Information professionals in business context: new professionals, old skills

This communication aims to present some reflections regarding the importance of information in organizational context, especially in business context. The ability to produce and to share expertise and knowledge among its employees is now a key factor in the success of any organization. However, it’s also true that workers are increasingly feeling that too much information can hurt their performance. The existence of skilled professionals able to organize, evaluate, select and disseminate information in organizations appears to be a prerequisite for success. The skills necessary for the formation of a professional devoted to the management of information and knowledge in the context of business organizations will be analysed. Then data collected in two focus group discussion with students from a graduate course in Business Information, from Polytechnic Institute of Porto, Portugal, a will be examined.

Seropositivity for anti-Trypanosoma cruzi antibodies among blood donors of the "Hospital Universitário Regional do Norte do Paraná", Londrina, Brazil

The most frequent form of acquisition of Chagas' disease in endemic areas was the transmission through the feces of contaminated triatominae. However, special attention should be paid in urban areas to transmission by blood transfusion, justifying the compulsory screening of blood donors. Early investigations at blood banks in the town of Londrina, Brazil, demonstrated that the seroprevalence of anti-Trypanosoma cruzi antibodies among blood donors was approximately 7.0% in the fifties9,34. Further studies demonstrated pratically the same seroprevalence until the eighties4,32,41. In an attempt to obtain data about the real dimension of the seropositivity for anti-Trypasonoma cruzi antibodies in the region, the authors carried out a large-scale study on 45,774 serum samples from blood donors of the Hemocentro of Hospital Universitário Regional do Norte do Paraná (HURNP), Universidade Estadual de Londrina. The immunological tests were done at the Division of Clinical Immunology of HURNP from May 1990 to December 1994. The serum samples were studied by the indirect hemagglutination assay (IHA, using kits commercially obtained from EBRAM) and by indirect immunofluorescence (IFI, using kits from LIO SERUM) with anti-human IgG conjugate (LABORCLIN). The results demonstrated that 643 serum samples were positive in both assay corresponding to a seroprevalence of 1.4%, i.e., a significant decrease in anti-Trypanosoma cruzi antibodies in the region in comparison with the previously mentioned rates. Data correlating sex and age of seropositive blood donors are presented, as well as the possible factors that may have contributed to the results observed.

Using Baseline Methods to Identify Non-technical Losses in the Context of Smart Grids

Demand response has gained increasing importance in the context of competitive electricity markets and smart grid environments. In addition to the importance that has been given to the development of business models for integrating demand response, several methods have been developed to evaluate the consumers’ performance after the participation in a demand response event. The present paper uses those performance evaluation methods, namely customer baseline load calculation methods, to determine the expected consumption in each period of the consumer historic data. In the cases in which there is a certain difference between the actual consumption and the estimated consumption, the consumer is identified as a potential cause of non-technical losses. A case study demonstrates the application of the proposed method to real consumption data.

Os reais hospitais militares em Portugal administrados e fundados pelos Irmãos Hospitaleiros de S. João de Deus 1640-1834

