Patient's best interest as viewed by nursing students

BACKGROUND

In recent years, patient advocacy has emerged as a prominent concept within healthcare. How nursing students decide what is best for their patients is not well understood.

OBJECTIVE

The objective is to examine nursing students' views on doing what is best for patients during their clinical experiences and how they seek to establish patient interests when providing care. Research questions guiding the interview were as follows: (1) What are nursing students' perceptions of patient interests? (2) What factors influence nursing students' perceptions of advocating for patient's interests?

RESEARCH DESIGN

Qualitative descriptive research using thematic analysis.

PARTICIPANTS AND RESEARCH CONTEXT

Data was collected through individual online interviews with nine nursing students with clinical experience.

ETHICAL CONSIDERATIONS

The study was approved by the University Research Ethics Committee. Participants provided digital informed consent.

RESULTS

The students asserted that they are able to understand the patients' interests by placing emphasis on the patients' needs. They believe that it is crucial to adopt a collaborative strategy for the provision of care to meet these requirements. In addition, some of them expressed concern over the most effective methods of advocating for the interests of patients. Three themes were identified. (1) Focussing on patient needs first, (2) taking a collective approach, and (3) learning how to advocate.

CONCLUSIONS

Students understand and value the ethical commitments associated with advocating for the patient's best interest by considering factors such as prioritising the patient's needs, adopting a strategy that involves everyone, and acquiring the ability to undertake the advocacy role. Additionally, nursing education strategies in clinical contexts require additional study to inspire students to do what is in their patient's best interests.

Realist Approach to Qualitative Data Analysis

BACKGROUND

A realist approach has gained popularity in evaluation research, particularly in understanding causal explanations of how a program works (or not), the circumstances, and the observed outcomes. In qualitative inquiry, the approach has contributed to better theoretically based explanations regarding causal interactions.

OBJECTIVE

The aim of this study was to discuss how we conducted a realist-informed data analysis to explore the causal interactions within qualitative data.

METHODS

We demonstrated a four-step realist approach of retroductive theorizing in qualitative data analysis using a concrete example from our empirical research rooted in the critical realism philosophical stance. These steps include (a) category identification, (b) elaboration of context-mechanism-outcome configuration, (c) demi-regularities identification, and (d) generative mechanism refinement.

RESULTS

The four-step qualitative realist data analysis underpins the causal interactions of important factors and reveals the underlying mechanisms. The steps produce comprehensive causal explanations that can be used by related parties-especially when making complex decisions that may affect wide communities.

DISCUSSION

The core process of realist data analysis is retroductive theorizing. The four-step qualitative realist data analysis facilitates this theorizing by allowing the researcher to identify (a) patterns, (b) fluctuation of patterns, (c) mechanisms from collected data, and (d) to confirm proposed mechanisms.

Perspectives on barriers and facilitators to lifestyle change after cardiac events among patients in Saudi Arabia: a qualitative study

AIMS

Lifestyle interventions are an essential element in the prevention of cardiovascular disease. However, promoting a healthy lifestyle is challenging because a multitude of factors interact and influence people's decisions to adopt and maintain healthy lifestyles. The effects of these factors on Saudi cardiac patients are largely unknown. This study aimed to explore the barriers and facilitators to healthy lifestyle changes among Saudis after cardiac events.

METHODS AND RESULTS

The study followed an exploratory qualitative research design, using a social ecological approach. Semi-structured interviews were conducted with 21 participants (13 men and 8 women) who had a cardiac event. Participants were purposively recruited from cardiac clinics of two hospitals in Jeddah, Saudi Arabia. Data were analysed using the qualitative framework analysis, and factors were identified as salient based on their frequency and the potential strength of their impact. Six factors were identified as influencing lifestyle behaviours in cardiac patients, categorized as 'major' factors and 'mediating' factors. The 'major' factors were sociocultural norms, family values, and religious beliefs, and the mediating factors were insufficient healthcare services, physical environment, and policy regulations. Depending upon the behaviours reported and the context, the same factor could be classified as both a barrier and a facilitator.

CONCLUSION

The findings of this study can be used to inform the development of contextual-based interventions to promote the adoption of healthy lifestyles that meet the population needs and are relevant to Saudi society.

Costs and clinical benefits of enhanced recovery after surgery (ERAS) in pancreaticoduodenectomy: an updated systematic review and meta-analysis

PURPOSE

ERAS is a holistic and multidisciplinary pathway that incorporates various evidence-based interventions to accelerate recovery and improve clinical outcomes. However, evidence on cost benefit of ERAS in pancreaticoduodenectomy remains scarce. This review aimed to investigate cost benefit, compliance, and clinical benefits of ERAS in pancreaticoduodenectomy.

METHODS

A comprehensive literature search was conducted on Medline, Embase, PubMed, CINAHL and the Cochrane library to identify studies conducted between 2000 and 2021, comparing effect of ERAS programmes and traditional care on hospital cost, length of stay (LOS), complications, delayed gastric emptying (DGE), readmission, reoperation, mortality, and compliance.

RESULTS

The search yielded 3 RCTs and 28 cohort studies. Hospital costs were significantly reduced in the ERAS group (SMD = - 1.41; CL, - 2.05 to - 0.77; P < 0.00001). LOS was shortened by 3.15 days (MD = - 3.15; CI, - 3.94 to - 2.36; P < 0.00001) in the ERAS group. Fewer patients in the ERAS group had complications (RR = 0.83; CI, 0.76-0.91; P < 0.0001). Incidences of DGE significantly decreased in the ERAS group (RR = 0.72; CI, 0.55-0.94; P = 0.01). The number of deaths was fewer in the ERAS group (RR = 0.76; CI, 0.58-1.00; P = 0.05).

