Non-genetic risk and protective factors for sporadic degenerative and vascular young onset dementia

Young onset dementia (with symptom onset before age 65, YOD) has a significant personal and public health impact. Despite this, little is known about its cause and non-genetic factors have been sparsely investigated. Existing studies have not considered the timing or severity of exposure, which is important in late onset dementia (LOD). They have also failed to exclude directly-inherited cases and those occurring secondarily to another disease. This thesis examined the risk for sporadic degenerative and vascular YOD associated with six selected non-genetic factors: cognitive reserve enhancing factors, cardiovascular risk factors, smoking, depression, alcohol use, and traumatic brain injury (TBI). It established the role of exposure timing and severity, as well as interrelationships existing between factors. Data were taken from two epidemiological studies conducted in Sydney, Australia, one of which exclusively included Aboriginal and Torres Strait Islander participants. Dementia diagnosis was confirmed via clinical consensus and risk exposure was retrospectively self- and/or informant-reported. Participants were 96 people with YOD (58.4% with Alzheimer’s disease) and 179 age-group and sex matched control participants. Poor educational attainment, low lifetime participation in cognitive leisure activity, stroke or TIA, smoking, and heavy alcohol use were significantly related to risk for primary degenerative and vascular YOD. Some compensation for low educational attainment was possible via a complex occupation later in life. The effect of hypertension and depression varied depending on when they occurred relative to dementia onset. There was no effect of mild-moderate alcohol use, hypercholesterolemia, diabetes, or TBI of any kind. Cumulative risk exposure was detrimental, particularly where lack of access to or participation in cognitive-reserve enhancing factors clustered with cardiovascular risk factors. The results of this thesis suggest that non-genetic factors have a role in YOD as they do in LOD. Compared with their same-age peers, people with YOD experience a lifetime of disadvantage starting from early in life. The timing and severity of exposure, as well as the potential for compensation with later protective exposures, are important considerations. Efforts to address early life disadvantage and facilitate upward social mobility will be beneficial in delaying dementia to later in life

Single- and double-scattering production of four muons in ultraperipheral PbPb collisions at the Large Hadron Collider

We discuss production of two $\mu^+\mu^-$ pairs in ultraperipheral ultrarelativistic heavy ion collisions at the LHC. We take into account electromagnetic (two-photon) double-scattering production and for a first time direct $\gamma\gamma$ production of four muons in one scattering. We study the unexplored process $\gamma \gamma \to \mu^+\mu^-\mu^+\mu^-$. We present predictions for total and differential cross sections. Measurable nuclear cross sections are obtained and corresponding differential distributions and counting rates are presented.Comment: 13 pages, 11 figures, 1 tabl

What does the general public understand about prevention and treatment of dementia? A systematic review of population-based surveys

Objectives: To synthesise results of population surveys assessing knowledge and attitudes about prevention and treatment of dementia. Methods: MEDLINE, EMBASE, PsycINFO, and grey literature were searched for English language entries published between 2012 and May 2017. Survey questions were grouped using an inductive approach and responses were pooled. Results: Thirty-four eligible studies and four grey literature items were identified. Surveys were conducted in Europe, the US, Eastern Asia, Israel, and Australia. Nearly half of respondents agreed that dementia is a normal and non-preventable part of ageing, but belief in the potential for prevention may be improving over time. The role of cardiovascular risk factors was poorly understood overall. Less than half of respondents reported belief in the availability of a cure for dementia. The value of seeking treatment was highly endorsed. Conclusions: Results suggest that knowledge about the potential for dementia prevention and treatment remains poor but may be improving over time. Knowledge among those living in low- and middle-income countries are largely unknown, presenting challenges for the development of National action plans consistent with World Health Organization directives.Monica Cations, Gorjana Radisic, Maria Crotty, Kate E.

