Bed nucleus of the stria terminalis and amygdala responses to unpredictable threat in children.

Substantial evidence from studies in humans suggests the amygdala is pivotal for anxiety. Findings from animal models and translational studies suggests the bed nucleus of the stria terminalis (BNST) is also critical for anxiety and the anticipation of unpredictable threat in adults. However, it remains unknown whether the BNST is involved in unpredictable threat anticipation in children. Forty-two 8-10-year-olds completed resting-state functional magnetic resonance imaging (fMRI) scans and an unpredictable threat fMRI task in which they were trained to associate cues with images. Intrinsic connectivity analyses were performed to establish functional BNST and amygdala networks. BNST and amygdala activation to cues and images was tested. Significant findings were followed by task-based functional connectivity analyses. Children showed evidence for BNST and amygdala intrinsic connectivity that was similar to previous patterns observed in adults. In response to unpredictable cues relative to neutral face cues, children had a significant amygdala response but no response in the BNST. The amygdala, but not the BNST, also showed a significantly greater response to fear face images relative to neutral images. Thus, unpredictable threat activated the amygdala, but not BNST, in children. This finding is contrary to studies showing robust BNST activation to unpredictable threat in adults and may suggest that the BNST's role in threat processing emerges later in development.

Responding to a Tragedy: Evaluation of a Postvention Protocol Among Adult Psychiatry Residents.

OBJECTIVE: In a time of "zero suicide" initiatives and rising suicide rates, resident physicians are particularly susceptible to the psychological and professional ramifications of patient suicide. An adult psychiatry residency program developed and implemented a postvention protocol to address the impact of patient suicide among resident physicians. The current study is a formal evaluation of a training program's postvention protocol from June 2018 to April 2020. METHODS: Process and outcome indicators were identified to assess protocol implementation and effectiveness. Process indicators included were postvention protocol adherence. Outcome indicators were perceived helpfulness of postvention protocol-related supports, occupational and general health measures, posttraumatic growth, and posttraumatic stress symptoms following resident participation in the postvention protocol. RESULTS: Study response rate was 97% (n = 57/59) and 81% completed the entire survey (n = 48/59). Twenty percent of residents (n = 10/48) experienced patient suicide during residency. Postvention protocol adherence was between 57 and 100%. Protocol-related supports, such as speaking with attendings who had previously experienced an adverse event, were more helpful than other supports (p < 0.01). Compared to residents who had not experienced patient suicide, mean work empowerment, burnout, mental health, and quality of life scores were not significantly different from residents who participated in the postvention protocol (p > 0.05). Posttraumatic growth was positively correlated with self-determination at work (p = 0.01). CONCLUSIONS: The postvention protocol was helpful to residents and potentially effective at mitigating the psychological and professional consequences of patient suicide. Study findings may inform standardization of postvention protocols among psychiatry training programs.

Independent Preoperative Predictors of Prolonged Length of Stay after Laparoscopic Appendectomy in Patients Over 30 Years of Age: Experience from a Single Institution.

Prompt discharge after laparoscopic appendectomy (LA) is a marker of quality of care, fiscally desirable and feasible in select patients. Patients over 30 comprise a more heterogeneous cohort known to experience worse outcomes after LA. We aimed to identify easily available preoperative risk factors portending a postoperative length of stay ≥2 days among patients above age 30. In this investigation, 296 included patients from a single institution who underwent LA for acute appendicitis from 2010 to 2014 were retrospectively reviewed for preoperative demographics, laboratory studies, comorbidities, presentation characteristics, radiographic finding, and other rationally selected factors for association with postoperative length of stay ≥2 days. Bivariate and multivariate analysis was conducted to determine independent risk factors, which were subsequently modeled via receiver-operating characteristic curve generation and Kaplan-Meier analysis. "Classic" presentation [odds ratio (OR) = 0.5, P = .02], elevated red cell distribution width (RDW; OR = 1.5/% increase, P = 0.004) as well as evidence of rupture on CT (OR = 6.9, P < 0.001) were independently associated with postoperative length of stay ≥ 2 days. Modeling length of stay using these factors generated an area under the curve of 0.713 ± 0.037. Kaplan-Meier analysis of "classic" presentation, elevated RDW, and evidence of rupture on CT through the fifth postoperative day generated log-rank P values of 0.02, 0.05, and ≤ 0.001, respectively. In summary, lack of "classic" presentation, elevated RDW, and CT evidence of rupture are novel risk factors for prolonged postoperative length of stay in LA patients over 30. These findings may help target patients most appropriate for prompt discharge.
