Application Value and Safety Analysis of Warfarin, Rivaroxaban, and Dabigatran Ester in Elderly Patients With Atrial Fibrillation.

BACKGROUND: This study aimed to evaluate the application value and safety of Warfarin, Rivaroxaban, and Dabigatran in elderly patients with atrial fibrillation. METHODS: A total of 180 elderly patients with atrial fibrillation admitted to our hospital were retrospectively analyzed. According to their anticoagulant treatment regimen, patients were divided into three groups: Warfarin (57 cases), Rivaroxaban (61 cases), and Dabigatran (62 cases). General demographic information was collected, and coagulation function indicators-including fibrinogen (FIB), thrombin time (PT), activated partial thrombin time (APTT), and D-dimer (D-D)-as well as liver function indexes-including total bilirubin (TbiL), alkaline phosphatase (ALP), aspartate aminotransferase (AST), and alanine transferase (ALT)-were compared before and after 4 weeks of treatment. RESULTS: There were no significant differences in demographic characteristics such as gender, age, body mass index, or disease course among the three groups. The total effective rate in the Warfarin group (84.21%) was significantly lower than in the Rivaroxaban (98.36%) and Dabigatran (96.77%) groups (p < 0.05). However, there was no significant difference in the total effective rate between the Rivaroxaban and Dabigatran groups (p > 0.05). Additionally, no significant differences were found in the effects of the three drugs on coagulation function, liver function, or the incidence of bleeding (p = 0.052). CONCLUSION: Warfarin, Rivaroxaban, and Dabigatran can effectively prevent thrombosis in elderly patients with atrial fibrillation, with Rivaroxaban and Dabigatran showing superior effectiveness. All three drugs demonstrated similar low rates of bleeding events and had no significant impact on coagulation and liver function.

Effects of atrial fibrillation screening according to thyroid function: Post-hoc analysis of the randomized LOOP study.

PURPOSE: Subclinical thyroid dysfunction is a marker for atrial fibrillation (AF) and stroke risk. This study explored the effects of AF screening according to thyroid-stimulating hormone (TSH) levels. METHODS: An AF screening trial (the LOOP study) was analyzed post-hoc according to baseline TSH. The primary outcome was stroke or systemic embolism (SE). Secondary outcomes included major bleeding, all-cause death, and the combination of stroke, SE, and cardiovascular death. RESULTS: TSH measurement was available in 6003 of 6004 trial participants, 1500 randomized to implantable loop recorder (ILR) screening for AF and anticoagulation upon detection vs. 4503 to usual care; mean age was 74.7±4.1 years and 2836 (47%) were women. AF detection was approximately triple for ILR vs usual care across TSH tertiles (adjusted p-interaction=0.44). In the first tertile, screening was associated with decreased risk of the primary outcome (hazard ratio 0.52 [0.30-0.90]; p=0.02) and stroke, SE, or cardiovascular death (hazard ratio 0.54 [0.34-0.84]; p=0.006) compared to usual care, while no effect was observed among participants with higher TSH (adjusted p-interaction 0.03 and 0.01, respectively). There was no effect on other outcomes. Analyses of continuous TSH or excluding those with abnormal TSH or thyroid medication showed similar results. CONCLUSION: AF screening and subsequent treatment was associated with decreased stroke risk among participants with low TSH, though the yield of screening was similar across TSH levels. TSH may be useful as a marker to indicate benefit from AF screening vs. overdiagnosis and overtreatment. These findings should be considered exploratory and warrant further study.

Current Antithrombotic Treatments for Cardiovascular Diseases: A Comprehensive Review.

