ABSTRACT
Purpose@#The purpose of this study was to build a structural model to explain subjective happiness in menopausal middle-aged women. @*Methods@#A hypothesized model was established based on literature review. Emotional stress and family support were included as exogenous variables whereas active coping, resilience, and subjective happiness were included as endogenous variables. This study was conducted using data from 228 middle-aged menopausal women living in the Republic of Korea that fit the structural equation model. The data were analyzed using SPSS 27.0 and Amos 20.0 programs. @*Results@#Emotional stress was revealed as the most influential factor affecting subjective happiness. Emotional stress had a negative direct, indirect, and total effect on subjective happiness. Family support had positive indirect and total effects, and resilience had positive direct and total effects on subjective happiness. @*Conclusion@#To enhance subjective happiness of menopausal middle-aged women, nursing interventions, which reduce emotional stress and improve resilience, should be provided. Family-level nursing intervention should be also developed to promote family support.
ABSTRACT
Background@#In 2017, we established an airway call (AC) team composed of anesthesiologists to improve emergency airway management outside the operating room. In this retrospective analysis of prospectively collected data from the airway registry, we describe the characteristics of patients attended to and practices by the AC team during the first 4 years of implementation. @*Methods@#All AC team activations in which an airway intervention was performed by the AC team between June 2017 and May 2021 were analyzed. @*Results@#In all, 359 events were analyzed. Activation was more common outside of working hours (62.1%) and from the intensive care unit (85.0%); 36.2% of AC activations were due to known or anticipated difficult airway, most commonly because of acquired airway anomalies (n = 49), followed by airway edema or bleeding (n = 32) and very young age (≤ 1 years; n = 30). In 71.3% of the cases, successful intubation was performed by the AC team at the first attempt. However, three or more attempts were performed in 33 cases. The most common device used for successful intubation was the videolaryngoscope (59.7%). Tracheal intubation by the AC team failed in nine patients, who then required surgical airway insertion by otolaryngologists. However, there were no airway-related deaths. @*Conclusions@#When coupled with appropriate assistance from an otolaryngologist AC system, an AC team composed of anesthesiologists could be an efficient way to provide safe airway management outside the operating room.
ABSTRACT
Objective@#If empirical antibiotics must be administered, the pharmacy needs to deliver the drug to emergency patients as soon as possible. The purpose of this study was to investigate the impact of the installation of an automated dispensing cabinet system in an emergency center. @*Methods@#A retrospective study was conducted through the analysis of medical records in an emergency medical center for 12 months before and after the installation of the system. The order-to-antibiotic time and door-to-antibiotic time were collected retrospectively through a system log analysis. For the satisfaction survey, nursing providers who use the dispensing system were administered a survey questionnaire related to the system. @*Results@#This study covered 1,292 prescriptions before and 1,377 after the introduction of the system in the emergency center. It was observed that the average time from the order-to-drug administration decreased (48.7±57.9 vs. 41.1±52.3, P=0.001) after the introduction of the system. The door-to-drug administration time also showed a decrease (293.6±260.2 vs. 267.4±221.1, P=0.006). A satisfaction survey was conducted on 38 users of the system who agreed to participate and respond. The score of the satisfaction survey was 3.63±0.44. The user response showed that they were most satisfied with the prevention of medication errors (4.00±0.62) and system control (4.00±0.57). @*Conclusion@#The automated dispensing cabinet system in an emergency center can shorten the order-to-drug time and door-to-drug time. In addition, it helps to improve the satisfaction and work efficiency of emergency medical workers related to medication dispensation.
ABSTRACT
Objectives@#：A recent study of a European sample implied that the 14 genes previously known to be related with schizophrenia may play little roles. But much work remains before dismissing these genes from their connection to schizophrenia. This is a pilot study for family based association test (FBAT) analysis of estrogen metabolism gene in a Korean population with schizophrenia. @*Methods@#：27 probands with schizophrenia were recruited with their parents and siblings. The subjects were interviewed using Korean versions of diagnostic interview for genetic studies and family interview for genetic studies. We analyzed 2 single nucleotide polymorphism (SNP) of ESR1, COMT gene. We performed FBAT and linkage disequilibrium analyses for each individual SNP. @*Results@#：We found a significant SNP of ESR1 gene in chromosome 6 for the qualitative phenotype of schizophrenia. That result was replicated for the quantitative phenotype of apparent onset, apparent onset of psychosis, and first treatment age. We also found a significant SNP of ESR1 gene in chromosome 6 for the quantitative phenotype of any delusions. @*Conclusions@#：Our results show that quantitative traits such as age of onset, any delusions, and any hallucinations could be continuous with qualitative trait in schizophrenia. But we should be very cautious because there are clear limitations in some nominal number of SNPs and the small incomplete pedigrees. In the future, FBAT analyses in families with subtyped schizophrenic probands according to personality, working memory, cognition will facilitate fine mapping analyses for searching candidate genes of schizophrenia.
ABSTRACT
Purpose@#The purpose of this study was to verify influencing factors affecting service quality provided by caregivers working for the elderly with dementia. @*Methods@#Data were collected using a self-reported questionnaire from 214 caregivers in a long-term care facility in D city. The data were analyzed with service quality, dementia knowledge, work value, and job performance confidence. For data analysis, the descriptive statistics, t-test, one-way ANOVA, Pearson correlation coefficients, and multiple regression were performed using SPSS/WIN 21.0 program. @*Results@#There were significant differences in service quality depending on the health status. Factors influencing service quality were work value, and job performance confidence with R2 value of 38%. The highly influencing factors were work value, and job performance confidence. @*Conclusion@#The results of this study indicate that the effort to improve the service quality of caregivers should focus on work value and job performance confidence.
ABSTRACT
Background@#The accurate pathologic diagnosis and subtyping of high-grade endometrial carcinoma are often problematic, due to its atypical and overlapping histopathological features. @*Methods@#Three pathologists reviewed 21 surgically resected cases of advancedstage endometrial carcinoma. The primary diagnosis was based only on hematoxylin and eosin stained slides. When a discrepancy arose, a secondary diagnosis was made by additional review of immunohistochemical (IHC) stains. Finally, three pathologists discussed all cases and rendered a consensus diagnosis. @*Results@#The primary diagnoses were identical in 13/21 cases (62%). The secondary diagnosis based on the addition of IHC results was concordant in four of eight discrepant cases. Among four cases with discrepancies occurring in this step, two cases subsequently reached a consensus diagnosis after a thorough discussion between three reviewers. Next-generation sequencing (NGS) study was performed in two cases in which it was difficult to distinguish between serous carcinoma and endometrioid carcinoma. Based on the sequencing results, a final diagnosis of serous carcinoma was rendered. The overall kappa for concordance between the original and consensus diagnosis was 0.566 (moderate agreement). @*Conclusions@#We investigated stepwise changes in interobserver diagnostic reproducibility in advanced-stage endometrial carcinoma. We demonstrated the utility of IHC and NGS study results in the histopathological diagnosis of advanced-stage endometrial carcinoma.
ABSTRACT
Orthodontic treatment of posterior bite collapse due to early loss of molars and the consequent drift of adjacent teeth is complicated. When the posterior bite collapse occurs in patients with facial asymmetry, both transverse and vertical compensation are necessary for camouflage orthodontic treatment. In such cases, posterior maxillary segmental osteotomy (PMSO) can be an effective alternative procedure that simplifies the orthodontic treatment and shows long-term stability through dental compensation within the alveolar bone housing. This case report aimed to describe the orthodontic treatment of maxillary occlusal plane canting caused by severely extruded maxillary teeth in a patient with skeletal facial asymmetry that was corrected with PMSO along with protraction of the lower second molar to replace the space of the extracted first molar. The treatment duration was 18 months, and stable results were obtained after 2 years of retention.
ABSTRACT
In epilepsy-aphasia spectrum (EAS) disorders, mutations in the glutamate receptor ionotropic N-methyl-D-aspartate type subunit 2A (GRIN2A) have become important for screening the disease. Research into the phenotypic variability of several types of neurologic impairment involving these mutations is in progress. However, the non-neurological problems related to these mutations are poorly understood. EAS disorders usually have epileptic, cognitive, or behavioral manifestations. In this case report, we present a female patient with epilepsy, delay in expressive language and social development, and intellectual disability with low intelligence quotient and memory quotient, but normal motor development. Through genetic analysis, she was found to have a missense and a nonsense mutation in GRIN2A (c.1770A>C; p.Lys509Asn and c.3187G>T; p.Glu1063*, respectively) and we consider the nonsense mutation as ‘pathogenic variant’. She was also discovered to have congenital hypothyroidism, growth hormone deficiency and Rathke’s cleft cyst in the brain, which were previously unknown features of GRIN2A mutation. Our findings should widen understanding of the spectrum of GRIN2A phenotypes, and emphasize the need for more research into the association between GRIN2A mutations and non-neurologic clinical presentations.

