The first confirmed case of Diphyllobothrium latum in Brazil

Diphyllobothriasis is an infection of the small intestine by the broad tapeworm Diphyllobothrium sp. The associated symptomatology is nonspecific, but megaloblastic anemia is a well-described complication. Although the infection is common in temperate regions, descriptions in South America have so far been limited to Chile, Peru, and a few cases in Argentina. This paper presents the first confirmed Brazilian case of diphyllobothriasis. A 29-years-old woman living in Salvador (state of Bahia) apparently acquired the infection from eating sushi. The diagnosis was based on fecal examination that revealed a large quantity of operculated eggs. A single dose of praziquantel (600 mg) was sufficient to cure the infection.

Application by Waterford Institute of Technology for Designation as a University (Port Report)

This report provides our advice to the Minister for Education and Science on the application for designation as a university made by Waterford Institute of Technology (WIT). WIT submitted an application for designation in February 2006. There is a statutory procedure for the creation of a new university under Section 9 of the Universities Act 1997. We were asked to advise the Minister on the merits of the submission in order for her to provide guidance to Government on whether such a formal statutory review should be initiated. It is not a straightforward task to advise on this case for several reasons. These include the facts that: the regulatory environment for Institutes of Technology has changed significantly since WIT made their application; and the designation of any IoT would potentially challenge the government’s current higher education policy. So our report has to range more widely than the merits of the WIT application, taken at face value.

Toxoplasma gondii in animals used for human consumption

Food-borne toxoplasmosis in humans may result from exposure to different stages of Toxoplasma gondii, in particular from the ingestion of tissue cysts or tachyzoites contained in meat, primary offal (viscera) or meat-derived products of many different animals, or the ingestion of sporulated oocysts that are contained in the environment and may contaminate food and water. Although the potential for transmission of the parasite to humans via food has been known for several decades, it is not known which routes are most important from a public health point of view. It is likely that transmission of the parasite to humans is influenced not only by the potential contamination of various food sources, but also by the individual behaviour of consumers in different ethnic groups and geographical regions. Most current methods for detection of T. gondii in meat-producing animals, in products of animal origin, or in the environment are insufficient because they do not allow quantification of infectious stages. Hence, most studies report only qualitative data from which it is difficult to assess the true risk of infection in individual cases. There is a need for quantitative data so that efficient strategies to reduce food-borne transmission of T. gondii to humans can be developed.

Interpretation of wind components as compositional variables

The classical statistical study of the wind speed in the atmospheric surface layer is madegenerally from the analysis of the three habitual components that perform the wind data,that is, the component W-E, the component S-N and the vertical component,considering these components independent.When the goal of the study of these data is the Aeolian energy, so is when wind isstudied from an energetic point of view and the squares of wind components can beconsidered as compositional variables. To do so, each component has to be divided bythe module of the corresponding vector.In this work the theoretical analysis of the components of the wind as compositionaldata is presented and also the conclusions that can be obtained from the point of view ofthe practical applications as well as those that can be derived from the application ofthis technique in different conditions of weather

Relación entre la edad, el índice de masa corporal, el grado de dependencia y la calidad de vida en pacientes con desnutrición tras un alta hospitalaria.

Introduction: The quality of life assessment means investigating how patients perceive their disease. Malnutrition-specific characteristics make patients more vulnerable, so it is important to know how these factors impaction patients’ daily life. Aim: To assess the quality of life in malnourished patients who have had hospital admission, and to determine the relationship of the quality of life with age, body mass index, diagnosis of malnutrition, and dependency. Method: Multicenter transversal descriptive study in 106 malnourished patients after hospital admission. The quality of life (SF-12 questionnaire), BMI, functional independency (Barthel index), morbidity, and a dietary intake evaluation were assessed. The relationship between variables was tested by using the Spearman correlation coefficient Results: The patients of the present study showed a SF-12 mean of 38.32 points. The age was significantly correlated with the SF-12 (r= -0.320, p= 0.001). The BMI was correlated with the SF-12 (r= 0.251, p= 0.011) and its mental component (r= 0.289, p= 0.03). It was also reported a significant correlation between the Barthel index and the SF-12 (r= 0.370, p< 0.001). Conclusions: The general health perception in malnourished patients who have had a hospital admission was lower than the Spanish mean. Moreover, the quality of life in these patients is significantly correlated with age, BMI and functional independency.

