RESUMO
Objective: Artificial intelligence-based decision support systems (DSS) need to provide decisions that are not inferior to those given by experts in the field. Recommended insulin dose adjustments on the same individual data set were compared among multinational physicians, and with recommendations made by automated Endo.Digital DSS (ED-DSS). Research Design and Methods: This was a noninterventional study surveying 20 physicians from multinational academic centers. The survey included 17 data cases of individuals with type 1 diabetes who are treated with multiple daily insulin injections. Participating physicians were asked to recommend insulin dose adjustments based on glucose and insulin data. Insulin dose adjustments recommendations were compared among physicians and with the automated ED-DSS. The primary endpoints were the percentage of comparison points for which there was agreement on the trend of insulin dose adjustments. Results: The proportion of agreement and disagreement in the direction of insulin dose adjustment among physicians was statistically noninferior to the proportion of agreement and disagreement observed between ED-DSS and physicians for basal rate, carbohydrate-to insulin ratio, and correction factor (P < 0.001 and P ≤ 0.004 for all three parameters for agreement and disagreement, respectively). The ED-DSS magnitude of insulin dose change was consistently lower than that proposed by the physicians. Conclusions: Recommendations for insulin dose adjustments made by automatization did not differ significantly from recommendations given by expert physicians regarding the direction of change. These results highlight the potential utilization of ED-DSS as a useful clinical tool to manage insulin titration and dose adjustments.

INTRODUCTION: The accuracy of blood pressure (BP) measurement is a prerequisite for the reliable diagnosis and management of hypertension. OBJECTIVES: This survey evaluated the use of office and out-of-office BP measurements and the antihypertensive pharmacological treatment in expert pediatric diabetes centers. METHODS: A questionnaire was distributed in 78 reference pediatric diabetes centers of the SWEET international consortium. The methodology, devices, indications, and interpretation of office BP measurements (OBPM), 24-hour ambulatory BP monitoring (ABPM) and home BP monitoring (HBPM), and the preference for antihypertensive drug treatment was assessed. A grading score was developed to evaluate centers for overall BP measurement performance. RESULTS: Fifty-two centers responded. The average score for OBPM methodology was 72.5%, for technology 77.5% and the overall center score was 74.75%.The majority of the centers used appropriate methodology and technology, however, there was heterogeneity among them. Manual auscultatory or automated devices specifically validated for children were used by 26/52 centers. ABPM was recommended by 35/52 centers (27/35 had health insurance coverage) and HBPM by 18/52 centers. The BP measurement methodology and devices used for ABPM and HBPM were frequently inadequate. Angiotensin converting enzyme inhibitors were the most frequently prescribed drugs for treating hypertension. CONCLUSIONS: The majority of SWEET pediatric diabetes centers use adequate methodology and devices for BP measurement. ABPM is recommended by two thirds of the centers, whereas HBPM is less widely used. Further improvement in the quality of office and out-of-office BP measurements and harmonization among centers is necessary according to current guidelines.

PURPOSE: To assess the efficacy of a real-time continuous glucose monitoring (RT-CGM) system added to insulin pump therapy for 3 months, in sub-optimally controlled adults with type 1 diabetes mellitus (T1D). METHODS: This was a prospective, multicenter, non-randomized, post-market release study. A total of 43 adult patients with T1D on insulin pump therapy and inadequate glycemic control (HbA1c > 7.0%) participated in the study. The primary endpoint was the change from baseline HbA1c levels. Secondary objectives were to evaluate the impact of the RT-CGM system on glucose variability, daily insulin requirements, and the frequency of hypoglycemic and ketoacidosis events. RESULTS: At 3 months, the baseline HbA1c values decreased from 8.0 (7.6, 8.7) to 7.1 (6.7, 8.0) % (p < 0.001). Nineteen participants (44.2%) had a posttreatment HbA1c level ≤ 7%. Average total daily insulin requirements, as well as the average number of insulin boluses per day, increased significantly after the use of the RT-CGM system. The number of hypoglycemic events recorded did not differ between the first week and last week of RT-CGM usage, while no severe hypoglycemic episodes, ketoacidosis events, or hospitalizations related to diabetes occurred during the 3-month follow-up period. CONCLUSION: Addition of a RT-CGM system to insulin pump therapy for 3 months in inadequately controlled patients with T1D resulted in improved HbA1c levels, without increasing the risk of hypoglycemic events.

