Neighborhood Characteristics And Dementia Symptomology Among Community-Dwelling Older Adults With Alzheimer’S Disease, Dana M. Alhasan, Matthew C. Lohman Ph.D., Jana A. Hirsch, Margaret Chandlee Miller Ms, Ph.D., Bo Cai Ph.D., Chandra L. Jackson

Faculty Publications

Background: Neuropsychiatric symptoms (NPSs) lead to myriad poor health outcomes among individuals with Alzheimer’s disease (AD). Prior studies have observed associations between the various aspects of the home environment and NPSs, but macro-level environmental stressors (e.g., neighborhood income) may also disrupt the neuronal microenvironment and exacerbate NPSs. Yet, to our knowledge, no studies have investigated the relationship between the neighborhood environment and NPSs.

Methods: Using 2010 data among older adults with AD collected from a sample of the South Carolina Alzheimer’s Disease Registry, we estimated cross-sectional associations between neighborhood characteristics and NPSs in the overall population and by race/ethnicity. Neighborhood …

Busbee, Nicholas Dopkins, Osama A. Abdulla, Yin Zhong, Jiajia Zhang Ph.D., Mitzi Nagarkatti, Prakash S. Nagarkatti

Faculty Publications

While blockade of cannabinoid receptor 1 (CB1) has been shown to attenuate diet-induced obesity (DIO), its relative role in different cell types has not been tested. The current study investigated the role of CB1 in immune vs non-immune cells during DIO by generating radiation-induced bone marrow chimeric mice that expressed functional CB1 in all cells except the immune cells or expressed CB1 only in immune cells. CB1^-/- recipient hosts were resistant to DIO, indicating that CB1 in non-immune cells is necessary for induction of DIO. Interestingly, chimeras with CB1^-/- in immune cells showed exacerbation in DIO combined with …

Addressing Immunizations In Nursing Education: Immunization Resources For Undergraduate Nursing, Sheryl Buckner, Ruth Gallego, Diana Mcnaughton, Susan Brasher, Joan Stanley, Allison Jacobs, Jennifer Hamborsky, Sarah Schillie, Stacie Hunsaker, Kathy J. Kyler, Allison L. Lewis, Donna Page

Faculty Publications

Nursing faculty are challenged to integrate immunization content in prelicensure nursing curricula. Historically, most immunization content has been delivered in pediatrics courses, with less emphasis on other populations across the lifespan. Skills related to vaccine administration may be prioritized over the most current immunization science, such as pathophysiology, immunology, and epidemiology. As the most trusted profession rated by the public (Saad, 2020), nurses are ideally suited to address vaccine hesitancy and promote vaccination in the communities they serve. Nurses apply active listening, problem solving, and communication skills with patients and their families, contributing to a person's confidence in their decision …

Ethnic/Racial Differences In Alcohol Use: Does Drinking Refusal Self-Efficacy Matter?, P. Priscilla Lui, Savannah M. Krantz, Michael B. Madson

Faculty Publications

Introduction: College students—including those of Hispanic backgrounds—are at risk for hazardous drinking. Research has shown robust group differences between Hispanic and White individuals in alcohol use outcomes. The ability to resist alcohol consumption can be leveraged to reduce hazardous drinking; however, little research has examined Hispanic-White differences and whether drinking refusal self-efficacy accounts for group differences in hazardous drinking. Considering Hispanic individuals make up the largest ethnic/racial minority group in the United States, it is important to identify malleable psychological factors that prevent and reduce drinking problems. Method: Hispanic and White college students at two predominantly White institutions …

Faculty Publications

Breast cancers (BrCas) that overexpress oncogenic tyrosine kinase receptor HER2 are treated with HER2-targeting antibodies (such as trastuzumab) or small-molecule kinase inhibitors (such as lapatinib). However, most patients with metastatic HER2⁺BrCa have intrinsic resistance and nearly all eventually become resistant to HER2-targeting therapy. Resistance to HER2-targeting drugs frequently involves transcriptional reprogramming associated with constitutive activation of different signaling pathways. We have investigated the role of CDK8/19 Mediator kinase, a regulator of transcriptional reprogramming, in the response of HER2⁺BrCa to HER2-targeting drugs. CDK8 was in the top 1% of all genes ranked by correlation with shorter relapse-free …
