Enhancing diabetes care for the most vulnerable in the 21st century: Interim findings of the National Advisory Panel on Care Home Diabetes (NAPCHD).

Older adults with diabetes may carry a substantial health burden in Western ageing societies, occupy more than one in four beds in care homes, and are a highly vulnerable group who often require complex nursing and medical care. The global pandemic (COVID-19) had its epicentre in care homes and revealed many shortfalls in diabetes care resulting in hospital admissions and considerable mortality and comorbid illness. The purpose of this work was to develop a national Strategic Document of Diabetes Care for Care Homes which would bring about worthwhile, sustainable and effective quality diabetes care improvements, and address the shortfalls in care provided. A large diverse and multidisciplinary group of stakeholders (NAPCHD) defined 11 areas of interest where recommendations were needed and using a subgroup allocation approach were set tasks to produce a set of primary recommendations. Each subgroup was given 5 starter questions to begin their work and a format to provide responses. During the initial phase, 16 key findings were identified. Overall, after a period of 18 months, 49 primary recommendations were made, and 7 major conclusions were drawn from these. A model of community and integrated diabetes care for care home residents with diabetes was proposed, and a series of 5 'quick-wins' were created to begin implementation of some of the recommendations that would not require significant funding. The work of the NAPCHD is ongoing but we hope that this current resource will help leaders to make these required changes happen.

Intracranial pressure directly predicts headache morbidity in idiopathic intracranial hypertension.

OBJECTIVE: Headache is the predominant disabler in idiopathic intracranial hypertension (IIH). The aim was to characterise headache and investigate the association with intracranial pressure. METHODS: IIH:WT was a randomised controlled parallel group multicentre trial in the United Kingdom investigating weight management methods in IIH. Participants with active IIH (evidenced by papilloedema) and a body mass index (BMI) ≥35 kg/m2 were recruited. At baseline, 12 months and 24 months headache characteristics and quality of life outcome measures were collected and lumbar puncture measurements were performed. RESULTS: Sixty-six women with active IIH were included with a mean age of 32.0 years (SD ± 7.8), and mean body mass index of 43.9 ± 7.0 kg/m2. The headache phenotype was migraine-like in 90%. Headache severity correlated with ICP at baseline (r = 0.285; p = 0.024); change in headache severity and monthly headache days correlated with change in ICP at 12 months (r = 0.454, p = 0.001 and r = 0.419, p = 0.002 respectively). Cutaneous allodynia was significantly correlated with ICP at 12 months. (r = 0.479, p < 0.001). Boot strap analysis noted a positive association between ICP at 12 and 24 months and enabled prediction of both change in headache severity and monthly headache days. ICP was associated with significant improvements in quality of life (SF-36). CONCLUSIONS: We demonstrate a positive relationship between ICP and headache and cutaneous allodynia, which has not been previously reported in IIH. Those with the greatest reduction in ICP over 12 months had the greatest reduction in headache frequency and severity; this was associated with improvement of quality of life measures. TRIAL REGISTRATION: This work provides Class IIa evidence of the association of raised intracranial pressure and headache. ClinicalTrials.gov number, NCT02124486 .

Clinical guidelines for type 1 diabetes mellitus with an emphasis on older adults: an Executive Summary.

We present a summary of a guideline produced by an international group of experts for managing type 1 diabetes in adults with an emphasis on the special needs of older people with this condition. The rationale for delivering high-quality diabetes care for adults with type 1 diabetes, why it is important to include older people in our considerations, and the key underpinning principles of the guideline are included. The structure of the recommendations given is described and consists of 'general' recommendations followed by 'specific' recommendations according to three categories depending on the characteristics of adults addressed, such as functional level or self-management ability. Recommendations are provided in the areas of: clinical diagnosis, establishing management plans and glucose regulation, diabetes self-management education, nutritional therapy, physical activity, exercise and lifestyle modification, insulin treatments and regimens, use of technology in diabetes management, hypoglycaemia, managing cardiovascular risk, management of microvascular risk, and inpatient management of type 1 diabetes and ketoacidosis.

Joint British Diabetes Societies for Inpatient Care (JBDS-IP) Clinical Guideline Inpatient care of the frail older adult with diabetes: an Executive Summary.

