A segurança do paciente cirúrgico é problemática complexa e desafiadora em âmbito global. A presente pesquisa teve como objetivos (a) analisar as evidências disponíveis na literatura sobre o processo de implementação da lista de verificação de segurança cirúrgica da Organização Mundial da Saúde na prática dos serviços de saúde, e (b) analisar o processo de implementação e o uso diário da lista de verificação de segurança cirúrgica, segundo o relato de enfermeiros que atuavam em unidades de centro cirúrgico de hospitais de duas cidades localizadas no estado do Paraná. A pesquisa foi conduzida em duas fases: revisão integrativa e estudo descritivo. A busca dos estudos primários foi realizada nas bases de dados PubMed, CINAHL e LILACS. A amostra da revisão integrativa foi composta de 27 pesquisas agrupadas em três categorias, a saber: processo de implementação: estratégias para introdução da lista de verificação de segurança cirúrgica nos serviços de saúde (n=15); processo de implementação: estratégias para otimização do uso da lista de verificação de segurança cirúrgica nos serviços de saúde (n=9) e facilitadores e barreiras para implementação da lista de verificação de segurança cirúrgica nos serviços de saúde (n=3). A condução da revisão integrativa possibilitou compreender o processo de implementação da lista, as diferentes estratégias utilizadas para sua implantação, aspectos da implementação considerados bem-sucedidos ou pouco exitosos no alcance dos resultados esperados, facilitadores e barreiras deste processo. O estudo descritivo foi realizado em 25 hospitais de duas cidades que compõem a mesorregião do Norte Central Paranaense (Londrina e Maringá). Os participantes foram 91 enfermeiros que atuavam em centro cirúrgico dos hospitais selecionados. Para a coleta de dados elaborou-se dois instrumentos, os quais foram submetidos à validação aparente e de conteúdo. Os resultados evidenciaram que, na maioria dos hospitais investigados, a lista de verificação de segurança cirúrgica foi implementada, sendo que, para a maioria dos participantes, as estratégias adotadas na introdução da lista foram o planejamento prévio conduzido pelos enfermeiros, a adaptação com predominância do uso no formato impresso e programa educacional. Com relação ao uso diário da lista, a maioria dos enfermeiros apontou a utilização inadequada desta prática nos seguintes aspectos: adesão parcial ao uso pela equipe cirúrgica, diferença de adesão entre as etapas de checagem e entre as categorias profissionais e condutas inadequadas da equipe cirúrgica na checagem da lista em sala cirúrgica (equipe incompleta, desatenta e sem participação ativa de seus membros). Para a maioria dos participantes, o uso da lista trouxe benefícios ou tem potencial para produzir efeitos benéficos para o paciente, equipe cirúrgica e serviço de saúde. As evidências geradas trazem subsídios para os enfermeiros e demais profissionais de saúde na elaboração de protocolos relativos ao processo de implementação ou uso diário da lista mais adequados e compatíveis com as especificidades estruturais e organizacionais dos serviços de saúde nacionais, com o propósito de viabilizar a integração desta ferramenta no processo de trabalho, melhorar a adesão da equipe e alcançar os melhores resultados em prol da segurança do paciente / Surgical patient safety is a complex and challenging problem at the global level. This study aimed to analyze (a) the available evidence in the literature on the process of implementation of the surgical safety checklist of the World Health Organization in the practice of health services, and (b) the implementation process and the daily use of the surgical safety checklist, according to the report of nurses working in surgical center units of hospitals of two cities located in the state of Paraná. The research was conducted in two phases: integrative review and descriptive study. The search for primary studies was carried out in PubMed, CINAHL and LILACS databases. The sample of the integrative review consisted of 27 studies grouped into three categories, namely: implementation process: strategies for the introduction of the surgical safety checklist in the health services (n = 15); implementation process: strategies to optimize the use of the surgical safety checklist in health services (n = 9) and facilitators and barriers to the implementation of the surgical safety checklist (n = 3). Conducting the integrative review made it