RESUMO: Desde 1640 até data extrema de 1834, os Irmãos Hospitaleiros de S. João de Deus foram os responsáveis, directa e indirectamente, pela administração e corpo de enfermagem dos Reais Hospitais Militares em Portugal, actividades que analisamos ao longo dos séculos, desenvolvendo pressupostos temáticos relativamente a sua actuação no tempo e no espaço. É durante o séc. XVII até ao séc. XIX, que vemos os cuidados da corte para com a assistência aos soldados enfermos e doentes, ao publicar inúmera legislação relativamente à complexidade assistencial na área militar, a qual foi por nós compilada para melhor contextualização da importância dos Hospitais Militares em Portugal. Os Regimentos, os Alvarás, os Regulamentos e as Ordens do Dia, constituem um objecto fundamental de pesquisa e análise para caracterizar o quotidiano nesses mesmos locais. Os Hospitais Militares desde a sua fundação, dos primórdios das Guerras da Aclamação em 1640, até ao advento do liberalismo em 1834, eram centros de conhecimento técnico e científico com um corpo assistencial especializado, onde um conjunto pluridisciplinar de profissionais zelava qualitativamente pelos assistidos, e onde os Irmãos Hospitaleiros de S. João de Deus desempenhavam funções de administradores, enfermeiros e capelães. Nesse sentido elaboramos uma listagem cronológica para inter relacionar os Irmãos Hospitaleiros e os Hospitais Militares, pois é impossível separar a Ordem de S. João de Deus da componente assistencial aos enfermos e doentes militares em Portugal. A importância urbana e arquitectónica, que os Reais Hospitais Militares tiveram no contexto orgânico e defensivo nas Praças de Guerra, é realçado pela forma como estes se encontravam implantados e construídos, demarcando-se esteticamente da globalidade edificada, pois constituíam parte integrante dos equipamentos militares, como era teorizado pelos técnicos militares. Assim analisamos a localização dos imóveis, para além do próprio edifício hospitalar, com o meio, ou seja com a urbanidade das Praças de guerra. A sobriedade arquitectónica dos Hospitais Militares, integrada nos grandes ciclos das correntes culturais europeia e nacional, associada à riqueza decorativa e iconoclasta desenvolvida nesses locais, dá-nos uma dimensão da importância científica que esses núcleos assistenciais tiveram, contribuindo para a difusão do culto e circulação da imaginária de S. João de Deus em Portugal e dos Santos venerados nos Hospitais Militares. Desta forma compreendemos o alicerçar devocional que o reino tinha por este Santo, como o fundador do conceito assistencial do hospital moderno. Estando intrinsecamente ligado a este facto vemos o proliferar do culto e da imaginária de S. João de Deus em Portugal, centrando-se a iconografia artística do Santo em torno das localidades onde se enraizaram os Hospitais Militares. Hoje, nos imóveis hospitalares, não é difícil analisar uma lenta evolução da funcionalidade dos seus espaços, gravitando o desenvolvimento estrutural assistencial em torno das enfermarias e salas de cirurgia, mantendo-se perene este arquétipo arquitectónico desde o séc. XVII até meados do séc. XIX, as quais foram levantadas, comparadas e analisadas. Foi com a exclaustração das Ordens Religiosas, pelo Decreto de 29 de Maio de 1834, que acabou a extraordinária e valorosa acção administrativa, tutelar e corpo de enfermagem dos Irmãos Hospitaleiros de S. João de Deus, na área específica da assistência militar em Portugal, extinguindo-se, nalguns casos, os Hospitais Militares, pois o reino não estava preparado para substituir esses profissionais de saúde. O nosso estudo desenvolve-se por cerca de 295 anos, espaço temporal em que os Hospitais Militares foram administrados e fundados pelos Irmãos de S. João de Deus em Portugal.---------ABSTRACT: Since 1640 until 1834 the Hospitaller Brothers of S. John of God were the responsibles, direct and indirectly, for the administration and nursing body of the Royal Military Hospitals in Portugal, activities that we analyse throughout the centuries, developing thematic presuppositions regarding its performance in time and in space. It is during the 17th century until the 19th century, that we see the court’s care with the assistance of the wounded and sick by the publishing of much legislation regarding the assistance complexity in the military area, which was compiled by us in order to achieve a better comprehension of the importance of the Military Hospitals in Portugal. The Regiments, Charters, Regulations and Orders of Day constitute a fundamental object of research and analysis to characterise the quotidian of these locations. The Military Hospitals, since its foundation, in the beginning of the Wars of Acclamation in 1640, until the advent of liberalism in 1834, were centres of technical and scientific knowledge with a specialized assistance body, were a multidisciplinary set of professionals took qualitatively care of the attended, and where the Hospitaller Brothers of S. John of God performed the tasks of administrators, nurses and chaplains. In this perspective, we created a chronological listing in order to relate the Hospitaller Brothers with the Military Hospitals, since it is impossible to separate the Hospitaller Order of S. John of God from the component of assistance to the military sick and wounded in Portugal. The urban and architectural importance that the Royal Military Hospitals had in the organic and defensive context of the War Fortifications is emphasized by the way these were implanted and built and by its architectural demarcation of the edified whole, since they constituted an integrant part of the military equipments, as it was theorized for the military architecture. Therefore we analyse the location of the real estate, analysing not only the hospital building itself, but also its relation with the environment, i. e. with the urbanism of the war fortifications. The architectural sobriety of Military Hospitals, integrated in the big cycles of cultural streams in Europe and Portugal, associated to the decorative and iconoclastic wealth developed in these locations, give us a dimension of the scientific importance that these hospitals had, contributing to the diffusion of the cult and circulation of sculptures and paintings of S. John of God in Portugal and of the Saints revered in the Hospitals. In this way, we understand the consolidation of the devotion that the kingdom had for this Saint, the founder of the assistance concept of the modern hospital. The proliferation of the cult and iconography of S. John of God is intrinsically connected to this fact, the artistic iconography concentrating itself around the localities were the Military Hospitals were built. Today, in the assistance buildings, it is not difficult to analyse a slow evolution of the functionality of its spaces, gravitating the structural assistance development around the infirmaries and surgery rooms, this architectural archetype being perennial from the 17th century until the middle of the 19th century. These infirmaries were pointed out, compared and analysed. It was the expulsion of the Religious Orders, by the Decree of May 29th 1834, that ended with the extraordinary and valorous administrative and tutelary action and nursing body of the Hospitaller Brothers of S. John of God, in the specific area of military assistance in Portugal, extinguishing, in some cases, the Military Hospitals, since the kingdom wasn’t prepared to substitute these health professionals. Our study is developed in a timeframe of 295 years, period in which the Military Hospitals were administrated and founded by the Brothers of S. John of God in Portugal.