CONCLUSION

This review demonstrated that ERAS is safe and feasible in pancreaticoduodenectomy, improves clinical outcome such as LOS, complications, DGE and mortality rates, without changing readmissions and reoperations, while delivering significant cost savings. Higher compliance is associated with better clinical outcomes, especially LOS and complications.

The characteristics of effective technology-enabled dementia education: a systematic review and mixed research synthesis

BACKGROUND

Dementia education is required to address gaps in dementia-specific knowledge among health and social care practitioners amidst increasing dementia prevalence. Harnessing technology for dementia education may remove obstacles to traditional education and empower large communities of learners. This systematic review aimed to establish the technological and pedagogical characteristics associated with effective technology-enabled dementia education for health and social care practitioners.

METHODS

MEDLINE, PubMed, Web of Science, CINAHL, Scopus, PsycINFO, ERIC and OVID Nursing Database were searched from January 2005 until February 2020. Quantitative, qualitative and mixed methods studies were eligible for inclusion. Study quality was assessed with the Mixed Methods Appraisal Tool. Quantitative evidence was categorised based on Kirkpatrick's Model. Qualitative data was synthesised thematically and integrated with quantitative findings before conclusions were drawn.

RESULTS

Twenty-one published papers were identified. Participants were acute, primary and long-term care practitioners, or were students in higher education. Most training was internet-based; CD-ROMs, simulations and tele-mentoring were also described. Technology-enabled dementia education was predominantly associated with positive effects on learning outcomes. Case-based instruction was the most frequently described instructional strategy and videos were common modes of information delivery. Qualitative themes emerged as existing strengths and experience; knowledge gaps and uncertainty; developing core competence and expertise; involving relevant others; and optimising feasibility.

DISCUSSION

Technology-enabled dementia education is likely to improve dementia knowledge, skills and attitudes among health and social care practitioners from multiple practice contexts. Confidence in the results from quantitative studies was undermined by multiple confounding factors that may be difficult to control in the educational research context. Convenience and flexibility are key benefits of technology-enabled instructive and simulated pedagogy that can support the application of theory into practice. More research is required to understand the role of online learning networks and provisions for equitable engagement. A future emphasis on organisational and environmental factors may elucidate the role of technology in ameliorating obstacles to traditional dementia education.

Emergency department nurses' role transition towards emergency nurse practitioner: A realist-informed review

BACKGROUND

The integration of emergency nurse practitioner (ENP) services in emergency departments (EDs) has been well established, especially in high-income countries such as the United Kingdom, the United States and Australia. Different types of reviews, including integrative, literature and systematic, have been carried out to examine evidence regarding the impact of ENPs on the quality of ED services. Unfortunately, there is still limited explanation of the influencing factors that may result in a successful transition process from Registered Nurse to Emergency Nurse Practitioner. This review aims to understand these factors.

METHODS

A realist approach (RAMESES) guided this review. CINAHL Plus, MEDLINE, PsycINFO, EMBASE and Web of Science databases were searched to capture studies from 1990 to 2020, combined with policy documents from professional bodies and government websites and relevant references from identified sources. Realist data analysis was carried out on the included articles to understand how context, mechanism and outcomes related to the ED nurses' role transition.

RESULTS

Forty-eight articles were included. There were differences in preparatory education and scope of practice of the role. The review configured various contexts, mechanisms and outcomes of the role transition along with their interactions.

CONCLUSION

The findings provide a comprehensive understanding regarding the emergency nurses' role transition, with a view to providing better insights and explanations to interested parties who would like to integrate the ENP service in their ED.

Young Adults Rehabilitation Needs and Experiences following Stroke (YARNS): A review of digital accounts to inform the development of age-appropriate support and rehabilitation

AIMS

To explore younger adults' experiences of stroke rehabilitation to inform practice, education and future health policy.

DESIGN

Qualitative analysis of digital and other media sources on public platforms.

METHODS

Between March and June 2020, the experiences of younger adult stroke survivors aged 18 to 45 at the time of the stroke were collected. Data were gathered from publicly available sources, including social media, and from English-speaking users. In total, 117 accounts from 103 participants were identified from films, autobiographical books, blogs, websites, videos, Twitter and Instagram. Data analysis followed narrative and multimodal analysis with a focus on rehabilitation needs.

RESULTS

Younger adult stroke survivors make sense of their experience by reflecting on how stroke has impacted their lives. Accounts reflected an emotional journey between the past self, the present self and evolving self, as well as associated challenges such as the impact on relationships and careers. The majority of accounts presented transitions as problematic, including the receipt of the initial diagnosis, or sometimes misdiagnosis, to returning home and achieving long-term rehabilitation goals. Specialist stroke nurses were considered essential in the rehabilitation process.

CONCLUSION

A complex process of recovery follows stroke for younger adult stroke populations. Challenges to the rehabilitation process need to be better understood and the role of nursing highlighted in future service provision. A series of age-related challenges were highlighted that require attention to improve the care and support offered.

