Abstract
A normal pregnancy consumes 500-800 mg of iron from the mother. Premenopausal women have a high incidence of marginal iron stores or iron deficiency (ID), with or without anemia, particularly in the less developed world. Although pregnancy is associated with a "physiologic" anemia largely related to maternal volume expansion; it is paradoxically associated with an increase in erythrocyte production and erythrocyte mass/kg. ID is a limiting factor for this erythrocyte mass expansion and can contribute to adverse pregnancy outcomes. This review summarizes erythrocyte and iron balance observed in pregnancy; its implications and impact on mother and child; and provides an overview of approaches to the recognition of ID in pregnancy and its management, including clinically relevant questions for further investigation.

Abstract
Background Patients with anemia are frequently encountered in primary care. Once anemia is detected, it is essential to define the type and identify the underlying cause prior to initiation of treatment. In most cases, the cause can be determined using information from the patient history, physical exam, and complete blood counts (CBC). Point of care testing of blood cell counts would speed up the work up of anemia patients. The aim of the present study was to evaluate if the HemoScreen™ instrument (PixCell Medical, Yokneam Ilit, Israel) could be used for primary care samples. It is a POCT instrument that utilizes single sample cuvettes and image analysis of full blood count including RBC, Hemoglobin, MCV, MCH, platelets, WBC, and WBC 5-part differential. Methods We compared the HemoScreen™ and the Sysmex XN instrument results of 100 primary care patient samples focusing on the total white blood cells, red blood cell parameters RBC, Hemoglobin, MCH, MCV and platelets. Results Deming correlations between the HemoScreen™ and the Sysmex XN instruments for the CBC were WBCHemoScreen™ = 1.016* WBCSysmex + 0.34; r = 0.981, RBCHemoScreen™ = 0.988* RBCSysmex + 0.015; r = 0.974, HemoglobinHemoScreen™ = 1.081* HemoglobinSysmex − 11.25; r = 0.964, MCHHemoScreen™ = 0.978* MCHSysmex + 0.78; r = 0.939, MCVHemoScreen™ = 0.963* MCVSysmex + 8.68; r = 0.946, PlateletsHemoScreen™ = 0.964* PlateletsSysmex + 25.7; r = 0.953. Conclusion The HemoScreen™ instrument could provide rapid and accurate test results for evaluation of the red blood cell parameters in primary care. This new technology is interesting as it allows the analysis red blood cell parameters also at small primary care centers.

Abstract
Anemia is a common condition and is diagnosed on laboratory assessment. It is defined by abnormally low hemoglobin concentration or decreased red blood cells. Several classification systems exist. Laboratory markers provide important information. Acute anemia presents with symptoms owing to acute blood loss; chronic anemia may present with worsening fatigue, dyspnea, lightheadedness, or chest pain. Specific treatments depend on the underlying anemia and etiology. Iron is an alternative treatment for patients with microcytic anemia owing to iron deficiency. Hyperbaric oxygen is an option for alternative rescue therapy. Most patients with chronic anemia may be discharged with follow-up if hemodynamically stable.

Abstract
Despite high prevalence of iron deficiency anemia (IDA) in patients with acute or chronic gastrointestinal bleeding (GIB), IDA and iron deficiency (ID) are frequently untreated. Reasons may be misconceptions about the impact and diagnosis of IDA and the efficacy of new treatments. Addressing these misconceptions, this article summarizes current evidence for better understanding and management of GIB-associated IDA. Despite only few controlled studies evaluated the efficacy of iron treatment in patients with GIB, there is consistent evidence suggesting that: (a) IDA should be diligently investigated, (b) effective treatment of ID/IDA improves outcomes such as health-related quality of life and can avoid severe cardiovascular consequences, and (c) intravenous iron should be considered as well-tolerated treatment in this setting. Overall, the misconceptions and practices outlined in this article should be replaced with strategies that are more in line with current guidelines and best practice in GIB and other underlying conditions of ID/IDA.

Abstract
Anemia represents one of the most frequent complications in inflammatory bowel disease (IBD) and severely impairs the quality of life of affected patients. The etiology of anemia in IBD patients can be multifactorial, often involving a combination of iron deficiency (ID) and anemia of chronic disease (ACD). Although current guidelines recommend screening for and treatment of anemia in IBD patients, current observational data suggest that it still remains underdiagnosed and undertreated. Besides basic laboratory parameters (e.g. mean corpuscular volume, reticulocyte count, serum ferritin, transferrin saturation, etc.), the concentration of soluble transferrin receptor (sTfR) and novel parameters such as the sTfR/log ferritin index can guide the challenging task of differentiating between ID and ACD. Once identified, causes of anemia should be treated accordingly. This review summarizes our current understanding of anemia in IBD patients, including the underlying pathology, diagnostic approaches and appropriate anemia treatment regimens.

