Abstract
Abstract
Background
Right ventricle (RV) dysfunction at echocardiography is a recognized predictor of death or clinical deterioration in patients with acute pulmonary embolism (PE). However, the best predictor of death among echo parameters of RV dysfunction is unknown.
Purpose
This meta-analysis is aimed at assessing the role of individual parameter of RV dysfunction at echocardiography to predict all-cause short-term death in patients with acute PE.
Methods
OVID was searched between 1993 and January 2020 for studies i) including patients with confirmed acute PE; ii) reporting on RV assessment at echocardiography at admission; iii) reporting on short-term all-cause or PE-related death. The primary study outcome is short-term (30 days or in-hospital) all-cause mortality.
Results
We report here on the role of tricuspid annular plane excursion (TAPSE) and right-to-left ventricle diameter ratio (RV/LV) at echocardiography as predictors of short-term death in patients with acute PE. TAPSE. Abnormal TAPSE at echocardiography was associated with increased risk for short-term death in all-comers with acute PE (eight studies; 3298 patients; RR 2.78 CI 95% 0.53–14.63; Figure 1) and in hemodynamically stable patients (six studies; 3013 patients; RR 2.76 CI 95% 1.44–5.30 I2 58%). The association is confirmed for different cut-off values of TAPSE (≥15mm or any cut-off value >15mm). RV/LV. In eight studies reporting on continuous measures, the difference between mean right and left ventricle diameter at echocardiography in patients who died vs those who survived ranged from 0.02 to 0.3 mm. Abnormal RV/LV ratio at echocardiography was not associated with increased risk for short-term death in all-comers with acute PE (six studies; 2292 patients; RR 1.48 CI 95% 0.43–5.08), nor in hemodynamically stable patients (four studies; 1014 patients; RR 1.20 CI 95% 0.72–1.99, I2=0%).
Conclusion
Abnormal TAPSE is associated with short-term death in patients with acute PE. In these patients, the prognostic role of RV/LV diameter ratio as stand-alone parameter of RV dysfunction at echocardiography remains unclear.

Abstract
BACKGROUND The long-term risk for major bleeding in patients receiving extended (beyond the initial 3 to 6 months) anticoagulant therapy for a first unprovoked venous thromboembolism (VTE) is uncertain. PURPOSE To determine the incidence of major bleeding during extended anticoagulation of up to 5 years among patients with a first unprovoked VTE, overall, and in clinically important subgroups. DATA SOURCES MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials from inception to 23 July 2021. STUDY SELECTION Randomized controlled trials (RCTs) and prospective cohort studies reporting major bleeding among patients with a first unprovoked VTE who were to receive oral anticoagulation for a minimum of 6 additional months after completing at least 3 months of initial anticoagulant treatment. DATA EXTRACTION Two reviewers independently abstracted data and assessed study quality. Unpublished data required for analyses were obtained from authors of included studies. DATA SYNTHESIS Among the 14 RCTs and 13 cohort studies included in the analysis, 9982 patients received a vitamin K antagonist (VKA) and 7220 received a direct oral anticoagulant (DOAC). The incidence of major bleeding per 100 person-years was 1.74 events (95% CI, 1.34 to 2.20 events) with VKAs and 1.12 events (CI, 0.72 to 1.62 events) with DOACs. The 5-year cumulative incidence of major bleeding with VKAs was 6.3% (CI, 3.6% to 10.0%). Among patients receiving either a VKA or a DOAC, the incidence of major bleeding was statistically significantly higher among those who were older than 65 years or had creatinine clearance less than 50 mL/min, a history of bleeding, concomitant use of antiplatelet therapy, or a hemoglobin level less than 100 g/L. The case-fatality rate of major bleeding was 8.3% (CI, 5.1% to 12.2%) with VKAs and 9.7% (CI, 3.2% to 19.2%) with DOACs. LIMITATION Data were insufficient to estimate incidence of major bleeding beyond 1 year of extended anticoagulation with DOACs. CONCLUSION In patients with a first unprovoked VTE, the long-term risks and consequences of anticoagulant-related major bleeding are considerable. This information will help inform patient prognosis and guide decision making about treatment duration for unprovoked VTE. PRIMARY FUNDING SOURCE Canadian Institutes of Health Research.

