    This is the sixth special report that the European Society for Blood and Marrow Transplantation regularly publishes on the current practice and indications for haematopoietic SCT for haematological diseases, solid tumours and immune disorders in Europe. Major changes have occurred in the field of haematopoietic SCT over the last years. Cord blood units as well as haploidentical donors have been increasingly used as stem cell sources for allo-SCT, thus, augmenting the possibility of finding a suitable donor for a patient. Continuous refinement of conditioning strategies has also expanded not only the number of potential indications but also has permitted consideration of older patients or those with co-morbidity for a transplant. There is accumulating evidence of the role of haematopoietic SCT in non-haematological disorders such as autoimmune diseases. On the other hand, the advent of new drugs and very effective targeted therapy has challenged the role of SCT in some instances or at least, modified its position in the treatment armamentarium of a given patient. An updated report with revised tables and operating definitions is presented.

    Gaucher disease (GD) is an autosomal recessive lysosomal storage disease, caused by deficiency of the enzyme glucocerebrosidase, required for the degradation of glycosphingolipids. Clinical manifestations include hepatosplenomegaly, thrombocytopenia, bone disease and a bleeding diathesis, frequently resulting in presentation to haematologists. Historically managed by splenectomy, transfusions and orthopaedic surgery, the development of specific therapy in the form of intravenous enzyme replacement therapy in the 1990s has resulted in dramatic improvements in haematological and visceral disease. Recognition of complications, including multiple myeloma and Parkinson disease, has challenged the traditional macrophage-centric view of the pathophysiology of this disorder. The pathways by which enzyme deficiency results in the clinical manifestations of this disorder are poorly understood; altered inflammatory cytokine profiles, bioactive sphingolipid derivatives and alterations in the bone marrow microenvironment have been implicated. Further elucidating these pathways will serve to advance our understanding not only of GD, but of associated disorders. © 2014 John Wiley & Sons Ltd.

    Full Text Available BACKGROUND Liver plays an important role in normal erythropoiesis and synthesis of clotting factors. Chronic liver disease (CLD patients are frequently associated with abnormalities in haematological parameters. MATERIALS AND METHODS This was an observational study conducted among diagnosed CLD patients over a period of 1 year from 2013 to 2014. Various haematological abnormalities in 75 CLD patients were studied. Relevant details were obtained in structured format. RESULTS The mean age of the study group 49.2 years. Male-to-female ratio was 5.8:1. Aetiologies of cirrhosis were alcoholism (61.3%, diabetes mellitus (26.7% and dyslipidaemia (13%. 88% patients were anaemic with severe anaemia (Hb <8 gm% observed in 33.3% patients with mean Hb being 8.76 gm%. Mean Hb in alcohol-related CLDs were lower than CLDs due to other aetiologies (8.62 gm% vs. 9.36 gm%. Most common anaemia observed was normocytic normochromic anaemia (40.9%. 26.7% had leucopenia and 88% had thrombocytopenia. Normal ferritin levels were observed in 6.7%, decreased in 16% and increased in the remaining cases of which a level of more than 900 ng/mL was observed in 18.7% cases. Mean CTP (ChildTurcotte-Pugh score of the study group was 11.1. 80% of patients belong to child C. Patients with high ferritin levels had high CTP score (P-0.001. Platelet count decreases as CTP score increases (P-0.000 and as spleen size increases (P-0.001. CONCLUSION Most common haematological abnormalities observed were thrombocytopenia and anaemia. Severe anaemia was seen in males and alcoholics. Thrombocytopenia was more in those with advanced liver disease and large spleen. High serum ferritin level correlate well with advanced liver disease.

    Full Text Available The course and outcome of a disease process is dependent upon factors such as the disease-causing agent and its cell tropism, defense mechanisms of the host, genetic resistance of the species or breed affected, as well as the age, nutritional status and hormonal levels of the affected animal. When haematology, clinical biochemistry and cytology test results are combined with other laboratory procedures, complete physical examination and also with the history of the patient, a veterinarian is well armed to arrive at a definitive diagnosis, make a certain prognosis (good, poor or guarded and can also make a concluding statement on the efficacy of the instituted therapy. In clinical biochemistry, demonstration of specific enzyme activity and concentration of analytes in serum/plasma facilitates the disease diagnosis. Also, evaluation of haematology, clinical biochemistry and diagnostic cytology tests can help establish the presence or absence of diseases of internal organs, and by serial performance of these tests, may help to determine whether a disease process remains static, progressive or regressive. This review therefore provides the haematological, serum biochemical and cytological characteristics of diseases caused by the main bacteria, viruses, fungi, protozoa, helminths, arthropods, nutritional deficiencies, endocrine disturbances, neoplasm, allergy, toxins (phytoxins and zootoxins and inorganic poisons in horses.

    Full Text Available BACKGROUND Chronic kidney disease (CKD is a major public health problem causing significant morbidity and mortality worldwide. Diabetes mellitus (DM and hypertension are common causes and anaemia is a common complication. It is important to identify the cause and complication, to treat it and prevent its progression to end-stage renal disease (ESRD. AIM To identify the haematological pattern in chronic kidney disease patients and to study the clinical presentation. MATERIALS AND METHODS 72 cases of CKD were studied for a period of 6 months and thorough assessment of clinical features and haematological examinations were done. RESULTS CKD is observed in all age groups and predominantly in older age group greater than 50 yrs., with male preponderance. DM and hypertension are common causes. 89% of the patients presented with anaemia and 4 cases of sickle cell anaemia were observed. Neutrophilic leucocytosis was seen in 29.2% and thrombocytopenia in 8.3% of cases. CONCLUSION CKD is seen in all age groups with a male predominance, common in older age group, anaemia being the most common and important haematological complication. Few cases of sickle cell anaemia (SCA were seen presenting with CKD. Knowledge and treatment of these conditions has proved to improve the quality of life.

    Epstein-Barr virus (EBV), a ubiquitous human herpesvirus, maintains lifelong subclinical persistent infections in humans. In the circulation, EBV primarily infects the B cells, and protective immunity is mediated by EBV-specific cytotoxic T cells (CTLs) and natural killer (NK) cells. However, EBV has been linked to several devastating diseases, such as haemophagocytic lymphohistiocytosis (HLH) and lymphoproliferative diseases in the immunocompromised host. Some types of primary immunodeficiencies (PIDs) are characterized by the development of EBV-associated complications as their predominant clinical feature. The study of such genetic diseases presents an ideal opportunity for a better understanding of the biology of the immune responses against EBV. Here, we summarize the range of PIDs that are predisposed to EBV-associated haematological diseases, describing their clinical picture and pathogenetic mechanisms. © 2013 John Wiley & Sons Ltd.

    1992-01-01

    Nuclear techniques have been applied to study diagnose and treat various haematological disorders for more than five decades. Two scientists are regarded as pioneers in this field, i.e. John Lawrence who in 1938 used 32 P to treat chronic myeloid leukaemia and George Hevessy who used 32 P labelled erythrocytes to measure blood volume in 1939. At present, many nuclear medicine procedures are available for diagnosis and therapy of a variety of haematological disorders. Although nuclear techniques are somewhat complex, they give direct and quantitative assessment of the kinetics of blood elements as compared to other non-isotopic haematological tests. Basically, equipment required for nuclear haematology is very simple such as well scintillation counters to measure radioactivity in blood samples. More sophisticated equipment like rectilinear scanner or gamma camera is required when imaging is necessary. An overview of the basic principles and clinical applications of nuclear haematology is given

    To report the outcomes associated with the use of rabbit anti-dog thymocyte serum in dogs with haematological immune-mediated diseases. Medical records from 2000 to 2016 of patients diagnosed with immune-mediated haemolytic anaemia, immune-mediated thrombocytopenia, pancytopenia and myelofibrosis were reviewed. All dogs had a severe or refractory disease and received rabbit anti-dog thymocyte serum. Lymphocyte counts were used to monitor the immediate anti-thymocyte effect of therapy; long-term patient outcome was recorded. A total of 10 dogs were included. All dogs except one had a notable decrease in their lymphocyte count after rabbit anti-dog thymocyte serum; four of nine had a decrease to less than 10% of the initial lymphocyte count and one dog reached 10·8%. All dogs were discharged from the hospital following their treatment. The dog with no alteration of lymphocyte count following therapy with rabbit anti-dog thymocyte serum had refractory immune mediated haemolytic anemia and was euthanised within two weeks. All other cases achieved clinical remission with immunosuppressive therapy eventually being tapered (3 of 10) or discontinued (6 of 10). Rabbit anti-dog thymocyte serum therapy might be of interest as an adjunctive therapy in refractory immune-mediated diseases and suppressed lymphocyte counts in most dogs. © 2017 British Small Animal Veterinary Association.

  1. The 'royal disease'--haemophilia A or B? A haematological mystery is finally solved.

    Science.gov (United States)

    Lannoy, N; Hermans, C

    2010-11-01

      'History can change blood. And blood can change the course of history'. Haemophilia is an illustration of this, as this congenital hereditary coagulation disorder, passed through the majority of royal European families at the beginning of the 20th century by Queen Victoria of England and Empress of the Indies, had indisputable political consequences, which led to one of the most defining moments of contemporary history: the Bolshevik Revolution. Today, none of Queen Victoria's living descendents carry haemophilia. Because of this, the characterization of haemophilia (deficit of either factor VIII or XI) and the identification of the causal mutation are rendered impossible. In 1991, a tomb containing the remains of Czar Nicolas II's entire family was discovered. A second tomb was discovered in 2007, allowing Russian and American scientists to fill in this gap in medical history. Following a scientific approach combining current genetic experimentation tools and the development of biological information technology, researchers were able to identify each body, allowing them to obtain precious genetic material from the young Czar Alexis, who was stricken by the disease, which revealed a causal substitution in the splice acceptor site of exon 4 in the F9 gene. This mutation that is responsible for haemophilia B had traumatized European royal families throughout the 20th century! © 2010 Blackwell Publishing Ltd.

    This paper describes the transmission of hepatitis A virus (HAV) to two blood recipients from a healthy donor that later presented to the blood bank with jaundice. The RNA of HAV was detected by qualitative nested reverse transcription polymerase chain reaction (nested RT-PCR) and quantified by real-time RT-PCR. HAV RNA samples were genotyped by direct sequencing of PCR products. A sequence from a fragment of 168 bp from the VP1/2A HAV region was used to construct a phylogenetic tree. A 31-year-old male donor accepted for donation of a whole blood unit returned to the blood bank with clinical jaundice 20 days after donation. His serological and NAT tests were negative for HBV and HCV. Serological tests for HAV IgM and IgG were negative on donation sample but positive on follow-up sample, confirming donor's HAV acute infection. Both recipients of red blood cells (R1) and platelet concentrate (R2) from the same implicated donation were HAV IgM-negative and IgG-positive. Qualitative PCR was positive on samples from all three individuals and phylogenetic analysis of viruses proved HAV transmission to the two recipients of blood products. HAV viral load on donor follow-up sample and the platelet recipient was 1.3 and 1.5 × 10(3) IU/ml, respectively. The RBC recipient, also infected by HCV, was undergoing bone marrow transplantation and died from fulminant hepatitis, 26 days after the implicated HAV transfusion. The blood donor, a garbage collector, spontaneously returned to the blood bank when developing jaundice. This highlights the importance of donor education to immediately report to blood banks of any signs and symptoms related to infectious disease developed after blood donation. The fact that one immunocompromised patient with HCV infection died from fulminant hepatitis after receiving a HAV-contaminated platelet transfusion underpins the importance of a HAV vaccination program for these group of patients.

  3. Haematological emergencies managing hypercalcaemia in adults and children with haematological disorders.

    LENUS (Irish Health Repository)

    Sargent, Jeremy T S

    2012-02-01

    Hypercalcaemia is a common metabolic complication of malignant disease often requiring emergency intervention. Although it is more frequently associated with solid tumours, malignancy-associated hypercalcaemia (MAH) is seen in a significant number of patients with blood diseases. Its association with myeloma and adult T-cell leukaemia\\/lymphoma is well recognized but the incidence of hypercalcaemia in other haematological neoplasms, affecting adults and children, is less clearly defined. Haematologists need to be familiar with the clinical manifestations of, the differential diagnosis to be considered and the most effective management strategies that are currently available for MAH. The key components of management of MAH include aggressive rehydration, specific therapy to inhibit bone resorption and, crucially, treatment of the underlying malignancy. Bisphosphonates have revolutionized the management of MAH over the last 20 years, however the elucidation of molecular pathways implicated in MAH is facilitating the development of more targeted approaches to treatment.

    2015-01-01

    Our purpose was to compile information on the haematological manifestations of systemic lupus erythematosus (SLE), namely leucopenia, lymphopenia, thrombocytopenia, autoimmune haemolytic anaemia (AIHA), thrombotic thrombocytopenic purpura (TTP) and myelofibrosis. During our search of the English-language MEDLINE sources, we did not place a date-of-publication constraint. Hence, we have reviewed previous as well as most recent studies with the subject heading SLE in combination with each manifestation. Neutropenia can lead to morbidity and mortality from increased susceptibility to infection. Severe neutropenia can be successfully treated with granulocyte colony-stimulating factor. While related to disease activity, there is no specific therapy for lymphopenia. Severe lymphopenia may require the use of prophylactic therapy to prevent select opportunistic infections. Isolated idiopathic thrombocytopenic purpura maybe the first manifestation of SLE by months or even years. Some manifestations of lupus occur more frequently in association with low platelet count in these patients, for example, neuropsychiatric manifestation, haemolytic anaemia, the antiphospholipid syndrome and renal disease. Thrombocytopenia can be regarded as an important prognostic indicator of survival in patients with SLE. Medical, surgical and biological treatment modalities are reviewed for this manifestation. First-line therapy remains glucocorticoids. Through our review, we conclude glucocorticoids do produce a response in majority of patients initially, but sustained response to therapy is unlikely. Glucocorticoids are used as first-line therapy in patients with SLE with AIHA, but there is no conclusive evidence to guide second-line therapy. Rituximab is promising in refractory and non-responding AIHA. TTP is not recognised as a criteria for classification of SLE, but there is a considerable overlap between the presenting features of TTP and SLE, and a few patients with SLE have concurrent

    Patients with relapsed or refractory malignancies have a poor prognosis. Immunotherapy with chimeric antigen receptor T (CAR-T) cells redirects a patient's immune cells against the tumour antigen. CAR-T cell therapy has demonstrated promise in treating patients with several haematological malignancies, including acute B-cell lymphoblastic leukaemia and B-cell lymphomas. CAR-T cell therapy for patients with other solid tumours is also being tested. Safety is an important consideration in CAR-T cell therapy given the potential for serious adverse events, including death. Previous reviews on CAR-T cell therapy have been limited in scope and methodology. Herein, we present a protocol for a systematic review to identify CAR-T cell interventional studies and examine the safety and efficacy of this therapy in patients with haematology malignancies and solid tumours. We will search MEDLINE, including In-Process and Epub Ahead of Print, EMBASE and the Cochrane Central Register of Controlled Trials from 1946 to 22 February 2017. Studies will be screened by title, abstract and full text independently and in duplicate. Studies that report administering CAR-T cells of any chimeric antigen receptor construct targeting antigens in patients with haematological malignancies and solid tumours will be eligible for inclusion. Outcomes to be extracted will include complete response rate (primary outcome), overall response rate, overall survival, relapse and adverse events. A meta-analysis will be performed to synthesise the prevalence of outcomes reported as proportions with 95% CIs. The potential for bias within included studies will be assessed using a modified Institute of Health Economics tool. Heterogeneity of effect sizes will be determined using the Cochrane I 2 statistic. The review findings will be submitted for peer-reviewed journal publication and presented at relevant conferences and scientific meetings to promote knowledge transfer.

  9. Bone marrow solid core biopsy needle: a critical assessment of the utility, benefits and limitations of the instruments employed in current day haematology and oncology.

    2018-06-01

    The optimal clinical evaluation of the bone marrow requires an examination of air-dried and well-stained films of the aspirated tissue along with a histopathological evaluation of adequately processed and properly stained core biopsy specimens. A bone marrow evaluation can be essential in establishing a diagnosis, determining the efficacy of treatment in haematological disorders and to monitor haematological status of patients following bone marrow/stem cell transplantation. It is also an essential component of the staging process for newly diagnosed malignancies. Currently available bone marrow aspiration needles are quite satisfactory and if properly used provide good-quality specimens for morphological evaluation. However, if a bone marrow core biopsy is concerned, several needles are currently in use but not all of them provide good-quality biopsy specimens for histological evaluation or are user friendly. We have compared the recently introduced Moeller Medical single use bone marrow core biopsy needle with the Jamshidi needle with marrow acquisition cradle (CareFusion), J-needle (Cardinal Health) and OnControl device (Vidacare). It is concluded that the Moeller Medical needle system has definite advantages over others and is recommended for routine use. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Full Text Available The incidence of cancer in human is high as compared to chimpanzee. However previous analysis has documented that numerous human cancer-related genes are highly conserved in chimpanzee. Till date whether human genome includes species-specific cancer-related genes that could potentially contribute to a higher cancer susceptibility remains obscure. This study focuses on MYEOV, an oncogene encoding for two protein isoforms, reported as causally involved in promoting cancer cell proliferation and metastasis in both haematological malignancies and solid tumours. First we document, via stringent in silico analysis, that MYEOV arose de novo in Catarrhini. We show that MYEOV short-isoform start codon was evolutionarily acquired after Catarrhini/Platyrrhini divergence. Throughout the course of Catarrhini evolution MYEOV acquired a gradually elongated translatable open reading frame (ORF, a gradually shortened translation-regulatory upstream ORF, and alternatively spliced mRNA variants. A point mutation introduced in human allowed for the acquisition of MYEOV long-isoform start codon. Second, we demonstrate the precious impact of exonized transposable elements on the creation of MYEOV gene structure. Third, we highlight that the initial part of MYEOV long-isoform coding DNA sequence was under positive selection pressure during Catarrhini evolution. MYEOV represents a Primate Orphan Gene that acquired, via ORF expansion, a human-protein-specific coding potential.

    Full Text Available Following their immunisation and infection with a VSHI-CN-6 viral strain, a group of 15 rabbits were examined in a study of Rabbit Haemorrhagic Disease (RHD. Serum samples were collected from the external ear vein at 0, 15, 30 and 60 days post-immunisation. The recorded platelet numbers were closer to the lower physiological limit, indicating a mild thrombocytopenia, with values ranging from 26.6 to 30.43×104/mm3. The phagocytic index revealed significant differences (P<0.001 between the mean values obtained before vaccination (day 0 and the 3 post-vaccination measurements, confirming the increase in phagocytic capacity after immunisation. Additionally, the serum lysozyme average value equalled 9.14 mg/mL post-vaccination. The analysis of variance revealed significant statistical differences (P<0.05 between the average values obtained before vaccination (0 and the post-vaccination values, measured on day 14 and 30, respectively. The morphology of the samples collected from the main organs involved in immune protection, spleen and gastric and portal lymph nodes highlighted changes corresponding to the post-vaccination immunological response. The white pulp of the spleen appeared as a diffuse lymphoid tissue, presenting with primary and secondary lymphoid follicles. The ratio of white/red pulp was in favour of the white pulp and multiple lymphoid follicles were present, indicating their reactivation. In the medullary area of gastric and portal lymph nodes, narrow lymphoid cords, circumscribed by relatively large lymphatic sinuses, and well defined lymphocytolysis were observed. Moreover, the exudate and lymphoid follicles during activation were noted in the cortical area. Furthermore, the inflammatory processes were identified, morphologically manifested by the thickening of connective tissue in the lymph node capsule, dilacerations of the connective fibres and the presence of light acidophilic serous exudate with rare inflammatory cells (serous

    2011-03-01

    Full Text Available Zygomycoses are rare emerging diseases with a high fatality rate.  The most important risk factors include neutropenia or functional neutropenia, diabetic ketoacidosis, iron overload, major trauma, prolonged use of corticosteroids, illicit intravenous drug use, neonatal prematurity, malnourishment, and pre-exposure to antifungal agents with no activity against zygomycetes, such as voriconazole and caspofungin. A high index of suspicion is crucial for the diagnosis, as prompt and appropriate management can considerably reduce morbidity and mortality. Suspicion index can be increased through recognition of the differential patterns of clinical presentation. In the non- haematological immunocompromised patients, zygomycosis can manifest in various clinical forms, depending on the underlying condition: mostly as rhino-orbital or rhino-cerebral in diabetes patients, pulmonary infection in patients with malignancy or solid organ transplantation, disseminated infection in iron overloaded or deferoxamine treated patients, cerebral - with no sinus involvement - in ID users, gastrointestinal in premature infants or malnourishment, and cutaneous after direct inoculation in immunocompetent individuals with trauma or burns. Treating a patient’s underlying medical condition and reducing immunosuppression are essential to therapy. Rapid correction of metabolic abnormalities is mandatory in cases such as uncontrolled diabetes and corticosteroids or other immunosuppressive drugs should be discontinued where feasible. AmphotericinB or its newer and less toxic lipid formulations are the drugs of choice regarding antifungal chemotherapy, while extensive surgical debridemend is essential to reduce infected and necrotic tissue. A high number of cases could be prevented through measures including diabetes control programmes and proper pre- and post-surgical hygiene.

  18. Meditation for adults with haematological malignancies.

    2016-02-03

    Malignant neoplasms of the lymphoid or myeloid cell lines including lymphoma, leukaemia and myeloma are referred to as haematological malignancies. Complementary and alternative treatment options such as meditation practice or yoga are becoming popular by treating all aspects of the disease including physical and psychological symptoms. However, there is still unclear evidence about meditation's effectiveness, and how its practice affects the lives of haematologically-diseased patients. This review aims to assess the benefits and harms of meditation practice as an additional treatment to standard care for adults with haematological malignancies. We searched the Cochrane Central Register of Controlled Trials (CENTRAL, Issue 8, 2015), MEDLINE (1950 to August 2015), databases of ongoing trials, the metaRegister of Controlled Trials (mRCT) (http://www.controlled-trials.com/mrct/), conference proceedings of annual meetings of: the American Society of Hematology; American Society of Clinical Oncology; European Hematology Association; European Congress for Integrative Medicine; and Global Advances in Health and Medicine (2010 to 2015). We included randomised controlled trials (RCTs) using meditation practice for adult patients with haematological malignancies. Two review authors independently extracted data from eligible studies and assessed the risk of bias according to predefined criteria. We evaluated quality of life and depression. The other outcomes of overall survival, anxiety, fatigue, quality of sleep and adverse events could not be evaluated, because they were not assessed in the included trial. We included only one small trial published as an abstract article. The included study investigated the effects of meditation practice on patients newly hospitalised with acute leukaemia. Ninety-one participants enrolled in the study, but only 42 participants remained in the trial throughout the six-month follow-up period and were eligible for analysis. There was no

  19. Manual on radiation haematology

    International Nuclear Information System (INIS)

    1971-01-01

    Studies of the biological effects of ionizing radiation have led to the introduction of various measures to protect both the public and personnel engaged in occupations where they could be exposed to such radiations. Many recent studies deal with the basic mechanism of radiation injuries and with their treatment, and some of these investigations have been sponsored by the World Health Organization and the International Atomic Energy Agency. Fundamental studies of the blood-forming tissue have provided the information necessary for formulating recommendations of the International Commission on Radiological Protection. Heinecke in 1903 was the first to note damage to the haemato-poietic tissue after whole-body irradiation. Since that time we have learned much of the functions of the various components of the blood. Many studies have been undertaken to understand the proliferative capacities of the various 'stem' cells involved in the haematopoietic processes and the extent to which these processes can be interfered with by ionizing radiations. We now understand which are the reliable criteria by which radiation damage can be assessed from its effects on the haematopoietic system. In addition, much work has been done to determine how radiation injury to the hematopoietic system may be offset by therapy. In developing countries radiation is being increasingly applied in medical work and many other fields, and there is an immediate need to disseminate information relevant to radiation hazards. This Manual on Radiation Haematology is an attempt at a synthesis of much that is relevant to these matters. As the Contents List shows, many experts have contributed to the book. Their styles have been changed as little as possible. A certain amount of duplication of information could not be avoided; where an editorial decision to remove a passage would have resulted in losing the exact concept that the author wished to express, this passage has been retained.

    Alloimmune inflammation damages the microvasculature of solid organ transplants during acute rejection. Although immunosuppressive drugs diminish the inflammatory response, they do not directly promote vascular repair. Repetitive microvascular injury with insufficient regeneration results in prolonged tissue hypoxia and fibrotic remodeling. While clinical studies show that a loss of the microvascular circulation precedes and may act as an initiating factor for the development of chronic rejection, preclinical studies demonstrate that improved microvascular perfusion during acute rejection delays and attenuates tissue fibrosis. Therefore, preservation of a functional microvasculature may represent an effective therapeutic strategy for preventing chronic rejection. Here, we review recent advances in our understanding of the role of the microvasculature in the long-term survival of transplanted solid organs. We also highlight microvessel-centered therapeutic strategies for prolonging the survival of solid organ transplants.

    2017-03-01

    Full Text Available BACKGROUND The bone marrow examination is an essential investigation for the diagnosis of disorders of the blood and bone marrow. This simple and relatively safe procedure is important, particularly in resource poor centres since access to adjuvant diagnostic techniques are often lacking or absent. MATERIALS AND METHODS 189 patients of all age groups were studied for haematological and non-haematological disorders by bone marrow aspiration in the Department of Pathology, MGM Medical College during the period of 2014 to 2016. RESULTS Majority of the patients who had bone marrow aspiration were aged 0-15 years. The male-to-female ratio was 1:1.03. Most (97% of the marrow aspirate examined had definitive pathologic features, while 14 (7% were normal marrow elements. Out of 189 cases of bone marrow aspiration, acute leukaemia was the most common haematological disease diagnosed using this procedure. Acute lymphoblastic leukaemia was more common than acute myeloid leukaemia. Aplastic anaemia was seen in 16% cases. Megaloblastic anaemia occurred more commonly than other anaemias. Megaloblastic anaemia was seen in 13 cases (7% and microcytic anaemia was seen in 5 cases (3%. There were 10 cases (5% of Idiopathic Thrombocypenic Purpura. Myelodysplastic syndrome and multiple myeloma was seen in 7% and 2% cases respectively. Storage disorder was seen in 3 cases (2%, out of this 02 cases were Gaucher’s disease and one case was Niemann-Pick’s disease. CONCLUSION Bone marrow examination is an important step to arrive at the confirmatory diagnosis of many haematological disorders. This procedure remains a veritable tool in the diagnosis and management of a wide range of haematological diseases, especially in a resource poor centre.

    Full Text Available Background & objectives: Lymphadenopathy and haematological alterations are the earliest manifestations with other associated opportunistic infections and malignancies. Hence, there is a need for simple investigations like fine needle aspiration cytology (FNAC for evaluation of HIV lymphadenopathy and a haemogram to interpret the haematological alterations. This study was undertaken to analyze the cytological patterns of lymph node lesions in HIV/AIDS patients, to compare with available clinico-pathological and haematological parameters to segregate lymphadenopathy cases for further evaluation. Methods: In the present study, 129 HIV seropositive patients were included. Lymph node aspirates were stained routinely with hematoxylin and eosin and Ziehl-Neelsen (Z-N stains. Special stains and cultures were done in selected patients. Peripheral smears were taken from all the patients and CD4 counts were recorded. Tuberculous lymphadenitis was further categorized. Acid fast bacilli (AFB grading was done on Z-N positive smears. Each lesion was compared with CD4 counts, WHO clinical staging and haematological picture. Results: Cytological diagnosis in 129 patients included tuberculous (n=54, 41.9%, reactive lymphadenopathy (n=46, 35.6%, suppurative (n=16, 12.4% lymphadenitis, non-Hodgkin′s lymphoma (n=4, 3.1%, and Hodgkin′s lymphoma, secondary deposits, other granulomatous lesions, and cryptoccocal lymphadenitis in one patient each. The predominant cytomorphological pattern in tuberculous lymphadenitis was caseous necrosis + epithelioid granuloma formation (51.85%. Grade 2+ Z-N grading was noted in 62.96 per cent of AFB positive smears. CD4 counts showed a descending pattern with progression of WHO clinical staging. Cytopenia was more common in WHO clinical stage IV disease. Interpretation & conclusions: Lymph node cytology was found to be a useful tool for segregating lymphadenopathy cases for further evaluation and for identification of

    This review focuses key advances in different pediatric fields that were published in Italian Journal of Pediatrics and in international journals in 2015. Weaning studies continue to show promise for preventing food allergy. New diagnostic tools are available for identifying the allergic origin of allergic-like symptoms. Advances have been reported in obesity, short stature and autoimmune endocrine disorders. New molecules are offered to reduce weight gain and insulin-resistance in obese children. Regional investigations may provide suggestions for preventing short stature. Epidemiological studies have evidenced the high incidence of Graves' disease and Hashimoto's thyroiditis in patients with Down syndrome. Documentation of novel risk factors for celiac disease are of use to develop strategies for prevention in the population at-risk. Diagnostic criteria for non-celiac gluten sensitivity have been reported. Negative effect on nervous system development of the supernumerary X chromosome in Klinefelter syndrome has emerged. Improvements have been made in understanding rare diseases such as Rubinstein-Taybi syndrome. Eltrombopag is an effective therapy for immune trombocytopenia. Children with sickle-cell anemia are at risk for nocturnal enuresis. Invasive diseases caused by Streptococcus pyogenes are still common despite of vaccination. No difference in frequency of antibiotic prescriptions for acute otitis media between before the publication of the national guideline and after has been found. The importance of timing of iron administration in low birth weight infants, the effect of probiotics for preventing necrotising enterocolitis and perspectives for managing jaundice and cholestasis in neonates have been highlighted. New strategies have been developed to reduce the risk for relapse in nephrotic syndrome including prednisolone during upper respiratory infection.

    Although rabbit anti-T-lymphocyte globulin (ATLG) is largely used for the prevention of immune-mediated complications in patients given allogeneic haemopoietic stem-cell transplantation (HSCT) from an unrelated donor, the optimum dose of this drug in children is still undefined. We aimed to test whether a higher dose of ATLG was superior to a lower dose for prevention of grade II-IV acute graft-versus-host disease (GVHD). We conducted a multicentre, randomised, open-label, phase 3 trial in seven Italian centres comparing two different doses of ATLG (30 mg/kg vs 15 mg/kg, given intravenously over 3 days, from day -4 to -2) in children (aged 0-18 years) with haematological malignancies transplanted from an unrelated donor, selected using high-resolution typing for HLA-class I/II loci. All patients received a myeloablative regimen and cyclosporine-A plus short-term methotrexate as post-transplantation GVHD prophylaxis. Patients were randomly assigned (1:1) to either of the two groups and were stratified by the degree of HLA-compatibility with their donor, the source of haemopoietic stem cells used (bone marrow vs peripheral blood stem cells), and the disease risk category. The randomisation was open label; all investigators were aware of the treatment allocation. The primary endpoint of the study was 100-day cumulative incidence of grade II-IV acute GVHD. Statistical analyses were done according to the per-protocol principle. Other outcomes included cumulative incidence of chronic GVHD, non-relapse mortality, disease recurrence, and probability of overall survival and event-free survival. This study was registered with ClinicalTrials.gov, number NCT00934557. Between Jan 15, 2008, and Sept 25, 2012, 89 patients were randomly assigned to the 30 mg/kg ATLG group and 91 to the 15 mg/kg ATLG group; 84 patients in the 30 mg/kg ATLG group and 88 in the 15 mg/kg ATLG group were included in the analysis.

    Invasive mould infections (IMI) are a persistent problem with high morbidity and mortality rates among patients receiving chemotherapy for hematological malignancies and hematopoietic stem cell transplant recipients. Management of IMI in this setting has become increasingly complex with the advent of new antifungal agents and diagnostic tests, which have resulted in different therapeutic strategies (prophylactic, empirical, pre-emptive, and directed). A proper assessment of the individual risk for IMI appears to be critical in order to use the best prophylactic and therapeutic approach and increase the survival rates. Among the available antifungal drugs, the most frequently used in the hematologic patient are fluconazole, mould-active azoles (itraconazole, posaconazole and voriconazole), candins (anidulafungin, caspofungin and micafungin), and lipid formulations of amphotericin B. Specific recommendations for their use, and criteria for selecting the antifungal agents are discussed in this paper. Copyright © 2014. Published by Elsevier Espana.

    Full Text Available BackgroundHIV infection is associated with a wide range of haematological abnormalities.Methods and ObjectivesThe objectives in this study were to study haematological changes in HIV patients and to correlate them with CD4 cell counts. Two hundred and fifty HIV positive patients referred to the haematology laboratory section for complete haemogram in whom CD4 count was done were included in the study. Haematologic parameters and CD4 counts were studied in each of these patients.Descriptive statistics were applied. Association between two attributes was calculated by chi-square test and p value less than 0.05 was considered statistically significant.ResultsAmong 250 patients, anaemia was seen in 210 (84% cases. The most common type was normocytic normochromic (40.4%. Lymphopenia was seen in 163 (65.2% cases and thrombocytopenia in 45 (18% cases. The majority of cases (70% had CD4 cell counts below 200 cells/mm3. Fifty-four cases (21.6% had CD4 counts between 200 to 499 cells/mm3 and 21 (8.4% cases had CD4 counts more than 500 cells/ mm3.In patients with CD4 counts less than 200 cells/mm3, anaemia was seen in 91.4% cases, leucopenia in 26.8%cases, lymphopenia in 80% cases and thrombocytopenia in 21.7% cases.ConclusionHaematologic manifestations of HIV infection are common and more frequent with progression of disease. The present study revealed a significant increase in the number of cases of anaemia, and lymphopenia, with decreasing CD4 cell counts. Thrombocytopenia is also seen but does not show significant increase with disease progression. The study also highlights the importance of simultaneously treating HIV patients for haematologic manifestations to reduce morbidity.

    A high level of support for tissue banking has been identified amongst both the general public and patients. However, much debate remains about the regulatory framework of tissue banks. This study explored the views of haematological cancer patients regarding tissue banking and how tissue banks should operate. Haematological cancer patients from three outpatient clinics in Australia completed a questionnaire examining their preferences for tissue banking as well as items about their sociodemographic characteristics, disease and treatment history. The majority of participants (95%) reported being willing to allow their leftover tissue to be used for medical research. Three quarters (76%) supported the idea of their medical record being linked to their tissue sample, and 77% preferred a blanket (one-off) consent model for future research use of their tissue sample. Only 57 (27%) participants had been asked to give a tissue sample for research, 98% of whom gave permission. The majority of haematological cancer patients are willing to donate their leftover tissue to a tissue bank and have their medical records linked to tissue samples and prefer a one-off consent process. These novel data from potential donors inform the debate about how tissue banks might operate.

    Home is considered the preferred place of death for many, but patients with haematological malignancies (leukaemias, lymphomas and myeloma) die in hospital more often than those with other cancers and the reasons for this are not wholly understood. We examined preferred and actual place of death among people with these diseases. The study is embedded within an established population-based cohort of patients with haematological malignancies. All patients diagnosed at two of the largest hospitals in the study area between May 2005 and April 2008 with acute myeloid leukaemia, diffuse large B-cell lymphoma or myeloma, who died before May 2010 were included. Data were obtained from medical records and routine linkage to national death records. 323 deceased patients were included. A total of 142 (44%) had discussed their preferred place of death; 45.8% wanted to die at home, 28.2% in hospital, 16.9% in a hospice, 5.6% in a nursing home and 3.5% were undecided; 63.4% of these died in their preferred place. Compared to patients with evidence of a discussion, those without were twice as likely to have died within a month of diagnosis (14.8% vs 29.8%). Overall, 240 patients died in hospital; those without a discussion were significantly more likely to die in hospital than those who had (p≤0.0001). Of those dying in hospital, 90% and 75.8% received haematology clinical input in the 30 and 7 days before death, respectively, and 40.8% died in haematology areas. Many patients discussed their preferred place of death, but a substantial proportion did not and hospital deaths were common in this latter group. There is scope to improve practice, particularly among those dying soon after diagnosis. We found evidence that some people opted to die in hospital; the extent to which this compares with other cancers is of interest. Published by the BMJ Publishing Group Limited.

    2018-01-01

    Summary The recent advent of the Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-CRISPR associated protein 9 (Cas9) system for precise genome editing has revolutionized methodologies in haematology and oncology studies. CRISPR-Cas9 technology can be used to remove and correct genes or mutations, and to introduce site-specific therapeutic genes in human cells. Inherited haematological disorders represent ideal targets for CRISPR-Cas9-mediated gene therapy. Correcting disease-causing mutations could alleviate disease-related symptoms in the near future. The CRISPR-Cas9 system is also a useful tool for delineating molecular mechanisms involving haematological malignancies. Prior to the use of CRISPR-Cas9-mediated gene correction in humans, appropriate delivery systems with higher efficiency and specificity must be identified, and ethical guidelines for applying the technology with controllable safety must be established. Here, the latest applications of CRISPR-Cas9 technology in haematological disorders, current challenges and future directions are reviewed and discussed. PMID:27619566

    Hereditary spherocytosis is a relatively common haematological disorder and will be encountered by all haematologists. The abundance of new information, dealing principally with molecular and genetic aspects of pathophysiology, is beginning to have implications for its investigation and management. While these advances have not yet exerted a large influence at therapeutic level, the promise of such advents as prenatal diagnosis make this an exciting field to watch.

    2010-01-01

    Thalassaemia syndromes are a group of hereditary disorders characterised by a genetic deficiency in the synthesis of --globin genes. The objective of this study was to determine the haematological features -thalassaemia trait (BTT), and to determine the sensitivity of Mean Corpuscular Volume (MCV), Mean Corpuscular Haemoglobin (MCH) and -thalassaemia trait. Methods: A descriptive study was conducted in Hayatabad Medical Complex, Peshawar from May 2009 to May 2010 with 203 subjects having BTT. Blood samples were collected in EDTA anti-coagulated tubes. RBC indices were taken as part of complete blood count (CBC) by haematology analyser, and Haemoglobin (Hb) electrophoresis was done to determine the HbA2 percentage. The data was collected and analyzed on statistical software for demographic details, RBC indices and HBA2 levels. Results: Out of 203 patients, 92 (45%) were males and 111 (55%) were females. Most patients tested were in the 15-45 year age group. One-hundred-sixty (79%) patients had anaemia. MCV was lower than 76 fl in all the cases. Mean MCV was 59.1 fl. MCH was low, the mean MCH being 19.3 g/dl. MCH <26 gave sensitivity of 99% in detecting BTT. We calculated MI for these cases and found out that it was <12 in 75% of cases and <15 in 197 (97%). Conclusion: Beta-thalassaemia traits present with a microcytic hypochromic blood picture, detected on simple haematology analysers as low MCV and MCH and MI which provide a beta- thalassaemia trait.

    Menstruation coupled periodic bleeding from the blood vessels, at the time of shedding of the uterine mucosa has directed interest, more especially in the haematological changes during different phases of menstrual cycle. Methods: The present study was carried out on 30 healthy female medical students in the age group of 18 to 23 years with the normal menstrual cycle of 30 +- 3 days. The various haematological parameter and electrocardiography were studied on the second, eleventh, fourteenth and twenty second day of menstrual cycle. Result: The study reveals that the total leukocyte count and total platelet count significantly increased (p<0.001) around mid cycle, however total eosinophil count significantly decreased (p<0.05) during the same period. Differential leukocyte count, bleeding time, clotting time, heart rate, P-R interval and Q-T interval did not show any significant change during different phases of menstrual cycle, although some mild changes were observed. Conclusion: This study was a moderate attempt to determine regular variation in the different haematological parameters and ECG during the different phases of menstrual cycle in normal healthy females and evaluate conflicting reports on the subjects.

    To investigate patterns of care during the last months of life of hospitalised patients who died from different haematological malignancies. Nationwide register-based study, including all hospitalised adults ≥20 years who died from haematological malignancies in France in 2010-2013. Outcomes included use of invasive cancer treatments and referral to palliative care. Percentages are adjusted for sex and age using direct standardisation. Of 46 629 inpatients who died with haematological malignancies, 24.5% received chemotherapy during the last month before death, 48.5% received blood transfusion, 12.3% were under invasive ventilation and 18.1% died in intensive care units. We found important variations between haematological malignancies. The use of chemotherapy during the last month of life varied from 8.6% among patients with chronic myeloid leukaemia up to 30.1% among those with non-Hodgkin's lymphoma (Pcare units. A high proportion of patients who died from haematological malignancies receive specific treatments near the end of life. There is a need for a better and earlier integration of the palliative care approach in the standard practice of haematology. However, substantial variation according to the type of haematological malignancy suggests that the patients should not be considered as one homogeneous group. Implementation of palliative care should account for differences across haematological malignancies. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    This study investigated the factors associated with utilization of fertility preservation and the differences in treatments and outcomes by prior chemotherapy exposure in patients with haematological diseases. This study included all 67 women with haematological diseases seen for fertility preservation consultation at two university hospitals between 2006 and 2011. Of the total, 49% had lymphoma, 33% had leukaemia, 7% had myelodysplastic syndrome and 4% had aplastic anaemia; 46% had prior chemotherapy; and 33% were planning for bone marrow transplantation, 33% pursued ovarian stimulation and 7% used ovarian tissue banking; and 48% of patients did not pursue fertility preservation treatment. All five cycle cancellations were in the post-chemotherapy group: three patients with leukaemia and two with lymphoma. Patients with prior chemotherapy had lower baseline antral follicle count (10 versus 22) and received more gonadotrophins to achieve similar peak oestradiol concentrations, with no difference in oocyte yield (10.5 versus 10) after adjustment for age. Embryo yield was similar between those who had prior chemotherapy and those who had not. Half of the patients with haematological diseases who present for fertility preservation have been exposed to chemotherapy. While ovarian reserve is likely impaired in this group, oocyte yield may be acceptable. Copyright © 2013 Reproductive Healthcare Ltd. Published by Elsevier Ltd. All rights reserved.