We present an Executive Summary of a guideline produced by a Joint British Diabetes Societies for Inpatient Care Writing Group for managing frail older inpatients with diabetes. This represents a multidisciplinary stakeholder consensus document providing more than 100 recommendations in eight areas: functional assessment and detection of frailty; preventative care: assessing risk factors and avoiding hospital admissions; general inpatient management principles; managing therapy choices for the frail older inpatient with diabetes; managing associated comorbidities and concerns; pre-operative assessment and care; discharge planning and principles of follow-up; and end of life care. The document is intended to guide effective clinical decision-making in an inpatient setting and is supported by four appendices: Appendix 1, STOPPFRAIL criteria; Appendix 2, Acute care toolkit 3-Royal College of Physicians; Appendix 3, a description of physical performance and frailty measures for routine NHS application; and Appendix 4, Inpatient Frailty Care Pathway-template. This document is expected to enhance clinical outcomes and overall health status for this vulnerable inpatient population of older people with diabetes. The full version of the guideline, including the appendices, can be found at https://abcd.care/sites/abcd.care/files/resources/Inpatient_Care_of_the_Frail_Older_Adult.pdf.

European Headache Federation recommendations for neurologists managing giant cell arteritis.

BACKGROUND AND AIM: Giant cell arteritis (GCA) remains a medical emergency because of the risk of sudden irreversible sight loss and rarely stroke along with other complications. Because headache is one of the cardinal symptoms of cranial GCA, neurologists need to be up to date with the advances in investigation and management of this condition. The aim of this document by the European Headache Federation (EHF) is to provide an evidence-based and expert-based recommendations on GCA. METHODS: The working group identified relevant questions, performed systematic literature review and assessed the quality of available evidence, and wrote recommendations. Where there was not a high level of evidence, the multidisciplinary (neurology, ophthalmology and rheumatology) group recommended best practice based on their clinical experience. RESULTS: Across Europe, fast track pathways and the utility of advanced imaging techniques are helping to reduce diagnostic delay and uncertainty, with improved clinical outcomes for patients. GCA is treated with high dose glucocorticoids (GC) as a first line agent however long-term GC toxicity is one of the key concerns for clinicians and patients. The first phase 2 and phase 3 randomised controlled trials of Tocilizumab, an IL-6 receptor antagonist, have been published. It is now been approved as the first ever licensed drug to be used in GCA. CONCLUSION: The present article will outline recent advances made in the diagnosis and management of GCA.

Evidence-based diabetes care for older people with Type 2 diabetes: a critical review.

In our ageing society diabetes imposes a significant burden in terms of the numbers of people with the condition, diabetes-related complications including disability, and health and social care expenditure. Older people with diabetes can represent some of the more complex and difficult challenges facing the clinician working in different settings, and the recognition that we have only a relatively small (but increasing) evidence base to guide us in diabetes management is a limitation of our current approaches. Nevertheless, in this review we attempt to explore what evidence there is to guide us in a comprehensive scheme of treatment for older adults, often in a high-risk clinical state, in terms of glucose lowering, blood pressure and lipid management, frailty care and lifestyle interventions. We strive towards individualized care and make a call for action for more high-quality research using different trial designs.

Cognitive Frailty in Older People with Type 2 Diabetes Mellitus: the Central Role of Hypoglycaemia and the Need for Prevention.

PURPOSE OF REVIEW: To highlight the central role of hypoglycaemia in the causation of cognitive frailty and explore ways of recognition and prevention of hypoglycaemia. RECENT FINDINGS: Cognitive frailty is an emerging new concept defined as the concomitant presence of physical frailty and cognitive impairment. In older people with diabetes, cognitive frailty is associated with an increased risk of mortality greater than from either physical frailty or cognitive impairment alone. Hypoglycaemia is directly associated with increased risk of cognitive impairment and physical frailty which are the two components of cognitive frailty. The incidence of hypoglycaemia in older people with diabetes is rising and hypoglycaemia-related hospitalisation has overtaken that of hyperglycaemia. Recognition of hypoglycaemic episodes in old age remains challenging which leads to misdiagnoses and under-reporting. Therefore, hypoglycaemia prevention strategies are needed. Research is still required to investigate whether prevention of hypoglycaemia would lead to a reduction in the incidence of cognitive frailty.

