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 …

The Changing Landscape Of Pediatric Cardiology Fellowship Applications: An Update On Objective Metrics And Current Evaluation Practices, William B Kyle, Tam T Doan, James C Wilkinson

Faculty, Staff and Students Publications

The application process for medical training fellowships has evolved significantly over the last decade. Important changes in access to quantitative data, the standardized application itself, and an unprecedented shift in the interview process have forced fellowship leaders to alter their evaluation process. This study aimed to assess each of those aspects of the pediatric cardiology fellowship application process. We review the application itself, focusing on the Experiences section of the Electronic Residency Application Service (ERAS) evaluation and the Pediatric Cardiology Fellowship Evaluation Form, which accompanies each letter of recommendation (LOR). In addition to these novel analyses, we present peer-reviewed literature …

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 …

The human metabolome reflects complex metabolic states affected by genetic and environmental factors. However, metabolites associated with type 2 diabetes (T2D) risk and their determinants remain insufficiently characterized. Here we integrated blood metabolomic, genomic and lifestyle data from up to 23,634 initially T2D-free participants from ten cohorts. Of 469 metabolites examined, 235 were associated with incident T2D during up to 26 years of follow-up, including 67 associations not previously reported across bile acid, lipid, carnitine, urea cycle and arginine/proline, glycine and histidine pathways. Further genetic analyses linked these metabolites to signaling pathways and clinical traits central to T2D pathophysiology, including …

Epstein–Barr virus (EBV) is an endemic herpesvirus implicated in autoimmunity, cancer and neurological disorders. Although primary infection is often subclinical, persistent EBV infection can drive immune dysregulation and long-term complications. Despite the ubiquity of infection, the determinants of EBV persistence following primary exposure remain poorly understood, although human genetic variation partially contributes to this phenotypic spectrum1–3. Here we demonstrate that existing whole genome sequencing (WGS) data of human populations can be used to quantify persistent EBV DNA. Using WGS and health record data from the UK Biobank (n = 490,560) and All of Us ( …

Key Points:

1. Cardiovascular-kidney-metabolic (CKM) is a global public health problem; however, its mediators remain poorly known, in part due to the lack of a reliable animal model.

2. A combination of high fat and adenine diet recapitulate some of the CKD and metabolic phenotypes of CKM.

3. This model also demonstrates myocardial fibrosis and peripheral artery disease with sex-based differences and can be leveraged to probe mechanisms of CKM.

Background: Cardiovascular-kidney-metabolic (CKM) syndrome is a public health problem in the United States and results in premature cardiovascular disease at a relatively preserved GFR. The molecular mediators of CKM are poorly understood, partly …

Type 2 diabetes (T2D) is a prevalent disease arising from complex molecular mechanisms. Here we leverage T2D genetic associations to identify causal molecular mechanisms in an ancestry-aware and tissue-aware manner. Using two-sample Mendelian randomization corroborated by colocalization across four global ancestries, we analyse 20,307 gene and 1,630 protein expression levels using blood-derived cis-quantitative trait loci (QTLs). We detect causal effects of genetically predicted levels of 335 genes and 46 proteins on T2D risk, with 16.4% and 50% replication in independent cohorts, respectively. Using gene expression cis-QTLs derived from seven T2D-relevant tissues, we identify causal links between the expression of 676 …

Technical Considerations And Contemporary Literature Review Of The Gore Thoracic Branch Endoprosthesis®, Bruno P Schmid, Lucas R Kanamori, Hannah V Oden-Brunson, Dora Babocs, Ying Huang, Jorge Miranda, Steven Maximus, Gustavo S Oderich

Faculty, Staff and Students Publications

Thoracic endovascular aortic repair (TEVAR) has become the preferred treatment for various thoracic aortic pathologies, including blunt thoracic aortic injury, aneurysms, and dissections. Involvement of Ishimaru Zone 2 occurs in up to 60% of TEVAR cases requiring extension across the distal aortic arch and left subclavian artery (LSA). Coverage of the LSA without revascularization increases the risk of complications such as upper extremity ischemia, stroke, and spinal cord injury. Therefore, the preservation of LSA perfusion during TEVAR is essential. Cervical debranching remains an effective alternative to preserve flow to the LSA, but it poses risks of bleeding, infection, and nerve …

Aging leads to a progressive decline in overall bladder function resulting in lower urinary tract symptoms and increased susceptibility to infections. However, tissue-specific mechanisms of aging, specifically the contributions of the urothelium, remain elusive. Here, we introduce mouse bladder epithelium-derived organoids (mBEDOs) as a scalable platform to model urothelial aging. mBEDOs from aged mice recapitulate key features of age-associated cellular reprogramming, including oxidative stress, senescence, and DNA damage. We demonstrate the utility of mBEDOs for modeling Uropathogenic Escherichia coli (UPEC) infection, generating assembloids between mBEDOs and macrophages to model epithelial-immune interactions, and genetic perturbation. Using the mBEDO platform, we also …

Cyclic Amp-Dependent Regulation Of Ryanodine Receptors In Healthy And Diseased Hearts, Mohit M Hulsurkar, Isabelle Ong, Joshua A Keefe, Issam H Abu-Taha, Dobromir Dobrev, Xander H T Wehrens

Faculty, Staff and Students Publications

Cyclic adenosine monophosphate (cAMP) is a critical second messenger in cardiomyocytes, regulating essential cellular functions. Upon G-protein-coupled receptor stimulation, adenylyl cyclase (AC) synthesizes cAMP, which phosphodiesterase (PDE) enzymes subsequently degrade. Recent studies challenge the traditional view of uniform cAMP signaling, revealing nanodomain-specific regulation within cardiomyocytes. This localized cAMP signaling modulates key Ca2+-handling proteins, including ryanodine receptor type-2 (RyR2), through channel-bound protein kinases and PDEs. Additionally, nucleoside-diphosphate kinases (NDPKs), particularly NDPK-C, contribute to cAMP synthesis and RyR2 regulation. Elevated NDPK-C levels in failing hearts correlate with increased cAMP levels, enhanced sarcoplasmic reticulum Ca2+ release, and cardiac arrhythmias. Furthermore, cAMP influences the …
