Abstract
BACKGROUND Kabuki Syndrome is a rare and genetically heterogenous condition with both ophthalmic and systemic complications and typical facial features. We detail the macular phenotype in two unrelated patients with Kabuki syndrome due to de novo nonsense variants in KMT2D, one novel. A follow-up of 10 years is reported. Pathogenicity of both de novo nonsense variants is analyzed. METHODS Four eyes of two young patients were studied by full clinical examination, kinetic perimetry, short wavelength autofluorescence, full field (ff) ERGs, and spectral-domain optical coherence tomography (SD-OCT). One patient had adaptive optic (AO) imaging. Whole exome sequencing was performed in both patients. RESULTS Both patients had de novo nonsense variants in KMTD2. One patient had c.14843C>G; p. (Ser4948ter) novel variant and the second c.11119C>T; p. (Arg3707ter). Both had a stable Snellen visual acuity of 0.2-0.3. The retinal multimodal imaging demonstrated abnormalities at the fovea in both eyes: hyperreflectivity to blue light and a well-delimited gap-disruption of ellipsoid and interdigitation layer on OCT. The dark area on AO imaging is presumed to be absent for, or with structural change to photoreceptors. The ff ERGs and kinetic visual fields were normal. The foveal findings remained stable over several years. CONCLUSION Kabuki syndrome-related maculopathy is a distinct loss of photoreceptors at the fovea as shown by multimodal imaging including, for the first time, AO imaging. This report adds to the literature of only one case with maculopathy with two additional macular dystrophies in patients with Kabuki syndrome. Although underestimated, these cases further raise awareness of the potential impact of retinal manifestations of Kabuki syndrome not only among ophthalmologists but also other healthcare professionals involved in the care of patients with this multisystem disorder.

Abstract
OBJECTIVE to establish the relationship between quantitative and qualitative parameters of peripheral blood cells(lymphocytes, neutrophilic granulocytes, monocytes, platelets) depending on the type of somatic diseases andannual internal radiation doses from 137Cs in children - residents of radiologically contaminated territories in thelate period after the Chornobyl Nuclear Power Plant (ChNPP) accident. MATERIALS AND METHODS There were 175 children included in the study comprising residents of radiologically con-taminated territories (n = 79) aged from 4 to 18 years. Annual internal radiation doses in children from 137Cs rangedfrom 0.004 to 0.067 mSv. Certain blood parameters were assessed in a comparative mode in children having got theradiation doses up to 0.01 mSv and higher. The comparison group (n = 96) included children living in settlementsnot attributed to the radiologically contaminated ones. Incidence and type of somatic diseases and its impact onquantitative and qualitative changes in blood parameters (i.e. lymphocyte, neutrophilic granulocyte, monocyte, andplatelet count) were studied. The cell size, state of nucleus, membranes and cytoplasm, signs of proliferative anddegenerative processes were taken into account. RESULTS Incidence and type of somatic diseases in children did not depend on the annual internal radiation dose.Number of cases of monocytosis was significantly higher among the children exposed to ionizing radiation than inthe comparison group (16.6 % vs. 7.3 %). There were, however, no correlation between these changes and radiationdoses. Number of activated blood monocytes with cytoplasmic basophilia and residues of nucleoli in nuclei washigher in individuals with internal radiation doses > 0.01 mSv. A direct correlation between the qualitative param-eters of monocytes and internal radiation doses was established (rs = 0.60; р < 0.001), as well as a direct correlationof different strength between qualitative parameters of blood cells, indicating their unidirectional pattern depend-ing on the somatic morbid conditions. Regardless of annual internal radiation dose, there was an increase in thenumber of degenerative and aberrant cells vs. the comparison group (р < 0.05), which could be due to the role ofnon-radiation factors. CONCLUSIONS Results of the assessment of quantitative and qualitative parameters of peripheral blood cells reflect-ed the state of morbid conditions in children and are of a diagnostic value. The identified dose-dependent changesin monocyte lineage of hematopoiesis may be the markers of impact of long-term radionuclide incorporation withfood in children living in environmentally unfavorable conditions after the ChNPP accident.

Abstract
OBJECTIVE Deficiency of adenosine deaminase 2 (DADA2) is a potentially fatal monogenic syndrome characterized by variable manifestations of systemic vasculitis, bone marrow failure, and immunodeficiency. Most cases are diagnosed by pediatric care providers, given the typical early age of disease onset. This study was undertaken to describe the clinical phenotypes and treatment response both in adults and in children with DADA2 in India. METHODS A retrospective analysis of pediatric and adult patients with DADA2 diagnosed at various rheumatology centers across India was conducted. Clinical characteristics, diagnostic findings, and treatment responses were analyzed in all subjects. RESULTS In total, 33 cases of DADA2 were confirmed in this cohort between April 2017 and March 2020. Unlike previous studies, nearly one-half of the confirmed cases presented during adulthood. All symptomatic patients exhibited features of vasculitis, whereas constitutional symptoms and anemia were more common in pediatric patients. Cutaneous and neurologic involvement were common, and 18 subjects had experienced at least one stroke. In addition, the clinical spectrum of DADA2 was expanded by recognition of novel features in these patients, including pancreatic infarction, focal myocarditis, and diffuse alveolar hemorrhage. Treatment with tumor necrosis factor inhibitors (TNFi) was initiated in 25 patients. All of the identified disease manifestations showed marked improvement after initiation of TNFi, and disease remission was achieved in 19 patients. Two cases were complicated by tuberculosis infection, and 2 deaths were reported. CONCLUSION This report presents the first case series of patients with DADA2 from India, diagnosed by adult and pediatric care providers. The findings raise awareness of this syndrome, particularly with regard to its presentation in adults.

