RESUMO

AIMS: The purpose of the present study was to elucidate the presence of human herpesvirus 6A (HHV-6A), HHV-6B and HHV-7 in samples of the uterine cervix through detection of viral DNA. We analysed normal tissues, samples with low-grade squamous intraepithelial lesions (LSILs) and high-grade squamous intraepithelial lesions (HSILs). We correlated the presence of HHV-6 and HHV-7 with the finding of human papillomavirus (HPV) in mucosal samples. METHODS: Cervical samples were examined and grouped as follows: group 1 (n=29), normal cytology; group 2 (n=61), samples with LSIL; group 3 (n=35), samples with HSIL. Molecular biology examinations were performed in all samples to detect HHV-6, HHV-7 and HPV DNA and to typify HHV-6 species. RESULTS: Group 1: normal cytology and HPV (-): HHV-6: 6.8% (2/29), HHV-7: 79.3% (23/29); group 2: LSIL and HPV (-): HHV-6: 93.1% (27/29), HHV-7: 96.5% (28/29); LSIL and HPV (+): HHV-6: 0% (0/32), HHV-7: 90.6% (29/32); group 3: HSIL and HPV (-): HHV-6: 20% (2/10), HHV-7: 70% (7/10); HSIL HPV (+): HHV-6: 12% (3/25), HHV-7: 68% (17/25). HHV-6A DNA was not detected in any samples. CONCLUSIONS: (1) Both HHV-6 and HHV-7 infect the mucosal cells of the cervix with higher prevalence of HHV-7. (2) The higher prevalence of HHV-6 in LSIL HPV (-) samples compared with those with normal cytology indicates that it constitutes a possible risk factor for atypia production. (3) The presence of HHV-7 in all samples questions its role in the production of atypia. (4) The finding of HHV-6 and HHV-7 suggests that the cervical mucosa is a possible transmission pathway for these viruses.

RESUMO

BACKGROUND: Salmonella enterica subsp. enterica serovar Abortusequi (S. Abortusequi) is a serotype restricted to equines, which produces abortion outbreaks. Nowadays the disease is being reported in different countries including Argentina thus generating an important impact in the equine industry. Molecular characterization of the 95 kb virulence plasmid and the spvC gene of S. Abortusequi demonstrated their importance in the pathogenicity of the serotype. In the last decades, high clonality of S. Abortusequi was identified in Japan, Mongolia and Croatia. OBJECTIVES: The aim of this work was to characterize S. Abortusequi isolates obtained in Argentina between 2011 and 2016 by virulence-gene profiling and pulsed-field gel electrophoresis. STUDY DESIGN: Case report. METHODS: S. Abortusequi isolates were studied by virulence-gene profiling and pulsed-field gel electrophoresis. RESULTS: Four virulence profiles and nine pulsed-field gel electrophoresis pulsotypes were identified among the 27 isolates included in the study. Different strains were found in the same outbreak and/or farm suggesting the presence of different sources of infection or mutation of isolates. MAIN LIMITATIONS: The number of related and nonrelated strains. More isolates may be necessary for a more intensive study. CONCLUSIONS: Most strains presented the same virulence profile, being positive for all the studied genes except gipA and sopE1, which are involved in intestinal virulence. Only few isolates showed different results in the same outbreak or farm. Unlike other studies, our results demonstrate a considerable diversity of S. Abortusequi pulsed-field gel electrophoresis pulsotypes, which suggests that different sources of infection may be involved within the same outbreak.

RESUMO

Este artigo se propõe a analisar a situação da psicanálise nos cursos de psicologia das universidades do Rio de Janeiro, estabelecendo uma comparação com o caso de Buenos Aires. Para tal fim, utiliza um método de análise que implica construção documental, entrevistas e estudo teórico sobre a história e a atualidade da psicologia e da psicanálise nessas cidades. Entende-se que, além da chamada "crise" da psicanálise, ela mantém uma posição predominante nesses cursos. Espera-se que este trabalho contribua para uma discussão contextualizada dos cursos de psicologia em suas revisões curriculares.(AU)


