Accuracy of Two Continuous Glucose Monitoring Devices During Aerobic and High-Intensity Interval Training in Individuals with Type 1 Diabetes.

Background: This study aimed to evaluate the accuracy of Dexcom G6 (DG6) and FreeStyle Libre-2 (FSL2) during aerobic training and high-intensity interval training (HIIT) in individuals with type 1 diabetes. Methods: Twenty-six males (mean age 29.3 ± 6.3 years and mean duration of diabetes 14.9 ± 6.1 years) participated in this study. Interstitial glucose levels were measured using DG6 and FSL2, while plasma glucose levels were measured every 10 min using YSI 2500 as the reference for glucose measurements in this study. The measurements began 20 min before the start of exercise and continued for 20 min after exercise. Seven measurements were taken for each subject and exercise. Results: Both DG6 and FSL2 devices showed significant differences compared to YSI glucose data for both aerobic and HIIT exercises. Continuous glucose monitoring (CGM) devices exhibited superior performance during HIIT than aerobic training, with DG6 showing a mean absolute relative difference of 14.03% versus 31.98%, respectively. In the comparison between the two devices, FSL2 demonstrated significantly higher effectiveness in aerobic training, yet its performance was inferior to DG6 during HIIT. According to the 40/40 criteria, both sensors performed similarly, with marks over 93% for all ranges and both exercises, and above 99% for HIIT and in the >180 mg/dL range, which is in accordance with FDA guidelines. Conclusions: The findings suggest that the accuracy of DG6 and FSL2 deteriorates during and immediately after exercise but remains acceptable for both devices during HIIT. However, accuracy is compromised with DG6 during aerobic exercise. This study is the first to compare the accuracy of two CGMs, DG6, and FSL2, during two exercise modalities, using plasma glucose YSI measurements as the gold standard for comparisons. It was registered at clinicaltrials.gov (NCT06080542).

Comparison of GLP-1 receptor agonists and other Glucose-Lowering agents on cardiovascular outcomes in individuals with type 2 diabetes and Obesity: A Spanish Real-World Population-Based study.

AIMS: Assess the impact of glucagon-like peptide receptor agonists (GLP-1RA) compared to other glucose-lowering agents on cardiovascular outcomes in individuals with type 2 diabetes and obesity in a Spanish metropolitan area. METHODS: A retrospective population-based type 2 diabetes cohort was identified from the Valencia Clinic-Malvarrosa Department electronic databases (2014-2019). Study groups included GLP-1RA, sodium-glucose co-transporter-2 inhibitors (SGLT2i), Insulin, and Miscellany (other glucose-lowering agents). 1:1:1:1 propensity score matching was conducted. The primary outcome was a composite of major adverse cardiovascular events (4-point MACE) comprising myocardial infarction, stroke, all-cause mortality, and heart failure. Secondary outcomes included individual 4-point MACE components. Hazard ratios were estimated using Cox regression analyses against the Miscellany group. RESULTS: From 26,944 subjects, 1,848 adults were selected per group. GLP-1RA did not show a significant reduction in 4-point MACE risk (HR 1.05 [95%CI 0.82-1.34]). SGLT2i significantly reduced the risk of heart failure (HR 0.16 [95%CI 0.05-0.54]) and atrial fibrillation (HR 0.58, [95%CI 0.35-0.95]). The Insulin group exhibited a higher risk for 4-point MACE and most individual outcomes compared to GLP-1RA and SGLT2i. CONCLUSIONS: Our findings do not provide evidence of a reduced cardiovascular risk, as assessed by 4-point MACE, with GLP-1RA. In contrast, SGLT2i demonstrated protective effects against heart failure and atrial fibrillation.

