Abstract
OBJECTIVE To develop a theory-informed behaviour change intervention to promote appropriate hospital antibiotic use, guided by the Medical Research Council's complex interventions framework. METHODS A phased approach was used, including triangulation of data from meta-ethnography and two qualitative studies. Central to intervention design was the generation of a robust theoretical basis using the Behaviour Change Wheel to identify relevant determinants of behaviour change and intervention components. Intervention content was guided by APEASE (Acceptability, Practicability, Effectiveness, Affordability, Side-effects, and Equity) criteria and coded using a Behaviour Change Technique Taxonomy. Stakeholders were involved throughout. RESULTS From numerous modifiable prescribing behaviours identified, active 'antibiotic time-out' was selected as the target behaviour to help clinicians safely initiate antibiotic reassessment. Prescribers' capability, opportunity, and motivation were potential drivers for changing this behaviour. The design process resulted in the selection of 25 behaviour change techniques subsequently translated into intervention content. Integral to this work was the development and refinement of a Digital Antibiotic Review Tracking Toolkit. CONCLUSION This novel work demonstrates how the Behaviour Change Wheel can be used with the Medical Research Council framework to develop a theory-based behaviour change intervention targeting barriers to timely hospital antibiotic reassessment. Future research will evaluate the Antibiotic Toolkit's feasibility and effectiveness.

Introduction
Despite major attempts aiming to revascularize an ischemic heart, prognosis of cardiac ischemia remains poor. A major obstacle for the induction of new blood vessels, referred as therapeutic angiogenesis, is inefficient gene transfer in cardiac endothelial cells (ECs). This poor permissiveness to genetic modification is a limiting step in studies of pathological conditions with inadequate, but also with increased vascularization. To study the function of a specific gene and its potential implications in angiogenesis, the most straightforward approach would be to either overexpress or silence it in ECs. We and others have tested multiple protocols for either transfection and transduction of primary ECs in vitro and in vivo, with no success. Vectors based on Adeno-associated virus (AAV) and Lentivirus (LV) stand as ideal tools for gene delivery, however they do not work in cardiac ECs.
Purpose
To enhance the permissiveness of EC, we optimized and performed high-throughput screening on adult cardiac ECs using a library of FDA approved drugs, to search for compounds increasing transduction by AAV6 and LV, with the final aim to identify the major determinants inhibiting genetic modification of ECs.
Methods
Cardiac ECs were isolated from 2 months old C57BL/6 mice and plated on 384-well plates. After 48 hours, the FDA drug library (> 1500 compounds) was added together with AAV6-dsRed and LV-GFP. Cells were fixed with 4% PFA 72 hours post-transduction, and subsequently stained for the EC marker ERG. The levels of AAV6-dsRed, LV-GFP and ERG expression were assessed by automated, high-content microscopy.
Results
After two rounds of screening at different drug concentrations, we obtained a list of candidate compounds able to increase adult cardiac EC transduction by either AAV6 or LV over two folds. Among these, our best hit increasing AAV6-mediated transduction was Vatalanib, a tyrosine kinase inhibitor acting on VEGFRs, PDGFR, and c-Kit. Valatanib not only increased permissiveness to AAV6, but it also changed the morphology of the cells, which became elongated and similar to mesenchymal cells. This suggested ongoing endothelial mesenchymal transition (EndMT), which was verified by decreased CD31 and increased α-SMA expression. Interestingly, AAV mostly transduced cells with the lowest CD31 expression.
Conclusions
Our high-throughput screening identified Vatalanib as the most potent drug in increasing permissiveness of cardiac ECs to AAV transduction. Because the drug induced loss of CD31 and gain in α-SMA, we hypothesized that the reason for increased permissiveness was EndMT. This hypothesis is consistent with the known mechanism of action of Valatanib, which inhibits VEGFR2 and thus interferes with VEGF signalling, that in turn is essential to maintain EC identity.

