Filter by:The aim of this proposal is to identify immune biomarkers, genetic risk, and the clinical consequences of low count monoclonal B-cell lymphocytosis (LC MBL), a common premalignant condition affecting up to 17% of European adults age>40. LC MBL is a precursor to chronic lymphocytic leukemia (CLL), characterized by a circulating population of clonal B-cells. It is relatively understudied, despite emerging evidence of clinical consequences such as increased risk for life-threatening infections and lymphoid malignancies. Studies reported that male sex, age, family history of CLL, and CLL-susceptibility genetic loci were associated with LC MBL risk. These findings were reported in European ancestry individuals and have not been generalized to other thnicities. This study will provide this missing knowledge using a unique multi-ethnic Israeli population of Jews and Arabs that have one of the highest and lowest age-standardized incidence rates of CLL in the world, respectively, and characterized with different genetic backgrounds.
The number of older migrants with cognitive impairment and dementia living in Italy and attending national healthcare services is rapidly increasing. There is a need to develop diversity-sensitive policies and practices to include migrants and people with different cultural values in the public health response to dementia.
The APEX study is a multicenter, observational study designed to capture longitudinal follow-up of plasma biomarkers and cognitive and functional assessments on individuals who screen failed in the AHEAD study over approximately 4 years. Approximately 1000 participants will be enrolled across three groups: - Group A: Approximately 500 participants who are discordant on screening (plasma positive / Positron Emission Tomography (PET) negative), - Group B: Approximately 250 participants who are concordant on screening (plasma negative / PET negative), and - Group C: Approximately 250 participants selected from the individuals who previously screen failed prior to PET for the AHEAD study with oversampling of racial and ethnic populations underrepresented in Alzheimer's disease (AD) clinical trials. Primary Objectives: - Collect longitudinal cognitive and functional assessments and blood-based biomarker data - Evaluate, characterize, and compare the longitudinal cognitive and functional data between the three groups of participants - Compare longitudinal change across race and ethnicity, sex, and Apolipoprotein E (ApoE) status Exploratory Objectives: • Collect baseline amyloid PET on participants without prior amyloid PET data (Group C)
This study is a single center, randomized, double-blind, placebo-controlled Phase I clinical study in a single dose escalation to evaluate its safety, tolerability, pharmacokinetics, pharmacodynamics, and immunogenicity of CM383 in male healthy subjects.
Up to 25% of intensive care unit (ICU) survivors experience cognitive impairment comparable in severity to mild Alzheimer's disease and related dementias after hospital discharge. Older ICU survivors (ages 60 and older) are at highest risk for delirium and subsequent cognitive impairment, which contribute to higher risk for cognitive decline related to Alzheimer's disease and related dementias. Sleep and activity are essential for recovery from critical illness, yet ICU survivors experience both sleep deficiency and profound inactivity. About 75-80% of ICU patients experience circadian dysrhythmia, which contributes to cognitive decline and increases likelihood of developing Alzheimer's disease and related dementias. The scientific premises of the proposed study are: 1) a combined sleep promotion and cognitive training intervention will have synergistic effects to mitigate the risk of cognitive impairment and development of Alzheimer's disease and related dementias in older ICU survivors; and 2) chronotherapeutic timing of interventions (i.e., adjusting timing of interventions according to circadian rhythm) may improve intervention efficacy.
Some types of meditation lead heart rate to become more steady as breathing quiets whereas others lead to large heart rate swings up and down (oscillations) as breathing becomes deeper and slower. The current study is designed to investigate how daily practice of heart rate biofeedback during breathing in a pattern that either increases or decreases heart rate oscillation affect attention and memory and blood biomarkers associated with Alzheimer's disease.
This is a Phase 1, first in human (FIH), double-blind, placebo-controlled, single ascending dose (SAD) trial to assess the safety, tolerability, and pharmacokinetics (PK) of intravenously (IV) or subcutaneously (SC) injected ALIA-1758 in healthy male and female participants.
The purpose of this study is to test the Green Activity Program that was designed with Hispanic/Latino people living with memory challenges and their study partners to see if it can be done and if they enjoy the program. "Green activities" are nature activities that the person enjoys and can be done with other people or pets. For example, dog walking, hiking, outdoor yoga, and gardening are all green activities. The purpose of the program is to help people living with memory challenges participate in nature activities they enjoy. The goal of the program is to help people stay active and improve their health and well-being.
This clinical trial is recruiting people who either are at risk of AD - have build-up of beta-amyloid, but have no clinical symptoms, or with a diagnosis of mild cognitive impairment. People can take part if they have a certain level of plaques (beta-amyloid) in the brain, shown by a positron emission tomography (PET) scan, a medical imaging technique in which tracers are injected to visualize specific pathological processes in the brain. People who take part in this clinical trial (participants) will be given RO7269162 OR placebo for up to about 1 and a half years. The clinical trial team will see them every 3 weeks in the first 3 months and then every 6 weeks until the end of the trial. These hospital visits will include checks to see how the participant responds to the treatment and any side effects they may have. The total time of participation in the clinical trial will be 90 weeks.
This is a proof of concept observational study is to determine if there is correlation between Aβ plaques and vascular findings in the Retina versus brain ARIA.
