ABSTRACT

Immune checkpoint inhibitors (ICI) have changed the prognosis of many tumors. However, concerning associated cardiotoxicity has been reported. Little is known about the real-life incidence-specific surveillance protocols or the translational correlation between the underlying mechanisms and the clinical presentation of ICI-induced cardiotoxicity. The lack of data from prospective studies led us to review the current knowledge and to present the creation of the Spanish Immunotherapy Registry of Cardiovascular Toxicity (SIR-CVT), a prospective registry of patients receiving ICI that aims to examine the role of hsa-miR-Chr8:96, (a specific serum biomarker of myocarditis) in the early diagnosis of ICI-induced myocarditis. An exhaustive prospective cardiac imaging study will be performed before and during the first 12 months of treatment. The correlation between clinical, imaging, and immunologic parameters may improve our understanding of ICI-induced cardiotoxicity and enable simpler surveillance protocols. We assess ICI-induced cardiovascular toxicity and describe the rationale of the SIR-CVT.

Barbed palatal surgery: single stage or multilevel setting-a systematic review by the Young Otolaryngologists of the Italian Society of Otolaryngology

Eur Arch Otorhinolaryngol. 2023 May 25. doi: 10.1007/s00405-023-08018-5. Online ahead of print.

ABSTRACT

PURPOSE: This systematic review aims to compare the efficacy and safety of multilevel and single level surgery, including barbed pharyngoplasties, in the treatment of obstructive sleep apnea (OSA).

METHODS: The study followed PRISMA guidelines and searched PubMed/MEDLINE, Google Scholar, and Ovid databases for studies evaluating the effect of barbed pharyngoplasties on adults with OSA. Prospective and retrospective cohort studies were included with pre- and post-treatment comparisons of sleep tests and self-reported clinical outcomes. Exclusion criteria were non-English studies, case reports, reviews, conference abstracts, letters, and pediatric studies. Successful surgery was classified using Sher's criteria.

RESULTS: The study selected a total of 1014 patients from 26 studies, 24 of which were longitudinal studies with 10 retrospective trials and 14 prospective studies. The average age of the patients was 46.9 years, with an average Body Mass Index (BMI) of 25.6 kg/m2. Most of the patients were male (84.6%). The study included only palatal surgical techniques with barbed sutures, and patients who underwent cardio-respiratory monitoring and Drug Induced Sleep Endoscopy (DISE) before surgery. Mean Apnea Hypopnea Index (AHI) preoperative was 32.9/h, AHI postoperative was 11.9/h, and mean reduction of AHI was 62.3%. The most commonly adopted palatoplasty was Barbed Repositioning Pharyngoplasty (BRP) in 16 out of 26 studies, followed by its subsequent modifications in 3 studies.

CONCLUSIONS: Barbed pharyngoplasties appear to be effective both on objective measurement and subjective scores. DISE represents a fundamental tool to assess uni-level or multilevel obstruction. When retro-palatal collapse is present, barbed pharyngoplasty appears to be effective. Barbed pharyngoplasties maintain their good results both in single level or multilevel surgery. Randomized clinical controlled trials with multi-center cooperation and long-term study are necessary.

Tumour extracellular vesicles and particles induce liver metabolic dysfunction

Nature. 2023 May 24. doi: 10.1038/s41586-023-06114-4. Online ahead of print.

ABSTRACT

Cancer alters the function of multiple organs beyond those targeted by metastasis1,2. Here we show that inflammation, fatty liver and dysregulated metabolism are hallmarks of systemically affected livers in mouse models and in patients with extrahepatic metastasis. We identified tumour-derived extracellular vesicles and particles (EVPs) as crucial mediators of cancer-induced hepatic reprogramming, which could be reversed by reducing tumour EVP secretion via depletion of Rab27a. All EVP subpopulations, exosomes and principally exomeres, could dysregulate hepatic function. The fatty acid cargo of tumour EVPs-particularly palmitic acid-induced secretion of tumour necrosis factor (TNF) by Kupffer cells, generating a pro-inflammatory microenvironment, suppressing fatty acid metabolism and oxidative phosphorylation, and promoting fatty liver formation. Notably, Kupffer cell ablation or TNF blockade markedly decreased tumour-induced fatty liver generation. Tumour implantation or pre-treatment with tumour EVPs diminished cytochrome P450 gene expression and attenuated drug metabolism in a TNF-dependent manner. We also observed fatty liver and decreased cytochrome P450 expression at diagnosis in tumour-free livers of patients with pancreatic cancer who later developed extrahepatic metastasis, highlighting the clinical relevance of our findings. Notably, tumour EVP education enhanced side effects of chemotherapy, including bone marrow suppression and cardiotoxicity, suggesting that metabolic reprogramming of the liver by tumour-derived EVPs may limit chemotherapy tolerance in patients with cancer. Our results reveal how tumour-derived EVPs dysregulate hepatic function and their targetable potential, alongside TNF inhibition, for preventing fatty liver formation and enhancing the efficacy of chemotherapy.

Radiation Therapy-Induced Cardiac Toxicity

2023 May 29. In: StatPearls [Internet]. Treasure Island (FL): StatPearls Publishing; 2023 Jan–.

ABSTRACT

Radiation therapy is an important component in the treatment of cancer. It may play a role as an adjuvant, neoadjuvant, palliative, or definitive therapy, with or without concurrent chemotherapy. Radiation is most commonly delivered as a local/regional treatment by an external beam consisting of photons, electrons, protons, or heavy particles but may also be delivered via brachytherapy (where a sealed radiation source is placed adjacent to the target) or systemically via unsealed sources. The side effects of radiation therapy are a function of the tissues included in the radiation field. Treatment of diseases within the thoracic region, such as Hodgkin lymphoma, lung, and breast cancer, carries the risk of radiation-induced cardiovascular toxicity (RICT).

Side effects of therapeutic radiation to the heart and coronary vessels include pericarditis, coronary artery disease (CAD), arrhythmias, cardiomyopathy, valvular dysfunction, and heart failure. Pericarditis and pericardial effusions are potential short-term toxicities that may occur during or within the weeks following treatment. Long-term side effects may present in the months to years after radiation therapy, possibly as late as 20 years or more post-treatment. Late toxicities include CAD, valvular heart disease, and heart failure.

