Communication to promote and support physical distancing for COVID-19 prevention and control.

BACKGROUND: This review is an update of a rapid review undertaken in 2020 to identify relevant, feasible and effective communication approaches to promote acceptance, uptake and adherence to physical distancing measures for COVID-19 prevention and control. The rapid review was published when little was known about transmission, treatment or future vaccination, and when physical distancing measures (isolation, quarantine, contact tracing, crowd avoidance, work and school measures) were the cornerstone of public health responses globally. This updated review includes more recent evidence to extend what we know about effective pandemic public health communication. This includes considerations of changes needed over time to maintain responsiveness to pandemic transmission waves, the (in)equities and variable needs of groups within communities due to the pandemic, and highlights again the critical role of effective communication as integral to the public health response. OBJECTIVES: To update the evidence on the question 'What are relevant, feasible and effective communication approaches to promote acceptance, uptake and adherence to physical distancing measures for COVID-19 prevention and control?', our primary focus was communication approaches to promote and support acceptance, uptake and adherence to physical distancing. SECONDARY OBJECTIVE: to explore and identify key elements of effective communication for physical distancing measures for different (diverse) populations and groups. SEARCH METHODS: We searched MEDLINE, Embase and Cochrane Library databases from inception, with searches for this update including the period 1 January 2020 to 18 August 2021. Systematic review and study repositories and grey literature sources were searched in August 2021 and guidelines identified for the eCOVID19 Recommendations Map were screened (November 2021). SELECTION CRITERIA: Guidelines or reviews focusing on communication (information, education, reminders, facilitating decision-making, skills acquisition, supporting behaviour change, support, involvement in decision-making) related to physical distancing measures for prevention and/or control of COVID-19 or selected other diseases (sudden acute respiratory syndrome (SARS), Middle East respiratory syndrome (MERS), influenza, Ebola virus disease (EVD) or tuberculosis (TB)) were included. New evidence was added to guidelines, reviews and primary studies included in the 2020 review. DATA COLLECTION AND ANALYSIS: Methods were based on the original rapid review, using methods developed by McMaster University and informed by Cochrane rapid review guidance. Screening, data extraction, quality assessment and synthesis were conducted by one author and checked by a second author. Synthesis of results was conducted using modified framework analysis, with themes from the original review used as an initial framework. MAIN RESULTS: This review update includes 68 studies, with 17 guidelines and 20 reviews added to the original 31 studies. Synthesis identified six major themes, which can be used to inform policy and decision-making related to planning and implementing communication about a public health emergency and measures to protect the community. Theme 1: Strengthening public trust and countering misinformation: essential foundations for effective public health communication Recognising the key role of public trust is essential. Working to build and maintain trust over time underpins the success of public health communications and, therefore, the effectiveness of public health prevention measures. Theme 2: Two-way communication: