    A Two-Stage Approach Integrating Provisional Biomaterial-Mediated Stabilization Followed by a Definitive Treatment for Managing Volumetric Muscle Loss Injuries
    (MDPI, 2024-06-06) Clark, Andrew R.; Kulwatno, Jonathan; Kanovka, Sergey S.; Klarmann, George J.; Hernandez, Claudia E.; Natoli, Roman M.; McKinley, Todd O.; Potter, Benjamin K.; Dearth, Christopher L.; Goldman, Stephen M.; Orthopaedic Surgery, School of Medicine
    Treatment of volumetric muscle loss (VML) faces challenges due to its unique pathobiology and lower priority in severe musculoskeletal injury management. Consequently, a need exists for multi-stage VML treatment strategies to accommodate delayed interventions owing to comorbidity management or prolonged casualty care in combat settings. To this end, polyvinyl alcohol (PVA) was used at concentrations of 5%, 7.5%, and 10% to generate provisional muscle void fillers (MVFs) of varying stiffness values (1.125 kPa, 3.700 kPa, and 7.699 kPa) to stabilize VML injuries as part of a two-stage approach. These were implanted into a rat model for a duration of 4 weeks, then explanted and either left untreated (control) or treated through minced muscle grafting (MMG). Additional benchmarks included acute MMG and unrepaired groups. At the MVF explant, the 7.5% PVA group exhibited superior neuromuscular function compared to the 5% and 10% PVA groups, the least fibrosis, and the largest median myofiber size among all groups at the 12-week endpoint. Despite the 7.5% PVA’s superiority amongst the two-stage treatment groups, neuromuscular function was neither improved nor impaired relative to acute treatment benchmarks. This suggests that the future success of a two-stage VML treatment strategy will necessitate a more effective definitive intervention.

    Acceptability of an mHealth App for Youth With Substance Use and Mental Health Needs: Iterative, Mixed Methods Design
    (JMIR Publications, 2021-12-24) Adams, Zachary; Grant, Miyah; Hupp, Samantha; Scott, Taylor; Feagans, Amanda; Phillips, Meredith Lois; Bixler, Kristina; Nallam, Phani Teja; La Putt, Dorothy; Psychiatry, School of Medicine
    Background: Treating substance use disorders (SUDs) during adolescence can prevent adult addiction and improve youth outcomes. However, it can be challenging to keep adolescents with SUDs engaged in ongoing services, thus limiting potential benefits. Developmentally appropriate tools are needed to improve treatment engagement during and between sessions for youth with SUDs and mental health disorders. Mobile health apps may augment or replace psychotherapy components; however, few have been developed specifically for youth with SUDs following user-guided design principles, which may limit their appropriateness and utility. Formative research on acceptability to intended end users is needed before the efficacy of such tools can be examined. Objective: This study involves user-centered, iterative development and initial user testing of a web-based app for adolescents with SUDs and mental health concerns. Methods: Adolescents aged 14 to 17 years with past-year involvement in outpatient psychotherapy and behavioral health clinicians with adolescent SUD treatment caseloads were recruited. Across 2 assessment phases, 40 participants (alpha: 10 youths and 10 clinicians; beta: 10 youths and 10 clinicians) viewed an app demonstration and completed semistructured interviews and questionnaires about app content and functionality. Results: Participants expressed positive impressions of the app and its potential utility in augmenting outpatient therapy for youth with SUDs and mental health concerns. Noted strengths included valuable educational content, useful embedded resources, and a variety of activities. Adolescents and clinicians favored the app over conventional (paper-and-pencil) modalities, citing convenience and familiarity. The app was found to be user-friendly and likely to improve treatment engagement. Adolescents suggested the inclusion of privacy settings, and clinicians recommended more detailed instructions and simplified language. Conclusions: The novel app developed here appears to be a promising, acceptable, and highly scalable resource to support adolescents with SUDs and mental health concerns. Future studies should test the efficacy of such apps in enhancing adolescent behavioral health treatment engagement and outcomes.