Introduction
With the increased prevalence of chronic diseases, non-healing wounds place a significant burden on the health system, with a prevalence of 2-5%, similar to the one of heart failure. They are persistent full-thickness skin lesions that affect patients suffering from vascular disorders, such as diabetes and peripheral artery disease. Skin implants and substitutes are currently applied to promote the closure of non-healing wounds. However, both approaches are poorly effective because of lack of appropriate vascularization.
Purpose
To promote the neo-vascularization of non-healing wounds, we use Stromal Vascular Fraction (SVF) as innovative therapeutic opportunity for wound treatment.
Here, we aim to 1) characterize and demonstrate the pro-angiogenic role of SVF cells and 2) provide pre-clinical evidence of the therapeutic efficacy of the human SVF in promoting the neo-vascularization in a new mouse model of ischemic, non-healing wound.
Methods
To assess capacity of SVF-derived cells to improve wound revascularization, we created a new model of non-healing wound generated by wounding an ischemic limb in mice. Human and mouse SVF was purified from adipose tissue and seeded on a clinical-grade skin substitute prior to its implantation on the ischemic wound of a recipient animal. The transplantation of human SVF into NSG immunodeficient mice was verified using species-specific antibodies, while the use of genetically modified mice allowed us to trace the fate of both endothelial and non-endothelial cells upon their transplantation into syngeneic recipient animals. The function of SVF-induced vessels was assessed by systemic injection of biotinylated lectin and by Single Photon Emission Tomography (SPECT) of the treated limb.
Results
At day 7 the implanted mouse SVF gives rise to a widespread vascular network composed by arteries, capillaries, veins, as well as lymphatic vessels. Similarly, human SVF-derived endothelial cells formed hybrid human-mouse vessels that were stabilized by perivascular cells. At both histological and functional analysis, these vessels were connected with the host circulatory system and determined a 2-fold increase in tissue perfusion. The comparison of the activity of human SVF from different donors allowed us to disclose its dual mechanisms of action.
Conclusions
Here we demonstrated the efficacy of the SVF in promoting neo-vascularization of a skin substitute in a mouse model of ischemic, non-healing wounds. Its therapeutic efficacy relies on dual mechanisms of action. On the one hand, SVF-derived ECs engraft and expand, directly forming new vascular units that colonize the scaffold and extend into surrounding tissues. On the other hand, the mesenchymal progenitors stimulate the expansion of the host vasculature, which extends into the scaffold, with the eventual appearance of donor-host hybrid vessels.
Collectively, these data support the use of human SVF as a powerful cell therapy to treat non-healing wounds.

Abstract
As mediators of intercellular communication, extracellular vesicles containing molecular cargo such as microRNAs, are secreted by cells and taken up by recipient cells to influence their cellular phenotype and function. Here, we report that cardiac stress-induced differential microRNA content, with miR-200c-3p being one of the most enriched, in cardiomyocyte-derived extracellular vesicles mediates functional crosstalk with endothelial cells. Silencing of miR-200c-3p in mice subjected to chronic increased cardiac pressure overload resulted in attenuated hypertrophy, smaller fibrotic areas, higher capillary density and preserved cardiac ejection fraction. Interestingly, we were able to maximal rescue microvascular and cardiac function with very low doses of antagomir, which specifically silences miR-200c-3p expression in the non-myocyte cells. Our results reveal vesicle transfer of miR-200c-3p from cardiomyocytes to cardiac endothelial cells, underlining the importance of cardiac intercellular communication in the pathophysiology of heart failure.

