ABSTRACT
The personal protective equipment (PPE) used to minimize exposure to hazards can hinder healthcare workers from performing sophisticated procedures. We retrospectively reviewed 77,535 blood cultures (202,012 pairs) performed in 28,502 patients from January 2020 to April 2022. The contamination rate of all blood cultures was significantly elevated in the coronavirus disease 2019 ward at 4.68%, compared to intensive care units at 2.56%, emergency rooms at 1.13%, hematology wards at 1.08%, and general wards at 1.07% (All of P < 0.001). This finding implies that wearing PPE might interfere with adherence to the aseptic technique. Therefore, a new PPE policy is needed that considers the balance between protecting healthcare workers and medical practices.
ABSTRACT
Background@#Pretransfusion testing is vital for safe transfusion. However, in situations without time to perform sufficient testing, all or part of the pretransfusion testing may be skipped to issue blood quickly. This study evaluated the safety of red blood cell (RBC) transfusion released by an emergency blood transfusion protocol through retrospective analysis at a tertiary hospital for eight years. @*Methods@#All RBC transfusions following the emergency blood transfusion protocol from 2011 to 2018 at Seoul National University Hospital were included in the study. Crossmatching and unexpected antibody screening test results conducted after RBC release and the occurrence of hemolytic transfusion reactions were analyzed. @*Results@#A total of 1,541 cases (5,299 RBCs issued) of emergency blood transfusion were identified. RBCs were issued after performing the immediate spin crossmatch without an unexpected antibody screening test in most cases (1,443; 93.64%), while RBCs were issued with no pretransfusion testing in 98 cases (6.36%). Antibody screening tests performed after the issue of RBCs showed that 17 (1.1%) cases were positive. Two units of RBCs from two different cases showed positive antiglobulin crossmatch test results. However, none of them were suspected to be associated with a hemolytic transfusion reaction. @*Conclusion@#The incidence of incompatible RBC release was very low in patients receiving RBC transfusion through the emergency blood transfusion protocol suggesting it can be used safely with minimal risk of hemolytic transfusion reactions caused by incompatible blood transfusions.
ABSTRACT
Background@#In the coronavirus disease 2019 (COVID-19) pandemic era, the simultaneous detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), influenza virus (Flu), and respiratory syncytial virus (RSV) is important in the rapid differential diagnosis in patients with respiratory symptoms. Three multiplex real-time reverse transcription polymerase chain reaction (rRT-PCR) assays have been recently developed commercially in Korea: PowerChek™ SARS-CoV-2, Influenza A&B Multiplex Real-time PCR Kit (PowerChek; KogeneBiotech); STANDARD™ M Flu/SARS-CoV-2 Real-time Detection Kit (STANDARD M; SD BioSensor); and Allplex™ SARS-CoV-2/FluA/FluB/RSV Assay (Allplex; Seegene). We evaluated the analytical and clinical performances of these kits. @*Methods@#A limit of detection tests were performed and cross-reactivity analysis was executed using clinical respiratory samples. Ninety-seven SARS-CoV-2-positive, 201 SARS-CoV-2-negative, 71 influenza A-positive, 50 influenza B-positive, 78 RSV-positive, and 207 other respiratory virus-positive nasopharyngeal swabs were tested using the three assays. The AdvanSure™ respiratory viruses rRT-PCR assay (AdvanSure; LG Life Sciences) was used as a comparator assay for RSV. @*Results@#Except in influenza B, in SARS-CoV-2 and influenza A, there were no significant differences in detecting specific genes of the viruses among the three assays. All three kits did not cross-react with common respiratory viruses. All three kits had greater than 92% positive percent agreement and negative percent agreement and ≥ 0.95 kappa value in the detection of SARS-CoV-2 and flu A/B. Allplex detected RSV more sensitively than AdvanSure. @*Conclusion@#The overall performance of three multiplex rRT-PCR assays for the concurrent detection of SARS-CoV-2, influenza A/B, and RSV was comparable. These kits will promote prompt differential diagnosis of COVID-19, influenza, and RSV infection in the COVID-19 pandemic era.
