OBJECTIVE: The natural history of type II endoleak (T2EL) after endovascular aneurysm repair (EVAR) for ruptured abdominal aortic aneurysm (rAAA) remains elusive; as such, treatment guidelines are ill defined. The purpose of this study was to better delineate the natural history of T2EL after EVAR for rAAA in an effort to determine the need for reintervention and optimal surveillance. METHODS: A retrospective record review was conducted of all patients undergoing EVAR for rAAA in two large tertiary care academic vascular centers...

BACKGROUND: ADAMS(™) A1cHA-8180T is a HPLC system; within 3.5 min, it quantifies HbF, HbA2 , and HbA0 and flags abnormal peaks. We evaluate its analytical performance for routine estimation of HbA2 and HbF, and critical tests were performed for identifying β-thalassemia carriers. METHODS: Trueness imprecision, carry over, linearity, and effect of anemia were evaluated according to ICLH, ICLS, or manufacture's guidelines. Comparison (ADAMS(™) A1c HA-8160T) was performed by running 400 samples from healthy subjects, 30 alpha and 80 beta carriers (range: 1...

Anemia is a frequent complication in cancer patients, both at diagnosis and during treatment, with a multifactorial etiology in most cases. Iron deficiency is among the most common causes of anemia in this setting and can develop in nearly half of patients with solid tumors and hematologic malignancies. Surprisingly, this fact is usually neglected by the attending physician in a way that proper and prompt investigation of the iron status is either not performed or postponed. In cancer patients, functional iron deficiency is the predominant mechanism, in which iron availability is reduced due to disease or the therapy-related inflammatory process...

OBJECTIVE: Alpha thalassemia major (ATM) is often fatal in utero due to severe hydrops fetalis. Although in utero transfusions (IUT) are increasingly used to allow fetal survival in ATM, pre- and postnatal outcomes are not well described. METHODS: We retrospectively reviewed cases of ATM at our institution treated with consecutive IUT. Clinical records were reviewed for transfusion history, neurodevelopmental outcomes, anatomic abnormalities, survival to hematopoietic cell transplantation and transfusion independence...

BACKGROUND: Although chronic kidney disease (CKD) affects a growing number of people, epidemiologic data on incident CKD in the general population are scarce. Screening strategies to increase early CKD detection have been developed. METHODS: From a community-based sample of 4,409 individuals residing in a well-defined geographical area, we determined the number of patients having a first serum creatinine value ≥1.7 mg/dL and present for at least 3 months that allowed us to calculate an annual incidence rate of CKD (stages 3 to 5)...

Acquired aplastic anemia (AA) and paroxysmal nocturnal hemoglobinuria (PNH) are interrelated ultra-rare diseases. Quality of life (QoL) evaluation tools used in studies for AA and PNH are unspecific and designed for cancer patients (e.g., the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire, EORTC QLQ-C30). Given the complexity of AA and PNH, variation in symptoms and treatments, younger age of many patients, and the fact that AA and PNH are not classified as malignant diseases, it is likely that cancer-specific questionnaires are inappropriate...

OBJECTIVES: Three are no clinical practice guidelines that specifically address the management of patients with iron deficiency anemia (IDA) in the emergency department (ED). The goal of this study was to describe the characteristics of IDA patients who present to the ED, documentation of IDA by emergency physicians, utilization of iron supplementation, and the appropriateness of red blood cell (RBC) transfusions ordered in the ED. METHODS: A retrospective medical chart review was performed of IDA patients who visited the ED of a large tertiary center over a three-month period...

BACKGROUND: Currently, the standard management of moderate aplastic anemia (MAA) has not been well described, although the superiority of the combination of antithymocyte globulin (ATG) and cyclosporine (CyA) over CyA alone has been demonstrated in terms of hematological responses and failure-free survival (FFS). PROCEDURE: We adopted this therapeutic strategy and treated 95 children with MAA who were enrolled in two consecutive prospective studies between October 1992 and August 2009...

Anemia is an independent risk factor for adverse patient outcomes. There are no guidelines for management of anemia in patients withcongestive heart failure (CHF), despite itshigh incidence. Four objectives were defined by the International Anemia Management and Clinical Outcomes Expert Panel (AMCO), a multinational group of interdisciplinary experts identified by the Society for the Advancement of Blood Management (SABM) to: determine the prevalence of anemia in outpatients; to determine the prevalence of hospital-acquired anemia; to assess the impact of anemia management on clinical outcomes such as quality of life and functional status; and to provide recommendations for primary care physicians and specialists for the diagnosis, evaluation, and management of anemia in patients with CHF...

