AbstractMany species are shifting their ranges to keep pace with climate change, but habitat fragmentation and limited dispersal could impede these range shifts. In the case of climate-vulnerable foundation species such as tropical reef corals and temperate forest trees, such limitations might put entire communities at risk of extinction. Restoring connectivity through corridors, stepping-stones, or enhanced quality of existing patches could prevent the extinction of several species, but dispersal-limited species might not benefit if other species block their dispersal. Alternatively, managers might relocate vulnerable species between habitats through assisted migration, but this is generally a species-by-species approach. To evaluate the relative efficacy of these strategies, we simulated the climate-tracking of species in randomized competitive metacommunities with alternative management interventions. We found that corridors and assisted migration were the most effective strategies at reducing extinction. Assisted migration was especially effective at reducing the extinction likelihood for short-dispersing species, but it often required moving several species repeatedly. Assisted migration was more effective at reducing extinction in environments with higher stochasticity, and corridors were more effective at reducing extinction in environments with lower stochasticity. We discuss the application of these approaches to an array of systems ranging from tropical corals to temperate forests.

Background: Appropriate mobile-based self-management strategies can be as new approaches to decelerate the HIV infection progression and improve the quality of life. This study aims at (i) identifying in the literature mobile-based self-management strategies for HIV care and (ii) prioritizing those from the point of view of infectious diseases specialists. This study provides some clues to design useful mobile-based self-management tools for HIV patients, from the point of view of practitioners. Methods: This mixed methods study was done in two main phases. In the first phase, a review was conducted in: PubMed, Web of Science, Science Direct, Scopus, and Ovid. In this manner, related studies published between 2010 and 2017 and in the English language were reviewed. In the second phase, identified mobile-based self-management strategies were scored and prioritized by 23 participants. Frequency distribution and mean reports were calculated using SPSS statistical software. Results: By detailed reviewing of 24 related articles, the HIV mobile-based self-management strategies were identified in 47 categories and subcategories. According to the findings, "enhance the quality of life" was the main self-management strategy addressed by reviewed studies. However, "antiretroviral therapy and medication adherence" was reported at a higher rate to be a more helpful strategy than "enhance the quality of life". Conclusion: In this study, helpful HIV mobile-based self-management strategies were identified that can be used to guide self-management interventions which have the potential to improve the healthcare services for people living with HIV.

Evidence-based practices (EBPs) are strategies shown through rigorous experimentation to be effective when implemented as designed by educators in the field. The purpose of this review is to (a) describe the state and quality of evidence-based reviews and meta-analyses of studies on classroom and behavior management interventions for students with emotional and behavioral disorders (EBDs) and (b) summarize practices which can be deemed evidence-based. We identified 50 meta-analytic or systematic reviews, encompassing 20 interventions implemented solely or in part with students with EBD. In total, our review identified eight interventions classified as EBPs for supporting students labeled with EBD in the meta-analytic literature. Implications for future research are presented.

Background: Pain in Parkinson’s is problematic but under treated in clinical practice. Healthcare professionals must understand the impact of pain in Parkinson’s and patient preferences for management. Objective: To understand the impact of pain in Parkinson’s and to understand current management and preferences for pain management. Methods: We conducted a national survey with 115 people with Parkinson’s (PwP) and 10 carers. Both closed and open questions were used. The questions focused on how pain affected the individual, healthcare professional involvement in supporting pain management, current pain management strategies and views on future pain management interventions. We used descriptive statistics to summarize closed responses and thematic analysis to summarize open question responses. Results: 70% of participants reported pain impacted their daily life. Pain had a multifactorial impact on participants, affecting movement, mood and quality of life. Improved pain management was viewed to have the potential to address each of these challenges. Pain affected a number of different sites, with low back pain and multiple sites being most frequently reported. Exercise was the most frequently noted strategy (38%) recommended by healthcare professionals for pain management. PwP would value involvement from healthcare professionals for future pain management, but also would like to self-manage the condition. Medication was not suggested as a first line strategy. Conclusions: Despite reporting engagement in some strategies to manage pain, pain still has a wide-ranging impact on the daily life of PwP. Results from this survey highlight the need to better support PwP to manage the impact of pain.

