Toxoplasmosis: an examination of knowledge among health professionals and pregnant women in a municipality of the State of Paraná

Introduction The aim of this study was to investigate the knowledge of toxoplasmosis among professionals and pregnant women in the public health services in Paraná, Brazil. Methods A cross-sectional observational and transversal study of 80 health professionals (44 nurses and 36 physicians) and 330 pregnant women [111 immunoglobulin M (IgM)- and IgG-non-reactive and 219 IgG-reactive] was conducted in 2010. An epidemiological data questionnaire was administered to the professionals and to the pregnant women, and a questionnaire about the clinical aspects and laboratory diagnosis of toxoplasmosis was administered to the professionals. Results The participants frequently provided correct responses about prophylactic measures. Regarding the clinical and laboratory aspects, the physicians provided more correct responses and discussed toxoplasmosis with the pregnant women. The professionals had difficulty interpreting the avidity test results, and the physicians stated that they referred pregnant women with high-risk pregnancies to a county reference center. Of the professionals, 53 (91.4%) reported that they instructed women during prenatal care, but only 54 (48.6%) at-risk pregnant women and 99 (45.2%) women who were not at risk reported receiving information about preventive measures. The physicians provided verbal instructions to 120 (78.4%) women, although instructional materials were available in the county. The pregnant women generally lacked knowledge about preventive measures for congenital toxoplasmosis, but the at-risk pregnant women tended to respond correctly. Conclusions This study provides data to direct public health policies regarding the importance of updating the knowledge of primary care professionals. Mechanisms should be developed to increase public knowledge because prophylactic strategies are important for preventing congenital toxoplasmosis.

Illness perception, knowledge and self-care about cervical cancer

Prevention plays a central role in early detection of cervical cancer. Common Sense Model proposes that the nature and organization of illness representations can guide actions related to health and how self-care is exercised. The aim of this study was to describe and compare illness perception, knowledge and self-care in women with and without cancer precursor lesions. Participants were 92 women (aged 18-59) from primary care unity divided into two groups: women with and without premalignant lesion. Measures for illness perception, knowledge and self-care were used. There was no statistically signifi cant difference (t test e chi-square test) between groups in the variables analyzed. Despite the risk for cervical cancer, women with precursor lesions do not adjust their illness perceptions, knowledge and self-care to the situation. These data show the need to warn women against the cervical cancer risks, because their distorted perceptions and lack of knowledge about the disease may hamper the screening and control of cervical cancer.

Dengue in Brazil and Colombia: a study of knowledge, attitudes, and practices

Introduction This study was conducted in Brazil and Colombia,where dengue is endemic and vector control programs use chemical insecticides. Methods We identified knowledge, attitudes, and practices about dengue and determined the infestation levels of Aedes aegypti in one Brazilian and four Colombian communities. Results The surveys show knowledge of the vector, but little knowledge about diagnosis, prognosis, and treatment. Vector infestation indices show Brazil to have good relative control, while Colombia presents a high transmission risk. Conclusions Given the multidimensionality of dengue control, vertical control strategies are inadequate because they deny contextualized methods, alternative solutions, and local empowerment.

Health-related quality of life in patients with Chagas disease: a review of the evidence

