Reducing inequalities by supporting individuals to make informed decisions about accepting their breast screening invitations.

OBJECTIVES: Individuals from deprived areas are less likely to attend breast screening. Inequalities in the coverage of breast screening are associated with poorer cancer outcomes. Individuals who have a positive first experience are more likely to attend subsequent mammograms. This work evaluates the provision of an additional telephone call to individuals who have never attended breast screening, to establish whether this increases attendance. SETTING AND METHODS: 1423 patients from four general practitioner practices within socially deprived areas of National Health Service Tayside (UK) comprised the study population. In addition to their standard appointment letter, individuals were to receive a call at least 24 h prior to their appointment. The call identified barriers to screening, and offered a supportive, problem-solving approach to overcoming these barriers. Data collected included: age, Scottish Index of Multiple Deprivation, first-time invite or previous non-attender, if contactable, duration of call, number of days prior to appointment, and confirmation appointment letter was received. The primary outcome was attendance at the screening. RESULTS: Contact by phone was made with 678 (47.6%) of the study population. Of those, 483 (71.2%) attended their appointment, 122 (18%) cancelled and 73 (10.8%) did not attend (DNA), versus 344 (46.2%) attending, 34 (4.6%) cancelling and 367 (49.3%) not attending among those who were not able to be contacted. Those who received a call were more likely to attend their appointment and less likely to DNA compared to individuals not receiving the call. CONCLUSION: The intervention is simple and low cost; results indicate that the additional call may increase attendance and reduce DNA appointments at breast screening.

Integrating a virtual reality relaxation clinic within acute psychiatric services: A pilot study.

People with acute psychiatric conditions experience heightened stress, which is associated with worsened symptoms and increased violence on psychiatric wards. Traditional stress management techniques can be challenging for patients. Virtual reality (VR) relaxation appears promising to reduce stress; however, research on VR for psychiatric wards is limited. This mixed-methods study investigated feasibility and acceptability of integrating a VR relaxation clinic within acute psychiatric services. The study evaluated a VR relaxation session for inpatients and outpatients with acute psychiatric conditions (N = 42) and therapists' (N = 6) experience facilitating VR sessions for patients. Self-report assessments of psychological wellbeing were completed by patients pre- and post-VR. Patients and therapists provided qualitative feedback. The number of violent incidents and restrictive practices on the wards in the 12 weeks before VR implementation was compared to the first 12 weeks of VR. Post-VR, there were statistically significant increases in patients' relaxation, happiness, and connectedness to nature, and decreases in stress, anxiety, and sadness. Qualitative findings indicate patients found sessions enjoyable, relaxing, and helpful. Therapists provided positive feedback but highlighted practical challenges. Violent incidents and restrictive practices halved during VR implementation. VR relaxation appears feasible and acceptable in acute services. Larger studies should evaluate potential impact on psychiatric wards.

Videoconference-based Creativity Workshops for mental health staff during the COVID-19 pandemic.

BACKGROUND: COVID-19 presented significant challenges to psychiatric staff, while social distancing and remote working necessitated digital communications. NHS England prioritised staff wellbeing. Arts-based creativity interventions appear to improve psychological wellbeing, so this study evaluated online Creativity Workshops as a staff support response for COVID-19-related stress. METHODS: Participants were staff from a South London NHS psychiatric hospital. Group Creativity Workshops were facilitated via Microsoft Teams. Acceptability data on pre- and post-workshop mood and attitudes were self-reported by participants. Feasibility data were gathered from adherence to number of workshop components delivered. RESULTS: Eight workshops were delivered in May-September 2020 (N = 55) with high adherence to components. Participants reported significantly increased positive mood and attitudes towards themselves and others; and decreased stress and anxiety. CONCLUSIONS: Online Creativity Workshops appear feasible and acceptable in reducing stress in psychiatric staff. Integrating a programme of Creativity Workshops within healthcare staff support may benefit staff wellbeing.

Stroke survivors' perceptions of their sedentary behaviours three months after stroke.