    2017-11-01

    Epstein-Barr virus (EBV) was the first identified human oncovirus and is also one of the most ubiquitous viral infections known with established infections in more than 90% of individuals by early adulthood. EBV establishes latency by controlling expression of the viral genome making it silent to immune surveillance. In immunocompetent individuals, up to 1% of circulating T cells are directed at maintaining control over EBV replication. In addition to being involved in oncogenesis of lymphoid and epithelial tumors in immune-competent individuals, loss of immune surveillance over EBV predisposes individuals to EBV malignancies. Lymphoid proliferations from EBV-infected B cells arise in up to 20% of recipients of solid organ transplants (SOTs). One question not answered is why, when EBV requires such active immune surveillance, EBV malignancies are not even more prevalent in severely immune-compromised individuals. A better understanding of who develops complications related to EBV and what the immunologic risks are will ultimately make it feasible to perform prophylactic trials in those at highest risk. This review summarizes our current understanding of factors in SOT recipients that predispose them to the development of an EBV malignancy and that predict response to initial therapy. We then review the current landscape of those therapies, focusing on the goal of restoring long-term EBV-directed immunity to patients at risk.

    Full Text Available Abstract This study was designed to investigate whether there is an association between Obstructive Airways Disease (OAD and indoor exposure to baking home-made bread smoke (BHBS in ground oven at home. In this hospital-based case–control study, 83 patients with OAD (cases were compared with 72 patients without any known pulmonary diseases from the surgical ward (controls who were frequently matched with cases on age. The interview was performed using the modified questionnaire recommended by the "American Thoracic Society". The questionnaire comprised of demographic information, occupational history, cigarette smoking and indoor exposure to BHBS in ground oven at home. The exposure to BHBS was considered both as a dichotomous and quantitative variable (number of years being exposed to smoke and the population attributable fraction (PAF was estimated due to BHBS exposure. The percentage of indoor exposure to BHBS was measured as 51.8% and 30.6% in the cases and the controls, respectively. The average years of exposure to BHBS was 20.46 years (SD: 11.60 for the cases and 15.38 years (SD: 13.20 for the controls. The univariate analysis comparing the cases and the controls showed that exposure to BHBS (as a binary variable and occupational exposure to dust was significantly associated with OAD. In the multivariate model, only exposure to BHBS was associated with OAD (OR=2.22, 95%CI = 1.14-4.35. Duration of exposure to BHBS (as a quantitative variable was significantly associated with OAD in the univariate model. In the multivariate model, only the duration of exposure to BHBS (years showed a significant association with OAD (OR=1.04, 95% CI=1.01-1.08. Population attributable risk due to BHBS exposure was equal to 28.5%.

    2018-01-01

    Full Text Available BACKGROUND Pancytopenia is one of the pathological manifestation resulting from various underlying disease processes affecting the bone marrow. Hence, bone marrow examination is the diagnostic tool to detect the underlying aetiology of pancytopenia. Pancytopenia nowadays has become a relatively common haematological entity. The underlying cause is ranging from simple drug-induced bone marrow hypoplasia, megaloblastic anaemia to fatal bone marrow aplasias and leukaemias. Thus, identification of the correct cause will help in implementing appropriate therapy. MATERIALS AND METHODS This was a prospective study and 158 pancytopenic patients were evaluated clinically along with haematological parameters and bone marrow aspiration in Clinical Pathology, Department of Pathology, during the period of December 2016 to December 2017. RESULTS Among 158 cases, age of patients ranged from 3 to 88 years with a mean age of 45 years and male predominance. Most of the patients presented with fever and anaemia. The commonest physical finding was pallor followed by generalised weakness and splenomegaly. Dimorphic anaemia was the predominant blood picture. Among the 158 cases, 56 cases have undergone bone marrow aspiration in the department. The commonest bone marrow finding was erythroid hyperplasia with megaloblastic maturation (25%. CONCLUSION The present study shows the detailed primary haematological investigations along with bone marrow aspiration in pancytopenia patients, which is useful in understanding disease process. These are also helpful in planning further evaluation and management.

    2012-03-01

    Patients are increasingly seeking health information on the Internet, but to the best of our knowledge, this has not been previously studied in haematology. We aimed to characterise online health information use and associated variables among adult outpatients in our tertiary-care centre in Flanders, Belgium. During a 6-week period, we distributed 477 anonymous self-administered questionnaires and received 451 (response rate 94.5%), of which 444 (93.1% of total) contained information on Internet use for health information, the primary outcome. Two hundred and thirty-two respondents (52.3%) had ever sought any health information online, and 187 (33.1%) conducted searches pertaining to their haematological disease in the past year. The latter was independently associated with younger age and a higher level of education in multivariate analysis. Internet users ranked the Internet higher and other resources lower as health information resources. Among Internet users, 196 (89.5%) would be interested in a list of reliable websites about their disease. Patients reported positive and negative aspects of online health information-seeking; it increased anxiety in some while it stimulated coping in others. We conclude that haematological patients commonly use the Internet for health information and report both positive and negative aspects of using this medium.

    Full Text Available Haemoparasites reduces productivity and may lead to high mortality among animals. The present study was carried out to evaluate the heamotological change in cattle of different districts in West Bengal, India affected with naturally occurring tick- borne haemoparasitic diseases (TBHD. A total of 310 cattle blood samples were screened for the presence of haemoparasites from July, 2015 to June, 2016. The blood samples were examined for haemoparasites by making thin blood smear and staining with Giemsa’s stain. The result showed that108 (34.84% cattle were found positive with TBHD, out of which 22.9% were Theileria sp, 5.8% were Babesia sp., 11.93% Anaplasma sp., and 5.8% were having mixed infection, respectively. The positive samples were subjected to estimations of haematological parameters i. e. Haemoglobin concentration (Hb, packed cell volume (PCV, total erythrocyte count (TEC and Total leucocytes count (TLC using standard protocol. The haematological analysis showed statistically a significant (p<0.01 decreased levels of Hb, PCV, TEC and TLC in infected groups of cattle compared to infection free group cattle. This is probably the first systematic report in West Bengal, India. The result showed the haemoparasites have a negative impact on haematological parameters. This study may be useful in disease epidemiological map preparation, parasitic control policy preparation of the study areas.

    Anorectal complications are common in patients with haematological malignancies. The objectives are to characterize anorectal complications in these patients, identify risk factors and shed light on treatment, morbidity and mortality rates. A retrospective, observational study that included 83 inpatients with haematological malignancies and proctological symptoms from January 2010 to September 2015 was conducted. Clinical outcomes were obtained through a detailed review of medical records. The median age was 56 years, and 52 (62.7%) patients were men. Fifty-six (67.5%) patients had nonseptic anorectal complications and 27 (32.5%) patients had septic anorectal complications. Patients with septic anorectal complications were more commonly male, older, and had lower absolute neutrophil counts, but the differences were not statistically significant (P=0.79, 0.67 and 0.89, respectively). In positive blood cultures [23/70 (32.9%)], Enterococcus faecium, Klebsiella pneumonia, and Escherichia coli were the most common isolated agents. In nonseptic anorectal complications, conservative treatments/minor proctological procedures were adopted, and patients with septic anorectal complications were treated with antibiotics±major proctological procedures and/or surgical drainage/debridement. Forty-eight (85.7%) patients in the nonseptic complications group improved compared with 23 (85.2%) patients in the septic complications group. The overall mortality rate was 2.4% (n=2), with one (1.2%) death related to perianal sepsis. Enterococcus spp. were more commonly identified in this study and can be increasing in this specific population. In contrast to other reports, we did not identify an association between septic anorectal complications and possible risk factors such as male sex, younger age or a low absolute neutrophil count. Most patients had nonseptic anorectal complications. A major proctological procedure/surgical debridement should always be applied in septic complications

    Determination of serum thymidine kinase 1 (STK1) activity has been used as a proliferation marker for neoplastic diseases in both human and veterinary medicine. The purpose of this study was to determine STK1 activity and enzyme levels in different dog tumours. Serum samples from three dogs with leukaemia, five with lymphoma, 21 with solid tumours and 18 healthy dogs were analyzed for STK1 activity, using an optimized [(3)H]-deoxythymidine (dThd) phosphorylation assay, and for STK1 protein levels using an immunoaffinity/western blot assay. STK1 activity in dogs with haematological tumours was significantly higher than in the solid tumour and healthy dog groups (mean ± standard deviation [SD] = 65 ± 79, 1.1 ± 0.5, and 1.0 ± 0.4 pmol/min/mL, respectively). Serum samples were analyzed after immunoaffinity isolation by western blot and the TK1 26 kDa band intensities quantified revealing that concentrations were significantly higher in dogs with haematological tumours and solid tumours compared to healthy dogs (mean ± SD=33 ± 12, 30 ± 13, and 10 ± 5 ng/mL, respectively). Pre-incubation with the reducing agent dithioerythritol (DTE) showed a decrease in STK1 activity and protein levels in most samples, but an increase of about 20% in sera from healthy dogs and from those with haematological malignancies. Compared to animals with solid tumours, the specific STK1 activity (nmol [(3)H]-deoxythymidine monophosphate (dTMP)/min/mg of TK1 protein of 26 kDa) was 30-fold higher in haematological malignancies and 2.5-fold higher in healthy dogs, respectively. The results demonstrate that there is a large fraction of inactive TK1 protein, particularly in sera from dogs with solid tumours. The findings are important in the use of STK1 as a biomarker.

    Haematological, ocular and skeletal abnormalities were documented in a samoyed male and its five offspring. Haematological abnormalities, found in repeated tests in all the dogs, included marked eosinophilia, eosinophilic bands and absence of Barr bodies. Two of the dogs had bilateral buphthalmia, retinal detachments and other ocular abnormalities. Three of the dogs had skeletal abnormalities including chondrodysplasia (dwarfism) and brachygnathia (undershot jaw). A similar combination of inherited skeletal and ocular disorders, without the haematological abnormalities, has been described in samoyeds. Acquired causes for the haematological findings, which are similar to the inherited Pelger-Huët anomaly described in several species, have been eliminated. Eosinophilic bands and scarcity of Barr bodies could be a marker, or a previously unreported manifestation, of an inherited disorder in samoyeds

    Patients with haematological malignancies have a poorer labour market prognosis than the general population. We have previously found that they have low rates of return to work, and a higher risk of being granted disability pension, than individuals without a history of these diseases. The aim of this study was to further investigate the labour market prognosis for these patients, by comparing the risk of being granted wage-subsidised (WS) employment as a result of permanently reduced work capacity among patients diagnosed with haematological malignancies to a reference cohort, and to determine if relative risks differ between subtypes of haematological malignancies. We combined data from national registers on Danish patients diagnosed with haematological malignancies between 2000 and 2007 and a reference cohort without a history of these diseases. A total of 3194 patients and 28 627 reference individuals were followed until they were granted WS employment, disability pension, anticipatory pension, old age pension, emigration, death or until 26 February 2012, whichever came first. A total of 310 (10%) patients and 795 (3%) reference individuals had their work capacity permanently reduced to an extent that they were granted WS employment during the follow-up period. Age- and gender-adjusted relative risks differed significantly between the subgroups of haematological malignancies, and four years after diagnosis they ranged from 2.47 (95% CI 1.46-4.16) for patients with Hodgkin lymphoma to 10.83 (95% CI 7.15-16.40) for patients with chronic myeloid leukaemia. All eight subtypes of haematological malignancies were associated with an increased risk of being granted WS employment due to permanently reduced work capacity compared to the reference cohort. The relative risks differed according to haematological malignancy subtype, and the highest was found for patients with chronic myeloid leukaemia.

    Full Text Available Decreasing of harpy eagle (Harpia harpyja populations in natural environments, mainly in non-preserved areas, makes captive population management an important contribution to genetic diversity conservation. The aim of this study is to evaluate hematological parameters for captive harpy eagles maintained at the wild animals breeding center of Itaipu Binacional, Paraná State, Brazil. Fourteen blood samples from nine harpy eagles were collected from animals of both sexes, of different ages and with no clinical signs of disease. Significant variations were found in haematological values of hematocrit, hemoglobin, mean corpuscular hemoglobin (MCH, mean corpuscular hemoglobin concentration (MCHC, leukocyte, a relative number of heterophils, absolute and relative number of lymphocytes, monocytes, eosinophils, basophils and plasma protein between groups of young (less than six months old and adult birds. Comparing males and females there was variation in the values of erythrocytes, hemoglobin, mean corpuscular volume (MCV, mean corpuscular hemoglobin (MCH on heterophils, absolute and relative number of lymphocytes, eosinophils and basophils. There was also variation in the values of red blood cells, hematocrit, hemoglobin, mean corpuscular volume (MCV, mean corpuscular hemoglobin (MCH, mean corpuscular hemoglobin concentration (MCHC, leukocyte count, absolute number of lymphocytes, eosinophils and basophils among birds that study compared to another reference birds. Due to the limited information available on harpy eagle hematology, this study will be useful to the clinical assessment of birds maintained in captivity.

    Full Text Available Abstract Background Patients with Crohn’s disease (CD have been shown to present dyspeptic symptoms more frequently than the general population. Some of these symptoms could be related to motility disorders to some degree. Then, we propose to investigate whether gastric emptying of solids in patients with inactive CD is delayed and to determine the relationships between gastric emptying and dyspeptic symptoms in inactive CD. Methods Twenty-six patients with inactive Crohn’s disease, as defined by a Crohn’s Disease Activity Index (CDAI 13C octanoic acid coupled to a solid meal and answered a validated questionnaire (The Porto Alegre Dyspeptic Symptoms Questionnaire to assess dyspeptic symptoms. Patients with scores ≥ 6 were considered to have dyspepsia. The control group was composed by 19 age- and sex-matched healthy volunteers. Results Patients with CD had a significantly longer t 1/2 and t lag (p Conclusion Delayed gastric emptying in inactive Crohn’s disease patients seems to be associated with dyspeptic symptoms, particularly vomiting, even without any evidence of gastrointestinal obstruction.

    Arnaud, J; Quilici, J C; Rivière, G

    1981-01-01

    Haematological studies have been carried out at various altitudes between 450 m and 4800 m, on two separate human groups (Quechuas and Aymaras) living in South America. Changes in the haematological parameters do not develop linearly in relation to the attitude. Th impact of chronic hypoxia on erythropoiesis is greater above 3000 m. The haemogram varies quantitatively and not qualitatively (mean corpuscular volume and mean haemoglobin concentration remain constant). The haematological study also reveals the greater adaptability to high altitude of the Aymaras, an adaptability characterized by an increase in red cell count and concentration and a decrease in red cell volume. The adaptative phenomena observed in the Quechuas are reversible, whereas they persist in the Aymaras when they migrate to the lowlands (450 m).

    Full Text Available Aim: Behcet%u2019s disease is a multisystemic disease that includes the mucocutaneous, ocular, cardiovascular, renal, pulmonary, joint and central nervous system involvement. Gastrointestinal system involvement is rare in Behcet%u2019s disease. Current study was planned to investigate the rate of gastric emptying in patients with Behcet%u2019s disease by using gastric emptying scintigraphy. Material and Method: In order to determine gastric emptying rate of solids, 14 patients with Behcet%u2019s disease and 14 healthy controls were studied scintigraphically. After an overnight fast, all subjects ingested a Tc- 99m DTPA labeled solid meal consisted of an egg and toasted white bread. Immediately after ingestion of the meal, subjects were positioned supine under the gamma camera and serial images were recorded continuously for 90 minutes. Half empyting time (t 1/2 and percentage of radioactive material remaining in the stomach at 60 min. were calculated. Results: The mean ages of Behcet%u2019s patients was 41.00±10.25 years and 40.57±10.05 years in control group. T ½ of Behcet%u2019s patients was found 85± 61 min. and 63±22 min. in control cases (p=0.122. Percentage of radioactive material remaining in the stomach at 60 min. was 69.3± 14.0 % and 54.6± 22.0 % in Behcet%u2019s patients and controls, respectively (p=0.035. Discussion: Although there was not a significant difference between half gastric emptying times, we determined that percentage of radioactive material remaining in the stomach at 60 min. was significantly greater in Behcet%u2019s patients than that in controls. As a result, gastric stasis could be seen in Behcet%u2019s patients due to multisystemic involvement.

    Abstract Nuclear diagnostic techniques have revolutionized medicine in its different specialties, among them hematology. This is, by the more relevant routine procedures of diagnostic as well as by future trends in this field, in-vivo research and clinical applications at the biochemical level. We report a part of our experience by the use in vitro and in vivo established nuclear medicine techniques, in evaluating hematological disease for clinical research that will lead to the basic research. The first study is megaloblastic anemia in which we report a prospective study from Tunisia, northern Africa, of 478 patients with megaloblastic anemia recruited over three years period. Etiologic investigation using cobalamin and folates measurements and the Schilling test revealed that folate deficiency was very uncommon and that 95% of patients had cobalamin deficiency that was the consequence of pernicious anemia (PA) in 87%. Patients with PA had a median age at presentation of 45.5 years with 21.5% of cases occurring in patients younger than 30 years. Patients less than 20 years old should be specifically investigated for genetic defect in cobalamin absorption. In the second study, the red cell mass was determined following labeling the red blood cells with either sodium radiochromate (51Cr) and the measurement of Plasma Volume is based on dilution of the injected radioiodine (125I)-labeled human serum albumin in the blood circulation (2,3). It is important to make this differentiation, thus our patients will fulfilled the criteria of the Polycythemia Vera Study Group, and therefore we will be able to evaluate serum VEGF levels in patients with Polycythemia Vera, secondary polycythemia and idiopatic polycythemia in an attempt to investigate the involvement and significance of this cytokine in these haematological disorders.

    Evaluation of the health status of free-ranging populations is important for understanding the impact of disease on individuals and on population demography and viability. In this study, haematological reference intervals were developed for free-ranging endangered Australian sea lion (Neophoca cinerea) pups within the context of endemic hookworm (Uncinaria sanguinis) infection and the effects of pathogen, host, and environment factors on the variability of haematological parameters were investigated. Uncinaria sanguinis was identified as an important agent of disease, with infection causing regenerative anaemia, hypoproteinaemia, and a predominantly lymphocytic-eosinophilic systemic inflammatory response. Conversely, the effects of sucking lice (Antarctophthirus microchir) were less apparent and infestation in pups appears unlikely to cause clinical impact. Overall, the effects of U. sanguinis, A. microchir, host factors (standard length, body condition, pup sex, moult status, and presence of lesions), and environment factors (capture-type and year of sampling) accounted for 26-65% of the total variance observed in haematological parameters. Importantly, this study demonstrated that anaemia in neonatal Australian sea lion pups is not solely a benign physiological response to host-environment changes, but largely reflects a significant pathological process. This impact of hookworm infection on pup health has potential implications for the development of foraging and diving behaviour, which would subsequently influence the independent survival of juveniles following weaning. The haematological reference intervals developed in this study can facilitate long-term health surveillance, which is critical for the early recognition of changes in disease impact and to inform conservation management.

    Full Text Available The semi-domestic reindeer is a ruminant which exhibits a highly advanced adaptation to the marked seasonality of the northern environment. Since the reindeer has an economic importance and previous information about its blood composition is scanty in respect to age, season, calving and nutrition, the haematology of 578 reindeer were studied. The blood samples were taken from the jugular vein mainly in connection with the marking of calves during summer and at reindeer round-ups in autumn and winter at 10 reindeer rearing subunits in Northern Finland in various seasons in 1973-79. The red blood cell count (8xl012/l, haemoglobin (108 g/1, packed cell volume (35%, white blood cell count (6x109/l and serum iron (26 micromol/1 were low in newborn calves and reached their adult levels in autumn at the age of 5 months (average 11 x 1012/1, 182 g/1, 51%, 9x109/l, 44 micromol/1, respectively. The total serum bilirubin was relatively stable and vitamin B12 high in the first days after birth. The stable serum bilirubin indicates a relatively small breakdown of foetal erythrocytes. E-MCV of adult females was about 49 fl and the diameter of round erythrocytes about 5.5 microm and their thickness about 1.5 microm. No sickling was observed. The red cell osmotic fragility had a initial and final haemolysis points of 0.71 and 0.37% NaCl solution. The relative proportions of neutrophil, eosinophil and basophil granulocytes and agranular lymphocytes and monocytes were 52, 5, 2, 42 and 2 %, respectively. The calving of the reindeer occurs without visible haemorrhage. The body weight, red blood cell count, haemoglobin, packed cell volume and serum iron of pregnant hinds dropped, however, during the early lactation period, and a relative anaemia developed is partly due to iron deficiency and, perhaps, also breakdown of foetal erythrocytes. The means of body weight (range 50-70 kg, red blood cell count (8-11 x 1012/l, haemoglobin (118-185 g/1, packed cell volume (42

    2016-06-01

    Full Text Available Use of current models of Automated Haematology Analysers help in calculating the haemoglobin contents of the mature Red cells, Reticulocytes and percentages of Microcytic and hypochromic Red cells. This has helped the clinician in reaching early diagnosis and management of Different haemopoietic disorders like Iron Deficiency Anaemia, Thalassaemia and anaemia of chronic diseases. AIM This study is conducted using an Automated Haematology Analyser to evaluate anaemia using the Red Cell and Reticulocyte parameters. Three types of anaemia were evaluated; iron deficiency anaemia, anaemia of long duration and anaemia associated with chronic disease and Iron deficiency. MATERIALS AND METHODS The blood samples were collected from 287 adult patients with anaemia differentiated depending upon their iron status, haemoglobinopathies and inflammatory activity. Iron deficiency anaemia (n=132, anaemia of long duration (ACD, (n=97 and anaemia associated with chronic disease with iron deficiency (ACD Combi, (n=58. Microcytic Red cells, hypochromic red cells percentage and levels of haemoglobin in reticulocytes and matured RBCs were calculated. The accuracy of the parameters was analysed using receiver operating characteristic analyser to differentiate between the types of anaemia. OBSERVATIONS AND RESULTS There was no difference in parameters between the iron deficiency group or anaemia associated with chronic disease and iron deficiency. The hypochromic red cells percentage was the best parameter in differentiating anaemia of chronic disease with or without absolute iron deficiency with a sensitivity of 72.7% and a specificity of 70.4%. CONCLUSIONS The parameters of red cells and reticulocytes were of reasonably good indicators in differentiating the absolute iron deficiency anaemia with chronic disease.

    Full Text Available Primary infection with Epstein-Barr virus (EBV usually occurs in early childhood and often does not present clinical symptoms. More than 90% of adults are infected with this virus. A primary infection that occurs in adolescence or adulthood is usually clinically presented as infectious mononucleosis with a triad of symptoms: fever, lymphadenopathy and pharyngitis. Our retrospective study included 51 patients with a median age of 17 (9-23 years and serologically confirmed infectious mononucleosis. All patients with infectious mononucleosis were treated at the Clinic for Infectious Diseases at the Clinical Center in Kragujevac during 2013. We analysed the clinical, haematological and laboratory parameters of patients. The aspartate-aminotransferase levels were increased in 40 patients, with a mean value of 116.24 (±93.22; the alanine-aminotransferase levels were increased in 44 patients, with a mean value of 189.24 (±196.69. Lymphadenopathy was the most common clinical feature upon admission in 49 patients (96%; 38 patients (74.5% had splenomegaly, and 20 (39% had hepatomegaly. Twenty-six patients (51% had leukocytosis with lymphocytosis, while 15 (75% of the 20 who had a normal leukocyte count also had lymphocytosis. In the present study, we updated the clinical, haematological and laboratory parameters, which may lead to the establishment of an accurate diagnosis and promote further treatment of the patients.

    1980-06-01

    A direct solid-phase radioimmunoassy (dRIA) was developed in order to demonstrate antibodies against Aujeszky's disease virus (ADV) in sera obtained from pigs and rabbits. In the presence of guinea-pig complement the above test is 160-fold to 1500-fold more sensitive than the neutralization test (NT) and 320-fold to 150 000-fold more sensitive than sera obtained from an ADV-infected farm, which were found to be negative in the complement assisted NT. It is possible to test a single dilution of unknown serum by dRIA by comparing same with a standard curve and to make a statement regarding its ADV-specific binding capacity to /sup 125/I-labelled ADV antigen. The advantages of dRIA in comparison to the indirect RIA and the advantages and disadvantages with regard to ELISA were discussed.

    Polyphenols of natural and synthetic origin are exploited in tanning sector to convert putrescible skin/hide to non-putrescible leather. However, only 30-40% of the inputs have been taken up for processing, the remaining is released as unspent. The existing conventional wastewater treatment systems are inefficient in removing or degrading these unspent polyphenols and thus detrimental to ecosystem. The present study demonstrates the evaluation of impact of both synthetic and natural polyphenols on biochemical and haematological properties of blood and serum in animal models. The results reveal that concentrations of polyphenols play a major role. At higher concentrations, irrespective of their nature, there was a marked change in the lipid profile (81% reduction), followed by insignificant change in glucose levels, RBC and WBC counts and other haematological parameters. At lower concentrations, no significant changes in the above said properties were observed.

    Kamiyama, Ryuichi; Hatakeyama, Shigeru

    1989-01-01

    Fifteen haematological disorders including ten leukaemia cases, one primary acquired sideroblastic anaemia and four aplastic anaemia cases were studied clinicopathologically in autopsies from patients who had been administered Thorotrast in Japan. The leukaemia group, the primary acquired sideroblastic anaemia and the aplastic anaemia cases after Thorotrast administration were considered to be mainly atypical, and it was speculated that damage induced by Thorotrast may affect the haemopoietic stem cell level and the haemopoietic microenvironment. Both dose rate and absorbed dose estimated in bone marrow, spleen and liver at autopsy showed no significant difference between the leukaemia group, primary acquired sideroblastic anaemia, aplastic anaemia and non-haematological disorders excluding the malignant hepatic tumours and liver cirrhosis.

  19. The role of extracellular histones in haematological disorders.

    Science.gov (United States)

    Alhamdi, Yasir; Toh, Cheng-Hock

    2016-06-01

    Over the past decades, chromosomal alterations have been extensively investigated for their pathophysiological relevance in haematological malignancies. In particular, epigenetic modifications of intra-nuclear histones are now known as key regulators of healthy cell cycles that have also evolved into novel therapeutic targets for certain blood cancers. Thus, for most haematologists, histones are DNA-chained proteins that are buried deep within chromatin. However, the plot has deepened with recent revelations on the function of histones when unchained and released extracellularly upon cell death or from activated neutrophils as part of neutrophil extracellular traps (NETs). Extracellular histones and NETs are increasingly recognized for profound cytotoxicity and pro-coagulant effects. This article highlights the importance of recognizing this new paradigm of extracellular histones as a key player in host defence through its damage-associated molecular patterns, which could translate into novel diagnostic and therapeutic biomarkers in various haematological and critical disorders. © 2016 John Wiley & Sons Ltd.

  5. Changing haematological parameters in dengue viral infections

    International Nuclear Information System (INIS)

    Jamil, T.; Mehmood, K.; Mujtaba, G.; Choudhry, N.

    2012-01-01

    Background: Dengue Fever is the most common arboviral disease in the world, and presents cyclically in tropical and subtropical regions of the world. The four serotypes of dengue virus, 1, 2, 3, and 4, form an antigenic subgroup of the flaviviruses (Group B arboviruses). Transmission to humans of any of these serotypes initiates a spectrum of host responses, from in apparent to severe and sometimes lethal infections. Complete Blood count (CBC) is an important part of the diagnostic workup of patients. Comparison of various finding in CBC including peripheral smear can help the physician in better management of the patient. Material and Methods: This cross sectional study was carried out on a series of suspected patients of Dengue viral infection reporting in Ittefaq Hospital (Trust). All were investigated for serological markers of acute infection. Results Out of 341 acute cases 166 (48.7%) were confirmed by IgM against Dengue virus. IgG anti-dengue was used on 200 suspected re-infected patients. Seventy-one (39.5%) were positive and 118 (59%) were negative. Among 245 confirmed dengue fever patients 43 (17.6%) were considered having dengue hemorrhagic fever on the basis of lab and clinical findings. Raised haematocrit, Leukopenia with relative Lymphocytosis and presence atypical lymphocytes along with plasmacytoid cells was consistent finding at presentation in both the patterns of disease, i.e., Dengue Haemorrhagic fever (DHF) and Dengue fever (DF). Conclusion: Changes in relative percentage of cells appear with improvement in the symptoms and recovery from the disease. These findings indicate that in the course of the disease, there are major shifts within cellular component of blood. (author)

We measured gastric emptying of both the liquid and solid components of a meal in 10 consecutive patients with chronic liver disease and portal hypertension, but free of ascites, and 14 age- and sex-matched healthy controls. In the patients with liver disease, relationships between emptying and liver function were examined. To measure gastric emptying, subjects consumed a test meal that consisted of scrambled eggs labeled with 99mTc-sulfur colloid and 4 oz of water labeled with 111In-diethylene triamine pentacetic acid (DTPA). Patients with liver disease and portal hypertension demonstrated delayed emptying of both the liquid (t1/2, min, mean +/- SE, patients vs. 69.4 +/- 19.4 vs. 31.4 +/- 1.8, p < 0.01) and solid (post-lag phase solid emptying: 141 +/- 32.9 vs. 69.8 +/- 4.6, p < 0.006) components of the meal. We could not identify any correlation between gastric emptying and tests of liver function. Gastric emptying is delayed in patients with liver disease and portal hypertension; this abnormal gastric motor function may contribute to the pathophysiology of foregut complaints in this patient population.

    The chief application is the use of radiophosphorus in myelo-proliferative syndromes. Polycythemia is practically the only disease for which 32 P therapy is indicated. The methods, results obtained and possible immediate or long-term complications of 32 P treatment are described. Immediate complications are few, the general tolerance excellent. Long-term haematological complications are responsible, in all statistics, for about 30% of the deaths recorded in polycythemia cases treated with 32 P, caused about equally by acute myeloblastic leukemia and myeloid splenomegaly. It is considered that the risk of transformation to leukemia is undoubtedly aggravated by the use of radioactive phosphorus [fr

    Invasive pulmonary aspergillosis as a cause of mortality and morbidity in patients with haematological malignancies is becoming more common. Predisposing factors are powerful immunosuppressive chemotherapy, neutropenia and synergistic combinations of antibiotics of great potency and wide spectrum of activity. Clinical and radiological signs are heterogeneous, sometimes misleading and often absent. Treatment is often empirical on suspicion alone. Amphotericin B is the only effective drug but it has marked toxicity, mainly renal. Infection is usually fatal without adequate treatment. This paper describes eight cases of invasive pulmonary aspergillosis seen in one centre in two years, reviews the literature and assesses associated problems.

    The marine iguana, Amblyrhynchus cristatus, is an iconic lizard endemic to the Galápagos Islands of Ecuador, but surprisingly little information exists on baseline health parameters for this species. We analysed blood samples drawn from 35 marine iguanas captured at three locations on San Cristóbal Island. A portable blood analyser (iSTAT) was used to obtain near-immediate field results for pH, lactate, partial pressure of O2, partial pressure of CO2, bicarbonate (HCO3−), percentage O2 saturation, haematocrit, haemoglobin, sodium, potassium, ionized calcium and glucose. Parameter values affected by temperature were auto-corrected by the iSTAT. Standard laboratory haematology techniques were employed for differential white blood cell counts and haematocrit determination; resulting values were also compared with the haematocrit values generated by the iSTAT. Body temperature, heart rate, respiratory rate and body measurements were also recorded. Body length was positively correlated with several blood chemistry values (HCO3− and glucose) and two haematology parameters (haemoglobin and manually determined haematocrit). A notable finding was the unusually high blood sodium level; the mean value of 178 mg/dl is among the highest known for any reptile. This value is likely to be a conservative estimate because some samples exceeded the maximal value the iSTAT can detect. For haematocrit determination, the iSTAT blood analyser yielded results significantly lower than those obtained with high-speed centrifugation. The values reported in this study provide baseline data that may be useful in comparisons among populations and in detecting changes in health status among marine iguanas affected by natural disturbances or anthropogenic threats. The findings might also be helpful in future efforts to demonstrate associations between specific biochemical parameters and disease. PMID:27293719

    To provide insight into the perceived need for information of patients with haematological malignancies. Providing timely and accurate information to patients diagnosed with a haematological malignancy is a challenge in clinical practice; treatment often has to start promptly, with little time to inform patients. Literature review. A comprehensive literature search was conducted from all available literature to May 2013 in the databases: Cumulative Index to Nursing and Allied Health Literature, PsycINFO and PubMed (Medline). Relevant studies were reviewed regarding the perceived need for information on various topics, sources of information and satisfaction with information provided. The initial search revealed 215 articles, fourteen of which were relevant. Patients need basic information on the disease (diagnosis and diagnostics), treatment (various treatment options, side effects and duration), prognosis (curability and prolonging life) and all other topics (recovery, self-care and psychosocial functioning). Need for detailed information varied between studies. Patients expressed a higher need for medical than for psychosocial information. Patients preferred to receive information from their doctors the most, followed by nurses. Most studies described patients' satisfaction with the information provided. Based on the limited number of data available, medical information is for patients of higher priority compared to psychosocial information. Patients need basic information on diagnosis, treatment, prognosis and all other topics. Need for detailed information varied between studies. Patients were satisfied with the provided information, preferably offered by doctors and nurses. The perceived need for information and satisfaction with the information provided differs strongly between patients. In clinical practice, more attention is needed for information tailored to the patient, taking into account important moderating factors such as age, type of cancer, time

    To examine the advantage of liver and brain MRI in clinically anomalous haematological patients with fever of unknown origin. Material and Methods: Twenty liver MRI (T 2 -TSE, T 2 -HASTE, T 1 -FLASH±Gd dynamic) and 16 brain MRI (T 2 -TSE, FLAIR, T 1 -TSE±Gd) were performed searching for a focus of fever with a suspected organ system. Comparison with clinical follow-up. Results: suspected organ system. Comparison with clinical follow-up. Results: A focus was detected in 11/20 liver MRI. Candidiasis (n=3), mycobacteriosis (n=2), relapse of haematological disease (n=3), graft versus host disease (n=1), non-clarified (n=2). The remaining 9 cases with normal MRI were not suspicious of infectious hepatic disease during follo-wup. In brain MRI, 3/16 showed a focus (toxoplasmosis, aspergillosis, mastoiditis). Clinical indication for an infectious involvement of the brain was found in 4/16 cases 2--5 months after initially normal brain MRI. No suspicion of an infectious involvement of brain was present in the remaining 9/16 cases. Conclusion: In case of fever of unknown origin and suspicion of liver involvement, MRI of the liver should be performed due to data given in literature and its sensitivity of 100%. Because of the delayed detectability of cerebral manifestations, in cases of persisting suspicion even a previously normal MRI of the brain should be repeated. (orig.) [de

    For patients with haematological malignancies, information on disease, prognosis, treatment and impact on quality of life is of the utmost importance. To gain insight into the perceived need for information in relation to sociodemographic and clinical parameters, comorbidity, quality of life (QoL) and information satisfaction, we compiled a questionnaire based on existing validated questionnaires. A total of 458 patients diagnosed with a haematological malignancy participated. The perceived need for information was moderate to high (40-70%). Multivariate regression analyses showed that a higher need for information was related to younger age, worse QoL, being member of a patient society and moderate comorbidity. The need for disease and treatment-related information was higher than the need for psychosocial information. A higher need for disease and treatment-related information was associated to being diagnosed with multiple myeloma. A higher need for psychosocial information was related to a lower educational level. The information provision could be improved according to 41% of the patients. Higher satisfaction with provided information was associated with better QoL. Most patients (62%) reported that they wanted to be fully informed about their illness and actively involved in treatment decision-making. The results contribute to improving patient-tailored information provision and shared decision-making in clinical practice. Copyright © 2014 John Wiley & Sons, Ltd.

    The effect of canine intestinal helminths on the haematological profile of 200 dogs, of both sexes and variable age, visiting university veterinary clinics for routine examination was investigated. The dogs were assigned to parasitized (n = 39) and non-parasitized (n = 161) groups of animals. Coprological examination revealed a 19.5% prevalence of different species of the helminths. Of these animals, 10.25% had mixed infections with Ancylostoma caninum, Toxascaris spp. and Dipylidium caninum. The intensity of A. caninum infection was the highest, with mean egg counts of 951.43 (standard error 88.66), followed by Toxascaris 283.33 (standard error 116.81) and D. caninum. The parasitized animals had significantly lower levels of haemoglobin, packed cell volume and total erythrocyte counts than non-parasitized animals (P < 0.01). Values of other parameters, except for lymphocytes and eosinophils, were not different between the two groups. Analyses of the haematological profile revealed normocytic hypochromic anaemia in the parasitized group of animals.

    Background: Approximately 2.8 billion people cook with solid fuels. Research has focused on the health impacts of indoor exposure to fine particulate pollution. Here, for the 2010 Global Burden of Disease project (GBD 2010), we evaluated the impact of household cooking with solid fuels on regional population-weighted ambient PM2.5 (particulate matter ≤ 2.5 μm) pollution (APM2.5). Objectives: We estimated the proportion and concentrations of APM2.5 attributable to household cooking with solid fuels (PM2.5-cook) for the years 1990, 2005, and 2010 in 170 countries, and associated ill health. Methods: We used an energy supply–driven emissions model (GAINS; Greenhouse Gas and Air Pollution Interactions and Synergies) and source-receptor model (TM5-FASST) to estimate the proportion of APM2.5 produced by households and the proportion of household PM2.5 emissions from cooking with solid fuels. We estimated health effects using GBD 2010 data on ill health from APM2.5 exposure. Results: In 2010, household cooking with solid fuels accounted for 12% of APM2.5 globally, varying from 0% of APM2.5 in five higher-income regions to 37% (2.8 μg/m3 of 6.9 μg/m3 total) in southern sub-Saharan Africa. PM2.5-cook constituted > 10% of APM2.5 in seven regions housing 4.4 billion people. South Asia showed the highest regional concentration of APM2.5 from household cooking (8.6 μg/m3). On the basis of GBD 2010, we estimate that exposure to APM2.5 from cooking with solid fuels caused the loss of 370,000 lives and 9.9 million disability-adjusted life years globally in 2010. Conclusions: PM2.5 emissions from household cooking constitute an important portion of APM2.5 concentrations in many places, including India and China. Efforts to improve ambient air quality will be hindered if household cooking conditions are not addressed.

    Full Text Available Abstract Background The haematological profile of the pregnant woman has an impact on the outcome of the pregnancy. Published guidelines indicate acceptable levels for haematological indices in pregnancy but they are population specific. Indicators of haemoglobin concentration are the most commonly utilized of the indices. These published international norms are used across populations, however, there is no evidence confirming their applicability to a population such as the Jamaican pregnant woman. This study was therefore undertaken with the intent of documenting the haematological profile of pregnant primigravid Jamaican women and comparing these to the established norms to determine whether the norms apply or whether there was a need to establish local norms. Methods This was a longitudinal study done on a cohort of 157 healthy primigravid women ages 15 to 25 and without anaemia, and who were recruited from the antenatal clinic of the University Hospital of the West Indies, Kingston, Jamaica. The haemoglobin concentration, packed cell volume, mean cell volume, mean cell haemoglobin, mean cell haemoglobin concentration, white blood cell count, red blood cell count and platelet count were measured on samples of blood obtained from each consenting participant during each of the three trimesters. The results were analysed using SPSS for windows (Version 11 and the data expressed as means ± S.D. Means were compared using the student's paired t-test. Comparison was then made with the international norms as recommended by the United States Center for Disease Control (1989. Ethical approval for this study was obtained from the University Hospital of the West Indies/University of the West Indies Ethics Committee. Results The results showed changes by trimester in all measured variables. For most of the indices the changes achieved levels of significance across trimesters. These changes were however in keeping with the expected physiological response

    The management of epistaxis requires an understanding of haematological factors that may complicate its treatment. This systematic review includes six distinct reviews examining the evidence supporting epistaxis-specific management strategies relating to warfarin, direct oral anticoagulants, heparin, antiplatelet agents, tranexamic acid and transfusion. A systematic review of the literature was performed using a standardised methodology and search strategy. Limited numbers of articles were identified in each systematic review, with level 1 evidence only regarding the use of tranexamic acid. No studies met the inclusion criteria within the heparin, direct oral anticoagulants or transfusion systematic reviews. Many studies were limited by small sample sizes and significant risk of bias. The management of major bleeding and transfusion practice is well documented in national guidance from multiple sources. The guidelines include advice on anticoagulants, antiplatelet agents and tranexamic acid. In the absence of more specific evidence, these guidelines should be applied in the management of epistaxis.

    In 10 female and eight male Danish elite middle- and long-distance runners, haematological status, including blood volume, was examined. Haemoglobin, haematocrit and serum (s)-ferritin concentrations were all within the normal range. In both men and women, blood volume, plasma volume...... and erythrocyte volume were increased in relation to various reference values. However, the runners had a low body weight due to a reduced fat level, 9.5% (7.3-15.1%) fat for the women, 5.9% (5.0-8.8%) fat (median and ranges) for the men, measured by dual-energy X-ray absorptiometry (DEXA) scanning. When...... the runners' body weights were 'normalized' to a reference population (25% fat for women, 15% fat for men), only plasma volume remained increased in relation to body weight for the women, whereas all the volumes remained increased for the men. This confirms that endurance training induces a true increased...

