MRI monitoring of macaque monkeys in neuroscience: Case studies, resource and normative data comparisons.

Information from Magnetic Resonance Imaging (MRI) is useful for diagnosis and treatment management of human neurological patients. MRI monitoring might also prove useful for non-human animals involved in neuroscience research provided that MRI is available and feasible and that there are no MRI contra-indications precluding scanning. However, MRI monitoring is not established in macaques and a resource is urgently needed that could grow with scientific community contributions. Here we show the utility and potential benefits of MRI-based monitoring in a few diverse cases with macaque monkeys. We also establish a PRIMatE MRI Monitoring (PRIME-MRM) resource within the PRIMatE Data Exchange (PRIME-DE) and quantitatively compare the cases to normative information drawn from MRI data from typical macaques in PRIME-DE. In the cases, the monkeys presented with no or mild/moderate clinical signs, were well otherwise and MRI scanning did not present a significant increase in welfare impact. Therefore, they were identified as suitable candidates for clinical investigation, MRI-based monitoring and treatment. For each case, we show MRI quantification of internal controls in relation to treatment steps and comparisons with normative data in typical monkeys drawn from PRIME-DE. We found that MRI assists in precise and early diagnosis of cerebral events and can be useful for visualising, treating and quantifying treatment response. The scientific community could now grow the PRIME-MRM resource with other cases and larger samples to further assess and increase the evidence base on the benefits of MRI monitoring of primates, complementing the animals' clinical monitoring and treatment regime.

Aspirin and other non-steroidal anti-inflammatory drugs for the prevention of dementia.

BACKGROUND: Dementia is a worldwide concern. Its global prevalence is increasing. At present, there is no medication licensed to prevent or delay the onset of dementia. Inflammation has been suggested as a key factor in dementia pathogenesis. Therefore, medications with anti-inflammatory properties could be beneficial for dementia prevention. OBJECTIVES: To evaluate the effectiveness and adverse effects of aspirin and other non-steroidal anti-inflammatory drugs (NSAIDs) for the primary or secondary prevention of dementia. SEARCH METHODS: We searched ALOIS, the specialised register of the Cochrane Dementia and Cognitive Improvement Group up to 9 January 2020. ALOIS contains records of clinical trials identified from monthly searches of several major healthcare databases, trial registries and grey literature sources. We ran additional searches across MEDLINE (OvidSP), Embase (OvidSP) and six other databases to ensure that the searches were as comprehensive and up-to-date as possible. We also reviewed citations of reference lists of included studies. SELECTION CRITERIA: We searched for randomised controlled trials (RCTs) and controlled clinical trials (CCTs) comparing aspirin or other NSAIDs with placebo for the primary or secondary prevention of dementia. We included trials with cognitively healthy participants (primary prevention) or participants with mild cognitive impairment (MCI) or cognitive complaints (secondary prevention). DATA COLLECTION AND ANALYSIS: We used standard methodological procedures according to the Cochrane Handbook for Systematic Reviews of Interventions. We rated the strength of evidence for each outcome using the GRADE approach. MAIN RESULTS: We included four RCTs with 23,187 participants. Because of the diversity of these trials, we did not combine data to give summary estimates, but presented a narrative description of the evidence. We identified one trial (19,114 participants) comparing low-dose aspirin (100 mg once daily) to placebo. Participants were aged 70 years or older with no history of dementia, cardiovascular disease or physical disability. Interim analysis indicated no significant treatment effect and the trial was terminated slightly early after a median of 4.7 years' follow-up. There was no evidence of a difference in incidence of dementia between aspirin and placebo groups (risk ratio (RR) 0.98, 95% CI 0.83 to 1.15; high-certainty evidence). Participants allocated aspirin had higher rates of major bleeding (RR 1.37, 95% CI 1.17 to 1.60, high-certainty evidence) and slightly higher mortality (RR 1.14, 95% CI 1.01 to 1.28; high-certainty evidence). There was no evidence of a difference in activities of daily living between groups (RR 0.84, 95% CI 0.70 to 1.02; high-certainty evidence). We identified three trials comparing non-aspirin NSAIDs to placebo. All three trials were terminated early due to adverse events associated with NSAIDs reported in other trials. One trial (2528 participants) investigated the cyclo-oxygenase-2 (COX-2) inhibitor celecoxib (200 mg twice daily) and the non-selective NSAID naproxen (220 mg twice daily) for preventing dementia in cognitively healthy older adults with a family history of Alzheimer's disease (AD). Median follow-up was 734 days. Combining both NSAID treatment arms, there was no evidence of a difference in the incidence of AD between participants allocated NSAIDs and those allocated placebo (RR 1.91, 95% CI 0.89 to 4.10; moderate-certainty evidence). There was also no evidence of a difference in rates of myocardial infarction (RR 1.21, 95% CI 0.61 to 2.40), stroke (RR 1.82, 95% CI 0.76 to 4.37) or mortality (RR 1.37, 95% CI 0.78 to 2.43) between treatment groups (all moderate-certainty evidence). One trial (88 participants) assessed the effectiveness of celecoxib (200 mg or 400 mg daily) in delaying cognitive decline in participants aged 40 to 81 years with mild age-related memory loss but normal memory performance scores. Mean duration of follow-up was 17.6 months in the celecoxib group and 18.1 months in the placebo group. There was no evidence of a difference between groups in test scores in any of six cognitive domains. Participants allocated celecoxib experienced more gastrointestinal adverse events than those allocated placebo (RR 2.66, 95% CI 1.05 to 6.75; low-certainty evidence). One trial (1457 participants) assessed the effectiveness of the COX-2 inhibitor rofecoxib (25 mg once daily) in delaying or preventing a diagnosis of AD in participants with MCI. Median duration of study participation was 115 weeks in the rofecoxib group and 130 weeks in the placebo group. There was a higher incidence of AD in the rofecoxib than the placebo group (RR 1.32, 95% CI 1.01 to 1.72; moderate-certainty evidence). There was no evidence of a difference between groups in cardiovascular adverse events (RR 1.07, 95% CI 0.68 to 1.66; moderate-certainty evidence) or mortality (RR 1.62, 95% CI 0.85 to 3.05; moderate-certainty evidence). Participants allocated rofecoxib had more upper gastrointestinal adverse events (RR 3.53, 95% CI 1.17 to 10.68; moderate-certainty evidence). Reported annual mean difference scores showed no evidence of a difference between groups in activities of daily living (year 1: no data available; year 2: 0.0, 95% CI -0.1 to 0.2; year 3: 0.1, 95% CI -0.1 to 0.3; year 4: 0.1, 95% CI -0.1 to 0.4; moderate-certainty evidence). AUTHORS' CONCLUSIONS: There is no evidence to support the use of low-dose aspirin or other NSAIDs of any class (celecoxib, rofecoxib or naproxen) for the prevention of dementia, but there was evidence of harm. Although there were limitations in the available evidence, it seems unlikely that there is any need for further trials of low-dose aspirin for dementia prevention. If future studies of NSAIDs for dementia prevention are planned, they will need to be cognisant of the safety concerns arising from the existing studies.