BACKGROUND Thrombotic thrombocytopenic purpura (TTP) is one of the thrombotic microangiopathic (TMA) syndromes, caused by severely reduced activity of the vWF-cleaving protease ADAMTS13. Systemic lupus erythematosus (SLE), on the other hand, is an autoimmune disease that affects various organs in the body, including the hematopoietic system. SLE can present with TMA, and differentiating between SLE and TTP in those cases can be very challenging, particularly in patients with no prior history of SLE. Furthermore, an association between these 2 diseases has been described in the literature, with most of the TTP cases occurring after the diagnosis of SLE...

This systematic review evaluates the effectiveness of delayed cord clamping in preterm infants on reducing postdelivery complications of anemia, hemodynamic instability, and the development of intraventricular hemorrhages. Interventions included varying durations of delayed cord clamping with and without cord milking as compared with immediate cord clamping, shorter delays in cord clamping, and delayed cord clamping without cord milking. A comprehensive search of randomized controlled trials, observational, cohort, and before-after studies was conducted between 1946 and 2015 in the electronic databases of Ovid MEDLINE, Embase, and Google Scholar...

The hematocrit (Hct) determines the oxygen carrying capacity of blood, but also increases blood viscosity and thus flow resistance. From this dual role the concept of an optimum Hct for tissue oxygenation has been derived. Viscometric studies using the ratio Hct/blood viscosity at high shear rate showed an optimum Hct of 50-60% for red blood cell (RBC) suspensions in plasma. For the perfusion of an artificial microvascular network with 5-70μm channels the optimum Hct was 60-70% for high driving pressures. With lower shear rates or driving pressures the optimum Hct shifted towards lower values...

Iron deficiency (ID) has been identified as an important co-morbidity in patients with heart failure (HF). Intravenous iron therapy reduced symptoms and rehospitalizations of iron-deficient patients with HF in randomized trials. The present multicenter study investigated the "real-world" management of iron status in patients with HF. Consecutive patients with HF and ejection fraction ≤40% were recruited and analyzed from December 2010 to October 2015 by 11 centers in Germany and Switzerland. Of 1,484 patients with HF, iron status was determined in only 923 patients (62...

Cardiovascular (CV) risk assessment is not easy in chronic kidney disease (CKD) patients. Age, male sex, race, family history of CV disease, smoking status and diabetes should be considered as CV risk factors as the general population. It is also accepted that hypertension (HTN) is associated with the greater risk of CV complications in this population. However, there are some concerns in this issue.First, supporting evidence for specific blood pressure (BP) targets in CKD is scarce. Many observational studies reported a J-shaped association between BP level and CV mortality unlike a linear association in the general population...

BACKGROUND: Anemia is a common complication among patients with inflammatory bowel diseases (IBD) and is associated with high rates of IBD-related complications, resource utilization, and impaired quality of life. Despite practice guidelines for anemia in patients with IBD, gaps remain in the perceptions of anemia among health care providers. The aims of this study were to identify gaps in care and to develop a care pathway for anemia in patients with IBD. METHODS: The Crohn's & Colitis Foundation of America anemia care pathway was developed by a committee using principles of cognitive task analysis...

Importance: More than 100 million units of blood are collected worldwide each year, yet the indication for red blood cell (RBC) transfusion and the optimal length of RBC storage prior to transfusion are uncertain. Objective: To provide recommendations for the target hemoglobin level for RBC transfusion among hospitalized adult patients who are hemodynamically stable and the length of time RBCs should be stored prior to transfusion. Evidence Review: Reference librarians conducted a literature search for randomized clinical trials (RCTs) evaluating hemoglobin thresholds for RBC transfusion (1950-May 2016) and RBC storage duration (1948-May 2016) without language restrictions...

Polycythemia vera (PV) is an acquired clonal hematopoietic stem cell disorder characterized by an overproduction of red blood cells, white blood cells, and platelets; thrombotic and hemorrhagic complications; and an increased risk of transformation to myelofibrosis and acute leukemia. In 1967, the Polycythemia Vera Study Group proposed the optimal approach to diagnosis and treatment of PV, and in 2002, investigators from Johns Hopkins University School of Medicine surveyed the practice patterns of hematologists as they pertained to PV...

Adults with homozygous sickle cell anemia have, on average, lower cognitive function than unaffected controls. The mechanisms underlying cognitive deterioration in this population are poorly understood, but cerebral small vessel disease (CSVD) is likely to be implicated. We conducted a systematic review using the Prisma Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines of articles that included both measures of cognitive function and magnetic resonance imaging (MRI) neuroimaging markers of small vessel disease...
