RESUMEN
BACKGROUND: The number of older people in prison is growing. As a result, there will also be more prisoners suffering from dementia. The support and management of this population is likely to present multiple challenges to the prison system. OBJECTIVES: To examine the published literature on the care and supervision of people living in prison with dementia and on transitioning into the community; to identify good practice and recommendations that might inform the development of prison dementia care pathways. METHODS: A scoping review methodology was adopted with reporting guided by the PRISMA extension for scoping reviews checklist and explanation. RESULTS: Sixty-seven papers were included. Most of these were from high income countries, with the majority from the United Kingdom (n = 34), followed by the United States (n = 15), and Australia (n = 12). One further paper was from India. DISCUSSION: The literature indicated that there were difficulties across the prison system for people with dementia along the pathway from reception to release and resettlement. These touched upon all aspects of prison life and its environment, including health and social care. A lack of resources and national and regional policies were identified as important barriers, although a number of solutions were also identified in the literature, including the development of locally tailored policies and increased collaboration with the voluntary sector. CONCLUSION: To our knowledge, this is the most comprehensive and inclusive review of the literature on dementia care pathways in prison to date. It has identified a number of important areas of concern and opportunities for future research across the prison system, and its operations. This will hopefully lead to the identification or adaptation of interventions to be implemented and evaluated, and facilitate the development of dementia care pathways in prisons.
RESUMEN
Introduction Childhood caries remains a major UK health issue. The COVID-19 pandemic has necessitated rapid introduction of innovative practice to minimise footfall into dental clinics. Video-based oral health education could help promote oral health advice remotely and has been included in national guidance. This systematic review evaluates the impact of video education versus written patient leaflets on knowledge and oral health behaviours in parents/carers or children.Method PubMed and Medline were searched. In total, 47 articles were identified and relevance assessed by examining titles and abstracts. Seven full-text articles were assessed and reference lists manually screened for additional publications. Three studies met the inclusion criteria.Results Only one study assessed participant knowledge gain and found no statistical significance between scores at baseline and after video, leaflet or hygienist-led education. For oral health behaviour change, one study demonstrated no significant difference in plaque score improvements between video and leaflet groups. The other showed significant improvements in plaque and bleeding scores for both leaflet and video groups compared to the control.Conclusion This review identified too few studies with heterogeneity to make conclusions on the impact of written versusvideo oral health education. A standardised outcome measurement tool is needed to evaluate the impact of current educational videos on oral health behaviour and knowledge. There is potential for video to educate the masses as we navigate through this pandemic.
RESUMEN
BACKGROUND: Type 2 diabetes is a risk factor for Alzheimer's disease (AD), and AD brain shows impaired insulin signalling. The role of peripheral insulin resistance on AD aetiopathogenesis in non-diabetic patients is still debated. Here we evaluated the influence of insulin resistance on brain glucose metabolism, grey matter volume and white matter lesions (WMLs) in non-diabetic AD subjects. METHODS: In total, 130 non-diabetic AD subjects underwent MRI and [18F]FDG PET scans with arterial cannula insertion for radioactivity measurement. T1 Volumetric and FLAIR sequences were acquired on a 3-T MRI scanner. These subjects also had measurement of glucose and insulin levels after a 4-h fast on the same day of the scan. Insulin resistance was calculated by the updated homeostatic model assessment (HOMA2). For [18F]FDG analysis, cerebral glucose metabolic rate (rCMRGlc) parametric images were generated using spectral analysis with arterial plasma input function. RESULTS: In this non-diabetic AD population, HOMA2 was negatively associated with hippocampal rCMRGlc, along with total grey matter volumes. No significant correlation was observed between HOMA2, hippocampal volume and WMLs. CONCLUSIONS: In non-diabetic AD, peripheral insulin resistance is independently associated with reduced hippocampal glucose metabolism and with lower grey matter volume, suggesting that peripheral insulin resistance might influence AD pathology by its action on cerebral glucose metabolism and on neurodegeneration.

RESUMEN
BACKGROUND: Liraglutide is a glucagon-like peptide-1 (GLP-1) analogue currently approved for type 2 diabetes and obesity. Preclinical evidence in transgenic models of Alzheimer's disease suggests that liraglutide exerts neuroprotective effects by reducing amyloid oligomers, normalising synaptic plasticity and cerebral glucose uptake, and increasing the proliferation of neuronal progenitor cells. The primary objective of the study is to evaluate the change in cerebral glucose metabolic rate after 12 months of treatment with liraglutide in participants with Alzheimer's disease compared to those who are receiving placebo. METHODS/DESIGN: ELAD is a 12-month, multi-centre, randomised, double-blind, placebo-controlled, phase IIb trial of liraglutide in participants with mild Alzheimer's dementia. A total of 206 participants will be randomised to receive either liraglutide or placebo as a daily injection for a year. The primary outcome will be the change in cerebral glucose metabolic rate in the cortical regions (hippocampus, medial temporal lobe, and posterior cingulate) from baseline to follow-up in the treatment group compared with the placebo group. The key secondary outcomes are the change from baseline to 12 months in z scores for clinical and cognitive measures (Alzheimer's Disease Assessment Scale-Cognitive Subscale and Executive domain scores of the Neuropsychological Test Battery, Clinical Dementia Rating Sum of Boxes, and Alzheimer's Disease Cooperative Study-Activities of Daily Living) and the incidence and severity of treatment-emergent adverse events or clinically important changes in safety assessments. Other secondary outcomes are 12-month change in magnetic resonance imaging volume, diffusion tensor imaging parameters, reduction in microglial activation in a subgroup of participants, reduction in tau formation and change in amyloid levels in a subgroup of participants measured by tau and amyloid imaging, and changes in composite scores using support machine vector analysis in the treatment group compared with the placebo group. DISCUSSION: Alzheimer's disease is a leading cause of morbidity worldwide. As available treatments are only symptomatic, the search for disease-modifying therapies is a priority. If the ELAD trial is successful, liraglutide and GLP-1 analogues will represent an important class of compounds to be further evaluated in clinical trials for Alzheimer's treatment.
