Arachnidism Leading To A Complicated Infection In A Middle Aged Female, Monica S. Drummond, Carol A. Medina, Madison A. Morgan, Alex J. Studebaker

Research Day

Arachnids are known to seek out dark, undisturbed areas, where they can be secluded. Although generally not known for their aggression towards humans, they are known to bite when prompted. Most bites occur unknowingly while cleaning a storage area, putting on clothing/shoes, doing yard-work, or even rolling over in bed. Often, the bite is painless. The severity of a patient’s reaction to the bite originates from the genus of arachnida, the amount of venom injected, and the individual’s sensitivity to it. Several types of arachnid venoms are known to be cytotoxic and hemolytic. While many initial bites are commonly painless, …

Estradiol Protects Against Pain-Facilitated Fentanyl Use Via Suppression Of Opioid-Evoked Dopamine Activity In Males, Jessica A Higginbotham, Julian G Abt, Rachel H Teich, Joanna J Dearman, Tania Lintz, Jose A Morón

2020-Current year OA Pubs

Pain relief is the most frequently reported motivation for opioid misuse, but it remains unclear how pain alters reward pathway function contributing to maladaptive opioid use and whether these neuroadaptations occur in a sex-specific manner. Here, we show that persistent inflammatory pain leads to augmented fentanyl self-administration in male, not female, rats. Wireless in vivo fiber photometry recordings and chemogenetic manipulations indicate that pain-facilitated fentanyl use is mediated by enhanced ventral tegmental area dopamine (VTA

A Honduran Prevalence Study On Soil-Transmitted Helminths Highlights Serological Antibodies To Tm-Wap49 As A Diagnostic Marker For Exposure To Human Trichuriasis, Neima Briggs, Leroy Versteeg, Rojelio Mejia, Jeroen Pollet, Maria Jose Villar, Bin Zhan, Graeme Segal, Stephanie Novak, Patricia Lenihan, Paul Musgrave, Viviana Ellis, Carol Florencia Coello, K Jagannadha Sastry, Joe Craft, Peter J Hotez, Maria Elena Bottazzi

Soil-transmitted helminth (STH) infections rank among the most prevalent communicable diseases of humans, yet detection of these parasites is mostly restricted to identifying active infection through fecal examinations. Currently, there are no commercial diagnostic tools to identify a prior whipworm or hookworm exposure, and the few serological assays for roundworm infection have not been well validated for crossreactivity or infections in humans. Such diagnostic restrictions limit the range of scientific and clinical questions that surround STH exposures and their implicated relationship to chronic diseases, such as autoimmunity, allergy, and cancer. The goal of this investigation was to evaluate the diagnostic …

Characterising Acute And Chronic Care Needs: Insights From The Global Burden Of Disease Study 2019, A. A. Asadi-Pooya

Department of Neurology Faculty Papers

Chronic care manages long-term, progressive conditions, while acute care addresses short-term conditions. Chronic conditions increasingly strain health systems, which are often unprepared for these demands. This study examines the burden of conditions requiring acute versus chronic care, including sequelae. Conditions and sequelae from the Global Burden of Diseases Study 2019 were classified into acute or chronic care categories. Data were analysed by age, sex, and socio-demographic index, presenting total numbers and contributions to burden metrics such as Disability-Adjusted Life Years (DALYs), Years Lived with Disability (YLD), and Years of Life Lost (YLL). Approximately 68% of DALYs were attributed to chronic …

The Thai Journal of Veterinary Medicine

A 5-year-old Pompitz presented with anorexia and vomiting. Radiographs showed a half-moon-shaped mass in the left cranial abdomen. A large cyst was identified near the left pancreas on ultrasound. Computed tomography revealed a fluid-attenuating mass with rim enhancement in the pancreas. Laboratory tests identified Staphylococcus warneri in the cystic lesion, and pancreatic pseudocyst with infection was suspected. The fluid accumulation and clinical signs recurred over several months. Pre-operative magnetic resonance imaging showed a hyperintense cystic lesion with a duct-like structure and hyperintense line between the cyst and the gastric wall on T2-weighted images as well as signal change of the …

Identifying The Potential Effect Of Zolmitriptan On The 1b Pathway Of Golgi Tendon Organs In Regulating Intermuscular Inhibition In The Extremities To Find A Link In The Mechanism Of Spasticity, Adam E. Davis, T. Richard Nichols

Research Day

The deep dorsal horn (DDH) of the spinal cord is a major integration center for receiving a variety of neural projections from the brainstem as well as a variety of afferent inputs from muscle spindles and Golgi tendon organs (GTOs) in the muscles. Following spinal cord injury (SCI) to the DDH, an overall loss of serotonergic input from the brainstem is observed, for which there is evidence to suggest that this may play a role in inhibiting the activity of bursting interneurons in the DDH, possibly leading to uncontrolled motoneuron activity, hyperreflexia. GTOs primarily supply the force feedback network (FBB), …

