Purpose Recently, there has been increased emphasis in the dysphagia literature on what constitutes the “normal” swallow, including rates of aspiration and penetration in healthy persons across the age ranges. Since a majority of the normed-based studies utilized videofluoroscopy and were conducted in a tightly controlled environment, there is a need to increase the ecological validity of this body of research and investigate the swallow during functional, day-to-day activities. The aim of this study is to track the incidence of swallowing difficulty in young, healthy adults over an extended period to determine the frequency of aspiration-related events and under what environmental circumstances these events occurred. Method Sixty-nine young, healthy women (aged 18–39 years) participated in the study and recorded data for 95 consecutive days. Participants installed a web-based application on their cell phones and were asked to access the app and answer three simple questions immediately following any adverse swallowing events. These data were used to determine the frequency of aspiration-related events and their relationship to environmental circumstance. Results Fifty-three of the 69 participants (76.8%) reported coughing or choking, 43 (62.3%) reported clearing their throat, 19 (27.5%) reported a globus sensation, and 14 (20.2%) reported difficulty initiating a swallow. The environmental circumstances most commonly associated with aspiration-related events were talking, being distracted, and using an electronic device. Conclusion Results suggest that young, healthy adults experience aspiration-related events at a high frequency and that these events typically occur during activities that require dual attention.

The purpose of this study was to examine the relationships among active transport, electronic device-use, and self-reported school week moderate-to-vigorous physical activity (MVPA) in a sample of adolescents. The sample consisted of 1445 adolescents enrolled in the Family Life, Activity, Sun, Health, and Eating study. A panel research organization invited panel members balanced to the US population on sex, census division, household income and size, and race/ethnicity. Web-based surveys were administered to each selected adolescent. Adolescents answered questions pertaining to out-of-school electronic device-use and active transport to and from school. Predicted weekly minutes of MVPA were calculated from the Youth Activity Profile. The outcome variable was predicted school week MVPA (in minutes). The predictive utility of device-use and active transport variables on self-reported school week MVPA were examined using weighted multiple linear regression models. After adjusting for age, sex, and BMI, active transport to school (b = 12.32, 95% CI [9.72–14.93], p < 0.001) and from school (b = 7.18, 95% CI [4.79–5.57], p < 0.001) were significantly associated with self-reported school week MVPA. No device-use variables were significantly associated with school week MVPA. Active transport to and from school may have an impact on school week MVPA in adolescents.

AbstractTo perform a task continuously over an extended period of time, it is necessary to maintain an adequate level of arousal. In cognitive research, traditional studies have used repetitive, monotonous tasks to learn about the dynamics of arousal in tasks that require sustained vigilance, such as driving or monitoring a factory line. To date, studies have rarely considered whether observers use task-embedded regularities in such continuous contexts to anticipate events and regulate arousal accordingly. In the current study, we explored whether arousal is an adaptive process that reacts to temporal stimulus predictability. Across two experiments, we used pupillometry as a proxy measure of arousal in human observers performing continuous tasks. Within the tasks, we manipulated the temporal predictability of relevant events by presenting stimuli either in a fixed rhythm or at varied intervals. Temporal predictability led to the lowering of tonic levels of arousal. Trial-wise temporal structures led to short-scale changes in pupil size related to temporal anticipation. Accordingly, we suggest that arousal is sensitive to varying levels of temporal predictability and dynamically adapts to task demands to bring about performance benefits as well as energetic efficiencies overall.Statement of RelevancePeople often have to sustain focus and high levels of performance on extended and non-stimulating tasks (e.g., driving, sowing, monitoring data acquisition). A critical factor to the success (or failure) in sustained performance is arousal – the ‘energetic state’ of the cognitive system. Here we used pupil dilation as a proxy to study levels of arousal during sustained performance on monotonous tasks. We reveal that arousal is dynamically regulated to support performance according to an important fundamental property of any task: its temporal structure. When the timing of task-relevant events is predictable, arousal levels fluctuate accordingly, saving energy overall while also optimally guiding performance. Our study and findings add ecological validity to the study of temporal expectations, by moving investigations beyond typical trial-by-trial designs. They also carry significant implications for clinical studies relying on sustained performance tasks.

