BACKGROUND Transarterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) may result in acute kidney injury (AKI) like other angiographic interventions. METHODS To investigate the incidence, risk factor and outcomes of AKI after TACE, defined by Acute Kidney Injury Network (AKIN) criteria, we retrospectively analyzed 442 TACE treatment sessions(More)
A neighborhood-level analysis of mortality from suicide would be informative in developing targeted approaches to reducing suicide. This study aims to examine the association of community characteristics with suicide in the 424 neighborhoods of Seoul, South Korea. Neighborhood-level mortality and population data (2005–2011) were obtained to calculate(More)
A novel method of ancient DNA (aDNA) purification was developed using ion-exchange columns to improve PCR-amplifiable DNA extraction from ancient bone samples. Thirteen PCR-resistant ancient bone samples aged 500-3,300 years were tested to extract aDNA using a recently reported, silica-based aDNA extraction method and an ion-exchange column method for the(More)
AIM This paper is a report of a study conducted to determine the usability and utility of the Braden in intensive care units. BACKGROUND An understanding of the clinical usage of the Braden Scale is valuable when considering the incidence of pressure ulcers in a critical-care setting. METHODS A retrospective analysis of 21,115 hospital-days of 715(More)
Nonrandom ascertainment is commonly used in genetic studies of rare diseases, since this design is often more convenient than the random-sampling design. When there is an underlying latent heterogeneity, Epstein et al. ([2002] Am. J. Hum. Genet. 70:886-895) showed that it is possible to get unbiased or consistent estimation of population parameters under(More)
OBJECTIVES A hierarchical generalized linear model (HGLM) was applied to estimate the transmission pattern of scrub typhus from 2001 to 2011 in the Republic of Korea, based on spatial and temporal correlation. METHODS Based on the descriptive statistics of scrub typhus incidence from 2001 to 2011 reported to the Korean Centers for Disease Control and(More)
Understanding causes of hospital closure is important if hospitals are to survive and continue to fulfill their missions as the center for health care in their neighborhoods. Knowing which hospitals are most susceptible to closure can be of great use for hospital administrators and others interested in hospital performance. Although prior studies have(More)
BACKGROUND This study aimed to examine whether the socioeconomic context of urban areas affects differences in adult mortality from injuries in the districts of all seven South Korean metropolitan cities, after adjusting for individual demographic and socioeconomic indicators. METHODS Two different sets of data were used in this study: (1) the National(More)
In medical research recurrent event times can be analysed using a frailty model in which the frailties for different individuals are independent and identically distributed. However, such a homogeneous assumption about frailties could sometimes be suspect. For modelling heterogeneity in frailties we describe dispersion frailty models arising from a new(More)
