  ABSTRACT In comparison to male patients with coronary artery disease, female patients suffer from more comorbidities, experience symptoms of coronary artery disease differently and report poorer health-related quality of life (HRQoL) after coronary revascularization. However, there is limited data on the impact of comorbidity burden on the recovery in HRQoL in female and male patients. We investigated the impact of comorbidity burden on the change in HRQoL following coronary revascularization in female patients versus male patients. 230 patients (60 female) with coronary artery disease were assessed before, and two weeks, three months and six months after coronary revascularization. Disease-specific HRQoL was measured with the Short-Form Seattle Angina Questionnaire. Physical and mental health was measured with the Short-Form Health Survey. Comorbidity burden was assessed by the total number of identified comorbidity conditions and by the Charlson comorbidity score. Linear mixed mode

 ABSTRACT PURPOSE OF REVIEW: Patients with cancer are at high risk for thrombotic events, mainly deep vein thrombosis and pulmonary embolism. Low-molecular-weight heparins (LMWHs) and direct oral anticoagulants (DOACs) are among the current treatment options for cancer-associated thrombosis (CAT). We assessed real world data (RWD) regarding treatment patterns of CAT from 1 September 2018 to 31 January 2020. RECENT FINDINGS: RWD showed that LMWHs were the most common initial anticoagulation treatment for CAT. Based on these data DOACs had a lower risk of recurrent venous thromboembolism compared with LMWHs and warfarin. However, the selection bias and the small number of patients in these studies might explain this difference and these limitations should be taken into consideration. Moreover, there was no statistical difference regarding adverse events during anticoagulant treatment between LMWHs and DOACs with the limitations of RWD. As far as the duration of the treatment is concerned

 ABSTRACT INTRODUCTION: Infantile hepatic hemangioendothelioma is a type of benign hepatic tumor that occurs in infancy. Many hepatic tumors are diagnosed when screening is done for multiple cutaneous hemangiomas. Hepatic tumors are small multifocal lesions and are mostly asymptomatic. There have been many case reports of asymptomatic infantile hepatic hemangioendothelioma, but few of these have pointed out that hepatic hemangiomas can sometimes be life-threatening due to fatal hepatomegaly complications such as pulmonary artery hypertension or even congestive heart failure. At present, there are no standard protocols for treating infantile hepatic hemangioendothelioma, though most clinicians agree that treatment is unnecessary for multiple small hepatic hemangiomas in asymptomatic patients. Little is known about treatment for cases with life-threatening complications induced by infantile hepatic hemangioendothelioma as there are so few reported cases. Here, we report a special case wi

 ABSTRACT PURPOSE: With the increasing interest in treatment decision-making based on risk prediction models, it is essential for clinicians to understand the steps in developing and interpreting such models. METHODS: A retrospective registry of 20 Dutch hospitals with data on patients treated for castration-resistant prostate cancer was used to guide clinicians through the steps of developing a prediction model. The model of choice was the Cox proportional hazard model. RESULTS: Using the exemplary dataset several essential steps in prediction modelling are discussed including: coding of predictors, missing values, interaction, model specification and performance. An advanced method for appropriate selection of main effects, e.g. Least Absolute Shrinkage and Selection Operator (LASSO) regression, is described. Furthermore, the assumptions of Cox proportional hazard model are discussed, and how to handle violations of the proportional hazard assumption using time-varying coefficients.

 ABSTRACT OBJECTIVE: To determine whether the pulmonary embolism (PE) categories of massive, submassive, PE with no right ventricle dysfunction (NRVD), and subsegmental only (SSO) adequately predict clinical outcome. METHODS: Patients treated for acute PE (March 1, 2013, through July 31, 2019) were followed forward prospectively to compare venous thromboembolism (VTE) recurrence, all-cause mortality, major bleeding, and clinically relevant nonmajor bleeding (CRNMB) across 4 PE categories. RESULTS: Of 2703 patients with VTE, 1188 (44%) had PE, of which 1021 (85.9%) completed at least 3 months of therapy or had clinical outcomes precluding further treatment (27 with massive, 217 submassive, 557 NRVD, and 220 SSO PE). One patient with massive, 8 with submassive, 23 with NRVD, and 5 with SSO PE had recurrent VTE (3.90, 5.33, 5.36, and 3.66 per 100 person-years, respectively; P=.84). There were 3 deaths in massive, 27 in submassive, 140 in NRVD, and 34 in SSO PE groups (11.59, 17.37, 31.74,

 ABSTRACT There is limited data on the effect of sacubitril-valsartan on the echocardiographic parameters in acute decompensated heart failure (ADHF). We prospectively enrolled 68 consecutive patients with ADHF who received sacubitril-valsartan (N = 34, S/V group) or angiotensin inhibition-based therapy (N = 34, ACEi/ARB group). Two-dimensional echocardiography with speckle tracking (2D-STE) was performed at baseline and after 3 months of treatment. Changes in 2D-STE parameters, including global longitudinal strain (GLS), were compared between the groups by t test and ANCOVA. Baseline characteristics were similar between the groups. Following 3 months of treatment, LVEF and GLS significantly improved in the S/V group (mean LVEF from 27 to 34.5% and GLS from - 6.6 to - 9.4%) but not in ACEi/ARB group. The improvement in LVEF and GLS was more prominent in patients with non-ischemic cardiomyopathy. In patients with ADHF 3-month treatment with sacubitril-valsartan, compared to guideline di

