Non-Opioid Pharmacologic Agents In The Treatment Of Non-Cancer Chronic Pain In The Outpatient Setting, Diane Eannotti

DNP Projects

Opioid prescription related overdose deaths have increased substantially with evidence demonstrating only modest short-term benefits in chronic pain and thus represents the need to identify alternative treatments to opioids. A needs assessment performed for a federally qualified community health center revealed patients presently taking non-opioid pharmacologic agents in the treatment of chronic non-cancer pain (CNCP) needed additional education in managing multiple non-opioid medications. A targeted approach at improving patient experience and population health supporting the quadruple aim was undertaken with this project.

Purpose: The purpose of this quality improvement project consisted of performing medication management visits for 28 referred patients …

2022 Celebration of Scholarly Works

The purpose of this research was to identify the psycho-emotional needs of family-caregivers of individuals who sustained a traumatic brain injury (TBI), and measure if there was a change in knowledge among occupational therapists, and occupational therapy students following a two-hour seminar covering topics identified in the literature. The topics covered in the seminar included the concept of ambiguous loss, the importance of validating emotions, the caregiver grieving process, and the importance of providing caregiver resources. To measure the change in knowledge, researchers utilized primarily a quantitative research design using pre- and post-test questionnaires with Likert- scale questions. The questionnaire …

Oxygen Deprivation Masks For Training, Brittany M. Hanlon

Student Publications

Oxygen deprivation masks are being advertised towards athletes as a piece of fitness equipment that can simulate the effects of high altitude, as well as a respiratory muscle training device. Studies that investigated the claims as to whether ODMs increased VO2max and improved endurance were looked into. Experimental data did not find that the use of these masks increased VO2max, nor was there any supporting data to prove that it improved endurance. The function of ODMs as a training tool to increase respiratory muscle strength was also examined. There were contradicting results between the three different studies examined. One study …

Prenatal Drug Exposure And Its Effects On Fetal Development: Clinical And Health Education Implications, Johanna Marie Olo Tapangan

Senior Honors Theses

Prenatal drug exposure is a common clinical phenomenon in pregnancy cases. Pregnancy is a fragile period of time for both the mother and the fetus. Therefore, strict drug regulation is important to ensure the safety and wellbeing of the developing fetus. Certain drugs, once thought to be safe, have been found to have detrimental effects on the normal development of functioning organ systems in the fetus. Current research has identified drugs that when taken during pregnancy can result in the onset of fetal physical abnormalities, impaired brain development, and disrupted organogenesis and organ function. Thalidomide, losartan, opioids, alcohol, and caffeine …

T Cell Therapy: Underlying Mechanisms And Current Advancements, Griffin Mccloy

Senior Honors Theses

As the second leading cause of death in 2016, cancer is one of the most serious diseases facing the world today. T cell therapy is a current area of research attempting to address the disease with two primary division: CAR-T and TCR-T cell therapy. The immune system naturally produces T lymphocytes to aid in the recognition and removal of cells infected with viruses or transformed into cancer. Under normal circumstances, T lymphocytes identify and destroy cancerous cells; however, some cancerous cell types can evade this system. With the use of genetic editing technology, T lymphocytes can gain the ability to …

Each cohort conducted de novo harmonized analyses using a prespecified protocol, and findings were pooled using …

Identification Of Genetic Loci Simultaneously Associated With Multiple Cardiometabolic Traits, Alexis C Wood, Amit Arora, Michelle Newell, Victoria L Bland, Jin Zhou, Nicola Pirastu, Jose M Ordovas, Yann C Klimentidis

Children’s Nutrition Research Center Staff Publications

Background and aims: Cardiometabolic disorders (CMD) arise from a constellation of features such as increased adiposity, hyperlipidemia, hypertension and compromised glucose control. Many genetic loci have shown associations with individual CMD-related traits, but no investigations have focused on simultaneously identifying loci showing associations across all domains. We therefore sought to identify loci associated with risk across seven continuous CMD-related traits.

