Assessing The Uptake Of Biosimilar Insulin Glargine Among Physicians For The Treatment Of Diabetes In South Africa, Euganthri Pillay

Walden Dissertations and Doctoral Studies

In South Africa, diabetes is a serious problem where 1 in 9 adults has diabetes, making it the country with the highest diabetes prevalence on the African continent. Even though insulin is an absolute necessity for treating diabetes, it is unaffordable to millions. Biosimilar insulins, however, are innovative medicines that are similar but not exact copies of the originator insulin, making alternative treatment affordable to patients. The problem is that, in South Africa, it is still not known whether patients have access to biosimilar insulin in a country where diabetes is rampant. The diffusion of innovation theory was used to …

Nurturing Care Assets For Food Security: A Community Asset Mapping Approach, Gabriela Buccini, Kaelia Lynn Saniatan, Ana Poblacion, Ana Bauman, Cristina Hernandez, Cali Larrison, Dodds P Simangan, Jyoti Desai, Yvonne Owens Ferguson, Alisa Howard, Melva Thompson-Robinson

2020-Current year OA Pubs

BACKGROUND: Zip codes classified by the Food Insecurity Index with moderate and high food insecurity (FI) risk can be a threat to the health and well-being of children during the first 1,000 days (from pregnancy to 2 years). The presence of nurturing care assets (i.e., stable environments that promote health and nutrition, learning opportunities, security and safety, and responsive relationships) can contribute to supporting families and their communities, and ultimately reduce systemic barriers to food security. We aimed to identify and characterize nurturing care assets in under-resourced communities with moderate and high FI risk.

METHODS: Four steps were used to …

Comparative genomics has revealed the rapid expansion of multiple gene families involved in immunity. Members within each gene family often evolved distinct roles in immunity. However, less is known about the evolution of their epigenome and cis-regulation. Here we systematically profile the epigenome of the recently expanded murine Ly49 gene family that mainly encode either inhibitory or activating surface receptors on natural killer cells. We identify a set of cis-regulatory elements (CREs) for activating Ly49 genes. In addition, we show that in mice, inhibitory and activating Ly49 genes are regulated by two separate sets of proximal CREs, likely resulting from …

Small Molecule Therapeutics In The Pipeline Targeting For Triple-Negative Breast Cancer: Origin, Challenges, Opportunities, And Mechanisms Of Action, Nneoma James, Esther Owusu, Gildardo Rivera-Sanchez, Debasish Bandyopadhyay

School of Integrative Biological & Chemical Sciences Faculty Publications

Triple-negative breast cancer (TNBC) cells are devoid of estrogen receptors (ERs), progesterone receptor (PRs), and human epidermal growth factor receptor 2 (HER2), and it (TNBC) counts for about 10–15% of all breast cancers. TNBC is highly invasive, having a faster growth rate and a higher risk of metastasis and recurrence. Still, chemotherapy is one of the widely used options for treating TNBC. This study reviewed the histological and molecular characterization of TNBC subtypes, signaling pathways that are aberrantly expressed, and small molecules targeting these pathways, as either single agents or in combination with other therapeutic agents like chemotherapeutics, immunotherapeutics, and …

To identify credible causal risk variants (CCVs) associated with different histotypes of epithelial ovarian cancer (EOC), we performed genome-wide association analysis for 470,825 genotyped and 10,163,797 imputed SNPs in 25,981 EOC cases and 105,724 controls of European origin. We identified five histotype-specific EOC risk regions (p value < 5 × 10-8) and confirmed previously reported associations for 27 risk regions. Conditional analyses identified an additional 11 signals independent of the primary signal at six risk regions (p value < 10-5). Fine mapping identified 4,008 CCVs in these regions, of which 1,452 CCVs were located in ovarian cancer-related chromatin marks with significant enrichment in active enhancers, active promoters, and active regions for CCVs from each EOC histotype. Transcriptome-wide association and colocalization analyses across histotypes using tissue-specific and cross-tissue datasets identified 86 candidate susceptibility genes in known EOC risk regions and 32 genes in 23 additional genomic regions that may represent novel EOC risk loci (false discovery rate < 0.05). Finally, by integrating genome-wide HiChIP interactome analysis with transcriptome-wide association study (TWAS), variant effect predictor, transcription factor ChIP-seq, and motifbreakR data, we identified candidate gene-CCV interactions at each locus. This included risk loci where TWAS identified one or more candidate susceptibility genes (e.g., HOXD-AS2, HOXD8, and HOXD3 at 2q31) and other loci where no candidate gene was identified (e.g., MYC and PVT1 at 8q24) by TWAS. In summary, this study describes a functional framework and provides a greater understanding of the biological significance of risk alleles and candidate gene targets at EOC susceptibility loci identified by a genome-wide association study.

