RESUMO

The human pathogen Mycobacterium tuberculosis typically causes lung disease but can also disseminate to other tissues. We identified a M. tuberculosis (Mtb) outbreak presenting with unusually high rates of extrapulmonary dissemination and bone disease. We found that the causal strain carried an ancestral full-length version of the type VII-secreted effector EsxM rather than the truncated version present in other modern Mtb lineages. The ancestral EsxM variant exacerbated dissemination through enhancement of macrophage motility, increased egress of macrophages from established granulomas, and alterations in macrophage actin dynamics. Reconstitution of the ancestral version of EsxM in an attenuated modern strain of Mtb altered the migratory mode of infected macrophages, enhancing their motility. In a zebrafish model, full-length EsxM promoted bone disease. The presence of a derived nonsense variant in EsxM throughout the major Mtb lineages 2, 3, and 4 is consistent with a role for EsxM in regulating the extent of dissemination.

RESUMO

BACKGROUND: The Children's Palliative Outcome Scale (C-POS) is being developed using best methodological guidance on outcome measure development, This recommends cognitive testing, an established method of item improvement, prior to psychometric testing. AIM: To cognitively test C-POS within the target population to establish comprehensibility, comprehensiveness, relevance and acceptability. DESIGN: Cross-sectional cognitive interview study following COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) methodology and Rothrock guidance on outcome measure development. Cognitive interviews were conducted using 'think aloud' and verbal probing techniques. SETTING/PARTICIPANTS: Children 5-⩽17 years old with life-limiting conditions and parents/carers of children with life-limiting conditions were recruited from 14 UK sites. RESULTS: Forty-eight individuals participated (36 parents; 12 children) in cognitively testing the five versions of C-POS over two to seven rounds. Content and length were acceptable, and all questions were considered important. Refinements were made to parent/carer versions to be inclusive of non-verbal children such as changing 'share' to 'express' feelings; and 'being able to ask questions' to 'having the appropriate information'. Changes to improve comprehensibility of items such as 'living life to the fullest' were also made. Parents reported that completing an outcome measure can be distressing but this is anticipated and that being asked is important. CONCLUSION: Cognitive interviewing has facilitated refinement of the C-POS, especially for non-verbal children who represent a large proportion of those with a life-limiting condition. This study has enhanced the face and content validity of the measure and provided preliminary evidence for acceptability for use in routine practice.

RESUMO

BACKGROUND: Children and young people with life-limiting and life-threatening conditions have multidimensional needs and heterogenous cognitive and communicative abilities. There is limited evidence to support clinicians to tailor their communication to each individual child. AIM: To explore the language children and young people use to describe their own condition, to inform strategies for discussing needs and priorities. DESIGN: Positioned within a social constructivist paradigm, a secondary discourse analysis of semi-structured interview data was conducted incorporating the discourse dynamics approach for figurative language. SETTING/PARTICIPANTS: A total of 26 children and young people aged 5-17 years with life-limiting or life-threatening conditions (6 cancer; 20 non-cancer) were recruited from nine clinical services (six hospitals and three hospices) across two UK nations. RESULTS: The language children and young people use positions them as 'experts in their condition'. They combine medical terminology with their preferred terms for their body to describe symptoms and treatments, and use comparatives and superlatives to communicate their health status. Their language depicts their condition as a 'series of (functional and social) losses', which single them out from their peers as 'the sick one'. Older children and young people also incorporate figurative language to expand their descriptions. CONCLUSION/DISCUSSION: Children and young people can provide rich descriptions of their condition. Paying attention to their lexical choices, and converging one's language towards theirs, may enable more child-centred discussions. Expanding discussions about 'what matters most' with consideration of the losses and differences they have experienced may facilitate a fuller assessment of their concerns, preferences and priorities.

