Background and Aim: Type 2 diabetes (T2D) continues to pose a significant public health challenge worldwide. Among therapeutic options, glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have proven effective in optimizing glycemic control and improving cardiometabolic profiles. Semaglutide, now available in an oral formulation, represents a modern strategy to improve patient adherence while supporting glucose and weight regulation. This study primarily investigated the effects of oral semaglutide on key metabolic indicators and secondary endpoints included cardiovascular risk markers (blood pressure and lipid profile) and patient-reported quality of life (QoL). Study Design and Methods: A longitudinal, prospective observational study was conducted involving patients with T2D across two Italian healthcare facilities. Participants were assessed at baseline (T0) and at three subsequent intervals—6 months (T1), 12 months (T2), and 18 months (T3)—following the initiation of oral semaglutide use. Key Findings: Out of 116 participants enrolled, 97 had complete and analyzable data. Across the 18-month follow-up, significant improvements were observed in glycemic parameters, with a notable reduction in HbA1c levels (T0 vs. T3, p = 0.0028; p ≤ 0.05, statistically significant). Self-reported outcomes showed enhanced quality of life, especially in treatment satisfaction and perceived flexibility (T0 vs. T3, p < 0.001). Conclusions: Daily administration of 14 mg oral semaglutide in individuals with T2D resulted in substantial benefits in glycemic regulation, weight reduction, cardiovascular risk management, and overall patient satisfaction. These findings reinforce its potential role as a sustainable and effective option in long-term diabetes care from both a clinical and public health perspective. Full article

Background/Objectives: Primary liver cancer (PLC), encompassing hepatocellular carcinoma (HCC) and cholangiocarcinoma (CCA), constitutes a growing global health concern. Metabolic dysfunction-associated Steatotic Liver Disease (MASLD) and Type 2 diabetes mellitus (T2DM) represent a recurrent epidemiological overlap. Individuals with MASLD and T2DM (MASLD-T2DM) are at a higher risk of PLC. This scoping review highlights the epidemiological burden, the classic and novel pathogenetic frontiers, and the potential strategies optimizing the management of PLC in MASLD-T2DM. Methods: A systematic search of the PubMed, Medline, and SCOPUS electronic databases was conducted to identify evidence investigating the pathogenetic mechanisms linking MASLD and T2DM to hepatic carcinogenesis, highlighting the most relevant targets and the relatively emerging therapeutic strategies. The search algorithm included in sequence the filter words: “MASLD”, “liver steatosis”, “obesity”, “metabolic syndrome”, “body composition”, “insulin resistance”, “inflammation”, “oxidative stress”, “metabolic dysfunction”, “microbiota”, “glucose”, “immunometabolism”, “trained immunity”. Results: In the MASD-T2DM setting, insulin resistance (IR) and IR-induced mechanisms (including chronic inflammation, insulin/IGF-1 axis dysregulation, and autophagy), simultaneously with the alterations of gut microbiota composition and functioning, represent crucial pathogenetic factors in hepatocarcinogenesis. Besides, the glucose-related metabolic reprogramming emerged as a crucial pathogenetic moment contributing to cancer progression and immune evasion. In this scenario, lifestyle changes, simultaneously with antidiabetic drugs targeting IR-related effects and gut-liver axis, in parallel with novel approaches modulating immunometabolic pathways, represent promising strategies. Conclusions: Metabolic dysfunction, classically featuring MASLD-T2DM, constitutes a continuously expanding global issue, as well as a critical driver in PLC progression, demanding integrated and personalized interventions to reduce the future burden of disease.

