RESUMO

ABSTRACT Introduction: During pregnancy, the iron requirement increases to meet the optimal growth of the fetus and prevent iron deficiency anemia-related complications in the mother. However, in sickle cell disease (SCD) primarily due to repeated blood transfusions and hemolysis-induced recycling of iron, its supplementation during pregnancy remains questionable and may be harmful. Methods: Twenty-five pregnant women with homozygous SCD and 25 pregnant women with normal hemoglobin variants were included as cases and control, respectively. Pregnancy and sickle cell anemia (SCA) were diagnosed using standard protocols. The serum iron, serum ferritin, total iron-binding capacity (TIBC), percentage transferrin saturation and C-reactive protein were estimated, as per the manufacturer's protocol. The complete blood count was performed. The unpaired 't-test' was performed using the SPSS v23.0 and the principal component analysis (PCA) was performed using the online software MetaboAnalyst for statistical analysis. Main Results: The studied cases had significantly lower mean hemoglobin and higher mean corpuscular volume (MCV), compared to controls. The mean serum-iron, serum-ferritin and percentage transferrin-saturation in the cases were significantly higher than that of the controls, while the TIBC was lower in the cases (p < 0.0001). The mean level of serum iron, ferritin, percentage transferrin saturation and TIBC were 309.44 ± 122.40mcg/dl, 860.36 ± 624.64ng/ml, 42.6 ± 17.30% and 241.32 ± 96.30 mcg/dl, respectively, in the cases and 95.36 ± 41.90mcg/dl, 122.28 ± 49.70ng/ml, 15.83 ± 3.10% and 492.6 ± 149.40mcg/dl in the controls, respectively. Higher MCV, mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) with lower hemoglobin (Hb) were noted in the cases. The PCA revealed that the cases were more heterogeneous in terms of the variability of the iron status and hematological indices than the controls. Conclusion: The current study shows iron sufficiency in most cases of pregnancy with SCA and suggests that evaluation of iron status must be made before initiating iron prophylaxis in pregnant women with SCA, especially in regions having a high prevalence of sickle cell hemoglobinopathy.

RESUMO

Introducción: El síndrome metabólico se ha asociado con cambios en parámetros hematológicos (glóbulos rojos, plaquetas y leucocitos); se pueden utilizar para identificar sujetos en riesgo de fenotipos metabólicamente no saludables (MUP). Se investigó si estos parámetros hematológicos sirven como biomarcadores para distinguir el fenotipo metabólicamente sano (MHP) del MUP en niños y adolescentes. Métodos: Estudio transversal, 292 niños y adolescentes. El diagnóstico de MUP fue según consenso. Se utilizó ANOVA unidireccional en las comparaciones, regresión logística múltiple para determinar si el sexo, el grupo etario, el estado nutricional, la pubertad, los parámetros hematológicos y la resistencia a la insulina se asociaron con MUP. Resultados: Edad media 11 años (DE: 2,61). Los valores de RDW fueron significativamente más bajos en los niños en el grupo de peso normal metabólicamente insalubre (MUNW) en comparación con los niños con obesidad metabólicamente no saludable (MUO) (12,33 ± 0,90 vs. 13,67 ± 0,52; p = 0,01) y en la obesidad metabólicamente saludable (MHO) en comparación con el grupo MUO (13,15 ± 0,53 vs. 13,67 ± 0,52; p = 0,04). En adolescentes, la relación plaquetas/linfocitos fue mayor en el grupo MHNW (con un valor medio de 152,60 (DE 62,97) vs 111,16 (DE 44,12) para el grupo MHO. Al ajustar por edad, estado nutricional y pubertad, los índices hematológicos no se asociaron con MUP. Conclusión: Los parámetros hematológicos no están asociados independientemente con el MUP, y es poco probable que representen biomarcadores confiables para la detección del MUP en la población pediátrica.


