Background: Our objective was to assess the effect of a hybrid telemedicine approach, in conjunction with face-to-face follow-up, on the quality of life in recent users of an advanced hybrid closed-loop (AHCL) system., Methods: A 1-year open randomized (1:1) clinical trial (ClinicalTrials.gov ID NCT04900636). Participants with type 1 diabetes (T1D) recent users of an AHCL system (Minimed ® 780G) for at least 2-6 months, and ⩾18 years old were eligible. The primary outcome was the change in quality of life measured by the Type 1 Diabetes Life (ViDa1) Questionnaire from baseline to 12 months of hybrid telemedicine plus face-to-face follow-up compared to standard clinical practice. Additionally, impacts on A 1c levels, glucose metrics, advert events, and safety outcomes were assessed., Results: Between January and December 2021, 46 participants were randomly assigned in a 1:1 ratio to either the hybrid telemedicine group ( n  = 23) or the control group ( n  = 23); 45 participants completed the study, with only 1 from the control group withdrawing before visit 3. At baseline, mean age was 37 ± 15 years and A 1c was 6.9 ± 0.5%. After 12 months, no statistically significant differences in ViDa1 scores between groups were observed. Despite reducing in-person visits in the hybrid follow-up arm, there were no increases in adverse events. Overall, A 1c levels significantly decreased from 6.9 ± 0.5% at baseline to 6.7 ± 0.5% after 12 months ( P  = 0.006) without differences between treatment arms, accompanied by reductions in glycemic variability and time below the target range., Conclusion: Our study suggests that there were no significant differences in ViDa1 scores between the two groups at the end of the follow-up. However, among adult patients with T1D who recently adopted an AHCL system, satisfactory glycemic control can be attained through a hybrid follow-up approach, reducing face-to-face visits, without increasing technical complications., (© The Author(s), 2024.)

Aims: To evaluate the efficacy of an advance closed-loop (AHCL) system in restoring awareness of hypoglycemia in patients with type 1 diabetes (T1D)., Methods: We conducted a prospective study including 46 subjects with T1D flash glucose monitoring (FGM) or continuous glucose monitoring (CGM) switching to a Minimed 780G® system. Patients were classified in three groups according to the therapy used before switching to Minimed® 780G: multiple dose insulin (MDI) therapy + FGM (n = 6), continuous subcutaneous insulin infusion + FGM (n = 21), and sensor-augmented pump with predictive low-glucose suspend (n = 19). FGM/CGM data were analyzed at baseline, after 2 and 6 months on AHCL. Clarke's score of hypoglycemia awareness was compared at baseline and 6 months recordings. We also compared the efficacy of the AHCL system in improving A 1c among patients with appropriate perception of symptoms of hypoglycemia compared to those presenting with impaired awareness of hypoglycemia (IAH)., Results: Participants had a mean age of 37 ± 15 and a diabetes duration of 20 ± 10 years. At baseline, 12 patients (27%) showed IAH as defined by a Clarke's score ≥ 3. Patients with IAH were older and had lower estimated glomerular filtration rate (eGFR) compared with those who did not have IAH; with no differences in baseline CGM metrics or A 1c . An overall decrease in A 1c was observed after 6 months on AHCL system (from 6.9 ± 0.5% to 6.7 ± 0.6%, P < 0.001), regardless of prior insulin therapy. The improvement in metabolic control was greater in patients with IAH, showing a reduction in A 1c from 6.9 ± 0.5 to 6.4 ± 0.4% vs 6.9 ± 0.5 to 6.8 ± 0.6% (P = 0.003), showing a parallel increase in total daily boluses of insulin and automatic bolus correction administered by the AHCL system. In patients with IAH Clarke's score decreased from 3.6 ± 0.8 at baseline to 1.9 ± 1.6 after 6 months (P < 0.001). After 6 months on AHCL system, only 3 patients (7%) presented with a Clarke's score ≥ 3, resulting in an absolute risk reduction of 20% (95% confidence interval: 7-32) of having IAH., Conclusions: Switching from any type of insulin administration to AHCL system improves restoration of hypoglycemia awareness and metabolic control in patients with T1D, particularly in adults with impaired perception of hypoglycemia symptoms., Trial Registration: ClinicalTrial.gov ID NCT04900636., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier B.V.

