Education for health: alcohol and young aged school teenagers

Introduction: Alcohol consumption starts at an early age in Portuguese people. Health problems and risk behavior associated with excessive consumption can be prevented or highly reduced through effective school programs. Health professionals, such as biomedical scientists, (BSc), are important in promoting healthy lifestyles through the transmission of knowledge. Objective: Explore the role of the BSc in promoting health via intervention and clarification actions, (ICA), with 9th grade students from Agrupamento de Escolas da Portela e Moscavide (AEPM) and Visconde Juromenha (AEVJ); Verify the relationship between participating in the ICA and the level of knowledge acquired from it. Methods: Behaviors and beliefs concerning alcohol consumption and knowledge about the repercussions of it in the human body, mainly regarding the liver, were assessed by questionnaire. The questionnaire was completed before and after the ICA, by the control group (CG) and the study group (SG), respectively. The answers concerning knowledge were given points, later converted to a score from 0 to 100%. Data was analyzed applying descriptive statistics and the t-student test using SPSS 20.0. Results: After statistical analysis, it was found an average score of 48.8% for SG and 46.2% for CG. The difference between groups was statistically significant only in AEPM where ICA included a practical methodology (microscopic and macroscopic observation of pork livers), contrary to AEVJ. Conclusions: BSc intervention through ICA’s improves teenagers’ knowledge. Theoretical knowledge associated with practical approaches improves the retention of information and the development of a conscious behavior about the consumption of alcohol.

How to reduce energy consumption on pultrusion

The global warming due to high CO2 emission in the last years has made energy saving a global problem nowadays. However, manufacturing processes such as pultrusion necessarily needs heat for curing the resin. Then, the only option available is to apply all efforts to make the process even more efficient. Different heating systems have been used on pultrusion, however, the most widely used are the planar resistances. The main objective of this study is to develop another heating system and compares it with the former one. Thermography was used in spite of define the temperature profile along the die. FEA (finite element analysis) allows to understand how many energy is spend with the initial heating system. After this first approach, changes were done on the die in order to test the new heating system and to check possible quality problems on the product. Thus, this work allows to conclude that with the new heating system a significant reduction in the setup time is now possible and an energy reduction of about 57% was achieved.

Optimization of the Pultrusion process

Manufacturing processes need permanently to innovate and optimize because any can be susceptible to continuous improvement. Innovation and commitment to the development of these new solutions resulting from existing expertise and the continuing need to increase productivity, flexibility and ensuring the necessary quality of the manufactured products. To increase flexibility, it is necessary to significantly reduce set-up times and lead time in order to ensure the delivery of products ever faster. This objective can be achieved through a normalization of the pultrusion line elements. Implicitly, there is an increase of productivity by this way. This work is intended to optimize the pultrusion process of structural profiles. We consider all elements of the system from the storehouse of the fibers (rack) to the pultrusion die. Particular attention was devoted to (a) the guidance system of the fibers and webs, (b) the resin container where the fibers are impregnated, (c) standard plates positioning of the fibers towards the entrance to the spinneret and also (d) reviewed the whole process of assembling and fixing the die as well as its the heating system. With the implementation of these new systems was achieved a significant saving of time set-up and were clearly reduced the unit costs of production. Quality assurance was also increased.

Acqusition and data analysis of the eco-efficiency for the establishment of indicators parameters for industrial environmental sustainability

The industrial activity is inevitably associated with a certain degradation of the environmental quality, because is not possible to guarantee that a manufacturing process can be totally innocuous. The eco-efficiency concept is globally accepted as a philosophy of entreprise management, that encourages the companies to become more competitive, innovative and environmentally responsible by promoting the link between its companies objectives for excellence and its objectives of environmental excellence issues. This link imposes the creation of an organizational methodology where the performance of the company is concordant with the sustainable development. The main propose of this project is to apply the concept of eco-efficiency to the particular case of the metallurgical and metal workshop industries through the development of the particular indicators needed and to produce a manual of procedures for implementation of the accurate solution.