Antithrombotic therapies (ATT) play a pivotal role in the management of cardiovascular diseases, aiming to prevent ischemic events while maintaining a delicate balance with the patient's bleeding risk. Typically, ATT can be classified into antiplatelet and anticoagulant therapies. Their application spans a broad spectrum of cardiovascular conditions, ranging from ischemic heart disease to atrial fibrillation, encompassing venous thromboembolisms and innovative structural interventional cardiology procedures. The global burden of cardiovascular diseases is steadily increasing, often giving rise to overlapping clinical presentations. Accordingly, the adoption of combined pharmacological approaches becomes imperative, potentially disrupting the delicate equilibrium between ischemic and bleeding risk, thus leading to nuanced pharmacotherapeutic pathways. In this context, contemporary investigations strive to identify a convergence point that optimizes the duration of medical therapy while addressing the need for antithrombotic effects, especially in the context of ischemic heart disease. This review aims to comprehensively revisit the main antithrombotic strategies in cardiovascular diseases, with the intention of enhancing a systematic approach which is key for the effective clinical management of these patients. Also, the review will examine the most impactful studies that have established the groundwork for current scientific evidence, with acknowledgement of special populations. Finally, we will cast a gaze into the future of this dynamic and evolving research field, exploring forthcoming perspectives and advancements.

Atrial High-Rate Episodes and Subclinical Atrial Fibrillation: State of the Art and Clinical Questions with Complex Solutions.

Atrial high-rate episodes (AHREs) and subclinical atrial fibrillation (AF) are frequently registered in asymptomatic patients with cardiac implantable electronic devices (CIEDs) and insertable cardiac monitors (ICMs). While an increased risk of thromboembolic events (e.g., stroke) and benefits from anticoagulation have been widely assessed in the setting of clinical AF, concerns persist about optimal clinical management of subclinical AF/AHREs. As a matter of fact, an optimal threshold of subclinical episodes' duration to predict stroke risk is still lacking and recently published randomized clinical trials assessing the impact of anticoagulation on thromboembolic events in this specific setting have shown contrasting results. The aim of this review is to summarize current evidence regarding classification and clinical impact of subclinical AF/AHREs and to discuss the latest evidence regarding the potential benefit of anticoagulation in this setting, highlighting which clinical questions are still unanswered.

Elderly Patients with Venous Thromboembolism: Insights from the RIETE Registry.

Venous thromboembolism (VTE) presents a notable healthcare burden, particularly among the elderly, who experience increased risks and more severe complications. This review aims to use the extensive data from the RIETE registry, a comprehensive database on consecutive patients with VTE. We examine the clinical features, therapeutic approaches, and patient outcomes of VTE in elderly patients, compared to younger patients, offering a comprehensive understanding of management challenges and emphasizing the need for strategies that accommodate the unique challenges of this population.

Atrial Fibrillation in Hypertrophic Cardiomyopathy.

Atrial fibrillation (AF) is common among patients with hypertrophic cardiomyopathy (HCM) with a prevalence greater than 25%. AF in HCM is associated with a high risk of stroke and can be a marker of more advanced cardiomyopathy. Although, it frequently results in cardiac hemodynamic changes which are poorly tolerated, it can be subclinical. Thus, prompt diagnosis and adequate management of AF are essential to minimizing AF-related adverse outcomes in HCM. All HCM patients should be screened for AF regularly, and those with high-risk features should be screened more frequently preferably with extended ambulatory monitoring. Once AF is detected, oral anticoagulation should be initiated. Both general and HCM-specific modifiable risk factors should be addressed and assessment for cardiomyopathy progression should be performed. Although no randomized controlled studies have compared rate versus rhythm control in HCM, early rhythm control could be considered to prevent further LA remodeling.

Management of perioperative anticoagulation in patients with mechanical heart valve replacement undergoing laparoscopic cholecystectomy: a case report of postoperative cerebral embolism.

Patients with mechanical heart valve replacement require lifelong anticoagulation therapy, and additional surgeries can pose a risk of bleeding and thromboembolic events due to the need for perioperative anticoagulation management. Here, we present a case report of a patient who underwent laparoscopic cholecystectomy (LC) and endoscopic retrograde cholangiopancreatography (ERCP) after mechanical heart valve replacement and experienced postoperative cerebral embolism. The management of perioperative anticoagulation in these patients is discussed, including strategies for minimizing the risks of bleeding and thromboembolic events during and after surgery.

