Introduction: Clinician time and resources may be underutilised if the treatment they offer does not match patient expectations and attitudes. We developed a questionnaire (AxEL-Q) to guide clinicians toward elements of first-line care that are pertinent to their patients with low back pain. Methods: We used guidance from the COSMIN consortium to develop the questionnaire and evaluated it in a sample of people with low back pain of any duration. Participants were recruited from the community, were over 18 years and fluent in English. Statements that represented first-line care were identified. Semantic scales were used to measure attitude towards these …

Bilateral Sequential Theta Burst Stimulation In Depressed Veterans With Service Related Posttraumatic Stress Disorder: A Feasibility Study, Thelepa Vaithianathan, Mervin Blair, Vanessa Soares, Yuri E. Rybak, Lena Palaniyappan, J. Don Richardson, Amer M. Burhan

Neuroscience Institute Publications

Background: Depression comorbid with posttraumatic stress disorder (PTSD) can be disabling and treatment resistant. Preliminary evidence suggests that repetitive transcranial magnetic stimulation (rTMS), may have a role in helping these patients. There are only few published studies using different rTMS paradigms including bilateral intermittent theta burst (iTBS) and low frequency rTMS. Methods: In this small cohort observation study, we examined the efficacy of bilateral sequential theta-burst stimulation (bsTBS) in 8 treatment resistant depression (TRD) military veterans with PTSD comorbidity stemming from military service experience. Results: bsTBS was generally well tolerated and resulted in 25% and 38% remission and response rates …

Changing collective behaviour and supporting non-pharmaceutical interventions is an important component in mitigating virus transmission during a pandemic. In a large international collaboration (Study 1, N = 49,968 across 67 countries), we investigated self-reported factors associated with public health behaviours (e.g., spatial distancing and stricter hygiene) and endorsed public policy interventions (e.g., closing bars and restaurants) during the early stage of the COVID-19 pandemic (April-May 2020). Respondents who reported identifying more strongly with their nation consistently reported greater engagement in public health behaviours and support for public health policies. Results were similar for representative and non-representative national samples. Study 2 …

Elevated Vascular Transformation Blood Biomarkers In Long-Covid Indicate Angiogenesis As A Key Pathophysiological Mechanism, Maitray A. Patel, Michael J. Knauer, Michael Nicholson, Mark Daley, Logan R. Van Nynatten, Claudio Martin, Eric K. Patterson, Gediminas Cepinskas, Shannon L. Seney, Verena Dobretzberger, Markus Miholits, Brian Webb, Douglas D. Fraser

Neuroscience Institute Publications

Background: Long-COVID is characterized by prolonged, diffuse symptoms months after acute COVID-19. Accurate diagnosis and targeted therapies for Long-COVID are lacking. We investigated vascular transformation biomarkers in Long-COVID patients. Methods: A case–control study utilizing Long-COVID patients, one to six months (median 98.5 days) post-infection, with multiplex immunoassay measurement of sixteen blood biomarkers of vascular transformation, including ANG-1, P-SEL, MMP-1, VE-Cad, Syn-1, Endoglin, PECAM-1, VEGF-A, ICAM-1, VLA-4, E-SEL, thrombomodulin, VEGF-R2, VEGF-R3, VCAM-1 and VEGF-D. Results: Fourteen vasculature transformation blood biomarkers were significantly elevated in Long-COVID outpatients, versus acutely ill COVID-19 inpatients and healthy controls subjects (P < 0.05). A unique two biomarker profile consisting of ANG-1/P-SEL was developed with machine learning, providing a classification accuracy for Long-COVID status of 96%. Individually, ANG-1 and P-SEL had excellent sensitivity and specificity for Long-COVID status (AUC = 1.00, P < 0.0001; validated in a secondary cohort). Specific to Long-COVID, ANG-1 levels were associated with female sex and a lack of disease interventions at follow-up (P < 0.05). Conclusions: Long-COVID patients suffer prolonged, diffuse symptoms and poorer health. Vascular transformation blood biomarkers were significantly elevated in Long-COVID, with angiogenesis markers (ANG-1/P-SEL) providing classification accuracy of 96%. Vascular transformation blood biomarkers hold potential for diagnostics, and modulators of angiogenesis may have therapeutic efficacy.

