How is COGNItive Function Affected by Cardiac Resynchronisation Therapy?

The primary objective of COGNI-CRT is to assess whether Cardiac Resynchronisation Therapy (CRT) can improve cognitive function in patients with systolic HF (LVEF ?35%), when compared to a control group of patients implanted with an Implantable Cardioverter-Defibrillator (ICD) or a permanent pacemaker (PPM) with systolic HF (LVEF ?35%). This clinical investigation is a prospective, single-centre cohort study. Each participant will be followed for 6 months. The study will collect data over 3 years; 2.5 years for enrolment and 6 months until the last participant completes the last 6-month follow-up visit. N.B: COGNI-CRT does NOT affect the patient's care pathway - the patients who will be selected for participation are those who have already been referred for the device implant. The ONLY difference to the patient's care pathway caused by COGNI-CRT is the addition of a battery of cognitive function tests, which involves asking the patient questions and asking them to complete questionnaire-like cognitive tests. NTpro-BNP levels, NYHA classification and LVEF will be measured prior to device implantation and at 6-months post-implant to assess the device's impact on the participant's heart failure (and CRT response). N.B: NT-proBNP, NYHA classification and LVEF are all parts of the patient's standard care pathway, COGNI-CRT is just utilising the data collected as part of the investigation. The main study arm and control group allows COGNI-CRT to assess 3 potential outcomes for patients with severe HF (LVEF <35%): Cognitive function is not improved by CRT, ICDs or PPMs Cognitive function can be improved by the assurance of rate control offered by CRT, ICDs and PPMs Cognitive function can be improved by the assurance of ventricular synchronisation and rate control provided by the additional left ventricular lead in CRT devices.

ICU Doulas Providing Psychological Support

Many patients who survive critical illness suffer from symptoms of anxiety, depression, or post-traumatic stress disorder (PTSD) after leaving the intensive care unit (ICU). Memories of frightening and delusional experiences in the ICU appear to be the strongest potentially modifiable risk factor. Research on the formation of fear and associated memories shows that if mitigating information about a traumatic event is introduced during the time between memory formation and its recall, the emotional experience of the memory can be modified in a positive manner. This means that in order to prevent mental health problems in critical illness survivors, psychological support needs to take place in parallel with medical treatment in the ICU. The Researchers hypothesize that early psychological support for the critically ill can decrease mental health morbidity in critical illness survivors. However, providing consistent psychological support intervention is a challenge for busy ICU clinicians. It is not feasible to hire behavioral medicine trained psychologists to become permanent ICU staff nationwide. Doulas, trained lay health care providers who provide emotional support to women in labor, have been identified as reliable yet affordable alternative. Given common elements of their services and our intervention, doulas are in an ideal position to administer early psychological support. The objective of this project is to refine and test a behavioral intervention to be administered in parallel with medical treatment in the ICU. This will be accomplished by training doulas in providing standardized psychological support intervention and refining the intervention based on stakeholder feedback

Cognitive Stimulation for Elderly Bipolar Patients

Age is a major risk factor for the development of cognitive disorders and neurodegenerative pathologies. Cognitive disorders during the phases of bipolar disease are known to exist, and alterations increase significantly after the age of 65. Drug treatments seem to have only a limited effect. A cognitive stimulation program has proven his benefit to patients over 65 with neurodegenerative diseases (Israel, 2004). We propose to evaluate this cognitive stimulation program that we have adapted to bipolar disease.

From Brain Currents to Interpersonal Flow: Investigating the Social Processing Stream of Schizophrenia

The overall objective of this project is to identify the neural signature of the impaired ability to relate socially seen in individuals with schizophrenia. A hypothesized path from the neural processes of social cognition, to social cognition assessed behaviorally, to real-life social interactions is examined. Secondary aims are to compare electrophysiological measures of high vs low level social cognition; to develop assessment methods of real-life behavior; and to increase the ecological validity of schizophrenia research. Much research within the field is devoid of personal meaning and interpersonal context. This project's use of personalized assessment allows for an ecologically valid approach to the social deficits of schizophrenia.

