Objectives: This study was undertaken to explore correlations between depression, alcohol drinking, psychiatric symptoms, and suicidal ideation, and to identify factors related to suicidal ideation in the mentally ill. Methods: A survey was conducted using a self-reported questionnaire. Data were collected from July to September 2020. The study participants were 212 individuals with various major mental disorders. Results: Depression was found to be positively correlated with alcohol drinking, psychiatric symptoms, and suicidal ideation. Alcohol use was positively correlated with psychiatric symptoms and suicidal ideation, and psychiatric symptoms were positively correlated with suicidal ideation. Factors influencing suicidal ideation included suicidal attempts, psychiatric symptoms, depression, and awareness of the mental health crisis hotline. Multiple regression analysis showed these variables explained 61% of suicidal ideation. Conclusion The study shows that to prevent suicide among the mentally ill, focus should be placed on reducing depression, alcohol drinking, and psychiatric symptoms and improving awareness of the mental health crisis hotline.

OBJECTIVES: Mushrooms, known for their nutritious and functional components, are considered healthy and medicinal. This study investigated the prospective association between dietary mushroom consumption and the incidence of type 2 diabetes among Korean adults aged ≥40 years. METHODS: In total, 16,666 participants who were not taking anti-diabetic medication or insulin and had normal fasting blood glucose (FBG; <126 mg/dL) were included. We used the cumulative average dietary consumption of mushrooms as an exposure metric, calculated from food frequency questionnaires at every follow-up, along with covariates collected during a baseline survey. To estimate incidence rate ratios (IRRs) for type 2 diabetes, a modified Poisson regression model with a robust error estimator was applied. RESULTS: In multivariable models, dietary mushroom consumption was inversely associated with type 2 diabetes incidence in both genders (men: IRR, 0.65; 95% confidence interval [CI], 0.47 to 0.90; plinearity=0.043 in the highest quartile (Q4) vs. the lowest quartile (Q1); women: IRR, 0.70; 95% CI, 0.54 to 0.93; plinearity=0.114 in Q4 vs. Q1). The inverse association remained after adjustment for dietary factors instead of dietary quality index, the baseline FBG, and the exclusion of incidence within the first year. Additionally, no significant interaction was found regarding the risk of type 2 diabetes between dietary mushroom consumption and participants’ gender or other factors. CONCLUSIONS Dietary mushroom consumption was inversely linked with the risk of type 2 diabetes incidence in both genders, indicating the beneficial role of mushrooms in preventing the disease.

OBJECTIVE: Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by increased production of cytokines, proliferation of fibroblast-like synoviocytes (FLS) and joint destruction. It is well known that the involved joints in RA are hypoxic. Hypoxia may play a role in the pathogenesis of RA. We thought that hypoxia might alter the production of cytokines by FLS and these changes could affect the biologic behaviors of FLS. Based on that, we investigated whether hypoxia affects the production of cytokines in FLS and the effect of these changes on matrix metalloproteinases (MMPs) expression. METHODS: Fibroblast-like synoviocytes from human rheumatoid synovial tissue obtained duringjoint replacement surgery were cultured in vitro. Hypoxic culture was performed by incubating cells in BBL? Gaspak pouchTM anaerobic system. After incubation under hypoxic condition for 24 hr, the concentrations of various cytokines in culture supernatants were determined by ELISA. To determine the effect of highly expressed cytokines on MMP expression, we performed ELISA of MMP-1, MMP-2 and MMP-3 in cultured FLS, after stimulation with respective cytokines. RESULTS: In hypoxic state, IL-6, IL-8 and vascular endothelial growth factor (VEGF) concentrations were significantly increased compared to those in normoxic condition. However, there were little differences in IL-1, IL-2, IL-4, TNF-alpha and TGF-beta. Stimulation of FLS with IL-6 and IL-8 showed the increased concentrations of MMP-1, MMP-2 and MMP-3. CONCLUSION: Hypoxic environment of rheumatoid synovium might affect FLS to produce proinflammatory and proangiogenic cytokine such as IL-6 and IL-8. These cytokines again could stimulate MMPs production in FLS leading to joint destruction.