Depósitos continentais e marinhos na plataforma litoral da região do Porto. Importância da tectónica na sua organização espacial

One of the most common characteristics of Portuguese littoral is the existence of a planed surface (the so-called "littoral platform"), situated at different altitudes and bordered from the inland by a straight relief, strongly contrasting with that planed surface. This one is generally covered with several outcrops of the so-called Plio-Pleistocene deposits. Till the eighties this platform has been interpreted as stable staircase of old marine levels, registering in a passive way the eustatic variations. The rigid step bordering it easterly should be a fossil cliff. However, our study has proved that many of these deposits have a continental origin. These continental deposits have fluvial or alluvial fan facies and they are lying above 40 meters. Marine deposits seem to be quite rare and they only occupy a small western area, beneath the altitude of 40 meters and developing into three different marine levels. There is a rigid step between the two kinds of deposits. We think that the clear geometric separation between these deposits together with this rigid step, indicates a tectonic origin. It seems that the sea must have touched only the western part of this surface, when neotectonic movements lowered it down. There are more evidences for neotectonic movements: a) there are faults (mainly inverse faults) affecting the higher deposits of this littoral platform; b) the same marine level seems to appear at different altitudes, developing an irregular pattern with a general trend dipping from the North to the South.

TERT Promoter Mutations Are a Major Indicator of Poor Outcome in Differentiated Thyroid Carcinomas

Context: Telomerase promoter mutations (TERT) were recently described in follicular cell-derived thyroid carcinomas (FCDTC) and seem to be more prevalent in aggressive cancers. Objectives: We aimed to evaluate the frequency of TERT promoter mutations in thyroid lesions and to investigate the prognostic significance of such mutations in a large cohort of patients with differentiated thyroid carcinomas (DTCs). Design: This was a retrospective observational study. Setting and Patients: We studied 647 tumors and tumor-like lesions. A total of 469 patients with FCDTC treated and followed in five university hospitals were included. Mean follow-up (±SD) was 7.8 ± 5.8 years. Main Outcome Measures: Predictive value of TERT promoter mutations for distant metastasization, disease persistence at the end of follow-up, and disease-specific mortality. Results: TERT promoter mutations were found in 7.5% of papillary carcinomas (PTCs), 17.1% of follicular carcinomas, 29.0% of poorly differentiated carcinomas, and 33.3% of anaplastic thyroid carcinomas. Patients with TERT-mutated tumors were older (P < .001) and had larger tumors (P = .002). In DTCs, TERT promoter mutations were significantly associated with distant metastases (P < .001) and higher stage (P < .001). Patients with DTC harboring TERT promoter mutations were submitted to more radioiodine treatments (P = .009) with higher cumulative dose (P = .004) and to more treatment modalities (P = .001). At the end of follow-up, patients with TERT-mutated DTCs were more prone to have persistent disease (P = .001). TERT promoter mutations were significantly associated with disease-specific mortality [in the whole FCDTC (P < .001)] in DTCs (P < .001), PTCs (P = .001), and follicular carcinomas (P < .001). After adjusting for age at diagnosis and gender, the hazard ratio was 10.35 (95% confidence interval 2.01–53.24; P = .005) in DTC and 23.81 (95% confidence interval 1.36–415.76; P = .03) in PTCs. Conclusions: TERT promoter mutations are an indicator of clinically aggressive tumors, being correlated with worse outcome and disease-specific mortality in DTC. TERT promoter mutations have an independent prognostic value in DTC and, notably, in PTC.