Abstract
As the multi-systemic components of COVID-19 emerge, parallel etiologies can be drawn between SARS-CoV-2 infection and radiation injuries. While some SARS-CoV-2-infected individuals present as asymptomatic, others exhibit mild symptoms that may include fever, cough, chills, and unusual symptoms like loss of taste and smell and reddening in the extremities (e.g., "COVID toes," suggestive of microvessel damage). Still others alarm healthcare providers with extreme and rapid onset of high-risk indicators of mortality that include acute respiratory distress syndrome (ARDS), multi-organ hypercoagulation, hypoxia and cardiovascular damage. Researchers are quickly refocusing their science to address this enigmatic virus that seems to unveil itself in new ways without discrimination. As investigators begin to identify early markers of disease, identification of common threads with other pathologies may provide some clues. Interestingly, years of research in the field of radiation biology documents the complex multiorgan nature of another disease state that occurs after exposure to high doses of radiation: the acute radiation syndrome (ARS). Inflammation is a key common player in COVID-19 and ARS, and drives the multi-system damage that dramatically alters biological homeostasis. Both conditions initiate a cytokine storm, with similar pro-inflammatory molecules increased and other anti-inflammatory molecules decreased. These changes manifest in a variety of ways, with a demonstrably higher health impact in patients having underlying medical conditions. The potentially dramatic human impact of ARS has guided the science that has identified many biomarkers of radiation exposure, established medical management strategies for ARS, and led to the development of medical countermeasures for use in the event of a radiation public health emergency. These efforts can now be leveraged to help elucidate mechanisms of action of COVID-19 injuries. Furthermore, this intersection between COVID-19 and ARS may point to approaches that could accelerate the discovery of treatments for both.

Abstract
While COVID-19 has primarily been characterized by the respiratory impact of viral pneumonia, it affects every organ system and carries a high consequent risk of death in critically ill patients. Higher sequential organ failure assessment (SOFA) scores have been associated with increased mortality in patients critically ill patients with COVID-19. It is important that clinicians managing critically ill COVID-19 patients be aware of the multisystem impact of the disease so that care can be focused on the prevention of end-organ injuries to potentially improve clinical outcomes. We review the multisystem complications of COVID-19 and associated treatment strategies to improve the care of critically ill COVID-19 patients.

Abstract
Erythropoiesis is a highly dynamic process giving rise to red blood cells from hematopoietic stem cells present in the bone marrow. Red blood cells transport oxygen to tissues thanks to the hemoglobin comprised of α- and β-globin chains and of iron-containing hemes. Erythropoiesis is the most iron-consuming process to support hemoglobin production. Iron delivery is mediated via transferrin internalization by the endocytosis of transferrin receptor type 1 (TFR1), one of the most abundant membrane proteins of erythroblasts. A second transferrin receptor—TFR2—associates with the erythropoietin receptor and has been implicated in the regulation of erythropoiesis. In erythroblasts, both transferrin receptors adopt peculiarities such as an erythroid-specific regulation of TFR1 and a trafficking pathway reliant on TFR2 for iron. This review reports both trafficking and signaling functions of these receptors and reassesses the debated role of TFR2 in erythropoiesis in the light of recent findings. Potential therapeutic uses targeting the transferrin-TFR1 axis or TFR2 in hematological disorders are also discussed.

Abstract
Red blood cell distribution width (RDW) is a measurement of the variation in size and volume of red blood cells (RBCs). Increased RDW, indicating a high heterogeneity of RBCs, is prominently associated with a variety of illnesses, especially cardiovascular diseases. However, the significance of this association to the onset and progression of cardiovascular and renal diseases is unknown. We hypothesized that a genetic predisposition for increased RDW is an early risk factor for cardiovascular and renal comorbidities. Since there is no known animal model of increased RDW, we examined a CRISPR/Cas9 gene-edited rat model (RfflTD) that presented with features of hematologic abnormalities as well as severe cardiac and renal comorbidities. A mass spectrometry-based quantitative proteomic analysis indicated anemia of these rats, which presented with significant downregulation of hemoglobin and haptoglobin. Decreased hemoglobin and increased RDW were further observed in RfflTD through complete blood count. Next, a systematic temporal assessment detected an early increased RDW in RfflTD, which was prior to the development of other comorbidities. The primary mutation of RfflTD is a 50 bp deletion in a non-coding region, and our study has serendipitously identified this locus as a novel quantitative trait locus (QTL) for RDW. To our knowledge, our study is the first to experimentally pinpoint a QTL for RDW and provides a novel genetic rat model mimicking the clinical association of increased RDW with poor cardio-renal outcome.