The Rhesus Monkey Hippocampus Critically Contributes to Scene Memory Retrieval, But Not New Learning.

Humans can recall a large number of memories years after the initial events. Patients with amnesia often have lesions to the hippocampus, but human lesions are imprecise, making it difficult to identify the anatomy underlying memory impairments. Rodent studies enable great precision in hippocampal manipulations, but not investigation of many interleaved memories. Thus it is not known how lesions restricted to the hippocampus affect the retrieval of multiple sequentially encoded memories. Furthermore, disagreement exists as to whether hippocampal inactivations lead to temporally graded or ungraded amnesia, which could be a consequence of differences between rodent and human studies. In the current study, rhesus monkeys of both sexes received either bilateral neurotoxic hippocampal lesions or remained unoperated controls and were tested on recognition and new learning of visual object-in-place scenes. Monkeys with hippocampal lesions were significantly impaired at remembering scenes that were encoded before the lesion. We did not observe any temporal gradient effect of the lesion on memory recognition, with recent and remote memories being equally affected by the lesion. Monkeys with hippocampal lesions showed no deficits in learning new scenes. Thus, the hippocampus, like other cortical regions, may be engaged in the acquisition and storage of new memories, but the role of the damaged hippocampus can be taken over by spared hippocampal tissue or extra-hippocampal regions following a lesion. These findings illustrate the utility of experimental paradigms for studying retrograde and anterograde amnesia that make use of the capacity of nonhuman primates to rapidly acquire many distinct visual memories.SIGNIFICANCE STATEMENT Recalling old memories, creating new memories, and the process by which memories transition from temporary to permanent storage all may rely on the hippocampus. Whether the hippocampus is necessary for encoding and retrieval of multiple related visual memories in primates is not known. Monkeys that learned many visual memory problems before precise lesions of the hippocampus were impaired at recalling those memories after hippocampal damage regardless of when the memories were formed, but could learn new memory problems at a normal rate. This suggests the hippocampus is normally vital for retrieval of complex visual memories regardless of their age, and also points to the importance of investigating mechanisms by which memories may be acquired in the presence of hippocampal damage.

