Prevalence and Risk Factors for Moral Distress in Pediatric Oncology Health Care Professionals.

PURPOSE: Moral distress (MoD) is prevalent among health care professionals (HCPs) in oncology and is associated with burnout. The objectives of this study were to quantify MoD among pediatric oncology healthcare professionals (HCPs) at a Canadian quaternary care hospital, identify root causes, and evaluate change over time. METHODS: Eligible pediatric oncology HCPs were identified, and consenting participants completed the Measure of Moral Distress-Healthcare Professionals (MMD-HP) and MoD Thermometer (MDT) at baseline, followed by biweekly MDTs over 12 weeks. RESULTS: A total of 139 HCPs participated. The mean MMD-HP score was 123 ± 57.0, range 9-288. Demographic risk factors identified for elevated MMD-HP scores were female sex (female 127.1 and male 83.6, P = .01) and nursing role (nurse 136.3 and most responsible physician 85.3, P = .02). Higher MMD-HP scores were found in HCPs who were currently considering resigning because of MoD compared with those who were not (169.9 v 115.4, P < .001). Situations involving administration of treatment to children with poor prognosis cancers that was perceived to be overly aggressive were ranked as the greatest environmental contributor to MoD. Baseline and mean MDT scores over time strongly correlated with MMD-HP scores (P < .0001 and P = .0003, respectively), with mean MDT scores showing no significant fluctuation over the 12-week period. CONCLUSION: MoD was common among pediatric oncology HCPs. Risk factors for elevated levels of MoD included both demographic and environmental factors. Implementation of systems to improve team communication and decision making, especially in the care of patients with poor prognosis cancers, may affect HCP MoD.

Impact of COVID-19 control on lung, breast, and colorectal pathological cancer diagnoses. A comparison between the Netherlands, Aotearoa New Zealand, and Northern Ireland.

BACKGROUND: The COVID-19 pandemic was managed in Aotearoa New Zealand (NZ) by a COVID-19 elimination policy, involving border closure and an initial national lockdown. This was different to most other countries including Northern Ireland (NI) and the Netherlands (NED). We quantify the effect of these policies on the diagnosis of three major cancers, comparing NZ with these two European countries. METHOD: Data from NED, NZ and NI population-based cancer registries were used to assess trends in all pathologically diagnosed (PD) lung, breast, and colorectal cancers from March to December 2020 (pandemic period) and compared to the similar pre-pandemic period (2017-2019). Trend data were also collated on COVID-19 cases and deaths per 100,000 in each population. RESULTS: Comparing the pre-pandemic period to the pandemic period there were statistically significant reductions in numbers of lung (↓23%) and colorectal (↓15%) PD cancers in NI and numbers of breast (↓18%) and colorectal cancer (↓18.5%) diagnosed in the NED. In NZ there was no significant change in the number of lung (↑10%) or breast cancers (↑0.2%) but a statistically significant increase in numbers of colorectal cancer diagnosed (↑5%). CONCLUSION: The impact of COVID-19 on cancer services was mitigated in NZ as services continued as usual reflecting minimal healthcare disruption and protected cancer services linked with the elimination approach adopted. The reduction in PD cases diagnosed in NED and NI were linked with higher COVID-19 rates and reflect societal restrictions which resulted in delayed patient presentation to primary and secondary care, disruption to screening and healthcare services as a result of COVID-19 infections on staff and the need to shift intensive care to COVID-19 patients. Reductions in PD cancers in NI and the NED and in particularly lung cancers in NI, highlight the need for targeted public health campaigns to identify and treat 'missing' patients. Protecting cancer services should be a priority in any future pandemic or systemic healthcare system disruption.

Characterizing asset-based studies in public health: development of a framework.

