RESUMO

OBJECTIVE: Nutritional deficiencies are very significant to the overall health of humans at all ages and for both genders, yet in infants, children and women of childbearing age these deficiencies can seriously affect growth and development. The present work is aimed to assess homocysteine and vitamin B12 status in females with iron deficiency anemia from the Gaza Strip. METHODS: Venous blood samples were randomly collected from 240 female university students (18-22 years old) and parameters of the complete blood count, serum ferritin, homocysteine and vitamin B12 were measured. Statistical analysis included the t-test and analysis of variance (ANOVA) using the IBM SPSS software (version 18). Statistical significance was set for p-values <0.05. RESULTS: The results revealed that 20.4% of the students have iron deficiency anemia. The mean serum vitamin B12 level in females with iron deficiency anemia (212.9±62.8pg/mL) was significantly lower than in normal controls (286.9±57.1pg/mL) and subjects with microcytic anemia and normal ferritin (256.7±71.1pg/mL). Significantly higher serum homocysteine levels were reported in the iron deficiency anemia group (27.0±4.6µmol/L) compared to normal controls (15.5±2.9µmol/L) and in subjects with microcytic anemia and normal ferritin (18.1±2.7µmol/L). Statistically significant negative correlations were reported for serum homocysteine with serum ferritin, vitamin B12, hemoglobin, and hematocrit levels. CONCLUSION: Important associations were found between serum homocysteine and markers of iron deficiency. Monitoring homocysteine levels might be essential to understand the development of different clinical conditions including anemia. It seems necessary to conduct prospective trials to determine whether treating anemia ameliorates homocysteine levels.

RESUMO

INTRODUCTION: Storing blood as dried spots on filter paper is a trustworthy approach used in genetic screening issues which justifies the necessity for a reliable DNA extraction method. The present work aims to investigate the effectiveness of superparamagnetic-bead based method in extracting DNA from dried blood spots (DBS). MATERIALS AND METHODS: Sixteen venous blood samples collected in K3-EDTA tubes (400µl of whole blood) were used for the spotting (4 circles each 100µl) on Ahlstrom 226 grad filter papers, for extraction and comparison. To ensure effectiveness, the extracted DNA was checked for quantity using the Quant-iT™ dsDNA Broad-Range Assay Kit and for quality by polymerase chain reaction (PCR) amplification of 344 bp segment of the HBB gene. Hybridization assays based on the dynamic allele specific hybridization (DASH) technique for two hemoglobin beta (HBB) mutations in genomic DNA extracted from DBS of ß-thalassemia patients were also performed to ensure the quality of extraction. RESULTS: The results revealed a compatible effectiveness of the superparamagnetic-bead based method in extracting DNA from DBS particularly when incubating the DBS with lysis buffers BL+BLM overnight. A mean concentration of 21ng/ µl was obtained with lysis buffers BL+BLM overnight incubation compared to 5.2 ng/µl for 2 h incubation with lysis buffers BL+BLM and 4.7 ng/µl when extraction performed using the lysis buffer BLM alone. Moreover, PCR amplification of 344 bp segment of the HBB showed a good quality of the extracted DNA. CONCLUSION: It was concluded that the superparamagnetic-bead based method is a reliable and effective method for DNA extraction from DBS and can be adopted for genetic diagnostic purposes.

