Infecção Relacionada com o CVC

Introdução: Os dispositivos invasivos nomeadamente cateteres venosos centrais (CVC) são uma fonte comum de infecção sistémica. Em cuidados intensivos neonatais a taxa de infecção associada ao CVC pode ser muito elevada. A vigilância epidemiológica constitui a base do controlo de infecção associada a estes dispositivos. Objectivo: Analisar a evolução da infecção associada aos CVC numa UCIN. Tipo de estudo: Vigilância epidemiológica. Origem dos dados: Registo Nacional das IACS em UCIN do PNCI/DGS. Período em análise: 2008-2010. Resultados: O número de doentes admitidos foi semelhante nos 3 anos assim como a percentagem de doentes com necessidade de cuidados intensivos e o tempo de internamento nesse nível de cuidados. Pelo contrário verificou-se uma percentagem mais elevada de RNMBP, doentes operados, ventilados e de dias de ventilação. O número de RN com CVC, dias de CVC e taxa de utilização de CVC também foram semelhantes. O número de episódios de infecção por mil dias de internamento foi semelhante mas as sépsis em RN com CVC /1000 dias de CVC ligeiramente superiores (13,9/1000 dias de CVC no último ano) com valores crescentes ao longo dos 3 anos. Pelo contrário a septicémia com origem no CVC tem valores muito baixos (0,4/1000 dias de CVC) o que se deve ao facto de não ser possível tirar sangue para hemocultura nos cateteres epicutaneocava. Os Staphylococcus coagulase negativa foram os agentes mais frequentemente isolados. Na sequência destes resultados foram revistos os cuidados com os CVC e relembradas as medidas básicas de controlo de infecção. Conclusão: A vigilância epidemiológica é uma ferramenta de grande utilidade no controlo de infecção permitindo o conhecimento das taxas basais de infecção e o diagnóstico de desvios da “normalidade”.

Isolation of yellow fever virus (YFV) from naturally infectied Haemagogus (Conopostegus) leucocelaenus (diptera, cukicudae) in São Paulo State, Brazil, 2009

After detecting the death of Howlers monkeys (genus Alouatta) and isolation of yellow fever virus (YFV) in Buri county, São Paulo, Brazil, an entomological research study in the field was started. A YFV strain was isolated from newborn Swiss mice and cultured cells of Aedes albopictus - C6/36, from a pool of six Haemagogus (Conopostegus) leucocelaenus (Hg. leucocelaenus) mosquitoes (Dyar & Shannon) collected at the study site. Virus RNA fragment was amplified by RT-PCR and sequenced. The MCC Tree generated showed that the isolated strain is related to the South American I genotype, in a monophyletic clade containing isolates from recent 2008-2010 epidemics and epizootics in Brazil. Statistical analysis commonly used were calculated to characterize the sample in relation to diversity and dominance and indicated a pattern of dominance of one or a few species. Hg. leucocelaenus was found infected in Rio Grande do Sul State as well. In São Paulo State, this is the first detection of YFV in Hg. leucocelaenus.

A NEW POSSIBILITY FOR SURVEILLANCE: DO WE IDENTIFY ALL CASES OF LEPTOSPIROSIS?

SUMMARY Leptospirosis is a febrile disease with a typically underestimated global incidence, especially in regions where dengue is endemic. Therefore, it is difficult to accurately determine the number of leptospirosis cases in these areas, which contributes to significant under-reporting this disease. In this study, we estimated the number of possible leptospirosis cases among dengue-like cases that were reported during 2008, 2010, and 2012 in the city of Fortaleza, northeast Brazil. Patients were evaluated for dengue and leptospirosis using immunoenzymatic tests for IgM antibodies that were specific to each pathogen. Among the suspected cases of dengue that resulted as negative in laboratory tests, 10.8% (2008), 19.2% (2010), and 30.8% (2012) were confirmed to be leptospirosis. Considering the cases reported by the surveillance authority as dengue that were subsequently discarded based on the laboratory test results, we estimate that the number of actual leptospirosis cases may be 26 to 49 times higher than those diagnosed and reported by the Health Services. Furthermore, we believe that approximately 20% of dengue-like cases may be leptospirosis cases in areas where the two diseases are endemic.