Tomato spotted wilt virus (TSWV) is the type member of the genus Orthotospovirus in the family Tospoviridae and order Bunyavirales. TSWV, transmitted by several species of thrips, causes significant disease losses to agronomic and horticultural crops worldwide, impacting both the yield and quality of the produce. Management strategies include growing virus-resistant cultivars, cultural practices, and managing thrips vectors through pesticide application. However, numerous studies have reported that TSWV isolates can overcome host-plant resistance, while thrips are developing resistance to pesticides that were once effective. RNA interference (RNAi) offers a means of host defence by using double-stranded (ds) RNA to initiate gene silencing against invading viruses. However, adoption of this approach requires production and use of transgenic plants and thus limits the practical application of RNAi against TSWV and other viruses. To fully utilize the potential of RNAi for virus management at the field level, new and novel approaches are needed. In this review, we summarize RNAi and highlight the potential of topical or exogenous application of RNAi triggers for managing TSWV and thrips vectors.

ObjectiveTo perform a systematic review (SR) on the effectiveness of self-management interventions, in order to inform the European League Against Rheumatism Recommendations for its implementation in patients with inflammatory arthritis (IA).MethodsThe SR was conducted according to the Cochrane Handbook and included adults (≥18 years) with IA. The search strategy was run in Medline through PubMed, Embase, Cochrane Library, CINAHL Plus with Full Text, and PEDro. The assessment of risk of bias, data extraction and synthesis were performed by two reviewers independently. A narrative Summary of Findings was provided according to the Grading of Recommendations, Assessment, Development and Evaluation.ResultsFrom a total 1577 references, 57 were selected for a full-text review, and 32 studies fulfilled the inclusion criteria (19 randomised controlled trials (RCTs) and 13 SRs). The most studied self-management components were specific interactive disease education in ten RCTs, problem solving in nine RCTs, cognitive–behavioural therapy in eight RCTs, goal setting in six RCTs, patient education in five RCTs and response training in two RCTs. The most studied interventions were multicomponent or single exercise/physical activity in six SRs, psychosocial interventions in five SRs and education in two SRs. Overall, all these specific components and interventions of self-management have beneficial effects on IAs-related outcomes.ConclusionsThe findings confirm the beneficial effect of the self-management interventions in IA and the importance of their implementation. Further research should focus on the understanding that self-management is a complex intervention to allow the isolation of the effectiveness of its different components.

Background: People with multiple sclerosis (MS) experience myriad symptoms that negatively affect their quality of life. Despite significant progress in rehabilitation strategies for people living with relapsing-remitting MS (RRMS), the development of similar strategies for people with progressive MS has received little attention. Objective: To highlight key symptoms of importance to people with progressive MS and stimulate the design and implementation of high-quality studies focused on symptom management and rehabilitation. Methods: A group of international research experts, representatives from industry, and people affected by progressive MS was convened by the International Progressive MS Alliance to devise research priorities for addressing symptoms in progressive MS. Results: Based on information from the MS community, we outline a rationale for highlighting four symptoms of particular interest: fatigue, mobility and upper extremity impairment, pain, and cognitive impairment. Factors such as depression, resilience, comorbidities, and psychosocial support are described, as they affect treatment efficacy. Conclusions: This coordinated call to action—to the research community to prioritize investigation of effective symptom management strategies, and to funders to support them—is an important step in addressing gaps in rehabilitation research for people affected by progressive MS.

Introduction Hypertension is a life-limiting, chronic condition affecting millions of Americans. Modifiable factors, quality of the patient-provider interaction and functional health literacy, have been linked to effective hypertension self-management. However, there has been limited interventional research targeting these modifiable factors. Electronic hypertension self-management interventions, in particular those incorporating virtual simulation, may positively influence the quality of the patient-provider interaction and functional health literacy status of adults with hypertension. Yet there is a dearth of evidence examining the efficacy of eHealth interventions targeting these modifiable factors of hypertension self-management. Objective Evaluate the effects of two electronic hypertension self-management interventions on the quality of the patient-provider interaction and functional health literacy in adults with hypertension. Methods A convenience sample of community-dwelling adults (>18 years) with hypertension were recruited and randomized to an avatar-based simulation (eSMART-HTN) or a video presentation on hypertension self-management (attention control). Participants were administered questionnaires to capture demographic characteristics, the quality of the patient-provider interaction, and functional health literacy. Questionnaire data were collected at baseline, and then monthly across three months. Two separate repeated measures analysis of covariance models were conducted to assess the effects of the interventions across the time points. Results The sample included 109 participants who were predominately middle-aged and older, nonwhite, and female. Scores for the quality of the patient-provider interaction demonstrated significant within-group changes across time. However, there were no significant differences in the quality of the patient-provider interaction or functional health literacy scores between experimental conditions while adjusting for covariates. Conclusion An avatar-based simulation (eSMART-HTN) intervention proved to have a positive effect on patient-provider interaction compared to an attention control condition. Although the results are promising, future research is needed to optimize the effectiveness of eSMART-HTN and enhance its efficacy and scalability in a larger cohort of adults with hypertension.