Introduction: Metabolic syndrome has been associated with changes in several hematological parameters, such as red blood cells, platelets, and leucocytes. Therefore, hematologic parameters can be used to identify the subjects at risk of metabolically unhealthy phenotypes (MUP). The current study investigated if hematological parameters can serve as biomarkers to distinguish metabolically healthy phenotype (MHP) from MUP in children and adolescents. Methods: Two hundred ninety-two children and adolescents were enrolled in this cross-sectional study. The MUP was diagnosed using consensus-based criteria. Group comparisons were performed using one-way ANOVA. Multiple logistic regression analysis was used to determine if sex, age group, nutritional status, puberty, hematological parameters, and insulin resistance were associated with MUP. Results: The subject's age mean was 11 years (SD: 2.61). RDW values were significantly lower in children in the metabolically unhealthy normal weight (MUNW) group compared to children with metabolically unhealthy obesity (MUO) group (12.33 ± 0.90 vs. 13.67 ± 0.52; p = 0.01) and in metabolically healthy obesity (MHO) compared to MUO group (13.15 ± 0.53 vs. 13.67 ± 0.52; p = 0.04). In adolescents, the platelet-to-lymphocyte ratio was higher in the MHNW group, with a mean value of 152.60 (SD 62.97) compared to 111.16 (SD 44.12) for the MHO group. However, after adjusting for age, nutritional status, and puberty, hematological indices were not associated with MUP. Conclusions: The study demonstrates that hematologic parameters are not independently associated with the MUP, and it is unlikely that they represent reliable biomarkers for screening for the MUP in the pediatric population.

RESUMO

Objective To examine hematological and biochemical parameters in 30 common marmosets,count the mean and standard deviations of each index, and analyze significant differences between female and male groups. Additionally,data from marmosets and macaque breeding were compared. Methods Blood was collected through the posterior limb vein while animals were awake. Hematology and serum biochemical indices were then measured with an automatic blood cell analyzer and blood biochemical analyzer, followed by statistical testing. Results No significant differences were measured in hematological indices between male and female groups. There was a significant difference between the female and male group in serum biochemical indices including high-density lipoprotein-cholesterol(HDL-C) and low-density lipoprotein-cholesterol(LDL-C)(P < 0.05). Compared with the foreign marmoset group, HGB, MCHC,NEUT,ALT, AST, and GLOB were visibly increased in the group of marmosets fed by our institution, but in accordance with the data range in rhesus monkeys. Conclusions Hematological and serum biochemical indices of common marmosets have been detected in this study and compared with related data in macaques and marmosets. Our findings provide basic data not only for pharmacological and toxicological studies,but also diagnosis and treatment of diseases.

RESUMO

This paper aims to describe the hematological and biochemical values of wild hybrid marmoset (Callithrix penicillata and C. geoffroyi) found in a forest zone of Southeastern Brazil. The marmosets were anaesthetized using ketamine and xylazine hydrochloride. Blood samples (0.5-1mL) were collected through the venipuncture of the femoral vein. Hematological and biochemical analyses were performed using automated counters and biochemical kits. The comparison for sex (adult males vs. adult females) and age class (juvenile vs. adult) physiological data and weight were analyzed through Student's t-test for independent samples. Significant differences between sex were observed in erythrocytes (P<0.01) and hemoglobin (P<0.05). The present study provides essential baseline information on the normal blood values of wild hybrid marmosets, the data of which are not readily accessible from the existing body of scientific literature on nonhuman primates.


Este artigo objetiva descrever os valores hematológicos e bioquímicos de saguis híbridos selvagens (Callithrix penicillata e C. geoffroyi) encontrados em uma zona florestal do Sudeste do Brasil. Os saguis foram anestesiados usando cetamina e hidrocloridrato de xilazina. As amostras de sangue (0,5-1mL) foram coletadas por punção da veia femoral. As análises hematológicas e bioquímicas foram realizadas por meio de contadores automáticos e kits bioquímicos. A comparação dos dados fisiológicos e pesos para o gênero (machos vs. fêmeas) e a classe de idade (juvenil vs. adulto) foram analisados através do teste t de Student para amostras independentes. Observaram-se diferenças significativas de gênero para eritrócitos (P<0,01) e hemoglobina (P<0,05). O presente estudo fornece informação básica essencial sobre os valores hematológicos normais de saguis híbridos selvagens, dados que não são prontamente disponíveis na literatura científica atual sobre primatas não humanos.

RESUMO

Tobacco use among youth is a major public health problem around the world. It kills millions of people worldwide, causes immense suffering, and also has enormous economic and social cost. A study was conducted to find out the effect of tobacco use on serum vitamin B12 and folic acid levels and related hematological indices and to find the correlation between duration of tobacco use, socioeconomic and education status with serum vitamin B12 and folic acid levels. It was seen that levels of vitamin B12, folic acid were significantly lower in tobacco users. Further, this level was lowest in subjects who consumed both chewable and smoked tobacco and lower in smokers in comparison to chewers.

