Social Inequalities And The Adoption Of Health Misinformation In Cameroon: Implications On Health Behaviour, Eugene Nche Che Sep 2023

Social Inequalities And The Adoption Of Health Misinformation In Cameroon: Implications On Health Behaviour, Eugene Nche Che

Library Philosophy and Practice (e-journal)

Public health restrictions in response to the COVID-19 pandemic resulted in an increase in the reliance on social media for peer interactions. This resulted in the proliferation of medical misinformation and conspiracy theories that undermined public support for disease control measures, and influenced negative health attitudes such as vaccine denial. The aim of this study was to determine how social inequalities influence the adoption of health related misinformation, and the extent to which the adoption of health misinformation results in poor health behaviours. The study employed an exploratory survey design, and relied on both quantitative and qualitative methods to collect …


Pica: The Mysterious Eating Disorder, James Ferrante, Justin Fisher, Tara Sung, Spencer Wenzel Sep 2023

Pica: The Mysterious Eating Disorder, James Ferrante, Justin Fisher, Tara Sung, Spencer Wenzel

Discovery Day

Background. ‘Pica’ is the Latin word for magpie, a bird that ingests inedible substances. The DSM-V defines pica as a disorder of persistent eating of nonnutritive, nonfood substances over a period of at least one month. Although pica is a disorder that affects a widespread population, it is seen as a social anomaly which prevents patients from admitting their behavior. As the behavior continues unnoticed and untreated, patients will experience the adverse effects of ingesting foreign materials. Thus, healthcare providers and family members should educate themselves on pica’s etiologies and manifestations to prevent complications and avoid unnecessary hospitalizations.

Neurofeedback Within The Scope Of Occupational Therapy With Clients With Substance Use Disorder: A Scoping Review, Aundrea Culliver, Mary Ann Smith, Steven M. Gerardi, Colin Ross

Summer 2023 Virtual OTD Capstone Symposium

Substance use disorder (SUD) is a problematic pattern of use of a substance or substances, leading to impairments to health, social function, and control of a substance. This negatively affects everyday activities of daily living, and occupation performance that causes a disruption to physical, mental, and social health.

Now, Neurofeedback is a noninvasive biotherapy that uses audio or video feedback to reinforce healthy brain function. This type of intervention usually works by having a patient listen to music and putting electrodes on a patient’s head that pick up negative or positive brain activity or waves. And if the negative activity …


Mapping Between Cognitive Theories And Psycho-Physiological Models Of Attention System Performance, Oliver A. Guidetti, Craig P. Speelman, Peter Bouhlas Sep 2023

Mapping Between Cognitive Theories And Psycho-Physiological Models Of Attention System Performance, Oliver A. Guidetti, Craig P. Speelman, Peter Bouhlas

Research outputs 2022 to 2026

Declines in the capacity to sustain attention to repetitive, monotonous tasks is a phenomenon known as vigilance decrement (Endsley M, Kiris E. The out-of-the-loop performance problem and level of control in automation. 1995. Hum Factors. 37:32-64). This review compares cognitive theories with psycho-physiological models of vigilance decrement, and a gap is identified in mapping between the 2. That is, theories of vigilance decrement refer to "cognitive" resources; by contrast, psychophysiological models of the cerebral systems associated with attention explain performance functions according to neurochemical resources. A map does not currently exist in the literature that bridges the gap between cognitive …

Theories Of Consciousness And A Life Worth Living, Liad Mudrik, Myrto Mylopoulos, Niccolo Negro, Aaron Schurger Sep 2023

Theories Of Consciousness And A Life Worth Living, Liad Mudrik, Myrto Mylopoulos, Niccolo Negro, Aaron Schurger

Psychology Faculty Articles and Research

What is it that makes a life valuable? A popular view is that life’s moral worth depends in some way on its relationship to consciousness or subjective experience. But a practical application of this view requires the ability to test for consciousness, which is currently lacking. Here, we examine how theories of consciousness (ToCs) can help do so, focusing especially on difficult cases where the answer is not clear (e.g. fetuses, nonhuman animals, unresponsive brain-injured patients, and advanced artificial systems). We consider five major ToCs and what predictions they offer: Integrated information theory, Higher-Order Thought Theory, Recurrent Processing Theory, Global …

The Classification Of Obesity Based On Metabolic Status Redefines The Readmission Of Non-Hodgkin’S Lymphoma—An Observational Study, Eunju Kim, Kazuaki Mawatari, Seung-Hee Yoo, Zheng Chen

Faculty, Staff and Student Publications

Obesity is a known risk factor for metabolic diseases and is often associated with chronic inflammation in adipose tissue. We previously identified the polyethoxylated flavonoid Nobiletin (NOB) as a circadian clock modulator that directly binds to and activates the ROR receptors in the core oscillator, markedly improving metabolic fitness in obese mice. Here, we show that NOB enhanced the oscillation of core clock genes in differentiated 3T3-L1 adipocytes, including ROR target genes such as Bmal1, Cry1, Dec1, and Dec2. NOB inhibited lipid accumulation in 3T3-L1 and SVF cells, concomitant with the dysregulated circadian expression of adipogenic …

BACKGROUND: Stereotactic ablative radiotherapy (SABR) is the standard treatment for medically inoperable early-stage non-small-cell lung cancer (NSCLC), but regional or distant relapses, or both, are common. Immunotherapy reduces recurrence and improves survival in people with stage III NSCLC after chemoradiotherapy, but its utility in stage I and II cases is unclear. We therefore conducted a randomised phase 2 trial of SABR alone compared with SABR with immunotherapy (I-SABR) for people with early-stage NSCLC.

