Utility of in-session assessments during cognitive behavioral therapy for depression after traumatic brain injury: Results from a randomized controlled trial.

BACKGROUND: The development of depression after moderate to severe traumatic brain injury (TBI) is common. Cognitive-behavioral therapy (CBT) can be used to treat post-TBI depression, but the symptoms response is poorly described. OBJECTIVE: This secondary analysis assessed: (1) the trajectory of depression symptoms up to 12 sessions of CBT, (2) which depressive symptom clusters were responsive to in-person and phone CBT, and (3) whether interim depression thresholds predict 16-week treatment response. METHOD: This secondary analysis of the IRB-approved Life Improvement Following Traumatic Brain Injury trial included 100 adults with major depressive disorder (MDD) within ten years of moderate to severe traumatic brain injury from throughout the US. We used a combination of descriptive, graphical, and diagnostic accuracy methods. RESULTS: Cardinal and cognitive-affective symptom clusters improved most from CBT over 16 weeks. At 8 and 16 weeks, the most responsive individual symptoms were anhedonia, depressed mood, and fatigue; the least responsive were sleep and appetite. PHQ-9 thresholds with a Negative Predictive Value greater than 0.7 for sessions 6, 7, and 8 were, respectively: >15, >10, and >9. CONCLUSION: In-person and phone CBT led to similar symptom responses during treatment. Additionally, using PHQ-9 thresholds for predicting intervention response within eight sessions may help identify the need for treatment adjustments.

Psychiatry's Expanded Integration into Primary Care.

Integrated behavioral care, and in particular, the collaborative care model, has been working to improve access and treatment for people with mental health disorders. Integrated care allows for adaptable, scalable, and sustainable practice that addresses the mental health needs of the public. During the pandemic several challenges emerged to delivering integrated care. This disruption happened at a systems level, team-based care level, scope of care level, and patient access level. This article looks through the lens of those various levels to identify and some of the lessons learned to help build a more resilient and flexible integrated care program.

Development and Implementation of an Integrated Care Fellowship.

BACKGROUND: Integrated care is a common approach to leverage scarce psychiatric resources to deliver mental health care in primary care settings. OBJECTIVE: Describe a formal clinical fellowship devoted to professional development for the integrated care psychiatrist role. METHODS: The development of a formal year-long clinical fellowship in integrated care is described. The curriculum consists of an Integrated Care Didactic Series, Integrated Care Clinical Skill Experiences, and Integrated Care System-Based Leadership Experiences. Evaluation of impact was assessed with descriptive statistics. RESULTS: We successfully recruited 3 classes of fellows to the Integrated Care Fellowship, with 5 program graduates in the first 3 years. All 5 graduated fellows were hired into integrated care and/or telepsychiatry positions. Integrated Care fellows had a high participation rate in didactics (mean attendance = 80.6%; n = 5). We received a total of 582 didactic evaluations for the 151 didactic sessions. On a scale of 1 (poor) to 6 (fantastic), the mean quality of the interactive learning experience was rated as 5.33 (n = 581) and the mean quality of the talk was 5.35 (n = 582). Rotations were rated with the mean overall teaching quality of 4.98/5 (n = 76 evaluations from 5 fellows). CONCLUSIONS: The Integrated Care clinical fellowship serves as a model for training programs seeking to provide training in clinical and systems-based skills needed for practicing integrated care. Whether such training is undertaken as a standalone fellowship or incorporated into existing consultation-liaison psychiatry programs, such skills are increasingly valuable as integrated care becomes commonplace in practice.

Challenge at the Intersection of Race and Kink: Racial Discrimination, Fetishization, and Inclusivity Within the BDSM (Bondage-Discipline, Dominance-Submission, and Sadism-Masochism) Community.

The bondage-discipline, dominance-submission, and sadism-masochism (BDSM) community has achieved diversity with respect to gender identity and sexual orientation yet does so to a lesser extent with respect to race and ethnicity. A total of 398 BDSM practitioners recruited in 2018 and 2019 from BDSM conferences located within the Southern, Midwestern, and Western regions of the U.S., as well as online, completed surveys asking about racial and ethnic discrimination, fetishization, and inclusivity. People of color were 16 times more likely than non-people of color to feel discriminated against at BDSM events and 17 times more likely to feel fetishized. Qualitative results included troubling stories of overt racism and offensive racial slurs, and examples of microaggressions, feelings of isolation, and feelings of being dismissed. The results suggest that organizations can increase inclusivity by understanding the unique costs faced by people of color with an awareness that these costs might be invisible to non-people of color, diversifying positions of authority and leadership, and teaching well-meaning members what types of behaviors could create a hostile environment.

Health Effects and Sources of Prebiotic Dietary Fiber.

