Avaliação do conhecimento e de habilidades clínicas em saúde sexual e reprodutiva na graduação de medicina

No Brasil, a despeito das conquistas obtidas a partir da implantação do Sistema Único de Saúde e dos avanços legais e institucionais na atenção a diversos problemas relacionados ao gênero, a incorporação de temas relacionados aos direitos humanos, sexuais e reprodutivos no contexto da formação profissional em saúde permanece deficiente. Este trabalho teve como objetivos avaliar a inserção da temática saúde sexual e reprodutiva no currículo do curso de graduação em Medicina, por meio do emprego de avaliações de conteúdo cognitivo, procedimental e atitudinal. Trata-se de estudo de intervenção educacional envolvendo alunos do internato do curso de Medicina da UFRN. Foram utilizados os seguintes métodos avaliativos: prova escrita, exame clínico objetivo estruturado (OSCE) e Mini-CEX. Como variáveis explicativas foram consideradas o sexo, idade e participação prévia no componente curricular optativo Saúde Reprodutiva . A avaliação do processo constou da aplicação de questionários de satisfação e entrevistas acerca dos métodos avaliativos utilizados. Considerando os três métodos avaliativos empregados, 183 estudantes participaram do estudo, com média de idade de 24,5 ± 2,2 anos, sendo 52,5% do sexo masculino e 47,5% do sexo feminino. No contexto geral, observamos concordância entre os desempenhos dos estudantes nas avaliações de conteúdo cognitivo, procedimental e atitudinal. A participação dos estudantes no componente curricular eletivo Saúde Reprodutiva mostrou-se associada com melhor desempenho em algumas dimensões da avaliação cognitiva e na avaliação com o Mini-CEX, em relação às competências de anamnese, profissionalismo e qualidades humanísticas, relação médico paciente e desempenho global. A análise da fidedignidade entre os avaliadores na avaliação com o método OSCE mostrou-se adequada (alfa de Cronbach superior a 70%) em relação ao desempenho global e aos aspectos técnicos das competências avaliadas, observando-se baixa confiabilidade na avaliação da comunicação médico-paciente. O presente trabalho constitui-se numa experiência educacional inovadora e pioneira no âmbito da educação médica brasileira no que tange à inserção da temática de saúde sexual e reprodutiva na graduação, sugerindo-se um impacto positivo da iniciativa na formação do médico generalista na UFRN. A avaliação de conhecimentos, habilidades e atitudes em saúde sexual e reprodutiva na graduação de Medicina mostrou-se factível, com alta concordância entre os diferentes métodos empregados. Os métodos OSCE e Mini-CEX podem ser aplicados ao contexto da saúde sexual e reprodutiva, possibilitando a avaliação de competências clínicas relevantes para a formação do médico generalista e que habitualmente não são contempladas nas avaliações rotineiramente realizadas na graduação

Nesta terra, em se plantando tudo dá? Política de Soberania e Segurança Alimentar e Nutricional no meio rural paranaense, o caso do PAA