possible to understand the process of implementing the list, the different strategies used for its implementation, aspects of implementation considered successful or not very successful in achieving the expected results, facilitators and barriers of this process. The descriptive study was carried out in 25 hospitals of two cities that make up the mesoregion of Northern Central of Paraná state (Londrina and Maringá). Participants were 91 nurses who worked in the surgical center of the selected hospitals. For the data collection, two instruments were elaborated, which were submitted to the apparent validation and content. The results showed that, in most of the hospitals investigated, the surgical safety checklist was implemented, and, for most of the participants, the strategies adopted in the introduction of the list were the previous planning conducted by the nurses, the adaptation with predominance of the use in the printed format and educational program. Regarding the daily use of the list, most of the nurses pointed out the inadequate use of this practice in the following aspects: surgical team\'s partial adherence to the use of it, difference in adherence between the check-up stages, and between the professional categories and inadequate behavior of the surgical team in checking the list in the surgical room (incomplete, inattentive team, and members not taking part actively). For most participants, using the list has brought benefits or can potentially produce beneficial effects for the patient, surgical team, and health service. The evidence generated provides subsidies for nurses and other health professionals in elaborating protocols related to the implementation process or daily use of the list more adequate and compatible with the structural and organizational specificities of the national health services, in order to make feasible the integration of this tool into the work process, to improve team adherence and to achieve the best results for patient safety

Nas últimas décadas, verificou-se diferenças nas classificações da World Health Organization (WHO) de 2001 e da European Organization for Research and Treatment of Cancer (EORTC) de 1997 para os linfomas cutâneos primários. Em 2005, representantes dessas classificações se reuniram e em consenso estabeleceram a classificação WHO-EORTC que foi adotada pela última classificação da WHO de 2008. O presente estudo visa a avaliar a aplicabilidade dessa nova classificação em casuística retrospectiva de um único centro de referência no diagnóstico e tratamento de linfomas cutâneos. Assim, todos os casos de linfoma cutâneo de células T, excluindo-se micose fungóide (MF) e síndrome de Sézary (SS), no período de 1986 a 2009, foram analisados em relação aos aspectos clínicos, histopatológicos e imunofenotípicos, incluindo-se a realização de novas reações imunoistoquímicas. Os casos foram, então, classificados de acordo com critérios estabelecidos na classificação WHO de 2008. Houve, assim, 33 casos de linfomas cutâneos de células T não-MF e não-SS, sendo 08 (24,2%) de linfoma cutâneo de grandes células anaplásicas, 05 (15,2%) de papulose linfomatóide, 06 (18,1%) de linfoma extranodal de células NK/T tipo nasal, 05 (15,2%) de neoplasia de células dendríticas plasmocitóides blásticas, 05 (15,2%) de linfoma/leucemia de células T do adulto e 04 (12,1%) de linfoma de células T periféricas, sem outra especificação. Portanto, a classificação WHO de 2008 é aplicável à maioria dos casos de linfoma cutâneo de células T não-MF e não-SS. Entretanto, permanecem casos não classificáveis, alguns dos quais com curso clínico agressivo / Recent years have witnessed differences between the World Health Organization (WHO) 2001 and the European Organization for Research and Treatment of Cancer (EORTC) 1997 classification systems of primary cutaneous lymphomas (PCLs). In 2005, a joint WHO-EORTC classification system for PCLs has been reached and was adopted by last WHO 2008 classification. This study was performed to assess the applicability of this new classification to a single referral center. All cutaneous T-cell lymphoma (CTCL) cases, excluding mycosis fungoides (MF) and Sezary syndrome (SS), who were referred from 1986 to 2009 were included. The clinical features, histological and immunohistochemical stainings were reviewed, and additional stains were performed as needed. The cases were then reclassified according to the WHO 2008 classification. There were 33 cases of non-MF and non-SS CTCL, included 08 (24.2%) CD30+ anaplastic large-cell lymphomas, 05 (15.2%) cases of lymphomatoid papulosis, 06 (18.1%) extranodal NK/T-cell lymphoma nasal type, 05 (15.2%) blastic plasmacytoid dendritic cell neoplasm, 05 (15.2%) adult T-cell lymphoma/leukemia and 04 (12.1%) peripheral T-cell lymphomas, unspecified. The new WHO 2008 classification is applicable to most nonMF and non-SS CTCL cases. However, there is still a substantial subset of T-cell PCLs which cannot be classified beyond the unspecified peripheral T-cell category, some of which may have an aggressive course

