Monitoring the Penobscot River Restoration Project: Baseline Data to Inform Ecosystem Response

Dam removal is increasingly being used as a tool to restore aquatic habitats and recover imperiled species. However, many presumed effects of dam removal (i.e. fish community changes, water quality improvements) are largely un-documented. Given significant investments being made in dam removal, rigorous monitoring is needed to elucidate ecological impacts and allow for informed decision making when allocating restoration resources. The Penobscot River Restoration Project in Maine, USA, is an innovative restoration project aimed at restoring self-sustaining populations of diadromous fish through increased connectivity via dam removals and fish passage improvements, while maintaining hydropower output. Beginning prior to dam removal in 2009, independent researchers began documenting baseline conditions via a multi-disciplinary, coordinated monitoring framework. The framework has continued through project implementation, following a before-after study design. Monitoring focuses on geomorphology, water quality, fish community, fish passage, habitat use, shoreline revegetation and marine-freshwater nutrient transfers. As before-after comparative analyses continue to unfold, this presentation aims to provide the most current results of this monitoring effort, highlighting several patterns which have emerged to-date: 1) all native diadromous species of fish are present in the river, many successfully reproducing on their own; 2) diadromous species persist despite access to only a small percentage of their historic habitat, many now beginning to increase in number; 3) the former lowermost dam, represented a near complete barrier to migration for most species and is now traversed by many similarly to free-flowing sections; 4) large changes to flow, sediment regime, and habitat (except in the immediate vicinity of the former dam sites) were unexpected and did not occur; and 5) water quality did not appear to be limiting for most species. This effort provides an objective, credible basis for evaluating ecosystem response to dam removal and a knowledge base to support restoration approaches in other systems

Identifying individuals with intellectual disability who access mental health support and are at high risk for adverse clinical outcomes: cohort study

BACKGROUND: People with intellectual disability often experience aggressive challenging behaviour and mental health issues. It can be difficult to identify those who are at higher risk of adverse clinical outcomes when in clinical care. AIMS: To characterise potential subgroups in adults with intellectual disability referred to mental health services in those presenting with aggressive behaviour or common mental disorders (CMDs). METHOD: There were 836 adults (≥18 years) with intellectual disability and a record of aggressive challenging behaviour, and 205 patients with intellectual disability and CMDs, who were seen in specialist mental health services over a 5-year period. Cluster analysis was used to define patient characteristics associated with clinical outcome. RESULTS: Distinct patient groups with differentiated profiles were observed in people with intellectual disability displaying aggressive challenging behaviour, and in those presenting with CMDs. Characteristics of the aggressive behaviour group who experienced adverse outcomes included being <30 years old, being male, more mentions of aggression and agitation in their clinical record, a diagnosis of pervasive developmental disorder and prescription of psychotropic medication. Characteristics of the CMD cluster that experienced adverse clinical outcomes were being older, being a White male, having a mild intellectual disability and physical health concerns. CONCLUSIONS: People with intellectual disability who experience adverse clinical outcomes can be identified with a cluster analysis approach of common features, but differ by clinical presentation. This could be used not only to stratify this clinically heterogeneous population in terms of response to interventions, but also improve precision in the development of tailored interventions

Recording of intellectual disability in general hospitals in England 2006-2019: Cohort study using linked datasets

BACKGROUND: Accurate recognition and recording of intellectual disability in those who are admitted to general hospitals is necessary for making reasonable adjustments, ensuring equitable access, and monitoring quality of care. In this study, we determined the rate of recording of intellectual disability in those with the condition who were admitted to hospital and factors associated with the condition being unrecorded. METHODS AND FINDINGS: Retrospective cohort study using 2 linked datasets of routinely collected clinical data in England. We identified adults with diagnosed intellectual disability in a large secondary mental healthcare database and used general hospital records to investigate recording of intellectual disability when people were admitted to general hospitals between 2006 and 2019. Trends over time and factors associated with intellectual disability being unrecorded were investigated. We obtained data on 2,477 adults with intellectual disability who were admitted to a general hospital in England at least once during the study period (total number of admissions = 27,314; median number of admissions = 5). People with intellectual disability were accurately recorded as having the condition during 2.9% (95% CI 2.7% to 3.1%) of their admissions. Broadening the criteria to include a nonspecific code of learning difficulty increased recording to 27.7% (95% CI 27.2% to 28.3%) of all admissions. In analyses adjusted for age, sex, ethnicity, and socioeconomic deprivation, having a mild intellectual disability and being married were associated with increased odds of the intellectual disability being unrecorded in hospital records. We had no measure of quality of hospital care received and could not relate this to the presence or absence of a record of intellectual disability in the patient record. CONCLUSIONS: Recognition and recording of intellectual disability in adults admitted to English general hospitals needs to be improved. Staff awareness training, screening at the point of admission, and data sharing between health and social care services could improve care for people with intellectual disability

