ZCCHC17 Modulates Neuronal RNA Splicing and Supports Cognitive Resilience in Alzheimer's Disease.

ZCCHC17 is a putative master regulator of synaptic gene dysfunction in Alzheimer's disease (AD), and ZCCHC17 protein declines early in AD brain tissue, before significant gliosis or neuronal loss. Here, we investigate the function of ZCCHC17 and its role in AD pathogenesis using data from human autopsy tissue (consisting of males and females) and female human cell lines. Co-immunoprecipitation (co-IP) of ZCCHC17 followed by mass spectrometry analysis in human iPSC-derived neurons reveals that ZCCHC17's binding partners are enriched for RNA-splicing proteins. ZCCHC17 knockdown results in widespread RNA-splicing changes that significantly overlap with splicing changes found in AD brain tissue, with synaptic genes commonly affected. ZCCHC17 expression correlates with cognitive resilience in AD patients, and we uncover an APOE4-dependent negative correlation of ZCCHC17 expression with tangle burden. Furthermore, a majority of ZCCHC17 interactors also co-IP with known tau interactors, and we find a significant overlap between alternatively spliced genes in ZCCHC17 knockdown and tau overexpression neurons. These results demonstrate ZCCHC17's role in neuronal RNA processing and its interaction with pathology and cognitive resilience in AD, and suggest that the maintenance of ZCCHC17 function may be a therapeutic strategy for preserving cognitive function in the setting of AD pathology.

Patient-maintained versus anaesthetist-controlled propofol sedation during elective primary lower-limb arthroplasty performed under spinal anaesthesia: a randomised controlled trial.

BACKGROUND: Patient-maintained propofol TCI sedation (PMPS) allows patients to titrate their own target-controlled infusion (TCI) delivery of propofol sedation using a handheld button. The aim of this RCT was to compare PMPS with anaesthetist-controlled propofol TCI sedation (ACPS) in patients undergoing elective primary lower-limb arthroplasty surgery under spinal anaesthesia. METHODS: In this single-centre open-label investigator-led study, adult patients were randomly assigned to either PMPS or ACPS during their surgery. Both sedation regimes used Schnider effect-site TCI modelling. The primary outcome measure was infusion rate adjusted for weight (expressed as mg kg-1 h-1). Secondary outcomes measures included depth of sedation, occurrence of sedation-related adverse events and time to medical readiness for discharge from the postanaesthsia care unit (PACU). RESULTS: Eighty patients (48 female) were randomised. Subjects using PMPS used 39.3% less propofol during the sedation period compared with subjects in group ACPS (1.56 [0.57] vs 2.57 [1.33] mg kg-1 h-1; P<0.001), experienced fewer discrete episodes of deep sedation (0 vs 6; P=0.0256), fewer airway/breathing adverse events (odds ratio [95% confidence interval]: 2.94 [1.31-6.64]; P=0.009) and were ready for discharge from PACU more quickly (8.94 [5.5] vs 13.51 [7.2] min; P=0.0027). CONCLUSIONS: Patient-maintained propofol sedation during lower-limb arthroplasty under spinal anaesthesia results in reduced drug exposure and fewer episodes of sedation-related adverse events compared with anaesthetist-controlled propofol TCI sedation. To facilitate further investigation of this procedural sedation technique, PMPS-capable TCI infusion devices should be submitted for regulatory approval for clinical use. CLINICAL TRIAL REGISTRATION: ISRCTN29129799.

The Role of Online Support Groups in Helping Individuals Affected by HIV and AIDS: Scoping Review of the Literature.

