ABSTRACT

BACKGROUND@#The extracellular matrix (ECM) has many functions, such as segregating tissues, providing support, and regulating intercellular communication. Cartilage-derived ECM (CECM) can be prepared via consecutive processes of chemical decellularization and enzyme treatment. The purpose of this study was to improve and treat osteoarthritis (OA) using porcine knee articular CECM. @*METHODS@#We assessed the rheological characteristics and pH of CECM solutions. Furthermore, we determined the effects of CECM on cell proliferation and cytotoxicity in the chondrocytes of New Zealand rabbits. The inhibitory effect of CECM on tumor necrosis factor (TNF)-a-induced cellular apoptosis was assessed using New Zealand rabbit chondrocytes and human synoviocytes. Finally, we examined the in vivo effects of CECM on inflammation control and cartilage degradation in an experimental OA-induced rat model. The rat model of OA was established by injecting monosodium iodoacetate into the intra-articular knee joint. The rats were then injected with CECM solution. Inflammation control and cartilage degradation were assessed by measuring the serum levels of proinflammatory cytokines and C-telopeptide of type II collagen and performing a histomorphological analysis. @*RESULTS@#CECM was found to be biocompatible and non-immunogenic, and could improve cell proliferation without inducing a toxic reaction. CECM significantly reduced cellular apoptosis due to TNF-a, significantly improved the survival of cells in inflammatory environments, and exerted anti-inflammatory effects. @*CONCLUSION@#Our findings suggest that CECM is an appropriate injectable material that mediates OA-induced inflammation.

ABSTRACT

The subscapularis tendon is the largest and most powerful muscle in the rotator cuff, playing a more important role in raising the arm than the supraspinatus or infraspinatus tendon. Subscapularis tendon tears are uncommon, but when it does occur, symptoms are often minimal and diagnosis can be delayed until severe atrophy occurs, leading to weakness of the shoulder muscles. Therefore, early diagnosis and surgical repair of suspected subscapularis tendon injury in athletes is very important for achieving the best functional outcome. Shoulder injuries in professional boxers have been reported to account for only about 3% of all boxing injuries, but there is no specific research on the specific location of these injuries. In this study, the authors report on a case of isolated subscapularis tendon injury that occurred during sparring in a professional boxer and discuss the mechanism of injury and treatment outcomes along with a review of the literature.

ABSTRACT

Serious acupuncture-related complications are rare in infants. We experienced a case of a 58-day-old infant with an umbilical hernia who received acupuncture from a non-professional guardian. Upon initial examination in the emergency department, the omentum protruded through the skin defect caused by acupuncture performed on top of the hernia. The infant underwent emergency surgery, and subsequently recovered uneventfully.

ABSTRACT

Background@#and Purpose Moderate-intensity statin plus ezetimibe versus high-intensity statin alone may provide a greater low-density lipoprotein cholesterol (LDL-C) reduction in patients with recent ischemic stroke. @*Methods@#This randomized, open-label, controlled trial assigned patients with recent ischemic stroke <90 days to rosuvastatin/ezetimibe 10/10 mg once daily (ROS10/EZT10) or to rosuvastatin 20 mg once daily (ROS20). The primary endpoint was LDL-C reduction ≥50% from baseline at 90 days. Key secondary endpoints were LDL-C <70 mg/dL and multiple lipid goal achievement, and composite of major vascular events. @*Results@#Of 584 randomized, 530 were included in the modified intention-to-treat analysis. The baseline LDL-C level was 130.2±34.7 mg/dL in the ROS10/EZT10 group and 131.0±33.9 mg/dL in the ROS20 group. The primary endpoint was achieved in 198 patients (72.5%) in the ROS10/EZT10 group and 148 (57.6%) in the ROS20 group (odds ratio [95% confidence interval], 1.944 [1.352–2.795]; P= 0.0003). LDL-C level <70 mg/dL was achieved in 80.2% and 65.4% in the ROS10/EZT10 and ROS20 groups (P=0.0001). Multiple lipid goal achievement rate was 71.1% and 53.7% in the ROS10/EZT10 and ROS20 groups (P<0.0001). Major vascular events occurred in 1 patient in the ROS10/EZT10 group and 9 in the ROS20 group (P=0.0091). The adverse event rates did not differ between the two groups. @*Conclusion@#Moderate-intensity rosuvastatin plus ezetimibe was superior to high-intensity rosuvastatin alone for intensive LDL-C reduction in patients with recent ischemic stroke. With the combination therapy, more than 70% of patients achieved LDL-C reduction ≥50% and 80% had an LDL-C <70 mg/dL at 90 days.