Background: Diabetes mellitus is associated with worse outcomes after cardiac arrest. Hyperglycemia, diabetes treatments and other long-term sequalae may contribute to this association. We sought to determine the acute effect of diabetes on the return of spontaneous circulation (ROSC) and post-arrest cardiac function in a rat cardiac arrest model. Methods: Eighteen male Wistar rats were utilized, and 12 underwent the induction of type II diabetes for 10 weeks through a high-fat diet and the injection of streptozotocin. The carotid artery flow and femoral arterial pressure were measured. Seven minutes of asphyxial cardiac arrest was induced. An external cardiac compression was performed via an automated piston. Post-ROSC, epinephrine was titrated to a mean arterial pressure (MAP) of 70 mmHg. Data was analyzed using the Mann–Whitney test. The significance was set at p ≤ 0.05. Results: The rate of the ROSC was significantly lower in animals with diabetes, 50% compared to 100% in non-diabetics. Additionally, it took significantly longer to achieve the ROSC in diabetics, p = 0.034. In animals who survived, the cardiac function was reduced, as indicated by an increased epinephrine requirement, p = 0.041, and a decreased cardiac output at the end of the experiment, p = 0.017. The lactate, venous and arterial pressures, heart rate and carotid flow did not differ between groups at 2 h. Conclusions: Diabetes negatively affects the survival from cardiac arrest. Here, the critical difference was the rate of the conversion to a life-sustaining rhythm and the achievement of the ROSC. The post-ROSC cardiac function was depressed in diabetic animals. Interventions targeted at improving defibrillation success may be important in diabetics. Full article

Background/Objectives: Physical activity is a cornerstone of diabetes mellitus (DM) management and is strongly recommended in the American Diabetes Association (ADA)’s guidelines. This study aims to investigate the self-reported physical activity levels of individuals with DM in Germany, as well as the barriers and facilitators they encounter. Methods: Individuals with type 1 DM (T1DM) and type 2 DM (T2DM) were asked to fill out an online questionnaire that was partly based on the International Physical Activity Questionnaire (IPAQ). Results: The questionnaire was completed by 338 persons with either T1DM (57.1%) or T2DM (42.9%) (females: 56.2%, males: 42.0%, gender diverse persons: 1.8%) of all age groups (at least 18 years). In total, 80.5% of respondents were aware of the current physical activity recommendations. Among the respondents, 58% reported meeting the recommendations for endurance-type physical activity, while only 30.5% reported meeting those for strength training. The three most frequently cited barriers to physical activity were lack of time, lack of motivation and current state of health. Supporting factors included coverage of costs, availability of exercise programs in close proximity to the patient’s home and target group specific exercise programs. Conclusions: The results imply that many individuals with DM in Germany do not meet ADA’s physical activity recommendations, especially considering that self-reports often overestimate actual behavior. In particular, the actual number of individuals who regularly engage in strength training may be too low. There is a clear need to better communicate the benefits of different forms of physical training and to provide physical activity programs aligned with patients’ individual needs. Full article

Objectives: This study explored perceptions, experiences, and outcomes associated with the choice of insulin therapies among pediatric patients with type 1 diabetes mellitus (T1D). Methods: This study included 20 adolescents (8 male and 12 female) with T1D, with a mean age of 15.05 ± 0.91 years, a mean diabetes duration of 5.19 ± 1.2 years, and a mean most recent HbA1c of 7.03 ± 0.16%. Ten of the participants were using an insulin pump (n = 10) and another 10 had either refused (n = 7) or discontinued (n = 3) insulin pump therapy. A qualitative inductive method was employed, using in-depth individual interviews. The interview material was transcribed verbatim and grounded theory was used to analyze the verbal material. Results: Four main thematic categories were identified from the narrations that captured both common and divergent perceptions of insulin pump users versus non-users: (1) adjusting to the lifelong diagnosis, (2) exposing diabetes versus hiding it, (3) becoming autonomous and integrating insulin pump therapy into daily life, and (4) worrying over the pump. The third theme, capturing autonomy and integration, surfaced as the core thematic category of this study. Conclusions: This grounded theory study revealed that, by using insulin pump therapy, adolescent T1D patients can enhance their autonomy and facilitate the integration of insulin treatment into their life. This study identified processes that inform diabetes education and contribute to ameliorating gaps in the uptake and maintenance of pump therapy in pediatric care. Full article

