ABSTRACT
Objectives@#Ewha Womans University launched an on-campus Coronavirus disease-19 (COVID-19) response system called Ewha Safety Campus (ESC) Project in collaboration with the Seegene Inc. RTPCR diagnostic tests for COVID-19 were proactively provided to the participants. This study examines the effectiveness of the on-campus testing strategy in controlling the reproduction number (Rt ) and identifying student groups vulnerable to infection. @*Methods@#The ESC project was launched on March 2, 2022, with a pilot period from Feb 22 to March 1, 2022—the peak of the Omicron variant wave. We collected daily data on the RT-PCR test results of the students of Ewha Womans University from Mar 2 to Apr 30, 2022. We daily calculated Rt and compared it with that of the general population of Korea (women, people aged 20–29 years, and Seoul residents). We also examined the students vulnerable to the infection based on the group-specific Rt and positivity rate. @*Results@#A lower Rt was observed about 2 weeks after the implementation of the ESC Project than that of the general population. The lower Rt persisted during the entire study period. Dormitory residents had a higher Rt . The positivity rate was higher in students who did not comply with quarantine guidelines and did not receive the second dose of the vaccine. @*Conclusion@#The study provides scientific evidence for the effectiveness of the on-campus testing strategy and different infection vulnerabilities of students, depending on dormitory residence, compliance with the quarantine guidelines, and vaccination.
ABSTRACT
Patients with diabetes mellitus are highly susceptible to cardiovascular complications, which are directly correlated with cardiovascular morbidity and mortality. In addition to coronary artery disease, there is growing awareness of the risk and prevalence of heart failure (HF) in patients with diabetes. Echocardiography is an essential diagnostic modality commonly performed in patients with symptoms suggestive of cardiovascular diseases (CVD), such as dyspnea or chest pain, to establish or rule out the cause of symptoms. Conventional echocardiographic parameters, such as left ventricular ejection fraction, are helpful not only for diagnosing CVD but also for determining severity, treatment strategy, prognosis, and response to treatment. Echocardiographic myocardial strain, a novel echocardiographic technique, enables the detection of early changes in ventricular dysfunction before HF symptoms develop. This article aims to review the role of echocardiography in evaluating CVD in patients with diabetes mellitus and how to use it in patients with suspected cardiac diseases.
ABSTRACT
Carbon monoxide (CO) is a known gaseous bioactive substance found across a wide array of body systems. The administration of low concentrations of CO has been found to exert an anti-inflammatory, anti-apoptotic, anti-hypertensive, and vaso-dilatory effect. To date, however, it has remained unknown whether CO influences atrial natriuretic peptide (ANP) secretion. This study explores the effect of CO on ANP secretion and its associated signaling pathway using isolated beating rat atria. Atrial perfusate was collected for 10 min for use as a control, after which high atrial stretch was induced by increasing the height of the outflow catheter. Carbon monoxide releasing molecule-2 (CORM-2; 10, 50, 100 µM) and hemin (HO-1 inducer; 0.1, 1, 50 µM), but not CORM-3 (10, 50, 100 µM), decreased high stretch-induced ANP secretion. However, zinc porphyrin (HO-1 inhibitor) did not affect ANP secretion. The order of potency for the suppression of ANP secretion was found to be hemin > CORM-2 >> CORM-3. The suppression of ANP secretion by CORM-2 was attenuated by pretreatment with 5-hydroxydecanoic acid, paxilline, and 1H-[1,2,4] oxadiazolo [4,3-a] quinoxalin-1-one, but not by diltiazem, wortmannin, LY-294002, or NG-nitroL-arginine methyl ester. Hypoxic conditions attenuated the suppressive effect of CORM-2 on ANP secretion. In sum, these results suggest that CORM-2 suppresses ANP secretion via mitochondrial K ATP channels and large conductance Ca 2+ -activated K+ channels.
