Identificação de Enterobacter spp. através de técnicas convencionais e do sistema semi-automatizado Microscan (Autoscan-4)

A hundred and ninety-five (195) strains of Enterobacter spp., isolated from diverse clinical specimens - urine, feces, cateter, blood, wound, tracheal aspirate, vaginal fluid - were submitted to the conventional identification by biochemical tests, and were also submitted to the identification by panels NegCombo 20 of the system automated MicroScan - AutoScan- 4 (Dade Behring Inc., West Sacramento, CA, USA). The samples were from patients of the Clinical Laboratory from the School of Pharmacy and Biochemistry of UNOESTE, Presidente Prudente, SP, and from patients hospitalized at the University Hospital Domingos Leonardo Cerávolo, UNOESTE. Of the total of strains tested, 191 (97.9%) presented agreement between the two approaches utilized and 4 strains (2.1%) presented identification disagreement, that is, the genus identified was different in each approach. By this study, the conclusion is that both the approaches utilized for the identification presented advantages and disadvantages related to the cost, facility of execution, quickness, reliability and some other characteristics. Even so, our results showed that conventional methods represent a reliable tool for Enterobacter identification.

Cysteine proteinase inhibitors regulate human and mouse osteoclastogenesis by interfering with RANK signaling

The cysteine proteinase inhibitor cystatin C inhibited RANKL-stimulated osteoclast formation in mouse bone marrow macrophage cultures, an effect associated with decreased mRNA expression of Acp5, Calcr, Ctsk, Mmp9, Itgb3, and Atp6i, without effect on proliferation or apoptosis. The effects were concentration dependent with half-maximal inhibition at 0.3 μM. Cystatin C also inhibited osteoclast formation when RANKL-stimulated osteoclasts were cultured on bone, leading to decreased formation of resorption pits. RANKL-stimulated cells retained characteristics of phagocytotic macrophages when cotreated with cystatin C. Three other cysteine proteinase inhibitors, cystatin D, Z-RLVG-CHN2 (IC50 0.1 μM), and E-64 (IC 50 3 μM), also inhibited osteoclast formation in RANKL-stimulated macrophages. In addition, cystatin C, Z-RLVG-CHN2, and E-64 inhibited osteoclastic differentiation of RANKL-stimulated CD14+ human monocytes. The effect by cystatin C on differentiation of bone marrow macrophages was exerted at an early stage after RANKL stimulation and was associated with early (4 h) inhibition of c-Fos expression and decreased protein and nuclear translocation of c-Fos. Subsequently, p52, p65, IκBα, and Nfatc1 mRNA were decreased. Cystatin C was internalized in osteoclast progenitors, a process requiring RANKL stimulation. These data show that cystatin C inhibits osteoclast differentiation and formation by interfering intracellularly with signaling pathways downstream RANK. © FASEB.

Ouvidoria do SUS: um instrumento de gestão participativa?

Nesta dissertação discute-se a ouvidoria pública brasileira quanto mecanismo de defesa dos direitos dos cidadãos, especificamente a Ouvidoria do Sistema Único de Saúde (SUS) no estado do Pará e se esta constitui-se enquanto um instrumento de gestão participativa, conforme preconiza o Ministério da Saúde. No estudo observaram-se os processos de implantação, implementação e descentralização no âmbito da gestão estadual da política pública no estado do Pará. Adotou-se abordagem qualitativa que possibilitou à investigação dos processos de relações sociais, cujos dados puderam ser obtidos através de documentos e entrevistas com os sujeitos envolvidos no tema em questão. Evidencia-se que a ouvidoria pública, como qualquer aparelho estatal é um espaço de luta política, desta forma teceu-se considerações sobre o Estado a partir de Marx, Gramsci e Poulantzas, destacando a reforma sofrida pelo Estado brasileiro dos anos 1990, a qual Behring caracterizou de contrarreforma por conta de sua tendência a amortizar direitos sociais e trabalhistas já conquistados. Em seguida apresentam-se pontos de vista diferente em relação à chamada democracia participativa que pode se identificar tanto com o pensamento liberal reformado ou colocar-se na perspectiva transformadora da sociedade por meio da radicalização da democracia. Embasado na matriz teórica marxista analisa-se a literatura existente sobre a ouvidoria pública e apresenta-se a Política Nacional de Gestão Estratégica e Participativa do SUS, cuja ouvidoria é um dos seus elementos. Os resultados mostraram que a forma como a Ouvidoria do SUS foi concebida e a concepção de participação adotada por esta a qual limitase a um mero instrumento de aferição da satisfação dos usuários são sem dúvida os principais obstáculos para que a Ouvidoria seja, de fato, um instrumento de gestão participativa.

Perfil soroepidemiológico da Rubéola no período pré-vacinal (1989 a 1999) e pós-vacinal (2000 a 2005) de pacientes referenciados ao Instituto Evandro Chagas