Asset-based approaches are becoming more common within public health interventions; however, due to variations in terminology, it can be difficult to identify asset-based approaches. The study aimed to develop and test a framework that could distinguish between asset-based and deficit-based community studies, whilst acknowledging there is a continuum of approaches. Literature about asset-based and deficit-based approaches were reviewed and a framework was developed based on the Theory of Change model. A scoring system was developed for each of the five elements in the framework based on this model. Measurement of community engagement was built in, and a way of capturing how much the study involved an asset approach. The framework was tested on 13 studies examining community-based interventions to investigate whether it could characterize asset-based versus deficit-based studies. The framework demonstrated how much the principles underpinning asset-based approaches were present and distinguished between studies where the approach was deficit-based to those that had some elements of an asset-based approach. This framework is useful for researchers and policymakers when determining how much of an intervention is asset-based and identifying which elements of asset-based approaches lead to an intervention working.

Deficit-based approaches are a common approach to addressing public health issues within a community and involve identifying a health problem or need and finding a way to solve these. However, asset-based approaches, those that involve the community using its assets, or strengths, to enable community members to have more control over their health and wellbeing, are increasingly common. The terminology used to describe these methods varies greatly so it can be difficult to identify whether an approach is more deficit-based or asset-based. To address this a framework was developed to identify and score elements of asset-based studies. We did this by reviewing academic information describing asset-based approaches and built into this a scoring system. This framework was used to assess and measure the degree to which 13 community-based studies took an asset-based approach. The framework was able to identify studies which were more asset-based in their approach compared to those which were more deficit-focused, acknowledging that some studies may have elements of each approach. This framework will be useful for people working in health policy and research who want a resource to help identify asset-based approaches in practice and which aspects of the approach were important for its success in the community.

Common health assets protocol: a mixed-methods, realist evaluation and economic appraisal of how community-led organisations (CLOs) impact on the health and well-being of people living in deprived areas.

INTRODUCTION: This research investigates how community-led organisations' (CLOs') use of assets-based approaches improves health and well-being, and how that might be different in different contexts. Assets-based approaches involve 'doing with' rather than 'doing to' and bring people in communities together to achieve positive change using their own knowledge, skills and experience. Some studies have shown that such approaches can have a positive effect on health and well-being. However, research is limited, and we know little about which approaches lead to which outcomes and how different contexts might affect success. METHODS AND ANALYSIS: Using a realist approach, we will work with 15 CLOs based in disadvantaged communities in England, Scotland and Northern Ireland. A realist synthesis of review papers, and a policy analysis in different contexts, precedes qualitative interviews and workshops with stakeholders, to find out how CLOs' programmes work and identify existing data. We will explore participants' experiences through: a Q methodology study; participatory photography workshops; qualitative interviews and measure outcomes using a longitudinal survey, with 225 CLO participants, to assess impact for people who connect with the CLOs. An economic analysis will estimate costs and benefits to participants, for different contexts and mechanisms. A 'Lived Experience Panel' of people connected with our CLOs as participants or volunteers, will ensure the appropriateness of the research, interpretation and reporting of findings. ETHICS AND DISSEMINATION: This project, research tools and consent processes have been approved by the Glasgow Caledonian University School of Health and Life Sciences Ethics Committee, and affirmed by Ethics Committees at Bournemouth University, Queen's University Belfast and the University of East London. Common Health Assets does not involve any National Health Service sites, staff or patients.Findings will be presented through social media, project website, blogs, policy briefings, journal articles, conferences and visually in short digital stories, and photographic exhibitions.

Pediatric hematology/oncology healthcare professional emotional health during COVID-19.