involving communities to improve the dissemination, accessibility and acceptability of information Two-way communication (engagement) with the public is needed over the course of a public health emergency: at first, recognition of a health threat (despite uncertainties), and regularly as public health measures are introduced or adjusted. Engagement needs to be embedded at all stages of the response and inform tailoring of communications and implementation of public health measures over time. Theme 3: Development of and preparation for public communication: target audience, equity and tailoring Communication and information must be tailored to reach all groups within populations, and explicitly consider existing inequities and the needs of disadvantaged groups, including those who are underserved, vulnerable, from diverse cultural or language groups, or who have lower educational attainment. Awareness that implementing public health measures may magnify existing or emerging inequities is also needed in response planning, enactment and adjustment over time. Theme 4: Public communication features: content, timing and duration, delivery Public communication needs to be based on clear, consistent, actionable and timely (up-to-date) information about preventive measures, including the benefits (whether for individual, social groupings or wider society), harms (likewise) and rationale for use, and include information about supports available to help follow recommended measures. Communication needs to occur through multiple channels and/or formats to build public trust and reach more of the community. Theme 5: Supporting behaviour change at individual and population levels Supporting implementation of public health measures with practical supports and services (e.g. essential supplies, financial support) is critical. Information about available supports must be widely disseminated and well understood. Supports and communication related to them require flexibility and tailoring to explicitly consider community needs, including those of vulnerable groups. Proactively monitoring and countering stigma related to preventive measures (e.g. quarantine) is also necessary to support adherence. Theme 6: Fostering and sustaining receptiveness and responsiveness to public health communication Efforts to foster and sustain public receptiveness and responsiveness to public health communication are needed throughout a public health emergency. Trust, acceptance and behaviours change over time, and communication needs to be adaptive and responsive to these changing needs. Ongoing community engagement efforts should inform communication and public health response measures. AUTHORS' CONCLUSIONS: Implications for practice Evidence highlights the critical role of communication throughout a public health emergency. Like any intervention, communication can be done well or poorly, but the consequences of poor communication during a pandemic may mean the difference between life and death. The approaches to effective communication identified in this review can be used by policymakers and decision-makers, working closely with communication teams, to plan, implement and adjust public communications over the course of a public health emergency like the COVID-19 pandemic. Implications for research Despite massive growth in research during the COVID-19 period, gaps in the evidence persist and require high-quality, meaningful research. This includes investigating the experiences of people at heightened COVID-19 risk, and identifying barriers to implementing public communication and protective health measures particular to lower- and middle-income countries, and how to overcome these.

