Over 40% of neuropathic pain patients experience mood and cognitive disturbances, often showing reduced response to analgesics, with most affected individuals being female. This highlights the critical role of biological sex in pain-related affective and cognitive disorders, making it essential to understand the emotional and cognitive circuits linked to pain for improving treatment strategies. However, research on sex differences in preclinical pain models is lacking. ⋯ PERSPECTIVE: This manuscript reports the relevance of long-term investigations of sex differences in chronic pain. It shows differential development of somatosensory sensitivity, negative affective states and cognitive impairments in males and females. It emphasizes the importance of including subjects of both sexes in the investigation of pain-related mechanisms and therapeutic management.

Many adults with sickle cell disease experience chronic, nonvaso-occlusive pain that can benefit from nonpharmacological interventions available for use in the home setting. Virtual reality (VR) has been shown to be effective in decreasing pain in chronic pain conditions and may be useful for home-based self-management of chronic pain in sickle cell. However, the literature lacks studies examining this potential. ⋯ However, further investigations are warranted to mitigate the challenges and limitations associated with using VR in this capacity. PERSPECTIVE: Few evidence-based, nonpharmacological interventions exist for chronic pain in adults with sickle cell disease. This first qualitative, pilot study of in-home VR for chronic pain in adults with sickle cell disease suggests that VR interventions need further exploration as a nonpharmacological strategy for mitigating their pain in the home setting.
