Effective Interventions For Women With Post-Traumatic Stress Disorder, Kathryn Antoinette Gonzales

Electronic Theses, Projects, and Dissertations

Women diagnosed with post-traumatic stress disorder (PTSD) often undergo powerless treatment interventions according to research. Institutionalized inequalities among service systems challenge women to receive access, begin, engage, and complete mental health services for PTSD. This mixed-methods systematic review sought to determine interventions that are effective for treating this client population. The preferred reporting items for systematic reviews and meta-analysis (PRISMA) tool was used to screen four different electronic databases: PsycINFO, Google Scholar, EBSCO, and OneSearch to identify peer-reviewed articles under a purposive sampling method strategy. Of the 159 studies screened, 15 met the inclusion criteria for this review (n =15). …

Advanced maternal age (AMA) is defined as a pregnancy in a woman older than 35 years of age. AMA increases the risk for both maternal and neonatal complications, including miscarriage and stillbirth. AMA has also been linked to neurodevelopmental and neuropsychiatric disorders in the offspring. Recent studies have found that age-associated compositional shifts in the gut microbiota contribute to altered microbial metabolism and enhanced inflammation in the host. We investigated the specific contribution of the maternal microbiome on pregnancy outcomes and offspring behavior by recolonizing young female mice with aged female microbiome prior to pregnancy. We discovered that pre-pregnancy colonization …

Postoperative atrial fibrillation (poAF) is AF occurring days after surgery, with a prevalence of 33% among patients undergoing open-heart surgery. The degree of postoperative inflammation correlates with poAF risk, but less is known about the cellular and molecular mechanisms driving postoperative atrial arrhythmogenesis. We performed single-cell RNA-seq comparing atrial nonmyocytes from mice with and without poAF, which revealed infiltrating CCR2+ macrophages to be the most altered cell type. Pseudotime trajectory analyses identified Il-6 as a gene of interest driving in macrophages, which we confirmed in pericardial fluid collected from human patients after cardiac surgery. Indeed, macrophage depletion and macrophage-specific Il6ra …

Osteoarthritis is the third most rapidly growing health condition associated with disability, after dementia and diabetes1. By 2050, the total number of patients with osteoarthritis is estimated to reach 1 billion worldwide2. As no disease-modifying treatments exist for osteoarthritis, a better understanding of disease aetiopathology is urgently needed. Here we perform a genome-wide association study meta-analyses across up to 489,975 cases and 1,472,094 controls, establishing 962 independent associations, 513 of which have not been previously reported. Using single-cell multiomics data, we identify signal enrichment in embryonic skeletal development pathways. We integrate orthogonal lines of evidence, including …

Objectives: Circulating Epstein-Barr virus antibodies (EBV-Ab) are used as a biomarker of chronic stress in high-income settings, but their relevance in environments with a high burden of infectious disease, nutritional constraints, and limited resources is less clear. We investigated EBV-Ab as a biomarker of adversity in a setting where local ecology and economy may affect immune development differently than in wealthy countries.

Methods: We measured EBV-Ab in finger-prick dried blood spots collected from Indigenous Shuar (n = 433) and non-Indigenous Colonos (n = 84) ranging from < 1 to 87 years old in Amazonian Ecuador. For a subset of adults (≥ 15 years, n = 210), we collected socioeconomic information (income, education, and occupation) and assessed household-level market integration. We determined the most important predictors of EBV-Ab for adults and children using multi-model averaging of linear regression models.

Results: Male children (< 15 years) had lower EBV-Ab than female children (model averaged β [SE]: -0.238 [0.066]). For adults, Shuar had higher EBV-Ab than Colonos (model averaged β [SE]: 0.235 [0.113]), and high systolic blood pressure was an important predictor of elevated EBV-Ab (model averaged β [SE]: 0.088 [0.047]). Individuals who reported unpaid domestic work as their primary occupation had higher EBV-Ab than agricultural workers (model averaged β [SE]: 0.302 [0.113]). Individuals living in houses with more market-sourced infrastructure had lower EBV-Ab (model averaged β [SE]: -0.088 [0.068]).

Conclusions: Circulating EBV-Ab may capture context-specific aspects of socioecological adversity …

Patient-centered outcomes, including patient-reported outcomes (PROs), are increasingly important in healthcare and research, though their use in rare diseases remains limited. In disorders with significant phenotypic variation, selecting appropriate outcome measures is crucial to ensuring the relevance of clinical trials for the patient population. Phosphomannomutase 2-CDG (PMM2-CDG) involves a complex genotype-phenotype relationship, making it challenging to predict clinical outcomes and select reliable measures for clinical trials. Caused by biallelic pathogenic variants in the PMM2, PMM2-CDG displays highly variable clinical severity, underscoring the need for personalized outcome measures. One such so far unexplored, individualized approach is Goal Attainment Scaling (GAS), which …