  ABSTRACT BACKGROUND: It is poorly understood how cardiovascular screening in asymptomatic childhood cancer survivors (CCS) is applied to and impacts clinical care. OBJECTIVES: To describe the current role of cardiovascular screening in the clinical care of asymptomatic CCS. METHODS: At 50 pediatric academic medical centers, a childhood cancer survivorship clinic director, pediatric cardiologist, and adult cardiologist with a focus on CCS were identified and invited to participate in a survey. Surveys were managed electronically. Categorical data were analyzed using nonparametric methods. RESULTS: Of the 95 (63%) respondents, 39% were survivorship practitioners, and 61% were cardiologists. Eighty-eight percent of survivorship practitioners reported that greater than half of CCS received cardiovascular screening. CCS followed by adult cardiology were more likely to be seen by a cardio-oncologist. Those followed by pediatric cardiology were more likely to be seen by a heart failure/tran

  ABSTRACT The senescence of vascular smooth muscle cells (VSMCs), characterized by the acquisition of senescence-associated secretory phenotype (SASP), is relevant for VSMCs osteoblastic differentiation and vascular calcification (VC). MicroRNA-34a (miR-34a) is a driver of such phenomena and could play a role in vascular inflammaging. Herein, we analyzed the relationship between miR-34a and the prototypical SASP component IL6 in in vitro and in vivo models. miR-34a and IL6 levels increased and positively correlated in aortas of 21 months-old male C57BL/6J mice and in human aortic smooth muscle cells (HASMCs) isolated from donors of different age and undergone senescence. Lentiviral overexpression of miR-34a in HASMCs enhanced IL6 secretion. HASMCs senescence and calcification accelerated after exposure to conditioned medium of miR-34a-overexpressing cells. Analysis of miR-34a-induced secretome revealed enhancement of several pro-inflammatory cytokines and chemokines, including IL6, pr

  ABSTRACT Venous thromboembolism (VTE) and major bleeding in primary central nervous system lymphoma (PCNSL) patients are not well described. We identified 992 PCNSL patients using the California Cancer Registry (2005-2014). The cumulative incidence of VTE and major bleeding was determined using California hospitalization data. The 12-month cumulative incidence of VTE was 13.6% (95% confidence interval (CI) 11.5-15.8%); chemotherapy and radiation therapy were associated with increased risk of VTE (hazard ratio (HR) 2.41, CI 1.31-4.46 and HR 1.56, CI 1.08-2.25, respectively). The 12-month cumulative incidence of major bleeding was 12.4% (CI 10.1-14.6%). Pulmonary embolism (PE) and proximal deep vein thrombosis were associated with increased risk of major bleeding, likely due to anticoagulation. PE (HR 1.61, CI 1.11-2.33, p=.011) and major bleeding (HR 2.36, CI 1.82-3.06, p<.0001) PMID:32573292 | DOI:10.1080/10428194.2020.1780584 ➖ Sent by @TheFeedReaderBot ➖ 09:10 PubMed articles on

  ABSTRACT Doxorubicin is a potent anticancer drug used to treat a variety of cancer types. However, its use is limited by doxorubicin-induced cardiotoxicity (DIC). A missense variant in the RARG gene (S427L; rs2229774) has been implicated in susceptibility to DIC in a genome wide association study. The goal of this study was to investigate the functional role of this RARG variant in DIC. We used induced pluripotent stem cell derived cardiomyocytes (iPSC-CMs) from patients treated with doxorubicin. iPSC-CMs from individuals who experienced DIC (cases) showed significantly greater sensitivity to doxorubicin compared to iPSC-CMs from doxorubicin-treated individuals who did not develop DIC (controls) in cell viability and optical mapping experiments. Using CRISPR/Cas9, we generated isogenic cell lines that differed only at the RARG locus. Genetic correction of RARG-S427L to wild type resulted in reduced doxorubicin-induced double stranded DNA breaks, reactive oxygen species production, an

 ABSTRACT A primary cardiac angiosarcoma is a rare type of soft-tissue sarcoma with a high mortality rate. This report describes a young woman who presented with chest pain and worsening shortness of breath over the course of a year. She was diagnosed with and treated for latent tuberculosis and autoimmune pericarditis over the last year, however, her condition kept worsening. Further workup revealed a large pericardial and right atrial mass associated with multiple lung nodules. The biopsy from the lung mass showed angiosarcoma, and she was diagnosed with primary metastatic angiosarcoma of the pericardium. She was treated with doxorubicin and Ifosfamide (AIM-75 regimen), which led to a partial response. However, soon after completion of six cycles, the tumour progressed rapidly, leading to cardio-respiratory failure. In this report, we will discuss the clinical challenges and treatment options (surgical and medical) that are available for treating patients with angiosarcoma of the hea

 ABSTRACT The patient was a 41-year-old woman, gravida 0. She had no notable medical history. Laparoscopic right salpingo-oophorectomy and left cystectomy were performed for bilateral ovarian endometriomas, which were both pathologically diagnosed as benign. Six months later, she presented with left lower abdominal pain and expressive aphasia. Examination revealed multiple cerebral infarctions and pulmonary embolism. The patient was diagnosed with Trousseau's syndrome secondary to ovarian cancer, and anticoagulant therapy was initiated. Despite treatment, she developed visual field loss due to occlusion of the left retinal artery; dizziness due to cerebellar infarction and myocardial infarction; and right hemiplegia due to new cerebral infarction. She received chemotherapy (two courses of paclitaxel and carboplatin), which did not improve her condition, and died two months after onset. An autopsy revealed that her left ovary was enlarged to a size of 12 cm and an endometrioid carci

