ABSTRACT

Cancer-associated thrombosis (CAT) is a leading cause of death among patients with cancer. CAT can manifest itself as venous thromboembolism (VTE), in the form of deep vein thrombosis or pulmonary embolism, or arterial thromboembolism. The pathophysiology of CAT is complex and depends on cancer-, patient-, treatment- and biomarkers-related factors. Treatment of VTE in patients with cancer is complex and includes three major classes of anticoagulant agents: heparin and its derivatives, e.g., low molecular weight heparins, direct oral anticoagulants (DOACs), and vitamin K inhibitors. Given the tremendous heterogeneity of clinical situations in patients with cancer and the challenges of CAT, there is no single universal treatment option for patients suffering from or at risk of CAT. Initial studies suggested that patients seemed to prefer an anticoagulant that would not interfere with their cancer treatment, suggesting the primacy of cancer over VTE, and favoring efficacy and safety over convenience of route of administration. Recent studies show that when the efficacy and safety aspects are similar, patients prefer the oral route of administration. Despite this, injectables are a valid option for many patients with cancer.

Development and Validation of a Nomogram Model for the Risk of Cardiac Death in Patients Treated with Chemotherapy for Esophageal Cancer

Cardiovasc Toxicol. 2023 Oct 7. doi: 10.1007/s12012-023-09807-4. Online ahead of print.

ABSTRACT

The primary cause of mortality in esophageal cancer survivors is cardiac death. Early identification of cardiac mortality risk during chemotherapy for esophageal cancer is crucial for improving the prognosis. We developed and validated a nomogram model to identify patients with high cardiac mortality risk after chemotherapy for esophageal cancer for early screening and clinical decision-making. We randomly allocated 37,994 patients with chemotherapy-treated esophageal cancer into two groups using a 7:3 split ratio: model training (n = 26,598) and validation (n = 11,396). 5- and 10-year survival rates were used as endpoints for model training and validation. Decision curve analysis and the consistency index (C-index) were used to evaluate the model's net clinical advantage. Model performance was evaluated using receiver operating characteristic curves and computing the area under the curve (AUC). Kaplan-Meier survival analysis based on the prognostic index was performed. Patient risk was stratified according to the death probability. Age, surgery, sex, and year were most closely related to cardiac death and used to plot the nomograms. The C-index for the training and validation datasets were 0.669 and 0.698, respectively, indicating the nomogram's net clinical advantage in predicting cardiac death risk at 5 and 10 years. The 5- and 10-year AUCs were 0.753 and 0.772 for the training dataset and 0.778 and 0.789 for the validation dataset, respectively. The accuracy of the model in predicting cardiac death risk was moderate. This nomogram can identify patients at risk of cardiac death after chemotherapy for esophageal cancer at an early stage.

Advances in Screening for Radiation-Associated Cardiotoxicity in Cancer Patients

Curr Cardiol Rep. 2023 Oct 5. doi: 10.1007/s11886-023-01971-x. Online ahead of print.

ABSTRACT

PURPOSE OF REVIEW: Radiation is foundational to the treatment of cancer and improves overall survival. Yet, it is important to recognize the potential cardiovascular effects of radiation therapy and how to best minimize or manage them. Screening-both through imaging and with biomarkers-can potentially identify cardiovascular effects early, allowing for prompt initiation of treatment to mitigate late effects.

RECENT FINDINGS: Cardiac echocardiography, magnetic resonance imaging (MRI), computed tomography, and measurements of troponin and natriuretic peptides serve as the initial screening tests of choice for RICD. Novel imaging applications, including positron emission tomography and specific MRI parameters, and biomarker testing, including myeloperoxidase, growth differentiation factor 15, galectin 3, micro-RNA, and metabolomics, hold promise for earlier detection and more specific characterization of RICD. Advances in imaging and novel applications of biomarkers have potential to identify subclinical RICD and may reveal opportunities for early intervention. Further research is needed to elucidate optimal imaging screening modalities, biomarkers, and surveillance strategies.

