Insights into the impact of clinical encounters gained from personal accounts of living with advanced cancer.

Aim To describe the impact of interactions with health care professionals revealed by people’s accounts of living and dying with cancer; to explore reasons for the observed effects; and thus, to consider the implications for practice. Background The importance of practitioner–patient interactions is enshrined within professional values. However, our understanding of how and why the consultation impacts on outcomes remains underdeveloped. Stories recounted by people living and dying with cancer offer important insights into illness experience, including the impact of contact with health services, framed within the context of the wider social setting in which people live their lives. From our recent study of distress in primary palliative care patients, we describe how people’s accounts revealed both therapeutic and noxious effects of such encounters, and discuss reasons for the observed effects. Method A qualitative study with a purposive sample of 19 primary palliative care patients: (8 men, 11 at high risk of depression). In-depth interviews were analysed using the iterative thematic analysis described by Lieblich. Findings Living with cancer can be an exhausting process. Maintaining continuity of everyday life was the norm, and dependent on a dynamic process of balancing threats and supports to people’s emotional well-being. Interactions with health care professionals were therapeutic when they provided emotional, or narrative, support. Threats arose when the patient’s perception of the professional’s account of their illness experience was at odds with the person’s own sense of their core self and what was important to them. Our findings highlight the need for a framework in which clinicians may legitimately utilize different illness models to deliver a personalized, patient-centred assessment of need and care. The work provides testable hypotheses supporting development of understanding of therapeutic impact of the consultation

A waste heat recovery strategy for an integrated steelworks

UK energy prices have doubled over the last decade, which has driven the UK Iron and Steel Industry to invest in energy efficient technologies. However, even with these relatively high prices the industry still finds it difficult to build a business case to justify waste heat recovery projects. The Steel Industry has large quantities of waste heat and there are technologies readily available for its capture, but often the issue has been finding a cost effective ‘end use’. Individual schemes incorporating both capturing and an ‘end use’ for the waste heat often incur high capital costs with resulting long payback times. This thesis defines the development and modelling of a strategy and methodology for the utilisation of waste heat recovery in a UK based Steelworks. The methodology involves the utilisation of the existing steam distribution circuit to link the possible waste heat schemes together with a single ‘end user’ thus limiting the capital requirement for each subsequent project. The thesis defines the development of a numerical model that is initially verified through extensive comparison to actual plant data from a series of pre-defined operational scenarios. The model is used to predict the pressure and temperature effects on the steam distribution system as the waste heat recovery boilers from various areas of the case study steelworks are connected up to it. The developed strategy stimulated significant capital investment for the CSSW and has generated over 100,000 MWh and is therefore saving over £7m and 50,000 tonnes of indirect CO2 emissions per annum. The thesis discusses and recommends further research and modelling for low, medium and high grade waste heat as well as the potential of a partial de-centralisation of the steam system. The output of the thesis is referenced by the DECC as an example of waste heat recovery in UK industry

The role of day care in supporting older people living with long-term conditions.

Purpose of reviewFor older people with long-term conditions, regular structured activities within a community setting meeting others are thought to improve well being and quality of life. Historically local authority-run day care centres were widely available, but austerity measures have meant that in many areas, such provision has been markedly reduced and different models of day care services are being developed. There is little known about outcomes of day care provision for older people with long-term conditions.Recent findingsThis review has critically examined the recent evidence on outcomes of day care provision for older people with long-term conditions and will focus on three areas - physical functioning, intergenerational provision and measurement of outcomes. In terms of interventions to improve physical functioning for older people with long-term conditions attending day care, there are few studies and it is difficult to generalize but there appears to be a trend for positive impact on physical functioning when activities are incorporated into a day care programme. There is a paucity of research on intergenerational provision, however, the small number of studies suggest positive benefits. Studies measuring outcomes for older people with long-term conditions attending day care services are very limited in terms of outcome data with the exception of a Canadian study, which suggested that attendance at day care could reduce hospital attendance and admissions.SummaryThis review reveals a lack of research of day care provision for older people with long-term conditions. There is a suggestion in the small number of articles included in this review that there can be benefits both in terms of global outcomes of attendance and in improved physical functioning; there is limited evidence of the value of intergenerational provision. Robust research with collection of meaningful outcomes is required to ensure that the increasing number of older people with long-term conditions are enabled to access high-quality day care provision

Feasibility of patient reported outcome measures in psychosocial palliative care: Observational cohort study of hospice day care and social support groups

