Iron Deficiency and Iron-deficiency Anemia in Toddlers Ages 18 to 36 Months: A Prospective Study

Tue, 22 Mar 2016 07:43:43 +0100

In young children, iron deficiency (ID)—the most common cause of anemia—may adversely affect long-term neurodevelopment and behavior. We prospectively evaluated the prevalence of ID and iron deficiency anemia (IDA) in 256 healthy 18- to 36-month-old children in Northern Israel. Complete blood count and ferritin evaluation were performed, and risk factors were assessed. Hemoglobin (Hgb) was compared with first-year routine screening. Complete data were obtained from 208 children: 56.2% were boys; the mean age was 26.1±5.27 months. A prevalence of 5.8% IDA, 16.3% ID without anemia, 9.6% anemia with normal ferritin, and 68.3% normal Hgb and ferritin was found. In nonanemic infants at 1 year of age (n=156), ID/IDA was found in 19.9%, and 12.8% became anemic at study evaluation. Despite ir...

Autoimmune Hemolytic Anemia in Children: Mayo Clinic Experience

Tue, 22 Mar 2016 07:43:43 +0100

We studied 35 pediatric patients with autoimmune hemolytic anemia seen at Mayo Clinic from 1994 to 2014. The median age was 10.0 years and 65.7% were males. Most had warm antibodies (80.0%) and some secondary to viral (14.3%) or autoimmune disorders (31.4%). Seven (20.0%) patients presented with Evans syndrome, 3 of whom also had common variable immunodeficiency. The median hemoglobin at diagnosis was 6.1 g/dL and 62.8% patients required red cell transfusions. The severity of anemia was worse among children below 10 years (median 5.5 vs. 7.0 g/dL, P=0.01). Steroid was the initial treatment for 88.5% patients, with overall response rate of 82.7% (68.5% complete, 14.2% partial) and median response duration of 10.7 months (range, 0.2 to 129.7+ mo). After median follow-up of 26.6 months, 8 (22...

Epstein-Barr Virus–related Posttransplant Lymphoproliferative Disorder in Children: A Single-institution Experience

Tue, 22 Mar 2016 07:43:43 +0100

We report 4 pediatric cases of biopsy-proven posttransplant lymphoproliferative disorder (PTLD) in the context of allogeneic hematopoietic stem cell transplantation (HSCT). All cases showed diffuse staining with latent membrane protein-1 in immunohistochemistry. The median age at transplant of 4 patients with PTLD was 10.1 years (range, 2.2 to 13.2 y). The median interval between HSCT and the diagnosis of PTLD was 5.5 months (range, 4 to 8 mo). All patients were treated with rituximab at dosage of 375 mg/m2 at weekly intervals. Reduction of immunosuppression was warranted in all cases. All patients survived with median follow-up duration of 27 months. Although PTLD has been rare following allogeneic HSCT, reduction of immunosuppression combined with rituximab yielded significant response r...

Identification and Clinical Characterization of Children With Benign Ethnic Neutropenia

Tue, 22 Mar 2016 07:43:43 +0100

Benign ethnic neutropenia (BEN) is an asymptomatic condition reported in adults of African and Middle Eastern descent. The clinical description in children is currently lacking. In our urban outpatient pediatric hematology clinic, the median neutrophil count of children with BEN was lower than previous reports in adults at 893×106 cells/L, but increased with older age. There was an equal male to female ratio and 24% of our BEN children reported ethnicities other than African or Middle Eastern. Children with BEN had a clinical course comparable with other healthy children including otherwise normal blood counts, except for mild anemia. (Source: Journal of Pediatric Hematology Oncology)

FDA weighs dangers of faulty readings from blood clot monitors

Mon, 21 Mar 2016 17:39:44 +0100

The FDA is considering possible dangers from medical devices that monitor blood clotting producing false readings, according to a report from The Wall Street Journal. The FDA has tracked thousands of cases of malfunctions from such devices over the years, the WSJ reports. Deaths and serious injuries have been linked with the erroneous readings, due to the increased susceptibility of individuals on anticoagulant drugs to strokes and other dangerous events. The federal watchdog brought together a panel of experts to discuss “point of care” clotting monitors last Friday to try and analyze the extent of the problem and help encourage more accurate product development, the WSJ said. The paper reported that the FDA said “serious adverse events” appear to be “linked ...

