The International Classification of Diseases (ICD) and the Diagnostic and Statistical Manual (DSM) are routinely used in diagnosing illicit substance use disorders, but for people taking prescribed opioids they remain controversial. In pain medicine, the concept of "Addiction" is preferred with reduced emphasis on tolerance and withdrawal. This article examines the prevalence and characteristics of pharmaceutical opioid dependence/disorder according to ICD, DSM, and the pain medicine concept of "Addiction," among chronic noncancer pain (CNCP) patients prescribed opioids. ⋯ Participants meeting the criteria for "Addiction" only were older, less likely to engage in nonadherent behaviours, self-reported fewer problems or concerns with their medication, and had lower rates of psychological distress than those who also met the DSM-5 and ICD-11 criteria. The definition of "Addiction" captures a larger group of patients than other classification systems and includes people with fewer "risk" behaviours. Despite removal of tolerance and withdrawal for prescribed opioid use for DSM-5, we found that "Addiction" was more closely related to an ICD-11 diagnosis of pharmaceutical opioid dependence.

Intracerebroventricular (ICV) administration of opioids for control of intractable cancer pain has been used since 1982. We present here our experience of intracerebroventricular administration of pain treatments including ziconotide associated with morphine and ropivacaine for patients resistant to a conventional approach, with nociceptive, neuropathic, or mixed pain. These clinical cases were conducted with patients suffering from refractory pain, more than 6/10 on a numerical pain rating scale (NPRS) while on high-dose medical treatment and/or intolerance with significant side effects from oral medication. ⋯ Minor side effects were initially observed but transiently. One psychiatric agitation required discontinuation of ziconotide infusion. For intractable pain, using ziconotide by intracerebroventricular infusion seems safe and efficient, specifically for chronic neoplastic pain of cervicocephalic, thoracic, or diffuse origin and also for pain arising from a central neuropathic mechanism.

Derivation of Novel Risk Prediction Scores for Community-Acquired Sepsis and Severe Sepsis.
We sought to derive and internally validate a Sepsis Risk Score and a Severe Sepsis Risk Score predicting future sepsis and severe sepsis events among community-dwelling adults. ⋯ The Sepsis Risk Score and Severe Sepsis Risk Score predict 10-year sepsis and severe sepsis risk among community-dwelling adults and may aid in sepsis prevention or mitigation efforts.

Mapping Thalamocortical Functional Connectivity in Chronic and Early Stages of Psychotic Disorders.
There is considerable evidence that the thalamus is abnormal in psychotic disorders. Resting-state functional magnetic resonance imaging has revealed an intriguing pattern of thalamic dysconnectivity in psychosis characterized by reduced prefrontal cortex (PFC) connectivity and increased somatomotor-thalamic connectivity. However, critical knowledge gaps remain with respect to the onset, anatomical specificity, and clinical correlates of thalamic dysconnectivity in psychosis. ⋯ Thalamocortical dysconnectivity is present in both chronic and early stages of psychosis, includes reduced thalamic connectivity with the executive control network, and is related to cognitive impairment.
