Hemophagocytic lymphohistiocytosis associated with H1N1 virus infection and visceral leishmaniasis in a 4.5-month-old infant

We present a case of a 4.5-month-old boy from Turkey with hemophagocytic lymphohistiocytosis (HLH) associated with H1N1 virus and Leishmania spp. coinfection. Because visceral leishmaniasis can mimic hematologic disorders like HLH, it is important to rule out this clinical condition before starting immunosuppressive therapy. In our case, treatment with liposomal amphotericin B resulted in a dramatic resolution of clinical and laboratory abnormalities.

Rotavirus G2P[4] and G2P[4]+[6] infections during norovirus gastroenteritis outbreak: summer season 2010, Brazil

IntroductionThis study aimed to monitor the seasonality of rotavirus infection, and gain insight into the variability of Brazilian strains.MethodsA total of 28 stool samples were analyzed from 698 revised cases of gastroenteritis during a norovirus outbreak in the summer of 2010 in Guarujá, Brazil. Diagnosis was performed using enzyme-linked immunosorbent assay (ELISA), reverse transcription polymerase chain reaction (RT-PCR), and sequencing.ResultsRotavirus infection was detected in 17.9% (5/28) of samples; 4 samples were G2P[4] genotype, and one G2P[4]+P[6] genotype. G2 and P[4] sequences showed a genetic relationship to strains from India and Russia, respectively.ConclusionsThe seasonal pattern of rotavirus may be a consequence of human activity apart from climate factors.

Clinical and serological evolution in chronic Chagas disease patients in a 4-year pharmacotherapy follow-up: a preliminary study

Introduction The role of trypanocidal therapy in the chronic phase of Chagas disease remains controversial. Methods A total of 13 patients with chronic Chagas disease were treated with benznidazole (5mg/kg/day/60 days) and surveyed via antibody measurement and conventional electrocardiogram over the course of 4 years. Results The antibody titers were significantly reduced after 4 years (p<0.05). Most of the patients showed maintenance of the initial clinical picture (electrocardiographic), with the exception of 4 cases. Conclusions Although trypanocidal therapy in the chronic phase of Chagas disease was of limited effectiveness, we believe that it is beneficial in treating these patients.

Impact of the IL-18 gene polymorphism in response to antiviral therapy in chronic HCV genotype 4 patients

^a Introduction Interleukin (IL)-18 is a well-known major proinflammatory cytokine with broad biological effects. The major immunomodulatory functions of IL-18 include enhancing T cell and natural killer cell cytotoxicity. Serum levels of this cytokine were shown to increase in chronic hepatitis C patients compared to non-infected healthy people. An association between IL-18 gene promoter polymorphisms and pegylated interferon (PEG-IFN) and ribavirin treatment outcomes has been reported for individuals with chronic hepatitis C virus genotype 1 (HCV-1). In this study, HCV genotype 4 (HCV-4) patients were assessed for IL-18 gene polymorphisms and treatment outcomes or severity of liver disease because data concerning the impact of IL-18 gene polymorphisms on patients with HCV-4 infections are limited. Methods This study included 123 chronic HCV-4 Egyptian patients and 123 apparently healthy volunteer blood donors who served as a control group. HCV genotyping was performed using the line probe assay. IL-18 genotyping was performed using the TaqMan Real-Time PCR method in all 246 patient and control samples. Results In our study, all patients had HCV-4. IL-18 gene single nucleotide polymorphism (SNP) (-607C/A) genotype distributions and allele frequencies did not differ between HCV patients and normal healthy subjects or between patient groups when compared according to the therapeutic response. Moreover, the presence of an IL-18 SNP was not associated with histological disease severity. We conclude that the presence of the IL-18 SNP rs1946518 does not affect the outcome of chronic HCV-4 treatment in Egyptian patients. Conclusions The IL-18 SNP rs1946518 does not affect response to treatment in chronic HCV-4 patients.

