“A question of human dignity”. Identifying solutions to improve WASH for people experiencing homelessness. A case study from Germany

Urban poverty and homelessness keep growing while investments in health-promoting services and public infrastructure, including drinking water, sanitation and hygiene (WASH) have been decreasing. We used a mixed-method approach to collect data from 45 unhoused individuals in Germany identifying individual, infrastructure-specific, and location-based solutions to improve public WASH. Suggestions included adapting existing infrastructure, opening up existing, but inaccessible and constructing new inclusive infrastructure. Proactive, long-term sustainable solutions were preferred over reactive short-time options. Realizing safe WASH for all requires collaboration between homeless communities, governmental bodies, NGOs, businesses, and sanitation experts.</p

Health Promotion and Homelessness in Germany. Co-defining Challenges, Co-designing Methods, Co-creating Solutions

For people experiencing homelessness, shelters and public restrooms are often the only option to access drinking water, sanitation and hygiene (WASH) services to promote their health. Despite the United Nations Sustainable Development Goal 6 call to “ensure water and sanitation for all” in order to promote health and reduce exposure to infectious disease, and despite the Human Right to Water and Sanitation, the needs of homeless people are not met; WASH inequalities and the resulting burden of disease remain hidden and under-researched in official statistics. This ongoing exploratory project in Bonn, Germany, in collaboration with the City of Bonn, Caritas and Verein für Gefährdetenhilfe aims to i) understand the challenges that people experiencing homelessess in urban areas face with regard to WASH insecurity, by ii) involving people experiencing homelessness as key stakeholders to co-design methods and techniques most suitable to capture the challenges they are facing, and ultimately iii) jointly identify suitable interventions through participatory inclusive mapping.Different activities are being undertaken and include in-depth walking interviews with people experiencing homelessness; joint inspections and spot checks of WASH infrastructure (in)accessible to people experiencing homelessness; mental mapping and participatory mapping; focus group discussions with different relevant stakeholders such as representatives of homeless associations, authorities and social workers supporting and working with people experiencing homelessness.Preliminary findings, the research approach to a high risk, high gain project, challenges faced, and their implications on the progress of the project will be introduced.<br/

Autophagy and ATP-induced anti-apoptosis in antigen presenting cells (APC) follows the cytokine storm in patients after major trauma

Severe trauma and the systemic inflammatory response syndrome (SIRS) occur as a result of a cytokine storm which is in part due to ATP released from damaged tissue. This pathology also leads to increased numbers of immature antigen presenting cells (APC) sharing properties of dendritic cells (DC) or macrophages (MΦ). The occurrence of immature APC appears to coincide with the reactivation of herpes virus infections such as Epstein Barr virus (EBV). The aim of this study was the comparative analysis of the ultrastructural and functional characteristics of such immature APC. In addition, we investigated EBV infection/ reactivation and whether immature APC might be targets for natural killers (NK). Significant macroautophagy, mitochondrial degradation and multivesicular body formation together with the identification of herpes virus particles were morphological findings associated with immature APC. Exogenous stressors such as ATP further increased morphological signs of autophagy, including LC3 expression. Functional tests using fluorescent bacteria proved impaired phagolysosome fusion. However, immature APC were susceptible to NK-92-mediated cytolysis. We found evidence for EBV latency state II infection by detecting EBV-specific LMP1 and EBNA2 in immature APC and in whole blood of these patients. In summary, trauma-induced cytokine storms may induce maturation arrest of APC, promote ATP-induced autophagy, support EBV persistence and impair the degradation of phagocytozed bacteria through inefficient phagolysosome fusion. The susceptibility to NK-mediated cytolysis supports the hypothesis that NK function is likely to contribute to immune reconstitution after major trauma by regulating immature APC, and ATP-induced autophagy and survival

Report from Working Group 3: Beyond the standard model physics at the HL-LHC and HE-LHC

This is the third out of five chapters of the final report [1] of the Workshop on Physics at HL-LHC, and perspectives on HE-LHC [2]. It is devoted to the study of the potential, in the search for Beyond the Standard Model (BSM) physics, of the High Luminosity (HL) phase of the LHC, defined as $3$ ab$^{-1}$ of data taken at a centre-of-mass energy of 14 TeV, and of a possible future upgrade, the High Energy (HE) LHC, defined as $15$ ab$^{-1}$ of data at a centre-of-mass energy of 27 TeV. We consider a large variety of new physics models, both in a simplified model fashion and in a more model-dependent one. A long list of contributions from the theory and experimental (ATLAS, CMS, LHCb) communities have been collected and merged together to give a complete, wide, and consistent view of future prospects for BSM physics at the considered colliders. On top of the usual standard candles, such as supersymmetric simplified models and resonances, considered for the evaluation of future collider potentials, this report contains results on dark matter and dark sectors, long lived particles, leptoquarks, sterile neutrinos, axion-like particles, heavy scalars, vector-like quarks, and more. Particular attention is placed, especially in the study of the HL-LHC prospects, to the detector upgrades, the assessment of the future systematic uncertainties, and new experimental techniques. The general conclusion is that the HL-LHC, on top of allowing to extend the present LHC mass and coupling reach by $20-50\%$ on most new physics scenarios, will also be able to constrain, and potentially discover, new physics that is presently unconstrained. Moreover, compared to the HL-LHC, the reach in most observables will, generally more than double at the HE-LHC, which may represent a good candidate future facility for a final test of TeV-scale new physics
