Hyperglycemia, Receptor For Advanced Glycation End Products, And Small Airways Dysfunction In Asthma, Paula Sierra Salas, Dennis T Villareal, Vickram Tejwani, Amrit Koirala, Cristian Coarfa, Meredith C Mccormack, Nicola A Hanania, Tianshi David Wu

Faculty, Staff and Students Publications

Background: Diabetes and insulin resistance are associated with higher risk of asthma exacerbation and preserved ratio impaired spirometry (PRISm), but the pathophysiology is unclear. These conditions may cause small airways dysfunction (SAD), which is an under-recognized cause of PRISm.

Objective: To determine whether insulin resistance and poor glucose control associate with SAD and to explore whether proteins prognostic of diabetes end-organ complications predict lung function abnormalities.

Methods: We recruited a prospective cohort of adults with physician-diagnosed asthma. Fasting insulin, glucose, hemoglobin A1c, and concentrations of 13 proteins prognostic of diabetes end-organ complications were measured. Static insulin resistance was calculated by …

Cressent: A Bioinformatics Toolkit To Explore And Improve Ssdna Virus Annotation, Ricardo R Pavan, Matthew B Sullivan, Michael J Tisza

Faculty, Staff and Students Publications

ssDNA viruses are important components of diverse ecosystems; however, it remains challenging to systematically identify and classify them. This is partly due to their broad host range and resulting genomic diversity, structure and rapid evolutionary rates. In addition, distinguishing genuine ssDNA genomes from contaminating sequences in metagenomic datasets (e.g. from commercial kits) has been an unresolved issue for years. Here, we present CRESSENT (CRESS-DNA Extended aNnotation Toolkit), a comprehensive and modular bioinformatic pipeline focused on ssDNA virus 'genome-to-analysis' and annotation. The pipeline integrates multiple functionalities organized into several modules: sequence dereplication, decontamination, phylogenetic analysis, …

Faculty, Staff and Students Publications

Background: Soil-transmitted helminths (STHs) are among the most common global parasitic infections, represent a significant worldwide public health burden, and remain a source of considerable morbidity in Latin America. Nematophagous fungi (NF), such as Arthrobotrys oligospora, naturally inhabit many soil types and are known for their ability to trap and kill nematodes using specialized hyphal structures or secreted enzymes and metabolites. As they prey on different developmental stages of helminths in soil, they may represent an ecological factor influencing helminth persistence and transmission dynamics.

Methods: Using an in vitro test, Toxocara cati eggs were exposed to A. oligospora. By using …

While respiratory diseases such as chronic obstructive pulmonary disease (COPD) and asthma share many risk factors, most studies investigate them in isolation and in predominantly European-ancestry populations. Here, we conducted the most powerful multi-trait and multi-ancestry genetic analysis of respiratory diseases and auxiliary traits to date, identifying 25 new loci associated with lung function in individuals of East Asian ancestry. Using these results, we developed PRSxtra (cross-trait and cross-ancestry), a multi-trait and multi-ancestry polygenic risk score (PRS) approach that leverages shared components of heritable risk via pleiotropic effects. PRSxtra significantly improved the prediction of asthma, COPD and lung cancer compared …

Faculty, Staff and Students Publications

Significance: Observing the activity of large populations of neurons in vivo is critical for understanding brain function and dysfunction. The use of fluorescent genetically encoded calcium indicators (GECIs) in conjunction with miniaturized microscopes is an exciting emerging toolset for recording neural activity in unrestrained animals. Despite their potential, current miniaturized microscope designs are limited using image sensors with low frame rates, sensitivity, and resolution. Beyond GECIs, there are many neuroscience applications that would benefit from the use of other emerging neural indicators, such as fluorescent genetically encoded voltage indicators (GEVIs) that have faster temporal resolution to match neuron spiking, yet …

Deep Brain Stimulation Response Circuits In Obsessive-Compulsive Disorder, Andreas Horn, Ningfei Li, Garance M Meyer, Ron Gadot, Nicole R Provenza, Sameer A Sheth

Faculty, Staff and Students Publications

In the field of deep brain stimulation (DBS), two major themes are currently making significant progress. First, the framework of connectomic DBS, in which circuits that are associated with improvements of specific symptoms are described and targeted to improve and potentially personalize treatment. Second, the concept of brain sensing and adaptive DBS, which aims at identifying neural biomarkers that may guide stimulation in a closed-loop fashion.

In DBS for Obsessive Compulsive Disorder (OCD), substantial progress has been made on both ends, over the last five years. Together, results begin to draw a picture of exactly which circuit is …

Faculty, Staff and Students Publications

Background: Medulloblastoma and ependymoma are common pediatric central nervous system tumors with significant molecular and clinical heterogeneity. While molecular subgrouping has enabled classification into molecular subtypes, the extent of heterogeneity within these subgroups remains poorly defined.

Methods: We collected bulk RNA sequencing data from 888 medulloblastoma and 370 ependymoma tumors to establish a comprehensive reference landscape. After rigorous batch effect correction, normalization, and dimensionality reduction, we generated a unified landscape to explore gene expression, signaling pathways, RNA fusions, and copy number variations.

