In this review article, the authors contextualize the contemporary practice of medical tourism in terms of the concept of worldmaking, which was introduced (in this journal) with two articles a year or two ago by Hollinshead. Here, the authors first contextualize medical tourism in terms of "worldmaking" per medium of the observations of the corporeal realms identified by Alexis de Tocqueville almost 200 years ago. In 1835, de Tocqueville wrote with enthusiasm tinged with nostalgic regret about the new world of American democracy that he then saw as the world of the future. A serious rupture in history took place of which he became a most relevant critic. But there have been (according to Mainil, Platenkamp, and Meulemans) many ruptures since then: that is, there have been short periods of "in-between worlds" that became ever more anchored in the timeline of Western history. Today, they argue that tourism as a field of expertise, practice, and knowledge is intertwined with several other networks of expertise. It is responsible (itself) for many small "ruptures" in these modern times. Mass tourism can be seen as such a shift. Sustainable tourism and the attention paid to climate change would be another such shift. And the authors of this review argue that an interesting and deep-seated case in this regard is medical tourism. They argue here that medical tourism has a great deal of worldmaking capacity, especially by means of the Internet and international marketing tools. It arises in the interstices of the interacting networks of a global world. It crosses borders in line with emerging power structures in a global network, but it also meets local resistance or regional obstacles that are related to other networks. In between these worlds of human experience, various interactions of perspectives on the concept of health itself come to the surface. Within the field of medical tourism different stakeholders play a role in a worldmaking process. Our reviewers from the Low Countries thereby argue that medical tourism itself is responsible for a Tocquevillean rupture within and across our global network society. In their view, medical tourism also constitutes a new hybrid-that is, as a hybrid medical paradigm that seems to be appearing within the performative and productive world of tourism.

Light profoundly impacts many aspects of human physiology and behaviour, including the synchronization of the circadian clock, the production of melatonin, and cognition. These effects of light, termed the non-visual effects of light, have been primarily investigated in laboratory settings, where light intensity, spectrum and timing can be carefully controlled to draw associations with physiological outcomes of interest. Recently, the increasing availability of wearable light loggers has opened the possibility of studying personal light exposure in free-living conditions where people engage in activities of daily living, yielding findings associating aspects of light exposure and health outcomes, supporting the importance of adequate light exposure at appropriate times for human health. However, comprehensive protocols capturing environmental (e.g., geographical location, season, climate, photoperiod) and individual factors (e.g., culture, personal habits, behaviour, commute type, profession) contributing to the measured light exposure are currently lacking. Here, we present a protocol that combines smartphone-based experience sampling (experience sampling implementing Karolinska Sleepiness Scale, KSS ratings) and high-quality light exposure data collection at three body sites (near-corneal plane between the two eyes mounted on spectacle, neck-worn pendant/badge, and wrist-worn watch-like design) to capture daily factors related to individuals’ light exposure. We will implement the protocol in an international multi-centre study to investigate the environmental and socio-cultural factors influencing light exposure patterns in Germany, Ghana, Netherlands, Spain, Sweden, and Turkey (minimum n = 15, target n = 30 per site, minimum n = 90, target n = 180 across all sites). With the resulting dataset, lifestyle and context-specific factors that contribute to healthy light exposure will be identified. This information is essential in designing effective public health interventions.

Objectives: Decline in the performance of instrumental activities of daily living (IADL) and mobility may be preceded by symptoms the patient experiences, such as fatigue. The aim of this study is to investigate whether self-reported non-task-specific fatigue is a long-term risk factor for IADL-limitations and/or mobility performance in older adults after 10 years. Methods: A prospective study from two previously conducted cross-sectional studies with 10-year follow-up was conducted among 285 males and 249 females aged 40–79 years at baseline. Fatigue was measured by asking “Did you feel tired within the past 4 weeks?” (males) and “Do you feel tired?” (females). Self-reported IADLs were assessed at baseline and follow-up. Mobility was assessed by the 6-minute walk test. Gender-specific associations between fatigue and IADL-limitations and mobility were estimated by multivariable logistic and linear regression models. Results: A total of 18.6% of males and 28.1% of females were fatigued. After adjustment, the odds ratio for fatigued versus non-fatigued males affected by IADL-limitations was 3.3 (P=0.023). In females, the association was weaker and not statistically significant, with odds ratio being 1.7 (P=0.154). Fatigued males walked 39.1 m shorter distance than those non-fatigued (P=0.048). For fatigued females, the distance was 17.5 m shorter compared to those non-fatigued (P=0.479). Conclusion: Our data suggest that self-reported fatigue may be a long-term risk factor for IADL-limitations and mobility performance in middle-aged and elderly males but possibly not in females.