Deterioro cognitivo tardío en pacientes con estenosis aórtica tratados con sustitución valvular quirúrgica y con implantación transcatéter de válvula aórtica: estudio comparativo / Delayed cognitive impairment in patients with aortic stenosis treated with surgical valve replacement and transcatheter aortic valve implantation: a comparative study

Introducción El deterioro cognitivo secundario a eventos cerebrovasculares es una complicación frecuente en las intervenciones de reemplazo de válvula aórtica. Nuestro objetivo es el estudio del perfil de deterioro de los pacientes sometidos a reemplazo valvular quirúrgico o implantación de prótesis transcatéter (TAVI) y si éste resulta diferente según la intervención a la que son sometidos y los factores de riesgo basales. Pacientes y métodos Estudio observacional prospectivo, con dos grupos no equivalentes de pacientes (grupo TAVI y grupo quirúrgico). Se realizaron comparaciones intergrupo en varios dominios cognitivos, con una evaluación basal y mediciones de seguimiento seis y 12 meses después la intervención. Resultados El grupo TAVI presentó resultados inferiores al grupo quirúrgico en funciones ejecutivas y visuoespaciales, puntuaciones parcialmente determinadas por la edad (p < 0,01) y el nivel intelectual previo (Pearson cociente intelectual previo-medias escalares en los test: 0,665; p < 0,001). La media de puntuaciones en los tres momentos de medición indica una disminución del rendimiento en funciones ejecutivas a los seis meses, que se recupera a los 12 meses. En memoria se registraron incrementos sostenidos en ambos momentos, en tanto que la función visuoespacial y la denominación no mostraron recuperación posterior de los niveles basales. Estas tendencias son similares en los dos grupos. Conclusión Los resultados obtenidos no confirman la instauración de un proceso específico de deterioro neurocognitivo postintervención en la estenosis aórtica complicada. El perfil de deterioro no presenta diferencias significativas entre los grupos, pero es más evidente en los pacientes con TAVI, debido a la influencia de las variables de selección de la muestra.

INTRODUCTION Cognitive impairment secondary to cerebrovascular events is a common complication of aortic valve replacement interventions. Our aim is to study the deterioration profile of patients who have undergone surgical valve replacement or transcatheter valve implantation (TAVI) and whether it differs according to the intervention they underwent and their baseline risk factors. PATIENTS AND METHODS We conducted a prospective observational study with two non-equivalent groups of patients (TAVI group and surgical group) Intergroup comparisons were carried out in several cognitive domains, with a baseline assessment and follow-up measurements six and 12 months after the intervention. RESULTS The TAVI group performed less well than the surgical group in executive and visuospatial functions, with scores partially determined by age (p < 0.01) and prior intellectual level (Pearson prior intelligence quotient-scalar test means: 0.665; p < 0.001). Mean scores at the three measurement points indicate a decline in executive function performance at six months, which is restored at 12 months. Sustained increases in memory were recorded at both time points, while visuospatial function and naming showed no subsequent recovery of the baseline levels. These trends are similar in both groups. CONCLUSION. The results obtained do not confirm the appearance of a specific process of post-intervention neurocognitive impairment in complicated aortic stenosis. The deterioration profile does not show any significant differences between groups, but is more evident in TAVI patients, due to the influence of variables related to sample selection. (AU)

Which people with diabetes are treated with a disposable, half-unit insulin pen? A real-world, retrospective, database study in Spain.

INTRODUCTION: Insulin lispro 100 units/mL Jr KwikPen is the first prefilled, disposable, half-unit insulin pen that delivers 0.5-30 units in increments of 0.5 units for the treatment of patients with diabetes. This study describes the profile of patients in Spain who initiated insulin therapy with Jr KwikPen in a real-world setting. METHODS: This retrospective, observational study based on IQVIA's electronic medical records database included patients with Type 1 (T1D) or Type 2 (T2D) diabetes who initiated therapy with Jr KwikPen between May 2018 and December 2020. Sociodemographic, clinical, and treatment characteristics at treatment initiation were analysed descriptively. RESULTS: A total of 416 patients were included. The main characteristics of the T1D/T2D groups (N = 326/90), respectively were as follows: female sex, 61.7%/65.6%; mean age (standard deviation [SD]), 32.5 (20.7)/55.5 (16.6) years; body mass index, 20.9 (4.2)/25.2 (4.6) kg/m2 (N = 239/77); HbA1c, 7.8 (1.7)%/8.0 (1.5)% (N = 141/64); and presence of diabetes-associated comorbidities, 27.9%/64.4%. Only 32.8% of patients with T1D were < 18 years old. Among Jr KwikPen users, 12.3% (T1D/T2D, 7.7%/28.9%) were ≥ 65 years old, 17.1% patients were newly diagnosed, and 3.8% were pregnant women. The mean (SD) total insulin dose pre-index for T1D/T2D was 43.1 (23.6) and 40.7 (21.6) UI/day, respectively. The mean (SD) insulin dose at the start of Jr KwikPen use was 26.63 (16.56) and 22.58 (13.59) UI/day for T1D/T2D, respectively. Jr KwikPen was first prescribed mainly by endocrinologists (58.7%) or paediatricians (22.6%). CONCLUSIONS: The profile of patients who initiated therapy with Jr KwikPen in routine practice was broad with many patients being adults. Most of these patients had T1D, inadequate glycemic control, and multiple associated comorbidities. These results suggest that Jr KwikPen is prescribed in patients who may benefit from finer insulin dose adjustments, namely children, adolescents, adults, older individuals, or pregnant women with T1D or T2D.

