Introduction: COVID-19 claimed millions of lives, mainly in the pre-vaccine era. Preliminary studies showed promising efficacy of convalescent plasma against SARS-CoV-2 (CP).
Objective: To evaluate the efficacy of CP in patients hospitalized for COVID-19 with moderate severity.
Background: Philadelphia negative myeloproliferative neoplasms (Ph-MPN) are clonal disorders whose pathogenesis has been elucidated in recent years, creating diagnostic and prognostic algorithms.
Aim: To study JAK2, CALR y MPL gene mutations in patients with Ph-MPN.
Materials And Methods: Descriptive cross-sectional observational study of patients with MPN (2015-2019), reviewing clinical, demographic and laboratory data.
Background: Philadelphia-negative myeloproliferative neoplasms (Ph-MPN) are chronic hematological disorders characterized by the overproduction of one or more mature myeloid blood cell lineages. Classical Ph-MPN are polycythemia vera (PV), essential thrombocytopenia (ET) and primary myelofibrosis (PMF).
Aim: To assess the epidemiological, clinical and diagnostic characteristics of Ph-MPN in Chile.
Article Synopsis
- Philadelphia-negative myeloproliferative neoplasms (Ph-MPN) are chronic blood disorders marked by excessive production of myeloid blood cells, with major types being polycythemia vera (PV), essential thrombocytopenia (ET), and primary myelofibrosis (PMF).
- A study in Chile reviewed the medical records of 462 patients referred for MPN from 2012 to 2017, finding that ET was the most common type, with a reported incidence of 1.5 cases per 100,000 people.
- Despite extensive testing for the JAK2 V617F mutation, only 30% of patients underwent a bone marrow biopsy, and overall survival was 87
The coronavirus disease 2019 (COVID19) pandemic has left researchers scrambling to identify the humoral immune correlates of protection from COVID-19. To date, the antibody mediated correlates of virus neutralization have been extensively studied. However, the extent that non-neutralizing functions contribute to anti-viral responses are ill defined.

- The study examined the clinical and survival characteristics of transplant-eligible multiple myeloma patients in Latin America, focusing on the differences between public and private healthcare systems.
- It included data from 1293 patients diagnosed from 2010 to 2018, highlighting significant disparities in outcomes and survival rates between those treated in public versus private institutions.
- The findings suggest that late diagnosis and limited access to effective treatments in public facilities contribute to poorer survival rates, while patients receiving modern therapies and autologous stem cell transplants have survival rates comparable to international standards.
Background: Hodgkin lymphoma has a high rate of curability, even in advanced stages.
Aim: To assess the results of Hodgkin lymphoma treatment using the ABVD (doxorubicin, bleomycin, vinblastine, dacarbazine) chemotherapy regimen.
Material And Methods: Analysis of a database held by the Chilean Ministry of Health, including all patients treated at accredited cancer treatment centers.
