Human Islet Response To Selected Type 1 Diabetes-Associated Bacteria: A Transcriptome-Based Study, Ahmed M. Abdellatif, Heather Jensen Smith, Robert Z. Harms, Nora Sarvetnick

Journal Articles: Eppley Institute

Type 1 diabetes (T1D) is a chronic autoimmune disease that results from destruction of pancreatic β-cells. T1D subjects were recently shown to harbor distinct intestinal microbiome profiles. Based on these findings, the role of gut bacteria in T1D is being intensively investigated. The mechanism connecting intestinal microbial homeostasis with the development of T1D is unknown. Specific gut bacteria such as Bacteroides dorei (BD) and Ruminococcus gnavus (RG) show markedly increased abundance prior to the development of autoimmunity. One hypothesis is that these bacteria might traverse the damaged gut barrier, and their constituents elicit a response from human islets that causes …

Faculty Publications

Background

Antenatal care may be a means to reduce food insecurity in pregnancy and postpartum periods.

Objective

With the use of a cluster-randomized design, we tested whether participation in nutrition-focused antenatal care intending to improve household knowledge about the importance of nutrition for pregnant and lactating women and encourage allocation of household resources to ensure sufficient quality and quantity of foods, without providing food assistance, would reduce household food insecurity.

Methods

Alive & Thrive integrated nutrition interventions into an existing Maternal, Neonatal, and Child Health (MNCH) program in Bangladesh. The nutrition-focused MNCH package was delivered in 10 subdistricts through antenatal …

Comparative Effectiveness Of Dimethyl Fumarate Versus Fingolimod And Teriflunomide Among Ms Patients Switching From First-Generation Platform Therapies In The Us., Daniel Ontaneda, Jacqueline Nicholas, Matthew Carraro, Jia Zhou, Qiang Hou, Jaanai Babb, Katherine Riester, Jason P Mendoza, Terrie Livingston, Mehul Jhaveri

Neuroscience Articles

BACKGROUND: Previous real-world comparative research of MS disease modifying therapies (DMTs) in the overall population has suggested dimethyl fumarate (DMF) to be comparable to fingolimod (FTY) and more efficacious than teriflunomide (TERI) in reducing relapses. However, there is limited comparative evidence in patients switching from platform DMTs in the US. The objective of the study was to compare the annualized relapse rate (ARR) and risk of relapse in MS patients who have switched from a platform therapy to DMF, FTY, or TERI.

METHODS: MS patients (18-65 years old) initiating an oral DMT from June 2013 to March 2015 were identified …

Biological Sciences Faculty Publications

Background

Despite decades of use of control programs, schistosomiasis remains a global public health problem. To further reduce prevalence and intensity of infection, or to achieve the goal of elimination in low-endemic areas, there needs to be better diagnostic tools to detect low-intensity infections in low-endemic areas in Brazil. The rationale for development of new diagnostic tools is that the current standard test Kato-Katz (KK) is not sensitive enough to detect low-intensity infections in low-endemic areas. In order to develop new diagnostic tools, we employed a proteomics approach to identify biomarkers associated with schistosome-specific immune responses in hopes of developing …

Faculty & Staff Scholarship

Background

Dental caries is the most common chronic disease in the US and disproportionately affects racial/ethnic minorities. Caries is heritable, and though genetic heterogeneity exists between ancestries for a substantial portion of loci associated with complex disease, a genome-wide association study (GWAS) of caries specifically in African Americans has not been performed previously.

Methods

We performed exploratory GWAS of dental caries in 109 African American adults (age > 18) and 96 children (age 3–12) from the Center for Oral Health Research in Appalachia (COHRA1 cohort). Caries phenotypes (DMFS, DMFT, dft, and dfs indices) assessed by dental exams were tested for association …

Strategies For Patient Engagement In A Self-Management Program For Adults With Diabetes, Carolinee Jokotola Ogungbayi

Walden Dissertations and Doctoral Studies

Patients' lack of adherence to diabetes self-management education and support (DSMES) recommendations is a challenge for healthcare. One approach to addressing patient noncompliance with DSMES is through education of staff on current guidelines. In an outpatient facility in South Texas, staff training on current DSMES guidelines was recommended as one of the solutions to the problem of Type 2 diabetes mellitus (T2DM) complications observed among clinic patients. An educational module was created to increase staff knowledge on T2DM and to assist staff members in teaching patients to self-manage T2DM. The module was built on the self-management and health promotion models, …

