Dementia symptoms develop after brain cells are damaged in areas of the brain that are responsible for memory and behaviour. The major risk factor for dementia is age. Higher blood cholesterol levels in mid-life increase risk for Alzheimer’s disease (AD) in later life. However, lower levels of the cholesterol-carrying high density lipoprotein (HDL) associate with increased risk for AD. HDL is considered “good” because it removes cholesterol from the body. As HDL transports antioxidants, we have investigated whether antioxidant levels are lower in dementia patients, whether this changes the oxidation and affects the efficiency of cholesterol transport from cells by HDL. In this study we found that AD patients with vascular risk factors have low level of HDL and antioxidants and export of cholesterol to HDL is lower than in healthy control subjects of the same age. This study suggests the importance of improving micro- and macro-nutrient status in older adults.

Alzheimer's disease (AD) is the most common form of dementia affecting around 36 million people worldwide. The symptoms of the disease are associated with well-characterised patterns of damage in the brain. In addition, metabolic changes in the brains of AD patients, particularly abnormalities in the way the brain utilises sugars such as glucose have been identified decades before these symptoms appear. It is impossible to study such changes in the cells of living patients, and it is difficult to adequately study the disease in animals as they do not naturally develop the condition. Our technique uses human stem cells, that can be turned into brain cells to generate functional models of the brain. Generating functional brain models from these cells will allow us to study AD induced metabolic changes in order to determine how changes in the metabolism of these cells will lead to the neurodegeneration observed in AD.

This article reports an evaluation of the NHS Health Check in an area of Birmingham. The NHS Health Check is available for anyone aged 40-74 and assesses their risk of cardiovascular diseases including heart disease, stroke, diabetes and kidney disease. It also helps provide support for people who need to make lifestyle changes to help reduce their risk to these conditions. This is particularly relevant to people as they get older because our risk to cardiovascular disease increases as we age.

The NHS Health Check was designed by UK Department of Health to address increased prevalence of cardiovascular disease by identifying risk levels and facilitating behaviour change. It constituted biomedical testing, personalised advice and lifestyle support. The objective of the study was to explore Health Care Professionals’ (HCPs) and patients’ experiences of delivering and receiving the NHS Health Check in an inner-city region of England.
Patients and HCPs in primary care were interviewed using semi-structured schedules. Data were analysed using Thematic Analysis.
Four themes were identified. Firstly, Health Check as a test of ‘roadworthiness’ for people. The roadworthiness metaphor resonated with some patients but it signified a passive stance toward illness. Some patients described the check as useful in the theme, Health check as revelatory. HCPs found visual aids demonstrating levels of salt/fat/sugar in everyday foods and a ‘traffic light’ tape measure helpful in communicating such ‘revelations’ with patients. Being SMART and following the protocol revealed that few HCPs used SMART goals and few patients spoke of them. HCPs require training to understand their rationale compared with traditional advice-giving. The need for further follow-up revealed disparity in follow-ups and patients were not systematically monitored over time.
HCPs’ training needs to include the use and evidence of the effectiveness of SMART goals in changing health behaviours. The significance of fidelity to protocol needs to be communicated to HCPs and commissioners to ensure consistency. Monitoring and measurement of follow-up, e.g., tracking of referrals, need to be resourced to provide evidence of the success of the NHS Health Check in terms of healthier lifestyles and reduced CVD risk.
Older drivers who lack confidence on the road could benefit from a new training plan being developed by researchers at Aston University.
The project will target older drivers’ ability to pay attention to different locations when moving at speed – known as their ‘attentional switching flexibility’. As people age, this ability, essential for safe driving, can slow down, with serious implications for drivers and others on the road. Although older drivers are reported to have fewer collisions and pose a lower safety risk to other road users than other age groups, it is known they are much more likely to suffer from a lack of attentional switching flexibility, which can severely affect their confidence. Aston researchers believe the extra time it takes older people to shift their attention from one thing to another may be a major source of this problem, and have developed a new training plan to tackle the issue. A team, led by Dr Carol Holland, Director of the Aston Research Centre for Healthy Ageing at Aston University’s School of Life and Health Sciences, will test participants with a series of visual prompts designed to gradually increase the speed at which they can focus their attention. They will then be placed in a driving simulator and asked to tackle difficult traffic situations such as at virtual roundabouts and road intersections. Their performance on the simulator will be measured over a period of time to assess the degree of their improvement. Dr Holland said: “Many older drivers give up driving because of concerns about their safety and a general loss of confidence on the road. We hope to be able to keep them on the road for longer because they tend not to be bad drivers at all – far from it. The issue is one of confidence; if this can be built up through a specifically-designed training programme such as the one we are developing, it will improve the safety not only of older drivers, but of other road users as well. “No one has studied the impact of attentional switching costs on the proficiency of older drivers before. We want to change the untrue stereotype of older drivers as unsafe and help enable them to feel more confident and competent on the road.” Delaying the point when people give up driving could have significant general health benefits. Early driver cessation is often a precursor of depression and isolation. Loss of independent mobility is also associated with ‘life space constriction’, which is linked to frailty and loss of independence. It is also known that maintaining or increasing the proportion of older drivers on the roads in any area or region has a positive influence on the road transport environment and overall incident frequency. A recent RAC study estimated that of the 500,000 drivers who turned 70 in 2013 in the UK, 170,000 of them will give up driving before they need to. The project is part funded by the Rees Jeffreys road fund as a PhD studentship and will be conducted in collaboration with Professor Klaus Kessler of the Aston Brain Centre.

Paper published in the Journal of Materials Chemistry B Bioactive Organic-Inorganic Hybrids with Improved Mechanical Performance
Human tissue including both soft tissue (e.g. skin) and hard tissue (e.g. bones) are continuously remodelled and regenerated throughout our lifetime. However, as we age our bodies’ ability to repair and regenerate significantly reduces. Healing in older adults can be particularly slow due to reduced cellular activity. As we age our bones become brittle and weaker and reduced bone density can be problematic for post-menopausal women. Consequently bone is the most widely transplanted material with the exception of blood. It is therefore very important to develop new and improved biomaterials for bone regeneration. Effective implant biomaterials can help tissue regenerate and significantly improve the quality of life of older adults in later life. Recently there has been a change in philosophy moving away from traditional materials (e.g. large metal plates that are inserted for life) towards developing new smart biomaterials that can help the body self-heal and eventually become absorbed and replaced by the body. Solid glass particles containing calcium and phosphorous (the main building blocks of bone) are now used widely clinically to treat small bone defects (e.g. orthopaedic bone grafting in non-load bearing sites, ossicular replacement, head and neck surgery, tooth root implants). The latest drive is to mimic nature by developing highly porous scaffolds which enhance blood flow and cell ingrowth to increase the rate of healing. However these materials are usually mechanically weak. Dr Richard Martin (ARCHA & EAS) in collaboration with colleagues at the Chinese Academy of Science have developed novel sol-gel polymer hybrids for bone replacement applications with vastly improved mechanical properties whilst still maintaining this porosity. A key feature of this work was ensuring that the organic and inorganic phases are strongly bonded together to stop the polymer from rapidly washing out from the hybrid which would reduce the strength. The work was recently published in the Journal of Materials Chemistry B; full details can be found at http://pubs.rsc.org/en/content/articlelanding/2014/tb/c4tb01776e#!divAbstract
