PURPOSE: This study was conducted to identify the factors that influence nurses' organizational citizenship behavior. METHODS: A cross-sectional design was used, with a convenience sample of 547 nurses from four university hospitals in Seoul and Gyeonggi province. The data were collected through a questionnaire survey done from September 22 to October 10, 2008. The tools used for this study were scales on organizational citizenship behavior (14 items), self-leadership (14 items), empowerment (10 items), organizational commitment (7 items), job satisfaction (8 items) and transformational.transactional leadership (14 items). Cronbach's alpha and factor analysis were examined to test reliability and construct validity of the scale. The data collected were processed using SPSS Window 15.0 Program for actual numbers and percentages, differences in the dependent variable according to general characteristics, and means, standard deviations, correlation coefficients and multiple regression analysis. RESULTS: The factors influencing nurses' organizational citizenship behavior were identified as self-leadership (beta=.247), empowerment (beta=.233), job satisfaction (beta=.209), organizational commitment (beta=.158), and transactional leadership (beta=.142). Five factors explained 42.0% of nurses' organizational citizenship behavior. CONCLUSION: The results of this study can be used to develop further management strategies for enhancement of nurses' organizational citizenship behavior.

OBJECTIVES: Obsessive-compulsive disorder (OCD) is a disabling psychiatric disorder, and more attention is recently paid on the quality of life (QoL) in OCD patients. The Euro-QoL-5D (EQ-5D) is a widely used self-report to calculate a single score which represents ‘health utilities’. The aim of this study was to assess the health-related QoL for patients with OCD using the EQ-5D and to examine the relationship between health-related QoL and symptom severity. METHODS: Seventy-three patients with a Diagnostic and Statistical Manual of Mental Disorders (DSM-5) diagnosis of OCD were recruited from the outpatient clinic in Seoul National University Hospital. Symptom severity was assessed using the Yale-Brown Obsessive-Compulsive Scale (YBOCS), and QoL was assessed with the EQ-5D-5L questionnaire. Using Korean valuation study, a single score of QoL was calculated. RESULTS: Most of the OCD patients were relatively young (< 45 years) with the mean YBOCS total score of 19.33. The mean EQ-5D score was 0.71 and significantly correlated with symptom severity (r = -0.483, p < 0.001). 25% of the EQ-5D score was predicted by the YBOCS total score (b = -0.011, p < 0.001) by regression analysis. CONCLUSIONS: OCD patients suffer from lower health-related QoL and QoL significantly decreased as symptom severity increased. The results of the EQ-5D would enable further studies on QoL comparison across medical disease and mental disorders.

We reported on a 60-year-old man presenting lymphedema of both lower extremities and scrotum for 3 years with unknown cause. We took a computed tomography scan of the lower extremities as a follow-up. There were diffuse subcutaneous edema in both lower extremities and multiple enlarged lymph nodes along the para-aortic and bilateral inguinal areas. For further evaluation, biopsy of an enlarged inguinal lymph node was taken, yielding a diagnosis of primary amyloidosis. A treatment of chemotherapy for amyloidosis was recommended for him. To our knowledge, this is the first report of lymphedema presenting with primary amyloidosis in Asia. This case suggests that primary amyloidosis could be one of the differential diagnoses in patients with lymphedema in the lower extremities.

OBJECTIVES: Narcolepsy with cataplexy is a rare chronic sleep disorder characterized by excessive daytime sleepiness, cataplexy, sleep paralysis, and hypnagogic/hypnopompic hallucinations. The aims of the present study were comparing the health-related quality of life (HR-QOL) of patients with type I and type II narcolepy patients, and determining the factors that influence the HR-QOL in narcolepsy patients. METHODS: All patients performed night polysomnography (PSG) and multiple sleep latency test (MSLT). HR-QOL and the severity of subjective symptoms were evaluated using various questionnaires, including the Korean versions of the Medical Outcome Study Short Form-36, the Pittsburg Sleep Quality Index-Korean version, the Korean version Epworth Sleepiness Scale, and the Korean version Beck Depression Inventory-2. RESULTS: We enrolled 21 type I narcolepsy patients and 27 type II patients. Type I patients had short rapid eye movement (REM) latency on night PSG and more sleep onset REM periods on MSLT. The total score of HR-QOL was worse in patients with type I narcolepsy than in the type II narcolepsy patients. There was association between the severities of excessive daytime sleepiness, depression and the degree of worsening of QOL. CSF hypocretin level had no correlation with the scores of HR-QOL. CONCLUSIONS: These findings demonstrate that type I narcolepsy patients are sleepier, depressive, and have more burden on the HR-QOL. And the impairment in QOL of narcolepsy patients is related to the degree of excessive daytime and depressive mood.

OBJECTIVES: Obsessive-compulsive disorder (OCD) is a chronic and disabling psychiatric disorder. The duration of untreated illness (DUI) has been suggested as one of the predictors of clinical course and outcome in various psychiatric disorders. There is increasing evidence that cognitive dysfunction is associated with the prognosis of OCD. The aim of this study was to investigate the influence of DUI on the neurocognitive functions in patients with OCD. METHODS: Sixty-two patients with a DSM-IV diagnosis of OCD from the outpatient clinic were included in this study. We defined the short DUI if the DUI was 2-year or less and the long DUI if it was longer than 2-year. Neurocognitive functions were assessed by visuospatial memory function test and 4 subsets of K-WAIS such as vocabulary, arithmetic, block design and picture arrangement. Differences in neurocognitive functions as well as clinical variables between OCD patients with short DUI and those with long DUI were investigated. Correlation analyses were also performed to determine the correlation between DUI and neurocognitive functions. RESULTS: Compared with the short DUI group, the long DUI group performed worse in the block design test, which measures executive function. The long DUI group also had a higher level of compulsive symptom severity than the short DUI group. However, the DUI was not correlated with neurocognitive functions. CONCLUSIONS: Findings in this preliminary study suggest that the long DUI in patients with OCD is associated with more severe executive dysfunction. Studies with larger samples and longitudinal design are needed to further confirm the prognostic role of the DUI in OCD.

