A substantial, immediate healthcare burden for screening of Coronavirus disease 2019 (COVID-19) is created when large-scale outbreaks occur. There have been a series of measures to strengthen the screening process through robust public-private partnerships between Hanam City Public Health Center (PHC), the local medical association, and central/provincial government. A partnership between PHC and the local physician’s group in Hanam City established the Respiratory Clinic. The PHC provided the infrastructure for the Respiratory Clinic including medical facilities, supplies (i.e. personal protective equipment), and administrative support. A total of 11 registered physicians from the local physicians group agreed to participate in clinical service provided at the Respiratory Clinic. Any citizens with COVID-19 suspected respiratory symptoms call the COVID-19 hotline and visit the Respiratory Clinic if required. Responding to COVID-19 outbreaks will be a continual process, and the screening system is essential support to public health interventions, and crucial in the response to a surge in COVID-19 cases.

The severe form of chronic periodontitis(CP) has been reported to be strongly associated with the presence of allele 2 of composite IL-1B(+3954) and IL-1A(+4845) genetic polymor- phisms(genotype positive). However, other studies have reported conflicting findings. These might have resulted from differences in ethnic background and disease entities. The aim of this study was to determine the distribution of IL-1A(+4845), IL-1B(+3954), IL-1B(-511), and IL-1 RN(VNTR) genetic polymorphisms in children as a future Korean population. The study population consisted of 92 children from the Dept. of Pediatric Den- tistry, Chonnam National University Hospital. Genomic DNA was obtained from buccal swab. The IL-1A(+4845), IL-1B(+3954), and IL-1B(-511) genes were genotyped by amplifying the polymorphic region using multiplex polymerase chain reaction(PCR), followed by restriction enzyme digestion and gel electrophoresis. IL-1 RN(VNTR) polymorphism were then evaluat- ed by PCR amplification and fragment size analysis in agarose gel. The allele 2 frequency was 41.3%, 4.3%, 47.8%, and 9.9% for IL-1A(+4845), IL-1B(+3954), IL-1B(-511), and IL-1 RN respectively. The frequency of genotype with allele 2 carriage for IL-1A(+4845), IL-1B(+3954), IL-1B(-511), and IL-1 RN was 77.1%, 7.6%, 63.0%, and 15.2% respectively. The allele 2 frequency in IL-1B(+3954) was significantly higher in female than in male population(p<0.05). The negative association was shown between the presence of allele 2 in IL-1B(-511) and in IL-1B(+3954), and the carriage rate of IL-1B(+3954) allele 2 tended to lower in IL-1B(-511) allele 2(P=0.056). Only 7.3% of children carried the composite genotype of IL-1A(+4845) and IL-1B(+3954). These results suggest that the polymorphism of IL-1B(+3954) and the positive composite genotype was relatively rare in Korean population.

Time intervals and indices of left ventricular diastolic filling were studied by M-mode and pulsed Doppler Echocardiography in 18 dilated cardiomyopathy patients. After one two hours captopril(capril(R)) 25mg medication. 1)Systolic blood pressure, Diastolic blood pressure, Heart rate were significantly decreased. 2) Dimensions of LVSD, LVDD, LA, Aorta and EF were not changed measured by M-mode echocardiography. 3) IRT measured by M-mode and Pulsed Doppler echocardiography were significantly increased(45+/-33msec VS 74+/-35msec. 84+/-32msec VS 100+/-22msec P<0.05). 4) A2-E measured by M-mode and Pulsed Doppler echocardiography were significantly increased(114+/-45msec VS 134+/-46msec, 156+/-46msec VS 194+/-48msec, P<0.05). 5) Deceleration time was significantly increased(137+/-36msec VS 205+/-40msec P<0.05). 6) Transmitral peak flow velocities were not changed significantly. In summary captopril influences early diastolic time intervals with dilated cardiomyopathy patients and we interpreted these effects be beneficial on diastolic filling pattern.

We evaluated the neutralizing activity in serum from three patients >1 year after recovery from Middle East respiratory syndrome (MERS) associated with mild pneumonia treated with antivirals during the MERS outbreak in South Korea at 2015. The neutralizing activity in serum was measured by pseudovirus inhibition assays. Three-fold diluted serum of subjects showed only 9.7%, 10.3%, and 2.2% reductions in relative light units. So, significant neutralizing activity was not demonstrated in any sera of three patients with mild pneumonia >1 year after being successfully treated with antiviral agents and recovering from MERS coronavirus infection.

Although metabolic syndrome (MetS) is associated with increased cardiovascular mortality and the development of atherosclerosis, consensus is still lacking on the status of cardiovascular function and geometry in MetS patients. We investigated the relation between MetS and left ventricle (LV) geometry and function, carotid intima-media thickness (IMT) and arterial stiffness in a community-based cohort of 702 adult subjects. Subjects were categorized into three groups according to the number of MetS components present, as defined by the Adult Treatment Panel III guidelines: 1) Absent (0 criteria), 2) Pre-MetS (1-2 criteria) or 3) MetS (> or =3 criteria). In female subjects, LV mass, LV mass/height(2.7), deceleration time, and aortic pulse wave velocity increased, and E/A ration decreased in a stepwise manner across the three groups. These changes were not observed in male subjects. The mean carotid IMT was higher in the MetS group than in the other two groups. The degree of MetS clustering is found to be strongly correlated with geometric eccentricity of LV hypertrophy, diastolic dysfunction and arterial changes irrespective of age and blood pressure status, particularly in females. Waist circumference is found to have the most powerful effect on cardiovascular parameters.

