Venous Thromboembolism Risk and Adherence to Pharmacological Thromboprophylaxis in Hospitalized Patients in Uruguay: First Nationwide Study.

Introduction: Venous thromboembolism (VTE) is a serious, frequent, and preventable medical complication in hospitalized patients. Although the efficacy of prophylaxis (pharmacological and/or mechanical) has been demonstrated, compliance with prophylaxis is poor at international and national levels.

Aim: To determine the indication and use of pharmacological thromboprophylaxis in hospitalized patients in Uruguay.

Endothelium-biomarkers for postthrombotic syndrome: a case-control study.

Background: The postthrombotic syndrome (PTS) is a long-term complication of deep venous thrombosis (DVT). Increase knowledge on the PTS pathophysiology and novel biomarkers are needed in order to predict PTS development and to improve treatment results. The aim of this study was to analyze novel endothelium-biomarkers for PTS in patients with DVT out of the acute phase.

TGF-β/SMAD Pathway Is Modulated by miR-26b-5p: Another Piece in the Puzzle of Chronic Lymphocytic Leukemia Progression.

Clinical and molecular heterogeneity are hallmarks of chronic lymphocytic leukemia (CLL), a neoplasm characterized by accumulation of mature and clonal long-lived CD5 + B-lymphocytes. Mutational status of the IgHV gene of leukemic clones is a powerful prognostic tool in CLL, and it is well established that unmutated CLLs (U-CLLs) have worse evolution than mutated cases. Nevertheless, progression and treatment requirement of patients can evolve independently from the mutational status.

[Compliance with post-cesarean section thromboprophylaxis recommendations. A cross sectional study in 233 women].

Background: Cesarean section increases four times the risk of venous thromboembolism compared to vaginal delivery. The Royal College of Obstetricians and Gynecologists guidelines are used at our service. A written alert was designed to stratify patients at high, intermediate or low risk making a suggestion for thromboprophylaxis.

Germline CEBPA mutation in familial acute myeloid leukemia.

Myeloid Neoplasms with germline predisposition become part of 2016 World Health Organization (WHO) classification of hematological malignancies since 2016. CCAAT/enhancer binding protein-alpha () is a myeloid transcription factor located in chromosome 19q. Acute myeloid leukemia (AML) with biallelic mutations of CEBPA AML with recurrent genetic abnormalities according to WHO classification.

Spinal cord compression due to a solitary, bulky plasmacytoma of posterior mediastinum.

Solitary plasmacytoma is a rare clonal plasma cell tumor, representing 2-5% of plasma cell disorders. The standard treatment is local radiotherapy. However, in some cases, its use is limited by the size and/or location of the mass.

2021 Update of the International Council for Standardization in Haematology Recommendations for Laboratory Measurement of Direct Oral Anticoagulants.

In 2018, the International Council for Standardization in Haematology (ICSH) published a consensus document providing guidance for laboratories on measuring direct oral anticoagulants (DOACs). Since that publication, several significant changes related to DOACs have occurred, including the approval of a new DOAC by the Food and Drug Administration, betrixaban, and a specific DOAC reversal agent intended for use when the reversal of anticoagulation with apixaban or rivaroxaban is needed due to life-threatening or uncontrolled bleeding, andexanet alfa. In addition, this ICSH Working Party recognized areas where additional information was warranted, including patient population considerations and updates in point-of-care testing.

[Iron deficiency in reproductive age university women at the School of Medicine, Uruguay].

Introduction: Disorders of iron metabolism are very common pathological conditions. Iron deficiency, with or without anemia, is estimated to affect more than 2 billion people.The aim of this study was to determine the prevalence of iron deficiency and anemia and their predisposing factors in a group of premenopausal women, university students of the School of Medicine of the University of the Republic in Uruguay.

5-Azacytidine restores interleukin 6-increased production in mesenchymal stromal cells from myelodysplastic patients.

Introduction: Myelodysplastic syndromes (MDS) are a heterogeneous group of clonal hematological diseases. In addition to defects in hematologic progenitor and stem cells, dysfunctions in the bone marrow microenvironment (BMM) participate in the MDS pathogenesis. Furthermore, the immune response is deregulated by the pro-inflammatory response prevailing in low-risk MDS, while immunosuppression predominates in high-risk MDS.

LPL protein in Chronic Lymphocytic Leukaemia have different origins in Mutated and Unmutated patients. Advances for a new prognostic marker in CLL.

Lipoprotein lipase (LPL) mRNA expression in chronic lymphocytic leukaemia (CLL) is associated with an unmutated immunoglobulin profile and poor clinical outcome. We evaluated the subcellular localization of LPL protein in CLL cells that did or did not express LPL mRNA. Our results show that LPL protein is differently located in CLL cells depending on whether it is incorporated from the extracellular medium in mutated CLL or generated de novo by leukaemic cells of unmutated patients.

International Council for Standardization in Haematology (ICSH) Recommendations for Laboratory Measurement of Direct Oral Anticoagulants.

This guidance document was prepared on behalf of the International Council for Standardization in Haematology (ICSH) for providing haemostasis-related guidance documents for clinical laboratories. This inaugural coagulation ICSH document was developed by an ad hoc committee, comprised of international clinical and laboratory direct acting oral anticoagulant (DOAC) experts. The committee developed consensus recommendations for laboratory measurement of DOACs (dabigatran, rivaroxaban, apixaban and edoxaban), which would be germane for laboratories assessing DOAC anticoagulation.

Compliance with the 2009 Royal College of Obstetricians and Gynaecologists guidelines for venous thromboembolic disease prophylaxis in pregnancy and postpartum period in Uruguay.

: Venous thromboembolism remains as one of the leading causes of maternal death. Prevention of venous thromboembolism in the obstetric population is challenging as recommendations for prophylaxis have low grade of evidence. Risk factors and prophylaxis guidelines have been highlighted by Royal College of Obstetricians and Gynaecologists.

Results of high-risk neutropenia therapy of hematology-oncology patients in a university hospital in Uruguay.

Background: Febrile neutropenia is an important cause of mortality and morbidity in hematology-oncology patients undergoing chemotherapy. The management of febrile neutropenia is typically algorithm-driven. The aim of this study was to assess the results of a standardized protocol for the treatment of febrile neutropenia.

[Comparison between CHOP-like and R-CHOP in diffuse large B cell and follicular lymphoma].

Background: The most common types of non-Hodgkin lymphoma (NHL) are diffuse large B cell (DLBCL) and follicular (FL).

Aim: To analyze the benefit of Rituxi-mab in overall survival (OS) of patients with NHL.

Material And Methods: Review of medical record of 230 adult patients with a first episode of NHL admitted between 2002 and 2011.

[Cytarabine and skin reactions in acute myeloid leukemia].

Cytarabine is an antimetabolite used in the treatment of acute myeloid leukemia (AML). It has many adverse effects as: myelosuppression, toxic reactions involving central nervous system, liver, gastrointestinal tract, eyes or skin. Dermatologic toxicity is often described as rare; nevertheless there are differences in the reported frequency.