Abstract
Clonal hematopoiesis of indeterminate potential (CHIP) increases with age and is associated with increased risks of hematological malignancies. While TP53 mutations have been identified in CHIP, the molecular mechanisms by which mutant p53 promotes hematopoietic stem and progenitor cell (HSPC) expansion are largely unknown. Here we discover that mutant p53 confers a competitive advantage to HSPCs following transplantation and promotes HSPC expansion after radiation-induced stress. Mechanistically, mutant p53 interacts with EZH2 and enhances its association with the chromatin, thereby increasing the levels of H3K27me3 in genes regulating HSPC self-renewal and differentiation. Furthermore, genetic and pharmacological inhibition of EZH2 decreases the repopulating potential of p53 mutant HSPCs. Thus, we uncover an epigenetic mechanism by which mutant p53 drives clonal hematopoiesis. Our work will likely establish epigenetic regulator EZH2 as a novel therapeutic target for preventing CHIP progression and treating hematological malignancies with TP53 mutations.

Abstract
Kabuki syndrome is a rare genetic disorder, caused by mutation in the KMT2D or KDM6A genes, which affects several organs in the majority of patients, among which are the eyes. The most typical clinical characteristics are mental retardation, postnatal growth retardation, skeletal anomalies, and characteristic facial features. As the eyes are affected in most of the cases, ophthalmological examination is recommended for the early detection of ocular anomalies, in order to prevent visual impairment. The most frequent ocular signs are strabismus, ptosis, and refractive anomalies. A series of cases of Kabuki syndrome is described in five children, four of whom exhibited strabismus with esotropia, over action of inferior oblique muscles, and under action of superior oblique muscles associated with a V pattern. Most published papers do not report or might underestimate the ocular problems. It may be appropriate to perform orbital magnetic resonances in order to detect changes in the muscle paths that are related to the pathology of the eye movements found.

Abstract
Celiac disease (CD) is a systemic autoimmune disease driven by gluten-ingestion in genetically predisposed individuals. Although it primarily affects the small bowel, CD can also involve other organs and manifest as an extraintestinal disease. Among the extraintestinal features of CD, hematologic ones are rather frequent and consist of anemia, thrombocytosis (thrombocytopenia also, but rare), thrombotic or hemorrhagic events, IgA deficiency, hyposplenism, and lymphoma. These hematologic alterations can be the sole manifestation of the disease and should prompt for CD testing in a suggestive clinical scenario. Recognition of these atypical, extraintestinal presentations, including hematologic ones, could represent a great opportunity to increase the diagnostic rate of CD, which is currently one of the most underdiagnosed chronic digestive disorders worldwide. In this review, we summarize recent evidence regarding the hematological manifestations of CD, with focus on practical recommendations for clinicians.

Abstract
BACKGROUND Kabuki syndrome (KS) is a Mendelian disorder, characterised by short stature, facial dysmorphisms and developmental delay and/or intellectual disability. Clarification of the neurocognitive profile in KS may provide directions for education and treatment interventions for KS. Previous studies on cognitive functioning in KS are scarce and have mainly focused on the general level of intelligence. The few more extensive studies suggested weaknesses in language skills, visuoconstruction, perceptual reasoning and speed of information processing. Other relevant domains such as memory, executive functioning and social cognition have not been studied yet. METHOD This is the first study in which cognitive functioning within multiple domains is systematically explored in 29 participants with KS (age range: 5-48 years) and compared to both norm groups (healthy population) and an appropriate control group of 15 individuals with other genetic syndromes (age range: 6-28 years). RESULTS Compared to the norm groups of the cognitive test manuals, as expected, participants with KS show a weaker performance on all cognitive tests. Comparison with the more appropriate genetic control group indicates weaknesses in visuoconstruction and visual memory and no weaknesses in planning, cognitive flexibility or social cognition. Verbal memory seems to be a relative strength. CONCLUSIONS Individuals with KS suffer from specific weaknesses in visuoconstruction, in addition to their intellectual disability/developmental delay. These impairments in visuoconstruction plausibly result from problems in visual perceptual processing, which highlight the importance of the use of auditory cues instead of visual cues in targeted educational support and psychosocial interventions.

Abstract
BACKGROUND Kabuki (Niikawa-Kuroki) syndrome (KS) is caused by disease-causing variants in either of two components (KMT2D and KDM6A) of the histone methylation machinery. Nearly all individuals with KS have cognitive difficulties, and most have intellectual disability. Recent studies on a mouse model of KS suggest disruption of normal adult neurogenesis in the granule cell layer of the dentate gyrus of the hippocampus. These mutant mice also demonstrate hippocampal memory defects compared with littermates, but this phenotype is rescued postnatally with agents that target the epigenetic machinery. If these findings are relevant to humans with KS, we would expect significant and disproportionate disruption of visuospatial functioning in these individuals. METHODS To test this hypothesis, we have compiled a battery to robustly explore visuospatial function. We prospectively recruited 22 patients with molecularly confirmed KS and 22 IQ-matched patients with intellectual disability. RESULTS We observed significant deficiencies in visual motor, visual perception and visual motor memory in the KS group compared with the IQ-matched group on several measures. In contrast, language function appeared to be marginally better in the KS group compared with the IQ-matched group in a sentence comprehension task. CONCLUSIONS Together, our data suggest specific disruption of visuospatial function, likely linked to the dentate gyrus, in individuals with KS and provide the groundwork for a novel and specific outcome measure for a clinical trial in a KS population.

