Abstract Background Despite the significant burden of alcohol use disorders (AUD), there is a large treatment gap, especially in settings and populations affected by armed conflict. A key barrier to care is the lack of contextually relevant interventions and adequately skilled human resources to deliver them. This paper describes the systematic development of the CHANGE intervention, a potentially scalable psychological intervention for people with co-existing AUD and psychological distress in conflict-affected populations, delivered by non-specialist workers (NSWs). Methods CHANGE was developed in sequential steps: (1) identifying potential treatment strategies through a meta-review and Delphi survey with international experts; (2) in-depth interviews (IDIs) with key stakeholders from the study settings in Uganda and Ukraine; and (3) three consultative workshops with international experts and experts from Uganda and Ukraine to develop a theoretical framework for the intervention informed by outputs of the Delphi and IDIs. Results In the Delphi survey, experts reached agreement on the acceptability, feasibility and potential effectiveness of the following components: identify high-risk situations, problem solving skills, assessment, handling drinking urges, communication skills, pros and cons of drinking, and identifying high-risk situations. From the IDIs we identified (a) causal attributions for using alcohol e.g., psychosocial stressors; (b) cultural norms related to alcohol consumption such as patriarchal stereotypes; and (c) coping strategies to deal with drinking problems such as distraction. The CHANGE intervention developed through the consultative workshops can be delivered in three sequential phases focussed on assessment, feedback, and information (Phase 1); providing the client with need-based skills for dealing with high-risk situations related to alcohol use (Phase 2), and relapse prevention and management (Phase 3). Conclusions CHANGE is a contextually relevant and potentially scalable treatment for co-existing AUD and psychological distress to be delivered by NSWs to conflict-affected populations. Effectiveness and cost-effectiveness of CHANGE will be tested in Uganda and Ukraine.

Background: Alcohol misuse is a significant health problem among forcibly displaced populations including male South Sudanese refugees in northern Uganda, yet interventions are sorely lacking. Developing an explanatory model of alcohol misuse in this population is the first step to designing appropriate and effective interventions. The aim of the current study was to examine alcohol misuse in this setting and to conceptualize an explanatory model of alcohol misuse. Method: A total of 57 interviews were conducted with male refugees (18+ years) with alcohol misuse (n = 17), their family members (n = 15), community and religious leaders (n = 15), and mental health and psychosocial support providers (n = 10) in Rhino Camp settlement in northern Uganda. A thematic analysis approach was used to inductively analyze the data. Results: Alcohol misuse was identified as a significant psychosocial problem among men in this setting. The adversity (e.g. trauma, loss, poverty), psychological distress (e.g. demoralization), perpetuators (e.g. ease of availability of alcohol, family conflict), and consequences of alcohol use (e.g. interpartner violence, exacerbated poverty) were identified. An explanatory model emerged from the data showing a reinforcing relationship in which adversity causes psychological distress, which leads to increased alcohol use via a number of personal, interpersonal, community and societal perpetuators, and over time increased alcohol use amplifies psychological distress which further increases alcohol misuse. Conclusions: Given the need to address alcohol misuse in this population, this explanatory model of alcohol misuse can be used to inform prevention and treatment interventions for alcohol misuse. These interventions should endeavor to address the identified determinants of alcohol misuse while being cognizant of the social and cultural considerations specific to males in this population.

In the proposed paper, an artificial neural network (ANN) algorithm is applied to predict the electronic circuit outputs of voltage signals in Industry 4.0/5.0 scenarios. This approach is suitable to predict possible uncorrected behavior of control circuits affected by unknown noises, and to reproduce a testbed method simulating the noise effect influencing the amplification of an input sinusoidal voltage signal, which is a basic and fundamental signal for controlled manufacturing systems. The performed simulations take into account different noise signals changing their time-domain trend and frequency behavior to prove the possibility of predicting voltage outputs when complex signals are considered at the control circuit input, including additive disturbs and noises. The results highlight that it is possible to construct a good ANN training model by processing only the registered voltage output signals without considering the noise profile (which is typically unknown). The proposed model behaves as an electronic black box for Industry 5.0 manufacturing processes automating circuit and machine tuning procedures. By analyzing state-of-the-art ANNs, the study offers an innovative ANN-based versatile solution that is able to process various noise profiles without requiring prior knowledge of the noise characteristics.

Background: Although interest in studies evaluating the outcomes of rotator cuff repair is steadily increasing, the results and tendon integrity after arthroscopic rotator cuff repair in elderly patients have only been minimally investigated. The aim of this study was to evaluate clinical outcomes and repair integrity in patients over 65 years of age who underwent arthroscopic repair of full-thickness rotator cuff tears. Methods: A retrospective study was conducted with the following inclusion criteria: (1) elective shoulder arthroscopy for rotator cuff repair for full-thickness posterosuperior tears; (2) age over 65 years at surgery; and (3) participation in 24 months of follow-up. Preoperatively, the range of motion (ROM) and the Constant-Murley Score (CMS) and at follow-up, the ROM, the 12-Item Short Form Survey, the American Shoulder and Elbow Surgeons, and the CMS were evaluated; an ultrasonographic assessment of tendon integrity was performed according to the adapted Sugaya classification. Results: The final sample consisted of 110 patients with an average age of 69.2 ± 3.5 years. The mean duration of nonoperative management before surgery was 2.6 ± 0.8 months. The mean period of preoperative physical therapy was 0.6 ± 0.9 months. ROM and CMS showed statistically significant improvement (all P

Abstract The evidence on the impacts of climate change on mental health and wellbeing is growing rapidly. The objective of this scoping review is to understand the extent and type of existing mental health and psychosocial interventions aimed at addressing the mental health and psychosocial impacts of climate change. A scoping review methodology was followed. MEDLINE, PsycINFO, and Web of Science databases were searched from inception to May 2022. Comprehensive gray literature search, including expert consultation, was conducted to identify interventions for which peer-reviewed academic literature may not yet be available. Data on intervention type, setting, climate stressor, mental health outcome, evaluation, and any other available details were extracted, and results were summarized narratively. Academic literature search identified 16 records and gray literature search identified a further 24 records. Altogether, 37 unique interventions or packages of interventions were identified. The interventions act at the levels of microsystem, mesosystem, exosystem, and macrosystem through diverse mechanisms. While most interventions have not been formally evaluated, promising preliminary results support interventions in low- and middle-income-country settings disproportionately affected by climate disasters. Interventions from multidisciplinary fields are emerging to reduce psychological distress and enhance mental health and wellbeing in the context of climate change. This scoping review details existing evidence on the interventions and summarizes intervention gaps and lessons learned to inform continued intervention development and scale-up interventions.

This paper discusses a methodology to improve the prevention processes of chronic diseases such as diabetes and strokes. The research motivation is to find a new methodological approach to design advanced Diagnostic and Therapeutic Care Pathways (PDTAs) based on the prediction of chronic disease using telemedicine technologies and machine learning (ML) data processing techniques. The aim is to decrease health risk and avoid hospitalizations through prevention. The proposed method defines a Process Mining Organization (PMO) model, managing risks using a PDTA structured to prevent chronic risk. Specifically, the data analysis is focused on stroke risk. First, we applied and compared the Random Forest (RF) and Gradient Boosted Trees (GBT) supervised algorithms to predict stroke risk, and then, the Fuzzy c-Means unsupervised algorithm to cluster information on the predicted results. The application of the proposed approach is able to increase the efficiency of healthcare human resources and drastically decrease care costs.

