CumbraeCraft:a virtual environment for teaching cultural heritage to primary schoolchildren

Game-based learning is a research area that has grown within the past two decades, with evidence of tailoring commercial-off-the-shelf gaming, developing bespoke educational games, and using gamification-based learning tools in a variety of educational settings. However, the Covid-19 pandemic has accelerated the need to focus on virtual learning experiences that are engaging and motivating for schoolchildren to participate in as they face learning from home. Games are one such method of virtual learning experiences that aim to provide a stimulating experience for young people to continue their compulsory education. This paper introduces a project developed between Millport Conservation Area Regeneration Scheme (CARS) and a small team of game development students and academics from Abertay University. The purpose of the project was to develop a Minecraft Education world that could be used by teachers to engage primary schoolchildren in the history and heritage of the Isle of Cumbrae, an island in North Ayrshire, western Scotland. The project also set out to achieve aims of promoting local heritage and heritage tourism, enhancing national educational standards, serving as an electronic record of local heritage, and introducing potential career options in gaming to young people. The result - CumbraeCraft - is a suite of eight lessons that support teachers to use the game within the classroom as a way of teaching young people about local heritage and culture. The world focused on recreating locations and events from the Isle of Cumbrae to present interesting facts and knowledge to pupils in an interactive and enjoyable manner, focusing on interactions of exploration and discovery, narrative and communication, fellowship and teamwork, expression and creativity, and challenge-based learning. The aim of this paper is to present a case study on the design and development of CumbraeCraft as an educational environment to teach the heritage and history of island communities in western Scotland. Additionally, the paper spotlights a gap for games to be used to teach young people about local heritage and the historical significance of their communities and culture, with a particular emphasis on Scottish culture, language, and tradition.</p

Perceptions of Skill Development Among Occupational Therapy Students Who Participated in Virtual Fieldwork: A Qualitative Descriptive Study

Occupational therapy fieldwork helps students refine their professional and technical skills to achieve competency required of entry-level occupational therapists. While fieldwork is traditionally completed in an in-person setting, the COVID-19 pandemic resulted in some students completing fieldwork in a virtual format. Yet, minimal research has explored perceptions of skill development among students who complete virtual fieldwork placements. This qualitative descriptive study examined the perceptions of skill development among graduate-level occupational therapy students and graduates who participated in a virtual fieldwork placement during the COVID-19 pandemic. Eight participants from 3 different states completed semi-structured interviews of no longer than 60 minutes duration via Microsoft Teams. Verbatim interview transcriptions were analyzed by the researchers using a constant-comparative data analysis approach. Four key themes emerged: participants initially experienced uncertainty and had concerns regarding the development of their professional and technical skills; professional and technical skills improved during virtual fieldwork but skill development was perceived to be more difficult to accomplish; communication, peer support, online resources, and utilization of their fieldwork educator were primary strategies for facilitating skills development during virtual fieldwork; and virtual fieldwork provides valuable lessons that are applicable to future practice, but students did not recommend it for other occupational therapy students. The results of this study suggest that while virtual fieldwork placements may be valuable in some situations, educators must carefully consider the benefits and drawbacks before placing students in virtual fieldwork placements in the future and ensure that proper support is provided before and during the placement

Australian University Nursing and Allied Health Students’ and Staff Physical Activity Promotion Preparedness and Knowledge: A Pre-Post Study Using an Educational Intervention

The promotion of physical activity (PA) by health professionals is a key strategy to increase PA levels in the population. In this study, we investigated PA promotion, preparedness, and knowledge among university nursing and allied health students and staff, as well as PA resource usage within curricula, before and after an educational intervention. Students and staff from 13 health disciplines at one Australian university were invited to complete an online survey, and a curriculum audits were conducted before and after PA teaching resources were promoted by academic PA champions (n = 14). A total of 299 students and 43 staff responded to the survey pre-intervention, and 363 and 32 responded to the post-intervention, respectively. PA promotion role perception (≥93%) and confidence to provide general PA advice (≥70%) were high throughout the study. Knowledge of PA guidelines was poor (3–10%). Students of physiotherapy, sport and exercise science, as well as more active students, were more likely to be aware of the PA guidelines (p < 0.05). Over 12 months, PA promotion preparedness and knowledge did not change significantly, nor was there a change in the amount of PA content delivered, despite a significant increase in the use of the teaching resources across a number of disciplines (p = 0.007). Future research should be carried out to investigate the implementation of the resources over time and to develop additional strategies for PA promotion and education scaffolded across curricula

Australasian Malignant PLeural Effusion (AMPLE)-3 trial: Study protocol for a multi-centre randomised study comparing indwelling pleural catheter (±talc pleurodesis) versus video-assisted thoracoscopic surgery for management of malignant pleural effusion

