Developing a strategy to scale up place-based arts initiatives that support mental health and wellbeing: A realist evaluation of 'Arts for the Blues'. PLoS One 2024; 19:e0296178. [PMID: 38165951 PMCID: PMC10760705 DOI: 10.1371/journal.pone.0296178] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2023] [Accepted: 12/07/2023] [Indexed: 01/04/2024] Open
Abstract
Place-based arts initiatives are regarded as rooted in local need and as having capacity to engage local assets. However, many place-based arts initiatives remain poorly funded and short-lived, receiving little attention on how to scale up and sustain their activities. In this study we make a unique contribution to knowledge about scaling up place-based arts initiatives that support mental health and wellbeing through focusing on the example of 'Arts for the Blues', an arts-based psychological group intervention designed to reduce depression and improve wellbeing amongst primary care mental health service users in deprived communities. Methodologically, we used realist evaluation to refine the study's theoretical assumptions about scaling up, drawing on the lived and professional experiences of 225 diverse stakeholders' and frontline staff through a series of focus groups and evaluation questions at two stakeholders' events and four training days. Based on our findings, we recommend that to scale up place-based arts initiatives which support mental health and wellbeing: (i) the initiative needs to be adaptable, clear, collaborative, evidence-based, personalised and transformative; (ii) the organisation has to have a relevant need, have an understanding of the arts, has to have resources, inspiration and commitment from staff members, relevant skillsets and help from outside the organisation; (iii) at a policy level it is important to pay attention to attitude shifts towards the arts, meet rules, guidelines and standards expected from services, highlight gaps in provision, seek out early intervention and treatment options, and consider service delivery changes. The presence of champions at a local level and buy-in from managers, local leaders and policy makers are also needed alongside actively seeking to implement arts initiatives in different settings across geographical spread. Our theoretically-based and experientially-refined study provides the first ever scaling up framework developed for place-based arts initiatives that support the mental health and wellbeing, offering opportunities for spread and adoption of such projects in different organisational contexts, locally, nationally and internationally.

Abstract
INTRODUCTION Research over the last decade has identified both strengths and limitations in the use of routinely prescribed psychological therapies for depression. More recently, a focus on how creative art therapies and 'arts on prescription' are developing a growing recognition of their potential additional therapeutic mechanisms for depression. AIM In an attempt to develop a new therapeutic intervention for depression, this research aligned both the evidence base surrounding the arts on prescription movement, collating these with client-reported helpful factors and preferences for therapeutic interventions. METHODS We developed a framework for a new pluralistic 'meta-approach' of therapy for depression, based on; an interdisciplinary thematic synthesis of active ingredients, considered specific features implemented in therapy, and client-reported helpful factors considered to be the broad features or experiences in therapy from both talking therapies and creative approaches. This framework contributed to the development of a pilot workshop entitled Arts for the Blues - A New Creative Psychological Therapy for Depression. An outline of, and evaluation from this workshop is presented in this article. Workshop participants were recruited via a voluntary workshop taking place at a North West Higher Education Institution Arts and Health conference ( N = 15). RESULTS The workshop was evaluated using quantitative measures, with results indicating around a 70% overall satisfaction, followed up with qualitative commentary around areas of good practice and areas for development. These included the positive reflection on the application of creative arts and the multimodal nature of the approach, while others reflected on the potential overwhelming nature of utilising multimodal methods for individuals with depression. CONCLUSION Overall feedback from the pilot workshop is discussed in relation to prior research, giving credence to the potential for incorporating arts into therapy.

Abstract
Nearly 80% of cancer patients do not have genetic mutation results available at initial oncology consultation; up to 25% of patients begin treatment before receiving their results. These factors hinder the ability to pursue optimal treatment strategies. This study validates a blood-based genome-testing service that provides accurate results within 72 hours. We focused on targetable variants in advanced non-small cell lung carcinoma-epidermal growth factor receptor gene (EGFR) variant L858R, exon 19 deletion (ΔE746-A750), and T790M; GTPase Kirsten ras gene (KRAS) variants G12C/D/V; and echinoderm microtubule associated protein like and 4 anaplastic lymphoma receptor tyrosine kinase fusion (EML4-ALK) transcripts 1/2/3. Test development included method and clinical validation using samples from donors with (n = 219) or without (n = 30) cancer. Clinical sensitivity and specificity for each variant ranged from 78.6% to 100% and 94.2% to 100%, respectively. We also report on 1643 non-small cell lung carcinoma samples processed in our CLIA-certified laboratory. Mutation results were available within 72 hours for 94% of the tests evaluated. We detected 10.5% mutations for EGFR sensitizing (n = 2801 samples tested), 13.8% mutations for EGFR resistance (n = 1055), 13.2% mutations in KRAS (n = 3477), and 2% mutations for EML4-ALK fusion (n = 304). This rapid, highly sensitive, and actionable blood-based assay service expands testing options and supports faster treatment decisions.