METHODS: We did an open-label, randomised, phase 2 trial comparing SABR to I-SABR, conducted at three different hospitals in TX, USA. People aged 18 years or older …

Faculty, Staff and Students Publications

Environmental exposure to endocrine-disrupting chemicals (EDCs) is linked to the development of uterine fibroids (UFs) in women. UFs, non-cancerous tumors, are thought to originate from abnormal myometrial stem cells (MMSCs). Defective DNA repair capacity may contribute to the emergence of mutations that promote tumor growth. The multifunctional cytokine TGFβ1 is associated with UF progression and DNA damage repair pathways. To investigate the impact of EDC exposure on TGFβ1 and nucleotide excision repair (NER) pathways, we isolated MMSCs from 5-month-old Eker rats exposed neonatally to diethylstilbestrol (DES), an EDC, or to vehicle (VEH). EDC-MMSCs exhibited overactivated TGFβ1 signaling and reduced mRNA …

The Brink Of The Abyss: From Transcatheter Aortic Valve Implantation, To Impella, To Left Ventricular Assist Device Destination Therapy, Jake Kieserman, Megan Sheehan, Marisa Cevasco, Brian Mccauley, Ryan Prentice, Jay Giri, Joyce Wald

Journal of Shock and Hemodynamics

Acute valvular emergencies are common causes of cardiogenic shock. Patients with critical aortic pathologies causing shock frequently undergo percutaneous interventions for valve replacement. However, in cases of persistent cardiogenic shock after valve replacement, there are limited options for further mechanical support. In this case study, we report a patient with a prior history of aortic valve replacement who presented in cardiogenic shock. After a transcatheter aortic valve-in-valve replacement, he remained in persistent shock with worsening clinical parameters requiring escalating inotropic and vasopressor support. With input from a multidisciplinary care team, an Impella 5.5 (Abiomed, Inc.) was placed through the valve …


Directions Of Attack And Their Effectiveness Of Male Judo Medalists At The Olympic Competitions., Amar Ait Ali Yahia Sep 2023

Directions Of Attack And Their Effectiveness Of Male Judo Medalists At The Olympic Competitions., Amar Ait Ali Yahia

Baltic Journal of Health and Physical Activity

Introduction: To perform a technical action, the elite judo athlete examines the direction of attack relative to the opponent's body position. This study aimed to analyze and compare the most frequent and effective attack directions carried out by male Olympic medalists. Materials and Methods: A sample of 112 male medalists performed 3,664 attacks in four Olympic tournaments (2004–2016). ANOVA (one factor) determined inter and intra-Olympic comparisons, followed by the post hoc Bonferroni test (p< 0.05). Eta squared η2 and Cohen's d calculated the effect size, respectively. Results: Olympic medalists oriented their attacks principally in right forward (30.5±11.3%), left forward (29.9±10.5%), left backward (18.8±8.1%), and right backward (15.8±6.1%). The effectiveness of right forward (25.7±13.1%) and left forward (26.2±12.5%) dominates left backward (20.5±10.1%) and right backward (15.5±9.7%), respectively. In terms of frequencies and effectiveness, the contribution of secondary directions is negligible. Conclusions: Attacking in eight orientations made the defense vulnerable. Beside the uncertainty and unpredictability, they created more points of imbalance to overcome defensive issues.

Automatic Cardiac Mri Image Segmentation And Mesh Generation, Ziyuan Li Sep 2023

Automatic Cardiac Mri Image Segmentation And Mesh Generation, Ziyuan Li

McKelvey School of Engineering Graduate Student Theses & Dissertations

Segmenting and reconstructing cardiac anatomical structures from magnetic resonance (MR) images is essential for the quantitative measurement and automatic diagnosis of cardiovascular diseases [1]. However, manual evaluation of the time-series cardiac MRI (CMRI) obtained during routine clinical care are laborious, inefficient, and tends to produce biased and non-reproducible results [2]. This thesis proposes an end-to-end pipeline for automatically segmenting short-axis (SAX) CMRI images and generating high-quality 2D and 3D meshes suitable for finite element analysis. The main advantage of our approach is that it can not only work as a stand-alone pipeline for the automatic CMR image segmentation and mesh …

