An Examination of the Chance Elements in Witold Lutosławski's Music, with Particular Attention to Its Function as a Model for Compositional Practice

This thesis studies the use of aleatory techniques in Witold Lutosławski's music and the issues that arise when using aleatoricism, a branch of textural composition that has room for exploration. I focused my study on three of Lutosławski's major works, analysing his approach to aleatoricism, form, and macro- and micro-rhythm. I wrote three works for the portfolio component. My approach to aleatoricism differed in each work. Through studying Lutosławski and my own composition, I came across practical issues in creating the score, issues with performers, and compositional problems. However, once these issues were worked though, aleatoricism is a exciting compositional device that is not yet tired

Long-term topical corticosteroid use and risk of skin cancer: a systematic review protocol

Review question/objective: The objective of this systematic review is to synthesize the best available research evidence to determine the risk of skin cancer in patients on long-term use of topical corticosteroids. Specifically the review question is: In people using long-term (regular use over one month) topical corticosteroids, what is the risk of developing skin cancer (clinically or histologically confirmed basal cell carcinoma, squamous cell carcinoma or melanoma)

Building and sustaining collaboration in cross sector e-learning development

This chapter will focus on the process of building and sustaining collaborative reusable e-learning object development across three educational sectors, Higher Education (HE), the UK National Health Service (NHS) and Further Education (FE) Colleges, using the LOLA project as a case study. A qualitative evaluation of ‘process’ ran alongside the entirety of the LOLA project. This chapter reports the findings of this qualitative research, and analyses how collaboration was achieved between the diverse institutions who were project partners. The strengths of this approach included the commitment of the team members to collaboration, while practical challenges included the location of the team members, but also wider issues in the institutions involved, and in particular, the role of the Media Developer and the perception of it by other team members

Does current analgesia effectively reduce pain in children caused by trauma, within a UK ambulance service. A service evaluation.

Introduction – Pain is one of the most common symptoms presented by patients of all ages to ambulance services, however very few children receive analgesia. Analgesic treatment of pre-hospital injured children is viewed as ‘suboptimal’. The aim of this study was to explore current analgesia given to traumatically injured children in the pre-hospital setting and examine whether a clinically meaningful reduction in pain was achieved. Methods – We evaluated electronic patient report forms over a two-year period (2013–2014) within a UK ambulance service NHS trust. All traumatically injured children within the age range 1–17 with a clinical impression of a fracture, dislocation, wound or burn were included. Patients with a Glasgow Coma Scale of < 15 were excluded. The outcome measure was a reduction in numeric pain rating scale or Wong and Baker faces of 2 or more out of 10. Results – Of the evaluable patients (N = 11,317), 90.8% had a documented pain score, or a reason why a pain score could not be documented. For patients reporting pain (N = 7483), 51.6% (n = 3861) received analgesia, 9.6% (n = 717) received no analgesia but did receive alternative treatment and 38.8% (n = 2905) received no analgesia and no alternative treatment. Morphine sulphate IV, oral morphine, Entonox, paracetamol suspension and poly-analgesia all achieved a clinically meaningful median reduction in pain score; –3.0 (IQR, –5.0 to –2.0), –2.0 (–5.0 to –2.0), –2.0 (–4.0 to –1.0), –2.0 (–4.0 to 0.0) and –3.0 (–4.0 to –1.0), respectively. Conclusions – Analgesia administered to traumatically injured children in the pre-hospital setting within this UK ambulance service NHS trust produces clinically meaningful reductions in pain for these patients. The concern is that a large number of patients received neither analgesia nor alternative treatment. There is a real need to identify barriers to analgesia administration in this patient group

Interventions for preventing non-melanoma skin cancers in high-risk groups

Background Some groups of people have a greater risk of developing common non‐melanoma skin cancers (NMSC). Objectives To evaluate interventions for preventing NMSC in people at high risk of developing NMSC. Search methods We searched the Cochrane Skin Group Specialised Register (March 2007), the Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 1, 2007, MEDLINE (from 2003 to March 2007), EMBASE (from 2005 to March 2007), the metaRegister of Controlled Trials (February 2007). References from trials and reviews were also searched. Pharmaceutical companies were contacted for unpublished trials. Selection criteria Randomised controlled trials of adults and children at high risk of developing NMSC. Data collection and analysis Two review authors independently selected studies and assessed their methodological quality. Main results We identified 10 trials (7,229 participants) that assessed a variety of interventions. One trial found T4N5 liposome lotion significantly reduced the rate of appearance of new BCCs in people with xeroderma pigmentosum. One of three trials of renal transplant recipients showed a significantly reduced risk of new NMSCs when acitretin was compared to placebo (relative risk (RR) 0.22 95% confidence interval (CI) 0.06 to 0.90) and no significant difference in risk of adverse events in two trials (RR 1.80, 95% CI 0.70 to 4.61). In three trials conducted in people with a history of NMSC, the evidence was inconclusive for the development of BCCs for retinol or isoretinoin. However the risk of a new SCC in one trial (HR 1.79, 95% CI 1.16 to 2.76) and adverse events in another trial (RR 1.76, 95% CI 1.57 to 1.97) were significantly increased in the isotretinoin group compared with placebo. In one trial selenium showed a reduced risk of other types of cancer compared with placebo (RR 0.65, 95% CI 0.50 to 0.85) but also a significantly elevated risk of a new NMSC (HR 1.17, 95% CI 1.02 to 1.34). The evidence for one trial of beta‐carotene was inconclusive; and there was a trend towards fewer new NMSC in a trial of a reduced fat diet (RR 0.16, 95% CI 0.02 to 1.31), p = 0.09. Authors' conclusions Some preventative treatments may benefit people at high risk of developing NMSC, but the ability to draw firm conclusions is limited by small numbers of trials, often with one trial per intervention or with inconsistent results between studies

