ABSTRACT
Objective@#This study aimed to evaluate whether somatic symptoms in adolescents with attention deficit hyperactivity disorder (ADHD) are associated with a dissociative pattern of functional connectivity (FC) within the default mode network (DMN) and whether methylphenidate administration can improve clinical and somatic symptoms. We also evaluated whether the improvement of somatic symptoms is associated with increased FC within the DMN in response to methylphenidate treatment. @*Methods@#Fifteen male adolescents with somatic symptoms of ADHD and 15 male adolescents with ADHD without somatic symptoms were included. At baseline and after 6 months of methylphenidate treatment, all adolescents were asked to complete questionnaires for the Korean version of the Dupaul’s ADHD rating scale, the symptom checklist-90-revised-somatization subscales, the Beck Depression Inventory, and the Beck Anxiety Inventory. Additionally, a resting-state functional magnetic resonance imaging scan was conducted. @*Results@#Methylphenidate treatment improved clinical and somatic symptoms in adolescents with ADHD. In addition, it increased brain FC within the DMN from the posterior cingulate cortex (posterior DMN) to the middle prefrontal cortex (anterior DMN). The improvement of somatic symptoms was associated with FC within the DMN from the posterior cingulate cortex to the middle prefrontal cortex in ADHD adolescents with somatic symptoms. @*Conclusion@#Methylphenidate increased brain FC between the anterior and posterior DMN. The improvement of somatic symptoms in adolescents with ADHD was associated with FC within the DMN. The DMN in adolescents with ADHD seems to be associated with the severity of the clinical and somatic symptoms of ADHD.
ABSTRACT
Objective@#The optimal imaging approach for evaluating pathological nipple discharge remains unclear. We investigated the value of adding ductography to ultrasound (US) for evaluating pathologic nipple discharge in patients with negative mammography findings. @*Materials and Methods@#From July 2003 to December 2018, 101 women (mean age, 46.3 ± 12.2 years; range, 23–75 years) with pathologic nipple discharge were evaluated using pre-ductography (initial) US, ductography, and post-ductography US. The imaging findings were reviewed retrospectively. The standard reference was surgery (70 patients) or > 2 years of followup with US (31 patients). The diagnostic performances of initial US, ductography, and post-ductography US for detecting malignancy were compared using the McNemar’s test or a generalized estimating equation. @*Results@#In total, 47 papillomas, 30 other benign lesions, seven high-risk lesions, and 17 malignant lesions were identified as underlying causes of pathologic nipple discharge. Only eight of the 17 malignancies were detected on the initial US, while the remaining nine malignancies were detected by ductography. Among the nine malignancies detected by ductography, eight were detected on post-ductography US and could be localized for US-guided intervention. The sensitivities of ductography (94.1% [16/17]) and post-ductography US (94.1% [16/17]) were significantly higher than those of initial US (47.1% [8/17]; p = 0.027 and 0.013, respectively). The negative predictive value of post-ductography US (96.9% [31/32]) was significantly higher than that of the initial US (83.3% [45/54]; p = 0.006). Specificity was significantly higher for initial US than for ductography and post-ductography US (p = 0.001 for all). @*Conclusion@#The combined use of ductography and US has a high sensitivity for detecting malignancy in patients with pathologic nipple discharge and negative mammography. Ductography findings enable lesion localization on second-look post-ductography US, thus facilitating the selection of optimal treatment plans.
ABSTRACT
Background@#Depression and cognitive function have a positive effect on the improvement of quality of life and extension of lifespan in the elderly. In addition, it appears as a major factor influencing oral health status. Therefore, this study looked at the relationship between the Geriatric Oral Health Assessment Index (GOHAI), depression, and cognitive function in the elderly using the Korea Longitudinal Study of Aging. @*Methods@#In this study, 4,535 elderly people aged 65 years and over were targeted using the 7th data of the 2018 Korea Longitudinal Study of Aging. A t-test and ANOVA analysis were performed to compare GOHAI, depression, and cognitive function by group. In addition, hierarchical multiple linear regression was performed to understand the effect of the elderly’s perceived depression scale and cognitive ability on GOHAI. @*Results@#As a result of adding the depression scale and cognitive function variables to Model 2, the explanatory power was 22%. Educational level, marital status, private health insurance subscription, average monthly allowance, subjective health status, use of dentures, smoking status, economic activity, depression scale, and cognitive function were found to have significant influence (p＜0.05). In addition, when controlled and viewed with all factors, depression and cognitive function were found to have an effect on oral health-related quality of life. @*Conclusion@#The findings indicate that depression and cognitive function are associated with oral health-related quality of life in the Korean elderly. As the age increases, the quality of life declines due to depression and cognitive function problems, in addition to oral discomfort, eating disorders, and physical discomfort.
