Background: Rheumatoid arthritis (RA) is a chronic systemic autoimmune disorder characterized by persistent inflammation leading to progressively worse disability. Janus kinase (JAK) inhibitors and tumor necrosis factor (TNF) inhibitors are pivotal in RA treatment, yet their comparative efficacy remains underexplored. Aim: This study aimed to compare the efficacy and safety of JAK inhibitors and TNF inhibitors in treating RA using data from randomized controlled trials (RCTs). Methods: A meta-analysis and outcomes analysis were based on results of the Health Assessment Questionnaire Disability Index (HAQ-DI), Clinical Disease Activity Index (CDAI), Visual Analogue Scale (VAS), and Patient Global Assessment Scale (PtGA) and other indices as incidences of venous thromboembolism (VTE) and malignancy. Results: The JAK inhibitors caused a statistically significant improvement in the HAQ-DI score [MD = 0.08, 95% CI (0.03, 0.12), p = 0.0008] compared with the TNF inhibitors. However, no significant difference was observed between the two drug classes in the CDAI score [MD = − 2.03, 95% CI (− 9.27, 5.22), p = 0.58]. JAK inhibitors were associated with an increase in the VAS score [MD = 3.62, 95% CI (0.86, 6.38), p = 0.01], but there was no significant difference in the PtGA score [MD = 1.91, 95% CI (− 3.25, 7.08), p = 0.47]. Conclusion: JAK inhibitors demonstrated superior efficacy in improving the functional status and reducing the disease activity in RA patients compared with TNF inhibitors. Both drug classes exhibited comparable safety profiles for VTE and malignancies, though JAK inhibitors had a higher risk for thromboembolism. [ABSTRACT FROM AUTHOR]

Coronavirus disease 2019 (COVID-19) is associated with an increase in venous thrombotic and cardiovascular (CV) events has been reported during hospitalization. No systematic ultrasound follow-up to evaluate sequelae was ever that took place carried out prospectively associated with the evaluation of CV morbidity-mortality at 3 months post-discharge. Consecutive patients hospitalized for COVID-19 in the Amiens-Picardie University Hospital between 1st February and 31st August 2020 were included. The primary objective was the thrombosis incidence at 3 months after hospital discharge. Thrombosis was defined as either venous thromboembolism (VTE) or a CV event (CVE: myocardial infarction (MI), stroke or peripheral arterial disease). A secondary objective was to determine the risk factors for thrombotic events. We included 498 patients (279 men; 56%) of median age 66 (55-76) years. The primary composite outcome occurred in 27 patients (5.4%); 19 patients (3.8%) presented a CVE (stroke, n = 5; MI, n = 9; and peripheral arterial disease, n = 5). Two patients (0.8%) presented VTE. Six patients (1.2%) died. In multivariate analysis, a previous CVE was associated with thrombosis (OR 3.11; 95% CI 1.17-8.24). COVID-19 was significantly associated with thrombotic events post hospital discharge. Special attention should be given to CVE in the follow-up of patients with a previous thrombotic event.

Venous thromboembolism (VTE), including both pulmonary embolism (PE) and deep vein thrombosis (DVT), is the leading cause of maternal death in developed countries. Pregnancy is associated with an increased risk of VTE due to physiologic changes during the obstetric period that promote a hypercoagulable state. Appropriate use of prophylactic anticoagulants can decrease the event rate of thrombus formation in at-risk patients. In the United States, there is not a validated risk-assessment tool for VTE in obstetric patients or a clear consensus on initiation and optimal dosing strategy for the prophylactic use of anticoagulants. This article reviews the mechanism of coagulation disturbance that leads to an increased risk of VTE in obstetric patients, as well as the available literature surrounding pharmacologic prophylaxis.

Objective: Atrial fibrillation (AF) is one of the most common arrhythmic disorders worldwide. This study aims to describe the prevalence of AF in various cities in Indonesia using single‐lead hand held electrocardiography linked to a smartphone‐based application. Methods: This is a cross‐sectional epidemiological study conducted at tertiary hospital of major cities in Indonesia, between January 2018 and July 2019. The AliveCor Kardia™ Mobile system device was used as a screening tool for AF and confirmed its finding with clinical diagnoses made by cardiologists. Results: A total of 9773 subjects were enrolled in this study. The prevalence of AF reported by the device and cardiologist was 3.2% and 3.5%, respectively. AF prevalences are equal in men than women. The majority of subjects (56%) are having low risk for stroke or systemic thromboembolism. Prevalence of risk factors such as heart failure, hypertension, diabetes, and history of stroke among AF patients were 50%, 22.9%, 31.9%, 13.5%, and 5.8%, respectively. Conclusion: The prevalence of AF at referral hospitals visitors based on smartphone diagnosis in Indonesia is 3.2%. [ABSTRACT FROM AUTHOR]

The article revisits marantic endocarditis, or non-bacterial thrombotic endocarditis (NBTE), highlighting a case series of 111 patients from the Mayo Clinic, primarily diagnosed through transesophageal echocardiography. Topics discussed include the high incidence of systemic embolism, the prevalence of mitral valve involvement, and the correlation between cancer types and significant valve regurgitation.

Background: Severe acute ischemic stroke (AIS) is mainly caused by thromboembolism originating from symptomatic carotid artery (ICA) stenosis or in the heart due to atrial fibrillation. Glycoprotein VI (GPVI), a principal platelet receptor, facilitates platelet adherence and thrombus formation at sites of vascular injury such as symptomatic ICA stenosis. The shedding of GPVI from the platelet surface releases soluble GPVI (sGPVI) into the circulation. Here, we aimed to determine whether sGPVI can serve as a local biomarker to differentiate between local atherosclerotic and systemic cardiac thromboembolism in AIS. Methods: We conducted a cohort study involving 105 patients undergoing emergency endovascular thrombectomy (EVT) for anterior circulation stroke. First, sGPVI concentrations were measured in systemic arterial plasma samples collected at the ipsilateral ICA level, including groups with significantly (≥50%) stenotic and non-stenotic arteries. A second sample, taken from the intracerebral pial circulation, was used to assess GPVI shedding locally within the ischemic brain. Results: Our analysis revealed no significant increase in systemic sGPVI levels in patients with symptomatic ≥ 50% ICA stenosis (3.2 [95% CI 1.5–5.0] ng/mL; n = 33) compared with stroke patients without significant ICA stenosis (3.2 [95% CI 2.3–4.2] ng/mL; n = 72). Additionally, pial blood samples, reflecting intravascular molecular conditions during collateral flow, showed similar sGPVI levels when compared to the systemic ICA samples in both groups. Conclusions: Our findings indicate that GPVI is not locally cleaved and shed into the bloodstream in significant amounts during hyper-acute ischemic stroke, neither at the level of symptomatic ICA nor intracranially during collateral blood supply. Therefore, sGPVI does not appear to be suitable as a local stroke biomarker despite strong evidence of a major role for GPVI-signaling in stroke pathophysiology. [ABSTRACT FROM AUTHOR]

Background Clopidogrel (CPG)-based dual antiplatelet therapy (DAPT) in combination with aspirin has been widely used before endovascular procedures for intracranial aneurysms to prevent procedural thromboembolic complication (TEC). However, the main drawback of CPG is the high proportion of hyporesponders. This study sought to investigate the usefulness of tailored DAPT using novel P2Y12 inhibitors (prasugrel or ticagrelor, (PSG/TCG)) guided by a platelet reactivity test (PRT), compared with CPG-based conventional DAPT. Method Data were extracted from PubMed, Embase, and Cochrane Central Register of Controlled Trials by two independent reviewers. A random effects model was used to investigate the procedural TEC and hemorrhagic complications (HEC) of the tailored DAPT and conventional therapy by risk ratios (RR) and 95% confidence intervals (95% CI). Additionally, we performed subgroup analyses to directly compare prasugrel/ticagrelor with CPG. Results Six studies comprising 2557 patients were included in the analysis. Compared with conventional non-tailored therapy, PRT-guided tailored DAPT with PSG/TCG was associated with a lower risk of TEC (RR 0.40, 95% CI 0.22 to 0.74, P=0.004) without increasing HEC rates. The subgroup analysis showed that the switch to PSG/TCG in CPG hyporesponders was related to a lower incidence of TEC (RR 0.46, 95% CI 0.23 to 0.95, P=0.03) without a difference in HEC, compared with maintenance of CPG in CPG responders. Conclusion Evidence from this analysis supports PRT-guided tailored DAPT (using PSG/TCG) as a better choice for preparation towards endovascular procedures to treat aneurysms. Furthermore, it suggests that PSG/TCG is not limited to the role of a substitute for CPG but may be a first-line agent for DAPT. [ABSTRACT FROM AUTHOR]

Background: Thyroid dysfunction's effects on those who have been diagnosed with atrial fibrillation have not been well investigated. We looked at how thyroid function among patients with pre-existing atrial fibrillation related to thromboembolic risk and clinical outcomes. Methods: We gathered the medical information of patients diagnosed with nonvalvular atrial fibrillation (NVAF) between 2016 and 2020 at Dongguan People's Hospital. We then assessed the correlation between thyroid dysfunction and thrombotic risk (CHA2DS2-VASc) as well as the occurrence of clinical composite endpoint (all-cause death, heart failure, systemic embolism and hemorrhage events). Results: Of 1329 patients were admitted, 82.6% were euthyroid, 7.4% had subclinical hyperthyroidism, 4.2% had subclinical hypothyroidism, and 6.7% had low triiodothyronine (T3) syndrome. Lower levels of total triiodothyronine (TT3) were linked to an increased risk of thromboembolism (P < 0.005). During a median follow-up period of 1.84 years, there were 608 clinical composite endpoint occurrences. In the adjusted model, Low T3 syndrome was linked to a higher risk of the clinical composite endpoint (HR, 1.68; 95% CI, 1.20–2.37; P < 0.05) in comparison to euthyroidism. Specifically, low T3 syndrome was linked to a higher risk of heart failure (HR, 1.52; 95%CI, 1.01–2.30; P < 0.05) and all-cause death (HR, 3.34; 95% CI, 1.76–6.36; P < 0.001). Conclusion: Low T3 syndrome are linked to an increased risk of heart failure and all-cause death in individuals with NVAF. And Patients with NVAF and low TT3 levels have a higher risk of thromboembolism. [ABSTRACT FROM AUTHOR]