From screening to synthesis: using nvivo to enhance transparency in qualitative evidence synthesis.

AIMS AND OBJECTIVES: To explore the experiences and perceptions of healthcare staff caring for people with dementia in the acute setting. This article focuses on the methodological process of conducting framework synthesis using nvivo for each stage of the review: screening, data extraction, synthesis and critical appraisal. BACKGROUND: Qualitative evidence synthesis brings together many research findings in a meaningful way that can be used to guide practice and policy development. For this purpose, synthesis must be conducted in a comprehensive and rigorous way. There has been previous discussion on how using nvivo can assist in enhancing and illustrate the rigorous processes involved. DESIGN: Qualitative framework synthesis. METHODS: Twelve documents, or research reports, based on nine studies, were included for synthesis. CONCLUSION: The benefits of using nvivo are outlined in terms of facilitating teams of researchers to systematically and rigorously synthesise findings. nvivo functions were used to conduct a sensitivity analysis. Some valuable lessons were learned, and these are presented to assist and guide researchers who wish to use similar methods in future. RELEVANCE TO CLINICAL PRACTICE: Ultimately, good qualitative evidence synthesis will provide practitioners and policymakers with significant information that will guide decision-making on many aspects of clinical practice. The example provided explored how people with dementia are cared for acute settings.

Sensitive Interviewing in Qualitative Research.

In this paper we focus on important considerations when planning and conducting qualitative interviews on sensitive topics. Drawing on experiences of conducting interviews with dementia caregivers, a framework of essential elements in qualitative interviewing was developed to emphasize study participants' needs while also providing guidance for researchers. Starting with a definition of sensitive research, the framework includes preparing for interviews, interacting with gatekeepers of vulnerable groups, planning for interview timing, and location, building relationships and conducting therapeutic interactions, protecting ethically vulnerable participants, and planning for disengagement. This framework has the potential to improve the effectiveness of sensitive interviewing with vulnerable groups. © 2016 Wiley Periodicals, Inc.

Psychosocial Intervention Use in Long-Stay Dementia Care: A Classic Grounded Theory.

The objective of this study was to develop a substantive grounded theory of staff psychosocial intervention use with residents with dementia in long-stay care. "Becoming a person again" emerged as the core category accounting for staffs' psychosocial intervention use within long-stay care. Interview data were collected from participants in nine Irish long-stay settings: 14 residents with dementia, 19 staff nurses, one clinical facilitator, seven nurse managers, 21 nursing assistants, and five relatives. Constant comparative method guided the data collection and analysis. The researcher's theoretical memos, based on unstructured observation, and applicable extant literature were also included as data. By identifying the mutuality of the participants' experiences, this classic grounded theory explains staff motivation toward psychosocial intervention use within long-stay care. It also explains how institutional factors interact with those personal factors that incline individuals toward psychosocial intervention use.

Long-term effects of single or multiple neonatal sevoflurane exposures on rat hippocampal ultrastructure.

BACKGROUND: Neonatal exposure to general anesthetics may pose significant neurocognitive risk. Human epidemiological studies demonstrate higher rates of learning disability among children with multiple, but not single, exposures to anesthesia. The authors employ a rat model to provide a histological correlate for these population-based observations. The authors examined long-term differences in hippocampal synaptic density, mitochondrial density, and dendritic spine morphology. METHODS: Twenty male rat pups (n = 5/condition) were exposed to 2.5% sevoflurane under one of four conditions: single 2-h exposure on postnatal day 7 (P7); single 6-h exposure on P7; repeated 2-h exposures on P7, P10, and P13 for a cumulative 6 h of general anesthetics; or control exposure to 30% oxygen on P7, P10, and P13. RESULTS: Repeated exposure to general anesthetics resulted in greater synaptic loss relative to a single 2-h exposure (P < 0.001). The magnitude of synaptic loss induced by three 2-h exposures (1.977 ± 0.040 µm [mean ± SEM]) was more profound than that of a single 6-h exposure (2.280 ± 0.045 µm, P = 0.022). Repeated exposures did not alter the distribution of postsynaptic density length, indicating a uniform pattern of loss across spine types. In contrast, mitochondrial toxicity was best predicted by the cumulative duration of exposure. Relative to control (0.595 ± 0.017), both repeated 2-h exposures (0.479 ± 0.015) and a single 6-h exposure (0.488 ± 0.013) were associated with equivalent reductions in the fraction of presynaptic terminals containing mitochondria (P < 0.001). CONCLUSION: This suggests a "threshold effect" for general anesthetic-induced neurotoxicity, whereby even brief exposures induce long-lasting alterations in neuronal circuitry and sensitize surviving synapses to subsequent loss.