ABSTRACT
Objective@#During the coronavirus disease (COVID-19) pandemic, several studies have found that Internet usage and gaming times have increased among adolescents. Parents’ Internet literacy and attitudes toward Internet gaming have been reported to affect children’s Internet gaming disorder (IGD). We hypothesized that parents’ attitudes toward Internet use and gaming would affect the prevalence of IGD among adolescents. @*Methods@#A total of 199 mothers of children who played Internet games were surveyed online to gather information regarding their demographic characteristics, children’s Internet use patterns, psychological factors, and Internet gaming literacy. @*Results@#Among adolescents, increased Internet usage or gaming time was not associated with IGD, but the presence of attention deficit hyperactivity disorder (ADHD) was. Among parents, anxiety, depression, and family togetherness were not related to IGD, but a positive perception of gaming protected against the development of IGD, whereas a negative perception was a risk factor for IGD. @*Conclusion@#Increased gaming time neither causes nor correlates with IGD in adolescents, even though ADHD may be a risk factor for IGD. Parents’ positive or negative perceptions of gaming can be protective or present a risk factor, respectively, for their children’s development of IGD.
ABSTRACT
BACKGROUND@#Autophagy plays important roles in odontogenic differentiation of dental pulp cells (DPCs) in the developmental stage of tooth bud. Few studies have reported the role of autophagy during reparative dentin formation process. The objective of this study was to discover gene expression pattern correlated to autophagy and their role during odontogenic differentiation process in DPCs. @*METHODS@#After tooth cavities were prepared on the mesial surface of lower first molar crown of rats. Odontogenic differentiation and reparative dentin formation were assessed based on detection of morphology change with hematoxylin and eosin staining. @*RESULTS@#After tooth cavities were prepared on the mesial surface of lower first molar crown of rats, odontogenic differentiation and reparative dentin formation were assessed based on detection of morphology change with hematoxylin and eosin staining and dentin sialophosphoprotein (DSPP), whereas autophagy inhibitor 3-methyladenine (3MA) reversed. @*Results@#of quantitative polymerized chain reaction array of autophagosome formation related genes revealed that GABARAPL2 was prominently upregulated while expression of other ATG8 family members were moderately increased after tooth cavity preparation. In addition, human DPCs incubated in differentiation medium predominantly upregulated MAP1LC3C, which selectively decreased by 3MA but not by autophagy enhancer trehalose. Knock-down of MAP1LC3C using shRNA resulted in strong downregulation of dentin matrix protein 1 and DSPP as well-known odontogenic marker compared to knock-down of MAP1LC3B during odontogenic differentiation process of human DPCs. @*CONCLUSION@#Our results suggest that MAP1LC3C plays a crucial role in odontogenic differentiation of human DPCs via regulating autophagic flux.
ABSTRACT
Purpose@#The purpose of this study was to develop a self-transcendence enhancement program and examine its effect on self-transcendence, spiritual well-being, and psychological well-being in elderly women who lived alone. @*Methods@#A self-transcendence enhancement program was developed through theory, literature review, and in-depth interviews. The theoretical framework came from the Psychoeducational Approach to Transcendence and Health intervention model based on Reed’s mid-range theory of self-transcendence. The program consisted of multiple modalities in a structured, theory-based program lasting for eight weekly sessions. Using a single-group pretest-posttest design, the program was tested on a group of 40 elderly women aged 75 to 84 years who lived alone in Daejeon, South Korea. Participants completed self-reported study questionnaires before and after the program at the elderly welfare center. Data were analyzed using SPSS version 24.0, with significance level set at .05. Paired t-test was used to compare mean differences before and after the program. @*Results@#The mean age of the study participants was 79.1 years. After completing the program, the participants showed higher levels of self-transcendence (t=8.78, p<.001), overall spiritual well-being (t=8.30, p=.002), religious spiritual well-being (t=1.79, p=.040), existential spiritual well-being (t=6.75, p=.002), and positive affect (t=3.77, p=.001) than they did before the program. They also reported lower levels of depression (t=–7.59, p<.001) and negative affect (t=–6.15, p<.001). @*Conclusion@#The self-transcendence enhancement program developed in this study may be effective for improving the level of self-transcendence in elderly women living alone and helping them to attain spiritual and psychological well-being.