Genotypes of Cryptococcus neoformans and Cryptococcus gattii as agents of endemic cryptococcosis in Teresina, Piauí (northeastern Brazil)

Throughout Brazil, Cryptococcus neoformans is the cause of cryptococcosis, whereas Cryptococcus gattii is endemic to the northern and northeastern states. In this study, the molecular types of 63 cryptococcal isolates recovered from the cerebrospinal fluid of meningitis patients diagnosed between 2008-2010 in Teresina, Piauí, Brazil, were analysed. Out of the 63 patients, 37 (58.7%) were human immunodeficiency virus (HIV)-positive and 26 (41.3%) were HIV-negative. URA5-restriction fragment length polymorphism analysis identified 37/63 (58.7%) isolates as the C. neoformans VNI genotype, predominantly in HIV-positive patients (32/37, 86.5%), and 24/63 (38.1%) as the C. gattii VGII genotype, mostly in HIV-negative patients (21/26, 80.8%). The occurrence of C. gattii VGII in six apparently healthy children and in seven adolescents/young adults in this region reaffirms the endemic occurrence of C. gattii VGII-induced primary cryptococcosis and early cryptococcal infection. Lethality occurred in 18/37 (48.6%) of the HIV-positive subjects and in 13/26 (50%) of the HIV-negative patients. Our results provide new information on the molecular epidemiology of C. neoformans and C. gattii in Brazilian endemic areas.

Conocimientos de la Enfermedad de Chagas por parte de los profesionales sanitarios de tres hospitales en la provincia de Almería

Background: Health professionals who care for patients with imported diseases often lack enough training. The aim of the study is to assess the knowledge of Chagas disease among doctors and nurses attending at-risk pregnant women in our province. Method: descriptive study through a performed anonymous and voluntary knowledge questionnaire for 278 physicians and nurses working at maternity and children's health services in the three hospitals in the province. In Poniente Hospital was established in 2007 a program of screening for the disease in pregnant women. For statistical analysis, quantitative variables were described using the mean and standard deviation. For comparison of qualitative variables we used the chi-square test or Fisher exact test as appropriate. Differences in age and years of experience depending on the hospital were measured by Brown-Forsythe robust test. Results: 116 (41.7%) professionals agreed to participate in the study. 80 (69%) were women and 36 (31%)men,mean age 36.78 years. By professional categories, physicians have a mean of 73.9% correct responses, the nurses 50.7%. Poniente Hospital had the highest percentage of correct answers on aspects of the geographical distribution of the disease (73.7%), the mechanisms of transmission (86%) and diagnosis (82.5%). Conclusions: The Poniente Hospital professionals generally have a better Knowledge about Chagas disease compared with two other professionals hospitals, which probably is related to the existence of the screening program for the disease.

Tuberculosis patients co-infected with Mycobacterium bovis and Mycobacterium tuberculosis in an urban area of Brazil

In this cross-sectional study, mycobacteria specimens from 189 tuberculosis (TB) patients living in an urban area in Brazil were characterised from 2008-2010 using phenotypic and molecular speciation methods (pncA gene and oxyR pseudogene analysis). Of these samples, 174 isolates simultaneously grew on Löwenstein-Jensen (LJ) and Stonebrink (SB)-containing media and presented phenotypic and molecular profiles of Mycobacterium tuberculosis, whereas 12 had molecular profiles of M. tuberculosis based on the DNA analysis of formalin-fixed paraffin wax-embedded tissue samples (paraffin blocks). One patient produced two sputum isolates, the first of which simultaneously grew on LJ and SB media and presented phenotypic and molecular profiles of M. tuberculosis, and the second of which only grew on SB media and presented phenotypic profiles of Mycobacterium bovis. One patient provided a bronchial lavage isolate, which simultaneously grew on LJ and SB media and presented phenotypic and molecular profiles of M. tuberculosis, but had molecular profiles of M. bovis from paraffin block DNA analysis, and one sample had molecular profiles of M. tuberculosis and M. bovis identified from two distinct paraffin blocks. Moreover, we found a low prevalence (1.6%) of M. bovis among these isolates, which suggests that local health service procedures likely underestimate its real frequency and that it deserves more attention from public health officials.

Natalizumab-related anaphylactoid reactions in MS patients are associated with HLA class II alleles.

