Prevention of transfusional Trypanosoma cruzi infection in Latin America

Trypanosoma cruzi is a protozoan infection widely spread in Latin America, from Mexico in the north to Argentina and Chile in the south. The second most important way of acquiring the infection is by blood transfusion. Even if most countries of Latin America have law/decree/norms, that make mandatory the screening of blood donors for infectious diseases, including T. cruzi (El Salvador and Nicaragua do not have laws on the subject), there is usually no enforcement or it is very lax. Analysis of published serologic surveys of T. cruzi antibodies in blood donors done in 1993, indicating the number of donors and screening coverage for T. cruzi in ten countries of Central and South America indicated that the probability of receiving a potentially infected transfusion unit in each country varied from 1,096 per 10,000 transfusions in Bolivia, the highest, to 13.02 or 13.86 per 10,000 transfusions in Honduras and Venezuela respectively, where screening coverage was 100%. On the other hand the probability of transmitting a T. cruzi infected unit was 219/10,000 in Bolivia, 24/10,000 in Colombia, 17/10,000 in El Salvador, and around 2-12/10,000 for the seven other countries. Infectivity risks defined as the likelihood of being infected when receiving an infected transfusion unit were assumed to be 20% for T. cruzi. Based on this, estimates of the absolute number of infections induced by transfusion indicated that they were 832, 236, and 875 in Bolivia, Chile and Colombia respectively. In all the other countries varied from seven in Honduras to 85 in El Salvador. Since 1993, the situation has improved. At that time only Honduras and Venezuela screened 100% of donors, while seven countries, Argentina, Colombia, El Salvador, Honduras, Paraguay, Uruguay and Venezuela, did the same in 1996. In Central America, without information from Guatemala, the screening of donors for T. cruzi prevented the transfusion of 1,481 infected units and the potential infection of 300 individuals in 1996. In the same year, in seven countries of South America, the screening prevented the transfusion of 36,017 infected units and 7, 201 potential cases of transfusional infection.

Plasticity in sex allocation in the plant Mercurialis annua is greater for hermaphrodites sampled from dimorphic than from monomorphic populations.

Plants are notoriously variable in gender, ranging in sex allocation from purely male through hermaphrodite to purely female. This variation can have both a genetic and an adaptive plastic component. In gynodioecious species, where females co-occur with hermaphrodites, hermaphrodites tend to shift their allocation towards greater maleness when growing under low-resource conditions, either as a result of hermaphrodites shifting away from an expensive female function, or because of enhanced siring advantages in the presence of females. Similarly, in the androdioecious plant Mercurialis annua, where hermaphrodites co-exist with males, hermaphrodites also tend to enhance their relative male allocation under low-resource conditions. Here, we ask whether this response differs between hermaphrodites that have been evolving in the presence of males, in a situation analogous to that supposed for gynodioecious populations, vs. those that have been evolving in their absence. We grew hermaphrodites of M. annua from populations in which males were either present or absent under different levels of nutrient availability and compared their reaction norms. We found that, overall, hermaphrodites from populations with males tended to be more female than those from populations lacking males. Importantly, hermaphrodites' investment in pollen and seed production was more plastic when they came from populations with males than without them, reducing their pollen production at low resource availability and increasing their seed production at high resource availability. These results are consistent with the hypothesis that plasticity in sex allocation is enhanced in hermaphrodites that have likely been exposed to variation in mating opportunities due to fluctuations in the frequency of co-occurring males.

Sexual protection behavior in HIV-positive gay men: testing a modified information-motivation-behavioral skills model.

