Two of every three persons living with dementia reside in low- and middle-income countries (LMICs). The projected increase in global dementia rates is expected to affect LMICs disproportionately. However, the majority of global dementia care costs occur in high-income countries (HICs), with dementia research predominantly focusing on HICs. This imbalance necessitates LMIC-focused research to ensure that characterization of dementia accurately reflects the involvement and specificities of diverse populations. Development of effective preventive, diagnostic, and therapeutic approaches for dementia in LMICs requires targeted, personalized, and harmonized efforts. Our article represents timely discussions at the 2022 Symposium on Dementia and Brain Aging …

School of Medicine Publications and Presentations

Currently, more than 55 million people around the world suffer from dementia, and Alzheimer’s Disease and Related Dementias (ADRD) accounts for nearly 60–70% of all those cases. The spread of Alzheimer’s Disease (AD) pathology and progressive neurodegeneration in the hippocampus and cerebral cortex is strongly correlated with cognitive decline in AD patients; however, the molecular underpinning of ADRD’s causality is still unclear. Studies of postmortem AD brains and animal models of AD suggest that elevated endoplasmic reticulum (ER) stress may have a role in ADRD pathology through altered neurocellular homeostasis in brain regions associated with learning and memory. To study …

Clinical Efforts Double Disparity For Nonphysician Urim Faculty: Implications For Academic Family Medicine, Stacy A. Ogbeide, Deepu George, Adrian Sandoval, Yajaira Johnson-Esparza, Maria Montanez Villacampa

School of Medicine Publications and Presentations

With a new definition of high-quality primary care and the shift in nonphysician faculty’s role as core faculty members in family medicine residency programs, new attention is needed on the delineation of clinical efforts and clinical efforts disparities across disciplines (eg, psychology, marriage and family therapy, pharmacy) within departments of family medicine. Additionally, those who identify as underrepresented in medicine (URiM), specifically those who are nonphysician faculty, are dually impacted by the clinical efforts double disparity. This paper examines the current landscape of clinical efforts in academic family medicine for physician faculty and nonphysician faculty as well as discusses how …

Statistical Genetic Approaches To Investigate Genotype-By-Environment Interaction: Review And Novel Extension Of Models, Vincent P. Diego, Eron G. Manusov, Marcio Almeida, Sandra Laston, David Ortiz, John Blangero, Sarah Williams-Blangero

School of Medicine Publications and Presentations

Statistical genetic models of genotype-by-environment (G×E) interaction can be divided into two general classes, one on G×E interaction in response to dichotomous environments (e.g., sex, disease-affection status, or presence/absence of an exposure) and the other in response to continuous environments (e.g., physical activity, nutritional measurements, or continuous socioeconomic measures). Here we develop a novel model to jointly account for dichotomous and continuous environments. We develop the model in terms of a joint genotype-by-sex (for the dichotomous environment) and genotype-by-social determinants of health (SDoH; for the continuous environment). Using this model, we show how a depression variable, as measured by the …

Ribosomal S6 Kinase 2-Forkhead Box Protein O4 Signaling Pathway Plays An Essential Role In Melanogenesis, Dohyun Jeung, Ga-Eun Lee, Weidong Chen, Jiin Byun, Soo-Bin Nam, You-Min Park, Hye Suk Lee, Han Chang Kang, Joo Young Lee, Dae Joon Kim

School of Medicine Publications and Presentations

Although previous studies have examined the signaling pathway involved in melanogenesis through which ultraviolet (UV) or α-melanocyte-stimulating hormones (α-MSH) stimuli act as key inducers to produce melanin at the stratum basal layer of the epidermis, the signaling pathway regulating melanogenesis is still controversial. This study reports that α-MSH, not UVA and UVB, acted as a major stimulus of melanogenesis in B16F10 melanoma cells. Signaling pathway analysis using gene knockdown technology and chemical inhibitors, the mitogen-activated protein kinase kinase (MEK)/extracellular signal-regulated kinase (ERK)/p90 ribosomal S6 kinase 2 (RSK2) played an important role in melanogenesis. Unexpectedly, LY294002, a PI3K inhibitor, increased melanogenesis …