Background: Interventional left atrial appendage occlusion (LAAO) mitigates the risk of thromboembolic events in nonvalvular atrial fibrillation (AF) patients with contraindication for long-term oral anticoagulation (OAC). Patients with prior stroke have a relevantly increased risk of recurrent stroke, so the effectiveness of LAAO could be reduced in this specific very high-risk patient group. Aim: This sub-study of the LAARGE registry investigates the effectiveness and safety of LAAO for secondary prevention in nonvalvular AF patients with a history of stroke. Methods: LAARGE is a prospective, non-randomised registry on the clinical reality of LAAO. The current sub-study employs data from index procedure and 1-year follow-up. Effectiveness and safety were assessed by documentation of all-cause mortality, non-fatal thromboembolism, procedure-related complications, and bleeding events. Results: A total of 638 patients were consecutively included from 38 hospitals in Germany and divided into two groups: 137 patients with a history of stroke (21.5%) and 501 patients without. Successful implantation was consistent between both groups (98.5% vs. 97.4%, p = NS), while peri-procedural MACCE and other complications were rare (0% vs. 0.6% and 4.4% vs. 4.0%, respectively; each p = NS). Kaplan–Meier estimate showed no significant difference in primary effectiveness outcome measure (freedom from all-cause death or non-fatal stroke) between both groups at follow-up (87.8% vs. 87.7%, p = NS). The incidence of transient ischemic attack or systemic embolism at follow-up was low (0% vs. 0.5% and 0.9% vs. 0%, respectively; each p = NS). Severe bleeding events after hospital discharge were rare (0% vs. 0.7%, p = NS). Conclusions: Patients with prior stroke demonstrated similar effectiveness and safety profile for LAAO as compared to patients without prior stroke. LAAO could serve as a feasible alternative to OAC for secondary stroke prevention in this selected group of nonvalvular AF patients. ClinicalTrials.gov identifier: NCT02230748.

Understanding perturbations in circulating lipid levels that often occur years or decades before clinical symptoms may enhance our understanding of disease mechanisms and provide novel intervention opportunities. Here, we assessed if polygenic scores (PGSs) for complex traits could detect lipid dysfunctions related to the traits and provide new biological insights. We constructed genome-wide PGSs (approximately 1 million genetic variants) for 50 complex traits in 7,169 Finnish individuals with routine clinical lipid profiles and lipidomics measurements (179 lipid species). We identified 678 associations (P < 9.0 × 10−5) involving 26 traits and 142 lipids. Most of these associations were also validated with the actual phenotype measurements where available (89.5% of 181 associations where the trait was available), suggesting that these associations represent early signs of physiological changes of the traits. We detected many known relationships (e.g., PGS for body mass index (BMI) and lysophospholipids, PGS for type 2 diabetes and triacyglycerols) and those that suggested potential target for prevention strategies (e.g., PGS for venous thromboembolism and arachidonic acid). We also found association of PGS for favorable adiposity with increased sphingomyelins levels, suggesting a probable role of sphingomyelins in increased risk for certain disease, e.g., venous thromboembolism as reported previously, in favorable adiposity despite its favorable metabolic effect. Altogether, our study provides a comprehensive characterization of lipidomic alterations in genetic predisposition for a wide range of complex traits. The study also demonstrates potential of PGSs for complex traits to capture early, presymptomatic lipid alterations, highlighting its utility in understanding disease mechanisms and early disease detection. Could changes in levels of circulating lipid species be predictive of disease? This study reveals that polygenic scores for a range of complex traits are associated with changes in concentration of circulating lipid species. [ABSTRACT FROM AUTHOR]

Background: Thrombophilias are characterized by excessive venous and arterial thrombosis at regular or unusual sites. It may result from inherited, acquired, or a combination. Hereditary thrombophilia (HT) is detected in 30–40% of patients with thromboembolism. Venous/arterial thrombosis is considered a multifactorial disorder, some patients may have more than one risk factor which may be transient or permanent. Objectives: Assess the clinical characteristics of patients with unprovoked thromboembolic events and the role of inherited thrombophilia as a causative or additive risk factor. Methods: 210 consecutive adult patients with unprovoked thromboembolic events were reviewed in hematology units at three tertiary Egyptian centers between September 2022 and September 2023. The diagnosis of thromboembolic events was confirmed by clinical and radiological findings. Laboratory screening for thrombophilia-associated. Results: Among our patients, 53(25.2%) patients presented with isolated DVT, followed by portal vein thrombosis, 32(15.2%) had a pulmonary embolism, and sagittal sinus thrombosis was developed in 23(10.9%) patients. Conclusion: Younger people who experience spontaneous thromboembolism run the chance of having hereditary thrombophilia; the more mutations discovered, the higher the risk of thrombosis; the lower leg and deep vein thrombosis were the most common sites. Lastly, MTHFR C677T was the most common polymorphism in Egyptians, detected in almost half of the cases. [ABSTRACT FROM AUTHOR]

Introduction. Pharmacokinetic studies have shown that rifampin reduces the levels of oral anticoagulants during the initiation of coadministration, raising concerns about an increased thrombotic risk, but there are limited comparative clinical outcomes between rifampin and warfarin compared with direct oral anticoagulants (DOACs). This study aimed to evaluate the effectiveness and safety of concurrent use of rifampin and warfarin versus DOACs, with assessments of outcome‐associated factors and oral anticoagulant (OAC) management quality. Methods. A total of 142 patients given rifampin plus warfarin (n = 56) or DOACs (n = 86) for over 7 days were included, and their clinical data and outcomes were compared. Results. The median Charlson Comorbidity Index and HAS‐BLED (hypertension, abnormal renal/liver function, stroke, bleeding history or predisposition, labile INR, elderly, drugs/alcohol concomitantly) score of the two groups were 2 and 3, respectively. The incidence rate of composite ischemic or thromboembolic events was 2.16 and 1.44 per 10,000 patient‐days in the warfarin and DOAC groups, respectively, with an adjusted hazard ratio (HR) of 0.41 (95% confidence interval [CI] 0.02–7.34). The incidence rate of composite major bleeding or clinically relevant nonmajor bleeding events was 1.58 and 1.52 per 10,000 patient‐days in the warfarin and DOAC groups, respectively, with an adjusted HR of 1.12 (95% CI 0.32–4.45). The risk of composite bleeding events increased with a higher HAS‐BLED score (HR: 1.62, 95% CI: 1.02–2.63). Moreover, 34.3% of warfarin users maintained a percent time in therapeutic range of above 50%. Furthermore, 77.9% of DOAC users received appropriate dosing. Conclusion. No significant differences were observed in terms of the incidence of thrombotic or bleeding events between the two groups during coadministration. In addition, a higher HAS‐BLED score was associated with a greater risk of bleeding events regardless of the class of OACs used. Finally, close monitoring of bleeding events should be considered.

ABSTRACT Aim(s) Design Methods Results Conclusions Implications for the Profession Reporting Method Patient or Public Contribution Trial Registration To systematically review the existing literature and address the following research question: What are the most effective techniques used to minimise adverse effects resulting from subcutaneous injections of low‐molecular‐weight heparin among patients with cardiovascular diseases?A scoping review.A comprehensive search was conducted across multiple databases, including CINAHL, PubMed, EMBASE and the Cochrane Library, from 1 February 2014 to 31 January 2024. Participants were aged 18 years or older, diagnosed with venous thromboembolism or arterial thromboembolism and had prescribed subcutaneous injections of low‐molecular‐weight heparin. The collected data were analysed following the Joanna Briggs Institute approach, and it was organised and categorised based on the main objectives of the review.Twenty studies were eligible, including 1 best practice project, 7 randomised controlled trials and 9 quasi‐experimental studies. The techniques under investigation encompassed various aspects, including the injection site, injection duration (e.g., 30 s vs. 10 s), injection method (e.g., needle insertion angle), duration of needle withdrawal after injection, pressure application time and cold pressure. Preliminary evidence suggests that techniques such as using the abdominal site and slower injection rates may help reduce adverse effects. However, the optimal parameters for injection duration, waiting time, pressure and cold application, including the duration of these applications, remain uncertain due to limitations in sample size and heterogeneity in interventions and outcome measures across the studies.Ensuring the accurate administration of low‐molecular‐weight heparin is of utmost importance as it plays a critical role in decreasing mortality rates and minimising substantial healthcare costs linked to complications arising from incorrect administration. The findings from the current review have significantly contributed to strengthening the evidence base in this field, providing more robust and reliable information.This review emphasises the significance of implementing standardised subcutaneous injection techniques for low‐molecular‐weight heparin in patients with cardiovascular disease in order to reduce complications and enhance patient outcomes.This study followed the applicable guidelines established by the PRISMA 2020 statement. The PRISMA checklist for systematic reviews was utilised for reporting purposes.There is no patient or public contribution to declare.OSF registries: osf.io/phk72 [ABSTRACT FROM AUTHOR]