Abstract
The research of the last two decades has defined a crucial role of cellular senescence in both the physiology and pathology of skin, and senescent cells have been detected in conditions including development, regeneration, aging, and disease. The pathophysiology of cellular senescence in skin is complex as the phenotype of senescence pertains to several different cell types including fibroblasts, keratinocytes and melanocytes, among others. Paradoxically, the transient presence of senescent cells is believed to be beneficial in the context of development and wound healing, while the chronic presence of senescent cells is detrimental in the context of aging, diseases, and chronic wounds, which afflict predominantly the elderly. Identifying strategies to prevent senescence induction or reduce senescent burden in the skin could broadly benefit the aging population. Senolytics, drugs known to specifically eliminate senescent cells while preserving non-senescent cells, are being intensively studied for use in the clinical setting. Here, we review recent research on skin senescence, on the methods for the detection of senescent cells and describe promises and challenges related to the application of senolytic drugs. This article is part of the Special Issue - Senolytics - Edited by Joao Passos and Diana Jurk.

Abstract
Cardiovascular toxicity remains one of the most adverse side effects in cancer patients receiving chemotherapy. Extra-virgin olive oil (EVOO) is rich in cancer preventive polyphenols endowed with anti-inflammatory, anti-oxidant activities which could exert protective effects on heart cells. One very interesting derivative of EVOO preparation is represented by purified extracts from olive mill waste waters (OMWW) rich in polyphenols. Here, we have investigated the anti-cancer activity of a OMWW preparation, named A009, when combined with chemotherapeutics, as well as its potential cardioprotective activities. Mice bearing prostate cancer (PCa) xenografts were treated with cisplatin, alone or in combination with A009. In an in vivo model, we found synergisms of A009 and cisplatin in reduction of prostate cancer tumor weight. Hearts of mice were analyzed, and the mitochondria were studied by transmission electron microscopy. The hearts of mice co-treated with A009 extracts along with cisplatin had reduced mitochondria damage compared to the those treated with chemotherapy alone, indicating a cardioprotective role. To confirm the in vivo results, tumor cell lines and rat cardiomyocytes were treated with cisplatin in vitro, with and without A009. Another frequently used chemotherapeutic agent 5-fluorouracil (5-FU), was also tested in this assay, observing a similar effect. In vitro, the combination of A009 with cisplatin or 5-FU was effective in decreasing prostate and colon cancer cell growth, while it did not further reduce growth of rat cardiomyocytes also treated with cisplatin or 5-FU. A009 cardioprotective effects towards side effects caused by 5-FU chemotherapy were further investigated, using cardiomyocytes freshly isolated from mice pups. A009 mitigated toxicity of 5-FU on primary cultures of mouse cardiomyocytes. Our study demonstrates that the polyphenol rich purified A009 extracts enhance the effect of chemotherapy in vitro and in vivo, but mitigates chemotherpy adverse effects on heart and on isolated cardiomyocytes. Olive mill waste water extracts could therefore represent a potential candidate for cardiovascular prevention in patients undergoing cancer chemotherapy.

Abstract
Rationale Alveolar type II (ATII) cells act as adult stem cells contributing to alveolar type I (ATI) cell renewal and play a major role in idiopathic pulmonary fibrosis (IPF), as supported by familial cases harbouring mutations in genes specifically expressed by these cells. During IPF, ATII cells lose their regenerative potential and aberrantly express pathways contributing to epithelial–mesenchymal transition (EMT). The microRNA miR-200 family is downregulated in IPF, but its effect on human IPF ATII cells remains unproven. We wanted to 1) evaluate the characteristics and transdifferentiating ability of IPF ATII cells, and 2) test whether miR-200 family members can rescue the regenerative potential of fibrotic ATII cells. Methods ATII cells were isolated from control or IPF lungs and cultured in conditions promoting their transdifferentiation into ATI cells. Cells were either phenotypically monitored over time or transfected with miR-200 family members to evaluate the microRNA effect on the expression of transdifferentiation, senescence and EMT markers. Results IPF ATII cells show a senescent phenotype (p16 and p21), overexpression of EMT (ZEB1/2) and impaired expression of ATI cell markers (AQP5 and HOPX) after 6 days of culture in differentiating medium. Transfection with certain miR-200 family members (particularly miR-200b-3p and miR-200c-3p) reduced senescence marker expression and restored the ability to transdifferentiate into ATI cells. Conclusions We demonstrated that ATII cells from IPF patients express senescence and EMT markers, and display a reduced ability to transdifferentiate into ATI cells. Transfection with certain miR-200 family members rescues this phenotype, reducing senescence and restoring transdifferentiation marker expression. Idiopathic pulmonary fibrosis alveolar epithelial type II cells show senescence and EMT features, but miR-200b and miR-200c can restore the ability of type II cells to transdifferentiate in vitro into type I alveolar epithelial cellshttp://bit.ly/359tlit