ABSTRACT
Background@#Endobronchial ultrasound‒guided transbronchial needle aspiration (EBUS-TBNA) is a standard diagnostic method for mediastinal and hilar lymphadenopathy. Although rare, fatal infectious complications can occur following EBUS-TBNA. However, to date, there is a lack of effective preventive strategies to reduce these complications. We started a trial to investigate the effect of chlorhexidine mouthrinse on the prevention of microbial contamination during EBUS-TBNA. @*Methods@#This study is a single-center, parallel-group, assessor-blinded randomized controlled trial (RCT). We will enroll 112 adult participants undergoing EBUS-TBNA using a convex probe, and randomly assign them to two groups at a 1:1 ratio. The intervention group will gargle for 1 minute with 100 mL of 0.12% chlorhexidine gluconate before EBUS-TBNA, while the control group will have no mouthrinse before the procedure. Immediately after completion of EBUS-TBNA on all targeted lesions with an aspiration needle, a needle wash sample will be taken by instilling 5 mL of sterile saline into the used needle. The primary outcome is colony forming unit (CFU) counts in aerobic cultures of the needle wash samples. Secondary outcomes are CFU counts in anaerobic cultures, fever within 24 hours after EBUS-TBNA, and infectious complications within 4 weeks after EBUS-TBNA. @*Conclusion@#This trial was designed as the first RCT to investigate the effect of chlorhexidine mouthrinse on the prevention of microbial contamination during EBUS-TBNA. Results from this trial can provide clinical evidence for a simple, safe, and cost-effective strategy to prevent infectious complications following EBUS-TBNA (ClinicalTrials.gov ID: NCT04718922, registered on 22 January 2021).
ABSTRACT
Background@#Spinal cord injury (SCI) is a serious clinical condition that impacts a patient's physical, psychological, and socio-economic status. The aim of this pilot study was to evaluate the effects of training with a newly developed powered wearable exoskeleton (Hyundai Medical Exoskeleton [H-MEX]) on functional mobility, physiological health, and quality of life in non-ambulatory SCI patients. @*Methods@#Participants received 60 minutes of walking training with a powered exoskeleton 3 times per week for 10 weeks (total 30 sessions). The 6-minute walking test (6MWT) and timedup-and-go test (TUGT) were performed to assess ambulatory function. The physiological outcomes of interest after exoskeleton-assisted walking training were spasticity, pulmonary function, bone mineral density, colon transit time, and serum inflammatory markers. Effects of walking training on subjective outcomes were estimated by the Korean version of the Falls Efficacy Scale—International and the 36-Item Short-Form Health Survey version 2. @*Results@#Ten participants finished 30 sessions of training and could ambulate independently.No severe adverse events were reported during the study. After training, the mean distance walked in the 6MWT (49.13 m) was significantly enhanced compared with baseline (20.65 m). The results of the TUGT also indicated a statistically significant improvement in the times required to stand up, walk 3 m and sit down. Although not statistically significant, clinically meaningful changes in some secondary physiological outcomes and/or quality of life were reported in some participants. @*Conclusion@#In conclusion, this study demonstrated that the newly developed wearable exoskeleton, H-MEX is safe and feasible for non-ambulatory SCI patients, and may have potential to improve quality of life of patients by assisting bipedal ambulation. These results suggest that the H-MEX can be considered a beneficial device for chronic non-ambulatory SCI patients.

