RESUMO
Aim: The aim of the present study was to evaluate the effect of different vermicompost application rates on growth, protein and chlorophyll content in leaves of Moringa oleifera under water stress in a greenhouse experiment.Methodology: Soil samples and seeds were collected and characterized. Seedlings grown in a greenhouse in polyethylene bags with 4 kg of soil were subjected to water stress. After 90 days, agronomic variables, chlorophyll and protein content and peroxidase activity were estimated for each treatment and each condition in Moringa oleifera. Results: The results showed that under non-water stress conditions, the levels of vermicompost at a fertilization rate of 500 kg N ha-1 resulted in a significant increase in chlorophyll content, as compared to unamended soil. However, under waterlogging conditions, there was a significant difference between control and vermicompost treatments. Interpretation: The results indicated that addition of vermicompost to soil improved the growth and photosynthetic rate of Moringa oleifera under stress-free and water-deficit conditions. However, protein content only increased significantly when vermicompost was added at a fertilizer application rate of 500 kg N ha-1 both under waterlogging and deficit conditions
RESUMO
La Oficina de Comunicación a distancia (OCD) es una estructura creada en 1997 en el Hospital de Pediatría Juan P. Garrahan, con el objetivo de responder consultas a distancia y facilitar el seguimiento de pacientes, con la intención de evitar los traslados innecesarios. Ha dado respuesta a más de 25000 consultas. Actualmente, en el marco del Programa de Comunicación a Distancia (PCD), funcionan 88 OCD distribuidas en 12 de las 23 provincias argentinas. Se presentan resultados sobre una muestra de 148 consultas realizadas al Hospital Garrahan desde 6 provincias, que participaron de un estudio de tipo descriptivo, retrospectivo, cuali-cuantitativo. Éste permitió formular nuevas formas de registro de la tarea y elaborar indicadores cualicuantitativos para evaluar el PCD: consultas, motivo de consulta, tipo de paciente consultado, necesidad de la consulta, duración de la enfermedad al momento de la consulta, derivación sugerida, tiempo de respuesta. Se analizó el número de consultas y las sugerencias de derivación, mostrando las primeras un progresivo y significativo incremento desde la implementación del PCD. Con relación a los motivos de consulta, 84% correspondió a definición de diagnóstico y tratamiento, 16% a motivos de seguimiento e intercurrencias. 62% presentaba patologías crónicas. 95% de los pacientes fueron definidos como complejos. 79% correspondió a consultas definidas como imprescindibles. La derivación fue sugerida en el 54% de las consultas. La mediana del tiempo de respuesta fue de 48 horas. El bajo porcentaje atribuido a "motivos de seguimiento" evidencia la necesidad de profundizar estrategias para promoverlo. El PCD oficializó una modalidad de comunicación que canaliza prácticas anteriormente realizadas a través de vías informales, resignificando la gestión como acto asistencial. Contribuyó a la implementación de metodologías de evaluación conjunta de los indicadores considerados, que contemplan el contexto de la población con la que se trabaja (AU)
In 1997, the Outreach Communication Office (OCO) was created at the Pediatric Hospital Juan P. Garrahan with the aim of responding to consultations from remote places and facilitating follow-up of patients while avoiding unnecessary patient transportations. More than 25,000 consultations have been responded. Currently, within the framework of the Program of Outreach Communication (POC), 88 OCO's are operating distributed over 12 of the 23 Argentine provinces. Here we present the results of a sample of 148 consultations made at the Garrahan Hospital from six provinces that participated in a descriptive, retrospective, qualitative and quantitative study. The study allowed formulation of new methods of task registration and the development of qualitative and quantitative indicators to evaluate the POC: consultations, reason for consultation, type of patient, urgency of the consultation, disease duration until the moment of consultation, suggested referral, and time to response. The number of consultations and suggestions for referral were analyzed showing a progressive and significant increase of the former since the implementation of the POC. Of the reasons for consultation, 84% was related to definition of diagnosis and treatment, 16% to follow-up and intercurrencies. Of all patients, 62% had chronic diseases and 95% were considered complex patients. Of the consultations, 79% were defined as essential and 54% of the patients were referred to specialists. Mean time to response was 48 hours. The low percentage of consultations for "reasons of follow-up" reveals the need to develop strategies to encourage this modality. The POC has officialized a means of communication channeling practices that previously were informal giving a new meaning to the concept management in health care. The POC has contributed to the implementation of methodologies for the assessment of global markers taking into account the context of the population in question (AU)