Chagas disease (ChD), a neglected tropical disease caused by infection with the parasite Trypanosoma cruzi (T. cruzi), remains a serious public health issue in Latin America and is an emerging disease in several non-endemic countries, where knowledge of the condition and experience with its clinical management are limited. Regionally, the disease is the major cause of disability secondary to tropical diseases in young adults. Health-related quality of life (HRQoL) impairment is common in patients with ChD, especially in those with Chagas dilated cardiomyopathy, the most severe manifestation of the disease, which frequently leads to heart failure. The aim of this review was to conduct a literature search for studies that have evaluated the determining factors of HRQoL in ChD patients. We included cross-sectional, case-control, cohort, and experimental studies, as well as clinical trials that evaluated the HRQoL in ChD patients aged 18 to 60 years and are presenting an explicit description of statistical analysis. Using a combination of keywords based on Descriptors in Health Sciences (DeCS) and Medical Subject Headings (MeSH) for searches in PubMed and the Scientific Electronic Library Online (SciELO), 148 studies were found. After exclusions, 12 studies were selected for analysis. Three main findings were extracted from these studies: 1) cardiac involvement is associated with a worse HRQoL in ChD patients; 2) HRQoL is associated with the patients' functional capacity; and 3) simple and inexpensive therapeutic measures are effective for improving HRQoL in ChD patients. Hence, ChD patients' functional capacity, the effectiveness of non-surgical conservative treatment, and cardiac involvement are important determining factors for the HRQoL in ChD patients.

Development of process control strategies exploiting knowledge from systems biology: application to MDCK suspension cells

Madine Darby Canine Kidney (MDCK) cell lines have been extensively evaluated for their potential as host cells for influenza vaccine production. Recent studies allowed the cultivation of these cells in a fully defined medium and in suspension. However, reaching high cell densities in animal cell cultures still remains a challenge. To address this shortcoming, a combined methodology allied with knowledge from systems biology was reported to study the impact of the cell environment on the flux distribution. An optimization of the medium composition was proposed for both a batch and a continuous system in order to reach higher cell densities. To obtain insight into the metabolic activity of these cells, a detailed metabolic model previously developed by Wahl A. et. al was used. The experimental data of four cultivations of MDCK suspension cells, grown under different conditions and used in this work came from the Max Planck Institute, Magdeburg, Germany. Classical metabolic flux analysis (MFA) was used to estimate the intracellular flux distribution of each cultivation and then combined with partial least squares (PLS) method to establish a link between the estimated metabolic state and the cell environment. The validation of the MFA model was made and its consistency checked. The resulted PLS model explained almost 70% of the variance present in the flux distribution. The medium optimization for the continuous system and for the batch system resulted in higher biomass growth rates than the ones obtained experimentally, 0.034 h-1 and 0.030 h-1, respectively, thus reducing in almost 10 hours the duplication time. Additionally, the optimal medium obtained for the continuous system almost did not consider pyruvate. Overall the proposed methodology seems to be effective and both proposed medium optimizations seem to be promising to reach high cell densities.

Abstract INTRODUCTION: This study investigated the knowledge of users of primary healthcare services living in Ribeirão Preto, Brazil, about dengue and its vector. METHODS: A cross-sectional survey of 605 people was conducted following a major dengue outbreak in 2013. RESULTS: Participants with higher levels of education were more likely to identify correctly the vector of the disease. CONCLUSIONS: The results emphasize the relevance of health education programs, the continuous promotion of educational campaigns in the media, the role of the television as a source of information, and the importance of motivating the population to control the vector.

The World Health Organization Multi-Professional Patient Safety Curriculum : implementation of key modules and its impact on patient safety knowledge, skills, and attitudes of medical students at the University of Algarve