A Comparative Analysis Of Positive And Negative Stimuli For Takotsubo Cardiomyopathy: A Pooled Analysis Of Two Studies And A Systematic Review, Arankesh Mahadevan, Vamsikalayan Borra, Lakshmi Prasanna Vaishnavi Kattamuri, Vikash Jaiswal, Ikechukwu R. Ogbu

School of Medicine Publications and Presentations

Takotsubo cardiomyopathy (TTC) is characterized by transient myocardial dysfunction triggered by both negative and positive emotional experiences, known respectively as broken heart syndrome (BHS) and happy heart syndrome (HHS). Despite the scarcity of comparative analyses between HHS and BHS in the literature, our pooled analysis, incorporating two retrospective registry analyses of 1395 TTC patients (57 HHS and 1338 BHS), reveals that while BHS is more prevalent, both conditions exhibit similar clinical presentations and outcomes. Statistical analyses, utilizing binary random effects models, indicate that diabetes mellitus is less common in HHS patients and serves as a predictor for BHS. Furthermore, there …

Promoting Diverse Perspectives: Addressing Health Disparities Related To Alzheimer's And All Dementias, Gladys Maestre, Carl Hill, Percy Griffin, Stephen Hall, William Hu, Jason Flatt, Ganesh Babulal

School of Medicine Publications and Presentations

Dementia research lacks appropriate representation of diverse groups who often face substantial adversity and greater risk of dementia. Current research participants are primarily well-resourced, non-Hispanic White, cisgender adults who live close to academic medical centers where much of the research is based. Consequently, the field faces a knowledge gap about Alzheimer's-related risk factors in those other groups. The Alzheimer's Association hosted a virtual conference on June 14–16, 2021, supported in part by the National Institute on Aging (R13 AG072859-01), focused on health disparities. The conference was held entirely online and consisted of 2 days of core programming and a day …

School of Medicine Publications and Presentations

Nesidioblastosis is a term used to describe histologic changes in the pancreatic cell, which are defined by beta cell hypertrophy and the formation of ductoinsular complexes. It is a disease previously most extensively identified in neonates and is a rare cause of endogenous hypoglycemia in the adult population. However, with increasing numbers of gastric bypass surgeries for the management of obesity in recent years, there has been a growing number of populations with post-gastric bypass surgery-related nesidioblastosis. Here, we will present a case of a 60-year-old female with a history of Roux-en-Y gastric bypass (RYGB) surgery who initially presented with …

The Effects Of Genetic And Modifiable Risk Factors On Brain Regions Vulnerable To Ageing And Disease, Jordi Manuello, Joosung Min, Paul Mccarthy, Fidel Alfaro-Almagro, Soojin Lee, Stephen Smith, Lloyd T. Elliott, Anderson M. Winkler, Gwenaëlle Douaud

We have previously identified a network of higher-order brain regions particularly vulnerable to the ageing process, schizophrenia and Alzheimer’s disease. However, it remains unknown what the genetic influences on this fragile brain network are, and whether it can be altered by the most common modifiable risk factors for dementia. Here, in ~40,000 UK Biobank participants, we first show significant genome-wide associations between this brain network and seven genetic clusters implicated in cardiovascular deaths, schizophrenia, Alzheimer’s and Parkinson’s disease, and with the two antigens of the XG blood group located in the pseudoautosomal region of the sex chromosomes. We further reveal …

Clinical Characteristics Of Idiopathic Granulomatous Mastitis In A Hispanic Border Population: A Case Series And Literature Review, Percy M. Thomas, Laura R. Uribe, Aminadab G. Flores, Emilia C. Dulgheru

School of Medicine Publications and Presentations

Idiopathic granulomatous mastitis (IGM) is an autoimmune condition of the breast that is commonly encountered in women of non-white ethnicity such as Southeast Asians, Middle Easterners, and Hispanics. This condition often presents as a painful breast mass, and many patients undergo invasive diagnostic procedures or surgical excision, which can lead to disfiguring scars. Early recognition and prompt treatment with immunosuppressive medications can prevent invasive workups and management. Although previously thought to require an exclusively surgical approach, it now prompts interdisciplinary management. In this context, we present a case series of patients with IGM in a Hispanic population of South Texas.

