The effects of a long-term combat deployment on a soldier's physical fitness are not well understood. In active duty soldiers, combat deployment reduced physical fitness compared to pre-deployment status, but no similar research has been performed on Army National Guard soldiers. This study is the first to identify physical fitness changes in Arizona National Guard (AZNG) soldiers following deployment to a combat zone and to assess the relationships between physical fitness and non-combat injuries and illness (NCII). Sixty soldiers from the Arizona National Guard (AZNG) completed a battery of physical fitness tests prior to deployment and within 1-7 days of returning from a 12-month deployment to Iraq. Pre and post-deployment measures assessed body composition (Bod Pod), muscular strength (1RM bench press, back-squat), muscular endurance (push-up, sit-up), power (Wingate cycle test), cardiorespiratory fitness (treadmill run to VO2 peak), and flexibility (sit-and-reach, trunk extension, shoulder elevation). Post deployment, medical records were reviewed by a blinded researcher and inventoried for NCII that occurred during deployment. Data were analyzed for changes between pre and post-deployment physical fitness. Relationships between fitness and utilization of medical resources for NCII were then determined. Significant declines were noted in mean cardiorespiratory fitness (-10.8%) and trunk flexibility (-6.7%). Significant improvements were seen in mean level of fat mass (-11.1%), relative strength (bench press, 10.2%, back-squat 14.2%) and muscular endurance (push-up 16.4%, sit-up 11.0%). Significant (p < 0.05) negative correlations were detected between percentage change in fat mass and gastrointestinal visits (r = -0.37); sit-and-reach and lower extremity visits (r= -0.33); shoulder elevation and upper extremity visits (r= -0.36); and cardiorespiratory fitness and back visits (r= -0.31); as well as behavioral health visits (r= -0.28). Cardiorespiratory fitness changes were grouped into tertiles. Those who lost the greatest fitness had significantly greater number of NCII visits (8.0 v 3.1 v 2.6, p = .03). These data indicate a relationship between the decline in cardiorespiratory fitness and an overall increase in utilization of medical resources. The results may provide incentive to military leaders to ensure that soldiers maintain their cardiorespiratory fitness throughout the extent of their deployment.

The nineteenth-century invention of smallpox vaccination in Great Britain has been well studied for its significance in the history of medicine as well as the ways in which it exposes Victorian anxieties regarding British nationalism, rural and urban class struggles, the behaviors of women, and animal contamination. Yet inoculation against smallpox by variolation, vaccination’s predecessor and a well-established Chinese medical technique that was spread from east to west to Great Britain, remains largely understudied in modern scholarly literature. In the early 1700s, Lady Mary Wortley Montagu, credited with bringing smallpox variolation to Great Britain, wrote first about the practice in the Turkish city of Adrianople and describes variolation as a “useful invention,” yet laments that, unlike the Turkish women who variolate only those in their “small neighborhoods,” British doctors would be able to “destroy this [disease] swiftly” worldwide should they adopt variolation. Examined through the lens of Edward Said’s Orientalism, techno-Orientalism, and medical Orientalism and contextualized by a comparison to British attitudes toward nineteenth century vaccination, eighteenth century smallpox variolation’s introduction to Britain from the non-British “Orient” represents an instance of reversed Orientalism, in which a technologically deficient British “Occident” must “Orientalize” itself to import the superior medical technology of variolation into Britain. In a scramble to retain technological superiority over the Chinese Orient, Britain manufactures a sense of total difference between an imagined British version of variolation and a real, non-British version of variolation. This imagination of total difference is maintained through characterizations of the non-British variolation as ancient, unsafe, and practiced by illegitimate practitioners, while the imagined British variolation is characterized as safe, heroic, and practiced by legitimate British medical doctors. The Occident’s instance of medical technological inferiority brought about by the importation of variolation from the Orient, which I propose represents an eighteenth-century instance of what I call medical techno-Orientalism, represents an expression of British anxiety over a medical technologically superior Orient—anxieties which express themselves as retaliatory attacks on the Orient and variolation as it is practiced in the Orient—and as an expression of British desire to maintain medical technological superiority over the Orient.

The social determinants of health (SDOH) represent factors that impact the health and effectiveness/compliance of a treatment plan for a patient. The SDOH include such factors as economic stability, education, home and community context, access to healthcare, neighborhood and built environment, and personal behavior. The purpose of this study is to determine the extent of collection and integration of SDOH into clinical practice, and the usefulness of this information in medical decision making. Following a thorough literature review, an online survey was deployed to physicians and administrators around the country, with the aim of answering the following questions: 1) Do provider practices collect information on a patient's social determinants of health? 2) If yes, how is that information being used, if at all? 3) If not, what is preventing them from doing so? 4) Do the answers to questions 1-3 differ based on the type of payment model (Fee-for-Service or Capitation) to which the practice is subject? The results of the study suggest that fee-for-service payment environments present less incentive to use a patient's SDOH in medical decision making.

