The story of the first-ever care experienced history month

The first-ever Care Experienced History Month took place in April 2021. Announced in Scotland in September 2020, Care Experienced History Month was celebrated across the world by Care Experienced people and their allies. The month aimed to draw attention to the rich and far-reaching history of Care Experienced people by connecting the past with the present and sharing the legacies of Care Experienced people who lived before us. This article explores the process that led to the creation of Care Experienced History Month, worldwide collaborations involved in the delivery of the month, the overall aims of the month, and an overview of the content created and shared throughout April 2021

Same-sex partner bereavement in older women:an interpretative phenomenological analysis

Objectives: Due to the lack of existing literature, the current research explored experiences of same-sex partner bereavement in women over the age of 60. Method: Semi-structured interviews were conducted with eight women. Transcripts were analysed using interpretative phenomenological analysis. Results: Three themes were identified which elaborated the experiences of older women who had lost a same-sex partner: (1) being left alone encapsulated feelings of isolation and exclusion; (2) navigating visibility centred on how homophobia led to a lack of recognition of the women's grief; and (3) finding new places to be authentic related women's need for new relationships in which they could be themselves. The findings indicate that existing models of partner bereavement may provide useful frameworks when seeking to understand the experiences of older women who have lost their same-sex partners. Conclusion: The findings indicate that in addition to the experiences of partner bereavement noted in research with heterosexual widows, older women who lose same-sex partners may face particular challenges, which can impact upon psychological well-being and adjustment to loss. These challenges appear to result from past and current homophobic and heterosexist attitudes within the UK culture. A range of interventions at individual, group, health service, and societal levels may be beneficial in improving the psychological well-being of older women who lose a same-sex partner

Deciphering chemotaxis pathways using cross species comparisons

<p>Abstract</p> <p>Background</p> <p>Chemotaxis is the process by which motile bacteria sense their chemical environment and move towards more favourable conditions. <it>Escherichia coli </it>utilises a single sensory pathway, but little is known about signalling pathways in species with more complex systems.</p> <p>Results</p> <p>To investigate whether chemotaxis pathways in other bacteria follow the <it>E. coli </it>paradigm, we analysed 206 species encoding at least 1 homologue of each of the 5 core chemotaxis proteins (CheA, CheB, CheR, CheW and CheY). 61 species encode more than one of all of these 5 proteins, suggesting they have multiple chemotaxis pathways. Operon information is not available for most bacteria, so we developed a novel statistical approach to cluster <it>che </it>genes into putative operons. Using operon-based models, we reconstructed putative chemotaxis pathways for all 206 species. We show that <it>cheA-cheW </it>and <it>cheR-cheB </it>have strong preferences to occur in the same operon as two-gene blocks, which may reflect a functional requirement for co-transcription. However, other <it>che </it>genes, most notably <it>cheY</it>, are more dispersed on the genome. Comparison of our operons with shuffled equivalents demonstrates that specific patterns of genomic location may be a determining factor for the observed <it>in vivo </it>chemotaxis pathways.</p> <p>We then examined the chemotaxis pathways of <it>Rhodobacter sphaeroides</it>. Here, the PpfA protein is known to be critical for correct partitioning of proteins in the cytoplasmically-localised pathway. We found <it>ppfA </it>in <it>che </it>operons of many species, suggesting that partitioning of cytoplasmic Che protein clusters is common. We also examined the apparently non-typical chemotaxis components, CheA3, CheA4 and CheY6. We found that though variants of CheA proteins are rare, the CheY6 variant may be a common type of CheY, with a significantly disordered C-terminal region which may be functionally significant.</p> <p>Conclusions</p> <p>We find that many bacterial species potentially have multiple chemotaxis pathways, with grouping of <it>che </it>genes into operons likely to be a major factor in keeping signalling pathways distinct. Gene order is highly conserved with <it>cheA-cheW </it>and <it>cheR-cheB </it>blocks, perhaps reflecting functional linkage. CheY behaves differently to other Che proteins, both in its genomic location and its putative protein interactions, which should be considered when modelling chemotaxis pathways.</p