Anti-Inflammatory and Anticancer Effects of Anticoagulant Therapy in Patients with Malignancy

Life (Basel). 2023 Sep 10;13(9):1888. doi: 10.3390/life13091888.

ABSTRACT

Optimizing the anticoagulation therapy is of pivotal importance in patients with a malignant tumor, as venous thromboembolism (VTE) has become the second-leading cause of death in this population. Cancer can highly increase the risk of thrombosis and bleeding. Consequently, the management of cancer-associated VTE is complex. In recent years, translational research has intensified, and several studies have highlighted the role of inflammatory cytokines in cancer growth and progression. Simultaneously, the pleiotropic effects of anticoagulants currently recommended for VTE have emerged. In this review, we describe the anti-inflammatory and anticancer effects of both direct oral anticoagulants (DOACs) and low-molecular-weight heparins (LWMHs).

The Risk of Thromboembolism in Patients with Muscle Invasive Bladder Cancer before and after Cystectomy Depending on Blood Group and Neoadjuvant Chemotherapy-A Multicentre Retrospective Cohort Study

J Pers Med. 2023 Sep 4;13(9):1355. doi: 10.3390/jpm13091355.

ABSTRACT

PURPOSE: Previous studies have indicated that patients with muscle-invasive bladder cancer with non-O blood types have an increased risk of experiencing thromboembolic events (TEEs). This is finding is in relation to neoadjuvant-chemotherapy (NAC)-naïve patients.

AIM: to establish the risk of TEEs and any association with blood types among NAC patients as well as NAC-naïve patients.

METHODS: Cystectomized patients at four centres treated from 2009 to 2018 (n = 244) were analysed. The quantities of patients corresponding to each blood group were as follows: A-108 (44%); O-99 (41%); B-30 (12%); and AB-7 (3%). NAC patients (n = 167) and NAC-naïve NAC-eligible patients (n = 77) were assessed. In total, 54 women (22%) and 190 men (78%), with a median age of 69 years, were included in the study. The occurrence of any type of TEE from six months pre-cystectomy to 12-24 months after was analysed using logistic regression adjusted for NAC and confounders.

RESULTS: Sixty-six TEEs were detected in 21% of the patients (n = 52). Pulmonary embolus (n = 33) and deep venous thrombosis (n = 11) were the most common forms. No significant differences between blood types were found in the analysis, although B blood type had a nearly significant increased crude risk compared with O blood type, for which there was an OR of 2.48 (95% CI 0.98-6.36). Adjustment for NAC and covariates weakened the OR, which plummeted to 1.98 (95% CI 0.71-5.51).

CONCLUSIONS: No significant associations were found between blood types and TEE occurrences in this cohort including both NAC and NAC-naïve NAC-eligible patients.

Survey on the Knowledge and Management of Cancer-Associated Thrombosis (CAT) in Haemato-Oncology Patients with Thrombocytopenia among Haematologists and Haematology Residents in Nigeria

West Afr J Med. 2023 Sep 28;40(9):956-961.

ABSTRACT

BACKGROUND: Arterial or venous thrombosis can complicate cancer, and 20% of cancer patients may develop venous thromboembolic disorders. Venous thromboembolism (VTE) is common in some haematologic malignancies and may coexist with thrombocytopenia in those haematologic malignancies. We carried out this survey to assess the knowledge and practice of haematologists and resident doctors in haematology in Nigeria regarding the management of thrombocytopenia and cancer-associated thrombosis.

METHODS: This was a survey that was shared electronically with participants who were consultant haematologists and resident doctors in haematology in Nigeria..

RESULTS: There were 106 respondents, 70 (66%) of which were consultant haematologists. About a third (30.2%) of the respondents saw 6-10 patients with blood malignancies monthly. Fifty-seven (53.8%) of the respondents carried out risk assessment in their patients for cancer-associated thrombosis (CAT); 63 (59.4%) of the respondents saw 1-2 cancer patients with thrombosis in 3 months. The most common mode of treatment was pharmacological - 94 (88%) respondents used low molecular weight heparin. The most common haematologic malignancies associated with thrombocytopenia were acute leukaemias (69; 67%). The most common decision taken by respondents was to stop anticoagulants and transfuse platelets because the most frequent concern was the risk of bleeding in this group of patients.