Abstract
Efficacy and safety of anticoagulant treatment for venous thromboembolism (VTE) may vary in patients with different cancer sites. We evaluated the rates of VTE recurrence and major bleeding and the relative efficacy and safety of 6-month treatment with oral apixaban or subcutaneous dalteparin in patients with different cancer sites randomized in the Caravaggio study. Primary cancer was located at gastrointestinal sites in 375 patients (32.5%), lung in 200 (17.3%), breast in 155 (13.4%), genitourinary sites in 139 (12%), gynecological sites in 119 (10.3%), and was hematological in 85 patients (7.4%). Rates of VTE recurrence were 10.9% in patients with gynecological, 8.8% with gastrointestinal, 6.5% with genitourinary, and 5.5% with lung cancer with lower rates in the other sites of cancer. Rates of major bleeding were 7.2% in patients with genitourinary and 4.8% with gastrointestinal cancer, with lower rates in patients with other sites of cancer. The observed absolute risk difference in VTE recurrence in favor of apixaban was 11.9% in patients with gynecological, 5.5% with lung, 3.7% with genitourinary cancer, and 0.6% with gastrointestinal cancer. None of the risk differences was statistically significant. The rates of major bleeding in patients treated with apixaban or dalteparin was similar across patients with different cancer sites. In conclusion, recurrences appear to be more common in patients with gastrointestinal and gynecological cancer and major bleedings in patients with genitourinary and gastrointestinal cancer. Oral apixaban is a valid oral alternative to subcutaneous dalteparin for the treatment of a large spectrum of patients with cancer-associated VTE.

Abstract
The incidence of venous and arterial thromboembolic events in advanced cancer patients treated with immune checkpoint inhibitors (ICIs) has been sporadically reported. We performed a systematic review and meta-analysis to assess the rate of vascular events in patients with melanoma and non-small cell lung cancer (NSCLC) treated with ICIs. A systematic search of MEDLINE and EMBASE was performed to identify randomized clinical trials and prospective studies. The main outcomes were venous thromboembolism (VTE), stroke or systemic embolism (SE) and myocardial infarction (MI). Secondary outcomes were fatal VTE, fatal stroke or SE and fatal MI. Pooled proportions with 95% confidence intervals (CI) were calculated using random-effects models. A total of 59 trials, 25 in 5,578 patients with melanoma and 34 in 6,543 patients with NSCLC were included. In patients with melanoma, rates of VTE, stroke or SE and MI were 1.5% (95% CI 0.8-2.8), 1.7% (95% CI 0.8-3.7) and 0.4% (95% CI 0.2-0.9), respectively. In patients with NSCLC, corresponding rates were 1.9% (95% CI 1.2-3.2), 1.2% (95% CI 0.6-2.5), and 1.1% (95% CI 0.5-2.1), respectively. Rates of fatal VTE and MI were similar in melanoma and NSCLC patients. Rates of fatal stroke or SE were 1.9% (95% CI 0.4-9.5) and 0.7% (95% CI 0.2-2.3) in melanoma and NSCLC patients, respectively. Rates of VTE (3.1% vs. 1.1%) and myocardial infarction (3.4% Vs. 0.5%) were numerically higher in NSCLC patients treated with combined-ICIs vs mono-ICIs. Our study shows a not negligible rate of vascular events in patients with melanoma or NSCLC treated with ICIs.

