0.67. CONCLUSION: Our results confirm increased low-grade inflammation in adolescents with type 1 diabetes. TNF-a was higher in adolescents with LFN and correlated negatively with nervus tibialis conduction velocity. The other inflammatory biomarkers fail to support differences in those with and without different types of diabetic neuropathies. However, TNF-a and IL-6 were positively correlated to gastric motility index.

Involving children and adolescents with type 1 diabetes in health care: a qualitative study of the use of patient-reported outcomes.

BACKGROUND: Within pediatric health care services, Patient-reported Outcomes (PROs) regarding the patient's health status are mainly used for research purposes in a chronic care setting. However, PROs are also applied in clinical settings in the routine care of children and adolescents with chronic health conditions. PROs have the potential to involve patients because they 'place the patient at the center' of his or her treatment. The investigation of how PROs are used in the treatment of children and adolescents and how this use can influence the involvement of these patients is still limited. The aim of this study was to investigate how children and adolescents with type 1 diabetes (T1D) experience the use of PROs in their treatment with a focus on the experience of involvement. RESULTS: Employing Interpretive Description, 20 semi-structured interviews were conducted with children and adolescents with T1D. The analysis revealed four themes related to the use of PROs: Making room for conversation, Applying PROs under the right circumstances, Questionnaire structure and content, and Becoming partners in health care. CONCLUSIONS: The results clarify that, to some extent, PROs fulfill the potential they promise, including patient-centered communication, detection of unrecognized problems, a strengthened patient-clinician (and parent-clinician) partnership, and increased patient self-reflection. However, adjustments and improvements are needed if the potential of PROs is to be fully achieved in the treatment of children and adolescents.

Neuropathy in adolescents with type 1 diabetes: Confirmatory diagnostic tests, bedside tests, and risk factors.

AIMS: To estimate the prevalence of large fiber (LFN), small fiber (SFN), and autonomic neuropathy in adolescents with type 1 diabetes using confirmatory tests known from adults and to identify risk factors and bedside methods for neuropathy. METHODS: Sixty adolescents with type 1 diabetes (diabetes duration > five years) and 23 control subjects underwent neurological examination and confirmatory diagnostic tests for neuropathy, including nerve conduction studies, skin biopsies determining intraepidermal nerve fiber density, quantitative sudomotor axon reflex test (QSART), cardiovascular reflex tests (CARTs), and tilt table test. Possible risk factors were analyzed. Bedside tests (biothesiometry, DPNCheck®, Sudoscan, and Vagus®device) were compared with the confirmatory tests using ROC analysis. RESULTS: The prevalence of neuropathies in the adolescents with diabetes (mean HbA1c 7.6% (60 mmol/mol)) was as follows: 14% confirmed/26% subclinical LFN, 2% confirmed/25% subclinical SFN, 20% abnormal QSART, 8% abnormal CARTs, and 14% orthostatic hypotension. Higher age, higher insulin dose, previous smoking, and higher triglycerides level were found to increase the relative risk for neuropathy. The bedside tests showed poor to acceptable concordance with the confirmatory tests (all, AUC ≤ 0.75). CONCLUSIONS: The diagnostic tests confirmed the presence of neuropathy in adolescents with diabetes and underscore the importance of prevention and screening.

Management of Diabetes during School Hours: A Cross-Sectional Questionnaire Study in Denmark.

Managing diabetes is complicated for many children. It often requires support from an adult during the school day. In Denmark, most children spend 30-35 h a week at school. Nevertheless, diabetes management in schools remains largely uninvestigated. This study aimed to examine the characteristics and organization of diabetes management in Danish primary schools from the personnel's perspective. All primary schools in Denmark were invited to participate in the study (n = 2129), and 525 schools were included. A questionnaire was constructed and sent by email. Questionnaire data are presented in the descriptive statistics and compared with the ISPAD guidelines. According to 77.2% of respondents, school personnel had received training in diabetes management, and 78.5% of the schools had at least one person available for diabetes support every day. Respondents felt prepared to help the students with counting carbohydrates (38.9%), dosing insulin (39.1%), and helping the students during high (52.1%) or low (60.3%) blood sugar levels, insulin chock (35.2%), or during activities (36.3%). Yet, diabetes management was a challenging task. Only 61.7% had an action plan for diabetes management, 37.4% had face-to-face information meetings with the parents, and 55.1% of respondents reported having sufficient time to cooperate with the parents.

Early Gastrointestinal Neuropathy Assessed by Wireless Motility Capsules in Adolescents with Type 1 Diabetes.

BACKGROUND: To assess the prevalence of objective signs of gastrointestinal (GI) autonomic neuropathy (AN) in adolescents with type 1 diabetes (T1D). In addition, to investigate associations between objective GI findings and self-reported symptoms or other findings of AN. METHODS: Fifty adolescents with T1D and 20 healthy adolescents were examined with a wireless motility capsule to assess the total and regional GI transit times and motility index. GI symptoms were evaluated with the GI Symptom Rating Scale questionnaire. AN was evaluated with cardiovascular and quantitative sudomotor axon reflex tests. RESULTS: There was no difference in GI transit times in adolescents with T1D and healthy controls. Adolescents with T1D had a higher colonic motility index and peak pressure than the controls, and GI symptoms were associated with low gastric and colonic motility index (all p < 0.05). Abnormal gastric motility was associated with the duration of T1D, while a low colonic motility index was inversely associated with "time in target range" for blood glucose (all p < 0.01). No associations were found between signs of GI neuropathy and other measures of AN. CONCLUSIONS: Objective signs of GI neuropathy are common in adolescents with T1D and it seems to require early interventions in patients at high risk of developing GI neuropathy.

Effect of a 10-week weight loss camp on fatty liver disease and insulin sensitivity in obese Danish children.

BACKGROUND AND OBJECTIVE: Childhood nonalcoholic fatty liver disease (NAFLD) associated with insulin resistance and obesity is a growing problem and increases the risk of cirrhosis, type 2 diabetes mellitus, and cardiovascular complications. We examined the effects of a 10-week "weight loss camp" residency in obese children on the prevalence and degree of NAFLD and insulin sensitivity with 12-month follow-up. METHODS: At the camp, 117 obese white children (body mass index 28.0 ±â€Š3.6  kg/m, age 12.1 ±â€Š1.3 years) exercised moderately for 1 hour/day and restricted their energy intake to induce weight loss. NAFLD was diagnosed and graded using ultrasound and transaminasemia. Insulin sensitivity and glucose tolerance were assessed using homeostasis model assessment and oral glucose tolerance test. We performed anthropometric measurements and determined body composition using bioimpedance. Data were collected from 71 of 117 children at entry, after the 10 weeks at the camp, and 12 months after the camp ended. RESULTS: The children showed an average weight loss of 7.1 ±â€Š2.7  kg during the camp. At baseline, 43% had ultrasonographic liver steatosis, 50% elevated transaminases (>25  IU/L), and reduced insulin sensitivity. These abnormalities were mutually related and improved significantly during the camp (P ≤ 0.05). Liver fat improvement was sustained at 12 months. At the 12-month follow-up, 17 of 71 (24%) children maintained the body weight. CONCLUSIONS: This short-term diet and exercise program induced weight loss, markedly improved all aspects of the threatening condition of NAFLD, and reduced insulin sensitivity in childhood obesity; 24% of the children maintained weight loss at least until the 12-month follow-up.
