This study investigated work experience of firefighters and risk factors for their depression during COVID-19 pandemic. We analyzed data of 53,557 firefighters who participated in the online mental health status survey. Data included experiences of COVID-19 infection, experience of COVID-19 response work, fear of social stigma, and anxiety and depression symptoms. Results showed that 45.76% of participants had experience of COVID-19 response work. Emergency job group had the highest percentage of COVID-19 related work and the greater intensity of the work and fear of social stigma than those of other job groups. Hierarchical multiple regression showed that co-workers' infection, COVID-19 related work intensity and fear of social stigma were significantly associated to the severity of depression. The findings in this study demonstrated COVID-19 related work experience can link to the development of depression in firefighters. Effort to reduce COVID-19 related work intensity and fear of social stigma could help prevent depression among firefighters.

The number of depressed patients in Korea and around the world is rapidly increasing every year. However, most of the mentally ill patients are not aware that they are suffering from the disease, so adequate treatment is not being performed. If depressive symptoms are neglected, it can lead to suicide, anxiety, and other psychological problems. Therefore, early detection and treatment of depression are very important in improving mental health. To improve this problem, this study presented a deep learning-based depression tendency model using Korean social media text. After collecting data from Naver KonwledgeiN, Naver Blog, Hidoc, and Twitter, DSM-5 major depressive disorder diagnosis criteria were used to classify and annotate classes according to the number of depressive symptoms. Afterwards, TF-IDF analysis and simultaneous word analysis were performed to examine the characteristics of each class of the corpus constructed. In addition, word embedding, dictionary-based sentiment analysis, and LDA topic modeling were performed to generate a depression tendency classification model using various text features. Through this, the embedded text, sentiment score, and topic number for each document were calculated and used as text features. As a result, it was confirmed that the highest accuracy rate of 83.28% was achieved when the depression tendency was classified based on the KorBERT algorithm by combining both the emotional score and the topic of the document with the embedded text. This study establishes a classification model for Korean depression trends with improved performance using various text features, and detects potential depressive patients early among Korean online community users, enabling rapid treatment and prevention, thereby enabling the mental health of Korean society. It is significant in that it can help in promotion.

Due to the high population prevalence of major depression and the strong emphasis on pharmacotherapy for this disorder, antidepressants are among the most frequently prescribed pharmacological agents. But the clinicians are still unable to predict accurately the response of their depressed patients to medication. This article reviews the biological predictors of treatment response including monoamine, neuroendocrine, pharmacogenetic, and psychophysiologic markers. The biological predictors of response, despite some interesting leads that may in the long term be of considerable importance, are not yet sufficiently established to be of routine clinical usefulness. Many of the predictive factors explored in this article are examples of mediators and moderators that affect outcomes. Each one alone may not provide definitive answers for predicting response to treatment, but each must be taken into account at the outset of treatment. It is clear that treatments must be individualized for each patient. It would be necessary to develop the algorithm in order to predict the responsiveness of antidepressant treatment with integration of the results from the previous studies.

Recent studies have shown that insufficient or deficient vitamin D status may be linked to increased risk of depressive conditions or depression. The aim of this study was to review all available evidence on vitamin D, depression, and any association between them. Cross-sectional, case-control, and cohort studies have reported contradictory results. Some have reported that low levels of vitamin D may be associated with higher risk of depression or depressive symptoms while others reported that vitamin D status may not be related to depression. Recent clinical trials examining the effects of vitamin D supplementation on depression have also showed discrepant results. However, meta-analysis study results are consistent regarding the beneficial effects of vitamin D. Several mechanisms that account for these beneficial effects of vitamin D on depression have been reported but remain largely speculative. Vitamin D deficiency is very common, and prevalence of depression is increasing in the Asian population, especially females. However, limited literature is available on this population. Considering research results of a potential inverse association between vitamin D level and prevalence of depression, it is important to advance our understanding of the role of vitamin D in depression and conduct well-designed prospective trials in the Asian population.

A 49-year-old male was found unconscious at his accommodation and visited the emergency room. He was on antipsychotic and antidepressant drugs (vortioxetine hydrobromide, mirtazapine, sertraline hydrochloride, quetiapine, and alprazolam) for schizophrenia and major depression. At the time of discovery there were signs of overdose of the drugs around the patient. A physical examination revealed, pain, pallor, and edema in the left buttocks and lateral thigh. Active ankle movements below the left ankle were not possible and sensations in the tibia and peroneal nerves were lost. The pressure in the buttock compartment was measured at 42 mmHg. Magnetic resonance imaging revealed edema and high intensity signals in the left hip muscles and surrounding soft tissue. An emergency fasciotomy was performed and partial restoration of the lower extremity sensation and muscle strength were achieved after 24 hours.