Objectives: The Clarke questionnaire, validated in Spanish language, assesses hypoglycemia awareness in patients with type 1 diabetes. This study aimed to analyze its psychometric properties in patients with type 2 diabetes (T2DM)., Methods: This was a questionnaire validation study. Patients with T2DM and treated with insulin, sulfonylureas or glinides were consecutively recruited from six endocrinology consultations and six primary care centers. The internal structure of the 8-item Clarke questionnaire was analyzed by exploratory (training sample) and confirmatory (testing sample) factor analysis; the internal consistency using Omega's McDonald coefficient; and goodness of fit with comparative fit index (CFI, cutoff >0.9), Goodness of Fit Index (GFI, cutoff >0.9), and root mean-square error of approximation (RMSEA, cutoff <0.09), as well as unidimensionality indicators., Results: The 265 participants (56.8% men) had a mean age of 67.8 years. Confirmatory factor analysis for one dimension obtained poor indicators: fit test (p < 0.001); CFI = 0.748; RMSEA = 0.122 and SRMR = 0.134. Exploratory factor analysis showed 2 or 3 dimensions with poor adjustment indicators. Omega's McDonald was 0.739., Conclusions: The Spanish version of the Clarke questionnaire was not valid or reliable for assessing hypoglycemia awareness in people with T2DM in Spanish population.

Introduction: Controlling postprandial glycemia (PPG) is important to achieve optimal glycemic control, but few studies have evaluated how often is measured and evaluated., Objectives: To evaluate how often patients on insulin therapy measure PPG and modify insulin doses accordantly. As secondary objectives, we evaluated the factors conditioning elevated PPG and associated issues., Material and Methods: Cross-sectional observational study based on a web-based survey from an unselected sample of adult insulin-treated patients. A p-value of < 0.05 was significant., Results: 1251 patients (68% women, 38.9 ± 13 years [mean ± SD], body mass index (BMI) 24.2 ± 4.2 kg/m 2 , diabetes duration 17.4 ± 12.8 years, insulin dose 38 ± 18 IU) participated, 1104 with autoinmmune disease (AD) and 147 with non-autoinmmune diabetes (NAD). 59% of patients had HbA1c ≤ 7%, 92.7% of patients with AD and 55.8% with NAD were attended by specialists (p < 0.001). People with AD did more often blood glucose monitoring (BGM) (p < 0.0001) and used continuous glucose monitoring systems (CGMS) (p < 0.0001). 90.1% with AD and 68.0% with NAD received instructions on measuring PPG (p < 0.001), and more with AD received specific training to change the treatment (87% vs. 61.2%, p < 0.0001) and were more proactive. However, more with NAD discussed their postprandial glucose levels with their healthcare team during clinical visits (92.5% vs. 74.1%, p < 0.0001). Regarding bolus administration, 88.6% with AD and 68.7% with NAD injected the insulin bolus before meals (p < 0.001)., Conclusions: Patients with AD determine PPG more frequently. Diabetes type, follow-up setting, number of injections and CGMS use were the most important predictive factors for PPG measurement. Diabetes education programs should address how to best monitor PPG and appropriate corrective actions., (Copyright © 2019 Elsevier B.V. All rights reserved.)