BACKGROUND: Online support groups provide opportunities for individuals affected by HIV and AIDS to seek information, advice, and support from peers. However, whether and how engagement with online support groups helps individuals affected by HIV and AIDS remains unclear, as does the nature of the evidence on this topic. OBJECTIVE: This scoping review sought to explore whether engagement with HIV and AIDS-related online support groups benefits members in terms of psychosocial well-being and illness management, whether members experienced any negative aspects of these groups, and what types of social support are exchanged within HIV and AIDS-related online support groups. METHODS: A scoping review of English-language articles (including both qualitative and quantitative studies) was undertaken using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The databases searched included MEDLINE, PubMed, EMBASE, CINAHL, PsycINFO, CENTRAL (Cochrane Register of Controlled Trials), and Scopus. Key findings were synthesized using a narrative and thematic approach. RESULTS: A total of 22 papers met the inclusion criteria from an initial pool of 3332 abstracts. These papers included 23% (5/22) quantitative studies, 9% (2/22) mixed methods studies, and 68% (15/22) qualitative studies published between 2007 and 2019. Cross-sectional evidence suggests that engagement with HIV and AIDS-related online support groups is empowering for members and may lead to a range of psychosocial benefits. Furthermore, qualitative evidence suggests that these groups provide an opportunity to connect with similar people and share experiences. This can help improve self-worth, reduce stigma, facilitate improved illness management, and gain greater confidence when interacting with health professionals. However, online support groups are not without their limitations as qualitative evidence suggests that users may encounter examples of interpersonal conflict between members as well as be exposed to challenging content. Finally, HIV and AIDS-related online support groups are avenues through which individuals can solicit support, most commonly informational or emotional. CONCLUSIONS: HIV and AIDS-related online support groups may have some benefits for members, particularly in terms of providing social support. There is a need for a systematic review of this literature that includes an assessment of the methodological quality of the available evidence.

Prevalence of dental anxiety in children and adolescents globally: A systematic review with meta-analyses.

BACKGROUND: Dental anxiety (DA) negatively impacts oral health-related quality of life, and patients with DA usually require more dental treatment time. AIM: To describe the global prevalence of DA in children and adolescents and to examine the influence of individual factors (age, sex, and caries experience) and variables related to DA measurement on pooled prevalence. DESIGN: Systematic review with meta-analyses of observational studies published between 1985 and 2020 (PROSPERO CRD42014013879). RESULTS: Searches yielded 1207 unique records; 224 full-text articles were screened, and 50 studies were used in the qualitative and quantitative synthesis. No study was considered as having high methodological quality according to 'The Joanna Briggs Institute assessment tool'. Overall pooled DA prevalence was 23.9% (95% CI 20.4, 27.3). Pooled prevalence in preschoolers, schoolchildren, and adolescents was as follows: 36.5% (95% CI 23.8, 49.2), 25.8% (95% CI 19.5, 32.1), and 13.3% (95% CI 9.5, 17.0), respectively. DA was significantly more prevalent in preschool children (one study) and schoolchildren (two studies) with caries experience and in female adolescents (one study). The scale used for DA assessment was shown to influence pooled prevalence in preschoolers and adolescents. CONCLUSION: DA is a frequent problem in 3- to 18-year-olds worldwide, more prevalent in schoolchildren and preschool children than in adolescents.

Translation and validation of the Revised Dental Beliefs Survey (DBS-R) in China.

Patient perceptions of behaviours and attitudes of dentists are associated with dental fear and poor dental attendance in Western countries. However, there is a paucity of research exploring patient perceptions of the dentist in China. One reason for this may be the lack of a valid and reliable scale in Chinese (Standard Mandarin) to measure this. This study aimed to translate the Revised Dental Beliefs Survey (DBS-R) into Chinese and then explore the reliability and validity of this measure (both the short and longer versions) in a Chinese population. We translated the DBS-R using the forwards-backwards method and pilot tested it on a small sample of adults in China. Following this, 480 Chinese adults completed the newly translated scale, as well as well as a standardised dental anxiety questionnaire (the Modified Dental Anxiety Scale Chinese version) to test convergent validity. 109 participants completed the DBS-R again 2 weeks later for test-retest reliability. Both versions of the Chinese DBS-R were internally consistent and demonstrated convergent validity; test-retest reliability was also good. Both versions of the scale performed similarly, but for now we would suggest the 28-item version may be superior as items relating to the technical competence of the dentist appear important to Chinese adults.

