ABSTRACT The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others. publications problem uptodate up date classifications context exception (CTFB http//fauna.jbrj.gov.br/, httpfaunajbrjgovbr http //fauna.jbrj.gov.br/ , jbrj gov br (http://fauna.jbrj.gov.br/) 2015 Brazil 80 specialists 1 2024 133691 133 691 133,69 125138 125 138 125,13 82.3%, 823 82 3 (82.3% 102000 102 000 102,00 7.69%, 769 7 69 (7.69% 11000 11 11,00 . 3,567 3567 567 (3,56 2,292 2292 2 292 (2,29 1,833 1833 833 (1,83 1,447 1447 447 (1,44 1000 1,00 831 (83 628 (62 606 (60 520 (52 50 users science health biology law anthropology education others http//fauna.jbrj.gov.br/ faunajbrjgovbr //fauna.jbrj.gov.br (http://fauna.jbrj.gov.br/ 201 8 202 13369 13 133,6 12513 12 125,1 82.3% (82.3 10200 10 00 102,0 7.69% 76 6 (7.69 1100 11,0 3,56 356 56 (3,5 2,29 229 29 (2,2 1,83 183 83 (1,8 1,44 144 44 (1,4 100 1,0 (8 62 (6 60 52 (5 5 http//fauna.jbrj.gov.br (http://fauna.jbrj.gov.br 20 1336 133, 1251 125, 82.3 (82. 1020 0 102, 7.69 (7.6 110 11, 3,5 35 (3, 2,2 22 (2, 1,8 18 (1, 1,4 14 4 ( 82.

RESUMO Objetivou-se avaliar os efeitos fisiológicos, sedativos e analgésicos da administração peridural de ropivacaína isolada ou associada à morfina ou à metadona. Para tal, 24 cadelas submetidas à ovário-histerectomia receberam acepromazina, e a anestesia foi induzida e mantida com propofol e isoflurano (FiO2 = 1,0), respectivamente. De acordo com o protocolo peridural, formaram-se três grupos de igual número: GR (ropivacaína - 2,0mg/kg); GRMETA (ropivacaína - 2,0mg/kg e metadona - 0,3mg/kg) e GRMORF (ropivacaína - 2,0mg/kg e morfina - 0,1mg/kg). Registraram-se os parâmetros fisiológicos intraoperatórios e os graus de sedação e analgesia pós-operatórios. No GR constataram-se maiores médias de pressões arteriais 30 minutos após a anestesia epidural em relação ao GRMETA (sistólica e média) e ao final do procedimento cirúrgico comparativamente ao GRMORF (sistólica, diastólica e média). Não foram observadas diferenças significativas entre os grupos relativamente à analgesia e ao grau de sedação pós-operatórios. A administração epidural de ropivacaína é segura e eficaz e proporciona boa analgesia, independentemente da sua associação com morfina ou metadona.
ABSTRACT The aim of this study was to evaluate the physiological, sedative and analgesic effects of epidural administration of ropivacaine sole or associated to morphine or methadone. Twenty-four bitches were submitted to ovariohysterectomy and received acepromazine and after, propofol and isoflurane (FiO 2 = 1.0) for anesthesia induction and maintenance, respectively. Based on established epidural protocol (L7-S1), three groups were formed: GR (ropivacaine - 2.0mg/kg); GRMETA (ropivacaine - 2.0mg/kg and methadone - 0.3mg/kg) and GRMORF (ropivacaine - 2.0mg/kg and morphine - 0.1mg/kg). Intraoperative physiological parameters and degrees of postoperative sedation and analgesia were recorded. In the GR, the means of arterial pressures, 30 minutes after epidural anesthesia, were higher compared with GRMETA (systolic and mean) and, at the end of the clinical procedure, compared to GRMORF (systolic, diastolic and mean). Differences between groups were not observed for postoperative analgesia and degree of sedation. Epidural administration of ropivacaine is safe and effective and provides good analgesia regardless of its association with morphine or methadone.

