Lastly, this report analyzes some decisions delivered by the President in the respective institutional procedures which took place in the Centre.

Demographic determinants of survival of people living with HIV attending an outpatient reference unit in the city of Três Lagoas, state of Mato Grosso do Sul, Brazil, in the period 1984-2009

INTRODUCTION: While the incidence of HIV infection and AIDS is increasing in small Brazilian cities, epidemiological studies are often conducted in large urban centers. METHODS: Our group conducted a retrospective analysis of survival determinants among 358 patients who attended a reference unit in a small city. RESULTS: Death risk was lower among men that had sex with men, patients with an HIV-seropositive partner, and those admitted after highly active antiretroviral therapy (HAART) was available. CONCLUSIONS: The study documents the striking beneficial effect of HAART. The finding of other groups with improved survival may aid in the development of programmatic strategies.

The first report of infection with Klebsiella pneumoniae carrying the bla kpc gene in State of Mato Grosso do Sul, Brazil

The increased frequency and dissemination of enterobacteria resistant to various antimicrobials is currently worldwide concern. In January 2010, a 94-year-old patient with chronic lymphocytic leukemia was admitted to the University Hospital. This patient died 21 days after hospitalization due to the clinical worsening. Klebsiella pneumoniae producing of extended-spectrum β-lactamases (ESBLs) was isolated of urine culture. This bacterium demonstrated resistance to ceftazidime, ciprofloxacin, levofloxacin, ertapenem and imipenem. Susceptibility to cefoxitin, cefepime, meropenem, colistin and tigecycline. This study reports the first case of infection by Klebsiella pneumoniae carrying the bla kpc gene in the State of Mato Grosso do Sul, Brazil.

Monitoring Trypanosoma cruzi infection in triatomines using PCR in Mato Grosso do Sul, Brazil

Introduction The aim of the present study was to assess the polymerase chain reaction (PCR) as a method for detecting Trypanosoma cruzi infection in triatomines that had been previously determined by microscopic examination in the State of Mato Grosso do Sul, Brazil. Methods In total, 515 specimens were collected. Material from the digestive tract of each triatomine was analyzed for the presence of T. cruzi by microscopic examination and PCR using the 121/122 primer set. Results Among the 515 specimens tested, 58 (11.3%) were positive by microscopy and 101 (19.61%) were positive by PCR and there was an association between the results of the techniques (χ2 = 53.354, p = 0.001). The main species of triatomine identified was T. sordida (95.5%) Conclusions The use of PCR in entomological surveillance may contribute to a better assessment of the occurrence of T. cruzi in triatomine populations.

Antifungal susceptibility and distribution of Candida spp. isolates from the University Hospital in the municipality of Dourados, State of Mato Grosso do Sul, Brazil

Introduction Hospital infections caused by Candida spp. are a leading cause of morbidity and mortality in hospitalized patients, particularly those that are critically ill or immunocompromised. In this study, the distribution of Candida species in isolates from the University Hospital of the Federal University at Grande Dourados and their in vitro susceptibility to antifungal drugs were analyzed. Methods Yeasts were phenotypically identified using classical methodologies. Antifungal susceptibility tests to amphotericin B and fluconazole were performed using the broth microdilution technique. Results A total of 50 Candida isolates were obtained from hospitalized patients during the study period. We analyzed yeast isolates from urine (n=31; 62%), blood (n=12; 24%), and tracheal secretions (n=7; 14%). The following Candida species were identified: C. tropicalis (n=21; 42%), C. albicans (n=18; 36%), C. glabrata (n=10; 20%), and C. krusei (n=1; 2%). Antifungal susceptibility tests demonstrated that C. albicans was susceptible to both antifungal agents. However, 31.2% of the non-C. albicans Candida isolates displayed dose-dependent susceptibility to fluconazole, and 3.1% were resistant to amphotericin B. Conclusions In contrast to previous reports, our results indicated that C. tropicalis was the most commonly isolated yeast species among the hospital patients. The predominance of non-C. albicans Candida infections confirms the importance of species-level identification for implementing appropriate antifungal therapies.

Evaluation of natural foci of Panstrongylus megistus in a forest fragment in Porto Alegre, State of Rio Grande do Sul, Brazil

Introduction Panstrongylus megistus is commonly found in wild environments of the State of Rio Grande do Sul, Brazil. The aim of this study was to characterize the network of refuges used by triatomine in a forest fragment of Porto Alegre and to identify Trypanosoma cruzi infection, associated hosts and the epidemiological importance of both hosts and triatomines. Methods Techniques including the spool-and-line method and active searching (transects) were used to identify natural foci. Results The food source for each triatomine was determined using the precipitin test, and the infection of marsupials was determined by xenodiagnosis. A total of 33 adults (domestic environment) and 27 nymphs (wild environment) of P. megistus were found in addition to 43 Didelphis albiventris specimens. The infection rates of triatomine adults, triatomine nymphs and opossums with T. cruzi I were 64%, 73% and 69%, respectively. Birds, rodents and opossums were the main resources used by triatomine. Conclusions This work presents the first characterization of a natural focus of P. megistus in Rio Grande do Sul. The natural characteristics of this focus and its implication in the transmission of T. cruzi are discussed.

