First and second-order constructs were identified from the data and authors' interpretations respectively. Using a health systems lens, third-order constructs explored how the health systems shaped women's experiences of Option B+ and their subsequent engagement in care. Women's experiences of Option B+ services were influenced by their interactions with health workers, which were often reported to be inadequate and rushed, reflecting insufficient staffing or training to address pregnant women's needs. Women's experiences were also undermined by various manifestations of stigma which persisted in the absence of resources for social or mental health support, and were exacerbated by space constraints in health facilities that infringed on patient confidentiality. Sub-optimal service accessibility, drug stock-outs and inadequate tracing systems also shaped women's experiences of care. Strengthening health systems by improving health worker capacity to provide respectful and high-quality clinical and support services, improving supply chains and improving the privacy of consultation spaces would improve women's experiences of Option B+ services, thereby contributing to improved care retention. These lessons should be considered as universal test and treat programmes expand.Octolig, a commercially available (a polyethylene diamine covalently attached to silica gel), was subjected to modifications to incorporate sulfur for enhanced removal of lead ion from aqueous solutions. The basic approach was attempted formation of "ThioOctolig" by the reaction of Octolig with thioacetamide in toluene using a shaker bath for 24 or 48 h or in the presence of 10% HCl (1 h). Our experience was that conversion was limited to about 20% based on sulfur analysi