Prebiotic dietary fibers act as carbon sources for primary and secondary fermentation pathways in the colon, and support digestive health in many ways. Fructooligosaccharides, inulin, and galactooligosaccharides are universally agreed-upon prebiotics. The objective of this paper is to summarize the 8 most prominent health benefits of prebiotic dietary fibers that are due to their fermentability by colonic microbiota, as well as summarize the 8 categories of prebiotic dietary fibers that support these health benefits. Although not all categories exhibit similar effects in human studies, all of these categories promote digestive health due to their fermentability. Scientific and regulatory definitions of prebiotics differ greatly, although health benefits of these compounds are uniformly agreed upon to be due to their fermentability by gut microbiota. Scientific evidence suggests that 8 categories of compounds all exhibit health benefits related to their metabolism by colonic taxa.

Fermentability of Novel Type-4 Resistant Starches in In Vitro System.

Resistant starches are non-digestible starches that are fermented in the colon by microbiota. These carbohydrates are prebiotic and can be beneficial to consumer health. Many types of resistant starch exist with varying physical properties that may result in differences in fermentability. The objective of this research project was to compare potential prebiotic effects and fermentability of four novel resistant starches using an in vitro fermentation system and measuring changes in total gas production, pH, and formation of SCFAs (short chain fatty acids). Fecal donations were collected from seven healthy volunteers. Four novel resistant starches, modified potato starch (MPS), modified tapioca starch (MTS), and modified maize starches (MMS-1 and MMS-2), were analyzed and compared to polydextrose and short chain fructooligosaccharides (FOS) as controls. After twenty-four hours of fermentation, MPS and MTS responded similarly in gas production (74 mL; 70.6 mL respectively), pH (5.93; 5.93 respectively), and SCFA production (Acetate: 115; 124, Propionate: 21; 26, Butyrate: 29; 31 µmol/mL respectively). While MMS-1 had similar gas production and individual SCFA production, the pH was significantly higher (6.06). The fermentation of MMS-2 produced the least amount of gas (22 mL), with a higher pH (6.34), and lower acetate production (78.4 µmol/mL). All analyzed compounds were fermentable and promoted the formation of beneficial SCFAs.

Prebiotic Dietary Fiber and Gut Health: Comparing the in Vitro Fermentations of Beta-Glucan, Inulin and Xylooligosaccharide.

Prebiotic dietary fiber supplements are commonly consumed to help meet fiber recommendations and improve gastrointestinal health by stimulating beneficial bacteria and the production of short-chain fatty acids (SCFAs), molecules beneficial to host health. The objective of this research project was to compare potential prebiotic effects and fermentability of five commonly consumed fibers using an in vitro fermentation system measuring changes in fecal microbiota, total gas production and formation of common SCFAs. Fecal donations were collected from three healthy volunteers. Materials analyzed included: pure beta-glucan, Oatwell (commercially available oat-bran containing 22% oat ß-glucan), xylooligosaccharides (XOS), WholeFiber (dried chicory root containing inulin, pectin, and hemi/celluloses), and pure inulin. Oatwell had the highest production of propionate at 12 h (4.76 µmol/mL) compared to inulin, WholeFiber and XOS samples (p < 0.03). Oatwell's effect was similar to those of the pure beta-glucan samples, both samples promoted the highest mean propionate production at 24 h. XOS resulted in a significant increase in the genus Bifidobacterium after 24 h of fermentation (0 h:0.67 OTUs (operational taxonomic unit); 24 h:5.22 OTUs; p = 0.038). Inulin and WholeFiber increased the beneficial genus Collinsella, consistent with findings in clinical studies. All analyzed compounds were fermentable and promoted the formation of beneficial SCFAs.

Decisional and Dispositional Capacity Determinations: Neuropsychiatric Illness and an Integrated Clinical Paradigm.

BACKGROUND: Assessment of decisional capacity requires thorough clinical review of a patient's current psychiatric symptoms and cognitive processes. The assessment to determine the patient's capacity for self-management postdischarge is a different clinical concept from decisional capacity. OBJECTIVES: Standardized guidelines for capacity determinations (both for informed consent and for disposition) would be helpful to clinicians, patients, and their caregivers. METHOD: The authors reviewed the recent clinical literature on neuropsychiatric illnesses associated with impaired decisional capacity, as well as for the term "dispositional capacity." RESULTS: Neurocognitive disorders and neurologic disorders are commonly associated with impaired decisional capacity; other psychiatric illnesses are less commonly associated. There were no articles identified that used the term "dispositional capacity" to describe a subtype of decisional capacity determination. No definition or guidelines for determination of dispositional capacity were found. CONCLUSIONS: Routine evaluation for neurocognitive disorders including standardized cognitive assessment should be included in decisional capacity determinations. There is a need for a new subtype of decisional capacity determination, for which we propose the term "dispositional capacity." This concept is introduced and defined. For dispositional capacity determinations, supplementation of the usual decisional capacity evaluation with in vivo demonstration of self-management skills is recommended. Decisional and dispositional capacity determination is conceptualized with a biopsychosociocultural approach and guidelines for standardized assessment are presented.
