Comparação entre o sistema Autoścan-4 e métodos convencionais na identificação de bacilos Gram-negativos não fermentadores, isolados de materiais clínicos de pacientes em Presidente Prudente - SP

Ninety eight strains of glucose-nonfermenting Gram-negative bacilli were analyzed and isolated from several clinical materials of 95 patients admitted at the Dr. Domingos Leonardo Cerávolo University Hospital and three from outpatients. All of them were assisted in the Laboratory of Clinical Analysis of Unoeste University, Presidente Prudente, SP, from the period of October of 1999 to April of 2001. In this work, the level of agreement between the semi-automated commercial system AutoScan-4 and the conventional system for the identification of those bacteria were studied comparatively. There was agreement in 81 (82.7%), showing that both methodologies are useful for identification; partial agreement in six strains (6.1%) and disagreement in 11 (11.2%). The comercial system did not identify nine (9.2%) of the strains and reported them as very rare biotypes.

Epidemiologia de candidíase hospitalar: Importância da identificação específica

Nosocomial infections with Candida species are recognized as a significant cause of morbidity and mortality in both seriously ill immunocompetent and immunocompromised patients. Infections with Candida albicans and non-albicans Candida species have become a significant cause of infection in humans. Several of the more commonly Candida spp isolates are less susceptible to the antifungal drugs currentlly applied in clinical treatment, a factor that means significant difficulties for effective treatment. The modern mycology laboratory has an important role to play in several aspects relating to these organisms, including therapy, detection, identification and epidemiological analysis. In this study, we have provided an initial comparison of differences in species distribution among Candida isolates from four general hospitals of São Paulo,SP. Overall, 40 isolates of C. albicans, C. parapsilosis and C. tropicalis were isolated respectively in 35%, 50% and 15%, revealed a tendency of higher frequency of non-albicans species. The species distribution in patients with candidemia showed that the most commonly species were C. parapsilosis (45,4%), followed by C. albicans (36,4%) and C. tropicalis (18,2%); thus, we have an increase of non-albicans species. The three different species were include in 6, 3, and 4 different biotypes, respectively C. albicans, C. parapsilosis e C. tropicalis. This study emphasizes the importance of periodic evaluation of Candida species distribution especially in centers caring for patients at risk.

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.

Utilização do alcohol use disorders identification test (Audit) para identificação do consumo de álcool entre estudantes do ensino médio

Alcohol is one of the drugs most widely used among teenagers. Just recently, studies have been developed regarding the screening of use of alcohol by this population. This work aimed to investigate the use of AUDIT as a method for screening and evaluation of alcohol consumption among High School students. The sample was composed by 1227 students from two public schools, who answered to the Alcohol Use Disorders Identification Test (AUDIT) and informed their socioeconomic level, religion, and occurrence of relationship problems caused by drunkenness of family members. Using an 8 cut-off point, AUDIT has identified 17.8% of students with risk drinking. These results have revealed that AUDIT is easy to be applied and well accepted by the students. It was also evident the importance of this instrument in the follow-up programs of prevention and intervention of alcoholic beverages use.

Identificação de diterpenos clerodânicos em diferentes órgãos de Casearia sylvestris Swartz

Casearia sylvestris Swartz (Salicaceae) is a tree or shrub distributed widely in Brazil, where it is used in popular medicine. Several bioactive clerodane diterpenes typical of Casearia have been isolated from this species (e.g. casearins and casearvestrins). The main objective of this study was to identify clerodane diterpenes in various organs of C. sylvestris, using chromatographic and spectroscopic analytical techniques. The extracts of the different plant parts were analyzed by thin layer chromatography, high performance liquid chromatography with diode array detector and 1H nuclear magnetic resonance. In the chromatographic analysis, clerodane diterpenes isolated from C. sylvestris were used as standards, including rel-19Sacetóxi-18R- butanoilóxi-18,19- epóxi -6S -hidróxi -2R-(2-metilbutanoilóxi) -5S, 8R, 9R, 10S -cleroda-3,13(16),14-triene, isolated for the first time from the stems. Phytochemical profiles of the organs were produced, which indicated the presence of clerodane diterpenes in all parts of the plant, notably in the leaves. The results also suggest that the main clerodane diterpenes in the stems, flowers and roots had conjugated double-bond patterns that differed from those found in the leaves.

This paper aims to present the Critical Success Factors in the implementation of a Digital Factory project in a Brazilian company. These factors were identified by an exploratory survey on the implementation of Enterprise Resource Planning and Product Lifecycle Management among other systems. Following this identification, the factors were prioritized using the Delphi Method and the Analytic Hierarchy Process; this evaluation was carried out by professionals from enterprises which implement Digital Factory projects, in Brazil and abroad. Nine factors were identified. The five main priorities were: Continuous Support and Commitment from Top Management; Comprehensive Business Reengineering; Skilled and Experienced Partners; Participation and Commitment of Users; and Appropriate Role of the Project Manager.