Multiple Anesthetic Exposure in Infant Monkeys Alters Emotional Reactivity to an Acute Stressor.

BACKGROUND: Retrospective studies in humans have shown a higher prevalence of learning disabilities in children that received multiple exposures to general anesthesia before the age of 4 yr. Animal studies, primarily in rodents, have found that postnatal anesthetic exposure causes neurotoxicity and neurocognitive deficits in adulthood. The authors addressed the question of whether repeated postnatal anesthetic exposure was sufficient to cause long-term behavioral changes in a highly translationally relevant rhesus monkey model, allowing study of these variables against a background of protracted nervous system and behavioral development. METHODS: Rhesus monkeys of both sexes underwent either three 4-h exposures to sevoflurane anesthesia (anesthesia group n = 10) or brief maternal separations (control group n = 10) on postnatal day 6 to 10 that were repeated 14 and 28 days later. Monkeys remained with their mothers in large social groups at all times except for overnight observation after each anesthetic/control procedure. At 6 months of age, each monkey was tested on the human intruder paradigm, a common test for emotional reactivity in nonhuman primates. RESULTS: The frequency of anxiety-related behaviors was significantly higher in monkeys that were exposed to anesthesia as neonates as compared with controls: anesthesia 11.04 ± 1.68, controls 4.79 ± 0.77, mean ± SEM across all stimulus conditions. CONCLUSION: Increased emotional behavior in monkeys after anesthesia exposure in infancy may reflect long-term adverse effects of anesthesia.

Pulmonary rehabilitation for chronic obstructive pulmonary disease.