Introduction Methods Results Conclusion Data on the perioperative bleeding risk associated with elevated plasma levels of direct factor Xa inhibitors (FXa inhibitors) are limited. This study examines perioperative red blood cell (RBC) loss in patients undergoing urgent surgery with a residual FXa inhibitor level exceeding 100 mcg/L and without preoperative FXa inhibitor reversal.This retrospective analysis includes data from 32 patients who underwent urgent noncardiac surgery between 2018 and 2022. This study aims to analyze perioperative RBC loss in patients undergoing urgent surgery with a residual FXa inhibitor level exceeding 100 mcg/L and without preoperative FXa inhibitor antidote‐based reversal or unspecific treatment with 4‐factor prothrombin complex concentrate (PCC). All patients were managed using a watch‐and‐wait strategy.The last determination of FXa inhibitor plasma concentration prior to surgery showed a median of 245 mcg/L (IQR 144–345), with a median time interval of 3.8 h (IQR 2.4–7.2) before incision. Median RBC loss during surgery was 49 mL (IQR 0–253), 189 mL (IQR 104–217) until POD1 and 254 mL (IQR 58–265) until POD3. Only one patient required intraoperative treatment with 4‐factor‐PCC and none required reversal with andexanet alfa. Linear regression models found no significant influence of FXa inhibitor plasma levels on intraoperative RBC loss. Rivaroxaban was associated with higher RBC loss until postoperative Day 1 compared with apixaban. No thromboembolic events were observed.Despite markedly elevated plasma concentrations of residual direct FXa inhibitors, perioperative RBC loss was limited in patients undergoing urgent noncardiac surgery. The intraoperative watch‐and‐wait strategy with selective intraoperative FXa inhibitor reversal or treatment only when required appears to be an appropriate approach. [ABSTRACT FROM AUTHOR]

Background: COVID-19 is a global pandemic that negatively affected the world economy and the health care resources. It is associated with great health impact, mortality, and long-term sequelae. Methods: History taking computed tomography of the chest and laboratory investigations including complete blood count, liver and kidney function tests, serum ferritin, C-reactive protein, and D-dimer were done. Results: A total of 246 hospitalized COVID-19 patients were enrolled. Male predominance (67.1% of the total study population) was observed. The mean age was 57.26 ± 14.08 years. Moderate cases comprised 63.8% of the total study population, 22.4% were severe cases, and 13.8% were critical cases. The mortality rate was 8.13% and 6.1% developed venous thromboembolism. Conclusion: Age, smoking, and the presence of previous pulmonary disease were among the most important factors affecting COVID-19 severity. The severity of the disease greatly influences the incidence of venous thromboembolism and the outcome of the disease. [ABSTRACT FROM AUTHOR]

Background and Aims The role of gender in decision-making for oral anticoagulation in patients with atrial fibrillation (AF) remains controversial. Methods The population cohort study used electronic healthcare records of 16 587 749 patients from UK primary care (2005–2020). Primary (composite of all-cause mortality, ischaemic stroke, or arterial thromboembolism) and secondary outcomes were analysed using Cox hazard ratios (HR), adjusted for age, socioeconomic status, and comorbidities. Results 78 852 patients were included with AF, aged 40–75 years, no prior stroke, and no prescription of oral anticoagulants. 28 590 (36.3%) were women, and 50 262 (63.7%) men. Median age was 65.7 years (interquartile range 58.5–70.9), with women being older and having other differences in comorbidities. During a total follow-up of 431 086 patient-years, women had a lower adjusted primary outcome rate with HR 0.89 vs. men (95% confidence interval [CI] 0.87–0.92; P <.001) and HR 0.87 after censoring for oral anticoagulation (95% CI 0.83–0.91; P <.001). This was driven by lower mortality in women (HR 0.86, 95% CI 0.83–0.89; P <.001). No difference was identified between women and men for the secondary outcomes of ischaemic stroke or arterial thromboembolism (adjusted HR 1.00, 95% CI 0.94–1.07; P =.87), any stroke or any thromboembolism (adjusted HR 1.02, 95% CI 0.96–1.07; P =.58), and incident vascular dementia (adjusted HR 1.13, 95% CI 0.97–1.32; P =.11). Clinical risk scores were only modest predictors of outcomes, with CHA2DS2-VA (ignoring gender) superior to CHA2DS2-VASc for primary outcomes in this population (receiver operating characteristic curve area 0.651 vs. 0.639; P <.001) and no interaction with gender (P =.45). Conclusions Removal of gender from clinical risk scoring could simplify the approach to which patients with AF should be offered oral anticoagulation. [ABSTRACT FROM AUTHOR]

The document titled "2024 ESC Guidelines for the management of atrial fibrillation developed in collaboration with the European Association for Cardio-Thoracic Surgery (EACTS)" provides comprehensive guidelines for the management of atrial fibrillation (AF). It covers various aspects of AF, including definitions, diagnostic criteria, symptoms, patient pathways, comorbidity and risk factor management, stroke prevention, rate and rhythm control, evaluation, and dynamic reassessment. The guidelines also address specific clinical settings, such as acute coronary syndromes, stroke, pregnancy, and congenital heart disease. Additionally, it discusses screening and prevention strategies for AF. The document aims to provide evidence-based recommendations to improve the care and outcomes of patients with AF.

Background: Anemia frequently occurs in patients with hip fractures and represents a risk factor that can potentially be altered. To evaluate the association between admission anemia and complications in older hip fracture patients while exploring the potential impact of anemia on complications from the perspective of overall, operation and non-operation. Methods: This retrospective study enrolled in-patients over 60 years old with hip fractures from January 2020 to November 2023. At admission, anemic patients were identified as having a hemoglobin level below 12 g/dL in females and 13 g/dL in males. Anemia was further classified as mild, moderate, or severe. Data encompassing demographics, comorbidities, medications, information on fracture and surgery, and complications were collected. Results: A total of 462/679 patients had anemia, including 348, 105, and 9 with mild, moderate, and severe anemia, respectively. A total of 281 individuals experienced complications, including 212 and 69 with and without operation, respectively. Multivariate regression analysis identified anemia as a greater risk for acute heart failure (OR = 2.056, p = 0.037, 95% CI 1.043–4.052) than non-anemia. Moderate to severe anemia was a significant risk factor for any complication (OR = 1.584, p = 0.028, 95% CI 1.050–2.390), ≥ 2 (OR = 2.364, p = 0.001, 95% CI 1.443–3.872) or 3 (OR = 2.311, p = 0.022, 95% CI 1.131–4.720) complications, delirium (OR = 2.301, p = 0.018, 95% CI 1.156–4.579), venous thromboembolism (OR = 2.031, p = 0.042, 95% CI 1.025–4.025), and acute heart failure (OR = 2.095, p = 0.016, 95% CI 1.145–3.834), compared with mild to non-anemia. Similar results were observed in operated patients, while anemia and its severity were not associated with complications in non-operated patients. Conclusion: Moderate to severe anemia caused complications in elderly hip fracture patients, but it was not observed in non-operated individuals. These findings would support orthopedic physicians' hierarchical management of anemic patients. [ABSTRACT FROM AUTHOR]

Background: Stroke and thromboembolism (TE) are significant complications in patients with atrial fibrillation (AF) and heart failure (HF). The impact of ejection fraction status on these risks remains unclear. This study aims to compare the risk of stroke and TE in patients with AF and HF with preserved (HFpEF) or reduced (HFrEF) ejection fraction. Methods: Literature search of PubMed, Embase, and Scopus databases was done for studies in adult (20 years or more) population of AF patients. Included studies had reported on the incidences of stroke and/or TE in patients with AF and associated HF with reduced ejection fraction (HFrEF) and preserved ejection fraction (HFpEF). Cohort (prospective and retrospective), case-control studies, and studies that were based on secondary analysis of data from a trial were eligible for inclusion. Methodological quality was assessed using the Newcastle Ottawa Scale (NOS). Pooled hazard ratio (HR) with 95% confidence intervals (CI) were reported. Exploratory analysis was conducted based on the different cut-offs used to define HFrEF and HFpEF. Results: Twenty studies were analyzed. In the overall analysis, HFrEF in AF patients was associated with a significantly reduced risk of stroke and systemic TE (HR 0.88, 95% CI: 0.81, 0.96; n = 20, I2 = 86.6%), compared to HFpEF. However, most studies showed comparable risk of stroke among the two groups of patients except for two studies that had documented significantly reduced risk. Upon doing the sensitivity analysis by excluding these two studies, we found similar risk among the two group of subjects and with no heterogeneity (HR 1.01, 95% CI: 0.99, 1.03; n = 18, I2 = 0.0%). Exploratory analysis also showed that the risk of stroke and systemic thromboembolism was similar between those with HFpEF and HFrEF. Conclusion: The findings suggest that there is no significantly different risk of stroke and systemic thromboembolism in cases of AF with associated HFpEF or HFrEF. The finding does not support integration of left ventricular ejection fraction into stroke risk assessments. [ABSTRACT FROM AUTHOR]