Background/Objectives: Compared to in the general pregnant population, pregnancy in women with type 1 diabetes (T1D) is still associated with an increased number of perinatal complications affecting both the fetus and the mother. The Great Orchestra of Christmas Charity Foundation (GOCCF) program enables the use of continuous subcutaneous insulin infusion (CSII) enhanced by a hypo-stop function and real-time continuous glucose monitoring (rtCGM) during the preconception or early pregnancy period in patients with T1D. This observational study aimed to analyze the association between pregnancy planning and pregnancy outcomes in patients who qualified for the GOCCF program. Methods: Ninety-eight women with T1D, aged 21–41 years, who began using the CSII + rtCGM system at the planning/early pregnancy stage or at a later stage in the case of an unplanned pregnancy, were eligible for this study. We analyzed glucose control, the insulin requirements, the pregestational BMI, the maternal weight gain, the occurrence of preterm births, congenital malformations and the birthweight of newborns. Results: Women who planned their pregnancies had significantly better glycemic control before and throughout the entire pregnancy, and a significantly higher proportion of them achieved a TIR (time in range) > 70% (58.7% vs. 28.9%, p = 0.014) and TAR (time above range) < 25% (65.2% vs. 24.4%, p < 0.001). Their glucose variability at the end of the pregnancy was significantly lower (29.4 ± 5.5 vs. 31.9 ± 5.1, p = 0.030). They also gave birth later, at a mean of 37.8 ± 0.9 weeks compared to 36.9 ± 1.8 weeks in the non-planned group (p = 0.039). Preterm birth occurred in five women (10.4%) who planned their pregnancies and in fifteen women (30%) who did not, with p = 0.031. Conclusions: Pregnancy planning in women with type 1 diabetes (T1D) is associated with better glucose control before conception and throughout the entire pregnancy, resulting in better pregnancy outcomes.

Aim: To compare diabetic polyneuropathy (DPN) and cardiac autonomic neuropathy (CAN) between T1DM and T2DM patients. Methods: This study enrolled 66 T1DM and 79 T2DM patients. DPN was evaluated using three different methods: clinical examination, using neuropathy symptom score (NSS) and neuropathy disability score (NDS), current perception threshold (CPT) using Neurometer, and nerve conduction studies (NCSs). CAN was assessed by cardiovascular autonomic reflex tests (CARTs). Results: The prevalence of DPN did not differ between T1DM and T2DM (p > 0.05 for all), however, the proportion of DPN depended on the method used and was highest with CPT (53.0% vs. 46.8%), followed by NCSs (44.1% vs. 41.2%) and clinical examination (25.8% vs. 31.6%). T2DM vs. T1DM patients were more often diagnosed with painful DPN (51.9% vs. 27.3%, p = 0.004), reduced perception of vibration (72.2% vs. 48.5%, p = 0.006), and autonomic neuropathy (59.5% vs. 32.3%, p = 0.001), while NCSs revealed more prevalent motor nerve dysfunction in T1DM compared to T2DM (41.2% vs. 19.6%). Multivariate regression analysis showed increased DPN risk with age and CAN risk with worsening of eGFR in T1DM. No significant associations remained after multivariate adjustment for T2DM. Conclusions: The prevalence of DPN is highly varied and depends on the diagnostic method used. T2DM patients more often had symptoms and signs of diabetic neuropathy. However, stronger associations with risk factors were observed in T1DM. Full article

