Introduction: The decisive key to disease-free survival in B-cell precursor acute lymphoblastic leukemia in children, is the combination of diagnostic timeliness and treatment efficacy, guided by accurate patient risk stratification. Implementation of standardized and high-precision diagnostic/prognostic systems is particularly important in the most marginalized geographic areas in Mexico, where high numbers of the pediatric population resides and the highest relapse and early death rates due to acute leukemias are recorded even in those cases diagnosed as standard risk.

Methods: By using a multidimensional and integrated analysis of the immunophenotype of leukemic cells, the immunological context and the tumor microenvironment, this study aim to capture the snapshot of acute leukemia at disease debut of a cohort of Mexican children from vulnerable regions in Puebla, Oaxaca and Tlaxcala and its potential use in risk stratification.

Diabetes mellitus (DM) is considered one of the major health diseases worldwide, one that requires immediate alternatives to allow treatments for DM to be more effective and less costly for patients and also for health-care systems. Recent approaches propose treatments for DM based on that; in addition to focusing on reducing hyperglycemia, they also consider multitargets, as in the case of plants. Among these, we find the plant known as chia to be highlighted, a crop native to Mexico and one cultivated in Mesoamerica from pre-Hispanic times.
