Seeking treatment for symptomatic malaria in Papua New Guinea
Background: Malaria places a significant burden on the limited resources of many low income countries. Knowing more about why and where people seek treatment will enable policy makers to better allocate the limited resources. This study aims to better understand what influences treatment-seeking behaviour for malaria in one such low-income country context, Papua New Guinea (PNG). Methods: Two culturally, linguistically and demographically different regions in PNG were selected as study sites. A cross sectional household survey was undertaken in both sites resulting in the collection of data on 928 individuals who reported suffering from malaria in the previous four weeks. A probit model was then used to identify the factors determining whether or not people sought treatment for presumptive malaria. Multinomial logit models also assisted in identifying the factors that determined where people sought treatments. Results: Results in this study build upon findings from other studies. For example, while distance in PNG has previously been seen as the primary factor in influencing whether any sort of treatment will be sought, in this study cultural influences and whether it was the first, second or even third treatment for a particular episode of malaria were also important. In addition, although formal health care facilities were the most popular treatment sources, it was also found that traditional healers were a common choice. In turn, the reasons why participants chose a particular type of treatment differed according to the whether they were seeking an initial or subsequent treatments. Conclusions: Simply bringing health services closer to where people live may not always result in a greater use of formal health care facilities. Policy makers in PNG need to consider within-country variation in treatment-seeking behaviour, the important role of traditional healers and also ensure that the community fully understands the potential implications of not seeking treatment for illnesses such as malaria at a formal health care facility.Carol P Davy, Elisa Sicuri, Maria Ome, Ellie Lawrence-Wood, Peter Siba, Gordon Warvi, Ivo Mueller and Lesong Conte
A communal catalogue reveals Earth's multiscale microbial diversity
Our growing awareness of the microbial world's importance and diversity contrasts starkly with our limited understanding of its fundamental structure. Despite recent advances in DNA sequencing, a lack of standardized protocols and common analytical frameworks impedes comparisons among studies, hindering the development of global inferences about microbial life on Earth. Here we present a meta-analysis of microbial community samples collected by hundreds of researchers for the Earth Microbiome Project. Coordinated protocols and new analytical methods, particularly the use of exact sequences instead of clustered operational taxonomic units, enable bacterial and archaeal ribosomal RNA gene sequences to be followed across multiple studies and allow us to explore patterns of diversity at an unprecedented scale. The result is both a reference database giving global context to DNA sequence data and a framework for incorporating data from future studies, fostering increasingly complete characterization of Earth's microbial diversity.Peer reviewe

Health and the social power of women
The relationship between women's social status and the survival chances of their children is explained and illustrated with examples. When women (and girls) have low status, relatively little social investment is made in them, and this is reflected in girls' and boys' differential mortality rates. Several health-related social investment indicators are given, and matched against children's mortality patterns by ecological regions of Africa and Asia. The cultural propensity to invest in girls (nutrition, education, etc.) and their resultant survival chances, are explained by ecology which in past centuries has largely determined agricultural economies that either had a high demand for female labour or did not. In the former, women are more likely to control the wealth they produce and use it for transactions that put others in their social debt, thus growing in social power. Policy implications of planning and implementing primary health care in these different types of societies are explored.
Primary health care in Sierra Leone
Two pilot primary health care programmes are compared. One is primarily concerned with covering the national population by the year 2000; the other is more concerned with community participation and culturally-appropriate health care organization. Strengths and weaknesses of the two pilot programmes are assessed in relation to national financial constraints, epidemiological patterns, and the socio-cultural structure of rural chiefdoms. The comparison concludes with specific recommendations for a national programme which incorporates the best of both pilot programmes.