The composition of the salivary proteome is affected by pathological conditions. We analyzed by high resolution mass spectrometry approaches saliva samples collected from children and adolescents with type 1 diabetes and healthy controls. The list of more than 2000 high confidence protein identifications constitutes a comprehensive characterization of the salivary proteome. Patients with good glycemic regulation and healthy individuals have comparable proteomic profiles. In contrast, a significant number of differentially expressed proteins were identified in the saliva of patients with poor glycemic regulation compared to patients with good glycemic control and healthy children. These proteins are involved in biological processes relevant to diabetic pathology such as endothelial damage and inflammation. Moreover, a putative preventive therapeutic approach was identified based on bioinformatic analysis of the deregulated salivary proteins. Thus, thorough characterization of saliva proteins in diabetic pediatric patients established a connection between molecular changes and disease pathology. This proteomic and bioinformatic approach highlights the potential of salivary diagnostics in diabetes pathology and opens the way for preventive treatment of the disease.
RESUMO
BACKGROUND: Although type 1 diabetes (T1D) remains the most frequent form of diabetes in individuals aged less than 20 years at onset, other forms of diabetes are being increasingly recognized. OBJECTIVES: To describe the population of children with other forms of diabetes (non-type 1) included in the multinational SWEET (Better control in Pediatric and Adolescent diabeteS: Working to crEate CEnTers of Reference) database for children with diabetes. METHODS: Cases entered in the SWEET database are identified by their physician as T1D, type 2 diabetes (T2D) and other types of diabetes according to the ISPAD classification. Etiologic subgroups are provided for other types of diabetes. Descriptive analyses were tabulated for age at onset, gender, daily insulin doses, and hemoglobin A1c (A1C) for each type and subtype of diabetes and when possible, values were compared. RESULTS: Of the 27â104 patients included in this report, 95.5% have T1D, 1.3% T2D, and 3.2% other forms of diabetes. The two most frequent etiologies for other forms of diabetes were maturity onset diabetes of the young (MODY) (n = 351) and cystic fibrosis-related diabetes (CFRD) (n = 193). The cause was unknown or unreported in 10% of other forms of diabetes. Compared with T1D, children with T2D and CFRD were diagnosed at an older age, took less insulin and had lower A1C (all P < .0001). CONCLUSION: In centers included in SWEET, forms of diabetes other than type 1 remain rare and at times difficult to characterize. Sharing clinical information and outcome between SWEET centers on those rare forms of diabetes has the potential to improve management and outcome.

Type 1 Diabetes Mellitus is a complex and polygenic disease due to gene-environment interactions. The role of genetic background of diabetes has been extensively investigated. However, final conclusions have not yet been reached. Family and twin studies have shown that genetic factors are important contributors to the genetic risk of the disease. Although more than 18 diabetes-predisposing genes have been reported to date, only the major histocompatibility complex (HLA) region on chromosome 6p21 (IDDM1) and the insulin gene on chromosome 11p15 (IDDM 2) have been conclusively associated with susceptibility to type 1 diabetes. However, it has been shown recently that cytotoxic lymphocyte antigen 4 (CTLA4) on chromosome 2q33 (IDDM12) and LYP/PTPN22 on chromosome 1p13 also contribute to the genetic risk of T1DM. The article reviews the recent advances in this field. By identifying new loci or reanalyzing the known ones and with the help of more powerful studies, it is possible in the future to be able to shed more light on the complex field of the genetics of type 1 diabetes and to further understand the pathophysiology of the disease, which will allow us eventually to treat or prevent it.

Type 1 diabetes mellitus (DM1) is caused by environmental factors acting on genetically susceptible individuals. HLA-DQA1 and -DQB1 are major genetic determinants of the disease. Greece and Albania represent the low DM1 incidence countries of South-Eastern Europe. The HLA-DQA1 and -DQB1 associations with DM1 were investigated in these two groups, as reference for comparisons to the high-risk populations of Northern Europe. One hundred and thirty Greeks and 64 Albanians with DM1 were studied; 1,842 Greeks and 186 Albanians were analysed as controls. The samples were typed for six HLA-DQB1 alleles, using time-resolved fluorometry to detect the hybridisation of lanthanide labelled oligonucleotides with PCR products. Individuals positive for DQB1*0201 were selectively typed for three DQA1 alleles. In both populations DQB1*0201 increased the risk for DM1 while DQB1*0301 was protective. DQB1*0302 was associated with lower risk than *0201, while *0602 and *0603 were protective in Greeks but not in Albanians. It was also shown that DQA1 has a modifying effect, altering the risk conferred by the susceptible DQB1*0201. The low incidence of DM1 in these two countries correlates with the high frequency of the protective allele DQB1*0301 and the low impact of the susceptible DQB1*0302.