PURPOSE: Sedentary behaviour is any waking behaviour in sitting, lying or reclining postures with low energy expenditure. High sedentary behaviour levels, common after stroke, are associated with poor health and higher levels of mobility disability. The aim of this study was to undertake a behavioural diagnosis of sedentary behaviour in the early phase after stroke to inform interventions that may reduce sedentary behaviour and associated disability. METHODS AND MATERIALS: Independently mobile stroke survivors were interviewed three months after stroke. The topic guide was informed by the central layer of the Behaviour Change Wheel to explore three components: capability, opportunity and motivation. This model recognises that behaviour is the consequence of an interacting system of these components. Interviews were transcribed verbatim and analysed using The Framework Method. RESULTS: Thirty one people were interviewed (66.7 years; 16 male). The perception of diminished capability to reduce sedentary behaviour due to physical tiredness/fatigue, and pain/discomfort acting as both a motivator and inhibitor to movement, were discussed. Environmental barriers and the importance of social interaction were highlighted. Perceived motivation to reduce sedentary behaviour was influenced by enjoyment of sedentary behaviours, fear of falling and habitual nature of sedentary behaviours. CONCLUSIONS: This information will inform evidence-based sedentary behaviour interventions after stroke.Implications for rehabilitationHigher levels of sedentary behaviours are associated with poor health and stroke survivors are highly sedentary.Stroke survivors have complex reasons for spending time in sedentary behaviours including fatigue, pain, fear of falling and environmental barriers.Future interventions should educate stroke survivors on the health consequences of sedentary behaviours and encourage an increased awareness of time spent sedentary.Supporting stroke survivors to identify enjoyable and achievable activities that involve standing and movement, and ideally social interaction, is recommended.

Breast cancer stromal clotting activation (Tissue Factor and thrombin): A pre-invasive phenomena that is prognostic in invasion.

BACKGROUND: Tumor stroma, of which fibroblasts are the most abundant cell, resembles a non-healing wound, where a procoagulant environment creates a permissive milieu for cancer growth. We aimed to determine if tumor expression of coagulation factors (procoagulant phenotype), and systemic hypercoagulability, occur at the preinvasive (ductal carcinoma in situ; DCIS) stage and correlate with breast cancer subtype, disease-free survival (DFS), and overall survival (OS). METHODS: In a prospective cohort of early breast cancer (DCIS, n = 76; invasive, n = 248) tumor, normal breast and plasma were examined. Fibroblast and epithelial expression of Tissue Factor (TF), thrombin, PAR1, PAR2, and plasma thrombin-antithrombin (TAT) and D-dimer were correlated with clinicopathological data, and 5-year survival. RESULTS: Fibroblast expression of TF, thrombin, and PAR1 was increased in DCIS and invasive cancer compared to normal breast fibroblasts (P ≤ .003, all). Fibroblast TF, thrombin, PAR1, and PAR2 was increased in cancers with high Ki67, high grade, ER- (vs ER+), and HER2+ (vs HER2-) (all P < .05). On univariate analysis, fibroblast TF expression was inversely associated with DFS (P = .04) and OS (P = .02). D-dimer was higher in node positive (507 (CI: 411-625) ng/mL, n = 68) vs negative patients (428 (CI: 387-472) ng/mL, n = 171, P = .004) and inversely associated with OS (P = .047). On multivariate analysis, plasma TAT was associated with reduced OS (HR 3.26, CI 1.16-3.1, P = .02), with a high plasma TAT (≥3.2 ng/mL) associated with > 3-fold mortality risk compared to low TAT. CONCLUSION: This demonstrates procoagulant phenotypic changes occur in fibroblasts at the preinvasive stage. Fibroblast procoagulant phenotype is associated with aggressive breast cancer subtypes and reduced survival. Coagulation may be a therapeutic target in breast cancer.

A qualitative theory guided analysis of stroke survivors' perceived barriers and facilitators to physical activity.