Phase Separation Of Protein Mixtures Is Driven By The Interplay Of Homotypic And Heterotypic Interactions, Mina Farag, Wade M Borcherds, Anne Bremer, Tanja Mittag, Rohit V Pappu

2020-Current year OA Pubs

Prion-like low-complexity domains (PLCDs) are involved in the formation and regulation of distinct biomolecular condensates that form via phase separation coupled to percolation. Intracellular condensates often encompass numerous distinct proteins with PLCDs. Here, we combine simulations and experiments to study mixtures of PLCDs from two RNA-binding proteins, hnRNPA1 and FUS. Using simulations and experiments, we find that 1:1 mixtures of A1-LCD and FUS-LCD undergo phase separation more readily than either of the PLCDs on their own due to complementary electrostatic interactions. Tie line analysis reveals that stoichiometric ratios of different components and their sequence-encoded interactions contribute jointly to the driving …

Impacts Of A Covid-19 Educational Video: Evaluation Of The Influence Of Race, Gender, Political Affiliation, Study Major, And Age On Vaccine Acceptance Among University Students, Audrey J. Lee, Tiffany T. Vu, Reina M. Sanz, Myo-Kyoung Kim

Pacific Faculty Work

Background: The World Health Organization (WHO) warns that vaccine hesitancy is an ongoing major global health threat. While vaccination against severe acute respiratory syndrome coronavirus (SARS-CoV-2) proves to be an effective strategy in protecting against the disease, vaccine hesitancy represents a major barrier to stopping the spread of the virus. Willingness for vaccination can be influenced by several factors, including education level and health literacy. Although several studies demonstrate the value of video educational programs in improving coronavirus disease 2019 (COVID-19) vaccine knowledge and acceptance, no studies to date have evaluated if race, gender, and other demographic factors impact the …


Fast Ripples Reflect Increased Excitability That Primes Epileptiform Spikes, Shennan A. Weiss, Itzhak Fried, Jerome Engel, Michael R. Sperling, Robert K. S. Wong, Yuval Nir, Richard J. Staba Sep 2023

Fast Ripples Reflect Increased Excitability That Primes Epileptiform Spikes, Shennan A. Weiss, Itzhak Fried, Jerome Engel, Michael R. Sperling, Robert K. S. Wong, Yuval Nir, Richard J. Staba

Department of Neurology Faculty Papers

The neuronal circuit disturbances that drive inter-ictal and ictal epileptiform discharges remain elusive. Using a combination of extra-operative macro-electrode and micro-electrode inter-ictal recordings in six pre-surgical patients during non-rapid eye movement sleep, we found that, exclusively in the seizure onset zone, fast ripples (200–600 Hz), but not ripples (80–200 Hz), frequently occur <300 ms before an inter-ictal intra-cranial EEG spike with a probability exceeding chance (bootstrapping, P < 1e−5). Such fast ripple events are associated with higher spectral power (P < 1e−10) and correlated with more vigorous neuronal firing than solitary fast ripple (generalized linear mixed-effects model, P < 1e−9). During the intra-cranial EEG spike that follows a fast ripple, action potential firing is lower than during an intra-cranial EEG spike alone (generalized linear mixed-effects model, P < 0.05), reflecting an inhibitory restraint of intra-cranial EEG spike initiation. In contrast, ripples do not appear to prime epileptiform spikes. We next investigated the clinical significance of pre-spike fast ripple in a separate cohort of 23 patients implanted with stereo EEG electrodes, who underwent resections. In non-rapid eye movement sleep recordings, sites containing a high proportion of fast ripple preceding intra-cranial EEG spikes correlate with brain areas where seizures begin more than solitary fast ripple (P < 1e−5). Despite this correlation, removal of these sites does not guarantee seizure freedom. These results are consistent with the hypothesis that fast ripple preceding EEG spikes reflect an increase in local excitability that primes EEG spike discharges preferentially in the seizure onset zone and that epileptogenic brain regions are necessary, but not sufficient, for initiating inter-ictal epileptiform discharges.

Candida-Induced Granulocytic Myeloid-Derived Suppressor Cells Are Protective Against Polymicrobial Sepsis, Shannon Esher Righi, Amanda J. Harriett, Elizabeth A. Lilly, Paul L. Fidel Jr., Mairi C. Noverr

School of Dentistry Faculty Publications

Polymicrobial intra-abdominal infections (IAI) can lead to life-threatening sepsis with significant morbidity and mortality, especially when pathogenic fungi are involved. We have employed an established clinically relevant mouse model of fungal/bacterial IAI and shown that immunization with low-virulence Candida species, that is, Candida dubliniensis, can induce responses that protect against sepsis via the suppression of lethal inflammation. This protection is dependent on long-lived Gr-1(+) polymorphonuclear leukocytes that display characteristics consistent with myeloid-derived suppressor cells (MDSCs) and trained innate immunity. Here we aimed to functionally and phenotypically characterize these protective Gr-1(+) leukocytes. Compared to nonimmunized control mice, we observed increased levels …
