Food prices and the wages of the poor: A cost-effective addition to high-frequency food security monitoring.

The affordability of nutritious food for "all people, at all times" is a critically important dimension of food security. Yet surprisingly, timely high-frequency indicators of food affordability are rarely collected in any systematic fashion despite price volatility emerging as major source of food insecurity in the 21st Century. The 2008 global food crisis prompted international agencies to invest heavily in monitoring domestic food prices in low and middle income countries (LMICs). However, food price monitoring is not sufficient for measuring changes in diet affordability; for that, one must also measure changes either in income or in an income proxy. We propose using the wages of unskilled workers as a cheap and sufficiently accurate income proxy, especially for the urban and rural non-farm poor. We first outline alternative measures of "food wage" indices, defined as wages deflated either by consumer food price indices or novel healthy diet cost indices. We then discuss the conceptual strengths and limitations of food wages. Finally, we examine patterns and trends in different types of real food wage series during well-known food price crises in Ethiopia (2008, 2011 and 2022), Sri Lanka (2022) and Myanmar (2022). In all these instances, food wages declined by 20-30%, often in the space of a few months. In Myanmar, the decline in real wages during 2022 closely matches declines in household disposable income. We strongly advocate tracking the wages of the poor as a timely, accurate and cost-effective means of monitoring food affordability for important segments of the world's poor.

Contributing factors to surgical site infection after tibial plateau leveling osteotomy: A follow-up retrospective study.

OBJECTIVE: To identify factors associated with surgical site infection (SSI) after tibial plateau leveling osteotomy (TPLO). STUDY DESIGN: Retrospective case series. ANIMALS: Dogs (n = 541) that underwent TPLO (n = 659). METHODS: Medical records of dogs that underwent TPLO from 2011-2018 were reviewed. Data collected included perioperative and postoperative antimicrobial administration, stifle inspection, duration of surgery and anesthesia, comorbidities, and development of SSI including timing, microbiological investigation, and implant removal. Referring veterinarians were contacted for all dogs without a recorded return visit. Risk factors for SSI were assessed by using a multivariable logistic regression model built by using a stepwise approach. RESULTS: Surgical site infection was documented in 71 of 659 (11%) TPLO, with methicillin-resistant Staphylococcus pseudintermedius accounting for 20 of 71 (28%) infections. Protective factors against SSI included administration of postoperative antimicrobials (odds ratio [OR] 0.263; 95% CI = 0.157, 0.442) and timing of preoperative antimicrobial administration. Preoperative antimicrobial timing was protective against SSI when it was administered more than 60 minutes before the first incision compared with administration within 30 minutes (OR 0.275; 95% CI = 0.112, 0.676) or within 60 minutes (OR 0.419; 95% CI = 0.189, 0.929) of the first incision. CONCLUSION: Early administration of perioperative antimicrobials and postoperative antimicrobial administration were protective against SSI after TPLO. CLINICAL SIGNIFICANCE: Antimicrobials can influence the risk of SSI after TPLO. Perioperative and postoperative antimicrobial administration timing should be considered to reduce SSI.

In vitro elution of amikacin and Dispersin B from a polymer hydrogel.

OBJECTIVE: To characterize the in vitro elution of amikacin and Dispersin B (ß-N-acetylglucosaminidase) in a degradable hydrogel. STUDY DESIGN: In vitro, prospective study. METHODS: Amikacin (group A; 40 mg/mL), Dispersin B (group D; 70 µg/mL), or combined amikacin and Dispersin B (group AD; 40 mg/mL and 70 µg/mL, respectively) were added to a hydrogel. Ten aliquots per group were incubated in phosphate-buffered saline that was exchanged at 1, 4, 8, 12, and 24 hours and then once daily for 10 days. Eluted amikacin and Dispersin B were quantitated by using an amikacin reagent kit and a Dispersin B enzyme-linked immunosorbent assay kit, respectively. Time point drug concentrations were compared between groups by using repeated-measures analysis of variance, and total drug elution was compared by using an area under the curve calculation. RESULTS: Amikacin alone, Dispersin B alone, and amikacin and Dispersin B combined together underwent rapid elution in the first 24 hours, followed by a gradual decrease over 10 days. The concentration of Dispersin B eluted in group D was higher at 1 day and lower from day 5 to day 10 compared with that in group AD. The concentration of amikacin eluted in group A was higher at 1, 4, and 8 hours and on day 10 and lower on day 1 compared with that in group AD. The total elution of amikacin was greater from group AD compared with that from group A (P = .02). CONCLUSION: Combining amikacin and Dispersin B had an affect on the total elution of amikacin but not Dispersin B. CLINICAL SIGNIFICANCE: The combination of amikacin and Dispersin B in a degradable hydrogel could allow local treatment of complex infections without the requirement for multiple invasive procedures.

