Inclusion of People With Aphasia in Stroke Trials: A Systematic Search and Review.

BACKGROUND: Although people with aphasia (PwA) represent 30% of stroke survivors, they are frequently excluded from stroke research, or their inclusion is unclear. Such practice significantly limits the generalizability of stroke research, increases the need to duplicate research in aphasia-specific populations, and raises important ethical and human rights issues. OBJECTIVE: To detail the extent and nature of inclusion of PwA in contemporary stroke randomized controlled trials (RCTs). METHODS: We conducted a systematic search to identify completed stroke RCTs and RCT protocols published in 2019. Web of Science was searched using terms "stroke" and "randomized controlled trial". These articles were reviewed by extracting rates of PwA inclusion/exclusion, whether "aphasia" or related terms were referred to in the article or supplemental files, eligibility criteria, consent procedures, adaptations made to support the inclusion of PwA, and attrition rates of PwA. Data were summarized, and descriptive statistics applied when appropriate. RESULTS: 271 studies comprising 215 completed RCTs and 56 protocols were included. 36.2% of included studies referred to aphasia/dysphasia. Of completed RCTs, only 6.5% explicitly included PwA, 4.7% explicitly excluded PwA, and inclusion was unclear in the remaining 88.8%. Among RCT protocols, 28.6% of studies intended inclusion, 10.7% intended excluding PwA, and in 60.7%, inclusion was unclear. In 45.8% of included studies, sub-groups of PwA were excluded, either explicitly (ie, particular types/severities of aphasia, eg, global aphasia) or implicitly, by way of ambiguous eligibility criteria which could potentially relate to a sub-group of PwA. Little rationale for exclusion was provided. 71.2% of completed RCTs did not report any adaptations that could support the inclusion of PwA, and minimal information was provided about consent procedures. Where it could be determined, attrition of PwA averaged 10% (range 0%-20%). CONCLUSION: This paper details the extent of inclusion of PwA in stroke research and highlights opportunities for improvement.

Aphasia, depression, and psychological therapy (ADaPT): A single case design evaluation of a modified cognitive behavioural therapy to treat depressive symptoms in stroke survivors with aphasia.

Cognitive behavioural therapy (CBT) can effectively treat depression in the general population, but there is a lack of studies evaluating CBT tailored to specific cognitive and communication needs of individuals with post-stroke aphasia. We aimed to evaluate the feasibility and preliminary efficacy of a modified CBT intervention to ameliorate depressive symptoms. An ABA withdrawal/reversal single case design with concurrent multiple baselines (2.5, 4.5, or 6.5 weeks) was repeated across 10 participants (six male, four female) with post-stroke aphasia and self-reported depression. Participants completed 10 individual intervention sessions with a clinical neuropsychologist and a 4-week follow-up. The primary outcome was self-rated depression, and secondary outcomes included observer-rated symptoms of depression and anxiety. Data were analysed visually and statistically controlling for baseline trend. Feasibility was addressed by analysing recruitment and retention rates, treatment adaptations, and fidelity ratings. Three participants self-reported decreased depression levels during the intervention phase, which was sustained for two participants. Four additional participants improved during the follow-up phase. Close others reported sustained improvements in depressive symptoms (six participants) and anxiety symptoms (seven participants). Modified CBT appears feasible and potentially efficacious in reducing depressive symptoms in post-stroke aphasia. A randomized controlled trial is warranted, and should consider additional treatment sessions.

A survey of speech pathologists' opinions about the prospective acceptability of an online implementation platform for aphasia services.

