Poor bioavailability of inorganic trace elements used in broiler nutrition and their subsequent release into the environment via poultry excereta is major cause of biological and environmental concern. Hence, the need to explore the use of Chelated trace minerals in broiler diets. This study was carried out to evaluate the effect of supplemental inorganic and chelated Cu, Zn and Mn on haematology and serum biochemistry of broiler chickens. A 42-day feeding trial was conducted using a total of 300 Arbor acre broiler chickens. The birds were allocated to five dietary groups. Each group had six replicates containing 10 birds. The treatments were control (basal diet), 100% inorganic trace minerals (ITMs) supplemental level (15, 100, 100 mg/kg for Cu, Zn, Mn respectively), 50% ITMs supplemental level (7.5, 50, 50 mg/kg of Cu, Zn, Mn), 50% Chelated trace minerals (CTMs) supplemental level (7.5,50, 50 mg/kg of Cu, Zn, Mn) and 25% CTM supplemental level (3.75, 25, 25 mg/kg of Cu, Zn, Mn, in that order). A lower (p<0.05) white blood cell count (11.07x106/mm3) and an improved (p<0.05) red blood cell count (13x106/mm3) was observed for the group fed 50% CTM supplemental level. The group fed 50% supplemental level of CTM had the highest (p<0.05) total protein (73.2 g/L), albumin (41.20 g/L) and globulin (32 g/L) in serum as compared tothe other groups. The serum Cu, Zn and Mn were significantly higher (p<0.05) for the grou fed 25% supplemental diet of CTM. It can be concluded that trace minerals supplementation increased serum trace minerals of broiler chicken.

AbstractThe effects of platelet donation by apheresis on different parameters of the erythrogram are still unclear. The objective was to meta-analyze the effect of plateletpheresis on hematocrit, hemoglobin, and erythrocyte count, with a systematic review with random effects meta-analysis of the mean difference. The PRISMA guidelines were considered, as well as 133 search strategies on four different databases. Reproducibility was guaranteed and methodological quality was evaluated. Heterogeneity was evaluated with Galbraith and DerSimonian-Laird’s, publication bias with a funnel plot and a Begg’s test, sensitivity analysis and a cumulative meta-analysis were also conducted. Eighteen (18) articles were included, 17 evaluated the effects on hematocrit in 2,564 donors; 13 on hemoglobin in 1,640 donors; and 4 on red blood cell count in 243 donors. A decrease of 2.26% (CI95% = 2.11–2.41) was observed in hematocrit, of 0.80 g/dL (CI95% = 0.75–0.86) in hemoglobin and −0.21 × 1012/L (CI95% = −0.13; −0.29) in red blood cell count. Plateletpheresis has a negative effect on the erythrogram parameters, explained by blood loss in the kits used for the procedure and cell lysis. Such evidence is relevant to secure the efficiency and safety of the procedure, improve selection processes or determine the number of donations that can be performed without affecting donors’ health.

Age, sex and seasonal related changes in body weight and blood parameters were determined for T caninus and T. vulpecula, whose distribution overlapped in part of the study area. In T. caninus age-related changes occurred in body weight, mean plasma glucose and protein concentrations and haematocrit. Seasonal changes occurred in plasma glucose and protein concentrations, haemoglobin concentration and red blood cell count. There were sexual dimorphisms in haematocrit, haemoglobin concentration and red blood cell count in both species; the mean values were greater in males. T. vulpecula also exhibited a sexual dimorphism in body weight (males > females). The only seasonal change in T. vulpecula was in haemoglobin concentration. Comparison of the species as adults showed that T. caninus had higher mean levels of body weight, haematocrit and haemoglobin concentration, while plasma lipid concentration and red blood cell counts were greater in T vulpecula. These species differences may be a reflection of the diets of the two species. In addition the measured parameters showed greater seasonal variation in T. caninus, a K-selected species, than in T. vulpecula, which is more r-selected.

There is scant documentation of the stability of common haematological parameters on storage of blood samples under tropical conditions. K2EDTA samples in multiple vials were taken from 20 healthy blood donors, baseline readings taken, and stored at 33°C and 37°C. Readings from the stored vials were taken after 1, 3 and 6 h. The percent change against the baseline readings at each time point for each storage temperature was calculated. Platelet counts showed an unacceptable shift within 1 h at 37°C and 3 h at 33°C; red cell volume related parameters showed an unacceptable shift within 3 h at 37°C and 6 h at 33°C. Haemoglobin, red blood cell count, white blood cell count and mean corpuscular haemoglobin remained stable for 6 h at both temperatures. The unacceptable change for many parameters on storage at ≥33°C demonstrates the importance of ensuring pre-analytical control in regions experiencing such climatic conditions.

Background: Erythropoietin has a pivotal role in erythropoiesis and angiogenesis. A common polymorphism (rs1617640, A > C) in the promoter of the erythropoietin gene (EPO) has been associated with erythropoietin expression and microvascular complications of diabetes. We aimed to analyze the potential role of this polymorphism in the pathogenesis of peripheral arterial disease (PAD). Methods: EPO genotypes and laboratory markers for erythropoiesis were determined in 945 patients with PAD. Results: The minor EPO rs1617640 C-allele was associated in an allele-dose-dependent manner with hemoglobin levels (p = 0.006), hematocrit (p = 0.029), and red blood cell count (p = 0.003). In a multivariate linear regression analysis including conventional risk factors diabetes, sex, and smoking, EPO genotypes were furthermore associated with age at onset of PAD symptoms (p = 0.009). Conclusions: The EPO rs1617640 gene polymorphism affects erythropoiesis, leads to an earlier onset of PAD, and is a potential biomarker for the pathogenesis of this disease.