Exploring the use of electroconvulsive therapy in the anticoagulated population: A systematic review.

BACKGROUND: Electroconvulsive therapy is an effective treatment for several psychiatric conditions. There are theoretical risks associated with electroconvulsive therapy in patients who are anticoagulated. However, there is no review investigating these adverse effects. AIM: This systematic review explored the literature on using electroconvulsive therapy in anticoagulated patients, including adverse effects associated with continuation or cessation of anticoagulation during electroconvulsive therapy. METHODS: The study was registered on PROSPERO (registration CRD42023432178). A search was conducted across CENTRAL, Embase, Medline and PsychINFO databases, with title and abstract screening, full-text review and data extraction by two independent reviewers. Patients planned for electroconvulsive therapy and on anticoagulation prior to electroconvulsive therapy were included. Papers not related to electroconvulsive therapy or anticoagulation were excluded. Data were recorded in Microsoft Excel, presented in tables. RESULTS: The studies comprised 108 patients and over 700 sessions of electroconvulsive therapy. 64.81% patients were on warfarin, 22.22% on a direct-acting oral anticoagulant, 5.55% on heparin and the rest on enoxaparin, dalteparin, acenocoumarol or bemiparin. There were two reports of both nonfatal non-central nervous system bleeding and pulmonary embolism in patients with anticoagulation. There were no intracranial haemorrhages or deaths. Bridging or substitution with an anticoagulant with a shorter half-life had no additional benefit. CONCLUSION: This review showed tolerability of anticoagulants continued throughout electroconvulsive therapy, with most patients reporting no adverse effects. Given limitations including few studies and medical comorbidities influencing patient risk profile, further studies are required to guide practice recommendations and review long-term outcomes.

Anticoagulation in embolic acute limb ischaemia-an observational study.

The management of embolic acute limb ischaemia commonly involves determining aetiology and performing emergency invasive procedures. This detailed study aimed to determine the impact of manipulation of anticoagulation in the aetiology of emboli in acute limb ischaemia and determine the efficacy of primary anticoagulation therapy vs. invasive interventions. Material and methods: Data collection was conducted at a single institution on a cohort of patients presenting consecutively with embolic acute limb ischaemia over one year. Two groups were compared, one receiving anticoagulation as primary therapy with those undergoing invasive treatment as the internal comparison group. Results: A likely haematological causation was identified in 22 of 38 presentations, related to interruption of anticoagulation in cardiac conditions, the majority atrial fibrillation (n=12), or hypercoagulable states (n=10). Limb salvage was pursued in 36 patients employing anticoagulation (n=19) or surgical embolectomy (n=17) as the primary therapy in upper and lower limbs (n=17 vs n=19 respectively). Despite delays often well beyond six hours and a range of ischaemic severity in both groups, 35 of 36 patients achieved full or substantive restoration of function with improved perfusion. Regarding anatomical distribution of arterial disease and therapy, three patients with multi-level disease proceeded to embolectomy following anticoagulation. Embolectomy was undertaken most often for proximal emboli and more profound paralysis. Conclusions: Anticoagulation and coagulopathy are commonly implicated in the aetiology of arterial emboli, with omission of effective anticoagulation in atrial fibrillation being associated in almost 1/3 of presentations. Whilst more profound limb paralysis and proximal or multi-level disease tended to be managed surgically, primary anticoagulation therapy alone or with a secondary embolectomy was effective across the spectrum of ischaemia severity and despite significant delays beyond guideline recommendations.

Exploring stakeholder perceptions of implementing a pharmacist-led anticoagulation clinic in primary care settings: a cross-sectional study.