O tema proposto nesta tese vai ao encontro do atual debate em curso no Brasil e no mundo acerca de duas dimensões da cadeia agroalimentar: produção e consumo. Desse modo, as questões de como se dá essa relação frente às estratégias locais por diferentes atores, terá ênfase. Para isso, como campo empírico foram escolhidos três municípios localizados no território Centro-Sul do estado do Paraná: Irati, Inácio Martins e Fernandes Pinheiro que desde 2004 estão inseridos no Programa de Aquisição de Alimentos (PAA), mais especificamente na modalidade Compra com Doação Simultânea (CDS). A hipótese que embasa este estudo é de que o PAA poderá ser capaz de assumir um caráter estruturante - a partir do seu viés pedagógico, capacidade organizativa de produção, manutenção da diversidade ou resgate da policultura (e aqui se privilegia a agroecologia), bem como uma alternativa viável de acesso a um tipo de mercado (mercado institucional) -, não por altruísmo dos atores, mas por ser mais vantajoso ser parte integrante, do que estar à parte do processo, aliando a isso melhorias nas condições alimentares tanto das suas famílias, quanto das entidades receptoras. O objetivo principal foi analisar as relações sociais e as práticas alimentares de um grupo de agricultores(as) agroecológicos entre as responsáveis pelo recebimento dos alimentos doados buscando compreender se o PAA possibilita a Soberania e Segurança Alimentar e Nutricional (SSAN) de grupos sociais (como das famílias rurais) e das pessoas atendidas por estas entidades. A metodologia utilizada foi a de estudo de caso. Como procedimentos foram empregados entrevistas semi-estruturadas e aplicação de questionários como: Escala Brasileira de Insegurança Alimentar(EBIA) e Questionário de Frequência de Consumo Alimentar(QFCA). A amostra foi composta por agricultores(as)/ fornecedores(as) do PAA, nutricionistas e, coordenadora de uma das entidade dos seus produtos é, de fato, o que os mobiliza a continuar produzindo em maior diversidade e quantidade. Após a vivência dos(as) agricultores(as) /fornecedores de estarem inseridos no Programa foi possível para estes atores se sentirem parte do processo e, assim, repensar suas práticas de produção de alimentos, seja ela destinada ao autoconsumo, seja voltada à comercialização. Para além da discussão acerca da produção destinada ao autoconsumo, ficou claro o processo de recampesinização entre as famílias de agricultores(as). O processo de (re)conexão se apresenta de forma frágil, considerando, sobretudo, as considerações feitas pelas mediadoras. Trazer à tona o debate acerca da produção-consumo de alimentos, tanto na perspectiva de quem produz, como na de quem consome, e tomando por referência a operacionalização de políticas públicas, viabiliza a ampliação de debates e a concretização de ações mais contundentes numa perspectiva de minorar a situação de vulnerabilidade (social e alimentar) e de pobreza rural

Televisão universitária do RN (TVU): contribuição para a democratização da informação e a difusão do conhecimento científico produzido pela universidade

In this thesis we propose to investigate the contribution that the Universitary Television from Rio Grande do Norte state, Brazil (TVU RN), offers to democratization of information and diffusion of the scientific knowledge produced by the Federal University of Rio Grande do Norte (UFRN) from the perception of their own students. We adopt the basic assumption in wich the TVU RN needs to be connected with the scope of the current UFRN policy, since plays an important role regarding democratization and social inclusion policies in UFRN. We support the thesis that TVU UFRN offers important information for those who are part of academic culture (COULON, 1995a; 1995b, CHARLOT, 2000; BOURDIEU, 2007, 2005, 1997, 1996, 1975), as well as for society in wich it is inserted, since it contributes to the dissemination of scientific knowledge and relevant information about the university. We consider TVU RN a Public Sphere (HABERMAS, 2002; 2003a, 2003b; 2003c; 1999; 1989) conducive to discussion of issues involving higher education. Researches on Universitary Television are recent and some studies on it advanced in the way to define it and present it as a means of dissemination of scientific knowledge (ROCHA, 2006; COUTINHO, 2006; CALLIGARO, 2007; AIRES, 1999; PORCELLO, 2002; PRIOLLI, 2003, 2008, 2009; MAGALHÃES, 2002, 2008; RAMALHO, 2008; 2010; CARVALHO, 2006). For our investigation we chose the combination of quantitative and qualitative methods, both equally valid and accepted by many authors (FLICK, 2009; BAUER; GASKELL, 2002; RICHARDSON, 1999; LAVILLE; DIONNE, 1999). We developed a questionnaire initially with objective questions ending up with open questions of free text. The questionnaire was developed and hosted from a tool of Google Docs and the link to the webpage containing those questionnaires was sent by e-mail by the Permanent Commission of Vestibular of UFRN, COMPERVE, for all university students who were with their registration (status) active in the COMPERVE registers of the second half of 2010. The analysis of this material was performed using the techniques of content analysis and, within this mode was chosen thematic analysis considered appropriate for both qualitative and quantitative research (BARDIN, 2004; MINAYO, 2002). The investigation found that although most students consider that the TVU RN contributes to the democratization of information and dissemination of scientific knowledge produced in university, and moreover to arouse the interest of the academic community, still has not yet become an object of interest of the entire academy. Therefore, the research highlights the relevance and abrangency of further studies on the TVU RN due to the strategic role it plays in this new reality of public universities in the country. In addition, we suggest to the UFRN managers that they put TVU within the hall of discussions in order to receive the so much needed investment for any university organ

