Tendon and ligament (T/L) have been known to be obviously different from each other in tissue level. However, due to the overlapping gene markers, distinction in cellular level has not been clearly verified yet. Recently, the use of nuclear magnetic resonance (NMR) spectroscopy has shown the potential to detect biological markers in cellular level. Therefore, in this study we applied a non-invasive technique based on NMR spectroscopy to establish biomarkers to distinguish between T/L fibroblasts. In addition the cellular morphologies and gene expression patterns were also investigated for comparison through optical microscopy and real-time polymerase chain reaction (PCR). No difference was observed from morphology and real-time PCR results, either as expected. However, we found clear differences in their metabolomic spectra using ¹H NMR spectroscopy. The calculated integral values of fatty acids (with chemical shifts at ~0.9, 1.26, 1.59, 2.05, 2.25, and 2.81 ppm), lactate (~1.33 ppm), and leucine (~2.72 ppm) were significantly different between the two types of fibroblasts. To be specific tendon group exhibited higher level of the metabolite than ligament group. In conclusion, in-cell metabolomic evaluation by NMR technique used in this study is believed to provide a promising tool in distinguishing cell types, especially T/L cells, which cannot be classified by conventional biological assays.

OBJECTIVE: This study was conducted to assess the interaction between alcohol cues and social pressure in the induction of alcohol craving. METHODS: Fourteen male patients with alcohol dependence and 14 age-matched social drinkers completed a virtual reality coping skill training program composed of four blocks according to the presence of alcohol cues (x2) and social pressure (x2). Before and after each block, the craving levels were measured using a visual analogue scale. RESULTS: Patients with alcohol dependence reported extremely high levels of craving immediately upon exposure to a virtual environment with alcohol cues, regardless of social pressure. In contrast, the craving levels of social drinkers were influenced by social pressure from virtual avatars. CONCLUSION: Our findings imply that an alcohol cue-laden environment should interfere with the ability to use coping skills against social pressure in real-life situations.

OBJECTIVE: This study was performed to compare the changes in the blood concentrations of tacrolimus when either itraconazole or voriconazole is together with tacrolimus to prevent or treat invasive aspergillus pneumonia (IAP) in patients with lung transplants. Therefore we can compare the degree of drug-drug interactions between tacrolimus and itraconazole against tacrolimus and voriconazole. METHODS: Patients who were admitted and had lung transplants in a territory referral hospital from September 2012 to May 2015 were analyzed retrospectively. The effects of itraconazole and voriconazole on the plasma concentrations of tacrolimus were analyzed. RESULTS: Mean tacrolimus concentrations was 10.49±2.35 ng/mL vs. 10.95±2.98 ng/mL (p=0.722), and mean concentration of tacrolimus over the dose of tacrolimus per day was 8.510±5.890 (ng/mL)/(mg/d) vs. 15.45±28.47 (ng/mL)/(mg/d) (p=0.947) in itraconazole vs. voriconazole group each. The ratio of the number of the results out of target tacrolimus concentrations to the total number of tacrolimus concentration results was 18.0±13.3% vs. 24.4±18.5% (p=0.185). CONCLUSION: There were no significant differences between itraconzaole and voriconazole to have influences on mean concentrations of tacrolimus over tacrolimus dose per weight per day. However voriconazole tended to raise tacrolimus plasma concentrations more than itraconazole. Safer and more effective drug management to prevent and treat fungal infections should be done by therapeutic drug monitoring not only of tacrolimus but of itraconazole and voriconazole in lung transplant patients.

Purpose:
This study aimed to examine the relationships between participative decision-making, psychological empowerment, and organizational citizenship behavior of nurses working in hospitals; moreover, we verified the moderated mediating effect of power distance orientation in these relationships.
Methods:
A total of 201 nurses working at a university hospital in South Korea responded to the survey. Self-report surveys were used to gather data from July 15-August 15, 2021. SPSS 22.0, AMOS 22.0, and SPSS PROCESS macro were used for data analysis.
Results:
Psychological empowerment significantly mediated the relationship between participative decision making and organizational citizenship behavior. Moreover, the moderating effect of power distance orientation on the relationship between participative decision making and psychological empowerment was also significant when the power distance orientation was at a low and average levels. However, the moderated mediating effect of power distance orientation on the relationship between participative decision making, psychological empowerment, and organizational citizenship behavior was insignificant.
Conclusion
Involving nurses with lower power distance orientation in decision making is crucial to elicit positive work performance and different strategies are necessary for those with higher power distance orientation. Finally, further studies are needed to understand the power distance orientation and positive work outcomes of nurses.

Wilson's disease is a rare autosomal recessive metabolic disease. The ATB7B gene mutation results in a defect of biliary copper excretion and subsequent accumulation of copper in the liver, brain, and sclera. The usual clinical signs of Wilson's disease include hepatitis, liver cirrhosis, movement disorder, or a Kayser-Fleisher ring in the sclera, but patients occasionally present with hepatic failure or hemolytic anemia. Under such metabolic conditions, free copper induce chronic hemolysis with oxidative damage via free radical production, and chronic hemolysis, in turn, can cause secondary pigment bililary stone formation. Herein we report a case of Wilson's disease associated with cholelithiasis in a young female.

