Purpose: The purpose of this study was to provide basic data to understand the organizational culture of nurses by categorizing nurses' experience of coping with bullying in the workplace through Q methodology and analyzing the characteristics of each type, and to induce correct policy measures and interventions to create an atmosphere created in the nursing clinical field to be more advanced and positive. Methods: To form the Q population, focus group interviews were conducted with nurses working for more than six months at two general hospitals in Seoul and Gyeonggi. Interviews were conducted by 12 nurses introduced to participants who can provide researchers with a wealth of information on workplace bullying experiences without filtration. In addition, the Q population was extracted by reviewing the results. Based on the results derived from this, 38 Q statements in total were extracted. Forty clinical nurses were required to classify Q sample statements, and the data collected through this were analyzed using the pc-QUANAL program. Results: As a result of the analysis, a total of five types of clinical nurses' experiences of coping with bullying in the workplace were identified: ‘tense emotion-based tolerance response,’ ‘positive thinking-based self-effort response’, ‘individualistic thinking-based passive response’, ‘support system-based emotional expression response’ and ‘active response centered on problem-solving’. Conclusion The derived response types are expected to be guidelines for suggesting strategies to eradicate bullying in the workplace at the organizational level, individual level, prevention level, and organizational culture level.

OBJECTIVE: This study evaluated the outcomes of ischemic stroke patients according to delirium motor subtype.METHODS: This study included patients who were admitted to the stroke unit between August 2017 and March 2019 and met the DSM-5 diagnostic criteria for delirium. Patients were assessed twice weekly throughout their delirium episodes using the Korean version of the Delirium Motor Subtype Scale (K-DMSS) and the Korean version of the Delirium Rating Scale-Revised-98 (K-DRS-98). The clinical characteristics and short-term outcomes of the patients were also assessed.RESULTS: A total of 943 stroke patients were included; the rate of incident delirium was 10.18%. Of the 95 delirium patients, 34 were classified as the hyperactive subtype, 30 as the mixed subtype, 25 as the hypoactive and six as no subtype. Among the subtype groups, the hypoactive subtype had the highest initial scores on the National Institutes of Health Stroke Scale (NIHSS; 6.72±4.75, p=0.02) and the modified Rankin Scale (mRS; 3.96±1.24, p<0.01). Additionally, the mixed and hypoactive subtypes had longer durations (p<0.01) and more severe symptoms of delirium (p=0.03) than the other motor subtypes, and the hypoactive subtype group had a significantly longer hospital stay (36.88±27.71 days, p<0.01) than the other subtype groups. After adjusting for baseline covariates in a multiple linear regression analysis, these differences remained significant.CONCLUSION: The present results suggest that the motor subtype of delirium is associated with different characteristics and outcomes in ischemic stroke patients.

BACKGROUND AND OBJECTIVES: Neurologic intolerance (NI) is defined as the occurrence of neurological symptoms during carotid artery stenting (CAS). Because NI is inevitable problem, it may be helpful to anticipate its occurrence. So, we studied factors associated with NI during proximal protected CAS. METHODS: We retrospectively analyzed all consecutive patients underwent proximal protected CAS from August 2012 to January 2017. RESULTS: We included total 123 patients (109 males, 72±8 years old). The total procedure time was 43±12 minutes, and mean occlusion time was 4.8±1.2 minutes. We divided CAS patients into 2 groups according to presence of NI; neurologic tolerance (NT; n=74, 60%) and NI (n=49, 40%) groups. After the univariate analysis, symptomatic carotid artery stenosis (p = 0.003), absence of anterior communicating artery (p = 0.015) and low common carotid artery occlusion pressure (CCAOP, p < 0.001) were associated with NI. After the multivariate analysis, NI was significantly associated with symptomatic carotid artery stenosis (odds ratio [OR], 5.549; p = 0.014) and systolic CCAOP≤42 mmHg (OR, 6.461; p < 0.001). In NI group, 43 patients (88%) recovered right after the balloon deflation and 2 patients were normalized within 2 hours. However, 1 had major stroke and 3 had minor strokes in 4 patients with persistent NI ≥24 hours. CONCLUSIONS: About 40% showed NI during the CAS. Most of them (88%, 43 of 49 patients) recovered after the balloon deflation, but stroke incidence was significantly higher in NI group. Symptomatic carotid artery stenosis and systolic CCAOP ≤42 mmHg were significantly associated with the development of NI during proximal protected CAS.