Body art, existência e conhecimento :a percepção do corpo na Educação Física

In the Renaissance, the anatomy project a map of the body. Since then, the human body has been investigated for innumerable techniques, configuring new landscapes on the condition human being and the proper knowledge. In accordance with Merleau-Ponty (1975), All technique is body technique. It configures and extends the Metaphysical structure of our meat. In this direction, any intervention in the human body, a tattooing, a surgery or a performance, extends the perception and the directions of the existence of the subject. Merleau-Ponty (1975) still affirms, that all technique presents objective interventions. However, the body, ahead of these interventions, doesn t have to be considered only object, but subject that, from the interventions, attributes sensible and meanings through the movements, also being this its way of being in the world. Searching to extend this reflection on the discontinuities between the object body and the subject body, as well as, with the objective to reflect on the relation between the corporal techniques and the production of the subjectivity and the knowledge of the physical education, we reflect on the body art, as one technique of body that marks the exterior of the body, exteriorizing the subjectivity, to search new means to the body and that ahead of this, we believe being able to project innumerable directions for the corporal transformations in the contemporarily. As a method for our reflection in we will support them in the phenomenology. IT presents as a new ontology, in which distinction does not occur enters the operating paper of the citizen that knows and the influence of the known object. The phenomenological understanding of body will be able to contribute with the knowledge of the Physical Education, a time that gives us important arguments on the experience of the body in relation with the nature, the culture, history. To be a body is to be tied to a world that we do not possess completive, but that we do not cease to search it

Validação de instrumentos para avaliação da habilidade e do conhecimento acerca da medida da pressão arterial

This study aimed to validate tools for evaluating the ability and knowledge about blood pressure (BP) among nursing students. It is a cross-sectional, descriptive, quantitative and methodological study accomplished at the Universidade Federal do Rio Grande do Norte (UFRN), Universidade do Estado do Rio Grande do Norte (UERN) and a private university of the state. The sample consisted of 27 judges of research selected from the inclusion criteria: nursing, teachers of the semiology and/or semiotics discipline, with at least 1 year of experience, being from UFRN, EEN, UERN and private university of the state and and agree to participate voluntarily with the signing of the consent form. The research was development in three stages: construction of two instruments based on the scientific literature, resulting in a structured checklist consists of 28 items and a knowledge questionnaire with 12 questions; submission of the instruments to the judges, in the period from June to September 2012, which should evaluate each item in appropriate , appropriate with changes and inappropriate , addition to making an overall assessment of each instrument based on 10 requirements; validation and verification to the level of agreement among the judges, through the application of Kappa and Content Validity Index (CVI). Was used the consensus level greater than 0.61 (good) to the Kappa index and greater than 0.75 for CVI. Was approved by the Ethics in Research / HUOL. After being coded and tabulated, the data were analyzed using descriptive statistics. Of the 27 judges who evaluated the instrument, 77.8% are female, with a mean age of 36.6 (± 9.0) years, 63.0% worked in UFRN, 74.1% had academic master and 63.0% worked exclusively on teaching. Average length of teaching experience was 7.9 (± 8.0) years and in the semiology and/or semiotics discipline of 5.5 (± 6.7) years. In the judgment of structured checklist and questionnaire of knowledge about blood pressure mensurement any item/question was considered inappropriate since all obtained level of agreement within the indices established (CVI> 0,75 E Kappa> 0.61). In relation to structured checklist, of those 28 items present, 9 showed perfect concordance index (CVI = 1.00, Kappa = 1.00) and another 19 were considered appropriate with changes, especially with regard to clarity and vocabulary. In the questionnaire of knowledge, among the 12 questions that comprised, 7 had perfect concordance index and the others were considered appropriate with changes as requirements as clarity, vocabulary, and feasible sequence of instructional topics. In terms of a overall evaluating of instruments, the structured checklist got CVI of 0.94 and Kappa of 0.89 and the knowledge questionnaire, CVI of 0.97 and a kappa of 0.94. Both instruments proved to be valid as to their content, configuring it as clear and objective tools of assessment of knowledge and ability on blood pressure, being of nursing students as well as others students and health professionals, since the use of valid measures seeking to reduce the risk of distorting the results

O conhecimento e as atitudes das famílias de pacientes em tratamento em tuberculose na atenção primária à saúde