Positive mood on the day of influenza vaccination predicts vaccine effectiveness: A prospective observational cohort study.

Influenza vaccination is estimated to only be effective in 17-53% of older adults. Multiple patient behaviors and psychological factors have been shown to act as 'immune modulators' sufficient to influence vaccination outcomes. However, the relative importance of such factors is unknown as they have typically been examined in isolation. The objective of the present study was to explore the effects of multiple behavioral (physical activity, nutrition, sleep) and psychological influences (stress, positive mood, negative mood) on the effectiveness of the immune response to influenza vaccination in the elderly. A prospective, diary-based longitudinal observational cohort study was conducted. One hundred and thirty-eight community-dwelling older adults (65-85years) who received the 2014/15 influenza vaccination completed repeated psycho-behavioral measures over the two weeks prior, and four weeks following influenza vaccination. IgG responses to vaccination were measured via antigen microarray and seroprotection via hemagglutination inhibition assays at 4 and 16weeks post-vaccination. High pre-vaccination seroprotection levels were observed for H3N2 and B viral strains. Positive mood on the day of vaccination was a significant predictor of H1N1 seroprotection at 16weeks post-vaccination and IgG responses to vaccination at 4 and 16weeks post-vaccination, controlling for age and gender. Positive mood across the 6-week observation period was also significantly associated with post-vaccination H1N1 seroprotection and IgG responses to vaccination at 16weeks post-vaccination, but in regression models the proportion of variance explained was lower than for positive mood on the day of vaccination alone. No other factors were found to significantly predict antibody responses to vaccination. Greater positive mood in older adults, particularly on the day of vaccination, is associated with enhanced responses to vaccination.

'You have to treat the person, not the mouth only': UK dentists' perceptions of communication in patient consultations.

Effective communication between patients and health professionals is a key component of patient-centred care. Although there is a large body of literature focusing on doctor-patient communication, there has been limited research related to dentist-patient communication, especially presented from the dentists' perspective. The aim of our study was to explore UK dentists' perceptions of communication in their consultations, and the factors they perceive may influence this. We conducted semi-structured interviews with eight dentists in UK dental NHS practices. Thematic analysis revealed three themes ('Treating the whole person', 'Barriers to patient-centred communication' and 'Mutuality of communication'), which reflected the dentists' perceptions of their own communication during consultations, the patients' interaction skills, attitudes (and characteristics that may affect them), and external factors, such as time constraints, that can influence dentist-patients' encounters. These in-depth accounts are valuable, in that we see what dentists perceive is important, obstructive and facilitative. They report using a patient-centred approach in their everyday dental practice; however this is often difficult due to factors such as time constraints. Although they emphasized that the patient has an active role to play in the communication process, it may be the case that they also need to play their part in facilitating this.

Dentists' use of validated child dental anxiety measures in clinical practice: a mixed methods study.

BACKGROUND: Assessing anxiety is an important part of the assessment of a child presenting for dental treatment; however, the use of dental anxiety scales in practice is not well-documented. AIMS: To introduce child dental anxiety scales, and to monitor the extent to which dentists used them; to explore the experience and views of dentists regarding anxiety assessment. DESIGN: A mixed-methods design was employed. METHOD: A protocol for child anxiety assessment was introduced to paediatric dentists in Eastman Dental Hospital. After 6 months, 100 patient files were audited to examine compliance with the protocol. Fourteen dentists were interviewed to explore their experience and views regarding anxiety assessment. RESULTS: Only five patients were assessed using the scales. Thematic analysis of the dentist interviews revealed three themes: 'Clinical observations and experience: The gold standard'; 'Scales as an estimate or adjunct'; and 'Shortcomings and barriers to using scales'. CONCLUSIONS: The dentists in our study did not use anxiety scales, instead they rely on their own experience/judgement. Therefore, scales should be recommended as an adjunct to judgement. Brief scales are recommended as clinicians lack time and expertise in administering anxiety questionnaires. Advantages of using scales and hands-on experience could be incorporated more in undergraduate training.

