As an academic tertiary care interventional pain clinic, referrals are screened to ensure patients most likely to benefit from our services are accepted into the practice. The objective of this study is to assess for unconscious bias in the patient selection process. ⋯ While the screening process did not result in disparities across age, gender, race, or language preference, there was a statistical difference in patients identifying as Hispanic. As a result of this study, all patient identification has been removed from the review document to limit the likelihood of unconscious bias.

Transforaminal epidural steroid injections (TFESI) are widely used to alleviate lumbosacral radicular pain. Knowledge of the therapeutic outcomes of TFESI allows clinicians to elucidate therapeutic plans for managing lumbosacral radicular pain. Deep learning (DL) can outperform traditional machine learning techniques and learn from unstructured and perceptual data. A convolutional neural network (CNN) is a representative DL model. ⋯ We demonstrated that a CNN model trained, using whole lumbar spine sagittal T2-weighted MR images, could help determine outcomes after TFESI in patients with chronic lumbosacral radicular pain due to an HLD or spinal stenosis.

Morphine is one of the preferred drugs for the clinical treatment of pain. Both clinical and preclinical studies have reported sexual dimorphism in morphine analgesia. Different circulating levels of estrogen could be involved in sex differences in response to morphine analgesia. In our previous research, we found that capsaicin injection into the cervix of rats caused acute visceral pain that could be relieved by morphine. The role of estrogen in morphine analgesia in rats under uterine cervix pain and its underlying mechanisms remain to be explored. ⋯ This is the first evidence that spinal CaV1.2 is involved in estrogenic modulation of morphine antinociception in rats under uterine cervix pain. Our results will provide new ideas and references for estrogen-related differential prescription of opioids.

Neuroimaging investigations have already uncovered alterations to cerebral microstructural integrity in patients with fibromyalgia (FM). In the meantime, these patients commonly suffer from depression and anxiety. ⋯ Our results demonstrate that disrupted white matter microstructure in patients with FM is mainly restricted to tracts associated with pain sensory processing and motor control, adjusting for psychosocial factors. A considerable degree of difference in white matter characteristics may be explained by the patients with FM group's greater level of psychological distress.

Obstructive sleep apnea (OSA) is the most common form of sleep-disordered breathing. While patients on chronic opioids are at increased risk of sleep-disordered breathing, there is a lack of data on the relationship between opioid dose and OSA risk in particular. The STOP-Bang Questionnaire (SBQ) is a common screening tool for OSA, but it has not been well studied in patients on chronic opioid therapy. ⋯ We found no relationship between the opioid dose and the risk of OSA as measured by the SBQ score in this chronic opioid population. Opioids may be more associated with sleep apnea due to central rather than obstructive processes, and additional screening tools beyond the SBQ may be needed to better screen for sleep apnea in this population.