Background: Multiple studies have linked COVID-19 to a higher incidence of thromboembolic disorders. However, the association of COVID-19 with other potentially life-threatening complications, such as splanchnic vein thrombosis, is less well understood. This study aims to assess the prevalence, patient characteristics, clinical presentation, and outcomes of patients with portal vein thrombosis (PVT) and COVID-19. Methods: This was a retrospective observational study. From all positive patients for a reverse-transcription polymerase chain reaction (RT-PCR) swab test from March 2020 to June 2020, we included those who were older than 18 years, had received abdominal contrast-enhanced computed tomography (CT) in the 6 months following the positive RT-PCR swab, and had no previously known splanchnic vein thrombosis. Results: A total of 60 patients with abdominal CT were selected from all those positive for SARS-CoV-2 (n = 2987). The prevalence of PVT was 3/60 (5%). The mean age was 66.1 ± 16.5 years and 51.7% were male. In two of the three patients, there was no underlying pathology as a risk factor for PVT and one of them presented cirrhosis. The number of days from the start of COVID-19 symptoms until the PVT diagnosis were 21, 12, and 10 days. Anticoagulation treatment achieved recanalization in 100% of cases. During a mean follow-up of 803 days, none of the patients experienced long-term complications. Conclusions: Portal vein thrombosis is uncommon, and its incidence may be higher in COVID-19 patients. A greater understanding of the features of this disease in the context of COVID-19 could aid towards its diagnosis and allow for early detection and management. [ABSTRACT FROM AUTHOR]

Acute pulmonary embolism (PE) is a leading cause of mortality. Not only is PE associated with short-term mortality, but up to ~20% of patients might suffer from long-term consequences such as post-PE syndrome and chronic thromboembolic pulmonary hypertension. Current risk stratification tools poorly predict those who are at risk for short-term deterioration and those who develop long-term consequences. Traditionally, systemic thrombolysis has been considered the first-line therapy for patients with high-risk PE without contraindications; however, it comes with the risk of major bleeding (notably intracranial hemorrhage). The use of catheter-directed interventions (embolectomy or thrombolysis) has been increasing owing to their low bleeding risk; however, randomized trial data supporting their efficacy in improving clinical outcomes are limited. In this review, we highlight the evidence supporting the available advanced therapies for high- and intermediate-risk PE and summarize the ongoing trials which are evaluating these therapies.

Simple Summary: The development of cancer is associated with coagulation disorders. Blood cancers should be particularly associated with hypercoagulability and thus thromboembolic complications. An essential finding of this study is that arterial thromboembolism (myocardial infarction or stroke) occurs significantly more often than venous thromboembolism (pulmonary embolism or/and thrombosis) preceding the diagnosis of hematological malignancy. Interestingly, venous thromboembolism occurs significantly more often in acute leukemia (myeloid or lymphocytic) and chronic myeloproliferative disease. However, the chance of venous thromboembolism is increased before and after the diagnosis of myeloproliferative disease. More research is needed on the relationship between venous thromboembolism development and myeloproliferative disease progression. Objectives. Venous and arterial thromboembolism (VTE/ATE) often coexist with onco-hematologic diagnosis. This study aimed to assess the time relationship between the diagnosis of VTE/ATE and blood cancers. The second aim was to identify VTE/ATE risk factors related to the type of hematology disease and cardiac history. Methods. A total of 1283 patients underwent cardio-oncology evaluation at the Institute of Hematology and Transfusion Medicine in Warsaw from March 2021 through March 2023 (2 years), and 101 (7.8%) cases were identified with VTE/ATE. Results. ATE compared with VTE significantly occurred more often before the diagnosis and treatment of hematologic malignancy: 33/47 (70.2%) vs. 15/54 (27.8%), p < 0.0001. The risk of a VTE episode is exceptionally high in the first months after the diagnosis of an onco-hematological disease and the initiation of anticancer treatment. The higher frequency of VTE was associated with acute myeloid leukemia (17 cases/270 patients/6.30%/p = 0.055), acute lymphocytic leukemia (7 cases/76 patients/9.21%/p = 0.025), and chronic myeloproliferative disease (7 cases/48 patients/14.58%/p = 0.0003). Only the risk of VTE was significantly increased before (OR = 6.79; 95% CI: 1.85–24.95; p = 0.004) and after diagnosis of myeloproliferative disease (OR = 3.12; 95% CI: 1.06–9.16; p = 0.04). Conclusions. ATEs occur more often than VTE before a diagnosis of blood cancer. The risk of VTE is exceptionally high before and after diagnosis of chronic myeloproliferative disease.

Introduction: COVID-19 triggers prothrombotic and proinflammatory changes, with thrombotic disease prevalent in up to 30% SARS-CoV-2 infected patients. Early work suggests that aspirin could prevent COVID-19 related thromboembolic disorders in some studies but not others. This study leverages data from the largest integrated healthcare system in the United States to better understand this association. Our objective was to evaluate the incidence and risk of COVID-19 associated acute thromboembolic disorders and the potential impact of aspirin. Methods: This retrospective, observational study utilized national electronic health record data from the Veterans Health Administration. 334,374 Veterans who tested positive for COVID-19 from March 2, 2020, to June 13, 2022, were included, 81,830 of whom had preexisting aspirin prescription prior to their COVID-19 diagnosis. Patients with and without aspirin prescriptions were matched and the odds of post-COVID acute thromboembolic disorders were assessed. Results: 10.1% of Veterans had a documented thromboembolic disorder within 12 months following their COVID-19 diagnosis. Those with specific comorbidities were at greatest risk. Preexisting aspirin prescription was associated with a significant decrease risk of post-COVID-19 thromboembolic disorders, including pulmonary embolism (OR [95% CI]: 0.69 [0.65, 0.74]) and deep vein thrombosis (OR [95% CI]: 0.76 [0.69, 0.83], but an increased risk of acute arterial diseases, including ischemic stroke (OR [95% CI]: 1.54 [1.46, 1.60]) and acute ischemic heart disease (1.33 [1.26, 1.39]). Conclusions: Findings demonstrated that preexisting aspirin prescription prior to COVID-19 diagnosis was associated with significantly decreased risk of venous thromboembolism and pulmonary embolism but increased risk of acute arterial disease. The risk of arterial disease may be associated with increased COVID-19 prothrombotic effects superimposed on preexisting chronic cardiovascular disease for which aspirin was already prescribed. Prospective clinical trials may help to further assess the efficacy of aspirin use prior to COVID-19 diagnosis for the prevention of post-COVID-19 thromboembolic disorders. [ABSTRACT FROM AUTHOR]

Introduction: Anticoagulants have been discovered and developed over past 100 years. At the beginning unfractionated heparin found its applications, just later to fade into the background of newer and more effective drugs. Patients have been treated with more and more progressive medications -- Low-Molecule-Weight Heparin (LMWH), Vitamin K Antagonists (VKA) and Novel Oral Anticoagulants (NOAC). All of them have many indications but most importantly they are used in prophylaxis and treatment of venous thromboembolism (VTE). Scientists and physicians have been working for years to come up with the perfect drug that has fewer contraindications, side effects and doesn't need continuous anticoagulant monitoring. As for today, deemed a turning point in anticoagulant therapy are inhibitors of factor XI. It is a ground-breaking innovation as it ensures high prevention of thrombotic episodes and guarantees intact physiological hemostasis. Current State of Knowledge: The coagulation cascade and molecules part taking in that have been discovered and described extensively and in detail. Historically, the demand for anticoagulants was always a burning subject. A huge progress has been made in the last one hundred years. Treatment which clinicians are using currently is a combination of drugs used in the past and the novel forms. Unfractionated heparin is the oldest out of all and despite its simple action mechanism and adverse effects, is still a requested drug. Its lighter form, low-molecule-weight-heparin (LMWH) is an enhancement to the previous treatment due to its higher bioavailability and fewer side effects. Vitamin K antagonists (VKAs) are widely spread in medical environment thanks to their expanded mechanism of action, oral administration and reversibility of their overdose, as well as their well-developed anti-side effect therapy. Novel Oral Anticoagulants (NOACs) have been introduced to the market about 10 years ago. In spite of NOACs short period of clinical use, they were a huge change to the previous treating methods. No need of constant checking the coagulation times was a great convenience to both patients and doctors. Currently, the newest innovation in anticoagulant therapy are inhibitors of factor XI. Even though it still undergoes clinical trials, the outcome is promising for the future. Summary: The present article discusses history of anticoagulant drugs, their mechanism of action and usage but also focuses on the recent perspectives and developments as new anticoagulant drugs are being put to the test in therapeutic trials. The review underlines the importance and a big demand for improvements in old therapeutic methods and exploring the new, more suitable ones. [ABSTRACT FROM AUTHOR]

Venous thrombosis and pulmonary embolism (venous thromboembolism) are important causes of morbidity and mortality worldwide. In patients with venous thromboembolism, thrombi obstruct blood vessels and resist physiological dissolution (fibrinolysis), which can be life threatening and cause chronic complications. Plasminogen activator therapy, which was developed >50 years ago, is effective in dissolving thrombi but has unacceptable bleeding risks. Safe dissolution of thrombi in patients with venous thromboembolism has been elusive despite multiple innovations in plasminogen activator design and catheter-based therapy. Evidence now suggests that fibrinolysis is rigidly controlled by endogenous fibrinolysis inhibitors, including α2-antiplasmin, plasminogen activator inhibitor-1, and thrombin-activable fibrinolysis inhibitor. Elevated levels of these fibrinolysis inhibitors are associated with an increased risk of venous thromboembolism in humans. New therapeutic paradigms suggest that accelerated and effective fibrinolysis may be achieved safely by therapeutically targeting these fibrinolytic inhibitors in venous thromboembolism. In this article, we discuss the role of fibrinolytic components in venous thromboembolism and the current status of research and development targeting fibrinolysis inhibitors. [ABSTRACT FROM AUTHOR]