Neuroscience Institute Publications

Background: Neuroinflammation is emerging as an important pathological process in frontotemporal dementia (FTD), but biomarkers are lacking. We aimed to determine the value of complement proteins, which are key components of innate immunity, as biomarkers in cerebrospinal fluid (CSF) and plasma of presymptomatic and symptomatic genetic FTD mutation carriers. Methods: We measured the complement proteins C1q and C3b in CSF by ELISAs in 224 presymptomatic and symptomatic GRN, C9orf72 or MAPT mutation carriers and non-carriers participating in the Genetic Frontotemporal Dementia Initiative (GENFI), a multicentre cohort study. Next, we used multiplex immunoassays to measure a panel of 14 complement proteins …

Rowe, Rik Vandenberghe, Elizabeth Finger, Fabrizio Tagliavini, Isabel Santana, Chris R. Butler, Simon Ducharme, Alexander Gerhard, Adrian Danek, Johannes Levin, Markus Otto

Neuroscience Institute Publications

Background: Approximately a third of frontotemporal dementia (FTD) is genetic with mutations in three genes accounting for most of the inheritance: C9orf72, GRN, and MAPT. Impaired synaptic health is a common mechanism in all three genetic variants, so developing fluid biomarkers of this process could be useful as a readout of cellular dysfunction within therapeutic trials. Methods: A total of 193 cerebrospinal fluid (CSF) samples from the GENetic FTD Initiative including 77 presymptomatic (31 C9orf72, 23 GRN, 23 MAPT) and 55 symptomatic (26 C9orf72, 17 GRN, 12 MAPT) mutation carriers as well as 61 mutation-negative controls were measured using a …

Neuroscience Institute Publications

Background: Clinical endpoints for upcoming therapeutic trials in frontotemporal dementia (FTD) are increasingly urgent. Cognitive composite scores are often used as endpoints but are lacking in genetic FTD. We aimed to create cognitive composite scores for genetic frontotemporal dementia (FTD) as well as recommendations for recruitment and duration in clinical trial design. Methods: A standardized neuropsychological test battery covering six cognitive domains was completed by 69 C9orf72, 41 GRN, and 28 MAPT mutation carriers with CDR® plus NACC-FTLD ≥ 0.5 and 275 controls. Logistic regression was used to identify the combination of tests that distinguished best between each mutation carrier …

Using Orsim Technology To Educate Anesthesia Providers On Fiberoptic Bronchoscopy: An Objective Structured Clinical Evaluation, Luke Anderson Leblanc, Selby Reed Thames

Doctoral Projects

Fiberoptic bronchoscopy (FB) is an essential skill that has been used for years by healthcare providers for diagnostic and therapeutic interventions. The basic components of a fiberoptic bronchoscope include a light source, fiber optics (thin, flexible fibers with a glass core that light can pass through), and a camera (Qanash et al., 2020). The light source and camera work together to enhance the ability of the healthcare provider to visualize the anatomic and physiologic structures and mechanisms while the fiber optics provide a passageway through which the light source can shine. To enhance the effective use of a fiberoptic bronchoscope …

Blind Spot: Implicit Bias In Health Care And Its Awareness Among Nursing Students At The University Of Southern Mississippi, Debora Skaliks

Doctoral Projects

While prejudice and bias are eminent topics in our society, implicit bias or unconscious bias is not as easily detected. Even though implicit bias may be a familiar concept to many, numerous healthcare workers frequently do not recognize the extent of harm such biases can impose on patients' health and outcomes. The Blind Spot DNP project exposed in this research paper explores the relentless question of the correlation between implicit bias awareness, implicit bias education, and its impact on health care. This Doctor of Nursing Project (DNP) project aimed to analyze whether implicit bias education and testing could increase unconscious …

