Abstract
OBJECTIVE Providing video recordings of lecture material may enhance student flexibility, but does it alter attendance or influence their grade? This project assessed the extent and purpose of video usage by students and evaluated their impact on course performance within first-year basic science courses in a chiropractic curriculum. METHODS All first-year students enrolled at a chiropractic college based in the United States were invited to complete a retrospective survey regarding video usage, attendance, and study behaviors for basic science courses they were enrolled during the previous term. Grades were third-party obtained for each consenting student. Statistical analysis included descriptive statistics and independent t tests for each course. Effect size using Cohen's d was calculated for all statistically significant courses (p < .05). RESULTS Overall, 260 students completed the questionnaire assessing 18 courses in total. The perceived helpfulness of video recordings was associated with heavier usage, primarily to study for exams. Shorter summary videos were preferred by 78% of students over full lecture recordings. Use of videos to replace lectures increased from 21.9% to 53.2% in first through third trimester, respectively. Video use in Neuroanatomy I, Neuroanatomy II, Gross Anatomy II, Organ Histology, and Endocrinology were associated with lower exam scores and overall grades (p < .05), yielding moderate to large effect sizes. CONCLUSION Videos were used < 1 hour per week, primarily to study for exams. When used as a study tool, video use decreased course performance. Rewatching videos to prepare for exams may be mistaken for mastery of material.

Abstract
OBJECTIVE Test anxiety is a debilitating disorder that can impair cognitive performance and affect academic success. Aromatherapy is commonly used for relaxation therapy. The primary aim of the study was to determine if nasal inhaler aromatherapy, utilizing a blend of rosemary and lavender essential oils, could be a useful strategy to reduce testing anxiety in students. METHODS This study recruited first trimester chiropractic students enrolled in both Neuroanatomy I and Biochemistry I. A randomized crossover design was utilized over 2 study days during final exams, with a 2-day wash-out period. Participants were randomly assigned into groups based on results of test anxiety analysis. On each day, students were given a nasal inhaler with either an aromatherapy blend of lavender and rosemary essential oils or distilled water as the control. Students completed pretest surveys and posttest surveys to rate their anxiety levels. Paired sample t-tests were performed to determine group differences in test anxiety. Both intention-to-treat and per-protocol analyses were conducted. RESULTS Forty-five students were randomly assigned into the study, whereas only 38 completed per-protocol. Between group comparisons showed no statistically significant difference between change in anxiety scores between aromatherapy and control for both intention-to-treat (p =.10) and per-protocol (p =.07). CONCLUSION Use of personal inhalers and aromatherapy diffusers were not shown to reduce test anxiety in a chiropractic population under high-stakes examination. Other options should be explored for future research.

Abstract
OBJECTIVE Up to 85% of college students experience test anxiety, which may contribute to decreased academic performance. The purpose of this study was to assess the feasibility of recruiting chiropractic students for a randomized trial involving aromatherapy for anxiety reduction. METHODS This study enrolled chiropractic students who were randomly assigned to separate rooms during a biochemistry test. Waterless diffusers dispersed a lemon and rosemary blend of essential oils in the experimental room and water in the control room. Students completed pretest surveys rating current and general anxiety. Posttest surveys included rating current anxiety. Analysis of covariance (ANCOVA) was preformed to determine within- and between-group differences for current anxiety. Feasibility was the primary aim, and the statistical significance of anxiety test scores between rooms was the secondary aim. RESULTS Sixty-four students were included in the study. The feasibility of research methods was noted for adherence to the study protocol (informed consent, randomization, and survey distribution and completion) and resource allocation. Design improvements are required in recruitment methods, follow-up surveys, and intervention blinding. ANCOVA for between-group comparisons showed no statistically significant difference between groups' pre- and posttest anxiety scores (p = .22). Two reported side effects, eye and sinus irritation, could not be attributed to treatment group. Most students were willing to use aromatherapy for test anxiety in the future. CONCLUSION We demonstrated feasibility in conducting a randomized study to measure the influence of aromatherapy on test anxiety in chiropractic students. A powered, randomized study is needed to determine if aromatherapy may be effective in reducing test anxiety.