Major risk factors that increase the likelihood of RICT include higher radiation doses, adjuvant treatment with cardiotoxic chemotherapy, irradiation of the left side of the thorax, and the presence of pre-existing cardiovascular disease. Studies have correlated the mean dose of radiation received by various heart sub-structures to the incidence of major adverse cardiac events (MACE), such as hospitalization for heart failure, myocardial infarction, and even cardiac death. Given the importance of radiation therapy in treating cancer and the high prevalence of cardiovascular disease in Western populations, numerous preventive measures have been suggested and used in clinical practice, such as dose limitation, proton and particle therapy, conformal radiation therapy, and deep-inspiration breath-hold technique.

Cerebral infarction and in-hospital mortality for patients admitted to hospital with intracardiac thrombus: insights from the National Inpatient Sample

J Thromb Thrombolysis. 2023 Jun 5. doi: 10.1007/s11239-023-02824-8. Online ahead of print.

ABSTRACT

The factors associated with cerebral infarction and mortality in patients hospitalized with intracardiac thrombus are unknown. A retrospective cohort study was undertaken of nationally representative hospital admissions in the National Inpatient Sample with a diagnosis of intracardiac thrombus between 2016 to 2019. Multiple logistic regressions were used to define factors associated with cerebral infarction and in-hospital mortality. There were a total of 175,370 admissions for patients with intracardiac thrombus and 10.1% patients had cerebral infarction (n = 17,675). Intracardiac thrombus represented 4.4% of primary diagnosis for admissions while circulatory conditions (65.4%), infection (5.9%), gastrointestinal conditions (4.4%), respiratory conditions (4.4%) and cancer (2.2%) were the other prevalent primary diagnoses. All-cause mortality was higher for patients with cerebral infarction (8.5% vs 4.8%). The five factors most associated with cerebral infarction were nephrotic syndrome (OR 2.67 95%CI 1.05-6.78), other thrombophilia (OR 2.12 95%CI 1.52-2.95), primary thrombophilia (OR 1.99 95%CI 1.52-2.53), previous stroke (OR 1.61 95%CI 1.47-1.75) and hypertension (OR 1.41 95%CI 1.27-1.56). The strongest independent predictors of death were heparin induced thrombocytopenia (OR 2.45 95%CI 150-4.00), acute venous thromboembolism (OR 2.03 95%CI 1.78-2.33, p < 0.001) acute myocardial infarction (OR 1.95 95%CI 1.72-2.22), arterial thrombosis (OR 1.75 95%CI 1.39-2.20) and cancer (OR 1.57 95%CI 1.36-1.81). Patients with intracardiac thrombus are at risk of cerebral infarction and in-hospital mortality. Nephrotic syndrome, thrombophilia, previous stroke, hypertension, and heparin induced thrombocytopenia were associated with cerebral infarction, while acute venous thromboembolism, acute myocardial infarction, and cancer were predictors of mortality.

Pulmonary embolism in United States emergency departments, 2010-2018

Sci Rep. 2023 Jun 5;13(1):9070. doi: 10.1038/s41598-023-36123-2.

ABSTRACT

Little is known about pulmonary embolism (PE) in the United States emergency department (ED). This study aimed to describe the disease burden (visit rate and hospitalization) of PE in the ED and to investigate factors associated with its burden. Data were obtained from the National Hospital Ambulatory Medical Care Survey (NHAMCS) from 2010 to 2018. Adult ED visits with PE were identified using the International Classification of Diseases codes. Analyses used descriptive statistics and multivariable logistic regression accounting for the NHAMCS's complex survey design. Over the 9-year study period, there were an estimated 1,500,000 ED visits for PE, and the proportion of PE visits in the entire ED population increased from 0.1% in 2010-2012 to 0.2% in 2017-2018 (P for trend = 0.002). The mean age was 57 years, and 40% were men. Older age, obesity, history of cancer, and history of venous thromboembolism were independently associated with a higher proportion of PE, whereas the Midwest region was associated with a lower proportion of PE. The utilization of chest computed tomography (CT) scan appeared stable, which was performed in approximately 43% of the visits. About 66% of PE visits were hospitalized, and the trend remained stable. Male sex, arrival during the morning shift, and higher triage levels were independently associated with a higher hospitalization rate, whereas the fall and winter months were independently associated with a lower hospitalization rate. Approximately 8.8% of PE patients were discharged with direct-acting oral anticoagulants. The ED visits for PE continued to increase despite the stable trend in CT use, suggesting a combination of prevalent and incident PE cases in the ED. Hospitalization for PE remains common practice. Some patients are disproportionately affected by PE, and certain patient and hospital factors are associated with hospitalization decisions.

Comparison of long-term complications in cancer patients with incidental and acute symptomatic venous thromboembolism

Front Cardiovasc Med. 2023 May 19;10:1118385. doi: 10.3389/fcvm.2023.1118385. eCollection 2023.

ABSTRACT

BACKGROUND: Clinical practice guidelines recommend that patients with incidental venous thromboembolism (VTE) receive the same anticoagulant therapy as those with symptomatic VTE. We aimed to compare the rate of complications between cancer patients with incidental and symptomatic VTE through a long-term follow-up cohort.

METHODS: We performed a post hocanalysis of prospective studies of cancer patients with VTE between 2008 and 2019, with the primary outcome of rates of recurrent VTE and clinically relevant bleeding (CRB) in incidental and symptomatic VTE groups.

RESULTS: In total, 796 patients were included, of which 42.8% had incidental VTE. No significant differences were noted in the rate of recurrent VTE (0.4 per 100 patients/month vs. 0.5 per 100 patients/month; p= 0.313) and in the rate of CRB (0.6 per 100 patients/month vs. 0.5 per 100 patients/month; p= 0.128) between patients with incidental VTE and symptomatic VTE, respectively. At six-month follow-ups, the cumulative incidence of CRB was significantly higher in patients with incidental VTE than that in those with symptomatic VTE (7.9% vs. 4.4%, respectively; OR: 1.8; 95% CI: 1.01-3.2).

CONCLUSION: Cancer patients with incidental VTE had similar rates of CRB and VTE recurrence in long-term follow-up compared with patients with symptomatic VTE. At six-month follow-ups, patients with incidental VTE had a higher cumulative incidence of CRB than those with symptomatic VTE.

