Anesthesia, Anesthetics, and Postoperative Cognitive Dysfunction in Elderly Patients.

Postoperative cognitive dysfunction (POCD) remains a major issue that worsens the prognosis of elderly surgery patients. This article reviews the current research on the effect of different anesthesia methods and commonly utilized anesthetics on the incidence of POCD in elderly patients, aiming to provide an understanding of the underlying mechanisms contributing to this condition and facilitate the development of more reasonable anesthesia protocols, ultimately reducing the incidence of POCD in elderly surgery patients.

Long-Term Outcomes and Factors Related to the Prognosis of Pure Ovarian Dysgerminoma: A Retrospective Study of 107 Cases.

OBJECTIVE: The aim of this study was to evaluate the long-term outcomes and the factors related to patient prognosis. MATERIALS AND METHODS: We retrospectively analyzed patients treated at the Department of Gynecology, Sun Yat-sen University Cancer Center, between January 1, 1968, and December 12, 2018. RESULTS: A total of 107 patients were identified. Of all patients, 79 (73.8%) presented with stage I disease, 14 (13.1%) stage II, 13 (12.2%) stage III, and 1 (0.9%) stage IV. All patients received surgery, with 70 (65.4%) undergoing fertility-sparing surgery (FS) and 37 (34.6%) nonfertility-sparing surgery (NFS). Ninety patients received postoperative chemotherapy. Nine of the 43 cases with a lymphadenectomy had metastasis (20.9%). The median follow-up time was 132 months (range, 1-536 months). The overall 5-year and 10-year survival was 95.1% and 91.7%, respectively. The 10-year survival rate for stage I and II-IV patients was 96.1% and 79.1%, respectively (p = 0.008). For the patients undergoing FS and NFS, the 10-year disease-free survival rate was 82.3% and 88.0%, respectively (p = 0.403). The 10-year disease-free survival rate for patients with or without lymphadenectomy was 95.1% and 78.4%, respectively (p = 0.040), and it was 92.5% and 76.0%, respectively (p = 0.041), for those with or without omentectomy. Fifteen patients relapsed, and 4 of them (26.7%) had recurrence in the lymph nodes. Eleven of the 15 relapsed patients (73.3%) had been successfully salvaged. LIMITATIONS: As a study of a rare disease, our analysis was limited by its small sample size and the deemed disadvantage of a retrospective study. CONCLUSION: Excellent treatment results can be achieved in dysgerminoma patients who received proper treatment. Lymphadenectomy may improve patient survival. Relapsed patients can also be successfully salvaged.
