AbstractThe effect of radiofrequency exposure on human health and health care equipment is a matter of ongoing debate. This study was planned to investigate the influence of radiofrequency (RF) waves emitted by a commercial mobile phone on red blood cells (RBC) in vitro.The study population consisted of 16 ostensibly healthy volunteers. Two whole blood specimens were collected from each volunteer. One sample was placed in a plastic rack, 1 cm distant from the chassis of a commercial mobile phone which was activated by a remote phone call lasting 30 min. The other blood sample was placed in another plastic rack, but was kept distant from any type of RF source. The main RBC parameters including RBC count, hematocrit (Ht), hemoglobin, mean corpuscular platelet volume (MPV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC) and RBC distribution width (RDW-CV) were assessed with an Advia 2120.The exposure of whole blood to the mobile phone call significantly increased Ht, hemoglobin, MCV and MCH, whereas the RBC count, MCHC and RDW-CV remained unchanged. A significant correlation was observed between variation of Ht and those of hemoglobin (p=0.008), MCV (p=0.009) or MCH (p=0.037), as well as between hemoglobin and MCV (p=0.048). Increased values were found in 13/16 (81%) samples for both Ht and hemoglobin, 14/16 (88%) samples for MCH and 16/16 (100%) samples for MCV.These results suggest that close mobile phone exposure may be an unappreciated and possibly underestimated cause of preanalytical bias in RBC testing.

Lung Lesions

Abstract Developments of pulmonary diseases, often accompanied by infections of bacteria, severely affect the meat production and welfare of pigs. This study investigated 307 pigs at age of 240 d from an eight-breed cross reared under standardized housing conditions for associations among the extent of lung lesions, bacteria load inferred from 16S rRNA sequencing of bronchoalveolar lavage fluid, as well as 57 immune cells and 25 hematological traits. We showed that the pigs under study suffered substantial and varied lung lesions, and the Mycoplasma is the most associated bacteria genera. At a false discovery rate of 0.05 (FDR < 0.05), the severity of lung lesions were significantly associated with greater CD8+ to CD3+ cell ratio, neutrophil-to-lymphocyte ratio (NLR), and standard deviation of red blood cell volume distribution width (RDW-SD), and lower CD4−CD8−/CD3+, CD3+CD4−CD8−/PBMCs (peripheral blood mononuclear cells) and CD14−CD16−/PBMCs cell ratios, mean corpuscular hemoglobin concentration, lymphocyte count, and lymphocyte count percentage, reflecting an status of inflammation, immune suppression, and hypoxia of the pigs accompanying the progression of the lung lesions. The Mycoplasma abundance showed positive correlations with neutrophil count, neutrophil count percentage, NLR, monocyte count, coefficient of variation in red blood cell volume distribution width , and RDW-SD, and negative correlations with mean corpuscular hemoglobin concentration, lymphocyte count, and lymphocyte count percentage; these correlations are largely consistent with those of lung lesions, supporting the comorbidity of lung lesions and Mycoplasma infection. We also observed nonlinear associations that sharp increases in neutrophil count and neutrophil count percentage occurred only when Mycoplasma abundance raised above the population-average level. The results provide helpful insights into the changes of host immune status in response to Mycoplasma relevant lung diseases in pigs.

The aim of this study was to examine the effects of resistance training on hematological blood markers in older individuals. Twenty-nine men and women participated to this study. Subjects were randomized in 2 groups: (1) control (n=13) and (2) resistance training (n=16). At baseline and after the intervention, subjects were submitted to a blood sample to determine their hematological profile (red blood cells, hemoglobin, hematocrit, platelets, leukocytes, neutrophils, lymphocytes, monocytes, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, red cell distribution width). At baseline, no difference was observed between groups. Moreover, we found no significant difference after the intervention on any of these markers. A 6-month resistance program in healthy older individuals seems to have no beneficial nor deleterious effects on hematological blood parameters. However, resistance training was well tolerated and should be recommended for other health purposes. Further studies are needed to confirm these results in a large population.