Objective: This study aimed to determine the possibility of creating a new animal model in which diabetic retinopathy (DR) progresses due to hypertension caused by salt loading. Methods: Male Spontaneously Diabetic Torii (SDT) fatty rats were divided into two groups: one group received 0.3% saline water starting at 8 weeks of age for a duration of 16 weeks (salt SDT fatty group), while the control group was provided with tap water (SDT fatty group). In addition, Sprague-Dawley (SD) rats receiving tap water served as normal controls. Retinal function was assessed by electroretinography (ERG) at 8 and 24 weeks of age. At 24 weeks, following perfusion with fluorescein dextran, the eyes were enucleated, and retinal flat mounts were prepared for vascular evaluation. Retinal thickness and the number of retinal folds were assessed histologically, and ultrastructural changes in the retina were examined using transmission electron microscopy. Results: Saline administration did not lead to significant changes in food consumption or body weight among the groups. In the salt SDT fatty group, blood pressure was significantly elevated, while blood glucose levels showed a slight reduction. ERG analysis showed that the amplitude of oscillatory potential (OP)1 waves was suppressed, and the latencies of OP3, OP4, and OP5 waves were prolonged. Although no significant changes were noted in retinal thickness or the number of retinal folds, thickening of the retinal capillary basement membrane was evident in the salt SDT fatty group. Conclusions: Hypertension induced by 0.3% saline promotes DR progression in SDT fatty rats. This model may help clarify the role of hypertension in DR. Full article

According to the National Institutes of Health, approximately 465 million individuals are affected by type II diabetes mellitus (T2DM) and could benefit from managing their condition with a high-quality diet based on proper, nutrient-rich food choices. A plant-based diet not only has health benefits but also helps mitigate climate change by reducing greenhouse gas emissions, but the Mediterranean diet has the most beneficial effect on overall health. In contrast, ultra-processed foods have a negative impact on T2DM outcomes. Reviewing the nutritional profile of different meals, snacks and desserts would be helpful in enhancing their quality, strengthening the role of dietitians and doctors and protecting against T2DM complications. This approach would also increase simplification and education for consumers. The PubMed-Medline, Web of Science, Scopus and Cochrane Library databases were searched for relevant articles published up to May, from 2000 (based on publication date). The results support the need to reinforce health claims and highlight public demand for food choices while also improving patient quality of life. Full article

Background/Objectives: Hypoglycemia occurs when blood glucose levels drop significantly below the normal range leading to unpleasant symptoms and a greater risk of acute complications. Fear of hypoglycemia (FH) is a conditioned psychological response to hypoglycemia frequently experienced by people with type 1 diabetes (T1D) and their loved ones. The present study aimed to examine the psychometric properties of a Portuguese translation of the Hypoglycemia Fear Survey—Parents (HFS-P) for the parents of youths with T1D. Methods: The sample consisted of 102 parents (M = 44.58 years old; SD = 5.01; mothers = 92.2%) of youths with T1D (8 to 17 years of age; M = 12.67; SD = 2.58). Confirmatory Factor Analysis (CFA) and convergent validity were performed to examine the factor structure and the construct validity of the HFS-P. Results: CFA supports a refined two-factor 18-item version of the HFS-P. The results indicate good psychometric properties (χ² [129] = 220.47.; p ≤ 0.001; χ²/DF = 1.71; RMSEA = 0.08; SRMR = 0.07; CFI = 0.93; TLI = 0.91; GFI = 0.93) along with good to excellent internal consistency coefficients (behavior subscale: α = 0.81, total: α = 0.93, and worry: α = 0.94). Conclusions: Our Portuguese version of the HFS-P appears reliable for assessing FH in parents of youths with T1D, and is ready for use in clinical research and to evaluate psychological interventions targeting parental FH in the Portuguese context.