OBJECTIVES: Little is known about the impact of coronavirus disease 2019 (COVID-19) on healthcare professional emotional health in pediatric hematology/oncology. Primary objective was to describe anxiety, depression, positive affect, and perceived stress among pediatric hematology/oncology healthcare professionals following a COVID-19 outbreak. Secondary objectives were to compare these outcomes based on contact with a positive person, and to identify risk factors for worse outcomes. MATERIALS AND METHODS: We included 272 healthcare professionals working with pediatric hematology/oncology patients. We determined whether respondents had direct or indirect contact with a COVID-19-positive individual and then measured outcomes using the Patient-Reported Outcomes Measurement Information System (PROMIS) depression, anxiety, and positive affect measures, and the Perceived Stress Scale. RESULTS: Among eligible respondents, 205 agreed to participate (response rate 75%). Sixty-nine (33.7%) had contact with a COVID-19-positive person. PROMIS anxiety, depression, and positive affect scores were similar to the general United States population. Those who had contact with a COVID-19-positive individual did not have significantly different outcomes. In multiple regression, non-physicians had significantly increased anxiety (nurses: p = 0.013), depression (nurses: p = 0.002, pharmacists: p = 0.038, and other profession: p = 0.021), and perceived stress (nurses: p = 0.002 and other profession: p = 0.011) when compared to physicians. CONCLUSIONS: Pediatric hematology/oncology healthcare professionals had similar levels of anxiety, depression, and positive affect as the general population. Contact with a COVID-19-positive individual was not significantly associated with outcomes. Non-physician healthcare professionals had more anxiety, depression, and perceived stress when compared to physicians. These findings may help to develop programs to support healthcare professional resilience.

Characterizing the BCG Induced Macrophage and Neutrophil Mechanisms for Defense Against Mycobacterium tuberculosis.

The live attenuated Mycobacterium bovis strain, Bacille Calmette Guérin (BCG) is a potent innate immune stimulator. In the C57BL/6 mouse model of tuberculosis, BCG vaccination leads to a significant reduction of Mycobacterium tuberculosis burden after aerogenic infection. Our studies indicated that BCG induced protection against pulmonary tuberculosis was independent of T cells and present as early as 7 days after vaccination. This protection showed longevity, as it did not wane when conventional T cell and TNF-α deficient mice were infected 30 days post-vaccination. As BCG induced mycobacterial killing after 7 days, this study investigated the contributions of the innate immune system after BCG vaccination to better understand mechanisms required for mycobacterial killing. Subcutaneous BCG inoculation resulted in significant CD11b+F4/80+ monocyte subset recruitment into the lungs within 7 days. Further studies revealed that killing of mycobacteria was dependent on the viability of BCG, because irradiated BCG did not have the same effect. Although others have identified BCG as a facilitator of trained innate immunity, we found that BCG reduced the mycobacterial burden in the absence of mechanisms required for trained innate immunity, highlighting a role for macrophages and neutrophils for vaccine induced killing of M. tuberculosis.

Lineage of measurable residual disease in patients with chronic myeloid leukemia in treatment-free remission.

Approximately half of patients with chronic myeloid leukemia (CML) in sustained deep molecular response who discontinue tyrosine kinase inhibitors (TKIs) remain in treatment-free remission (TFR). Some of these patients have measurable residual disease (MRD) by BCR-ABL1 mRNA testing, and most have detectable BCR-ABL1 DNA by highly sensitive methods. We used fluorescence-activated cell sorting and BCR-ABL1 DNA PCR to investigate the lineage of residual CML cells in TFR. Twenty patients in TFR for >1 year provided blood for sorting into granulocytes, monocytes, B cells, T cells, and NK cells. MRD was identified predominantly in the lymphoid compartment and never in granulocytes. B cells were more often BCR-ABL1 positive than T cells (18 vs 11/20 patients) and at higher levels (median 10-4.9 vs 10-5.7; P = 0.014). In 13 CML patients studied at diagnosis lymphocytes expressing BCR-ABL1 mRNA comprised a small proportion of total leukocytes. These data improve our understanding of TFR biology, since it is now clear that MRD in the blood of TFR patients need not imply the persistence of multipotent CML cells. Lineage-specific assessment of MRD could be explored as a means to improve the prediction of TFR.

Modelling ponatinib resistance in tyrosine kinase inhibitor-naïve and dasatinib resistant BCR-ABL1+ cell lines.

