[A Multicenter randomized comparative study of dementia nursing practice skills development programs for nurses in acute care hospitals: A Comparison of person-centered care and dementia-type-specific programs].

PURPOSE: The present multicenter randomized controlled trial explored the effectiveness of a person-centered care program (intervention group) and a dementia-type-specific program (control group) for nurses in acute-care hospitals. METHODS: Seven hospitals in Prefecture A were randomly allocated to two groups (an intervention group and a control group), and a study of these groups was conducted from July 2021 to January 2022. RESULTS: A total of 158 participants were included in the study: 58 in the control group and 100 in the intervention group. In a comparison of assessment values immediately after the course, three months later, and six months later for both the intervention and control groups, "expertise in dementia nursing," "medical expertise in dementia, " and "confidence in nursing older people with dementia" were all significantly higher than before the course. Significant improvements in the intervention group's "knowledge of dementia" and "sense of dignity" on the ethical sensitivity scale were found immediately after the course compared to baseline, three months later, and six months later and were also significantly greater than the control group in terms of the amount of change. In the control group's "unique care tailored to cognitive function and the person," there were significant improvements in the ratings immediately after the course and three and six months after the course compared to baseline, with significantly greater amounts of change than in the intervention group. CONCLUSION: The person-centered care program for nurses led to improvements in the knowledge about dementia and awareness of the dignity of ethical sensitivity. In addition, the type of dementia program had a significant influence on medical knowledge and unique care tailored to the cognitive function and the individual patient. Further outcome evaluations of physical restraint rates as a quality of care in nursing practice are needed.

Practicality Assessment of the Improved ICT-Based Dementia Care Mapping Support System.

OBJECTIVES: Authors have developed an ICT (Information-Communication Technology)-based Dementia Care Mapping (DCM™) support system and assessed its usefulness previously using videos. The aim of this study is to evaluate practicality of the improved support system by actual mapping. METHODS: We obtained highly reliable mapping data by a team of 3 mappers (M1, M2, and M3), who mapped 5 elderly people with dementia continuously over 4 hours in 2 sites. M1 mapped by conventional paper-based DCM™, while M2 and M3 mapped using the support system. Collected mapping data (n = 8, total of 232.5 hours = 2790 time frames) were compared. RESULTS: The concordance rates between M1 and M2/M3 were over 70%; the required level for DCM™ evaluation purposes, with 1 exception. We also obtained users' positive ratings regarding the system usability. CONCLUSION: Practicality of the ICT-based DCM™ support system was confirmed for evaluation purposes, demonstrating the system is ready for practical use.

Clinical and radiological impact of liver transplantation for brain in cirrhosis patients without hepatic encephalopathy.

OBJECTIVE: To elucidate the effect of liver transplantation (LT) on brain dysfunctions in cirrhotic patients who had no clinical evidence of hepatic encephalopathy (HE), we performed a prospective study of voxel-based diffusion tensor imaging (DTI) and detailed cognitive examination. METHODS: We assessed 12 consecutive patients as transplant candidates by DTI, with neurological and cognitive examinations just before and at 6 months after LT. RESULTS: After LT, cirrhotic patients showed significant improvement in visual reproduction, digit symbol, digit span, Stroop test, and Trail-making test scores, suggesting recovery of frontal-temporal function. As for voxel-based DTI, increased mean diffusivity (MD) and reduced fractional anisotropy (FA) values were found before LT in the frontal and temporal lobes of cirrhotic patients. After LT, the unusual FA and MD values observed in the frontal and temporal lobes preoperatively were significantly reduced. CONCLUSION: End-stage cirrhotic patients without clinical evidence of HE showed increased MD and decreased FA values in both frontal and temporal lobes. These parameters improved after LT, in line with cognitive function. MD and FA values might be of value as a biomarker in end-stage cirrhotic patients for investigating brain tissue dysfunctions and evaluating the efficacy of LT.

[Case of acquired hepatocerebral degeneration with prominent improvement of parkinsonism and cognitive deficits after living-donor liver transplantation].

A 53-year-old woman visited us for a neurological consultation before her liver transplantation. She had a history of primary biliary cirrhosis that began at 37 years of age. She showed falling episodes and met with a traffic accident at 52 years old. Since then, her symptoms had worsened. The neurological examination showed masked face, rigidity on bilateral arms and legs, and lack of balance. Her Mini-Mental State Examination Score was 28/30, but she suffered from loss of memory and had trouble with executive function in detailed examinations. Her T(1) weighted image showed hyperintensity in bilateral globus pallidus, putamen, dentate nucleus and cerebral peduncle. There was a significant improvement in intellectual function and neurological signs 6 months after her orthotopic liver transplantation. In addition, post-liver transplantation images showed a decrease in the area of hyperintensities. This case suggests that even in a patient with severe liver cirrhosis a complete cure of neurological manifestations can be obtained after the liver transplantation.

Behavioral changes in early ALS correlate with voxel-based morphometry and diffusion tensor imaging.

BACKGROUND: Amyotrophic lateral sclerosis (ALS) is a multisystem disorder with impairment of frontotemporal functions such as cognition and behavior, but the behavioral changes associated with ALS are not well defined. METHODS: Twenty-one consecutive patients with sporadic ALS and 21 control subjects participated in the study. The Frontal System Behavior Scale (FrSBe) was used to assess behavioral change. Voxel-based morphometry (VBM) and voxel-based analysis of diffusion tensor images (DTI) were performed to explore the associations of brain degeneration with behavior. All patients were evaluated before the notification of ALS. RESULTS: FrSBe scores of ALS patients before notification were significantly increased compared to those of control subjects. Moreover, the FrSBe Apathy score of ALS patients significantly changed from pre- to post-illness (P<0.001). The severity of apathy was significantly correlated with atrophy in the prefrontal cortex, especially in the orbitofrontal (P=0.006) and dorsolateral prefrontal (P=0.006) cortices in VBM, and in the right frontal gyrus (P<0.001) in DTI. CONCLUSIONS: ALS patients exhibited apathy during the early course of the illness, the severity of which was significantly associated with frontal lobe involvement. These findings support the view that a continuum exits between ALS and frontotemporal dementia.
