COVID-19-Study of Immune Responses Following Vaccination Against SARS-CoV-2

T-cell adaptive immunity is known to be required to sustain a long term immunoglobulin production and a long term memory against several infections. Previous results suggest a lack in the generation of T-cell responses against CoV-N, M and S proteins among cancer patients exposed to SARS-CoV-2 virus highlighting that cancer patients failed to mount a protective T-cell immunity. Given this context, our hypothesis is that COVID-19 vaccine candidates are not immunogenic in some cancer patients. Thus, the monitoring of CD4 and CD8 T-cell responses before and after vaccination might provide information related to the correlation between induction of CD4 T-cells (including helper follicular T-cells) by the vaccine and long-term IgG production (serological index). Additionally, the failure of COVID-19 vaccines in some patients should be monitor carefully in order to provide specific recommendations to avoid COVID-19 infections. The main objective is to assess humoral immune responses following COVID-19 vaccination in a population of cancer patients.

The Everyday Function Intervention Trial

Loss of independence, cognitive decline, and difficulties in everyday function are areas of great concern for older adults and their families. From a public health perspective, successful efforts that enable older adults to age within their homes, as compared to nursing homes, will save an estimated $80 billion dollars per year. Cognitive training is one intervention that maintains cognition, everyday function, and health. Although clearly an important and effective intervention, the mediators, or mechanisms, underlying this program are unknown. Our overall objective is to assess the cognitive and psychosocial factors within daily life that account for the transfer of one form of cognitive training to everyday function. This exploratory double-blind trial will randomize older adults to 20 hours of cognitive training or cognitively stimulating activities. The investigators will assess cognitive and psychosocial factors before, during, and after training within daily life. The investigators will then compare such factors and assess how they impact the transfer of cognitive training to everyday functioning. The investigators will also include an eligible sub group of the EFIT participants who will have functional MRI brain scans and sleep evaluation using the Sleep Profiler, a clinically approved device, at pre and post brain training. The investigators will also monitor daily activity in this sub group using FitBIt watches. Our central hypothesis is that improvements in daily processing speed and attention, key components of higher order cognitive functions, will have the strongest relationship with everyday function changes. This exploratory study is the first of its kind and will be used to provide important data relevant to a future larger randomized controlled trial examining mediators of cognitive training in a representative sample of adults. Additionally, all data collection, with the exception of MRI, can be completed remotely within the participant's home. This information will assist in the future development of more effective home- and community-based interventions that maintain everyday function.

Dementia Risk and Dynamic Response to Exercise

Research suggests that physical exercise supports brain health and cognition as we age. The goal of this project is to examine the specific changes in brain blood flow and biological factors in the blood immediately after exercise in older adults who have the APOE4 gene, a genetic risk factor for developing Alzheimer's. Results from this study will help researchers and clinicians understand and measure changes in the body and brain as a function of exercise, and how those changes relate to Alzheimer's risk.

INNOVATEDIGNITY: Co-designing Digital Health Technologies With Older People in Homecare Settings.

One of the crucial components of successful ageing is to live independently in old age. Yet in UK alone, nearly 300000 older people require assistance with 3 or more essential daily tasks like eating, bathing and mobility which compromises on their independent living. Additionally, in a crisis where health system in UK is already overstretched to its resources to combat the recent Coronavirus Disease 2019 (COVID-19) pandemic, allocating resources for regular homecare services has become challenging. In this situation, Digital Health Technologies (DHTs) can be a potential solution to promote healthy ageing, support psycho-social wellbeing and enhance independent living for older people. Such technologies comprise a wide range of products used in the health and care services including apps, software and online platforms to benefit people. Yet DHTs are barely adopted by older people as they do not reflect their actual user needs leading to poor appropriation of DHTs in homecare settings. The investigators aim to address this gap by involving older people living at the Leach Court, UK under the eco system of the Brighton & Hove Digital Health Living Lab (BHLL) to co-design with us DHTs that addresses the barriers & facilitators they face in adopting to DHTs. This participatory research approach has a qualitative study design which is sensitive to basic human values like 'dignity', appreciates that older people are 'expert of their experiences' and methodologically has phenomenological underpinnings gathering the researcher's understanding from the lived experiences of older people. This unique project, part of the European Union (EU) Horizon 2020 funded INNOVATEDIGNITY project, will be aiming to translate intangible human values like 'dignity' into tangible technology design through better understanding of the barriers & facilitators older people face to DHTs adoption. With global population of older people increasing faster than all other age groups currently, this project stands to meet the future demands of the ageing population through dignity sensitive better designed DHTs . This project is part of the Marie Sk?odowska-Curie Actions (MSCA) Innovative Training Networks (ITN). This project has received funding from the European Union's H2020-MSCA-ITN-2018 programme under grant agreement No 813928.

