Prevalence and risk factors for Toxoplasma gondii infection among pregnant and postpartum women attended at public healthcare facilities in the City of Niterói, State of Rio de Janeiro, Brazil

IntroductionTo determine the prevalence of immunoglobulin G (IgG) and immunoglobulin M (IgM) anti-Toxoplasma gondii antibodies among pregnant and postpartum women attended within the public healthcare system in Niterói, State of Rio de Janeiro, and to detect possible exposure factors associated with T. gondii infection in this population.MethodsIgM and IgG anti-T. gondii antibodies were investigated in 276 pregnant and 124 postpartum women by using the indirect immunofluorescence (IFAT) and immunoenzymatic assay (ELISA) techniques. The participants were selected by convenience sampling. All these 400 patients filled out a free and informed consent statement, answered an epidemiological questionnaire and were informed about the disease.ResultsAmong the 400 samples analyzed, 234 (58.5%) were reactive to IgG anti-T. gondii antibodies, according to the IFAT and/or ELISA assay. One pregnant woman was found to be reactive to IgM anti-T. gondii antibodies, with an intermediate IgG avidity test. Risk factor analysis showed that seropositivity was significantly associated (p<0.05) with age, contact with cats and presence of rodents at home. Through a logistic regression model, these associations were confirmed for age and contact with cats, while education at least of the high school level was found to be a protective factor.ConclusionsThe prevalence rate of IgG anti-T. gondii antibodies in the City of Niterói was high and the risk factors for infection detected after multivariate analysis were: age over 30 years, contact with cats and education levels lower than university graduate level.

Integration of speech-processing technologies into Activobank's client interaction process

This dissertation analyzes the possibilities of utilizing speech-processing technologies to transform the user experience of ActivoBank’s customers while using remote banking solutions. The technologies are examined through different criteria to determine if they support the bank’s goals and strategy and whether they should be incorporated in the bank’s offering. These criteria include the alignment with ActivoBank’s values, the suitability of the technology providers, the benefits these technologies entail, potential risks, appeal to the customers and impact on customer satisfaction. The analysis suggests that ActivoBank might not be in a position to adopt these technologies at this point in time.

Analysis of the detection coefficient for the association between leprosy and pregnancy in the integration region of Carajas, State of Para, Brazil

Introduction The association between leprosy and pregnancy is currently poorly understood and has been linked to serious clinical consequences. Methods A retrospective study between 2007 and 2009 was performed in the integration region of Carajás, Brazil on a population of pregnant lepers, with non-lepers of ages 12-49 years serving as the reference population. Results Twenty-nine pregnant lepers were studied during the study period. The detection rates (DRs) for the studied association were 4.7 in 2007, 9.4 in 2008, and 4.3 in 2009. Conclusions The Carajás region presented a medium pattern of endemicity during most of the study period, with a high DR found in 2008.

The integration of online advertising into social media

This study examined user-generated (UG) advertising in the context of social media networks. The focus was on how people, whether an expert in the area, a non-expert or a friend, influence the reader of the advertisement. Furthermore, the study analyzed how the certainty level of the UG advertisement influences the person viewing the ad. The study showed that for the friend source a high certainty message was more persuasive. However, regarding the certainty no significant results were found for the expert and non-expert. Further, the type of the source had a considerable impact on persuasion. Someone that we personally know (e.g., a friend) was rated most positive for all analyzes variables. This shows that with the rising usage of social media there are great opportunities for new effective advertising strategies that could include a new type of an endorser – friends.