    To determine the clinico haematological features, treatment and outcome of children diagnosed with aplastic anemia at a single institution. Study Design: Observational study. Place and Duration of Study: The Aga Khan University Hospital, Karachi, from January 1999 till December 2008. Methodology: Medical records of children aged less than 15 years of age diagnosed with aplastic anemia were reviewed. Clinico haematological features, treatment and its response to therapy and outcome were recorded. Results were described in percentages. Results: Ninety patients were diagnosed to have aplastic anemia (AA); 65 were male during the study period. Age ranged from 1 to 15 years. Fever in 65 patients (72.2%), pallor in 53 (58.8%), skin bleeding in 49 (54.4%) and epistaxis in 31(34.4%) were the most common and frequent presenting features. Congenital (Fanconi's) anemia was found in 15 (16.6%) and acquired idiopathic in 75 (83.4%) of patients. Very severe aplastic anemia (VSAA) was seen in 29 (32.2%), 26 (28.9%) had severe AA and 17 (18.9%) had moderate AA. Eight patients (8.9%) underwent haematopoietic stem cell transplantation (HSCT), 12 (13.3%) received immunosuppressive therapy (IST) and 70 patients (77.7%) received other and supportive therapy. Five (62.5%) patients showed complete response to HSCT and 3 (37.5%) failed to engraft. IST showed complete response in 3 (25%), partial response in 5 (41.6%) and no response in 4 (33.3%). Twenty two patients (24.4%) expired either due to infection in 16 (72.7%, fungal in 6, bacterial in 10) and intracranial haemorrhage in 6 (27.3%) cases. Conclusion: Majority of cases with AA were acquired and idiopathic in etiology. VSAA and SAA were frequent. Response to HSCT and IST was sub-optimal. (author)

    340 patients had curative treatment with mantle or paraaortic and pelvic radiotherapy (1964 to 1972) or mantle plus paraaortic and spleen or splenic pedicle or total nodal radiotherapy with or without chemotherapy (1973 to 1992). Since 1987, after chemotherapy only modified involved fields were irradiated. All seconds tumors have been histologically verified. The cumulative incidence of second solid cancer of the patients have been compared with the age and sex specific expected rates according to the ''Zuercher Krebsregister 1980 to 1990''. We observed seven patients with leucemia after radiotherapy plus chemotherapy, five patients with non-Hodgkin-lymphoma and 21 patients with solid cancers after radiotherapy or radiotherapy and chemotherapy with a cumulative risk of all second malignancies of 7,0% (ten years), 30.7% (20 years) and 40,5% (24 years). Cumulative risk of second solid cancer was 3,1% (ten years), 9,3% (15 years), 23,5% (20 years) and 34,3% (24 years). Cumulative risk of second solid cancer was significantly higher than expected with no decrease of the relative risk after more than 20 years of follow-up. We observed a significantly higher risk of breast cancer in women less than 30 years of age at treatment. Relative risk of second solid cancer was higher after radiotherapy plus chemotherapy compared to radiotherapy alone, but the difference was not statistically significant. Nearly all patients with radiotherapy plus chemotherapy and a follow-up of ten years or more had radiotherapy with large fields. (orig./MG) [de

    Full Text Available One hundred (50 males and 50 females B-not strain indigenous turkeys, Meleagris gallopavo, were used to determine the reference values for their haematological parameters. The turkeys were housed in the poultry unit and jugular venepunctures were used to collect their blood. The haematological parameters were determined using standard procedures. The mean values of: the packed cell volume (PCV; 37.29 ± 0.37 %, red blood cell (RBC counts (2.50 ± 0.44 × 106.µl−1, haemoglobin concentration (Hbc; 10.89 ± 0.34 g.dl−1, mean corpuscular volume (MCV; 150.63 ± 0.73 fl, mean corpuscular haemoglobin (MCH; 44.29 ± 1.78 pg, mean corpuscular haemoglobin concentration (MCHC; 29.10 ± 0.73 g.dl−1, and white blood cell (WBC counts (12.41 ± 0.83 × 103 µl−1 were determined. No significant differences were found between the male and female B-not strain turkeys in this study. The results will help in the interpretation of cases of disease when there are variations in the values and serve as baseline data for B-not strain of turkeys in the humid tropics.

    A joint working group established by the Haemato-oncology subgroup of the British Committee for Standards in Haematology (BCSH) and the British Transplantation Society (BTS) has reviewed the available literature and made recommendations for the diagnosis and management of post-transplant lymphoproliferative disorder (PTLD) in adult recipients of solid organ transplants. This review details the risk factors predisposing to development, initial features and diagnosis. It is important that the risk of developing PTLD is considered when using post transplant immunosuppression and that the appropriate investigations are carried out when there are suspicions of the diagnosis. These must include tissue for histology and computed tomography scan to assess the extent of disease. These recommendations have been made primarily for adult patients, there have been some comments made with regard to paediatric practice.

    Approximately 2.8 billion people cook with solid fuels. Research has focused on the health impacts of indoor exposure to fine particulate pollution. Here, for the 2010 Global Burden of Disease project (GBD 2010), we evaluated the impact of household cooking with solid fuels on regional population-weighted ambient PM2.5 (particulate matter ≤ 2.5 μm) pollution (APM2.5). We estimated the proportion and concentrations of APM2.5 attributable to household cooking with solid fuels (PM2.5-cook) for the years 1990, 2005, and 2010 in 170 countries, and associated ill health. We used an energy supply-driven emissions model (GAINS; Greenhouse Gas and Air Pollution Interactions and Synergies) and source-receptor model (TM5-FASST) to estimate the proportion of APM2.5 produced by households and the proportion of household PM2.5 emissions from cooking with solid fuels. We estimated health effects using GBD 2010 data on ill health from APM2.5 exposure. In 2010, household cooking with solid fuels accounted for 12% of APM2.5 globally, varying from 0% of APM2.5 in five higher-income regions to 37% (2.8 μg/m3 of 6.9 μg/m3 total) in southern sub-Saharan Africa. PM2.5-cook constituted > 10% of APM2.5 in seven regions housing 4.4 billion people. South Asia showed the highest regional concentration of APM2.5 from household cooking (8.6 μg/m3). On the basis of GBD 2010, we estimate that exposure to APM2.5 from cooking with solid fuels caused the loss of 370,000 lives and 9.9 million disability-adjusted life years globally in 2010. PM2.5 emissions from household cooking constitute an important portion of APM2.5 concentrations in many places, including India and China. Efforts to improve ambient air quality will be hindered if household cooking conditions are not addressed.

    Haematology and blood transfusion, as a clinical and laboratory discipline, has a far-reaching impact on healthcare both through direct patient care as well as provision of laboratory and transfusion services. Improvement of haematology and blood transfusion may therefore be significant in achieving advances in health in Africa. In 2005, Tanzania had one of the lowest distributions of doctors in the world, estimated at 2·3 doctors per 100 000 of population, with only one haematologist, a medical doctor with postgraduate medical education in haematology and blood transfusion. Here, we describe the establishment and impact of a postgraduate programme centred on Master of Medicine and Master of Science programmes to build the capacity of postgraduate training in haematology and blood transfusion. The programme was delivered through Muhimbili University of Health and Allied Sciences (MUHAS) with partnership from visiting medical and laboratory staff from the UK and complemented by short-term visits of trainees from Tanzania to Haematology Departments in the UK. The programme had a significant impact on the development of human resources in haematology and blood transfusion, successfully training 17 specialists with a significant influence on delivery of health services and research. This experience shows how a self-sustaining, specialist medical education programme can be developed at low cost within Lower and Middle Income Countries (LMICs) to rapidly enhance delivery of capacity to provide specialist services. © 2017 John Wiley & Sons Ltd.

    Objectives The objectives of this study were, first, to report the haematological parameters and coagulation times for cats with a congenital portosystemic shunt (CPSS) and the influence of surgical shunt attenuation on these parameters; and, second, to identify any association between prolongation in coagulation profiles and incidence of perioperative haemorrhage. Methods This was a retrospective clinical study using client-owned cats with a CPSS. Signalment, shunt type (extra- or intrahepatic), degree of shunt attenuation (complete or partial), haematological parameters, prothrombin time (PT) and activated partial thromboplastin time (aPTT) test results, and occurrence of any perioperative clinical bleeding complications were recorded for cats undergoing surgical treatment of a CPSS at the Royal Veterinary College, UK, between 1994 and 2011. Results Forty-two cats were included. Thirty-six (85.7%) had an extrahepatic CPSS and six (14.3%) had an intrahepatic CPSS. Preoperatively, mean cell volume (MCV) and mean cell haemoglobin (MCH) were below the reference interval (RI) in 32 (76.2%) and 31 (73.8%) cats, respectively. Red blood cell count and mean cell haemoglobin concentration (MCHC) were above the RI in 10 (23.8%) and eight (19.1%) cats, respectively. Postoperatively, there were significant increases in haematocrit ( P = 0.044), MCV ( P = 0.008) and MCH ( P = 0.002). Despite the significant increase in MCV postoperatively, the median MCV postoperatively was below the RI, indicating persistence of microcytosis. Preoperatively, PT was above the upper RI in 14 cats (87.5%), and aPTT was above the upper RI in 11 cats (68.8%). No cat demonstrated a perioperative clinical bleeding complication. Conclusions and relevance Cats with a CPSS are likely to present with a microcytosis, but rarely present with anaemia, leukocytosis or thrombocytopenia. Surgical attenuation of the CPSS results in a significant increase in the HCT and MCV. Coagulation profiles in cats with a

    Today, hyperthermia plays a significant role in the evidence-based on treatment of cancer patients. Such promising endeavor is due to the fact that neoplastic cells are more heat sensitive than normal cells. the prospect of using hyperthermia alone to treat cancer tumours is appealing because hyperthermia is a physical treatment and so would have fewer side effects than chemotherapy or radiotherapy and, it could be used in combination with these therapeutic approaches. much more consistent evidence has been obtained experimentally, and continuing clinical interest has been encouraged by confirmation that, at relatively low temperature (37-41.5 C), heat enhances cell growth and may well enhance also the growth and proliferation of tumours, while above 45 C heat begins to damage both normal and malignant cells in both animal and human. So, the goal is to achieve a selective temperature elevation between 42-45 C at the tumour site while maintaining healthy tissue temperatures in a physiological save range.This study was undertaken to investigate the effect of acute whole body hyperthermia , (WBH) (rectal temperature 43 c) on biochemical , hormonal and haematological changes in normal healthy local strain (baladi) rabbits.The thermal late effects (recovery) at 24 hr-post whole body hyperthermia was also undertaken , in the attempt to evaluate the degree of safety , when hyperthermia is applied in the clinic for treating cancer and other diseases

    Full Text Available Abstract Background Candida krusei infections are associated with high mortality. In order to explore ways to prevent these infections, we investigated potential routes for nosocomial spread and possible clonality of C. krusei in a haematological unit which had experienced an unusually high incidence of cases. Methods We searched for C. krusei contamination of the hospital environment and determined the level of colonization in patients and health care workers. We also analyzed the possible association between exposure to prophylactic antifungals or chemotherapeutic agents and occurrence of C. krusei. The C. krusei isolates found were genotyped by pulsed-field electrophoresis method in order to determine possible relatedness of the cases. Results Twelve patients with invasive C. krusei infection and ten patients with potentially significant infection or mucosal colonization were documented within nine months. We were unable to identify any exogenic source of infection or colonization. Genetic analysis of the isolates showed little evidence of clonal transmission of C. krusei strains between the patients. Instead, each patient was colonized or infected by several different closely related genotypes. No association between medications and occurrence of C. krusei was found. Conclusion Little evidence of nosocomial spread of a single C. krusei clone was found. The outbreak may have been controlled by cessation of prophylactic antifungals and by intensifying infection control measures, e.g. hand hygiene and cohorting of the patients, although no clear association with these factors was demonstrated.

    Although people with haematological malignancies have to endure long phases of therapy and immobility which is known to diminish their physical performance level, the advice to rest and avoid intensive exercises is still common practice. This recommendation is partly due to the severe anaemia and thrombocytopenia from which many patients suffer. The inability to perform activities of daily living restricts them, diminishes their quality of life and can influence medical therapy. To evaluate the efficacy, safety and feasibility of aerobic physical exercise for adults suffering from haematological malignancies. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, 2014, Issue 1) and MEDLINE (1950 to January 2014) as well as conference proceedings for randomised controlled trials (RCTs). We included RCTs comparing an aerobic physical exercise intervention, intending to improve the oxygen system, in addition to standard care with standard care only for adults suffering from haematological malignancies. We also included studies that evaluated aerobic exercise in addition to strength training. We excluded studies that investigated the effect of training programmes that were composed of yoga, tai chi chuan, qigong or similar types of exercise. We also excluded studies exploring the influence of strength training without additive aerobic exercise. Additionally, we excluded studies assessing outcomes without any clinical impact. Two review authors independently screened search results, extracted data and assessed the quality of trials. We used risk ratios (RRs) for adverse events and 100-day survival, standardised mean differences for quality of life (QoL), fatigue, and physical performance, and mean differences for anthropometric measurements. Our search strategies identified 1518 potentially relevant references. Of these, we included nine RCTs involving 818 participants. The potential risk of bias in these trials is unclear, due

    A common trend in higher education is the "flipped" classroom, which facilitates active learning during class. The flipped approach to teaching was instituted in a haematology `major' class and the students' attitudes and preferences for the teaching materials were surveyed. The curriculum design was explicit and involved four major components (1) the preparation of the students; (2) the weekly pre-class work; (3) the in-class active learning strategies and (4) closing the learning loop using formative quizzes. Each of these components is discussed in detail and was informed by sound pedagogical strategies. Several different sources of information and several freely available software tools to engage the students are discussed. Two iterations are reported here, with improved pass rate for the final examination from 47 to 48 % in the traditional class to 56-65 % in the flipped classroom approach. The majority of students (93 and 89 %) came to the class prepared, after viewing the screencasts and engaged fully with the activities within the face-to-face time. The students perceived that solving case studies (93 %) was the most beneficial activity for their learning and this was closely followed by the production of essay plans (71 %). The majority of students recommended that this approach be repeated the following year (69 and 75 %).

    Avascular necrosis (AVN) is a serious complication of high-dose chemotherapy for haematological malignancy in childhood. In order to describe its incidence and main risk factors and to evaluate the current treatment options, we reviewed 105 children with a mean age of 8.25 years (1 to 17.8) who had acute lymphoblastic or acute myeloid leukaemia, or a non-Hodgkin's lymphoma. Overall, eight children (7.6%) developed AVN after a mean of 16.8 months (8 to 49). There were four boys and four girls with a mean age of 14.4 years (9.8 to 16.8) and a total of 18 involved sites, 12 of which were in the femoral head. All these children were aged > nine years (p < 0.001). All had received steroid treatment with a mean cumulative dose of prednisone of 5967 mg (4425 to 9599) compared with a mean of 3943 mg (0 to 18 585) for patients without AVN (p = 0.005). No difference existed between genders and no thrombophilic disorders were identified. Their initial treatment included 11 core decompressions and two bipolar hip replacements. Later, two salvage osteotomies were done and three patients (four hips) eventually needed a total joint replacement. We conclude that AVN mostly affects the weight-bearing epiphyses. Its risk increases with age and higher steroid doses. These high-risk patients may benefit from early screening for AVN.

    We report about the development of all-solid-state laser source of narrowband UV-B light for medical applications. The device is based on a gain-switched Ti: Sapphire laser with volume Bragg grating, pumped at 532 nm and operating at 931.8 nm, followed by a third harmonic generator and a fiber optic beam homogenizer. The maximum available pulse energy exceeded 5 mJ at 310.6 nm, with a pulse repetition rates of 50 Hz. The output characteristics satisfy the medical requirements for psoriasis and vitiligo treatment. A new optical scheme for third harmonic generation enhancement at moderate levels of input intensities is proposed and investigated. As a result, 40% harmonic efficiency was obtained, when input pulse power was only 300 kW.

    The development of effective radio protectors and radio recovery drugs is of great importance in view of their potential application during both planned (i.e., radiotherapy) and unplanned radiation exposure (i.e., in the nuclear industry and natural background radiation). The combined effect of radiation and cadmium further increases the causation of damages to organs and tissues. Aloe vera has enjoyed a reputation as a healer for millennia, based primarily on anecdotal evidence. For the last 40 years concerted efforts by the scientific research community has brought Aloe vera out of the realm of folk medicine, providing it solid medical and scientific foundation. Haematopoietic organs are among the most radiosensitive cells in the living organisms. Therefore, present study was carried out to study the modulatory influence of Aloe vera against radiation and cadmium induced hematological changes in the Swiss albino mice. For the study, six to eight weeks old male Swiss albino mice were procured and kept in polypropylene cages.The animals were exposed 3.5 Gy and 7.0 Gy of gamma radiation with or without cadmium chloride treatment. The Aloe vera was administered seven days prior to irradiation or cadmium chloride treatment. Five animals from each group were autopsied by cervical dislocation at each post treatment interval of 1, 2, 4, 7, 14 and 28 days. Blood was collected in heparinized tubes to estimate various haematological parameters viz. RBC, WBC, PCV, Haemoglobin and MCV. Radiation exposure resulted in a significant decline in RBC, WBC, PCV, Haemoglobin and MCV up to day-14 in peripheral blood, thereafter it increased up to day-28 without reaching to normal. After combined treatment of radiation and cadmium chloride the more severe changes were noticed showing synergistic or additive effect. An early and fast recovery was seen in Aloe vera pretreatment groups. Thus, it may be concluded from above observation that Aloe vera has the potential of combating the

    Full Text Available Interleukin (IL-21 is an attractive antitumor agent with potent immunomodulatory functions. Yet thus far, the cytokine has yielded only partial responses in solid cancer patients, and conditions for beneficial IL-21 immunotherapy remain elusive. The current work aims to identify clinically-relevant IL-21 regimens with enhanced efficacy, based on mathematical modeling of long-term antitumor responses. For this purpose, pharmacokinetic (PK and pharmacodynamic (PD data were acquired from a preclinical study applying systemic IL-21 therapy in murine solid cancers. We developed an integrated disease/PK/PD model for the IL-21 anticancer response, and calibrated it using selected "training" data. The accuracy of the model was verified retrospectively under diverse IL-21 treatment settings, by comparing its predictions to independent "validation" data in melanoma and renal cell carcinoma-challenged mice (R(2>0.90. Simulations of the verified model surfaced important therapeutic insights: (1 Fractionating the standard daily regimen (50 µg/dose into a twice daily schedule (25 µg/dose is advantageous, yielding a significantly lower tumor mass (45% decrease; (2 A low-dose (12 µg/day regimen exerts a response similar to that obtained under the 50 µg/day treatment, suggestive of an equally efficacious dose with potentially reduced toxicity. Subsequent experiments in melanoma-bearing mice corroborated both of these predictions with high precision (R(2>0.89, thus validating the model also prospectively in vivo. Thus, the confirmed PK/PD model rationalizes IL-21 therapy, and pinpoints improved clinically-feasible treatment schedules. Our analysis demonstrates the value of employing mathematical modeling and in silico-guided design of solid tumor immunotherapy in the clinic.

    von Hippel Lindau disease (VHL) is an autosomal dominant familial cancer syndrome linked to alteration of the VHL tumor suppressor gene. Affected patients are predisposed to develop pheochromocytomas and cystic and solid tumors of the kidney, CNS, pancreas, retina, and epididymis. However, organ involvement varies considerably among families and has been shown to correlate with the underlying germline alteration. Clinically, we observed a paradoxically lower prevalence of renal cell carcinoma (RCC) in patients with complete germline deletion of VHL. To determine if a relationship existed between the type of VHL deletion and disease, we retrospectively evaluated 123 patients from 55 families with large germline VHL deletions, including 42 intragenic partial deletions and 13 complete VHL deletions, by history and radiographic imaging. Each individual and family was scored for cystic or solid involvement of CNS, pancreas, and kidney, and for pheochromocytoma. Germline deletions were mapped using a combination of fluorescent in situ hybridization (FISH) and quantitative Southern and Southern blot analysis. An age-adjusted comparison demonstrated a higher prevalence of RCC in patients with partial germline VHL deletions relative to complete deletions (48.9 vs. 22.6%, p=0.007). This striking phenotypic dichotomy was not seen for cystic renal lesions or for CNS (p=0.22), pancreas (p=0.72), or pheochromocytoma (p=0.34). Deletion mapping revealed that development of RCC had an even greater correlation with retention of HSPC300 (C3orf10), located within the 30-kb region of chromosome 3p, immediately telomeric to VHL (52.3 vs. 18.9%, p <0.001), suggesting the presence of a neighboring gene or genes critical to the development and maintenance of RCC. Careful correlation of genotypic data with objective phenotypic measures will provide further insight into the mechanisms of tumor formation. Copyright 2003 Wiley-Liss, Inc.

    Standard treatment for inflammatory bowel diseases (IBD) necessitates frequent intake of anti-inflammatory and/or immunosuppressive drugs, leading to significant adverse events. To evaluate the role solid lipid nanoparticles (SLN) play as drug delivery system in enhancing anti-inflammatory activity for drugs such as dexamethasone and butyrate in a human inflammatory bowel diseases whole-blood model. ELISA assay and the peripheral blood mononuclear cell (PBMC) cytokine mRNA expression levels were evaluated by quantitative SYBR Green real-time RT-PCR to determine the IL-1beta, TNF-alpha, IFN-gamma and IL-10 secretion in inflammatory bowel diseases patients' PBMC culture supernatants. There was a significant decrease in IL-1beta (p<0.01) and TNF-alpha (p<0.001) secretion, whilst IL-10 (p<0.05) secretion significantly increased after cholesteryl butyrate administration, compared to that of butyrate alone at the highest concentration tested (100 microM), at 24h exposure. There was a significant decrease in IL-1beta (p<0.01), TNF-alpha (p<0.001) and IL-10 (p<0.001) secretion after dexamethasone loaded SLN administration, compared to dexamethasone alone at the highest concentration tested (250 nM) at 24h exposure. No IFN-gamma was detected under any conditions and no cytotoxic effects observed even at the highest concentration tested. The incorporation of butyrate and dexamethasone into SLN has a significant positive anti-inflammatory effect in the human inflammatory bowel disease whole-blood model. Copyright 2010 Elsevier B.V.

    The objectives of the work were to study the features of experimentally induced canine mastitis and to present hypotheses regarding the pathogenesis of the disease. The right caudal abdominal mammary gland of six bitches was inoculated on day 8 after whelping with Staphylococcus intermedius to induce mastitis; adjacent mammary glands were used as controls. Clinical examination, bacteriological and cytological (whiteside test, Giemsa) examination of mammary secretion, as well as haematological tests were performed from 5 days before until 34 days after challenge. Mastectomy was sequentially performed 1, 2, 4, 18, 26 and 34 days after challenge in each of the bitches, in order to carry out a pathological examination of mammary glands. All animals developed clinical mastitis: challenged glands became painful, hot, enlarged and oedematous; secretion was brownish, purulent, with flakes or clots, subsequently becoming yellowish and thick. Staphylococci were isolated from all inoculated glands (up to 22 days). WST was positive in 41/46 samples from inoculated glands and 66/138 samples from control glands; neutrophils predominated during the acute stage. Blood leukocyte counts increased, whilst platelet counts decreased. Gross pathological findings initially included congestion, purulent discharge and subcutaneous oedema; then abscesses, brownish areas and size decrease were seen. Salient histopathological features were initially neutrophilic infiltration, haemorrhages, destruction of mammary epithelial cells and alveoli, and then infiltration by lymphocytes, shrunken alveoli, loss of glandular architecture and fibrous tissue proliferation. We conclude that in bitches, intrammamary inoculation of Staphylococcus intermedius can induce clinical mastitis, followed by subclinical disease. The disorder is characterized by bacterial isolation and leukocyte influx in challenged glands, by leukocyte presence in adjacent mammary glands, by increased blood leukocyte counts and by

    Full Text Available The aim of the study was to determine the values of selected haematological indices of the Polbar breed of chickens by gender and age. There was a significant WBC difference in cocks and hens with age. In each of the periods, cocks were characterized by a lower than hens number of LY. LY and NE declined with increasing age. Most values showed significant (P ≤ 0.05 differences for birds at different ages. These results of the haematological indices from consolidated Polbar breed can be used for comparisons with other breeds of poultry. The study deepens and organizes the knowledge within the possibilities of using and interpreting levels of haematological indicators for monitoring health of hens. In this paper, we managed to obtain information on the level of indicators rarely determined in chickens.

    The consequences of an ‘all in-all out' static group of uniform age vs. a continuously dynamic group with litter introduction and exit every third week were examined with respect to stress response and haematological parameters in large groups of 60 pigs. The experiment included a total of 480 pigs...... from weaning at the age of 4 weeks to the age of 18 weeks after weaning. Limited differences were found in stress and haematological parameters between pigs in dynamic and static groups. The cortisol response to the stress test was increasing with the duration of the stress test in pigs from...... the dynamic group while it was decreasing in the static group. The health condition and the growth performance were reduced in the dynamic groups compared with the static groups. In the dynamic groups the haematological parameters indicated an activation of the immune system characterised by an increased...

There were differences in haematology and biochemistry profiles between adult dairy cattle and calves, but most of these differences likely had a physiological rather than pathological basis. Overall, the haematological changes in calves aged cattle.

    Pre-analytical handling may be an important determinant of haematological variables, if analysis is delayed. We investigated the effect of anticoagulants, i.e. tripotassium ethylenediamine-tetraacetic acid (EDTA) and citric acid, theophylline, adenosine, dipyridamole (CTAD), storage time (0.5, 1......, the samples must be stored in a refrigerator until analysis. Our studies underline that time delay before analysis of haematological variables can cause increased variation, and should therefore be limited as far as possible in order to reduce the number of animals needed to make reliable conclusions...

    Present study deals with the impact of Gorakhpur distillery effluent at various concentration levels (5, 10 and 20%) on the blood profile of fingerling of, Colisa fosciotus after 30 days of exposure. Observations revealed that 5% of effluent concentration produced no significant alterations in various haematological parameters except for clotting time and immature erythrocytes. However, 10% of effluent concentration brought significant alterations in hematocrit as well as clotting time and 20% of effluent concentration produced highly significant (P<0.001) alteration in most of the haematological parameters except for hemoglobin percentage.

    Haematological cancers differ from other cancers mainly with regard to treatment strategies: surgery is used for diagnostic purposes but rarely for treatment, whereas chemotherapy is of central importance and, in some cases, cures patients. This article reviews studies that examine the relationships between psychosocial factors and quality of life (QoL) in haematological cancer patients. A review of the literature was conducted from the databases 'PsycInfo', 'Medline' and 'Science Direct' using the keywords 'lymphoma', 'leukaemia', 'myeloma', 'quality of life', 'psychosocial factors', 'coping', 'social support', 'personality', 'anxiety,' 'depression', 'locus of control' and 'alexithymia'. Fourteen studies were analysed. One study found positive relationships between sense of coherence and health-related QoL, whereas another showed a positive link between self-esteem and QoL. Another study suggested that a high external health locus of control was related to a better QoL. Fighting spirit had a positive impact on QoL for two studies, and helplessness-hopelessness was positively related to emotional distress in one study. Two studies indicated the relationships between emotional distress and QoL. Satisfaction with information about disease determined emotional distress in another study. Social support, general health perceptions, global meaning or spirituality were found to improve QoL in four other reports. Literature about the relationships between psychosocial factors and QoL is lacking. Sense of coherence, self-esteem and health locus of control, coping strategies, social support, global meaning or emotional distress are associated with QoL. Results concerning coping and social support should be interpreted with caution because of level II evidence in studies. Copyright © 2012 John Wiley & Sons, Ltd.

    Full Text Available Introduction & Objective: Fascioliasis is a zoonotic parasitic disease, caused by the liver fluke, Fasciola spp.. Human is occasional host when ingesting the metacercaria by eating contaminated aquatic vegetable. In the two past decades, human fasciolasis was emerging as a problem of public health in the Guilan province; in Anzali city. Triclabendazole is a novel anti-helmenthic that during recent years has been used for fascioliasis treatment in this region. The aim of the present work is to study alteration in haematological and liver function indices during human infection with Fasciola spp. pre and post treatment with triclabendazoleMaterials & Methods: The present work is a longitudinal clinical trail. In this regard, fifty confirmed fasciolasis patients, were chosen for parasitological, hematological and biochemical examinations pre-therapy as well as 1 and 6 months post-therapy. Formalin-ether and modified Telemann methods were used for stool examination. For Fasciola antibody detection ELISA technique was employed. Hematological and biochemical tests were performed by standard methods. Results: Results indicated that, triclabendazole efficacy was 74% after usage as one dose of 20mg/kg and reached to 88% after repeating in the next month. Before triclabebdazole therapy the Hb and HCT of the patients were slightly found lower than normal ranges, meanwhile the ESR and eosinophil percentages were higher. However following receiving the drug, in the cured individuals, the indices returned to the normal ranges but in the non-cured individuals were not shifted to the normal. On the other hand liver function indices of the patients mostly were at normal ranges before and following drug therapy.Conclusion: In conclusion haematological indices could be valuable indicator for successful therapy of patients treated with triclabendazole.

    Full Text Available The use of simple and economic tests to rule out diseases of sufficient clinical severity is appealing in emergency department (ED, since it would be effective for contrasting ED overcrowding and decreasing healthcare costs. The aim of this study was to assess the diagnostic performance of simple and economic haematological testing in a large sample of adult patients presenting at the ED of the Academic Hospital of Parma during the year 2010 with the five most frequent acute pathologies (i.e., acute myocardial infarction, renal colic, pneumonia, trauma and pancreatitis. Both leukocyte count and hemoglobin showed a good diagnostic performance (Area Under the Curve [AUC] of 0.85 for leukocyte count and 0.76 for hemoglobin; both p < 0.01. Although the platelet count was significantly increased in all patients groups except pancreatitis, the diagnostic performance did not achieve statistical significance (AUC 0.53; p = 0.07. We also observed an increased RDW in all groups, except in those with trauma and the diagnostic performance was acceptable (AUC 0.705; p < 0.01. The mean platelet volume (MPV was consistently lower in all patients groups and also characterized by an efficient diagnostic performance (AUC 0.76; p < 0.01. This evidence led us to design an arbitrary formula, whereby MPV and hemoglobin were multiplied, and further divided by the leukocyte count, obtaining a remarkable AUC (0.91; p < 0.01. We conclude that simple, rapid and cheap hematological tests might provide relevant clinical information for decision making to busy emergency physicians, and the their combination into an arbitrary formula might further increase the specific diagnostic potential of each of them.

    A haematological malignancy is a serious, life-altering disease and may be characterised as an uncontrollable and unpredictable stress situation. In dealing with potentially threatening information, individuals generally utilise two main cognitive coping styles: monitoring (the tendency to seek threat-relevant information) and blunting (avoiding threatening information and seeking distraction). The aim of this study was to obtain insight into the association between cognitive coping style and (a) need for information, (b) satisfaction with information, (c) involvement in decision making, and (d) quality of life (QoL). In this cross-sectional study, coping style was assessed among adult patients diagnosed with a haematological malignancy, using an adapted version of the Threatening Medical Situations Inventory. Information need, information satisfaction, decision-making preference and QoL were measured with validated questionnaires. In total, 458 patients returned the questionnaire (66%). A monitoring coping style was positively related to need for both general and specific information. Blunting was positively and QoL was negatively related to need for information. Monitoring was positively related to involvement in decision-making and negatively to information satisfaction. Using multivariate analysis, this relation between monitoring and information satisfaction disappeared, and for blunting, we found a negatively significant relation. QoL was not related to coping style. Among patients with haematological malignancies, coping style is related to a need for information, information satisfaction, and involvement in treatment decision-making. Therefore, it is important for health care professionals to be aware of individual differences in cognitive coping style. Copyright © 2014 John Wiley & Sons, Ltd.

  15. Haematological and biochemical reference intervals for free-ranging brown bears (Ursus arctos) in Sweden

    2014-01-01

    Background Establishment of haematological and biochemical reference intervals is important to assess health of animals on individual and population level. Reference intervals for 13 haematological and 34 biochemical variables were established based on 88 apparently healthy free-ranging brown bears (39 males and 49 females) in Sweden. The animals were chemically immobilised by darting from a helicopter with a combination of medetomidine, tiletamine and zolazepam in April and May 2006–2012 in the county of Dalarna, Sweden. Venous blood samples were collected during anaesthesia for radio collaring and marking for ecological studies. For each of the variables, the reference interval was described based on the 95% confidence interval, and differences due to host characteristics sex and age were included if detected. To our knowledge, this is the first report of reference intervals for free-ranging brown bears in Sweden. Results The following variables were not affected by host characteristics: red blood cell, white blood cell, monocyte and platelet count, alanine transaminase, amylase, bilirubin, free fatty acids, glucose, calcium, chloride, potassium, and cortisol. Age differences were seen for the majority of the haematological variables, whereas sex influenced only mean corpuscular haemoglobin concentration, aspartate aminotransferase, lipase, lactate dehydrogenase, β-globulin, bile acids, triglycerides and sodium. Conclusions The biochemical and haematological reference intervals provided and the differences due to host factors age and gender can be useful for evaluation of health status in free-ranging European brown bears.

    Onco-haematological patients are prone to develop infections, and antibiotic prophylaxis may lead to negative blood cultures. Thus, the microbiological diagnosis and subsequent administration of a targeted antimicrobial therapy is often difficult. The goal of this study was to evaluate the usefulness of IRIDICA (PCR/ESI-MS technology) for the molecular diagnosis of bloodstream infections in this patient group. A total of 463 whole blood specimens from different sepsis episodes in 429 patients were analysed using the PCR/ESI-MS platform, comparing the results with those of blood culture and other clinically relevant information. The sensitivity of PCR/ESI-MS by specimen (excluding polymicrobial infections, n = 25) in comparison with blood culture was 64.3% overall, 69.0% in oncological patients, and 59.3% in haematological patients. When comparing with a clinical infection criterion, overall sensitivity rose to 74.7%, being higher in oncological patients (80.0%) than in haematological patients (67.7%). Thirty-one microorganisms isolated by culture were not detected by IRIDICA, whereas 42 clinically relevant pathogens not isolated by culture were detected moleculary. PCR/ESI-MS offers a reliable identification of pathogens directly from whole blood. While additional studies are needed to confirm our findings, the system showed a lower sensitivity in onco-haematological patients in comparison with previously reported results in patients from the Intensive Care Unit.

    In the long-term biomonitoring of wild populations inhabiting polluted areas, the use of non-destructive biomarkers as markers of condition is very important. We examined the possible effects of metal pollution on the haematological status of adult great tits (Parus major) along a well-established pollution gradient near a non-ferrous smelter in Belgium. We measured blood and feather metal concentrations and assessed the haematological status (amount of red blood cells, haemoglobin concentration, haematocrit, mean corpuscular volume and mean corpuscular haemoglobin) of adult great tits during winter at four study sites. Metal concentrations in blood and feathers indicated that cadmium and lead were the most important metals in the pollution gradient under study. Measurements of haematological parameters revealed that haemoglobin concentration, haematocrit, mean corpuscular volume and mean corpuscular haemoglobin were lower in great tits from the more polluted sites. These parameters were significantly negatively correlated with blood lead concentration. The amount of red blood cells, however, did not significantly differ among study sites. Our results indicate that the haematological status of great tits is negatively affected by metal pollution and may therefore be used as a successful biomarker for monitoring the negative impact of metal exposure in the wild.

    To establish reference haematological values (complete blood count) in healthy full-term newborns of Karachi. This is a cross sectional study design based on cord blood sample of 404 newborns and their mothers recruited from Sindh Government Qatar Hospital, Ziauddin University Hospital gole market campus, Sindh Government hospital, Liaquatabad and Chinniot maternity and child hospital. Karachi from July 2006 to April 2008. Both mother's and the new born baby's blood was collected in EDTA containing tubes and analyzed for different haematological parameters. The data entry and analysis was done on computer package SPSS (Statistical Packages of Social Sciences) version 12.0. The results were given in the text as mean, standard deviation and 95% confidence intervals of haematological values (complete blood count). The mean haemoglobin was found to be (14.99 +/- 1.47 gm), which is lower than the standard value described in literature. However the total WBCs count and platelet count were found to be (13.61 +/- 4.23) and (256. 25 +/- 76.54) respectively, which were similar to the other studies. Our values provide reference range for haematological values in healthy newborns of Karachi, for clinical use by our physicians.

    To explore: (1) how haematological cancer survivors and their support persons perceive the overall performance of the support person; (2) disagreement between survivor and support person ratings; and (3) characteristics associated with support persons rating their performance poorly. This is a substudy of a larger project of Australian haematological cancer survivors and their support persons. For this substudy, haematological cancer survivors were recruited from 4 Australian population-based cancer registries and asked to pass on a questionnaire package to their support persons. Survivors who passed on a questionnaire package to their support person were asked to answer questions about the support person and how they perceived the support person's performance. Similarly, support persons answered questions on their own performance as a support person. A total of 924 haematological cancer survivors and 821 support persons were eligible for this study. Most survivors rated their support person as performing very well (84%) while less than half (48%) of support persons rated their own performance as very well. There was significant disagreement between survivor and their support person (dyad) ratings of the support person's performance. Support persons with above normal levels of depression (vs those with normal levels) had significantly higher odds of rating their own performance as "not well/somewhat well." Health care providers should consider providing additional education and skills-based interventions to support persons who experience increased symptoms of depression.

    To determine the relationship between major depressive disorder, anxiety disorders and the quality of life of haematological cancer patients. This cross-sectional study was conducted at Ampang Hospital Kuala Lumpur, Malaysia, a tertiary referral centre hospital for haematological cancer. The Mini-International Neuropsychiatric Interview was used for the diagnosis of major depressive disorder and anxiety disorders. The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire was utilised to measure patients' quality of life. A total of 105 haematological cancer patients were included in the study with response rate of 100%. Major depressive disorder correlated with almost all domains of the quality of life, except the pain scores. Logistic regression showed that insomnia and financial difficulties were related to major depressive disorder. Different anxiety disorders also correlated with quality of life in specific domains. The leading anxiety disorders that correlated mostly with quality-of-life scales were generalised anxiety disorder, followed by obsessive-compulsive disorder, social anxiety disorder, as well as post-traumatic stress disorder and panic disorder with agoraphobia (p<0.05). Psychological treatment along with medication and intervention should be implemented to improve the overall quality of life and psychiatric disorder symptoms among the haematological cancer patients.

    There are studies that declare blood recovered with the autotransfusion system that is potentially heparinised and mixed with other drugs, can cause haematological alterations in the patient, according to existing evidence. The proposal was to compare the haematological values of the patients before reinfusing red blood cells from the cell saver and 12h after reinfusion. Observational analytical study of 479 patients who underwent cardiac surgery where the cell saver was used. Haematological variables were collected before reinfusion and 12h after reinfusion. Statistically significant haematological values before reinfusion and 12h after reinfusion were: haemoglobin (9.5 to 12.5g/dL), haematocrit (26 to 38%), platelets (214.2 to 164.210^3/μL), total proteins (7.6 to 5.1g/dL), PCR (8.5 to 22.1mg/L) and D-dimer (493.3 to 875.5μg/L) with P<.05. With the use of the cell saver an increase was observed of haemoglobin, haematocrit, PCR and D-dimer values together with a decrease in platelet and total protein numbers.

    Objective: To assess magnitude of tuberculosis (TB) in patients suffering from various haematological malignancies and stem cell transplant (SCT) recipients. Patients and Methods: Patients suffering from various haematological malignancies treated between July 2001 and December 2002 were included in the study. The hospital records and out-patient follow-up charts were reviewed for demographic information, diagnosis, clinical presentation, laboratory investigations, radiological and pathological examinations, sites involved in TB, methods of diagnosis, number and type of anti-tuberculosis drugs given and response to treatment. Results: During the study period a total of 213 (including 25 allogeneic stem cell transplant (SCT) recipients) patients with different haematological disorders were treated. Out of these, 34, including 4 SCT recipients developed tuberculosis. Overall frequency of TB was 16 %. Median age of TB patients was 33.5 years (range 8-80 years). Median time between diagnosis of haematological disorders and tuberculosis was 21 weeks. Sites of involvement by TB were lung (18), disseminated (6), lymph node (5), pleura (2), spine (2) and pericardium (1). Three of the patients died of TB; one undiagnosed, second with multi-drug resistant TB and the third soon after the start of anti-tuberculosis treatment while remaining 31 cases responded to anti-tuberculosis treatment. Conclusion: Tuberculosis is a major problem in immunocompromised patients and there is need to establish guidelines for TB chemoprophylaxis in our setup. (author)

    Full Text Available Aglepristone is a safe abortifacient in cats, dogs and rabbits. Although no serious side effects have been reported, there is no information available about the effects of the medicine on haematological parameters. For the first time clinical and ultrasonographic features and haematological profiles were evaluated in rabbits treated with aglepristone 15 and 16 days after mating. Ten healthy 10–14 month-old New Zealand White female rabbits were mated with fertile bucks and pregnancies were confirmed by ultrasound 15 days later. Of these, 5 does were treated with aglepristone (test group, n = 5 whilst the remaining five (control group, n = 5 were treated with a saline solution (0.9% NaCl. The treatment dose was 10 mg⁄kg body weight, administered subcutaneously once daily on two consecutive days (day 15 and 16 post mating. Ultrasonographic, clinical and haematological assessments were performed daily. Aglepristone treatment induced embryonic fluid resorptions without foetal death in mid-gestation terminations. Following ultrasonographic and haematological examinations, it was established that aglepristone is a safe abortifacient in rabbits.

    Full Text Available Haematological analyses has been routinely used in determining the physiological state of animals and known to be affected by different environmental factors, the present study was therefore designed to assess the effect of 24 hours of light (00D: 24L, 24 hours of darkness (24D: 00L and 12 hour light / 12 hours darkness (12D: 12L photoperiod on the haematological parameters of the African Catfish. At the end of the six weeks experiment, it was observed that some haematological parameters such as Mean Corpuscular Haemoglobin Concentration (MCHC, the Mean White Blood Cells (WBC, Mean Red Blood Cells (RBC, Haemoglobin content (HGB, Platelet count (PLT showed significant difference (P0.05. However MCHC and MCH were noticed to increase as the light period increased while the other parameters reduced as the light period increased. The findings indicate that exposure of the African Catfish to continuous light for six weeks duration elicits response in the haematological profile of the fish.