Sepsis remains a major cause of morbidity and mortality worldwide, with increased burden in low- and middle-resource settings. The role of the inflammatory response in the pathogenesis of the syndrome has supported the modern concept of sepsis. Nevertheless, a definition of sepsis and the criteria for its recognition is a continuous process, which reflects the growing knowledge of its mechanisms and the success and failure of diagnostic and therapeutic interventions. Here we review the evolving concepts of sepsis, from the “systemic inflammatory response syndrome triggered by infection” (Sepsis-1) to “a severe, potentially fatal, organic dysfunction caused by an inadequate or dysregulated host response to infection” (Sepsis-3). We focused in the pathophysiology behind the concept and the criteria for recognition and diagnosis of sepsis. A major challenge in evaluating the host response in sepsis is to characterize what is protective and what is harmful, and we discuss that, at least in part, the apparent dysregulated host response may be an effort to adapt to a hostile environment. The new criteria for recognition and diagnosis of sepsis were derived from robust databases, restricted, however, to developed countries. Since then, the criteria have been supported in different clinical settings and in different economic and epidemiological contexts, but still raise discussion regarding their use for the identification versus the prognostication of the septic patient. Clinicians should not be restricted to definition criteria when evaluating patients with infection and should wisely use the broad array of information obtained by rigorous clinical observation.

RESUMO: A caprinocultura na região Nordeste do Brasil desempenha importante função socioeconômica e estratégica. A rusticidade desta atividade nesta região, aliada a sua rápida expansão em outros estados, tem gerado perdas na sua cadeia produtiva a nível regional e nacional, causadas por doenças infecciosas, destacando-se a Linfadenite Caseosa (LC), afecção amplamente difundida nos rebanhos caprinos, acarretando sérios prejuízos econômicos à atividade. Embora LC tenha sido detectada como um problema endêmico no nordeste brasileiro, uma análise abrangente e mais recente desta prevalência nos rebanhos caprinos brasileiros se faz necessária. O objetivo desse estudo foi determinar a frequência de anticorpos anti-Corynebacterium pseudotuberculosis em cinco dos nove estados que compõem a região Nordeste do Brasil. Foram processadas amostras de soro de 2571 caprinos provenientes de 218 propriedades rurais oriundas de cinco estados da região Nordeste do Brasil, coletadas entre os anos de 2010 a 2012. O diagnóstico da infecção por C. pseudotuberculosis foi realizado pela técnica de ELISA-indireto. Em 88,5% (193/218) das propriedades investigadas, pelo menos um caprino foi soropositivo para C. pseudotuberculosis, sugerindo que o agente se encontra disseminado nos rebanhos do Nordeste, com a maior prevalência encontrada no Rio Grande do Norte (94,5%) e a menor no estado de Sergipe (70,3%). Foram identificados 783 (30,4%; IC 95%=28,7-32,2%) caprinos soropositivos, com a maior prevalência entre animais encontrada no Piauí (41,4%) e a menor no estado de Sergipe (22,5%). De um total de 279 reprodutores avaliados, 106 (37,9%) resultaram soropositivos, destacando-se o Rio Grande do Norte, com 45,30%, e Piauí com 46,8% dos reprodutores positivos para LC. Das 1420 matrizes testadas, 599(42,1%) apresentaram sorologia positiva para C. pseudotuberculosis. Entre os estados esta distribuição também se manteve semelhante, destacando-se o Rio Grande do Norte, com 47,5% e Piauí com 59,5% das matrizes positivos para LC. Entre os 872 caprinos jovens avaliados, 78 (8,9%) foram soropositivos para LC, observando-se uma diferença estatística na frequência de sopositividade obtidas entre os adultos e os jovens (P<0,001). Reforça-se a necessidade do diagnóstico da enfermidade em rebanhos caprinos da região Nordeste para possível implementação de programas de controle da doença e medidas mais precisas no manejo da LC junto aos criadores de caprinos.
