Many time series with trend and seasonal pattern are successfully modeled and forecasted by the airline model of Box and Jenkins; however, this model neglects the presence of nonlinearity on data. In this paper, we propose a new nonlinear version of the airline model; for this, we replace the moving average linear component by a multilayer perceptron neural network. The proposed model is used for forecasting two benchmark time series; we found that the proposed model is able to forecast the time series with more accuracy that other traditional approaches.

Forecasting electricity prices in liberalized, deregulated markets has always been considered a difficult task, due to the number of factors that govern prices and to their complexity. This article predicts the average monthly prices for Colombian electricity market contracts by using a novel neural network known as the support vector machine. Forecasts obtained using a multilayer perceptron are compared to forecasts obtained using an ARIMA model. The results show that the support vector machine better captures the intrinsic dynamics of the time series and is able to make more precise forecasts considering a 12-month horizon.

This paper intends to show the combination of therapeutical strategies in the treatment of long evolution food disorders. This fashion of work entitled "Modelo Santa Cristina" is based on several theoretical paradigms: Enabling Model, Action Control Model, Change Process Transtheoretical Model and Cognitive-Behavioural Model (Cognitive Restructuring and Learning Theories). Furthermore, Gestalt, Systemic and Psychodrama Orientation Techniques. The purpose of the treatment is both the normalization of food patterns and the increase in self-knowledge, self- acceptance and self-efficacy of patients. The exploration of ambivalence to change, the discovery of the functions of symptoms and the search for alternative behaviours, the normalization of food patterns, bodily image, cognitive restructuring, decision taking, communication skills and elaboration of traumatic experiences are among the main areas of intervention.

Aripiprazole is a dopamine partial agonist antipsychotic drug that has just been approved in Europe for its use in the treatment of acute mania and for the prevention of manic episodes in bipolar disorder. Its efficacy in mania is superior to that of placebo, both as monotherapy and as adjunctive therapy, and comparable to that of haloperidol and lithium. From the safety perspective it is remarkable that it is not highly sedative and does not impair the metabolic parameters. The advantages of a non-sedative and metabolically neutral antimanic drug are particularly relevant in the long-term, due to their impact on cognition and quality of life. The experience on its use in routine clinical practice indicates that in order to avoid phenomena such as activation, abrupt worsening or akathisia, it is recommendable to start treatment with low doses and to increase them progressively, especially in those patients who are already receiving other drugs; moreover, it is advisable not to stop abruptly any ongoing treatment, unless there is an emergency, to transiently prescribe a concomitant benzodiazepine, and to maintain the dose that proved efficacious during the short term treatment during maintenance therapy.

In Psiconeuroendochrinology there's a scarcity of knowledge of hypothalamic-pituitarythyroid axis (HPT) in relation to bipolar disorder (BD) and neuropsychological functions. The aim of this study is to review the current state of the following issues: (1) neuropsychological dysfunctions in BD, as well as their hypothetic aetiology; (2) response of HPT in each phase of BD, and, finally, (3) connection between alterations in HPT and neuropsychological deficits. After a careful analysis of the scientific literature, we conclude that more systematic research is needed because most of the issues, such as the role of HPT in BD and the implication of HPT in neuropsychological deficits, still remain unclear.

Introduction. Our aim was to evaluate treatment safety, tolerability, efficacy and compliance of long-acting injectable risperidone (LAIR) as maintenance treatment in a bipolar and schizoaffective inpatients sample with torpid course due to poor compliance with oral therapy. Methods. 22 inpatients, 14 with a diagnosis of bipolar disorder and 8 with a diagnosis of schizoaffective disorder, were included in this study. They were treated with LAIR, 1 dose every 14 days, and were evaluated for 40 weeks with the Young Mania Rating Scale (YMRS), Hamilton Scale for Depression (HAM-D), UKU-Side Effect Rating Scale and Clinical Global Impression Severity of Illness scales (CGI). Results. Average YMRS scores were reduced significantly from 10.5 at baseline interview to 2.5 at week 40 (p < 0.001). HAM-D and UKU scales did not reach a statistically significant reduction. CGI-S scores were reduced from 3.8 at baseline to 1.5 at week 40 (p < 0.001). Conclusions. LAIR could be an effective maintenance therapy for bipolar and schizoaffective patients with poor compliance with oral treatment. [ABSTRACT FROM AUTHOR]