Mapeamento de Paleosuperfícies associadas a identificação de depósitos supérgenos de cobre como ferramenta de exploração mineral na região de Itapeva e Ribeirão Branco- Vale do Ribeira, estado de São Paulo, Brasil

A few examples of supergene ore formation and their interaction with morphogenesis (palaeosurfaces) and weathering mineralogy are discussed. Geomorphological and mineralogical records to characterize palaeosurfaces associate the weathering of primary minerals and their relationship with concentrations of cooper and iron ore deposits in southeastern state of São Paulo, Brazil. We have distinguished two palaeosurfaces generated by several weathering phases and controlled by the geological framework. The first and oldest upper palaeosurfaces (900 - 1000 m a.s.l.), situated in Riberão Branco (Alto do Brancal), were developed on silico-limestones. It is formed by typical iron laterites enriched by secondary products of cooper. The second and younger level palaeosurfaces located in Itapeva (Santa Blandina and Bairro do Sambra). This palaeosurface is formed by copper percolating through the weathered rock (saprolite). Other features can be observed like neo-formed products in laterites. They are classified into two types: clay like silico- cupriferous products (with noticeable amounts of iron) and copper minerals (crysocolla, in their flat slopes). These features allowed the presence of copper ores and their morphogenesis control will help in the exploration and prospecting of supergene ore mineral.

Identificação de paleocanais na região da confluência entre os rios Ivaí e Paraná com o uso de dados de sensoriamento remoto e reconhecimento de fácies sedimentares

The confluence of Ivaí River together with the Paraná one is located near Icaraíma city on the Northwest of Paraná State. In this region, several paleochannels showed quaternary dynamic of Ivaí and Paraná Rivers floodplain. The aim of study was to apply multispectral indices and a data transformation of Landsat 5 TM data, associated with fieldwork and sedimentary facies to identify paleochannels. The results of the Normalized Difference Vegetation, Normalized Difference Water e Modificated Normalized Difference Water indices did not show satisfactory gains. However, the Tasseled Cap Wetness has provided an important gain of information on recognizing paleochannels facies. Through the remote sensing results sediment cores were realized and the sedimentary facies showed its correspondence with remote sensing interpretation.

Identificação de espécies fúngicas nas onicomicoses do idoso institucionalizado

BACKGROUND: Superficial fungal infections are caused by dermatophytes, yeasts or filamentous fungi. They are correlated to the etiologic agent, the level of integrity of the host immune response, the site of the lesion and also the injured tissue. OBJECTIVE: The purpose of this study is to isolate and to identify onychomycosis agents in institutionalized elderly (60 years old +). METHODS: The identification of the fungi relied upon the com-bined results of mycological examination, culture isolation and micro cultures observation under light microscopy from nail and interdigital scales, which were collected from 35 elderly with a clinical suspicion of onychomycosis and a control group (9 elderly with healthy interdigital space and nails). Both groups were insti-tutionalized in two nursing homes in Sao Bernardo do Campo, SP, Brazil. RESULTS: The nail scrapings showed 51.40% positivity. Of these, dermatophytes were found in 44.40% isolates, 27.78% identified as Trichophyton rubrum and 5.56% each as Trichophyton tonsurans, Trichophyton mentagrophytes and Microsporum gypseum. The second more conspicuous group showed 38.89% yeasts: 16.67% Candida guilliermondii, 11.11% Candida parapsilosis, 5.56% Candida glabrata, and 5.56% Trichosporon asahii. A third group displayed 16.70% filamen-tous fungi, like Fusarium sp, Aspergillus sp and Neoscytalidium sp (5.56% each). The interdigital scrapings pre-sented a positivity rate of 14.29%. The agents were coincident with the fungi that caused the onychomycosis. In the control group, Candida guilliermondii was found at interdigital space in one person. CONCLUSION: Employing a combination of those identification methods, we found no difference between the etiology of the institutional-ized elderly onychomycosis from that reported in the literature for the general population. © 2013 by Anais Brasileiros de Dermatologia.

Identificação precoce do risco para transtornos da atenção e da leitura em sala de aula

In this his study the accuracy was investigated of collective pedagogical activities, based on phonological judgments by matching figures and figures to spoken words, to identify students at risk for reading and/or attention disorders. Forty-five second graders (mean age of 7 years, 29 males) were divided into two groups, a control group, without reading difficulties (n=32), and an at-risk group, with reading difficulties (n=13). The low-achievement on these collective activities, defined by scores more than 1.65 SD below the mean of the control group, presented good sensitivity (true positives) and specificity (true negatives) in the early identification of at risk students.