Abstract
Bone and marrow are the two facets of the same organ, in which bone and hematopoietic cells coexist and interact. Marrow and skeletal tissue influence each-other and a variety of genetic disorders directly targets both of them, which may result in combined hematopoietic failure and skeletal malformations. Other conditions primarily affect one organ with secondary influences on the other. For instance, various forms of congenital anemias reduce bone mass and induce osteoporosis, while osteoclast failure in osteopetrosis prevents marrow development reducing medullary cavities and causing anemia and pancytopenia. Understanding the pathophysiology of these conditions may facilitate diagnosis and management, although many disorders are presently incurable. This article describes several congenital bone diseases and their relationship to hematopoietic tissue.

Abstract
OBJECTIVE The purpose of the study is to determine the correlation of changes in the humoral and tissue components of the hemostasis system with lipid metabolism in case of various urgent surgical diseases, on the basis of which the systemic coagulopathic distress syndrome can be used as the scientific basis for the definition of a new syndrome. MATERIAL AND METHODS The work includes the results of experimental and clinical laboratory tests. Experiments on dogs: in the first group (n=18) destructive pancreatitis; in the second (n=18) - fecal peritonitis; in the third (n=15), acute obstructive intestinal obstruction; in the fourth (n=16) fecal peritonitis, in the postoperative period, Remaxol (15 ml/kg) was included in the therapy. The analysis of 55 patients with acute peritonitis, operated on for acute appendicitis, perforated gastric or duodenal ulcer, acute intestinal obstruction, acute destructive cholecystitis. In the study group (n=28), Remaxol is included in the postoperative therapy. The state of the humoral and tissue (in the experiment, the tissues of the liver, intestines, kidneys, heart, lungs, pancreas, in the clinic - tissues of the resected organs) components of the hemostasis system was evaluated, a number of lipid metabolism indicators were determined, etc. RESULTS In the early periods of all investigated urgent diseases of the abdomen, pronounced changes in the system of both humoral and tissue components of the hemostasis system were revealed. The modification of the coagulation system is registered not only in the tissues of the lesion organs, but also in the target organs (system tissue hemocoagulation modifications). The research established one of the most important processes - the trigger of the hemostatic cascade reaction - is membrane-destabilizing (the source of tissue thromboplastin), which is determined by changes in the phospholipid composition of various organs tissues (involved in the pathological process or not in it). Changes in lipid metabolism are due to the activation of phospholipases and membrane lipid peroxidation in tissues. The factual material was the scientific basis for the establishment of a new syndrome. Systemic coagulopathic distress syndrome is a set of pathological processes of the body, the most important component of which is a violation of the phospholipid bilayer of blood cell membranes and organ cells due to oxidative and phospholipase induced phenomena, leading to a coagulopathic condition. It changes understanding of the prevention of thrombohemorrhagic complications, proving the effectiveness of complex therapy, including not only anticoagulants, but also drugs with membrane-stabilizing activity, in particular, Remaxol.

Abstract
The purpose of our research was to determine the interrelation peculiarities of erythrocyte membrane deformability and cell diameter in a practically healthy person, in different age groups. 60 volunteers were selected for this survey in 5 age groups: 1) 17-25, 2) 25-35, 3) 35-60, 4) 60-75, 5) 75-90. As a result of the study, it was determined that with aging the diameter of peripheral blood erythrocytes increases and an indicator of deformability, in contrary, decreases. The average diameter of erythrocytes in young people, is directly correlated with erythrocyte deformability, while in elderly people, negative correlation is revealed between erythrocytes diameter and their deformability. Decrease in membrane deformability, demonstrated in peripheral blood erythrocytes of elderly people, indicates the participation of different mechanisms in erythrocyte membrane deformity regulation, it might be related to age-related metabolic changes.

Abstract
Balancing antitumor efficacy with toxicity is a significant challenge, and drug-induced myelosuppression is a common dose-limiting toxicity of cancer treatments. Mathematical modeling has proven to be a powerful ally in this field, scaling results from animal models to humans, and designing optimized treatment regimens. Here we outline existing mathematical approaches for studying bone marrow toxicity, identify gaps in current understanding, and make future recommendations to advance this vital field of safety research further.

Abstract
Kabuki syndrome (KS) is a rare disorder characterized by multiple congenital anomalies and variable intellectual disability caused by mutations in KMT2D/MLL2 and KDM6A/UTX, two interacting chromatin modifier responsible respectively for 56-75% and 5-8% of the cases. To date, three KS patients with mosaic KMT2D deletions in blood lymphocytes have been described. We report on three additional subjects displaying KMT2D gene mosaics including one in which a single nucleotide change results in a new frameshift mutation (p.L1199HfsX7), and two with already-known nonsense mutations (p.R4484X and p.R5021X). Consistent with previously published cases, mosaic KMT2D mutations may result in mild KS facial dysmorphisms and clinical and neurobehavioral features, suggesting that these characteristics could represent the handles for genetic testing of individuals with slight KS-like traits.

Abstract
The development of medical emergencies related to the underlying disease or as a result of complications of therapy are common in patients with hematologic or solid tumors. These oncological emergencies can occur as an initial presentation or in a patient with an established diagnosis and are encountered in all medical care settings, ranging from primary care to the emergency department and various subspecialty environments. Therefore, it is critically important that all physicians have a working knowledge of the potential oncological emergencies that may present in their practice and how to provide the most effective care without delay. This article reviews the most common oncological emergencies and provides practical guidance for initial management of these patients.