CONCLUSION: Many haematologists and haematology residents had a high level of awareness, knowledge and good practice regarding thrombocytopenia with CAT in haematooncology patients; however, there is a need for improved knowledge and unified protocols for treatment in line with newer management guidelines.

ReLiFiRa (Real Life Filgotinib in Rheumatoid Arthritis): Retrospective Study of Efficacy and Safety in Common Clinical Practice

J Pers Med. 2023 Aug 25;13(9):1303. doi: 10.3390/jpm13091303.

ABSTRACT

BACKGROUND: Filgotinib (FIL) is a selective JAK1 inhibitor with an affinity 30-fold higher than JAK2, approved to treat moderate to severe active rheumatoid arthritis (RA), in adults with inadequate response or intolerance to one or more disease-modifying antirheumatic drugs (DMARDs).

METHODS: We conducted a retrospective, multicentric study in order to evaluate efficacy and safety of FIL 200 mg daily therapy, after 3 and 6 months, in 120 patients affected by RA, managed in Tuscany and Umbria rheumatological centers. The following clinical records were analyzed: demographical data, smoking status, previous presence of comorbidities (Herpes zoster -HZ- infection, venous thromboembolism -VTE-, major adverse cardiovascular events -MACE-, cancer, diabetes, and hypertension), disease duration, presence of anti-citrullinated protein antibodies (ACPA), rheumatoid factor (RF), number of biological failures, and prior csDMARDs utilized. At baseline, and after 3 (T3) and 6 (T6) months of FIL therapy, we evaluated mean steroid dosage, csDMARDs intake, clinimetric indexes (DAS28, CDAI, HAQ, patient and doctor PGA, VAS), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and body mass index (BMI).

RESULTS: At baseline, the mean disease duration was 9.4 ± 7.5 years; the prevalence of previous HZ infection, VTE, MACE, and cancer was respectively 4.12%, 0%, 7.21%, and 0.83%, respectively. In total, 76.3% of patients failed one or more biologics (one biological failure, 20.6%; two biological failures, 27.8%; three biological failures, 16.5%; four biological failures, 10.3%; five biological failures, 1.1%). After 3 months of FIL therapy, all clinimetric index results significantly improved from baseline, as well as after 6 months. Also, ESR and CRP significatively decreased at T3 and T6. Two cases of HZ were recorded, while no new MACE, VTE, or cancer were recorded during the observation time.

CONCLUSION: Despite the limitations of the retrospective study and of the observational period of only 6 months, real-life data on the treatment of RA patients with FIL demonstrate that this Jak inhibitor therapy is safe in terms of CV, VTE events, and occurrence of cancer, and is also effective in a population identified as "difficult to treat" due to failure of previous b-DMARD therapy.

Outcomes of patients with active cancers and pre-existing cardiovascular diseases infected with SARS-CoV-2

Cardiooncology. 2023 Oct 6;9(1):36. doi: 10.1186/s40959-023-00187-w.

ABSTRACT

OBJECTIVE: To determine the impact of acute SARS-CoV-2 infection on patient with concomitant active cancer and CVD.

METHODS: The researchers extracted and analyzed data from the National COVID Cohort Collaborative (N3C) database between January 1, 2020, and July 22, 2022. They included only patients with acute SARS-CoV-2 infection, defined as a positive test by PCR 21 days before and 5 days after the day of index hospitalization. Active cancers were defined as last cancer drug administered within 30 days of index admission. The "Cardioonc" group consisted of patients with CVD and active cancers. The cohort was divided into four groups: (1) CVD (-), (2) CVD ( +), (3) Cardioonc (-), and (4) Cardioonc ( +), where (-) or ( +) denotes acute SARS-CoV-2 infection status. The primary outcome of the study was major adverse cardiovascular events (MACE), including acute stroke, acute heart failure, myocardial infarction, or all-cause mortality. The researchers analyzed the outcomes by different phases of the pandemic and performed competing-risk analysis for other MACE components and death as a competing event.

