Health Professions Faculty Beliefs, Confidence, Use, and Perceptions of Organizational Culture and Readiness for EBP: A Cross-sectional, Descriptive Survey

Background: Evidence-based practice (EBP) is an essential skill and ethical obligation for all practicing health professions clinicians because of its strong association with improved health outcomes. Emerging evidence suggests that faculty who prepare these clinicians lack proficiency to teach EBP

Effect of Childhood Trauma on Adult Depression and Neuroendocrine Function: Sex-Specific Moderation by CRH Receptor 1 Gene

Variations of the corticotropin-releasing hormone receptor 1 (CRHR1) gene appear to moderate the development of depression after childhood trauma. Depression more frequently affects women than men. We examined sex differences in the effects of the CRHR1 gene on the relationship between childhood trauma and adult depression. We recruited 1,063 subjects from the waiting rooms of a public urban hospital. Childhood trauma exposure and symptoms of depression were assessed using dimensional rating scales. Subjects were genotyped for rs110402 within the CRHR1 gene. An independent sample of 78 subjects underwent clinical assessment, genotyping, and a dexamethasone/CRH test. The age range at recruitment was 18–77 years and 18–45, for the two studies respectively. In the hospital sample, the protective effect of the rs110402 A-allele against developing depression after childhood trauma was observed in men (N = 424), but not in women (N = 635). In the second sample, the rs110402 A-allele was associated with decreased cortisol response in the dexamethasone/CRH test only in men. In A-allele carriers with childhood trauma exposure women exhibited increased cortisol response compared men; there were no sex differences in A-allele carriers without trauma exposure. This effect may, however, not be related to gender differences per se, but to differences in the type of experienced abuse between men and women. CRHR × environment interactions in the hospital sample were observed with exposure to physical, but not sexual or emotional abuse. Physical abuse was the most common type of abuse in men in this cohort, while sexual abuse was most commonly suffered by women. Our results suggest that the CRHR1 gene may only moderate the effects of specific types of childhood trauma on depression. Gender differences in environmental exposures could thus be reflected in sex-specific CRHR1 × child abuse interactions

Content analysis of promotional material for asthma-related products and therapies on Instagram

BACKGROUND: Increasingly, social media is a source for information about health and disease self-management. We conducted a content analysis of promotional asthma-related posts on Instagram to understand whether promoted products and services are consistent with the recommendations found in the Global Initiative for Asthma (GINA) 2019 guidelines. METHODS: We collected every Instagram post incorporating a common, asthma-related hashtag between September 29, 2019 and October 5, 2019. Of these 2936 collected posts, we analyzed a random sample of 266, of which, 211 met our inclusion criteria. Using an inductive, qualitative approach, we categorized the promotional posts and compared each post\u27s content with the recommendations contained in the 2019 GINA guidelines. Posts were categorized as consistent with GINA if the content was supported by the GINA guidelines. Posts that promoted content that was not recommended by or was unrelated to the guidelines were categorized as not supported by GINA . RESULTS: Of 211 posts, 89 (42.2%) were promotional in nature. Of these, a total of 29 (32.6%) were categorized as being consistent with GINA guidelines. The majority of posts were not supported by the guidelines. Forty-one (46.1%) posts promoted content that was not recommended by the current guidelines. Nineteen (21.3%) posts promoted content that was unrelated to the guidelines. The majority of unsupported content promoted non-pharmacological therapies (n = 39, 65%) to manage asthma, such as black seed oil, salt-room therapy, or cupping. CONCLUSIONS: The majority of Instagram posts in our sample promoted products or services that were not supported by GINA guidelines. These findings suggest a need for providers to discuss online health information with patients and highlight an opportunity for providers and social media companies to promote evidence-based asthma treatments and self-management advice online

Neural Correlates of Attention Bias to Threat in Post-traumatic Stress Disorder

Attention bias has been proposed to contribute to symptom maintenance in Posttraumatic Stress Disorder (PTSD), although the neural correlates of these processes have not been well defined. When engaging in tasks that require attention, individuals with PTSD have demonstrated altered activity in brain regions such as the dorsolateral prefrontal cortex (dlPFC), anterior cingulate cortex (ACC), ventrolateral prefrontal cortex (vlPFC), and amygdala; however, few PTSD neuroimaging studies have employed tasks that both measure attentional strategies being engaged and included emotionally-salient information, which was the goal of the present study. We administered a modified attention bias task, the dot probe, which is equipped to measure direction and magnitude of bias, to a sample of 37 (19 trauma control, 18 PTSD+) traumatized African-American adults during functional magnetic resonance imaging. Compared to traumatized participants without PTSD, PTSD+ participants demonstrated increased activation in the dlPFC in response to trials including angry/threatening expressions. In addition, attentional avoidance of threat cues corresponded with increased vlPFC and dorsal ACC (dACC) activation in the PTSD group, a pattern that was not observed in controls. These data provide some evidence to suggest that relative increases in dlPFC, dACC and vlPFC activation to threat cues in the context of heightened attentional demands represent neural markers of attentional bias for threat in individuals with PTSD, reflecting selective disruptions in attentional control and emotion processing networks in this disorder

Promoting higher order thinking skills in biology: evaluation of a newly developed course using Bloom’s taxonomy.

We have recently designed and implemented a unique, large (1800 students/year) first year biological concepts of health course (BIOL*1080) aimed at promoting higher order thinking skills and attributes. Our course served as one of three courses that replaced two more traditional biology courses (BIOL*1030 and BIOL*1040) and incorporates seminar, lab and interdisciplinary assignments in an attempt to foster skills in areas such as oral and written communication, critical thinking, and independent learning. To determine if we were successful in designing a course centered on the teaching and assessment of higher order thinking skills, we ranked the course evaluative materials based on Bloom’s taxonomy (Zheng, A.Y., Science 319:414,2008). Bloom’s taxonomy is a hierarchical categorization of knowledge and thinking skills comprised of 6 levels (from lowest to highest): knowledge - 1, comprehension – 2, application – 3, analysis – 4, synthesis – 5, and evaluation – 6. Briefly, each exam question and assignment was scored by a team of 6 individuals with varying degrees of familiarity with the course. Scores per test/assignment were averaged and a weighted average was calculated for the entire course, with a higher weighted average representing assessment of a higher order of thinking. The average bloom level for our course was 3.28±0.15 which was significantly higher than one of the more traditional biology courses (BIOL*1030 – 1.93±0.08 ) but not the second course (BIOL*1040 – 2.95±0.17). The blooming exercise provided a useful metric to assess the level of higher order thinking required for newly developed courses and allowed for comparisons between courses to be objective
