OBJECTIVES The purpose of this study is to verify how accurately wearable devices measure energy expenditure while walking outdoors.METHODS A total of 20 people, 10 healthy males and 10 females, participated in the study. After approval by the Institutional Review Board of Pusan National University, the experiment was conducted with the consent of the subject. All subjects wore four wearable devices (Fitbit Surge, Android Phone, iPhone, pedometer) and a portable gas analyzer simultaneously and walked on flat, downhill and uphill road respectively. All subjects repeated these experiments on each slope three times. The validity was verified through correlation analyses and paired <i>t</i>-test between the energy expenditure measured by the wearable devices and by a portable gas analyzer.RESULTS Under all three road slopes (flat, downhill, uphill road), the energy expenditure as measured by iPhone, Android phones, and pedometer significantly correlated with the portable gas analyzer. However, all three devices were significantly overestimated or underestimated the energy expenditure as compared to the gas analyzer under all three road slopes. Fitbit Surge did not correlate with the gas analyzer for measuring energy expenditure under any conditions, and significantly overestimated energy expenditure.CONCLUSION The validity of energy expenditure measurement during outdoor activities using wearable devices is still low, and more valid motion detection sensors and algorithms need to be developed.

Background With the global proliferation of the novel COVID-19 disease, conventionally conducting institutional review board (IRB) meetings has become a difficult task. Amid concerns about the suspension of drug development due to delays within IRBs, it has been suggested that IRB meetings should be temporarily conducted via the internet. Objective This study aimed to elucidate the current status of IRB meetings conducted through web conference systems. Methods A survey on conducting IRB meetings through web conference systems was administered to Japanese national university hospitals. Respondents were in charge of operating IRB offices at different universities. This study was not a randomized controlled trial. Results The survey was performed at 42 facilities between the end of May and early June, 2020, immediately after the state of emergency was lifted in Japan. The survey yielded a response rate of 74% (31/42). Additionally, while 68% (21/31) of facilities introduced web conference systems for IRB meetings, 13% (4/31) of the surveyed facilities postponed IRB meetings. Therefore, we conducted a further survey of 21 facilities that implemented web conference systems for IRB meetings. According to 71% (15/21) of the respondents, there was no financial burden for implementing these systems, as they were free of charge. In 90% (19/21) of the facilities, IRB meetings through web conference systems were already being conducted with personal electronic devices. Furthermore, in 48% (10/21) of facilities, a web conference system was used in conjunction with face-to-face meetings. Conclusions Due to the COVID-19 pandemic, the number of reviews in clinical trial core hospitals has decreased. This suggests that the development of pharmaceuticals has stagnated because of COVID-19. According to 71% (15/21) of the respondents who conducted IRB meetings through web conference systems, the cost of introducing such meetings was US $0, showing a negligible financial burden. Moreover, it was shown that online deliberations could be carried out in the same manner as face-to-face meetings, as 86% (18/21) of facilities stated that the number of comments made by board members did not change. To improve the quality of IRB meetings conducted through web conference systems, it is necessary to further examine camera use and the content displayed on members’ screens during meetings. Further examination of all members who use web conference systems is required. Our measures for addressing the requests and problems identified in our study could potentially be considered protocols for future IRB meetings, when the COVID-19 pandemic has passed and face-to-face meetings are possible again. This study also highlights the importance of developing web conference systems for IRB meetings to respond to future unforeseen pandemics.

Related Increase

SummaryWe studied the effect of acute exercise on the ability of thrombin to activate plasma factor VIII (FVIII) activity in 20 healthy males. The subject showed an average exercise-related increase in FVIII activity of 54.5±8.2% over pre-exercise FVIII activity (p<0.001). When exposed to the same concentration of thrombin, post-exercise FVIII activity showed greater enhancement than pre-exercise FVIII activity: 157.1±12.8% increase in activity versus 117.3±9.9%, respectively (p<0.01). The degree of the potentiated thrombin effect in post-exercise samples relative to pre-exercise samples was linearly correlated with the degree of the exercise-related increase in FVIII activity. Taken together with our previous observations that the extent of thrombin enhancement of FVIII activity varies inversely with the mole ratio of FVIII/von Willebrand factor subunits to thrombin, these findings imply that release of FVIII does not occur during exercise, and that the exercise-related increase in FVIII activity results primarily, if not completely, from activation of already circulating but inactive FVIII.

The Impact

Abstract Introduction We evaluated the effectiveness of New Orientation for Reducing Threats to Health from Secretive-problems That Affect Readiness (NORTH STAR), a community assessment, planning, and action framework to reduce the prevalence of suicidality, substance problems, intimate partner violence, and child abuse. Materials and Methods One-third of U.S. Air Force bases worldwide were randomly assigned to NORTH STAR (n = 12) or an assessment-and-feedback-only condition (n = 12). Two Air Force-wide, cross-sectional, anonymous, web-based surveys were conducted of randomly selected samples assessing risk/protective factors and outcomes. This study was reviewed and approved by the institutional review board at the investigators’ university and by the institutional review board at Fort Detrick. Results NORTH STAR, relative to control, bases experienced a 33% absolute risk reduction in hazardous drinking rates and cumulative risk, although, given the small number of bases, these effects were not statistically significant. Conclusions Given its relatively low cost, use of empirically supported light-touch interventions, and emphasis on sustainability with existing resources, NORTH STAR may be a useful system for prevention of a range of adult behavioral health problems that are difficult to impact.
