PURPOSE: The purpose of this study is to identify the correlation that exists between quality of life and self-efficacy of schizophrenic patients, focusing on the influence of related factors on these varables. METHOD: The subjects of this study were 151 schizophrenic patients. The data were collected using questionnaires. The instruments used for this study were the general self-efficacy scale developed by Sherer & Maddex (1982), the specific self-efficacy scale modified and complemented by these co-researchers on the basis of the past studies and modified SIP by Voruganti (1996). The period of data collection was from July. 2000 to Jan. 2001. Data analysis was done by SPSS, t-test, ANOVA and the Pearson Correlation Coefficient. RESULT: 1. The level of self-efficacy showed a mean score of 60.0 and the level of quality of life, a mean score of 47.0. 2. The general characteristics affecting the self-efficacy of schizophrenic patients were staying with family (p=0.05) and employment (p=0.00). 3. The general characteristics affecting the quality of life of schizophrenic patients were staying with family (p=0.04), employment (p=0.05) and duration of illness (0.03). 4. A positive correlation was identified between self-efficacy and quality of life (r=-0.469, p=0.000). CONCLUSION: The study suggests that nursing intervention strategy should be worked out to develop a psychiatric rehabilitation program that can promote self-efficacy and thus enhance the quality of life of schizophrenic patients.

Background: Non-alcoholic fatty liver disease (NAFLD) recently became a leading liver disease that threatens health worldwide. Low muscle strength, obesity, insulin resistance, and metabolic syndrome are recognized key factors for NAFLD. However, the impact of low muscle strength itself in different metabolic conditions has not been widely studied. Methods: A cross-sectional analysis was performed of a sample of 5,427 participants from the 2019 Korea National Health and Nutrition Examination Survey. Relative handgrip strength (rHGS, defined as handgrip strength/body mass index) was used to assess muscle strength. The cut-off values for a low rHGS were 1.405 for men and 0.850 for women. NAFLD was diagnosed if the Hepatic Steatosis Index was >36. Participants were stratified according to insulin resistance, metabolic syndrome, and central obesity for the subgroup analyses. Results: Complex sample multivariate logistic regression analysis revealed a significant association between low muscle strength and NAFLD after the adjustment for other confounders (odds ratio [OR], 1.92; P<0.001). In the insulin resistance, metabolic syndrome, and central obesity subgroups, a significant association between low muscle strength and NAFLD remained (OR, 1.66–4.19 depending on subgroup; all P<0.05), whereas it did not in the no central obesity group. Conclusion This study demonstrated that low muscle strength is correlated with a risk of NAFLD. This relationship was independent of insulin resistance and metabolic syndrome but was dependent on the presence of central obesity.

Actinomycosis still poses a problem for correct clinical and radiologic diagnosis. We retrospectively analyzed CT findings in 7 patients with pathologically proven abdominal actinomycosis. Involved areas were the pelvis (n=3), greater omentum (n=2), liver (n=1), and kidney (n=1). CT confirmed the infiltrative nature of the disease with a tendency to invade across tissue plane and boundary. Five of seven cases were predominantly solid mass (pseudotumor) with focal low-attenuation areas while two were predominantly cystic mass with thickened wall. Contrast-enhanced CT showed dense, inhomogeneous contrast enhancement in the wall and/ or solid components of the masses in five. Minimal lymphadenopathy was noted in one case. CT is useful in demonstrating the extent and characteristics of this disease. Despite nonspecific findings, actinomycosis should be included in the differential consideration when CT shows an infiltrative mass with unusual aggressiveness and dense inhomogeneous contrast enhancement in patients with fever, leukocytosis, or long-term use of intrauterine contraceptive devices.

Background and Objectives: This study investigated whether an artificial intelligence computer-assisted diagnosis (AI-CAD) software recently developed in our institution named the Severance Artificial intelligence program (SERA) could show similar diagnostic performance for thyroid cancers using ultrasonographic (US) images from a mobile phone (SERA_M) compared to using images directly downloaded from the pictures archive and communication system (PACS) (SERA_P). Materials and Methods: From October 2019 to December 2019, 259 thyroid nodules from 259 patients were included. SERA was run on original and mobile images to evaluate SERA_P and SERA_M. Nodules were categorized according to the American College of Radiology Thyroid Imaging Reporting and Data System (ACR TI-RADS). To compare diagnostic performance, a logistic regression analysis was conducted using the Generalized Estimating Equation. The area under the curve (AUC) was calculated using the receiver operating characteristic (ROC) curve, and compared using the Delong Method. Results: There were 40 cancers (15.4%) and 219 benign lesions (84.6%). The AUC and sensitivity of SERA_M (0.82 and 85%, respectively) were not statistically different from SERA_P (0.8 and 75%, respectively) (p=0.526 and p=0.091, respectively). The AUC of radiologists (0.856) was not significantly different compared to SERA_P and SERA_M (p=0.163 and p=0.414, respectively). The sensitivity of radiologists (77.5%) was not statistically different compared to SERA_P and SERA_M (p=0.739 and p=0.361, respectively). Conclusion AI-CAD software using pictures taken by a mobile phone showed comparable diagnostic performance with the same software using images directly from PACS.