Validation of circulating microRNAs miR-142-3p and miR-598-3p in women with polycystic ovary syndrome as potential diagnostic markers.

STUDY QUESTION: Circulating miRNAs previously associated with androgen excess in women might be used as diagnostic biomarkers for polycystic ovary syndrome (PCOS). SUMMARY ANSWER: Models based on circulating miR-142-3p and miR-598-3p expression show good discrimination among women with and without PCOS, particularly when coupled with easily available measurements such as waist-to-hip ratio (WHR) and circulating LH-to-FSH (LH/FSH) ratios. WHAT IS KNOWN ALREADY: The lack of standardization of the signs, methods, and threshold values used to establish the presence of the diagnostic criteria (hyperandrogenism, ovulatory dysfunction, and polycystic ovarian morphology) complicates the diagnosis of PCOS. Certain biomarkers may help with such a diagnosis. We conducted a validation study to check the diagnostic accuracy for PCOS of several miRNAs that were associated with the syndrome in a small pilot study that had been previously carried out by our research group. STUDY DESIGN, SIZE, DURATION: This was a diagnostic test study involving 140 premenopausal women. PARTICIPANTS/MATERIALS, SETTING, METHODS: We included 71 women with PCOS and 69 healthy control women in the study. Both groups were selected as to be similar in terms of body mass index. We used miRCURY LNA™ Universal RT microRNA PCR to analyse the five miRNAs that had shown the strongest associations with PCOS in a much smaller pilot study previously conducted by our group. We studied diagnostic accuracy using receiver operating characteristics (ROC) curve analysis. MAIN RESULTS AND THE ROLE OF CHANCE: Only the expression of two miRNAs, miR-142-3p and miR-598-3p, of the five studied, was different between the women with PCOS and the non-hyperandrogenic controls. The diagnostic accuracy of the combination of these circulating miRNAs was good (area under the ROC curve (AUC) 0.801; 95% CI: 0.72-0.88) and was further improved when adding WHR (AUC 0.834, 95% CI: 0.756-0.912), LH/FSH ratio (AUC = 0.869, 95% CI: 0.804-0.934) or both (AUC = 0.895, 95% CI: 0.835-0.954). We developed several models by selecting different threshold values for these variables favouring either sensitivity or specificity, with positive and negative predictive values as high as 88% or 85%, respectively. LIMITATIONS, REASONS FOR CAUTION: Patients included here had the classic PCOS phenotype, consisting of hyperandrogenism and ovulatory dysfunction; hence, the present results might not apply to milder phenotypes lacking androgen excess. WIDER IMPLICATIONS OF THE FINDINGS: If confirmed in larger studies addressing different populations and PCOS phenotypes, these biomarkers may be useful to simplify the clinical diagnosis of this prevalent syndrome.

Real-World Evaluation of GLP-1 Receptor Agonist Therapy Persistence, Adherence and Therapeutic Inertia Among Obese Adults with Type 2 Diabetes.

