Objectives: The aim of this study was to investigate the association between the Rehabilitation Activity Time score (RATs)—a score based on the level and duration of rehabilitation activities—of ventilated patients in the intensive care unit (ICU) and activities of daily living (ADL) dependence at discharge.Methods: This retrospective, single-center study evaluated patients aged >18 years who underwent mechanical ventilation in the ICU for at least 48 h. The patients were categorized into the low- and high-dose rehabilitation groups based on the median RATs. The primary outcome was the rate of ADL dependence at discharge, defined as a Barthel index of <70. The association between low or high doses of rehabilitation and the primary outcome was assessed using multiple logistic regression analysis adjusted by baseline factors.Results: The rate of ADL dependence at discharge was significantly lower in the high-dose rehabilitation group (low dose 81% vs. high dose 22%, P<0.001). Multivariate analysis showed a significantly lower ADL dependence at discharge among those who received high-dose rehabilitation (P<0.001). Increased RATs during the entire ICU admission period and during ICU admission after meeting the criteria for physiological stability was significantly associated with lower ADL dependence at discharge (P<0.001). Moreover, a higher RATs from low-level activity before meeting the criteria for physiological stability also showed a significant association with lower ADL dependence at discharge (P=0.047).Conclusions: ADL dependence was significantly lower among those who underwent high-dose rehabilitation. The RATs was consistently associated with ADL dependence at discharge.

Objectives: This study investigated the effect of early mobilization [EM; physical rehabilitation with the intensity needed to sit on the edge of the bed started within 5 days of intensive care unit (ICU) admission] in relation to improvements in gait independence and other clinical outcomes.Methods: This retrospective single-center study evaluated patients aged at least 18 years who stayed in the ICU for at least 48 h and were categorized into EM and late mobilization (LM; physical rehabilitation started more than 5 days after ICU admission) groups. Outcomes were compared after adjusting for 20 background factors by propensity score matching and inverse probability of treatment weighting. The primary outcome was independent gait at discharge. The secondary outcomes were medical costs, 90-day survival, and durations of ICU and hospital stays.Results: Of 177 patients, 85 and 92 were enrolled in the EM and LM groups, respectively. Propensity score matching created 37 patient pairs. There was no significant difference in the 90-day survival rate (P=0.308) or medical costs (P=0.054), whereas independent gait at discharge (P=0.025) and duration of hospital stay (P=0.013) differed significantly. Multivariate logistic regression analysis showed that EM was independently associated with independent gait at discharge (P=0.011) and duration of hospital stay (P=0.010) but was not associated with 90-day survival (odds ratio: 2.64, 95% confidence interval: 0.67–13.12, P=0.169).Conclusions: Early mobilization in the ICU did not affect 90-day survival and did not lower medical costs but was associated with independent gait at discharge and shorter hospital stays.

The genetic structure of Streaked Shearwater Calonectris leucomelas, a seabird breeding on islands around Japan, was investigated using nuclear microsatellite markers at four breeding colonies located in three geographically distinct areas (Pacific Ocean, Sea of Japan, and Seto Inland Sea). To investigate independently natal and breeding dispersal patterns, we analyzed records of recoveries of birds banded around Japan over a 30-year period from 1971 to 2020. The genetic marker analysis showed little differentiation among the breeding sites and a lack of population structure. In contrast, banding data presented few examples of natal and breeding dispersal and a much greater number of natal/breeding philopatry cases. Although further research is needed to understand the discrepancy between the genetic properties and recapture patterns of banded birds, some possible reasons are suggested: actual dispersal events may not have been fully detected by the banding research, thus, underestimating dispersal frequency; rare dispersal events may have functioned to reduce the genetic structure; and/or breeding colonies of this species might have been established recently, thus genetic markers may not be indicative of current dispersal patterns. In conclusion, our results indicate ongoing gene flow and/or strong historical association in this species.

The seasonal variation in home range size of one male and one female Iriomote Cat Prionailurus bengalensis iriomotensis was studied by radio-tracking and automatic photography on Iriomote Island, Japan. The study was conducted in the Shirahama area located in the western part of the island. Shirahama provides a small area of suitable lowland habitat (<50 m a.s.l.) for the Iriomote Cat. Two individuals, one male and one female, were confirmed to be resident in this area. The periodical home range size of the male was 1.24 ± 0.41 km2 and that of the female was 1.30 ± 0.54 km2 throughout the year, with no significant difference between them. We compared the results of these observations with those from another area of suitable habitat in Funaura and discussed what factors may affect male home range size. The home range of the male cat in Shirahama was found to be only half the size of that of males in Funaura, though it showed similar seasonal fluctuation. The home ranges of females were similar in the two areas. Our results provide empirical confirmation of the influence of the number and distribution of females on male home range size in a solitary felid.
