Methods Used in Co-Creation Within the Health CASCADE Co-Creation Database and Gray Literature: Systematic Methods Overview.

Background: Co-creation is increasingly recognized for its potential to generate innovative solutions, particularly in addressing complex and wicked problems in public health. Despite this growing recognition, there are no standards or recommendations for method use in co-creation, leading to confusion and inconsistency. While some studies have examined specific methods, a comprehensive overview is lacking, limiting the collective understanding and ability to make informed decisions about the most appropriate methods for different contexts and research objectives.

Navigating process evaluation in co-creation: a Health CASCADE scoping review of used frameworks and assessed components.

Background: Co-creation is seen as a way to ensure all relevant needs and perspectives are included and to increase its potential for beneficial effects and uptake process evaluation is crucial. However, existing process evaluation frameworks have been built on practices characterised by top-down developed and implemented interventions and may be limited in capturing essential elements of co-creation. This study aims to provide a review of studies planning and/or conducting a process evaluation of public health interventions adopting a co-creation approach and aims to derive assessed process evaluation components, used frameworks and insights into formative and/or participatory evaluation.

Real life experience on the use of Remdesivir in patients admitted to COVID-19 in two referral Italian hospital: a propensity score matched analysis.

Remdesivir (RDV) was the first Food and Drug Administration (FDA)-approved medication for COVID-19, with discordant data on efficacy in reducing mortality risk and disease progression. In the context of a dynamic and rapidly changing pandemic landscape, the utilization of real-world evidence is of utmost importance. The objective of this study is to evaluate the impact of RDV on patients who have been admitted to two university referral hospitals in Italy due to COVID-19.

A review of implementation and evaluation frameworks for public health interventions to inform co-creation: a Health CASCADE study.

Background: By including the needs and perspectives of relevant stakeholders, co-creation is seen as a promising approach for tackling complex public health problems. However, recommendations and guidance on how to plan and implement co-creation are lacking. By identifying and analysing existing implementation and evaluation frameworks for public health, this study aims to offer key recommendations for professional stakeholders and researchers wanting to adopt a co-creation approach to public health interventions.

Conducting co-creation for public health in low and middle-income countries: a systematic review and key informant perspectives on implementation barriers and facilitators.

Background: There has been an increase in the use of co-creation for public health because of its claimed potential to increase an intervention's impact, spark change and co-create knowledge. Still, little is reported on its use in low-and-middle-income countries (LMICs). This study offers a comprehensive overview of co-creation used in public-health-related interventions, including the interventions' characteristics, and reported implementation barriers and facilitators.

Establishing a Health CASCADE-Curated Open-Access Database to Consolidate Knowledge About Co-Creation: Novel Artificial Intelligence-Assisted Methodology Based on Systematic Reviews.

Background: Co-creation is an approach that aims to democratize research and bridge the gap between research and practice, but the potential fragmentation of knowledge about co-creation has hindered progress. A comprehensive database of published literature from multidisciplinary sources can address this fragmentation through the integration of diverse perspectives, identification and dissemination of best practices, and increase clarity about co-creation. However, two considerable challenges exist.

A scoping review of co-creation practice in the development of non-pharmacological interventions for people with Chronic Obstructive Pulmonary Disease: A health CASCADE study.

Background: Incorporating co-creation processes may improve the quality of outcome interventions. However, there is a lack of synthesis of co-creation practices in the development of Non-Pharmacological Interventions (NPIs) for people with Chronic Obstructive Pulmonary Disease (COPD), that could inform future co-creation practice and research for rigorously improving the quality of care.

Objective: This scoping review aimed to examine the co-creation practice used when developing NPIs for people with COPD.

Haemolysin coregulated protein is an exported receptor and chaperone of type VI secretion substrates.

Secretion systems require high-fidelity mechanisms to discriminate substrates among the vast cytoplasmic pool of proteins. Factors mediating substrate recognition by the type VI secretion system (T6SS) of Gram-negative bacteria, a widespread pathway that translocates effector proteins into target bacterial cells, have not been defined. We report that haemolysin coregulated protein (Hcp), a ring-shaped hexamer secreted by all characterized T6SSs, binds specifically to cognate effector molecules.

Diverse type VI secretion phospholipases are functionally plastic antibacterial effectors.