  ABSTRACT BACKGROUND: PIPAC is a recent approach with promising results for patients with peritoneal metastasis (PM). We aimed to evaluate survival and postoperative outcome of patients with unresectable PM from gastric origin treated with chemotherapy and PIPAC. METHODS: A retrospective analysis of a prospective maintained PIPAC database was queried for all patients diagnosed with unresectable PM from gastric cancer who underwent PIPAC before 2018. PIPAC with Cisplatin 7.5 mg/m2 and doxorubicin 1.5 mg/m2 were given for 30 min at 6-week intervals. Outcome criteria were overall survival and adverse events according to (CTCAE) version4.0. RESULTS: One hundred Sixty-three PIPAC were done in 42 consecutive patients. Twenty-two (52%) of the patients were female. Signet-ring cells were observed in 33/42 patients (78.6%). At the first PIPAC, median age was 51.5 years (32-74). Median PCI was 17 (1-39). Twenty (47.6%) patients underwent more than 2 lines of pre-PIPAC chemotherapy. All patients

 ABSTRACT BACKGROUND: The use of perioperative thromboprophylaxis in urological surgery is common but not standardized. OBJECTIVE: To characterize international practice variation in thromboprophylaxis use in urological surgery. DESIGN, SETTING, AND PARTICIPANTS: We conducted a scenario-based survey addressing the use of mechanical and pharmacological thromboprophylaxis in urological cancer procedures (radical cystectomy [RC], radical prostatectomy [RP], and radical nephrectomy [RN]) among practicing urologists in Canada, Finland, and Japan. The survey presented patient profiles reflecting a spectrum of risk for venous thromboembolism; the respondents described their clinical practice. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The proportion of respondents who routinely used (1) mechanical, (2) pharmacological, and (3) extended pharmacological prophylaxis was stratified by procedure. A logistic regression identified characteristics associated with thromboprophylaxis use. RESULTS A

 ABSTRACT BACKGROUND: Sickle cell disease (SCD) is characterized by chronic hemolytic anemia, vaso-occlusive crises, chronic inflammation, and activation of coagulation. The clinical complications such as painful crisis, stroke, pulmonary hypertension, nephropathy and venous thromboembolism lead to cumulative organ damage and premature death. High molecular weight kininogen (HK) is a central cofactor for the kallikrein-kinin and intrinsic coagulation pathways, which contributes to both coagulation and inflammation. OBJECTIVE: We hypothesize that HK contributes to the hypercoagulable and pro-inflammatory state that causes end-organ damage and early mortality in sickle mice. METHODS: We evaluated the role of HK in the Townes mouse model of SCD. RESULTS/CONCLUSIONS: We found elevated plasma levels of cleaved HK in sickle patients compared to healthy controls, suggesting ongoing HK activation in SCD. We used bone marrow transplantation to generate wild type and sickle cell mice on a HK-def

 ABSTRACT Thymic carcinoma typically exhibits more clinically aggressive behavior and portends a worse prognosis as compared to thymoma. Venous thromboembolism is a significant cause of morbidity and mortality in oncologic patients. Traditionally, the standard-of-care management of cancer-associated venous thromboembolism has been therapeutic anticoagulation with low molecular weight heparins; however, with the advent of direct oral anticoagulants, there is an ongoing paradigm shift to transition to these novel agents in an attempt to attenuate cancer-associated venous thromboembolism events. We describe an exceedingly rare case of metastatic thymic carcinoma-associated right atrial thrombus with high-risk embolic features, which subsequently underwent near-complete dissolution with rivaroxaban after 3 months.

  ABSTRACT Cardiovascular diseases are possible complications of antineoplastic treatment and may lead to premature morbidity and mortality among cancer survivors. A symptom-based follow-up is ineffective, and there are growing evidences that early detection of myocardial damage in patients treated with antineoplastic drugs is the key point to prevent the occurrence of damage and improve the prognosis of these patients. Different techniques have been proposed to monitor cardiac function in oncologic patients such as cardiac imaging (echocardiography, nuclear imaging, and cardiac magnetic resonance) and biomarkers (troponin and natriuretic peptides). The European Association of Cardiovascular Imaging/American Society of Echocardiography consensus document encourages an integrated approach to early detect cardiotoxicity.

