Background: This study compared hearing outcomes with use of personal sound amplification products (PSAPs) and hearing aids (HAs) in patients with moderate to moderately severe unilateral hearing loss. Methods: Thirty-nine participants were prospectively enrolled, and randomly assigned to use either one HA (basic or premium type) or one PSAP (basic or high-end type) for the first 8 weeks and then the other device for the following 8 weeks. Participants underwent a battery of examinations at three visits, including sound-field audiometry, word recognition score (WRS), speech perception in quiet and in noise, real-ear measurement, and self-report questionnaires. Results: Functional gain was significantly higher with HAs across all frequencies (P < 0.001). While both PSAPs and HAs improved WRS from the unaided condition, HAs were superior to PSAPs. The speech recognition threshold in quiet conditions and signal-to-noise ratio in noisy conditions were significantly lower in the HA-aided condition than in the PSAP-aided condition, and in the PSAP-aided condition than in the unaided condition. Subjective satisfaction also favored HAs than PSAPs in questionnaires, Abbreviated Profile of Hearing Aid Benefit, International Outcome Inventory for Hearing Aids, and Host Institutional Questionnaire. Conclusion While PSAPs provide some benefit for moderate to moderately severe unilateral hearing loss, HAs are more effective. This underscores the potential role of PSAPs as an accessible, affordable first-line intervention in hearing rehabilitation, particularly for individuals facing challenges in accessing conventional HAs.

Purpose: Women are more vulnerable to post-traumatic stress (PTS) than men, causing several health problems. Nurses should understand and work with women who have experienced trauma and provide interventions to promote their physical, social, and mental health. Methods: This quasi-experimental pilot study used a one-group pre-test/post-test design. Data were collected from 14 women recruited between December 2019 and May 2020 from a self-sufficiency support center in South Korea for sexually-exploited women who had experienced trauma. The program consisted of six one-on-one intervention sessions per week for six weeks. Each session averaged 60~120 minutes. Participants were assessed at pre-test, post-test, and one-month follow-up. Changes in outcome variables over time were analyzed using the Wilcoxon signed-rank and Friedman tests. Results: The caring program for health promotion was divided into six sessions: understanding the self, sharing traumatic events and negative emotions, reframing the meaning of traumatic events, identifying thoughts and physical and emotional responses, developing health promotion activities, and maintaining a positive attitude during the process of change. As a result of the caring program, PTS (F = 36.33, p < .001), depression (F = 24.45, p < .001), health-promoting behaviors (F = 7.06, p = .004), and self-esteem (F = 19.74, p < .001) among the participants differed significantly at pre-test, post-test, and follow-up. Conclusion This study provides foundational information for the implementation of a theory-driven program by nurses in clinical and community settings to provide comprehensive care for women who have experienced trauma.

Background and Objectives: The quality of life after thyroidectomy, such as voice change, is considered to be as important as control of the disease. In this study, we aimed to evaluate changes in both subjective and objective voice parameters after thyroidectomy resulting in normal morbidity of the vocal cords.Materials and Method In this prospective cohort study, 204 patients who underwent thyroidectomy with or without central neck dissection at a single referral center from Feb 2015 to Aug 2016 were enrolled. All patients underwent prospective voice evaluations including both subjective and objective assessments preoperatively and then at 2 weeks, 3, 6, and 12 months postoperatively. Temporal changes of the voice parameters were analyzed. Results: Values of the subjective assessment tool worsened during the early postoperative follow-up period and did not recover to the preoperative values at 12 months postoperatively. The maximal phonation time gradually decreased, whereas most objective parameters, including maximal vocal pitch (MVP), reached preoperative values at 3–6 months postoperatively. The initial decrease in MVP was significantly greater in patients undergoing total thyroidectomy, and their MVP recovery time was faster than that of patients undergoing lobectomy (p=0.001). Patients whose external branch of the superior laryngeal nerve was confirmed intact by electroidentification showed no difference in recovery speed compared with patients without electroindentification (p=0.102), although the initial decrease in MVP was lower with electroidentification. Conclusion Subjective assessment in voice quality and maximal phonation time after thyroidectomy did not show recovery to preoperative values. Aggravation of MVP was associated with surgical extent and electroidentification.

