[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.

The efficacy, safety, and pharmacokinetics of biapenem administered thrice daily for the treatment of pneumonia in the elderly.

Biapenem has been widely used to treat bacterial pneumonia; however, there is little information concerning its efficacy and safety in elderly patients. Based on pharmacokinetic-pharmacodynamic theory, administration of biapenem thrice rather than twice daily would be expected to be more effective because of longer time above the minimum inhibitory concentration. In this study, we aimed to evaluate the efficacy, safety, and pharmacokinetics of biapenem (300 mg) administered thrice daily in pneumonic patients aged 65 years or older. Biapenem was effective in 22 of 25 patients, as assessed by the improvement in clinical symptoms and/or the eradication of the causative organisms, and caused no serious adverse events. The pharmacokinetic profile was established based on simulations using a modeling program. Among 17 patients whose causative organisms were detected, time above the minimum inhibitory concentration was estimated to be 100% in 16 patients, all of whom showed clinical improvement. The results of this study confirmed the efficacy and safety of 300 mg of biapenem administered thrice daily for the treatment of pneumonia in elderly patients.

[In vitro susceptibilities to levofloxacin and various antibacterial agents of 12,919 clinical isolates obtained from 72 centers in 2007].

We have reported in this journal in vitro susceptibilities of clinical isolates to antibiotics every year since 1992. In this paper, we report the results of an analysis of in vitro susceptibilities of 12,919 clinical isolates from 72 centers in Japan to selected antibiotics in 2007 compared with the results from previous years. The common respiratory pathogens, Streptococcus pyogenes, Streptococcus pneumoniae, Moraxella catarrhalis and Haemophilus influenzae maintained a high susceptibility to fluoroquinolones (FQs). The resistance of S. pyogenes to macrolides has been increasing every year and this was especially clear this year. Most strains of Enterobacteriaceae except for Escherichia coli showed a high susceptibility to FQs. Almost 30% of E. coli strains were resistant to FQs and the resistance increased further this year. FQs resistance of methicillin-resistant Staphylococcus aureus (MRSA) was approximately 95% with the exception of 45% for sitafloxacin (STFX). FQs resistance of methicillin-susceptible S. aureus (MSSA) was low at about 10%. FQs resistance of methicillin-resistant coagulase negative Staphylococci (MRCNS) was higher than that of methicillin-susceptible coagulase negative Staphylococci (MSCNS), but it was lower than that of MRSA. However, FQs resistance of MSCNS was higher than that of MSSA. FQs resistance of Enterococcus faecalis was 22.5% to 29.6%, while that of Enterococcusfaecium was more than 85% except for STFX (58.3%). In clinical isolates of Pseudomonas aeruginosa derived from urinary tract infections, FQs resistance was 21-27%, which was higher than that of P. aeruginosa from respiratory tract infections at 13-21%, which was the same trend as in past years. Multidrug resistant strains accounted for 5.6% in the urinary tract and 1.8% in the respiratory tract. Acinetobacter spp. showed high susceptibility to FQs. The carbapenem resistant strains, which present a problem at present, accounted for 2.7%. Neisseria gonorrhoeae showed high resistance of 86-88% to FQs. The results of the present survey indicated that although methicillin-resistant Staphylococci, Enterococci, E. coli, P. aeruginosa, and N. gonorrhoeae showed resistance tendencies, and other species maintained high susceptibility rates more than 90% against FQs, which have been used clinically for over 15 years.