 ABSTRACT INTRODUCTION: Cerebral sinovenous thrombosis (CSVT) represents the second most common type of venous thromboembolism (VTE) in children. Current literature includes limited evidence on risk factors for CSVT, particularly in the pediatric population. We sought to determine risk factors for CSVT in pediatric patients through a single-institutional case-control study. In addition, we evaluated thrombophilias, treatments and outcomes in CSVT among cases. METHODS: A case-control study was performed at Johns Hopkins All Children's Hospital on patients admitted from March 31, 2006 through April 1, 2018. Cases were identified using diagnostic codes and confirmed based on electronic health record (EHR) and neuroimaging review. Controls were matched in a 2:1 fashion accounting for the month and year of admission. RESULTS: A total of 60 CSVT cases and 120 controls were identified. Median (range) age was 4.8 years (0-21.3 years) for cases and 5.6 years (0-20.0 years) for controls. Fac

 ABSTRACT BACKGROUND: Prognosis for patients with advanced hepatocellular carcinoma with a tumor thrombus in the inferior vena cava or right atrium is extremely poor due to cancer progression, pulmonary embolism, and congestion of the circulatory system caused by right heart failure. Surgical resection of the tumor thrombi may potentially yield better results than non-surgical treatments through prevention of sudden death. However, the benefits of surgical resection in patients with hepatocellular carcinoma and a tumor thrombus extending to the inferior vena cava, right atrium, and potentially in the phrenic vein are unclear. Here, we report three such cases. CASE PRESENTATION: Of the total 136 patients who underwent hepatectomies for hepatocellular carcinoma in our institution, three patients with prior hepatectomies and recurrent hepatocellular carcinoma had tumor thrombi in the inferior vena cava, right atrium, and phrenic vein. Surgical resections were performed, as there was a pos

 ABSTRACT Dealing with cancer is of importance due to enhanced incidence rate of this life-threatening disorder. Chemotherapy is an ideal candidate in overcoming and eradication of cancer. To date, various chemotherapeutic agents have been applied in cancer therapy and paclitaxel (PTX) is one of them. PTX is a key member of taxane family with potential anti-tumor activity against different cancers. Notably, PTX has demonstrated excellent proficiency in elimination of cancer in clinical trials. This chemotherapeutic agent is isolated from Taxus brevifolia, and is a tricyclic diterpenoid. However, resistance of cancer cells into PTX chemotherapy has endangered its efficacy. Besides, administration of PTX is associated with a number of side effects such as neurotoxicity, hepatotoxicity, cardiotoxicity and so on, demanding novel strategies in obviating PTX issues. Curcumin is a pharmacological compound with diverse therapeutic effects including anti-tumor, anti-oxidant, anti-inflammatory,

 ABSTRACT OBJECTIVE: Numerous guidelines have been published on the management of venous thromboembolism (VTE). However, therapeutic decision-making may prove challenging in routine clinical practice. With this in mind, multidisciplinary team (MDT) meetings have been set up in Rennes University Hospital, France. This study sought to describe the situations discussed during MDT meetings and to assess whether the meetings bring about changes in the management of these patients. MATERIALS AND METHODS: A retrospective single-center study conducted at the Rennes University Hospital included cases presented from the beginning of the MDT meetings (February 2015) up to May 2017. RESULTS: In total, 142 cases were presented in 15 MDT meetings, corresponding to a mean of 10±4 cases per meeting. Of these, 129 related to VTE patients: 33 provoked VTEs, 22 unprovoked VTEs, 49 cancer-related VTEs, and 25 unspecified VTEs. MDT meetings led to significant changes in the anticoagulation type (therapeuti

 ABSTRACT Sodium/glucose cotransporter-2 inhibitors (SGLT2i) are a new type of glucose-lowering drug that can reduce blood glucose by inhibiting its reabsorption in proximal tubules and by promoting urinary glucose excretion. SGLT2i are widely used in the clinical treatment of type 2 diabetes mellitus (T2DM). In recent studies, SGLT2i were found to not only reduce blood glucose but also protect the heart and kidney, which can significantly reduce cardiovascular events, delay the progression of renal failure, greatly improve the quality of life of patients, and reduce medical expenses for families and society. As adverse cardiac and renal events are the most common and serious complications of T2DM, it is very important to understand the cardio- and renoprotective mechanisms of SGLT2i. This article reviews the historical development, pharmacological mechanism, heart and kidney protection and safety of SGLT2i. The information presented provides a theoretical basis for the clinical preven

 ABSTRACT OBJECTIVES: Patients with gynecologic malignancies have high rates of post-operative venous thromboembolism. Currently, there is no consensus for peri-operative thromboprophylaxis specific to gynecologic oncology. We aimed to compare rates of symptomatic pulmonary embolus within 30 days post-operatively, and to identify risk factors for pulmonary embolus. METHODS: The Division of Gynecologic Oncology at Sunnybrook Health Sciences Centre implemented dual thromboprophylaxis for laparotomies in December 2017. We conducted a prospective study of laparotomies for gynecologic malignancies from December 2017 to October 2018, with comparison to historical cohort from January 2016 to November 2017 using the institutional National Surgical Quality Improvement Program database (NSQIP). Pre-intervention, patients received low molecular weight heparin during admission and extended 28-day prophylaxis was continued at the surgeon's discretion. Post-intervention, all patients received bo

  ABSTRACT There is currently increased interest in the use of the antimalarial drugs chloroquine and hydroxychloroquine for the treatment of other diseases, including cancer and viral infections such as coronavirus disease 2019 (COVID-19). However, the risk of cardiotoxic effects tends to limit their use. In this review, the effects of these drugs on the electrical and mechanical activities of the heart as well as on remodelling of cardiac tissue are presented and the underlying molecular and cellular mechanisms are discussed. The drugs can have proarrhythmic as well as antiarrhythmic actions resulting from their inhibition of ion channels, including voltage-dependent Na+ and Ca2+ channels, background and voltage-dependent K+ channels, and pacemaker channels. The drugs also exert a vagolytic effect due at least in part to a muscarinic receptor antagonist action. They also interfere with normal autophagy flux, an effect that could aggravate ischaemia/reperfusion injury or post-infarct

