Interface between Intellectual Disability and Mental Health: hermeneutic review

A literature review was conducted aiming to understand the interface between the Intellectual Disability and Mental Health fields and to contribute to mitigating the path of institutionalizing individuals with intellectual deficiencies. The so-called dual diagnosis phenomenon remains underestimated in Brazil but is the object of research and specific public policy internationally. This phenomenon alerts us to the prevalence of mental health problems in those with intellectual disabilities, limiting their social inclusion. The findings reinforce the importance of this theme and indicate possible diagnostic invisibility of the development of mental illness in those with intellectual disabilities in Brazil, which may contribute to sustaining psychiatric institutionalization of this population. 

Portal cd4+ and cd8+ t lymphocyte correlate to intensity of interface hepatitis in chronic hepatitis C

BACKGROUND: The pathogenesis of chronic hepatitis C is still a matter of debate. CD4+ and CD8+ T lymphocytes (TL) are typically observed within the portal and periportal spaces of affected livers, but their functional role in hepatitis C progression has not been fully elucidated. METHODS: CD4+ and CD8+ TL were quantified by immunohistochemistry in portal and periportal spaces of 39 liver biopsies from patients with chronic hepatitis C. They were associated to demographic data, histological parameters, laboratory findings of patients and hepatitis C genotypes. RESULTS: There was high numbers of CD4+ and CD8+ TL from which the density of CD4+ T was higher than CD8+ TL in portal and periportal spaces. CD4+ and CD8+ TL were directly correlated to intensity of interface hepatitis. CD8+ TL correlated to serum enzyme levels. CONCLUSION: The high numbers of CD4+ and CD8+ TL in portal and periportal spaces and their correlation to interface hepatitis suggest that hepatitis C evolution depends on the action of intrahepatic T lymphocytes, lending support to the notion of an immune-mediated mechanism in the pathogenesis of chronic hepatitis C.

Resposta da assembleia de formigas na interface solo-serapilheira a um gradiente de alteração ambiental

O estudo objetivou avaliar a resposta da assembleia de formigas que nidificam na interface solo-serapilheira a um gradiente de alteração ambiental. O estudo foi realizado em três ambientes com diferentes usos do solo: fragmento florestal, sistema agroflorestal (SAF) e pastagem situados em região de domínio da mata atlântica no sudeste do Brasil. Em cada ambiente foram demarcadas 10 parcelas de 1 m² e todos os ninhos de formigas encontrados foram registrados. Foram encontrados 215 ninhos (103 no fragmento florestal, 64 no sistema agroflorestal e 48 na pastagem), de 31 espécies. O número acumulado de espécies foi maior no fragmento florestal que na pastagem, mas não diferiu do SAF. A composição de espécies foi diferente entre o fragmento florestal e os outros dois ambientes. A riqueza média de espécies de formigas por parcela foi maior no fragmento florestal e menor na pastagem. A quantidade de serapilheira não foi um fator importante para as diferenças na riqueza de espécies. Atividades humanas que reduzam a heterogeneidade da vegetação alteram a composição e diminuem a riqueza de espécies das assembleias de formigas.

Influenza A virus infection of healthy piglets in an abattoir in Brazil: animal-human interface and risk for interspecies transmission

Asymptomatic influenza virus infections in pigs are frequent and the lack of measures for controlling viral spread facilitates the circulation of different virus strains between pigs. The goal of this study was to demonstrate the circulation of influenza A virus strains among asymptomatic piglets in an abattoir in Brazil and discuss the potential public health impacts. Tracheal samples (n = 330) were collected from asymptomatic animals by a veterinarian that also performed visual lung tissue examinations. No slaughtered animals presented with any noticeable macroscopic signs of influenza infection following examination of lung tissues. Samples were then analysed by reverse transcription-polymerase chain reaction that resulted in the identification of 30 (9%) influenza A positive samples. The presence of asymptomatic pig infections suggested that these animals could facilitate virus dissemination and act as a source of infection for the herd, thereby enabling the emergence of influenza outbreaks associated with significant economic losses. Furthermore, the continuous exposure of the farm and abattoir workers to the virus increases the risk for interspecies transmission. Monitoring measures of swine influenza virus infections and vaccination and monitoring of employees for influenza infection should also be considered. In addition regulatory agencies should consider the public health ramifications regarding the potential zoonotic viral transmission between humans and pigs.

The peri-urban interface and house infestation with Triatoma infestans in the Argentine Chaco: an underreported process?