What Predicts Regression From Pre-Diabetes To Normal Glucose Regulation Following A Primary Care Nurse-Delivered Dietary Intervention? A Study Protocol For A Prospective Cohort Study, Kirsten Coppell, Trish Freer, Sally Abel, Lisa Whitehead, David Tipene-Leach, Andrew R. Gray, Tony Merriman, Trudy Sullivan, Jeremy Krebs, Leigh Perreault

Research outputs 2014 to 2021

Introduction Pre-diabetes is a high-risk state for the development of type 2 diabetes mellitus (T2DM) and cardiovascular disease. Regression to normoglycaemia, even if transient, significantly reduces the risk of developing T2DM. The primary aim of this mixed-methods study is to determine if there are clinically relevant differences among those with pre-diabetes and excess weight who regress to normoglycaemia, those who have persistent pre-diabetes and those who progress to T2DM following participation in a 6-month primary care nurse-delivered pre-diabetes dietary intervention. Incidence of T2DM at 2 years will be examined.

Methods and analysis Four hundred participants with pre-diabetes (New Zealand definition …

Manuscripts, Articles, Book Chapters and Other Papers

Allogeneic haematopoietic stem cell transplantation currently represents the primary potentially curative treatment for cancers of the blood and bone marrow. While relapse occurs in approximately 30% of patients, few risk-modifying genetic variants have been identified. The present study evaluates the predictive potential of patient genetics on relapse risk in a genome-wide manner. We studied 151 graft recipients with HLA-matched sibling donors by sequencing the whole-exome, active immunoregulatory regions, and the full MHC region. To assess the predictive capability and contributions of SNPs and INDELs, we employed machine learning and a feature selection approach in a cross-validation framework to discover the …

Fitzgerald, Grant W. Waterer, Catherine A. Read, Edward T. Fysh, Ranjan Shrestha, Christopher Stanley, Sanjeevan Muruganandan, Norris S. H. Lan, Natalia D. Popowicz, Carolyn J. Peddle-Mcintyre, Najib M. Rahman, Seng Khee Gan, Kevin Murray, Yun Chor Gary Lee

Research outputs 2014 to 2021

BACKGROUND: Community-acquired pneumonia (CAP) is a major global disease. Parapneumonic effusions often complicate CAP and range from uninfected (simple) to infected (complicated) parapneumonic effusions and empyema (pus). CAP patients who have a pleural effusion at presentation are more likely to require hospitalization, have a longer length of stay and higher mortality than those without an effusion. Conventional management of pleural infection, with antibiotics and chest tube drainage, fails in about 30% of cases. Several randomized controlled trials (RCT) have evaluated the use of corticosteroids in CAP and demonstrated some potential benefits. Importantly, steroid use in pneumonia has an acceptable safety …

Research outputs 2014 to 2021

Background: Flavonoids, compounds found in plant-based foods and beverages, might ameliorate vascular damage and atherosclerosis. Therefore, our aim was to assess the association between flavonoid intake and hospital admissions due to atherosclerotic cardiovascular disease. Methods: In this prospective cohort study, participants from the Danish Diet, Cancer, and Health Study were cross-linked with Danish nationwide registries. Eligible participants were aged 50–65 years, had no previous history of atherosclerotic cardiovascular disease, and had completed a food-frequency questionnaire at baseline. We examined associations between flavonoid intake (calculated from food-frequency questionnaires with use of the Phenol-Explorer database) and hospital admissions for atherosclerotic cardiovascular disease, …

Recent Climate-Driven Ecological Change Across A Continent As Perceived Through Local Ecological Knowledge, Suzanne M. Prober, Nat Raisbeck-Brown, Natasha B. Porter, Kristen J. Williams, Zoe Leviston, Fiona Dickson

Research outputs 2014 to 2021

Documenting effects of climate change is an important step towards designing mitigation and adaptation responses. Impacts of climate change on terrestrial biodiversity and ecosystems have been well-documented in the Northern Hemisphere, but long-term data to detect change in the Southern Hemisphere are limited, and some types of change are generally difficult to measure. Here we present a novel approach using local ecological knowledge to facilitate a continent-scale view of climate change impacts on terrestrial biodiversity and ecosystems that people have perceived in Australia. We sought local knowledge using a national web-based survey, targeting respondents with close links to the environment …