ABSTRACT: Goat farming in the Northeast region of Brazil plays an important socioeconomic and strategic role. The rusticity of this activity in this region, allied with its rapid expansion in other states, has caused losses in its production chain in regional and national levels, caused by infectious diseases, especially caseous lymphadenitis (CL), a widespread goat herds disease which has been causing serious economic loss to this activity. Although CL has been detected as an endemic problem in the Brazilian Northeast, a comprehensive and more recent analysis of this prevalence in Brazilian goats is necessary. The objective of this study was to determine the frequency of anti-Corynebacterium pseudotuberculosis antibodies in five of nine states of the northeast region of Brazil. Serum samples were collected from 2571 goats from 218 farms in five states in the Northeast region of Brazil, collected between 2010 and 2012. The diagnosis of C. pseudotuberculosis infection was made using the ELISA-indirect technique. In 88.5% (193/218) of the investigated properties, at least one goat was seropositive for C. pseudotuberculosis, suggesting that the agent is widespread in Northeast herds, with the highest prevalence found in Rio Grande do Norte (94.5%) and the lowest one in the state of Sergipe (70.3%). A total of 783 (30.45%; 95% CI = 28.71-32.26%) seropositive goats were found, and the highest prevalence among animals was found in Piauí (41.4%) and the lowest in the state of Sergipe (22.5%). Out of a total of 279 breeding herds, 106 (37.99%) were seropositive, standing out the Rio Grande do Norte, with a total of 45.30%, and Piauí 46.8% of positive breeding for CL. A total of the 1420 tested matrices, 599 (42.1%) presented positive serology for C. pseudotuberculosis. Among the States, this distribution also remained similar, standing out Rio Grande do Norte with 47.5%, and Piauí with 59.5% of positive matrices for CL. Among 872 young goats evaluated, 78 (8.9%) were seropositive for CL, observing a statistical difference in the frequency of soropositivity obtained between adults and young adults (P<0.001). The necessity to diagnose the disease in goat herds in the Northeast region is reinforced for the possible implementation of disease control programs and more precise measures to manage CL along with goat farmers.

Trypanosoma cruzi triggers a progressive inflammatory response affecting cardiovascular functions in humans and experimental models. Angiotensin II, a key effector of the renin-angiotensin system, plays roles in mediating hypertension, heart failure, and inflammatory responses. T. cruzi and AngII can induce inflammatory responses by releasing inflammatory mediators. The aim of this study was to evaluate systemic AngII, tumor necrosis factor (TNF), and CX3CL1 mediators in a two-kidney one-clip (2K1C) renovascular hypertension model using Wistar rats infected with T. cruzi. Our data showed an increase in serum AngII in uninfected and T. cruzi-infected rats 1 week after 2K1C surgery compared to non-2K1C (Sham) animals. The baseline systolic blood pressure was higher in both uninfected and infected 2K1C rats. Despite no difference in circulating parasites in the acute phase of infection, elevated serum TNF and CX3CL1 were observed at 8 weeks post-infection in 2K1C rats in association with higher cardiac inflammatory infiltration. In summary, AngII-induced hypertension associated with T. cruzi infection may act synergistically to increase TNF and CX3CL1 in the 2K1C rat model, thereby intensifying cardiac inflammatory infiltration and worsening the underlying inflammation triggered by this protozoan.

