RESUMO
AIMS/HYPOTHESIS: Our study aims to uncover glycaemic phenotype heterogeneity in type 1 diabetes. METHODS: In the Study of the French-speaking Society of Type 1 Diabetes (SFDT1), we characterised glycaemic heterogeneity thanks to a set of complementary metrics: HbA1c, time in range (TIR), time below range (TBR), CV, Gold score and glycaemia risk index (GRI). Applying the Discriminative Dimensionality Reduction with Trees (DDRTree) algorithm, we created a phenotypic tree, i.e. a 2D visual mapping. We also carried out a clustering analysis for comparison. RESULTS: We included 618 participants with type 1 diabetes (52.9% men, mean age 40.6 years [SD 14.1]). Our phenotypic tree identified seven glycaemic phenotypes. The 2D phenotypic tree comprised a main branch in the proximal region and glycaemic phenotypes in the distal areas. Dimension 1, the horizontal dimension, was positively associated with GRI (coefficient [95% CI]) (0.54 [0.52, 0.57]), HbA1c (0.39 [0.35, 0.42]), CV (0.24 [0.19, 0.28]) and TBR (0.11 [0.06, 0.15]), and negatively with TIR (-0.52 [-0.54, -0.49]). The vertical dimension was positively associated with TBR (0.41 [0.38, 0.44]), CV (0.40 [0.37, 0.43]), TIR (0.16 [0.12, 0.20]), Gold score (0.10 [0.06, 0.15]) and GRI (0.06 [0.02, 0.11]), and negatively with HbA1c (-0.21 [-0.25, -0.17]). Notably, socioeconomic factors, cardiovascular risk indicators, retinopathy and treatment strategy were significant determinants of glycaemic phenotype diversity. The phenotypic tree enabled more granularity than traditional clustering in revealing clinically relevant subgroups of people with type 1 diabetes. CONCLUSIONS/INTERPRETATION: Our study advances the current understanding of the complex glycaemic profile in people with type 1 diabetes and suggests that strategies based on isolated glycaemic metrics might not capture the complexity of the glycaemic phenotypes in real life. Relying on these phenotypes could improve patient stratification in type 1 diabetes care and personalise disease management.
RESUMO
BACKGROUND: Myocardial infarction (MI), stroke, peripheral arterial disease (PAD), heart failure (HF) and chronic kidney disease (CKD) are common cardiovascular renal diseases (CVRD) manifestations for type 2 diabetes. The objective was to estimate the incidence of the first occurring CVRD manifestation and cumulative hospitalization costs of each CVRD manifestation for type 2 diabetes without CVRD history. METHODS: A cohort study of all type 2 diabetes free of CVRD as of January 1st 2014, was identified and followed-up for 5 years within the French SNDS nationwide claims database. The cumulative incidence of the first occurring CVRD manifestation was estimated using the cumulative incidence function, with death as a competing risk. Cumulative hospitalization costs of each CVRD manifestations were estimated from the perspective of all payers. RESULTS: From 2,079,089 type 2 diabetes without cancer or transplantation, 76.5% were free of CVRD at baseline with a mean age of 65 years, 52% of women and 7% with microvascular complications history. The cumulative incidence of a first CVRD manifestation was 15.3% after 5 years of follow-up with a constant linear increase over time for all CVRD manifestations: The most frequent was CKD representing 40.6% of first occurred CVRD manifestation, followed by HF (23.0%), then PAD (13.5%), stroke (13.2%) and MI (9.7%). HF and CKD together reached about one patient out of ten after 5 years and represented 63.6% of first CVRD manifestations. The 5-year global cost of all CVRD hospitalizations was 3.9 billion euros (B), i.e. 2,450 per patient of the whole cohort, with an exponential increase over time for each specific CVRD manifestation. The costliest was CKD (2.0 B), followed by HF (1.2 B), then PAD (0.7 B), stroke (0.6 B) and MI (0.3 B). CONCLUSIONS/INTERPRETATION: While MI, stroke and PAD remain classic major risks of complications for CVRD-free type 2 diabetes, HF and CKD nowadays represent individually a higher risk and cost than each of these classic manifestations, and jointly represents a risk and a cost twice as high as these three classic manifestations all together. This should encourage the development of specific HF and CKD preventive strategies.

