Thus far, ecophysiology research has predominantly been conducted within controlled laboratory-based environments, owing to a mismatch between the recording technologies available for physiological monitoring in wild animals and the suite of behaviours and environments they need to withstand, without unduly affecting subjects. While it is possible to record some physiological variables for free-living animals using animal-attached logging devices, including inertial-measurement, heart-rate and temperature loggers, the field is still in its infancy. In this opinion piece, we review the most important future research directions for advancing the field of ‘physiologging’ in wild animals, including the technological development that we anticipate will be required, and the fiscal and ethical challenges that must be overcome. Non-invasive, multi-sensor miniature devices are ubiquitous in the world of human health and fitness monitoring, creating invaluable opportunities for animal and human physiologging to drive synergistic advances. We argue that by capitalizing on the research efforts and advancements made in the development of human wearables, it will be possible to design the non-invasive loggers needed by ecophysiologists to collect accurate physiological data from free-ranging animals ethically and with an absolute minimum of impact. In turn, findings have the capacity to foster transformative advances in human health monitoring. Thus, we invite biomedical engineers and researchers to collaborate with the animal-tagging community to drive forward the advancements necessary to realize the full potential of both fields. This article is part of the theme issue ‘Measuring physiology in free-living animals (Part II)’.
Parr, Nicole, Matt Wilkes, and Lucy Alice Hawkes. Natural climbers: insights from avian physiology at high altitude. High Alt Med Biol. 20:427-437, 2019.-High altitudes are physiologically challenging: the hypobaric hypoxia, cold, and increased ultraviolet radiation mean humans ascending to high altitude faster than they acclimatize risk life-threatening illnesses. Despite such challenges, birds can thrive at high altitudes and some even complete metabolically costly migrations across the world's highest mountain ranges. We outline the aspects of avian anatomy and physiology that confer advantages at each level of the oxygen transport cascade and compare them with those of human and nonhuman mammals. We also discuss additional adaptations that have been described for high-altitude specialist species of birds and how these are mirrored in high-altitude adapted mammals.
Telemedicine potentially offers enormous value to expeditions to remote environments. For healthcare professionals, telemedicine can provide access to specialist advice. Where no healthcare professionals are present, telemedicine may be the sole source of expert care. This systematic review appraises and summarizes the current literature regarding telemedicine in patient management on expeditions to remote locations and identifies areas for future research. MEDLINE and EMBASE were systematically searched for relevant articles from 1980 through February 2018. Data were handled according to the PRISMA process and analyzed using type-specific critical appraisal checklists where possible. Two hundred twenty-five articles were identified, 33 of which were included in this systematic review. They encompassed a variety of remote environments, including maritime (13), polar (9), mountainous (5), jungle (1), and multiple austere environments (6). Although some environments were better reported than others, many overarching concepts were generalizable. Through channels of communication that included telephone, radio, videoconferencing, and email, telemedicine has been used effectively in a range of environments to initiate treatment, follow up with patients, and determine the appropriateness of evacuation. Telementoring, in which a remote expert guides a local care provider in performing a procedure or task, is a promising aspect of telemedicine that is currently being developed. As technology advances, the scope of telemedicine will continue to expand. However, each new telemedical development must be shown to do more than simply function in a remote environment. Instead, new technologies should be tested for improved patient, practitioner, or expedition outcomes, within a telemedical system.
To support leaders and those involved in providing medical care on expeditions in wilderness environments, the Faculty of Pre-Hospital Care (FPHC) of The Royal College of Surgeons of Edinburgh convened an expert panel of leading healthcare professionals and expedition providers. The aims of this panel were to: (1) provide guidance to ensure the best possible medical care for patients within the geographical, logistical and human factor constraints of an expedition environment. (2) Give aspiring and established expedition medics a ‘benchmark’ of skills they should meet. (3) Facilitate expedition organisers in selecting the most appropriate medical cover and provider for their planned activity. A system of medical planning is suggested to enable expedition leaders to identify the potential medical risks and their mitigation. It was recognised that the scope of practice for wilderness medicine covers elements of primary healthcare, pre-hospital emergency medicine and preventative medicine. Some unique competencies were also identified. Further to this, the panel recommends the use of a matrix and advisory expedition medic competencies relating to the remoteness and medical threat of the expedition. This advice is aimed at all levels of expedition medic, leader and organiser who may be responsible for delivering or managing the delivery of remote medical care for participants. The expedition medic should be someone equipped with the appropriate medical competencies, scope of practice and capabilities in the expedition environment and need not necessarily be a qualified doctor. In addition to providing guidance regarding the clinical competencies required of the expedition medic, the document provides generic guidance and signposting to the more pertinent aspects of the role of expedition medic.Electronic supplementary materialThe online version of this article (doi:10.1186/s13728-015-0041-x) contains supplementary material, which is available to authorized users.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
