Pancreatic ductal adenocarcinoma (PDAC) ranks among the 15 most prevalent cancers globally, characterized by aggressive growth and late-stage diagnosis. Advances in imaging and surgical techniques have redefined the classification of pancreatic PDAC into resectable, borderline resectable, and locally advanced pancreatic cancer. While surgery remains the most effective treatment, only 20% of patients are eligible at diagnosis, necessitating innovative strategies to improve outcomes. Therefore, traditional treatment paradigms, primarily surgical resection for eligible patients, are increasingly supplemented by neoadjuvant therapies (NAT), which include chemotherapy, radiotherapy, or a combination of both. By administering systemic therapy prior to surgery, NAT aims to reduce tumor size and increase the feasibility of complete surgical resection, thus enhancing overall survival rates and potentially allowing more patients to undergo curative surgeries. Recent advances in treatment protocols, such as FOLFIRINOX and gemcitabine-nab-paclitaxel, now integral to NAT strategies, have shown promising results in increasing the proportion of patients eligible for surgery by effectively reducing tumor size and addressing micrometastatic disease. Additionally, they offer improved response rates and survival benefits compared to traditional regimes. Despite these advancements, the role of NAT continues to evolve, necessitating ongoing research to optimize treatment regimens, minimize adverse effects, and identify patient populations that would benefit most from these approaches. Through a detailed analysis of current literature and recent clinical trials, this review highlights the transformative potential of NAT in managing PDAC, especially in patients with borderline resectable or locally advanced stages, promising a shift towards more personalized and effective management strategies for PDAC.

Heart failure (HF) is a growing public health concern, driven by the increasing prevalence of obesity, diabetes, and aging. Despite therapeutic advances, HF continues to be associated with high morbidity and mortality. Glucagon-like peptide-1 receptor agonists (GLP-1 RAs), originally developed for glycemic control in type 2 diabetes, have demonstrated cardiovascular benefits in clinical trials. Recent studies, including STEP-HFpEF and SUMMIT, have shown improvement in symptoms and weight loss in patients with HF with preserved ejection fraction (HFpEF). GLP-1 RAs are involved in multiple biological pathways relevant to heart failure pathophysiology. These include pathways related to sympathetic nervous system activity, inflammatory cytokine signaling, oxidative stress, calcium handling, natriuretic peptide signaling, and cardiac metabolism. GLP-1 receptor agonists modulate vascular pathways involving nitric oxide signaling, endothelial function, and renal sodium handling, contributing to improved hemodynamics and neurohormonal balance. Together, these actions intersect with key neurohormonal and cellular processes contributing to chronic heart failure progression. This review explores the mechanistic overlap between GLP-1 receptor signaling and heart failure pathophysiology. This mechanistic overlap suggests a plausible role for these agents as adjunctive treatments in heart failure, especially in metabolically driven phenotypes. While direct cardiac effects remain incompletely defined, systemic metabolic and anti-inflammatory actions provide a mechanistic basis for observed clinical benefits.

Background/Objectives: Cognitive impairment is a debilitating comorbidity affecting diverse patient populations, yet the cognitive effects of therapies like mineralocorticoid receptor antagonists (MRAs) remain underexplored. Preclinical evidence suggests that MRAs, particularly spironolactone, may reduce cognitive decline by modulating aldosterone-dependent pathways and targeting hippocampal receptors. However, evidence in humans is fragmented, and no systematic review has consolidated these findings. This review evaluates the cognitive effects of MRAs, synthesizes current data, and identifies research gaps. Methods: A literature search using terms related to MRAs and cognitive outcomes was performed in PubMed and Web of Science from 1979 to 2023. A total of 143 articles were identified and 85 were screened after removing duplicates. Ultimately, 44 studies were included and were classified based on study design and population focus (preclinical, healthy controls, patients with psychiatric disorders, and cardiovascular patients). Results: Spironolactone demonstrated mixed effects on cognition. In healthy participants, it improved spatial memory under stress and prevented stress-related suppression of medial temporal activity, but impaired working memory and selective attention. In patients with psychiatric conditions, spironolactone reduced cognitive empathy deficits in major depressive disorder and improved working memory in bipolar I disorder. In cardiovascular patients, spironolactone improved cognitive scores and hippocampal memory but had no effect on non-hippocampal memory. Conclusions: Spironolactone exhibits potential cognitive benefits across diverse populations. However, its effects on cognition are mixed, highlighting the need for further research to understand its mechanisms and therapeutic potential, particularly in patients with heart failure and other related conditions.

Vitamin D is a key regulator of calcium and phosphorus homeostasis; meanwhile, the dietary absence of vitamin D represents the most common nutritional deficiency worldwide. The discovery of vitamin D receptors and conversion enzymes within the cardiovascular system has fueled growing interest in the potential roles of vitamin D beyond bone health. Indeed, preclinical studies have suggested that vitamin D might regulate vascular tone and exert antifibrotic and anti-remodeling effects on the myocardium. Furthermore, a deficit in vitamin D has been associated with an increased risk of hypertension, atherosclerosis, and heart failure. These findings have prompted several interventional studies to investigate whether vitamin D supplementation can mitigate cardiovascular risk. However, current evidence regarding the cardiovascular benefits of vitamin D intake remains inconsistent and inconclusive. This review aims to provide a comprehensive overview of the “good”, the “bad”, and the “unknown” aspects of the relationship between vitamin D and cardiovascular disease.

Background: Detection of myocardial bridge (MB) at angiography suggests it has a role in ischaemic-related symptoms in patients with angina without obstructive coronary artery disease. However, evidence that MB may cause myocardial ischaemia is limited. Methods: We studied 41 patients with MB of the left anterior descending coronary artery and otherwise normal coronary arteries. Fourteen patients with normal coronary arteries and without MB served as controls. All subjects underwent a maximal treadmill exercise stress test (EST) under ECG monitoring. Standard and speckle-tracking echocardiography were performed at baseline and immediately after peak EST. Results: EST duration and peak heart rate and systolic pressure were similar in the two groups. A positive EST (ST-segment depression ≥1 mm) was found in 18 patients in the MB group (43.9%) and none in the control group (p=0.001). No abnormalities in both left ventricle systolic and diastolic function were found between the two groups in the standard echocardiographic evaluation. Global and segmental (anterior, inferior) longitudinal strain (LS) did not differ at baseline between the groups. There was a small increase in global LS during EST in MB patients but not in the control group (p=0.01). Similar trends were found for regional LSs, with differences being significant for the medium (p=0.028) and apical (p=0.032) anterior segments. No differences in echocardiographic parameters and both global and segmental LSs were observed between MB patients with ischaemic ECG changes during EST versus those without. Conclusion: Our findings do not support the notion that MB results in significant degrees of myocardial ischaemia during maximal myocardial work.