Postprandial hyperglycaemia (PPH) may sometimes be relegated to the background in the treatment of diabetic patients, while its control seems important if not essential to reach an adequate overall glycaemic control. PPH is correlated with glycated haemoglobin and diabetic complications. It is also identified as a cardiovascular risk factor. PPH's monitoring and adequate control are not only a therapeutic goal for diabetes itself but also for reducing associated adverse outcomes other than diabetic complications. PPH is related to the quality of life of patients. Continuous glucose monitoring allows a better appraisal of PPH. The use of new insulin formulations as ultra-fast insulins seems to be the better way to manage post-prandial blood glucose peaks.
L'hyperglycémie postprandiale (HGPP) peut parfois passer au second plan lors de la prise en charge globale du patient diabétique. Néanmoins, sa maîtrise est indispensable pour obtenir un équilibre glycémique global optimal. L'HGPP est corrélée à l'hémoglobine glyquée ainsi qu'aux complications du diabète. Elle semble également jouer un rôle par rapport au risque cardiovasculaire. Outre son intérêt dans la prise en charge thérapeutique du diabète proprement dit, l'HGPP doit être maîtrisée en raison de son lien avec d'autres conséquences médicales et de son impact négatif sur la qualité de vie des patients. Le monitoring continu du glucose permet une meilleure appréciation de l'HGPP. Les nouvelles insulines ultra-rapides paraissent être les molécules les plus adéquates pour réduire, au mieux et au plus vite, l'HGPP.

AIM: To assess the safety and efficacy of the short-acting glucagon-like peptide-1 receptor agonist exenatide on a population of patients with type 2 diabetes (T2D) mostly treated with continuous subcutaneous insulin injection (CSII). MATERIALS AND METHODS: A phase 2/3, multicentre, randomized, parallel-group, double-blind, placebo-controlled, 6-month trial was conducted. Patients were randomized to receive subcutaneous (SC) injections of exenatide (10 µg BID) or matched placebo. RESULTS: A total of 46 patients with T2D and elevated HbA1c were randomized (42% of the planned sample size): exenatide (n = 28) and placebo (n = 18). CSII treatment was used by 75% and 89% of patients of the exenatide and placebo groups, respectively. At 6 months, the change in HbA1c was -0.62% ± 0.94% and 0.08% ± 0.81% in the exenatide and placebo groups, respectively (difference, -0.70%; 95% CI [-1.24%; -0.15%], P = .014); body weight and body mass index decreased in the exenatide group (-2.55 ± 3.25 kg and -1.00 ± 1.31 kg/m2 ) and increased in the placebo group (1.29 ± 2.82 kg and 0.46 ± 1.16 kg/m2 ) (observed difference, -3.85 and -1.45, respectively, both P < .001); the postdinner capillary blood glucose value was lower in the exenatide group compared with the placebo group (162.4 ± 80.5 vs. 259.1 ± 94.4 mg/dL, respectively; observed difference, -96.7, P < .01). Hypoglycaemic risk, quality of life and overall safety were not different between the groups, apart from the expected occurrence of digestive effects in the exenatide group. CONCLUSIONS: Although we failed to reach our planned sample size, the addition of exenatide treatment 10 µg BID SC in T2D patients with uncontrolled HbA1c despite an intensified insulin regimen, resulted in a significant reduction of HbA1c and body weight with a good overall safety profile and acceptance.