Abstract
Abstract
Time to treatment can have significant impact on progression of cancer, and treatment decisions rely heavily upon genomic and proteomic testing. However, multiple factors can delay the availability of molecular diagnostic test results, including the use of tissue-based testing. Almost one third of patients with non-small cell lung cancer (NSCLC) are either not candidates for biopsies, or have insufficient tissue samples from their initial biopsy. Additionally, most physicians in the community setting want to initiate treatment quickly but do not have access to on-site molecular testing at their practice. As a result, physicians may delay their decision to commence treatment with specific targeted therapies or treat before the mutation status is known. The goal of this study was to assess the utility of a blood-based cell-free (cf) nucleic acid Laboratory Developed Test (LDT) in the community setting. The tests utilize Droplet Digital™ PCR (ddPCR) technology to detect the EGFR sensitizing mutations L858R and exon 19 deletion (E746 - A750), the EGFR resistance mutation (T790M), the KRAS mutations G12C, G12V and G12D, and the BRAF V600E mutation. Patient samples for testing were collected and shipped at ambient room temperature using a Biodesix® whole blood sample collection kit and processed at the Biodesix laboratory. Metrics were reviewed from the real-time measurement of established molecular diagnostic markers in the plasma of patients with NSCLC. For this study we analyzed results from greater than 4,000 patient cases (~24,000 individual variants). Greater than 70% of test orders were received from physician practices that self-identified as community based. Test mutation status results were reported within 72 hours of sample receipt from the physician’s office (95%). The percentage of tests requested that were positive for each variant category were 9% for EGFR sensitizing, 9% for EGFR resistance, 11% for KRAS, and 1% for BRAF. Notably, we generated test results successfully for 98% of tests submitted. We have developed fast, highly robust and sensitive blood-based assays to expedite time to treatment and expand the laboratory testing options for patients with NSCLC.

Abstract
Abstract
Nearly 80% of patients will not have mutation results available at their initial oncology consult and as many as 1 in 4 patients will begin treatment in advance of receiving their tumor mutation results. These factors hinder diagnosis at the molecular level, which is an important component in the decision to commence treatment with specific targeted therapies. The goal of this study was to measure the utility of a CLIA-certified Laboratory Developed Test (LDT) in the absence of a tissue diagnosis. EGFR, KRAS and BRAF point mutations within the cell-free DNA (cfDNA) isolated from the plasma of patients with advanced stages of cancer were analyzed using Droplet Digital™ PCR (ddPCR) technology. The specific tests detected the EGFR sensitizing mutations L858R and exon 19 deletion (E746 - A750) and EGFR resistance mutation, T790M, the KRAS mutations G12C, G12V and G12D, as well as the BRAF V600E mutation. The tests were comprised of three components: (i) a whole-blood collection kit that ships at ambient temperature, (ii) cfDNA isolated from plasma for analysis using ddPCR, and (iii) a secure laboratory information management system (LIMS) for sample accessioning and report generation. Test mutation status results were reported within 72 hours of blood shipment from the physicians’ office. To date we have processed greater than 2000 individual variant tests for patients with NSCLC. The predominant tumor type for EGFR sensitizing mutations requested was NSCLC (95%). Interestingly, even BRAF test orders were > 90% from NSCLC patients. Additionally, the percentage of tests requested that were positive for each mutation category were 12% for EGFR sensitizing, 20% for EGFR resistance, 14% for KRAS and 1.8% for BRAF. Significantly, T790M test orders were observed to have increased five-fold over the last three months of testing. We have developed highly sensitive, 72 hour test to results blood-based assays as a part of the GeneStratTM panel, that expand the utility of laboratory testing for patients previously diagnosed with cancer.