The SINS trial: A randomised controlled trial of excisional surgery versus imiquimod 5% cream for nodular and superficial basal cell carcinoma

<p>Abstract</p> <p>Background</p> <p>Basal cell carcinoma is the commonest human cancer. Despite increasing incidence it remains poorly researched. While not life threatening it can cause significant cosmetic disfigurement. Imiquimod, a cream which enhances the body's immune response, may help deal with the number of cases that occur in low-risk sites, especially when good cosmetic results and home use without surgery are needed.</p> <p>This study aims 1. To compare excisional surgery with imiquimod cream for nodular or superficial basal cell carcinoma in low risk sites, with respect to 3 year clinical clearance, cost-effectiveness and cosmetic results. 2. To ascertain if certain phenotypic features and gene polymorphisms predict tumour responsiveness to treatment.</p> <p>Methods/Design</p> <p>Five hundred participants with low risk nodular or superficial basal cell carcinoma will be recruited from hospitals to this multi-centre, randomised, parallel group, controlled phase III trial. Treatment in the imiquimod group is for 6 weeks for superficial basal cell carcinoma and 12 weeks for nodular basal cell carcinoma. Both treatment groups are followed up in clinic for 3 years. Primary outcome variable: the proportion of participants with clinical evidence of success (no recurrence) at 3 years. The primary outcome will be compared between the two treatment groups. Secondary outcomes include: i) clinical success at 1, 2 and 5 years, ii) time to first recurrence, iii) cosmetic appearance of lesion site after treatment, iv) level of pain, and v) cost-effectiveness. Safety and tolerability data will also be reported.</p> <p>Discussion</p> <p>This study protocol describes a pragmatic randomised controlled trial which it is hoped will address the above uncertainties. Three-year results will be available towards the end of 2010.</p> <p>Trial registration</p> <p>Meta-register: NCT00066872, Eudract No. 2004-004506-24, ISRCTN48755084.</p

Conventional and combination topical photodynamic therapy for basal cell carcinoma:systematic review and meta-analysis

Topical photodynamic therapy (PDT) is an established treatment option for low-risk basal cell carcinoma (BCC).To compare efficacy, cosmesis and tolerability of PDT for BCC with alternative treatments.MEDLINE, PubMed, Embase and CENTRAL databases were searched from inception until 1 September 2017. Included studies were randomized controlled trials (RCTs) of PDT for nodular (n) and superficial (s) BCC reporting at least one of the following outcomes: clearance at 3 months and sustained at 1 or 5 years; recurrence at ≥ 1 year; cosmesis; adverse events; tolerability.From 2331 search results, 15 RCTs (2327 patients; 3509 BCCs) were included. PDT efficacy (5-year sustained clearance) was high but inferior to excisional surgery [nBCC pooled risk ratio (RR) 0·76; 95% confidence interval (CI) 0·63-0·91], and without re-treatment of partially responding lesions, was modestly inferior to imiquimod (sBCC: RR 0·81; 95% CI 0·70-0·95) and similar to fluorouracil (sBCC: RR 0·88; 95% CI 0·75-1·04). Five-year sustained clearance was inferior with conventional vs. fractionated PDT (sBCC: RR 0·76; 95% CI 0·68-0·84). PDT cosmesis was superior to surgery (sBCC: RR 1·68, 95% CI 1·32-2·14; nBCC: RR 1·82, 95% CI 1·19-2·80) and cryosurgery (BCC: RR 3·73, 95% CI 1·96-7·07), and without re-treatment of partially responding lesions was similar to imiquimod (sBCC: RR 1·01, 95% CI 0·85-1·19) and fluorouracil (sBCC: RR 1·04, 95% CI 0·88-1·24). Peak pain was higher but of shorter duration with PDT than topical treatments. Serious adverse reactions were rarer with PDT than imiquimod (sBCC: RR 0·05, 95% CI 0·00-0·84) and fluorouracil (sBCC: RR 0·11, 95% CI 0·01-2·04). Combination PDT regimens demonstrated reduced recurrence and improved cosmesis; however, results from these small studies were often nonsignificant.PDT is an effective treatment for low-risk BCC, with excellent cosmesis and safety. Imiquimod has higher efficacy than single-cycle PDT but more adverse effects. Highest efficacy is with excisional surgery. Fractionated and combination PDT options warrant further study