BACKGROUND: Online knowledge translation (KT) approaches are becoming increasingly prevalent within healthcare due to their accessibility and facilitation of international support networks. Online platforms enable timely and far-reaching dissemination of current evidence and best-practice recommendations. Although there is potential to improve the uptake of rehabilitation guidelines, it is essential to consider the acceptability of online approaches to healthcare professionals to ensure their successful integration within everyday clinical settings. AIMS: To establish the prospective acceptability of a theoretically informed online intervention for speech pathologists, Aphasia Nexus: Connecting Evidence to Practice, that aims to facilitate the implementation of aphasia best practice. METHODS & PROCEDURES: A mixed-methods multinational electronic survey based on the Theoretical Framework of Acceptability (TFA) completed by aphasia researchers and clinicians. OUTCOMES & RESULTS: A total of 43 participants completed the survey with 91% (n = 39) indicating that they would use Aphasia Nexus. Understanding the intervention and how it works (intervention coherence as per the TFA) was the key factor influencing the likelihood of integration within everyday clinical practice. Participants identified potential areas where the intervention could influence service change and also recommended further design and content changes to improve the intervention. CONCLUSIONS & IMPLICATIONS: Aphasia Nexus is an acceptable platform for further feasibility testing in the form of a pilot trial within an Australian-based health service. The study progresses the theory of TFA as it was a valuable framework facilitating the identification of prominent factors influencing acceptability. The study also informs further intervention refinements in preparation for the next stage of research. WHAT THIS PAPER ADDS: What is already known on the subject Online strategies have the potential to enhance KT and promote the uptake of rehabilitation guidelines. An online intervention, however, can only be effective if implemented well. For this reason, it is essential to establish the acceptability of online interventions to the intended recipients and therefore increase the likelihood of successful implementation. What this paper adds to existing knowledge This study used a theoretically based framework to establish the acceptability of an online implementation intervention, Aphasia Nexus, to multinational aphasia clinicians and researchers. It demonstrated the value in identifying the prominent factors influencing acceptability to inform further intervention refinements and warrant continuing research. What are the potential or actual clinical implications of this work? Speech pathologists should use online platforms to drive the implementation of best practice on an international scale. It is important for clinicians to have an in-depth understanding of online interventions and how they work to enhance their successful uptake into routine clinical practice. Aphasia Nexus is an acceptable online platform for implementing best practice in aphasia.

Prognostication in post-stroke aphasia: Perspectives of people with aphasia on receiving information about recovery.

Many people with aphasia (language impairment post-stroke) want to know their prognosis for recovery, yet current understanding of their experience of receiving prognoses is limited. Such insight is necessary to inform clinical practice in formulating and delivering aphasia prognoses, especially given the psycho-emotional distress and secondary adverse effects on recovery associated with conversations about prognosis. We sought an in-depth understanding of the perspectives of people with aphasia in relation to receiving prognoses post-stroke, with the aim of informing an evidence-based approach to aphasia prognostication in clinical practice. Semi-structured interviews, facilitated by communication support strategies, were conducted one-to-one with eight people with aphasia (ranging from mild to very severe) 3-12 months post-stroke. Reflexive thematic analysis was used to analyse the qualitative data, yielding two over-arching themes: (1) How would you know without knowing me?; (2) I need to know, but I don't want to know. Our findings illustrate issues of mistrust within the patient-clinician relationship, and complex emotions relating to hope and post-stroke adjustment. The present insight into the lived experience of receiving aphasia prognoses highlights the need for focused consideration of personal definitions of normalcy, measures for fostering trust, and the role of prognostic uncertainty.

Towards the Consistent Inclusion of People With Aphasia in Stroke Research Irrespective of Discipline.

People with aphasia have been systematically excluded from stroke research or included without the necessary modifications, threatening external study validity. In this paper, we propose that 1) the inclusion of people with aphasia should be considered as standard in stroke research irrespective of discipline and that 2) modifications should be made to stroke research procedures to support people with aphasia to achieve meaningful and valid inclusion. We argue that outright exclusion of this heterogenous population from stroke research based purely on a diagnosis of aphasia is rarely required and present a rationale for deliberate inclusion of people with aphasia in stroke research. The purpose of this paper is fourfold: 1) to highlight the issue and implications of excluding people with aphasia from stroke research; 2) to acknowledge the current barriers to including people with aphasia in stroke research; 3) to provide stroke researchers with methods to enable inclusion, including recommendations, resources, and guidance; and 4) to consider research needed to develop aphasia inclusive practices in stroke research.