Combined Exercise Trial

The number of older Americans will double in the next 4 decades to nearly 90 million, placing an unprecedented financial and resource burden on the health care system. Exercise has clear and demonstrable physical benefits, but a more precise understanding of how exercise supports cognitive function is essential. Demonstrating definitively that exercise as recommended by public health entities has benefits for cognition would have enormous public health implications, encourage the public to adapt more active lifestyles, and stimulate the development of effective exercise delivery programs.

Modulating Prospective Memory in Older Adults With Non-invasive Brain Stimulation

Prospective memory is the ability to remember to carry out intentions with a certain delay (e.g. remember to buy stamps when passing a postal office). Prospective memory tasks require a large degree of self-initiated retrieval and in the absence of a prompt to recall, people must 'remember to remember' by their own volition. Thus, prospective memory is a challenge - especially in old age with increasing health-related prospective memory demands. Previous studies reported links between neural activity in specific brain regions and prospective memory performance. Yet, the mere occurrence of a change in brain activity in concomitance with performance of a behavioral task is not sufficient to confirm a causal relationship between the two phenomena. Therefore, this study aims to apply non-invasive brain stimulation to facilitate or inhibit activity in different brain regions presumed to be functionally associated with prospective memory. Additional to the prospective memory tasks, the investigators will implement control tasks (i.e., attention) to assess whether stimulation will specifically enhance prospective memory performance or whether other cognitive functions will be modulated additionally. It is hypothesized that stimulation will lead to changes in prospective memory functioning. Further, the investigators expect that facilitation of attentional processes might be linked to prospective memory improvements.

Modulating the Locus Coeruleus Function

The purpose of this study is to investigate the impact of transcutaneous vagus nerve stimulation (tVNS) on specific brain regions involved in memory and attention processes. tVNS is a non-invasive and non-pharmacological technique known for targeting the locus coeruleus, a small subcortical nucleus in the brain thought to be involved in the earliest stages of Alzheimer's disease. This nucleus also plays a role in numerous cognitive functions, comprising memory and attention.

SHARE(D) Stage II: Alzheimer's Risk Disclosure Protocol Piloting

The goal of this study is to test efficacy and safety of person-centered, culturally-informed protocols for disclosure of different combinations of Alzheimer's dementia risk factors. Building on the results from a federally-funded assessment of preferences and needs of racially diverse participants and their respective friends/family members, in regard to Dementia - Alzheimer's Type, we have produced protocols for communication of DAT risk, with attention to specific adaptations in style or content based on individual factors and preferences. These protocols allow for communication of risk based on clinical history and diagnosis, structural neuroimaging, apolipoprotein-E status, and amyloid and tau burden on positron emission tomography. In particular, protocols specify (a) effective methods of communicating risk conferred by each data source, (b) information designed for patients versus informants, (c) psychoeducation needs, and (d) resource/support needs. We will recruit a randomly-selected subset of 10 dyads (including 5 participants who are Non-Hispanic African-American, 5 participants who are Non-Hispanic White) from the Stage I sample to whom we will develop and implement personalized DAT risk disclosure protocols. We will provide preliminary information on the effectiveness of these protocols in terms of patient/co-participant comprehension and recall of feedback provided, satisfaction with the content and format of feedback, and initial changes in mood or behavior immediately following and shortly after risk disclosure sessions.

The Nicotinic Cholinergic System and Cognitive Aging

Prior research has shown that a chemical system in the brain called the cholinergic system is primarily responsible for cognitive symptoms seen in people with dementia. While therapeutic benefits are clear in dementia, what remains uncertain is the role that the cholinergic system in general and a subset of receptors called the nicotinic system plays in cognition in healthy non-demented older adults (referred to as normal cognitive aging). This is critical because the ever growing healthy aging population will show declines in cognition that fall short of dementia but still impact functional abilities and independence. Maintaining good nicotinic system functioning throughout adulthood may lessen the cognitive symptoms of aging. At this time, it is not clear what the biological cause of age-related changes in cognition is. This study will examine the role of the nicotinic system in the healthy aging brain and examine its role in memory and thinking processes in older and younger adults.

Signal Propagation and Its Relationship to Cognitive Performance in the Aging Human Brain (Focus or Spread)

In the next three decades, the world's population over 60 years old is expected to more than double its size. Even in the absence of an obvious pathology (i.e., healthy aging), advancing age is typically associated with a progressive decline in cognitive performance. Although pathophysiological changes in age-related neurodegenerative disorders have received much attention over the past years, far less is known about the neural processes affecting cognition in healthy ageing. One of these postulated processes is neural dedifferentiation (i.e., a decrease in neural selectivity, by which neural representations of processed information become less univocally distinguishable), possibly accompanied by the recruitment of additional cortical areas in the healthy aging brain. To date, these processes have been extensively studied on the neural level, yet their functional significance for cognitive behaviour remains largely unclear. This project will investigate neural dedifferentiation and its relationship to cognitive performance in the healthy aging brain. To this end, the investigators will use a combination of state-of-the-art technologies including simultaneous transcranial magnetic stimulation (TMS) and high-density electroencephalography (hd-EEG) as well as diffusion tensor imaging (DTI). Perspectives include a better understanding of the relationship between neurophysiological mechanisms and cognitive performance in the healthy aging brain.