Abstract
This is a case report of a 27-year-old male who sustained a stab wound to the chest with a resulting penetrating cardiac injury and subsequent emergency thoracotomy. The patient survived his injury and on post-op day two, a holosystolic murmur was noted during physical exam, but he remained hemodynamically stable and intubated. A transthoracic echocardiogram revealed the presence of a ventricular septal defect (VSD), with Doppler flow revealing shunting from the left ventricular cavity into the right ventricular cavity. Ultimately, the clinicians decided upon a trial of extubation with a plan for delayed closure of the VSD. Upon extubation,the patient became hypoxemic with evidence of pulmonary edema; thus, he was re-intubated. The defect was surgically repaired, and the patient had an uneventful recovery thereafter. The purpose of this case report is to present an example of delayed detection of a ventricular septal defect after a penetrating cardiac injury.

The genome of Mycobacterium africanum West African 2 reveals a lineage-specific locus and genome erosion common to the M. tuberculosis complex. PLoS Negl Trop Dis 2012; 6:e1552.

Abstract
Background M. africanum West African 2 constitutes an ancient lineage of the M. tuberculosis complex that commonly causes human tuberculosis in West Africa and has an attenuated phenotype relative to M. tuberculosis. Methodology/Principal Findings In search of candidate genes underlying these differences, the genome of M. africanum West African 2 was sequenced using classical capillary sequencing techniques. Our findings reveal a unique sequence, RD900, that was independently lost during the evolution of two important lineages within the complex: the “modern” M. tuberculosis group and the lineage leading to M. bovis. Closely related to M. bovis and other animal strains within the M. tuberculosis complex, M. africanum West African 2 shares an abundance of pseudogenes with M. bovis but also with M. africanum West African clade 1. Comparison with other strains of the M. tuberculosis complex revealed pseudogenes events in all the known lineages pointing toward ongoing genome erosion likely due to increased genetic drift and relaxed selection linked to serial transmission-bottlenecks and an intracellular lifestyle. Conclusions/Significance The genomic differences identified between M. africanum West African 2 and the other strains of the Mycobacterium tuberculosis complex may explain its attenuated phenotype, and pave the way for targeted experiments to elucidate the phenotypic characteristic of M. africanum. Moreover, availability of the whole genome data allows for verification of conservation of targets used for the next generation of diagnostics and vaccines, in order to ensure similar efficacy in West Africa. Mycobacterium africanum, a close relative of M. tuberculosis, is studied for the following reasons: M. africanum is commonly isolated from West African patients with tuberculosis yet has not spread beyond this region, it is more common in HIV infected patients, and it is less likely to lead to tuberculosis after one is exposed to an infectious case. Understanding this organism's unique biology gets a boost from the decoding of its genome, reported in this issue. For example, genome analysis reveals that M. africanum contains a region shared with “ancient” lineages in the M. tuberculosis complex and other mycobacterial species, which was lost independently from both M. tuberculosis and M. bovis. This region encodes a protein involved in transmembrane transport. Furthermore, M. africanum has lost genes, including a known virulence gene and genes for vitamin synthesis, in addition to an intact copy of a gene that may increase its susceptibility to antibiotics that are insufficiently active against M. tuberculosis. Finally, the genome sequence and analysis reported here will aid in the development of new diagnostics and vaccines against tuberculosis, which need to take into account the differences between M. africanum and other species in order to be effective worldwide.

Abstract
BACKGROUND Families supporting children with complex needs are significantly more distressed and economically disadvantaged than families of children without disability and delay. What is not known is the associations and costs of parental psychiatric distress within a multi-diagnosis group of special needs children. METHODS In this cross-sectional survey, families were identified from the Children's Treatment Network. Families were eligible if the child was aged 0-19 years, resided in Simcoe/York, and if there were multiple family needs (n = 429). RESULTS Some 42% of surveyed parents exhibited symptoms (mild to severe) of psychiatric distress. The presence of these symptoms was associated with reports of poorer social support, family dysfunction, greater adverse impact of the child's situation on the family, poorer child behaviour, unfavourable parenting styles and poorer child psychosocial functioning. The severity of the child's physical dysfunction was not related to parents/guardians most knowledgeable symptoms of psychiatric distress. Total parent costs were higher and children's uses of primary care services were higher in parents with symptoms of psychiatric distress. CONCLUSION Parent symptoms of psychiatric distress are a significant societal concern in families with complex needs children. Children's rehabilitation efforts need to incorporate parental mental health assessment and treatment into existing programmes. This could lead to decreases in direct and indirect healthcare utilisation costs.

