RESUMEN
BACKGROUND: Helicobacter pylori is detected by pathogen recognition receptors including toll-like receptors (TLR) and nucleotide-binding oligomerization domain (NOD)-like receptors, eliciting an innate immune response against this bacteria. The aim of this study was to assess if polymorphisms of TLR2, TLR4, TLR5, NOD1 and NOD2 genes are associated with gastric cancer, in particular in individuals infected with H. pylori. RESULTS: A case-control study of 297 gastric cancer patients and 300 controls was performed to assess the association of 17 polymorphisms. Analyses performed under the allele model did not find association with gastric cancer. However, NOD1 rs2075820 (p.E266K) showed association with intestinal-type gastric cancer among H. pylori infected subjects (OR = 2.69, 95% CI 1.41-5.13, p = 0.0026). The association was not statistically significant in diffuse-type gastric cancer cases (OR = 1.26, 95% CI 0.63-2.52, p = 0.51). When the analyses were performed in patients carrying H. pylori strains harboring the cag pathogenicity island (cagPAI), we noticed significant association with NOD1 rs2075820 (OR = 4.90, 95% CI 1.80-3.36, p = 0.0019), in particular for intestinal-type gastric cancer cases (OR = 7.16, 95% CI 2.40-21.33, p = 4.1 × 10- 4) but not among diffuse-type gastric cancer cases (OR = 3.39, 95% CI 1.13-0.10, p = 0.03). CONCLUSIONS: NOD1 rs2075820 increases the risk of intestinal-type gastric cancer among individuals infected with H. pylori, particularly in those harboring the cagPAI.

RESUMO Objetivo: construir e validar um instrumento para monitorar a qualidade dos registros de enfermagem no Programa de Assistência Domiciliar (PAD) em um hospital universitário. Método: estudo metodológico envolvendo a elaboração de um manual e submetido à validação de conteúdo por seis juízes sob consenso ≥ 80%. A coleta ocorreu em 2012 por meio de questionário contendo: evolução de enfermagem, diagnóstico e prescrição de enfermagem e normas para os registros da equipe de enfermagem preconizadas pelo Conselho Regional de Enfermagem-SP e pela instituição. Os itens do manual foram julgados de acordo com as variáveis - relevância, pertinência, clareza e simplicidade. Resultados: das 39 proposições 100% atingiram consenso ≥ 80% em relevância, pertinência e clareza; 92,3% em simplicidade. Os itens sono/repouso, mobilidade e checagem nas atividades prescritas não atingiram consenso mínimo favorável, sendo aprimorados pelas sugestões dos juízes. Conclusão: acreditamos que o instrumento possibilitará a melhoria dos processos de trabalho no PAD. .
RESUMEN Objetivo: construir y validar un instrumento para monitorear la calidad del registros de enfermería en Programa de Atención Domiciliaria (PAD) de un Hospital Universitario. Metodo: estudio metodológico. Fue construido un manual y sometió a validación de contenido por seis jueces bajo el consenso ≥80%. La recogida currió en 2012, con un cuestionario que contiene: evolución de enfermería, diagnóstico y prescripción de enfermería y normas para los registros del personal de enfermaria estabelecidas por Consejo Regional de Enfermería-SP y por la institución. Los artículos del manual fueran juzgadso conforme las variables relevancia, pertinencia, claridad y sencillez. Resultados: de las 39 proposiciones 100% alcanzó consenso ≥ 80% en la relevancia, pertinencia y claridad; 92,3% en la simplicidad. Los itens sueño/resto, movilidad y verificar las actividades prescritas no alcanzó consenso favorable, siendo mejoradas por las sugerencias de los jueces. Conclusión: creemos que el instrumento permitirá la mejora de los procesos de trabajo en PAD. .
ABSTRACT Objective: to build and validate an instrument aimed at monitoring the quality of nursing records in the Home Care Program (HCP) of a university hospital. Method: methodological study involving the elaboration of a manual, whose content was later submitted to six experts for validation, reaching a ≥ 80% consensus. The data collection process was carried out in 2012 by means of a questionnaire comprised of the following issues: nursing evolution, nursing diagnosis, and nursing prescription, and standards for the nursing team recommended by the Regional Nursing Council of São Paulo and by the assessed institution. Manual items were judged according to the following variables: relevance, pertinence, clarity and simplicity. Results: of the 39 propositions, 100% achieved ≥ 80% agreement in the relevance, pertinence and clarity variables; 92.3% in the simplicity variable. Sleep/rest, Mobility and Check-out variables did not reach a favorable minimum consensus in the prescribed activities and were improved following suggestions from the experts. Conclusion: we believe that the instrument will enable the improvement of the HCP’s work process. .
