Abstract S. cinerea (grey sallow) is included in the section Capreae of subgenus Caprisalix (Rechinger, 1964). It is a broadleaved willow, typically a large shrub generally much branched from the base with numerous intercrossing branches. Bark is dark grey, becoming fissured with age. The species forms a broad, rounded crown. Twigs are densely pubescent, remaining so at least until the end of the first year; wood of peeled twigs with long, scattered striae. Leaves very variable, usually ovate or oblanceolate, 2-9 cm long, 1-3 cm wide, dull grey-green and pubescent above or dark green and slightly lustrous. Catkins appearing in advance of the leaves in March and April. Male flowers with 2 free stamens. Capsule up to 10 mm (Meikle, 1984; Newsholme, 1992). S. cinerea is a Eurasian species, common throughout Europe, from the Mediterranean to Scandinavia (including Spain and Portugal, Sicily, Sardinia, Corsica, the Aegean Islands and Turkey). Its range extends eastward to Asia, from the Crimea to the Caucasus, from northern Iran to Siberia, and north of the Caspian and Aral seas to the Chinese border (Jalas and Suominen, 1976; Skvortsov, 1999).It is a useful species in erosion control projects, and to protect marshlands and riverbanks. Because of its early flowering, it is also important for honeybees (Schiechtl, 1996). Hybrids with S. viminalis (S. × calodendron) are grown in the UK, Germany and Denmark to produce biomass as a energy source (McElroy et al., 1983).

The structure of postgraduate hospital training in the UK has changed in the last 20 years: the Calman report brought training in line with European law and the SpR post was created out of the registrar and senior registrar posts. Implementation of the new training was staggered across specialties. ENT was included in the second wave of implementation in October 1995. At the same time, consultant expansion was envisaged.

AbstractThe marsh fritillary Euphydryas aurinia is declining across Europe and is of high conservation interest. Its ecology has been defined and its conservation status assessed primarily from the affinities and populations of young caterpillars in the autumn, before hibernation and high winter mortality. The possibility that caterpillars of E. aurinia can overwinter more than once was investigated on the Isle of Islay, Scotland after caterpillars were found to occur at some locations in the spring despite a pre-hibernation absence. Closely-related species in North America and Northern Europe can prolong larval development by diapausing for a year as does E. aurinia in Scandinavia. Measurements of development and manipulations of distribution confirmed that some caterpillars do extend the life-cycle in Scotland and may occur in areas devoid of larvae in their first year. Caterpillars attempting this life-cycle develop slowly in spring, attain the normal penultimate spring instar and then enter diapause while other caterpillars are pupating. They moult just before diapause, construct highly cryptic webs and on emergence the following spring are 5–6 times heavier than larvae emerging in their first spring, or the equivalent of a month or so ahead. They attain a final, extra instar as larvae in their first spring reach the penultimate instar. Knowledge of this life-cycle is confined in the UK to Islay but its occurrence in this mild climate implies that it is more widespread.Implications for insect conservation Conditions that permit long diapause are probably precise and may not be reflected in recognised qualities of habitat. The species may also be present despite a perceived absence in autumn, the standard period for monitoring. Assessments of the prevalence of the life-cycle and its contribution to the persistence of E. aurinia are required. Populations of E. aurinia are known to fluctuate greatly and do occur below the observation threshold for long periods.

The article covers the role the Great Britain has played as a fourth independent political actor of international relations, along with the U.S., EU and NATO, in the political crisis in Ukraine from its very beginning (2014), and in finding quick and effective ways of solving it. The article also explores the worsening of the bilateral relationship between UK and Russia under the influence of the 2014–2015 Ukrainian crisis, in a wide context of antagonism between the U.S. and Russia. There are several factors introduced in the article which hampered the crisis from the start and which still can be used to improve the bilateral relations in the nearest future. The author scrutinizes the evolution of the Britain's stance on the Ukrainian upheaval at the beginning of 2014, the Crimea annexation/joining perceived as a violation of the international law, Russia's interference in the conflict in the Eastern territories of Ukraine, and the imposing of sever EU and U.S. sanctions against Russia. The article highlights the influence of the Ukrainian crisis on the strengthening of Anglo-American “special relations” and on the revival of the NATO strategic role as a tool to confront Russia not only in this conflict, but also on the world stage. The author tries to assess the scope of damage for the UK–Russia relationship made by the Ukrainian crisis and answer the questions: where has British participation in this crisis boosted the Great Britain's world standing, when can the UK–Russia relations become better again, and what can help improve the relationship between two countries?

