This study explored healthcare professionals' perceived role in talking to adult patients about sharing their diagnosis with children. Semi-structured interviews were conducted to explore healthcare professionals' beliefs about how families could and should be supported when a parent has a serious illness. Participants were 24 healthcare professionals working in primary, secondary and tertiary NHS services in the UK with adult patients diagnosed with a serious illness. Data were analysed thematically. Many healthcare professionals reported systems to identify patients' family relationships, but this information was rarely used to initiate conversations on what and how to talk to children. It was frequently assumed that someone else in the healthcare system was supporting patients with family communication. Others reported there were more urgent priorities for the consultation or considered that talking to children was a private family matter. However, several professionals did undertake these conversations, viewing this as a central part of their role. Some healthcare professionals felt they had inadequate skills or confidence to raise talking to children with their patients and indicated a need for specific training to address this. The results highlight the importance of systematically documenting patients' relationships with children so that this information can be used to inform ongoing discussions with the healthcare team about what children have been told. Patients consistently report wanting support about how to talk to children and the benefits of effective communication are well documented. Dissemination of this evidence could encourage professionals across all specialities to include family-centred communication in routine patient care. Training resources are needed so that staff feel empowered and equipped to raise these sensitive subjects with their patients. [Abstract copyright: Copyright: © 2022 Dalton et al.

Background: Meeting the needs of relatives when a family member is dying can help facilitate better psychological adjustment in their grief. However, end of life experiences for families are likely to have been deleteriously impacted by the COVID-19 crisis. Understanding how families’ needs can be met during a global pandemic will have current/future relevance for clinical practice and policy. Aim: To explore relatives’ experiences and needs when a family member was dying during the COVID-19 pandemic. Design: Interpretative qualitative study using semi-structured interviews. Data were analysed thematically. Setting/participants: A total of 19 relatives whose family member died during the COVID-19 pandemic in the United Kingdom. Results: In the absence of direct physical contact, it was important for families to have a clear understanding of their family member’s condition and declining health, stay connected with them in the final weeks/days of life and have the opportunity for a final contact before they died. Health and social care professionals were instrumental to providing these aspects of care, but faced practical challenges in achieving these. Results are presented within three themes: (1) entering into the final weeks and days of life during a pandemic, (2) navigating the final weeks of life during a pandemic and (3) the importance of ‘saying goodbye’ in a pandemic. Conclusions: Health and social care professionals can have an important role in mitigating the absence of relatives’ visits at end of life during a pandemic. Strategies include prioritising virtual connectedness and creating alternative opportunities for relatives to ‘say goodbye’.

Young parents (aged 16–24 years) in the perinatal period are at an increased risk of poor mental health especially during the COVID-19 pandemic, due to multiple risk factors including social and economic instability. COVID-19 related restrictions had profound implications for the delivery of perinatal care services and other support structures for young parents. Investigating young parents’ experiences during the pandemic, including their perceived challenges and needs, is important to inform good practice and provide appropriate support for young parents.Qualitative interviews were conducted with young parents (n = 21) during the COVID-19 pandemic in the United Kingdom from February – May 2021. Data were analysed using thematic analysis.Three key themes were identified to describe parents’ experiences during the COVID-19 pandemic. Parents reported specific COVID-19 related anxieties and stressors, including worries around contracting the virus and increased feelings of distress due to uncertainty created by the implications of the pandemic. Parents described feeling alone both at home and during antenatal appointments and highlighted the absence of social support as a major area of concern. Parents also felt their perinatal care had been disrupted by the pandemic and experienced difficulties accessing care online or over the phone.This study highlights the potential impact of the COVID-19 pandemic on young parents, including their mental wellbeing and the perinatal support they were able to access. Insights from this study can inform the support and services offered to families going forward. Specifically, the findings emphasise the importance of (a) supporting both parents during perinatal appointments, (b) providing parents with mental health support early on and (c) finding ways to facilitate communication pathways between professionals and parents.