Abstract
Fibrosis is a hallmark in the pathogenesis of various diseases, with very limited therapeutic solutions. A key event in the fibrotic process is the expression of contractile proteins, including α-smooth muscle actin (αSMA) by fibroblasts, which become myofibroblasts. Here, we report the results of a high-throughput screening of a library of approved drugs that led to the discovery of haloperidol, a common antipsychotic drug, as a potent inhibitor of myofibroblast activation. We show that haloperidol exerts its antifibrotic effect on primary murine and human fibroblasts by binding to sigma receptor 1, independent from the canonical transforming growth factor-β signaling pathway. Its mechanism of action involves the modulation of intracellular calcium, with moderate induction of endoplasmic reticulum stress response, which in turn abrogates Notch1 signaling and the consequent expression of its targets, including αSMA. Importantly, haloperidol also reduced the fibrotic burden in 3 different animal models of lung, cardiac, and tumor-associated fibrosis, thus supporting the repurposing of this drug for the treatment of fibrotic conditions.

Abstract
Background Late-onset Pompe disease (LOPD) is a recessive disease caused by α-glucosidase (GAA) deficiency, leading to progressive muscle weakness and/or respiratory failure in children and adults. Respiratory derangement can be the first indication of LOPD, but the diagnosis may be difficult for pneumologists. We hypothesize that assessing the GAA activity in suspected patients by a dried blood spot (DBS) may help the diagnosis of LOPD in the pneumological setting. Population and methods We performed a multicenter DBS survey of patients with suspected LOPD according to a predefined clinical algorithm. From February 2015 to December 2017, 140 patients (57 ± 16 yrs., 80 males) were recruited in 19 Italian pneumological units. The DBS test was performed by a drop of blood collected on absorbent paper. Patients with GAA activity < 2.6 μmol/L/h were considered positive. A second DBS test was performed in the patients positive to the first assay. Patients testing positive at the re-test underwent a skeletal muscle biopsy to determine the GAA enzymatic activity. Results 75 recruited subjects had outpatient access, 65 subjects were admitted for an acute respiratory failure episode. Two patients tested positive in both the first and second DBS test (1.4% prevalence), and the LOPD diagnosis was confirmed through histology, with patients demonstrating a deficient GAA muscle activity (3.6 and 9.1 pmol/min/mg). A further five subjects were positive in the first DBS test but were not confirmed at re-test. The two positive cases were both diagnosed after hospitalization for acute respiratory failure and need of noninvasive ventilation. Most of the recruited patients had reduced maximal respiratory pressures (MIP 50 ± 27% and MEP 55 ± 27% predicted), restrictive pattern (FEV1/FVC 81.3 ± 13.6) and hypoxaemia (PaO2 70.9 ± 14.5 mmHg). Respiratory symptoms were present in all the patients, but only 48.6% of them showed muscle weakness in the pelvic girdle and/or in the scapular girdle (35.7%). Conclusions DBS GAA activity test may be a powerful screening tool among pneumologists, particularly in the acute setting. A simple clinical algorithm may aid in the selection of patients on which to administer the DBS test.