Non-heterosexual women's experiences of informal social support:a qualitative metasynthesis

This metasynthesis explores how non-heterosexual women experience informal social support. A systematic literature search was conducted to identify papers for inclusion, following which Noblit and Hare's (1988) meta-ethnographic approach was adopted to synthesise the findings of 16 papers. Four themes were derived: (i) disconnection from family life, (ii) the benefits of cross-sexual orientation friendships (iii) negotiating (internalised) homophobia and seeking a space for authenticity, and (iv) the intimacy of friendships between women. The impact of heterosexism on the women’s experiences of social support is discussed, implications for health and social care are explored and future research avenues are proposed

Bioinformatic characterisation of the effector repertoire of the strawberry pathogen Phytophthora cactorum

The oomycete pathogen Phytophthora cactorum causes crown rot, a major disease of cultivated strawberry. We report the draft genome of P. cactorum isolate 10300, isolated from symptomatic Fragaria x ananassa tissue. Our analysis revealed that there are a large number of genes encoding putative secreted effectors in the genome, including nearly 200 RxLR domain containing effectors, 77 Crinklers (CRN) grouped into 38 families, and numerous apoplastic effectors, such as phytotoxins (PcF proteins) and necrosis inducing proteins. As in other Phytophthora species, the genomic environment of many RxLR and CRN genes differed from core eukaryotic genes, a hallmark of the two-speed genome. We found genes homologous to known Phytophthora infestans avirulence genes including Avr1, Avr3b, Avr4, Avrblb1 and AvrSmira2 indicating effector sequence conservation between Phytophthora species of clade 1a and clade 1c. The reported P. cactorum genome sequence and associated annotations represent a comprehensive resource for avirulence gene discovery in other Phytophthora species from clade 1 and, will facilitate effector informed breeding strategies in other crops

Enhancing the Behaviour Change Wheel with synthesis, stakeholder involvement and decision-making: a case example using the 'Enhancing the Quality of Psychological Interventions Delivered by Telephone' (EQUITy) research programme.

From Europe PMC via Jisc Publications RouterHistory: ppub 2021-05-01, epub 2021-05-14Publication status: PublishedFunder: Programme Grants for Applied Research; Grant(s): RP-PG-1016-20010BackgroundUsing frameworks such as the Behaviour Change Wheel to develop behaviour change interventions can be challenging because judgement is needed at various points in the process and it is not always clear how uncertainties can be resolved. We propose a transparent and systematic three-phase process to transition from a research evidence base to a behaviour change intervention. The three phases entail evidence synthesis, stakeholder involvement and decision-making. We present the systematic development of an intervention to enhance the quality of psychological treatment delivered by telephone, as a worked example of this process.MethodIn phase 1 (evidence synthesis), we propose that the capabilities (C), opportunities (O) and motivations (M) model of behaviour change (COM-B) can be used to support the synthesis of a varied corpus of empirical evidence and to identify domains to be included in a proposed behaviour change intervention. In phase 2 (stakeholder involvement), we propose that formal consensus procedures (e.g. the RAND Health/University of California-Los Angeles Appropriateness Methodology) can be used to facilitate discussions of proposed domains with stakeholder groups. In phase 3 (decision-making), we propose that behavioural scientists identify (with public/patient input) intervention functions and behaviour change techniques using the acceptability, practicability, effectiveness/cost-effectiveness, affordability, safety/side-effects and equity (APEASE) criteria.ResultsThe COM-B model was a useful tool that allowed a multidisciplinary research team, many of whom had no prior knowledge of behavioural science, to synthesise effectively a varied corpus of evidence (phase 1: evidence synthesis). The RAND Health/University of California-Los Angeles Appropriateness Methodology provided a transparent means of involving stakeholders (patients, practitioners and key informants in the present example), a structured way in which they could identify which of 93 domains identified in phase 1 were essential for inclusion in the intervention (phase 2: stakeholder involvement). Phase 3 (decision-making) was able to draw on existing Behaviour Change Wheel resources to revisit phases 1 and 2 and facilitate agreement among behavioural scientists on the final intervention modules. Behaviour changes were required at service, practitioner, patient and community levels.ConclusionFrameworks offer a foundation for intervention development but require additional elucidation at each stage of the process. The decisions adopted in this study are designed to provide an example on how to resolve challenges while designing a behaviour change intervention. We propose a three-phase process, which represents a transparent and systematic framework for developing behaviour change interventions in any setting