Consumers' and health providers' views and perceptions of partnering to improve health services design, delivery and evaluation: a co-produced qualitative evidence synthesis.

BACKGROUND: Partnering with consumers in the planning, delivery and evaluation of health services is an essential component of person-centred care. There are many ways to partner with consumers to improve health services, including formal group partnerships (such as committees, boards or steering groups). However, consumers' and health providers' views and experiences of formal group partnerships remain unclear. In this qualitative evidence synthesis (QES), we focus specifically on formal group partnerships where health providers and consumers share decision-making about planning, delivering and/or evaluating health services. Formal group partnerships were selected because they are widely used throughout the world to improve person-centred care. For the purposes of this QES, the term 'consumer' refers to a person who is a patient, carer or community member who brings their perspective to health service partnerships. 'Health provider' refers to a person with a health policy, management, administrative or clinical role who participates in formal partnerships in an advisory or representative capacity. This QES was co-produced with a Stakeholder Panel of consumers and health providers. The QES was undertaken concurrently with a Cochrane intervention review entitled Effects of consumers and health providers working in partnership on health services planning, delivery and evaluation. OBJECTIVES: 1. To synthesise the views and experiences of consumers and health providers of formal partnership approaches that aimed to improve planning, delivery or evaluation of health services. 2. To identify best practice principles for formal partnership approaches in health services by understanding consumers' and health providers' views and experiences. SEARCH METHODS: We searched MEDLINE, Embase, PsycINFO and CINAHL for studies published between January 2000 and October 2018. We also searched grey literature sources including websites of relevant research and policy organisations involved in promoting person-centred care. SELECTION CRITERIA: We included qualitative studies that explored consumers' and health providers' perceptions and experiences of partnering in formal group formats to improve the planning, delivery or evaluation of health services. DATA COLLECTION AND ANALYSIS: Following completion of abstract and full-text screening, we used purposive sampling to select a sample of eligible studies that covered a range of pre-defined criteria, including rich data, range of countries and country income level, settings, participants, and types of partnership activities. A Framework Synthesis approach was used to synthesise the findings of the sample. We appraised the quality of each study using the CASP (Critical Appraisal Skill Program) tool. We assessed our confidence in the findings using the GRADE-CERQual (Confidence in the Evidence from Reviews of Qualitative research) approach. The Stakeholder Panel was involved in each stage of the review from development of the protocol to development of the best practice principles. MAIN RESULTS: We found 182 studies that were eligible for inclusion. From this group, we selected 33 studies to include in the final synthesis. These studies came from a wide range of countries including 28 from high-income countries and five from low- or middle-income countries (LMICs). Each of the studies included the experiences and views of consumers and/or health providers of partnering in formal group formats. The results were divided into the following categories. Contextual factors influencing partnerships: government policy, policy implementation processes and funding, as well as the organisational context of the health service, could facilitate or impede partnering (moderate level of confidence). Consumer recruitment: consumer recruitment occurred in different ways and consumers managed the recruitment process in a minority of studies only (high level of confidence). Recruiting a range of consumers who were reflective of the clinic's demographic population was considered desirable, particularly by health providers (high level of confidence). Some health providers perceived that individual consumers' experiences were not generalisable to the broader population whereas consumers perceived it could be problematic to aim to represent a broad range of community views (high level of confidence). Partnership dynamics and processes: positive interpersonal dynamics between health providers and consumers facilitated partnerships (high level of confidence). However, formal meeting formats and lack of clarity about the consumer role could constrain consumers' involvement (high level of confidence). Health providers' professional status, technical knowledge and use of jargon were intimidating for some consumers (high level of confidence) and consumers could feel their experiential knowledge was not valued (moderate level of confidence). Consumers could also become frustrated when health providers dominated the meeting agenda (moderate level of confidence) and when they experienced token involvement, such as a lack of decision-making power (high level of confidence) Perceived impacts on partnership participants: partnering could affect health provider and consumer participants in both positive and negative ways (high level of confidence). Perceived impacts on health service planning, delivery and evaluation: partnering was perceived to improve the person-centredness of health service culture (high level of confidence), improve the built environment of the health service (high level of confidence), improve health service design and delivery e.g. facilitate 'out of hours' services or treatment closer to home (high level of confidence), enhance community ownership of health services, particularly in LMICs (moderate level of confidence), and improve consumer involvement in strategic decision-making, under certain conditions (moderate level of confidence). There was limited evidence suggesting partnering may improve health service evaluation (very low level of confidence). Best practice principles for formal partnering to promote person-centred care were developed from these findings. The principles were developed collaboratively with the Stakeholder Panel and included leadership and health service culture; diversity; equity; mutual respect; shared vision and regular communication; shared agendas and decision-making; influence and sustainability. AUTHORS' CONCLUSIONS: Successful formal group partnerships with consumers require health providers to continually reflect and address power imbalances that may constrain consumers' participation. Such imbalances may be particularly acute in recruitment procedures, meeting structure and content and decision-making processes. Formal group partnerships were perceived to improve the physical environment of health services, the person-centredness of health service culture and health service design and delivery. Implementing the best practice principles may help to address power imbalances, strengthen formal partnering, improve the experiences of consumers and health providers and positively affect partnership outcomes.

Interventions for interpersonal communication about end of life care between health practitioners and affected people.

