OBJECTIVE: The aim of this study was to examine the reliability and validity of the Korean version of the Impaired Control Scale (K-ICS), a scale to screen patients with alcohol use disorder. METHODS: Participants were 173 inpatients with alcohol use disorder (AUD), and 174 normal controls (NC). Both AUD and NC groups completed the K-ICS as well as the Alcohol Dependence Scale (ADS), the Alcohol Abstinence Self-Efficacy Scale (AASES), the Brief Self-Control Scale (BSCS), and the Hospital Anxiety and Depression Scale (HAD). RESULTS: The internal consistencies of K-ICS were good in both AUD and NC. A good convergent validity was clearly shown by significant correlations with the ADS and the AASES, respectively. But the K-ICS had no or weak correlations with the BSCS and the HAD. The ROC curve analyses indicated that the optimal cut-off points of failed control (FC) and predicted control (PC) were estimated as >15 and >13, respectively. Hierarchical multiple regression analysis suggested that FC is a robust predictor of the severity of AUD. CONCLUSION: The K-ICS, especially FC subscale of it appears to be a valid and reliable measure of impaired control among both clinical and non-clinical sample.

OBJECTIVE: The aim of this study was to examine the efficacy of the life goal-focused brief intervention, or the so-called the goal-focused self-regulation program (GFSRP), for patients with alcohol use disorder (AUD). METHODS: The GFSRP was developed as an 8-week group-program, which is based on a wide range of self-regulation theories, such as goal setting and implementation intentions. Patients with AUD (n=50) took part in the GFSRP and were compared to the control group (n=48). This study examined the changes in outcome measures from baseline to follow-up (12-week) in a mixed design. RESULTS: The GFSRP group had higher scores for the abstinence self-efficacy in negative affect situations than the control group at the post-test. In addition, it showed greater scores of optimisms compared to the control group. Furthermore, in the GFSRP group, there was no difference in intrinsic life goals from baseline to the 12-week follow-up, whereas the control group showed a significant decrease. CONCLUSION: The GFSRP could increase the abstinence self-efficacy and optimism among patients with AUD. Moreover, it might prevent loss of life-goals as core factors in self-regulation among patients with AUD.

OBJECTIVES: Previous epidemiological studies about oxidative stress and depression are limited by hospital-based case-control design, single-time measurements of oxidative stress biomarkers, and the small number of study participants. Therefore, in this study, we analyzed the association between biomarker of oxidative stress and depressive symptom scores using repeatedly measured panel data from a community-dwelling elderly population. METHODS: From 2008 to 2010, a total of 478 elderly participants residing in Seoul, Korea, were evaluated three times. Participants underwent the Korean version of the Short Form Generic Depression Scale (SGDS-K) test for screening depression, and urinary malondialdehyde (MDA) levels were measured as an oxidative stress biomarker. We used a generalized estimating equation with a compound symmetry covariance structure to estimate the effects of oxidative stress on depressive symptom scores. RESULTS: A two-fold increase in urinary MDA concentration was significantly associated with a 33.88% (95% confidence interval [CI], 21.59% to 47.42%) increase in total SGDS-K scores. In subgroup analyses by gender, a two-fold increase in urinary MDA concentration was significantly associated with increased SGDS-K scores in both men and women (men: 30.88%; 95% CI, 10.24% to 55.37%; women: 34.77%; 95% CI, 20.09% to 51.25%). In bivariate analysis after an SGDS-K score ≥8 was defined as depression, the third and the fourth urinary MDA quartiles showed a significantly increased odds ratio(OR) of depression compared to the lowest urinary MDA quartile (third quartile OR, 6.51; 95% CI, 1.77 to 24.00; fourth quartile OR, 7.11; 95% CI, 1.99 to 25.42). CONCLUSIONS: Our study suggests a significant association between oxidative stress and depressive symptoms in the elderly population.

OBJECTIVES: The second to fourth digit ratio (2D : 4D) is known to reflect testosterone level during intrauterine period. Testosterone is essential for masculinization of brain. Cloninger's type II alcoholism is characterized by early age at onset and largely limited to males. Compared with type I alcoholism, type II alcoholism is thought to be masculine. There is a possibility that the digit ratio of type II alcoholism is low compared with type I. We examined digit length ratio in Cloninger's type I and II alcoholism to understand the effects of intrauterine testosterone on the development of alcoholism. METHODS: The participants were 87 alcohol dependent patients. We divided two subtypes of patients by Irwin's symptom list, based on Cloninger's concept. We captured the images of both palms by the scanner and measured the lengths of digits by the graphic program. Then we analyzed the digit ratios by independent-sample t-test. RESULTS: The mean 2D : 4D of type I was 0.942 (right), 0.952 (left). The mean 2D : 4D of type II was 0.927 (right), 0.940 (left). In both hands, 2D : 4D of type II was significantly lower than type I. CONCLUSIONS: Type II alcoholism showed masculine type of digit length ratio compared with type I. It suggests the exposure of testosterone during intrauterine period might play an important role in determining the course and feature of alcoholism.