BACKGROUND: Widespread application of pulmonary rehabilitation (also known as respiratory rehabilitation) in chronic obstructive pulmonary disease (COPD) should be preceded by demonstrable improvements in function (health-related quality of life, functional and maximal exercise capacity) attributable to the programmes. This review updates the review reported in 2006. OBJECTIVES: To compare the effects of pulmonary rehabilitation versus usual care on health-related quality of life and functional and maximal exercise capacity in persons with COPD. SEARCH METHODS: We identified additional randomised controlled trials (RCTs) from the Cochrane Airways Group Specialised Register. Searches were current as of March 2014. SELECTION CRITERIA: We selected RCTs of pulmonary rehabilitation in patients with COPD in which health-related quality of life (HRQoL) and/or functional (FEC) or maximal (MEC) exercise capacity were measured. We defined 'pulmonary rehabilitation' as exercise training for at least four weeks with or without education and/or psychological support. We defined 'usual care' as conventional care in which the control group was not given education or any form of additional intervention. We considered participants in the following situations to be in receipt of usual care: only verbal advice was given without additional education; and medication was altered or optimised to what was considered best practice at the start of the trial for all participants. DATA COLLECTION AND ANALYSIS: We calculated mean differences (MDs) using a random-effects model. We requested missing data from the authors of the primary study. We used standard methods as recommended by The Cochrane Collaboration. MAIN RESULTS: Along with the 31 RCTs included in the previous version (2006), we included 34 additional RCTs in this update, resulting in a total of 65 RCTs involving 3822 participants for inclusion in the meta-analysis.We noted no significant demographic differences at baseline between members of the intervention group and those who received usual care. For the pulmonary rehabilitation group, the mean forced expiratory volume at one second (FEV1) was 39.2% predicted, and for the usual care group 36.4%; mean age was 62.4 years and 62.5 years, respectively. The gender mix in both groups was around two males for each female. A total of 41 of the pulmonary rehabilitation programmes were hospital based (inpatient or outpatient), 23 were community based (at community centres or in individual homes) and one study had both a hospital component and a community component. Most programmes were of 12 weeks' or eight weeks' duration with an overall range of four weeks to 52 weeks.The nature of the intervention made it impossible for investigators to blind participants or those delivering the programme. In addition, it was unclear from most early studies whether allocation concealment was undertaken; along with the high attrition rates reported by several studies, this impacted the overall risk of bias.We found statistically significant improvement for all included outcomes. In four important domains of quality of life (QoL) (Chronic Respiratory Questionnaire (CRQ) scores for dyspnoea, fatigue, emotional function and mastery), the effect was larger than the minimal clinically important difference (MCID) of 0.5 units (dyspnoea: MD 0.79, 95% confidence interval (CI) 0.56 to 1.03; N = 1283; studies = 19; moderate-quality evidence; fatigue: MD 0.68, 95% CI 0.45 to 0.92; N = 1291; studies = 19; low-quality evidence; emotional function: MD 0.56, 95% CI 0.34 to 0.78; N = 1291; studies = 19; mastery: MD 0.71, 95% CI 0.47 to 0.95; N = 1212; studies = 19; low-quality evidence). Statistically significant improvements were noted in all domains of the St. George's Respiratory Questionnaire (SGRQ), and improvement in total score was better than 4 units (MD -6.89, 95% CI -9.26 to -4.52; N = 1146; studies = 19; low-quality evidence). Sensitivity analysis using the trials at lower risk of bias yielded a similar estimate of the treatment effect (MD -5.15, 95% CI -7.95 to -2.36; N = 572; studies = 7).Both functional exercise and maximal exercise showed statistically significant improvement. Researchers reported an increase in maximal exercise capacity (mean Wmax (W)) in participants allocated to pulmonary rehabilitation compared with usual care (MD 6.77, 95% CI 1.89 to 11.65; N = 779; studies = 16). The common effect size exceeded the MCID (4 watts) proposed by Puhan 2011(b). In relation to functional exercise capacity, the six-minute walk distance mean treatment effect was greater than the threshold of clinical significance (MD 43.93, 95% CI 32.64 to 55.21; participants = 1879; studies = 38).The subgroup analysis, which compared hospital-based programmes versus community-based programmes, provided evidence of a significant difference in treatment effect between subgroups for all domains of the CRQ, with higher mean values, on average, in the hospital-based pulmonary rehabilitation group than in the community-based group. The SGRQ did not reveal this difference. Subgroup analysis performed to look at the complexity of the pulmonary rehabilitation programme provided no evidence of a significant difference in treatment effect between subgroups that received exercise only and those that received exercise combined with more complex interventions. However, both subgroup analyses could be confounded and should be interpreted with caution. AUTHORS' CONCLUSIONS: Pulmonary rehabilitation relieves dyspnoea and fatigue, improves emotional function and enhances the sense of control that individuals have over their condition. These improvements are moderately large and clinically significant. Rehabilitation serves as an important component of the management of COPD and is beneficial in improving health-related quality of life and exercise capacity. It is our opinion that additional RCTs comparing pulmonary rehabilitation and conventional care in COPD are not warranted. Future research studies should focus on identifying which components of pulmonary rehabilitation are essential, its ideal length and location, the degree of supervision and intensity of training required and how long treatment effects persist. This endeavour is important in the light of the new subgroup analysis, which showed a difference in treatment effect on the CRQ between hospital-based and community-based programmes but no difference between exercise only and more complex pulmonary rehabilitation programmes.

Feasibility and Preliminary Responses to a Screening and Brief Intervention Program for Maternal Mental Disorders Within the Context of Primary Care.

There is little evidence of the feasibility and acceptability of integrating screening, brief intervention and referral to treatment services that address depression and alcohol, tobacco and other drug (ATOD) use into antenatal care in South Africa. Data were extracted from program records on the number of eligible women screened and number meeting criteria for depression and self-reported ATOD use. 70 women completed a questionnaire examining their preliminary responses and five MOU personnel were interviewed to identify potential barriers to implementation. Of the 3407 eligible women, 1468 (43 %) women were screened for depression or ATOD use, of whom 302 (21.4 %) screened at risk for depression, 388 (26.4 %) disclosed smoking tobacco, and 29 (2 %) disclosed alcohol or other drugs (AOD). Seventy participants completed the three month follow-up interview. Depression scores decreased significantly following the intervention (t (69) = 8.51, p < 0.001) as did self-reported tobacco use (t (73) = 3.45, p < 0.001), however self-reported AOD use remained unchanged.

The unmet palliative care needs of those dying with dementia.

