Extravasated Brain-Reactive Autoantibodies Perturb Neuronal Surface Protein Expression In Alzheimer's Pathology, Wardah Bajwa, Mary Kosciuk, Randel L. Swanson, Anuradha Krishnan, Venkat Venkataraman, Robert Nagele, Nimish Acharya

Rowan-Virtua Research Day

Background: Increased blood-brain barrier (BBB) permeability is reported in both the neuropathological and in vivo studies in both Alzheimer’s Disease (AD) and age matched cognitively normal, no cognitive impairment (NCI), subjects. Impaired BBB allows various vascular components such as immunoglobulin G (IgG) to extravasate into the brain and specifically bind to various neuronal surface proteins (NSP), also known as brain reactive autoantibodies (BrABs). This interaction is predicted to further enhance deposition of amyloid plaques.

Hypothesis: Interaction between extravasated BrABs and its cognate NSPs lower the expression of that NSPs in AD patients.

Methods: We selected Western blotting technique to study …

BACKGROUND: Cerebral glucose hypometabolism is consistently observed in individuals with Alzheimer's disease (AD), as well as in young cognitively normal carriers of the Ε4 allele of Apolipoprotein E (APOE), the strongest genetic predictor of late-onset AD. While this clinical feature has been described for over two decades, the mechanism underlying these changes in cerebral glucose metabolism remains a critical knowledge gap in the field.

METHODS: Here, we undertook a multi-omic approach by combining single-cell RNA sequencing (scRNAseq) and stable isotope resolved metabolomics (SIRM) to define a metabolic rewiring across astrocytes, brain tissue, mice, and human subjects expressing APOE4.

RESULTS: Single-cell …

Jennifer Tjia

Introduction: The increasing prevalence of antipsychotic medication use in residents of nursing homes (NH) in the absence of psychiatric diagnoses is concerning. To address these concerns, it is essential to explore how these medications are being prescribed and managed in the NH setting. Our objectives were to understand the decision-making process that influences prescribing and factors that trigger administration of antipsychotic medications to residents with dementia in NHs and to explore why residents remain on antipsychotic medications over an extended period of time.

Methods: Interviews with prescribers, caregivers, and family members, on-site observations in study facilities, and review of NH …

Department of Family & Community Medicine Faculty Papers

A 62yo white male presented to same day clinic with an erythematous nodular rash. He was initially treated with antibiotics for a furunculosis, but the rash worsened and he was eventually found to have secondary syphilis. He is an MSM who had a prior history of syphilis, putting him at high risk for STI’s and HIV, and should have been undergoing annual screening. He was found to be HIV positive. The rates of STI’s and HIV are increasing in older Americans. Despite this, physicians do not regularly screen this population for unsafe sexual behavior. This case emphasizes the importance of …

Intracerebral Hemorrhage For The Palliative Care Provider: What You Need To Know., B Brent Simmons, Susan M Parks

Department of Family & Community Medicine Faculty Papers

Intracerebral hemorrhage (ICH) makes up 10%-30% of all strokes. Palliative care providers are often asked to get involved with ICH cases to aid with development of short-term and long-term goals. Prognosis can be calculated using the ICH score (based on Glasgow Coma Score score, ICH volume, presence of intraventricular hemorrhage, age, and location of origin) or the Essen score (based on age, NIH Stroke Scale [NIHSS], and level of consciousness). Do-not-resuscitate (DNR) status is important to discuss with families. Expert consensus states DNR is appropriate if the patient has two of the following: severe stroke, life-threatening brain damage, or significant …