Integration of Nutrition Into Extension and Advisory Services: A Synthesis of Experiences, Lessons, and Recommendations.

BACKGROUND: The need for nutrition-sensitive agriculture is well recognized and of growing interest to global development players. Extension and advisory services (EAS), with their established infrastructure, provide a unique opportunity for nutrition interventions to be implemented at scale with significant reach. OBJECTIVE: To assess current integration of nutrition in EAS, document training provided to EAS agents, and identify challenges and opportunities for the integration of nutrition. METHODS: A mixed methodology was used, which included a systematic literature review covering the following databases: PubMed, ISI Web of Science, Agris, Google Scholar, Econlit, and IBSS. In addition, online surveys and semistructured key informant interviews with stakeholders were performed. Data were collected between December 2012 and June 2013. RESULTS: Based on this study, the most common integration of nutrition into EAS is through efforts to increase the availability of nutritious food. The nutrition training of extension agents is often inadequate, particularly in the realm beyond technical agricultural skill. Additionally, a lack of career opportunities discourages EAS agents form engaging with nutrition integration. The major challenges to integrating nutrition into EAS centered on lack of training for agents, unclear organizational mandates, lack of female inclusion, lack of mobility, and systemic challenges between agriculture and nutrition sectors. Key opportunities for integration efforts are engaging communities, creating a demand for nutrition, and use of innovative communications. CONCLUSIONS: This study demonstrates a large degree of variability across programs in the integration and implementation of nutrition activities into EAS, providing differing opinions on the feasibility of integration. Although the need for nutrition-sensitive agriculture is known, and there is agreement that EAS would provide a positive framework, there are still challenges impeding a simple integration of nutrition into EAS as a delivery platform.

Food Insecurity and Perceived Effects of COVID-19 on Livelihoods in Rural Sri Lanka.

BACKGROUND: Little is known about how the COVID-19 pandemic has affected food security and livelihoods in Sri Lanka. OBJECTIVE: This article aims to assess food insecurity, perceived effects of COVID-19, and coping mechanisms among agriculture-based households in rural Sri Lanka. METHODS: We used 2 rounds of panel data from phone surveys (n = 1057 households) conducted in 5 districts. Food insecurity (30-day recall), perceived impacts of COVID-19 (6-month recall), and coping mechanisms (6-month recall) were assessed using a household questionnaire. To assess food insecurity, we used the 8-item Food Insecurity Experience Scale. We tested for differences between T1 (baseline: December 2020-February 2021) and T2 (follow-up: July 2021-September 2021) and explored the association between food insecurity and the perceived effect of COVID-19 on income using a logistic regression model. RESULTS: Food insecurity was highly prevalent (T1: 75%, T2: 80%) but varied across districts. Most respondents were affected by COVID-19 and/or COVID-19-associated mitigation measures (T1: 84%, T2: 89%). Among affected households, commonly reported impacts included those on income (T1: 77%, T2: 76%), food costs (T1: 84%, T2: 83%), and travel (∼90% in both rounds). Agricultural activities were also adversely affected (T1: 64%, T2: 69%). About half of COVID-19-affected households reported selling livestock or assets to meet basic needs. Households whose income was impacted by COVID-19 were more likely to be food insecure (adjusted odds ratio: 2.56, P < .001). CONCLUSIONS: Households in rural Sri Lanka experienced food insecurity and livelihood disturbances during the COVID-19 pandemic. Additional surveys are needed to assess recovery post-COVID-19 and to understand if programs that support livelihoods have been protective.