Methods and results: We conducted separate genome-wide association studies (GWAS) for systolic and diastolic blood pressure (SBP/DBP), hemoglobin A1c (HbA1c), low- and high- density lipoprotein cholesterol (LDL-C/HDL-C), waist-to-hip-ratio (WHR), and triglycerides (TGs) in the UK Biobank (N = 356,574-456,823). Multiple …

Β-Carotene Oxygenase 2 Genotype Modulates The Impact Of Dietary Lycopene On Gene Expression During Early Tramp Prostate Carcinogenesis, Nancy E Moran, Jennifer M Thomas-Ahner, Joshua W Smith, Ceasar Silva, Noor A Hason, John W Erdman, Steven K Clinton

Children’s Nutrition Research Center Staff Publications

Background: Epidemiologic studies suggest lycopene and tomato intake are inversely associated with human prostate cancer incidence. In the genetically driven murine prostate carcinogenesis model transgenic adenocarcinoma of the mouse prostate (TRAMP), prostate cancer is inhibited by feeding of lycopene or tomatoes, and these effects are modulated by the β-carotene oxygenase 2 (Bco2) genotype.

Objective: We sought insight into this interaction through evaluation of prostate gene expression patterns during early TRAMP carcinogenesis.

Methods: Three-week-old TRAMP/+ or TRAMP/- × Bco2+/+ or Bco2-/- mice were fed a control, lycopene beadlet, or 10% tomato powder-containing semipurified diet (providing 0, 384 and 462 mg lycopene/kg …

Metabolic Inflexibility In Youth With Obesity: Is It A Feature Of Obesity Or Distinctive Of Youth Who Are Metabolically Unhealthy?, Nour Y Gebara, Joon Young Kim, Fida Bacha, Sojung Lee, Silva Arslanian

Children’s Nutrition Research Center Staff Publications

Background:

Individuals with obesity have metabolic inflexibility with diminished fasting fat oxidation and blunted increase in respiratory quotient (RQ) in insulin-stimulated states. However, it is unclear if metabolic inflexibility is a characteristic of obesity per se or is unique to youth who have metabolically unhealthy obesity (MUO) compared with metabolically healthy obesity (MHO).

Objective:

We investigated metabolic flexibility in youth with MUO, MHO and normal weight (NW) and compared their metabolic characteristics.

Patients/Design:

Youth (n=188) were divided, based on cut-off points for in vivo insulin sensitivity (IS) of adolescents with NW, into 137 with MUO and 51 with MHO. Fasting …

Enzymatic Characterization Of Mrna Cap Adenosine-N6 Methyltransferase Pcif1 Activity On Uncapped Rnas, Dan Yu, Nan Dai, Eric J Wolf, Ivan R Corrêa, Jujun Zhou, Tao Wu, Robert M Blumenthal, Xing Zhang, Xiaodong Cheng

Faculty, Staff and Student Publications

The phosphorylated RNA polymerase II CTD interacting factor 1 (PCIF1) is a methyltransferase that adds a methyl group to the N6-position of 2′O-methyladenosine (Am), generating N6, 2′O-dimethyladenosine (m6Am) when Am is the cap-proximal nucleotide. In addition, PCIF1 has ancillary methylation activities on internal adenosines (both A and Am), although with much lower catalytic efficiency relative to that of its preferred cap substrate. The PCIF1 preference for 2′O-methylated Am over unmodified A nucleosides is due mainly to increased binding affinity for Am. Importantly, it was recently reported that PCIF1 can methylate viral RNA. Although some viral RNA can be translated in …

