The T.E.A.M Approach to Interprofessional Education for Pre-Professional and Professional Health Students

Interprofessional education (IPE) is defined as “students from two or more professions learning about, from and with each other to enable effective collaboration and improve health outcomes” (World Health Organization, 2010). When used effectively, IPE programs aid in preparing pre-professional undergraduate and graduate health professional students to enter the healthcare field as effective team members, who are knowledgeable in delivering quality, collaborative care. This project aimed to 1) assess the impact of current IPE programming, 2) create an evidence-based framework to develop IPE programming and 3) determine if current evaluative processes using the T.E.A.M. reporting tool can adequately reflect the ability for IPE programming to be sustainable. Along with a review of the literature, pre- and post-IPE program surveys were analyzed to create a comprehensive needs assessment using the W.K. Kellogg Foundation Logic Model. From the data compiled, it was determined that initiation of IPE at the foundational level, including exposure of IPE concepts to undergraduate students, would be advantageous. The T.E.A.M. Reporting Tool has the ability to highlight and compare key components to consider prior to implementing IPE events and activities and aligns with the created evidence-based framework to build a sustainable model for IPE.https://engagedscholarship.csuohio.edu/u_poster_2018/1053/thumbnail.jp

Fast-cure ionogel electrolytes with improved ion transport kinetics at room temperature

Fast-cure 1-ethyl-3-methylimidazolium trifluoromethanesulfonate-based ionogels have been realised for the first time. The influence of curing temperature on the structure of ionogels and their performance as the electrolyte for electric double-layer capacitors (EDLCs) has been investigated. Hybrid ionogels were synthesised via a non-hydrolytic sol-gel route and were fully gelled post heat-treating at 125, 150, 175 and 200 °C for 60 min with minimal shrinkage. Charge-transfer resistance (a rate-limiting parameter in cell kinetics during charge/discharge cycles) was reduced by ∼80% by increasing the heat-treatment temperature; this was partially attributed to the interlocking effect facilitated by high curing temperature. We report a maximum areal capacitance of 95 mF cm−2. Due to ∼40% increase in the penetrability coefficient of the ionic liquid, the electrode ‘full’ wetting time dropped from 48 to 5 h when the curing temperature was increased above 150 °C. These results were supported by SEM and Raman spectroscopy to characterise the effect of high temperature heat-treatment on the electrode-ionogel interface and the degree of electrode wetting by the ionic liquid. The fast-cure fabrication process for ionogels removes one of the major hurdles in their industrial application while the improved room temperature ion transport kinetics expands the potential application of ionic liquid-based electrochemical systems

Diagnosis and management of polycystic ovary syndrome in the UK (2004-2014): a retrospective cohort study.

OBJECTIVE: To estimate the incidence and prevalence of polycystic ovary syndrome (PCOS) in UK primary care and investigate prescribing patterns before and after a PCOS diagnosis. DESIGN: Retrospective cohort study. SETTING: UK primary care (2004-2014). PARTICIPANTS: Women aged 15-45 years. PRIMARY AND SECONDARY OUTCOME MEASURES: The incidence and prevalence of diagnosed PCOS and probable PCOS (ie, those without a confirmed diagnosis but with at least 2 PCOS features recorded within 3 years). Among women with diagnosed or probable PCOS, the prevalence of prescribing of drugs typically used to treat PCOS was calculated prior to and in the 24 months after the diagnosis of PCOS. RESULTS: We identified 7233 women with PCOS diagnoses and 7057 women with records suggestive of probable PCOS, corresponding to incidence rates of 0.93 and 0.91 per 1000 person-years at risk (PYAR) and an overall rate of 1.84 per 1000 PYAR. Women aged 20-24 years and women living in deprived areas had the highest incidence of PCOS. The prevalence of PCOS in 2014 was ∼2%. The proportion of women with a prescription in the 24 months after their PCOS index date varied by drug type: 10.2% metformin, 15.2% combined oral contraceptives, 18.8% acne-related treatments, 1.93% clomiphene, 1.0% spironolactone, 0.28% cyproterone and 3.11% eflornithine. Acne-related treatments were more commonly used to treat probable (28.3%) than diagnosed (12.3%) cases, while metformin was prescribed much more commonly in diagnosed cases. CONCLUSIONS: In conclusion, compared to rates estimated in community samples, the incidence and prevalence of women presenting in primary care with PCOS diagnoses and features are low, indicating that PCOS is an under-recognised condition. Although considerable variation is observed in treatments prescribed to women with PCOS, the treatments initiated following a confirmed diagnosis generally reflect the long-term prognostic concerns raised in PCOS consensuses

Hydroxyapatite nanoparticle injectable hydrogel scaffold to support osteogenic differentiation of human mesenchymal stem cells

Bone loss associated with degenerative disease and trauma is a clinical problem increasing with the aging population. Thus, effective bone augmentation strategies are required; however, many have the disadvantages that they require invasive surgery and often the addition of expensive growth factors to induce osteoblast differentiation. Here, we investigated a Laponite crosslinked, pNIPAMDMAc copolymer (L-pNIPAM-co-DMAc) hydrogel with hydroxyapatite nanoparticles (HAPna), which can be maintained as a liquid ex vivo, injected via narrowgauge needle into affected bone, followed by in situ gelation to deliver and induce osteogenic differentiation of human mesenchymal stem cells (hMSC). L-pNIPAMco-DMAc hydrogels were synthesised and HAPna added post polymerisation. Commercial hMSCs from one donor (Lonza) were incorporated in liquid hydrogel, the mixture solidified and cultured for up to 6 weeks. Viability of hMSCs was maintained within hydrogel constructs containing 0.5 mg/mL HAPna. SEM analysis demonstrated matrix deposition in cellular hydrogels which were absent in acellular controls. A significant increase in storage modulus (G’) was observed in cellular hydrogels with 0.5 mg/mL HAPna. Semi-quantitative immunohistochemistry and histological analysis demonstrated that bone differentiation markers and collagen deposition was induced within 48 h, with increased calcium deposition with time. The thermally triggered hydrogel system, described here, was sufficient without the need of additional growth factors or osteogenic media to induce osteogenic differentiation of commercial hMSCs. Preliminary data presented here will be expanded on multiple patient samples to ensure differentiation is seen in these samples. This system could potentially reduce treatment costs and simplify the tre