Hnrnpm Protects Against The Dsrna-Mediated Interferon Response By Repressing Line-Associated Cryptic Splicing, Rong Zheng, Mikayla Dunlap, Georg O M Bobkov, Carlos Gonzalez-Figueroa, Khushali J Patel, Jingyi Lyu, Samuel E Harvey, Tracey W Chan, Giovanni Quinones-Valdez, Mudra Choudhury, Charlotte A Le Roux, Mason D Bartels, Amy Vuong, Ryan A Flynn, Howard Y Chang, Eric L Van Nostrand, Xinshu Xiao, Chonghui Cheng

RNA splicing is pivotal in post-transcriptional gene regulation, yet the exponential expansion of intron length in humans poses a challenge for accurate splicing. Here, we identify hnRNPM as an essential RNA-binding protein that suppresses cryptic splicing through binding to deep introns, maintaining human transcriptome integrity. Long interspersed nuclear elements (LINEs) in introns harbor numerous pseudo splice sites. hnRNPM preferentially binds at intronic LINEs to repress pseudo splice site usage for cryptic splicing. Remarkably, cryptic exons can generate long dsRNAs through base-pairing of inverted ALU transposable elements interspersed among LINEs and consequently trigger an interferon response, a well-known antiviral defense mechanism. …

Parietal cells (PCs) produce gastric acid to kill pathogens and aid digestion. Dysregulated PC census is common in disease, yet how PCs differentiate is unclear. Here, we identify the PC progenitors arising from isthmal stem cells, using mouse models and human gastric cells, and show they preferentially express cell-metabolism regulator and orphan nuclear receptor Estrogen-related receptor gamma (Esrrg, encoding ERRγ). Esrrg expression facilitated the tracking of stepwise molecular, cellular, and ultrastructural stages of PC differentiation. Esrrg^P2ACreERT2 lineage tracing revealed Esrrg expression commits progenitors to differentiate into mature PCs. scRNA-seq indicated the earliest Esrrg+ PC progenitors preferentially …

Dna Methylation And Stroke Prognosis: An Epigenome-Wide Association Study, Joan Jiménez-Balado, Carolina Soriano-Tárraga, Et Al.

2020-Current year OA Pubs

BACKGROUND AND AIMS: Stroke is the leading cause of adult-onset disability. Although clinical factors influence stroke outcome, there is a significant variability among individuals that may be attributed to genetics and epigenetics, including DNA methylation (DNAm). We aimed to study the association between DNAm and stroke prognosis.

METHODS AND RESULTS: To that aim, we conducted a two-phase study (discovery-replication and meta-analysis) in Caucasian patients with ischemic stroke from two independent centers (BasicMar [discovery, N = 316] and St. Pau [replication, N = 92]). Functional outcome was assessed using the modified Rankin Scale (mRS) at three months after stroke, being poor …

School of Medicine Faculty Publications

Background: A phase 3b, open-label, multicenter, expanded-access study (NCT04123548) evaluated safety and clinical outcomes of StrataGraft treatment in adults with deep partial-thickness thermal burns with intact dermal elements. Methods: Adult patients with 3 % to < 50 % total body surface area burns were treated with a single application of ≤ 1:1 meshed StrataGraft and followed for 24 weeks. Primary endpoint was count and percentage of patients with treatment-emergent adverse events (TEAEs). Secondary endpoints included confirmed wound closure (WC) at Week 12, durable WC at Week 24, time to WC, scar evaluation, and wound infection-related events. Results: Fifty-two patients with 96 treatment sites were enrolled. Pruritus was the most common TEAE (22 patients [42.3 %]). Twenty serious TEAEs occurred in 10 patients (19.2 %); none were related to StrataGraft. There were 4 (7.7 %) deaths (aspiration, myocardial infarction, self-injury, Gram-negative rod sepsis); none were related to StrataGraft. Confirmed WC was achieved by Week 12 in 33 patients (63.5 %; 95 % CI: 50.4–76.5 %) and 69 treatment sites (71.9 %; 95 % CI: 62.9–80.9 %). Durable WC was achieved by Week 24 in 29 patients (55.8 %; 95 % CI: 42.3–69.3 %) and 58 treatment sites (60.4 %; 95 % CI: 50.6–70.2 %). Conclusions: StrataGraft demonstrated clinical benefit. Safety data were consistent with previously reported findings.

Counselor Education Faculty Publications and Presentations

Background: Rheumatoid arthritis (RA) is a chronic disease and may worsen over time. Today, nurse-led case management (NLCM) has been recommended to improve clinical outcomes for chronic disease patients, yet little is known regarding its impact on pain, fatigue, and C-reactive protein (CRP) among RA patients. We aimed to explore this issue among such groups via a two-group pre- and post-test approach.