An estimated 33.9 million people are living with dementia worldwide. The overall estimated median survival time from onset of dementia to death is 4.1 years for men and 4.6 years for women, with longer survival times in those with early-onset dementia. Much has been discussed about the needs of this vulnerable group of people particularly in terms of their health-care and end-of-life care (EoLC) needs. However, the literature suggests that people with end-stage dementia are still not receiving adequate or appropriate EoLC. Difficulty diagnosing dementia, a stigma surrounding the disease, lack of education of the dementia disease process and the ability to identify complications encountered at end-stage dementia by health-care providers, families and carers are some of the factors preventing those with dementia receiving effective EoLC. Great strides have been made to improve dementia palliative care; however, this cohort of patients still receive fewer referrals to appropriate palliative care services than other terminally ill patients.

Qualitative case study data analysis: an example from practice.

AIM: To illustrate an approach to data analysis in qualitative case study methodology. BACKGROUND: There is often little detail in case study research about how data were analysed. However, it is important that comprehensive analysis procedures are used because there are often large sets of data from multiple sources of evidence. Furthermore, the ability to describe in detail how the analysis was conducted ensures rigour in reporting qualitative research. DATA SOURCES: The research example used is a multiple case study that explored the role of the clinical skills laboratory in preparing students for the real world of practice. Data analysis was conducted using a framework guided by the four stages of analysis outlined by Morse ( 1994 ): comprehending, synthesising, theorising and recontextualising. The specific strategies for analysis in these stages centred on the work of Miles and Huberman ( 1994 ), which has been successfully used in case study research. The data were managed using NVivo software. REVIEW METHODS: Literature examining qualitative data analysis was reviewed and strategies illustrated by the case study example provided. Discussion Each stage of the analysis framework is described with illustration from the research example for the purpose of highlighting the benefits of a systematic approach to handling large data sets from multiple sources. CONCLUSION: By providing an example of how each stage of the analysis was conducted, it is hoped that researchers will be able to consider the benefits of such an approach to their own case study analysis. IMPLICATIONS FOR RESEARCH/PRACTICE: This paper illustrates specific strategies that can be employed when conducting data analysis in case study research and other qualitative research designs.

The impact of reminiscence on the quality of life of residents with dementia in long-stay care.

BACKGROUND: There is increasing recognition of the potential use of reminiscence in maintaining or improving the quality of life of people with dementia. Despite being used widely in dementia care, evidence on the effectiveness of reminiscence remains uncertain. AIMS: This study aims to evaluate the effectiveness of a structured education-based reminiscence programme-the Dementia Education Programme Incorporating Reminiscence for Staff-for people with dementia residing in long-stay care settings in Ireland. METHODS: Dementia Education Programme Incorporating Reminiscence for Staff is a two-group, single-blind, cluster randomised trial conducted in long-stay residential care settings in Ireland. The primary outcome was the self-rated quality of life of residents as measured by the Quality of Life-Alzheimer's Disease instrument. RESULTS: Using an intention-to-treat analysis, we found that the estimated effect of the intervention on the quality of life of residents was a non-significant 3.54 (p = 0.1; 95% confidence interval -0.83, 7.90), expressed as the difference in mean improvement between the intervention and control groups. However, the per-protocol analysis yielded a significant effect for the intervention on the quality of life of residents of 5.22 (p = 0.04; 95% confidence interval 0.11, 10.34). CONCLUSIONS: Reminiscence may, in certain circumstances, be an effective care option for people with dementia in long-stay settings with potential to impact positively on the quality of life of residents.

'Seeing me through my memories': a grounded theory study on using reminiscence with people with dementia living in long-term care.

AIMS AND OBJECTIVES: To understand people with dementia, staff and relatives perspectives on reminiscence, its impact on their lives and experience of care and care giving. BACKGROUND: The quality of life of people with dementia living in long-term care is an important question for providers and policymakers. Reminiscence is thought to have potential for increasing resident-staff interaction, thereby contributing to enhanced personhood for people with dementia. Relatively little is known about the effects of reminiscence on people with dementia or staff. DESIGN: This is a grounded theory study. This design was chosen because of its focus on understanding people's behaviour, interaction and response to events. METHODS: In-depth interviews were conducted with residents with dementia (n = 11), relatives (n = 5), healthcare assistants (n = 10), nurses (n = 9) and nurse managers (n = 3). RESULTS: Reminiscence enabled staff to see and know the person beneath the dementia. It acted as … a key revealing the person to staff, enabling them to engage with the person with dementia in a different way. Knowing the person enabled staff to understand (through the lens of the person's past) and sometimes to accommodate the person's current behaviour. CONCLUSION: The theory of 'seeing me (through my memories)' was generated from the data. This theory explains that through reminiscing and engaging with the person with dementia, staff begin to see the person (their personhood) through the mirror of their memories. RELEVANCE TO CLINICAL PRACTICE: This study found that reminiscence enhanced the experience of living in long-term care for residents with dementia and working in long-term care settings for staff.