How Do Audiologists Respond to Emotional and Psychological Concerns Raised in the Audiology Setting? Three Case Vignettes.

OBJECTIVES: Emotional and psychological well-being are essential to overall health, but there is little research showing how to approach emotional and psychological concerns in the audiological setting. This study investigated audiologists' self-reported clinical behaviors in response to emotional and psychological concerns and/or symptoms raised by audiology clients. DESIGN: A sample of 83 Australia-based audiologists completed a survey including vignettes presenting older adults with hearing loss and experiencing symptoms consistent with either depression or grief. Content analysis was used to explore: (1) audiologists' self-reported usual response when clients present with emotional and psychological concerns and/or symptoms in the audiological setting; (2) audiologists' ability to identify and describe psychological symptoms; and (3) audiologists' self-reported clinical behaviors relating to client referral for psychological support. RESULTS: When asked to describe their usual clinical course of action in response to the vignettes, over one half the audiologists described actions that address the clients concerns related to psychological well-being. Where audiologists described how they would provide psychological support, they described modifications to the audiological rehabilitation program including involving significant others in the rehabilitation process, recommending additional support outside of the audiology setting (such as General Practitioner or psychologists), and providing emotional support and counseling. When prompted, the majority of participants recognized the two cases with depression as having a mental health condition; however, 48% of participants indicated the control case as also having a mental health condition. When asked directly, the majority of audiologists indicated that they would refer the three vignettes for specialist support; however, less than one third described referral to a General Practitioner and less than 5% described referral to a mental health professional as their normal course of action in the open response item. Twenty-five different professions/people were reported as potential sources for referral. CONCLUSION: These findings support the need for further training and/or resources for audiologists to enable them to appropriately detect, describe and refer for emotional and psychological concerns and/or symptoms raised by clients' in the audiology setting.

Help-seeking and people with aphasia who have mood problems after stroke: perspectives of speech-language pathologists.

BACKGROUND: Access to treatments for mood disorders may pose a challenge to individuals with compromised communication ability. Speech-language pathologists (SLPs) have previously reported that their clients with aphasia decline formal psychological support; however, their role in their clients' help-seeking has not been explored. AIMS: To investigate SLPs' perspectives on how they currently support help-seeking for mood problems in people with aphasia and factors they perceive to be impacting service uptake. METHODS & PROCEDURES: A qualitative interview study was conducted. SLPs in Australia working with people with aphasia in a clinical role were recruited. Transcripts of the interviews were subject to qualitative analysis to identify relevant themes. OUTCOMES & RESULTS: Eighteen interviews were conducted. One overarching theme and three sub-themes were identified as central to SLPs' experience. The overarching theme was of a 'double whammy' impact on help-seeking: people with aphasia were subject to universal barriers associated with seeking help as well as additional barriers imposed by compromised communication. Three themes contributed to the overarching theme: (1) SLPs' understanding of barriers and facilitators to patients with aphasia seeking help; (2) the role of the SLP as a skilled helper for mood management; and (3) mood and communication as competing rehabilitation priorities. CONCLUSIONS & IMPLICATIONS: SLPs report both universal barriers to help-seeking and those specific to their clients with aphasia and attempts to overcome these; however, there appears to be a dearth of accessible mental health services for people with aphasia known to SLPs, including psychological/counselling professionals who are skilled in communicating with people with aphasia. Health professionals working within and across post-stroke and mental health services should recognize that people with post-stroke aphasia are susceptible to a decline in mental health, are amenable to formal (and tailored) psychological support, and can be supported to seek help.

"We don't know what we don't know": Providing information about communication to families of children with Down syndrome.

