The fifth Millennium development Goal (MDG) calls for a reduction in the maternal mortality ratio (MMR) by 75% between 1990 and 2015, with a key indicator being the proportion of births attended to by skilled health personnel, (United Nations, 2007). In Kenya the MMR is 400 and has made insufficient progress towards improving maternal health, (UNICEF, WHO, World Bank, 2013). According to KDHS (2014), the proportion of skilled birth attendance is 46.5%, while in Kenya it is 62% against an MDG target of 90%. According to Zaers S., et al., (2008), prior experience in delivery care by skilled attendants affects …

Mammographic density (MD) is a quantitative trait, measurable in all women, and is among the strongest markers of breast cancer risk. The population-based epidemiology of MD has revealed genetic, lifestyle and societal/environmental determinants, but studies have largely been conducted in women with similar westernized lifestyles living in countries with high breast cancer incidence rates. To benefit from the heterogeneity in risk factors and their combinations worldwide, we created an International Consortium on Mammographic Density (ICMD) to pool individual-level epidemiological and MD data from general population studies worldwide. ICMD aims to characterize determinants of MD more precisely, and to evaluate whether …

Mycobacterium Tuberculosis Lineage 4 Comprises Globally Distributed And Geographically Restricted Sublineages, David Stucki, Daniela Brites, Leïla Jeljeli, Mireia Coscolla, Gunturu Revathi

Pathology, East Africa

Generalist and specialist species differ in the breadth of their ecological niches. Little is known about the niche width of obligate human pathogens. Here we analyzed a global collection of Mycobacterium tuberculosis lineage 4 clinical isolates, the most geographically widespread cause of human tuberculosis. We show that lineage 4 comprises globally distributed and geographically restricted sublineages, suggesting a distinction between generalists and specialists. Population genomic analyses showed that, whereas the majority of human T cell epitopes were conserved in all sublineages, the proportion of variable epitopes was higher in generalists. Our data further support a European origin for the most …

Co-Construction Of Consent And Counselling During Provider Initiated Counselling And Testing (Pitc) In Nairobi Kenya, Eunice Ndirangu, Evans Catrin, Kristian Pollock

School of Nursing & Midwifery, East Africa

Background: The global policy focus of today’s HIV efforts and strategies is to reverse the spread of HIV/AIDS and provide care, treatment and support. A key component of this strategy is to increase individual HIV status awareness through expansion of HIV testing and counselling (HTC). However, the numbers tested still remain and evidence suggests that there are significant missed opportunities for HIV testing in clinical settings. One key strategy to expand HTC in clinical settings has been to implement a policy of ‘provider initiated counselling and testing’ (PITC) in which all patients accessing health facilities for treatment are routinely offered …