 ABSTRACT Backgrounds:The last 30 years have witnessed major improvements in understanding of all aspects of infective endocarditis (IE). The Iranian Registry of Infective Endocarditis (IRIE) was formed to address epidemiological aspects of IE vis-à-vis its main pathogens and underlying heart diseases over a 12-year period. Indeed, a multidisciplinary team (MDT) for IE was developed alongside.Methods: In a longitudinal observational study, data of adult patients with definite or possible IE based on modified Duke criteria were collected from 2007 to 2016 in our tertiary centre, Iran. From 2016 until 2019, we run a prospective observational study using formation of an IE MDT to provide better patient management and compared data before and after this.Results: Totally, 645 patients with mean age of 48 ± 17 years were enrolled. Data of 445 and 200 patients were compared before and after IRIE and MDT formation, respectively. We found significantly reduced type and number of applied antibio

 ABSTRACT Patients with multiple myeloma are at elevated risk of venous thromboembolism (VTE), the second leading cause of death in patients with cancer, but physician adherence to VTE prevention guidelines is low. Several organizations partnered in designing and implementing a 2-year quality improvement (QI) program in a tertiary care/academic cancer center, to increase awareness of VTE prophylaxis for patients with multiple myeloma and thus improve adherence to prophylaxis guidelines and protocols. The QI arm included 2 chart audits, conducted 2 years apart, of unmatched cohorts of 100 patients with multiple myeloma. An Education arm included 2 grand rounds presentations, 3 web-based case discussions, and a patient education module. Twenty providers took part in the continuous QI arm. More than 1100 learners participated in the online cases; the patient education curriculum reached 112 multiple myeloma patients. The initiative proved helpful in defining barriers to guideline adherenc

 ABSTRACT Venous thromboembolism (VTE) is associated with significant mortality and morbidity in patients with cancer. Therefore, tailoring anticoagulation is of utmost importance in order to decrease the risk of recurrent VTE while minimizing the risk of bleeding. Direct oral anticoagulants have been recently compared to low-molecular-weight heparin for the management of acute cancer-associated thrombosis. Although direct oral anticoagulants are a welcome addition, clinicians need to incorporate clinical characteristics, drug-drug interactions and patient preference in decision making.

 ABSTRACT Safety pharmacology is an essential part of drug development aiming to identify, evaluate and investigate undesirable pharmacodynamic properties of a drug primarily prior to clinical trials. In particular, cardiovascular adverse drug reactions (ADR) have halted many drug development programs. Safety pharmacology has successfully implemented a screening strategy to detect cardiovascular liabilities, but there is room for further refinement. In this setting, we present the INSPIRE project, a European Training Network in safety pharmacology for Early Stage Researchers (ESRs), funded by the European Commission's H2020-MSCA-ITN programme. INSPIRE has recruited 15 ESR fellows that will conduct an individual PhD-research project for a period of 36 months. INSPIRE aims to be complementary to ongoing research initiatives. With this as a goal, an inventory of collaborative research initiatives in safety pharmacology was created and the ESR projects have been designed to be compleme

 ABSTRACT Hemostatic abnormalities and thrombotic risk associated with coronavirus disease 2019 (COVID-19) are among the most discussed topics in the management of this disease. The aim of this position paper is to provide the opinion of Brazilian experts on the thromboprophylaxis and management of thrombotic events in patients with suspected COVID-19, in the sphere of healthcare in Brazil. To do so, the Brazilian Society of Thrombosis and Hemostasis (BSTH) and the Thrombosis and Hemostasis Committee of the Brazilian Association of Hematology, Hemotherapy and Cellular Therapy (ABHH) have constituted a panel of experts to carefully review and discuss the available evidence about this topic. The data discussed in this document was reviewed by May 9, 2020. Recommendations and suggestions reflect the opinion of the panel and should be reviewed periodically as new evidence emerges.

 ABSTRACT PURPOSE: Coronary artery calcification (CAC) progression is a strong predictor of cardiovascular disease (CVD) morbidity and mortality. However, the association between whole milk and CAC progression remains unknown. Recent studies highlighted beneficial effects of short chain fatty acids (SCFA) from whole milk on CVD. In this study, we attempted to investigate the relationship between whole milk consumption and CAC progression, and the potential effect of SCFA in it. METHODS: We analyzed a population-based cohort with 5273 participants from the Multi-Ethnic Study of Atherosclerosis (MESA) who completed a dietary questionnaire at baseline. CAC was measured at baseline and subsequent follow-up examinations by multi-detector computed tomography (MDCT) scans with Agatston scores. CAC progression was defined as increased CAC scores in the follow-up from the baseline exam. RESULTS: Participants consuming whole milk exhibited lower baseline CAC and CAC progression than those who ne