Where Are We On This Path? Faculty Experiences Working With Guided Pathways, Christopher Tombari

Dissertations

In this research study, 14 faculty from 13 community colleges were interviewed about their experiences working within the guided pathways framework. They described how processes and procedures at their colleges were modified in significant ways after adopting guided pathways. Viewed through the lens of institutional logics, data suggested that multiple logics interacted and framed the individuals’ perceptions of guided pathways and their opinions regarding the resulting changes to practice. Where logics coexisted and demonstrated complementary values, guided pathways was viewed favorably. Guided pathways elicited negative reactions where logics coexisted in conflict. This research has implications for college leadership considering implementing …

Investigating Novice Nurses’ Perceptions Of Academic Dishonesty During Nursing Education, Christy Michelle Gough

Dissertations

Academic dishonesty in nursing education has been an ongoing concern to the nursing profession for many decades. There is a concern that students who engage in academic dishonesty in the classroom setting might also engage in dishonest behaviors in the professional setting. Many studies in the literature explored nursing students’ perceptions of academic dishonesty during nursing education; however, there was limited literature on novice nurses’ perceptions of academic dishonesty and its impact on the nursing profession. Novice nurses provided the voice of recent nursing students as well as the voice of a professional nurse. The purpose of this qualitative study …

An Ultrasensitive Bacterial Detection Platform For Culture-Free Diagnosis Of Infections, Xuyang Shi

ETD Archive

The current methods of the diagnosis of bloodstream infections are based on bacterial culture growth, a process that requires considerable time, e.g., 12-16 hours, to obtain a result. This long wait time for the result creates many problems, including the generation of multi-drug resistant organisms (MDROs). At the same time, infected bloodstream usually contains a very low concentration of bacteria, i.e., lower than 5 CFU/mL. The long diagnosis time and the extremely low concentration of bacteria in the infected bloodstream make such infections difficult to diagnose. Here, we demonstrate a culture-free approach for the diagnosis of bloodstream infections using a …

The Morgue The Merrier? Covid19-Related Threat, Existential Isolation, & Well Being, Lauren P. Sedivy

ETD Archive

Prior research suggests that COVID-19 perceived threat and existential isolation (EI) would be associated with an individual’s subjective health, levels of anxiety, and feelings of hope relating specifically to the COVID-19 pandemic. However, it was unclear whether such concerns might be unique predictors (no interaction, two cumulative main effects) or interact (one effect modifies the other). To learn more about the possible combined effects, I analyzed data gathered via MTurk, during an 11-week period at the height of the COVID-19 pandemic (March-June 2020). Method: This study (N = 2,673) measured perceived COVID19-related threat, EI, anxiety, subjective health, and hope. Results: …

"I Need To Write About What I Believe": Journaling And Afrofuturism In Octavia E. Butler's Parable Of The Sower And Parable Of The Talents, Shlana E. Sims

ETD Archive

Butler’s choice of using the diary of a young Black girl and of making that Black girl a leader is directly paralleled in real history via diaries, such as The Memphis Diary of Ida B. Wells. Butler’s use of the journaling technique via a Black woman ties the future to the past as the diaries of these influential Black women are read by later generations giving a glimpse of what dreams, hopes, and goals the women had for the Black Community. She further gives cautionary tales of “if-this-continues to-go-on” as a warning for the community to be on its guard, …

Biology: Faculty Publications and Other Works

Complex morphological traits are the product of many genes with transient or lasting developmental effects that interact in anatomical context. Mouse models are a key resource for disentangling such effects, because they offer myriad tools for manipulating the genome in a controlled environment. Unfortunately, phenotypic data are often obtained using laboratory-specific protocols, resulting in self-contained datasets that are difficult to relate to one another for larger scale analyses. To enable meta-analyses of morphological variation, particularly in the craniofacial complex and brain, we created MusMorph, a database of standardized mouse morphology data spanning numerous genotypes and developmental stages, including E10.5, E11.5, …