Genetic variants of GADD45A, GADD45B and MAPK14 predict platinum-based chemotherapy-induced toxicities in Chinese patients with non-small cell lung cancer.

Mon, 21 Mar 2016 05:47:03 +0100

Authors: Jia M, Zhu M, Wang M, Sun M, Qian J, Ding F, Chang J, Wei Q Abstract The JNK and P38α pathways play a crucial role in tissue homeostasis, apoptosis and autophagy under genotoxic stresses, but it is unclear whether single nucleotide polymorphisms (SNPs) of genes in these pathways play a role in platinum-based chemotherapy-induced toxicities in patients with advanced non-small cell lung cancer (NSCLC). We genotyped 11 selected, independent, potentially functional SNPs of nine genes in the JNK and P38α pathways in 689 patients with advanced NSCLC treated with platinum-combination chemotherapy regimens. Associations between these SNPs and chemotherapy toxicities were tested in a discovery group of 345 patients and then validated in a replication group of 344 patients. In bot...

Analysis of risk factors and prevalence of haemoplasma infection in dogs

Sat, 19 Mar 2016 00:00:00 +0100

This study aimed to determine the prevalence and phylogeny of canine haemoplasma species in dogs from Nigeria and describe any risk factors for infection. Canine haemoplasma species-specific and generic haemoplasma qPCR assays were used. The species-specific qPCR assays found Mhc infection in 18 of 245 dogs (7.3%), and CMhp infection in only one dog (0.4%). The generic haemoplasma qPCR assays were positive in 44 of 245 (17.9%) dogs. Twenty-five dogs had discordant qPCR results in that they were generic haemoplasma qPCR positive but species-specific qPCR negative. Further evaluation of these dogs by 16S rDNA sequencing gave limited results but 5 were confirmed to be infected with non-haemoplasma species: 2 Anaplasma phagocytophilum, 1 Anaplasma ovis, 1 Serratia marcescens and 1 Aerococcus s...

Evaluation of Anemia

Sat, 19 Mar 2016 00:00:00 +0100

Anemia is a common problem in primary care. Classification based on mean cell volume narrows the differential diagnosis and directs testing. A marked macrocytosis is characteristic of vitamin B12 and folate deficiencies, certain medications, and primary bone marrow disorders. The three most common causes of microcytic anemia are iron deficiency, thalassemia trait, and anemia of inflammation. Additional laboratory testing is required for diagnosis. Determination of the rate of development of anemia and examination of a blood smear may provide diagnostic clues to guide more specialized testing. Diagnosis of iron, vitamin B12, or folate deficiency mandates determination of the underlying cause. (Source: Obstetrics and Gynecology Clinics)

Laboratory use of hepcidin in renal transplant recipients.

Fri, 18 Mar 2016 03:28:02 +0100

Authors: Šimetić L, Zibar L Abstract Hepcidin is a small peptide with a critical role in cellular iron homeostasis, as it regulates utilization of stored iron and antimicrobial defense in inflammation (bacterial and fungal). Since it was isolated in 2000, and especially in the last decade, numerous studies aimed to evaluate the clinical use of plasma and urine hepcidin as a marker of anemia, especially anemia of chronic disease and post-transplant anemia (PTA). Hepcidin regulation is delicately tuned by two inflammatory pathways activated by interleukin-6 (IL-6) and bone morphogenic proteins (BMPs) and iron regulated pathway sensitive to circulating transferin-iron (TR-Fe) complex. BMP-mediated pathway and TR-Fe sensitive pathway seem to be connected by hemojuveline, a BMP co-fac...

Practical guidance on chronic kidney disease in cats

Fri, 18 Mar 2016 00:00:00 +0100

EXPERT guidance on the diagnosis and treatment of chronic kidney disease (CKD) in cats has been published by the International Society of Feline Medicine (ISFM). The ISFM explains that CKD is a common, complex and progressive disease which is estimated to affect more than one third of cats over 10 years of age. Cats with CKD present with a variety of clinical signs including inappetence, nausea, vomiting, anaemia, hypertension and urinary tract infections and, if the disease is not managed properly, it can severely compromise an animal's quality of life. However, the ISFM points out that the diagnosis of CKD is often not straightforward, with presenting signs varying between individual animals. There can also be problems in interpreting renal function tests. In addition, there is a lack of...