Methods: All subjects were recruited from one hospital in Taiwan from January 2017 to June 2018 and assigned to either a 6-month NLCM program in addition to usual care or to a control group that received usual care …

Hemoglobin A1c Values In Patients With Two Types Of Insurance, Patricia Ann White

Walden Dissertations and Doctoral Studies

Diabetes is the seventh leading cause of death for adults in the United States. Evidence suggests that not all patients receive the same level of care and discrepancies may be based on the type of health care coverage they have. Providers use Hemoglobin A1C (A1C) as the primary test to indicate treatment success for persons with diabetes. Providers may be ordering this critical lab value differently based on the patient’s insurance plan. In this project, A1C levels in diabetic patients receiving managed care versus traditional Medicare were evaluated. It is important to understand if potential disparities in care exist. The …

Efforts on developing transient receptor potential vanilloid 1 (TRPV1) drugs for pain management have been hampered by deleterious hypo- or hyperthermia caused by TRPV1 agonists/antagonists. Here, we compared the effects of four antagonists on TRPV1 polymodal gating and core body temperature (CBT) in Trpv1+/+, Trpv1-/-, and Trpv1T634A/T634A. Neither the effect on proton gating nor drug administration route, hair coverage, CBT rhythmic fluctuations, or inflammation had any influence on the differential actions of TRPV1 drugs on CBT. We identified the S4-S5 linker region exposed to the vanilloid pocket of TRPV1 to be critical for hyperthermia associated with certain TRPV1 antagonists. PSFL2874, …

Perturbations In Risk/Reward Decision Making And Frontal Cortical Catecholamine Regulation Induced By Mild Traumatic Brain Injury, Christopher P Knapp, Eleni Papadopoulos, Jessica A Loweth, Ramesh Raghupathi, Stan B Floresco, Barry D Waterhouse, Rachel L Navarra

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Mild traumatic brain injury (mTBI) disrupts cognitive processes that influence risk taking behavior. Little is known regarding the effects of repetitive mild injury (rmTBI) or whether these outcomes are sex specific. Risk/reward decision making is mediated by the prefrontal cortex (PFC), which is densely innervated by catecholaminergic fibers. Aberrant PFC catecholamine activity has been documented following TBI and may underlie TBI-induced risky behavior. The present study characterized the effects of rmTBI on risk/reward decision making behavior and catecholamine transmitter regulatory proteins within the PFC. Rats were exposed to sham, single (smTBI), or three closed-head controlled cortical impact (CH-CCI) injuries and …

UNLABELLED: The PI3K pathway regulates essential cellular functions and promotes chemotherapy resistance. Activation of PI3K pathway signaling is commonly observed in triple-negative breast cancer (TNBC). However previous studies that combined PI3K pathway inhibitors with taxane regimens have yielded inconsistent results. We therefore set out to examine whether the combination of copanlisib, a clinical grade pan-PI3K inhibitor, and eribulin, an antimitotic chemotherapy approved for taxane-resistant metastatic breast cancer, improves the antitumor effect in TNBC. A panel of eight TNBC patient-derived xenograft (PDX) models was tested for tumor growth response to copanlisib and eribulin, alone or in combination. Treatment-induced signaling changes were …

Tl1a And Il-18 Synergy Promotes Gm-Csf-Dependent Thymic Granulopoiesis In Mice, Mario Ruiz Pérez, Kodi Ravichandran, Et Al.

2020-Current year OA Pubs

Acute systemic inflammation critically alters the function of the immune system, often promoting myelopoiesis at the expense of lymphopoiesis. In the thymus, systemic inflammation results in acute thymic atrophy and, consequently, impaired T-lymphopoiesis. The mechanism by which systemic inflammation impacts the thymus beyond suppressing T-cell development is still unclear. Here, we describe how the synergism between TL1A and IL-18 suppresses T-lymphopoiesis to promote thymic myelopoiesis. The protein levels of these two cytokines were elevated in the thymus during viral-induced thymus atrophy infection with murine cytomegalovirus (MCMV) or pneumonia virus of mice (PVM). In vivo administration of TL1A and IL-18 induced …

Shea Position Statement On Pandemic Preparedness For Policymakers: Building A Strong And Resilient Healthcare Workforce, Robin L.P. Jump

Faculty Scholarship

Throughout the COVID-19 pandemic, many areas in the United States experienced healthcare personnel (HCP) shortages tied to a variety of factors. Infection prevention programs, in particular, faced increasing workload demands with little opportunity to delegate tasks to others without specific infectious diseases or infection control expertise. Shortages of clinicians providing inpatient care to critically ill patients during the early phase of the pandemic were multifactorial, largely attributed to increasing demands on hospitals to provide care to patients hospitalized with COVID-19 and furloughs.¹ HCP shortages and challenges during later surges, including the Omicron variant-associated surges, were largely attributed to HCP …

Shea Position Statement On Pandemic Preparedness For Policymakers: Introduction And Overview, Robin L.P. Jump
