Hepatitis C in a sample of pregnant women in Switzerland: seroprevalence and socio-demographic factors

PRINCIPLES: The aim of this study was to determine the prevalence of hepatitis C (HCV) infection in a sample of pregnant women living in Switzerland in 1990-1991, in order to complement existing data in various populations. METHODS: Blood samples were collected from women from consecutive births in obstetric wards in public hospitals of 23 Swiss cantons over a one-year period. They were tested, among other things, for the presence of hepatitis C virus antibodies (anti-HCV). Statistical analyses were done to explore the association of demographic variables with anti-HCV. RESULTS: The study included a total of 9,057 women of whom 64 tested positive for anti-HCV, resulting in a crude prevalence of 0.71%. Prevalence varied by age and was highest in the 25-29-year age-group (0.90%). 43/5,685 Swiss women were HCV seropositive (0.76%) compared with 21/3,372 non-Swiss women (0.62%). Stratified analysis showed a significant association between anti-HCV and anti-HBc antibody positivity in Swiss (adjusted OR [aOR] 23, 95% CI 12-43) and non-Swiss nationals (aOR 3.3, 95% CI 1.3-8.3). CONCLUSIONS: The prevalence of anti-HCV antibodies in the early 1990s was <1% in this sample of pregnant women in Switzerland and was associated with age, nationality and the presence of anti-HBc antibodies, a marker of exposure to hepatitis B virus. These results are in accordance with those from other published European studies. If an effective intervention to prevent vertical transmission becomes available, information on the current prevalence of HCV in pregnant women would be needed in order to assess how screening recommendations should be modified.

SOCIO-ENVIRONMENTAL FACTORS ASSOCIATED WITH THE DISTRIBUTION OF DRACUNCULUS MEDINENSIS (GUINEA WORM DISEASE) AND SUGGESTED METHODS FOR CONTROL, IBARAPA, NIGERIA, 1982 (AFRICA)

A population-based cross-sectional survey of socio-environmental factors associated with the prevalence of Dracunculus medinensis (guinea worm disease) was conducted in Idere, a rural agricultural community in Ibarapa, Oyo state, Nigeria, during 1982.^ The epidemiologic data were collected by household interview of all 501 households. The environmental data were collected by analysis of water samples collected from all domestic water sources and rainfall records.^ The specific objectives of this research were to: (a) Describe the prevalence of guinea worm disease in Idere during 1982 by age, sex, area of residence, drinking water source, religion and weekly amount of money spent by the household to collect potable drinking water. (b) Compare the characteristics of cases with non-cases of guinea worm in order to identify factors associated with high risk of infection. (c) Investigate domestic water sources for the distribution of Cyclops. (d) Determine the extent of potable water shortage with a view to identifying factors responsible for such shortage in the community. (e) Describe the effects of guinea worm on school attendance during 1980/1982 school years by class and location of school from piped water supply.^ The findings of this research indicate that during 1982, 31.8 percent of Idere's 6,527 residents experienced guinea worm infection, with higher prevalence of infection recorded in males in their most productive years and females in their teenage years. The role of sex and age to risk of higher infection rate was explained in the context of water related exposure and water intake due to dehydration from physical occupational actitives of subgroups.^ Potable water available to residents was considerably below the minimum recommended by WHO for tropical climates, with sixty-eight percent of water needs of the residents coming from unprotected surface water which harbour Cyclops, the obligatory intermediate host of Dracunculus medinensis. An association was found between periods of relative high density of Cyclops in domestic water and rainfall.^ Impact of guinea worm infection on educational activities was considerable and its implications were discussed, including the implications of the research findings in relation to control of guinea worm disease in Ibarapa. ^

Intervención judicial y contexto socio cultural : la puesta en marcha de un trabajo interdisciplinario "in situ"

Partiendo de una noción de acceso a la justicia, que no se restringe únicamente al acceso formal de los ciudadanos al sistema judicial y al adecuado ejercicio de derechos ante los Tribunales de Justicia, sino que también abarca la Prevención y Promoción de Derechos, la Solución Colaborativa de Conflictos, la Revisión y Propuesta de las Actuaciones Públicas mediante Acciones de Interés Público y Propuestas Legislativas; se implementaron, desde la Institución Judicial (Juzgado de Familia de Tupungato), acciones en el marco de buenas prácticas que se sustentas en tres ejes: Construcción de Ciudadanía, Desarrollo Humano Sustentable y Redes Sociales. Las mismas tienden a fortalecer las conexiones entre estructuras formales e informales de la comunidad, a fin de proveer efectivamente el Acceso a la Justicia a grupos que de otra manera podrían estar excluidos de ella y a la vez favorecer el empoderamiento de los grupos vulnerables en la búsqueda de soluciones a situaciones injustas en el ámbito de los procesos tramitan por ante los Juzgados de Familia. En dicho marco, el Juzgado referido puso en marcha un Juzgado Móvil que plantea una metodología de abordaje interdisciplinario, donde la intervención del Trabajador Social resulta relevante.

An international study on the impact of cultural factors on the prevalence of family-owned firms. ACES Working Papers, August 2010

A key question in international corporate governance is why certain in ownership types are prevalent in different countries around the world (La Prota et al., 1999). In this study, we provide an answer for the prevalence of the family-owned firms in 42 countries by examining key characteristics of culture. We show that family-ownership is positively correlated with power distance (PD), in-group collectivism (CI) and, insignificantly, with uncertainty avoidance (UA). Our study makes a contribution to the field since previous research used religion and language as umbrella constructs for culture, while we pinpoint specific cultural dimensions.