RESUMO: O objetivo deste estudo foi determinar a soroprevalência de lentivírus de pequenos ruminantes (LVPR) e identificar os fatores de risco para a ocorrência de caprinos e ovinos soropositivos no semiárido do Estado da Paraíba. Foram utilizados 1.733 animais, sendo 1.274 caprinos procedentes de 62 Unidades de Produção (UPs) e 459 ovinos provenientes de 32 UPs. Para o diagnóstico sorológico da infecção por lentivírus foi utilizado o teste de imunodifusão em gel de ágar (IDGA). Dos 1.274 caprinos analisados 15 (1,18%) foram soropositivos, enquanto que todos os 459 ovinos foram soronegativos. Das 62 propriedades caprinas analisadas oito (12,9%) apresentaram pelo menos um animal soropositivo. Os fatores de risco para a ocorrência de caprinos soropositivos foram área da propriedade (odds ratio = 3,28; p = 0,044), ausência de capacitação dos produtores (odds ratio = 8,29; p = 0,042) e uso de monta natural não controlada (odds ratio = 6,78; p = 0,012). Conclui-se que a infecção por lentivírus de pequenos ruminantes, demonstrada pela detecção de anticorpos, está disseminada em rebanhos caprinos do semiárido paraibano, e sugere-se o incentivo à capacitação contínua dos produtores, manutenção de reprodutores negativos ao LVPR e utilização de inseminação artificial com o intuito de evitar o contato físico entre macho e fêmeas.
ABSTRACT: The aim of this survey was to determine the seroprevalence of small ruminant lentivirus (SRLV) and to identify risk factors for the occurrence of seropositive goats and sheep in the semiarid region of Paraiba State. It were used 1,733 animals, being 1,274 goats from 62 Production Units (PU) and 459 sheep from 38 PU. For the serological diagnosis of lentivirus infection the agar gel immunodiffusion test (AGID) was used. Of the 1,274 goats 15 (1.18%) were seropositive, and all 459 sheep were seronegative. Of the 62 goat herds eight (12.9%) presented at least one seropositive animal. Risk factors for the occurrence of seropositive goats were area of the property ≤35 ha (odds ratio = 3.28; p=0.044), not training of producers (odds ratio = 8.29; p=0.042) and use of uncontrolled natural mating (odds ratio = 6.78; p=0.012). It is concluded that lentivirus infection detected by serology is spread in goat flocks in the semiarid of the State of Paraíba, and it is suggested to encourage the continous capacitation of owners, maintenance of reproducers negative for SRLV and use of artificial insemination aiming to avoid the physical contact among male and females.

This study was conducted in order to evaluate the transmission of caprine lentivirus to sheep using different experimental groups. The first one (colostrum group) was formed by nine lambs receiving colostrum from goats positive for small ruminant lentiviruses (SRLV). The second group (milk group) was established by nine lambs that received milk of these goats. Third was a control group, consisting of lambs that suckled colostrum and milk of negative mothers. Another experimental group (contact group) was formed by eight adult sheep, confined with two naturally infected goats. The groups were monitored by immunoblotting (IB), enzyme-linked immunosorbent assay (ELISA), agar gel immunodiffusion (AGID) and nested polymerase chain reaction (nPCR). All lambs that suckled colostrum and milk of infected goats and six sheep of the contact group had positive results in the nPCR, although seroconversion was detected only in three of the exposed animals, with no clinical lentiviruses manifestation, in 720 days of observation. There was a close relationship between viral sequences obtained from infected animals and the prototype CAEV-Cork. Thus, it was concluded that SRLV can be transmitted from goats to sheep, however, the degree of adaptation of the virus strain to the host species probably interferes with the infection persistence and seroconversion rate.

Resumo: O cerrado é a mais diversificada savana tropical do mundo e constitui grande importância ecológica. Ainda assim, são poucos os estudos realizados no Brasil a respeito das doenças que acometem os canídeos desse bioma, o que causa prejuízos à população de animais selvagens e à saúde pública. Essa pesquisa foi realizada com o objetivo de avaliar a ocorrência de anticorpos contra Leptospira spp. em três espécies de canídeos selvagens do cerrado brasileiro utilizando o teste de soroaglutinação microscópica (SAM). Foram testadas amostras de soro sanguíneo de 19 cachorros-do-mato (Cerdocyon thous), 14 lobos guarás (Chrysocyon brachyurus) e sete raposas-do-campo (Lycalopex vetulus) de vida livre das regiões de cerrado de Araguari e Uberlândia, MG, e Cumari, GO. Dessas 40 amostras, 14 (35%) foram soropositivas. Os sorovares detectados com maior frequência foram Copenhageni e Hardjo, porém evidenciou-se também reação aos sorovares Autumnalis, Grippotyphosa, Hbedomadis, Wolffi e Icterohaemorrhagiae. Esse trabalho foi o primeiro a relatar a presença de anticorpos anti-Leptospira spp. em L. vetulus e verificou-se que as três espécies de canídeos utilizadas nessa pesquisa podem atuar como possíveis hospedeiros de diversos sorovares de leptospiras no ambiente de cerrado.
