RESUMO
OBJECTIVES: Although horticultural therapy has been used successfully to reduce neuropsychiatric symptoms in elderly people with cognitive impairment, we do not yet know how it affects balance. The aim of our study was to determine the acceptability and effect of a 12-week horticultural therapy on balance and walking speed among institutionalized older adults with cognitive impairment. METHODS: This mixed-methods controlled trial included 23 participants. Subjects in the experimental group (n=13) participated in a 60â¯min horticultural therapy programme twice a week for 12 weeks in addition to the institution's usual social activities. Subjects in the control group (n=10) participated in the institution's usual social activities. Static and dynamic balance were measured with the Performance Oriented Mobility Assessment scale. In addition, gait speed was measured. Qualitative data were collected through a semi-structured interview with participants of the experimental group. RESULTS: At the end of the intervention period, the experimental maintained their baseline performance on the static balance, while the control group showed a decline. The gait speed of the experimental improved, while that of the control group did not change. In dynamic balance, no changes were demonstrated. The results of our qualitative data analysis indicate that horticultural therapy increases the possibility of social interactions, encourages older people to engage in conversation. CONCLUSIONS: As a conclusion, horticultural therapy should be more widely included in programmes for older people with cognitive impairment.
RESUMO
The creation of sustainable urban communities is contingent upon the establishment of a sustainable, efficient, and fast transportation system. Bicycle sharing systems (BSS) are one of the most sustainable and inclusive ways of transportation in cities. An important question is how to increase BSS ridership and whether it can effectively replace cars in cities, hence contributing to achieving the 11th Sustainable Development Goal and creating sustainable urban communities. This paper aims to contribute to this stream of research by investigating the effect of fuel prices on BSS ridership. We exploit a natural experiment from Budapest, Hungary, where fuel prices were capped between November 15, 2021, and December 6, 2022. Once the price cap was suddenly eliminated, fuel prices increased by around one-third immediately leading to a very substantial and rarely observable one-time price increase. The difference-in-difference regression results indicate a 2-6% increase in BSS ridership after the elimination of the fuel price cap. The geographical pattern of the change shows that BSS usage mainly increased in the outer part of the city; however, some areas observed a decline. The regression results are also reinforced by survey findings. Understanding these dynamics is crucial for effective urban planning and transportation policymaking.
RESUMO
PURPOSE: To translate the Berg Balance Scale (BBS) to Hungarian and to evaluate the psychometric characteristics of the Hungarian version (HU-BBS). METHODS: In total, 150 institutionalised older adults were recruited for the study. Eighty-one participants completed the retesting. Internal consistency, intra- and inter-rater reliability, and 95% limits of agreement of the HU-BBS were examined. Construct validity was assessed through convergent, discriminant, and known-group validity. RESULTS: The overall Cronbach's alpha was 0.943. The intra- and inter-rater reliability was excellent (intraclass correlation coefficient > 0.92). The Bland-Altman analysis revealed a mean inter-rater difference of 0.284 [-2.193-2.744] and a mean intra-rater difference of 0.259 [-2.657-3.162]. Regarding convergent validity, the HU-BBS was correlated with the functional status (r = 0.833), Timed Up and Go test (r= -0.824), and age (r= -0.606). The HU-BBS scores of women were similar to those of men (p = 0.104), showing discriminant validity. Additionally, the HU-BBS scores were lower among faller than among non-faller participants (p Ë 0.0001), establishing known-group validity. CONCLUSIONS: Translation and cultural adaptation of the original scale was successful. The HU-BBS proved to be a reliable, valid tool confirming that it can be used in future clinical and scientific work on Hungarian older adults.Implications for rehabilitationInstitutionalised older adults are vulnerable and at a high risk of developing further decline in postural control, contributing to an increase in limited functional mobility and risk for falls.The Berg Balance Scale is a widely used tool originally developed to measure postural control in older adults.The Hungarian version of the Berg Balance Scale tested on institutionalised older adults shows excellent test-retest reliability, good internal consistency, and acceptable convergent construct validity.The Hungarian version of the Berg Balance Scale is a valid and reliable tool for measuring postural control among Hungarian-speaking institutionalised older adults both in clinical practice and scientific studies.

BACKGROUND: Previous studies have suggested that macrophages are present during lens regeneration in newts, but their role in the process is yet to be elucidated. METHODS: Here we generated a transgenic reporter line using the newt, Pleurodeles waltl, that traces macrophages during lens regeneration. Furthermore, we assessed early changes in gene expression during lens regeneration using two newt species, Notophthalmus viridescens and Pleurodeles waltl. Finally, we used clodronate liposomes to deplete macrophages during lens regeneration in both species and tested the effect of a subsequent secondary injury after macrophage recovery. RESULTS: Macrophage depletion abrogated lens regeneration, induced the formation of scar-like tissue, led to inflammation, decreased iris pigment epithelial cell (iPEC) proliferation, and increased rates of apoptosis in the eye. Some of these phenotypes persisted throughout the last observation period of 100 days and could be attenuated by exogenous FGF2 administration. A distinct transcript profile encoding acute inflammatory effectors was established for the dorsal iris. Reinjury of the newt eye alleviated the effects of macrophage depletion, including the resolution of scar-like tissue, and re-initiated the regeneration process. CONCLUSIONS: Together, our findings highlight the importance of macrophages for facilitating a pro-regenerative environment in the newt eye by regulating fibrotic responses, modulating the overall inflammatory landscape, and maintaining the proper balance of early proliferation and late apoptosis of the iPECs.

The microenvironment influences cell fate. In this collection of voices, researchers from the fields of cancer and regeneration highlight approaches to establish the importance of the microenvironment and discuss future directions to understand the complex interaction between cells and their surrounding environment and how this impacts on disease and regeneration.
