Purpose: The homelessness problem in Korea has developed into a social structural and economic problem, as the number of homeless people continues to increase. The purpose of this study is to verify the effect of self-reliance on the homeless by applying group logotherapy. Methods: This study used a Nonequivalent control group pretest‐ posttest design. 74 participants were used for analysis. Intervention group, 37 homeless people participated in the logotherapy for 5 weeks, and the effect was measured through pre, post, and 4 weeks follow-up tests. The research results were analyzed using a Repeated measure ANCOVA. Results: As a result, the difference in intervention variables according to the interaction between time * groups was significant. The meaning in life and self efficacy significantly increased in the intervention group than in the control group, and depression significantly decreased. Conclusion As a result, it can be seen that the logotherapy program is effective in increasing the meaning in life and self efficacy of homeless people's lives and reducing depression. Based on the results of this study, it is expected that the group logotherapy program will be actively used as a program for self‐reliance of the homeless person.

Purpose: : This study aimed to assess the effectiveness of an advanced practice nurse (APN)-driven ventilator weaning protocol for patients undergoing cardiac surgeries. Methods: : A retrospective analysis was conducted on 226 patients admitted to the intensive care unit (ICU) of a tertiary hospital between January and June 2020, following a cardiac surgery. Patients were divided into an APN protocol-applied group (experimental group, n=152) and a control group managed based on doctors' judgment (n=74). Ventilator weaning criteria and clinical outcomes, including duration of ventilation, length of ICU stay, and rate of reintubation, were compared between the two groups. Results: : Patients in the control group were older and had a higher incidence of massive bleeding from chest tube drainage (＞100 cc/hr) at baseline. The average duration of ventilation was significantly shorter in the experimental group compared to the control group (7.44 vs. 21.61 hours, p ＜.001). Furthermore, the mean length of ICU stay was shorter in the experimental group compared to the control group (47.96 vs. 77.97 hours, p ＜.001). There was no difference in the rate of reintubation between the two groups. Conclusion : These findings suggest that an APN-driven ventilator weaning protocol can improve clinical outcomes without significant complications. These results support the adoption of APN-driven mechanical ventilator weaning protocols in clinical practice.

Purpose: To determine the efficacy of immediate pars plana vitrectomy as the primary treatment for acute endophthalmitis in patients with a visual acuity (VA) of hand motion (HM) or better. Methods: A total of 149 patients who were referred to a single center for acute endophthalmitis after cataract surgery over the 13-year study period were retrospectively analyzed. Only patients presenting with a VA of at least HM were included. Patients were initially treated with either primary vitrectomy or intravitreal antibiotic injection alone, and their visual outcomes and reintervention rates after initial treatment were compared. Results: There was no significant difference in the proportion of good (final VA ≥20 / 40) and poor (VA ≤ counting finger) visual outcomes between the groups. However, subgroup analysis of patients with a VA of HM (92 eyes) showed that the incidence of reintervention (14 of 72 eyes [19.4%] vs. 9 of 20 eyes [45.0%]) and poor visual outcomes (10 of 72 eyes [13.9%] vs. 8 of 20 eyes [40.0%]) were lower after prompt vitrectomy than after intravitreal antibiotic injection alone (p = 0.019 and p = 0.022, respectively). For those with a VA of at least counting finger, no significant difference was observed between the groups. Conclusions For patients with endophthalmitis presenting with a VA of HM, performing a prompt vitrectomy reduced the incidence of reintervention and poor visual outcomes than the administration of intravitreal antibiotics alone. Our results suggest that primary vitrectomy for patients with endophthalmitis presenting with a VA of HM could be more beneficial than intravitreal antibiotic injection alone.

A 10-year-old spayed female Maltese presented with purpura and hematemesis. Initial laboratory evaluation revealed immune-mediated thrombocytopenia, but evidence of hemolytic anemia was not identified. Three milligrams of human intravenous immunoglobulin (hIVIG) was administered for 3 hours following prednisolone and mycophenolate mofetil. A pale mucous membrane was identified, and the packed cell volume decreased by 3%. Blood film examination revealed significant spherocytosis with auto-agglutination. Blood transfusions and immunosuppression were continued for 4 days, and hIVIG was discontinued. This report describes a case of increased immune-mediated hemolysis after hIVIG administration, possibly due to new-onset immune-mediated hemolytic anemia or enhanced immunogenicity.

