BACKGROUND: Advances in paediatric type 1 diabetes management and increased use of diabetes technology have led to improvements in glycaemia, reduced risk of severe hypoglycaemia, and improved quality of life. Since 1993, progressively lower HbA1c targets have been set. The aim of this study was to perform a longitudinal analysis of HbA1c, treatment regimens, and acute complications between 2013 and 2022 using data from eight national and one international paediatric diabetes registries. METHODS: In this longitudinal analysis, we obtained data from the Australasian Diabetes Data Network, Czech National Childhood Diabetes Register, Danish Registry of Childhood and Adolescent Diabetes, Diabetes Prospective Follow-up Registry, Norwegian Childhood Diabetes Registry, England and Wales' National Paediatric Diabetes Audit, Swedish Childhood Diabetes Registry, T1D Exchange Quality Improvement Collaborative, and the SWEET initiative. All children (aged ≤18 years) with type 1 diabetes with a duration of longer than 3 months were included. Investigators compared data from 2013 to 2022; analyses performed on data were pre-defined and conducted separately by each respective registry. Data on demographics, HbA1c, treatment regimen, and event rates of diabetic ketoacidosis and severe hypoglycaemia were collected. ANOVA was performed to compare means between registries and years. Joinpoint regression analysis was used to study significant breakpoints in temporal trends. FINDINGS: In 2022, data were available for 109 494 children from the national registries and 35 590 from SWEET. Between 2013 and 2022, the aggregated mean HbA1c decreased from 8·2% (95% CI 8·1-8·3%; 66·5 mmol/mol [65·2-67·7]) to 7·6% (7·5-7·7; 59·4mmol/mol [58·2-60·5]), and the proportion of participants who had achieved HbA1c targets of less than 7% (<53 mmol/mol) increased from 19·0% to 38·8% (p<0·0001). In 2013, the aggregate event rate of severe hypoglycaemia rate was 3·0 events per 100 person-years (95% CI 2·0-4·9) compared with 1·7 events per 100 person-years (1·0-2·7) in 2022. In 2013, the aggregate event rate of diabetic ketoacidosis was 3·1 events per 100 person-years (95% CI 2·0-4·8) compared with 2·2 events per 100 person-years (1·4-3·4) in 2022. The proportion of participants with insulin pump use increased from 42·9% (95% CI 40·4-45·5) in 2013 to 60·2% (95% CI 57·9-62·6) in 2022 (mean difference 17·3% [13·8-20·7]; p<0·0001), and the proportion of participants using continuous glucose monitoring (CGM) increased from 18·7% (95% CI 9·5-28·0) in 2016 to 81·7% (73·0-90·4) in 2022 (mean difference 63·0% [50·3-75·7]; p<0·0001). INTERPRETATION: Between 2013 and 2022, glycaemic outcomes have improved, parallel to increased use of diabetes technology. Many children had HbA1c higher than the International Society for Pediatric and Adolescent Diabetes (ISPAD) 2022 target. Reassuringly, despite targeting lower HbA1c, severe hypoglycaemia event rates are decreasing. Even for children with type 1 diabetes who have access to specialised diabetes care and diabetes technology, further advances in diabetes management are required to assist with achieving ISPAD glycaemic targets.

AIM: A diabetes-related foot ulcer (DFU) is a major risk factor for lower-extremity amputation (LEA). To help clinicians predict the risk of LEA in people with DFU, the Diabetic Foot Risk Assessment (DIAFORA) system was developed but has never been externally validated. METHODS: In this study, 317 people presenting with a new DFU were included. At baseline, participants were grouped into three groups based on their DIAFORA score: low-risk (<15), medium-risk (15-25), and high-risk (>25). Participants were followed until healing, LEA, death, or at least 3 months. Discriminative accuracy was evaluated using sensitivity, specificity, likelihood ratios (LRs) and the area under the curve (AUC). RESULTS: All 317 participants completed at least 3 months of follow-up for a median duration of 146 days, during which 12.6% underwent minor amputation and 2.5% major amputation. People in the low- and medium-risk categories had major amputation rates of 0.9% and 2.1%, respectively, and negative LR of major LEA of 0.10 and 0.38, respectively, while the people in the high-risk category had an amputation rate of 25.0% and a positive LR of 12.9. The DIAFORA risk groups had a sensitivity of 75.0% and a specificity of 65.7%, with a corresponding AUC of 0.78 (95% CI 0.68-0.87) for the prediction of major LEA. CONCLUSION: The DIAFORA score is a useful tool for risk stratification of people presenting with a newly occurred DFU, with the external validation presenting results similar to those presented in the original study. The DIAFORA score may guide clinicians towards more individualized DFU treatment regimens.