Peri-urban infestations with triatomine bugs, their sources and their dynamics have rarely been investigated. Here, we corroborated the reported occurrence of Triatoma infestans in a peri-urban area and in neighbouring rural houses in Pampa del Indio, in the Argentine Chaco, and identified its putative sources using spatial analysis and demographic questionnaires. Peri-urban householders reported that 10% of their premises had triatomines, whereas T. infestans was collected by timed manual searches or community-based surveillance in only nine (3%) houses. Trypanosoma cruzi-infected T. infestans and Triatoma sordida were collected indoors only in peri-urban houses and were infected with TcV and TcI, respectively. The triatomines fed on chickens, cats and humans. Peri-urban infestations were most frequent in a squatter settlement and particularly within the recently built mud houses of rural immigrants, with large-sized households, more dogs and cats and more crowding. Several of the observed infestations were most likely associated with passive bug transport from other sources and with active bug dispersal from neighbouring foci. Thus, the households in the squatter settlement were at a greater risk of bug invasion and colonisation. In sum, the incipient process of domestic colonisation and transmission, along with persistent rural-to-urban migratory flows and unplanned urbanisation, indicate the need for active vector surveillance and control actions at the peri-urban interface of the Gran Chaco.

DESENVOLVIMENTO, AUTOMAÇÃO E DESEMPENHO DE UM CONSOLIDÔMETRO COM INTERFACE HOMEM-MÁQUINA

O ensaio de consolidação preconiza a utilização de um consolidômetro. Esse equipamento, até então, não era produzido e comercializado no Brasil. Os modelos não automatizados disponíveis para importação, apesar da proposta de baixo custo, ainda são rústicos e necessitam de contínua calibração dos níveis de pressão durante a realização do ensaio. A exclusividade e intervenção de um técnico durante todo o ensaio, associada à precária coleta de dados nesses modelos, ainda são os principais fatores que têm inviabilizado a consolidação desse ensaio na ciência do solo brasileira. Como alternativa a esses problemas, este trabalho teve por objetivos desenvolver e automatizar um consolidômetro a partir de um Controlador Lógico Programável (CLP) com interface homem-máquina (IHM). O equipamento é constituído de um gabinete de metal que aloja conjuntos de dispositivos pneumáticos, eletrônico-digital e atuadores de força e posição. O funcionamento de cada dispositivo de forma isolado ou conjugado é gerenciado por meio de um software em linguagem de programação ladder, que, a partir de um CLP com IHM incorporada, possibilita armazenar instruções e implementar funções. A interface entre o PC e o consolidômetro é feita pelo software CA-Linker, v 1.0, projetado especificamente para o equipamento. O uso do CLP com IHM incorporada permitiu o desenvolvimento e a automação do consolidômetro. O desempenho e a eficiência do conjunto de dispositivos (pneumáticos, eletrônico-digital e atuadores de força e pressão) foram comprovados pelos excelentes resultados dos valores de deformação e pressão obtidos em função do tempo e, principalmente, do comportamento da curva de compressão, gerada pelos ensaios de compressão.

Yield and performance of sugarcane in on-farm interface with rubber in Brazil

Agroforestry systems are indicated as an alternative for sugarcane (Saccharum officinarum) cultivation in Piracicaba, SP, Brazil, however there are not many field experiments on plant performance under these conditions in the world. The objective of this work was to assess crop yield and partitioning in a sugarcane-rubber (Hevea brasiliensis) interface in on-farm conditions. The availability of irradiance for the crop along the interface was simulated and its effe ct over sugarcane dry matter production was tested. Crop yield was negatively affected by distance of the trees, but development and sucrose were not affected. Above ground dry matter increased from 16.6 to 51.5 t ha-1 from trees. Partitioning did not have a defined standard, as harvest index increased from 0.85 to 0.93, but specific leaf area was not significant along the transect, ranging from 13.48 to 15.73 m² kg-1. Light is the main factor of competition between the trees and the crop, but the relative importance of below ground interactions increases closer to the trees. Feasibility of the system depends on maturity of the trees and management strategies.

Utilização de uma interface do tipo "particle beam" para a obtenção de espectros de massas de compostos pouco voláteis em solução

Due to source contamination and wearing of instrument components problems caused by the direct insertion probe technique, a new way of introduction of low volatile compounds into mass spectrometer was tested. This new scheme comprises the introduction of the low volatile compounds solutions via a six port valve connected to a particle beam interface. Solutions of isatin were injected into this system and the best results were obtained with CH2Cl2, CH3OH and CH3CN. The solution inlet system has shown to be advantageous over the conventional way of direct insertion probe introduction.

Uma interface lab-made para aquisição de sinais analógicos instrumentais via porta paralela do microcomputador

A lab-made interface for acquisition of instrumental analog signals between 0 and 5 V at a frequency up to 670 kHz at the parallel port of a microcomputer is described. Since it uses few and small components, it was built into the connector of a printer parallel cable. Its performance was evaluated by monitoring the signals of four different instruments and similar analytical curves were obtained with the interface and from readings from the instrument' displays. Because the components are cheap (~U$35,00) and easy to get, the proposed interface is a simple and economical alternative for data acquisition in small laboratories for routine work, research and teaching.