IMPACT

This article informs clinicians, educators, and policymakers of the age-related needs of young adult stroke survivors. Focusing on the individual and the development of age-appropriate person-centred stroke care is important. The study highlights the role of stroke nursing and challenges the current policy focus on older stroke populations as well as arguing for greater awareness of age-appropriate stroke rehabilitation in younger adults following stroke.

Establishing the effectiveness of technology-enabled dementia education for health and social care practitioners: a systematic review

BACKGROUND

Dementia prevalence is increasing globally and yet evidence suggest that gaps exist in dementia-specific knowledge among health and social care practitioners. Technological modes of educational delivery may be as effective as traditional education and can provide practitioners with increased accessibility to dementia training. Benefits of digitally based dementia education have been established including pedagogical strategies that influence dementia knowledge and care attitudes. This review aimed to appraise and synthesise contemporary experimental evidence that evaluated technology-enabled dementia education for health and social care practitioners. Outcomes based on Kirkpatrick's Model were learner satisfaction; knowledge, skills, and attitudes; behaviours; and results.

METHODS

MEDLINE, CINAHL, and Web of Science were among 8 bibliographic databases searched from January 2005 until February 2020. Keywords included dementia and education (and terms for technological modes of education, learning, or training). We included experimental and quasi-experimental studies. Medical Education Research Study Quality Instrument established the overall quality of included studies and pragmatic application of Mixed Methods Appraisal Tool established individual study quality and highlighted methodological features of educational research. Narrative synthesis was conducted as heterogeneous outcome data precluded meta-analysis.

RESULTS

We identified 21 relevant studies: 16 evaluated online dementia education and 5 evaluated computer-based approaches. Most studies used before-after designs and study quality was moderate overall. Most studies reported knowledge-based outcomes with statistically significant findings favouring the training interventions. Positive effects were also observed in studies measuring skills and attitudinal change. Fewer studies reported significant findings for behavioural change and results due to training. Case-based instruction was a frequently described instructional strategy in online dementia education and videos were common information delivery modes. CD-ROM training and simulation activities were described in computer-based dementia education.

DISCUSSION

Future emphasis must be placed on teaching and learning methods within technology-enabled dementia education which should be role relevant and incorporate active and interactive learning strategies. Future evaluations will require contextually relevant research methodologies with capacity to address challenges presented by these complex educational programmes and multi-component characteristics.

Acute fasciolosis in an alpaca: a case report

Background

The popularity of new world camelids, particularly alpacas, is growing rapidly in Ireland, presenting a clinical challenge to veterinary practitioners who may not have worked with these species previously. To the authors’ knowledge, the clinical course of a case of acute fasciolosis in an alpaca has not previously been reported, and fasciolosis has not been reported at all in alpacas in Ireland, making this case report a valuable addition to the current literature.

Case presentation

A three-year-old male castrated huacaya alpaca was admitted to UCD Veterinary Hospital with a two-day history of colic and tenesmus. He had been treated with albendazole, dexamethasone and potentiated amoxycillin by the referring veterinary practitioner with no response. On initial clinical exam, sensitivity to abdominal palpation was the only abnormality. However, the alpaca proceeded to show abnormal lying positions, tenesmus and reduced faecal output over the next 24 h. A general blood panel demonstrated moderate anaemia, marked hyperglobulinaemia and moderately increased hepatocellular and hepatobiliary enzyme activity. Abdominal radiography revealed enlargement of the first forestomach compartment without evidence of gastrointestinal obstruction or peritonitis. An abdominal ultrasound exam revealed an elongated, heterogenous mass in the caudoventral abdomen that appeared to be contiguous with the liver. FNA of this mass revealed that it was in fact a liver lobe with biliary stasis and inflammation. Faecal sedimentation demonstrated Fasciola hepatica eggs. In spite of treatment with triclabendazole and supportive treatment including blood transfusion, the alpaca’s condition continued to deteriorate and he was euthanised. On post-mortem exam, acute fasciolosis was diagnosed.

Conclusions

The clinical presentation and course of a case of acute fasciolosis in an individual alpaca is described, including the results of a range of diagnostic tests that were carried out. The final diagnosis is supported by a description of post-mortem findings. This information will serve as a resource for veterinary practitioners involved in the diagnosis and treatment of similar cases.

Designing and developing core physiology learning outcomes for pre-registration nursing education curriculum

Physiology is a key element of "bioscience" education within pre-registration nursing programs, but there is a lack of clarity on what is included. Physiology and bioscience content and delivery are highly varied across both higher education institutions and the related programs in the United Kingdom (UK). Despite evidence highlighting concerns over nurses' lack of bioscience knowledge and unsafe practice, there is no universally agreed on curriculum with detailed outcomes of minimum levels of knowledge to support nurses in practice and patient care. This study aimed to inform the construction of discipline-specific physiology learning outcomes to clarify relevant physiological topics required in pre-registration nursing. Initially, 360 learning outcomes were identified from various sources. Using a modified Delphi approach, an expert panel from the Bioscience in Nurse Education group reviewed and modified the list to 195 proposed outcomes. These were circulated to universities in the UK who teach nursing (n = 65). Outcomes that had 80% consensus were automatically included in the next round, with others recommended with modification (response rate 22%). The panel reviewed the modifications, and 182 outcomes were circulated in the second questionnaire (response rate 23%), and further panel review resulting in 177 outcomes agreed. These learning outcomes do not suggest how they should be delivered, but gives the basic level required for qualification as a nurse commensurate with the Nursing and Midwifery Council new standards for the "future nurse."

