Effectiveness and Use of Avalanche Airbags in Mortality Reduction among Winter-Recreationists.
The number of backcountry skiers and snowboarder surged in the last years, especially during the COVID-19 pandemic, as ski resorts shut down. Inevitably, this led to an increase in avalanche-related injuries and death. As avalanche rescue device, avalanche airbags are increasingly becoming part of the standard winter mountaineering equipment. This study provides a review of the available data and an updated perspective on avalanche airbags, discussing their function and efficacy to reduce mortality and their limitations. ⋯ Avalanche airbags seem to be an important tool in reducing mortality in the backcountry expeditions. However, more research and standardized data collection are needed to fill the knowledge gap, and mountain communities should promote adequate education of winter-recreationists on how to prevent and react to an avalanche and on the correct use of airbags in combination with already available tools such as transceivers, probes and shovels; and manufacturing companies should ensure higher efficacy of the survival avalanche equipment for better prevention of burial, asphyxia and trauma.

Eye disease and international travel: a critical literature review and practical recommendations.
Eye diseases pose a significant public health and economic burden, particularly for travellers exposed to ocular hazards who may lack access to specialist eye care. This article offers an evidence-based review for travel-health practitioners, with a particular emphasis on ocular infections and trauma that are more prevalent among travellers. Providing an overview of these issues will allow travel health practitioners to comprehensively address ophthalmic considerations of travel. ⋯ Travel medicine practitioners should have a comprehensive understanding of the major ocular risks associated with overseas travel, including eye infections, eye injuries and solar eye damage. Further research in this area can enhance overall wellness and alleviate the burden of ocular diseases on travellers. Evidence-based guidelines based on research can also improve the quality of care and prevent long-term vision problems.

Altitude sojourns increasingly attract individuals of all ages and different health statuses due to the appeal of high-altitude destinations worldwide and easy access to air travel. The risk of acute mountain sickness (AMS) when flying to high-altitude destinations remains underemphasized. Thus, this review aims to evaluate the altitude-dependent AMS incidence depending on the mode of ascending, e.g. by air vs terrestrial travel. ⋯ Due to the short time span in going from low to high altitude, reduced acclimatization likely is the main reason for a higher AMS risk when travelling to high-altitude destinations by flight. To avoid frustrating travel experiences and health risks, appropriate and timely medical advice on how to prepare for air travel to high altitude is of vital importance. Effective preparation options include the use of modern pre-acclimatization strategies and pharmacological prophylaxis by acetazolamide or dexamethasone, or even considering alternate itineraries with more gradual ascent.

Early in the pandemic, cruise travel exacerbated the global spread of SARS-CoV-2. We report epidemiologic and molecular findings from an investigation of a cluster of travellers with confirmed COVID-19 returning to the USA from Nile River cruises in Egypt. ⋯ Nile River cruise travellers with COVID-19 introduced SARS-CoV-2 over a very large geographic range, facilitating transmission across the USA early in the pandemic. Travellers who participate in cruises, even on small river vessels as investigated in this study, are at increased risk of SARS-CoV-2 exposure. Therefore, history of river cruise travel should be considered in contact tracing and outbreak investigations.

Many travellers do not receive vaccines pre-travel. Tools such as vaccine decision aids could support informed vaccine decision-making. We aimed to characterise Australians' pre-travel vaccine attitudes, behaviours and information needs and examine the role for decision aids in travel medicine. ⋯ Health professionals play an important role in supporting pre-travel vaccine decision-making. However, our findings indicate that reliable, accurate and engaging digital resources, such as decision aids, could support travellers to make informed pre-travel vaccine decisions.