Role of 18F-FDG PET/CT in the diagnosis of benign vs. malignant tumor thrombus

Nucl Med Commun. 2023 Jun 5. doi: 10.1097/MNM.0000000000001708. Online ahead of print.

ABSTRACT

PURPOSE: Hypercoagulable state is a complication of various infections, and inflammatory processes and is a common scenario in cancer patients also. Timely diagnosis and treatment are essential to reduce further complications in such patients. The present study aimed to assess the role of FDG PET/CT in the diagnosis of benign vs. malignant tumor thrombus and to determine cut-off SUVmax to differentiate them.

PATIENTS AND METHODS: We retrospectively reviewed all FDG PET/CT scans of patients done in our department from January 2017 to March 2022. All scans were reviewed by two experienced nuclear medicine physicians. A total of 135 patients who had venous or arterial thrombus in FDG PET/CT scans were included. All the FDG PET/CT scans of 135 patients were analyzed for primary tumor site and/or site of thrombus. Additional clinical data were collected for patients with benign conditions in the form of ESR and CRP if available and doubtful cases were followed up by HPE reports and/or CEMRI. The SUV max of the primary tumor(in cancer patients), thrombus, and background (aorta) were calculated.

RESULTS: A total of 135 patients (108 cancer patients and 27 with benign thrombus) were included with an age range of 3 to 86 years (median 50 years). There were 91 males and 44 females. Of 108 cancer patients, the most common cancers were hepatocellular cancer - 38 (35.18%), renal cell cancer - 28(25.92%), and carcinoma of the thyroid - 6 (5.55%). Of 108 cancer patients, 36 (33.33%) had tumor thrombosis in inferior vena cava, 31 (28.70%) in the portal vein, and 41 (37.96%) in other vessels (renal vein, jugular vein, etc.). Of 27 patients with benign conditions,13 had venous thrombi, 11 had arterial thrombus and three had atrial thrombus and the most common thrombus sites were thoraco-abdominal aorta in seven (25.92%) and right atrium in three (11.11%) patients. In the subgroup of 108 oncological patients, the mean SUV max of the primary tumors was 17.67 (range 2.1-91.0; median 10.82), thrombi were 17.61 (range 2.14-90.11; median 14.56) and background was 5.29 (range 0.29-25.00; median 3.12). Of 27 patients with benign conditions, the mean SUV max of the thrombi was 11.09 (range 1.98-31; median 8.10) and the background was 9.80 (range 1.46-24.50; median 10.20) The ESR was raised in 13 of 26 patients (mean 35.84, range 10.98-62.00, median 35.00) and CRP was raised 22 of 26 patients (mean11.46, range 3.45-24.50, median 20.40). Upon plotting the receiver operating curve, a cutoff SUV max of 12.7 with a sensitivity of 62.96% and specificity of 77.77% was produced to demarcate tumor thrombus from benign thrombus.

CONCLUSION: FDG PET/CT plays a significant role in the detection of thrombo-embolic disease and can differentiate benign thrombus from tumor thrombus.

Risk for recurrence of symptomatic upper-extremity deep vein thrombosis in patients without cancer: Analysis of three RIETE cohorts

Vasc Med. 2023 Jun 5:1358863X231175185. doi: 10.1177/1358863X231175185. Online ahead of print.

ABSTRACT

BACKGROUND: The natural history of patients with a pacemaker-related upper-extremity deep vein thrombosis (UEDVT) has not been consistently studied.

METHODS: We used the RIETE registry data to compare the outcomes during anticoagulation and after its discontinuation in noncancer patients with symptomatic UEDVT associated with a pacemaker, other catheters, or no catheter. The major outcome was the composite of symptomatic pulmonary embolism or recurrent DVT.

RESULTS: As of February 2022, 2578 patients with UEDVT were included: 156 had a pacemaker-related UEDVT, 557 had other catheters, and 1865 had no catheter. During anticoagulation, 61 patients (2.3%) developed recurrent VTE, 38 had major bleeding (1.4%), and 90 died (3.4%). After its discontinuation, 52 patients (4.4%) had recurrent acute venous thromboembolism (VTE) and six had major bleeding (0.5%). On multivariable analysis, there were no differences among subgroups in the rates of VTE recurrences or major bleeding during anticoagulation. After its discontinuation, patients with a pacemaker-related UEDVT had a higher risk for VTE recurrences than those with no catheter (adjusted OR: 4.59; 95% CI: 1.98-10.6).

CONCLUSIONS: Patients with pacemaker-related UEDVT are at increased risk for VTE recurrences after discontinuing anticoagulation. If our findings are validated in adequately designed trials, this may justify changes in the current recommendations on the duration of anticoagulation.

D-dimer testing: A narrative review

Adv Clin Chem. 2023;114:151-223. doi: 10.1016/bs.acc.2023.02.006. Epub 2023 Mar 29.

ABSTRACT

D-dimer containing species are soluble fibrin degradation products derived from plasmin-mediated degradation of cross-linked fibrin, i.e., 'D-dimer'. D-dimer can hence be considered a biomarker of in vivo activation of both coagulation and fibrinolysis, the leading clinical application in daily practice of which is ruling out venous thromboembolism (VTE). D-dimer has been further evaluated for assessing the risk of VTE recurrence and helping define optimal duration of anticoagulation treatment in VTE, for diagnosing disseminated intravascular coagulation (DIC), and for screening those at enhanced risk of VTE. D-dimer assays should however be performed as intended by regulatory agencies, as their use outside these indications might make them a laboratory-developed test (LDT). This narrative review is aimed at: (1) reviewing the definition of D-dimer, (2) discussing preanalytical variables affecting D-dimer measurement, (3) reviewing and comparing the assays performance and some postanalytical variables (e.g., different units and age-adjusted cutoffs), and (4) discussing the interest of D-dimer measurement across different clinical settings, including pregnancy, cancer, and coronavirus disease 2019 (COVID-19).

Thrombotic Complications in Children with COVID-19 and MIS-C

J Thromb Haemost. 2023 May 31:S1538-7836(23)00434-8. doi: 10.1016/j.jtha.2023.05.020. Online ahead of print.