Rehabilitation in dementia care

The Accepted Manuscript (AM) is the final draft author manuscript, as accepted for publication by a journal, including modifications based on referees’ suggestions, before it has undergone copyediting, typesetting and proof correction. This is sometimes referred to as the post-print version. © The Author 2017. Published by Oxford University Press on behalf of the British Geriatrics Society.All rights reserved. For permissions, please email: [email protected] rehabilitation is increasingly accepted as valuable in the management of chronic disease. Whereas traditional rehabilitation models focussed on recovery, maintaining independence and delaying functional decline are now considered worthwhile aims even where full recovery is not feasible. Despite this, rehabilitation is notably absent from dementia care literature and practice. People with dementia report frustration with the lack of availability of structured post-diagnosis pathways like those offered for other conditions. Alternative terms such as ‘re-ablement’ are used to refer to rehabilitation-like services, but lack an evidence-base to guide care. This commentary will discuss possible reasons for the resistance to accept multidisciplinary rehabilitation as part of dementia care, and identifies the value of doing so for people with dementia, their families, and for health professionals

Delivering Trauma-Informed Care in a Hospital Ward for Older Adults With Dementia: An Illustrative Case Series

IntroductionUp to 70% of older adults have experienced a psychologically traumatic event in their life. Traumatic events can have lifelong effects on functioning and emotion regulation and can affect behavior and experiences in care settings. Common healthcare practices and environments can be re-traumatizing for trauma survivors. These features may trigger behavior change (e.g., aggression and agitation) particularly after the onset of dementia. However, very little research exists to understand how the effects of traumatic events manifest in aged care settings. Trauma-informed care is a framework in which the potential impact of trauma is acknowledged, and practices and procedures are adapted to maximize feelings of control and safety for the patient. Trauma-informed care is an innovative approach with little published evidence in acute geriatric settings.MethodsWe present a series of cases to demonstrate how psychological trauma can affect the experience of inpatient care for older people. The cases detail the patients' relevant background, triggers and behaviors followed by the steps taken by staff to support the patient and respond to their trauma-related needs. These cases describe how the principles of trauma-informed care can be applied to recognize when past psychologically traumatic events are impacting the older adult in hospital. The outcomes of these interventions are reported on in terms of their impact on challenging behavior, patient experiences and satisfaction with care, and/or staff confidence and skill.FindingsA range of past events negatively impacted the patients during their time in hospital, including childhood abuse, military service, and domestic violence. Staff implemented strategies to accommodate trauma-related needs while providing care that improved safety and reduced patient distress. Principles of trauma-informed care were applied where able, including providing choices and enabling autonomy. However, organizational and environmental features of inpatient wards continued to pose risks for re-traumatisation.ConclusionsTrauma-informed care is an under-utilized yet potentially beneficial approach to care for older adults in the hospital setting. The cases detailed here demonstrated that the impact of psychological trauma requires an individualized response from staff which when effectively implemented can promote staff and patient safety, reduce the risk of re-traumatisation, and minimize adverse events

Costs and economic evaluations of Quality Improvement Collaboratives in healthcare: a systematic review

BACKGROUND:In increasingly constrained healthcare budgets worldwide, efforts to improve quality and reduce costs are vital. Quality Improvement Collaboratives (QICs) are often used in healthcare settings to implement proven clinical interventions within local and national programs. The cost of this method of implementation, however, is cited as a barrier to use. This systematic review aims to identify and describe studies reporting on costs and cost-effectiveness of QICs when used to implement clinical guidelines in healthcare. METHODS:Multiple databases (CINAHL, MEDLINE, PsycINFO, EMBASE, EconLit and ProQuest) were searched for economic evaluations or cost studies of QICs in healthcare. Studies were included if they reported on economic evaluations or costs of QICs. Two authors independently reviewed citations and full text papers. Key characteristics of eligible studies were extracted, and their quality assessed against the Consolidated Health Economic Evaluation Reporting Standards (CHEERS). Evers CHEC-List was used for full economic evaluations. Cost-effectiveness findings were interpreted through the Johanna Briggs Institute 'three by three dominance matrix tool' to guide conclusions. Currencies were converted to United States dollars for 2018 using OECD and World Bank databases. RESULTS:Few studies reported on costs or economic evaluations of QICs despite their use in healthcare. Eight studies across multiple healthcare settings in acute and long-term care, community addiction treatment and chronic disease management were included. Five were considered good quality and favoured the establishment of QICs as cost-effective implementation methods. The cost savings to the healthcare setting identified in these studies outweighed the cost of the collaborative itself. CONCLUSIONS:Potential cost savings to the health care system in both acute and chronic conditions may be possible by applying QICs at scale. However, variations in effectiveness, costs and elements of the method within studies, indicated that caution is needed. Consistent identification of costs and description of the elements applied in QICs would better inform decisions for their use and may reduce perceived barriers. Lack of studies with negative findings may have been due to publication bias. Future research should include economic evaluations with societal perspectives of costs and savings and the cost-effectiveness of elements of QICs.