Comportamentos de sexo seguro em individuos infectados por VIH

A investigação científica que se seguiu à descoberta da infecção pelo vírus da imunodeficiência humana (VIH) representou um marco histórico importante, permitindo a instituição de terapêutica e alterando a história natural da infecção, melhorando as expectativas dos indivíduos infectados.Se, por um lado, a terapêutica antirretroviral de alta eficácia (do inglês, Highly Active Antiretroviral Theraphy: HAART), nos países desenvolvidos, teve um enorme impacto na melhoria da qualidade de vida e esperança média de vida dos indivíduos infectados, permitindo-lhes encarar a infecção como uma doença crónica, por outro lado, introduziu-se uma nova dinâmica epidemiológica na transmissão de VIH e um novo desafio para a sua prevenção.Os comportamentos sexuais são o factor-alvo através do qual se pode, de uma forma mais eficaz, prevenir a possibilidade de infectar um qualquer indivíduo na comunidade. Parece, pois, importante haver necessidade de um olhar atento da Saúde Pública sobre a vida sexual dos indivíduos infectados, não só na tentativa de, promover a sua qualidade de vida, como também, de prevenir a disseminação da doença, e, ainda mais importante, prevenir a disseminação do vírus nas suas formas resistentes.O objectivo deste estudo foi analisar a consistência do uso de preservativo/práticas de sexo seguro, em indivíduos infectados por VIH, seguidos em Consulta de Imunodepressão, do Serviço de Doenças Infecciosas, do Hospital de Santa Maria. Pretende-se avaliar, no âmbito da “Educação para a Saúde”, a necessidade de aconselhamento aos indivíduos infectados, relativamente aos seus comportamentos sexuais.Para o efeito, realizou-se um estudo descritivo e transversal. A população envolvida compreendeu todos os indivíduos infectados seguidos na Consulta de Imunodepressão. A amostra foi seleccionada através de aleatorização simples e constituída por 98 elementos. A colheita de dados foi efectuada através do método de entrevista, a qual só teve início após a assinatura do consentimento informado. O estudo decorreu entre 14 de Março e 27 de Junho de 2008.Foram analisados os dados relativamente às variáveis: sócio-demográficas, estado serológico da infecção, história sexual, consumo de substâncias, comportamento sexual e percepção de risco da transmissão da infecção por VIH.Os comportamentos de sexo não seguro foram associados ao número de parceiros sexuais/ano (p=0,007), ter parceiro sexual habitual (p=0,010), ter múltiplos parceiros sexuais ocasionais (p=0,000) e à prática de sexo oral (sexo oral receptivo, p=0,001; sexo oral activo, p=0,006).Os resultados demonstraram a importância da prevenção secundária nos indivíduos infectados por VIH. A necessidade dos centros de atendimento estarem providos de mensagem de prevenção, ensinos e aconselhamento a todas as pessoas infectadas e, também, aos seus parceiros sexuais, aumentando-lhes a qualidade de vida e reduzindo o risco de transmissão da infecção por HIV. ABSTRACT: The scientific research that followed the finding of human immunodeficiency virus (HIV) infection represented an important historical mark, allowing therapeutic institution and changing the natural history of the infection, thus improving the expectations of infected individuals. If by one side the Highly Active Antiretroviral Therapy (HAART) had an enormous impact on the improvement of life quality and life expectancy of the infected individuals on the developed countries, allowing them to face the infection as a chronic disease, on the other side it was introduced a epidemiologic dynamic on the HIV transmission and a new challenge for its prevention. Sexual behaviour is the main factor through which is possible to prevent more efficiently the possibility of infection of a community’s individual. Thus it appears important the need of Public Health to have a careful look into the sexual life of infected individuals, not only to try to promote their life quality but as well to prevent the dissemination of the disease and more importantly prevent the dissemination of the virus in its resistant forms. The objective of this study was to analyse the consistency of the use of condoms/safe sex by individuals infected by HIV that are followed by the Infectious Disease Service of the Santa Maria Hospital through Immune-depression Appointments. The goal was to evaluate the need of advisement to the infected individuals relatively to their sexual behaviours. For that it was done a descriptive and transversal study. The involved population included all infected individuals followed in the Immune-depression Appointments. The sample was selected by simple randomisation and was composed by 98 elements. The data was obtained by interview method, which was initiated after signing the informed consent. The study was took place between 14 March and 27 June 2008. It was analysed the data relative to the variables: socio-demographics, serologic state of the infection, sexual history, substances consumption, sexual behaviour and risk perception on the transmission of HIV infection. The unsafe sexual behaviours were associated to the number of sexual partners/year (p=0,007), having steady partner (p= 0,010), having occasional sexual partners (p=0,000) and oral sex practice (receptive oral sex, p=0,001; active oral sex, p= 0,006).The results demonstrated the importance of the secondary prevention on individuals infected by HIV. It also demonstrated the need of providing the attendance centres with a prevention message, teachings and advises to all infected persons as well as to their sexual partners, increasing their life quality and reducing the transmission risk of HIV infection.