Aggressive challenging behaviour in adults with intellectual disability: an electronic register-based cohort study of clinical outcome and service use

Background: Aggressive challenging behavior in people with intellectual disability is a frequent reason for referral to secondary care services and is associated with direct harm, social exclusion, and criminal sanctions. Understanding the factors underlying aggressive challenging behavior and predictors of adverse clinical outcome is important in providing services and developing effective interventions. Methods: This was a retrospective total-population cohort study using electronic records linked with Hospital Episode Statistics data. Participants were adults with intellectual disability accessing secondary services at a large mental healthcare provider in London, United Kingdom, between 2014 and 2018. An adverse outcome was defined as at least one of the following: admission to a mental health hospital, Mental Health Act assessment, contact with a psychiatric crisis team or attendance at an emergency department. Results: There were 1,515 patient episodes related to 1,225 individuals, of which 1,019 episodes were reported as displaying aggressive challenging behavior. Increased episode length, being younger, psychotropic medication use, pervasive developmental disorder (PDD), more mentions of mood instability, agitation, and irritability, more contact with mental health professionals, and more mentions of social and/or home care package in-episode were all associated with increased odds of medium-high levels of aggression. Risk factors for an adverse clinical outcome in those who exhibited aggression included increased episode length, personality disorder, common mental disorder (CMD), more mentions of agitation in-episode, and contact with mental health professionals. PDD predicted better outcome. Conclusions: Routinely collected data confirm aggressive challenging behavior as a common concern in adults with intellectual disability who are referred for specialist support and highlight factors likely to signal an adverse outcome. Treatment targets may include optimizing management of CMDs and agitation

Identification of the invasive form of Corbicula clams in Ireland

The basket clam genus, Corbicula, commonly known as the Asian clam, has become one of the most internationally high-profile and widespread aquatic invasive species. This genus is now considered to comprise a polymorphic species complex. The international invasion of Corbicula is characterised by four lineages, each fixed for one morphotype, genotype and haplotype combination: the American form (A) and European round form (R), the American form (C) and European saddle from (S), American form B, form round light colour (Rlc) and an intermediate between forms R and S known as Int. We investigated the genetic and morphometric makeup of each Irish population in order to establish which invasive lineages were present so as to identify the number of introductions to Ireland. A combination of morphometric, mitochondrial cytochrome oxidase subunit I (mtCOI) gene analysis and microsatellite markers were used to determine the invasive form at each Irish site. All Irish Corbicula samples conformed morphometrically to the invasive form A/R. All mtCOI sequences retrieved for 25 Irish individuals were identical to the international A/R form, while microsatellite markers again showed a common clustering with the international A/R forms of Corbicula. The combined approach of morphometries, total genomic DNA and microsatellite markers indicate only one form of Corbicula invaded Ireland; the international A/R form

Learning from Lives and Deaths - People with a learning disability and autistic people (LeDeR) report for 2022

The seventh annual report of 'Learning from lives and deaths - People with a learning disability and autistic people' (LeDeR) focuses on reviews of deaths of people with a learning disability and autistic people that occurred in 2022. Comparison data from reviews of deaths in 2018 to 2021 is used to identify trends over time. Introduced by a foreword from the 'Staying Alive and Well' group, the report explores the demographics of people who died, circumstances and causes of death, factors associated with age at death, issues in quality of care and avoidable and excess deaths. Deaths of autistic people without a learning disability are included in the report for the first time in an important step towards understanding the unique challenges faced by autistic people

ARES(2014)2425342 - 22/07/2014. Organisation and running of a scientific workshop to complete selected invasive alien species (IAS) risk assessments