Regulation Of Tfeb In Human Placental Cytotrophoblasts And Syncytiotrophoblasts, A Mathew, J S Trausch-Azar, C Azar, M Schuetz, M R Mahjoub, A L Schwartz

2020-Current year OA Pubs

While cellular proteins exist in a dynamic state maintained by the balance of synthesis and degradation, there is a paucity of information on these processes in placental trophoblasts, including within cytotrophoblasts which differentiate into multi-nucleate syncytiotrophoblasts. TFEB, a transcription factor with a myriad of cellular activities, is one of the most abundant genes expressed in syncytiotrophoblasts compared to cytotrophoblasts. TFEB is localized to the nucleus of human BeWo differentiated syncytiotrophoblasts and to the cytoplasm of the undifferentiated cytotrophoblasts. Within both the cytotrophoblasts and syncytiotrophoblasts, TFEB exists in subcellular compartments as both phosphorylated and unphosphorylated forms and translocates between cytoplasm and …

Leptomeningeal metastases are the major source of morbidity and mortality for patients with medulloblastoma. The biology of the leptomeningeal metastases and the local tumour microenvironment are poorly characterized. Here we show that metastasis-associated meningeal fibroblasts (MB-MAFs) are transcriptionally distinct and signal extensively to tumour cells and the tumour microenvironment. Metastatic cells secrete platelet-derived growth factor (PDGF) ligands into the local microenvironment to chemotactically recruit meningeal fibroblasts. Meningeal fibroblasts are reprogrammed to become MB-MAFs, expressing distinct transcriptomes and secretomes, including bone morphogenetic proteins. Active bone morphogenetic protein signalling and co-implantation of tumour cells with MB-MAFs enhances the colonization of the leptomeninges …

Cortical Structure In Nodes Of The Default Mode Network Estimates General Intelligence, Abhinav Yadav, Archana Purushotham

Faculty, Staff and Students Publications

Introduction: A growing number of studies implicate functional brain networks in intelligence, but it is unclear if network nodal structure relates to intelligence.

Methods: Using MRI, we studied the relationship of the general intelligence factor (g) with cortical thickness (CT), local gyrification index (LGI), and voxel-based morphometry in the nodes of the default mode network (DMN) and task-positive network (TPN) in a cohort of 44 young, healthy adults. Employing a novel strategy, we performed repeated analyses with multiple sets of g estimates to remove false positives.

Results: CT and LGI in medial and temporal nodes of the DMN were reliably …

Widespread Pain Phenotypes Impact Treatment Efficacy Results In Randomized Clinical Trials For Interstitial Cystitis/Bladder Pain Syndrome: A Multidisciplinary Approach To The Study Of Chronic Pelvic Pain Network Study, John T. Farrar, Siobhan Sutcliffe, Et Al.

2020-Current year OA Pubs

Pain clinical trials are notoriously complex and often inefficient in demonstrating efficacy, even for known efficacious treatments. A major issue is the difficulty in the a priori identification of specific phenotypes to include in the study population. Recent work has identified the extent of widespread pain as an important determinant of the likelihood of response to therapy, but it has not been tested in clinical trials for the treatment of interstitial cystitis/bladder pain syndrome (IC/BPS). We explored this hypothesis using data from 3 previously published trials testing treatments for IC/BPS, which suggested modest benefits but did not meet a priori …

Multi-Omic And Spatial Analysis Of Mouse Kidneys Highlights Sex-Specific Differences In Gene Regulation Across The Lifespan, Siqi Chen, Ruiyang Liu, Chia-Kuei Mo, Michael C Wendl, Andrew Houston, Preet Lal, Yanyan Zhao, Wagma Caravan, Andrew T Shinkle, Atieh Abedin-Do, Nataly Naser Al Deen, Kazuhito Sato, Xiang Li, André Luiz N Targino Da Costa, Yize Li, Alla Karpova, John M Herndon, Maxim N Artyomov, Joshua B Rubin, Sanjay Jain, Sheila A Stewart, Li Ding, Feng Chen, Et Al.

There is a sex bias in the incidence and progression of many kidney diseases. To better understand such sexual dimorphism, we integrated data from six platforms, characterizing 76 kidney samples from 68 mice at six developmental and adult time points, creating a molecular atlas of the mouse kidney across the lifespan for both sexes. We show that proximal tubules have the most sex-biased differentially expressed genes emerging after 3 weeks of age and are associated with hormonal regulations. We reveal potential mechanisms involving both direct and indirect regulation by androgens and estrogens. Spatial profiling identifies distinct sex-biased spatial patterns in …

Social Anxiety Moderates The Association Between Adolescent Irritability And Bully Perpetration, Michael T Perino, Jennifer C Harper-Lednicky, Alecia C Vogel, Chad M Sylvester, Deanna M Barch, Joan L Luby

2020-Current year OA Pubs

BACKGROUND: Preliminary work suggests anxiety moderates the relationship between irritability and bullying. As anxiety increases, the link between irritability and perpetration decreases. We hypothesize that any moderation effect of anxiety is driven by social anxiety symptoms. We sought to explicate the moderating effect of anxiety, while clarifying relations to other aggressive behaviors.