BACKGROUND: Stroke is the number one cause of adulthood disability in Korea. Rehabilitation after stroke can minimize functional disability, enhance recovery toward independence, and optimize community reintegration. The inter-departmental stroke meeting (IDSM) is a potential method to improve rehabilitation outcomes in patients with stroke. We aimed to analyze the effect of IDSM on rehabilitation after acute ischemic stroke management. METHODS: Medical records of 753 patients with acute ischemic stroke admitted to the neurology department of our medical center between January and December 2014 were reviewed retrospectively. In May 2014, weekly IDSMs were initiated. All physicians responsible for the patient's care reviewed patient treatment, methods of secondary prevention, and future rehabilitation plans. RESULTS: The transfer rate significantly increased after initiation of IDSM (phase 2, 3) and the length of stay (LOS) before transfer to the rehabilitation department decreased significantly from 9.68 ± 8.50 days to 5.75 ± 2.12 days. There was a reduction in the total LOS from 52 ± 28.57 days to 35 ± 27.21 days after IDSMs were introduced. In non-transferred patients also, the total LOS reduced significantly. The transfer rate increased significantly and the LOS before transfer to the rehabilitation department decreased significantly after implementation of IDSM in a subgroup of patients with moderate to severe stroke. CONCLUSION: The introduction of IDSM was significantly correlated with improvements in transfer rates and reduction of LOS in hospital. This finding shows that IDSMs are an important intervention to improve therapeutic progress and outcomes for patients with stroke.

BACKGROUND AND PURPOSE: Rapid recanalization might improve clinical outcomes after intraarterial thrombolysis (IAT) for acute ischemic stroke patients with collateral circulation. We determined whether rapid recanalization and collateral circulation affect clinical outcomes after IAT. METHODS: We retrospectively evaluated the clinical and radiological data of 134 consecutive patients who underwent IAT for intracranial artery occlusion. The interval from symptom onset to recanalization after IAT (onset-to-recanalization time) as an estimate of the probability of good clinical outcome (modified Rankin scale 0-2) was calculated in patients with collateral circulation in the ischemic hemisphere, which was rated poor (0/1 American Society of Interventional and Therapeutic Neuroradiology criteria) or good (2-4). Changes in National Institute of Health Stroke Scale (NHISS) score before and after IAT and modified Rankins scale scores 3 months after discharge were compared with respect to onset-to-recanalization time. RESULTS: In patients with good collateral circulation, the estimated onset-to-recanalization time for a 0.5 probability of a good clinical outcome was 347 minutes; with poor collateral circulation, it was 172 minutes for a 0.2 probability of good clinical outcome. Outcome analyses according to onset-to-recanalization time showed patients recanalized <6 hours had lower NHISS scores (<4.5, 4.5-6, >6 hours of onset-to-recanalization time, and non-recanalization: 5.1, 6.9, 11.9, and 19.8, respectively) at discharge and higher percentages of good clinical outcome (69%, 66.7%, 21.9%, and 0%, respectively) 3 months after IAT. CONCLUSIONS: The time window to expect a high probability of a good clinical outcome after IAT is highly dependent on the collateral circulation.

