    MSc (Nursing), Faculty of health Sciences, University of the WitwatersrandThis quasi-experimental study assesses the value of simulation based learning for a medical flight crew within an air ambulance service based in Johannesburg, South Africa. The purpose of this study was to assess the value of simulation based learning for air medical crew in performing synchronized cardioversion efficiently, effectively and safely within the air medical environment. The objectives were to determine if there is a difference between the experimental group that had been exposed to a simulation-based learning experience versus a control group that had not, in respect of performing synchronized cardioversion and scene management pertaining to this skill. This was a qausi-experimental study in which stratified random sampling was done to divide the participants into the control and experimental groups using medical qualification as homogenous subsets. The outcome of the study showed that the control group was quicker to first shock than the participants in the experimental group. However, the participants in the experimental group performed the skill more effectively, with regard to doing / following the correct steps in performing the skill of synchronized cardioversion and were safer practitioners. None of the variants within the sample groups had a significant effect on performance of the skill. The conclusion is that within this specific air ambulance service, simulation- based learning improved the performance of synchronized cardioversion in comparison to the normal orientation / training provided in the service

    This thesis reports on a research-through-design (RtD) PhD study. This sought to integrate Design skills and approaches as part of service provision within a healthcare team at Sheffield Childrens Hospital. Working with the chronic pain (CP) team it used a mixed-method approach to understand how design practice could be used to understand context and develop relationships with stakeholders. This supported the development of workshops to explore if demonstrating design skills and approaches to adolescents with CP could have an impact on their management behaviours. Literature suggests there is an increasing demand for design methods outside of the traditional design field. Both by designers, who find themselves working in other disciplines and non-designers, as a route to problem-solving and innovation. In particular, the complexity of health services provision and the call for increased innovation has led to increased use of design methods in healthcare to develop services and as a method to support problem solving in patients. There are complexities when conducting this type of design-led project in healthcare, where there can be conflicting worldviews on evidence and knowledge, and strict ethical procedures to contend with. This thesis follows the journey of the researcher as they navigate this whilst ultimately remaining true to a RtD approach to explore healthcare service provision. The study provides new insights on RtD in healthcare. Interviews and reflective practice suggest that design practice was successful to understand the context, build trust, visualise services, understand service complexity and navigate difficult topics. Self-report data from the workshops found that adolescents enjoyed the sessions and there was some acquisition of ‘designerly’ skills. The study adds to knowledge in the field. It acknowledges the potential value of design to support adolescents but recognises that this has a long way to go with much more work needed. Key findings are: The study argues the value of research through design in healthcare to support healthcare service provision and the future need to articulate this to a healthcare audience. In order to present some of this study approach to healthcare it argues the need of design facilitation to be a recognised design practice. And further unpacking of the specific skills that design professionals can bring to this sector. the recognition of which would encourage design involvement earlier in studies. Finally based on experiences from the study it provides recommendations for other design researchers

    Improving adherence to cardiac rehabilitation programs should reduce the risk of repeat cardiac events and improve quality of life. We present the process of developing and piloting a Facebook support group, Heart Team, which other cardiac health professionals could adapt and trial at their hospital, rehabilitation or community service.Cardiovascular Disease Research Network Project Grant by the Australia Heart Foundatio

    Variant Salmonella Genomic Island 1 Antibiotic Resistance Gene Cluster in Salmonella enterica Serovar Albany

    Salmonella genomic island 1 (SGI1) contains an antibiotic resistance gene cluster and has been previously identified in multidrug-resistant Salmonella enterica serovars Typhimurium DT104, Agona, and Paratyphi B. We identified a variant SGI1 antibiotic-resistance gene cluster in a multidrug-resistant strain of S. enterica serovar Albany isolated from food fish from Thailand and imported to France. In this strain, the streptomycin resistance aadA2 gene cassette in one of the SGI1 integrons was replaced by a dfrA1 gene cassette, conferring resistance to trimethoprim and an open reading frame of unknown function. Thus, this serovar Albany strain represents the fourth S. enterica serovar in which SGI1 has been identified and the first SGI1 example where gene cassette replacement took place in one of its integron structures. The antibiotic resistance gene cluster of serovar Albany strain 7205.00 constitutes a new SGI1 variant; we propose a name of SGI1-F