    The incidence of haematological malignancies in Africa's rapidly urbanising populations is insufficiently explored. Reliable population-based cancer statistics, however, continues to be a scarce resource in Africa and tends to be urban biased with limited rural coverage. In addition, many haematological malignancies are regarded as rare cancers, a sub-group that often affects the young disproportionately and require advanced diagnostic services and facilities able to deliver costly sophisticated treatments. This study provides a first attempt to estimate the incidence of haematological malignancies among the Eastern Cape Province population of South Africa. Multiple public- and private sector data archives and resources were utilised to optimise the identification of incident cases, including clinical records; bone marrow; cytology; histology; flow cytometry and cytogenetic records. Crude incidence, age-and gender-standardised rates are presented and comparison made with existing national data and select data from other economically developed countries and global institutions. A total of 3603 incident cases were identified between 2004 and 2013. Mature lymphoid malignancies accounted for approximately 60% (n = 2153), myeloma/plasma cell neoplasms 13% (n = 465), acute leukaemia 17% (n = 596), chronic myeloid leukaemia 4% (n = 155) and other myeloproliferative neoplasms 6% (n = 234) when stratified according to conventional groups. Most subtypes increase with age, with male excess. Haematological malignancies in the Eastern Cape Province show disparities in gender and pathology-specific incidence patterns. The present study suggest that haematological malignancies are not uncommon in this region and the incidence rate of at least one rare subtype, APL, is comparable with some European populations.

    Objective: To report the initial data on allogeneic peripheral blood stem cell transplantation for haematogical malignancies in Pakistan. Patients and Methods: Patients with haematological malignancies were included who had received allogeneic PBSC transplantation of Filgrastim (rhG-CSF) mobilized peripheral blood stem cells from HLA-identical siblings (except one 5/6 antigen sibling) with Busulphan and Cyclophosphamide standard conditioning therapy in all patients. No patient received antibiotics for gut decontamination. Empirical antibiotics included Ceftriaxone and Amikacin for febrile neutropenia, oral Itraconazole for antifungal prophylaxis while oral acyclovir was used for antiviral prophylaxis. All donors and recipients were CMV IgG positive Cyclosporin A / Methotrexate were given for graft versus host disease (GvHD) prophylaxis. Stem cells were harvested using Haemonetics MCS+ cell separator. All patients received G-CSF starting from day +4 until their neutrophil count rose to normal. Results: There were 21 patients with age range of 8-38 years and male to female ratio of 2:1. Engraftment was achieved in all patients; median time to absolute neutrophil count of > 0.5 x 10/sup 9/I was 10 days (range 8 -12 days) and platelet count of > 20 x 10/sup 9/1 was 14 days (12-17 days). Acute graft versus host disease (aGvHD) was seen in 7 patients; one patient had grade IV skin and hepatic GvHD; another patient had grade III gut GvHD, grade II GvHD was seen in 3 patients while grade I skin aGvHD was seen in 2 patients. Median hospital stay was 34 days. Treatment related mortality was seen in 3 patients (18%). Chronic GvHD was seen in 5 patients. Four more patients died during the follow-up period. Malaria was seen in 2 while tuberculosis developed in one case. Relapse was seen in 2 patients. The estimated probability of survival at one hundred day, at one year and five years was 82, 47 and 40 percent respectively. Conclusion: Haematopoietic stem cell transplant

    A solid-phase radioimmunoassay for the measurement of circulating antibody titres to wheat gliadin is described. Using this assay, the authors have measured antibody titres to unfractionated gliadin in normal healthy controls, in coeliac patients on a gluten-free or a normal diet, and in patients with ulcerative colitis and Crohn's disease. High titres of antibodies to unfractionated gliadin were observed only in the patients with untreated coeliac disease. Antibody titres to α, #betta#, #betta# and #betta# gliadin subfractions were measured in patients with untreated coeliac disease and compared with titres in normal controls. Patients with untreated coeliac disease had higher antibody titres to the gliadin subfractions. No specific pattern of circulating antibody titres to gliadin subfractions was observed in the untreated coeliac patients which would provide a diagnostic profile. These results suggest shared antigenicity between the gliadin subfractions. (Auth.)

    Background Reference intervals for venous blood parameters differs with age, gender, geographic region, and ethnic groups. Hence local laboratory reference intervals are important to improve the diagnostic accuracy of health assessments and diseases. However, there have been no comprehensive published reference intervals established in Oman, the Gulf Cooperation Council or Middle Eastern countries. Hence, the aim of this study was to establish reference intervals for full blood count in healthy Omani adults. Methods Venous blood specimens were collected from 2202 healthy individuals aged 18 to 69 years from January 2012 to April 2017, and analysed by Sysmex XS-1000i and Cell-Dyn Sapphire automated haematology analysers. Results were statistically analysed and compared by gender, age, and ABO blood group. The lower and upper reference limits of the haematology reference intervals were established at the 2.5th and 97.5th percentiles respectively. Results Reference intervals were calculated for 17 haematology parameters which included red blood cell, white blood cell, and platelet parameters. Red blood cell (RBC), haemoglobin (HGB), haematocrit (HCT), platelet and platelet haematocrit counts of the healthy donors were significantly different between males and females at all ages (p values of RBC, HGB and HCT than females. Other complete blood count parameters showed no significant differences between genders, age groups, instruments, or blood groups. Our study showed a lower haemoglobin limit for the normal reference interval in males and females than the currently used in Oman. Conclusions Data from this study established specific reference intervals which could be considered for general use in Oman. The differences in haematology reference intervals highlights the necessity to establish reference intervals for venous blood parameters among the healthy population in each country or at least in each region.

    Full Text Available Wild Nile crocodiles (Crocodylus niloticus of various size classes were captured in the Okavango Delta, Botswana. Blood was collected from the post occipital sinus and used for the determination of a wide range of haematological and biochemical parameters. These values were compared between the sexes and between 3 size classes. The values were also compared with the limited data available from farmed Nile crocodiles, as well as from other wild Nile crocodiles. The Okavango crocodiles were comparatively anaemic, and had comparatively low total protein and blood glucose levels. There was a high prevalence of Hepatozoon pettiti infection, however, there was no significant difference in haematological values between the infected and uninfected crocodiles. The values reported here will be useful in diagnostic investigations in both zoo and farmed Nile crocodiles.

    Evaluation of haematological indicators is carried out as routing in medical surveillance of workers exposed to ionizing radiation, in order to assest the initial and continuing fitness for their intended tasks. The purpose of this work is to analize the behaviour of haematological parametsrs in relation with the time of exposure as well as received doses for workers. It was stabilished a 8 years follw up for the 74 workers of the radiotherapy service in the Oncological Hospital in Havana City. As result were observed no significant changes on mean number of leucocytes, platelets an haemoglobin, which oscillate within normal limits stablished for adult people. Allthought it was incountered an increase in the number of cases with leucopenia, in direct relation with the increase of time of exposure an cumulative doses. The incidence of those cases was 2,3 times higher in the 8th year of the follow up, in relation with the begining of the exposition to ionizing radiation

    In the course of haematological and biological investigations among Aymara and Quechua populations in Bolivia, an anthropological study of the erythrocytary respiratory function was carried out on the two groups at two altitudes: 3,600 m and 450 m. A difference in the intensity of the biological variations of the two populations is observed at high altitude. In the Quechuas, as in any lowland native, the adaptative phenomena are totally and quickly reversible. In the Aymaras, we detected the existence of more marked haematological and biochemical characters: moderate polycythemia, hyperhaemoglobinemia, microcytosis, metabolical hyperactivity with accumulation of 2-3 di-phosphoglycerate and ATP, and methaemoglobinemia with a drop in the activity of the methaemoglobin reductases. The Aymaras preserve some of those characters (methaemoglobinemia excepted) when they settle in lowlands.

    Equine piroplasmosis in donkeys has been recognised as a serious problem of major economic importance. The present molecular study is the first investigation of the presence of Theileria equi and Babesia caballi in Balkan donkeys and of the possible haematological alterations related to it. A total of 70 apparently healthy donkeys from Serbia were included in this study. The overall prevalence of T. equi infection in donkeys tested with multiplex PCR was 50%. There was no B. caballi-positive sample. Infections in donkeys included in this study seem to be associated with decreased red blood cell count, haemoglobin concentration, haematocrit and platelet count, and with increased white blood cell count, mean corpuscular haemoglobin and mean corpuscular haemoglobin concentration. Altered haematological parameters in donkeys can lead to a decrease in working capacity and production performance. Further molecular research and long-term monitoring of equine piroplasmosis is needed in Serbia and throughout Europe.

    1999-04-01

    The effects of the Ginseng extract on various biochemical and haematological parameters in male Wistar rats subjected to a treadmill exercise protocol were studied for 12 weeks. The results showed increases in the haematological parameters, these increases being greatest for the animals treated with the extract during the third month of the study. The exercise also led to increases in these parameters, while the combination of both exercise and extract produced smaller increases. This study shows a clear physiological response due to the ginseng extract administration that reproduces many of the effects obtained after long-term exercise. The combination of exercise and treatments seems to support the theory that there is no clear synergic effect when the advantages associated with the ingestion of ginseng are compared with the performance of exercise.

    2002-01-01

    The impact of the current nursing shortage on the health care system is receiving attention by both state and federal governments. This study, using a convenience sample of 243 oncology/haematology nurses working in 11 Queensland health care facilities, explored factors that influence the quality of nurses' working lives. Although nurses reported high levels of personal satisfaction and personal accomplishment, results indicated that nearly 40% of registered nurses (RNs) are dealing with workloads they perceive excessive, 48% are dissatisfied regarding pay, and professional support is an issue. Furthermore, emotional exhaustion is a very real concern: over 70% of the sample experienced moderate to high levels. Over 48% of the sample could not commit to remaining in the specialty for a further 12 months. Health care managers and governments should implement strategies that can increase nurses' job satisfaction and reduce burnout, thereby enhancing the retention of oncology/haematology nurses.

    Established in 1923, the Thorndike Memorial Laboratory at Boston City Hospital was the first clinical research laboratory in a municipal hospital in the United States of America. Minot and Castle, who were the second and third directors of the Laboratory, were pioneer haematologists and clinical investigators of the highest calibre who created an atmosphere at the Laboratory that would foster patient-centred research and attract the best physician-scientists to work and train there. The haematology research division of the Laboratory made important original contributions to the understanding of the pathophysiology of anaemia, the mechanisms of red cell and platelet destruction and the phagocytic role of the spleen, the nature of haemoglobin (normal and sickle cell), the nature of haemophilia and its therapy and the early classification of lymphoma. It contributed to the Thorndike Memorial Laboratory's worldwide reputation as a model research laboratory and established its reputation as the birthplace of modern haematology.

    Archived patient samples of biological material coupled to clinical databases are valuable and hold the potential to improve patient care, quality control, research and development. Biobanks form a catalytic infrastructure which ensures the registration, handling and storage of collected biological material. Here, we describe the Haematology Biobank and stress the significance of a registration database. Together, these form the basis for retrospective validation of clinical progress and prognostic evaluation of new diagnostic methods, which can therefore be more quickly implemented in the clinic.

    Full Text Available The development of selected haematological and biochemical parameters during the laying period was monitored in common pheasant hens housed in an enhanced cage system. The cages were enhanced by the addition of two perches and a shelter formed by strips of cloth hanging in the corner of the cage. The results showed significant changes in the haematological and biochemical parameters monitored during egg laying. At the time when laying capacity approached a maximum, a decrease was observed (P<0.05 in haematocrit, erythrocytes, and haemoglobin values, whereas monocytes, eosinophils, the heterophil/lymphocyte ratio, phosphorus, and calcium exhibited an increase (P<0.05. At the end of the laying period, an increase (P<0.05 was recorded in the count of leukocytes, heterophils, lymphocytes and basophils, the heterophil to lymphocyte ratio, and the concentrations of aspartate aminotransferase, cholesterol, phosphorus, and calcium, whereas lower values (P<0.05 were recorded for haematocrit and plasma total protein in comparison with the values of the indicators at the beginning of the laying period. The results provide new information about dynamic changes in selected haematological and biochemical parameters in clinically healthy common pheasant hens during the laying period.

    Typhoid fever can involve various organs, leading to a wide range of presentations: from uncomplicated to complicated typhoid fever. The haematological changes are common in typhoid fever and include anaemia, leucopaenia, thrombocytopaenia and bleeding diathesis. This study was undertaken in order to determine the clinical and haematological presentation of typhoid fever in children. In this study, records of children and adolescents with typhoid fever aged under or equal to 16 years, admitted to Yuzuncu Yil University Hospital between 2010 and 2014, were analysed retrospectively. The cases (56%) were admitted to our hospital in July and October. Major symptoms of patients were abdominal pain (24%), arthralgia (21%) and fever (11%). In our study, decreased mean platelet volume (31%), eosinopaenia 20%), abnormal platelet count (19%), anaemia (16%), leucocytosis (16%) and eosinophilia (12%) were the most common haematological findings in the children. Typhoid fever is predominant in children at school age with a slight male predominance. Decreased mean platelet volume and abdominal pain might be useful as early diagnostic clues.

    The impact of altitude training on haematological parameters and the Athlete Biological Passport (ABP) was evaluated in international-level elite athletes. One group of swimmers lived high and trained high (LHTH, n = 10) for three to four weeks at 2130 m or higher whereas a control group (n = 10) completed a three-week training camp at sea-level. Haematological parameters were determined weekly three times before and four times after the training camps. ABP thresholds for haemoglobin concentration ([Hb]), reticulocyte percentage (RET%), OFF score and the abnormal blood profile score (ABPS) were calculated using the Bayesian model. After altitude training, six swimmers exceeded the 99% ABP thresholds: two swimmers exceeded the OFF score thresholds at day +7; one swimmer exceeded the OFF score threshold at day +28; one swimmer exceeded the threshold for RET% at day +14; and one swimmer surpassed the ABPS threshold at day +14. In the control group, no values exceeded the individual ABP reference range. In conclusion, LHTH induces haematological changes in Olympic-level elite athletes which can exceed the individually generated references in the ABP. Training at altitude should be considered a confounding factor for ABP interpretation for up to four weeks after altitude exposure but does not consistently cause abnormal values in the ABP.

    The Present study was designed to study the effect of exposure to electromagnetic field (EMF), emitted from a cellular tower for mobile phone on some biochemical and haematological parameters in male albino rats and to evaluate of the possible protective role of the antioxidant glutathione enhancer on the studied parameters. Three groups of rats were studied, the control (unexposed), the exposed and the treated exposed groups. Exposed groups were subjected to EMF at frequency of 900 MHz, with a peak power of about 60 W, power density of 0.05 mW/ cm"2 at the site of exposure for 24 h/ day for 8 weeks, at the same time treated group was supplied with oral injection of glutathione enhancer three times weekly. At the end of experiment, serum levels of thyroid stimulating hormone (TSH), calcium (Ca), uric acid, malondialdehyde (MDA) beside, the activity of lactate dehydrogenase (LDH) were measured also, some haematological parameters were estimated. Impairment of TSH and serum calcium was expressed by a decrease in serum levels of the exposed group. Meanwhile, serum level of MDA, uric acid and the activity of LDH were increased by exposure. The haematological studies revealed that, exposure to electromagnetic spectrum induced significant reduction in red blood cell counts (RBC's), and haemoglobin concentration (Hb), meanwhile reticulocyte count (Ret) was elevated. The leucocyte counts (WBC's) and platelets count were not affected by exposure. The study demonstrated that glutathione enhancer can attenuate the side effects of exposure to electromagnetic field.

    In this study, effect of ellagic acid on some haematological, immunological and antioxidant parameters in the blood and various tissues of rainbow trout (Oncorhynchus mykiss) were examined. Four groups of rainbow trout were fed experimental diets containing either no ellagic acid (control) or supplemented with ellagic acid at 50 mg/kg diet (EA-50), 100 mg/kg diet (EA-100) or 150 mg/kg diet (EA-150) for 21 days. Samples of the blood and tissue (liver, kidney and spleen) were collected at the end of the experiment and analysed for their haematological profile (the red blood cell count, the haemoglobin concentration and the haematocrit level), immune response (the white blood cell count, the oxidative radical production (NBT activity), the total plasma protein and total immunoglobulin level) and oxidant/antioxidant status (the malondialdehyde level, the superoxide dismutase, catalase and glutathione peroxidase activity as well as the reduced glutathione concentration). The findings of this study demonstrated that ellagic acid had a positive effect on the haematological parameters, the immune response and the antioxidant enzyme activities of the fish.

    Full Text Available Paediatric patients with cancer are a high-risk patient population for medication misadventures. This study aimed to document and evaluate the role of pharmacists’ interventions during dispensing-related activities in minimising the occurrence of medication misadventure in haematology-oncology patients. The primary investigator observed and documented all clinical interventions during dispensing-related activities performed by clinical pharmacists in a haematology-oncology pharmacy during 33-day. A total of 359 interventions were performed for 1028 patients. The rates of intervention were 20.04 per 100 medication orders and 34.92 per 100 patients. Provision of drug information was the most common interventions constituting more than three quarters of all interventions. According to therapeutic groups, cytotoxic antineoplastics made up more than half of all interventions. Of all interventions, 22 involved recommendations leading to changes in patients’ treatment (active interventions, and all recommendations were accepted. The top three medication errors were due to inappropriate dosing, labelling error, and unfulfilled indication. Clinical pharmacists’ intervention during dispensing in a paediatric haematology-oncology pharmacy improved medication safety and patient care by minimising the incidence of medication misadventures.

    Allogeneic haematopoietic stem cell transplantation (HSCT) is the only curative option for patients with Diamond Blackfan anaemia (DBA). We report the transplantation outcome of 30 Italian DBA patients referred to the Italian Association of Paediatric Haematology and Oncology Registry between 1990 and 2012. This is one of the largest national registry cohorts of transplanted DBA patients. Most patients (83%) were allografted after 2000. A matched sibling donor was employed in 16 patients (53%), the remaining 14 patients (47%) were transplanted from matched unrelated donors. Twenty-eight of the 30 patients engrafted. One patient died at day +6 due to veno-occlusive disease without achieving neutrophil recovery and another patient remained transfusion-dependent despite the presence of a full donor chimerism. The 5-year overall survival and transplant-related mortality was 74·4% and 25·6%, respectively. Patients younger than 10 years as well as those transplanted after 2000 showed a significantly higher overall survival and a significantly lower risk of transplant-related mortality. No difference between donor type was observed. Our data suggest that allogeneic HSCT from a related or unrelated donor was a reasonable alternative to transfusion therapy in young and well chelated DBA patients. © 2014 John Wiley & Sons Ltd.

    Post transplant lymphoproliferative disease (PTLD) is a severe complication after solid organ or bone marrow transplantation. In pediatric transplant recipients PTLD is the most common malignancy. The aim of this study was to evaluate a possible role for positron emission tomography with [{sup 18}F]-2-fluoro-2-desoxy-glucose (FDG) in the initial staging and in therapy monitoring of pediatric patients suffering from biopsy-proven CD20-positive PTLD after solid organ transplantation. Seven pediatric patients were included. All available imaging studies - CT (n = 15), MRI (n = 16) and PET/PETCT (n = 16) - were reviewed on a lesion by lesion base. The performance of FDG-PET in the initial staging and during therapy with a chimeric anti-CD20 antibody was compared to conventional cross sectional imaging and correlated with the clinical outcome. FDG-PET identified all sites of disease as shown by CT/MRI and helped to clarify the significance of equivocal findings. The initial stage of disease was correctly identified by FDG-PET alone when compared to CT/MRI. During therapy, FDG-PET was superior to conventional cross-sectional imaging in the early evaluation of response.

    The 57th American Society of Haematology (ASH) meeting held in Orlando, FL was certainly the year when myeloma management changed for good, with a plethora of newly Food and Drug Administration (FDA)-approved drugs showing impressive outcome improvements and the introduction of new techniques for disease monitoring. Also, chimeric antigen receptor (CAR) T cells continued their triumphal march, consolidating their success in lymphoma and chronic lymhocytic leukaemia (CLL) and venturing into new fields such as again multiple myeloma. Some experimental drugs showed long-awaited results (midostaurin in FLT3-mutated acute myeloid leukaemia (AML)) and some brand new drugs showed promising results in the clinic after extensive preclinical studies, such as those targeting new epigenetic factors (histone methyltransferases) and apoptosis.

    Full Text Available BACKGROUND Bone Marrow Trephine Biopsy (BMTB and aspiration is critical for diagnosis, prognostic evaluation and monitoring therapeutic response. BMTB is of greater value in assessing cellularity, degree of fibrosis, marrow architecture and especially when aspiration is dry tap. At the same time, it provides sample for immunohistochemistry. MATERIALSAND METHODS It is a single centre observational study conducted from July 2014 to July 2016 in Department of Pathology, S.C.B. Medical College, Cuttack, which included both cell block and touch imprint along with trephine biopsy. Cases selected where lymphoma studied for pattern and extent of infiltration. Aspiration with dry tap and selected cases of myeloproliferative disorders, myelodysplastic syndrome, leukaemia (both acute and chronic, anaemia, multiple myeloma were studied. Jamshidi needle was used for biopsy. Samples obtained were formalin preserved, kept in decalcification solution (Hammersmith protocol and H and E slides prepared. Special stain-like reticulin and Masson’s trichrome were used for grading of fibrosis. Immunohistochemistry was done on selected cases of lymphoma. RESULTS Out of total 100 cases studied, 60 were of haematopoietic and lymphoid neoplasms, 12 anaemia, 20 secondary metastasis, 8 miscellaneous (1 haemophagocytic lymphohistiocytic disease, 1 storage disease, 1 granulomatous and 5 ITP. CONCLUSION The study was conducted to establish the advantage of bone marrow biopsy in inadequate and failed aspiration, but both are complementary to each other and together provide a comprehensive evaluation of the bone marrow. Bone marrow fibrosis are well accessed and increased detection of tumour cells in suspected secondary metastasis. Special stains, IHC, cytogenetic study can be done over biopsy block.

    Pediatric solid malignancies display important angiogenic potential, and blocking tumor angiogenesis represents a new therapeutic approach for these patients. Recent studies have evidenced rare circulating cells with endothelial features contributing to tumor neovascularization and have shown the pivotal role of bone marrow-derived (BMD) progenitor cells in metastatic disease progression. We measured these cells in patients with pediatric solid malignancies as a prerequisite to clinical trials with antiangiogenic therapy. Peripheral blood was drawn from 45 patients with localized (n = 23) or metastatic (n = 22) disease, and 20 healthy subjects. Subsets of circulating vascular endothelial growth factor receptor (VEGFR)2+-BMD progenitor cells, defined as CD45-CD34+VEGFR2(KDR)+7AAD- and CD45(dim)CD34+VEGFR2+7AAD- events, were measured in progenitor-enriched fractions by flow cytometry. Mature circulating endothelial cells (CEC) were measured in whole blood as CD31+CD146+CD45-7AAD- viable events. Data were correlated with VEGF and sVEGFR2 plasma levels. The CD45-CD34+VEGFR2(KDR)+7AAD- subset represented <0.003% of circulating BMD progenitor cells (< or =0.05 cells/mL). However, the median level (range) of the CD45(dim)CD34+VEGFR2+7AAD- subset was higher in patients compared with healthy subjects, 1.5% (0%-10.3%) versus 0.3% (0%-1.6%) of circulating BMD progenitors (P < 0.0001), and differed significantly between patients with localized and metastatic disease, 0.7% (0%-8.6%) versus 2.9% (0.6%-10.3%) of circulating BMD progenitors (P < 0.001). Median CEC value was 7 cells/mL (0-152 cells/mL) and similar in all groups. Unlike VEGFR2+-BMD progenitors, neither CECs, VEGF, or sVEGFR2 plasma levels correlated with disease status. High levels of circulating VEGFR2+-BMD progenitor cells correlated with metastatic disease. Our study provides novel insights for angiogenesis mechanisms in pediatric solid malignancies for which antiangiogenic targeting of VEGFR2+-BMD progenitors

    This study aimed to explore the dyadic relationships between unmet need, depression, and anxiety in people diagnosed with haematological cancer and their support persons. Adult survivors (18 years+) who had been diagnosed with a haematological cancer were recruited to a cross-sectional mailed survey via five state cancer registries in Australia. Participating survivors invited a support person to also complete a survey. Structural equation modelling was used to explore the relationships among survivor and support person self-reported depression, anxiety, and unmet needs. Of the 4299 eligible haematological cancer survivors contacted by the registries, 1511 (35%) returned a completed survey as did 1004 support persons. There were 787 dyads with complete data. After adjusting for age, gender, rurality, cancer type, and whether the support person was a relative, positive correlations were found between survivor and support person scores for depression (p = 0.0029) and unmet needs (p < 0.001), but not anxiety scores (p = 0.075). Survivor unmet needs were significantly related to support person depression (p = 0.0036). Support person unmet needs were significantly related to a higher depression score for survivors (p = 0.0067). Greater support person unmet needs were significantly related to a higher anxiety score for survivors (p = 0.0083). Survivor unmet needs did not have a significant relationship to support person anxiety (p = 0.78). Unmet needs may mediate the interdependence of psychosocial experiences for survivors and support persons, although a longitudinal study is required to confirm causality. Addressing unmet needs may be a potential target for improving outcomes for both groups.

    Background Data on paediatric reference laboratory values are limited for sub-Saharan Africa. Objective To describe the distribution of haematological and chemical pathology values among healthy infants from Malawi and Uganda. Methods A cross-sectional study was conducted among healthy infants, 0–6 months old, born to HIV-uninfected mothers recruited from two settings in Blantyre, Malawi and Kampala, Uganda. Chemical pathology and haematology parameters were determined using standard methods on blood samples. Descriptive analyses by age-group were performed based on 2004 Division of AIDS Toxicity Table age categories. Mean values and interquartile ranges were compared by site and age-group. Results A total of 541 infants were included altogether, 294 from Malawi and 247 from Uganda. Overall, the mean laboratory values were comparable between the two sites. Mean alkaline phosphatase levels were lower among infants aged ≤21 days while aspartate aminotransferase, creatinine, total bilirubin and gamma-glutamyl transferase were higher in those aged 0–7 days than in older infants. Mean haematocrit, haemoglobin and neutrophil counts were higher in the younger age-groups (<35 days) and overall were lower than US norms. Red and white blood cell counts tended to decrease after birth but increased after ~2 months of age. Mean basophil counts were higher in Malawi than in Uganda in infants aged 0–1 and 2–7 days; mean counts for eosinophils (for age groups 8–21 or older) and platelets (for all age groups) were higher in Ugandan than in Malawian infants. Absolute lymphocyte counts increased with infant age. Conclusion The chemical pathology and haematological values in healthy infants born to HIV-uninfected mothers were comparable in Malawi and Uganda and can serve as useful reference values in these settings.

The research was conducted on hybrid pigs [(Yorkshire × Landrace × Duroc] in a farm from Sălaj County, Romania. Pigs of 11 weeks (n = 200 were divided into 4 equal groups: a group fed with the probiotic, a prebiotic-fed group, a control group and a synbiotic (pre- and probiotic treated group. The control group was fed with a feed without the specified additives. Probiotic treated group was fed the same feedstuff but containing the additive Beta Plus® Ultra (Biochem( 5.12x1012 CFU / kg - Bacillus subtilis DSM 5750, 5.12x1012UFC / kg - Bacillus licheniformis (DSM 5749 and 921 g of betaine, in an amount of 1 kg / tonne of feed.  Prebiotic group had added to the feed an extract derived from the cell wall of Saccharomyces cerevisiae (TechnoMos® - Biochem in a dose of 250 g / ton of feed. The weight of 25 pigs in each compartment was recorded 9 times (over 85 days. Animal health was evaluated via clinical, haematological, and parasitological examinations. 5 rectal swabs were collected on day 11 and day 77 and faeces samples were taken in day 77 from each investigated group. Growth rate, feed consumption and some haematological parameters were measured. The body weight, average total weight gain and feed conversion rate increase by the dietary inclusion of the both pre and probiotic (p˃0.05. In the compartment treated with prebiotic the weight of the pigs has increased by 1030 g/day compared with 982 g/day value recorded in the control group. The average feed consumption was 3.21 kg/day in the control group while the group treated with prebiotic was only 2.99 kg/day. Feed conversion rate for all treated groups were lower than the one of control. Haematological parameters varied in physiological limits of species. Conclusion: These products show

    Full Text Available Reference values are very important in clinical management of patients, screening participants for enrollment into clinical trials and for monitoring the onset of adverse events during these trials. The aim of this was to establish gender-specific haematological and biochemical reference values for healthy adults in the central part of Ghana.A total of 691 adults between 18 and 59 years resident in the Kintampo North Municipality and South District in the central part of Ghana were randomly selected using the Kintampo Health and Demographic Surveillance System and enrolled in this cross-sectional survey. Out of these, 625 adults made up of 316 males and 309 females were assessed by a clinician to be healthy. Median values and nonparametric 95% reference values for 16 haematology and 22 biochemistry parameters were determined for this population based on the Clinical Laboratory and Standards Institute guidelines. Values established in this study were compared with the Caucasian values being used currently by our laboratory as reference values and also with data from other African and western countries.REFERENCE VALUES ESTABLISHED INCLUDE: haemoglobin 113-164 g/L for males and 88-144 g/L for females; total white blood cell count 3.4-9.2 × 10(9/L; platelet count 88-352 × 10(9/L for males and 89-403 × 10(9/L for females; alanine aminotransferase 8-54 U/L for males and 6-51 U/L for females; creatinine 56-119 µmol/L for males and 53-106 µmol/L for females. Using the haematological reference values based on the package inserts would have screened out up to 53% of potential trial participants and up to 25% of the population using the biochemical parameters.We have established a panel of locally relevant reference parameters for commonly used haematological and biochemical tests. This is important as it will help in the interpretation of laboratory results both for clinical management of patients and safety monitoring during a trial.

    2012-09-01

    Full Text Available This study was conducted in 16 healthy immature dromedary camels weighing 120-150 kg to evaluate and compare the effects of epidural and intramuscular injections of xylazine administered at 0.1 mg/kg and 0.2 mg/kg. Haematological parameters included haemoglobin, packed cell volume, total erythrocyte count and total leukocyte count. Biochemical parameters included alkaline phosphates, alanine aminotransferase, aspartate aminotransferase, blood urea nitrogen, creatinine and glucose. Parameters were measured at different intervals before (baseline and after the administration of drugs. Our study showed that the effect of xylazine on haematological and biochemical parameters is dose-dependant and is also related to the route of administration. The low dose of xylazine administered using both intramuscular and epidural methods showed minimal effects, whereas high doses of the drug, especially when injected intramuscularly, caused greater changes in haematological and biochemical parameters.

    We compared serotypes, virulence factors and susceptibility to antibiotics of Escherichia coli strains isolated from 282 patients with bacteraemia. Thirty-five of these were neutropenic patients with haematological malignancy and 247 were patients with a normal or raised total white blood cell......-haematological patients had recurrences with a strain different from the strain isolated in a previous episode. A possible connection between shorter intervals and recurrence with identical strains is discussed. We suggest that strains from recurrent E. coli bacteraemia are sent to a reference laboratory for serotyping...... count and no haematological malignancy. Strains isolated from recurrent bacteraemia were also bio- and ribotyped. Overall, no significant difference was found between O serogroups, K antigens, serum sensitivity, production of haemolysin, expression of P-fimbriae and patterns of antibiotic susceptibility...

    Full Text Available Neoplastic dissemination to the leptomeninges is an increasingly common occurrence in patients with both haematological and solid tumors arising outside the central nervous system. Both refinement of diagnostic techniques (Magnetic resonance imaging and increased survival in patients treated with targeted therapies for systemic tumors account for this increased frequency. Cerebrospinal fluid cytological analysis and MRI confirm clinical diagnosis based on multifocal central nervous system signs/symptoms in a patient with known malignancy. Overall survival in patients with leptomeningeal neoplastic dissemination from solid tumors is short, rarely exceeding 3-4 months. However, selected patients may benefit from aggressive therapies, Apart from symptomatic treatment, intrathecal chemotherapy is used, with both free (methotrexate, Thiotepa, AraC and liposomal antitumor agents (liposomal AraC. Palliative radiotherapy is indicated only in cases of symptomatic bulky disease, surgery is limited to positioning of Ommaya recervoirs or C5F shunting. We report clinical data on a cohort of 26 prospectively followed patients with neoplastic leptomeningitis followed in Lombardia, Italy, in 2011. Prognostic factors and pattern of care are reported.

    Strawberry tree (Arbutus unedo L., Ericaceae) leaves represent a potent source of biologically active compounds and have been used for a long to relieve symptoms of various health impairments and diseases. Two major compounds related to their beneficial activities in animals and humans are arbutin and hydroquinone. To establish potential benefit/risk ratio associated with daily oral administration of strawberry tree water leaf extract, arbutin and hydroquinone in doses expected to be non-toxic. We performed a 14-day and a 28-day study on male and female Lewis rats and evaluated main haematological parameters and the effects of treatments on the levels of primary DNA damage in white blood cells (WBC) using the alkaline comet assay. Our findings suggest no significant changes in the haematological parameters following prolonged exposure to strawberry tree water leaf extract, arbutin, and hydroquinone. However, hydroquinone causes increased, and extract as well as arbutin decreased WBC count in male rats compared to control after 14 days of treatment. DNA damage measured in WBC of rats treated with all compounds was below 10% of the DNA in the comet tail, which indicates low genotoxicity. The genotoxic potential of strawberry water leaf extract was within acceptable limits and reflected effects of a complex chemical composition upon DNA. We also observed slight gender- and exposure time- related differences in primary DNA damage in the leucocytes of control and treated rats. Future studies should investigate which doses of strawberry tree water leaf extract would be most promising for the potential use as a substitute for bearberry leaves for treatment of urinary infection.

    The similarities between swine and humans in physiological and genomic patterns, and the great correlation in size and anatomy, make pigs extremely useful in preclinical studies. New-born piglets can represent a model for congenital and genetic diseases in new-born children. It is known that piglets may have significant differences in clinicopathological results compared to adult pigs. Therefore, adult laboratory reference intervals cannot be applied to piglets. The aim of this study was to compare haematological and chemical variables in piglets of two ages and determinate age-related reference intervals for commercial hybrid young pigs. Blood samples were collected under general anaesthesia from 130 animals divided into five- (P5) and 30- (P30) day-old piglets. Only P30 animals were treated with parenteral iron after birth. Samples were analysed using automated haematology (ADVIA 2120) and chemistry analysers, and age-related reference intervals were calculated. Significant higher values of RBC, Hb and HCT were observed in P30 animals when compared to P5, with an opposite trend for MCV. These results were associated with a reduction of the RBC regeneration process and the thrombopoietic response. The TSAT and TIBC were significantly higher in P30 compared to P5; however, piglets remained iron deficient compared to adult reference intervals reported previously. In conclusion, this paper emphasises the high variability occurring in clinicopathological variables between new-born and 30-day-old pigs, and between piglets and adult pigs. This study provides valuable reference data for piglets at precise ages and could be used in the future as historical control improving the Reduction in animal experiments, as suggested by the 3Rs principle.

    Two years ago we reported about the development of solid state laser source for medical skin treatment with wavelength 310.6 nm and average power 200 mW. Here we describe the results of investigation of the advanced version of the laser, which is a more compact device with increased output power and flat top beam profile. Ti: Sapphire laser, the main module of our source, was modified and optimized such, that UV average power of the device was increased 1.7 times. Fiber optic homogenizer was replaced by articulated arm with diffraction diffuser, providing round spot with flat profile at the skin. We investigated and compare characteristics of Ti: Sapphire lasers with volume Bragg grating and with fused silica transmission grating, which was used first time for Ti: Sapphire laser spectral selection and tuning. Promising performance of last gratings is demonstrated.

    Haematological (WBC, RBC, Hgb and Hct) and genotoxicity (MNT) parameters, hepatic enzymatic activities (GST, GPx and GR), and a histopathological evaluation of liver, kidneys and gonads were assessed as general biomarkers of metal pollution in the shrew Crocidura russula inhabiting a pyrite mining area. Specimens exposed to metals presented a few significant alterations when compared with reference animals: GST activity decreased; micronuclei increased; and evident liver alterations related to metal exposure were observed. On the basis of all the parameters studied, age was an important factor that partly explained the observed variation, whereas sex was the least important factor. Significant correlations were also found between heavy metal concentrations and biomarkers evaluated, demonstrating the great influence of these metals in the metabolic alterations. To the best of our knowledge, these data constitute the first measurements of a battery of biomarkers in shrews from a mine site and are among the few available for insectivorous mammals. - Metals from an abandoned pyrite mine produce alterations in haematological parameters, GST, MNT, and histopathology in shrews

    Full Text Available This prospective longitudinal study investigated the progression of haematological changes in 32 transfused and 54 non-transfused dogs naturally infected with Babesia rossi over the 1st 6 days following diagnosis and treatment. The effect of patient age on the results of complete blood counts was determined. Haematology data were analysed at presentation and at 24 hours, 3 days and 6 days after presentation. Dogs were treated with diminazene aceturate at diagnosis and a blood transfusion was given if deemed clinically required. Mildly to moderately regenerative normocytic normochromic anaemia was observed in all dogs throughout the study period. Transfused dogs more often had an inflammatory leukogram at presentation and at 24 hours, than dogs that were not transfused. In dogs with a left shift, a concurrent normal or decreased segmented neutrophil count was found more commonly than neutrophilia. Severe thrombocytopenia that resolved within a week was common. Blood transfusion alleviated the anaemia, but had no significant effect on white blood cell or platelet responses. Blood cell responses were not significantly influenced by age. In conclusion, the red blood cell and white blood cell responses were less than expected in dogs with babesiosis, given the degree of anaemia and inflammation present. The magnitude of thrombocytopenia and rapid return of the platelet count to normal suggested a possible immune-mediated mechanism for the thrombocytopenia.

    Full Text Available Identify risk factors for Clostridium difficile infection (CDI and assess CDI outcomes among Australian patients with a haematological malignancy.A retrospective cohort study involving all patients admitted to hospitals in Western Australia with a haematological malignancy from July 2011 to June 2012. Hospital admission data were linked with all hospital investigated CDI case data. Potential risk factors were assessed by logistic regression. The risk of death within 60 and 90 days of CDI was assessed by Cox Proportional Hazards regression.There were 2085 patients of whom 65 had at least one CDI. Twenty percent of CDI cases were either community-acquired, indeterminate source or had only single-day admissions in the 28 days prior to CDI. Using logistic regression, having acute lymphocytic leukaemia, neutropenia and having had bacterial pneumonia or another bacterial infection were associated with CDI. CDI was associated with an increased risk of death within 60 and 90 days post CDI, but only two deaths had CDI recorded as an antecedent factor. Ribotyping information was available for 33 of the 65 CDIs. There were 19 different ribotypes identified.Neutropenia was strongly associated with CDI. While having CDI is a risk factor for death, in many cases it may not be a direct contributor to death but may reflect patients having higher morbidity. A wide variety of C. difficile ribotypes were found and community-acquired infection may be under-estimated in these patients.

    The objective of this observational study is to describe clinical, haematological and serum biochemical findings of horses affected with alfalfa dodder (Cuscuta campestris) toxicity. Twenty horses naturally exposed to alfalfa dodder toxicity were examined and information was collected on history and clinical signs. Physical examination was done on horses in the premises (n=20), and venous blood samples of 12 horses were submitted for haematology and serum biochemical examination for each horse. Abnormal clinical signs started around 36 hours after horses were fed the contaminated alfalfa. Abnormal signs were seen in 11 horses and those included diarrhoea (n=8), decreased appetite (n=7), neurological signs (n=4) and abdominal pain (n=1). Some horses had multiple clinical signs of the above. The results of complete blood cell count revealed leukocytopenia, neutropenia and thrombocytopenia. Serum biochemical analysis revealed decreased ALP, AST and CPK levels and increased direct bilirubin level. The used alfalfa was stopped immediately and a different alfalfa from a new container that did not contain any weeds was fed. Horses on the premises were observed closely, and the abnormal clinical signs resolved within three days. No treatment was implemented. Knowledge about toxicity of horses by Cuscuta species is scarce in the English veterinary literature and very limited.

    2015-10-01

    Full Text Available Introduction: Though nutrition is a key input to blood formation, little is known about the extent maternal dietary quality contributes to the haematological status of pregnant women in Northern Region of Ghana. Objective: The aim of this study was to assess the independent contribution of dietary diversity to haematological status of pregnant women whilst controlling for potential confounding factors including malarial infection. Methods: A cross-sectional study design was used on a sample of 307 pregnant women in their third trimester. A structured questionnaire was used to collect socio-demographic characteristics, obstetric and dietary data related to anaemia. Overall dietary quality was assessed using the dietary diversity score. Haemoglobin concentration (Hb was measured using portable HemoCueR Hb 301 system. Predictors of anaemia were estimated using multiple linear regression analysis. Results: The mean Hb was 10.8±1.4 g/dl and prevalence of anaemia (Hb < 11.0 g/dl was 46.3 %. High dietary diversity score [Beta coefficient (β, = 0.141 p < 0.001], multi-gravidity (β=0.205 and high composite score for ANC content (β= 0.201 were associated with a decreased risk of anaemia in the third trimester of pregnancy. Conclusion: The findings suggest the need to strengthen interventions that focus on improving the consumption of diversified foods particularly during pregnancy.

    One of the supporting factors to have good aerobic endurance requires high VO2 max levels supported by good quality and quantity level of Haematology parameter especially such as erythrocytes, hematocrit and hemoglobin. One of the components in hemoglobin is iron which functions as theoxygen transport to parts of all body required in the process of metabolism. The objective of this research was to find out the difference between VO2 Max and Haematology parameter between iron supplying and no iron supplyingonmenstrual woman. The type of this research is quasi experimental research with non-randomized control group Pretest-Postest Design. The subjectsarethe studentsat faculty of Sports Sciences, Medan State University with the criteria of female gender, monthly regular menstrual cycle, having the level of health and the level of training, willing to be a sample by filling out informed consent. The total number of research subjectsis twenty students, divided into two groups namely the treatment group and the control group. The hematology parameter was measuredby Haemotology analyzer and VO2 Max was measured by multi-stage run. The result showed that there was a significant effect of iron supplyingon the increase of erythrocyte level on menstrual women, hemotocrit, haemoglobin and an increase in VO2 Max. Iron supplying on menstrual woman has the effect on the increase of erythrocyte, hematocrit, hemoglobin level and VO2 Max

    1982-12-01

    A haematological and biochemical investigation was undertaken in 122 consecutive male patients with suspected organic solvent poisoning due to exposure to a mixture of organic solvents such as turpentine, toluene and xylene. Sixty-four healthy solvent exposed and 91 healthy non-exposed male volunteers were used as controls. The only statistically significant differences were that in the patients (B)-leucocytes and S-creatinine were lower than in the controls. (B)-monocytes were higher in all exposed groups than in the controls. S-creatine kinase was higher in patients actually exposed at the examination time, than in all other groups. It is concluded that there was no characteristic haematological and biochemical pattern that could be of value in the individual diagnosis of organic solvent poisoning. The patients and the controls were seen as out-patients. In all groups studied, more than 10% of the results of reticulocytes, leucocytes, sedimentaition rate, orosomucoid and creatine kinase exceeded the upper level of the reference interval, which is based on in-patients. New reference intervals for these 5 analyses, valid for ambulantly examined subjects, should be worked out.

