This timely book presents a wide-ranging review of Arctic environmental change in response to global warming, and gives a broad insight into the transformation of the Arctic which we can expect during the next century. It is in high northern latitudes that we can expect to observe global warming at its most powerful, making it a natural laboratory where climate changes and their impacts can be monitored and studied more readily than elsewhere in the world. Fourteen authoritative reviews cover the predictions of warming rates by General Circulation Models; variabilities in atmospheric circulation and moisture flux; the dynamics of the polar vortex in the Arctic and its role in ozone loss; the countervailing influence of air pollution in reducing solar irradiance; and the impact of climatic change on Arctic terrestrial and marine ecosystems. Also detailed are the thermohaline circulation of the ocean, the extent and thickness of sea ice, the sizes of glaciers and ice sheets, and the extent of permafrost. Moving to past changes, the records from Greenland ice cores and deep ocean drilling are reviewed for what they tell us about past climates and glaciation in the Arctic., The book paints a vivid and disturbing picture of the enhanced warming that can be expected in the Arctic relative to lower latitudes, and of the major impacts that this will have on the northern cryosphere. It will be an invaluable reference for anyone seeking a greater understanding of the factors and processes affecting the arctic environment, which may ultimately have a major impact on global climatic change

Abstract : Introduction: Primary HPV screening will be implemented into the English Cervical Screening Programme by 2019. Its impact upon women referred to colposcopy, with negative cytology but persistently positive high-risk HPV (hrHPV), remains unreported from UK Sentinel sites. HPV primary screening was introduced in Sheffield, UK in April 2013; this paper reports its impact on the service. Methods: A retrospective cohort study was performed from June 2014 to July 2016 at the Jessop Wing Colposcopy Unit, Sheffield. UK. Data were obtained from the pathology and colposcopy databases and cross-referenced with case-notes and pathology results for women referred with persistently positive hrHPV, cytology negative samples. Patient demographics, hrHPV genotype, biopsy rates, histological diagnoses, management, and outcomes were collected and baseline statistics performed. Results: During the study 1076 women were seen. Most frequent hrHPV genotypes were: hrHPV other, 41%; and HPV16, 33%. The majority (72%) were found to have normal colposcopy; 28% had an abnormal colposcopic assessment (11% low-grade; 11% high-grade; 6% inadequate). The majority were discharged (83%) and only 5% underwent LLETZ. No cancers were detected. High-grade cervical intraepithelial neoplasia (CIN) was found in 7%; overall risk of CIN2 was 1/29; 1/30 for CIN3. Presence of HPV16 was associated with a significantly higher risk of high-grade CIN; 1/9. Conclusion: This is the first study to report results for women referred to colposcopy with cytology negative, persistently positive hrHPV. Disease prevalence is low, although women with HPV16 have a significantly higher likelihood of high-grade disease compared to other HPV subtypes. Abstract : This is the first study to report results from a Sentinel Site for women referred to colposcopy who have negative cytology but are positive for hrHPV. Undertaking colposcopy in a population with such a low prevalence of disease is challenging and can impact on the confidence of the colposcopist