PURPOSE: After stroke, physical activity and physical fitness levels are low, impacting on health, activity and participation. It is unclear how best to support stroke survivors to increase physical activity. Little is known about the barriers and facilitators to physical activity after stroke. Thus, our aim was to explore stroke survivors' perceived barriers and facilitators to physical activity. METHODS: Semi-structured interviews with 13 ambulatory stroke survivors exploring perceived barriers and facilitators to physical activity post stroke were conducted in participants' homes, audio-recorded and transcribed verbatim. The Theoretical Domains Framework (TDF) informed content analysis of the interview transcripts. RESULTS: Data saturation was reached after interviews with 13 participants (median age of 76 years (inter-quartile range (IQR) = 69-83 years). The median time since stroke was 345 d (IQR = 316-366 d). The most commonly reported TDF domains were "beliefs about capabilities", "environmental context and resources" and "social influence". The most commonly reported perceived motivators were: social interaction, beliefs of benefits of exercise, high self-efficacy and the necessity of routine behaviours. The most commonly reported perceived barriers were: lack of professional support on discharge from hospital and follow-up, transport issues to structured classes/interventions, lack of control and negative affect. CONCLUSIONS: Stroke survivors perceive several different barriers and facilitators to physical activity. Stroke services need to address barriers to physical activity and to build on facilitators to promote physical activity after stroke. IMPLICATIONS FOR REHABILITATION: Physical activity post stroke can improve physical fitness and function, yet physical activity remains low among stroke survivors. Understanding stroke survivors' perceived barriers and facilitators to physical activity is essential to develop targeted interventions to increase physical activity. Beliefs about capabilities, environmental context and resources and social influences were the mostly commonly report influences on stroke survivors' perceived barriers and facilitators to physical activity.

Characterization of a population of neural progenitor cells in the infant hippocampus.

AIMS: Abnormalities of the hippocampus are associated with a range of diseases in children, including epilepsy and sudden death. A population of rod cells in part of the hippocampus, the polymorphic layer of the dentate gyrus, has long been recognized in infants. Previous work suggested that these cells were microglia and that their presence was associated with chronic illness and sudden infant death syndrome. Prompted by the observations that a sensitive immunohistochemical marker of microglia used in diagnostic practice does not typically stain these cells and that the hippocampus is a site of postnatal neurogenesis, we hypothesized that this transient population of cells were not microglia but neural progenitors. METHODS: Using archived post mortem tissue, we applied a broad panel of antibodies to establish the immunophenotype of these cells in 40 infants dying suddenly of causes that were either explained or remained unexplained, following post mortem investigation. RESULTS: The rod cells were consistently negative for the microglial markers CD45, CD68 and HLA-DR. The cells were positive, in varying proportions, for the neural progenitor marker, doublecortin, the neural stem cell marker, nestin and the neural marker, TUJ1. CONCLUSIONS: These data support our hypothesis that the rod cells of the polymorphic layer of the dentate gyrus in the infant hippocampus are not microglia but a population of neural progenitors. These findings advance our understanding of postnatal neurogenesis in the human hippocampus in health and disease and are of diagnostic importance, allowing reactive microglia to be distinguished from the normal population of neural progenitors.

mTOR-dependent abnormalities in autophagy characterize human malformations of cortical development: evidence from focal cortical dysplasia and tuberous sclerosis.

Focal cortical dysplasia (FCD) is a localized malformation of cortical development and is the commonest cause of severe childhood epilepsy in surgical practice. Children with FCD are severely disabled by their epilepsy, presenting with frequent seizures early in life. The commonest form of FCD in children is characterized by the presence of an abnormal population of cells, known as balloon cells. Similar pathological changes are seen in the cortical malformations that characterize patients with tuberous sclerosis complex (TSC). However, the cellular and molecular mechanisms that underlie the malformations of FCD and TSC are not well understood. We provide evidence for a defect in autophagy in FCD and TSC. We have found that balloon cells contain vacuoles that include components of the autophagy pathway. Specifically, we show that balloon cells contain prominent lysosomes by electron microscopy, immunohistochemistry for LAMP1 and LAMP2, LysoTracker labelling and enzyme histochemistry for acid phosphatase. Furthermore, we found that balloon cells contain components of the ATG pathway and that there is cytoplasmic accumulation of the regulator of autophagy, DOR. Most importantly we found that there is abnormal accumulation of the autophagy cargo protein, p62. We show that this defect in autophagy can be, in part, reversed in vitro by inhibition of the mammalian target of rapamycin (mTOR) suggesting that abnormal activation of mTOR may contribute directly to a defect in autophagy in FCD and TSC.