Foram revisados 568 TO, representando 3,8% do total das amostras de biópsia da região oral e maxilofacial. A idade média dos pacientes foi de 32,4 anos, com variação entre 3 e 83 anos e maior distribuição na 2ª e 3ª décadas de vida. A relação homen-mulher foi de 1:1.2 e a maioria dos pacientes tinha cor de pele branca (57,9%). Do total, 559 tumores localizavam-se no interior dos ossos gnáticos, 393 na mandíbula (70,3%) e 147 na maxila (26,3%), especialmente na região posterior e anterior, respectivamente. A distribuição dos 568 TO encontrados indicou 191 tumores odontogênicos queratocísticos, 174 ameloblastomas, 76 odontomas, 31 tumores odontogênicos císticos calcificantes, 26 mixomas/fibromixomas odontogênico, 13 cementoblastomas, 11 fibromas odontogênicos, 10 tumores odontogênicos adenomatóides, 7 fibro-odontomas ameloblásticos, 6 tumores odontogênicos epiteliais calcificantes, 4 fibromas ameloblásticos, 3 tumores odontogênicos escamosos, 3 tumores dentinogênicos de células fantasmas, e 6 carcinomas odontogênico, incluindo 3 carcinomas espinocelulares intraósseos primários, 2 carcinomas ameloblásticos e 1 carcinoma odontogênico de células claras. Foram ainda encontrados 7 tumores odontogênicos não-classificáveis. Os TO são lesões incomuns nesta população brasileira, em que as lesões malignas são extremamente raras. O paciente é mais freqüentemente do gênero feminino, de cor de pele branca entre 10 e 29 anos de idade, e as lesões envolvem principalmente a região posterior da mandíbula como uma imagem radiolúcida unilocular de limites precisos. A freqüência relativa e a distribuição das informações demográficas, clínicas, radiográficas e histopatológicas dos subtipos histológicos mostraram semelhanças com a encontrada na literatura revisada de diferentes países, excluindo-se o tumor odontogênico queratocístico. / Abstract: The aim of this study was to evaluate the relative frequency and demographical, clinical, radiological and pathological features of a series of odontogenic tumors (OT) from the files of 3 oral histopathology services and 1 general histopathology service from the city of Rio de Janeiro in the period from 1970 to 2008, after reviewing their final diagnosis according to the diagnostic criteria elaborated by the World Health Organization in 2005. A total of 568 OT was reviewed, representing 3,8% of all oral and maxillofacial biopsy samples. Mean age of the patients was 32.4 years-old, ranging from 3 to 83 years, with most cases in the 2nd and 3rd decades of life. The male-female ratio was 1:1.2 and most patients were Caucasians (57.9%). From the total, 559 OT were centrally located on maxillary bones, being 393 in the mandible (70.3%) and 147 in the maxilla (26.3%), especially in the posterior and anterior regions, respectively. Distribution of the 568 OT revealed 191 keratocystic odontogenic tumors, 174 ameloblastomas, 76 odontomas, 31 calcifying cystic odontogenic tumors, 26 odontogenic myxomas/fibromyxomas, 13 cementoblastomas, 11 odontogenic fibromas, 10 adenomatoid odontogenic tumors, 7 ameloblastic fibro-dontomas, 6 calcifying epithelial odontogenic tumors, 4 ameloblastic fibromas, 3 squamous odontogenic tumors, 3 dentinogenic ghost cell tumors and 6 odontogenic carcinomas, including 3 cases of primary intraosseous squamous cell carcinomas, 2 ameloblastic carcinomas and 1 clear cell odontogenic carcinoma. Also, 7 OT were considered non-classifiable. OT are uncommon lesions in this Brazilian population, and malignant lesions are extremely rare. The patient is more commonly female, Caucasian, between 10 and 29 years-old, and the lesions occur in the posterior mandible as a well-defined unilocular radiolucency. The relative frequency and distribution of the demographical, clinical, radiological and pathological information obtained from each histological subtype showed similarities to the revised literature from different countries, excluding the keratocystic odontogenic tumor. / Doutorado / Patologia / Doutor em Estomatopatologia