Background/Objectives: This study aimed to evaluate adipose tissue dysfunction, assessed through adipocytokines and proinflammatory cytokines, in relation to hepatic steatosis (HS) in patients with newly diagnosed type 2 diabetes (T2D). Methods: An observational study evaluated 155 consecutive patients with new-onset T2D; 118 (76.1%) were found to have HS, while the remaining 37 served as the control group without steatosis. Anthropometric status and body mass index (BMI) were evaluated. The biochemical assessment encompassed the measurements of fasting serum lipids, fasting plasma glucose (FPG), liver function tests, adiponectin, leptin, resistin, tumor necrosis factor (TNF-α), and interleukin 6 (IL-6). Insulin resistance (IR) was determined using the homeostasis model assessment (HOMA). HS was evaluated using ultrasonographic criteria. Quantitative evaluation of HS was performed by calculating the hepatic steatosis index (HSI). Results: There were statistically significant differences between the groups for age, BMI, weight, waist circumference (WC) and hip circumference, HSI, glucose profile (fasting plasma glucose (FPG), HOMA-IR), liver function tests, adiponectin, leptin, resistin, TNF-α, and IL-6. In multivariate logistic regression analysis, age, smoking, BMI, WC, HOMA-IR, and hypoadiponectinemia were the only independent factors associated with HS. Conclusions: The adipose tissue dysfunction assessed through adipocytokines and proinflammatory cytokines is part of the associated disorders in HS and new-onset T2D. In patients with newly diagnosed T2D, age, smoking, and hypoadiponectinemia consistently emerged as independent predictors of hepatic steatosis. More prospective trials are needed to clarify the “the temporal onset” of adipose tissue dysfunction. Full article

Background: Advanced hybrid closed-loop (AHCL) systems have improved the glycemic control in type 1 diabetes (T1D). While time in range (TIR) (70–180 mg/dL) is the standard metric, time in tight range (TITR) (70–140 mg/dL) offers a stricter assessment. Real-world comparisons using the TITR are limited. This study compared the TIR and TITR metrics between the MiniMed™ 780G and Tandem Control-IQ™ in adults with T1D. Methods: This retrospective, single-center study included 42 propensity-score-matched adults with T1D (28 MM780G users and 14 Tandem Control-IQ users), each with ≥3 months of AHCL system use. Glycemic metrics from continuous glucose monitoring (CGM) were analyzed over a 14-day period. Comparisons between groups were conducted using Mann–Whitney U tests, adjusted linear regression, and linear mixed-effects models accounting for repeated measures. Results: At three months, the MM780G users achieved significantly higher TITR (60.1% ± 12 vs. 49.5% ± 9.3; p = 0.005) and TIR (83.7% ± 7.6 vs. 72.1% ± 7.5; p < 0.001) values, along with lower glucose variability, compared to these values in the Tandem Control-IQ users. The linear regression model confirmed that the MM780G was independently associated with a higher TITR (β = 14.2; p = 0.005). Mixed-effects modeling for the TIR showed a significant interaction between timepoint and device type (β = 4.81; p = 0.006), favoring the MM780G. Conclusions: In this real-world analysis, both AHCL systems improved glycemic control, but the MiniMed 780G could be associated with a superior performance in achieving tighter glucose targets without increasing hypoglycemia. TITR may serve as a valuable complementary metric alongside TIR in evaluating AHCL systems’ effectiveness. However, these findings should be interpreted cautiously due to limitations such as the retrospective design, small sample size, potential residual confounding, and lack of standardization in the device settings. Further studies are warranted to confirm these results and assess their generalizability. Full article

Background/Objectives: Type 2 diabetes mellitus (T2DM) is frequently associated with depressive disorder (DD), which negatively impacts glycemic control and overall metabolic outcomes. Recent evidence suggests that glucagon-like peptide-1 receptor agonists (GLP-1 RAs) may exert neuroprotective effects and modulate mood. Likewise, it is unknown whether the presence of a DD, due to increased brain inflammation, could lead to a poorer response to GLP-1 RAs in terms of weight loss. This study evaluates the impact of DD on metabolic outcomes in individuals treated with GLP-1 RAs. Methods: We conducted a retrospective longitudinal study including 115 patients with T2DM treated with GLP-1 RAs for at least six months. DD was identified based on a documented clinical diagnosis, chronic antidepressant use, or a Beck Depression Inventory (BDI) score ≥16. Metabolic parameters, including glycated hemoglobin (HbA1c), fasting glucose, the body mass index (BMI), the waist circumference, and triglycerides, were compared between patients with and without DD. Results: Patients with DD had significantly higher baseline HbA1c (7.5% vs. 6.9%, p = 0.01), fasting glucose, and triglyceride levels. The waist circumference was also higher in the DD group (p = 0.001). However, no significant differences were observed in weight loss or BMI reductions following the GLP-1 RA treatment. Final HbA1c levels remained higher in the DD group (7.2% vs. 7.0%, p = 0.01). Conclusions: While DD is associated with a poorer baseline metabolic control in T2DM, it does not appear to impair the weight loss efficacy with GLP-1 RAs. However, patients with DD maintain higher post-treatment HbA1c levels, underscoring the need for integrated metabolic and psychiatric care in diabetes management. Full article

