Chronic illness such as strokes, heart disease and diabetes all rank among the leading causes of death in the United States. Recently, fasting has gained popularity as a means of preventing and treating chronic illness. PURPOSE: Fasting produces multiple beneficial physiological responses that have been shown to aid in chronic disease prevention, one of which is observed in relation to incretin hormones such as glucose-dependent insulin tropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1). These incretin hormones are released by the gut to augment the secretion of insulin to regulate postprandial glucose levels. During a fast, the decrease in incretin hormones, and resultant insulin levels can aid the body to regain insulin sensitivity. This can lead to more effective blood glucose management and chronic illness prevention. The purpose of the study was to determine the impact of an acute 24-hour fast started with either a high fat (HF) or high carbohydrate (HC) meal on plasma GIP and GLP-1. METHODS: Subjects were over the age of 55, had a BMI equal to or greater than 27, and had no diagnosed metabolic disorders or some other disqualifying medical issues. Using a randomized crossover design, each participant performed two 24-hour fasts. One fast beginning with a high carbohydrate meal and the other a high fat meal, both of equal calories. Venous blood draws were taken at 0, 1, 24, and 48 hours. RESULTS: GIP and GLP-1 (P < 0.001) were both elevated 1 hour after consuming the pre-fast meal in both conditions. In addition, both GIP (P = 0.0122) and GLP-1 (P = 0.0068) were higher in the high fat condition compared to the high carbohydrate condition at 1 hour. There were no significant differences between conditions for either GIP or GLP-1 at any other time point. CONCLUSION: As expected, both incretin hormones spiked postprandially. We did find that GIP and GLP-1 levels were significantly higher at 1-hour postprandial for the HF meal compared to the HC meal. This could give evidence to show how macronutrient levels can affect incretin secretion and alter sensitivity to insulin. However, the impact of the pre-fast meal on GLP-1 and GIP did not persist throughout the fast.

Authors: Leila Moore, Marin Farnsworth. Mentors: Tyson Harmon. Insitution: Brigham Young University. Background:Facial expressions are crucial for understanding human emotions in communication. Coding and quantifying these expressions, however, have often been subjective, leading to issues with reliability and consistency (Kring and Sloan, 2007). To address this, we have modified the Facial Expression Coding System (FACES) protocol (Kring and Sloan, 2007), which traditionally relies on subjective interpretation. Our modified protocol employs a more objective approach by quantifying facial expressions based on the counting of facial units (e.g., eyes, corners of the mouth, eyebrows, and teeth). Each intensity rating corresponds to a certain number of facial units. For example, an expression involving one facial unit would receive an intensity rating of one whereas an expression involving two units would receive an intensity rating of two. Multiple studies have found that women are more emotionally expressive than men overall when considering gestures, body language, facial expressions, and tone of voice (Ashmore, 1990; Brody & Hall, 1993; Hall, 1984). Rather than focusing on overall emotional expressiveness, though, the present study aims to understand how gender impacts the production of emotional facial expressions specifically. Method:The proposed study aims to compare the frequency and intensity of facial expressions produced by men versus women when recounting personal narratives. Participants. Video footage from participants with and without aphasia producing personal narrative discourse will be obtained for equal numbers of male and female participants. Samples will include two personal narratives in response to prompts from the interviewer. The first prompt is to speak of an experience the participant has had with illness/injury/stroke, and the second prompt is to talk about an important event that has happened in their life. Procedure. A modified FACES protocol will be used to code facial expressions in videos obtained from AphasiaBank. The coding process is conducted with the audio muted to help eliminate distractions. The modified FACES protocol includes specific, operationalized criteria for what qualifies as a facial expression. This protocol does not include coding non-facial gestures or eye movements. However, we do take into account the narrowing and widening of eyes in addition to instances when the eyes are opened or closed with intention. A critical question we ask during coding is whether the facial expression conveys emotional content. We have established standards for intensity ratings and will outline how we arrived at these standards, as well as the distinctions between intensity ratings one, two, three, and four. The analysis process includes establishing a baseline expression for each participant and coding for 20 minutes before taking a break to maintain energy and productivity and to ensure accuracy in data collection. Additionally, secondary coding and a final pass for gestalt ratings are performed to ensure comprehensive analysis.Data Analysis. To address our research questions, we will conduct a comprehensive analysis, focusing on our participants' facial expressiveness during personal narrative storytelling. The analysis will involve quantifying the frequency of facial expressions exhibited by the participants. Additionally, we will consider the valence of these expressions, distinguishing between positive and negative emotional content. We will also assess the intensity of facial expressions by counting the number of facial units engaged during each expression. This examination of facial data will allow us to discern not only the prevalence of expressions but also emotional content and intensity, ultimately providing a more in-depth understanding of the gender differences in non-verbal communication during personal narratives.Anticipated Results:Our study aims to explore if there is a statistically significant difference in the quantity, valence, and intensity of facial expressions between men and women. By using a standardized approach for measuring emotional facial expression production, we hope to shed light on the nuances of non-verbal communication during personal narratives and contribute to a better understanding of gender differences in emotional expression. Consistent with previous research, we anticipate that females will produce more frequent and intense emotional facial expressions than males (Ashmore, 1990; Brody & Hall, 1993; Hall, 1984).References:Ashmore, R.

