  • This review article explores the psychological characteristics, comorbid mental disorders, and psychosocial assessments throughout the solid organ transplant journey, spanning the pre-transplant, peri-transplant, and post-transplant phases for transplant recipients. The psychological burden and anxiety in the pre-transplant phase are high for organ failure patients with complex physical difficulties who are deciding to undergo transplantation and are on the waiting list. The pre-transplant psychosocial evaluation covers various aspects, including the patient's readiness, awareness of, and commitment to transplant treatment, medical compliance, psychopathological conditions such as cognitive function and personality disorders, lifestyle factors, including substance abuse, as well as various psychosocial factors like social support. During the peri-transplant phase, mental health problems such as postoperative delirium should be carefully recognized and addressed. After transplantation, it is essential to assist patients in coping with the various stressful experiences they encounter, manage psychiatric symptoms such as depression, anxiety, and insomnia, and improve treatment adherence and quality of life during long-term care for the transplanted organ. Managing psychiatric problems in post-transplant patients requires a deep understanding of immunosuppressant medications and a keen awareness of associated risks, including adverse effects and potential drug interactions. This comprehensive review emphasizes the significance of proactive mental health care and psychosocial evaluation, highlighting the necessity of a multidisciplinary approach to enhance the quality of life and overall success of transplant patients throughout all phases of transplantation.

  • For a large sclase production of genetically identical or cloned animals, the effect of cryopreservation by vitrification on the post-thaw viability of nuclear transplant rabbit embryos were investigated. The embryos of 16-cell stage were collected from the mated does at 48 hours post-hCG injection, and they were synchronized to G1 phase of 32-cell stage were injected into enucleated recipient cytoplasms by micromanipulation. After culture until 20h post-hCG injection, the nuclear transplant oocytes were electrofused and activated by electrical stimulation. After in vitro culture for 48h, the nuclear transplant embryos developed to morula stage were cryoperserved with EFS solution by vitrification method. The forzen nuclear transplant embryos were thawed and cultured for 72h and the nuclear transplant of blastomeres under a fluorescence microscopy. The in vitro development to blastocyst of intact-fresh and intact-frozen 16-cell embryos was found to be 96.9 and 63.9%, respectively. The in vitro development to blastocyst of nuclear transplant and frozen-thawed nuclear transplant embryos was found to be 74.5 and 42.9%, respectively. Also, their mean blastomere numbers and mean cell cycles/day was 153 and 105, 145 and 1.34, respectively. From the above results it was concluded that the present cryopreservation by vitrification of nuclear transplant rabbit embryos might be useful though was decreased significantly.

  • Marked declines in seagrass meadows are increasingly being reported from coasts around Korea and many regions of the world. The transplantation of seagrasses has been attempted to mitigate and control their degradation from a range of anthropogenic factors. In this study, Zostera marina shoots, which were collected from a donor bed in Koje Bay, were transplanted in Jindong Bay in December 2004. In 2008, a comparative investigation of shoot morphology, growth, and reproduction strategy of Z. marina was carried out between the donor and transplant sites to assess their adaptation success. Shoot height, individual shoot weight, and leaf productivity at the transplant site were significantly greater than those at the donor site. However, below-/aboveground tissue ratio was significantly lower at the transplant site compared to the donor site. Z. marina survival was maintained through vegetative reproduction, while peak season for lateral shoot recruitment was late winter for both donor and transplant site populations. However, vegetative reproduction mainly occurred during late winter and spring at the transplant site, whereas lateral shoots were evident across all seasons except late spring in the donor site. More pronounced seasonal variations were found at the transplant site compared to the donor site. These results indicate that Z. marina populations at the two sites possess distinct phenotypic variations induced by different environmental conditions, and Z. marina transplants have adapted well to the new transplant environment.

  • Purpose: This study was performed to identify the pre-and post-transplant nutritional assessment for patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT). Methods: The subjects of this study were 25 patients undergoing allogeneic HSCT. The data collection was performed from January 31st to March 31st, 2011. The Patient-Generated Subjective Global Assessment (PG-SGA), anthropometrics and biochemical test were collected from the time they entered the isolation unit until they left. Results: Pre-transplant nutritional assessment status indicated moderate malnutrition which scored $7.32{\pm}1.68$ in PG-SGA. There were 22 patients (88.0%) with moderate malnutrition and 3 patients (12.0%) with severe malnutrition. Post-transplant nutritional assessment indicated severe malnutrition status which scored $11.92{\pm}3.26$ in PG-SGA. Pre-and post-transplant nutritional assessment displayed significant differences (p<.001) in PG-SGA score. Hematopoietic stem cell transplantation led to a deterioration of patients' nutritional status. Pre-transplant patients were already in malnutrition status and patients undergoing allogeneic HSCT were at risk for malnutrition. Conclusion: Pre-and post-transplant patients were categorized as having undernutritional and malnutritional status. Pre-transplant nutrition status impacted on post-transplant nutritional status. Health care personnel should pay attention to patient's nutrition status when undergoing allogeneic HSCT with appropriate nutritional assessment tools.

  • Purpose: Compliance in kidney transplant recipients is critical for a positive prognosis. Especially compliance with medications after kidney transplantation is a major health care issue with implications for graft rejection and graft loss. But the definition of compliance in transplantation varies among centers. The purpose of this study was to clarify the concept of compliance in kidney transplant recipients. Methods: A literature search was conducted using RISS, MEDLINE, CINAHL. The concept analysis was guided by the methodology posited by Walker and Avant. Results: In this study, we found the attributes of the concept: 'compliance with immunosuppressive medication', 'compliance with follow-up', 'compliance with early detection of graft rejection and complication', and 'compliance with prevention of complication'. The antecedents of 'compliance in kidney transplant recipients' included 'having a kidney transplant surgery' and 'normal function of transplanted kidney'. The consequences of 'compliance in kidney transplant recipients' included 'affecting the function of the transplanted kidney' and 'affecting the health of kidney transplant recipients. Conclusion: This study may contribute to the development of tools for measuring compliance in kidney transplant recipients, as well as benefit nursing interventions research to increase compliance in kidney transplant recipients.

