School of Social Work Faculty Publications

The COVID-19 pandemic changed people’s lives and resulted in tremendous pain, loss and suffering. The Rio Grande Valley (RGV), in the state of Texas in the U.S., was one of the regions with the highest number of infections and deaths during the pandemic. However, individuals’ bereavement in the RGV is rarely addressed. In this qualitative study, a snowball sample of 47 individuals who had lost their loved ones during the years 2020–2021 were interviewed and invited to engage in an art activity. The findings revealed four themes: peculiar funeral, grieving confusion, loved ones’ memories, and connection to self and the …

Viability Discrimination Of Bacterial Microbiomes In Home Kitchen Dish Sponges Using Propidium Monoazide Treatment, Christina K Carstens, Joelle K Salazar, Shreela Sharma, Wenyaw Chan, Charles Darkoh

Faculty, Staff and Student Publications

Dish sponges are known to support the proliferation of human bacterial pathogens, yet they are commonly used by consumers. Exposure to foodborne pathogens via sponge use may lead to illness, a serious concern among susceptible populations. The extent of exposure risks from sponge use has been limited by constraints associated with culture-independent or dependent methods for bacterial community characterization. Therefore, five used dish sponges were characterized to evaluate the presence of viable bacterial foodborne pathogens using the novel application of propidium monoazide (PMA) treatment and targeted 16S rRNA gene amplicon sequencing. Select pathogen viability was confirmed using targeted selective enrichment. …

Regulation Of Fibrinogen Synthesis, Dre'von A Dobson, Richard J Fish, Paul S De Vries, Alanna C Morrison, Marguerite Neerman-Arbez, Alisa S Wolberg

Faculty, Staff and Student Publications

The plasma protein fibrinogen is encoded by 3 structural genes (FGA, FGB, and FGG) that are transcribed to mRNA, spliced, and translated to 3 polypeptide chains (Aα, Bβ, and γ, respectively). These chains are targeted for secretion, decorated with post-translational modifications, and assembled into a hexameric “dimer of trimers” (AαBβγ)2. Fully assembled fibrinogen is secreted into the blood as a 340 kDa glycoprotein. Fibrinogen is one of the most prevalent coagulation proteins in blood, and its expression is induced by inflammatory cytokines, wherein circulating fibrinogen levels may increase up to 3-fold during acute inflammatory events. Abnormal …

Ficture: Scalable Segmentation-Free Analysis Of Submicron-Resolution Spatial Transcriptomics, Yichen Si, Changhee Lee, Yongha Hwang, Jeong H Yun, Weiqiu Cheng, Chun-Seok Cho, Miguel Quiros, Asma Nusrat, Weizhou Zhang, Goo Jun, Sebastian Zöllner, Jun Hee Lee, Hyun Min Kang

Faculty, Staff and Student Publications

Spatial transcriptomics (ST) technologies have advanced to enable transcriptome-wide gene expression analysis at submicron resolution over large areas. However, analysis of high-resolution ST is often challenged by complex tissue structure, where existing cell segmentation methods struggle due to the irregular cell sizes and shapes, and by the absence of segmentation-free methods scalable to whole-transcriptome analysis. Here we present FICTURE (Factor Inference of Cartographic Transcriptome at Ultra-high REsolution), a segmentation-free spatial factorization method that can handle transcriptome-wide data labeled with billions of submicron-resolution spatial coordinates and is compatible with both sequencing-based and imaging-based ST data. FICTURE uses the multilayered Dirichlet model …

Introduction: Clonal hematopoiesis of indeterminate potential (CHIP) and dementia disproportionately burden patients with chronic kidney disease (CKD). The association between CHIP and cognitive impairment in CKD patients is unknown.

Methods: We conducted time-to-event analyses in up to 1452 older adults with CKD from the Chronic Renal Insufficiency Cohort who underwent CHIP gene sequencing. Cognition was assessed using four validated tests in up to 6 years mean follow-up time. Incident cognitive impairment was defined as a test score one standard deviation below the baseline mean.

Results: Compared to non-carriers, CHIP carriers were markedly less likely to experience impairment in attention (adjusted …

Lps-Induced Whole-Blood Cytokine Production And Depressive Symptoms In Dementia Spousal Caregivers: The Moderating Effect Of Childhood Trauma, Daniel L Argueta, Kelly N Brice, E Lydia Wu-Chung, Michelle A Chen, Vincent D Lai, Jensine Paoletti-Hatcher, Bryan T Denny, Charles Green, Luis D Medina, Paul Schulz, Jennifer Stinson, Cobi Heijnen, Christopher P Fagundes

Faculty, Staff and Student Publications

Dementia spousal caregivers are at risk for adverse mental and physical health outcomes. Caregiver burden, anticipatory grief, and proinflammatory cytokine production may contribute to depressive symptoms among caregivers. People who report childhood trauma are more likely to have exaggerated stress responses that may also contribute to depressive symptoms in adulthood. This study aimed to test whether the relationship between whole-blood cytokine production and depressive symptoms is strongest in caregivers who report high levels of childhood trauma.