ObjectivesThis study aimed to explore how published communication frameworks could be amended to ensure applicability and cultural appropriateness for professionals to support family-centred conversations by investigating’ healthcare professionals’ (1) experiences of providing support to families when a caregiver or a dependent child (DesignA qualitative study involving two 2-day workshops with embedded focus group discussions, break out rooms and consensus discussions.SettingHealth and social care and third sector organisations in South Africa and Uganda.ParticipantsThirty-two professionals providing care to families affected by life-threatening conditions in South Africa or Uganda who were aged 18 years or older and able to converse in English.ResultsParticipants identified obstacles to having conversations with caregivers about children and to telling children about serious illness during consultations. These included patients’ beliefs about illness, medicine and death, language barriers between families and the healthcare team, and emotional and practical challenges for professionals in having these conversations. Culturally appropriate adaptations were made to previously published communication frameworks for professionals to support family-centred conversations.ConclusionsCulturally sensitive communication frameworks could help healthcare professionals to talk with families about what children need to know when they or a caregiver have a serious illness. More broadly, effective communication could be facilitated by promoting healthcare professionals’ and communities’ understanding of the benefits of telling children about illness within the family. Together these strategies may mitigate the psychological impact of global disease on children and their families.

Purpose: Health and social care professionals report it challenging to have conversations with families when an important adult in the life of a child is at end of life, often feeling this aspect of care is the responsibility of other colleagues. This study aimed to understand professionals’ perceived role in family-centered conversations as part of routine care at end of life, and how to promote this element of care in clinical practice. Methods: An audit was completed with 116 professionals who work in palliative care including doctors and nurses that attended a 2-day virtual congress. Results: Professionals (73.2%) felt confident about starting a conversation with adult patients at end of life about important children. However, enquiring about relationships with children was largely dependent on the age of the patient. 64.7% of respondents reported signposting families to websites and services that provide family support. Most professionals (76.7%) wanted training to equip them with the skills and confidence to having family-centered conversations at end of life, with videos demonstrating how to provide these elements of care the most preferred option. Conclusions: Short training resources should be developed to equip professionals with the necessary skills toward having conversations about children with patients and relatives in clinical appointments. There is a need for professionals to ask every patient about important relationships with children.

ObjectivesA key barrier in supporting health research capacity development (HRCD) is the lack of empirical measurement of competencies to assess skills and identify gaps in research activities. An effective tool to measure HRCD in healthcare workers would help inform teams to undertake more locally led research. The objective of this systematic review is to identify tools measuring healthcare workers’ individual capacities to conduct research.DesignSystematic review and narrative synthesis using Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist for reporting systematic reviews and narrative synthesis and the Critical Appraisals Skills Programme (CASP) checklist for qualitative studies.Data sources11 databases were searched from inception to 16 January 2020. The first 10 pages of Google Scholar results were also screened.Eligibility criteriaWe included papers describing the use of tools/to measure/assess HRCD at an individual level among healthcare workers involved in research. Qualitative, mixed and quantitative methods were all eligible. Search was limited to English language only.Data extraction and synthesisTwo authors independently screened and reviewed studies using Covidence software, and performed quality assessments using the extraction log validated against the CASP qualitative checklist. The content method was used to define a narrative synthesis.ResultsThe titles and abstracts for 7474 unique records were screened and the full texts of 178 references were reviewed. 16 papers were selected: 7 quantitative studies; 1 qualitative study; 5 mixed methods studies; and 3 studies describing the creation of a tool. Tools with different levels of accuracy in measuring HRCD in healthcare workers at the individual level were described. The Research Capacity and Culture tool and the ‘Research Spider’ tool were the most commonly defined. Other tools designed for ad hoc interventions with good generalisability potential were identified. Three papers described health research core competency frameworks. All tools measured HRCD in healthcare workers at an individual level with the majority adding a measurement at the team/organisational level, or data about perceived barriers and motivators for conducting health research.ConclusionsCapacity building is commonly identified with pre/postintervention evaluations without using a specific tool. This shows the need for a clear distinction between measuring the outcomes of training activities in a team/organisation, and effective actions promoting HRCD. This review highlights the lack of globally applicable comprehensive tools to provide comparable, standardised and consistent measurements of research competencies.PROSPERO registration numberCRD42019122310.

