Stereotactic radiosurgery (SRS) is effective for patients with medically refractory trigeminal neuralgia with a 75%-90% response rate. Consideration of the integral dose (ID) to the target nerve within the 50% isodose line was reported to help select prescription doses to maximize effectiveness and minimize bothersome numbness. The objective of this study was to externally validate the ID as a predictor of outcomes after SRS. ⋯ The ID did not predict recurrence-free survival or sensory dysfunction. Our observations suggest improved nerve coverage by the most powerful area of the isocenter, for instance, by targeting a narrower segment if feasible, could result in more durable pain relief. Further studies to validate these findings are needed.

Multicenter Study
Development and internal validation of a clinical risk tool to predict chronic postsurgical pain in adults: a prospective multicentre cohort study.
Chronic postsurgical pain (CPSP) is a highly prevalent condition. To improve CPSP management, we aimed to develop and internally validate generalizable point-of-care risk tools for preoperative and postoperative prediction of CPSP 3 months after surgery. A multicentre, prospective, cohort study in adult patients undergoing elective surgery was conducted between May 2021 and May 2023. ⋯ These models demonstrated good calibration and clinical utility. The primary CPSP model demonstrated fair predictive performance including 2 significant predictors. Derivation of a generalizable risk tool with point-of-care predictors was possible for the threshold-based CPSP models but requires independent validation.

To evaluate the impact of persistent opioid use (POU) following surgery or trauma on health outcomes using linked data. ⋯ Among opioid-naive patients who received opioids after surgery or trauma, POU was associated with worse outcomes, including increased mortality. Further investigation is warranted to understand the reasons for continued opioid use beyond 90 days and mechanisms associated with harm.

To determine the association between postdischarge mental health care and odds of readmission after emergency general surgery (EGS) hospitalization for patients with serious mental illness (SMI). ⋯ Postdischarge MHV after EGS hospitalization was associated with decreased odds of readmission for patients with SMI managed operatively and nonoperatively. In older EGS patients with SMI, coordination of MHVs may be a mechanism to reduce readmission disparities.

Pediatric intracranial space-occupying lesions are common, with prognoses improving markedly in recent years, significantly extending survival. As such, there is an imperative to pay increased attention to the postoperative cognitive functions and brain network alterations in these children because these factors significantly influence their quality of life. Temporal variability (TV) analysis of brain networks captures the full extent of resting-state activities, reflecting cognitive functions and rehabilitation potential. However, previous research rarely uses TV analyses and most focus on adults or children after multidisciplinary treatments, not reflecting the combined effect caused by neurosurgery only and self-repair. This study gives our insights into this field from a holistic perspective. ⋯ These findings suggest significant intrinsic repair in cognitive functions and brain networks at around 3 months postneurosurgery in children. This study not only enriches our comprehension of postoperative cognitive and brain network self-repair processes in children but also furnishes potential therapeutic targets for rehabilitation interventions and establishes a theoretical foundation for proactive surgical interventions.
