Patients with chronic pain often experience exaggerated pain response and aversive emotion, such as anxiety and depression. Central plasticity in the anterior cingulate cortex (ACC) is assumed to be a critical interface for pain perception and emotion, which has been reported to involve activation of NMDA receptors. Numerous studies have documented the key significance of cGMP-dependent protein kinase I (PKG-I) as a crucial downstream target for the NMDA receptor-NO-cGMP signaling cascade in regulating neuronal plasticity and pain hypersensitivity in specific regions of pain pathway, ie, dorsal root ganglion or spinal dorsal horn. ⋯ Further mechanistic analysis revealed that PKG-I might act to phosphorylate TRPC3 and TRPC6, leading to enhancement of calcium influx and neuronal hyperexcitability as well as synaptic potentiation, which results in the exaggerated pain response and comorbid anxiety and depression. We believe this study sheds new light on the functional capability of ACC-PKG-I in modulating chronic pain as well as pain-associated anxiety and depression. Hence, cingulate PKG-I may represent a new therapeutic target against chronic pain and pain-related anxiety and depression.

Fibrotic-Like Pulmonary Radiographic Patterns Are Not Associated With Adverse Outcomes in COVID-19 Chronic Critical Illness.
Pulmonary fibrosis is a feared complication of COVID-19. To characterize the risks and outcomes associated with fibrotic-like radiographic abnormalities in patients with COVID-19-related acute respiratory distress syndrome (ARDS) and chronic critical illness. ⋯ Approximately half of adults with COVID-19-associated chronic critical illness have fibrotic-like patterns that are associated with higher interleukin-6 levels at intubation. Fibrotic-like patterns are not associated with longer time to liberation from mechanical ventilation or worse 6-month survival.

Active Day Patient Treatment (ADAPT) is a well-established 3 week intensive cognitive-behavioural, interdisciplinary pain management program for patients with disabling chronic pain. The aim of this analysis was to conduct an economic analysis of patient-related effects of ADAPT using hospital administrative data, specifically, to compare the costs and health outcomes for patients 1 month after participating in the program, with the preprogram period when they were receiving standard care. This retrospective cohort study included 230 patients who completed ADAPT (including follow-ups) between 2014 and 17 at the Pain Management and Research Centre at the Royal North Shore Hospital in Sydney, Australia. ⋯ The cost per clinically meaningful change in pain severity and interference score based on the BPI severity and BPI interference were AU$9452.32 (95% CI: $7031.76-$12,930.40) and AU$3446.62 (95% CI: $2851.67-$4126.46), respectively. The cost per point improvement and per clinically meaningful change in the Pain Self-efficacy Questionnaire were $483 (95% CI: $411.289-$568.606) and $3381.02, respectively. Our analysis showed a better health outcome, reduced healthcare services' cost, and reduced number of medications taken 1 month after participating in ADAPT.

Chronic pain has economic costs on par with cardiovascular disease, diabetes, and cancer. Despite this impact on the health care system and increasing awareness of the relationship between pain and mortality, efforts to identify simple symptom-based risk factors for the development of pain, particularly in children, have fallen short. This is critically important as pain that manifests during childhood often persists into adulthood. To date, no longitudinal studies have examined symptoms in pain-free children that presage a new, multisite manifestation of pain in the future. We hypothesized that female sex, sleep problems, and heightened somatic symptoms complaints at baseline would be associated with the risk of developing new multisite pain 1 year later. ⋯ Identifying symptom-based risk factors for multisite pain in children is critical for early prevention. Somatic awareness, sleep and attention problems represent actionable targets for early detection, treatment, and possible prevention of multisite pain in youth.