The incidence and importance of anaemia in patients undergoing cardiac surgery in the UK – the first Association of Cardiothoracic Anaesthetists national audit

Fri, 18 Mar 2016 00:00:00 +0100

Summary The importance and variability of pre‐operative anaemia in cardiac surgical patients across the UK is not known, and there is debate about its association with patient outcomes. The Association of Cardiothoracic Anaesthetists carried out its first national audit on anaemia and transfusion, and analysed data from 19,033 patients operated on in 12 cardiac surgical centres between 2010 and 2012; 5895 (31%) had pre‐operative anaemia. Centre‐specific prevalence of anaemia varied from 23% to 45%; anaemia was associated with older patients, diabetes and surgical risk (EuroSCORE). Nevertheless, controlling for these factors, regional variation remained an independent effect (p < 0.001). Multivariable analysis demonstrated an independent association of anaemia with transfusion (odd...

Perturbed MafB/GATA1 axis after burn trauma bares the potential mechanism for immune suppression and anemia of critical illness.

Fri, 18 Mar 2016 00:00:00 +0100

Authors: Johnson NB, Posluszny JA, He LK, Szilagyi A, Gamelli RL, Shankar R, Muthumalaiappan K Abstract Patients who survive initial burn injury are susceptible to nosocomial infections. Anemia of critical illness is a compounding factor in burn patients that necessitates repeated transfusions, which further increase their susceptibility to infections and sepsis. Robust host response is dependent on an adequate number and function of monocytes/macrophages and dendritic cells. In addition to impaired RBC production, burn patients are prone to depletion of dendritic cells and an increase in deactivated monocytes. In steady-state hematopoiesis, RBCs, macrophages, and dendritic cells are all generated from a common myeloid progenitor within the bone marrow. We hypothesized in a mouse m...

Relative Susceptibilities of ABO Blood Groups to Plasmodium falciparum Malaria in Ghana.

Thu, 17 Mar 2016 21:10:02 +0100

Authors: Afoakwah R, Aubyn E, Prah J, Nwaefuna EK, Boampong JN Abstract The clinical outcome of falciparum malaria in endemic areas is influenced by erythrocyte polymorphisms including the ABO blood groups. Studies have reported association of ABO blood group to resistance, susceptibility, and severity of P. falciparum malaria infection. Individuals with blood group "A" have been found to be highly susceptible to falciparum malaria whereas blood group "O" is said to confer protection against complicated cases. We analyzed samples from 293 young children less than six years old with malaria in the Korle-Bu Teaching Hospital in Accra, Ghana. It was observed that group O was present in about 16.1% of complicated cases weighed against 40.9% of uncomplicated controls. Individuals with c...

Micronutrient Supplementation after Biliopancreatic Diversion with Duodenal Switch in the Long Term

Thu, 17 Mar 2016 00:00:00 +0100

Conclusions The results of our study show that the prevalence of vitamin and mineral deficiencies after BPD-DS is 81.4 % at a minimum follow-up of 5 years. The initial prescription of micronutrient supplementation and further adjustments during the first follow-up were insufficient to avoid long-term micronutrient deficiencies. Life-long monitoring of micronutrients at a specialized bariatric center and possibly a better micronutrient supplementation, is crucial to avoid a deficient micronutrient status at every stage after malabsorptive bariatric surgery.

A Time Interval of More Than 18 Months Between a Pregnancy and a Roux-en-Y Gastric Bypass Increases the Risk of Iron Deficiency and Anaemia in Pregnancy

Thu, 17 Mar 2016 00:00:00 +0100

Conclusion A long surgery-to-pregnancy time interval after a RYGB increases the risk of iron deficiency anaemia but not of other nutritional deficits. Time interval does not seem to have an adverse effect on the obstetrical outcome, including intrauterine growth restriction. Specific attention is needed on iron deficit with increasing surgery-to-pregnancy time interval. (Source: Obesity Surgery)

Fermentation of food and feed: A technology for efficient utilization of macro and trace elements in monogastrics

A comparison of toxicity profiles between the lower and standard dose capecitabine in breast cancer: a systematic review and meta-analysis

Thu, 17 Mar 2016 00:00:00 +0100

Abstract Capecitabine 1000 mg/m2 bid × 14 days every 21 days (14/21) has been reported to have similar efficacy but more favorable toxicity profile than the approved dosage of 1250 mg/m2. However, a dose-toxicity relationship of capecitabine in breast cancer patients has not been fully elucidated. We performed a systematic review and meta-analysis to compare a safety profile between capecitabine starting dose of 1000 and 1250 mg/m2 bid. Studies were identified using PubMed, ASCO, and San Antonio Breast Cancer Symposium abstract databases through December 2015. Eligible trials included phase II/III trials of capecitabine monotherapy at 1000 or 1250 mg/m2 bid (14/21) for breast cancer patients that reported adequate safety data for all (grade 1–4) or high (grade 3–4) gr...

