    My thesis has a dual focus. It is an account of both the journey of my inquiry, and the outcome of that inquiry. The Professional Doctorate, for which this work is submitted, emphasises practice development and at all times I have kept a watchful eye on my progress towards becoming a 'scholarly professional'. I am a facilitator - this means taking a variety of roles, including group leader, supervisor, coach, mentor, change agent. I use the term 'facilitator' as shorthand for all of these. My thesis makes a contribution to practical knowledge in relation to the subject matter and the methodology. My main focus is the practice of group facilitation, especially the way that a facilitator can work in a distress free manner, when the presence of the facilitator is apparent and distinct through an individual signature. I take the optimistic stance that facilitator presence can be developed, and have gathered a range of ideas that may support the practitioner in this respect, predominantly drawn from my own experiential and theoretical learning. With regard to autoethnography, the issue of judgement criteria is a particular offering. I see the whole of my thesis as autoethnographic, and have navigated a fine line between doing autoethnography, and finding out what an autoethnography is. In fully committing to this methodology, I take on the responsibility of writing from my own experience, whilst incorporating insights from the work of predecessors and peers

    Guidance to inform research recruitment processes for studies involving critically ill patients

    Clinical research in intensive care units (ICUs) is essential for improving treatments for critically ill patients. However, invitations to participate in clinical research in this situation pose numerous challenges. Studies are frequently initiated within a narrow time window when patients are often unconscious and unable to consent. Consultations or consent discussions must therefore be held with consultees or representatives, usually the patient’s relatives. Conversations about research participation in this setting may be difficult, as relatives are often overwhelmed and may feel uneasy about making decisions on behalf of their relatives. In some circumstances, legislation allows doctors to act as consultees or representatives to enrol patients in research. However, there is little good quality evidence on UK stakeholders’ perspectives to inform how recruitment is carried out in ICU studies. The Perspectives Study collected evidence on the views of over 1400 stakeholders, including patients, relatives and healthcare practitioners, many of whom had first-hand experience of ICU treatment and research. This evidence was used to inform good practice guidance on recruitment of critically ill patients to research. Established social science methods and empirical ethics were employed to reflect the interests of stakeholders and justify recommendations. This guidance aims to bridge the gap between the legal frameworks and the realities of ICU studies and to ensure that research recruitment processes reflect the views of patients and families. Researchers and an expert Advisory Group brought different perspectives to interpreting the evidence to develop the guidance. In this article we present guidance for future ICU studies

    Background The immunological escape of tumors represents one of the main ob- stacles to the treatment of malignancies. The blockade of PD-1 or CTLA-4 receptors represented a milestone in the history of immunotherapy. However, immune checkpoint inhibitors seem to be effective in specific cohorts of patients. It has been proposed that their efficacy relies on the presence of an immunological response. Thus, we hypothesized that disruption of the PD-L1/PD-1 axis would synergize with our oncolytic vaccine platform PeptiCRAd. Methods We used murine B16OVA in vivo tumor models and flow cytometry analysis to investigate the immunological background. Results First, we found that high-burden B16OVA tumors were refractory to combination immunotherapy. However, with a more aggressive schedule, tumors with a lower burden were more susceptible to the combination of PeptiCRAd and PD-L1 blockade. The therapy signifi- cantly increased the median survival of mice (Fig. 7). Interestingly, the reduced growth of contralaterally injected B16F10 cells sug- gested the presence of a long lasting immunological memory also against non-targeted antigens. Concerning the functional state of tumor infiltrating lymphocytes (TILs), we found that all the immune therapies would enhance the percentage of activated (PD-1pos TIM- 3neg) T lymphocytes and reduce the amount of exhausted (PD-1pos TIM-3pos) cells compared to placebo. As expected, we found that PeptiCRAd monotherapy could increase the number of antigen spe- cific CD8+ T cells compared to other treatments. However, only the combination with PD-L1 blockade could significantly increase the ra- tio between activated and exhausted pentamer positive cells (p= 0.0058), suggesting that by disrupting the PD-1/PD-L1 axis we could decrease the amount of dysfunctional antigen specific T cells. We ob- served that the anatomical location deeply influenced the state of CD4+ and CD8+ T lymphocytes. In fact, TIM-3 expression was in- creased by 2 fold on TILs compared to splenic and lymphoid T cells. In the CD8+ compartment, the expression of PD-1 on the surface seemed to be restricted to the tumor micro-environment, while CD4 + T cells had a high expression of PD-1 also in lymphoid organs. Interestingly, we found that the levels of PD-1 were significantly higher on CD8+ T cells than on CD4+ T cells into the tumor micro- environment (p < 0.0001). Conclusions In conclusion, we demonstrated that the efficacy of immune check- point inhibitors might be strongly enhanced by their combination with cancer vaccines. PeptiCRAd was able to increase the number of antigen-specific T cells and PD-L1 blockade prevented their exhaus- tion, resulting in long-lasting immunological memory and increased median survival

    Chromatin Reorganization during Myoblast Differentiation Involves the Caspase-Dependent Removal of SATB2

    The induction of lineage-specific gene programs are strongly influenced by alterations in local chromatin architecture. However, key players that impact this genome reorganization remain largely unknown. Here, we report that the removal of the special AT-rich binding protein 2 (SATB2), a nuclear protein known to bind matrix attachment regions, is a key event in initiating myogenic differentiation. The deletion of myoblast SATB2 in vitro initiates chromatin remodeling and accelerates differentiation, which is dependent on the caspase 7-mediated cleavage of SATB2. A genome-wide analysis indicates that SATB2 binding within chromatin loops and near anchor points influences both loop and sub-TAD domain formation. Consequently, the chromatin changes that occur with the removal of SATB2 lead to the derepression of differentiation-inducing factors while also limiting the expression of genes that inhibit this cell fate change. Taken together, this study demonstrates that the temporal control of the SATB2 protein is critical in shaping the chromatin environment and coordinating the myogenic differentiation program

    Behavior of Supramolecular Assemblies of Radiometal-Filled and Fluorescent Carbon Nanocapsules In Vitro and In Vivo

    Hybrid materials based on supramolecularly assembled single-walled carbon nanotubes (SWNTs) are generated for positron emission tomography (PET), magnetic resonance imaging, and fluorescence imaging. The all-in-one imaging probe allows quantitative imaging from subcellular resolution to whole tissue regions. The SWNTs can be exposed to aqueous solutions of non-radioactive and radioactive metal salts in the presence of fullerenes and b-D-glucan. Encapsulating 64Cu ions achieves a minimum of 69% incorporation of radiochemical. The results suggest that this method can be extended to other metal ions of medical relevance, such as zirconium(IV)-89 or rhenium(VII)-188, which are used for medical imaging or radiotherapy, respectively. The in vivo uptake of 64Cu(II)@SWNT@glucan in Wistar rats allows the investigation of organ biodistribution by microPET. Radioactivity rapidly accumulates predominantly in the lungs and myocardium with peak uptakes of 4.8 G 0.9 standardized uptake value. Furthermore, such materials are fully traceable in cells by multiphoton fluorescence lifetime imaging with near-infrared excitation (910 nm)