Abstract
Kabuki syndrome is a genetic condition characterized by distinctive facial phenotype, mental retardation, and internal organ malformations. Mutations of the epigenetic genes KMT2D and KDM6A cause dysregulation of certain developmental genes and account for the multiple congenital anomalies of the syndrome. Eight cases of malignancies have been reported in young patients with Kabuki syndrome although a causative association to the syndrome has not been established. We report a case of a 12-year-old girl with Kabuki syndrome who developed a tumor on the right side of her neck. A relapsing tumor 19 months after initial excision, proved to be giant cell fibroblastoma. Τhis is the first report of giant cell fibroblastoma -a rare tumor of childhood- in a patient with Kabuki syndrome.

Abstract
Calreticulin, encoded by CALR, is a multifunctional protein with roles in calcium homeostasis and chaperoning molecular processes. This study aimed to evaluate calreticulin mRNA expression levels in acute myeloid leukemia (AML) compared with other hematologic malignancies, and to investigate the clinicopathological characteristics associated with expression in AML patients. The study group included 43 patients diagnosed with AML, 57 with other hematologic malignancies, and 21 benign hematologic conditions. CALR mRNA quantification using real-time polymerase chain reaction revealed it to be significantly higher in AML compared with other hematologic malignancies (P < 0.0001). There was no difference in CALR mRNA expression between AML subgroups by karyotype (P = 0.3201). No differences were found in age, white blood cell counts, platelet counts, bone marrow blast percentage, calcium, lactate dehydrogenase or CD34 expression rate between the high and low CALR groups (CALR mRNA ≥ 1.2 fold and <1.2 fold, respectively), although hemoglobin and sex differences were observed. Although statistically not significant, there was a trend that Relapse rate was lower (54.5% vs. 84.6%) (P = 0.1063) and disease-free survival was longer (22 months vs. 7 months) (P = 0.0784) in low CALR group, whereas overall survival was similar between the two groups (11 months and 8 months). The clinical relevance of CALR expression in AML remains to be clarified in a larger cohort.

Abstract
Disorders of the blood system are a significant and growing global health concern and include a spectrum of diseases ranging from aplastic anemia and leukemias to immune suppression. This array of hematological disorders is attributed to the fact that the blood system undergoes a perpetual cycle of turn over with aged and exhausted red and white blood cells undergoing daily replacement. The foundational cells of this replenishment process are comprised of rare hematopoietic stem cells (HSCs) located in the bone marrow that possess the dual function of long-term self-renewal and multilineage differentiation. This constant turnover makes the hematopoietic system uniquely vulnerable to changes in the environment that impact multilineage differentiation, self-renewal, or both. Notably, environmental endocrine-disrupting exposures occurring during development, when HSCs are first emerging, can lead to alterations in HSC programming that impacts the blood and immune systems throughout life. In this review, we describe the process of fetal hematopoiesis and provide an overview of the intrauterine environmental and endocrine-disrupting compounds that disrupt this process. Finally, we describe research opportunities for fetal HSCs as potential sentinels of later-life blood and immune system disorders.

Abstract
Kabuki syndrome (KS) (Kabuki make-up syndrome, Niikawa-Kuroki syndrome) is a rare genetic disorder first diagnosed in 1981. Kabuki make-up syndrome (KMS) is a multiple malformation/intellectual disability syndrome that was first described in Japan but is now reported in many other ethnic groups. KMS is characterized by multiple congenital abnormalities: craniofacial, skeletal, and dermatoglyphic abnormalities; intellectual disability; and short stature. Other findings may include: congenital heart defects, genitourinary anomalies, cleft lip and/or palate, gastrointestinal anomalies including anal atresia, ptosis and strabismus, and widely spaced teeth and hypodontia. The KS is associated with mutations in the MLL2 gene in some cases were also observed deletions of KDM6A. This study describes three children with autism spectrum disorders (ASDs) and KS and rehabilitative intervention that must be implemented.

Abstract
OBJECTIVE To study the effectiveness of hemopoietic growth factors in older patients. DESIGN Literature review. All articles published in English language between 1987 and 1990 were reviewed. Those reporting studies without age limits as entry criteria and describing the effects of growth factors in individual patients were suitable for analysis. Bone marrow transplantation related articles were excluded. MAIN OUTCOME MEASURES The meanfold increase of granulocytes for Granulocyte-Colony Stimulating Factor, Granulocyte Macrophage-Colony Stimulating Factor, and Interleukin 3 and of hemoglobin for erythropoietin were compared in subjects younger and older than 65, by Mann-Whitney U test. RESULTS Of 68 studies, 23 were suitable for analysis. These included patients with myelodysplastic syndromes, aplastic anemia, chemotherapy-induced myelosuppression, chronic granulocytopenia, anemia, and myelosuppression of malignancies and of chronic disease. Of 204 patients, 67 were 65 years of age or older and 42 were over 70. No difference was seen in meanfold increase of granulocyte and hemoglobin in time of response to growth factors or in response in presence of an absolute neutrophil count lower than 1000/microliters between younger and older patients. CONCLUSION Early response to hemopoietic growth factors appears well maintained with advanced age. Prospective studies of the prolonged effects of these factors in older and younger patients are needed.

