PURPOSE: The AFX2 endograft is a unibody, bifurcated stent graft that can be used to lower complications in certain patients. In this study, we retrospectively reviewed consecutive cases in which the AFX2 system was used to overcome the challenges of narrow distal aorta, as well as to reduce procedure time and contrast medium dose. Furthermore, we compared the results with matched patients treated using the Endurant II endograft system. MATERIALS AND METHODS: This was a retrospective observation

Visual acuity (VA) is a measure of the ability to distinguish shapes and details of objects at a given distance and is a measure of the spatial resolution of the visual system. Vision is one of the basic health indicators closely related to a person’s quality of life. It is one of the first basic tests done when an eye disease develops. VA is usually measured by using a Snellen chart or E-chart from a specific distance. However, in some cases, such as the unconsciousness of patients or diseases,

Background: Whether anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibody levels post-third coronavirus disease (COVID-19) vaccination correlate with worse outcomes due to breakthrough infection is unclear. We evaluated the association between anti-SARS-CoV-2 antibody levels and symptomatic breakthrough infection or hospitalization during the Omicron surge in kidney transplant recipients. Methods: In total, 287 kidney transplant recipients expected to receive a third vaccina

Post-transplantation diabetes mellitus (PTDM) negatively affects graft and patient survival after kidney transplantation (KT). This prospective study used continuous glucose monitoring (CGM) to evaluate perioperative blood glucose dynamics, identify PTDM risk factors, and compare predictive accuracy with capillary blood glucose monitoring (CBGM) in 60 non-diabetic living-donor KT recipients. Patients underwent 2-week pre- and postoperative CGM, including routine CBGM during their in-hospital sta

The analysis of I71.3 code for rAAA showed that only 43.0% were true rAAA and the remaining 57.0% were misdiagnosed. This indicates that the I71.3 code is overestimated in National Health Insurance-based data and that the true incidence of rAAA could be much lower.

BACKGROUND: The increasing use of kidneys from elderly donors raises concerns due to age-related nephron loss. Combined with nephrectomy, this loss of nephrons markedly increases the risk of developing chronic kidney disease (CKD). This study aimed to investigate the prognostic value of preoperative kidney cortex volume in predicting the loss of kidney function in elderly donors, by developing an artificial intelligence (AI)-based model for precise kidney volume measurement and applying it to li

Introduction: The plethora of data on glycemic excursions and additional indices, such as the glycemic variability (GV) and glucose management indicator (GMI), which is an estimated A1C derived from the glucose measures that the continuous glucose monitoring (CGM) system provides, has revolutionized the study of dysglycemia on various organs and stress induced situations. GV has been proposed to be a risk factor for complication of diabetes and increased mortality and predictive marker for hypog

본 논문에서는 2000년부터 2013년까지 우리나라의 일반은행, 지방은행 및 은행지주회사의 공시자료로부터 자료를 수집하여 은행의 위험관리 기능을 측정할 수 있는 다양한 변수를 구성하고 이들을 종합적으로 고려하기 위하여 주성분분석을 통해 위험관리지수(risk management index)를 산출하였다. 또한 위험관리지수를 이용하여 우리나라 은행의 내부적인 위험관리의 정도가 실제 위험 및 수익성에 미치는 영향을 패널회귀분석을 통해 실증적으로 분석하였다. 분석 결과 직전연도 은행의 위험관리지수가 높을수록 당해 연도의 테일 리스크가 감소하는 것으로 나타났다. 이로써 국내은행에서 위험관리기능이 강력할수록 테일 리스크를 줄일 수 있음을 밝혔다. 한편, 위험관리기능이 VaR에는 유의한 영향을 미치지 않는 것으로 나타났는데 이러한 차이는 두 위험 측정치가 포착하는 위험의 성격에 차이가 있기 때문인 것으로 보인다. 즉, VaR은 정상적인 시장 여건 하에서 발생할 수 있는 최대 손실을 측정하는 반면

Abnormal and borderline ABI significantly increased the incidence of clinically indicated coronary revascularization and all-cause mortality during a 4-year follow-up among patients with CAD. Hence, ABI could be used to stratify extremely high-risk patients with CAD who may require aggressive surveillance or treatment.

The prevalence of dominant or codominant C1q deposition in transplanted renal allograft biopsies was 1.6%. Most cases did not have any other accompanying glomerular changes. The follow-up biopsies of these allografts showed spontaneous disappearance or diminished staining of C1q deposition. These findings suggest that C1q deposition found in renal allografts is most likely clinically benign, although this possibility should be confirmed in further large-scale studies.

Traditional treatment with anticoagulation in nonfatal submassive pulmonary embolism can result in serious sequelae of chronic thromboembolic pulmonary hypertension or poor exercise tolerance, and functional impairment. To prevent long-term complications in previously healthy young patients, other treatment options to actively resolve existing thrombi should be considered. Despite recommendations for use in only severe clinical presentations, endovascular interventional techniques could serve as

본 논문에서는 2004년부터 2015년까지 국내 중소기업을 대상으로 성향점수짝짓기(Propensity Score Matching) 방법을 이용하여 상장이 투자에 미치는 효과에 대해 연구하였다. 분석 결과 상장 중소기업의 연구개발 투자 규모는 비상장 중소기업에 비해 더 큰 것으로 나타났다. 또한 신규상장 중소기업은 상장으로 조달된 자금을 유형자산 투자와 연구개발 투자에 모두 사용하지만 상장 이전에 레버리지가 높았던 기업들은 조달 자금을 유형자산 투자에 사용하지 않는 것으로 나타났다. 신규상장 중소기업을 대상으로 한 이중차이법(Difference-in-differences) 분석 결과에서는, 상장 이후 유형자산 투자보다는 연구개발 투자의 증가가 상대적으로 더 뚜렷하게 나타남을 확인하였다. 본 연구결과는 최근 부각되고 있는 중소기업 자금조달 창구로서의 주식시장의 역할은 유형자산에 대한 투자 확대보다는 연구개발 투자 촉진에 상대적으로 더 유효할 수 있음을 시사한다.

This research identifies and analyzes various problems that Korean women’s football is facing and offers recommendations for sustainable development by using a qualitative reflective approach. In order to attain these two overarching goals of this study, each of the five researchers shared an extensive record on their perspective on women’s football in South Korea through the process of self-reflection. Furthermore, in an attempt to democratize the data collection process, researchers’ personal
