Objectives: Prior studies demonstrate elevated cortical glutamate (Glu) in patients with bipolar disorder (BD). Studies assessing neurochemistry in early stages of bipolar illness before the emergence of manic symptoms are lacking. This study aimed to examine neurochemical correlates measured by proton magnetic resonance spectroscopy ( 1 H-MRS) and a dimensional measure of bipolarity in a sample of depressed adolescents. Methods: Adolescent participants (aged 13–21 years) underwent a semistructured diagnostic interview and clinical assessment, which included the General Behavior Inventory Parent Version (P-GBI), a 73-item, parent-rated assessment of symptoms and behaviors. 1 H-MRS scans of a left dorsolateral prefrontal cortex (L-DLPFC) voxel (8 cm 3 ) were collected using a two-dimensional J -averaged sequence to assess N -acetylaspartate (NAA), Glu, Glx (glutamate + glutamine), and NAA/Glx concentrations. We used generalized linear models to assess the relationships between P-GBI scores and metabolite levels in L-DLPFC. Results: Thirty-six participants (17 healthy controls, 19 depressed) underwent 1 H-MRS scans and clinical evaluation with the P-GBI. There was a significant negative relationship between P-GBI score and L-DLPFC NAA/Glx in the whole sample. However, the magnitude of the effect was small and statistical significance was lost after correcting for multiple comparisons. Conclusions: These preliminary results suggest that NAA/Glx may have utility as a marker of bipolar traits in healthy and depressed adolescents. If replicated, 1 H-MRS measures of glutamatergic metabolism anomalies might have a role in identifying depressed adolescents at risk for mixed symptom presentations or BD. Identifying bipolarity in the early stages of the disease would have a significant impact on treatment planning and prognosis. Further longitudinal studies should examine neurochemical correlates of mood state during the developmental emergence of BD.

550 Background: Ductal carcinoma in situ (DCIS) is a heterogeneous group of non-invasive cancers with varying propensity for recurrence. There are no validated markers that identify patients at risk for invasive recurrence following lumpectomy. HOXB13/IL17BR (H/I) is expressed in both DCIS and invasive cancer (Ma Cancer Cell. 2004) and associated with recurrence in stage I cancer. A 5-gene molecular grade index (MGI) distinguishes outcome in grade II disease (Ma Clin Cancer Res. 2008). We sought to determine whether H/I or MGI was associated with invasive recurrence in resected DCIS. Methods: We identified patients at Mayo Rochester who underwent lumpectomy ± radiation for DCIS between 1988 and 2001 and performed a nested case/control study. Cases were patients with ipsilateral invasive recurrence, matched to controls based on age, surgery date, length of follow-up, and adjuvant radiation. DCIS was macrodissected from paraffin sections and RNA extracted to obtain H/I and MGI RT-PCR profiles. The association of H/I and MGI with case-control status was assessed with conditional logistic regression; results reported are odds ratios (OR) with 95% confidence intervals (CI). The association of H/I and MGI as continuous variables with nuclear grade (low, intermediate, high) was estimated with Spearman's rank correlation. Results: 427 patients underwent lumpectomy for DCIS, and 33 were identified as possible cases. Histologic review excluded 8 (non-sufficient tissue or DCIS recurrence without invasion). 25 cases were matched to 48 controls (2 controls for 23 cases, 1 control for 2 cases). Both H/I (r = 0.43, p = 0.0001) and MGI (r = 0.41, p = 0.0004) were significantly correlated with nuclear grade. Positive H/I was associated with trend towards higher recurrence (OR 1.9; p = 0.22) that was most pronounced in cases/controls (15/28) treated with lumpectomy alone (OR 3.3; CI: 0.8–13.2, p = 0.09). Similarly, positive MGI was associated with a trend towards higher recurrence risk in patients treated with surgery alone (OR 2.0; CI: 0.6–6.4, p = 0.27). Conclusions: These data suggest that both HOXB13/IL17BR and MGI can identify a subset of patients with surgically resected DCIS who are at risk for invasive recurrence. Further studies in larger cohorts are needed to confirm these findings. [Table: see text]

Abstract Informed consent, enshrined in many of the codes of conduct of psychology and psychiatry professional organizations, is an integral component behind the ethical practice of psychotherapy. Foundationally, informed consent respects patient autonomy and should be a knowledge sharing process that allows patients greater agency and improved alliance with their clinician. Psychotherapy differs from medical and surgical interventions in that it is a longitudinal, collaborative, and interpersonal treatment. As many psychotherapists are not trained in traditional medical models of care, a medically based framework for informed consent may not be as familiar and appropriate for psychotherapy. These nuances do not diminish the need for informed consent but rather emphasize the distinctiveness of psychotherapy and necessity of adapting to this treatment modality. In this chapter, the informed consent process for psychotherapy is examined, detailing its historical development, legal and ethical foundations, as well as the subtleties and challenges regarding implementation.

Background: Emergency departments (EDs) have recognized an increasing number of patients presenting with mental health (MH) concerns. This trend imposes greater demands upon EDs already operating at capacity. Many ED providers do not feel they are optimally prepared to provide the necessary MH care. One consideration in response to this dilemma is to use advanced telemedicine technology for psychiatric consultation. Introduction: We examined a rural- and community-based health system operating 21 EDs, none of which has direct access to psychiatric consultation. Dedicated beds to MH range from zero (in EDs with only 3 beds) to 6 (in an ED with 38 beds). Materials and Methods: We conducted a needs assessment of this health system. This included a survey of emergency room providers with a 67% response rate and site visits to directly observe patient flow and communication with ED staff. A visioning workshop provided input from ED staff. Data were also obtained, which reflected ED admissions for the year 2015. Results: The data provide a summary of provider concerns, a summary of MH presentations and diagnosis, and age groupings. The data also provide a time when most MH concerns present to the ED. Discussion: Based upon these results, a proposed model for delivering comprehensive regional emergency telepsychiatry and behavioral health services is proposed. Conclusions: Emergency telepsychiatry services may be a tenable solution for addressing the shortage of psychiatric consultation to EDs in light of increasing demand for MH treatment in the ED.