Process mining organizatioQn (PMO) is an innovative approach based on artificial intelligence (AI) decision making suitable for designing healthcare processes for human resource (HR) organizations. The proposed work suggests some examples of PMO-based Business Process Modeling and Notation (BPMN) workflows by highlighting the advances in HR management and in risk decrease according to healthcare scenarios. Specifically proposed are different examples of “TO BE” process pipelines related to an upgrade of the organizational healthcare framework, including digital technologies and telemedicine. Important elements are provided to formulate HR management guidelines supporting PMO design. The proposed BPMN workflows are the result of different consulting actions in healthcare institutions based on the preliminary mapping of “AS IS” processes highlighting bottlenecks and needs in HR organization. A pilot experimental dataset is used to show how it is possible to apply AI algorithms providing organization corrective actions. The paper is mainly focused on discussing some validated BPMN models managing HR in the healthcare sector. The methodology is based on the application of the BPMN approach to deploy human resource organizational processes. The results show AI data-driven workflows adopted in healthcare and examples of AI fuzzy c-means outputs addressing organizational actions.

La rilevazione dei cambiamenti ambientali da dati telerilevati è ampiamente usata in molti contesti applicativi, sia per effettuare un controllo periodico e sistematico del territorio (variazione dell'estensione abitativa, monitoraggio delle zone vegetate, etc.) sia per la gestione ed il controllo di situazioni di emergenza dovute al verificarsi di disastri naturali, quali frane, alluvioni, incendi [1]. Per catturare qualsiasi cambiamento ambientale, è indispensabile considerare immagini multi-temporali della stessa area geografica [2]. L'obiettivo dell'attività 3.2 è stato quello di progettare e realizzare una metodologia, matematicamente e statisticamente ben fondata, in grado di fondere immagini multi-temporali relative alla stessa area geografica con l'obiettivo di rilevare in modo automatico i cambiamenti a terra.

Malignant melanoma (MM) is the “great mime” of dermatopathology, and it can present such rare variants that even the most experienced pathologist might miss or misdiagnose them. Naevoid melanoma (NM), which accounts for about 1% of all MM cases, is a constant challenge, and when it is not diagnosed in a timely manner, it can even lead to death. In recent years, artificial intelligence has revolutionised much of what has been achieved in the biomedical field, and what once seemed distant is now almost incorporated into the diagnostic therapeutic flow chart. In this paper, we present the results of a machine learning approach that applies a fast random forest (FRF) algorithm to a cohort of naevoid melanomas in an attempt to understand if and how this approach could be incorporated into the business process modelling and notation (BPMN) approach. The FRF algorithm provides an innovative approach to formulating a clinical protocol oriented toward reducing the risk of NM misdiagnosis. The work provides the methodology to integrate FRF into a mapped clinical process.

The paper proposes an innovative model able to predict the output signals of resistance and capacitance (RC) low-pass filters for machine-controlled systems. Specifically, the work is focused on the analysis of the parametric responses in the time- and frequency-domain of the filter output signals, by considering a white generic noise superimposed onto an input sinusoidal signal. The goal is to predict the filter output using a black-box model to support the denoising process by means of a double-stage RC filter. Artificial neural networks (ANNs) and random forest (RF) algorithms are compared to predict the output of noisy signals. The work is concluded by defining guidelines to correct the voltage output by knowing the predictions and by adding further RC elements correcting the distorted signals. The model is suitable for the implementation of Industry 5.0 Digital Twin (DT) networks applied to manufacturing processes.

In conflict-affected settings, prevalence of alcohol use disorders (AUDs) can be high. However, limited practical information exists on AUD management in low-income settings. Using a theory of change (ToC) approach, we aimed to identify pathways influencing the implementation and maintenance of a new transdiagnostic psychological intervention (“CHANGE”), targeting both psychological distress and AUDs in humanitarian settings. Three half-day workshops in Uganda engaged 41 stakeholders to develop a ToC map. ToC is a participatory program theory approach aiming to create a visual representation of how and why an intervention leads to specific outcomes. Additionally, five semi-structured interviews were conducted to explore experiences of stakeholders that participated in the ToC workshops. Two necessary pathways influencing the implementation and maintenance of CHANGE were identified: policy impact, and mental health service delivery. Barriers identified included policy gaps, limited recognition of social determinants and the need for integrated follow-up care. Interviewed participants valued ToC’s participatory approach and expressed concerns about its adaptability in continuously changing contexts (e.g., humanitarian settings). Our study underscores ToC’s value in delineating context-specific outcomes and identifies areas requiring further attention. It emphasizes the importance of early planning and stakeholder engagement for sustainable implementation of psychological interventions in humanitarian settings.

Our aim was to examine mental health needs and access to mental healthcare services among Syrian refugees in the city of Leipzig, Germany. We conducted a cross-sectional survey with Syrian refugee adults in Leipzig, Germany in 2021/2022. Outcomes included PTSD (PCL-5), depression (PHQ-9), anxiety (GAD-7) and somatic symptom (SSS-8). Descriptive, regression and effect modification analyses assessed associations between selected predictor variables and mental health service access. The sampling strategy means findings are applicable only to Syrian refugees in Leipzig. Of the 513 respondents, 18.3% had moderate/severe anxiety symptoms, 28.7% had moderate/severe depression symptoms, and 25.3% had PTSD symptoms. A total of 52.8% reported past year mental health problems, and 48.9% of those participants sought care for these problems. The most common reasons for not accessing mental healthcare services were wanting to handle the problem themselves and uncertainty about where to access services. Adjusted Poisson regression models (n = 259) found significant associations between current mental health symptoms and mental healthcare service access (RR: 1.47, 95% CI: 1.02–2.15, p = 0.041) but significance levels were not reached between somatization and trust in physicians with mental healthcare service access. Syrian refugees in Leipzig likely experience high unmet mental health needs. Community-based interventions for refugee mental health and de-stigmatization activities are needed to address these unmet needs in Leipzig.

COVID-19 is having substantial impacts on research conduct, including clinical trials. However, there is limited research investigating the impact of the pandemic on the conduct of clinical trials and barriers to the delivery of interventions. The current study contributes to filling this gap by investigating the impacts of COVID-19 and related mitigation strategies in the context of five randomised controlled trials (RCTs) of lay-delivered psychological interventions for Syrian refugees in Jordan, Lebanon, the Netherlands, Switzerland, and Turkey. We conducted semi-structured interviews with purposively selected researchers (N = 14) across all five countries. Data were analysed using codebook thematic analysis. The trial researchers highlighted how COVID-19 has had pervasive impacts across different components of the trial including recruitment, assessment, intervention delivery, and supervision. These impacts were considered to influence the external and internal scientific validity of these trials, as well as some aspects of trial administration such as budgeting and the workforce. Various mitigation strategies to adapt to constraints imposed by pandemic responses were described by researchers, such as shifting to a remote intervention delivery and evaluation or adding COVID-19 measures to better understand the impacts of COVID-19 on outcome data. The current piece provides an account of the impacts of COVID-19 on the conduct of trials of lay-delivered psychological interventions for refugees in five countries. Our findings will be valuable for researchers testing similar interventions during COVID-19 and other public health emergencies.

