Dementia is an age-related syndrome characterized by the progressive deterioration of cognition and capacity for independent living. Diabetes is often associated with cognitive decline and shares similar pathophysiological mechanisms with dementia, such as systemic inflammation, oxidative stress, insulin resistance, and advanced glycation end-products formation. Therefore, adequate diabetes management may reduce the risk of cognitive decline, especially in patients with other comorbidities and risk factors. The sodium glucose cotransporter inhibitors (SGLT2i) regulate renal glucose reabsorption by blocking the SGLT2 cotransporters located in the proximal tubules, causing glycosuria and intraglomerular pressure reduction. Their use helps to lower blood pressure by modifying sodium and water homeostasis; these drugs are also commonly used in the treatment of heart failure and chronic kidney disease, while recently, a potential neuroprotective role in the central nervous system has been suggested. The aim of our scoping review is to analyze current evidence about the potential neuroprotective effects of SGLT2i in adult patients. We performed a scoping literature review to evaluate the effect of SGLT2i on dementia, mild cognitive impairment (MCI) and Alzheimer’s disease incidence and progression. The screening process was performed through different searches on PubMed and EMBASE, evaluating original works published up to January 2024. In conclusion, the use of SGLT2i could be associated with a neuroprotective effect in patients with diabetes, reducing the incidence or the progression of MCI and dementia. Further prospective studies are needed to validate this hypothesis and to evaluate the effectiveness of this class of drugs in normal glycemic profile patients.

Patients with Noonan syndrome typically have a target height <2 standard deviations compared to the general population, and half of the affected adults remain permanently below the 3rd centile for height, though their short stature might result from a multifactorial etiology, not-yet fully understood. The secretion of growth hormone (GH) following the classic GH stimulation tests is often normal, with baseline insulin-like growth factor-1 (IGF-1) levels at the lower normal limits, but patients with Noonan syndrome have also a possible moderate response to GH therapy, leading to a final increased height and substantial improvement in growth rate. Aim of this review was to evaluate both safety and efficacy of GH therapy in children and adolescents with Noonan syndrome, also evaluating as a secondary aim the possible correlations between the underlying genetic mutations and GH responses.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the virus responsible for the pandemic viral pneumonia that was first identified in Wuhan, China, in December 2019, and has since rapidly spread around the world. The number of COVID-19 cases recorded in pediatric age is around 1% of the total. The immunological mechanisms that lead to a lower susceptibility or severity of pediatric patients are not entirely clear. At the same time, the immune dysregulation found in those children who developed the multisystem inflammatory syndrome (MIC-S) is not yet fully understood. The aim of this review is to analyze the possible influence of children’s innate immune systems, considering the risk of contracting the virus, spreading it, and developing symptomatic disease or complications related to infection.

Background and Objectives: Despite major advances in medical science and critical care, sepsis remains a leading cause of morbidity and mortality worldwide: it arises from dysregulated host response to infections and may culminate in organ dysfunction. A hallmark of its pathogenesis is the cytokine storm, in which interleukins (ILs) serve as central mediators of both protective and deleterious immune responses. This review summarizes the current knowledge on the role of ILs in sepsis, emphasizing their potential as biomarkers and therapeutic targets. Material and Methods: We analyzed recent clinical and experimental studies focusing on the most studied ILs—including IL-1, IL-6, IL-10, IL-8, IL-12, IL-18, and IL-17—in the pathophysiology of sepsis. Attention was given to mechanistic insights, prognostic significance, and therapeutic strategies targeting IL pathways. Results: IL-1 and IL-6 emerged as key pro-inflammatory mediators, amplifying vascular permeability, coagulation activation, and shock, with IL-6 validated as a robust prognostic biomarker. IL-10 was identified as a pivotal anti-inflammatory cytokine, limiting tissue injury but fostering immunosuppression and secondary infections. Other ILs, such as IL-8, IL-12, IL-18, and IL-17, contributed to neutrophil recruitment, Th1/Th17 activation, organ-specific injury, and sepsis susceptibility. Therapeutic interventions targeting ILs, including the IL-1 receptor antagonist anakinra and IL-6 receptor blockade with tocilizumab, have shown promise in selected patient subgroups. Conclusions: ILs are central to the immunopathology of sepsis, acting both as drivers of hyperinflammation and mediators of immunosuppression. Their dual role underscores the relevance of ILs as diagnostic and prognostic biomarkers, as well as context-dependent therapeutic targets. Future approaches should prioritize precision immunomodulation aligned with the principles of personalized medicine to improve clinical outcomes in sepsis.

Background: Individuals with hyperinsulinemia may initially not meet any diagnostic criteria for metabolic syndrome, though displaying a higher risk of cardiovascular complications combined with obesity, diabetes, and hypertension. Aim: The main objective of our study was to assess the diagnostic accuracy of various cardiovascular risk indices in hyperinsulinemic children and adolescents; a secondary objective was to estimate the optimal cut-offs of these indices. Patients and methods: This retrospective single-center study was conducted on 139 patients aged 12.1 ± 2.9 years, managed for hyperinsulinism. Results: We found statistically significant differences in homeostasis model assessment of insulin resistance index (HOMA-IR), triglyceride glucose index (TyG), TyG-body mass index, visceral adiposity index, lipid accumulation product index, fatty liver index, and hepatic steatosis index. At the linear logistic regression assessment, we found that insulin growth factor-1 (IGF-1), HOMA-IR, and ALT/AST ratio were independently associated with confirmed hyperinsulinism. At the multivariate analysis, IGF-1 levels over 203 ng/mL and HOMA-IR higher than 6.2 were respectively associated with a 9- and 18-times higher odds ratio for hyperinsulinism. The other investigated parameters were not significantly related to hyperinsulinism, and could not predict either the presence of hyperinsulinemia or a subsequent cardiovascular risk in our patients. Conclusion: Commonly used indices of cardiovascular risk in adults cannot be considered accurate in confirming hyperinsulinism in children, with the exception of HOMA-IR. Further studies are needed to verify the usefulness of specific cardiovascular risk indices in hyperinsulinemic children and adolescents.
