Show moreBackground: Virtual reality exposure therapy (VRET) and augmented reality exposure therapy (ARET) are digitally assisted psychotherapies that potentially enhance posttraumatic stress disorder (PTSD) treatment by increasing a patient's sense of presence during exposure therapy. This study aimed to systematically review current evidence regarding the efficacy of VRET and ARET as PTSD treatment. Methods: A systematic electronic database search, a systematic quality assessment and two meta-analyses were conducted in accordance with PRISMA guidelines. Results: Eleven studies on the efficacy of VRET for PTSD (n = 438) were found, but no studies on the efficacy of ARET. The majority of VRET studies were of a low quality and had heterogeneous results. Meta-analyses showed VRET outperformed waitlist control (standardized mean difference -0.64 (95% CI -1.05 to -0.22)) while no significant difference was found between VRET and active treatment conditions (standardized mean difference -0.25 (95% CI -0.77 to 0.27)). Conclusion: VRET was superior to waitlist control groups and as effective as other psychotherapies. However, the results showed considerable heterogeneity due to the low number of studies and variety of VRET methods. VRET may be an effective alternative to current treatments and shows promise for the treatment of PTSD patients that have not responded to previous treatment. Future research should focus on high quality RCTs, including information on side effects and adverse events, with sufficient numbers of participants. This study recognizes a research gap regarding the efficacy of ARET, while it may have potential for PTSD treatment. Show less

Show moreAfter the implementation of standard first line chemotherapy with platinum and antifolates in pleural mesothelioma, patients are confronted with a need for second line treatment at relapse or progression. We conducted a systematic review of the literature for the activity, effectiveness and toxicity of second line treatment. The results are presented according to the class of drugs: chemotherapy and targeted or biological agent. (C) 2015 Elsevier Ireland Ltd. All rights reserved. Show less
