Discursos e práticas na formação de profissionais fisioterapeutas: a realidade dos cursos de fisioterapia na região nordeste do Brasil

This study had a multidisciplinary focus, investigating the areas of health and education, and proposes to discuss the formation of health professionals, requiring their understanding of the factors involved in the production of knowledge, given that this formation has an impact on the quality of human and social life. The aim of this work was to investigate the relationship existing between the process of physical therapist formation and the practical activities developed during the undergraduate course in the Northeast of Brazil. This is an exploratory descriptive study with qualitative significance. The sample consisted of 73 subjects (33 professors and 40 students) from 6 physical therapy courses at different institutions in the Northeast of Brazil. Data collection was conducted through focus group interviews. In addition, we used a school assessment instrument from the health area. The data, analyzed using dialectical hermeneutics, showed that the Northeast of Brazil has the second largest number of physical therapy courses in the country, with 93 (11 public and 82 private) out of a total of 510. These numbers represent a growth of 1062.5% since 1991. The pedagogical projects are guided by National Curricular Directives as well as by the country s health system. The prevalent pedagogy is that of transmission, and the contents/disciplines are generally not integrated with practice, a situation that hinders the integrality and interdisciplinarity of health care. It can be concluded that there is a need for implementing integrated curricula and for better qualified professors to effectively put this process into practice

Estimativas de mortalidade para a região nordeste do Brasil em 2010: uma associação do método demográfico equação geral de balanceamento, com o estimador bayesiano empírico

One of the greatest challenges of demography, nowadays, is to obtain estimates of mortality, in a consistent manner, mainly in small areas. The lack of this information, hinders public health actions and leads to impairment of quality of classification of deaths, generating concern on the part of demographers and epidemiologists in obtaining reliable statistics of mortality in the country. In this context, the objective of this work is to obtain estimates of deaths adjustment factors for correction of adult mortality, by States, meso-regions and age groups in the northeastern region, in 2010. The proposal is based on two lines of observation: a demographic one and a statistical one, considering also two areas of coverage in the States of the Northeast region, the meso-regions, as larger areas and counties, as small areas. The methodological principle is to use the General Equation and Balancing demographic method or General Growth Balance to correct the observed deaths, in larger areas (meso-regions) of the states, since they are less prone to breakage of methodological assumptions. In the sequence, it will be applied the statistical empirical Bayesian estimator method, considering as sum of deaths in the meso-regions, the death value corrected by the demographic method, and as reference of observation of smaller area, the observed deaths in small areas (counties). As results of this combination, a smoothing effect on the degree of coverage of deaths is obtained, due to the association with the empirical Bayesian Estimator, and the possibility of evaluating the degree of coverage of deaths by age groups at counties, meso-regions and states levels, with the advantage of estimete adjustment factors, according to the desired level of aggregation. The results grouped by State, point to a significant improvement of the degree of coverage of deaths, according to the combination of the methods with values above 80%. Alagoas (0.88), Bahia (0.90), Ceará (0.90), Maranhão (0.84), Paraíba (0.88), Pernambuco (0.93), Piauí (0.85), Rio Grande do Norte (0.89) and Sergipe (0.92). Advances in the control of the registry information in the health system, linked to improvements in socioeconomic conditions and urbanization of the counties, in the last decade, provided a better quality of information registry of deaths in small areas

Caracterização in situ e diversidade genética de algodoeiros mocós (Gossypium hissutum raça marie galante) da Região Nordeste do Brasil

