RESUMO
To determine the effects of pre-harvest calcium (Ca), magnesium (Mg) and potassium (K) spraying on the antioxidant activity and capacity of hazelnut (Corylus avellana L.) shells, as an approach to sustain the utilization of the main residue derived from this industry, four commercial hazelnut (Tonda di Giffoni) orchards located in Southern Chile (Cunco, Gorbea, Perquenco and Radal), during the 2018/19 season were sprayed three times with five combinations of Ca (300 and 600 mg L-1), Mg (300 and 600 mg L-1) and K (300 and 600 mg L-1). Yield components were determined in harvested whole nuts, whereas Ca, Mg and K concentrations, as well as total phenolic compounds, free radical scavenging antioxidant activity, and oxygen radical absorbance capacity, were determined in shells. All spray treatments with both Ca, Mg and K combinations showed a significant interaction between locality and treatment (L × T) on increased stabilized nut yield (kg ha-1) in comparison with the control treatments, whereas nut quality was differentially affected by treatment and orchard locality, thus confirming a significant L × T relationship regarding nut length and kernel yield. However, locality showed a major effect on kernels and shells. A significant relationship was determined between locality and the Ca, Mg and K spraying (L × T) concerning antioxidant compounds such as phenolics, whose amounts exceeded those of the control treatments by three times. Antioxidant capacity and activity in shells showed a significant L × T relationship, and nutshells collected from Cunco showed remarkably (3-4 times) higher levels of these factors than the other evaluated localities. Interactions between spray treatment and orchard location were responsible for the different values obtained in the experiments, confirming the influence of the environment on the efficacy of the treatments. Finally, these shells are worth further study as an interesting residue of the hazelnut industry due to their nutritional and antioxidant properties.
RESUMO
INTRODUCCIÓN: Los programas de control prenatal se constituyen en una estrategia de atención primaria que forma parte de un proceso de protección específica destinado a fomentar la salud de la madre, el feto y la familia, en este sentido, el profesional de enfermería cumple un rol fundamental dentro del equipo de salud. Por ello, el objetivo del presente trabajo fue evaluar la atención de enfermería en un Programa de Control Prenatal de una Institución Prestadora de Servicios de Salud de Malambo Atlántico desde la opinión de las gestantes. METODOLOGÍA: Se desarrolló un estudio cuantitativo, de tipo descriptivo y transversal, en el que se encuestaron 20 gestantes pertenecientes al programa de control prenatal, teniendo en cuenta aspectos éticos y metodológicos de rigor. RESULTADOS: Los aspectos mejor valorados por las gestantes en la atención prenatal fueron: la información que la enfermera le proporciona y la vigilancia de los signos vitales. Los aspectos peor valorados fueron: la vigilancia de la dieta y la educación con respecto al cuidado futuro de su hijo. El 45% manifestó que la atención de enfermería durante el control prenatal fue buena. DISCUSIÓN: Las gestantes perciben buena atención de enfermería en el programa de control prenatal, pero requieren mayor educación sobre signos de alarma, cuidado del bebé y hábitos alimenticios. Hallazgo coherente con estudios previos revisados. CONCLUSIONES: La Institución necesita establecer estrategias de mejoramiento de la calidad de la atención para fortalecer las acciones de demanda inducida y protección específica.
INTRODUCTION: Prenatal care programs constitute a primary care strategy that is part of a specific protection process aimed at promoting the health of the mother, the fetus and the family. In this sense, the nursing professional plays a role fundamental within the health team. Therefore, the objective of the present study was to evaluate the nursing care in a Prenatal Control Program of a Health Services Provider Institution of Malambo -Atlántico from the opinion of the pregnant women. METHODOLOGY: A quantitative, descriptive and cross-sectional study was conducted in which 20 pregnant women from the prenatal control program were surveyed, taking ethical and methodological aspects into account. RESULTS: The aspects most valued by pregnant women in prenatal care were: information provided by the nurse and vital signs surveillance. The least valued aspects were: monitoring of diet and education regarding the future care of your child. 45% stated that nursing care during prenatal care was good. DISCUSSION: Pregnant women perceive good nursing care in the prenatal control program, but require more education about signs of alarm, baby care and eating habits. Findings consistent with previous studies reviewed. CONCLUSIONS: The Institution needs to establish strategies to improve the quality of care to strengthen the actions of induced demand and specific protection.
