bleeding risk

BACKGROUND: Low molecular weight heparin has proven to be safe and effective but is not without potential risks such as spontaneous bleeding in the abdominal cavity. There is limited evidence evaluating the true incidence of this potential risk and the available literature is primarily via case reports. CASE SUMMARY: The purpose of this study was to identify the incidence and risk factors associated with enoxaparin use (prophylaxis or treatment) abdominal hematomas in a 350-bed community hospital during an 8-month time period...

BACKGROUND: Oncological patients with coronary artery disease face an elevated risk of hemorrhagic and ischemic events following percutaneous coronary intervention. Despite medical guidelines recommending minimal dual antiplatelet therapy (DAPT) duration for patients with cancer, dedicated data on abbreviated DAPT in this population is lacking. This study aims to evaluate the occurrence of ischemic and hemorrhagic events in patients with cancer compared with other high-bleeding risk individuals...

Dual antiplatelet therapy-the combination of aspirin and a P2Y12 inhibitor-remains the standard antiplatelet regimen recommended to prevent ischemic complications immediately after percutaneous coronary intervention. Nonetheless, recent advances in stent technologies, percutaneous coronary intervention techniques, adjunctive pharmacotherapy for secondary prevention, and the rising awareness of the prognostic impact of bleeding, which are inevitably associated with dual antiplatelet therapy, led to the investigation of alternative antiplatelet regimens related to fewer bleeding and a preserved ischemic protection...

Decision analysis can play an essential role in informing practice guidelines. The American Society of Hematology (ASH) thrombophilia guidelines have made a significant step forward in demonstrating how decision modeling integrated within GRADE (Grading of Recommendations Assessment, Developing, and Evaluation) methodology can advance the field of guideline development. Although the ASH model was transparent and understandable, it does, however, suffer from the certain limitations that may have generated potentially wrong recommendations...

BACKGROUND: This systematic review and meta-analysis aimed to compare the efficacy and safety of cangrelor as compared to ticagrelor in patients with ST-elevated myocardial infarction (STEMI) who underwent percutaneous intervention. METHODS: PubMed, Embase, Scopus, Web of Science, Cochrane CENTRAL, and ClinicalTrials.gov databases were searched for relevant head-on-comparison or swapping studies. The primary outcome was the rate of high platelet reactivity (HPR) at specific time intervals after stopping cangrelor infusion during the first 24 h...

INTRODUCTION: There is uncertainty whether patients with a cerebral cavernous malformation (CCM) should undergo conservative or surgical treatment, resulting in practice variation among hospitals. Our objective was to report clinical outcomes of patients with primarily conservatively managed CCMs. PATIENTS AND METHODS: This single-center cohort study included consecutive adult CCM patients, diagnosed in 2000-2023, who underwent conservative management as primary treatment strategy...

OBJECTIVE: To determine whether adenomyosis is present in the cornual portion of hysterectomies of symptomatic sterilization device users and in patients hysterectomized for different benign causes and who presented with pelvic pain and/or menstrual alterations. METHODS: An observational, analytical, cross-sectional, single-center, retrospective cohort study was conducted in a secondary level hospital. Cohort 1 consisted of women who had Essure® hysteroscopic sterilization devices inserted between 2009 and 2017, who developed gynecologic symptoms (pelvic pain, heavy menstrual bleeding, and/or abnormal uterine bleeding) and who underwent a hysterectomy for explantation of the devices...

BACKGROUND: Previous systematic reviews have revealed an inconsistency of outcome definitions as a major barrier in providing evidence-based guidance for the use of plasma transfusion to prevent or treat bleeding. We reviewed and analyzed outcomes in randomized controlled trials (RCTs) to provide a methodology for describing and classifying outcomes. STUDY DESIGN AND METHODS: RCTs involving transfusion of plasma published after 2000 were identified from a prior review (Yang 2012) and combined with an updated systematic literature search of multiple databases (July 1, 2011 to January 17, 2023)...

BACKGROUND: Vitamin K deficiency can lead to severe coagulation dysfunction, which may be dangerous and fatal, especially in patients undergoing surgery. METHODS: We report an 84-year-old male patient with gallstones and cholecystitis who had a severe coagulation disorder without bleeding symptoms after endoscopic papillary balloon dilation for removal of bile duct stones. After vitamin K supplementation, the coagulation dysfunction was corrected the next day. RESULTS: In this case, long-term antibiotic treatment, inadequate diet, and abnormal liver function led to coagulation dysfunction...

BACKGROUND: Blood shortage is a global challenge, impacting elective surgeries with high bleeding risk. Predicting intraoperative blood use, optimizing resource allocation, and ensuring safe elective surgery are vital. This study targets identifying key bleeding risk factors in Aortic Valve Replacement (AVR) through machine learning. METHODS: Data from 702 AVR patients were split into 70% training and 30% test sets. Thirteen models predicted RBC transfusion. SHapley Additive exPlanations (SHAP) analyzed risk factors...