The association between nephrotic syndrome and intravascular coagulation has been known for more than a century, but it was not until 1948 that a thrombotic diathesis in nephrotic patients was proposed. The prevalence of thrmbo-embolic complications is much higher in adult patients. Deep vein thrombosis of the leg is the most common complications in nephrotic adult and was responsible for one-third of the thrombo-embolic complications of nephrotic children. Arterial thrombosis occurs less frequently and is seen primarily in childern. We present a case of acute anterior myocardial infarction in a young man with nephrotic syndrome, secondary to minimal change glomerulonephritis, in which thrombosis of the proximal left anterior descanding artery was the actual cause of acute myocardial infarction.

In situ hybridization using radioactively labeled(S) and nonradioactively labeled probes was performed to detect HPV DNA and to compare the sensitivity of two probes in 17 patients with genital warts showing atypical manifestations. HPV 6/ll was found in 100%(3/3) of the flat type, 50%(2/4) of the pigmented type and 66.7%(2/3) of the flat and pigmented type (except bowenoid papulosis) and 66.7%(2/3) of the large extensive type. However HPV 16/18 was not found at all. In bowenaid papulosis, HPV 16/18 was detected in 25% (1/4) of the cases but HPV 6/11 was negative in all cases. There was no significant difference between the sensitivity of radioactiue and nonradioactive probes. HPV 6/11 was positive in the giant condyloma acuminata complicated with squamous cell carcinoma.

BACKGROUND AND OBJECTIVES: There are no reported studies of olfactory function of Korean children, and the existing tests of olfactory function for Korean adults may not be suitable for very young children. This study assessed the applicability of the Butanol Threshold Test (BTT) and Cross-Cultural Smell Identification Test (CC-SIT) to children. SUBJECTS AND METHOD: A total of 79 children were included in the study: they were between 6-12 years of age, and had visited University Hospital Health Care Center between January 2012 and December 2013. All children were administered the BTT and CC-SIT. RESULTS: Using BTT, 69.62% of the sample was classified as moderate hyposmia. On the other hand, when CC-SIT was used, 45.57% of the sample was classified as moderate and 43.04% as mild hyposmia. CC-SIT and BTT scores were not correlated. Although gender and age were not taken into account in the test results, the CC-SIT could measure age-specific olfactory development. CONCLUSION: Our study provides fundamental data on the clinical use of the CC-SIT and BTT in healthy Korean children.

OBJECTIVES: Limited and inconsistent prospective evidence exists regarding the relationship of dietary total antioxidant capacity (dTAC) and antioxidant intake with metabolic syndrome (MetS) risk. We evaluated the associations of the cumulative averages of dTAC and antioxidant intake (in 5 classes: retinol, vitamin C, vitamin E, carotenoids, and flavonoids, as well as 7 flavonoid subclasses) with the risk of MetS. METHODS: This study included 11,379 participants without MetS, drawn from the Korean Genome and Epidemiology Study_CArdioVascular disease Association Study (KoGES_CAVAS). The cumulative average consumption was calculated using repeated food frequency questionnaires. Incidence rate ratios were estimated using a modified Poisson regression model with a robust error estimator. RESULTS: The median follow-up period was 5.16 years, and 2,416 cases of MetS were recorded over 58,750 person-years. In men, significant inverse associations were observed in all 5 antioxidant classes, except for the highest quartile of dTAC. In women, dTAC and total flavonoids were not significantly associated with MetS; however, significant L-shaped associations were found for the remaining 4 antioxidant classes. Of the 7 flavonoid subclasses, only flavones in the highest quartile for men and flavan-3-ols in women lacked significant associations with MetS. The inverse associations were not sex-specific, but they were particularly pronounced among participants with a body mass index (BMI) of 23 kg/m2 or higher. CONCLUSIONS The findings suggest that most antioxidant classes and flavonoid subclasses, unlike dTAC, exhibit a clear beneficial association with MetS in an L-shaped pattern in both men and women, particularly those with a high BMI.
