Rare Case Of Hemorrhagic Pericardial Effusion Due To Coxsackie B Pericarditis, Nolan Shoukri, Hazem Alakhras, Kateryna Strubchevska, Steven Timmis May 2024

Rare Case Of Hemorrhagic Pericardial Effusion Due To Coxsackie B Pericarditis, Nolan Shoukri, Hazem Alakhras, Kateryna Strubchevska, Steven Timmis

Conference Presentation Abstracts

Introduction Acute pericarditis is caused by inflammation of the pericardial sac. Amongst the vast number of potential causes, viruses tend to trigger pericarditis most frequently. Some of the more common viral causes are coxsackie A/B, echovirus, adenovirus, CMV, HSV, and HIV.1-3 Pericarditis often presents with signs and symptoms such as a friction rub, pain relieved with sitting up and leaning forward. ST segment elevations and PR segment depressions are seen on EKG. Laboratory tests showed increased inflammatory markers and WBC count. Pericardial effusion is a common complication and can be visualized on echocardiogram. In some cases, the pericardial effusion can …


Non-Immune Hemolytic Anemia In The Setting Of Alcohol-Associated Hepatitis: Zieve's Syndrome, Morgan Kiryakoza, Nazli Begum Ozturk, Justin Skrzynski May 2024

Non-Immune Hemolytic Anemia In The Setting Of Alcohol-Associated Hepatitis: Zieve's Syndrome, Morgan Kiryakoza, Nazli Begum Ozturk, Justin Skrzynski

Conference Presentation Abstracts

Introduction: Zieve’s syndrome describes a triad of non-immune hemolytic anemia, jaundice, and transient hyperlipidemia found in patients with alcohol-use disorder/alcohol-associated liver disease. This case involves a 39-year-old female with suspected Zieve’s syndrome in the setting of severe alcohol-associated hepatitis. Case Description: A 39-year-old female with alcohol-use disorder presented to the emergency department with complaints of jaundice, lethargy, and confusion. On initial presentation, patient was anemic with a hemoglobin of 7.8 g/dL (12.1- 15.0 g/dL), ALP of 235 U/L (33-120 U/L), AST of 116 U/L (< 35 U/L), ALT of 41 (< 37 U/L) total bilirubin of 24.2 mg/dL (< 1.2mg/dL), direct bilirubin of >15 mg/dL (< 0.4mg/dL). Her blood alcohol level was negative. She was admitted due to concerns for alcohol-associated hepatitis. Her hospital course was complicated by frequent declines in hemoglobin requiring a total of six transfusions of packed red blood cells. No overt bleeding such as hematemesis or hematochezia was ever evident during these declines. Further hematologic workup revealed a normal glucose 6 phosphate dehydrogenase (G6PD), normal pyruvate kinase, elevated plasma hemoglobin of 150 mg/dL (< 30 mg/dL), decreased haptoglobin of < 8 mg/dL (40-250 mg/dL), and elevated lactate dehydrogenase (LDH) of 595 (100-240 U/L), elevated reticulocyte count of 213 bil/L (21-100 bil/L). Direct Coombs Test was negative. The combination of these labs illustrated a picture of non-immune hemolytic anemia. Patient’s course was further complicated by a persistent rise in her total bilirubin, eventually peaking at 30.6 mg/dL, and ascites which required paracentesis and fluid studies was consistent with spontaneous bacterial peritonitis (SBP). Given the presence of SBP, corticosteroid therapy was not initiated for alcohol-associated hepatitis. Lipid panel remained within normal limits on two separate occasions. Vitamin E level was < 2.5 mg/L (5.5 – 17.0 mg/L). During hospitalization, she tested positive for Influenza A H1N1, developed acute hypoxic respiratory failure, was intubated, and was transferred to the intensive care unit and later extubated. Her mental status during her hospital stay was frequently waxing and waning and never fully recovered. The patient was eventually discharged home with hospice and her hemoglobin levels remained stable after supportive blood transfusions during her stay. Discussion: Zieve’s syndrome is an underdiagnosed cause of anemia in patients with alcohol-associated liver disease. There are multiple proposed mechanisms to explain the pathophysiology behind the red cell lysis seen in this disorder. One leading hypothesis suggests the red cell membrane becomes unstable due to vitamin E deficiency leading to disordered pyruvate kinase. Importance of early recognition of this syndrome is essential as treatment revolves around strict abstinence from alcohol.