TKI resistance remains a major impediment to successful treatment of CML. In this study, we investigated the emerging modes of ponatinib resistance in TKI-naïve and dasatinib resistant BCR-ABL1+ cell lines. To investigate potential resistance mechanisms, ponatinib resistance was generated in BCR-ABL1+ cell-lines by long-term exposure to increasing concentrations of ponatinib. Two cell lines with prior dasatinib resistance demonstrated BCR-ABL1 kinase domain (KD) mutation(s) upon exposure to ponatinib. In one of these cell lines the T315I mutation had emerged during dasatinib exposure. When further cultured with ponatinib, the T315I mutation level and BCR-ABL1 mRNA expression level were increased. In the other cell line, compound mutations G250E/E255K developed with ponatinib exposure. In contrast, the ponatinib resistant cell lines that had no prior exposure to other TKIs (TKI-naïve) did not develop BCR-ABL1 KD mutations. Rather, both of these cell lines demonstrated Bcr-Abl-independent resistance via Axl overexpression. Axl, a receptor tyrosine kinase, has previously been associated with imatinib and nilotinib resistance. Ponatinib sensitivity was restored following Axl inhibition or shRNA-mediated-knockdown of Axl, suggesting that Axl was the primary driver of resistance and a potential target for therapy in this setting.

Media reporting of health interventions in New Zealand: a retrospective analysis.

AIM: To evaluate New Zealand media articles on their coverage of key issues regarding health interventions and whether it is consistent with available evidence. METHODS: A retrospective analysis was carried out of all articles published in five New Zealand media sources over a 6-week period between 15 October and 26 November 2014. Articles were included if their primary focus was on health interventions involving medications, devices or in-hospital procedures. Articles were assessed for coverage of key issues using previously validated 10-point criteria. A literature review was performed to compare content with scientific evidence. RESULTS: We identified 30 articles for review. Only 4 of 30 articles covered indications, benefits and risks, and of these, two were consistent with available evidence (7%, 95% CI 1%-22%). For articles that discussed at least one of indications, benefits or risks, and there was corresponding evidence available, there was a high level of consistency with the evidence (89%, 95% CI 77%-95%). The overall mean value of coverage from the 10-point criteria was 51% (95% CI 45%-58%). Single questions regarding the potential harm, costs associated with the intervention and the availability of alternative options were particularly poorly covered. They were rated as 'satisfactory' in 13%, 23% and 33% of the 30 articles respectively. CONCLUSION: New Zealand news articles covering medical treatments and interventions are largely consistent with available evidence but are incomplete. Vital information is being consistently missed, especially around the potential harms and costs of medical interventions.

Use of Short Animal-Themed Videos to Enhance Veterinary Students' Mood, Attention, and Understanding of Pharmacology Lectures.

Professional DVM training is inherently stressful and challenging for students. This study evaluated a simple intervention-short breaks during a veterinary pharmacology lecture course in the form of funny/cute animal videos (Mood Induction Procedures, or MIP)-to assess for potential impact on students' mood, interest in material, and perceived understanding of material. Ten YouTube video clips showing cats or dogs were selected to influence students' affective states. The videos were shown in a required pharmacology class offered during the fall semester of the second year of the DVM program at a large, land-grant institution in the western US. The student cohort consisted of 133 students (20 males, 113 females). Twenty days of the course were randomly chosen for the study and ranged from weeks 2 to 13 of the semester. Sessions in which the videos were played were alternated with sessions in which no video was played, for a total of 10 video days and 10 control days. There were significant differences in all three post-class assessment measures between the experimental (video) days and the control days. Results suggest that showing short cute animal videos in the middle of class positively affected students' mood, interest in material, and self-reported understanding of material. While the results of this study are limited to one student cohort at one institution, the ease of implementation of the technique and relatively low stakes support incorporation of the MIP technique across a variety of basic and clinical science courses.

Humanized NOG mice as a model for tuberculosis vaccine-induced immunity: a comparative analysis with the mouse and guinea pig models of tuberculosis.

