OBJECTIVES: Expiratory muscle strength training (EMST) is a threshold based device-driven treatment for improving expiratory pressure. EMST proved to be effective in different patient groups to improve cough function. To date, EMST has not been tested in the total laryngectomy population (TL).METHODS: This prospective, randomized case-series study examined feasibility, safety, and compliance of EMST in a group of TL participants and its effects on pulmonary function, physical exertion, fatigue, and vocal functioning. Ten TL participants were included in the study to perform a 4 till 8 weeks of EMST. Objective and subjective outcome measures included manometry, spirometry, cardio pulmonary exercise testing (CPET), voice recordings, and patient reported outcome measures. Group means were reported and estimates of the effect are shown with a 95% confidence interval, using single sample t-tests.RESULTS: Nine participants completed the full study protocol. Compliance to the training program was high. All were able to perform the training, although it requires adjustments of the device and skills of the participants. Maximum expiratory pressure (MEP) and vocal functioning in loudness improved over time. After EMST no changes were seen in other objective and subjective outcomes.CONCLUSIONS: EMST appears to be feasible and safe after total laryngectomy. MEP improved over time but no improvement in the clinically relevant outcome measures were seen in this sample of relatively fit participants. Further investigation of the training in a larger group of participants who report specifically pulmonary complaints is recommended to investigate if the increase in MEP results in clinical benefits.LEVEL OF EVIDENCE: 4.
BackgroundOcclusions of intravenous (IV) tubing can prevent vital and time-critical medication or solutions from being delivered into the bloodstream of patients receiving IV therapy. At low flow rates (≤ 1 ml/h) the alarm delay (time to an alert to the user) can be up to 2 h using conventional pressure threshold algorithms. In order to reduce alarm delays we developed and evaluated the performance of two new real-time occlusion detection algorithms and one co-occlusion detector that determines the correlation in trends in pressure changes for multiple pumps.MethodsBench-tested experimental runs were recorded in triplicate at rates of 1, 2, 4, 8, 16, and 32 ml/h. Each run consisted of 10 min of non-occluded infusion followed by a period of occluded infusion of 10 min or until a conventional occlusion alarm at 400 mmHg occurred. The first algorithm based on binary logistic regression attempts to detect occlusions based on the pump’s administration rate Q(t) and pressure sensor readings P(t). The second algorithm continuously monitored whether the actual variation in the pressure exceeded a threshold of 2 standard deviations (SD) above the baseline pressure. When a pump detected an occlusion using the SD algorithm, a third algorithm correlated the pressures of multiple pumps to detect the presence of a shared occlusion. The algorithms were evaluated using 6 bench-tested baseline single-pump occlusion scenarios, 9 single-pump validation scenarios and 7 multi-pump co-occlusion scenarios (i.e. with flow rates of 1 + 1, 1 + 2, 1 + 4, 1 + 8, 1 + 16, and 1 + 32 ml/h respectively). Alarm delay was the primary performance measure.ResultsIn the baseline single-pump occlusion scenarios, the overall mean ± SD alarm delay of the regression and SD algorithms were 1.8 ± 0.8 min and 0.4 ± 0.2 min, respectively. Compared to the delay of the conventional alarm this corresponds to a mean time reduction of 76% (P = 0.003) and 95% (P = 0.001), respectively. In the validation scenarios the overall mean ± SD alarm delay of the regression and SD algorithms were respectively 1.8 ± 1.6 min and 0.3 ± 0.2 min, corresponding to a mean time reduction of 77% and 95%. In the multi-pump scenarios a correlation > 0.8 between multiple pump pressures after initial occlusion detection by the SD algorithm had a mean ± SD alarm delay of 0.4 ± 0.2 min. In 2 out of the 9 validation scenarios an occlusion was not detected by the regression algorithm before a conventional occlusion alarm occurred. Otherwise no occlusions were missed.ConclusionsIn single pumps, both the regression and SD algorithm considerably reduced alarm delay compared to conventional pressure limit-based detection. The SD algorithm appeared to be more robust than the regression algorithm. For multiple pumps the correlation algorithm reliably detected co-occlusions. The latter may be used to localize the segment of tubing in which the occlusion occurs.

Purpose - Focusing on management training, this study aimed to establish whether identical elements in a training program (i.e. aspects resembling participants' work situation) can improve training transfer and whether they do so beyond the contribution of two well-established predictors -- motivation to learn and expected utility. In an effort to establish mechanisms connecting identical elements with training transfer, we proposed and tested motivation to transfer as a mediator. Design/methodology/approach - Data were collected online from 595 general managers who participated in a management training program. Structural equations modeling was used to test the model. Findings - Identical elements, expected utility and motivation to learn each had a unique contribution to the prediction of training transfer. Whereas motivation to learn partly mediated these relationships, identical elements and expected utility also showed direct associations with training transfer. Research limitations/implications - Identical elements represent a relevant predictor of training transfer. In future research, a longitudinal analysis from different perspectives would be useful to better understand the process of training transfer. Practical implications - Participants may profit more from management training programs when the training better resembles participants' work situation. Organisations and trainers should therefore apply the concept of identical elements in their trainings, in order to increase its value and impact. Originality/value - This study contributes to the training literature by showing the relevance of identical elements for transfer, over and above established predictors.
