Purpose: The purpose of this study was to compare the positive outcomes of fixed night shift, such as fatigue recovery experiences, work-life balance, and retention intentions, among nurses who had experienced both rotating shifts and fixed night shift. Methods: A single-cohort pre-post study design was used to compare the fatigue recovery experience, work-life balance, and retention intentions of nurses who have experienced fixed night shift. The study included 59 nurses working at a single university hospital in Seoul from September 1, 2023, to December 31, 2023. Data were analyzed using frequency and percentage, mean and standard deviation, t-test and ANOVA, paired t-test using the R statistical program. Results: The results revealed that acute and chronic fatigue levels decreased among nurses of night shifts during fatigue recovery assessment.However, the inter-shift recovery score did not improve, indicating that nurses' fatigue recovery was insufficient. Work-life balance scores increased, particularly in the area of work-leisure balance. Retention intention also improved among nurses of fixed night shift, but this was not statistically significant. Conclusion Based on the results of this study, the successful establishment of a fixed night shift system will reduce the turnover rate of the next generation of nurses and create a medical environment where nurses can spend more time on direct patient nursing care. Furthermore, we hope to improve the quality of life of nurses and improve the health outcomes of patients.

BACKGROUND AND OBJECTIVES: Pleomorphic adenoma is the most common benign neoplasm of the parotid gland. It is well known that margin involvement, pseudopod and satellite nodule are factors contributing to recurrence. In this study, we investigated the pathologic characteristics in the parotidectomy specimen of the pleomorphic adenoma. SUBJECTS AND METHOD: From January 2002 to July 2007, 45 patients who were diagnosed as pleomorphic adenoma of the parotid gland were selected, and their pathologic slides were reviewed by a pathologist. The narrowest resection margin and capsular characteristics such as incomplete capsule, pseudopod and satellite nodule were checked. Also, the relationship between pathologic subtype and the capsular characteristics was analyzed. RESULTS: The narrowest resection margin was related to size and location of the tumor. Smaller tumor had larger resection margin with stastistical significance and tumor located in the superficial lobe had larger resection margin. In pathologic subtypes, capsular characteristics such as incomplete capsule and satellite nodule were more frequent in myxochondroid type. Even in small tumor (<2 cm), capsular characteristics such as satellite nodule and pseudopod were not infrequent. CONCLUSION: Average resection margin was 4 mm but variable. Because the incidence of satellite nodule, pseudopod and incomplete capsule is about 30% in parotid pleomorphic adenoma, the resection of the tumor containing normal parotid tissue is important to reduce the risk of recurrence.

Background/Aims: High-resolution manometry (HRM) has broadened the awareness of minor esophageal peristaltic disorders. However, the treatments for these minor disorders are limited and the role of prokinetics has been controversial. This study evaluates the effect of mosapride in patients with minor peristaltic disorders. Methods: This study prospectively enrolled 21 patients with esophageal symptoms who were diagnosed with minor peristaltic disorders by gastroscopy and HRM using the Chicago classification version 3.0. Patients received mosapride 30 mg daily for 2 weeks. Symptoms were assessed using the abbreviated World Health Organization quality of life scale (WHOQOL-BREF) and a HRM study was performed before and after 2 weeks of treatment. Results: HRM metrics of lower esophageal sphincter (LES) respiratory mean pressure (median 14.6 mmHg vs 17.3 mmHg; interquartile range [IQR] 8.7-22.5 mmHg vs 12.5-25.9 mmHg; P = 0.004) and distal contractile integral (median 343.8 mmHg·sec·cm vs 698.1 mmHg·sec·cm; IQR 286.5-795.9 mmHg·sec·cm vs 361.0-1127.6 mmHg·sec·cm; P = 0.048) were significantly increased after treatment. Complete response (≥ 80.0%), satisfactory response (≥ 50.0%), partial response (< 50.0%), and refractory response rates were 19.0%, 52.4%, 14.3%, and 14.3%, respectively. However, there was no statistical difference in all WHOQOL-BREF scores before and after treatment. Univariate analysis showed LES respiratory mean pressure (P = 0.036) was associated with symptom improvement (complete + satisfactory group). However, no statistical difference was found in other factors after multivariate analysis. Conclusions Mosapride improved esophageal symptoms and significantly increased LES respiratory mean pressure and distal contractile integral. Therefore, mosapride could enhance LES and esophageal body contraction pressures in patients with minor peristaltic disorders.

OBJECTIVE: Patients with lung cancer have a relative high risk of developing secondary primary lung cancers. This study examined the additional value of autofluorescence bronchoscopy (AFB) for diagnosing synchronous lung cancers and premalignant lesions. METHODS: Patients diagnosed with lung cancer from January 2005 to December 2005 were enrolled in this study. The patients underwent a lung cancer evaluation, which included white light bronchoscopy (WLB), followed by AFB. In addition to the primary lesions, any abnormal or suspicious lesions detected during WLB and AFB were biopsied. RESULTS: Seventy-six patients had non-small cell lung cancer (NSCLC) and 23 had small cell lung cancer (SCLC). In addition to the primary lesions, 84 endobronchial biopsies were performed in 46 patients. Five definite synchronous cancerous lesions were detected in three patients with initial unresectable NSCLC and in one with SCLC. The secondary malignant lesions found in two patients were considered metastatic because of the presence of mediastinal nodes or systemic involvement. One patient with an unresectable NSCLC, two with a resectable NSCLC, and one with SCLC had severe dysplasia. The detection rate for cancerous lesions by the clinician was 6.0% (6/99) including AFB compared with 3.0% (3/99) with WLB alone. The prevalence of definite synchronized cancer was 4.0% (4/99) after using AFB compared with 2.0% (2/99) before, and the staging-up effect was 1.0% (1/99) after AFB. Since the majority of patients were diagnosed with advanced disease, the subjects with newly detected cancerous lesions did not have their treatment plans altered, except for one patient with a stage-up IV NSCLC who did not undergo radiotherapy. CONCLUSIONS: Additional AFB is effective in detecting early secondary cancerous lesions and is a more precise tool in the staging workup of patients with primary lung cancer than with WLB alone.
