NCT02498925
The prevalence of major depressive disorder (MDD) is relatively low in childhood (i.e., 1-3%), but increases substantially during adolescence. By the age of 18, approximately 15% of adolescents will have experienced at least one episode of MDD. A growing body of research implicates abnormalities in reward circuitry as playing a critical role in the development and maintenance of depressive symptoms in adolescents. Importantly, these reward-circuitry abnormalities have been linked to anhedonia (i.e., decreased pleasure or blunted reactivity to rewarding stimuli). Behavioral Activation (BA) represents a promising - and relatively simple to deliver - nonpharmacologic intervention for adolescent depression, which has been shown to be at least as effective as Cognitive Behavioral Therapy (CBT) with regards to symptom reduction and lowering the risk of relapse in adult samples. More recently, promising data have emerged from the application of BA to depressed adolescents. BA can be conceptualized as a treatment directly targeting anhedonia. More specifically, BA targets anhedonia through behavioral change strategies aimed at gradually increasing patients' exposure to and engagement with rewarding stimuli and positively reinforcing experiences. Given this treatment focus, BA may be particularly beneficial for adolescents struggling with relatively elevated levels of anhedonic symptoms. Accordingly, the present study will examine the role of anhedonia and reward functioning in predicting treatment response in BA. In addition, analyses will be conducted examining the reward-related neural and behavioral mechanisms underlying anhedonic symptom improvement in BA.

This study will compare stereotactic body radiation therapy (SBRT) to trans-arterial chemoembolization (TACE) as a bridging strategy for patients with HCC undergoing liver transplantation. We propose that SBRT will be associated with longer time intervals between initial treatment and the need for retreatment, compared to TACE, as a "bridge" to liver transplantation in subjects with HCC.
