Objective:
To analyze costs and cost-effectiveness of transforaminal endoscopic thoracic discectomy (TETD) for the treatment of symptomatic thoracic disc herniation (TDH) and compare it with open microdiscectomy (MD).
Methods:
This retrospective cohort study included patients who underwent TETD or MD for symptomatic TDH and had a minimum follow-up of 1 year. Cost analysis included direct costs (primary and secondary hospital costs), indirect costs (lost wages due to work absence), total costs (direct + indirect), and cost-effectiveness (cost per quality-adjusted life year [QALY] and incremental cost-effectiveness ratio [ICER]). Clinical outcomes included patient-reported outcome measures (Oswestry Disability Index [ODI], 36-item Short Form health survey [SF-36]), QALY gained, and reoperation and readmission rates at 1 year. TETD and MD groups were compared for outcome measures.
Results:
A total of 111 patients (57 TETD, 54 MD) were included. The direct ($6,270 TETD vs. $7,410 MD, p < 0.01), indirect costs ($1,250 TETD vs. $1,450 MD, p < 0.01), total costs ($7,520 TETD vs. $8,860 MD, p < 0.01), and cost per QALY ($31,333 TETD vs. $44,300 MD, p < 0.01) were significantly lower for TETD compared to MD. ICER of TETD was found to be -$33,500. At 1 year, TETD group showed significantly greater improvement in ODI (46% vs. 36%, p < 0.01) and SF-36 (64% vs. 53%, p < 0.01) and significantly greater QALY gained (0.24 vs. 0.2, p < 0.01) compared to MD group. No significant difference was found in reoperation and readmission rates.
Conclusion
TETD demonstrated significantly better clinical outcomes, lower overall costs, and better cost-effectiveness than MD in appropriately selected patients of symptomatic TDH.

Tuberculosis and Respiratory Diseases 2021;84(2):125-133
Background:
The coronavirus disease (COVID-19) can manifest in a range of symptoms, including both asymptomatic systems which appear nearly non-existent to the patient, all the way to the development of acute respiratory distress syndrome (ARDS). Specifically, COVID-19–associated pneumonia develops into ARDS due to the rapid progression of hypoxia, and although arterial blood gas analysis can assist in halting this deterioration, the current environment provided by the COVID-19 pandemic, which has led to an overall lack of medical resources or equipment, has made it difficult to administer such tests in a widespread manner. As a result, this study was conducted in order to determine whether the levels of oxygen saturation (SpO2) and the fraction of inhaled oxygen (FiO2) (SF ratio) can also serve as predictors of ARDS and the patient’s risk of mortality.
Methods:
This was a retrospective cohort study conducted from February 2020 to Mary 2020, with the study’s subjects consisting of COVID-19 pneumonia patients who had reached a state of deterioration that required the use of oxygen therapy. Of the 100 COVID-19 pneumonia cases, we compared 59 pneumonia patients who required oxygen therapy, divided into ARDS and non-ARDS pneumonia patients who required oxygen, and then investigated the different factors which affected their mortality.
Results:
At the time of admission, the ratios of SpO2, FiO2, and SF for the ARDS group differed significantly from those of the non-ARDS pneumonia support group who required oxygen (p<0.001). With respect to the predicting of the occurrence of ARDS, the SF ratio on admission and the SF ratio at exacerbation had an area under the curve which measured to be around 85.7% and 88.8% (p<0.001). Multivariate Cox regression analysis identified that the SF ratio at exacerbation (hazard ratio [HR], 0.916; 95% confidence interval [CI], 0.846–0.991; p=0.029) and National Early Warning Score (NEWS) (HR, 1.277; 95% CI, 1.010–1.615; p=0.041) were significant predictors of mortality.
Conclusion
The SF ratio on admission and the SF ratio at exacerbation were strong predictors of the occurrence of ARDS, and the SF ratio at exacerbation and NEWS held a significant effect on mortality.

Purpose:
This study aimed to update the previously published nursing practice guideline for oral care.
Methods:
The guideline were updated according to the manuals developed by National Institute for Health and Care Excellence (NICE) and Scottish Intercollegiate Guidelines Network (SIGN), and a Handbook for Clinical Practice Guideline Developer Version 1.0.
Results:
Updated nursing practice guideline for oral care was consisted of 10 domains and 79 recommendations. The number of recommendations in each domain were: 5 general issues, 2 oral care indications, 9 oral assessment, 16 general oral care, 12 oral care for critically ill patients, 16 oral care for cancer patients, 12 oral care for cancer patients with oral complications, 5 oral care education, 1 oral care referral, and 1 documentation and report. In terms of grades for recommendations, 11.4% was grade A, 17.0% was grade B, and 68.2% was grade C. Twelve new recommendations were developed and 7 previous recommendations were deleted.
Conclusion
Updated nursing practice guideline for oral care is expected to serve as an evidence-based practice guideline for oral care in South Korea. It is recommended that this guideline be spread to clinical nursing settings nationwide to improve the effectiveness of oral care practice.

