The influence of burden of care and perceived stigma on expressed emotions of relatives of stable persons with schizophrenia in Nigerian semi-urban/urban settings

RESUMO: Schizophrenia’s burden defines experience of family members and is associated with high level of distress. Courtesy stigma, a distress concept, worsens caregivers’ burden of care and impacts on schizophrenia. Expressed emotion (EE), another family variable, impacts on schizophrenia. However, relationship between EE, burden of care and stigma has been little explored in western literature but not in sub-Saharan Africa particularly Nigeria. This study explored the impact of burden of care and courtesy stigma on EE among caregivers of persons with schizophrenia in urban and semi-urban settings in Nigeria. Fifty caregivers each from semi-urban and urban areas completed a socio-demographic schedule, family questionnaire, burden interview schedule and perceived devaluation and discrimination scale. The caregivers had a mean age of 42 (± 15.6) years. Majority were females (57%), married (49%), from Yoruba ethnic group (68%), monogamous family (73%) and Christians (82%). A higher proportion of the whole sample (53%) had tertiary education. Three out of ten were sole caregivers. Seventy three (73%) lived with the person they cared for. The average number of hours spent per week by a caregiver with a person with schizophrenia was 35 hours. The urban sample had significantly higher proportion of carers with high global expressed emotion (72.7%) than the semi-urban sample (27.3%). The odds of a caregiver in an urban setting exhibiting high expressed emotion are 4.202 times higher than the odds of caregiver in a semi-urban setting. Additionally, there was significance difference between the urban and semi-urban caregivers in discrimination dimension. High levels of subjective and objective burden were associated with high levels of critical comments. In conclusion, this study is the first demonstration of urban-semi-urban difference in expressed emotion in an African country and its findings provide further support to hypothesized relationship between components of EE and burden of care.

Epidemiologic studies of chagas' disease in the urban zone of Teresina. State of Piauí, northeastern Brazil

The triatomine species Rhodnius nasutus and Triatoma pseudomaculata were captured on palm trees Orbignya martiana "babaçu ", in the urban zone of Teresina. This kind of palm tree is largely distributed in Piauí State. The predominant species was R. nasutus; the young in stars predominated. The infestation index of palm trees and the infection index of triatomines by flagellates were 96.0 ana 29.1%, respectively. Marsupiais, bats and a rodent were captured in palm trees. The flagellates found in both triatomines ana marsupiais were morphologically and biologically indistinguishable from Trypanosoma cruzi. Forty seven percent (481/1,025) of triatomines were found concentrated in six palm trees where marsupiais circulated. Of the total of 1,025 triatomines 230 (22%) were infected by flagellates and 53.0% (123/230) of these infected triatomines were present in the same six palm trees. No evidence of triatomine domiciliation or human transmission was observed in the houses in the vicinity of palm trees. The results suggest that marsupiais play an important role in the life-cycle of T. cruzi in this region. The natural focus of Chagas' disease, demonstrated in the present study could represent a potential epidemiological threat.

The palm tree Copernicia cerifera (carnaúba) as an ecotope of Rhodnius nasutus in rural areas of the State of Piauí Northeastern Brazil

The C. cerifera palm tree (carnaúba) is widely distributed in the Northeastem Brazil, including the State of Piauí. This investigation revealed that R. nasutus is the ortly triatomine species captured on that palm tree, in five different localities. 78% of palm trees were infested with triatomines, and 4.0% were infected with flagellates morphologically and biologically indistinguishable from Trypanosoma cruzi. Birds, rodents and marsupials were found as major blood meai sources for R. nasutus.

Ecologia domestica de la tripanosomiasis americana: perfil alimentario del triatoma infestans en un area rural de la província de Santiago del Estero, Argentina

Se describen los resultados entomológicos de un estúdio sobre transmiswn del Tripanosoma cruzi realizado en un caserío rural de Argentina. Se determino la prevalencia de infección elperfil alimentario de los Triatoma infestans domiciliados, relacionándose su densidad con el tipo de vivienda. Seis de las 18 viviendas estudiadas eran nuevas o mejoradas y en 16 los habitantes aplicaban hexaclorociclohexano. La menor densidad de vinchucas correspondió a las casas higiénicas o mejoradas con tratamiento químico, Los ranchos tratados presentaron un número de insectos 10 veces menor que un rancho no tratado, indicando la efectividad del control autogestado. Se hallaron T. infestans en el 100% de los dormitorios pero en sólo el 53% de los localesperidomiciliarios. Un 39% de las vinchucas intradomiciliarias estaban infectadas. El 96% de los insectos de dormitorios se alimentaron sobre hombre, perro, polloygato, siendo el índice afinidad para el perro 13 veces superior al correspondiente al hombre. Se discute la importancia epidemiológica de la concentración de vectores dentro de los dormitorios y su asociación trófica con los perros convivientes, nsí como la necessidad de combinar la mejora de vivienda con educación sanitaria.

Epidemiologia da doença de Chagas na zona rural do Município de Teresina-Piauí, Brasil

Na área rural do município de Teresina-Piauí, foram capturados 129 triatomíneos distribuídos em (a) ecótopos artificiais: habitações (1 Triatoma brasiliensis, 1 Panstrongylus geniculatus, 1 Rhodnius pictipes e 1 Rhodnius prolixusj e galpão abandonado (7 Rhodnius nasutusj e (b) ecótopos naturais: Orbignya martiana (41 Rhodnius neglectus, 33 Rhodnius prolixus e 41 Rhodnius nasutus,) e Copernicia cerifera (3 Rhodnius neglectus,). Cerca de 22,6% dos triatomíneos capturados estavam infectados por flagelados, sendo 30% no ambiente artificial e 21,9% no ambiente natural. Dos 28 mamíferos capturados e examinados, 7 Didelphis aibiventris, 2 Rattus rattus e 1 Tamandua tetradacty la apresentavam-se positivos para flagelados. Os flagelados encontrados nos triatomíneos e nos mamíferos eram semelhantes ao Trypanosoma cruzi. Das 123 reações sorológicas, por imunojluorescência indireta, realizadas na população, duas (1,6%) foram reativas.

Prevalência da esquistossomose mansoni e de parasitoses intestinais em escolares da área rural do Município de Jaboticatubas, MG, 1992-1993

Estagiários do Internato Rural da Faculdade de Medicina da UFMG realizaram levantamento da prevalência da esquistossomose mansoni e de parasitoses intestinais em 20 escolas da área rural do município de Jaboticatubas, MG. Foi feita avaliação sumária das condições de habitação e saneamento, e os escolares foram submetidos a exame clínico e parasitológico de fezes. Observou-se que 15,43% dos escolares apresentaram ovos de S. mansoni nas fezes, o que representou a parasitose de maior prevalência. Foram encontrados 13,76% de exames com a presença de G. lamblia; 12,89% de S. stercoralis; 11,13% de A. lumbricoides; 9,96% de ancilostomideos; 9,57% de E. histolytica, tendo os outros parasitas apresentado prevalências inferiores às citadas. Todas as crianças que apresentaram ovos de parasitas nas fezes foram tratadas. Os resultados encontrados mostram que a esquistossomose mansoni é um grave problema de saúde pública e que medidas na área do saneamento básico se fazem necessárias para controle da endemia.