Abstract: The Brazilian savanna, also known as Cerrado, is one of the world's richest and most ecologically invaluable tropical savanna regions. There are few studies in Brazil about the diseases that affect the wild canids of this biome, which may be harmful to wildlife populations and public health. The aim of this study was to evaluate the occurrence of antibodies against Leptospira spp. in three Cerrado wild canids species using the microscopic agglutination test (MAT). Serum samples were tested from 19 crab-eating foxes (Cerdocyon thous), 14 maned wolves (Chrysocyon brachyurus), and seven hoary foxes (Lycalopex vetulus), all free-ranging animals found in the municipalities of Araguari and Uberlândia, Minas Gerais State, and Cumari, Goiás State, Brazil. Fourteen (35%) of these samples were seropositive. The most frequent serovars detected in the samples were Copenhageni and Hardjo, but reactions to the serovars Autumnalis, Grippotyphosa, Hebdomadis, Wolffi, and Icterohaemorrhagiae also occurred. Notwithstanding other reported results, this study is the first to report the presence of antibodies against Leptospira spp. in L. vetulus. The three species of wild canids examined may act as potential hosts for several serovars of leptospira in Brazil's savanna environment.

In adults with non-promyelocytic acute myeloid leukemia (AML), high-dose cytarabine consolidation therapy has been shown to influence survival in selected patients, although the appropriate doses and schemes have not been defined. We evaluated survival after calculating the actual dose of cytarabine that patients received for consolidation therapy and divided them into 3 groups according to dose. We conducted a single-center, retrospective study involving 311 non-promyelocytic AML patients with a median age of 36 years (16-79 years) who received curative treatment between 1978 and 2007. The 131 patients who received cytarabine consolidation were assigned to study groups by their cytarabine dose protocol. Group 1 (n=69) received <1.5 g/m2 every 12 h on 3 alternate days for up to 4 cycles. The remaining patients received high-dose cytarabine (≥1.5 g/m2 every 12 h on 3 alternate days for up to 4 cycles). The actual dose received during the entire consolidation period in these patients was calculated, allowing us to divide these patients into 2 additional groups. Group 2 (n=27) received an intermediate-high-dose (<27 g/m2), and group 3 (n=35) received a very-high-dose (≥27 g/m2). Among the 311 patients receiving curative treatment, the 5-year survival rate was 20.2% (63 patients). The cytarabine consolidation dose was an independent determinant of survival in multivariate analysis; age, karyotype, induction protocol, French-American-British classification, and de novo leukemia were not. Comparisons showed that the risk of death was higher in the intermediate-high-dose group 2 (hazard ratio [HR]=4.51; 95% confidence interval [CI]: 1.81-11.21) and the low-dose group 1 (HR=4.43; 95% CI: 1.97-9.96) than in the very-high-dose group 3, with no significant difference between those two groups. Our findings indicated that very-high-dose cytarabine during consolidation in adults with non-promyelocytic AML may improve survival.

