An overview of the progress and challenges of peatland restoration in Western Europe

Abstract: Peatlands are the most efficient terrestrial carbon store on Earth, and deliver multiple other ecosystem services including climate regulation, water purification, preservation of ecological and archaeological records, etc. Disturbed and degraded peatlands do not provide the same ecological services and thus bear a significant cost to society. Because this cost may be alleviated by appropriate restoration measures, money is being invested in peatland restoration projects around the world. Here, we review over 25 years of restoration in Western Europe. First, we provide an overview of techniques used in different contexts and evaluate the status of the evidence base for restoration outcomes. Between 1993 and 2015, the EU-LIFE nature programme alone invested 167.6M € in 80 projects, which aim to restore over 913 km2 of peatland habitats in Western European countries, mostly in protected sites part of the Natura 2000 EU network. This represents less than 2% of the total remaining area of peatlands in these countries, most of which have been impacted to some degree by anthropogenic disturbances. Potential for restoration should be considered in nondesignated sites. We reviewed a number of case studies covering a range of restoration approaches used in different parts of Western Europe. We found that published evidence of restoration progress was limited to specific sites/areas, and in many cases lacked baseline measurements and clear goals, that is, measurable target or contemporary reference(s). We discuss barriers and opportunities to turn the tide for peatland restoration in Western Europe and promote the establishment of robust, standardized monitoring schemes.

Child and adolescent mental health amidst emergencies and disasters.

Abstract: The mental health of children and young people can be disproportionally affected and easily overlooked in the context of emergencies and disasters. Child and adolescent mental health services can contribute greatly to emergency preparedness, resilience and response and, ultimately, mitigate harmful effects on the most vulnerable members of society.

Speech and language therapy to improve the communication skills of children with cerebral palsy.

Abstract: Background: The production of speech, language and gesture for communication is often affected by cerebral palsy. Communication difficulties associated with cerebral palsy can be multifactorial, arising from motor, intellectual and / or sensory impairments, and children with this diagnosis can experience mild to severe difficulties in expressing themselves. They are often referred to speech and language therapy (SLT) services, to maximise their communication skills and help them to take an independent a role as possible in interaction. This can include introducing augmentative and alternative communication (AAC) systems, such as symbol charts or speech synthesizers, as well treating children's natural forms of communication. Various strategies have been used to treat the communication disorders associated with cerebral palsy but evidence of their effectiveness is limited. Objectives: • To determine the effectiveness of SLT that focuses on the child or their familiar communication partners, as measured by change in interaction patterns. • To determine if individual types of SLT intervention are more effective than others in changing interaction patterns. Search strategy: Searches were conducted of MEDLINE, CINAHL, EMBASE, PSYCH INFO, LLBA, ERIC, WEB of SCIENCE, NRR, BEI, SIGLE up to December 2002. References from identified studies were examined and relevant journals and conference reports were hand-searched. Selection criteria: Any experimental study containing an element of control was included in this review. This includes non-randomised group studies and single case experimental designs in which two interventions were compared or two communication processes were examined. Data collection and analysis: L Pennington searched for and selected studies for inclusion. J Goldbart and J Marshall independently assessed separate random samples each comprising 25% of all identified studies. Two reviewers independently abstracted data from each selected study. Disagreements were settled by discussion between the three reviewers. Main results: Eleven studies were included in the review. Seven studies evaluated treatment given directly to children, four investigated the effects of training for communication partners. Subjects in the studies varied widely in age, type and severity of cerebral palsy, cognitive and linguistic skills. Studies focusing directly on children suggest that this model of therapy delivery has been associated with increases in treated communication skills by individual children. However, methodological flaws prevent firm conclusions being made about the effectiveness of therapy. In addition, maintenance of these skills was not investigated thoroughly. The studies targeting communication partners describe small exploratory group projects which contain insufficient detail to allow replication, have very low power and cannot provide evidence of effectiveness of this type of treatment. Authors' conclusions: Firm evidence of the positive effects of SLT for children with cerebral palsy has not been demonstrated by this review. However, positive trends in communication change were shown. No change in practice is recommended from this review. Further research is needed to describe this client group, and its possible clinical subgroups, and the methods of treatment currently used in SLT. Research is also needed to investigate the effectiveness of new and established interventions and their acceptability to families. Rigour in research practice needs to be extended to enable firm associations between therapy and communication change to be made.

In vivo cholinergic basal forebrain atrophy predicts cognitive decline in de novo Parkinson's disease.

Abstract: See Gratwicke and Foltynie (doi:10.1093/brain/awx333) for a scientific commentary on this article.Cognitive impairments are a prevalent and disabling non-motor complication of Parkinson's disease, but with variable expression and progression. The onset of serious cognitive decline occurs alongside substantial cholinergic denervation, but imprecision of previously available techniques for in vivo measurement of cholinergic degeneration limit their use as predictive cognitive biomarkers. However, recent developments in stereotactic mapping of the cholinergic basal forebrain have been found useful for predicting cognitive decline in prodromal stages of Alzheimer's disease. These methods have not yet been applied to longitudinal Parkinson's disease data. In a large sample of people with de novo Parkinson's disease (n = 168), retrieved from the Parkinson's Progressive Markers Initiative database, we measured cholinergic basal forebrain volumes, using morphometric analysis of T1-weighted images in combination with a detailed stereotactic atlas of the cholinergic basal forebrain nuclei. Using a binary classification procedure, we defined patients with reduced basal forebrain volumes (relative to age) at baseline, based on volumes measured in a normative sample (n = 76). Additionally, relationships between the basal forebrain volumes at baseline, risk of later cognitive decline, and scores on up to 5 years of annual cognitive assessments were assessed with regression, survival analysis and linear mixed modelling. In patients, smaller volumes in a region corresponding to the nucleus basalis of Meynert were associated with greater change in global cognitive, but not motor scores after 2 years. Using the binary classification procedure, patients classified as having smaller than expected volumes of the nucleus basalis of Meynert had ∼3.5-fold greater risk of being categorized as mildly cognitively impaired over a period of up to 5 years of follow-up (hazard ratio = 3.51). Finally, linear mixed modelling analysis of domain-specific cognitive scores revealed that patients classified as having smaller than expected nucleus basalis volumes showed more severe and rapid decline over up to 5 years on tests of memory and semantic fluency, but not on tests of executive function. Thus, we provide the first evidence that volumetric measurement of the nucleus basalis of Meynert can predict early cognitive decline. Our methods therefore provide the opportunity for multiple-modality biomarker models to include a cholinergic biomarker, which is currently lacking for the prediction of cognitive deterioration in Parkinson's disease. Additionally, finding dissociated relationships between nucleus basalis status and domain-specific cognitive decline has implications for understanding the neural basis of heterogeneity of Parkinson's disease-related cognitive decline.
