RESUMEN
Background: Inadequate housing is an important social justice issue that adversely affects health. Methods: Drawing on an extended ethnography case study, this paper presents the results of a resident-led survey to highlight the health consequences of inadequate social housing, as residents wait for a 'fair regeneration' of their social housing 'flats' estate within a gentrifying inner-city Dublin neighbourhood. Results: Four key concerns were identified by residents as part of this analysis: (1) substandard housing conditions which are physically harmful to health; (2) the emotional toll of an unsafe social environment; (3) lack of child friendly and community green spaces; and (4) constrained mobility due to inaccessible housing design. Conclusions: The results highlight the urgent need to place greater priority on the maintenance of the existing social housing stock and demonstrate the need for public housing policies that recognize the quality and quantity of adequate housing provision, where care is at the heart of housing policies. The paper also presents a novel 'City of Care' framework, following the need to develop an ethics of care within cities where public health, community wellbeing, solidarity, residents' empowerment, and social justice principles are at the forefront. Given that housing is an essential contributor to good health, it is now time for a joint public housing and public health agenda to create healthier homes by confronting the everyday impact of inadequate housing to tackle social inequalities more broadly.
RESUMEN
OBJECTIVE: Validate the performance characteristics of two analyte specific, laboratory developed tests (LDTs) for the quantification of SARS-CoV-2 subgenomic RNA (sgRNA) and viral load on the Hologic Panther Fusion® using the Open Access functionality. METHODS: Custom-designed primers/probe sets targeting the SARS-CoV-2 Envelope gene (E) and subgenomic E were optimized. A 20-day performance validation following laboratory developed test requirements was conducted to assess assay precision, accuracy, analytical sensitivity/specificity, lower limit of detection and reportable range. RESULTS: Quantitative SARS-CoV-2 sgRNA (LDT-Quant sgRNA) assay, which measures intermediates of replication, and viral load (LDT-Quant VLCoV) assay demonstrated acceptable performance. Both assays were linear with an R2 and slope equal to 0.99 and 1.00, respectively. Assay precision was evaluated between 4-6 Log10 with a maximum CV of 2.6% and 2.5% for LDT-Quant sgRNA and LDT-Quant VLCoV respectively. Using negative or positive SARS-CoV-2 human nasopharyngeal swab samples, both assays were accurate (kappa coefficient of 1.00 and 0.92). Common respiratory flora and other viral pathogens were not detected and did not interfere with the detection or quantification by either assay. Based on 95% detection, the assay LLODs were 729 and 1206 Copies/mL for the sgRNA and VL load LDTs, respectively. CONCLUSION: The LDT-Quant sgRNA and LDT-Quant VLCoV demonstrated good analytical performance. These assays could be further investigated as alternative monitoring assays for viral replication; and thus, medical management in clinical settings which could inform isolation/quarantine requirements.

Despite policy commitments to support ageing in place, we know very little about the everyday realities and experiences of older people living in different environmental circumstances, with varying personal capabilities. This paper: 1) examines the valued place-based functionings of older people through the use of geo-spatial and in-situ methods, where functionings are defined as states of being and doing, and place-based functionings are defined as places, activities, interactions, routes, and routines that support these beings and doings; and 2) demonstrates the utility of a capability approach by amalgamating the interconnected concepts 'ageing in place' and 'ageing well'. Three in-depth individual experiences of ageing at home in a Dublin (Ireland) suburb show how differing health and mobility challenges are managed, and illustrate how conceptions of ageing well in place can be identified from geographically-grounded lifeworlds. Participants' place-based functionings are identified by combining qualitative and geo-spatial approaches through the use of annotated maps, using data obtained from traditional interviews, go-along interviews, and mapping exercises. Results demonstrate the diversity of place-based functionings valued by each individual, and how functionings are negotiated depending on different needs, wishes, and health or mobility challenges. Results also highlight the importance of supportive environments and social supports in enabling older people to realise their most valued functionings over time, which include being able to get out and about, engage and connect with others, carry out daily tasks and errands confidently, and remain independent. By paying attention to subjectively valued place-based functionings, as well as the specific supports required to sustain them, we can facilitate older people to not just age in place, or age well, but to age - as well as they can - in place.

The emergence of SARS-CoV-2 variants of concern (VOC) requires adequate coverage of vaccine protection. We evaluated whether a SARS-CoV-2 spike ferritin nanoparticle vaccine (SpFN), adjuvanted with the Army Liposomal Formulation QS21 (ALFQ), conferred protection against the Alpha (B.1.1.7), and Beta (B.1.351) VOCs in Syrian golden hamsters. SpFN-ALFQ was administered as either single or double-vaccination (0 and 4 week) regimens, using a high (10 µg) or low (0.2 µg) dose. Animals were intranasally challenged at week 11. Binding antibody responses were comparable between high- and low-dose groups. Neutralizing antibody titers were equivalent against WA1, B.1.1.7, and B.1.351 variants following two high dose vaccinations. Dose-dependent SpFN-ALFQ vaccination protected against SARS-CoV-2-induced disease and viral replication following intranasal B.1.1.7 or B.1.351 challenge, as evidenced by reduced weight loss, lung pathology, and lung and nasal turbinate viral burden. These data support the development of SpFN-ALFQ as a broadly protective, next-generation SARS-CoV-2 vaccine.