PRESENCE OF ANTI-TOXOCARA ANTIBODIES IN CHILDREN SELECTED AT HOSPITAL UNIVERSITÁRIO, CAMPO GRANDE, MS, BRAZIL

Visceral Larva Migrans syndrome (VLM) results from the presence or migration of helminth larvae in humans, who nonetheless only play the role of paratenic hosts in the helminths' life cycle. In humans, VLM can be caused by larvae of various nematode species, chiefly those of the ascarid Toxocara canis, which can then be found at a variety of body sites, such as the liver, lungs, heart, and brain. Clinical and pathological manifestations depend primarily on larvae number and location, infection duration, reinfection occurrence, and host's immunological condition. Signs and symptoms may range from asymptomatic infection to severe disease. In humans, infection is acquired through ingestion of T. canis eggs present in soil, containing larvae in the infective stage7, 8, 9. Indeed, eggs of Toxocara sp. have been found in sandboxes in several public places in the city of Campo Grande, Mato Grosso do Sul state2. This study was carried out to detect the presence of anti-Toxocara antibodies in children attending the Pediatrics division of Hospital Universitário of Universidade Federal de Mato Grosso do Sul at Campo Grande, Brazil. Over the years 1992-94, 454 serum samples, obtained from children of 5.25 ± 3.28 years of mean age and selected at that hospital on the basis of eosinophil count greater than or equal to 1000/mm3 of blood, were tested for the presence of antibodies by means of the ELISA technique employing Toxocara canis larvae excretory-secretory antigens5. A high prevalence rate for toxocariasis (35.55%) was found, which was observed to be associated with eosinophil levels lower than those usually reported in literature. Furthermore, a higher frequency of positive serology among boys was also observed (13 cases in contrast to only 3 among girls), a result also reported by other authors

O erro nos cuidados de enfermagem a indivíduos internados numa unidade de cuidados intensivos - Estudo de caso sobre as representações dos actores de uma unidade pós cirúrgica de um hospital português