Abstract
PURPOSE OF THE STUDY To analyze complications of the pulmonary artery catheterization in patients with blood diseases. MATERIALS AND METHODS 93 cases of pulmonary artery catheterization in patients with blood diseases were included in the retrospective study. RESULTS Indications for pulmonary artery catheterization were septic shock (78.5%) and acute respiratory failure (21.5%). In 31 cases (33.3%) pulmonary artery catheterization was performed in conditions of agranulocytosis and in 81 cases (87%) in conditions of thrombocytopenia (platelets median 43 x 109 per liter minimal 7 x 109, maximal 150 x 109 per liter). Patients received transfusions of platelets in case of thrombocytopenia less than 30 x 109 per liter. Early complications of pulmonary artery catheterization occurred in 5 patients with thrombocytopenia (5.4%), the complications was connected with bleeding (hematoma, bleeding from place of puncture, lung bleeding) and mechanical (arterial puncture, pneumothorax, hemothorax). Number of attempts of the central vein catheterization was risk factor the complications. The frequency of catheter-associated sepsis was 5.89 cases each 1000 catheter-days and the frequency of infections of the soft tissues was 9.78 cases each 1000 catheter-days. Catheter-associated infection complications occurred in cases of catheter use over 5 days. Catheter-associated sepsis occurred in 2 of 3 patients with agranulocytosis. Other complications included intermittent arrhythmias during catheter moving in the heart chambers (58), catheter balloon rupture (4), and thrombosis of catheter lumen (3). CONCLUSIONS Pulmonary artery catheterization can be used in patients with blood diseases and first of all in cases of septic shock and acute respiratory failure. Alternative less invasive methods of monitoring should be used in patients with agranulocytosis.

Abstract
Red and white blood cells have two main functions: the carriage of oxygen; and defence against microbial attack. The full blood count is one of the most frequently requested routine blood tests; it provides key indices such as haemoglobin and the number of white cell subsets, and provides information to aid diagnosis of a range of conditions, including anaemia, infection, leukaemia, myeloma and lymphoma.

Abstract
OBJECTIVE To determine the frequency and types of renal malformations, and to evaluate renal function in a cohort of patients with Kabuki syndrome (KS). STUDY DESIGN Renal ultrasound scans and plasma creatinine measurements were collected from a French cohort of 94 patients with genotyped KS. Renal function was evaluated based on the estimated glomerular filtration rate. A genotype-phenotype study was conducted for renal and urinary tract malformations. RESULTS Renal malformations were present in 22% of cases, and urinary tract anomalies were present in 15%. Renal malformations were observed in 28% of the MLL2 mutation-positive group and in 0% of the MLL2 mutation-negative group (P = .015). No correlation was found between the presence or absence of renal or urinary tract malformations and the location or type of MLL2 mutation. Renal function was normal except for 1 patient with a MLL2 mutation diagnosed in the first days of life and severe renal disease due to unilateral renal agenesia and controlateral severe hypoplasia that progressed to the terminal stage at age 2 years. CONCLUSION Our study emphasizes the need for ultrasound and renal function screening in children diagnosed with KS.

Abstract
The understanding of pathological processes is based on the comparison between physiological and pathological conditions, and transcriptomic analysis has been extensively applied to various diseases for this purpose. However, the way in which the transcriptomic data of pathological cells relate to the transcriptomes of normal cellular counterparts has not been fully explored, and may provide new and unbiased insights into the mechanisms of these diseases. To achieve this, it is necessary to develop a method to simultaneously analyse components across different levels, namely genes, normal cells, and diseases. Here we propose a multidimensional method that visualises the cross-level relationships between these components at three different levels based on transcriptomic data of physiological and pathological processes, by adapting Canonical Correspondence Analysis, which was developed in ecology and sociology, to microarray data (CCA on Microarray data, CCAM). Using CCAM, we have analysed transcriptomes of haematological disorders and those of normal haematopoietic cell differentiation. First, by analysing leukaemia data, CCAM successfully visualised known relationships between leukaemia subtypes and cellular differentiation, and their characteristic genes, which confirmed the relevance of CCAM. Next, by analysing transcriptomes of myelodysplastic syndromes (MDS), we have shown that CCAM was effective in both generating and testing hypotheses. CCAM showed that among MDS patients, high-risk patients had transcriptomes that were more similar to those of both haematopoietic stem cells (HSC) and megakaryocyte-erythroid progenitors (MEP) than low-risk patients, and provided a prognostic model. Collectively, CCAM reveals hidden relationships between pathological and physiological processes and gene expression, providing meaningful clinical insights into haematological diseases, and these could not be revealed by other univariate and multivariate methods. Furthermore, CCAM was effective in identifying candidate genes that are correlated with cellular phenotypes of interest. We expect that CCAM will benefit a wide range of medical fields.

Abstract
The application of all-trans-retinoic acid (ATRA) in the protocols of treatment of acute promyelocyte leucosis provided the achievement of 95% of full remissions and fast correction of coagulopathy. Besides, ATRA along with positive impact can exert the side effects, among which the most dangerous is the differentiation syndrome. On the basis of analysis of clinical signs, biochemical, hemostasiologic and morphologic blood indicators it is established that among prognostic criteria of differentiation syndrome development are presence of febrile temperature, decrease of content of thrombocytes lesser than 20-109/l (deep degree of thrombocytopenia), prolongation of index of activated partial thromboplastin time relative to norm before treatment start. Apart from this, the following factors also are among such kind of criteria: decrease of hemoglobin after ATRA prescription before differentiation syndrome development, on-going hypofibrinogenemia and deep degree of thrombocytopenia under concurrent increase of content of urea and creatinine as compared with initial values in treatment dynamics.