Detection of arboviruses of public health interest in free-living New World primates (Sapajus spp.; Alouatta caraya) captured in Mato Grosso do Sul, Brazil

Introduction A sero-epidemiological survey was undertaken to detect the circulation of arboviruses in free-living non-human primates. Methods Blood samples were obtained from 16 non-human primates (13 Sapajus spp. and three Alouatta caraya) that were captured using terrestrial traps and anesthetic darts in woodland regions in the municipalities of Campo Grande, Aquidauana, Jardim, Miranda and Corumbá in the State of Mato Grosso do Sul, Brazil. The samples were sent to the Instituto Evandro Chagas (IEC) in Ananindeua, Pará, Brazil, to detect antibodies against 19 species of arboviruses using a hemagglutination inhibition test (HI). Results Of the 16 primates investigated in the present study, five (31.2%) were serologically positive for an arbovirus. Of these five, two (12.5%) exhibited antibodies to the Flavivirus genus, one (6.2%) exhibited a monotypic reaction to Cacipacoré virus, one (6.2%) was associated with Mayaro virus, and one (6.2%) was positive for Oropouche virus. Conclusions Based on the positive serology observed in the present study, it was possible to conclude that arboviruses circulate among free-living primates. The viruses in the areas studied might have been introduced by infected humans or by primates from endemic or enzootic areas. Studies of this nature, as well as efficient and continuous surveillance programs, are needed to monitor viral activities in endemic and enzootic regions.

Análise de novos materiais de adição para reparação naval

A crescente competitividade empresarial existente nos dias de hoje leva as empresas a adquirir uma postura diferente face ao mercado. A concorrência dos países que têm como maior trunfo a abundância de mão-de-obra barata como a China, Índia e Coreia do Sul, obriga os países ditos mais desenvolvidos a traçar uma nova estratégia. Essa estratégia passa pela diferenciação do produto em termos qualitativos, pela procura de novos materiais e técnicas de fabrico inovadoras, pela implementação de alta tecnologia aliada à constante preocupação ambiental. A Lisnave é uma empresa prestadora de serviços na área da reparação e manutenção naval, área que se tem vindo a mostrar bastante lucrativa no sector naval. Nos inúmeros serviços prestados pela empresa, o recurso a juntas soldadas é constante, levando à necessidade de se realizar um estudo de novos materiais de adição utilizados no processo de soldadura por fios fluxados autoprotegidos. Trata-se de um processo que pode funcionar em estaleiro e que permite maiores rendimentos, uma redução significativa no desperdício de material por se tratar de um consumível continuo, levando a uma redução de tempo de soldadura e consequentemente a uma redução do custo global de soldadura. Este trabalho visou estudar a soldadura em reparação naval de 2 fios consumíveis: Um fio autoprotegido (FABSHIELD XLR-8) e um fluxado (FLUXOFIL 19HD) com protecção gasosa por

Prevalence of latent tuberculosis and treatment adherence among patients with chronic kidney disease in Campo Grande, State of Mato Grosso do Sul

Introduction The primary strategy for tuberculosis control involves identifying individuals with latent tuberculosis. This study aimed to estimate the prevalence of latent tuberculosis in chronic kidney disease (CKD) patients who were undergoing hemodialysis in Campo Grande, State of Mato Grosso do Sul, Brazil, to characterize the sociodemographic and clinical profiles of patients with latent tuberculosis, to verify the association between sociodemographic and clinical characteristics and the occurrence of latent tuberculosis, and to monitor patient adherence to latent tuberculosis treatment. Methods This epidemiological study involved 418 CKD patients who were undergoing hemodialysis and who underwent a tuberculin skin test. Results The prevalence of latent tuberculosis was 10.3%. The mean patient age was 53.43±14.97 years, and the patients were predominantly men (63.9%). The population was primarily Caucasian (58.6%); half (50%) were married, and 49.8% had incomplete primary educations. Previous contact with tuberculosis patients was reported by 80% of the participants. Treatment adherence was 97.7%. Conclusions We conclude that the prevalence of latent tuberculosis in our study population was low. Previous contact with patients with active tuberculosis increased the occurrence of latent infection. Although treatment adherence was high in this study, it is crucial to monitor tuberculosis treatment administered to patients in health services to maintain this high rate.

