Abstract Context Patients with endogenous hypercortisolism experience glucocorticoid withdrawal syndrome (GWS) after surgery. Meditation may be an effective intervention to alleviate the severity of GWS. Objective To determine the acceptability of a portable, wearable electroencephalography device for guided meditation (MUSE headband) and the impact of MUSE use on GWS and quality of life 12 weeks postsurgery. Methods We conducted a single-center prospective cohort study of adults with endogenous hypercortisolism undergoing curative surgery from 2019 to 2024. Patients had baseline and postsurgical assessments over 12 weeks. The study comprised patients using MUSE for ≥ 6 weeks (MUSE cohort) and patients matched by age, sex, BMI, hypercortisolism type, and glucocorticoid type at 1:4 ratio. Quality of life and GWS symptoms were assessed with AddiQoL, CushingQoL, and 36-item Short Form Health Survey mental and physical component (SF-36 MCS and PCS) questionnaires. Results MUSE was offered to 52 patients, and 22 (42%) used MUSE for ≥ 6 weeks within 12 weeks after surgery. At baseline, compared to 88 matched subjects, 22 MUSE participants demonstrated similar prevalence of comorbidities and clinical and biochemical hypercortisolism severity, but lower AddiQoL (mean 73 vs 66, P = .031) and SF-36 MCS (mean 39 vs 33, P = .022). At 12 weeks, these differences in quality of life were no longer present. After adjusting for age, sex, BMI, clinical severity score, and baseline quality of life, MUSE use was an independent predictor of improved SF-36 PCS at 12 weeks postsurgery (beta 4.2, 95% CI: 0.5-7.9, P = .026). Conclusion Postsurgical meditation intervention may improve physical symptoms and accelerate recovery.

Abstract Context Data on giant pheochromocytomas (PHEOs), defined based on size 10 cm or greater, are scarce. Objective This work aimed to compare presentation, management, and outcomes of patients with giant vs non–giant PHEOs. Methods A retrospective cohort study was conducted in a referral center from 2000 to 2023. Consecutive patients with giant PHEOs and randomly chosen patients with non–giant PHEO (referents) were studied at a 1:6 ratio. Outcomes included perioperative complications, metastases, and mortality. Results Of 828 patients with PHEOs, 31 (3.7%) had giant PHEO (median size 12 cm, interquartile range [IQR] 10.0-13.5 cm). In comparison to referents (n = 186, median size 4 cm, IQR, 2.9-5.0 cm), patients with giant PHEO had more symptoms of catecholamine excess (median of 2 vs 1; P = .04) and presented with a higher prevalence of severe catecholamine excess (76% vs 30%; P < .0001). Adrenalectomy was performed in 94% of patients with giant PHEOs and 100% of referents. In addition to preoperative α-adrenergic blockade (89%), metyrosine was used in 14 (7%) patients, mostly in patients with giant PHEOs (26% vs 3%; P < .0001). Patients with giant PHEOs had a higher perioperative complication rate (31% vs 10%; P = .004). During a median follow-up of 3 years, metastases developed at a higher rate in patients with giant PHEOs (45% vs 4% in referents; P < .0001). Disease-specific mortality was 7% in patients with giant PHEOs and 0% in referents (P = .02). Conclusion Patients with giant PHEOs compared to referents were more symptomatic, had a higher degree of catecholamine excess, and had a higher rate of perioperative complications. Almost half of patients with giant PHEOs developed metastases, warranting close follow-up.