The proposed paper introduces an innovative approach based on the implementation of a multi-level Decision Support System (DSS) modelling processes in the industry. Specifically, the work discusses a theoretical Process Mining (PM) DSS model gaining digital knowledge by means of logics that are able to select the best decisions. The PM model is applied to an open dataset simulating a working scenario and defining a possible safety control method based on the risk assessment. The application of the PM model provides automatic alerting conditions based on a threshold of values detected by sensors. Specifically, the PM model is applied to worker security systems characterized by the environment with a risk of emission of smoke and gases. The PM model is improved by Artificial Intelligence (AI) algorithms by strengthening information through prediction results and improving the risk analysis. An Artificial Neural Network (ANN) MultilaLayer Perceptron (MLP) algorithm is adopted for the risk prediction by achieving the good computational performance of Mean Absolute Error (MAE) of 0.001. The PM model is first sketched by the Business Process Modelling and Notation (BPMN) method, and successively executed by means of the Konstanz Information Miner (KNIME) open source tool, implementing the process-controlling risks for different working locations. The goal of the paper is to apply the theoretical PM model by means of open source tools by enhancing how the multi-level approach is useful for defining a security procedure to control indoor worker environments. Furthermore, the article describes the key variables able to control production and worker safety for different industry sectors. The presented DSS PM model also can be applied to industry processes focused on production quality.

The brain health and development implications of climate change are situated within a large and rapidly increasing body of evidence that addresses the physical and mental health impacts and implications of extreme and worsening environments. The costs to individuals and societies of negatively impacted brain development are profound – be it in the form of diagnosable developmental disability, reduced cognitive capacity, or areas of behavioral functioning. We have sought to describe the key risk domains that climate change presents with respect to healthy brain development, from the prenatal through to youth stages. Scoping review methods and an a priori search strategy were used to address the question: What are the major considerations of the peer-reviewed literature that address climate change as it relates to brain development and health from early development through to youth populations? Themes from the identified papers were charted, and findings were summarized through a consensus process. A total of 40 papers were identified in the search, spanning 2008–2022. Based on the thematic analysis, results are organized into the following nine themes: 1) heat extremes, 2) weather extremes and stress, 3) air pollution, 4) vector and waterborne illnesses, 5) malnutrition, 6) equity, 7) economic implications, 8) methods issues, and 9) responses. There is a clear consensus amongst the papers in this review suggesting that changing climate patterns and weather extremes have substantial and wide-ranging effects on developing brains. A range of responses are proposed with an emphasis upon early intervention and better data.

Introduction: Climate change is causing far-reaching yet underappreciated worsening of outcomes across the mental health and wellbeing spectrum. Despite increasing attention to the mental health impacts of climate change, an absence of a clear, cross-sectoral agenda for action has held back progress against the dual and interconnected challenges of supporting human and planetary health. This study aims to serve as an essential first step to address this gap. Methods: Harnessing the expertise of a diverse panel of 61 participants, representing 24 nationalities, this study developed and prioritized recommendations for action on climate change and mental health across the relevant sectors of research, policy, healthcare and the third sector, and used a Delphi-style methodology to examine their feasibility and importance. Results: Broadly, the prioritized recommendations highlighted the need to expand the evidence base, work collaboratively across sectors, and raise awareness. While broadly there was consensus on recommendation importance, there was greater variation in the reported feasibility of the recommendations, which differed across settings. Other common themes included the need for cultural and resource contextualization, raising awareness of and addressing mental health co-benefits via climate action, and working with communities with lived experience to develop and implement the findings. As there may be some interdependencies between the recommendations, further work needs to identify how best to implement them. Conclusion: The recommendations serve as a robust and evidence-based framework that can be used as a foundation to devise locally appropriate, concrete implementation strategies matching levels of need and resource. These also serve as a clear call to action for investment from leaders across sectors to ensure they are realized.

Here we characterize, in Chinese hamster ovary-k1 cells, the intracellular pathway that from somatostatin receptor 1 (SSTR1), leads to the activation of PTPeta and that involves, in a multimeric complex and sequential activation, the tyrosine kinases Janus kinase (JAK) 2 and Src, and the cytosolic phosphotyrosine phosphatase SHP-2. We show that inhibitors of JAK2 and Src and dominant-negative mutants of SHP-2 and Src abolished the SSTR1-mediated PTPeta activation, suggesting that all these effectors participate in the activation of PTPeta. In basal conditions, JAK2 forms a multimeric complex with SHP-2, Src and PTPeta. In response to SST, JAK2 is activated in a G protein-dependent manner, dissociates from and phosphorylates SHP-2, increasing its activity. Subsequently, SHP-2 dissociates from Src, dephosphorylates the Src inhibitory tyrosine-529, and causes an autocatalytical increase of the phosphorylation of Src tyrosine 418, located inside its kinase activation loop. Active Src, in turn, controls the activity of PTPeta, via a direct interaction and phosphorylation of the phosphatase. These data for the first time depict an intracellular pathway involving a precise sequence of interactions and cross-activation among tyrosine phosphatases and kinases acting upstream of PTPeta. In particular the sequential activation of JAK2, SHP-2, and Src conveys the molecular signaling from SSTR1 to the activation of this phosphatase that is responsible for the final biological effects of SST.

Summary OBJECTIVE Somatostatin is an endogenous inhibitor of hormone secretion and cell proliferation. Treatment with somatostatin analogues in humans causes a reduction in size and secretory activity of endocrine tumours, including GH-secreting pituitary adenomas. This study was aimed to characterize the intracellular mechanisms mediating the in vitro antiproliferative and antisecretory effects of somatostatin and its analogue lanreotide, on primary cultures of GH-secreting pituitary adenoma cells. DESIGN Thirteen GH-secreting pituitary adenoma postsurgical specimens were analysed for somatostatin receptor (SSTR) mRNA expression and a subset of them was analysed in vitro for the effect of somatostatin on cell proliferation, assessed by means of [ 3 H]-thymidine uptake, and GH release, using an immunoradiometric assay. Moreover, the intracellular signalling involved in such effects has been studied. RESULTS All the adenomas analysed expressed at least one somatostatin receptor subtype mRNA. SSTR2 mRNA was identified in 77% of the adenomas, SSTR1 and SSTR3 in 69% and SSTR5 in 60%. Somatostatin and lanreotide inhibited cell proliferation in phorbol ester (PMA)-stimulated conditions (10/13 adenomas), as well as after fetal calf serum (3/3 adenomas) or IGF-I stimulation (2/2 adenomas). Conversely, GHRH or forskolin treatments did not significantly affect DNA synthesis in adenoma cells in the presence or absence of somatostatin (2/2 and 4/4 adenomas, respectively). Vanadate pretreatment reversed somatostatin inhibition of PMA-induced DNA synthesis suggesting an involvement of tyrosine phosphatase in this effect (2/2 adenomas); this was confirmed by the direct induction of tyrosine phosphatase activity in two adenomas after somatostatin treatment. Somatostatin and also lanreotide caused significant inhibition of phorbol ester, forskolin, GHRH and KCl-dependent increase of GH secretion in the culture medium. Moreover, voltagesensitive calcium channel activity induced by 40 m M KCl depolarization in microfluorimetric analysis, was significantly reduced (5/5 adenomas). CONCLUSIONS These data show that somatostatin and lanreotide inhibit human GH-secreting pituitary adenoma cell proliferation and hormone release in vitro , and suggest that the activation of tyrosine phosphatases may represent intracellular signals mediating the antiproliferative effects and that the inhibition of the voltage-dependent calcium channels and adenylyl cyclase activities may control GH secretion.