This narrative review investigates the use of direct oral anticoagulants to treat patients undergoing surgical and nonsurgical procedures and the most effective management strategies for these medications based on the type of procedure, including elective, emergent, urgent, or semiurgent. Importance: Direct oral anticoagulants (DOACs), comprising apixaban, rivaroxaban, edoxaban, and dabigatran, are commonly used medications to treat patients with atrial fibrillation and venous thromboembolism. Decisions about how to manage DOACs in patients undergoing a surgical or nonsurgical procedure are important to decrease the risks of bleeding and thromboembolism. Observations: For elective surgical or nonsurgical procedures, a standardized approach to perioperative DOAC management involves classifying the risk of procedure-related bleeding as minimal (eg, minor dental or skin procedures), low to moderate (eg, cholecystectomy, inguinal hernia repair), or high risk (eg, major cancer or joint replacement procedures). For patients undergoing minimal bleeding risk procedures, DOACs may be continued, or if there is concern about excessive bleeding, DOACs may be discontinued on the day of the procedure. Patients undergoing a low to moderate bleeding risk procedure should typically discontinue DOACs 1 day before the operation and restart DOACs 1 day after. Patients undergoing a high bleeding risk procedure should stop DOACs 2 days prior to the operation and restart DOACs 2 days after. With this perioperative DOAC management strategy, rates of thromboembolism (0.2%-0.4%) and major bleeding (1%-2%) are low and delays or cancellations of surgical and nonsurgical procedures are infrequent. Patients taking DOACs who need emergent (<6 hours after presentation) or urgent surgical procedures (6-24 hours after presentation) experience bleeding rates up to 23% and thromboembolism as high as 11%. Laboratory testing to measure preoperative DOAC levels may be useful to determine whether patients should receive a DOAC reversal agent (eg, prothrombin complex concentrates, idarucizumab, or andexanet-α) prior to an emergent or urgent procedure. Conclusions and Relevance: When patients who are taking a DOAC require an elective surgical or nonsurgical procedure, standardized management protocols can be applied that do not require testing DOAC levels or heparin bridging. When patients taking a DOAC require an emergent, urgent, or semiurgent surgical procedure, anticoagulant reversal agents may be appropriate when DOAC levels are elevated or not available.

Background Aims Methods Content Conclusions Catheter‐related thrombosis (CRT) is one of the major complications affecting patients with indwelling venous catheters, usually involving the upper extremity deep venous system. This condition can lead to potentially life‐threatening complications such as pulmonary embolism and sepsis. The risk of developing CRT varies depending on type of catheters and patient characteristics. Despite advances in materials and technologies, the actual incidence of CRT is still considerable. Available evidence on CRT management remains controversial, and clinical guidelines base their recommendations on data from non‐catheter related upper extremity or lower extremity deep venous thromboses.This narrative review aims to describe the epidemiology of CRT, to review the available evidence on its management and to highlight the current unmet needs.No formal search strategy was applied for the revision of the literature. The main sources of information used were Medline and guidelines from international societies.The management of CRT requires a careful balance between the risk of thrombus progression, recurrent events, and systemic embolization and the increased bleeding risk in often fragile patients. Open issues include the optimal management of the catheter and the type and duration of anticoagulant therapy. Direct oral anticoagulants are increasingly prescribed, representing an important alternative to the standard of care low molecular weight heparins in selected cases. The development of new anticoagulant drugs such as factors XI and XII inhibitors may offer further advantages in this context.The management of CRT is still challenging with constant need for updated evidence to support tailored approaches.

Background: Acute pulmonary embolism (APE) is a major type of venous thromboembolism (VTE) with a high risk of mortality and disability. There is a lack of biomarkers for APE to indicate deteriorating development and predict adverse outcomes. This study evaluated the significance of miR-150-5p in APE aiming to explore a novel potential biomarker for APE. Methods: The study enrolled APE (n = 137) and deep wein thrombosis (DVT, n = 67) patients and collected plasma samples from all study subjects. The expression of miR-150-5p was analyzed by PCR and its significance in screening APE and pulmonary arterial hypertension (PAH) was assessed by receiver operating curve (ROC) and logistic analyses. The study established oxidized low-density lipoprotein (ox-LDL)-induced human venous endothelial cells (HUVECs). Through cell transfection combined with cell counting kit-8 (CCK8), flow cytometry, and enzyme-linked immunosorbent assay (ELISA), the effect of miR-150-5p on ox-LDL-induced HUVEC injury was evaluated. Results: Significant downregulation of miR-150-5p was observed in the plasma of APE patients compared with DVT patients (P < 0.0001). The plasma miR-150-5p levels in APE patients occurred PAH was much lower than in patients without PAH (P < 0.0001). Reducing miR-150-5p distinguished APE patients from DVT patients (AUC = 0.912) and was identified as a risk factor for the occurrence of PAH in APE patients (OR = 0.385, P = 0.010). In HUVECs, oxidized low-density lipoprotein (ox-LDL) caused inhibited cell proliferation, enhanced apoptosis, increased pro-inflammatory cytokines, reactive oxygen species (ROS), malondialdehyde (MDA), and decreased superoxide dismutase (SOD). Overexpressing miR-150-5p could promote proliferation, inhibit apoptosis, and alleviate inflammation and oxidative stress of ox-LDL-treated HUVECs. Conclusions: Downregulated plasma miR-150-5p served as a diagnostic biomarker for APE and predicted the predisposition of PAH in APE patients. Overexpressing miR-150-5p could alleviate ox-LDL-induced endothelial cell injury in HUVECs. [ABSTRACT FROM AUTHOR]

We compared the risks and benefits of COVID-19 vaccines using a causal pathway analysis to weigh up possible risk factors of thromboembolic events post-vaccination. The self-controlled case series (SCCS) method examined the association between thromboembolic events and vaccination while a case-control study assessed the association between thromboembolic events and COVID-19, addressing under-reported infection data issues. The net vaccine effect was estimated using results from SCCS and case-control studies. We used electronic health record data from Corewell Health (16,640 subjects in SCCS and 106,143 in case-control). We found increased risks of thromboembolic events post-vaccination (incidence rate ratio: 1.19, 95% CI: [1.08, 1.31] after the first dose; 1.22, 95% CI: [1.11, 1.34] after the second dose). Vaccination attenuated infection-associated thromboembolic risks (odds ratio: 4.65, 95% CI: [4.18, 5.17] in unvaccinated vs 2.77, 95% CI: [2.40, 3.24] in vaccinated). After accounting for vaccine efficacy and protection against infection-associated thromboembolic events, vaccination decreases thromboembolic event risk, especially during high infection rate periods.

Background and Aims Studies have suggested that statins may be associated with reduced risk of venous thromboembolism (VTE). The aim of the current study was to assess the evidence regarding the comparative effect of all lipid-lowering therapies (LLT) in primary VTE prevention. Methods After a systematic search of PubMed, CENTRAL, and Web of Science up until 2 November 2022, randomized controlled trials (RCT) of statins (high- or low-/moderate-intensity), ezetimibe, or proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i) were selected. An additive component network meta-analysis to compare VTE risk during long-term follow-up across different combinations of LLT was performed. Results Forty-five RCTs (n = 254 933 patients) were identified, reporting a total of 2084 VTE events. Compared with placebo, the combination of PCSK9i with high-intensity statin was associated with the largest reduction in VTE risk (risk ratio [RR] 0.59; 95% confidence interval [CI] 0.43–0.80), while there was a trend towards reduction for high-intensity (0.84; 0.70–1.02) and low-/moderate-intensity (0.89; 0.79–1.00) statin monotherapy. Ezetimibe monotherapy did not affect the VTE risk (1.04; 0.83–1.30). There was a gradual increase in the summary effect of VTE reduction with increasing intensity of the LLT. When compared with low-/moderate-intensity statin monotherapy, the combination of PCSK9i and high-intensity statin was significantly more likely to reduce VTE risk (0.66; 0.49–0.89). Conclusions The present meta-analysis of RCTs suggests that LLT may have a potential for VTE prevention, particularly in high-intensity dosing and in combination therapy. [ABSTRACT FROM AUTHOR]

Background: Low albumin level is a risk factor for thromboembolic events in patients with NS (nephrotic syndrome). However, little is known about the proportion and characteristics of patients with NS who experience thromboembolic events with relatively high albumin levels (≥ 25 g/L). Therefore, we explored the features of this specific group of patients. Methods: This study included all hospitalized patients in our center for the past 10 years who had diagnoses of NS and relevant thromboembolic events. We divided them into 2 groups based on their serum albumin level when the thromboembolic event occurred. The clinical data were analyzed with SPSS software. Results: There were 312 patients enrolled in our study. Eighty-four (26.9%) of them had relatively high albumin levels (≥ 25 g/L). Patients with NS with high albumin levels had significantly lower levels of 24-h proteinuria (P < 0.01) and a higher rate of autoimmune disease (P = 0.03) than the low-albumin group. Membranous nephropathy (MN) was the most frequent pathological type of NS in patients with thromboembolic events, regardless of their albumin level. There were significantly fewer patients with anti-PLA2R (M-type phospholipase A2 receptor)-positive MN in the high-albumin group than in the low-albumin group (P < 0.01). Conclusions: Our study found that there was still a high risk for patients with NS and relatively high albumin levels to develop thromboembolic events. [ABSTRACT FROM AUTHOR]

