    The impact of curriculum hierarchies on the development of professional self in teaching: student-teachers of drama negotiating issues of subject status at the interface between drama and English

    At the level of policy the relative ‘value’ of subjects is determined by their official curriculum designation, creating a hierarchy of learning within which particular subjects are categorised as optional to the educational experience of young people. This situation is well-illustrated by the marginalised position of drama in the National Curriculum for England and Wales in which drama appears as an adjunct to the ‘core’ subject English. Yet at school level drama has survived as a discrete and reasonably embedded subject. Drawing on questionnaire and interview data, I investigate the effects of this mismatch on the emergence of pedagogical content knowledge, linked to notions of professional self, in drama student-teachers at one university in the UK. Findings indicate that the student-teachers, whilst not entirely eschewing a less-regulated relationship between the two subjects, view the curriculum for English and its accompanying assessment regime as an inadequate host for drama. In addition, they regard teacher autonomy over curriculum content and pedagogy as indicative of a high degree of professional expertise. This suggests that a case can be made for re-evaluating the nature of the relationship between drama and English and its representation in policy-constructed curricula

    Rapid disease progression in a patient with mismatch repair-deficient and cortisol secreting adrenocortical carcinoma treated with pembrolizumab

    Context: Metastatic adrenocortical carcinoma (ACC) is an aggressive malignancy with a poor prognosis and limited therapeutic options. A subset of ACC is due to Lynch syndrome, an inherited tumour syndrome resulting from germline mutations in mismatch repair (MMR) genes. It has been demonstrated that several cancers characterised by MMR-deficiency are sensitive to immune checkpoint inhibitors that target PD-1. Here, we provide the first report of PD-1 blockade by pembrolizumab in a patient with Lynch syndrome and progressive cortisol-secreting metastatic ACC. Case report: A 58-year old female with known Lynch syndrome who presented with severe Cushing’s syndrome was diagnosed with a cortisol-secreting ACC. Three months following surgical resection and adjuvant mitotane therapy the patient developed metastatic disease and persistent hypercortisolaemia. She commenced pembrolizumab, but her second cycle was delayed due to a transient transaminitis. Computed tomography performed after twelve weeks and 2 cycles of pembrolizumab administration revealed significant disease progression and treatment was discontinued. Seven weeks later, the patient became jaundiced and died rapidly with fulminant liver failure. Conclusion: Treatment of MMR-deficient cortisol-secreting ACC with pembrolizumab may be ineffective due to supra-physiological levels of circulating corticosteroids, which may in turn mask severe drug-induced organ damage

    Bone histomorphometric measures of physical activity in children from Medieval England

    Objectives: Histomorphometric studies show consistent links between physical activity patterns and the microstructure underlying the size and shape of bone. Here we adopt a combined bone approach to explore variation in microstructure of ribs and humeri related to physical activity and historical records of manual labor in skeletal samples of children (n=175) from medieval England. The humerus reflects greater biomechanically induced microstructural variation than the rib which is used here as a control. Variation in microstructure is sought between regions in England (Canterbury, York, Newcastle), and between high- and low-status children from Canterbury. Materials and Methods: Thin-sections were prepared from the humerus or rib and features of bone remodeling were recorded using high-resolution microscopy and image analysis software. Results: The density and size of secondary osteons in the humerus differed significantly in children from Canterbury when compared to those from York and Newcastle. Amongst the older children, secondary osteon circularity and diameter differed significantly between higher and lower status children. Discussion: By applying bone remodeling principles to the histomorphometric data we infer that medieval children in Canterbury engaged in less physically demanding activities than children from York or Newcastle. Within Canterbury, high-status and low-status children experienced similar biomechanical loading until around seven years of age. After this age low-status children performed activities that resulted in more habitual loading on their arm bones than the high-status children. This inferred change in physical activity is consistent with historical textual evidence that describes children entering the work force at this age

    Geochemical signatures of stream sediments within the main geological domains and terranes of North and Central Madagascar

    Geochemical mapping of North and Central Madagascar was carried out using stream sediments at an average density of one sample per 11 km2. Over 50 elements were determined from some 13,300 stream sediments using a sample size fraction of <150 ÎŒm following hot aqua regia digestion. Partially extractable concentrations of six major elements and seven base metals reveal that the Andriamena `greenstone' Belt of the Tsaratanana Complex is geochemically distinct from the other geological divisions within the Precambrian basement of central and northern Madagascar. In particular, this study has shown the detailed spatial distribution of anomalous concentrations of base metals which confirm known areas of chromite mineralisation within the Andriamena Belt. Base metal anomalies also occur in relation to Cretaceous and Neogene volcanic rocks, for example at Nosy Be, and mafic-ultramafic intrusions such as along the Maroala deformation zone. The distribution of anomalous Au in stream sediments showed good correspondence with known gold districts of central and northern Madagascar. Highest concentrations were measured in stream sediments from within the Ampasary-Mananjary (southern Androna-Mandritsara) and Andavakoera (northern margin of North Bemarivo) gold districts. The results of the stream sediment geochemistry show that these new data provide valuable information for current and future mineral exploration and environmental studies in Madagascar, at both regional and local scale