    Haematology parameters (N = 24) and serum biochemistry parameters (N = 35) were determined for wild Eurasian beavers (Castor fiber), between 6 months - 12 years old. Of the population tested in this study, N = 18 Eurasian beavers were from Norway and N = 17 originating from Bavaria but now living extensively in a reserve in England. All blood samples were collected from beavers via the ventral tail vein. All beavers were chemically restrained using inhalant isoflurane in 100% oxygen prior to blood sampling. Results were determined for haematological and serum biochemical parameters for the species and were compared between the two different populations with differences in means estimated and significant differences being noted. Standard blood parameters for the Eurasian beaver were determined and their ranges characterised using percentiles. Whilst the majority of blood parameters between the two populations showed no significant variation, haemoglobin, packed cell volume, mean cell haemoglobin and white blood cell counts showed significantly greater values (pbeavers or between sexually immature (beavers in the animals sampled. With Eurasian beaver reintroduction encouraged by legislation throughout Europe, knowledge of baseline blood values for the species and any variations therein is essential when assessing their health and welfare and the success or failure of any reintroduction program. This is the first study to produce base-line blood values and their variations for the Eurasian beaver.

    Full Text Available Thirty-two adult riverine buffaloes (Buhalis bubalus in their last trimester of pregnancy were selected and randomly divided into four groups. The buffaloes of group I served as control. Animals in group II, III and IV were treated twice (7 days apart with levamisole hydrochloride (0.5mg/kg b. w. orally, Etosol (Vit E+Se, 10ml, I/m and Bacilli Calmette Guerine (BCG (0.5 ml/animal, s/c, respectively. Blood samples were collected at weekly intervals starting day 0 untill parturition. Total erythrocytic count and packed cell volume values were higher (P<0.05 in levamisole and vit E+Se treated group of buffaloes. Haemoglobin concentration was higher (P<0.05 inVit E+Se treated group. MCV, MCH and MCHC remained unchanged among all the experimental groups. Total leukocyte count was higher (P<0.05 in levamisole treated group of buffaloes. Differential leukocyte counts (relative revealed moderate lymphocytosis in all immunomodulated groups with significantly higher counts in Vit E+Se treated buffaloes. It was inferred that levamisole and vit E-se altered some haematological values, whereas BCG did not affect the haematological parameters.

    Full Text Available   The present study investigated the effects of acute toxicity of malathion on behavioral and haematological parameters in the cyprinid Capoeta damascina. The specimens were collected from the Kordan River, Karaj, Iran in August, 2014 and were exposed to different concentrations of malathion at the laboratory (24, 48, 72 mg L‑1 based on 96h-LC (10; 30; 50; 90 which was 6.08 (5.22-7.18 mg L-1. The animals were then exposed to 0.76, 1.00 and 1.52 mg L-1 of malathion for 10 days. Blood samples were collected in days 1, 5 and 10. Red blood cell (RBC, white blood cell (WBC, hemoglobin (Hb, hematocrit (PVC, mean corpuscular volume (MCV, mean corpuscular hemoglobin (MCH, and mean corpuscular hemoglobin concentration (MCHC were measured. Behavioral abnormalities were observed in fishes exposed to high levels of malathion. The specimens exposed to malathion had significantly lower RBC, WBC, Hb, PVC but higher MCV and MCH than those of the control group. No significant difference was detected in MCHC the exposed and control specimens. Hematological parameters (except MCHC were significantly correlated with exposure time. In conclusion, malathion showed extensive haematological effects on C. damascina that might be used as bioindicator of this pesticide in flowing waters.

    investigations were done: Blood counts, IgM Dengue. Clinically, patients were monitored and platelet count, haematocrit, Hess test were repeated daily. DATA ANALYSIS Data collected will be analysed by frequency, percentage and mean. Dengue-IgM Capture ELISA Detection of dengue virus specific IgM Antibodies in serum. RESULTS Male to female ratio was 1.5:1. Majority of the cases having dengue infection belong to the age group of 21-30 years, wherein 48% belong to 21-30 years’ group and 24% belong to 31-40 years’ group. All the cases had fever (100%. Other common signs and symptoms included are myalgia (85%, headache (80%, joint pains (76%, vomiting (60%, pain abdomen (54%, rash (46%, hepatomegaly (25%, bleeding (21% and shock (5%. Signs suggestive of plasma leakage such as pedal oedema (12%, ascites (20%, pleural effusion (26% were present. Hess test was positive in 20% of the patients. Thrombocytopenia was found in 76% patients. Bradycardia was found in 41 %. CONCLUSIONS The present study had an objective of studying clinical manifestations and haematological profile associated with dengue fever. A positive Hess test should prompt close observation and early hospital referral, but a negative test does not exclude dengue infection. Bleeding tendencies should be closely watched for. When features of plasma leakage such as pedal oedema, pleural effusion, ascites are present, the patient should be closely watched for and should be immediately managed. The treatment of dengue is mainly supportive. However, appropriate fluid management plays a major role in outcome of the disease. Dengue sero-surveillance studies may give some idea about advent, intensity, transmission season, seasonal incidence, waxing and waning, and impending epidemic of dengue and DHF. A large-scale active longitudinal sero-survey along with the study of vector capacity and vector competence would provide more correct information.

  18. Comparison of Haematological Responses and Radiation Recovery in Several Mammalian Species

    1967-07-15

    The twenty-odd years since the beginning of modern radiation biology have covered a period during which our understanding of the pathology of the lethal radiation lesion has increased by tremendous bounds; however, for a number of reasons, not the least of which is the expense, the majority of these studies have been conducted on small laboratory animals. Based upon these studies, the classic picture of lymphopenia, thrombocytopenia, and granulocytopenia, occasionally accompanied by an anaemia, has been clearly documented. We have also seen the development and wide acceptance of the first-order model for exponential radiation injury recovery first formulated by Blair (1950). With the increasing body of knowledge on the effects of high doses of radiation on human beings, particularly commencing with the Marshall Islands accident, it became apparent that the generalized model of the haematological response of mammals based on rodent data, or even from data on dogs, was less than adequate. For this reason we started, about four or five years ago, to make a systematic comparison of the haematological response, the lethal dose, and the recovery kinetics of a number of mammalian species that would be broadly representative of the animal kingdom in size, dietary habits, life-span, and normal haematology. All radiations were carried out under conditions that would ensure the maximum possible precision of dosimetric measurement, and as uniform a distribution of tissue dose as could be achieved. For this purpose we used a General Electric 1-MeV resonant transformer X-ray generator. The half-value layer of the beam as it was used for these radiation exposures was 2 mm of lead, and the dose rate was 7 rad/min. It was possible to irradiate animals as large as the burro or the pig with a maximum deviation of dose rate over the field of {+-}3%. The target to animal midline distance was 2 m. For later studies a 15 kCi {sup 60}Co source was used for radiation exposures. The dose

    -glucan derived from oyster mushroom (Pleurotus ostreatus, Hiratake) shifts in haematological and biochemical profiling were found in half-year-old rainbow trout (O. mykiss) in environmental conditions of a commercial rainbow trout fishery. Biometrical indices were not found significantly altered. No specific effect of β-glucan on immune system response of rainbow trout was found in the study. The use of β-glucan in prosperous, clinically healthy aquaculture is still an issue, nevertheless, its use in breedings endangered by stress stimuli, infectious diseases or adverse environmental factors is indisputable.

    Granulocytic sarcoma, also known as myeloid sarcoma, is an extramedullary tumour composed of immature myeloid cells. Granulocytic sarcoma is typically found in patients with acute myeloid leukaemia, accelerated phase or blast crisis of chronic myeloid leukaemia, myelodysplastic syndrome, or as an isolated event without bone marrow involvement. We present a case of granulocytic sarcoma in a patient with chronic myeloid leukaemia in the setting of complete haematological, molecular and cytogenetic remission. Our patient was first treated with imatinib for chronic-phase chronic myeloid leukaemia. After maintaining remission for 42 months, he developed a granulocytic sarcoma in his spine. In this case report, we describe our case, along with the three other cases reported in the literature. In addition to being a rare diagnosis, this case demonstrates the importance of being vigilant in diagnosing the cause of back pain and atypical symptoms in patients with a history of leukaemia. 2014 BMJ Publishing Group Ltd.

    The biochemical and haematological effects of the seed powder of Mucuna pruriens in male rats were evaluated to establish some biological properties of this potential biopesticide currently undergoing investigation. The result showed that Mucuna pruriens seed extract produced a significant (p<0.05) increase in white blood cell (WBC) count, as well as in bilirubin concentrations, alkaline phosphatase (ALP), protein and creatinine levels measured. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were significantly reduced (P<0.05) in comparison with the experimental control. PCV, Hb, albumin level and WBC differential counts gave no significant difference between treated and control groups. The results revealed metabolic imbalance in the rats which suggests a mild cholestasis effect of the extract.

    To estimate the reference intervals for commonly used blood haematology and biochemical parameters in an adult (18-55yrs) population of residents of Mampong Akuapem. This was a population based cross sectional study of a randomly selected sample of the adult population of Mampong. The sample was selected from an updated census list of the Mampong area. Median values (95% range) for measured parameters were established as follows: Haemoglobin, (males) 14.2 g/dl (females) 12.0 g/dl Alanine aminotransferase (ALT), (female) 19.6 U/L (males) 26.1 U/L and Creatinine, (males) 108 mmol/L (females) 93 mmol/L. In comparison to reference values that are commonly used in Ghana, the haemoglobulin levels from this study were lower, and liver function parameters higher. This could be a result of genetic or environmental differences and calls for the need to establish site specific reference values applicable to our population.

    The 55th annual ASH meeting was held in pleasant New Orleans and was the largest in its history, with 22,495 participants coming from 113 nations. A 'bench-to-bedside and back' attitude characterises haematology probably more than any other discipline in medicine and, as usual, this was reflected in the extremely wide breadth of the topics covered, including the last results from clinical trials and cutting-edge advancements in basic science. This year, the balance was arguably skewed: few truly clinical practice-changing results were presented. On the other hand, a great number of basic and translational studies significantly increased our understanding of the biology of numerous malignancies and heralded the coming of age of disruptive technologies. Namely, above all, next generation sequencing and T cell engineering-based cell therapy.

    Some biochemical and haematological variables were measured in piglets during the first 48 hours after birth. The piglets were reared either by the sow, or bottle-fed with colostrum (either natural or sterilised by irradiation), or a commercial milk replacer. Mean haemoglobin concentrations, packed cell volumes and erythrocyte counts decreased by approximately 45 per cent in all the groups between birth and 48 hours, but leucocyte counts increased more markedly in the colostrum-fed groups. All the colostrum-fed groups showed rapid increases in serum total protein concentrations which were almost entirely due to increases in gamma globulin concentrations. There was no difference in this respect between natural colostrum and colostrum sterilised by irradiation with 500 Krad of gamma rays. Colostrum sterilised by irradiation can protect piglets against infectious agents and simplify the rearing of piglets under specific pathogen free conditions.

    In the blood sera of pigs vaccinated with inactivated vaccines manufactured by three different manufacturers the RIA method was used to determine the specific antibodies to the virus of Aujeszky's disease. In certain groups of vaccinated pigs the results of the RIA examination are unfavourably affected by the bond of antibodies to the cellular antigenous determinants. This proves that following vaccination antibodies are formed not only against the viral antigen but also against the antigens of cells on which the vaccination virus is propagated. These shortcomings are eliminated by the use of suitable cellular cultures for the preparation of viral and control antigens. Antigens are applicable for RIA and for ELISA examinations of blood sera of infected and vaccinated pigs. The advantages are described of the RIA and ELISA methods as compared with the virus neutralization test. (author)

    Normal values of complete blood counts show variation from region to region and between different ethnic groups. It is important to establish reference range for these values in our population for clinical use by our physicians. This descriptive cross sectional study aimed at establishing the normal reference values of complete blood counts in physically normal full term new borns of Panu Aqil, Rural Sind, Pakistan. Methods: The study was conducted at Combined Military Hospital, Panu Aqil Cantonment, from January 2010 to March 2011, on 316 term normal neonates selected on the basis of gestational age of 37 weeks or more with uneventful antenatal period. During the initial 12 hours of delivery, 2 ml Cord blood was collected in bottle containing tripotassium ethylene diamine tetra acetic acid (K3EDTA) as the anticoagulant and Complete blood counts were performed by Sysmex KX-21 automated haematology analyser. Blood films were prepared and stained by Leishman stain. Results: The haemoglobin was mean ± SD 15.4 ± 1.9 g/dL. The Mean Corpuscular Volume (MCV) was 103.4 ± 4.6 fL, while Mean Corpuscular haemoglobin (MCH) was 33.8 ± 1.6 pg. The Red cell Distribution Width-CV (RDW-CV) was 18.5 ± 1.8%. The total leukocyte count (TLC) was mean ± SD 13.7 ± 4.0*109 /L. The Absolute Neutrophil count (ANC) was mean+-SD 7.7 ± 3.0x109 /L. The Absolute Lymphocyte count (ALC) was mean+-SD 5.1 ± 1.8*109 /L. Platelet count was mean ± SD 285 ± 62x109 /L. Conclusion: Our values provide reference range for haematological values in healthy newborns of Panu Aqil, Rural Sindh, for clinical use by our physicians. (author)

    Full Text Available Background: Referral of samples for the work-up of haematological disorders from remote laboratories can result in a delay in analysis. Objective: The stability of the full blood count (FBC, differential count (DIFF, reticulocyte and peripheral blood smear (PBS morphology during extended storage was evaluated. Methods: Forty blood samples stored in ethylenediaminetetraacetic acid (EDTA were analysed on an ADVIA® 120 haematology analyser. The samples (25% abnormal; 75% normal were stored at room temperature (RT and at 4 °C – 8 °C. Analysis of samples stored at RT was performed every 12 hours for two days. Analysis of samples stored at 4 °C – 8 °C was performed at 12 hours and subsequently every 24 hours for seven days. Results: FBC parameters (red cell count, haemoglobin and DIFF parameters (percentages of basophils, lymphocytes and monocytes were stable for at least 48 hours when stored at RT. Platelets were only stable for 12 hours and the white cell count was stable for 36 hours when stored at RT. Storing samples at 4 °C – 8 °C significantly increased the stability of most parameters, in particular, mean cell volume and percentage of reticulocytes. However, DIFF parameters were associated with lower stability at 4 °C – 8 °C. PBS morphology was compromised prior to 12 hours whether stored at RT or at 4 °C – 8 °C. Conclusion: This study provides evidence that blood samples stored in EDTA at 4 °C – 8 °C for seven days are suitable for testing on the ADVIA® 120 analyser for the FBC and percentage of reticulocyte parameters. However, storage at 4 °C – 8 °C is not a solution for samples referred for DIFF and PBS morphology review.

    Full Text Available Haematology parameters (N = 24 and serum biochemistry parameters (N = 35 were determined for wild Eurasian beavers (Castor fiber, between 6 months - 12 years old. Of the population tested in this study, N = 18 Eurasian beavers were from Norway and N = 17 originating from Bavaria but now living extensively in a reserve in England. All blood samples were collected from beavers via the ventral tail vein. All beavers were chemically restrained using inhalant isoflurane in 100% oxygen prior to blood sampling. Results were determined for haematological and serum biochemical parameters for the species and were compared between the two different populations with differences in means estimated and significant differences being noted. Standard blood parameters for the Eurasian beaver were determined and their ranges characterised using percentiles. Whilst the majority of blood parameters between the two populations showed no significant variation, haemoglobin, packed cell volume, mean cell haemoglobin and white blood cell counts showed significantly greater values (p<0.01 in the Bavarian origin population than the Norwegian; neutrophil counts, alpha 2 globulins, cholesterol, sodium: potassium ratios and phosphorus levels showed significantly (p<0.05 greater values in Bavarian versus Norwegian; and potassium, bile acids, gamma globulins, urea, creatinine and total calcium values levels showed significantly (p<0.05 greater values in Norwegian versus Bavarian relict populations. No significant differences were noted between male and female beavers or between sexually immature (<3 years old and sexually mature (≥3 years old beavers in the animals sampled. With Eurasian beaver reintroduction encouraged by legislation throughout Europe, knowledge of baseline blood values for the species and any variations therein is essential when assessing their health and welfare and the success or failure of any reintroduction program.

    Full Text Available The health status of cows is evaluated and depending on haematological and biochemical profile of blood. Nutrition is the main technological factor that can produce profound changes in the metabolic profile in animals (Dhiman et al., 1991; Khaled et al., 1999; Ingvartsen, 2006. Blood parameters analyze can lead to identify if there are errors in nutrition of lactating cows (Payne et al., 1970. The aim of this study was the evaluation of metabolic and biochemical changes that occur during colostrum period and in terms of number of lactations in cows. The biological material was represented by a total of 60 heads of dairy cows from a family farm from Sălaj County, Romania. The cows are all from Holstein breed and presented no clinical signs of any specific pathology. Blood samples were collected from the jugular vein of each cow and analyzed. 10 individuals from each of the six lactations have been randomly selected. Haematological and biochemical parameters showed variations depending on factors analyzed here. In lactation 1 Hb was 7.55±3.05 (g/dl, while in lactation 6 the value was 12.5±2.10 (g/dl. RBC ranged as follows: in lactation 1 - 28.50±2.05 and in lactation 6 - 30.02±2.05. Lymphocytes varied within very wide limits under the influence of lactation: in lactation 1 - 2.8±1.56 and in lactation 6 - 7.55±1.80. The number of lactations and lactation rank have influenced blood biochemical and hematological parameters in dairy cows. Biochemical parameters are influenced by post-partum day, showing the lowest values in the early days of colostral period and the highest in the last few days of the same period.

    Full Text Available Objective: To investigate the effect of aqueous extract of Murraya koenigii leaves on some haematological, hormonal and serum lipid parameters in rats. Methods: We evaluated whether oral administration of Murraya koenigii affected the haematological, hormonal and lipid parameters. After 7 days of oral administration of 250 mg/ kg and 500 mg/kg body weight, other profiles were investigated. Results: The results showed that the extract administered significantly increased (P < 0.05 packed cell volume, haemoglobin concentration, red blood cell, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, mean corpuscular volume and decreased the platelet count (P < 0.05 at the dose of 250 mg/kg and 500 mg/kg body weight when compared with control. The extract significantly increased (P < 0.05 white blood cell count at all doses administered when compared with control. Results showed that thyronine and thyroxine were increased, while thyroid stimulating hormone was decreased significantly (P < 0.05 at high doses compared. The recorded data in the present study showed that the testosterone value was reduced significantly (P < 0.05 from control value. Also the extract significantly reduced (P < 0.05 the total cholesterol concentration and low density lipoproteins cholesterol concentration in the serum while it had no significant effect on serum high density lipoprotein cholesterol concentration at all doses administered. Conclusions: This study suggests that the extracts may have beneficial effect on serum cholesterol concentration, can act as a stimulant to thyroid functions as well as in anemia and immunity dependent disorders and also as a potent contraceptive.

    The Haematotoxic implications of exposure to petroleum fumes through inhalation in human subjects were investigated. A total of 400 subjects (200 males and 200 females) aged between 18-30 years participated. Each gender was further categorized into two groups of 100 each for control and test, respectively. The test group was again subdivided into test 1 (T1) and test 2 (T2) in both sexes. T1 subjects were exposed to petroleum fumes for two years and below while T2 subjects were exposed for more than two years. Samples of blood were collected daily and subjected to haematological analysis. The results obtained showed that in males and females, red blood cell counts (10(6) /mm3) was significantly [P < 0.001] decreased in T1 (4.4 +/- 0.13) and T2 (3.85 +/- 0.07) compared to control (4.76 +/- 0.01). White blood cell counts, haematocrit, haemoglobin concentration and mean corpusclular haemoglobin concentration (MCHC) were significantly [P < 0.01] decreased in both sexes of test groups when compared with control. There was also a significant [P < 0.001] decrease in mean corpuscular haemoglobin (MCH) and mean corpuscular volume (MCV) in test 2 males compared with control. Most subjects exposed for longer than two years (T2) had significantly [P < 0.001] lower values of red blood cell count, haemoglobin concentration and haematocrit than those exposed for less than two years. The odds/odds ratio that a subject would become anaemic progressively rose from less than 1 in the control to greater than 1 or infinity on exposure to petroleum fumes. These results indicate that the petroleum fumes cause a reduction in haematological indices which worsens with prolonged exposure.

    Tofacitinib is an oral Janus kinase inhibitor for the treatment of RA. The aim of this analysis was to characterize changes in haematological parameters following tofacitinib treatment, and to compare changes in haemoglobin with markers of disease activity, fatigue and vitality. Changes in neutrophil counts, lymphocyte counts and haemoglobin levels were analysed in patients with RA from six phase 3 randomized controlled trials (n = 4271) of tofacitinib 5 or 10 mg bd, placebo or active comparators of up to 24 months' duration, and two long-term extension (LTE) studies (n = 4858) of tofacitinib of up to 84 months' duration. Disease activity markers included CRP and ESR. Fatigue and vitality were assessed using the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) and Short Form Health Survey-36 vitality domain scores. In phase 3 studies, mean neutrophil and lymphocyte counts decreased and mean haemoglobin levels increased in all tofacitinib treatment groups. Haemoglobin levels and neutrophil counts stabilized in the LTE studies, while lymphocyte count decreases stabilized at approximately month 48. Increased haemoglobin was associated with decreased ESR and CRP levels. Clinically meaningful reductions in haemoglobin levels (⩾3 g/dl from baseline or haemoglobin ⩽7 g/dl) occurred in tofacitinib treatment, which stabilized over time in the LTE studies. Changes in haemoglobin levels, although associated with changes in ESR and CRP, were not associated with fatigue or vitality. © The Author 2016.

  17. Nanocrystalline solids

    Gleiter, H.

    1991-01-01

    Nanocrystalline solids are polycrystals, the crystal size of which is a few (typically 1 to 10) nanometres so that 50% or more of the solid consists of incoherent interfaces between crystals of different orientations. Solids consisting primarily of internal interfaces represent a separate class of atomic structures because the atomic arrangement formed in the core of an interface is known to be an arrangement of minimum energy in the potential field of the two adjacent crystal lattices with different crystallographic orientations on either side of the boundary core. These boundary conditions result in atomic structures in the interfacial cores which cannot be formed elsewhere (e.g. in glasses or perfect crystals). Nanocrystalline solids are of interest for the following four reasons: (1) Nanocrystalline solids exhibit an atomic structure which differs from that of the two known solid states: the crystalline (with long-range order) and the glassy (with short-range order). (2) The properties of nanocrystalline solids differ (in some cases by several orders of magnitude) from those of glasses and/or crystals with the same chemical composition, which suggests that they may be utilized technologically in the future. (3) Nanocrystalline solids seem to permit the alloying of conventionally immiscible components. (4) If small (1 to 10 nm diameter) solid droplets with a glassy structure are consolidated (instead of small crystals), a new type of glass, called nanoglass, is obtained. Such glasses seem to differ structurally from conventional glasses. (orig.)

    The role of antiviral prophylaxis for the prevention of posttransplant lymphoproliferative disease (PTLD) remains controversial for solid organ transplantation (SOT) recipients who are seronegative for Epstein-Barr virus (EBV) but who received organs from seropositive donors. We performed a systematic review and meta-analysis to address this issue. Two independent assessors extracted data from studies after determining patient eligibility and completing quality assessments. Overall, 31 studies were identified and included in the quantitative synthesis. Nine studies were included in the direct comparisons (total 2366 participants), and 22 were included in the indirect analysis. There was no significant difference in the rate of EBV-associated PTLD in SOT recipients among those who received prophylaxis (acyclovir, valacyclovir, ganciclovir, valganciclovir) compared with those who did not receive prophylaxis (nine studies; risk ratio 0.95, 95% confidence interval 0.58-1.54). No significant differences were noted across all types of organ transplants, age groups, or antiviral use as prophylaxis or preemptive therapy. There was no significant heterogeneity in the effect of antiviral prophylaxis on the incidence of PTLD. In conclusion, the use of antiviral prophylaxis in high-risk EBV-naive patients has no effect on the incidence of PTLD in SOT recipients. © Copyright 2016 The American Society of Transplantation and the American Society of Transplant Surgeons.

    To date, observational studies in nutrition have categorized foods into groups such as dairy, cereals, fruits, and vegetables. However, the strength of the association between food groups and chronic diseases is far from convincing. In most international expert surveys, risks are most commonly scored as probable, limited, or insufficient rather than convincing. In this position paper, we hypothesize that current food classifications based on botanical or animal origins can be improved to yield solid recommendations. We propose using a food classification that employs food processes to rank foods in epidemiological studies. Indeed, food health potential results from both nutrient density and food structure (i.e., the matrix effect), both of which can potentially be positively or negatively modified by processing. For example, cereal-based foods may be more or less refined, fractionated, and recombined with added salt, sugars, and fats, yielding a panoply of products with very different nutritional values. The same is true for other food groups. Finally, we propose that from a nutritional perspective, food processing will be an important issue to consider in the coming years, particularly in terms of strengthening the links between food and health and for proposing improved nutritional recommendations or actions. © 2015 American Society for Nutrition.

    Laboratory rat Rattus norvegicus. fed on poultry growers mash plus additional protein supplements and some heavy metals, was studied for the growth and the haematological parameters. All the dietary supplements resulted in an increase in the growth of the rats. The rats, fed on growers mash and prawn meal showed the best growth within 7 weeks. Effects of diets were significantly, correlated at 0.01 level. Weight loss was recorded in case of all heavy Metal-laced diets, however, calcium sulphate-laced diets resulted in an increase in growth. Mercurous chloride was the most toxic salt which resulted in the greatest weight loss. Haematological analysis of rats revealed that RBC/sub s/ were higher in the case of heavy metal-laced diets than heavy metal-free diets. Generally, RBC counts were higher in females than in males within a group. Fish meal and prawn meal feeding. (author)

    A Phase I dose escalation first in man study assessed maximum tolerated dose (MTD), dose-limiting toxicity (DLT) and recommended Phase II dose of TP300, a water soluble prodrug of the Topo-1 inhibitor TP3076, and active metabolite, TP3011. Eligible patients with refractory advanced solid tumors, adequate performance status, haematologic, renal, and hepatic function. TP300 was given as a 1-hour i.v. infusion 3-weekly and pharmacokinetic (PK) profiles of TP300, TP3076 and TP3011 were analysed. Polymorphisms in CYP2D6, AOX1 and UGT1A1 were studied and DNA strand-breaks measured in peripheral blood mononuclear cells (PBMCs). 32 patients received TP300 at 1, 2, 4, 6, 8, 10, 12 mg/m 2 . MTD was 10 mg/m 2 ; DLTs at 12 (2/4 patients) and 10 mg/m 2 (3/12) included thrombocytopenia and febrile neutropenia; diarrhoea was uncommon. Six patients (five had received irinotecan), had stable disease for 1.5-5 months. TP3076 showed dose proportionality in AUC and C max from 1–10 mg/m 2 . Genetic polymorphisms had no apparent influence on exposure. DNA strand-breaks were detected after TP300 infusion. TP300 had predictable hematologic toxicity, and diarrhoea was uncommon. AUC at MTD is substantially greater than for SN38. TP3076 and TP3011 are equi-potent with SN38, suggesting a PK advantage. EU-CTR2006-001345-33

    Full Text Available Amygdalin is a cyanogenic glycoside initially obtained from the seeds of bitter almonds. It is composed of one molecule of benzaldehyde, two molecules of glucose and one molecule of hydrocyanic acid. Various ways of amygdalin application play a different role in recipient organism. Intravenous infusion of amygdalin produced neither cyanidemia nor signs of toxicity, but oral administration resulted in significant blood cyanide levels. The present in vivo study was designed to reveal whether amygdalin is able to cause changes in the haematological profile and thus alter the physiological functions, using rabbits as a biological model. Adult male rabbits (n = 20 were randomly divided into five groups: the control group without any amygdalin administration, two experimental groups received a daily intramuscular injection of amygdalin at a dose 0.6 and 3.0 mg.kg-1 b.w. and other two groups were fed by crushed apricot seeds at dose 60 and 300 mg. kg-1 b.w., mixed with commercial feed over the period of 14 days. After two weeks, haematological parameters in whole blood were analysed (WBC - total white blood cell count, LYM - lymphocytes count, MID - medium size cell count, GRA - granulocytes count, RBC - red blood cell count, HGB - haemoglobin, HCT - haematocrit, MCV - mean corpuscular volume, MCH - mean corpuscular hemoglobin, MCHC - mean corpuscular hemoglobin concentration, RDWc - red cell distribution width, PLT - platelet count, PCT - platelet percentage, MPV - mean platelet volume, PDWc - platelet distribution width using haematology analyser Abacus junior VET. Our findings indicate that intramuscular and oral application of amygdalin for two weeks did not significantly affect the haematology parameters in experimental animals. In this study, no obvious beneficial or negative effects of amygdalin administration on the blood of male rabbits were observed.

    Free-ranging brown bears exhibit highly contrasting physiological states throughout the year. They hibernate 6 months of the year, experiencing a decrease in body temperature, heart rate, respiratory rate and metabolism. An increase in food consumption and the resulting weight gain (mostly through fat storage) prior to hibernation are also part of the brown bear's annual cycle. Due to these physiological changes, haematological and biochemical variables vary dramatically throughout the year. Seasonal changes in 12 haematological and 34 biochemical variables were evaluated in blood samples collected from 40 free-ranging subadult brown bears (22 females, 18 males) immobilised in Sweden in winter (February-March), spring (April-May), and summer (June). Higher levels of haemoglobin, haematocrit and red blood cell count, and a lower white blood cell count and mean cell volume was found during hibernation than in spring and summer. Lower values of the enzymes; aspartate aminotransferase (AST), alanine transaminase (ALT), alkaline phosphatase (AP), γ-glutamyl transpeptidase (GGT), glutamate dehydrogenase (GD) and amylase, and increased values of β-hydroxybutyrate (β-HBA) and blood lipids; triglycerides, cholesterol and free fatty acids, were present during hibernation compared to spring and summer. This study documents significant shifts in haematological and biochemical variables in samples collected from brown bears anaesthetised in winter (February-March) compared to in spring and summer (April-June), reflecting the lowered metabolic, renal and hepatic activity during hibernation. Lower values of enzymes and higher values of blood lipids during hibernation, likely reflect a lipid-based metabolism.

    Full Text Available Aim : To study the influence of housing system and dietary supplementation of probiotics and enzymes on haematological parameters of rabbits. Materials and Methods: A total of 144 weaned rabbits were divided into 2 groups of 72 in each group and housed under conventional cage system and backyard system. The rabbits in each housing system were divided into 4 groups of 18 in each group and the diets were supplemented with probiotics, enzymes and both. Results: The housing system and supplementation of probiotics and enzymes did not exert significant influence on any of the haematological parameters studied. However, there was slight positive influence of probiotic and enzyme supplementation on the health status of rabbits as revealed by haematological parameters. The overall mean Total erythrocyte count, total leucocyte count, lymphocytes, neutrophils, eosinophils, monocytes, haemoglobin and packed cell volume were 7.52, 6.29 (103/mm3, 60.27%, 35.71%, 1.35%, 1.92%, 10.67 g/dl and 34.25%, respectively. Conclusion: Rabbits can be reared on low input backyard system without any adverse effect on health and supplementation of probiotics and enzymes had a positive influence on health status of rabbits.

    Full Text Available It is established that haematological and biochemical parameters provide important data to assess the physiological condition and health status of wild birds. To undertake conservation physiology or ecophysiology work, it is therefore essential to establish baseline physiological parameters and how these parameters change with age and life history events. In this work, we determined and compared baseline haematology and serum biochemistry between adults and chicks of three Antarctic penguin species of the genus Pygoscelis: gentoo (P. papua, Adélie (P. adeliae and chinstrap (P. antarcticus. Differences in adults among species were observed in haemoglobin and biochemical parameters such as total proteins, glucose and alkaline phosphatase activity. In addition, differences between adults and chicks in haematocrit, haemoglobin, total proteins and glucose concentration were determined. Moreover, we evaluated the electrophoretic protein profiles between adults and chicks of the genus Pygoscelis, and a conserved protein pattern was observed among species and ages in the genus. Altogether, the results suggest that biochemical and haematological differences among pygoscelids may be related to the nutritional status and energetic expenditure during breeding as well as their feeding habits and development stage.

    Some of potential causes proposed to explain the reported increase of haematological malignancies in childhood during or after the war period in several countries include depleted uranium, chemical pollution and population mixing theory. The aim of this study was to define the population of Croatian children aged 0-14 years who were potentially exposed to each of those risks during the war and to investigate any possible association between the exposure and the incidence of haematological malignancies. The authors analyzed the data reported by the Cancer Registry of Croatia during the pre-war period (1986-1990), war period (1991-1995) and post-war period (1996-1999). In the group of 10 counties potentially exposed to depleted uranium and two counties where chemical war damage occurred, no significant difference in incidence of the studied haematological malignancies was noted in comparison to pre-war period. The incidence of lymphatic leukaemia significantly increased in four counties where population mixing had occurred during the war period, supporting the 'mixing theory'. In those counties, the incidence of Hodgkin's lymphoma decreased during and after the war. In Croatia as a whole, decreases in incidence of myeloid leukaemias during war and non-Hodgkin lymphoma after the war were noted

    Mucuna pruriens (L.) DC (Fabaceae) is a climbing plant claimed in traditional medicine to possess anti-anaemic effect. The study is to investigate the effects of the hydroethanolic extract of M. pruriens (MP) on haematological profile in normal and haloperidol treated rats. MP was administered p.o. at doses of 50, 100, 200, and 400 mg/kg to groups of rats daily for 28 days. Control animals received distilled water. Rats were sacrificed on the 28th day and blood samples collected for evaluation of haematological parameters and serum iron. Another set of animals received MP p.o. at same doses but along with haloperidol (0.2 mg/kg, i.p.) daily for 4 days. Three other groups of rats received distilled water, haloperidol, and MP at 400 mg/kg alone. Haematological parameters and serum iron were determined. Extract iron content, phytochemical analysis and acute toxicity studies were also carried out. MP administered to normal rats for 28 days significantly (p Mucuna pruriens possibly possess beneficial effects in anaemic conditions especially associated with iron deficiency.

    Full Text Available Sixty growing rabbits of mixed breeds and sexes were used for 10 wk in a 4 x 3 factorial experimental design to test for the effect of different feed access times (2, 4, 6 and 24 h and different restriction durations (2, 4 and 6 wk on the performance, haematological parameters and cost benefits of growing rabbits. Data obtained were subject to a 2�way analysis of variance. Results showed significantly higher (p0.05 across the feed access time and restriction duration. White blood cell was higher in growing rabbits on 2-h feed access time for 6-wk duration of restriction while all other parameters measured for haematology were not significantly affected by the feed access time and restriction duration. Total cost of feed consumed was highest in growing rabbits maintained on 24-h feed access time. Cost of feed per kg weight gain was not significantly influenced across the feed access times and the restriction durations. It was concluded that for a reduced cost of feeding without an adverse effect on the performance and haematological profile, growing rabbits should be raised on not less than 4-h feed access time for 2-wk restriction duration.

    Argulosis hampers aquaculture production and alters the host physiology and growth. Azadirachtin is recognized as a potential antiparasitic agent against Argulus sp. The present study aimed to investigate the effect of different concentration of azadirachtin solution on haematological and serum biochemical parameters of Argulus-infested goldfish Carassius auratus. Ninety Argulus-infested goldfish were randomly divided into six equal groups. Fish of group 1-5 were treated with azadirachtin solution through bath of 1, 5, 10, 15 and 20 mg L(-1) as T1, T2, T3, T4 and T5, respectively, and group 6 was exposed to 2% DMSO solution without azadirachtin and considered as negative control T0(-). Along with six treatment groups, a positive control T0(+) of healthy goldfish free from Argulus infestation was also maintained. Parasitic mortality was evaluated after 3 days of consecutive bath treatment. After 7 days of post-treatment, the blood and serum were drawn from each of the treatment groups and haematological and serum biochemical parameters were evaluated. Total leucocyte count (TLC), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), blood glucose, total protein (TP), globulin, serum glutamate oxaloacetate transaminase (SGOT) and serum glutamate pyruvate transaminase (SGPT) were significantly (p azadirachtin have notable effects on activity of vital tissues function and physiology of the host. Argulus spp. from infested goldfish could be eliminated using bath treatment with solution of azadirachtin having concentration of 15 mg L(-1) and that also shifted haematological and serum biochemical parameters towards homeostasis.

    The aim of the present study was to evaluate the protective effect of Aloe vera against radiation and cadmium induced haematological changes in the Swiss albino mice; 6-8 weeks old animals from each of the experimental groups were sacrificed by cervical dislocation at each post treatment intervals of 1,2,4,7,14 and 28 day. After sacrificing the animals, the blood was collected by cardiac puncture in heparinized tubes for various haematological studies. The values of RBC, WBC, Haemoglobin and PCV were found to decrease up to day-14 in non drug treated groups (II,III and IV), thereafter they increased on day-28. Whereas the values decreased upto day-7 in Aloe vera treated groups (V,VI,VlI) thereafter increased tip to day-28. On the other hand, the value of MCV increased upto day- 14 in non-drug treated groups (II, III, IV) and tip to day-7 in drug treated groups (V, VI, VII), thereafter it decreased tip to day-28. After combined treatment of radiation and cadmium chloride synergistic effects were observed. The Aloe vera treated animals exhibited less severe damage as compared to non-drug treated animals at all the corresponding intervals. An early and fast recovery was noticed in Aloe vera pretreated animals. Thus, it appears that Aloe vera is potent enough to check cadmium and radiation induced haematological changes in the Swiss albino mice. (author)

    Background: Patients with haematological malignancies are often hospitalized in protective isolation until full neutrophil recovery in order to prevent infections. This descriptive pilot study evaluate the level of isolation-related distress and the use of free time in a sample of Italian onco-haematological patients who were hospitalized in protective isolation. Materials and Methods: Participants were 18 patients hospitalized in hematologic ward to receive induction therapy (n=12) or autologous stem cell transplant (n=6). They completed a self-report questionnaire before discharge. Results: Participants reported a moderate level of isolation-related distress, anxiety, and boredom: the more the anxiety and the boredom, the more the distress (r=.77; Psurfing in Internet or using PC (33.3%), and playing games or making cross-words (16.7%). Participants who reported pessimistic thinking had higher isolation-related distress (P=.004) as well as anxiety (P<.001) and boredom (P=.001). Conclusion: Haematology Units should support isolated patients in spending their time in recreational activities, allowing more contacts with immediate relatives and friends, providing free TV and Wi-Fi connection inside the room. In addition, patients should have to keep themselves physically active. Isolation-related distress could also be reduced by providing psychological support.

    The purpose of the present study was to evaluate the detection rate of genomic aberrations in haematological malignancies using oligobased array-CGH (oaCGH) analysis in combination with karyotyping and fluorescence in situ hybridization (FISH) analyses, and its feasibility in a clinical pragmatic approach. The 4x180K Cancer Cytochip array was applied in 96 patients with various haematological malignancies in a prospective setting and in 41 acute myeloid leukemia (AML) patients retrospectively. Combined use of oaCGH analysis and karyotyping improved the overall detection rate in comparison to karyotyping-alone and vice versa. In cases with normal karyotypes oaCGH analysis detected genomic aberrations in 66% (39/60) of cases. In the group of simple karyotypes oaCGH analysis extended karyotypic findings in 39% (12/31) while oaCGH analysis extended the karyotypic findings in 89% (39/44) of cases with complex karyotypes. In 7% (5/75) of cases oaCGH analysis failed in detecting the observed abnormalities by karyotyping. oaCGH analysis is a valuable asset in routine cytogenetics of haematological malignancies.