Activated partial thromboplastin time (aPTT)-based clot waveform analysis (CWA) is a plasma-based global haemostatic assay. Elevated CWA parameters have been associated with hypercoagulability in venous thromboembolism, but its role in arterial thrombotic disease is uncertain. This study aims to explore the relationship between aPTT-based CWA and acute myocardial infarction (AMI) and its complications. In a retrospective cohort study of patients with AMI who underwent emergency cardiac catheterisation, pre-procedural aPTT and CWA parameters—min1, min2 and max2 were measured. These were compared against a control group of patients, consisting of patients who underwent elective orthopaedic and urological procedures. Within the AMI cohort, we also compared aPTT and CWA parameters of those with and without clinical complications of AMI. Results: Compared to controls (N = 109), patients with AMI (N = 214) had shorter aPTT (26.7 ± 3.3 s vs 27.9 ± 1.7 s, P < 0.001) and higher CWA parameters (min1: 6.11 ± 1.40%/s vs 5.58 ± 1.14%/s; min2: 0.98 ± 0.23%/s2 vs 0.90 ± 0.19%/s2; max2: 0.81 ± 0.20%/s2 vs 0.74 ± 0.16%/s2, all P ≤ 0.001). There was an increased incidence of elevated CWA parameters, in the AMI group, with odds ratio (OR) of 2.06 [95% CI 1.10–3.86], 2.23 (95% CI 1.18–4.24) and 2.01 (95% CI 1.07–3.77) for min1, min2 and max2, respectively. Similarly, elevated min1 and min2 were both individually associated with the presence of adverse outcomes of AMI, both with ORs of 2.63 (95% CI 1.24–5.59). Elevated aPTT-based CWA parameters are significantly associated with the occurrence of AMI and its complications. These findings identify the potential utility of CWA as risk and prognostic markers for AMI and warrants future works. [ABSTRACT FROM AUTHOR]

Background: Although healthy sleep patterns have been linked to a lower risk of cardiovascular disease in earlier research, it is unclear how beneficial they are for venous thromboembolism (VTE). Aim: This research aimed to examine the correlation between sleep patterns, genetic susceptibility, and VTE. Methods: In the UK Biobank cohort, healthy sleep behaviors were defined as early chronotype, 7–8 hours of sleep each day, no snoring, infrequent insomnia, and infrequent daytime sleepiness. Each of the five criteria was given 1 point, creating a healthy sleep score ranging from 0 to 5. Cox proportional hazards regression models were utilized to examine the associations between genetic susceptibility, healthy sleep score and VTE. Results: The UK Biobank study included 384,758 participants aged 56.6 ± 8.0 years. After a median of 11.9 years of follow-up, 8,885 (2.3%) participants were diagnosed with VTE. A healthy sleep score inversely affected VTE risk. For participants with a score of 5, the hazard ratio of VTE was 0.813 (95% confidence interval: 0.758–0.873, P<0.001) compared to those with a score ≤2. Early chronotype, sleeping 7–8 hours each day, infrequent insomnia, and infrequent daytime sleepiness were significantly associated with a 7.9%, 8.3%, 5.1%, and 20.7% lower risk of VTE, respectively. In addition, the correlation between sleep pattern and the incidence of VTE was consistent, regardless of genetic susceptibility (P for interaction = 0.366). Conclusions: Our secondary analysis of a large-scale prospectively gathered registry revealed that individuals with a healthy sleep pattern are significantly correlated with lower risk of developing VTE, irrespective of genetic susceptibility.

ABSTRACT Objective Design Setting Population Methods Main Outcome Measures Results Conclusions Trial Registration Uncertainty surrounds the risk–benefit of low‐molecular‐weight heparin to prevent postpartum venous thromboembolism (VTE). Data from randomised clinical trials (RCT) are critically needed, but recent feasibility studies in North America yielded low participation rates, with <1 enrolment per month per centre. Our aim was to assess the feasibility of a trial of postpartum short‐term enoxaparin in Europe.Pragmatic, open‐label pilot randomised controlled trial (RCT).Swiss tertiary hospital.Postpartum women, within 48 h of delivery, deemed at intermediate risk of VTE with at least one major risk factor (morbid obesity, thrombophilia, emergency caesarean section, pre‐eclampsia, preterm delivery, intrauterine growth restriction or systemic peripartum infection) and/or at least two minor risk factors.Participants were randomised to enoxaparin 40–60 mg once daily for 10 days or no treatment, with a 90‐day follow‐up.Participation rate and study acceptance (randomised participants among women in whom informed consent was sought).Recruitment was open for 25 weeks in 2022. Among 1504 postpartum women, 480 were eligible and 77 were randomised. The recruitment rate was 3.1 per week (13.3 per month) and the study acceptance was 23.8%. At 3 months, there was no VTE event, but one major, one nonmajor obstetrical bleeding and one surgical site complication, all in the enoxaparin group.This pilot RCT of postpartum thromboprophylaxis set in Switzerland yielded greater participation rate and acceptance than previous attempts in North America. It calls for a large, international, collaborative trial to guide this important clinical decision.ClinicalTrial.gov identifier: NCT05878899 and NCT04153760. [ABSTRACT FROM AUTHOR]

Traumatic brain injury (TBI) presents complex management scenarios, particularly in patients requiring anticoagulation for concurrent conditions such as venous thromboembolism (VTE) or atrial fibrillation (AF). A systematic search of PubMed/MEDLINE, Embase, and the Cochrane Library databases was conducted to identify relevant studies. Inclusion criteria encompassed studies assessing the effects of anticoagulation therapy on outcomes such as re-hemorrhage, hematoma expansion, thrombotic events, and hemorrhagic events in TBI patients with subdural hematomas (SDH). This systematic review critically addresses two key questions: the optimal timing for initiating anticoagulation therapy and the differential impact of this timing based on the type of intracranial bleed, with a specific focus on subdural hematomas (SDH) compared to other types. Initially screening 508 articles, 7 studies met inclusion criteria, which varied in design and quality, precluding meta-analysis. The review highlights a significant knowledge gap, underscoring the lack of consensus on when to initiate anticoagulation therapy in TBI patients, exacerbated by the need for anticoagulation in the presence of VTE or AF. Early anticoagulation, particularly in patients with SDH, may elevate the risk of re-hemorrhage, posing a clinical dilemma. Evidence on whether the type of intracranial hemorrhage influences outcomes with early anticoagulation remains inconclusive, indicating a need for further research to tailor management strategies effectively. This review underscores the scarcity of high-quality evidence regarding anticoagulation therapy in TBI patients with concurrent conditions, emphasizing the necessity for well-designed prospective studies to elucidate optimal management strategies for this complex patient population.

Background: Safety recommendations for Janus kinase inhibitors (JAKi) issued by the European Medical Agency (EMA) in 2023 could potentially influence treatment patterns for rheumatoid arthritis (RA) drugs, but little is known about the impact of these recommendations in routine clinical care. Methods: We retrospectively analyzed the German RHADAR rheumatology database for adult patients with RA and documentation of a new therapy with a JAKi, tumor necrosis factor inhibitor (TNFi), or interleukin-6 receptor inhibitor (IL-6Ri). Data were grouped into half-yearly intervals from quarter (Q)2/2020 to Q3/2023. The period from Q4/2022 to Q1/2023 immediately followed the initial EMA endorsement of Pharmacovigilance Risk Assessment Committee (PRAC) recommendations and Q2/2023-Q3/2023 immediately followed the direct healthcare provider communication (DHPC) containing the new safety JAKi recommendations. Results: Between April 1, 2020 and September 23, 2023, 3008 newly initiated therapies for TNFi (1499 [49.8%]), JAKi (1126 [37.4%]), and IL-6Ri (383 [12.7%]) were documented by the treating physicians. JAKi were increasingly used in the first two half-year periods (from 29.7% of these therapies in Q2/2020-Q3/2020 to 46.7% in Q2/2021-Q3/2021; odds ratio [OR] 2.08; p<0.001). The proportion of initiated JAKi therapies decreased significantly after the PRAC recommendations (32.9%; OR vs peak 0.56; p=0.001) and the DHPC letter (26.1%; OR vs peak 0.40; p<0.001). JAKi were more likely to be used as >3rd-line therapy in later time periods. Conclusions: This exploratory study suggests that EMA safety recommendations for JAKi influenced treatment patterns of RA patients who received JAKi in Germany. Additional studies will be needed to confirm these findings. [ABSTRACT FROM AUTHOR]

This research letter discusses the rate of recurrence of venous thromboembolism (VTE) in patients who discontinued anticoagulation within 30 days after receiving the COVID-19 vaccine. The study found that the incidence of recurrent VTE was relatively low, with most cases occurring in patients receiving RNA-based vaccines. The majority of recurrent events happened within 12 months after discontinuation of anticoagulation. The study emphasizes the importance of individualized patient assessment when determining the duration of anticoagulant therapy after vaccination. However, the small cohort size and lack of an efficacy comparison group limit the generalizability of the findings. The authors disclose conflicts of interest, and the data from the registry is available upon request. [Extracted from the article]