IntroductionPersonalized cancer care requires molecular characterization of neoplasms. While the research community accepts frozen tissues as the gold standard analyte for molecular assays, the source of tissue for all testing of tumor tissue in clinical cancer care comes almost universally from formalin-fixed, paraffin-embedded tissue (FFPE). Specific to genomics assays, numerous studies have shown significant discordance in genetic information obtained from FFPE samples and cryopreserved samples. To explain the discordance between FFPE samples and cryopreserved samples, a head-to-head comparison between FFPE and cryopreserved tissues was performed to analyze the DNA yield, DNA purity, and DNA quality in terms of DNA length.MethodsHuman (n = 48) and murine tissues (n = 10) were processed by traditional formalin fixation and paraffin embedding or placed in cryovials containing HypoThermosol solution. 19 human-matched samples were included. These cryovials were cooled to -80°C slowly and stored in liquid nitrogen until the time of the study. DNA was extracted using the same protocol for both tissue types except that tissues embedded in paraffin were first dewaxed using a xylene substitute followed by a multistep rehydration protocol using ethanol and water. Samples were weighed and calibrated to have the same starting mass. After the column purification, samples were eluted in 20 µL and concentration and purity were measured on a Nanodrop. Purity was determined by calculating the 260/280 ratio. DNA fragment length was measured on an Agilent Fragment Microelectrophoresis Analyzer.ResultsGraded amounts of tumor tissue (5- >50 mg) were used to determine the lowest starting material needed to extract 40 ng/mg of DNA. The average for both sample types reached the minimal threshold of 40 ng/mg. However, 74% of FFPE specimens failed to meet the minimum 40 ng/mg, whereas only 21% were below the threshold in the cryopreserved samples (Figure 1). In the cryopreserved group, the average DNA yield was 222.1 ng/mg, whereas 52.8 ng/mg was obtained from FFPE tissue. For DNA purity in cryopreserved tissues, the 260/280 ratio range was 1.09-2.13 with a mean of 1.79. The 260/280 ratio range in FFPE tissues was 0.85-2.76 with a mean of 1.65 (Figure 2). The DNA Quality Number(DQN) is a measurement of DNA fragment length and the percentage that exceeds the threshold of 300 bp. For FFPE, the DQN was 4.4 compared to a DQN of 9.8 for the cryopreserved samples (Figure 3). Setting a higher threshold of DNA length to 40,000 bp and measuring the area under the curve (AUC), it was observed that cryopreserved samples were 9-fold higher in fragments greater than 40,000 bp (Figure 4).ConclusionsCryopreserved cancer tissue provides superior quality assurance measurements of DNA over FFFPE. Treatment decisions based on molecular results demand accuracy and validity. The pathology community should support efforts to cryopreserve cancer biospecimens in the clinical setting to provide valid molecular testing results. The automatic pickling of tumor specimens in formalin is no longer an acceptable default.

BACKGROUND: Recent studies have shown that there are differences bilaterally in the cross sectional area of the patellar tendon for lead vs non lead extremities of athletes. Yet, little research can be found as to whether there is a difference that develops over one’s lifetime between the stiffness of the patellar tendons in the dominant vs non-dominant legs. Reliability has not yet been established for elastography in the patellar tendons, so we are continuously striving to gather more reliable data on shear-wave elastography of the patellar tendon. PURPOSE: The aim of this study was to assess whether there is a difference in the average patellar tendon stiffness as measured by ultrasound elastography using a pad vs no pad and differences between self reported non-dominant vs dominant knee of senior athletes over the age of 50. Dominance taken as reported in a modified KOOS (Knee Injury and Osteoarthritis Outcome Score) survey. METHODS: Data was collected from 15 active, senior aged volunteers at the Huntsman World Senior Games in St George, Utah, 2023. All subjects (mean age= 67.29 ± 6.26 yrs, height=175.44 ± 8.18 cm, weight=87.40 ± 12.21 kg) signed an approved consent and completed a modified KOOS survey. Following, they were seated on a table, with their backs against the wall directly behind them. They were seated so that their lower legs were hanging off of the table in a relaxed position. The patellar tendon was then imaged with a long axis view using ultrasound elastography. ANALYSIS: All data were analyzed using JMP ver16.2 with a repeated measured analysis of variance (ANOVA) to determine if differences existed between pad and no pad and between dominant and non- dominant legs. RESULTS AND CONCLUSION: There was a significant difference between (p=.0423) pad and no pad patellar tendon measurements, but no significant difference when comparing sides combined with pad and no pad, between dominant and non-dominant legs, although a trend for significance did exist, and we suspect that with more subjects analyzed, we will get more significance.

In the dynamic game of professional football, where split-second decisions and explosive movements often determine the outcome, players train all year round for optimal athletic performance. Paramount to this performance are the hamstring muscles including the semimembranosus (SM), semitendinosus (ST), and both the long and short head of the biceps femoris (BFLH and BFSH). They play pivotal roles in sprints, agility, jumping, and overall lower-body strength. Because of the critical nature of the hamstrings during functional activity, this study sought to determine which of these three muscles contributes the most to eccentric hamstring strength. Recognizing the correlation between muscle volume and muscle strength, this study compared maximal eccentric hamstring strength with the proportion of each isolated hamstring muscle's volume relative to the total hamstring muscle group volume. Doing so would identify which specific muscle contributes the most to eccentric hamstring strength. This study incorporated 74 male, collegiate football players representing all positions on the team. Maximal strength was assessed through Nordic hamstring curls and overall muscle volume was quantified using magnetic resonance imaging (MRI). Our results show no correlation (R^2<0.2) between maximal force output and proportional muscle volume for the ST, and the BFSH. Additionally, the correlations for these muscles were not statistically significant (P>0.05). The SM muscles had a weak negative correlation (R^2= -0.25) with eccentric hamstring strength that was statistically significant (P = 0.03). The BFLH proportional volume was positively weakly correlated (R^2= 0.22) with eccentric hamstring strength. This correlation was statistically non-significant (P = 0.06). This information shows that no hamstring muscle contributes more to eccentric hamstring strength than any other. Knowledge of this can be invaluable for clinicians and researchers to design comprehensive strength training programs that enhance the collective strength of the entire hamstring muscle group, ultimately optimizing the performance of football players.

Hamstring injuries are one of the most common injuries sustained in professional football with 800+ hamstring injuries per year. These hamstring injuries often occur between late swing (eccentric contraction) and early ground contact.PURPOSE: To investigate the correlation of eccentric hamstring strength to muscle volume across positional groups.METHODS:Athletes were divided into three homogeneous groups based on position (big (e.g., linemen), skill (e.g., receivers), combo (e.g., linebackers)). Seventy-three NCAA Division I football players participated (24 big, 37 skill, and 12 combo). Hamstring strength was collected for each leg while performing 3 Nordic curls on a Nordbord device. The peak force of each leg was summed for our data analysis. Collective hamstring volume for each athlete was found through MRI. RESULTS:A Pearson’s product correlation demonstrated an overall moderate correlation (r = 0.52, p < 0.0001) between hamstring muscle volume and strength, with skill players demonstrating a strong correlation (r = 0.66, p < 0.0001), combo players demonstrating a moderate correlation (r = 0.49, p < 0.0001), and big players demonstrating a weak correlation (r = 0.39, p < 0.0001). An ANOVA showed no statistically significant difference of hamstring strength between positional groups (p = 0.1074) relative to hamstring volume (p < 0.0001). CONCLUSION:The observed overall moderate correlation between hamstring strength and muscle volume across positional groups indicates that factors outside of muscle volume contribute to muscle strength. Our data also suggests that, regardless of position, hamstring muscle strength was similar when accounting for volume. Muscle volume was the best predictor of strength for the skill group. However, other factors should be considered, such as motor control factors. In the combo and big groups, these additional factors play a larger role.