Institution spécialisée du système des Nations Unies créée à la sortie de la Seconde guerre mondiale, l'Organisation mondiale de la santé (OMS) s'est vu confiée, par l'article premier de sa Constitution, le but « d'amener tous les peuples au niveau de santé le plus élevé possible ». Pour atteindre cet objectif, les États membres lui ont conféré vingt-deux fonctions dont une normative. Cette dernière lui permet, en théorie, d’adopter à la fois des instruments de santé non contraignants et d'autres contraignants. L'étendue du champ d'application de cette fonction permet à l'OMS d'élaborer des normes au contenu très divers et varié dès lors qu'elle agit dans le cadre de son objectif sanitaire. Parallèlement, en raison de difficultés internes, propres à son organisation régionalisée et à une concurrence externe accrue par la multiplication d'acteurs de santé mondiale, l'OMS est à un tournant de son histoire comme en atteste l'envergure de la réforme qui est toujours en cours depuis 2010. Dans ce contexte, il s'agit de comprendre et d'analyser l'influence du rôle normatif de l'OMS dans les systèmes de santé nationaux. D'abord, une évaluation de son autorité normative, qui apparaît affaiblie, est proposée afin de présenter des évolutions pour la renforcer et ainsi améliorer la protection de la santé mondiale au sein d'un droit international de la santé consolidé. Ensuite, l'étude approfondie de son activité normative est envisagée pour délimiter la conception de la norme de l'OMS par le prisme de son efficacité. L'objectif in fine est de proposer une réflexion sur l'avenir du rôle normatif de l'OMS. / The World health organization (WHO), as a specialized agency, was created, after the Second world war with the objective of, according to article 1 of its Constitution, the "attainment by all peoples of the highest possible level of health”. For that purpose, the WHO was granted twenty two functions by the Member States including a normative one. This normative function allows, in theory, the WHO to adopt both binding and non binding health instruments. The extent of the scope of this function offers a wide and diverse content to theses norms with the only limit that it pursues a health purpose. At the same time, the WHO shows internal difficulties, in part, due to its regional structure and overall lack of financing. Further, the increase number and diversity of actors of global health result in potential external competition with the WHO. The reform initiated in 2010 and still ongoing proves that the WHO is a turning point in its history. In this context, this research seeks to understand and analyze the influence of the normative role of the WHO on national health systems. First, we study the normative authority of the WHO which appears weakened. With the objective of increasing health protection based on a reinforced global health law paradigm, our proposals aim at strengthening the normative authority of WHO. Then, our in-depth analysis of the normative activity of the WHO allows to the define the conception of norm by the WHO using effectiveness as our analytical frame. Finally, this research offers an opportunity to reflect on the future of the normative role of the WHO.

The CIDI is a fully standardised diagnostic interview designed for assessing mental disorders based on the definitions and criteria of ICD-1Oand DSM-IlI-R. Field trials with the CIDI have been conducted in 18 centres around the world, to test the feasibility and reliability of the CIDI in different cultures and settings, as well as to test the inter-rater agreement for the different types of questions used. Of 590 subjects interviewed across all sites and rated by an interviewer and observer, 575 were eligible for analysis. The CIDI was judged to be acceptable for most subjects and was appropriate for use in different kinds of settings. Many subjects fulfilled criteria for more than one diagnosis (lifetime and six-month). The most frequent lifetime disorders were generalised anxiety, major depression, tobacco use disorders, and agoraphobia. Percentage agreements for all diagnoses were above 90% and the kappa values were all highly significant. No significant numbers of diagnostic disconcordances were found with lifetime, six-month, and four-week time frames.