RESUMO

BACKGROUND: There is a growing evidence-base underpinning implementation of person-centred outcome measures into adult palliative care. However evidence on how best to achieve this with children facing life-threatening and life-limiting conditions is limited. AIM: To identify the anticipated benefits, risks, barriers and facilitators to implementing person-centred outcome measures for children with life-limiting and life-threatening conditions. DESIGN: Cross-sectional qualitative semi-structured interview study with key stakeholders analysed using Framework analysis informed by the adapted-Consolidated Framework for Implementation Research. SETTING/PARTICIPANTS: A total of n = 26 children with life-limiting or life-threatening conditions, n = 40 parents/carers, n = 13 siblings and n = 15 health and social care professionals recruited from six hospitals and three children's hospices and n = 12 Commissioners of health services. RESULTS: All participants were supportive of future implementation of person-centred outcome measures into care. Anticipated benefits included: better understanding of patient and family priorities, improved communication and collaborative working between professionals and families and standardisation in data collection and reporting. Anticipated risks included increased workload for staff and measures not being used as intended. Implementation barriers included: acceptability and usability of outcome measures by children; burden and capacity of parents/carers regarding completion; privacy concerns; and language barriers. Implementation facilitators included designing measures using language that is meaningful to children and families, ensuring potential benefits of person-centred outcome measures are communicated to encourage 'buy-in' and administering measures with known and trusted professional. CONCLUSIONS: Implementation of person-centred outcome measures offer potential benefits for children with life-limiting and life-threatening conditions. Eight recommendations are made to maximise benefits and minimise risks in implementation.

RESUMO

INTRODUCTION: Shared decision-making intends to align care provision with individuals' preferences. However, the involvement of people living with dementia in decision-making about their care varies. We aimed to co-design the EMBED-Care Framework, to enhance shared decision-making between people affected by dementia and practitioners. METHODS: A theory and evidence driven co-design study was conducted, using iterative workshops, informed by a theoretical model of shared decision-making and the EMBED-Care Framework (the intervention) for person-centred holistic palliative dementia care. The intervention incorporates a holistic outcome measure for assessment and review, linked with clinical decision-support tools to support shared decision-making. We drew on the Medical Research Council (MRC) guidance for developing and evaluating complex interventions. Participants included people with dementia of any type, current or bereaved family carers and practitioners. We recruited via established dementia groups and research and clinical networks. Data were analysed using reflexive thematic analysis to explore how and when the intervention could enhance communication and shared decision-making, and the requirements for use, presented as a logic model. RESULTS: Five co-design workshops were undertaken with participants comprising people affected by dementia (n = 18) and practitioners (n = 36). Three themes were generated, comprising: (1) 'knowing the person and personalisation of care', involving the person with dementia and/or family carer identifying the needs of the person using a holistic assessment. (2) 'engaging and considering the perspectives of all involved in decision-making' required listening to the person and the family to understand their priorities, and to manage multiple preferences. (3) 'Training and support activities' to use the Framework through use of animated videos to convey information, such as to understand the outcome measure used to assess symptoms. CONCLUSIONS: The intervention developed sought to enhance shared decision-making with individuals affected by dementia and practitioners, through increased shared knowledge of individual priorities and choices for care and treatment. The workshops generated understanding to manage disagreements in determining priorities. Practitioners require face-to-face training on the intervention, and on communication to manage sensitive conversations about symptoms, care and treatment with individuals and their family. The findings informed the construction of a logic model to illustrate how the intervention is intended to work.

