Peripheral Vascular Function in Young Adults with Increased Risk of Cardiometabolic Disease
Get PDFObjective: To determine if young adults with elevated metabolic syndrome severity scores (MetSindex) suffer from peripheral vasculature dysfunction.
Methods: Mean arterial pressure (MAP), Femoral (FBF) and Brachial Blood flow (BBF), Femoral (FVC) and Brachial Vascular Conductance (BVC), and Tissue Saturation Index (TSI) were assessed in twenty-four age (19 + 2.25 years), Sex (male: n=18; female: n=6) and Race (White: n=4; Black/African American: n=4; Asian: n=16) matched individuals during post-occlusive reactive hyperemia (RHBF), passive limb movement (PLM) and Functional Sympatholysis (FS) trials. Carotid femoral pulse wave velocity (cfPWV) was also collected at baseline, and all values were compared between the Control (Con; negative MetSindex score) and Elevated Risk (ER; positive MetSindex score) groups using a combination of independent samples t-tests and repeated measures analyses of variance (RMANOVA).
Results: As expected, blood flow and vascular conductance significantly increased during all RHBF and PLM trials across both groups (all p0.591), PLM responses (all p\u3e0.313), brachial RHBF responses (all p\u3e0.132), or FS responses (all p\u3e0.446). Likewise, no group differences were observed for PWV (Con: mean= 5.14 + 1.69m/s; ER: mean= 5.18 + 1.84m/s; p=0.953).
Conclusions: The current findings suggest that peripheral vascular function appears to be unaffected in young adults presenting with elevated MetSindex score. Our findings also suggest that MetSindex may provide use as an “early warning” system for young adults at risk of MetS-associated vascular dysfunction and highlights the need for further cardiovascular assessments in these individuals
Projected Range Shift of the Atlantic Surfclam, Spisula solidissima, and the Ocean Quahog, Arctica islandica, Under Climate-Induced Benthic Warming: Forecasting Fishery Influence in the Mid-Atlantic Bight Throughout the 21st Century
No full textThe Atlantic surfclam, Spisula solidissima, and ocean quahog, Arctica islandica, are biomass dominant bivalve species on the eastern North American continental shelf, both supporting lucrative commercial fisheries in the Mid-Atlantic with a combined value of $53.6 million in ex-vessel revenue per year. Rapid climate change is expected to modify the geographic range of these bivalve populations across the Mid-Atlantic Bight (MAB), suggesting transformative consequences for the surfclam fishery. This study forecasted future distributions of the two species from years 2016 – 2095, based on projected bottom water temperatures and a temperature-dependent population dynamics model, to project subsequent fishery-based indicators using a Spatially Explicit, agent-based Fisheries and Economics Simulator (SEFES). Simulations showed a positive trend in Atlantic surfclam biomass throughout the next three-quarters of the century as the clam’s range continues to shift offshore and northward into habitat previously occupied by the ocean quahog, restricting ocean quahog habitat to offshore Long Island by 2095. Regional surfclam populations expand into deeper waters off New Jersey, Long Island, and southern New England starting in the early 2050s, whereas Georges Bank and Delmarva populations begin to gradually decline. A general decrease in fishing mortality is projected, with a simultaneous increase in catch and LPUE (landings per unit effort), signaling future potential growth in the surfclam fishery. These results can inform industries dependent on this resource, and other competing coastal users, by providing a basis for the development of anticipatory management for the socio-ecological and economic impacts that may result from future changes in range distribution
Ultrasound-Guided Erector Spinae Plane Block: An Objective Structured Clinical Examination for First-Year Anesthesia Providers
Get PDFThe use of ultrasound-guided regional anesthesia (UGRA) in anesthetic practice is an invaluable tool for anesthesia providers to implement into their daily practice. One of these regional techniques is the erector spinae plane block (ESPB) which has anesthetic implications in numerous surgical procedures including cervical spine, thoracolumbar spine, thoracic wall, and chest wall procedures. Because of the novelty of this regional anesthetic technique, it is important to educate first-year anesthesia providers about the implications, skillset, and complications of the ESPB.
To bridge the gap between didactic knowledge and clinical practice in first-year anesthesia providers, an objective structured clinical examination (OSCE) was created to formulate a standardized evaluation tool that educates and instills confidence into the providers in a simulated clinical scenario before they enter clinical practice. The OSCE will better educate anesthesia providers in the knowledge and skills to perform the ESPB so that they may implement the ESPB into daily anesthetic practice. Doing so will lead to an improved delivery of perioperative analgesia and reduce opioid use/misuse in a variety of patient populations.
To evaluate the DNP project, a mixed methods qualitative-quantitative randomized controlled trial (RCT) was performed. A sample size of ten first-year anesthesia providers in The University of Southern Mississippi (USM) Nurse Anesthesia Program (NAP) voluntarily consented to participate in this study. The participants were randomly assigned to either a traditional or OSCE learning group, each containing five members.