BACKGROUND: Communication about end of life (EoL) and EoL care is critically important for providing quality care as people approach death. Such communication is often complex and involves many people (patients, family members, carers, health professionals). How best to communicate with people in the period approaching death is not known, but is an important question for quality of care at EoL worldwide. This review fills a gap in the evidence on interpersonal communication (between people and health professionals) in the last year of life, focusing on interventions to improve interpersonal communication and patient, family member and carer outcomes. OBJECTIVES: To assess the effects of interventions designed to improve verbal interpersonal communication about EoL care between health practitioners and people affected by EoL. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, PsycINFO, and CINAHL from inception to July 2018, without language or date restrictions. We contacted authors of included studies and experts and searched reference lists to identify relevant papers. We searched grey literature sources, conference proceedings, and clinical trials registries in September 2019. Database searches were re-run in June 2021 and potentially relevant studies listed as awaiting classification or ongoing. SELECTION CRITERIA: This review assessed the effects of interventions, evaluated in randomised and quasi-randomised trials, intended to enhance interpersonal communication about EoL care between patients expected to die within 12 months, their family members and carers, and health practitioners involved in their care. Patients of any age from birth, in any setting or care context (e.g. acute catastrophic injury, chronic illness), and all health professionals involved in their care were eligible. All communication interventions were eligible, as long as they included interpersonal interaction(s) between patients and family members or carers and health professionals. Interventions could be simple or complex, with one or more communication aims (e.g. to inform, skill, engage, support). Effects were sought on outcomes for patients, family and carers, health professionals and health systems, including adverse (unintended) effects. To ensure this review's focus was maintained on interpersonal communication in the last 12 months of life,  we excluded studies that addressed specific decisions, shared or otherwise, and the tools involved in such decision-making. We also excluded studies focused on advance care planning (ACP) reporting ACP uptake or completion as the primary outcome. Finally, we excluded studies of communication skills training for health professionals unless patient outcomes were reported as primary outcomes. DATA COLLECTION AND ANALYSIS: Standard Cochrane methods were used, including dual review author study selection, data extraction and quality assessment of the included studies. MAIN RESULTS: Eight trials were included. All assessed intervention effects compared with usual care. Certainty of the evidence was low or very low. All outcomes were downgraded for indirectness based on the review's purpose, and many were downgraded for imprecision and/or inconsistency. Certainty was not commonly downgraded for methodological limitations. A summary of the review's findings is as follows. Knowledge and understanding (four studies, low-certainty evidence; one study without usable data): interventions to improve communication (e.g. question prompt list, with or without patient and physician training) may have little or no effect on knowledge of illness and prognosis, or information needs and preferences, although studies were small and measures used varied across trials.  Evaluation of the communication (six studies measuring several constructs (communication quality, patient-centredness, involvement preferences, doctor-patient relationship, satisfaction with consultation), most low-certainty evidence): across constructs there may be minimal or no effects of interventions to improve EoL communication, and there is uncertainty about effects of interventions such as a patient-specific feedback sheet on quality of communication.  Discussions of EoL or EoL care (six studies measuring selected outcomes, low- or very low-certainty evidence): a family conference intervention may increase duration of EoL discussions in an intensive care unit (ICU) setting, while use of a structured serious illness conversation guide may lead to earlier discussions of EoL and EoL care (each assessed by one study). We are uncertain about effects on occurrence of discussions and question asking in consultations, and there may be little or no effect on content of communication in consultations.  Adverse outcomes or unintended effects (limited evidence): there is insufficient evidence to determine whether there are adverse outcomes associated with communication interventions  (e.g. question prompt list, family conference, structured discussions) for EoL and EoL care. Patient and/or carer anxiety was reported by three studies, but judged as confounded. No other unintended consequences, or worsening of desired outcomes, were reported. Patient/carer quality of life (four studies, low-certainty evidence; two without useable data): interventions to improve communication may have little or no effect on quality of life.  Health practitioner outcomes (three studies, low-certainty evidence; two without usable data): interventions to improve communication may have little or no effect on health practitioner outcomes (satisfaction with communication during consultation; one study); effects on other outcomes (knowledge, preparedness to communicate) are unknown. Health systems impacts: communication interventions (e.g. structured EoL conversations) may have little or no effect on carer or clinician ratings of quality of EoL care (satisfaction with care, symptom management, comfort assessment, quality of care) (three studies, low-certainty evidence), or on patients' self-rated care and illness, or numbers of care goals met (one study, low-certainty evidence). Communication interventions (e.g. question prompt list alone or with nurse-led communication skills training) may slightly increase mean consultation length (two studies), but other health service impacts (e.g. hospital admissions) are unclear. AUTHORS' CONCLUSIONS: Findings of this review are inconclusive for practice. Future research might contribute meaningfully by seeking to fill gaps for populations not yet studied in trials; and to develop responsive outcome measures with which to better assess the effects of communication on the range of people involved in EoL communication episodes. Mixed methods and/or qualitative research may contribute usefully to better understand the complex interplay between different parties involved in communication, and to inform development of more effective interventions and appropriate outcome measures. Co-design of such interventions and outcomes, involving the full range of people affected by EoL communication and care, should be a key underpinning principle for future research in this area.