RESUMO

BACKGROUND: Early language delay is exacerbated by social disadvantage. Factors such as parents' low levels of literacy, confidence and self-perception can affect the capacity to act on advice received, critical to empowerment. Methods used to achieve successful health outcomes in socially disadvantaged clinical populations may need enhancing. AIMS: To compare the impact of standard parent-based intervention (PBI) to enhanced PBI for young children with speech, language and communication needs (SCLN) and their families living in more socially disadvantaged populations. METHODS AND PROCEDURES: A multicentre clustered blind randomised controlled trial was used to compare the effect of parent-based group interventions to improve early language development with children (mean age 27.5 months) from more socially disadvantaged populations with an expressive vocabulary of 40 or less single words. Intervention sessions were delivered by a speech and language therapist, over a 20-week period. Participants received one of two interventions: (1) Standard Care - indirect group PBI - (PBI) (2) Enhanced Care: indirect group enhanced PBI - (EPBI). Both standardised and non-standardised measures were used as outcomes. Parent engagement in the intervention was captured through analysis of attendance and the Parent Activation Measure - Speech & Language Therapy (PAM-SLT) (Insignia Health, 2014). The PAM measures a person's knowledge, skills and confidence to manage their own health and well-being (NHS England, 2018). In this study, activation referred to parents' knowledge, skills and confidence to manage their child's language development. OUTCOMES AND RESULTS: One hundred fifty-five participants were randomised at baseline. Children in both groups made significant improvements in the outcome on MacArthur-Bates Communicative Development Inventories Sentence Length, from pre-intervention to post-intervention and 6 months post-intervention (p < 0.05). Changes in vocabulary and expressive language skills were more equivocal, showing wide variation in confidence intervals for both groups. Where parents attended at least one intervention session almost all effect sizes were in favour of the EPBI intervention. Parents' activation levels significantly increased for both groups (EPBI p < 0.001, PBI p = 0.003), with a moderate effect size in favour of EPBI (Hedges' G 0.37, confidence interval -0.02 to 0.76), although wide variation was found. CONCLUSIONS AND IMPLICATIONS: This trial provides some evidence of facilitating the language development of children with SLCN from more socially disadvantaged areas through supporting caregivers. However, we found variation in outcomes; some children made excellent progress, whilst others did not. Further exploration of parent engagement and its relationship to child language outcomes will be valuable to understanding more about mechanisms of change in interventions that involve parents. WHAT THIS PAPER ADDS: What is already known on the subject Speech, language and communication needs (SLCN) have a knock-on effect on emotional well-being, school readiness, literacy and school attainment, putting children at increased risk of long-term consequences such as poor literacy, mental health problems and unemployment. In disadvantaged areas, the prevalence of language difficulties is higher than elsewhere. Factors such as parents' low levels of literacy, confidence and self-perception can affect the capacity to act on advice received, critical to empowerment. What this paper adds to existing knowledge Children with SLCN from more socially disadvantaged areas can make improvements in their language development through parent intervention, although wide individual variation was found. There was some evidence that children achieve better outcomes with EPBI, which employed an interagency collaborative approach. Parent's engagement (activation levels) increased significantly over time with intervention, with the increase twice as big for EPBI. What are the potential or actual clinical implications of this work? This trial provides some evidence that it is possible to facilitate the language development of children from more socially disadvantaged areas through supporting their caregivers. Further research would be useful to determine whether increases in parent engagement are related to adherence to intervention and change in child outcomes.

RESUMO

AIM: To explore the views and preferences for advance care planning from the perspectives of residents, family members and healthcare professionals in long-term care facilities. DESIGN: A qualitative descriptive design. METHODS: We conducted semi-structured interviews with 12 residents of long-term care facilities, 10 family members and 14 healthcare professionals. Data were analysed using reflexive thematic analysis. The social ecological model was used to develop implementation recommendations. RESULTS: We constructed a conceptual model of barriers and facilitators to advance care planning in long-term care facilities, drawing upon four dominant themes from the qualitative analysis: (1) The absence of discourse on end-of-life care: a lack of cultural climate to talk about death, the unspoken agreement to avoid conversations about death, and poor awareness of palliative care may hinder advance care planning initiation; (2) Relational decision-making process is a dual factor affecting advance care planning engagement; (3) Low trust and 'unsafe' cultures: a lack of honest information sharing, risks of violating social expectations and damaging social relationships, and risks of legal consequences may hinder willingness to engage in advance care planning; (4) Meeting and respecting residents' psychosocial needs: these can be addressed by readiness assessment, initiating advance care planning in an informal and equal manner and involving social workers. CONCLUSION: Our findings show that residents' voices were not being heard. It is necessary to identify residents' spontaneous conversation triggers, articulate the value of advance care planning in light of the family's values and preferences, and respect residents' psychosocial needs to promote advance care planning in long-term care facilities. Advance care planning may alleviate the decision-making burden of offspring in nuclear families. IMPLICATIONS FOR CLINICAL PRACTICE: The evidence-based recommendations in this study will inform the implementation of context-specific advance care planning in Asia-Pacific regions. PATIENT AND PUBLIC CONTRIBUTION: Patients and caregivers contributed to the interview pilot and data collection.

