BACKGROUND AND AIMS: Paucity of intrahepatic bile ducts (BDs) is caused by various etiologies and often leads to cholestatic liver disease. For example, in patients with Alagille syndrome (ALGS), which is a genetic disease primarily caused by mutations in jagged 1 ( JAG1) , BD paucity often results in severe cholestasis and liver damage. However, no mechanism-based therapy exists to restore the biliary system in ALGS or other diseases associated with BD paucity. Based on previous genetic observations, we investigated whether postnatal knockdown of the glycosyltransferase gene protein O -glucosyltransferase 1 ( Poglut1) can improve the ALGS liver phenotypes in …

METHODS: We analysed stool samples from a surveillance sample within a birth cohort in a rural district in tropical Ecuador. The cohort was followed to 8 years of age for the presence of G. lamblia in stools by quantitative PCR and A and B assemblages by Taqman assay or Sanger sequencing. We explored risk factors associated with infection using generalized estimating equations applied to longitudinal binary …

Does Chronic Obstructive Pulmonary Disease Originate From Different Cell Types?, Yohannes Tesfaigzi, Jeffrey L Curtis, Irina Petrache, Francesca Polverino, Farrah Kheradmand, Ian M Adcock, Stephen I Rennard

Faculty, Staff and Students Publications

The onset of chronic obstructive pulmonary disease (COPD) is heterogeneous, and current approaches to define distinct disease phenotypes are lacking. In addition to clinical methodologies, subtyping COPD has also been challenged by the reliance on human lung samples from late-stage diseases. Different COPD phenotypes may be initiated from the susceptibility of different cell types to cigarette smoke, environmental pollution, and infections at early stages that ultimately converge at later stages in airway remodeling and destruction of the alveoli when the disease is diagnosed. This perspective provides discussion points on how studies to date define different cell types of the lung …

Faculty, Staff and Students Publications

Carcinosarcomas of the biliary tract are an extremely rare type of malignancy and may be low on a differential when presenting as multiple metastatic masses. In this case report, we report a case of a female who presented with an aggressive late-stage disease whose initial workup did not indicate a malignant process. Further complicating her care, biopsy samples taken from extra-hepatic masses were culture-positive for Lactobacillus rhamnosu. Given the late stage of the patient’s disease, hospice care was initiated. The patient passed away four months after the initial presentation.

Preterm Pigs Fed Donor Human Milk Have Greater Liver Β-Carotene Concentrations Than Pigs Fed Infant Formula, Nancy E Moran, Joshua Wade, Rachel Stroh, Barbara Stoll, Gregory Guthrie, Amy B Hair, Douglas G Burrin

Faculty, Staff and Students Publications

BACKGROUND: Milk carotenoids may support preterm infant health and neurodevelopment. Infants fed human milk often have higher blood and tissue carotenoid concentrations than infants fed carotenoid-containing infant formula (IF). Donor human milk (DHM) is a supplement to mother's own milk, used to support preterm infant nutrition.

OBJECTIVES: We tested whether tissue and plasma β-carotene concentrations would be higher in preterm pigs fed pasteurized DHM versus premature IF.

METHODS: This is a secondary analysis of samples collected from a study of the effects of enteral diet composition on necrotizing enterocolitis incidence. Preterm pigs received partial enteral feeding of either DHM (n …

Faculty, Staff and Students Publications

BACKGROUND: CDKL5 Deficiency Disorder (CDD) is a severe X-linked developmental and epileptic encephalopathy. Existing developmental outcome measures have floor effects and cannot capture incremental changes in symptoms. We modified the caregiver portion of a CDD clinical severity assessment (CCSA) and assessed content and response-process validity.

METHODS: We conducted cognitive interviews with 15 parent caregivers of 1-39-year-old children with CDD. Caregivers discussed their understanding and concerns regarding appropriateness of both questions and answer options. Item wording and questionnaire structure were adjusted iteratively to ensure questions were understood as intended.

RESULTS: The CCSA was refined during three rounds of cognitive interviews into …

The Impact Of Vaccine-Linked Chemotherapy On Liver Health In A Mouse Model Of Chronic Trypanosoma Cruzi Infection, Duc Minh Nguyen, Cristina Poveda, Jeroen Pollet, Fabian Gusovsky, Maria Elena Bottazzi, Peter J Hotez, Kathryn Marie Jones

Faculty, Staff and Students Publications

BACKGROUND: Chagas disease, chronic infection with Trypanosoma cruzi, mainly manifests as cardiac disease. However, the liver is important for both controlling parasite burdens and metabolizing drugs. Notably, high doses of anti-parasitic drug benznidazole (BNZ) causes liver damage. We previously showed that combining low dose BNZ with a prototype therapeutic vaccine is a dose sparing strategy that effectively reduced T. cruzi induced cardiac damage. However, the impact of this treatment on liver health is unknown. Therefore, we evaluated several markers of liver health after treatment with low dose BNZ plus the vaccine therapy in comparison to a curative dose of BNZ. …

