Evaluating the association between diabetes, cognitive decline and dementia

The aim of this article is to review the association between diabetes mellitus, cognitive decline and dementia, including the effects of cognitive decline and dementia on self management of diabetes. This is a literature review of primary research articles. A number of contemporary research articles that met the inclusion criteria were selected for this review paper. These articles were selected using a number of search strategies and electronic databases, such as EBSCOhost Research and SwetsWise databases. The duration of diabetes, glycated haemoglobin levels and glycaemic fluctuations were associated with cognitive decline and dementia. Similarly, hypoglycaemia was significantly related to increased risk of developing cognitive decline and dementia. Furthermore, cognitive decline and dementia were associated with poorer diabetes management. There is evidence of the association between diabetes, cognitive decline and dementia including the shared pathogenesis between diabetes and Alzheimer’s disease. In addition, the self management of diabetes is affected by dementia and cognitive decline. It could be suggested that the association between diabetes and dementia is bidirectional with the potential to proceed to a vicious cycle. Further studies are needed in order to fully establish the relationship between diabetes, cognitive decline and dementia. Patients who have diabetes and dementia could benefit from structured education strategies, which should involve empowerment programmes and lifestyle changes. The detection of cognitive decline should highlight the need for education strategies.

Evaluation of the role of enteral nutrition in managing patients with diabetes: a systematic review.

The aim of this systematic review is to evaluate the role of enteral nutrition in managing patients with diabetes on enteral feed. The prevalence of diabetes is on the increase in the UK and globally partly due to lack of physical activities, poor dietary regimes and genetic susceptibility. The development of diabetes often leads to complications such as stroke, which may require enteral nutritional support. The provision of enteral feeds comes with its complications including hyperglycaemia which if not managed can have profound consequences for the patients in terms of clinical outcomes. Therefore, it is essential to develop strategies for managing patients with diabetes on enteral feed with respect to the type and composition of the feed. This is a systematic review of published peer reviewed articles. EBSCOhost Research, PubMed and SwetsWise databases were searched. Reference lists of identified articles were reviewed. Randomised controlled trials comparing enteral nutrition diabetes specific formulas with standard formulas were included. The studies which compared diabetes specific formulas (DSF) with standard formulas showed that DSF was more effective in controlling glucose profiles including postprandial glucose, HbA1c and insulinemic response. The use of DSF appears to be effective in managing patients with diabetes on enteral feed compared with standard feed.

Enteral Nutrition in Dementia: A Systematic Review

The aim of this systematic review is to evaluate the role of enteral nutrition in dementia. The prevalence of dementia is predicted to rise worldwide partly due to an aging population. People with dementia may experience both cognitive and physical complications that impact on their nutritional intake. Malnutrition and weight loss in dementia correlates with cognitive decline and the progress of the disease. An intervention for long term eating difficulties is the provision of enteral nutrition through a Percutaneous Endoscopic Gastrostomy tube to improve both nutritional parameters and quality of life. Enteral nutrition in dementia has traditionally been discouraged, although further understanding of physical, nutritional and quality of life outcomes are required. The following electronic databases were searched: EBSCO Host, MEDLINE, PubMed, Cochrane Database of Systematic Reviews and Google Scholar for publications from 1st January 2008 and up to and including 1st January 2014. Inclusion criteria included the following outcomes: mortality, aspiration pneumonia, pressure sores, nutritional parameters and quality of life. Each study included separate analysis for patients with a diagnosis of dementia and/or neurological disease. Retrospective and prospective observational studies were included. No differences in mortality were found for patients with dementia, without dementia or other neurological disorders. Risk factors for poor survival included decreased or decreasing serum albumin levels, increasing age or over 80 years and male gender. Evidence regarding pneumonia was limited, although did not impact on mortality. No studies explored pressure sores or quality of life.

The Use of Enteral Nutrition in the Management of Stroke

This article discusses the use of enteral nutrition in the management of stroke. Stroke is a major source of disability, including dysphagia. The clinical manifestation of swallowing difficulties in stroke patients may lead to malnutrition which has implications for health status and clinical outcomes including morbidity, mortality and cost to the health service. The prevalence of malnutrition following an acute stroke could range from 8% to 34%. Therefore, the need to develop and implement the use of enteral nutrition support in stroke patients becomes pertinent. A range of enteral feeding tubes and feeding methods may be used to support stroke patients who are unable to meet their nutritional requirements through oral intake alone, although each of these approaches has its merits and limitations. Based on this review, there is evidence that enteral nutrition support is a useful method of providing nutrition for patients with dysphagia following a stroke in order to enhance their nutritional status and promote their health. However, there are challenges in the use of enteral tube feeding in these patients.

Recent Advances in Enteral Nutrition

There have been significant advances in the provision of enteral nutrition support in the acute and community healthcare settings.[...].

Evaluation of the Accuracy of Capillary Hydroxybutyrate Measurement Compared with Other Measurements in the Diagnosis of Diabetic Ketoacidosis: A Systematic Review

A complication of diabetes is diabetic ketoacidosis (DKA), which if left untreated is a life threatening condition. Prompt and accurate diagnosis of DKA is required for the commencement of life saving interventions. Measurements of ketone bodies in DKA have usually been through nitroprusside urine acetoacetate testing. The aim of this systematic review was to examine whether capillary β-hydroxybutyrate (β-OHB) testing is more accurate compared to other diagnostic methods of DKA. The following electronic databases were searched: EBSCO Host, MEDLINE, PSYCHInfo, CINAHL and Science Direct for publications from 1 January 2005 and up to and including 1 January 2016. Inclusion criteria were: Adults 18 years and over and known type 1 or type 2 diabetes. Retrospective and prospective observation studies were included. A total of nine studies met the inclusion criteria. Capillary β-OHB was found to have high sensitivity, specificity, positive predictive value and negative predictive value in identifying DKA compared to urinary ketone testing.