OBJECTIVES: This study was performed to standardize the Korean Version of Calgary Depression Scale for Schizophrenia (K-CDSS), a semi-structured interview scale to assess depression in schizophrenia patients and to determine the psychometric properties and clinical utility of the K-CDSS. METHODS: Sixty-one patients diagnosed as schizophrenia by DSM-IV criteria were recruited in this study. Then, the patients were interviewed using the Structure Clinical Interview for DSM-IV (SCID) by a trained psychologist. Subsequently, the KCDSS, Positive and Negative Syndrome Scale (PANSS), Hamilton Depression Rating Scale (HDRS), Montgomery-Asberg Depression Rating Scale (MADRS) and Simpson Angus Rating Scale (SAS) were administered by a psychiatrist. Lastly, the K-CDSS was re-assessed by a second independent rater without any previous information of patients to confirm the inter-rater reliability. RESULTS: The internal consistency using Cronbach's alpha was 0.852. Inter-rater reliability using Intraclass Correlation Coefficient (ICC) for single items and for sum score were 0.659-0.889 and 0.963, respectively. K-CDSS was assessed by a second Factor analysis and ROC (receiver operating characteristic) curve analysis were conducted. The factor analysis revealed a single factor that accounted for 53.7% of the total variance, suggesting that the uni-dimensional structure of the K-CDSS may be retained. In addition, K-CDSS showed a good convergent validity with very strong correlations with HDRS (r=0.75) and MADRS (r=0.81), respectively. However, K-CDSS was not correlated with PANSS-positive, PANSS-negative and SAS, demonstrating its satisfactory discriminant validity. The area under the ROC curve was 0.968 (standard error=0.036, p<.001). With a cut-off point of 8, the K-CDSS had a sensitivity 83.3%, specificity 97.9%, positive predictive value 90.9% and negative predictive value 95.8%. CONCLUSION: K-CDSS is considered as a short and valid tool to identify depressive symptoms in schizophrenia.

OBJECTIVE: The purpose of this study was to evaluate any improvement in the quality of abdominal CTs after the utilization of the nationally based accreditation program. MATERIALS AND METHODS: Approval was obtained from the Institutional Review Board, and informed consent was waived. We retrospectively analyzed 1,011 outside abdominal CTs, from 2003 to 2007. We evaluated images using a fill-up sheet form of the national accreditation program, and subjectively by grading for the overall CT image quality. CT scans were divided into two categories according to time periods; before and after the implementation of the accreditation program. We compared CT scans between two periods according to parameters pertaining to the evaluation of images. We determined whether there was a correlation between the results of a subjective assessment of the image quality and the evaluation scores of the clinical image. RESULTS: The following parameters were significantly different after the implementation of the accreditation program: identifying data, display parameters, scan length, spatial and contrast resolution, window width and level, optimal contrast enhancement, slice thickness, and total score. The remaining parameters were not significantly different between scans obtained from the two different periods: scan parameters, film quality, and artifacts. CONCLUSION: After performing the CT accreditation program, the quality of the outside abdominal CTs show marked improvement, especially for the parameters related to the scanning protocol.

BACKGROUND: In an era of medical cost containment, cost-effectiveness has become a major focus in healthcare. The effect of a new policy on the use of low fresh gas flow during maintenance of general anesthesia with volatile anesthetics was evaluated. METHODS: The numbers and duration of general anesthesia cases using sevoflurane 5 weeks prior to and 15 weeks after policy implementation were retrieved from the electronic medical records database. The number of sevoflurane bottles consumed was also assessed. The anesthesia hours per bottle of sevoflurane were compared before and after policy implementation. RESULTS: The number of anesthesia hours performed per bottle of sevoflurane increased by 38.3%. The effect varied over time and tended to fade with time. CONCLUSIONS: The implementation of a low fresh gas flow rate policy effectively reduces the amount of sevoflurane consumed for the same duration of anesthesia.

OBJECTS: Some studies have suggested that brain-derived neurotrophic factor(BDNF), one of the most important neurotrophins, is involved in pathophysiology of depression and suicide. This study was performed to determine whether there is an abnormality in plasma BDNF concentration in suicidal attempters. METHODS: The subjects were 71 suicidal attempters who visited emergency rooms in multi-medical centers. All subjects had been interviewed by using Structured Clinical Interview for DSM-IV(SCID), Hamilton Depression Rating Scale(HDRS), Young Mania Rating Scale(YMRS), and Positive And Negative Syndrome Scale(PANSS). The severity of the suicidal behavior was measured by Lethality of Suicide Attempt Rating Scale(LSARS) and Risk-Rescue Rating(RRR) system. Seventy-one age, sex, and diagnosis matched non-suicidal psychiatric patients who were consecutively admitted to a psychiatric ward during the same period recruited as psychiatric controls. They were drug-naive or drug-free at least more than 2 months. In addition, 80 healthy controls were randomly selected as normal controls. Plasma BDNF level was measured by the enzyme linked immunosorbent assay(ELISA) methods. RESULTS: In overall F-test, differences of the plasma BDNF levels among the groups were statistically significant(F=20.226, p<0.001). In the multiple comparisons(Scheffe), while mean levels of plasma BDNF between normal controls and non-suicidal psychiatric patients were similar(p=0.984), the BDNF levels of suicidal attempters were lower than those of other two groups(p<0.001). LSARS and RRR did not reveal any significant correlations with BDNF levels in suicidal attempters. CONCLUSION: These results suggest that reduction of plasma BDNF level is related to suicidal behavior and BDNF level may be a biological marker of suicidal behavior.
