Background:
We examined the effect of psychiatric comorbidities on perioperative surgical outcomes and the leading causes of readmissions in patients who underwent thyroid and parathyroid operations.
Method:
Patient information was retrieved from the Nationwide Readmission Database (2010-2017). Multivariate analysis was used to identify predictors for hospital readmissions.
Results:
A total of 181,007 and 53,808 patients underwent thyroid and parathyroid operations, respectively. Of those, 8,468 (4.7%) and 6,112 (11.4%) patients were readmitted within 30 days. Psychiatric comorbidities were more frequent in readmitted cohorts after thyroidectomies (14.9% vs 10.4%; P < .001) and parathyroidectomies (16.8% vs 11.5%; P < .001), with anxiety being the most frequent cause (thyroid: 7.87%, parathyroid: 6.8%). Psychiatric comorbidities were associated with greater risk of in-hospital mortality (thyroid: odds ratio = 2.07, 95% confidence interval = 1.13-3.53; P = .015 and parathyroid: odds ratio = 1.67, 95% confidence interval = 1.04-2.70; P = .005), postoperative complications (thyroid: odds ratio = 1.528, 95% confidence interval = 1.473-1.585; P < .001 and parathyroid: odds ratio = 3.26, 95% confidence interval = 2.84-3.73; P < .001), prolonged duration of stay (thyroid: beta coefficient = 1.142, 95% confidence interval = 1.076-1.207; P < .001 and parathyroid: beta coefficient = 2.15, 95% confidence interval = 1.976-2.32; P < .001), and 30-day readmissions (thyroid: hazard ratio = 1.18, 95% confidence interval = 1.03-1.18; P = .047 and parathyroid: hazard ratio = 1.23, 95% confidence interval = 1.11-1.36; P < .001). Psychosis had the greatest risk of readmission (thyroid: hazard ratio = 1.51 and parathyroid: hazard ratio = 1.42), and dementia (odds ratio = 2.58) had the greatest risk of postoperative complications.
Conclusion:
Concomitant psychiatric conditions after thyroid and parathyroid operations were associated with increased risk of postoperative complications, prolonged hospital stays, and greater rates of readmissions.

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