Abstract Background Adolescents in low-resource urban settings in Brazil are often exposed to high levels of trauma that can result in post-traumatic stress disorder (PTSD). However, preliminary evidence indicates that PTSD tends to be under-reported in Brazilian health services, despite the high prevalence of trauma. Additionally, little is known about the perceived applicability among clinicians of the new ICD-11 diagnosis of complex PTSD (CPTSD), despite its potential relevance for contexts of chronic trauma. The current study investigated local understandings of PTSD and CPTSD among health professionals working with adolescents in violent neighbourhoods of São Paulo city. Methods Semi-structured interviews were conducted with 58 health professionals working at both the primary care and specialized mental health levels in two areas of São Paulo city with high levels of community violence. Results Most participants knew about PTSD, but most did not know about CPTSD. There were mixed views concerning the commonality of PTSD among adolescents exposed to community violence. Many participants reported having no experience working with patients with the PTSD diagnosis. According to some, community violence was normalized by adolescents and health professionals, and did not result in PTSD. Others highlighted how they did not use psychiatric diagnoses in their practice, had critical perspectives towards psychiatric diagnoses and/or PTSD, or simply knew little about PTSD. Furthermore, many highlighted how the chronic nature of multiple traumas experienced by adolescents often resulted in complex clinical presentations characterised by many symptoms beyond PTSD. The diagnosis of CPTSD was considered appropriate to the context by many participants as it captured the complex traumatic histories and symptom presentations of adolescents exposed to community violence in Brazil. Conclusions These findings have important implications for the assessment and treatment of mental health among adolescents exposed to community violence in Brazil.

This study analyzes the determinants of the "Broadband Price Index" in Europe. The data used refers to 28 European countries between 2016 and 2021. The database used is the Digital, Economy, and Society Index-DESI of the European Commission. The data were analyzed using the following econometric techniques, namely Panel Data with Random Effects, Panel Data with Fixed Effects, Pooled OLS, WLS and Dynamic Panel. The value of the "Broadband Price Index" is positively associated with the DESI Index and "Connectivity", while it is negatively associated with "Fixed Broadband Take Up", "Fixed Broadband Coverage", "Mobile Broadband", "e-Government", "Advanced Skills and Development", "Integration of Digital Technology", "At Least Basic Digital Skills", "Above Basic Digital Skills", and "At Least Basic Software Skills". A cluster analysis was carried out below using the k-Means algorithm optimized with the Silhouette coefficient. The analysis revealed the existence of three clusters. Finally, an analysis of the machine learning algorithms was carried out to predict the future value of the "Broadband Price Index". The result shows that the most useful algorithm for prediction is the Artificial Neural Network-ANN, with an estimated value equal to an amount of 9.21%.

The climate crisis is adversely impacting mental health and wellbeing. Research on interventions to address these impacts remains scarce, particularly in humanitarian settings. This study used a modified Delphi process to identify research priorities for mental health and psychosocial support (MHPSS) and climate crisis research, drawing on the perspectives of those with demonstrated interest, engagement, and/or expertise in MHPSS and the climate crisis. The study consisted of two online surveys. In the first survey, demographic and qualitative data were collected and analysed to generate a list of research priorities and a concept map to describe the area of climate crisis and MHPSS research. In the second survey, participants ranked and rated their agreement with priorities and provided recommendations for modification of individual priorities and the concept map. In total, 91 experts working primarily but not exclusively in MHPSS programming or practice participated in the study. Consensus was reached on 20 research priorities, and 8 top-ranked priorities were identified. Given the urgency of the climate crisis, MHPSS and climate crisis research must contribute to mitigating and adapting to the climate crisis while promoting both mental health and psychosocial wellbeing and just international development.

Climate change is negatively impacting mental health through multiple pathways. Research to date has largely focused on characterising the link between climate change and mental health and no mental health and psychosocial support intervention has been explicitly designed to address the mental health consequences of climate change. In this commentary, we argue that brief, scalable psychological interventions represent an opportunity to fill this gap. Brief psychological interventions have been shown to be effective in the context of disasters, armed conflict and displacement, which have all been predicted to increase because of climate change. Brief psychological interventions are also likely to be relevant in the context of chronic climate stressors including temperature and sea-level rise or droughts. Additionally, they hold the potential to be used within a prevention and promotion framework, which is likely to be relevant in the context of increasing cumulative and overlapping climate-related adversities. Finally, brief psychological interventions could address several implementation challenges resulting from global climate change and could also be integrated with other programmes, including those that support climate change adaptation and mitigation. Research is urgently needed to provide evidence for the implementation and effectiveness of brief psychological interventions in the context of climate change.

We here investigated the anti-inflammatory activity of a polymethoxylated flavone-containing fraction (PMFF) from Citrus sinensis and of a prenylflavonoid-containing one (PFF) from Humulus lupulus, either alone or in combination (MIX). To this end, an in vitro model of inflammatory bowel disease (IBD), consisting of differentiated, interleukin (IL)-1β-stimulated Caco-2 cells, was employed. We demonstrated that non-cytotoxic concentrations of either PMFF or PFF or MIX reduced nitric oxide (NO) production while PFF and MIX, but not PMFF, also inhibited prostaglandin E2 release. Coherently, MIX suppressed both inducible NO synthase and cyclooxygenase-2 over-expression besides NF-κB activation. Moreover, MIX increased nuclear factor erythroid 2–related factor 2 (Nrf2) activation, heme oxygenase-1 expression, restoring GSH and reactive oxygen and nitrogen species (RONs) levels. Remarkably, these effects with MIX were stronger than those produced by PMFF or PFF alone. Noteworthy, nobiletin (NOB) and xanthohumol (XTM), two of the most represented phytochemicals in PMFF and PFF, respectively, synergistically inhibited RONs production. Overall, our results demonstrate that MIX enhances the anti-inflammatory and anti-oxidative effects of the individual fractions in a model of IBD, via a mechanism involving modulation of NF-κB and Nrf2 signalling. Synergistic interactions between NOB and XTM emerge as a relevant aspect underlying this evidence.

Stromal cell-derived factor-1 (SDF-1) is a chemokine of the CXC subfamily that exerts its effects via CXCR4, a G-protein-coupled receptor. CXCR4 is often expressed by tumor cells, and its activation causes tumor cell proliferation. Using GH4C1 cells, here we show that SDF-1 induced cell proliferation in a dose-dependent manner. Thus, we evaluated the intracellular signaling involved in this effect. SDF-1 increased cytosolic [Ca2+] and activated Pyk2, ERK1/2, and BKCa channels. To correlate these intracellular effectors with the proliferative activity of SDF-1, we inhibited their activity using BAPTA-AM (Ca2+ chelator), PD98059 (MEK inhibitor), salicylate (Pyk2 inhibitor), and TEA (K+ channel blocker). All these compounds reverted SDF-1-induced proliferation, suggesting the involvement of multiple intracellular pathways. To identify a possible crosstalk and a molecular ordering among these pathways, we tested these antagonists on SDF-1-dependent activation of ERK1/2, Pyk2, and BKCa channels. We report that the inhibition of [Ca2+]i increase or the blockade of BKCa channel activity did not affect ERK1/2 activation by SDF-1; Pyk2 activation was purely Ca2+-dependent, not involving ERK1/2 or BKCa channels; and BKCa channel activity was antagonized by Pyk2 but not by ERK1/2 inhibitors. These data suggest that SDF-1-dependent increase of [Ca2+]i activates Pyk2, which, in turn, regulates BKCa channel activity. Conversely, ERK1/2 activation is an independent phenomenon. In conclusion, we demonstrate that SDF-1 induces proliferation of GH4C1 cells, suggesting that the activation of CXCR4 may represent a novel regulatory mechanism for pituitary cell proliferation which may contribute to pituitary adenoma development.