The CIDI is a fully standardised, structured interview for the assessment of psychiatric disorders according to DSM-II-R and proposed ICD-10 criteria. The development of this interview has been the collaborative effort of researchers from 18 sites around the world. In a field trial to test the cross-cultural acceptability and reliability of the questions, there was found to be high acceptance and excellent reliability for the substance use questions, problems with the lengthy alcohol section, and difficulties translating relevant substance use concepts into different languages. There is therefore room for further improvement in the substance-related questions. There proved to be differences between ICD-10 and DSM-III-R regarding substance abuse and dependence disorders.

My thesis is focused on the composition and countries' representation in the professional staff of the World Health Organization. The thesis will analyse the overrepresentation and underrepresentation of the WHO's member states and explain possible patterns in the staff. The thesis will focus on the relationship between the number of Member State's professional staff in the WHO and the state's GDP growth, expenditure on education and population size. My thesis aims to research the characteristics of staff's composition in the WHO. I will analyse professional staff structure and apply the Principal-Agent theoretical framework. The research will show how the state's representation of member states changed over time and see also the gender composition of the Secretariat. The timeline of this work is from 1999 till 2019.

>Magister Scientiae - MSc / Background: Despite the effort of scientific research on HIV therapies and to reduce the rate of HIV infection, AIDS still remains one of the major causes of death in the world and mostly in Sub-Saharan Africa. To date, neither a cure, nor an HIV vaccine had been found and the disease can only be managed by using High Active Antiretroviral Therapy (HAART) if detected early. The need for an effective early diagnostic and non-toxic therapeutic treatment has brought about the necessity for the discovery of additional HIV diagnostic methods and treatment regimens to lower mortality rates. Antimicrobial Peptides (AMPs) are components of the first line of defence of prokaryotes and eukaryotes and have been proven to be promising therapeutic agents against HIV. Methods: With the utility of computational biology, this work proposes the use of profile search methods combined with structural modelling to identify putative AMPs with diagnostic and anti-HIV activity. Firstly, experimentally validated anti-HIV AMPs were retrieved from various publicly available AMP databases, APD, CAMP, Bactibase and UniprotKB and classified according to super-families. Hidden Markov Model (HMMER) and Gap Local Alignment of Motifs (GLAM2) profiles were built for each super-family of anti- HIV AMPs. Putative anti-HIV AMPs were identified after scanning genome sequence databases using the trained models, retrieved AMPs and ranked based on their E-values. The 3-D structures of the 10 peptides that were ranked highest were predicted using 1-TASSER. These peptides were docked against various HIV proteins using PatchDock and putative AMPs showing highest affinity and having the correct orientation to the HIV -1 proteins gp 120 and p24 were selected for future work so as to establish their function in HIV therapy and diagnosis. Results: The results of the in silica analysis showed that the constructed models using the HMMER algorithm had better performances compare to that of the models built by the GLAM2 algorithm. Furthermore, the former tool has better statistical and probability explanation compared to the latter tool. Thus only the HMMER scanning results were considered for further study. Out of 1059 species scanned by the HMMER models, 30 putative anti-HIV AMPs were identified from genome scans with the family specific profile models after elimination of duplicate peptides. Docking analysis of putative AMPs against HIV proteins showed that from the 10 best performing anti-HIV AMPs with the highest Escores, molecules 1,3, 8 and 10 firmly binds the gp120 binding pocket at the VIN2 domain and at the point of interaction between gp120 and T cells, with the 1st and 3rd highest scoring anti-HIV AMPs having the highest binding affinities. However, all 10 putative anti-HIV AMPs bind to the N-terminal domain of p24 with large surface interaction, rather than the C-terminal. Conclusion: The in silica approach has made it possible to construct computational models having high performances, and which enabled the identification of putative anti-HIV peptides from genome sequence scans. The in silica validation of these putative peptides through docking studies has shown that some of these AMPs may be involved in HIV/AIDS therapeutics and diagnostics. The molecular validation of these findings will be the way forward for the development of an early diagnostic tool and as a consequence initiate early treatment. This will prevent the invasion of the immune system by blocking the VIN2 domain and thus designing of a successful vaccine with broad neutralizing activity against this domain.