How to Screen for Non-Adherence to Antihypertensive Therapy.

The quality of assessment of non-adherence to treatment in hypertensive is poor. Within this review, we discuss the different methods used to assess adherence to blood-pressure-lowering medications in hypertension patients. Subjective reports such as physicians' perceptions are inaccurate, and questionnaires completed by patients tend to overreport adherence and show a low diagnostic specificity. Indirect objective methods such as pharmacy database records can be useful, but they are limited by the robustness of the recorded data. Electronic medication monitoring devices are accurate but usually track adherence to only a single medication and can be expensive. Overall, the fundamental issue with indirect objective measures is that they do not fully confirm ingestion of antihypertensive medications. Detection of antihypertensive medications in body fluids using liquid chromatography-tandem mass spectrometry is currently, in our view, the most robust and clinically useful method to assess non-adherence to blood-pressure-lowering treatment. It is particularly helpful in patients presenting with resistant, refractory or uncontrolled hypertension despite the optimal therapy. We recommend using this diagnostic strategy to detect non-adherence alongside a no-blame approach tailoring support to address the perceptions (e.g. beliefs about the illness and treatment) and practicalities (e.g. capability and resources) influencing motivation and ability to adhere.

The impact of amelogenesis imperfecta and support needs of adolescents with AI and their parents: an exploratory study.

BACKGROUND: Amelogenesis imperfecta (AI) is a rare inherited dental defect where enamel does not form properly on the teeth. Research has shown that adolescents with AI may experience adverse psychosocial effects; however the impact on parents has not been explored. AIMS: We aimed to explore: (1) experience and perceptions of AI from both the adolescent and their parent's perspective (2) their views on the usefulness of an online support group (OSG) for patients/parents and the potential salient functions of such a resource. DESIGN: We conducted two focus groups; one for adolescent AI patients and one for their parents. Transcripts were analysed using Thematic Analysis. RESULTS: Three themes emerged from the data: 'Living with AI: Do I look bothered?', 'Need for the 'right' online environment' and 'Support needs: Information and beyond'. CONCLUSIONS: The adolescents did not appear to experience adverse psychosocial effects of having AI, which was contrary to their parents' perceptions. Parents reported some adverse consequences of having a child with AI (e.g., practical challenges). If an OSG was to be developed, it would need to be primarily information based and moderated by an AI specialist. Parents may benefit from additional support beyond that of information, such as emotional and tangible support.

Barriers and facilitators to using an objective risk communication tool during primary care dental consultations: A Theoretical Domains Framework (TDF) informed qualitative study.

OBJECTIVES: Objective risk communication tools can supplement clinical judgement and support the understanding of potential health risks. This study used the Theoretical Domains Framework (TDF) to identify barriers and facilitators to implementing a risk communication aid within primary care dental consultations. METHODS: Dentists (N = 13), recruited via a dental practice database and through professional contacts were interviewed using a TDF-informed semi-structured interview schedule. Data were analysed inductively and deductively coding the themes using the TDF. RESULTS: Eight theoretical domains (environmental context and resources; beliefs about consequences; goals; memory, attention, and decision processes; optimism; reinforcement; social influences and behavioural regulation) and thirteen sub-themes were identified. Insufficient resources and patient factors were commonly encountered barriers and led to increasing pressure to prioritise other tasks. Whilst dentists had a favourable view towards a risk communication aid and acknowledged its benefits, some were sceptical about its ability to facilitate behaviour change. Self-monitoring strategies and colleague support facilitated tool usage. CONCLUSIONS: This study identified six barriers and seven facilitators to implementing a risk communication tool within primary care dental settings. Dentists appreciated the value of using a risk communication tool during dental consultations, although some required further support to integrate the tool into practice. CLINICAL SIGNIFICANCE: Our findings provide a sound theoretical base for interventions aimed at facilitating patient behaviour change through the use of risk communication in dentistry. Further research should apply behavioural science to support the implementation of the tool in clinical practice.