Purpose: Depression is a prevalent mental health concern globally including South Korea. Given the growing interest in the relationship between diet and mental health, this study aimed to investigate the association between seafood consumption and depression among Korean adults. Methods: A cross-sectional analysis was conducted using data from the Korea National Health and Nutrition Examination Survey (KNHANES, 2014-2020). The study included 18,149 participants (7,541 men and 10,608 women) aged 19 years and older who completed the Patient Health Questionnaire (PHQ-9). Seafood intake levels were assessed using a oneday 24-hour dietary recall, and participants were categorized into three tertiles by gender. Depression status was determined using the PHQ-9 scores and the self-report of the doctor's diagnosis and treatment. Multivariable logistic regression analysis was performed to assess the association between seafood consumption and depression in both genders. Results: Participants with a higher seafood intake had a significantly lower nutritional density of total fat, while the nutritional density of omega-3 polyunsaturated fatty acids was significantly higher. The prevalence of depression was significantly lower in the highest tertile of seafood consumption compared to the lowest tertile in both men (p < 0.001) and women (p < 0.001). After adjusting for confounding factors, the highest tertile of seafood consumption demonstrated a decreased risk of depression compared to the lowest tertile in men (odds ratio [OR], 0.71; 95% confidence interval [CI], 0.51-0.99; p-trend = 0.020) and women (OR, 0.73; 95% CI, 0.59-0.91; p-trend = 0.004). Conclusion: The findings of this study suggest that consuming seafood rich in omega-3 fatty acids may potentially reduce the risk of depression in the adult population.

The purpose of this study was to analyze the risk factors of depression in elementary school students in Korea. The subjects of the study were 23,291 elementary school students (12,016 male, 11,275 female) aged 9 to 12 years. Dependent variable was defined as experience of depression. Explanatory variables were included as sex, residential areas, social discrimination experience, experience of school violence for the past year, experience of Korean language education, experience of using multicultural family support center, reading to Korean, speaking to Korean, and writing to Korean, listening to Korean. In the RBF neural network analysis, experience of Korean education, experience of school violence, experience of Korean social discrimination, level of Korean reading were significantly associated with depression in elementary school students. In order to prevent depression in multicultural children, priority attention and counseling are needed for the group whose level of Korean reading is low.

This study was undertaken to investigate the influence and related mechanisms that have yet to be clearly demonstrated of Lithospermum erythrorhizon derived-naphthoquinone (shikonin) on the anxiety, insomnia, depression in rats. We hypothesized that naphthoquinone, the primary ingredient of Lithospermum erythrorhizon, plays a role in the modulation of insomnia evoked by stress, depression evoked by forced swimming or anxiety evoked by elevated plus maze. Male ICR (Institute of Cancer Research) mice were used and the immobility or swimming time, the duration of sleep, the duration and entry frequency into open arms were measured and recorded. The administration of naphthoquinone (10, 30 and 100 mg/kg) potentiated barbiturate-induced sleep suggesting the activation of GABAA receptor. It also potentiated the time spent in open arms of the maze and decreased the immobility time in forced swimming. In conclusion, naphthoquinone has anxiolytic, hypnotic and anti-depressant properties and is a potential therapeutic for anxiety, insomnia and depression.

This review aims to propose a model that can reinterpret the abnormal and functional connections between cognitive processes and emotional regulations based on the neurocognitive networks for a comprehensive understanding of pathologic processes and treatment approach of depression and anxiety disorder. Through the processes of rebuilding the network model for depression and anxiety disorder, it was confirmed that depression can be said to be 'over-immersion in self-referencing' due to hyper-activation of default mode network (DMN), and anxiety disorders to be 'disconnection with self-referencing' due to hypo-activation of DMN. The attempts to link up between abnormal activation and pathological function of DMN which is thought to be involved in self-referential processing associated with self-consciousness and projection among neurocognitive networks may be another starting point that can afford to be suggestive in integrated interpretation and therapeutic approach to depression and anxiety disorder.