PURPOSE: Children with Down syndrome often present with a communication disability, and families require information to support their child's communication. Effective provision of information by professionals is an important part of family-centred practice. However, we currently do not know the specific communication information needs of families of children with Down syndrome. This study aimed to (1) explore families' experiences of communication information provision and (2) identify families' preferences regarding when, what and how they would like to receive information about communication. METHOD: A qualitative descriptive approach was used to explore the experiences and information needs of nine family members of children with Down syndrome aged 0-15 years. Data from semistructured, in-depth interviews were analysed using thematic analysis. RESULTS: Three core themes were identified: (1) We want more information about communication to be provided by professionals now and into the future so we can be "self-help people." (2) We want general information resources that help us support our child's communication. (3) We want to have a two-way partnership with professionals so we can share and receive specific information about our child's communication. CONCLUSION: Ineffective information provision restricts families' capacity to be self-help people in supporting communication development. Ongoing provision of both general and specific information about communication is needed in different formats. This study informs the development of resources to better meet families' information needs.

Accessibility and Applicability of Currently Available e-Mental Health Programs for Depression for People With Poststroke Aphasia: Scoping Review.

BACKGROUND: Depression affects approximately 60% of people with aphasia 1 year post stroke and is associated with disability, lower quality of life, and mortality. Web-delivered mental health (e-mental health) programs are effective, convenient, and cost-effective for the general population and thus are increasingly used in the management of depression. However, it is unknown if such services are applicable and communicatively accessible to people with poststroke aphasia. OBJECTIVE: The aim of this study was to identify freely available e-mental health programs for depression and determine their applicability and accessibility for people with poststroke aphasia. METHODS: A Web-based search was conducted to identify and review freely available e-mental health programs for depression. These programs were then evaluated in terms of their (1) general features via a general evaluation tool, (2) communicative accessibility for people with aphasia via an aphasia-specific communicative accessibility evaluation tool, and (3) empirical evidence for the general population and stroke survivors with and without aphasia. The program that met the most general evaluation criteria and aphasia-specific communicative accessibility evaluation criteria was then trialed by a small subgroup of people with poststroke aphasia. RESULTS: A total of 8 programs were identified. Of these, 4 had published evidence in support of their efficacy for use within the general population. However, no empirical evidence was identified that specifically supported any programs' use for stroke survivors with or without aphasia. One evidence-based program scored at least 80% (16/19 and 16/20, respectively) on both the general and aphasia-specific communicative accessibility evaluation tools and was subject to a preliminary trial by 3 people with poststroke aphasia. During this trial, participants were either unable to independently use the program or gave it low usability scores on a post-trial satisfaction survey. On this basis, further evaluation was considered unwarranted. CONCLUSIONS: Despite fulfilling majority of the general evaluation and aphasia-specific evaluation criteria, the highest rated program was still found to be unsuitable for people with poststroke aphasia. Thus, e-mental health programs require substantial redevelopment if they are likely to be useful to people with poststroke aphasia.

Determinants of Living Well With Aphasia in the First Year Poststroke: A Prospective Cohort Study.

OBJECTIVE: To determine factors that contribute to living well with aphasia in the first 12 months poststroke. DESIGN: Prospective longitudinal cohort study. SETTING: Hospitalized care, ambulatory care, and general community. PARTICIPANTS: A referred sample of people (N=58) with a first incidence of aphasia after stroke was assessed at 3, 6, 9, and 12 months postonset. Participants were recruited through speech-language pathologists in 2 capital cities in Australia. Presence of aphasia was determined through the Western Aphasia Battery-Revised by an experienced speech-language pathologist. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The main outcomes were the 5 domains of the Assessment for Living with Aphasia at 3, 6, 9, and 12 months poststroke. The independent variables included demographics, physical functioning, social network, mood, aphasia severity, and a self-rating of successfully living with aphasia at the same time points. Mixed effects modeling was used to determine which factors contributed to the trajectory of each of the 5 domains of participation, impairment, environment, personal factors, and life with aphasia. RESULTS: Higher household income, larger social network size, being a woman, and having milder aphasia were positively associated with the participation domain. Graduate or postgraduate educational levels, low mood, and poor physical functioning were negatively associated with the participation domain. Factors positively associated with other domains included higher income, self-ratings of successfully living with aphasia, and aphasia severity. Low mood was consistently negatively associated with all of the domains. CONCLUSIONS: Psychosocial determinants were the most significant predictors of living well with aphasia in the first 12 months postonset. Aphasia rehabilitation needs to attend more to these factors to optimize outcomes.