Recent evidence indicates that cancer cells express chemokine (CK) receptors and that their signaling is crucial for tumor proliferation, migration, and angiogenesis. The profiles of expression of CXC CK receptors (CXCR1-5) and their main ligands (growth-related oncogene, GRO1-2-3/CXCL1-2-3; interleukin 8, IL-8/CXCL8; monokine-induced gamma-interferon MIG/CXCL9; gamma-interferon-inducible-protein-10, IP-10/CXCL10; stromal cell-derived factor-1, SDF1/CXCL12; B-cell activating CK-1, BCA-1/CXCL13) were analyzed by reverse transcription polymerase chain reaction (RT-PCR) in surgical samples of human meningiomas. All the five receptors displayed high percentages of positive cases: 92% CXCR1, 89% CXCR2, 83% CXCR3, 78% CXCR4, and 94% CXCR5. Conversely, their ligands showed a lower pattern of expression: 40% IL-8, 42% GRO1-3, 42% IP-10, 28% MIG, 53% SDF1, and 3% BCA-1. SDF1/CXCR4 interaction plays a pivotal role in cancer proliferation. Thus, the signaling mechanisms activated by the exclusive binding between SDF1 and CXCR4 was investigated in 12 primary cultures from meningioma tissues. CXCR4 was functionally coupled as demonstrated by the significant increase of DNA synthesis in meningioma cells in response to SDF1, measured by [3H]-thymidine uptake. In three primary cultures, the SDF1-dependent mitogenic activity was associated with a marked phosphorylation of extracellular signal-regulated kinase (ERK1/2) as evaluated by Western blots. PD98059 (a MEK inhibitor) significantly reduced ERK1/2 activation, thus linking the SDF1/CXCR4 pathway to meningioma cell proliferation via ERK1/2 signal transduction. We demonstrate, for the first time in human meningiomas, the simultaneous expression of CXCR1-5 and their CKs and the mitogenic activity of SDF1/CXCR4, suggesting a pivotal role of these receptor-ligand pairs in meningeal tumors.

Background Climate change is having significant impacts on health and mental health across Europe and globally. Such effects are likely to be more severe in climate change hotspots such as the Mediterranean region, including Italy. Objective To review existing literature on the relationship between climate change and mental health in Italy, with a particular focus on trauma and PTSD. Methods A scoping review methodology was used. We followed guidance for scoping reviews and the PRISMA Extension for Scoping Reviews (PRISMA-ScR) checklist. We searched for literature in MEDLINE, Global Health, Embase and PsycINFO. Following screening, data was extracted from individual papers and a quality assessment was conducted. Given the heterogeneity of studies, findings were summarized narratively. Results We identified 21 original research articles investigating the relationship between climate change and mental health in Italy. Climate change stressors (heat and heatwaves in particular) were found to have several negative effects on various mental health outcomes, such as a higher risk of mortality among people with mental health conditions, suicide and suicidal behaviour and psychiatric morbidity (e.g. psychiatric hospitalization and symptoms of mental health conditions). However, there is little research on the relationship between climate change and trauma or PTSD in the Italian context. Conclusions More attention and resources should be directed towards understanding the mental health implications of climate change to prevent, promote, and respond to the mental health needs of Italy and the wider Mediterranean region. HIGHLIGHTS • Climate change stressors in Italy were found to have detrimental impacts on various mental health outcomes, such as psychiatric mortality and morbidity. • Little research on the relationship between climate change stressors and PTSD exists in Italy.

Background: Disasters can have long-lasting impacts on mental health. Intrusive memories have been found to be common and persistent in the aftermath of earthquakes. Objective: To explore, using diaries, intrusive memories’ presence, content, characteristics, and relationship with probable post-traumatic stress disorder (PTSD) in a small rural community exposed to mass destruction and loss of life. Methods: Survivors of the 2016–2017 Central Italy earthquakes (N = 104) were first interviewed to investigate the presence of intrusive memories of the disaster. Those that reported intrusive memories were subsequently asked to complete a 7-day paper-and-pen diary tracking their spontaneous memories of the earthquake events. Results: Twenty months after the earthquakes, 49% (n = 51) of the sample reported having experienced intrusive memories post-earthquake and 38% (n = 39) reported at least one intrusive memory in their diaries. Memories were rated as being distressing, vivid, and experienced as a mixture of images and thoughts. The content of intrusive memories generally focused on sensations and experiences during the earthquake. Other common categories of content were the material environment and physical objects as well as human loss & death. Several memories had a social focus. A minority of memories contained more positive content as well as content from before and after the earthquake. Some participants (28%) experienced repeated intrusive memories of the same content. Memories of participants with and without probable PTSD did not significantly differ on characteristics or content. Conclusions: Intrusive memories can be common, distressing, and persistent occurrences following disasters, even in survivors not suffering from probable PTSD. Highlights Intrusive memories were common, distressing, and vivid more than 1-year post-disaster. They captured peri-earthquake sensations, material destruction, death, and social interactions. No difference in content or characteristics was found between participants with and without probable PTSD.

Here we characterize the intracellular effectors of the antiproliferative activity of somatostatin in glioma cell lines and post-surgical specimens. The responsiveness to somatostatin correlated with the expression of the phosphotyrosine phosphatase DEP-1/PTPeta, identified in C6 and U87MG cells, in which somatostatin inhibited cell growth. The expression of a dominant negative mutant of DEP-1/PTPeta in C6 cells abolished somatostatin effects, confirming the involvement of this phosphotyrosine phosphatase in such effects. Somatostatin treatment increased the activity of DEP-1/PTPeta and inhibited ERK1/2 activation. Conversely, basic fibroblast growth factor-dependent MEK phosphorylation was not affected, suggesting a direct effect on ERK1/2. In vitro experiments showed that PTPeta was able to interact and dephosphorylate ERK1/2 activated by basic fibroblast growth factor. Furthermore, by transfecting PTPeta in the somatostatin-unresponsive, DEP-1/PTPeta-deficient U373MG cells, the somatostatin-dependent control of cell proliferation was recovered. Finally we evaluated the requirement for DEP-1/PTPeta in somatostatin inhibition of cell proliferation in post-surgical specimens derived from different grade human gliomas. Although all of the glioma analyzed expressed somatostatin receptor mRNA, DEP-1/PTPeta expression was limited to 8 of 22 of the tumors. Culturing seven gliomas, a correlation between the expression of DEP-1/PTPeta and the somatostatin antiproliferative effects was identified. In conclusion we propose that the expression and activation of DEP-1/PTPeta is required for somatostatin inhibition of glioma proliferation.