    Objective: To explore the significance of platelet parameters, including mean platelet volume, platelet count and other haematological indices, in patients of acute coronary syndrome. Methods: In this one-year retrospective cross-sectional study in 2010, a total of 631 patients were enrolled at the Cardiovascular Research Institute, Tabriz University of Medical Sciences, Iran, and classified into three groups: myocardial infarction, unstable angina, and Control. Cardiovascular risk factors such as smoking, diabetes mellitus, hyperlipidaemia and hypertension status were compared. Blood samples were collected for the measurement of platelet count, mean platelet volume and other haematological indices, including prothrombin time, partial thromoplastin time, blood group and Rh, haematocrit, haemoglobin, and erythrocyte sedimentation rate. SPSS 18 was used for statistical analysis. Results: Of the total, there were 210 (33.3%; 163 men, 47 women) with myocardial infarction whose mean age was 62.7+-14.2 years; 211 (33.3%; 110 men, 101 women) had unstable angina with a mean age of 63.5+-13.1 years and 210 (33.3%; 117 men, 90 women) health controls with a mean age of 60.6+-12.8 years. The mean platelet volume values of patients in the first two groups were significantly higher than the control group (10.14 +-1.05 fL, 9.82 +- 0.93 fL and 9.34+-1.14 fL, respectively; p< 0.001). The platelet count was detected to be significantly lower in the patients than the controls (207.92+-58.40*109/L, 220.18+-65.81*109/L, 238+-56.10*109/L, respectively, p<0.001). While blood cell count was significantly higher in those with myocardial infarction compared to the unstable angina patients and control group (P<0.001). Differences in mean values of mean platelet volume between the two patient groups was not significant, but mean values of platelet count was statistically significant between these two groups (p<0.04). Conclusion: Mean platelet volume and platelet count may be considered

    The aim of this study was to predict the probability of central venous catheter-related bloodstream infections (CRBSIs) in patients with haematologic malignancies using a modified version of the Infection Probability Score (mIPS). In order to perform a prospective, mono-centric surveillance of complications in clinical routine due to short-term central venous catheters (CVCs) in consecutive patients receiving chemotherapy from March 2013 to September 2014, IPS was calculated at CVC insertion and removal (mIPSin and mIPSex, respectively). We used the 2012 Infectious Diseases Working Party of the German Society of Haematology and Medical Oncology (AGIHO/DGHO) criteria to define CRBSI. In total, 143 patients (mean 59.5 years, 61.4 % male) with 267 triple-lumen CVCs (4044 CVC days; mean 15.1 days, range 1-60 days) were analysed. CVCs were inserted for therapy of acute leukaemia (53.2 %), multiple myeloma (24.3 %) or lymphoma (11.2 %), and 93.6 % were inserted in the jugular vein. A total of 66 CRBSI cases (24.7 %) were documented (12 definite/13 probable/41 possible). The incidence was 16.3/1000 CVC days (2.9/3.1/10.1 per 1000 CVC days for definite/probable/possible CRBSI, respectively). In CRBSI cases, the mIPSex was higher as compared to cases without CRBSI (13.1 vs. 7.1; p < 0.001). The best mIPSex cutoff for CRBSI prediction was 8 points (area under the curve (AUC) = 0.77; sensitivity = 84.9 %, specificity = 60.7 %, negative predictive value = 92.4 %). For patients with an mIPSex ≥8, the risk for a CRBSI was high (odds ratio [OR] = 5.9; p < 0.001) and even increased if, additionally, CVC had been in use for about 10 days (OR = 9.8; p < 0.001). In case other causes of infection are excluded, a mIPSex ≥8 and duration of CVC use of about 10 days predict a very high risk of CRBSI. Patients with a mIPSex <8 have a low risk of CRBSI of 8 %.

    Peptide receptor radionuclide therapy (PRRT) has become an important treatment option in the management of advanced neuroendocrine tumours. Long-lasting responses are reported for a majority of treated patients, with good tolerability and a favourable impact on quality of life. The treatment is usually limited by the cumulative absorbed dose to the kidneys, where the radiopharmaceutical is reabsorbed and retained, or by evident haematological toxicity. The aim of this study was to evaluate how renal function affects (1) absorbed dose to the kidneys, and (2) the development of haematological toxicity during PRRT treatment. The study included 51 patients with an advanced neuroendocrine tumour who received {sup 177}Lu-DOTATATE treatment during 2006 - 2011 at Sahlgrenska University Hospital in Gothenburg. An average activity of 7.5 GBq (3.5 - 8.2 GBq) was given at intervals of 6 - 8 weeks on one to five occasions. Patient baseline characteristics according to renal and bone marrow function, tumour burden and medical history including prior treatment were recorded. Renal and bone marrow function were then monitored during treatment. Renal dosimetry was performed according to the conjugate view method, and the residence time for the radiopharmaceutical in the whole body was calculated. A significant correlation between inferior renal function before treatment and higher received renal absorbed dose per administered activity was found (p < 0.01). Patients with inferior renal function also experienced a higher grade of haematological toxicity during treatment (p = 0.01). The residence time of {sup 177}Lu in the whole body (range 0.89 - 3.0 days) was correlated with grade of haematological toxicity (p = 0.04) but not with renal absorbed dose (p = 0.53). Patients with inferior renal function were exposed to higher renal absorbed dose per administered activity and developed a higher grade of haematological toxicity during {sup 177}Lu-DOTATATE treatment. The study confirms the

    To evaluate hematological parameters in African population to estimate normal reference intervals for these tests. Study Design: Cross sectional observational study. Place and Duration of Study: Department of Pathology, United Nations level 3 hospital, Nyala, Darfur from 1st Mar to 30th Dec 2014. Material and Methods: There were 396 healthy African male and female volunteers selected between 18-65 years of age, belonging to different countries. Fresh whole blood was used to measure haemoglobin (Hb) concentration, haematocrit (Hct), total red blood cell (TRBC) count, mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), platelet count, total leucocyte count (TLC) and differential white blood cells count. Data were analysed using SPSS version 19. Results: Mean Hb of study group was 13.81 +- 1.99 g/dl. Mean TLC was 5.50 +- 1.96 x 103/ul. Mean lymphocyte count was 2.58 +- 0.95. Mean platelet count was 234 +- 92 x103 /ul. Mean values for Hb Concentration, TRBC, Hct Ratio, MCV, MCH and MCHC were all higher for African Males than Females; this difference was statistically significant (p<0.05). Conclusion: This multi-national African population based study confirms the variations in haematological parameters previously described in single nation African studies. The commonly observed variations in normal adults are low RBC indices, relative neutropenia and lymphocytosis. (author)

    Horses are transported frequently and often over long distances. Transportation may represent a physiological stressor with consequential health and welfare implications. This study reports the effects of a long distance journey on immunological, clinical, haematological, inflammatory and oxidative parameters in an Experimental Group (EG) of ten horses, comparing them with six horses of similar age and breed used as a non-transported Control Group (CG). Clinical examination and blood sampling were performed twice on all horses: immediately after unloading for the EG, and at rest on the same day for the CG (day 1); at rest on the same day one week later for both groups (day 7). On day 1 EG horses showed increased heart and respiratory rates (Ptransportation induced an acute phase response impairing the cell-mediated immune response. Clinical examinations, including assessing CRT and body weight loss, and the monitoring of redox balance may be useful in evaluating the impact of extensive transport events on horses. A better understanding of the link between transportation stress, the immune system and the acute phase response is likely to inform strategies for enhancing the welfare of transported horses.

    The objective of this study was to determine the nature of the alarm for immature granulocytes appearing in haemograms from pregnant women, as detected by the immature cell information channel (IMI) of the SE-9000 automated haematology analyser. Of all tests run on pregnant women in a 4-month period (n = 698), the first 100 haemograms with immature granulocyte alarms (14.33%) were collected. Each of these samples was then stained with Wright-Giemsa stain. The following variables were also analysed: age of the mother, trimester and days of gestation, type of delivery, weight and sex of the baby, and Apgar score. Most pregnant women were in the third trimester of gestation (82%) when an alarm was noted on the IMI channel. Of the patients, 62% had normal deliveries. The most frequent complication was obstructed delivery (23%). Mean percentages by microscopic counts of band cells, metamyelocytes, and myelocytes were 2.99, 0.45, and 0.19%, respectively. There was a statistically significant correlation for all cell types between the SE-9000 and the manual count method. No association was observed between the presence of immature granulocytes and the clinical variables analysed. The SE-9000 analyser shows high sensitivity in the IMI channel for detection of immature forms.

    The present study reports the haematological and biochemical protective effect of Salipriina on Swiss albino mice exposed to gamma radiation. Swiss albino mice (8 weeks old) were administered intraperitoneally Sanepil (800 mg/kg b.wt.) prior to whole body gamma-irradiation (7.5 Gy). Radiation exposure resulted in a significant decline in different bone marrow cells (pro-and normoblasts) and blood constituents (erythrocytes, leukocytes, differential leukocyte count, haematocrit,haemoglobin and erythrocyte sedimentation rate). Pro- and normoblasts, erythrocytes, leukocytes, haematocrit and haemoglobin values showed a significant (p<0.05) decline during the first 3 days, followed by a gradual recovery starting from day 7, but normal values were not recorded until 14 days post-exposure. Treatment of mice with Spirulina also caused a significant decrease in malondialdehyde (MDA) formation in the liver, suggesting its role in protection against radiation induced membrane and cellular damage. Similarly, pretreatment of mice with Spirulina caused a significant increase in serum glutathione (GSH) level in comparison with that of irradiated animals. Results suggest that Spirulina modulate the radiation induced hematological and biochemical alterations in Swiss albino mice

    We aimed to assess the incidence of haematological neoplasms (HNs) in Castilla y León (2,5 million inhabitants) and its distribution by age, gender and histological type. The epidemiological profile based on the described variables of the 10,943 HNs diagnosed during a 10-years period was analyzed, compared with other studies. The overall age-adjusted incidence was 29.4 cases/10(5) inhabitants-year, with some geographical differences. The mean age was 67.3 years, with a turning point between the 6th-7th decades of life from which there was a very significant increase of incidence. Two relevant facts where simultaneous with advancing age: decreased lymphoid neoplasms incidence and increased low degree neoplasms incidence. Lymphoid low degree neoplasms accounted for half of the registered processes, showed the greatest preference for male and reached the mode before the rest of neoplasms. Myeloid neoplasms incidence (9.5) was higher than that reported in other European registries, specially compared to southern European countries, opposite to lymphoid neoplasms incidence (20.0). A higher myeloid neoplasms incidence and lower lymphoid one than expected was observed. The turning point of incidence is between the 6th-7th decades of life, with a preference for male that decreases with age. There is an increased incidence of HNs in the area where a higher density of potentially polluting facilities is concentrated. Copyright © 2013 Elsevier España, S.L.U. All rights reserved.

    M. Effects of sub-lethal exposures to nitrite (0 mM, 1.4 mM, and 3.0 mM) were determined during a 7-day exposure period. Plasma nitrite increased, but the internal concentration remained well below ambient levels. Extracellular nitrate rose by several mM, indicating that a large proportion of the nitrite...... taken up was converted to nitrate. Nitrite reacted with erythrocyte haemoglobin (Hb) causing methaemoglobin (metHb) to increase to 30% and nitrosylhaemoglobin (HbNO) to increase to 10% of total Hb. Both metHb and HbNO stabilised after 4 days, and functional Hb levels accordingly never fell below 60......The tolerance and effects of nitrite on ion balance and haematology were investigated in the striped snakehead, Channa striata Bloch 1793, which is an air-breathing fish with reduced gills of importance for aquaculture in South East Asia. C. striata was nitrite tolerant with a 96 h LC50 of 4.7 m...

    The use of differently processed soya bean as a major source of dietary protein was evaluated in a haematological study using broiler chickens in which groundnut cake (GNC), raw soya bean (RSB), roasted soya bean (RtSB), cooked soya bean (CSB) and soya bean oil cake (SBC) were fed on equi-protein basis. The results showed that: 1. Red blood cell (RBC) count and haemoglobin content of blood significantly (P less than 0.05) increased in chicks fed RSB relative to the other soya bean diets. Feeding differently processed soya bean significantly (P less than 0.05) influenced mean cell haemoglobin (MCH) and mean corpuscular volume (MCV) while the mean corpuscular haemoglobin concentration (MCHC) was not significantly influenced. 2. Both the total white blood cell (WBC) count and the monocytes were significantly (P less than 0.05) influenced by the dietary treatments. Chicks fed processed soya bean generally had higher number of monocytes. 3. Physical properties determined were specific gravity and erythrocyte sedimentation rate. The latter was significantly (P less than 0.05) lower in all the processed soya bean-fed chicks. 4. Minerals determined in blood were Na, K, Ca, Mg, Fe, Cu and P. Of all these, chicks fed RSB had significantly (P less than 0.01) lower levels of blood Mg and marked decrease in Ca.

    products and risk factors for bleeding in an adult population of ICU patients with haematological malignancies. METHODS: We screened all patients with acute leukaemia and myelodysplastic syndrome admitted to a university hospital ICU during 2008-2012. Bleeding in ICU was scored according to the WHO grading...... lower and upper airways and upper GI tract. Thirty-nine (59%) of the 66 patients had severe or debilitating (WHO grade 3 or 4) bleeding. The median platelet count on the day of grade 3 or 4 bleeding was 23 × 109 per litre (IQR 13-39). Nine patients (8%) died in ICU following a bleeding episode; five...... was the cause of death in four patients. The median platelet count was 20 × 109 per litre (15-48) at the time of thrombosis. The patients received a median of 6 units of red blood cells, 1 unit of fresh frozen plasma and 8 units of platelet concentrates in ICU. CONCLUSIONS: Severe and debilitating bleeding...

    Full Text Available Case summary An 11-year-old spayed female domestic shorthair cat with a history of hyperthyroidism treated with carbimazole for 7 months was presented for a check-up after a few episodes of vomiting. The cat had been receiving prednisolone at 0.5 mg/kg PO q12h for recent pancreatitis and concurrent inflammation of liver and small intestines confirmed by biopsies. Clinical examination revealed pale mucous membranes with a capillary refill time of 120 s and fibrinogen serum concentration (3.5 g/l. Morphological changes of thrombocytes in the absence of thrombocytopenia were also noted. In-saline agglutination test was positive. Abdominal radiographic and ultrasonographic examinations excluded the presence of organ abnormalities and peritoneal effusion. Blood biochemistry was unremarkable. Feline leukaemia virus and feline immunodeficiency virus tests were negative. On the basis of these findings, immune-mediated anaemia secondary to chronic carbimazole administration was suspected. Prednisolone was increased to 2 mg/kg PO q24h and carbimazole tablets were stopped. Despite close monitoring and intensive care, the cat died the same evening of admission to the hospital. Relevance and novel information This report suggests that severe haemotoxicity may occur as a sequel of chronic carbimazole administration in cats. Routine bloodwork and accurate follow-up of cats under treatment with thyrotoxic therapy may be advisable, in order to detect haematological changes before lethal complications occur.

    Plasma chemistry and haematological studies were conducted on chickens with coccidiosis. Male White Leghorn chickens, of two weeks old, were inoculated with 5 x 10(4) Eimeria tenella sporulated oocysts or with 1 x 10(6) E acervulina sporulated oocysts. Blood samples were taken four, seven and 11 days after inoculation. A wet chemistry system was applied to measure the plasma activities of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, gamma glutamyltransferase, creatine kinase, amylase and lactate dehydrogenase and the concentrations of creatine, total bilirubin, urate, total cholesterol, total protein, albumin, glucose and triglycerides. A dry chemistry system was applied to measure sodium, potassium, chloride and calcium. The number of red blood cells and packed cell volume were determined by a micro cell counter and blood pH was measured with a blood gas analyser. The erythrocyte count, packed cell volume, sodium and chloride levels in the chickens infected with E tenella were significantly (P < 0.05) lower than those of the uninfected controls. The significant decrease in blood pH of the chickens infected with E acervulina suggests malabsorption associated with duodenal lesions induced by the infection.

We aimed to analyze effects of SOT on the IBD course in a large IBD patient cohort.Clinical data from 1537 IBD patients were analyzed for patients who underwent SOT (n = 31 between July 2002 and May 2014. Sub-analyses included SOT outcome parameters, IBD activity before and after SOT, and efficacy of IBD treatment.4.74% of patients with ulcerative colitis (UC and 0.84% of patients with Crohn's disease (CD underwent SOT (p = 2.69 x 10(-6, UC vs. CD. 77.4% of patients with SOT underwent liver transplantation (LTx with tacrolimus-based immunosuppressive therapy after SOT. All LTx were due to primary sclerosing cholangitis (PSC or PSC overlap syndromes. Six patients (19.4% required renal transplantation and one patient (3.2% heart transplantation. A survival rate of 83.9% after a median follow-up period of 103 months was observed. Before SOT, 65.0% of patients were in clinical remission and 5 patients received immunosuppressive therapy (16.1%. After SOT, 61.0% of patients were in remission (p = 1.00 vs. before SOT and 29.0% required IBD-specific immunosuppressive or anti-TNF therapy (p = 0.54 vs. before SOT. 42.9% of patients with worsening of IBD after SOT were at higher risk of needing steroid therapy for increased IBD activity (p = 0.03; relative risk (RR: 10.29; 95% CI 1.26-84.06. Four patients (13.0% needed anti-TNF therapy after SOT (response rate 75%.SOT was more common in UC patients due to the higher prevalence of PSC-related liver cirrhosis in UC. Despite mainly tacrolimus-based immunosuppressive regimens, outcome of SOT and IBD was excellent in this cohort. In this SOT cohort, concomitant immunosuppressive therapy due to IBD was well tolerated.

    We identified six studies eligible for inclusion in this review; five RCTs and one NRS. Three completed RCTs (156 participants), one completed NRS (84 participants), and two ongoing RCTs. We identified one additional RCT awaiting classification. The completed studies were conducted between 1997 and 2015 and had a mean follow-up from 31 days to 2 years. One study included children receiving a HSCT (six participants), the other three studies only included adults: 218 participants with acute leukaemia receiving chemotherapy, and 16 with a haematological malignancy receiving a HSCT. The restrictive strategies varied from 70 g/L to 90 g/L. The liberal strategies also varied from 80 g/L to 120 g/L. Based on the GRADE rating methodology the overall quality of the included studies was very low to low across different outcomes. None of the included studies were free from bias for all ’Risk of bias’ domains. One of the three RCTs was discontinued early for safety concerns after recruiting only six children, all three participants in the liberal group developed veno-occlusive disease (VOD). Evidence from RCTs A restrictive RBC transfusion policy may make little or no difference to: the number of participants who died within 100 days (two trials, 95 participants (RR: 0.25, 95% CI 0.02 to 2.69, low-quality evidence); the number of participants who experienced any bleeding (two studies, 149 participants; RR:0.93, 95% CI 0.73 to 1.18, low-quality evidence), or clinically significant bleeding (two studies, 149 participants, RR: 1.03, 95% CI 0.75 to 1.43, low-quality evidence); the number of participants who required RBC transfusions (three trials; 155 participants: RR: 0.97, 95% CI 0.90 to 1.05, low-quality evidence); or the length of hospital stay (restrictive median 35.5 days (interquartile range (IQR): 31.2 to 43.8); liberal 36 days (IQR: 29.2 to 44), low-quality evidence). We are uncertain whether the restrictive RBC transfusion strategy: decreases quality of life (one trial

    Objective: To determine the frequency of portal hypertensive gastropathy (PHG) and its relation with biochemical, haematological and endoscopic findings in cirrhotic patients. Study Design: Cross-sectional analytical study. Place and Duration of Study: Jinnah Postgraduate Medical Centre, Karachi, Medical Unit-III, Ward-7, from June 2009 to December 2010. Methodology: Patients with diagnosis of cirrhosis and either undergoing screening upper gastrointestinal (GI) endoscopy or presented with acute upper GI bleeding were included in the study. Portal hypertensive gastropathy and oesophageal varices were classified using Baveno scoring system. The severity of cirrhosis was classified according to the Child-Pugh criteria. Hypersplenism was assessed by the reduction of haemoglobin, leucocytes and platelets. Results: Out of 217 patients, 148 were males (68.2%) and 69 were females (31.8%) with ages ranging from 15-85 years, (mean 48.06 years). There were 144 HCV +ve patients (66.4%), 36 HBV +ve patients (16.6%), 15 HCV/HBV co-infected patients (6.9%) and only 1 (0.5%) had co-infection of HBV/HDV. Twenty-one patients (9.7%) were classified as having cryptogenic cirrhosis. Out of 172 patients (79.27%), 56 patients (25.8%) had mild and 116 patients (53.5%) were suffering from severe PHG. Significant positive correlation was found between esophageal variceal grade and PHG (r=0.46, p < 0.001) but not with etiology (r=0.05, p=0.41) or hypersplenism (r=0.08, p=0.22). Conclusion: The frequency of PHG was 79.27% in the studied group. The grade of oesophageal varices had significant relation with PHG that is the severity of PHG increased with the grade of oesophageal varices, suggesting common pathophysiology of both entities.

    This study was aimed to investigate the role of erythrocyte, platelet and reticulocyte (RET) parameters, measured by new haematological analyser Sysmex XN and C reactive protein (CRP), for early diagnosis of sepsis during intensive care unit (ICU) stay. The study population consisted of 62 ICU patients, 21 of whom developed sepsis during ICU stay and 41 who did not. The performance for early diagnosing of sepsis was calculated as area under the curve (AUC) of receiver operating characteristics curves analysis. Compared with CRP (AUC 0.81), immature platelet fraction (IPF) (AUC 0.82) showed comparable efficiency for identifying the onset of sepsis. The association with the risk of developing sepsis during ICU stay was also assessed. One day before the onset of sepsis, a decreased of RET% was significantly associated with the risk of developing sepsis (OR=0.35, 95% CI 0.14 to 0.87), whereas an increased of IPF absolute value (IPF#) was significantly associated with the risk of developing sepsis (OR=1.13, 95% CI 1.03 to 1.24) 2 days before the onset of sepsis. The value of CRP was not predictive of sepsis at either time points. IPF# and RET% may provide valuable clinical information for predicting the risk of developing sepsis, thus allowing early management of patients before the onset of clinically evident systemic infections. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Haematological parameters and erythrocyte osmotic fragility (EOF) are commonly used as indicators of health status and erythrocyte membrane integrity. Variations in haematological parameters and EOF in late gestation and early lactation during the cold-dry (CDS), hot-dry (HDS) and rainy (RAS) seasons were studied in sixty (n = 60) Red Sokoto goats (20 goats for each season). The ambient temperatures and temperature-humidity index recorded were higher in the afternoon hours of the HDS and RAS, but lower in the morning hours of the CDS as compared with the thermoneutral zone of goats. Results revealed that the pregnant goats had significantly (P goats, higher (P goats. The EOF was significantly higher during lactation than pregnancy in the CDS and HDS. Similarly, the magnitude of the left shift in fragiligram during the CDS was more marked in pregnant compared with lactating goats. During gestation, the CDS had lower (P goats during the CDS. In conclusion, seasonal variations exist in physiology of erythrocytes of goats during the peri-partum period, with an increase in PCV and RBC, but a decrease in haemoglobin parameters in pregnant compared with lactating goats during the RAS. Erythrocyte stability and membrane integrity were higher in pregnant than lactating goats, and also higher during the CDS than the HDS and RAS, irrespective of reproductive status. This information may be useful in the design of animal breeding and is of value in animal welfare, research, diagnosis and management of haematological conditions during the peri-partum period.

The basal diet was formulated to contain 34% protein and 10% lipid and the dietary treatments were supplemented with 0.5%, 1% and 1.5% of AGEY diet. A total of 180 Common carp (10.30 ± 0.27 g) fed on experimental diets for 10 weeks. Water quality assessment for well water and pond water for rearing Cyprinus carpio in cage system conducted weekly, while some parameters including pH, EC, water temperature and DO were monitored daily during the entire periods of study. Values of total hardness, alkalinity, ammonia and nitrate for studied water samples were within normal ranges for rearing Cyprinus carpio. Mean concentration of GPT, GOT and Glucose were 104 to 170 U/L, 1371 to 3308 U/L and 34 to 63mg/dl respectively, moreover, highest levels were observed in treatments with higher concentrations of yeast in its food except for blood sugar. Slight variation in lipase enzyme were found between control and treatment groups, while levels of amylase enzyme were increased toward cages with higher levels of yeast until T1 and then decreased toward T3. Total protein levels were increased to toward higher levels of yeast in food of Cyprinus carpio fish. Haematological results showed highest levels of WBC and platelets in treatments cages than control group. Levels of RBCs and hemoglobin were highest in treatment group 1 with 0.5%of yeast than treatments higher yeast concentrations. Significant correlation was found in haematological parameters between control and treatments.

    One hundred and twenty eight, 28-weeks-old Lohmann LSL hybrid layers were used in this experiment, which lasted 12 weeks to investigate the effect of propolis supplementation on the productive performance, egg quality traits and haematological variables of laying hens. All hens were randomly classified into four equal experimental groups, eight replicates (4 birds/each). Hens in group 1 were fed on a commercial diet and considered as control group, while those in groups 2, 3 and 4 were fed on the same commercial diet and supplemented with 250, 500 and 1000 mg propolis/kg diet. The obtained results revealed that daily feed consumption/hen increased insignificantly with increasing propolis level than that of the control group. Regarding the means of egg mass and egg production rate, it was observed that the laying hens fed diets containing 250 and 1000 mg propolis/kg significantly (p hens as compared to those in the control. Concerning the haematological parameters, the results showed that the levels of total protein and globulin increased significantly with increasing propolis level, while cholesterol and liver enzymes were significantly decreased (p hens in the treated groups significantly decreased, whereas the lymphocyte count significantly increased, resulting in a decreased H/L ratio than that of the control group. Thus, it could be concluded that the supplementation of 250 mg propolis/kg diet is highly recommended to improving egg production, blood constituent and haematological parameters of the commercial laying hens.

    Sickle haemoglobin (HbS) is known to offer considerable protection against falciparum malaria. However, the mechanism of protection is not yet completely understood. In this study, we investigate how the presence of the sickle cell trait affects the haematological profile of AS persons with malaria, in comparison with similarly infected persons with HbAA. This study is based on the hypothesis that the sickle cell trait plays a protective role against malaria. Children from an endemic malaria transmission area in Yemen were enrolled in this study. Hematological parameters were estimated using manual methods, the percentage of parasite density on stained thin smear was calculated, haemoglobin genotypes were determined on paper electrophoresis, ferritin was measured using enzyme-linked immunosorbent assay, serum iron and TIBC were assayed using spectrophotometer, transferrin saturation index was calculated by dividing serum iron by TIBC and expressing the result as a percentage. Haematological parameters were compared in HbAA- and HbAS-infected children. Falciparum malaria parasitaemia was confirmed in the blood smears of 62 children, 44 (55.7%) of AA and 18 (37.5%) AS, so there was higher prevalence in HbAA children (P = 0.047). Parasite density was lower in HbAS- than HbAA-infected children (P = 0.003). Anaemia was prominent in malaria-infected children, with high proportions of moderate and severe forms in HbAA (P = 0.001). The mean levels of haemoglobin, packed cell volume, reticulocyte count, platelets count, lymphocytes, eosinophils, and serum iron were significantly lower while total leukocytes, immature granulocytes, monocytes, erythrocyte sedimentation rate, transferrin saturation, and serum ferritin were significantly higher in HbAA-infected children than HbAS-infected children. Infection with Plasmodium falciparum malaria caused more significant haematological alterations of HbAA children than HbAS. This study supports the observation that sickle cell trait

    Primary Intestinal Lymphangiectasia (PIL) is a rare disease of unknown aetiology which presents in the paediatric age group with anasarca, diarrhoea, hypoproteinaemia, lymphoedema and chylous effusions. Tuberculosis, filariasis, chest trauma, malignancies and haematological disorders usually contribute to most cases of secondary lymphangiectasia and chylous effusions. We hereby describe a case of PIL presenting with chylous effusions which remained undiagnosed for eight years.

    Text mining is a flexible technology that can be applied to numerous different tasks in biology and medicine. We present a system for extracting disease-gene associations from biomedical abstracts. The system consists of a highly efficient dictionary-based tagger for named entity recognition...... of human genes and diseases, which we combine with a scoring scheme that takes into account co-occurrences both within and between sentences. We show that this approach is able to extract half of all manually curated associations with a false positive rate of only 0.16%. Nonetheless, text mining should...... not stand alone, but be combined with other types of evidence. For this reason, we have developed the DISEASES resource, which integrates the results from text mining with manually curated disease-gene associations, cancer mutation data, and genome-wide association studies from existing databases...

    Few data are available on whether adjusting the dose of posaconazole syrup is effective in patients receiving anti-cancer chemotherapy. The aim of this prospective study was to analyse the impact of increasing the frequency of posaconazole administration on optimal plasma concentrations in adult patients with haematological malignancy. A total of 133 adult patients receiving chemotherapy for acute myeloid leukaemia or myelodysplastic syndrome who received posaconazole syrup 200 mg three times daily for fungal prophylaxis were enrolled in this study. Drug trough levels were measured by liquid chromatography-tandem mass spectrometry. In 20.2% of patients (23/114) the steady-state concentration of posaconazole was suboptimal (increased to 200 mg four times daily. On Day 15, the median posaconazole concentration was significantly increased from 368 ng/mL [interquartile range (IQR), 247-403 ng/mL] to 548 ng/mL (IQR, 424-887 ng/mL) (P = 0.0003). The median increase in posaconazole concentration was 251 ng/mL (IQR, 93-517 ng/mL). Among the patients with initially suboptimal levels, 79% achieved the optimal level unless the steady-state level was increasing the administration frequency of posaconazole syrup is effective for achieving optimal levels in patients with haematological malignancy undergoing chemotherapy.

    Clinical practice in haematological oncology often involves difficult diagnostic and treatment decisions. In this context, understanding patients' information needs and the functions that information serves for them is particularly important. We systematically reviewed qualitative and quantitative evidence on haematological oncology patients' information needs to inform how these needs can best be addressed in clinical practice. PsycINFO, Medline and CINAHL Plus electronic databases were searched for relevant empirical papers published from January 2003 to July 2016. Synthesis of the findings drew on meta-ethnography and meta-study. Most quantitative studies used a survey design and indicated that patients are largely content with the information they receive from physicians, however much or little they actually receive, although a minority of patients are not content with information. Qualitative studies suggest that a sense of being in a caring relationship with a physician allows patients to feel content with the information they have been given, whereas patients who lack such a relationship want more information. The qualitative evidence can help explain the lack of association between the amount of information received and contentment with it in the quantitative research. Trusting relationships are integral to helping patients feel that their information needs have been met. © 2017 John Wiley & Sons Ltd.

    Full Text Available Several severe complications may be associated with the use of central venous catheters (CVC. We retrospectively evaluated on a large cohort of patients the incidence of CVC-related early and late complications. From 7/99 to 12/2005, 1102 CVC have been implanted at our Institution in 881 patients with haematological malignancies (142,202 total day number of implanted CVC. Early mechanic complications were 79 (7.2% - 0.55/1,000 days/CVC. Thirty-nine episodes of early infective complications (<1 week from CVC implant occurred (3.5% - 0.3/1000 days/CVC: furthermore, 187 episodes of CVC-related sepsis (17% - 1.3/1000 days/CVC were recorded. There were 29 episodes (2.6% of symptomatic CVC-related thrombotic complications, with a median interval from CVC implant of 60 days (range 7 – 395. The rate of CVC withdrawal due to CVC-related complications was 26%. The incidence of CVC-related complications in our series is in the range reported in the literature, notwithstanding cytopenia often coexisting in haematological patients.

    This study was performed on 30 mature male albino rats to evaluate the direct effect of fractionated low doses (0.5 Gy twice weekly) gamma radiation and delayed effect (one month post-irradiation) on some haematological and immunological parameters. The rats were divided into three equal groups, Control and two whole body gamma-irradiated groups the irradiated groups were subjected to total doses of 4 and 8 Grays over a period of one and two months, respectively. The blood samples and peritoneal macrophages were taken twice from each irradiated rats at the end of their irradiation period and after one month post irradiation. Activated peritoneal macrophages in all groups showed significant decrease as compared to control group denoting that irradiation may cause receptor alteration and/or decrease in the phagocytic power of macrophages lasting for a longer time. Throughout the whole experiment there was wide variation in platelet count with no significant or minimal changes in other blood elements. Moreover, in the post irradiation group after two months irradiation, all the haematological parameters tested, except the Hct, were increased as compared to the control group. These results pointed to that the bone marrow and lymphoid organs of the animals can tolerate fractionated low dose irradiation through rapid recovery and/or compensatory stimulation. The presence of many target cells in the post irradiated group increases the red blood cell fragility

    The aim of the study was to investigate the effects of age and season on haematological parameters of donkeys at rest during the rainy and cold-dry seasons. Thirty healthy donkeys divided into three groups based on their age served as the subjects. During each season, blood sample was collected from each donkey thrice, 2 weeks apart, for haematological analysis, and the dry-bulb temperature (DBT), relative humidity (RH) and temperature-humidity index (THI) were obtained thrice each day during the experimental period using standard procedures. During the rainy season, the mean DBT (33.05 ± 0.49 °C), RH (73.63 ± 1.09 %) and THI (84.39 ± 0.71) were higher ( P donkeys were higher ( P donkeys were higher ( P < 0.05) in the rainy than in the cold-dry season. In conclusion, PCV, RBC, Hb and LYM were considerably higher in foals than yearlings or adults during the rainy season, while erythrocytic indices and platelet counts were higher in adults or yearlings than in foals in both seasons. Erythrocytic indices, PLT and N/L were higher in the rainy than the cold-dry season in adults, yearlings and foals.

    The pathogenesis of alcohol-induced osteonecrosis remains unclear. The purpose of the present study was to evaluate the morphological changes in bone marrow fat cells and the changes in the serum lipid levels in alcohol-treated rabbits. Fifteen rabbits were randomly assigned into three groups: Four rabbits intragastrically received low-dose alcohol (LDA) (15 ml/kg per day) containing 15% ethanol for 4 weeks, five rabbits received high-dose alcohol (HDA) (30 ml/kg per day) for 4 weeks and six rabbits received physiologic saline for 4 weeks as a control group. Six weeks after the initial alcohol administration, all rabbits were sacrificed. The mean size of the bone marrow fat cells in rabbits treated with HDA was significantly larger than that in the control group (P = 0.0001). Haematologically, the levels of triglycerides and free fatty acids in the rabbits treated with both low-dose and HDA were significantly higher than those in the control group (P = 0.001 for both comparisons). The results of this study are that there are lipid metabolism abnormalities, both morphologically and haematologically, after alcohol administration. Also these findings were more apparent in rabbits treated with HDA than those treated with LDA. © 2011 The Authors.

Basal diet was supplemented with 0 (control, 0.5, 1, and 2 g·kg-1 F. angulata and was randomly allocated to experimental fish of an initial average weight of 7.45 ± 0.02 g. After 8 weeks of experiment, the fish supplemented with F. angulata extract showed increased but non-significant (P > 0.05 growth performance. No significant differences were found between trial control groups in haematological indices such as red blood cell count, haematocrit, and haemoglobin, but there was a significant increase in white blood cells, lymphocytes, neutrophils and monocytes in the F. angulata extract groups (P < 0.05. Also, there were significant differences between the fish supplemented with dietary F. angulata extract and the control group regarding immunological indices, including immunoglobulin M, lysozyme, and classical and alternative complement pathway (P < 0.05. These findings suggest that the administration of F. angulata extract has a positive effect on the immunological indices and the immune system activity in rainbow trout fingerling.

  20. Perspectives of patients with haematological cancer on how clinicians meet their information needs: "Managing" information versus "giving" it.

    Practitioners treating patients with haematological cancers have extensive clinical information available to give to patients, and patients need to be informed. However, many patients want to be protected from having information that is too detailed or threatening. To illuminate how practitioners can address this dilemma and help patients feel appropriately informed, we explored patients' experience of feeling informed or uninformed. Semi-structured interviews were conducted with 20 patients who had been diagnosed with haematological cancer and had recently received results from clinical investigations or from evaluations of treatment response. Inductive and interpretive analysis of the transcribed audio-recorded interviews drew on constant comparison. Patients described the need for practitioners carefully to manage the information that they provided, and many felt alarmed by information that they did not experience as having been managed for them. A few patients who had difficulty trusting practitioners were not content with the information provided. These findings can be understood using attachment theory, whereby practitioners' careful management of information demonstrates their care for patients, and patients' trust in the practitioner enables them to feel informed. It follows that, when patients do not feel informed, the solution will not necessarily be more information but might be to help patients feel more secure in a caring clinical relationship.

    Owens, C

    2012-02-01

    BACKGROUND: Overall survival in paediatric cancer has improved significantly over the past 20 years. Treatment strategies have been intensified, and supportive care has made substantial advances. Historically, paediatric oncology patients admitted to an intensive care unit (ICU) have had extremely poor outcomes. METHODS: We conducted a retrospective cohort study over a 3-year period in a single centre to evaluate the outcomes for this particularly vulnerable group of patients admitted to a paediatric ICU. RESULTS: Fifty-five patients were admitted a total of 66 times to the ICU during the study period. The mortality rate of this group was 23% compared with an overall ICU mortality rate of 5%. 11\\/15 patients who died had an underlying haematological malignancy. Twenty-eight percent of children with organism-identified sepsis died. CONCLUSIONS: While mortality rates for paediatric oncology patients admitted to a ICU have improved, they are still substantial. Those with a haematological malignancy or admitted with sepsis are most at risk.

    Hericium erinaceus is a culinary-medicinal mushroom and has a long history of usage in traditional Chinese medicine as a tonic for stomach disorders, ulcers and gastrointestinal ailments. The present investigation was aimed to evaluate the potential toxic effects of the aqueous extract from the fruiting bodies of H. erinaceus in rats by a sub-chronic oral toxicity study. In this sub-chronic toxicity study, rats were orally administered with the aqueous extract of H. erinaceus (HEAE) at doses of 250, 500 and 1000mg/kg body weight (b.w.) for 90 days. Body weights were recorded on a weekly basis and general behavioural changes were observed. The blood samples were subjected to haematological, biochemical, serum electrolyte, and antioxidant enzyme estimations. The rats were sacrificed and organs were processed and examined for histopathological changes. No mortality or morbidity was observed in all the treated and control rats. The results showed that the oral administration of HEAE daily at three different doses for 90 days had no adverse effect on the general behaviour, body weight, haematology, clinical biochemistry, and relative organ weights. Histopathological examination at the end of the study showed normal architecture except for few non-treatment related histopathological changes observed in liver, heart and spleen. The results of this sub-chronic toxicity study provides evidence that oral administration of HEAE is safe up to 1000mg/kg and H. erinaceus consumption is relatively non-toxic.

    2011-10-01

    Full Text Available The aim of this review article is to review the pharmacology, pharmacokinetics, efficacy and safety of everolimus. Primary literature was obtained via MEDLINE. Studies and abstracts evaluating everolimus in solid organ transplantation were considered for evaluation. English-language studies and abstracts only were selected for inclusion. Everolimus, a proliferation signal inhibitor that prevents growth factor-induced cell proliferation, is effective in reducing the incidence of acute rejection in solid organ transplantation. This agent is also useful in reducing cyclosporine-related nephrotoxicity. Everolimus directly inhibits vascular remodelling and intimal thickening, which are often associated with chronic rejection. Clinical trials have shown that everolimus is generally safe. The most commonly reported adverse events were haematologic effects and hyperlipidaemia. Everolimus is the second proliferation signal inhibitor to be proven effective in preventing acute rejection in solid organ transplant recipients. However, its exact role in the transplant immunosuppressive armamentarium is still unknown.

    Radioimmunotherapy is based on the use of radioactive agents (iodine 131, yttrium 90), murine-derived monoclonal antibodies and specific tumour-related membrane antigens. This new treatment modality was applied in 800 patients with different types of malignant tumours which had not responded to traditional therapy. Among the haematologic tumours, the most promising results were obtained in B phenotype non-Hodgkin lymphoma. More modest results were obtained for solid tumours although good results were observed after intraperitoneal administration in patients with cancer of the ovary. The main side effects are acute reversible anaphylactic shock, haematologic toxicity and development of anti-murine human antibodies. Several methods are currently under study to increase irradiation dose delivered at the tumoural site since less than 1% of the injected radioactive dose is absorbed by tumoural cells. Several clinical studies are to be conducted in France, particularly for malignant non-Hodgkin lymphoma and cancer of the ovary. (authors). 31 refs

    Between 30 and 50% of febrile neutropenic episodes are accounted for by infection. C-reactive protein (CRP) is a nonspecific parameter for infection and inflammation but might be employed as a trigger for diagnosis. The aim of the study was to evaluate whether {sup 18}F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT can be used to detect inflammatory foci in neutropenic patients with elevated CRP and whether it helps to direct treatment. Twenty-eight consecutive patients with neutropenia as a result of intensive chemotherapy for haematological malignancies or myeloablative therapy for haematopoietic stem cell transplantation were prospectively included. {sup 18}F-FDG PET/CT was added to the regular diagnostic workup once the CRP level rose above 50 mg/l. Pathological FDG uptake was found in 26 of 28 cases despite peripheral neutrophil counts less than 0.1 x 10{sup -9}/l in 26 patients: in the digestive tract in 18 cases, around the tract of the central venous catheter (CVC) in 9 and in the lungs in 7 cases. FDG uptake in the CVC tract was associated with coagulase-negative staphylococcal bacteraemia (p < 0.001) and deep venous thrombosis (p = 0.002). The number of patients having Streptococcus mitis bacteraemia appeared to be higher in patients with grade 3 oesophageal FDG uptake (p = 0.08). Pulmonary FDG uptake was associated with the presence of invasive fungal disease (p = 0.04). {sup 18}F-FDG PET/CT scanning during chemotherapy-induced febrile neutropenia and increased CRP is able to detect localized foci of infection and inflammation despite the absence of circulating neutrophils. Besides its potential role in detecting CVC-related infection during febrile neutropenia, the high negative predictive value of {sup 18}F-FDG PET/CT is important for avoiding unnecessary diagnostic tests and therapy.

    Objective: To determine any significant correlation between the routine haematological parameters of maternal blood and umbilical cord blood of their respective newborns. Study Design: Cross sectional study. Place and Duration of Study: The study was conducted at four public and private hospitals of Karachi including Sindh Government Qatar Hospital, Sindh Government Hospital, Liaquatabad, Ziauddin University Hospital and Chinniot Maternity and Child Hospital, respectively from July 2006 to April 2008. Methodology: Three milliliters venous blood was collected in EDTA containing tube for complete blood count of mothers before delivery. Five milliliters cord blood was collected from the umbilical cord of the babies immediately after delivery by clamping and cutting the babies' end of the cord. For haematological parameters a standard coultergram was done including haemoglobin, RBCs count, haematocrit (HCT), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), white blood cell count, differential leukocyte count and platelet count. Pearson's correlation co-efficient was used to determine an association between the maternal and cord blood parameters. Results: A total of 404 maternal and umbilical cord blood samples were analyzed. All the blood parameters including haemoglobin, RBCs count, HCT, MCV, MCH, white blood cell count, differential leukocyte count and platelet count were found to be high in cord blood as compared to the maternal blood, but they showed a very weak to negligible correlation. Mean Corpuscular Haemoglobin Concentration (MCHC), showed a moderate correlation. Conclusion: Routine haematological parameters of newborns are independent of maternal routine haematological parameters. (author)

    Full Text Available Abstract: Malaria remains a major cause of morbidity and mortality in India. Plasmodium falciparum remains the main culprit although cases with vivax malaria are on the rise. Severe malaria as defined by the WHO criteria has high rate of complications and mortality. In our study we recruited microscopy positive falciparum and vivax malaria patients. Haematological and biochemical laboratory investigations were carried out in recruited patients. Both parameters were found to be significantly derailed in falciparum cases as compared to vivax. A direct correlation has been observed between kidney function tests (serum creatinine,serum urea and direct bilirubin levels across all cases of malaria. Hence these parameters can be used to identify and monitor the progress of cases of severe malaria as significant proportion of patients fulfilled the criteria of severe malaria in the cohort.

