RESUMO
Background@#Over the last decade, extracorporeal membrane oxygenation (ECMO) use in critically ill children has increased and is associated with favorable outcomes. Our study aims to evaluate the current status of pediatric ECMO in Korea, with a specific focus on its volume and changes in survival rates based on diagnostic indications. @*Methods@#This multicenter study retrospectively analyzed the indications and outcomes of pediatric ECMO over 10 years in patients at 14 hospitals in Korea from January 2012 to December 2021. Four diagnostic categories (neonatal respiratory, pediatric respiratory, postcardiotomy, and cardiac-medical) and trends were compared between periods 1 (2012–2016) and 2 (2017–2021). @*Results@#Overall, 1065 ECMO runs were performed on 1032 patients, with the annual number of cases remaining unchanged over the 10 years. ECMO was most frequently used for post-cardiotomy (42.4%), cardiac-medical (31.8%), pediatric respiratory (17.5%), and neonatal respiratory (8.2%) cases. A 3.7% increase and 6.1% decrease in pediatric respiratory and post-cardiotomy cases, respectively, were noted between periods 1 and 2.Among the four groups, the cardiac-medical group had the highest survival rate (51.2%), followed by the pediatric respiratory (46.4%), post-cardiotomy (36.5%), and neonatal respiratory (29.4%) groups. A consistent improvement was noted in patient survival over the 10 years, with a significant increase between the two periods from 38.2% to 47.1% (P = 0.004). Improvement in survival was evident in post-cardiotomy cases (30–45%, P = 0.002).Significant associations with mortality were observed in neonates, patients requiring dialysis, and those treated with extracorporeal cardiopulmonary resuscitation (P < 0.001). In pediatric respiratory ECMO, immunocompromised patients also showed a significant correlation with mortality (P < 0.001). @*Conclusion@#Pediatric ECMO demonstrated a steady increase in overall survival in Korea;however, further efforts are needed since the outcomes remain suboptimal compared with global outcomes.
RESUMO
Juvenile gangrenous vasculitis is characterized by the abrupt onset of scrotal ulcerations in young males, preceded by fever and pharyngeal symptoms. The etiology of this disease is poorly understood. The course is benign and self-limiting within a few weeks with no relapse. Because of its rare incidence, physicians often confuse it with Fournier’s gangrene, which progresses rapidly to severe systemic symptoms requiring urgent surgical intervention. Herein, we report a rare case of juvenile gangrenous vasculitis of the scrotum and emphasize the importance of awareness of this diagnosis to avoid unnecessary invasive surgical intervention. A 17-year-old boy presented with painful and tender, diffuse erythema and swelling with a necrotic lesion on the scrotum for three days. Preceding the cutaneous manifestations, he had a fever and sore throat. Physical examination showed an about 2 cmsized well-demarcated necrotic lesion on the anterior scrotum. Laboratory findings revealed neutrophilic leukocytosis with an elevated C-reactive protein and erythrocyte sedimentation rate. On scrotal ultrasonography, only edematous skin thickening and an increase in vascularity were observed. Histopathological examination showed epidermal necrosis and dermal neutrophilic infiltration. Empirical antibiotic treatment with ampicillin/sulbactam and clindamycin was administered and a prompt clinical resolution was observed.
RESUMO
Background@#For acute ischemic stroke (AIS) patients with history of prior stroke (PS) and diabetes mellitus (DM), intravenous recombinant tissue plasminogen activator (IV-tPA) therapy in the 3- to 4.5-hour window is off-label in Korea. This study aimed to assess the safety and efficacy of IV-tPA in these patients. @*Methods@#Using data from a prospective multicenter stroke registry between January 2009 and March 2021, we identified AIS patients who received IV-tPA in the 3- to 4.5-hour window, and compared the outcomes of symptomatic intracranial hemorrhage (SICH), 3-month mortality, 3-month modified Rankin Scale (mRS) score 0-1 and 3-month mRS distribution between patients with both PS and DM (PS/DM, n=56) versus those with neither PS nor DM, or with only one (non-PS/DM, n=927). @*Results@#The PS/DM group versus the non-PS/DM group was more likely to have a prior disability, hypertension, hyperlipidemia, coronary heart disease and less likely to have atrial fibrillation. The PS/DM and the non-PS/DM groups had comparable rates of SICH (0% vs. 1.7%; p>0.999) and 3-month mortality (10.7% vs. 10.2%; p=0.9112). The rate of 3-month mRS 0-1 was non-significantly lower in the PS/DM group than in the non-PS/DM group (30.4% vs. 40.7%; adjusted odds ratio [95% confidence interval], 0.81 [0.41-1.59]). @*Conclusions@#In the 3- to 4.5-hour window, AIS patients with PS/DM, as compared to those with non-PS/DM, might benefit less from IV-tPA. However, given the similar risks of SICH and mortality, IV-tPA in the late time window could be considered in patients with both PS and DM.
