Chronic Nucleoside Reverse Transcriptase Inhibitors Disrupt Mitochondrial Homeostasis And Promote Premature Endothelial Senescence, Yi-Fan Chen

LSU Doctoral Dissertations

Combination antiretroviral therapy (cART) has been hugely successful in reducing the mortality associated with human immunodeficiency virus (HIV) infection, resulting in a growing population of people living with HIV (PLWH). Since PLWH now have a longer life expectancy, chronic comorbidities have become the focus of the clinical management of HIV. For example, cardiovascular complications are now one of the most prevalent causes of death in PLWH. Nucleoside reverse transcriptase inhibitors (NRTIs) are the backbone of cART, and two NRTIs are typically used in combination with one drug from another drug class, such as a non-NRTI, a protease inhibitor or an …

Divergent Transcriptional Regulation Of Suppressors Of Cytokine Signaling Genes In Adipocytes, Paula Mota De Sa

LSU Doctoral Dissertations

The Janus Kinase - Signal Transducer and Activator of Transcription (JAK-STAT) signaling pathway transduces several signals crucial for development and homeostasis. Suppressors of cytokine signaling (SOCS) proteins control JAK-STAT signaling via a negative feedback loop. The transcription factor STAT5 is known to play a significant role in fat cell development and function, and several studies suggest that acetylation may affect STAT5 transcriptional activity. To test this hypothesis, we treated 3T3-L1 adipocytes with growth hormone (GH) to activate STAT5 in the presence or absence of histone deacetylase (HDAC) inhibitors. STAT5 acetylation levels were low in adipocytes and mostly unchanged by the …

Development Of Cs-Tpp-Dsrna Nanoparticles To Enhance Rnai Efficiency In The Yellow Fever Mosquito, Aedes Aegypti, Ramesh Kumar Dhandapani, Dhandapani Gurusamy, Jeffrey L. Howell, Subba Reddy Palli

Entomology Faculty Publications

Mosquito-borne diseases are a major threat to human health and are responsible for millions of deaths globally each year. Vector control is one of the most important approaches used in reducing the incidence of these diseases. However, increasing mosquito resistance to chemical insecticides presents challenges to this approach. Therefore, new strategies are necessary to develop the next generation vector control methods. Because of the target specificity of dsRNA, RNAi-based control measures are an attractive alternative to current insecticides used to control disease vectors. In this study, Chitosan (CS) was cross-linked to sodium tripolyphosphate (TPP) to produce nano-sized polyelectrolyte complexes with …

Postoperative Pain: Factors And Tools To Improve Pain Management In Children, Mai M. Makhlouf, Eric Robles Garibay, Brooke N. Jenkins, Zeev N. Kain, Michelle Fortier

Psychology Faculty Articles and Research

Outpatient surgery has made it increasingly common for parents to manage pain in the home setting. Studies have shown that parents often under treat pain, leaving children vulnerable to the negative side effects of suboptimal pain management. Multiple factors affect pain management like child’s age and developmental stage, language, cultural values like stoicism, parental beliefs about medication, biological differences among groups, etc. Understanding all the factors involved can help healthcare providers and parents better understand pain and contribute to optimal pain management. Multiple tools and technological interventions have been created to help create a better understanding of pain and a …

Testosterone Levels In Men With Chronic Migraine, Lisa B. E. Shields, Tad Seifert, Brent J. Shelton, Brian M. Plato

Markey Cancer Center Faculty Publications

Chronic migraine is a frequent and debilitating condition affecting 14% of the general population. This prospective observational pilot study investigated whether men with chronic migraine have lower than expected total serum testosterone levels. We identified 14 men ages 26-51 at our Institution who fulfilled the ICHD-3b criteria for chronic migraine and obtained serum total testosterone levels. The mean total testosterone level in our 14 patients was 322 ng/dL (range: 120-542 ng/dL) which is in the lower 5% of the reference range for our laboratory (300-1080 ng/dL). Men with chronic migraine had lower total testosterone levels compared to published agematched normative …

Emotional Inferencing In Children With Language Impairment, Allison Barney, Bonnie Brinton

Journal of Undergraduate Research

Children with language impairment (LI) present with “a significant impairment in the acquisition and use of language across modalities” (ASHA, 1993). LI is a prevalent disorder affecting 7% of kindergarteners (Tomblin et al, 1997). LI limits a child’s ability to acquire language, to establish relationships with others, and to succeed in school. In addition, children with LI experience a range of social problems including withdrawal, exclusion, and peer victimization (Fujiki & Brinton, 2017). Recent research has indicated that children with LI have particular difficulty with emotion understanding (Brinton & Fujiki, 2014; Spackman, Fujiki, & Brinton, 2006). That is, they struggle …

Stat3 Genotypic Variant Rs744166 And Increased Tyrosine Phosphorylation Of Stat3 In Il-23 Responsive Innate Lymphoid Cells During Pathogenesis Of Crohn's Disease, Ying Tang, Sanda A. Tan, Atif Iqbal, Jian Li, Sarah C. Glover

