Desarrollo de materiales educativos para pacientes crónicos y familiares

Low literacy can difficult the use of information needed to take appropriate decisions in healthcare. This situation is associated with poorer treatment adherence, lower health outcomes and higher mortality among the population and, specifically, the elderly. It is essential that information can be understood by patients and families. This article aims to present the existing international recommendations for the design and development of educational materials and resources to chronic patients and families. This process encompasses the involvement of patients at various levels during the development process of the materials, the adaptation of the format and content to the level of understanding of the patient as well as their participation in the evaluation process. Educational materials that have been developed in collaboration with patients are more adapted to their context and promote positive changes in their health

Wnt Signaling Regulates Pulp Volume and Dentin Thickness

Odontoblasts, cementoblasts, ameloblasts and osteoblasts all form mineralized tissues in the craniofacial complex, and all these cell types exhibit active Wnt signaling during postnatal life. We set out to understand the functions of this Wnt signaling, by evaluating the phenotypes of mice in which the essential Wnt chaperone protein, Wingless was eliminated. The deletion of Wls was restricted to cells expressing Osteocalcin, which in addition to osteoblasts includes odontoblasts, cementoblasts, and ameloblasts. Dentin, cementum, enamel, and bone all formed in OCN-Cre;Wls(fl/fl) mice but their homeostasis was dramatically affected. The most notable feature was a significant increase in dentin volume and density. We attribute this gain in dentin volume to a Wnt-mediated mis-regulation of Runx2. Normally, Wnt signaling stimulates Runx2, which in turn inhibits DSP; this inhibition must be relieved for odontoblasts to differentiate. In OCN-Cre;Wls(fl/fl) mice, Wnt pathway activation is reduced and Runx2 levels decline. The Runx2-mediated repression of DSP is relieved and odontoblast differentiation is accordingly enhanced. This study demonstrates the importance of Wnt signaling in the homeostasis of mineralized tissues of the craniofacial complex
