Clinical Recommendations for the Diagnosis and Treatment of Chronic Myeloid Leukemia

This article is the 4th edition of the recommendations for the diagnosis and treatment of chronic myeloid leukemia. The group of authors reviewed and discussed relevant new publications, and included the significant remarks and comments of experts. Particular attention was paid to the control of risk factors for the development of arterial vascular events and their prevention, and adverse effects of the long-term therapy with tyrosine kinase inhibitors, which were being increasingly reported in recent years

Biopsy of Lungs and Pleura in Hematologic Center

Background & Aims. Morphological, immunohistochemical, immunophenotypic, cytogenetic, molecular and genetic and other examinations of tissues affected by oncohematological diseases are obligatory. The aim of this paper is to evaluate findings of lung and pleura biopsies in different medical conditions using two basic techniques: thoracoscopy and diagnostic thoracotomy. Methods. Results of morphological examination of lung lesions in patients hospitalized in the Hematology Research Center under the Ministry of Health of the Russian Federation are presented. From 2004 till 2014, 76 biopsies of lung and/or parietal pleura were performed in 73 patients aged 19–77 years via thoracoscopic (48) and/or thoracotomic (28) approach. Results. No thoracoscopy- and thoracotomy-related complications were observed. Bioptate examinations proved to be informative in 66 (86.7%) patients. Lung lesions were most common in lymphoproliferative diseases. Lung involvement in cancer or metastases was twice as common as it has been expected before the biopsy. On the contrary, expected tuberculosis nature of lung lesions in 5 patients was confirmed only in 2 of them. In 18 cases (23.7 %), the cause of lung lesion was other than the expected one, and appropriate adjustments of the therapy were made. Conclusion. New less invasive methods of biopsy combined with complex laboratory diagnosing comply with current requirements and permit making a correct diagnosis of a pathological process located in lungs

137 ancient human genomes from across the Eurasian steppes.

For thousands of years the Eurasian steppes have been a centre of human migrations and cultural change. Here we sequence the genomes of 137 ancient humans (about 1× average coverage), covering a period of 4,000 years, to understand the population history of the Eurasian steppes after the Bronze Age migrations. We find that the genetics of the Scythian groups that dominated the Eurasian steppes throughout the Iron Age were highly structured, with diverse origins comprising Late Bronze Age herders, European farmers and southern Siberian hunter-gatherers. Later, Scythians admixed with the eastern steppe nomads who formed the Xiongnu confederations, and moved westward in about the second or third century BC, forming the Hun traditions in the fourth-fifth century AD, and carrying with them plague that was basal to the Justinian plague. These nomads were further admixed with East Asian groups during several short-term khanates in the Medieval period. These historical events transformed the Eurasian steppes from being inhabited by Indo-European speakers of largely West Eurasian ancestry to the mostly Turkic-speaking groups of the present day, who are primarily of East Asian ancestry