Resumo Um levantamento atualizado das plantas com sementes e análises relevantes acerca desta biodiversidade são apresentados. Este trabalho se iniciou em 2010 com a publicação do Catálogo de Plantas e Fungos e, desde então vem sendo atualizado por mais de 430 especialistas trabalhando online. O Brasil abriga atualmente 32.086 espécies nativas de Angiospermas e 23 espécies nativas de Gimnospermas e estes novos dados mostram um aumento de 3% da riqueza em relação a 2010. A Amazônia é o Domínio Fitogeográfico com o maior número de espécies de Gimnospermas, enquanto que a Floresta Atlântica possui a maior riqueza de Angiospermas. Houve um crescimento considerável no número de espécies e nas taxas de endemismo para a maioria dos Domínios (Caatinga, Cerrado, Floresta Atlântica, Pampa e Pantanal), com exceção da Amazônia que apresentou uma diminuição de 2,5% de endemicidade. Entretanto, a maior parte das plantas com sementes que ocorrem no Brasil (57,4%) é endêmica deste território. A proporção de formas de vida varia de acordo com os diferentes Domínios: árvores são mais expressivas na Amazônia e Floresta Atlântica do que nos outros biomas, ervas são dominantes no Pampa e as lianas apresentam riqueza expressiva na Amazônia, Floresta Atlântica e Pantanal. Este trabalho não só quantifica a biodiversidade brasileira, mas também indica as lacunas de conhecimento e o desafio a ser enfrentado para a conservação desta flora.
Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora.

O objetivo do presente trabalho foi investigar a conveniência do emprego de estirpes de leptospiras autóctones isoladas no Brasil, na coleção de antígenos da microtécnica de soroaglutinação microscópica (SAM) aplicada a leptospirose. Foram amostradas por conveniência 109 propriedades e 9820 bovinos, fêmeas em idade reprodutiva, distribuídos em 85 municípios, dos Estados de Goiás, Mato Grosso, Mato Grosso do Sul, Minas Gerais, Paraná, Rio Grande do Sul, Santa Catarina e São Paulo. Dos 9820 animais examinados, 5806 (59,12%) foram reagentes na SAM para pelo menos um sorovar com a coleção de 23 sorovares de referência. Com a coleção de antígenos de referência e dez estirpes autóctones houve 6400 (65,17%) reagentes, com diferença significativa entre as proporções (p=0,001). Os sorovares mais prováveis identificados com a coleção de antígenos de referência foram Hardjo (43,03%), Shermani (20 %), Wolffi (9,96%), Grippothyphosa (5,42%) e Pomona (4,28%). Com a coleção ampliada por dez estirpes isoladas no Brasil, os sorovares mais prováveis foram Hardjo (31,00%), Guaricura-M4/84 (22,50%), Shermani (15,43%), Wolffi (4,76%), Grippothyphosa (3,71%) e Autumnalis (3,24%). O sorovar Guaricura, estirpe M4/84, isolada de bovinos e búfalos no Estado de São Paulo, despontou como um dos três sorovares mais freqüentes nos Estados de Goiás, Mato Grosso, Mato Grosso do Sul, Minas Gerais e São Paulo. A introdução de estirpes autóctones na coleção de antígenos da SAM propiciou a confirmação do diagnóstico de leptospirose em 594 animais (6,00%) classificados como não reagentes pela coleção de referência (p=0,001).
The aim of this study was to investigate the adequacy of the use of autochthonous strains of leptospires isolated in Brazil, added to antigen collection of the microscopic agglutination test (MAT) applied to the diagnosis of bovine leptospirosis. By means of non-probability sampling, 109 farms and 9,820 cattle, females at reproductive age were chosen from 85 municipalities in the states of Goiás, Mato Grosso, Mato Grosso do Sul, Minas Gerais, Paraná, Rio Grande do Sul, Santa Catarina and São Paulo. Among the 9,820 examined animals, 5,806 (59.12%) were reactants at MAT for at least one serovar using the 23 reference serovars. Employing the collection of reference serovars and the ten autochthonous strains, 6,400 (65.24%) reactants and significant difference (p=0.001) was found. The most probable serovars identified by the collection of reference antigens were Hardjo (43.03%), Shermani (20%), Wolfi (9.96%), Grippothyphosa (5.42%) and Pomona (4.28%). With the collection amplified with the ten strains isolated in Brazil, the most probable serovars were Hardjo (31%), Guaricura-M4/84 (22.50%), Shermani (15.43%), Wolffi (4.76%), Grippothyphosa (3.71%) and Autumnalis (3.24%). The serovar Guaricura, strain M4/84, isolated from bovines and buffaloes in the State of São Paulo, was ranked as one of the three most probable serovars in the states of Goiás, Mato Grosso, Mato Grosso do Sul, Minas Gerais and São Paulo. The addition of autochthonous strains to the MAT antigen collection provided the confirmation of the diagnosis of leptospirosis in 594 cattle (6%) which have been classified as non-reactants by the reference collection (p=0.001).

