Healing Africa? Reflections on the peace-building role of a health-based non governmental organization operating in eastern Democratic Republic of Congo.

Whilst there are convincing theoretical arguments about the peace-building potential of the health sector, case studies documenting its interventions remain limited. This article contributes to the existing 'Peace through Health' literature by considering the model of HEAL Africa, a health-based non-governmental organization operating in Eastern Congo. Several of HEAL Africa's projects seek to prevent and reduce key risk factors; for conflict, and to contribute to longer term rehabilitation. Many of these interventions are born out of HEAL's emphasis on providing emergency health care--and the neutrality, legitimacy, access and longevity which this generates. However, this focus also tends to act as a limiting factor on the application and resourcing of its conflict prevention and reconstruction efforts. Whilst this case study warns against overstating the potential role of the health sector in promoting peace, HEAL's activities provide evidence of the types of positive contributions that can be made in practice. The role of the health sector, equipped as it is with useful tools for conflict transformation, should therefore be considered more proactively by the peace-building community.

Methylation changes at NR3C1 in newborns associate with maternal prenatal stress exposure and newborn birth weight.

Early life experiences, including those in utero, have been linked to increased risk for adult-onset chronic disease. The underlying assumption is that there is a critical period of developmental plasticity in utero when selection of the fetal phenotype that is best adapted to the intrauterine environment occurs. The current study is the first to test the idea that extreme maternal psychosocial stressors, as observed in the Democratic Republic of Congo, may modify locus-specific epigenetic marks in the newborn resulting in altered health outcomes. Here we show a significant correlation between culturally relevant measures of maternal prenatal stress, newborn birth weight and newborn methylation in the promoter of the glucocorticoid receptor NR3C1. Increased methylation may constrain plasticity in subsequent gene expression and restrict the range of stress adaptation responses possible in affected individuals, thus increasing their risk for adult-onset diseases.

Mobilising indigenous resources for anthropologically designed HIV-prevention and behaviour-change interventions in southern Africa.

HIV prevention is often implemented as if African culture were either nonexistent or a series of obstacles to overcome in order to achieve an effective, gender-equitable, human rights-based set of interventions. Similarly, traditional or indigenous leaders, such as chiefs and members of royal families, have been largely excluded from HIV/AIDS responses in Africa. This qualitative study used focus group discussions and in-depth interviews with traditional leaders and 'ritual specialists' to better understand cultural patterns and ways of working with, rather than against, culture and traditional leaders in HIV-prevention efforts. The research was carried out in four southern African countries (Botswana, Lesotho, South Africa and Swaziland). The purpose was to discover what aspects of indigenous leadership and cultural resources might be accessed and developed to influence individual behaviour as well as the prevailing community norms, values, sanctions and social controls that are related to sexual behaviour. The indigenous leaders participating in the research largely felt bypassed and marginalised by organised efforts to prevent HIV infections and also believed that HIV-prevention programmes typically confronted, circumvented, criticised or condemned traditional culture. However, indigenous leaders may possess innovative ideas about ways to change individuals' sexual behaviour in general. The participants discussed ways to revive traditional social structures and cultural mechanisms as a means to incorporate HIV-prevention and gender-sensitivity training into existing cultural platforms, such as rites of passage, chiefs' councils and traditional courts.