  ABSTRACT AIMS: To examine the efficacy and safety of direct oral anticoagulants (DOAC) versus low molecular weight heparin (LMWH) in patients with cancer-related venous thrombo-embolism (VTE). METHODS AND RESULTS: An electronic search of MEDLINE, SCOPUS and COCHRANE without language restrictions was performed through April 2020 for randomized controlled trials that compared the effects of DOACs versus LMWH on patients with cancer-related VTE. Summary estimates were reported using random effects model. The main efficacy outcome was VTE recurrence while the main safety outcome was major bleeding events. The final analysis included 4 randomized trials with a total of 2,907 patients. The weighted mean follow-up was 6.1 months. Compared with LMWH, DOACs were associated with lower risk of VTE recurrence (5.7% vs. 9.1%, risk ratio [RR] 0.62; 95% confidence interval [CI] 0.44 to 0.87; P = 0.01), driven by lower deep venous thrombosis (P = 0.02). There was no difference between DOACs and LMWH

  ABSTRACT Venous thromboembolism (VTE) represents a major health problem, especially in cancer patients, who experience a significantly higher incidence of both deep vein thrombosis and pulmonary embolism compared to the general population. Indeed, patients with cancer have a prothrombotic state resulting in both increased expression of procoagulants and suppression of fibrinolytic activity. In addition, VTE increases the morbidity and mortality of these patients. For all these reasons, the prevention and treatment of VTE in cancer setting represent major challenges in daily practice. In general, low-molecular-weight heparin monotherapy is the standard of care for the management of cancer-associated VTE, as Vitamin K antagonists are less effective in this setting. Direct oral anticoagulants offer a potentially promising treatment option for cancer patients with VTE, since recent studies demonstrated their efficacy and safety also in this peculiar setting.

  ABSTRACT Cardiovascular complications during chemotherapy and radiotherapy are becoming an increasing problem because many patients with cancer are treated with agents that exert significant vascular toxicity. Coronary heart disease in patients with cancer presents particular challenges, which directly impact the management of both the coronary disease and malignancy. Several chemotherapeutic agents have been shown to trigger ischemic heart disease, and as it has happened for myocardial cardiotoxicity, more attention should be dedicated to improving early recognition and prevention of cardiac vascular toxicity. Cardiac imaging could facilitate early detection of vascular toxicity, but a thorough risk stratification should always be performed to identify patients at higher risk of vascular impairment.

  ABSTRACT OBJECTIVES: To investigate the association of extremes in body weight EBW and outcomes in patients with acute venous thromboembolism (VTE), recurrent VTE, major bleeding, and clinically relevant non-major bleeding were compared between patients with body weight <60120 kg. METHODS: Consecutive patients enrolled in the Mayo Clinic VTE Registry (03/28/2013-8/31/2019) with acute VTE were followed prospectively. Patient status was assessed in person, by mailing a written questionnaire, or by a scripted phone interview. RESULTS: Amongst 2577 patients with the weight ranging from 27.0 kg to 263.2 kg, 2123 (82%) had a bodyweight between 60 - 120 kg, 223 (8.7%) bodyweight <60120 kg. Patients with bodyweight <60kg120kg and cancer on rivaroxaban had higher VTE recurrence compared to bodyweight 60-120kg group (p=0.01). CONCLUSIONS: Treatment of acute VTE is associated with a higher incidence of bleeding in patients with bodyweight <60kg.120kg on rivaroxaban. PMID:32557773 |

 ABSTRACT Even if cancer and cardiovascular diseases are considered two distinct diseases, an intricate interconnection between these conditions has been established. Increased risk of malignancy has been identified in patients with cardiovascular disease, as well as a greater propensity to the development of cardiovascular diseases has been observed in patients with cancer. The development of cardiotoxicity following exposure to certain anticancer drugs only partially explains this relationship. Shared risk factors and common pathogenic mechanisms suggest the existence of a common biology and a complex interplay between these two conditions. Due to improving longevity and therapeutic advances, the number of patients affected or potentially at risk of developing these two diseases is constantly increasing and currently, several drugs against cancer from anthracyclines to checkpoint inhibitors, can also cause a wide range of unexpected cardiovascular side effects. Management of these is

 ABSTRACT Positron emission tomography (PET) imaging is useful in cardiovascular disease across several areas, from assessment of myocardial perfusion and viability, to highlighting atherosclerotic plaque activity and measuring the extent of cardiac innervation in heart failure. Other important roles of PET have emerged in prosthetic valve endocarditis, implanted device infection, infiltrative cardiomyopathies, aortic stenosis and cardio-oncology. Advances in scanner technology, including hybrid PET/MRI and total body PET imaging, as well as the development of novel PET tracers and cardiac-specific postprocessing techniques using artificial intelligence will undoubtedly continue to progress the field.

 ABSTRACT External validation is a prerequisite in order for a prediction model to be introduced into clinical practice. Nonetheless, methodologically intact external validation studies are a scarce finding. Utilization of big datasets can help overcome several causes of methodological failure. However, transparent reporting is needed to standardize the methods, assess the risk of bias and synthesize multiple validation studies in order to infer model generalizability. We describe the methodological challenges faced when using multiple big datasets to perform the first retrospective external validation study of the Prospective Comparison of Methods for thromboembolic risk assessment with clinical Perceptions and AwareneSS in real life patients-Cancer Associated Thrombosis (COMPASS-CAT) Risk Assessment Model for predicting venous thromboembolism in patients with cancer. The challenges included choosing the starting point, defining time sensitive variables that serve both as risk factors

 ABSTRACT Oncocardiology is an emerging field in cardiovascular healthcare. Besides establishing surveillance and follow-up strategies for cancer patients, it will be essential to set up specialized oncocardiology services. However, there is a lack of clinical studies to give evidence-based recommendations regarding cardiological diagnostic and therapeutic approaches for cancer patients. An oncocardiology service is a patient-centered structure that aims to integrate research and interdisciplinary patient care to bridge this gap. We discuss the current challenges in developing an oncocardiology service and review the literature on this topic. We further provide an overview of the essential diagnostic tools and upcoming ethical issues to be considered in the management of oncology patients.