The genome sequence of the fish pathogen Aliivibrio salmonicida strain LFI1238 shows extensive evidence of gene decay. BMC Genomics 2008; 9:616.

Abstract
Background The fish pathogen Aliivibrio salmonicida is the causative agent of cold-water vibriosis in marine aquaculture. The Gram-negative bacterium causes tissue degradation, hemolysis and sepsis in vivo. Results In total, 4 286 protein coding sequences were identified, and the 4.6 Mb genome of A. salmonicida has a six partite architecture with two chromosomes and four plasmids. Sequence analysis revealed a highly fragmented genome structure caused by the insertion of an extensive number of insertion sequence (IS) elements. The IS elements can be related to important evolutionary events such as gene acquisition, gene loss and chromosomal rearrangements. New A. salmonicida functional capabilities that may have been aquired through horizontal DNA transfer include genes involved in iron-acquisition, and protein secretion and play potential roles in pathogenicity. On the other hand, the degeneration of 370 genes and consequent loss of specific functions suggest that A. salmonicida has a reduced metabolic and physiological capacity in comparison to related Vibrionaceae species. Conclusion Most prominent is the loss of several genes involved in the utilisation of the polysaccharide chitin. In particular, the disruption of three extracellular chitinases responsible for enzymatic breakdown of chitin makes A. salmonicida unable to grow on the polymer form of chitin. These, and other losses could restrict the variety of carrier organisms A. salmonicida can attach to, and associate with. Gene acquisition and gene loss may be related to the emergence of A. salmonicida as a fish pathogen.

Abstract
Plasmodium knowlesi is an intracellular malaria parasite whose natural vertebrate host is Macaca fascicularis (the 'kra' monkey); however, it is now increasingly recognized as a significant cause of human malaria, particularly in southeast Asia. Plasmodium knowlesi was the first malaria parasite species in which antigenic variation was demonstrated, and it has a close phylogenetic relationship to Plasmodium vivax, the second most important species of human malaria parasite (reviewed in ref. 4). Despite their relatedness, there are important phenotypic differences between them, such as host blood cell preference, absence of a dormant liver stage or 'hypnozoite' in P. knowlesi, and length of the asexual cycle (reviewed in ref. 4). Here we present an analysis of the P. knowlesi (H strain, Pk1(A+) clone) nuclear genome sequence. This is the first monkey malaria parasite genome to be described, and it provides an opportunity for comparison with the recently completed P. vivax genome and other sequenced Plasmodium genomes. In contrast to other Plasmodium genomes, putative variant antigen families are dispersed throughout the genome and are associated with intrachromosomal telomere repeats. One of these families, the KIRs, contains sequences that collectively match over one-half of the host CD99 extracellular domain, which may represent an unusual form of molecular mimicry.

Abstract
Leishmania parasites cause a broad spectrum of clinical disease. Here we report the sequencing of the genomes of two species of Leishmania: Leishmania infantum and Leishmania braziliensis. The comparison of these sequences with the published genome of Leishmania major reveals marked conservation of synteny and identifies only approximately 200 genes with a differential distribution between the three species. L. braziliensis, contrary to Leishmania species examined so far, possesses components of a putative RNA-mediated interference pathway, telomere-associated transposable elements and spliced leader-associated SLACS retrotransposons. We show that pseudogene formation and gene loss are the principal forces shaping the different genomes. Genes that are differentially distributed between the species encode proteins implicated in host-pathogen interactions and parasite survival in the macrophage.

Forty-eight subjects from three age groups were randomly divided into 8 experimental groups: (1) simultaneous footrest vibration and back vibration (A1C1); (2) simultaneous footrest vibration and back roller (A1C2); (3) simultaneous footrest vibration, back vibration and back roller (A1C3); (4) footrest vibration alone (A1C4): (5) back vibration alone (A2C1); (6) back roller alone (A2C2); (7) simultaneous back vibration and back roller (A2C3); and (8) control group (no vibration/stimulation) (A2C4). The three major variables studied were footrest vibration (A1 and A2), pre- and post-EMG measures (B1 and B2), and back vibration (C1C2C3C4). Results showed that footrest vibration had a significant effect on relaxation. Other conditions (except the control) produced a decrease in EMG levels, but did not reach significance. Pre- and postmeasures by experimental conditions were also significantly different. Application of vibration as an aid in relaxation is discussed.