RESUMO

Mycobacterium tuberculosis (Mtb), the causative agent of tuberculosis, is one of the oldest and most successful pathogens in the world. Diverse selective pressures encountered within host cells have directed the evolution of unique phenotypic traits, resulting in the remarkable evolutionary success of this largely obligate pathogen. Despite centuries of study, the genetic repertoire utilized by Mtb to drive virulence and host immune evasion remains to be fully understood. Various genetic approaches have been and continue to be developed to tackle the challenges of functional gene annotation and validation in an intractable organism such as Mtb. In vitro and ex vivo systems remain the primary approaches to generate and confirm hypotheses that drive a general understanding of mycobacteria biology. However, it remains of great importance to characterize genetic requirements for successful infection within a host system as in vitro and ex vivo studies fail to fully replicate the complex microenvironment experienced by Mtb. In this review, we evaluate the employment of the mycobacterial genetic toolkit to probe the host-pathogen interface by surveying the current state of mycobacterial genetic studies within host systems, with a major focus on the murine model. Specifically, we discuss the different ways that these tools have been utilized to examine various aspects of infection, including bacterial survival/virulence, bacterial evasion of host immunity, and development of novel antibacterial/vaccine strategies.

RESUMO

Mycobacterium tuberculosis (Mtb) is a bacterium that exclusively resides in human hosts and remains a dominant cause of morbidity and mortality among infectious diseases worldwide. Host protection against Mtb infection is dependent on the function of immunity-related GTPase clade M (IRGM) proteins. Polymorphisms in human IRGM associate with altered susceptibility to mycobacterial disease, and human IRGM promotes the delivery of Mtb into degradative autolysosomes. Among the three murine IRGM orthologs, Irgm1 has been singled out as essential for host protection during Mtb infections in cultured macrophages and in vivo. However, whether the paralogous murine Irgm genes, Irgm2 and Irgm3, play roles in host defense against Mtb or exhibit functional relationships with Irgm1 during Mtb infection remains undetermined. Here, we report that Irgm1-/- mice are indeed acutely susceptible to aerosol infection with Mtb, yet the additional deletion of the paralogous Irgm3 gene restores protective immunity to Mtb infections in Irgm1-deficient animals. Mice lacking all three Irgm genes (panIrgm-/-) are characterized by shifted lung cytokine profiles at 5 and 24 weeks postinfection, but control disease until the very late stages of the infection, when panIrgm-/- mice display increased mortality compared to wild-type mice. Collectively, our data demonstrate that disruptions in the balance between Irgm isoforms is more detrimental to the Mtb-infected host than total loss of Irgm-mediated host defense, a concept that also needs to be considered in the context of human Mtb susceptibility linked to IRGM polymorphisms.

RESUMO

Antiviral therapeutics are a front-line defense against virally induced diseases. Because viruses frequently mutate to escape direct inhibition of viral proteins, there is interest in targeting the host proteins that the virus must co-opt to complete its replication cycle. However, a detailed understanding of the interactions between the virus and the host cell is necessary in order to facilitate development of host-directed therapeutics. As a first step, we performed a genome-wide loss of function screen using the alphacoronavirus HCoV-229E to better define the interactions between coronaviruses and host factors. We report the identification and validation of an ER-resident host protein, TMEM41B, as an essential host factor for not only HCoV-229E but also genetically distinct coronaviruses including the pandemic betacoronavirus SARS-CoV-2. We show that the protein is required at an early, but post-receptor engagement, stage of the viral lifecycle. Further, mechanistic studies revealed that although the protein was not enriched at replication complexes, it likely contributes to viral replication complex formation via mobilization of cholesterol and other lipids to facilitate host membrane expansion and curvature. Continued study of TMEM41B and the development of approaches to prevent its function may lead to broad spectrum anti-coronavirus therapeutics.