Abstract
Background Designing and implementing high-quality health care services and interventions requires robustly synthesised evidence. Syntheses of qualitative research studies can provide evidence of patients’ experiences of health conditions; intervention feasibility, appropriateness and acceptability to patients; and advance understanding of health care issues. The unique, interpretive, theory-based meta-ethnography synthesis approach is suited to conveying patients’ views and developing theory to inform service design and delivery. However, meta-ethnography reporting is often poor quality, which discourages trust in, and use of, meta-ethnography findings. Users of evidence syntheses require reports that clearly articulate analytical processes and findings. Tailored research reporting guidelines can raise reporting standards but none exists for meta-ethnography. This study aims to create an evidence-based meta-ethnography reporting guideline articulating the methodological standards and depth of reporting required to improve reporting quality. Methods/design The mixed-methods design of this National Institute of Health Research-funded study (http://www.stir.ac.uk/emerge/) follows good practice in research reporting guideline development comprising: (1) a methodological systematic review (PROSPERO registration: CRD42015024709) to identify recommendations and guidance in conducting/reporting meta-ethnography; (2) a review and audit of published meta-ethnographies to identify good practice principles and develop standards in conduct/reporting; (3) an online workshop and Delphi studies to agree guideline content with 45 international qualitative synthesis experts and 45 other stakeholders including patients; (4) development and wide dissemination of the guideline and its accompanying detailed explanatory document, a report template for National Institute of Health Research commissioned meta-ethnographies, and training materials on guideline use. Discussion Meta-ethnography, devised in the field of education, is now used widely in other disciplines. Methodological advances relevant to meta-ethnography conduct exist. The extent of discipline-specific adaptations of meta-ethnography and the fit of any adaptions with the underpinning philosophy of meta-ethnography require investigation. Well-reported meta-ethnography findings could inform clinical decision-making. A bespoke meta-ethnography reporting guideline is needed to improve reporting quality, but to be effective potential users must know it exists, trust it and use it. Therefore, a rigorous study has been designed to develop and promote a guideline. By raising reporting quality, the guideline will maximise the likelihood that high-quality meta-ethnographies will contribute robust evidence to improve health care and patient outcomes.

Abstract
BACKGROUND Vascular endothelial growth factor (VEGF)-B activates cytoprotective/antiapoptotic and minimally angiogenic mechanisms via VEGF receptors. Therefore, VEGF-B might be an ideal candidate for the treatment of dilated cardiomyopathy, which displays modest microvascular rarefaction and increased rate of apoptosis. OBJECTIVES This study evaluated VEGF-B gene therapy in a canine model of tachypacing-induced dilated cardiomyopathy. METHODS Chronically instrumented dogs underwent cardiac tachypacing for 28 days. Adeno-associated virus serotype 9 viral vectors carrying VEGF-B167 genes were infused intracoronarily at the beginning of the pacing protocol or during compensated heart failure. Moreover, we tested a novel VEGF-B167 transgene controlled by the atrial natriuretic factor promoter. RESULTS Compared with control subjects, VEGF-B167 markedly preserved diastolic and contractile function and attenuated ventricular chamber remodeling, halting the progression from compensated to decompensated heart failure. Atrial natriuretic factor-VEGF-B167 expression was low in normally functioning hearts and stimulated by cardiac pacing; it thus functioned as an ideal therapeutic transgene, active only under pathological conditions. CONCLUSIONS Our results, obtained with a standard technique of interventional cardiology in a clinically relevant animal model, support VEGF-B167 gene transfer as an affordable and effective new therapy for nonischemic heart failure.

Abstract
Key relatives of 30 first or early admission psychotic patients (mainly with a diagnosis of schizophrenia) were interviewed (for a second time) 18 months after participating in an initial assessment of expressed emotion (EE). The patients were followed up throughout the interim period, during which time 17 experienced a psychotic relapse. Although there continued to be a negligible association between initial EE rating (established during the index admission) and relapse, a significant association between EE rating at 18 months and psychiatric status of the patient during the follow-up period emerged. Results are discussed in the context of recent interactional theories of the relationship between household EE and psychiatric morbidity.