The pressure on the European health care system is increasing considerably: more elderly people and patients with chronic diseases in need of (rehabilitation) care, a diminishing work force and health care costs continuing to rise. Several measures to counteract this are proposed, such as reduction of the length of stay in hospitals or rehabilitation centres by improving interprofessional and person-centred collaboration between health and social care professionals. Although there is a lot of attention for interprofessional education and collaborative practice (IPECP), the consortium senses a gap between competence levels of future professionals and the levels needed in rehabilitation practice. Therefore, the transfer from tertiary education to practice concerning IPECP in rehabilitation is the central theme of the project. Regional bonds between higher education institutions and rehabilitation centres will be strengthened in order to align IPECP. On the one hand we deliver a set of basic and advanced modules on functioning according to the WHO’s International Classification of Functioning, Disability and Health and a set of (assessment) tools on interprofessional skills training. Also, applications of this theory in promising approaches, both in education and in rehabilitation practice, are regionally being piloted and adapted for use in other regions. Field visits by professionals from practice to exchange experiences is included in this work package. We aim to deliver a range of learning materials, from modules on theory to guidelines on how to set up and run a student-run interprofessional learning ward in a rehabilitation centre. All tested outputs will be published on the INPRO-website and made available to be implemented in the core curricula in tertiary education and for lifelong learning in health care practice. This will ultimately contribute to improve functioning and health outcomes and quality of life of patients in rehabilitation centres and beyond.
This project addresses the critical issue of staff shortages and training inefficiencies in the hospitality industry, particularly focusing on the hotel sector. It connects with the urgent need for innovative, and effective training solutions to equip (inexperienced) staff with hospitality skills, thereby improving service quality and sustainable career prospects in the hotel industry. The project develops and tests immersive technologies (augmented and virtual reality, AR/VR) tailored to meet specific training needs of hotels. Traditional training methods such as personal trainings, seminars, and written manuals are proving inadequate in terms of learning effectiveness and job readiness, leading to high working pressure and poor staff well-being. This project aims to break this cycle by co-creating immersive training methods that promise to be more engaging and effective. Hotelschool The Hague has initiated steps in this direction by exploring AR and VR technologies for hotel staff training. This project builds on these efforts, aiming to develop accessible, immersive training tools specifically designed for the hotel sector. Specifically, this project aims to explore the effectiveness of these immersive trainings, an aspect largely overlooked in the rapid development of immersive technology solutions. The central research question is: How do immersive AR and VR training methods impact job readiness and learning effectiveness in the hotel sector? The one-year KIEM project period involves co-creating, implementing, and evaluating immersive training in collaboration with Hotelschool The Hague and Hyatt Andaz Amsterdam Prinsengracht Hotel in real-life settings. The partnership with Warp Industries, a leader in immersive technology, is crucial for the project’s success. Our findings will be co-created and multiplied through relevant sector associations such as House of Hospitality. This project aligns with the MV’s Impact Level 1: Transitions by promoting innovative training strategies that can lead to a fundamental shift in the hospitality industry, thereby enhancing social earning capacities.
Een substantiële groep jongeren en jongvolwassenen ondervindt ernstige problemen vanwege hun licht verstandelijke beperking (LVB). Naast een laag IQ en beperkt aanpassingsvermogen betekent het hebben van een LVB vaak ook dat er op andere leefgebieden beperkingen zijn. Beperkte impulscontrole is een centraal kenmerk van LVB, en vandaaruit – in combinatie met andere factoren – ontwikkelen zich problemen zoals verslaving of agressief gedrag. Dit heeft gevolgen voor de veiligheid van cliënten en medewerkers in de residentiele (jeugd)zorg en het heeft daarnaast een negatief effect op de behandeling en participatie in de maatschappij. Met name de gevoeligheid van deze jongeren en jongvolwassenen voor sociale druk (peer pressure) draagt bij aan deze problematiek. Beschikbare trainingen en therapieën gericht op het vergroten van sociale weerbaarheid tegen peer pressure sluiten vaak onvoldoende aan op de beleving, motivatie, leermethoden en informatieverwerking van jongeren en jongvolwassenen met een LVB en hebben daardoor niet altijd het gewenste resultaat. Daarnaast laat de generalisatie van het geleerde naar het dagelijks leven vaak te wensen over. De residentiële jeugdzorg ziet de samenwerking met de creatieve industrie als noodzakelijk om innovatieve therapeutische interventies te ontwikkelen die beter aansluiten op de beperkingen van deze doelgroep. Dit project zet daarvoor een eerste stap om Virtual Reality (VR) in te zetten om weerbaarheid tegen peer pressure bij jongeren/jongvolwassenen te verbeteren en uiteindelijk een effectieve behandelmethode te ontwikkelen. Doel van het project is tweeledig: enerzijds een participatief ontwerptraject voor een VR-film die ingezet kan worden binnen de bestaande behandeling, gebaseerd op wensen, ervaringen en input van de doelgroep; ook een kleinschalige evaluatie van de haalbaarheid van de VR-film als therapeutisch interventiemiddel maakt deel uit van dit project. De VR-film en de pilot dienen als onderbouwing voor de aanvraag van verdere onderzoeksgelden. Anderzijds dient dit project als verkenning van de mogelijkheden voor samenwerking in ontwerpend onderzoek in een nieuw netwerk, waarvan de kern bestaat uit de Hogeschool Utrecht, Pluryn / Intermetzo, en ontwerpbureau Coolminds.