ABSTRACT
Background@#and Purpose: The Korean-Color Word Stroop Test: Color Reading (K-CWST:CR) included in the Seoul Neuropsychological Screening Battery, 2nd Edition (SNSB-II) examines inhibitory control deficit. It provides normative data for both 60- and 120-second conditions, but the validity of the 60-second condition has not yet been proven. This study examined the validity of the 60-second condition by observing concordance between the performances in cognitively normal, MCI, and mild dementia groups. @*Methods@#There were 1,336 patients performed the SNSB-II, including the K-CWST: CR.Based on the cognitive test results, activities of daily living, and clinical interview, the patients were assigned to normal cognition (n=104), MCI (n=884), or mild dementia (n=348) groups. Abnormal performance on the K-CWST: CR was operationally defined as 1SD below the normative mean. The receiver operating characteristic curve analyses were conducted to compare the discriminability between the 60- and 120-second conditions. @*Results@#The percentages of abnormal performance in the MCI group were 41.5% and 42.3%, and those in the mild dementia group were 82.7% and 82.4% for the 60- and 120-second conditions, respectively. The areas under the curve for the 60- and 120-seconds were as follows; 0.80 and 0.81 in differentiating normal from MCI; 0.95 and 0.96 in normal from mild dementia; and 0.77 and 0.77 in MCI from mild dementia. @*Conclusions@#The 60-second condition of the K-CWST showed very similar results, not statistically different from the 120-second condition. Therefore, the 60-second condition could be used interchangeably with the 120-second condition in a clinical setting.
ABSTRACT
Background@#and Purpose: Everyday Cognition (ECog) has been widely used to differentiate individuals with mild cognitive impairment (MCI) and dementia from normal elderly individuals. It has also been used to assess subjective cognitive decline (SCD). This study investigated the feasibility of using ECog as a screening measure for SCD in communitydwelling elderly individuals. @*Methods@#The participants included 84 older adults with and 93 without SCD living in the community. These 2 groups were classified based on their response (“yes” or “no”) to the question “Do you perceive memory or cognitive difficulties?” All participants were evaluated using the Korean-Mini Mental State Examination (K-MMSE), Short form of the Geriatric Depression Scale (SGDS), and the Korean version of Everyday Cognition (K-ECog). @*Results@#The scores of all participants were within the normal range on the K-MMSE and SGDS. The total K-MMSE score did not differ significantly between the 2 groups after controlling for age, education, and depression. The scores of SCD group were significantly higher than those of the non-SCD group for memory, language, and executive function:planning domains, as well as K-ECog total score. Receiver operating characteristic curve analysis revealed that the K-ECog total score was effective in moderately differentiating between subjects with and without SCD (area under the curve: 0.73). @*Conclusions@#ECog is a feasible and useful screening measure for SCD in older adults living in the community, and can be used to assess the full spectrum of cognitive and functional deficits, ranging from SCD to MCI and dementia.
ABSTRACT
Background and Objectives@#Cardiac myxoma is the most frequent benign cardiac tumor that can result in cardiac and systemic symptoms. We investigated clinical and echocardiographic characteristics of patients with cardiac masses suggesting myxoma. @*Methods@#We investigated 265 consecutive patients with an echocardiographic diagnosis of cardiac myxomas in 4 teaching hospitals in Korea. @*Results@#The mean age was 61±16 years and 169 patients (63.8%) were female. The most frequent referral reason for echocardiography was an evaluation of cardiac symptoms (43.4%). Tumors were incidentally detected in 82 patients (30.9%). Left atrium (LA) was the most frequently involved site (84.5%) and 19 patients (7.2%) had non-atrial tumors. The mean tumor size was 38.7×26.0 mm (range, 4–96 mm). Of 186 patients (70.2%) who had pathological diagnosis, 174 (93.5%) were confirmed with myxoma, 8 (4.3%) with other tumors and 4 (2.2%) with thrombi. Compared to myxoma, smaller size (20.4×12.6 mm vs. 41.4×27.6 mm, p<0.01) and non-LA location (87.5% vs. 10.5%, p<0.001) were associated with non-myxoma tumors, and more frequent atrial fibrillation (AF, 75.0% vs. 7.0%, p<0.001) and larger LA diameter (55.0±14.6 mm vs. 41.3±7.7 mm, p=0.001) were related to thrombi. @*Conclusions@#Of 265 patients with an echocardiographic diagnosis with cardiac myxomas, 174 (65.7%) were surgically confirmed with myxomas. Compared with cardiac myxoma, other tumors were smaller and more frequently found in non-atrial sites. Thrombi were associated with AF and larger LA diameter.
