Sistema de reciclagem de veículos em final de vida : uma proposta ambientalmente mais sustentável para o cenário brasileiro

Coimbra, Núbia dos Santos January 2017 (has links)
A escassez de sistemas consolidados de reciclagem de veículos no Brasil e o grande volume de veículos em final de vida (VFVs) junto aos pátios do Departamento Estadual de Trânsito do Rio Grande do Sul - DETRAN/RS serviram de base para o desenvolvimento desta dissertação. Em face disso, o objetivo deste trabalho foi desenvolver um sistema de reciclagem de VFVs ambientalmente mais sustentável, a partir de exemplos globais de melhores práticas adotadas, atendendo à legislação vigente do país. Para tanto, a presente dissertação é composta por dois estudos fundamentados em revisões sistemáticas e em estudos de caso. Inicialmente, como resultado da primeira revisão sistemática, foi realizada a comparação de sistemas de gestão de reciclagem de veículos, identificados em 25 países. Essa comparação possibilitou ampliar o conhecimento de tecnologias e de procedimentos adotados em diferentes realidades, permitindo a proposição de oito políticas a serem adotadas em âmbito nacional, bem como três ações de melhoria ao atual sistema do DETRAN/RS. Em seguida, a segunda revisão sistemática permitiu a proposição de um sistema ambientalmente adequado para reciclagem de VFVs, que sirva de base para a futura padronização de processos de reciclagem, visando a potencial criação de centros especializados em reciclagem de veículos (CERVs). Diante do exposto, os resultados da pesquisa demonstraram que o tema da reciclagem de veículos está inserido num cenário mais amplo, necessitando da participação de todos os stakeholders envolvidos no processo, a exemplo: (i) das montadoras e fabricantes de peças, no desenvolvimento de tecnologias automotivas; (ii) dos entes federados, na criação de legislações mais rígidas e específicas, com foco na economia circular; e (iii) da sociedade na busca de produtos eco-amigáveis. Por fim, conclui-se que, associado às políticas e ações de melhoria sugeridas, a adoção do sistema ambientalmente adequado para reciclagem de VFVs proposto, poderá acelerar a criação de um ambiente favorável para o desenvolvimento e a consolidação da reciclagem no país. / The scarcity of consolidated vehicle recycling systems in Brazil and the huge amounts of endof- life vehicles (ELVs) at the Transit State Department of Rio Grande do Sul - DETRAN/RS courtyards served as the basis for the development of this Masters dissertation. Therefore, the objective of the work was to develop an environmentally more sustainable ELVs recycling system, based on global adopted best practices, without disregarding the country's current legislation. So, this dissertation is composed of two studies based on systematic reviews and on case studies. Initially, as a result of the first systematic review, a comparison of vehicle recycling management systems was carried out, identified in 25 countries. This comparison allowed the increasing of the knowledge about technologies and procedures adopted in different realities, making possible a proposal of educational policies to be adopted at national level, as well as three improvement actions for the current system of the DETRAN/RS. Subsequently, a second systematic review allowed a proposal for a suitable environmentally recycling system for the ELVs, which serves as the basis for a standardization of recycling processes, aiming the potential creation of specialized centers for such processes (CERVs). Considering this, the research results showed that the theme of product recycling is inserted in a broader scenario, requiring participation of all stakeholders involved in the process, such as: (i) the automakers and parts manufacturers, in the automotive technologies development; (ii) the federal entities, in the creation of more rigid and specific legislation, focusing on the circular economy; and (iii) the society in the search for eco-friendly products. Finally, it is concluded that, associated with the suggested policies and improvement actions, the adoption of the proposed environmentally appropriate system for the recycling of the ELVs, may accelerate the creation of a favorable way to the develop and consolidate the recycling in our country.

