Processing bodies are dynamically localised and associate with multiple organelles throughout the replicative lifespan of the yeast cell

Processing bodies (p-bodies) are cytoplasmic messenger ribonucleoprotein granules containing components of the mRNA degradation machinery, that form during stress conditions in the budding yeast Saccharomyces cerevisiae. P-bodies are conserved in eukaryotes and are related to other mRNP granules such as stress granules and neuronal granules. mRNP granules and their components self-assemble through a process of liquid-liquid phase separation, facilitated by protein-protein interaction by low complexity regions. Errors in this assembly process can cause a build-up of aggregated protein and have been implicated in the pathology of human neurodegenerative diseases such as amyotrophic lateral sclerosis. The exact role of p-bodies in normal cellular function is not known, but p-bodies are induced in conditions of stress, and can store mRNA that later re-enters translation, leading to the theory that they are sites of mRNA storage. A contrasting theory suggests them as sites of mRNA decay, due to the presence of deadenylation, decapping and exonuclease complexes within p-bodies. In this work, time-lapse fluorescence microscopy, using optimised high brightness, low photobleaching fluorescent protein fusions, was used to allow long term imaging of p-body localisation throughout the cell cycle of S. cerevisiae. Imaging was combined with microfluidic dissection of mother and daughter cells, to track single mother cells over their entire replicative lifespan (RLS) while continuing to monitor p body localisation. P-bodies were found to be localised in proximity to multiple different organelles with changes to localisation occurring through the cell cycle. Advanced replicative aged altered the profile of p-body localisation causing p-bodies to localise heavily to the mitochondria. P-bodies were also found to be inherited by daughter cells in a process dependent on the mRNA transport machinery and the p-body protein Dcp1. This inheritance was multigenerational with a single p-body moving between multiple daughter cells and was not lost in cells of advanced replicative age

Is seeing a specialist nurse associated with positive experiences of care? The role and value of specialist nurses in prostate cancer care

<p>Abstract</p> <p>Background</p> <p>Specialist nurses may play an important role in helping to improve the experiences of patients with prostate cancer, however there is concern that the specialist nurse role is under threat in the UK due to financial pressures in the NHS. This study explored the role and value of specialist nurses in prostate cancer care via a survey and patient interviews.</p> <p>Methods</p> <p>This paper reports findings from two studies. A survey of patients from three hospitals across the UK (289/481, 60%), investigated whether patients who saw a specialist nurse had different experiences of information provision and involvement in decision-making, to those who did not. Qualitative interviews were also carried out with 35 men recently tested or treated for prostate cancer, recruited from two hospitals in the UK. Interviews explored patients' views on the role and value of the specialist nurse.</p> <p>Results</p> <p>Survey findings indicated that patients who saw a specialist nurse had more positive experiences of receiving written information about tests and treatment, and about sources of advice and support, and were more likely to say they made the treatment decision themselves. In interviews, patients described specialist nurse input in their care in terms of providing information and support immediately post-diagnosis, as well as being involved in ongoing care. Two key aspects of the specialist nurse role were seen as unique: their availability to the patient, and their ability to liaise between the patient and the medical system.</p> <p>Conclusion</p> <p>This study indicates the unique role that specialist nurses play in the experience of patients with prostate cancer, and highlights the importance of maintaining specialist nurse roles in prostate cancer care.</p

Antimicrobial drugs for persistent diarrhoea of unknown or non-specific cause in children under six in low and middle income countries: systematic review of randomized controlled trials