Objective: The ratio of 2nd and 4th digit length (2D:4D) is considered to be a sexually dimorphic trait. Low 2D:4D is implicated in alcohol dependence and heroin dependence and correlated with psychological traits such as aggression, physical aggression, and sensation. The purpose of this study is to compare the 2D:4D between methamphetamine (METH) dependence and controls and the 2D:4D ratio that is a potential biomarker for METH dependence. Methods: In this study, 40 patients diagnosed with METH dependence in Eulji University Gangnam Eulji Hospital and 50 healthy volunteers were all employees in the same hospital. Images of participants’ hands were created using a scanning device. The images contained both the right and left hands; computer software was used to measure the 2D:4D ratio for both hands. We compared the ratios, analyzed by t test, between the METH dependence group and the control group. Results: The mean 2D:4D values were 0.941 (right hand) and 0.943 (left hand) for the patients with METH dependence; in contrast, they were 0.961 (right hand) and 0.961 (left hand) for the control group. These values were significantly smaller than the control in patients’ right hands (p = 0.003) and left hands (p = 0.012). Conclusion Patients with METH dependence had smaller 2D:4D ratios than those in the control group, which is similar to the results from the previous substance use disorder studies. Thus, elevated prenatal testosterone levels during the gonadal period could be related to future METH problems. Furthermore, the 2D:4D ratio is a potential marker for the prediction of METH dependence.

OBJECTIVE: The ratio of 2nd to 4th digit length (2D:4D) is a sexually dimorphic trait. Men have a relatively shorter second digit than fourth digit. This ratio is thought to be influenced by higher prenatal testosterone level or greater sensitivity to androgen. The purpose of this study is to investigate the relationship between alcohol dependence and 2D:4D in a Korean sample and whether 2D:4D can be a biologic marker in alcohol dependence. METHODS: In this study, we recruited 87 male patients with alcohol dependence from the alcohol center of one psychiatric hospital and 52 healthy male volunteers who were all employees in the same hospital as controls. We captured images of the right and left hands of patients and controls using a scanner and extracted data with a graphics program. We measured the 2D:4D of each hand and compared the alcohol dependence group with the control group. We analyzed these ratios using an independent-samples t-test. RESULTS: The mean 2D:4D of patients was 0.934 (right hand) and 0.942 (left hand), while the mean 2D:4D of controls was 0.956 (right hand) and 0.958 (left hand). Values for both hands were significantly lower for patients than controls (p<0.001, right hand; p=0.004, left hand). CONCLUSION: Patients who are alcohol dependent have a significantly lower 2D:4D than controls, similar to the results of previous studies, which suggest that a higher prenatal testosterone level in the gonadal period is related to alcoholism. Furthermore, 2D:4D is a possible predictive marker of alcohol dependence.

OBJECTIVES: Delirium is commonly seen in clinical settings, and it can substantially influence the prognosis of patients. In this study, we investigated delirium with respect to its severity, classification and characteristics on each subtype. METHODS: Severity of delirium was examined in delirium patients, who were referred to the department of psychiatry in a general hospital for multidisciplinary treatment. After classification based on subtypes, factors influencing these aspects of delirium were examined. RESULTS: Among the 193 consultation-liaison patients referred to the department of psychiatry in a general hospital, 61 patients (31.6%) were diagnosed with delirium. Compared to patients in the non-delirium group, patients in the delirium group were older, had a shorter education period, and medical history of surgery. Among the delirium patients, the hyperactive subtype was found to be the most common (57.4%) and patients with the mixed subtype showed the highest severity score for delirium symptoms. In addition, the patient with the hypoactive subtype had a higher frequency of medical history of depression compared to those with the other subtypes. CONCLUSION: People with symptoms of hypoactive delirium can be misdiagnosed due to recurrence of depression, therefore, careful examination is required, particularly in patients with a history of depression.

OBJECTIVE: This study aims to reveal the relationship of depression with growth factors such as brain-derived neurotrophic factor (BDNF), nerve growth factor (NGF), and insulin-like growth factor-1 (IGF-1) in inpatients diagnosed with alcohol dependence, and to identify candidate growth factors as biological markers to indicate the comorbid of alcohol dependence and depression. METHODS: This study examined demographic factors in 45 alcohol-dependent patients. The ADS (Korean version of the Alcohol Dependence Scale) and BDI (Korean version of Beck's Depression Inventory) were used. BDNF, NGF, and IGF-1 were measured through ELISA. RESULTS: The average drinking quantity and the ADS score were significantly more severe in alcohol-dependent patients with depression than in those without depression. Linearly comparing BDNF, NGF, and IGF-1 with BDI values, IGF-1 was the growth factor significantly correlated with BDI scores. BDI scores were significantly correlated with ADS scores. IGF-1 was significantly higher in alcohol-dependent patients with depression. Alcohol-dependent patients with depression had greater alcohol use and more severe ADS scores. BDNF and NGF showed no significant difference between alcohol-dependent patients with and without depression, but IGF-1 was significantly higher in those with than in those without depression. CONCLUSION: IGF-1 was found to be associated with depression in alcohol-dependent patients, suggesting that IGF-1 in alcohol-dependent patients could be an important biomarker to indicate whether alcohol-dependence is accompanied by depression.

BACKGROUND: The current study evaluated the hospital utilization and characteristics of patients who received health care services for acute cerebral infarction outside their own residential area. METHODS: Using the 2014 national patient survey data, information on 2,982 patients diagnosed with acute cerebral infarction through emergency department were retrieved for the analyses. Multiple logistic regression was performed to investigate the characteristics associated with using hospitals outside residential area among patients diagnosed with acute cerebral infarction. RESULTS: Fifteen point nine percent of patients admitted for acute cerebral infarction utilized hospitals outside their residential area. Patients residing in a province were 7.7 times more likely to utilize hospitals located outside their residential areas compared to those living in Seoul metropolitan city. Patients living in Gangwon and Jeolla were 0.26 times and 0.48 times more likely to go to hospitals in different geographical areas. Also, patients within the age group of 80 years and over were 0.65 times less likely to be admitted to hospitals outside their residential area compared to those in their 40s–50s. CONCLUSION: The use of hospitals outside patient's residential area is shown to be substantial, given that the acute cerebral infarction requires immediate recognition and treatment. The findings on the geographical differences in the hospital utilization suggest further investigation.
