- The PREDICTS project-Projecting Responses of Ecological Diversity In Changing Terrestrial Systems (www.predicts.org.uk)-has collated from published studies a large, reasonably representative database of comparable samples of biodiversity from multiple sites that differ in the nature or intensity of human impacts relating to land use. We have used this evidence base to develop global and regional statistical models of how local biodiversity responds to these measures. We describe and make freely available this 2016 release of the database, containing more than 3.2 million records sampled at over 26,000 locations and representing over 47,000 species. We outline how the database can help in answering a range of questions in ecology and conservation biology. To our knowledge, this is the largest and most geographically and taxonomically representative database of spatial comparisons of biodiversity that has been collated to date; it will be useful to researchers and international efforts wishing to model and understand the global status of biodiversity.

- Background: Parkinson's disease (PD) is characterized by motor deficits and brain alterations having a detrimental impact on balance, gait, and cognition. Intensive physical exercise can induce changes in the neural system, potentially counteracting neurodegeneration in PD and improving clinical symptoms. Objective: This randomized controlled trial investigated effects of a highly challenging, cognitively demanding, balance and gait training (HiBalance) program in participants with PD on brain structure. Methods: 95 participants were assigned to either the HiBalance or an active control speech training program. The group-based interventions were performed in 1-hour sessions, twice per week over a 10-week period. Participants underwent balance, gait, cognitive function, and structural magnetic resonance imaging assessments before and after the interventions. Voxel-based morphometry was analyzed in 34 HiBalance and 31 active controls. Additionally, structural covariance networks were assessed. Results: There was no significant time by group interaction between the HiBalance and control training in balance, gait, or brain volume. Within-HiBalance-group analyses showed higher left putamen volumes post-training. In repeated measures correlation a positive linear, non-significant relationship between gait speed and putamen volume was revealed. In the HiBalance group we found community structure changes and stronger thalamic-cerebellar connectivity in structural covariance networks. Neither brain volume changes nor topology changes were found for the active controls after the training. Conclusion: Thus, subtle structural brain changes occur after balance and gait training. Future studies need to determine whether training modifications or other assessment methods lead to stronger effects.

- OBJECTIVE: To describe health issues and living conditions in a cohort of adults living with Spina bifida.MATERIAL AND METHODS: A cross-sectional study was conducted by a multidisciplinary team. Adults with spina bifida (n = 219) were invited to participate. One-hundred-and-ninety-six persons (104 women and 92 men; 18-73 years, median age 33 years) were included. Structured interviews, questionnaires, and clinical assessments for medical, social, physical, and cognitive functions were used.RESULTS: There was large variation among participants as regards the consequences of their spina bifida. Individuals < 46 years seemed to have more secondary conditions such as hydrocephalus, Chiari II malformation, tethered cord symptoms, and latex allergy. A higher proportion of the individuals >46 years and older was able to walk, and they had performed better in primary school and on tests of psychomotor speed and executive function.CONCLUSIONS: This study demonstrates that adults with spina bifida have a complex set of physical, cognitive, and social needs that need to be addressed in order to improve their health issues and living conditions. The high prevalence of urinary and fecal incontinence, pain, and overweight underline that these issues need much attention during follow-up. The future generations of older adults may need more attention in many ways, since they at a younger age do have more complex medical conditions, lower physical and cognitive functions, and lower prerequisites for independent living and participation in society than those > 46 years today. This elucidates that adults with spina bifida need systematic follow-up services and social support throughout life.

- STUDY DESIGN: Cross-sectional study.OBJECTIVE: Describe and compare ambulatory performance and cognitive capacity in relation to muscle function in an adult cohort with spina bifida. Also, explore factors associated with ambulation in participants with muscle function level 3.SETTING: Specialist clinic for adults with spinal cord disorders in Stockholm, Sweden.METHODS: A total regional cohort of adults (n = 219) with spina bifida was invited, 196 (104 women, mean age 35 years, SD 13 years) participated. Mode of mobility, cognitive capacity and muscle function were investigated. For participants with muscle function level 3, factors associated with ambulation were investigated using multivariate logistic regression analysis.RESULTS: In all, 84 participants (42%) were community ambulators, 22 (12%) household ambulators and 90 (46%) wheelchair users. There was a linear association between the lower degree of muscle function and scoliosis (P < 0.001). Mode of mobility varied despite similar muscle prerequisites in participants with muscle function level 3 (n = 58). Factors associated with ambulation in participants with muscle function level 3 were the absence of scoliosis, lower BMI and higher cognitive capacity.CONCLUSIONS: Cognitive capacity and mode of mobility varied widely across the cohort. However, in participants with muscle function level 3, despite similar muscular prerequisites, a large variation in the mode of mobility was found, suggesting that other factors were involved. It is important to prevent scoliosis, support a healthy lifestyle, as well as offer cognitive screening and support to promote ambulatory function and optimise independence in the everyday lives of adults with spina bifida.