Background: COVID-19 public health restrictions have affected end-of-life care experiences for dying patients and their families. Aim: To explore bereaved relatives’ experiences of quality of care and family support provided during the last days of life; to identify the impact of factors associated with perceived support. Design: A national, observational, open online survey was developed and disseminated via social media, public fora and professional networks (June–September 2020). Validated instruments and purposively designed questions assessed experiences. Analysis used descriptive statistics, logistic regression and thematic analysis of free-text responses. Participants: Individuals (⩾18 years) who had experienced the death of a relative/friend (all care settings) within the United Kingdome during the COVID-19 pandemic. Results: Respondents ( n = 278, mean 53.4 years) tended to be female ( n = 216, 78%); over half were ‘son/daughter’ (174, 62.6%) to the deceased. Deceased individuals (mean 81.6 years) most frequently died in their ‘usual place of care’ ( n = 192, 69.3%). Analysis established five conceptual themes affecting individualised care: (1) public health restrictions compounding the distress of ‘not knowing’; (2) disparate views about support from doctors and nurses; (3) challenges in communication and level of preparedness for the death; (4) delivery of compassionate care; (5) emotional needs and potential impact on grief. Male respondents (OR 2.9, p = 0.03) and those able to visit (OR 2.2, p = 0.04) were independently associated with good perceptions of family support. Conclusion: Despite public health restrictions, individualised care can be enabled by proactive, informative communication; recognising dying in a timely manner and facilitating the ability to be present before death.

Background: Health and social care professionals’ ability to address the needs of patients and their relatives at end of life is likely to have been impacted by the COVID-19 pandemic. Aim: To explore health and social care professionals’ experiences of providing end of life care during the COVID-19 pandemic to help inform current/future clinical practice and policy. Design: A qualitative interview study. Data were analysed using thematic analysis. Setting/participants: Sixteen health and social care professionals working across a range of clinical settings in supporting dying patients during the first wave (March–June 2020) of the COVID-19 pandemic in the United Kingdom. Results: Participants reported emotional and practical challenges to providing end of life care during the pandemic, including increases in patient numbers, reduced staffing levels and relying on virtual platforms for sensitive, emotive conversations with relatives. Participants were central to promoting connections between patients and their families at end of life and creating opportunities for a final contact before the death. However, the provision of support varied as a consequence of the pressures of the pandemic. Results are discussed under two themes: (1) challenges and facilitators to providing end of life care, and (2) support needs of relatives when a family member was dying during the COVID-19 pandemic. Conclusion: There is a need for flexible visiting arrangements at end of life during a pandemic. A systems-level approach is necessary to promote the wellbeing of health and social care professionals providing end of life care during and after a pandemic.

Background The COVID-19 pandemic significantly affected experiences of death and dying for patients and families. Our focus was on bereaved relatives’ perceptions about experiences of care in the last days of life during the pandemic to help inform practice and policy. Methods A national online survey, informed by patient and public involvement, was developed and disseminated via social media, public and professional networks between June and October 2020. Validated instruments (e.g. abbreviated ‘Care Of the Dying Evaluation’ questionnaire) and purposively designed questions were used to assess the impact of COVID-19. Data was analysed using descriptive statistics, logistic regression and thematic analysis of free-text responses. Results Respondents (n=278) had a mean age of 53.4 years (range 19–68); 216 (78.0%) female and 174 (62.6%) ‘son/daughter’ to the deceased. Over half (156, 56.5%) were unable to visit during the dying phase. Almost 70% of the deceased (mean age 80.5 years; 160 (57.6%) female) died in their ‘usual place of care’ (home n=30 (10.8%); nursing home n=162 (58.3%)). This was perceived as the ‘right place’ by 176 (75.2%) respondents. Positive perceptions were reported about nursing care compared with medical care. Unmet support was reported: 71 (30.1%) rated emotional support as ‘poor’; 110 (45.5%) perceived they were inadequately supported prior to death. Being a male respondent (OR 2.9, p=0.03) and able to visit during the last days of life (OR 2.2, p=0.04) were independently associated with perceptions about being adequately supported. Corresponding free-text analysis suggested ‘not knowing’ about care was especially distressful; ‘clear, compassionate leadership’ contributed to positive experiences. Conclusions Capturing these experiences during the height of the first COVID-19 wave is pertinent to inform measures to enhance care. Disconnection between dying patients and families is a key area to be addressed and the challenge of balancing individual and societal needs to enable high quality end-of-life care.