Metabolic Syndrome Traits Exhibit Genotype-By-Environment Interaction In Relation To Socioeconomic Status In The Mexican American Family Heart Study, Vincent P. Diego, Eron G. Manusov, Xi Mao, Marcio A. Almeida, Juan M. Peralta, Joanne E. Curran, Michael C. Mahaney, Harald H. H. Goring, John Blangero, Sarah Williams-Blangero

School of Medicine Publications and Presentations

Background: Socioeconomic Status (SES) is a potent environmental determinant of health. To our knowledge, no assessment of genotype-environment interaction has been conducted to consider the joint effects of socioeconomic status and genetics on risk for metabolic disease. We analyzed data from the Mexican American Family Studies (MAFS) to evaluate the hypothesis that genotype-by-environment interaction (GxE) is an essential determinant of variation in risk factors for metabolic syndrome (MS).

Methods: We employed a maximum likelihood estimation of the decomposition of variance components to detect GxE interaction. After excluding individuals with diabetes and individuals on medication for diabetes, hypertension, or dyslipidemia, we …

Dysregulated Creb3 Cleavage At The Nuclear Membrane Induces Karyoptosis-Mediated Cell Death, Ga-Eun Lee, Geul Bang, Jiin Byun, Cheol-Jung Lee, Weidong Chen, Dohyun Jeung, Hyun-Jung An, Han Chang Kang, Dae Joon Kim, Megan Keniry

School of Medicine Publications and Presentations

Cancer cells often exhibit resistance to apoptotic cell death, but they may be vulnerable to other types of cell death. Elucidating additional mechanisms that govern cancer cell death is crucial for developing new therapies. Our research identified cyclic AMP-responsive element-binding protein 3 (CREB3) as a crucial regulator and initiator of a unique cell death mechanism known as karyoptosis. This process is characterized by nuclear shrinkage, deformation, and the loss of nuclear components following nuclear membrane rupture. We found that the N-terminal domain (aa 1-230) of full-length CREB3 (CREB3-FL), which is anchored to the nuclear inner membrane (INM), interacts with lamins …

Tgf-Β Signaling Pathways In The Development Of Diabetic Retinopathy, Andrew Callan, Sonal V. Jha, Laura Garcia, Lois F. Baldado, Andrew Tsin

School of Medicine Publications and Presentations

Diabetic retinopathy (DR), a prevalent complication of diabetes mellitus affecting a significant portion of the global population, has long been viewed primarily as a microvascular disorder. However, emerging evidence suggests that it should be redefined as a neurovascular disease with multifaceted pathogenesis rooted in oxidative stress and advanced glycation end products. The transforming growth factor-β (TGF-β) signaling family has emerged as a major contributor to DR pathogenesis due to its pivotal role in retinal vascular homeostasis, endothelial cell barrier function, and pericyte differentiation. However, the precise roles of TGF-β signaling in DR remain incompletely understood, with conflicting reports on its …

Genetic Correlations Between Liver Fat Content, Metabolic Health, And Adiposity Distribution In The Fels Longitudinal Study, Ariana L. Garza, Miryoung Lee, John Blangero, Cici X. Bauer, Stefan A. Czerwinski, Audrey C. Choh

School of Medicine Publications and Presentations

Highlights

• Steatosis and all other related phenotypes examined were significantly heritable.

• Liver fat showed significant genetic correlation with various phenotypes.

• The strongest genetic correlation of liver fat was with insulin resistance.

• Glucose homeostasis phenotypes were also genetically correlated to adiposity traits.

Abstract

Background and aims

Hepatic steatosis is known to be heritable, but its genetic basis is mostly uncharacterized. Steatosis is associated with metabolic and adiposity features; recent studies hypothesize that shared genetic effects between these traits could account for some of the unexplained heritability. This study aimed to quantify these genetic associations in a family-based sample of non-Hispanic white …

Genome-wide association studies of human personality have been carried out, but transcription of the whole genome has not been studied in relation to personality in humans. We collected genome-wide expression profiles of adults to characterize the regulation of expression and function in genes related to human personality. We devised an innovative multi-omic approach to network analysis to identify the key control elements and interactions in multi-modular networks. We identified sets of transcribed genes that were co-expressed in specific brain regions with genes known to be associated with personality. Then we identified the minimum networks for the co-localized genes using bioinformatic …