Objective.To determine the incidence of arterial thrombotic events (ATE) and venous thromboembolism (VTE) in antineutrophil cytoplasmic antibody–associated vasculitis (AAV).Methods.This is a retrospective cohort study presenting the incidence of ATE (coronary events or ischemic stroke) and VTE [pulmonary embolism (PE) or deep venous thrombosis (DVT)] in patients diagnosed with AAV between 2005 and 2014.Results.There were 204 patients with AAV who were identified. Median followup for surviving patients was 5.8 (range 1–10) years, accounting for 1088 person-years (PY). The incidence of ATE was 2.67/100 PY (1.56 for coronary events and 1.10 for ischemic stroke) and for VTE was 1.47/100 PY (0.83 for DVT only and 0.64 for PE with/without DVT). On multivariate analysis, prior ischemic heart disease (IHD) and advancing age were the only independent predictors of ATE. Among patients without prior IHD or stroke, the incidence of ATE remained elevated at 2.32/100 PY (1.26 for coronary events and 1.06 for ischemic stroke). ATE, but not VTE, was an independent predictor of all-cause mortality. Event rates for both ATE and VTE were highest in the first year after diagnosis of AAV but remained above the population incidence during the 10-year followup period. In comparison to reported rates for the UK population, the event rates in our AAV patients were 15-times higher for coronary events, 11-times higher for incident stroke, and 20-times higher for VTE.Conclusion.Patients with AAV have a high incidence of arterial and venous thrombosis, particularly in the first year after diagnosis.

Abstract Objectives To describe direct healthcare costs for adults with systemic lupus erythematosus (SLE) in the UK over time and by disease severity and encounter type. Methods Patients aged ≥18 years with SLE were identified using the linked Clinical Practice Research Datalink—Hospital Episode Statistics database from January 2005 to December 2017. Patients were classified as having mild, moderate, or severe disease using an adapted claims-based algorithm based on prescriptions and comorbid conditions. We estimated all-cause healthcare costs and incremental costs associated with each year of follow-up compared with a baseline year adjusting for age, sex, disease severity, and comorbid conditions (2017 UK pounds). Results We identified 802 patients; 369 (46.0%) with mild, 345 (43.0%) moderate, and 88 (11.0%) severe disease. The mean all-cause cost increased in the 3 years before diagnosis, peaked in the first year after diagnosis and remained high. Adjusted total mean annual increase in costs per patient was £4476 (95% confidence interval £3809–5143) greater in the year of diagnosis compared with the baseline year (p < 0.0001). The increase in costs per year were 4.7-fold and 1.6-fold higher among patients with severe SLE compared with those with mild and moderate SLE respectively. Primary care utilisation was the leading component of costs during the first year of diagnosis. Conclusion The healthcare costs for patients with SLE in the UK are substantial, remain high after diagnosis and increase with increasing severity. Future research should assess whether earlier diagnosis and treatment may reduce disease severity and associated high healthcare costs.

'Personalised learning' and the value of national assessment data in achieving it have been identified by the UK Secretary of State for Education and Skills as essential for raising educational standards. Employing multilevel analysis, this paper compares children's end of primary school (Key Stage 2) test scores with those they achieved in comparable test papers taken in each term of their first year of secondary school. The paper questions the reliability of national assessment data in respect of the performance of individual children, their predictive validity and thus their value in contributing to the provision of 'personalised learning'.