The introduction and spread of invasive alien species (IAS) constitutes one of the most important drivers of global change in biodiversity and ecosystem services. Robust risk assessment methods are required for IAS to provide the foundation upon which to prioritise appropriate action. In a previous study (Roy, Schonrogge et al. 2014) minimum standards were developed to provide an assessment framework for risk assessments and ultimately for underpinning the development of a proposed list of “IAS of EU concern”, in accordance to the provisions of the Regulation (EU) No 1143/2014 of the European Parliament and of the Council of 22 October 2014 on the prevention and management of the introduction and spread of invasive alien species. In practice, of the protocols assessed in detail, only four (GB NNRA, EPPO DSS, Harmonia+ and ENSARS) were sufficiently compliant with the minimum standards to be considered and of these only the GB NNRA and EPPO DSS have published IAS risk assessments. As a result, using the information from such “substantially compliant” protocols, a draft list of approximately 50 species was compiled. It is important to note that this list of species is based on availability of robust risk assessments already completed through methods which are almost compliant with the minimum standards, and it does not constitute the list of “IAS of EU concern”. In view of the application of the forthcoming EU Regulation on IAS (and building-on ENV.B.2/ETU/2013/0026) the Commission hosted a 2-day scientific workshop to examine the selected risk assessments and pool the existing knowledge existing in the EU to complete the missing information, on the basis of robust scientific evidence, in order to make them fully compliant with the minimum standards, wherever possible. The workshop was led by Helen Roy (CEH) and Riccardo Scalera (ISSG). An additional 16 experts from fifteen member states were selected based on their expertise in invasion biology and represented a breadth of expertise from a variety of perspectives including taxonomic (all taxa), environmental (freshwater, marine and terrestrial), impacts (environmental, socio-economic and health) and disciplines (ecologists, conservation practitioners, scientists, policy-makers, risk assessors). In view of the gaps across risk assessments for ecosystem services and climate change two experts were invited to guide the development of approaches for these specific themes. In total the risk assessments for 56 species were considered. The GB NNRA and EPPO DSS have published IAS risk assessments which, when considering species that score medium to high impact, together cover 51 species (noting that Fallopia japonica and F. sachalinensis are separate species). Two further risk assessments were suggested for consideration by the GB Non-Native Species Secretariat which follow the GB NNRA protocol: coati (Nasua nasua) and skunk (Mephitis mephitis), although scored as low impact. Finally an additional three species have been considered through new European–wide risk assessments, with the reported outcome of high impact, for this project which again follow the GB NNRA protocol: Pallas squirrel (Callosciurus erythraeus), grey squirrel (Sciurus carolinensis) and coypu (Myocastor coypus). The main gaps across all risk assessments were in relation to climate change and ecosystem services but additional information was also required on benefits as mentioned with minimum standard “Description (Taxonomy, invasion history, distribution range (native and introduced), geographic scope, socio-economic benefits)” and in some cases information to support the minimum standard “Includes status (threatened or protected) of species or habitat under threat“ was missing. It was agreed that systematic consideration of a list of questions in relation to the minimum standards on ecosystem services and climate change would be useful guidance for experts. An outline of the approaches agreed through the workshop for the minimum standards “Includes possible effects of climate change in the foreseeable future“ and “Can broadly assess environmental impact with respect to ecosystem services” were developed as guidance for documenting information in relation to climate change and ecosystem services. Each species was considered separately with the experts providing an overview of the information available for addressing the identified gaps. After all species had been considered the workshop participants (excluding the EC, Helen Roy and Riccardo Scalera) adopted a consensus approach to confirm whether or not the risk assessment was compliant with the minimum standards and whether the overall score of the risk assessment remained applicable. No changes were made to the scores but any recommendations were noted. There were very few recommendations for change. The outcome for each risk assessment was agreed and summarised as “compliant” or “not compliant” with the minimum standards. Of the risk assessments for the 56 species considered through this project, 53 were agreed to be fully compliant with the minimum standards. However, Pacific oyster, Crassostrea gigas, although compliant with the minimum standards should be excluded as it is not within the scope of the regulation (see art 2.e) because it is listed in annex IV of Council Regulation (EC) No 708/2007 of 11 June 2007 concerning use of alien and locally absent species in aquaculture. Four of the risk assessments were not considered to be compliant because of major information gaps: Elodea canadensis (Canadian pondweed), Heracleum mantegazzianum (giant hogweed), M. mephitis (skunk), N. nasua (coati)

A systematic review of the relationship between rumination and suicidality

Rumination has been persistently implicated in the etiology of hopelessness and depression: proximal predictors of suicidality. As a result, research has started to examine the role of rumination in suicidality. This systematic review aims to: (i) provide a concise synopsis of the current progress in examining the relationship between rumination and suicidality; and (ii) highlight areas for future research. To this end, a search of the international literature was conducted using the three main psychological and medical databases (Psych Info [1887-October 2007], Medline [1966-October 2007] and Web of Knowledge [1981-October 2007]). Eleven studies were identified providing evidence, with one exception, of a relationship between rumination and suicidality. This systematic review has highlighted a considerable dearth of studies, specifically of case-control and prospective, clinical studies, in the worldwide literature. Key areas for future research are discussed