  • Aim: To analyze the significance of different clinical factors for prognostic prediction in diffuse large B-cell lymphoma (DLBCL) patients. Methods: Two hundred and twenty-seven DLBCL patients were retrospectively reviewed. Patients were managed with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) regimen or rituximab plus the CHOP (RCHOP) regimen. Results: Lactate dehydrogenase (LDH), ${\beta}2$-microglobulin (${\beta}2$-M), B symptoms, Ann Arbor stage and genetic subtypes were statistically relevant in predicting the prognosis of the overall survival (OS). In the CHOP group, the OS in patients with germinal center B-cell-like (GCB)(76.2%) was significantly higher than that of the non-GCB group (51.9%, P=0.032). With RCHOP management, there was no statistical difference in OS between the GCB (88.4%) and non-GCB groups (81.9%, P=0.288). Conclusion: Elevated LDH and ${\beta}2$-M levels, positive B symptoms, Ann Arbor stage III/IV, and primary nodal lymphoma indicate an unfavorable prognosis of DLBCL patients. Patients with GCB-like DLBCL have a better prognosis than those with non-GCB when treated with the CHOP regimen. The RCHOP treatment with the addition of rituximab can improve the prognosis of patients with DLBCL.

  • Purpose: This study was done to investigate the degree of self-efficacy, transplant-related knowledge, and other factors affecting compliance with a therapeutic regimen for liver transplant recipients. Methods: Participants were 140 patients who had received a liver transplant at a tertiary hospital in Y City, Gyeongnam Province and made regular hospital visits as outpatients. A self-report questionnaire was used to collect the data and collection was done from December 4, 2017 to January 26, 2018. Data were analyzed using frequencies, percentages, means, and standard deviations, and t-test, ANOVA, Pearson's correlation coefficients. Multiple linear regression was performed using SPSS/WIN 21.0 program. Results: Participants scored $113.29{\pm}20.95$ (out of 150) on self-efficacy, $16.38{\pm}3.62$ (out of 18) on transplant-related knowledge, and $148.30{\pm}31.06$ (out of 200) on compliance with the therapeutic regimen. Analyzed of correlations among participant's self-efficacy, transplant-related knowledge, and compliance with the therapeutic regimen showed a significant positive correlation between self-efficacy and compliance with the therapeutic regimen (r=.64, p=.001), but no significant correlations were found between self-efficacy and transplant-related knowledge (r=-.01, p=.912) or between transplant-related knowledge and compliance with the therapeutic regimen (r=.06, p=.458). Multiple regression analysis showed that factors affecting compliance with the therapeutic regimen were state of re-transplantation (${\beta}=.17$, p=.016) and self-efficacy (${\beta}=.53$, p=.001). Conclusion: There is a need to apply a differentiated nursing intervention program considering the differences in patients' self-efficacy, transplant-related knowledge, and compliance with the therapeutic regimen.

  • Purpose: The purpose of this study was to identify factors influencing quality of life in kidney transplant recipients and to understand the concrete pathway of influence and the power of each variable, so that integrated prediction model to promote the quality of life of kidney transplant recipients could be developed. Methods: The sample was composed of 218 patients in follow-up care after a kidney transplant in one of 4 university hospitals in the Honam area. A structured questionnaire was used and the collected data were analyzed for fitness, using the LISREL program. Results: This model was concise and extensive in predicting the quality of life of kidney transplant recipients. Conclusion: The research verified the factors influencing quality of life for kidney transplant recipients and it verified that direct factors such as perception of health state, compliance, self-efficacy, stress and indirect factors such as self-efficacy and social support can be important factors to predict the quality of life for recipients. Moreover, those variables represent 87% of variance in explaining quality of life in a prediction model so that the variables can be utilized to predict quality of life for kidney transplant recipients.

  • Production of calves after transfer of nuclear transplant embryos is the latest technology to be applied in commercial livestock breeding. The objective of this study was to establish an efficient procedure to produce offsprings from nuclear transplant embryos. The fusion rates (72.7% vs. 80.8%), cleavage rates (62.5% vs. 71.4%) and rates of development in vitro (12.0% vs. 15.2%) of nuclear transplant embryos were not significantly different between 30 and 40h maturation age of cytoplast. The in vivo and in vitro-derived embryos as nuclei donor were used in this system of bovine nuclear transplantation. Fusion rates of nuclear transplant embryos were not significantly different between in vivo and in vitro-derived embryos (73.0 and 79.2%, respectively). The percentage of embryos reaching the morulae or blastocysts were 21.8% for in vivo-derived embryos and 11.9% for in vitro-derived embryos (p<0.01). Pregnancy rates after embryo transfer of nuclear transplant embryos were not significantly different between in vivo and in vitro-derived embryos (45.9 and 40.5%, respectively). However, calving rates after embryo transfer of nuclear transplant embryos were significantly higher in the in vivo-derived embryos than in vitro (p<0.01). Further research for age of cytoplast and use of in vitro-derived embryos as nuclei donor is required in this system. In conclusion, these results clearly show that the use of in vitro-derived oocytes as recipient cytoplast can improve the nuclear transplant system for genetic progress in cattle.