The role of perseverative negative thinking in predicting depression, anxiety and quality of life in people with coronary heart disease

Trick, Leanne Victoria January 2017 (has links)
Depression is common in people with coronary heart disease (CHD) and is associated with worse physical outcomes. The nature of the causal association between CHD and depression, and the mechanism underpinning the association of depression with worse physical outcomes, remains unclear. Perseverative negative thinking may contribute to the development of depression in people with CHD. The aim of this thesis was to investigate the prospective association of perseverative negative thinking with depression, anxiety and worse physical outcomes in people with CHD, and to explore factors that may mediate this association. First, a systematic review identified 30 studies, of which the majority found an association between measures of perseverative negative thinking and subsequent depression, anxiety or emotional distress in people with long term conditions. Studies that controlled for covariates showed more mixed results, though the majority (15 / 25) still supported a significant association, with effects being small in magnitude. Findings were limited mainly to the association of rumination and/or catastrophizing with subsequent depression, and study quality was limited. Next, in an observational prospective cohort study 169 inpatients and outpatients with recent acute coronary syndrome (ACS) completed self-report assessments of rumination (Ruminative Responses Scale brooding subscale), worry (Penn State Worry Questionnaire), depression (Patient Health Questionnaire-8), anxiety (Beck Anxiety Inventory), and health-related quality of life (EuroQol-5D health-related quality of life, Seattle Angina Questionnaire) after hospitalisation, and at 2 month and 6 month follow-up. Additionally, assessments of potential mechanistic factors (social support, problem solving, instrumental behaviours and negative cognitive biases) were made. Baseline brooding was a significant independent predictor of depression at 6 months after controlling for the effects of important confounding variables, accounting for 2% of the variance. Findings suggested that the association of brooding with depression may be explained by deficits in problem solving ability. Rumination and problem solving may provide useful targets for the development of evidence-based interventions to improve depression among people with CHD, although the findings presented here fall short of proving a causal relationship. Future trials could be used to investigate the causal nature of the association of rumination and problem solving with depression in people with ACS.

Intersections Between Violence and Health Promotion Among Indigenous Women Living in Canada

Williams, Julie 07 May 2019 (has links)
Violence against Indigenous women is a major public health concern worldwide and Canada is no exception. Multiple forms of violence inform the broader context of violence against Indigenous women. Nurses are likely to encounter Indigenous women in a variety of settings, but evidence suggests that nurses may lack understandings of violence. This thesis explored the following question: How does extant qualitative research conducted in Canada, contribute to understanding the health and wellbeing of First Nations, Métis and Inuit (Indigenous) women who have experienced violence? During the development of this thesis, significant gaps were highlighted including underrepresentation of Inuit women in the literature, limited focus on health promotion, and lack of methodological approaches to systematic reviews that were participatory and inclusive of the community. Therefore, a secondary aim of this thesis was to privilege perspectives of Inuit women and their communities, by developing a study protocol for a collaborative and community centered approach to reviewing and assessing the extant literature. A configurative and inductive approach based on thematic synthesis was used to systematically search, retrieve, analyze and synthesize extant literature. Post-colonial feminist theory and intersectionality were used as theoretical lenses to emphasize intersections between multiple forms of violence and locate the problem within the broader context of colonization and oppression. Sixteen studies were included in this review, fifteen qualitative and one mixed methods study. Four themes with subthemes emerged based on analysis and synthesis of findings in the included studies: 1) ruptured connections between family and home, 2) that emptiness… my spirit being removed, 3) seeking help and feeling unheard, and 4) a core no one can touch. These themes represent interconnected pathways that influenced health among Indigenous women, and have implications for healthy public policy, clinical practice, and nursing education.