Increasing cardiovascular medication adherence: A medical research council complex mhealth intervention mixed-methods feasibility study to inform global practice

AIMS

To evaluate a mHealth intervention to increase medication adherence among Iranian coronary heart disease patients.

DESIGN

Quantitative-dominant mixed-methods study.

DATA SOURCE

Iranian coronary heart disease patients' responses and most recent clinical documents as well as responses from Iranian cardiac nurses who participated in this study.

METHODS

The study was conducted between September 2015-April 2016 drawing on the Medical Research Council's Framework. Phase one comprised of a patients' survey and focus groups with cardiac nurses. The automated short message service reminder was piloted in phase two. We recruited 78 patients and randomized to receive either 12-week daily reminders or usual care. The primary outcome was the effect on medication adherence; secondary outcomes were self-efficacy, ejection fraction, functional capacity, readmission rate and quality of life.

RESULTS

Feasibility was evidenced by high ownership of mobile phones and high interest in receiving reminders. Participants in the intervention group showed significantly higher medication adherence compared with the control group.

CONCLUSION

The mHealth intervention was well accepted and feasible with early evidence of effectiveness that needs to be confirmed in a fully powered future randomized clinical trial.

Enhanced Recovery After Surgery (ERAS) Reduces Hospital Costs and Improve Clinical Outcomes in Liver Surgery: a Systematic Review and Meta-Analysis

BACKGROUND

Enhanced recovery after surgery (ERAS) protocols are evidence-based, multimodal and patient-centred approach to optimize patient care and experience during their perioperative pathway. It has been shown to be effective in reducing length of hospital stay and improving clinical outcomes. However, evidence on its effective in liver surgery remains weak. The aim of this review is to investigate clinical benefits, cost-effectiveness and compliance to ERAS protocols in liver surgery.

METHODS

A systematic literature search was conducted using CINAHL Plus, EMBASE, MEDLINE, PubMed and Cochrane for randomized control trials (RCTs) and cohort studies published between 2008 and 2019, comparing effect of ERAS protocols and standard care on hospital cost, LOS, complications, readmission, mortality and compliance.

RESULTS

The search resulted in 6 RCTs and 21 cohort studies of 3739 patients (1777 in ERAS and 1962 in standard care group). LOS was reduced by 2.22 days in ERAS group (MD = -2.22; CI, -2.77 to -1.68; p < 0.00001) compared to the standard care group. Fewer patients in ERAS group experienced complications (RR, 0.71; 95% CI, 0.65-0.77; p = < 0.00001). Hospital cost was significantly lower in the ERAS group (SMD = -0.98; CI, -1.37 to - 0.58; p < 0.0001).

CONCLUSION

Our review concluded that the introduction of ERAS protocols is safe and feasible in hepatectomies, without increasing mortality and readmission rates, whilst reducing LOS and risk of complications, and with a significant hospital cost savings. Laparoscopic approach may be necessary to reduce complication rates in liver surgery. However, further studies are needed to investigate overall compliance to ERAS protocols and its impact on clinical outcomes.

P11.49 An electrophysiological signature of glioma infiltration in the ex vivo human brain

BACKGROUND

Invading glioma cells affect the physiological function of the peritumoural cortex. This may manifest clinically as seizures. Here, we investigate the effect the invading glioma cells on the electrophysiological signalling of the peritumoral cortex using living human brain tissue donated by people having a craniotomy for glioma resection (REC approval, 18/SW/002).

MATERIAL AND METHODS

The brain tissue was cut into thin slices, which preserved the architecture of the glioma and the adjacent healthy brain. The brain slices were incubated in 5-aminolevulinic acid to make the glioma cells fluorescent. We observed 5-ALA induced fluorescence in both low-grade and high-grade gliomas. This enabled us to make electrophysiological recordings of brain activity across the boundary between glioma and brain.

RESULTS

We recorded from brain slices of 5 participants with glioblastoma and 4 participants with oligodendroglioma (WHO grade II - III). Spontaneous “seizure-like” discharges were recorded in brain slices from 5/8 participants (3 GBM, 2 oligodendroglioma) who reported seizures and from one participant (GBM) who had not had any clinical seizures. Further analysis of the electrical discharges revealed that they could be subdivided into two distinct types based on the major frequencies in the discharge.

CONCLUSION

We concluded that human brain slices from people with either a low-grade or a high-grade glioma can generate spontaneous seizure-like discharges. This electrophysiological signature will be compared to infiltration and grade of the glioma cells in the donated sample. The living human brain tissue preparation gives us a platform to study the mechanisms of tumour-associated seizures and how abnormal neural activity affects glioma growth.

Development of a perceived exertion scale for dogs using selected physiologic parameters

OBJECTIVE

To develop a perceived exertion scale for dogs exercising on a treadmill and to assess intra- and inter-observer variability.

MATERIALS AND METHODS

Fifteen healthy client-owned dogs participated in paired exercise trials. Measurements of lactate, glucose, heart rate, temperature, respiratory rate and regional tissue oximetry were obtained before, during and after exercise. Perceived exertion scale scores were recorded during exercise and using video recordings to evaluate inter-observer variability. Correlations were evaluated using the Spearman's non-parametric method.

