Meeting, Moving, Mastering - A Text Analysis Of The Aesthetic Attractions Of 'Wild Swimming', Dagmar Dahl, Åsa I. Bäckström

International Journal of Aquatic Research and Education

Why are people fascinated by swimming in nature? This article addresses the aesthetic experiences of wild swimming as expressed by five wild swimming authors in their books. Drawing from aesthetic philosophy, we analyze the ways in which the appeal of wild swimming is described on three levels: the allure of water in the environment, the sensory encounter between water and the body, and the experience of moving in water. Furthermore, with reference to Seel’s concept of nature aesthetics (1996), the experience of wild swimming is analyzed in terms of contemplation, correspondence, and imagination. We can conclude that the special intensity …

The Application Of An Extracellular Vesicle-Based Biosensor In Early Diagnosis And Prediction Of Chemoresponsiveness In Ovarian Cancer, Meshach Asare-Werehene, Robert A Hunter, Emma Gerber, Arkadiy Reunov, Isaiah Brine, Chia-Yu Chang, Chia-Ching Chang, Dar-Bin Shieh, Dylan Burger, Hanan Anis, Benjamin K Tsang

Faculty, Staff and Student Publications

BACKGROUND: Ovarian cancer (OVCA) is the most fatal gynecological cancer with late diagnosis and plasma gelsolin (pGSN)-mediated chemoresistance representing the main obstacles to treatment success. Since there is no reliable approach to diagnosing patients at an early stage as well as predicting chemoresponsiveness, there is an urgent need to develop a diagnostic platform for such purposes. Small extracellular vesicles (sEVs) are attractive biomarkers given their potential accuracy for targeting tumor sites.

METHODS: We have developed a novel biosensor which utilizes cysteine-functionalized gold nanoparticles that simultaneously bind to cisplatin (CDDP) and plasma/cell-derived EVs, affording us the advantage of predicting OVCA chemoresponsiveness, …

The Impact Of Nutrition On The Mental And Physical Health Of Young Adults, Dareena El-Far

WRIT: Journal of First-Year Writing

Upon close examination by nutritional professionals, concern has arisen regarding the typical contents of a young adult diet. In terms of the rate at which young adults choose to consume nutritionally-dense food items, the rate at which nutrition-deficient junk food items are chosen over the former is significantly higher. Among further examinations of this issue by researchers, it has become evident that the nutritional decisions made by young adults are increasingly associated with several social, commercial, mental, educational, and economic influences. As a consequence of these factors, research has uncovered a connection between the consumption of a poor diet and …

Towards A Globalised Vision Of Aquatic Competence, Rita F. Pinto, Juan Antonio Moreno Murcia

International Journal of Aquatic Research and Education

Human interaction with the aquatic environment has always taken different forms to meet the needs of pleasure, survival, therapy or performance. The diversity of existing aquatic spaces presents itself as a challenge, due to their variety, dynamism, unpredictability and unrepeatable conditions. These factors potentiate an infinite number of possibilities for human response in interaction with the aquatic environment, with aquatic competence being the one that will be able to sustain all types of interaction. Thus, the aim of the proposal has been to present a new approach to the contextualisation of aquatic competence. After a literature review on the concept …

The Intersection Of Herbicide Policy, Exposure, And Health At The University Of Connecticut, Katherine Hayward

Honors Scholar Theses

Pesticides play an extremely complicated role in our everyday lives. From the water you use to make your coffee, to the breastmilk your neighbor provides for their child, to the lake your dog swims in, chemical pesticides or their byproducts have been found in nearly every corner of our lives. The chemicals used in synthetic herbicides, a subcategory of pesticides, have far reaching negative impacts on human health, biodiversity, and water quality. Despite there being numerous published studies on the relationships between pesticide exposures and health, there is still ongoing discord and controversy surrounding their role in our lives. After …

Faculty, Staff and Student Publications

Nononcogenic somatic mutations are thought to be uncommon and inconsequential. To test this, we analyzed 43,693 National Heart, Lung and Blood Institute Trans-Omics for Precision Medicine blood whole genomes from 37 cohorts and identified 7131 non-missense somatic mutations that are recurrently mutated in at least 50 individuals. These recurrent non-missense somatic mutations (RNMSMs) are not clearly explained by other clonal phenomena such as clonal hematopoiesis. RNMSM prevalence increased with age, with an average 50-year-old having 27 RNMSMs. Inherited germline variation associated with RNMSM acquisition. These variants were found in genes involved in adaptive immune function, proinflammatory cytokine production, and lymphoid …

Communicating Health: Misinformation And Mistrust In The Age Of Coronavirus, Chris Anstead

Undergraduate Theses

With one of the most advanced medical systems in the world, the Untied States still experienced an exceedingly high COVID-19 death rate per capita. Because biomedical therapies for COVID-19 were available, the focus of this review is on the social aspects of the COVID-19 response. By observing how Americans reacted to vaccination, masking, and social distancing guidelines, as well as how those guidelines were communicated to the general population from the public and private sectors, this thesis argues that the social and political aspects of the COVID-19 pandemic played a significant role in the outcome of the pandemic response. Additionally, …

