1.Family’s Perception of Proxy Decision Making to Authorize Do Not Resuscitate Order of Elderly Patients in Long Term Care Facility: A Q-Methodological Study
Journal of Korean Academy of Nursing 2021;51(1):15-26
Purpose:
This study aimed to distinguish and describe the types of perceptions of do not resuscitate (DNR) proxy decisions among families of elderly patients in a long-term care facility.
Methods:
This exploratory study applied Q-methodology, which focuses on individual subjectivity. Thirty-four Q-statements were selected from 130 Q-populations formed based on the results of in-depth interviews and literature reviews. The P-samples were 34 families of elderly patients in a long-term care hospital in Busan, Korea. They categorized the Q-statements using a 9-point scale. Using the PC-QUANL program, factor analysis was performed with the P-samples along an axis.
Results:
The families’ perceptions of the DNR proxy decision were categorized into three types. Type I, rational acceptance, valued consensus among family members based on comprehensive support from medical staff. Type II, psychological burden, involved hesitance in making a DNR proxy decision because of negative emotions and psychological conflict. Type III, discreet decisions, valued the patients’ right to self-determination and desire for a legitimate proxy decision. Type I included 18 participants, which was the most common type, and types II and III each included eight participants.
Conclusion
Families’ perceptions of DNR proxy decisions vary, requiring tailored care and intervention. We suggest developing and providing interventions that may psychologically support families.

Purpose:
Cancer patients need ongoing care from healthcare providers to maintain continuity of treatment. Much research has been conducted on digital health services for providing continuous management of discharged cancer patients. This review aimed to identify nurse-led digital health interventions for discharged cancer patients.
Methods:
This scoping review was conducted using JBI methodology. The population was post-discharge adult cancer patients, the concept was nurse-led digital health intervention, and the context was open. Databases including PubMed, Embase, CINAHL, Cochrane Library, KoreaMed, and RISS were searched.Data were summarized about the general characteristics of the article, participants, interventions, and outcomes.
Results:
Fifty-seven studies were included, with ten studies that focused on the elderly. One third of the participants included in this review had colorectal cancer (32.7%). Telephone was the most frequently used format, while the others were applications, the internet, and telemonitoring. The nurses’ main roles consisted of counseling, symptom monitoring, and education.
Conclusion
The development of nurseled digital health intervention for the elderly will be necessary, and studies using more diverse technologies will need to be conducted. Digital health interventions for post-discharge colorectal cancer patients could be applied in practice. Nurses should provide emotional support while providing digital health interventions.

BACKGROUND: The gene for chromodomain helicase/ATPase DNA binding protein 1-like (CHD1L) was recently identified as a target oncogene within the 1q21 amplicon, which occurs in 46% to 86% of primary hepatocellular carcinoma (HCC) cases. However, the prognostic significance of CHD1L in HCC remains uncertain. In this study, we investigated the roles of CHD1L in the prognosis of HCC. METHODS: We investigated the expressions of CHD1L in tumor tissue microarrays of 281 primary HCC patients who underwent surgical resection using immunohistochemistry. Prognostic factors of HCC were examined by univariate and multivariate analyses. The median follow-up period was 75.6 months. RESULTS: CHD1L expression was observed in 48 of the 281 HCCs (17.1%). CHD1L expression was associated with a younger age (p=0.033), higher Edmondson grade (p=0.019), microvascular invasion (p<0.001), major portal vein invasion (p=0.037), higher American Joint Committee on Cancer T stage (p=0.001), lower albumin level (p=0.047), and higher alpha-fetoprotein level (p=0.002). Multivariate analyses revealed that CHD1L expression (p=0.027), Edmondson grade III (p=0.034), and higher Barcelona Clinic Liver Cancer stage (p<0.001) were independent predictors of shorter disease-free survival. CONCLUSIONS: CHD1L expression might be a prognostic marker of shorter disease-free survival in HCC patients after surgical resection.

BACKGROUND/AIMS: The prognosis after surgical resection of hepatocellular carcinoma (HCC) remains poor because of a high rate of recurrence. Thus, it is crucial to identify patients with a high risk of recurrence after curative hepatectomy and to develop more effective and targeted treatment strategies to improve disease outcomes. In this study, we investigated the roles of metadherin (MTDH) in the prognosis of HCC. METHODS: We investigated MTDH expression using immunohistochemistry in tumor tissue microarrays of 288 primary HCC patients who underwent curative surgical resection. RESULTS: High MTDH expression was observed in 138 of the 288 HCC cases (47.9%). High MTDH expression was associated with a younger age (p<0.001), higher Edmondson grade (p<0.001), microvascular invasion (p<0.001), higher American Joint Committee on Cancer T stage (p=0.001), and higher alpha-fetoprotein level (p=0.003). Multivariate analyses revealed that high MTDH expression (p=0.014), higher Barcelona-Clinic Liver Cancer (BCLC) stage (p<0.001), and Edmondson grade III (p=0.042) were independent predictors of shorter disease-free survival (DFS). Higher BCLC stage (p<0.001) and Edmondson grade III (p=0.047) were also independent predictors of shorter disease-specific survival. CONCLUSIONS: High MTDH expression may be a prognostic predictor of shorter DFS in HCC patients after curative hepatectomy.