RESULTS

Thirteen dogs completed both trials. Dogs walked or trotted on the treadmill with an average perceived exertion score of 2 in both trials. Holter heart rate was positively correlated with perceived exertion scale scores from all observers for both trials. In trial 1, plasma glucose decreased in association with increase in perceived exertion and, in trial 2, cutaneous oximetry decreased, respiratory rate increased and temperature increased with increases on the perceived exertion scale. Inter-observer perceived exertion scale scores were positively correlated in both trials. There was no intra-observer variability between trials.

CLINICAL SIGNIFICANCE

The perceived exertion scale correlated with the measured physiologic parameters in dogs exercising at mild to moderate intensity. The perceived exertion scale was consistent and repeatable but larger study numbers and further validation are needed before it can be widely applied.

The Anatomical Society's core anatomy syllabus for undergraduate nursing

The Anatomical Society has developed a series of learning outcomes in consultation with nursing educators delivering anatomical content to undergraduate (preregistration) nursing students. A Delphi panel methodology was adopted to select experts within the field that would recommend core anatomical content in undergraduate nursing programmes throughout the UK. Using the Anatomical Society's Core Gross Anatomy Syllabus for Medical Students as a foundation, a modified Delphi technique was used to develop discipline-specific outcomes to nursing graduates. The Delphi panel consisted of 48 individuals (n = 48) with a minimum of 3 years' experience teaching anatomy to nursing students, representing a broad spectrum of UK Higher Education Institutions. The output from this study was 64 nursing specific learning outcomes in anatomy that are applicable to all undergraduate (preregistration) programmes in the UK. The new core anatomy syllabus for Undergraduate Nursing offers a basic anatomical framework upon which nurse educators, clinical mentors and nursing students can underpin their clinical practice and knowledge. The learning outcomes presented may be used to develop anatomy teaching within an integrated nursing curriculum.

The Role of the Occupational Therapist in Addressing the Spiritual Needs of Clients

There is a continuing debate within the health professions on the place of spirituality and the approach to be taken towards spiritual needs within holistic care. In occupational therapy, the need for both a working definition of spirituality and evidence to validate spirituality as a performance component has been identified (Urbanowski and Vargo 1994). The aim of this study was to add to the debate by exploring the experiences of occupational therapists who have encountered spiritual needs in their practice.

A phenomenological approach using semi-structured interviews with three Christian occupational therapists explored their understanding of spirituality and experience of spiritual needs in practice. While the therapists interviewed had some difficulty in putting into words the concept of spirituality, they were able to identify spiritual needs in their clients and expressed opinions regarding the possible role of the occupational therapist in dealing with the spiritual needs of clients. It was clear that spiritual counselling was not considered to be appropriate for the occupational therapist, although recognising the spiritual dimension of an individual was important.

In the United Kingdom, the occupational therapy profession needs to develop further its view on spirituality in holistic care and the impact that it has on the health and wellbeing of its clients.

An Exploration of Comfort and Discomfort Amongst Children and Young People with Intellectual Disabilities Who Depend on Postural Management Equipment

BACKGROUND

The natural response to the intrusive bodily sensation is positional change. This study explored how children and young people (CYP) with intellectual disabilities had their comfort needs met when using adaptive positioning equipment.

METHODS

Thirteen qualitative case studies were undertaken. A parent, a teacher/key worker and a therapist for each CYP were interviewed, and daily routines were observed, with selective video recording. Single case and cross case analyses were undertaken.

RESULTS

Attentive caregivers read the behavioural expressions of the CYP and responded reassuringly, safeguarding them from discomforting experiences. Threats to comfort include the restrictive nature of some equipment accessories, positioning errors and procedural stretching.

CONCLUSIONS

The same item of equipment can be both comfortable and uncomfortable. Given the social and interactional world in which the CYP live and learn, it is others who must accept responsibility for ensuring their optimal level of comfort.

Post-operative 3-dimensional contrast-enhanced ultrasound (CEUS) versus Tc99m-DTPA in the detection of post-surgical perfusion defects in kidney transplants - preliminary findings

PURPOSE

2800 renal transplants are carried out annually in the UK and it is standard practice to perform a Tc-DTPA renogram examination after surgery to check perfusion. This provides some functional information but suffers from low spatial resolution, is lengthy, immobile and costly and uses ionizing radiation. We surmised that contrast-enhanced ultrasound (CEUS) would provide an accurate alternative with increased speed, resolution (temporal and spatial), cost efficiency and safety.

MATERIALS AND METHODS

97 renal transplant patients underwent both Tc-DTPA and CEUS after surgery to assess the perfusion of the graft. Tc-DTPA was performed in the nuclear medicine department with at least 10 minutes of continuous screening and a standard dose of 150 mBq Tc-DTPA. CEUS consisted of I. V. 2.4 ml Sonovue contrast agent, 60 seconds continuous capture and a 3 D acquisition of the organ. 3 D CEUS was assessed using QLab analysis software.

RESULTS

Tc-DTPA detected 9 perfusion defects of varying size. CEUS detected all these defects plus 14 further defects (0.2 - 17 % of total renal volume) not detected on DTPA. These results demonstrate a statistically significant divergence (p < 0.0001). Retrospective clinical correlation showed ligated polar arteries in 8 of these 14 cases.