How can the integration and experience of Biophilic Design Principles bridge …

Rag Suppresses Group 2 Innate Lymphoid Cells, Aaron M Ver Heul, Madison Mack, Lydia Zamidar, Masato Tamari, Ting-Lin Yang, Anna M Trier, Do-Hyun Kim, Hannah Janzen-Meza, Steven J Van Dyken, Chyi-Song Hsieh, Jenny M Karo, Joseph C Sun, Brian S Kim

2020-Current year OA Pubs

Antigen specificity is the central trait distinguishing adaptive from innate immune function. Assembly of antigen-specific T cell and B cell receptors occurs through V(D)J recombination mediated by the Recombinase Activating Gene endonucleases RAG1 and RAG2 (collectively called RAG). In the absence of RAG, mature T and B cells do not develop and thus RAG is critically associated with adaptive immune function. In addition to adaptive T helper 2 (Th2) cells, group 2 innate lymphoid cells (ILC2s) contribute to type 2 immune responses by producing cytokines like Interleukin-5 (IL-5) and IL-13. Although it has been reported that RAG expression modulates the …

Patients diagnosed with metastatic triple negative breast cancer (mTNBC) have limited treatment options, are more prone to develop resistance and are associated with high mortality. A cold tumor immune microenvironment (TIME) characterized by low T cells and high tumor associated macrophages (TAMs) in mTNBC is associated with the failure of standard-of-care chemotherapy and immune checkpoint blockade (ICB) treatment. We demonstrate that the combination of immunomodulatory metronomic Cyclophosphamide (CTX) coupled with anti-CSF-1R antibody targeted therapy (SNDX-ms6352) and anti-PD-1 (ICB), was highly effective against aggressive metastatic syngeneic

Background: Tumor-associated macrophages (TAMs) are key promoters of inflammatory breast cancer (IBC), the most aggressive form of breast cancer. The receptor tyrosine kinase AXL is highly expressed in various cancer types, including IBC, but its role in TAMs remains unexplored.

Methods: We examined the effects of AXL inhibitor TP-0903 on tumor growth and tumor microenvironment (TME) component M2 macrophages (CD206+) in IBC and triple-negative breast cancer mouse models using flow cytometry and immunohistochemical staining. Additionally, we knocked out AXL expression in human THP-1 monocytes and evaluated the effect of AXL signaling on immunosuppressive M2 macrophage polarization and IBC cell growth …

Simplified Control Of Neuromuscular Stimulation Systems For Restoration Of Reach With Limb Stiffness As A Modifiable Degree Of Freedom, Tyler R Johnson, Chase A Haddix, A Bolu Ajiboye, Dawn M Taylor

Faculty, Staff and Student Publications

Objective. Brain-controlled functional electrical stimulation (FES) of the upper limb has been used to restore arm function to paralyzed individuals in the lab. Able-bodied individuals naturally modulate limb stiffness throughout movements and in anticipation of perturbations. Our goal is to develop, via simulation, a framework for incorporating stiffness modulation into the currently-used ‘lookup-table-based’ FES control systems while addressing several practical issues: (1) optimizing stimulation across muscles with overlap in function, (2) coordinating stimulation across joints, and (3) minimizing errors due to fatigue. Our calibration process also needs to account for when current spread causes additional muscles to become activated. Approach. …

A ‘Fluke’ Diagnosis: Suspecting Fascioliasis As A Rare Cause Of Hepatic Abscess, Tharun Shyam, Rosa Lora, Sharanya Kaushik, Jessica Chung, Monica Ghitan, Christina Coyle

Journal of Community Hospital Internal Medicine Perspectives

Hepatic abscess is a rare complication of fascioliasis, with fewer than 50 reported cases worldwide. The diagnosis requires a high degree of suspicion and is often identified after extensive investigation leading to delays in treatment. With this case report, we aim to highlight the need for a higher index of suspicion in non endemic regions like the USA, especially in cities with large immigrant populations. Given the ease and success rates of treatment with oral triclabendazole, the morbidity from unnecessary invasive testing and disease burden is preventable with a thorough evaluation and targeted clinical assessment.