RESUMO

BACKGROUND: iron deficiency anemia is the most common type of nutritional anemia; it has been recognized as an important health problem in Palestine. This study was conducted to estimate the prevalence and to identify possible risk factors of iron deficiency anemia among kindergarten children living in the marginalized areas of the Gaza Strip and to evaluate the effectiveness of supplementing oral iron formula in the anemic children. METHODS: the study included 735 (384 male and 351 female) kindergarten children. Data was collected by questionnaire interviews, anthropometric measurements, and complete blood count analysis. All iron deficient anemic children were treated using an oral iron formula (50 mg ferrous carbonate + 100 mg vitamin C /5 mL) and the complete blood count was reassessed after three months. A univariate analysis and a multiple logistic regression model were constructed; crude and adjusted odds ratios (OR), and 95% confidence intervals (95% CI) were calculated. RESULTS: the overall prevalence of iron deficiency anemia was 33.5% with no significant differences between boys and girls. Significantly different prevalences of iron deficiency anemia were reported between different governorates of the Gaza Strip. Governorate, low education level of the parents and smoking are significant risk factors for children developing anemia. Significantly lower complete blood count parameters, except for WBC, were reported in anemic children. The oral iron treatment significantly improved hemoglobin concentrations, and normalized the iron deficiency marker. CONCLUSIONS: iron deficiency anemia is a serious health problem among children living in the marginalized areas of the Gaza Strip, which justifies the necessity for national intervention programs to improve the health status for the less fortunate development areas.

RESUMO

The inability to procreate is frequently considered a personal tragedy and a hardship for couples, impacting on the entire family and even the local community. In Gaza strip, Palestine, there has been no study on etiological risk factors for subfertility. The present study aimed to identify risk factors associated with subfertility among women in Gaza, Palestine. One hundred and sixty-nine women in the study group and 115 women in the control group were included. Cases were selected randomly from those referred to the Al Basma Fertility Center, Gaza, Palestine. Data were collected through close-ended questionnaire, sonography, hormonal analysis and thrombophilia profile that included the methylenetetrahydrofolate reductase (MTHFR 677 C > T), factor V leiden (1691 G > A) and prothrombin (20210 G > A) genes. By using univariate analyses, the effects of different patient-related variables on the presence of subfertility were evaluated. A multiple logistic regression model was constructed, crude and adjusted odds ratios (OR) and 95% confidence intervals (95% CI) were calculated. The findings showed that 73.5 % (169/230) of the women referred to the Al Basma Center sought treatment for subfertility. Different etiological risk factors were associated with subfertility, the most frequent of which in descending order were: thrombophilic disorders, fallopian tube problems, sex hormone abnormalities and polycystic ovary syndrome with an adjusted OR of 21.42, 13.63, 11.69 and 10.29, respectively. In conclusion, several etiological risk factors are responsible for subfertility among women in Gaza. Comprehensive evaluation of infertile women should be considered in the course of treatment; otherwise, the duration of sterility may be extended.

RESUMO

BACKGROUND: The complete blood count is one of the most common routine tests. This study aimed to evaluate possible effects of the antioxidant taurine on the complete blood count of whole blood stored at room temperature and at 4ºC over seven days. METHODS: Venous blood samples of 25 healthy males were distributed into two sets of tubes with each set of four tubes containing 50 µL of solutions with zero, 2.5 g/L, 5 g/L, 10 g/L taurine. The tubes were kept at room temperature or at 4ºC. Complete blood counts were performed on seven successive days. The mean percentage changes [Δ = (mean value - mean baseline value) / mean baseline value x 100] were calculated and compared. RESULTS: Complete blood count parameters exhibited different patterns of behavior which were affected by the storage temperature, time and taurine concentration. Taurine at room temperature significantly enhanced the stability of: the platelet count over seven days (Δ7 at 2.5, 5 and 10 g/L taurine were 5.45, 6.11, and 5.80 x 10(9) cells/L, respectively); the red blood cell count over five days (Δ5 at 2.5, 5 and 10 g/L taurine were 1.59, 2.79, and 1.98 x 10(12) cells/L, respectively); mean corpuscular hemoglobin over five days (Δ5 at 2.5, 5 and 10 g/L taurine were -0.91,-1.52 and -0.84 fl respectively); and red cell distribution width over two days (Δ2 at 2.5, 5 and 10 g/L taurine were 0.90%, 1.30% and -0.1%, respectively). No additional stabilizing effects of taurine were reported for the mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, hematocrit and hemoglobin, while it negatively affected the white blood cell stability. CONCLUSION: Complete blood count parameters exhibited variable stability patterns in respect to temperature, time and taurine concentration.