ABSTRACT

Methods@#We used 1.0-mm interval computed tomographic scan images of 100 patients (50 men and 50 women) and screw trajectory simulation software. The diameter of all screws was set at 3.5 mm, considering its common usage in real surgery. The anatomical feasibility of placing both pedicle and laminar screws on the same side was evaluated. For all feasible sides, the three-dimensional distance between the screw entry points was measured. @*Results@#In 85% of cases, both pedicle and laminar screws could be placed on both sides, allowing for the insertion of 4 screws. In 11% of cases, 2 screws could be placed on one side, while only 1 screw was feasible on the other side, resulting in the placement of 3 screws. In all 181 sides where both types of screws could be inserted, the distance between their entry points exceeded 16.1 mm, which was sufficient to prevent the collision between the screw heads. @*Conclusions@#C2 vertebra can accommodate three (11%) or four (85%) screws in 96% of cases.

ABSTRACT

Treatment options for patients with chronic kidney disease (CKD) are currently limited; therefore, there has been significant interest in applying mesenchymal stem/stromal cell (MSC)-based therapy to treat CKD. However, MSCs harvested from CKD patients tend to show diminished viability and proliferation due to sustained exposure to uremic toxins in the CKD environment, which limits their utility for cell therapy. The application of melatonin has been demonstrated to improve the therapeutic efficacy of MSCs derived from and engrafted to tissues in patients suffering from CKD, although the underlying biological mechanism has not been elucidated. In this study, we observed overexpression of hexokinase-2 (HK2) in serum samples of CKD patients and MSCs harvested from an adenine-fed CKD mouse model (CKD-mMSCs). HK2 upregulation led to increased production levels of methylglyoxal (MG), a toxic metabolic intermediate of abnormal glycolytic processes. The overabundance of HK2 and MG was associated with impaired mitochondrial function and low cell proliferation in CKD-mMSCs. Melatonin treatment inhibited the increases in HK2 and MG levels, and further improved mitochondrial function, glycolytic metabolism, and cell proliferation. Our findings suggest that identifying and characterizing metabolic regulators such as HK2 in CKD may improve the efficacy of MSCs for treating CKD and other kidney disorders.

ABSTRACT

Objective@#We aimed to investigate the characteristics and prognostic factors of coronavirus disease 2019 (COVID-19) patients in the emergency departments (EDs) in Daegu, Korea, the region with the second regional outbreak worldwide. @*Methods@#We conducted a retrospective observational multicenter study using a population-based COVID-19 registry of EDs. We included the demographic, clinical and laboratory data. Cox proportional hazard regression analysis was performed to identify the prognostic factors of mortality. @*Results@#A total of 241 patients were included in this study. In the Cox hazard regression model (hazard ratio [95% confidence interval]), age (65-79 years: 3.531 [1.529-8.156], ≥80 years: 5.335 [2.229-12.770]), respiratory rate (RR) (>20 breaths/min: 2.025 [1.205-3.403], ≤11 breaths/min: 111.292 [30.845-401.555]), lymphocyte counts 23 mg/dL (2.047 [1.233-3.399]), aspartate aminotransferase (AST) levels>40 IU/L (1.785 [1.009-3.158]) and neutrophil counts>6.3×109/L (1.638 [1.014-2.644]) were associated with mortality. @*Conclusion@#Age, RR, lymphocyte counts, BUN levels, AST levels and neutrophil counts were prognostic factors in COVID-19 patients in the ED. These factors can help effectively treat and reduce mortality through optimized management of COVID-19 patients, in places with limited emergency medical resources such as massive regional outbreaks.

ABSTRACT

Orbeez is a small toy made of a highly expandable, which has recently become popular in Korea. These beads can expand to 100 times or more its volume when in contact with water and can also be expected to grow in size when ingested. We encountered two pediatric patients who swallowed Orbeez and developed small bowel obstruction. In the first case, surgery was performed without knowing that the small bowel obstruction was caused by Orbeez. In the second case, based on the experience gained from the first case, a detailed history was taken, including the possibility of Orbeez ingestion to determine the cause of the small bowel obstruction. We diagnosed the cause of the small bowel obstruction early, followed by rapid treatment. We recommend that emergency department physicians must consider Orbeez as the cause of small bowel obstruction in children.