OBJETIVO: Determinar qual combinação de testes cognitivos e avaliações do informante pode melhorar o rastreio de demência em idosos com baixo nível educacional. MÉTODO: Pacientes com demência leve a moderada (n=34) de acordo com critérios da CID-10 e DSM-III-R, e 59 controles idosos foram avaliados com o Mini-Exame do Estado Mental (MEEM) e com o "Fuld Object Memory Evaluation" (FOME). Informantes foram avaliados com o "Informant Questionnaire on Cognitive Decline in the Elderly" e a escala Bayer-Atividades da Vida Diária. RESULTADOS: Os quatro instrumentos combinados com a regra mista classificaram 100% e a regressão logística (soma ponderada) classificou 95,7% dos sujeitos. A soma ponderada teve uma área da curva ROC significativamente maior comparada ao MEEM (p=0,008) e FOME (p=0,023). A especificidade das combinações testadas foi superior ao MEEM isolado (p=0,002). CONCLUSÕES: Testes cognitivos combinados com relatos dos informantes podem melhorar o rastreio de demência leve a moderada em idosos com baixo nível educacional.
OBJECTIVE: To determine which combination of cognitive tests and informant reports can improve the diagnostic accuracy of dementia screening in low educated older people. METHOD: Patients with mild to moderate dementia (n=34) according to ICD-10 and DSM-III-R criteria and 59 older controls were assessed with the Mini-Mental State Examination (MMSE) and the Fuld Object Memory Evaluation (FOME). Informants were assessed using the Informant Questionnaire on Cognitive Decline in the Elderly and the Bayer-Activities of Daily Living Scale. RESULTS: The 4 instruments combined with the mixed rule correctly classified 100% and the logistic regression (weighted sum) classified 95.7% of subjects. The weighted sum had a significantly larger ROC area compared to MMSE (p=0.008) and FOME (p=0.023). The specificity of the tested combinations was superior to the MMSE alone (p=0.002). CONCLUSIONS: Cognitive tests combined with informant reports can improve the screening of mild to moderate dementia in low educated older people.

Allogeneic stem cell transplantation has been increasingly performed for a variety of hematologic diseases. Clinically significant acute graft-versus-host disease (GVHD) occurs in 9 to 50% of patients who receive allogeneic grafts, resulting in high morbidity and mortality. There is no standard therapy for patients with acute GVHD who do not respond to steroids. Studies have shown a possible benefit of anti-TNF-a (infliximab)for the treatment of acute GVHD. We report here on the outcomes of 10 recipients of related or unrelated stem cell transplants who received 10 mg/kg infliximab, iv, once weekly for a median of 3.5 doses (range: 1-6) for the treatment of severe acute GVHD and who were not responsive to standard therapy. All patients had acute GVHD grades II to IV (II = 2, III = 3, IV = 5). Overall, 9 patients responded and 1 patient had progressive disease. Among the responders, 3 had complete responses and 6 partial responses. All patients with cutaneous or gastrointestinal involvement responded, while only 2 of 6 patients with liver disease showed any response. None of the 10 patients had any kind of immediate toxicity. Four patients died, all of them with sepsis. Six patients are still alive after a median follow-up time of 544 days (92-600) after transplantation. Considering the severity of the cases and the bad prognosis associated with advanced acute GVHD, we find our results encouraging. Anti-TNF-a seems to be a useful agent for the treatment of acute GVHD.