Features of an Intensive Care based Medical Emergency Team nurse training program in a University Teaching Hospital.

BACKGROUND: Medical Emergency Teams (METs) involve specialist staff who respond to acutely deteriorating ward patients. There is little literature describing the scope of practice and training of MET responders. PURPOSE: To describe and discuss an education and training program for Intensive Care Unit (ICU) nurses who function in a high capability teaching hospital MET. FINDINGS: The program is overseen and coordinated by four senior nurses. Applicants require at least three years experience working as an ICU nurse in a level 3 tertiary ICU. Each program participant is allocated a mentor and must complete the program within six months. Induction involves attending lectures outlining expected roles, responsibilities and appropriate conduct during MET calls. A course handbook outlines a series of competencies including checking of the MET trolley, assisting endo-tracheal intubation, commencement of non-invasive ventilation and high flow oxygen. Each participant attends the first five MET calls under supervision. A series of case scenarios are discussed and reviewed and an oral examination on two such cases is undertaken prior to completion of the program. Throughout, candidates are trained in their expected roles and responsibilities during MET calls, follow-up of at-risk and deteriorating patients, emergency calls in the mental health precinct, and assisting with procedures outside of the ICU. Emphasis is placed on both technical and non-technical skills. CONCLUSIONS: We have provided a framework for the development of a MET nurse training program. The applicability of this program to other settings and effects of this program on patient outcomes remain unknown.

Copper isotope fractionation during equilibration with natural and synthetic ligands.

As copper (Cu) stable isotopes emerge as a tool for tracing Cu biogeochemical cycling, an understanding of how Cu isotopes fractionate during complexation with soluble organic ligands in natural waters and soil solutions is required. A Donnan dialysis technique was employed to assess the isotopic fractionation of Cu during complexation with the soluble synthetic ligands ethylenediaminetetraacetic acid (EDTA), nitrilotriacetic acid (NTA), iminodiacetic acid (IDA) and desferrioxamine B (DFOB), as well as with Suwannee River fulvic acid (SRFA). The results indicated enrichment of the heavy isotope ((65)Cu) in the complexes, with Δ(65)Cu complex-free values ranging from +0.14 to +0.84‰. A strong linear correlation was found between the logarithms of the stability constants of the Cu complexes and the magnitudes of isotopic fractionation. These results show that complexation of Cu by organic ligands can affect the isotopic signature of the free Cu ion. This free Cu is considered the most bioavailable species, and hence, our results highlight the importance of understanding fractionation processes in the uptake medium when using Cu isotopes to study the uptake mechanisms of organisms. These data contribute a vital piece to the emerging picture of Cu isotope cycling in the natural environment, as organic complexation plays a key role in the Cu cycle.

The kitchen assessment: an interactional analysis of assessment and feedback between an occupational therapist and a patient with aphasia post stroke.