RESULTS: The study analyzed 418,306 patients, of which 74%, 10%, 15.7%, and 0.3% had CVD (-), CVD ( +), Cardioonc (-), and Cardioonc ( +), respectively. The Cardioonc ( +) group had the highest MACE events in all four phases of the pandemic. Compared to CVD (-), the Cardioonc ( +) group had an odds ratio of 1.66 for MACE. However, during the Omicron era, there was a statistically significant increased risk for MACE in the Cardioonc ( +) group compared to CVD (-). Competing risk analysis showed that all-cause mortality was significantly higher in the Cardioonc ( +) group and limited other MACE events from occurring. When the researchers identified specific cancer types, patients with colon cancer had higher MACE.

CONCLUSION: In conclusion, the study found that patients with both CVD and active cancer suffered relatively worse outcomes when they had acute SARS-CoV-2 infection during early and alpha surges in the United States. These findings highlight the need for improved management strategies and further research to better understand the impact of the virus on vulnerable populations during the COVID-19 pandemic.

Venous thromboembolism prophylaxis for hospitalized adult patients: a survey of US health care providers on attitudes and practices

Res Pract Thromb Haemost. 2023 Aug 7;7(6):102168. doi: 10.1016/j.rpth.2023.102168. eCollection 2023 Aug.

ABSTRACT

BACKGROUND: Venous thromboembolism (VTE) is a leading cause of preventable mortality among hospitalized patients, but appropriate risk assessment and thromboprophylaxis remain underutilized or misapplied.

OBJECTIVES: We conducted an electronic survey of US health care providers to explore attitudes, practices, and barriers related to thromboprophylaxis in adult hospitalized patients and at discharge.

RESULTS: A total of 607 US respondents completed the survey: 63.1% reported working in an academic hospital, 70.7% identified as physicians, and hospital medicine was the most frequent specialty (52.1%). The majority of respondents agreed that VTE prophylaxis is important (98.8%; 95% CI: 97.6%-99.5%) and that current measures are safe (92.6%; 95% CI: 90.2%-94.5%) and effective (93.8%; 95% CI: 91.6%-95.6%), but only half (52.0%; 95% CI: 47.9%-56.0%) believed that hospitalized patients at their institution are on appropriate VTE prophylaxis almost all the time. One-third (35.4%) reported using a risk assessment model (RAM) to determine VTE prophylaxis need; 44.9% reported unfamiliarity with RAMs. The most common recommendation for improving rates of appropriate thromboprophylaxis was to leverage technology. A majority of respondents (84.5%) do not reassess a patient's need for VTE prophylaxis at discharge, and a minority educates patients about the risk (16.2%) or symptoms (18.9%) of VTE at discharge.

CONCLUSION: Despite guideline recommendations to use RAMs, the majority of providers in our survey do not use them. A majority of respondents believed that technology could help improve VTE prophylaxis rates. A majority of respondents do not reassess the risk of VTE at discharge or educate patients about this risk of VTE at discharge.

Clinical Utility and Prognostic Value of Coronary Computed Tomography Angiography in Patients With Cancer

Am J Cardiol. 2023 Oct 3;207:448-454. doi: 10.1016/j.amjcard.2023.08.121. Online ahead of print.