The humanized mouse model has been developed as a model to identify and characterize human immune responses to human pathogens and has been used to better identify vaccine candidates. In the current studies, the humanized mouse was used to determine the ability of a vaccine to affect the immune response to infection with Mycobacterium tuberculosis. Both human CD4+ and CD8+ T cells responded to infection in humanized mice as a result of infection. In humanized mice vaccinated with either BCG or with CpG-C, a liposome-based formulation containing the M. tuberculosis antigen ESAT-6, both CD4 and CD8 T cells secreted cytokines that are known to be required for induction of protective immunity. In comparison to the C57BL/6 mouse model and Hartley guinea pig model of tuberculosis, data obtained from humanized mice complemented the data observed in the former models and provided further evidence that a vaccine can induce a human T-cell response. Humanized mice provide a crucial pre-clinical platform for evaluating human T-cell immune responses in vaccine development against M. tuberculosis.

Technology and tuberculosis control: the OUT-TB Web experience.

OBJECTIVE: Develop a tool to disseminate integrated laboratory, clinical, and demographic case data necessary for improved contact tracing and outbreak detection of tuberculosis (TB). METHODS: In 2007, the Public Health Ontario Laboratories implemented a universal genotyping program to monitor the spread of TB strains within Ontario. Ontario Universal Typing of TB (OUT-TB) Web utilizes geographic information system (GIS) technology with a relational database platform, allowing TB control staff to visualize genotyping matches and microbiological data within the context of relevant epidemiological and demographic data. RESULTS: OUT-TB Web is currently available to the 8 health units responsible for >85% of Ontario's TB cases and is a valuable tool for TB case investigation. Users identified key features to implement for application enhancements, including an e-mail alert function, customizable heat maps for visualizing TB and drug-resistant cases, socioeconomic map layers, a dashboard providing TB surveillance metrics, and a feature for animating the geographic spread of strains over time. CONCLUSION: OUT-TB Web has proven to be an award-winning application and a useful tool. Developed and enhanced using regular user feedback, future versions will include additional data sources, enhanced map and line-list filter capabilities, and development of a mobile app.

Heat killed Saccharomyces cerevisiae as an adjuvant for the induction of vaccine-mediated immunity against infection with Mycobacterium tuberculosis.

The use of novel vaccine delivery systems allows for the manipulation of the adaptive immune systems through the use of molecular adjuvants that target specific innate pathways. Such strategies have been used extensively for vaccines against cancer and multiple pathogens such as Mycobacterium tuberculosis. In the current study we used heat killed non-pathogenic recombinant Saccharomyces cerevisiae expressing M. tuberculosis antigen Rv1886c (fbpB, mpt59, Ag85B) as a delivery system in conjunction with its ability to stimulate innate immunity to determine its ability to induce immunity. We established that the recombinant yeast induced activated antigen specific T cells are capable of reducing the mycobacterial burden. Inoculation of the recombinant yeast after vaccination with BCG resulted in a systemic alteration of the phenotype of the immune response although this was not reflected in an increase in the reduction of the mycobacterial burden. Taken together the data suggest that heat killed yeast can induce multiple cytokines required for induction of protective immunity and can function as a vehicle for delivery of M. tuberculosis antigens in a vaccine formulation. In addition, while it can enhance the effector memory response induced by BCG, it had little effect on central memory responses.

The association between social capital and mental health and behavioural problems in children and adolescents: an integrative systematic review.