Objective: To report the clinical characteristics of patients with latent autoimmune diabetes in adults (LADA), and to ascertain their metabolic control and associated chronic complications., Methods: Patients with DM attending specialized medical care in Madrid who met the following criteria: age at diagnosis of DM >30years, initial insulin independence for at least 6months and positive GAD antibodies were enrolled. Clinical profiles, data on LADA diagnosis, associated autoimmunity, C-peptide levels, therapeutic regimen, metabolic control, and presence of chronic complications were analyzed., Results: Number of patients; 193; 56% females. Family history of DM: 62%. Age at DM diagnosis: 49years. Delay in confirmation of LADA: 3.5years. Insulin-independence time: 12months. Baseline serum C-peptide levels: 0.66ng/ml. Basal-bolus regimen: 76.7%. Total daily dose: 35.1U/day, corresponding to 0.51U/Kg. With no associated oral antidiabetic drugs: 33.5%. Other autoimmune diseases: 57%. Fasting plasma glucose: 160.5mg/dL. HbA1c: 7.7%. BMI: 25.4kg/m 2 (overweight, 31.5%; obesity, 8%). Blood pressure: 128/75. HDL cholesterol: 65mg/dL. LDL cholesterol: 96mg/dL. Triglycerides: 89mg/dL. Known chronic complications: 28%., Conclusions: Recognition of LADA may be delayed by several years. There is a heterogeneous pancreatic insulin reserve which is negative related to glycemic parameters. Most patients are poorly controlled despite intensive insulin therapy. They often have overweight, but have adequate control of BP and lipid profile and a low incidence of macrovascular complications., (Copyright © 2016 SEEN. Publicado por Elsevier España, S.L.U.

Aproximately 5-10% of neuroendocrine tumours (NETs) of the gastroenteropancreatic system (GEP) have an hereditary background. The known hereditary syndromes include: multiple endocrine neoplasia type 1 (MEN 1), von Hippel Lindau disease (VHL), neurofibromatosis type 1 (NF 1) and tuberous sclerosis complex (TSC). This review discusses for each of these syndromes the: genes involved and specifics types of mutations, disease prevalence, affected neuroendocrine tissues and related clinical syndromes, and special morphological features of NETs on each of these syndromes.

Sufficient evidence exists in relation to the association in clinical practice between disorders in the metabolism of glucose, lipoproteins, insulin action, arterial hypertension and centrally-distributed obesity. This association is named Metabolic Syndrome. Despite the existence thereof had been questioned by the ADA and EASD, it is a useful tool affording the possibility of identifying individuals at high risk of developing cardiovascular disease. Metabolic syndrome and/or its individual components are associated with a high incidence rate of cardiovascular disease. Obesity and a sedentary lifestyle are underlying risk factors along this syndrome's pathway to disease, changes in living habits therefore being a first-line intervention in the prevention and treatment of insulin resistance, hyperglycemia, aterogenic dyslipemia and arterial hypertension. Weight loss and exercise are the keys to the overall plan, one of the most important non-pharmacological cardiovascular risk reduction strategies however still being diet. Epidemiological studies have found a high intake of simple sugars, of foods having a glycemic index and of diets with a high glycemic load to be associated to insulin resistance, type II diabetes mellitus, hypertriglyceridemia and low HDL-cholesterol figures. Los saturated fat intake in favor of polyunsaturated and monounsaturated fatty acids has been implied in a reduction of the incidence of type II diabetes mellitus and dyslipemia, although the debate is ongoing. Unrefined grain fiber in the diet has been beneficial in reducing the risk of diabetes. Among the diet patterns, the Mediterranean diet has been related to a lower incidence of diabetes and a reduction in the risk of death. Studies for intervention in the prevention of type II diabetes have suggested low-fat diets (reducing saturated and trans-fats), with a high degree of fiber and low glycemic index. Clinical trials have shown diets with small amounts of carbohydrates, low glycemic index and the Mediterranean and DASH diets to be beneficial in reducing aterogenic dyslipemia. There is currently no good evidence for choosing diets with restricted carbohydrates. On the other hand, different guides recommend low-calorie diets with a low content in saturated fats, trans-fats, cholesterol and sugars in favor the eating fruits, green vegetables, unrefined grains and fish.