ABSTRACT

There is growing interest in the role of coronary computed tomography angiography (CTA) in cardio-oncology. However, there is a paucity of real-world experience and outcome data for patients with cancer. This study sought to determine the clinical utility and prognostic value of coronary CTA in patients with cancer. In this prospective, single-center study, we recruited patients with cancer who underwent coronary CTA. Coronary artery disease (CAD) extent was classified as normal, nonobstructive (1% to 49% stenosis), and potentially obstructive (≥50% stenosis). Patients were followed up for a median of 9 months (interquartile range 3 to 30 months) for cancer-related deaths and major adverse cardiovascular events (MACEs) defined as nonfatal myocardial infarction, urgent unplanned revascularization, or cardiovascular death. The mean age of patients (n = 113) was 61 ± 12 years, and 68 were female (60%). The most common underlying cancers were breast (29%) and lymphoma (13%). A total of 25 patients had potentially obstructive CAD, most commonly of the left anterior descending artery. After coronary CTA, 88% statin-naive patients with potentially obstructive CAD were initiated on statin therapy. A total of 28/32 patients who were taking fluoropyrimidine chemotherapy (5-fluorouracil or capecitabine) continued therapy, of whom none had MACEs. Overall, there were no episodes of MACEs in this cohort and 11% had cancer-related deaths. Coronary CTA has an important role in the clinical decision-making in patients with cancer to detect CAD, initiate primary preventative therapy, and guide coronary revascularization. No MACEs occurred. Using this coronary CTA-guided approach, preventative therapy was initiated, and most patients continued prognostically important cancer therapy.

Approaches for reducing chemo/radiation-induced cardiotoxicity by nanoparticles

Environ Res. 2023 Sep 28:117264. doi: 10.1016/j.envres.2023.117264. Online ahead of print.

ABSTRACT

Nanoparticles are fascinating and encouraging carriers for cancer treatment due to their extraordinary properties and potential applications in targeted drug delivery, treatment, and diagnosis. Experimental studies including in vitro and in vivo examinations show that nanoparticles can cause a revolution in different aspects of cancer therapy. Normal tissue toxicity and early and late consequences are the major limitations of cancer therapy by radiotherapy and chemotherapy. However, the delivery of drugs into tumors or reducing the accumulation of drugs in normal tissues can permit a more satisfactory response of malignancies to therapy with more inferior side effects. Cardiac toxicity is one of the major problems for chemotherapy and radiotherapy. Therefore, several experimental studies have been performed to minimize the degenerative impacts of cancer treatment on the heart and also enhance the influences of radiotherapy and chemotherapy agents in cancers. This review article emphasizes the benefits of nanoparticle-based drug delivery techniques, including minimizing the exposure of the heart to anticancer drugs, enhancing the accumulation of drugs in cancers, and expanding the effectiveness of radiotherapy. The article also discusses the challenges and problems accompanied with nanoparticle-based drug delivery techniques such as toxicity, which need to be addressed through further research. Moreover, the article emphasizes the importance of developing safe and effective nanoparticle-based therapies that can be translated into clinical practice.

Tailored to a Woman's Heart: Gender Cardio-Oncology Across the Lifespan

Curr Cardiol Rep. 2023 Oct 11. doi: 10.1007/s11886-023-01967-7. Online ahead of print.

ABSTRACT

PURPOSE OF REVIEW: Females outnumber males among long-term cancer survivors, primarily as a result of the prevalence of breast cancer. Late cardiovascular effects of cancer develop over several decades, which for many women, may overlap with reproductive and lifecycle events. Thus, women require longitudinal cardio-oncology care that anticipates and responds to their evolving cardiovascular risk.

RECENT FINDINGS: Women may experience greater cardiotoxicity from cancer treatments compared to men and a range of treatment-associated hormonal changes that increase cardiometabolic risk. Biological changes at critical life stages, including menarche, pregnancy, and menopause, put female cancer patients and survivors at a unique risk of cardiovascular disease. Women also face distinct psychosocial and physical barriers to accessing cardiovascular care. We describe the need for a lifespan-based approach to cardio-oncology for women. Cardio-oncology care tailored to women should rigorously consider cancer treatment/outcomes and concurrent reproductive/hormonal changes, which collectively shape quality of life and cardiovascular outcomes.

Anthracycline‑induced delayed‑onset cardiac toxicity: A case report and literature review

Exp Ther Med. 2023 Sep 13;26(5):505. doi: 10.3892/etm.2023.12204. eCollection 2023 Nov.