Brazil is one of the major centers of diversity for polyploid cotton plants; these plants belong to the genus Gossypium, which has three known species: G. hirsutum, G. barbadense and G. mustelinum. The Northeast is the only region where the three species occur, the last group being endemic. Northeast s cotton plants can be important sources of variability for genetic breeding. It is believed that great part of local diversity is being lost, due to economic, political, cultural and agricultural problems. In an attempt to mitigate this loss and delineate conservation strategies it is necessary to know how the species are found where they occur. The objective was to characterize and determine how plants are maintained in situ in the states of Maranhão, Piauí, Ceará, Rio Grande do Norte and Paraíba at the beginning of the XXI century. The in situ characterization of G. hirsutum and G. barbadense was conducted through structured interviews with the cotton plants owners and through the analysis of the environment. The data were collected during expeditions undertaken between the years 2004 to 2005. Twenty-two plants were collected in the state of Paraíba, forty-four in the state of Rio Grande do Norte, one hundred and forty-six in the state of Ceará, forty in the state of Maranhão and ninety-one plants in the state of Piauí. All plants collected in the states of Paraíba and Rio Grande do Norte belonged to moco type. Moco cotton plants also predominated in the other states, representing 92%, 62% and 78% of plants collected in Ceará, Piauí and Maranhão, respectively. The other cotton plants collected belong to the species G. barbadense. The cotton plants were found in situ as dooryard plants, roads side, feral populations, cultivation or local varieties. Great part were dooryard plants (45.2%), being major in Piauí and Maranhão. Cultivation predominated in Ceará; in Rio Grande do Norte feral populations were the most frequent and, in Paraíba, local varieties. The maintenance of moco plants is related, mainly, to the phytotherapic domestic use (20.9%) and to confection of lamp wicks (29.7%). Few inhabitants in Paraíba, Rio Grande do Norte, Piauí and none in Maranhão used harvest the plants, storage the seeds or gin; however, in Ceará, 40.5% of owners affirmed that they harvested and commercialized the fiber. It was found that the maintenance of species is dependent of the fragile cultural habits of local inhabitants, therefore the maintenance in situ is not a suitable way to conservation of genetic resources. The efforts must be directed to the continuity of collections, maintenance and characterization ex situ

Comportamento e ecologia acústica da baleia jubarte (Megaptera novaeangliae) na região Nordeste do Brasil

The acoustic ecology concept involve the relation between the live organisms and their sound environment and is applied in the present work to study the context in which the humpback whale (Megaptera novaeangliae) singing behavior, known as the most complex display in the nature, occurred in the northeastern Brazilian coast, outside the core area of Abrolhos Bank, between 2005 and 2010.I analyze the singer male occurrence , their spatial distribution and probable relations with oceanographic features, such as depth, tide regimen and moon phases. I also describe the acoustic structure and temporal variation of the singing behavior, based on song frequency and time measurements outside the Abrolhos Bank, and further compare the song complexity, registered in the same period, between Abrolhos Bank (16°- 19° S, 37°- 39° W) and the adjacent North Coast, herein considered from Itacaré (14° S, 38° W) to Aracaju (11° S, 37° W). Additionally, I look for describe and analyze anthropogenic noise sources in the marine environment of the study area, produced by the oil industry as well as by the whale watching operation, relating their frequencies to the acoustic niche utilized by the humpbacks. The results indicated a great plasticity in the singing behavior, evidenced by the occurrence of singer males in diverse social structures, from solitary individuals to other groups, even containing females and calves, as well as by the diversity which compound the song, when compared between two regions inside the same breeding area, which present distinct oceanographic characteristics. The singer male distribution may be related with the continental shelf extent along the study area. The anthropogenic noise presented frequency range, amplitude and sound intensity in potential to interfere acoustically in the singing behavior of the species, may resulting in disturbance during the breeding season in the Brazilian coast. Implications about the obtained results in the humpback whale mating system are discussed. In this way, I pretend to contribute with the acoustic ecology subject and provide information to subsidize humpback whale conservation

Atividade pozolânica de arenito zeolítico da região Nordeste do Brasil

No nordeste do Brasil, existe a ocorrência de zeolitas sedimentares relacionadas a arenitos, descoberta nos anos 2000. Esses arenitos são constituídos de quartzo, zeolitas naturais (estilbita) e argilominerais (esmectita). Estudos preliminares constataram que esse arenito pode ser empregado como material pozolânico em sistemas à base de cimento Portland, desde que o material seja peneirado para remoção do quartzo e ativado termicamente, uma vez que a estilbita é zeolita de baixa atividade pozolânica. O objetivo geral desse trabalho foi determinar qual a fração granulométrica que proporciona a maior concentração de zeolita e esmectita e a temperatura de calcinação que acarreta a maior atividade pozolânica. No programa experimental, empregou-se o arenito zeolítico passante nas peneiras #200 e #325 e calcinado às temperaturas de 150ºC, 300ºC e 500ºC. A análise da caracterização mineralógica das amostras peneiradas foi realizada por difração de raios X, por análises termogravimétrica e termodiferencial. Para avaliação da reatividade, foram realizados ensaios mecânicos de atividade pozolânica em argamassas de cal hidratada e cimento Porltand. Os resultados mostraram que a amostra peneirada na peneira #200 foi a mais adequada porque apresentou elevada concentração de estilbita e um percentual maior de material passante em comparação a amostra da peneira #325, 15% e 2% respectivamente. A temperatura de calcinação de 500ºC foi a que proporcionou a maior atividade pozolânica, em razão da modificação mais efetiva da estrutura cristalina, tanto da estilbita, como da esmectita. As temperaturas mais moderadas a 150ºC e 300ºC não foram suficientes para a obtenção dos mesmos resultados. As argamassas com o arenito passante na peneira #200 e calcinado a 500ºC atingiram os valores limites mínimos exigidos para que um material seja considerado pozolânico, no caso, 6 MPa para argamassas de cal hidratada e 75% para o índice de atividade pozolânica (IAP).