ABSTRACT

Coronavirus disease 2019 (COVID-19) associated coagulopathy is multifactorial and involves inflammation driven hypercoagulability, endothelial dysfunction, platelet activation and impaired fibrinolysis. Hospitalized adults with COVID-19 are at an increased risk of both venous thrombo-embolism (VTE) and ischemic stroke, resulting in adverse outcomes including mortality. While children with COVID-19 follow a less severe course, both arterial and venous thrombosis have been reported in hospitalized children with COVID-19. Additionally, some children develop a post-infectious, hyper-inflammatory illness termed Multisystem Inflammatory Syndrome of Childhood (MIS-C), which is also associated with hypercoagulability and thrombosis. Several randomized trials have evaluated the safety and efficacy of antithrombotic therapy in adults with COVID-19, though similar pediatric data are lacking. In this narrative review we discuss the postulated pathophysiology of COVID-19 coagulopathy, and summarize principal findings of the recently completed adult trials of antithrombotic therapy. We provide an up-to-date summary of pediatric studies investigating the rate of VTE and ischemic stroke in COVID-19 and MIS-C, in addition to reviewing the findings of the single, non-randomized pediatric trial investigating the safety of prophylactic anticoagulation. Lastly, we outline the adult and pediatric consensus guidelines on the use of antithrombotic therapy in this cohort. A detailed discussion of the practical implementation and current limitations of published data will hopefully address knowledge deficits surrounding the use of antithrombotic therapy in children with COVID-19, and generate hypotheses for future research.

Direct Oral Anticoagulants vs Low-Molecular-Weight Heparin and Recurrent VTE in Patients With Cancer: A Randomized Clinical Trial

JAMA. 2023 Jun 2. doi: 10.1001/jama.2023.7843. Online ahead of print.

ABSTRACT

IMPORTANCE: In patients with cancer who have venous thromboembolism (VTE) events, long-term anticoagulation with low-molecular-weight heparin (LMWH) is recommended to prevent recurrent VTE. The effectiveness of a direct oral anticoagulant (DOAC) compared with LMWH for preventing recurrent VTE in patients with cancer is uncertain.

OBJECTIVE: To evaluate DOACs, compared with LMWH, for preventing recurrent VTE and for rates of bleeding in patients with cancer following an initial VTE event.

DESIGN, SETTING, AND PARTICIPANTS: Unblinded, comparative effectiveness, noninferiority randomized clinical trial conducted at 67 oncology practices in the US that enrolled 671 patients with cancer (any invasive solid tumor, lymphoma, multiple myeloma, or chronic lymphocytic leukemia) who had a new clinical or radiological diagnosis of VTE. Enrollment occurred from December 2016 to April 2020. Final follow-up was in November 2020.

INTERVENTION: Participants were randomized in a 1:1 ratio to either a DOAC (n = 335) or LMWH (n = 336) and were followed up for 6 months or until death. Physicians and patients selected any DOAC or any LMWH (or fondaparinux) and physicians selected drug doses.

MAIN OUTCOMES AND MEASURES: The primary outcome was the recurrent VTE rate at 6 months. Noninferiority of anticoagulation with a DOAC vs LMWH was defined by the upper limit of the 1-sided 95% CI for the difference of a DOAC relative to LMWH of less than 3% in the randomized cohort that received at least 1 dose of assigned treatment. The 6 prespecified secondary outcomes included major bleeding, which was assessed using a 2.5% noninferiority margin.

RESULTS: Between December 2016 and April 2020, 671 participants were randomized and 638 (95%) completed the trial (median age, 64 years; 353 women [55%]). Among those randomized to a DOAC, 330 received at least 1 dose. Among those randomized to LMWH, 308 received at least 1 dose. Rates of recurrent VTE were 6.1% in the DOAC group and 8.8% in the LMWH group (difference, -2.7%; 1-sided 95% CI, -100% to 0.7%) consistent with the prespecified noninferiority criterion. Of 6 prespecified secondary outcomes, none were statistically significant. Major bleeding occurred in 5.2% of participants in the DOAC group and 5.6% in the LMWH group (difference, -0.4%; 1-sided 95% CI, -100% to 2.5%) and did not meet the noninferiority criterion. Severe adverse events occurred in 33.8% of participants in the DOAC group and 35.1% in the LMWH group. The most common serious adverse events were anemia and death.

CONCLUSIONS AND RELEVANCE: Among adults with cancer and VTE, DOACs were noninferior to LMWH for preventing recurrent VTE over 6-month follow-up. These findings support use of a DOAC to prevent recurrent VTE in patients with cancer.

Late-stage diagnosis of carcinoid heart disease due to lack of access to health care

Cardiooncology. 2023 Jun 5;9(1):28. doi: 10.1186/s40959-023-00176-z.

ABSTRACT

Carcinoid syndrome (CS) is a unique constellation of symptoms caused by release of vasoactive substances from neuroendocrine tumors (Pandit et al., StatPearls, 2022). Neuroendocrine tumors are rare with an annual incidence of 2 in 100,000 people (Ram et al., 46:21-27, 2019). Up to 50% of patients with these tumors will develop carcinoid syndrome, which is characterized by symptoms caused by elevated levels of serotonin and most commonly include fatigue, flushing, wheezing, and non-specific gastrointestinal symptoms such as diarrhea and malabsorption (Pandit et al., StatPearls, 2022) (Fox et.al., 90:1224-1228, 2004). Over time, patients with carcinoid syndrome can develop carcinoid heart disease (CHD). CHD refers to the cardiac complications that occur when the vasoactive substances, such as serotonin, tachykinins, and prostaglandins, secreted from the carcinoid tumors. These complications most commonly include valvular abnormalities, but can also present as coronary artery damage, arrhythmias or direct myocardial injury (Ram et al., 46:21-27, 2019). While CHD is not typically an initial feature of carcinoid syndrome, it does eventually occur in up to 70% of patients with carcinoid tumors (Ram et al., 46:21-27, 2019) (Jin et.al., 146:65-73, 2021) (Macfie et.al., 224:665-669, 2022). CHD is associated with significant morbidity and mortality due to the risk of progressive heart failure (Bober et.al., 14:1179546820968101, 2020). In this case, we describe a 35-year-old Hispanic woman in South Texas with undiagnosed carcinoid syndrome for over 10 years that eventually progressed to severe CHD. In this patient's case, we emphasize how lack of access to healthcare resulted in delay of diagnosis, appropriate treatment, and worsened prognosis in this young patient.

Towards optimal use of antithrombotic therapy of people with cancer at the end of life: A research protocol for the development and implementation of the SERENITY shared decision support tool

Thromb Res. 2023 May 13;228:54-60. doi: 10.1016/j.thromres.2023.05.008. Online ahead of print.

