A 62-year-old woman without vascular risk factors presented with left-sided weakness and numbness.
Magnetic resonance imaging (MRI) brain depicted acute right hemispheric infarcts in the cortical and
subcortical white matter. Initial MR angiography (MRA) showed large thrombus at the right carotid
bifurcation. Valvular atrial fibrillation (vAF) with severe tricuspid regurgitation (TR) was found on
two-dimensional echocardiography. Serial follow-up computed tomography angiography (CTA) or
MRA at 3, 9, and 15 days after anticoagulation alone showed complete resolution of the thrombus
with no neurological deterioration. Our case suggests that prompt institution of anticoagulantion alone
may result in radiologic resolution of the thrombus with improvement in patient’s clinical status.

Objective:
This study aimed to investigate the changes in interpersonal relationships, behavioral patterns, and emotional states of children and adolescents with psychiatric disorders and their caregivers immediately after the coronavirus disease of 2019 (COVID-19) outbreak in Daegu, South Korea.
Methods:
A total of 147 patients and 147 caregivers participated in the Survey for Outing and Time Usage for Child, Adolescent, and Parents and the COVID-19 Visual Analog Scale for Emotion. We classified the patients and their caregivers into the internalizing disorder (ID) and externalizing disorder (ED) groups and compared the changes.
Results:
Parent–child relationships for adolescent patients and caregivers were interrupted, and friend relationships in all participants were disrupted, while sibling relationships improved in adolescent patients. They experienced negative emotional changes. Time spent outdoor decreased and digital screen time increased for all participants. Friend and parent–child relationships were interrupted in the ED group compared to those in the ID group. ED patients experienced negative changes in emotional states, while ID patients showed no significant changes.
Conclusion
Results are meaningful as a reference for predicting changes in interpersonal relationships and mental status of pediatric psychiatric patients and for determining healthcare system adaptations to allow mental health support during the COVID-19 outbreak.

5.Current Status and Suggestions for the Improvement of Gross Anatomy Education in Dental Hygiene Program.
Korean Journal of Physical Anthropology 2015;28(3):167-174
Anatomy is an essential subject for dental hygienists. As such, in order to form academic systems for dental hygiene program, we cannot ignore research related to basic dental hygiene, which is related to the main competency of a dental hygienist. This research focused on the operation status of the curriculum related to gross anatomy of the head and neck led by the department of dental hygiene and was performed in order to propose a new direction regarding academics. This research analyzed the offering status of the anatomy curriculum using shared information, released by both the Association of Korean Dental Hygienist and the homepage website of the national dental hygiene, as a foundation. In addition, we conducted a survey of 21 (25.6%) professors out of 82 dental hygiene institutions in the nation. The fill-in survey was composed in order to obtain knowledge on each department's offering and operation system of the anatomy curriculum, general characteristics of professor and demand for the anatomy education. The SPSS 20.0 Program was used to analyze all of the materials with the exception of operation statuses of anatomic curriculums constructed via open questions. Nationally, the subject related to the gross anatomy was opened in Semester 2 during the first year 56.2% of the time, and the oral anatomy class recorded the highest percentage of 45.3%. The general trend of the professors who participated in this research was the highest recording of 85.0% for holders of dental hygiene license. Those who acquired doctoral degrees were found to be 17 individuals (85.0%) and 45.0% majored in health science. The operation methods of anatomic practices were revealed to be models, drawings, and audiovisuals while external practices failed to meet even the half-point of the study. The consensus opinion has indicated the need for a integrated education with clinical subjects, cadaver practices, developments of educational media, and standardization of anatomic terminology. Standardization of educational contents and systemization of practices are necessary for the improvement of anatomic studies of students studying dental hygiene. Cultivating anatomy specialists and sharing activities between academia are required for long-term development. We expect this research to contribute to overall quality improvement and the dental hygiene profession through the establishment of majors.

