Artificial neural networks

Roger Watson, Editor-in-Chief

I have long had an interest in artificial neural networks (ANNs) but I must admit my interest was mainly in what they were, what they did and what possible use they could be.  On a visit to Italy many months ago I met a research team at the University of Genoa who were using ANNs to study communication in emergency care.  I encouraged them to publish the work and worked very closely with them and that work is now published in JAN by Bagnasco et al. (2015) in their article titled: 'Applying artificial neural networks to predict communication risks in the emergency department'.

My understanding of ANNs has increased in the process and I am very happy to publish this paper so that others may also learn about them and see their potential in nursing research.  In the words of the authors: 'ANNs are mathematical models that try to imitate the functional processes of the human brain. ANNs involve non-linear relationships among different data sets that cannot always be fully identified through the use of conventional linear analyses. ANNs are extensively used in technology and science with applications in chemistry, physics, biology and medicine.'  I will not pretend that this concept or the operation of ANNs is easy to grasp; however, Bagnasco et al. explain it as clearly as anyone and central to the method, which is computer based, is the 'back propagation algorithm' which allows a system to 'learn' about the data that are being entered into it.

The present study used observational data of 840 nursing communication interactions and used the ANN to analyse which independent demographic variables predicted aspects of communication.  Age and seniority were important variables in increasing effective communication.  I hope that people will study this paper to lean more about ANNs and that we will see more applications of ANNs in nursing research and in the pages of JAN.

Sex after childbirth

Roger Watson, Editor-in-Chief

Many myths surround the issue of sexual activity around childbirth - both pre- and post-natally.  There cannot be a couple who are expecting a child or a woman who is imminently giving birth or has just given birth who does not wonder when they can resume sexual activity, especially  but not exclusively, penetrative vaginal sexual intercourse. 


This issue is addressed by O'Malley et al. (2015) in an article titled: 'Postpartum sexual health: a principle-based concept analysis' and published in JAN.  As the authors explain: 'Postpartum sexual health is a minimally understood concept, most often framed within physical/biological dimensions or as a ‘checklist’ task in postpartum information provision. This has the potential to leave women unprepared to manage transient or normative sexual health changes after childbirth. For meaningful discussions, clarity and understanding of postpartum sexual health is required.'

Using a wide variety of sources which were reviewed systematically the study uses a principle based concept analysis approach to investigate what is know about postpartum sex.  They conclude that: 'Postpartum sexual health is conceptually immature with limited applicability in current midwifery practice.'  Midwives are in an excellent position to advise on postpartum sexual activity but, of course, new mothers (and fathers) may find it hard to ask and, equally, midwives may find the subject difficult to broach.  Finally, in the words of the authors: 'Measurement tools for specifically
assessing and measuring postpartum sexual health were not identified in this analysis and there is a need to develop, test and validate such a tool. Finally, there is limited evidence on the topic from the perspective of midwife care providers and of that which was identified, midwives have apparent
limited knowledge in the area of postpartum sexual health and engage minimally in discussions with women on this topic in the postpartum period. This indicates an urgent need for education in this area, including curriculum considerations at undergraduate and postgraduate level, so that greater clinical understanding and appreciation for this important aspect of maternity care can be assured.'

Dementia Awareness Week UK

Professor John Keady
Dementia and Ageing Research Team, University of Manchester


To mark Dementia Awareness Week, we asked Professor John Keady to select some papers on dementia from JAN.

John Keady
I have chosen six papers to discuss briefly in this blog, with five of the papers published in 2014 and one in 2015. The papers introduce the diversity of dementia as a topic area for research, practice, education and policy and are written by authors from academic institutions around the world. This breadth of active research interest represents the global effort and challenges posed by dementia and the various methodologies necessary to help generate prospective solutions.

The first paper is written by a team of four researchers in Sweden and led by Eva Karlsson, who is named as a PhD student (Karlsson et al. 2014). The primary aim of this paper is to explore how people with Alzheimer’s disease present their own life story and is informed by the contribution of nine participants - five women and four men (age-range 60-81) - all of whom were in the earlier stages of Alzheimer’s disease. Interviews were conducted in the participant’s own homes with the interviews lasting an average of one hour; care partners were reportedly present during this interview period to help provide any contextual/word-finding areas salient to completing the story. However, the focus of the research study and reported experiences was founded squarely on the storyteller, i.e. the person with Alzheimer’s disease. Following transcription, two of the research team led the paradigmatic analysis of the data which led to the generation of four core dimensions that tied together each life story: contentment; connectedness; self-reliance; and personal growth. Interestingly, the dimension of contentment includes a statement that: 'there were, in all stories, also signs of both grief and sadness deriving from emotionally stressful situations in the participant’s lives’ (Karlsson et al. 2014 p.2794). 