A Novel Method For Measuring The Burden Of Breast Cancer In Neighborhoods, Russell K. Mcintire, Hee-Soon Juon, Scott W. Keith, Nicole L. Simone, Dexter Waters, Eleanor Lewis, Charnita Zeigler-Johnson

College of Population Health Faculty Papers

Community-based breast cancer prevention efforts often focus on women who live in the same neighborhoods, as they tend to have similar demographic characteristics, health behaviors, and environmental exposures; yet little research describes methods of selecting neighborhoods of focus for community-based cancer prevention interventions. Studies frequently use demographics from census data, or single breast cancer outcomes (e.g., mortality, morbidity) in order to choose neighborhoods of focus for breast cancer interventions, which may not be optimal. This study presents a novel method for measuring the burden of breast cancer among neighborhoods that could be used for selecting neighborhoods of focus. In this …

Faculty, Staff and Student Publications

In November 2021, Omicron BA.1, containing a raft of new spike mutations, emerged and quickly spread globally. Intense selection pressure to escape the antibody response produced by vaccines or severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection then led to a rapid succession of Omicron sub-lineages with waves of BA.2 and then BA.4/5 infection. Recently, many variants have emerged such as BQ.1 and XBB, which carry up to 8 additional receptor-binding domain (RBD) amino acid substitutions compared with BA.2. We describe a panel of 25 potent monoclonal antibodies (mAbs) generated from vaccinees suffering BA.2 breakthrough infections. Epitope mapping shows potent …

Brief Report: Out Of Sight Out Of Mind - Preventable Childhood Kidney Disease In The Far North, Johanna Neville, Allison Hempenstall, Caroline Taunton, Valmay Fisher, Malcolm Mcdonald

Journal of the Australian Indigenous HealthInfoNet

APSGN is an immune-mediated kidney disease that occurs after a Streptococcus pyogenes skin or throat infection in children and contributes to chronic kidney disease later in life. It is a disease of poverty and regrettably common in Aboriginal and Torres Strait Islander children. There have been seven documented APSGN outbreaks across Far North Queensland in the last nine years. Despite this disease being notifiable in both Western Australia and the Northern Territory, Queensland is yet to acknowledge the importance of early notification in the management of APSGN. Notification-driven publication of APSGN incidence should help raise its profile and stimulate better …

Rowan-Virtua School of Osteopathic Medicine Departmental Research

CONTEXT: Healthcare workers are at a high risk of infection during infectious disease outbreaks, such as the COVID-19 pandemic. Despite the availability of several vaccines against COVID-19, the absence of vaccination in patients and colleagues remains a continuous source of stress in healthcare workers. We conducted a survey of physician preceptors, both MDs and DOs, to explore the impact of differences in the patients' and colleagues' vaccination status on their well-being, stress, and burnout.

OBJECTIVES: The objective of this study is to determine whether exposure to unvaccinated patients and/or colleagues increases stress and burnout in physician preceptors by utilizing a …

Anthracycline-Containing And Taxane-Containing Chemotherapy For Early-Stage Operable Breast Cancer: A Patient-Level Meta-Analysis Of 100 000 Women From 86 Randomised Trials, Early Breast Cancer Trialists’ Collaborative Group (Ebctcg)

Faculty, Staff and Student Publications

BACKGROUND: Anthracycline-taxane chemotherapy for early-stage breast cancer substantially improves survival compared with no chemotherapy. However, concerns about short-term and long-term side-effects of anthracyclines have led to increased use of taxane chemotherapy without anthracycline, which could compromise efficacy. We aimed to better characterise the benefits and risks of including anthracycline, and the comparative benefits of different anthracycline-taxane regimens.

METHODS: We did an individual patient-level meta-analysis of randomised trials comparing taxane regimens with versus without anthracycline, and updated our previous meta-analysis of anthracycline regimens with versus without taxane, as well as analysing 44 trials in six related comparisons. We searched databases, including …

Department of Medical Oncology Faculty Papers

Androgen deprivation therapy is the cornerstone of prostate cancer therapy. Recent studies have revealed an association between androgen deprivation therapy and cardiovascular adverse effects such as myocardial infarction and stroke. This review summarizes the available research on the cardiovascular risk of men using androgen deprivation therapy. We also discuss racial disparities surrounding both prostate cancer and cardiovascular disease, emphasizing the importance of biological/molecular and socioeconomic factors in assessing baseline risk in patients beginning androgen ablation. Based on the literature, we provide recommendations for monitoring patients who are at high risk for a cardiovascular adverse event while being treated on androgen …

Faculty, Staff and Students Publications

Background: The US-Mexico border is a medically underserved region where survival disparities have been observed in adults diagnosed and treated for various malignancies. Studies examining survival disparities among children living in this region and diagnosed with cancer are lacking. The objective of this study was to evaluate the impact of border residence on survival among children with acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML), and living near the Texas-Mexico border at the time of their diagnosis. The authors hypothesized that this group experiences inferior survival compared with patients with childhood leukemia living in nonborder areas.