BACKGROUND: Enquiry into smoking status and recommendations for smoking cessation is an essential preventive service. However, there are few studies comparing self-reported (SR) and cotinine-verified (CV) smoking statuses, using medical check-up data. The rates of discrepancy and under-reporting are unknown. METHODS: We performed a cross-sectional study using health examination data from Healthcare System Gangnam Center, Seoul National University Hospital in 2013. We analyzed SR and CV smoking statuses and discrepancies between the two in relation to sociodemographic variables. We also attempted to ascertain the factors associated with a discrepant smoking status among current smokers. RESULTS: In the sample of 3,477 men, CV smoking rate was 11.1% higher than the SR rate. About 1 in 3 participants either omitted the smoking questionnaire or gave a false reply. The ratio of CV to SR smoking rates was 1.49 (95% confidence interval [CI], 1.38-1.61). After adjusting for confounding factors, older adults (≥60 years) showed an increased adjusted odds ratio (aOR) for discrepancy between SR and CV when compared to those in their twenties and thirties (aOR, 5.43; 95% CI, 2.69-10.96). Educational levels of high school graduation or lower (aOR, 2.33; 95% CI, 1.36-4.01), repeated health check-ups (aOR, 1.45; 95% CI, 1.03-2.06), and low cotinine levels of <500 ng/mL (aOR, 2.03; 95% CI, 1.33-3.09), were also associated with discordance between SR and CV smoking status. CONCLUSION: Omissions and false responses impede the accurate assessment of smoking status in health check-up participants. In order to improve accuracy, it is suggested that researcher pay attention to participants with greater discrepancy between SR and CV smoking status, and formulate interventions to improve response rates.

BACKGROUND: Based on outstanding progresses in animal experiments, vaccines for some human tumors have been developed. However, clinical effects of these vaccines have been far below than expected. This discrepancy might come from differences between animal models and human patients with respect to immunocompetency. The immune status of mice after tumor inoculation has not been well studied, which make us cautious in interpreting and applying the results from mice to human. We evaluated cell-mediated immune responses in mice after tumor cell inoculation. METHODS: Mice were inoculated with TA3Ha, CT26, or 4T1. Delayed-type hypersensitivity (DTH) responses were induced 2-4 weeks after inoculation using 2,4-dinitro-1-fluorobenzene as an antigen. The relationships between the severity of DTH responses and the duration of tumor inoculation or the size of tumor mass were analyzed. RESULTS: In TA3Ha groups, DTH response was elevated 2 weeks after inoculation, but depressed after 4 weeks, compared to the control group. When analyzed based on the sizes of tumor masses elicited, DTH responses were inversely related to the mass size, especially in those greater than 10 mm in diameter. In CT26 groups, while the duration after inoculation did not affect the severity of DTH responses, those with large mass showed depressed responses regardless the duration of inoculation. 4T1 cells grew so slowly that the size of tumor mass was small even 4 weeks after inoculation, and this group showed much higher DTH responses compared to that of tumor-free group. CONCLUSION: At least in an experimental setting where tumor model was induced by inoculating tumor cell lines into immunologically competent mice, the host immune response was elevated in early stage, and then depressed in late stage when the mass grew over a critical size.

PURPOSE: Non-small cell lung carcinoma (NSCLC) comprises 75-85% of all lung cancers, and approximately 25% of all NSCLC patients develop brain metastasis. There are no reliable markers for predicting in which patients this metastasis will occur. DCUN1D1, also known as squamous cell carcinoma-related oncogene, is associated with tumor progression and poor outcomes in NSCLC. The objective of this study was to investigate the role of DCUN1D1 expression in cases of brain metastasis due to NSCLC. MATERIALS AND METHODS: Primary tumor samples from a total of 71 cases of NSCLC, either with (n=40) or without (n=31) brain metastasis, were evaluated for DCUN1D1 expression by immunohistochemistry analysis. RESULTS: DCUN1D1 expression was detected in 16 patients (23%) and tended to correlate with T classification (15% of T1-2 tumors vs. 30% of T3-4 tumors, p=0.083). DCUN1D1 expression was significantly associated with tumor stage. It was observed in none of the patients with stage I disease, 10% of those with stage II disease, and 29% with stage III disease (p=0.009). In addition, 14 of 16 DCUN1D1-positive patients resulted in brain metastasis (p=0.01). The odds ratio of brain metastasis for patients with DCUN1D1 expression was 3.112 (p=0.009). CONCLUSION: DCUN1D1 expression may play a role in tumor progression and development of brain metastasis in patients with NSCLC. Evaluation of DCUN1D1 expression may provide assistance in identifying those patients who are at higher risk for brain metastasis.

