Description
Human trafficking is a widespread global health issue impacting communities both locally and globally. Despite its prevalence in our world, there is a lack of education amongst healthcare providers. Research suggests that more than 80 percent of human trafficking victims encountered one or more healthcare professionals while being trafficked. Of these providers encountered, 60 percent were emergency department personnel (Lederer & Wetzel, 2014). Although emergency department personnel have a high rate in interaction with victims, less than 5 percent have received formal training regarding human trafficking (Lederer & Wetzel, 2014). It is my goal to better educate current and future healthcare professionals on human trafficking. Through education, more victims can be recognized and be offered the resources they deserve. In order to do this, I want to understand current perceptions, knowledge, and beliefs that healthcare personnel have, and how education affects these perceptions. To gain this information, I will distribute the same survey to healthcare professionals before and after receiving a formal training on human trafficking. Through this survey, I hope to better understand how education affects people’s perceptions, knowledge, and beliefs on human trafficking.

Description
Background: Despite a multitude of health initiatives, obesity rates in America have continued to increase yearly, with obese or overweight people making up two-thirds of the population. Due to a lack of significant results from diet and weight-loss medication, new methods of weight-loss are increasingly considered. This paper looks beyond traditional Western treatments for weight loss and will analyze views and treatments for overweight and obesity in traditional Chinese medicine (TCM).
Methods: Three databases were used to search for papers published after 2010 until October 2019 discussing obesity, overweight and TCM. No forms of Chinese medicine were excluded from the search. Studies were excluded if they did not meet the date criteria or if they overlapped with papers found in other databases.
Results: Six of the selected papers covered acupuncture (electro, balance or catgut embedding acupuncture methods) either jointly with other treatments or alone, one exclusively on moxibustion and three studies on three different types of TCM herbal medicine. Each study showed a statistically significant effect on body mass index (BMI) value decrease or total weight loss (TWL). The six acupuncture papers all showed statistical significance at the 95% CI against control groups (sham acupuncture or no acupuncture) and against before-treatment BMI values or TWL values.
Conclusion: Of the treatments reviewed, almost all acupuncture studies were shown to be consistently effective in treating overweight or obese individuals within this selection of studies, as well as in another meta-analysis. This may be due to acupuncture’s ties to a neuroendocrine mechanism. Future studies should further explore the neuroendocrine connection between acupuncture and weight loss. Herbal medication was also shown to have a significant effect in reducing weight in each study; however, two studies used mice or rats as subjects, therefore understanding the effects on human subjects is limited.

ABSTRACT
Overview: There has been very little research done into the topic of mental illness in general, and Alzheimer’s Disease specifically, in Guatemala. The existing research accounts for prevalence of mental illness in Guatemala with an estimated prevalence of a mental illness of 27.8% (Guatemalan Government, 2009). Alzheimer’s Disease is less well researched.
Research Question: This research addresses this gap in knowledge by focusing on the stigma felt toward people who had Alzheimer’s Disease and Related Dementia (ADRD) by the people of Guatemala.
Participants: One-hundred twenty-four individuals over the age of 18 were recruited for participation. Participants were recruited through opportunity samples in artisan markets in Antigua.
Procedures: Participants completed a survey including demographic questions, the Dementia Attitudes Scale (O’Connor & McFadden 2010), as well as open-ended questions regarding the causes, symptoms, and treatments for Alzheimer’s. The study was conducted from July 2, 2018 to August 2, 2018.
Results: The average DAS score of 100.31± 14.01 found in this study is similar to results from other studies conducted in the United States (O'Connor & McFadden, 2010). Factor analysis did not verify the existence of sub-scales in the survey, as found in previous studies. The free-response questions indicated that many people may believe that ADRD is an inherited disease or one that is caused by factors outside of their control.
Conclusions: The high DAS score of 100.31± 14.01 matches other studies that used the DAS. Scores of 103.51± 13.43 (Scerri & Scerri, 2013) were reported in other studies and interpreted as positive as it relates to stigma. This points to a low stigma level in Guatemala. The failure to verify the sub-scales leads to the conclusion that although scales are validated in western nations, they may not be culturally portable. The DAS scale may not be measuring the same thing in this sample’s population versus previous studies sample populations.

Description
Herpes simplex virus 2 (HSV-2) is one of the most common sexually transmitted infections (STI), affecting over 267 million women worldwide. HSV-2 causes a chronic, latent infection that increases the risk for acquisition with other STI, including HIV. Currently, there is no vaccine against HSV-2 and novel anti-viral treatments are needed. IL-36γ is a newly characterized cytokine that has been shown to play a role in inflammation and be upregulated in response to microbial infection and tissue damage. We have shown that IL-36γ is expressed in the female reproductive tract (FRT) and is upregulated by HSV-2 infection in vitro and in vivo. IL-36γ in turn induces production of proinflammatory cytokines and chemokines in human vaginal epithelial cells (VEC) that can aid in immune cell recruitment. We hypothesize that IL-36γ is a key regulator of mucosal inflammation in the FRT and functions to limit HSV-2 infection. We have demonstrated that IL-36γ treatment prior to infection protects against HSV-2 replication, disease severity, and promotes survival in a lethal mouse model. Thus, the objective of this study is to understand the mechanisms whereby IL-36γ inhibits HSV-2 replication. To understand the impact of IL-36γ on the HSV-2 lifecycle, we pretreated VEC with IL-36γ and evaluated viral titer during virus attachment and entry, replication, and cell-to-cell spread by plaque assay. Pretreatment with IL-36γ 4h prior to infection did not significantly reduce viral titers in VEC monolayers relative to untreated groups. This suggesting that IL-36γ may play a more significant role in immune cell recruitment during HSV-2 infection. To test this, FRT tissue samples from HSV-2 infected IL-36γ -/- and WT mice were analyzed by histochemistry to characterize immune cell recruitment. No clear pattern was determined for tissue samples in which cell clusters were observed and cell type within recruited clusters was unable to be identified at the current magnification. As these projects continue, the data will aid in elucidating the mechanism and level to which IL-36γ impacts HSV-2 infection in human VEC and FRT models.