    Ageing-associated changes in transcriptional elongation influence longevity

    Physiological homeostasis becomes compromised during ageing, as a result of impairment of cellular processes, including transcription and RNA splicing1-4. However, the molecular mechanisms leading to the loss of transcriptional fidelity are so far elusive, as are ways of preventing it. Here we profiled and analysed genome-wide, ageing-related changes in transcriptional processes across different organisms: nematodes, fruitflies, mice, rats and humans. The average transcriptional elongation speed (RNA polymerase II speed) increased with age in all five species. Along with these changes in elongation speed, we observed changes in splicing, including a reduction of unspliced transcripts and the formation of more circular RNAs. Two lifespan-extending interventions, dietary restriction and lowered insulin-IGF signalling, both reversed most of these ageing-related changes. Genetic variants in RNA polymerase II that reduced its speed in worms5 and flies6 increased their lifespan. Similarly, reducing the speed of RNA polymerase II by overexpressing histone components, to counter age-associated changes in nucleosome positioning, also extended lifespan in flies and the division potential of human cells. Our findings uncover fundamental molecular mechanisms underlying animal ageing and lifespan-extending interventions, and point to possible preventive measures

    Airway Epithelial Cell Migration Dynamics: Mmp-9 Role in Cell–Extracellular Matrix Remodeling

    Get PDF
    Cell spreading and migration associated with the expression of the 92-kD gelatinase (matrix metalloproteinase 9 or MMP-9) are important mechanisms involved in the repair of the respiratory epithelium. We investigated the location of MMP-9 and its potential role in migrating human bronchial epithelial cells (HBEC). In vivo and in vitro, MMP-9 accumulated in migrating HBEC located at the leading edge of a wound and MMP-9 expression paralleled cell migration speed. MMP-9 accumulated through an actin-dependent pathway in the advancing lamellipodia of migrating cells and was subsequently found active in the extracellular matrix (ECM). Lamellipodia became anchored through primordial contacts established with type IV collagen. MMP-9 became amassed behind collagen IV where there were fewer cell–ECM contacts. Both collagen IV and MMP-9 were involved in cell migration because when cell–collagen IV interaction was blocked, cells spread slightly but did not migrate; and when MMP-9 activation was prevented, cells remained fixed on primordial contacts and did not advance at all. These observations suggest that MMP-9 controls the migration of repairing HBEC by remodeling the provisional ECM implicated in primordial contacts

    Cardiac Patients’ Experiences and Perceptions of Social Media: Mixed-Methods Study

    Get PDF
    Background: Traditional in-person cardiac rehabilitation has substantial benefits for cardiac patients, which are offset by poor attendance. The rapid increase in social media use in older adults provides an opportunity to reach patients who are eligible for cardiac rehabilitation but unable to attend traditional face-to-face groups. However, there is a paucity of research on cardiac patients’ experiences and perspectives on using social media to support their health.Objective: The aim of this study was to describe cardiac rehabilitation patients’ experiences in using social media in general and their perspective on using social media, particularly Facebook, to support their cardiac health and secondary prevention efforts.Methods: A mixed-methods study was undertaken among cardiac rehabilitation patients in both urban and rural areas. First, this study included a survey (n=284) on social media use and capability. Second, six focus group interviews were conducted with current Facebook users (n=18) to elucidate Facebook experience and perspectives.Results: Social media use was low (28.0%, 79/282) but more common in participants who were under 70 years of age, employed, and had completed high school. Social media users accessed Web-based information on general health issues (65%, 51/79), medications (56%, 44/79), and heart health (43%, 34/79). Participants were motivated to invest time in using Facebook for “keeping in touch” with family and friends and to be informed by expert cardiac health professionals and fellow cardiac participants if given the opportunity. It appeared that participants who had a higher level of Facebook capability (understanding of features and the consequences of their use and efficiency in use) spent more time on Facebook and reported higher levels of “liking,” commenting, or sharing posts. Furthermore, higher Facebook capability appeared to increase a participants’ willingness to participate in a cardiac Facebook support group. More capable users were more receptive to the use of Facebook for cardiac rehabilitation and more likely to express interest in providing peer support. Recommended features for a cardiac rehabilitation Facebook group included a closed group, expert cardiac professional involvement, provision of cardiac health information, and ensuring trustworthiness of the group.Conclusions: Cardiac health professionals have an opportunity to capitalize on cardiac patients’ motivations and social media, mostly Facebook, as well as the capability for supporting cardiac rehabilitation and secondary prevention. Participants’ favored purposeful time spent on Facebook and their cardiac health provides such a purpose for a Facebook intervention. The study results will inform the development of a Facebook intervention for secondary prevention of cardiovascular disease