BACKGROUND: Mental health is an important component of overall health and wellbeing and crucial for a happy and meaningful life. The prevalence of mental health problems amongst children and adolescent is high; with estimates suggesting 10-20% suffer from mental health problems at any given time. These mental health problems include internalising (e.g. depression and social anxiety) and externalising behavioural problems (e.g. aggression and anti-social behaviour). Although social capital has been shown to be associated with mental health/behavioural problems in young people, attempts to consolidate the evidence in the form of a review have been limited. This integrative systematic review identified and synthesised international research findings on the role and impact of family and community social capital on mental health/behavioural problems in children and adolescents to provide a consolidated evidence base to inform future research and policy development. METHODS: Nine electronic databases were searched for relevant studies and this was followed by hand searching. Identified literature was screened using review-specific inclusion/exclusion criteria, the data were extracted from the included studies and study quality was assessed. Heterogeneity in study design and outcomes precluded meta-analysis/meta-synthesis, the results are therefore presented in narrative form. RESULTS: After screening, 55 studies were retained. The majority were cross-sectional surveys and were conducted in North America (n = 33); seven were conducted in the UK. Samples ranged in size from 29 to 98,340. The synthesised results demonstrate that family and community social capital are associated with mental health/behavioural problems in children and adolescents. Positive parent-child relations, extended family support, social support networks, religiosity, neighbourhood and school quality appear to be particularly important. CONCLUSIONS: To date, this is the most comprehensive review of the evidence on the relationships that exist between social capital and mental health/behavioural problems in children and adolescents. It suggests that social capital generated and mobilised at the family and community level can influence mental health/problem behaviour outcomes in young people. In addition, it highlights key gaps in knowledge where future research could further illuminate the mechanisms through which social capital works to influence health and wellbeing and thus inform policy development.

The envirome and the connectome: exploring the structural noise in the human brain associated with socioeconomic deprivation.

Complex cognitive functions are widely recognized to be the result of a number of brain regions working together as large-scale networks. Recently, complex network analysis has been used to characterize various structural properties of the large-scale network organization of the brain. For example, the human brain has been found to have a modular architecture i.e., regions within the network form communities (modules) with more connections between regions within the community compared to regions outside it. The aim of this study was to examine the modular and overlapping modular architecture of the brain networks using complex network analysis. We also examined the association between neighborhood level deprivation and brain network structure-modularity and gray nodes. We compared network structure derived from anatomical MRI scans of 42 middle-aged neurologically healthy men from the least (LD) and the most deprived (MD) neighborhoods of Glasgow with their corresponding random networks. Cortical morphological covariance networks were constructed from the cortical thickness derived from the MRI scans of the brain. For a given modularity threshold, networks derived from the MD group showed similar number of modules compared to their corresponding random networks, while networks derived from the LD group had more modules compared to their corresponding random networks. The MD group also had fewer gray nodes-a measure of overlapping modular structure. These results suggest that apparent structural difference in brain networks may be driven by differences in cortical thicknesses between groups. This demonstrates a structural organization that is consistent with a system that is less robust and less efficient in information processing. These findings provide some evidence of the relationship between socioeconomic deprivation and brain network topology.

Cardio-metabolic risk factors and cortical thickness in a neurologically healthy male population: Results from the psychological, social and biological determinants of ill health (pSoBid) study.

INTRODUCTION: Cardio-metabolic risk factors have been associated with poor physical and mental health. Epidemiological studies have shown peripheral risk markers to be associated with poor cognitive functioning in normal healthy population and in disease. The aim of the study was to explore the relationship between cardio-metabolic risk factors and cortical thickness in a neurologically healthy middle aged population-based sample. METHODS: T1-weighted MRI was used to create models of the cortex for calculation of regional cortical thickness in 40 adult males (average age = 50.96 years), selected from the pSoBid study. The relationship between cardio-vascular risk markers and cortical thickness across the whole brain, was examined using the general linear model. The relationship with various covariates of interest was explored. RESULTS: Lipid fractions with greater triglyceride content (TAG, VLDL and LDL) were associated with greater cortical thickness pertaining to a number of regions in the brain. Greater C reactive protein (CRP) and intercellular adhesion molecule (ICAM-1) levels were associated with cortical thinning pertaining to perisylvian regions in the left hemisphere. Smoking status and education status were significant covariates in the model. CONCLUSIONS: This exploratory study adds to a small body of existing literature increasingly showing a relationship between cardio-metabolic risk markers and regional cortical thickness involving a number of regions in the brain in a neurologically normal middle aged sample. A focused investigation of factors determining the inter-individual variations in regional cortical thickness in the adult brain could provide further clarity in our understanding of the relationship between cardio-metabolic factors and cortical structures.