CONCLUSION

CEUS will detect perfusion defects seen with Tc-DTPA and due to increased spatial and temporal resolution and multiple scanning angles, will detect further perfusion defects not seen on Tc-DTPA. 3 D CEUS is useful in the quantification of perfusion defects. CEUS is an accurate examination for detecting renal transplant perfusion defects and will detect significantly more defects than DTPA.

Telephone management of severe wasp stings in rural Nepal: a case report

We describe a young woman from a rural village in Nepal who suffered multiple wasp and hornet stings. She collapsed and was managed by a telephone consultation between a village health worker and a hospital specialist. The patient recovered fully. Not only was the telephone consultation efficient in terms of cost savings from avoided hospital treatment, but it was also effective since, with conventional care, there was a strong possibility that the patient would have died on her way to hospital. This case illustrates the potential for telephone-delivered rural care and management in emergency situations.

The supervision of professional doctorates: experiences of the processes and ways forward

The doctoral research terrain is changing, as new-styles, for example professional doctorates, are being developed (Park, C., 2005. New variant PhDL the changing nature of the doctorate in the UK. Journal of Higher Education Policy and Management 27(2), 189-207). There is a scarcity of literature aimed at supervisors (Gatfield, T., 2005, An investigation into PhD supervisory management styles: development of a dynamic conceptual model and its managerial implications. Journal of Higher Education Policy and Management 27(3), 311-325) and this is particularly so in relation to professional doctorates. In this position paper we argue that the supervisory approach required for a professional doctorate student is different than that required for a PhD. Professional doctorate students, like PhD students, are required to make an explicit contribution to knowledge. Their emphasis, however, needs to be in producing knowledge that is theoretically sound, original, and of relevance to their practice area. This is of increasing importance within healthcare with the growing emphasis on patient driven translational research. As such, the students and their supervisors face unique challenges of balancing academic requirements with praxis. We suggest this requires specific tools to make explicit the dialogical relationship between a particular project and the cultural, social, educational and political aspects of its environment. We expose the potential of soft systems methodology as a means to highlight the emergent aspects of a doctoral practice development project, their respective and evolving supervisory interactions. This focus of this paper is therefore not about guiding supervision in a managerial sense, but rather at offering methodological suggestions that could underpin applied research at doctoral level.

Preconception counseling in women with diabetes: a population-based study in the north of England

OBJECTIVE To investigate the association of preconception counseling with markers of care and maternal characteristics in women with pregestational diabetes. RESEARCH DESIGN AND METHODS The study includes data from a regional multi-center survey on 588 women with pregestational diabetes who delivered a singleton pregnancy between 2001 and 2004. Logistic regression was used to obtain crude and adjusted estimates of association. RESULTS Preconception counseling was associated with better glycemic control 3 months preconception (odds ratio 1.91, 95% CI 1.10-3.04) and in the first trimester (2.05, 1.39-3.03), higher preconception folic acid intake (4.88, 3.26-7.30), and reduced risk of adverse pregnancy outcome (P = 0.027). Uptake of preconception counseling was positively associated with type 1 diabetes (1.87, 1.14-3.07) and White British ethnicity (2.56, 1.17-5.6) and negatively with deprivation score (0.78, 0.70-0.87). CONCLUSIONS Efforts are needed to improve preconception counseling rates. Uptake is associated with maternal sociodemographic characteristics.

Enhanced relapse prevention for bipolar disorder by community mental health teams: cluster feasibility randomised trial

BACKGROUND

Relapse prevention for bipolar disorder increases time to relapse but is not available in routine practice.

AIMS

To determine the feasibility and effectiveness of training community mental health teams (CMHTs) to deliver enhanced relapse prevention.

METHOD

In a cluster randomised controlled trial, CMHT workers were allocated to receive 12 h training in enhanced relapse prevention to offer to people with bipolar disorder or to continue giving treatment as usual. The primary outcome was time to relapse and the secondary outcome was functioning.

RESULTS

Twenty-three CMHTs and 96 service users took part. Compared with treatment as usual, enhanced relapse prevention increased median time to the next bipolar episode by 8.5 weeks (hazard ratio 0.79, 95% CI 0.45-1.38). Social and occupational functioning improved with the intervention (regression coefficient 0.68, 95% CI 0.05-1.32). The clustering effect was negligible but imprecise (intracluster correlation coefficient 0.0001, 95% CI 0.0000-0.5142).

CONCLUSIONS

Training care coordinators to offer enhanced relapse prevention for bipolar disorder may be a feasible effective treatment. Large-scale cluster trials are needed.

Sub-optimal hand sanitiser usage in a hospital entrance during an influenza pandemic, New Zealand, August 2009

The hand hygiene behaviours of the public in response to the current H1N1 influenza pandemic 2009 (or other pandemics) have not previously been described. An observational study was undertaken to examine hand hygiene behaviours by people passing a hand sanitiser station in the foyer of a public hospital in New Zealand in August 2009. Of the 2,941 subjects observed, 449 (18.0%, 95% confidence interval: 16.6, 19.6) used the hand sanitiser. This is a far from optimal result in response to the health promotion initiatives in the setting of a pandemic. These findings suggest the need for more effective health promotion of hand hygiene and also provide baseline measurements for future evaluation of hygiene practices.