BACKGROUND Anosognosia is characterized by a stroke victim’s inability to acknowledge their acquired physical deficits. Such patients could believe they can operate their limbs normally even when they cannot. Patients will often attribute other reasons to explain their deficit (unwillingness to move, a sprain, arthritis, etc).Previous research has reported damage from various brain areas, including several fronto-temporal-parietal areas, insula, and subcortical regions. Many studies suggest that the deficit is caused from impaired sensory feedback coupled with spared motor intentions, which involves premotor, sensory-motor regions, basal ganglia, temporal-parietal junction, insular cortex, and prefrontal cortex. The objective of this study is to confirm the involvement of these brain areas. It is also to identify other possible networks that could contribute to the development of AHP. METHODSWe performed a literature review for case studies of patients presenting with anosognosia for hemiplegia (n=17). The majority of cases were attributed to ischemic stroke (n=15) while the others resulted from hemorrhagic stroke. Lesion network mapping analysis was performed on the 17 lesions with a large cohort of healthy control resting-state scans (n=1000). RESULTSThe main regions to which the lesions were functionally connected included the right transverse temporal gyrus (n=17) and the anterior left insula (n=17). It is also important to note that the lesion networks were found to be negatively correlated with a few areas in the prefrontal cortex. CONCLUSIONFurther research should be done to investigate the involvement of specific areas of the prefrontal cortex in AHP. Some regions in the prefrontal cortex may be negatively correlated; however, past research suggests a positive correlation of other prefrontal regions. It is important that clinicians understand the lesion networks of AHP, as it will guide them to treat patients more effectively. Interventions such as transcranial brain stimulation could become more beneficial to patients, as clinicians will know specific areas of the brain to stimulate to mitigate symptoms of AHP.

Authors: Alex Jarvis, Brooklyn Flowers, June Oaks, Sadie North. Mentors: Tyson Harmon. Insitution: Brigham Young University. Background: Dual tasks have been found to negatively affect language production for people with and without aphasia (Harmon et al., 2023). For people with aphasia (PWA) specifically, previous research suggests that limited working memory or attentional capacity contributes to their difficulty with language tasks (Harmon et al., 2019; Pompon et al., 2015; King & Karen 1996; Obermeyer et al., 2020). One common situation in which communication occurs within a dual task environment is talking while driving. Investigating how talking while driving impacts spoken language could help us better understand how to facilitate both safer driving behaviors and improved communication among friends and family while driving. Longer-term, this understanding can springboard further research addressing assessment and intervention practices in aphasia, which better reflect communication in daily life. Original findings related to speech acoustics revealed that talking while driving led to increased speech intensity and decreased speech time ratios (Glenn, 2017; Simmons, 2016). The potential impact of these driving tasks on spoken language, however, has not been investigated. For the present study, we will conduct a secondary analysis of language samples produced across the aforementioned conditions to understand how they impact spoken language production. Method: Data for the present study was collected for a larger project with initial aims of investigating the impact of driving on speech acoustics (e.g., frequency, intensity). This project also investigated bidirectional interference between speech acoustics and driving as well as the effects of different conversational modalities (e.g., talking on the phone, in person, or through Bluetooth). Forty healthy adults who reported no speech, language, or hearing impairment participated in the study. Participants completed seven tasks, which were presented in a random order: driving without speaking, speaking on a hand-held cell phone, speaking on a hands-free phone, talking to a person next to them speaking on a hand-held cell phone while driving, speaking on a hands-free phone while driving, and talking to a person next to them while driving. Within each of these conditions, participants discussed a topic they selected from a list while completing these tasks. To analyze spoken language, we will first transcribe samples orthographically. These transcriptions will then be coded for lexical-phonological, morphosyntactic, and macro-linguistic errors. Parametric statistical analysis will be used to compare across different age groups. Anticipated Results: We hypothesize that participants will demonstrate increased errors in conditions that involve talking while driving (i.e., dual task conditions) than in conditions that involve talking alone (i.e., single task conditions). Previous research suggests dual-tasking has a negative effect on language including lexical and phonological errors even in non-aphasic participants (Harmon et al., 2023). In this study, we would expect more lexical-phonological (e.g., fillers, revisions, repetitions) and macro-linguistic (e.g., aposiopesis) errors during dual task conditions. For future studies involving PWA’s, we would expect more impaired language in dual-task activities than those without aphasia.

HIV is a retrovirus that has two copies of a single stranded RNA genome. While there is in-depth understanding of the virus and its pathogenesis, no completely effective treatment or vaccine exists. One potential target for therapeutic treatment of HIV is Viral Protein R (Vpr). Vpr is a multi-functional accessory protein encoded by the HIV genome. While HIV is a quickly mutating virus, the vpr gene remains relatively conserved. Mutations in this protein dramatically impact the rate of AIDS progression compared to the wild type (WT) version of Vpr. The Vpr polymorphism R77Q is associated with the Long Term Non Progressor (LTNP) phenotype. Regular AIDS onset is 5-7 years for WT virus and 10 or more years for R77Q. These differences in AIDS progression have been observed in vivo by following people with HIV over time. We have successfully shown that R77Q activates G2 cell cycle arrest more efficiently than WT followed by apoptosis, a death mechanism with less inflammation compared to necrosis. While the molecular mechanism of Vpr-induced apoptosis is known, it is not yet determined why point mutations in Vpr are changing levels of apoptosis. With further experimentation, we have shown that R77Q has decreased expression of pro-inflammatory cytokines compared to WT virus, which may explain why it is associated with the LTNP phenotype. The functions of Vpr come from binding and modifying cellular proteins and enzymes. The focus of our research is to determine what molecular interactions change between Vpr mutants to better understand the shifts in apoptotic levels. Vpr can be found intracellularly in the nucleus, cytoplasm, and mitochondria and extracellularly in secreted proteins and within virions. We will determine Vpr concentration in these various locations for both WT Vpr and the R77Q mutant, starting by measuring extracellular Vpr. To quantify virion-associated Vpr, we have designed a research plan. We will use WT-Vpr plasmids tagged by GFP to create GFP-tagged plasmids with either WT, R77Q or null mutations using site-directed mutagenesis. We will use Sanger sequencing for confirmation of the proper Vpr mutations tagged by GFP. We will then digest the plasmid DNA, leaving only the Vpr-GFP component and use PCR to amplify the sequences. We will transfect null virus plasmid (NL4-3) and Vpr-GFP plasmids into HEK cells to package the null virus and Vpr-GFP plasmids together to create active HIV particles. Using these virus particles, we will infect Hut-78 cells for a short time to allow the virion to enter the cells. We will then measure GFP fluorescence via flow cytometry, allowing us to quantify virion Vpr. This will be run alongside a mock infection as a control. We hypothesize that differences in virion Vpr concentrations exist among Vpr mutants. Through these experiments, we aim to discover more about the role Vpr plays in cell death by apoptosis and contribute to the existing literature exploring the importance of Vpr in HIV-1.

