Faculty, Staff and Students Publications

Objective and methods: Brown adipose tissue (BAT) comprises a heterogeneous population of adipocytes and non-adipocyte cell types. To characterize these cellular subpopulations and their adaptation to cold, we performed single-nucleus mRNA-sequencing (snRNA-seq) on interscapular BAT from mice maintained at room temperature or exposed to acute (24h) or chronic (10 days) cold (6 °C). To investigate the role of the de novo lipogenesis (DNL)-regulating transcription factor carbohydrate response element-binding protein (ChREBP), we analyzed control and brown adipocyte-specific ChREBP knockout mice.

Results: We identified different cell populations, including seven brown adipocyte subtypes with distinct metabolic profiles. One of them highly expressed ChREBP …

From Pachymeningitis Hemorrhagica To Abusive Head Trauma: A Journey Through The Centuries, Oliver Berthold, Flora Blangis, Christopher Spencer Greeley

Faculty, Staff and Students Publications

The development of medical knowledge follows specific principles. These also apply to abusive head trauma. The seminal literature from the early 20th century is based on earlier research from Europe, which is fundamental to understand the evolution of understanding and nomenclature of abusive head trauma. A review of original medical literature on intracranial injuries in children, published in German, English, and French, was conducted using PubMed and Google Scholar for articles before 1950. The primary search focused on subdural hemorrhages and pachymeningitis in children, followed by a snowball search of references. Full texts of available manuscripts were reviewed. Primary literature …

Alzheimer's Disease (AD) is a global health issue, affecting over 6 million people in the United States, with that number expected to increase as the population ages. As a neurodegenerative disorder that affects memory and cognitive functions, it is well established that AD is associated with cardiovascular risk factors beyond only cerebral decline. In this study, we measured hemodynamic parameters related to cardiovascular and cerebrovascular function in 5xFAD mice with AD and their littermates. Specifically, we measured cardiovascular pulse wave velocity parameters, a marker of arterial stiffness and cardiovascular risk, and cerebrovascular pulse wave velocity, a novel technique to measure …

The present review is an evaluation of the antifungal activity of metal-based nanoparticles, including silver (Ag), copper (Cu), zinc oxide (ZnO), titanium dioxide (TiO₂), and selenium (Se) in relation to the three predominant pathogenic fungi. It also talks about their mode of action, relative efficacy, toxicity and their possible future clinical …

Lyme Disease Presenting As A Dermal Hypersensitivity Reaction, William T. Snider, Ian Depew, Rebecca Hicks, Shane Cook

Marshall Journal of Medicine

Background:

Lyme disease is a well-recognized illness commonly associated with skin manifestations such as erythema migrans. However, atypical presentations can complicate diagnosis, particularly when they deviate from classic clinical and histological findings.

Methods:

We report a potential case of Lyme disease presenting as a dermal hypersensitivity reaction (DHR), with clinical findings resembling urticaria rather than urticarial vasculitis. Skin biopsy findings were reviewed, and Lyme serology testing was performed.

Results:

The biopsy did not demonstrate the characteristic superficial perivascular lymphocytic infiltrate typically seen with erythema migrans. The patient's history included prior tick exposures, but while Lyme IgM was positive, the Lyme …

Mirm In An Adolescent Male: A Diagnostic Challenge And Review Of The Literature, Emily Saurborn, Savannah Carty, Shane Cook, Lauren Tufts

Marshall Journal of Medicine

Mycoplasma-Induced Rash and Mucositis (MIRM) is a subset of Reactive Infectious Mucocutaneous Eruption (RIME), most commonly associated with Mycoplasma pneumoniae. MIRM commonly presents with significant mucositis and mild or absent cutaneous involvement. MIRM exists on a spectrum with Stevens-Johnson Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN). Due to the significant clinical overlap, early diagnosis of MIRM can be challenging. We report a case of a 19-year-old male who presented with a two-day history of worsening throat pain and decreased oral intake after initiating Augmentin for treatment of community acquired pneumonia. During hospitalization, he developed progressive ocular, oral and genital …

Rectal Fidaxomicin As Salvage Therapy In Fulminant Clostridioides Difficile Infection After Total Colectomy: A Case Report, Akankcha Alok, Mohamed Ismail, Stephanie Pino Fabara, Mohammed Al Said, Vidya Sagar Kollu

HCA Healthcare Journal of Medicine

Introduction

Clostridioides difficile infection (CDI) is a significant cause of antibiotic-associated diarrhea and colitis, ranging from mild to severe and potentially life-threatening conditions, like fulminant colitis with toxic megacolon and bowel perforation. The 2021 guidelines from the Infectious Diseases Society of America (IDSA) and Society for Healthcare Epidemiology of America (SHEA) recommend vancomycin and metronidazole for fulminant CDI (FCDI), with consideration of rectal vancomycin for cases with ileus. Fidaxomicin, though preferred for initial and recurrent CDI treatment, is not the first line for FCDI due to limited evidence. Fidaxomicin has a narrow spectrum of activity only targeting C difficile and …

Perceived Benefits And Side Effect Of High-Fiber, High-Protein Meal Replacements In Weight Loss Programs, Esti Nurwanti, Harry Fl Muhammad, Naufal M. Nurdin

Indonesian Journal of Public Health Nutrition (IJPHN)

Obesity is a major risk factor for chronic diseases and early mortality. Although dietary counseling is essential in managing obesity, maintaining a calorie deficit and preventing weight regain remain difficult. Functional foods like high-protein, high-fiber meal replacements may enhance adherence and support weight loss. This randomized controlled trial evaluated the subjective outcomes of a weight loss program incorporating a protein- and fiber-enriched meal replacement among 73 overweight women aged 20–30 years. Participants were randomized to an intervention group (n=38), receiving dietary counseling plus one daily meal replacement, or a control group (n=35), receiving counseling alone. Both groups followed an 8-week …

