Environmental awareness and energy policies led to decarbonization targets, fostering the adoption of distributed energy resource in the distribution network. Particularly, photovoltaic systems have been gaining momentum due to cost-competitive option and financial benefits. However, traditional distribution networks were not designed for intermittency in power generation. This poses technical issues such as reverse power flow, overvoltage, and thermal overloading. Furthermore, the growth in intermittency and variability of distributed energy resources increases the uncertainty, hence, it brings challenges for the operation, planning, and investment decisions. In this context, probabilistic methods to cater for these uncertainties are essential to address this issue. This paper presents a probabilistic power flow method based on point estimate method combined Edgeworth expansion for high penetration of photovoltaic generation in distribution networks. Normal distribution and Beta distribution are considered for load and solar irradiation modelling, respectively. The method is assessed for different cases using the IEEE 33-bus distribution test system with photovoltaic systems installation. The point estimate method combined Edgeworth expansion provided satisfactory results with lower computational effort and high fitting accuracy of statistical information compared to Monte Carlo simulation.

Resumen: El uso de apoyo nutricional ambulatorio, enteral o parenteral, ha sido un paso necesario en la opti mización del soporte nutricional en pacientes, que, por diversas patologías, no logran cumplir con sus requerimientos por vía oral (VO). En el presente artículo se presentan las recomendaciones de la Rama de Nutrición, dirigidas a los equipos de salud que atienden pacientes pediátricos, que requieran alimentación enteral por un tiempo prolongado. Su objetivo general es entregar pautas para un co rrecto manejo en estos pacientes. Se describe la conformación ideal del equipo de salud para atención y seguimiento de dichos pacientes, los criterios de ingreso al programa y su forma de evaluación en el tiempo. Además, se describen características generales de la alimentación enteral, vías de admi nistración, fórmulas enterales disponibles, complicaciones de este soporte nutricional y por último monitorización y seguimiento del paciente.

Abstract The use of home enteral or parenteral nutrition has been a necessary step in the optimization of nu tritional support in patients who, due to several diseases, fail to meet their nutritional requirements by oral feeding. This article presents the recommendations of the Chilean Pediatric Society Nutritio nal Branch, aimed at health teams that treat pediatric patients who require enteral feeding for a long time. The general objective is to provide guidelines for the proper management of these patients. It describes the ideal conformation of the health team for the care and follow-up of those patients, the program admission criteria, and its evaluation method over time. In addition, it describes general characteristics of enteral feeding, routes of administration, available enteral formulas, complications, and patient follow-up.

La prevalencia de dislipidemias ha aumentado en niños y adolescentes, muchas de ellas asociadas al incremento de la obesidad. Puesto que constituyen un factor de riesgo cardiovascular futuro, deben conocerse las bases de su tratamiento. En la gran mayoría de los pacientes, éste consiste en cambios de estilo de vida, con dieta específica y aumento de la actividad física, presentando habitualmente una respuesta favorable. Solo una minoría requiere tratamiento medicamentoso, el que debe ser realizado por especialista en el contexto de una evaluación completa del perfil de riesgo cardiovascular, con la inclusión del paciente y su familia. Sin embargo, la prevención de los factores de riesgo cardiovascular debe ser realizada por todos los miembros del equipo de salud. Este artículo presenta las recomendaciones de la Rama de Nutrición de la Sociedad Chilena de Pediatría para el diagnóstico, tamizaje y tratamiento de las dislipidemias en la niñez.

Background: Prediabetes is a high-risk state for diabetes development, but little is known about the factors associated with this state. The aim of the study was to identify modifiable risk factors associated with the presence of prediabetes in men and women. Methods: Cohort Study in Primary Health Care on the Evolution of Patients with Prediabetes (PREDAPS-Study) is a prospective study on a cohort of 1184 subjects with prediabetes and another cohort of 838 subjects without glucose metabolism disorders. It is being conducted by 125 general practitioners in Spain. Data for this analysis were collected during the baseline stage in 2012. The modifiable risk factors included were: smoking habit, alcohol consumption, low physical activity, inadequate diet, hypertension, dyslipidemia, and obesity. To assess independent association between each factor and prediabetes, odds ratios (ORs) were estimated using logistic regression models. Results: Abdominal obesity, low plasma levels of high-density lipoprotein cholesterol (HDL-cholesterol), and hypertension were independently associated with the presence of prediabetes in both men and women. After adjusting for all factors, the respective ORs (95% Confidence Intervals) were 1.98 (1.41-2.79), 1.88 (1.23-2.88) and 1.86 (1.39-2.51) for men, and 1.89 (1.36-2.62), 1.58 (1.12-2.23) and 1.44 (1.07-1.92) for women. Also, general obesity was a risk factor in both sexes but did not reach statistical significance among men, after adjusting for all factors. Risky alcohol consumption was a risk factor for prediabetes in men, OR 1.49 (1.00-2.24). Conclusions: Obesity, low HDL-cholesterol levels, and hypertension were modifiable risk factors independently related to the presence of prediabetes in both sexes. The magnitudes of the associations were stronger for men than women. Abdominal obesity in both men and women displayed the strongest association with prediabetes. The findings suggest that there are some differences between men and women, which should be taken into account when implementing specific recommendations to prevent or delay the onset of diabetes in adult population.

Este artículo presenta las recomendaciones de la Rama de Nutrición de la Sociedad Chilena de Pediatría para el diagnóstico, tamizaje y tratamiento de las dislipidemias en la niñez. The prevalence of dyslipidemia has dramatically increased in children and adolescents, and many of these cases are associated with increased obesity. As this condition represents cardiovascular risk in the future, the bases of its treatment should be widely known. In the vast majority of patients, there will be lifestyle changes, specific diet and increased physical activity, usually all of these resulting in a favorable response. Only a minority will require drug treatment, which must be prescribed by a specialist in the context of a comprehensive cardiovascular risk assessment, including the patient and his family. The prevention of cardiovascular risk factors should be performed by all members of the health team. This article presents the recommendations of the Nutrition specialists of the Chilean Society of Pediatrics for screening, diagnosis and treatment of dyslipidemia in childhood.