We aim to analyse the situation of psychoanalysis in psychology undergraduate courses from universities of Rio de Janeiro, comparing these with the ones from Buenos Aires. For that purpose, we use a method of analysis that involves documental construction, interviews and theoretical study on the past history and the present reality of psychology and psychoanalysis in those cities. We understand that, besides the so-called "crisis" of psychoanalysis, this theoretical orientation maintains a predominant position in those courses. We expect that this work contributes to a contextualized discussion of psychology undergraduate courses and their curricular revisions.(AU)

RESUMO

OBJETIVO: Compartir la estrategia de gestión del conocimiento en el marco del acceso abierto implementada en el Hospital. METODOLOGÍA: Frente a la necesidad de gestionar el conocimiento, los dos métodos para implementar el acceso abierto en el hospital son: la vía verde, el autoarchivo de contenidos en el Repositorio Digital del Hospital, y en segundo lugar la vía dorada, la publicación en acceso abierto de la Revista del Hospital El Cruce. Se documenta la evolución por medio del análisis de los indicadores disponibles en Google Analytics. RESULTADOS: Al analizar los indicadores de usuarios, usuarios nuevos y sesiones, se identifica un incremento superior al 80% en cantidad de usuarios y sesiones en los últimos 12 meses. Hay una importante distribución mundial en la difusión del conocimiento generado en el hospital. Esto se debe a la indización de la Revista del Hospital en la iniciativa regional LILACS y a la infraestructura tecnológica disponible. CONCLUSIONES: la gestión de conocimiento en el marco del acceso abierto forma parte de las actividades estratégicas que se orientan a promover el desarrollo de actividades de asistencia, de investigación, de docencia y la consolidación como hospital universitario. Los repositorios y las revistas de acceso abierto mejoran la difusión de los recursos que contienen, incrementando su visibilidad y el acceso a la producción institucional.


OBJECTIVE: To share the knowledge management strategy within the framework of openaccess implemented in the Hospital. METHODS: The two methods to implement open access in the hospital are: The greenway, the self-archiving of contents in the Hospital's Digital Repository and the golden route the open access publication of the El Cruce Hospital Journal. The evolution is documented through the analysis of the indicators available in Google Analytics. RESULTS: In the indicators of users, new users and sessions, there is an increase of more than 80% in the number of users and sessions in the last 12 months. There is an important worldwide distribution in the dissemination of knowledge generated in the hospital. This is due to the indexing of the Hospital Journal in the LILACS regional initiative and the available technological infrastructure. CONCLUSIONS: Knowledge management within the framework of open access is part of the strategic activities aimed at promoting the development of assistance, research, teaching and consolidation activities as a university hospital. Repositories and open access journals improve the dissemination of the resources they contain, increasing their visibility and access to institutional production.

RESUMO

Objetivo: Analizar el manejo intraquirúrgico y los resultados posquirúrgicos asociados a la extubación temprana en los pacientes sometidos a cirugía reparadora de tetralogía de Fallot en un hospital público argentino. Métodos: Se realizó una revisión retrospectiva de los expedientes clínicos de los pacientes a quienes se les practicó cirugía para corrección de tetralogía de Fallot. Se incluyeron en el análisis un total de 38 expedientes que cumplieron con los criterios de inclusión establecidos en el protocolo para la revisión retrospectiva. Resultados: El 16% fue extubado de manera temprana. Milrinona fue la única droga que mostró diferencias en los pacientes a quienes se extubó de manera temprana (p = 0,01). El tiempo de circulación extracorpórea, el de clampaje aórtico, la transfusión con crioprecipitados, la saturación de la presión de oxígeno, y el hematocrito al finalizar el procedimiento quirúrgico no evidenciaron diferencias (p > 0,05). En el período posquirúrgico, la estadía en UTI fue más corta en los pacientes que fueron extubados de manera temprana (p = 0,0007), pero no hubo diferencias en la estadía hospitalaria total (p = 0,26). Conclusiones: La extubación temprana en la institución si bien resultó de baja frecuencia ha demostrado ser una alternativa segura y eficaz para disminuir la estancia en UTI de estos pacientes