Mesenchymal stem cell therapies for intervertebral disc degeneration: consideration of the degenerate niche

We have previously reported a synthetic Laponite® crosslinked pNIPAM‐co‐DMAc (NPgel) hydrogel, which induces nucleus pulposus (NP) cell differentiation of human MSCs (hMSCs) without the need for additional growth factors. Furthermore NP gel supports integration following injection into the disc and restores mechanical function to the disc. However, translation of this treatment strategy into clinical application is dependent on the survival and differentiation of hMSC to the correct cell phenotype within the degenerate IVD. Here, we investigated the viability and differentiation of hMSCs within NP gel within a catabolic microenvironment. Human MSCs were encapsulated in NPgel and cultured for 4 weeks under hypoxia (5% O2) with ± calcium, IL‐1β and TNFα either individually or in combination to mimic the degenerate environment. Cell viability, and cellular phenotype was investigated. Stem cell viability was maintained within hydrogel systems for the 4 weeks investigated under all degenerate conditions. NP matrix markers: Agg and Col II and NP phenotypic markers: HIF‐1α, FOXF1 and PAX1 were expressed within the NPgel cultures and expression was not affected by culture within degenerate conditions. Alizarin red staining demonstrated increased calcium deposition under cultures containing CaCl2 indicating calcification of the matrix. Interestingly MMP's, ADAMTS 4 and Col I expression by hMSCs cultured in NPgel was upregulated by calcium but not by pro‐inflammatory cytokines IL‐1β and TNFα. Importantly IL‐1β and TNFα, regarded as key contributors to disc degeneration, were not shown to affect the NP cell differentiation of MSCs in the NPgel. In agreement with our previous findings, NPgel alone was sufficient to induce NP cell differentiation of MSCs, with expression of both aggrecan and collagen type II, under both standard and degenerate culture conditions; thus could provide a therapeutic option for the repair of the NP during IVD degeneration

Generative mechanisms for innovation in information infrastructures

This paper investigates how innovation of ICT based services takes place within existing infrastructures, including the whole network of technology, vendors and customers. Our research question is, how can an information infrastructure provide generative mechanisms for innovation of ICT based services? Building on a critical realist approach, our empirical evidence was a case study within an international airline, aiming to diversify its services. From our analysis we propose that there are two self-reinforcement mechanisms in information infrastructures. First, we identified the innovation reinforcement mechanism, resulting in new services. Second, there is the service reinforcement mechanism, resulting in more users and profits. The practical implication of our framework is to show that although ICT-based innovation cannot be planned and managed in detail, the innovation mechanism may help organisations to facilitate the innovation process in a structured way

Emergence of skew distributions in controlled growth processes

Starting from a master equation, we derive the evolution equation for the size distribution of elements in an evolving system, where each element can grow, divide into two, and produce new elements. We then probe general solutions of the evolution quation, to obtain such skew distributions as power-law, log-normal, and Weibull distributions, depending on the growth or division and production. Specifically, repeated production of elements of uniform size leads to power-law distributions, whereas production of elements with the size distributed according to the current distribution as well as no production of new elements results in log-normal distributions. Finally, division into two, or binary fission, bears Weibull distributions. Numerical simulations are also carried out, confirming the validity of the obtained solutions.Comment: 9 pages, 3 figure

Molecular basis for maize as a risk factor for oesophageal cancer in a South African population

Throughout the world squamous cell carcinoma of the oesophagus seems to be an increasing problem. There is a huge variation in prevalence globally; locations such as Japan, Iran, China and Finland can have ten times the prevalence compared to other western countries. One place that is hugely affected is Transkei, a 16,000 square mile area of South Africa. Some of the factors proposed to be implicated with squamous cell carcinoma in this region include tobacco smoking, alcohol consumption, bacterial infections and fungal infection of common food crops. In addition, the ‘Sammon theory’ links carcinogenesis in Transkei to the high consumption of maize by the population. Through a chain of reactions it is postulated that a component of maize inhibits the breakdown of growth factors, which have already been implicated in cancer. This study investigates the Transkei population and updates the Sammon theory with current research to predict a theory at a molecular level. This theory is then tested with novel research to show PGE2, shown here in high concentrations in gastric fluid samples, directly increases the proliferation of oesophageal cell lines. Gastric fluid samples from the Transkei population are then shown to have a mitogenic effect on oesophageal cells, supporting a theory that gastric fluid regurgitation commonly found in this population predisposes them to cancer. Further experimentation on the expression of related proteins shows how high PGE2 may increase its own production by increasing COX 2 expression, leading to a positive feedback loop causing constant proliferative stimulation of the oesophageal squamous tissue in the presence of the COX 2 substrate, aracadonic acid. Therefore this thesis suggests that a high maize diet provides the correct conditions for regurgitation of increased concentrations of PGE2 into the oesophagus leading to squamous hyper-proliferation over long periods of time through self stimulated production, which would normally have ceased over a much shorter time if only localised PGE2 was produced through natural restitution.EThOS - Electronic Theses Online ServiceGBUnited Kingdo