Early percutaneous closure of iatrogenic cardiac defects following multiple valvular surgery with direct guidewire support is a potentially curative technique with demonstrable clinical improvements

Thu, 17 Mar 2016 00:00:00 +0100

Iatrogenic cardiac defects are rare complications of valvular surgery. Reoperation is associated with increased risk of recurrent defects, morbidity and mortality [1]. Percutaneous closure with closure devices has evolved to be a clinically feasible solution and replaces the need for reoperation [2–5]. These iatrogenic defects include paravalvular leaks (PVL), ventricular septal defects and rarely, left ventricular to right atrial (Gerbode) defect. Patients develop congestive cardiac failure (CCF), haemolytic anemia and hemodynamic instability, and are often subjected to ineffective medical therapy prior to percutaneous closure.

The effect of methanolic extract of Buchanania lanzan Spreng seeds on hematological indices

Thu, 17 Mar 2016 00:00:00 +0100

Conclusions: The improvement of PCV, Hb, and RBC values is an indication of the anti-anemic effect which may be due to the stimulation of RBC production in bone marrow. Further, stimulated production of WBC could be as a result of possible stimulus of the immune system. Hence, this study confirms that the extract of B. lanzan could be useful for the treatment of anemia. (Source: Indian Journal of Pharmacology)

TRMA syndrome (thiamine-responsive megaloblastic anaemia): An example of rare monogenic diabetes: is thiamine a magic pill for anaemia and diabetes?

Thu, 17 Mar 2016 00:00:00 +0100

We report a 16-month-old male, a youngest case of genetically confirmed TRMA syndrome in Indian phenotype, born to consanguineous parents. We found a homozygous pathogenic variant in exon 2 of the SLC19A2 gene, c.314G>A (p.Gly105Glu). The anaemia showed a good response to daily thiamine doses and was able to avoid unwanted blood transfusion. There was no benefit with regard to insulin requirement. Early detection of hearing impairment and referral to audiological treatment was possible. The report indicates that TRMA should be considered as a differential diagnosis for patients presenting with suggestive clinical symptoms which would have tremendous impact on patient management if identified early.

Pomalidomide reverses {gamma}-globin silencing through the transcriptional reprogramming of adult hematopoietic progenitors

Thu, 17 Mar 2016 00:00:00 +0100

Current therapeutic strategies for sickle cell anemia are aimed at reactivating fetal hemoglobin. Pomalidomide, a third-generation immunomodulatory drug, was proposed to induce fetal hemoglobin production by an unknown mechanism. Here, we report that pomalidomide induced a fetal-like erythroid differentiation program, leading to a reversion of -globin silencing in adult human erythroblasts. Pomalidomide acted early by transiently delaying erythropoiesis at the burst-forming unit-erythroid/colony-forming unit-erythroid transition, but without affecting terminal differentiation. Further, the transcription networks involved in -globin repression were selectively and differentially affected by pomalidomide including BCL11A, SOX6, IKZF1, KLF1, and LSD1. IKAROS (IKZF1), a known target of pomalid...

An assessment of methods used in the investigation of iron status: findings in a population of young British South Asian children

Thu, 17 Mar 2016 00:00:00 +0100

Conclusions Among 205 British South Asian children aged 4–43 months with high incidences of anaemia, iron deficiency, infection and α-thalassaemia, 151 (73.6%) were classified using haemoglobin, MCH, ferritin and CRP values. In 42 non-anaemic, iron-sufficient children with subnormal MCH values, that is with a phenotype of α-thalassaemia trait, RDW, %hypo and ZPP values did not differ significantly from those with iron-deficient erythropoiesis. Raised RDW, %hypo and ZPP values should be interpreted with caution in non-anaemic young British South Asian children with microcytosis. (Source: Journal of Clinical Pathology)

Nocturnal haemoglobin oxygen desaturation in urban and rural East African paediatric cohorts with and without sickle cell anaemia: a cross-sectional study