ACSM has again determined that resistance training (RT) and outdoor activities are two of the top ten worldwide fitness trends for 2023. We previously found that RT outdoors had a significantly lower perception of effort (RPE) compared to indoor RT, despite no physiological differences in heart rate (HR) and energy expenditure (EE). However, no study has examined other feelings during RT in indoor or outdoor settings. PURPOSE: To determine how indoor or outdoor environments effect perceptions of fatigue and physical activity enjoyment following RT in recreationally resistance trained adults. METHODS: Twenty-three adult participants (n=10 female, n=13 male) completed this study. The Visual Analog Scale Fatigue (VAS-F) measured perceived fatigue and the Physical Activity Enjoyment Scale – Short Version (PACES-S) measured PA enjoyment, and both were measured at baseline and then immediately following an acute session of indoor or outdoor RT. HR was obtained from a chest strap (Polar H10) and EE from a Portable Metabolic Cart (COSMED K5). Randomly in indoor and outdoor settings, participants completed 4 supersets of the reverse lunge and shoulder press exercises using dumbbells at a light (2 sets) and moderately heavy (2 sets) intensity with 1 superset of 6 repetitions per exercise and 1 min rest between supersets. A paired T-test (for HR & EE comparisons) or one-way repeated measures ANOVA with Sidak post-hoc test (for VAS-F & PACES-S comparisons) were used to determine differences (p<0.05). RESULTS: No significant differences were observed between indoor and outdoor RT for the physiological variables of average HR (129.4±17.2 and 127.75±23.3 bpm, respectively, p=0.66) and EE (30.6±11.5 and 28.3±9.9 kcals, respectively, p=0.06). Perceived fatigue significantly (p<0.0001) increased from baseline (1.13±0.94 arbitrary units, AU’s) following indoor (4.54±1.91 AU’s) and outdoor (3.99±1.54 AU’s) RT, but no environmental differences (p=0.36) were observed. PA enjoyment was not significantly (p range: 0.27-0.93) different between baseline (18.73±1.83 AU’s) and following indoor (18.18±1.99 AU’s) or outdoor (18.36±1.99 AU’s) RT. CONCLUSION: In recreationally resistance trained adults, moderately heavy superset RT in indoor or outdoor settings does not alter perceived fatigue or physical activity enjoyment.

Traditional dental radiography education necessitates the exposure of both clinician and patients to radiation to build clinician skill. Virtual reality (VR) may enable practitioners to learn valuable hands on skills without the use of expensive equipment and without patient or operator exposure to radiation. The purpose of the research is to determine if access to practice in virtual reality (VR) using a specifically designed application, builds skill competency in dental radiology compared with traditional practice methods. A convenience sample of 24 first year dental hygiene students at Utah Tech University were recruited and randomly assigned to the test and control groups. Test group participants were given access to a VR headset with a dental radiology skill practice application installed. Control group participants were given access to traditional dental radiography skill practice methods. To encourage participation, an incentive of a $10 Amazon gift card upon completion of the study was offered. Data will be collected via skill competency evaluation at two-months, mid-term grade scores and final grade scores from the participants’ dental radiology laboratory course. To increase internal validity and reliability, investigators responsible for skill competency evaluation will be blinded and undergo both intra and inter-rater reliability testing to 95% agreement. Upon completion of the Fall semester 2023, data will be analyzed using ANOVA repeated measures between factors accounting for the two independent variables of traditional practice and practice in VR and the dependent variables of competency assessment scores, mid-term and final clinical course grades. Alpha will be set at 0.05. Should it be determined that practice in VR contributes to student learning, VR may enable students to practice additional health science skills in a safe, low stakes environment; thus, increasing student experiential learning and contributing to increased student and patient safety.

Mentors: Marcus Lawrence. Insitution: Southern Utah University. American College of Sports Medicine has again found that wearable technology and resistance training (RT) are two of the top 5 fitness trends in 2023. Our lab recently found that the bicep-worn Polar Verity device was valid and reliable for measuring average and maximal heart rate (HR) during light intensity circuit RT. However, no study has examined other bicep worn devices during RT while also examining heavier intensities. PURPOSE: To determine the concurrent validity of identical Polar OH1 (x2) and Verity Sense (x2) bicep-worn devices in recording average and maximal HR following moderately heavy RT. METHODS: Twenty-one adult participants completed this study (n=10 female, n=11 male; age: 26.1±9.2 yrs; height: 171.3±9.4 cm; mass: 71.4±18.2 kg; RT experience: 5.7±4.9 yrs). The four bicep devices (Polar OH1 x2 and Polar Verity Sense x2) were worn along with the Polar H10 chest strap, criterion for HR. Participants completed 8 supersets of the reverse lunge and shoulder press exercises using dumbbells at a light (4 sets) and moderately heavy (4 sets) intensity with 1 superset of 6 repetitions per exercise (12 repetitions per superset) and 1 min rest between supersets. Data was analyzed for validity (Mean Absolute Percent Error [MAPE] and Lin’s Concordance Coefficient [CCC]), with predetermined thresholds of MAPE<10% and CCC>0.70. Paired t-tests were used to determine differences (p<0.05). RESULTS: For average or maximal HR, neither the Polar Verity Sense 1 (127.2±17.8 or 151.5±16.7bpm) or 2 (125.7±18.8 or 147.9±18.9bpm) or the Polar OH1 1 (128.7±18.5 or 154.5±18.1bpm) or 2 (129.5±18.2 or 156.4±17.4bpm) were significantly (p range: 0.14-0.97) different than the criterion (128.6±19.2 or 149.3±18.0bpm). However, the Polar Verity 1 and 2 were not considered valid for average HR (MAPE range:16.17-17.57%; CCC range: 0.07-0.13) or maximal HR (MAPE range: 11.60-13.33%; CCC range: 0.02-0.29). The Polar OH1 1 and 2 devices were not considered valid, either, for average HR (MAPE range: 17.22-17.25%; CCC range: 0.08-0.09) or maximal HR (MAPE range: 13.24-13.92%; CCC range: .024-0.27). CONCLUSION: Despite our lab previously finding the Polar Verity as valid for HR measurements during light intensity RT, the current bicep-worn devices should not be utilized during heavier intensity RT for accurate HR measurements. Individuals resistance training and utilizing bicep-worn devices for heart rate should use them cautiously.

