In northeastern Brazil, the sugarcane expansion has occurred historically over the Atlantic Forest biome. However, little is known about the physical process and changes induced by sugarcane cultivation in this biome. Thus, a field study was conducted to evaluate changes induced by sugarcane cultivation on soil physical properties, processes and functions in the Atlantic Forest biome. For that, soil samples were collected at three sites in northeastern Brazil: AF – Atlantic Forest, SCratoon – successive sugarcane ratoon cultivation and SCtill – tilled soil for sugarcane replanting. Quantitative and semi-quantitative soil properties i.e. bulk density, soil penetration resistance (SPR), water-stable aggregates, soil organic carbon (C), pore size distribution and Visual Evaluation of Soil Structure (VESS) scores were examined. In addition, four critical soil functions were evaluated by a soil physical quality index (SPQI). Atlantic Forest soil presented the greatest soil physical quality (i.e. lower bulk density, higher porosity, soil C and soil aggregate stability), functioning, according to SPQI, at 88% of its full capacity. However, SPR under AF was significantly higher than SCratoon and SCtill. Soil tillage reduced SPR in SCtill compared to the area under successive sugarcane cultivation (SCratoon). The results revealed that the high SPR in AF and SCratoon areas occurred without soil volume variation (i.e. no compaction) in relation to the SCtill, indicating that these soils are susceptible to hardening induced by C bonds and thixotropy processes. Soil tillage for sugarcane replanting resulted in immediate improvements on physical conditions for root growth by decreasing SPR; however, soil disturbance increases its susceptibility to degradation by reducing water-stable soil aggregate, organic C and aeration pores. Thus, sugarcane cultivation declined the performance of soil physical functions to 72 and 67% of its full capacity in SCtill and SCratoon, respectively. Finally, best management practices to reduce soil disturbance and increase C should be prioritised, as well as minimising the mechanisms responsible by soil hardening in order to reduce soil physical degradation and improve the environment for root growth in sugarcane fields.
To examine studies involving the impact of telerehabilitation (TLR), tele-training and tele-support on the dyad stroke survivor and caregiver in relation to psychological, physical, social and health ...dimensions.
A systematic review was conducted.
The following electronic databases were consulted until September 2023: PsycInfo, CINAHL, Eric, Ovid, PubMed, Scopus, Cochrane Central and Web of Science.
It was conducted and reported following the checklists for Reviews of PRISMA 2020 Checklist. Critical evaluation of the quality of the studies included in the review was performed with the Joanna Briggs Institute Checklists.
A total of 2290 records were identified after removing duplicates, 501 articles were selected by title and abstract and only 21 met the inclusion criteria. It included 4 quasi-experimental studies, 7 RCTs, 1 cohort study and 9 qualitative studies. The total number of participants between caregivers and stroke survivors was 1697, including 858 stroke survivors and 839 caregivers recruited from 2002 to 2022. For a total of 884 participants who carried out TLR activities in the experimental groups,11 impact domains were identified: cognitive/functional, psychological, caregiver burden, social, general health and self-efficacy, family function, quality of life, healthcare utilization, preparedness, quality of care and relationship with technology.
The results support the application of telehealth in the discharge phase of hospitals and rehabilitation centres for stroke survivors and caregivers. TLR could be considered a substitute for traditional rehabilitation only if it is supported by a tele-learning programme for the caregiver and ongoing technical, computer and health support to satisfy the dyad's needs.
Designing a comprehensive telemedicine programme upon the return home of the dyad involved in the stroke improves the quality of life, functional, psychological, social, family status, self-efficacy, use of health systems and the dyad's preparation for managing the stroke.

The nutrient use efficiency in integrated crop-livestock systems under system fertilization may be related to soil structural variations caused by grazing. These hypothetical cause-effect ...relationships are not known, which reflects a limited understanding of the underlying processes. This study evaluated the association between soil structural quality and system fertilization efficiency of phosphorus and potassium in an integrated crop-livestock system and a pure crop system. The treatments were two fertilization strategies (system fertilization and crop fertilization) in a factorial scheme with two production systems (an integrated crop-livestock system and a pure crop system) distributed in a randomized block design with four replicates. In the pure crop system, soybean was grown followed by Italian ryegrass as a non-grazed cover crop. In the integrated crop-livestock system, the ryegrass was grazed by sheep. In the crop fertilization strategy, phosphorus and potassium were applied at the soybean planting, and nitrogen in the ryegrass establishment. In the system fertilization strategy, nitrogen, phosphorus, and potassium were applied during the establishment of ryegrass. Soil physical quality indices were calculated for the beginning, middle, and end of the pasture phase (2020) and at the soybean harvest (2021). Forage and soybean production were also evaluated. Based on the soil physical quality index, the soil’s ability to perform its physical functions decreased from 94% under an integrated crop-livestock system to 89% under a pure crop system. The results indicated higher total forage production (36%) and soybean yield (13%) in the system fertilization strategy as compared to the crop fertilization strategy. Moreover, the integrated crop-livestock system produced more forage (31%) and soybean grains (15%) than the pure crop system. The study provides the first evidence that higher structural quality of soils in an integrated crop-livestock system favors crop yields at all stages of production. However, the nutrient use efficiency in system fertilization is only partially explained by the soil’s physical quality.