Splenic Infarct Following Roux-En-Y Gastric Bypass Surgery, Khurram Arshad, Yazan Alamro, Rabia Latif, Zaid Mahameed, Omar Nasser Rahal, Rajiv John

Conference Presentation Abstracts

Introduction: Roux-en-Y gastric bypass (RYGB) is a standard surgical procedure used to treat morbid obesity. Although RYGB is generally considered safe, it's essential to remain vigilant in identifying and addressing rare complications such as splenic infarction. Splenic infarction is a primarily silent condition, and because many cases go undiagnosed, the exact incidence of the condition is obscure and likely underestimated. Similarly, the incidence and severity of these rare conditions in the postoperative period for bariatric surgeries are still unknown. Case presentation: A 31-year-old female with morbid obesity underwent RYGB six weeks before presentation with acute abdominal pain, nausea, and a …

Background: Hippocampal avoidant whole brain radiotherapy (HA-WBRT) is the standard of care for patients needing WBRT for brain metastases. This study, using existing data from NRG Oncology CC001 including baseline tumor characteristics and patient-reported MD Anderson Symptom Inventory-Brain Tumor (MDASI-BT) scores, sought to identify subgroups of patients that demonstrate differential neuroprotective treatment response to HA-WBRT.

Methods: An exploratory analysis of NRG CC001, a phase 3 trial in which 518 patients were randomly assigned to WBRT plus memantine or HA-WBRT plus memantine, was performed. Rates of neurocognitive function failure (NCFF) were estimated between subgroups and stratified by arm. Covariate and subgroup …

Targeted therapy is effective in many tumor types including lung cancer, the leading cause of cancer mortality. Paradigm defining examples are targeted therapies directed against non-small cell lung cancer (NSCLC) subtypes with oncogenic alterations in EGFR, ALK and KRAS. The success of targeted therapy is limited by drug-tolerant persister cells (DTPs) which withstand and adapt to treatment and comprise the residual disease state that is typical during treatment with clinical targeted therapies. Here, we integrate studies in patient-derived and immunocompetent lung cancer models and clinical specimens obtained from patients on targeted therapy to uncover a focal adhesion kinase (FAK)-YAP signaling …

Patients with cytogenetically normal acute myeloid leukemia (CN-AML) may harbor prognostically relevant gene mutations and thus be categorized into one of the three 2022 European LeukemiaNet (ELN) genetic-risk groups. Nevertheless, there remains heterogeneity with respect to relapse-free survival (RFS) within these genetic-risk groups. Our training set included 306 adults on Alliance for Clinical Trials in Oncology studies with de novo CN-AML aged <  60 years who achieved a complete remission and for whom centrally reviewed cytogenetics, RNA-sequencing, and gene mutation data from diagnostic samples were available (Alliance trial A152010). To overcome deficiencies of the Cox proportional hazards model when long-term survivors are present, we developed a penalized semi-parametric mixture cure model (MCM) to predict RFS where RNA-sequencing data comprised the predictor space. To validate model performance, we employed an independent test set from the German Acute Myeloid Leukemia Cooperative Group (AMLCG) consisting of 40 de novo CN-AML patients aged <  60 years who achieved a complete remission and had RNA-sequencing of their pre-treatment sample. For the training set, there was a significant non-zero cure fraction (p = 0.019) with 28.5% of patients estimated to be cured. Our MCM included 112 genes associated with cure, or long-term RFS, and 87 genes associated with latency, or shorter-term time-to-relapse. The area under the curve and C-statistic were respectively, 0.947 and 0.783 for our training set and 0.837 and 0.718 for our test set. We identified a novel, prognostically relevant molecular signature in CN-AML, which allows identification of patient subgroups independent of 2022 ELN genetic-risk groups.Trial registration Data from companion studies CALGB 8461, 9665 and 20202 (trials registered at www.clinicaltrials.gov as, respectively, NCT00048958, NCT00899223, and NCT00900224) were obtained from Alliance for Clinical Trials in Oncology under data sharing study A152010. Data from the AMLCG 2008 trial was registered at www.clinicaltrials.gov as NCT01382147.