However, minimal physiological research has been conducted on the two together and none have measured the accuracy of devices measuring repetition counts across exercises. PURPOSE: The purpose of this study was to determine the concurrent validity of four wrist-worn Garmin devices, Instinct (x2), Fenix 6 Pro, and Vivoactive 3, to record repetition counts while performing 4 different exercises during circuit resistance training. METHODS: Twenty participants (n=10 female, n=10 male; age: 23.2  7.7 years) completed this study. Participants completed 4 circuits of 4 exercises (front squat, reverse lunge, push-ups, and shoulder press) using dumbbells at a light intensity with 1 set of 10 repetitions per exercise and 30 seconds rest between exercises and 1-1.5 min rest between circuits. Mean absolute percent error (MAPE, ≤10%) and Lin’s Concordance Coefficient (CCC, ρ≥0.7) were used to validate the device’s repetitions counts in all exercises compared to the criterion reference manual count. Dependent T-tests determined differences (p≤0.05). RESULTS: No devices were considered valid (meeting both the threshold for MAPE and CCC) for measuring repetition counts during front squats (MAPE range: 3.0-18.5% and CCC range: 0.27-0.68, p value range: 0.00-0.94), reverse lunge (MAPE range: 44.5-67.0% and CCC range: 0.19-0.31, p value range: 0.00-0.28), push-ups (MAPE range: 12.5-67.5% and CCC range: 0.10-0.34, p value range: 0.07-0.83), and shoulder press (MAPE range: 18.0-51.0% and CCC range: 0.11-0.43, p value range: 0.00-0.79) exercises. CONCLUSION: The wearable wrist-worn devices were not considered accurate for repetition counts and thus manual counting should be utilized. People who strength train using free weights will need to wait for either improved repetition counting algorithms or increased sensitivity of devices before this measure can be obtained with confidence.

Cytomegalovirus (CMV) is the leading cause of sensorineural hearing loss, the most prevalent form of permanent hearing loss, worldwide. CMV treatment requires long term administration of nucleoside analog antivirals such as ganciclovir (GCV). Although ganciclovir effectively inhibits CMV, it also inhibits neutrophils, an essential component of the immune system, reducing optimal treatment duration. Previous studies have demonstrated that ganciclovir toxicity can be reduced while maintaining effective CMV inhibition by combining subtherapeutic doses of ganciclovir with quercetin, an FDA approved hydrophobic flavonoid with antiviral properties, solubilized with a mitochondria-targeting drug delivery vehicle, Poloxamer 188 (P188). Further efforts have been made to optimize the combinatorial ganciclovir with quercetin encapsulated in P188 (GCV-QP188) treatment by exploring the potential benefits of adding antioxidant vitamins to the GCV-QP188 treatment. One of the pathways by which CMV induces hearing loss is the generation of excess reactive oxygen species, specifically in the mitochondria. Current literature suggests that the toxic effects of the reactive oxygen species produced by CMV in the could be reduced via natural vitamin antioxidant treatments. Ascorbic acid, also known as vitamin C, was the first antioxidant vitamin investigated due to its synergistic antiviral properties when paired with quercetin to treat SARS-CoV-2. Yet, the addition of ascorbic acid into the combinatorial treatment was more toxic than the existing GCV-QP188 treatment. Current efforts are concentrated on assessing the effect of selectively delivering hydrophobic antioxidants to the mitochondria of CMV infected mouse fibroblast cells as targeted antioxidant delivery will require lower antioxidant concentrations, reducing associated toxicity. The addition of hydrophobic antioxidants retinol and alpha-tocopherol, vitamins A and E respectively, delivered via mitochondria-targeting P188 to the existing GCV-QP188 treatment is being investigated to determine if it will significantly improve GCV-QP188 treatment efficacy.

AbstractBackgroundWomen living with HIV (WLHIV) commonly experience internalized HIV stigma, which refers to how they feel about themselves as a person living with HIV. Internalized stigma interferes with HIV care seeking behavior and may be particularly heightened during the pregnancy and postpartum periods. This thesis aimed to describe internalized HIV stigma among WLHIV giving birth, identify factors associated with internalized HIV stigma, and examine qualitatively the impacts of internalized HIV stigma on the childbirth experience.MethodsPostpartum WLHIV (n=103) were enrolled in the study between March and July 2022 at six clinics in the Kilimanjaro Region, Tanzania. Participants completed a survey within 48 hours after birth, prior to being discharged. The survey included a 13-item measure of HIV-related shame, which assessed levels of internalized HIV stigma (Range: 0-52). Univariable and multivariable regression models examined factors associated with internalized HIV stigma. Qualitative in-depth interviews were conducted with pregnant WLHIV (n=12) and postpartum WLHIV (n=12). Thematic analysis, including memo writing, coding, and synthesis, was employed to analyze the qualitative data.ResultsThe survey sample had a mean age of 29.1 (SD = 5.7), and 52% were diagnosed with HIV during the current pregnancy. Nearly all participants (98%) endorsed at least one item reflecting internalized HIV stigma, with an average endorsement of 9 items (IQR = 6). The most commonly endorsed items were: “I hide my HIV status from others” (87%), “When others find out I have HIV, I expect them to reject me” (78%), and “When I tell others I have HIV, I expect them to think less of me” (75%). In the univariable model, internalized stigma was associated with two demographic characteristics: being Muslim vs. Christian (ß = 7.123; 95%CI: 1.435, 12.811), and being in the poorest/middle national wealth quintiles (ß = 5.266; 95%CI: -0.437, 10.969). Internalized stigma was associated with two birth characteristics: having first birth vs. having had previous births (ß = 4.742; 95%CI: -0.609, 10.093), and attending less than four antenatal care appointments (ß = 5.113; 95%CI: -0.573, 10.798). Internalized stigma was associated with two HIV experiences: being diagnosed with HIV during the current pregnancy vs. diagnosis in a prior pregnancy (ß = 5.969; 95%CI: -1.196, 10.742), and reporting experiences of HIV stigma in the health system (ß = 0.582; 95%CI: 0.134, 1.030). In the final multivariable model, internalized stigma was significantly associated with being Muslim vs. Christian (ß = 6.80; 95%CI: 1.51, 12.09), attending less than four antenatal care appointments (ß = 5.30; 95%CI: 0.04, 10.55), and reporting experiences of HIV stigma in the health system (ß = 0.69; 95%CI: 0.27, 1.12). Qualitative discussions revealed three key themes regarding the impact of internalized HIV stigma on the childbirth experience: reluctance to disclose HIV status, suboptimal adherence to care, and the influence on social support networks.ConclusionWLHIV giving birth in this sample experience high rates of internalized HIV stigma. This stigma was significantly associated with being Muslim, as opposed to being Christian, attending less than four ANC appointments, and reporting experiences of HIV stigma in the healthcare setting. Other factors that were correlated to higher levels of internalized stigma were socioeconomic status, parity, and timing of HIV diagnosis, all of which can impact access to and engagement in healthcare services during the intrapartum and postpartum periods. Internalized HIV stigma impacts the childbirth experience for WLHIV, making the labor and delivery setting an important site for intervention and support.