Cardiovascular diseases (CVDs) are a leading cause of death worldwide, emphasizing the need for advanced and effective intervention and treatment measures. Hypertension, a significant risk factor for CVDs, is characterized by reduced vascular compliance in arterial vessels. There is a significant rise in interest in exploring the viscoelastic properties of arteries in the last few years, for the treatment of these diseases. This study aims to develop an experimental setup using 3D Printing Technology to test viscoelastic arterial models for the validation of a diagnostic device for cardiovascular diseases. The research investigates the selection of polymer-based materials that closely mimic the viscoelastic properties of arterial vessels. An experimental setup is designed and fabricated to perform mechanical tests on 3D-printed specimens. The study utilizes a mathematical model to describe the viscoelastic behavior of the materials. The model's predictions are validated using experimental data obtained from the mechanical tests. This study demonstrates the potential of 3D printing technology in fabricating specimens using elastic and flexible resin materials. These specimens closely replicate the mechanical properties of native arteries, offering a tangible platform for controlled mechanical testing. Stress relaxation tests on the3D printed specimens highlight the viscoelastic properties of fabricated materials, shedding light on their behavior under strain. The study goes further to model the mechanics of these materials, utilizing the Fractional Voigt model to capture the intricate balance between elastic and resistive behaviors under varying deformation levels. The results highlight the successful fitting of the Fractional Voigt model to the experimental data, confirming the viscoelastic behavior of the specimens. The obtained values of α and RMSE indicate a good representation of arterial mechanical properties within the viscoelastic arterial model, under different loading conditions. This research contributes to improving cardiovascular device validation and offers a practical and reliable alternative to invasive experiments. Future works include exploring different materials and conditions for arterial modeling and enhancing the precision and scope of the viscoelastic model. Overall, this study advances the understanding of cardiovascular biomechanics, contributing to the development of more effective diagnostic devices for cardiovascular diseases.

Vaccine Hesitancy is a critical public health issue that threatens global health security, increases rates of transmission of deadly diseases, and poses additional infectious risk to everyone. This dissertation uses records from the National Archives and Records Administration of the United States, National Archives of Mexico, World Health Organization, multiple Presidential Libraries, and an assortment of digital records to examine the historical roots of vaccine hesitancy. I argue that the choice to delay vaccination or outright refusal of vaccination often constitutes a form of political protest. This anti-vaccine sentiment has historically functioned as political protest that opposes American and Western presence in developing countries. Illustrative case studies of Pakistan and Mexico between 1947 and 1990 illustrate how the manner in which vaccines are distributed within the context of Cold War disease eradication campaigns can influence vaccine hesitancy. Horizontal vaccine programming in Mexico wherein vaccines were distributed using a robust, native public health infrastructure found more epidemiological success than Pakistani vaccination programs that relied on vertically-oriented, Western-led mass vaccination programming to mitigate the burden of infectious diseases including smallpox and polio. Rhetorical analysis of archival vaccine-related media in these countries also reflects the politicized nature of Cold War vaccine hesitancy. Additionally, this dissertation broadly considers the array of weaponry in the American diplomatic arsenal and compares the diplomatic utility of vertical mass vaccination campaigns with military assistance that was also provided to developing nations in the pursuit of American anti-communist goals in the midst of the Cold War. I argue that certain programmatic ambiguities in Cold War American Foreign Policy led to the production of a uniquely militarized form of American diplomacy. An examination of biosurveillance networks constructed to support the global eradication of smallpox and subsequently replicated to eradicate polio illustrate the long-standing historical intersection between public health programming and military force that underlie historical and modern vaccine hesitancy.