    Arsenal
    (2018) Carroll, Brenna; Jefferson, Corey; Baker, Lesley; Robertson, Jean
    Traumatic experience inspires the human drive for expression. Survivors carry the memory of trauma with them throughout their lives while they struggle to comprehend its impact. They maintain a fragile stability as their capacity to more forward is challenged and their perception of the world around them is altered. The force of memory compels those who have survived a traumatic event to build a defensive arsenal and to search for and to convey an understanding of their experience. My minimalist abstract ceramic sculpture examines the incidence of trauma and explores the transference of concepts and emotions associated with its effects.

    Associations among Impulsivity, Trauma History, and Alcohol Misuse within a Young Adult Sample
    (Elsevier, 2017) Bountress, Kaitlin E.; Adams, Zachary W.; Gilmore, Amanda K.; Amstadter, Ananda B.; Thomas, Suzanne; Danielson, Carla Kmett; Psychiatry, School of Medicine
    Objective: Young adult alcohol misuse is associated with numerous long-term adverse outcomes. Given the link between impulsivity and alcohol use, we examined whether three impulsivity-related traits differentially predicted number of drinks per drinking day (DDD). We also examined whether these effects varied for those with different trauma histories. Method: The current study (n=254) examined motor, non-planning, and attentional impulsivity as predictors of DDD. It also examined whether impulsivity was differentially predictive of DDD across individuals in: a control group (non-trauma exposed), a trauma exposed but non-PTSD group, and a PTSD group. Results: Regardless of group, more motor impulsivity was associated with more DDD. The effect of non-planning impulsivity varied according to trauma history. Specifically, more non-planning impulsivity predicted more DDD for those without PTSD. Finally, attentional impulsivity was not predictive of DDD. Conclusions: Young adults with high levels of motor impulsivity, regardless of trauma history, may be a particularly high-risk group in terms of propensity for alcohol use/misuse. Additionally, high levels of non-planning impulsivity may signify those at greater risk for alcohol misuse, among those without PTSD. Motor impulsivity and non-planning impulsivity may serve as useful intervention targets in alcohol misuse prevention efforts. Implications for future research in this area are discussed.

    Associations of subjective and objective stress responses with interpersonal trauma, PTSD, stress-induced drinking, and drinking to cope in young adults
    (American Psychological Association, 2021) Danielson, Carla Kmett; Hahn, Austin M.; Bountress, Kaitlin E.; Adams, Zachary W.; Calhoun, Casey; Amstadter, Ananda B.; Thomas, Suzanne; Psychiatry, School of Medicine
    Objective: To understand how interpersonal trauma (IPT), stress response, and drinking to cope converge to predict stress-induced drinking, a risk factor for alcohol use disorder. Method: Young adults with no substance use disorder were classified into three trauma history groups: (a) IPT with PTSD (n = 27), (b) IPT without PTSD (n = 35), and (c) Control (no trauma-history/no PTSD; n = 36). Participants completed a baseline assessment, including a structured clinical interview, to confirm PTSD diagnosis, followed by the Trier Social Stressor Task (TSST) and an alcohol use task. Subjective units of distress and blood serum cortisol were collected at standardized timepoints throughout the tasks. Results: In all three groups (PTSD, IPT, control), males consumed more alcohol in the lab than females. Participants in the PTSD group had significantly higher drinking to cope motives, which were associated with greater subjective reactivity; however, neither drinking to cope motives nor subjective reactivity to the TSST predicted post-stressor alcohol consumption for those with PTSD. Conclusions: The interplay among trauma history, stress, and drinking among young adults is nuanced; additional lab-based studies are needed to further clarify the nuanced connection between trauma history, acute stress reactions, and alcohol use.

