BACKGROUND A systematic literature review of interspinous dynamic stabilization, including DIAM, Wallis, Coflex, and X-STOP, was conducted to assess its safety and efficacy. METHODS The search was done in Korean and English, by using eight domestic databases which included KoreaMed and international databases, such as Ovid Medline, Embase, and the(More)
BACKGROUND/AIMS We made a systematic review and evaluation of endoscopic cryotherapy of endobronchial tumors, investigating safety and efficacy. METHODS Qualified studies regarding endoscopic cryotherapy of lung tumors were systemically evaluated using available databases according to predefined criteria. RESULTS In total, 16 publications were included(More)
Copeptin, the C-terminal part of provasopressin, has emerged as a novel prognostic marker after hemorrhagic or ischemic stroke. The aim of this study was to quantitatively assess the prognostic significance of plasma copeptin level on functional outcome and mortality in patients with acute stroke using a meta-analysis of the available evidence. Thirteen(More)
BACKGROUND Numerous previous studies have shown that individual socioeconomic status (SES) is associated with mortality in patients with chronic obstructive pulmonary disease (COPD), but few empirical studies have evaluated the effects of individual SES and neighborhood deprivation on mortality in COPD patients. METHODS We performed a prospective cohort(More)
To make an optimal treatment decision for early stage breast cancer, it is important to identify risk of recurrence. Here, we developed and validated a new prognostic model for predicting the risk of distant metastasis in patients with pN0-N1, hormone receptor-positive, HER2-negative (HR+/HER2-) breast cancer treated with hormone therapy alone. RNA was(More)
BACKGROUND Previous studies have shown that contextual factors and individual socioeconomic status (SES) were associated with mortality in Western developed countries. In Korea, there are few empirical studies that have evaluated the association between SES and health outcomes. METHODS We conducted cohort study to investigate the socioeconomic disparity(More)
OBJECTIVE To determine whether patients with greater continuity of care (COC) have fewer preventable hospitalizations. DESIGN We conducted a cohort study using a stratified random sample of Korean National Health Insurance enrollees from 2002 to 2010. The COC index was calculated for each year post-diagnosis based on ambulatory care visits. We performed a(More)
BACKGROUND Ambulatory care-sensitive conditions, including asthma, can be managed with timely and effective outpatient care, thereby reducing the need for hospitalization. OBJECTIVE This study assessed the relationship between market competition, continuity of care (COC), and hospital admissions in asthmatic children according to their health care(More)
We aimed to quantitatively assess the effects of short-term statin use on delayed ischemic neurologic deficits (DINDs) and clinical outcomes in patients with aneurysmal subarachnoid hemorrhage (SAH) through a meta-analysis of the available evidence. We searched the electronic databases up to April 8, 2016 to retrieve relevant studies comparing the outcomes(More)
OBJECTIVES Asia sand dust (ASD) is known to cause various human diseases including respiratory infection. The aim of this study was to examine the effect of ASD on inflammatory response in human middle ear epithelial cells (HMEECs) in vitro and in vivo. METHODS Cell viability was assessed using the cell counting kit-8 assay. The mRNA levels of various(More)