We report two cases of giant cell tumor arising from the rib and their F-18 FDG PET/CT findings. The two patients complained of chest wall pain, and large lobulated soft tissue masses with intense FDG uptake were seen on F-18 FDG PET/CT. A malignant tumor such as osteosarcoma or chondrosarcoma was suspected due to the large size of the mass, bony destruction, and intense FDG uptake. En bloc resection was performed and final pathologic results revealed giant cell tumor of the rib. Giant cell tumor of the rib is very rare, and larger lesions with high FDG uptake can be misdiagnosed as an intrathoracic malignancy arising from the rib, pleura, or chest wall.

BACKGROUND/AIMS: This study was aimed to investigate the current clinical status of endoscopic submucosal dissection (ESD) for early gastric cancer (EGC) in Korea based on a National Health Insurance (NHI) database between 2011 and 2014. METHODS: The claims data of ESD for EGC in Korean NHI were reviewed using material codes of Health Insurance Review and Assessment Service between November 2011 and December 2014. The current clinical status was analyzed in terms of treatment pattern, in-hospital length of stay (LOS), total medical costs, and en bloc resection rate according to the hospital type. RESULTS: A total of 23,828 cases of ESD for EGC were evaluated. ESD was performed in 67.4% of cases in tertiary care hospitals, 31.8% in general hospitals, and 0.8% in hospitals, respectively. The median LOS was 5 days, and total median medical costs was approximately 1,300 US dollars. En bloc resection rate was 99%; 8.5% of cases underwent additional treatment within 90 days ESD, and 5.5% in 91 to 365 days after ESD. The clinical status was not significantly different according to the year and hospital type. CONCLUSIONS A majority of ESD for EGC were performed in tertiary care hospitals in Korea. The clinical status showed excellent clinical outcomes and did not differ by the year and between the types of hospitals in Korea.

Purpose: In the Tokyo Guidelines 2018 (TG18), emergency laparoscopic cholecystectomy is recognized as a crucial early treatment option for acute cholecystitis. However, early laparoscopic intervention in patients with moderate-to-severe acute cholecystitis or those with severe comorbidities may increase the risk of complications. Therefore, in the present study, we investigated the association between early laparoscopic cholecystectomy and percutaneous transhepatic gallbladder drainage (PTGBD) in moderate-to-severe acute cholecystitis patients. Methods: We retrospectively analyzed 835 TG18 grade II or III acute cholecystitis patients who underwent laparoscopic cholecystectomy at 4 tertiary medical centers in the Republic of Korea. Patients were classified into 2 groups according to whether PTGBD was performed before surgery, and their short-term postoperative outcomes were analyzed retrospectively. Results: The patients were divided into 2 groups, and 1:1 propensity score matching was conducted to establish the PTGBD group (n = 201) and the early laparoscopic cholecystectomy group (n = 201). The PTGBD group experienced significantly higher rates of preoperative systemic inflammatory response syndrome (24.9% vs. 6.5%, P < 0.001), pneumonia (7.5% vs.3.0%, P = 0.045), and cardiac disease (67.2% vs. 57.7%, P = 0.041) than the early operation group. However, there was no difference in biliary complication (hazard ratio, 1.103; 95% confidence interval, 0.519–2.343; P = 0.799) between the PTGBD group and early laparoscopic cholecystectomy group. Conclusion In most cases of moderate-to-severe cholecystitis, early laparoscopic cholecystectomy was relatively feasible.However, PTGBD should be considered if patients have the risk factor of underlying disease when experiencing general anesthesia.