Abstract
The effect of renal impairment (RI) on risk of bleeding and recurrent thrombosis in cancer patients treated with direct oral anticoagulants for venous thromboembolism (VTE) is undefined. We run a prespecified analysis of the randomized Caravaggio study to evaluate the role of RI as risk factor for bleeding or recurrence in patients treated with dalteparin or apixaban for cancer-associated VTE. RI was graded as moderate (creatinine clearance between 30-59 ml/minute; 275 patients) and mild (between 60-89 ml/minute; 444 patients). In 1142 patients included in this analysis, the incidence of major bleeding was similar in patients with moderate vs. no or mild RI (HR 1.06, 95% CI 0.53-2.11), with no difference in the relative safety of apixaban and dalteparin. Recurrent VTE was not different in moderate vs. no or mild RI (HR 0 .67, 95% CI 0.38-1.20); in moderate RI, apixaban reduced recurrent VTE compared to dalteparin (HR 0.27, 95% CI 0.08-0.96; P for interaction 0.1085). At multivariate analysis, no association was found between variation of renal function over time and major bleeding or recurrent VTE. Advanced or metastatic cancer was the only independent predictor of major bleeding (HR 2.84, 95% CI 1.20-6.71), with no effect of treatment with apixaban or dalteparin. In our study in cancer patients treated with apixaban or dalteparin, moderate RI was not associated with major bleeding or recurrent VTE. In patients with moderate renal failure, the safety profile of apixaban was confirmed with the potential for improved efficacy in comparison to dalteparin.

Abstract
BACKGROUND Limited data are available on the role of direct oral anticoagulants (DOACs) for the treatment of upper extremities deep vein thrombosis (UEDVT). OBJECTIVES The aim of this study was to assess the effectiveness and safety of DOACs in the treatment of UEDVT. METHODS Patients with an objectively confirmed acute UEDVT treated with DOACs were merged from prospective cohorts to a collaborative database. Primary study outcomes were recurrent venous thromboembolism (VTE) and major bleeding occurring during DOAC treatment. RESULTS Overall, 188 patients were included in the study: mean age 52.4 ± 20.4 years, males 43.6%, patients with active cancer 29.2%. Twenty-nine percent of patients had 2 or more risk factors for VTE, 33.0% had catheter-related or pacemaker-related UEDVT. In 13.8% of patients, DOACs were started one month after UEDVT diagnosis or later. Active cancer was an independent predictor for delayed initiation of DOACs (OR 8.1, 95% CI 3.0-22.2). Mean duration of treatment with DOACs was 5.1 ± 2.8 months. During treatment with DOACs, recurrent VTE occurred in 0.9 per 100 patient-year, major bleeding in 1.7 and all-cause deaths in 6.0 per 100 patient-year. No fatal bleeding or fatal VTE recurrence were observed. During 232.1 patient-years of follow-up after DOAC withdrawal, recurrent VTE occurred in 3.0 per 100 patient-year. The 2019 ESC categories for risk of VTE recurrences were able to discriminate patient groups at different risk of events in the on and off-treatment periods. CONCLUSIONS Our data support the feasibility as well as the effectiveness and safety of DOACs for the treatment of acute UEDVT.

Abstract
AIMS Patients with acute pulmonary embolism (PE) at low risk for short-term death are candidates for home treatment or short-hospital stay. We aimed at determining whether the assessment of right ventricle dysfunction (RVD) or elevated troponin improves identification of low-risk patients over clinical models alone. METHODS AND RESULTS Individual patient data meta-analysis of studies assessing the relationship between RVD or elevated troponin and short-term mortality in patients with acute PE at low risk for death based on clinical models (Pulmonary Embolism Severity Index, simplified Pulmonary Embolism Severity Index or Hestia). The primary study outcome was short-term death defined as death occurring in hospital or within 30 days. Individual data of 5010 low-risk patients from 18 studies were pooled. Short-term mortality was 0.7% [95% confidence interval (CI) 0.4-1.3]. RVD at echocardiography, computed tomography or B-type natriuretic peptide (BNP)/N-terminal pro BNP (NT-proBNP) was associated with increased risk for short-term death (1.5 vs. 0.3%; OR 4.81, 95% CI 1.98-11.68), death within 3 months (1.6 vs. 0.4%; OR 4.03, 95% CI 2.01-8.08), and PE-related death (1.1 vs. 0.04%; OR 22.9, 95% CI 2.89-181). Elevated troponin was associated with short-term death (OR 2.78, 95% CI 1.06-7.26) and death within 3 months (OR 3.68, 95% CI 1.75-7.74). CONCLUSION RVD assessed by echocardiography, computed tomography, or elevated BNP/NT-proBNP levels and increased troponin are associated with short-term death in patients with acute PE at low risk based on clinical models. RVD assessment, mainly by BNP/NT-proBNP or echocardiography, should be considered to improve identification of low-risk patients that may be candidates for outpatient management or short hospital stay.

