Comparing the Outcomes of Osteocutaneous Radial Forearm and Fibula Free Flaps in the Reconstruction of Mandibular Osteoradionecrosis.

Background: This study compares the outcomes of osteocutaneous radial forearm free flap (OC-RFFF) and fibula free flap (FFF) reconstruction of mandibular osteoradionecrosis (ORN).

Methods: Retrospective review of patients undergoing OC-RFFF/FFF reconstruction for mandible ORN between 2005 and 2020 at a tertiary center. Patient characteristics, postoperative complications, and functional outcomes were evaluated using chi-squared and logistic regression analysis.

Neuropsychiatric symptom burden in early-onset and late-onset Alzheimer's disease as a function of age.

Introduction: We examined the burden of neuropsychiatric symptoms (NPSs) in early-onset (EO) and late-onset (LO) Alzheimer's disease (AD) and adjusted for age effects via the inclusion of cognitively unimpaired (CU) individuals.

Methods: Cross-sectional data from 2940 EOAD, 8665 LOAD, and 8775 age-stratified CU individuals (early-CU, n = 2433; late-CU, n = 6342) from the National Alzheimer's Coordinating Center database were included. Fisher's exact tests compared EOAD and LOAD on the presence and severity of NPSs.

Baseline neuropsychiatric symptoms and psychotropic medication use midway through data collection of the Longitudinal Early-Onset Alzheimer's Disease Study (LEADS) cohort.

Introduction: We examined neuropsychiatric symptoms (NPS) and psychotropic medication use in a large sample of individuals with early-onset Alzheimer's disease (EOAD; onset 40-64 years) at the midway point of data collection for the Longitudinal Early-onset Alzheimer's Disease Study (LEADS).

Methods: Baseline NPS (Neuropsychiatric Inventory - Questionnaire; Geriatric Depression Scale) and psychotropic medication use from 282 participants enrolled in LEADS were compared across diagnostic groups - amyloid-positive EOAD (n = 212) and amyloid negative early-onset non-Alzheimer's disease (EOnonAD; n = 70).

Results: Affective behaviors were the most common NPS in EOAD at similar frequencies to EOnonAD.

Accelerating diversity in Alzheimer's disease research by partnering with a community advisory board.

Introduction: Community advisory boards (CABs) and researcher partnerships present a promising opportunity to accelerate enrollment of underrepresented groups (URGs). We outline the framework for how the CAB and researchers at the Indiana Alzheimer's Disease Research Center (IADRC) partnered to accelerate URG participation in AD neuroimaging research.

Methods: CAB and the IADRC researchers partnered to increase the CAB's impact on URG study enrollment through community and research interactions.
