Massa corporal e aptidão física dos militares da Marinha Portuguesa : distribuição e tendências segundo os indicadores, prevalência e possíveis consequências do excesso de peso

RESUMO - O excesso de peso (EP) é um dos mais graves problemas de Saúde Pública deste século XXI, dada a sua elevada e crescente prevalência a nível mundial, afectando um elevado número de adultos, adolescentes e crianças, com graves consequências na saúde, sendo responsável pelo aumento das doenças crónicas e pela diminuição da duração e qualidade de vida dos indivíduos. Em Portugal, a prevalência do EP afecta mais de metade da população adulta portuguesa. No meio militar, este problema é reflexo da prevalência do EP na população em geral e, para além das consequências económicas e na saúde, prejudica a aparência militar e pode comprometer a aptidão física. Pretende-se com realizar um estudo exploratório, com vista a realizar uma primeira abordagem do conhecimento do perfil e tendências do índice de massa corporal (IMC), bem como da prevalência do EP e, ainda, de possíveis associações entre o EP e a aptidão física, numa amostra representativa de militares no activo da Marinha Portuguesa (MP). Com os resultados deste estudo pretende-se alertar, pela primeira vez, para a problemática do EP no meio militar, contribuindo também para ampliar o conhecimento da prevalência do EP em subgrupos da população nacional. Os resultados obtidos poderão servir de base para a constituição de um sistema de vigilância, para um correcto entendimento da evolução da tendência do IMC e da prevalência de EP dos militares da MP, bem como disponibilizar uma base de partida para outros estudos, focando os determinantes do EP associados a estilos de vida. ------------ABSTRACT - Overweight and obesity severe Public Health problems of the XXI Century due to its high and increasing worldwide prevalence, including Portugal, and it afects a high number of adults, adolescents and children, with serious health consequences, being responsible for the increase of chronic diseases and for lower life quality and lower life expectancy. In Portugal, overweight prevalence affects more than half of adult’s population. Among the Navy, overweight problem reflects population’s tendency, and, besides it’s economic and health consequences, can affect military image and can jeopardize physical fitness with consequences in the Navy response and performance. This study carries out an exploratory first approach of body’s mass index profile and trends, as well the prevalence of overweight in a representative sample of on duty Portuguese Navy staff, and the potential links between overweight and physical fitness among this population. It outcome seeks, for the first time, to draw attention to the overweight problematic among Navy staff, being also a way to enhance the knowledge of overweight prevalence among population sub-groups. It outcome can be a starting point for the set up of monitoring systems, for a correct understanding body’s mass index evolution trends and the prevalence Navy staff overweight, being also a foundation for other studies, foc

Virulence profile of ten Paracoccidioides brasiliensis isolates: association with morphologic and genetic patterns

Ten isolates of Paracoccidioides brasiliensis were examined for differences in virulence in outbred mice intravenously inoculated with the fungus, associated with mycelial morphology, and genetic patterns measured by random amplified polymorphic DNA (RAPD). Virulence was evaluated by viable yeast cell recovery from lungs and demonstration of histopathologic lesions in different organs. The results showed that the isolates presented four virulence degrees: high virulence, intermediate, low and non-virulence. RAPD clustered the isolates studied in two main groups with 56% of genetic similarity. Strains with low virulence, Pb265 or the non-virulent, Pb192, showed glabrous/cerebriform morphology and high genetic similarity (98.7%) when compared to the other isolates studied. The same was observed with Bt79 and Bt83 that shared 96% genetic similarity, cottony colonies and high virulence. The RAPD technique could only discriminate P. brasiliensis isolates according to glabrous/cerebriform or cottony colonies, and also high from low virulence strains. Isolates with intermediate virulence such as Pb18, Pb18B6, Bt32 and Bt56 showed variability in their similarity coefficient suggesting that RAPD was able to detect genetic variability in this fungal specie. Virulence profile of P. brasiliensis demonstrated that both mycelial morphologic extreme phenotypes may be associated with fungal virulence and their in vitro subculture time. Thus, RAPD technique analysis employed in association with virulence, morphologic and immunologic aspects might prove adequate to detect differences between P. brasiliensis isolates.

Differences in internet and LMS usage: a case study in higher education

The Internet plays an important role in higher education institutions where Learning Management Systems (LMS) occupies a main role in the eLearning realm. In this chapter we aim to characterize the Internet and LMS usage patterns and their role in the largest Portuguese Polytechnic Institute. The usage patterns were analyzed in two components: characterization of Internet usage and the role of Internet and LMS in education. Using a quantitative approach, the data analysis describes the differences between gender, age and scientific fields. The carried qualitative analysis allows a better understanding of students’ both motivations, opinions and suggestions of improvement. The outcome of this work is the presentation of the Portuguese students’ profile regarding Internet and LMS usage patterns. We expect that these results can be used to select the most suitable digital pedagogical processes and tools to be adopted regarding the learning process and most adequate LMS’s policies.