Geographical distribution of Trypanosoma cruzi in triatomine vectors in the State of Mato Grosso do Sul, Brazil

Introduction This work presents the initial findings of a molecular epidemiological investigation of Trypanosoma cruzi in triatomine insects in State of Mato Grosso do Sul. Methods A total of 511 triatomines from different regions of the state were examined. Deoxyribonucleic acid (DNA) was extracted from the intestinal contents of the insects using phenol-chloroform-isoamyl alcohol (25:24:1). Polymerase chain reaction (PCR) using primers 121/122 targeting DNA kinetoplast (kDNA) was then performed to identify T. cruzi, and positive samples were subjected to PCR using the primer pair TcSC5D-F/R followed by restriction fragment length polymorphism (RFLP) with the restriction enzymes SphI and HpaI (1 U/reaction), cloning and sequencing. Results One hundred samples were positive for T. cruzi, and three discrete typing units (DTUs) were identified (TcI, TcII, and TcBat). Triatoma sordida had the highest T. cruzi occurrence (83.3%), and DTUs were found in three samples: 58.3% of the samples were TcI, 33.3% were TcII and 8.3% were TcBat. There was a clear geographical distribution of the DTUs throughout the state, with TcI, TcII and TcBat located in the center, TcI located in the east, and TcII located in the west. Conclusions This study showed the occurrence of overlapping DTUs in State of Mato Grosso do Sul. The distributions of the DTUs were different, with TcI, TcII and TcBat in the center of the state, TcI predominantly in the east, and TcII in the west. Further studies may reveal a more defined mosaic distribution of DTUs in MS.

Neste projeto pretende-se explicar qual a importância que uma política de resseguro, adotada por uma empresa de seguros, no contexto do Solvência II. O desenvolvimento dessa política pretenderá ajudar a Seguradora a escolher os parâmetros contratuais de resseguro mais favoráveis à empresa, assim como definir quantos e por quais Resseguradores deverá optar nos tratados de resseguro, procurando criar uma nova política de resseguro que tenha um impato diminuto nos riscos de subscrição e de contraparte, ao mesmo tempo que garanta um retorno adequado para Companhia. A escolha das melhores soluções de resseguro serão efetuadas tendo em conta o menor custo na sua contratação e a otimização nos requisitos de capital face à necessidade de subscrição de novos negócios. Será neste ponto que se irá abordar o efeito que o risco de subscrição terá nos requisitos de capital através da criação de cenários, que terão por base a alteração de vários parâmetros. Esta análise mais específica será efetuada pela primeira vez nesta Seguradora. Os cenários criados terão em vista vários aspetos para a Seguradora, desde a otimização do custo de resseguro ao crescimento da sua carteira face ao seu apetite ao risco, através da alteração nos seus tratados de resseguro, mais especificamente nos seus parâmetros. Estas novas alterações pretendem ter impato mais favorável na sua margem de solvência face às anteriores políticas de resseguro implementadas. Em suma, pretende-se desenvolver uma nova política de resseguro que ajude a Seguradora a otimizar os seus riscos de subscrição e de contraparte, tendo em conta as análises e conclusões identificadas por cada cenário e determinar qual será o efeito nos requisitos de capital no âmbito do Solvência II.

Repartição do Habitat entre Psitacídeos Simpátricos no Sul da Amazônia

Estudaram-se de agosto de 1977 a junho de 1979 16 espécies de Psitacídeos na região do Núcleo Pioneiro Humboldt (10019' S, 590 12' W), alto rio Aripuanã, MT, Brasil. Verificou-se que diferentes tamanhos de corpo e peso dão acesso a espectros alimentares diferentes. Com respeito ao peso, as 16 espécies podem ser divididas em quatro grupos:55 até 110g: Tuit huetii, Pyrrhura picta, Brotogeris chrysopterus, Pyrrhura rhodogaster, Aratinga weddellii.140 até 300g: Aratinga leucophthalmus, Pionopsitta barrabandi, Pionus menstruus, Deroptyus accipitrinus.360 até 600g: Ara severa, Ara manilata, Amazona ochrocephala, Amazona farinosa.950 até 1350g: Ara ararauna, Ara macao, Ara chloroptera.As estratégias alimentares variam dentro de cada grupo de peso: Ara manilata é especialista puro, Tuit huetti, Brotogeris chrysopterus, Pionopsitta barrabandi, Ara severa e Ara ararauna são especialistas parciais. Os especialistas parciais têm bicos relativamente compridos e estreitos. Com respeito às proporções do bico, Brotogerischrysopterus é mais especializado do que Tuit huetii no mesmo grupo de peso.As espécies muito próximas morfologicamente, como Ara chloroptera e Ara macao ou Pyrruhura rhodogaster e Pyrrhura picta, podem ser reconhecidas principalmente pelo modo com que exploram o habitat. Ara chloroptera se encontra nas estratos superiores da floresta, junto às copas de árvores muito altas, com maior freqüência do que Ara macao. Pyrrhura rhodogaster visita mais freqüentemente matas densas e vegetação secundária do que Pyrrhura picta. Diferenças sazonais de abundância e épocas diferentes de reprodução separam as duas espécies de Amazona. Amazona ochrocephala é mais comum e inclusive cria os seus filhotes na época seca, enquanto que Amazona farinosa reproduz e se torna mais comum na época chuvosa.
