Obsessive-compulsive disorder (OCD) and posttraumatic stress disorder (PTSD) share overlapping features for which similar cognitive behavioral treatment (CBT) strategies can be employed. However, the comorbid presence of these conditions poses unique clinical considerations, and a nuanced approach to assessment, conceptualization, and treatment is needed when working with individuals with co-occurring OCD and PTSD. Treatment providers may not be aware of these nuances and may hold misconceptions about co-occurring OCD and PTSD, impacting their approach to assessment, conceptualization, and treatment. The current study sought to examine possible misconceptions among mental health treatment providers of differing specializations. Among 146 primarily CBT-oriented treatment …

Antibiotic Prophylaxis With Urodynamic Studies In Spinal Cord Injury: Assessing Practice Patterns And Outcomes To Guide Future Practice In A Single Center, Du Pham, Bradley Chi, Felicia Skelton, Donna Huang

Faculty, Staff and Students Publications

Context/objective: Despite urinary tract infections (UTIs) being a common problem in patients with spinal cord injuries (SCIs), and a well-known complication of invasive urologic procedures, little consensus exists regarding the standard of care for peri-procedural antibiotic use for SCI patients undergoing urodynamics studies (UDS). Our research seeks to evaluate local antibiotic prophylaxis pattern in SCI patients undergoing UDS, assess incidence of post-procedural UTI, describe local antibiotic resistance trends, and provide antibiotic stewardship considerations to guide future practice.

Design/setting/participants: Retrospective cohort study of SCI patients undergoing UDS from January 2010 to January 2020 at a Veterans Affairs SCI Center. Data on …

Repeat Ascaris Challenge Reduces Worm Intensity Through Gastric Cellular Reprograming, Yifan Wu, Charlie Suarez-Reyes, Nina L Tang, Alexander R Kneubehl, Jill E Weatherhead

Faculty, Staff and Students Publications

Ascariasis (roundworm) is the most prevalent parasitic nematode infection worldwide, impacting approximately 500 million people predominantly in low- and middle-income countries (LMICs). While people of all ages are infected with Ascaris, infection intensity (defined by worm burden) paradoxically peaks in pre-school and school-aged children but then declines with age. The cause of age-dependent Ascaris worm intensity is not well understood but may be dependent on cellular changes in mucosal barrier sites. We have previously found that the gastric mucosa is a critical barrier site for Ascaris infection as ingested Ascaris larvae use acidic mammalian chitinase (AMCase) secreted by gastric chief …

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 …

The Small Gtpase Rap1 In Pomc Neurons Regulates Leptin Actions And Glucose Metabolism, Kentaro Kaneko, Weisheng Lu, Yong Xu, Alexei Morozov, Makoto Fukuda

Faculty, Staff and Students Publications

The hypothalamic leptin-proopiomelanocortin (POMC) pathway is critical for regulating metabolism. POMC neurons in the arcuate nucleus respond to leptin and play a pivotal role in mediating energy and glucose balance. However, during diet-induced obesity (DIO), these neurons often develop resistance to exogenous leptin. Recently, the small GTPase Rap1 has been implicated as an inhibitor of neuronal leptin signaling; however, its specific role within POMC neurons remains unexplored. We generated tamoxifen-inducible, POMC neuron-specific Rap1 knockout mice to selectively delete both Rap1a and Rap1b isoforms in POMC neurons. By analyzing these mice through metabolic phenotyping, immunohistochemistry, and biochemical assays, we show that …

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 …

Germ cell tumors of the testis (GCTs) provide an ideal tumor model to investigate the cellular versus genetic origin of cancers. In this single institutional study, we evaluated 38 patients with bilateral GCT, including tumors that occurred simultaneously (synchronous) and those occurring at different times (metachronous). For nine of these patients, DNA was isolated from the right and left GCT to determine the genomic and epigenetic differences between tissues using whole-exome sequencing (WES) and reduced representation bisulfite sequencing (RRBS). We found that seminomas and non-seminomas are molecularly distinct based on DNA methylation and not due to synchronous or metachronous disease. …

Network-Based Clustering Unveils Interconnected Landscapes Of Genomic And Clinical Features Across Myeloid Malignancies, Fritz Bayer, Marco Roncador, Giusi Moffa, Kiyomi Morita, Koichi Takahashi, Niko Beerenwinkel, Jack Kuipers

Faculty, Staff and Student Publications

Myeloid malignancies exhibit considerable heterogeneity with overlapping clinical and genetic features among subtypes. We present a data-driven approach that integrates mutational features and clinical covariates at diagnosis within networks of their probabilistic relationships, enabling the discovery of patient subgroups. A key strength is its ability to include presumed causal directions in the edges linking clinical and mutational features, and account for them aptly in the clustering. In a cohort of 1323 patients, we identify subgroups that outperform established risk classifications in prognostic accuracy. Our approach generalises well to unseen cohorts with classification based on our subgroups similarly offering advantages in …

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 …

Distinct Oxytocin Signaling Pathways Synergistically Mediate Rescue-Like Behavior In Mice, Feng-Rui Zhang, Juan Liu, Jieqi Wen, Zi-Yan Zhang, Yijia Li, Eric Song, Li Hu, Zhou-Feng Chen

2020-Current year OA Pubs

Spontaneous rescue behavior enhances the well-being and survival of social animals, yet the neural mechanisms underlying the recognition and response to conspecifics in need remain unclear. Here, we report that observer mice experience distress when encountering anesthetized conspecifics, prompting spontaneous rescue-like behavior toward the unconscious mice. This behavior facilitates the earlier awakening of anesthetized mice while simultaneously alleviating stress in the helper mice. Our findings reveal that endogenous oxytocin (OXT) release from the hypothalamic paraventricular nucleus (PVN) to the oxytocin receptor (OXTR) in the central nucleus of the amygdala (CeA) regulates the emotional component of rescue-like behavior. In contrast, OXT …

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 …

Place-Based Harms And Hidden Strengths: A Qualitative Study Exploring Facets Of Neighborhood Disinvestment Driving Opioid Overdose Among Black Individuals, Kaytryn D Campbell, Rachel P Winograd, Maria E Paschke, Alex Duello, Devin E Banks

2020-Current year OA Pubs

BACKGROUND: Despite significant efforts to address the opioid overdose crisis, Black people who use drugs (PWUD) face unabating, disproportionate increases in opioid overdose death (OOD) rates. These inequities persist in treatment admissions, utilization of medication for opioid use disorder, and treatment retention. Research has linked neighborhood disinvestment - a process of urban decline driven by policy-related changes in neighborhood demand and desirability leading to decreased population, physical and economic erosion, and poorer quality of life for residents - to increased rates of OOD. However, given recent increases in OOD inequities, more research is needed to determine the specific aspects of …
