Abstract: Forests that regrow naturally on abandoned fields are important for restoring bio ersity and ecosystem services, but can they also preserve the distinct regional tree floras? Using the floristic composition of 1215 early successional forests (≤20 years) in 75 human-modified landscapes across the Neotropic realm, we identified 14 distinct floristic groups, with a between-group dissimilarity of 0.97. Floristic groups were associated with location, bioregions, soil pH, temperature seasonality, and water availability. Hence, there is large continental-scale variation in the species composition of early successional forests, which is mainly associated with biogeographic and environmental factors but not with human disturbance indicators. This floristic distinctiveness is partially driven by regionally restricted species belonging to widespread genera. Early secondary forests contribute therefore to restoring and conserving the distinctiveness of bioregions across the Neotropical realm, and forest restoration initiatives should use local species to assure that these distinct floras are maintained.

Abstract: Although deforestation is r ant across the tropics, forest has a strong capacity to regrow on abandoned lands. These “secondary” forests may increasingly play important roles in bio ersity conservation, climate change mitigation, and landscape restoration. Poorter et al . analyzed the patterns of recovery in forest attributes (related to soil, plant functioning, structure, and ersity) in 77 secondary forest sites in the Americas and West Africa. They found that different attributes recovered at different rates, with soil recovering in less than a decade and species ersity and biomass recovering in little more than a century. The authors discuss how these findings can be applied in efforts to promote forest restoration. —AMS

Abstract: Total Knee Arthroplasty (TKA) reduces pain and improves function in those suffering from severe osteoarthritis. A significant cost of TKA is post-acute care, however, current evidence suggests that discharge to an Inpatient Rehabilitation Facility (IRF) has inferior outcomes to home discharge, with no greater benefit in physical function. Only in idual studies have investigated TKA patient characteristics predictive of discharge destination, therefore, the aim is to systematically review the literature and meta-analyse intrinsic patient factors predictive of IRF discharge. If predictive factors are known, then early discharge planning and intervention strategies could be implemented. Databases PubMed, CINAHL, Embase, Cochrane, and Pedro were searched up to October 2019 for all studies investigating pre-operative intrinsic patient factors predictive of IRF discharge. For assessing the methodological quality of included studies, the Quality In Prognosis Studies (QUIPS) tool was used. Statistical analysis and graphical reporting were conducted in R statistical software. To assess the effect of predictors of discharge destination, odds ratios with the corresponding 95%CI were extracted from the results of univariate and multivariable analyses. A total of 9 articles published between 2011 to 2018 with 218,151 TKA patients were included. Of the 13 intrinsic patient factors reported, 6 met the criteria for synthesised review: age, obesity, comorbidity, gender, SF-12/VR-12 survey, and smoking. Due to the heterogeneity of statistical analysis and reporting 2 variables could undergo meta-analysis, gender and smoking. Female gender increased the likelihood of IRF discharge by 78% (OR = 1.78 95%CI = 1.43–2.20 I2 = 33.3%), however, the relationship between smoking status and discharge destination was less certain (OR = 0.80 95%CI = 0.42–1.50 I2 = 68.5%). In this systematic literature review and meta-analysis female gender was shown to be predictive of IRF discharge after total knee arthroplasty. There was also a trend for those of older age and increased comorbidity, as measured by the Charlson Comorbidity Index, or the severely obese to have an increased likelihood of IRF discharge. The marked heterogeneity of statistical methods and reporting in existing literature made pooled analysis challenging for intrinsic patient factors predictive of IRF discharge after TKA. Further, high quality studies of prospective design on predictive factors are warranted, to enable early discharge planning and optimise resource allocation on post-acute care following TKA.

Abstract: Abandonment of agricultural lands promotes the global expansion of secondary forests, which are critical for preserving bio ersity and ecosystem functions and services. Such roles largely depend, however, on two essential successional attributes, trajectory and recovery rate, which are expected to depend on landscape-scale forest cover in nonlinear ways. Using a multi-scale approach and a large vegetation dataset (843 plots, 3511 tree species) from 22 secondary forest chronosequences distributed across the Neotropics, we show that successional trajectories of woody plant species richness, stem density and basal area are less predictable in landscapes (4 km radius) with intermediate (40–60%) forest cover than in landscapes with high (greater than 60%) forest cover. This supports theory suggesting that high spatial and environmental heterogeneity in intermediately deforested landscapes can increase the variation of key ecological factors for forest recovery (e.g. seed dispersal and seedling recruitment), increasing the uncertainty of successional trajectories. Regarding the recovery rate, only species richness is positively related to forest cover in relatively small (1 km radius) landscapes. These findings highlight the importance of using a spatially explicit landscape approach in restoration initiatives and suggest that these initiatives can be more effective in more forested landscapes, especially if implemented across spatial extents of 1–4 km radius.

Abstract: Despite the routine use of physical therapy in the immediate and early postoperative phase for patients who undergo total knee replacement (TKR), there is a paucity of research into the optimal exercise protocols in both the acute inpatient setting and early period after discharge. Pedaling has often been recommended by clinicians after TKR for rehabilitation, but to our knowledge, there has been no investigation into its utility in the acute postoperative setting. Therefore, we performed a randomized controlled trial evaluating the efficacy of pedaling in the acute postoperative period. Sixty TKR patients were randomized to receive postoperative physical therapy involving either a 3-exercise pedaling (pedaling-based) or 10-exercise, non-pedaling (multi-exercise) protocol. Outcomes were assessed at 2 days, 2 weeks, and 4 months, and included physical tests of function, patient-reported outcomes, and other perioperative measures. With respect to the primary outcome, the 6-minute walk test (6MWT), the measured distance was significantly greater in the pedaling-based group than in the multi-exercise group at 2 days postoperatively (mean difference, 66 m p = 0.001). Results of other functional tests, the 10-m walk test (10MWT) and the Timed Up & Go (TUG) test, were both significantly superior for the 3-exercise pedaling group at 2 days (p = 0.016 for 10MWT, and p = 0.020 for TUG), as was the patient-reported Oxford Knee Score (p = 0.034). The latter continued to be superior at 2 weeks (p = 0.007), as was the EQ-5D score (p = 0.037). The visual analogue scale (VAS) component of the EQ-5D was significantly better for the pedaling group at all time points assessed. Length of stay was also significantly shorter, by a half-day, for the pedaling-based group (median of 2.5 days compared with 3.0 days for the multi-exercise group p = 0.024). The multi-exercise protocol was not superior for any outcome measure at any time point. A pedaling-based protocol in the immediate postoperative period after TKR was superior to a standard multi-exercise protocol in both functional and patient-reported outcomes, with these benefits decreasing over time.

Abstract: Tropical forests disappear rapidly through deforestation but also have the potential to regrow naturally through a process called secondary succession. To advance successional theory, it is essential to understand how these secondary forests and their assembly vary across broad spatial scales. We do so by synthesizing continental-scale patterns in succession using a functional trait approach. We show that the start and pathway of succession varies with climatic water availability. In dry forests, succession is driven by drought tolerance traits and in wet forests by shade tolerance traits. Based on these successional principles, we propose an ecologically sound strategy to improve active forest restoration.