Blood was analyzed from eighty (forty males and forty females) adult individuals ofPolypedates teraiensisto establish reference ranges for its hematological and serum biochemical parameters. The peripheral blood cells were differentiated as erythrocytes, lymphocytes, eosinophils, neutrophils, monocytes, basophils, and thrombocytes, with similar morphology to other anurans. Morphology of blood cells did not vary according to sex. The hematological investigations included morphology and morphometry of erythrocytes, morphometry of leucocytes, packed cell volume (PCV), hemoglobin content (Hb), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), erythrocyte or red blood cell (RBC) count, leukocyte or white blood cell (WBC) count, differential leukocyte count, and neutrophil to lymphocyte (N/L) ratio. Besides, protein, cholesterol, glucose, urea, uric acid, and creatinine content of blood serum were assayed. Hematological parameters that differed significantly between sexes were RBC count, length and breadth of RBC, neutrophil %, N/L ratio, area occupied by basophils, and diameter of large lymphocyte and eosinophils. The level of glucose, urea, and creatinine in blood serum also significantly differed between sexes.

Aim. The aim of the study was to assess markers of anemia in type 1 diabetes (T1D) children, compare them to results obtained in the control group, and estimate their relation to BMI SDS. Methods. 94 (59% ♀) T1D children without other autoimmune disorders, aged 12.5 ± 4.1 years, T1D duration: 4.2 ± 3.6 years, HbA1c 7.3 ± 1.5% (57 ± 12.6 mmol/mol). Sex- and age-matched controls (43 children). In all children, anthropometric measurements, the blood count, iron turnover parameters, and vitamin B12 concentration were taken. Results. T1DM children had significantly higher red cell distribution width (RDW) (13.6 versus 12.6%; p<0.001), hepcidin (0.25 versus 0.12 ng/ml; p<0.001), and vitamin B12 concentrations (459 versus 397 pg/ml; p<0.01) and lower TIBC (59.09 versus 68.15 μmol/l; p<0.001) than in the control group. Logistic regression revealed that RDW, TIBC (both p<0.001), and hepcidin (p<0.05) significantly differentiated both groups. In T1DM children, BMI SDS negatively correlated with vitamin B12 (p<0.01) concentration and mean corpuscular hemoglobin concentration (p<0.05) and positively with TIBC (p<0.01) and HbA1c (p<0.001). Conclusions. Patients and controls differed especially in terms of RDW and TIBC. In studied T1DM children, BMI SDS was associated to iron metabolism parameters and vitamin B12 concentration.

Background: During viral outbreaks, pregnancy poses an increased risk of infection for women. Methods: In a prospective study, all patients admitted for delivery at term to Elena Doamna Obstetrics and Gynecology University Hospital in Iasi, Romania, between 1 April 2020 and 31 December 2020 were included. There were 457 patients, divided into two groups: group 1, SARS-CoV-2-positive patients (n = 46) and group 2, SARS-CoV-2-negative patients (n = 411). Among other tests, complete blood count was determined upon admittance, and the following values were studied: white blood cell count, lymphocytes, neutrophils, red blood cell count, hemoglobin, mean corpuscular hemoglobin concentration, mean corpuscular hemoglobin, mean corpuscular volume, red blood cell distribution width, hematocrit, platelet count, mean platelet volume, platelet distribution width, plateletcrit, and platelet large cell ratio. Results: in pregnant SARS-CoV-2-infected patients at term, there was a significant decrease in white blood cell, neutrophil, and lymphocyte count, and an increase in mean corpuscular hemoglobin concentration, compared to healthy pregnant women at term, although all still within normal limits. None of the other components of the complete blood count or fetal outcomes studied was significantly influenced by SARS-CoV-2 infection in pregnant patients at term.

ABSTRACT Objective: To assess the efficacy of a peripheral smear examination as a screening tool for β-thalassemia trait. Materials and Methods: 17 623 Leishman-stained peripheral smears were evaluated during the period from July 2006 to September 2007. The following parameters were studied: hemoglobin, red blood cell count, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration and red cell distribution width. All the cases that showed microcytosis, hypochromia, erythrocytosis and absence of anisopoikilocytosis were suspected of having the thalassemia trait (TT), and all these cases were further evaluated with Alkaline Hemoglobin Electrophoresis for confirmation. Results: Of the 17 623 smears examined, 60 cases were considered suspicious of having TT. Alkaline hemoglobin electrophoresis carried out on all these cases revealed an elevated HbA 2 (Mean = 7.5%). Five cases evaluated were found to have other hemoglobinopathies (1 Sickle cell trait, 3 Hb-E, 1 thalassemia intermedia). Conclusion: Careful screening of peripheral smear is an invaluable screening tool for thalassemia trait (PPV - 95%). There must be awareness among the peripheral centers about the importance of peripheral smear screening and the affected persons should be counseled.