This study thus sought to examine knowledge about TB and attitudes of patients families in disease treatment in Primary Health Care in Natal- RN. To this end, a cross-sectional study was undertaken through a questionnaire with families of patients diagnosed with TB and follow up by APS from Natal. The study subjects were recruited from a non-probabilistic way, by convenience, contemplating a sample of 50 families. Among the criteria considered for inclusion of subjects, older than 18 years were considered, as well as residing with the TB patient and in Natal and availability to participate in the research. Data collection was performed by own researcher and an assistant, through a questionnaire with families of patients diagnosed with TB following the double independent digitalization of data. In the analytical phase, was initially conducted an exploratory phase and univariate data, with description of the position measurements (mean, median, mode) and dispersion (confidence interval and standard deviation). In bivariate analysis, it was conducted an intersection of dependent variables of knowledge e and changes of attitude dichotomous, with each of the independent variables, using contingency tables and calculating the chi-square test and, when appropriate, the Fisher exact test. In 2x2 tables, calculated the odds ratio (OR) with confidence intervals of 95% (95% CI). From the selected sample, 43 (86%) subjects were female, average age and median respectively of 46.64 and 46.50 years, 25 (50%) had elementary school. The knowledge expressed by family members about TB was considered satisfactory. However, the lack of interest of the family (54%) in seeking information about tuberculosis; the wrong way of reply in relation to the organism causing the disease (64%); the water content (62%) and contaminated food (54% ) as a means of spreading TB was a weakness identified in the investigation. Regarding the time of transmission, 90% of respondents indicated not know or answered wrong. From investigated independent variables, only two were associated with lack of knowledge of TB, and they did not have religion (OR: 0.146, 95% CI: 0.027 to 0.800) and income below 1, 7 minimum wages (OR: 0.155, 95% CI: 0.029 to 0.813). Thus they seem to exercise a protective effect on this outcome. As for the changes in attitude, most of the found variables had no association with statistical significance, except no internet access (OR: 0.212, 95% CI: 0,048-0, 935). Most attitudes were positive in relation to TB patient. Results have demonstrated weaknesses in TB care, which has taken on a more individual and welfare character. Data not only express health outcomes produced by health services, but also the political and social situation of the families that are affected by TB

Validação de instrumentos para avaliação do conhecimento e da habilidade acerca da sondagem vesical de demora

That study had the aim to validate an instrument to evaluate the knowledge about the Urinary Catheterization (UC) in males. Cross-sectional, descriptive, quantitative and methodological study, accomplished in Universidade Federal do Rio Grande do Norte (UFRN), Universidade do Estado do Rio Grande do Norte (UERN) and a private university from Rio Grande do Norte. Sample of 27 judges selected from the inclusion criteria: registered nurses, discipline of semiology and/or semiotics teachers, with at least 1 year of experience in the disciplines, to work at UFRN, UERN or in private university and agree to participate voluntarily with the signing of the Consent Form. Study developed in three stages: a) elaboration of twos instruments based on the scientific literature, resulting in a structured observation script type checklist consisting of 36 items and a knowledge questionnaire with 12 questions; b) submission of instruments to judges from June to September 2012, which should evaluate each item in "adequate," "adequate with changes" and "inappropriate", and make an overall evaluation of each instrument based on 10 requirements; c) and validation with a verification of the agreement level among the judges, through the application of Kappa Index (K) and Content Validity Index (CVI). It was used the consensus level higher than 0.60 (good) for Kappa Index and higher than 0.70 for CVI. The research project had favorable opinion from the Ethics in Research/HUOL (CAAE n. 0002.0.294.000-10). After being coded and tabulated, the data were analyzed using descriptive statistics. Of the 27 judges who evaluated the instrument, 77.8% are female, with a mean age of 36.6 (± 9.0) years, 63.0% worked in UFRN, 74.1% had master degree and 63.0% worked exclusively on teaching. The experience time mean in teaching was 7.9 (± 8.0) years and in the disciplines of semiology and/or semiotics in nursing was 5.5 (± 6.7) years. In judgment of the checklist and knowledge questionnaire, no step/question was considered inappropriate, since all achieved level of agreement within the established values. All the checklist steps obtained good to excellent K (between 0.60 and 1.00). Of the 36 items, 25 had excellent K (0.75 ≤ K <1.00) and excellent total K (K = 0.83). Regarding the IVC, all steps reached levels above 0.70 (between 0.74 and 1.00) and CVI total was 0.90. All questionnaire questions evaluated separately (K from 0.60 to 0.93 and CVI from 0.74 to 0.96) and generally (K from 0.79 to 1.00 and CVI from 0.89 to 1.00) had evaluation levels of content validity within the established values. The instruments were reformulated based on the agreement levels between judges and international guidelines, dissertations and scientific articles. Both instruments proved to be valid regarding to their content, allowing a clear and objective evaluation of knowledge and skills about UC, both nursing students as well as other students and health professionals, since the use of valid measures seeking the reduction of the risk of the results distorted