Avaliação preliminar do emprego de arenito zeolítico da região nordeste do Brasil como material pozolânico para cimento Portland

As zeolitas possuem atividade pozolânica normalmente sem a necessidade de ativação térmica, por isto têm sido empregadas na produção de cimento e concreto hidráulicos desde a época do império romano. Hoje em dia são utilizadas na fabricação do cimento Portland através da substituição do clinquer em percentuais que variam entre 5 e 20%, dependendo da reatividade e da finura da zeólita. Em razão disto, são muito importantes do ponto de vista econômico e ambiental, principalmente quando não necessitam de tratamento térmico para adquirirem caráter pozolânico satisfatório, porque reduzem significativamente a energia de produção do clinquer e a liberação de CO₂ proveniente tanto da descarbonatação da calcita como da combustão de combustíveis fósseis. Contudo, dados sobre reservas de zeólitas naturais são escassos e imprecisos. No Brasil, não existe conhecimento sobre depósitos naturais de zeólitas que possam ser explorados comercialmente. No nordeste do Brasil existe a ocorrência de zeolitas sedimentares relacionadas a arenitos descoberta nos anos 2000. Estes arenitos são constituídos de quartzo, argilominerais e zeolitas naturais (estilbita). O objetivo geral desse trabalho foi avaliar se esta zeólita natural presente no arenito possui atividade pozolânica satisfatória para ser empregada como adição mineral em cimentos Portland. No programa experimental o arenito zeolítico passou por beneficiamento através da remoção, por peneiramento, do quartzo e outros minerais inertes, de modo a concentrar a zeólita estilbita e com isto verificar as propriedades pozolânicas deste mineral. No estudo experimental foram empregadas as técnicas de difração de raios X, calorimetria, ensaios químicos e de determinação da atividade pozolânica em argamassas de cal hidratada e cimento Portland. Os resultados mostraram que o arenito zeolítico acelerou a hidratação do cimento Portland devido a extrema finura do material. O arenito apresentou atividade pozolânica, sendo a estilbita responsável por este comportamento. Entretanto, a reatividade foi ligeiramente inferior ao mínimo exigido para ser empregado em escala industrial como pozolana. Estudos complementares são necessários para averiguar se o tratamento térmico entre 300 °C e 500 °C pode aumentar a atividade pozolânica do arenito devido a destruição da estrutura cristalina tanto da estilbita quanto da esmectita presente no arenito.

Ocorrência do metapneumovírus humano nas infecções respiratórias agudas em estados da região nordeste do Brasil

As doenças do trato respiratório são responsáveis por uma significativa taxa de absenteísmo laboral bem como por elevados índices de morbidade e morte, entre as quais as infecções respiratórias aguda (IRA) representam as maiores queixas nos serviços de atendimento médico-ambulatorial em todo o mundo. Os vírus são considerados os principais agentes etiológicos das IRA, atuando seja como patógeno principal ou predispondo às infecções bacterianas secundárias, entre eles encontra-se o Metapneumovirus Humano (HMPV). Este vírus foi identificado em 2001 apresentando-se como um importante agente causador de IRA adquirida na comunidade. É um vírus cosmopolita que causa doenças respiratórias semelhantes ao Vírus Respiratório Sincicial. No Brasil, são relativamente escassos os relatos da ocorrência do HMPV na população. O objetivo deste estudo é investigar a ocorrência de Metapneumovírus Humano (HMPV) em pacientes com diagnóstico clínico de infecção respiratória aguda (IRA) na Região Nordeste do Brasil. Entre o período de Junho de 2009 a Setembro de 2010, pacientes oriundos de atendimentos em unidades de atenção básica ou hospitalar de cinco estados da Região Nordeste, foram submetidos a coleta de espécimes para detecção a partir de técnicas de biologia molecular. Análises estatísticas foram utilizadas para escolha do tamanho amostral (545) e tratamento dos resultados obtidos. O estudo mostrou uma positividade de 4.7% para HMPV, sem a existência de uma faixa etária específica para a ocorrência da infecção. Ocorreu uma prevalência do sexo feminino entre os casos positivos, entretanto, sem significado estatístico. O pico de positividade para o vírus (n=16) mostrou existir no terceiro trimestre do ano em todos os Estados investigados. Neste estudo, foi possível descrever a ocorrência de HMPV na Região Nordeste, afetando pacientes portadores de infecção respiratória aguda, tanto acompanhados ambulatorialmente como hospitalizados, que preencheram critério clínico para Síndrome Respiratória Aguda Grave.