BACKGROUND: Despite advances in the treatment of primary cancer, metastatic pathologic fractures still affect the survival of cancer patients. The goals of surgery, such as those with terminal cancer, are to maintain a maximum level of independence and improve the quality of life. A patient may be a poor surgical candidate because of a short life expectancy or illness that is too severe to benefit from surgical fixation. Moreover, this surgery is an operation accompanied with significant morbidity and mortality. This retrospective study investigated the characteristics of these patients and assessed the influence of anesthetic risk factors on the outcome. METHODS: The records of 45 patients with pathologic fractures who underwent surgical stabilization for metastatic factors from 1 January 1995 to 31 December 2013 at our hospital were reviewed. Demographic data, various severity scores, anesthetic factors, and survival were reviewed. RESULTS: The most common sites of primary tumors were lung, liver and stomach. The predominant sites of pathologic fractures were the femur (71.1%); six lesions were in the humerus and four in the spine. Univariate and multivariate analyses identified several prognostic factors with a significantly worse influence on survival, including lung tumor and Acute Physiology and Chronic Health Evaluation (APACHE) II score. CONCLUSIONS: Although the number of patients was too small to result in a satisfactory appraisal, the most important step is to select candidates to gain the benefits of palliative surgery. We suggest the possibility of APACHE II scoring and the recognition of lung cancer in making the clinical decision of performing the palliative osteosyntheses for patients with pathologic fractures.

The present study was undertaken to explore whether retinoids, which are known to have immunomodulatory actions, could attenuate tumor necrosis factor-alpha (TNF)-stimulated inducible nitric oxide synthase (iNOS) expression in 3T3-L1 adipocytes. Adipocytes incubated with TNF induced dose- and time-dependent accumulation of nitrite in the culture medium through the iNOS induction as confirmed by Western blotting. Treatment of cells with TNF in the presence of all-trans-retinoic acid (RA) significantly decreased their ability to produce nitrite and iNOS induction. Both 13-cis- and all- trans-RA-induced suppression was dose-dependent, and all-trans-RA was somewhat potent than 13-cis-RA. The inhibitory effect of RA on TNF-induced iNOS induction was reversible, completely recovered after 2 days, and was exerted through the inhibition of NF-kappaB activation. TNF also suppressed the lipoprotein lipase (LPL) activity of 3T3-L1 adipocytes. RA could not reverse the TNF- induced LPL suppression at RA levels causing near complete inhibition of the TNF-induced NO production. These results indicate that RAs attenuate iNOS expression reversibly in TNF-stimulated 3T3-L1 adipocytes, and that the TNF- induced LPL suppression is not the result of NO overproduction.

BACKGROUND: Analysis of mutations in the epidermal growth factor receptor gene (EGFR) is important for predicting response to EGFR tyrosine kinase inhibitors. The overall rate of EGFR mutations in Korean patients is variable. To obtain comprehensive data on the status of EGFR mutations in Korean patients with lung cancer, the Cardiopulmonary Pathology Study Group of the Korean Society of Pathologists initiated a nationwide survey. METHODS: We obtained 1,753 reports on EGFR mutations in patients with lung cancer from 15 hospitals between January and December 2009. We compared EGFR mutations with patient age, sex, history of smoking, histologic diagnosis, specimen type, procurement site, tumor cell dissection, and laboratory status. RESULTS: The overall EGFR mutation rate was 34.3% in patients with non-small cell lung cancer (NSCLC) and 43.3% in patients with adenocarcinoma. EGFR mutation rate was significantly higher in women, never smokers, patients with adenocarcinoma, and patients who had undergone excisional biopsy. EGFR mutation rates did not differ with respect to patient age or procurement site among patients with NSCLC. CONCLUSIONS: EGFR mutation rates and statuses were similar to those in published data from other East Asian countries.