INTRODUCTION: In type 2 diabetes (T2D), key barriers to optimal glycaemic control include lack of persistence with treatment, reduced medication adherence and therapeutic inertia. This study aimed to assess the impact of these barriers in obese adults with type 2 diabetes treated with a GLP-1 receptor agonist (GLP-1RA) and compare them against other glucose-lowering agents in a real-world setting. METHODS: A retrospective study was conducted using electronic medical records from 2014 to 2019 for adults with T2D at the Valencia Clínico-Malvarrosa Department of Health (Valencia, Spain). Four study groups were established: all GLP-1RA users, SGLT2i users, insulin users and other glucose-lowering agent users (miscellany group). To account for imbalance between groups, propensity score matching (PSM) including age, gender and pre-existing cardiovascular disease was performed. Chi-square tests were used for comparisons between groups. Time to first intensification was calculated using competing risk analysis. RESULTS: Among the 26,944 adults with T2D, 7392 individuals were selected following PSM, with 1848 patients in each group. At 2 years, GLP-1RA users were less persistent than non-users (48.4% versus 72.7%, p < 0.0001) but more adherent (73.8% versus 68.9%, respectively, p < 0.0001). A greater proportion of persistent GLP-1RA users than non-persistent users exhibited reduced HbA1c (40.5% versus 18.6%, respectively, p < 0.0001), but no differences in cardiovascular outcomes and death were found. Overall, therapeutic inertia was observed in 38.0% of the study population. The large majority of GLP-1RA users received treatment intensification, whereas only 50.0% of GLP-1RA non-users were intensified. CONCLUSION: Under real-life conditions, obese adults with T2D persistently treated with GLP-1RA showed improved glycaemic control. Despite benefits, persistence with GLP-1RA was limited after 2 years. Additionally, therapeutic inertia occurred in two out of three study participants. Strategies to facilitate medication adherence, persistence and treatment intensification in people with T2D should be made a priority in order to achieve and maintain glycaemic targets and improve outcomes in this population.

Impact of COVID-19 lockdown on diabetes management and follow-up in a broad population in Spain.

BACKGROUND: To evaluate the impact of COVID-19 lockdown on glycaemic control and diabetes follow-up in a Spanish metropolitan area with a total general population of 340,000. METHODS: A retrospective real-world study comparing HbA1c testing, an indicator of diabetes control, and mean HbA1c during different COVID-19 restriction periods in 2020 (full lockdown, post-lockdown, partial lockdown) with the same periods in 2019. HbA1c testing was analysed per study period and according to gender, age and clinical setting. Associations between HbA1c testing and different covariables were investigated using logistic regression analysis. Changes in HbA1c were evaluated by repeated measures multivariate analysis of variance (ANOVA). RESULTS: During full lockdown, 6847 individuals, of which 56.7% were over 65 and 6.5% below 40, were tested for HbA1c compared to 14,180 in 2019 (OR 0.47, 95% CI:0.46-0.49). Reduction in HbA1c testing was greater among older individuals (OR 0.44, 95% CI:0.42-0.45). No differences were observed for post-lockdown (OR 1.01, 95% CI:0.99-1.04). During partial lockdown, 10,816 individuals had at least one HbA1c measured compared to 12,749 in 2019 (OR 0.84, 95% CI:0.82-0.87). Mean HbA1c during full lockdown was 7.26% (±1.06) compared to 7.50% (±1.14) in 2019 (p < .0001). For gender and across all age groups, HbA1c levels were lower during full lockdown. HbA1c changes were not significantly different during post-lockdown and partial lockdown. CONCLUSIONS: COVID-19 restriction measures affected HbA1c testing. During complete lockdown, HbA1c testing decreased by half across all gender and age groups. No deleterious effect on glycaemic control was observed during lockdown and post-lockdown among those tested.

Real-world Evidence of Efficacy and Safety of SGLT2 Inhibitors as Adjunctive Therapy in Adults With Type 1 Diabetes: A European Two-Center Experience.

