The commonest forms are the various types of LEUKEMIA, of LYMPHOMA, and of the progressive, life-threatening forms of the MYELODYSPLASTIC SYNDROMES.Hemoglobinometry: Measurement of hemoglobin concentration in blood.Hospital Units: Those areas of the hospital organization not considered departments which provide specialized patient care. They include various hospital special care wards.Clinical Chemistry Tests: Laboratory tests demonstrating the presence of physiologically significant substances in the blood, urine, tissue, and body fluids with application to the diagnosis or therapy of disease.Febrile Neutropenia: Fever accompanied by a significant reduction in the number of NEUTROPHILS.Autoanalysis: Method of analyzing chemicals using automation.Leukocyte Count: The number of WHITE BLOOD CELLS per unit volume in venous BLOOD. A differential leukocyte count measures the relative numbers of the different types of white cells.Medical Oncology: A subspecialty of internal medicine concerned with the study of neoplasms.Automation: Controlled operation of an apparatus, process, or system by mechanical or electronic devices that take the place of human organs of observation, effort, and decision. (From Webster's Collegiate Dictionary, 1993)Laboratories, Hospital: Hospital facilities equipped to carry out investigative procedures.No-Observed-Adverse-Effect Level: The highest dosage administered that does not produce toxic effects.Platelet Count: The number of PLATELETS per unit volume in a sample of venous BLOOD.Punched-Card SystemsOncology Service, Hospital: The hospital department responsible for the administration and provision of diagnostic and therapeutic services for the cancer patient.Hematocrit: The volume of packed RED BLOOD CELLS in a blood specimen. The volume is measured by centrifugation in a tube with graduated markings, or with automated blood cell counters. It is an indicator of erythrocyte status in disease. For example, ANEMIA shows a low value; POLYCYTHEMIA, a high value.Chemistry, Clinical: The specialty of ANALYTIC CHEMISTRY applied to assays of physiologically important substances found in blood, urine, tissues, and other biological fluids for the purpose of aiding the physician in making a diagnosis or following therapy.Hemoglobins: The oxygen-carrying proteins of ERYTHROCYTES. They are found in all vertebrates and some invertebrates. The number of globin subunits in the hemoglobin quaternary structure differs between species. Structures range from monomeric to a variety of multimeric arrangements.MycosesEquipment and Supplies, Hospital: Any materials used in providing care specifically in the hospital.Erythrocyte Indices: ERYTHROCYTE size and HEMOGLOBIN content or concentration, usually derived from ERYTHROCYTE COUNT; BLOOD hemoglobin concentration; and HEMATOCRIT. The indices include the mean corpuscular volume (MCV), the mean corpuscular hemoglobin (MCH), and the mean corpuscular hemoglobin concentration (MCHC).Laboratories: Facilities equipped to carry out investigative procedures.Automation, Laboratory: Controlled operations of analytic or diagnostic processes, or systems by mechanical or electronic devices.Pathology Department, Hospital: Hospital department which administers and provides pathology services.Cancer Care Facilities: Institutions specializing in the care of cancer patients.ItalyPathology: A specialty concerned with the nature and cause of disease as expressed by changes in cellular or tissue structure and function caused by the disease process.Anemia: A reduction in the number of circulating ERYTHROCYTES or in the quantity of HEMOGLOBIN.Mannans: Polysaccharides consisting of mannose units.Hospital Departments: Major administrative divisions of the hospital.Blood Specimen Collection: The taking of a blood sample to determine its character as a whole, to identify levels of its component cells, chemicals, gases, or other constituents, to perform pathological examination, etc.Infectious Disease Medicine: A branch of internal medicine concerned with the diagnosis and treatment of INFECTIOUS DISEASES.Clinical Laboratory Techniques: Techniques used to carry out clinical investigative procedures in the diagnosis and therapy of disease.Job Application: Process of applying for employment. It includes written application for employment or personal appearance.Workflow: Description of pattern of recurrent functions or procedures frequently found in organizational processes, such as notification, decision, and action.Cross Infection: Any infection which a patient contracts in a health-care institution.Aspergillosis: Infections with fungi of the genus ASPERGILLUS.Toxicity Tests, Chronic: Experiments designed to determine the potential toxic effects of a long-term exposure to a chemical or chemicals.Chemotherapy-Induced Febrile Neutropenia: FEVER accompanied by a significant reduction in NEUTROPHIL count associated with CHEMOTHERAPY.Toxicity Tests: An array of tests used to determine the toxicity of a substance to living systems. These include tests on clinical drugs, foods, and environmental pollutants.Reticulocyte Count: The number of RETICULOCYTES per unit volume of BLOOD. The values are expressed as a percentage of the ERYTHROCYTE COUNT or in the form of an index ("corrected reticulocyte index"), which attempts to account for the number of circulating erythrocytes.Neoplasms: New abnormal growth of tissue. Malignant neoplasms show a greater degree of anaplasia and have the properties of invasion and metastasis, compared to benign neoplasms.Training Support: Financial support for training including both student stipends and loans and training grants to institutions.Body Weight: The mass or quantity of heaviness of an individual. It is expressed by units of pounds or kilograms.Invasive Pulmonary Aspergillosis: Lung infections with the invasive forms of ASPERGILLUS, usually after surgery, transplantation, prolonged NEUTROPENIA or treatment with high-doses of CORTICOSTEROIDS. Invasive pulmonary aspergillosis can progress to CHRONIC NECROTIZING PULMONARY ASPERGILLOSIS or hematogenous spread to other organs.Blood Cells: The cells found in the body fluid circulating throughout the CARDIOVASCULAR SYSTEM.Equipment Safety: Freedom of equipment from actual or potential hazards.Antifungal Agents: Substances that destroy fungi by suppressing their ability to grow or reproduce. They differ from FUNGICIDES, INDUSTRIAL because they defend against fungi present in human or animal tissues.Bacteremia: The presence of viable bacteria circulating in the blood. Fever, chills, tachycardia, and tachypnea are common acute manifestations of bacteremia. The majority of cases are seen in already hospitalized patients, most of whom have underlying diseases or procedures which render their bloodstreams susceptible to invasion.