Estima-se que em Portugal existam entre 1330 e 2900 mortes anuais devido a erros cometidos por equipas prestadoras de cuidados médicos, mais mortes do que por acidente de viação, 1145 no ano 2006, ou devido ao vírus da imunodeficiência humana (VIH), 873 no mesmo ano. Vários autores afirmam que os enfermeiros são responsáveis por mais efeitos adversos evitáveis do que qualquer outro profissional de saúde, por representarem uma percentagem significativa dos recursos humanos da saúde e por passarem uma grande parte seu do tempo com os utentes. A complexidade das funções desempenhadas, o stress, a imprevisibilidade e a elevada tecnologia que caracterizam uma unidade de cuidados intensivos são reconhecidos como factores indutores de erros humanos e do sistema. Recorrendo a uma abordagem do tipo qualitativo, procurou-se compreender o erro em enfermagem numa Unidade de Cuidados Intensivos (UCI) dando voz aos actores directamente envolvidos. O método seguido foi o estudo de caso, através do qual se pretendeu conhecer em profundidade o fenómeno em estudo, utilizando como técnica o grupo focal, procedendo-se à posterior análise de conteúdo das gravações transcritas. Foi possível constatar que os enfermeiros dão principal relevância aos erros de execução, comunicação e violação de procedimentos, considerando na sua maioria que os erros de execução se devem geralmente a lapsos e falhas, enquanto os erros de planeamento e violação de procedimentos têm origem essencialmente em falhas de informação e conhecimento. Embora pareça existir uma visão sistémica do erro, as consequências surgem frequentemente associadas ao profissional implicado.

Some aspects of dermatophytoses seen at University Hospital in Florianópolis, Santa Catarina, Brazil

Dermatophytoses comprise mycoses which are very frequently diagnosed in the routine of clinical laboratories of Florianópolis, like any other Brazilian cities. However, no clinical or epidemiological studies data have been published for that city so far. To partially clarify these questions, we carried out a study on this subject on patients who sought the mycology services of Hospital of Federal University of Santa Catarina, from January 1995 to November 1996. The most prevalent dermatophyte was Trichophyton rubrum (58.6%), followed by T. mentagrophytes (25.3%), Epidermophyton floccosum (7.2%), Microsporum canis (4.8%), T. tonsurans (1.6%) T. violaceum (1.6%) and M. gypseum (0.8%). The prevalence of T. mentagrophytes was significantly higher for females than for males, with a frequency of 37.3% and 16.0% respectively, which could be explained by higher infection of T. mentagrophytes in feet and nails, which were percentually more affected in females than in males. These results suggest that, in general, the clinical and epidemiological characteristics of dermatophytoses of our study have similar patterns of those occurring in other southern and southeastern Brazilian cities

Agreement between premortem and postmortem diagnoses in patients with acquired immunodeficiency syndrome observed at a brazilian teaching hospital

Acquired immunodeficiency syndrome (AIDS) is one of the main causes of death in adults worldwide. More commonly than in the general population, in patients with AIDS there is substantial disagreement between causes of death which are clinically suspected and those established by postmortem examination. The findings of 52 postmortem examinations were compared to the premortem (clinical) diagnoses, and there was 46% agreement between them. Fifty two percent of the patients had more than one postmortem diagnosis, and 48% had at least one AIDS-related disease not suspected clinically. Cytomegalovirus infection was the commonest (30.7%) autopsy finding, but not a single case had been suspected premortem. Bacterial infection, tuberculosis, and histoplasmosis were also common, sometimes not previously suspected, postmortem findings. This study shows that multiple infections occur simultaneously in AIDS patients, and that many among them are never suspected before the postmortem examination. These findings suggest that an aggressive investigation of infections and cancers should be done in patients with AIDS, particularly in those who do not respond to therapy of an already recognized condition

Relative Frequency of Nosocomial Microorganisms at Unicamp University Hospital from 1987 to 1994

The frequency of microorganisms identified in nosocomial infections at Unicamp University Hospital from 1987 to 1994 was analysed. The most common microorganism was S. aureus (20.9%), which was found in surgical wound, bloodstream and arterial-venous infections. In urinary tract infections (UTI), gram-negative rods (56.5%) and yeasts (9%) predominated. A. baumannii isolates were observed to have increased in the last three years. There was a gradual increase in the frequency of coagulase-negative staphylococci and A. baumannii in bloodstream infections but there wasn’t any change in Candida sp