An exploration of German and British physiotherapists' views on the effects of hippotherapy and their measurement

Hippotherapy (Greek hippos = horse) is a specialised physiotherapy treatment that makes use of the horses' unique three-dimensional movement impulses at a walk to facilitate movement responses in patients sitting on the horse's back (Strauss, 2000). Despite a substantial body of anecdotal and clinical evidence for its benefits, research evidence for hippotherapy is sparse. This questionnaire survey was the first study in a series of investigations exploring the views of physiotherapists and people with cerebral palsy who use hippotherapy. These investigations, in turn, form the basis from which the authors will recommend outcome measures for individuals with cerebral palsy in a hippotherapy environment. This study aimed to: (a) establish the pattern of hippotherapy practice in Germany and the U.K.; (b) examine the perceived main effects of hippotherapy on people with cerebral palsy in Germany and the U.K.; and (c) investigate how these effects are being measured in both countries. The results highlighted considerable differences in how hippotherapy is practised in the U.K. compared with in Germany. In spite of this, the study revealed agreement among respondents on the overall perceived effects of hippotherapy on individuals with cerebral palsy, namely, the regulation of muscle tone, improvement of postural control and psychological benefits. The results also indicate scant use of outcome measures to evaluate these effects. The impact of these findings is discussed in the light of published research, and suggestions for further research are made.

Mapping patients' experiences from initial change in health to cancer diagnosis: a qualitative exploration of patient and system factors mediating this process

Delays in the diagnosis of cancer are common, and they are attributed to both patient and healthcare system factors. Minimizing such delays and improving early detection rates is a key goal of the new cancer reform strategy in England, in light of recent data showing that survival rates in the UK are low. The aim of this study was to explore the pathway from initial persistent change in health to diagnosis of cancer in a sample of patients from seven diagnostic groups in the UK and the factors mediating this process. Qualitative interviews with patients diagnosed with cancer were carried out. Seventy-five cancer patients discussed their pre-diagnosis experience as part of a broader exploration of their symptom experience for a larger study. Data were analysed by using content analysis and chart events. A broader range of mediating factors affecting and extending the patient pathway to diagnosis were reported in relation to lung, gastrointestinal and head and neck cancers and lymphoma, compared with breast, gynaecological and brain cancer patients. Many of the mediating factors were patient-related (e.g. misattribution of symptoms to common ailments, underestimation of the seriousness of the symptoms, self-medication or monitoring of symptoms, etc.). Primary care practitioner-factors were also prominent, including the exploration of firstly more common possibilities for treating the presenting symptoms without follow-up of persisting symptoms. Public health education about common cancer signs and symptoms, educational approaches in primary care to improve early diagnoses of cancer and updated guidelines for referral of suspected cancers should be enhanced before we can see any improvements in survival rates from cancer in the UK.

Isospin symmetry of odd-odd mirror nuclei: identification of excited states in N=Z-2 48Mn

Excited states have been observed in the N=Z-2 odd-odd nucleus 48Mn for the first time. Through comparison with the structure of 48V, a first high-spin study of an odd-odd mirror pair has been achieved. Differences between the T=1 analogue states in this pair have been interpreted in terms of Coulomb effects, with the aid of shell-model calculations in the full pf valence space. Unlike other mirror pairs, the energy differences have been interpreted almost entirely as due to a monopole effect associated with smooth changes in radius (or deformation) as a function of angular momentum. In addition, the large energy shift between analogue negative-parity states is interpreted in terms of the electromagnetic spin-orbit interaction in nuclei.

Effective charges in the fp shell

Following the heavy-ion fusion-evaporation reaction 32S+24Mg at 95 MeV beam energy the lifetimes of analogue states in the T(z)=+/-1/2 A=51 mirror nuclei 51Fe and 51Mn have been measured using the Cologne plunger device coupled to the GASP gamma-ray spectrometer. The deduced B(E2;27/2(-)-->23/2(-)) values afford a unique opportunity to probe isoscalar and isovector polarization charges and to derive effective proton and neutron charges, epsilon(p) and epsilon(n), in the fp shell. A comparison between the experimental results and several different large-scale shell-model calculations yields epsilon(p) approximately 1.15e and epsilon(n) approximately 0.80e.

VNS in patients with previous unsuccessful resective epilepsy surgery: antiepileptic and psychotropic effects

OBJECTIVES

To assess the efficacy of vagus nerve stimulation (VNS) in patients with medically and surgically intractable complex partial seizures (CPS).

PATIENTS AND METHODS

Sixteen patients with previous temporal [15] and frontal [one] resections were treated with VNS between 1994 and 1999 at King's College Hospital, London, UK. Post-operative video-electroencephalogram telemetry had shown that CPS started from the operated side in 12 patients, contralaterally in three and bilaterally independently in one.

RESULTS

Three patients (18.75%) had 50% or more reduction in seizure frequency, but one showed severe worsening of epilepsy, which remitted upon VNS discontinuation. The antiepileptic effect of VNS was not different with respect to the type of operation (anterior temporal lobectomy vs amygdalohippocampectomy), the side of operation, or the side of seizure onset. We observed psychotropic effects in two patients with post-ictal psychosis, in two others with depression, and in a child with severe behavioral disorder.

CONCLUSIONS

VNS may have a rather limited antiepileptic role to play in patients with persistent seizures following epilepsy surgery, but may independently possess useful antipsychotic and mood-stabilizing properties.