Wild-Type Cardiac Amyloidosis Due To Transthyretin Protein — A Review, Mustafa Shehzad, Muhammad Hasan, Dawood Shehzad, Muhammad Shariq Akram, Muhammad Faiq Akram, Dawlat Khan, Maham Maqsood, Mamoon Ahmed, Humna Younis

Journal of Community Hospital Internal Medicine Perspectives

Transthyretin amyloid cardiomyopathy (ATTR-CM) arises from the accumulation of transthyretin amyloid fibrils in the myocardium, a consequence of instability and misfolding in wild-type or variant transthyretin protein. ATTR-CM should be suspected in older heart failure patients with raised myocardial wall thickness and diastolic dysfunction on echocardiography in the absence of hypertension or other known causes. This diagnosis can be further supported with late gadolinium enhancement on Cardiac MRI which indicates raised myocardial extracellular volume (ECV) hinting at the expansion of interstitial space by amyloid deposits. Diagnostic work up starts with blood and urine tests to rule out AL amyloidosis and …

Iron Deficiency—More Than Just Anemia: A Literature Review, Arianna S Moss, Zahra Pakbaz

Journal of Community Hospital Internal Medicine Perspectives

Iron deficiency (ID) is a global public health concern, as it can be a prodrome of gastrointestinal (GI) malignancies, exacerbate chronic conditions, and lead to an overall decreased quality of life. Despite being the most prevalent nutritional deficiency, it remains underdiagnosed by many healthcare professionals. Misconceptions regarding the clinical and laboratory manifestations of ID lead to delayed or missed diagnoses, contributing to poor patient outcomes. Though anemia is a commonly known consequence of ID, there are additional consequences that remain underrecognized by the medical community, including vague signs and symptoms, such as fatigue, depression, and abnormalities in white blood cell …

Catecholaminergic Polymorphic Ventricular Tachycardia-Linked Ryanodine Receptor Variants Exhibit Domain-Specific Calcium Leak And Calmodulin Affinity Properties, Hitoshi Uchinoumi, Xiaoqiong Dong, Ivanita Stefanon, Yi Yang, Eduardo Hertel Ribeiro, Bengt Svensson, Xander H T Wehrens, Takeshi Yamamoto, Razvan L Cornea, Robyn T Rebbeck, Masafumi Yano, Donald M Bers

Faculty, Staff and Students Publications

Catecholaminergic polymorphic ventricular tachycardia (CPVT) is an inherited stress-induced arrhythmogenic disease often caused by point variants in the cardiac ryanodine receptor (RyR2) that enhance diastolic sarcoplasmic reticulum (SR) Ca2+ leak. These RyR2 variants cluster in three hot-spots (N-terminal, central and C-terminal domains). We previously demonstrated a pathologic diastolic RyR2 conformation in heart failure, oxidative stress and CaMKII phosphorylation exhibiting a trilogy of effects: (1) reduced calmodulin (CaM)-RyR2 affinity, (2) enhanced unzipping peptide (DPc10) binding and (3) elevated diastolic SR Ca2+ leak that are dantrolene-sensitive. Here we test whether this pathological trilogy occurs in CPVT knock-in (KI) mice bearing N-terminal (R176Q/+), …

We conducted a systematic review and meta-analysis to estimate the prevalence of all types of glaucoma in Latin America (LATAM) and evaluate potential demographic associations. This study followed PRISMA guidelines and was registered in PROSPERO (CRD42024506330). A comprehensive search of PubMed, SciELO, and Web of Science was conducted to identify population-based or cross-sectional studies reporting glaucoma prevalence in LATAM. Studies were categorized into two groups: Group 1 included general population studies without selection based on visual acuity (VA), and Group 2 included studies limited to individuals with VA < 20/60. Data from five studies in Group 1 (25,288 individuals) and eight studies in Group 2 (29,882 individuals) were analyzed using R software. The pooled prevalence of glaucoma was 4% (95% CI: 1–3%) in Group 1 and 1% (95% CI: 0–1%) in Group 2. No statistically significant associations were found between glaucoma prevalence and sex (p = 0.08) or age (p = 0.5669). Although our findings …

Rescue Of The First Mitochondrial Membrane Carrier, The Mpic, By Tat-Mediated Protein Replacement Treatment, Samar Zabit, Orly Melloul, Michal Lichtenstein, Erin L. Seifert, Haya Lorberboum-Galski

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

The mitochondrial phosphate carrier (mPiC), encoded by the nuclear gene SLC25A3, is synthesized with an N-terminus mitochondrial targeting sequence (MTS), enabling its import into the mitochondria. mPiC imports inorganic phosphate (P_i) into the mitochondrial matrix for ATP production and other matrix phosphorylation reactions, as well as regulates mitochondrial Ca²⁺ uptake and buffering of matrix Ca²⁺. PiC also imports copper (Cu), crucial to COX subunit holoenzyme assembly. Variants in SLC25A3 exist and lead to mPiC deficiency (MPCD), cause a rare autosomal recessive disease with no current cure; patients with MPCD usually die within the first …

Patients with common variable immunodeficiency (CVID) who develop noninfectious complications (NIC) have worse clinical outcomes than those with infections only (INF). While gut microbiome aberrations have been linked to NIC, reductionist animal models that accurately recapitulate CVID are lacking. Our aim in this study was to uncover potential microbiome roles in the development of NIC in CVID. We performed whole-genome shotgun sequencing on fecal samples from CVID patients with NIC, INF, and their household controls. We also performed fecal microbiota transplants from CVID patients to germ-free mice. We found potentially pathogenic microbes
