Living donor liver transplantation(LDLT) has been considered as a valuable approach to shortening waiting time. The objectives of this study were to investigate the feasibility of utilizing donors older than 50 years in LDLT and to evaluate the graft function and recipient survival.METHODS: All LDLT cases(n=159) were divided into the older(donor age ≥50 years, n=10) and younger(donor age 〈50 years,n=149) donor groups. Donor graft and recipient condition pre-,intra- and post-operation were compared between the two groups.In particular, graft functions and recipient survivals were analyzed.RESULTS: The median donor age was 58.5(52.5-60.0) years in the older donor group and 25.0(23.0-32.0) in the younger donor group. There was no significant difference in cold ischemic time, anhepatic phase and operation time between the older and younger donor groups(P〉0.05). However, the volume of red blood cell transfused in operation was greater in the older donor group than in the younger donor group(1900 vs 1200 m L, P=0.023). The 1-, 3- and 5-year graft survival rates were 90%, 80% and 80% for the older donor group, and 92%, 87% and 87% for the younger donor group, respectively(P=0.459).The 1-, 3- and 5-year survival rates were 100%, 90% and 90% for recipients with older grafts, and 93%, 87% and 87% for those with younger grafts, respectively(P=0.811).CONCLUSION: It is safe for a LDLT recipient to receive liver from donors older than 50 years, and there is no significant adverse effect on graft function and long-term patients’ survival.展开更多

This study aimed to evaluate the quality of healthcare services in Japan’s long-term care facilities and identify the structural and process indicators associated with the facilities’ outcome indicators. Methods: This retrospective study assessed changes in residents’ abilities to participate in physical activities, their cognitive function, and their vulnerability to injuries. From 2012 to 2013, we collected information on the healthcare services at 1067 long-term care facilities registered with Japan’s Welfare, Health and Medical Care Information Network in the Welfare and Medical Service Agency. We examined 12 structural indicators, 26 process indicators, and 7 outcome indicators. We used multivariate linear regression models adjusted to analyze relationships between outcome indicators and structural or process indicators. Results: Residents’ activity and cognitive function indicators either improved by 80% - 90% or were maintained for one year. The Geriatric Functional Independence Measures, the Barthel Index, and holding conferences related to care were all considered activities of daily living. Three adverse events—tumbles and falls, behavioral problems, and aimless wandering or leaving the facility without permission—were factors that restricted residents’ behavior and number of residents per care staff member. Conclusions: Maintaining or improving levels of independence and cognition in daily living requires a care process system that enables ongoing monitoring of residents’ activities of daily living and cognitive functioning. Ensuring the safety of residents and improving the quality of care in long-term care facilities without securing adequate care staff are not possible.展开更多

Metaphorical use of address terms will be one focus of this paper. Functions of address terms have been investigated a lot, but emotional functions are less emphasized. Therefore, this paper will make a tentative study of how people metaphorically use address terms to express the addresser's affect towards the addressee within the framework of Appraisal Theory.展开更多

Several special cases representing equations from different categories are investigated for their roots.

Among 174 patients undergoing transplantation for hematologic malignancies between May 1994 and December 2004, 81 long-term survivors were evaluated. Pulmonary function tests (PFTs) were performed before conditioning, 3 months and 1 year after transplantation, and then annually. Eight patients (10%) had abnormal pulmonary function before transplantation, but this was not associated with late changes in PFTs. Patients with chronic graft-versus-host disease (GVHD) showed a significant decline of lung function after 3 years when compared with patients without chronic GVHD. Abnormal pretransplantation lung function was associated with pulmonary chronic GVHD according to National Institutes of Health criteria (score 0, n = 58;score 1, n = 14;score 2, n = 6;score 3, n = 3). Five patients with late-onset noninfectious pulmonary complications showed a decline of lung function at 1 year after transplantation. Only chronic GVHD was significantly related to late-onset noninfectious pulmonary complications. In conclusion, abnormal lung function before transplantation may be associated with a decline in pulmonary function within 1 year after transplantation, but late-onset noninfectious pulmonary complications could not be predicted from pretransplantation lung function.展开更多

However, long-term outcomes of living kidney donors have not been well understood. Because securing the safety of the donor is essential to the continued success of this procedure, we reviewed articles discussing long-term outcomes of living kidney donors. Most studies found no decrease in long-term survival or progressive renal dysfunction in previous kidney donors. Moreover, the prevalence of hypertension was comparable to that expected in the general population, although some did report otherwise. Urinary protein showed small increases in this population and was associated with hypertension and a lower glomerular filtration rate. Quality of life following living kidney donation seems to be better than the national norm. We also encountered several reports of ESRD in previous living kidney donors. Regular follow-up of kidney donors is recommended and future controlled, prospective studies will better delineate risk factors which cause health problems following living kidney donation.展开更多

We investigated outcome indicators, such as changes in dietary intake and swallowing function levels of residents, and clarified which structural and process indicators were associated with the outcome indicators. This was a retrospective study, analyzing information on healthcare services from 1067 long-term care facilities during the fiscal year 2012, sampled from among those registered with the Welfare, Health and Medical Care Information Network of the Welfare and Medical Service Agency in Japan. Five outcome indicators were identified. Next, we examined the relationships between the outcome indicators and structural or process indicators using a multivariate linear regression model, adjusting for facility type. The findings showed how the five outcome indicators were used in long-term care facilities over a period of one year and determined the independent predictors of these outcome indicators. The amplification of dietary function 1 was associated with “assessment of oral functions using a feeding and swallowing assessment checklist every three months”, “holding care conferences related to ingestion and swallowing every three months”, and “maintaining a 1:2 ratio for meal-time assistants to residents”. To improve the quality of care, it is necessary to increase the number of staff (e.g., to provide meal assistance to residents) and to understand changes in the residents’ status through accurate assessment and monitoring.展开更多