OBJECTIVE: We investigated the differences of functions, activity of daily living (ADL), and quality of life (QoL) according to hand dominance in hemiplegic stroke patients. METHOD: The participants were diagnosed as stroke at P hospital. 370 participants (356 right dominant hand, 14 left dominant hand) were right hemisphere stroke, and 258 participants (248 right dominant hand, 10 left dominant hand) were left hemisphere stroke. To compensate the differences of imbalance in the number of participants' hand dominance, we performed the propensity score matching analysis. We analyzed the variation of stroke severity, disability, motor, mobility, cognition and language functions from 7 days until 3 months after onset using analysis of covariance (ANCOVA). Then, we performed independent t-test to compare hand dexterity, ADL, mood, subjective health condition and QoL of participants according to the hand dominance and the affected hemisphere. RESULTS: All groups showed increased functions during 3 months without statistically significant differences according to hand dominance in both right and left hemisphere stroke patients. In addition, ADL, mood, subjective health condition and QoL were also not significantly different depending on hand dominance in the right and left hemisphere. CONCLUSION: The difference of hand dominance did not influence stroke severity, disability, motor, mobility, cognition or language functions. It also didn't correlate with ADLs, mood or QoL.

Purpose:
This study aimed to assess the technical performance of ElastQ Imaging compared with ElastPQ and to investigate the correlation between liver stiffness (LS) values obtained using these two techniques.
Methods:
This retrospective study included 249 patients who underwent LS measurements using both ElastPQ and ElastQ Imaging equipped on the same machine. The applicability, repeatability (coefficient of variation [CV]), acquisition time, and LS values were compared using the chi-square or Wilcoxon signed-rank tests. In the development group, the correlation between the LS values obtained by the two techniques was assessed with Spearman correlation coefficients and linear regression analysis. In the validation group, the agreement between the estimated and real LS values was evaluated using a Bland-Altman plot.
Results:
ElastQ Imaging had higher applicability (94.0% vs. 78.3%, P<0.001) and higher repeatability, with a lower median CV (0.127 vs. 0.164, P<0.001) than did ElastPQ. The median acquisition time of ElastQ Imaging was significantly shorter than that of ElastPQ (45.5 seconds vs. 96.5 seconds, P<0.001). The median LS value obtained using ElastQ Imaging was significantly higher than that obtained using ElastPQ (5.60 kPa vs. 5.23 kPa, P<0.001). The LS values between the two techniques exhibited a strong positive correlation (r=0.851, P<0.001) in the development group. The mean difference and 95% limits of agreement were 0.0 kPa (-3.9 to 3.9 kPa) in the validation group.
Conclusion
ElastQ Imaging may be more reliable and faster than ElastPQ, with strongly correlated LS measurements.

BACKGROUND/AIMS:
The impact of malnutrition on the outcome of hospitalized adults with community-acquired pneumonia (CAP) has not been fully investigated. This study evaluated the prevalence and prognostic significance of malnutrition in a Korean population with CAP.
METHODS:
In total, 198 patients with CAP from November 2014 to September 2015 were analyzed retrospectively. We assessed the prevalence of malnutrition and the risk factors for 2-year mortality. Furthermore, we divided the patients into two groups: elderly (age ≥ 65 years, n = 131) and non-elderly (age < 65 years, n = 67). Subgroup analyses were performed in the elderly group through propensity score matching.
RESULTS:
The prevalence of malnutrition was 39.4%, and the proportion of patients with malnutrition was significantly higher (53.4% vs. 11.9%, p < 0.001) in the elderly group than in the non-elderly group. In-hospital mortality, 1-year mortality, and 2-year mortality rates were 4.5%, 19.2%, and 26.8%, respectively. Multivariate Cox regression analyses revealed that malnutrition (odds ratio [OR], 2.52; 95% confidence interval [CI], 1.39 to 4.60; p = 0.002) and the Charlson comorbidity index score (OR, 1.30; 95% CI, 1.17 to 1.45; p < 0.001) were associated with 2-year mortality.
CONCLUSIONS
Malnutrition was common and associated with a poor long-term outcome in patients with CAP, particularly the elderly. A routine nutritional assessment at admission is mandatory as a first step for appropriate nutritional therapy.

Hypernatremia is a common electrolyte disorder in children and elderly people and has high short-term mortality. However, no high-quality studies have examined the correction rate of hypernatremia and the amount of fluid required for correction. Therefore, in this study, we will compare the efficacy and safety of rapid intermittent bolus (RIB) and slow continuous infusion (SCI) of electrolyte-free solution in hypernatremia treatment. Methods: This is a prospective, investigator-initiated, multicenter, open-label, randomized controlled study with two experimental groups. A total of 166 participants with severe hypernatremia will be enrolled and divided into two randomized groups; both the RIB and SCI groups will be managed with electrolyte-free water. We plan to infuse the same amount of fluid to both groups, for 1 hour in the RIB group and continuously in the SCI group. The primary outcome is a rapid decrease in serum sodium levels within 24 hours. The secondary outcomes will further compare the efficacy and safety of the two treatment protocols. Conclusion: This is the first randomized controlled trial to evaluate the efficacy and safety of RIB correction compared with SCI in adult patients with severe hypernatremia.