OBJECTIVE: To evaluate real-world efficacy and safety of sodium-glucose cotransporter 2 inhibitor (SGLT2i) use in combination with insulin in people with type 1 diabetes. RESEARCH DESIGN AND METHODS: We conducted a retrospective cohort European two-center study. Data on demographics, HbA1c, weight, insulin use, renal function, and adverse events were collected for 199 adults with type 1 diabetes who initiated a SGLT2i adjunct to insulin. Subgroup analyses were performed to identify who benefited most and who was more at risk for adverse events. RESULTS: Overall, significant reductions in mean HbA1c (-0.5%), weight (-2.9 kg), and daily insulin (-8.5%) were achieved after 12 months. The greatest reduction in HbA1c was obtained in individuals with baseline HbA1c >8% (-0.7% [64 mmol/mol]). The most weight loss was observed in subjects with BMI >27 kg/m2 (-3.5 kg). Individuals with baseline estimated glomerular filtration rate (eGFR) <90 mL/min/1.73 m2 showed an increase in eGFR (4.5 mL/min/1.73 m2), whereas those with urinary albumin-to-creatinine ratio (UACR) >15 mg/g showed a decrease in UACR (-16.6 mg/g). Fifty-seven individuals (28.6%) reported adverse events: 45 with genital infections (22.6%), 5 ketosis episodes (2.5%), and 7 diabetic ketoacidosis (DKA) (3.5%). No severe hypoglycemia events were reported. CONCLUSIONS: Our real-world data on SGLT2i showed promising results in reductions in HbA1c, weight, and insulin requirements in type 1 diabetes. Benefits were more pronounced in individuals with higher baseline HbA1c and BMI. DKA remained a major concern, despite educational measures. Further real-life evidence is still required for evaluation of SGLT2i longer-term effects and their impact on reno-cardiovascular outcomes.

Conversations and Reactions Around Severe Hypoglycaemia (CRASH): Spanish results of a global survey of people with type 1 diabetes or insulin-treated type 2 diabetes and caregivers.

INTRODUCTION: Information on experience/management of severe hypoglycaemic events (SHEs) among people with insulin-treated diabetes (PWD) and caregivers (CGs) providing care to PWD was sought. MATERIALS AND METHODS: An online cross-sectional survey was conducted in eight countries. INCLUSION CRITERIA: PWD (aged≥18 years; self-reported type 1 [T1D] or insulin-treated type 2 [T2D] diabetes; experienced ≥1 SHE [hypoglycaemia requiring external assistance] in past 3 years); CGs (layperson aged ≥18 years; caring for PWD meeting all criteria above except age [≥4 years]). This descriptive analysis provides data from Spain. SHE-associated data relate to the most recent SHE. RESULTS: Across all groups (T1D PWD, n=106; T2D PWD, n=88, T1D CG, n=87; T2D CG, n=96), 76-89% reported that the SHE occurred at home; most common cause was eating less than planned (38-53%). Most usual action during the SHE was to intake carbohydrates (67-84%); glucagon use was low (9-36%). Discussion of the SHE with their healthcare provider (HCP) was reported by 70-75% of PWD. During the SHE, 35-69% of PWD/CGs reported feeling scared, unprepared and/or helpless. CONCLUSIONS: Most SHEs occurred outside the healthcare setting; treatment therefore depends greatly on CGs. SHEs have a negative emotional impact on PWD/CGs, underscoring the need for HCPs to discuss SHEs with PWD/CGs, and to provide tools and strategies to prevent and effectively manage SHEs.

Enfermedad de Fabry y embarazo. Situación actual y revisión de la evidencia / Fabry's disease and pregnancy. Current situation and review of the evidence

En mujeres sintomáticas el embarazo empeora la enfermedad de Fabry, en un tercio de las asintomáticas aparecen entonces los síntomas. Hasta el momento, se han descrito 12 pacientes tratadas con terapia de reemplazo enzimático (TRE) durante el embarazo, sin evidencia de complicaciones asociadas o de compromiso fetal. Los altos niveles de LysoGB3 pueden implicar un mayor depósito de estos en la placenta e inducir un daño en sus vasos con el consiguiente riesgo de preeclampsia. Contrariamente a la práctica actual, la TRE no debe suprimirse. Se ha postulado el uso de hasta 2 mg/kg de peso galactosidasa-beta.(AU)

Pregnancy worsens the symptoms of Fabry's disease, and symptoms are developed in 1/3 of the asymptomatic women. So far, 12 patients treated with enzyme replacement therapy (ERT) during pregnancy have been described, with no evidence of associated complications or foetal compromise. The high levels of LysoGB3 may lead to a greater deposit of these in the placenta and induce vascular disease with the consequent risk of pre-eclampsia. Contrary to current practice, not only should ERT not be suppressed, but the use of up to 2 mg/kg of beta galactosidase weight is even postulated.(AU)

Patient-reported outcomes in adults with type 1 diabetes in global real-world clinical practice: The SAGE study.