The Spectrum of Mutations and Molecular Pathogenesis of Hemophilia A in 181 Portuguese Patients

Disease-causing alterations within the F8 gene were identified in 177 hemophilia A families of Portuguese origin. The spectrum of non-inversion F8 mutations in 101 families included 67 different alterations, namely: 36 missense, 8 nonsense and 4 splice site mutations, as well as 19 insertions/deletions. Thirty-four of these mutations are novel. Molecular modeling allowed prediction of the conformational changes introduced by selected amino acid substitutions and their correlation with the patients' phenotypes. The relatively frequent, population-specific, missense mutations together with de novo alterations can lead to significant differences in the spectrum of F8 mutations among different populations.

Determining the receptivity to the bluetooth marketing by the portuguese consumer

With increasing technological innovation, the concept of marketing and its applications become more functional and wide. Today, we witness a steady growth in the development of mobile marketing campaigns, i.e., marketing campaigns targeting mobile devices (mobile phones, Smartphones, PDAs, tablets). Among the several mobile technologies available (Bluetooth networks, Wi-Fi, WAP, SMS service, MMS), Bluetooth seems to have the biggest potential for the least invasive consumer mobile marketing strategy. This study seeks to answer the question "what factors may motivate the Portuguese consumer to accept Bluetooth marketing?.“ We propose a conceptual model capable of investigating the relationships between the several responsiveness factors to Bluetooth marketing. The development of a set of hypotheses supported by an online questionnaire to a valid sample of 755 participants, demonstrates that there is a relationship between factors such as expanded knowledge of the technology, and Bluetooth marketing receptivity. Additionally, we find that the information value of mobile advertising messages, such as entertainment value and personalization, relates well to responsiveness. The ability to accept/dismiss promotional messages sent to mobile phones and other safety features also correlated well with Bluetooth marketing receptivity.

Power indices applied to Portuguese Parliament

In this paper, we apply the following four power indices to the Portuguese Parliament: Shapley–Shubik index, Banzhaf index, Deegan–Packel index and Public Good Index. We also present the main notions related with simple games and discuss the features of each power index by means of their axiomatic characterizations.

Primary Antiphospholipid Syndrome: Pregnancy Outcome in a Portuguese Population

Introduction:Women with antiphospholipid syndrome(APS) may suffer from recurrent miscarriage, fetal death, fetal growth restriction (FGR), pre-eclampsia, placental abruption, premature delivery and thrombosis. Treatment with aspirin and low molecular weight heparin (LMWH) combined with close maternal-fetal surveillance can change these outcomes. Objective: To assess maternal and perinatal outcome in a cohort of Portuguese women with primary APS. Patients and Methods: A retrospective analysis of 51 women with primary APS followed in our institution (January 1994 to December 2007). Forty one(80.4%) had past pregnancy morbidity and 35.3%(n=18) suffered previous thrombotic events. In their past they had a total of 116 pregnancies of which only 13.79 % resulted in live births. Forty four patients had positive anticardiolipin antibodies and 33 lupus anticoagulant. All women received treatment with low dose aspirin and LMWH. Results: There were a total of 67 gestations (66 single and one multiple). The live birth rate was 85.1%(57/67) with 10 pregnancy failures: seven in the first and second trimesters, one late fetal death and two medical terminations of pregnancy (one APS related). Mean (± SD) birth weight was 2837 ± 812 g and mean gestational age 37 ± 3.3 weeks. There were nine cases of FGR and 13 hypertensive complications(4 HELLP syndromes). 54.4% of the patients delivered by caesarean section. Conclusions: In our cohort, early treatment with aspirin and LMWH combined with close maternal-fetal surveillance was associated with a very high chance of a live newborn.

Ambivalent Islam: the identity construction of Muslims under Portuguese colonial rule

This article wishes to contribute to the study of the historical processes that have been spotting Muslim populations as favourite targets for political analysis and governance. Focusing on the Portuguese archives, civil as well as military, the article tries to uncover the most conspicuous identity representations (mainly negative or ambivalent) that members of Portuguese colonial apparatus built around Muslim communities living in African colonies, particularly in Guinea-Bissau and Mozambique. The paper shows how these culturally and politically constructed images were related to the more general strategies by which Portuguese imagined their own national identity, both as ‘European’ and as ‘coloniser’ or ‘imperial people’. The basic assumption of this article is that policies enforced in a context of inter-ethnic and religious competition are better understood when linked to the identity strategies inherent to them. These are conceived as strategic constructions aimed at the preservation, the protection and the imaginary expansion of the subject, who looks for groups to be included in and out-groups to reject, exclude, aggress or eliminate. We think that most of the inter-ethnic relationships and conflicts, as well as the very experience of ethnicity, are born from this identity matrix.