ABSTRACT
Objective@#In somatic symptom disorder (SSD), cognitive dysfunction is related to perceptive distortion that excessively amplifies bodily sensations. The association between high body mass index (BMI) and cognitive dysfunction could be attributed to underlying systemic inflammation. We aimed to evaluate whether patients with SSD and high BMI exhibit increased somatic symptom severity and whether this is mediated by cognitive dysfunction. @*Methods@#This retrospective, cross-sectional study was conducted on 54 patients with SSD (20 males/34 females, mean age ± standard deviation: 40.65 ± 13.23 years). Participants’ BMI, laboratory data including complete blood count and lipid profile, results from the Korean Wechsler Adult Intelligence Scale-IV, and scores of the Korean-Symptom Checklist 95-Somatization (SCL95-SOM) were analyzed. We performed a path analysis to evaluate BMI as a predictor of somatic symptoms. @*Results@#In a path analysis, the SCL95-SOM score was directly influenced by working memory (b = −0.326, p = 0.032), which was significantly influenced by BMI (b = −0.338, p = 0.009), although there was no direct effect of BMI on the SCL95-SOM score. The path analytic model showed a close fit to the data with the following values: χ2 (df) = 0.918 (1), p = 0.338, root mean square error of approximation = 0.000 (＜ 0.001), and comparative fit index = 1.00. @*Conclusion@#Patients with SSD and high BMI may exhibit increased somatic symptom severity, and this is mediated by working memory dysfunction. Weight management may help improve symptoms in patients with SSD and high BMI.

ABSTRACT
Background@#The aim of this study was to analyze the public demand for information about the job of dental hygienists by mining text data collected from the online Q & A section on an Internet portal site. @*Methods@#Text data were collected from inquiries that were posted on the Naver Q & A section from January 2003 to July 2020 using “dental hygienist job recognition,” “role recognition,” “medical assistance,” and “scaling” as search keywords. Text mining techniques were used to identify significant Korean words and their frequency of occurrence. In addition, the association between words was analyzed. @*Results@#A total of 10,753 Korean words related to the job of dental hygienists were extracted from the text data. “Chi-lyo (treatment),” “chigwa (dental clinic),” “ske-illing (scaling),” “itmom (gum),” and “chia (tooth)” were the five most frequently used words. The words were classified into the following areas of job of the dental hygienist: periodontal disease treatment and prevention, medical assistance, patient care and consultation, and others. Among these areas, the number of words related to medical assistance was the largest, with sixty-six association rules found between the words, and “chi-lyo,” “chigwa,” and “ske-illing” as core words. @*Conclusion@#The public demand for information about the job of dental hygienists was mainly related to “chi-lyo,” “chigwa,” and “ske-illing” as core words, demonstrating that scaling is recognized by the public as the job of a dental hygienist. However, the high demand for information related to treatment and medical assistance in the context of dental hygienists indicates that the job of dental hygienists is recognized by the public as being more focused on medical assistance than preventive dental care that are provided with job autonomy.
ABSTRACT
Background@#This study examines the relationship between the emotional labor and compassion competence of clinical dental hygienists. It attempted to provide basic data to establish a plan to increase the dental hygiene performance of clinical dental hygienists in the future by identifying the factors influencing the dental hygiene work performance. @*Methods@#This study is aimed at clinical dental hygienists working at the Jeollabuk-do Dental Clinic from April to June 2020 by the Convenience Sampling Method. An online survey site program was used to explain the purpose and purpose of the study on social media including the dental hygienist community, and distribute a URL that allows you to participate in the survey only if you agree to the study. @*Results@#In emotional labor, there was a significant difference in job satisfaction and marital status, and in compassion competence, there were significant differences in job satisfaction, final education, and marital status by group. In dental hygiene work performance, compassion competency showed a statistically significant positive correlation. In other words, it was found that the higher the compassion competence, the higher the dental hygiene work performance. It was found that the total number of years worked and the compassion competence that influenced dental hygiene work performance were statistically significant. @*Conclusion@#In summary, in order to improve the dental hygiene work performance of clinical dental hygienists, it is necessary to compassion competence with the subject. To this end, it is believed that various supports, measures, and systematic management should be implemented to compassion competence of clinical dental hygienists.