Somatostatin (SST) controls the proliferation of a variety of cell types. Its effects are mediated by five G protein-coupled receptors (SSTR1-SSTR5), variably expressed in normal and cancer tissues. SST inhibition of cell proliferation can be exploited by both direct and indirect mechanisms: the main direct pathway involves the modulation of phosphotyrosine phosphatase (PTP) activity. Here we show that SST cytostatic activity is mediated by the activation of a receptor-like PTP, named PTPeta. The role of this PTP in the antiproliferative activity of SST in five glioma cell lines (C6, U87MG, U373MG, DBTRG05MG, and CAS1) and in four postsurgical human glioblastoma specimens, has been studied. SST inhibited growth only in C6 and U87MG that express PTPeta. In C6 cells, SST antiproliferative effects were reverted by pretreatment with pertussis toxin and vanadate, indicating the involvement of G proteins and PTPs. The role of PTPeta in the SST inhibitory effects was demonstrated by testing the PTPeta activity: it was increased by SST treatment and paralleled by inhibition of ERK1/2 activation. Since basic fibroblast growth factor-dependent MEK phosphorylation was not affected by SST, we propose a direct effect of SST-activated PTPeta on ERK1/2 phosphorylation. Finally, the SSTR mRNAs were identified in all of the 36 gliomas analyzed, whereas PTPeta expression was found in 33% of cases. Culturing four gliomas, a precise correlation between the expression of PTPeta and the SST antiproliferative effects was identified. In conclusion, in glioma cells, SST antiproliferative activity requires the expression and activation of PTPeta, which directly dephosphorylates ERK1/2.

In this study, we analyzed the intracellular mechanisms leading to basic fibroblast growth factor (bFGF)-dependent production of NO in Chinese hamster ovary (CHO)-K1 cells and a possible physiological role for such an effect. bFGF induces NO production through the activation of the endothelial form of NO synthase (eNOS), causing a subsequent increase in the cGMP levels. In these cells, the activation of eNOS by bFGF is Ca(2+)- and mitogen-activated protein kinase-independent. The translocation of the enzyme from the plasma membrane, where it is located in caveolae bound to caveolin 1, to the cytosol is the crucial step for the synthesis of NO through the eNOS isoform. We demonstrate that bFGF activates a sphingomyelinase to synthesize ceramide, which, in turn, allows the dissociation of eNOS from caveolin 1 and its translocation to the cytosol in the active form, where it catalyzes the synthesis of NO. In fact, drugs interfering with sphingomyelinase activity blocked bFGF activation of eNOS, and an increase in ceramide content was detected after bFGF treatment. Moreover, in fibroblasts derived from patients with Niemann-Pick disease, in which the enzyme is genetically inactive, bFGF is unable to elicit eNOS activation. The NO produced after bFGF treatment, through the activation of guanylyl cyclase and protein kinase G, mediates a mitogen-activated protein kinase-independent cell proliferation. In conclusion, our data show that, in CHO-K1 cells, bFGF regulates the activity of eNOS through a novel intracellular pathway, involving the induction of ceramide synthesis and that the NO released participates in bFGF proliferative activity.

Nitric oxide (NO) is an intracellular and intercellular mediator involved in the modulation of many physiologic and pathologic processes including the regulation of neoangiogenesis. We analyzed the effects of basic fibroblast growth factor (bFGF) on NO production in CHO-K1 cells and the intracellular mechanisms involved. bFGF induces NO production through activation of the endothelial NO synthase (eNOS), causing a subsequent increase in cGMP levels. In most systems, eNOS activation is a Ca(2+)-calmodulin-dependent process. In CHO-K1 cells, NO production by bFGF is Ca(2+) and MAP kinase independent, because it was not reverted by pretreatment with intracellular Ca(2+) chelators or MEK inhibitors. Translocation of the eNOS from the plasma membrane, where it is bound to caveolin 1, to the cytosol is the crucial step in the synthesis of NO. We demonstrate that the cytosolic translocation of eNOS is caused by increased synthesis of ceramide dependent by the bFGF activation of sphingomyelinase. Indeed, in the presence of the sphingomyelinase inhibitors D609 or desipramine, bFGF-dependent NO production is abrogated. To support this evidence we evaluated ceramide concentration using HPLC-electrospray ionization-mass spectrometry in controls and in bFGF-treated cells: after bFGF stimulation, a substantial increase in ceramide levels was observed. These data were further confirmed by the lack of NO production in response to fibroblast growth factor in fibroblasts derived from Niemann Pick patients who genetically lack the enzyme sphingomyelinase. In conclusion, ceramide in CHO-K1 cells is responsible for a novel Ca(2+)/calmodulin-independent mechanism for eNOS activation after fibroblast growth factor stimulation.

This review will focus on advances in electronic and optoelectronic technologies by through the analysis of a full research and industrial application scenario. Starting with the analysis of nanocomposite sensors, and electronic/optoelectronic/mechatronic systems, the review describes in detail the principles and the models for finding possible implementations of Industry 5.0 applications. The study then addresses production processes and advanced detection systems integrating Artificial Intelligence (AI) algorithms. Specifically, the review introduces new research topics in Industry 5.0 about AI self-adaptive systems and processes in electronics, robotics and production management. The paper proposes also new Business Process Modelling and Notation (BPMN) Process Mining (PM) workflows, and a simulation of a complex Industry 5.0 manufacturing framework. The performed simulation estimates the diffusion heat parameters of a hypothesized production-line layout, describing the information flux of the whole framework. The simulation enhances the technological key elements, enabling an industrial upscale in the next digital revolution. The discussed models are usable in management engineering and informatics engineering, as they merge the perspectives of advanced sensors with Industry 5.0 requirements. The goal of the paper is to provide concepts, research topics and elements to design advanced production network in manufacturing industry.

The aim of this study was the characterization of the intracellular effectors of the antiproliferative activity of somatostatin in PC Cl3 thyroid cells. Somatostatin inhibited PC Cl3 cell proliferation through the activation of a membrane phosphotyrosine phosphatase. Conversely, PC Cl3 cells stably expressing the v-mos oncogene (PC mos) were completely insensitive to the somatostatin antiproliferative effects since somatostatin was unable to stimulate a phosphotyrosine phosphatase activity. In PC mos cells basal phosphotyrosine phosphatase activity was also reduced, suggesting that the expression of a specific phosphotyrosine phosphatase was impaired in these transformed cells. We suggested that this phosphotyrosine phosphatase could be r-PTPη whose expression was abolished in the PC mos cells. To directly prove the involvement of r-PTPη in somatostatin’s effect, we stably transfected this phosphatase in PC mos cells. This new cell line (PC mos/PTPη) recovered somatostatin’s ability to inhibit cell proliferation, showing dose-dependence and time course similar to those observed in PC Cl3 cells. Conversely, the transfection of a catalytically inactive mutant of r-PTPη did not restore the antiproliferative effects of somatostatin. PC mos/PTPη cells showed a high basal phosphotyrosine phosphatase activity which, similarly to PC Cl3 cells, was further increased after somatostatin treatment. The specificity of the role of r-PTPη in somatostatin receptor signal transduction was demonstrated by measuring its specific activity after somatostatin treatment in an immunocomplex assay. Somatostatin highly increased r-PTPη activity in PCCl3 and PC mos/PTPη (+300%, P < 0.01) but not in PCmos cells. Conversely, no differences in somatostatin-stimulated SHP-2 activity, (∼ +50%, P < 0.05), were observed among all the cell lines. The activation of r-PTPη by somatostatin caused, acting downstream of MAPK kinase, an inhibition of insulin-induced ERK1/2 activation with the subsequent blockade of the phosphorylation, ubiquitination, and proteasome degradation of the cyclin-dependent kinase inhibitor p27kip1. Ultimately, high levels of p27kip1 lead to cell proliferation arrest. In conclusion, somatostatin inhibition of PC Cl3 cell proliferation requires the activation of r-PTPη which, through the inhibition of MAPK activity, causes the stabilization of the cell cycle inhibitor p27kip1.