Thu, 17 Mar 2016 00:00:00 +0100

Low haemoglobin oxygen saturation (SpO2) predicts complications in children with sickle cell anaemia (SCA) in the North but there are few data from Africa, where the majority of the patients reside. We measured daytime and overnight SpO2 in children with SCA in routine follow-up clinic, and controls without symptoms of SCA, comparing rural (Kilifi, Kenya) and urban (Dar-es-Salaam, Tanzania) cohorts. Daytime SpO2 was lower in 65 Tanzanian children with SCA (TS; median 97 (IQR 94–100)%); p<0.0001) than in 113 Kenyan children with SCA (KS; 99 (98–100)%) and 20 Tanzanian controls (TC; 100 (98–100)%).

In conclusion, vitamin D is reduced in autoimmune cytopenias and correlate with disease severity, supporting its possible protective role against the development of autoimmunity. Literature review showed vitamin D deficiency reports both in onco- and in non onco-hematologic diseases with a relationship with disease severity/activity in myeloid and lymphoid neoplasms, as well as in sickle cell disease. Supplementation has produced weak results in autoimmune and hematologic diseases, and further studies are needed. (Source: Autoimmunity Reviews)

Infant Parenteral Nutrition Remains a Significant Source for Aluminum Toxicity.

Wed, 16 Mar 2016 00:00:00 +0100

CONCLUSIONS: Aluminum contamination in infant PN remains almost 3 times higher than the advised maximum exposure (<5 mcg/kg/d, Food and Drug Administration 2004). Unexpectedly, an association between infant weight and aluminum exposure was not apparent, likely due to the homogeneity of our population. Isolating the source of aluminum contamination is difficult, as multiple components appear to be involved. Calcium gluconate is likely still a major contributor, but further investigations into individual components are warranted to promote the reduction of aluminum in infant PN.

Safety concerns about intravenous iron therapy in patients with chronic kidney disease

Tue, 15 Mar 2016 00:00:00 +0100

Anaemia in chronic kidney disease (CKD) is managed primarily with erythropoiesis-stimulating agents (ESAs) and iron therapy. Following concerns around ESA therapy, intravenous (IV) iron is being administered more and more worldwide. However, it is still unclear whether this approach is safe at very high doses or in the presence of very high ferritin levels. Some observational studies have shown a relationship between either high ferritin level or high iron dose and increased risk of death, cardiovascular events, hospitalization or infection. Others have not been able to confirm these findings. However, they suffer from indication biases. On the other hand, the majority of randomized clinical trials have only a very short follow-up (and thus drug exposure) and are inadequate to assess the m...

Karyomegalic interstitial nephritis and DNA damage-induced polyploidy in Fan1 nuclease-defective knock-in mice [Research Communications]

Tue, 15 Mar 2016 00:00:00 +0100

The Fan1 endonuclease is required for repair of DNA interstrand cross-links (ICLs). Mutations in human Fan1 cause karyomegalic interstitial nephritis (KIN), but it is unclear whether defective ICL repair is responsible or whether Fan1 nuclease activity is relevant. We show that Fan1 nuclease-defective (Fan1nd/nd) mice develop a mild form of KIN. The karyomegalic nuclei from Fan1nd/nd kidneys are polyploid, and fibroblasts from Fan1nd/nd mice become polyploid upon ICL induction, suggesting that defective ICL repair causes karyomegaly. Thus, Fan1 nuclease activity promotes ICL repair in a manner that controls ploidy, a role that we show is not shared by the Fanconi anemia pathway or the Slx4–Slx1 nuclease also involved in ICL repair.

Fan1 deficiency results in DNA interstrand cross-link repair defects, enhanced tissue karyomegaly, and organ dysfunction [Research Papers]

Tue, 15 Mar 2016 00:00:00 +0100

Deficiency of FANCD2/FANCI-associated nuclease 1 (FAN1) in humans leads to karyomegalic interstitial nephritis (KIN), a rare hereditary kidney disease characterized by chronic renal fibrosis, tubular degeneration, and characteristic polyploid nuclei in multiple tissues. The mechanism of how FAN1 protects cells is largely unknown but is thought to involve FAN1's function in DNA interstrand cross-link (ICL) repair. Here, we describe a Fan1-deficient mouse and show that FAN1 is required for cellular and organismal resistance to ICLs. We show that the ubiquitin-binding zinc finger (UBZ) domain of FAN1, which is needed for interaction with FANCD2, is not required for the initial rapid recruitment of FAN1 to ICLs or for its role in DNA ICL resistance. Epistasis analyses reveal that FAN1 has cros...