ABSTRACT

Anthracyclic (ANT) drugs are widely used for patients with malignant tumors and can markedly prolong the disease-free survival rate of patients. As its clinical application becomes more common, information regarding serious cardiotoxicity as a result of ANT treatment is becoming understood. However, to the best of our knowledge, delayed-onset cardiotoxicity due to ANT use has not been studied sufficiently. The present report describes a 36-year-old male patient who presented to Guiqian International General Hospital (Guiyang, China) with a complaint of dyspnea in the last 10 days. Substantially elevated B-type natriuretic peptide levels and echocardiography showing enlargement of the entire heart, of the patient suggested that severe heart failure was the cause of his symptoms. However, the cause of this potential heart failure was not apparent until the patient was questioned about his cancer treatment history. Following consultation to evaluate the assessment of end-stage heart failure, currently only anti-heart failure treatment and symptomatic treatment can be provided. The present report describes this case and reviews the existing literature to provide a basis for the diagnosis and treatment of patients with delayed-onset heart failure following ANT treatment.

Utilizing coordination chemistry through formation of a CuII-quinalizarin complex to manipulate cell biology: An in vitro, in silico approach

J Inorg Biochem. 2023 Sep 21;249:112369. doi: 10.1016/j.jinorgbio.2023.112369. Online ahead of print.

ABSTRACT

Quinalizarin, an analogue of anthracycline anticancer agents, is an anticancer agent itself. A CuII complex was prepared and characterized by elemental analysis, UV-Vis & IR spectroscopy, mass spectrometry, EPR and DFT. The intention behind the preparation of the complex was to increase cellular uptake, compare its binding with DNA against that of quinalizarin, modulation of semiquinone formation, realization of human DNA topoisomerase I & human DNA topoisomerase II inhibition and observation of anticancer activity. While the first two attributes of complex formation lead to increased efficacy, decrease in semiquinone generation could results in a compromise with efficacy. Inhibition of human DNA topoisomerase makes up this envisaged compromise in free radical activity since the complex shows remarkable ability to disrupt activities of human DNA topoisomerase I and II. The complex unlike quinalizarin, does not catalyze flow of electrons from NADH to O2 to the extent known for quinalizarin. Hence, decrease in semiquinone or superoxide radical anion could make modified quinalizarin [as CuII complex] less efficient in free radical pathway. However, it would be less cardiotoxic and that would be advantageous to qualify it as a better anticancer agent. Although binding to calf thymus DNA was comparable to quinalizarin, it was weaker than anthracyclines. Low cost of quinalizarin could justify consideration as a substitute for anthracyclines but the study revealed IC50 of quinalizarin/CuII-quinalizarin was much higher than anthracyclines or their complexes. Even then, there is a possibility that CuII-quinalizarin could be an improved and less costly form of quinalizarin as anticancer agent.

Pyrotinib-based therapeutic approaches for HER2-positive breast cancer: the time is now

Breast Cancer Res. 2023 Oct 3;25(1):113. doi: 10.1186/s13058-023-01694-5.

ABSTRACT

Human epidermal growth factor receptor 2 (HER2)-positive breast cancer (BC) is a highly aggressive subtype associated with poor prognosis. The advent of HER2-targeted drugs, including monoclonal antibodies, tyrosine-kinase inhibitors (TKIs) and antibody-drug conjugates, has yielded improved prognosis for patients. Compared with widely used monoclonal antibodies, small-molecule TKIs have unique advantages including oral administration and favorable penetration of blood-brain barrier for brain metastatic BC, and reduced cardiotoxicity. Pyrotinib is an irreversible TKI of the pan-ErbB receptor, and has recently been shown to be clinically effective for the treatment of HER2-positive BC in metastatic and neoadjuvant settings. This review highlights the development on the application of pyrotinib-based therapeutic approaches in the clinical settings of HER2-positive BC.

Cancer survivorship at heart: a multidisciplinary cardio-oncology roadmap for healthcare professionals

Front Cardiovasc Med. 2023 Sep 15;10:1223660. doi: 10.3389/fcvm.2023.1223660. eCollection 2023.