Classification of myeloid neoplasms with isolated isochromosome i(17q) [17p deletion with inherent monoallelic TP53 loss plus 17q duplication] is controversial. Most cases fall within the WHO unclassifiable myelodysplastic/myeloproliferative neoplasms (MDS/MPN-U) category. The uniformly dismal outcomes warrant better understanding of this entity. We undertook a multi-institutional retrospective study of 92 adult MDS/MPN-U cases from eight institutions. Twenty-nine (32%) patients had isolated i(17q) [MDS/MPN-i(17q)]. Compared to MDS/MPN without i(17q), MDS/MPN-i(17q) patients were significantly younger, had lower platelet and absolute neutrophil counts, and higher frequency of splenomegaly and circulating blasts. MDS/MPN-i(17q) cases showed frequent bilobed neutrophils (75% vs. 23%; P = 0.03), hypolobated …

Pgc1Α/Β Expression Predicts Therapeutic Response To Oxidative Phosphorylation Inhibition In Ovarian Cancer, Carmen Ghilardi, Catarina Moreira-Barbosa, Laura Brunelli, Paola Ostano, Nicolò Panini, Monica Lupi, Alessia Anastasia, Fabio Fiordaliso, Monica Salio, Laura Formenti, Massimo Russo, Edoardo Arrigoni, Ferdinando Chiaradonna, Giovanna Chiorino, Giulio Draetta, Joseph R Marszalek, Christopher P Vellano, Roberta Pastorelli, Mariarosa Bani, Alessandra Decio, Raffaella Giavazzi

Ovarian cancer is the deadliest gynecologic cancer, and novel therapeutic options are crucial to improve overall survival. Here we provide evidence that impairment of oxidative phosphorylation (OXPHOS) can help control ovarian cancer progression, and this benefit correlates with expression of the two mitochondrial master regulators PGC1α and PGC1β. In orthotopic patient-derived ovarian cancer xenografts (OC-PDX), concomitant high expression of PGC1α and PGC1β (PGC1α/β) fostered a unique transcriptional signature, leading to increased mitochondrial abundance, enhanced tricarboxylic acid cycling, and elevated cellular respiration that ultimately conferred vulnerability to OXPHOS inhibition. Treatment with the respiratory chain complex I inhibitor IACS-010759 caused mitochondrial swelling …

Camk2/Camkii Activates Mlkl In Short-Term Starvation To Facilitate Autophagic Flux, Qionghui Zhan, Jaepyo Jeon, Ying Li, Yu Huang, Jian Xiong, Qiaochu Wang, Tian-Le Xu, Yong Li, Fu-Hai Ji, Guangwei Du, Michael X Zhu

Faculty, Staff and Student Publications

MLKL (mixed lineage kinase domain like pseudokinase) is a well-known core component of necrosome that executes necroptotic cell death upon phosphorylation by RIPK3 (receptor interacting serine/threonine kinase 3). Recent studies also implicate a role of MLKL in endosomal trafficking, which is not always dependent on RIPK3. Using mouse Neuro-2a and L929 as well as human HEK293 and HT29 cells, we show here that MLKL is phosphorylated in response to serum and amino acid deprivation from the culture medium, in a manner that depends on CAMK2/CaMKII (calcium/calmodulin dependent protein kinase II) but not RIPK3. The starvation-induced increase in MLKL phosphorylation was …

Alterations Of The Mdm2 C-Terminus Differentially Impact Its Function In Vivo, Vinod Pant, Neeraj K Aryal, Shunbin Xiong, Gilda P Chau, Natalie W Fowlkes, Guillermina Lozano

Faculty, Staff and Student Publications

Murine double minute 2 (Mdm2) is the principal E3-ubiquitin ligase for p53 and contains a C2H2C4 type RING domain wherein the last cysteine residue is followed by an evolutionarily conserved 13 amino acid C-terminal tail. Previous studies have indicated that integrity of the C-terminal tail is critical for Mdm2 function. Recently, a mutation extending the MDM2 length by five amino acids was identified and associated with enhanced p53 response in fibroblasts and premature aging in a human patient. To investigate the importance of the conserved Mdm2 C-terminal length on p53 regulatory function in vivo, we engineered three novel mouse alleles …

Β-Adrenergic Signaling In Skin Cancer, Jennifer Batalla-Covello, Shahrukh Ali, Tongxin Xie, Moran Amit