Methods: A sample of 103 dementia spousal caregivers provided self-report data on demographics, health information, caregiver burden, anticipatory grief, and depressive symptoms. We also …

Hippocampal Gray Matter Volume In Young Adulthood Varies With Adolescent Alcohol Use, Juliann B Purcell, Nathaniel G Harnett, Sylvie Mrug, Marc N Elliott, Susan Tortolero Emery, Mark A Schuster, David C Knight

Faculty, Staff and Student Publications

Adolescent substance use is linked with negative future outcomes (e.g., depression, anxiety, substance use disorder). Given that the brain undergoes significant maturation during adolescence, this developmental period may represent a time of particular vulnerability to substance use. Neuroimaging research has largely focused on heavy or binge patterns of substance use; thus, relatively less is known about the neural impact of a broader range of adolescent substance use. Characterizing the neural impact of a broader range of adolescent substance use may inform prevention and treatment efforts. The present study investigated relationships between adolescent substance use trajectories (i.e., alcohol, tobacco, and cannabis) …

Pparγ/Etv2 Axis Regulates Endothelial-To-Mesenchymal Transition In Pulmonary Hypertension, Dong Hun Lee, Minseong Kim, Sarah S Chang, Raham Lee, Andrew J Jang, Juyoung Kim, Jing Ma, Michael J Passineau, Raymond L Benza, Harry Karmouty-Quintana, Wilbur A Lam, Benjamin T Kopp, Roy L Sutliff, C Michael Hart, Changwon Park, Bum-Yong Kang

Faculty, Staff and Student Publications

Endothelial-to-mesenchymal transition (EndoMT) plays an important role in pulmonary hypertension (PH) but the molecular mechanisms regulating EndoMT remain to be defined. We demonstrate that the axis of the transcription factors PPARγ (Peroxisome Proliferator-Activated Receptor gamma) and ETV2 (ETS variant 2) play important roles in the pathogenesis of PH. Decreased levels of the expression of PPARγ and ETV2 along with reduced endothelial and increased EndoMT markers are consistently observed in lungs and pulmonary artery endothelial cells (PAECs) of idiopathic pulmonary arterial hypertension patients, in hypoxia-exposed mouse lungs, human PAECs, and in induced-EndoMT cells. Etv2 +/- mice spontaneously developed PH and right …

Faculty, Staff and Student Publications

Prior cohort studies assessing cancer risk based on immune cell subtype profiles have predominantly focused on White populations. This limitation obscures vital insights into how cancer risk varies across race. Immune cell subtype proportions were estimated using deconvolution based on leukocyte DNA methylation markers from blood samples collected at baseline on participants without cancer in the Atherosclerosis Risk in Communities Study. During a mean of 17.5 years of follow-up, 668 incident cancers were diagnosed in 2,467 Black participants. Cox proportional hazards regression was used to examine immune cell subtype proportions and overall cancer incidence and site-specific incidence (lung, breast, and …

Anxiety is the most prevalent mental health disorder among adults worldwide. Given its increased prevalence among migrants due to their marginalized position in the societies where they reside, psychometric evaluations of anxiety measures such as the Generalized Anxiety Disorder-7 (GAD-7) are needed for use with migrants. The present study is the first attempt to compare the structure of GAD-7 scores for (a) different Latino groups in the same country and (b) the same Latino group in two different countries. Using three samples of Mexican and Venezuelan migrants (total N = 933), we provide reliability and validity evidence of the GAD-7 …

The Five Homologous Ciar-Controlled Ccn Srnas Of Streptococcus Pneumoniae Modulate Zn-Resistance, Nicholas R De Lay, Nidhi Verma, Dhriti Sinha, Abigail Garrett, Maximillian K Osterberg, Daisy Porter, Spencer Reiling, David P Giedroc, Malcolm E Winkler

Faculty, Staff and Student Publications

Zinc is a vital transition metal for all bacteria; however, elevated intracellular free Zn levels can result in mis-metalation of Mn-dependent enzymes. For Mn-centric bacteria such as Streptococcus pneumoniae that primarily use Mn instead of Fe as an enzyme cofactor, Zn is particularly toxic at high concentrations. Here, we report our identification and characterization of the function of the five homologous, CiaRH-regulated Ccn sRNAs in controlling S. pneumoniae virulence and metal homeostasis. We show that deletion of all five ccn genes (ccnA, ccnB, ccnC, ccnD, and ccnE) from S. pneumoniae strains D39 (serotype 2) and TIGR4 (serotype 4) causes Zn …