Abstract
Previously undiagnosed anemia is often identified during routine assessment of surgical patients. Although studies suggest that perioperative anemia is associated with worse outcomes and a strong predictor for postoperative red cell transfusions, anemia is frequently ignored. Preoperative optimization of patients undergoing elective surgical procedures associated with significant blood loss, along with strategies to minimize intraoperative blood loss, shows promise for reducing postoperative transfusions and improving outcomes. In most situations, anemia can be corrected prior to elective surgeries and interventions. Future research should assess the timing and methods of optimization of preoperative anemia in surgery and which patients are best candidates for therapy.

Abstract
Sustained clinical cytopenia is a frequent laboratory finding in ambulatory and hospitalized patients. For pathologists and hematopathologists who examine the bone marrow (BM), a diagnosis of cytopenia secondary to an infiltrative BM process or acute leukemia can be readily established based on morphologic evaluation and flow cytometry immunophenotyping. However, it can be more challenging to establish a diagnosis of myelodysplastic syndrome (MDS). In this article, the practical approaches for establishing or excluding a diagnosis of MDS (especially low-grade MDS) in patients with clinical cytopenia are discussed along with the current diagnostic recommendations provided by the World Health Organization and the International Working Group for MDS.

Abstract
Too often anemia is considered a rare or unimportant manifestation in inflammatory bowel disease (IBD). However, over the last 10 years a number of studies have been conducted and the most relevant conclusions obtained are: (1) anemia is quite common in IBD; (2) although in many cases anemia parallels the clinical activity of the disease, many patients in remission have anemia, and iron, vitamin B12 and/or folic acid deficiency; (3) anemia, and also iron deficiency without anemia, have important consequences in the clinical status and quality of life of the patient; (4) oral iron can lead to gastrointestinal intolerance and failure of treatment; (5) intravenous iron is an effective and safe way to treat iron deficiency; (6) erythropoietin is needed in a significant number of cases to achieve normal hemoglobin levels. Thus, the clinician caring for IBD patients should have a comprehensive knowledge of anemia, and apply recently published guidelines in clinical practice.

The utility of flow cytometric immunophenotyping in cytopenic patients with a non-diagnostic bone marrow: a prospective study. Leuk Res 2009; 33:1039-46.

Abstract
Cytopenia is a common problem in hematology outpatient clinics and among hospitalized patients. A bone marrow (BM) aspirate and biopsy are often performed to rule out an infiltrative versus intrinsic BM process, such as myelodysplastic syndrome (MDS). We have previously described a flow cytometric (FCM) assay useful in diagnosing MDS and demonstrated its good correlation with "gold standard" morphologic and cytogenetic criteria. In this study, we prospectively tested the utility of the FCM assay in 102 cytopenic patients with BMs showing neither diagnostic morphological dysplasia nor abnormal cytogenetics. FCM, following our published criteria, was positive in 22 cases (21.6%), intermediate in 11 cases (10.8%) and negative in 69 cases (67.6%). With a median follow-up period of 11 months (range, 4-24 months), 12 (11.8%) patients were proven to have or/develop MDS or related BM diseases (group-1); 61 (59.8%) patients had their cytopenia(s) attributed to various medical causes (group-2). In the remaining 29 patients, the causes of cytopenia(s) were not found, and some had the features consistent with the recently defined clinical entity -- idiopathic cytopenia of uncertain significance. A positive FCM result was significantly more prevalent (9/12, 75%) in group-1 patients; while a negative FCM result was significantly more frequent in group-2 patients (4/61, 7%) (p<0.0001) with a positive predictive value of 69% and a negative predictive value of 95%. We conclude that FCM analysis of myelomonocytic maturation has diagnostic utility in cytopenic patients who have an inconclusive BM examination by morphologic and cytogenetic evaluation, and may therefore be a useful adjunct in clinical management of these patients.

Abstract
Anemia is the most common systemic complication of inflammatory bowel disease (IBD); so common that it is almost invariably not investigated and rarely treated. Several misconceptions are the reason for these clinical errors, and our goal will be to review them. The most common misconceptions are: anemia is uncommon in IBD; iron deficiency is also uncommon; just by treating the intestinal disease, anemia will be corrected; iron deficiency is the only cause for anemia in IBD; ferritin is an accurate parameter for the diagnosis of iron deficiency in IBD; the impact of anemia on the quality of life of IBD patients is limited; iron supplementation is rarely needed in IBD; high-dose oral iron solves the problem of iron malabsorption in IBD; intravenous (IV) iron is dangerous and of no proven benefit in IBD; IV iron is useful only for severe anemia; and erythropoietin has no role in the treatment of IBD anemia. These misconceptions are not evidence-based. On the contrary, there is enough evidence to support the following statements: (a) anemia is very common in IBD, (b) anemia should be investigated with care because many factors can be responsible, (c) treatment of anemia results in clear improvement in the objective parameters of well-being, especially in the quality of life, (d) IV iron is safe and effective in the treatment of iron deficiency anemia in IBD patients, and (e) erythropoietin is useful in a subset of patients with refractory anemia. Anemia diagnosis and treatment must not be neglected in IBD patients, and several misconceptions should be promptly abandoned.
