Advancements in Immunity and Dementia Research: Highlights from the 2023 AAIC Advancements: Immunity Conference.

The immune system is a key player in the onset and progression of neurodegenerative disorders. While brain resident immune cell-mediated neuroinflammation and peripheral immune cell (eg, T cell) infiltration into the brain have been shown to significantly contribute to Alzheimer's disease (AD) pathology, the nature and extent of immune responses in the brain in the context of AD and related dementias (ADRD) remain unclear. Furthermore, the roles of the peripheral immune system in driving ADRD pathology remain incompletely elucidated.

Western Diet and Inflammatory Mechanisms in African American Adults With Heart Failure.

Background: Black adults have a higher risk for heart failure (HF) than others, which may be related to higher cardiovascular risk factors and also inflammatory dietary patterns. The Western diet is associated with inflammation and contributes to HF. Trimethylamine N-oxide is a diet-linked metabolite that contributes to inflammation and is associated with higher tumor necrosis factor-alpha (TNF-α) levels, especially in HF populations.

Pilot: Salivary Lactoferrin as a Biomarker of Alzheimer's Disease.

Background: Alzheimer's disease (AD) research has focused on developing accessible biomarkers that accurately detect disease pathology and progression before symptoms present. Lactoferrin (Lf) is an iron-binding antimicrobial glycoprotein found in all biological fluids, and its concentration in saliva has been correlated with AD symptoms. This pilot project aimed to determine whether salivary lactoferrin (sLF) has potential as a biomarker for AD.

Comorbid Diabetes Is Associated With Dyspnea Severity and Cardiometabolic Biomarkers in Black Adults With Heart Failure.

Background: Comorbidities such as Type 2 diabetes mellitus significantly and adversely influence heart failure outcomes, especially in Black adult populations. Likewise, heart failure has a negative effect on diabetes and cardiometabolic outcomes. Dyspnea, a common symptom of heart failure, often correlates with disease severity and prognosis.

Improving Screening for Social Determinants of Health in an Outpatient Complex Care Clinic.

Background: Families of children with medical complexity (CMC) may face challenges related to Social Determinants of Health (SDoH). Although standardized SDoH screening has been implemented in numerous medical settings, there has been limited study of screening among CMC. Our global aim is to improve access to institutional and community resources for families of CMC with identified needs.