Reactive Balance Training for Fall Prevention

The objective of this pilot study is to evaluate and compare the effect of three different perturbation based training devices on the reactive balance control among healthy young adults, healthy older adults, and neurologically impaired stroke individuals. Furthermore, the project aims to determine the feasibility and tolerability of 30-minutes of perturbation training using the SureFooted Trainer. Overall, the project directs to find out the long term effect of training on fall risk reduction and fall prevention. This study investigates the effects of perturbation training (slip and trip) based on the principles of motor learning. Perturbations in the form of slips and trips induced by the three different types of perturbation devices will displace the center of mass outside the base of support and challenge the stability, thereby inducing a fall and demand compensatory strategies in order to prevent it. Such perturbation training would train the motor system to improve stability control and vertical limb support. The project design aims to examine the ability of the central nervous system to mitigate the interference in stability control (if any) that is induced by opposing types of perturbations. The hypothesis of this study if supported by the results, will provide the difference in motor learning with training on three different perturbation devices. Furthermore, it would help to determine which of the three training devices is the most effective in developing defense mechanisms necessary to reduce fall-risk among community-living older adults and the neurological population.

MusiCare: Music Therapy & Innovative Technology

The number of older people living with cognitive impairment or dementia has increased the need for simple, inexpensive interventions to improve the quality of life for such individuals and their families. Policy-makers sensitive to issues associated with mental health challenges in aging have embraced social prescribing, and a wealth of research has flourished to study non-pharmacological forms of preventative intervention. Can music-therapy(MT) be one of them? Different studies demonstrated that music stimulates a range of cognitive and social functions. However, scientific studies assessing the value of MT for those who need support in later life are limited, and rigorous research is required to generate robust scientific evidence. The focus of this study is on developing novel forms of intervention for older adults who are healthy or experiencing mild-to-moderate cognitive decline, aiming at [i]understanding whether MT could be used in preventive programs to support cognitive functions, [ii]identifying the best match between types of MT and levels of cognitive decline. Moreover, recent developments of Robotic-Assistance-Technologies offer opportunities to explore how such technologies may be used to contribute to older adults wellbeing when integrated within care routines to facilitate MT delivery. Spanning across three-studies, the investigators will examine psychosocial benefits of 5-month MT interventions (one2one vs small-group MT) in healthy older adults and impaired older adults in care homes, compared to standard care. This latter group will receive MT afterwards. Further, researchers will investigate whether Robotic-Assistance-Technologies may enrich MT interventions and have additional benefits for the participants and translatability for community-based services. In order to measure these effects, psychological (cognitive functions, wellbeing, quality of life) and physiological (hormonal, cardiovascular & brain activity) measures will be compared before/after the intervention. The study will elucidate relationships between different types of MT and benefits to participants wellbeing, cognitive functions & social engagement, as well as the impact of robotic assistive technologies in public health services and social care.

A Randomised, Double-blind, Placebo-controlled, Parallel Study of the Effect of BrainPhyt on Cognitive Function in Healthy Older Subjects

In developed countries, the acceleration of the general population ageing has been widely described for decades, involving changes in public health policies. Among the health issues arising from this demographic change, the maintenance of cognitive function will be a major challenge in the next years, both in societal and economic terms. In this regard, some pharmacological and behavioural (e.g. physical activity, social involvement, intellectually demanding activities) preventive approaches have been evaluated to improve cognitive function with ageing. Among them, dietary interventions showed a potential interest to prevent cognitive decline during ageing. In this sense, there is a growing interest to find ecological solutions and to meet major societal challenge the use of microalgae as molecule of interest sources is a recent promising approach. Marine environments harbour a huge biological diversity of microalgae that represents a large source of almost untapped bioactive compounds. This biodiversity comprises 200,000 to 2 million species with about 35,000 which are described and 15,000 maintained in culture collections. Microalgae are able to produce bioactive molecules, such as pigments, fatty acids, peptides and sterols. Some of these compounds are unique and specifically found in the marine environment and they could be increasingly used as natural bioactive products for targeted applications. Fucoxanthin is one of the major carotenoid found in microalgae well known for its neuroprotective effect but to our knowledge no human studies were realized. Thus the objective is to evaluate, in healthy older adults, the effect of a 24-week period of daily supplementation of high and low BrainPhyt, doses on cognitive function parameters (Spatial Working Memory scores, Attention and vigilance, episodic memory, executive function), stress, mood, sleep quality and biomarkers.