Cardiovascular disease is one of the most deadly outcomes of end stage renal disease. Bioelectrical impedance is a intriguing, yet unproven method of measuring fluid buildup in the heart, and is marketed as a early diagnostic tool for onset of cardiovascular disease. In this study, selenium supplements were given to a cohort of dialysis patients in the Phoenix metro area and their fluid tolerance was measured with thoracic biolectrical impedance. BNP was used as a correlate to see if bioelectrical impedance was correlated with heart disease. The study found no correlation between BNP and bioelectrical impedance and thus was not an accurate diagnostic tool in a medical setting.

Purpose: The purpose of this study was to examine the acute effects of two novel intermittent exercise prescriptions on glucose regulation and ambulatory blood pressure. Methods: Ten subjects (5 men and 5 women, ages 31.5 ± 5.42 yr, height 170.38 ± 9.69 cm and weight 88.59 ± 18.91 kg) participated in this four-treatment crossover trial. All subjects participated in four trials, each taking place over three days. On the evening of the first day, subjects were fitted with a continuous glucose monitor (CGM). On the second day, subjects were fitted with an ambulatory blood pressure monitor (ABP) and underwent one of the following four conditions in a randomized order: 1) 30-min: 30 minutes of continuous exercise at 60 - 70% VO2peak; 2) Mod 2-min: twenty-one 2-min bouts of walking at 3 mph performed once every 20 minutes; 3) HI 2-min: eight 2-min bouts of walking at maximal incline performed once every hour; 4) Control: a no exercise control condition. On the morning of the third day, the CGM and ABP devices were removed. All meals were standardized during the study visits. Linear mixed models were used to compare mean differences in glucose and blood pressure regulation between the four trials. Results: Glucose concentrations were significantly lower following the 30-min (91.1 ± 14.9 mg/dl), Mod 2-min (93.7 ± 19.8 mg/dl) and HI 2-min (96.1 ± 16.4 mg/dl) trials as compared to the Control (101.1 ± 20 mg/dl) (P < 0.001 for all three comparisons). The 30-min trial was superior to the Mod 2-min, which was superior to the HI 2-min trial in lowering blood glucose levels (P < 0.001 and P = 0.003 respectively). Only the 30-min trial was effective in lowering systolic ABP (124 ± 12 mmHg) as compared to the Control trial (127 ± 14 mmHg; P < 0.001) for up to 11 hours post exercise. Conclusion: Performing frequent short (i.e., 2 minutes) bouts of moderate or high intensity exercise may be a viable alternative to traditional continuous exercise in improving glucose regulation. However, 2-min bouts of exercise are not effective in reducing ambulatory blood pressure in healthy adults.

Heart failure is a major worldwide health concern and is the leading cause of hospitalization among elderly Americans. Approximately 50% of those diagnosed with heart failure have heart failure with preserved ejection fraction (HFPEF). HFPEF presents a therapeutic dilemma because pharmacological strategies that are effective for the treatment of heart failure and reduced ejection fraction have failed to show benefit in HFPEF. Long term moderate intensity exercise programs have been shown to improve diastolic function in patients HFPEF. High intensity interval training (HIIT) has been shown to improve diastolic function in patients with heart failure and reduced ejection fraction. However, the effects of high intensity interval training in patients with HFPEF are unknown. Fourteen patients with HFPEF were randomized to either: (1) a novel program of high-intensity aerobic interval training (n = 8), or (2) a commonly prescribed program of moderate-intensity (MOD) aerobic exercise training (n = 6). Before and after four weeks of exercise training, patients underwent a treadmill graded exercise test for the determination of peak oxygen uptake (VO2peak), a brachial artery reactivity test for assessment of endothelium-dependent flow-mediated dilation (BAFMD), aortic pulse wave velocity assessment as an index of vascular stiffness and two-dimensional echocardiography for assessment of left ventricular diastolic and systolic function. I hypothesized that (1) high-intensity aerobic interval training would result in superior improvements in FMD, aortic pulse wave velocity, VO2peak, diastolic function and, (2) changes in these parameters would be correlated with changes in VO2peak. The principal findings of the study were that a one month long high intensity interval training program resulted in significant improvements in diastolic function as measured by two-dimensional echocardiography [pre diastolic dysfunction (DD) grade - 2.13 + 0.4 vs. post DD grade - 1.25 + 0.7, p = 0.03]. The left atrial volume index was reduced in the HIIT group compared to MOD ( - 4.4 + 6.2 ml/m2 vs. 5.8 + 10.7 ml/m2, p = 0.02). Early mitral flow (E) improved in the HIIT group (pre - 0.93 + 0.2 m/s vs. post - 0.78 + 0.3 m/s, p = 0.03). A significant inverse correlation was observed between change in BAFMD and change in diastolic dysfunction grade (r = - 0.585, p = 0.028) when all the data were pooled. HIIT appears to be a time-efficient and safe strategy for improving diastolic function in patients with heart failure and preserved ejection fraction. These data may have implications for cardiovascular risk reduction in this population.