Abstract
INTRODUCTION Sex and the presence of specific provoking risk factors, along with age, influence the presentation and prognosis of venous thromboembolism (VTE). We investigated the presentation, course and quality of life in women and men with acute VTE classified according to their VTE provoking factors. METHODS PREFER in VTE is an international, non-interventional registry of patients with a first episode of acute symptomatic VTE. Baseline provoking factors were classified as follows: major transient, minor transient, active cancer, and none identifiable. The primary outcome was recurrent VTE. Quality of life and treatment satisfaction were secondary outcomes. RESULTS Of 3,455 patients with acute VTE, 1,623 (47%) were women. The mean age at the time of VTE was 61 (SD 18) in women, 60 (SD 15) in men. The distribution of provoking risk factors was similar between sexes, despite a tendency for higher frequency of minor and major transient risk factors in women, and cancer or unprovoked VTE in men. At 12-month follow-up, VTE recurrence was reported in 74 (6.5%) women and 80 (6.4%) men (absolute risk difference -0.1%, 95% CI -1.9%; +2.1%). In patients with unprovoked VTE, the VTE recurrence rate was 38/612 (6.2%) in women and 53/798 (6.6%) in men (absolute risk difference -0.4, 95% CI -3.0; +2.1%). Multivariable Cox regressions confirmed the absence of sex differences. Quality of life and treatment satisfaction scores one year after VTE were lower in women than in men irrespective of the provoking risk factors (p<0.001 for both scores). CONCLUSIONS Despite differences in the provoking risk factors for VTE, women and men had a similar rate VTE recurrence at one year. After acute VTE, women had lower quality of life and treatment satisfaction scores.

Abstract
BACKGROUND Severe acute respiratory syndrome coronavirus 2 infection is associated with hypercoagulability, which predisposes to venous thromboembolism (VTE). We analyzed platelet and neutrophil activation in patients with coronavirus disease 2019 (COVID-19) and their association with VTE. METHODS Hospitalized patients with COVID-19 and age- and sex-matched healthy controls were studied. Platelet and leukocyte activation, neutrophil extracellular traps (NETs), and matrix metalloproteinase 9, a neutrophil-released enzyme, were measured. Four patients were restudied after recovery. The activating effect of plasma from patients with COVID-19 on control platelets and leukocytes and the inhibiting activity of common antithrombotic agents on it were studied. RESULTS A total of 36 patients with COVID-19 and 31 healthy controls were studied; VTE developed in 8 of 36 patients with COVID-19 (22.2%). Platelets and neutrophils were activated in patients with COVID-19. NET, but not platelet activation, biomarkers correlated with disease severity and were associated with thrombosis. Plasmatic matrix metalloproteinase 9 was significantly increased in patients with COVID-19. Platelet and neutrophil activation markers, but less so NETs, normalized after recovery. In vitro, plasma from patients with COVID-19 triggered platelet and neutrophil activation and NET formation, the latter blocked by therapeutic-dose low-molecular-weight heparin, but not by aspirin or dypiridamole. CONCLUSIONS Platelet and neutrophil activation are key features of patients with COVID-19. NET biomarkers may help to predict clinical worsening and VTE and may guide low-molecular-weight heparin treatment.

