Objective: report the experience of applying the theoretical data saturation technique in qualitative research with schoolchildren. Method: critical reading of primary sources and compilation of raw data, followed by thematic grouping through colorimetric codification and allocation of themes/types of statements in charts to find theoretical saturation for each grouping. Results: colorimetric codification occurred according to previously established themes: bodily hydration; physical activities and play; handling of sickle-cell disease; feeding and clothing. On the eleventh interview, it was possible to reach the theoretical saturation of themes, with four additional interviews being performed. Conclusion: this experience report enabled the description of the five sequential steps for identification of theoretical data saturation in qualitative research conducted with schoolchildren.

Purpose: to develop and validate a nursing process application in a neonatal intensive care unit. Method: a methodological study, conducted in a university hospital in southeastern Brazil from January 2017 to February 2018, divided into four stages: definition of requirements and elaboration of the conceptual model; generation of implementation and prototyping alternatives; testing and implementation. The app was developed based on Wanda Horta's Basic Human Needs and International Classification for Nursing Practice and following the User Centered Design method and the standards of the Brazilian Association of Software Engineering Technical Standards for IOS and Android platforms. The product was evaluated and validated by nurses for functional suitability, reliability, usability, performance efficiency, compatibility and safety. Results: the CuidarTech NeoProcesso de Enfermagemapp has screens that integrate the elements for history, diagnosis and nursing interventions. According to the judges' evaluation, it has functional adequacy, reliability, usability, performance efficiency, compatibility and safety. Conclusion: the app designed and validated by nurses is a computerized instrument that contains the stages of the nursing process: history, diagnoses and interventions, organized by Basic Human Needs and following the taxonomy of the International Classification for Nursing Practices. It relates information of newborns admitted to Neonatal Intensive Care Units and the nursing process, being able to provide quality, effectiveness, safety and personal satisfaction to the nurse's care.

Dentre os patógenos veiculados pelas sementes e grãos do milho (Zea mays L.), Fusarium proliferatum causa tombamento e morte de plântulas, podridão de raízes, de colmo, de espiga e grãos. Assim, o tratamento de sementes mostra-se como importante medida para preservar a qualidade. O objetivo do presente trabalho foi avaliar a atividade antifúngica de diferentes concentrações dos extratos de alho (Allium sativum L.) e capim-santo (Cymbopogon citratus Stapf.) visando o controle de F. proliferatum em sementes de milho e observar os efeitos dos tratamentos sobre a germinação de sementes, sanidade e desenvolvimento das plântulas. A partir de grãos de milho, foi feito o isolamento de F. proliferatum, que foi cultivado em meio BDA. Foram avaliados os efeitos dos extratos de alho e capim santo sobre crescimento micelial, nas concentrações 0,5%, 1,0%, 2,5%, 5,0% e 10,0%, medindo-se os diâmetros das colônias do fungo durante oito dias. Esporos de F. proliferatum foram imersos em soluções dos extratos, nas concentrações mencionadas, e avaliados, quanto à germinação de conídios, às 6, 12, 18 e 24 horas de imersão. Sementes de milho foram tratadas em soluções dos extratos e inoculadas com F. proliferatum, sendo avaliada quanto à incidência do fungo, percentagem de germinação e incidência de tombamento e podridão do colmo das plântulas. Os extratos empregados reduziram a taxa de crescimento micelial e a germinação dos esporos, como também a incidência de F. proliferatum em grãos de milho. O extrato de alho, a partir da concentração 2,5%, mostrou maior eficiência em relação aos demais tratamentos. Os produtos vegetais aumentaram a germinação das sementes e também controlaram o tombamento e a podridão do colmo das plântulas de milho.

Papaya is one of the most grown and consumed fruits in the world. However, post-harvest diseases are responsible for more than 50 % of losses, including anthracnose, caused by Colletotrichum gloesporioides, which promotes necrotic and rounded lesions and reduces fruit quality. Alternative products have been widely investigated in the control of pathogens. This study aimed at evaluating the efficiency of elicitors in the control of anthracnose, as well as their effect on post-harvest quality, in papaya fruits. The fruits were disinfested and immersed in acibenzolar-S-methyl, potassium phosphite, Rocksil^®, Agro-mos^®, Ecolife^®, sterilized distilled water and prochloraz, inoculated with C. gloesporioides and stored. Potassium phosphite, Rocksil^®, Ecolife^® and prochloraz resulted in the smallest diameters of lesions, and, consequently, in a greater protection and enzymatic activity. The fruits treated with Rocksil^® and Ecolife^® maintained the lowest levels of soluble solids and titratable acidity. Potassium phosphite, Rocksil^® and Ecolife^® are effective in controlling anthracnose, do not change the appearance and preserve the post-harvest quality of papaya fruits, and, therefore, may be used as an alternative to commercial fungicides.

Objectives: to develop and validate management tools for the systematization of nursing care for children with pressure injuries. Methods: methodological study in which the focus group technique was used for validation of tools in three different groups of 17 nurses. Conducted in April and May 2018 at a large pediatric hospital. Results: two management tools were developed. The first was the Nursing care systematization instrument for children with pressure injury with three parts: a) risk factors; b) Psychobiological Basic Human Needs; c) signs of wound infection. The second was the Flowchart of pressure injury risk and prevention in pediatric patients with three categories: a) risk factors; b) Braden Q scale; c) nursing care. Final Considerations: the tools will support nurses in the care of children with pressure injuries by aiming at an individualized and systematized assessment based on a theoretical framework.
