Metabolic syndrome: definitions and controversies

Metabolic syndrome (MetS) is a complex disorder defined by a cluster of interconnected factors that increase the risk of cardiovascular atherosclerotic diseases and diabetes mellitus type 2. Currently, several different definitions of MetS exist, causing substantial confusion as to whether they identify the same individuals or represent a surrogate of risk factors. Recently, a number of other factors besides those traditionally used to define MetS that are also linked to the syndrome have been identified. In this review, we critically consider existing definitions and evolving information, and conclude that there is still a need to develop uniform criteria to define MetS, so as to enable comparisons between different studies and to better identify patients at risk. As the application of the MetS model has not been fully validated in children and adolescents as yet, and because of its alarmingly increasing prevalence in this population, we suggest that diagnosis, prevention and treatment in this age group should better focus on established risk factors rather than the diagnosis of MetS

O potencial pedagógico da Hora do Conto para o desenvolvimento da Comunicação Oral

O presente relatório é produto de um projeto de investigação que pretendeu caracterizar a adequação e dinamização da hora do conto com a finalidade de promover o desenvolvimento da comunicação oral, implementada numa sala de 3/4 anos e a adequação didática de um processo de intervenção educativa de estratégias para a promoção do desenvolvimento da Oralidade (incidindo na dinamização da hora conto) implementado numa turma de 3.º ano do 1.º Ciclo do Ensino Básico. Tendo consciência da desvalorização que é atribuída à temática em análise, acreditamos que os profissionais de educação se tornam responsáveis pelo desenvolvimento e aperfeiçoamento das capacidades de comunicação das crianças/alunos. Neste sentido, consideramos que foi extremamente importante investir neste domínio e nas competências a ele associado, nas vertentes de compreensão e expressão orais. Para atingir os objetivos delineamos, planificamos, construímos, aplicamos e avaliamos em sala de aula, um conjunto de intervenções educativas adotando como estratégia principal a dinamização da hora do conto. Assim sendo, podemos verificar através dos resultados obtidos, que efetivamente, a hora do conto e a utilização de diferentes estratégias para a dinamização da mesma, contribuíram positivamente para o desenvolvimento das competências orais dos intervenientes, potenciando melhorias, a vários níveis, nomeadamente na vertente de compressão e de expressão oral dos dois grupos de aplicação.This report is the product of a research project that aimed to characterize the adequacy and dynamization of the story time with the purpose of promoting the development of oral communication, implemented in a 3/4 year classroom and the didactic adequacy of a process of educational intervention strategies to promote the development of Orality (focusing on the dynamization of the story time) implemented in a 3rd year class of the 1st Cycle of Basic Education. Being aware of the devaluation that is attributed to the theme under analysis, we believe that education professionals become responsible for the development and improvement of communication skills of children/students. In this sense, we believe that it was extremely important to invest in this field and in the skills associated with it, in the areas of understanding and oral expression. In order to achieve the objectives, we delineate, plan, build, apply and evaluate in the classroom, a set of educational interventions adopting as the main strategy the dynamization of the story time. Therefore, we can verify through the results obtained, that effectively, the story time and the use of different strategies for the dynamization of the tale, contributed positively to the development of the oral skills of the participants, enhancing improvements, at various levels, particularly in the compression and oral expression of the two groups of application.

Cardiovascular risk factors in adult patients with multisystem Langerhans-cell histiocytosis: evidence of glucose metabolism abnormalities.

BACKGROUND: Langerhans-cell histiocytosis (LCH) is a rare disease with features of chronic inflammation and it may also induce hypopituitarism, conditions associated with an increased risk of cardiovascular diseases. AIM: Cardiovascular and metabolic risk profile investigation in multisystem LCH patients with and without anterior pituitary deficiency. DESIGN: Prospective, observational study. METHODS: Fourteen adult patients with LCH, 7 with and 7 without anterior pituitary deficiency, and 42 controls matched for age, body mass index (BMI) and smoking. Cardiovascular risk factors were estimated in all subjects: glucose and lipid profile, mathematical indices of insulin resistance (IR), blood pressure, structural arterial and functional endothelial properties (intima-media thickness, brachial artery flow-mediated dilatation). Cardiovascular risk factors were estimated in the three groups studied; the effect of disease activity and/or treatment was also determined in patients with LCH. RESULTS: Ten patients had diabetes insipidus, and 7 anterior pituitary hormone deficiencies: 8 patients had active disease and 11 had received systemic treatment. No difference was observed between the study groups in vascular parameters, in lipid profile or in blood pressure. However, the insulin resistance index GIR was decreased in patients with LCH without anterior pituitary deficiency compared to controls (P = 0.033). Three patients had impaired glucose tolerance and one diabetes mellitus type 2. These patients were older and had active disease; there was no association with hypopituitarism and/or previous treatment. CONCLUSION: Adults patients with LCH have abnormalities of glucose metabolism that tend to occur in patients with active disease, and may be a consequence of the pro-inflammatory state