Sleep To Reduce Incident Depression Effectively (Stride): Study Protocol For A Randomized Controlled Trial Comparing Stepped-Care Cognitive-Behavioral Therapy For Insomnia Versus Sleep Education Control To Prevent Major Depression, Christopher L. Drake, David A. Kalmbach, Philip Cheng, Brian K. Ahmedani, Edward L. Peterson, Christine L. M. Joseph, Thomas Roth, Kelley M. Kidwell, Chaewon Sagong

Sleep Medicine Articles

BACKGROUND: Prevention of major depressive disorder (MDD) is a public health priority. Strategies targeting individuals at elevated risk for MDD may guide effective preventive care. Insomnia is a reliable precursor to depression, preceding half of all incident and relapse cases. Thus, insomnia may serve as a useful entry point for preventing MDD. Cognitive-behavioral therapy for insomnia (CBT-I) is recommended as the first-line treatment for insomnia, but widespread implementation is limited by a shortage of trained specialists. Innovative stepped-care approaches rooted in primary care can increase access to CBT-I and reduce rates of MDD.

METHODS/DESIGN: We propose a large-scale stepped-care clinical …

Precision Rehabilitation For Aphasia By Patient Age, Sex, Aphasia Severity, And Time Since Stroke? A Prespecified, Systematic Review-Based, Individual Participant Data, Network, Subgroup Meta-Analysis, Release Collaborators, Jacqueline Hinckley

HPD Articles

BACKGROUND: Stroke rehabilitation interventions are routinely personalized to address individuals' needs, goals, and challenges based on evidence from aggregated randomized controlled trials (RCT) data and meta-syntheses. Individual participant data (IPD) meta-analyses may better inform the development of precision rehabilitation approaches, quantifying treatment responses while adjusting for confounders and reducing ecological bias. AIM: We explored associations between speech and language therapy (SLT) interventions frequency (days/week), intensity (h/week), and dosage (total SLT-hours) and language outcomes for different age, sex, aphasia severity, and chronicity subgroups by undertaking prespecified subgroup network meta-analyses of the RELEASE database. METHODS: MEDLINE, EMBASE, and trial registrations were systematically …

Development And Control Of A Pediatric Lower Limb Exoskeleton For Gait Guidance, Anthony Clarence Goo

ETD Archive

Several genetic, developmental and neurological disorders can cause various levels of gait impairment in the pediatric population. Powered lower limb orthoses, or exoskeletons, have recently been used to address gait impairment and afford therapists alternative solutions and strategies for gait therapy. Most exoskeleton research has focused on the adult population while the pediatric population remains underserved. The limitations of current pediatric exoskeletons make them impractical for use in both community and clinical settings. Furthermore, exoskeleton controllers suitable for these environments should promote human volitional control while guiding the subject towards a dynamically stable healthy gait pattern.

Evaluation Of Biological And Chemical Seed Treatments For Management Of Rice Diseases, Sherif Adam Sharfadine

Graduate Theses and Dissertations

Rice is the primary staple for more than half of the global population and is the second most important cereal worldwide. In the US, rice is primarily grown in the southern states, with Arkansas leading production and responsible for 47% of the total rice production in the country. Diseases cause significant yield losses in rice. Sheath blight, rice blast and bacterial panicle blight are the main diseases in rice and cause significant yield losses. Sheath blight alone could cause up 50% yield loss in heavily damaged fields with highly susceptible cultivars. Additionally, rice seed and seedling diseases primarily caused by …

Evaluating Arkansas Weathering Steel Bridge Performance, Yessenia Gonzalez

Graduate Theses and Dissertations

Weathering steel enhances corrosion-resistant steel features over conventional steel when a patina properly forms on the weathering steel surface. Weathering steel is a low carbon steel of less than 0.3% carbon by weight and has a chemical composition including other alloying elements such as nickel, copper, and chromium that develops a patina. The patina is a dense protective oxide film layer that develops on the steel member surface. The patina defends the steel from corrosion by preventing moisture, oxygen, and contaminant penetration. However, long periods of moisture and deicing chemicals applied during wet wintry conditions hinder proper patina formation. Without …