RESUMO

BACKGROUND: Person-centred outcome measures (PCOMs) are commonly used in routine adult healthcare to measure and improve outcomes, but less attention has been paid to PCOMs in children's services. The aim of this systematic review is to identify and synthesise existing evidence of the determinants, strategies, and mechanisms that influence the implementation of PCOMs into paediatric healthcare practice. METHODS: The review was conducted and reported in accordance with PRISMA guidelines. Databased searched included CINAHL, Embase, Medline, and PsycInfo. Google scholar was also searched for grey literature on 25th March 2022. Studies were included if the setting was a children's healthcare service, investigating the implementation or use of an outcome measure or screening tool in healthcare practice, and reported outcomes relating to use of a measure. Data were tabulated and thematically analysed through deductive coding to the constructs of the adapted-Consolidated Framework for Implementation Research (CFIR). Results were presented as a narrative synthesis, and a logic model developed. RESULTS: We retained 69 studies, conducted across primary (n = 14), secondary (n = 13), tertiary (n = 37), and community (n = 8) healthcare settings, including both child self-report (n = 46) and parent-proxy (n = 47) measures. The most frequently reported barriers to measure implementation included staff lack of knowledge about how the measure may improve care and outcomes; the complexity of using and implementing the measure; and a lack of resources to support implementation and its continued use including funding and staff. The most frequently reported facilitators of implementation and continued use include educating and training staff and families on: how to implement and use the measure; the advantages of using PCOMs over current practice; and the benefit their use has on patient care and outcomes. The resulting logic model presents the mechanisms through which strategies can reduce the barriers to implementation and support the use of PCOMs in practice. CONCLUSIONS: These findings can be used to support the development of context-specific implementation plans through a combination of existing strategies. This will enable the implementation of PCOMs into routine paediatric healthcare practice to empower settings to better identify and improve child-centred outcomes.

RESUMO

BACKGROUND: Family members can support advance care planning conversations. However, how family involvement in advance care planning operates to achieve goal-concordant care remains unclear. AIM: To explore how family involvement impacts the process of advance care planning for advanced cancer patients and their family members to achieve goal-concordant care in Japan. DESIGN: Qualitative study incorporating semi-structured in-depth interviews with thematic analysis informed by Family Systems Theory. SETTING/PARTICIPANTS: Medical oncology departments at two tertiary hospitals in Japan. A purposive sample of 13 advanced cancer patients, 10 family members and 9 healthcare professionals who cared for them. RESULTS: Twenty-five interviews were conducted, comprising 7 dyads of patients and their family members and 18 individual interviews. Four themes were identified: characteristics of patients and family members and their views on illness and advance care planning; family context and communication; interactions with healthcare professionals and societal and cultural influences; and family members' acceptance, preparation and confidence. Family involvement was observed as being variable at an individual level and also across generations. Family members provided patients with the instrumental and emotional support that facilitated the advance care planning process. Family involvement enabled family members to better prepare for realising patients' wishes. It increased family members' confidence in surrogate decision-making. CONCLUSIONS: Two mechanisms of how family involvement may enable goal-concordant care were identified: family members' support provision and their preparation for realising patients' wishes. Healthcare professionals should assess family's readiness to engage in advance care planning, and the time required to prepare them for the process.