  ABSTRACT BACKGROUND: Venous thromboembolism (VTE) is a common postoperative complication. Previous studies have shown that the VTE incidence after major thoracic surgery is high. However, there have been no exclusive data after thymectomy thus far. To investigate the incidence of postoperative VTE, we conducted a single-center, prospective cohort study. METHODS: Patients who underwent thymectomy between December 2017 and January 2020 were enrolled. None of the patients received any prophylaxis perioperatively. Subjects were risk stratified into groups of low risk (0-4), moderate risk (5-8), and high risk (≥9). Occurrence of VTE events, including deep vein thrombosis (DVT) and pulmonary embolism (PE), were identified by imaging. RESULTS: There were 192 patients who underwent thymectomy enrolled into the study. The overall VTE incidence was 8.9%. All the patients were diagnosed with DVT, and none were diagnosed with PE. The VTE incidence was 4.6% in patients with benign thymic diseases

  ABSTRACT BACKGROUND: Doxorubicin and doxorubicin-trastuzumab combination chemotherapy have been associated with cardiotoxicity that eventually leads to heart failure and may limit dose-effective cancer treatment. Current diagnostic strategies rely on decreased ejection fraction (EF) to diagnose cardiotoxicity. PURPOSE: The aim of this study is to explore the potential of cardiac MR (CMR) imaging to identify imaging biomarkers in a mouse model of chemotherapy-induced cardiotoxicity. METHODS: A cumulative dose of 25 mg/kg doxorubicin was administered over three weeks using subcutaneous pellets (n = 9, Dox). Another group (n = 9) received same dose of Dox and a total of 10 mg/kg trastuzumab (DT). Mice were imaged at baseline, 5/6 weeks and 10 weeks post-treatment on a 7T MRI system. The protocol included short-axis cine MRI covering the left ventricle (LV) and mid-ventricular short-axis tissue phase mapping (TPM), pre- and post-contrast T1 mapping, T2 mapping and Displacement Encoding w

  ABSTRACT Absorbable inferior vena cava filters (IVCFs) offer a promising alternative to metallic retrievable filters in providing protection against pulmonary embolism (PE) for patients contraindicated for anticoagulant therapy. However, because absorbable filters are not radiopaque, monitoring of the filter using conventional X-ray imaging modalities (e.g. plain film radiographs, computed tomography [CT] and fluoroscopy) during deployment and follow-up is not possible and represents a potential obstacle to widespread clinical integration of the device. Here, we demonstrate that gold nanoparticles (AuNPs) infused into biodegradable filters made up of poly-p-dioxanone (PPDO) may improve device radiopacity without untoward effects on device efficacy and safety, as assessed in swine models for 12 weeks. The absorbable AuNP-infused filters demonstrated significantly improved visualization using CT without affecting tensile strength, in vitro degradation, in vivo resorption, or thrombus-c

 ABSTRACT As a result of better treatment options for malignant cancer, the cardiovascular side effects of such therapies have increasingly come into focus in recent years. The new cardiological subspecialty of oncocardiology is developing strategies to prevent and/or detect those effects early in order to treat them in a timely and adequate manner. The diagnosis of cardiotoxic effects is based mainly on imaging and specific biomarkers. Echocardiography has become the main imaging technique due to its wide availability. In addition to quantitative determination of left ventricular function using two-dimensional methods, three-dimensional methods offer better precision and less variability in the detection of cardiac dysfunction. Furthermore, the analysis of the global longitudinal strain (GLS) reveals even subtle changes in left ventricular function and thus detects very early damage before left ventricular ejection fraction drops. Various biomarkers have been tested recently for their

  ABSTRACT PURPOSE OF REVIEW: Patients with cancer have an elevated risk of cardiovascular disease. This review describes the cardiovascular risks of different cancer therapies and the evidence for cardioprotective strategies. RECENT FINDINGS: Recent studies have provided additional support for the safety and efficacy of dexrazoxane and liposomal anthracycline formulations in certain high-risk patients receiving anthracyclines and for neurohormonal antagonist therapy in patients with breast cancer receiving sequential anthracyclines and trastuzumab. Ongoing studies are exploring the benefit of: (1) statins for anthracycline cardioprotection; (2) strict blood pressure control during vascular endothelial growth factor inhibitor treatment and; (3) dexrazoxane on long-term cardiac outcomes in pediatric populations. To date, there are no evidence-based cardioprotective strategies specifically for radiation-related heart and vascular disease, immunotherapy myocarditis, fluoropyrimidine cardi

  ABSTRACT Venous thromboembolism (VTE) is a common complication of cancer that severely increases morbidity and mortality. Patients with intracranial tumors are more likely to develop VTE than patients with cancers at other sites. Conversely, limited tools exist to identify patients with high thrombotic risk. Upon activation, neutrophils release their content through different mechanisms triggering thrombosis. We explored the ability of microRNAs (miRNAs) and plasma markers of neutrophil activation measured before surgery to predict the risk of early post-surgical pulmonary embolism (PE) in glioma and meningioma patients. We recruited and prospectively followed 50 patients with glioma and 50 with meningioma, 34% of whom in each group developed an early objectively-diagnosed post-surgical PE. We measured miRNA expression and neutrophil markers (cell-free DNA, nucleosomes, calprotectin and myeloperoxidase) before surgery. In glioma patients, we adjusted and validated a predictive model

