Education in Global Health Radiology

Radiologists and radiology professionals have noted the gaps in diagnostic and interventional imaging access worldwide as documented by the World Health Organization. Since global health focuses on issues that transcend national boundaries, emphasizes solutions that often require global cooperation, and is multidisciplinary, then the concept of radiology education in global health should consider this broader context of international partnership and collaboration. There are several models in place for education in the global health setting with emphasis on radiology. This chapter discusses faculty exchanges, scholarly collaboration, partnership, formal education, online education as a tool, integration of global health concepts into radiology curricula, and socially responsible collaboration. Regardless of the type of model used, educational goals and objectives should be based on initial assessment data and address the appropriate needs. Curricula should be established in partnership with all stakeholders and with consideration for ethical best practices, continuous evaluation and improvement of the program, and open communication among stakeholders

Recent advances of marine ornamental fish larviculture: broodstock reproduction, live prey and feeding regimes, and comparison between demersal and pelagic spawners

Marine ornamental fish are a key component of the multimillion‐dollar marine aquarium trade industry, a controversial industry due to current heavy reliance on wild‐collected specimens. Aquaculture of marine ornamental fish is considered as a sustainable alternative, but it is still in the early stage of development. This review focuses on the current state of marine ornamental fish aquaculture, by covering topics on reef fish reproductive biology in captivity, traditional and novel live feeds, feeding regimes and visual environment in larviculture. Where possible, major differences between demersal and pelagic spawners are compared and discussed. Overall, for many ornamental fish species, natural spawning can be achieved in a captive environment without the use of hormone induction; however, sex identification and successful pairing for reef fish species could be a challenge. With the use of both traditional (rotifers and Artemia) and novel live feeds (e.g. marine copepods and ciliates), a range of breakthroughs in larval rearing of both demersal and pelagic spawning ornamental fish species have been achieved in recent years, although larval survival varies. To further improve the larval rearing success of marine ornamental fish, this review suggests that future research should focus on optimizing the use of live feed in terms of both quality and quantity, and establishment of well‐defined species‐specific larval feeding regime, as well as providing appropriate rearing condition through improved manipulation of light conditions and the 'greenwater' techniques in larval rearing
