Background:
We aimed to analyze the effects of an antimicrobial stewardship program (ASP) on the proportion of antimicrobial-resistant pathogens in bacteremia, antimicrobial use, and mortality in pediatric patients.
Methods:
A retrospective single-center study was performed on pediatric inpatients under 19 years old who received systemic antimicrobial treatment from 2001 to 2019. A pediatric infectious disease attending physician started ASP in January 2008. The study period was divided into the pre-intervention (2001–2008) and the post-intervention (2009–2019) periods. The amount of antimicrobial use was defined as days of therapy per 1,000 patientdays, and the differences were compared using delta slope (= changes in slopes) between the two study periods by an interrupted time-series analysis. The proportion of resistant pathogens and the 30-day overall mortality rate were analyzed by the χ2 .
Results:
The proportion of extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli and Klebsiella pneumoniae bacteremia increased from 17% (39 of 235) in the pre-intervention period to 35% (189 of 533) in the post-intervention period (P < 0.001). The total amount of antimicrobial use significantly decreased after the introduction of ASP (delta slope value = −16.5; 95% confidence interval [CI], −30.6 to −2.3; P = 0.049). The 30-day overall mortality rate in patients with bacteremia did not increase, being 10% (55 of 564) in the pre-intervention and 10% (94 of 941) in the post-intervention period (P = 0.881).
Conclusion
The introduction of ASP for pediatric patients reduced the delta slope of the total antimicrobial use without increasing the mortality rate despite an increased incidence of ESBL-producing gram-negative bacteremia.

Background:
Paradoxical responses (PR) occur more frequently in lymph node tuberculosis (LNTB) than in pulmonary tuberculosis and present difficulties in differential diagnosis of drug resistance, new infection, poor patient compliance, and adverse drug reactions. Although diagnosis of mediastinal LNTB has become much easier with the development of endosonography, limited information is available. The aim of this study was to investigate the clinical course of mediastinal LNTB and the risk factors associated with PR.
Methods:
Patients diagnosed with mediastinal LNTB via endosonography were evaluated retrospectively between October 2009 and December 2019. Multivariable logistic regression was applied to evaluate the risk factors associated with PR.
Results:
Of 9,052 patients who underwent endosonography during the study period, 158 were diagnosed with mediastinal LNTB. Of these, 55 (35%) and 41 (26%) concurrently had pulmonary tuberculosis and extrapulmonary tuberculosis other than mediastinal LNTB, respectively. Of 125 patients who completed anti-tuberculosis treatment, 21 (17%) developed PR at a median of 4.4 months after initiation of anti-tuberculosis treatment. The median duration of anti-tuberculosis treatment was 6.3 and 10.4 months in patients without and with PR, respectively. Development of PR was independently associated with age < 55 years (adjusted odds ratio [aOR], 5.72; 95% confidence interval [CI], 1.81–18.14; P = 0.003), lymphocyte count < 800/μL (aOR, 8.59; 95% CI, 1.60–46.20; P = 0.012), and short axis diameter of the largest lymph node (LN) ≥ 16 mm (aOR, 5.22; 95% CI, 1.70–16.00; P = 0.004) at the time of diagnosis of mediastinal LNTB.
Conclusion
As PR occurred in one of six patients with mediastinal LNTB during antituberculosis treatment, physicians should pay attention to patients with risk factors (younger age, lymphocytopenia, and larger LN) at the time of diagnosis.

Objective:
This study compared the treatment results of emergency department (ED) patients presenting with gingival bleeding, who were given dental consultations with those who were not. Also, the study compared patients presenting with gingival bleeding based on the period of availability of the dental consultation in the ED.
Methods:
This was a retrospective study of patients with gingival bleeding visiting the ED from January 2011 to April 2020. The demographic data of patients, past medical history, etiology of bleeding, vital signs, lab findings, treatment methods, and disposition were analyzed.
Results:
The mean level of hemoglobin was 13.3 g/dL in the group to whom dental consultation was made available, and 11.7 g/dL in the group not given dental consultation, which was a significant difference (P=0.010). Vitamin K injections were given to 1.9% of the former group and 6.2% of the latter group (P=0.049). Suturing was done in 14% of the former group and 1.2% of the latter (P<0.001). There were no significant differences between the two groups regarding admission to the ward or revisits to the ED.
Conclusion
Emergency physicians carried out conservative treatments for patients with gingival bleeding when dental consultation was unavailable. No differences in the treatment results were observed based on the length of time the dental consultation was made available.

Purpose:
Various hemostatic agents have been introduced in therapy as postoperative bleeding is a poor prognostic factor for postoperative outcomes. These products can be divided into those that directly promote the hemostatic cascade and those that physically form a barrier by absorbing blood. The latter, powder-type hemostatic agents have the advantages of being inexpensive and more absorbable with less foreign body reactions (FBRs) and are applicable to a relatively wide area. This study was conducted to verify the safety and efficacy of a newly invented polysaccharide product (OOZFIX, Theracion Biomedical), which improves blood absorption and hemostatic effects.
Methods:
Two separate animal experiments were performed. The first evaluated FBRs histologically at 3 days, 2 weeks, and 4 weeks, after implantation of OOZFIX in rats, and the second compared hemostatic performance of OOZFIX and Arista AH (Bard) in the porcine liver punch biopsy model.
Results:
We found minimal FBRs in the 3-day group and no reactions in both the 2-week and 4-week groups after implantation of hemostatic agents. The time to hemostasis of OOZFIX was not significantly different from that of Arista AH (median [interquartile range]: 9 [6–10] minutes vs. 8 [6–10] minutes, respectively; P = 0.522). When comparing the serial bleeding grade tendency, there was no statistical difference between OOZFIX and Arista AH (P = 0.656).
Conclusion
OOZFIX caused a minimal FBR that disappeared within 2 weeks in vivo, and its hemostatic performance was comparable with that of an existing agent, Arista AH. Further clinical studies are required in the future.