Faculty, Staff and Student Publications

Activation of the sympathetic nervous system releases catecholamines that can interact with β-adrenergic receptors on tumor cells. Preclinical models have shown that the signaling processes initiated by activation of β-adrenergic receptors increase tumorigenesis, stimulate cell proliferation, and inhibit apoptosis. Indeed, preclinical studies have also shown that β-adrenergic blockade can decrease tumor burden. Researchers have been studying the effects of β-adrenergic receptor blockers on tumor cells and how they may slow the progression of melanoma, basal cell carcinoma, and squamous cell carcinoma. Moreover, clinical data have shown improved prognosis in patients with skin cancer who take β-blockers. This review discusses the …

Faculty, Staff and Student Publications

Tyrosine kinase inhibitors (TKIs) are established drugs in the therapy of FLT3-ITD mutated acute myeloid leukemia (AML). However, acquired mutations, such as D835 in the tyrosine kinase domain (FLT3-ITD/D835), can induce resistance to TKIs. A cap analysis gene expression (CAGE) technology revealed that the gene expression of BCL2A1 transcription start sites was increased in primary AML cells bearing FLT3-ITD/D835 compared to FLT3-ITD. Overexpression of BCL2A1 attenuated the sensitivity to quizartinib, a type II TKI, and venetoclax, a selective BCL2 inhibitor, in AML cell lines. However, a type I TKI, gilteritinib, inhibited the expression of BCL2A1 through inactivation of STAT5 and …

Faculty, Staff and Student Publications

Protein arginine methyltransferases (PRMT) are a widely expressed class of enzymes responsible for catalyzing arginine methylation on numerous protein substrates. Among them, type I PRMTs are responsible for generating asymmetric dimethylarginine. By controlling multiple basic cellular processes, such as DNA damage responses, transcriptional regulation, and mRNA splicing, type I PRMTs contribute to cancer initiation and progression. A type I PRMT inhibitor, GSK3368715, has been developed and has entered clinical trials for solid and hematologic malignancies. Although type I PRMTs have been reported to play roles in modulating immune cell function, the immunologic role of tumor-intrinsic pathways controlled by type I …

Pan-Methylarginine Antibody Generation Using Peg Linked Gar Motifs As Antigens, Yalong Wang, Maria D Person, Mark T Bedford

Faculty, Staff and Student Publications

Arginine methylation is a prevalent posttranslational modification which is deposited by a family of protein arginine methyltransferases (PRMTs), and is found in three different forms in mammalian cells: monomethylarginine (MMA), asymmetric dimethylarginine (ADMA) and symmetric dimethylarginine (SDMA). Pan-methylarginine antibodies are critical for identifying proteins that are methylated on arginine residues, and are also used for evaluating signaling pathways that modulate this methyltransferase activity. Although good pan-MMA, -ADMA and -SDMA antibodies have been developed over the years, there is still room for improvement. Here we use a novel antigen approach, which involves the separation of short methylated motifs with inert polyethylene …

Effect Of Perfluorocarbon Composition On Activation Of Phase-Changing Ultrasound Contrast Agents, Trevor M Mitcham, Dmitry Nevozhay, Yunyun Chen, Linh D Nguyen, Gianmarco F Pinton, Stephen Y Lai, Konstantin V Sokolov, Richard R Bouchard

Faculty, Staff and Student Publications

BACKGROUND: While microbubble contrast agents (MCAs) are commonly used in ultrasound (US), they are inherently limited to vascular targets due to their size. Alternatively, phase-changing nanodroplet contrast agents (PNCAs) can be delivered as nanoscale agents (i.e., small enough to extravasate), but when exposed to a US field of sufficient mechanical index (MI), they convert to MCAs, which can be visualized with high contrast using nonlinear US.

PURPOSE: To investigate the effect of perfluorocarbon (PFC) core composition and presence of cholesterol in particle coatings on stability and image contrast generated from acoustic activation of PNCAs using high-frequency US suitable for clinical …
