2020-Current year OA Pubs

We examined cognitive changes associated with several neuropathologic entities, alone and in combination. We studied 808 participants from the National Alzheimer's Coordinating Center to assess associations between neuropathologic diagnoses (from autopsy) and neuropsychologic test scores (trajectories over time for 5 domains: overall cognition, episodic memory, attention, language, executive function). Neuropathologies included: Alzheimer disease neuropathologic change (ADNC), Lewy body disease (LBD), vascular brain injury (VBI), and limbic-predominant age-related TDP43 encephalopathy neuropathologic change (LATE-NC). Using linear mixed-effects models, we examined trajectories of cognitive decline for ADNC alone compared to ADNC plus LBD, VBI, or LATE-NC. We also examined differences between observed trajectories …

Are We Winning At Twinning? Persistent Cni Use In Identical Kidney Transplants., Nicholas S. Herrera, Shivani Wadnerkar, Diane M. Cibrik

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Calcineurin inhibitors (CNIs) revolutionized kidney transplantation by reducing acute rejection rates. Identical twin kidney transplantation is the only setting in which the allograft is immunologically indistinguishable from self, yet CNI use persists. We characterized CNI utilization across end-stage kidney disease etiologies and examined whether CNI exposure was associated with reduced rejection or improved death-censored graft survival (DCGS).

METHODS: We performed a retrospective cohort study using scientific registry of transplant recipients data (January 2000-August 2025). Among 255 adult identical twin kidney transplant recipients, discharge regimens were categorized by CNI use; Firth penalized Cox regression was the primary method for 10-year …

Detection of Alzheimer's disease (AD) before the development of clinical symptoms is critical for enabling the use of new treatments. Circular RNAs (circRNAs) are highly stable non-coding RNAs enriched in the brain that can cross the blood-brain barrier. Here, analyzing blood data from 1,221 individuals with AD and healthy individuals, we identified 34 circRNAs associated with AD status. A predictive model including these 34 circRNAs was comparable to plasma phosphorylated Tau-217 (pTau217) in classifying AD based on biomarker-confirmed (amyloid-β and Tau) status and replicated in independent samples from the Knight-Alzheimer Disease Research Center (n = 551: 76 AD, 475 cognitively …

2020-Current year OA Pubs

Incidence of early-onset cancer is rising globally in recent generations, which underscores the need to elucidate the influence of emerging generational risk factors. Systemic and organ-specific aging reflects the cumulative impact of exposures and may provide an integrative and complementary approach to understand early-onset cancer risk. Here among 154,169 young adults from the United Kingdom Biobank, systemic aging measured by PhenoAge increased across birth cohorts, with 23% s.d. increase for those born 1965-1974 versus 1950-1954, and was associated with early-onset solid cancer risk (hazard ratio (HR)

Dupilumab Versus Placebo In Adults And Adolescents With Eosinophilic Gastritis (Degas): A Double-Blind, Placebo-Controlled, Phase 2, Multicentre, Randomised Controlled Trial, Tetsuo Shoda, Regina Yearout, Seema S Aceves, Nicoleta C Arva, John A Besse, Julie M Caldwell, Mirna Chehade, Amaziah Coleman, Margaret H Collins, Sara Anvari, Gary W Falk, Sandeep K Gupta, Girish Hiremath, David A Katzka, Paneez Khoury, John Leung, Calies Menard-Katcher, Paul Menard-Katcher, Kathryn A Peterson, Maria A Pletneva, Amanda K Rudman Spergel, Jonathan M Spergel, Tatyana Vaysman, Joshua B Wechsler, Benjamin L Wright, Guang-Yu Yang, Xue Zhang, Meijian Zhou, Ashish Bansal, Bram P Raphael, Amr Radwan, Jennifer Maloney, Antonio Martin, Yamo Deniz, Glenn T Furuta, Lisa J Martin, Marc E Rothenberg

Children’s Nutrition Research Center Staff Publications

Background: Preeclampsia is the most common complication of pregnancy, significantly affecting maternal and fetal health, and is characterized by placental and systemic endotheliopathy. Patients with preeclampsia have elevated levels of VWF (von Willebrand Factor), which is associated with poor clinical outcomes. However, whether VWF serves as a marker for endotheliopathy or contributes to the pathogenesis of preeclampsia remains poorly understood.

