Objective: This study aimed to investigate the different clinical characteristics among elderly coronavirus disease 2019 (COVID-19) patients with and without mental disorders in South Korea and determine if these characteristics have an association with underlying mental disorders causing mortality., Method: A population-based comparative cohort study was conducted using the national claims database. Individuals aged ≥65 years with confirmed COVID-19 between January 1, 2020 and April 10, 2020 were assessed. The endpoints for evaluating mortality for all participants were death, 21 days after diagnosis, or April 10, 2020. The risk of mortality associated with mental disorders was estimated using Cox hazards regression., Results: We identified 814 elderly COVID-19 patients (255 [31.3%] with mental disorder and 559 [68.7%] with nonmental disorder). Individuals with mental disorders were found more likely to be older, taking antithrombotic agents, and had diabetes, hypertension, chronic obstructive lung disease, and urinary tract infections than those without mental disorders. After propensity score stratification, our study included 781 patients in each group (236 [30.2%] with mental disorder and 545 [69.8%] with nonmental disorder). The mental disorder group showed higher mortality rates than the nonmental disorder group (12.7% [30/236] versus 6.8% [37/545]). However, compared to patients without mental disorders, the hazard ratio (HR) for mortality in elderly COVID-19 patients with mental disorders was not statistically significant (HR: 1.57, 95%CI: 0.95-2.56)., Conclusion: Although the association between mental disorders in elderly individuals and mortality in COVID-19 is unclear, this study suggests that elderly patients with comorbid conditions and those taking psychiatric medications might be at a higher risk of COVID-19., (Copyright © 2020 American Association for Geriatric Psychiatry.

Conclusion: (18)F-FDG PET/CT is a useful technique for the evaluation of paraglottic space invasion and lymph node metastasis in patients with supracricoid partial laryngectomy (SCPL). Primary SUVmax values (using 7.0 as a cut-off) and nodal SUVmax values (using 2.2 as a cut-off) are important for recurrence and poor prognosis., Objectives: The purpose of this study was to evaluate the usefulness of (18)F-FDG PET/CT for paraglottic space invasion and lymph node metastasis and the prognostic significance in SCPL., Methods: The medical records of 42 patients who underwent (18)F-FDG PET/CT for SCPL before surgery were reviewed., Results: The median primary SUVmax was 6.63 ± 5.07 and the median nodal SUVmax was 1.25 ± 1.86. The primary SUVmax values with paraglottic space invasion (8.34 ± 5.92) and without (4.57 ± 2.74) were significantly different (p = 0.015). The (18)F-FDG PET/CT had an accuracy of 87% for the identification of cervical metastases on a level-by-level basis. A median primary SUVmax value of 7.0 and nodal SUVmax of 2.2 were associated with recurrence (p = 0.022 and p = 0.009, respectively) and 5-year disease-specific survival (p = 0.021 and p = 0.041, respectively).

Conclusion: Factors that affected prognosis were T stage and extracapsular spread in patients that underwent primary surgery with postoperative radiotherapy for pN2 head and neck carcinoma., Objectives: The purpose of this study was to examine treatment outcomes and define prognostic factors for pN2 head and neck carcinoma., Methods: A total of 209 patients underwent surgery with postoperative radiotherapy between 1994 and 2011. Primary tumor sites were the oropharynx (n = 70), hypopharynx (n = 48), larynx (n = 47), and oral cavity (n = 44). There were 21, 83, 60, and 45 patients with stage T1 to T4 cancers, respectively. The N stages were 20 N2a, 129 N2b, and 60 N2c., Results: The recurrence rate was 40% (83/209) over a mean observation period of 39 months. The 5-year disease-free survival (DFS), disease-specific survival (DSS), and overall survival (OS) rates in our cohort were 44%, 60%, and 56%, respectively. The presence of advanced T stage or extracapsular spread had a significant adverse effect on 5-year DFS, DSS, and OS rates according to Kaplan-Meier survival curves. Multivariate Cox regression analysis confirmed the significant association between 5-year DSS rate and advanced T stage (hazard ratio (HR), 2.20; 95% confidence interval (CI), 1.26-3.82; p = 0.005) and extracapsular spread (HR, 2.29; 95% CI, 1.24-4.21; p = 0.008).
