Cancer patients, especially long cancer survivors, are exposed to several cardio-metabolic diseases, including diabetes, heart failure, and atherosclerosis, which increase their risk of cardiovascular mortality. Therapy with glucagon-like peptide 1 (GLP1) receptor agonists demonstrated several beneficial cardiovascular effects, including atherosclerosis and heart failure prevention. Cardiovascular outcome trials (CVOTs) suggest that GLP-1 RA could exert cardiorenal benefits and systemic anti-inflammatory effects in patients with type-2 diabetes through the activation of cAMP and PI3K/AkT pathways and the inhibition of NLRP-3 and MyD88. In this narrative review, we highlight the biochemical properties of GLP-1 RA through a deep analysis of the clinical and preclinical evidence of the primary prevention of cardiomyopathies. The overall picture of this review encourages the study of GLP-1 RA in cancer patients with type-2 diabetes, as a potential primary prevention strategy against heart failure and atherosclerosis.

Mindfulness-based stress reduction, a complementary and alternative therapy, is able to decrease cancer-related fatigue, and stress and to improve the quality of life in cancer patients. Some studies evaluated if mindfulness-based stress reduction could improve some cardiometabolic and cancer risk factors, including systemic chemokines, growth factors, and pro-inflammatory biomarkers (e.g., C-reactive protein, Interleukin-1). In this narrative review, we highlight the pleiotropic beneficial effects of mindfulness-based stress reduction and its clinical impact on cardiovascular and cancer risk factors among patients with cancer in different stages. Moreover, improvements in the overall quality of life, sleep quality, and immune functions [changes in plasma levels of interleukin-4 (IL-4), interferon-γ (INF-γ), and interleukin-10 (IL-10)] will also be discussed. Albeit few clinical studies available in the literature, evidenced the beneficial effects of mindfulness-based stress reduction on the immune and cardiometabolic profile in cancer patients, providing important insights into the closest collaboration between psycho-oncologists, oncologists, and cardiologists.

In cancer therapy, stimulus-responsive drug delivery systems are of particular interest for reducing side effects in healthy tissues and improving drug selectivity in the tumoral ones. Here, a strategy for the preparation of a photo-responsive cross-linked trilayer deposited onto an oil-in-water nanoemulsion via a layer-by-layer technique is reported. The system is made of completely biocompatible materials such as soybean oil, egg lecithin and glycol chitosan, with heparin as the polymeric shell. The oil core is pre-loaded with curcumin as a model lipophilic active molecule with anti-tumoral properties. The trilayer cross-linkage is performed via a photoinitiator-free thiol-ene 'click' reaction. In particular, the system is implemented with an o -nitrobenzyl group functionalized with a thiol moiety which can perform both the thiol-ene 'click' reaction and the cleavage meant for controlled drug release at two different wavelengths, respectively. So the preparation and characterization of a photo-responsive natural nanocarrier (PNC) that is stable under physiological conditions owing to the thiol-ene cross-linkage are reported. PNC performance has been assessed in vitro on melanoma cells as well as in vivo on xenograft tumour-induced mice.

Hyaluronic acid (HA)-based prodrugs bearing double-responsive (acid pH or oxidation) boronates of catechol-containing drugs were used to treat xenografted human prostate tumours (LNCaP) in SCID mice. The HA prodrugs accumulated significantly only in tumours (impressively, up to 40% of the injected dose after 24 h) and in liver, with negligible - actually anti-inflammatory - consequences in the latter. A quercetin-HA prodrug significantly slowed down tumour growth, in a dose-dependent fashion and with a much higher efficacy (up to 4 times) than equivalent doses of free quercetin. In short, boronated HA appears to be a very promising platform for targeted chemotherapy., (Copyright © 2021 The Authors. Published by Elsevier B.V. All rights reserved.)

Cytokines in cardiac tissue plays a key role in progression of cardiometabolic diseases and cardiotoxicity induced by several anticancer drugs. Interleukin-1β is one on the most studied regulator of cancer progression, survival and resistance to anticancer treatments. Recent findings indicate that interleukin1-β exacerbates myocardial damages in cancer patients treated with chemotherapies and immune check-point inhibitors. Interleukin1-β blocking agent canakinumab reduces major adverse cardiovascular events and cardiovascular death in recent cardiovascular trials. We focalized on the main biological functions of interleukin1-β in cancer and cardiovascular diseases, summarizing the main clinical evidence available to date in literature. Especially in the era of SARS-CoV-2 infection, associated to coagulopathies, myocarditis and heart failure, cancer patients have an increased risk of cardiovascular complications compared to general population, therefore, the pharmacological inhibition of interleukin1-β should be discussed and considered.

