According to the CDC, diabetes is the 7th leading cause of death in the U.S. and rates are continuing to rise nationally and internationally. Chronically elevated blood glucose levels can lead to type 2 diabetes and other complications. Medications can be used to treat diabetes, but often have side effects. Lifestyle and diet modifications can be just as effective as medications in helping to improve glycemic control, and prevent diabetes or improve the condition in those who have it. Studies have demonstrated that consuming vinegar with carbohydrates can positively impact postprandial glycemia in diabetic and healthy individuals. Continuous vinegar intake with meals may even reduce fasting blood glucose levels. Since vinegar is a primary ingredient in mustard, the purpose of this study was to determine if mustard consumption with a carbohydrate-rich meal (bagel and fruit juice) had an effect on the postprandial blood glucose levels of subjects. The results showed that mustard improved glycemia by 17% when subjects consumed the meal with mustard as opposed to the control. A wide variety of vinegars exists. The defining ingredient in all vinegars is acetic acid, behind the improvement in glycemic response observed with vinegar ingestion. Vinegar-containing foods range from mustard, to vinaigrette dressings, to pickled foods. The benefits of vinegar ingestion with carbohydrates are dose-dependent, meaning that adding even small amounts to meals can help. Making a conscious effort to incorporate these foods into meals, in addition to an overall healthy lifestyle, could provide an additional tool for diabetics and nondiabetics alike to consume carbohydrates in a healthier manner.

Description
The development of the Diabetic Physiological state is influenced by the Receptor for Advanced Glycation End Products (RAGE). This receptor was discovered in 1992, and the accumulation of research on this subject has been extensive. Structural characterization studies of the RAGE protein have shown that it is a transmembrane protein that binds a number of different motile ligands. The diversity of ligands that can attach to the binding domain is the primary factor that allows for RAGE to exhibit its wide-range effects on host cells. Two different studies were completed: one study dealt with the role of IAPP in beta cell death, and the second study was related to RAGE influence on cardiomyocytes and, more specifically, it was related to cardiac cell death. After the completion of the two studies, a comprehensive report was written for each topic. The two papers were merged into a single document. Molecular studies are important for understanding the underlying mechanisms that motivate pathophysiological presentation. In addition to a molecular understanding of the development of diabetes, a clinical research study was completed through the examination of appropriate literature sources. This clinical aspect allowed for the progression of different phases in the research process. A relationship between vinegar and lower plasma glucose was found. The exact mechanism behind this relationship will be studied in the future.

Description
Background: The prevalence of childhood obesity has disproportionately affected Latino youth. This increase in obesity is seen with an increased incidence of Type 2 Diabetes. Objective/Hypothesis: The objective of this study was to determine the effects of a community based lifestyle intervention, which encompassed nutrition education and physical activity, on diabetes risk in pre-diabetic Latino adolescents. Diabetes risk was assessed using pancreatic beta cell function as measured by proinsulin: insulin ratio. It was hypothesized that reductions in added sugar intake and reductions in saturated fat intake will be associated with improved beta cell function as measured by proinsulin: insulin ratio. Study Design/Participants: In this quasi-experimental study design, n=17 pre-diabetic Latino adolescents between the ages of 14-16 participated in a lifestyle intervention. Methods: Anthropometric measurements (weight, height, waist circumference, BMI) and body composition (body %) were determined for all participants at baseline and post intervention. Fasting proinsulin (PI), fasting insulin (I) and 2hr-OGTT were also determined. Dietary intake was measured using the Block Kids Food Screener for kids ages 2-17y (2007). The intervention consisted of nutrition education classes and physical activity sessions for 12 weeks. Results: We found significant decreases in body fat % following the intervention. There were no significant decreases in fasting insulin. Proinsulin significantly decreased. However we did no see a significant change in PI/I (p= 0.003). Dietary behaviors of added sugar (p=0.03) and saturated fat (p=0.04) showed significant decreases. No significant associations were found between changes in added sugar to improvements in beta cell function, r=0.072, p-value= 0.7. We also did not observe significant associations between reductions in saturated fat intake and improvements in beta cell function, r=0.152, p-value =0.6. Conclusions: We concluded that a 12-week lifestyle intervention resulted in significant changes in dietary behaviors. These changes were not however associated with improvements in beta cell function.

Description
This study examines cognitive and motor function in adolescents with Down syndrome (DS) following an 8-week assisted cycling therapy intervention. Forty-four participants were randomly assigned to three groups consisting of an assisted cycling (AC) (i.e., exercise accomplished through the use of a motor), a voluntary cycling (VC) (self-selected cadence), and a no cycling (NC) control group. Both ACT and VC groups rode a stationary bicycle for three 30-minute sessions a week, for a total of eight weeks. Participants completed cognitive testing that assessed information processing and manual dexterity at the beginning and at the end of the 8-week intervention. Consistent with our hypothesis, the results showed that information processing and manual dexterity improved following 8 weeks of cycling for the ACT group. These results were not seen for individuals in the voluntary and non-exercise groups. Our results suggest that assisted cycling therapy may induce permanent changes in the prefrontal cortex in adolescents with DS.