    Adverse posttraumatic neuropsychiatric sequelae (APNS) are common among civilian trauma survivors and military veterans. These APNS, as traditionally classified, include posttraumatic stress, postconcussion syndrome, depression, and regional or widespread pain. Traditional classifications have come to hamper scientific progress because they artificially fragment APNS into siloed, syndromic diagnoses unmoored to discrete components of brain functioning and studied in isolation. These limitations in classification and ontology slow the discovery of pathophysiologic mechanisms, biobehavioral markers, risk prediction tools, and preventive/treatment interventions. Progress in overcoming these limitations has been challenging because such progress would require studies that both evaluate a broad spectrum of posttraumatic sequelae (to overcome fragmentation) and also perform in-depth biobehavioral evaluation (to index sequelae to domains of brain function). This article summarizes the methods of the Advancing Understanding of RecOvery afteR traumA (AURORA) Study. AURORA conducts a large-scale (n = 5000 target sample) in-depth assessment of APNS development using a state-of-the-art battery of self-report, neurocognitive, physiologic, digital phenotyping, psychophysical, neuroimaging, and genomic assessments, beginning in the early aftermath of trauma and continuing for 1 year. The goals of AURORA are to achieve improved phenotypes, prediction tools, and understanding of molecular mechanisms to inform the future development and testing of preventive and treatment interventions.

    Basic symptoms of schizophrenia are related to symptoms of traumatic stress: A pivotal role of sensitization. An observational study
    (Wolters Kluwer, 2022-07-15) Pec, Ondrej; Lysaker, Paul H.; Bob, Petr; Psychiatry, School of Medicine
    Introduction: Subjective cognitive deficits have been broadly reported in schizophrenia and described by Huber as basic symptoms. It remains unclear however to what extent they may be related to psychosocial stressors including trauma. Methods: We assessed basic symptoms using the Frankfurt Complaint Questionnaire (FCQ) in a sample of 40 patients with schizophrenia. Trauma-related symptoms were assessed concurrently using the Trauma Symptom Checklist-40, symptoms of dissociation using the Dissociative Experiences Scale, and sensitization phenomena using the Complex Partial Seizure-like Symptoms Inventory and Limbic System Checklist-33. Psychotic symptoms were measured by Health of the Nation Outcome Scales. The dosage of antipsychotic medication was assessed in terms of equivalents of chlorpromazine, and antidepressant medication in terms of equivalents of fluoxetine. Spearman correlations were performed to explore the relationship between FCQ and other trauma-related measures. To determine the relative contributions of trauma-related symptoms to basic symptoms a linear regression analysis was performed. Results: The results showed that higher levels of basic symptoms of schizophrenia were associated with greater levels of symptoms of dissociation, traumatic stress, and sensitization or kindling-like processes in schizophrenia. Among the trauma-related variables, sensitization phenomena assessed with Complex Partial Seizure-like Symptoms Inventory were closely associated with basic symptoms. Discussion: These results indicate that basic symptoms measured by FCQ might be related to trauma. The potential of trauma to influence neurodevelopmental hypotheses of schizophrenia is discussed.

    Bilateral trauma case conferences: an approach to global surgery equity through a virtual education exchange
    (Springer Nature, 2023) Bhatia, Manisha B.; Munda, Beryl; Okoth, Philip; Carpenter, Kyle L.; Jenkins, Peter; Keung, Connie H.; Hunter‑Squires, JoAnna L.; Saruni, Seno I.; Simons, Clark J.; Surgery, School of Medicine
    Purpose: With increased interest in international surgical experiences, many residency programs have integrated global surgery into their training curricula. For surgical trainees in low- and middle-income countries (LMICs), physical exchange can be costly, and laws in high-income countries (HICs) prevent LMIC trainees from practicing surgery while on visiting rotations. To enrich the educational experience of trainees in both settings, we established a monthly virtual trauma conference between surgery training programs. Methods: General surgery teams from two public institutions, a public university with two surgical training programs in Kenya and a public university with two level I trauma centers in the United States, meet monthly to discuss complex and interesting trauma patients. A trainee from each institution presents a clinical case vignette and supplements the case with pertinent peer-reviewed literature. The attendees then answer a series of multiple-choice questions like those found on surgery board exams. Results: Monthly case conferences began in September 2017 with an average of 24 trainees and consultant surgeons. Case discussions serve to stimulate dialogue on patient presentation and management, highlighting cost-conscious, high-quality care and the need to adapt practice patterns to meet resource constraints and provide culturally appropriate care. Conclusion: Our 5-year experience with this virtual case conference has created a unique and robust surgical education experience for trainees and surgeons who have withstood the effects of the pandemic. These case conferences have not only strengthened the camaraderie between our departments, but also promoted equity in global surgery education and prioritized the learning of trainees from both settings.