Implementation of a zebrafish health program in a research facility : A 4-year retrospective study

In the past two decades, zebrafish (Danio rerio)-based research has contributed to significant scientific advances. Still, husbandry and health programs did not evolve at the same pace, as evidenced by the absence of general guidelines. Health monitoring is essential to animal welfare, to permit animal exchanges across facilities, to contribute to robust experimental results, and for data reproducibility. In this study, we report a health program implemented in a zebrafish research facility to prevent, monitor, and control pathogen, and disease dissemination. This program includes quarantine, routine health screening of sentinels, and nonroutine screenings of retired animals and sick/moribund individuals. An extensive list of clinical signs, lesions, and pathogens was monitored based on: daily observation of fish, necropsy, histology, and bacterial culture. The results indicate that the combined analysis of sentinels with the evaluation of sick/moribund animals enables a comprehensive description not only of pathogen prevalence but also of clinical and histopathologic lesions of resident animals. The establishment of a quarantine program revealed to be effective in the reduction of Pseudoloma neurophilia frequency in the main aquaria room. Finally, characterization of the colony health status based on this multiapproach program shows a low prevalence of lesions and pathogens in the facility.

Simulação e otimização da coluna de vácuo II da refinaria de Sines

O trabalho realizado foi desenvolvido no âmbito de um estágio curricular de seis meses realizado na Refinaria de Sines da Galp Energia. O principal objetivo foi a otimização da maior coluna de destilação de vácuo existente, uma vez que com o início do funcionamento de novas unidades, como é o caso do Hydrocraker, a produção de gasóleo de vácuo na Refinaria não é suficiente para assegurar a carga das unidades sendo necessário importar, diminuindo assim as margens das unidades. Foi implementada a simulação da coluna de destilação de vácuo II em ASPEN PLUS® para o caso de design, usando as condições de operação que o licenciador usou nas suas simulações para o re-vamping da unidade. Posteriormente foi efetuada a implementação para o caso de Test Run, em que são verificadas as produções projetadas para a coluna, e foram implementados na coluna 4 casos de operação real, onde foram recolhidos os dados de operação e comparadas as características dos produtos simulados com os resultados obtidos nos ensaios das amostras efetuados pelo Laboratório. No caso de design verifica-se que o modelo representa de forma aceitável as características dos pro-dutos extraídos. Tanto para o caso de Test Run como para os casos reais verifica-se que o modelo representa, na maioria dos casos, as características do destilado e do HVGO nas partes finais das destilações destes produtos, enquanto que o modelo representa as características do LVGO na fase inicial da destilação. Para otimização da coluna de vácuo verificou-se que os parâmetros com maior influência na produção de gasóleo de vácuo são a temperatura da zona de flash da coluna e o caudal de vapor de stripping introduzido no fundo da coluna.

Natural transovarial transmission of dengue virus 4 in Aedes aegypti from Cuiabá, State of Mato Grosso, Brazil

INTRODUCTION: Dengue is the most prevalent arboviral disease in tropical areas. In Mato Grosso, outbreaks are reported every year, but studies on dengue in this state are scarce. METHODS: Natural transovarial infection of Aedes aegypti by a flavivirus was investigated in the Jardim Industriário neighborhood of Cuiabá, Mato Grosso. Eggs were collected with ovitraps during the dry, intermediate, and rainy seasons of 2012. After the eggs hatched and the larvae developed to adulthood, mosquitoes (n = 758) were identified and allocated to pools of 1-10 specimens according to the collection location, sex, and climatic period. After RNA extraction, multiplex semi-nested RT-PCR was performed to detect the four dengue virus (DENV) serotypes, yellow fever virus, West Nile virus and Saint Louis encephalitis virus. RESULTS: DENV-4 was the only flavivirus detected, and it was found in 8/50 pools (16.0%). Three of the positive pools contained females, and five contained males. Their nucleotide sequences presented 96-100% similarity with DENV-4 genotype II strains from Manaus, Amazonas. The minimum infection rate was 10.5 per 1000 specimens, and the maximum likelihood estimator of the infection rate was 11.6 (95% confidence interval: 4.8; 23.3). CONCLUSIONS: This study provides the first evidence of natural transovarial infection by DENV-4 in Ae. Aegypti in Mato Grosso, suggesting that this type of infection might serve as a mechanism of virus maintenance during interepidemic periods in Cuiabá, a city where dengue epidemics are reported every year. These results emphasize the need for efficient vector population control measures to prevent arbovirus outbreaks in the state.