ABSTRACT
Background/Aims@#Pheochromocytoma and paraganglioma (PPGL) are catecholamine-producing tumors that can cause blood pressure (BP) elevation and cardiovascular complications. Clinical presentation of these tumors may be changed through widespread use of imaging studies, which enables detection of PPGLs before onset of symptoms. We investigated clinical profiles of patients with surgically resected PPGLs. @*Methods@#From 2005 to 2017, 111 consecutive patients with surgically resected PPGLs in two tertiary hospitals in Korea were studied. @*Results@#Mean age was 52 ± 16 years, 57 patients (51.4%) were male and 54 (48.6%) were hypertensive. Twenty-nine PPGLs (26.1%) were extra-adrenal paragangliomas. Sixteen (14.4%) and seven patients (6.3%) (Group 1, n = 23) were diagnosed during work-up of hypertension and transient cardiomyopathy respectively, and the remainder (Group 2, n = 88) were incidentalomas detected during routine abdominal imaging. Patients in the Group 1 were younger and more frequently symptomatic, and had higher BPs, heart rates and levels of urinary catecholamines than those in the Group 2. Paragangliomas were less frequent and secretion of epinephrine and metanephrine was more predominant in the Group 1 than in Group 2. After the surgical resections, 18.2% of patients still needed antihypertensive medications. @*Conclusions@#Out of 111 patients with surgically resected PPGLs, 88 (79.3%) were diagnosed as incidentalomas. Seven patients presented with transient cardiomyopathy and 16 with hypertension. Tumor location and secretion of catecholamine may vary depending on the presence of symptoms.
ABSTRACT
Objective@#To evaluate the predictive performance of optic nerve sheath thickness (ONST) on the outcomes of traumatic brain injury (TBI) and to compare the inter-observer agreement To evaluate the predictive performance of optic nerve sheath thickness (ONST) for traumatic brain injury (TBI) and to compare the predictive performance and inter-observer agreement between ONST and optic nerve sheath diameter (ONSD) on facial computed tomography (CT). @*Methods@#We retrospectively enrolled patients with a history of facial trauma and who underwent both facial CT and brain CT. Two reviewers independently measured ONST and ONSD of each patient using facial CT images. Final brain CT with clinical outcome was used as the reference standard for TBI. Multivariate logistic regression analyses, receiver operating characteristic (ROC) curves, and intraclass correlation coefficients were used for statistical analyses. @*Results@#Both ONST (P=0.002) and ONSD (P=0.001) on facial CT were significantly independent factors to distinguish between TBI and healthy brains; an increase in ONST and ONSD values corresponded with an increase in the risk of TBI by 8.9- and 7.6-fold, respectively. The predictive performances of the ONST (sensitivity, 96.2%; specificity, 94.3%; area under the ROC curve, 0.968) and ONSD (sensitivity, 92.6%; specificity, 90.2%; area under the ROC curve, 0.955) were excellent and exhibited similar sensitivity, specificity, and area under the curve (P=0.18–0.99). Interobserver and intraobserver intraclass correlation coefficients for ONST were significantly higher than those for ONSD (all P<0.001). @*Conclusion@#ONST on facial CT is a feasible predictor of TBI and demonstrates similar performance and superior observer agreement than ONSD. We recommend using ONST measurements to assess the need for additional brain CT scans in TBI-suspected cases.
ABSTRACT
BACKGROUND AND OBJECTIVES@#Acute myocardial infarction-related heart failure (HF) is associated with poor outcome. This study was designed to investigate the usefulness of global longitudinal strain (GLS), global circumferential strain (GCS) and mean longitudinal strain of left anterior descending artery territory (LSant) measured by 2-dimensional speckle tracking echocardiography (2D STE) in prediction of acute anterior wall ST-segment elevation myocardial infarction (ant-STEMI)-related HF.@*METHODS@#A total of 171 patients with ant-STEMI who underwent successful primary coronary intervention and had available 2D STE data were enrolled. Patients were divided into 3 groups: in-hospital HF, post-discharge HF, and no-HF groups.@*RESULTS@#In-hospital and post-discharge HF developed in 39 (22.8%) and 13 (7.6%) of patients, respectively and 113 patients (69.6%) remained without HF. Multivariate analysis showed that GLS was the only factor significantly associated with the development of in-hospital HF. For post-discharge HF, LSant was the only independent predictor. Other echocardiographic or laboratory parameters did not show independent association with the development of ant-STEMI-related HF.@*CONCLUSIONS@#GLS is a powerful echocardiographic parameter related to development of in-hospital HF and LSant was significantly associated with post-discharge HF in patients with successfully reperfused ant-STEMI.
