Anticoagulation in the Management of Acute Pulmonary Embolism-A Review.

Venous thromboembolism (VTE) is a very frequent cardiovascular entity that encompasses deep vein thrombosis and pulmonary embolism (PE). This last entity represents a major cause of cardiovascular morbidity and mortality. The incidence of PE and the rate of PE-related morbidity significantly increase with age, race, and underlying medical conditions, such as malignancy.

Successful Treatment With the Oral Factor Xa Inhibitor Edoxaban in Heparin-Induced Thrombocytopenia With Thrombosis.

Heparin-induced thrombocytopenia with thrombosis (HITT) is a rare immune reaction to the drug heparin that causes increased blood clotting, putting patients at risk for arterial and venous thromboembolism which can have severe consequences. We present a case of HITT successfully treated with the direct oral anticoagulant (DOAC), edoxaban. A 56-year-old man had surgery to remove a colorectal mass.

Factor XI/XIa inhibitors for the prevention and treatment of venous and arterial thromboembolism: A narrative review.

During the past decade, direct oral anticoagulants (DOACs) have advanced and simplified the prevention and treatment of venous thromboembolism (VTE). However, there remains a high incidence of bleeds, which calls for agents that have a reduced risk of bleeding. Factor XI (FXI) deficiency is associated with lower rates of venous thrombosis and stroke compared to the general population with a lower risk of bleeding.

Complications of Right Heart Catheterization in Patients ≥70 Years of Age With Suspected Pulmonary Hypertension: Experience From a Tertiary Care Center.

Right heart catheterization (RHC) represents the gold standard diagnostic approach for pulmonary hypertension (PH). Historically, the complication rates of RHC are known to be low. The study aimed to evaluate the indications for performing RHC and the occurrence of adverse events related to the procedure in patients > over 70 years of age in a Mexican Tertiary Care Center.

Persistent Headaches in an Avid Hiker: A Case of Chronic Coccidioidal Meningitis.

The clinical presentation, diagnosis, treatment, and complications of coccidioidal meningitis caused by the dimorphic pathogenic fungus ( and ) have been well documented in the literature. Despite the abundance of literature concerning this disease manifestation, it is not very commonly seen in clinical practice, delaying its diagnosis and treatment and leading to devastating neurological sequelae. Therefore, considering this disease process as a potential diagnosis in endemic areas is important for appropriate and timely treatment.

Successful use of rivaroxaban achieving therapeutic anti-factor xa levels in a morbidly obese patient with acute intermediate-high risk pulmonary embolism.

Direct oral anticoagulants (DOACs) have become the standard of care for acute and long-term therapy for venous thromboembolism (VTE) due to their efficacy and safety profiles. The 2021 International Society on Thrombosis and Haemostasis guidelines recommend using standard DOAC dosages in patients with BMI >40 kg/m or weight >120 kg. Use of DOACs remains uncertain in morbidly obese patients with VTE, including acute PE.

A Rare Association Between Herpes Simplex Virus Type 1 and Miller-Fisher Syndrome.

The etiopathogenesis for Guillain-Barré syndrome (GBS) and Miller-Fisher syndrome (MFS), a variant of GBS, is well-documented in the literature. However, the association between MFS and an underlying herpes simplex virus type 1 (HSV-1) infection is very limited. We present a unique case of a 48-year-old man who developed diplopia, bilateral ptosis, and gait instability following an acute diarrheal illness and recurring cold sores.

Impact of Hospital-based Multidisciplinary Anticoagulation Stewardship Programs.

Antithrombotic therapies, especially anticoagulants, are high-risk medications with increased potential for adverse events. The development and implementation of a well-functioning, designated, multidisciplinary anticoagulation stewardship program (MASP), tailored to each hospital-center's needs, has the primary objectives of improving patient-centered outcomes, minimizing undesirable anticoagulation-related adverse events and minimizing hospital length of stay (LOS) and other patient-related costs. Such stewardship programs are pivotal in supporting busy clinicians with consultation on challenging clinical case scenarios, ensuring appropriate use of valuable healthcare resources, achieving compliance with anticoagulant-associated accreditation standards, and positively impacting patient-specific morbidity/mortality outcomes.

Which are the optimal thromboprophylaxis strategies for hospitalized patients with COVID-19? current controversies.

Novel coronavirus 2019 (COVID-19) represents a significant risk factor for the development of venous thromboembolism (VTE) in hospitalized with both moderate and severe/critical COVID-19. Herein, we present a brief updated review on emerging robust data on diverse thromboprophylaxis strategies used to mitigate VTE complications, as well as a personal point of view of current controversies in regards the use of therapeutic and prophylactic anticoagulation strategies, particularly in the moderately-ill subgroup of patients with COVID-19.

Pulmonary embolism response teams: Changing the paradigm in the care for acute pulmonary embolism.

Pulmonary embolism response teams (PERTs) have emerged as a multidisciplinary, multispecialty team of experts in the care of highly complex symptomatic acute pulmonary embolism (PE), with a centralized unique activation process, providing rapid multimodality assessment and risk stratification, formulating the best individualized diagnostic and therapeutic approach, streamlining the care in challenging clinical case scenarios (e.g., intermediate-high risk and high-risk PE), and facilitating the implementation of the recommended therapeutic strategies on time.

[Comment on article "Enoxaparin dose associated with decreased risk of death in COVID-19"].

In this letter to the editor, apropos of the article "Enoxaparin dose associated with decreased risk of death in COVID-19", it is discussed the role of the current thromboprophylactic strategies, as well as the potential role of heparins in the management of COVID-19.
