In a recent article titled "Embracing Cancer Complexity: Hallmarks of Systemic Disease" published in Cell, Swaton et al. propose the idea of cancer as a guest that develops within a host. They discuss the possible causes and events of neoplastic cell dysregulations within an organism, highlighting events such as cachexia and thrombosis. However, we believe that to understand cancer-associated phenomena better, cancer cannot be considered a guest. In reality, cancer is born, develops, and spreads within its environment. It does not come from outside but instead uses the same system in which it lives to promote its death plan. Indeed, today we know that cancer not only causes local symptoms in the affected organ but also leads to systemic symptoms, which are evidence of inflammation associated with cancer. Inflammation is vital in controlling oncogenesis and neoplastic proliferation during the resistance phase, which is a critical moment for the immune system to demonstrate its effectiveness. However, if the immune system causes immunopathological damage, it may lead to necrosis and eventually to the tolerance phase, which can result in systemic symptoms. Understanding these phenomena thoroughly explains thrombophilia, anemia, sarcopenia, and iron metabolism disruption in advanced-stage neoplastic patients. The concept of the microenvironment takes on a different meaning in this context. The same cells that should oppose cancer in the tolerance phase now participate in a process that self-maintains, favoring the growth of the cancer and its death plan. The exact knowledge of these mechanisms is a more modern translational approach to treating cancer and its related symptoms., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024.

Potassium is the most represented intracellular electrolyte in the human body. Its extracellular levels are maintained within strict limits through different mechanisms, which constitute the homeostasis of potassium. Hyperkalemia is the most common electrolyte disorder in patients with cardiovascular disease. Although with different levels of severity, it carries an increased risk of hospitalization, cardiovascular morbidity and mortality. Hyperkalemia may also be an important cause of discontinuation or impossibility of titration of fundamental therapies in the cardiology patient. The principal aim of this review is to analyze the mechanisms underlying hyperkalemia, as well as to summarize its epidemiology, risk factors, monitoring methodologies and electrophysiological and electrocardiographic effects, providing just only few essential elements of therapy. In this way the physician, and especially the cardiologist, can have an adequate knowledge for its management in clinical practice.

Background and Aim: Suboptimal disease control (SDC) and its contributing factors in IBD according to STRIDE-II criteria is unclear. IBD-PODCAST was a non-interventional, international, multicenter real-world study to assess this., Methods: Data from the Italian IBD cohort (N=220) are presented here. Participants aged ≥19 with confirmed IBD diagnosis of ≥1 year were consecutively enrolled. A retrospective chart review and cross-sectional assessment by physicians and patients within the past 12 months were performed. SDC or optimal disease control was assessed using adapted STRIDE-II criteria., Results: At the index date, 53.4 % of 116 CD patients and 49.0 % of 104 UC patients had SDC, mainly attributed to a Short Inflammatory Bowel Disease Questionnaire score <50, failure to achieve endoscopic remission, and the presence of active extra-intestinal manifestations in both diseases. Disease monitoring with imaging and/or endoscopy during the previous year was conducted in ∼50 % of patients, with endoscopy performed in ∼40 %. Potential therapeutic adjustments were reported for half of the patients., Conclusions: This study highlights SDC in a significant portion of IBD Italian patients. These results emphasize the need for more proactive management strategies in both CD and UC patients., Competing Interests: Competing interests, (Copyright © 2024. Published by Elsevier Ltd.)