Obesity is considered a global pandemic. In Mexico, 7/10 adults, 4/10 adolescents, and 1/3 children are overweight or obese, and it is estimated that 90% of cases of type 2 diabetes (T2D) are attributable to these pathologies. Visceral adipose tissue (VAT) presents increased lipolysis, lower insulin sensitivity, and greater metabolic alterations. Glucagon-like peptide-1 (GLP-1) is a polypeptide incretin hormone that stimulates insulin secretion dependent on the amount of oral glucose consumed, reduces plasma glucagon concentrations, slows gastric emptying, suppresses appetite, improves insulin synthesis and secretion, and increases the sensitivity of β cells to glucose. Liraglutide is a synthetic GLP-1 analog that reduces VAT and improves the expression of Glucose transporter receptor type 4 (GLUT 4R), Mitogen-activated protein (MAP kinases), decreases Fibroblast growth factor type β (TGF-β), reactivates the peroxisome proliferator-activated receptor type ɣ (PPAR-ɣ) pathway, and decreases chronic inflammation. Currently, there are many studies that explain the decrease in VAT with these medications, but there are no studies that compare the decrease in patients with obesity and prediabetes vs. obesity and type 2 diabetes to know which population obtains a greater benefit from treatment with this pharmacological group; this is the reason for this study. The primary objective was to compare the difference in the determination of visceral adipose tissue in people with obesity and type 2 diabetes vs. obesity and prediabetes treated with liraglutide. Methods: A quasi-experimental, analytical, prolective, non-randomized, non-blinded study was conducted over a period of 6 months in a tertiary care center. A total of 36 participants were divided into two arms; group 1 (G1: Obesity and prediabetes) and group 2 (G2: Obesity and type 2 diabetes) for 6 months. Inclusion criteria: men and women ≥18 years with type 2 diabetes, prediabetes, and obesity. Exclusion criteria: Glomerular filtration rate (GFR) < 60 mL/min/1.73 m² elevated transaminases (>5 times the upper limit of normal), and use of non-weight-modifying antidiabetic agents. Conclusions: No statistically significant difference was found in the decrease in visceral adipose tissue when comparing G1 (OB and PD) with G2 (OB and T2D). When comparing intragroup in G2 (OB and T2D), greater weight loss was found [(−3.78 kg; p = 0.012) vs. (−3.78 kg; p = 0.012)], as well differences in waist circumference [(−3.9 cm; p = 0.049) vs. (−3.09 cm; p = 0.017)], and glucose levels [(−1.75 mmol/L; p = 0.002) vs. (−0.56 mmol/L; p = 0.002)], A1c% [(−1.15%; p = 0.001) vs. (−0.5%; p = 0.000)].