Globally, the rate of land-use change (LUC) is increasing rapidly to support biofuel feedstock production. In Brazil, sugarcane (Saccharum officinarum) expansion to produce ethanol is displacing ...degraded pastures. Intensive mechanization for sugarcane production, could impact soil physical quality in these areas. We evaluated a typical LUC sequence (i.e., native vegetation–pasture–sugarcane) on soil physical quality at three sites in the central-southern region of Brazil. The soil physical properties evaluated through on-farm and laboratory soil analyses were: bulk density, degree of compactness, macroporosity, microporosity and total porosity, water-filled pore space, indexes of soil water storage and aeration capacity, soil resistance to penetration, field-saturated hydraulic conductivity and stability structural index. Calculations of mean weight diameter for the soil aggregates and soil physical quality ratings from a visual evaluation of soil structure (VESS) were also included in this study. From those data we defined a minimum dataset for calculating an additive soil physical quality index (SPQI). Long-term conversion from native ecosystems to pasture increased soil compaction (i.e., higher bulk density, degree of compactness and resistance to penetration values), decreased aeration porosity and water hydraulic conductivity, and consequently, created an unbalanced ratio between water- and air-filled pore space in the soil. Based on our SPQI, the soil's capacity to perform its physical functions decreased from 90% under native vegetation to 73% under pasture. Land-use change from pasture to sugarcane induced slight soil physical quality degradation, in which soil function was 68 and 56% of capacity. Overall, soil physical quality decreased under sugarcane fields, due to decreases in soil porosity, aeration and water hydraulic conductivity as well as increases in soil penetration resistance, structural degradation and erosion risk. Tillage operations performed during the sugarcane replanting (~5years) had a short-term positive effect on soil physical quality, although over time it further decreased the resistance to erosion and structural degradation. Therefore, to convert degraded pasture to sugarcane in a sustainable manner, the soils should be managed in ways that increase the soil organic matter and minimize compaction. These actions are needed to prevent further soil physical quality degradation and to improve both economic and environmental sustainability of sugarcane ethanol production.

To investigate the relationship between dietary diversity and healthy aging (in terms of mobility performance, physical functions, cognitive functions, and depressive symptoms) among ...community-dwelling middle-aged and older adults by using a nationally representative population-based cohort study.
Data from 3213 study participants in the Taiwan Longitudinal Study on Aging (TLSA) were retrieved for analysis, and all participants were divided into five groups according to the quintile of dietary variety scores (DVSs). In the 4-year follow-up study, multivariate logistic regression models were applied to investigate the associations between DVS subgroups and declines in mobility performance, physical function (activities of daily living (ADLs) and instrumental activities of daily living (IADLs)), cognitive function and depressive symptoms.
In this study, the DVS quintile identified people who were significantly vulnerable in diet quality. Among those in the lowest DVS quintile, the proportions consuming seafood, eggs, and beans/legumes per week were 0.3 %, 7.8 % and 12.6 %, respectively, while among those in the highest DVS quintile, the proportions were 40.2 %, 83.1 %, and 82.7 %, respectively. “Inverse” dose–response associations were observed between the DVS and the risks of decline in mobility performance, physical function (ADLs and IADLs), cognitive function, and depressive symptoms. These risks decreased with the higher DVS quintile group as compared to the lowest DVS quintile group. Even after adjustments for demographics, health behaviors (e.g., physical activity) and comorbidities, participants in the highest DVS quintile group were still associated with the lowest risk of decline in ADLs (adjusted odds ratio (aOR) 0.59 95 % confidence interval (CI) 0.37–0.94, p < 0.05) and IADLs (aOR 0.53 0.39–0.73, p < 0.01). However, no such association was observed in the risk of worsened mobility performance, cognitive function and depressive symptoms.
In conclusion, higher dietary diversity has protective effects in declines in multidimensional outcomes associated with healthy aging, particularly physical functions (ADL and IADL), among community-dwelling middle-aged and older adults. Intervention studies are needed to confirm the causal relationships between dietary diversity and healthy aging.
A systematic review and meta-analysis with narrative synthesis was conducted to evaluate the impact of dance exergaming on older adults' health-related outcomes and its feasibility, usability, and ...safety.
PubMed, Scopus, CINAHL, Web of Science, The Cochrane Library, ProQuest Dissertations and Theses Global, and Google Scholar were searched from inception to December 7, 2023. Interventional studies using immersive or nonimmersive virtual reality platforms conducted on older adults ≥60 years old were eligible. Meta-analysis was conducted using the random effects model by pooling mean differences (MD) or standardized mean differences. Outcomes were narratively synthesized when meta-analysis was not possible.