Mte1 interacts with Mph1 and promotes crossover recombination and telomere maintenance [Research Papers]

Tue, 15 Mar 2016 00:00:00 +0100

Mph1 is a member of the conserved FANCM family of DNA motor proteins that play key roles in genome maintenance processes underlying Fanconi anemia, a cancer predisposition syndrome in humans. Here, we identify Mte1 as a novel interactor of the Mph1 helicase in Saccharomyces cerevisiae. In vitro, Mte1 (Mph1-associated telomere maintenance protein 1) binds directly to DNA with a preference for branched molecules such as D loops and fork structures. In addition, Mte1 stimulates the helicase and fork regression activities of Mph1 while inhibiting the ability of Mph1 to dissociate recombination intermediates. Deletion of MTE1 reduces crossover recombination and suppresses the sensitivity of mph1 mutant cells to replication stress. Mph1 and Mte1 interdependently colocalize at DNA damage-induced ...

Lattice Boltzmann Simulation of Healthy and Defective Red Blood Cell Settling in Blood Plasma

Tue, 15 Mar 2016 00:00:00 +0100

In this paper, an attempt has been made to study sedimentation of a red blood cell (RBC) in a plasma-filled tube numerically. Such behaviors are studied for a healthy and a defective cell which might be created due to human diseases, such as diabetes, sickle-cell anemia, and hereditary spherocytosis. Flow-induced deformation of RBC is obtained using finite-element method (FEM), while flow and fluid–membrane interaction are handled using lattice Boltzmann (LB) and immersed boundary methods (IBMs), respectively. The effects of RBC properties as well as its geometry and orientation on its sedimentation rate are investigated and discussed. The results show that decreasing frontal area of an RBC and/or increasing tube diameter results in a faster settling. Comparison of healthy and diabetic c...

PIEZO1 gene mutation in a Japanese family with hereditary high phosphatidylcholine hemolytic anemia and hemochromatosis-induced diabetes mellitus.

Mon, 14 Mar 2016 00:00:00 +0100

We report here the discovery of a PIEZO1 gene mutation in a Japanese family (father, daughter, and son) who were previously diagnosed with hereditary high phosphatidylcholine hemolytic anemia (HPCHA). All of the affected family members had non-spherocytic hemolytic anemia associated with severe hemochromatosis-related diabetes mellitus. Although the causative correlation between HPCHA and PIEZO1-gene mutated HX/DHS remains to be clarified, our findings raise an important question as to whether any of the HPCHA cases previously diagnosed in Japan may have in fact been the form of hemolytic anemia known as HX/DHS with PIEZO1 gene mutation.

Carfilzomib Triple Combination Therapy: A Review in Relapsed Multiple Myeloma

Mon, 14 Mar 2016 00:00:00 +0100

Abstract Carfilzomib (Kyprolis®) is a proteasome inhibitor that binds selectively and irreversibly to the 20S proteasome (the proteolytic core particle within the 26S proteasome), inducing growth arrest and apoptosis. This intravenous drug is approved in the EU and the USA as combination therapy with oral lenalidomide and intravenous or oral dexamethasone for the treatment of patients with multiple myeloma who have received at least one prior therapy. In the multinational, phase III ASPIRE study in this patient population, carfilzomib triple combination therapy significantly prolonged progression-free survival (PFS), reflecting a clinically relevant gain in PFS of 8.7 months, compared with lenalidomide plus dexamethasone. Improvements in overall response rate and patients’ glo...

Sat, 12 Mar 2016 18:35:07 +0100

Abstract Functional iron deficiency (FID) incidence is gradually increasing in hemodialysis (HD) patients. Recently, high levels of GDF-15 supressed the iron regulatory protein hepcidin and GDF-15 expression increased in iron-deficient patients. The relationship between FID, GDF-15, and hepcidin is currently unknown. The present study aimed to evaluate the association between GDF-15, hepcidin, and FID in chronic HD patients. Serum GDF-15 and hepcidin concentrations were measured in 105 HD patients and 40 controls. FID is defined as serum ferritin >800 ng/mL, TSAT <25 %, Hb levels <11 g/dL, and reticulocyte haemoglobin content (CHr) <29 pg. Serum GDF-15 and hepcidin levels were increased significantly in HD patients with FID, compared to HD patients without anemia ...