ABSTRACT
Purpose@#This study aimed to predict a heavy nodal burden (≥3 metastatic axillary lymph nodes [LNs]) using axillary ultrasonography (US) and US-guided fine-needle aspiration biopsy (FNAB) in patients with early-stage breast cancer. @*Methods@#We retrospectively reviewed the medical records of 403 women (404 cancers) who underwent US-guided FNAB for axillary LN staging from January 2006 to December 2015. US findings and US-guided FNAB results were reviewed and compared using pathology results as the reference. Diagnostic performance was analyzed, and clinicopathological and radiological findings were compared between patients with <3 metastatic LNs and ≥3 metastatic LNs. @*Results@#The final pathology results revealed that 20.5% of cancers had heavy nodal metastases. US-guided FNAB showed significantly higher sensitivity (79.0% vs. 63.0%, P=0.009) and specificity (84.8% vs. 79.3%, P=0.036) in predicting heavy nodal metastases than did US. The presence of a larger number of suspicious LNs (two or more) on axillary US and positive FNAB results were significantly correlated with a heavy nodal burden in the multivariate analysis. The odds ratios were 4.20 (95% confidence interval [CI], 1.90 to 9.39) for two suspicious LNs, 9.40 (95% CI, 2.99 to 29.54) for three or more suspicious LNs, and 14.22 (95% CI, 6.78 to 29.82) for positive FNAB results. @*Conclusion@#The number of suspicious LNs detected on axillary US and FNAB results can help predict a heavy axillary nodal burden in patients with early-stage breast cancer.
ABSTRACT
Purpose@#The purpose of this study was to measure the cancer detection rate of computer-aided detection (CAD) software in preoperative automated breast ultrasonography (ABUS) of breast cancer patients and to determine the characteristics associated with false-negative outcomes. @*Methods@#A total of 129 index lesions (median size, 1.7 cm; interquartile range, 1.2 to 2.4 cm) from 129 consecutive patients (mean age±standard deviation, 53.4±11.8 years) who underwent preoperative ABUS from December 2017 to February 2018 were assessed. An index lesion was defined as a breast cancer confirmed by ultrasonography (US)-guided core needle biopsy. The detection rate of the index lesions, positive predictive value (PPV), and false-positive rate (FPR) of the CAD software were measured. Subgroup analysis was performed to identify clinical and US findings associated with false-negative outcomes. @*Results@#The detection rate of the CAD software was 0.84 (109 of 129; 95% confidence interval, 0.77 to 0.90). The PPV and FPR were 0.41 (221 of 544; 95% CI, 0.36 to 0.45) and 0.45 (174 of 387; 95% CI, 0.40 to 0.50), respectively. False-negative outcomes were more frequent in asymptomatic patients (P<0.001) and were associated with the following US findings: smaller size (P=0.001), depth in the posterior third (P=0.002), angular or indistinct margin (P<0.001), and absence of architectural distortion (P<0.001). @*Conclusion@#The CAD software showed a promising detection rate of breast cancer. However, radiologists should judge whether CAD software-marked lesions are true- or false-positive lesions, considering its low PPV and high FPR. Moreover, it would be helpful for radiologists to consider the characteristics associated with false-negative outcomes when reading ABUS with CAD.
ABSTRACT
Objective@#This study aims to empirically determine if indirect exposure to client violence has significant negative effects on social workers’ posttraumatic stress disorder (PTSD) the same way direct victimization does. @*Methods@#Using a sample of 1,359 social workers drawn from the data collected by the Seoul Association of Social Workers, this study employs descriptive statistics to examine the prevalence of indirect experiences with client violence, and utilizes a series of hierarchical regression analyses to demonstrate the potential impact of indirect exposure to client violence on PTSD. To assess the severity of PTSD symptoms in participants, the Korean version of the Impact of Events Scale-Revised (IES-R-K) was employed. @*Results@#A descriptive analysis shows that 12.4% of the sample indirectly experienced client violence by witnessing it or hearing about a violent incident, whereas 6.0% were directly victimized. Hierarchical regression analyses indicate that direct experience (B=4.548, p<0.05) and indirect experience (B=7.297, p<0.001) of client violence have a significant association with the scores on IES-R-K. An investigation of the interaction terms between experiences of client violence and violence-prevention training illustrates that such training significantly moderates the influence on the scores on IES-R-K from indirect exposure to client violence (B=-8.639, p<0.01). @*Conclusion@#Social workers who are indirectly exposed to client violence experience PTSD symptoms comparable to their colleagues who were directly victimized. Further, violence-prevention training has greater ameliorative effects with regard to indirect experience of client violence than for direct victimization.