Non-signaling Chimeric Antigen Receptors Enhance Antigen-Directed Killing by γδ T Cells in Contrast to αß T Cells.

Chimeric antigen receptor (CAR)-modified T cells have demonstrated efficacy against B cell leukemias/lymphomas. However, redirecting CAR T cells to malignant T cells is more challenging due to product-specific cis- and trans-activation causing fratricide. Other challenges include the potential for product contamination and T cell aplasia. We expressed non-signaling CARs (NSCARs) in γδ T cells since donor-derived γδ T cells can be used to prevent product contamination, and NSCARs lack signaling/activation domains, but retain antigen-specific tumor cell-targeting capability. As a result, NSCAR targeting requires an alternative cytotoxic mechanism, which can be achieved through utilization of γδ T cells that possess major histocompatibility complex (MHC)-independent cytotoxicity. We designed two distinct NSCARs and demonstrated that they do not enhance tumor-killing by αß T cells, as predicted. However, both CD5-NSCAR- and CD19-NSCAR-modified γδ T cells enhanced cytotoxicity against T and B cell acute lymphoblastic leukemia (T-ALL and B-ALL) cell lines, respectively. CD5-NSCAR expression in γδ T cells resulted in a 60% increase in cytotoxicity of CD5-expressing T-ALL cell lines. CD19-NSCAR-modified γδ T cells exhibited a 350% increase in cytotoxicity against a CD19-expressing B-ALL cell line compared to the cytotoxicity of naive cells. NSCARs may provide a mechanism to enhance antigen-directed anti-tumor cytotoxicity of γδ T cells through the introduction of a high-affinity interaction while avoiding self-activation.

TGF-ß2 is an exercise-induced adipokine that regulates glucose and fatty acid metabolism.

Exercise improves health and well-being across diverse organ systems, and elucidating mechanisms underlying the beneficial effects of exercise can lead to new therapies. Here, we show that transforming growth factor-ß2 (TGF-ß2) is secreted from adipose tissue in response to exercise and improves glucose tolerance in mice. We identify TGF-ß2 as an exercise-induced adipokine in a gene expression analysis of human subcutaneous adipose tissue biopsies after exercise training. In mice, exercise training increases TGF-ß2 in scWAT, serum, and its secretion from fat explants. Transplanting scWAT from exercise-trained wild type mice, but not from adipose tissue-specific Tgfb2-/- mice, into sedentary mice improves glucose tolerance. TGF-ß2 treatment reverses the detrimental metabolic effects of high fat feeding in mice. Lactate, a metabolite released from muscle during exercise, stimulates TGF-ß2 expression in human adipocytes. Administration of the lactate-lowering agent dichloroacetate during exercise training in mice decreases circulating TGF-ß2 levels and reduces exercise-stimulated improvements in glucose tolerance. Thus, exercise training improves systemic metabolism through inter-organ communication with fat via a lactate-TGF-ß2-signaling cycle.

Voluntary wheel running promotes resilience to chronic social defeat stress in mice: a role for nucleus accumbens ΔFosB.