Authors: ANNA EDLER, RYAN KUNKLER, CASEY WEBB, JACOB MANNING, MARCUS M LAWRENCE. Mentors: Marcus Lawrence. Insitution: Southern Utah University. Climbing (sport and bouldering) has become a very popular hobby for people all over the globe.Now that climbing is an Olympic sport the need for understanding best training practices through evidence, not anecdotal experience, has grown. Using the International Rock Climbing Research Association (IRCRA) individual grading scale based on route completion difficulty,some research has shown that upper limb strength is important for individuals to progress from recreational/intermediate to more advanced/elite levels. However, many studies use non-sportspecific measurements (i.e., hand dynamometer versus a finger climbing hold) and none have assessed rate of force development (RFD) or lower body strength contributions. PURPOSE: To test the hypothesis that compared to recreational/intermediate climbers advanced climbers would have greater dominant and non-dominant upper-body strength and finger RFD as well as lower body compound strength. METHODS: Nineteen subjects (n=8 female and n=11 male;age: 24.7±7.5 yrs; height: 177.6±7.8 cm; mass: 76.0±14.9 kg; IRCRA Sport Grade: 14.1±6.7; n=10 intermediate, n=9 advanced) completed this study. During a single session, following a standardized 3-5 min. warm-up all participants dominant and non-dominant finger strength andRFD (using a Tindeq dynamometer load cell attached via static rope to a 20mm edge) as well as shoulder strength (using the same Tindeq load cell with a static rope attached to an olympic ring), and lower-body compound strength (isometric mid-thigh pull using G-strengthdynamometer load cell attached to a straight bar with a static rope) were assessed. Three trials were done on each measurement with 1 min. between trials and 3-5 min. between tests. Unpaired t-tests determined differences, p<0.05. RESULTS: Across every measurementadvanced climbers had significantly (p<0.05) higher values for absolute and relative (normalized to body weight, BW) measurements. As absolute and non-dominant results were similar we onlyreport dominant relative results, where appropriate. Indeed, compared to intermediate climbers advanced climbers had significantly higher relative dominant finger RFD (9.9±3.7 vs 20.8±9.4N/s*BW -1 ), finger strength (0.5±0.1 vs 0.7±0.3 kg/BW), shoulder strength (0.7±0.2 vs 0.9±0.2 kg/BW), as well as relative compound strength (1.8±0.4 vs 2.6±0.7 kg/BW, respectively). CONCLUSION: Advanced climbers have larger absolute and relative RFD in their fingers,stronger dominant and non-dominant fingers and shoulders, as well as stronger lower body compound strength. Thus, individuals looking to progress from recreational/intermediate climbing grades to advanced/elite should focus on improving total body absolute and relative strength as well as finger RFD.

Opioid Use Disorders Treatment Related Disparities in Patients with Psychiatric IllnessAuthors: Caroline Nielson, Connor Baird, Robert Kagabo, PhD, MSW, MPHAbstractBackgroundThis study is a review of peer-reviewed articles of Opioid Use Disorders (OUD) treatment among individuals with psychiatric illness. OUD is a subset of substance use disorders (SUD) that is chronic and a growing public health concern. There were 47,000 opioid-related deaths in 2018 in the US; OUD is responsible globally for 68% of the drug-related deaths. OUD can result from either prescribed or non-prescribed opioid use. Some populations such as individuals with psychiatric illness have high rates of prescription opioids yet face opioid use treatment and research-related disparities. This review study examines OUD treatment and research-related disparities among patients with psychiatric illness with the goal to improve treatment among this vulnerable population.MethodsUsing PubMed and PsycINFO databases, we performed a search of journal articles regarding OUD treatment which were published between 2010 and 2023. We then completed a review of the journal articles using narrative overview guidelines. All articles reviewed were from randomized controlled trial (RCT) studies. Examples of search terms used include OUD treatment and mental health; OUD and psychiatric illness RCT studies; and opioid use treatment and mental health. Studies included were those of OUD treatment among individuals with psychiatric illness and or with a DSM5 or DSM4 diagnosis. Any studies that did not include OUD treatment and, or a DSM diagnosis, or RCT design were excluded. To avoid duplication, only one journal article from a study was included. ResultsThere were 18 journal articles reviewed that met the inclusion criteria. Treatment periods ranged from 8-24 weeks. Generally, studies excluded individuals with diagnoses such as schizophrenia, schizoaffective disorders, or other serious mental health diagnoses. Several studies included participants with a DSM5 or DSM4 diagnosis of OUD, while excluding individuals with other psychiatric or substance use disorders. Most of the studies used pharmacological treatments and only a few studies had combined pharmacological and behavioral treatments. The common medicines in pharmacological treatments were methadone, buprenorphine, and naltrexone.ConclusionOUD treatment and research related disparities exist among individuals with psychiatric illness, yet this is the population who suffer most from OUD. Additional studies regarding OUD treatment among individuals with psychiatric illness are needed to improve OUD treatments and reduce OUD-related morbidity and mortality rates.