PURPOSE: Obesity and its related severe comorbidities are increasing rapidly. The duodenal-jejunal bypass is an endoscopically implanted device (mimicking the Roux-en-Y gastric bypass) developed to support weight reduction and improve type 2 diabetes control. MATERIALS AND METHODS: Retrospective data analysis of consecutive patients undergoing duodenal-jejunal bypass (EndoBarrier®, DJB) implantation between 2013 and 2017 was performed to evaluate safety as well as short- and long-term efficacy. RESULTS: One hundred and twenty-one patients (mean BMI of 43.1 ± 7.2 kg/m2 and weight of 138.2 ± 28.6 kg) underwent DJB implantation. The mean dwelling time was 15.5 months, the mean total body weight loss (%TBWL) after explantation was 10.3% ± 7.9% (14.2 kg, p < 0.0001), and the mean BMI was 39.5 ± 7.3 kg/m2 (p < 0.0001). There was no significant weight gain 24 months after the explantation. Seventy-seven patients had type 2 diabetes mellitus (T2DM) with a mean HbA1c before implantation of 5.6% (n = 52). The mean HbA1c after explantation was 5.1% (p = 0.0001). Significant reductions in transaminase and lipid levels before and after explantation were observed. One complication occurred during implantation and another during explantation. In 16 patients, the device had to be extracted earlier than expected (7 for severe adverse events and 9 for adverse events; 13.2%). CONCLUSION: Despite an evident rate of adverse events, the DJB shows promise as a weight-loss procedure. Our results show that some patients implanted with the device maintained reduced weight even 24 months after explantation, while many improved T2DM control.

Diabetes mellitus is a chronic disease affecting glucose metabolism. The pathophysiological reactions underpinning the disease can lead to the development of late diabetes complications. The gut microbiota plays important roles in weight regulation and the maintenance of a healthy digestive system. Obesity, diabetes mellitus, diabetic retinopathy, diabetic nephropathy and diabetic neuropathy are all associated with a microbial imbalance in the gut. Modern technical equipment and advanced diagnostic procedures, including xmolecular methods, are commonly used to detect both quantitative and qualitative changes in the gut microbiota. This review summarises collective knowledge on the role of the gut microbiota in both types of diabetes mellitus and their late complications, with a particular focus on diabetic foot syndrome.

OBJECTIVE: By exposing mice carrying a deletion of NADPH oxidase isoform 4, NOX4, specifically in pancreatic β cells (βNOX4-/-) to nutrient excess stimulated by a high-fat diet (HFD), this study aimed to elucidate the role of β-cell redox status in the development of meta-inflammation within the diabetic phenotype. METHODS: The authors performed basic phenotyping of βNOX4-/- mice on HFD involving insulin and glycemic analyses, histochemistry of adipocytes, indirect calorimetry, and cytokine analyses. To characterize local inflammation, the study used caspase-1 activity assay, interleukin-1β immunochemistry, and real-time polymerase chain reaction during coculturing of β cells with macrophages. RESULTS: The phenotype of βNOX4-/- mice on HFD was not associated with hyperinsulinemia and hyperglycemia but showed accumulation of excessive lipids in epididymal fat and β cells. Surprisingly, mice showed significantly reduced systemic inflammation. Decreased interleukin-1β protein levels and downregulated NLRP3-inflammasome activity were observed on chronic glucose overload in βNOX4-/- isolated islets and NOX4-silenced INS1-E cells resulting in attenuated proinflammatory polarization of macrophages/monocytes in vitro and in situ and reduced local islet inflammation. CONCLUSIONS: Experimental evidence suggests that NOX4 pro-oxidant activity in β cells is involved in NLRP3-inflammasome activation during chronic nutrient overload and participates in local inflammatory signaling and perhaps toward peripheral tissues, contributing to a diabetic inflammatory phenotype.
Klinický problém hypoglykémie je prítomný v diabetológii už od objavu inzulínu pred viac ako 100 rokmi. Nové technológie v manažmente diabetu, akými sú kontinuálne monitorovanie glukózy (Continuous Glucose Monitoring – CGM) alebo inzulínové pumpy integrované s CGM technológiou do hybridných uzavretých systémov na podávanie inzulínu (Advanced Hybrid Closed Loop Systems – AHCL) majú jednoznačné dôkazy pre signifikantnú a klinicky relevantnú redukciu výskytu hypoglykémie. CGM technológia, okrem samotného efektu na redukciu výskytu hypoglykémie, pomohla v prvom rade odhaliť jej skutočnú a predtým nepoznanú mieru výskytu. Autor v prehľadovom článku diskutuje relevantné klinické štúdie a dáta z reálnej praxe (Real World Evidence – RWE) a ich význam pre klinickú prax.
The clinical problem of hypoglycaemia has been with us since the discovery of insulin more than 100 years ago. Modern diabetes technologies, such as continuous glucose monitoring (CGM) or advanced hybrid closed loop systems (AHCL), have unequivocal evidence for significant and clinically meaningful reduction of hypoglycaemia. On top of that, CGM technology has helped us to discover the real extent of the hypoglycaemia ‘problem’ in the lives of our patients. This article reviews the relevant clinical studies and real world evidence data and their impact on clinical practice.
