Investing in school systems: conceptualising returns on investment across the health, education and social protection sectors.

Public policies often aim to improve welfare, economic injustice and reduce inequality, particularly in the social protection, labour, health and education sectors. While these policies frequently operate in silos, the education sphere can operate as a cross-sectoral link. Schools represent a unique locus, with globally hundreds of millions of children attending class every day.

A positive consequence of the COVID-19 pandemic: how the counterfactual experience of school closures is accelerating a multisectoral response to the treatment of neglected tropical diseases.

Global access to deworming treatment is one of the public health success stories of low-income countries in the twenty-first century. Parasitic worm infections are among the most ubiquitous chronic infections of humans, and early success with mass treatment programmes for these infections was the key catalyst for the neglected tropical disease (NTD) agenda. Since the launch of the 'London Declaration' in 2012, school-based deworming programmes have become the world's largest public health interventions.

The Broader Economic Value of School Feeding Programs in Low- and Middle-Income Countries: Estimating the Multi-Sectoral Returns to Public Health, Human Capital, Social Protection, and the Local Economy.

Globally, there are 370 million children receiving school meals every day. Coverage is least in low-income countries, where the need is greatest and where program costs are viewed as high in comparison with the benefits to public health alone. Here we explore the policy implications of including the returns of school feeding to other sectors in an economic analysis.

Establishing Global School Feeding Program Targets: How Many Poor Children Globally Should Be Prioritized, and What Would Be the Cost of Implementation?

The creation of Human Capital is dependent upon good health and education throughout the first 8,000 days of life, but there is currently under-investment in health and nutrition after the first 1,000 days. Working with governments and partners, the UN World Food Program is leading a global scale up of investment in school health, and has undertaken a strategic analysis to explore the scale and cost of meeting the needs of the most disadvantaged school age children and adolescents in low and middle-income countries globally. Of the 663 million school children enrolled in school, 328 million live where the current coverage of school meals is inadequate (<80%), of these, 251 million live in countries where there are significant nutrition deficits (>20% anemia and stunting), and of these an estimated 73 million children in 60 countries are also living in extreme poverty ( View Article and Find Full Text PDF

The Role of Health in Education and Human Capital: Why an Integrated Approach to School Health Could Make a Difference in the Futures of Schoolchildren in Low-Income Countries.

Healthy students learn better, yet most current investments in schoolchildren focus on education and learning while largely neglecting the health of the learner. Some school-based interventions, such as school feeding and deworming, are already successfully targeted at this age-group, but the efficiency and cost-effectiveness of such programs could be greatly enhanced by better integrated delivery alongside other priority health interventions. A symposium at the society's 68th annual meeting launched a process to explore how integrated delivery of school-based interventions can address prevalent health conditions in school-age children.

Influence of enzymatic hydrolysis on the allergenic reactivity of processed cashew and pistachio.

Cashew and pistachio allergies are considered a serious health problem. Previous studies have shown that thermal processing, pressurization and enzymatic hydrolysis may reduce the allergenic properties of food by changing the protein structure. This study assesses the allergenic properties of cashew and pistachio after thermal treatment (boiling and autoclaving), with or without pressure (autoclaving), and multiple enzymatic treatments under sonication, by SDS-PAGE, western blot and ELISA, with serum IgE of allergic individuals, and mass spectroscopy.

Detection by real time PCR of walnut allergen coding sequences in processed foods.

A quantitative real-time PCR (RT-PCR) method, employing novel primer sets designed on Jug r 1, Jug r 3, and Jug r 4 allergen-coding sequences, was set up and validated. Its specificity, sensitivity, and applicability were evaluated. The DNA extraction method based on CTAB-phenol-chloroform was best for walnut.

Potential changes in the allergenicity of three forms of peanut after thermal processing.

This study aimed to analyze the influence of thermal processing on the IgE binding properties of three forms of peanut, its effects in the content of individual allergens and IgE cross-linking capacity in effector cells of allergy. Three forms of peanut were selected and subjected to thermal processing. Immunoreactivity was evaluated by means of immunoblot or ELISA inhibition assay.

Determination of β-N-oxalyl-L-α,β-diaminopropionic acid and homoarginine in Lathyrus sativus and Lathyrus cicera by capillary zone electrophoresis.

Background: Lathyrus species as legumes represent an alternative protein source for human and animal nutrition. Heavy consumption of these species can lead to lathyrism, caused by the non-protein amino acid β-N-oxalyl-l-α,β-diaminopropionic acid (β-ODAP). Currently, there is no well-defined level below which β-ODAP is considered non-toxic.

Detection of almond allergen coding sequences in processed foods by real time PCR.