ABSTRACT
Objectives@#：The purpose of this study was to find out how demographic factors, suicide attempt patterns, psychiatric history and management of suicide attempters affect the completion of emergency department (ED) based case management program. @*Methods@#：Among the patients who attempted suicide and visited the emergency department of Chung-Ang University Hospital from June 1, 2018 to May 31, 2021, 661 patients who agreed to case management were studied. After being discharged from the emergency department, subjects were registered for an eight-week follow-up service program. Hierarchical logistic regression analysis was conducted with demographic factors, suicide attempt patterns, psychiatric history and management as independent variables, and completion of case program as dependent variables. @*Results@#：Suicide attempt pattern had the most significant influence on the completion of case management program, followed by demographic factors, psychiatric history and management. Those who completed the case management program were significantly more likely to have suicide plans in the future, more authentic in sui-cide attempts, and had higher proportion of past suicide attempts than those who did not complete the program. @*Conclusions@#：To ensure that the subjects complete the follow-up project program and get connected to community services, an individualized approach with consideration of suicide attempt patterns, demographic factors, and psychiatric history is needed.
ABSTRACT
Background@#Owing to the increase in the aging population, the health problems of the elderly have become important social problems. Social support has a positive effect on improving the quality of life and prolonging the life of elderly people. It is one of the major factors that affects the oral health status of elderly people. The purpose of this study was to examine the relationship between oral health status and social support in elderly people using representative data. @*Methods@#In this study, data from a community health survey in 2015 involving 63,929 elderly people aged over 65 years were analyzed. T-test and ANOVA analyses were performed to compare the general characteristics of and perception about social support. Additionally, a linear regression analysis was performed to confirm the relationship between perceptions about social support and subjective oral health status. @*Results@#We found that sex, age, household income, education level, the presence of a spouse, existence of an unmet dental need, and regular oral check-up had a significant effect on subjective oral health status (p＜0.05). In addition, when controlled for all factors, social support has a significant impact on subjective oral health status. @*Conclusion@#The findings indicate that social support is associated with the subjective oral health status of Korean elderly. This suggests that community-level or government investment is required to improve the oral health of the elderly. In particular, policy interventions such as the establishment of facilities that promote social networks, especially facilities based on friendship networks, are needed.
ABSTRACT
Olfactory impairment occurs in patients with Alzheimer’s disease, and olfactory function tests are performed for the diagnosis of Alzheimer’s disease. However, the diagnosis and patient status are not currently outlined for vascular dementia, and many physicians do not consider concurrent vascular dementia in patients complaining of olfactory dysfunction. Here, we report a case of vascular dementia with no symptoms of dementia other than olfactory dysfunction. This case suggested that the olfactory function test is helpful not only for the diagnosis of Alzheimer’s disease but also for the early diagnosis of vascular dementia.
ABSTRACT
Objective@#We aimed to find the optimal cut-off scores for screening of odor detection threshold, odor discrimination, and odor identification tests for detection of mild cognitive impairment (MCI) and dementia in Korean elderly. @*Methods@#A total of 195 elderly people were divided into three groups: the normal cognition (NC), MCI, and dementia groups. All participants underwent neurocognitive and olfactory function tests. We used k-means cluster analysis and receiver operating characteristic (ROC) analysis to identify the most appropriate cut-off value. @*Results@#To distinguish the MCI from NC groups, odor identification [area under the curve (AUC)=0.670, p<0.007] with a cut-off point of 7 showed greater validity for screening (sensitivity/specificity=0.462/0.837) than did other olfactory function tests. To distinguish the MCI and dementia from NC as well, odor identification (AUC=0.817, p=0.002) with a cut-off point of 7 showed the highest validity for screening (0.785/0.654). To distinguish MCI from AD, an odor detection threshold (AUC=0.722, p=0.001) with a cut-off point of 2 showed the highest validity for screening (0.785/0.654). @*Conclusion@#Olfactory function tests may be a useful screening tool for cognitive decline before clinical symptoms of dementia have completely developed. This tool can be used as a supplementary tool to enhance the sensitivity of traditional cognitive tests to screen for dementia.
ABSTRACT
Objective@#Coping can be defined as the reactions to harm or distress individuals take to reduce stress. This study aimed to determine how an individual’s temperament and character is correlated with the person’s main coping method. @*Methods@#The Korean version of the Ways of Coping Questionnaire and Temperament and Character Inventory-Revised-Short Version were used to evaluate the coping strategies and temperament and character of 1,035 people. Four hierarchical linear regression analyses with the scores of each coping strategy subscale as a dependent variable were performed. @*Results@#High persistence, cooperativeness, self-transcendence, and low harm avoidance were associated with using a problem-focused coping strategy. Being female, high novelty seeking, reward dependence, and self-transcendence were associated with using a supportseeking coping strategy. High novelty seeking, self-transcendence, and low self-directedness were associated with using emotion-focused coping strategy. Being female, high novelty seeking, persistence, cooperativeness, and self-transcendence were associated with using a hopeful-thinking coping strategy. @*Conclusion@#Our results show that there may be specific personality features guiding what kind of coping strategy an individual might use in a given situation.