PURPOSE: After stroke, patients undergo frequent multidisciplinary assessments. Little is known about patients' experiences of being assessed and the impact of assessment interactions and feedback for ongoing engagement in rehabilitation. This research aims to stimulate reflection on clinical interactions, even during routine clinical assessments, and the provision of assessment feedback. MATERIALS AND METHODS: This study involved a detailed analysis of an authentic kitchen assessment interaction between an occupational therapist and a patient with aphasia following stroke. It used a speech function analysis based on systemic functional linguistics resulting in both dynamic and synoptic data, and a consideration of interactive framing, to explore assessment explanation and feedback. RESULTS: The analysis revealed the clinician's interactive dominance in terms of number and type of moves, and misalignment of interactional framing at different points in the exchange. The session appeared to result in patient disengagement related both to the clinician's misjudged response to the patient's aphasia, and the context of assessment itself, characterised by reliance on question-and-answer exchanges, and a tendency to highlight deficit. CONCLUSIONS: Assessment sessions may be emotionally challenging for patients after stroke and feedback may be interpreted as bad news. Sensitive communication is required to support psychological wellbeing and engagement in rehabilitation.IMPLICATIONS FOR REHABILITATIONAfter stroke, patients are assessed by the multidisciplinary team to inform intervention and discharge planning.Little is known about the feedback patients receive or their views of this feedback, including when it is perceived as bad news.The presence of aphasia can complicate how assessments are conducted and how feedback is delivered and received.Greater awareness is needed of how feedback following assessment might impact patients' psychological wellbeing and engagement in rehabilitation.

Aphasia Depression and Psychological Therapy (ADaPT): Perspectives of People with Post-Stroke Aphasia on Participating in a Modified Cognitive Behavioral Therapy.

Aphasia, a communication disability commonly caused by stroke, can profoundly affect a person's mood and identity. We explored the experiences of stroke survivors with aphasia and depression who received a modified cognitive behavioral therapy (CBT)-based psychological intervention. The therapy is manualized with a flexible treatment protocol, including 10 individually based therapy sessions (+2 booster sessions) either via telehealth or in person. Six participants with chronic aphasia (60% of the total sample) participated in in-depth interviews that were analyzed using reflexive thematic analysis. Two core themes were derived from the data: the first theme, helpful elements of therapy-doing enjoyable activities, new ways of thinking, problem solving, working with the experienced therapist, and using telehealth; and the second theme, making progress-mood, communication, acceptance of the 'new me', and improving relationships. All participants found the therapy to be helpful in managing mood problems with various elements being beneficial depending on the individual, highlighting the importance of tailoring the intervention. Therefore, delivering modified CBT to individuals with aphasia is likely to be acceptable both in person and through telehealth. Further evaluation of the intervention and its impact on mood would be beneficial.

Developing consensus-based clinical competencies to guide stroke clinicians in the implementation of psychological care in aphasia rehabilitation.

Background People with aphasia experience depression and anxiety associated with negative outcomes across a range of time post-stroke. Stroke clinicians are well-positioned to facilitate low-intensity psychotherapeutic interventions after aphasia (e.g. mood screening, behavioural activation, problem-solving therapy, relaxation therapy); however, they self-report a lack of knowledge, skills and confidence to do so. The Theoretical Domains Framework (TDF) provides a lens through which to view and target clinician behaviours and training needs in this area of practice. The aim of this study was to develop and gain consensus on items for a rating scale of clinical competencies in facilitating individual-based, low-intensity psychotherapeutic interventions for people with aphasia. Methods An e-Delphi methodology using focus groups and survey rounds was used to gain consensus on clinical competencies considered important. Results Eight stroke clinicians (speech pathologists and psychologists), two people with aphasia and three family members participated in one of four focus groups. Four themes were derived from the data: (1) Communication support, (2) Assessment and therapy structure, (3) Interpersonal skills, and (4) Needs of the significant other (family or friend). Themes informed an initial list of 23 self-rated and observer-rated competency items. Following two rounds of e-Delphi surveys, 11 stroke clinicians (six speech pathologists and five psychologists) reached consensus (80-100%) for 19 competencies. Conclusions The Psychological Care in Aphasia Rehabilitation Competency scale offers a preliminary list of items to guide and train clinicians to implement low-intensity psychotherapeutic interventions for people with aphasia.

Pressure injuries in mechanically ventilated COVID-19 patients utilising different prone positioning techniques - A prospective observational study.

