2209-1491; ABN 29 299 823 713 Diving and Hyperbaric Medicine Volume 50 No. 1 March 2020 1 The Editor’s offering In this issue we are pleased to publish the final paper in on endothelial function. Their finding of minimal effect is a thematic series that comprises Thijs Wingelaar’s PhD interesting but should be interpreted cautiously because dissertation. Dr Wingelaar completes his PhD this month, baseline endothelial function was borderline normal prior to and such completions within our discipline are a goal that all HBOT in their cohort of subjects, and it is not known how senior academics in the field should actively strive to support. upper and lower limb endothelial function correlate in these PhD students not only conduct important work during patients. Finally, Brian Andrew and David Doolette present the course of their studies, but recent history tells us that the findings of a study to validate a US Navy air bounce dive many remain academically active in diving and hyperbaric schedule. This paper is notable in that it presents data that medicine even if not working full time in the field. Names have previously appeared in a US Navy technical report. The like Kate Lambrechts, Frauke Tillmans, Peter Buzzacott who journal takes the view that since these reports are not easily came through the PHYPODE or similar programs offering available to the general public, not externally peer reviewed PhD study continue to be active in the field (including and not searchable in the literature indexes, the distillation publishing in and/or reviewing for DHM). One benefit of of related data into a peer reviewed and indexed scientific operating in a comparatively under-researched field such as paper is a legitimate initiative. There are several similar diving and hyperbaric medicine is that there remain many reports of likely high interest to the diving community that ‘low hanging fruit’ questions that in other better funded we hope to publish in this way. fields would have been answered decades ago. It is thus a fertile field for doctoral degree study. Congratulations to There are two review articles. Peter Westerweel and Dr Wingelaar and his supervisors (Professor Rob van Hulst colleagues review diving with hypertension and anti- and others). hypertensive drugs. This is of high practical relevance to the many readers of the journal who perform assessments This issue also contains papers from two senior clinicians of suitability for diving. There is also a review of wearable who are also doctoral research degree candidates. sensors in
