The mechanism of electroconvulsive therapy (ECT) in schizophrenia remains unclear, with limited research available. Previous studies have reported ECT-induced changes in protein markers, including neurotrophic factors, inflammatory markers, and signaling proteins, but findings have been inconsistent. This study reviews existing literature on protein changes associated with ECT and explores potential molecular mechanisms underlying its effects. Additionally, we present pilot findings from 34 patients with schizophrenia or schizoaffective disorder who underwent ECT at Seoul National University Hospital. Blood samples collected before and after ECT were analyzed via liquid chromatography-tandem mass spectrometry (LC-MS/MS) to identify differentially expressed proteins (DEPs), with Pearson’s correlation analysis examining their association with symptom changes. Talin 2 emerged as a potential biomarker linked to clinical improvement. However, given the small sample size, these findings require cautious interpretation. Further research is needed to clarify the molecular mechanisms underlying ECT’s therapeutic effects in schizophrenia.

Despite hearing loss being a prevalent chronic condition, estimated to nearly 20% of the global population by the World Health Organization, the specific association with individual lifestyle factors, particularly alcohol consumption, remains unclear. In South Korea, approximately 80% of the population engages in alcohol consumption, with a notably high prevalence among males, indicating a high-risk drinking pattern. Therefore, this study aimed to assess the correlation between alcohol consumption and hearing loss in male workers, as well as to analyze additional variables such as alcohol flushing reaction, with the intention of improving worker health. The study was conducted from January 2012 to December 2019, targeting 114,114 participants who visited Kangbuk Samsung Hospital Total Healthcare Centers. Data were collected through pure-tone audiometry tests and alcohol-related questionnaire, and statistical analysis was performed using Cox regression analysis. Based on previous studies indicating a potential protective effect of light drinking on hearing loss, this group was designated as the reference. Additionally, stratified analyses were conducted based on the presence of alcohol flushing reaction and different working hours. The hazard ratio (95% confidence interval) for hearing loss was higher in the heavy drinking group (1.23 [1.11–1.37]) compared to the moderate drinking group (1.09 [0.98–1.20]). Stratified analyses revealed a significantly elevated the hazard ratio of hearing loss in groups with alcohol flushing reaction compared to those without this factor. Our study demonstrated that moderate or heavy alcohol consumption in male workers can increase the risk of hearing loss, particularly in those with alcohol flushing reaction. These findings underscore the importance of addressing alcohol-related factors concerning hearing health among male workers.
