Given the importance of Africa to studies of human origins and disease susceptibility, detailed characterization of African genetic diversity is needed. The African Genome Variation Project provides a resource with which to design, implement and interpret genomic studies in sub-Saharan Africa and worldwide. The African Genome Variation Project represents dense genotypes from 1,481 individuals and whole-genome sequences from 320 individuals across sub-Saharan Africa. Using this resource, we find novel evidence of complex, regionally distinct hunter-gatherer and Eurasian admixture across sub-Saharan Africa. We identify new loci under selection, including loci related to malaria susceptibility and hypertension. We show that modern imputation panels (sets of reference genotypes from which unobserved or missing genotypes in study sets can be inferred) can identify association signals at highly differentiated loci across populations in sub-Saharan Africa. Using whole-genome sequencing, we demonstrate further improvements in imputation accuracy, strengthening the case for large-scale sequencing efforts of diverse African haplotypes. Finally, we present an efficient genotype array design capturing common genetic variation in Africa.

The unacceptably high incidence of clinical adverse events caused by medical devices (MDs), their high recall rates, and the frequent phase out of some of the devices that pose a greater risk to health have triggered alarm concerning the long-standing weaknesses of their regulatory processes. It has long been known that regulation is not strongly associated with the existence of market failures. In this article the deficient approval process and postmarketing surveillance of MDs in the United States and Europe, as well as the causes and effects of their very serious failings, that put patient safety at serious risk, are critically reviewed. Solutions to address the urgent need to develop new regulation in the European Union are set forth as well. The fragmented MD industry is plagued with externalities. It seems that regulation is more being supplied in response to industry's demand (legislation and agencies capture) than for redistributing health and wealth. Severe adverse events associated with MD are spurring demand for regulation. Governments should promote the most risked-based, cost-effective regulations, those that pursue the interests of individuals affected, by using public and unbiased estimates of their costs and benefits, maximizing net health gains through legislation, applying clear rules of the game, and braking up the effects of the influence of interest groups., (Copyright © 2013 Elsevier Ireland Ltd.