Sport Medicine In The Prevention And Management Of Cancer, Hao Luo, Daniel A. Galvão, Robert U. Newton, Ciaran M. Fairman, Dennis R. Taaffe

Research outputs 2014 to 2021

Physical inactivity is a major concern in cancer patients despite the established preventative and therapeutic effects of regular physical exercise for this patient group. Sport not only plays an important role in supporting the development and maintenance of a physically active lifestyle but also is increasingly used as a health promotion activity in various populations. Nevertheless, the potential of sport as an effective strategy in the prevention and management of cancer has gained little attention. Based on the scant evidence to date, participation of cancer patients in supervised, well-tailored sport programs appears to be safe and feasible and is associated …

Hiv Viral Rebound Due To A Possible Drug-Drug Interaction Between Elvitegravir/Cobicistat/Emtricitabine/Tenofovir Alafenamide And Calcium-Containing Products: Report Of 2 Cases, S. Lena Kang-Birken, Dena El-Sayed, John Prichard

School of Pharmacy Faculty Articles

Elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (E/C/F/TAF) is a potent fixed-dose, once-daily regimen for HIV-1 treatment and has rare emergence of drug resistance. We report a potential drug-drug interaction in 2 female patients both receiving treatment for HIV and cerebral toxoplasmosis: one case between E/C/F/TAF with calcium carbonate and a second case involving leucovorin as calcium salt. Both cases resulted in rise in HIV RNA levels and emergence of M184 V mutation and resistance to elvitegravir and raltegravir. To the best of our knowledge, these 2 cases are the first reports of rapid emergence of mutation from coadministration of E/C/F/TAF and calcium.

The Divergent Effects Of Cdppb And Cannabidiol On Fear Extinction And Anxiety In A Predator Scent Stress Model Of Ptsd In Rats, John Shallcross, Peter Hámor, Allison R. Bechard, Madison Romano, Lori Knackstedt, Marek Schwendt

Psychology

Post-traumatic stress disorder (PTSD) currently has no FDA-approved treatments that reduce symptoms in the majority of patients. The ability to extinguish fear memory associations is impaired in PTSD individuals. As such, the development of extinction-enhancing pharmacological agents to be used in combination with exposure therapies may benefit the treatment of PTSD. Both mGlu5 and CB1 receptors have been implicated in contextual fear extinction. Thus, here we tested the ability of the mGlu5 positive allosteric modulator 3-Cyano-N-(1,3-diphenyl-1H-pyrazol-5-yl)benzamide (CDPPB) and cannabidiol (CBD) to reduce both conditioned and unconditioned fear. We used a predator-threat animal model of PTSD which we and others have …

The Paradox Of Patient Consent: A Feminist Perspective Of Illness And Healthcare, Kristen Cole

Faculty Publications

Through autoethnographic analysis, I present my personal illness story as a case study in patient consent. In doing so, I explore the complexities that emerge at the intersection of gender and health, including issues of autonomy and choice. Specifically, I reflect on the ideological and systemic factors that contribute to a paradox of consent versus noncompliance in US healthcare contexts. Within this paradoxical binary, control is both persistent and illusive, which is a condition fueled by individualism, paternalistic antagonism, and medical colonization. As an alternative, I offer two viable options for facilitating patients’ agency in gendered health contexts, even under …

Journal Articles: Biostatistics

Nutritional status is a well-recognized prognostic indicator in chronic obstructive pulmonary disease (COPD); however, very little is known about the relationship between lung function and saturated fat intake. We used data from the cross-sectional National Health and Nutrition Examination Surveys (NHANES) to assess the relationship between saturated fatty acid (SFA) intake and lung function in the general US adult population. Adults in NHANES (2007⁻2012) with pre-bronchodilator spirometry measurements and dietary SFA intake were included. Primary outcomes were lung function including forced expiratory volume in one second (FEV₁)

Staff and Researcher Publications

The habenula is a small midbrain structure that is important for brain signaling and learning from negative events. Thus, the habenula is strongly connected to both the reward system and motor regions. Increasing evidence suggests a role for the habenula in the etiology of psychiatric disorders, including mood and substance use disorders. However, no studies to date have investigated habenular resting-state functional connectivity (rsFC) in suicide-related behaviors (SB). The authors enrolled 123 individuals with major depressive disorder (MDD) or bipolar disorder and a history of suicide-related behaviors (SB+), 74 individuals with MDD or bipolar disorder and a history of suicidal …
