Unique Case Of Spontaneous Basilar Artery Stroke In An Operated Child With Craniopharyngioma, Krishna Shah, Shrey Jain, Ajit K Sinha

Faculty, Staff and Students Publications

Craniopharyngiomas are the most commonly presented nonglial tumors in child patients. They cause significant morbidity and mortality, both before and after surgery. The most common immediate postsurgery complications are attributable to pituitary insufficiency. Neurovascular complications account for only 2.7 to 2.9% surgical cases, and usually involve the vessels of the Circle of Willis. Thrombosis or vasospasm of the vessels of posterior circulation is unheard of. Here, we are reporting a unique case of a child with craniopharyngioma who developed acute spontaneous basilar artery thrombosis and posterior circulation stroke 6 days after surgery.

A Rare Presentation Of Pericardial Tumor Presenting As Chronic Cough, Swarup Sharma Rijal, William H. Risher, Aakankshya Kharel, Upendra Kaphle

Advances in Clinical Medical Research and Healthcare Delivery

Chronic cough can pose various diagnostic and therapeutic dilemmas to physicians. Airway narrowing secondary to endoluminal disease or extrinsic compression are known etiologies of chronic cough. We report an extremely rare case of chronic cough due to extrinsic airway compression by a large pericardial lipoma with subsequent resolution of symptoms after the resection of the mass. This case provides insight into the rare etiology of chronic cough that is addressable with surgical intervention.

Hemoglobin As A Predictor For Covid-19 Disease Severity, Nicholas Sarcia, Dan Thai, Andrea M. Bodine Md

There is inconsistent data on Emergency Department (ED) hemoglobin levels and severity of disease. Our objective was to examine if COVID-19 patients presenting with abnormal hemoglobin levels have an increased risk of severe disease and in-hospital mortality.

Methods: We conducted a retrospective cohort study at Berkshire Medical Center in Pittsfield, MA to investigate the relationship of COVID-19 disease severity with hemoglobin level. Inclusion criteria consisted of ED patients over 18 years with …

Disease Severity In Covid-19 Breakthrough Cases, Dan Thai, Nicholas Sarcia, Andrea M. Bodine Md

Advances in Clinical Medical Research and Healthcare Delivery

Background

Vaccine breakthrough is a phenomenon wherein vaccinated individuals become infected with disease despite adequate protection. During this study period, the Centers for Disease Control (CDC) reported 66.6% of US people have been fully vaccinated. Any measures to improve trust would increase vaccination rates. This study aims to understand vaccine breakthrough cases in COVID-19 by comparing their severity to unvaccinated cases. Our objective is to compare disease severity based on the worst initial vital signs (temperature, respiratory rate, oxygen saturation), length of stay (LOS), and age between vaccinated and unvaccinated COVID-19 cases.

Methods

We conducted a retrospective cohort study at …

Constitutive Loss Of Dnmt3a Causes Morbid Obesity Through Misregulation Of Adipogenesis, Ayala Tovy, Jaime M Reyes, Linda Zhang, Yung-Hsin Huang, Carina Rosas, Alexes C Daquinag, Anna Guzman, Raghav Ramabadran, Chun-Wei Chen, Tianpeng Gu, Sinjini Gupta, Laura Ortinau, Dongsu Park, Aaron R Cox, Rachel E Rau, Sean M Hartig, Mikhail G Kolonin, Margaret A Goodell

Faculty, Staff and Students Publications

DNA Methyltransferase 3 A (DNMT3A) is an important facilitator of differentiation of both embryonic and hematopoietic stem cells. Heterozygous germline mutations in DNMT3A lead to Tatton-Brown-Rahman Syndrome (TBRS), characterized by obesity and excessive height. While DNMT3A is known to impact feeding behavior via the hypothalamus, here we investigated a role in adipocyte progenitors utilizing heterozygous knockout mice that recapitulate cardinal TBRS phenotypes. These mice become morbidly obese due to adipocyte enlargement and tissue expansion. Adipose tissue in these mice exhibited defects in preadipocyte maturation and precocious activation of inflammatory gene networks, including interleukin-6 signaling. Adipocyte progenitor cell lines lacking DNMT3A …

Poloxamer 407 Induces Hypertriglyceridemia But Decreases Atherosclerosis In Ldlr -/- Mice, Xueying Peng, Zeqin Lian, Xiao-Yuan Dai Perrard, Yunjie Xiao, Jing Ni, Veronica O'Brien, Henry Dong, Henry J Pownall, Christie M Ballantyne, Huaizhu Wu

Faculty, Staff and Students Publications

Background: Hypertriglyceridemia (HTG) increases the risk for atherosclerotic cardiovascular disease, but underlying mechanisms are incompletely understood. Circulating monocytes play an important role in atherogenesis by infiltrating arterial walls, where they differentiate into macrophages. We tested the hypothesis that HTG is mechanistically linked to atherogenesis by altering the monocyte phenotype and infiltration into atherosclerotic lesions in a model of diet-induced atherogenesis in Ldlr−/− mice. Methods: HTG was induced in male Ldlr−/− mice, fed a Western, high-fat high-cholesterol diet, by daily injection of poloxamer 407 (P407), a lipoprotein lipase inhibitor, for seven weeks. Atherosclerosis, monocyte phenotypes, and monocyte migration into atherosclerotic lesions …