Membranes allow the compartmentalization of biochemical processes and are therefore fundamental to life. The conservation of the cellular membrane, combined with its accessibility to secreted proteins, has made it a common target of factors mediating antagonistic interactions between diverse organisms. Here we report the discovery of a diverse superfamily of bacterial phospholipase enzymes.

Intrarectal immunization and IgA antibody-secreting cell homing to the small intestine.

According to the current paradigm, lymphocyte homing to the small intestine requires the expression of two tissue-specific homing receptors, the integrin α4β7 and the CCL25 receptor CCR9. In this study, we investigated the organ distribution and the homing molecule expression of IgA Ab-secreting cells (ASCs) induced by intrarectal immunization with a particulate Ag, in comparison with other mucosal immunization routes. Intrarectal immunization induces gut-homing IgA ASCs that localize not only in the colon but also in the small intestine, although they are not responsive to CCL25, unlike IgA ASCs induced by oral immunization.

Quantitative single-cell characterization of bacterial interactions reveals type VI secretion is a double-edged sword.

Interbacterial interaction pathways play an important role in defining the structure and complexity of bacterial associations. A quantitative description of such pathways offers promise for understanding the forces that contribute to community composition. We developed time-lapse fluorescence microscopy methods for quantitation of interbacterial interactions and applied these to the characterization of type VI secretion (T6S) in Pseudomonas aeruginosa.

A widespread bacterial type VI secretion effector superfamily identified using a heuristic approach.

Sophisticated mechanisms are employed to facilitate information exchange between interfacing bacteria. A type VI secretion system (T6SS) of Pseudomonas aeruginosa was shown to deliver cell wall-targeting effectors to neighboring cells. However, the generality of bacteriolytic effectors and, moreover, of antibacterial T6S remained unknown.

Use of murine norovirus as a surrogate to evaluate resistance of human norovirus to disinfectants.

Murine norovirus (MNV) was used as a surrogate to study resistance of human norovirus to disinfectants used in hospitals. MNV was sensitive to alcohol, alcohol hand rubs, bleach, and povidone iodine-based disinfectant. Real-time reverse transcription-PCR results indicated that the presence of viral RNA did not correlate with the presence of infectious virus.

Cytohesin binder and regulator (cybr) is not essential for T- and dendritic-cell activation and differentiation.

Cybr (also known as Cytip, CASP, and PSCDBP) is an interleukin-12-induced gene expressed exclusively in hematopoietic cells and tissues that associates with Arf guanine nucleotide exchange factors known as cytohesins. Cybr levels are dynamically regulated during T-cell development in the thymus and upon activation of peripheral T cells. In addition, Cybr is induced in activated dendritic cells and has been reported to regulate dendritic cell (DC)-T-cell adhesion.

Intrarectal immunization with rotavirus 2/6 virus-like particles induces an antirotavirus immune response localized in the intestinal mucosa and protects against rotavirus infection in mice.

Rotavirus (RV) is the main etiological agent of severe gastroenteritis in infants, and vaccination seems the most effective way to control the disease. Recombinant rotavirus-like particles composed of the viral protein 6 (VP6) and VP2 (2/6-VLPs) have been reported to induce protective immunity in mice when administered by the intranasal (i.n.

Granulocyte colony-stimulating factor decreases tumor necrosis factor production in whole blood: role of interleukin-10 and prostaglandin E(2).

Previous reports have indicated that the administration of granulocyte colony-stimulating factor (G-CSF) decreases ex vivo tumor necrosis factor (TNF) production in humans. In this study, we report that daily pretreatment of mice with G-CSF for three days decreases ex vivo lipopolysaccharide (LPS)-induced TNF production in whole blood. Conversely, production of interleukin-10 (IL-10) and prostaglandin E(2) (PGE(2)) is increased.

Jak3-independent trafficking of the common gamma chain receptor subunit: chaperone function of Jaks revisited.

Janus kinases (Jaks) play an essential role in cytokine signaling and have been reported to regulate plasma membrane expression of their cognate receptors. In this study, we examined whether Jak3 and the common gamma chain (gamma(c)) reciprocally regulate their plasma membrane expression. In contrast to interleukin-2Ralpha, gamma(c) localized poorly to the plasma membrane and accumulated in endosomal-lysosomal compartments.

Erythropoietin selectively attenuates cytokine production and inflammation in cerebral ischemia by targeting neuronal apoptosis.