Simulação da produtividade de cana-de-açúcar (Saccharum officinarum L.) na região nordeste do Brasil, utilizando o modelo DSSAT

The objective of this study was to simulate the potential stem and sugar yield of sugar cane (Saccharum officinarum L.) in the Northeastern Brazil (Petrolina-PE and Teresina-PI) and analyze 4 varieties in different planting seasons in two environments: irrigated and rainfed cultivars. The model of simulation was DSSAT/CANEGRO (Decision Support System for Agrotechnology Transfer) and the four sugar cane varieties were as follows: RB86 7515, CTC 4, CTC 7 and CTC 20 (all in 1.5 year cycle). Analysis of variance was performed on the results and means were compared using the Tukey test with probability level at 5%. March is the recommended month for planting in Teresina, PI. In Petrolina, PE, rainfed planting is not advisable because of the extended water deficit all year long. In an irrigated environment, no difference was found concerning stem yield as a function of planting season, for all varieties in the study regions. The stem and sugar yields were always higher in irrigated environment as compared with those in rainfed environment in all municipalities and study varieties. The simulation model provided good estimate of stem and sugar yields as compared with experimental data in Teresina, PI.

A plasticidade acústica de uma população de Boto - Cinza, Sotalia Guianensis (Van Banédén, 1864) (Cetacea, Delphinidae), na região Nordeste do Brasil

The environmental characteristics can modify the acoustics of a species due to habitat, time of day and year. Therefore, this study investigated the relationships between seasons, tide, daily cycle of tides, times of day and different habitat and noise emission of S. guianensis. Sound recordings occurred in the Curral’s Cove and Lagoon Complex of Guaraíras (CLG) in the municipality of Tibau do Sul/RN. Whistles are emitted with lower frequency during rainy season and spring tide while clicks are higher; whistles, clicks and calls have higher frequency during ebb tide. These modifications can be related with turbidity and prey availability. The whistles and clicks occurrence are higher at night probably because luminosity is lower. Furthermore, the whistles and clicks frequency reduction overnight allows the sound to travel longer distance and helps the view which is limited; but the minimum frequency increase was needed to catch the prey. The low occurrence of calls could be related to the small group size. The acoustic changes at night may be partly influenced by light levels as prey availability that is larger in this period. Whistle frequencies and click initial frequency are higher in CLG than Curral’s cove that permitted good precision. However, click central frequency is lower and may be connected to tracking the area. Several factors may be associated with such modifications as background noise, bottom and others. This study supports the hypothesis that S. guianensis presents an acoustic plasticity according to the local conditions where the species is embedded and adapts to the environmental changes.

Impacto do Programa Saúde da Família sobre indicadores de saúde da criança em municípios de grande porte da região Nordeste do Brasil

The present study carried out in the context of the Baseline Studies of the PROESF was aimed at evaluating the impact of the Family Health Program (PSF) on indicators for child health in cities with more than 100,000 inhabitants in the Brazilian Northeast. Four cities were investigated. In each one, twenty censual sectors were selected randomly from areas covered by the PSF and compared with twenty sectors selected from areas not covered by the PSF on the basis of socioeconomic criteria. In most cases, no significant differences were found between the areas covered and not covered by the PSF. The only difference found was a significantly lower rate of hospital admissions due to diarrhea but this was on account of the Program of Community Health Agents. The PSF exerted no additional effect on the reduction of this indicator. It was also observed that the way by which the program is implemented in each city interferes directly in the results. Thus, there is no basis for considering the PSF per se ineffective or not differing from other programs with regard to its health care patterns. An evaluation of the PSF would necessarily have to include an analysis of the way the program is implemented and conducted in each case, besides considering its general socioeconomical and political characteristics.