Background: Anticoagulation therapy is crucial for managing various cardiovascular and thrombotic conditions; however, optimal delivery remains challenging in primary care. Pharmacist-led anticoagulation services have emerged as a potential strategy for enhancing patient care and outcomes in such settings. Understanding the perspectives of key stakeholders is critical for successful implementation. Objectives: This study aimed to explore the perceptions of key stakeholders involved in the implementation of pharmacist-led anticoagulation clinics in primary care settings. Methods: A cross-sectional study was conducted using structured, pilot-tested questionnaires between August and October 2023. Patients receiving warfarin, pharmacists, and physicians working across various primary healthcare centres were invited to complete an online survey. Each group of stakeholders had individualised questionnaires to assess their perceptions and expectations with regard to developing pharmacist-led anticoagulation clinics in primary care. Descriptive statistics were used to analyze the data. Results: The response rates for the survey were 29.4% for physicians, 10.4% for patients, and 48.6% for pharmacists. Participants expressed positive perceptions toward pharmacist-led anticoagulation clinics, acknowledging benefits such as improved access to care, enhanced medication management, and increased patient education. The respondents expressed confidence in the expertise and skills of pharmacists in this role. However, healthcare providers strongly agree that pharmacists should receive additional training specific to anticoagulation management. Establishing standardised protocols and fostering interprofessional collaboration were identified as the main facilitators for practical implementation. Conclusions: Broad support exists for pharmacist-led anticoagulation clinics in primary care, though additional pharmacist training and accountability concerns need to be addressed for successful implementation.

Apixaban, edoxaban and rivaroxaban but not dabigatran are associated with higher mortality compared to vitamin-K antagonists: A retrospective German claims data analysis.

BACKGROUND: Vitamin-K antagonists (VKAs) have widely been replaced by non-VKA oral anticoagulants (NOACs). This includes Austria, Germany and Switzerland, where as VKA, instead of warfarin, the much longer-acting phenprocoumon is used, which was not compared to NOACs in clinical trials. METHODS: Using administrative data from a large German health insurance, we included all anticoagulation-naïve patients with a first prescription of a NOAC or VKA between 2012 and 2020. We analysed overall survival, major adverse cardiac and cerebrovascular events, major thromboembolic events and major bleeding. RESULTS: Overall, 570,137 patients were included (apixaban: 26.9%, dabigatran: 4.6%, edoxaban: 8.8%, rivaroxaban: 39.1% and VKA: 20.7% of these 99.4% phenprocoumon). In the primary analysis using a 1:1 propensity score matching-cohort (PSM-cohort), a significantly higher overall mortality was found for apixaban, edoxaban and rivaroxaban (all p < 0.001) but not for dabigatran (p = 0.13) compared to VKA. In this PSM-cohort, 5-year mortality was 22.7% for apixaban versus 12.7% for VKA, 19.5% for edoxaban versus 11.4% for VKA, 16.0% for rivaroxaban versus 12.3% for VKA (all p < 0.001) and 13.0% for dabigatran versus 12.8% for VKA (p = 0.06). The observed effect was confirmed in sensitivity analyses using un-weighted and three different weighted Fine-Gray regression models on the basis of the entire cohort. CONCLUSIONS: In this large real-world analysis, apixaban, edoxaban and rivaroxaban, but not dabigatran, were associated with worse survival compared to VKA. These findings, consistent with a few other studies including phenprocoumon, cast profound doubts on the unreflected, general use of NOACs. Randomized trials should assess whether phenprocoumon might actually be superior to NOACs.

Anticoagulation in device-detected atrial fibrillation with or without vascular disease: a combined analysis of the NOAH-AFNET 6 and ARTESiA trials.