Abstract
In a catchment area study of 101 first inceptions of schizophrenia, mania and atypical psychoses, women were significantly more likely to have atypical psychosis and men were more likely to have definite schizophrenia. Negative symptoms such as affective flattening and poverty of speech were already present in many cases, and were significantly increased in patients with definite schizophrenia (geometric mean 5.6) compared with those with atypical psychosis (geometric mean 3.2) and mania (geometric mean 1.5). Negative symptoms were also twice as severe in men (geometric mean 5.5) than women (geometric mean 2.6). There was a significant increase in negative symptom severity with longer illness and greater depression, but the diagnosis and the sex effects were not caused by these factors. We suggest that our findings are further support for the hypothesis that men have a greater biological vulnerability to negative symptoms and consequent social disability in the face of psychosis, particularly a schizophrenic psychosis, and that this may be one explanation for the apparently greater risk of definite schizophrenia and its poorer prognosis in men.

Abstract
The frequency and distribution of negative symptoms in a sample of 40 patients admitted to hospital with RDC-definite schizophrenia were examined. There was a highly significant positive correlation between negative symptom scores obtained using three different rating scales, but the presence of negative symptoms was not significantly related to duration of illness or number of episodes of illness. These findings do not support a model of negative symptoms being the consequence of schizophrenic relapse, but are in favour of their being an integral component of the schizophrenic syndrome, as salient in the first as in later episodes.

Abstract
Key relatives of 33 first or early admission psychotic patients (mainly schizophrenics) were interviewed to determine household levels of expressed emotion (EE). The patients were followed up for 12 months from index admission, during which time 13 (39%) experienced psychotic relapse. There was no association between relapse rate and household EE, but correlations between individual components of EE and pre-morbid measures suggest that level of criticism may be related to less acute onset of index episode, greater elapsed time since first signs of illness, and poor adjustment in the realm of work/study. The results are discussed in the context of continuing uncertainties about the precise nature of the relationship between EE and relapse.

Abstract
Despite increasing interest in negative symptoms in schizophrenia there has been little work on their incidence in early schizophrenia or in other psychoses. This study examined 79 nondepressive psychotics within 2 years of onset of illness, diagnosed by Research Diagnostic Criteria and assessed for negative symptoms using the Scale for the Assessment of Negative Symptoms. Marked negative symptoms were observed in nearly half of patients diagnosed as suffering definite schizophrenia and were rarely found in other psychoses. Negative symptoms were not significantly correlated with positive symptoms, depression or exposure to neuroleptics, but were correlated with developing extrapyramidal side effects.

Abstract
Seventy-eight patients with dermatitis herpetiformis have been followed up for periods ranging from 3 to 14 years (mean 7.4). Forty-two patients were treated with gluten-free diet (GFD) and thirty-six took a normal diet (ND). Thirty of the forty-two (71%) taking the GFD were able to discontinue drugs previously needed to control their rash compared with five (14%) of the thirty-six patients taking a ND. The mean time taken to reduce drug requirements for patients taking a GFD was 8 months (range 4-30), and for stopping drugs, 29 months (range 6-108). The incidence of macroscopic abnormality of the small intestine decreased from 69 to 15%, and the mean intra-epithelial lymphocyte count decreased significantly in those patients taking a GFD, whereas there was no significant change in patients taking a ND. The improvement in the skin and intestinal lesions was related to the strictness of the GFD.

Abstract
Two cases of adult linear IgA disease are reported. They demonstrate the two sites of deposition of IgA at an ultrastructural level: sub-basal lamina and lamina lucida. This finding supports the view that there are subgroups of this disease. Clinical presentation and histological appearance of lesional skin are misleading, and the immunofluorescent appearance is unhelpful in predicting the ultrastructural localization of the IgA deposit.