Background: Type 2 diabetes mellitus (T2DM) is common among patients with chronic obstructive pulmonary disease (COPD). We examined the association between glycemic control and clinical outcomes in patients with COPD exacerbation and T2DM. Methods: A retrospective study of patients with T2DM and COPD exacerbation comparing controlled (HbA1c < 7.5%) to uncontrolled (HbA1c ≥ 7.5%) glycemia prior to admission. The primary endpoint is defined as a composite of 6-month rehospitalization/mortality. Secondary endpoints included 6-month mortality and 6-month readmission. Results: Of 426 admissions, 179 (42%) had uncontrolled glycemia. The risk of rehospitalization/mortality was significantly increased in the uncontrolled group in univariate (HR1.6, 95%CI 1.11–2.3, p = 0.01) and multivariate (HR 1.82, 95%CI 1.24–2.67, p = 0.002) analyses. The risk of 6-month rehospitalization was increased in the uncontrolled group in both univariate (HR1.94, 95%CI 1.16–3.23, p = 0.011) and multivariate (HR1.98, 95%CI 1.19–3.27, p = 0.008) analyses. No difference was found between 6-month mortality risks. Conclusions: Optimal glycemic control may improve COPD management and reduce adverse outcomes. Full article

Background/Objectives: Hypoglycemia remains the most frequent acute complication of diabetes, particularly among insulin-treated patients, with significant implications for morbidity, length of hospital stay, and healthcare costs. Nurses play a critical frontline role in its recognition and management, yet their competence varies widely. This study aimed to assess the knowledge and attitudes of Croatian nurses regarding hypoglycemia management and to identify key demographic and professional predictors. Methods: We conducted a cross-sectional online survey following CHERRIES guidelines of 317 nurses across Croatia using a validated 26-item knowledge test and a 6-item attitude scale. Descriptive statistics, Mann–Whitney U tests, and standardized effect sizes were used to assess group differences. Multivariable logistic and linear regression models examined the independent effects of education, sex, experience, and workplace setting. Results: The mean knowledge score was 66.9% (SD = 17.8), and the mean attitude score was 3.42 (SD = 0.70) on a 5-point scale. Nurses with tertiary education had significantly higher odds of achieving adequate knowledge (OR = 68.3, 95% CI: 19.9–234.2) and more favorable attitudes (β = +1.02, p < 0.001). Female sex had a small independent effect on knowledge (OR = 2.59, 95% CI: 1.02–6.62), while experience and workplace setting were not significant predictors. Conclusions: Although overall knowledge and attitudes were moderately positive, substantial disparities persist, particularly across educational levels. Clinical Practice Implications: These findings support integrating structured hypoglycemia training into nursing curricula and in-service programs to improve patient safety. Full article

Background/Objectives: DEXCOM™ continuous glucose monitoring devices (DCGMs) have been shown to improve glycaemic control and complication rates in people with Type 1 diabetes (T1DM). However, little qualitative data exists regarding user satisfaction, useful features and the overall lived experience of using a DCGM which will strongly impact one’s quality of life (QOL), compliance and the self-management of diabetes. This study aimed to assess DCGM users’ satisfaction rates and experiences with device features in patients with T1DM in Ireland. Methods: A questionnaire consisting of open- and closed-ended questions together with a glucose monitoring satisfaction survey (GMSS) was offered to all patients attending Sligo University Hospital (SUH) diabetes clinic who used a DCGM for at least six months. Results: Data was analysed for 73 participants. Self-reported QOL improved in 88% of participants and 52% of participants reported fewer hypoglycaemic events. The features most liked by participants were alerts given when the glycaemic target was not in range, improved quality of life, improved hypoglycaemia awareness and the need for reduced finger pricking. However, concerns were also identified about redundant alarms and sensor failures, phone incompatibility and skin reactions. DCGM was associated with good levels of glucose monitoring satisfaction with an overall satisfaction score of 3.67 ± 1.24 out of 5. Participants reported high openness (4.01 ± 0.91), increased trust (3.77 ± 1.16) and low emotional (1.70 ± 0.97) and behavioural burden (2.38 ± 1.10) with DCGM usage. Male participants who had diabetes for a mean duration of 20.06 ± 0.89 years and used DEXCOM^TM for approximately 2 years demonstrated significantly higher levels of satisfaction (p < 0.05). Conclusions: The findings of this study provide a first exploration of patients’ perspectives on DCGM devices in an Irish setting. Results suggest that DCGM users are highly satisfied with the device with an increase in self-reported QOL. Adaptations to features based on patient feedback should be considered to further enhance user satisfaction and maximise QOL benefits. Full article

