Què saben els pares dels infants de 0-3 anys, sobre l'ús del rentat nasal i els inhaladors amb cambra?

Aquest estudi insisteix en la importància de l’educació sanitària dirigida als pares per tald’assegurar l’eficàcia del tractament a administrar i consolidar els coneixements i habilitats del progenitors per tal de que aquests puguin dur a terme les tècniques requerides de forma adequada.Destacar la necessitat de conscienciar a tots els professionals de la salut, sobretot els quepassen més temps amb els familiars, de la importància que té la seva competència comeducador en l’àmbit de la salut.Evidenciar la importància de fer una avaluació continuada dels coneixements i les habilitatsadquirides pels cuidadors principals, sobre com dur a terme les tècniques del rentat de nas iadministració de la medicació inhalada amb cambra i mascareta, per detectar-ne els possibleserrors i poder posar-hi mesures correctores per pal·liar-los.Constatar la utilitat de preguntar i esbrinar “in situ” què saben els progenitors sobre lestècniques a avaluar (rentat de nas i administració de la medicació inhalada amb cambra i mascareta), abans de donar qualsevol explicació o iniciar l’educació sanitària per detectar lesnecessitats específiques de cada pare o mare i poder individualitzar el procés educatiu

Proteasome inhibition reduces proliferation, collagen expression, and inflammatory cytokine production in nasal mucosa and polyp fibroblasts

Proteasome inhibitors, used in cancer treatment for their proapoptotic effects, have anti-inflammatory and antifibrotic effects on animal models of various inflammatory and fibrotic diseases. Their effects in cells from patients affected by either inflammatory or fibrotic diseases have been poorly investigated. Nasal polyposis is a chronic inflammatory disease of the sinus mucosa characterized by tissue inflammation and remodeling. We tested the hypothesis that proteasome inhibition of nasal polyp fibroblasts might reduce their proliferation and inflammatory and fibrotic response. Accordingly, we investigated the effect of the proteasome inhibitor Z-Leu-Leu-Leu-B(OH)2 (MG262) on cell viability and proliferation and on the production of collagen and inflammatory cytokines in nasal polyp and nasal mucosa fibroblasts obtained from surgery specimens. MG262 reduced the viability of nasal mucosa and polyp fibroblasts concentration- and time-dependently, with marked effects after 48 h of treatment. The proteasome inhibitor bortezomib provoked a similar effect. MG262-induced cell death involved loss of mitochondrial membrane potential, caspase-3 and poly(ADP-ribose) polymerase activation, induction of c-Jun phosphorylation, and mitogen-activated protein kinase phosphatase-1 expression. Low concentrations of MG262 provoked growth arrest, inhibited DNA replication and retinoblastoma phosphorylation, and increased expression of the cell cycle inhibitors p21 and p27. MG262 concentration-dependently inhibited basal and transforming growth factor-β-induced collagen mRNA expression and interleukin (IL)-1β-induced production of IL-6, IL-8, monocyte chemoattractant protein-1, regulated on activation normal T cell expressed and secreted, and granulocyte/macrophage colony-stimulating factor in both fibroblast types. MG262 inhibited IL-1β/tumor necrosis factor-α-induced activation of nuclear factor-κB. We conclude that noncytotoxic treatment with MG262 reduces the proliferative, fibrotic, and inflammatory response of nasal fibroblasts, whereas high MG262 concentrations induce apoptosis.