Optimizing mood prior to influenza vaccination in older adults: A three-arm randomized controlled trial.

OBJECTIVE: This trial explored the psychological and immunological effects of two brief interventions, targeting improving positive mood, administered to older adults immediately prior to influenza vaccination. The primary aim was to examine whether the interventions resulted in greater positive mood compared to usual care, and if so, which was superior. Secondary outcomes included antibody responses to vaccination and feasibility of collecting clinical outcome data (e.g., respiratory infections). METHOD: Six hundred and fifty-four older adults (65-85 years) participated in a three-arm, parallel, randomized controlled trial between September 2019 and May 2020. Immediately prior to receiving an adjuvanted trivalent influenza vaccine (Fluad, Seqirus UK Ltd), participants viewed one of two brief (15-min) video-based positive mood interventions (one fixed content, one allowing participant choice) or received usual care. State affect was measured immediately prior to, and following, intervention exposure or usual care. Antibody responses were measured prevaccination and 4 weeks postvaccination. Clinical outcomes were extracted from primary care records for 6 months following vaccination. RESULTS: Both interventions were equally effective at improving mood prior to vaccination compared to usual care. Antibody responses were highly robust with postvaccination seroprotection rates of > 88% observed for all vaccine strains. Antibody responses did not significantly differ between groups. Clinical outcome data were feasible to collect. CONCLUSIONS: Brief psychological interventions can improve mood prior to vaccination. However, altering antibody responses to highly immunogenic adjuvanted vaccines may require more targeted or prolonged interventions. The provision of choice did not notably enhance the interventions impact on mood or antibody outcomes. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Alzheimer's disease CSF biomarkers correlate with early pathology and alterations in neuronal and glial gene expression.

INTRODUCTION: Normal pressure hydrocephalus (NPH) patients undergoing cortical shunting frequently show early AD pathology on cortical biopsy, which is predictive of progression to clinical AD. The objective of this study was to use samples from this cohort to identify CSF biomarkers for AD-related CNS pathophysiologic changes using tissue and fluids with early pathology, free of post-mortem artifact. METHODS: We analyzed Simoa, proteomic, and metabolomic CSF data from 81 patients with previously documented pathologic and transcriptomic changes. RESULTS: AD pathology on biopsy correlates with CSF ß-amyloid-40/42, neurofilament light chain (NfL), and phospho-tau-181(p-tau181)/ß-amyloid-42, while several gene expression modules correlate with NfL. Proteomic analysis highlights 7 core proteins that correlate with pathology and gene expression changes on biopsy, and metabolomic analysis of CSF identifies disease-relevant groups that correlate with biopsy data.. DISCUSSION: As additional biomarkers are added to AD diagnostic panels, our work provides insight into the CNS pathophysiology these markers are tracking.

Behaviour support in dentistry: A Delphi study to agree terminology in behaviour management.

OBJECTIVES: Dental behaviour support (DBS) describes all specific techniques practiced to support patients in their experience of professional oral healthcare. DBS is roughly synonymous with behaviour management, which is an outdated concept. There is no agreed terminology to specify the techniques used to support patients who receive dental care. This lack of specificity may lead to imprecision in describing, understanding, teaching, evaluating and implementing behaviour support techniques in dentistry. Therefore, this e-Delphi study aimed to develop a list of agreed labels and descriptions of DBS techniques used in dentistry and sort them according to underlying principles of behaviour. METHODS: Following a registered protocol, a modified e-Delphi study was applied over two rounds with a final consensus meeting. The threshold of consensus was set a priori at 75%. Agreed techniques were then categorized by four coders, according to behavioural learning theory, to sort techniques according to their mechanism of action. RESULTS: The panel (n = 35) agreed on 42 DBS techniques from a total of 63 candidate labels and descriptions. Complete agreement was achieved regarding all labels and descriptions, while agreement was not achieved regarding distinctiveness for 17 techniques. In exploring underlying principles of learning, it became clear that multiple and differing principles may apply depending on the specific context and procedure in which the technique may be applied. DISCUSSION: Experts agreed on what each DBS technique is, what label to use, and their description, but were less likely to agree on what distinguishes one technique from another. All techniques were describable but not comprehensively categorizable according to principles of learning. While objective consistency was not attained, greater clarity and consistency now exists. The resulting list of agreed terminology marks a significant foundation for future efforts towards understanding DBS techniques in research, education and clinical care.

