Shiga toxin-producing Escherichia coli (STEC) is a group of bacteria that causes gastrointestinal illness and occasionally causes large foodborne outbreaks. It represents a major public health concern due to its ability to cause severe illness which can sometimes be fatal. This study was undertaken as part of a rapid investigation into a national foodborne outbreak of STEC O145. On 22 May 2024, United Kingdom (UK) public health agencies and laboratories identified an increase in stool specimens submissions and patients testing positive for Shiga toxin-producing E. coli (STEC). Whole genome sequencing (WGS) identified serotype O145:H28 stx2a/eae belonging to the same five single nucleotide polymorphism (SNP) single linkage cluster as the causative agent. By 3 July 2024, 288 cases had been linked to the cluster. Most cases were adults (87%) and females (57%), 49% were hospitalized with a further 10% attending emergency care. Descriptive epidemiology and analytical studies were conducted which identified consumption of nationally distributed pre-packed sandwiches as a common food exposure. The implicated food business operators voluntarily recalled ready-to-eat sandwiches and wraps containing lettuce on 14 June 2024.

The offspring of women in the poorest socio-economic groups in Western societies have an increased risk of developing non-communicable disease in adult life. Deprivation is closely related to the consumption of a diet with an excess of energy (sugar and fat), salt and a shortage of key vitamins. To test the hypothesis that this diet adversely affects the development and long-term health of the offspring, we have formulated two rodent diets, one with a nutrient profile corresponding to the diet of pregnant women in the poorest socio-economic group (DEP) and a second that incorporated current UK recommendations for the diet in pregnancy (REC). Female rats were fed the experimental diets for the duration of gestation and lactation and the offspring compared with those from a reference group fed the AIN-93G diet. The growth trajectory of DEP and REC offspring was reduced compared with the AIN-93G. The REC offspring diet had a transient increase in adipose reserves at weaning, but by 30 weeks of age the body composition of all three groups was similar. The maternal diet had no effect on the homoeostatic model assessment index or the insulin tolerance of the offspring. Changes in hepatic gene expression in the adult REC offspring were consistent with an increased hepatic utilisation of fatty acids and a reduction in de novo lipogenesis. These results show that despite changes in growth and adiposity maternal metabolic adaptation minimises the adverse consequences of the imbalanced maternal diet on the metabolism of the offspring.

Since the 1970s, advocates have used the term gender neutral to press for legal change in contexts ranging from employment discrimination to marriage equality to public restroom access. Drawing on analyses of all Supreme Court cases, federal courts of appeals cases, and Supreme Court amicus briefs in which the terms gender neutral/neutrality, sex neutral/neutrality, or sexually neutral/sexual neutrality appear, this study examines how US courts have defined gender neutrality and what the scope and limits of its legal application have been. We find that the courts have defined gender neutrality narrowly as facial neutrality, but nonetheless that this limited understanding has transformed some areas of the law, even if it has had little impact on others. Our analysis confirms earlier feminist skepticism about the sufficiency of gender neutrality to guarantee equality but also points to areas in which the law has yet to exploit the idea's significant potential to address discrimination on the basis of sex, sexual orientation, and gender identity.

Iron deficiency is common in pregnant and lactating women and is associated with reduced cognitive development of the offspring. Since iron affects lipid metabolism, the availability of fatty acids, particularly the polyunsaturated fatty acids required for early neural development, was investigated in the offspring of female rats fed iron-deficient diets during gestation and lactation. Subsequent to the dams giving birth, one group of iron-deficient dams was recuperated by feeding an iron-replete diet. Dams and neonates were killed on postnatal days 1, 3 and 10, and the fatty acid composition of brain and stomach contents was assessed by gas chromatography. Changes in the fatty acid profile on day 3 became more pronounced on day 10 with a decrease in the proportion of saturated fatty acids and a compensatory increase in monounsaturated fatty acids. Long-chain polyunsaturated fatty acids in the n-6 family were reduced, but there was no change in the n-3 family. The fatty acid profiles of neonatal brain and stomach contents were similar, suggesting that the change in milk composition may be related to the changes in the neonatal brain. When the dams were fed an iron-sufficient diet at birth, the effects of iron deficiency on the fatty acid composition of lipids in both dam’s milk and neonates’ brains were reduced. This study showed an interaction between maternal iron status and fatty acid composition of the offspring’s brain and suggests that these effects can be reduced by iron repletion of the dam’s diet at birth.