Qualidade de água como tema para a socialização do conhecimento científico em região semi-árida brasileira

During the dry and rainy periods, in the Piranhas-Assu river hydrographic basin, variations in bacterioplankton and trophic state indexes were studied in the lotic and lentic environments. The means of total bacterial density wavered in the order of 107 organisms. mL-1 and they were higher in the rainy period. Cocci bacteria were numerically predominant in all sampling points, influencing the total abundance of bacterioplankton. Total bacterial biomass varied from 659 to 1997,3 µgC.L-1 due to the high values of filaments cellular volume. Total phosphorus amounted 108 µg.L-1 and it had a positive correlation with chlorophyll a (r = 0,94; p < 0,05) during dry period, when these variables presented higher concentrations. There wasn t a high spatial variation. The low transparency of water and the phosphorus and chlorophyll concentrations indicated eutrophic or hipereutrophic levels in studied points of reservoir. These variables, associated with high density and biomass values found, alert to the necessity of a constant monitoring of the semi-arid aquatic ecosystems, where the quality of water is affected by dry occurrence

Caracterização geológico-geofísica do meio aqüífero fissural : uma contribuição aos modelos de fluxo e armazenamento de água subterrânea

Northeastern Brazil is mainly formed by crystalline terrains (around 60% in area). Moreover, this region presents a semi-arid climate so that it is periodically subject to drought seasons. Furthermore, ground water quality extracted fromwells usually presents poor quality because of their high salinity contents. Nevertheless, ground water is still a very important source of water for human and animal consumption in this region. Well sitting in hard rocks terrains in Northeastern Brazil offers a mean success index of aboul 60%, given that a successful siting is defined by a well producing at least 0.5 m³/h. This low index reveals lack of knowledga about the true conditions of storage and percolation of ground water in crystalline rocks. Two models for structures storing and producing ground water in crystalline rocks in Northeastem Brazil have been proposed in the literature. The first model,tradnionally used for well sitting since the sixties are controlled by faults or fractures zones. This model is commonly referred, in Brazilian hydrogeological literature, as the "creek-crack" model (riacho-fenda in Portuguese). Sites appearing to present dense drainage network are preferred for water well siting - particularly at points where the drainages cross-cul each other. Field follow up work is usually based only on geological criteria. The second model is the "eluvio-alluvial through" (calha eluvio-aluvionar in Portuguese); it is also described in the literature but it is not yet incorporated in well sitting practice. This model is based on the hypothesis that reclilinear drainages can also be controlled by the folietion of the rock. Eventually, depending upon the degree of weathering, a through-shaped structure filled with sediments (alluvium and regolith) can be developed which can store and water can be produced from. Using severalfield case studies, this Thesis presents a thorough analysis ofthe two above cited models and proposes a new model. The analysis is based on an integrated methodological approach using geophysics and structural geology. Both land (Resitiviy and Ground Penetrating Radar- GPR) and aerogeophysical (magnetics and frequency domain eletromagnetics) surveys were used. Slructural analysis emphasized neolectonic aspects; in general, itwas found that fractures in the E-W direction are relatively open, as compared to fracturas inthe N-S direction, probably because E-W fractures were opened by the neotectonic stress regime in Northeastern Brazil, which is controlled by E-W compression and N-S extension. The riacho-fenda model is valid where drainages are controlled by fractures. The degree of fracturing and associated weathering dictale the hydrogeological potential of the structure. Field work in structural analogues reveals that subvertical fractures show consistent directions both in outcrop and aerophotograph scales. Geophysical surveys reveal subvertical conductive anomalies associated to the fracture network controlling the drainage; one of the borders of the conductive anomaly usually coincide wih the drainage. An aspect of particular importance to the validation of fracture control are the possible presence of relalively deep conductive anomalies wihoul continuation or propagalion to the surface. The conductive nature of lhe anomaly is due to the presence of wealhered rock and sedirnenls (alluvium and/or regolilh) storing ground waler which occur associated to the fracture network. Magnetic surveys are not very sensisnive to these structures.lf soil or covering sedirnents are resislive (> 100 Ohm.m), GPR can ba used to image precisely lhe fracture network. A major limialion of riacho-fenda model, revealed by GPR images, is associated to the fact thal subhorizontal fractures do play a very important role in connecting the fracture network, besides connect shallow recharge zones to relalively deep subvertical frecture zones. Iffractures play just a secondary control on the drainage, however, r/acho-fenda model may have a very limiled validny; in these cases, large portions oflhe drainage do nol coincide wilh frectures and mosl oflhewells localed in lhe drainage surrounding would resull dry. Usually, a secondary conlrol on lhe drainage by Ihefraclure networkcan be revealed only wilh detailed geophysical survey. The calha elClv1o-aluvlonarmodel is valid where drainages are conlrolled by folialion. The degree 01 wealhering 01 lhe lolialion planes dictales lhe hydrogeological polenlial 01 lhe slruclure. Outcrop analysis reveals Ihal lolialion and drainage direclions are parallel and Ihal no Iraclures, orfraclures wilh diflerent directions 01 lhe drainage direclion occur. Geophysical surveys reveal conduclive anomalies in a slab lorm associaled 10 lhe Ihrough 01 lhe wealhered rock and sedimenls (alluvium and/or regolith).