Purpose Methods Results Conclusion Level of Evidence The purpose of this study was to assess the efficacy of aspirin versus low‐molecular‐weight heparin (LMWH) in preventing venous thromboembolism (VTE) following hip and knee arthroplasty.PubMed/Medline, Embase, Cochrane Library and Google Scholar databases were searched from inception till June 2024 for original trials investigating the outcomes of aspirin versus LMWH in hip and knee arthroplasty. The primary outcome was VTE. Secondary outcomes included minor and major bleeding events, and postoperative mortality within 90 days. This review was conducted per the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses guidelines.A total of 7 randomized controlled trials with 12,134 participants were included. The mean ages for the aspirin and LMWH cohorts were 66.6 (57.6–69.0) years and 66.8 (57.9–68.9) years, respectively. There was no statistically significant difference in the overall risk of VTE between the aspirin and the LMWH cohorts (odds ratio [OR]: 0.95; 95% confidence interval [CI]: 0.48–1.89; p: 0.877). A subanalysis based on the specific VTE entity (pulmonary embolism [PE] or deep venous thrombosis) showed a significantly higher PE risk for patients receiving aspirin than the LMWH cohort (OR: 1.79; 95% CI: 1.11–2.89; p: 0.017). There was no difference in minor (OR: 0.64; 95% CI: 0.40–1.04; p: 0.072) and major bleeding (OR: 0.77; 95% CI: 0.40–1.47; p: 0.424) episodes across both groups. Furthermore, subanalysis among the total knee arthroplasty group showed that the aspirin cohort was significantly more likely to suffer VTEs than their LMWH counterparts (OR: 1.55; 95% CI: 1.21–1.98; p < 0.001).This study demonstrated a significantly higher risk of PE among patients receiving aspirin compared to LMWH following hip or knee arthroplasty for osteoarthritis. Aspirin was associated with a significantly higher overall VTE risk among patients undergoing knee arthroplasty, in particular. This might suggest the inferiority of aspirin compared to LMWH in preventing VTE following such procedures.Level I. [ABSTRACT FROM AUTHOR]

There are many known risk factors for the development of deep vein thrombosis (DVT) and pulmonary thromboembolism (PTE). However, a recently observed risk factor is prolonged sitting (or immobility) for occupational dispensation. Some occupations, especially electronic information technology (IT) professionals, computer gamers, programmers, etc., are amenable to prolonged sitting periods for their work. Such a trend significantly increased in the corporate world during the covid pandemic restrictions and work-from-home policy of the IT companies. We have reported a case of the sudden death of an IT professional due to DVT and PTE. There is a conspicuous indication of the association between prolonged sitting hours and the development of DVT and PTE. This is also known as e-thrombosis. The prolonged seated immobility thromboembolic syndrome is a recently observed phenomenon in professionals having prolonged seated working styles. This paper is a case-based review of all tenets, i.e., clinical presentation, autopsy pathology, and preventive measures of the prolonged seated immobility thromboembolism associated with a sedentary working style.

Objective: To assess the impact of concomitant systemic lupus erythematosus (SLE) on the clinicopathological manifestations of thrombotic antiphospholipid syndrome (APS). Methods: This single-centre, retrospective study compared clinical and antiphospholipid antibody (aPL) data from 118 patients, 58 with SLE-associated APS (SLE-APS), and 60 with primary APS. Results: Median follow-up was 13.9 (IQR 7.7–19.3) and 8.6 years (3.5–10.6) for the SLE-APS cohort and PAPS cohort, respectively. Age at diagnosis of APS was lower in the SLE-APS cohort (mean 35.9 vs PAPS: 46.7 years; p < 0.05). Distribution of aPL subtypes was similar across cohorts. 198 thrombotic events were identified overall (index plus recurrent), with venous thromboembolism (VTE) and arterial thrombosis each occurring in just over half of patients in both cohorts. Microvascular thrombosis (12.1% vs 0%), and a mixed (any combination of venous, arterial and microvascular) thrombotic phenotype (19.0% vs 6.7%, p = 0.05) were more prevalent in SLE-APS patients. Recurrent thrombosis incidence rates (∼0.5 events/10-patient years), and Kaplan-Meier recurrence-free survival after index thrombosis, were similar. In the PAPS cohort, only: (i) triple-aPL-positivity was associated with a significantly higher recurrent thrombosis event rate (incidence rate ratio 2.22, p = 0.03) and lower recurrence-free survival after first thrombosis (log-rank test p = 0.01); (ii) lupus anticoagulant (LA)-positivity was associated with higher prevalance of arterial thrombosis (RR 2.69, p = 0.01), and lower prevlance of VTE (RR 0.48, p < 0.001), versus LA-negativity. Conclusion: Concomitant SLE does not appear to modify long-term recurrent thrombosis risk, or aPL phenotypes, in patients with APS. Triple-aPL-positivity and LA-positive status may have less influence on thrombotic outcomes in patients with SLE-APS compared to PAPS. [ABSTRACT FROM AUTHOR]

Background—Anticoagulants, such as vitamin-K antagonists (VKA) and direct oral anticoagulants (DOAC), are widely used among patients who undergo endoscopic procedures. To balance between bleeding and thromboembolic risks, careful decisions must be made about whether and for how long anticoagulants have to be stopped peri-endoscopically and if bridging is necessary. We created a tool in the electronic health records system (EHR) HIX (Microsoft) for invasive procedures to aid this decision-making. By selecting the anticoagulant indication or thrombo-embolic risk and the bleeding risk of the procedure, the tool automatically generates advice for periprocedural anticoagulant management. Objectives—This study assesses whether the tool is used properly peri-endoscopically. Secondly, it examines how many bleeding and thromboembolic events have occurred since the implementation of the tool. Methods—This retrospective study included all orders placed for endoscopies for patients using VKA or DOAC between 2018 and 2021. Results—In total, 986 endoscopies were included for analysis. In 89%, the tool was used correctly; the main error was selecting the wrong bleeding risk (7.5%). The cumulative incidence for moderate or severe bleeding events for DOAC and VKA was 2 (0.5%) and 0, respectively. The cumulative incidence of thromboembolic events for DOAC and VKA was 1 (0.2%) for each. Conclusions—This study evaluates the use of an EHR-integrated decision-making tool to aid peri-endoscopic anticoagulant management. By analysing the usage of the tool, we formulated several suggestions to improve the tool. Although this study is not a comparative one, we can conclude that the thromboembolic and major bleeding risks were low. [ABSTRACT FROM AUTHOR]

The establishment of a peripheral ECMO circuit can lead to significant arterial and venous complications in 10–30% of patients. Vascular complications, particularly acute limb ischemia, are associated with worsening overall outcomes. Limb ischemia occurs significantly more frequently in the early stages of VA ECMO than in VV ECMO. Mechanisms of limb ischemia include arterial obstruction, cannulation injury, loss of pulsatile flow, thromboembolism, venous stasis from compressive obstruction with large venous cannulas, and systemic vasoconstriction due to shock and pharmacologic vasoconstriction. The care team may use several mitigation strategies to prevent limb ischemia. Arterial and venous complications can be mitigated by careful access site selection, minimizing cannula size, placement of distal perfusion and/or outflow catheter(s), and continuous NIRS monitoring. Rapid intervention, when ischemia or compartment syndrome occurs, can reduce limb loss but may not affect the mortality and morbidity of the ECMO patient in the long term due to their underlying conditions and the etiology of the ECMO need.

There has been a rapid expansion in centers performing balloon pulmonary angioplasty (BPA) and pulmonary thromboendarterectomy (PTE) for chronic thromboembolic pulmonary hypertension (CTEPH). The purpose of this scoping review was to identify cardiothoracic imaging predictors of outcomes and to identify gaps to address in future work. A scoping review was conducted using the framework outlined by Arksey and O'Malley and Levac et al. in MEDLINE and EMBASE. The study protocol was preregistered in OSF Registries and performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews (PRISMA-ScR) guidelines. There were 1117 identified studies, including 48 involving pulmonary thromboendarterectomy (n = 25) and balloon pulmonary angioplasty (n = 23). CT was the most common preoperative imaging modality used (n = 21) and CT level of disease was the most reported imaging predictor of outcomes for pulmonary thromboendarterectomy. Although must studies evaluated hemodynamic improvements, imaging was of additional use in predicting clinically significant procedural complications after balloon pulmonary angioplasty, as well as mortality and long-term outcome after pulmonary endarterectomy. Predictors reported in MRI and digital subtraction angiography were less commonly reported and warrant multicenter validation. Cardiothoracic imaging may predict clinically significant outcomes after balloon pulmonary angioplasty and pulmonary thromboendarterectomy. Radiologists involved in the assessment of CTEPH patients should be aware of key predictors and future investigations could focus on multicenter validation and new technologies.