ABSTRACT
Background/Aims@#This study aimed to assess adherence to physical activity guidelines in cancer survivors and to investigate related factors. @*Methods@#The cross-sectional data of 39,845 community-dwelling participants aged ≥ 20 years (1,254 cancer survivors) in the Korea National Health and Nutrition Examination Survey were analyzed. The age- and sex-stratified prevalence for meeting exercise guidelines was obtained. The correlates of meeting exercise recommendations were evaluated by using complex-sample logistic regression models. @*Results@#Overall, 36.2% and 20.5% of cancer survivors met the recommendations for aerobic and resistance exercises, respectively. Cancer survivors and noncancer controls had similar low adherence to exercise recommendations in most age and sex groups, except young female cancer survivors (20 to 49 years old) who showed higher engagement in aerobic exercise than female noncancer controls in the same age group. Old cancer survivors (≥ 65 years) were less likely to engage in recommended levels of aerobic exercise than young cancer survivors (odds ratio [OR], 0.44; 95% confidence interval [CI], 0.24 to 0.79). Female cancer survivors were less likely to meet resistance exercise guidelines than male cancer survivors (OR, 0.32; 95% CI, 0.21 to 0.50). In addition, cancer survivors with current smoking status and cardiovascular disease were less likely to meet aerobic exercise recommendations. @*Conclusions@#The prevalence of meeting exercise guidelines are low in Korean cancer survivors and varied by age and sex. Old age is associated with an insufficient level of aerobic exercise, and female sex is associated with low participation in resistance exercise.
ABSTRACT
Histone deacetylase (HDAC) inhibitors represent a novel class of anticancer agents, which can be used to inhibit cell proliferation and induce apoptosis in several types of cancer cells. In this study, we investigated the anticancer activity of MHY4381, a newly synthesized HDAC inhibitor, against human prostate cancer cell lines and compared its efficacy with that of suberoylanilide hydroxamic acid (SAHA), a well-known HDAC inhibitor. We assessed cell viability, apoptosis, cell cycle regulation, and other biological effects in the prostate cancer cells. We also evaluated a possible mechanism of MHY4381 on the apoptotic cell death pathway. The IC50 value of MHY4381 was lower in DU145 cells (IC50=0.31 μM) than in LNCaP (IC50=0.85 μM) and PC-3 cells (IC50=5.23 μM). In addition, the IC50 values of MHY4381 measured in this assay were significantly lower than those of SAHA against prostate cancer cell lines. MHY4381 increased the levels of acetylated histones H3 and H4 and reduced the expression of HDAC proteins in the prostate cancer cell lines. MHY4381 increased G2/M phase arrest in DU145 cells, and G1 arrest in LNCaP cells. It also activated reactive oxygen species (ROS) generation, which induced apoptosis in the DU145 and LNCaP cells by increasing the ratio of Bax/Bcl-2 and releasing cytochrome c into the cytoplasm. Our results indicated that MHY4381 preferentially results in antitumor effects in DU145 and LNCaP cells via mitochondria-mediated apoptosis and ROS-facilitated cell death pathway, and therefore can be used as a promising prostate cancer therapeutic.
ABSTRACT
Objective@#To present new classification methods of knee osteoarthritis (KOA) using machine learning and compare its performance with conventional statistical methods as classification techniques using machine learning have recently been developed. @*Methods@#A total of 84 KOA patients and 97 normal participants were recruited. KOA patients were clustered into three groups according to the Kellgren-Lawrence (K-L) grading system. All subjects completed gait trials under the same experimental conditions. Machine learning-based classification using the support vector machine (SVM) classifier was performed to classify KOA patients and the severity of KOA. Logistic regression analysis was also performed to compare the results in classifying KOA patients with machine learning method. @*Results@#In the classification between KOA patients and normal subjects, the accuracy of classification was higher in machine learning method than in logistic regression analysis. In the classification of KOA severity, accuracy was enhanced through the feature selection process in the machine learning method. The most significant gait feature for classification was flexion and extension of the knee in the swing phase in the machine learning method. @*Conclusion@#The machine learning method is thought to be a new approach to complement conventional logistic regression analysis in the classification of KOA patients. It can be clinically used for diagnosis and gait correction of KOA patients.