AIMS: To conduct a secondary analysis of the SAGE study to evaluate the association between glycaemic control and patient-reported outcomes (PROs), in adults with type 1 diabetes (T1DM) across different age groups and regions. MATERIALS AND METHODS: SAGE was a multinational, cross-sectional, observational study in adults with T1DM. Data were collected at a single visit, analysed according to predefined age groups (26-44, 45-64, and ≥65 years), and reported across different regions. PRO questionnaires were applied to assess hypoglycaemia fear (Hypoglycemia Fear Survey-II), diabetes-related distress (Problem Areas In Diabetes questionnaire), insulin treatment satisfaction (Insulin Treatment Satisfaction Questionnaire), and diabetes-specific quality of life (QoL; Audit of Diabetes-Dependent Quality of Life). Multivariable analysis was performed to evaluate the relationship between glycated haemoglobin (HbA1c) target achievement (<7% and individualised targets) with PRO scores. RESULTS: The PRO scores showed relatively low levels of diabetes-related emotional distress and fear of hypoglycaemia, moderate to high treatment satisfaction, and low diabetes-related impact on QoL. Results were generally comparable across age groups with some regional variability. Achievement of the HbA1c <7% target was associated with less worry about hypoglycaemia, lower diabetes-related emotional distress, higher insulin treatment satisfaction, and higher QoL. Achievement of individualised HbA1c targets was associated with lower diabetes-related emotional distress and higher insulin treatment satisfaction. CONCLUSIONS: Better glycaemic control was most closely associated with low emotional distress due to diabetes and high patient-reported insulin treatment satisfaction.

Therapeutic inertia in patients with type 2 diabetes treated with non-insulin agents.

AIMS: To analyze therapeutic inertia in type 2 diabetes (T2D) subjects with suboptimal glycemic control and treated with ≥2 non-insulin antidiabetic agents in a primary care setting. METHODS: A retrospective study was conducted using electronic medical records from subjects with HbA1c ≥7.0% (≥53 mmol/mol). Therapeutic inertia was defined as the absence of treatment intensification despite suboptimal glycemic control where intensification should have been implemented (HbA1c ≥7.5% [≥58 mmol/mol]). Time to the first intensification with non-insulin antidiabetic agent or insulin and HbA1c values at the time of intensification were evaluated by competing risk analysis. RESULTS: 2652 adults with T2D and HbA1c ≥7.0% (≥53 mmol/mol) were included. During the 4-year follow-up, among 1628 individuals with HbA1c ≥7.5% [≥58 mmol/mol], therapeutic inertia was present in 42.9% of cases. Median time to intensification was 14.5 months (IQR25-75, 4-24 months). In this subgroup, 72.7% of subjects initiated non-insulin agents whereas 27.3% initiated insulin. Mean HbA1c values at initiation of treatment intensification were 8.6% (70 mmol/mol) and 9.2% (77 mmol/mol), respectively. CONCLUSIONS: Therapeutic inertia occurred in over 40% of subjects. Treatment intensification took longer and was performed at higher HbA1c than recommended in clinical guidelines. Reducing therapeutic inertia is a priority to achieve therapeutic goals and prevent chronic complications in T2D.

Update on postprandial hyperglycaemia: the pathophysiology, prevalence, consequences and implications of treating diabetes. / Actualización sobre hiperglucemia posprandial: fisiopatología, prevalencia, consecuencias e implicaciones para el tratamiento de la diabetes.

To achieve appropriate glycaemic control, postprandial and baseline hyperglycaemia should be reduced. Various epidemiological studies have suggested an association between fluctuations in postprandial blood glucose and cardiovascular risk. However, studies of interventions performed to date have not shown that selective control of postprandial hyperglycaemia is associated with cardiovascular benefits. Accordingly, an appropriate combination of drugs that control both baseline and postprandial hyperglycaemia (individually based on each patient's characteristics) is the best strategy for achieving good glycaemic control. This review seeks to impart to clinicians the concept of postprandial hyperglycaemia, analysing its causes, how to measure it, its prevalence, its consequences and, ultimately, the available therapeutic strategies for the preferential control of the postprandial hyperglycaemia along with baseline hyperglycaemia.