Abstract A patient with multiple myeloma had an automated blood count performed on a Coulter STK-S counter that repeatedly failed internal limits for both mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration. The calculated hematocrit agreed with a spun hematocrit, suggesting that the hemoglobin concentration was being overestimated by the automated counter. Measurement of the plasma hemoglobin concentration of the sample, which showed no visible hemolysis, gave a hemoglobin concentration of 32 g/L on the STK-S analyzer. Correction of the whole blood hemoglobin using the plasma hemoglobin gave a value consistent with the hematocrit. The corrected mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration values were within standard limits. This patient's paraprotein was characterized as IgA-κ and was present at a concentration of 61 g/L. The hemoglobin concentration measured on whole blood by Sysmex NE 8000 and Technicon H*1E autoanalyzers agreed reasonably well with the corrected result from the STK-S.

Adipose tissue produces several adipokines that are enrolled in different metabolic and inflammatory pathways that may disturb iron metabolism and erythropoiesis. Considering that laparoscopic adjustable gastric banding (LAGB) has not been associated with a long-term risk of malabsorption, we performed a 13-month follow-up study in severe obese patients submitted to LAGB in order to clarify its impact on inflammation, iron metabolism and on red blood cell (RBC) biomarkers. Twenty obese patients were enrolled in the study, being clinical and analytically assessed before (T0) and 13 months after LAGB intervention (T1). Inflammation, iron bioavailability and RBC biomarkers were evaluated at T0 and T1. At T1, weight and anthropometric indices decreased significantly; patients showed a significant increase in mean corpuscular volume, mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration (MCHC), and a reduction in red cell distribution width, ferritin, hepcidin, tumor necrosis factor-α, interleukin-6 (IL-6) and C-reactive protein. Before LAGB, IL-6 correlated negatively with iron, hemoglobin concentration and MCHC; hepcidin correlated inversely with transferrin. Our data show that 13 months after LAGB, the weight loss is associated with an improvement in inflammation, namely a reduction in IL-6 that may reduce hepcidin production, improving iron availability for erythropoiesis, as shown by more adequate erythrocyte hemoglobinization.

Abstract Objectives In this study we want to investigate the effects of Q-CAN® Plus, the nutritional fermented soy drink on the hematological parameters in lean and obese individuals. Methods Prospective study comprised of lean (10) and obese (10) individuals without a known diagnosis. 11 clinic visits over 14 weeks (visit 1/wk −2, visit 2/wk −1, visit 3/wk 0, visit 4/wk 1, visit 5/wk 2, visit 6/wk 3, visit 7/wk 4, visit 8/wk 6, visit 9/wk 8, visit 10/wk 10, visit 11/wk 12). Visits 1, 2 and 3 occurred prior to treatment. 237 ml of soy was dispensed at visit 3 and was consumed twice daily for 4 weeks until visit 7 (weeks 1–4). Visits 8, 9, 10 and 11 were post treatment. Blood was collected during visits 1, 3, 5, 7, 8, 9, 10,11, and various hematological parameters were quantified at Yale New haven health, hematology lab at the Department of laboratory medicine (Yale new haven health, Yale University, CT, USA). The values were statistically analyzed using one-way ANOVA and the results were considered significant for P < 0.05. Results Various blood indices such as mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), mean corpuscular volume (MCV), mean platelet volume (MPV), red blood cell distribution width (RDW-CV), hematocrit, RBC count, WBC count, % neutrophils, average number of neutrophils (# neutrophils), % monocytes, % basophils, average number of lymphocytes (# lymphocytes), % eosinophils and C- reactive protein were analyzed. These values were compared as plot curve for values from individual visits of each subject, as averages of combined values of both lean and obese individuals grouped as (pre, during and post) treatment periods of BESO soy drink, as averages of lean vs obese grouped for various treatment periods of BESO soy drink and as ratio of averages of lean vs obese group values for various treatment periods of BESO soy drink. The consumption of Q-CAN® Plus did not result in significant changes in any hematological parameters Conclusions Q-CAN® Plus fermented soy drink does not induce any significant change in the hematological parameters of both lean and obese individuals. These observations demonstrate the safety of Q-CAN® Plus regarding hematological parameters in lean and obese individuals. Funding Sources Beso Biological Research, Inc.