Tranexamic acid is safe and effective for the treatment of heavy vaginal bleeding during menstruation and childbirth. It improves the quality of life, facilitates participation in school and work, and reduces the risk of death from postpartum hemorrhage. Despite its well-established benefits, individual- and structural-level barriers preclude its widespread utilization, hindering effective patient care and perpetuating health inequities in women's health. We first describe the evidence for the use of tranexamic acid in treating heavy menstrual bleeding and postpartum hemorrhage...

BACKGROUND: The optimal perioperative antithrombotic strategy for patients with acute coronary syndrome (ACS) during percutaneous coronary intervention (PCI) remains controversial. OBJECTIVES: To determine the safety and effectiveness of bivalirudin plus ticagrelor vs bivalirudin plus clopidogrel in patients with ACS undergoing PCI in the real world. METHODS: Between March 2016 and March 2019, 7234 patients with ACS who had undergone PCI, received bivalirudin periprocedurally, and were prescribed ticagrelor or clopidogrel were enrolled in a single-center, all-comer, modern, retrospective cohort study...

We present a rare case involving a 54-year-old man with a history of pancreatitis who developed a retroperitoneal lumbar vein aneurysm that was initially misidentified as a pancreatic pseudocyst. Subsequent imaging revealed an enlarged mass and retroperitoneal perforation. Despite initial hesitation, the patient eventually underwent radical surgery that enabled the successful removal of the mass, which was near the inferior vena cava. Pathological examination confirmed varicose veins, and the final diagnosis was lumbar vein aneurysm in the retroperitoneum...

Arterial and venous thromboembolism is a major medical concern that requires therapeutic anticoagulation in various medical fields to prevent its drastic consequences. Despite significant advances in anticoagulant therapy, thrombosis remains a leading cause of morbidity and mortality worldwide. Traditional anticoagulants like heparin and vitamin K antagonists (VKAs) have shown efficacy in preventing and treating thrombosis but come with an inherent risk of bleeding due to their non-specific inhibition of multiple coagulation factors...

Oral piercing habits are associated with various degrees of complications. Tongue piercing increases the risk of gingival recession and infrabony defects, subsequently leading to localized periodontitis. In the case presented, the patient had persistent swelling and suppuration around her mandibular anterior teeth attributed to tongue piercing jewelry that was placed approximately 12 years prior. Intraoral examinations revealed a localized deep pocket, purulent discharge, swelling, plaque accumulation, bleeding on probing, gingival recession, and teeth mobility...

Major reason for mortality among systemic lupus erythematosus patients is renal failure due to the deposition of immune complexes in the glomeruli. Being a chronic disease with multiple relapses and remissions across the lifespan, it's important to know the degree of nephritis for diagnosis as well as the long-term clinical management of the patients. Currently, renal biopsy is being used as the gold standard to diagnose and define the stages of the disease. However, renal biopsy being invasive only provides a localized picture of nephritis, and has the risk of bleeding...

Antiplatelet therapy is mandatory for prevention of thrombotic events in patients with a recent history of acute coronary syndromes and/or percutaneous coronary interventions. However, if an urgent surgery is required during antiplatelet therapy, a compromise between the ischemic/thrombotic and hemorrhagic risk has to be reached. Different bridging schemes are reported in the literature, but there is no clear consensus on the optimal treatment strategy in terms of efficacy and safety. Although some indications about the perioperative management of antiplatelet therapy regarding specific surgical specializations are available, balancing the thrombotic and hemorrhagic risk on an individual basis, no evidence referring to neurosurgical or neuro-oncologic procedures is reported...

OBJECTIVES: To assess if warfarin targeted to INR 1.8 (range 1.5-2.0) is safe for all patients with an On-X aortic mechanical valve. METHODS: This prospective, observational registry follows patients receiving warfarin targeted at an INR of 1.8 (range 1.5-2.0) plus daily aspirin (75-100 mg) after On-X aortic valve replacement. The primary end-point is a composite of thromboembolism, valve thrombosis, and major bleeding. Secondary end-points include the individual rates of thromboembolism, valve thrombosis, and major bleeding, as well as the composite in subgroups of home or clinic-monitored INR and risk categorization for thromboembolism...

Dual antiplatelet therapy (DAPT) is the cornerstone of maintenance medication following acute coronary syndromes (ST elevation myocardial infarction, non-ST elevation myocardial infarction, unstable angina). Over the last decade, P2Y12 inhibition in addition to low-dose acetylsalicylic acid has been intensively debated. In patients with acute coronary syndromes, balancing the reduction in cardiovascular events and increase in major bleeding during treatment with more potent P2Y12 inhibitors such as prasugrel and ticagrelor is still an issue...

Current hospital VTE (venous thromboembolism) prophylaxis for medical patients has been characterized by both underuse and, increasingly, overuse. The American Society of Hematology (ASH) has endorsed the use of risk assessment models (RAM) as an approach to individualize VTE prophylaxis as a way of balancing overuse (excessive risk of bleeding) and underuse (risk of avoidable VTE). ASH has endorsed IMPROVE (International Medical Prevention Registry on Venous Thromboembolism) risk assessment models - the only RAM to assess short-term bleeding and VTE risk in acutely ill medical inpatients...