How often patients on insulin therapy measure postprandial glycemia and modify insulin doses accordingly? From an on-line survey in insulin-treated diabetes patients in Spain.

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 ±â€¯13 years [mean ±â€¯SD], body mass index (BMI) 24.2 ±â€¯4.2 kg/m2, diabetes duration 17.4 ±â€¯12.8 years, insulin dose 38 ±â€¯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.

International Consensus on Risk Management of Diabetic Ketoacidosis in Patients With Type 1 Diabetes Treated With Sodium-Glucose Cotransporter (SGLT) Inhibitors.

Sodium-glucose cotransporter (SGLT) inhibitors are new oral antidiabetes medications shown to effectively reduce glycated hemoglobin (A1C) and glycemic variability, blood pressure, and body weight without intrinsic properties to cause hypoglycemia in people with type 1 diabetes. However, recent studies, particularly in individuals with type 1 diabetes, have demonstrated increases in the absolute risk of diabetic ketoacidosis (DKA). Some cases presented with near-normal blood glucose levels or mild hyperglycemia, complicating the recognition/diagnosis of DKA and potentially delaying treatment. Several SGLT inhibitors are currently under review by the U.S. Food and Drug Administration and European regulatory agencies as adjuncts to insulin therapy in people with type 1 diabetes. Strategies must be developed and disseminated to the medical community to mitigate the associated DKA risk. This Consensus Report reviews current data regarding SGLT inhibitor use and provides recommendations to enhance the safety of SGLT inhibitors in people with type 1 diabetes.

Propensity-score-matched comparative analyses of simultaneously administered fixed-ratio insulin glargine 100 U and lixisenatide (iGlarLixi) vs sequential administration of insulin glargine and lixisenatide in uncontrolled type 2 diabetes.

AIM: To conduct two exploratory analyses to compare indirectly the efficacy and safety of simultaneous administration of insulin glargine 100 U (iGlar) and the glucagon-like peptide-1 receptor agonist (GLP-1RA) lixisenatide (Lixi) as a single-pen, titratable, fixed-ratio combination (iGlarLixi [LixiLan trials]) vs sequential administration of iGlar + Lixi (GetGoal Duo trials) in people with type 2 diabetes (T2D). MATERIALS AND METHODS: Propensity-score matching based on baseline covariates was used to compare simultaneous iGlarLixi vs sequential combination of iGlar + Lixi with the addition of Lixi in patients who did not reach the glycated haemoglobin (HbA1c) goal of <53 mmol/mol (<7%) after short-term use of iGlar alone (LixiLan-O vs GetGoal Duo-1 comparison) and vs sequential addition of Lixi in uncontrolled patients after long-term use of iGlar alone (LixiLan-L vs GetGoal Duo-2 comparison). RESULTS: In both analyses, compared with sequential iGlar + Lixi, iGlarLixi led to significantly greater HbA1c reductions with associated weight loss and significantly more patients reaching target HbA1c <53 mmol/mol despite lower insulin doses. Symptomatic hypoglycaemia rates were similar, despite greater HbA1c reductions with iGlarLixi. Lower rates of gastrointestinal adverse events were observed with iGlarLixi, probably as a result of the more gradual titration of Lixi with iGlarLixi. CONCLUSIONS: Indirect propensity-score-matched exploratory comparisons suggest that early treatment with a simultaneous, titratable, fixed-ratio combination of basal insulin and a GLP-1RA (iGlarLixi) may be more effective and possess better gastrointestinal tolerability than a sequential approach of adding a GLP-1RA in patients with uncontrolled T2D initiating or intensifying basal insulin therapy.

Glycaemic control and hypoglycaemia in people with type 2 diabetes switching from twice-daily basal insulin to once-daily insulin glargine 300 U/mL or insulin glargine 100 U/mL (EDITION 1 and EDITION 2 subgroup analysis).