Abstract
BACKGROUND Whether concomitant administration of anticancer agents influences the efficacy and safety of oral anticoagulants in patients treated for cancer-associated venous thromboembolism (VTE) is undefined. The pharmacological interaction between anticancer agents and direct oral anticoagulants is perceived as a concern. METHODS We evaluated the effects of concomitant administration of anticancer agents on recurrent VTE, major bleeding and death in patients with cancer-associated VTE randomised to receive apixaban or dalteparin in the Caravaggio study. RESULTS Anticancer agents were concomitantly given to 336 patients (58.3%) treated with apixaban and to 332 patients (57.3%) treated with dalteparin. In patients treated with apixaban, recurrent VTE occurred in 20 (6.0%) and 12 (5.0%) among patients treated or not treated with anticancer agents, respectively (hazard ratio [HR] = 1.14; 0.55-2.38); major bleeding occurred in 12 (3.6%) and 10 (4.2%) patients , respectively (HR = 0.79; 0.34-1.82), and death occurred in 74 (22.0%) and 61 (25.4%) patients , respectively (HR = 0.71; 0.51-1.00). In patients treated with dalteparin, recurrent VTE occurred in 24 (7.2%) and 22 (8.9%) among patients treated or not treated with anticancer agents, respectively (HR = 0.71; 0.40-1.28); major bleeding occurred in 16 (4.8%) and 7 (2.8%) patients, respectively (HR = 1.78; 0.66-4.79), and death occurred in 87 (26.2%) and 66 (26.7%) patients, respectively (HR = 0.85; 0.62-1.18). The comparative efficacy and safety of apixaban and dalteparin was not different in patients treated or not treated with anticancer agents. No effect on recurrent VTE, major bleeding or death was observed with inhibitors or inducers of P-glycoprotein and/or CYP3A4. CONCLUSION In our study, concomitant administration of anticancer agents had no effect on the risk of VTE recurrence or major bleeding in patients treated with apixaban or dalteparin for cancer-associated VTE.

Abstract
AIMS To investigate the efficacy and safety of early transition from hospital to ambulatory treatment in low-risk acute PE, using the oral factor Xa inhibitor rivaroxaban. METHODS AND RESULTS We conducted a prospective multicentre single-arm investigator initiated and academically sponsored management trial in patients with acute low-risk PE (EudraCT Identifier 2013-001657-28). Eligibility criteria included absence of (i) haemodynamic instability, (ii) right ventricular dysfunction or intracardiac thrombi, and (iii) serious comorbidities. Up to two nights of hospital stay were permitted. Rivaroxaban was given at the approved dose for PE for ≥3 months. The primary outcome was symptomatic recurrent venous thromboembolism (VTE) or PE-related death within 3 months of enrolment. An interim analysis was planned after the first 525 patients, with prespecified early termination of the study if the null hypothesis could be rejected at the level of α = 0.004 (<6 primary outcome events). From May 2014 through June 2018, consecutive patients were enrolled in seven countries. Of the 525 patients included in the interim analysis, three (0.6%; one-sided upper 99.6% confidence interval 2.1%) suffered symptomatic non-fatal VTE recurrence, a number sufficiently low to fulfil the condition for early termination of the trial. Major bleeding occurred in 6 (1.2%) of the 519 patients comprising the safety population. There were two cancer-related deaths (0.4%). CONCLUSION Early discharge and home treatment with rivaroxaban is effective and safe in carefully selected patients with acute low-risk PE. The results of the present trial support the selection of appropriate patients for ambulatory treatment of PE.

Abstract
Venous thromboembolism (VTE) is a common complication after intracranial hemorrhage (ICH); the incidence has been reported to vary between 18% to 50% for deep vein thrombosis and between 0.5% to 5% for pulmonary embolism (PE). According to current clinical practice guidelines, patients with acute VTE should receive anticoagulant treatment for at least 3 months in the absence of contraindications. Anticoagulant treatment reduces mortality, prevents early recurrences and improves long-term outcome in patients with acute VTE. However, recent ICH is an absolute contraindication for anticoagulant treatment due to the potential increased risk of hematoma expansion or recurrent ICH. Hematoma expansion occurs in approximately a third of patients within 24 h following the diagnosis of a spontaneous ICH. The risk for recurrent ICH depends on patients' features as well as on the feature of index ICH. Limited evidence is available on the risks of therapeutic anticoagulation started shortly after ICH. Expert consensus around the introduction of therapeutic anticoagulation suggests delaying therapeutic anticoagulation for at least 2 weeks after spontaneous ICH, until the risk re-bleeding becomes acceptable. Vena cava filters should be inserted to reduce the risk for (non) fatal PE until therapeutic anticoagulation can be started; antithrombotic prophylaxis should be started as soon as possible to avoid recurrent VTE after vena cava filter insertion. For patients presenting PE with hemodynamic compromise, percutaneous embolectomy should be considered. Most patients will be able to receive anticoagulant treatment within 4 weeks following spontaneous ICH; direct oral anticoagulants are probably the treatment of choice for those ICH patients tolerating anticoagulant treatment.