    2016-01-01

    The Fifth European Conference on Infections in Leukaemia (ECIL-5) convened a meeting to establish evidence-based recommendations for using tests to diagnose Pneumocystis jirovecii pneumonia (PCP) in adult patients with haematological malignancies. Immunofluorescence assays are recommended...... a positive test result may indicate other fungal infections. Genotyping using multilocus sequence markers can be used to investigate suspected outbreaks ( A-II: ). The routine detection of dihydropteroate synthase mutations in cases of treatment failure is not recommended ( B-II: ) since these mutations do...... not affect response to high-dose co-trimoxazole. The clinical utility of these diagnostic tests for the early management of PCP should be further assessed in prospective, randomized interventional studies....

    Burnout is a professional syndrome associated with stress caused by overwork. Our aim was to calculate the prevalence of burnout and stress on medical residents of Oncology, Haematology and Radiotherapy in Portugal, as well as to determine predictors of burnout and stress. An anonymous questionnaire was applied (n = 118). Statistical analysis consisted of a descriptive and inferential analysis. The prevalence of burnout and stress was calculated to be 45.2 and 50%, respectively. The dimensions that generated higher levels of stress were 'dealing with patients' and 'overwork'. Burnout was directly related with stress dimension 'overwork'. The prevalence of burnout in Portuguese oncological residents is high as in other European countries and in the U.S. Therefore, interventional strategies can be designed.

    PURPOSE: Traditionally, medical personnel have undertaken bone marrow (BM) examination. However, specially trained nurses in advanced practice roles are increasingly undertaking this role. This paper presents the findings from an audit of BM examinations undertaken by an advanced nurse practitioner (ANP) at a regional haematology specialist centre. METHODS: The audit evaluated the quality of BM examinations performed by the ANP over the past two years (September 2007-September 2009). Over the two year period, 324 BM examinations were performed at the centre of which 156 (48.1%) were performed by the ANP. A random sample of 30 BM examinations undertaken by the ANP were analysed by the consultant haematologist. RESULTS: All 30 BM examinations undertaken by the ANP were sufficient for diagnosis. CONCLUSIONS: The ANP is capable and competent to obtain BM samples which are of a sufficient quality to permit diagnosis.

    Hyperuricaemia and gout are closely related, but hyperuricaemia is an independent risk factor for endothelial damage, autoinflammation and haemodynamic abnormalities. Milk, generally known as a 'purine-free diet', is an essential protein source for patients suffering from hyperuricaemia and gout. As milk still contains different purine ribonucleotides, the new product, depurinized milk, almost free of purine nucleotides and uric acid, was produced. The potential effect of depurinized milk diet on serum uric acid (SUA) level, lipid parameters and blood haematological parameters was explored in rats after 72 h and 15 days, in relation to standard laboratory chow or the untreated milk diet. The beneficial effect on SUA was achieved when depurinized milk draught was given instead of standard chow for 72 h [28.39 ± 4.76 μm; p draughts enhanced haemoglobin concentration (p draught may meet the demand of healthy dairy product for population under hyperuricaemic risk. © 2011 Blackwell Verlag GmbH.

    Full Text Available The effects of dietary supplementation of selenium (Se, iodine (I, and a combination of both on the blood haematology, serum free thyroxine (FT4 and free triiodothyronine (FT3 hormones and glutathione peroxidase enzyme (GSH-Px activity were examined on twenty four (7 to 8 months old, 22±1.17 kg live weight Kacang crossbred male goats. Animals were randomly assigned to four dietary treatments (6 animals in each group. Throughout 100 d of feeding trial, the animals of control group (CON received a basal diet, while the other three groups were offered basal diet supplemented with 0.6 mg/kg diet DM Se (SS, or 0.6 mg/kg diet DM I (PI, or a combination of both Se and I, each at 0.6 mg/kg diet DM (SSPI. The haematological attributes which are haemoglobin (Hb, red blood cell (RBC, packed cell volume (PCV, mean cell volume (MCV, white blood cells (WBC, band neutrophils (B Neut, segmented neutrophils (S Neut, lymphocytes (Lymph, monocytes (Mono, eosinophils (Eosin and basophils (Baso were similar among the four treatment groups, while serum levels of Se and I increased significantly (p<0.05 in the supplemented groups. The combined dietary supplementation of Se and I (SSPI significantly increased serum FT3 in the supplemented animals. Serum GSH-Px activity increased significantly in the animals of SS and SSPI groups. It is concluded that the dietary supplementation of inorganic Se and I at a level of 0.6 mg/kg DM increased serum Se and I concentration, FT3 hormone and GSH-Px activity of Kacang crossbred male goats.

    Online educational resources are criticized as being teacher-centred, failing to address learner's needs. Needs assessments are an important precursor to inform curriculum development, but these are often overlooked or skipped by developers of online educational resources due to cumbersome measurement tools. Novel methods are required to identify perceived and unperceived learning needs to allow targeted development of learner-centred curricula. To evaluate the feasibility of performing a novel technique dubbed the Massive Online Needs Assessment (MONA) for the purpose of emergency haematology online educational curricular planning, within an online learning community (affiliated with the Free Open Access Medical education movement). An online survey was launched on CanadiEM.org using an embedded Google Forms survey. Participants were recruited using the study website and a social media campaign (utilizing Twitter, Facebook, Blogs, and a poster) targeting a specific online community. Web analytics were used to monitor participation rates in addition to survey responses. The survey was open from 20 September to 10 December 2016 and received 198 complete responses representing 6 medical specialties from 21 countries. Most survey respondents identified themselves as staff physicians (n = 109) and medical trainees (n = 75). We identified 17 high-priority perceived needs, 17 prompted needs, and 10 topics with unperceived needs through our MONA process. A MONA is a feasible, novel method for collecting data on perceived, prompted, and unperceived learning needs to inform an online emergency haematology educational blog. This methodology could be useful to the developers of other online education resources.

    Malnutrition has been reported in the literature to be adversely associated with outcomes in paediatric malignancies. Our objective in this paper was to evaluate malnutrition as a potential predictor for adverse outcomes in febrile neutropenia associated with haematological malignancies. A prospective observational study was performed in a tertiary care teaching hospital of Kolkata, India. Forty-eight participants, suffering from haematological malignancy, were included. Participants were included if they experienced at least one episode of febrile neutropenia. For children aged malnutrition, while body mass index for age was used in children ≥5 years. A total of 162 episodes of febrile neutropenia were studied. Thirty patients (30/48, 62.5%) included in the study had malnutrition. In bivariate analyses at patient level, there is a strong association between malnutrition and death (odds ratio (OR) 7.286, 95% confidence interval (CI) 0.838-63.345, one-tailed P = 0.044), and life-threatening complications show a moderate trend towards significance (OR 3.333, 95% CI 0.791-14.052, one-tailed P = 0.084). Survival functions were significantly different between malnourished and non-malnourished children (log rank test χ(2)  = 4.609, degree of freedom = 1, P = 0.032). Wasting was associated with life-threatening complications in children aged malnutrition was not. Malnutrition may be a potential predictor of mortality in febrile neutropenia. © 2016 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

    Full Text Available The Society for Paediatric Oncology and Haematology (GPOH and the corresponding Competence Network Paediatric Oncology and Haematology conduct various clinical trials. The comprehensive analysis requires reliable identification of the recruited patients. Therefore, a personal identifier (PID generator is used to assign unambiguous, pseudonymous, non-reversible PIDs to participants in those trials. We tested the matching algorithm of the PID generator using a configuration specific to the GPOH. False data was used to verify the correct processing of PID requests (functionality tests, while test data was used to evaluate the matching outcome. We also assigned PIDs to more than 44,000 data records from the German Childhood Cancer Registry (GCCR and assessed the status of the associated patient list which contains the PIDs, partly encrypted data items and information on the PID generation process for each data record. All the functionality tests showed the expected results. Neither 14,915 test data records nor the GCCR data records yielded any homonyms. Six synonyms were found in the test data, due to erroneous birth dates, and 22 synonyms were found when the GCCR data was run against the actual patient list of 2579 records. In the resulting patient list of 45,693 entries, duplicate record submissions were found for about 7% of all listed patients, while more frequent submissions occurred in less than 1% of cases. The synonym error rate depends mainly on the quality of the input data and on the frequency of multiple submissions. Depending on the requirements on maximally tolerable synonym and homonym error rates, additional measures for securing input data quality might be necessary. The results demonstrate that the PID generator is an appropriate tool for reliably identifying trial participants in medical research networks.

    Full Text Available The indiscriminate use of pesticide is a treat to non-target organisms. This study evaluates the haematological and biochemical changes induced by inhalation of local Nigerian dichlorvos insecticide on rats. The rats were randomly assigned to a control group which received only food and water and a test group which, in addition to food and water, was exposed to the pesticide for a period of 4 h daily for 28 days, after which exposure was discontinued for seven days. Five animals were sacrificed from each group on days 1, 7, 14, 21, 28 and 35, and blood was collected by cardiac puncture for haematological, biochemical and antioxidant analysis. Results obtained showed lowered values of red blood cell count (RBC, packed cell volume (PCV, haemoglobin, mean cell haemoglobin (MCH and mean cell haemoglobin concentration (MCHC (p < 0.05 with increased white blood cell count (WBC and platelet counts after day 14 when compared to the control group. Liver enzymes aspartate amino transaminase (AST and alanine amino transaminase (ALT were higher in the exposed rats compared to the control group (p < 0.05. Urea and creatinine concentrations increased significantly after day 1 and at day 28, while superoxide dismutase (SOD, gluthathione (GSH and catalase (CAT activity increased significantly compared to the control after day 1, day 14 and day 21, respectively. The RBC, PCV and haemoglobin values of all exposed rats were restored to normal following withdrawal of the pesticide, though AST, ALT, urea, creatinine and, glutathione values remained significantly high compared to the control. Inhalation of the local insecticide is toxic to the blood, liver and kidney of laboratory rats and may be deleterious to human health following long-term exposure.

    Full Text Available An experiment was conducted to evaluate the effect of replacing fish meal with grasshopper meal on haematology, blood chemistry and carcass characteristics of growing rabbits. Forty rabbits of mixed breeds, aged 6-10 weeks, were randomly assigned to the dietary treatments in a complete randomized design with eight rabbits per treatment. The rabbits were fed with diets containing 0, 1.25, 2.50, 3.75 and 5% grasshopper meal in diets designated as T1 (control, T2, T3, T4 and T5, respectively. The experimental diets and clean drinking water were supplied ad libitum throughout the experimental period of nine weeks. At the end of the feeding trial, three rabbits per treatment were slaughtered for carcass evaluation, while blood samples were collected for analysis. The result of the experiment showed significant differences (P0.05 on haemoglobin and mean corpuscular haemoglobin concentration (MCHC. The results also revealed significant differences (P0.05 on serum albumin and total protein. The results of carcass characteristics showed significant differences among treatments (P<0.05 for slaughter weight, carcass weight, dressing percentage, skin pelt, tail, feet and abdominal fat. The slaughter weight and carcass weight were better in groups receiving 2.5% grass hopper meal (50% fish meal replacement. From the results, it can be concluded that inclusion of 2.50% grasshopper meal as a replacement for fish meal (50% replacement has no adverse effects on the haematological parameters, serum biochemistry and carcass characteristics of rabbits.

    To assess whether measuring the solid portion of adenocarcinomas appearing as part-solid ground-glass nodules (GGNs) can predict a patient's prognosis accurately and how the prognosis corresponds to that of solid nodules. 501 patients (solid nodule group, 304; part-solid GGN group, 197) underwent curative surgery for stage I adenocarcinomas. Maximal diameters of the whole lesion including ground-glass opacities (D{sub whole}) and solid components only (D{sub solid}) were measured on CT. Disease-free survival (DFS) and overall survival (OS) were calculated from the date of surgery. D{sub solid} was a significant prognostic factor in the part-solid GGN group, while D{sub whole} was not. Part-solid GGNs with D{sub solid} ≤2 cm showed significantly better DFS (P = 0.016) and OS (P = 0.004) than solid nodules; however, those with D{sub solid} >2 cm did not show a significant difference. Hazard ratio (HR) for increase in D{sub solid} was significantly greater in part-solid GGNs than in solid nodules (P = 0.009). For OS, HR for increase in D{sub solid} was greater in part-solid GGNs than in solid nodule, which was marginally not significant (P = 0.060). D{sub solid} was better than D{sub whole} for prognosis prediction of adenocarcinomas appearing as part-solid GGNs. In addition, the influence of D{sub solid} on prognosis in the part-solid GGN group was greater than in the solid nodule group. (orig.)

    In France, advance directives are favourably perceived by most of the population, although the drafting rate is low. This ambivalence is challenging because advance directives are meant to promote the autonomy and freedom of choice of patients. The purpose of this study was to analyse the content of advance directives written by patients suffering from malignant haemopathies to better understand how patients put them into practice. These could be relevant as early as the initial diagnosis of haematological malignancies because of the uncertain course of the disease. This was a multicentre, qualitative, descriptive study. The advance directives written by patients with malignant haemopathies treated in one of the six French hospital departments were included in the study from 01/06/2008 to 15/04/2016. A thematic analysis of the advance directives was performed by two researchers: a senior haematologist and a research assistant. The median age of the patients was 69. Most were women (sex ratio: 0.59), living as a couple (57%), with lymphoid pathologies (66%), who were still alive two years after the instructions were written (63%) and had nominated a health care proxy (88.6%). Free texts (62.9%) were richer in content than pre-defined forms. The advance directives were used in three ways: for a purely legal purpose, to focus on medical treatments or actions, or to communicate a message to the family. Three main themes emerged: (1) refusal of medical treatment (100%), in which patients express refusal of life-sustaining care (97.1%). The actual treatments or the moment when they should be limited or stopped were not always mentioned in detail. (2) A desire for effective pain relief to avoid suffering (57.1%) and (3) messages for their family (34.3%), such as funeral arrangements (17.1%) and messages of love or trust (14.3%). Patients who write advance directives are not necessarily at the end of their lives. Their content mainly conveys treatment wishes, although

    To determine the prevalence of peripheral haematological abnormalities in children receiving cotrimoxazole prophylaxis. An outpatient hospital based cross sectional study. The study was conducted at two tertiary peadiatric HIV clinics that offer comprehensive care to children living with HIV. 202 HIV infected, antiretroviral therapy naive children aged between 3 months and 12 years who were receiving cotrimoxazole prophylaxis for at least 1 month with more than95% adherence to prophylaxis were included. Haematological abnormalities on full blood count and peripheral film. The prevalence of anaemia was 62% with normocytic normochromic anaemia being the most frequent type (45%). The commonest red blood cell abnormality was rouleaux formation on the peripheral film. Monocytosis occurred in 62%, leucopaenia in 39%, eosinophilia in 34%, neutropaenia in 18% and lymphopaenia in 10% of the children. This study showed a high prevalence ofhaematological abnormalities in HIV infected children on cotrimoxazole prophylaxis. It emphasizes the need for evaluation for anaemia and its management in children on cotrimoxazole prophylaxis.

    This study investigated the effect of Ramadan on the haematological and steroid module of the Athletes Biological Passport (ABP) of the World Anti-Doping Agency (WADA). Nine healthy physically active subjects were tested in the morning and afternoon for two days before and three days during Ramadan. Sample collection and all analyses were performed according to WADA technical documents. Although there were significant changes in the haemoglobin concentration during Ramadan, especially during the first fasting week, none of the subjects in this study exceeded the individually calculated thresholds of the ABP. No significant effects on testosterone/epitestosterone (T/E) ratio were observed but only the afternoon specific gravity (SG) of the urine was elevated. Thus, when urinary steroid concentrations are required, SG corrections need to be performed. The haematological and the steroid module of the ABP can be reliably applied during Ramadan as the observed changes are only marginal. Copyright © 2015 John Wiley & Sons, Ltd.

    2007-01-01

    Objective: To determine whether dynamic contrast-enhanced MR (DCE-MRI) can successfully predict the status of diffusely abnormal bone marrow, and so obviate some bone marrow biopsies done for this indication. Methods: DCE-MRI was performed in 25 patients with proven or known haematological malignancies. Time-signal intensity curves (TIC) analysis was generated from the region of the iliac crest corresponding to the planned biopsy site. Enhancement characteristics were analyzed, including peak enhance ratio (PER), maximum slope (Slope max ), time to peak (TTP), and mean time (MT). The parameters of the marrow histology included cellularity and tumour fraction (TF). Results: The median of PER, Slope max , TTP, and MT in bone marrow with haematological malignancies were 0.27, 0.21 s -1 , 79.08 s and 84.43 s, respectively. The median of DCE-MR variation in bone marrow for hypo-, normal, and hyper-, cellularity groups were PER (0.29, 0.24, 1.15), Slope max (0.20 s -1 , 0.21 s -1 1.28 s -1 ), TTP (96.67 s, 83.49 s, 25.52 s), MT(77.52 s, 86.25 s, 84.34 s), respectively. The median of PER, Slope max , TTP, and MT in bone marrow for the tumor recurrence group and the remission group were 0.32, 0.28 s -1 , 68.66 s, 84.34 s, and 0.20, 0.20 s -1 , 85.85 s, 84.52 s, respectively. There was significant difference for mean PER value between the tumor recurrence group and the remission group (P = 0.02). But there were no significant difference for mean S1ope max , TFP, and MT values between the tumor recurrence group and the remission group (P>0.05). A positive correlation was found between PER and cellularity (r=0.564, P=0.003), between S1ope max and cellularity (r=0.478, P=0.016), between MT and cellularity (r=0.186). A negative correlation was found between TTP and cellularity (r=-0.222). A positive correlation was found between PER and TF (r=0.561, P=0.004), between S1ope max and TF(r=0.318, P=0.121), between MT and TF (r=0.207, P>0.05). A negative correlation was found

    Background: Despite reduction in ld mortality during last decade, lower respiratory tract infection (LRTI) remained number one killer of under-five. The current study aimed to assess the association of haematological and radiological findings with clinical outcome in hospitalized children 2-36 months old with severe LRTI. Methods: In the current cross sectional study, 581 children 2-36 months old with severe LRTI were enrolled and followed at the Children Hospital, Islamabad, between 2011 and 2014. At the time of enrolment, complete history of present illness, anthropometric measurements, blood sample and chest radiograph were obtained. The primary outcome was either early clinical response (within 72 hours) or delayed clinical response (>72 hours). Multivariable logistic regression was performed to examine the association between haematological and radiological findings with clinical outcome, adjusted for potential confounding factors. Results: Of 581 enrolled children, 292 (50.3 percent) children had early, and 289 (49.7 percent) had delayed clinical response. The multivariable logistic regression showed that leucocytosis (OR 1.79, 95 percent CI 1.15-2.79), neutrophilia (OR 1.91, 95 percent CI 1.29-2.84), radiological interstitial pneumonia (OR 2.49, 95 percent CI 1.70-3.64), and lobar consolidation (OR 6.00, 95 percent CI 2.41-14.96) were significantly associated with delayed clinical response, after adjusted for potential confounding factors. Conclusions: Delayed clinical response was significantly associated with abnormal haematological and radiological findings at the time of admission in children 2-36 months old with severe LRTI. Haematological and radiological findings at the time of presentation are useful for predicting delayed clinical response in children 2-36 months old with severe LRTI. (author)

    Nocturnal rodents should be assessed at an appropriate time of day, which leads to a challenge in identifying an adequate environmental light which allows animal visualisation without perturbing physiological homeostasis. Thus, we analysed the influence of high wavelength and low intensity light during dark period on physical exercise and biochemical and haematological parameters of nocturnal rats. We submitted 80 animals to an exhaustive exercise at individualised intensity under two different illuminations during dark period. Red light (> 600 nm; sports performance experiments.

    Breed, sex and age effects on haematological and biochemical variables were investigated in 24 labrador retriever and 25 miniature schnauzer dogs during the first year of life. Blood samples were taken regularly between weeks 8 and 52. White blood cell and red blood cell counts, haemoglobin concentration, haematocrit, mean cell volume, mean cell haemoglobin, mean cell haemoglobin concentration, platelet count as well as total protein, albumin, calcium, phosphate, alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, glutamate dehydrogenase, total cholesterol, triglycerides, creatine and urea were evaluated. For all haematological and biochemical parameters, there were significant effects of age on test results. Statistically significant effects for breed and the breed×age interaction on test results were observed for most of the parameters with the exception of haemoglobin. Variations in test results illustrate growth related alterations in body tissue and metabolism leading to dynamic and marked changes in haematological and biochemical parameters, which have to be considered for the interpretation of clinical data obtained from dogs in the first year of life.

  16. Association of high mobility group BOX-1 and receptor for advanced glycation endproducts with clinicopathological features of haematological malignancies: a systematic review

    Full Text Available High-mobility group box 1 (HMGB1 is a versatile protein with nuclear and extracellular functions. In the extracellular milieu, HMGB1 binds to several receptors, notably the receptor for advanced glycation end-products (RAGE. The expressions of HMGB1 and RAGE have been described in a variety of cancers. However, the clinical values of HMGB1 and RAGE in haematological malignancies have yet to be evaluated. A systematic search through PubMed and the Web of Science for articles discussing the role of HMGB1 and RAGE in haematological malignancies produced 15 articles. Overexpression of HMGB1 was reported to be associated with malignancy and, in certain studies, poor prognosis and tumour aggressiveness. Only one included study investigated the clinical value of RAGE, in which no significant difference was found between expression of RAGE in CLL neoplastic cells and nonmalignant controls. The discussed associations of HMGB1 and RAGE with clinicopathological characteristics of patients with haematological malignancies warrants further investigation into the prognostic and diagnostic value of both of these molecules.

    Rash and oral mucositis are major non-haematological adverse events (AEs) of docetaxel, in addition to fatigue, nausea, vomiting and diarrhoea, which restrict the use of the drug in cancer therapy. Alpha-1-acid glycoprotein (AAG) is an acute phase reactant glycoprotein and is a primary carrier of docetaxel in the blood. Docetaxel has extensive binding (>98%) to plasma proteins such as AAG, lipoproteins and albumin. To study the association between plasma AAG level and non-haematological AEs of docetaxel in Malaysian breast cancer patients of three major ethnic groups (Malays, Chinese and Indians). One hundred and twenty Malaysian breast cancer patients receiving docetaxel as single agent chemotherapy were investigated for AAG plasma level using enzyme-linked immunosorbent assay technique. Toxicity assessment was determined using Common Terminology Criteria of Adverse Events v4.0. The association between AAG and toxicity were then established. There was interethnic variation of plasma AAG level; it was 182 ± 85 mg/dl in Chinese, 237 ± 94 mg/dl in Malays and 240 ± 83 mg/dl in Indians. It was found that low plasma levels of AAG were significantly associated with oral mucositis and rash. This study proposes plasma AAG as a potential predictive biomarker of docetaxel non-haematological AEs namely oral mucositis and rash.

    Full Text Available To find out the efficacy and effect of artemisinin derivatives on haematological indices, C57BL/6J mice were challenged with Plasmodium falciparum and treated with therapeutic doses of AS, AE, and AL. Course of infection was studied in the infected and treated groups up to day 42. Peak level of parasitaemia (38% was observed on day 11 in infected group. Haematological indices indicated significant (P0.05 in all drug-treated groups. Percent of peak parasitaemia was much reduced in AL- (3.2% on day 3 treated group in comparison with AE- (2.4% on day 4 and AS- (4% on day 2 treated groups. Parasites were completely cleared on day 6 in AS group, day 5 in AE group, and day 4 in AL group. Hence, our results strongly support that combination therapy has high efficacy rates than monotherapy. No adverse effects were observed on haematological parameters when animals were treated with therapeutic dosages.

    This study aim to evaluate protective role of Liv.52 against radiation and cadmium induced haematological changes in the Swiss Albino Mice. The animals were exposed with 3.0 and 6.0 Gy of gamma rays with or without Cadmium Chloride treatment. In the drug treated groups. The liv-52 was given seven days prior to irradiation or Cadmium Chloride treatment The animals from the entire experimental group were sacrificed by cervical dislocation at post treatment intervals of 1, 2, 4, 7, 14 and 28 days. The value of red blood cells (RBC), white blood cell (WBC), Haemoglobin (Hb), packed cell volume (PCV), mean cell volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), different leucocytes counts (DLC), SGOT and SGPT were estimated. The values of RBC, WBC, Hb and PCV were found to decrease in all the groups as compared to normal group, but the decrease in these values was lesser in Liv.52 treated groups (V to VII) as compared to non-drug treated groups (II to IV). The values of MCV were also found to decrease but the difference from normal value was significant at previous intervals and it was significant on later intervals. The values of MCH increased in all the groups as compared with normal group after 1, 2, 4, 7, 14 and 28 days of post-treatment intervals. The increase in the values of MCH was lesser in Liv.52 treated groups (V to VII) as compared to non-drug treated groups (II to IV). Besides this values of MCHC increased in all the groups at various intervals but the values were lower in the Liv.52 treated groups (V to VII) as compared to non-drug treated groups (II to IV). The difference from the normal was non-significant in all the groups. The values of lymphocytes declined up to day-14 in non-drug treated groups and day-7 in the Liv.52 treated groups. Similarly the values of monocytes and granulocytes percentage increased up to day-14 in the non-drug treated animals and day-7 in the drug treated animals thereafter; a

    Bone marrow transplantation from HLA identical family donors is the treatment of choice for children with severe aplastic anaemia (SAA). When there is no donor available, combined immunosuppressive therapy is given. evaluation of results of immunosupressive therapy in children with severe aplastic anaemia. SAA was diagnosed in 105 children (42 girls, 73 boys), aged 2-18 years, in the eleven haematological centres in Poland, between 1993-2007. All patients received the Severe Aplastic Anaemia Working Party of the EBMT protocol which included: antilymphocyte globulin or antithymocyte globulin, cyclosporin A, prednisolone. Granulocyto- or granulocytomacrophagic-cell stimulation factor was additionally administered during deep neutropenia. Haematological response was evaluated on day 84 or 112 and 180 of the therapy. complete remission occurred in 53 patients (51.5%), partial remission in 27 (24.7%), no response was obtained in 25 children (23.8%) on day 180, of the therapy. Period of observation was from 12 months to 12.5 years. During this time relapse occurred in 10 patients (9.5%). We observed 22 deaths: 8 early, during the first 3 months of IS and 14 after the first 3 months of immunosuppresive therapy (IS). At present 70 children (66.6%) are in first remission with lasts from 12 months to 12.5 years. The survival at 12.5-years is 78.6%. During the 12.5 years of follow-up we had two cases with a late clonal complication (PNH and MDS). Transformation to acute nonlymphoblastic leukaemia was observed in two of our patients. 1. Immunosuppresive therapy (IS) in children with SAA, without bone marrow family donors, is more effective after introduction of combined IS (12.5 years survival in this study was 80% for children with very severe aplastic anaemia (v SAA). 2. In our studies among the children followed up after IS therapy, there were: 1 case of periodic nocturnal haemoglobinuria (PNH), 1 case of myelodysplastic syndrome (MDS) and 2 cases of myeloid leukaemia

    BACKGROUND: Solid medical waste (SMW) in households is perceived to pose minimal risks to the public compared to SMW generated from healthcare facilities. While waste from healthcare facilities is subject to recommended safety measures to minimize risks to human health and the environment, similar...... waste in households is often untreated and co-mingled with household waste which ends up in landfills and open dumps in many African countries. In Ghana, the management of this potentially hazardous waste stream at household and community level has not been widely reported. The objective of this study...... likely to report harm in the household (OR 2.75, 95%CI 1.15-6.54). CONCLUSION: The belief that one can be harmed by diseases associated with SMW influenced reporting rates in the study area. Disposal practices suggest the presence of unwanted medicines and sharps in the household waste stream conferring...

    The recognition of the importance of Epstein-Barr virus (EBV) infection, including EBV-associated post-transplant lymphoproliferative disease (PTLD), has led to a new focus on the prevention of this problem. This paper reviews the scientific rationale behind, and clinical experience with, the use of chemoprophylaxis (using acyclovir or ganciclovir) and immunoprophylaxis (using intravenous immunoglobulin) in the prevention of EBV/PTLD. While some centers have already introduced the use of one or both of these agents as standard prophylaxis against the development of this complication, published data in support of these protocols are currently lacking. Well designed clinical trials are necessary to evaluate the potential role of both antiviral and immunoglobulin agents in the prevention of EBV/PTLD in organ transplant recipients.

    In the blood sera of pigs vaccinated with inactivated vaccines manufactured by three different manufacturers the RIA method was used to determine the specific antibodies to the virus of Aujeszky's disease. In certain groups of vaccinated pigs the results of the RIA examination are unfavourably affected by the bond of antibodies to the cellular antigenous determinants. This proves that following vaccination antibodies are formed not only against the viral antigen but also against the antigens of cells on which the vaccination virus is propagated. These shortcomings are eliminated by the use of suitable cellular cultures for the preparation of viral and control antigens. Antigens are applicable for RIA and for ELISA examinations of blood sera of infected and vaccinated pigs. The advantages are described of the RIA and ELISA methods as compared with the virus neutralization test.

    Full Text Available A total of 2001 unsexed day-old-chicks of each Fayoumi, Rhode Island Red (RIR, RIR × Fayoumi (RIFI and Fayoumi × RIR (FIRI were obtained from hatchery of Poultry Research Institute, Rawalpindi. The birds were maintained on deep litter system for a period of 20 weeks. The results revealed that the average day old weight was highest in RIR and FIRI, intermediate in RIFI and lowest in Fayoumi chickens. The RIR breed consumed more feed and gained maximum (P0.05 difference among pure and crossbred chickens. There was non-significant (P>0.05 difference in haematological values among all chickens. The total erythrocyte number, haemoglobin and packed cell volume increased with the advancement of age. However, erythrocyte sedimentation rate, mean corpuscular volume and mean corpuscular haemoglobin values decreased gradually with the advancement of age. It may be concluded that crossbred chickens gained better body weight than Fayoumi and moderate than RIR chickens with lower mortality. The crossbred chickens of FIRI showed better performance in all traits than crossbred chickens of RIFI.

    Treatment of cancer-related symptoms represents a major challenge for physicians. The purpose of this pilot study was to determine whether a brief bedside visual art intervention (BVAI) facilitated by art educators improves mood, reduces pain and anxiety in patients with haematological malignancies. Thirty-one patients (21 women and 10 men) were invited to participate in a BVAI where the goal of the session was to teach art technique for ~30 min. Primary outcome measures included the change in visual analog scale, the State-Trait Anxiety Inventory and the Positive and Negative Affect Schedule scale, from baseline prior to and immediately post-BVAI. Total of 21 patients (19 women and two men) participated. A significant improvement in positive mood and pain scores (p = .003 and p = .017 respectively) as well as a decrease in negative mood and anxiety (p = .016 and p = .001 respectively) was observed. Patients perceived BVAI as overall positive (95%) and wished to participate in future art-based interventions (85%). This accessible experience, provided by artists within the community, may be considered as an adjunct to conventional treatments in patients with cancer-related mood symptoms and pain, and future studies with balanced gender participation may support the generalisability of these findings. © 2018 John Wiley & Sons Ltd.

    Full Text Available Effects of higher levels of chromium alone and in combination with copper were investigated in broiler chicks divided into seven equal groups viz. A, B, C, D, E, F and G. Group G served as control receiving no treatment. Groups A, B and F received chromium chloride at the rate of 2 g/kg and nicotinic acid 150 mg/kg feed while C, D and F received chromium chloride 8 g/kg and nicotinic acid 150mg/kg. Broilers of groups A and C received copper sulfate at the rate of 200 mg/kg while groups Band D 400 mg/kg feed. Haematological parameters studied revealed non-significant difference between treatment groups and control in haemoglobin concentration and total erythrocyte counts. However, only at 4th week, lower PCV was observed in birds fed higher levels of chromium chloride alone. Increase in TLC was observed in birds fed low chromium alone or' with low levels of copper. Results of serum proteins including total protein, albumin and globulin during first three weeks showed significantly or relatively lower values in treatment groups than control. Serum globulins generally revealed non-significant difference between treatment groups and control.

    Under adverse obstetrical conditions, appropriate supervision and assistance during the immediate neonatal period are of the utmost importance, especially for weak calves. The aim of this study was to establish the effects of dystocia and oxytocin infusion on neonatal vitality, acid-base balance, and electrolyte and haematological homeostasis of dairy calves. Data were collected for 30 Holstein calves which were allocated to three groups: normal calving (n = 10); dystocia with mild to severe obstetric assistance (n = 10); and uterine inertia treated with oxytocin (n = 10). All 30 calves exhibited normothermia at birth, but had a significant decrease in body temperature after 60 min. Dystocic calves had lower Apgar scores than calves in the other two groups, and had respiratory and metabolic acidosis. Calves from normal calvings had normal blood pH, but base excess below the reference range. The mean partial pressure (Pa) of oxygen of calves whose dam had been treated with oxytocin was lower than that of calves from normal calvings. In all experimental groups, there was improvement in metabolic status in the first 60 min postpartum as PaCO2 values significantly decreased. All calves had normonatraemia, normokalaemia and normochloridaemia during the study period, but calves born to dams treated with oxytocin had a higher sodium concentration than those in the two other groups.

    Background Platelet transfusions are used in modern clinical practice to prevent and treat bleeding in people with thrombocytopenia. Although considerable advances have been made in platelet transfusion therapy since the mid-1970s, some areas continue to provoke debate especially concerning the use of prophylactic platelet transfusions for the prevention of thrombocytopenic bleeding. Objectives To determine whether agents that can be used as alternatives, or adjuncts, to platelet transfusions for people with haematological malignancies undergoing intensive chemotherapy or stem cell transplantation are safe and effective at preventing bleeding. Search methods We searched 11 bibliographic databases and four ongoing trials databases including the Cochrane Central Register of Controlled Trials (CENTRAL, 2016, Issue 4), MEDLINE (OvidSP, 1946 to 19 May 2016), Embase (OvidSP, 1974 to 19 May 2016), PubMed (e-publications only: searched 19 May 2016), ClinicalTrials.gov, World Health Organization (WHO) ICTRP and the ISRCTN Register (searched 19 May 2016). Selection criteria We included randomised controlled trials in people with haematological malignancies undergoing intensive chemotherapy or stem cell transplantation who were allocated to either an alternative to platelet transfusion (artificial platelet substitutes, platelet-poor plasma, fibrinogen concentrate, recombinant activated factor VII, desmopressin (DDAVP), or thrombopoietin (TPO) mimetics) or a comparator (placebo, standard care or platelet transfusion). We excluded studies of antifibrinolytic drugs, as they were the focus of another review. Data collection and analysis Two review authors screened all electronically derived citations and abstracts of papers identified by the review search strategy. Two review authors assessed risk of bias in the included studies and extracted data independently. Main results We identified 16 eligible trials. Four trials are ongoing and two have been completed but the results have

    The wide use of iron oxide nanoparticles (Fe{sub 2}O{sub 3} NPs) in various applications has raised great concerns worldwide. In this work, we measured the potential harmful effects of Fe{sub 2}O{sub 3} NP (<50 nm) at concentrations of 1 and 25 mg/L on haematological, biochemical, and ionoregulatory responses in an Indian major carp, Labeo rohita for a short-term period of 96 h. The results revealed significant (P < 0.05) decreases in haemoglobin, haematocrit, mean cellular volume, mean cellular haemoglobin, protein, sodium (Na{sup +}), potassium (K{sup +}), chloride (Cl{sup −}) and gill Na{sup +}/K{sup +}-ATPase levels in both the concentrations. White blood cell, mean cellular haemoglobin concentration and glucose levels were significantly (P < 0.05) increased in response to both concentrations during the study period. However, no significant changes in red blood cell count and gill Na{sup +}/K{sup +}-ATPase (25 mg/L) activity were noticed compared to those of the respective control groups. Based on this study, it was found that the Fe{sub 2}O{sub 3} NPs do have prominent effects on freshwater fish L. rohita. Our data suggest that the alterations of these parameters can be used as nonspecific biomarkers to monitor the environmental risks arising from nanoparticles in aquatic ecosystem and also regulate the use, production and release of nanoparticles.

    Objective: We assessed routinely-submitted LRFs to determine the degree of correctness, completeness and consistency. Methods: LRFs submitted to the Department of Haematology (DH and Blood Transfusion Services (BTS of Aminu Kano Teaching Hospital in Kano, Nigeria, between October 2014 and December 2014, were evaluated for completion of all items on the forms. Performance in four quality indicator domains, including patient identifiers, test request details, laboratory details and physician details, was derived as a composite percentage. Results: Of the 2084 LRFs evaluated, 999 were from DH and 1085 from BTS. Overall, LRF completeness was 89.5% for DH and 81.2% for BTS. Information on patient name, patient location and laboratory number were 100% complete for DH, whereas only patient name was 100% complete for BTS. Incomplete information was mostly encountered on BTS forms for physician’s signature (60.8% and signature of laboratory receiver (63.5%. None of the DH and only 9.4% of BTS LRFs met all quality indicator indices. Conclusion: The level of completion of LRFs from these two departments was suboptimal. This underscores the need to review and redesign the LRF, improve on training and communication between laboratory and clinical staff and review specimen rejection practices.

    The purpose of this study was to evaluate the use of combined transmission and emission tomography (TET) for correct localisation of heterotopic splenic tissue and differentiation of splenosis from other masses. The TET technique comprises the fusion of SPET and CT data obtained using the same imaging device to allow perfect overlap of anatomical and functional images. TET was performed in seven patients who either had haematological disorders and relapsing anaemia or thrombocytopenia after splenectomy or were under immunosuppression for different reasons. These patients presented 20 equivocal lesions on CT or MRI. Presence of splenic tissue was investigated using technetium-99m labelled colloids or heat-damaged red blood cells. Findings of spleen scintigraphy, TET and CT or MRI were compared with respect to localisation of splenosis and correct classification of lesions by CT or MRI. Histological validation was achieved by surgery or biopsy in all cases. All 20 lesions demonstrated by CT or MRI were correctly classified by TET as splenosis. Three additional lesions initially overlooked by CT or MRI could be detected. Diagnostic relevance was highest for intrahepatic, intrapulmonary or pleural splenic implants. It is concluded that TET allows exact localisation of heterotopic splenic tissue in patients with suspected splenosis. (orig.)

    Full Text Available Deoxynivalenol (DON, produced by the Fusarium genus, is a major contaminant of cereal grains used in the production of fish feed. The effect of mycotoxin deoxynivalenol on rainbow trout (Oncorhynchus mykiss was studied using a commercial feed with the addition of DON in a dose of 2 mg/kg feed. The fish (n=40 were exposed to the mycotoxin for 23 days. The trout were divided into two groups, control and experimental groups. Control groups were fed a commercial feed naturally contaminated with a low concentration of DON (225 μg/kg feed; experimental groups were fed a commercial feed with the addition of DON (1964 μg/kg feed. Plasma biochemical and haematological indices, biometric parameters, and histopathological changes were assessed at the end of the experiment. The experimental groups showed significantly lower values in MCH (P<0.05. In biochemical indices, after 23-day exposure, a significant decrease in glucose, cholesterol (P<0.05, and ammonia (P<0.01 was recorded in the experimental group compared to the control group. Our assessment showed no significant changes in biometric parameters. The histopathological examination revealed disorders in the caudal kidney of the exposed fish. The obtained data show the sensitivity of rainbow trout (O. mykiss to deoxynivalenol.

    Full Text Available Iron deficiency in early pregnancy and childhood can potentially have long-lasting effects on brain development and cognitive abilities and is ultimately engrossed with many confounding factors which need to be separated from the disease process in order to appreciate the real impact of this condition. Long-term studies are needed to assess whether normalisation of cognitive abilities with iron repletion therapy occurs, as they are currently sparse in the literature.

    There is limited clinical evidence on the utility of the monitoring of Epstein-Barr virus (EBV) DNAemia in the pre-emptive management of post-transplant lymphoproliferative disease (PTLD) in solid organ transplant (SOT) recipients. We investigated current preventive measures against EBV-related PTLD through a web-based questionnaire sent to 669 SOT programmes in 35 European countries. This study was performed on behalf of the ESGICH study group from the European Society of Clinical Microbiology and Infectious Diseases. A total of 71 SOT programmes from 15 European countries participated in the study. EBV serostatus of the recipient is routinely obtained in 69/71 centres (97%) and 64 (90%) have access to EBV DNAemia assays. EBV monitoring is routinely used in 85.9% of the programmes and 77.4% reported performing pre-emptive treatment for patients with significant EBV DNAemia levels. Pre-emptive treatment for EBV DNAemia included reduction of immunosuppression in 50.9%, switch to mammalian target of rapamycin inhibitors in 30.9%, and use of rituximab in 14.5% of programmes. Imaging by whole-body 18-fluoro-deoxyglucose positron emission tomography (FDG-PET) is used in 60.9% of centres to rule out PTLD and complemented computer tomography is used in 50%. In 10.9% of centres, FDG-PET is included in the first-line diagnostic workup in patients with high-risk EBV DNAemia. Despite the lack of definitive evidence, EBV load measurements are frequently used in Europe to guide diagnostic workup and pre-emptive reduction of immunosuppression. We need prospective and controlled studies to define the impact of EBV monitoring in reducing the risk of PTLD in SOT recipients.