OBJECTIVES: To compare the incidence and distribution of pressure injuries (PIs) with two approaches to prone positioning for mechanically ventilated COVID-19 patients, and to determine the prevalence of these PIs on intensive care unit (ICU) and hospital discharge. DESIGN: A prospective observational study. SETTING: Adult patients admitted to a quaternary ICU with COVID-19-associated acute lung injury, between September 2021 and February 2022. MAIN OUTCOME MEASURES: Incidence and anatomical distribution of PIs during ICU stay for "Face Down" and "Swimmers Position" as well as on ICU and hospital discharge. RESULTS: We investigated 206 prone episodes in 63 patients. In the Face Down group, 26 of 34 patients (76 %) developed at least one PI, compared to 10 of 22 patients (45 %) in the Swimmers Position group (p = 0.02). Compared to the Swimmers Position group, the Face Down group developed more pressure injuries per patient (median 1 [1, 3] vs 0 [0, 2], p = 0.04) and had more facial PIs (p = 0.002). In a multivariate logistic regression model, patients were more likely to have at least one PI with Face Down position (OR 4.67, 95 % CI 1.28, 17.04, p = 0.02) and greater number of prone episodes (OR 1.75, 95 % CI 1.12, 2.74, p = 0.01). Over 80 % of all PIs were either stage 1 or stage 2. By ICU discharge, 29 % had healed and by hospital discharge, 73 % of all PIs had healed. CONCLUSION: Swimmers Position had a significantly lower incidence of PIs compared to the Face Down approach. One-quarter of PIs had healed by time of ICU discharge and three-quarters by time of hospital discharge. IMPLICATIONS FOR CLINICAL PRACTICE: There are differences in incidence of PIs related to prone positioning approaches. This study validates and helps better inform current prone position guidelines recommending the use of Swimmers Position. The low prevalence of PIs at hospital discharge is reassuring.

Copper speciation and isotopic fractionation in plants: uptake and translocation mechanisms.

The fractionation of stable copper (Cu) isotopes during uptake into plant roots and translocation to shoots can provide information on Cu acquisition mechanisms. Isotope fractionation ((65) Cu/(63) Cu) and intact tissue speciation techniques (X-ray absorption spectroscopy, XAS) were used to examine the uptake, translocation and speciation of Cu in strategy I (tomato-Solanum lycopersicum) and strategy II (oat-Avena sativa) plant species. Plants were grown in controlled solution cultures, under varied iron (Fe) conditions, to test whether the stimulation of Fe-acquiring mechanisms can affect Cu uptake in plants. Isotopically light Cu was preferentially incorporated into tomatoes (Δ(65) Cu(whole plant-solution ) = c. -1‰), whereas oats showed minimal isotopic fractionation, with no effect of Fe supply in either species. The heavier isotope was preferentially translocated to shoots in tomato, whereas oat plants showed no significant fractionation during translocation. The majority of Cu in the roots and leaves of both species existed as sulfur-coordinated Cu(I) species resembling glutathione/cysteine-rich proteins. The presence of isotopically light Cu in tomatoes is attributed to a reductive uptake mechanism, and the isotopic shifts within various tissues are attributed to redox cycling during translocation. The lack of isotopic discrimination in oat plants suggests that Cu uptake and translocation are not redox selective.

Development of the "Kalmer" relaxation intervention: co-design with stroke survivors with aphasia.