ABSTRACT

In cancer, a patient is considered a survivor from the time of initial diagnosis until the end of life. With improvements in early diagnosis and treatment, the number of cancer survivors (CS) has grown considerably and includes: (1) Patients cured and free from cancer who may be at risk of late-onset cancer therapy-related cardiovascular toxicity (CTR-CVT); (2) Patients with long-term control of not-curable cancers in whom CTR-CVT may need to be addressed. This paper highlights the importance of the cancer care continuum, of a patient-centered approach and of a prevention-oriented policy. The ultimate goal is a personalized care of CS, achievable only through a multidisciplinary-guided survivorship care plan, one that replaces the fragmented management of current healthcare systems. Collaboration between oncologists and cardiologists is the pillar of a framework in which primary care providers and other specialists must be engaged and in which familial, social and environmental factors are also taken into account.

Echocardiographic Parameters Associated With Cardiorespiratory Fitness and Physical Activity in Childhood Acute Lymphoblastic Leukemia Survivors

J Phys Act Health. 2023 Oct 4:1-10. doi: 10.1123/jpah.2023-0100. Online ahead of print.

ABSTRACT

BACKGROUND: Children's exposure to chemotherapeutic agents causes several long-term adverse effects but physical activity has been evidenced to be an effective strategy to improve cardiac function. This cross-sectional study aimed to explore the association between physical activity levels, cardiorespiratory fitness, and cardiac parameters measured by echocardiography.

METHODS: Participants were 216n childhood acute lymphoblastic leukemia survivors who underwent a maximal cardiopulmonary exercise test and self-reported their daily minutes of moderate to vigorous physical activity. They underwent a complete transthoracic echocardiographic assessment. Systolic and diastolic function analysis and strain images analysis were performed. The associations were studied through the preventive fraction (examined with univariate crude and adjusted logistic regression models) of regular physical activity (≥150 min·wk-1) and adequate cardiorespiratory fitness levels (above the median ≥ 32.0 mL·kg-1·min-1) on cardiac parameters.

RESULTS: Crude analysis shows that regular physical activity was associated with a significant preventive fraction in mitral E/A ratio (56%; P = .013), while adjusted analyses highlighted a nonsignificant reduction of 74% to 37% in the prevalence of cardiac parameters associated with physical activity. Similar associations of adequate cardiorespiratory fitness on cardiac parameters were observed. Adjusted analyses revealed a nonsignificant reduction of 7% to 86% in the prevalence of cardiac parameters associated with cardiorespiratory fitness.

CONCLUSION: This study reports that regular physical activity and adequate cardiorespiratory fitness were associated with a higher preventive fraction. Thus, engaging in physical activity prevents childhood acute lymphoblastic leukemia survivors' cardiac dysfunctions. These findings are novel and clinically relevant in pediatric cardiooncology and provide additional evidence to strengthen the benefits of exercise as long-term care in childhood cancer survivors.

Management of Patients Treated with Direct Oral Anticoagulants in Clinical Practice and Challenging Scenarios

J Clin Med. 2023 Sep 13;12(18):5955. doi: 10.3390/jcm12185955.

ABSTRACT

It is well established that direct oral anticoagulants (DOACs) are the cornerstone of anticoagulant strategy in atrial fibrillation (AF) and venous thromboembolism (VTE) and should be preferred over vitamin K antagonists (VKAs) since they are superior or non-inferior to VKAs in reducing thromboembolic risk and are associated with a lower risk of intracranial hemorrhage (IH). In addition, many factors, such as fewer pharmacokinetic interactions and less need for monitoring, contribute to the favor of this therapeutic strategy. Although DOACs represent a more suitable option, several issues should be considered in clinical practice, including drug-drug interactions (DDIs), switching to other antithrombotic therapies, preprocedural and postprocedural periods, and the use in patients with chronic renal and liver failure and in those with cancer. Furthermore, adherence to DOACs appears to remain suboptimal. This narrative review aims to provide a practical guide for DOAC prescription and address challenging scenarios.