Abstract
In utero hematopoietic cell transplantation (IUHCTx) is a promising strategy for the treatment of common hematopoietic disorders and for inducing immune tolerance in the fetus. Although the efficacy of IUHCTx has been demonstrated in multiple small and large animal models, the clinical application of this technique in humans has had limited success. Recent studies in mice have demonstrated that the maternal immune system plays a critical role in limiting engraftment in the fetus. This article reviews the therapeutic rationale of IUHCTx, potential barriers to its applications, and recent experimental strategies to improve its clinical success.

Abstract
OBJECTIVE To evaluate the magnetic resonance (MR) imaging and proton magnetic resonance spectroscopy ((1)H-MRS) in the diagnoses of pediatric hematological diseases. METHODS A total of 35 cases with pediatric hematological diseases were confirmed by bone marrow puncturing. There were acute leukemia (n = 26), aplastic anemia (n = 6), thalassemia (n = 2) and autoimmune hemolytic anemia (n = 1). Thirty age-marched healthy children underwent MR imaging (T(1)WI, T(2)WI, STIR) and (1)H-MRS of lumber spine and ilium. The lumber spines and iliums were studied by observation of MR imaging and calculation of fat fraction (FF%). RESULTS Two patterns were classified by MR imaging and (1)H-MRS in lumber spines and iliums of all cases. Pattern 1: hyperplasia of bone marrow (BM). There were acute leukemia (n = 26), thalassemia (n = 2) and autoimmune hemolytic anemia (n = 1). The manifestations included homogeneous low signal intensity (SI) on T(1)WI, homogeneous low SI on T(2)WI, high SI on STIR and high water peak and low fat peak on (1)H-MRS. The FF%s of Regions of Interest (ROI) in lumber 4s and left iliums of 26 cases with acute leukemia were 0%, of 3 cases with thalassemia or autoimmune hemolytic anemia were 5.02% and 3.70%. Pattern 2: inhibition of BM. There were 6 cases of aplastic anemia. The manifestations included homogeneous or inhomogeneous high SI on T(1)WI and T(2)WI, homogeneous or inhomogeneous low SI on STIR, and low water peak and high fat peak on (1)H-MRS. FF%s of ROI in lumber 4s and left iliums for 6 cases of aplastic anemia were 74.69% and 91.51%. FF% in all groups had significant differences according to the Mann-Whitney test (P < 0.05). CONCLUSIONS MR imaging and (1)H-MRS may serve as a noninvasive method for checking hematopoietic status of bone marrow in pediatric hematological diseases.

Abstract
From June 10th -14th, 2011, Yaroslavl played host to the traditional VIII International Conference <Systemic Circulation, Microcirculation and Haemorheology,> (from angiogenesis to central circulation) with a school for young scientists. The reports discussed cellular and molecular mechanisms of changes in the microrheological properties of RBCs and WBCs. as well as a role of a series of signal compounds and their receptors in regulation of angiogenesis.Also presented were the results of using new methods of investigations such as atomic-power microscopy, computer-assisted video-biomicroscopy of vessels of bulbar conjunctiva, bioimpedance spectroscopy.Some works examined the effect of drugs and certain chemical compounds on microrheological properties of RBCs, as well as peculiarities of haemorheological indices in certain conditions:obesity, ischaemic heart disease on the background of arterial hypertension, myocardial infarction, in nephrological patients, in various types of stress, systemic lupus erythematosus, sickle-cell anaemia, chronic obstructive pulmonary disease.Some works were dedicated to acute impairments of cerebral circulation both in experimental and clinical conditions.A large aspect of the Conference's work touched upon physiological and pathophysiological mechanisms of alterations in the systemic circulation and microcirculation. A separate division of the Program was called ,Haemostasis, thromboses and haemorheology: points of interactions. There was also a master-class: ,Study of molecular signalling pathways of erythrocytes associated with alteration in their microrheologicalproperties

Abstract
PURPOSE to evaluate the hypothesis that the fetal cerebroplacental ratio (CPR) is related to acidemia at birth in pregnancies complicated by placental insufficiency detected before 34 weeks of gestation. METHODS this is a prospective cohort study of 55 patients between 26 and 34 weeks of gestation with a diagnosis of placental insufficiency characterized by abnormal umbilical artery Doppler (pulsatility index>95 p). Fetal assessment was performed for each patient by dopplervelocimetry of the umbilical artery, middle cerebral artery and ductus venosus, and by the fetal biophysical profile. CPR was calculated using the ratio between middle cerebral artery pulsatility index and umbilical artery pulsatility index, and the z-score was obtained (number of standard deviations of the mean value at each gestational age). Acidemia at birth was characterized when pH<7.2. RESULTS of 55 patients, 29 (52.7%) presented acidemia at birth. In the group of fetal acidemia, when compared with the group with pH>7.2, a significant association was observed with CPR values (median 0.47 versus 0.58; p=0.009), pulsatility index of the umbilical artery (median 2.45 versus 1.93; p=0.003), ductus venosus pulsatility index for veins (PIV) (median 1.08 versus 0.85; p=0.034) and suspected or abnormal fetal biophysical profile (37 versus 8%; p=0.031). CPR analysis by z-score showed a negative tendency, but was not statistically significant (p=0.080). Significant correlations were found between pH at birth and CPR (r=0.45; p<0.01), z-score of CPR (r=0.27; p<0.05) and ductus venosus PIV (r=-0.35 p<0.01). CONCLUSION CPR is associated with the presence of acidemia at birth in pregnancies with placental insufficiency detected before 34 weeks of gestation and this parameter could potentially represent a factor for assessing the severity of fetal involvement.