ABSTRACT

Background/Aims@#Recurrent acute myocardial infarction (AMI) is an adverse cardiac event in patients with a first AMI. The predictors of recurrent AMI after the first AMI in patients who underwent successful percutaneous coronary intervention (PCI) have not been elucidated. @*Methods@#We analyzed the data collected from 9,869 patients (63.2 ± 12.4 years, men:women = 7,446:2,423) who were enrolled in the Korea Acute Myocardial Infarction Registry-National Institute of Health between November 2011 and October 2015, had suffered their first AMI and had received successful PCI during the index hospitalization. Multivariable logistic regression analysis was performed to identify the independent predictors of recurrent AMI following the first AMI. @*Results@#The cumulative incidence of recurrent AMI after successful PCI was 3.6% (359/9,869). According to the multivariable logistic regression analysis, the significant predictive factors for recurrent AMI were diabetes mellitus, renal dysfunction, atypical chest pain, and multivessel disease. @*Conclusions@#In this Korean prospective cohort study, the independent predictors of recurrent AMI after successful PCI for the first AMI were diabetes mellitus, renal dysfunction, atypical chest pain, and multivessel disease.

ABSTRACT

Objective@#This study aims to identify significant factors such as sweat that can be used as important predictors of acute coronary syndrome (ACS) in patients visiting the emergency department (ED) complaining of chest pain. @*Methods@#This observational, retrospective, registry-based study conducted from May 2020 to November 2020 evaluated patients who visited the ED due to chest pain. Parameters associated with ACS were investigated, and the clinical characteristics and symptoms were analyzed. @*Results@#A total of 230 patients visited the ED with chest pain. Of these, 94 (40.9%) were diagnosed with ACS. Univariate regression analysis showed that facial sweating (odds ratio [OR], 2.624; 95% confidence interval [CI], 1.241-5.549; P=0.012) and drench sweating (OR, 3.346; 95% CI, 1.602-6.991; P=0.001) were associated with ACS. Hence, we classified these patients as the actual sweating group. However, the sweaty feeling self-reported by patients with no visible sweat did not correlate with ACS. Multivariate logistic regression analysis showed that age (OR, 1.043; 95% CI, 1.016-1.071; P=0.002), quantum of smoking (OR, 1.023; 95% CI, 1.005-1.041; P=0.010), diastolic blood pressure (OR, 1.028; 95% CI, 1.004-1.049; P=0.009), squeezing chest pain (OR, 2.128; 95% CI, 1.000-4.531; P=0.050), and actual sweating (OR, 2.300; 95% CI, 1.209-4.374; P=0.011) were significantly associated with ACS. @*Conclusion@#Age, the quantum of smoking, diastolic blood pressure, squeezing chest pain, and actual sweating are useful predictors for ACS diagnosis. Unlike actual sweating, patient-reported sweating is not significantly related to the diagnosis of ACS. The results of this study will be beneficial in predicting ACS to ensure early and emergency medical care in the pre-hospital setting.

ABSTRACT

Since dissociative identity disorder (DID) has symptoms similar to schizophrenia, such as auditory hallucinations and delusional thoughts of being controlled, there are difficulties in its differential diagnosis. A 16-year-old adolescent male patient who was previously diagnosed with schizophrenia from a different hospital was admitted to our inpatient psychiatric unit for the evaluation of auditory hallucinations and suicide attempts. Through psychiatric evaluations, it was determined that the patient suffered from identity alternation, dissociation, and amnesia. As for the diagnostic evaluations, the following measures were implemented: a psychiatric interview regarding the diagnostic criteria, mental status examination, laboratory tests, brain imaging studies, electroencephalography, and full psychological test for adolescents, and the self-reported measure of the Adolescent Dissociative Experiences Scale. The patient was diagnosed with DID, and the following treatments were administered: pharmacotherapy, ego state therapy, psychoeducation regarding emotions, trauma-focused psychotherapy including stabilization, and family therapy. Following treatment, in the internal dimensions, the patient was able to recognize the nine alternate identities in charge of his emotions, which established a basis for the potential integration of identities. In the external dimensions, he showed improvements in the aspects of family conflicts and issue of school refusal. This is the first reported case of DID in an adolescent in Korea; it emphasizes the consideration of DID in the differential diagnosis of other mental illnesses such as schizophrenia, bipolar disorder, and posttraumatic stress disorder and expands the treatment opportunities for DID by sharing the procedures of ego state therapy.