The COVID-19 pandemic and its impact on patients with cancer and cardiovascular disease have confirmed the particular vulnerability of this population. Indeed, not only a higher risk of contracting the infection has been reported, but also an increased occurrence of a more severe course and unfavorable outcome. Beyond the direct consequences of COVID-19, the pandemic has an enormous impact on global health systems. Screening programs and non-urgent tests have been postponed; clinical trials have suffered a setback. Similarly, in the area of cardiology care, a significant decline in ST-elevation myocardial infarction accesses and an increase in cases of late presenting heart attacks with increased mortality and complication rates have been reported. Health care systems must therefore get ready to tackle the "rebound effect" that will likely show a relative increase in the short and medium term incidence of diseases such as heart failure, myocardial infarction, arrhythmias and cardio- and cerebrovascular complications. Scientific societies are taking action to provide general guidance and recommendations aimed at mitigating the unfavorable outcomes of this pandemic emergency. Cardio-oncology, as an emerging discipline, is more flexible in modulating care pathways and represents a beacon of innovation in the development of multi-specialty patient management. In the era of the COVID-19 pandemic, cardio-oncology has rapidly modified its clinical care pathways and implemented flexible monitoring protocols that include targeted use of cardiac imaging, increased use of biomarkers, and telemedicine systems. The goal of these strategic adjustments is to minimize the risk of infection for providers and patients while maintaining standards of care for the treatment of oncologic and cardiovascular diseases. The aim of this position paper is to evaluate the impact of the COVID-19 pandemic on the management of cardio-oncologic patients with the-state-of-the-art knowledge about SARS-CoV-2 and COVID-19 in order to optimize medical strategies during and after the pandemic.

Abstract: Many antitumoral drugs have been linked to takotsubo cardiomyopathy, with no clear pathogenetic mechanisms. Data about this condition are lacking in literature. The aim of this meta-summary is to summarize the characteristics of patients with antitumoral drug-induced takotsubo cardiomyopathy, described in case reports available in literature. We searched for published case reports in PubMed, Google Scholar, EMBASE, and Scopus from 2009 about stress cardiomyopathy and antiblastic drugs. We selected 41 case reports. All cases underwent chemotherapy/immunotherapy for different types of cancer. The median age was 58 years, and 61% of them were women. The most common comorbidities were hypertension (12.2%) and dyslipidemia (4.9%), but most of the population had no cardiological clinical history. Takotsubo cardiomyopathy is associated to the 5-fluorouracil (36.5%), capecitabine (9.7%), trastuzumab (9.7%), and immune check point inhibitor (9.7%) treatment. The median time of onset was 2 days (1-150). Cardiogenic shock was the first manifestation in 11 patients (26.8%). Left ventricle ejection fraction recovery was showed in 33 patients (89%) with mean ejection fraction 57.7 ± 7%, after a median of 30-day (4-300) follow-up. Patients with cancer experienced takotsubo cardiomyopathy within few days from the beginning of therapy, and the most of them normalized the heart function in few weeks. Cardiogenic shock showed high prevalence in this setting of patients. Larger studies are needed to better understand the pathological mechanisms of antiblastic drug-induced stress cardiomyopathy, to find risk factors associated and preventive strategies for limit this type of cardiotoxicities., Competing Interests: The authors report no conflicts of interest., (Copyright © 2021 Wolters Kluwer Health, Inc.

The World Cancer Research Fund and American Institute for Cancer Research (WCRF/AICR) advise cancer survivors to follow their lifestyle recommendations for cancer prevention.  Recent research indicates that a proper diet could exerts beneficial metabolic and immune effects in humans through the involvement of several, not yet properly known, metabolic pathways. Here, we argue that following WCRF/AICR recommendations could be a strategy to prevent cardiovascular outcomes [fulminant myocarditis, heart failure, venous thromboembolism (VTE)] and acute respiratory distress syndrome (ARDS) in patients during follow-up post COVID-19 infection. We discuss the metabolic effects of a WCRF/AICR based diet, highlighting on the involved cardio-metabolic pathways related on NLRP3 inflammasome-cytokines axis aimed to improve prognosis of COVID-19, especially in patients with cancer.

Resveratrol (3,5,4'-trihydroxystilbene) is a natural phytoalexin that accumulates in several vegetables and fruits like nuts, grapes, apples, red fruits, black olives, capers, red rice as well as red wines. Being both an extremely reactive molecule and capable to interact with cytoplasmic and nuclear proteins in human cells, resveratrol has been studied over the years as complementary and alternative medicine (CAM) for the therapy of cancer, metabolic and cardiovascular diseases like myocardial ischemia, myocarditis, cardiac hypertrophy and heart failure. This review will describe the main biological targets, cardiovascular outcomes, physico-chemical and pharmacokinetic properties of resveratrol in preclinical and clinical models implementing its potential use in cancer patients.

Introduction: Complementary and Alternative Medicine (CAM) include a wide range of products (herbs, vitamins, minerals, and probiotics) and medical practices, developed outside of the mainstream Western medicine. Patients with cancer are more likely to resort to CAM first or then in their disease history; the potential side effects as well as the costs of such practices are largely underestimated., Patients and Method: We conducted a descriptive survey in five Italian hospitals involving 468 patients with different malignancies. The survey consisted of a forty-two question questionnaire, patients were eligible if they were Italian-speaking and receiving an anticancer treatment at the time of the survey or had received an anticancer treatment no more than three years before participating in the survey., Results: Of our patients, 48.9% said they use or have recently used CAM. The univariate analysis showed that female gender, high education, receiving treatment in a highly specialized institute and receiving chemotherapy are associated with CAM use; at the multivariate analysis high education (Odds Ratio, (OR): 1.96 95% Confidence Interval, CI, 1.27-3.05) and receiving treatment in a specialized cancer center (OR: 2.75 95% CI, 1.53-4.94) were confirmed as risk factors for CAM use., Conclusion: Roughly half of our patients receiving treatment for cancer use CAM. It is necessary that health professional explore the use of CAM with their cancer patients, educate them about potentially beneficial therapies in light of the limited available evidence of effectiveness, and work towards an integrated model of health-care provision.
