Impact of DST (Daylight Saving Time) on Major Trauma: A European Cohort Study

(1) Background: Approximately 73 countries worldwide implemented a daylight saving time (DST) policy: setting their clocks forward in spring and back in fall. The main purpose of this practice is to save electricity. The aim of the present study was to find out how DST affects the incidence and impact of seriously injured patients. (2) Methods: In a retrospective, multi-center study, we used the data recorded in the TraumaRegister DGU® (TR-DGU) between 2003 and 2017 from Germany, Switzerland, and Austria. We compared the included cases 1 week before and after DST. (3) Results: After DST from standard time to summertime, we found an increased incidence of accidents of motorcyclists up to 51.58%. The result is consistent with other studies. (4) Conclusion: However, our results should be interpreted as a tendency. Other influencing factors, such as time of day and weather conditions, were not considered.

Background: Members of the genus Corynebacterium are increasingly recognized as pathobionts and can be very resistant to antimicrobial agents. Previous studies have demonstrated that Corynebacterium striatum can rapidly develop high-level daptomycin resistance (HLDR) (minimum inhibitory concentration [MIC] ≥256 μg/mL). Here we conducted a multi-center study to assay for this in vitro phenotype in diverse Corynebacterium species. Methods: Corynebacterium clinical isolates (n=157) from four medical centers were evaluated. MIC values to daptomycin, vancomycin, and telavancin were determined before and after overnight exposure to daptomycin to identify isolates able to rapidly develop daptomycin non-susceptibility. To investigate assay reproducibility, 18 isolates were evaluated at three study sites. In addition, stability of daptomycin non-susceptibility was tested using repeated subculture without selective pressure. The impact of different media brands was also investigated. Results: Daptomycin non-susceptibility emerged in 12 of 23 species evaluated in this study (C. afermentans, amycolatum, aurimucosum, bovis, jeikeium, macginleyi, pseudodiphtheriticum, resistens, simulans, striatum, tuberculostearicum, and ulcerans) and was detected in 50 of 157 (31.8%) isolates tested. All isolates displayed low (susceptible) MIC values to vancomycin and telavancin before and after daptomycin exposure. Repeated subculture demonstrated 2 of 9 isolates (22.2%) exhibiting HLDR reverted to a susceptible phenotype. Of 30 isolates tested on three media brands, 13 (43.3%) had differences in daptomycin MIC values between brands. Conclusions: Multiple Corynebacterium species can rapidly develop daptomycin non-susceptibility, including HLDR, after a short daptomycin exposure period.

The deportment of each student in a third-grade classroom was rated by the teacher before and after the fall change from Daylight Saving Time (DST), as a test of the hypothesis that change to or from DST has a disruptive effect on behavior. We were surprised to find a significant interaction of sex of student × ratings. Subsequent to the change from DST, the deportment of the boys improved significantly while the deportment of the girls was significantly disrupted.

How is Daylight Saving Time still a thing?: Disruptions from Daylight Saving Time transitions lead to cognitive performance deficits

Visual search, looking for targets among distractors, underlies many critical professions and must often be performed optimally regardless of the time of day, week, or year. However, external events can disrupt the ability to perform. The current study examined one such specific event: Daylight Saving Time (DST) transitions—when the clock shifts forward or backward by one hour. Performance on a visual search task was assessed using “big data” from the mobile app Airport Scanner (Kedlin Co.), wherein players serve as airport security screeners searching for prohibited items among allowed items. Performance was compared between individuals who played a specific level during the week leading up to a DST transition (pre-DST transition) and those who played that same level during the week following a transition (post-DST transition). Analyses of data gathered over seven years revealed that, relative to the pre-DST group, the post- DST group was significantly slower, less likely to complete the level, more likely to fail due to running out of time, and had more false alarms. A control set of data (between individuals who played the level before or after a Sunday without a DST transition) revealed no significant differences. These results suggest that even minor, one-hour time shifts can create problems as they can adversely affect cognitive functioning; when an entire workforce simultaneously undergoes a sudden time shift (e.g., a DST transition), problems can potentially be exacerbated for the broader society. The current study lends support for existing efforts to end the archaic practice of DST.