PURPOSE: Patients in the intensive care unit (ICU) are more susceptible to nosocomial infections, including central line-associated bloodstream infection (CLABSI), surgical site infection, urinary tract infection or ventilator-associated pneumonia. This study is a comparative analysis of how central venous catheter (CVC) management staff affects CLABSI. METHODS: We performed a two-phase review of all patients transferred to the surgical ICU (SICU) from January 2013 to June 2014. CVC management staff was introduced in October 2013. Electronic medical records provided the data for a comparative analysis of incidence rates and risks of CLABSI, as well as the subjects' general characteristics. RESULTS: This study included 248 patients before the introduction of a CVC management staff member and 196 patients after the introduction. General patient characteristics before and after the CVC management staff was in place did not differ significantly. The CLABSI rate decreased by 4.61 cases/1,000 device days after the introduction (6.26 vs. 1.65; odds ratio, 4.47; 95% confidence interval, 1.39~14.37; p=0.009). However, the mortality rate and length of ICU stay did not change after CVC management staff was in place (12.9% vs. 10.7%, p=0.480; 16.00±24.89 vs. 15.87±18.80, p=0.954; respectively). CONCLUSION: In this study, the introduction of CVC management staff effectively reduced CLABSI rates in current ICU system.

OBJECTIVE: To evaluate the differences in maxillomandibular transverse measurements at either the crown or the estimated center of resistance (CR), and to compare values between normal occlusion and Class III malocclusion groups. METHODS: Dental casts and computed tomography (CT) data from 30 individuals with normal occlusion and 30 with skeletal Class III malocclusions were evaluated. Using the casts, dental arch widths (DAWs) were measured from the cusp tips, and basal arch widths (BAWs-cast) were measured as the distance between the points at the mucogingival junction adjacent to the respective cusp tips. The BAWs determined from CT (BAWs-CT) images were measured from the estimated CRs of the teeth. RESULTS: None of the DAW measurements or maxillomandibular DAW differences showed statistically significant intergroup differences. In contrast, the maxillary BAWs-CT and BAWs-cast were lesser in the Class III malocclusion group than in the normal occlusion group. The mandibular BAWs-CT were significantly greater in the Class III malocclusion group than in the normal occlusion group. Moreover, the maxillomandibular BAW differences on both CT and cast showed significant intergroup differences in all transverse measurements. CONCLUSIONS: The maxillomandibular DAW differences showed no significant intergroup differences. In contrast, the maxillomandibular BAW differences on both CT and cast showed significant intergroup differences in all transverse measurements. The maxillomandibular BAW differences at the estimated CRs, measured using CT or casts, can reveal underlying transverse maxillary basal arch deficiencies in patients with skeletal Class III malocclusions.

BACKGROUND: Viridans streptococci (VS) are a large group of streptococcal bacteria that are causative agents of community-acquired respiratory tract infection. However, data regarding their clinical characteristics are limited. The purpose of the present study was to investigate the clinical and radiologic features of community-acquired pneumonia (CAP) with or without parapneumonic effusion caused by VS. METHODS: Of 455 consecutive CAP patients with or without parapneumonic effusion, VS were isolated from the blood or pleural fluid in 27 (VS group, 5.9%) patients. Streptococcus pneumoniae was identified as a single etiologic agent in 70 (control group) patients. We compared various clinical parameters between the VS group and the control group. RESULTS: In univariate analysis, the VS group was characterized by more frequent complicated parapneumonic effusion or empyema and bed-ridden status, lower incidences of productive cough, elevated procalcitonin (>0.5 ng/mL), lower age-adjusted Charlson comorbidity index score, and more frequent ground glass opacity (GGO) or consolidation on computed tomography (CT) scans. Multivariate analysis demonstrated that complicated parapneumonic effusion or empyema, productive cough, bed-ridden status, and GGO or consolidation on CT scans were independent predictors of community-acquired respiratory tract infection caused by VS. CONCLUSION: CAP caused by VS commonly presents as complicated parapneumonic effusion or empyema. It is characterized by less frequent productive cough, more frequent bed-ridden status, and less common CT pulmonary parenchymal lesions. However, its treatment outcome and clinical course are similar to those of pneumococcal pneumonia.
