Randomized Controlled TrialSocial interactions in virtual reality exposure therapy: A proof-of-concept pilot study.
Research on virtual reality exposure therapy (VRET) has demonstrated good treatment efficacy with regards to several anxiety disorders. Yet, there is lack of knowledge about the value of integrating interaction between clients and virtual humans in VRET. Such interaction might prove effective in treating psychological complaints that involve social interactions, such as social anxiety. ⋯ These findings indicate that virtual reality technology that incorporates social interactions may be successfully applied for therapeutic purposes.

Randomized Controlled TrialImpact of regional femoral nerve block during general anesthesia for hip arthoplasty on blood pressure, heart rate and pain control: A randomized controlled study.
Adequate pain management is essential for preventing hemodynamic instability which can affect the perfusion of vital organs during the perioperative period, particularly in geriatric patients. For hip arthroplasty, peripheral nerve block is frequently used, limiting the adverse effects of opioid and non-opioid analgesics. ⋯ Femoral nerve block improved perioperative hemodynamic stability mostly likely attributable to an overall reduced sympathico adrenergic tone.