Cognitive Impairment in Ageing People

Mild cognitive impairment (MCI) and neurocognitive disorder such as Alzheimer's disease (AD) and Vascular dementia (VaD) have become common diseases in the elderly. The burden of dementia is rising in China, with major medical, social and economic impacts. To address this important public health problem, cohort study on elderly cognitive disorders should be carry out. The methods of early prevention, early diagnosis and early treatment the cognitive disorders in elderly should be found to reduce the burden of the social and economic issue due to dementia. At present, the international corresponding guidelines have taken gene and brain imaging biomarkers as important indicators of dementia pathogenesis research, accurate diagnosis and targeted intervention. The study will construct a prospective cohort to establish database that provide not only comprehensive epidemiological data on the MCI and neurocognitive disorder in ageing people, but also complete the construction of biological samples bank and clinical diagnosis and treatment information database. Using the database, the study will identify the conversion rates from MCI to dementia and risk factors for the progression from MCI to dementia or AD. The study will also apply and develop brain structural and pathological imaging technology to support precision diagnosis of senile cognitive disorders. The study have goals to identify and validate imaging and blood/CSF biomarkers for the early detection and tracking of cognitive disorders.

Optimal Blood Pressure for the prevenTIon of Major vAscuLar Events in Patients With DIABETES Mellitus (OPTIMAL-DIABETES)

High blood pressure (BP) is a major public health concern, especially in low and middle income countries. High BP is a highly prevalent condition, and it is usually associated with diabetes mellitus. Both high BP and diabetes are risk factors for major cardiovascular events including cardiovascular death, acute myocardial infarction, stroke, unstable angina and heart failure. In addition, high BP is also related to cognitive decline. The OPTIMAL-DIABETES trial consists of a two-arm, multicenter, randomized clinical trial designed to test whether a lower systolic blood pressure (SBP) target will reduce the occurrence of major cardiovascular events in diabetic patients compared to the standard SBP target.

Dexmedetomidine to Reduce the Incidence of POCD After Open Cardiac Surgery

Anesthesia is a drug induced, reversible, comatose state that facilitates surgery and it is widely assumed that cognition returns to baseline after anesthetics have been eliminated. However, many patients have persistent memory impairment for weeks to months after surgery. Cardiac surgery appears to carry the highest risk of postoperative cognitive dysfunction (POCD). These cognitive deficits are associated with increased mortality, prolonged hospital stay and loss of independence. The investigators propose to investigate the role of Dexmedetomidine (DEX) in preventing long-term POCD after cardiac surgery and enhancing early postoperative recovery. It is anticipated that DEX will be the first effective preventative therapy for POCD, improve patient outcomes, and reduce length of stay and healthcare costs.

Evaluation of an Educational Program in the Prevention of the Driving Risks in Patients With Neurocognitive Disorders : ACCOMPAGNE

ACCOMPAGNE study proposes to evaluate an educational program for the patient / caregiver dyad, intended to accompany the patient towards the implementation of self-regulation strategies in the driving activity. The program, based on group workshops with the presence of the patient and the caregiver, is led by an interdisciplinary team. It follows all the intervention recommendations described in the literature: to make the patient a decision-maker, to allow advanced planning of discussions between the family member and the caregiver, to give information on the consequences of TNCs and sensory disorders. This program provides psychological support in the management of the problems and the mourning of a future cessation of the driving activity, an awareness of the risky and avoidable situations, information on alternative solutions and available resources in the event of reduced driving. The program is created to support the implementation of self-regulation strategies for safe driving and a gradual reduction of driving activity. This study may be included in Measure 5 of the Neuro-Degenerative Diseases Plan (PMND) 2014-2019. This plan recommends to strengthen the self-management of patients and their relatives in the disease.

Carotid Revascularization and Medical Management for Asymptomatic Carotid Stenosis Trial - Hemodynamics (CREST-H)