Molecular analysis of methicillin-resistant Staphylococcus aureus dissemination among healthcare professionals and/or HIV patients from a tertiary hospital

Abstract INTRODUCTION: Methicillin-resistant Staphylococcus aureus (MRSA) is a nosocomial pathogen in community settings. MRSA colonized individuals may contribute to its dissemination; the risk of MRSA infection is increased in human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) patients, although the prevalence of colonization in this group is not well established. The present study addressed this issue by characterizing MRSA isolates from HIV/AIDS patients and their healthcare providers (HCPs) to determine whether transmission occurred between these two populations. METHODS: A total of 24 MRSA isolates from HIV-infected patients and five from HCPs were collected between August 2011 and May 2013. Susceptibility to currently available antimicrobials was determined. Epidemiological typing was carried out by pulsed-field gel electrophoresis, multilocus sequence typing, and Staphylococcus cassette chromosome (SCCmec) typing. The presence of heterogeneous vancomycin-intermediate Staphylococcus aureus (hVISA) and heterogeneous daptomycin-resistant Staphylococcus aureus (hDRSA) was confirmed by population analysis profile. Isolates characterized in this study were also compared to isolates from 2009 obtained from patients at the same hospital. RESULTS: A variety of lineages were found among patients, including ST5-SCCmecII and ST30-SCCmecIV. Two isolates were Panton-Valentine leukocidin-positive, and hVISA and hDRSA were detected. MRSA isolates from two HCPs were not related to those from HIV/AIDS patients, but clustered with archived MRSA from 2009 with no known relationship to the current study population. CONCLUSIONS: ST105-SCCmecII clones that colonized professionals in 2011 and 2012 were already circulating among patients in 2009, but there is no evidence that these clones spread to or between HIV/AIDS patients up to the 7th day of their hospitalization.

Estudo sobre o Grau de Integração de Organizações de Saúde – EGIOS II

RESUMO - O movimento de integração dos cuidados de saúde tem como objectivo a procura de modelos de prestação de cuidados mais compreensivos, integrados e continuados. A determinação do grau de integração de cuidados pode ser realizada a partir da percepção dos profissionais de saúde, sendo os inquéritos por questionários uma fonte comummente utilizada neste tipo de estudos. O presente estudo, designado por EGIOS II, tem como objetivos: a) determinar o grau de percepção de integração, dos profissionais das Unidades Locais de Saúde; b) comparar a percepção do grau de integração dos profissionais entre 2010 e 2015; c) comparar a percepção do grau de integração dos profissionais que trabalham nas Unidades Locais de Saúde e em instituições não organizadas em Unidades Locais de Saúde; e d) identificar as áreas de maior e menor percepção de integração. O instrumento de recolha de dados utilizado, foi um inquérito por questionário, que pretende avaliar a percepção do grau de integração dos profissionais de acordo com as dimensões clínica, informação, normativa, administrativa, financeira e sistémica, em 53 itens. O inquérito foi estruturalmente adaptado do Health System Integration Study, tendo apresentado validade e fiabilidade. O inquérito foi aplicado em 22 instituições, a nível nacional, Unidades Locais de Saúde e a Centros Hospitalares / Hospitais e Agrupamentos de Centros de Saúde. A caraterização EGIOS II dividiu-se em quatro fases: preparação e envio dos ofícios; identificação dos interlocutores; envio dos inquéritos; e avaliação dos resultados. O inquérito apresentou uma taxa de resposta de 27%, representando 2085 respostas ao inquérito. Pode afirmar-se que globalmente o estudo apresenta representatividade estatística, com um intervalo de confiança de 95%. Os resultados indicam que os profissionais das Unidades Locais de Saúde em 2015 reportam maiores níveis de percepção de integração, quando comparados os dados com o estudo de 2010. Acrescenta-se que os profissionais das Unidades Locais de Saúde têm um maior grau de percepção de integração, do que os profissionais dos Centros Hospitalares / Hospitais e Agrupamentos de Centros de Saúde, não organizados em ULS. As dimensões administrativa, financeira e clínica são as que apresentam um menor grau de percepção de integração e as dimensões normativa e informação uma maior percepção de integração. Os órgãos de administração e órgãos de gestão intermédia apresentam uma percepção de integração superior comparativamente aos médicos e enfermeiros dos serviços hospitalares e cuidados de saúde primários. Foram identificadas nove recomendações que poderão servir como base para um plano de ação subsequente do presente estudo ou para aplicação em futuros estudos. Este estudo pode auxiliar no diagnóstico de problemas e barreiras da integração de cuidados, em que serviços atuar e ainda, identificar quais as estratégias e processos a priorizar de forma a melhorar a integração de cuidados de saúde.