- BACKGROUND: Spina bifida (SB) is a complex congenital malformation, often causing impaired gait performance depending on the level and extent of malformation. Research regarding gait and balance performance in adults with SB, has not been sufficiently described yet.RESEARCH QUESTION: What are the characteristics of spatiotemporal gait parameters and balance performance in adults with SB? Further, do persons with muscle function (MF) level 3 differ regarding gait and balance performance from those with MF level 1-2?METHODS: Cross-sectional observational study at an outpatient clinic. 41 adults with SB (18-65 years), who walked regularly. Spatiotemporal parameters of gait was assessed with the APDM system and balance performance with the Mini Balance Evaluation Systems Test (Mini-BESTest). Muscle strength in the legs was assessed with 0-5 manual muscle test, and participants were classified according to level of MF into groups MF1, MF2, and MF3. Two-sided t-test was used for parametric independent variables, and Cohen's d was used for effect sizes. The Mann-Whitney U test was used for non-parametric independent data and effect size was calculated by the z value (r = z/√n).RESULTS: Mean gait speed was 0.96 (SD 0.20) m/s and mean stride length 1.08 m (SD 0.17), individuals with MF3 showed significantly slower gaitspeed and shorter stride length (p < 0.05). Lumbar rotation was 21° (SD 11), and thoracic lateral sway 15° (IQR 15) with significantley difference (p < 0.001 and p < 0.05) for individuals in MF3. Mini-BESTest showed a mean score of 11.3 (SD 6.9), and individuals with MF3 showed significantly lower scores (p ≤ 0.001).SIGNIFICANCE: Gait and balance performance was reduced compared to normative data in almost all parameters, especially in persons with less muscle function. Increased knowledge from advanced gait analysis may help healthcare professionals to design rehabilitation programmes, in order to achieve and maintain a sustainable gait and balance performance.

Konferensbidrag (refereegranskat)abstract
- Introduction Seventy-five per-cents of children born with Spina Bifida (SB) are expected to live into adulthood, meaning that the adults will need more attention in the future. Adulthood involves great demands for persons with SB, but also for their families, the social well-fare and healthcare systems, as the group has a persistent need for care and support. The aim is to describe the living and health conditions for adults with Spina Bifida in different life stages including medical, physical, psychological, cognitive and social aspects. Methods A cross-sectional study conducted by a multidisciplinary team. Data collection was performed through structured interviews, questionnaires and clinical assessments. All individuals > 18 years with SB (n=219) registered at a regional outpatient clinic were offered participation; 196 persons (104 women, 92 men 18-73 years) were included. Results There was a great variation in the group concerning problems related to their congenital injury. The persons > 45 years and especially > 61 years seems to have less problems such as less prevalence of hydrocephalus, Chiari II malformation, tethered cord syndrome and they also walked to a higher extent. They passed elementary school to a higher extent and performed better on the tests for psychomotor speed and executive function. Conclusions The study shows the multifaceted problems this group is facing as adults with SB and contributes to increased knowledge concerning the living and health conditions. Increased knowledge can lead to targeted interventions and better care, thereby decreasing secondary complications, reducing costs for society and hopefully increasing quality of life for persons with SB and their families.

- BackgroundThe knowledge about striatal hand deformities (SHD) in Parkinson’s disease (PD), has recently increased but need more attention due to their early impact on dexterity. The focus of clinical studies has been on the staging of SHD severity and neurological features. However, a hand surgical perspective has not been considered.ObjectivesOur purpose was to examine SHD in patients with PD using hand surgical assessmentmethods and the recommended staging of SHD.MethodsIn this observational study, a specialist in neurological physiotherapy examined 100 consecutive PD patients and identified 35 with suspected SHD, who were thenexamined by two hand surgeons. Their hands were clinically evaluated for severity of SHD, according to a previous proposed staging, focusing on metacarpophalangeal (MCP) joint flexion, presence of intrinsic and extrinsic tightness, as well as other hand deformities.ResultsThree kinds of deformities were identified among 35 included patients: surgicaldiagnoses unrelated to PD (n=5), SHD (n=23), and PD related hand deformities with increased extrinsic tightness (n=10); three of these 10 patients had also contralateral SHD, thus are included in SHD group. In addition to previously described MCP joint flexion, swan neck deformity and z-thumb deformity, we found in most hands finger “clefting”, abduction of the little finger and/or an increased intrinsic tightness, indicating pathology of intrinsic muscles of the hand involved in SHD.ConclusionsSHD diagnosed with a modified staging method, including features of intrinsic andextrinsic hand deformities, should be considered in PD to implement early and more accurate treatment

- Objectives: The aim of this study was to create a screening tool to predict first-time injurious falls in community-living older men and women. Design: Longitudinal cohort study between 2001 and 2009. Setting: The Swedish National Study on Aging and Care in Kungsholmen (SNAC-K), Sweden. Participants: Community-living older adults (n = 2808; 1750 women and 1058 men) aged >= 60 years (mean age 73, standard deviation 10.3). Measurements: The outcome was injurious falls within 5 years from baseline survey. Data on the risk factors for falls were collected through interviews, clinical examinations, and tests at baseline. Several previously established fall risk factors were identified for the development of the screening tool. The tool was formulated based on the beta coefficients from sex-specific multivariate Cox proportional hazards models. The discriminative power was assessed using Harrell C statistic. Results: Old age, living alone, being dependent in instrumental activities of daily living, and impaired balance were the factors included in the final score of the First Injurious Fall (FIF) screening tool. The predictive values (Harrell C statistic) for the scores were 0.75 for women and 0.77 for men. The sensitivity and specificity at the Youden cut-off points were 0.69 and 0.70 for women, and 0.72 and 0.71 for men. Conclusions and Implications: The FIF screening tool for first injurious fall in older persons consists of 3 questions and a physical test (5-second 1-leg standing balance with eyes open). Quick and easy to administer, it could be ideal for use in primary care or public health to identify older men and women at high fall risk, who may benefit from primary preventive interventions.