RESUMO
BACKGROUND/OBJECTIVES@#The prevalence of diabetes has continued to increase globally.Changes in eating habits, lack of exercise, increased stress, and aging are major contributors.Glycemic control is the key strategy of diabetes management. The purpose of this study was to analyze the utilization of nutrition labels and related factors among patients with diabetes.MATERIALS/METHODS: Data from the 7th Korea National Health and Nutrition Examination Survey were used. General, health-related, diabetes-related characteristics from 1,587 adults with diabetes history were included. Nutrition label utilization was assessed with awareness and use of nutrition labels and effects on food choice. For statistical analyses, chi-square test and multiple logistic regression analysis were performed. @*RESULTS@#The prevalence of awareness, use, and effects of nutrition labels on food choice among diabetic patients were 48.8%, 11.4%, and 9.6%, respectively. High monthly income, walking frequency, family history of diabetes, younger age at diagnosis, and shorter duration of diabetes were associated with higher nutrition label awareness. Nutrition label use and effect on food choice were higher in women, those with high monthly income, those diagnosed at younger than 45 yrs, those with diabetes for less than 10 yrs, those with meal therapy, or patients who had undergone a fundus examination. @*CONCLUSIONS@#Nutrition label utilization status was low in Korean patients with diabetes.Strategies are needed to promote nutrition label use as a diet management tool for patients with diabetes.
RESUMO
Background@#Ralstonia mannitolilytica is a causative organism of nosocomial infections, particularly associated with contaminated water, and resistant to various antibiotics, including carbapenems. Several clusters of R. mannitolilytica infections appeared in children at our institute from August 2018 to November 2019. @*Methods@#From March 2009 to March 2023, all patients admitted to Asan Medical Center Children’s Hospital in Seoul, Korea, with culture-confirmed R. mannitolilytica and corresponding clinical signs of infection were identified. Epidemiological and environmental investigations were conducted. Polymerase chain reaction (PCR) was performed for the genes of OXA-443 and OXA-444 on R. mannitolilytica isolates. @*Results@#A total of 18 patients with R. mannitolilytica infection were included in this study, with 94.4% (17/18) and 5.6% (1/18) being diagnosed with pneumonia and central line-associated bloodstream infection, respectively. All-cause 30-day mortality rate was 61.1% (11/18), and seven of the fatal cases were caused by R. mannitolilytica infection itself. The resistance rates to meropenem and imipenem werew 94.4% (17/18) and 5.6% (1/18), respectively. Although four out of nine meropenem-resistant R.mannitolilytica isolates had positive PCR results for OXA-443 and OXA-444 genes, there were no significant differences in antimicrobial susceptibility patterns. Environmental sampling identified R. mannitolylica at two sites: a cold-water tap of a water purifier and an exhalation circuit of a patient mechanical ventilator.After implementing and improving adherence to infection control policies, no additional R. mannitolilyticainfection cases have been reported since December 2019. @*Conclusion@#R. mannitolilytica can cause life-threatening infections with high mortality in fragile pediatric populations. To prevent outbreaks, healthcare workers should be aware of R. mannitolilytica infections and strive to comply with infection control policies.