Department of Neurology Faculty Papers

Crohn's disease (CD) results from dysregulated immune responses to gut microbiota in genetically susceptible individuals, affecting multiple areas of the gastrointestinal tract. Innate lymphoid cells (ILCs) are tissue-resident innate effector lymphocytes which play crucial roles in mucosal immune defense, tissue repair, and maintenance of homeostasis. The accumulation of IFN-γ-producing ILC1s and increased level of proinflammatory cytokines produced by ILCs has been observed in the inflamed terminal ileum of CD patients. To date, the precise mechanisms of ILC plasticity and gene regulatory pathways in ILCs remain unclear. Signal transducer and activator of transcription 3 (STAT3) regulates gene expression in …

In Vitro Evaluation Of Ovarian Cancer Tumorigenesis As A Function Of Quinone Oxidoreducatse-1 And Cell Phenotype, Milcah S. Jackson

LSU Doctoral Dissertations

In vitro multicellular spheroids are attractive model systems for assessing genetic and epigenetic changes that occur in diseased tissues. Understanding how such alterations in gene and subsequent protein expression affect disease progression and metastasis, drug resistance, and recurrence is of great interest in cancer research. In this regard, examining expression and activity of proteins, such as those with cytoprotective ability that are overexpressed in cancer cells, in addition to cell phenotype (i.e., stem-like, epithelial, mesenchymal, or mixed), are two ways to evaluate genetic and epigenetic changes. Moreover, determining the impact that cytoprotective proteins and cell phenotype have on tumor formation …

Introduction

Heart failure with preserved ejection fraction (HFpEF) is a clinical syndrome in which a patient has signs and symptoms of heart failure including dyspnea, fatigue, pulmonary rales, peripheral edema and an ejection fraction greater than 50%.1-4 Approximately half of patients with heart failure have a preserved ejection fraction.2-5 HFpEF is considered a distinct clinical entity from other causes of heart failure with a preserved ejection fraction such as valvular heart disease, pericardial disease, and infiltrative cardiomyopathy. HFpEF carries a poor prognosis, with an annual mortality of 29% in patients discharged after an acute decompensated heart failure admission.5 5-year survival …

A Gram-Negative False-Negative: Normal Procalcitonin Level In A Patient With Multiple Klebsiella Pneumoniae Intra-Abdominal Abscesses: A Case Report And Literature Review, Mario Caldararo, Md

The Medicine Forum

Introduction

Despite over 3,000 peer-reviewed articles on procalcitonin (PCT) since 2004, guidance on its usage is sparse.1 An analysis of more than 500 United States hospitals in the Premier Healthcare Database found large differences in utilization exist across regions (115 PCT encounters per 10,000 patients in the Northeast vs. 408 to 576 in other regions) and teaching vs. non-teaching hospitals (345 vs. 530 PCT encounters per 10,000 patients, respectively).2 The purpose of this work is to describe a case that exemplifies the caveats in PCT interpretation and to summarize the current knowledge of the clinical utilization of PCT.

Resident Experiences With Journaling, Tara Sunder, Md, Gretchen Diemer, Md, Vikas Sunder, Md

The Medicine Forum

Background

Each year, medical school graduates don their long white coat for the first time and begin their residency. While residency promises the excitement of learning and increased autonomy, it also brings long duty hours and stressful situations worsened by inexperience. Due to these stressors, burnout affects many residents each year. Studies have been done to see if wellness curricula help decrease resident burnout, and since journaling is a known way to relieve stress and enhance reflection, journaling has become a common intervention in these curricula.1,2 While there are studies evaluating the impact of journaling on mental health and stress …

Pneumatosis Intestinalis In A Patient With Systemic Lupus Erythematosus, Sean Dikdan, Md, Michael Lake, Md

The Medicine Forum

Introduction

Pneumatosis intestinalis (PI) refers to the radiographic finding of gas within the small or large bowel wall. It can be seen in association with gas in the portal venous system. The clinical significance of these findings is variable and depends on the patient's etiology and initial presentation. PI can be seen anywhere in the gastrointestinal tract distal to the stomach and is caused by a myriad of conditions.1 We present a case of a patient admitted to the intensive care unit with PI and portal vein gas.

Hemothorax And Hemorrhagic Ascites: A Rare Presentation Of Endometriosis, Harry Wang, Md

The Medicine Forum

Introduction

Endometriosis is a common diagnosis in reproductive age women characterized by the presence of endometrial tissue outside the uterine cavity.1 Although it is typically confined to the pelvis, rare manifestations involving the thorax, abdomen or pericardium have been documented.2-5 Even more rare is the concurrent presence of endometriosis- associated hemorrhagic pleural effusion and ascites, which can prove a diagnostic challenge. We describe a case of hemothorax and hemorrhagic ascites in a woman with shortness of breath and abdominal pain.

Subacute Onset Hand Clumsiness In A Renal Transplant Patient With A Recent Icu Stay, William Bradford, Md

The Medicine Forum

Introduction

Solid organ transplant recipients carry a high burden of disease and are susceptible to opportunistic infections not seen in other patient subgroups. Signs and symptoms that would not necessarily warrant timely attention in other patient groups may call for an aggressive workup in this subset of patients. Here, we present one case in which a seemingly trivial complaint denoted serious underlying pathology, and timely attention to this minor but unusual concern led to early intervention with appropriate treatment of an uncommon disorder.