OBJECTIVE: Anxious depression has a distinct neurobiology, clinical course and treatment response from non-anxious depression. Role of inflammation in anxious depression has not been examined. As an exploratory study to characterize the role of inflammation on a development of anxious depression, we aimed to determine the relationship between white blood cell (WBC) subset counts and anxiety in individuals with major depressive disorder (MDD). METHODS: A total of 709 patients who were newly diagnosed with MDD were recruited. Anxiety levels of participants were evaluated using the Anxiety/ Somatization subitem of the Hamilton Depression Rating Scale. The association between WBC subset fraction and anxiety was evaluated. RESULTS: Basophil and eosinophil sub-fractions showed significant negative correlations with HAM-D anxiety/somatization factor scores (basophils: r=-0.092, p=0.014 and eosinophils: r=-0.075, p=0.046). When an anxiety score (a sum of somatic and psychic anxiety) was entered as a dependent variable, only basophils showed significant negative association with the anxiety scores after adjusting for all other WBC subset counts and demographic factors (t=-2.57, p=0.010). CONCLUSION: This study showed that anxious depression had a decreased basophil subfraction, which might be associated with involvement of inflammation in development of anxious depression.

OBJECTIVES: Gestational diabetes mellitus (GDM) affects 2%-4% of the all pregnant women, and it is a major risk factor for development of type 2 DM. We performed this cross-sectional study to determine whether there were defects in insulin secretory capacity or insulin sensitivity in women with previous GDM. METHODS: On 6-8 weeks after delivery, 75 g oral glucose tolerance test was performed in 36 women with previous GDM and 19 non-pregnant control women matched with age and weight. Intravenous glucose tolerance test was performed on 10-14 weeks after delivery. Insulin secretory capacity measured as the acute insulin response to glucose (AIRg) and insulin sensitivity as minimal model derived sensitivity index (S(I)) were obtained. AIRg x S(I) (beta-cell disposition index) was used as an index of beta-cell function. RESULTS: Women with previous GDM were classified into normal glucose tolerance (postpartum-NGT, n=19) and impaired glucose tolerance (postpartum-IGT, n=17). Postpartum fasting glucose levels were significantly higher in postpartum-IGT compared to postpartum-NGT and control (P<0.05). AIRg x S(I) was significantly lower in postpartum-IGT compared to control (P<0.05). S(I) was lower in postpartum-NGT and postpartum-IGT compared to control, but the difference did not have the statistical significance. Frequency of parental history of type 2 diabetes was significantly greater in postpartum-IGT compared to postpartum-NGT (P<0.05). CONCLUSION: Women with previous GDM showed impaired insulin secretion although their glucose tolerance states were restored to normal. It suggests impaired early insulin secretion may be a major pathophysiologic factor for development of type 2 DM, and this defect may be genetically determined.

BACKGROUND: This study aimed to analyze correlations between depression, cognitive function, oral health state, ability to perform activities of daily living, oral dryness symptoms, and oral health-related quality of life, and determine factors influencing the latter.METHODS: This was a cross-sectional study based on questionnaires completed by 260 participants with suspected dementia, residing in South Korea. Psychiatrists, psychiatric nurses, and dental hygienists visited clinics in the participating regions for examination and questionnaire administration. General characteristics, the geriatric depression scale, ability to perform activities of daily living, cognitive function, oral health state, and oral health-related quality of life were analyzed. Independent t-tests, one-way analysis of variance (ANOVA), correlation analysis and multiple regression analysis were conducted, identifying factors affecting oral health-related quality of life. Data analysis was performed using SPSS ver. 20.0 (IBM Corp., USA), and the significance was set at p<0.05.RESULTS: Approximately 65.0% of participants were female, 63.5% were in their 70s, and 90.0% had health insurance. About 21.5%, 42.0%, and 36.5% were normal, slightly impaired, and had dementia, respectively. High cognitive impairment was associated with poor oral health. Sex, education levels, marital status, and living arrangements influenced oral health-related quality of life. According to the regression analysis, geriatric depression and oral dryness affected the Geriatric Oral Health Assessment Index scores.CONCLUSION: In conclusion, oral dryness and depression levels among elders influenced oral health-related quality of life. The results showed that to enhance elders' oral health-related quality of life, it is essential to not only improve their oral health state, but also relieve oral health problems, especially oral dryness, and take into consideration their psychological aspects.

BACKGROUND/OBJECTIVES:
Hydrolyzed formula is often fed to infants with gastrointestinal or immune issues, such as malabsorption or cow's milk allergy, because enzymatic treatment has rendered it more digestible and less allergenic than standard cow's milk formula (SF). Partially hydrolyzed formula (PHF) should be considered for those infants who are intolerant to extensively hydrolyzed formula. However, there are concerns about the nutritional insufficiencies of PHF. We aimed to evaluate the effects of PHF on the growth and health indicators in infants who were at high-risk of allergic disease and potential candidates for consuming PHF.
SUBJECTS/METHODS:
A total of 83 infants aged 0–2 mon with a family history of allergies were assigned to consume either PHF or SF until 24 weeks of age. Anthropometric measures were obtained at baseline, 12 weeks, and 24 weeks; blood samples were drawn and evaluated at the end of the study.
RESULTS:
No significant differences were observed in weight, height, and weight-for-height at any time point in each sex between the PHF and SF groups. At 24 weeks of age, the weightfor-age and height-for-age z-scores of the SF group were higher than those of the PHF group, but there was no significant difference in the weight-for-height z-score. There were no significant differences in levels of white blood cells, hemoglobin, ferritin, protein, albumin, aspartate aminotransferase, alanine aminotransferase, eosinophil cationic protein, and immunoglobulin E.
CONCLUSIONS
In this study, there were no differences in growth and blood panels between the infants consuming PHF or SF. Therefore, infants who are unable to tolerate SF can be fed PHF without nutritional concerns about growth.