Meningomyelocele is one of the most severe forms of neural tube defects (NTDs) and the most frequent structural birth defect of the central nervous system. We assembled the Spina Bifida Sequencing Consortium to identify causes. Exome and genome sequencing of 715 parent-offspring trios identified six patients with chromosomal 22q11.2 deletions, suggesting a 23-fold increased risk compared with the general population. Furthermore, analysis of a separate 22q11.2 deletion cohort suggested a 12- to 15-fold increased NTD risk of meningomyelocele. The loss of

AMPA (α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid) receptors (AMPARs) mediate fast excitatory neurotransmission in the brain. AMPARs form by homo- or heteromeric assembly of subunits encoded by the GRIA1–GRIA4 genes, of which only GRIA3 is X-chromosomal. Increasing numbers of GRIA3 missense variants are reported in patients with neurodevelopmental disorders (NDD), but only a few have been examined functionally.

Here, we evaluated the impact on AMPAR function of one frameshift and 43 rare missense GRIA3 variants identified in patients with NDD by electrophysiological assays. Thirty-one variants alter receptor function and show loss-of-function or gain-of-function properties, whereas 13 appeared neutral.

We collected detailed …

The morpholine heterocycle is a structural unit found in many bioactive compounds and FDA-approved drugs, but the generation of more complex C-functionalized morpholine derivatives remains considerably underexplored. Using systematic chemical diversity (SCD), a concept that guides the expansion of saturated drug-like scaffolds through regiochemical and stereochemical variation, we describe the synthesis of a collection of methyl-substituted morpholine acetic acid esters starting from enantiomerically pure amino acids and amino alcohols. In total, 24 diverse substituted morpholines were produced that vary systematically in regiochemistry and stereochemistry (relative and absolute). These diverse C-substituted morpholines can be directly applied in fragment screening or incorporated …

Loss-of-function mutation of ABCC9, the gene encoding the SUR2 subunit of ATP sensitive-potassium (KATP) channels, was recently associated with autosomal recessive ABCC9-related intellectual disability and myopathy syndrome (AIMS). Here we identify nine additional subjects, from seven unrelated families, harbouring different homozygous loss-of-function variants in ABCC9 and presenting with a conserved range of clinical features. All variants are predicted to result in severe truncations or in-frame deletions within SUR2, leading to the generation of non-functional SUR2-dependent KATP channels. Affected individuals show psychomotor delay and intellectual disability of variable severity, microcephaly, corpus callosum and white matter abnormalities, seizures, spasticity, short stature, muscle …

Sarcopenia burdens the older population through loss of muscle energy and mass, yet treatments to functionally rescue both parameters are lacking. The glucocorticoid prednisone remodels muscle metabolism on the basis of frequency of intake, but its mechanisms in sarcopenia are unknown. We found that once-weekly intermittent prednisone administration rescued muscle quality in aged 24-month-old mice to a level comparable to that seen in young 4-month-old mice. We discovered an age- and sex-independent glucocorticoid receptor transactivation program in muscle encompassing peroxisome proliferator-activated receptor γ coactivator 1 α (PGC1α) and its cofactor Lipin1. Treatment coordinately improved mitochondrial abundance through isoform 1 and …

Implementation Of A Validated Suicide Screening Tool In A University Student Health Center, Tessa Welniak, Bailey Coslor, Cathrin Carithers

Doctor of Nursing Practice Projects: College of Nursing

Purpose. Suicide is the second leading cause of death among adults in the United States and Nebraska. Death by suicide impacts millions of adults every year in the United States but warning signs are often missed during visits with primary care providers. The University of Nebraska at Kearney (UNK) Student Health Center (SHC), like many other primary care clinics, did not routinely screen patients for suicide risk. According to the Joint Commission, all patients over 12 years of age should be screened for suicide using a validated screening tool if the visit is for any behavioral health concern.

Implementing A Standardized Protocol For Early Detection Of Undiagnosed Hypertension Patients, Jenscena Hansen, Chris Bell

Doctor of Nursing Practice Projects: College of Nursing

Introduction: Hypertension is a preventable disease that frequently goes unrecognized and undertreated. Early diagnosis can prevent further comorbidities such as heart disease, stroke, and chronic kidney disease. Implementation of this protocol aims to decrease the number of patients with undiagnosed hypertension and increase the identification of patients with elevated blood pressure who did not have a pre-existing diagnosis of hypertension. The goal of implementing a standardized protocol would help eliminate the number of patients who go undiagnosed.