ABSTRACT

Background/Aims@#Maintaining a mean arterial pressure (MAP) ≥ 65 mmHg during septic shock should be based on individual circumstances, but specific target is poorly understood. We investigated associations between time-weighted average (TWA) hemodynamic parameters during the initial resuscitative period and 28-day mortality. @*Methods@#Prospectively collected data were obtained from a septic shock patient registry, according to the Sepsis-3 definition, between 2016 and 2018. The TWA systolic blood pressure, diastolic blood pressure, MAP, shock index, and pulse pressure (PP) during the first 6 hours after shock recognition were compared. Multivariable regression analysis was performed to assess associations between these parameters and 28-day mortality. @*Results@#Of 340 patients with septic shock, 92 died. Only the median TWA PP differed between the survivors and non-survivors (39.2 mmHg vs. 43.0 mmHg, p = 0.020), whereas the other indexes did not. When PP was divided into quartiles ( 48 mmHg), the mortality rate was higher in the highest quartile (41.2%). Multivariable logistic analysis revealed that PP (odds ratio [OR], 1.28; 95% confidence interval [CI], 1.012 to 1.622; p = 0.039) and PP of > 48 mmHg (OR, 2.25; 95% CI, 1.272 to 3.981; p = 0.005) were independently associated with 28-day mortality. @*Conclusions@#PP was significantly associated with 28-day mortality in patients with septic shock and MAP maintained at > 65 mmHg during the first 6 hours. Further studies are warranted to optimize strategies for maintaining PP and MAP at > 65 mmHg during the early resuscitative period.

ABSTRACT

Objective@#This study aimed to compare the outcomes of adult out-of-hospital cardiac arrest (OHCA) before and after the coronavirus disease 2019 (COVID-19) outbreak in a large metropolitan city. @*Methods@#This before-and-after observational study used a prospective citywide OHCA registry. Adult patients with emergency medical service-treated OHCA, with presumed cardiac etiology, pre- and post-COVID-19 outbreak were enrolled. The study period spanned 2 months, starting from February 18, 2020. The control period was 2 months from February 18, 2019. The primary and secondary outcomes were good neurologic outcome and survival to hospital discharge, respectively. The association between the COVID-19 outbreak and OHCA outcomes was assessed using multivariable logistic regression analysis. @*Results@#This study analyzed 297 OHCA patients (control period, 145; study period, 152). The bystander cardiopulmonary resuscitation rates were 64.8% and 60.5% during the control and study periods, respectively. Response and on-scene times increased by 2 minutes, supraglottic airway use increased by 35.6%, and mechanical chest compression device use increased by 13% post-COVID-19 outbreak. Good neurologic outcome was significantly lower during the study period in overall OHCAs (adjusted odds ratio, 0.23; 95% confidence interval, 0.05–0.98) and in witnessed OHCAs (adjusted odds ratio, 0.14; 95% confidence interval, 0.02–0.90). No significant difference was found in the survival to hospital discharge of OHCA patients between the two periods. @*Conclusion@#During the COVID-19 pandemic, the response and on-scene times were longer, and good neurologic outcome was significantly lower than that in the control period.

ABSTRACT

Objectives@#To determine basic patient characteristics and biomarkers to help in the early diagnosis of Coronavirus disease 2019 (COVID-19) pneumonia in patients with pneumonia who visited the emergency department (ED). @*Methods@#This retrospective study evaluated patients diagnosed with community-acquired pneumonia (CAP) or COVID-19 pneumonia in ED at four tertiary medical centers between February 1 and March 31, 2020. Parameters related to the differential diagnosis between CAP and COVID-19 were investigated. Clinical characteristics and laboratory results of biomarkers were analyzed. @*Results@#In total, 81 patients presented to the ED with COVID-19 pneumonia. Multivariate logistic regression analysis showed that monocyte count [odds ratio (OR): 0.996; 95% confidence interval (CI): 0.994–0.999] and pneumonia severity index (PSI) [OR: 1.025; 95% CI: 1.002–1.049] were associated with diagnosis of COVID-19 pneumonia. The area under the curve comprising the combination of monocyte and PSI was 0.789. @*Conclusion@#Differential diagnosis of COVID-19 pneumonia from pneumonia patients who visited the emergency room can be made by monocyte count and PSI score.

