New Intervention Model of Regional Transfer Network System to Alleviate Crowding of Regional Emergency Medical Center.
Emergency department (ED) crowding is a serious problem in most tertiary hospitals in Korea. Although several intervention models have been established to alleviate ED crowding, they are limited to a single hospital-based approach. This study was conducted to determine whether the new regional intervention model could alleviate ED crowding in a regional emergency medical center. ⋯ We found that the median ED length of stay (LOS) decreased significantly from 3.68 hours (interquartile range [IQR], 1.85 to 9.73) to 3.20 hours (IQR, 1.62 to 8.33) in the patient group after implementation of the Regional Transfer Network System (RTNS) (P < 0.001). The results of multivariate analysis showed a negative association between implementation of the RTNS and ED LOS (beta coefficient -0.743; 95% confidence interval -0.914 to -0.572; P < 0.001). In conclusion, the ED LOS in the tertiary hospital decreased after implementation of the RTNS.

Impact of Childbearing Decisions on Family Size of Korean Women with Systemic Lupus Erythematosus.
Systemic lupus erythematosus (SLE) predominantly affects women in their reproductive years and has a significant impact on childbearing. We investigated the influence of personal decision on family size among Korean women with SLE and factors that affect the decisions. A case-control study comparing childbearing history and decisions of 112 SLE patients and 135 controls was performed. ⋯ Significantly more women with SLE made the decision not to have children compared with controls (54.5% vs. 40.7%, P = 0.031), and health-related concerns were the major cause of the decision. Other socio-demographic factors did not influence the decision to limit childbearing in SLE women. The disease-related concerns had significant impact on family size and childbearing decisions among Korean women with SLE.

The Effects of Alcohol on Visual Evoked Potential and Multifocal Electroretinography.
The aim of this study was to investigate the acute effects of ethanol administration on pattern-reversal visual evoked potential (VEP) and multifocal electroretinography (mfERG). Fifteen healthy subjects with no ocular or general disease were recruited. VEP (0.25° pattern sizes) and mfERG with 19 elements in two recording segments were performed before ethanol administration to obtain baseline for each participant. ⋯ The P1 implicit time of ring 1 on mfERG showed a trend of shortening after alcohol administration (37.9 ± 1.0; 37.2 ± 1.5; P = 0.048). However, the changes did not show statistical significance after Bonferroni correction. In conclusion, orally administrated ethanol (0.75 g/kg) appears to suppress the central nervous system, but it is not clear whether alcohol intake affects the retina.