ABSTRACT
BACKGROUND: This study aimed to analyze the association of low vitamin D status with thyroid autoimmunity and dysfunction in the Korean population according to sex and menopausal status in women. METHODS: This study was based on the data acquired from the 6th Korea National Health and Nutrition Examination Survey. We enrolled 4,356 subjects who had data of thyroid function, antithyroid peroxidase antibody (TPOAb), and serum 25-hydroxyvitamin D (25[OH]D) levels. We excluded subjects who were pregnant and who had a history of thyroid disease or thyroid cancer, and those with transient thyroid dysfunction who tested negative for TPOAb (TPOAb[−]). RESULTS: TPOAb positivity (TPOAb[+]) with thyroid dysfunction (subclinical and overt hypothyroidism) was more prevalent in the vitamin D deficient group than in the vitamin D insufficient and sufficient groups including premenopausal (P=0.046) and postmenopausal women (P=0.032), although no significant differences were observed in men. The mean serum 25(OH)D level was significantly lower in the TPOAb(+) with thyroid dysfunction group than in the TPOAb(+) with euthyroidism and TPOAb(−) groups of premenopausal women (P=0.001), although no significant differences were observed in men and postmenopausal women. Multivariate binary logistic regression analysis, adjusted for age, body mass index, and current smoking status, showed that vitamin D insufficiency and deficiency were significantly associated with TPOAb(+) with thyroid dysfunction in premenopausal women (P<0.001), although no significant associations were observed in men and postmenopausal women. CONCLUSION: Low vitamin D status was significantly associated with thyroid autoimmunity and dysfunction in the Korean population, especially in premenopausal women.