ABSTRACT

BACKGROUND: Even though antithrombotic therapy has probably little or even negative effects on the well-being of people with cancer during their last year of life, deprescribing antithrombotic therapy at the end of life is rare in practice. It is often continued until death, possibly resulting in excess bleeding, an increased disease burden and higher healthcare costs.

METHODS: The SERENITY consortium comprises researchers and clinicians from eight European countries with specialties in different clinical fields, epidemiology and psychology. SERENITY will use a comprehensive approach combining a realist review, flash mob research, epidemiological studies, and qualitative interviews. The results of these studies will be used in a Delphi process to reach a consensus on the optimal design of the shared decision support tool. Next, the shared decision support tool will be tested in a randomised controlled trial. A targeted implementation and dissemination plan will be developed to enable the use of the SERENITY tool across Europe, as well as its incorporation in clinical guidelines and policies. The entire project is funded by Horizon Europe.

RESULTS: SERENITY will develop an information-driven shared decision support tool that will facilitate treatment decisions regarding the appropriate use of antithrombotic therapy in people with cancer at the end of life.

CONCLUSIONS: We aim to develop an intervention that guides the appropriate use of antithrombotic therapy, prevents bleeding complications, and saves healthcare costs. Hopefully, usage of the tool leads to enhanced empowerment and improved quality of life and treatment satisfaction of people with advanced cancer and their care givers.

A Fondazione Italiana Linfomi cohort study of R-COMP vs R-CHOP in older patients with diffuse large B-cell lymphoma

Blood Adv. 2023 Jun 5:bloodadvances.2023009839. doi: 10.1182/bloodadvances.2023009839. Online ahead of print.

ABSTRACT

R-CHOP is the most commonly used regimen worldwide for the upfront treatment of diffuse large B-cell lymphoma (DLBCL). However, it is associated with significant cardiotoxicity, especially in older patients. The R-COMP regimen, with non-pegylated liposomal doxorubicin, may reduce the risk of cardiac events, but its efficacy has never been demonstrated in prospective trials. In this report, we describe the characteristics and outcome of DLBCL patients≥65 years prospectively enrolled in the Elderly Project by the Fondazione Italiana Linfomi and treated with full doses of R-CHOP or R-COMP per local practice. Starting from a dataset of 1163 cases, 383 (55%) were treated with R-CHOP and 308 (45%) with R-COMP. Patients treated with R-COMP were older (median age 76 vs 71 years), less frequently fit at simplified geriatric assessment (61% vs 88%, p<0.001),1, 32% vs 8%, p<0.001).

Levels of NT‑proBNP in patients with cancer

Oncol Lett. 2023 May 16;26(1):280. doi: 10.3892/ol.2023.13866. eCollection 2023 Jul.

ABSTRACT

At present, it is well known that natriuretic peptides may be produced by cancer cells. Stimulation of N-terminal pro B-type natriuretic peptide (NT-proBNP) synthesis may be a reaction to activity of several proinflammatory cytokines. NT-proBNP is also a marker of myocardial damage during cardiotoxic chemotherapy by anthracyclines. The present study aimed to analyze the association between NT-proBNP and patient/disease characteristics in patients without cardiac symptoms. The present clinical study included 112 patients with cancer who were undergoing anticancer therapy between December 2017 and December 2021. From each patient, peripheral blood was obtained for detection of NT-proBNP before any therapy, after therapy and 1 year after the first sample. NT-proBNP was examined using an immunochemical method. The mean ± SEM value of NT-pro-BNP in the first, second and third sample was 561.0±75.1, 1,565.4±461.1 and 1,940.7±581.1 ng/l. A total of 15 (13.4%), 27 (24.1%) and 25 (30.1%) patients had elevated levels of NT-pro-BNP in the first, second and third sample above the normal value adjusted to age. It was observed that NT-proBNP was increased in older patients and in patients with progressive metastatic disease with poor prognosis. Patients with non-elevated NT-proBNP in the second and third sample had significantly improved OS compared with patients with elevated NT-proBNP [hazard ratio (HR), 0.47; 95% CI, 0.26-0.85; P=0.002 for the second sample; and HR, 0.29; 95% CI, 0.14-0.60; P=0.0000007, for the third sample]. The baseline NT-proBNP value was not prognostic for OS (HR, 0.98; 95% CI, 0.50-1.92; P=0.96). The present results suggest that the level of NT-proBNP was associated with the extent of oncologic disease. Higher levels were associated with progression of metastatic disease and shorter overall survival.

Radiation-induced circulating microRNAs linked to echocardiography parameters after radiotherapy

Front Oncol. 2023 May 18;13:1150979. doi: 10.3389/fonc.2023.1150979. eCollection 2023.

ABSTRACT

INTRODUCTION: Patients treated with radiotherapy to the chest region are at risk of cardiac sequelae, however, identification of those with greatest risk of complications remains difficult. Here, we sought to determine whether short-term changes in circulating miRNA expression are related to measures of cardiac dysfunction in follow-up.

MATERIALS AND METHODS: Two parallel patient cohorts were enrolled and followed up for 3 years after completion of RT to treat left-sided breast cancer. In the primary group (N=28) we used a a panel of 752 miRNAs to identify miRNAs associated with radiation and cardiac indices at follow up. In the second, independent cohort (N=56) we validated those candidate miRNAs with a targeted qPCR panel. In both cohorts. serum samples were collected before RT, 24h after the last dose and 1 month after RT; cardiac echocardiography was performed 2.5-3 year after RT.

RESULTS: Seven miRNAs in the primary group showed marked changes in serum miRNAs immediately after RT compared to baseline and associations with cardiopulmonary dose-volume histogram metrics. Among those miRNAs: miR-15b-5p, miR-22-3p, miR-424-5p and miR-451a were confirmed to show significant decrease of expression 24 hours post-RT in the validation cohort. Moreover, miR-29c, miR-451 and miR-424 were correlated with the end-diastolic diameter of the left ventricle, which was also confirmed in multivariable analysis adjusting for RT-associated factors.

CONCLUSION: We identified a subset of circulating miRNAs predictive for cardiac function impairment in patients treated for left-sided breast cancer, although longer clinical observation could determine if these can be used to predict major clinical endpoints.