Policy-makers' views on impact of specialist and advanced practitioner roles in Ireland: the SCAPE study.

AIM: To ascertain and explore the views held by key healthcare policy-makers on the impact of clinical specialist and advanced practice nursing and midwifery roles. BACKGROUND: Specialist and advanced practice roles are common world-wide and were introduced in Ireland in 2000. After experiencing these roles for a decade, the views of healthcare policy-makers were sought as part of a national evaluation. METHODS: A qualitative, descriptive design was used. Following ethical approval, 12 policy-makers were interviewed in 2010, using a six-part interview schedule. RESULTS: Policy-makers believed that specialist and advanced practice roles resulted in better continuity of care, improved patient/client outcomes and a more holistic approach. These clinicians were also said to be leading guideline development, new initiatives in care, education of staff, audit and policy development. They lacked administrative support and research time. Budget cuts and a government-applied recruitment moratorium were said to hamper the development of specialist/advanced practice roles. CONCLUSION: Healthcare policy-makers believe that specialists and advanced practitioners contribute to higher quality patient/client care, particularly at a strategic level. IMPLICATIONS FOR NURSING MANAGEMENT: These roles could make an important contribution to future health service developments, particularly in relation to chronic-disease management and community care, where more advanced practitioner posts are required.

Factors influencing advanced practitioners' ability to enact leadership: a case study within Irish healthcare.

AIM: To report the factors that influence clinical specialists' and advanced nurse practitioners' ability to enact their clinical and professional leadership roles; findings from the SCAPE study. BACKGROUND: The importance of leadership for specialist and advanced practitioners is highlighted in the international literature and is considered an important factor in the provision of improved patient outcomes. Despite many studies identifying the barriers in developing and integrating new specialist/advanced practice roles into health services, little is known about the factors that influence the leadership dimension of their role. METHOD: A case study design involving 23 clinical specialist/advanced practitioners working in Ireland and multidisciplinary team members working with them, was used. Data were collected using interview, observation and documentary analysis. RESULTS: Four mediating factors influence the specialist/advanced practitioner's ability to perform a leadership role, namely the presence of a framework for the professional development of the role; opportunities to act as leaders; mechanisms for sustaining leadership; and personal attributes of practitioners. CONCLUSION AND IMPLICATIONS FOR NURSING MANAGEMENT: Nursing/midwifery leaders and managers at all levels have a key role in supporting leadership potential, through countering the negative impact of professional isolation, expanding opportunities for specialist/advanced practitioners to influence policy and network with wider professional groups.

Insights into the use and complexities of the Policy Delphi technique.

AIM: To describe the Policy Delphi technique and show how it was used in a research study in the Republic of Ireland. BACKGROUND: Policy Delphi is a variant of the Delphi technique, but differs in that its purpose is to explore consensus rather than aid it. It is an appropriate methodological tool for researching complex issues that benefit from the insights and consensus of a group of experts. It is useful in examining options and implications of policy and assessing their acceptability. Data sources A three-round policy Delphi study was the second phase of a sequential mixed-method design. The study was intended to examine stakeholders' perceptions of the clinical role of lecturers in nursing to identify supportive and limiting factors that affect the clinical role, with the purpose of determining a model for best practice. REVIEW METHODS: A review of literature about Policy Delphi from its development to current use (1970-2013) was undertaken to explore the technique. DISCUSSION: The complexities of using the Policy Delphi methodology to explore policy options are discussed. CONCLUSION: Policy Delphi is an underused tool that would benefit nursing research. The output from a Policy Delphi study produces a substantial number of new ideas and an evaluation of those ideas for use in decision making. IMPLICATIONS FOR RESEARCH/PRACTICE: Policy Delphi can offer researchers a means to explore levels of consensus on policy issues that have major effects on nursing developments. Practitioners may also benefit because it provides a useful way to assess and validate expert knowledge that could be contestable in a range of practice situations.

Reflections on the added value of using mixed methods in the SCAPE study.

