Innovating urinary catheter design: an introduction to the engineering challenge
No full textEvery day, people around the world rely on intermittent and indwelling urinary catheters to manage bladder dysfunction, but the potential or actual harm caused by these devices is well-recognised. Current catheter designs can cause urinary tract infection and septicaemia, bladder and urethral trauma and indwelling devices frequently become blocked. Furthermore, the devices can severely disrupt users’ lives, limiting their daily activities and can be costly to manage for healthcare providers. Despite this, little significant design innovation has taken place in the last 80 years. In this article current catheter designs and their limitations are reviewed, common catheter-associated problems are outlined and areas of design ripe for improvement proposed. The potential to relieve the individual and economic burden of catheter use is high
Experiences and impact of living with incontinence associated stigma: A protocol for a systematic review and narrative synthesis of qualitative studies
No full textINTRODUCTION: Incontinence is global health and social issue, with urinary incontinence alone affecting over 400 million people. Incontinence can lead to physical harms such as skin damage, but it also commonly causes social and psychological harms, including those associated with stigma. For many people, treatment to cure incontinence does not work or is not suitable and they live with the long-term consequences of incontinence. At the moment, no stigma reduction interventions (increasingly used with other conditions such as mental health problems and HIV) have been developed for people living with incontinence. As a starting point for developing such an intervention, this review will address the questions 1) What are the incontinence (urinary or faecal) associated experiences of stigma of people living with incontinence? 2) What is the impact of incontinence associated stigma on their lives? METHODS: The reviewers will search Embase, Medline, PsychINFO and the Cumulative Index to Nursing and Allied Health Literature using controlled vocabulary and relevant search terms. Articles assessed to meet inclusion criteria will be included. Once duplicates have been removed, titles and abstracts will be screened and full texts of selected research articles will be reviewed. An adapted Joanna Briggs Institute Data Extraction Form will be used to collect the data and quality will be assessed using the Joanna Briggs Institute checklist for qualitative research appraisal tool. A framework approach (using the Revised Framework for Understanding Non-communicable Disease Related Stigma) will be used to organise, integrate, interpret and summarise findings from included articles. The review will be reported in accordance with the Enhancing Transparency in reporting the synthesis of qualitative research statement. Prospero registration number CRD42021259065. DISCUSSION: The systematic review described in this protocol will provide the first in-depth, comprehensive understanding of people’s experiences of the stigma associated with incontinence and the impact that it has on their lives. It will identify broader influences of contextual variables such as age, sex, cause and type of incontinence, socio-economic culture and geographical location. The review aims to provide insights to support the development of incontinence associated stigma reduction interventions
A qualitative study of continence service provision for people living with dementia at home in the UK: Still inadequate?
No full textINTRODUCTION: Incontinence is a major problem for people with dementia (PWD) and their family/friend caregivers, often causing substantial harm, including residential care admission. The incontinence needs of PWD are complex and different from those of people without dementia. The aim of this study was to investigate carer and nurse perceptions of continence service provision and potential improvements.METHODS: A secondary analysis of qualitative data was undertaken. Semi-structured interviews (n = 45) were undertaken with PWD, family caregivers and healthcare professionals (continence or dementia nurses) in the UK. PWD and caregivers were recruited via www.joindementiaresearch.nihr.ac.uk and via dementia/carer groups. Nurses were recruited via their employers. Framework analysis was used. The COREQ Research guideline statement assists reporting.RESULTS: Four themes were found. Firstly, there was a lack of awareness of the service and waiting time. Many caregivers were unaware of continence services and dementia nurses often viewed it as a pad provision service. Caregivers reported long waits not meeting their urgent needs. Secondly, product provision was often inadequate. Most caregivers self-purchased all or many products and substantial variation in product provision was found. The number of products provided was often inadequate. Thirdly, a sense that "nothing can be done" was observed by some nurses and caregivers. Caregivers believed that, if nothing else, care information should be provided. Finally, suggestions for improvements were made, including proactive service signposting, joint clinics with dementia services, improved information before crisis point, dementia training for continence nurses and improved product provision.CONCLUSION: Continence service inadequacies for PWD and caregivers have been reported for many years. This study demonstrates service provision remains unsatisfactory in the UK. Stakeholders propose a range of service improvements. It highlights that listening to the voices of PWD, caregivers and nurses is crucial for services seeking to improve continence services for PWD living at home.</p
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
A multicentre exploratory study of the impact of urinary incontinence in the 6 weeks after catheter removal following radical prostatectomy
No full textA common complication of radical prostatectomy surgery is the sudden onset of urinary incontinence (UI), with most men experiencing at least transient post‐surgery UI [1]. Carrier et al.’s [1] recent meta‐synthesis of qualitative studies on men’s perceptions of the impact of physical symptoms post radical prostatectomy on their quality of life found that UI is a “significant problem for which men feel ill‐prepared” (p.13). In the post‐operative weeks, men must cope with the practicalities of effectively containing urine, whilst also dealing with the psychological burden of sudden onset incontinence which can cause a “second shock following the initial shock of the diagnosis” [2]
Innovating indwelling catheter design to counteract urinary tract infection
No full textBackground and objective: bacteriuria is anticipated in long-term indwelling catheter (IDC) use, and urinary tract infections (UTIs) and related issues are common. Defence mechanisms against infection are undermined by the presence of a Foley catheter, and adjustments to design could influence UTI risk.Methods: we reviewed the various aspects of IDCs and ureteric stent designs to discuss potential impact on UTI risk.Key findings and limitations: design adaptations have focussed on reducing the sump of undrained urine, potential urinary tract trauma, and bacterial adherence. Experimental and computational studies on ureteral stents found an interplay between urine flow, bacterial microcolony formation, and accumulation of encrusting particles. The most critical regions for biofilm and crystal accumulation are associated with low shear stress. The full drainage system is the functioning unit, not just the IDC in isolation. This means reliably keeping the drainage system closed and considering whether a valve is preferred to a collection bag. Other developments may include one-way valves, obstacles to “bacterial swimming”, and ultrasound techniques. Preventing or clearing IDC blockage can exploit access via the lumen or retaining balloon. Progress in computational fluid dynamics, energy delivery, and soft robotics may increase future options. Clinical data on the effectiveness of IDC design features are lacking, which is partly due to reliance on proxy measures and the challenges of undertaking trials.Conclusions and clinical implications: design changes are legitimate lines of development, but are only indirect for UTI prevention. Modifications may be advantageous, but might potentially bring problems in other ways. Education of health care professionals can improve UTIs and should be prioritised.Patient summary: catheters used to help bladder drainage can cause urinary infections, and improvements in design might reduce the risk. Several approaches are described in this review. However, proving that these approaches work is a challenge. Training professionals in the key aspects of catheter care is important
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