Exploring The Relationship Between Intrinsic Motivation And Receptivity To Mhealth Interventions, Varun Mishra, Sarah Hong, David Kotz

Dartmouth Scholarship

Just-in-Time Adaptive Interventions aim to deliver the right type and amount of support at the right time. This involves determining a user's state of receptivity - the degree to which a user is willing to accept, process, and use the intervention. Although past work has found that users are more receptive to notifications they view as useful, there is no existing research on whether users' intrinsic motivation for the underlying topic of mHealth interventions affects their receptivity. To explore this, we conducted a study with 20 participants over three weeks, where participants interacted with a chatbot-based digital coach to receive …

Internal Medicine, East Africa

Background: Around the world, people living in objectively difficult circumstances who experience symptoms of generalized anxiety disorder (GAD) do not qualify for a diagnosis because their worry is not ‘excessive’ relative to the context. We carried out the first largescale, cross-national study to explore the implications of removing this excessiveness requirement.

Methods: Data come from the World Health Organization World Mental Health Survey Initiative. A total of 133 614 adults from 12 surveys in Low- or Middle-Income Countries (LMICs) and 16 surveys in High-Income Countries (HICs) were assessed with the Composite International Diagnostic Interview. Non-excessive worriers meeting all other DSM-5 …

Classification Of Isolated Versus Multiple Birth Defects: An Automated Process For Population-Based Registries, Renata H Benjamin, Joanne M Nguyen, Margaret Drummond-Borg, Angela E Scheuerle, Peter H Langlois, Mark A Canfield, Charles J Shumate, Laura E Mitchell, A J Agopian

Faculty, Staff and Student Publications

Epidemiologic studies of birth defects often conduct separate analyses for cases that have isolated defects (e.g., spina bifida only) and cases that have multiple defects (e.g., spina bifida and a congenital heart defect). However, in some instances, cases with additional defects (e.g., spina bifida and clubfoot) may be more appropriately considered as isolated because the co-occurring defect (clubfoot) is believed to be developmentally related to the defect of interest. Determining which combinations should be considered isolated can be challenging and potentially resource intensive for registries. Thus, we developed automated classification procedures for differentiating between isolated versus multiple defects, while accounting …

Methadone is a mu (μ) opioid receptor agonist used clinically in adults and children to manage opioid use disorder, neonatal abstinence syndrome, and acute and chronic pain. It is typically marketed as a racemic mixture of R- and S-enantiomers. R-methadone has 30-to 50-fold higher analgesic potency than S-methadone, and S-methadone has a greater adverse effect (prolongation) on the cardiac QTc interval. Methadone undergoes stereoselective metabolism. CYP2B6 is the primary enzyme responsible for catalyzing the metabolism of both enantiomers to the inactive metabolites, S- and R-2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine (S- and R-EDDP). Genetic variation in the CYP2B6 gene has been investigated in the context …

Phenotypic Diversity Of Type Iii Secretion System Activity In Enteropathogenic Escherichia Coli Clinical Isolates, Carmen A Contreras, Tracy H Hazen, Carmen Guadarrama, Ramón Cervantes-Rivera, Theresa J Ochoa, Pablo Vinuesa, David A Rasko, Jose L Puente

Faculty, Staff and Student Publications

Introduction. Enteropathogenic Escherichia coli (EPEC) strains pose a significant threat as a leading cause of severe childhood diarrhoea in developing nations. EPEC pathogenicity relies on the type III secretion system (T3SS) encoded by the locus of enterocyte effacement (LEE), facilitating the secretion and translocation of bacterial effector proteins.

Gap Statement. While the regulatory roles of PerC (plasmid-encoded regulator) and GrlA (global regulator of LEE-activator) in ler expression and LEE gene activation are well-documented in the EPEC prototype strain E2348/69, understanding the variability in LEE gene expression control mechanisms among clinical EPEC isolates remains an area requiring further investigation.

Parental Knowledge And Perception Of Obesity And Effect On Feeding Behavior And Child's Weight Status, Fidelia Senayah

Walden Dissertations and Doctoral Studies

Childhood obesity is a significant public health problem that leads to poor health outcomes in affected children, including the potential for developing chronic diseases in adulthood if not addressed at an early stage. While there are several studies on childhood obesity, data on parental obesity knowledge and risk perception as it relates to feeding behavior and child weight outcome is inadequate. No data were found on the topic in Ohio, which has a high rate of childhood obesity and overweight. This study examined how parental obesity risk knowledge and risk perception influenced parental feeding behavior and children’s weight status in …