Introduction: Malignant pleural effusions (MPEs) are common. MPE causes significant breathlessness and impairs quality of life. Indwelling pleural catheters (IPC) allow ambulatory drainage and reduce hospital days and re-intervention rates when compared to standard talc slurry pleurodesis. Daily drainage accelerates pleurodesis, and talc instillation via the IPC has been proven feasible and safe. Surgical pleurodesis via video-assisted thoracoscopic surgery (VATS) is considered a one-off intervention for MPE and is often recommended to patients who are fit for surgery. The AMPLE-3 trial is the first randomised trial to compare IPC (±talc pleurodesis) and VATS pleurodesis in those who are fit for surgery. Methods and analysis: A multi-centre, open-labelled randomised trial of patients with symptomatic MPE, expected survival of ≥ 6 months and good performance status randomised 1:1 to either IPC or VATS pleurodesis. Participant randomisation will be minimised for (i) cancer type (mesothelioma vs non-mesothelioma); (ii) previous pleurodesis (vs not); and (iii) trapped lung, if known (vs not). Primary outcome is the need for further ipsilateral pleural interventions over 12 months or until death, if sooner. Secondary outcomes include days in hospital, quality of life (QoL) measures, physical activity levels, safety profile, health economics, adverse events, and survival. The trial will recruit 158 participants who will be followed up for 12 months. Ethics and dissemination: Sir Charles Gairdner and Osborne Park Health Care Group (HREC) has approved the study (reference: RGS356). Results will be published in peer-reviewed journals and presented at scientific meetings. Discussion: Both IPC and VATS are commonly used procedures for MPE. The AMPLE-3 trial will provide data to help define the merits and shortcomings of these procedures and inform future clinical care algorithms.

Modeling Within-Host Dynamics of Influenza Virus Infection Including Immune Responses

Influenza virus infection remains a public health problem worldwide. The mechanisms underlying viral control during an uncomplicated influenza virus infection are not fully understood. Here, we developed a mathematical model including both innate and adaptive immune responses to study the within-host dynamics of equine influenza virus infection in horses. By comparing modeling predictions with both interferon and viral kinetic data, we examined the relative roles of target cell availability, and innate and adaptive immune responses in controlling the virus. Our results show that the rapid and substantial viral decline (about 2 to 4 logs within 1 day) after the peak can be explained by the killing of infected cells mediated by interferon activated cells, such as natural killer cells, during the innate immune response. After the viral load declines to a lower level, the loss of interferon-induced antiviral effect and an increased availability of target cells due to loss of the antiviral state can explain the observed short phase of viral plateau in which the viral level remains unchanged or even experiences a minor second peak in some animals. An adaptive immune response is needed in our model to explain the eventual viral clearance. This study provides a quantitative understanding of the biological factors that can explain the viral and interferon kinetics during a typical influenza virus infection

Enrichment of Omnivorous Cercozoan Nanoflagellates from Coastal Baltic Sea Waters

Free-living nano-sized flagellates are important bacterivores in aquatic habitats. However, some slightly larger forms can also be omnivorous, i.e., forage upon both bacterial and eukaryotic resources. This hitherto largely ignored feeding mode may have pronounced implications for the interpretation of experiments about protistan bacterivory. We followed the response of an uncultured group of omnivorous cercozoan nanoflagellates from the Novel Clade 2 (Cerc_BAL02) to experimental food web manipulation in samples from the Gulf of Gdańsk (Southern Baltic Sea). Seawater was either prefiltered through 5 µm filters to exclude larger predators of nanoflagellates (F-treatment), or prefiltered and subsequently 1∶10 diluted with sterile seawater (F+D-treatment) to stimulate the growth of both, flagellates and bacteria. Initially, Cerc_BAL02 were rapidly enriched under both conditions. They foraged on both, eukaryotic prey and bacteria, and were highly competitive at low concentrations of food. However, these omnivores were later only successful in the F+D treatment, where they eventually represented almost one fifth of all aplastidic nanoflagellates. By contrast, their numbers stagnated in the F-treatment, possibly due to top-down control by a concomitant bloom of other, unidentified flagellates. In analogy with observations about the enrichment of opportunistically growing bacteria in comparable experimental setups we suggest that the low numbers of omnivorous Cerc_Bal02 flagellates in waters of the Gulf of Gdańsk might also be related to their vulnerability to grazing pressure

Population pharmacokinetics of the antimalarial amodiaquine: a pooled analysis to optimize dosing

Amodiaquine plus artesunate is the recommended antimalarial treatment in many countries where malaria is endemic. However, pediatric doses are largely based on a linear extrapolation from adult doses. We pooled data from previously published studies on the pharmacokinetics of amodiaquine, to optimize the dose across all age groups. Adults and children with uncomplicated malaria received daily weight-based doses of amodiaquine or artesunate-amodiaquine over 3 days. Plasma concentration-time profiles for both the parent drug and the metabolite were characterized using nonlinear mixed-effects modeling. Amodiaquine pharmacokinetics were adequately described by a two-compartment disposition model, with first-order elimination leading to the formation of desethylamodiaquine, which was best described by a three-compartment disposition model. Body size and age were the main covariates affecting amodiaquine clearance. After adjusting for the effect of weight, clearance rates for amodiaquine and desethylamodiaquine reached 50% of adult maturation at 2.8 months (95% confidence interval [CI], 1.5 to 3.7 months) and 3.9 months (95% CI, 2.6 to 5.3 months) after birth, assuming that the baby was born at term. Bioavailability was 22.4% (95% CI, 15.6 to 31.9%) lower at the start of treatment than during convalescence, which suggests a malaria disease effect. Neither the drug formulation nor the hemoglobin concentration had an effect on any pharmacokinetic parameters. Results from simulations showed that current manufacturer dosing recommendations resulted in low desethylamodiaquine exposure in patients weighing 8 kg, 15 to 17 kg, 33 to 35 kg, and &gt;62 kg compared to that in a typical 50-kg patient. We propose possible optimized dosing regimens to achieve similar drug exposures among all age groups, which require further validation
