Project HOPEFUL: A PN-RCT With Implementation Science

This PN-RCT replicates and evaluates an 8-week warm calling treatment (i.e. caring contacts) delivered to older adults receiving home and community-based services (HCBS; classified as "homebound") in 20-30 minute call "dosages", across 3 conditions, while adding in implementation science measures at multiple levels. Conditions include 2 treatment (i.e. treatment provided by helpers trained in a standardized and manualized Belongingness and Empathy training grounded in narrative reminiscence and the befriending literature (BE condition), and treatment provided by helpers trained in BE + a standardized, manualized, and evidence based suicide intervention training, the Aging Variant of LivingWorks ASIST (BE + ASIST condition), and 1 control (no treatment during the trial; opportunity to receive treatment after the 8 weeks). At the conclusion of treatment, acceptability, appropriateness, feasibility, useability, and sustainability of the program will be evaluated by interventionists, senior center leadership, and regional leadership.

A Study of Psychedelics in Healthy Older Adults With Low Well-being

This study is being conducted to understand changes in brain activity following administration of two different drugs (Psilocybin and Dextromethorphan) in older adults with low well-being. The main questions it aims to answer are, does psilocybin: 1. Acutely increase complexity of EEG activity in older adults with low well-being, as modulated by the presence of biomarkers of Alzheimer's disease (AD) pathology. 2. Longitudinally decrease plasma markers of neuroinflammation, as modulated by the presence of biomarkers of AD pathology. 3. Explore longitudinal changes in autonomic physiology via wearable recording devices as well as longitudinal structural and functional brain changes measured in the MRI Participants will be in the study for up to 3 months, which will include 3 to 4 in person visits and 3 to 4 remote visits. Most visits will be between 1 to 3 hours, but the dosing visit will last a minimum of 8 hours and could be as long as 12 hours. During the dosing visit, all participants will receive a single dose of the study drugs and dosages listed below. Researchers will compare participants who receive the following drug options: * A low-to-moderate dose of Psilocybin (5-10 mg) * A moderate-to-high dose of Psilocybin (25-30 mg) * A low-to-moderate dose of Dextromethorphan (30-60 mg) * A moderate-to-high dose of Dextromethorphan (80-90 mg)

Integrating Depression Care Into HIV Services for Older People With HIV Using a Stepped Care, Task-Sharing Approach.

Depression levels will be compared using PHQ-9 in the Treatment as Usual arm(TAU) VS intervention arm to see if the stepped care intervention is effective in treating depression. The main questions it aims to answer are: * Needs assessment of stepped-care integration versus usual care for treating depression in older adults living with HIV? * How effective will the stepped care task-sharing (SCT) model in reducing depressive symptoms and improving HIV treatment outcomes in older PLHIV in Nigeria? Participants who screen positive for depression PHQ-9 ≥10 will be randomized into 2 arms for treatment using a systemized ballot system: TAU arm and Intervention arm. TAU arm will receive current treatment available for depression at the HIV center. Intervention arm will receive the stepped-care intervention in stages based on their symptom severity. Follow-up assessments at (6 weeks, 3months and 6 months) will be conducted by assessors who would be blinded to the different groups (TAU arm VS intervention arm).

Let's Increase Fuerza (Strength) Through Exercise and Diet

The purpose of the study is to conduct a 6-month randomized controlled trial among Latinos ages 50+ at risk for cognitive decline and compare the efficacy of a remote-delivered, culturally tailored Latin dance program and strength training coupled with a Mediterranean-Dash Intervention for Neurodegenerative Delay (MIND) diet (IG) compared to a Latin dance and MIND diet program (CG) on cognitive performance, CVD risk factors, MIND diet adherence, physical activity, biomarkers, and psychosocial outcomes. Participants will: * Randomly be placed in the intervention (IG) or control group (CG) * Have 2 pre and post intervention testing visits * Have weekly sessions during the 6-month trial