ABSTRACT
PURPOSE: The dried body of Scolopendra subspinipes mutilans has long been used as a traditional Korean medicinal food, but little is known about its mechanisms of action. In this study, we investigated the anti-inflammatory activities of Scolopendra subspinipes mutilans and possible mechanisms in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. METHODS: Cytotoxicity of Scolopendra subspinipes mutilans extract (SSME) was measured by MTT assay, anti-inflammatory activities were analyzed by nitric oxide (NO) production, the expression of inducible NO synthase (iNOS) and the mRNA level of pro-inflammatory cytokines such as interleukin-1β (IL-1β) and interleukin-6 (IL-6). Nuclear translocation of nuclear factor-kappa B (NF-κB) p65 subunit and degradation of inhibitory kappa B (IκB) were examined by western blot. RESULTS: SSME inhibited LPS-induced NO production and iNOS expression without cytotoxicity. Up-regulation of LPS-induced pro-inflammatory cytokines, IL-1β and IL-6 was dose dependently attenuated by SSME. Exposure of pyrrolidine dithiocarbamate, an NF-κB specific inhibitor, accelerated the inhibitory effects of SSME on NO production and iNOS expression in LPS-stimulated cells. Moreover, translocation of NF-κB from the cytosol to the nucleus and degradation of IκB were decreased by treatment with SSME in LPS-induced cells. CONCLUSION: These results suggest that the SSME might have the inhibitory effects on inflammation, partly through inhibition of the NF-κB signaling pathway.

The Korean Society of Clinical Microbiology (KSCM) has supported participation in the European Society of Clinical Microbiology and Infectious Disease (ESCMID) Summer School for several years. The school is held every year in Europe for one week and in 2017 was held at the Borstel Research Center, located in Borstel, a small town near Hamburg, Germany. A total of 80 participants from 26 countries attended and included 42.5% (34) males, 57.5% (46) females, and most were residents. The summer school was held for 6 days except for moving time, and there were 29 lectures, 4 small group tutorials, and 80 student presentations. The lecture subject areas included overall topics of clinical microbiology and infectious diseases. Experts from all over Europe gave lectures explaining the basics as well as recent discoveries. Small group tutorials were mainly focused on tuberculosis. Student presentations included active discussions by the students regarding their research subjects or cases. There were also social events such as dinners, visiting museums, cruise ship excursions, and watching outdoor play. Based on personal experience, I recommend young KSCM members attend the ESCMID Summer School because communicating with people from various countries broadens horizons despite a long itinerary and a busy schedule.

PURPOSE: Neuroinflammation is mediated by activation of microglia implicated in the pathogenesis of neurodegenerative disorders such as Alzheimer's disease and Parkinson's disease. Inhibition of neuroinflammation may be an effective solution to treat these brain disorders. Petalonia binghamiae is known as a traditional food, based on multiple biological activities such as anti-oxidant and anti-obesity. In present study, the anti-neuroinflammatory potential of Petalonia binghamiae was investigated in LPS-stimulated BV2 microglial cells. METHODS: Cell viability was measured by MTT assay. Production of nitric oxide (NO) was examined using Griess reagent. Expression of inducible NO synthase (iNOS) and cyclooxygenase-2 (COX-2) was detected by Western blot analysis. Activation of nuclear factor κB (NF-κB) signaling was examined by nuclear translocation of NF-κB p65 subunit and phosphorylation of IκB. RESULTS: Extract of Petalonia binghamiae significantly inhibited LPS-stimulated NO production and iNOS/COX-2 protein expression in a dose-dependent manner without cytotoxicity. Pretreatment with Petalonia binghamiae suppressed LPS-induced NF-κB p65 nuclear translocation and phosphorylation of IκB. Co-treatment with Petalonia binghamiae and pyrrolidine duthiocarbamate (PDTC), an NF-κB inhibitor, reduced LPS-stimulated NO release compared to that in PB-treated or PDTC-treated cells. CONCLUSION: The present results indicate that extract of Petalonia binghamiae exerts anti-neuroinflammation activities, partly through inhibition of NF-κB signaling. These findings suggest that Petalonia binghamiae might have therapeutic potential in relation to neuroinflammation and neurodegenerative diseases.