We aim to determine whether cognitive impairment attributable to cerebral hemodynamic impairment in patients with high-grade asymptomatic carotid artery stenosis is reversible with restoration of flow. To accomplish this aim CREST-H will add on to the NINDS-sponsored CREST-2 trial (parallel, outcome-blinded Phase 3 clinical trials for patients with asymptomatic high-grade carotid artery stenosis which will compare carotid endarterectomy plus intensive medical management (IMM) versus IMM alone (n=1,240), and carotid artery stenting plus IMM versus IMM alone (n=1,240) to prevent stroke and death). CREST-H addresses the intriguing question of whether cognitive impairment can be reversed when it arises from abnormal cerebral hemodynamic perfusion in a hemodynamically impaired subset of the CREST-2 -randomized patients. We will enroll 500 patients from CREST-2, all of whom receive cognitive assessments at baseline and yearly thereafter. We anticipate identifying 100 patients with hemodynamic impairment as measured by an inter-hemispheral MRI perfusion "time to peak" (TTP) delay on the side of stenosis. Among those who are found to be hemodynamically impaired and have baseline cognitive impairment, the cognitive batteries at baseline and at 1 year will determine if those with flow failure who are randomized to a revascularization arm in CREST-2 will have better cognitive outcomes than those in the medical-only arm compared with this treatment difference for those who have no flow failure. We hypothesize that hemodynamically significant "asymptomatic" carotid disease may represent one of the few examples of treatable causes of cognitive impairment. If cognitive decline can be reversed in these patients, then we will have established a new indication for carotid revascularization independent of the risk of recurrent stroke.

Functionally-tailored Oral Care Intervention for Community-dwelling Older Adults With Dementia and Their Caregivers

The specific aims of this study are: Aim 1. Develop a staged and modifiable dyadic oral care intervention to provide functionally-tailored oral care rehabilitation for community-dwelling persons with dementia (PWD) and need-based skills training their family caregivers (CGs). Based on the literature review and MCWB, a 4-week intervention with 8 modules, including universal modules (e.g., environmental changes), CG modules (e.g., cuing strategies) and modules for both PWD and CGs (e.g., oral care techniques), will be developed addressing the relevant SCT constructs (e.g., functional deficits of PWD and caregiving needs of CGs). Guided by a validated, widely-used theory of rehabilitation medicine, modules will be used alone or in combination to provide personalized, hand-on, functionally-tailored oral care rehabilitation for PWD along with skills training for CGs to match their caregiving needs. The training focus shifts from the PWD to the CG, as the independence of the PWD decreases. Semi-structured interviews with family CGs will then be conducted (until data saturation is reached) to understand their oral care needs, desired intervention approaches, and the perceived feasibility and utility of the intervention. The intervention will be revised and then pilot tested with 4 dyads, one per each of the four functional levels of the DAT. Aim 2. Evaluate the feasibility and efficacy of the intervention in home settings through a randomized, controlled trial with 40 pairs of PWD and their primary CGs, including immediate post-intervention and 3-month follow-up. Dyads will be stratified into 4 functional levels based on the PWD's DAT score and then randomly assigned to the intervention or control (non-tailored usual care) group.

Pre-FRONTal Brain STability, Key for Action Against Disability in AGing

Cognitive and mobility impairments are critical contributors to dementia and disability in older adults, and can be caused by neurodegenerative and neurovascular changes at the pre-frontal (PF) brain areas. In a previous technological project funded by ISCiii, the investigators adapted a non-invasive, point-of-care optical methods (fNRIS/fDCS technology) to study PF metabolism and blood flow activation during cognitive and motor tasks, in older adults with and without cognitive impairment. These methods are sensitive to change after physical exercise (PE) and after selectively and safely stimulating PF areas with electrical transcranial direct current stimulation (tCS). PE and tCS have shown benefits for cognition and mobility in the elderly, but their prolonged effect on PF hemodynamic activation has not been studied. Understanding the specific action of these interventions on the brain, and their clinical cognitive and motor impact, is key to fine-tune appropriate treatment strategies. The FRONT STAGE project aims to compare, through a 3 arms single-blind randomized clinical trial, the impact of a 10 weeks, 1 hour/week program of PE (arm 1) Vs PE+tCS (arm 2) and Vs a control group (arm 3, healthy aging sessions and control of cardiovascular risk factors). The PE program is already implemented in primary care, as part of another previous project of the investigators' research group. Outcomes will include the optical measurement of PF metabolism and blood flow and clinical measures of cognitive and physical function. Front STAGE project will recruit 93 older adults with cognitive impairment and slow gait, but without dementia or disability in the activities of daily living (N=31 per arm). They will receive a comprehensive geriatric assessment at baseline, together with the optical, cognitive and physical measures, and will be follow-up at 3 and 6 months. Weekly physical activity through accelerometry will be controlled in analyses. FRONT STAGE project centered on aging and the prevention of dementia and disability, will provide, translationally, more evidence to support and enlarge the clinical application of these interventions, and will contribute to foster further research in this field.