BACKGROUND AND AIMS: The optimal antithrombotic therapy in patients with device-detected atrial fibrillation (DDAF) is unknown. Concomitant vascular disease can modify the benefits and risks of anticoagulation. METHODS: These pre-specified analyses of the NOAH-AFNET 6 (n=2534 patients) and ARTESiA (n=4012 patients) trials compared anticoagulation to no anticoagulation in patients with DDAF with or without vascular disease, defined as prior stroke/transient ischemic attack, coronary or peripheral artery disease. Efficacy outcomes were the primary outcomes of both trials, a composite of stroke, systemic arterial embolism (SE), myocardial infarction, pulmonary embolism or cardiovascular death, and stroke or SE. Safety outcomes were major bleeding or major bleeding and death. RESULTS: In patients with vascular disease (NOAH-AFNET 6 56%, ARTESiA 46.0%), stroke, myocardial infarction, systemic or pulmonary embolism, or cardiovascular death occurred at 3.9%/patient-year with and 5.0%/patient-year without anticoagulation (NOAH-AFNET 6), and 3.2%/patient-year with and 4.4%/patient-year without anticoagulation (ARTESiA). Without vascular disease, outcomes were equal with and without anticoagulation (NOAH-AFNET 6 2.7%/patient-year, ARTESiA 2.3%/patient-year in both randomised groups). Meta-analysis found consistent results across both trials (I2heterogeneity=6%) with a trend for interaction with randomised therapy (pinteraction=0.08). Stroke/SE behaved similarly. Anticoagulation increased major bleeding in vascular disease patients (edoxaban 2.1%/patient-year, no anticoagulation 1.3%/patient-year; apixaban 1.7%/patient-year; no anticoagulation 1.1%/patient-year; incidence rate ratio 1.55 [1.10-2.20]) and without vascular disease (edoxaban 2.2%/patient-year; no anticoagulation 0.6%/patient-year; apixaban 1.4%/patient-year; no anticoagulation 1.1%/patient-year, incidence rate ratio 1.93 [0.72-5.20]). CONCLUSIONS: Patients with DDAF and vascular disease are at higher risk of stroke and cardiovascular events and may derive a greater benefit from anticoagulation than patients with DDAF without vascular disease.

The anticoagulation one year after ablation of atrial fibrillation in patients with atrial fibrillation (ALONE-AF) trial: Study protocol.

Background: The ideal long-term antithrombotic strategy for patients after successful catheter-based atrial fibrillation (AF) ablation is still uncertain. Presently, practices vary, and the advantages of oral anticoagulation (OAC) for the post-ablation population are not clearly established. To date, no randomized trials have addressed this therapeutic question. This study aimed to evaluate whether no OAC therapy is superior to apixaban in reducing the risk of stroke, systemic embolism, or major bleeding among patients without apparent recurrent atrial arrhythmias for at least 1 year after their AF ablation procedure. Methods: The ALONE-AF trial is a prospective, multicenter, open-label, randomized study with blinded outcome assessment. Patients with AF who have at least one non-gender stroke risk factor (as determined by the CHA2DS2-VASc score) and no documented recurrences of atrial arrhythmia for at least 12 months post-ablation will be randomly assigned to apixaban 5 mg b.i.d. or no OAC therapy. The primary endpoint is a composite outcome of stroke, systemic embolism, and major bleeding. Key secondary outcomes include clinically relevant non-major bleeding, all-cause mortality, myocardial infarction, transient ischemic attack, quality of life, and frailty analysis. Participants will be followed for a period of 2 years. The estimated total sample size is 840 subjects, with 420 subjects in each arm. Conclusion: The ALONE-AF trial aims to provide robust evidence for the optimal anticoagulation strategy for patients with stroke risk factors following successful AF ablation.

Actioning atrial fibrillation identified by ambulance services in England: a qualitative exploration.