ABSTRACT - Objectives: We attempted to show how the implementation of the key elements of the World Health Organization Patient Safety Curriculum Guide Multi-professional Edition in an undergraduate curriculum affected the knowledge, skills, and attitudes towards patient safety in a graduate entry Portuguese Medical School. Methods: After receiving formal recognition by the WHO as a Complementary Test Site and approval of the organizational ethics committee , the validated pre-course questionnaires measuring the knowledge, skills, and attitudes to patient safety were administered to the 2nd and3rd year students pursuing a four-year course (N = 46). The key modules of the curriculum were implemented over the academic year by employing a variety of learning strategies including expert lecturers, small group problem-based teaching sessions, and Simulation Laboratory sessions. The identical questionnaires were then administered and the impact was measured. The Curriculum Guide was evaluated as a health education tool in this context. Results: A significant number of the respondents, 47 % (n = 22), reported having received some form of prior patient safety training. The effect on Patient Safety Knowledge was assessed by using the percentage of correct pre- and post-course answers to construct 2 × 2 contingency tables and by applying Fishers’ test (two-tailed). No significant differences were detected (p < 0.05). To assess the effect of the intervention on Patient Safety skills and attitudes, the mean and standard deviation were calculated for the pre and post-course responses, and independent samples were subjected to Mann-Whitney’s test. The attitudinal survey indicated a very high baseline incidence of desirable attitudes and skills toward patient safety. Significant changes were detected (p < 0.05) regarding what should happen if an error is made (p = 0.016), the role of healthcare organizations in error reporting (p = 0.006), and the extent of medical error (p = 0.005). Conclusions: The implementation of selected modules of the WHO Patient Safety Curriculum was associated with a number of positive changes regarding patient safety skills and attitudes, with a baseline incidence of highly desirable patient safety attitudes, but no measureable change on the patient safety knowledge, at the University of Algarve Medical School. The significance of these results is discussed along with implications and suggestions for future research.

An agent based architecture to support monitoring in plug and produce manufacturing systems using knowledge extraction

In recent years a set of production paradigms were proposed in order to capacitate manufacturers to meet the new market requirements, such as the shift in demand for highly customized products resulting in a shorter product life cycle, rather than the traditional mass production standardized consumables. These new paradigms advocate solutions capable of facing these requirements, empowering manufacturing systems with a high capacity to adapt along with elevated flexibility and robustness in order to deal with disturbances, like unexpected orders or malfunctions. Evolvable Production Systems propose a solution based on the usage of modularity and self-organization with a fine granularity level, supporting pluggability and in this way allowing companies to add and/or remove components during execution without any extra re-programming effort. However, current monitoring software was not designed to fully support these characteristics, being commonly based on centralized SCADA systems, incapable of re-adapting during execution to the unexpected plugging/unplugging of devices nor changes in the entire system’s topology. Considering these aspects, the work developed for this thesis encompasses a fully distributed agent-based architecture, capable of performing knowledge extraction at different levels of abstraction without sacrificing the capacity to add and/or remove monitoring entities, responsible for data extraction and analysis, during runtime.

Relatório de estágio no departamento central de investigação e acção penal

The means of obtaining evidence, the amount of evidence obtained, the number of defendants related to each criminal case and the gravity of the crimes for which the magistrates of the Department are holders of penal action, define its real importance to the Rule of Law. I have deeply studied the subject of the institution of hierarchical intervention required by the assistant and the application of an opening statement by the defendant, starting from a hypothetical case, provided when the query of an investigation with the subject of the crime of active corruption, where this institution was called as a reaction to the archiving dispatch delivered by the Public Ministry. I have study about the implementation of the institution of provisional suspension of the process, specifically in the scope of fiscal criminality, analyzing the effective satisfaction of the purposes of the sentences in two slopes: general prevention and special prevention. I went for my first time to a Central Court of Criminal Instruction, where I attended the measures of inquiry and instructive debate of a process that culminated with the prosecution and pronunciation of the defendants. In addition to this criminal experience, I have deepened and consolidated the academic knowledge with the study of various criminal cases from various fields in the scope of criminality investigated by the Department. I could therefore check the basis of procedural delays, regarding to our legal system, especially in this type of crime, raising issues that I analyzed and discussed, always in a critical and academic way. I had the opportunity to attend and witness a seminar in the Lisbon Directorate of Finance as well of entering the Centre for Judicial Studies to attend a conference on the International Anti-Corruption Day. Focus on the investigatory importance of the international judicial cooperation, through the various organs, with special interest to EUROJUST. I comprehended the organization and functioning of these communitarian organs and means of communication of procedural acts, in particular, the rogatory letters and european arrest warrants. This involvement is motivated by the moratorium factor of the investigations where rogatory letters are necessary for the acquisition of evidence or information relevant to the good continuation of the process. For this reason the judicial cooperation through the relevant communitarian organs, translates a streamlined response between the competent judicial authorities of the Member States, through the National Member that integrates EUROJUST. This report aims to highlight some of the difficulties and procedural issues that Public Prosecutors of DCIAP and criminal police bodies that assist them, face in combating violent and organized crime, of national and transnational nature, of particular complexity, according to the specifics of criminal types.

