PURPOSE: This descriptive study investigated the effects of authentic leadership and coworker support on psychological well-being of staff nurses. METHODS: The participants were 166 staff nurse working in university hospital located in D city. Data were collected from July 1 2017 to 31, 2017. Data analysis was performed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and hierarchical regression. RESULTS: The regression model that included demographics and coworker support explained about 40.0% of psychological well-being. Marital status, nurse satisfaction, turnover experience, and coworker support were the predictors of psychological well-being in staff nurses. CONCLUSION: Coworker support was an important predictor of the psychological well-being of staff nurse. Therefore, strategics to improve coworker support are needed to increase psychological well-being in the clinical field.

Spontaneous intracranial hypotension (SIH) is characterized by orthostatic headache, diffuse dural thickening, and enhancement in magnetic resonance imaging. Cerebral venous thrombosis (CVT) has been reported to be a rare complication of SIH. There is no consensus in anticoagulation treatment of CVT secondarily caused by SIH. We report a female patient with SIH complicated by CVT and spontaneously regressed CVT not by anticoagulation but by epidural blood patch.

BACKGROUND AND PURPOSE: Two conversion scales between the Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA) have been validated for Korean patients with Parkinson's disease. The aim of the present study was to validate these conversion scales for all patients with cognitive impairments regardless of dementia subtype. METHODS: Medical records of 323 subjects who completed both MMSE and MoCA on the same day were retrospectively reviewed. Mean, median, and root mean squared error (RMSE) of the difference between true and equivalent MMSE scores were calculated. Intraclass correlation coefficients (ICCs) between true and equivalent MMSE scores were also calculated. The validity of MoCA-MMSE conversion scales was evaluated according to educational level (low educated: ≤6 years; high educated: ≥7 years) and subtypes of cognitive impairment. RESULTS: The difference between true and equivalent MMSE scores had a median value of 0, a mean value of 0.19 according to the van Steenoven scale, a mean value of 0.57 according to the Lawton scale, RMSE value of 2.2 according to the van Steenoven scale, and RMSE value of 0.42 according to the Lawton scale. Additionally, ICCs between true and equivalent MMSE scores were 0.92 and 0.90 on van Steenovan and Lawton conversion scales, respectively. These results were maintained in subgroup analyses. CONCLUSIONS: Findings of the present study suggest that both van Steenovan and Lawton MoCA-MMSE conversion scales are applicable to transforming MoCA scores into MMSE scores in patients with cognitive impairments regardless of dementia subtype or educational level.

BACKGROUND: STDs are major communicable disease group in Korea. This study was carried out to evaluate the current status of sexually transmitted diseases in Seoul. METHODS: We collected the laboratory data of those who visited 11 Public Health Centers in Seoul for venereal disease examination and analyzed abnormal results from Jan 1, 1993 to Dec 31, 1995. The diagnoses of STDs were made by VDRL quantification, TPHA test, Gram's stain, and culture of urine or urethral discharge. RESULTS: There were total of 10,302 patients. There were 7,836 male cases(76.1%) and 2,466 female cases (23.9%). Mean age was 30.6+/-9.7, and the most common age group was 25-34 yearn of age(42.1%). Diagnoses were as follows ; syphilis 2,036 cases(19.8%), gonorrhea 2,249 cases(21.8%), nongonococcal urethritis 4,973 cases(48.3%), vaginitis 954 cases(9.3%), mixed infection of syphilis and gonorrhea 13 cases(0.1% ), mixed infection of syphilis and NGU 50 cases(0.5%), mixed infection of syphilis and vaginitis 27 cases(0.3%). The proportion of PPNG among gonorrhea was as follows ; 43.4% in 1993, 55.1% in 1994, 43.8% in 1995. There were more WBCs on Gram's staining in gonorrhea cases than in NGU cases. CONCLUSIONS: The STD patients seen in 11 Public Health Centers in Seoul were mainly young men. Common diagnoses were as follows ; NGU, gonorrhea, syphilis, vaginitis. The proportion of PPNG increased at first and then decreased.

BACKGROUND/AIMS: Colorectal cancer (CRC) screening using stool DNA was recently found to yield good detection rates. A multi-target stool DNA test (Cologuard®, Exact Sciences), including methylated genes has been recently approved by the U.S. Food and Drug Administration. The aim of this study was to validate these aberrantly methylated genes as stool-based DNA markers for detecting CRC and colorectal advanced adenoma (AA) in the Korean population. METHODS: A single-center study was conducted in 36 patients with AA; 35 patients with CRC; and 40 endoscopically diagnosed healthy controls using CRC screening colonoscopy. The methylation status of the SFRP2, TFPI2, NDRG4, and BMP3 promoters was investigated blindly using bisulfate-modified stool DNA obtained from 111 participants. Methylation status was investigated by methylation-specific polymerase chain reaction. RESULTS: Methylated SFRP2, TFPI2, NDRG4, and BMP3 promoters were detected in 60.0%, 31.4%, 68.8%, and 40.0% of CRC samples and in 27.8%, 27.8%, 27.8%, and 33.3% of AA samples, respectively. The sensitivities obtained using 4 markers to detect CRC and AA were 94.3% and 72.2%, respectively. The specificity was 55.0%. CONCLUSIONS: Our results demonstrate that the SFRP2, TFPI2, NDRG4, and BMP3 promoter methylation analysis of stool sample DNA showed high sensitivity but low specificity for detecting CRC and AA. Because of the low specificity, 4 methylated markers might not be sufficient for CRC screening in the Korean population. Further large-scale studies are required to validate the methylation of these markers in the Asian population and to find new markers for the Asian population.

Chronic traumatic encephalopathy (CTE) is a progressive neurodegenerative disorder that is associated with repetitive head injury and has distinctive neuropathological features that differentiate this disease from other neurodegenerative diseases. Intraneuronal tau aggregates, although they occur in different patterns, are diagnostic neuropathological features of CTE, but the precise mechanism of tauopathy is not known in CTE. We performed whole RNA sequencing analysis of post-mortem brain tissue from patients with CTE and compared the results to normal controls to determine the transcriptome signature changes associated with CTE. The results showed that the genes related to the MAP kinase and calcium-signaling pathways were significantly downregulated in CTE. The altered expression of protein phosphatases (PPs) in these networks further suggested that the tauopathy observed in CTE involves common pathological mechanisms similar to Alzheimer's disease (AD). Using cell lines and animal models, we also showed that reduced PPP3CA/PP2B phosphatase activity is directly associated with increases in phosphorylated (p)-tau proteins. These findings provide important insights into PP-dependent neurodegeneration and may lead to novel therapeutic approaches to reduce the tauopathy associated with CTE.