OBJECTIVES: To explore the acceptability and feasibility of detection of atrial fibrillation (AF) by emergency medical services (EMS) and identify potential barriers and facilitators to implementing a formal pathway to facilitate follow-up in primary care, which could reduce the risk of AF-related stroke. DESIGN: Qualitative study using focus groups and one-to-one interviews guided by a semistructured topic guide. SETTING: North East England. PARTICIPANTS: Focus groups with 18 members of the public and one-to-one online interviews with 11 healthcare and service providers (six paramedics and five experts representing cardiology, general practice (GP), public health, research, policy and commissioning). RESULTS: All participant groups were supportive of a role of EMS in identifying AF as part of routine assessment and formalising the response to AF detection. However, this should not create delays for EMS since rate-controlled AF is non-urgent and alternative community mechanisms exist to manage it. Public participants were concerned about communication of the AF diagnosis and whether this should be 'on scene' or in a subsequent GP appointment. Paramedics reported frequent incidental identification of AF, but it is not always clear 'on scene' that this is a new diagnosis, and there is variation in practice regarding whether (and how) this is communicated to the GP. Paramedics also focused on ensuring the safety of non-conveyed patients and a perceived need for an 'active' reporting process, so that a finding of AF was actioned. Field experts felt that a formal pathway would be useful and favoured a simple intervention without adding to time pressures unnecessarily. CONCLUSIONS: There is support for the development of a formal pathway to ensure follow-up for people with AF that is incidentally detected by EMS. This has the potential to improve anticoagulation rates and reduce the risk of stroke.

Automated regional citrate anticoagulation system based on individualized dosing models in nonliver failure patients undergoing PIRRT therapy.

INTRODUCTION: Regional citrate anticoagulation is a preferred option for renal replacement therapy in critically ill patients. However, current implementations ignore individual differences that may exist in the fluctuation of patients' ionized calcium levels. To address this problem, individualized citrate and calcium supplementation models were established based on the pharmacokinetic and clearance characteristics of citrate, and an automated regional citrate anticoagulation system was built with these models as its core to facilitate the treatment of clinical patients. This study was designed to preliminarily evaluate the safety and efficacy of this system, the SuperbMed® RCA-SP100 automated regional citrate anticoagulation system, in prolonged intermittent renal replacement therapy. METHODS: Seven patients undergoing prolonged intermittent renal replacement therapy completed treatment with the SuperbMed® RCA-SP100 system. In vivo and in vitro ionized calcium levels were measured every hour before and after the start of dialysis. The accuracy and alarm sensitivity of the pumps were also monitored. RESULTS: During seven treatments, the average extracorporeal ionized calcium level was 0.34 ± 0.02 mmol/L, and the mean ionized calcium level in vivo was 1.09 ± 0.07 mmol/L. No patient required intervention, and there was no filter coagulation. The pumps all had an absolute accuracy less than 5%, and alarms could be triggered precisely. CONCLUSIONS: We reported on an automated system that allows for individualized citrate and calcium supplementation in prolonged intermittent renal replacement therapy and enables the precise and secure implementation of regional citrate anticoagulation.

Catheter and Non-Catheter-Related Venous Thromboembolism in Cancer Patients: Survival, Anticoagulation Efficacy, and Safety.

PURPOSE: To investigate the differences in survival after venous thromboembolism (VTE) and anticoagulation efficacy and safety between catheter (CRVTE) and non-catheter-related VTE (NCRVTE) in cancer patients. METHODS: A retrospective research was conducted, and consecutive cancer (digestive, respiratory, genitourinary, blood and lymphatic, and the other cancers) patients with VTE were enrolled. The anticoagulation therapies included low-molecular-weight heparin (LMWH), warfarin, new type of direct oral anticoagulants (NDOACs), LMWH combined with warfarin, and LMWH combined with NDOACs. Data were collected from the electronic medical record database of our hospital and were analyzed accordingly by Kruskal-Wallis H Test, Chi-square test, Fisher's exact test, Logistic regressions, Kaplan-Meier analysis, and Cox regressions. RESULTS: 263 patients were included, median age in years (interquartile range) was 64(56-71) and 60.5% were male. VTE recurrence rate was 16.7% in CRVTE group which was significantly lower than 34.8% in NCRVTE group (P = .032). Heart diseases were independently associated with VTE recurrence (P = .025). Kaplan-Meier survival estimates at 1, 2, and 3 years for CRVTE group were 62.5%, 60.0%, and 47.5%, respectively, compared with 47.9% (P = .130), 38.7% (P = .028), and 30.1% (P = .046), respectively, for NCRVTE group. Cox regression showed surgery (P = .003), anticoagulation therapy types (P = .009), VTE types (P = .006) and cancer types (P = .039) were independent prognostic factors for 3-year survival after VTE. Nonmajor and major bleeding were not significantly different (P = .417). Anticoagulation therapy types were independently associated with the bleeding events (P = .030). CONCLUSIONS: Cancer patients with CRVTE potentially have a better anticoagulation efficacy and survival compared to NCRVTE, and the anticoagulation safety seems no significant difference.