Determining the stress biomarker profile in patients undergoing total knee replacement and the relationship with outcome at 12 months

Background: Total knee replacement (TKR) is the commonest joint arthroplasty procedure worldwide. Despite excellent outcomes, some studies have reported dissatisfaction in up to 20% of patients. There is evidence of an association between the biochemical stress response to surgery and outcomes. The objective of this study is to describe the stress biomarker profile for TKR, and correlate this with patient outcomes. Methods: A prospective cohort study of 50 patients undergoing primary TKR was conducted. Serum IL-6, TNF-α, neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) were measured immediately pre- and post-operatively, and on Days 1 and 3. Follow-up questionnaires including the Oxford Knee Score (OKS) and EuroQol five dimensions (EQ-5D) were completed at 12-months. Univariate analysis was completed using a linear regression model (p < 0.05). Results: Serum IL-6, NLR, and PLR all increased to Day 1 post-operatively, and decreased by Day 3. TNF-α values increased across all time points. Statistical analysis found a significant negative correlation (r = − 0.414; p = 0.005) between pre-operative IL-6 and 12-month OKS. There was a significant positive correlation between pre-operative NLR and 12 month OKS (r = 0.272; p = 0.039) and 12 month EQ5D (r = 0.268; p = 0.043). Conclusion: This is the first study to describe the biochemical stress response to TKR. The results raise the potential for a pre-operative risk stratification tool for patients based on IL-6 and NLR measurements. Further research should be conducted to explore the underlying mechanisms involved, and investigate interventions to reduce pre-operative physiological stress with a view to improving post-operative outcomes

Comparative analysis of host-associated variation in phytophthora cactorum

Phytophthora cactorum is often described as a generalist pathogen, with isolates causing disease in a range of plant species. It is the causative agent of two diseases in the cultivated strawberry, crown rot (CR; causing whole plant collapse) and leather rot (LR; affecting the fruit). In the cultivated apple, P. cactorum causes girdling bark rots on the scion (collar rot) and rootstock (crown rot), as well as necrosis of the fine root system (root rot) and fruit rots. We investigated evidence for host specialisation within P. cactorum through comparative genomic analysis of 18 isolates. Whole genome phylogenetic analysis provided genomic support for discrete lineages within P. cactorum, with well-supported non-recombining clades for strawberry CR and apple infecting isolates specialised to strawberry crowns and apple tissue. Isolates of strawberry CR are genetically similar globally, while there is more diversity in apple-infecting isolates. We sought to identify the genetic basis of host specialisation, demonstrating gain and loss of effector complements within the P. cactorum phylogeny, representing putative determinants of host boundaries. Transcriptomic analysis highlighted that those effectors found to be specific to a single host or expanded in the strawberry lineage are amongst those most highly expressed during infection of strawberry and give a wider insight into the key effectors active during strawberry infection. Many effectors that had homologues in other Phytophthoras that have been characterised as avirulence genes were present but not expressed in our tested isolate. Our results highlight several RxLR-containing effectors that warrant further investigation to determine whether they are indeed virulence factors and host-specificity determinants for strawberry and apple. Furthermore, additional work is required to determine whether these effectors are suitable targets to focus attention on for future resistance breeding efforts
