Randomized Controlled Trial
Pain response to cannabidiol in opioid-induced hyperalgesia, acute nociceptive pain, and allodynia using a model mimicking acute pain in healthy adults in a randomized trial (CANAB II).
Opioids in general and remifentanil in particular can induce hyperalgesia. Preclinical data suggest that cannabidiol might have the capacity to reduce opioid-induced hyperalgesia (OIH). Thus, we investigated the effect of oral cannabidiol on OIH in healthy volunteers using an established pain model. ⋯ Cannabidiol was well tolerated. We conclude that a high single-oral dose of 1600-mg cannabidiol is not effective in reducing OIH. Before excluding an effect of cannabidiol on OIH, research should focus on drug formulations enabling higher cannabidiol concentrations.

Randomized Controlled Trial
Respiratory effects of the atypical tricyclic antidepressant tianeptine in human models of opioid-induced respiratory depression.
Animal data suggest that the antidepressant and α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor modulator tianeptine is able to prevent opioid-induced respiratory depression. The hypothesis was that oral or intravenous tianeptine can effectively prevent or counteract opioid-induced respiratory depression in humans. ⋯ Neither oral nor intravenous tianeptine were respiratory stimulants. Intravenous tianeptine over the concentration range of 500 to 2000 ng/ml worsened respiratory depression induced by remifentanil.

Observational StudyCancer pain: Results of a prospective study on prognostic indicators of pain intensity including pain syndromes assessment.
Pain is a prevalent symptom in patients with advanced cancer. Recognition of prognostic factors associated with pain intensity, could help provide better assessment, leading to better pain management. ⋯ The recognition of specific pain syndromes may help to better classify cancer pain.

The United States faces a crisis because of the high prevalence of chronic pain, concurrent opioid use disorder, and overdose deaths. Prescription opioids remain a primary driver of opioid-related deaths. Craving is a core symptom of addiction, yet the degree to which craving plays a role in prescription opioid use among patients with chronic pain is unknown. ⋯ We also found that craving had a small association with morphine equivalent daily dose and pain severity but was more strongly associated with depression. Craving of prescription opioids among veterans with chronic pain is complex. Findings are discussed in relation to chronic pain symptoms, psychiatric comorbidities, and demographics.

Can You Hear Us Now? Equity in Global Advocacy for Palliative Care.
Evidence-based advocacy underpins the sustainable delivery of quality, publicly guaranteed, and universally available palliative care. More than 60 million people in low- and middle-income countries (LMICs) have no or extremely limited access to either palliative care services or essential palliative care medicines (e.g., opioids) on the World Health Organization Model List. Indeed, only 12% of the global palliative care need is currently being met. ⋯ Their advocacy is situated in the context of an emerging global health narrative that stipulates palliative care provision as an ethical obligation of all health systems. To support advocacy efforts, palliative care evaluation and indicator data should assess the extent to which LMIC practitioners lead and participate in global and regional advocacy. This goal entails investment in transnational advocacy initiatives, research investments in palliative care access and cost-effective models in LMICs, and capacity building for a global community of practice to capture the attention of policymakers at all levels of health system governance.