Monocyte-to-lymphocyte ratio as predictor of cancer therapy-related cardiotoxicity in patients with breast cancer: a pilot cohort study

Breast Cancer Res Treat. 2023 Jun 5. doi: 10.1007/s10549-023-06979-z. Online ahead of print.

ABSTRACT

BACKGROUND: Elevated pre-treatment baseline inflammation has been associated with cancer therapy-related cardiac dysfunction (CTRCD) in patients with breast cancer. Monocyte-to-lymphocyte ratio (MLR), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio and systemic immune-inflammation index (NLR × platelets) have emerged in clinical context as markers of disease-related inflammation.

OBJECTIVES: To evaluate development of CTRCD according to pre-treatment blood inflammatory biomarkers in patients with breast cancer.

METHODS: Pilot cohort study including consecutive female patients ≥ 18 years with HER2-positive early breast cancer who consulted at the institution's breast oncology outpatient clinic between march/2019 and march/2022. CTRCD: absolute reduction in LVEF > 10% to below 53% (2D-echocardiogram). Survival analysis was performed using Kaplan-Meier curves, compared by the log-rank test, and discrimination ability was evaluated through AUC-ROC.

RESULTS: Forty-nine patients (53.3 ± 13.3 y) were included and followed-up for a median of 13.2 months. CTRCD was observed in 6 (12.2%) patients. Patients with high blood inflammatory biomarkers had lower CTRCD-free survival (P < 0.050 for all). MLR showed statistically significant AUC (0.802; P = 0.017). CTRCD was observed in 27.8% of patients with high MLR versus 3.2% with low MLR (P = 0.020); negative predictive value was 96.8% (95%CI 83.3-99.4%).

CONCLUSION: In patients with breast cancer, elevated pre-treatment inflammatory markers were associated with increased risk of cardiotoxicity. Among these markers, MLR had good discriminatory performance and high negative predictive value. The incorporation of MLR might improve risk evaluation and selection of patients for follow-up during cancer therapy.

Potential for cardiac toxicity with methylimidazolium ionic liquids

Ecotoxicol Environ Saf. 2023 Jan 1;249:114439. doi: 10.1016/j.ecoenv.2022.114439. Epub 2022 Dec 19.

ABSTRACT

Methylimidazolium ionic liquids (MILs) are solvent chemicals used in industry. Recent work suggests that MILs are beginning to contaminate the environment and lead to exposure in the general population. In this study, the potential for MILs to cause cardiac toxicity has been examined. The effects of 5 chloride MIL salts possessing increasing alkyl chain lengths (2 C, EMI; 4 C, BMI; 6 C; HMI, 8 C, M8OI; 10 C, DMI) on rat neonatal cardiomyocyte beat rate, beat amplitude and cell survival were initially examined. Increasing alkyl chain length resulted in increasing adverse effects, with effects seen at 10-5 M at all endpoints with M8OI and DMI, the lowest concentration tested. A limited sub-acute toxicity study in rats identified potential cardiotoxic effects with longer chain MILs (HMI, M8OI and DMI) based on clinical chemistry. A 5 month oral/drinking water study with these MILs confirmed cardiotoxicity based on histopathology and clinical chemistry endpoints. Since previous studies in mice did not identify the heart as a target organ, the likely cause of the species difference was investigated. qRT-PCR and Western blotting identified a marked higher expression of p-glycoprotein-3 (also known as ABCB4 or MDR2) and the breast cancer related protein transporter BCRP (also known as ABCG2) in mouse, compared to rat heart. Addition of the BCRP inhibitor Ko143 - but not the p-glycoproteins inhibitor cyclosporin A - increased mouse cardiomyocyte HL-1 cell sensitivity to longer chain MILs to a limited extent. MILs therefore have a potential for cardiotoxicity in rats. Mice may be less sensitive to cardiotoxicity from MILs due in part, to increased excretion via higher levels of cardiac BCRP expression and/or function. MILs alone, therefore may represent a hazard in man in the future, particularly if use levels increase. The impact that MILs exposure has on sensitivity to cardiotoxic drugs, heart disease and other chronic diseases is unknown.

An ERK5-NRF2 Axis Mediates Senescence-Associated Stemness and Atherosclerosis

Circ Res. 2023 Jun 2. doi: 10.1161/CIRCRESAHA.122.322017. Online ahead of print.

ABSTRACT

BACKGROUND: ERK5 (extracellular signal-regulated kinase 5) is a dual kinase transcription factor containing an N-terminal kinase domain and a C-terminal transcriptional activation domain. Many ERK5 kinase inhibitors have been developed and tested to treat cancer and inflammatory diseases. However, recent data have raised questions about the role of the catalytic activity of ERK5 in proliferation and inflammation. We aimed to investigate how ERK5 reprograms myeloid cells to the proinflammatory senescent phenotype, subsequently leading to atherosclerosis.

METHODS: A ERK5 S496A (dephosphorylation mimic) KI (knock in) mouse model was generated using CRISPR/Cas9 (clustered regularly interspaced short palindromic repeats/clustered regularly interspaced short palindromic repeat-associated 9), and atherosclerosis was characterized by hypercholesterolemia induction. The plaque phenotyping in homozygous ERK5 S496A KI and WT (wild type) mice was studied using imaging mass cytometry. Bone marrow-derived macrophages were isolated from hypercholesterolemic mice and characterized using RNA sequencing and functional in vitro approaches, including senescence, mitochondria reactive oxygen species, and inflammation assays, as well as by metabolic extracellular flux analysis.

RESULTS: We show that atherosclerosis was inhibited in ERK5 S496A KI mice. Furthermore, ERK5 S496 phosphorylation mediates both senescence-associated secretory phenotype and senescence-associated stemness by upregulating AHR (aryl hydrocarbon receptor) in plaque and bone marrow-derived macrophages isolated from hypercholesterolemic mice. We also discovered that ERK5 S496 phosphorylation could induce NRF2 (NFE2-related factor 2) SUMOylation at a novel K518 site to inhibit NRF2 transcriptional activity without altering ERK5 catalytic activity and mediates oxidized LDL (low-density lipoprotein)-induced senescence-associated secretory phenotype. Specific ERK5 kinase inhibitors (AX15836 and XMD8-92) also inhibited ERK5 S496 phosphorylation, suggesting the involvement of ERK5 S496 phosphorylation in the anti-inflammatory effects of these ERK5 kinase inhibitors.

