    BACKGROUND: Little is known about the iodine status of lactating mothers and their infants during the first 6 mo postpartum or, if deficient, the amount of supplemental iodine required to improve status. OBJECTIVE: The objective was to determine maternal and infant iodine status and the breast-milk iodine concentration (BMIC) over the first 6 mo of breastfeeding. DESIGN: A randomized, double-blind, placebo-controlled supplementation trial was conducted in lactating women who received placebo (n = 56), 75 ÎŒg I/d (n = 27), or 150 ÎŒg I/d (n = 26) after their infants' birth until 24 wk postpartum. Maternal and infant urine samples and breast-milk samples were collected at 1, 2, 4, 8, 12, 16, 20, and 24 wk. Maternal serum thyrotropin and free thyroxine concentrations were measured at 24 wk. RESULTS: Over 24 wk, the median urinary iodine concentration (UIC) of unsupplemented women and their infants ranged from 20 to 41 ÎŒg/L and 34 to 49 ÎŒg/L, respectively, which indicated iodine deficiency (ie, UIC < 100 ÎŒg/L). Mean maternal UIC was 2.1-2.4 times higher in supplemented than in unsupplemented women (P < 0.001) but did not differ significantly between the 2 supplemented groups. BMIC in the placebo group decreased by 40% over 24 wk (P < 0.001) and was 1.3 times and 1.7 times higher in women supplemented with 75 ÎŒg I/d (P = 0.030) and 150 ÎŒg I/d (P < 0.001), respectively, than in unsupplemented women. Thyrotropin and free thyroxine did not differ significantly between groups. CONCLUSION: BMIC decreased in the first 6 mo in these iodine-deficient lactating women; supplementation with 75 or 150 ÎŒg I/d increased the BMIC but was insufficient to ensure adequate iodine status in women or their infants. The study was registered with the Australian New Zealand Clinical Trials Registry as ACTRN12605000345684

    Environmental enteric dysfunction and child stunting

    In 2017, an estimated 1 in every 4 (23%) children aged < 5 years were stunted worldwide. With slow progress in stunting reduction in many regions and the realization that a large proportion of stunting is not due to insufficient diet or diarrhea alone, it remains that other factors must explain continued growth faltering. Environmental enteric dysfunction (EED), a subclinical state of intestinal inflammation, can occur in infants across the developing world and is proposed as an immediate causal factor connecting poor sanitation and stunting. A result of chronic pathogen exposure, EED presents multiple causal pathways, and as such the scope and sensitivity of traditional water, sanitation, and hygiene (WASH) interventions have possibly been unsubstantial. Although the definite pathogenesis of EED and the mechanism by which stunting occurs are yet to be defined, this paper reviews the existing literature surrounding the proposed pathology and transmission of EED in infants and considerations for nutrition and WASH interventions to improve linear growth worldwide

    Leveraging agriculture for nutrition in South Asia and East Africa: examining the enabling environment through stakeholder perceptions

    South Asia and sub-Saharan Africa are the two regions of the world with the highest concentration of undernutrition. The majority of the nutritionally vulnerable populations in both regions is dependent in some way upon agriculture as a primary source of livelihood. The agriculture sector and wider agri-food system is considered to be central to sustained progress in reducing undernutrition – and yet not enough is known about how to unleash this potential. Recent scoping assessments have also revealed a paucity of information on wider political, institutional and policy-related challenges relating to the agriculture-nutrition nexus globally. Contextualized research into policy processes and the political economy of agriculture and nutrition is needed to better characterize “enabling environments” for agriculture to benefit nutrition, and how these environments can be shaped and sustained. This study aims to contribute to filling this gap, by drawing upon evidence from a set of case studies in South Asia (India, Bangladesh and Pakistan) and eastern Africa (Ethiopia, Uganda and Kenya). In synthesizing results across countries, while recognizing important nuance and detail, we conclude by highlighting four key issues to be addressed. First, improving knowledge and perception of undernutrition and its links to agriculture, on the part of agricultural policymakers and programme managers. Second, generating system-wide incentives for decisions and actions to become more pro-nutrition. Third, developing transparent systems of accountability for nutrition-relevant action throughout the agriculture sector, through linking timely and actionable data and evidence with incentives. And fourth, cultivating and strengthening leadership and capacities at different levels, underpinned by adequate financing.UK AidDepartment for International Development (DFID

    Value/s in early childhood education

    Twenty years ago, as an early childhood teacher, I was fortunate to attend a professional development day conference led by the inimitable Professor Tina Bruce. At the conference, Tina asked we early childhood teachers: ‘What one thing would you put your back to the wall for in your job?’ In other words, Tina wanted us to share with one another the values that guide our daily work with young children and their families. An avowed Froebelian, Tina herself subscribes to a very particular set of values (Bruce 2015) and she is not alone. Many early childhood educators over two centuries have been influenced by the principles and philosophy developed by Froebel, the original kindergarten practitioner (Froebel Trust 2018). Indeed, as for so many others, my own initial teacher education was strongly influenced by Froebelian principles which have continued to guide my work in the field for thirty-five years. We live in an era of unprecedented global focus on early childhood development (UNESCO 2017; WHO 2018), in this editorial I revisit Froebel’s principles and I argue that we would be wise to continue to regard them as relevant and valuable touchstones for early childhood education in the twenty-first century

    An analysis of child protection 'standard operating procedures for research' in higher education institutions in the United Kingdom.

    BACKGROUND: Interest in children's agency within the research process has led to a renewed consideration of the relationships between researchers and children. Child protection concerns are sometimes not recognised by researchers, and sometimes ignored. Yet much research on children's lives, especially in health, has the potential to uncover child abuse. University research guidance should be in place to safeguard both researchers and the populations under scrutiny. The aim of this study was to examine university guidance on protecting children in research contexts. METHODS: Child protection Standard Operating Procedures (SOPs) were requested from institutions with Research Assessment Exercise (2008) profiles in the top two quartiles according to published league tables. Procedures were included if they applied across the institution and if they were more extensive than stating the university's general application of the UK Disclosure and Barring Service process. A typology for scoring the SOPs was designed for this study based on the authors' previous work. The typology and the raw data scoring were reviewed independently by each of the team members and collectively agreed. The raw scores were charted and analysed using descriptive statistics. RESULTS: SOPs for research conduct amongst vulnerable groups were sought from 83 institutions. Forty HEIs provided policies which met the inclusion criteria. The majority did not mention children, young people or vulnerable adults as a whole, although children in nurseries and young people in universities were addressed. Only three institutions scored over 50 out of a possible 100. The mean score was 17.4. More than half the HEIs made no reference to vetting/barring schemes in research, only eight universities set out a training programme on child protection. Research was often not mentioned in the SOPs and only six mention children in research, with only two fully recognising the extent of child protection in research. DISCUSSION: There is potential for researchers to recognise and respond to maltreatment of children who participate in research. However, the majority of HEIs do not have an overt culture of safeguarding. There is confusion over what are the roles and responsibilities of HEIs in relation to research that involves children. CONCLUSIONS: The policies that are meant to support and guide research practice, so that children are protected, are in the most part non-existent or poorly developed
