BACKGROUND: An alpha2-adrenergic receptor (alpha2-AR, ADRA2) mediates induction of hypotension and inhibition of lipolysis and insulin secretion. We evaluated whether single nucleotide polymorphisms (SNPs) of alpha2A (ADRA2A), alpha2B (ADRA2B), and alpha2C (ADRA2C) adrenergic receptors are associated with cerebral white matter lesion (cWML). METHODS: Total 336 study subjects who had no stroke were enrolled in this study. The Indices of cWML include total WML (TWML), periventricular WML (PVWML), and subcortical WML (SCWML) on brain fluid-attenuated inversion recovery (FLAIR) image. Common genetic variants of ADRA2A (1780G>A), ADRA2B (Ins/Del301-303), and ADRA2C (Ins/Del322-325) were examined. RESULTS: Among 336 study subjects, cWML was found in 66 patients (20%). In multivariate analysis, there were no significant effects of all tested ADRA2 polymorphisms on TWML. Significant association of ADRA2A 1780 AA genotype was found in PVWML (OR: 3.368, 95% CIs: 1.280-8.865, adjusted p-value after false discovery rate (FDR) correction=0.014) but not SCWML. CONCLUSION: Although SNPs of three ADRA2 subtypes failed to reach a significance in overall risk for cWML, the ADRA2A 1780G>A polymorphism may be associated with development of PVWML.

OBJECTIVES: Sexual assaults are increasing in the world. They are frequently associated with violence of verbal or physical force and threat. The aim of this study is to investigate frequency of violence according to characteristics of sexual assault. METHODS: Eighty two female sexual assault victims were referred to the psychiatric clinic from Gwangju One-Stop Service Center between Sep. 4, 2006 and Dec. 31, 2012. We compared the frequency of violence, including verbal or physical force and threat according to characteristics of sexual assault : sexual assault type ; relationship with perpetrator ; time lag to visit one-stop center ; assault location. RESULTS: According to the results, 58.5% (n=48) of subjects had experienced violence before the sexual assaults. Compared to rape (50.9%), indecent (76.0%) showed more frequent violence ; and stranger assailant (81.8%) showed greater frequency of violence than acquaintance (50.0%). Victims who visited the One-stop center within 24 hours (76.7%) had greater exposure to violence than those who visited after 24 hours (48.1%). Regarding assault location, violence frequency was higher in other locations (65.7%) than in accommodations (26.7%). CONCLUSION: Our results suggest that frequency of violence before sexual assaults could be influenced by their characteristics.

Objective: No studies have evaluated the diagnostic value of ischemia-modified albumin (IMA) for the early detection of sepsis/septic shock in patients presenting to the emergency department (ED). We aimed to assess the usefulness of IMA in diagnosing sepsis/septic shock in the ED. Methods: This retrospective, observational study analyzed IMA, lactate, high sensitivity C-reactive protein, and procalcitonin levels measured within 1 hour of ED arrival. Patients with suspected infection meeting at least two systemic inflammatory response syndrome criteria were included and classified into the infection, sepsis, and septic shock groups using Sepsis-3 definitions. Areas under the receiver operating characteristic curves (AUCs) with 95% confidence intervals (CIs) and multivariate logistic regression were used to determine diagnostic performance. Results: This study included 300 adult patients. The AUC (95% CI) of IMA levels (cut-off ≥85.5 U/mL vs. ≥87.5 U/mL) was higher for the diagnosis of sepsis than for that of septic shock (0.729 [0.667–0.791] vs. 0.681 [0.613–0.824]) and was higher than the AUC of procalcitonin levels (cut-off ≥1.58 ng/mL, 0.678 [0.613–0.742]) for the diagnosis of sepsis. When IMA and lactate levels were combined, the AUCs were 0.815 (0.762–0.867) and 0.806 (0.754–0.858) for the diagnosis of sepsis and septic shock, respectively. IMA levels independently predicted sepsis (odds ratio, 1.05; 95% CI, 1.00–1.09; P=0.029) and septic shock (odds ratio, 1.07; 95% CI, 1.02–1.11; P=0.002). Conclusion Our findings indicate that IMA levels are a useful biomarker for diagnosing sepsis/ septic shock early, and their combination with lactate levels can enhance the predictive power for early diagnosis of sepsis/septic shock in the ED.

BACKGROUND: Comprehensive geriatric assessment is identified as a dynamic process responsive to the changes on health status that occurs over time in the context of extremely increasing trend in the numbers of the elderly people, their office visit, and the medical cost universally. We completed the comprehensive geriatric assessment and applied it to the Korean elderly through the multi-center trials. METHODS: We performed studies variables using questionnaires, with interviewing, physical examination to the number of total 312 elderly people who visited the department of family medicine or physical medicine and rehabilitation of the 11 university hospital or general hospital in Korea from July 1, 1999 through October 31, 1999. We, the geriatrician, met and discussed 3 times to complete the comprehensive geriatric assessment through the consensus panel. RESULTS: We found the sex ratio of 312 subjects was 1 to 2 (104 males and 208 females) and the average age was 73.2 years old. The orders of more frequency of self-reported health status of the respondents were hypertension, arthritis, cataract, gastrointestinal disturbance, diabetes mellitus, urinary/fecal incontinence, depression, cerebrovascular accident, anemia, and heart disease. Nearly 15% of those showed depression, 41.6% of those were in the status of socially isolation. We found 43.1% of those showed hypertension, 3.7% isolated systolic hypertension, and 20.2% orthostatic hypotension. Of those, cognitive impairment were measured in 37.1%, gait disturbance 13.0%, and the risk of malnutrition 39.6%. Geriatrician spent 21.1 minutes per person during the process of comprehensive geriatric assessment. CONCLUSION: We realized we could diagnose and intervene effectively certain hidden conditions/diseases, particularly urinary incontinence, falls, visual impairment, hearing impairment, pain, depression, social isolation, cognitive impairment, and orthostatic hypotension, with using the comprehensive geriatric assessment. These results reflected the fact that the comprehensive geriatric assessment might be necessary for the care of the elderly.

The pneumonia severity index (PSI) and CURB-65 are widely used tools for the prediction of community-acquired pneumonia (CAP). This study was conducted to evaluate validation of severity scoring system including the PSI and CURB-65 scores of Korean CAP patients. In the prospective CAP cohort (participated in by 14 hospitals in Korea from January 2009 to September 2011), 883 patients aged over 18 yr were studied. The 30-day mortalities of all patients were calculated with their PSI index classes and CURB scores. The overall mortality rate was 4.5% (40/883). The mortality rates per CURB-65 score were as follows: score 0, 2.3% (6/260); score 1, 4.0% (12/300); score 2, 6.0% (13/216); score 3, 5.7% (5/88); score 4, 23.5% (4/17); and score 5, 0% (0/2). Mortality rate with PSI risk class were as follows: I, 2.3% (4/174); II, 2.7% (5/182); III, 2.3% (5/213); IV, 4.5% (11/245); and V, 21.7% (15/69). The subgroup mortality rate of Korean CAP patients varies based on the severity scores and CURB-65 is more valid for the lower scores, and PSI, for the higher scores. Thus, these variations must be considered when using PSI and CURB-65 for CAP in Korean patients.