Failing to meet the needs of generations of care home residents with diabetes: a review of the literature and a call for action.

In residential care homes and aged-care facilities globally, between one in three and one in four residents may have diabetes, an often complex highly co-morbid illness that leads to frailty, dependency, disability and reduced life expectancy. Residents with diabetes also have a high risk of hypoglycaemia, avoidable hospital admissions, and represent one of the most difficult challenges to health professionals and care staff in optimizing their diabetes and medical care. This detailed review examines the literature relating to care home diabetes over the last 25 years to assess what has been achieved in characterizing residents with diabetes, and what we know about the various but limited intervention studies that have been carried out internationally. The guidance and guidelines that have been published to assist clinicians in planning effective and safe care for this rather vulnerable group of people with diabetes are also reviewed. The review presents the first diagrammatic representation of a likely physiological cascade depicting the mainly irreversible functional decline a resident with diabetes might experience, provides modern principles of care for each resident with diabetes, and identifies what priority recommendations are required to be implemented if diabetes care is to improve. The review concludes that action is required since diabetes care still remains fragmented, sub-optimal, and in need of investment, otherwise care home residents with diabetes will continue to have their needs unfulfilled.

Type 2 diabetes mellitus in older people: a brief statement of key principles of modern day management including the assessment of frailty. A national collaborative stakeholder initiative.

Rates of population ageing are unprecedented and this, combined with the progressive urbanization of lifestyles, has led to a dramatic shift in the epidemiology of diabetes towards old age, particularly to those aged 60-79 years. Both ageing and diabetes are recognized as important risk factors for the development of functional decline and disability. In addition, diabetes is associated with a high economic, social and health burden. Traditional macrovascular and microvascular complications of diabetes appear to account for less than half of the diabetes-related disability observed in older people. Despite this, older adults are under-represented in clinical trials. Guidelines from organizations such as the National Institute for Health and Care Excellence (NICE), the European Association for the Study of Diabetes, and the American Diabetes Association acknowledge the need for individualized care, but the glycaemic targets that are suggested to constitute good control [HbA1c 53-59 mmol/mol (7-7.5%)] are too tight for frail older individuals. We present a framework for the assessment of older adults and guidelines for the management of this population according to their frailty status, with the intention of reducing complications and improving quality of life for these people.

Examining factors associated with excess mortality in older people (age ≥ 70 years) with diabetes - a 10-year cohort study of older people with and without diabetes.

AIMS: To compare all-cause mortality in older people with or without diabetes and consider the associated risk of comorbidity and polypharmacy. METHODS: A 10-year cohort study using data from the Health Innovation Network database (2003-2013) comparing mortality in people aged ≥ 70 years with diabetes (DM cohort) (n = 35 717) and without diabetes (No DM cohort) (n = 307 918). RESULTS: The mean age of the DM cohort was 78.1 ± 5.8 years vs. 79.0 ± 6.3 years in the No DM cohort. Mean diabetes duration was 8.2 ± 8.1 years, and 30% had diabetes for > 10 years. The DM cohort had a greater comorbidity load and people in this cohort were prescribed more therapies than the No DM cohort. The 5- and 10-year survival rates were lower in the DM cohort at 64% and 39%, respectively, compared with 72% and 50% in the No DM cohort. The excess mortality in the DM cohort was greatest in those aged < 75 years with longer duration diabetes, the relative hazard for mortality was higher in females. Although comorbidity and polypharmacy were associated with increased mortality risk in the DM cohort, this risk was lower compared with the No DM cohort. The hazard ratios (95% confidence interval) for comorbidities > 4 and medicines ≥ 7 were 1.29 (1.19 to 1.41) and 1.34 (1.25 to 1.43) in the DM cohort and 1.63 (1.57 to 1.70) and 1.48 (1.40 to 1.56) in the No DM cohort, respectively. CONCLUSIONS: There is significant excess mortality in older people with diabetes, which is unexplained by comorbidity or polypharmacy. This excess is greatest in the younger old with longer disease duration, suggesting that it may be related to the effect of diabetes exposure.