Abstract
Background: The study focused on perceptions of older adults toward the healthcare processes they experienced during a clinical trial for back pain that involved family medicine residents and licensed chiropractors. Methods: Individual semi-structured interviews were conducted with 115 older adults after a 12-week, 3-arm, randomized controlled trial. Two researchers conducted thematic analysis with inductive coding using qualitative software to identify participants’ salient experiences of the doctor–patient relationship, healthcare process, and collaboration between study providers. Investigators categorized thematic codes within an existing framework of clinical excellence in primary care. Results: Participants emphasized provider communication and interpersonal relationships, professionalism and passion for patient care, clinical and diagnostic acumen, and skillful negotiation of the health-care system. Older adults also described the importance of interdisciplinary collaboration and their preferences for receiving hands-on treatments for musculoskeletal conditions. Conclusion: These older adults valued doctors who communicated clearly and spent time listening to their concerns. Many participants appreciated clinicians who supported an active role for patients in their health-care and who provided touch-based care for musculoskeletal conditions.

Abstract
OBJECTIVE We aimed to identify chiropractic students' cooking skills, perceptions of healthy eating, and influence of prior nutrition training on dietary intake. METHODS Two cohorts of incoming graduate students were surveyed to assess nutritional training prior to matriculation, perceptions of healthy eating behaviors, cooking skills, current dietary intake, and barriers to healthy eating. Using independent t tests, correlations, and descriptive statistics, data from the cohorts were assessed. RESULTS The response rate was 88.7% (n = 178). Nutritional training significantly increased perception of nutritional knowledge and confidence in giving nutrition advice. Completion of at least 1 college nutrition course was associated with nearly double students' weekly fatty fish intake. Males were more likely to eat animal protein, and females preferred desserts. Modeling a healthy diet for future patients was rated as being important, yet most students consumed diets consistent with the typical American diet. The leading barriers to healthy eating included lack of time and money. CONCLUSION Similar to students in other healthcare professions, incoming chiropractic students wish to model healthy behaviors but fail to apply their knowledge and attitudes to their own dietary intakes due to common barriers.

Abstract
OBJECTIVE Technology-enhanced learning is on the rise within healthcare education. This pilot study evaluated the relationship between the use of online review videos and students' performance and satisfaction in gross anatomy. METHODS For this quasi-experimental study, we developed a series of online gross anatomy review videos, and surveyed students enrolled in a doctor of chiropractic program regarding use of the videos and their attitudes towards using the videos. Ordinal regression was used to evaluate the relationship between students' video use and course performance and the Mann-Whitney U test was used to determine whether there was a difference in course performance between students who did and did not report using the review videos. RESULTS We received 143 responses to our survey, resulting in a 73.3% response rate. Most students (71%) had engaged with the online review videos. No significant differences in course performance were detected between students who did and did not report using the videos. Many students (82%) reported the review videos as being "helpful" and 73% perceived them as "an enjoyable way to study." CONCLUSION While chiropractic students perceived a series of online gross anatomy review videos as being an enjoyable and helpful way to study, engagement with this form of technology-enhanced learning did not have an impact on their overall gross anatomy course performance.

Abstract
OBJECTIVE A chiropractic pediatric specialist often encounters novel clinical findings not reported currently in the literature. This project matched board certified chiropractic pediatric specialists with a mentor experienced in scientific writing to co-author a research paper to add to the literature base available on chiropractic pediatric practice. METHODS Clinicians who had received their Diplomate in Clinical Chiropractic Pediatrics and mentors in scientific writing were teamed up. Two surveys were conducted to collect quantitative data, and focus groups were held to gather qualitative data about the overall experience of the mentor and mentee (clinicians) participating in the study. The first survey was sent to the clinicians to gather information about their research idea and their experience in research. The second survey was conducted upon project completion by clinicians and mentors. A project wiki was used as a communication strategy. RESULTS Ten reports were submitted by authorship teams. Time spent on this project was an average of 58 hours by clinicians and 36 hours by the mentors. Mentors aided by adding content material, editing manuscripts, and educating the clinicians in the art of writing a paper. Improvements for this project included clearer mentoring guidelines and not using the wiki as a communication venue. CONCLUSION The project ultimately fulfilled the goal of using a mentorship model to facilitate scientific writing education and ease the anxiety of authoring a first publication. The overall experience was "good"; however, there are opportunities for improvement.