Most individuals entering college are taking responsibility for their own health for the first time. Students are used to having a parent or guardian nearby to diagnose and provide remedies for common health issues. Entering college, whether in a different city or just down the road, means they must assume those responsibilities themselves. Navigating that transition can be difficult for college students. A large majority of students turn to internet health resources, such as WebMD, for health information. However, studies show that despite overall internet savvy, college students are not very skilled at finding legitimate health information online. Therefore, a health resource designed specifically for college students would be a valuable resource for many students at ASU. Working with local Phoenix physician Doug Lakin, I and a team of other Barrett students revised Dr. Lakin's healthcare guide, Thrive 101: Health & Wellness for College Students. I was responsible for the guide's second chapter, which provides information on specific illnesses and injuries. I conducted a literature review to discover the best practices for communicating medical information. I found that using short sentences, simple words, bullet point lists, numbered lists, and subheadings improved the effectiveness of a health resource. I also found that health information seekers want resources to be tailored specifically for them. They want personalized resources. Personalization means including health information that the intended reader wants, excluding the health information the reader does not want, as well as featuring personal anecdotes from individuals like the reader dealing with health problems like the reader's. I applied what I discovered to Thrive 101. I reorganized the chapter I was assigned, incorporating subheadings and clear organization of the information. I also eliminated information I judged irrelevant to college students and brainstormed what information was missing that college students would benefit from. At this time, the revision team has not gotten to the point where we are researching and writing new information, but we do have lists of items we want to include. The information already in the guide I reformatted into bulleted and numbered lists where possible. As with the new information, we have not begun to revise the guide on a prose level, shortening the sentences and simplifying the vocabulary, but we intend to work into the summer to finish our revisions.

This thesis focuses on Bram Stoker’s 1897 British novel 'Dracula' and its association of medical technology with a myriad of Victorian British societal anxieties, facilitating an examination of current and historical fears about medical intervention and medical innovation. Dracula’s parallel yet opposite portrayals of blood transfusion and vampirism allow fears of medical technology to be exaggerated and explored within the realm of the supernatural. In Dracula and today, the desire to restore the health of ourselves and our loved ones is accompanied by fears that medical treatment will cause harm; will reshape our conceptualization of death and thus our relationship with death; and, as new technologies with unestablished consequences are employed, that medical intervention may in fact erode our basic identity and humanity.

In this study, we propose and then assess the efficacy of a new approach to static suspension to correct for facial paralysis. Our method involves placing barbed sutures through the superficial muscular aponeurotic system (SMAS) and anchoring them in the temporal fascia parallel to the underlying facial muscles. We first analyzed the ability of this procedure to improve facial symmetry by comparing the degree of asymmetry between the paralyzed and unaffected sides of a patient's face (N=10) prior to and following surgery. Then, to determine if symmetry is improved as a result of placing the sutures parallel to the direction of facial muscle forces, we measured the vectors of levator labii superioris and zygomaticus major in cadaver hemifaces (N=3) and compared them to the angles of the vectors of correction from the patient sample to angles of muscle vectors in three facial hemispheres from cadaver controls. Results indicate that: (1) facial symmetry was significantly improved in these patients and (2) this improvement. We conclude that, compared to existing protocols, our novel surgical method is a better means of static suspension for reconstruction following onset of facial paralysis as it is simple to perform, easy to replicate, able to be post-operatively adjusted in-office, has a good long-term prognosis, and, as we have demonstrated, effectively corrects the appearance of asymmetry by working with the underlying facial anatomy.

The purpose of this study is to analyze what barriers of care exist within the Senor de los Milagros community in Trujillo, Peru and how these barriers to care can identify shortcomings in the public healthcare system. This study is a collaboration of field research and outside literature. The research conducted was done via structured interviews with 15 participants, all promotoras (mothers of the community) and their husbands in the Senor de los Milagros community of Trujillo, Peru. Summaries and quotes from these interviews were uploaded and quantified to identify common barriers to care derived from socioeconomic and cultural determinants . Although this was on the main focus of the study, observations and conversations with healthcare staff and patients showed that the two most specific barriers found when data was analyzed were the wait times of public sector facilities and quality of care within these facilities. These barriers to care did not stop the promotoras from seeking care at MINSA facilities, but it does pose the questions as to how it affects healthcare-seeking behaviors and if this affects long-term healthcare outcomes.