Further evidence of reliability and validity of the Huntington's disease quality of life battery for carers: Italian and French translations.

BACKGROUND: Existing research suggests that family caregivers of persons with Huntington's disease (HD) face a distinct series of problems, linked to the complex nature of the disease. Aubeeluck and Buchanan (Clin Genet, 71(5):434-445, 2007) developed and validated a disease-specific measure used to explore caregivers quality of life and assess the efficacy of therapeutic interventions. This current study builds on this research through the validation of French and Italian translations of the Huntington's disease quality of life battery for carers (HDQoL-C). METHOD: A total of 301 family carers completed the HDQoL-C. Participants were recruited through the "Euro-HDB" study which is measuring the burden in HD across Europe and the USA. RESULTS: Factor analysis demonstrated good internal consistency, reliability and congruent validity. Carers who cared for patients with less clinically severe symptoms reported significantly better QoL than carers of patients with more clinically severe symptoms. DISCUSSION: Findings indicate the HDQoL-C is multi-lingual, multi-cultural and easily applicable in other languages.

An exploratory study investigating children's perceptions of dental behavioural management techniques.

BACKGROUND: Behaviour management techniques (BMTs) are utilised by dentists to aid children's dental anxiety (DA). Children's perceptions of these have been underexplored, and their feedback could help inform paediatric dentistry. AIM: To explore children's acceptability and perceptions of dental communication and BMTs and to compare these by age, gender, and DA. DESIGN: A total of sixty-two 9- to 11-year-old school children participated in the study. Children's acceptability of BMTs was quantified using a newly developed Likert scale, alongside exploration of children's experiences and perceptions through interviews. anova and t-tests explored BMT acceptability ratings by age, gender, and DA. Thematic analysis was used to analyse interviews. FINDINGS: Statistical analyses showed no effect of age, gender, or DA upon BMT acceptability. Children generally perceived the BMTs as acceptable or neutral; stop signals were the most acceptable, and voice control the least acceptable BMT. Beneficial experiences of distraction and positive reinforcement were common. Children described the positive nature of their dentist's communication and BMT utilisation. CONCLUSION: Dental anxiety did not affect children's perceptions of BMTs. Children were generally positive about dentist's communication and established BMTs. Children's coping styles may impact perceptions and effectiveness of BMTs and should be explored in future investigations.

Factors within A Veterinarian-Cattle Farmer Relationship That May Impact on Biosecurity Being Carried out on Farms: An Exploratory Study.

Veterinarians (vets) appear to be one of the main gateways to biosecurity information for cattle farmers, and therefore are likely to affect the implementation of these measures. The aim of this study was to explore factors within the vet-farmer relationship that may impact on biosecurity being carried out on cattle farms in England. Interviews were conducted with cattle farmers and large-animal vets, with a focus on individuals deemed to implement good levels of biosecurity or those working with said individuals. The questions explored how each stakeholder felt the communication occurred between the groups and the perceived consequential influence each had on the other. Inductive Thematic analysis was used to explore participants' experience of vet-farmer interactions with a focus on areas of reciprocity between the two groups. Five primary themes were identified. Factors within the vet-cattle farmer relationship, such as trust and familiarity, which were interconnected with time spent with each other, appeared to influence the uptake of biosecurity measures on cattle farms. These factors purportedly impacted the ability of vet-farmer pairs to have cooperative discussions and enter into shared decision-making. In order to enhance animal and human health and welfare, these relationship factors might be key to the development of sustainable optimisation frameworks.

Patients' experiences of cannulation of arteriovenous access for haemodialysis: A qualitative systematic review.