Re-evaluation of Need for Bone Marrow Examination in Patients with Isolated Thrombocytopenia Contributors

Sat, 12 Mar 2016 18:35:07 +0100

Abstract Diagnosis of immune thrombocytopenia (ITP) is based on clinical suspicion and normal peripheral smear except for thrombocytopenia. Bone marrow examination is carried out to rule out leukemia, myelodysplastic syndrome or aplastic anemia. However, in most cases, clinical diagnosis is not altered after the bone marrow reports. Hence, this present study was carried out to evaluate the justification for bone marrow examination in the setting of isolated thrombocytopenia. All patients presenting to the hematology OPD with isolated thrombocytopenia and suspected diagnosis of ITP, between October 2011 and April 2013, were included in the study. Data was collected from bone marrow reports and outpatient records. A total of 353 cases were found. 319 cases had features of typical I...

Role of Genetic Factors in the Pathogenesis of Radial Deficiencies in Humans.

Sat, 12 Mar 2016 01:07:02 +0100

Authors: Elmakky A, Stanghellini I, Landi A, Percesepe A Abstract Radial deficiencies (RDs), defined as under/abnormal development or absence of any of the structures of the forearm, radial carpal bones and thumb, occur with a live birth incidence ranging from 1 out of 30,000 to 1 out 6,000 newborns and represent about one third/one fourth of all the congenital upper limb anomalies. About half of radial disorders have a mendelian cause and pattern of inheritance, whereas the remaining half appears sporadic with no known gene involved. In sporadic forms certain anomalies, such as thumb or radial hypoplasia, may occur either alone or in association with systemic conditions, like vertebral abnormalities or renal defects. All the cases with a mendelian inheritance are syndromic forms, ...

Drug Disposition Issues in CKD: Implications for Drug Discovery and Regulatory Approval

Sat, 12 Mar 2016 00:00:00 +0100

Publication date: March 2016 Source:Advances in Chronic Kidney Disease, Volume 23, Issue 2 Author(s): Alvin Tieu, Andrew A. House, Bradley L. Urquhart Patients with chronic kidney disease (CKD) have several comorbidities that require pharmacologic intervention including hypertension, diabetes, anemia, and cardiovascular disease. Advanced CKD patients (eg, treated with hemodialysis) take an average of 12 medications concurrently and are known to suffer from an increased number of medication-related adverse drug events. Recent basic and clinical research has identified altered renal and nonrenal drug clearance in CKD as one mediator of the increased adverse drug events observed in this patient population. This review will briefly describe pharmacokinetic considerations in CKD, review th...

The challenge of an aged and shrinking population: Lessons to be drawn from Japan’s experience

Sat, 12 Mar 2016 00:00:00 +0100

Publication date: Available online 3 March 2016 Source:The Journal of the Economics of Ageing Author(s): Peter S. Heller Japan is the first industrial country to have an aged and shrinking population. Such a demographic situation poses numerous macroeconomic and microeconomic challenges, with the former further amplified by Japan’s high public debt level. This paper underscores the multiple criteria to consider in evaluating Japan’s policies as it has approached this demographic tipping point. In examining Japan’s macroeconomic policies as well as the specifics of its social insurance policy framework, it seeks to draw lessons relevant for countries confronting the prospect of an aged population, while recognizing the importance of viewing Japan’s policies in the context of its ...

Serologically silent, occult equine infectious anemia virus (EIAV) infections in horses.

Sat, 12 Mar 2016 00:00:00 +0100

Publication date: Available online 11 March 2016 Source:Veterinary Microbiology Author(s): Sonia Ricotti, Maria Inés Garcia, Carolina Veaute, Alejandra Bailat, Eduardo Lucca, R. Frank Cook, Sheila J. Cook, Adriana Soutullo Molecular and serological techniques for Equine Infectious Anemia Virus (EIAV) diagnosis were compared using samples from 59 clinically normal horses stabled on five farms in the Santa Fe Province of Argentina. Of these 26 (44.1%) were positive in official AGID tests and/or gp45/gp90-based ELISA. Surprisingly 18 of the 33 seronegative horses were positive in a PCR against viral sequences encoding gp45 (PCR-positive/AGID-negative) with all but one remaining EIAV-antibody negative throughout a two year observation period. The gp45 PCR results are supported by fa...