Background A high proportion of children with persistent diarrhoea in middle and low income countries die. The best treatment is not clear. We conducted a systematic review to evaluate the effectiveness of antimicrobial drug treatment for persistent diarrhoea of unknown or non-specific cause. Methods We included randomized comparisons of antimicrobial drugs for the treatment of persistent diarrhoea of unknown or non-specific cause in children under the age of six years in low and middle income countries. We searched the electronic databases MEDLINE, EMBASE, LILACS, WEB OF SCIENCE, and the Cochrane Central Register of Controlled Trials (CENTRAL) to May 2008 for relevant randomized or quasi randomized controlled trials. We summarised the characteristics of the eligible trials, assessed their quality using standard criteria, and extracted relevant outcomes data. Where appropriate, we combined the results of different trials. Results Three trials from South East Asia and one from Guatemala were included, all were small, and three had adequate allocation concealment. Two were in patients with diarrhoea of unknown cause, and two were in patients in whom known bacterial or parasitological causes of diarrhoea had been excluded. No difference was demonstrated for oral gentamicin compared with placebo (presence of diarrhoea at 6 or 7 days; 2 trials, n = 151); and for metronidazole compared with placebo (presence of diarrhoea at 3, 5 and 7 days; 1 trial, n = 99). In one small trial, sulphamethoxazole-trimethoprim appeared better than placebo in relation to diarrhoea at seven days and total stool volume (n = 55). Conclusion There is little evidence as to whether or not antimicrobials help treat persistent diarrhoea in young children in low and middle income countries

The impact of patient participation direct enhanced service on patient reference groups in primary care: a qualitative study.

NHS policy documents continue to make a wide-ranging commitment to patient involvement. The Patient Participation Direct Enhanced Service (PP-DES), launched in 2011, aimed to ensure patients are involved in decisions about the range and quality of services provided and commissioned by their practice through patient reference groups (PRGs). The aim of this exploratory study is to review the impact of the PP-DES (2011-13) on a sample of PRGs and assess how far it has facilitated their involvement in decisions about the services of their general practices.The National Institute for Health Research (NIHR) Collaboration for Leadership in Applied Health Research and Care (CLAHRC) for Leicestershire, Northamptonshire and Rutland (LNR)

The National Institute of Health Research (NIHR) Collaboration for Leadership in Applied Health Research and Care (CLAHRC) for Leicestershire, Northamptonshire and Rutland (LNR): a programme protocol

<p>Abstract</p> <p>Background</p> <p>In October 2008, the National Institute for Health Research launched nine new research projects to develop and investigate methods of translating research evidence into practice. Given the title Collaborations for Leadership in Applied Health Research and Care (CLAHRC), all involve collaboration between one or more universities and the local health service, but they are adopting different approaches to achieve translation.</p> <p>Methods</p> <p>The translation and implementation programme of this CLAHRC has been built around a pragmatic framework for undertaking research to address live concerns in the delivery of care, in partnership with the managers, practitioners, and patients of the provider organisations of the CLAHRC. Focused on long-term conditions, the constituent research themes are prevention, early detection, self-management, rehabilitation, and implementation. Individual studies have various designs, and include both randomised trials of new ways to deliver care and qualitative studies of, for example, means of identifying barriers to research translation. A mix of methods will be used to evaluate the CLAHRC as a whole, including use of public health indicators, social research methods, and health economics.</p> <p>Discussion</p> <p>This paper describes one of the nine collaborations, that of Leicestershire, Northamptonshire, and Rutland. Drawing a distinction between translation as an organising principle for healthcare providers and implementation as a discrete activity, this collaboration is built on a substantial programme of applied research intended to create both research generation and research use capacity in provider organisations. The collaboration in Leicestershire, Northamptonshire, and Rutland has potential to provide evidence on how partnerships between practitioners, patients, and researchers can improve the transfer of evidence into practice.</p

The Prostate Care Questionnaire for Carers (PCQ-C): reliability, validity and acceptability

