Background To evaluate the impact of the Dementia Care in Hospitals Program (DCHP) on clinical and non-clinical staff job satisfaction, level of confidence and comfort in caring for patients with cognitive impairment (CI). Staff perceptions of how organisational support and hospital environment met the needs of patients with CI were also assessed. Methods The DCHP was implemented across four acute hospital sites across Australia. Clinical and non-clinical staff received training on CI screening and communication strategies for patients with CI. A staff satisfaction survey was administered pre- and post-implementation of the DCHP. Results One thousand seven hundred forty-eight staff received DCHP education and 1375 staff participated in the survey. Self-reported confidence and level of comfort in caring for patients with CI significantly improved following implementation. Staff also reported increased job satisfaction and organisational support at all hospital sites. Conclusions The DCHP implementation within an acute hospital setting was found to show an improvement in staff confidence, comfort, and job satisfaction when caring for patients with CI. This study has significant implications for the improvement of care for patients with CI as well as staff retention and job satisfaction. Further research is required to determine whether these improvements are sustained in the longer term.

Background Research capacity building (RCB) initiatives have gained steady momentum in health settings across the globe to reduce the gap between research evidence and health practice and policy. RCB strategies are typically multidimensional, comprising several initiatives targeted at different levels within health organisations. Research education and training is a mainstay strategy targeted at the individual level and yet, the evidence for research education in health settings is unclear. This review scopes the literature on research education programs for nurses and allied health professionals, delivered and evaluated in healthcare settings in high-income countries. Methods The review was conducted systematically in accordance with the Joanna Briggs Institute scoping review methodology. Eleven academic databases and numerous grey literature platforms were searched. Data were extracted from the included full texts in accordance with the aims of the scoping review. A narrative approach was used to synthesise findings. Program characteristics, approaches to program evaluation and the outcomes reported were extracted and summarised. Results Database searches for peer-reviewed and grey literature yielded 12,457 unique records. Following abstract and title screening, 207 full texts were reviewed. Of these, 60 records were included. Nine additional records were identified on forward and backward citation searching for the included records, resulting in a total of 69 papers describing 68 research education programs. Research education programs were implemented in fourteen different high-income countries over five decades. Programs were multifaceted, often encompassed experiential learning, with half including a mentoring component. Outcome measures largely reflected lower levels of Barr and colleagues’ modified Kirkpatrick educational outcomes typology (e.g., satisfaction, improved research knowledge and confidence), with few evaluated objectively using traditional research milestones (e.g., protocol completion, manuscript preparation, poster, conference presentation). Few programs were evaluated using organisational and practice outcomes. Overall, evaluation methods were poorly described. Conclusion Research education remains a key strategy to build research capacity for nurses and allied health professionals working in healthcare settings. Evaluation of research education programs needs to be rigorous and, although targeted at the individual, must consider longer-term and broader organisation-level outcomes and impacts. Examining this is critical to improving clinician-led health research and the translation of research into clinical practice.

IntroductionAlzheimer’s disease has a high prevalence and a substantial impact on society, as well as the individual. Findings from clinical studies to date, suggest that multiple factors are likely to contribute to the variability seen in the progression of Alzheimer’s disease. However, despite this accumulating evidence, current identified factors do not explain the full extent of disease onset. Thus, the role of additional factors needs to be explored further.One such factor is exposure to adverse childhood experiences. However, the degree of this association is unknown. This systematic review will examine the literature investigating the associations between adverse childhood experiences and the risk of Alzheimer’s disease.Methods and analysisArticles investigating associations between exposure to adverse childhood experiences and the risk of Alzheimer’s disease will be identified systematically by searching CINAHL, MEDLINE and PsycInfo using Ebscohost. No restrictions on date of publication will be applied. The search strategy will be built combining the main key elements of the Population, Exposure, Comparator, and Outcomes inclusion criteria. A meta-analysis is planned and statistical methods will be used to identify and control for heterogeneity, if possible. The development of this protocol was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols.Ethics and disseminationOnly published data will be used for this study, thus, ethical approval will not be required. Findings of the review will be published in a peer-reviewed scientific journal, and presented at national and international conferences.PROSPERO registration numberCRD42020191439.

BackgroundAlzheimer's disease is a global health concern, and with no present cure, prevention is critical. Exposure to adverse childhood experiences may increase the risk of developing Alzheimer's disease. This systematic review was conducted to synthesize the evidence on the associations between adverse childhood experiences (<18 years) and the risk of Alzheimer's disease in adulthood.MethodsA search strategy was developed and conducted to identify articles investigating the associations between exposure to adverse childhood experiences and the onset of Alzheimer's disease by searching key databases (CINAHL, MEDLINE and PsycInfo). Two reviewers independently determined the eligibility of studies according to pre-determined criteria, and assessed the methodological quality using the US National Heart, Lung and Blood Institute 14-item checklist for observational cohort and cross-sectional studies, respectively. Due to limited studies, a descriptive synthesis was performed. The protocol for this review is published in BMJ Open and registered with PROSPERO (CRD42020191439).ResultsOur search yielded 781 articles, of which three (two separate analyses from the same cohort study and one cross-sectional study) met the predetermined eligibility criteria. The methodological quality assessment yielded an overall mean score of 78.9% (range 66.6 – 84.6%). All studies found adverse childhood experiences were associated with an increased risk of Alzheimer's disease. However, there was a limited number of available studies to inform the synthesis.ConclusionsAdverse childhood experiences appear to be associated with an increased risk of Alzheimer's disease, although, further research is needed.Registration and ProtocolThe protocol for this review is registered with PROSPERO (CRD42020191439) and published with BMJ Open (Corney et al., 2021).

Accumulation of fat in the liver and skeletal muscle is associated with obesity and poor health outcomes. Liver steatosis is a characteristic of non-alcoholic fatty liver disease (NAFLD) and myosteatosis, of poor muscle quality in sarcopenia. In this study of 403 men (33–96 years), we investigated associations between the fatty liver index (FLI) and muscle density, as markers of fat accumulation in these organs. We also investigated associations between the FLI and parameters of sarcopenia, including DXA-derived appendicular lean mass (ALM) and handgrip strength by dynamometry. Muscle density was measured using pQCT at the radius and tibia. FLI was calculated from BMI, waist circumference, and levels of triglycerides and gamma-glutamyltransferase. There was a pattern of decreasing muscle density across increasing quartiles of FLI. After adjusting for age and lifestyle, mean radial muscle density in Q4 was 2.1% lower than Q1 (p < 0.001) and mean tibial muscle density was 1.8% lower in Q3 and 3.0% lower in Q4, compared to Q1 (p = 0.022 and < 0.001, respectively). After adjusting for age and sedentary lifestyle, participants in the highest FLI quartile were sixfold more likely to have sarcopenia. In conclusion, our results suggest that fat accumulation in the liver co-exists with fat infiltration into skeletal muscle.