PURPOSE: Anxiety is common after stroke and more prevalent in survivors with aphasia. Relaxation is an effective first-line therapy. The current study aimed to obtain the perspectives of stroke survivors with aphasia to inform the development of an accessible, technology-based, relaxation intervention. MATERIALS AND METHODS: Qualitative co-design methods were used with twelve people with aphasia after stroke. The "Kalmer" Relaxation treatment package materials were iteratively based on participants' experiences and preferences; barriers and facilitators to treatment compliance were explored. Participants were also asked to consider how the intervention might be evaluated in a research trial. RESULTS: A thematic analysis highlighted the importance and need for the development of an appropriate and inclusive relaxation product, to be implemented by health professionals early post-stroke. Several behavioural strategies to improve treatment adherence were recommended. Participants had varying perspectives on clinically meaningful treatment outcomes. CONCLUSIONS: Overall, a co-designed accessible relaxation product was viewed as a necessary component of usual stroke care. Acceptability and feasibility and preliminary efficacy of the "Kalmer" intervention should be trialled in future studies. IMPLICATIONS FOR REHABILITATIONCo-designing psychological interventions for people with aphasia after stroke is needed to meet the needs of this at-risk population.Technology-based relaxation interventions to manage anxiety after stroke are viewed positively by people with aphasia and deemed acceptable and feasible.Clinical trials of these co-designed relaxation interventions are required before recommending integration into routine practice.

Preventing depression in aphasia: A cluster randomized control trial of the Aphasia Action Success Knowledge (ASK) program.

BACKGROUND: Stroke patients with aphasia and their caregivers have higher incidence of depression than those without aphasia. AIMS: The objective of the study is to determine whether a tailored intervention program (Action Success Knowledge; ASK) led to better mood and quality of life (QoL) outcomes than an attention control with a 12-month end point at cluster and individual participant level. METHODS: A multi-site, pragmatic, two-level single-blind cluster randomized controlled trial compared ASK to an attention control (secondary stroke prevention program). Ten metropolitan and 10 non-metropolitan health regions were randomized. People with aphasia and their family members were recruited within 6 months post-stroke who scored ⩽12 on the Stroke Aphasic Depression Questionnaire Hospital Version-10 at screening. Each arm received manualized intervention over 6-8 weeks followed by monthly telephone calls. Blinded assessments of QoL and depression were taken at 12 months post-onset. RESULTS: Twenty clusters (health regions) were randomized. Trained speech pathologists screened 1744 people with aphasia and 373 participants consented to intervention (n = 231 people with aphasia and 142 family members). The attrition rate after consent was 26% with 86 and 85 participants with aphasia in the ASK arm and attention control arm, respectively, receiving intervention. Of those 171 who did receive treatment, only 41 met the prescribed minimum dose. Multilevel mixed effects modeling under the intention-to-treat protocol showed a significant difference on the Stroke and Aphasia Depression Questionnaire-21 (SADQ-21, N = 122, 17 clusters) in favor of the attention control (ß = -2.74, 95% confidence interval (CI) = -4.76 to -0.73, p = 0.008). Individual data analysis using a minimal detectable change score for the SADQ-21 showed the difference was not meaningful. CONCLUSION: ASK showed no benefit over attention control in improving mood and preventing depression in people with aphasia or their family members.

Evaluating the feasibility and acceptability of the Mood Assessment Post-Stroke (MAPS) mood screening training.

Mood problems are common after stroke, and screening is recommended. Training may support staff knowledge and implementation of screening, but the feasibility of training programmes in the Australian healthcare system has not been formally established. This study aimed to assess the feasibility of a mood screening training for a multidisciplinary team (MDT) of stroke clinicians working in a post-acute inpatient rehabilitation service.Twelve staff from a rehabilitation service at a major hospital in Sydney, Australia participated in a 3-h interactive training session. The feasibility of running the course, assessment of knowledge gained via a consolidation exercise and quiz and acceptability of the training were assessed via focus groups.The in-person modality of the training hindered recruitment and assessment of participants' knowledge, though the actual measures themselves appeared appropriate. Nine participants provided feedback in two focus groups. Thematic analysis identified positive reactions to the training. However, low self-efficacy persisted and organisational/socio-cultural barriers to implementation emerged. Following training, the medical officers of the MDT had successfully implemented routine screening.Overall, the training appeared acceptable and to foster knowledge in staff. However, limitations to recruitment and administering evaluations were identified. The development of flexible online training may improve future evaluations of screening training programmes/pathways.