Análise comparativa das readmissões hospitalares nas Unidades Locais de Saúde (ULS) e nos Hospitais

RESUMO - Introdução: Os modelos organizacionais de saúde baseados na gestão integrada de cuidados têm permitido melhorar os resultados em saúde. A taxa de readmissão hospitalar (um indicador de resultados) tem diminuído nas instituições que adotaram aquele modelo de gestão. Em Portugal, a criação das Unidades Locais de Saúde, representa a adoção de um modelo baseado na gestão integrada entre os cuidados de saúde hospitalares, primários e continuados, pelo que importa comparar a taxa de readmissões hospitalares entre os hospitais com esse modelo e os restantes Hospitais. Metodologia: Determinaram-se as readmissões não planeadas a 30 dias nos hospitais públicos portugueses do Continente durante 2013, segundo a metodologia do Centers for Medicare and Medicaid Service, que usa um algoritmo que identifica as readmissões que são habitualmente planeadas e podem ocorrer no prazo de 30 dias após a alta hospitalar. Foi calculada a taxa anual de readmissão por tipo de hospital e a sua frequência por género, faixa etária e para indivíduos com insuficiência cardíaca, doença pulmonar obstrutiva crónica, diabetes mellitus e hipertensão arterial. Resultados: Dos 692.211 episódios de internamento de 2013, 6,0% corresponderam a readmissões hospitalares não planeadas a 30 dias. Os episódios de internamento nas Unidades Locais de Saúde foram 72.725, sendo 6,6% readmitidos. Nos restantes Hospitais foram 619.486, sendo 6,0% readmitidos. A taxa de readmissão registada nos indivíduos do sexo masculino foi superior à do sexo feminino nas Unidades Locais de Saúde (7,6% vs. 6,0%) e nos restantes Hospitais (6,7% vs. 5,4%), não sendo esta diferença estatisticamente significativa (p> 0,05). Foram identificadas diferenças estatisticamente significativas (p <0,05) nas taxas de readmissão por faixa etária, sendo as pessoas com 65 anos ou mais as que apresentaram a maior taxa de readmissão nas Unidades Locais de Saúde (10,3%) e nos restantes Hospitais (10,0%). Quando analisadas as readmissões por patologia, nas Unidades Locais de Saúde os doentes com doença pulmonar obstrutiva crónica foram os que apresentaram a maior taxa de readmissão (17,5%) e os doentes com insuficiência cardíaca os que apresentaram a maior taxa de readmissão para os restantes Hospitais (16,4%). Conclusão: Em termos gerais, a frequência das readmissões nas Unidades Locais de Saúde é superior à dos restantes Hospitais. Os resultados obtidos podem indicar dificuldades na operacionalização do modelo de gestão adotado pelas Unidades Locais de Saúde, nomeadamente falhas na coordenação dos cuidados entre os diferentes níveis de prestação de cuidados.

Electro-Optical/Infrared sensor turret integration on an aircraft - structural im-pact on LOCKHEED MARTIN C-130H and design methodology

The growing need to patrol and survey large maritime and terrestrial areas increased the need to integrate external sensors on aircraft in order to accomplish those patrols at increasingly higher altitudes, longer range and not depending upon vehicle type. The main focus of this work is to elaborate a practical, simple, effective and efficient methodology for the aircraft modification procedure resulting from the integration of an Elec-tro-Optical/Infra-Red (EO/IR) turret through a support structure. The importance of the devel-opment of a good methodology relies on the correct management of project variables as time, available resources and project complexity. The key is to deliver a proper tool for a project de-sign team that will be used to create a solution that fulfils all technical, non-technical and certi-fication requirements present in this field of transportation. The created methodology is inde-pendent of two main inputs: sensor model and aircraft model definition, and therefore it is in-tended to deliver the results for different projects besides the one that was presented in this work as a case study. This particular case study presents the development of a structure support for FLIR STAR SAPHIRE III turret integration on the front lower fuselage bulkhead (radome) of the LOCKHEED MARTIN C-130 H. Development of the case study focuses on the study of local structural analysis through the use of Finite Element Method (FEM). Development of this Dissertation resulted in a cooperation between Faculty of Science and Technology - Universidade Nova de Lisboa and the company OGMA - Indústria Aeronáutica de Portugal