ABSTRACT
PURPOSE@#Contrast media extravasation (CME) is an adverse reaction after administration of contrast media during CT examinations. The purpose of this study was to evaluate the frequency, management, and outcomes of extravasations and to assess the risk factors for CME in the emergency department (ED) and the ward.@*MATERIALS AND METHODS@#This retrospective study was conducted at a single academic urban hospital from January 2013 to December 2015. We analyzed the medical records of all patients who experienced CME after undergoing a CT scan. We compared the patients' age, sex, underlying disease, injection site, injection flow rate, time of CT examination, type of CT examination, and severity of injury between those in the ED and the ward.@*RESULTS@#CME occurred in 41 (0.36%) of 114767 patients, which included 16 (0.34%) in the ED and 25 (0.37%) in the ward. Both groups were more frequent in those aged older than 60 years and in female. Additionally, the abdominopelvic CT type and 2–3 mL/s as the injection rate were more common in both groups. However, CME was more frequent during the nighttime (10, 62.5%) in the ER, while it was more common in the daytime (14, 56.0%) in the ward. Severe complications were more frequent in the ER (9, 56.3%) compared with the ward (8, 32.8%). There were no significant differences in CME between the ED and the ward. When comparing the clinical manifestations in the mild and severe groups, the antecubital fossa (33.3% and 0%, respectively; p = 0.013) for the injection site and abdominopelvic CT (41.7% and 82.4%, respectively; p = 0.012) and CT angiography (41.7% and 5.87%, respectively; p = 0.014) for the CT examination showed significant differences between the mild and severe groups.@*CONCLUSION@#In this study, there were no significant clinical differences in CME between the ED and ward. Thus, prevention is more important than the place of admission. Radiologists and emergency physicians should pay attention to CME in the ED because it frequently occurs at night and results in more severe complications.
ABSTRACT
BACKGROUND AND PURPOSE: The Korean version of Story Memory (SM) in the Korean-Mini Mental State Examination, 2nd Edition: Expanded Version (K-MMSE-2: EV) was developed. Based on the SM, we additionally developed a full version of SM including delayed recall (DR) and recognition adding to immediate recall (IR). This study aimed to examine the reliabilities and validities of the newly developed SM in the K-MMSE-2: EV and its full version. METHODS: Ninety-five healthy elderly individuals (HE), 90 patients with amnestic mild cognitive impairment (aMCI), and 53 patients with dementia of the Alzheimer's type (DAT) participated in the study. They were administered the full version of SM with the Seoul Verbal Learning Test-Elderly's version (SVLT-E) and Rey Complex Figure Test (RCFT). In addition, the SM was re-administered to 51 participants after a 5-week interval. Two clinical neuropsychologists independently rated the performance of 50 participants. RESULTS: The test-retest reliabilities of the IR, DR, and recognition of the SM were statistically significant. The inter-rater reliabilities (Cohen's kappa) were high (0.87–1.00) for all the measures. The IR, DR, and recognition of SM had significant positive correlations with those of the SVLT-E and RCFT. Significant group differences in IR and DR of SM were found among the HE, aMCI, and DAT groups. The recognition scores were significantly different between the aMCI and DAT groups, but not between the HE and aMCI groups. CONCLUSIONS: The newly developed full version of SM in the K-MMSE-2: EV was proven to be a reliable and valid memory measure for clinical use.