The aim of this work was to develop and analytically validate a quantitative RT-PCR method, using novel primer sets designed on Pru du 1, Pru du 3, Pru du 4, and Pru du 6 allergen-coding sequences, and contrast the sensitivity and specificity of these probes. The temperature and/or pressure processing influence on the ability to detect these almond allergen targets was also analyzed. All primers allowed a specific and accurate amplification of these sequences.

A Novel Proteomic Analysis of the Modifications Induced by High Hydrostatic Pressure on Hazelnut Water-Soluble Proteins.

Food allergies to hazelnut represent an important health problem in industrialized countries because of their high prevalence and severity. Food allergenicity can be changed by several processing procedures since food proteins may undergo modifications which could alter immunoreactivity. High-hydrostatic pressure (HHP) is an emerging processing technology used to develop novel and high-quality foods.

Allergenic properties and differential response of walnut subjected to processing treatments.

The aim of this study was to investigate changes in walnut allergenicity after processing treatments by in vitro techniques and physiologically relevant assays. The allergenicity of walnuts subjected to high hydrostatic pressure and thermal/pressure treatments was evaluated by IgE-immunoblot and antibodies against walnut major allergen Jug r 4. The ability of processed walnut to cross-link IgE on effector cells was evaluated using a rat basophil leukaemia cell line and by skin prick testing.

Real Time PCR to detect hazelnut allergen coding sequences in processed foods.

A quantitative RT-PCR method, employing novel primer sets designed on Cor a 9, Cor a 11 and Cor a 13 allergen-coding sequences has been setup and validated. Its specificity, sensitivity and applicability have been compared. The effect of processing on detectability of these hazelnut targets in complex food matrices was also studied.

School food, politics and child health.

Objective: An analysis undertaken jointly in 2009 by the UN World Food Programme, The Partnership for Child Development and the World Bank was published as Rethinking School Feeding to provide guidance on how to develop and implement effective school feeding programmes as a productive safety net and as part of the efforts to achieve Education for All. The present paper reflects on how understanding of school feeding has changed since that analysis.

Design: Data on school feeding programme outcomes were collected through a literature review.

Effects of autoclaving and high pressure on allergenicity of hazelnut proteins.

Background: Hazelnut is reported as a causative agent of allergic reactions. However it is also an edible nut with health benefits. The allergenic characteristics of hazelnut-samples after autoclaving (AC) and high-pressure (HHP) processing have been studied and are also presented here.

Heat and pressure treatments effects on peanut allergenicity.

Peanut allergy is recognized as one of the most severe food allergies. The aim of this study was to investigate the changes in IgE binding capacity of peanut proteins produced by thermal-processing methods, including autoclaving. Immunoreactivity to raw and thermally processed peanut extracts was evaluated by IgE immunoblot and skin prick test in patients with clinical allergy to peanut.

On the transition to sustainability: an analysis of the costs of school feeding compared with the costs of primary education.

Background: The current food, fuel, and financial crises have highlighted the importance of school feeding programs both as a social safety net for children living in poverty and food insecurity, and as part of national educational policies and plans.

Objective: To examine the costs of school feeding, in terms of both the absolute cost per child and the cost per child relative to overall education expenditure and gross domestic product (GDP) in low-, middle-, and high-income countries.

Methods: Data on the costs of school feeding in different countries were collected from multiple sources, including World Food Programme project data, reports from government ministries, and, where such searches failed, newspaper articles and other literature obtained from internet searches.

Influence of enzymatic hydrolysis on the allergenicity of roasted peanut protein extract.

Background: Peanut allergy is recognized as one of the most severe food allergies. Some studies have investigated the effects of enzymatic treatments on the in vitro immunological reactivity of members of the Leguminosae family, such as the soybean, chickpea and lentil. Nevertheless, there are only a few studies carried out with sera from patients with a well-documented allergy.

Effect of instant controlled pressure drop on IgE antibody reactivity to peanut, lentil, chickpea and soybean proteins.

Background: The use of legume seeds is being expanded in the food industry due to their excellent nutritional and technological properties. However, legumes have been considered causative agents of allergic reactions through ingestion. Previous studies indicated that processing methods combining heat and steam pressure, such as instant controlled pressure drop (DIC®), could decrease allergenicity.

Characterization of lupin major allergens (Lupinus albus L.).

White lupin is considered to be a rich source of protein with a notable content of lysine and is being increasingly used in bakery, confectionery, snacks and pastry products due to its multifunctional properties, in addition to its potential hypocholesterolemic and hypoglycemic properties. However, lupin seed flour has been reported as a causative agent of allergic reactions, especially in patients with allergy to peanut since the risk of immunological cross-reactivity between lupin and peanut is higher than with other legumes. Previously, we had identified two proteins as major lupin allergens (34.