RESUMO

BACKGROUND: Despite being a core domain of palliative care, primary data on spiritual and existential concerns has rarely been collected among children with life-limiting and life-threatening conditions and their families. Existing evidence has tended to focus on the religious aspects among children with cancer. AIM: To identify the spiritual needs of children with life-limiting and life-threatening conditions. DESIGN: Cross-sectional semi-structured, qualitative interview study with children, families and health and social care professionals. Verbatim transcripts were analysed using Framework analysis. SETTING/PARTICIPANTS: Purposively sampled children with life-limiting and life-threatening conditions, their parents and siblings, health and social care professionals recruited from six hospitals and three children's hospices in the UK, and commissioners of paediatric palliative care services recruited through networks and a national charity. RESULTS: One hundred six participants were interviewed: 26 children (5-17 years), 53 family members (parents/carers of children 0-17 years and siblings (5-17 years)), 27 professionals (health and social care professionals and commissioners of paediatric palliative care). Themes included: living life to the fullest, meaning of life and leaving a legacy, uncertainty about the future, determination to survive, accepting or fighting the future and role of religion. Children as young as 5 years old identified needs or concerns in the spiritual domain of care. CONCLUSIONS: Addressing spiritual concerns is essential to providing child- and family-centred palliative care. Eliciting spiritual concerns may enable health and social care professionals to identify the things that can support and enhance a meaningful life and legacy for children and their families.

RESUMO

BACKGROUND: There is no validated outcome measure for use in children's palliative care outside sub-Saharan Africa. Stakeholders must be involved in the development of such measures to ensure face and content validity. AIM: To gain expert stakeholder consensus on items for inclusion in a paediatric palliative care outcome measure to establish face and content validity. DESIGN: This study was conducted in two phases following Rothrock and COSMIN guidance on patient-reported outcome measure development. Phase 1: Three-round modified Delphi survey to establish consensus on priority items. Phase 2: Item generation meeting with key stakeholders to develop initial measure versions. A young person's advisory group was also consulted on priority outcomes. SETTING AND PARTICIPANTS: Delphi survey: Parents and professionals with experience of caring for a child with a life-limiting condition. Young person's advisory group: young people age 10-20 years. Item generation meeting: bereaved parents, academics and clinicians. RESULTS: Phase 1: Delphi survey (n = 82). Agreement increased from Kendall's W = 0.17 to W = 0.61, indicating movement towards consensus. Agreement between professional and parent ranking was poor (Cohen's kappa 0.13). Professionals prioritised physical symptoms, whereas parents prioritised psychosocial and practical concerns. Advisory group: Children (n = 22) prioritised items related to living a 'normal life' in addition to items prioritised by adult participants. Phase 2: Five age/developmental stage appropriate child and proxy-reported versions of C-POS, containing 13 items, were drafted. CONCLUSIONS: This study highlights the importance and feasibility of involving key stakeholders in PROM item generation, as important differences were found in the priority outcomes identified by children, parents and professionals.

RESUMO

Cell-intrinsic immune mechanisms control intracellular pathogens that infect eukaryotes. The intracellular pathogen Mycobacterium tuberculosis (Mtb) evolved to withstand cell-autonomous immunity to cause persistent infections and disease. A potent inducer of cell-autonomous immunity is the lymphocyte-derived cytokine IFNγ. While the production of IFNγ by T cells is essential to protect against Mtb, it is not capable of fully eradicating Mtb infection. This suggests that Mtb evades a subset of IFNγ-mediated antimicrobial responses, yet what mechanisms Mtb resists remains unclear. The IFNγ-inducible Guanylate binding proteins (GBPs) are key host defense proteins able to control infections with intracellular pathogens. GBPs were previously shown to directly restrict Mycobacterium bovis BCG yet their role during Mtb infection has remained unknown. Here, we examine the importance of a cluster of five GBPs on mouse chromosome 3 in controlling Mycobacterial infection. While M. bovis BCG is directly restricted by GBPs, we find that the GBPs on chromosome 3 do not contribute to the control of Mtb replication or the associated host response to infection. The differential effects of GBPs during Mtb versus M. bovis BCG infection is at least partially explained by the absence of the ESX1 secretion system from M. bovis BCG, since Mtb mutants lacking the ESX1 secretion system become similarly susceptible to GBP-mediated immune defense. Therefore, this specific genetic interaction between the murine host and Mycobacteria reveals a novel function for the ESX1 virulence system in the evasion of GBP-mediated immunity.