<p>Abstract</p> <p>Background</p> <p>Patient experience is commonly monitored in evaluating and improving health care, but the experience of carers (partners/relatives/friends) is rarely monitored even though the role of carers can often be substantial. For carers to fulfil their role it is necessary to address their needs. This paper describes an evaluation of the reliability, validity and acceptability of the PCQ-C, a newly developed instrument designed to measure the experiences of carers of men with prostate cancer.</p> <p>Methods</p> <p>The reliability, acceptability and validity of the PCQ-C were tested through a postal survey and interviews with carers. The PCQ-C was posted to 1087 prostate cancer patients and patients were asked to pass the questionnaire on to their carer. Non-responders received one reminder. To assess test-retest reliability, 210 carers who had responded to the questionnaire were resent it a second time three weeks later. A subsample of nine carers from patients attending one hospital took part in qualitative interviews to assess validity and acceptability of the PCQ-C. Acceptability to service providers was evaluated based on four hospitals' experiences of running a survey using the PCQ-C.</p> <p>Results</p> <p>Questionnaires were returned by 514 carers (47.3%), and the majority of questions showed less than 10% missing data. Across the sections of the questionnaire internal consistency was high (Cronbach's alpha ranging from 0.80 to 0.89), and test-retest stability showed moderate to high stability (intraclass correlation coefficients ranging from 0.52 to 0.83). Interviews of carers indicated that the PCQ-C was valid and acceptable. Feedback from hospitals indicated that they found the questionnaire useful, and highlighted important considerations for its future use as part of quality improvement initiatives.</p> <p>Conclusions</p> <p>The PCQ-C has been found to be acceptable to carers and service providers having been used successfully in hospitals in England. It is ready for use to measure the aspects of care that need to be addressed to improve the quality of prostate cancer care, and for research.</p

A mobile ecology of resources for Covid-19 learning

Mobile devices and a vast array of accompanying applications offer significant affordances to create, consume, share, collaborate and communicate—affordances that could be easily leveraged to facilitate meaningful learning. A positive disruption arising from Covid-19 that aligns with the affordances of mobile learning is the uncoupling of time and space in the learning process. Traditionally formal learning is a process that is predominately viewed as an experience that is ‘timetabled’— scheduled to eventuate at a ‘place’—lecture or a tutorial (or similar) in a room or lecture theatre. In this concise paper, an ecology of resources is discussed along with guiding principles for designing and facilitating uncoupled authentic and student-determined learning post the emergency remote teaching phase

The Prostate Care Questionnaire for Patients (PCQ-P): Reliability, validity and acceptability

<p>Abstract</p> <p>Background</p> <p>In England, prostate cancer patients report worse experience of care than patients with other cancers. However, no standard measure of patient experience of prostate cancer care is currently available. This paper describes an evaluation of the reliability, validity and acceptability of the PCQ-P, a newly developed instrument designed to measure patient experience of prostate cancer care.</p> <p>Methods</p> <p>The reliability, acceptability and validity of the PCQ-P were tested through a postal survey and interviews with patients. The PCQ-P was posted to 1087 prostate cancer patients varying in age, occupation, and overall health status, sampled from five hospitals in England. Nonresponders received one reminder. To assess criterion validity, 935 patients were also sent sections of the National Centre for Social Research Shortened Questionnaire; and to assess test-retest reliability, 296 patients who responded to the questionnaire were resent it a second time three weeks later. A subsample of 20 prostate cancer patients from one hospital took part in qualitative interviews to assess validity and acceptability of the PCQ-P. Acceptability to service providers was evaluated based on four hospitals' experiences of running a survey using the PCQ-P.</p> <p>Results</p> <p>Questionnaires were returned by 865 patients (69.2%). Missing data was low across the sections, with the proportion of patients completing less than 50% of each section ranging from 4.5% to 6.9%. Across the sections of the questionnaire, internal consistency was moderate to high (Cronbach's alpha ranging from 0.63 to 0.80), and test-retest stability was acceptable (intraclass correlation coefficients ranging from 0.57 to 0.73). Findings on criterion validity were significant. Patient interviews indicated that the PCQ-P had high face validity and acceptability. Feedback from hospitals indicated that they found the questionnaire useful, and highlighted important considerations for its future use as part of quality improvement initiatives.</p> <p>Conclusion</p> <p>The PCQ-P has been found to be acceptable to patients and service providers, and is ready for use for the measurement of patient experience in routine practice, service improvement programmes, and research.</p