Religion/Spirituality and dissociative disorders

Although medicine is practised in a secular setting, religious and spiritual issues have an impact on patient perspectives regarding their health and the management of any disorders that may afflict them. This is especially true in psychiatry, as feelings of spirituality and religiousness are very prevalent among the mentally ill. Clinicians are rarely aware of the importance of religion and understand little of its value as a mediating force for coping with mental illness. This book addresses various issues concerning mental illness in psychiatry: the relation of religious issues to mental health; the tension between a theoretical approach to problems and psychiatric approaches; the importance of addressing these varying approaches in patient care and how to do so; and differing ways to approach Christian, Muslim, and Buddhist patients. This is the first book to specifically cover the impact of religion and spirituality on mental illness.

Decoding sequence learning from single-trial intracranial EEG in humans.

We propose and validate a multivariate classification algorithm for characterizing changes in human intracranial electroencephalographic data (iEEG) after learning motor sequences. The algorithm is based on a Hidden Markov Model (HMM) that captures spatio-temporal properties of the iEEG at the level of single trials. Continuous intracranial iEEG was acquired during two sessions (one before and one after a night of sleep) in two patients with depth electrodes implanted in several brain areas. They performed a visuomotor sequence (serial reaction time task, SRTT) using the fingers of their non-dominant hand. Our results show that the decoding algorithm correctly classified single iEEG trials from the trained sequence as belonging to either the initial training phase (day 1, before sleep) or a later consolidated phase (day 2, after sleep), whereas it failed to do so for trials belonging to a control condition (pseudo-random sequence). Accurate single-trial classification was achieved by taking advantage of the distributed pattern of neural activity. However, across all the contacts the hippocampus contributed most significantly to the classification accuracy for both patients, and one fronto-striatal contact for one patient. Together, these human intracranial findings demonstrate that a multivariate decoding approach can detect learning-related changes at the level of single-trial iEEG. Because it allows an unbiased identification of brain sites contributing to a behavioral effect (or experimental condition) at the level of single subject, this approach could be usefully applied to assess the neural correlates of other complex cognitive functions in patients implanted with multiple electrodes.

Stages of change, barriers, benefits, and preferences for exercise in RA patients: a cross-sectional study

OBJECTIVES: To determine the distribution of exercise stages of change in a rheumatoid arthritis (RA) cohort, and to examine patients' perceptions of exercise benefits, barriers, and their preferences for exercise. METHODS: One hundred and twenty RA patients who attended the Rheumatology Unit of a University Hospital were asked to participate in the study. Those who agreed were administered a questionnaire to determine their exercise stage of change, their perceived benefits and barriers to exercise, and their preferences for various features of exercise. RESULTS: Eighty-nine (74%) patients were finally included in the analyses. Their mean age was 58.4 years, mean RA duration 10.1 years, and mean disease activity score 2.8. The distribution of exercise stages of change was as follows: precontemplation (n = 30, 34%), contemplation (n = 11, 13%), preparation (n = 5, 6%), action (n = 2, 2%), and maintenance (n = 39, 45%). Compared to patients in the maintenance stage of change, precontemplators exhibited different demographic and functional characteristics and reported less exercise benefits and more barriers to exercise. Most participants preferred exercising alone (40%), at home (29%), at a moderate intensity (64%), with advice provided by a rheumatologist (34%) or a specialist in exercise and RA (34%). Walking was by far the preferred type of exercise, in both the summer (86%) and the winter (51%). CONCLUSIONS: Our cohort of patients with RA was essentially distributed across the precontemplation and maintenance exercise stages of change. These subgroups of patients exhibit psychological and functional differences that make their needs different in terms of exercise counselling.

Identity formation in social networks websites: facebook and the interaction between young individuals in the cases of Slovenia and Catalonia

This paper lays down some theoretical framework for further research to be made on the subject of how identity of young Slovenian and Catalan users is forming within the social networking website Facebook. The author pursues his interest based on observation of how communicationand thus interaction between users is changing and how this is reflected in everyday practices. In so doing he tries to identify the connections between the individual, society and technology, asthese are more and more interwoven, and we cannot think one without the other in thecontemporary globalised world.

