OBJECTIVES: The individual's ability to recognize and describe emotion in self and others is an important concept of many psychiatric disorders. The purpose of this study was to investigate emotional awareness deficits in patients with alcohol dependence. METHODS: 55 male inpatients with alcohol dependence and 28 male normal controls were evaluated by the Korean version of the Levels of Emotional Awareness Scale (LEAS-K), the Korean version of the 20-item Toronto Alexithymia Scale (TAS-20K), the Openness Experience Inventory (OEI) and the Beck Depression Inventory (BDI). The LEAS-K is an objective measure to assess the ability to be aware of one's own or another's emotions and the TAS-20 is the most widely used subjective measure of alexithymia. Scores of these scales were compared between two groups using ANCOVA controlling age and BDI scores. RESULTS: The LEAS-K scores were significantly lower in alcohol-dependent patients than normal controls. The TAS-20K total scores, factor 1 (Difficulty to Identifying Feeling, DIF) and factor 3 (Externally Oriented Thinking, EOT) were significantly higher in alcohol-dependent patients than normal controls. In contrast to the LEAS-K, the TAS-20K scores correlated significantly with the BDI scores. CONCLUSION: Emotional awareness is impaired in alcohol-dependent patients and it may not be related with depressive mood. Additional studies are needed to explore the significance of alexithymia, especially impaired emotional awareness, and its relationship to depressive mood in patients with alcohol dependence.

Background:
Since 2013, the number of requests for diagnosis for horses based on neurological symptoms has increased rapidly in South Korea. The affected horses have commonly exhibited symptoms of acute seasonal hindlimb ataxia. A previous study from 2015–2016 identified Setaria digitata as the causative agent.
Objectives:
This study is an epidemiological investigation to find out risk factors related to the rapid increase in hindlimb ataxia of horses due to aberrant parasites in South Korea.
Methods:
An epidemiological investigation was conducted on 155 cohabiting horses in 41 horse ranches where the disease occurred. The surrounding environment was investigated at the disease-causing horse ranches (n = 41) and 20, randomly selected, non-infected ranches.
Results:
Hindlimb ataxia was confirmed in nine cohabiting horses; this was presumed to be caused by ectopic parasitism. Environments that mosquitoes inhabit, such as paddy fields within 2 km and less than 0.5 km from a river, had the greatest association with disease occurrence.
Conclusions
Most horse ranches in South Korea are situated in favorable environments for mosquitoes. Moreover, the number of mosquitoes in the country has increased since 2013 due to climate change. Additional research is required; however, these data show that it is necessary to establish guidelines for the use of anthelmintic agents based on local factors in South Korea and disinfection of the environment to prevent disease outbreaks.

Background:
Limited data are available on hepatitis C virus (HCV) infection in persons who inject drugs (PWID) in South Korea. The present study aimed to investigate the seroprevalence of HCV antibodies, risk factors for HCV seropositivity, and HCV treatment status in PWID between January 2012 and May 2022.
Methods:
We retrospectively reviewed the medical records of 418 drug users who underwent HCV antibody testing in three hospitals caring for 90% of known PWID in South Korea, of whom 373 were PWID.
Results:
The HCV seroprevalence was 39.7% (148/373) in PWID vs. 6.7% (3/45) in noninjection drug users (P < 0.001). Age ≥ 40 years, hospital type (58.2% in the prison hospital vs. 34.0% in the private hospital), and enrollment year (68.2% in 2012–2014 vs. 30.0% in 2021–2022) were independently associated with HCV seropositivity. Among the HCVseropositive PWID, 90.5% (134/148) were diagnosed with HCV infection; however, only 6.8% (10/148) received HCV treatment. The hepatitis B virus surface antigen and human immunodeficiency virus antibody positivity were 4.0% (14/352) and 1.9% (6/317) in tested PWID, respectively.
Conclusion
The HCV seroprevalence in PWID was 39.7% with a very low treatment rate, which prompts active measures to test and treat PWID for HCV infection in South Korea.