Elucidating mechanisms by which physical exercise promotes resilience, the brain's ability to cope with prolonged stress exposure while maintaining normal psychological functioning, is a major research challenge given the high prevalence of stress-related mental disorders, including major depressive disorder. Chronic voluntary wheel running (VWR), a rodent model that mimics aspects of human physical exercise, induces the transcription factor ΔFosB in the nucleus accumbens (NAc), a key reward-related brain area. ΔFosB expression in NAc modulates stress susceptibility. Here, we explored whether VWR induction of NAc ΔFosB promotes resilience to chronic social defeat stress (CSDS). Male young-adult C57BL/6J mice were single housed for up to 21 d with or without running wheels and then subjected to 10 d of CSDS. Stress-exposed sedentary mice developed a depressive-like state, characterized by anhedonia and social avoidance, whereas stress-exposed mice that had been wheel running showed resilience. Functional inhibition of NAc ΔFosB during VWR, by viral-mediated overexpression of a transcriptionally inactive JunD mutant, reinstated susceptibility to CSDS. Within the NAc, VWR induction of ΔFosB was CREB-dependent, associated with altered dendritic morphology, and medium spiny neuron (MSN) subtype specific in the NAc core and shell subregions. Finally, when mice performed VWR following the onset of CSDS-induced social avoidance, VWR normalized such behavior. These data indicate that VWR promoted resilience to CSDS, and suggest that sustained induction of ΔFosB in the NAc underlies, at least in part, the stress resilience mediated by VWR. These findings provide a potential framework for the development of treatments for stress-associated mental illnesses based on physical exercise.

Improving the experiences and health of people with multimorbidity: exploratory research with policymakers and information providers on comorbid arthritis.

Multimorbidity has emerged as a complex health issue with the burden falling predominantly on patients, families and the primary health care sector. Evidence-informed communication and participation, activities informed by evidence and people's views and experiences, has the potential to improve health outcomes for people with multimorbidity. In recognition of their role in shaping future actions, we conducted focus groups with policymakers and information providers. The aim of this article is to report on the range and impacts of communication problems in multimorbidity, and identify points of intervention. To facilitate and focus dialogue, comorbid arthritis was selected as the case example. Two focus groups were held: one with policymakers and the other with health information providers. Participants were asked to discuss communication problems and possibilities relevant to multimorbidity, using examples from comorbid arthritis where relevant. Participants highlighted three main areas on which to focus future efforts to improve the health outcomes and experiences of people with multimorbidity: (1) make explicit the problems of multimorbidity and communication; (2) recognise that both multimorbidity and communication issues are compounding factors; and (3) consider actions at policy, service, community and individual levels. Examining multimorbidity through the lens of communication issues identified the significant burden across different domains of the health system. The focus on communication may facilitate a cross-disease perspective to emerge and assist with policy development.

Building blocks for meta-synthesis: data integration tables for summarising, mapping, and synthesising evidence on interventions for communicating with health consumers.

BACKGROUND: Systematic reviews have developed into a powerful method for summarising and synthesising evidence. The rise in systematic reviews creates a methodological opportunity and associated challenges and this is seen in the development of overviews, or reviews of systematic reviews. One of these challenges is how to summarise evidence from systematic reviews of complex interventions for inclusion in an overview. Interventions for communicating with and involving consumers in their care are frequently complex. In this article we outline a method for preparing data integration tables to enable review-level synthesis of the evidence on interventions for communication and participation in health. METHODS AND RESULTS: Systematic reviews published by the Cochrane Consumers and Communication Review Group were utilised as the basis from which to develop linked steps for data extraction, evidence assessment and synthesis. The resulting output is called a data integration table. Four steps were undertaken in designing the data integration tables: first, relevant information for a comprehensive picture of the characteristics of the review was identified from each review, extracted and summarised. Second, results for the outcomes of the review were assessed and translated to standardised evidence statements. Third, outcomes and evidence statements were mapped into an outcome taxonomy that we developed, using language specific to the field of interventions for communication and participation. Fourth, the implications of the review were assessed after the mapping step clarified the level of evidence available for each intervention. CONCLUSION: The data integration tables represent building blocks for constructing overviews of review-level evidence and for the conduct of meta-synthesis. Individually, each table aims to improve the consistency of reporting on the features and effects of interventions for communication and participation; provides a broad assessment of the strength of evidence derived from different methods of analysis; indicates a degree of certainty with results; and reports outcomes and gaps in the evidence in a consistent and coherent way. In addition, individual tables can serve as a valuable tool for accurate dissemination of large amounts of complex information on communication and participation to professionals as well as to members of the public.