RESUMO

This study aims to identify the symptoms, concerns, and care priorities of children with life-limiting conditions and their families. A semi-structured qualitative interview study was conducted, seeking perspectives from multiple stakeholders on symptoms, other concerns, and care priorities of children and young people with life limiting and life-threatening conditions and their families. Participants were recruited from six hospitals and three children's hospices in the UK. Verbatim transcripts were analysed using framework analysis. A total of 106 participants were recruited: 26 children (5-17 years), 40 parents (of children 0-17 years), 13 siblings (5-17 years), 15 health and social care professionals, 12 commissioners. Participants described many inter-related symptoms, concerns, and care priorities impacting on all aspects of life. Burdensome symptoms included pain and seizures. Participants spoke of the emotional and social impacts of living with life-limiting conditions, such as being able to see friends, and accessing education and psychological support. Spiritual/existential concerns included the meaning of illness and planning for an uncertain future. Data revealed an overarching theme of pursuing 'normality', described as children's desire to undertake usual childhood activities. Parents need support with practical aspects of care to help realise this desire for normality. CONCLUSION: Children with life-limiting conditions and their families experience a wide range of inter-related symptoms, concerns, and care priorities. A holistic, child-centred approach to care is needed, allowing focus on pursuit of normal childhood activities. Improvements in accessibility, co-ordination, and availability of health services are required to achieve this. WHAT IS KNOWN: • Existing evidence regarding symptoms, concerns, and care priorities for children with life-limiting conditions is largely limited to proxy-reported data and those with a cancer diagnosis. • Child-centred care provision must be directed by children's perspectives on their priorities for care. WHAT IS NEW: • Social and educational activities are more important to children with life-limiting conditions than their medical concerns. • A holistic approach to care is required that extends beyond addressing medical needs, in order to support children with life-limiting conditions to focus on pursuit of normal childhood activities.

RESUMO

BACKGROUND: Advance care planning is important for people with advanced cancer. Family involvement in advance care planning may be instrumental to achieving goal-concordant care since they frequently become surrogate decision-makers. AIM: To examine components, contexts, effects and linkages with intended outcomes of involving family members in advance care planning. DESIGN: A mixed-methods systematic review, in which quantitative and qualitative data were extracted and synthesised using thematic synthesis leading to a logic model. Prospectively registered on PROSPERO (CRD42020208143). DATA SOURCES: Primary quantitative and qualitative research regarding family-involved advance care planning for people with advanced cancer were identified using Medline, Embase, PsycINFO and CINAHL from inception to September 2020. Quality appraisal was performed with 'QualSyst'. RESULTS: Fourteen articles were included. The synthesis identified perceptions of individuals and family members concerning family involvement in advance care planning and presents components for family-integrated advance care planning intervention. The logic model includes (i) addressing family members' concerns and emotions and (ii) facilitating communication between individuals and family members which are distinctive when healthcare professionals engage with individuals as well as family members. CONCLUSIONS: This review provides a comprehensive understanding of family involvement in advance care planning and could inform its assessment and implementation in clinical practice. The number of included articles was limited. Therefore future research must focus on family integration and exploration of stakeholders' perceptions to identify additional components and linkages between them within family-integrated advance care planning.

RESUMO

PURPOSE: Cystic fibrosis (CF), caused by pathogenic variants in the CF transmembrane conductance regulator (CFTR), affects multiple organs including the exocrine pancreas, which is a causal contributor to cystic fibrosis-related diabetes (CFRD). Untreated CFRD causes increased CF-related mortality whereas early detection can improve outcomes. METHODS: Using genetic and easily accessible clinical measures available at birth, we constructed a CFRD prediction model using the Canadian CF Gene Modifier Study (CGS; n = 1,958) and validated it in the French CF Gene Modifier Study (FGMS; n = 1,003). We investigated genetic variants shown to associate with CF disease severity across multiple organs in genome-wide association studies. RESULTS: The strongest predictors included sex, CFTR severity score, and several genetic variants including one annotated to PRSS1, which encodes cationic trypsinogen. The final model defined in the CGS shows excellent agreement when validated on the FGMS, and the risk classifier shows slightly better performance at predicting CFRD risk later in life in both studies. CONCLUSION: We demonstrated clinical utility by comparing CFRD prevalence rates between the top 10% of individuals with the highest risk and the bottom 10% with the lowest risk. A web-based application was developed to provide practitioners with patient-specific CFRD risk to guide CFRD monitoring and treatment.