Assessing ChatGPT4 with and without retrieval-augmented generation in anticoagulation management for gastrointestinal procedures.

Background: In view of the growing complexity of managing anticoagulation for patients undergoing gastrointestinal (GI) procedures, this study evaluated ChatGPT-4's ability to provide accurate medical guidance, comparing it with its prior artificial intelligence (AI) models (ChatGPT-3.5) and the retrieval-augmented generation (RAG)-supported model (ChatGPT4-RAG). Methods: Thirty-six anticoagulation-related questions, based on professional guidelines, were answered by ChatGPT-4. Nine gastroenterologists assessed these responses for accuracy and relevance. ChatGPT-4's performance was also compared to that of ChatGPT-3.5 and ChatGPT4-RAG. Additionally, a survey was conducted to understand gastroenterologists' perceptions of ChatGPT-4. Results: ChatGPT-4's responses showed significantly better accuracy and coherence compared to ChatGPT-3.5, with 30.5% of responses fully accurate and 47.2% generally accurate. ChatGPT4-RAG demonstrated a higher ability to integrate current information, achieving 75% full accuracy. Notably, for diagnostic and therapeutic esophagogastroduodenoscopy, 51.8% of responses were fully accurate; for endoscopic retrograde cholangiopancreatography with and without stent placement, 42.8% were fully accurate; and for diagnostic and therapeutic colonoscopy, 50% were fully accurate. Conclusions: ChatGPT4-RAG significantly advances anticoagulation management in endoscopic procedures, offering reliable and precise medical guidance. However, medicolegal considerations mean that a 75% full accuracy rate remains inadequate for independent clinical decision-making. AI may be more appropriately utilized to support and confirm clinicians' decisions, rather than replace them. Further evaluation is essential to maintain patient confidentiality and the integrity of the physician-patient relationship.

Lung carcinoma with adrenal metastasis and inferior vena cava thrombosis in an elderly patient with decompensated chronic liver disease: a case report.

Introduction: Managing patients with complex comorbidities poses significant diagnostic and therapeutic challenges. This case report details a 65-year-old male with a history of decompensated chronic liver disease (CLD) and portal hypertension, who presented with symptoms suggestive of liver disease exacerbation. He was later diagnosed with primary lung malignancy and extensive thrombosis, including the inferior vena cava (IVC) and heart chambers, a rare finding. Case presentation: A 65-year-old man with a history of smoking, alcohol consumption, and chronic liver disease presented with severe pain in the upper right quadrant, dyspnea, weakness, loss of appetite, and unintentional weight loss. Medical assessments revealed decompensated CLD with elevated bilirubin levels, low albumin, and an elevated INR. Imaging showed lung cancer with metastasis to the adrenal gland and a large IVC thrombus extending to the heart chambers. The patient decided to pursue palliative care. Discussion: When dealing with primary lung cancer and adrenal metastasis, it's important to thoroughly assess atypical presentations for IVC thrombus. Even with advances in imaging and treatments, managing IVC thrombus related to cancer is still difficult and requires a team approach. This case highlights underdiagnosis in areas with limited resources, emphasizing the need for timely advanced diagnostics such as CT and MR imaging. Conclusion: This case highlights the complexities of diagnosing and managing patients with multiple conditions. It emphasizes the need for patient-centered care and the importance of ongoing research to develop effective diagnostic and treatment strategies for conditions like IVC thrombus in the context of malignancy.

