A single-site pilot feasibility randomized trial of a supportive care mobile application intervention for patients with advanced cancer and caregivers.

PURPOSE: Mobile health interventions can improve patient care. We developed the Digital Supportive Care Awareness and Navigation (D-SCAN) application (app) to facilitate symptom monitoring and use/awareness of cancer supportive care resources. This study tested feasibility, usability/satisfaction, and preliminary efficacy of D-SCAN. METHODS: We randomized 50 patients with advanced cancer to receive the D-SCAN intervention or usual care; 10 caregivers also received D-SCAN. The primary feasibility outcome was determined by weekly symptom survey completion and end of study procedures. We assessed secondary outcomes including usability/satisfaction, awareness/use of supportive care resources, patient activation, and quality of life via various questionnaires including the Net Promoter Score (NPS), Patient Activation Measure (PAM-13), Functional Assessment of Cancer Therapy-General (FACT-G), and Caregiver Oncology Quality of Life (CarGOQOL) questionnaire. RESULTS: Seventy-six percent of intervention patients met feasibility criteria, exceeding our pre-determined threshold of 75%. Usability/satisfaction by NPS was high, at 14.3% and 12.5% for patients and caregivers, respectively. Intervention patient and caregiver resource awareness increased by a mean of 3.7 (p = 0.27) and 4.1 items, respectively. Supportive care resource utilization increased by a mean of 0.8 items for intervention patients (p = 0.70) and 0.6 for caregivers. PAM-13 increased by a mean of 1.6 for intervention patients (p = 0.65). FACT-G increased by a mean of 1.1 for intervention patients (p = 0.91), and CarGOQoL increased by a mean of 2.2 (p = 0.41). CONCLUSION: D-SCAN is a feasible, usable, and satisfactory intervention for augmenting patient and caregiver supportive care. Further testing is necessary to formally assess D-SCAN's efficacy and impact on patients and caregivers. CLINICAL TRIAL REGISTRATION NUMBER: NCT03628794. Registered on August 14th, 2018.

Adversity in childhood linked to elevated striatal dopamine function in adulthood.

Childhood adversity increases the risk of psychosis in adulthood. Theoretical and animal models suggest that this effect may be mediated by increased striatal dopamine neurotransmission. The primary objective of this study was to examine the relationship between adversity in childhood and striatal dopamine function in early adulthood. Secondary objectives were to compare exposure to childhood adversity and striatal dopamine function in young people at ultra high risk (UHR) of psychosis and healthy volunteers. Sixty-seven young adults, comprising 47 individuals at UHR for psychosis and 20 healthy volunteers were recruited from the same geographic area and were matched for age, gender and substance use. Presynaptic dopamine function in the associative striatum was assessed using 18F-DOPA positron emission tomography. Childhood adversity was assessed using the Childhood Experience of Care and Abuse questionnaire. Within the sample as a whole, both severe physical or sexual abuse (T63=2.92; P=0.005), and unstable family arrangements (T57=2.80; P=0.007) in childhood were associated with elevated dopamine function in the associative striatum in adulthood. Comparison of the UHR and volunteer subgroups revealed similar incidence of childhood adverse experiences, and there was no significant group difference in dopamine function. This study provides evidence that childhood adversity is linked to elevated striatal dopamine function in adulthood.