Starting from statistical data derived from the oncological field, some articles have highlighted the importance of communication in the patient–caregiver dyad and have considered the various roles involved in a cancer diagnosis situation. Thus, the question of how to intervene in terms of “quality of life” from the time of diagnosis to the recovery or death of a cancer patient, beyond the sanitary and physical dimensions, has become relevant. Therefore, the present narrative review aims to offer an overview of the state of the art in terms of the psychological treatment modalities of cancer patients, from the diagnosis to the post-surgery period. A total of 67 articles were collected and analyzed, in relation to (1) psychological constructs employed in the oncological field, (2) intervention models and (3) quality of life and well-being measurement and evaluation tools. We described these articles, differentiating between those focusing on the role of (1) the patient, (2) the caregiver, (3) the patient–caregiver dyad and (4) healthcare professional roles. The oncological diagnosis and its repercussions in the lives of the patient and caregiver were explored and critical aspects that emerged from the literature were highlighted. In conclusion, the analysis allowed some considerations about the need to define research protocols and useful management strategies for increasing the overall health of patients with cancer diagnoses and the people who surround them.

Anxiety is a common co-occurring condition in autism and impacts quality of life of autistic individuals and their families; autistic individuals who speak few or no words represent an under-researched group. This qualitative study aimed to understand more about parental recognition and management of anxiety in autistic individuals who speak few or no words. Semi-structured interviews were conducted with parents/carers of 17 autistic individuals (mage = 14.29) recruited from an existing participant database and social media adverts. Using thematic analysis, 15 themes were placed under three a-priori grand themes: parental recognition of anxiety; parental management of anxiety; and anxiety impact on the autistic individual and their family. Due to reduced verbal language use and overlap with other behaviours, parents described difficulties recognising anxiety in their child. However, they also described use of a number of management strategies, including some which overlap with components of evidence-based interventions for emotional and behavioural problems in autistic individuals (e.g. exposure/sensory calming). Despite this, parents reported that anxiety continues to have significant impact on quality of life. The findings of this study can help to inform the development of targeted intervention and assessment measures for anxiety in autistic individuals who speak few or no words. Lay abstract Anxiety is a common condition in autistic individuals, including those who also have an intellectual disability. Despite this, autistic individuals who have severe to profound intellectual disability, or use few or no words, are often excluded from autism research. There are also very few assessment tools and interventions with known effectiveness for autistic individuals with intellectual disability. In this study, we aimed to learn more about parent/carers experiences of recognising and managing anxiety in autistic individuals who use few or no words. We conducted semi-structured interviews with parents and carers to address three research questions: (1) what techniques and management strategies do parents describe for anxiety-related behaviour in their child; (2) how do communication difficulties impact parental understanding and management of anxiety provoking situations and behaviours; (3) what is the impact of anxiety-related behaviours on the quality of life of autistic individuals and their families? During the interviews, parents described difficulties recognising anxiety in their child, mostly due to reduced verbal language use and anxiety behaviours overlapping with other behaviours (e.g. autism characteristics). However, parents also described use of a number of management strategies, including some which overlap with components of evidence-based interventions for emotional and behavioural problems in autistic individuals (e.g. exposure/sensory calming). Despite this, parents reported that anxiety continues to have significant impact on quality of life. We will use the findings of this study to inform future research to develop assessment tools and interventions for anxiety in autistic individuals who use few or no words.