Annals of Clinical Microbiology 2016;19(1):1-6
BACKGROUND: Microbial screening tests of umbilical cord blood (UCB) are essential for stem cell transplantation. We analyzed the microbial contamination rate and distribution of isolated microorganisms over 10 years of samples from the MEDIPOST Cord Blood Bank. In addition, we studied the influence of inoculum volume microorganism culture and compared the yield and speed of microorganism detection. METHODS: Microbial screening tests were performed using a manual method, which includes using an inoculum of 2 mL of plasma, a byproduct of UCB processing from pediatric culture bottles. When positive blood culture was detected, each set was once again inoculated with 2 mL and 4 mL of plasma. RESULTS: From 2004 to 2013, a total of 133,610 UCB units were screened, of which 1,311 (0.9%) tested positive for contamination. The most frequently identified microorganism was Escherichia coli (34.6%), followed by Bacillus spp. (12.8%), Enterococcus faecalis (5.3%) and Klebsiella pneumoniae (4.4%). The total yield rate increased by 0.2% over this time period, although the yield rate of Bacillus spp. increased by 8.3%. CONCLUSION: The results of this study could be used in many ways with both domestic and international data regarding cord blood contamination. Also, other microbiology laboratories using culture conditions similar to ours could refer this study when preparing guidelines. Finally, by detecting low levels of bacteria, we have contributed to cord blood safety.

Journal of Nutrition and Health 2022;55(3):348-358
Purpose:
Hyperglycemia accelerates the formation of advanced glycation end products (AGEs), a group of compounds formed via non-enzymatic glycation/glycoxidation. Type 2 diabetes mellitus (T2DM) is related to oxidative stress, resulting in some overgeneration of AGEs. The accumulation of AGEs in T2DM patients leads to increased inflammation, DNA damage, tissue damage, progression of diabetic microvascular disease, and nephropathy. Heme oxygenase-1 (HO-1) is an intracellular enzyme that catalyzes the oxidation of heme. Expression of HO-1 in the endothelium and in muscle monocytes/macrophages was upregulated upon exposure to reactive oxygen species or oxidized low-density lipoprotein. Cells activated by oxidative stress are reported to release HO-1 in the serum. In the current study, we discuss the oxidative status according to the level of AGEs and the association of HO-1 with AGEs or urinary DNA damage marker in type 2 diabetic Korean patients.
Methods:
This study enrolled 36 diabetic patients. Subjects were classified into two groups by serum AGEs level (Low AGEs group: < 0.85 ng/mL serum AGEs; High AGEs group: > 0.85 ng/ mL serum AGEs). Body composition was measured using bioelectrical impedance analysis. Blood and urinary parameters were measured using commercial kits.
Results:
No significant differences were observed in the general characteristics and body composition between the two groups. Serum HO-1 concentration was significantly higher in the High AGEs group than in the Low AGEs group. After adjustment of age and gender, a correlation was performed to assess the association between serum HO-1 and serum AGEs or urinary 8-hydroxy-2′-deoxyguanosine (8-OHdG). Our results indicate that serum HO-1 is positively correlated with serum AGEs and urinary 8-OHdG.
Conclusion
Taken together, our results indicate that in diabetes patients, a high level of HO-1 is associated with a high concentration of AGEs and 8-OHdG, probably reflecting a protective response against oxidative stress.

Journal of Neurogastroenterology and Motility 2025;31(1):119-128
Background/Aims:
Serum gastrin levels may be elevated following proton pump inhibitor (PPI) therapy. We aim to elucidate the predictors for the development of hypergastrinemia in maintenance treatment for mild gastroesophageal reflux disease (GERD) using a half-dose PPI.
Methods:
This study analyzed data from a prospective randomized trial to compare continuous versus on-demand maintenance treatment modalities in patients with mild GERD. Age, sex, body mass index, Helicobacter pylori infection, serum gastrin levels, pepsinogen (PG) I/II ratios, total days of PPI intake, and weight-based PPI dosage (mg/kg) were evaluated.
Results:
Data from 293 patients who completed a randomized trial were analyzed (continuous group, n = 147 vs on-demand group, n = 146). In univariate analysis, age (P < 0.001), H. pylori infection (P = 0.012), baseline gastrin levels (P < 0.001), and baseline PG ratios (P = 0.016) significantly correlated with post-treatment gastrin levels. In multivariate analysis, age, baseline gastrin levels, and baseline PG ratios were independently associated with final serum gastrin levels. In univariate analysis, age (P = 0.018), H. pylori infection (P = 0.028), baseline gastrin levels (P = 0.011), and baseline PG ratios (P = 0.031) significantly correlated with the development of hypergastrinemia. In multivariate analysis, age, baseline gastrin levels, and baseline PG ratios were independently associated with the development of hypergastrinemia.
Conclusion
Old age, high baseline serum gastrin levels, and low baseline PG ratios are significant predictors of the development of hypergastrinemia in maintenance treatment for mild GERD using a half-dose PPI.