RESUMO
AIMS/HYPOTHESIS: Coronavirus disease-2019 (COVID-19) is a life-threatening infection caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) virus. Diabetes has rapidly emerged as a major comorbidity for COVID-19 severity. However, the phenotypic characteristics of diabetes in COVID-19 patients are unknown. METHODS: We conducted a nationwide multicentre observational study in people with diabetes hospitalised for COVID-19 in 53 French centres in the period 10-31 March 2020. The primary outcome combined tracheal intubation for mechanical ventilation and/or death within 7 days of admission. Age- and sex-adjusted multivariable logistic regressions were performed to assess the prognostic value of clinical and biological features with the endpoint. ORs are reported for a 1 SD increase after standardisation. RESULTS: The current analysis focused on 1317 participants: 64.9% men, mean age 69.8 ± 13.0 years, median BMI 28.4 (25th-75th percentile: 25.0-32.7) kg/m2; with a predominance of type 2 diabetes (88.5%). Microvascular and macrovascular diabetic complications were found in 46.8% and 40.8% of cases, respectively. The primary outcome was encountered in 29.0% (95% CI 26.6, 31.5) of participants, while 10.6% (9.0, 12.4) died and 18.0% (16.0, 20.2) were discharged on day 7. In univariate analysis, characteristics prior to admission significantly associated with the primary outcome were sex, BMI and previous treatment with renin-angiotensin-aldosterone system (RAAS) blockers, but not age, type of diabetes, HbA1c, diabetic complications or glucose-lowering therapies. In multivariable analyses with covariates prior to admission, only BMI remained positively associated with the primary outcome (OR 1.28 [1.10, 1.47]). On admission, dyspnoea (OR 2.10 [1.31, 3.35]), as well as lymphocyte count (OR 0.67 [0.50, 0.88]), C-reactive protein (OR 1.93 [1.43, 2.59]) and AST (OR 2.23 [1.70, 2.93]) levels were independent predictors of the primary outcome. Finally, age (OR 2.48 [1.74, 3.53]), treated obstructive sleep apnoea (OR 2.80 [1.46, 5.38]), and microvascular (OR 2.14 [1.16, 3.94]) and macrovascular complications (OR 2.54 [1.44, 4.50]) were independently associated with the risk of death on day 7. CONCLUSIONS/INTERPRETATIONS: In people with diabetes hospitalised for COVID-19, BMI, but not long-term glucose control, was positively and independently associated with tracheal intubation and/or death within 7 days. TRIAL REGISTRATION: clinicaltrials.gov NCT04324736.

Non-functioning pituitary adenomas (NFPA) are benign neoplasms that are first treated by surgery and secondary radiation therapy in case of residual tumor or regrowth. The consequences of surgery and radiotherapy are still debated. The objective of the work was to assess the impact of surgery, radiotherapy (RT) and pituitary deficiencies on long term health-related quality of life (QoL) and cognitive function among NFPA patients. Forty-six NFPA patients were studied after 9.6±7.5 years follow-up using: i) the MoCA questionnaire to detect mild cognitive disabilities, ii) the McNair and Kahn scale to assess perceived cognitive impairment, iii) the HADS questionnaire to score anxiety and depression, and iv) the SF-36 and QLS-H questionnaires to assess QoL. All NFPA patients had surgery and 54% patients had radiation therapy (RT+). The MoCA score was abnormal in 41% NFPA patients. Neither the type of surgery nor radiotherapy influenced the prevalence of cognitive disabilities. The depression score was higher in RT+than RT- patients. Overall, no alteration in SF-36 and QLS-H QoL scales were observed in NFPA patients when compared with the French reference population. Among NFPA patients, mental composite score, general health and vitality scores were altered in RT+compared to RT- patients. The presence of multiple pituitary axis deficiencies worsened general health and vitality scale scoring. Consistent follow-up had a beneficial impact on psycho-emotional dimensions of health. Surgery and radiotherapy had no adverse effects on cognitive functions, however, QoL was altered in RT+patients. These latter alterations may be partly related to pituitary hormone deficiencies.

TeleDiab-2 was a 13-month randomized controlled trial evaluating the efficacy and safety of two telemonitoring systems to optimize basal insulin (BI) initiation in subjects with inadequately controlled type 2 diabetes (HbA1c, 7.5%-10%). A total of 191 participants (mean age 58.7 years, mean HbA1c 8.9%) were randomized into three groups: group 1(G1, standard care, n = 63), group 2 (G2, interactive voice response system, n = 64) and group 3 (G3, Diabeo-BI app software, n = 64). The two telemonitoring systems proposed daily adjustments of BI doses, in order to facilitate the achievement of fasting blood glucose (FBG) values targeted at ~100 mg/dL. At 4 months follow-up, HbA1c reduction was significantly higher in the telemonitoring groups (G2: -1.44% and G3: -1.48% vs. G1: -0.92%; P < 0.002). Moreover, target FBG was reached by twice as many patients in the telemonitoring groups as in the control group, and insulin doses were also titrated to higher levels. No severe hypoglycaemia was observed in the telemonitoring groups and mild hypoglycaemia frequency was similar in all groups. In conclusion, both telemonitoring systems improved glycaemic control to a similar extent, without increasing hypoglycaemic episodes.