CONCLUSIONS: We discovered a novel mechanism by which the macrophage ERK5-NRF2 axis develops a unique senescence-associated secretory phenotype/stemness phenotype by upregulating AHR to engender atherogenesis. The finding of senescence-associated stemness phenotype provides a molecular explanation to resolve the paradox of senescence in proliferative plaque by permitting myeloid cells to escape the senescence-induced cell cycle arrest during atherosclerosis formation.

Long COVID syndrome after SARS-CoV-2 survival in patients with pulmonary arterial hypertension and chronic thromboembolic pulmonary hypertension

Pulm Circ. 2023 May 31;13(2):e12244. doi: 10.1002/pul2.12244. eCollection 2023 Apr.

ABSTRACT

Pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) patients have a more severe COVID-19 course than the general population. Many patients report different persistent symptoms after SARS-CoV-2 infection. The aim of our study is to analyze the prevalence of long COVID-19 symptoms and assess if COVID-19 affects pulmonary hypertension (PH) prognosis. PAH/CTEPH patients who survived COVID-19 for at least 3 months before visiting the PH centers were included in the study. The patients were assessed for symptoms in acute phase of SARS-CoV-2 infection and persisting in follow-up visit, WHO functional class, 6-min walk distance, NT-proBNP concentration. The COMPERA 2.0 model was used to calculate 1-year risk of death due to PH at baseline and at follow-up. Sixty-nine patients-54 (77.3%) with PAH and 15 (21.7%) with CTEPH, 68% women, with a median age of 47.5 years (IQR 37-68)-were enrolled in the study. About 17.1% of patients were hospitalized due to COVID-19 but none in an ICU. At follow-up (median: 155 days after onset of SARS-CoV-2 symptoms), 62% of patients reported at least 1 COVID-19-related symptom and 20% at least 5 symptoms. The most frequently reported symptoms were: fatigue (30%), joint pain (23%), muscle pain (17%), nasal congestion (17%), anosmia (13%), insomnia (13%), and dyspnea (12%). Seventy-two percent of PH patients had a low or intermediate-low risk of 1-year death due to PH at baseline, and 68% after COVID-19 at follow-up. Over 60% of PAH/CTEPH patients who survived COVID-19 suffered from long COVID-19 syndrome, but the calculated 1-year risk of death due to PH did not change significantly after surviving mild or moderate COVID-19.

Cerebral infarction and in-hospital mortality for patients admitted to hospital with intracardiac thrombus: insights from the National Inpatient Sample

J Thromb Thrombolysis. 2023 Jun 5. doi: 10.1007/s11239-023-02824-8. Online ahead of print.

ABSTRACT

The factors associated with cerebral infarction and mortality in patients hospitalized with intracardiac thrombus are unknown. A retrospective cohort study was undertaken of nationally representative hospital admissions in the National Inpatient Sample with a diagnosis of intracardiac thrombus between 2016 to 2019. Multiple logistic regressions were used to define factors associated with cerebral infarction and in-hospital mortality. There were a total of 175,370 admissions for patients with intracardiac thrombus and 10.1% patients had cerebral infarction (n = 17,675). Intracardiac thrombus represented 4.4% of primary diagnosis for admissions while circulatory conditions (65.4%), infection (5.9%), gastrointestinal conditions (4.4%), respiratory conditions (4.4%) and cancer (2.2%) were the other prevalent primary diagnoses. All-cause mortality was higher for patients with cerebral infarction (8.5% vs 4.8%). The five factors most associated with cerebral infarction were nephrotic syndrome (OR 2.67 95%CI 1.05-6.78), other thrombophilia (OR 2.12 95%CI 1.52-2.95), primary thrombophilia (OR 1.99 95%CI 1.52-2.53), previous stroke (OR 1.61 95%CI 1.47-1.75) and hypertension (OR 1.41 95%CI 1.27-1.56). The strongest independent predictors of death were heparin induced thrombocytopenia (OR 2.45 95%CI 150-4.00), acute venous thromboembolism (OR 2.03 95%CI 1.78-2.33, p < 0.001) acute myocardial infarction (OR 1.95 95%CI 1.72-2.22), arterial thrombosis (OR 1.75 95%CI 1.39-2.20) and cancer (OR 1.57 95%CI 1.36-1.81). Patients with intracardiac thrombus are at risk of cerebral infarction and in-hospital mortality. Nephrotic syndrome, thrombophilia, previous stroke, hypertension, and heparin induced thrombocytopenia were associated with cerebral infarction, while acute venous thromboembolism, acute myocardial infarction, and cancer were predictors of mortality.

Pulmonary embolism in United States emergency departments, 2010-2018

Sci Rep. 2023 Jun 5;13(1):9070. doi: 10.1038/s41598-023-36123-2.

ABSTRACT

Little is known about pulmonary embolism (PE) in the United States emergency department (ED). This study aimed to describe the disease burden (visit rate and hospitalization) of PE in the ED and to investigate factors associated with its burden. Data were obtained from the National Hospital Ambulatory Medical Care Survey (NHAMCS) from 2010 to 2018. Adult ED visits with PE were identified using the International Classification of Diseases codes. Analyses used descriptive statistics and multivariable logistic regression accounting for the NHAMCS's complex survey design. Over the 9-year study period, there were an estimated 1,500,000 ED visits for PE, and the proportion of PE visits in the entire ED population increased from 0.1% in 2010-2012 to 0.2% in 2017-2018 (P for trend = 0.002). The mean age was 57 years, and 40% were men. Older age, obesity, history of cancer, and history of venous thromboembolism were independently associated with a higher proportion of PE, whereas the Midwest region was associated with a lower proportion of PE. The utilization of chest computed tomography (CT) scan appeared stable, which was performed in approximately 43% of the visits. About 66% of PE visits were hospitalized, and the trend remained stable. Male sex, arrival during the morning shift, and higher triage levels were independently associated with a higher hospitalization rate, whereas the fall and winter months were independently associated with a lower hospitalization rate. Approximately 8.8% of PE patients were discharged with direct-acting oral anticoagulants. The ED visits for PE continued to increase despite the stable trend in CT use, suggesting a combination of prevalent and incident PE cases in the ED. Hospitalization for PE remains common practice. Some patients are disproportionately affected by PE, and certain patient and hospital factors are associated with hospitalization decisions.