Ischemic brain injury resulting from stroke arises from primary neuronal losses and by inflammatory responses. Previous studies suggest that erythropoietin (EPO) attenuates both processes. Although EPO is clearly antiapoptotic for neurons after experimental stroke, it is unknown whether EPO also directly modulates EPO receptor (EPO-R)-expressing glia, microglia, and other inflammatory cells.

Cytokines and transcription factors that regulate T helper cell differentiation: new players and new insights.

The differentiation of naive CD4+ T cells into subsets of T helper cells is a pivotal process with major implications for host defense and the pathogenesis of immune-mediated diseases. Though the basic paradigm was discovered more than 15 years ago, new discoveries continue to be made that offer fresh insights into the regulation of this process. T helper (TH)1 cells produce interferon (IFN)-gamma, promoting cell-mediated immunity and control of intracellular pathogens.

Erythropoietin exerts an anti-inflammatory effect on the CNS in a model of experimental autoimmune encephalomyelitis.

In recent work we reported that systemically administered erythropoietin (EPO) crosses the blood-brain barrier and has protective effects in animal models of cerebral ischemia, brain trauma and in a rat model of experimental autoimmune encephalomyelitis (EAE). Here we characterize the effect of systemic EPO on the inflammatory component of actively induced, acute EAE in Lewis rats. Administration of EPO at doses of 500-5000 U/kg bw i.

HMGB-1, a DNA-binding protein with cytokine activity, induces brain TNF and IL-6 production, and mediates anorexia and taste aversion.

High-mobility group protein-1 (HMG-1 also termed HMGB-1), a DNA-binding protein, regulates gene transcription and stabilizes nucleosome formation. HMG-1 was recently implicated as a cytokine, because it is a late-acting mediator of endotoxin lethality that induces the release of pro-inflammatory cytokines from monocytes. Here it is shown that administration of HMG-1 into the cerebral ventricles decreases food intake (food intake=4.

Preventive administration of Mycobacterium tuberculosis 10-kDa heat shock protein (hsp10) suppresses adjuvant arthritis in Lewis rats.

Adjuvant arthritis (AA) can be induced in Lewis rats by immunization with Mycobacterium tuberculosis (Mt) in oil. We have investigated the modulation of AA by mycobacterial 10-kDa heat shock protein (hsp10), administered according to several protocols known to induce immune tolerance and immune deviation. Subcutaneous immunization with hsp10 in aqueous solution did not induce a cellular immune response, evaluated as delayed-type hypersensitivity (DTH) reaction, although anti-hsp10 antibodies, mainly of the IgG2a isotype, were detected in serum of treated animals.

Cybr, a cytokine-inducible protein that binds cytohesin-1 and regulates its activity.

Cytokines regulate lymphocyte development and differentiation, but precisely how they control these processes is still poorly understood. By using microarray technology to detect cytokine-induced genes, we identified a cDNA encoding Cybr, which was increased markedly in cells incubated with IL-2 and IL-12. The mRNA was most abundant in hematopoietic cells and tissues.

Decrease in brain cytochrome P450 enzyme activities during infection and inflammation of the central nervous system.

The effect of infection and inflammation of the central nervous system (CNS) on cytochrome-P450-dependent activities in brain, spinal cord and liver microsomes was determined. For this, two models were used: (1) the intracerebroventricularly injected lipopolysaccharide (LPS) model and (2) the experimental auto-immune encephalomyelitis (EAE) model. In the LPS model, aminopyrine N-demethylase (AMND) and ethoxycoumarin O-deethylase (ECOD) activities (both P450 dependent) were significantly decreased (35 and 20%, respectively) in brain microsomes.

Increased peripheral benzodiazepine binding sites and pentraxin 3 expression in the spinal cord during EAE: relation to inflammatory cytokines and modulation by dexamethasone and rolipram.

We have studied the mRNA expression of pentraxin 3 (PTX3) and the binding of the peripheral-type benzodiazepine receptor (PBR) ligand, [3H]-PK11195, in the spinal cord of Lewis rats where EAE was actively induced. PTX3 was induced during the active phase of EAE (day 10-14), it remained high up to 30 days and disappeared only 60 days later. Similarly, PK11195 binding peaked at day 14-17 during the recovery and it disappeared by day 60.