BACKGROUND: Heparin-induced thrombocytopenia (HIT) is a significant complication of heparin therapy induced by antibodies to heparin/platelet factor 4 (PF4) complexes. We investigated the diagnostic performance of four commercial immunoassays that detect the anti-heparin/PF4 antibody. METHODS: Four different anti-heparin/PF4 antibody assays were performed in 39 patients with suspected HIT: HemosIL AcuStar HIT-IgG, HemosIL AcuStar HIT-total antibody (Ab) (Instrumentation Laboratory, USA), STic Expert HIT (Diagnostica Stago, France), and PF4 Enhanced (Immucor GTI Diagnostics, USA). Patients were diagnosed with HIT when the Chong score was > or =5. RESULTS: The estimated sensitivity and specificity for diagnosis of HIT were 33.3% and 80.0% for AcuStar HIT-IgG, 55.6% and 53.3% for AcuStar HIT-total Ab, 100.0% and 37.9% for STic Expert HIT, and 33.3% and 66.7% for PF4 Enhanced. All specificities significantly increased when 4Ts scores were included in the diagnosis. The areas under the curves (AUCs) for predicting thrombosis in the AcuStar HIT-IgG, AcuStar HIT-total Ab, and PF4 Enhanced assays were 0.639, 0.522, and 0.681, respectively. When the results of each assay were analysed along with 4Ts scores, the AUC increased to 0.927 in the AcuStar HIT-IgG assay and 0.944 in the AcuStar HIT-total Ab and PF4 Enhanced assays. CONCLUSIONS: The STic Expert HIT assay had high sensitivity but low specificity for diagnosis of HIT. The performances of the three other immunoassays were comparable to each other. Specificity significantly increased when assay data were combined with 4Ts scores. Differences in the diagnostic performance of the four immunoassays were not evident, and simultaneous consideration of clinical scoring systems improved performance.

OBJECTIVE: To compare fluid thickeners composed of starch polysaccharide (STA), guar gum-based polysaccharide (GUA), and xanthan gum-based polysaccharide (XAN) with the use of a viscometer and a line spread test (LST) under various measurement conditions. METHODS: The viscosity of thickened fluid with various concentrations (range, GUA 1%-4%, XAN 1%-6%, STA 1%-7%, at intervals of 1%) was measured with a rotational viscometer with various shear rates (1.29 s-1, 5.16 s-1, 51.6 s-1, and 103 s-1) at a temperature of 35degrees C, representing body temperature. The viscosity of STA showed time dependent alteration. So STA was excluded. Viscosities of GUA and XAN (range of concentration, GUA 1%-3%, XAN 1%-6%, at intervals of 1%) were measured at a room temperature of 20degrees C. LST was conducted to compare GUA and XAN (concentration, 1.5%, 2.0%, and 3.0%) at temperatures of 20degrees C and 35degrees C. RESULTS: The viscosities of 1% GUA and XAN were similar. However, viscosity differences between GUA and XAN were gradually larger as concentration increased. The shear thinning effect, the inverse relationship between the viscosity and the shear rate, was more predominant in XAN than in GUA. The results of LST were not substantially different from GUA and XAN, in spite of the difference in viscosity. However manufacturers' instructions do not demonstrate the rheological properties of thickeners. CONCLUSION: The viscosities of thickened fluid were different when the measurement conditions changed. Any single measurement might not be sufficient to determine comparable viscosity with different thickeners. Clinical decision for the use of a specific thickener seems to necessitate cautious consideration of results from a viscometer, LST, and an expert's opinion.

It can be difficult for clinicians to distinguish a paradoxical response to antituberculous therapy, worsening of an existing lesion despite adequate treatment, treatment failure, and drug resistance. We report a case of a 69-year-old woman who experienced bilateral lower extremity paralysis secondary to a paradoxical response. She had been suffering for 1 month from low back pain, due to tuberculous spondylitis. Her low back pain improved after antituberculous therapy. The low back pain, however, reappeared 2 months after treatment, accompanied by newly developed lower extremity weakness. Imaging studies showed an increased extent of her previous lesions. Consequently, the patient underwent a vertebral corpectomy with interbody fusion of the thoracolumbar spine. Histopathological examination showed chronic inflamed granulation tissue with no microorganisms. Although the antituberculous medication was not changed, the patient's symptoms and signs, including the paralysis, resolved after surgery.