BACKGROUND: Causal hypotheses suggest that alcohol-related disorders may also cause psychiatric disorders and problems, or vice versa. The association between alcohol consumption and mental health is important from both research and therapeutic viewpoints. Therefore, we aimed to analyze the association between alcohol consumption and mental health (perceived stress, depressive mood, suicidal ideation, quality of life) in Korean adults over 19 years old.METHODS: We finally included 5,399 adults who had participated in the Korean National Health and Nutrition Examination Survey in 2015, and analyzed the association between alcohol consumption and mental health, using logistic regression.RESULTS: Perceived stress was associated with alcohol consumption in problem drinkers (odds ratio [OR]=1.35, 95% confidence interval [CI]=1.13–1.61). Depressive mood was associated with alcohol consumption in moderate and problem drinkers (OR=0.90, 95% CI=0.71–1.11 and OR=1.35, 95% CI=1.06–1.70, respectively). Suicidal ideation was not associated with alcohol consumption in moderate and problem drinkers (P=0.063 and P=0.068, respectively). Quality of life was associated with alcohol consumption in moderate and problem drinkers (OR=0.48, 95% CI=0.41–0.57 and OR=0.77, 95% CI=0.66–0.92, respectively).CONCLUSION: We found that moderate drinkers have a lower risk of depressive mood and a higher quality of life as compared to low drinkers. However, problem drinkers have a higher quality of life but a higher risk of perceived stress and depressive mood as compared to low drinkers.

BACKGROUND: Lower back pain (LBP) is the most common musculoskeletal disease in adults over the age of 50. LBP is associated with physical activity and mental health such as depression or suicidal thoughts. We aimed to analyze the association between LBP and mental health and that between physical activity and depressive mood in LBP patients among Korean adults over the age of 50.METHODS: We included 2,681 adults in the analysis, who participated in the 2013 Korean National Health and Nutrition Examination Survey, and used a t-test, logistic regression analysis, and chi-squared test via complex sampling. We analyzed the association between LBP and mental health, various kinds of physical activity, and depressive mood after adjusting for confounding factors.RESULTS: Poor mental health (perception of stress, diagnosis of depression, depressive mood, suicidal thoughts, and suicide attempts) were significantly associated with LBP. The LBP group was 2.077 times more likely to be diagnosed with depression and was 4.666 times more likely to have suicidal thoughts than the control group. Exercise, such as walking, was associated with a reduced risk of depressive mood in subjects with LBP.CONCLUSION: LBP patients were at high risk of being diagnosed with depression, experiencing suicidal thoughts and depressive mood, and attempting suicide. In LBP patients, walking was associated with a reduced depressive mood.