A Rubéola é uma virose exantemática geralmente de evolução benigna, mas quando adquirida durante a gestação, pela teratogenicidade do vírus, pode provocar a Síndrome da Rubéola Congênita caracterizada por malformações fetais e aborto espontâneo. Com o objetivo de descrever o perfil soroepidemiológico da Rubéola de pacientes referenciados ao Instituto Evandro Chagas/SVS/MS nos períodos prévacinal(1989 a 1999) e pós-vacinal (2000 a 2005), foi realizado estudo retrospectivo do banco de dados de 34.221 amostras, cujos testes sorológicos foram analisados através da técnica de pesquisa de IgM e IgG por ELISA com kits do laboratório DADE BEHRING^®. A taxa de infecção encontrada foi de 17,2% no período prévacinal e de 4,0% no pós-vacinal. Entre a sintomatologia apresentada no período pré-vacinal, a linfadenopatia teve maior taxa com 38,4% e no pós-vacinal a artralgia com 11,3%. Nas mulheres em idade fértil, a média da taxa de imunes foi de 78,3% e 84,4% no período pré e pós-vacinal, respectivamente. A taxa de infecção em gestantes no período pré-vacinal foi de 9,3% e no pós-vacinal 1,6%. Os recémnascidos infectados corresponderam a 2,1% no período pré e 1,0% no período pósvacinal nesses, houve predomínio de catarata e cardiopatia isoladas ou em associação. Foi concluído que houve diferença significante entre as frequências de todos os segmentos estudados, em relação aos períodos pré e pós-vacinal, confirmando a eficácia da vacina na prevenção da Rubéola e da SRC, tal fato realça a necessidade de se ampliar as coberturas vacinais para impedir a circulação do VR no país, cumprindo assim o acordo de eliminação até o ano 2010.

Weight Training, Aerobic Physical Activities, and Long-Term Waist Circumference Change in Men

ObjectiveFindings on weight training and waist circumference (WC) change are controversial. This study examined prospectively whether weight training, moderate to vigorous aerobic activity (MVAA), and replacement of one activity for another were associated with favorable changes in WC and body weight (BW).MethodsPhysical activity, WC, and BW were reported in 1996 and 2008 in a cohort of 10,500 healthy U.S. men in the Health Professionals Follow-up Study. Multiple linear regression models (partition/substitution) to assess these associations were used.ResultsAfter adjusting for potential confounders, a significant inverse dose-response relationship between weight training and WC change (P-trend<0.001) was observed. Less age-associated WC increase was seen with a 20-min/day activity increase; this benefit was significantly stronger for weight training (-0.67 cm, 95% CI -0.93, -0.41) than for MVAA (-0.33 cm, 95% CI -0.40, -0.27), other activities (-0.16 cm, 95% CI -0.28, -0.03), or TV watching (0.08 cm, 95% CI 0.05, 0.12). Substituting 20 min/day of weight training for any other discretionary activity had the strongest inverse association with WC change. MVAA had the strongest inverse association with BW change (-0.23 kg, 95% CI -0.29, -0.17).ConclusionsAmong various activities, weight training had the strongest association with less WC increase. Studies on frequency/volume of weight training and WC change are warranted.

Underlying Event measurements in pp collisions at root s=0.9 and 7 TeV with the ALICE experiment at the LHC

We present measurements of Underlying Event observables in pp collisions at root s = 0 : 9 and 7 TeV. The analysis is performed as a function of the highest charged-particle transverse momentum p(T),L-T in the event. Different regions are defined with respect to the azimuthal direction of the leading (highest transverse momentum) track: Toward, Transverse and Away. The Toward and Away regions collect the fragmentation products of the hardest partonic interaction. The Transverse region is expected to be most sensitive to the Underlying Event activity. The study is performed with charged particles above three different p(T) thresholds: 0.15, 0.5 and 1.0 GeV/c. In the Transverse region we observe an increase in the multiplicity of a factor 2-3 between the lower and higher collision energies, depending on the track p(T) threshold considered. Data are compared to PYTHIA 6.4, PYTHIA 8.1 and PHOJET. On average, all models considered underestimate the multiplicity and summed p(T) in the Transverse region by about 10-30%.

The Seville Expert Workshop for Progress in Posttransplant Lymphoproliferative Disorders

Posttransplant lymphoproliferative disorders (PTLDs) are associated with significant morbidity and mortality among solid-organ transplant patients, but approaches to diagnosis and management vary considerably. An international multidisciplinary panel evaluated current understanding of risk factors and classification systems and developed recommendations to aid in PTLD prevention. We considered evidence on PTLD risk factors including Epstein- Barr virus serostatus and immunosuppression and identified knowledge gaps for future research. Recommendations address prophylactic and preemptive strategies to minimize PTLD development, including modulation of immunosuppression and antiviral drug regimens. Finally, new classification criteria were outlined that may help facilitate standardized reporting and improve our understanding of PTLD.

EPOS 2012: European position paper on rhinosinusitis and nasal polyps 2012. A summary for otorhinolaryngologists

The European Position Paper on Rhinosinusitis and Nasal Polyps 2012 is the update of similar evidence based position papers published in 2005 and 2007. The document contains chapters on definitions and classification, we now also propose definitions for 'difficult to treat' rhinosinusitis, control of disease and better definitions for rhinosinusitis in children. More emphasis is placed on the diagnosis and treatment of acute rhinosinusitis. Throughout the document the terms chronic rhinosinusitis without nasal polyps (CRSsNP) and chronic rhinosinusitis with nasal polyps (CRSwNP) are used to further point out differences in pathophysiology and treatment of these two entities. There are extensive chapters on epidemiology and predisposing factors, inflammatory mechanisms, (differential) diagnosis of facial pain, genetics, cystic fibrosis, aspirin exacerbated respiratory disease, immunodeficiencies, allergic fungal rhinosinusitis and the relationship between the upper and lower airways. The chapters on paediatric acute and chronic rhinosinusitis are totally rewritten. Last but not least all available evidence for management of acute rhinosinusitis and chronic rhinosinusitis with or without nasal polyps in adults and children is analyzed and presented and management schemes based on the evidence are proposed. This executive summary for otorhinolaryngologists focuses on the most important changes and issues for otorhinolaryngologists.