Sistema pericial para auditoria de registos clínicos

O registo clinico é um documento hospitalar confidencial, nele é registado todo o percurso clinico de um determinado paciente. Esse percurso é registado através da atribuição de códigos descritos num sistema de classificação, também denominados de dados da codificação. Os dados da codificação são armazenados electronicamente numa Base de Dados, e é a partir dela que certas medidas, tais como facturação hospitalar, financiamentos hospitalares anuais, tratamentos médicos, ou até mesmo dados epidemiológicos, são adotadas. Portanto torna-se fundamental a garantia da qualidade na área da codificação clinica, para isso é necessário recorrer a processos de auditorias aos registos clínicos. O processo de auditoria é uma atividade independente de avaliação, cujo objetivo visa acrescentar valor e melhorar os objetos e processos da auditoria. Atualmente uma ferramenta denominada de Programa Auditor é utilizada, contudo essa ferramenta demonstra uma tecnologia já ultrapassada. A Tese que se pretende defender é a de que, através de Sistemas Periciais, é possível realizar auditorias internas aos registos clínicos. Pretende-se ainda demonstrar que dos Sistemas Periciais e um benefício para os peritos na área, pois diminui a probabilidade de erros e torna o processo de verificação menos moroso. Neste contexto, o objetivo desta Dissertação prende-se em definir e implementar um Sistema Pericial que permita a auditoria de registos clínicos hospitalares. O Sistema Pericial dever a ainda ser capaz de traduzir o raciocínio do perito, detectando assim diversos tipos de erros que traduzem num registo clínico não conforme. Por sua vez, foi desenvolvido um protótipo de um Sistema Pericial para auditoria de registos clínicos em linguagem PROLOG. Este mesmo protótipo serviu de base à realização de uma experiência que permitiu comparar com o programa Auditor e verificar a sua aplicabilidade no dia-a-dia hospitalar.

RubBer Contact Dermatitis in patients attended at Walter Cantídio Hospital, Federal University of Ceará, Brasil

Nowadays 70% of the world's rubber supply is synthesized artificially. The process involved in its manufacture is vulcanization which requires many chemical substances for speeding the process, as antioxidants to prevent deterioration of rubber, or others. These substances may constitute important sensitizers and thus be responsible for dermatological diseases like contact dermatitis. The objective of this study is to search for the main sensitizers among these rubber chemicals in a population mostly composed by women of a tropical country and compare the results with the ones obtained from previous studies which tested populations mainly composed by men and on different climates.

PREVALENCE OF ANTI- Toxocara ANTIBODIES IN A RANDOM SAMPLE OF INPATIENTS AT A CHILDREN'S HOSPITAL IN VITÓRIA, ESPÍRITO SANTO, BRAZIL

In the streets of Vitória, in the State of Espírito Santo, Brazil, are large number of stray dogs, many of which are infected with Toxocara canis, suggesting a high risk for human infection. In order to investigate the prevalence of Toxocara infection in children in Espírito Santo we studied the prevalence of anti-Toxocara antibodies in 100 random inpatients over one year of age, at the Children's Hospital N.S. da Glória, the reference children's hospital for the State.All the sera were collected during the period between October 1996 and January 1997. The mean age was 6.6±4.1 yrs. (1 to 14 yrs., median 6yrs.) and there were patients from all of the different wards of the hospital. Sixty-eigth patients came from the metropolitan area of Vitória and the other 32 from 17 other municipalities. The anti-Toxocara antibodies were investigated by ELISA-IgG using a secretory-excretory antigen obtained from second stage larvae. All sera were adsorbed with Ascaris suum antigen before the test. Thirty-nine sera (39%) were positive, predominantly from boys, but the gender difference was not statistically significant (boys:25/56 or 44.6%; girls:14/44 or 31.8%; p=0.311). The prevalence of positive sera was higher, but not statistically significant, in children from the urban periphery of metropolitan Vitória (formed by the cities of Vitória, Cariacica, Vila Velha, Serra and Viana) than in children from 17 other municipalities (44.1% and 28.1% respectively, p=0.190). Although the samples studied do not represent all children living in the State of Espírito Santo, since the Children's Hospital N.S. da Glória admits only patients from the state health system, it is probable that these results indicate a high frequency of Toxocara infection in children living in Espírito Santo. Further studies of population samples are necessary to ascertain the prevalence of Toxocara infection in our country.