RESUMO
Objective@#Dysphagia is a common clinical condition characterized by difficulty in swallowing. It is sub-classified into oropharyngeal dysphagia, which refers to problems in the mouth and pharynx, and esophageal dysphagia, which refers to problems in the esophageal body and esophagogastric junction. Dysphagia can have a significant negative impact one’s physical health and quality of life as its severity increases. Therefore, proper assessment and management of dysphagia are critical for improving swallowing function and preventing complications. Thus a guideline was developed to provide evidence-based recommendations for assessment and management in patients with dysphagia. @*Methods@#Nineteen key questions on dysphagia were developed. These questions dealt with various aspects of problems related to dysphagia, including assessment, management, and complications. A literature search for relevant articles was conducted using Pubmed, Embase, the Cochrane Library, and one domestic database of KoreaMed, until April 2021. The level of evidence and recommendation grade were established according to the Grading of Recommendation Assessment, Development and Evaluation methodology. @*Results@#Early screening and assessment of videofluoroscopic swallowing were recommended for assessing the presence of dysphagia. Therapeutic methods, such as tongue and pharyngeal muscle strengthening exercises and neuromuscular electrical stimulation with swallowing therapy, were effective in improving swallowing function and quality of life in patients with dysphagia. Nutritional intervention and an oral care program were also recommended. @*Conclusion@#This guideline presents recommendations for the assessment and management of patients with oropharyngeal dysphagia, including rehabilitative strategies.
RESUMO
Pancreatic pseudoaneurysm is a potentially life-threatening complication often associated with pancreatitis or pancreatic surgery. As the rupture of pancreatic pseudoaneurysms can lead to catastrophic bleeding and is associated with high mortality rates, clinical suspicion and early diagnosis are essential to improve patient outcomes. In the management of pseudoaneurysms, transarterial embolization (TAE) could be effective; however, there have been limited local studies on the outcomes of TAE for patients with pseudoaneurysm rupture associated with pancreatitis. Here, we describe patients who were diagnosed with pseudoaneruysm rupture associated with pancreatitis and treated with TAE.
RESUMO
Background/Aims@#Identification of Helicobacter pylori infection status is necessary as H. pylori is associated with gastric malignancy. Recently, a red linear scrape-like appearance on the gastric mucosa, called the “scratch sign,” was reported to be associated with H. pylori-negative gastric mucosal status. Herein, we aimed to validate the association between the scratch sign and H. pylori infection status. @*Methods@#The data of patients who underwent screening endoscopy at Bundang Jesaeng General Hospital between March 2023 and April 2023 were reviewed. Patients were classified as having an H. pylori current infection or non-infection status based on the results of rapid urease tests. Patients who had undergone H. pylori eradication therapy were excluded. Endoscopic features of the gastric mucosa were assessed using the Kyoto classification of gastritis. @*Results@#The scratch sign appeared more frequently in patients with non-infection than in those with current infection status (32.7% vs. 10.6%, respectively; P<0.001). Multivariate analysis showed that only the presence of sticky mucus was significantly associated with the presence of the scratch sign. Patient without the scratch sign had a higher prevalence of open-type atrophy, intestinal metaplasia, enlarged folds, and diffuse redness, which reflected a higher Kyoto score. @*Conclusions@#Presence of the gastric mucosal scratch sign, a novel endoscopic marker, is indicative of H. pylori-negative status and appears to be inversely correlated with the presence of sticky mucus. In addition to the Kyoto classification of gastritis, detection of the scratch sign may facilitate identification of the H. pylori infection status.
RESUMO
A reduced estimated glomerular filtration rate (eGFR) is a predictor for mortality in patients with acute myocardial infarction (AMI). This study aimed to compare mortality according to the GFR and eGFR calculation methods during long-term clinical follow-ups. Using the Korean Acute Myocardial Infarction Registry-National Institutes of Health Data, 13,021 patients with AMI were included in this study. Patients were divided into the surviving (n=11,503, 88.3%) and deceased (n=1,518, 11.7%) groups.Clinical characteristics, cardiovascular risk factors, and 3-year mortality-related factors were analyzed. eGFR was calculated using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) and Modification of Diet in Renal Disease (MDRD) equations. The surviving group was younger than the deceased group (62.6±12.4 vs. 73.6±10.5 years, p＜0.001), whereas the deceased group had higher hypertension and diabetes prevalences than the surviving group. A high Killip class was more frequently observed in the deceased group. eGFR was significantly lower in the deceased group (82.2±24.1 vs. 55.2±28.6 ml/min/1.73 m 2 , p＜0.001). Multivariate analysis revealed that low eGFR was an independent risk factor for mortality during the 3-year follow-up. The CKD-EPI equation was more useful for predicting mortality than the MDRD equation (0.766; 95% confidence interval [CI], 0.753-0.779 vs. 0.738; 95% CI, 0.724-0.753; p=0.001). Decreased renal function was a significant predictor of mortality after 3 years in patients with AMI. The CKD-EPI equation was more useful for predicting mortality than the MDRD equation.