Description
In response to a national call within STEM to increase diversity within the sciences, there has been a growth in science education research aimed at increasing participation of underrepresented groups in science, such as women and ethnic/racial minorities. However, an underexplored underrepresented group in science are religious students. Though 82% of the United States population is religiously affiliated, only 52% of scientists are religious (Pew, 2009). Even further, only 32% of biologists are religious, with 25% identifying as Christian (Pew, 2009; Ecklund, 2007). One reason as to why Christian individuals are underrepresented in biology is because faculty may express biases that affect students' ability to persist in the field of biology. In this study, we explored how revealing a Christian student's religious identity on science graduate application would impact faculty's perception of the student during the biology graduate application process. We found that faculty were significantly more likely to perceive the student who revealed their religious identity to be less competent, hirable, likeable, and faculty would be less likely to mentor the student. Our study informs upon possible reasons as to why there is an underrepresentation of Christians in science. This further suggests that bias against Christians must be addressed in order to avoid real-world, negative treatment of Christians in science.

Description
In 2015, the World Health Organization cited antibiotic resistance as one of the greatest current challenges to global public health. A major driver of the evolution of antibiotic resistance is the overuse and misuse of these drugs. While antibiotic stewardship, education campaigns, and health policy attempt to limit drug use globally, public understanding of antibiotic resistance and its consequences are lacking. The goal of this study is to analyze the social and cultural influences of antibiotic knowledge and usage behavior. Over a three-month period, I interviewed 211 laypersons in Guatemala, Spain, the Netherlands, India, South Africa, and New Zealand to understand their ideas, perceptions, and behaviors regarding antibiotics and compared results across countries. While an overall consensus across countries does exist, I found significant differences between low and high income countries as well as between low and high antibiotic consumption countries. Additionally, I found that having increased public health knowledge is related to lower antibiotic "risky" behavior. These results help contextualize national data on antibiotic consumption and resistance by illustrating relationships between access, beliefs, and consumption patterns within populations. The results also inform the development of community and culture specific educational campaigns regarding antibiotic resistance.

Description
Past studies have shown that exercise in the form of high intensity interval training (HIIT) is the "ideal form of exercise to improve health and performance without overstressing the immune system" (Fisher et. al, 2011, p. 5). Additionally, HIIT has been found to promote cardiovascular health and immunity (Fisher et. al, 2011). The proposed study will evaluate the neuropsychological effects of HIIT on breast cancer patients undergoing anthracycline-based chemotherapy. The intervention group (n = 17) will receive a HIIT protocol concurrent with chemotherapy treatment. There will also be a control group (n= 17) to compare the effects of the intervention. Breast cancer survivorship is often ridden with various health and mental problems, the implementation of HIIT procedures could help to reduce these issues. It is expected that knowledge from this study will be useful in the healthcare setting to benefit breast cancer patients. This study will uniquely add to the limited research base by introducing an intervention for neuropsychological declines in breast cancer patients.

Description
Abstract The BIO 189 Life Sciences Career Paths course is a seminar course that is intended to acclimate incoming freshmen into the School of Life Sciences (SOLS). While there are instructors who organize and present in the class, upper division undergraduate students are primarily responsible for facilitating lectures and discussions and mentoring the freshmen. Prior research has demonstrated that the mentor-mentee relationship is a very important predictor of success and retention within all university first-year programs. While past studies focused on the student mentor-mentee relationships, there is limited research that measures student satisfaction within freshmen seminar courses, especially in areas of science, technology, engineering, and mathematics (STEM). The purpose of this project is to survey students about their perception of the BIO 189 course. The effort of the project is on pre-health students, as they initiate their undergraduate careers and attempt to achieve acceptance into professional school four years later. Analysis of Likert scale surveys distributed to 561 freshmen revealed that students with an emphasis on "medicine" in their majors preferred a BIO 189 course geared to pre-health interests whereas students seeking an emphasis on research (ecology and cell biology/genetics) sought a BIO 189 course focused on internship and employment opportunities. Assessment of the mentor-mentee relationship revealed that students (n = 561) preferred one-on-one meetings with mentors outside of class (44%) compared to those who preferred interaction in class (30%). A sizable 61.68% of students (n = 548) were most concerned with attaining favorable GPAs, highlighting strong emphasis on academic performance. Overall, 61% of respondents (n = 561) expressed satisfaction with SOLS resources and involvement opportunities, which was hypothesized. These results give substantial insight into the efficacy of a first-year success seminar-mentoring program for college freshmen in STEM.