Background: Compared with other health areas, the mental health impacts of climate change have received less research attention. The literature on climate change and mental health is growing rapidly but is characterised by several limitations and research gaps. In a field where the need for designing evidence-based adaptation strategies is urgent, and research gaps are vast, implementing a broad, all-encompassing research agenda will require some strategic focus. Methods: We followed a structured approach to prioritise future climate change and mental health research. We consulted with experts working across mental health and climate change, both within and outside of research and working in high, middle, and low-income countries, to garner consensus about the future research priorities for mental health and climate change. Experts were identified based on whether they had published work on climate change and mental health, worked in governmental and non-governmental organisations on climate change and mental health, and from the professional networks of the authors who have been active in the mental health and climate change space. Results: Twenty-two experts participated from across low- and middle-income countries (n = 4) and high-income countries (n = 18). Our process identified ten key priorities for progressing research on mental health and climate change. Conclusion: While climate change is considered the biggest threat to global mental health in the coming century, tackling this threat could be the most significant opportunity to shape our mental health for centuries to come because of health co-benefits of transitioning to more sustainable ways of living. Research on the impacts of climate change on mental health and mental health-related systems will assist decision-makers to develop robust evidence-based mitigation and adaptation policies and plans with the potential for broad benefits to society and the environment.

Background: : Service user involvement has become increasingly prioritised within health research, and more recently, within mental health and psychosocial support (MHPSS). However, there is limited exploration of service user involvement in the development of lay-delivered MHPSS psychological interventions. The aim of this research was to investigate how service users have been involved in the development of lay-delivered psychological interventions for populations affected by humanitarian crises. Methods: : Thirteen semi-structured interviews were conducted with respondents involved in randomized controlled trials (RCTs) of lay-delivered MHPSS psychological interventions, either as principal investigators or as focal points for service user involvement. Thematic data analysis used was used to analyse the data. Results: : There was a common perception that service user involvement is vital to the development of lay-delivered psychological interventions, but there was concern about how that happened in practice. Respondents desired to increase service user involvement, but they either did not know how to do this into practice or felt that they lacked the resources to do so. Recommendations were made for strengthening involvement, such as employing service users onto research teams. However, legal difficulties in compensating service users for their work were raised. Conclusion: : Service user involvement was viewed as vital in the development of lay delivered psychological interventions, but remains predominantly tokenistic, partly due to limited guidance, time, and finances. Guidelines could support more meaningful and ethical service user involvement in lay-delivered psychological interventions in areas affected by humanitarian crises.

Social sciences (General) ,H1-99 - Abstract
Qualitative research is increasingly being integrated within the development and evaluation phases of trials of complex health interventions. Qualitative research can complement effectiveness data and provide insights around how context and implementation impact the results of the trial and to what extent interventions fit implementation contexts after evaluation. Several qualitative studies have been conducted at different stages of trials of mental health and psychosocial support interventions for populations affected by adversity such as armed conflict and disasters. However, these qualitative components are usually implemented as disjointed components within the trial. The current protocol aims to provide a shared framework detailing the qualitative components of the CHANGE project trial: a program of work to address alcohol misuse and associated mental health comorbidities among conflict-affected populations in Uganda and Ukraine. In particular, the objectives of the current protocol are (i) to identify the specific qualitative questions and methods that will be undertaken in CHANGE; (ii) characterize the different methodological approaches to analyzing the data; and (iii) explain how each qualitative component within the different work-packages will cumulatively add value to each other over the duration of the CHANGE project. The current protocol will represent a useful template for the integration of serial qualitative research components within complex health interventions in humanitarian settings. Each qualitative components described will undergo formal ethics approval by ethics boards in the United Kingdom, Uganda, and Ukraine. Multiple mechanisms will be in place to ensure rigor and trustworthiness of the research by meeting the criteria of credibility, transferability, dependability, and confirmability.

A major concern in the management of Inflammatory Bowel Disease (IBD) is the absence of accurate and specific biomarkers to drive diagnosis and monitor disease status timely and non-invasively. Fibroblast activation protein (FAP) represents a hallmark of IBD bowel strictures, being overexpressed in stenotic intestinal myofibroblasts. The present study aimed at evaluating the potential of circulating FAP (cFAP) as an accessible blood biomarker of IBD. Quantitative determination of cFAP was performed by enzyme-linked immunosorbent assay on plasma samples prospectively collected from patients with IBD and control subjects. A discrimination model was established on a training set of 50% patients and validated on independent samples. Results showed that cFAP concentration was reduced in patients with IBD when compared to controls (p < 0.0001). Age, sex, smoking, disease location and behavior, disease duration and therapy were not associated with cFAP. The sensitivity and specificity of cFAP in discriminating IBD from controls were 70 and 84%, respectively, based on the optimal cutoff (57.6 ng mL−1, AUC = 0.78). Predictions on the test set had 57% sensitivity, 65% specificity, and 61% accuracy. There was no strong correlation between cFAP and routine inflammatory markers in the patients' population. A subgroup analysis was performed on patients with Crohn's disease undergoing surgery and revealed that cFAP correlates with endoscopic mucosal healing. In conclusion, cFAP deserves attention as a promising blood biomarker to triage patients with suspected IBD. Moreover, it might function as a biomarker of post-operative remission in patients with Crohn's disease.

Negli anni recenti, il progresso tecnologico delle infrastrutture ed applicazioni informatiche ha permesso lo sviluppo di nuovi sistemi capaci di fornire analisi ed informazioni con precisione e dettagli inediti. Tali sistemi sono alimentati tramite dati raccolti dalle più diverse fonti interconnesse tra loro. Le informazioni che si posso trarre da questi database hanno un valore molto grande per la loro capacità di restituire la descrizione di un fenomeno, di una persona o di una comunità. In questo lavoro si pone l’attenzione sui dati non personali ovvero quelli generati nell’ambito dell’Internet of Things - IoT nel settore pubblico e privato. Si tratta di aspetti che solo di recente sembrano aver avuto la giusta attenzione e che recano con sé nuove problematiche di natura giuridica, economica e tecnologica. Per poter correttamente porre le basi della discussione, si deve procedere all’indagine della natura di tali dati e delle ragioni giuridiche della loro tutela nonché all’esame di modelli economici e di mercato di valorizzazione degli stessi.

This article describes a prototype cross platform based on intelligent switching of Virtual Private Network (VPN) communications by means of artificial intelligence algorithms able to identify and classify attack risks in self-learning mode by analysing the traffic logs of the system. The platform is also suitable for disaster recovery, data migration and ensures virtualization of communications between nodes in case of risk detection. In order to test the models and evaluate the accuracy of the AI algorithms for risk detection and classification, a number of cyberattack scenario have been simulated. The proposed platform implements Cassandra Big Data system interfacing with supernodes enabling data migration, security and disaster recovery. By comparing the performance of different AI algorithms, the results show that a XGBoost-based algorithm is the most efficient and accurate method for cyberattacks prevention, showing a remarkable ability of classifying and identifying characteristic patterns of the most representative traffic log variables. The research work has been carried out within the framework of a research industry project.