RESUMO
Small bowel variceal bleeding is a rare cause of gastrointestinal hemorrhage, with clinical manifestations ranging from asymptomatic incidental findings to life-threatening conditions. The diagnosis and management of small bowel bleeding are challenging because of the localization of the lesion and the difficulty of the procedure. Trans-arterial embolization (TAE) is a secure and straightforward method for treating ectopic varices. On the other hand, there have been limited local studies on the outcomes of TAE for patients with small bowel variceal hemorrhage. This paper reports patients diagnosed with small bowel variceal bleeding and treated with TAE.
RESUMO
Purpose@#This study aimed to identify the relationships among disease severity, anxiety, depression, social support, unpleasant symptoms and self-care among patients with atrial fibrillation based on the unpleasant symptom theory, and to examine the mediating effects of unpleasant symptoms. @*Methods@#A cross-sectional study was conducted. The participants were 216 patients with atrial fibrillation who were being followed up on an outpatient basis at a university hospital in Seoul. Data were collected from November 1, 2020 to June 30, 2021, using self-report questionnaires. Data were analyzed using IBM SPSS/WIN 27.0 and PROCESS macro with 95% bias-corrected bootstrap confidence interval(CI). @*Results@#The average age of participants in this study was 66.0years. Disease severity (β=10.19,p<.001) and depression (β=1.53, p<.001) had significant positive relationships with unpleasant symptoms. Also, unpleasant symptoms (β=-0.03, p=.006) had a negative relationship with physical activity, which is a subscale of self- care. Social support (β=0.06, p<.001) was positively related with physical activity. Unpleasant symptoms showed a mediation effect in the relationship between disease severity and physical activity (Bias corrected bootstrap CI -0.65, -0.04). Depression had an indirect effect on physical activity that was mediated by unpleasant symptoms (Bias corrected bootstrap CI -0.11, -0.00). @*Conclusion@#The findings of this study suggest that integrated strategies including physical, psychological, and social factors should be considered to promote self-care in patients with atrial fibrillation.
RESUMO
Background@#Lateral collateral ligament injuries may occur in patients with chronic lateral epicondylitis. The present study aimed to compare the clinical outcomes of arthroscopic debridement between patients with chronic lateral epicondylitis combined with a partial ligament injury and those without a ligament injury. @*Methods@#Between 2016 and 2018, patients who underwent arthroscopic debridement for lateral epicondylitis were evaluated. Partial injury to the lateral collateral ligament was defined as discontinuity or thinning with increased signal of the lateral ligament on magnetic resonance imaging and laxity with a firm endpoint in the varus or posterolateral rotatory stress test. Arthroscopic debridement was performed when there was no apparent instability in the stress test under fluoroscopic guidance after anesthesia. Patients with a ligament injury were compared with those without a ligament injury in terms of physical examination (varus stress test and posterolateral rotatory drawer test), pain visual analog scale, Mayo elbow performance score, and quick disabilities of the arm, shoulder and hand score. @*Results@#There were 38 patients in the intact ligament group and 15 patients in the partial ligament injury group. There were 23 men and 30 women, and the mean patient age was 50 years (range, 27–77 years). The mean follow-up period was 30 months (range, 24–49 months). Instability was not observed in both groups at the last follow-up, and clinical scores improved significantly after surgery. Postoperative results did not show significant difference between the two groups. One patient in the partial injury group underwent revision open debridement owing to persistent pain. @*Conclusions@#The clinical outcomes of arthroscopic debridement for lateral epicondylitis did not show significant differences between patients with a partial ligament injury and those without a ligament injury.