The demographic composition of Kazakhstan after the fall of the Soviet Union presented a dilemma to the new Kazakhstani government: Should it advance a Kazakh identity as paramount, possibly alienating the large non-Kazakh population? Or should it advocate for a non-ethnicized national identity? How would those decisions be made in light of global norms of liberal multiculturalism? And, critically, would citizens respond to new frames of identity? This paper provides an empirical look at supraethnic identity-building in Kazakhstan – that is, at the development of a national identity that individuals place above or alongside their ethnic identification. We closely examine the Assembly of People of Kazakhstan to describe how Kazakhstani policies intersect with theories of nationalism and nation-building. We then use ordered probit models to analyze data from a 2014 survey to examine how citizens of Kazakhstan associate with a “Kazakhstani” supraethnic identity. Our findings suggest that despite the Assembly of People's rhetoric, there are still significant barriers to citizen-level adoption of a supraethnic identity in Kazakhstan, particularly regarding language. However, many individuals do claim an association with Kazakhstani identity, especially those individuals who strongly value citizenship in the abstract.

Nutritional science has traditionally used the reductionist approach to understand the roles of individual nutrients in growth and development. The macronutrient dense but micronutrient poor diets consumed by many in the Western world may not result in an overt deficiency; however, there may be situations where multiple mild deficiencies combine with excess energy to alter cellular metabolism. These interactions are especially important in pregnancy as changes in early development modify the risk of developing non-communicable diseases later in life. Nutrient interactions affect all stages of fetal development, influencing endocrine programming, organ development and the epigenetic programming of gene expression. The rapidly developing field of stem cell metabolism reveals new links between cellular metabolism and differentiation. This review will consider the interactions between nutrients in the maternal diet and their influence on fetal development, with particular reference to energy metabolism, amino acids and the vitamins in the B group.

Recent ground surveys in the Samtskhe-Javakheti region of southern Georgia have investigated a previously undocumented group of sites along a ridge overlooking the upper Kura river valley. Features and artefacts recorded at Varneti suggest long but episodic occupation from the Chalcolithic to the later medieval periods, with prominent phases in the Early to Middle Bronze Age and the Late Bronze Age to Early Iron Age. Varneti has the potential to contribute to understanding economic and strategic aspects of the long-term settlement pattern in the southern Caucasus, especially the interplay between lowland and highland zones. Its position in the landscape, at a transitional point between the river valley and the upland pasture (yayla), may explain its persistent use by agro-pastoral communities that operated in varied cultural situations. The survey results help us frame a series of questions regarding economic and social dynamics at a local and regional scale and the continuity and discontinuity of practice in highland environments through long timespans.

Understanding the underlying mechanisms of recovery from insomnia is an important goal for improving existing treatments. In a randomised controlled trial, 57 participants with insomnia disorder were given either cognitive therapy (CT) or mindfulness-based therapy (MBT) following 4 sessions of CBT. Each participant was assessed on process measures related to CT and MBT. MBT resulted in improvement on mindfulness process measures and the size of the improvement was significantly greater than achieved in the CT condition. Interestingly, CT and MBT both resulted in significant improvement on the cognitive process measures. Treatment outcome on the primary outcome measure (Insomnia Severity Index) was not predicted by type of treatment but was predicted by posttreatment scores on the cognitive process measures. The results suggest that changes in cognitive processes are especially important in treating insomnia, and that there are different therapeutic modalities through which this can be achieved.