BACKGROUND: In the early diagnosis of dementia, an important factor is the evaluation of activities of daily living. The Everyday Cognition (ECog) scale was developed to measure functional changes that are the everyday correlates of specific neuropsychological impairments. This study aimed to examine the validity of the Korean version of Everyday Cognition (K-ECog). METHODS: The participants were 268 cognitively normal older adults (NA), 151 amnestic mild cognitive impairment (aMCI), and 77 dementia of the Alzheimer's type (DAT). The Korean-Mini Mental State Examination (K-MMSE), Korean-Montreal Cognitive Assessment (K-MoCA), and Short form of the Geriatric Depression Scale (SGDS) were administered to all the participants. The K-ECog and Korean-Instrumental Activities of Daily Living (K-IADL) were rated by their informants. RESULTS: Internal consistency (Cronbach's α) of K-ECog global function was 0.93, and its test-retest reliability (Pearson's r) was 0.73. K-ECog was significantly correlated with K-IADL (0.66), K-MMSE (−0.38), and K-MoCA (−0.26). Confirmatory factor analysis of K-ECog yielded seven factor model that the original ECog proposed. K-ECog global score and six domain scores were significantly different across the NA, aMCI, and DAT groups. Receiver operating characteristic curve analyses showed that K-ECog effectively differentiated aMCI and DAT patients from NA, suggesting that K-ECog is as sensitive for detecting functional impairments as K-IADL. The proposed optimal cut-off score to differentiate aMCI from NA was 1.41. CONCLUSION: K-ECog is proven reliable and valid for clinical use. K-ECog can be used to distinguish very early stages of impaired ADL and cognitive impairment in the community.

PURPOSE: This study was conducted to identify nurses'critical thinking disposition, self-leadership and clinical competency in small to medium sized hospitals less than 300beds. METHODS: Data were collected using the questionnaire from 227 nurses in Incheon city and Gyeonggi province from March to April, 2017. The data were analyzed using t-test, ANOVA and Scheffé's test to identify differences in critical thinking disposition, self-leadership and clinical competency. Pearson correlation coefficients were used to identify the correlation among the study variables, and multiple regression was used to identify factors contributing to clinical competency. RESULTS: There were significant differences in critical thinking disposition according to age, marital status, clinical career, career in currently working department and education about leadership. Significant differences in self-leadership were identified according to marital status, work position, working department, work type, education about leadership, and turnover intention. Clinical competency was significantly different depending on age, education, monthly income, work position, career in currently working department, work type, education about critical thinking disposition and education about leadership. Clinical competency was positively correlated critical thinking disposition and self-leadership. Critical thinking deposition, monthly income and self-leadership explained 30.1% of clinical competency of nurses working in small to medium sized hospitals. CONCLUSION: The results of this study suggest that we need to improve nurses' critical thinking disposition, self-leadership, and the clinical competency.

OBJECTIVE: The aim of this study was to identify the clinical characteristics and risk factors associated with the admission of patients in the emergency department (ED) within 30 days after discharge. METHODS: A retrospective, observational study was conducted on adult patients presenting with abdominal pain to the ED of a single, urban, university hospital, between January 2014 and December 2015, who revisited the ED within 30 days after discharge. Data was collected on the emergency severity index level, time to contact doctors, physical examination, laboratory tests, use of computed tomography (CT), and patient disposition on revisitation. The primary outcome was hospital admission following an ED revisit in the 30-day period after the first visit. RESULTS: During the study period, 19,480 patients visited the ED with the chief complaint of abdominal pain, and 13,577 were discharged. A total of 251 patients (1.29%) revisited the ED within 30 days, of which 89 were eligible for the study. The primary outcome was associated with not performing a CT scan on the initial visit and an increased C-reactive protein (CRP) value. Receiver operating characteristic curve analysis showed that a cut-off baseline CRP value of >0.35 mg/dL can predict the primary outcome with a sensitivity and specificity of 75% and 62.1%, respectively (area under the curve, 0.701; 95% confidence interval, 0.569–0.833; P=0.007). CONCLUSION: An increased CRP value and not performing abdominal CT were associated with a higher rate of admission following ED revisits of patients with abdominal pain. Future prospective studies on the role of abdominal CT imaging in patients presenting to the ED with abdominal pain will be needed.