O agrupamento de cuidados no manejo do recém-nascido pré-termo: uma revisão sistemática / The clustered care for handling the preterm infants in the neonatal intensive care unit: a systematic review

Oliva, Cintia Luiza 21 March 2013 (has links)
Introdução: O agrupamento de cuidados é uma estratégia que visa evitar a manipulação intermitente dos neonatos pré-termos, proporcionando um período maior de repouso, fundamental para seu adequado crescimento e desenvolvimento. Esta prática é amplamente utilizada nas Unidades de Terapia Intensiva Neonatal (UTIN). Objetivo: Estabelecer evidências acerca da efetividade do agrupamento de cuidados na organização do ciclo sono-vigília, na estabilidade das respostas fisiológicas e mímica facial em pré-termos com idade gestacional até 32 semanas. Método: Revisão sistemática que identificou estudos publicados e indexados nas bases eletrônicas Cochrane, LILACS, EMBASE, CINAHL, PubMed, Web of Science. Foram utilizados os descritores/termos livres clustered care, neonatal individualized developmental care program OR NIDCAP, kangaroo mother care OR KMC e skin to skin para identificação dos estudos. Além destas bases, foram realizadas buscas por estudos não publicados em revistas indexadas como anais de eventos científicos, teses e dissertações indexadas nas bases eletrônicas de bancos de teses disponibilizados em páginas eletrônicas de universidades e pela ferramenta Google scholar. A análise e seleção das publicações foram realizadas por dois revisores independentes, as publicações com análises discrepantes para inclusão ou não na revisão foram submetidas à avaliação de um terceiro revisor. As publicações que atenderam os critérios de inclusão foram selecionadas para a leitura e análise na íntegra. Após esta avaliação, as que preencheram os critérios de inclusão, foram incluídas na revisão sistemática. Resultados: Foram identificadas 1255 publicações nas bases de dados, das quais 18 foram selecionadas como prováveis inclusão e analisadas na íntegra. Destas, cinco ensaios clínicos randomizados do tipo cross-over foram incluídos na presente revisão. Os sujeitos que compuseram a amostra dos ensaios clínicos analisados foram os neonatos pré-termos com idade gestacional igual ou inferior a 32 semanas. O agrupamento de cuidados foi comparado com um procedimento doloroso. Os resultados mostraram que os RNs apresentam alterações na mímica facial (olhos espremidos), alterações comporamentais (extenção de braços, língua protusa, mãos abertas com adução dos dedos, bocejo) e diminuição na saturação de oxigênio mais significativamente no grupo submetido ao procedimento doloroso comparado ao grupo de cuidados agrupados (p<0,004). No entanto, valores semelhantes nas alterações faciais e fisiológicas ocorreram no grupo submetido ao agrupamento de cuidados e os sinais de estresse avaliados após o agrupamento de cuidados, persisitiu por maior tempo, comparado com a fase de recuperação do neonato no grupo do procedimento doloroso. Quanto à frequência cardíaca, os neonatos com idade gestacional inferior a 30 semanas apresentaram elevados índices quando o procedimento doloroso foi precedido pelo agrupamento de cuidados (p<0,0001). Conclusões: As evidências encontradas sugerem que o agrupamento de cuidados causa alterações na resposta comportamental (ciclos sono-vigília), instabilidade nos parâmetros fisiológicos (frequência cardíaca e saturação de oxigênio) e sinais de estresse demonstrado através da mímica facial (sobrancelhas salientes e sulco nasolabial) em recém-nascidos com idade gestacional menor ou igual a 32 semanas. A adoção da prática de agrupamento de cuidados não garante que os neonatos pré-termos submetidos a este tipo de cuidado apresentem respostas fisiológicas e comportamentais mais estáveis. / Introduction: The clustered care is a strategy to avoid the intermittent preterm infants handling, providing them a longer rest period, essential to their health growth and development. This procedure is widely used in the context of Neonatal Intensive Care Units (NICU). Objective: To establish evidence concerning the effectiveness of the clustered care in organizing the sleep-wake cycle in the physiological responses and facial expressions in gestational age up to 32 weeks preterm infants. Methods: A systematic review that identified the studies published in the Cochrane, LILACS, EMBASE, CINAHL, PubMed and Web of Science electronic databases. The descriptors used to identify the studies were: \"clustered care, neonatal individualized developmental care program OR NIDCAP, kangaroo mother care OR KMC e skin to skin. Also these database, it was identified the studies not published in indexed journals including studies presented in scientific events and thesis and dissertations available in the electronic databases hosted in the universities homepages and publications identified by the Google scholar gate. The selection of publications and analysis of them were performed by two independent reviewers. The publications with conflicting evaluation between the two reviewers were submitted to evaluation by a third reviewer. The publications that met the inclusion criteria were selected for analysis of the full text. After this analysis, those studies that met the inclusion criteria were included in the systematic review. Results: We identified 1255 publications in databases, 18 of them were selected as probable inclusion and were analyzed in its entirety. From these 18 studies, five cross-over randomized clinical trials were included in this systematic review. The subjects who comprised the samples of analyzed trials were premature infants up to 32 week gestational age. The clustered care group was compared with a painful procedure. The results showed that newborns exhibited alterations in the facial expressions (eyes squeezed), behavior changes (arms extension, protruding tongue, open hands with fingers adduction, yawn) and oxygen saturation decreasing more significant in the group undergoing painful procedure compared with the clustered care group (p <0.004). However, similar values in facial and physiological changes occurred in the clustered care group and stress signals evaluated after grouping care, persisted for a longer time compared to the recovery phase in the newborn of painful procedure group. As for heart rate, neonates with gestational age below 30 weeks showed high levels when the painful procedure was preceded by clustered care (p <0.0001). Conclusions: The evidence suggests that the clustered care causes changes in the behavioral responses (sleep-wake cycles), instability in physiological parameters (heart rate and oxygen saturation) and stress signals demonstrated through facial expressions (protruding eyebrows and nasolabial folds) in the premature infants up to 32 weeks gestational age. he grouping of care does not guarantee that the preterm group undergoing care exhibit more stability in physiological and behavioral responses. The adoption of the clustered care practice does not guarantee that the preterm infant underwent to it exhibit more stability in the physiological and behavioral responses.