OBJECTIVES We aimed to investigate potential associations between human leukocyte antigen (HLA) class I and class II alleles and the development of anaphylactic/anaphylactoid reactions in patients with multiple sclerosis (MS) treated with natalizumab. METHODS HLA class I and II genotyping was performed in patients with MS who experienced anaphylactic/anaphylactoid reactions and in patients who did not develop infusion-related allergic reactions following natalizumab administration. RESULTS A total of 119 patients with MS from 3 different cohorts were included in the study: 54 with natalizumab-related anaphylactic/anaphylactoid reactions and 65 without allergic reactions. HLA-DRB1*13 and HLA-DRB1*14 alleles were significantly increased in patients who developed anaphylactic/anaphylactoid reactions (p M-H = 3 × 10(-7); odds ratio [OR]M-H = 8.96, 95% confidence interval [CI] = 3.40-23.64), with a positive predictive value (PPV) of 82%. In contrast, the HLA-DRB1*15 allele was significantly more represented in patients who did not develop anaphylactic/anaphylactoid reactions to natalizumab (p M-H = 6 × 10(-4); ORM-H = 0.2, 95% CI = 0.08-0.50), with a PPV of 81%. CONCLUSIONS HLA-DRB1 genotyping before natalizumab treatment may help neurologists to identify patients with MS at risk for developing serious systemic hypersensitivity reactions associated with natalizumab administration.

Estruturas de governança interna e a capacidade de inovação em pequenas firmas brasileiras de torrefação e moagem de café

Na pesquisa relatada neste artigo são investigadas quais as combinações de estruturas de governança interna (mercado, burocrática e comunitária) que possibilitam mais capacidade de inovação de produto nas pequenas firmas. Neste estudo, inspirado nos trabalhos de Grandori e Furnari (2008; 2010), tem-se como hipótese que a capacidade de inovação ocorre de modo mais consistente nas firmas que adotam uma estrutura de governança interna multimodal. Essa hipótese foi testada por meio de um survey com 80 indústrias brasileiras de torrefação e moagem de café(1). Para encontrar as combinações de estruturas, foi utilizada a análise comparativa qualitativa (QCA) no software fs/QCA versão 2.0 (RAGIN, 2008). Como resultado, verificou-se que a estrutura de governança interna multimodal - que combina práticas de incentivos monetários, burocráticas e comunitárias - apresentou resultados mais consistentes para a inovação das pequenas firmas de torrefação. Esses resultados, ao permitirem identificar os requisitos organizacionais que produzem mais possibilidades de inovação, podem ajudar a traçar ações de políticas públicas e privadas para as empresas brasileiras, de modo a melhorar sua taxa de inovação e a competitividade em seus mercados.

Dímero-D y resultados clínicos a corto plazo en el embolismo pulmonar: papel del tamaño del coágulo en la arteria pulmonar

Introducció: Existeixen factors pronòstics en el embolisme pulmonar (EP) que influeixen en la gravetat del mateix i és necessari estudiar-los. -Objectiu: comparar nivells de dímer-D amb la grandària del coàgul en l'artèria pulmonar en pacients amb EP. -Material i mètodes: Cohorts retrospectiu en pacients amb EP simptomàtic entre 2008-2010 en un hospital comarcal. -Resultats: Els nivells de dímer-D van ser de 4068±2764 ng/ml. En el 46,9% el coàgul es va situar centralment, en el 31,3% va ser segmentari i en el 21,9% va ser subsegmentari. -Conclusió: Alts nivells de dímer-D semblen relacionats amb una localització més proximal del coàgul en l'artèria pulmonar, però no es va poder establir cap relació estadísticament significativa.

A Pneumocystis jirovecii pneumonia outbreak in a single kidney-transplant center: role of cytomegalovirus co-infection.

Pneumocystis jirovecii pneumonia (PCP) and cytomegalovirus (CMV) infection represent possible complications of medical immunosuppression. Between 2005 and 2010, non-human immunodeficiency virus (HIV) PCP patients admitted to a nephrology unit were analyzed for outcome, CMV comorbidity, and patient-to-patient contacts prior to PCP. In contrast to 2002-2004 (no cases) and 2008-2010 (10 cases), a PCP outbreak of 29 kidney-transplant recipients and one patient with anti-glomerular basement membrane disease occurred between 2005 and 2007. None of the patients were on PCP chemoprophylaxis. In four PCP patients, the genotyping data of bronchoalveolar lavage specimen showed an identical Pneumocystis strain. PCP cases had a higher incidence of CMV infection (12 of 30 PCP patients) and CMV disease (four patients) when compared to matched PCP-free controls (p < 0.05). Cotrimoxazole and, if applicable, ganciclovir were started 2.0 ± 4.0 days following admission, and immunosuppressive medication was reduced. In-hospital mortality was 10% and the three-year mortality was 20%. CMV co-infection did not affect mortality. CMV co-infection more frequently occurred during a cluster outbreak of non-HIV PCP in comparison to PCP-free controls. Here, CMV awareness and specific therapy of both CMV infection and PCP led to a comparatively favorable patient outcome. The role of patient isolation should be further investigated in incident non-HIV PCP.