The effect of water deficit on floral initiation, leaf development and yield of commercial leaf of tobacco planted in the winter was studied in northern Queensland. The deficits were induced by different watering treatments at transplanting in combination with a range of times during which irrigation was withheld after transplanting. In addition, the effect of two periods of water deficits on flower and leaf development was investigated in a pot experiment under controlled environment conditions. Water deficits after transplanting delayed floral initiation and allowed more leaves to be produced. Moreover, the size of most leaves of commercial value was increased by water deficit; for example, withholding water for 28 days after transplanting increased the area and dry weight of commercial yield per plant by 33%. Results from the pot experiment demonstrated that the larger leaf area resulted from an extended period of linear growth and a greater rate of expansion after water deficits were relieved.

The Impact

IntroductionThe pulmonary passport (PP) is a secure web-based procedural logbook for specialist respiratory trainees with enhanced functionality that includes automated analysis to provide key performance metrics and in-platform interactions with supervisors.MethodsThis service evaluation study used preimplementation and postimplementation online surveys in both trainees and supervisors along with analysis of recorded data within the PP to evaluate the impact of this service on data capture, training, appraisal and quality assurance.ResultsFrom August 2017 to August 2019, 69/73 (95%) specialist respiratory trainees eligible to use the PP across two UK health education deaneries registered with the system and logged 7352 procedures. 3105 thoracic ultrasound procedures identified 2145 pleural effusions and resulted in 1253 pleural procedures of which 96% were successful. 4% of ultrasounds required referral to a more expert sonographer. Iatrogenic bleeding and pneumothorax both occurred in ≤1% of all pleural procedures. 1909 basic diagnostic bronchoscopies were recorded including 1236 bronchial washes, 328 brushes and 221 endobronchial biopsies where definite tumour was identified (biopsy sensitivity 74%). Preimplementation and postimplementation survey data confirmed the PP had increased the consistency of logging procedures by trainees, the depth of data captured, the review of procedural performance metrics in appraisal and the frequency of formal supervisor feedback.DiscussionIn this regional project, the implementation of a web-based procedural logbook has been feasible with excellent uptake and has enhanced procedural recording, supervision and appraisal. Furthermore, it provides unprecedented quality assurance at an individual trainee, trust and deanery level and has a number of potential wider applications in the future.

AbstractEffective data management is a major challenge for neuroscience labs, and even greater for collaborative projects. In the International Brain laboratory (IBL), ten experimental labs spanning 7 geographically distributed sites measure neural activity across the brains of mice making perceptual decisions. Here, we report a novel, modular architecture that allows users to contribute, access, and analyze data across this collaboration. Users contribute data using a web-based electronic lab notebook (Alyx), which automatically registers recorded data files and uploads them to a central server. Users access data with a lightweight interface, the Open Neurophysiology Environment (ONE), which searches data from all labs and loads it into MATLAB or Python. To analyze data, we have developed pipelines based on DataJoint, which automatically populate a website displaying a graphical summary of results to date. This architecture provides a new framework to contribute, access and analyze data, surmounting many challenges currently faced by neuroscientists.

The greenhouse which is a building used to manipulate the micro-climate is an essential building for plant growth. Greenhouses have one or more devices that are used to monitor their internal environments against changes in micro-climate. The problem is that some devices are metal-based devices and plastics that can be deformed, such as electronic devices, one of which is a micro-climate monitoring device, so a shield that can protect the device but does not interfere with the sensor readings is needed. The purpose of this study was to make and test a plastic-based container called Duradus Junction Box, which has six removable ventilation openings to measure the micro-climate data. This study uses five Duradus Junction Boxes with different numbers of ventilation openings, a micro-controller connected to the air temperature and relative humidity sensor, and a MicroSD module to record all micro-climate data, all devices being then tested simultaneously for 30 days. Statistically, after using One Way ANOVA, this study found that micro-climate measurements result for actual devices data can be considered similar because the P-value for temperature (0.886) and relative humidity (0.917) is greater than alpha level of 0.05. However, when reading the recorded data for both parameters, it can be seen that micro-climate data inside all shields are slightly higher than actual microclimate data ranging from 1 to 2oC for air temperature and 1 to 3% for air relative humidity.