Objective: To assess surgical management and postoperative results associated with early extubation in patients undergoing tetralogy of Fallot corrective surgery at a public hospital in Argentina. Methods: A retrospective review was made from clinical records from patients who underwent corrective surgery for tetralogy of Fallot. A total of 38 clinical records that met the inclusion criteria for the retrospective review were included in the analysis. Results: 16% were extubated early. Milrinone was the only drug that showed differences in patients who were extubated early (p = 0.01). Extracorporeal circulation time, aortic clamping time, transfusion with cryoprecipitates, saturation of oxygen pressure, and haematocrit at the end of the surgical procedure showed no differences (p > .05). In the postoperative period, the ICU stay was shorter for the patients who were extubated early (p = 0.0007), but there were no differences in the total hospital stay (p = 0.26). Conclusions: Early extubation in the institution, although found to be low frequency, has proved as a safe and effective alternative to shorten these patients’ stay in ICU

RESUMO

The responses of organisms to organic farming depend on the taxonomic group and landscape complexity. Following the intermediate landscape complexity hypothesis, organic farming can compensate for the lack of complexity in simple landscapes. Argentinian farmlands are simple with large fields and scarce linear habitat array, and conventional agriculture is almost the only agriculture practice. We hypothesize that there is an interaction effect of landscape complexity and farming practices on occupancy and species richness of small mammals in farmland of central Argentina. We selected circular landscapes under organic farming and low- and high-intensity conventional farming and quantified heterogeneity in each landscape considering different cover types (crops, resting plots, fallow land, border habitats, grasslands and man-made structures). We used multi-species occupancy models accounting for multiple seasons with a Bayesian approach to make the estimates. Landscapes under organic farms had the highest level of landscape heterogeneity. In simple Argentinian farmlands, organic farming benefited species richness and occupancy of all small mammal species. Some management strategies used in organic farming (wide and vegetated border habitats, diversity in types of production, winter cover crops, natural or semi-natural patches) should be taken into account to increase landscape complexity in conventional farming.

RESUMO

Metanteon poirieri sp. nov. (Hymenoptera: Dryinidae: Anteoninae) is described from New Caledonia. The genus Metanteon Olmi, 1984, was known only from the southern region of Argentina and Chile. The unique species attributed previously to this genus is M. aerias (Walker, 1839), collected in Chile by Charles Darwin during his famous trip on the HMS Beagle. M. aerias is associated only with leafhoppers feeding on Southern Beeches (Nothofagus spp.), a genus of Nothofagaceae including species of trees and shrubs native to the southern Hemisphere in southern South America (Argentina, Chile) and Australasia (east and southeast Australia, New Zealand, New Guinea and New Caledonia). Like Nothofagus, Metanteon is a transantarctic organism.

RESUMO

Two new species of cecidomyiids were identified on Prosopis caldenia Burkart (Fabaceae) in Argentina: Rhopalomyia caldeniae Cornejo Martínez sp. nov., as the inducer of bivalve leaf galls, and the inquiline Dasineura oportunista Cornejo Martínez sp. nov. These galls are composed of the partial coalescence of two contiguous pinnulae that delimit a single larval chamber, where both species develop. Seven other species were reared from these galls as parasitoids and inquilines.

RESUMO

Three new species of free-living marine nematodes of the genus Metoncholaimus are described from San Matías gulf (Río Negro, Argentina). Metoncholaimus sanmatiensis sp. n. is characterized by large body size, long spicules, small gubernaculum, presence of long setose pre- and postcloacal genital sensilla and presence of precloacal pores. Metoncholaimus perdisus sp. n. is characterized by small-sized body, short spicules, small gubernaculum, presence of long setose pre- and postcloacal genital sensilla and presence of pre- and postcloacal pores. Metoncholaimus paracavatus sp. n. is closely related to Oncholaimus cavatus but can be considered as a new Metoncholaimus species based on the presence of gubernaculum and the morphology of the demanian system. A compendium of all valid species, including new species, is given.

RESUMO

Knowledge of the oribatid mite community from Patagonian steppe is scarce compared with other environments, such as the Andean-Patagonian forest. In the present research we identified oribatid mites under different environmental conditions: two Patagonian steppe types (grass and shrub), two soil characteristics (bare and covered soil) and two different seasons (autumn and spring). A total of 42 species/morphospecies were found, 13 were new records for Chubut and one was a new record for Argentina. In view of its ecological role in soil formation, it is fundamental that knowledge about this fauna is enhanced in order to provide baselines for study and to aid further understanding about its ecology.