The Effectiveness Of Screencast Corrective Feedback On L2 English Academic Writing, Ming Cheng

Electronic Theses and Dissertations Archive

While research indicates that written corrective feedback (WCF) can promote learning of language and writing skills (Ferris, 2004; Bitchener, 2008), both students and teachers report persistent limitations. Students often find written comments difficult to interpret, while teachers consider them time-consuming to provide. Screencast corrective feedback (SCF) offers an alternative by utilizing screen recording technology to deliver audiovisual cues and personalized explanations that can reduce ambiguity and foster rapport (Harper et al., 2012). However, existing studies on SCF have largely emphasized learner perceptions rather than its measurable impact on language development (Cheng & Li, 2020). This dissertation investigates the comparative effectiveness …

Division of Cardiology Faculty Papers

BACKGROUND: Calciphylaxis is a rare, life-threatening vasculopathic syndrome most commonly seen in end-stage renal disease (ESRD) and associated with high mortality. Vitamin K antagonists complicate management in patients with mechanical valves by potentially exacerbating vascular calcification while remaining essential for thromboprophylaxis.

CASE PRESENTATION: A 50-year-old woman with ESRD on hemodialysis and a mechanical mitral valve on warfarin presented with severe abdominal pain and rapidly progressive necrotic ulcers. Despite broad-spectrum antibiotics and sodium thiosulfate, lesions worsened. Biopsies were nondiagnostic; however, the clinical phenotype was consistent with calciphylaxis. A multidisciplinary team transitioned anticoagulation from warfarin to subcutaneous unfractionated heparin (UFH) (333 U/kg …

Sexually transmitted infections, e.g., Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and Mycoplasma genitalium (MG), present with similar signs/symptoms and are often treated empirically due to delays in receiving diagnostic test results. This study evaluated the clinical performance of the Cobas Liat CT/NG/MG nucleic acid amplification test (NAAT) in detecting these pathogens in a point-of-care (POC) setting. This non-interventional, multicenter study recruited symptomatic/asymptomatic participants from 13 geographically diverse POC sites across the USA. Prospective clinician- and self-collected specimens (urine/vaginal swabs) were used to determine the sensitivity and specificity of the Cobas Liat CT/NG/MG test relative to the composite reference standard (CRS), …

Since the first approval of tisagenlecleucel in 2017, pediatric and young adult patients with relapsed/refractory B-cell acute lymphoblastic leukemia (B-ALL) may receive this CD19-directed chimeric antigen receptor T-cell therapy. We report real-world data from the Center for International Blood and Marrow Transplant Research (>2.5 years of follow-up). As of 4 May 2022, 768 patients with B-ALL had received tisagenlecleucel. Patients aged ≥18 and < 18 years of age (including those < 3 years) were treated during first relapse (26.6% and 26.7% [< 3 years, 44.8%], respectively) or primary refractory disease (12.4% and 12.1% [< 3 years, 15.5%], respectively) with 17.6% and 11.6% (< 3 years, 13.8%), respectively, having high disease burden (≥50% bone marrow [BM] blasts) and 20.2% and 20.2% (< 3 years, 13.8%), respectively, having low disease burden (>0 to < 5% BM blasts). Among patients with ≥12 months postinfusion follow-up (n = 578; median follow-up, 32.1 months), the best overall response of complete remission/complete remission with incomplete blood count recovery was 86.0%. The 12-month relapse-free survival (RFS) and overall survival (OS) were 61.8% and 79.4%, respectively, whereas the 24-month RFS and OS were 50.3% and 63.8%, respectively. Age (< 18 years) and disease burden (< 50% BM blasts) were associated with better outcomes. Previous inotuzumab therapy and KMT2A rearrangement were associated with worse outcomes. Older patients (≥18 years) experienced a higher rate of any-grade cytokine release syndrome (CRS) associated with higher disease burden before infusion. Any-grade CRS and neurotoxicity were lower in patients aged < 3 years. Extended follow-up continues to demonstrate high rates of RFS and favorable safety in this population.

Ameliorating Effect Of Haematococcus Pluvialis Powder On Lps-Induced Barrier Damage In Hok Cells, Xie Jinmei, Chen Cailian, Zhang Yong, Zheng Yunjian, Xie Xi

Food and Machinery

[Objective] To investigate the protective effect of Haematococcus pluvialis (H.pluvialis) powder on lipopolysaccharide (LPS)-induced oral epithelial damage. [Methods] The effects of different doses of H.pluvialis on the viability of human oral keratinocytes (HOKs) were assessed. In LPS-induced HOKs, changes in the tight junction-associated proteins ZO-1 and Occludin, mitochondrial morphology, reactive oxygen species (ROS), mitochondrial membrane potential (MMP), mitochondrial superoxide (MitoSOX), and mitochondrial permeability transition pore (MPTP) were evaluated. [Results] Compared with the LPS model group, high-dose H.pluvialis significantly upregulated the expression levels of Occludin and ZO-1 to 151.56% and 170.52%, respectively (P < 0.05), and promoted their membrane localization. In addition, H.pluvialis markedly improved LPS-induced excessive ROS and MitoSOX production, the reduction in MMP, and the increase in MPTP in HOKs. [Conclusion] H.pluvialis may alleviate LPS-induced barrier damage in HOKs by improving mitochondrial dysfunction and reducing oxidative stress, suggesting its potential as a functional food for oral mucosal barrier repair.