Authors: Hannah Smith. Mentors: Jeff Parker. Insitution: Brigham Young University. The Arabic language uses a rich system of patterns called verb forms to create verbs with related meanings from roots made of consonants. For example, the root k-t-b, in form I, kataba, means ‘to write.’ When it appears in form II as kattaba, it means ‘to make someone write.’ In form III, kaataba, it means ‘to exchange letters,’ ‘to correspond’ (Wehr, 2019). There are ten commonly used verb forms, although not every root is used in every form. As Arabic has been exposed to English and speakers borrow verbs from English into their Arabic, they make choices about how and whether to integrate these foreign words into the verb forms. For example, the verb ‘to block (on social media),’ with the derived root b-l-k, is used in form II, ballaka, ‘to block.’ Other borrowed verbs, however, don’t get integrated in this way. Instead, they are used as a noun with a native Arabic verb, usually ‘amila, ‘to do.’ For example, English ‘to delete’ becomes ‘amila daliit, literally ‘to do a delete.’ This study aims to understand what factors influence when and how completely borrowings from English like these are integrated into the verb forms in Jordanian Arabic (JA) by interviewing university students in Amman, Jordan. The interviews are primarily focused on four forms in which borrowings in JA frequently appear (Salem, 2015). Initial data from a group of eight participants shows a general acceptance for the borrowings in their base forms, with much more variation in speakers’ intuitions regarding their usage in other forms. For example, all eight participants perceive ‘to block,’ ballaka, as a completely acceptable word used by most people. However, only two participants felt the same way about its counterpart form, taballaka, ‘to be blocked,’ whereas two other participants perceived it as something no one would ever use. Furthermore, some participants perceive verbs that rely on ‘to do,’ such as ‘to delete,’ to be in the beginning stages of integration, with three of eight interviewees stating that some of these verbs actually are acceptable in verb form II. Thus far, the perceptions of all the borrowings seem to indicate that speakers believe that integration of borrowed verbs is a gradual process. Furthermore, in addition to other factors, the extent to which the verbs are integrated in JA seems to be affected in large part by cultural perceptions of how foreign the verbs are, a factor that has not been noted in previous studies on the subject.

How reliable is emotional facial expression coding within and across raters? Background Emotion, described as “physiological forces, located within individuals, that bolster our sense of uniqueness....” (Katriel, 2015, p. 57) is a critical aspect of day-to-day communication. For people with acquired language disorders post-stroke (i.e., aphasia), this interaction is particularly important due to relatively spared emotional processing, which has the potential to either facilitate or interfere with language processing (see e.g., Harmon et al., 2022; Ramsberger, 1996). The present study is part of a larger project, which seeks to determine whether people with aphasia exhibit more emotional facial expressions during personal narrative discourse than adults who do not have aphasia and whether these expressions are more emotionally arousing. The present study specifically seeks to investigate the reliability of facial coding by comparing average frequency and intensity of emotional facial expressions both within and across undergraduate student coders. Methods In order to quantify emotional facial expression frequency and intensity, undergraduate research assistants are trained to code facial expressions using a modified FACES protocol (Kring and Sloan, 2007). The modified protocol will be used to code emotional facial expressions of video footage that was obtained from participants while they told personal narratives (e.g., talking about an illness they experienced or an important life event). First, research assistants identify the baseline facial expression for each participant. Next, research assistants code transitions from a neutral expression to an emotional facial expression for valence (positive/negative) and intensity. Intensity ratings are scaled from 1 to 4 depending on how many units of the face are involved within the corresponding facial expression. Using this protocol, research assistants will begin facial coding after they are trained and demonstrate mastery by attaining 80% agreement with a master code. Upon completing initial data coding, research assistants will be assigned to recode 10% of previously completed video samples as well as 10% of samples that were previously coded by other coders. This secondary coding will be used to measure intra- and inter-rater reliability across dependent variables: frequency of emotional facial expressions, intensity of positive facial expressions, and intensity of negative facial expressions. Average frequency of emotional facial expressions will be calculated as the number of facial expressions produced per minute within a given sample. Intensity of positive and negative facial expressions will be calculated as the mean intensity within each valence respectively. The average frequency and intensity of initial and reliability codes will then be compared using Pearson’s correlation coefficient. Anticipated Results We anticipate that intra- and inter-rater reliability will be above 0.8. Through a strict training process, research assistants will calibrate their coding to achieve 80% agreement with the master code. We anticipate this training process to produce effective intra- and inter-rater reliability. Findings will be important for determining the reliability of facial coding procedures and trustworthiness of data for answering questions related to the longer-term project.

Authors: Lizzie Stewart, Hayden Underwood, Dallas Goolsby, Spencer Sears. Mentors: Camilla Hodge. Insitution: Brigham Young University. Social connection is critical to understanding how individuals interact with one another and form social bonds in groups. Our research evaluates the effects on social connection based on the Ecology of Family Experiences framework, which considers the interplay between three domains: family, activity, and time. We believe that the EFE is a transferable framework that will have important social implications for understanding interpersonal relationships and designing experiences intended to increase social connection. In this study, we examine the relationship between social connection and two variables: 1) social interaction, or the behavior between two or more people crossing paths. Social interaction considers joint or parallel interaction styles between people; 2) self-disclosure, or interaction where one intends to willfully and deliberately divulge something personal to another. We hypothesize that social interaction and self-disclosure influence social connections outside the family context. We seek to shed light on the mechanisms that shape and alter the quality and depth of interpersonal connection. In our experiment, we used a 2x2 quasi-experimental design. Participants were assigned to one of four conditions varying in self-disclosure (high vs. low) and social interaction (joint vs. parallel). Self-disclosure questions asked participants to answer prescribed questions, including highly personalized questions (high disclosure) and non-personalized information (low disclosure). Participants either interacted with a partner (joint) or wrote responses next to a partner without verbal communication (parallel). Social connection was measured using the Inclusion of Others and Self Scale. The sample consisted of 148 university students. The average participant was a white, unmarried, 20-year-old from a middle- to high-class economic background. Data analysis was conducted using mixed model techniques that took into account the unique dyadic relationship of each pairing. Results suggested a significant interaction between self-disclosure and social interaction (t = 2.354, p < 0.05). With high self-disclosure and joint activity having a mean of 4.54, high self-disclosure and parallel activity having a mean of 2.33, low self-disclosure and joint activity having a mean of 3.47, and low disclosure parallel activity having a mean of 2.01. These findings highlight the importance of self-disclosure and social interaction styles in influencing social connection, extending the applicability of the EFE framework beyond the family unit.