Las humanidades digitales en español y portugués. Un estudio de caso: DíaHD/DiaHD

En el ámbito internacional de las humanidades digitales existe una importante discusión centrada en torno a la forma cómo las estructuras y dinámicas académicas e institucionales de las humanidades digitales favorecen a académicos de países anglófonos en detrimento de académicos de otras partes del mundo. Uno de los retos actuales es identificar a los humanistas digitales que trabajan en otros países e idiomas fuera de un modelo anglófono. En este contexto, el 10 de junio de 2013 tuvo lugar el Día de las humanidades digitales / Dia das humanidades digitais, evento organizado e impulsado por agrupaciones e instituciones que conformaron un grupo de trabajo internacional y que buscaba documentar el discurso, las prácticas y metodologías de las humanidades digitales desarrolladas en castellano y portugués. El artículo busca aportar documentación para problematizar si el discurso y las prácticas de las humanidades digitales en estos idiomas tienen rasgos distintos a las anglófonas.

A formação em rastreio e intervenções breves do álcool muda as atitudes dos profissionais de saúde ocupacional? : estudo quasi experimental exploratório para uma estratégia para o meio laboral

RESUMO - Estudos anteriores nos Cuidados de Saúde Primários (CSP) apontam para um incremento da Deteção Precoce (DP) e Intervenções Breves (IB) em pacientes com Problemas Ligados ao Álcool (PLA) após formação apropriada dos profissionais de saúde (com melhoria das suas atitudes). Este estudo quasi experimental, exploratório, é pioneiro no âmbito da Saúde Ocupacional (SO) para a implementação de Rastreio/DP e IB nos PLA. O objetivo principal foi avaliar se uma formação sobre Rastreio/DP e IB pode melhorar as atitudes dos profissionais de SO ao lidar com os PLA em Meio Laboral (PLAML). Foi aplicado um questionário em duas partes: Q1/pré-formação (variáveis sociodemográficas, profissionais, competências em alcoologia, experiência pessoal com álcool/familiares com PLA, dificuldades em lidar com trabalhadores com PLA, AUDIT-C e SAAPPQ) e Q2/pós-formação (avaliação da formação e das atitudes SAAPPQ - Adequação, Legitimidade, Motivação, Autoestima e Satisfação). Os resultados na amostra (N=39) revelaram um aumento sobretudo na Adequação e Satisfação. No entanto, naqueles com níveis baixos das atitudes pré-formação constou-se melhoria das atitudes à excepção da Autoestima e foram encontradas algumas associações com as características do perfil inicial dos participantes. Sugerem-se estudos posteriores para identificação de pacotes formativos mais efetivos e propostas para um Plano integrador de RIB para PLAML

Implementation progress of mental health services in Rwanda: Bugesera district case

