Improved hygiene depends on the accessibility and availability of effective disinfectant solutions. These disinfectant solutions are unavailable to many communities worldwide due to resource limitations, among other constraints. Safe and effective chlorine-based disinfectants can be produced via simple electrolysis of salt water, providing a low-cost and reliable option for on-site, local production of disinfectant solutions to improve sanitation and hygiene. This study reports on a system (herein called "Electro-Clean") that can produce concentrated solutions of hypochlorous acid (HOCl) using readily available, low-cost materials. With just table salt, water, graphite welding rods, and a DC power supply, the Electro-Clean system can safely produce HOCl solutions (~1.5 liters) of up to 0.1% free chlorine (i.e.,1000 ppm) in less than two hours at low potential (5 V DC) and modest current (~5 A). Rigorous testing of free chlorine production and durability of the Electro-Clean system components, described here, has been verified to work in multiple locations around the world, including microbiological tests conducted in India and Mexico to confirm the biocidal efficacy of the Electro-Clean solution as a surface disinfectant. Cost estimates are provided for making HOCl locally with this method in the USA, India, and Mexico. Findings indicate that Electro-Clean is an affordable alternative to off-the-shelf commercial chlorinator systems in terms of first costs (or capital costs), and cost-competitive relative to the unit cost of the disinfectant produced. By minimizing dependence on supply chains and allowing for local production, the Electro-Clean system has the potential to improve public health by addressing the need for disinfectant solutions in resource-constrained communities.

Institutional Review Board (IRB) approval was received from Loma Linda University in the US, and Christian Medical College-Vellore in India, in accordance with the declaration of Helsinki, prior to data collection. All study materials were forward and back translated for Tamil, the local language. Phase 1(n = 25) involved audio recorded key-informant interviews and focus groups. Verbatim transcripts were inductively coded, and emerging themes identified. Phase 2 (n = 261) entailed a quantitative survey including demographics, health history, and validated scales measuring mental health symptoms, coping strategies, social support, living situation, and life satisfaction. Data collectors were gender and language matched, research trained, community health nurses.Results: Qualitative themes included: 1) benefits of living in the city, 2) double duty for women doing household work and paid work, 3) challenges of living in the urban environment, 4) advantages of living in the village, 5) struggles associated with village life. Quantitative results: the average Hopkins Symptoms Checklist (HSCL) score of 1.82 (SD = 0.70) exceeded the 1.65 cut-off score for anxiety and depression symptomology. Among participants with elevated HSCL scores (n = 129) the average was markedly elevated (M = 2.39, SD = 0.56). These women were more likely to rely on wishful thinking, religious coping, and reported more post-migration living difficulties, less social support, and less satisfaction with life. Regression analysis further explored variables associated with participant HSCL scores.Conclusion: In this sample of low-income urban-dwelling women depression and anxiety symptomology was elevated. Given the limited mental health workforce and cultural stigmatization of mental health issues, further attention is required.Keywords: India, urban women, post-migration, social support, coping

The metal ion manganese (Mn2+) is equally coveted by hosts and bacterial pathogens. The host restricts Mn2+ in the gastrointestinal tract and Salmonella-containing vacuoles, as part of a process generally known as nutritional immunity. Salmonella enterica serovar Typhimurium counteract Mn2+ limitation using a plethora of metal importers, whose expression is under elaborate transcriptional and posttranscriptional control. Mn2+ serves as cofactor for a variety of enzymes involved in antioxidant defense or central metabolism. Because of its thermodynamic stability and low reactivity, bacterial pathogens may favor Mn2+-cofactored metalloenzymes during periods of oxidative stress. This divalent metal catalyzes metabolic flow through lower glycolysis, reductive tricarboxylic acid and the pentose phosphate pathway, thereby providing energetic, redox and biosynthetic outputs associated with the resistance of Salmonella to reactive oxygen species generated in the respiratory burst of professional phagocytic cells. Combined, the oxyradical-detoxifying properties of Mn2+ together with the ability of this divalent metal cation to support central metabolism help Salmonella colonize the mammalian gut and establish systemic infections.

Abstract Epistaxis management on COVID‐19 patients is concerning for otolaryngologists due to the highly virulence and increased concentration within respiratory droplets and nasal secretions. Authors suggest initial management with oxymetazoline nasal drops and local pressure before considering nasal packing with absorbable material to prevent COVID‐19 transmission to surrounding healthcare workers.