Enriching The Perioperative Enhanced Recovery After Surgery (Eras) Program For Patients Undergoing Whipple Procedure For Pancreatic Cancer, Natalie E. Fisher

Doctor of Nursing Practice Final Manuscripts

Pancreatic cancer remains one of the most complex and lethal diseases worldwide with surgical resection as a major treatment choice. Although surgery may be one of the only options for advanced pancreatic cancer, it is not without a lengthy hospital stay, a long list of possible postoperative complications, and an increased risk for readmission after discharge. Enhanced recovery after surgery (ERAS) programs have been implemented for years in other surgical services for cancer care. These programs have now been extended and researched to include patients undergoing surgery for pancreatic cancer. These programs are designed to assist patients and their families …

Crel And Wnt5a/Frizzled 5 Receptor-Mediated Inflammatory Regulation Reveal Novel Neuroprotectin D1 Targets For Neuroprotection, Jorgelina M. Calandria, Khanh V. Do, Sayantani Kala-Bhattacharjee, Andre Obenaus, Ludmila Belayev, Nicolas G. Bazan

School of Medicine Faculty Publications

Abstract: Wnt5a triggers inflammatory responses and damage via NFkB/p65 in retinal pigment epithelial (RPE) cells undergoing uncompensated oxidative stress (UOS) and in experimental ischemic stroke. We found that Wnt5a-Clathrin-mediated uptake leads to NFkB/p65 activation and that Wnt5a is secreted in an exosome-independent fashion. We uncovered that docosahexaenoic acid (DHA) and its derivative, Neuroprotectin D1 (NPD1), upregulate c-Rel expression that, as a result, blunts Wnt5a abundance by competing with NFkB/p65 on the Wnt5a promoter A. Wnt5a increases in ischemic stroke penumbra and blood, while DHA reduces Wnt5a abundance with concomitant neuroprotection. Peptide inhibitor of Wnt5a binding, Box5, is also neuroprotective. DHA-decreased …

The Ventromedial Hypothalamic Nucleus: Watchdog Of Whole-Body Glucose Homeostasis, Longlong Tu, Makoto Fukuda, Qingchun Tong, Yong Xu

Children’s Nutrition Research Center Staff Publications

The brain, particularly the ventromedial hypothalamic nucleus (VMH), has been long known for its involvement in glucose sensing and whole-body glucose homeostasis. However, it is still not fully understood how the brain detects and responds to the changes in the circulating glucose levels, as well as brain-body coordinated control of glucose homeostasis. In this review, we address the growing evidence implicating the brain in glucose homeostasis, especially in the contexts of hypoglycemia and diabetes. In addition to neurons, we emphasize the potential roles played by non-neuronal cells, as well as extracellular matrix in the hypothalamus in whole-body glucose homeostasis. Further, …

The University of Louisville Journal of Respiratory Infections

Introduction: Hospital-based antimicrobial stewardship efforts have traditionally focused on inpatient settings. Antibiotic prescribing at discharge is often an overlooked area of focus for antimicrobial stewardship programs. Discharge prescribing optimization is necessary to combat antibiotic overuse.

Methods: This was an observational, retrospective cohort study at a four–adult community hospital system. Four hundred adult patients admitted with community-acquired pneumonia and discharged with antibiotics were included. The primary outcome was overall (inpatient and discharge) antibiotic length of therapy. The secondary outcome was percentage of patients discharged on a fluoroquinolone who had not received one in the hospital. Descriptive statistics were utilized.

Background: Sexually transmitted infections (STIs) during pregnancy are associated with adverse birth outcomes, including preterm birth, low birth weight, perinatal death, and congenital infections such as increased mother-to-child HIV transmission. Prevalence of STIs among pregnant women in South Africa remains high, with most women being asymptomatic for their infection(s). Unfortunately, most STIs remain undetected and untreated due to standard practice syndromic management in accordance with World Health Organization (WHO) guidelines. Although lab-based and point-of-care molecular tests are available, optimal screening strategies during pregnancy, their health impact, and cost-effectiveness are unknown. Methods: We will implement a 3-arm (1:1:1) type-1 hybrid effectiveness-implementation …

Expression Of 4e-Bp1 In Juvenile Mice Alleviates Mtor-Induced Neuronal Dysfunction And Epilepsy, Lena H Nguyen, Youfen Xu, Travorn Mahadeo, Longbo Zhang, Tiffany V Lin, Heather A Born, Anne E Anderson, Angélique Bordey