Abstract
Several populations of adult human stem cells have been identified, but only a few of these are in routine clinical use. The hematopoietic stem cell (HSC) is arguably the most well characterized and the most routinely transplanted adult stem cell. Although details regarding several aspects of this cell's phenotype are not well understood, transplant of HSCs has advanced to become the standard of care for the treatment of a range of monogenic diseases and several types of cancer. It has also proven to be an excellent target for genetic manipulation, and clinical trials have already demonstrated the usefulness of targeting this cell as a means of delivering nucleic acid therapeutics for the treatment of several previously incurable diseases. It is anticipated that additional clinical trials will soon follow, such as genetically engineering HSCs with vectors to treat monogenic diseases such as hemophilia A. In addition to the direct targeting of HSCs, induced pluripotent stem (iPS) cells have the potential to replace virtually any engineered stem cell therapeutic, including HSCs. We now know that for the broad use of genetically modified HSCs for the treatment of non-lethal diseases, e.g. hemophilia A, we must be able to regulate the introduction of nucleic acid sequences into these target cells. We can begin to refine transduction protocols to provide safer approaches to genetically manipulate HSCs and strategies are being developed to improve the overall safety of gene transfer. This review focuses on recent advances in the systemic delivery of nucleic acid therapeutics using genetically modified stem cells, specifically focusing on i) the use of retroviral vectors to genetically modify HSCs, ii) the expression of fVIII from hematopoietic stem cells for the treatment of hemophilia A, and iii) the use of genetically engineered hematopoietic cells generated from iPS cells as treatment for disorders of hematopoiesis.

Abstract
Considerable interest for cell-derived microparticles has emerged, pointing out their essential role in haemostatic response and their potential as disease markers, but also their implication in a wide range of physiological and pathological processes. They derive from different cell types including platelets - the main source of microparticles - but also from red blood cells, leukocytes and endothelial cells, and they circulate in blood. Despite difficulties encountered in analyzing them and disparities of results obtained with a wide range of methods, microparticle generation processes are now better understood. However, a generally admitted definition of microparticles is currently lacking. For all these reasons we decided to review the literature regarding microparticles in their widest definition, including ectosomes and exosomes, and to focus mainly on their role in haemostasis and vascular medicine.

Abstract
Haematopoietic growth factors constitute an important group of proteins that predominantly regulate the process of haematopoiesis. While some of these proteins have a very broad array of action on very early haematopoietic progenitors leading to multi-lineage increases in haematopoietic cell production and differentiation, others act in a restricted manner on specific committed terminally differentiated cell types. On the basis of their unique spectrum of activities, several factors are approved for clinical use in various indications while others are under investigation in the clinic either alone or as combination therapy. In this review, we have described factors which directly and in some cases indirectly influence haematopoiesis with particular focus on those factors which are either approved or show potential for clinical use. A brief description of the products that are currently available for clinical use is also provided. At present, several new products which include fusion proteins, peptide mimetics are either at the pre-clinical stage or in clinical development for various indications and these are also briefly described.

Abstract
The term blueberry muffin baby was initially coined by pediatricians to describe cutaneous manifestations observed in newborns infected with rubella during the American epidemic of the 1960s. These children had generalized hemorrhagic purpuric eruptions that on histopathology showed dermal erythropoiesis. Since then, congenital infections comprising the TORCH syndrome (toxoplasmosis, other, rubella, cytomegalovirus, herpes) and hematologic dyscrasias have classically been associated with blueberry muffin-like lesion.

Abstract
This article summarizes the progress of hematology in the recent tens years to show that experimental hematology used to pick up the 'hints' from clinical problems as the renewal of research directions and targets in experimental studies continuously. As the feedback, the results from lab investigations inserted into clinical practice and eventually made a quick modernization of hematology, which was actually a good model for the "translational research". The past few decades have witnessed tremendous advances in our understanding of normal hematopoiesis where genes dictate, epigenetics regulate, transcription factors mediate, and stem cells self-renew and differentiate. Dissection of disease pathogenesis not only elucidates molecular basis of disorders including hemoglobinopathy, aplastic anemia, hemophilia, hematopoietic malignancies such as leukemia and myeloproliferative disorders, but also provides therapeutic targets for drug development. Introduction of targeted therapies and combinatory targeting therapies greatly benefits hundreds of thousands of patients, and even turns acute promyelocytic leukemia from highly fatal to highly curable. In the 21st century the experimental hematology is entering the era of genomics and system biomedicine, and the pace of progress extrapolates to a prediction of hematologic neoplasms control in this century.