RESUMO
Acute kidney injury (AKI) is a common complication in critically ill children. However, the common lack of baseline serum creatinine values affects AKI diagnosis and staging. Several approaches for estimating baseline creatinine values in those patients were evaluated. Methods: This single-center retrospective study enrolled pediatric patients with documented serum creatinine measurements within 3 months before admission and more than two serum creatinine measurements within 7 days after admission to the pediatric intensive care unit of a tertiary care children’s hospital between January 2016 and April 2020. Four different approaches for estimating AKI using serum creatinine measurements were compared: 1) back-calculation using age-adjusted normal reference glomerular filtration rates, 2) age-adjusted normal reference serum creatinine values, 3) minimum values measured within 7 days after admission, and 4) initial values upon admission. Results: The approach using minimum values showed the best agreement with the measured baseline value, with the largest intraclass correlation coefficient (0.623), smallest bias (–0.04), and narrowest limit of agreement interval (1.032). For AKI diagnosis and staging, the minimum values were 80.8% and 76.1% accurate, respectively. The other estimated baseline values underestimated AKI and showed poor agreement with baseline values before admission, with a misclassification rate of up to 42% (p < 0.001). Conclusion: Minimum values of serum creatinine measured within 7 days after hospital admission showed the best agreement with creatinine measured within 3 months before admission, indicating the possibility of using it as a baseline when baseline data are unavailable. Further large-scale studies are required to accurately diagnose AKI in critically ill children.
RESUMO
Collision tumors in which two different skin tumors appear in one lesion have often been reported. The cause of the collision tumor is not clearly known, but there is an opinion that it is a simple coincidence, and other authors assumed that one tumor will cause another. This rare but well-documented phenomenon often presents a diagnostic challenge to dermatologists due to its unusual and nonspecific presentation. We experienced a case of a 32-year-old woman who came to our hospital with a 1.5×1.5-cm-sized red-brown nodule with a surrounding brown patch on her right posterior shoulder that had been present since her childhood. Histologically, this lesion was thought to be a collision tumor with dermatofibroma and Ito nevus in the same lesion. No further treatment was done for this patient and a close follow-up is ongoing. Herein, we reported a first case of collision tumor with dermatofibroma and Ito nevus.
RESUMO
Background@#The phenotypic heterogeneity of psoriasis is suspected to reflect differences in its pathogenesis, but not yet completely elucidated. Studies of the Th1 and Th17 cytokines associated with different phenotypes of psoriasis have yielded inconsistent results. @*Objective@#To investigate the tissue expression levels of Th1 and Th17 cytokines among patients with chronic plaque psoriasis, acute guttate psoriasis, and healthy control. @*Methods@#A total of 20 patients with psoriasis (10 with chronic plaque type and 10 with acute guttate type) and 5 healthy controls were enrolled. The tissue mRNA and protein levels of following cytokines were measured: interleukin (IL)-12, IL-2, interferon (IFN)-γ, IL-23, IL-17A, and IL-22. @*Results@#The tissue mRNA levels of IL-12, IFN-γ, IL-23, IL-17A, IL-22 and the protein levels of IL-12, IL-2, IFN-γ, IL-17A, IL-22 were significantly increased in the psoriasis patients compared with the healthy controls. In comparisons of the subtypes, the tissue mRNA level of IFN-γ was increased in acute guttate psoriasis, whereas the protein levels of IL-12 and IL-17A were significantly increased in chronic plaque psoriasis. The cytokine ratios of IL-17A/IL-2 and IL-22/IL-2 were significantly higher in chronic plaque psoriasis than in acute guttate psoriasis. @*Conclusion@#We confirmed that the tissue levels of Th1 and Th17 cytokines were increased in psoriasis patients compared with healthy controls. The increased IFN-γ mRNA level in acute guttate psoriasis and increased IL-12 and IL-17A protein levels in chronic plaque psoriasis suggest that an imbalance between Th1 and Th17 cytokines may play a role in the phenotypic transition of psoriasis.
RESUMO
Objectives@#Mucous retention cysts and pseudoantral cysts are mainly located within the floor of the maxillary sinus. Most of these maxillary cysts are asymptomatic and often only require observation. However, the presence of these benign maxillary cysts may create problems when maxillary sinus all types of implants are needed. Various treatment methods have been introduced. The selected treatment option depends on the type, size, and location of the cyst and its symptoms. @*Patients and Methods@#The case reports of four patients with maxillary cysts were reviewed retrospectively. These patients received a sinus lift between January 2016 and October 2021 at the Wonkwang University Dental Hospital. @*Results@#To reduce unnecessary operations and the duration of treatment, a conservative treatment method is required. A sinus lift in the presence of maxillary cyst will not typically cause sinus problems if the lifted sinus membrane does not interfere with ventilation of the maxillary sinus. @*Conclusion@#When proper treatment is provided, sinus perforation during a sinus lift performed in the presence of maxillary cyst and contamination of bone graft materials by cystic fluid does not necessarily result in adverse outcomes.