RESUMO: O Ministério da Saúde do Governo do Ruanda identifica a saúde mental como uma área de prioridade estratégica para a intervenção em resposta à alta carga dos transtornos mentais no Ruanda. Ao longo dos últimos 20 anos após o genocídio, o sector público reconstruiu sua Resposta Nacional de Saúde Mental com base no acesso equitativo aos cuidados, através do desenvolvimento de uma Política Nacional de Saúde Mental e novas estruturas de saúde mental. A política de Saúde Mental do Ruanda, revista em 2010, prima pela descentralização e integração dos serviços de saúde mental em todas as estruturas nacionais do sistema de saúde e ao nível da comunidade. O presente estudo de caso tem como objetivo avaliar a situação do sistema de saúde mental de um distrito típico de uma área rural no Ruanda, e sugerir melhorias, incluindo algumas estratégias para monitoras as mudanças. Os resultados do estudo permitirão ao Ruanda reforçar a sua capacidade para implementar o Plano Nacional de Saúde Mental ao nível dos distritos. O relatório também será útil para monitorar o progresso da implementação de serviços de saúde mental nos distritos, incluindo a prestação de serviços de base comunitária e a participação dos usuários, suas famílias e outros interessados na promoção, prevenção, assistência e reabilitação em saúde mental. Este estudo também procurou avaliar o progresso da implementação dos cuidados de saúde mental a nível descentralizado, com vista a compreender as implicações em termos de recursos desses processos. Foi realizada uma análise situacional num local do distrito, baseado em entrevistas com as principais partes interessadas responsáveis, usando o Instrumento de Avaliação de Sistemas de Saúde Mental da Organização Mundial da Saúde (WHO-AIMS). Os resultados sugerem que os recursos humanos para a saúde mental e serviços de base comunitária de saúde mental no distrito continuam a ser extremamente limitados. Os profissionais de saúde mental são adicionalmente limitados na sua capacidade para oferecer intervenções de emergência a pacientes psiquiátricos e garantir a continuidade do tratamento farmacológico a pacientes com condições crônicas. Para planejar efetivamente, de acordo com as necessidades da comunidade, sugerimos que o sistema de saúde mental deve envolver também os representantes das famílias e dos usuários no processo de planificação de modo a melhorar a sua contribuição no processo de implementação das atividades de saúde mental. Este estudo de caso do Distrito de Bugesera oferece a primeira análise de nível distrital dos serviços de saúde mental no Ruanda, e pode servir como uma mais-valia para a melhoria do sistema de saúde mental, incluindo a advocacia para a melhoria da qualidade dos cuidados de saúde mental a este nível, aumentando o financiamento para a implementação de serviços clínicos de saúde mental e os recursos humanos disponíveis para a prestação de cuidados de saúde mental, principalmente a nível dos cuidados primários.--------------------- ABSTRACT: To deal with the high burden of mental health disorders resulting from consequences of the 1994 genocide against Tutsis, the Rwanda Ministry of Health (MoH) considers mental health as a priority intervention. For the last 20 years, Ministry of Health focused on rebuilding a national and equity-oriented mental health program responding to the population needs in mental health. Mental health services are now decentralized and integrated in the national health system, from the community level up to the referral level. This study assessed the situation of mental health services in one rural district in Rwanda. It was aimed at assessing the progress of implementation of mental health care at the decentralized level, focusing on resource implications and processes. This study is based on interviews conducted with key stakeholders, using the World Health Organization's Assessment Instrument for Mental Health Systems (WHO-AIMS). Findings show that human resources for mental health care and community-based mental health services of the assessed district remain extremely limited. Mental health professionals face limitation regarding the ability to provide emergency management of psychiatric patients and to ensure continuity of psychopharmacological treatment of patients with chronic conditions. To improve the implementation process of mental health interventions and activities, a planning process based on community needs and the involvement of representatives of families and users in planning process should be considered. The Bugesera case study on the situation of mental health services can serve as a baseline for improvement of the mental health program in Rwanda, in terms of quality care services, infrastructure and equipment, human and financial resources.