Comparison of long-term complications in cancer patients with incidental and acute symptomatic venous thromboembolism

Front Cardiovasc Med. 2023 May 19;10:1118385. doi: 10.3389/fcvm.2023.1118385. eCollection 2023.

ABSTRACT

BACKGROUND: Clinical practice guidelines recommend that patients with incidental venous thromboembolism (VTE) receive the same anticoagulant therapy as those with symptomatic VTE. We aimed to compare the rate of complications between cancer patients with incidental and symptomatic VTE through a long-term follow-up cohort.

METHODS: We performed a post hocanalysis of prospective studies of cancer patients with VTE between 2008 and 2019, with the primary outcome of rates of recurrent VTE and clinically relevant bleeding (CRB) in incidental and symptomatic VTE groups.

RESULTS: In total, 796 patients were included, of which 42.8% had incidental VTE. No significant differences were noted in the rate of recurrent VTE (0.4 per 100 patients/month vs. 0.5 per 100 patients/month; p= 0.313) and in the rate of CRB (0.6 per 100 patients/month vs. 0.5 per 100 patients/month; p= 0.128) between patients with incidental VTE and symptomatic VTE, respectively. At six-month follow-ups, the cumulative incidence of CRB was significantly higher in patients with incidental VTE than that in those with symptomatic VTE (7.9% vs. 4.4%, respectively; OR: 1.8; 95% CI: 1.01-3.2).

CONCLUSION: Cancer patients with incidental VTE had similar rates of CRB and VTE recurrence in long-term follow-up compared with patients with symptomatic VTE. At six-month follow-ups, patients with incidental VTE had a higher cumulative incidence of CRB than those with symptomatic VTE.

Role of 18F-FDG PET/CT in the diagnosis of benign vs. malignant tumor thrombus

Nucl Med Commun. 2023 Jun 5. doi: 10.1097/MNM.0000000000001708. Online ahead of print.

ABSTRACT

PURPOSE: Hypercoagulable state is a complication of various infections, and inflammatory processes and is a common scenario in cancer patients also. Timely diagnosis and treatment are essential to reduce further complications in such patients. The present study aimed to assess the role of FDG PET/CT in the diagnosis of benign vs. malignant tumor thrombus and to determine cut-off SUVmax to differentiate them.

PATIENTS AND METHODS: We retrospectively reviewed all FDG PET/CT scans of patients done in our department from January 2017 to March 2022. All scans were reviewed by two experienced nuclear medicine physicians. A total of 135 patients who had venous or arterial thrombus in FDG PET/CT scans were included. All the FDG PET/CT scans of 135 patients were analyzed for primary tumor site and/or site of thrombus. Additional clinical data were collected for patients with benign conditions in the form of ESR and CRP if available and doubtful cases were followed up by HPE reports and/or CEMRI. The SUV max of the primary tumor(in cancer patients), thrombus, and background (aorta) were calculated.

RESULTS: A total of 135 patients (108 cancer patients and 27 with benign thrombus) were included with an age range of 3 to 86 years (median 50 years). There were 91 males and 44 females. Of 108 cancer patients, the most common cancers were hepatocellular cancer - 38 (35.18%), renal cell cancer - 28(25.92%), and carcinoma of the thyroid - 6 (5.55%). Of 108 cancer patients, 36 (33.33%) had tumor thrombosis in inferior vena cava, 31 (28.70%) in the portal vein, and 41 (37.96%) in other vessels (renal vein, jugular vein, etc.). Of 27 patients with benign conditions,13 had venous thrombi, 11 had arterial thrombus and three had atrial thrombus and the most common thrombus sites were thoraco-abdominal aorta in seven (25.92%) and right atrium in three (11.11%) patients. In the subgroup of 108 oncological patients, the mean SUV max of the primary tumors was 17.67 (range 2.1-91.0; median 10.82), thrombi were 17.61 (range 2.14-90.11; median 14.56) and background was 5.29 (range 0.29-25.00; median 3.12). Of 27 patients with benign conditions, the mean SUV max of the thrombi was 11.09 (range 1.98-31; median 8.10) and the background was 9.80 (range 1.46-24.50; median 10.20) The ESR was raised in 13 of 26 patients (mean 35.84, range 10.98-62.00, median 35.00) and CRP was raised 22 of 26 patients (mean11.46, range 3.45-24.50, median 20.40). Upon plotting the receiver operating curve, a cutoff SUV max of 12.7 with a sensitivity of 62.96% and specificity of 77.77% was produced to demarcate tumor thrombus from benign thrombus.

CONCLUSION: FDG PET/CT plays a significant role in the detection of thrombo-embolic disease and can differentiate benign thrombus from tumor thrombus.

Risk for recurrence of symptomatic upper-extremity deep vein thrombosis in patients without cancer: Analysis of three RIETE cohorts

Vasc Med. 2023 Jun 5:1358863X231175185. doi: 10.1177/1358863X231175185. Online ahead of print.

ABSTRACT

BACKGROUND: The natural history of patients with a pacemaker-related upper-extremity deep vein thrombosis (UEDVT) has not been consistently studied.

METHODS: We used the RIETE registry data to compare the outcomes during anticoagulation and after its discontinuation in noncancer patients with symptomatic UEDVT associated with a pacemaker, other catheters, or no catheter. The major outcome was the composite of symptomatic pulmonary embolism or recurrent DVT.

RESULTS: As of February 2022, 2578 patients with UEDVT were included: 156 had a pacemaker-related UEDVT, 557 had other catheters, and 1865 had no catheter. During anticoagulation, 61 patients (2.3%) developed recurrent VTE, 38 had major bleeding (1.4%), and 90 died (3.4%). After its discontinuation, 52 patients (4.4%) had recurrent acute venous thromboembolism (VTE) and six had major bleeding (0.5%). On multivariable analysis, there were no differences among subgroups in the rates of VTE recurrences or major bleeding during anticoagulation. After its discontinuation, patients with a pacemaker-related UEDVT had a higher risk for VTE recurrences than those with no catheter (adjusted OR: 4.59; 95% CI: 1.98-10.6).

CONCLUSIONS: Patients with pacemaker-related UEDVT are at increased risk for VTE recurrences after discontinuing anticoagulation. If our findings are validated in adequately designed trials, this may justify changes in the current recommendations on the duration of anticoagulation.