AIMS: The relative contribution of basal hyperglycaemia (BHG) and postprandial hyperglycaemia (PPHG) in type 2 diabetes patients treated with multiple daily injections (MDI) of insulin is poorly documented. In this study, the BHG and PPHG of patients from the OPT2mise study who were initially treated with MDI were assessed before randomization and again after 6 months of continuous subcutaneous insulin infusion (CSII). MATERIALS AND METHODS: Blinded continuous glucose monitoring (CGM) data were collected in 259 MDI patients after completion of an 8-week run-in period. The hyperglycaemic area under the curve (AUC) during the 24-hour basal period (AUC-B) and the postprandial period (AUC-P) were compared with analysis of variance based on contribution to total hyperglycaemia in HbA1c groups (Group 1, <8%; Group 2, 8%-8.4%; Group 3, 8.5%-8.9%; Group 4, 9%-9.4%; Group 5, ≥9.5%). Changes in AUC-B and AUC-P were assessed after 6 months of pump therapy in 131 randomized participants with available CGM recordings. RESULTS: In patients undergoing MDI therapy, AUC-B was 21.6% to 54.8% lower in Group 4 to 1 (P = .0138 and P = .0002, respectively) in comparison to Group 5. In contrast, AUC-P did not differ among HbA1c groups (P = .1009). HbA1c correlated with AUC-B, but not with AUC-P. After switching to CSII, AUC-B and AUC-P decreased by 21% and 17%, respectively. When comparing responders with non-responders to CSII therapy, no between-group differences were observed in AUC-B and AUC-P. CONCLUSIONS: Basal hyperglycaemia is the major determinant of overall exposure to hyperglycaemia in type 2 diabetes with MDI failure.

PURPOSE: Myocardial blood flow (MBF) measurement using positron emission tomography (PET) from the washout rate of (15)O-water is theoretically independent of tissue attenuation. The aim of this study was to evaluate the impact of not using attenuation correction in the assessment of coronary endothelial function and myocardial flow reserve (MFR) using (15)O-water PET. METHODS: We retrospectively processed 70 consecutive (15)O-water PET examinations obtained at rest and during cold pressor testing (CPT) in patients with dilated cardiomyopathy (n = 58), or at rest and during adenosine infusion in heart transplant recipients (n = 12). Data were reconstructed with attenuation correction (AC) and without attenuation correction (NAC) using filtered backprojection, and MBF was quantified using a single compartmental model. The agreement between AC and NAC data was assessed using Lin's concordance correlation coefficient followed by Bland-Altman plot analysis. RESULTS: Regarding endothelial function, NAC PET showed poor reproducibility and poor agreement with AC PET data. Conversely, NAC PET demonstrated high reproducibility and a strong agreement with AC PET for the assessment of MFR. CONCLUSION: Non-attenuation-corrected (15)O-water PET provided an accurate measurement of MFR compared to attenuation-corrected PET. However, non-attenuation-corrected PET data were less effective for the assessment of endothelial function using CPT in this population.