Euclid is a Europe-led cosmology space mission dedicated to a visible and near infrared survey of the entire extra-galactic sky. Its purpose is to deepen our knowledge of the dark content of our Universe. After an overview of the Euclid mission and science, this contribution describes how the community is getting organized to face the data analysis challenges, both in software development and in operational data processing matters. It ends with a more specific account of some of the main contributions of the Swiss Science Data Center (SDC-CH).

The genus Acanthobothrium van Beneden, 1850, seems to be in a state of slight confusion due, possibly, to some inadequate descriptions which have led to subsequent misidentifications of some of the species. The type species A. coronatum was first recorded and very briefly described by Rudolphi (1819) as Bothriocephalus coronatus from ‘Squali stellaris, Squali squatinus and Torpedinis marmoratae“. Since then specimens have been assigned to this species which probably belong elsewhere; the list of synonyms and the host records are extensive. Baer (1948) divided the species of the genus into two groups, namely, those parasitic in sharks and those in rays. This seems to be a reasonable distinction as specificity is very marked in cestodes and especially in those of elasmobranchs. It was thought that a detailed study of the type species, presented here, would be a useful preliminary to a consideration of the genus as a whole.

Specimens of A. coronatum were obtained from the spiral valve of Scyliorhinus stellaris (L.) caught in Cardigan Bay in July 1956 and at Plymouth in August 1958 and August and September 1959. The number of worms, complete with scoleces varied from 6 to 10 per fish and in one instance 14. Many fragments of two to three proglottids and many individual proglottids were also present. The scoleces were attached in the first turn of the spiral valve and the strobila adhered feebly along the whole length, sometimes as far back as the rectal gland, leaving on removal a distinct groove in the mucosa.

This paper describes a preliminary investigation of the extent to which the normalised difference vegetation index (NDVI), derived from satellite optical imagery, can indicate the extent of damage to upland tundra (fruticose lichen and dwarf shrub) vegetation. We combine the results of a previously reported classification of Landsat multispectral scanner imagery from Kol'skiy Poluostrov, Russia, with field measurements of the biomass and spectral reflectance of tundra vegetation. The results show that the NDVI is not strongly influenced by biomass, but that differences in species composition and ground cover are significant. Other workers have concluded that vegetation indices are not useful for boreal forests. It is therefore suggested that the use of the NDVI by itself as an indicator of the state of disturbed vegetation in Arctic regions is not recommended.

Previously we have examined the effects of diets deficient in folic acid ( − F) or folate deficient with low methionine and choline ( − F LM LC) on the relative abundance of soluble proteins in the liver of the pregnant rat. In the present study we report the corresponding changes in the fetal liver at day 21 of gestation. The abundance of eighteen proteins increased when dams were fed the − F diet. When dams were fed the − F LM LC diet, thirty-three proteins increased and eight decreased. Many of the differentially abundant proteins in the fetal liver could be classified into the same functional groups as those previously identified in the maternal liver, namely protein synthesis, metabolism, lipid metabolism and proteins associated with the cytoskeleton and endoplasmic reticulum. The pattern was consistent with reduced cell proliferation in the − F LM LC group but not in the − F group. Metabolic enzymes associated with lipid metabolism changed in both the − F and − F LM LC groups. The mRNA for carnitine palmitoyl transferase were up-regulated and CD36 (fatty acid translocase) down-regulated in the − F group, suggesting increased mitochondrial oxidation of fatty acids as an indirect response to altered maternal lipid metabolism. In the − F LM LC group the mRNA for acetyl CoA carboxylase was down-regulated, suggesting reduced fatty acid synthesis. The mRNA for transcriptional regulators including PPARα and sterol response element-binding protein-1c were unchanged. These results suggest that an adequate supply of folic acid and the related methyl donors may benefit fetal development directly by improving lipid metabolism in fetal as well as maternal tissues.