This search following the Sicily, the largest island in the Mediterranean Sea (25,460 sq km) and a self-governing Region, located in the southernmost part of Italy, has at least four tourist-related airports, sited between the eastern and western coast, separated from each other by a vast territory without efficient transport links and suffering from many diverse environmental problems. Utilizing a desk search methodology based on GIS software, this paper discusses the impact upon the regional development of the tourist traffic of the Trapani Airport situated in the westernmost part of Sicily. Ultimately it analyzes the critical role of connectivity and accessibility in the development of the area and tourism, seeking a maximum involvement of stakeholders. The recent growth of low-cost carriers have had a definite impact on the economic growth of the entire territory, where those choices could determine the life or the death of firms and, inevitably, their annual incomes. Tourism and connectivity are strictly related, thus showing deficiencies of the area in terms of accessibility, as well as the trade-offs between the different government (central and local) investment policies and the specific benefits emerging from the airport in the regional mobility.

Il contributo prende in considerazione le implicazioni economico-giuridiche relative all’utilizzo degli algoritmi automatici per le decisioni. Gli algoritmi automatizzati possono sostituirsi ai decisori creando dei contratti, modellando il negozio giuridico, disponendo delle obbligazioni per le parti. Chiaramente si pone la questione degli effetti giuridici di tali decisioni sulle parti e i terzi, e, fatto ancora più grave, si manifestano dei rischi di sostenibilità sistemica. Infatti, la crescita del numero delle decisioni pone delle questioni assai rilevanti in termini di crescita della probabilità di crisi e di manifestazione di avvenimenti avversi. Occorre allora essere attenti alla modellistica metrica utilizzata per analizzare l’impatto delle decisioni automatizzate sia a livello sistemico che nelle posizioni giuridiche dei singoli che possano venire coinvolti ed evitare effetti discriminatori o distorsivi. In questo senso vengono proposti in modo dialettico il metodo gaussiano e il metodo black swan. Il metodo gaussiano impedisce di considerare eventi altamente improbabili eppure distruttivi. Il metodo black swan consente di avere degli strumenti per valutare l’altamente improbabile. Gli algoritmi decisionali possono annullare la stabilità dei sistemi giuridici ed economici e minarne le basi introducendo nuovi paradigmi di funzionamento. Occorre allora accompagnare l’applicazione degli algoritmi automatici con modelli di governance e regolazioni di diritto che siano in grado di ridurre il rischio di eventi avversi distruttivi, di tutelare i contraenti e garantire la sostenibilità del sistema anche alla luce dei diritti individuali e sociali di ciascuno.

Abstract The distinction between natural and human-made disasters is ingrained in everyday language. Disaster scientists have long been critical of this dichotomy. Nonetheless, virtually no attention has been paid to how disaster survivors conceptualize the causes of the disasters they experience. In this mixed-methods longitudinal study, 112 survivors of the 2016–2017 Central Italy earthquakes completed questionnaires 3 and 16 months following the earthquakes, with the aim of assessing attributions of blame for the earthquake damage. In-depth interviews were also conducted with 52 participants at the 3-month mark to explore representations of causation for the earthquake damage. The distinction between disasters caused by nature and disasters caused by humans was not supported by survivors of the earthquake. In the longitudinal surveys, building firms and the State were assigned as much blame as nature for the earthquake damage, at both 3 months and 16 months after the earthquakes. Corroborating this complexity, in the interviews, the causes of the earthquake damage, rather than being understood as purely natural, were perceived as a complex mosaic composed of political, technological, natural, and moral factors. This empirical work shows that disaster survivors combine both nature-based and human-based explanations of disasters, rather than subscribing to one or the other. These findings have practical implications for disaster risk reduction and response.

This paper merges new research topics in Industry 5.0 using the Business Process Modeling and Notation (BPMN) approach able to integrate Artificial Intelligence (AI) in production processes. The goal is to provide an innovative approach to model production management in industry, adopting a new “proof of concept” of advanced Process Mining (PM) automatizing decisions and optimizing machine setting and maintenance interventions. Advanced electronic sensing and actuation systems, integrating supervised and unsupervised AI algorithms, are embedded in the PM model as theoretical process workflows suggested by a Decision Support System (DSS) engine enabling an intelligent decision-making procedure. The paper discusses, as examples, two theoretical models applied to specific industry sectors, such as food processing and energy production. The proposed work provides important elements of engineering management related to the digitalization of production process matching with automated control systems setting production parameters, thus enabling the self-adapting of product quality supervision and production efficiency in modern industrial systems.

Aquaporin-9 (AQP9) is a facilitator of glycerol and other small neutral solute transmembrane diffusion. Identification of specific inhibitors for aquaporin family proteins has been difficult, due to high sequence similarity between the 13 human isoforms, and due to the limited channel surface areas that permit inhibitor binding. The few AQP9 inhibitor molecules described to date were not suitable for in vivo experiments. We now describe the characterization of a new small molecule AQP9 inhibitor, RG100204 in cell-based calcein-quenching assays, and by stopped-flow light-scattering recordings of AQP9 permeability in proteoliposomes. Moreover, we investigated the effects of RG100204 on glycerol metabolism in mice. In cell-based assays, RG100204 blocked AQP9 water permeability and glycerol permeability with similar, high potency (~5 × 10−8 M). AQP9 channel blocking by RG100204 was confirmed in proteoliposomes. After oral gavage of db/db mice with RG100204, a dose-dependent elevation of plasma glycerol was observed. A blood glucose-lowering effect was not statistically significant. These experiments establish RG100204 as a direct blocker of the AQP9 channel, and suggest its use as an experimental tool for in vivo experiments on AQP9 function.

Chronic hepatitis (CH) of dysmetabolic or viral etiology has been associated with poor prognosis in patients who experienced the severe acute respiratory coronavirus virus-2 (SARS-Cov-2) infection. We aimed to explore the impact of SARS-Cov-2 infection on disease severity in a group of patients with CH. Forty-two patients with CH of different etiology were enrolled (median age, 56 years; male gender, 59%). ACE2 and TMPRSS2 were measured in plasma samples of all patients by ELISA and in the liver tissue of a subgroup of 15 patients by Western blot. Overall, 13 patients (31%) experienced SARS-Cov-2 infection: 2/15 (15%) had CHB, 5/12 (39%) had CHC, and 6/15 (46%) had non-alcoholic fatty liver disease (NAFLD). Compared to viral CH patients, NAFLD subjects showed higher circulating ACE2 levels (p = 0.0019). Similarly, hepatic expression of ACE2 was higher in subjects who underwent SARS-Cov-2 infection compared to the counterpart, (3.24 ± 1.49 vs. 1.49 ± 1.32, p = 0.032). Conversely, hepatic TMPRSS2 was significantly lower in patients who experienced symptomatic COVID-19 disease compared to asymptomatic patients (p = 0.0038). Further studies are necessary to understand the impact of COVID-19 in patients with pre-existing liver diseases.