Diabetic retinopathy is one of the leading causes of blindness in working-age individuals. Diabetic patients with proteinuria or those on dialysis usually present severe forms of diabetic retinopathy, but the association of diabetic retinopathy with early stages of diabetic nephropathy has not been entirely established. A cross-sectional study was conducted on 1214 type 2 diabetic patients to determine whether microalbuminuria is associated with proliferative diabetic retinopathy in these patients. Patients were evaluated by direct and indirect ophthalmoscopy and grouped according to the presence or absence of proliferative diabetic retinopathy. The agreement of diabetic retinopathy classification performed by ophthalmoscopy and by stereoscopic color fundus photographs was 95.1% (kappa = 0.735; P < 0.001). Demographic information, smoking history, anthropometric and blood pressure measurements, glycemic and lipid profile, and urinary albumin were evaluated. On multiple regression analysis, diabetic nephropathy (OR = 5.18, 95% CI = 2.91-9.22, P < 0.001), insulin use (OR = 2.52, 95% CI = 1.47-4.31, P = 0.001) and diabetes duration (OR = 1.04, 95% CI = 1.01-1.07, P = 0.011) were positively associated with proliferative diabetic retinopathy, and body mass index (OR = 0.90, 95% CI = 0.86-0.96, P < 0.001) was negatively associated with it. When patients with macroalbuminuria and on dialysis were excluded, microalbuminuria (OR = 3.3, 95% CI = 1.56-6.98, P = 0.002) remained associated with proliferative diabetic retinopathy. Therefore, type 2 diabetic patients with proliferative diabetic retinopathy more often presented renal involvement, including urinary albumin excretion within the microalbuminuria range. Therefore, all patients with proliferative diabetic retinopathy should undergo an evaluation of renal function including urinary albumin measurements.

OBJETIVO: Descrever os achados da espectroscopia de prótons (¹H-ERM) na doença de Alzheimer (DA) e no comprometimento cognitivo sem demência (CIND) em uma amostra da comunidade. MÉTODO: Foram avaliados seis pacientes com DA, sete com CIND e sete controles normais, originários da comunidade. ¹H-ERM foi realizada com voxel de 8 cm³ nas regiões temporal direita, parietal esquerda e occipital medial e estudados os metabólitos: N-acetilaspartato (NAA), creatina (Cr), colina (Cho) e mio-inositol (mI). RESULTADOS: O NAA foi maior nos indivíduos controles do que nos DA e intermediário no CIND. Análise de função discriminante mostrou que as associações Cr parietal-Cr occipital e Cr parietal-Cho occipital identificaram corretamente 92,3% da amostra comparando Controle vs DA. Na comparação Controle vs CIND O mI temporal identificou corretamente 78,6% dos indivíduos. CONCLUSÃO: A espectroscopia pode contribuir para o diagnóstico e seguimento de indivíduos com comprometimento cognitivo; avaliações de pacientes da comunidade podem revelar achados diferentes quanto à distribuição dos metabólitos cerebrais.
OBJECTIVE: To describe the proton magnetic resonance spectroscopy (¹H-ERM) data in Alzheimer's disease (AD) and Cognitive Impairment Not Dementia (CIND) in a community sample. METHOD: We investigated subjects with AD (n=6), CIND (n=7) and normal control (n=7). ¹H-ERM was performed with single voxel (8 cm³) placed in temporal, parietal e occipital regions and studied metabolites were: N-acetylaspartate (NAA), creatine (Cr), choline (Cho) and myo-inositol (mI). RESULTS: NAA concentration was higher in control subjects than AD and intermediated in CIND patients. Cho parietal plus occipital and Cr parietal plus Cho occipital classified correctly 92.3% of subjects Control vs AD. Temporal mI classified 78.6% of subjects between Control vs CIND. CONCLUSION: Spectroscopy can be used in the diagnosis and follow-up of individuals with cognitive impairment; evaluation of community subjects may show different patterns of brain metabolites distribution.