INTRODUCTION: Cannulation is an essential part of haemodialysis with arteriovenous access. Patients' experiences of cannulation for haemodialysis are problematic but poorly understood. This review aims to synthesise findings related to patients' experiences of cannulation for haemodialysis from qualitative studies, providing a fuller description of this phenomenon. METHODS: Eligibility criteria defined the inclusion of studies with a population of patients with end-stage kidney disease on haemodialysis. The phenomena of interest was findings related to patients' experiences of cannulation for haemodialysis and the context was both in-centre and home haemodialysis. MedLine, CINAHL, EMBASE, EMCARE, BNI, PsycInfo and PubMed were last searched between 20/05/2019 and 23/05/2019. The quality of studies was assessed using the using Joanna Briggs Critical Appraisal Checklist for Qualitative Research. Meta-aggregation was used to synthesise findings and CERQual to assess the strength of accumulated findings. RESULTS: This review included 26 studies. The subject of included studies covered cannulation, pain, experiences of vascular access, experiences of haemodialysis and a research priority setting exercise. From these studies, three themes were meta-aggregated: (1) Cannulation for haemodialysis is an unpleasant, abnormal and unique procedure associated with pain, abnormal appearance, vulnerability and dependency. (2) The necessity of cannulation for haemodialysis emphasises the unpleasantness of the procedure. Success had multiple meanings for patients and patients worry about whether the needle insertion will be successful. (3) Patients survive unpleasant, necessary and repetitive cannulation by learning to tolerate cannulation and exerting control over the procedure. Feeling safe can help them tolerate cannulation better and the cannulator can invoke feeling safe. However, some patients still avoid cannulation, due to its unpleasantness. CONCLUSIONS: Cannulation is a pervasive procedure that impacts on patients' experiences of haemodialysis. This review illuminates further patients' experiences of cannulation for haemodialysis, indicating how improvements can be made to cannulation. REGISTRATION: PROSPERO (CRD42019134583).

The use of theories, models, and frameworks to inform the uptake of evidence-based practices in veterinary medicine - a scoping review.

Evidence-based practices (EBPs) provide strategies to improve the health, welfare and productivity of animal species. However, ensuring implementation and uptake into routine practice of these EBPs is often challenging. In human health research, one approach used to improve uptake of EBPs is the use of theories, models and/or frameworks (TMFs), however the extent of the use of this approach in veterinary medicine is unknown. The aim of this scoping review was to identify existing veterinary uses of TMFs to inform the uptake of EBPs, and to understand the focus of these applications. Searches were conducted in CAB Abstracts, MEDLINE, Embase and Scopus, alongside grey literature, and ProQuest Dissertations & Theses. The search strategy consisted of a list of known existing TMFs that have been used to improve uptake of EBPs in human health, alongside more generic terminology for implementation and terminology relevant to veterinary medicine. Peer reviewed journal articles and grey literature detailing the use of a TMF to inform uptake of EBP(s) in a veterinary context were included. The search identified 68 studies that met the eligibility criteria. Included studies represented a diverse spread of countries, areas of veterinary concern and EBP. A range of 28 different TMFs were used, although the Theory of Planned Behaviour (TPB) predominated, featuring in 46% of included studies (n = 31). The majority of studies (n = 65, 96%) utilised a TMF with the aim to understand and/or explain what influences implementation outcomes. Only 8 studies (12%) reported the use of a TMF alongside/in conjunction with the actual implementation of an intervention. It is clear there has been some use to date of TMFs to inform uptake of EBPs in veterinary medicine, however it has been sporadic. There has been a heavy reliance on usage of the TPB and other similar classic theories. This has typically been to inform the understanding of factors, such as barriers and facilitators, that may influence the outcome of an implementation effort without then applying this knowledge to the actual implementation of an intervention. Furthermore, there has been a lack of acknowledgement of wider contextual factors and consideration of sustainability of interventions. There is clear potential to increase and expand the usage of TMFs to improve uptake of EBPs in veterinary medicine, including utilising a wider range of TMFs and developing interdisciplinary collaborations with human implementation experts.