This study on determinants of sexual protection behavior among HIV-positive gay men used the empirically tested information-motivation-behavioral skills (IMB) model. HIV-specific variables were added to the model to determine factors decisive for condom use with steady and casual partners. Data were collected using an anonymous, standardized self-administered questionnaire. Study participants were recruited at HIV outpatient clinics associated with the Eurosupport Study Group and the Swiss HIV Cohort Study. To identify factors associated with condom use, backward elimination regression analyses were performed. Overall, 838 HIV-infected gay men from 14 European countries were included in this analysis. About 53% of them reported at least one sexual contact with a steady partner; 62.5% had sex with a casual partner during the last 6 months. Forty-three percent always used condoms with steady partners and 44% with casual partners. High self-efficacy and subjective norms in favor of condom-use were associated with increased condom use with casual and steady partners, whereas feeling depressed was associated with decreased condom use with casual partners. Condoms were used less often with HIV-positive partners. Self-efficacy as an important behavioral skill to perform protection behavior was influenced by lower perceived vulnerability, higher subjective norms, and more positive safer sex attitudes. The IMB-model constructs appeared to be valid; however, not all the model predictors could be determined as hypothesized. Besides the original IMB constructs, HIV-specific variables, including sexual partners' serostatus and mental health, explained condom use. Such factors should be considered in clinical interventions to promote "positive prevention."

Tecla d'Iconi, més enllà de la llegenda : estudi del paper desenvolupat per la dona en el cristianisme primitiu a través de la protagonista dels Actes de Pau i Tecla

El cristianisme, en els seus inicis, significà per la dona la possibilitat de triar un destí diferent al del matrimoni i la maternitat que li deparava la societat greco-romana. Tanmateix, en el procés d'institucionalització de la nova religió (s. I-IV), la dona, que en les primitives comunitats cristianes havia ocupat llocs de responsabilitats al costat dels seus companys masculins, va quedar relegada al desenvolupament de tasques assistencials. Els canvis experimentats pel rol femení durant aquest període es manifestaran en les transformacions operades a través de la literatura en la figura de Tecla d'Iconi (santa Tecla), un personatge intemporal, tan capaç de representar els diferents arquetips de dona ideal que ha creat l'Església cristiana, com les ànsies emancipadores d'alguns col·lectius feministes.

La representació de la dona en les pintures de Goya : Reflexe d'una realitat social?

Treball de recerca que pretén respondre les següents preguntes: La visió de Goya sobre l'univers femení, i que plasma en les seves pintures, correspon amb la realitat social de les dones de la seva època? Es diu que el segle XVIII va ésser el segle de les dones, però és això realment cert? Va ser el segle de les dones o bé el segle d'algunes dones? A través de dos itineraris paral·lels: la literatura d'una banda i les arts plàstiques de l'altra, s'explorarà la naturalesa d'aquest segle. La comparació de l'anàlisi documental i de dades iconogràfiques potser ens podran donar una resposta.

Espais femenins en l'obra de Paul Gauguin

La societat actual figura arrelada a un discurs sobre el femení, que desenvolupat durant el segle XVIII s'ha anat obrint camí insistentment a través de les imatges. A través de l'obra del pintor Paul Gauguin aquest treball presten mostrar que el confinament de la dona a l'espai domèstic i la pretesa relació d'aquesta amb altres elements és fruit de la mateixa ideologia que confina a la dona a l'espai privat i a l'home a l'espai públic.

North South Survey of Children's Height, Weight and Body Mass Index, 2002

As part of a North South Survey of Childrens Oral Health conducted in Ireland in 2001/’02 [1], the heights and weights of a representative sample of children and adolescents age 4-16 years was measured. Data were collected by 34 teams of trained and calibrated dentists and dental nurses for 17,518 children aged 4-16 in the Republic of Ireland (RoI) and 2,099 in Northern Ireland (NI). This report presents the results of the study which provide a baseline measurement of Childrens height and weight against which future change can be measured. By comparing these data with international norms we can estimate the current prevalence of overweight and obesity among children and adolescents in Ireland.