Abstract
Chocolate storage is critical to the quality of the final product. Inadequate storage, especially with temperature fluctuations, may lead to a change in crystal structure, which may eventually cause fat bloom. Bloom is the main cause of quality loss in the chocolate industry. The impact of various storage conditions on the flavor quality of dark chocolate was determined. Dark chocolate was stored in different conditions leading to either fat or sugar bloom and analyzed at 0, 4, and 8 weeks of storage. Changes in chocolate flavor were determined by volatile analysis and descriptive sensory evaluation. Results were analyzed by analysis of variance (ANOVA), cluster analysis, principal component analysis (PCA), and linear partial least-squares regression analysis (PLS). Volatile concentration and loss were significantly affected by storage conditions. Chocolates stored at high temperature were the most visually and texturally compromised, but volatile concentrations were affected the least, whereas samples stored at ambient, frozen, and high relative humidity conditions had significant volatile loss during storage. It was determined that high-temperature storage caused a change in crystal state due to the polymorphic shift to form VI, leading to an increase in sample hardness. Decreased solid fat content (SFC) during high-temperature storage increased instrumentally determined volatile retention, although no difference was detected in chocolate flavor during sensory analysis, possibly due to instrumental and sensory sampling techniques. When all instrumental and sensory data had been taken into account, the storage condition that had the least impact on texture, surface roughness, grain size, lipid polymorphism, fat bloom formation, volatile concentrations, and sensory attributes was storage at constant temperature and 75% relative humidity.

Abstract
Our previous studies suggested that after a median lethal dose (LD50) of endotoxin, cardiac contractility was depressed in nonsurviving dogs. The canine cardiovascular system is unlike humans in that dogs have a hepatic vein sphincter that is susceptible to adrenergic stimulation capable of raising hepatic and splanchnic venous pressures. We retested the hypothesis that lethality after endotoxin administration is associated with cardiac contractile depression in pigs, because the hepatic circulation in this species is similar to that of humans. We compared cardiac mechanical function of pigs administered a high dose (250 micrograms/kg) or a low dose (100 micrograms/kg) endotoxin by use of the slope of the end-systolic pressure-diameter relationship (ESPDR) as well as other measurements of cardiac performance. In all the pigs administered a high dose, ESPDR demonstrated a marked, time-dependent depression, whereas we observed no significant ESPDR changes after low endotoxin doses. The other cardiodynamic variables were uninterpretable, due to the significant changes in heart rate, end-diastolic diameter (preload), and aortic diastolic pressure (afterload). Plasma myocardial depressant factor activity accumulated in all endotoxin-administered animals, tending to be greater in the high-dose group. In this group, both subendocardial blood flow and global function were depressed, whereas pigs administered the low dose of endotoxin demonstrated slight, but nonsignificant, increases in flow and function. These observations indicate that myocardial contractile depression is associated with a lethal outcome to high doses of endotoxin. One possible mechanism for this loss of contractile function may be a relative hypoperfusion of the subendocardium.

Abstract
We studied canine left ventricular contractile performance following splanchnic artery occlusion (SAO) shock. We evaluated contractile performance by analyzing the left ventricular end systolic pressure-diameter relationship (sigma ES) because we have previously shown that sigma ES is independent of large changes in preload, afterload, and heart rate but sensitive to changes in ventricular contractility. Following release from 2 hours of SAO, seven dogs survived, five expired immediately, and ten expired between 0.5 and 3.5 hours (termed nonsurvivors, [NS]). The NS dogs exhibited slight tachycardia, slight increase in total peripheral resistance, marked decreases in +dP/dt, cardiac output, arterial blood pressure, stroke volume, and stroke work. Ventricular performance (sigma ES) declined with time following SAO release in the nonsurviving dogs; in contrast, surviving animals exhibited an augmentation of sigma ES during SAO and following SAO release. Sham dogs exhibited no time-dependent changes in sigma ES. The dogs that expired immediately following SAO release exhibited a precipitous decline in sigma ES from 43.0 +/- 9.0 to 23.0 +/- 4.8 mm Hg/mm within minutes of SAO release. We analyzed these data by Cox multiple regression analysis to determine the major covariates of survivability. The analysis revealed that sigma ES at the midpoint in time between SAO release and death was best correlated with the survival function. These results suggest that cardiovascular collapse of SAO shock is associated with an early and sustained loss of ventricular contractility.
