A Scoping Review Of The Associations Between Ascariasis, Helicobacter Pylori Infection And Gastric Pathologies, Nina L Tang, Jacob J Williams, Jennifer Stockton, Maria Elena Bottazzi, Jill E Weatherhead

Library Staff Publications

Ascaris infection-ascariasis-is the most common human parasitic worm infection worldwide and induces damage and cellular changes within the stomach. Helicobacter pylori is a bacterium of the stomach that also causes gastric pathologies globally. Importantly, Ascaris, H. pylori, and gastric diseases all disproportionately affect individuals in resource-limited settings. However, the associations between ascariasis, H. pylori infection, and gastric diseases remain relatively unexplored. We synthesized the existing research associating Ascaris infection with H. pylori infection and/or gastric pathologies. Records were identified in OVID Medline, Embase and Web of Science using search terms for ascariasis, H. pylori infection, and gastric abnormalities and additional …

Faculty, Staff and Students Publications

Background: Mendelian randomization studies suggest a causal effect of lipoprotein(a) (Lp(a)) on atherosclerotic cardiovascular disease. Noncardiovascular effects (eg, diabetes risk) are inadequately investigated.

Objectives: In this noninterventional phenome-wide association study designed to better understand the potential causal role of Lp(a), direct causal phenotypic effects of exposure to Lp(a) were estimated. Also, the association between LPA null allele rs41272114 with type 2 diabetes was assessed, and ancestry-specific Lp(a) thresholds were determined.

Methods: In the UK Biobank (n = 425,677 adults, 55% female), we studied 1,456 phenotypes spanning 18 classes using 4 ancestry-specific polygenic risk scores and false discovery rate multiple testing …

Fructose: Metabolic Signal And Modern Hazard, Richard J Johnson, Miguel A Lanaspa, Dean R Tolan, Marcus D Goncalves, Samir Softic, Kimber L Stanhope, Laura G Sánchez-Lozada, Mark A Herman, Joshua D Rabinowitz

Faculty, Staff and Students Publications

There is much interest in the role of sweeteners such as table sugar (sucrose) and high-fructose corn syrup in obesity and metabolic disease. Both sweeteners consist of glucose and fructose, two six-carbon isomeric sugars. Whereas glucose ingestion may promote obesity through its effects to stimulate insulin secretion, fructose has unique metabolic effects that promote triglyceride synthesis and fat accumulation. These effects arise from fructose's well-known role as a signal of metabolic plenty. Under modern conditions of overnutrition, chronic excess fructose drives features of metabolic syndrome. Emerging evidence further links fructose to cancer and dementia. Here we review the biochemical, molecular …

Case Series: Joubert Syndrome And Eosinophilic Esophagitis, Jonathon Schening, Stephanie Leon-Paredes, Eric Chiou, Vibha Szafron, Anthony Olive, Sara Anvari

Faculty, Staff and Students Publications

Joubert syndrome (JS) is a rare genetic disorder characterized by developmental abnormalities, particularly in the brainstem and cerebellar vermis, alongside multisystem manifestations such as kidney and liver anomalies, polydactyly, cleft lip or palate, and tongue defects. The underlying ciliopathy causing JS may also contribute to gastrointestinal symptoms and immune dysregulation via Wnt signaling and impaired epithelial maintenance. Dysmotility including Hirschsprung disease has been documented at increased rates in JS and in other ciliopathies. Our case series highlights how JS patients frequently exhibit feeding intolerance, vomiting, and poor growth, which may raise suspicion for an underlying gastrointestinal condition, such as eosinophilic …

Background: Relapsed medulloblastoma remains a significant therapeutic challenge as it is near universally fatal. The tumor microenvironment of medulloblastoma plays a critical role in tumor progression, influencing tumor growth, immune evasion, and therapeutic resistance. We hypothesized that defining tumor-immune interactions in diagnostic and relapsed medulloblastoma may uncover mechanisms of immune evasion and identify novel therapeutic targets.

Methods: We analyzed paired primary and recurrent RNA-sequencing data from 140 medulloblastoma patients to profile immune cell composition and validate spatial relationships within the TME. To identify key tumor-immune interactions, we developed a novel algorithm to detect receptor-ligand pairs using single-cell RNA-sequencing data. These …
