An update on the global use of risk assessment models and thromboprophylaxis in hospitalized patients with medical illnesses from the World Thrombosis Day steering committee: Systematic review and meta-analysis.

Introduction: Venous thromboembolism (VTE) is a leading cause of cardiovascular morbidity and mortality. The majority of VTE events are hospital-associated. In 2008, the Epidemiologic International Day for the Evaluation of Patients at Risk for Venous Thromboembolism in the Acute Hospital Care Setting (ENDORSE) multinational cross-sectional study reported that only approximately 40% of medical patients at risk of VTE received adequate thromboprophylaxis.

von Willebrand factor levels in the diagnosis of von Willebrand disease: a systematic review and meta-analysis.

von Willebrand disease (VWD) is associated with significant morbidity as a result of excessive mucocutaneous bleeding. Early diagnosis and treatment are important to prevent and treat these symptoms. We systematically reviewed the accuracy of diagnostic tests using different cutoff values of von Willebrand factor antigen (VWF:Ag) and platelet-dependent von Willebrand factor (VWF) activity assays in the diagnosis of VWD.

Bleeding assessment tools in the diagnosis of VWD in adults and children: a systematic review and meta-analysis of test accuracy.

Von Willebrand disease (VWD) can be associated with significant morbidity. Patients with VWD can experience bruising, mucocutaneous bleeding, and bleeding after dental and surgical procedures. Early diagnosis and treatment are important to minimize the risk of these complications.

Menstruation, anticoagulation, and contraception: VTE and uterine bleeding.

Abnormal or excessive menstrual bleeding affects one-third of reproductive-aged women. This number increases to 70% among women on direct oral anticoagulants (DOACs). While there is some variation in frequency of heavy menstrual bleeding (HMB) with different DOAC options, all menstruating individuals should receive counseling about the risk of HMB at the time of DOAC initiation.

Global reporting of pulmonary embolism-related deaths in the World Health Organization mortality database: Vital registration data from 123 countries.

Introduction: Pulmonary embolism (PE) has not been accounted for as a cause of death contributing to cause-specific mortality in global reports.

Methods: We analyzed global PE-related mortality by focusing on the latest year available for each member state in the World Health Organization (WHO) mortality database, which provides age-sex-specific aggregated mortality data transmitted by national authorities for each underlying cause of death. PE-related deaths were defined by International Classification of Diseases, Tenth Revision codes for acute PE or nonfatal manifestations of venous thromboembolism (VTE).

ASH ISTH NHF WFH 2021 guidelines on the diagnosis of von Willebrand disease.

Background: von Willebrand disease (VWD) is the most common inherited bleeding disorder known in humans. Accurate and timely diagnosis presents numerous challenges.

Objective: These evidence-based guidelines of the American Society of Hematology (ASH), the International Society on Thrombosis and Haemostasis (ISTH), the National Hemophilia Foundation (NHF), and the World Federation of Hemophilia (WFH) are intended to support patients, clinicians, and other health care professionals in their decisions about VWD diagnosis.

HOW Collaborative position paper on the management of thrombocytopenia in pregnancy.

Thrombocytopenia in pregnancy is a common occurrence, affecting up to 10% of women by the time of birth. These recommendations aim to provide pragmatic guidance on the investigation, diagnosis and management of thrombocytopenia in pregnancy; including safety of neuraxial anaesthesia and precautions required for birth. Management of neonatal thrombocytopenia is also addressed.

Prevention and treatment of postpartum hemorrhage: focus on hematological aspects of management.

Postpartum hemorrhage (PPH) is the leading cause of global maternal mortality and accounts for approximately one-quarter of all maternal deaths worldwide. Prevention of excess maternal deaths requires a coordinated approach to prevention, early recognition, and intervention by a multidisciplinary team. Although some women have risk factors for PPH that can be identified during pregnancy or during labor or birth, most women with severe PPH do not have any risk factors.

Anticoagulation practice patterns in COVID-19: A global survey.

Background: Best practice for prevention, diagnosis, and management of venous thromboembolism (VTE) in patients with coronavirus disease 2019 (COVID-19) is unknown due to limited published data in this population.

Objectives: We aimed to assess current global practice and experience in management of COVID-19-associated coagulopathy to identify information to guide prospective and randomized studies.

Methods: Physicians were queried about their current approach to prophylaxis, diagnosis, and treatment of VTE in patients with COVID-19 using an online survey tool distributed through multiple international organizations between April 10 and 14, 2020.

How I treat lymphoma in pregnancy.

Lymphomas afflict all age groups of people, with certain types demonstrating a female predilection in adolescents and young adults. A proportion of lymphomas that are diagnosed in this population demographic occur in the setting of pregnancy. Most of these behave aggressively at presentation and require immediate or urgent therapy.

A critical review of the pathophysiology of thrombotic complications and clinical practice recommendations for thromboprophylaxis in pregnant patients with COVID-19.

Those who are infected with Severe Acute Respiratory Syndrome-related CoronaVirus-2 are theoretically at increased risk of venous thromboembolism during self-isolation if they have reduced mobility or are dehydrated. Should patients develop coronavirus disease (COVID-19) pneumonia requiring hospital admission for treatment of hypoxia, the risk for thromboembolic complications increases greatly. These thromboembolic events are the result of at least two distinct mechanisms - microvascular thrombosis in the pulmonary system (immunothrombosis) and hospital-associated venous thromboembolism.

Hemophilia gene therapy knowledge and perceptions: Results of an international survey.

Background: Hemophilia gene therapy is a rapidly evolving therapeutic approach in which a number of programs are approaching clinical development completion.