Attitudes and attitude change in personal travel

Hoffmann, Christin Sylvana January 2018 (has links)
High levels of personal car use have negative effects on the environment and on human health. This thesis presents four empirical studies that aimed to develop our knowledge of personal travel choices, focussing on the malleability of attitudes and their sensitivity in relation to specific contexts and goals. The first study (Chapter 2) presents a systematic review and meta-analysis of mechanisms of travel mode choice. The study provides a comprehensive overview of antecedents of car use and non-car use, including sub-group analyses of different contextual factors. Results also highlight the need for standardised measures and consideration of implicit thought processes. The second study (Chapter 3) employs a repertory grid technique to elicit perceptions of seven different transport modes from high mileage car users and non-car users. Comparisons between car users and non-car users highlight potentially effective and ineffective intervention targets. Findings show how sustainable transport might be promoted amongst a portfolio of travel choices. The third study (Chapter 4) utilises qualitative methods to explore the extent to which individuals’ attitude expressions are changeable. The study demonstrates that all participants hold ambivalent and conflicting attitudes, highlighting specific situations in which those attitudes are more likely to be unstable. Two related priming experiments are presented in the final empirical chapter (Chapter 5). Both use survey methodology to investigate whether manipulating the salience of car-use-incongruent goals can lead to more positive attitudes towards and increased willingness to use non-car travel modes. The study confirms that people who are motivated to make changes are a potentially optimal target group for interventions based on subliminal messages. Overall, the research presented in this thesis introduces context sensitivity into the transport literature and offers novel insights into perceptions of a range of travel modes. Recommendations include relevant avenues for future research, findings are discussed in light of implications for transport policy and practice.