Diabetes and dementia in older people: a Best Clinical Practice Statement by a multidisciplinary National Expert Working Group.

Both dementia and diabetes mellitus are long-term disabling conditions and each may be a co-morbidity of the other. Type 2 diabetes is associated with a 1.5- to 2-fold higher risk of dementia. Diabetes also may occur for the first time in many individuals with mental ill health, including cognitive impairment and dementia, and this may complicate management and lead to difficulties in self-care. Case finding is often poor for cognitive impairment in medical settings and for diabetes in mental health settings and this needs to be addressed in the development of care pathways for both conditions. Many other deficiencies in quality care (both for dementia and diabetes) currently exist, but we hope that this Best Clinical Practice Statement will provide a platform for further work in this area. We have outlined the key steps in an integrated care pathway for both elements of this clinical relationship, produced guidance on identifying each condition, dealt with the potentially hazardous issue of hypoglycaemia, and have outlined important competencies required of healthcare workers in both medical/diabetes and mental health settings to enhance clinical care.

Assessing the impact of diabetes on the quality of life of older adults living in a care home: validation of the ADDQoL Senior.

AIMS: Around a quarter of UK care-home residents have diabetes. Diabetes is known to impact quality of life but existing diabetes-specific quality of life measures are unsuitable for elderly care-home residents. We aimed to develop and evaluate a new measure for use with older adults, to be particularly suitable for use with care-home residents: the Audit of Diabetes-Dependent Quality of Life (ADDQoL) Senior*. METHODS: Content and format changes were made to the 19-domain ADDQoL, informed by related measures for people with visual impairments (12 domain-specific items were retained, four items were revised/added and three items were removed). This revision was modified further following cognitive debriefing interviews with three older adults living in a care home. Psychometric evaluation of the newly developed 17-domain ADDQoL Senior was conducted using data from 90 care-home residents with diabetes who took part in a broader intervention study. RESULTS: The life domains most impacted by diabetes were 'independence' and 'freedom to eat as I wish'. The ADDQoL Senior demonstrated good factor structure and internal consistency (Cronbach's alpha = 0.924). Domain scores were, as expected, significantly intercorrelated. CONCLUSIONS: The ADDQoL Senior measures the perceived impact of diabetes on quality of life in older adults, and has been found to be suitable for those living in care homes if administered by interview. The scale has demonstrated acceptability and excellent psychometric properties. It is anticipated that the number of items may be reduced in the future if our current findings can be replicated.

Diabetes mellitus as a modulator of functional impairment and decline in Alzheimer's disease. The Real.FR cohort.

AIMS: To determine whether diabetes mellitus influences functional status in patients with Alzheimer's disease. METHODS: We studied 608 community-dwelling patients with Alzheimer's disease from a prospective multicenter cohort. Diabetes was assessed at baseline. Functional status was assessed twice yearly with the Activities of Daily Living scale. Each patient had a baseline functional disability if their Activities of Daily Living score was < 6. Progression of functional disability was defined by a decreased Activities of Daily Living score over 4 years of follow-up visits. RESULTS: At baseline, diabetes was present in 63 participants (10.4%) and, compared with those without diabetes, was associated with functional impairment [age- and sex-adjusted OR = 2.73 (95% CI 1.41-5.28)]. After controlling for confounders, the association remained significant [OR = 2.04 (95% CI 1.02-4.11)]. Follow-up demonstrated a significant interaction between duration of Alzheimer's disease and diabetes, which was associated with progression of functional impairment in patients who had been diagnosed with Alzheimer's disease for less than 1 year [age- and sex-adjusted hazard ratio = 1.52 (95% CI 1.01-2.30), P = 0.048], but not in those who had been diagnosed with Alzheimer's disease for more than 1 year [age- and sex-adjusted hazard ratio = 0.78 (95% CI 0.47-1.28), P = 0.32]. Abnormal one-leg balance, polymedication and obesity seem to be important factors explaining the association between diabetes and functional status. CONCLUSIONS: At baseline, the presence of diabetes significantly increases the risk of functional disability in patients with Alzheimer's disease; our longitudinal data confirm that in patients with a recent diagnosis of Alzheimer's disease (but not in those who have had Alzheimer's disease for longer than 1 year), diabetes continues to worsen functional status.

