AbstractVisual feedback gait retraining has been reported to successfully reduce impact loading in runners, even when the runners were distracted. However, auditory feedback is more feasible in real life application. Hence, this study compared the peak positive acceleration (PPA), vertical average (VALR) and instantaneous (VILR) loading rate during distracted running before and after a course of auditory feedback gait retraining in 16 runners. The runners were asked to land with softer footfalls with and without auditory feedback. Low or high sound pitch was generated according to the impact of particular footfall, when compared with the preset target. Runners then received a course of auditory gait retraining, and after the gait retraining, runners completed a reassessment. Runners before gait retraining exhibited lower PPA, VALR and VILR with augmented auditory feedback (p<0.049). We found a reduction in PPA, VALR and VILR after gait retraining, regardless of the presence of feedback (p<0.018). However, runners after gait retraining did not demonstrate further reduction in PPA and VALR with auditory feedback (p>0.104). A small effect of auditory feedback on VILR in runners after gait retraining was observed (p=0.032). Real time auditory feedback gait retraining is effective in impact loading reduction, even when the runners were distracted.

The Impact

The deployment of measures to mitigate sound during propagation outdoors is most often a compromise between the acoustic design, practical limitations, and visual preferences regarding the landscape. The current study of a raised berm next to a highway shows a number of common issues like the impact of the limited length of the noise shielding device, initially non-dominant sounds becoming noticeable, local drops in efficiency when the barrier is not fully continuous, and overall limited abatement efficiencies. Detailed assessments of both the objective and subjective effect of the intervention, both before and after the intervention was deployed, using the same methodology, showed that especially the more noise sensitive persons benefit from the noise abatement. Reducing the highest exposure levels did not result anymore in a different perception compared to more noise insensitive persons. People do react to spatial variation in exposure and abatement efficiency. Although level reductions might not be excessive in many real-life complex multi-source situations, they do improve the perception of the acoustic environment in the public space.

We investigated the impact of nutrient intake on hydration biomarkers in cyclists before and after a 161 km ride, including one hour after a 650 mL water bolus consumed post-ride. To control for multicollinearity, we chose a clustering-based, machine learning statistical approach. Five hydration biomarkers (urine color, urine specific gravity, plasma osmolality, plasma copeptin, and body mass change) were configured as raw- and percent change. Linear regressions were used to test for associations between hydration markers and eight predictor terms derived from 19 nutrients merged into a reduced-dimensionality dataset through serial k-means clustering. Most predictor groups showed significant association with at least one hydration biomarker: (1) Glycemic Load + Carbohydrates + Sodium, (2) Protein + Fat + Zinc, (3) Magnesium + Calcium, (4) Pinitol, (5) Caffeine, (6) Fiber + Betaine, and (7) Water; potassium + three polyols, and mannitol + sorbitol showed no significant associations with any hydration biomarker. All five hydration biomarkers were associated with at least one nutrient predictor in at least one configuration. We conclude that in a real-life scenario, some nutrients may serve as mediators of body water, and urine-specific hydration biomarkers may be more responsive to nutrient intake than measures derived from plasma or body mass.

Abstract Background: Healthcare workers (HCWs) not adhering to physical distancing recommendations is a risk factor for acquisition of severe acute respiratory coronavirus virus 2 (SARS-CoV-2). The study objective was to assess the impact of interventions to improve HCW physical distancing on actual distance between HCWs in a real-life setting. Methods: HCWs voluntarily wore proximity beacons to measure the number and intensity of physical distancing interactions between each other in a pediatric intensive care unit. We compared interactions before and after implementing a bundle of interventions including changes to the layout of workstations, cognitive aids, and individual feedback from wearable proximity beacons. Results: Overall, we recorded 10,788 interactions within 6 feet (∼2 m) and lasting >5 seconds. The number of HCWs wearing beacons fluctuated daily and increased over the study period. On average, 13 beacons were worn daily (32% of possible staff; range, 2–32 per day). We recorded 3,218 interactions before the interventions and 7,570 interactions after the interventions began. Using regression analysis accounting for the maximum number of potential interactions if all staff had worn beacons on a given day, there was a 1% decline in the number of interactions per possible interactions in the postintervention period (incident rate ratio, 0.99; 95% confidence interval, 0.98–1.00; P = .02) with fewer interactions occurring at nursing stations, in workrooms and during morning rounds. Conclusions: Using quantitative data from wearable proximity beacons, we found an overall small decline in interactions within 6 feet between HCWs in a busy intensive care unit after a multifaceted bundle of interventions was implemented to improve physical distancing.

Abstract Background and Aims Managing hyperkalemia with a strict diet is limiting and difficult for patients. We sought to measure the impact of online education for patients/caregivers on knowledge and confidence as well as prompting change in daily life. Method The patient/caregiver education was designed as 2 online, interactive activities. Both were comprised of text and integrated visuals; the second also included a patient commentary video. Demographic questions were asked prior to starting the education. A knowledge question was asked both before and after the activity to assess learning gains, as well as intent to change and confidence questions at the end. Absolute improvements were calculated for pre/post questions. The activities launched in April and May of 2019, and data collected through October 2019. Results To date, 98,462 learners have participated in the patient/caregiver activity. Activity 1: High Potassium: Causes and reasons to Treat Participants: 60,060 Completers of all questions (included in outcomes analysis): 7,262 Demographics: 59% female; 49% white, non-Hispanic; 66% over the age of 54; 16% have hyperkalemia, 75% were interested in learning more about the condition Knowledge changes: 13% improvement in understanding what causes hyperkalemia (46% pre to 59% post) Intent-to-act: 66% plan to talk to an HCP about next steps for treating hyperkalemia Confidence changes: 82% reported increased confidence understanding why it’s important to treat hyperkalemia Activity 2: It’s Complicated: How to Manage High Potassium and Heart Failure Participants: 38,402 Completers of all questions (included in outcomes analysis): 3,816 Demographics: 60% female; 63% white, non-Hispanic; 69% over the age of 54; 58% were interested in learning more about the condition and 25% have this condition Knowledge changes: 13% improvement in recognizing how potassium levels effect the heart (76% pre to 89% post) Intent-to-act: 64% plan to talk to their healthcare provider about a plan to manage my hyperkalemia Confidence changes: 82% reported increased confidence understanding how important is it to manage my heart failure and hyperkalemia Conclusion The metrics and outcomes gathered in this assessment are a strong indicator that these patient/caregiver-focused online educational activities improved knowledge and confidence, and prompted intent to act by patients/caregivers related to hyperkalemia.