A segurança dos consumidores

The present report, about consumer’s safety, shows the development of the knowledge on this particular subject and the actions carried out by entities that fight for the protection of consumer’s rights. The internship was based on the knowledge acquirement on the theoretical and practical aspects of the fight lead by the Direção Geral do Consumidor, together with other entities, towards the elimination or solely the reduction of risks caused by some products and services made available for the consumers or put on the market. During the internship, I counted with the support of my supervisor in the DGC, Dr. Ana Catarina Fonseca and, for the writing of the report, I had the help of my thesis advisor, Dr. Jorge Morais Carvalho, whenever I needed constructive criticism. My participation on the creation of the informative brochures about consumer’s safety, and the study of the legislation used by the DGC on the daily work, enabled me, effectively, to consolidate my guiding principles as a future professional on the matters of the creation of entities, private and public, which aim to ensure the protection of consumers’s rights, informing them of the possible risks or solving the already existing problems, removing dangerous products and services from the market.The report clarifies the action of the DGC on the protection of consumer’s safety, and enables some knowledge on the relations between the entities that work for the protection of the consumers and the market operators and on their work on identifying dangerous products and warning the consumers about it. The final part of this report contains information that allows us to form an idea of the importance that consumer safety has had in Cape Verde, compared with the laws of Portugal on the matter.

Fiscalização dos serviços de informações em Portugal

The present work offers a brief historical and evolutionary introduction to the legal basis of the Portuguese Republic Intelligence System (SIRP) which comprises two services – the Security Intelligence Service (SIS) and the Defence Strategic Intelligence Service (SIED) – and two entities responsible for its oversight – the Supervisory Body (CFSIRP) and the Data Monitoring Committee (CFD), also responsible for supervising the Military Intelligence and Security Centre (CISMIL) of the General Staff of the Armed Forces (EMGFA). The initial narrative subsequently leads us to a detailed analysis of the Portuguese Intelligence services' current model of monitoring, as well as of the legislator’s options, namely in the legal drafting field, used within the construction and definition of the legal structure that currently regulates the Portuguese Republic Intelligence System. For the purposes of this study we have broadly examined different models of the European Union, in particular those of Belgium, the Netherlands and Croatia. We have also transposed to the text the valuable contributions collected during the research phase, more precisely the replies to questionnaires and interviews conducted with certain individuals selected according to their knowledge and affinity with the subject of this study, including members and former members of the Supervisory Body and former directors of the three portuguese intelligence services. The present dissertation intends to contribute to the development of this subject, promoting critical analysis, within and beyond the academia, with the aim that some of its reflections might be useful towards the intelligence system’s future reform, particularly in what concerns intelligence services monitoring.

Towards a knowledge society

Economies are moving towards competitive stadiums based on knowledge and innovation. The changing environment and the level of globalization demand important efforts in order to sustain competitive advantages. Portugal has experienced a remarkable evolution since its adhesion to the European Union in several fields: economic development, Research & Development (R&D) consolidation, health parameters and social cohesion. As other developed economies, Portugal started its journey towards a knowledge-based economy and has been consolidating an innovation system during the last 35 years. The following report aims to analyze the evolution of a system since its creation to its last transformation within a globalized context. Challenges such as the lack of maturity of the system, the economic crisis, the European paradox, and closing the gap with other European countries are addressed in the next chapters. Likewise, recommendations on these points are provided by the end of the report as potential solutions.