Gender-specific inhibition of platelet aggregation following omega-3 fatty acid supplementation.

BACKGROUND AND AIMS: Increased platelet aggregation is a major risk factor for heart attacks, stroke and thrombosis. Long chain omega-3 polyunsaturated fatty acids (LCn-3PUFA; eicosapentaenoic acid, EPA; docosahexaenoic acid, DHA) reduce platelet aggregation; however studies in the published literature involving EPA and/or DHA supplementation have yielded equivocal results. Recent in vitro studies have demonstrated that inhibition of platelet aggregation by LCn-3PUFA is gender specific. We examined the acute effects of dietary supplementation with EPA or DHA rich oils on platelet aggregation in healthy male and females. METHODS AND RESULTS: A blinded placebo controlled trial involving 15 male and 15 female subjects. Platelet aggregation was measured at 0, 2, 5 and 24 h post-supplementation with a single dose of either a placebo or EPA or DHA rich oil capsules. The relationship between LCn-3PUFA and platelet activity at each time point was examined according to gender vs. treatment. EPA was significantly the most effective in reducing platelet aggregation in males at 2, 5 and 24 h post-supplementation (-11%, -10.6%, -20.5% respectively) whereas DHA was not effective relative to placebo. In contrast, in females, DHA significantly reduced platelet aggregation at 24 h (-13.7%) while EPA was not effective. An inverse relationship between testosterone levels and platelet aggregation following EPA supplementation was observed. CONCLUSION: Interactions between sex hormones and omega-3 fatty acids exist to differentially reduce platelet aggregation. For healthy individuals, males may benefit more from EPA supplementation while females are more responsive to DHA.

Metabolic phenotypes explain the relationship between dysglycaemia and frailty in older people with type 2 diabetes.

BACKGROUND: Dysglycaemia (hyperglycaemia and hypoglycaemia) increase the risk of frailty in older people with diabetes, which appears contradictory. However, the characteristics of patients included in these studies are different and may reflect different metabolic phenotypes of frailty that may explain this apparent contradiction. AIMS: To review the characteristics of frail patients included in clinical studies that reported an association between dysglycaemia and frailty in order to explore whether there is any metabolic differences in the profile of these patients. METHODS: A systematic review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations. Key words around older people, type 2 diabetes mellitus, frailty, hyperglycaemia and low glycaemia were used in the literature search. RESULTS: Only 8 studies met the inclusion criteria. Four studies investigated the risk of frailty associated with low glycaemia. Two studies showed that hypoglycaemia increased the risk of frailty by 44% (HR 1.60, 95% CI 1.14 to 2.42) and predicted greater level of dependency (p < 0.001), respectively. The other two studies reported that HbA1c inversely correlated with clinical frailty scale (r = -0.31, p < 0.01) and HbA1c < 6.0% was associated with increased risk of disability (3.45, 1.02 to 11.6), respectively. Compared with non-frail patients, those with frailty tended to have lower body weight or body mass index (BMI), have features of malnutrition such as low serum albumin or low total cholesterol and suffer from more comorbidities including dementia. Four studies explored the association of high glycaemia with frailty. Higher HbA1c predicted frailty (OR 1.43, 95% CI 1.045 to 1.97) and positively correlated with Edmonton frail score (r = 0.44, p < 0.001), respectively in two studies. The other two studies found that subjects with HbA1c ≥ 6.5% had the greatest prevalence of frailty (70.3%) and subjects with higher HbA1c at baseline to have a higher frailty level throughout later life, respectively. Compared with non-frail patients, those with frailty tended to have higher body weight, waist circumference and BMI. They also have less physical activity, higher cholesterol level and have more comorbidities. CONCLUSIONS: Dysglycaemia increases the risk of frailty but the characteristics of patients in these studies suggest different metabolic phenotypes of frailty. Therefore, these metabolic differences in frailty should be taken into consideration in the management of older people with diabetes.

Discovery and insights from DSX mission's high-power VLF wave transmission experiments in the radiation belts.