A two-tailed sample t-test was applied to analyze the data collected from the simulation scenario where the participants performed the ESPB using ultrasound-guidance. Afterward, each one answered a short survey that included both qualitative and quantitative questions to evaluate the experience. Even though the data suggested there was no significant difference between the two groups, the OSCE group demonstrated increased confidence in performing the ESPB, the ability to identify landmarks, and satisfaction with the learning materials. Based on these results, the importance of this DNP project was validated and demonstrated that the first-year anesthesia providers were capable and confident in implementing the ESPB into clinical practice
Doing Their Own Thing : The Impact of Second-Wave Feminism at the University of Southern Mississippi
Get PDFSecond-Wave Feminism was largely responsible for transforming American society’s beliefs about gender roles. However, there is very little attention given to the impact that feminism had on cultural transformations in the South. Much of the historiography of feminism and women’s liberation only covers the most radical events and leaders of the 1970s, and it neglects to point out the smaller forms of resistance that ultimately made the movement successful. During this period, the South, and specifically southern campuses, had the reputation of being against women’s liberation because there was not much evidence of resistance comparable to that of northern campuses. However, the events that took place on the University of Southern Mississippi’s campus during the late 1960s to the 1980s illustrate that the impact of Second-Wave Feminism was felt nationwide, even in the Deep South.
I will argue that women at USM displayed acts of liberal feminism, demonstrating the impacts of the national movement. To make this argument, I will use the University of Southern Mississippi’s campus as a lens to analyze the complexities of Southern feminism, and how not all resistance during this period needed to be radical to be effective. I will use changes in ideas about dress codes, curfews, and the changes to the School of Home Economics on USM’s campus to reveal that feminist activism was not only experienced on the more radical campuses. Without analyzing smaller forms of resistance in the Deep South, the understanding of Second-Wave Feminism is largely incomplete
The Effect of Remote Work on Career Success in the Accounting Profession
Get PDFThis study analyzed the results of career success assessments of hypothetical public accountants working remotely and in a traditional office setting to determine if remote work affects assessments by partners, managers, and staff accountants. Subjects were randomly assigned resumes that included indications of either remote work or traditional in-office work. Resumes were otherwise identical. After an initial assessment of an assigned hypothetical accountant, subjects were asked to recommend activities that would increase the likelihood of future career success. Subjects were then told that the hypothetical accountant engaged in the recommended activity and were provided a description of a high or low level of achievement. This process was repeated, and subjects, then, evaluated the hypothetical accountant in light of this new information. The results suggest that remote workers are not penalized by partners, managers, or staff when assessing the likelihood of future career success. These results are consistent with comparisons of actual and appropriate levels of remote work. Subjects seemed comfortable with current or even higher levels of remote work
Musselwhite: A Case Study in the Development of Modern Legend in the American South
Get PDFThe development of modern legend is widely researched, and there are many theories on the involvement of rumor and truth in the creation of folk stories. However, there are often few opportunities to look at the development of a modern legend in detail from beginning to end. The legend of Luther Musselwhite is unique in that it begins at a relatively fixed time, and the generations present during that time are still available to interview. This case study traces the development of this modern legend in Mississippi and analyzes the possible motivations for the spread and development of modern legends in the American South. The analysis concludes that modern legend reflects community and societal issues, and that the boundary between rumor and legend lies where the story began to be used for a specific purpose separate from rational warning
Tense Indifference: An Examination of Integration in Two Cities in Marengo County, Alabama
Get PDFFor decades, the city of Demopolis, Alabama, in Marengo County has been viewed by West Alabama administrators as a “beacon of hope” in terms of race relations because it successfully integrated its public schools and managed to keep private segregation academies at bay. In the neighboring city of Linden, however, integration was far less successful, with a a segregated private school siphoning off the white students and eroding white support for public education. dominating and destroying the educational structure of the city. In this paper, I delve into how the dichotomy between these two nearby cities was created by the attitudes of the people who lived in them. Where Demopolis reacted to integration with a tense indifference that allowed integration to prosper with lingering side effects, Linden reacted with hostility, a reaction that would negatively affect the city for decades to come

WE WON\u27T GIVE UP ON THIS UNTIL WE GET IT : THE WOMEN\u27S JURY MOVEMENT IN MISSISSIPPI, 1938-1968
No full textAfter the ratification of the Nineteenth Amendment in 1920, many former suffragists and women’s rights activists began statewide campaigns for jury service for women. While the women’s suffrage movement has been studied extensively, the subsequent movement for women’s jury service has largely been overlooked within historical scholarship. Mississippi, which became the last state to legalize women’s jury service in 1968, has been notably overlooked in historiography despite its connection to the civil rights movement. Women’s organizations including the League of Women Voters and the Mississippi Federation of Business and Professional Women’s Clubs spent decades advocating for women’s jury service. However, they struggled to find success.
This thesis will argue that while activists advocated tirelessly for women’s jury service in Mississippi, it was the civil rights movement that helped lead to the jury movement’s success. As civil rights advancements were made during the 1960s, more legislators began supporting women’s jury rights. This newfound support was likely not coincidental but the effect of segregationist politicians searching for ways to resist civil rights. Legislators expected white women jurors to uphold the racial status quo. I will use primary and secondary sources to show the arguments for and against women’s jury service. These sources also demonstrate the work of jury activists and the complicated history of the women’s jury movement. By using these sources, I will show how the changes happening in Mississippi helped lead to legislation legalizing women’s jury service