RESUMO

Neognathophausia ingens (Dohrn, 1870) is a bathypelagic crustacean distributed worldwide. In the western Atlantic it has been recorded off the La Plata region, Argentina, and off the coast of Brazil, from the state of Bahia to Rio de Janeiro. We provide new records of N. ingens from the state of Rio Grande do Sul, Brazil, about 1188 km south of its previous distribution limit off Brazil, filling the gap between the central West Atlantic and Argentina. Five specimens were analyzed and drawings for all body regions and appendages are presented. Mandible, thoracopods 2, 4, 5, 6 and 8 and pleopods are illustrated and described for the first time. An updated synonym list and a distribution map for this species in Brazil are provided.

RESUMO

Thraulodes Ulmer, 1920 is one of the most abundant and widespread genera of Leptophlebiidae represented by 66 species (Barber-James et al. 2013; Gonçalves et al. 2013; Lima et al. 2013; Souto et al. 2014; Zúñiga et al. 2015; Boldrini et al. 2018; Campos Mariano 2019). Its distribution extends from Central Argentina in the Neotropics to the Neartic Region. For Brazil, 23 species are known (Salles Boldrini 2019), but only seven species are known from both adult and nymphal stages: T. bonito Gonçalves, Da-Silva Nessimian; T. cochunaensis Domínguez; T. daidaleus Traver Edmunds; T. jones Gonçalves, Da-Silva Nessimian; T. itatiajanus Traver Edmunds; T. schlingeri Traver Edmunds and T. traverae Thew (Thew 1960; Traver Edmunds 1967; Domínguez 1987; Lopes et al. 2003; Gonçalves et al. 2010; Gonçalves et al. 2013).

RESUMO

A detailed morphological comparison was carried out among specimens of several samples of Archaebranchinecta Rogers Coronel, 2011 from the Altiplano of Peru, Bolivia, and Argentina. Surprisingly, striking differences were found between Peruvian samples collected near the western shore of Lake Titicaca, and those from Bolivia taken southwardly, near the east coasts of River Desaguadero and Lake Poopó. Accordingly, the new species Archaebranchinecta aimara sp. nov. is described, representing the second specific entity of a genus that so far included only A. pollicifera (Harding, 1940). The main differential features between both species include: (a) size and shape of the three processes of basal segment of the male second antenna; (b) shape and protrusion degree of the pair of medioventral bulges in the male genital segments; (c) presence or absence of strong ventrolateral spine on the second genital segment of female; and (d) presence or absence of a pair of ventrolateral outgrowths in the brood pouch. This research contributes to our understanding of the biodiversity and endemism of the unique Altiplano region of South America.

RESUMO

The stoneflies of the family Gripopterygidae have a Gondwanan distribution (Australian, Neotropical, and Andean regions) and include about 300 species in five recognized subfamilies. The subfamily Gripopteryginae is restricted to the Neotropics and the Andean regions of South America, including 15 genera and about 80 species. Tupiperla Froehlich, with 20 species, is the largest genus among the South American Gripopteryginae. The genus has been recorded from Brazil, Paraguay, and northeastern Argentina. In Brazil, Tupiperla has been recorded from southern, southeastern, and the mountainous areas of central and northeastern, primarily from streams of the Atlantic Forest. We studied specimens of Tupiperla collected from the Atlantic Forest of southern Brazil. Herein, five new species of Tupiperla are described: T. pinhoi sp. nov., T. serrulata sp. nov., T. pessacqi sp. nov., T. ubuntu sp. nov., and T. zwicki sp. nov.

RESUMO

Knowledge on the hydrological evolution of the Neotropical region was used along with the current distribution of the anablepid species to investigate the historical biogeography of this family. Areas of endemism were delimited by endemicity analysis resulting in seven individual areas of endemism and three consensus areas located in northwestern Argentina, southern Brazil, and northern South America. These areas were discussed in the context of anablepid species diversification, especially for the genus Anableps and the subgenera Jenynsia and Plesiojenynsia. The existence of areas of endemism for the family analyzed reveals an intimate association with historical events that occurred in the geological evolution of South America, which can be associated with the main diversification patterns and historical hypotheses in the context of Neotropical freshwater fishes biogeography.
