RNA modifications are widespread throughout the mammalian transcriptome and play pivotal roles in regulating various cellular processes. These modifications are strongly linked to the development of many cancers. One of the most prevalent forms of RNA modifications in humans is adenosine-to-inosine (A-to-I) editing, catalyzed by the enzyme adenosine deaminase acting on RNA (ADAR) in double-stranded RNA (dsRNA).

Background: Amazonas is a region in northern Peru with the second-highest incidence of malaria. Approximately 95% of the cases are reported in the Condorcanqui province, where native communities living along the banks of Santiago River lack access to potable water, sewage, and electricity. This study aimed to analyse malaria's spatial, temporal, and climatic characteristics in Condorcanqui to guide future studies and prevention strategies.

Introduction: In Argentina, the implementation of a national strategy to reduce the prevalence of noncommunicable diseases (NCDs) has been hampered by challenges at the provincial level. We aimed to design a new model of care for NCDs at the primary care level by conducting a multimodal system assessment and co-design of potential solutions in the province of Mendoza.

Methods: We carried out a mixed-methods study with 7 components: evaluation of patterns of care, patient focus groups, cross-sectional standardized population-based phone survey, an electronic cohort follow-up of patients with type 2 diabetes, in-depth interviews with stakeholders, a knowledge test for health care providers on chronic condition management, and a Delphi consensus to provide recommendations from stakeholders.
