Virtual Reality for Sub-Acute Pain After Orthopedic Traumatic Musculoskeletal Injuries: A Mixed Methods Pilot Study.

OBJECTIVES: Acute orthopedic traumatic musculoskeletal injuries are prevalent, costly, and often lead to persistent pain and functional limitations. Psychological risk factors (pain catastrophizing and anxiety) exacerbate these outcomes but are often overlooked in acute orthopedic care. Addressing gaps in current treatment approaches, this mixed methods pilot study explored the use of a therapeutic virtual reality (VR; RelieVRx), integrating mindfulness and cognitive behavioral therapy, for pain self-management at home following orthopedic injury. METHODS: We enrolled 10 adults with recent orthopedic injuries and elevated pain catastrophizing or pain anxiety from Level 1 Trauma Clinics within the Mass General Brigham healthcare system. Participants completed daily RelieVRx sessions at home for 8 weeks, which included pain education, relaxation, mindfulness, games, and dynamic breathing biofeedback. Primary outcomes were a-priori feasibility, appropriateness, acceptability, satisfaction, and safety. Secondary outcomes were pre-post measures of pain, physical function, sleep, depression, and mechanisms (pain self-efficacy, mindfulness, and coping). RESULTS: The VR and study procedures met or exceeded all benchmarks. We observed preliminary improvements in pain, physical functioning, sleep, depression, and mechanisms. Qualitative exit interviews confirmed high satisfaction with RelieVRx and yielded recommendations for promoting VR-based trials with orthopedic patients. DISCUSSION: The results support a larger randomized clinical trial of RelieVRx versus a sham placebo control to replicate the findings and explore mechanisms. There is potential for self-guided VR to promote evidence-based pain management strategies and address the critical mental health care gap for patients following acute orthopedic injuries.

Pre-Younger Dryas megafaunal extirpation at Rancho La Brea linked to fire-driven state shift.

The cause, or causes, of the Pleistocene megafaunal extinctions have been difficult to establish, in part because poor spatiotemporal resolution in the fossil record hinders alignment of species disappearances with archeological and environmental data. We obtained 172 new radiocarbon dates on megafauna from Rancho La Brea in California spanning 15.6 to 10.0 thousand calendar years before present (ka). Seven species of extinct megafauna disappeared by 12.9 ka, before the onset of the Younger Dryas. Comparison with high-resolution regional datasets revealed that these disappearances coincided with an ecological state shift that followed aridification and vegetation changes during the Bølling-Allerød (14.69 to 12.89 ka). Time-series modeling implicates large-scale fires as the primary cause of the extirpations, and the catalyst of this state shift may have been mounting human impacts in a drying, warming, and increasingly fire-prone ecosystem.

Psychological resiliency explains the relationship between emotional distress and quality of life in neurofibromatosis.

PURPOSE: Neurofibromatoses (NF; NF1, NF2, and schwannomatosis) are incurable tumor suppressor syndromes with heterogeneous symptoms. Emotional distress (e.g., depression, anxiety, stress) is common in NF and impairs quality of life (QoL). Several modifiable dimensions of resiliency can contribute to enhanced QoL in medical populations but have been overlooked as treatment mechanisms for NF. Our goal was to determine, using data from an ongoing efficacy RCT testing a mind-body program for NF, if resiliency explains the relationship between emotional distress and QoL. METHODS: We performed structural equation modeling mediation analysis on baseline measures of QoL (physical health, psychological, social relationships, environmental), emotional distress (depression, anxiety, stress), and resiliency (gratitude, optimism, coping, mindfulness, empathy) completed by adults with NF (N = 228). We controlled for variables known to impact psychosocial functioning in NF (age, diagnosis, learning disability, and education). RESULTS: After adjusting for covariates, resiliency had a significant and large indirect effect on the negative relationship between emotional distress and QoL (CSIE = - 0.31, 95% CI = - 0.59 to - 0.19, p = .001). The direct effect of emotional distress on QoL was smaller but remained significant (ß = - 0.23, 95% CI = - 0.44 to - 0.03, p = .03), suggesting partial mediation through resiliency. CONCLUSIONS: Resiliency may buffer the high rates of emotional distress in NF. Mind-body interventions targeting multiple modifiable resiliency factors may be a promising path toward promoting QoL in adults with NF.
