To investigate the intake of iodine in mother–infant pairs.
Design:
An exploratory, cross-sectional study. Iodine intake was estimated using Nutritics nutritional analysis software, following 24-h dietary recall. Iodine-rich foods were grouped and compared between those women who met the UK reference nutrient intake (RNI) for iodine (140 µg/d) and those who did not.
Setting:
Online and telephone questionnaires.
Participants:
Self-selecting caregivers of infants aged 6–12 months.
Results:
Ninety-one mother–infant pairs with a mean (sd) age of 33·2 (4·1) years and 8·4 (1·3) months, respectively, were included. Most mothers were exclusively breast-feeding (54·9 %). The estimated maternal median iodine intake from food and supplements (median 140·3 µg/d, just meeting the UK RNI for women of reproductive age, but not the World Health Organisation (WHO) or British Dietetic Association (BDA) recommendations for lactating women (250 µg/d and 200 µg/d, respectively). Forty-six (50·5 %) of mothers met the UK RNI. Estimated intakes of fish, eggs, cow’s milk and yoghurt/cream/dairy desserts were significantly greater, whilst intakes of plant-based milk alternative drinks were significantly less in mothers who met the RNI for iodine (P < 0·05) compared with those who did not. Infant iodine intake from food was positively correlated with maternal; total iodine intake, iodine intake from all food and iodine intake from dairy foods (Spearman’s rho = 0·243, 0·238, 0·264, respectively; P < 0·05).
Conclusions:
Women in the UK may not consume enough iodine to meet the demands of lactation. Guidance on iodine-containing foods, focussed on intake before and during pregnancy and lactation and mandatory fortification of plant-based milk-alternatives could all serve to avoid deficiency.
We present the first results from a new backend on the Australian Square Kilometre Array Pathfinder, the Commensal Realtime ASKAP Fast Transient COherent (CRACO) upgrade. CRACO records millisecond time resolution visibility data, and searches for dispersed fast transient signals including fast radio bursts (FRB), pulsars, and ultra-long period objects (ULPO). With the visibility data, CRACO can localise the transient events to arcsecond-level precision after the detection. Here, we describe the CRACO system and report the result from a sky survey carried out by CRACO at 110-ms resolution during its commissioning phase. During the survey, CRACO detected two FRBs (including one discovered solely with CRACO, FRB 20231027A), reported more precise localisations for four pulsars, discovered two new RRATs, and detected one known ULPO, GPM J1839 $-$10, through its sub-pulse structure. We present a sensitivity calibration of CRACO, finding that it achieves the expected sensitivity of 11.6 Jy ms to bursts of 110 ms duration or less. CRACO is currently running at a 13.8 ms time resolution and aims at a 1.7 ms time resolution before the end of 2024. The planned CRACO has an expected sensitivity of 1.5 Jy ms to bursts of 1.7 ms duration or less and can detect $10\times$ more FRBs than the current CRAFT incoherent sum system (i.e. 0.5 $-$2 localised FRBs per day), enabling us to better constrain the models for FRBs and use them as cosmological probes.
In this chapter, the subjection of the Israelites in Egypt and their later liberation from oppression is examined with extracts from the Hebrew Torah, and the Greek Septuagint. The vocabulary of servitude of both Hebrew and Greek is discussed through the account of Joseph’s service and disgrace in the house of Potiphar, followed by the suffering of the Israelites, the later descendants of Jacob. The oppression inflicted by the Egyptians and their pharaoh on the Israelites in Egypt is to be seen in their forced labour in making bricks and construction work. Liberation involved leaving the country together, under the leadership of Moses. A final section examines a few further literary texts dating from the Hellenistic and Roman periods that treat related Jewish subjects.
In this chapter tomb paintings join the selection of texts (preserved on stone, papyrus, and leather) to show the role of dependence as a structural feature of pharaonic society. Foreigners were acquired through raiding and warfare, and settled in both existing and new communities. An actual trade in persons is also documented and varying aspects of the experience of such individuals is examined, as they were exploited by those who purchased them or passed them on as gifts. Changes over time in the vocabulary of dependence are discussed, as are the different types of work and production in which such dependents were involved. Non-free dependents were employed on the land, in animal herding, and in artisanal workshops, especially textiles, as well as in the home. The key economic role of Egyptian temples is a constant feature of the period.
This chapter introduces the following corpus of texts from ancient Egypt, and outlines the differing meanings ascribed to slavery and dependence from antiquity to modern times. The terms used for dependents and slaves in the various languages of the texts translated here – Egyptian (Hieroglyphic, Hieratic, Demotic, and Coptic), Greek, and Arabic – are briefly presented, and defining features of the condition of those so labelled are discussed. How and from where such persons were acquired, their life experiences, and the different forms of exploitation in which they were involved are introduced, as are forms of slave resistance and limits to the archaeological and textual evidence available, and so to what we can learn from it.
Covering late antique Egypt into the period of Arab rule, this chapter introduces documents and literary texts translated from Greek, Coptic, and Arabic. In the countryside, coloni joined slaves and dependents at work on the great estates of Byzantine Egypt, while in the cities slavery continued as before. Coptic literature from the same period introduces servitude within Christian monasteries. The writings of Shenoute and Gnostic texts regularly employ the vocabulary of slavery in a negative sense. The trade, employment, and emancipation of slaves continued. Conscripted labour is also documented. Children and adults donated to monasteries represent a new form of sacred servitude. With the Arab conquest of Egypt, war and raiding resurface as important sources of slaves. Nubia and the Near East were again key areas for their acquisition, and slaves are illustrated as active in most areas of life and integrated into the religious life of their owners’ households.
In Roman Egypt, Greek remained the language of rule but the introduction of the Roman legal system and practices resulted in changes within the bureaucracy and an increase in documentation. Declarations were now required for birth, death, taxes, and much else. There were minor changes in the vocabulary of slavery, but in terms of acquisition and use much remained unchanged. There was an active market in slaves who were primarily employed in the home. There is further evidence for slaves in labouring jobs, artisanal roles, in entertainment and sex work. Imperial slaves held some important administrative roles, and slaves might act as business agents in urban settings. Slave labour was little used in agriculture, though the balance between free and unfree changed over time. As earlier, the boundaries between these categories were sometimes blurred. There is evidence, too, for the manumission of slaves. Documents translated in this chapter illustrate the situation.