Chronická obličková choroba sa u pacientov s alebo bez diabetes mellitus spája so zvýšeným rizikom hypoglykémie, hlavne dôsledkom poruchy glukoneogenézy a redukcie degradácie inzulínu v obličkách. Hypoglykémia sa často vyskytuje u hemodialyzovaných pacientov. Riziko hypoglykémie u týchto pacientov sa zvyšuje pri tesnej glykemickej kontrole pri liečbe inzulínom alebo perorálnymi antidiabetikami, použití dialyzačných roztokov bez glukózy a malnutrícii. V prevencii hypoglykémie u hemodialyzovaných pacientov s diabetes mellitus sa odporúča podávanie dialyzačných roztokov s koncentráciou glukózy v rozmedzí 5,5–11,1 mmol/l, individuálna titrácia dávky inzulínu a menej prísne cieľové hodnoty glykovaného hemoglobínu 7–8 % podľa DCCT v prípade opakovaných hypoglykémií.
Chronic kidney disease in patients with or without diabetes mellitus is associated with higher risk of hypoglycemia, mainly due to defect of kidney gluconeogenesis and reduction of renal insulin clearance. Hypoglycemia often occurs in patients on hemodialysis. Risk of hypoglycemia in these patients is increased in the case of strict glycemic control during treatment by insulin or oral antidiabetics, using of dialysate solutions without glucose and malnutrition. In prevention of hypoglycemia in hemodialyzed diabetic patients there is recommended using of dialysate solutions with glucose concentration 5.5–11.1 mM/L, individual titration of insulin dose and less strict goals of glycosylated hemoglobin values 7–8 % according to DCCT in the case of repeated hypoglycemias.
Hypoglykémia v starobe je spojená s významnými chorobnosťami vedúcimi k fyzickej aj kognitívnej dysfunkcii. Opakované hospitalizácie v dôsledku častých hypoglykémií sú tiež spojené s ďalším zhoršovaním celkového zdravotného stavu pacientov. Tento negatívny vplyv hypoglykémie pravdepodobne nakoniec povedie ku krehkosti, invalidite. Zdá sa, že vzťah medzi hypoglykémiou a krehkosťou je obojsmerný a je sprostredkovaný radom vplyvov vrátane podvýživy. Preto je potrebné venovať pozornosť manažmentu podvýživy u geriatrických pacientov zlepšením energetického príjmu a udržaním svalovej hmoty. Dôležité je zamerať sa na zvýšenie fyzickej aktivity a konzervatívnejší prístup ku glykemickým cieľom u krehkých starších diabetikov.
Hypoglycemia in elderly is associated with significant morbidities leading to both physical and cognitive dysfunction. Repeated hospital admissions due to frequent hypoglycemia are also associated with further deterioration in patients’ general health. This negative impact of hypoglycemia is likely to eventually lead to frailty and disability. It appears that the relationship between hypoglycemia and frailty is bidirectional and mediated through a series of influences including under nutrition. Therefore, attention should be paid to the management of under nutrition in the general elderly population by improving energy intake and maintaining muscle mass. Increasing physical activity and having a more conservative approach to glycemic targets in frail geriatric patients with diabetes may be worthwhile.
Pankreatoprivní diabetes je sekundární forma se stejnou prevalencí v evropské populaci jako diabetes mellitus 1. typu. Nejčastější příčinou je chronická pankreatitida, se kterou úzce souvisí i resekční výkony. Extrémně labilní formou je diabetes po totální pankreatektomii. Tento typ diabetu je charakterizován častým výskytem hypoglykemií, a to i těžkých epizod. Účinnou prevenci vzniku diabetu je autotransplantace ostrůvků, která se provádí od roku 1980. Tato léčba efektivně brání vzniku diabetu u třetiny pacientů a u ostatních nemocných významně snižuje výskyt hypoglykemií. Pokud tento výkon nelze provést, je vhodné pacienty monitorovat pomocí senzorů a pokusit se je léčit hybridními smyčkami. V budoucnu přicházejí do úvahy také bihormonální pumpy.
Pancreaticobiliary diabetes is a secondary form with the same prevalence in the European population as type 1 diabetes mellitus. The most common cause is chronic pancreatitis, with which resection procedures are closely related. An extremely labile form is diabetes after total pancreatectomy. This type of diabetes is characterized by frequent occurrence of hypoglycemia and even severe episodes. An effective prevention of diabetes is islet autotransplantation, which has been performed since 1980. This treatment effectively prevents diabetes in one third of patients and significantly reduces the incidence of hypoglycemia in the remaining patients. If this procedure cannot be performed, it is advisable to monitor patients with sensors and try to treat them with hybrid loops.