BACKGROUND AND PURPOSE: We evaluated whether stent-assisted thrombectomy (SAT) is safer or more clinically beneficial than aggressive mechanical clot disruption (AMCD) for patients with acute intracranial artery occlusion. METHODS: We retrospectively analyzed the clinical data of 72 patients (33 with SAT and 39 with AMCD) who underwent intra-arterial thrombolysis for acute intracranial artery occlusions. Procedure parameters, clinical outcomes, and incidence of complications were compared between the SAT and AMCD groups. RESULTS: The time interval to recanalization was shorter in SAT patients (69.2+/-39.6 minutes, mean+/-standard deviation) than in AMCD patients (94.4+/-48.0 minutes, p<0.05). Recanalization was achieved in more SAT patients (91%) than AMCD patients (80%), but with no statistically significance. Urokinase was used less frequently in SAT patients (21%) than in AMCD patients (92%, p<0.05), and the incidence of symptomatic hemorrhages was lower in SAT patients (3%) than in AMCD patients (18%, p<0.05). Device-related complications in SAT patients comprised two cases of stent fracture and one case of distal migration of a captured thrombus. The proportion of patients with good outcomes, defined as scores from 0 to 3 on the modified Rankin Scale, was similar in the two groups at discharge (SAT, 46%; AMCD, 39%), but significantly higher in the SAT group than in the AMCD group at 3 months (64% vs. 40%, p<0.05) and 6 months (67% vs. 42%, p<0.05) after discharge. CONCLUSIONS: The outcomes and clinical parameters were better for SAT during thrombolytic procedures for acute intracranial artery occlusions than for AMCD for up to 6 months. However, some device-related complications occurred during stent interventions.

BACKGROUND: This study evaluated the relationships between endogenous estrogen levels and vascular risk factors in healthy men and women. METHODS: Demographics and laboratory data were collected from normotensive subjects (123 men and 154 women) in their thirties, forties and fifties who had normal laboratory profiles and no cardiovascular risk factors. Initially, estradiol, low-density lipoprotein (LDL)-cholesterol, triglyceride, and high-density lipoprotein (HDL)-cholesterol, systolic and diastolic blood pressure (SBP and DBP), NO2/NO3, homocysteine, and body mass index (BMI) were measured. Then, the relationships between estradiol and the evaluated items were analyzed with comparison of means and correlation, and stepwise multiple regression analysis based on genders and age-groups. RESULTS: Estradiol levels decreased with aging in women. Lower LDL and triglyceride, higher HDL levels, and lower SBP and DBP observed in women were correlated with decreasing age as well as increasing estradiol level. On the multivariate analysis, however, estradiol levels were negatively correlated with the changes in SBP, DBP, and triglyceride among the lipid variables. BMI was positively related with the increase of SBP and DBP and the estradiol levels. Although higher NO2/NO3 and lower homocysteine levels were observed in women than men, the NO2/NO3 and homocysteine levels had no significant correlation with estradiol changes. CONCLUSION: The study observed the beneficial relationships between endogenous estrogen, and blood pressures and lipids in healthy women. The estrogen-related benefits observed in this study were lower TG levels, SBP, and DBP in young women than those in older women or in men.

A 28-year-old primi gravida visited our department at 20 weeks gestation. The ultrasound screening revealed twin gestation, and follow up screening revealed a bilobed large fetal neck mass in the 1st twin. We measured thyroid volume with ultrasound which was 5.072 cm3. Other fetal organs appeared normal. Cordocentesis was performed for fetal thyroid function and congenital hypothyroidism was confirmed. In addition, maternal thyroid hormones were checked. The other fetus was normal. Thyroid stimulating hormone (TSH) in the maternal serum was increased, but thyroxine (T3) was (within normal range). Two weeks later, we checked TSH and free T4 in amniotic fluid and administered intra-amniotic thyroxine (200 ?g). We repeated the procedures 2 more times in two consecutive weeks. After 3 intra-amniotic thyroxine injection, follow-up cordocentesis revealed euthyroid status of the fetus. Although the thyroid gland had decreased in size and volume, it was still goitrous. At 36 weeks of gestation, the patient was admitted for preterm premature rupture of the membranes and the twin was delivered vaginally. The 1st twin was proved as an euthyroid status and antithyroid antibody was not detected. During the 3 years follow up, the baby had no considerable developmental problem. The intrauterine recognition and treatment of congenital goitrous hypothyroidism may not only reduce the obstetric complications associated with large goiters, but possibly improve the prognosis for normal growth and mental development of affected fetuses.