PURPOSE: To evaluate the association between neutrophil-to-lymphocyte ratio (NLR) and occurrence of aspiration pneumonia in drug intoxication (DI) patients in the emergency department (ED) and to evaluate the relationship between NLR and length of hospital admission/intensive care unit (ICU) admission. METHODS: A total of 466 patients diagnosed with DI in the ED from January 2016 to December 2017 were included in the analysis. The clinical and laboratory results, including NLR, were evaluated as variables. NLR was calculated as the absolute neutrophil count/absolute lymphocyte count. To evaluate the prognosis of DI, data on the development of aspiration pneumonia were obtained. Also, we evaluated the relationship between NLR and length of hospital admission and between NLR and length of ICU admission. Statistically, multivariate logistic regression analyses, receiver-operating characteristic (ROC) curve analysis, and Pearson's correlation (ρ) were performed. RESULTS: Among the 466 DI patients, 86 (18.5%) developed aspiration pneumonia. Multivariate logistic regression analysis revealed NLR as an independent factor in predicting aspiration pneumonia (odds ratio, 1.7; p=0.001). NLR showed excellent predictive performance for aspiration pneumonia (areas under the ROC curves, 0.815; cut-off value, 3.47; p 3.47).

BACKGROUND AND PURPOSE: The risk of vitamin D deficiency varies with the season. The frequency of vitamin D deficiency in migraine patients and its association with migraine are unclear. METHODS: We retrospectively evaluated first-visit migraine patients between January 2016 and May 2017, and investigated the demographics, season, migraine subtypes, frequency, severity, and impact of migraine, psychological and sleep variables, climate factors, and vitamin D levels. The nonfasting serum 25-hydroxyvitamin D concentration was measured to determine the vitamin D level, with deficiency of vitamin D defined as a concentration of < 20 ng/mL. RESULTS: In total, 157 patients with migraine aged 37.0±8.6 years (mean±standard deviation) were analyzed. Their serum level of vitamin D was 15.9±7.4 ng/mL. Vitamin D deficiency was present in 77.1% of the patients, and occurred more frequently in spring and winter than in summer and autumn (89.1%, 85.7%, 72.4%, and 61.7%, respectively; p=0.008). In multivariate Poisson regression analysis, monthly headache was 1.203 times (95% confidence interval=1.046–1.383, p=0.009) more frequent in patients with vitamin D deficiency than in those without deficiency after adjusting for demographics, season, migraine subtype, depression, anxiety, and sleep quality. These associations were consistently noted in subgroup analysis of episodic migraine (odds ratio=1.266, p=0.033) and chronic migraine (odds ratio=1.390, p=0.041). CONCLUSIONS: Our study found that a larger number of monthly days with headache was related to vitamin D deficiency among migraineurs. Future studies should attempt to confirm the causal relationship between vitamin D deficiency and migraine.

OBJECTIVE: Most patients with head trauma require brain computed tomography (CT) in the emergency department. However, the requirement for facial CT remains controversial. The aim of this study was to evaluate the diagnostic value of brain CT alone for detection of facial fractures and its ability to determine the requirement for additional facial CT. METHODS: This retrospective multicenter study was conducted in two tertiary hospitals in Seoul, Republic of Korea, between January 2014 and December 2015. Data were collected from the medical records of adult patients (aged over 18 years) who had undergone both brain and facial CT on the same day as their presentation to the emergency department with blunt trauma to the head and face. The same radiologist analyzed all brain and facial CT images. RESULTS: Eight hundred and sixty patients (668 men, 192 women; mean age 48.60±18.2 years) were identified to have had facial fractures. There was a statistically significant predominance of men but not of any particular age group. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of brain CT were 83.72%, 98.87%, 97.17%, 92.92%, and 94.08%, respectively. CONCLUSION: These findings suggest that brain CT has high diagnostic value for detection of upper facial bone fractures with high accuracy and can aid emergency physicians when determining the requirement for additional facial CT.

Bannayan-Riley-Ruvalcaba syndrome (BRRS) is one of the phosphatase and tensin homolog hamartoma tumor syndrome with a PTEN gene mutation. It is a rare dominant autosomal disorder characterized by cutaneous lipomas, macrocephaly, intestinal polyps, and developmental delay. Diagnosing this syndrome is important, because it may represent the pediatric phenotype of Cowden syndrome, in which there is an increased risk for malignant tumors in children. Until now, the prevalence of BRRS is unknown. Several dozen cases have been reported in the medical literature, but no case has been reported in Korea. Here we report a case of a 19-year-old girl who was diagnosed with BRRS because of macrocephaly, intellectual disability, and intestinal polyps. Her mother had similar findings and a PTEN mutation. Neither patient had mutations detected by conventional mutation-detection techniques, but a PTEN gene deletion was demonstrated by chromosomal microarray analysis.