Implicit bias occurs automatically and unintentionally based on a person’s lifetime experience and cultural history (National Institutes of Health, 2022; Handelsman & Sakraney, 2015). In this study, implicit bias is evaluated through the lens of a transformative diversity, equity, inclusion, and belonging business course. DEIB originated in the 1960s in response to equal employment and affirmative action laws (Sarrett, 2022). Studies show that Millennials and Gen Z generations are the most diverse populations ever in the United States (Stamps & Foley, 2023). Benefits of DEIB include the creation of a more unified, diverse, and successful workplace, less biases in hiring, team development, promotions, and who companies do business with (El-Amin, 2022). This study’s theoretical framework is based on the transformative learning theory which seeks to understand and promote human development through learning. Transformation is more than "knowing more" through time; when a learner is transformed by education they undergo a shift in perspective, and after that shift, they cannot go back to see the world the way they once did, at least in some small way (Wichita State University). The class was designed with experiential learning approaches and introduces a variety of DEIB concepts such as privilege, unconscious bias, assumptions, and intersectionality. Students interacted with a variety of experiential components such as DEIB events, panels, and interviews which addressed various minority groups. At the beginning of the DEIB course, students completed an IAT test focused on racial bias. The IAT test is known as the Implicit Association Test that uses positive and negative connotative words in association with pictures of minority groups to measure automatic reactions targeting an individual's level of implicit bias towards one minority group versus another. After students completed the racial IAT test, scores were recorded representing the level of implicit racial bias students held towards white people vs. black people. At the conclusion of the 14-week-long course, students completed the same IAT test on racial bias. Scores were recorded once again, comparative with previous IAT scores, to evaluate whether the amount of racial implicit bias had changed as a result of participating in the DEIB course and its curriculum. Data was then analyzed visually comparing the means from the pre to post test results. The data was analyzed using this method because the sample size was not large enough to return what the researchers considered to be reliable results. More data is available for this study, but has not been cleaned and matched, this process is currently taking place. Once the data is available, the researchers will use paired sample T-tests to conduct a full analysis. Additionally, descriptive analysis will be represented in the form of histograms of pre and post test scores observing the progression towards less implicit bias. The mean for the pre-test was .78 (sdv=1.34, n=171) and the post-test was .63 (std=1.38, n=144). Our sample size was 181 participants with 25 that chose not to answer. Demographics of participants consisted of 66% Caucasian, 3% Hispanic, 2% Asian, 2% Native Hawaiian, 1% other, and 26% who chose not to respond. The average age of participants was 21. Gender of participants consisted of 121 females and 34 males. Visual examinations of the means suggest there was migration toward 0, which would represent little to no bias and the class was making a difference in participants’ implicit bias scores. This study underscores the utility of DEIB instruction in promoting changes in bias. The impact of changes in implicit bias through this learning coupled with DEIB principles in a transformative way will greatly influence the workforce for generations to come.

Lower Limb Asymmetries in Unilateral Jump Mechanics as Possible Risk Factor for Injury in Collegiate WrestlersJacob Armstrong and Tyler Standifird 1Utah Valley University, Orem, Ut. Injuries impose a multi-faceted burden on athletes, coaches, and sporting organizations, encompassing physical, financial, and psychological ramifications. Determining risk factors and identifying them in athletes has been a widespread goal amongst researchers and practitioners in attempts to reduce injuries. Investigating Limb asymmetries, or limb imbalances, has been a common approach in identifying such factors but has shown inconsistent correlations with injuries (Melony, 2018). Moreover, much of the current research investigates asymmetries of outward limb performance (i.e., Strength, flexibility, jump performance etc.) and not asymmetries of internal joint mechanics. Identifying relationships between internal joint asymmetries and lower limb injuries can further aid coaches, practitioners and sporting organizations in effectively identifying injury risks. Purpose: The purpose of this study was to investigate internal joint asymmetries of the lower limbs during unilateral jump testing and their association with injuries in collegiate wrestlers. Methods: 23 healthy Division 1 NCAA collegiate wrestlers performed single leg depth jumps from a 12-inch platform unto force plates (Bertec Inc 1000 hz). Additionally, markerless motion capture technology was used to collect video data using Qualisys Mocap cameras (Qualisys North America, Inc. Buffalo Grove, Ill). Imagery was then processed in Theia (Theia Markerless, Inc. Kingston, Ontario) to produce 3d joint locations for all the joints of the lower extremity. Each wrestler performed 3 jumps with the left leg and then 3 with the right leg for a total of 6 jump attempts. 7 total variables were calculated and recorded in Visual 3D software (Dolomite Enterprises, LLC. Tallahassee, FL) for each wrestler and leg: drop max vertical force, vertical loading rate on drop, peak knee adduction angle, peak knee abduction moment, peak knee adduction moment, peak knee flexion angle, peak knee extension moment. Averages, standard deviations and percent differences were also calculated and compared between limbs. Injury history data was also collected from each participant from the year 2021 - present day.Results: Averaging found asymmetries in peak knee adduction angle with the left knee being greater than the right by 4.9 degrees (p=0.001), peak knee abduction moment with the right knee being greater than the left by .95 newton meters (p=0.001), and peak knee adduction moment with the left knee being greater than the right by .44 newton meters (p=0.001). All significant asymmetries were found in the frontal plane. No significant asymmetries were found in the sagittal plane. Injury history report found a total of 24 seperate lower limb injuries within the described timeframe. 16 associated with the right limb and 8 associated with the left. A total of 5 ACL injuries, 8 MCL injuries, 5 LCL Injuries, 3 meniscus injuries, and 3 ankle injuries. Conclusion: Asymmetry trends in collegiate wrestlers potentially indicate that internal joint asymmetry is specific to sport or activity. Also, internal joint asymmetry could be a potential indicator for training protocols for overall better movement and health within the studied population. Asymmetrical values of the peak knee adduction angle, peak knee abduction moment, and peak knee adduction moment combined with the frequency of knee injuries of the participants indicate possible positive correlations between the magnitude of asymmetry discovered and injury risk.