Faculty, Staff and Students Publications

Hyperactivation of the mTOR pathway during foetal neurodevelopment alters neuron structure and function, leading to focal malformation of cortical development and intractable epilepsy. Recent evidence suggests a role for dysregulated cap-dependent translation downstream of mTOR signalling in the formation of focal malformation of cortical development and seizures. However, it is unknown whether modifying translation once the developmental pathologies are established can reverse neuronal abnormalities and seizures. Addressing these issues is crucial with regards to therapeutics because these neurodevelopmental disorders are predominantly diagnosed during childhood, when patients present with symptoms. Here, we report increased phosphorylation of the mTOR effector and translational …

As the field of dance/ movement therapy evolves to meet the demands of a rapidly changing social landscape, it is imperative that clinicians think critically about the degree to which our work is steeped in oppressive frameworks and ideologies. This investigation uses testimony to explore epistemic injustice as it relates to the author’s experience of living with endometriosis and the pursuit of professional licensure. Considering the limited amount of research on the condition, along with the perceived absence of literature within the field of dance/ movement therapy, further study is warranted. The experimentation phase of this research incorporated the use …

How Environmental Change Will Impact Mosquito-Borne Diseases, Arsal Khan

Master's Projects and Capstones

Mosquitos, the most lethal species throughout human history, are the most prevalent source of vector-borne diseases and therefore a major global health burden. Mosquito-borne disease incidence is expected to shift with environmental change. These changes can be predicted using species distribution models. With the wide variety of methods used for models, consensus for improving accuracy and comparability is needed. A comparative analysis of three recent modeling approaches revealed that integrating modeling techniques compensates for trade-offs associated with a singular approach. An area that represents a critical gap in our ability to predict mosquito behavior in response to changing climate factors, …

A Novel Approach Toward Concussion Testing, Jorge K. Mercado, Ari Schacter, Danielle Euzent

Student Theses

A concussion is a violent jarring or shaking of the head caused by whiplash or direct impact that results in a disturbance of brain function. Concussions can be mild and brief, as a person may be dazed momentarily or can be more serious, resulting in a loss of consciousness. Underreporting of concussions is prevalent because they are a symptom-based diagnosis, lacking a clinical test. In this study, we investigated the use of VNG testing as a clinical diagnosis of concussions. Looking at the VNG test battery, the previous research cohort found that saccades, gaze, and positional testing are the most …

Faculty, Staff and Student Publications

Pirtobrutinib (LOXO-305), a reversible inhibitor of Bruton's tyrosine kinase (BTK), was designed as an alternative strategy to treat ibrutinib-resistant disease that develops due to C481 kinase domain mutations. The clinical activity of pirtobrutinib has been demonstrated in CLL, but the mechanism of action has not been investigated. We evaluated pirtobrutinib in 4 model systems: first, MEC-1, a CLL cell line overexpressing BTKWT, BTKC481S, or BTKC481R; second, murine models driven by MEC-1 overexpressing BTKWT or BTKC481S; third, in vitro incubations of primary CLL cells; and finally, CLL patients during pirtobrutinib therapy (NCT03740529, ClinicalTrials.gov). Pirtobrutinib inhibited BTK activation as well …

Alterations Of The Gut Microbial Community Structure And Function With Aging In The Spontaneously Hypertensive Stroke Prone Rat, Huanan Shi, James W Nelson, Sharon Phillips, Joseph F Petrosino, Robert M Bryan, David J Durgan

Faculty, Staff and Students Publications

Gut dysbiosis, a pathological imbalance of bacteria, has been shown to contribute to the development of hypertension (HT), systemic- and neuro-inflammation, and blood-brain barrier (BBB) disruption in spontaneously hypertensive stroke prone rats (SHRSP). However, to date individual species that contribute to HT in the SHRSP model have not been identified. One potential reason, is that nearly all studies of the SHRSP gut microbiota have analyzed samples from rats with established HT. The goal of this study was to examine the SHRSP gut microbiota before, during, and after the onset of hypertension, and in normotensive WKY control rats over the same …

Integrative Genomic Analysis Reveals Low T-Cell Infiltration As The Primary Feature Of Tobacco Use In Hpv-Positive Oropharyngeal Cancer, Benjamin M Wahle, Paul Zolkind, Ricardo J Ramirez, Zachary L Skidmore, Sydney R Anderson, Angela Mazul, D Neil Hayes, Vlad C Sandulache, Wade L Thorstad, Douglas Adkins, Obi L Griffith, Malachi Griffith, Jose P Zevallos

Although tobacco use is an independent adverse prognostic feature in HPV(+) oropharyngeal squamous cell carcinoma (OPSCC), the biologic features associated with tobacco use have not been systematically investigated. We characterized genomic and immunologic features associated with tobacco use through whole exome sequencing, mRNA hybridization, and immunohistochemical staining in 47 HPV(+) OPSCC tumors. Low expression of transcripts in a T cell-inflamed gene expression profile (TGEP) was associated with tobacco use at diagnosis and lower overall and disease-free survival. Tobacco use was associated with an increased proportion of T > C substitutions and a lower proportion of expected mutational signatures, but not with …