Developing a patient-centred patient-reported outcome measure (PROM) for cognitive rehabilitation after stroke : the Patient-Reported Evaluation of Cognitive State (PRECiS) scale

Patchick, Emma January 2017 (has links)
Cognitive difficulties can persist for months and years after stroke and adversely impact confidence, mood and functional recovery. Stroke survivors, carers and healthcare professionals collectively agree that improving cognition is the number one research priority for life after stroke. Future research should include measurements of outcome that service users deem important. Patient reported outcome measures (PROMs) are a means of gaining patient perspectives that can be standardised for use in a trial. PROMs should be developed with service users to incorporate their priorities but people with cognitive difficulties are often systematically excluded from the development and use of PROMs. Study 1 used qualitative interviews (N=16) to explore stroke survivor perspectives on the important and measureable impacts of persisting cognitive problems. The results of this study generated requirements for a PROM that related to conceptual underpinning and face validity of a measurement tool. Study 2 was a systematic review of existing PROMs related to cognition. 20 Identified PROMs were critically appraised against the requirements generated in the qualitative study. No existing PROMs were identified that met all of the qualitative study review criteria. The next stage described in chapter 3, was to develop a new PROM that: utilised the strengths of existing tools; met qualitative study requirements; and was refined through consultation with different stakeholders, prioritising feedback of stroke survivors with cognitive difficulties. The result of this work was the Patient Reported Evaluation of Cognitive State (PRECiS) scale. Study 3 was a psychometric study with stroke survivors (N=164) to test PRECiS in a large sample. Quantitative and qualitative data were collected on acceptability, feasibility and other psychometric properties of validity and reliability. PRECiS demonstrated good acceptability to stroke survivors and performed well psychometrically. Future validation work required for PRECiS is described in discussion chapter 4. Subject to further validation work, PRECiS may be particularly useful for pragmatic trials of cognitive rehabilitation after stroke.

The effectiveness of student focused school-based motivational interviewing : evidence emerging from current practice

Snape, Laura January 2016 (has links)
Motivational interviewing (MI) has been used extensively and often effectively in medical settings to support behaviour change in adults. There is emerging evidence that MI may also be a useful approach for working with young people in schools. This thesis investigated the effectiveness of MI in educational settings and is presented in three sections. The first paper is an evaluative systematic literature review examining the evidence for student-focused MI in educational settings. Eleven studies were included in the review, although just eight were identified as 'best evidence' and included in the synthesis. Overall there is evidence for the effectiveness of student-focused MI in the areas of behaviour, school-based motivation and academic achievement. However, a number of methodological weaknesses were identified in the existing literature, which provides clear pointers for future research. Previous research has highlighted the potential usefulness of MI when used as a therapeutic intervention with disaffected students. However, to date, there has been little published research investigating students' views on MI. The second paper aims to investigate students' views on an MI intervention. Three disaffected students took part in an individual MI intervention, which was delivered by three educational psychologists (EPs). Semi-structured interviews were used to obtain the students' views, immediately after the intervention and again at a follow-up interview three months later. The results indicated that students were enthusiastic about the intervention and most perceived that there had been a positive impact on their learning motivation and classroom behaviour. However, these results were not consistent with questionnaire responses and two of the students experienced exclusions around the time of the intervention. The implications of these ambiguous findings are discussed in relation to the use of therapeutic interventions by EPs and the possible factors that are crucial to the success of MI interventions. The third paper provides a critical appraisal of the overall research process, including implications of the work, wider context of the research and dissemination of evidence to professional practice.