Abstract
The infection by the novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is associated with significant cardiovascular morbidity and mortality. Cardiac events require prompt diagnosis and management, also in the SARS-CoV-2 era. A 58-year-old male, heavy smoker and with known SARS-CoV-2 infection, abruptly developed severe hypotension and asthenia. At patients' home, emergency physicians found hemodynamic compromise with diffuse ST-elevation at electrocardiography. The patient was rapidly moved to the cardiac catheterization laboratory, and any contact with other health-care workers was avoided. Coronary angiography excluded coronary artery disease. At admission to the coronavirus disease-2019 unit, an increase in inflammatory markers and liver enzymes with normal troponin levels were observed. Bedside lung ultrasonography showed interstitial syndrome and bilateral pleural effusion, whereas echocardiography showed large and diffuse pericardial effusion with a swinging heart. The hemodynamic status improved after gentle fluid therapy such suggesting potential concomitant sepsis and pericardiocentesis was not performed. At this time, a computed tomography scan showed a widespread neoplasm in the right lung involving the subclavian artery and vein and the thoracic lymph nodes. The histology confirmed the diagnosis of a locally advanced pulmonary adenocarcinoma. One week after admission, the patient died for worsening respiratory failure. Not delayed primary PCI remains the standard of care for patients with suspected ST-elevation myocardial infarction (STEMI) in the SARS-CoV-2 era. A diagnostic deepening for potential STEMI-mimicker (known to be associated with SARS-CoV-2 infection and to patients' comorbidities) should be considered, and a multidisciplinary approach is needed in these patients.

Abstract
The frequent finding of thrombocytopenia in patients with severe SARS-CoV-2 infection (COVID-19) and previous evidence that several viruses enter platelets suggest that SARS-CoV-2 might be internalized by platelets of COVID-19. Aim of our study was to assess the presence of SARS-CoV-2 RNA in platelets from hospitalized patients with aconfirmed diagnosis of COVID-19. RNA was extracted from platelets, leukocytes and serum from 24 COVID-19 patients and 3 healthy controls, real-time PCR and ddPCR for viral genes were carried out. SARS-CoV-2 RNA was not detected in any of the samples analyzed nor in healthy controls, by either RT-PCR or ddPCR, while RNA samples from nasopharyngeal swabs of COVID-19 patients were correctly identified. Viral RNA was not detected independently of viral load, of positive nasopharyngeal swabs, or viremia, the last detected in only one patient (4.1%). SARS-CoV-2 entry in platelets is not acommon phenomenon in COVID-19 patients, differently from other viral infections.

Abstract
BACKGROUND Tachycardia is a reliable predictor of adverse outcomes in normotensive patients with acute pulmonary embolism (PE). However, different prognostic relevant heart rate thresholds have been proposed. The aim of the study was to investigate the prognostic performance of different thresholds used for defining tachycardia in normotensive PE patients. METHODS We performed a post-hoc analysis of normotensive patients with confirmed PE consecutively included in a single-centre and a multi-centre registry. An adverse outcome was defined as PE-related death, need for mechanical ventilation, cardiopulmonary resuscitation or administration of catecholamines. RESULTS Of 1567 patients (median age: 72 [IQR, 59-79] years; females: 46.1%) included in the analysis, 78 patients (5.0%) had an in-hospital adverse outcome. The rate of an adverse outcome was higher in patients with a heart rate ≥100 bpm (7.6%) and ≥110 bpm (8.3%) compared to patients with a heart rate <100 bpm (3.0%). A heart rate ≥100 bpm and ≥110 bpm was associated with a 2.7 (95% CI 1.7-4.3) and 2.4-fold (95% CI 1.5-3.7) increased risk for an adverse outcome, respectively. Receiver operating characteristics analysis revealed a similar area under the curve with regard to an adverse outcome for all scores and algorithm (ESC 2019 algorithm, modified FAST and Bova score) if calculated with a heart rate threshold of ≥100 bpm or of ≥110 bpm. CONCLUSIONS Defining tachycardia by a heart rate ≥100 bpm is sufficient for risk stratification of normotensive patients with acute PE. The use of different heart rate thresholds for calculation of scores and algorithm does not appear necessary.