Introduction: Recent technological progress in optical imaging—such as adaptive optics, interferometry and tomography—has greatly improved the resolution of retinal imaging. The ability to capture sequential images over time is particularly valuable for continuous monitoring and assessment of retinal diseases. Methods: This cross-sectional study involved patients with type 2 diabetes mellitus and age-matched controls from the Diabetes and Ophthalmology Department of the Emergency Military Clinical Hospital “Dr. Constantin Papilian” Cluj-Napoca between October 2023 and October 2024. These patients were assessed for inclusion and exclusion criteria and then categorized into two groups: the diabetes group and control group. Each participant underwent a comprehensive ophthalmological examination and retinal evaluation using SS-OCT (Spectralis Heidelberg Engineering, Heidelberg, Germany). The parameters measured included the superficial and deep foveal avascular zones (FAZ) in only one eye for each patient, selected based on image quality. Additionally, each patient underwent quantitative analysis of serum C-reactive protein (CRP) levels. Results: A total of 33 patients (33 eyes) featured, 13 men and 20 women. The DM group showed statistically significant higher results for CRP value compared to healthy subjects (p < 0.001). Also, both superficial and deep FAZ areas were statistically significantly higher for diabetes patients compared to the healthy controls (p < 0.05). The correlation analysis revealed that there was no significant correlation between CRP and either superficial FAZ (p = 0.809) or deep FAZ (p = 0.659). However, a significant positive moderate correlation was found between superficial FAZ and deep FAZ (r = 0.577, p = 0.015). Conclusions: Our findings showed a significantly enlarged FAZ in diabetic patients compared to healthy individuals, highlighting its potential as an early indicator of microvascular alterations in diabetes. While CRP levels were notably elevated in the diabetic group, no significant association was found between CRP and FAZ measurements, suggesting that FAZ changes may occur independently of systemic inflammatory status.

Background/Objectives: 5-Aminolevulinic acid (5-ALA) is a biosynthetic precursor of heme that induces heme oxygenase-1 (HO-1). Therapeutic induction of HO-1 has shown effectiveness in various autoimmune disease models, including type 1 diabetes (T1D). However, the efficacy of 5-ALA as an HO-1 inducer in T1D models remains unexplored. This study aimed to investigate the therapeutic efficacy of oral 5-ALA administration in preventing autoimmune diabetes development in nonobese diabetic (NOD) mice. Methods: We evaluated diabetes incidence, levels of insulin autoantibody, and severity of insulitis in 5-ALA-treated and control NOD mice. HO-1 expression of dendritic cells in the pancreatic islets and spleen of 5-ALA-treated NOD mice was measured. The IFN-γ/IL-17 of islet-infiltrating T cells and IL-10/IL-12 productions of dendritic cells in the spleen of 5-ALA-treated NOD mice were assessed. We stimulated islet antigen-specific CD4⁺ T cells with islet antigen-pulsed dendritic cells in the presence of 5-ALA and examined the proliferation of the T cells. Finally, we adoptively transferred islet antigen-specific CD4⁺ T cells into 5-ALA-treated, immunodeficient NOD-Rag1 knockout mice, and diabetes incidence in recipients was determined. Results: Oral 5-ALA treatment did not significantly impact diabetes incidence, levels of insulin autoantibody, and insulitis. No significant difference was observed in HO-1 expression in dendritic cells and cytokine production of T cells and dendritic cells. Similarly, there was no significant difference in the proliferation of islet antigen-specific CD4⁺ T cells in vitro and diabetes induction in transfer experiments. Conclusions: Oral administration of 5-ALA has a limited effect on suppressing the development of autoimmune diabetes in NOD mice. Full article