Results: Our transcriptional analysis revealed distinct clustering patterns, including two primary ependymoma compartments, EPN-E1 and EPN-E2, each with …

The Hidden Link Between Endometriosis And Obesity: A State-Of-The-Art Review, Shefali N Desai, Christina C Reed, Yamely Mendez, Qiannan Yang, Xiaoming Guan

Faculty, Staff and Students Publications

Endometriosis remains an under-researched disease with a wide range of symptoms. Endometriosis reduces a woman's quality of life and professional productivity, yet its exact causes, risk factors, and treatment have yet to be elucidated. Body mass index and endometriosis have been observed to be inversely related; however, this relationship may only be a correlation rather than a causation. Obesity may play a role in the inflammation and cell proliferation associated with endometriosis through the complex signaling pathways of adipokines. A literature review was done on endometriosis and obesity to gain insight and synthesize knowledge about opportunities to improve endometriosis care, …

Age-Independent Anti-Angiogenic Therapy For Choroidal Neovascularization By Targeting Secretogranin Iii, Chengchi Huang, Hong Tian, Wei Li

Faculty, Staff and Students Publications

Recent studies reported that anti-angiogenic drugs targeting vascular endothelial growth factor (VEGF) alleviate choroidal neovascularization (CNV) in young but not aged animals. We recently developed a disease-targeted anti-angiogenic therapy against secretogranin III (Scg3), which selectively binds to diseased but not healthy vessels in young mice. Herein, using a unique in vivo ligand binding assay, we predicted and confirmed that Scg3 selectively binds CNV vessels in both young and aged mice. In contrast, VEGF with minimal increased binding to CNV vessels exhibited an age-dependent decline in binding to both CNV and healthy vessels with negligible binding in aged mice. Based on …

Faculty, Staff and Students Publications

Objectives: Candida species are one of the most common causes of ICU-onset bloodstream infection (BSI). Yet, there is no robust guidance on when to initiate empiric antifungals for ICU patients suspected of BSI. We compared patients with ICU-onset candidemia vs. ICU-onset bacteremia to determine which patients may benefit from empiric antifungals.

Design: We compared characteristics between patients with bacteremia vs. candidemia at time of culture. We determined risk factors for death and constructed a multivariable regression to determine if candidemia is an independent risk factor for death.

Setting/patients: We included ICU patients from a hospital system in Houston, Texas (n …

Faculty, Staff and Students Publications

Objective: Children with neurogenic bladder (NGB) are at increased risk for urinary tract infections (UTIs), but there is a lack of guidelines to assist clinicians in diagnosing and treating these children. Our objective was to describe the presentation and treatment of provider diagnosed UTIs in children with NGB compared to children with vesicoureteral reflux (VUR) and to assess the proportion of children with NGB who met a consortium definition of UTI.

Study design: We included children < 18 years old with either VUR or NGB who were diagnosed in the emergency department with a febrile UTI in our multicenter retrospective cohort study. We extracted and compared UTI symptoms and urinalysis results specific to children with NGB to children with VUR. We measured the proportion of UTI diagnoses concordant with the Urologic Management to Preserve Initial Renal Function (UMPIRE) consensus definition of UTI, defined as ≥ 100,000 CFU/mL of 1 or 2 organisms, pyuria, and ≥ two symptoms of UTI.

Results: The most common symptom among all children in the cohort was vomiting (38.8 %). Of the 215 children with NGB, 41.3 % met …

Artificial Intelligence In Allergy And Immunology: Recent Developments, Implementation Challenges, And The Road Toward Clinical Impact, Merlijn Van Breugel, Matt Greenhawt, Ibon Eguiluz-Gracia, Maria Jose Torres Jaén, Aikaterini Anagnostou, Gerard H Koppelman

Faculty, Staff and Students Publications

Artificial intelligence (AI) is increasingly recognized for its capacity to transform medicine. While publications applying AI in allergy and immunology have increased in number, clinical implementation substantially lags behind other specialties. By mid-2024, over 1,000 US Food and Drug Administration-approved AI-enabled medical devices existed, but none specifically addressed allergy and immunology. This gap partly reflects the field's limited reliance on imaging, which facilitated early AI breakthroughs in radiology and pathology. This narrative review examines recent AI developments, including large language models and AI agents, evaluating their applicability to allergy and immunology practice. We analyze current and potential applications, emphasizing those …

Induction Of Yin Yang 1 (Yy1) Overexpression In Mature Adipocytes Promotes Dysfunctional Adipose Tissue And Systemic Insulin Resistance In Mice, Line Pedersen, Christy M Gliniak, Thomas Myhre Dale, Qingzhang Zhu, Chao Li, Jan-Bernd Funcke, Clair Crewe, Jiahui Luo, Lauren Palluth, Yi Zhu, Philipp E Scherer

Faculty, Staff and Students Publications

The ubiquitous transcription factor Ying Yang 1 (YY1) plays a fundamental role in multiple biological processes and is believed to regulate up to 10 % of all human genes. In thermogenic brown adipose tissue, YY1 has been linked to controlling mitochondrial gene expression and regulating cellular oxidative respiration, protecting against diet-induced obesity and alterations in energy balance. The role of YY1 in non-thermogenic, white adipose tissue, on the other hand, remains largely unknown. Here, we show that adipocyte-specific induction of YY1 promotes dysfunctional adipose tissue and systemic insulin resistance in mice. Long-term YY1 induction in mature adipocytes leads to reduced …

Children’s Nutrition Research Center Staff Publications

Objective: Pair-feeding is a study design element where one group's food intake is provided to another group to assess whether a treatment effect is independent of food intake. Investigators often assume equivalent food intake across experimental conditions and exclude it from the statistical analysis. However, the impact of this practice on type I error (T1Er) rates has not been quantified.

Methods: We conducted a Monte Carlo simulation in which animals were assigned baseline weights and food intakes, then randomized to non-pair-fed or pair-fed groups. Daily food intake for both groups was initially drawn from the baseline food intake distribution. For …