Problemas entomológicos na cultura do tomate em Cabo Verde. Estudo de caso na Ilha de Santiago

O tomate (Lycopersicon esculentum) é uma das principais hortícolas produzidas na Ilha de Santiago, Cabo Verde. Com o objectivo de se identificar as principais pragas associadas a esta cultura e de se acompanhar a evolução ao longo do ciclo fenológico, instalaram-se parcelas experimentais em São Jorge dos Órgãos, São Domingos e Tarrafal. No presente trabalho caracterizou-se a agricultura cabo-verdiana e ilustrou-se a importância do sector hortícola na agricultura. Descreveu-se sucintamente a cultura do tomate e as variedades utilizadas. Apresentou-se uma revisão bibliográfica para as pragas referenciadas neste país e para as potenciais, incidindo-se principalmente nos meios de protecção. Para a concretização dos objectivos propostos realizaram-se amostragens semanais nas parcelas instaladas. Identificaram-se algumas espécies anteriormente referenciadas como pragas e outras que foram observadas a infestar a cultura: Aphis sp., Brachycaudus sp., cicadelídeo, Megalurothrips sp. e Tuta absoluta. Acompanhou-se a evolução da incidência e da população de tripes, mosquinhas-brancas, lagartas, minas de larvas mineiras, afídeos e mirídeos no período de observação e analisou-se a sua distribuição vertical na planta. Identificou-se Tuta absoluta em campos de agricultores e avaliaram-se os estragos provocados por esta praga, através da realização de inquéritos por questionário aos agricultores afectados.

Dinâmica da população do concelho de Tarrafal entre 1990 e 2000 e o seu impacto socio-económico

O presente trabalho, cujo o tema é «Dinâmica da população do concelho de Tarrafal entre 1990 e 2000 e o seu impacto socio-económico», vem na sequência de investigação para apresentação de um trabalho científico de fim do curso como requisito parcial para a obtenção do grau de licenciatura em Geografia. Este trabalho surgiu, igualmente, da verificação de vários problemas que afectam o concelho, tanto de ordem demográfico, económico, social como ambiental. Não obstante os problemas, que se arrastam desde há muito tempo e que levou na, actualidade, ao posicionamento do concelho de entre os mais pobres do arquipélago de Cabo Verde. O concelho tem vindo a aumentar consideravelmente o seu efectivo populacional ao longo dos tempos. Ao longo da elaboração deste trabalho enfrentamos algumas dificuldades, sobretudo na aquisição de dados, devido à criação do concelho de São Miguel em 1997, que veio separar a freguesia de São Miguel Arcanjo da freguesia da de Santo Amaro Abade, dando assim origem a dois concelhos autónomos. Por isso no segundo capítulo, onde analisamos dinâmica/estado e evolução demográfica enfrentamos algumas dificuldades, dado à ausência de séries estatísticas específicas sobre o actual concelho em estudo. Neste contexto optamos pela análise conjunta (Tarrafal e São Miguel) de alguns indicadores. Como sabemos, a dinâmica de uma população tem implicações directas nas condições sócio-económicas, podendo arrastar consigo alguns problemas que podem influir nas condições de vida das populações. Sendo assim, com estes propósitos procurámos fazer uma abordagem geral sobre a dinâmica da população no concelho do Tarrafal e o seu impacto sócio-económico, em vários ângulos, nomeadamente: os aspectos sócio-culturais, económicos e demográficos. Além da introdução onde procurámos fazer o enquadramento do trabalho, com os objectivos preconizados, a metodologia seguida, a justificação da importância do tema, este trabalho se encontra estruturado em quatro capítulos, mais as conclusões, recomendações, bibliografias e anexos.

How accurate is the current picture of human genetic variation?