Many adults diagnosed with a life-threatening condition have children living at home; they and their partners face the dual challenge of coping with the diagnosis while trying to maintain a parenting role. Parents are often uncertain about how, when, and what to tell their children about the condition, and are fearful of the effect on their family. There is evidence that children are often aware that something is seriously wrong and want honest information. Health-care professionals have a key role in supporting and guiding parents and caregivers to communicate with their children about the diagnosis. However, the practical and emotional challenges of communicating with families are compounded by a scarcity of evidence-based guidelines. This Review considers children's awareness and understanding of their parents' condition, the effect of communication around parental life-threatening condition on their wellbeing, factors that influence communication, and the challenges to achieving effective communication. Children's and parents' preferences about communication are outlined. An expert workshop was convened to generate principles for health-care professionals, intended as practical guidance in the current absence of empirically derived guidelines.

When a child is diagnosed with a life-threatening condition, one of the most challenging tasks facing health-care professionals is how to communicate this to the child, and to their parents or caregivers. Evidence-based guidelines are urgently needed for all health-care settings, from tertiary referral centres in high-income countries to resource limited environments in low-income and middle-income countries, where rates of child mortality are high. We place this Review in the context of children's developing understanding of illness and death. We review the effect of communication on children's emotional, behavioural, and social functioning, as well as treatment adherence, disease progression, and wider family relationships. We consider the factors that influence the process of communication and the preferences of children, families, and health-care professionals about how to convey the diagnosis. Critically, the barriers and challenges to effective communication are explored. Finally, we outline principles for communicating with children, parents, and caregivers, generated from a workshop of international experts.

BackgroundMaternal postnatal depression occurs following 10–15% of births and is associated with a range of negative child outcomes. Risks to children are particularly increased when postnatal depression is persistent. We aimed to examine whether a parenting video-feedback therapy (VFT) intervention versus a control treatment of progressive muscle relaxation (PMR), both added to cognitive behavioural therapy (CBT) for persistent postnatal depression, would lead to improved child outcomes at age 2 years.MethodsIn this two-arm, parallel-design, individually randomised controlled trial, we recruited a community sample of women aged 18 years or older living within 50 miles of Oxford, UK, between 4·5 and 9·0 months post partum. All participants met diagnostic criteria for current major depressive disorder that had persisted for at least 3 months and had infants at 35 or more weeks of gestation, with a birthweight of 2000 g or greater, and without serious neonatal complications. Through a centralised service, women were randomly assigned by use of a minimisation algorithm, to receive either VFT or PMR, balanced for child sex, temperament, age, socioeconomic status, and severity of depression. Both groups also received CBT for depression. Primary outcomes were child cognitive development, language development, behaviour problems, and attachment security at age 2 years. There were 11 home-based treatment sessions before child age 1 year, followed by two booster sessions in the second year. Assessors were masked to treatment group allocation. All analyses were done according to the intention-to-treat principle. This trial is registered with the ISRCTN registry, number ISRCTN07336477.FindingsBetween March 18, 2011, and Dec 9, 2013, we randomly assigned 144 women, 72 to each group. Primary outcome data were available for 62–64 (86–89%) VFT and 67–68 (93–94%) PMR participants. There were no group differences in child outcome (cognitive development, adjusted difference −1·01 [95% CI −5·11 to 3·09], p=0·63; language development, 1·33 [–4·16 to 6·82], p=0·63; behaviour problems, −1·77 [–4·39 to 0·85], p=0·19; attachment security, 0·02 [–0·06 to 0·10], p=0·58), with both groups achieving scores similar to non-clinical norms on all outcomes. There were six serious adverse events: five in the VFT group (in two participants) and one in the PMR group. None was treatment-related.InterpretationThe effect of persistent postnatal depression on children is a major public health issue. For both treatment groups there was sustained remission from depression, and child development outcomes were in the normal range. The precise mechanisms accounting for the observed positive child outcomes cannot be ascertained from this study.

