Knowledge of nursing staff before and after training on incontinence-associated dermatitis / Conocimientos del personal de enfermería antes y después de la formación sobre la dermatitis asociada a la incontinencia / Conhecimento da equipe de enfermagem antes e após capacitação sobre dermatite associada à incontinência

ABSTRACT Objective: To verify the knowledge of nursing staff before and after training on incontinence-associated dermatitis. Method: A study before and after an educational intervention carried out with nursing staff from the medical and surgical clinics and intensive care unit of the university hospital in June 2023. The training took place over three meetings. Data was collected using a questionnaire administered immediately before and after the training. McNemar's test for dependent samples was used to compare before and after training. Results: 25 nurses and 14 nursing technicians took part. The items that showed statistical significance were related to the identification and correct differentiation of dermatitis associated with incontinence and pressure injury; and the correct way to sanitize the skin. Conclusion: The training of the nursing team made it possible to assess their knowledge of how to identify, prevent and treat incontinence-associated dermatitis.

RESUMEN Objetivo: Verificar los conocimientos del personal de enfermería antes y después de la formación sobre la dermatitis asociada a la incontinencia. Método: Estudio antes y después de una intervención formativa realizada con personal de enfermería de las clínicas médicas y quirúrgicas y de la unidad de cuidados intensivos de un hospital universitario en junio de 2023. La formación se impartió en tres sesiones. Los datos se recogieron mediante un cuestionario aplicado inmediatamente antes y después de la formación. Se utilizó la prueba de McNemar para muestras dependientes para comparar antes y después de la formación. Resultados: Participaron 25 enfermeras y 14 técnicos de enfermería. Los ítems que mostraron significación estadística estaban relacionados con la identificación y correcta diferenciación de la dermatitis asociada a la incontinencia y al daño por presión; y la forma correcta de higienizar la piel. Conclusión: La formación del equipo de enfermería permitió evaluar los conocimientos del equipo de enfermería sobre cómo identificar, prevenir y tratar la dermatitis asociada a la incontinencia.

RESUMO Objetivo: Verificar o conhecimento da equipe de enfermagem antes e após capacitação sobre dermatite associada à incontinência. Método: Estudo antes e depois de uma intervenção educativa realizado com profissionais da equipe de enfermagem das clínicas médicas, cirúrgicas e unidade de terapia intensiva do hospital universitário, no mês de junho de 2023. A capacitação ocorreu durante três encontros. Os dados foram coletados por meio de questionário, aplicado imediatamente antes e após a capacitação. Para a comparação do antes e após capacitação, foi realizado o teste de McNemar para amostras dependentes. Resultados: Participaram 25 enfermeiros e 14 técnicos de enfermagem. Os itens que apresentaram significância estatística foram relacionados à identificação e à diferenciação correta da dermatite associada à incontinência e lesão por pressão; e a forma correta para higienização da pele. Conclusão: A capacitação da equipe de enfermagem permitiu avaliar o conhecimento da equipe de enfermagem para identificar, prevenir e tratar a dermatite associada à incontinência.

CagA phosphorylation EPIYA-C motifs and the vacA i genotype in Helicobacter pylori strains of asymptomatic children from a high-risk gastric cancer area in northeastern Brazil

Helicobacter pylori infection is one of the most common infections worldwide and is associated with gastric diseases. Virulence factors such as VacA and CagA have been shown to increase the risk of these diseases. Studies have suggested a causal role of CagA EPIYA-C in gastric carcinogenesis and this factor has been shown to be geographically diverse. We investigated the number of CagA EPIYA motifs and the vacA i genotypes in H. pylori strains from asymptomatic children. We included samples from 40 infected children (18 females and 22 males), extracted DNA directly from the gastric mucus/juice (obtained using the string procedure) and analysed the DNA using polymerase chain reaction and DNA sequencing. The vacA i1 genotype was present in 30 (75%) samples, the i2 allele was present in nine (22.5%) samples and both alleles were present in one (2.5%) sample. The cagA-positive samples showed distinct patterns in the 3’ variable region of cagA and 18 of the 30 (60%) strains contained 1 EPIYA-C motif, whereas 12 (40%) strains contained two EPIYA-C motifs. We confirmed that the studied population was colonised early by the most virulent H. pylori strains, as demonstrated by the high frequency of the vacA i1 allele and the high number of EPIYA-C motifs. Therefore, asymptomatic children from an urban community in Fortaleza in northeastern Brazil are frequently colonised with the most virulent H. pylori strains. .