OBJECTIVES: Self-rated health is an instrumental variable to assess the overall health status of a population. However, it remains questionable whether it is still useful for cognitively impaired individuals. Therefore, this study aims to analyze whether self-rated health by the cognitively impaired predicts mortality reliably. METHODS: This study used 7,881 community-dwelling individuals, aged 45 and above, from the Korean Longitudinal Study of Aging (2006-2016). It used the Cox proportional hazard models for analysis. Cognitive status was classified based on the Korean Mini Mental State Examination score and a stratified analysis was used to determine whether the predictability of self-rated health varies according to cognitive status. RESULTS: For cognitively intact individuals, the adjusted hazard ratios (aHR) of mortality were 2.00 (95% confidence interval [CI], 1.18 to 3.41, model 4) for those with ‘bad’ self-rated health and 2.40 (95% CI, 1.35 to 4.25, model 4) for those with ‘very bad’ self-rated heath, respectively, compared with those with ‘very good’ health. The results remain statistically significant even after adjusting for socio-demographic factors, health status, and health-related behaviors. For cognitively impaired individuals, the aHR of mortality was statistically significant for those with ‘very bad’ self-rated health, compared with those with ‘very good’ health, when socio-demographic factors were accounted for (aHR, 3.03; 95% CI, 1.11 to 8.28, model 2). CONCLUSIONS Self-rated health by cognitively impaired individuals remains useful in predicting mortality. It appears to be a valid and reliable health indicator for the rising population with cognitive impairment, especially caused by aging population.

Purpose: The occurrence of trauma-related delirium following postoperative abdominal surgery is associated with a poor prognosis. The purpose of this study was to identify predictive risk factors for trauma-related delirium. Methods: Trauma patient data from a regional trauma center were retrospectively collected from August 2015 to December 2016. The primary inclusion criteria were patients diagnosed with traumarelated delirium following abdominal trauma surgery. Head trauma patients and those under 18 years of age were excluded from this study. A multivariate logistic regression analysis was performed to identify the risk factors associated with trauma-related delirium. Results: Of the 255 trauma patients who met the inclusion criteria, 32 (12.5%) were diagnosed with delirium. The mean values for the age of the patients, Injury Severity Score, Glasgow Coma Scale score, and length of intensive care unit stay were 52.1 ± 17.8 years, 16.9, 14, and 7.1 days, respectively. Among the measured parameters, age [odds ratio (OR), 1.03; 95% confidence interval (CI), 1.01-1.06; p = 0.022)], sex (OR, 0.125; 0.03-0.55; p = 0.006), hemoglobin level (OR, 0.875; CI, 0.68-0.98; p = 0.03), length of stay in the intensive care unit (OR, 1.12; CI, 1.03-1.22; p = 0.01), and having an abdominal operation (OR, 2.92; CI, 1.10-7.23; p = 0.011) showed strong correlations with trauma-related delirium. Conclusion This study showed that abdominal surgery was strongly associated with delirium in patients with traumatic abdominal injury. Thus, changes in consciousness should be carefully monitored following surgery.

BACKGROUND AND OBJECTIVES: Obstructive sleep apnea (OSA) is highly prevalent in commercial vehicle operators (CMVOs). This study aimed to evaluate the poor sleep quality, daytime sleepiness, and the prevalence of self-reported OSA in CMVOs.SUBJECTS AND METHOD: We performed a retrospective review of the medical records of patients who visited a single institution with sleep problems from 2011 January to 2016 December. Among the patients, a total of 38 CMVOs was analyzed. Clinical information, questionnaires about sleep quality (Pittsburg sleep questionnaire, PSQI), excessive daytime sleepiness (Epworth sleepiness scale, ESS) and risk factors for OSA (STOP-Bang) were analyzed. The frequency of motor vehicle accidents and near accidents was assessed, and polysomnography (PSG) was used for OSA diagnosis purposes. RESULTS: The mean age of the study population was 45.3±11.8 years. The average score of PSQI, ESS, and STOP-Bang were 6.75±4.22, 10.79±7.12, and 4.62±3.34, respectively. A significant association between near accidents and high-risk group of OSA was observed [odds ratio (OR)=2.73, 95% confidence interval (CI)=1.08–4.48]. Subjects with poor sleep quality showed significantly increased risk of near accidents (OR=2.34, 95% CI=1.01–3.56). Receiver operating characteristic curves of STOP-Bang questionnaire using apnea-hypopnea index (cut-off value=5) indicates that suspected OSA group predicted by STOP-Bang score was significantly correlated with OSA severity (area under curve=0.72, sensitivity 77.1%, specificity 59.4%). CONCLUSION Administration of STOP-Bang questionnaire before a PSG can identify high-risk subjects, supporting its further use in OSA screening of CMVOs.