The policy-making structure of European regulatory networks and the domestic adoption of standards

European regulatory networks (ERNs) constitute the main governance instrument for the informal co-ordination of public regulation at the European Union (EU) level. They are in charge of co-ordinating national regulators and ensuring the implementation of harmonized regulatory policies across the EU, while also offering sector-specific expertise to the Commission. To this aim, ERNs develop 'best practices' and benchmarking procedures in the form of standards, norms and guidelines to be adopted in member states. In this paper, we focus on the Committee of European Securities Regulators and examine the consequences of the policy-making structure of ERNs on the domestic adoption of standards. We find that the regulators of countries with larger financial industries tend to occupy more central positions in the network, especially among newer member states. In turn, network centrality is associated with a more prompt domestic adoption of standards.

Travellers and substance use in Ireland: Recommendations for drug and alcohol policy

The Traveller community was traditionally protected from drug use by distinct traditional anti-drug norms and potent family networks within their ‘separateness’ from the ‘settled’ community. Estimations of Traveller substance use remain clouded due to lack of ethnic monitoring in drug reporting systems, and poor service utilization by Travellers. This article draws on a Traveller and substance use regional needs analysis in Ireland, comprising 12 Traveller focus groups and 45 interviews with key stakeholders. Drug activity in terms of both drug dealing and drug use among Travellers is increasing in recent years [Van Hout, M.C. (2009a). Substance misuse in the traveller community: A regional needs assessment. Western Regional Drug Task Force. Series 2. ISBN 978-0-9561479-2-9].   Traditional resiliency factors are dissipating in strength due to increased Traveller housing within marginalized areas experiencing drug activity and increased levels of young Travellers encountering youth drug use within school settings, by way of their attempts ‘to fit in’ and integrate with their ‘settled peers’ [Van Hout, M.C. (2009b). Irish travellers and drug use – An exploratory study. Ethnicity and Inequalities in Health and Social Care, 2(1), 42–49]. Fragmentation of Traveller culture is occurring as Travellers strive to retain their identity within the assimilation process into modern sedentarist Irish society. Treatment and outreach policies need to protect Traveller identity by reducing discriminatory experiences, promoting cultural acceptance with service staff and addressing literacy, implementing peer led approaches and offering flexible therapy modalities.This resource was contributed by The National Documentation Centre on Drug Use.

WHO health topic: women's health.

Being a man or a woman has a significant impact on health, as a result of both biological and gender-related differences. The health of women and girls is of particular concern because, in many societies, they are disadvantaged by discrimination rooted in sociocultural factors. For example, women and girls face increased vulnerability to HIV/AIDS. Some of the sociocultural factors that prevent women and girls to benefit from quality health services and attaining the best possible level of health include: * unequal power relationships between men and women; * social norms that decrease education and paid employment opportunities; * an exclusive focus on women’s reproductive roles; and * potential or actual experience of physical, sexual and emotional violence. While poverty is an important barrier to positive health outcomes for both men and women, poverty tends to yield a higher burden on women and girls’ health due to, for example, feeding practices (malnutrition) and use of unsafe cooking fuels (COPD).This resource was contributed by The National Documentation Centre on Drug Use.

Global regulation of the knowledge-based economy: The rise of standards in educational services

This article examines the extent and limits of non-state forms of authority in international relations. It analyses how the information and communication technology (ICT) infrastructure for the tradability of services in a global knowledge-based economy relies on informal regulatory practices for adjustment of ICT-related skills. Companies and associations provide training and certification programmes as part of a growing market for educational services setting their own standards. The existing literature on non-conventional forms of authority in the global political economy has emphasised that the consent of actors subject to informal rules and explicit or implicit state recognition remains crucial for the effectiveness of those new forms of power. However, analyses based on a limited sample of actors tend toward a narrow understanding of the issues and fail to fully explore the differentiated space in which non-state authority is emerging. This paper examines the form of authority underpinning the global knowledge-based economy within the broader perspective of the issues likely to be standardised by technical ICT specification, the wide range of actors involved, and the highly differentiated space where standards become authoritative. The empirical findings highlight the role of different private actors in establishing international educational norms in this field. They also pinpoint the limits of profit-oriented standard-settings, notably with regard to generic norms.