Forty-three articles from 37 studies were included (n = 1 139 participants at baseline). Postintervention, dynamic balance measured using Berg Balance Scale (pooled MD = 2.65, 95% CI: 1.73-3.57, p < .0001), Timed-Up-and-Go times (pooled MD = -1.04, 95% CI: -2.06 to -0.03, p = .04), choice stepping reaction time (pooled MD = -92.48, 95% CI: -167.30 to -17.67, p = .02), and movement time (pooled MD = -50.33, 95% CI: -83.34 to -17.33, p = .003) were significantly better in the experimental group compared to the control group. Adherence ranged from 76.5% to 100%, whereas attrition ranged from 9.1% to 31.9%. Most participants completed the intervention with no or minimal adverse effects.
Dance exergames are effective, feasible, usable, and safe for older adults. Further research is needed as the findings were limited by small sample sizes. Many studies could not be included in the meta-analysis as outcomes were too varied.
•Cognitive-motor dual-task training has positive effects on cognitive and physical functions.•Exergames have positive effects on cognitive functions.•Feasibility and optimal modalities of both ...interventions are yet unclear.•Safety, adherence, transfer and retention of benefits remains unexplored.
This overview aims to summarize the effectiveness of cognitive-motor dual-task and exergame interventions on cognitive, physical and dual-task functions in healthy older adults, as well as the feasibility, safety, adherence, transfer and retention of benefits of these interventions. We searched for systematic reviews or meta-analyses assessing the effects of cognitive-motor dual-task and exergame interventions on cognitive, physical and dual-task functions in cognitively healthy older adults through eight databases (CDSR (Cochrane), MEDLINE (PubMed), Scopus, EMBASE, CINAHL, PsycINFO, ProQuest and SportDiscus). Two reviewers performed the selection, data extraction and risk of bias evaluation independently (PROSPERO ID: CRD42019143185). Eighteen reviews were included in this overview. Overall, positive effects of cognitive-motor dual-task interventions on cognitive, physical and dual-task functions, as well as exergames on cognitive functions only, were observed in cognitively healthy older adults. In contrast, the effects of exergames on physical functions are more controversial, and their effects on dual-task functions have not been studied. The feasibility, safety, adherence, transfer and retention of benefits for both intervention types are still unclear. Future studies should follow more rigorous methodological standards in order to improve the quality of evidence and provide guidelines for the use of cognitive-motor dual-task and exergame interventions in older adults.

Background/Aims: There is no consensus regarding the optimal nonpharmacological intervention to slow down dementia-related decline. We examined whether physical stimulation interventions were ...effective in reducing cognitive, physical, mood, and behavioral decline in nursing home residents with dementia. Methods: Eighty-seven nursing home residents with dementia were randomly assigned to 3 physical activity interventions: activities of daily living (ADL) training, multicomponent exercise training, or combined multicomponent exercise and ADL training. Outcomes were measured at baseline, and after 3 and 6 months. Results: A 6-month ADL training benefitted executive functions, physical endurance, and depression among men. Exercise training benefitted only grip strength of participants with mild-to-moderate cognitive impairment. A combined training benefitted functional mobility compared to ADL training, depressive symptoms and agitation compared to exercise training, and physical endurance compared to no physical stimulation. Conclusions: ADL training appears to be effective for nursing home residents with moderately severe dementia. It remains unclear whether exercise training is an effective type of stimulation.
•We have added another purpose of the current study in the introduction section according to your suggestion.•We added the total number of physical test data for analysis and new table which showed ...the cumulative number of participant and physical test registry data to make it clearly understand.•We added sentences about the data quality for fall in the limitation section.•Following the reviewer's suggestion, we revised the Table 3 including falls and FOF for analysis.
Exercises that target muscle strength, balance, and gait prevent falls in older people. Moreover, exercise may reduce fear of falling by improving physical function. Many studies have examined the risk factors for falls and fear of falling separately. However, few studies have examined the associations between physical function, falls, and fear of falling simultaneously. This study aimed to identify the key physical functions influencing falls and fear of falling.
Longitudinal observational study
This study included 2,397 older adults (women: 82.8%, mean age: 74.3 ± 8.0 years) who participated in community-based physical exercise.
Physical functions such as muscle strength, balance, gait speed, and flexibility were measured regularly during the program. A questionnaire regarding falls and fear of falling was also administered simultaneously. Multilevel modeling was used to investigate the association between physical function and falls and fear of falling.
The prevalence of falls and fear of falling at enrolment were 27.1% and 49.8%, respectively. Statistical analyses revealed that (1) falls were significantly associated with balance, age, fall history, fear of falling, and duration of participation; (2) fear of falling was significantly associated with muscle strength, balance, gait speed, age, and fall history. Long-term participation was significantly associated with an improvement in balance.
The risk factors for falls and fear of falling were different. Our research showed the importance of including balance training in all prevention programs.