A consagração dos naturais

“One cannot analyse a legal concept outside the economic and socio-cultural context in which it was applied” – such is the longstanding thesis of António Manuel Hespanha. I argue that Hespanha’s line of argument relative to legal concepts is also applicable, mutatis mutandis, to legal agents: the magistrates, advocates, notaries, solicitors and clerks who lived and exercised their professions in a given time and place. The question, then, is how to understand the actions of these individuals in particular contexts – more specifically in late 18th century and 19th century Goa. The main goal of the present thesis was to comprehend how westernized and Catholic Goan elite of Brahman and Chardó origin who provided the majority of Goan legal agents used Portuguese law to their own advantage. It can be divided into five key points. The first one is the importance of the Constitutional liberalism regime (with all the juridical, judicial, administrative and political changes that it has brought, namely the parliamentary representation) and its relations with the perismo – a local political and ideological tendency nurtured by Goan native Catholic elite. It was explored in the chapter 2 of this thesis. The second key point is the repeated attempts made by Goan native Catholic elite to implement the jury system in local courts. It was studied in the chapter 3. Chapter 4 aims to understand the participation of the native Catholic elite in the codification process of the uses and traditions of the indigenous peoples in New Conquests territory. The fourth key point is the involvement of those elites not only in the conflict of civil and ecclesiastical jurisdictions but also in the succession of the Royal House of Sunda. It was analyzed in the chapter 5. The functions of an advocate could be delegated to someone who, though lacking a law degree, possessed sufficient knowledge to perform this role satisfactorily. Those who held a special licence to practice law were known as provisionários (from provisão, or licence, as opposed to the letrados, or lettered). In the Goa of the second half of the 18th century and the 19th century, such provisionários were abundant, the vast majority coming from the native Catholic elite. The characteristics of those provisionários, the role played by the Portuguese letrados in Goa and the difficult relations between both groups were studied in the chapter 6.

Preoperative serum levels of ca 72-4, cea, ca 19-9, and Alpha-fetoprotein in patients with gastric cancer

INTRODUCTION: The clinical importance of preoperative serum levels of CA 72-4, carcinoembryonic antigen (CEA), CA 19-9, and alpha-fetoprotein (AFP) was prospectively evaluated in 44 patients with gastric cancer. METHOD: The serum tumor marker levels were determined by commercial radioimmunoassay kits. Positivity for CA 72-4 (>4 U/mL), CEA (>5 ng/mL), CA 19-9 (>37 U/mL), and AFP (>10 ng/mL) were correlated according to the stage, histology, and lymph node metastasis. RESULTS AND DISCUSSION: CA 72-4 showed a higher positivity rate for gastric cancer (47.7%) than CEA (25%), CA 19-9 (25%), and AFP (0%). The combination of CA 72-4 with CEA and CA 19-9 increased the sensitivity to 61.4%. The positivity rates of CA 72-4 in patients at stages I and II (initial disease) and in patients at stages III and IV (advanced disease) were 9% and 60.6%, respectively (P < 0.005). No correlation was found between CEA and CA 19-9 levels and the stage of gastric cancer. There was a tendency of positivity for CA 72-4 to suggest lymph node involvement, but it was not significant (P = 0.075). Serum levels of tumor markers did not show a correlation with the histological types of gastric cancer. CONCLUSION: Preoperative serum levels of CA 72-4 provided a predictive value in indicating advanced gastric cancer.

Diffuse panbronchiolitis: an underdiagnosed disease? Study of 4 cases in Brazil

BACKGROUND: Diffuse panbronchiolitis is a clinical pathologic condition characterized by chronic inflammation of respiratory bronchioles, with clinical features that position it as a differential diagnosis among the sinopulmonary syndromes. METHODS AND RESULTS: We present 4 cases (1 Black, 2 Japanese descendants, and 1 Japanese), living in Brazil, in which the diagnosis was made by the clinical and radiological features and confirmed by transbronchial biopsy. The clinical findings included chronic sinusitis, productive cough, rhonchi, and wheezes. The pulmonary function tests showed an obstructive pattern. High resolution computerized tomography showed a diffuse nodular pattern, airway ectasia, and airway wall thickening. The biopsy showed interstitial accumulation of foam cells and lymphoid cells in the walls of respiratory bronchioles: 2 of our cases had bronchus-associated lymphoid tissue hyperplasia. We searched for the HLA Bw54 in all of our patients, but only 1 was positive. A low dose macrolide treatment was introduced, resulting in with clinical and functional improvement. A score that rated the extent of nodules, airway ectasia, mucus plugging, and airway wall thickening was applied on pre- and post-treatment High resolution computerized tomography results, revealing an improvement in tomographic pattern related to that observed in the pulmonary function tests. CONCLUSION: We conclude that diffuse panbronchiolitis is a systemic disease that is not exclusive to the Asian population, whose clinical and radiological features should be better known by occidental pulmonary physicians.