Certainly, Ihis lacl could explain at leasl a part of lhe failure index in well sitting. The model wealhering sack (bolsllo de Intempertsmo in Portuguese) is proposed to explain cases where a very inlensive wealhering occur over lhe crystalline rock so Ihal a secondary inlerslilial porosity is crealed. The waler is Ihen stored in lhe porous of lhe regolilh in a similar mannerlo sedimentary rocks.

Conhecimento sobre energia eólica: um estudo exploratório a partir das redes semânticas naturais de estudantes da cidade de Natal

The human being has a fundamental role in issues concerning scarcity of energy resources as well as in the success of technologies which favor the use of renewable sources, such as wind energy. But what does wind energy mean for people? What are the psychological meanings concerning this term? Aiming to answer these questions, the general objective of this dissertation was to identify and to analyze the knowledge about wind energy taking into account a network of psychological meanings. One hundred and ninety one (191) university students from Natal-RN participated in the study, being male the majority (53%); aged between 17 and 51 years old (M=23.3 years; SD=5.7). Participants responded to self reports using the Natural Semantic Networks (NSW) technique, as well as to several sociodemographic questions. The results showed a consistent, positive and useful general semantic network. In this semantic network, knowledge about wind energy was represented by words that correspond to the appeal of (pro) environmental stance (e.g., clean and nature), that evinced both the technological aspect (e.g., force) and the economic aspect (e.g., economy). Results from different groups were also analyzed. The first set of groups (non-environemental and environmental) was divided considering the course (e.g., ecology and economy). The second set of groups(non-caretaker and caretaker) was divided based on the practice of environmental care expressed. Subtle differences were observed in the semantic networks of caretakers, who emphasized environment, an attribute not mentioned by non-caretakes. This indicates a construction of knowledge that is influenced by the presence or absence of the environmental commitment. Such findings may be useful in the construction of instruments for surveys and in the development of public and educational policies. Additionally, they may assist the media towards a more objective performance concerning wind energy

HIV/AIDS: um perfil epidemiológico do vírus e uma análise das práticas seguras, conhecimento e percepção de mulheres

In recent decades, the debate surrounding the consequences of the HIV has passed by great changes. Earlier, prevention campaigns focused risk groups then risk behaviors and ultimately vulnerability. Furthermore, over the years, the dimensions of HIV that emerged in the social environment are these: internalization, heterosexualization, impoverishment and feminization. Based on these contexts, the composition of this study comprises two papers: the former has the overall objective to analyze the epidemiology and incidence of HIV in Brazilian regions in the period from 1980 to 2012; the latter, it aims to find out whether there is the relationship among safe practices, knowledge and perception of women residents in Manaus and Boa Vista cities on the infection by HIV. In paper 1, it was used information from the Health Ministry, as a data source.