In this post hoc analysis we compared glycaemic control and hypoglycaemia between insulin glargine 300 U/mL (Gla-300) and glargine 100 U/mL (Gla-100) administered once daily in people with type 2 diabetes (T2DM) from the EDITION 1 (basal plus mealtime insulin) and EDITION 2 (basal insulin plus oral antihyperglycaemic drugs) trials who were previously receiving twice-daily insulin. At randomization, 16.9% and 20.0% of people in EDITION 1 and 2, respectively, were receiving twice-daily basal insulin. Glycated haemoglobin change from baseline to Month 6 was similar over 6 months with Gla-300 or Gla-100 (least squares mean difference -0.01%; 95% confidence interval [CI] -0.27 to 0.24] in EDITION 1 and 0.16%; 95% CI -0.25 to 0.57, in EDITION 2). Participants previously receiving twice-daily insulin in EDITION 1 had a lower risk of confirmed (≤3.9 mmol/L [≤70 mg/dL]) or severe hypoglycaemia with Gla-300 vs Gla-100 at night (00:00-05:59 hours), but not at any time (24 hours); in EDITION 2 the risk was reduced at night and any time (24 hours). In conclusion, Gla-300 provided similar glycaemic control with less hypoglycaemia compared with Gla-100 in people with T2DM switching from twice-daily to once-daily basal insulin.

Risk and impact of herpes zoster on patients with diabetes: A population-based study, 2009-2014.

AIMS: This study was designed to assess the impact of diabetes on the risk and severity of herpes zoster (HZ), and the impact of HZ on diabetes. It focused primarily on immunocompetent patients aged ≥ 50 years who would be eligible for preventive vaccination. METHODS: Using population and healthcare databases of Valencia Region (Spain), a retrospective cohort of all subjects ≥ 50 years was followed up between 2009 and 2014. HZ and diabetes were defined using ICD-9 codes. We compared the incidence of HZ between non-diabetes and diabetes groups and healthcare resource consumption due to HZ in the 6 months following HZ diagnosis using different statistical generalized linear models (GLM). We also compared resources consumption due to diabetes treatment and haemoglobinA1c(HbA1c) levels before and after HZ. RESULTS: The cohort consisted of 2,289,485 individuals ≥ 50 years old, 397,940 of whom had diabetes. HZ incidence rate was 9.3 cases/1000 persons with diabetes-year (95% CI: 9.1-9.4). Incidence increased with age in all groups. The risk of HZ increased in the diabetes group compared to the non-diabetes group (RR 1.2, 95% credibility interval [CrI] 1.17-1.22). Patients with diabetes utilized more health care resources due to their HZ episodes than patients without diabetes. In 24% of well controlled patients with diabetes (HbA1C levels ≤ 6.5%), HbA1C increased after HZ. CONCLUSIONS: Diabetes increased by 20% the risk of HZ. HZ contributed to the deterioration of glycaemic control and higher healthcare resource consumption in people with diabetes, becoming a priority population for HZ immunization.

Extensive Assessment of Blood Glucose Monitoring During Postprandial Period and Its Impact on Closed-Loop Performance.

BACKGROUND: Closed-loop (CL) systems aims to outperform usual treatments in blood glucose control and continuous glucose monitors (CGM) are a key component in such systems. Meals represents one of the main disturbances in blood glucose control, and postprandial period (PP) is a challenging situation for both CL system and CGM accuracy. METHODS: We performed an extensive analysis of sensor's performance by numerical accuracy and precision during PP, as well as its influence in blood glucose control under CL therapy. RESULTS: During PP the mean absolute relative difference (MARD) for both sensors presented lower accuracy in the hypoglycemic range (19.4 ± 12.8%) than in other ranges (12.2 ± 8.6% in euglycemic range and 9.3 ± 9.3% in hyperglycemic range). The overall MARD was 12.1 ± 8.2%. We have also observed lower MARD for rates of change between 0 and 2 mg/dl. In CL therapy, the 10 trials with the best sensor spent less time in hypoglycemia (PG < 70 mg/dl) than the 10 trials with the worst sensors (2 ± 7 minutes vs 32 ± 38 minutes, respectively). CONCLUSIONS: In terms of accuracy, our results resemble to previously reported. Furthermore, our results showed that sensors with the lowest MARD spent less time in hypoglycemic range, indicating that the performance of CL algorithm to control PP was related to sensor accuracy.