Space weather phenomena can threaten space technologies. A hazard among these is the population of relativistic electrons in the Van Allen radiation belts. To reduce the threat, artificial processes can be introduced by transmitting very-low-frequency (VLF) waves into the belts. The resulting wave-particle interactions may deplete these harmful electrons. However, when transmitting VLF waves in space plasma, the antenna, plasma, and waves interact in a manner that is not well-understood. We conducted a series of VLF transmission experiments in the radiation belts and measured the power and radiation impedance under various frequencies and conditions. The results demonstrate the critical role played by the plasma-antenna-wave interaction around high-voltage space antennae and open the possibility to transmit high power in space. The physical insight obtained in this study can provide guidance to future high-power space-borne VLF transmitter developments, laboratory whistler-mode wave injection experiments, and the interpretation of various astrophysical and optical phenomena.

Good clinical practice guidelines for care home residents with diabetes: an executive summary.

A Task and Finish Group of Diabetes UK was convened over 14 months to undertake a systematic review of the original 1999 British Diabetic Association guidance on care home diabetes, incorporate new research findings and produce a set of recommendations that are evidenced-based, practical and implementable within UK care home settings. The anticipation of Diabetes UK is that these guidelines will represent a national policy of good clinical practice for diabetes care within care homes. This executive summary demonstrates how the full guidelines should provide a framework of assessment of the quality of diabetes care within care homes, for use by regulatory bodies who have responsibility for this provision of diabetes care. This document is primarily based on recommendations for adults living within British care home environments and its focus, by virtue of the nature and characteristics of residents, is on older adults. Improvements in diabetes care within residential and nursing homes are likely to follow a sustained commitment by health and social care professionals to ensure that the well-being of residents with diabetes is paramount, that high-quality policies of diabetes care are implemented and monitored and effective diabetes education is a mandatory and integral part of care home staff training.

Diabetes medication patient safety incident reports to the National Reporting and Learning Service: the care home setting.

AIMS: To analyse adverse drug events in older people with diabetes in the care home setting via incident reports obtained from the National Reporting and Learning Service. METHODS: A Freedom of Information request was made to the National Reporting and Learning Service via the National Patient Safety Agency. Within the National Reporting and Learning Service, reports on diabetes within the category of 'medication' using the location limiter of 'hospice or nursing home or residential home' were searched. We requested information about the number and nature of adverse drug event reports that had been received in relation to diabetes. The data were subdivided into reports (1) relating to insulin therapy and (2) oral glucose-lowering agents. RESULTS: Data were collected between 1 January 2005 and 31 December 2009. There were 684 reports related to insulin and 84 incidents related to oral glucose-lowering agents. The most common error category with both types of drug therapy was wrong or unclear dose: 173 reports for insulin, including one death, and 20 reports for oral therapy. CONCLUSIONS: Residents with diabetes in care homes are potentially at risk of harm from adverse drug events pertaining to insulin and oral glucose-lowering agents. Because of under-reporting, our data most likely represent only a fraction of events.

Solid waste management in western Canadian First Nations.

This research examined solid waste management on First Nations communities in western Canada to provide information and insight into programs, practices, policies, and activities, as well as to help bridge an identified gap related to these in the literature. Utilizing a qualitative case study approach, we examined twelve First Nations communities in Canada's western provinces, which relative to other communities, had 'advanced' solid waste management systems in place. Interviews conducted in each of the communities yielded information on six themes grounded in the data, including solid waste facilities and infrastructure, solid waste programs, local capacity, provincial stewardship programs, regulation and enforcement, and funding/finance. Our analysis show that majority of the communities examined are advancing their waste management systems and now have infrastructure/facilities, such as transfer stations and recycling depots, and have implemented recycling programs, which they previously did not have. As well, we learned that implementing such programs has reduced practices, such as open dumping, which the literature highlights as a common way of managing waste in First Nations communities. Most of the communities attributed the success of their programs to regular residential curbside pickups, ability to transport waste out of the community, and community involvement and interest in programs. Despite these improvements, inadequate funding hampers the efforts of communities to sustain and/or expand their programs and maintain facilities. Additionally, most communities face challenges partnering with provincial stewardship programs, and some communities are not clear whether they even qualify to participate in these programs.