Abstract
BACKGROUND Direct oral anticoagulants are recommended for the treatment of cancer-associated thrombosis (CAT) as an alternative to low-molecular-weight heparin (LMWH), but an increased bleeding risk in patients with gastrointestinal cancer was reported. The Caravaggio study compared apixaban and dalteparin for the treatment of patients with CAT. Here we describe sites of bleeding, associated cancer sites, clinical presentation, and course of major bleeding in patients included in the Caravaggio study. METHODS The Caravaggio study was a multinational, randomized, open-label, noninferiority study. Bleeding events and the severity of major bleedings were adjudicated by a committee unaware of treatment allocation using predefined criteria; for the purpose of this analysis, data were analyzed in the safety population. RESULTS Major bleeding occurred in 22 of 576 patients on apixaban (3.8%) and in 23 of 579 patients on dalteparin (4.0%). The sites of major bleeding and their distribution according to the type of cancer were similar between the two treatment groups. Major bleeding occurred in nine patients with gastrointestinal cancer in each treatment group. The clinical presentation of major bleeding was severe or fatal in 6 patients on apixaban and in 5 patients on dalteparin, while the clinical course was severe in 5 patients on apixaban and in 7 patients on dalteparin. CONCLUSION Apixaban is a safe alternative to LMWH for the treatment in patients with CAT. No excess in gastrointestinal bleeding was observed in patients who received apixaban, including those with gastrointestinal cancer.

Abstract
BACKGROUND In this randomized trial, currently utilized standard treatments were compared with enoxaparin for the prevention of venous thromboembolism (VTE) in patients with intracerebral hemorrhage (ICH). METHODS Enoxaparin (0.4 mg daily for 10 days) was started after 72 h from the onset of ICH. The primary outcome was symptomatic or asymptomatic deep venous thrombosis as assessed by ultrasound at the end of study treatment. The safety of enoxaparin was also assessed. We included the results of this study in a meta-analysis of all relevant studies comparing anticoagulants with standard treatments or placebo. RESULTS PREVENTIHS was prematurely stopped after the randomization of 73 patients, due to the low recruitment rate. The prevalence of any VTE at 10 days was 15.8% in the enoxaparin group and 20.0% in the control group (RR 0.79 [95% CI 0.29-2.12]); 2.6% of enoxaparin and 8.6% of standard therapy patients had severe bleedings (RR 0.31 [95% CI 0.03-2.82]). When these results were meta-analyzed with the results of the selected studies (4,609 patients; 194 from randomized trials), anticoagulants were associated with a nonsignificant reduction in any VTE (OR 0.81; 95% CI 0.43-1.51), in pulmonary embolism (OR 0.53; 95% CI, 0.17-1.60), and in mortality (OR 0.85; 95% CI 0.64-1.12) without increase in hematoma enlargement (OR 0.97; 95% CI, 0.31-3.04). CONCLUSIONS In patients with acute ICH, the use of anticoagulants to prevent VTE was safe but the overall level of evidence was low due to the low number of patients included in randomized clinical trials.

Abstract
BACKGROUND In patients on anticoagulant treatment, the major bleeding (MB) definition released by the International Society of Thrombosis and Haemostasis (ISTH) is widely accepted. However, this definition identifies MBs with highly variable short-term risk of death. OBJECTIVES The study aims were to derive and validate a classification of ISTH-defined MBs for the risk of short-term death. METHODS Consecutive patients admitted for ISTH-defined MB occurring while on treatment with oral anticoagulants were included in the study and divided into a derivation and a validation cohort. Death within 30 days was the primary study outcome. RESULTS Among 1077 patients with MB, 64/517 and 63/560 patients in the derivation and validation cohort died, respectively. In the derivation cohort, Glasgow coma scale (GCS) <14 and shock were predictors of death; critical site bleeding and hemoglobin decrease ≥2 g/dL, or transfusion ≥ 2 units were not. GCS <14 (hazard ratio [HR], 8.67; 95% confidence interval [CI], 3.93-19.13) was predictor of death in intracranial hemorrhage (ICH) and shock at admission (HR, 4.84; 95% CI, 2.01-11.70) and pericardial bleeding (HR, 11.37; 95% CI, 1.33-97.31) in non-ICH MBs. The predictive value of GCS <14 in ICH and shock and pericardial bleeding in non-ICH MBs was confirmed in the validation cohort. None of the patients with isolated ocular or articular bleeding died. A prognostic classification of ISTH-defined MBs for the risk of short-term death is proposed as "serious," "severe," and "life-threatening" (ICH with GCS <14 or non-ICH with shock) MBs. CONCLUSION According to our study, ISTH-defined MBs can be stratified for the risk of death within 30 days.