    Invasive fungal infections (IFIs) are a primary cause of morbidity and mortality in patients with hematological malignancies. Establishing a definite diagnosis of IFI in immunocompromised patients is particularly challenging and time consuming, but delayed initiation of antifungal treatment increases mortality. The limited overall outcome has led to the strategy of initiating either 'empirical' or 'preemptive' antifungal therapy before the final diagnosis. However, diagnostic procedures have been vastly improved in recent years. Particularly noteworthy is the introduction of newer imaging techniques and non-culture methods, including antigen-based assays, metabolite detection and molecular detection of fungal DNA from body fluid samples. Though varying widely in cancer patients, the risk of IFI is highest in those with allogeneic stem cell transplantation and those with acute leukemia. The AGIHO presents recommendations for the diagnosis of IFIs with risk-adapted screening concepts for febrile episodes in patients with haemato-oncological disorders.

    CP-4126 (gemcitabine elaidate, previously CO-101) is a lipid-drug conjugate of gemcitabine designed to circumvent human equilibrative nucleoside transporter1-related resistance to gemcitabine. The purpose of this study was to determine the maximum tolerated dose (MTD) and the recommended phase II dose (RP2D) of CP-4126, and to describe its pharmacokinetic profile. Eligible patients with advanced refractory solid tumours, and adequate performance status, haematological, renal and hepatic function, were treated with one of escalating doses of CP-4126 administered by a 30-min intravenous infusion on days 1, 8 and 15 of a 28-day cycle. Blood and urine samples were collected to determine the pharmacokinetics (PKs) of CP-4126. Forty-three patients, median age 59 years (range 18-76; male = 27, female = 16), received one of ten dose levels (30-1600 mg/m(2)). Dose-limiting toxicities included grade 3 anaemia, grade 3 fatigue and grade 3 elevation of transaminases. The MTD and RP2D were 1250 mg/m(2) on basis of the toxicity and PK data. CP-4126 followed dose-dependent kinetics and maximum plasma concentrations occurred at the end of CP-4126 infusion. Seven patients achieved stable disease sustained for ≥3 months, including two patients with pancreatic cancer who had progressed on or after gemcitabine exposure. CP-4126 was well tolerated with comparable toxicity profile to gemcitabine. Future studies are required to determine its anti-tumour efficacy, either alone or in combination with other cytotoxic chemotherapy regimens.

  2. The Strategies to Homogenize PET/CT Metrics: The Case of Onco-Haematological Clinical Trials

    Full Text Available Positron emission tomography (PET has been a widely used tool in oncology for staging lymphomas for a long time. Recently, several large clinical trials demonstrated its utility in therapy management during treatment, paving the way to personalized medicine. In doing so, the traditional way of reporting PET based on the extent of disease has been complemented by a discrete scale that takes in account tumour metabolism. However, due to several technical, physical and biological limitations in the use of PET uptake as a biomarker, stringent rules have been used in clinical trials to reduce the errors in its evaluation. Within this manuscript we will describe shortly the evolution in PET reporting, examine the main errors in uptake measurement, and analyse which strategy the clinical trials applied to reduce them.

    Full Text Available Ketosis of lactating cows is among the most common metabolic diseases in modern dairy farms. The economic importance of the disease is caused by the reduced milk yield and body weight loss, poor feed conversion, lower conception rates, culling and increased mortality of affected animals. In the present study, a total of 47 high-yielding dairy cows up to 45 days in milk (DIM are included. All animals were submitted to physical examination wich included checking the rectal body temperature, heart rate, respiratory and rumen contraction rates, and inspection of visible mucous coats. The body condition was scored, and blood β-hydroxybutyrate (BHBA concentrations were assayed. The cows were divided into 3 groups: first group (control (n=24 with blood β-hydroxybutyrate level 2.6 mmol/l (clinical ketosis. Whole blood samples were obtained and analyzed for Red Blood Cell (RBC, 1012/l, Hemoglobin (HGB, g/l, Hematocrit (HCT, %, Mean Corpuscular Volume (MCV, fl, Mean Corpuscular Hemoglobin (MCH, pg, Mean Corpuscular Hemoglobin Concentration (MCHC, g/l, White Blood Cell (WBC, 109/l, Lymphocytes (LYM, 109/l, Monocytes (MON, 109/l, Granulocytes (GRA, 109/l, Red Blood Distribution Width (RDW, %, Red Blood Cell Distribution Width Absolute (RDWa, fl, Platelets (PLT, 109/l and Mean Platelet Volume (MPV, fl. In this study, deviations in the clinical parameters in the control group and in those with subclinical ketosis were not identified. The cows from the third group (clinical ketosis exhibited hypotonia, anorexia and body weight loss vs. control group. Hematological analysis showed leukocytosis and lymphocytosis in cows with subclinical ketosis vs. control group. In cows with clinical ketosis WBC counts decreased (leukopenia, while hemoglobin content and hematocrit values are higher vs. control group. Blood BHBA values are higher in both groups of ketotic cows vs. the control group. The other analyzed parameters (RBC, MCH, MCHC, MCV, RDW, RDWa, MON, GRA, PLT

    Solid phase coupled antibodies were introduced to facilitate the separation of bound and free labelled ligand in the competitive inhibition radioimmunoassay. Originally, the solid matrix used was in the form of small particles and since then a number of different matrices have been used such as very fine powder particles, gels, paper and plastic discs, magnetic particles and the inside surface of plastic tubes. The coupling of antibodies may be that of a covalent chemical binding, a strong physical adsorbtion, or an immunological binding to a solid phase coupled antigen. New principles of radioimmunoassay such as the solid phase sandwich techniques and the immunoradiometric assay were developped from the use of solid phase coupled antigens and antibodies. The solid phase sandwich techniques are reagent excess methods with a very wide applicability. Several of the different variants of solid phase techniques are suitable for automation. Advantages and disadvantages of solid phase radioimmunoassays when compared with those using soluble reagents are discussed. (orig.) [de

    We present an overview of solid-state optical refrigeration also known as laser cooling in solids by fluorescence upconversion. The idea of cooling a solid-state optical material by simply shining a laser beam onto it may sound counter intuitive but is rapidly becoming a promising technology for future cryocooler. We chart the evolution of this science in rare-earth doped solids and semiconductors.

    To implement evidence in a nursing unit and to gain a better understanding of the experience of change within a participatory action research. Study design of a participatory action research type was use from the constructivist paradigm. The analytical-methodological decisions were inspired by Checkland Flexible Systems for evidence implementation in the nursing unit. The study was carried out between March and November 2007 in the isolation unit section for onco-haematological patients in a tertiary level general university hospital in Spain. Accidental sampling was carried out with the participation of six nurses. Data were collected using five group meetings and individual reflections in participants' dairies. The participant observation technique was also carried out by researchers. Data analysis was carried out by content analysis. The rigorous criteria were used: credibility, confirmability, dependence, transferability and reflexivity. A lack of use of evidence in clinical practice is the main problem. The factors involved were identified (training, values, beliefs, resources and professional autonomy). Their daily practice (complexity in taking decisions, variability, lack of professional autonomy and safety) was compared with an ideal situation (using evidence it will be possible to normalise practice and to work more effectively in teams by increasing safety and professional recognition). It was decided to create five working areas about several clinical topics (mucositis, pain, anxiety, satisfaction, nutritional assessment, nauseas and vomiting, pressure ulcers and catheter-related problems) and seven changes in clinical practice were agreed upon together with 11 implementation strategies. Some reflections were made about the features of the study: the changes produced; the strategies used and how to improve them; the nursing 'subculture'; attitudes towards innovation; and the commitment as participants in the study and as healthcare professionals.

    The increasing trend of ban on the use of antibiotic growth promoters (AGPs) across the globe in the poultry industry has led to a growing need for alternatives to AGPs. Prebiotic, probiotic and their combination as a synbiotic have been considered as potential alternatives. This study aimed to investigate the effects of a prebiotic (isomaltooligosaccharide, IMO), a probiotic (PrimaLac®), and their combination (synbiotic) on hen performance, biochemical and haematological responses, and relative organ weights from 20 to 52 weeks of age. Supplementation of 1% IMO (PRE), 0.1% PrimaLac® (PRO) and 1% IMO + 0.1% PrimaLac® (SYN) improved (P feed intake and egg production at 20-36 weeks of age; body weight gain, feed conversion ratio and egg mass at 20-36 and 20-52 weeks of age; and egg weight at 20-36, 37-52 and 20-52 weeks of age. Compared to control-fed hens at 20-36 weeks of age, PRO- and SYN-fed hens produced less (P hens produced more large size eggs. From 37 to 52 weeks of age, PRE-, PRO- or SYN-fed hens produced less (P hens from 20 to 52 weeks of age. These results demonstrated the use of PRE, PRO and SYN as alternative feed additives to AGPs for improving the health and productivity of hens, while PRO is the best for commercial layer production to yield maximum profit.

    The vast potential of radiant energy opens vistas of new horizons as its use in various fields of science, technology, therapeutics and diagnosis. However its also exposes the global population to the hazards of nuclear accidents and radiation injury. In this era of nuclear science it has become a prerequisite to know the effects of radiation on mankind and to develop effective countermeasures for minimizing the damages of radiation exposure. Heavy metals like lead can cause deleterious effects when its concentration goes beyond the limit in ecosystem. The combined effects of radiation and lead further increases the causation of damages to organs and tissues. Amla is found to be a non toxic, inexpensive, easily available herbal drug. Therefore present study was pertain to evaluate the chemo preventive role of Amla against radiation and lead induced changes in blood of Swiss albino mice. The animals were exposed to 6.0 Gy of gamma rays and with or without lead acetate which was given to them adlibitum. The Emblica was administered seven days prior to irradiation or lead acetate treatment. Three animals were sacrificed from all the experimental group at each post treatment intervals of 1, 2, 4, 7, 14 and 28 days by cervical dislocation . The blood was collected in heparinised tube for estimating various haematological parameters. The value of RBC, WBC, PCV, Hemoglobin, and MCV decreased up to day-14 in non drug treated groups and day-7 in drug treated groups, thereafter the value increased. When the animals treated with radiation and lead simultaneously synergistic effects were observed. The Amla treated groups showed early and fast recovery thus, it may deduce from above observation that Amla has potential to check the alteration produced by radiation and lead in the blood of Swiss albino mice.

    Full Text Available The physiological challenges posed by hypobaric hypoxia warrant exploration of pharmacological entities to improve acclimatization to hypoxia. The present study investigates the preclinical efficacy of sphingosine-1-phosphate (S1P to improve acclimatization to simulated hypobaric hypoxia.Efficacy of intravenously administered S1P in improving haematological and metabolic acclimatization was evaluated in rats exposed to simulated acute hypobaric hypoxia (7620 m for 6 hours following S1P pre-treatment for three days.Altitude exposure of the control rats caused systemic hypoxia, hypocapnia (plausible sign of hyperventilation and respiratory alkalosis due to suboptimal renal compensation indicated by an overt alkaline pH of the mixed venous blood. This was associated with pronounced energy deficit in the hepatic tissue along with systemic oxidative stress and inflammation. S1P pre-treatment improved blood oxygen-carrying-capacity by increasing haemoglobin, haematocrit, and RBC count, probably as an outcome of hypoxia inducible factor-1α mediated erythropoiesis and renal S1P receptor 1 mediated haemoconcentation. The improved partial pressure of oxygen in the blood could further restore aerobic respiration and increase ATP content in the hepatic tissue of S1P treated animals. S1P could also protect the animals from hypoxia mediated oxidative stress and inflammation.The study findings highlight S1P's merits as a preconditioning agent for improving acclimatization to acute hypobaric hypoxia exposure. The results may have long term clinical application for improving physiological acclimatization of subjects venturing into high altitude for occupational or recreational purposes.

    Full Text Available Furadan, a carbamate pesticide is widely used in paddy fields and it has been detected in ground, surface and rain waters. In this study, fingerlings of Cyprinus carpio were exposed to different concentrations of furadan ranging from 25 to 50 mg L−1 for 96 h and the acute toxicity was calculated as 43.651 mg L−1. To assess the effect of furadan, fish were exposed to two concentrations of furadan (8.730 mg L−1, Treatment I and 4.365 mg L−1, Treatment II and certain haematological, biochemical and enzymological parameters were evaluated at the end of 24, 48, 72 and 96 h exposure periods with a recovery period of 96 h. A significant (p < 0.05 decrease in haemoglobin (Hb, haematocrit (Hct, red blood cells (RBC, plasma protein and glutamate oxaloacetate transaminase (GOT activity in gill, liver and kidney (except at the end of 96 h in Treatment I were noted in both the concentrations tested while white blood cells (WBC and glucose level were significantly increased after 24, 48, 72 and 96 h exposure periods when compared to untreated groups. A mixed trend in mean corpuscular volume (MCV, mean corpuscular haemoglobin (MCH and mean corpuscular haemoglobin concentration (MCHC and glutamate pyruvate transaminase (GPT activity in gill, liver and kidney was noted. During the recovery study period (96 h MCHC and plasma glucose level was recovered to some extent whereas the other parameters remain altered. The alterations of these parameters can be used to assess the toxic levels of the pesticide furadan on aquatic biota.

    Full Text Available Interstitial lung disease (ILD has been reported with the use of mammalian target of rapamycin inhibitors (mTORi. The clinical and safety databases of three Phase III trials of everolimus in de novo kidney (A2309, heart (A2310, and liver (H2304 transplant recipients (TxR were searched using a standardized MedDRA query (SMQ search for ILD followed by a case-by-case medical evaluation. A literature search was conducted in MEDLINE and EMBASE. Out of the 1,473 de novo TxR receiving everolimus in Phase III trials, everolimus-related ILD was confirmed in six cases (one kidney, four heart, and one liver TxR representing an incidence of 0.4%. Everolimus was discontinued in three of the four heart TxR, resulting in ILD improvement or resolution. Outcome was fatal in the kidney TxR (in whom everolimus therapy was continued and in the liver TxR despite everolimus discontinuation. The literature review identified 57 publications on ILD in solid organ TxR receiving everolimus or sirolimus. ILD presented months or years after mTORi initiation and symptoms were nonspecific and insidious. The event was more frequent in patients with a late switch to mTORi. In most cases, ILD was reversed after prompt mTORi discontinuation. ILD induced by mTORi is an uncommon and potentially fatal event warranting early recognition and drug discontinuation.

    Gaucher Disease is an autosomal recessive disease caused by the accumulation of glucocerebrosidase due to deficiency in lysosomal glucocerebrosidase. Thalassaemia trait is asymptomatic and is usually an incidental diagnosis. Both thalassaemia and Gaucher disease can have similar haematologic manifestations and hence, their coexistence causes diagnostic dilemma. Our patient presented at one-and-a-half years with weakness, pallor, failure to thrive and massive hepatosplenomegaly. Clinical examination and history pointed to a lipid storage disease. Peripheral smear revealed microcytic hypochromic cells and nucleated red cells with haemolytic blood picture. Thalassaemia trait was indicated on haemoglobin variant analysis using High Performance Liquid Chromatography. Liver biopsy, bone marrow aspirate and therapeutic splenectomy revealed Gaucher-like cells. Type 1 Gaucher disease can be clinically asymptomatic as well as present with massive liver and spleen enlargement and involvement of bone marrow. Anaemia, splenomegaly and thrombocytopenia are the usual presentations at diagnosis, similar to the haemoglobinopathies. Gaucher-like cells with normal beta-glucocerebrosidase (pseudo-Gaucher cells) are seen in thalassaemia, leukaemia, mycobacterial infections and myeloma. Gaucher disease coexisting with thalassaemia trait is uncommon. We report the occurrence of thalassaemia trait and Gaucher disease in a child, which resulted in confusion regarding the haematological diagnosis. This report highlights the necessity of independent establishment of the diagnosis in every patient so that appropriate management decisions are taken.

    Petroselinum crispum, a bright green biennial shrub is widely used traditionally as a food additive and herbal remedies for many ailments. This study therefore aimed to assess the toxic effects of its leaf extract using some biochemical, haematological parameters. The toxic effects were assessed by quantifying liver enzymes such as serum aspartate amino transferase (AST), alanine amino transferase (ALT), alkaline phosphatase (ALP), total serum protein and liver weight. Effects on haematological parameters were assessed by analysis of parked cell volume (PCV), red blood cell count (RBC), white blood cells (WBC) and haemoglobin (Hb) concentrations. Histopathological studies were done on the liver and kidneys. The extract caused significant increase in serum activity of alanine amino transferase and blood urea nitrogen (BUN) levels at the dose of 1000 mg/kg. Other biochemical and haematological parameters were not affected at lower doses. Conversely, the liver weight was not affected after eight weeks of treatment at the dose levels studied. The organs obtained for pathological study, were structurally unchanged under histopathological evaluation at lower doses but inflammatory and necrotic features were observed at doses ≥ 1000 mg/kg. The results indicate that the leaf ethanol extract of Petroselinum crispum was hepatotoxic and nephrotoxic at continued oral doses equal to or more than 1000 mg/kg, but no obvious toxicity when used at lower doses. Therefore, there should be caution in its administration to avoid overdosing and known interaction with some medications. In addition, the plant should be kept away from pets and domestic animals and should not be cultivated on soil irrigated with waste water due to their ability to bio-accumulate toxic metals.

It possesses antimalarial prophylactic property and has beneficial effect on blood components. Aim: To determine whether regular dietary supplement of UNCP mitigates high dose (HD artemether-lumefantrine (A-L-induced haematological disorders and the effect on nitric oxide (NO levels. Methods: Adult male guinea-pigs (300 g - 350 g were randomly divided into 5 groups of 6 guinea-pigs each. 3 groups were treated with UNCP (300, 900 and 1500 mg/kg body weight for 14 days. A-L (75 mg/kg was administered from the 12th to 14th day. One of the remaining 2 groups received distilled water only ie vehicle control group (VCG whilst the other received 75 mg/kg A-L only ie negative control group (NCG. Blood samples from all groups were obtained by cardiac puncture (day 15 followed by haematological and NO analysis. Results: A-L reduced white blood cells (WBC by 31.87%, lymphocyte count (45.99 %, haemoglobin (11.72%, haematocrit (18.56% and platelet count (33.08% in the NCG. Administration of various doses of UNCP increased WBC and lymphocyte count (P˃0.05 compared to the NCG. UNCP and A-L combination caused an increase in NO levels when compared to the VCG. Conclusion: Regular consumption of UNCP by guinea-pigs increases plasma NO and restores some haematological disorders induced by a 3-day HD A-L administration.

    Liquid slurries expected under normal in-tank processing (ITP) operations are not ignitible because of their high water content. However, deposits of dry solids from the slurries are combustible and produce dense, black smoke when burned. The dry solids burn similarly to Styrofoam and more easily than sawdust. It is the opinion of fire hazard experts that a benzene vapor deflagration could ignite the dry solids. A tetraphenylborate solids fire will rapidly plug the waste tank HEPA ventilation filters due to the nature of the smoke produced. To prevent ignition and combustion of these solids, the waste tanks have been equipped with a nitrogen inerting system

    2017-01-01

    Solid rockets are of interest to the space program because they are commonly used as boosters that provide the additional thrust needed for the space launch vehicle to escape the gravitational pull of the Earth. Larger, more advanced solid rockets allow for space launch vehicles with larger payload capacities, enabling mankind to reach new depths of space. This presentation will discuss, in detail, the history of solid rockets. The history begins with the invention and origin of the solid rocket, and then goes into the early uses and design of the solid rocket. The evolution of solid rockets is depicted by a description of how solid rockets changed and improved and how they were used throughout the 16th, 17th, 18th, and 19th centuries. Modern uses of the solid rocket include the Solid Rocket Boosters (SRBs) on the Space Shuttle and the solid rockets used on current space launch vehicles. The functions and design of the SRB and the advancements in solid rocket technology since the use of the SRB are discussed as well. Common failure modes and design difficulties are discussed as well.

    The importance of solid base catalysts has come to be recognized for their environmentally benign qualities, and much significant progress has been made over the past two decades in catalytic materials and solid base-catalyzed reactions. The book is focused on the solid base. Because of the advantages over liquid bases, the use of solid base catalysts in organic synthesis is expanding. Solid bases are easier to dispose than liquid bases, separation and recovery of products, catalysts and solvents are less difficult, and they are non-corrosive. Furthermore, base-catalyzed reactions can be performed without using solvents and even in the gas phase, opening up more possibilities for discovering novel reaction systems. Using numerous examples, the present volume describes the remarkable role solid base catalysis can play, given the ever increasing worldwide importance of "green" chemistry. The reader will obtain an overall view of solid base catalysis and gain insight into the versatility of the reactions to whic...

    To examine the advantage of liver and brain MRI in clinically anomalous haematological patients with fever of unknown origin. Material and Methods: Twenty liver MRI (T{sub 2}-TSE, T{sub 2}-HASTE, T{sub 1}-FLASH{+-}Gd dynamic) and 16 brain MRI (T{sub 2}-TSE, FLAIR, T{sub 1}-TSE{+-}Gd) were performed searching for a focus of fever with a suspected organ system. Comparison with clinical follow-up. Results: suspected organ system. Comparison with clinical follow-up. Results: A focus was detected in 11/20 liver MRI. Candidiasis (n=3), mycobacteriosis (n=2), relapse of haematological disease (n=3), graft versus host disease (n=1), non-clarified (n=2). The remaining 9 cases with normal MRI were not suspicious of infectious hepatic disease during follo-wup. In brain MRI, 3/16 showed a focus (toxoplasmosis, aspergillosis, mastoiditis). Clinical indication for an infectious involvement of the brain was found in 4/16 cases 2--5 months after initially normal brain MRI. No suspicion of an infectious involvement of brain was present in the remaining 9/16 cases. Conclusion: In case of fever of unknown origin and suspicion of liver involvement, MRI of the liver should be performed due to data given in literature and its sensitivity of 100%. Because of the delayed detectability of cerebral manifestations, in cases of persisting suspicion even a previously normal MRI of the brain should be repeated. (orig.)

    Full Text Available Protein-calorie malnutrition (PCM is usually found in children, the elderly, patients suffering from neoplasia or chronic disease, patients undergoing chemotherapy, or even patients under parenteral nutrition. PCM presents a wide spectrum of signs and symptoms that are a result of not only the cause(s that led to malnutrition, but also of the different degrees of protein or carbohydrate deficiency. Here we present data obtained from observational and experimental epidemiological studies that suggest that malnourished individuals frequently present a greater susceptibility to infection with high morbidity and mortality indices. Data both found in literature and obtained by our group evidence that malnutrition modifies the organism's defence processes, impairing lympho-haematopoietic organs and modifying immune response. The haematological alterations in malnutrition, such as leucopoenia and hypoplasia, are described, with an emphasis on the results in experimental protein malnutrition obtained by our group. In particular, the structural and ultra-structural alterations of bone marrow, spleen and thymus; functional alterations such as the reduction of cell migration and spreading, phagocytosis, bactericidal and fungicidal activity as well as alterations in the production of reactive oxygen species are discussed. The implications of modifications of the haemopoietic environment in malnutrition states are still obscure, however, they seem to be responsible for inefficient haemopoiesis, especially inefficient myelopoiesis, and they seem to be irreversible over the short-term.Desnutrição protéico-calórica (DPC é geralmente encontrada em crianças, idosos, pacientes com neoplasias ou doenças crônicas, pacientes submetidos à quimioterapia ou à nutrição parenteral.

    nab-Paclitaxel has demonstrated efficacy in adults with solid tumours and preclinical activity in paediatric solid tumour models. Results from phase I of a phase I/II study in paediatric patients with recurrent/refractory solid tumours treated with nab-paclitaxel are reported. Patients with recurrent/refractory extracranial solid tumours received nab-paclitaxel on days 1, 8 and 15 every 4 weeks at 120, 150, 180, 210, 240, or 270 mg/m 2 (rolling-6 dose-escalation) to establish the maximum tolerated dose (MTD) and recommended phase II dose (RP2D). Sixty-four patients were treated. Dose-limiting toxicities were grade 3 dizziness at 120 mg/m 2 and grade 4 neutropenia >7 days at 270 mg/m 2 . The most frequent grade 3/4 adverse events were haematologic, including neutropenia (36%), leukopenia (36%) and lymphopenia (25%). Although the MTD was not reached, 270 mg/m 2 was declared non-tolerable due to grade 3/4 toxicities during cycles 1-2 (neutropenia, n = 5/7; skin toxicity, n = 2/7; peripheral neuropathy, n = 1/7). Of 58 efficacy-evaluable patients, complete response occurred in one patient (2%; Ewing sarcoma) and partial responses in four patients (7%; rhabdomyosarcoma, Ewing sarcoma, renal tumour with pulmonary metastases [high-grade, malignant] and sarcoma not otherwise specified); all responses occurred at ≥210 mg/m 2 . Thirteen patients (22%) had stable disease (5 lasting ≥16 weeks) per RECIST. nab-Paclitaxel 240 mg/m 2 qw3/4 (nearly double the adult recommended monotherapy dose for this schedule in metastatic breast cancer) was selected as the RP2D based on the tolerability profile, pharmacokinetics and antitumour activity. Phase II is currently enrolling patients with recurrent/refractory neuroblastoma, rhabdomyosarcoma and Ewing sarcoma. CLINICALTRIALS.GOV: NCT01962103. 2013-000144-26. Copyright © 2018 Elsevier Ltd.

    Full Text Available Treatment of patients suffering from chronic hepatitis C with standard pegylated interferon alpha 2a plus ribavirin has limited efficacy. Therapy outcome is dependent on several factors of both the host and virus, including age, sex, stage of fibrosis, viral genotype, viral load, and occurrence of haematological adverse events during chronic hepatitis C treatment. The aim of this study was to determine the relationship between the viral and host factors and the haematological side effects of therapy with sustained virological response.

    To evaluate the adverse effects of flunixin, ketoprofen and phenylbutazone when administered I/V to clinically normal miniature donkeys. Twenty clinically normal adult (2.0-2.5 years old) male miniature donkeys weighing 113-136 kg and 0.81- 0.86 m tall were randomly assigned to one of four groups, and administered either saline (n=5), 1.0 mg/kg flunixin (n=5), 2.2 mg/kg ketoprofen (n=5), or 4.4 mg/kg phenylbutazone (n=5) I/V at 0800 hours on Day 1, then every 12 h, for 12 days. The animals were observed every 8 h, and examined physically daily. Blood, faeces and urine samples were collected daily from all donkeys, for haematological indices and enzyme activities, occult blood, and urinalysis, respectively. Immediately after euthanasia, complete post-mortem examinations were performed on all donkeys, and gross lesions recorded. Histopathology was conducted on a wide range of tissues. Clinically, mild anorexia and diarrhoea were observed during the study only in donkeys treated with phenylbutazone. There was an effect of treatment with the non-steroidal anti-infl ammatory drugs (NSAID) on red blood cell (RBC) counts, packed cell volume (PCV) and enzyme activities, but not on urine. Lesions were observed in the glandular mucosa of the stomach of all donkeys treated with NSAID, including ulceration in most. Also, in donkeys treated with NSAID, hyperaemia, erosion and ulceration of the gastrointestinal tract, and congestion of the liver, kidney and spleen, were observed. Microscopically, hepatic and renal lesions comprised biliary hyperplasia and interstitial nephritis, respectively. The gastrointestinal, hepatic and renal lesions observed in the donkeys treated with NSAID demonstrated the toxic potential of NSAID, which was greatest for animals treated with phenylbutazone, less for flunixin, and least for ketoprofen. When use of these compounds is contemplated in clinical cases, the risk of adverse effects and the comparative toxic potential should be considered

    Radioprotective effect of cysteine, vitamin E and their combination on γ-irradiation-induced alteration in some haematological parameters in male rats has been studied 24 and 48 hrs after whole-body γ-irradiation at a dose level of 7.5 Gy. The results of this study reveal that γ-irradiation caused a significant decrease in red blood cells (RBCs) count with insignificant change in hemoglobin level, 24 and 48 hrs postirradiation, γ-irradiated rats showed as well a progressive decrease in their blood ATP, and serum-SH levels with a significant increase in blood glutathione (GSH) level. Administration of cysteine or vitamin E preceeding γ-radiation exposure gave a significant radioprotection to the above haematological parameters. However, combination of both agents afforded a better protection, so that most of the measured parameters were restored to the pre-irradiated values. Finally, the data demonstrate that the radioprotection provided by combined adminsistration of vitamin E and cysteine is feasible and perhaps, even more efficient against radiation injury to RBCs. This will appreciate the usage of such combination in protecting the patient during radiotherapy. (orig.) [de

    Full Text Available The objective of our study was to assess the effect of replacing soybean meal with the meal from whole white lupin seeds (Lupinus albus of the Zulika variety in diets on selected haematological indicators in 40-day-old fattened hybrid mallard ducks. A total of 180 Cherry Valley ducks were divided into three groups (E1, E2, and control. The control group was fed a diet containing soybean meal. Soybean meal replaced with 50% and 100% meal of white lupin seeds were used in group E1 and group E2, respectively. At the end of the fattening, 12 ducks (6 males and 6 females were randomly selected from each group for a haematological examination. From the result of this study, it is clear that the effect of the diet was found only on the slightly varying number of white blood cells and on the proportion of monocytes. Ducks of group E2 showed a slight increase in the total number of leukocytes which was accompanied by a decrease in the percentage share of monocytes (P < 0.05. Based on the results, it can be claimed that the replacement of soybean meal with meal from the Zulika variety of whole white lupin seeds in the diet did not have a negative effect on the determined blood indicators. Therefore, whole white lupin seeds were successfully used as the important protein component of the diet for fattening hybrid mallard ducks.

    Full Text Available African locust bean (Parkia biglobosa seed is rich in protein and has recently found its way into the feed industry. This research was conducted to determine the growth performance, haematological profile and nutrient digestibility by broiler chickens fed diets containing soaked and fermented African locust bean (Parkia biglobosa seed meal (SFALBSM. Five diets were formulated in which SFALSBM was included at graded levels of 0, 7.5, 15, 22.5 and 30% designated as T1, T2, T3, T4 and T5 respectively. Two hundred and twenty five (225 day old broiler chickens (Marshall Strain were fed these diets in a completely randomized design and each treatment was replicated three times with 15 birds per replicate. The experiment lasted 8 weeks (4week starter phase and 4week finisher phase. The results of performance of broiler chicks at starter phase showed there were differences (P0.05 on digestibility of dry matter, crude protein and ash. The crude fibre, ether extract and nitrogen free extract digestibility were affected by treatments (P<0.05. Birds fed T3 had highest crude fibre digestibility value (P<0.05. It was concluded that soaked and fermented African locust bean seed meal can be included in broiler chickens diets up to 15% dietary level at the starter phase and 22.5% at the finisher phase without any adverse effect on performance, haematological profile and nutrient digestibility.

    Full Text Available In the present study, the median lethal concentration (LC 50 of neem leaf extract to Cirrhinus mrigala for 24 h was found to be 1.035 g l-l. During the study period, the haematological parameters including Hb, Hct, RBC, MCV, MCH and MCHC levels were significantly decreased in neem leaf extract exposed fish when compared to the control fish whereas WBC count was increased. Similarly, plasma Na+ and Cl- levels were significantly lower and K+ level were significantly higher when compared to the control. In biochemical study, elevated plasma glucose and induced protein levels were noticed. The enzymes, glutamate oxaloacetate transaminase (GOT and glutamate pyruvate transaminase (GPT activities were increased significantly in gill, liver and muscle of treated fish compared to that of their control groups. The results of the present investigation suggest that neem leaf extracts affects the hematological, ionoregulatory, biochemical and enzymological parameters of fish and alterations of these parameters can be useful in environmental biomonitoring of neem based products in freshwater environment.Keywords: Azadirachta indica, Acute toxicity, Cirrhinus mrigala, Haematology, Ion regulation, Biochemical and Enzymological parameters.

    To investigate possibilities of magnetic resonance imaging at high magnetic fields in humans, a whole-body magnet with a magnetic field density of 4 T was developed. Due to the few data that are available at present on biological effects and side effects of such high fields, a reproduction experiment with NMRI mice was performed using a crossover design. The mice were allowed to mate during a 7-day period within the field or after their stay in the field. The number of pregnant mice and foetuses were recorded and compared to the controls. Another group was held within the magnetic field during the whole period of pregnancy until day 18, one day before delivery. In all groups, development of the foetuses was studied. Additionally, haematological parameters of the males and females were estimated and necroscopy was performed. Brains, lungs and optical nerves were investigated using pathohistological techniques. It could be shown that in case of mating within the magnetic field, the number of pregnant mice was considerably reduced. This effect was, however, completely reversible if mating occurred after the stay in the field. Malformations retardations or an increased number of resorptions were never found. The haematological parameters were, in general, not changed. Necroscopy as well as pathohistological investigations showed no pathological alterations. Therefore, it appears that whereas high magnetic fields reduce the activity of mating behaviour, they do not exert any influence on physiological parameters. (orig.) [de

    Effects of serum iron (Fe), haematological variables and on blood lactate levels before and after treadmill exercise or transport to the slaughterhouse, on meat traits, and on growth performance of feeding milk replacer (MR), planned to contain 10, 20, 30, 40, 50 or 80 mg Fe/kg, were studied in veal calves. If supplied less than 50 mg Fe/kg MR, calves developed hypoferraemia and anaemia, the degree of which was dependent on Fe intake. Serum Fe concentration, saturation of transferrin with Fe and the degree of anaemia in calves fed 20 or 10 mg Fe/kg MR were nearly identical. Serum Fe concentration and haematological traits barely changed in calves fed 50 mg Fe/kg MR during the growth trail, but serum Fe concentration increased when MR contained 80 mg Fe/kg in calves fed 50 or more Fe/kg MR. Growth performance was smaller in calves fed 10 mg Fe/kg MR than in those fed greater amounts of Fe/kg MR. Carcass taxation was inversely related to Fe intake. In conclusion, MR containing only 10 mg Fe/kg caused marked anaemia and reduced growth performance. Feeding MR with only 20 mg Fe/kg is not necessarily sufficient to prevent development of severe anaemia. Feeding MR with 50 mg Fe/kg would seem to be physiologically the most appropriate amount of Fe for veal calves, but was too high for acceptable carcass taxation.

    Amodiaquine (AQ), an effective antimalarial drug for uncomplicated malaria, has been greatly restricted after cases of life-threatening agranulocytosis and hepatic toxicity during prophylactic use. We conducted a hospital based open-label randomised clinical trial in 40 indigenous semi-immune healthy adult male volunteers with and without malaria parasites. The objective was to collect data on biological and haematological safety, tolerability, and parasitological efficacy to serve as baseline in the evaluation of the effectiveness of AQ preventive intermittent treatment against malaria morbidity in infants. Volunteers were stratified according to parasitaemia status and randomly assigned 20 participants each arm to three days treatment with either AQ or chloroquine (CQ). The level of difference of selected haematological and hepatological values pre-and post-trial were marginal and within the normal limits. Clinical adverse effects mostly mild and transient were noticed in 33.3% CQ treated-aparasitaemic, 23.8% of CQ treated-parasitaemic, 28.6% ofAQ-treated parasitaemic and 14.3% of aparasitaemic receiving AQ. Amodiaquine attained 100% parasitological clearance rate versus 70% in CQ-treated volunteers. The findings indicate that there was no agranulocytosis or hepatic toxicity suggesting that AQ may pose no public health risk in its wide therapeutic dosage uses. Larger studies are needed to exclude rare adverse effects.

Methods: Rats were orally administered distilled water, diethylnitrosamine (30 mg/kg body weight once a week on weeks 3 and 4, curcumin (200 mg/kg body weight, extracts and 1:1 mixture (200, 400 and 800 mg/kg body weight for 4 weeks. Malondialdehyde, markers of oxidative stress and hematological indices were evaluated. Results: The extracts and their mixture significantly (P<0.05 reversed the diethylnitrosamine-induced alterations in the levels of liver malondialdehyde, superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase, glucose 6-phosphate dehydrogenase, glutathione, vitamin C and platelet counts. The other haematological parameters (red blood cell count, haemoglobin concentration, packed cell volume, mean corpuscular volume, mean corpuscular haemoglobin, mean corpuscular haemoglobin concentration, white blood cell count, lymphocyte count and neutrophil count were not affected by diethylnitrosamine and extracts. Conclusion: The extracts possess antioxidant, hepatoprotective and haemoprotective activities that compared well with curcumin. These activities were better exhibited by the mixture than the individual extracts.

    Waste management workers (WMWs) around the world are at risk of work-related health disorders. The influence of employment duration on individuals occupationally exposed to solid waste was investigated in this study. The study comprised (n = 280) 180 WMWs and 100 controls. Employment duration was obtained from questionnaire survey and categorized into three groups: group I (0.5-2 years), group II (>2-4 years) and group III (>4-6 years). Blood sample (10 ml) was collected from the antecubital vein of subjects for analysis. WMWs exhibited significantly (p < 0.001) elevated inflammatory markers (erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and ceruloplasmin (Cp)) relative to control. While Cp increased, ESR and CRP decreased with increasing WMWs' employment duration. Alteration in oxidant/antioxidant markers was characterized by significant (p < 0.001) decrease in ferric-reducing ability of plasma (FRAP) and catalase activity together with marked (p < 0.01) elevation of thiobarbituric acid reactive substances (TBARS) and uric acid (UA). TBARS, UA and FRAP increased while catalase decreased with WMWs' employment duration. In addition, WMWs exhibited significantly (p < 0.01) elevated immunoglobulin A (IgA) and IgG, which also increased and decreased, respectively, with job duration. The significantly (p < 0.01) decreased haemoglobin and haematocrit levels as well as the significantly (p < 0.001) elevated total leukocytes in WMWs increased with employment duration. Alanine aminotransferase increased and albumin decreased significantly (p < 0.05) in WMWs, and these changes also increased and decreased, respectively, with job duration. Data suggest that levels of alteration of important systemic markers of health/disease are related to WMWs' employment or exposure duration.

    The 8-quinolineboronic acid phosphorescent molecular switch (abbreviated as PMS-8-QBA. Thereinto, 8-QBA is 8-quinolineboronic acid, and PMS is phosphorescent molecular switch) was found for the first time. PMS-8-QBA, which was in the "off" state, could only emit weak room temperature phosphorescence (RTP) on the acetyl cellulose membrane (ACM). However, PMS-8-QBA turned "on" automatically for its changed structure, causing that the RTP of 8-QBA in the system increased, after PMS-8-QBA-WGA (WGA is wheat germ agglutinin) was formed by reaction between -OH of PMS-8-QBA and -COOH of WGA. More interesting is that the -NH 2 of PMS-8-QBA-WGA could react with the -COOH of alkaline phosphatase (AP) to form the affinity adsorption (AA) product WGA-AP-WGA-8-QBA-PMS (containing -NH-CO- bond), which caused RTP of the system to greatly increase. Thus, affinity adsorption solid substrate room temperature phosphorimetry using PMS-8-QBA as labelling reagent (PMS-8-QBA-AA-SSRTP) for the determination of trace AP was established. The method had many advantages, such as high sensitivity (the detection limit (LD) was 2.5 zg spot -1. For sample volume of 0.40 μl spot -1, corresponding concentration was 6.2 × 10 -18 g ml -1), good selectivity (the allowed concentration of coexisting material was higher, when the relative error was ±5%), high accuracy (applied to detection of AP content in serum samples, the result was coincided with those obtained by enzyme-linked immunoassay), which was suitable for the detection of trace AP content in serum samples and the forecast of human diseases. Meanwhile, the mechanism of PMS-8-QBA-AASSRTP was discussed. The new field of analytical application and clinic diagnosis technique of molecule switch are exploited, based on the phosphorescence characteristic of PMS-8-QBA, the AA reaction between WGA and AP, as well as the relation between AP content and human diseases. The research results promote the development and interpenetrate among molecule

    Nursing shortage is a global issue that which affects oncology nursing. Oncology nurses are more prone to experience job dissatisfaction, stress and burnout when they work in units with poor staffing. There is thus a need for greater understanding of the relationship between the nursing shortage and nursing outcomes in oncology/haematology settings. This review aimed to establish the best available evidence concerning the relationship between the nursing shortage and nurses' job satisfaction, stress and burnout levels in oncology/haematology settings; and to make recommendations for practice and future research. Types of participants: This review considered studies that included oncology registered nurses (RNs) who were more than 18 years of age and worked in either inpatient or outpatient oncology/haematology wards or units for the adult or paediatric patients.Types of intervention: This review considered studies that evaluated the relationship between the nursing shortage and nurses' job satisfaction, stress and burnout levels in oncology/haematology settings.Types of outcomes: This review included studies that measured job satisfaction, stress and burnout levels using different outcomes measures. Job satisfaction was determined by the Measure of Job Satisfaction scale, the Misener Nurse Practitioner Job Satisfaction Scale and the Likert scale, stress by the Pediatric Oncology Nurse Stressor Questionnaire and burnout by the Maslash Burnout Inventory scale.Types of studies: This review included descriptive/descriptive-correlational studies which were published in English. The search strategy sought to identify published and unpublished studies conducted between 1990 and 2010. Using a three-step search strategy, the following databases were accessed: CINAHL, Medline, Scopus, ScienceDirect, PsycInfo, PsycArticles, Web of Science, The Cochrane Library, Proquest and Mednar. Two independent reviewers assessed each paper for methodological validity prior to inclusion in

    Density Functional Theory (DFT) is a successful and well-established theory for the study of the structure of simple and complex fluids at equilibrium. The theory has been generalized to dynamical situations when the underlying dynamics is diffusive as in, for example, colloidal systems. However, there is no such a clear foundation for Dynamic DFT (DDFT) for the case of simple fluids in contact with solid walls. In this work, we derive DDFT for simple fluids by including not only the mass density field but also the momentum density field of the fluid. The standard projection operator method based on the Kawasaki-Gunton operator is used for deriving the equations for the average value of these fields. The solid is described as featureless under the assumption that all the internal degrees of freedom of the solid relax much faster than those of the fluid (solid elasticity is irrelevant). The fluid moves according to a set of non-local hydrodynamic equations that include explicitly the forces due to the solid. These forces are of two types, reversible forces emerging from the free energy density functional, and accounting for impenetrability of the solid, and irreversible forces that involve the velocity of both the fluid and the solid. These forces are localized in the vicinity of the solid surface. The resulting hydrodynamic equations should allow one to study dynamical regimes of simple fluids in contact with solid objects in isothermal situations.