Effective fetal growth requires adequate maternal nutrition coupled to active transport of nutrients across the placenta, which, in turn requires ATP. Epidemiological and experimental evidence has shown that impaired maternal nutrition in utero results in an adverse postnatal phenotype for the offspring. Placental mitochondrial function might link maternal food intake to fetal growth since impaired placental ATP production, in response to poor maternal nutrition, could be a pathway linking maternal food intake to reduced fetal growth.We assessed the effects of maternal diet on placental water content, ATP levels and mitochondrial DNA (mtDNA) content in mice at embryonic (E) day 18 (E18). Females maintained on either low- (LPD) or normal- (NPD) protein diets were mated with NPD males.Fetal dry weight and placental efficiency (embryo/placental fresh weight) were positively correlated (r = 0.53, P = 0.0001). Individual placental dry weight was reduced by LPD (P = 0.003), as was the expression of amino acid transporter Slc38a2 and of growth factor Igf2. Placental water content, which is regulated by active transport of solutes, was increased by LPD (P = 0.0001). However, placental ATP content was also increased (P = 0.03). To investigate the possibility of an underlying mitochondrial stress response, we studied cultured human trophoblast cells (BeWos). High throughput imaging showed that amino acid starvation induces changes in mitochondrial morphology that suggest stress-induced mitochondrial hyperfusion. This is a defensive response, believed to increase mitochondrial efficiency, that could underlie the increase in ATP observed in placenta.These findings reinforce the pathophysiological links between maternal diet and conceptus mitochondria, potentially contributing to metabolic programming. The quiet embryo hypothesis proposes that pre-implantation embryo survival is best served by a relatively low level of metabolism. This may extend to post-implantation trophoblast responses to nutrition.

BackgroundHealth researchers need a free, online and reliable mechanism to record their skill set, track their career development, and identify gaps in their knowledge. Research teams also require ways to monitor and report their team’s capacity development over time. The Global Health Network, a trusted and respected digital platform, is now able to provide researchers with these tools (www.globalhealthtrainingcentre.org/pds).MethodsThe Global Health Network compared diverse data types and took into account user feedback to create a professional development scheme (PDS). Together with TDR (The Special Programme for Research and Training in Tropical Diseases), a framework was developed with a list of the core competencies that a research team needs to demonstrate to carry out a study succesfully. A multi-functional dashboard was designed for team coordinators to assess the capacity development of individuals and groups.ResultsThe PDS provides researchers with a step by step process for recording their career and core competencies. The core competency framework can be applied to any research study, regardless of size of the team, place, disease focus or type of research. Team coordinators can quickly and easily produce visual records of the strengths and weaknesses in the competencies of their team and implement plans to address these gaps. Together with supporting tools in the PDS, research teams can plan staffing requirements for a study, carry out appraisals and guide the career development and training programme of research staff.ConclusionThe Global Health Network has created a flexible method and set of tools (PDS) to support researchers and teams to document their professional career and core competencies. It enables individuals and groups to easily identify and track capacity development; an essential requirement for conducting effective health research.

The immediate and short-term consequences of adult HIV for affected children are well documented. Little research has examined the long-term implications of childhood adversity stemming from caregiver HIV infection. Through overviews provided by experts in the field, together with an iterative process of consultation and refinement, we have extracted insights from the broader field of child development of relevance to predicting the long-term consequences to children affected by HIV and AIDS. We focus on what is known about the impact of adversities similar to those experienced by HIV-affected children, and for which there is longitudinal evidence. Cautioning that findings are not directly transferable across children or contexts, we examine findings from the study of parental death, divorce, poor parental mental health, institutionalization, undernutrition, and exposure to violence. Regardless of the type of adversity, the majority of children manifest resilience and do not experience any long-term negative consequences. However, a significant minority do and these children experience not one, but multiple problems, which frequently endure over time in the absence of support and opportunities for recovery. As a result, they are highly likely to suffer numerous and enduring impacts. These insights suggest a new strategic approach to interventions for children affected by HIV and AIDS, one that effectively combines a universal lattice of protection with intensive intervention targeted to selected children and families.