TOMORROW, WHAT EVOLUTIONS IN DIABETES ? Diabetes care has undergone a major digital nutation over the past decade. The devices used to treat and monitor patients with diabetes are increasingly "connected", generating large amounts of data. These data, hosted in clouds, facilitate the development of remote monitoring and teleconsultations in diabetology. The advent of continuous glucose monitoring (CGM) and insulin pumps has also enabled the development of control algorithms (known as "hybrid closed loops" (HCL) thhat automatically modulate insulin pump delivery rate according to real-time CGM data, in order to maintain glucose level in the normal range. HCL have proved high efficacy for patients with type 1 diabetes and are currently being assessed for other insulin-requiring diabetes type. Artificial intelligence (AI), which is currently being developed for all human actiiviities, also concerns diabetology, with a wide range of future applications in screening, diagnosis, therapy, support and research.
DEMAIN, QUELLES ÉVOLUTIONS EN DIATÉTOLOGIE? La diabétologie connaît une importante mutation mumériique depuis une décennie. Les dispositifs utilisés pour le traitement et la surveillance des patients atteints de diabète sont de plus en plus "connetés", générant de grandes quantités de données. Ces données sont hébergées sur des portails de surveillance qui facilitent le développement de la télésuurveillance et des téléconsultations en diabétologie. L'avènement des capteurs de glucose interstitiel et des pompes à insuline a également permis le développement d'algorithmes de contrôle (dits" boucles fermées"[BF]) qui modulent de façon automatisée le débit de la pompe à insuline en fonction des données du capteur en temps réel, afin de maintenir le glucose le plus proche possible de la zone normale. Ces systèmes de BF ont démontré leur grande efficacité pour les patients atteints de diabète de type 1 et sont en cours d'évaluation dans d'autres situations de diabète insulinorequérant. L'intelligence artificielle (IA), en cours de développement dans toutes les activités humaines, concerne également la diabétologie, avec des applications très diverses qui concerneront demain le dépistage, le diagnstic, la thérapeutique, l'accompagnement ou encore la recherche.

CONTEXT: The amount of consumed carbohydrates is the strongest factor influencing glucose levels during the four hours following a meal. Our aim was to evaluate the association between carbohydrate counting knowledge and continuous glucose monitoring (CGM) parameters in patients with type 1 diabetes (T1D) using different insulin regimens. METHOD: In this multicenter prospective study, the GluciQuizz questionnaire was used to evaluate carbohydrate knowledge. CGM data for the 14 days preceding completion of the questionnaire were analyzed. The primary endpoint was evaluation of the correlation between the GluciQuizz total score and time in range (TIR) in the study population. RESULTS: The mean age of the 170 participants was 40.7 ± 14.8 years and duration of T1D 18.8 ± 12.1 years. The mean GluciQuizz total score for all participants was 66 ± 13 %. Mean TIR was 58.6 ± 18.7 %. GluciQuizz total score positively correlated with TIR (r = 0.3001; p < 0.0001). This correlation was observed in CSII users (r = 0.2526; p < 0.05) but not in MDI (r = 0.2510; p = 0.1134) and HCL users (r = -0.1065; p = 0.4914). TIR was also negatively correlated with the mean carb count error in all study participants (r = -0.2317; p < 0.01). CONCLUSION: In conclusion, as the Gluciquizz score was associated with metabolic control, this easy-to-use self-administered questionnaire could be used widely on a routine basis to assess the carbohydrate knowledge of T1D patients and to offer them targeted education tailored to their needs.

Aim: Clinical trials and real-world data for Type II diabetes both show that glycated hemoglobin (HbA1c) levels and hypoglycemia occurrence can be reduced by real-time continuous glucose monitoring (rt-CGM) versus self-monitoring of blood glucose (SMBG). The present cost-utility study investigated the long-term health economic outcomes associated with using rt-CGM versus SMBG in people with insulin-treated Type II diabetes in France. Materials & methods: Effectiveness data were obtained from a real-world study, which showed rt-CGM reduced HbA1c by 0.56% (6.1 mmol/mol) versus sustained SMBG. Analyses were conducted using the IQVIA Core Diabetes Model. A French payer perspective was adopted over a lifetime horizon for a cohort aged 64.5 years with baseline HbA1c of 8.3% (67 mmol/mol). A willingness-to-pay threshold of 147,093 was used, and future costs and outcomes were discounted at 4% annually. Results: The analysis projected quality-adjusted life expectancy was 8.50 quality-adjusted life years (QALYs) for rt-CGM versus 8.03 QALYs for SMBG (difference: 0.47 QALYs), while total mean lifetime costs were 93,978 for rt-CGM versus 82,834 for SMBG (difference: 11,144). This yielded an incremental cost-utility ratio (ICUR) of 23,772 per QALY gained for rt-CGM versus SMBG. Results were particularly sensitive to changes in the treatment effect (i.e., change in HbA1c), annual price and quality of life benefit associated with rt-CGM, SMBG frequency, baseline patient age and complication costs. Conclusion: The use of rt-CGM is likely to be cost-effective versus SMBG for people with insulin-treated Type II diabetes in France.