Survival in Duchenne muscular dystrophy: improvements in life expectancy since 1967 and the impact of home nocturnal ventilation

We reviewed the notes of 197 patients with Duchenne muscular dystrophy whose treatment was managed at the Newcastle muscle centre from 1967 to 2002, to determine whether survival has improved over the decades and whether the impact of nocturnal ventilation altered the pattern of survival. Patients were grouped according to the decade of death and whether or not they were ventilated. Kaplan Meier survival analyses showed significant decade on decade improvement in survival. Mean age of death in the 1960s was 14.4 years, whereas for those ventilated since 1990 it was 25.3 years. Cardiomyopathy significantly shortened life expectancy from 19 years to a mean age of 16.9 years. Better coordinated care probably improved the chances of survival to 25 years from 0% in the 1960s to 4% in the 1970s and 12% in the 1980s, but the impact of nocturnal ventilation has further improved this chance to 53% for those ventilated since 1990.

Idiopathic intracranial hypertension: is papilloedema inevitable?

Headaches and papilloedema are key features of idiopathic (benign) intracranial hypertension (IIH). We describe three children in whom IIH was diagnosed in the absence of papilloedema. Recognition of atypical cases of IIH is important because pressure lowering treatment may be effective.

Measured ambulation and self-reported health status following total joint replacement for the osteoarthritic knee

OBJECTIVE

To quantify the increase in ambulation produced by total knee replacement for osteoarthritis (OA) of the knee and to compare this with questionnaire-derived data.

METHODS

We compared the measured ambulatory activity and self-reported Nottingham Health Profile (NHP) data of 19 subjects with OA of the knee before and after total knee replacement (TKR).

RESULTS

Subjects were considerably restricted in their measured activity before operation compared with subjects with less severe disease. At 6 months the activity had increased by an average of 79% (P=0.02). The pain scale of the NHP had significantly improved at 3 months, as had the mobility scale. Between 3 and 6 months, however, at the same time the measured activity was increasing, self-reported mobility declined.

CONCLUSIONS

Replacement of a knee for OA is an effective way of improving ambulation. At 6 months the average increase amounted to 79%. Self-reported mobility did not correlate with mobility measured objectively.

Resection of the lesion in patients with hypothalamic hamartomas and catastrophic epilepsy

BACKGROUND

Patients with hypothalamic hamartomas (HH) often have severe refractory epilepsy, incapacitating behavioral abnormalities, and cognitive decline. Attempts to control the seizure disorder by resection of apparently epileptogenic mesial temporal or other cortical structures have failed consistently.

OBJECTIVE

To report a series of 13 patients in whom the hamartoma itself was resected.

METHODS

All patients underwent preoperative evaluation between ages 2 and 33 years and had subtotal or complete resection of the hamartoma. Follow-up ranged from 1 to 5.5 years (mean: 2.8 y).

RESULTS

Preoperatively, all patients had variable combinations of gelastic, complex partial, and generalized seizures. Eight had drop attacks. In addition, all had marked behavior abnormalities and cognitive impairment. Postoperatively, two patients are completely seizure-free and 11 are either seizure-free or have achieved a greater than 90% reduction of drop attacks and generalized tonic-clonic seizures. However, minor gelastic, complex partial, and atypical absence seizures have persisted in 11 patients, although at significantly reduced rates. In addition, there has been a dramatic improvement in behavior and cognition. Three patients had an anterior thalamic and one a capsular infarct, which left only minimal long-term deficits. Exact location of the lesion in relation to the interpeduncular fossa and the walls of the third ventricle correlated with extent of excision, seizure control, and complication rate.

CONCLUSION

Resection can alleviate both the seizures and the behavioral and cognitive abnormalities of hypothalamic hamartomas, but complications are frequent.

Preoperative and early postoperative magnetic resonance imaging in two cases of childhood choroid plexus carcinoma

We present and illustrate the MRI appearances of two children with choroid plexus carcinoma. The MRI characteristics of these rare tumours are reviewed. Since total surgical resection is a significant prognostic factor, early postoperative MRI was performed in both cases to ensure surgical clearance. In one case a complete resection was documented and this patient remains well at short-term follow-up. Residual tumour was noted in the second case, but despite "second look" surgery there was subsequent local relapse.

Congenital midline cleft of the posterior arch of atlas: a rare cause of symptomatic cervical canal stenosis

Developmental symptomatic C1 canal stenosis is very rare. We describe the computed tomography (CT) and magnetic resonance imaging (MRI) appearances in a 8-year-old child who presented with progressive upper and lower limb neurological symptoms and in whom imaging revealed the medial posterior hemiarches of a bifid C1 to be inturned and compressing the cervical cord. This particular configuration of the posterior arch of atlas is frequently associated with other craniocervical bony anomalies and presents with neurological symptoms early in life. Early CT or MRI examination of patients with symptomatic posterior arch of C1 defects is necessary, in order to detect such an appearance, since surgical treatment may prevent neurological deterioration.

Coulomb energy differences in t = 1 mirror rotational bands in (50)Fe and (50)Cr

Gamma rays from the N = Z-2 nucleus (50)Fe have been observed, establishing the rotational ground state band up to the state J(pi) = 11+ at 6.994 MeV excitation energy. The experimental Coulomb energy differences, obtained by comparison with the isobaric analog states in its mirror (50)Cr, confirm the qualitative interpretation of the backbending patterns in terms of successive alignments of proton and neutron pairs. A quantitative agreement with experiment has been achieved by exact shell model calculations, incorporating the differences in radii along the yrast bands, and properly renormalizing the Coulomb matrix elements in the pf model space.