Description
Creative adventurers are a modern artistic subculture defined by aesthetic individualism and rugged outdoor practicality. Contemporary photographers and videographers who live an active outdoor lifestyle place significant demands on their shoes and feet wherever they work. As a result of the increasing growth of photo based social media, part of producing creative content in this field involves artists interacting directly with their favorite brands through "product tagging" and other means of rapid networking. This energetic atmosphere of creativity and brand engagement presents a unique opportunity to introduce a footwear product specifically made for the brand-conscious visual artist. A collaborative shoe project between a major footwear brand such as Nike or Adidas and a major camera brand such as Canon or Sony is a unique and exciting way to meet the functional and aesthetic demands of this population.

Description
This study examines the relationships between the success of Instagram health and fitness influencers and the images they share. As social media continues to grow as a source of information and interconnectedness, the sway influencers hold over their followers and potential consumers grow too. The success of these influencers in gaining followers, motivating opinions and achieving an aesthetic physique, result in monetary gain. On the media site Instagram, influencers with one million followers can garner over $50,000 per sponsored post. Specifically, the research focuses on four Instagram influencers who have over 200,000 followers. The subjects, Amanda Bucci, Nikki Blackketter, Maxx Chewning and Christian Guzman, were selected based on their popularity within the weight lifting community. Together, these influencers have over 400 million followers on Instagram. The study analyzed 32 photos sourced from the influencer's Instagrams. Of the 32 images, 16 were selected as branded content and 16 were selected as candid content. These images were then coded to answer the following research questions: (1) is there a pattern in the visuals weight lifters share, (2) is there a difference between branded or candid content, (3) how do these similarities or lack thereof influence number of Instagram followers and financial success, and (4) what physical dimensions contribute to a weight lifter's success on Instagram? This study uses content analysis to understand the symbolic meaning of texts and visuals. With the findings showing recurrent themes between (1) posture of subject, (2) use of brand affiliation and (3) professional grade photography, we confirm that bodily capital, sponsorship and authenticity are successful tactics used by influencers to generate a following.

Description
The objective of this study was to evaluate and compare the content of nutrition marketing materials within the cafeterias of schools in Central Arizona. By collecting photographs of marketing material from three elementary schools, one K-8 school, three middle schools and three high schools, 59 pieces of nutrition marketing were gathered. The schools chosen were a convenience sample and selected from schools that were already participating in ASU' s School Lunch Study. The photographs were sorted by grade level and then coded quantitatively and qualitatively for their purpose, visual components, strategies used and relevance. Results from this novel study provided insight into prevalence, size, textual content, educational content, strategies for fruit and vegetable marketing, messaging and overall design of existing nutrition marketing within the sample schools. This study found that the prevalence of nutrition marketing within all school cafeterias appeared to be low, particularly within elementary and middle schools. Diverse types of messaging were present among elementary, middle and high schools and a variety of appeals were utilized with little consistency. Many of the strategies used in the nutrition marketing appeared disconnected from the population it was intended to appeal to. Educational components were notably lacking within middle school cafeterias but were often effectively integrated into high school nutrition marketing. The results are unique to this population, and further research is required to evaluate the content of existing nutrition material on a larger scale, so efforts can be made to improve the persuasiveness of nutrition marketing in promoting fruit and vegetable consumption.

Description
The purpose of this cookbook is to provide pre-diabetic, type 1 and type 2 diabetics with a foundation of recipes. These recipes have been created with the intent of regulating inflammation which can be caused by such metabolic abnormalities. I want to educate patients who suffer from these conditions that there are several ingredients that work alongside their condition rather than feeling that they are limited to foods and recipes. I want to increase patients moral and self-efficacy to explore and work with new ingredients. These series of recipes should be used as a guide to trying new foods however patients should know that they are able to add their own ingredients that are suitable to their liking or condition.

The purpose of this study was to examine the association between VLDL and diabetes risk factors, and the impact of a lifestyle intervention on VLDL levels in obese Latino youth. Participants (N=160) in this study were taken from a lager diabetes prevention program for Latino adolescents (Age=14.8±0.8 years, BMI=98.2±1.4). Youth participated in a 12-week lifestyle intervention that included physical activity (60 minutes, 3x/week) and nutrition education sessions (60 minutes, 1x/week) that were delivered to families at the downtown Phoenix YMCA. Primary outcomes included VLDL and diabetes risk factors including fasting and 2-hour glucose and insulin which were measured at baseline and 12-weeks post-intervention. Baseline VLDL levels were significantly correlated with fasting insulin (r =.270, P<0.01) and youth who were more insulin resistant displayed higher VLDL levels compared to youth who were less insulin resistant derived from fasting insulin levels (M=29.8±14.7 mg/dl vs. M=21.6±9.6 mg/dl, P<0.01). In total, 77 participants completed the lifestyle intervention. At post-intervention, VLDL levels were significantly reduced (M=26.0±13.3 mg/dl to M=23.3±11.6 mg/dl, P=0.02). Culturally-grounded, community-based, family-focused lifestyle interventions are a promising approach for reducing cardiovascular disease risk factors in high-risk youth at risk for diabetes.