We report a case of cardiac lymphoma in a 40-year-old man, who had a mediastinal mass which was diagnosed as sclerosing mediastinitis pathologically. The mediastinal mass caused right pulmonary arterial stenosis. The patient developed myocardial hypertrophy and echocardiography showed restrictive physiology and severely decreased left ventricle ejection fraction, 6 months later. MRI showed global left ventricular myocardial hypertrophy and diffuse late gadolinium hyperenhancement after administration of contrast material. Thus, non-ischemic cardiomyopathy was suspected on MRI. However, pathology confirmed the myocardial abnormality as lymphoma after myocardial biopsy. Because a basal part of the left ventricle and global subendocardial myocardium were not involved on contrast-enhanced delayed MRI, the MRI abnormalities could be differentiated from amyloidosis and other myocardial diseases. The peculiar non-mass forming diffuse hypertrophy pattern of cardiac lymphoma has not been known in the MRI literature.

BACKGROUND: BCL9 enhances beta-catenin-mediated transcriptional activity regardless of the mutational status of the Wnt signaling components and increases the cell proliferation, migration, invasion, and metastatic potential of tumor cells. The goal of this study was to elucidate the prognostic significance of BCL9 protein expression in hepatocellular carcinoma (HCC) patients. METHODS: We evaluated BCL9 protein expression by immunohistochemistry in tumor tissue from 288 primary HCC patients who underwent curative hepatectomy. The impact of BCL9 expression on the survival of the patients was analyzed. The median follow-up period was 97.1 months. RESULTS: Nuclear BCL9 protein expression was observed in 74 (25.7%) of the 288 HCCs. BCL9 expression was significantly associated with younger age (p=0.038), higher Edmondson grade (p=0.001), microvascular invasion (p=0.013), and intrahepatic metastasis (p=0.017). Based on univariate analyses, BCL9 expression showed an unfavorable influence on both disease-free survival (DFS, p=0.012) and disease-specific survival (DSS, p=0.032). Multivariate analyses revealed that higher Barcelona Clinic Liver Cancer stage was an independent predictor of both shorter DFS (p<0.001) and shorter DSS (p<0.001). BCL9 expression tended to be an independent predictor of shorter DFS (p=0.078). CONCLUSIONS: BCL9 protein expression might be a marker of shorter DFS in HCC patients after curative hepatectomy.

Thymic adenocarcinoma is extremely rare. Although its histologic features have been occasionally reported, a lack of description of the cytologic features has hampered the prompt and accurate diagnosis of this condition. Herein, we describe the cytologic findings and histology of four aspiration cytology specimens of thymic adenocarcinoma. The specimens were obtained from primary tumors, metastatic lymph nodes, and pericardial effusions. All four specimens showed three-dimensional glandular clusters with a loss of polarity and nuclear overlapping. One specimen had extensive extracellular mucinous material. Three specimens contained tumor cells with intracytoplasmic vacuoles. While the specimen with extracellular mucin showed relatively mild cytologic atypia, other specimens exhibited more atypical cytologic changes: irregular nuclear membranes, a coarse chromatin pattern, and prominent nucleoli. The cytologic features were correlated with the histologic features in each case of enteric type thymic adenocarcinoma. The differential diagnosis included other thymic carcinomas, yolk sac tumors, and metastatic adenocarcinoma from the lung or colorectum.

Journal of Korean Medical Science 2018;33(15):e123-
BACKGROUND: Anaplastic lymphoma kinase tyrosine kinase inhibitors (ALK-TKIs) are usually effective in lung adenocarcinoma patients with anaplastic lymphoma kinase (ALK) rearrangement. However, even after a good response to ALK-TKI therapy, most patients acquire resistance to these agents. Histological transformation is one of several suggested mechanisms of acquired resistance to ALK-TKIs. The clinicopathologic features of four patients with ALK-expressing adenocarcinoma and neuroendocrine features were analyzed. METHODS: We selected combined neuroendocrine differentiation in pulmonary adenocarcinoma cases with positive ALK immunostaining. Neuroendocrine differentiation was confirmed by CD56 immunohistochemical stain. Additional ALK fluorescence in situ hybridization (FISH) study and epidermal growth factor receptor (EGFR) mutation tests were also performed. RESULTS: All four cases were positive for ALK immunohistochemistry and no EGFR mutations were detected. Interestingly, the results of ALK FISH assays showed rearrangement in only two cases. Three cases showed combined adenocarcinoma and neuroendocrine component without history of ALK-TKI administration; one of them was treated with crizotinib and experienced partial tumor regression. The remaining case had an adenocarcinoma at initial biopsy and she showed a partial response to crizotinib, and neuroendocrine changes were visible on second biopsy. Then she was treated with ceritinib and achieved a partial response. CONCLUSION: We suggest that ALK-rearranged adenocarcinoma with combined neuroendocrine component is responsive to ALK-TKIs. Moreover, even after neuroendocrine transformation as a result of resistance to ALK-TKIs, the tumor may have partial response to second generation ALK-TKIs.

Neural stem cells (NSCs) have the ability to self-renew and differentiate into multiple nervous system cell types. During embryonic development, the concentrations of soluble biological molecules have a critical role in controlling cell proliferation, migration, differentiation and apoptosis. In an effort to find optimal culture conditions for the generation of desired cell types in vitro, we used a microfluidic chip-generated growth factor gradient system. In the current study, NSCs in the microfluidic device remained healthy during the entire period of cell culture, and proliferated and differentiated in response to the concentration gradient of growth factors (epithermal growth factor and basic fibroblast growth factor). We also showed that overexpression of ASCL1 in NSCs increased neuronal differentiation depending on the concentration gradient of growth factors generated in the microfluidic gradient chip. The microfluidic system allowed us to study concentration-dependent effects of growth factors within a single device, while a traditional system requires multiple independent cultures using fixed growth factor concentrations. Our study suggests that the microfluidic gradient-generating chip is a powerful tool for determining the optimal culture conditions.
