[Nutrition impact on insomnia treatment]. / Impacto de la alimentación en la lucha contra el insomnio.

INTRODUCTION: Introduction: insomnia represents a growing and important health problem. If it persists, it could have a negative impact in people's welfare. Nowadays we have a wide range of techniques to measure and analyze sleep quality and quantity. Objectives: to demonstrate the impact of nutrition in sleep disorders. Methods: bibliographic review selecting the most relevant papers related to nutrition and its impact on sleep. Results: there is a direct correlation between some food or supplements and sleep quality and quantity. In addition, there exist some nutritional maneuvers that can help to prevent or solve some sleep disorders. The relationship between tryptophan and melatonin with the induction and maintenance of the sleep is clear, but vitamins, minerals, macronutrients and some dietetic habits can also have an impact. Conclusions: nutrition can have a relevant effect in the prevention and resolution of sleep disorders. Further studies are necessary to assess the real impact of nutritional treatments in insomnia.

INTRODUCCIÓN: Introducción: el insomnio representa un creciente problema de salud, con repercusiones importantes si es mantenido a largo plazo, ya que puede impactar en la salud del individuo. Actualmente se dispone de técnicas de registro del sueño y cuestionarios de análisis que facilitan la realización de estudios de calidad del sueño. Objetivos: demostrar el impacto de la nutrición en los trastornos del sueño. Métodos: revisión bibliográfica con selección de los artículos más relevantes relacionados con la nutrición y el insomnio. Resultados: existe una relación directa entre ciertos alimentos o suplementos y la calidad y cantidad del sueño, de esta manera se identifican actuaciones nutricionales que pueden ayudar a resolver o a prevenir ciertos trastornos del sueño. Parece clara la relación del triptófano y la melatonina con la inducción y el mantenimiento del sueño, pero las vitaminas, los minerales, los macronutrientes y ciertos hábitos dietéticos pueden influir también de forma directa. Conclusiones: la nutrición parece tener un papel relevante en la prevención y resolución del insomnio, si bien futuros estudios dirigidos han de aportar más evidencia al respecto.

Posttraumatic growth in pediatric intensive care personnel: Dependence on resilience and coping strategies.

OBJECTIVE: Staff in pediatric intensive care units (PICU) are inherently exposed to potentially traumatic events. Posttraumatic growth (PTG) is the occurrence of positive changes after experiencing a traumatic event. This study aims (a) to evaluate the prevalence of PTG in PICU staff, and whether their scores are different from those reported by professionals working in other pediatric units, (b) to explore the role of resilience and coping strategies in predicting PTG, and (c) to explore the relation of demographic and work-related variables with PTG. METHOD: Participants of this multicentric, cross sectional study were 298 PICU workers and 189 professionals working in noncritical pediatric units. They completed the Brief Resilience Scale, a Coping Strategies Questionnaire, the Posttraumatic Growth Inventory (PTGI), and provided demographic and work-related information. RESULTS: Of PICU staff, 68.8% experienced growth to a "great" or "very great" degree in at least one of the PTGI's dimensions. Higher PTG was reported following the death of a child or after a recent conflict with a work colleague. PICU workers and noncritical pediatric staff showed equivalent PTG levels. Multigroup path analysis with latent variables showed that emotion-focused coping was related to PTG only in PICU staff, whereas problem-focused coping was related to PTG in both groups. The relation between resilience and PTG was not significant. CONCLUSIONS: Work-related trauma can act as a catalyst for positive posttrauma changes. Modifying coping strategies may be a way to foster PTG in health care providers. (PsycINFO Database Record