Methods: This quality improvement design had clinical staff flag patients with elevated blood pressure. Identified patients without a diagnosis of hypertension were educated …


Unplanned Pregnancy As An Independent Risk Factor For Antepartum Si In A Post Roe Vs. Wade World, Rianna Mcnamee May 2024

Unplanned Pregnancy As An Independent Risk Factor For Antepartum Si In A Post Roe Vs. Wade World, Rianna Mcnamee

Rowan-Virtua Research Day

Abstract: The objective of this literature review is to determine whether unplanned pregnancy is an independent risk factor for developing antepartum SI. Background: The Supreme Court of the United States of America recently ruled that the constitution of the United States does not confer a right to abortion to its citizens. As of October 2023, twenty-one states had developed full or partial bans on abortion, resulting in millions of Americans residing in areas where terminating unplanned pregnancy is not a viable option. There is evidence that indicates antepartum suicidal ideation (SI) is higher than that of the general population, however …

Introduction: Non-alcoholic fatty liver disease (NAFLD) is the most common form of chronic liver disease in the United States and has been found to play a significant role in cardiovascular disease risk through several mechanisms including dyslipidemia, insulin resistance, coagulability, and inflammation. Acute-on-chronic liver disease continues to contribute to worse health outcomes via acute hepatitis.

Methods: This case-control study investigated the relationship between NAFLD and acute hepatitis using data extracted from the National Inpatient Sample (NIS) Database for the years 2019 and 2020. The NIS was searched for hospitalizations of adult patients with acute hepatitis with and without NAFLD. Using …

It is theorized that low concentrations of dopamine (DA) and norepinephrine (NE) within in the prefrontal cortex (PFC) following traumatic brain injury (TBI) leads to increased risky behavior. Our lab has shown that repeated mild TBI (rmTBI) sex-differentially increases risky behavior in a rodent model. Methylphenidate (MPH) is a psychostimulant drug used to treat symptoms of Attention-Deficit Hyperactivity Disorder (ADHD), also driven by a hypo-catecholaminergic PFC. MPH elevates catecholamine levels by blocking DA and NE transporters, DAT and NET. While the potential of psychostimulants to treat post-TBI symptoms have been explored, the effects of sub-chronic MPH on transporter levels following …

Hemiplegic migraine (HM) is a rare subtype of migraine with both familial and sporadic patterns. These migraines present episodically with reversible attacks of unilateral motor weakness. Patients may experience visual changes, sensory loss, impaired level of consciousness, ataxia, and speech changes. Symptoms can last from hours to days and can mimic acute stroke.

The patient is a 45-year-old male with a past medical history of hypertension and possible cerebral vascular accident use who presents to the emergency department complaining of left extremity numbness and weakness. Neuroimaging showed no acute findings and CT angiogram showed no large vessel occlusion. Tenecteplase was …

Patients suffering from Parkinson’s Disease will typically experience a range of motor and nonmotor symptoms. Characteristic signs of Parkinson’s include pill-rolling tremor, stooped posture, and shuffling gate. Patients with this disease can also develop oropharyngeal dysfunction, which can disable patients from meeting their physiologic needs. Understanding this disability and the changes in mastication kinematics can lead to potential future treatment. Our study induced Parkinson’s in rats with rotenone injections. Their jaw kinematics were identified through fluoroscopy of radio-opaque beads implanted into different areas of their jaws. The Parkinson’s induction altered mastication significantly with an increase in anterior/posterior range of motion …

Parkinson’s disease is a neurodegenerative disorder known to cause dysphagia, the major contributor to mortality via aspiration pneumonia. The neurological basis of swallowing dysfunction in Parkinson patients is poorly understood. To explore the mechanisms of swallowing dysfunction, we studied the impact of rotenone treatment on respiration rate and swallowing rate in liquid-drinking rats. We hypothesized that rotenone treatment will cause a decrease in respiratory and swallowing rate compared to untreated liquid-drinking rats. Six rats were injected with 2.75 mg/kg/day intraperitoneal rotenone for 16 days to create the parkinsonian phenotype and subsequently recorded with 200fps video fluoroscopy during barium-infused liquid drinking. …

Introduction: Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is considered the most advanced temporary life support which provides complete hemodynamic support in addition to gas exchange. There is limited data available on the impact of hyperlipidemia (HLD) on VA-ECMO patients. We sought to examine the national inpatient sample (NIS) database to describe in-hospital outcomes among these patients.

Methods: The NIS was searched for hospitalizations of adult VA-ECMO patients with and without a concomitant diagnosis of HLD for the years 2019 and 2020. The primary outcome was inpatient mortality.

Results:This study included 3,885 VA-ECMO patients, of which 1,082 (27.8%) patients had HLD. …