METHODS: A sample of adolescents (

RESULTS: Irritability was significantly related to bullying (

CONCLUSIONS: Understanding how psychopathology interacts with social behaviors is of great importance. Higher social anxiety is linked to reduced relations between irritability and bullying; however, the link between irritability and other aggression remains positive. …

Meningomyelocele (also known as spina bifida) is considered to be a genetically complex disease resulting from a failure of the neural tube to close. Individuals with meningomyelocele display neuromotor disability and frequent hydrocephalus, requiring ventricular shunting. A few genes have been proposed to contribute to disease susceptibility, but beyond that it remains unexplained1. We postulated that de novo mutations under purifying selection contribute to the risk of developing meningomyelocele2. Here we recruited a cohort of 851 meningomyelocele trios who required shunting at birth and 732 control trios, and found that de novo likely gene disruption or …

Plasma p-tau217 and tau positron emission tomography (PET) are strong prognostic biomarkers in Alzheimer's disease (AD), but their relative performance in predicting future cognitive decline among cognitively unimpaired (CU) individuals is unclear. In a head-to-head comparison study including nine cohorts and 1,474 individuals, we show that plasma p-tau217 and medial temporal lobe tau-PET signal display similar associations with cognitive decline on a global cognitive composite test (R

High-Dimensional Mediation Analysis For Longitudinal Mediators And Survival Outcomes, Lili Liu, Haixiang Zhang, Yinan Zheng, Tao Gao, Cheng Zheng, Kai Zhang, Lifang Hou, Lei Liu

2020-Current year OA Pubs

Mediation analysis with high-dimensional mediators is crucial for identifying epigenetic pathways linking environmental exposures to health outcomes. However, high-dimensional mediation analysis methods for longitudinal mediators and a survival outcome remain underdeveloped. This study fills that gap by introducing a method that captures mediation effects over time using multivariate, longitudinally measured time-varying mediators. Our approach uses a longitudinal mixed effects model to examine the relationship between the exposure and the mediating process. We connect the mediating process to the survival outcome using a Cox proportional hazards model with time-varying mediators. To handle high-dimensional data, we first employ a mediation-based sure independence …

Background: Alterations in brain function and structure, such as depression and neurocognitive impairment, continue to occur in people with human immunodeficiency virus (HIV, PWH) taking suppressive antiretroviral therapy (ART). The lifespan of PWH has improved but the healthspan remains worse than people without HIV, in part because of aging-related diseases. As a result, polypharmacy is common and increases the risk of drug-drug interactions and adverse reactions.

Methods: This cross-sectional project investigated the relationship between 7 medication-related metrics (including anticholinergic burden), depressive symptoms, and neurocognitive performance in 491 PWH at a single center in the United States. All participants were taking …

Engineering broadly neutralizing monoclonal antibodies (mAbs) targeting the hemagglutinin (HA) of Influenza A virus (IAV) is a promising approach for intervention of seasonal flu. However, HA plasticity often leads to resistant strains that compromise mAb potency as bivalent IgGs. Here we hypothesize that multimerization of anti-IAV antibodies as IgMs can enhance coverage and neutralization potency. Here, we construct 18 IgM antibodies from known broadly neutralizing IgGs targeting different IAV HA epitopes and evaluate their breadth and potency of neutralization against distinct H1N1 and H3N2 IAVs. The IgM version of receptor binding site-specific IgG F045-092 shows increased breadth and antiviral potency …

The cerebellar ventricular zone (VZ) is the primary source of progenitors that generate cerebellar GABAergic neurons, including Purkinje cells (PCs) and interneurons (INs). This study provides detailed characterization of human cerebellar GABAergic neurogenesis using transcriptomic and histopathological analyses and reveals conserved and unique features compared to rodents. We show that the sequential progression of neurogenesis is conserved and occurs before 8 postconception weeks. Notably, PC differentiation occurs in the outer subventricular zone (SVZ), a region absent in the mouse cerebellum. Human PCs are generated during a compact two-week period before the onset of cerebral cortex histogenesis. A subset of human …

Background: Approximately 20% of all transient ischaemic attacks (TIAs) and ischaemic strokes occur within the posterior circulation, with vertebrobasilar stenosis identified as the cause in roughly 25% of the cases. Studies have shown that about a quarter of these patients have atherosclerotic stenosis of at least 50% of the vertebrobasilar artery. Stenosis has been shown to be associated with an increased risk of 90-day recurrent vertebrobasilar stroke, particularly in the first few weeks, which is significantly higher when compared with patients with stenosis of the anterior circulation. Therefore, aggressive treatment is important for the patient's prognosis. Stenting is emerging as …