OBJECTIVE@#To evaluate the short-term changes in masticatory muscle activity and mandibular movement patterns after orthognathic surgery in skeletal Class III patients with facial asymmetry.@*METHODS@#Twenty-seven skeletal Class III adult patients were divided into two groups based on the degree of facial asymmetry: the experimental group (n = 17 [11 male and 6 female]; menton deviation ≥ 4 mm) and control group (n = 10 [4 male and 6 female]; menton deviation < 1.6 mm). Cephalography, electromyography (EMG) for the anterior temporalis (TA) and masseter muscles (MM), and mandibular movement (range of motion [ROM] and average chewing pattern [ACP]) were evaluated before (T0) and 7 to 8 months (T1) after the surgery.@*RESULTS@#There were no significant postoperative changes in the EMG potentials of the TA and MM in both groups, except in the anterior cotton roll biting test, in which the masticatory muscle activity had changed into an MM-dominant pattern postoperatively in both groups. In the experimental group, the amount of maximum opening, protrusion, and lateral excursion to the non-deviated side were significantly decreased. The turning point tended to be shorter and significantly moved medially during chewing in the non-deviated side in the experimental group.@*CONCLUSIONS@#In skeletal Class III patients with facial asymmetry, the EMG activity characteristics recovered to presurgical levels within 7 to 8 months after the surgery. Correction of the asymmetry caused limitation in jaw movement in terms of both ROM and ACP on the non-deviated side.
ABSTRACT
BACKGROUND: The purpose of this study is to investigate relationship between the horse racing addiction and the health status indicators. METHODS: Surveys were conducted with visitors of the Korea Racing Association in Gyeonggi-do, from September 1 to September 24, 2017. We used the questionnaire, which contains questions to assess the horse racing addiction, mood depression, health-related quality of life, smoking amount, alcohol dependency, etc. Survey data were analyzed through t-test, chi-square test, logistic regression analysis, and multiple regression analysis by SPSS program (IBM Corp., Chicago, IL, USA). RESULTS: The pathological gambling group was 47.5% (n=38) of the visitors, and they showed a different racecourse use behavior compared to the normal group. In addition, we found that the pathological gambling group had a significantly different health-related quality of life score and a depression score from the normal group, and that the addiction score and the depression score had a linear correlation. CONCLUSIONS: Among the racecourse visitors, the ratio of the pathological gambler was considerably high, and the pathological gambling group showed different health-related quality of life score and a depression score compared to the normal group; especially, the depression score has a significant correlation with horse racing addiction. Therefore, the horse racing association and the health authorities should recognize the seriousness of the horse racing addiction, make an effort to select high risk users, and prepare a program to prevent pathological gambling.

ABSTRACT
Epithelioid angiomyolipoma (EAML) of liver is a rare neoplasm. Hepatic EAML is often misdiagnosed as other neoplasms such as hepatocellular carcinoma due to non-specific clinical and radiologic features. The morphologic features under microscope and immunohistochemistry staining profile are important in the diagnosis EAML. Here, we report a case of 52-year-old man who found 1.2 cm mass in liver by routine checkup. On the impression of hepatocellular carcinoma, lateral sectionectomy of the liver was done. Microscopically, the tumor is composed of predominant epithelioid cells with vascular component and foamy cells. These cells were positive for HMB45, MelanA, and smooth muscle actin and negative for epithelial membrane antigen. The final diagnosis was hepatic EAML.

PURPOSE: Breast cancer has a high prevalence in Korea. To achieve personalized therapy for breast cancer, long-term follow-up specimens are needed for next-generation sequencing (NGS) and multigene analysis. Formalin-fixed paraffin-embedded (FFPE) samples are easier to store than fresh frozen (FF) samples. The objective of this study was to optimize RNA extraction from FFPE blocks for NGS. METHODS: RNA quality from FF and FFPE tissues (n=5), expected RNA amount per unit area, the relationship between archiving time and quantity/quality of FFPE-extracted RNA (n=14), differences in quantitative real-time polymerase chain reaction (qRT-PCR) and NGS results, and comparisons of both techniques with tissue processing at different institutions (n=96) were determined in this study. RESULTS: The quality of RNA did not show any statistically significant difference between paired FF and FFPE specimens (p=0.49). Analysis of tumor cellularity gave an expected RNA amount of 33.25 ng/mm2. Archiving time affected RNA quality, showing a negative correlation with RNA integrity number and a positive correlation with threshold cycle. However, RNA from samples as old as 10 years showed a 100% success rate in qRT-PCR using short primers, showing that the effect of archiving time can be overcome by proper experiment design. NGS showed a higher success rate than qRT-PCR. Specimens from institution B (n=46), which were often stored in a refrigerator for more than 6 hours and fixed without slicing, showed lower success rates and worse results than specimens from the other institutes. CONCLUSION: Archived FFPE tissues can be used to extract RNA for NGS if they are properly processed before fixation. The expected amount of RNA per unit size calculated in this study will be useful for other researchers.