Rescue therapy of early neurological deterioration in lacunar stroke.

BACKGROUND: Early neurological deterioration (END) occurs in many patients with acute ischemic stroke due to a variety of causes. Although pharmacologically induced hypertension (PIH) and anticoagulants have been investigated in several clinical trials for the treatment of END, the efficacy and safety of these treatments remain unclear. Here, we investigated whether PIH or anticoagulation is better as a rescue therapy for the progression of END in patients with lacunar stroke. METHODS: This study included patients with lacunar stroke who received rescue therapy with END within 3 days of symptom onset between April 2014 and August 2021. In the PIH group, phenylephrine was administered intravenously for 24 h and slowly tapered when symptoms improved or after 5 days of PIH. In the anticoagulation group, argatroban was administered continuously intravenously for 2 days and twice daily for next 5 days. We compared END recovery, defined as improvement in NIHSS from baseline, excellent outcomes (0 or 1 mRS at 3 months), and safety profile. RESULTS: Among the 4818 patients with the lacunar stroke, END occurred in 147 patients. Seventy-nine patients with END received PIH (46.9%) and 68 patients (46.3%) received anticoagulation therapy. There was no significant difference in age (P = 0.82) and sex (P = 0.87) between the two groups. Compared to the anticoagulation group, the PIH group had a higher incidence of END recovery (77.2% vs. 51.5%, P < 0.01) and excellent outcomes (34.2% vs. 16.2%, P = 0.04). PIH was associated with END (HR 2.49; 95% CI 1.06-5.81, P = 0.04). PIH remained associated with END recovery (adjusted HR 3.91; 95% CI 1.19-12.90, P = 0.02). Safety outcomes, like hemorrhagic conversion and mortality, were not significantly different between the two groups. CONCLUSIONS: As a rescue therapy for the progression of END in lacunar stroke patients, PIH with phenylephrine was more effective with similar safety compared to anticoagulation with argatroban.

Pharmacist Use of a Population Management Dashboard for Safe Anticoagulant Prescribing: Evaluation of a Nationwide Implementation Effort.

BACKGROUND: Direct oral anticoagulants (DOACs) have complex dosing regimens and are often incorrectly prescribed. We evaluated a nationwide DOAC population management dashboard rollout whose purpose includes pharmacist review and correction of off-label dosing prescriptions. METHODS AND RESULTS: Using data from Veterans Health Affairs, we identified all patients prescribed DOACs for atrial fibrillation or venous thromboembolism between August 2015 and December 2019. Sites were grouped on the basis of the timing of moderate-high usage of the DOAC population management tool dashboard. Effectiveness was defined as the monthly rate of off-label DOAC prescribing and the rate of clinical adverse events (bleeding, composite of stroke or venous thromboembolism). Implementation was evaluated as the percentage of off-label DOAC prescriptions changed within 7 days. Among the 128 652 patients receiving DOAC therapy at 123 centers, between 6.9% and 8.6% had off-label DOAC prescriptions. Adoption of the DOAC population management tool dashboard before July 2018 was associated with a decline in off-label dosing prescriptions (8.7%-7.6%). Only 1 group demonstrated a significant reduction in monthly rates of bleeding following implementation. All sites experienced a reduction in the composite of venous thromboembolism or stroke following dashboard adoption. There was no difference in the implementation outcome of DOAC prescription change within 7 days in any of the adoption groups. CONCLUSIONS: Early adoption of the DOAC population management tool dashboard was associated with decreased rates of off-label DOAC dosing prescription and reduced bleeding. Following adoption of the DOAC population management tool dashboard, all sites experienced reductions in venous thromboembolism and stroke events.
