One significant component of the South African citizenship narrative is centred around the right to basic services and corresponding elements, including dignity and a healthy living environment. This paper employs the concept of infrastructural citizenship, which draws on both infrastructure and citizenship discourses to explore how participants experience and challenge public infrastructure and as such engage with questions surrounding citizenship on an everyday basis (Lemanski, 2019a). Adopting a gendered approach, this paper draws on the empirical case of Quarry Road West, an informal settlement located in Durban, and uses a qualitative methodology. Residents have access to Community Ablution Blocks, free shared sanitation facilities provided by the eThekwini Municipality. This paper argues that restricted access to the facilities undermines perceptions of privacy and health and negatively impacts women individually and in the community. Furthermore, this paper evaluates civic responses to inadequate infrastructure in the form of participation, protest and state-directed actions. As such, it examines how women-state relationships are embedded in public infrastructure, and limitations in regards to infrastructure shape interactions and engagements with the state, their experiences of citizenship, actualisation of rights and identities.

Food access, stability and utilisation are key dimensions of food security at an urban scale. When the majority resided in rural areas, and lived predominantly agrarian lifestyles, it made sense for the state to govern food security through national agricultural ministries, focusing predominantly on the availability dimension of food security. With the transition to a majority urban world, coupled with the food security challenges currently experienced in urban areas, specifically in Africa, these historical policy and governance structures are increasingly inadequate in responding to essential food and nutrition needs. Problematically, urban areas, and specifically urban managers, cite unfunded mandates, and absent authority, as the reasons for not engaging food and nutrition governance responses. This paper argues that this is a false position. Drawing on recent data from household food security and poverty surveys, the paper calls for new and expanded planning and design approaches at the urban scale. The paper argues that spatial planning and urban design principles and actions provide an immediate and effective means through which to engage urban food system questions. Importantly these actions are essential to the transition from the current piecemeal project responses to urban food system inadequacies. Food sensitive planning and urban design is offered as a specific approach that could assist in programming food system-related challenges at the urban scale, responding to conceptual, analytical, organisational and design related dimensions of planning, and in so doing offering a longer term, systematic response to urban food insecurity.

Objectives: Circulating cytokines have been associated with depression, but their detection has limitations, which may be overcome by direct detection of intracellular cytokines (ICCs) after lipopolysaccharide (LPS) stimulation in vitro. This study compared circulating versus LPS-induced inflammatory markers as correlates of subthreshold depressive symptoms.Methods: Secondary data analysis of a cross-sectional insomnia study in healthy community-dwelling older adults was conducted. In 117 participants (≥55 years), plasma tumour necrosis factor-α (TNF-α), interleukin-6 (IL-6), C-reactive protein (CRP) and in vitro LPS-induced monocyte production of IL-6 and TNF-α were assayed. Depressive symptoms were assessed using the clinician-rated Inventory of Depressive Symptomatology (IDS-C). Multivariate linear regression was conducted to test the associations between inflammatory markers and subthreshold depressive symptoms in the entire sample as well as in subgroups stratified into higher and lower inflammation levels.Results: LPS-induced TNF-α (adjusted β = 0.28, p = .04), IL-6 (0.29, p = .03) and TNF-α + IL-6 (0.43, p = .001) significantly positively correlated with subthreshold depressive symptoms only in higher inflammation subgroups. No circulating biomarkers positively correlated in any subgroups. In the entire sample, no biomarkers were significantly associated with subthreshold depressive symptoms.Conclusions: LPS-induced cytokines may be more sensitive correlates of subthreshold depressive symptoms than circulating cytokines, particularly in older adults with higher systemic inflammation.Clinical Trials Registry: ClinicalTrials.gov NCT00280020.