Palliative care patients can be at risk of social isolation or loneliness. Interventions that can provide effective social support, and particularly emotional support, could facilitate healthy coping that bolsters quality of life and reduces depression in palliative care patients. This is an observational cohort study which recruited thirty patients (n = 30) from the day services of four independent hospices in England. Participants completed patient reported outcome measures in perceived social support, loneliness, and depression, at up to three time points. Age range was 56–91 years, males and females were equally represented, and the sample was 93% white British. In participants that provided two or more timepoints, perceived social support increased, and loneliness and depression decreased. Largest changes with the least variation between participants was in emotional support (p = 0.165) and loneliness (p = 0.104). These results suggest that the psychosocial patient reported outcome measures used (MOS-SS, UCLA, BEDS) could be sensitive to change aligned with the goals of this intervention in palliative care. Participants in this study were observed to derive psychosocial benefit from attending the hospice day service

Impact of CTLA-4 checkpoint antibodies on ligand binding and Transendocytosis

Anti-CTLA-4 antibodies have pioneered the field of tumour immunotherapy. However, despite impressive clinical response data, the mechanism by which anti-CTLA-4 antibodies work is still controversial. Two major checkpoint antibodies (ipilimumab and tremelimumab) have been trialled clinically. Both have high affinity binding to CTLA-4 and occupy the ligand binding site, however recently it has been suggested that in some settings such antibodies may not block ligand-CTLA-4 interactions. Here we evaluated blocking capabilities of these antibodies in a variety of settings using both soluble and cell bound target proteins. We found that when ligands (CD80 or CD86) were expressed on cells, soluble CTLA-4-Ig bound in line with affinity expectations and that this interaction was effectively disrupted by both ipilimumab and tremelimumab antibodies. Similarly, cellular CTLA-4 binding to soluble ligands was comparably prevented. We further tested the ability of these antibodies to block transendocytosis, whereby CTLA-4 captures ligands from target cells during a cognate cell-cell interaction. Once again ipilimumab and tremelimumab were similar in preventing removal of ligand by transendocytosis. Furthermore, even once transendocytosis was ongoing and cell contact was fully established, the addition of these antibodies could prevent further ligand transfer. Together these data indicate that the above checkpoint inhibitors performed in-line with predictions based on affinity and binding site data and are capable of blocking CTLA-4-ligand interactions in a wide range of settings tested

The palatability of sugar-sweetened beverage taxation: A content analysis of newspaper coverage of the UK sugar debate

Background: Excess sugar consumption, including sugar-sweetened beverages (SSBs), contributes to a variety of negative health outcomes, particularly for young people. The mass media play a powerful role in influencing public and policy-makers’ perceptions of public health issues and their solutions. We analysed how sugar and SSB policy debates were presented in UK newspapers at a time of heightened awareness and following the announcement of the UK Government’s soft drinks industry levy (SDIL), to inform future public health advocacy. Methods and Findings: We carried out quantitative content analysis of articles discussing the issues of sugar and SSB consumption published in 11 national newspapers from April 2015 to November 2016. 684 newspaper articles were analysed using a structured coding frame. Coverage peaked in line with evidence publication, campaigner activities and policy events. Articles predominantly supportive of SSB taxation (23.5%) outnumbered those that were predominantly oppositional (14.2%). However, oppositional articles outnumbered supportive ones in the month of the announcement of the SDIL. Sugar and SSB consumption were presented as health risks, particularly affecting young people, with the actions of industry often identified as the cause of the public health problem. Responsibility for addressing sugar overconsumption was primarily assigned to government intervention. Conclusion: Our results suggest that the policy landscape favouring fiscal solutions to curb sugar and SSB consumption has benefited from media coverage characterising the issue as an industry-driven problem. Media coverage may drive greater public acceptance of the SDIL and any future taxation of products containing sugar. However, future advocacy efforts should note the surge in opposition coinciding with the announcement of the SDIL, which echoes similar patterns of opposition observed in tobacco control debates

Microbial impacts on 99mTc migration through sandstone under highly alkaline conditions relevant to radioactive waste disposal

Geological disposal of intermediate level radioactive waste in the UK is planned to involve the use of cementitious materials, facilitating the formation of an alkali-disturbed zone within the host rock. The biogeochemical processes that will occur in this environment, and the extent to which they will impact on radionuclide migration, are currently poorly understood. This study investigates the impact of biogeochemical processes on the mobility of the radionuclide technetium, in column experiments designed to be representative of aspects of the alkali-disturbed zone. Results indicate that microbial processes were capable of inhibiting 99mTc migration through columns, and X-ray radiography demonstrated that extensive physical changes had occurred to the material within columns where microbiological activity had been stimulated. The utilisation of organic acids under highly alkaline conditions, generating H2 and CO2, may represent a mechanism by which microbial processes may alter the hydraulic conductivity of a geological environment. Column sediments were dominated by obligately alkaliphilic H2-oxidising bacteria, suggesting that the enrichment of these bacteria may have occurred as a result of H2 generation during organic acid metabolism. The results from these experiments show that microorganisms are able to carry out a number of processes under highly alkaline conditions that could potentially impact on the properties of the host rock surrounding a geological disposal facility for intermediate level radioactive waste