    Childhood adversities and risk of posttraumatic stress disorder and major depression following a motor vehicle collision in adulthood
    (Cambridge University Press, 2023-01-10) Ziobrowski, H. N.; Holt-Gosselin, B.; Petukhova, M. V.; King, A. J.; Lee, S.; House, S. L.; Beaudoin, F. L.; An, X.; Stevens, J. S.; Zeng, D.; Neylan, T.

D.; Bruce, S. E.; Miller, M. W.; Pietrzak, R. H.; Joormann, J.; Barch, D. M.; Pizzagalli, D. A.; Harte, S. E.; Elliott, J. M.; Ressler, K. J.; McLean, S. A.; Koenen, K. C.; Kessler, R. C.; Emergency Medicine, School of Medicine
    Aims: Childhood adversities (CAs) predict heightened risks of posttraumatic stress disorder (PTSD) and major depressive episode (MDE) among people exposed to adult traumatic events. Identifying which CAs put individuals at greatest risk for these adverse posttraumatic neuropsychiatric sequelae (APNS) is important for targeting prevention interventions. Methods: Data came from n = 999 patients ages 18-75 presenting to 29 U.S. emergency departments after a motor vehicle collision (MVC) and followed for 3 months, the amount of time traditionally used to define chronic PTSD, in the Advancing Understanding of Recovery After Trauma (AURORA) study. Six CA types were self-reported at baseline: physical abuse, sexual abuse, emotional abuse, physical neglect, emotional neglect and bullying. Both dichotomous measures of ever experiencing each CA type and numeric measures of exposure frequency were included in the analysis. Risk ratios (RRs) of these CA measures as well as complex interactions among these measures were examined as predictors of APNS 3 months post-MVC. APNS was defined as meeting self-reported criteria for either PTSD based on the PTSD Checklist for DSM-5 and/or MDE based on the PROMIS Depression Short-Form 8b. We controlled for pre-MVC lifetime histories of PTSD and MDE. We also examined mediating effects through peritraumatic symptoms assessed in the emergency department and PTSD and MDE assessed in 2-week and 8-week follow-up surveys. Analyses were carried out with robust Poisson regression models. Results: Most participants (90.9%) reported at least rarely having experienced some CA. Ever experiencing each CA other than emotional neglect was univariably associated with 3-month APNS (RRs = 1.31-1.60). Each CA frequency was also univariably associated with 3-month APNS (RRs = 1.65-2.45). In multivariable models, joint associations of CAs with 3-month APNS were additive, with frequency of emotional abuse (RR = 2.03; 95% CI = 1.43-2.87) and bullying (RR = 1.44; 95% CI = 0.99-2.10) being the strongest predictors. Control variable analyses found that these associations were largely explained by pre-MVC histories of PTSD and MDE. Conclusions: Although individuals who experience frequent emotional abuse and bullying in childhood have a heightened risk of experiencing APNS after an adult MVC, these associations are largely mediated by prior histories of PTSD and MDE.

    Childhood Unraveled
    (2023) Edgerly, Brianna; Setser, Meredith; Petranek, Stefan; Potter, William; Baldner, Karen
    Through the exploration of handmade paper with nostalgic imagery I have been transforming the fragments and sorrow of my memories into a cathartic experience shared between the artist and the viewer. I use Van Dyke brown printing to translate photographic imagery that reminds me of my childhood and create my version in the form of an abstracted illustration. This translation from photography to drawing allows for a personal reprocessing of the original memory. I print the illustrations onto handmade cotton paper that together create an aesthetically intriguing collection of objects. They are a physical record of how the artistic process has also been a healing one when it comes to my mental health. It also offers the spectator a moment to slow down and reflect on how they process their memories by witnessing how I have processed my own. As a result, my work creates a stronger empathetic understanding of how someone’s past can affect them in the present moment. The delicately intricate use of the material creates a curiosity in the spectator to further interact with the work. As they move in closer to inspect the work, tears, stains, and other imperfections litter both prints and cast forms alike. By allowing the natural processes of hand papermaking and analog printing to create these imperfections, I can embrace and redefine my own. Through paper making and analog printing, I can embrace my own imperfections, redefine them, and find beauty in them.