Methods: The authors conducted …

By The Time You Finish Reading This There Will Be 10 Diabetic Foot Amputations, Cassidy Begley

Health Sciences Student Scholarship

People of color with diabetes in rural low-income communities are more likely to encounter barriers to podiatric care than their white counterparts. Studies show that rural Americans with diabetic foot ulcers have a fifty percent increased risk for foot amputation. Proper foot care is critical to diabetic health by ensuring the maintenance of mobility and quality of life. As the U.S. population ages and diabetes diagnoses increase, individuals across the country develop mobility and foot-related problems. While this is a general issue, nonwhites in low-income rural areas are disproportionately impacted. Podiatrists play a key role in managing a multitude of …

Lessons From Canada’S Notice Of Compliance With Conditions Policy For The Life-Cycle Regulation Of Drugs, Melanie Mcphail, Howard Zhang, Zohra Bhimani, Tania M. Bubela

Office of the Provost

Innovative health technologies are not well regulated under current pathways, leading regulators to adopt contextual, life-cycle regulatory models, which authorize drugs based on earlier clinical evidence subject to the conduct of post-market trials that confirm clinical benefit and safety. In this paper, we evaluate all drugs authorized in Canada under the Notice of Compliance with conditions (NOC/c) policy from 1998 to 2021 to analyze its function, identify challenges and areas for improvement, and make recommendations to inform Health Canada's regulatory reforms. We analyzed a sample of 148 drugs authorized between 1998 and 2021, including characteristics about the pre- and post-market …

Blood Pressure Surge With Alarm Is Reduced After Exercise And Diet Intervention In Firefighters, Deborah L Feairheller, Macie Smith, Megan Carty, Emily H Reeve

College of Population Health Faculty Papers

BACKGROUND: Cardiac-related incidents are a public health concern for tactical occupations, and cardiovascular disease rates are higher in these populations compared with civilians. Research is needed to examine blood pressure (BP) responses in firefighters. The pager alert is one occupational hazard, and it is unknown if lifestyle change can reduce the systolic surge response.

PURPOSE: To measure BP surge with alarm in firefighters to determine whether the magnitude is lower after a 6-week tactical exercise and Mediterranean-diet intervention.

Structural Foundations Of Potassium Selectivity In Channelrhodopsins, Sukyeong Lee, Sang Bum Lee, Nuri Sung, Wendy W Xu, Changsoo Chang, Hyun-Eui Kim, Andre Catic, Francis T F Tsai

Faculty, Staff and Student Publications

Mitochondria are critical to cellular and organismal health. To prevent damage, mitochondria have evolved protein quality control machines to survey and maintain the mitochondrial proteome. SKD3, also known as CLPB, is a ring-forming, ATP-fueled protein disaggregase essential for preserving mitochondrial integrity and structure. SKD3 deficiency causes 3-methylglutaconic aciduria type VII (MGCA7) and early death in infants, while mutations in the ATPase domain impair protein disaggregation with the observed loss-of-function correlating with disease severity. How mutations in the non-catalytic N-domain cause disease is unknown. Here, we show that the disease-associated N-domain mutation, Y272C, forms an intramolecular disulfide bond with Cys267 and …

“They’Re Still Trying To Wrap Their Head Around Forever”: An Anatomy Of Hope For Spinal Cord Injury Patients, William A. Lucas

USF Tampa Graduate Theses and Dissertations

This dissertation draws on ethnographic data to investigate the nature of spinal cord injury (SCI) rehabilitation in Central Florida, using participant observation and interview data to understand how people with SCI (pwSCI) conceptualize their own disabilities after experiencing such radical alterations in their subjectivities. Using case studies and ethnographic vignettes, it argues that the extreme double binds in which pwSCI find themselves (where they are personally ordinarily disabled and socially extraordinarily novel; and where they are enabled resources to pursue “hopeful” therapy modalities while being designated as hopelessly disabled) is further polarized by the various legislative regimes of truth in …

Metabolic Dysregulation Impairs Lymphocyte Function During Severe Sars-Cov-2 Infection, Sanjeev Gurshaney, Anamaria Morales-Alvarez, Kevin Ezhakunnel, Andrew Manalo, Thien-Huong Huynh, Jun-Ichi Abe, Nhat-Tu Le, Daniela Weiskopf, Alessandro Sette, Daniel S Lupu, Stephen J Gardell, Hung Nguyen

Cellular metabolic dysregulation is a consequence of SARS-CoV-2 infection that is a key determinant of disease severity. However, how metabolic perturbations influence immunological function during COVID-19 remains unclear. Here, using a combination of high-dimensional flow cytometry, cutting-edge single-cell metabolomics, and re-analysis of single-cell transcriptomic data, we demonstrate a global hypoxia-linked metabolic switch from fatty acid oxidation and mitochondrial respiration towards anaerobic, glucose-dependent metabolism in CD8+Tc, NKT, and epithelial cells. Consequently, we found that a strong dysregulation in immunometabolism was tied to increased cellular exhaustion, attenuated effector function, and impaired memory differentiation. Pharmacological inhibition of mitophagy with mdivi-1 reduced excess glucose …