RESUMO

BACKGROUND: Dementia is a life-limiting disease with high symptom burden. The Integrated Palliative Care Outcome Scale for Dementia (IPOS-Dem) is the first comprehensive person-centered measure to identify and measure palliative care needs of people with dementia. However, such a measure is missing in the German health care system. AIM: To develop a culturally adapted German version of the IPOS-Dem and determine its content validity as a foundation for comprehensive psychometric testing. DESIGN: Cognitive interview study with intermittent analysis and questionnaire adaptation. Interview guide and coding frame followed thematic analysis according to Willis complemented by Tourangeau's model of cognitive aspects of survey methodology: comprehension, retrieval, judgment, response. PARTICIPANTS: Purposive sample with professionals (n = 29) and family carers (n = 6) of people with advanced dementia in seven nursing homes and person's own home care in four interview rounds (n = 11; 10; 7; 7). RESULTS: IPOS-Dem was regarded as comprehensive and accessible. Cultural adaption pertained to issues of comprehension and judgment. Comprehension challenges referred to the person-centered concept of "being affected by" used in the POS-measures. Judgment problems related to persons with limited communication causing challenges in assessment. CONCLUSION: Most issues of cultural adaptation could be addressed by questionnaire modifications. However, interviews unveiled fundamental challenges for using proxy reported person-centered assessments. Continuous training on how to use the instrument is imperative to integrate the person-centered approach of palliative care into nursing homes as a key provider of generalist palliative care for people with dementia. The refined version is ready for psychometric testing.

RESUMO

OBJECTIVES: To explore enteral feeding practices and the achievement of energy targets in children on noninvasive respiratory support, in four European PICUs. DESIGN: A four-center retrospective cohort study. SETTING: Four PICUs: Bristol, United Kingdom; Lyon, France; Madrid, Spain; and Rotterdam, The Netherlands. PATIENTS: Children in PICU who required acute noninvasive respiratory support in the first 7 days. The primary outcome was achievement of standardized kcal/goal. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: A total of 325 children were included (Bristol 104; Lyon 99; Madrid 72; and Rotterdam 50). The median (interquartile range) age and weight were 3 months (1-16 mo) and 5 kg (4-10 mo), respectively, with 66% admitted with respiratory failure. There were large between-center variations in practices. Overall, 190/325 (58.5%) received noninvasive respiratory support in order to prevent intubation and 41.5% after extubation. The main modes of noninvasive respiratory support used were high-flow nasal cannula 43.6%, bilevel positive airway pressure 33.2%, and continuous positive airway pressure 21.2%. Most children (77.8%) were fed gastrically (48.4% continuously) and the median time to the first feed after noninvasive respiratory support initiation was 4 hours (interquartile range, 1-9 hr). The median percentage of time a child was nil per oral while on noninvasive respiratory support was 4 hours (2-13 hr). Overall, children received a median of 56% (25-82%) of their energy goals compared with a standardized target of 0.85 of the recommended dietary allowance. Patients receiving step-up noninvasive respiratory support (p = < 0.001), those on bilevel positive airway pressure or continuous positive airway pressure (compared with high-flow nasal cannula) (p = < 0.001), and those on continuous feeds (p = < 0.001) achieved significantly more of their kcal goal. Gastrointestinal complications varied from 4.8-20%, with the most common reported being vomiting in 54/325 (16.6%), other complications occurred in 40/325 (12.3%) children, but pulmonary aspiration was rare 5/325 (1.5%). CONCLUSIONS: Children on noninvasive respiratory support tolerated feeding well, with relatively few complications, but prospective trials are now required to determine the optimal timing and feeding method for these children.
