The various health benefits of vinegar ingestion have been studied extensively in the<br/>literature. Moreover, emerging research suggests vinegar may also have an effect on mental<br/>health. Beneficial effects of certain diets on mood have been reported, however, the mechanisms<br/>are unknown. The current study aimed to determine if vinegar ingestion positively affects mood<br/>state in healthy young adults. This was a randomized, single blinded controlled trial consisting of<br/>25 subjects. Participants were randomly assigned to either the vinegar group (consumed 2<br/>tablespoons of liquid vinegar diluted in one cup water twice daily with meals) or the control<br/>group (consumed one vinegar pill daily with a meal), and the intervention lasted 4 weeks.<br/>Subjects completed mood questionnaires pre- and post-intervention. Results showed a significant<br/>improvement in CES-D and POMS-Depression scores for the vinegar group compared to the<br/>control. This study suggests that vinegar ingestion may improve depressive symptoms in healthy<br/>young adults.

Yoga has become one of the most popular contemporary health approaches practiced by young adults in the United States. It is an ancient mind and body practice with origins in Indian philosophy dating to over 5,000 years ago. Yoga combines physical postures, rhythmic breathing, and meditative exercises to offer the participants a unique, holistic mind-body experience. In this report, the Sutras first introduced by Patanjali, an ancient Indian sage, are broken down into modern definitions. Each sutra has its own unique mental and physical benefits that can be attained by college students. Yama encourages maintaining a personal moral code. Niyama allows for personal connection and self-awareness. Asana refers to the poses that are still commonly practiced today. Pranayama helps to practice deep breathing. Pratyahara offers a disconnect from the world around us. Dharana allows us to focus and hone in on one thought. Dyana promotes a continuous flow of focus in meditation. Samadhi is reaching a state of pure relaxation. All of these take time and practice, but when implemented in different aspects of daily life, college students can reduce their overall stress and anxiety to improve focus and success.

This project explores modern healthcare related disparities in Phoenix, Arizona, as well as the overarching historical structures that have influenced public health within the city. Historical and systemic racism, harmful housing policies, barriers preventing upwards economic mobility, and purposeful measures put in place by business leaders and city officials are all explored as factors impacting current disparities in access to care. In order to fully analyze the gaps in care, different areas, both high and low-income, are analyzed throughout history in order to understand shifting demographics and policies. The project concludes with an in-depth look at current public health efforts within Maricopa County, as well as with future policy recommendations.

A notable dilemma in the educational systems of current year is the lack of diversity in the faculty, administration, and curriculums. Diversity in education is colloquially understood to instill benefits in students that include development of sophisticated communication skills and heightened motivation, which may in turn have measurable benefits on health. In an effort to articulate the impact of introducing greater variegation into these systems and vocalize recommendations toward incorporating diversity into existing educational systems, the history of minority groups in schooling systems was analyzed, as were common health concerns for these communities. To this end, local students from Arizona State University were surveyed about their perceptions on diverse populations within their educational system. Moreover, these groups were also polled about how the messaging they receive about health and diversity may impact self-perceptions about their own health, as well as how applicable that messaging is with their own experiences.

Diabetes affects millions of people globally and can lead to other severe health complications when undiagnosed or not properly managed. The incidence of diabetes has rapidly increased over the past several years, however, not all individuals have access to affordable or convenient healthcare. We hypothesize that wastewater-based epidemiology (WBE) has the potential to assess community health status by analyzing biomarkers indicative of human health and disease, including diabetes. Used in tandem with current methods, monitoring indicators of diabetes in community wastewater could provide a comprehensive assessment tool for disease prevalence in large and small populations. Specifically, the proposed targeted biomarker evaluated in this study to indicate population-wide diabetes prevalence was 8-hydroxy-2’- deoxyguanosine (8-OHdG). This work combines a rigorous literature review and initial laboratory studies to explore the possibility of diabetes monitoring at the community level using WBE. Here, 24-hour composite wastewater samples were collected from within two wastewater sub-catchments of Greater Tempe, AZ. Overall goals of this study were to: i) Determine the feasibility to detect endogenous markers of diabetes in community wastewater; ii) Assess the potential impact of confounding factors, such as smoking, cancer, and atherosclerosis, through a literature analysis; and iii) Evaluate the socioeconomic status and demographics of the study population. Preliminary results of the experiments suggest this methodology to be feasible, as indicated by the observation of detectable signals of 8-OHdG in community wastewater collected from the sewer infrastructure; however, future work and continued experimentation will be required to address low signal intensity and assay precision and accuracy. Thus, the work presented here provides valuable proof-of-concept data, with detailed information on the method employed and identified opportunities to further determine the relationship between 8-OHdG concentrations in municipal wastewater and diabetes prevalence at the community level.
