Rare genetic diseases (RDs) with primary neuropsychiatric symptoms pose unique challenges for diagnosis and management. While the majority of these RDs have neuropsychiatric symptoms that are secondary to the RD, a subset presents with primary neuropsychiatric symptoms directly linked to their underlying pathophysiology. This subset has significant unmet medical need with delayed diagnoses leading to prolonged delays in treatment optimization and the trialing of medications that fail to target the underlying pathophysiology. This comprehensive review identifies 108 RDs with central neuropsychiatric symptoms that have a 7.7-year average diagnostic delay. Optimal management strategies for these RDs typically includes non-psychotropic medications, dietary …

Background & aims: Metastatic cancers arise from a decades-long succession of increasingly virulent precursor lesions, each of which represents prospective targets for therapeutic intervention. This evolutionary process has been particularly vivid in esophageal adenocarcinoma (EAC), as this cancer and associated precursor lesions, including Barrett's esophagus (BE), low-grade dysplasia (LGD), and high-grade dysplasia (HGD), coexist in an accessible, 2-dimensional pattern in esophageal mucosa. Given the durability of these precursor lesions, it is likely that they, like EAC, rely on stem cells for their regenerative growth. To assess the role of stem cells in the evolution of EAC, we apply technology that …

In the realm of medical procedures for urinary obstructions, a distinct division of roles is evident: the vast majority of percutaneous nephrostomies (PCNs) are the domain of Interventional Radiology (IR), while the placement of double J stents (JJ stents) falls squarely under Urology. This division, however, is not without its complexities. When confronted with a patient suffering from a urinary obstruction, the decision-making process can become intricate. The underlying cause often fuels the debate: should IR intervene with a PCN, or should Urology place a JJ stent? Such decisions have profound implications for the individual patient.In this comprehensive review, we …

Use Of Granulocyte-Colony Stimulating Factor For Beta-Lactam Induced Neutropenia In Children With Bacterial Meningitis, Cheng Yu Yen, Sheldon L Kaplan, Debra L Palazzi, Grant Stimes

Faculty, Staff and Students Publications

Drug induced neutropenia is an uncommon but potentially serious side effect in children receiving prolonged β-lactam antibiotic therapy. Management of β-lactam induced neutropenia in children remains challenging and often requires antibiotic therapy interruption or modification. There are limited data in pediatric patients about use of granulocyte-colony stimulating factor (G-CSF) for the treatment of drug induced neutropenia. We report the use of G-CSF for β-lactam induced neutropenia in four pediatric patients between the ages of 3 months and 18 years with bacterial meningitis in this case series.

Metabolic reprogramming is a key focus of targeted therapies in acute myeloid leukemia (AML). The mitochondrial sirtuin SIRT5 removes succinyl groups from specific lysines and impacts cell metabolism, but its role in AML tumorigenesis has not been extensively explored. A recent study highlighted that SIRT5 regulates AML cell activity by modulating glutamine metabolism, but its molecular targets in AML remain unclear. This study aims to identify the substrates of SIRT5 in AML. It was found that a total of 83 proteins with 121 lysine (K) residues showed increased succinylation after SIRT5 knockdown, as determined by succinylome analysis of MOLM-13 cells. …

Mutations in protein O-glucosyltransferase 1 (POGLUT1) cause a recessive limb-girdle muscular dystrophy (LGMDR21) with reduced satellite cell number and NOTCH1 signaling in adult patient muscles and impaired myogenic capacity of patient-derived muscle progenitors. However, the in vivo roles of POGLUT1 in the development, function, and maintenance of satellite cells are not well understood. Here, we show that conditional deletion of mouse Poglut1 in myogenic progenitors leads to early lethality, postnatal muscle growth defects, reduced Pax7 expression, abnormality in muscle extracellular matrix, and impaired muscle repair. Poglut1-deficient muscle progenitors exhibit reduced proliferation, enhanced differentiation, and accelerated fusion into myofibers. Inducible loss …

The nervous system has a pivotal role in cancer biology, and pathological investigations have linked intratumoural nerve density to metastasis1. However, the precise impact of cancer-associated neurons and the communication channels at the nerve–cancer interface remain poorly understood. Previous cancer denervation models in rodents and humans have highlighted robust cancer dependency on nerves, but the underlying mechanisms that drive nerve-mediated cancer aggressivity remain unknown2,3. Here we show that cancer-associated neurons enhance cancer metabolic plasticity by transferring mitochondria to cancer cells. Breast cancer denervation and nerve–cancer coculture models confirmed that neurons significantly improve tumour energetics. …

Mx1-Labeled Pulp Progenitor Cells Are The Main Contributors Of Odontoblast And Dentin Regeneration In Murine Molars, Dongwook Yang, Youngjae Jeong, Laura Ortinau, Jea Giezl Solidum, Dongsu Park

Faculty, Staff and Students Publications

Regeneration of dentin and odontoblasts from dental pulp progenitor cells is essential for the maintenance of permanent tooth. However, the in vivo identity of endogenous pulp progenitor cells and how they contribute to reparative dentinogenesis remain elusive. Here we show that comparative single-cell analysis of pulp cells before and after molar eruption reveal that endogenous pulp progenitor cells are enriched in coronal papilla-like cells with Mx1-Cre and Cxcl12–GFP expression. Further, lineage tracing and fluorescence-activated cell sorting analysis indicated that Mx1-labeled (Mx1+) pulp cells include long-term repopulating progenitor cells with higher expression of stem cell markers. Notably, …

Multivariate Optical Imaging Of The Oxygen-Metabolism Axis, Jesse D. Ivers

Graduate Theses and Dissertations

Metabolic reprogramming is a characteristic hallmark of multiple pathologies and promotes disease progression, survival, and severity. Current methods to investigate metabolic reprogramming, however, require reductions of dimensionality both because of instrumentation limitations and analysis tools. This work aims to define a blueprint for high dimensional study of the oxygen metabolism axis to enable more sensitive study metabolic reprogramming. We hypothesized (1) multivariate imaging of metabolic and oxygenation metrics in ex vivo tissue sections would elucidate differences in resistant and sensitive head and neck squamous cell carcinoma (HNSCC) xenografts that traditional uni-variate methods miss and (2) an engineered hyperspectral darkfield microscopy …

Faculty, Staff and Students Publications

Background/Objectives: This study aimed to identify the risk factors for respiratory failure in patients with intracerebral hemorrhage (ICH) accompanied by intraventricular hemorrhage (IVH) extension.

Methods: We retrospectively included 208 patients with ICH accompanied by IVH extension. Respiratory failure was defined as carbon dioxide levels > 45 mmHg with a pH < 7.35 in arterial blood gas analysis (ABGA) or the application of a ventilator due to respiratory dysfunction. We measured the severity of IVH extension using the Graeb scale, and ICH volume was assessed for each patient.

Results: Of the 208 included patients, 83 had respiratory failure. There were no significant differences in age, sex ratio, or Graeb scale score between patients with and without respiratory failure (p > 0.05). However, ICH volume was significantly larger in patients with respiratory failure (42.0 ± 42.5 mL) than …
