How conflicts of interest hinder effective regulation of healthcare: an analysis of antimicrobial use regulation in Cambodia, Indonesia and Pakistan.

BMJ Glob Health 2022 May;7(5)

Department of Global Health and Development, London School of Hygiene & Tropical Medicine, London, UK.

Background: There has been insufficient attention to a fundamental force shaping healthcare policies-conflicts of interest (COI). We investigated COI, which results in the professional judgement of a policymaker or healthcare provider being compromised by a secondary interest, in relation to antimicrobial use, thereby illuminating challenges to the regulation of medicines use more broadly. Our objectives were to characterise connections between three groups-policymakers, healthcare providers and pharmaceutical companies-that can create COI, and elucidate the impacts of COI on stages of the policy process.

Ecological speciation by sympatric host shifts in a clade of herbivorous sea slugs, with introgression and localized mitochondrial capture between species.

Mol Phylogenet Evol 2022 May 16:107523. Epub 2022 May 16.

Department of Biological Sciences, California State University, Los Angeles, CA 90032-8201, U.S.A. Electronic address:

Host shifting in insect-plant systems was historically important to the development of ecological speciation theory, yet surprisingly few studies have examined whether host shifting drives diversification of marine herbivores. When small-bodied consumers feed and also mate on a preferred host, disruptive selection can split a population into host races despite gene flow. Support for host shifts is notably lacking for invertebrates associated with macroalgae, where the scale of dispersal by planktonic larvae often far exceeds the grain of host patchiness, and adults are typically less specialized than terrestrial herbivores.
