ABSTRACT

Abstract Acute myeloid leukemia (AML) comprises a heterogeneous group of hematopoietic cell neoplasms of myeloid lineage that arise from the clonal expansion of their precursors in the bone marrow, interfering with cell differentiation, leading to a syndrome of bone marrow failure. AML is a consequence of genetic and epigenetic changes (point mutations, gene rearrangements, deletions, amplifications, and arrangements in epigenetic changes that influence gene expression) in hematopoietic precursor cells, which create a clone of abnormal cells that are capable of proliferating but cannot differentiate into mature hematopoietic cells or undergo programmed cell death. The diagnosis requires more than 20% myeloid blasts in the bone marrow and certain cytogenic abnormalities. Treatment will depend on age, comorbidities, and cytogenetic risk among the most frequent.
ABSTRACT
Entre el 1 y el 26 de junio se llevó a cabo el estudio de investigación "Encuesta de infección por coronavirus tipo 2 del síndrome respiratorio agudo grave (SARS-CoV-2), nivel comunitario en habitantes de un barrio vulnerable urbano de la ciudad de Buenos Aires", que determinó que un 54,3% de los habitantes del barrio presentaban anticuerpos inmunoglobulina tipo G para SARS-CoV-2. El objetivo de este artiÌculo es proporcionar un ejemplo de un muestreo probabilístico que fue utilizado para estimar la prevalencia de seropositividad en este estudio. (AU)
Between 1st and 26th of june, a research named "Survey of infection by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), community level in inhabitants of a marginal urban neighborhood of the city of Buenos Aires" was carried on. The study showed that 54.3% of the that 54.3% of the people of the neighborhood had antibodies immunoglobulin type G for SARS-CoV-2. The objective of this article is to provide an example of a probability sampling carried out in the study, to measuring the prevalence of seropositivity. (AU)