Healthcare- Associated infections: An analysis of costs in a Portuguese Hospital

Hospital-acquired infections (HAIs) delay healing, prolong Hospital stay, and increase both Hospital costs and risk of death. This study aims to estimate the extra length of stay and mortality rate attributable to each of the following HAIs: wound infection (WI); bloodstream infection (BSI); urinary infections (UI); and Hospital-acquired pneumonia (HAP). The study population consisted of patients discharged in CHLC in 2014. Data was collected to identify demographic information, surgical operations, development of HAIs and its outputs. The study used regressions and a matched strategy to compare cases (infected) and controls (uninfected). The matching criteria were: age, sex, week and type of admission, number of admissions, major diagnostic category and type of discharge. When compared to matched controls, cases with HAI had a higher mortality rate and greater length of stay. WI related to hip or knee surgery, increased mortality rate by 27.27% and the length of stay by 74.97 days. WI due to colorectal surgery caused an extra mortality rate of 10.69% and an excess length of stay of 20.23 days. BSI increased Hospital stay by 28.80 days and mortality rate by 32.27%. UI caused an average additional length of stay of 19.66 days and risk of death of 12.85%. HAP resulted in an extra Hospital stay of 25.06 days and mortality rate of 24.71%. This study confirms the results of the previous literature that patients experiencing HAIs incur in an excess of mortality rates and Hospital stay, and, overall, it presents worse results comparing with other countries.

Integration of geometric consistency contributory factors in three-leg junctions collision prediction models of Portuguese two-lane national highways

This paper aims at developing a collision prediction model for three-leg junctions located in national roads (NR) in Northern Portugal. The focus is to identify factors that contribute for collision type crashes in those locations, mainly factors related to road geometric consistency, since literature is scarce on those, and to research the impact of three modeling methods: generalized estimating equations, random-effects negative binomial models and random-parameters negative binomial models, on the factors of those models. The database used included data published between 2008 and 2010 of 177 three-leg junctions. It was split in three groups of contributing factors which were tested sequentially for each of the adopted models: at first only traffic, then, traffic and the geometric characteristics of the junctions within their area of influence; and, lastly, factors which show the difference between the geometric characteristics of the segments boarding the junctionsâ area of influence and the segment included in that area were added. The choice of the best modeling technique was supported by the result of a cross validation made to ascertain the best model for the three sets of researched contributing factors. The models fitted with random-parameters negative binomial models had the best performance in the process. In the best models obtained for every modeling technique, the characteristics of the road environment, including proxy measures for the geometric consistency, along with traffic volume, contribute significantly to the number of collisions. Both the variables concerning junctions and the various national highway segments in their area of influence, as well as variations from those characteristics concerning roadway segments which border the already mentioned area of influence have proven their relevance and, therefore, there is a rightful need to incorporate the effect of geometric consistency in the three-leg junctions safety studies.

Development of benchmarks for operating costs and resources consumption to be used in healthcare building sustainability assessment methods

Since the last decade of the twentieth century, the healthcare industry is paying attention to the environmental impact of their buildings and therefore new regulations, policy goals and Buildings Sustainability Assessment (HBSA) methods are being developed and implemented. At the present, healthcare is one of the most regulated industries and it is also one of the largest consumers of energy per net floor area. To assess the sustainability of healthcare buildings it is necessary to establish a set of benchmarks related with their life-cycle performance. They are both essential to rate the sustainability of a project and to support designers and other stakeholders in the process of designing and operating a sustainable building, by allowing the comparison to be made between a project and the conventional and best market practices. This research is focused on the methodology to set the benchmarks for resources consumption, waste production, operation costs and potential environmental impacts related to the operational phase of healthcare buildings. It aims at contributing to the reduction of the subjectivity found in the definition of the benchmarks used in Building Sustainability Assessment (BSA) methods, and it is applied in the Portuguese context. These benchmarks will be used in the development of a Portuguese HBSA method.
