Examining PTSD Symptoms and the Effectiveness of Group Therapy Among African American and Caucasian Veterans

Millions of Americans have served in the military, and improved survival rates in wars have increased the percentage of those who return home. Posttraumatic stress disorder (PTSD) is one of the most prevalent mental health diagnoses for veterans. Although few studies have examined the link, previous research as well as the minority stress model and transgenerational trauma theories, suggest that race may be associated with PTSD, particularly in military samples. The current study examined whether there were differences in PTSD symptomology (global and symptom cluster-specific) based on veterans’ race and whether group therapy effectively reduced symptoms of PTSD. Data were collected from male veterans who identified as non-Hispanic Caucasian or non-Hispanic African American (N = 450) and participated in a 10-week, combat-related, group therapy PTSD Recovery Program between 2010 and 2014. Participants completed the Posttraumatic Stress Disorder Checklist- Military version (PCL-M) measure at three time points (intake, pre-treatment, and post-treatment). Global PTSD symptoms and three of the four symptom clusters did not differ between African American and Caucasian participants at intake. However, the symptom cluster of re-experiencing was higher for African Americans compared to Caucasians at intake. Additionally, the Recovery Program led to a reduction in PCL-M scores. This symptom reduction occurred regardless of race, with neither racial group improving more than the other. Moreover, dropout rates for the Recovery Program were on par or better than those for other trauma-focused therapies. Although the overall racial and ethnic composition of groups was not related to most outcomes, the percentage of racial/ethnic minority members in groups was negatively associated with the number of sessions attended for Caucasians. Findings also indicated that the PCL-M demonstrated good psychometric properties in an African American sample. One implication from this study is that the current conceptualization and measurement of PTSD may be insufficient. It may be more helpful to examine specific PTSD symptom clusters, especially when assessing differences by race. The effectiveness of the PTSD Recovery Program supports alternative options to treating veterans with PTSD in the VA system. Last, it is important for therapists to consider the composition of groups when conducting group therapy

Between Philosophy and Art

Similarity and difference, patterns of variation, consistency and coherence: these are the reference points of the philosopher. Understanding experience, exploring ideas through particular instantiations, novel and innovative thinking: these are the reference points of the artist. However, at certain points in the proceedings of our Symposium titled, Next to Nothing: Art as Performance, this characterisation of philosopher and artist respectively might have been construed the other way around. The commentator/philosophers referenced their philosophical interests through the particular examples/instantiations created by the artist and in virtue of which they were then able to engage with novel and innovative thinking. From the artists’ presentations, on the other hand, emerged a series of contrasts within which philosophical and artistic ideas resonated. This interface of philosopher-artist bore witness to the fact that just as art approaches philosophy in providing its own analysis, philosophy approaches art in being a co-creator of art’s meaning. In what follows, we discuss the conception of philosophy-art that emerged from the Symposium, and the methodological minimalism which we employed in order to achieve it. We conclude by drawing out an implication of the Symposium’s achievement which is that a counterpoint to Institutional theories of art may well be the point from which future directions will take hold, if philosophy-art gains traction

Differences in Attitudes Towards People with Disabilities: Examining the Effects of the Presence of an Assistance Dog

Individuals with disabilities face various types of social stigma. Research suggests that the presence of an assistance dog leads to an increase in social interactions. The purpose of this study was to determine whether people’s attitudes toward individuals with disabilities differ when pairing that person with an assistance dog. Undergraduate students (N= 244) were randomly assigned to view an individual with a disability either alone or with an assistance dog. Participants rated their attitudes toward the individual, completed a newly developed Implicit Association Test, and answered behavioral intention questions. Results of a hierarchical multiple regression analysis indicated that individuals with more positives attitudes toward dogs had significantly more positive social attitudes toward the individual with a disability paired with a dog, after accounting for gender and dog ownership history. Additionally, individuals had an implicit bias toward an individual with a disability paired with an assistance dog over the individual alone

INteractive Virtual Expert-Led Skills Training: A Multi-Modal Curriculum for Medical Trainees

Background: Internationally, pediatric depression and suicide are significant issues. Additionally, in the context of the COVID-19 pandemic, pediatric mental health needs are rising astronomically. In light of Child & Adolescent Psychiatrist (CAP) subspecialist shortages in the United States (US), there is an increasing call for primary care physicians in Family Medicine and Pediatrics to address an increasingly broad variety of patient needs. Here we report on the development and preliminary evaluation of medical student and resident perceptions on the “INteractive Virtual Expert-led Skills Training” (INVEST) medical education curriculum, a virtual synchronous CAP curriculum employing active learning strategies, including expert-led discussion and video modeling, and discussion designed to meet those priorities., Methods: In a standardized 60-min training format, our curriculum leverages audience response system polling, video modeling of key clinical skills, and interactive discussion with an expert subspecialist, over a virtual video conferencing platform. The primary educational strategy relies on use of video modeling to demonstrate best practice with CAP led group discussion to solidify and explain important concepts. Five waves of medical students and residents (N = 149) participated in the INVEST curriculum and completed pre- and post-training surveys regarding knowledge and comfort in the management of pediatric patients with depression and suicidality., Results: Trainee participants reported significant positive gains in perceived likelihood of encountering pediatric suicidality as well as knowledge/comfort with depression screening and suicidality assessment in a primary care setting. Across some competency areas, there was an effect of medical learner level. Learners at lower levels generally reported the highest benefit. Medical students reported significant increases in their comfort interpreting and discussing positive depression screens and evidenced the greatest relative benefit in comfort with discussing suicidality., Conclusion: To our knowledge, INVEST is the first fully virtual, multimodal curriculum led by expert CAP subspecialists. Our findings suggest that INVEST shows promise for equipping medical learners with baseline knowledge for caring for patients with pediatric depression and suicidality. This synchronous, virtually delivered curriculum allows for critical training delivered to diverse medical learners regardless of geographic location, a particular benefit during the current COVID-19 pandemic

Acyl-coenzyme A synthetases in metabolic control

The 11 long-chain (ACSL) and very long chain acyl-coenzyme A (acyl-CoA) synthetases [(ACSVL)/fatty acid transport protein] are receiving considerable attention because it has become apparent that their individual functions are not redundant

Vitrified magnesia dissolution and its impact on plutonium residue processing

Aqueous chloride operations at the Los Alamos Plutonium Facility cannot directly dispose of acidic waste solutions because of compatibility problems with existing disposal lines. Consequently, all hydrochloric acid must be neutralized and filtered prior to exiting the facility. From a waste minimization standpoint, the use of spent magnesia pyrochemical crucibles as the acid neutralization agent is attractive since this process would take a stream destined for transuranic waste and use it as a reagent in routine plutonium residue processing. Since Los Alamos National Laboratory has several years of experience using magnesium hydroxide as a neutralizing agent for waste acid from plutonium processing activities, the use of spent magnesia pyrochemical crucibles appeared to be an attractive extension of this activity. In order to be competitive with magnesium hydroxide, however, size reduction of crucible shards had to be performed effectively within the constraints of glovebox operations, and acid neutralization time using crucible shards had to be comparable to neutralization times observed when using reagent-grade magnesium hydroxide. The study utilized non-plutonium-contaminated crucibles for equipment evaluation and selection and used nonradioactive acid solutions for completing the neutralization experiments. This paper discusses experience in defining appropriate size reduction equipment and presents results from using the magnesia crucibles for hydrochloric acid neutralization, a logical precursor to introduction into glovebox enclosures