Oral and enteral nutrition in dementia: an overview.

The number of people currently living with dementia in the UK is estimated to be 850 000 and this is expected to rise to over 1 million by the year 2025. Dementia is a progressive terminal disease and the rate of decline is unique to each person; however, cognitive deterioration can be accelerated by undernutrition. This article discusses evidence-based approaches in the use of oral and enteral nutrition interventions for people living with dementia and ways to support their caregivers. The discussion of interventions to improve oral nutrition includes changes to the environment, support with feeding difficulties, nutritional supplements and education and training for caregivers.

Pressure injuries in people with darker skin tones: A literature review

AIMS AND OBJECTIVES In this article, we aimed to explore the literature to ascertain what research evidence exists in relation to the identification of pressure injuries in people with dark skin tones. BACKGROUND Pressure injuries development has been widely researched and documented; however, much of this work does not address ethnicity or race and assumes Caucasian-ness. Thus, the perceptions of people with dark skin tones and the influence of skin pigmentation on identification and management of pressure injuries is under examined. DESIGN Literature review. METHODS A comprehensive electronic database search was undertaken of PubMed, Cumulative Index for Nursing and Allied Health Literature, Cochrane and British Nursing Index (BNI) between 1990-July 2016. Alongside the electronic data, journals, books, papers from conferences, relevant national and international organisations and reference lists were also used to help source key studies. RESULTS A search of the literature revealed 11 relevant articles. The foci of studies included the following: risk of sustaining a pressure injuries based on skin tones, identification of pressure injuries amongst people with dark skin tones, pressure injuries and place of care and socio-economic impact on pressure injuries development. Overall, findings indicate that people with darker skin tones are more likely to develop higher stage pressure injuries. Reasons for this are not fully elucidated; however, it may be associated with current skin assessment protocols being less effective for people who have darker skin tones resulting in early damage arising from pressure not being recognised. CONCLUSION From the literature reviewed, it can be seen that there is a lack of guidance and evidence, and people with darker skin tones are more likely in comparison with people presenting as Caucasian to develop higher stage pressure injuries. RELEVANCE TO CLINICAL PRACTICE The current literature suggests a need for researchers and clinicians to consider skin tone variances rather than ethnicity when exploring comprehensive skin assessment.

Elements of a sustainable, competent, and empathetic workforce to support patients with dementia during an acute hospital stay: A comprehensive literature review

Internationally, there has been a focus on the development of acute hospital workforces to support and care for people with dementia. Recommendations and initiatives to improve person-centred care in acute hospitals have included: education and training, dementia-specific roles, clinical leads, and environment changes. The aim of this literature review is to understand the elements of a sustainable, competent, and empathetic acute hospital workforce providing person-centred care for patients with dementia. The following databases were searched for literature published in English from January 1, 2006, to August 1, 2016: CINHAL, MEDLINE, PsychINFO, PubMed, and Science Direct. A thematic analysis was applied to develop a meta-synthesis of the data. A total of 12 papers with a range of methodological approaches from various countries were included. Emergent themes were as follows: understanding the current workforce, implementation and evaluation of training, and exploration of new and existing roles. An important element was the sustainability of acute hospital workforces competent in dementia care, as studies highlighted an ageing nursing population and a high turnover of staff. Dementia awareness training was sustainable, although there was a lack of consistency in the length, content, and delivery, which had a viable impact on the provision of empathetic and person-centred care. The lack of consistency of training and specialist dementia roles restricts recommendations from a robust evidence base.

The impact of dementia in the prison setting: A systematic review

Older prisoners are the fastest growing group in the prison population, with an accelerated aging process they are at a high risk of developing dementia. However, no systematic review has explored the impact of dementia in the prison setting. The objectives of this review were to identify the prevalence of dementia in the prison setting and how prison, health and social care providers assess, diagnose, treat, support and care for prisoners with dementia. A systematic search of the literature from the following databases was undertaken: CINHAL, PubMed, BNI, PsychINFO, and MEDLINE. Search strategies were tailored for each database and included recognised Medical Subject Headings. Hand searching of prominent journals in correctional services and dementia, as well as reference lists of included papers was completed. Open Grey website was searched to identify relevant government, local council and charity publications regarding dementia in the prison setting. The appropriate Critical Appraisal Skills Programmes Checklist for all included studies was completed. Following the application of inclusion and exclusion criteria, 10 studies were included in the review. Due to the nature of the data extracted, a meta-synthesis was not possible; therefore, a thematic synthesis was completed. Three themes emerged: prevalence of dementia in the prison population, identification of older prisoner’s needs, and knowledge of correctional officers and legal professionals. The prevalence and incidence of dementia in prison populations remain largely unknown. There is a need for national policies and local strategies that support a multi-disciplinary approach to early detection, screening and diagnosis of cognitive impairment and dementia across prison settings. Alongside the development of structured prison environments, non-pharmacological interventions, continued assessment of prisoners with a dynamic care plan, and training for health, social and prison staff and prisoners.