Purpose:
Diagnostic biomarkers of pancreatic ductal adenocarcinoma (PDAC) have been used for early detection to reduce its dismal survival rate. However, clinically feasible biomarkers are still rare. Therefore, in this study, we developed an automated multi-marker enzyme-linked immunosorbent assay (ELISA) kit using 3 biomarkers (leucine-rich alpha-2-glycoprotein [LRG1], transthyretin [TTR], and CA 19-9) that were previously discovered and proposed a diagnostic model for PDAC based on this kit for clinical usage.
Methods:
Individual LRG1, TTR, and CA 19-9 panels were combined into a single automated ELISA panel and tested on 728 plasma samples, including PDAC (n = 381) and normal samples (n = 347). The consistency between individual panels of 3 biomarkers and the automated multi-panel ELISA kit were accessed by correlation. The diagnostic model was developed using logistic regression according to the automated ELISA kit to predict the risk of pancreatic cancer (high-, intermediate-, and low-risk groups).
Results:
The Pearson correlation coefficient of predicted values between the triple-marker automated ELISA panel and the former individual ELISA was 0.865. The proposed model provided reliable prediction results with a positive predictive value of 92.05%, negative predictive value of 90.69%, specificity of 90.69%, and sensitivity of 92.05%, which all simultaneously exceed 90% cutoff value.
Conclusion
This diagnostic model based on the triple ELISA kit showed better diagnostic performance than previous markers for PDAC. In the future, it needs external validation to be used in the clinic.
6.A Simulation-Based Empathy Enhancement Program for Non-Medical Care Providers of Older Adults: A Mixed-Methods Study
Psychiatry Investigation 2021;18(2):132-139
Objective:
Studies using simulation-based programs for empathy enhancement have been conducted mostly for health profession students and medical care providers in Western countries. No empirical research has been conducted for non-medical care providers of older adults in community settings in Asian countries. The purposes of this mixed-methods study were: to explore experiences and perceived usability of non-medical care providers of older adults in a simulation-based empathy enhancement program; and to examine if the program is effective in improving empathy and relevant outcomes.
Methods:
104 non-medical care providers of older adults in South Korea participated in a simulation-based empathy enhancement program in 2018. Data were collected using self-reported questionnaires for effectiveness testing, a program evaluation questionnaire, and individual interviews and analyzed using statistical tests and thematic analysis.
Results:
Care providers showed higher levels of empathy and lower levels of stress and burnout after the program participation (p<0.05). Qualitative findings supported the improved attitude and care strategies, increased empathy towards older adults, preparing for their own aging, and restoration of emotional stability through the participation in the program.
Conclusion
This study suggests that the simulation-based program is useful in promoting empathic responses of non-medical care providers working with older adults.

OBJECTIVE: Dysphagia is a major complication of stroke and causes serious problems, such as lung aspiration. Previous reviews of dysphagia treatments for stroke were limited due to a dearth of available studies. More trials have been published recently warranting a re-examination of the evidence. The purpose of this systematic review was to examine the effectiveness of interventions for dysphagia in adults following stroke. METHODS: The PRISMA Statement with a 27-item checklist was used as a general guide to conduct and report a quality systematic review. Five electronic databases were searched for randomized controlled trials published in English between 2008 and 2017 examining the effectiveness of dysphagia interventions following stroke. The search terms were entered by combining the keywords related to dysphagia, stroke, interventions, and randomized controlled trials. RESULTS: Fifteen articles were included; the most commonly used interventions were Transcranial Magnetic Stimulation (4 articles), Neuromuscular Electrical Stimulation (4 articles), and Pharyngeal electrical stimulation (4 articles). CONCLUSION: This review provides evidence of the effectiveness of interventions for people with dysphagia following stroke, but there were some mixed results. The heterogeneity of the outcome measures as well as the mixed results highlight the need for further research.

The purpose of the present study was to examine the severity of suicidal ideation of the older adults according to the amount of involvement in grandchild care. Data for this research were drawn from a cross-sectional study conducted on community-dwelling adults aged 65 years or older. The 922 participants were divided into three groups according to their involvement in grandchild care: 18.5% had provided daily care, 12.4% had provided occasional care, and 69.1% had never cared for their grandchildren. ANCOVA analysis showed that the scores for depression was significantly lower in the group which took care of their grandchildren occasionally compared to the other two groups. The scores for suicidal ideation was significantly higher in the group which had never taken care of their grandchildren compared to the other two groups. Current study suggests that grandparenting may have a positive effect on suicidal ideation of the older adults.