RESUMO

<p><b>OBJECTIVE</b>To explore the antispermatogenic and testicular antisteroidogenic activities of Feronia limonia fruit pulp southern India.</p><p><b>METHODS</b>Fourty Wistar male albino rats (Rattus norvegicus) were equally divided into four groups. Experimental groups were administered with the ethanolic extract of Feronia limonia (F. limoni) fruit pulp at doses of 250 and 500 mg/kg body weight once daily for 55 days. All treated rats had corresponding recovery groups. At the end of each treatment periods, various spermatological indices, tissue biochemicals and testicular enzymes levels were analysed. Blood profiles were also estimated.</p><p><b>RESULTS</b>Compared with the control, the F. limonia fruit pulp at both dose levels did not decrease body weight, which were associated with decline in epididymal sperm count, motility, viability and increased percent of abnormal sperm. Further, F. limonia fruit pulp at 500 mg/kg body weight markedly reduced the epididymal and testicular protein content by 24.58% and 29.86%, respectively, as well as the glucose-6-phosphate dehydrogenase and Δ(5)-3β-hydroxy steroid dehydrogenase) levels by 42.82% and 38.08%, respectively, while a significant elevation was observed in testicular cholesterol and ascorbic acid content. A gradual recovery of all parameters was observed after 55 days of treatment withdrawal. No significant alterations in haematological indices were observed.</p><p><b>CONCLUSIONS</b>The present findings indicate that F. limonia fruit pulp may have reversible antispermatogenic and antisteroidogenic properties, and could partially support the traditional use as male contraceptive.</p>

RESUMO

This study was done to evaluate the health and nutritional status of female college students in Seoul. The subjects were 63 healthy college students aged 20 to 29 years. Their body composition, dietary intakes, clinical blood indices were investigated. Their body composition was determined by means of a multifreqency bioelectrical impedance analysis. Their dietary intake was determined using 3-day record method and their nutrient intake was analyzed by Computer Aided Nutritional analysis program for professional (CAN-pro). Their hemoglobin, hematocrit, red blood cell (RBC), white blood cell (WBC) and mean corpuscular volume (MCV) were determined by semi-automated microcell counter (F-520). Their plasma total cholesterol, TG, and HDL-cholesterol levels were measured using test kits. All data were statistically analyzed by SAS PC package program. Their average consumption of calcium, iron vitamin A, vitamin B2 and niacin were 63.3%, 65.0%, 85.2%, 89.2% and 95.2% of RDA, respectively. The overall mean values of the hematological indices in the female college students were within the normal range. However anemic subjects with hemoglobin ( 200 mg/dl) and LDL-cholesterol (> 130 mg/dl) were about 41% and 30.4%, respectively. The data showed a significantly positive correlation between either body fat (%) or BMI and TG. However, there was a significantly negative correlation between either body fat (%) or BMI and HDL-cholesterol. These overall results suggest that it is necessary for college women to be educated regarding consuming more iron and vitamin C and less fat, in order to prevent iron deficiency anemia and/or cardiovascular diseases in later life.

RESUMO

This study was due to investigate the dietary intakes, serum lipids and other hematological indices in female adolescent smokers. The subjects were 85 smokers, whose average pack-year(smoking years on the basis of one pack of cigarettes per day) was 1.26 and 87 nonsmokers who were female high school students in Seoul. An anthropometric measreument was performed and % body fat was also analyzed by the Bioelectrical Impedance Fatness Analyzer(GIF-891). Dietary intakes and food habits were examined through questionnaires and nutrient intakes were analyzed by the Computer Aided. Nutritional analysis program for professional(CAN-pro). Serum TG, HDL-cholesterol and total-cholesterol levels were measured with test kits. Serum glucose, albumin, GOT and GPT were measured by automated dry chemistry system, SPOTCHEM 4410. Hemoglobin, hematocrit, RBC, WBC and MCV were determined by Semi Automated Microcell Counter(F-520). All data were statistically analyzed by SAS PC package program. There was no significant difference in the anthropometric measurements between smokers and nonsmokers. The caloric intake in adolescent smokers tended to be higher than that of nonsmokers but the difference was not statistically significant. In addition, there was no significant difference between smokers and nonsmokers in biochemical indices. Analysis of serum lipids showed that the serum levels of total-cholesterol and LDL-cholesterol of nonsmokers were unexpectedly significantly higher(p<0.05) than those of smokers. Overall results indicate that smoking itself with short pack-year in healthy female adolescent did not seem to influence apparent health and nutritional status.
