BACKGROUND: Bariatric surgery has increased in popularity, with Roux-en-Y Gastric Bypass (RYGB) being one of the most frequently performed. This leads to many cases in which the stomach is removed from routine gastroscopy access, sometimes being a major source of concern. Performing enteroscopy in these patients is technically difficult. We present our experience with 24 cases in which the aim was to access the detached stomach. METHODS: Retrospective analysis on RYGB enteroscopy procedures aimed to access the detached stomach...

S Paul Starr
Biologics are substances made from a living organism or its products. These include genes, proteins (eg, antibodies, receptors, enzymes, inhibitors), recombinant proteins, and fusion proteins. Biologics often are produced using recombinant DNA technology. For example, monoclonal antibodies are produced by inserting human genes into immortalized cell cultures, which then produce the gene product (ie, an antibody) in large quantity. Another approach is to fuse genetic material from nonhuman sources (eg, mice) with human genetic material...

The aim of this meta-analysis was to evaluate the effect of peritoneal dialysis (PD) and hemodialysis (HD) on renal anemia (RA) in renal disease patients by a meta-analysis. Relevant studies published before June 2015 were searched. Pooled odds ratio (OR) with 95% confidence interval (CI) was used to evaluate the effect of HD and PD on RA based on five indexes: hemoglobin, ferritin, transferrin saturation index, serum albumin, and parathyroid hormone. Sensitivity analysis and publication bias assessment were conducted to evaluate the stability and reliability of our results...

In the past two decades public interest in herbal products has increased significantly in Europe, especially in the plant-based products from non-European traditions. Eleutherococcus senticosus has been used for the treatment of inflammatory diseases, anemia, and rheumatoid arthritis. The Eleutherococcus senticosus fruits intractum was examined for the content of phenolic acids (LC-ESI-MS/MS), minerals (AAS), TPC, and TFC (spectrophotometric assay). The antioxidant activity was determined using free radical scavenging assay and TLC-DB-DPPH(∗) dot-blot test...

The myelodysplastic/myeloproliferative neoplasms (MDS/MPNs) are a unique group of hematologic malignancies characterized by concomitant myelodysplastic and myeloproliferative features. According to the 2008 WHO classification, the category includes atypical chronic myeloid leukemia (aCML), chronic myelomonocytic leukemia (CMML), juvenile myelomonocytic leukemia (JMML), MDS/MPN-unclassifiable (MDS/MPN-U), and the provisional entity refractory anemia with ring sideroblasts and thrombocytosis (RARS-T). Although diagnosis currently remains based on clinicopathologic features, the incorporation of next-generation platforms has allowed for the recent molecular characterization of these diseases which has revealed unique and complex mutational profiles that support their distinct biology and is anticipated to soon play an integral role in diagnosis, prognostication, and treatment...

The term "refractory anemia" was used in 1937 by Cornelius Parker Rhoads to describe patients whose anemia did not improve after treatment with liver extract or iron salts, and this term has been used to denote patients with certain subtypes of myelodysplastic syndromes (MDS) since the 1976 and 1982 French-American-British (FAB) classifications of acute leukemias and MDS. In 2016, the World Health Organization (WHO) proposed elimination of "refractory anemia" in a more general proposal for reclassification of myeloid neoplasia...

Kidney transplant recipients are at increased risk of developing clinical disease due to uncommon opportunistic viral pathogens. Refractory anemia is classically associated with parvovirus B19 infection. West Nile virus has the propensity to cause fever and neurologic symptoms, while spastic paresis and lymphoma can be triggered by human T cell lymphotrophic virus. In this review article, the epidemiology, clinical manifestations, diagnosis and treatment of less common viruses are discussed in the setting of kidney transplantation...

The incidence of SF3B1 mutations in patients with RARS is high. Recently, it has been shown that SF3B1 and DNMT3A mutations overlap more often than expected, although it is not clear how this could affect the disease. We studied SF3B1 and DNMT3A in 123 RARS patients: 101 out of 123 samples (82%) had somatic mutations in SF3B1, and 13 of them (13%) showed a co-mutation (SF3B1(mut)DNMT3A(mut)). All co-mutated patients had a normal karyotype, and 12 of them (92%) were lower-risk patients (IPSS and IPSS-R). Despite their favorable profile, SF3B1(mut)DNMT3A(mut) patients showed a higher RBC transfusion dependency (92% versus 48%, p = ...

INTRODUCTION: Megaloblastic anemia (MA) represents a subtype of macrocytic anemia caused by impaired DNA synthesis, mostly due to folate and vitamin B12 deficiency. Its mildest forms lead to macrocytosis without concomitant anemia, but more severe forms to thrombocytopenia and/or leucopenia as well. In majority of the cases, the diagnosis of MA dose not represent a serious clinical problem, however, other causes of macrocytosis including myelodysplastic syndrome (MDS) must be excluded...

Anemia often develops in rheumatoid arthritis (RA) patients. In the present study, we examined the association between the therapeutic effectiveness of the biologic agent tocilizumab (TCZ) and potential predictors of therapeutic effectiveness. We focused on the amelioration of anemia of chronic inflammation through the mechanism of direct inhibition of Interleukin (IL)-6 receptor-mediated signals by TCZ. Serum hepcidin-25, which is expressed in an IL-6 dependent manner and is a major cause of anemia of chronic inflammation, was measured in 10 RA patients, before and after administration of TCZ...

In comparison with the 2008 World Health Organization "Blue Book" on hematopoietic neoplasms, a small number of changes have been made in the classification. In the lower-risk patients, Refractory Cytopenias with Multilineage Dysplasia and Ring Sideroblasts (RCMD-RS) has been separated from RCMD to recognize the importance of the SF3B1 mutation. Often there has been confusion as to the degree of morphologic dysplasia and/or cytopenias to define some of the lower-risk subtypes. In addition, the type of dysplasia or cytopenias is not always concordant...

Variants in ETV6, which encodes a transcription repressor of the E26 transformation-specific family, have recently been reported to be responsible for inherited thrombocytopenia and hematologic malignancy. We sequenced the DNA from cases with unexplained dominant thrombocytopenia and identified six likely pathogenic variants in ETV6, of which five are novel. We observed low repressive activity of all tested ETV6 variants and variants located in the E26 transformation-specific binding domain (encoding p.A377T, p...

More than 80% of patients with the refractory anemia with ring sideroblasts subtype of myelodysplastic syndrome (MDS) have mutations in Splicing Factor 3B, Subunit 1 (SF3B1). We generated a conditional knockin mouse model of the most common SF3B1 mutation, Sf3b1(K700E). Sf3b1(K700E) mice develop macrocytic anemia due to a terminal erythroid maturation defect, erythroid dysplasia, and long-term hematopoietic stem cell (LT-HSC) expansion. Sf3b1(K700E) myeloid progenitors and SF3B1-mutant MDS patient samples demonstrate aberrant 3' splice-site selection associated with increased nonsense-mediated decay...