Hyperviscosity In Non-Igm Lymphoplasmacytic Lymphoma, Mario Fonseca-Paricio, Md, Sushil Chmire, Md, Adam Binder, Md

The Medicine Forum

The following is a case of how a non-IgM paraproteinemia can present with symptoms of hyperviscosity and coagulopathy, an uncommon occurrence.1-3 As this case demonstrates, this diagnosis must be considered even in patients with relatively normal coagulation laboratory results. Such pathology requires urgent treatment with plasmapheresis.

Worsening Autoimmune Neutropenia After Stopping Ibrutinib In A Patient With Chronic Lymphocytic Leukemia: Case Report And Review Of Literature, Natalie Rosen, Ba, Thomas Klumpp, Md, Sameh Gaballa, Md, Msc

The Medicine Forum

Introduction

Autoimmune cytopenia (AIC) is relatively common in patients with chronic lymphocytic leukemia occurring in 5-10% of patients during the course of their disease.1 Autoimmune hemolytic anemia (AIHA) constitutes the highest prevalence (5-10%) of CLL-associated AIC followed by idiopathic thrombocytopenic purpura (ITP) (2-5%), pure red cell aplasia (PRCA) (<1%), and autoimmune neutropenia (AIN) (<1%).2,3 The prevalence of AIN, however, may in fact be higher than reported due to a lack of awareness of the condition and difficulty in its diagnosis.4 Despite its rarity, autoimmune neutropenia can be a significant clinical challenge in patients with CLL and can increase the risk of infectious complications. Thus, the prompt diagnosis and resolution of CLL-associated AIN is essential to the management of these patients.

Ibrutinib is a selective inhibitor of Bruton tyrosine kinase and induces a durable response in patients with CLL.5 The activity of ibrutinib in CLL-associated AIC is largely unknown as pivotal clinical trials excluded patients with AIC. We report a case of a patient with CLL who experienced worsening of AIN after …

Bilateral Choroidal Metastases As Initial Presentation Of Widespread Follicular Thyroid Cancer, Jennifer Hong, Md

The Medicine Forum

Introduction

Follicular thyroid cancer (FTC) is the second most common malignancy of the thyroid gland and comprise 10-15% of all thyroid tumors; the usual mode of spread is via hematogenous dissemination with the most common sites of metastases being the lungs and bones.4 A case is presented to demonstrate the unusual presentation of follicular thyroid cancer as bilateral choroidal metastases. Although exceptional, a diagnosis of choroidal metastases should be considered in any decline in visual acuity in patients with thyroid cancer.

Complicated Persistent Peritonitis, Lindsey Roth, Ba, Kumar Sarkar, Md

The Medicine Forum

Introduction

Spontaneous bacterial peritonitis (SBP) is a common complication of end-stage liver disease. SBP can present with many symptoms such as abdominal pain, fever and altered mental status.1 The diagnosis of SBP is made when ascitic fluid from a paracentesis has an absolute neutrophil count (ANC) more than 250/uL, there is a positive ascitic fluid culture, and no secondary source of infection can be idenitifed.2 However, nearly 60% of patients with SBP have negative fluid cultures.3 These patients can still potentially have SBP and should be treated as such since in-hospital mortality ranges from 20-40%.1,4 Conventional treatment for SBP includes …

Sealing The Diagnosis Of Celiac Disease In Pregnancy, Ritu Nahar, Md, Avani Aman, Md

The Medicine Forum

Introduction

Celiac disease (CD) is an immune mediated condition that results from a reaction to dietary gluten and primarily affects the small intestine. Genetically predisposed individuals develop a chronic inflammatory state of the small intestine which leads to malabsorption. The disease is mediated by HLA DQ2 or DQ8 haplotypes, which bind the gliadin peptides of gluten, present the peptides to CD4+ T lymphocytes and trigger cytokine and B lymphocyte responses.1

The prevalence of CD in the United States is approximately 1% and can reach up to 4-5% in at-risk groups.2 Serologic study of asymptomatic elderly patients in the United Kingdom …

Thyrotoxic Periodic Paralysis – A Case Report Of A Rare Cause Of Paralysis In A 39-Year-Old Asian Man, R. Benson Jones, Md, James Uricheck, Md

The Medicine Forum

Introduction

Uncontrolled hyper thyroidism has a myriad of presentations. Classically, symptoms include weight loss, tremor, palpitations, shortness of breath, diarrhea, anxiety, and heat intolerance. A rare manifestation of hyperthyroidism is thyrotoxic periodic paralysis (TPP). Periodic paralysis is a musculoskeletal channelopathy manifested by episodes of painless muscle weakness often precipitated by heavy exercise, fasting, or high carbohydrate meals. Although classically associated with painless weakness; cramping, myalgias, and stiffness can also occur prior to the episodes as prodromal symptoms. Neurologic examination during an attack typically demonstrates proximal more than distal muscle weakness, and the upper extremities are more commonly affected than the …