How, why and under what circumstances does a quality improvement collaborative build knowledge and skills in clinicians working with people with dementia? A realist informed process evaluation

In increasingly constrained health and aged care services, strategies are needed to improve quality and translate evidence into practice. In dementia care, recent failures in quality and safety have led the WHO to prioritise the translation of known evidence into practice. While quality improvement collaboratives have been widely used in healthcare, there are few examples in dementia care. We describe a recent quality improvement collaborative to improve dementia care across Australia and assess the implementation outcomes of acceptability and feasibility of this strategy to translate known evidence into practice. A realist-informed process evaluation was used to analyse how, why and under what circumstances a quality improvement collaborative built knowledge and skills in clinicians working in dementia care. This realist-informed process evaluation developed, tested and refined the programme theory of a quality improvement collaborative. Data were collected pre-intervention and post-intervention using surveys and interviews with participants (n=28). A combined inductive and deductive data analysis process integrated three frameworks to examine the context and mechanisms of knowledge and skill building in participant clinicians. A refined program theory showed how and why clinicians built knowledge and skills in quality improvement in dementia care. Six mechanisms were identified: motivation, accountability, identity, collective learning, credibility and reflective practice. These mechanisms, in combination, operated to overcome constraints, role boundaries and pessimism about improved practice in dementia care. A quality improvement collaborative designed for clinicians in different contexts and roles was acceptable and feasible in building knowledge, skills and confidence of clinicians to improve dementia care. Supportive reflective practice and a credible, flexible and collaborative process optimised quality improvement knowledge and skills in clinicians working with people with dementia.Lenore de la Perrelle, Monica Cations, Gaery Barbery, Gorjana Radisic, Billingsley Kaambwa, Maria Crotty, Janna Anneke Fitzgerald, Susan Kurrle, Ian Cameron, Craig Whitehead, Jane Thompson, Kate Lave

Primary, allied health, geriatric, pain and palliative healthcare service utilisation by aged care residents, 2012-2017.

OnlinePublObjectives To examine the incidence and trends in primary care, allied health, geriatric, pain and palliative care service use by permanent residential aged care (PRAC) residents and the older Australian population. Methods Repeated cross-sectional analyses on PRAC residents (N = 318,484) and the older (≥65 years) Australian population (N ~ 3.5 million). Outcomes were Medicare Benefits Schedule (MBS) subsidised primary care, allied health, geriatric, pain and palliative services between 2012-13 and 2016-17. GEE Poisson models estimated incidence rates and incidence rate ratios (IRR). Results In 2016-17, PRAC residents had a median of 13 (interquartile range [IQR] 5-19) regular general medical practitioner (GP) attendances, 3 (IQR 1-6) after-hours attendances and 5% saw a geriatrician. Highlights of utilisation changes from 2012-13 to 2016-17 include the following: GP attendances increased by 5%/year (IRR = 1.05, 95% confidence interval [CI] 1.05-1.05) for residents compared to 1%/year (IRR = 1.01, 95%CI 1.01-1.01) for the general population. GP after-hours attendances increased by 15%/year (IRR = 1.15, 95%CI 1.14-1.15) for residents and 9%/year (IRR = 1.08, 95%CI 1.07-1.20) for the general population. GP management plans increased by 12%/year (IRR = 1.12, 95%CI 1.11-1.12) for residents and 10%/year (IRR = 1.10, 95%CI 1.09-1.11) for the general population. Geriatrician consultations increased by 28%/year (IRR = 1.28, 95%CI 1.27-1.29) for residents compared to 14%/year (IRR = 1.14, 95%CI 1.14-1.15) in the general population. Conclusions The utilisation of most examined services increased in both cohorts over time. Preventive and management care, by primary care and allied health care providers, was low and likely influences the utilisation of other attendances. PRAC residents' access to pain, palliative and geriatric medicine services is low and may not address the residents' needs.Maria C.