ABSTRACT

Background@#Acute ischemic stroke is a time-sensitive disease. Emergency medical service (EMS) prehospital notification of potential patients with stroke could play an important role in improving the in-hospital medical response and timely treatment of patients with acute ischemic stroke. We analyzed the effects of FASTroke, a mobile app that EMS can use to notify hospitals of patients with suspected acute ischemic stroke at the prehospital stage. @*Methods@#We conducted a retrospective observational study of patients diagnosed with acute ischemic stroke at 5 major hospitals in metropolitan Daegu City, Korea, from February 2020 to January 2021. The clinical conditions and time required for managing patients were compared according to whether the EMS employed FASTroke app and further compared the factors by dividing the patients into subgroups according to the preregistration received by the hospitals when using FASTroke app. @*Results@#Of the 563 patients diagnosed with acute ischemic stroke, FASTroke was activated for 200; of these, 93 were preregistered. The FASTroke prenotification showed faster door-tocomputed-tomography times (19 minutes vs. 25 minutes, P < 0.001), faster door-to-intravenousthrombolysis times (37 minutes vs. 48 minutes, P < 0.001), and faster door-to-endovascularthrombectomy times (82 minutes vs. 119 minutes, P < 0.001). The time was further shortened when the preregistration was conducted simultaneously by the receiving hospital. @*Conclusion@#The FASTroke app is an easy and useful tool for prenotification as a regional stroke care system in the metropolitan area, leading to reduced transport and acute ischemic stroke management time and more reperfusion treatment. The effect was more significant when the preregistration was performed jointly.

ABSTRACT

Purpose@#This study analyzed the effects of a health policy capacity development education program as a publicprivate partnership (PPP) model in official development assistance (ODA) for health policy administrators. @*Methods@#Between October 2015 and September 2017, 41 participants from underdeveloped countries completed the three-week education program at K university, following the official selection process of the Korea International Cooperation Agency (KOICA) and each country’s embassy. @*Results@#The effects of the health policy capacity development education program differed significantly according to participants' age (p=.043), country region (p=.045), and academic or professional degree (p=.007). Academic or professional degree significantly predicted the effects of the program (β=.41, p=.007), explaining 21.7% of the variance in the regression model. @*Conclusion@#The current selection process for ODA program participants considers recommendations from each country’s embassy to determine eligible candidates. The hosting institution’s opinions or suggestions regarding participants’ professional expertise or work experience, country region, or demographic characteristics should also be considered in the participant selection process.

ABSTRACT

Objective@#Coronary angiography (CAG) is an important procedure in post-resuscitated patients with out of hospital cardiacarrest (OHCA). On the other hand, the timing of CAG is still controversial. This study investigated the relationshipbetween electrocardiogram, cardiac enzyme, echocardiographic findings, and early coronary angiography (ECAG). @*Methods@#The medical records of OHCA patients from January 2014 to December 2018 were reviewed retrospectively.The total patients who underwent CAG for OHCA caused by cardiac origin were 48. They were divided into two groupsaccording to survival discharge. The ECAG was defined as the time from reporting 119 to the CAG within two hours. Thefollowing items in the two groups were also analyzed: the prehospital factors, such as witnessed arrest, bystander cardiopulmonaryresuscitation, shockable rhythm, and arrest to return of spontaneous circulation time; and the hospital factors,such as the timing of CAG, ST-segment elevation or depression in the electrocardiogram, troponin-I elevation, andtransthoracic echocardiography findings. @*Results@#Twenty-seven patients out of 48 patients with OHCA (56.3%) underwent ECAG. In the survival group (n=35),ECAG incidence was significantly higher than the death group (n=24 [68.6%] vs. n=3 [23.1%], P=0.008) and the adjustedodds ratio of ECAG for predicting survival discharge was 10.69 (95% confidence interval, 1.7-68.8). @*Conclusion@#In this retrospective study, the patients applied with ECAG showed a better prognosis in the survival dischargerate than the patients with delayed CAG.