METHOD: This original article used household level survey data from 2 rounds of phone surveys conducted in 5 districts of Sri Lanka.Using a household-level questionnaire, we recorded experience of food insecurity in the last 30 days, perceived impact of COVID-19, and adopted coping mechanism in the 6 months prior to the survey.We reported statistical means and tested for differences between 2 survey rounds.We also explored association between food insecurity and the perceived effect of COVID-19 on income. RESULTS: Household-level food insecurity was highly prevalent during the pandemic.Households perceived a negative effect of the pandemic on their income and employment sources.Households whose income was impacted by the pandemic were more likely to be food insecure. CONCLUSION: Agriculture-based households in rural Sri Lanka experienced food insecurity and livelihood disturbances during the COVID-19 pandemic.Additional research is needed to assess recovery post COVID-19 and to understand whether livelihood support programs have been protective.

The state of food systems worldwide in the countdown to 2030.

This Analysis presents a recently developed food system indicator framework and holistic monitoring architecture to track food system transformation towards global development, health and sustainability goals. Five themes are considered: (1) diets, nutrition and health; (2) environment, natural resources and production; (3) livelihoods, poverty and equity; (4) governance; and (5) resilience. Each theme is divided into three to five indicator domains, and indicators were selected to reflect each domain through a consultative process. In total, 50 indicators were selected, with at least one indicator available for every domain. Harmonized data of these 50 indicators provide a baseline assessment of the world's food systems. We show that every country can claim positive outcomes in some parts of food systems, but none are among the highest ranked across all domains. Furthermore, some indicators are independent of national income, and each highlights a specific aspiration for healthy, sustainable and just food systems. The Food Systems Countdown Initiative will track food systems annually to 2030, amending the framework as new indicators or better data emerge.

Diagnosing the performance of food systems to increase accountability toward healthy diets and environmental sustainability.

To reorient food systems to ensure they deliver healthy diets that protect against multiple forms of malnutrition and diet-related disease and safeguard the environment, ecosystems, and natural resources, there is a need for better governance and accountability. However, decision-makers are often in the dark on how to navigate their food systems to achieve these multiple outcomes. Even where there is sufficient data to describe various elements, drivers, and outcomes of food systems, there is a lack of tools to assess how food systems are performing. This paper presents a diagnostic methodology for 39 indicators representing food supply, food environments, nutrition outcomes, and environmental outcomes that offer cutoffs to assess performance of national food systems. For each indicator, thresholds are presented for unlikely, potential, or likely challenge areas. This information can be used to generate actions and decisions on where and how to intervene in food systems to improve human and planetary health. A global assessment and two country case studies-Greece and Tanzania-illustrate how the diagnostics could spur decision options available to countries.

Increased Weekly Mean PM2.5, and NO2 Are Associated With Increased Proportions of Lower Airway Granulocytes in Ontario Horses.