Patients with diabetes mellitus (DM) have chronically increased blood glucose and multiple physiologic alterations that place them at elevated risk for vascular disease. Traditionally, this vascular risk has mainly referred to chronic atherosclerosis and embolic arterial disease. Retrospective studies have suggested an increased risk of a pulmonary embolism (PE) and deep vein thrombosis (DVT), collectively termed venous thromboembolism (VTE), in patients with DM, but this association has been difficult to demonstrate with comorbidities such as obesity in meta-analysis. Clinical studies have demonstrated worse outcomes for patients with DM who suffer from VTE. In vitro studies show multiple physiologic abnormalities with chronic inflammation, endothelial dysfunction, dysfunction in the coagulation cascade, as well as other changes that drive a vicious cycle of hypercoagulability. Aggressive medical management of DM can improve vascular outcomes, and some anti-hyperglycemic therapies may modify VTE risk as well. Anticoagulation strategies are similar for patients with DM, but with some added considerations, such as high rates of comorbid renal dysfunction. More research is needed to definitively categorize DM as a risk factor for VTE and elucidate specific therapeutic strategies. [ABSTRACT FROM AUTHOR]

Venous thromboembolic disease (VTE) in burn patients is an under-diagnosed and potentially serious complication. Its incidence varies according to studies performed. This retrospective and descriptive study conducted in an intensive burn care department in Tunisia over a period of 22 months (January 1, 2021 to October 30, 2022) included 24 patients who presented a thromboembolic complication among a total of 785 admissions (incidence of 3%): pulmonary embolism in 15 cases and deep venous thrombosis (DVT) in 9 cases. The mean age of the patients was 43.8 years, with a male:female sex ratio of 2:1. Two thirds of patients (n=17) had a pathological history: hypertension (n=3); diabetes (n=2) and neoplasia (n=2). Three patients were obese. The average TBSA was 29%. Burns involved lower limbs in 19 patients (79%). The mean time to onset of VTE was 27.8 days. Acute dyspnea was present in 1/2 of cases and tachycardia in 1/3 of cases. The association hypoxia- hypocapnia was found in 5 patients. The diagnosis was confirmed by: thoracic angioscan (n=14), pulmonary scintigraphy (n=1), venous Doppler ultrasound of the lower limbs (n=2) and phleboscan of lower limbs (n=7). Factors correlated with thromboembolic risk in our study were: TBSA 20% - 39% (p=0,029; RR=4), with lower limb involvement (p=0,068), catheterization duration ≥7 days (p=0,048; RR=3) and number of catheters >1 (p=0,01; RR=3). The outcome was favorable in 13 patients and fatal in 11 patients. [ABSTRACT FROM AUTHOR]

Objectives: Upper extremity deep vein thrombosis (UEDVT) is associated with pulmonary embolism and other complications, but there are no recommendations for UEDVT prophylaxis. The purpose of this study was to establish incidence and risk factors for UEDVT and to determine efficacy of pharmacologic prophylaxis for UEDVT prevention. Methods: For this retrospective cohort study, we identified medical patients aged 18 years and older admitted to 13 Cleveland Clinic hospitals from January 2011 to December 2019. Patients with venous thromboembolism (VTE) on admission, length of stay <1 day, and who received therapeutic anticoagulation were excluded. The potential risk factors included demographics, comorbidities, and medical procedures. Comorbidities were identified via International Classification of Diseases codes, (ICD9 and ICD10), procedures from flowsheets, and prophylaxis from medications administered in the electronic medical record. DVT events were identified by a combination of International Classification of Diseases codes and confirmed by chart review. We performed multivariable logistic regression to identify independent risk factors and the association between VTE prophylaxis and UEDVT. The model's C statistic was obtained using 1000 bootstrap runs. Results: Of 194,809 patients, 496 (0.25% of cohort, 36.8% of all VTE) developed UEDVT by 14 days. In the logistic regression model (bias-corrected C statistic 0.87), 11 risk factors predicted UEDVT, the strongest being peripherally inserted central catheter (odds ratio [OR] 4.62, 95% confidence interval [CI] 3.81-5.60) and central venous catheter (OR 3.57, 95% CI 2.91-4.37). The predicted risk among individuals ranged from 0.02% to 23.4%. Prophylaxiswas negatively associated with the development of UEDVT (OR 0.72, 95% CI 0.60-0.87). Conclusions: UEDVT is rare but some patients are high risk. Therefore, UEDVTrisk factors should be added toVTE risk assessmentmodels, and patients at high risk for UEDVT should receive chemoprophylaxis. [ABSTRACT FROM AUTHOR]

Glioblastomas are among the most malignant tumors which, despite aggressive treatment, currently have an abysmal prognosis. These lesions are known to cause local and systemic perturbations in the coagulation system, leading to neoangiogenesis and a high risk of venous thromboembolism. Indeed, there have been multiple proposals of the coagulation system being a possible target for future treatment of these patients. However, nonselective anticoagulant therapy has proven suboptimal and leads to a significant increase of intracranial hemorrhage. Thus, recognizing factors that lead to hypercoagulation is considered paramount. Hyperglycemia is a well-known prothrombotic factor, a fact that has received little attention in neuro-oncology. We previously hypothesized that patients with brain tumors could be highly susceptible to iatrogenic glycemia dysregulation. Here, we analyzed the connection between glycated hemoglobin (HbA1c) and the routine coagulation markers (D-dimers, prothrombin time and activated partial thromboplastin time [aPTT]) in patients with de novo intracranial glioblastomas. Included in this study were 74 patients who were operated on in 2 hospitals: Clinical Hospital Dubrava, Zagreb, Croatia; University Hospital Center Split, Split, Croatia; and University Hospital de la Princesa, Madrid, Spain. We found a significant inverse correlation between HbA1c and aPTT (ρ = –0.379; P = 0.0009). We also found a significant inverse correlation between Ki67 immunoreactivity and aPTT (ρ = –0.211; P = 0.0082). No connection was found between HbA1c and D-dimers or prothrombin time. Our results suggest that patients with hyperglycemia, with a more proliferative glioblastoma, could in fact have their coagulation profile significantly disrupted, primarily through the intrinsic coagulation pathway. Such findings could have great clinical importance. Further research in this area could help to elucidate the vicious connection between glioblastomas and coagulation and to combat this deadly disease. [ABSTRACT FROM AUTHOR]

Given the low incidence of venous thromboembolism (VTE) in endometrial cancer patients undergoing minimally invasive surgery, coupled with the existing uncertainties within guidelines regarding pharmacologic thromboprophylaxis in this area, there is an urgent need for a comprehensive literature review. This review aims to evaluate the necessity of pharmacologic VTE prophylaxis in these patients. PubMed, Embase, Cochrane Central Register of Controlled Trials, International Clinical Trials Registry Platform, and ClinicalTrials.gov were systematically searched from inception to March 10, 2024. The analysis was performed using R version 4.2.3. Seven studies involving 3931 endometrial cancer patients were included in the analysis. Meta-analysis results revealed that within 30 days postoperatively, the incidence of VTE was 0.51% (5 out of 990) in the pharmacologic prophylaxis group and 0.70% (7 out of 995) in the mechanical prophylaxis group, with a relative risk (RR) of 1.14 (95% CI 0.19–6.95), indicating no significant difference between the groups. Additionally, within the same timeframe, the incidence of VTE was 0.37% (4 out of 1083) in the extended pharmacologic prophylaxis group and 1.14% (4 out of 352) in the non-extended pharmacologic prophylaxis group, yielding an RR of 0.41 (95% CI 0.11–1.54), again showing no significant difference between the groups. Our study indicates that routine pharmacological VTE prophylaxis may not be imperative for endometrial cancer patients undergoing minimally invasive surgery, as mechanical prophylaxis alone seems to be efficacious. However, it is crucial to acknowledge that a subset of high-risk patients may derive benefit from pharmacological prophylaxis or even extended regimens. Nonetheless, the absence of a validated risk prediction model for identifying such patients underscores the need for further research in this area. CRD 42024516595. • Mechanical VTE prophylaxis alone appears sufficient for endometrial cancer patients undergoing minimally invasive surgery. • Routine administration of pharmacological VTE prophylaxis seems unnecessary, except for patients deemed at high risk. • A risk prediction model for VTE in endometrial cancer patients undergoing minimally invasive surgery is necessary.

Patients with cervical cancer who are diagnosed with venous thromboembolism (VTE) have worse outcomes compared to those not affected. There has yet to be a reliable method to predict or prevent VTE in cervical cancer patients. Our objective is to describe the incidence of VTE in patients with recurrent and metastatic (r/mCC) and determine risk factors that may predict VTE in this setting. We performed an observational cohort study of 386 patients with r/mCC who received at least one line of systemic chemotherapy. We collected demographic, clinical, histologic data and Khorana scores for all patients. Inclusion and exclusion criteria were applied before analysis. Statistical analysis was performed using Pearson chi-square, Student's t -test, and Wilcoxon rank-sum. 232 patients were included for evaluation. Mean age was 49 years (range 20–83). The majority (167, 72%) of patients had squamous cell histology. 169 (72.8%) patients received treatment for recurrent disease and 63 (27.2%) for metastatic, stage IVB disease. 180 (78%) patients received prior radiation and 134 (58%) received bevacizumab. VTE was diagnosed in 89 (38%) patients. There were no statistically significant differences amongst clinical and pathologic characteristics between patients who developed VTE and those who did not. There was no significant association between BMI, Khorana score, radiation, bevacizumab, or immunotherapy and the development of VTE. Approximately 40% of patients with r/mCC experienced a new VTE. There were no independent risk factors that could predict VTE in this population. Due to the overwhelmingly high incidence of VTE, prophylactic anticoagulation could be strongly considered in patients with r/mCC. • Venous thromboembolisms (VTEs) are associated with increased morbidity and mortality in cervical cancer patients. • Almost 40% of patients with metastatic and recurrent cervical cancer were diagnosed with a VTE. • Current risk-stratification tools, alone and in combination with other known risk factors, could not predict VTE. • Thromboprophylaxis should be considered for patients with metastatic and recurrent cervical cancer.

With many available data sources, clinicians need to consider the benefit‐risk profile of individual anticoagulants when balancing the need for anticoagulation, including evaluating the risks in patients with comorbidities and potential drug‐drug interactions. This narrative review presents clinical data across multiple phases of drug development for the use of apixaban, a selective factor Xa inhibitor, when taken concomitantly with other agents, and evaluates the benefit‐risk profile of apixaban with these interacting medications. Key subgroup analyses from the phase 3 ARISTOTLE trial (NCT00412984) are presented using data from patients who received either concomitant inhibitors or inducers of cytochrome P450 3A4 and/or P‑glycoprotein. We also review the available evidence for the use of apixaban in patients with cancer‐associated thromboembolism, as well as the use of apixaban in patients with COVID‐19. [ABSTRACT FROM AUTHOR]