Methods: We investigated the role of hyperadhesive VWF in the development of preeclampsia by studying patients, evaluating mouse models, and performing in vitro experiments.

Results: We show that patients develop VWF- and fibrin-rich thrombosis in the placenta and have significantly …

Select Plasma Oxylipins As Potential Biomarkers Of Effective Indomethacin Treatment Response In Preterm Infants With Patent Ductus Arteriosus., Khanh C K Nguyen, Cindy H T Yeung, Allison Scott, Thomas J. Velenosi, Tamorah Lewis

Manuscripts, Articles, Book Chapters and Other Papers

OBJECTIVES: Patent ductus arteriosus (PDA) is one of the most common heart conditions in preterm infants, and indomethacin treatment is used for PDA closure. However, its efficacy varies among patients. This pilot study aimed to identify novel metabolic biomarkers to predict effective indomethacin response in infants with PDA.

METHODS: Preterm infants with PDA <  34 weeks gestational age were recruited and treated with indomethacin. Plasma and urine samples were collected before and 2-7 days after initial treatment. Longitudinal targeted oxylipin and untargeted metabolomics analysis were performed on plasma and urine samples.

RESULTS: Among 17 infants, 12 were responders and 5 non-responders to indomethacin treatment. Before the treatment, four plasma oxylipins: 12,13-DiHOME, 9,10-DiHOME, 15,16-DiHODE, and 9,10-DiHODE were significantly higher in responders compared to non-responders (P <  0.05). Following treatment, these oxylipins decreased in responders but remained stable in non-responders. Urinary 12,13-DiHOME showed an opposite trend, with lower baseline concentrations in the responders.

CONCLUSIONS: Pre-treatment plasma levels of four oxylipins were associated with effective PDA response to …

Extracellular matrix (ECM) dysregulation plays a significant role in the development of intervertebral disc disease (IVDD). The ECM around the chondrocytes in the nucleus pulposus (NP) is unique in that it contains ColVI. While linked to chondrocyte proliferation in cartilage, ColVI's specific role in IVD degeneration is less clear. Our aim was to determine the expression of ColVI in NP cells from degenerative IVDs, along with the effects of soluble ColVI on NP cells. Thus, we compared the expression levels of ColVI in human degenerated IVD samples, along with the effect of soluble ColVI on primary human NP cells. A …

Faculty, Staff and Students Publications

Since emerging in late 2019, SARS-CoV-2 has caused over 7 million deaths globally and remains a public health concern. Understanding SARS-CoV-2 pathogenesis is vital, especially as factors like environmental exposures are still poorly understood. Polycyclic aromatic hydrocarbons (PAHs), like benzo[a]pyrene (BP), found in pollutants like cigarette smoke, diesel exhaust, and charcoal-broiled steaks, are known to injure the lungs. We aimed to evaluate if BP exacerbates SARS-CoV-2 pathogenesis in a mouse model of disease. One day following intranasal administration of BP (20 mg/kg) or vehicle control, we infected male and female K18-hACE2 mice with ancestral SARS-CoV-2 and assessed lung viral load, …

Effects Of Non-Surgical Periodontal Therapy On Dental Plaque Microbiome

Faculty, Staff and Student Publications

Periodontitis, a chronic inflammatory disease affecting approximately 40% of U.S. adults aged 30 years and older, is characterized by dysbiosis of the dental plaque microbiome. However, although scaling and root planing (SRP) is the cornerstone of periodontal treatment, its effects on the taxonomic composition and functional potential of the dental plaque microbiome remain incompletely understood. In this study, we used whole-metagenome shotgun sequencing to characterize taxonomic composition and functional potential in dental plaque microbiomes collected from 39 patients with Stage II or III generalized periodontitis before and 3–4 months after SRP. Consistent with clinical improvement, periodontal therapy significantly reduced probing …

Female germ cells must preserve the integrity of their genome and generate genetic diversity via meiotic recombination. This challenging process is error prone. Highly conserved checkpoint pathways detect errors in recombination and DNA damage, inducing the death of defective oocytes. Nuclear Envelope Membrane Protein (NEMP) homologs are highly conserved proteins critical for fertility in flies, worms, fish and mice. They localize to the inner nuclear envelope where they provide mechanical support. However, why NEMP homologs are specifically required for fertility is still unclear. Using both Drosophila and mouse models, we establish that loss of NEMP homologs leads to activation of …