Mapeamento das evidências das revisões sistemáticas de oftalmologia da base de dados Cochrane. [dissertação]. Botucatu, SP: Faculdade de Medicina, Universidade Estadual Paulista; 2018. Justificativa e objetivos: A Colaboração Cochrane visa oferecer, por meio da publicação de revisões sistemáticas, informações atualizadas, objetivas e com evidências consistentes para a prática clínica e para o estabelecimento de políticas de saúde. Entretanto, verifica-se, frequentemente, uma inconsistência de evidências e incapacidade de gerar recomendações. O objetivo desse estudo foi analisar as revisões sistemáticas do Grupo Oftalmologia da Colaboração Cochrane e mapear sua utilidade para a prática clínica e para a pesquisa científica. Método: Realizou-se estudo transversal com análise de todas as revisões sistemáticas publicadas no Grupo Oftalmologia da Colaboração Cochrane até maio de 2018, verificando-se qual o tipo de recomendação para a prática clínica e para a pesquisa científica, por meio da análise das conclusões de seus autores. Além disso, computou-se o número de ensaios clínicos e meta-análises por revisão sistemática e por subespecialidade, por ano. Resultados: 202 revisões foram obtidas no período. Evidências que apoiam a intervenção, com recomendação para a realização de mais estudos ou sem recomendação para mais estudos: 36,3% [IC 95% 36,2-36,4] e 5,0% [IC 95% 4,8-5,1], respectivamente. Evidências contrárias à intervenção, com recomendação para realização de mais estudos ou sem recomendação para mais estudos: 3,0% [IC 95% 2,8-3,1] e 3,5% [IC 95% 3,3-3,6], respectivamente. Ausência de evidências, com recomendação para a realização de mais estudos ou sem recomendação para mais estudos: 51,2% [IC 95% 55,1-55,3] e 1% [IC 95% 0,9-1,1], respectivamente. Do total, 90,5% das revisões sugerem a realização de mais estudos independentemente dos resultados obtidos. O número médio de ensaios clínicos nas revisões foi de 7,4, variando entre zero e 137, e o número médio de meta-análises foi igual a 3,1, variando entre zero e 26. Conclusão: A maioria das revisões sistemáticas do Grupo de Oftalmologia da Cochrane apresenta insuficiência ou ausência de evidências para recomendar determinada intervenção na prática clínica e recomenda a realização de novos estudos clínicos controlados e aleatorizados. / Bissoli SFR. Mapping of the evidences of systematic reviews of Ophthalmology Cochrane database. [dissertation]. Botucatu, SP: Botucatu Medical School, State University of São Paulo 2018. Rationale and objectives: The Cochrane Collaboration aims to provide, through the publication of systematic reviews, up-to-date, objective information and with consistent evidence for clinical practice and for the establishment of health policies. However, there is often an inconsistency of evidence and inability to generate recommendations. The objective of this study was to analyze the systematic reviews of the Cochrane Collaboration Ophthalmology Group and to map its usefulness to clinical practice and to scientific research. Methods: A cross-sectional study was carried out with an analysis of all the systematic reviews published in the Ophthalmology Group of the Cochrane Collaboration until May 2018, confirming the type of recommendation for clinical practice and for scientific research, through analysis of the conclusions of its authors. In addition, we counted the number of clinical trials and meta-analyzes by systematic review and by subspecialty, per year. Results: 202 revisions were obtained in the period. Evidence that supports the intervention, with recommendation for further studies: 36.3% [CI 95% 36.2-36.4] or no recommendation for further studies: 5.0% [CI 95% 4.8-5.1]. Evidence contrary to intervention, with recommendation for further studies 3.0% [CI 95% 2.8-3.1] or no recommendation for further studies 3.5% [CI 95% 3.3-3.6). Absence of evidence, with recommendation for further studies: 51.2% [CI 95% 55.1-55.3] or no recommendation for further studies 1% [CI 95% 0.9-1.1] . Of the total, 90.5% of the reviews suggest further studies regardless of the results obtained. The mean number of clinical trials in the reviews was 7.4 (ranging from zero to 137), and the mean number of meta-analyzes was 3.1 (ranging from zero to 26).Conclusion: Most systematic reviews of the Cochrane Ophthalmology Group show insufficiency or lack of evidence to recommend a particular intervention in clinical practice and recommends further controlled and randomized clinical trials.