Ambient pollution is associated with the development and exacerbation of human asthma, but whether air pollution exposure is associated with lower airway inflammation in horses has not been fully evaluated. The Air Quality Health Index (AQHI) is an online tool used by asthmatic Ontarians to modify their outdoor activity when ambient pollution is high. A single AQHI value, falling on a scale from 1 to 10+, is calculated from measurements of fine particulate matter (PM2.5), nitrogen dioxide (NO2), and ozone (O3). Increased AQHI values predict an increased risk for presenting to a health care provider for assessment of asthma exacerbation, with a time lag of 0-9 days after an increase. Whether ambient air pollution is a risk factor for identifying increased lower airway inflammatory cells on cytologic evaluation of bronchoalveolar lavage fluid (BALF) of horses has not yet been explored. To investigate this relationship, case data including BALF cytology preparations from horses across southern Ontario, Canada, were retrieved from the Guelph Animal Health Laboratory's archives. Spanning the years 2007-2017, 154 cases were identified within a 41- by 30-km area surrounding the cities of Guelph and Kitchener. In 78 of 154 cases, cytologic reevaluation identified increased proportions of one or a combination of BALF neutrophils (mean 5%, range 0-15%), eosinophils (mean 2%, range 0-31%), and mast cells (mean 4%, range 0-10%). To assess the effect of lagged pollutant and temperature exposures in these 78 cases, weekly mean values of AQHI, PM2.5, NO2, O3, and temperature were recorded for the 4 weeks prior to the date of the horse's presentation for respiratory tract evaluation. The relationship between ambient exposures and increased proportions of lower airway granulocytes was evaluated using a case-crossover design. Single unit increases in 2-, and 3-week lagged weekly mean PM2.5 and NO2, were associated, respectively, with an 11% (p = 0.04, 95% confidence interval, CI = 1.01-1.22), and 24% (p = 0.03, 95% CI = 1.08-1.43) greater risk of identifying increased lower airway granulocytes. These findings suggest that exposure to increased ambient pollutants is associated with lower airway inflammation in Guelph and Kitchener area horses.

Leveraging an Implementation- Research Partnership to Improve Effectiveness of Nutrition-Sensitive Programs at the World Food Programme.

BACKGROUND: Nutrition-sensitive programs can accelerate progress in addressing malnutrition. However, evidence gaps exist related to their effectiveness and how to optimize program design and implementation. OBJECTIVE: We present the process the International Food Policy Research Institute and the World Food Programme (WFP) used to develop nutrition-sensitive program guidance and plans for improving program effectiveness and contributing to the evidence base through rigorous evaluations. METHODS: A 5-step process, using principles of design thinking (a systematic, iterative analytical approach to problem solving), was used to develop, test, and refine WFP's nutrition-sensitive guidance. The guidance focuses on improving nutrition outcomes for nutritionally vulnerable groups across the life cycle: women and children in the first 1000 days, preschoolers, schoolchildren, and adolescents. RESULTS: Through iterative consultations, we created WFP's nutrition-sensitive guidance that includes harmonized theories of change across WFP's programs; 7 opportunities to enhance the programs' nutrition-sensitivity; and mapping of these opportunities to WFP programs and key evidence gaps. This guidance has been rolled out to WFP's offices worldwide to support improved nutrition outcomes. Finally, several evaluation designs have been proposed to fill identified evidence gaps. CONCLUSIONS: By leveraging our implementation-research partnership, we expect that WFP's programs will be more effective and cost effective for improving nutrition. This can be assessed through coupling newly designed nutrition-sensitive programs with rigorous evaluations. Evaluation results will be used to refine WFP's nutrition-sensitive guidance and improve their programs globally. This guidance, and creation process, could be useful for others interested in designing nutrition-sensitive programs and increasing program effectiveness for nutrition.

Educating and training a workforce for nutrition in a post-2015 world.

Nearly all countries in the world today are burdened with malnutrition, manifesting as undernutrition, micronutrient deficiencies, and/or overweight and obesity. Despite some progress, efforts to alleviate malnutrition are hampered by a shortage in number, skills, and geographic coverage, of a workforce for nutrition. Here, we report the findings of the Castel Gandolfo workshop, a convening of experts from diverse fields in March 2014 to consider how to develop the capacity of a global cadre of nutrition professionals for the post-2015 development era. Workshop participants identified several requirements for developing a workforce for nutrition, including an ability to work as part of a multisectoral team; communication, advocacy, and leadership skills to engage decision makers; and a set of technical skills to address future challenges for nutrition. Other opportunities were highlighted that could immediately contribute to capacity development, including the creation of a consortium to link global North and South universities, online training modules for middle managers, and practical, hands-on experiences for frontline nutrition workers. Institutional and organizational support is needed to enable workshop recommendations on education and training to be effectively implemented and sustained. The findings from the Castel Gandolfo workshop can contribute to the delivery of successful nutrition-relevant actions in the face of mounting external pressures and informing and attaining the forthcoming Sustainable Development Goals.