The Impact

The impact loading of a notched semi-circular bend (NSCB) specimen of outcrop shale in Changning Sichuan was carried out using a split Hopkinson pressure bar (SHPB) to study the effect of shale bedding on the dynamic crack initiation toughness. Three loading configurations were tested: Crack-divider, Crack-splitter and Crack-arrester loading. Bedding plane has a significant effect on the crack initiation of shale. Under the Crack-divider and Crack-splitter modes, shale had lower dynamic crack initiation toughness. The dynamic crack initiation toughness of the shale was affected by the loading rate for all three loading configurations. The correlation between loading rate and dynamic crack initiation toughness was most significant for the Crack-arrester mode, while the Crack-splitter mode was the weakest. When loading was carried out on Crack-arrester, the bedding plane could change the direction of crack growth. In the Crack-splitter mode, only a small impact energy was needed to achieve effective expansion of a crack. The research results provide a theoretical basis for shale cracking.

The Impact

Fasting during the month of Ramadan consists of alternate abstinence and re-feeding periods (circadian or intermittent fasting). Nothing is currently known on the impact of this kind of fasting on psoriasis. A sample of 108 moderate-to-severe plaque psoriasis patients (aged 42.84 ± 13.61 years, 62 males, 46 females) volunteered to take part in the study. A significant change in the “Psoriasis Area and Severity Index” (PASI) score before and after the Ramadan fasting (mean difference = −0.89 ± 1.21, p < 0.0001) was found. At the multivariate regression, the use of apremilast (p = 0.0009), cyclosporine (p = 0.0003), phototherapy (p = 0.0015), interleukin-17 or IL-17 blockers (p < 0.0001), and tumor necrosis factor or TNF blockers (p = 0.0107) predicted the PASI score before the Ramadan fasting. Disease duration (p = 0.0078), use of apremilast (p = 0.0005), and of mammalian target of rapamycin or mTOR inhibitors (p = 0.0034) resulted in independent predictors of the change in the PASI score before and after the Ramadan fasting. The consumption of cyclosporine (p < 0.0001), phototherapy (p = 0.0015), IL-17 blockers (p < 0.0001), mTOR inhibitors (p = 0.0081), and TNF blockers (p = 0.0017) predicted the PASI score after the Ramadan fasting. These findings reflect the influence of dieting strategy, the biological clock, and circadian rhythm on the treatment of plaque psoriasis.

Abstract. Background: Health-care professionals do not routinely receive training on how best to support parents bereaved by suicide. Evidence-based training – Postvention Assisting Those Bereaved by Suicide (PABBS) – was designed to address this gap. Aims: The study aimed (a) to pilot PABBS training and evaluate its perceived effectiveness (impact on self-reported knowledge, skills and confidence) in managing suicide bereavement; and (b) to explore training acceptability. Method: A pre- and postevaluation design was used. Professionals attended intensive, structured 1-day PABBS training comprising: didactic/interactive teaching; practice-orientated activities supported with real-life materials and a manual/workbook. Evaluation forms completed immediately before and after training analyzed: (a) self-reported changes in knowledge, skills, and confidence (perceived effectiveness of training); and (b) the acceptability of training. Results: In total, 62 professionals completed training. Perceived knowledge, skills, and confidence improved after training as did self-reported understanding, motivation to learn more, and intention to change practice. Training was highly rated, particularly the evidence-based, real-life materials, with some suggestions for improvement. Limitations: Self-selected sample and reliance on self-report measures are the study's limitations. Conclusion: PABBS training may help address gaps in professionals' capacity to support parents bereaved by suicide. The evidence-based content was highly acceptable and appeared to be a key ingredient in effecting self-reported changes in attitudes/intentions.

This paper aims to present and evaluate the performance of one of the first real-time bus dispatching system in Bangkok, Thailand. The proposed bus dispatching system receives the real-time bus location data from the RFID sensor network. The paper provides the background and brief description of both the hardware and architecture of the RFID sensornetwork and the real-time bus dispatching system. The bus dispatching system continuously monitors the status of each bus and updates its expected arrival time at the depot using the real-time data from the RFID sensor network. If the expected number of vehicles falls below the required level, then the bus dispatching system will adjust the service headwayand vehicle/driver assignments to minimize the impact on the service headway. The system is implemented on one of a bus lines in Bangkok. The main focus of the paper is to evaluate the performance of the implemented system by comparing the bus service qualities before and after the implementation of the real-time bus dispatching system. One month bus service data both before and after the system deployment are used in the evaluation of the bus level of service. The result illustrates the potential real-life benefit of the real-time bus dispatching system despite the simplicity of the timetable adjustment strategy.