Pediatric Microsurgery And Free-Tissue Transfer, Heather R Burns, Anna J Skochdopole, Richardo Alfaro Zeledon, William C Pederson

Faculty, Staff and Students Publications

Advancements in microsurgery, along with increased microsurgical experience in pediatric patients, have made free-tissue transfer a reliable modality for pediatric bone and soft tissue reconstruction today. Free-tissue transfer is most commonly used in children for the coverage of large or complex defects resulting from traumatic, oncologic, or congenital etiologies. While flap success and complication rates between pediatric and adult populations are similar, special considerations must be taken into account within the pediatric population. In this article, we will describe common indications, technical nuances, and clinical considerations for the management of the pediatric free-tissue transfer patient.

Diagnosing heart failure is often difficult due to the non-specific nature of symptoms, which can be caused by a range of medical conditions. Natriuretic peptides (NPs) have been recognized as important biomarkers for diagnosing heart failure. This document from the Heart Failure Association examines the practical uses of N-terminal pro-B-type natriuretic peptide (NT-proBNP) in various clinical scenarios. The concentrations of NT-proBNP vary according to the patient profile and the clinical scenario, therefore values should be interpreted with caution to ensure appropriate diagnosis. Validated cut-points are provided to rule in or rule out acute heart failure in the emergency department and …

Lymphoma is one of the most common cancers in adolescents and young adults, but historically, this population has had lower clinical trial enrollment and improvements in overall survival as compared to other age populations. There are multiple challenges that are unique to this population that have affected drug development and clinical trial enrollment. Our panel of experts have identified barriers, and in this review, we discuss current methods to address these barriers as well as potential solutions moving forward.

Mature B-Cell Lymphomas In Adolescents And Young Adults, Nader Kim El-Mallawany, Lisa Giulino-Roth, John M Burke, Michelle Hermiston, Carl E Allen

Faculty, Staff and Students Publications

Pediatric non-Hodgkin lymphoma includes over 30 histologies (many with subtypes), with approximately 800 cases per year in the US, compared to >60,000 cases of adult NHL annually. Improvements in survival in pediatric and adolescent mature B cell NHL over the past 5 decades align with the overall success of the cooperative trial model with dramatic improvements in outcomes through dose escalation of chemotherapy and, more recently, targeted therapy with rituximab. Pediatric dose-intense strategies carry risks of long-term consequences, but treatment failure is nearly universally fatal. By comparison, adult mature B cell lymphoma is typically less aggressive and treated with less …

Intratumoral Nanofluidic System Enhanced Tumor Biodistribution Of Pd-L1 Antibody In Triple-Negative Breast Cancer, Hsuan-Chen Liu, Simone Capuani, Andrew A Badachhape, Nicola Di Trani, Daniel Davila Gonzalez, Robin S Vander Pol, Dixita I Viswanath, Shani Saunders, Nathanael Hernandez, Ketan B Ghaghada, Shu-Hsia Chen, Elizabeth Nance, Ananth V Annapragada, Corrine Ying Xuan Chua, Alessandro Grattoni

Faculty, Staff and Students Publications

Immune checkpoint inhibitors (ICI), pembrolizumab and atezolizumab, were recently approved for treatment-refractory triple-negative breast cancer (TNBC), where those with Programmed death-ligand 1 (PD-L1) positive early-stage disease had improved responses. ICIs are administered systemically in the clinic, however, reaching effective therapeutic dosing is challenging due to severe off-tumor toxicities. As such, intratumoral (IT) injection is increasingly investigated as an alternative delivery approach. However, repeated administration, which sometimes is invasive, is required due to rapid drug clearance from the tumor caused by increased interstitial fluid pressure. To minimize off-target drug biodistribution, we developed the nanofluidic drug-eluting seed (NDES) platform for sustained intratumoral …

Safely expanding indications for cellular therapies has been challenging given a lack of highly cancer-specific surface markers. Here we explore the hypothesis that tumor cells express cancer-specific surface protein conformations that are invisible to standard target discovery pipelines evaluating gene or protein expression, and these conformations can be identified and immunotherapeutically targeted. We term this strategy integrating cross-linking mass spectrometry with glycoprotein surface capture ‘structural surfaceomics’. As a proof of principle, we apply this technology to acute myeloid leukemia (AML), a hematologic malignancy with dismal outcomes and no known optimal immunotherapy target. We identify the activated conformation of integrin β2 …