Perinatal mental disorders are associated with increased risk of psychological and developmental disturbances in children. However, these disturbances are not inevitable. In this Series paper, we summarise evidence for associations between parental disorders and offspring outcomes from fetal development to adolescence in high-income, middle-income, and low-income countries. We assess evidence for mechanisms underlying transmission of disturbance, the role of mediating variables (underlying links between parent psychopathology and offspring outcomes) and possible moderators (which change the strength of any association), and focus on factors that are potentially modifiable, including parenting quality, social (including partner) and material support, and duration of the parental disorder. We review research of interventions, which are mostly about maternal depression, and emphasise the need to both treat the parent's disorder and help with associated caregiving difficulties. We conclude with policy implications and underline the need for early identification of those parents at high risk and for more early interventions and prevention research, especially in socioeconomically disadvantaged populations and low-income countries.

Globally, there is a crucial need to prioritize research directed at reducing neurological, mental health and substance-use disorders in adolescence, which is a pivotal age for the development of self-control and regulation. In adolescence, behaviour optimally advances towards adaptive long-term goals and suppresses conflicting maladaptive short-lived urges to balance impulsivity, exploration and defiance, while establishing effective societal participation. When self-control fails to develop, violence, injury and neurological, mental health and substance-use disorders can result, further challenging the development of self-regulation and impeding the transition to a productive adulthood. Adolescent outcomes, positive and negative, arise from both a life-course perspective and within a socioecological framework. Little is known about the emergence of self-control and regulation in adolescents in low- and middle-income countries where enormous environmental threats are more common (for example, poverty, war, local conflicts, sex trafficking and slavery, early marriage and/or pregnancy, and the absence of adequate access to education) than in high-income countries and can threaten optimal neurodevelopment. Research must develop or adapt appropriate assessments of adolescent ability and disability, social inclusion and exclusion, normative development, and neurological, mental health and substance-use disorders. Socioecological challenges in low- and middle-income countries require innovative strategies to prevent mental health, neurological and substance-use disorders and develop effective interventions for adolescents at risk, especially those already living with these disorders and the consequent disability.

Alveolar (ARMS) and Embryonal (ERMS) rhabdomyosarcoma differ in their response to current treatments. The ARMS subtype has a less favourable prognosis and often presents with widespread metastases, while the less metastatic ERMS has a 5 year survival rate of more than 80 %. In this study we investigate gene expression differences that could contribute to the high frequency of metastasis in ARMS. Microarray analysis identified significant differences in DNA repair, cell cycle and cell migration between the two RMS subtypes. Two genes up regulated in ARMS and involved in cell migration; the engulfment and cell motility gene 1 (ELMO1) and NEL-like 1 gene (NELL1) were selected for further nvestigation. Over-expression of ELMO1 significantly increased cell invasion from 24.70 ± 7 % to 93 ± 5.4 % in primary myoblasts and from 29.43 ± 2.1 % to 87.33 ± 4.1 % in the ERMS cell line RD. siRNA knockout of ELMO1 in the ARMS cell line RH30 significantly reduced cell invasion from 88.2 ± 3.8 % to 35.2 ± 2.5 %. Over-expression of NELL1 significantly increased myoblast invasion from 23.6 ± 6.9 % to 100 ± 0.1 %, but had no effect on invasion of the ERMS cell line RD. These findings suggest that ELMO1 may play a key role in ARMS metastasis. NELL1 increased invasion in primary myoblasts, but other factors required for it to enhance motility were not present in the RD ERMS cell line. Impairing ELMO1 function by pharmacological or siRNA knockdown could be a highly effective approach to reduce the metastatic spread of RMS. © Springer Science+Business Media B.V. 2012.

We report significant and controlled cell death using novel x-ray-activatable titania nanoparticles (NPs) doped with lanthanides. Preferential incorporation of such materials into tumor tissue can enhance the effect of radiation therapy. Herein, the incorporation of gadolinium into the NPs is designed to optimize localized energy absorption from a conventional medical x-ray. This result is further optimized by the addition of other rare earth elements. Upon irradiation, energy is transferred to the titania crystal structure, resulting in the generation of reactive oxygen species (ROS). From the Clinical Editor The authors report significant and controlled cell death using x-ray-activated titania nanoparticles doped with lanthanides as enhancers. Upon irradiation X-ray energy is transferred to the titania crystal structure, resulting in the generation of reactive oxygen species.