Doença periodontal é fator de risco para parto prematuro e bebê de baixo peso?: revisão sistemática / Is periodontal disease a risk factor to preterm and low birth weight?: systematic review

Raquel Florêncio da Silva 28 March 2008 (has links)
O objetivo desta revisão sistemática foi analisar os estudos que relacionam doença periodontal e nascimento prematuro e baixo peso, verificando o efeito da doença periodontal materna no desfecho da gestação. Foi realizada pesquisa nas seguintes bases de dados: PubMed, Scielo e LILACS até Dezembro de 2007. A revisão sistemática foi conduzida de forma a identificar os estudos capazes de preencher os critérios de inclusão, apresentando aspectos clínicos, microbiológicos e radiográficos da doença periodontal, assim como os desfechos da gestação, ou seja, nascimento prematuro e baixo peso. Foram então selecionados 35 (trinta e cinco) artigos, sendo 9 (nove) coorte, 16 (dezesseis) casos controles, e 10 (dez) ensaios clínicos. A associação entre a doença periodontal materna e o nascimento de bebê prematuro com baixo peso foi encontrada em 26 (vinte e seis) estudos: 7 (sete) coorte, 11 (onze) casos controles e 8 (oito) ensaios clínicos. Não foi possível realizar uma meta-análise devido à grande heterogeneidade entre os estudos, particularmente no que se refere aos métodos de mensuração da doença periodontal. Um melhor controle em relação aos fatores de confusão também permitiria uma confiança maior nos resultados e conclusões apresentadas. Ainda não é possível ter conclusões adequadas do real efeito da doença periodontal sobre os desfechos da gestação devido a limitações nas metodologias dos presentes estudos. Portanto, a evidência da relação da doença periodontal com o nascimento de bebê prematuro e baixo peso é limitada. Ainda existe a necessidade de novos e bem desenhados estudos observacionais e de intervenção, que possam confirmar o que até agora é visto apenas como uma possível associação, explorando a validade dessas possíveis associações em diferentes populações e controlando adequadamente as variáveis de confusão. / The objective of this systematic review was to analyse the studies that relate the periodontal disease and the preterm and low birth weight deliveries, assessing the effect of the maternal periodontal disease in the pregnancy outcome. A research was conducted in the following databases: PubMed, Scielo and LILACS until December 2007. The systematic review was undertaken to identify the researches that met the inclusion criterias, addresssing aspects of periodontal disease: clinical, radiographic, microbiological and immunological, and pregnancy outcomes, like preterm low birth weight as well. In that case, 35 (thirty five) studies were selected, 9 (nine) cohort, 16 (sixteen) case controls, and 10 (ten) clinical trials. The association between maternal periodontal disease and preterm low birth weight was found in 26 (twenty six) studies: 7 (seven) cohort, 11 (eleven) case controls and 8 (eight) clinical trials. A meta-analysis was not performed due to the extensive and clear heterogenity of the studies, particulary regarding the periodontal disease measures. An adequate control for confounders would permit results and conclusions more reliable. It is not possible to know the real effect of the periodontal disease in the pregnancy outcomes until now, because of the methodology limitations of the current studies. Therefore, the evidence of the relation of the periodontal disease with the preterm low birth weight is limited. There is a need for new and well designed observational and interventional studies to confirm, what so far is only a possible association, to explore the validity of the association in different populations, correctly control for confounders.