AIM: To reflect on the added value that a mixed method design gave in a large national evaluation study of specialist and advanced practice (SCAPE), and to propose a reporting guide that could help make explicit the added value of mixed methods in other studies. BACKGROUND: Recently, researchers have focused on how to carry out mixed methods research (MMR) rigorously. The value-added claims for MMR include the capacity to exploit the strengths and compensate for weakness inherent in single designs, generate comprehensive description of phenomena, produce more convincing results for funders or policy-makers and build methodological expertise. DATA SOURCES: Data illustrating value added claims were drawn from the SCAPE study. REVIEW METHODS: Studies about the purpose of mixed methods were identified from a search of literature. DISCUSSION: The authors explain why and how they undertook components of the study, and propose a guideline to facilitate such studies. CONCLUSION: If MMR is to become the third methodological paradigm, then articulation of what extra benefit MMR adds to a study is essential. The authors conclude that MMR has added value and found the guideline useful as a way of making value claims explicit. IMPLICATIONS FOR PRACTICE/RESEARCH: The clear articulation of the procedural aspects of mixed-methods research, and identification of a guideline to facilitate such research, will enable researchers to learn more effectively from each other.

The effectiveness of a structured education pulmonary rehabilitation programme for improving the health status of people with moderate and severe chronic obstructive pulmonary disease in primary care: the PRINCE cluster randomised trial.

OBJECTIVE: To evaluate the effectiveness of a structured education pulmonary rehabilitation programme on the health status of people with chronic obstructive pulmonary disease (COPD). DESIGN: Two-arm, cluster randomised controlled trial. SETTING: 32 general practices in the Republic of Ireland. PARTICIPANTS: 350 participants with a diagnosis of moderate or severe COPD. INTERVENTION: Experimental group received a structured education pulmonary rehabilitation programme, delivered by the practice nurse and physiotherapist. Control group received usual care. MAIN OUTCOME MEASURE: Health status as measured by the Chronic Respiratory Questionnaire (CRQ) at baseline and at 12-14 weeks postcompletion of the programme. RESULTS: Participants allocated to the intervention group had statistically significant higher mean change total CRQ scores (adjusted mean difference (MD) 1.11, 95% CI 0.35 to 1.87). However, the CI does not exclude a smaller difference than the one that was prespecified as clinically important. Participants allocated to the intervention group also had statistically significant higher mean CRQ Dyspnoea scores after intervention (adjusted MD 0.49, 95% CI 0.20 to 0.78) and CRQ Physical scores (adjusted MD 0.37, 95% CI 0.14 to 0.60). However, CIs for both the CRQ Dyspnoea and CRQ Physical subscales do not exclude smaller differences as prespecified as clinically important. No other statistically significant differences between groups were seen. CONCLUSIONS: A primary care based structured education pulmonary rehabilitation programme is feasible and may increase local accessibility to people with moderate and severe COPD.

Using case study within a sequential explanatory design to evaluate the impact of specialist and advanced practice roles on clinical outcomes: the SCAPE study.

BACKGROUND: The role of the clinical nurse/midwife specialist and advanced nurse/midwife practitioner is complex not least because of the diversity in how the roles are operationalised across health settings and within multidisciplinary teams. This aim of this paper is to use The SCAPE Study: Specialist Clinical and Advanced Practitioner Evaluation in Ireland to illustrate how case study was used to strengthen a Sequential Explanatory Design. METHODS: In Phase 1, clinicians identified indicators of specialist and advanced practice which were then used to guide the instrumental case study design which formed the second phase of the larger study. Phase 2 used matched case studies to evaluate the effectiveness of specialist and advanced practitioners on clinical outcomes for service users. Data were collected through observation, documentary analysis, and interviews. Observations were made of 23 Clinical Specialists or Advanced Practitioners, and 23 matched clinicians in similar matched non-postholding sites, while they delivered care. Forty-one service users, 41 clinicians, and 23 Directors of Nursing or Midwifery were interviewed, and 279 service users completed a survey based on the components of CS and AP practice identified in Phase 1. A coding framework, and the generation of cross tabulation matrices in NVivo, was used to make explicit how the outcome measures were confirmed and validated from multiple sources. This strengthened the potential to examine single cases that seemed 'different', and allowed for cases to be redefined. Phase 3 involved interviews with policy-makers to set the findings in context. RESULTS: Case study is a powerful research strategy to use within sequential explanatory mixed method designs, and adds completeness to the exploration of complex issues in clinical practice. The design is flexible, allowing the use of multiple data collection methods from both qualitative and quantitative paradigms. CONCLUSIONS: Multiple approaches to data collection are needed to evaluate the impact of complex roles and interventions in health care outcomes and service delivery. Case study design is an appropriate methodology to use when study outcomes relate to clinical practice.