RESUMO
Angelica tenuissima Nakai (ATN) is an herbal medicine used to treat toothache, headaches, and cold symptoms. However, the therapeutic effects of ATN have not been thoroughly identified. The purpose of this research was to explore the effect of ATN in osteo/odontoblastic differentiation of human periodontal ligament stem cells (hPDLSCs). The influences of ATN on the differentiation and proliferation of hPDLSCs were evaluated using alizarin red S staining, real-time PCR, western blot and MTT assay. ATN promoted osteo/odontoblastic differentiation of hPDLSCs, accelerated mineral nodule formation in vitro, and displayed no toxicity at higher concentrations. The mRNA expression levels of alkaline phosphatase (ALP), type I collagen (COL1), osteopontin (OPN), dentin matrix acidic phosphoprotein 1 (DMP-1), and dentin sialophosphoprotein (DSPP) in hPDLSCs and the protein levels of osteocalcin (OCN), DSPP, DMP-1, and Runx2 were significantly higher after ATN treatment. HEK293 cells overexpressing the osterix (OSX) gene and treated with ATN (100 µg/mL) showed an increase in BSP promoter activity.Those results suggest that ATN enhances the osteo/odontoblastic differentiation of hPDLSCs. These therapeutic properties of ATN can serve as a theoretical basis for further research on the applicability of ATN in periodontal tissue regeneration.
RESUMO
Background@#This study was conducted to investigate factors related to unmet medical needs of medical care in adult diabetes patients and to suggest factors related to unmet medical in Korea. @*Methods@#This study used data from the Korea National Health and Nutrition Examination Survey (KNHNES) 2014–2017. The subjects of the study were conducted on patients with unmet medical needs experience among the patients and analyzed using the IBM SPSS ver. 25.0 program (IBM Corp., Armonk, NY, USA). @*Results@#Overall, 10.9% of patients had unmet medical needs. Being female, less educated, and lower medical aid were related to unmet medical needs. And subjects with poor subjective health and higher stress level were more likely to report unmet medical needs. @*Conclusion@#Although comprehensive health insurance coverage, 10.9% of people with diabetes experienced unmet healthcare needs. The results of this study suggest that socioeconomic factors such as low education and medical aid were associated with unmet medical needs.
RESUMO
Objectives@#The purpose of this study is to investigate the effects of social capital characteristics, socio-demographic characteristics, physical condition, and health behavior characteristics on health-related quality of life of the elderly in Korea. @*Methods@#T-test, one-way ANOVA, and regression analysis were performed by applying a complex sample design to 57.787 people aged 65 and over using the 2019 Community Health Survey. @*Results@#First, as a result of complex-sample T-test and ANOVA analysis, it was found that there were differences in health-related quality of life according to social capital characteristics, physical condition & health behavior characteristics, and socio-demographic characteristics. Complex Sample Regression Analysis Results, the explanatory power of the model was 28%. When living in the metropolitan area, living in an apartment building, having a spouse, having a higher household income, economic activity, higher educational attainment, increase sleeping time, walking time, frequent binge drinking, health checkup, networking, trust, and social participation showed higher health-related quality of life. When people were older, their gender was female, higher BMI, number of chronic diseases, and severe stress that showed lower health-related quality of life. @*Conclusions@#It was proved that the factors affecting the health-related quality of life of the elderly are not only physical condition and health behavior factors, but also social capital and socio-demographic characteristics.It was found that the role as a member was important.
RESUMO
Objectives@#This study examined the current status of depression and related factors among children using community child center. @*Methods@#A cross-sectional study selected children in grades 4-6 who used the Gwangju and Jeollanamdo community child center (n=224) using a convenience sampling method. General characteristics, family characteristics, children's emotional characteristics, children's school life environment and depression status were assessed using a self-reported questionnaire. @*Results@#The average score of depression among children using community child center was 15.31±7.70 out of a total of 27. Fifty-eight (25.9%) children had depression above 22 points. Variables related to children's depression were shown as grade, subjective economic level awareness, after-school activities excluding local children's centers, presence of family members after school, and family structure. @*Conclusions@#The depression prevalence of children using community child center was higher. Policy support such as children's psychological support programs would be needed to reduce children's depression, and community child centers are expected to be effective in reducing children's depression if continuous child psychological support services are developed for children's mental health.