No. of bitstreams: 1 2014 - Thiene Salazar Livio de Moraes.pdf: 2466223 bytes, checksum: 10b082d56f8727cf87f75df80791376b (MD5) Previous issue date: 2014-04-30 / Adjustment disorder is a diagnostic criterion associated with stress, which can occur during or after the occurrence of one or more stressful situations. It is a clinical condition which impairs the performance and social functioning and / or occupational functioning of the individual. However, it is noticed that the scientific studies on this topic are scarce. This master?s dissertation investigates the treatment kinds of Adjustment Disorder through a literature review and his prevalence among university students. Thus, this work is presented through two articles. The first is a systematic review of scientific literature of the articles about treatments for the Adjustment Disorder, published in the virtual library collections PsychInfo and PubMed / Medline. The result showed that, among the articles selected through some criteria, none is of Brazilian origin; all are from other countries, and most of the European continent. Therapies indicated in the studies were classified as psychotherapy, pharmacotherapy and herbal medicine. The second article focuses on the mental health of college students at the Universidade Federal Rural do Rio de Janeiro - Serop?dica. The study estimates the occurrence of the Adjustment Disorder among undergraduate students of the UFRRJ and detected the stressors preceding through a quantitative cross search, into a sample of 635 subjects. The results revealed that 19.4% of students matched the diagnostic criteria for the disorder Adaptation, according to the Inventory Valuation Adjustment Disorder (Self Report of the assessment of Adjustment Disorder) and 45.6 % showed susceptibility to development of psychopathological symptoms. Therefore, it is concluded that the mental health of the students in Brazilian universities, especially those that are located far from urban centers, requires scientific attention. Moreover, it is observed that little scientific attention has been given to Adjustment Disorder has collaborated that information on its prevalence in the general population and in specific populations as well as its diagnosis and its treatment remain scarce and inaccurate. / Transtorno de Adapta??o ? um crit?rio diagn?stico associado ao estresse, que pode se manifestar ap?s ou durante a ocorr?ncia de uma ou mais situa??es estressantes. ? um quadro cl?nico que entrava o desempenho e o funcionamento social e/ou ocupacional do indiv?duo. No entanto, percebe-se que os estudos cient?ficos sobre esse tema ainda s?o escassos. Esta disserta??o de mestrado se prop?s a investigar o Transtorno de Adapta??o a partir de uma revis?o de literatura, em torno dos tipos de tratamento e de sua preval?ncia entre estudantes universit?rios. Desse modo, esse trabalho ? apresentado atrav?s de dois artigos. O primeiro trata de uma revis?o sistem?tica da literatura cient?fica no que tange os artigos sobre tratamentos indicados para o Transtorno de Adapta??o, publicados nos acervos bibliogr?ficos virtuais Psycinfo e Pubmed/Medline. O resultado obtido mostrou que, dentre os artigos selecionados a partir dos crit?rios estabelecidos, nenhum ? de origem brasileira; todos s?o oriundos de outros pa?ses, sendo a maior parte do continente Europeu. As terapias indicadas nos estudos foram classificadas como Psicoterapia, Farmacoterapia e Fitoterapia. O segundo artigo enfoca a sa?de mental dos estudantes universit?rios da Universidade Federal Rural do Rio de Janeiro do campus Serop?dica. O trabalho estimou a ocorr?ncia do Transtorno de Adapta??o entre universit?rios da UFRRJ e detectou os fatores estressantes precedentes a ele, atrav?s de uma pesquisa Quantitativa Transversal, em uma amostra de 635 sujeitos. Os resultados revelaram que 19,4% dos alunos corresponderam aos crit?rios para o quadro de Transtorno de Adapta??o, segundo o Invent?rio de Avalia??o de Transtorno de Adapta??o (Self Report of the assessment of Adjustment disorder) e 45,6% demonstraram suscetibilidade ao desenvolvimento de sintomas psicopatol?gicos. Sendo assim, conclui-se que a sa?de mental dos graduandos das universidades brasileiras, principalmente naquelas que est?o localizadas distantes dos centros urbanos, requer aten??o do campo cient?fico. Al?m disso, observa-se que a pouca aten??o cient?fica dada ao Transtorno de Adapta??o tem corroborado para que informa??es sobre sua preval?ncia na popula??o geral e em popula??es espec?ficas, seu diagn?stico e seu tratamento continuem escassos e imprecisos.
