We aimed to evaluate the predictors of subclinical coronary atherosclerosis in individuals without traditional cardiovascular risk factors. We analyzed 2,061 individuals without identified cardiovascular risk factors who voluntarily underwent coronary computed tomography angiography as part of a general health examination.

Metformin, the first-line drug for type 2 diabetes mellitus (T2DM), has additional effects on improvements of nonalcoholic fatty liver disease (NAFLD); however, there are no treatments for both T2DM and NAFLD. Previous studies have shown hepatoprotective effects of a mixture of lemon balm and dandelion (LD) through its antioxidant and anti-steatosis properties. Thus, combination effects of metformin and LD were examined in a high-fat diet (HFD)-induced metabolic disease mouse model.

Limited data exist regarding the association between right bundle branch block (RBBB) and subclinical coronary atherosclerosis. This study investigated the influence of RBBB on subclinical coronary atherosclerosis detected by coronary computed tomographic angiography (CCTA) in an asymptomatic population. We retrospectively analyzed 7,205 asymptomatic individuals (mean age 54.

Anticancer drug release via stents, however, needs to be optimized with respect to drug delivery behavior for the stents to be effective for prolonged containment of tumor proliferation and stent re-obstruction. Local stent-based drug delivery has been tested using an effective anti-cancer drug, gemcitabine, but the release from the stent-coated polyurethane films is often too fast and the drug is depleted from the coated film virtually in a day.

Methods: Patients with ileocolic intussusception (ICI) during the years 2007-2019 were included. Demographic data, recurrences, and outcomes were analyzed.
Purpose: We performed this prospective cohort study to compare the accuracy and technical characteristics of ultra-low-dose CT cystography with those of conventional retrograde cystography.
Materials And Methods: A cohort of 31 patients referred for cystography after bladder repair were enrolled. To detect urine leakage, we initially performed conventional cystography after retrograde distention of the bladder with dilute iodinated contrast material, followed by ultra-low-dose CT cystography.
Purpose: To use adenosine-induced stress CT myocardial perfusion imaging (CT-MPI) to determine normal reference values for left ventricle (LV) wall thickness (WT) and motion parameters.
Methods: This study included 106 Korean subjects (52 men and 54 women) who underwent CT-MPI due to chest pain, but were not found to have any detectable mild or severe coronary artery disease or myocardial perfusion defect. The following quantitative parameters were assessed on the CT-MPI according to a 17-segment model: LV myocardial thickness at end-systolic (WT) and end-diastolic (WT) phases, systolic wall thickening (SWT), and wall motion (WM).
Purpose: Rotavirus infection has recently been reported to be associated with seizures accompanied by leukoencephalopathy in newborns. We aimed to determine long-term outcomes and prognostic factors in newborns with neonatal seizures caused by rotavirus-associated leukoencephalopathy.
Methods: We retrospectively reviewed the records and brain magnetic resonance (MR) images of 32 patients who fulfilled the following criteria: (1) neonatal seizures, (2) distinctive symmetric cerebral white matter lesions on diffusion-weighted MR images (DWI), (3) rotavirus infection, (4) absence of a specific etiology of seizures, except for the aforementioned DWI lesions, and (5) Korean Bayley Scales of Infant Development II (K-BSID-II) assessment after 12 months of age.
Objective: The purpose of this study was to identify whether there is an increase in type I interferon and proinflammatory cytokine levels in the cerebrospinal fluid of newborns with rotavirus-associated leukoencephalopathy.
Methods: Levels of type I interferons (interferon-alpha and interferon-beta) and proinflammatory cytokines (interleukin-6 and interferon-gamma) were measured in the cerebrospinal fluid of 23 newborns with rotavirus-associated leukoencephalopathy (patient group) and 39 infants under 90 days-of-age (control group).
Results: Cerebrospinal fluid pleocytosis was not observed in either group.

Aims: To compare the diagnostic accuracy of on-site computed tomography (CT)-derived fractional flow reserve (FFR) and stress CT myocardial perfusion (CTP) in patients with coronary artery disease.
Methods And Results: Using a prospective CTP registry, 72 patients with invasive FFR were enrolled. CT-derived FFR was computed on-site using rest-phase CTP data.
Serum phosphorus (P) concentration is associated with coronary artery calcification (CAC) as well as cardiovascular events in patients with chronic kidney disease. It has been suggested that this relationship is extended to subjects without renal dysfunction, but further explorations in diverse races and regions are still needed. We performed a cross-sectional study of 2,509 Korean subjects (Far Eastern Asian) with an estimated glomerular filtration rate of ≥60 ml/min/1.

Microangiopathy is an uncommon and distinct form of simple tumor pulmonary embolism. Here, we present a 52-year-old male with tumor thrombotic microangiopathy and pulmonary infarction, which might have originated from intraductal papillary mucinous tumor of the pancreas.

It has a well-established safety profile, and most of its side effects are known to be mild and transient. Until now, coronary vasospasm has been rarely reported as a side effect of adenosine during or after adenosine stress test.

The reproducibility of CAC measurements makes it clinically useful for the assessment of progression and regression of coronary atherosclerosis. This study assessed the reproducibility of the Agatston CAC score among patients undergoing 256-slice multidetector computed tomography (MDCT) scans using 0.

Methods: We enrolled a total of 4 groups such as patients with gastrointestinal stromal tumor (GIST) (26 patients), those with paraganglioma (9 patients), those with primary sarcomas (13 patients, excluding those with liposarcoma), and those with desmoid tumor (6 patients). The reviewers evaluated the presence of tumor vessels capable of directly tracing from the tumor margin to the named vessels.
Background And Aims: Some full-term neonates presenting seizures show diffusion-restricted lesions in the cerebral white matter on brain diffusion-weighted imaging (DWI). The purpose of this study was to describe the clinical characteristics and DWI findings in a group of neonates with seizures, white matter lesions on DWI, and a high incidence of rotavirus infection.
Methods: Total 30 full-term neonates with seizures were admitted between 2008 and 2010.
Background: The current standard of care is to delay noncardiac procedure (NCP) 5 to 7 days after discontinuation of antiplatelet agents (APAs) in patients with coronary stents. However, it is often difficult to follow because of concerns over stent thrombosis. The point-of-care aspirin/P2Y(12) assay (VerifyNow; Accumetrics Inc, San Diego, CA) is useful to evaluate platelet reactivity in conjunction with APAs.

Materials And Methods: A cohort of 1035 men who visited our hospital's health promotion center and were checked for serum PSA levels more than two times between January 2001 and November 2011 were included. Among them, 116 patients had a change in PSA levels from less than 4 ng/mL to more than 4 ng/mL and underwent transrectal ultrasound guided prostate biopsy.