This theme of grief and loss is picked up in the second paper by Linauer and Harvath (2014) which undertook a concept analysis of 49 peer-reviewed papers that addressed pre-death grief in family carers of people with dementia. The first author is listed as a doctoral candidate in the USA and the authors included two sources from the popular media that focussed on dementia (a well known book, The Long Goodbye (2014), and the film Iris (2001)) to help frame the presented analysis within an everyday context. Following the study inclusion criteria, the article shared a total of 20 terms for pre-death grief that were contained within the 49 papers and this outlined the complexity in attaching a transparent meaning to the concept. To help provide clarity, the paper systematically compared the characteristics of ‘pre-death grief’, ‘anticipatory grief’ and ‘chronic sorrow’ and whilst the review suggests some ‘blurring’ between the three concepts, differences were also found in the context of family caregiving and dementia. The reporting of these differences enabled the authors to provide a definition of pre-death grief which spun around the caregiver’s ‘emotional and physical response to the perceived losses in a valued care recipient’ (p. 2203). The authors also suggested that pre-death grief can also contribute to caregiver burden, depression and maladaptive coping. 

In a study led by Wang et al. (2014), who is also identified as a PhD student but with an academic base in both China and Australia, the research team continued the focus on family caregiving and dementia. However, this time, the design comprised of an interview-based study which involved 23 participants recruited through geriatric clinics in three university-associated teaching hospitals in China. The sample was made-up of mainly women who had been caring at home for a person with dementia for an average of five years. At its heart, the study was interested in exploring issues that were faced by the participating carers where there was little, if any, expectation of external service support. Of the four themes that emerged from analysis, perhaps unsurprisingly, ‘untreated behavioural and psychological symptoms of dementia’ [the name of the first theme] emerged as a significant cause of family stress, distress and risk. Interestingly, the study participants suggested that beneficial changes would include better coordination between primary and specialist dementia services and that community nurses should have an integral role in this context. 

Papers four, five and six are all drawn from the nursing home setting home setting. Liu (2014) working from the Hong Kong Polytechnic University provides an insightful interview-based study that explored nursing assistant’s role in the identification, treatment and management of pain in a resident with dementia. Changes in a resident’s behaviour, for example through excessive walking or increased vocalisation, could be a sign that the person with dementia is in pain, and the study suggested that the knowledge held by nursing assistants was not always sought by the qualified staff to whom they were responsible. It was an inverse care relationship: the staff with the most familiarity and contact with residents with dementia were given the least autonomy and input into clinical decision-making. A study by Konno et al. (2014) conducted a best evidence review of non-pharmacological interventions for resistance-to-care behaviours of residents with dementia in a personal care context. Intervention studies conducted between 1990-2012 were included in the review and a total of 19 identified, ranging from the implementation of relaxing music at mealtimes to ability-focussed morning care. The evidence for such interventions was persuasive in most instances, but similar to several studies in this blog, the researchers located a number of different descriptive terms that related to the same phenomenon, for instance when looking at approaches to managing agitation. This made cross-comparison difficult. Konno et al. (2014) suggested that standardised terminology would help to build a better platform between researchers, caregivers and practice. The final choice of paper is by Willemse et al. (2015) where the lead researcher is a PhD student based at the VU University Amsterdam. It was selected as it contrasts nicely with the work of Konno et al. (2014) in that in the extensive national survey that sits at centre of this work (n=1093 nursing staff), it was reported that a person-centred workforce is a more effective one. In other words, it is important for nursing homes and managerial systems to create a positive work environment where staff well-being and decision-making is supported and integral to the culture of care. A simple but essential message as the nursing and dementia field moves forward.

Body-mind-spirit and depression

Roger Watson, Editor-in-Chief

A combined team from India and Hong Kong has investigated the use of a body-mind-spirit (BMS) intervention which 'highlights the components of Buddhism, recognition and acceptance of negative emotions, self-love techniques and gaining through pain' for people with depression.  The results are published by Rentala et al. (2105) in JAN in an article titled: 'Effectiveness of body–mind–spirit intervention on well-being, functional impairment and quality of life among depressive patients – a randomized controlled trial'.  

The aim of the project was: 'to examine the effectiveness of BMS intervention in improving outcomes (well-being, quality of life
and functional impairment) among the depressive patients.'  the BMS intervention was tested in a randomised controlled trial against treatment as usual (TAU).  The results showed that: 'Compared with the TAU group, the BMS group showed statistically significant decreases in depression and functional impairment'.

In the words of the authors: 'This is one of the few known studies on the subject which showed that BMS intervention implemented by a nurse was instrumental in bringing about significant changes among Indian depressive patients in terms of reduction in depressive and functional impairment scores, improvement in well-being and quality of life scores.'