  ABSTRACT Cancer-associated venous thromboembolism (VTE) is a frequent, potentially life-threatening event that complicates cancer management. Anticoagulants are the cornerstone of therapy for the treatment and prevention of cancer-associated thrombosis (CAT); factor Xa-inhibiting direct oral anticoagulants (DOACs; apixaban, edoxaban, and rivaroxaban), which have long been recommended for the treatment of VTE in patients without cancer, have been investigated in this setting. The first randomized comparisons of DOACs against low-molecular-weight heparin for the treatment of CAT indicated that DOACs are efficacious in this setting, with findings reflected in recent updates to published guidance on CAT treatment. However, the higher risk of bleeding events (particularly in the gastrointestinal tract) with DOACs highlights the need for appropriate patient selection. Further insights will be gained from additional studies that are ongoing or awaiting publication. The efficacy and safety o

 ABSTRACT PURPOSE OF REVIEW: In this article, we review the different model systems based on human-induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) and how they have been applied to identify the cardiotoxic effects of anticancer therapies. RECENT FINDINGS: Developments on 2D and 3D culture systems enabled the use of hiPSC-CMs as screening platforms for cardiotoxic effects of anticancer therapies such as anthracyclines, monoclonal antibodies, and tyrosine kinase inhibitors. Combined with computational approaches and higher throughput screening technologies, they have also enabled mechanistic studies and the search for cardioprotective strategies. As the population ages and cancer treatments become more effective, the cardiotoxic effects of anticancer drugs become a bigger problem leading to an increased role of cardio-oncology. In the past decade, human-induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) have become an important platform for preclinical drug

 ABSTRACT BACKGROUND: Low-molecular-weight-heparins (LMWHs) have been established for the treatment of cancer-associated venous thromboembolism (VTE). Recently published randomized controlled trials (RCTs) have compared direct oral anticoagulants (DOACs) with LMWHs. The aim of this systematic review and meta-analysis was to evaluate efficacy and safety of DOACs versus LMWHs and update the evidence for treatment of VTE in cancer. METHODS: Biomedical databases were screened for RCTs evaluating DOACs for cancer-associated VTE. Primary efficacy and safety outcomes of this meta-analysis were recurrent VTE and major bleeding at 6 months. Secondary outcomes comprised clinically relevant nonmajor bleeding (CRNMB), major gastrointestinal (GI) and genitourinary bleeding, mortality, fatal bleeding/pulmonary embolism, and treatment discontinuation rate. We performed prespecified subgroup analyses. Pooled relative risk (RR) and 95% confidence intervals (CIs) were obtained by the Mantel-Haenszel met

 ABSTRACT Cancer therapy-related cardiotoxicity has been presenting a major problem in cancer survivors, who constitute a growing population caused by a significant improvement in cancer therapy during the past decades. Although some listing criteria have been defined for these patients, it is still a compelling decision to list patients with a complex cancer anamnesis. We describe herein a childhood cancer survivor after a cancer anamnesis with 2 different malignancies and an end-stage heart failure following chemoradiotherapy who was successfully treated with orthotopic heart transplant.

 ABSTRACT INTRODUCTION: We conducted a longitudinal study in patients with pancreatic and colorectal cancer. We determined the effect of chemotherapy on extracellular vesicle tissue factor (EVTF) activity and the association of plasma EVTF activity with venous thromboembolism (VTE) and survival. MATERIAL AND METHODS: We enrolled 13 patients with pancreatic and 22 patients with colorectal cancer. Plasma samples were collected during the 85-day study period. Patients were followed for 3 months after the study period. We recorded symptomatic VTE during the study period (3 months) or asymptomatic deep vein thrombosis detected by ultrasound at day 85. We measured EVTF activity before and after chemotherapy. RESULTS AND CONCLUSIONS: In the pancreatic cancer group, 2 patients had elevated levels of EVTF activity. One of these patients developed symptomatic VTE and died, and the second patient did not have a VTE but died. Chemotherapy decreased EVTF activity in 2 pancreatic patients with high

 ABSTRACT The anthracycline doxorubicin (Doxo) and its analogs daunorubicin (Daun), epirubicin (Epi), and idarubicin (Ida) have been cornerstones of anticancer therapy for nearly five decades. However, their clinical application is limited by severe side effects, especially dose-dependent irreversible cardiotoxicity. Other detrimental side effects of anthracyclines include therapy-related malignancies and infertility. It is unclear whether these side effects are coupled to the chemotherapeutic efficacy. Doxo, Daun, Epi, and Ida execute two cellular activities: DNA damage, causing double-strand breaks (DSBs) following poisoning of topoisomerase II (Topo II), and chromatin damage, mediated through histone eviction at selected sites in the genome. Here we report that anthracycline-induced cardiotoxicity requires the combination of both cellular activities. Topo II poisons with either one of the activities fail to induce cardiotoxicity in mice and human cardiac microtissues, as observed fo