PURPOSE: The purpose of this study was to identify breastfeeding practice with late preterm infants (LPIs), and to determine predictors of exclusive breastfeeding at the 12th week after discharge. METHODS: The participants were 106 mothers of LPIs hospitalized in neonatal intensive care units at two university hospitals. Data were collected between February and October, 2013. Questionnaires included characteristics of LPIs, their mothers, and feeding-related characteristics. Feeding methods were exclusive breastfeeding, mixed feeding, and formula feeding. RESULTS: Exclusive breastfeeding steadily increased from 5.7% at the 1st week to 19.8% at the 12th week, as did formula feeding from 27.3% to 67.9%. Contrarily, mixed feeding decreased from 67.0% at the 1st week to 12.3% at the 12th week. The ratio of formula feeding was higher than that of exclusive breastfeeding over time. Predictors for exclusive breastfeeding were the following: type of delivery (OR=2.96, 95%CI=1.07-8.14), feeding intolerance (OR=3.03, 95%CI=1.26-7.25) and feeding method during hospitalization (OR=7.84, 95%CI=3.15-19.53). CONCLUSION: In order to increase breastfeeding opportunities for LPIs, educational programs for gestational age-appropriate breastfeeding should be developed. The focus of breastfeeding education needs to be on mothers who delivered their LPIs through Cesarean-section and LPIs who had feeding intolerance or were fed only formula during hospitalization.

BACKGROUND: We reported that level of lipopolysaccharide (LPS) exposure determined the type of airway inflammation in a murine model of asthma. OBJECTIVE: The purpose of this study is to evaluated the role of IL-13 in low dose LPS induced murine model of asthma using IL-13 and signal transducer and activator of transcription 6 (STAT6) deficient mice. METHODS: Mice were sensitized with an intranasal application of LPS-depleted ovalbumin (OA) and different doses of LPS (0.1 and 10 µg), and then challenged intranasally with OA alone. The phenotype changes between wild type (WT) and IL-13-/- mice and between WT and STAT6-/- mice were evaluated. RESULTS: We confirmed again that low and high dose LPS resulted in different phenotypes of murine asthma. In the present study, we observed that phenotypes of murine asthma induced by low dose LPS were abolished in the homozygous null mutation of the IL-13 and STAT6 gene. However, those changes were not shown in mice sensitized OA plus high dose LPS. CONCLUSION: IL-13 plays an important role in low dose LPS induced murine model of asthma. Our results provided a new insight in understanding of the potential role of IL-13 in innate immunity in human allergic asthma.

BACKGROUND AND OBJECTIVES: Arterial stiffness is well known as an important risk factor for cardiovascular disease. At our institution, we assessed the association between arterial stiffness, as determined by brachial ankle pulse wave velocity (baPWV), and the extent of coronary artery disease (CAD), as detected by conventional coronary angiography (CAG) in patients who visited the outpatient clinic for angina without any previous history of heart disease. In addition, we evaluated if the level of baPWV could predict the revascularization as a clinical outcome. SUBJECTS AND METHODS: On a retrospective basis, we analyzed the data of 651 consecutive patients who had undergone baPWV and elective CAG for suspected CAD between June 2010 and July 2011, at a single cardiovascular center. RESULTS: The baPWV was one of the statistically meaningful predictors of significant CAD (diameter of stenosis >50%) in addition to male gender, age, the level of high density lipoprotein-cholesterol, and hemoglobin A1c in multivariate analysis. However, baPWV was not the significant predictor of revascularization. When the extent of CAD was classified into following 4 groups; no significant CAD, 1-, 2- and 3-vessel disease, there was significant difference of baPWV between the significant and non-significant CAD group, but there was no difference of baPWV among the 3 significant CAD groups, although there was a trend toward the positive correlation. CONCLUSION: Although baPWV was an independent predictor of significant CAD, it was neither associated significantly with the extent of CAD nor with the risk of revascularization. Therefore, baPWV has a limited value for portending the severity of CAD in patients with chest pain.
