This study aimed to clarify the relationship between the level of support from supervisors and colleagues and job satisfaction among nurses working in care facilities for older persons. Using a cross-sectional design, we analyzed the responses of 295 nurses in long-term care facilities in Japan to a questionnaire survey. The surveyed items included the nurses' satisfaction with their current job (the dependent variable), and the degree of support from supervisors and colleagues. Of the 295 nurses, 166 (56.3%) were satisfied with their nursing jobs. Additionally, 125 (42.4%) nurses had low support from both supervisors and colleagues, 110 (37.3%) had high support from either supervisors or colleagues, and 60 (20.3%) had high support from both. There was a positive association between support from supervisors and nurses' satisfaction. Furthermore, based on the criterion of low support from supervisors and colleagues, high support from either or both was significantly associated with nurses' satisfaction (an odds ratio of 2.04 in the case of support from either and 4.02 in the case of support from both).

In this study, we focused on osteoblasts and osteoclasts, which are essential for bone remodeling and regeneration. Proliferation assay, boyden chamber, and wound healing assay were performed on MC3T3-E1 and RAW264 cells. Osteogenic differentiation assay was performed on MC3T3-E1 cells, and osteoclast differentiation assay was performed on RAW264 cells. Samples collected from distraction osteogenesis model mice were subjected to micro-computed tomography analysis and tissue staining.

We also found that Y-27632 promoted cell motility and osteoclast differentiation in the osteoclast precursor RAW264 cells. In vivo experiments showed that the local administration of Y-27632 in a mouse distraction osteogenesis model promoted bone formation and increased the number of osteoblasts and osteoclasts in the distraction osteogenesis gap.

A new pneumatic lymphatic drainage (PLD) device consisting of multiple round air chambers located according to the lymphatic pathways was collaboratively developed with a company. The device's air chambers simulate a therapist's manual lymphatic drainage (MLD) movements; however, the efficacy of this novel PLD is unknown. This feasibility study evaluated the lymphatic flow change by lymphoscintigraphy under PLD in 18 lower limbs with lymphedema and showed that the PLD enhanced lymphatic flow, especially in limbs with mild lymphedema. Previous reports have shown that in patients with lymphedema, improving lymphatic flow requires IPC with a high pressure (~100 mmHg). Although the PLD in this study only utilized mild pressure (50 mmHg) for 10 min, the tracer injected into the distal leg moved stably to the inguinal region.

Gratitude, as one of the positive psychological factors, might have a protective effect against presenteeism. This is because gratitude can reduce stress, increase support from others, improve the workplace atmosphere, and enhance self-efficacy. Therefore, we hypothesized that higher trait gratitude (individual differences in the tendency to feel gratitude) and higher frequency of gratitude expression would be associated with lower levels of presenteeism. In 2022, a cross-sectional study was conducted with workers in Tsukuba City. The outcome variable was the Single-item Presenteeism Question, which is an indicator of presenteeism.
