‘Our voice started off as a whisper and now it is a great big roar’ : The Salford Dementia Associate Panel as a model of involvement in research activities
This paper presents the work of the ‘Salford Dementia Associate Panel’, based at the Salford Institute for Dementia, Salford University (UK). We discuss the roles of the Dementia Associates, in particular around the areas of engagement and research. The panel is made up of people living with dementia, and current and former care partners. It highlights the development of this group over a four-year period and demonstrates over time how the role of a Dementia Associate member has evolved. The panel is involved in research, education and public engagement activities conducted by staff and students within the Institute. The motivations for becoming involved are clearly articulated and demonstrate how the personal backgrounds of individuals have driven the collective involvement and desire to bring about change. The benefits and challenges associated with working as part of a panel are discussed. We conclude by bringing together our experiences as a set of suggestions for others who may wish to create a similar forum to promote the involvement of people living with dementia and former and current care partners
Identifying interphase vs mitotic cell cycle phases using oxidative stress and a proximity-based null model
Detecting communities in large complex networks has found a wide range of
applications in physical, biological, and social sciences by identifying
mesoscopic groups based on the links between individual units. Moreover,
community detection approaches have been generalized to various data analysis
tasks by constructing networks whose links depend on individual units'
measurements. However, identifying well separated subpopulations in data sets,
e.g., multimodality, still presents challenges due to both the inherent spatial
nature of the resulting networks and the generic emergence of communities in
such networks and the similarity between network structures and
distance-dependent null models. Here we introduce a new spatially informed null
model for this task that takes into account spatial structure but does not
explicitly depend on distances between measurements. We find that community
detection using this null model successfully identifies subpopulations in
multimodal data and accurately does not for unimodal data. We apply this new
null model to the task of identifying interphase vs mitotic cell cycle phases
in a group of Dictyostelium discoideum cells using measurements of oxidative
stress, which have been shown to correlate strongly with cell cycle behaviors
Stigma and the in(visible) perspectives and expectations of home oxygen therapy among people with chronic breathlessness syndrome: A qualitative study
© The Author(s) 2018. Background: Chronic breathlessness syndrome in the context of advancing disease is distressing for all concerned. Oxygen is commonly prescribed in this setting; however, little is known about the perspectives of breathless people who either are on oxygen or are yet to have it prescribed. Aim: To understand and describe the perspectives and experiences of breathless people towards oxygen use at home. Design: This qualitative study utilised an interpretive description approach using semi-structured interviews and thematic analysis. Setting/participants: A total of 19 people with chronic breathlessness syndrome living in South Australia participated in semi-structured interviews. Participants were divided into sub-groups according to whether they were chronically breathless and (1) not using home oxygen (n = 6), (2) using funded home oxygen for severe hypoxaemia (n = 7) and (3) using home oxygen for palliation outside of funding guidelines (n = 6). Results: Three main themes were identified: (1) managing distress and living with chronic breathlessness syndrome, with or without oxygen, requires a range of self-management strategies; (2) expectations of oxygen use: ‘Not as good as I thought it would be’; and (3) the stigma of using oxygen: the visible and invisible. Conclusion: People living with chronic breathlessness struggle daily with both the progression of the underlying disease and the distressing nature of the syndrome. While oxygen does provide benefit for some people, its use and the perceptions of its use are often associated with both the visible and invisible manifestations of stigma. Clinicians need to promote self-management strategies and give careful thought to the prescribing of home oxygen, especially outside the current funding guidelines
The complexity of multidisciplinary respiratory care in amyotrophic lateral sclerosis
Motor neurone disease/amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disorder with no known cure, where death is usually secondary to progressive respiratory failure. Assisting people with ALS through their disease journey is complex and supported by clinics that provide comprehensive multidisciplinary care (MDC). This review aims to apply both a respiratory and a complexity lens to the key roles and areas of practice within the MDC model in ALS. Models of noninvasive ventilation care, and considerations in the provision of palliative therapy, respiratory support, and speech and language therapy are discussed. The impact on people living with ALS of both inequitable funding models and the complexity of clinical care decisions are illustrated using case vignettes. Considerations of the impact of emerging antisense and gene modifying therapies on MDC challenges are also highlighted. The review seeks to illustrate how MDC members contribute to collective decision-making in ALS, how the sum of the parts is greater than any individual care component or health professional, and that the MDC per se adds value to the person living with ALS. Through this approach we hope to support clinicians to navigate the space between what are minimum, guideline-driven, standards of care and what excellent, person-centred ALS care that fully embraces complexity could be
Health-related quality of life in patients with inoperable malignant bowel obstruction: secondary outcome from a double-blind, parallel, placebo-controlled randomised trial of octreotide.
BACKGROUND:This analysis aims to evaluate health-related quality of life (HrQoL) (primary outcome for this analysis), nausea and vomiting, and pain in patients with inoperable malignant bowel obstruction (IMBO) due to cancer or its treatments randomised to standardised therapies plus octreotide or placebo over a maximum of 72 h in a double-blind clinical trial. METHODS:Adults with IMBO and vomiting recruited through 12 services spanning inpatient, consultative and community settings in Australia were randomised to subcutaneous octreotide infusion or saline. HrQoL was measured at baseline and treatment cessation (EORTC QLQ-C15-PAL). Mean within-group paired differences between baseline and post-treatment scores were analysed using Wilcoxon Signed Rank test and between group differences estimated using linear mixed models, adjusted for baseline score, sex, age, time, and study arm. RESULTS:One hundred six of the 112 randomised participants were included in the analysis (n = 52 octreotide, n = 54 placebo); 6 participants were excluded due to major protocol violations. Mean baseline HrQoL scores were low (octreotide 22.1, 95% CI 14.3, 29.9; placebo 31.5, 95% CI 22.3, 40.7). There was no statistically significant within-group improvement in the mean HrQoL scores in the octreotide (p = 0.21) or placebo groups (p = 0.78), although both groups reported reductions in mean nausea and vomiting (octreotide p < 0.01; placebo p = 0.02) and pain scores (octreotide p < 0.01; placebo p = 0.03). Although no statistically significant difference in changes in HrQoL scores between octreotide and placebo were seen, an adequately powered study is required to fully assess any differences in HrQoL scores. CONCLUSION:The HrQoL of patients with IMBO and vomiting is poor. Further research to formally evaluate the effects of standard therapies for IMBO is therefore warranted.

Soft chemical control of superconductivity in lithium iron selenide hydroxides Li1–xFex(OH)Fe1–ySe
Hydrothermal synthesis is described of layered lithium iron selenide hydroxides Li1–xFex(OH)Fe1–ySe (x ∼ 0.2; 0.02 < y < 0.15) with a wide range of iron site vacancy concentrations in the iron selenide layers. This iron vacancy concentration is revealed as the only significant compositional variable and as the key parameter controlling the crystal structure and the electronic properties. Single crystal X-ray diffraction, neutron powder diffraction, and X-ray absorption spectroscopy measurements are used to demonstrate that superconductivity at temperatures as high as 40 K is observed in the hydrothermally synthesized samples when the iron vacancy concentration is low (y < 0.05) and when the iron oxidation state is reduced slightly below +2, while samples with a higher vacancy concentration and a correspondingly higher iron oxidation state are not superconducting. The importance of combining a low iron oxidation state with a low vacancy concentration in the iron selenide layers is emphasized by the demonstration that reductive postsynthetic lithiation of the samples turns on superconductivity with critical temperatures exceeding 40 K by displacing iron atoms from the Li1–xFex(OH) reservoir layer to fill vacancies in the selenide layer