OBJECTIVE: To evaluate the association of insulin injection adherence, smart insulin pen engagement, and glycemic control using real-world data from 16 countries from adults self-administering basal insulin degludec and bolus insulin with a smart insulin pen (NovoPen 6 or NovoPen Echo Plus) alongside continuous glucose monitoring (CGM). RESEARCH DESIGN AND METHODS: Data were aggregated over 14-day periods. Treatment adherence was defined according to the number of missed basal and missed bolus insulin doses and smart pen engagement according to the number of days with data uploads. RESULTS: Data from 3,945 adults, including 25,157 14-day periods with ≥70% CGM coverage, were analyzed. On average, 0.2 basal and 6.0 bolus insulin doses were missed over 14 days. The estimated probability of missing at least one basal insulin dose over a 14-day period was 17.6% (95% CI 16.5, 18.7). Missing one basal or bolus insulin dose per 14 days was associated with a significant decrease in percentage of time with glucose levels in range (TIR) (3.9-10.0 mmol/L), of -2.8% (95% CI -3.7, -1.8) and -1.7% (-1.8, -1.6), respectively; therefore, missing two basal or four bolus doses would decrease TIR by >5%. Smart pen engagement was associated positively with glycemic outcomes. CONCLUSIONS: This combined analysis of real-world smart pen and CGM data showed that missing two basal or four bolus insulin doses over a 14-day period would be associated with a clinically relevant decrease in TIR. Smart insulin pens provide valuable insights into treatment injection behaviors.

CONTEXT: Pheochromocytoma and paraganglioma (PPGL) are rare neuroendocrine tumors with high heritability, justifying systematic genetic screening for a germline variant in one of the twenty predisposing genes described to date. PURPOSE: To describe the experience of one endocrine oncogenetic laboratory over a period of 21 years (2001-2022), from the beginning of PPGL genotyping with Sanger sequencing in 2001 to the implementation of next-generation sequencing (NGS). METHOD: The activity database of an academic oncogenetic laboratory was searched to extract patients/relatives identified with a pathogenic variant/likely pathogenic variant (PV/LPV) over a period of 21 years. Clinical and genetic data were compared. RESULTS: In total, 606 index cases with PPGL and 444 relatives were genotyped. Genotyping of index cases was performed by Sanger sequencing and gene deletion analysis in 327 cases and by NGS in 279. Germline PV/LPV spanning 10 genes was identified in 165 index cases (27.2%). Several recurrent PV/LPVs in SDHx were observed in non-related index cases, the most frequent being SDHD, c.170-1G>T (n=28). This subgroup showed great phenotypic variability both between and within families in terms of both tumor location and number. Four patients (1.1%) with PV/LPV in SDHx had 3PA (Pituitary Adenoma and pheochromocytoma/paraganglioma) syndrome. 258 relatives (58.1%) had inherited a PV/LPV in one driver gene. The rate of PV/LPV carriers who were symptomatic at first imaging evaluation was 32%, but varied between<20% in SDHB and SDHC and >50% in SDHD, VHL and MAX. CONCLUSION: Our experience confirmed previously established genotype-phenotype correlations, but also highlights atypical clinical presentations, even for the same genetic variant. These data must be taken into account for optimal patient follow-up and management.