Our understanding of the distribution of worldwide human genomic diversity has greatly increased over recent years thanks to the availability of large data sets derived from short tandem repeats (STRs), insertion deletion polymorphisms (indels) and single nucleotide polymorphisms (SNPs). A concern, however, is that the current picture of worldwide human genomic diversity may be inaccurate because of biases in the selection process of genetic markers (so-called 'ascertainment bias'). To evaluate this problem, we first compared the distribution of genomic diversity between these three types of genetic markers in the populations from the HGDP-CEPH panel for evidence of bias or incongruities. In a second step, using a very relaxed set of criteria to prevent the intrusion of bias, we developed a new set of unbiased STR markers and compared the results against those from available panels. Contrarily to recent claims, our results show that the STR markers suffer from no discernible bias, and can thus be used as a baseline reference for human genetic diversity and population differentiation. The bias on SNPs is moderate compared to that on the set of indels analysed, which we recommend should be avoided for work describing the distribution of human genetic diversity or making inference on human settlement history.

Turismo Rural na Ilha de Santo Antão como factor de Desenvolvimento das Aldeias de Fontaínhas, Corvo e Formiguinhas

Santo Antão é uma ilha onde a oferta turística passa pelo turismo de natureza, e pretendese criar um projecto ligado ao Turismo Rural nas aldeias de Fontaínhas, Corvo e Formiguinhas. As aldeias são rurais e enfrentam vários constrangimentos e é necessário implementar um leque de infra-estruturas como alojamento, estradas, postos de saúde, saneamento para o suporto do Turismo e optar por uma alternativa do desenvolvimento local. O objectivo é criar uma proposta de desenvolvimento do Turismo Rural que seja viável para estas aldeias. Numa segunda fase pretende-se também envolver as famílias rurais no desenvolvimento do turismo. As aldeias em questão reúnem condições naturais para o Turismo Rural, mas pretende apostar na valorização cultura, história e nos produtos locais. Having in mind that Santo Antão is an island where the offer is almost mandatory for nature tourism, it intends to develop a project connected to the Rural Tourism in the following villages of “Fontaínhas,” “Corvo” and “Formiguinhas”. These villages are rural and face various constraints, so it is necessary to implement a range of infrastructures to support Tourism and opt for an alternative that promotes local development. The aim is to create a model of development of Rural Tourism practicable to these villages. We also intend to involve local families in rural tourism development. The villages in question have natural conditions for Rural Tourism, but we want to focus on enhancing products like cultural and historical sites.

Serra Malagueta (Santiago de Cabo Verde): Estratégias de Conservação e Valorização do Património.

Com esta dissertação, pretende – se, em primeiro lugar, dar a conhecer Serra Malagueta enquanto Parque Natural, um meio geográfico cujo área de dois mil e seiscentos hectares e uma altitude de cerca de mil metros, tendo na sua dependência 579 habitantes, sendo, 290 masculinos e 289 femininas repartidas, aproximadamente, em 74 agregados e abarcando parte de três concelhos: Santa Catarina, Tarrafal e São Miguel, sendo este último de maior abrangência. Trata-se de uma área que apresenta uma enorme biodiversidade, mas também possui um património cultural, material e imaterial, de relevo. É neste tipo de regiões que se coloca a premência e necessidade de uma relação sustentável entre o homem, o ambiente e o património. Além de observar as características patrimoniais da região, importa perceber as dificuldades que se levantam a sua preservação e conservação, pelo que se destacam os fatores ou conjunto de fatores que estão intimamente ligados aos jogos de interesses, vários, e que a preservação e conservação desse património dependem da harmonização da tríade ambiente/natureza, a sociedade e o económico. Finalmente, impõe-se a análise das questões relativas à valorização do Parque, a sua preservação e conservação numa perspetiva de integração ambiental, social e económico sustentável, estribadas num conjunto de estratégias e que poderão ajudar a gerir conflitos, garantindo, também, a valorização de Serra Malagueta enquanto Património.

Unobserved heterogeneity and censoring in the demand for health care

This paper analyses the demand for private health care by Spanishhouseholds using a micro budget survey. The methodology used takescare of the three part decision process involved in this type ofbehaviour, namely the decision to use private health care, howoften to do so and how much to spend each time and also the effectsof unobserved heterogeneity. Since the theoretical frameworkcorresponds to the Grossman model of health investment, the resultsalso provide a test of the theory when these issues are considered.Finally, the obtained evidence also suggest that the current systemof tax deductions for private health care expenditures is regressive.