Abstract
Background
Data on the use of direct oral anticoagulants (DOACs) in patients with upper extremities deep vein thrombosis (UEDVT) are limited.
Purpose
To assess the effectiveness and safety of DOACs in the treatment of UEDVT.
Methods
Data on patients with an objective diagnosis of acute UEDVT treated with DOACs were merged from prospective cohorts of patients with venous thromboembolism (VTE). Study outcomes were recurrent VTE and major bleeding (MB) occurring during DOAC treatment.
Results
Overall, 132 patients were included: mean age was 47.7±18.0 years (range 18 to 97), males were 42.4%. Twenty-seven percent of patients had 2 or more risk factors for VTE, 29.5% had UEDVT complicating a central venous line or after pacemaker implantation (Table). Ninety-two patients (70%) were managed as outpatients. Increased age (OR 1.03, 95% CI 1.0–1.05) and anemia (OR 1.35, 95% CI 1.07–1.70) were associated with in-patient management. Among patients treated with apixaban (40) or rivaroxaban (85) loading dose was used in 72%; in patients treated with dabigatran (5) or edoxaban (2) mean heparin pre-treatment was 8 days. DOACs were started after 1 month from UEDVT diagnosis in 12.9% of patients; active cancer was a main predictor for delayed initiation (OR 22.2, 95% CI 5.8–84.4). Mean treatment duration in patients with a scheduled stop was 4.9 months, while mean followup in those who continued DOACs was 9.3 months. No recurrence of VTE nor MBs occurred during DOAC treatment; one patient had acute limb ischemia (1.38% patient-year), 7 clinically relevant non-MBs (3 genital, 2 epistaxis, 1 gingival, 1 genital bleeding plus epistaxis; 10.51% patient-year), 5 deaths (4 cancer, 1 advanced age; 9.69% patient-year).
Conclusions
Our data support the effectiveness and safety of DOACs for the treatment of acute UEDVT. Further studies are required to confirm these findings.

Abstract
The effect of renal impairment (RI) on risk of bleeding and recurrent thrombosis in cancer patients treated with direct oral anticoagulants for venous thromboembolism (VTE) is undefined. We run a prespecified analysis of the randomized Caravaggio study to evaluate the role of RI as risk factor for bleeding or recurrence in patients treated with dalteparin or apixaban for cancer-associated VTE. RI was graded as moderate (creatinine clearance between 30-59 ml/minute; 275 patients) and mild (between 60-89 ml/minute; 444 patients).
In 1142 patients included in this analysis, the incidence of major bleeding was similar in patients with moderate vs. no or mild RI (HR 1.06, 95% CI 0.53-2.11), with no difference in the relative safety of apixaban and dalteparin. Recurrent VTE was not different in moderate vs. no or mild RI (HR 0 .67, 95% CI 0.38-1.20); in moderate RI, apixaban reduced recurrent VTE compared to dalteparin (HR 0.27, 95% CI 0.08-0.96; P for interaction 0.1085). At multivariate analysis, no association was found between variation of renal function over time and major bleeding or recurrent VTE. Advanced or metastatic cancer was the only independent predictor of major bleeding (HR 2.84, 95% CI 1.20-6.71), with no effect of treatment with apixaban or dalteparin.
In our study in cancer patients treated with apixaban or dalteparin, moderate RI was not associated with major bleeding or recurrent VTE. In patients with moderate renal failure, the safety profile of apixaban was confirmed with the potential for improved efficacy in comparison to dalteparin.