Aim: To evaluate the evolution of glycemic outcomes in patients living with type 1 diabetes (T1D) after 1 year of use of the MiniMed 780G advanced hybrid closed-loop (AHCL) system. Methods: We conducted an observational, retrospective, multicentric study in 20 centers in France. The primary objective was to evaluate the improvement in glycemic control after 1-year use of AHCL. The primary endpoint was the variation of time in range (TIR) between pre-AHCL and after 1-year use of AHCL. Secondary objectives were to analyze the glycemic outcomes after 3, 6, and 12 months of AHCL use, the safety, and the long-term observance of AHCL. Results: Two hundred twenty patients were included, and 200 were analyzed for the primary endpoint. 92.7% of patients continued to use AHCL. After 1 year of use of AHCL, TIR was 72.5% ± 10.6% (+9.1%; 95% confidence interval [CI] [7.6-10.5] compared to pre-AHCL initiation, P < 0.001), HbA1c 7.1% ± 0.7% (-0.5%; 95% CI [-0.6 to -0.4]; P < 0.001), time below range 2.0% [1.0; 3.0] (0.0% [-2.0; 0.0], P < 0.001), and time above range 24.8% ± 10.9% (-7.3%; 95% CI [-8.8 to -5.7]; P < 0.001). More patients achieved the glycemic treatment goals of HbA1c <7.0% (45.1% vs. 18.1%, P < 0.001) and TIR >70% (59.0% vs. 29.5% P < 0.001) when compared with pre-AHCL. Five patients experienced severe hypoglycemia events and two patients experienced ketoacidosis. Conclusion: After 1 year of use of AHCL, people living with T1D safely improved their glucose control and a higher proportion of them achieved optimal glycemic control.

The morbidity and mortality of pancreatic cancer surgery has seen substantial improvement due to the standardization of surgical techniques, the optimization of perioperative multidisciplinary management and the organization of specialized care systems. The identification and treatment of postoperative functional and nutritional sequelae have thereby become major issues in patients who undergo pancreatic surgery. This review addresses the functional sequelae of pancreatic resection for cancerous and pre-cancerous lesions (excluding chronic pancreatitis). Its aim is to specify the prevalence and severity of sequelae according to the type of pancreatic resection and to document, where appropriate, the therapeutic management. Exocrine pancreatic insufficiency (ExPI) is observed in nearly one out of three patients at one year after surgery, and endocrine pancreatic insufficiency (EnPI) is present in one out of five patients after pancreatoduodenectomy (PD) and one out of three patients after distal pancreatectomy (DP). In addition, digestive functional disorders may appear, such as delayed gastric emptying (DGE), which affects 10 to 45% of patients after PD and nearly 8% after DP. Beyond these functional sequelae, pancreatic surgery can also induce nutritional and vitamin deficiencies secondary to a lack of uptake for certain vitamins or to the loss of absorption site in the duodenum. In addition to the treatment of ExPI with oral pancreatic enzymes, nutritional management is based on a high-calorie, high-protein diet with normal lipid intake in frequent small feedings, combined with vitamin supplementation adapted to monitored deficiencies. Better knowledge of the functional consequences of pancreatic cancer surgery can improve the overall management of patients.

AIMS: Glycemic variability has been suggested as a risk factor for diabetes complications but the precise deleterious mechanisms remain poorly understood. Since mitochondria are the main source of energy in heart and cardiovascular diseases remain the first cause of death in patients with diabetes, the aim of the study was to evaluate the impact of glucose swings on mitochondrial functions in the cardiomyocyte cell line HL-1. METHODS: HL-1 cells were exposed to low (LG, 2.8 mmol/l), normal (NG, 5.5 mmol/l), high (HG, 25 mmol/l) or intermittent high glucose (IHG, swing between low and high) every 2h during 12h (short-time treatment) or every 12h during 72h (long-time treatment). Anaerobic catabolism of glucose was evaluated by measuring glucose consumption and lactate production, oxidative phosphorylation was evaluated by polarography and ATP measurement, mitochondrial superoxide anions and the mitochondrial membrane potential (MMP) were analysed using fluorescent probes, and the protein oxidation was measured by oxyblot. RESULTS: IHG and HG increased glucose consumption and lactate production compared to LG and NG but without any difference between short- and long-time treatments. After 72h and unlike to LG, NG and HG, we didn't observe any increase of the mitochondrial respiration in the presence of succinate upon IHG treatment. IHG, and to a lesser extent HG, promoted a time-dependent decrease of the mitochondrial membrane potential compared to LG and NG treatments. HG and IHG also increased superoxide anion production compared to LG and NG both at 12 and 72h but with a higher increase for IHG at 72h. At last, both HG and IHG stimulated protein oxidation at 72h compared to LG and NG treatments. CONCLUSIONS: Our results demonstrated that exposure of HL-1 cells to glucose swings promoted time-dependent mitochondrial dysfunctions suggesting a deleterious effect of such condition in patients with diabetes that could contribute to diabetic cardiomyopathy.
