ABSTRACT
Purpose@#The purpose of this study was to examine the knowledge, caregiving performance, stress levels, and mental health of family caregivers of terminal cancer patients with delirium, insofar as these characteristics are relevant for delirium. @*Methods@#Between May 1, 2019, and June 1, 2020, 96 family caregivers of terminal cancer patients with delirium completed a structured survey, the results of which were analyzed. @*Results@#The average correct answer rate for delirium-related knowledge was 53.2% across all subcategories, which included knowledge of causes (41.5%), symptoms (65.4%), and caregiving (51.7%).The average score for family caregivers’ performance of caregiving for delirium was 2.60 ±0.5, with subcategories including caregiving for patients without delirium (2.16±0.95), caregiving for patients with delirium (2.84±1.01), and stress related to caregiving for delirium (39.88±16.55), as well as categories such as patient-related caregiving (44.32±28.98), duty-related caregiving (44.21±30.15), and interpersonal relationship-related caregiving (22.35±25.03). For mental health, the average score among family caregivers was 1.96± 0.70, with the highest score being for the category of additional items (2.28±0.84). Family caregivers of patients with hyperactive delirium as the delirium subtype had higher scores for caregiving performance than caregivers of patients with mixed delirium. @*Conclusion@#Scores for the delirium-related knowledge and caregiving performance of family caregivers were low, while their caregiving stress levels were high due to their lack of knowledge and experience. This indicates the importance of delirium-related education for family members of patients with delirium and the necessity of developing nursing intervention programs to help manage stress and promote mental health among family caregivers.

ABSTRACT
PURPOSE: To investigate the effects of transglutaminase in the environment of extracellular matrix on perichondrocyte in alginate culture. MATERIALS AND METHODS: Perichondrocyte cells were isolated from articular cartilage of New Zealand white rabbits by enzymatic digestion and maintained in monolayer culture. After 7 days, the cells were trypsinized and cultured in an alginate bead system. Four groups of the alginate beads were prepared as follow: containing 1 mg/ml of transglutaminase, 10 microgram/ml of fibronectin, mixture of 1mg/ml of TGase and 10 microgram/ml of fibronectin and only perichondrocytes as a control group. Cell proliferation was measure by [Methyl-3H] Thymidine uptake, and proteoglycan synthesis was measure by [35S] Sulfate uptake. The gene expression of integrin-alpha5, integrin-beta1 and type II collagen was analyzed by reverse transcription-polymerase chain reaction. Safranin-O staining was utilized for histological assessment of proteoglycan in extracellular matrix. One-way ANOVA was used to analyze the results statistically. RESULTS: Mixture of transglutaminase and fibronectin exhibited high synthesis rates of proteoglycan and active cell proliferation compared with other groups. The gene expression of type II collagen did not show significant difference between groups. The gene expression of integrin-alpha5 was down-regulated in all groups with time. The gene expression of integrin-beta1 was not down-regulated with time only in mixture of transglutaminase and fibronectin. Histological staining of the secretions by Safranin-O staining was in agreement with the data of proteoglycan synthesis, and Safranin-O staining showed that more cell-to-cell aggregates is developed in the mixture of transglutaminase and fibronectin. CONCLUSION: Mixture of transglutaminase and fibronectin can stimulate chondrocyte proliferation and proteoglycan synthesis, and integrin seems to modulate such interactions.
