Effect of Iron Deficiency Anemia on Intellectual Performance of Primary School Children in Islamabad, Pakistan

Purpose: To assess the differences, if any, in the intellectual performance scores of children who have iron deficiency anemia and those who are neither anemic nor iron-deficient in New Kashmir Model School, Islamabad, Pakistan.Methods: A total of 108 primary New Kashmir Model School children of Islamabad, Pakistan between the ages of 7 to 9 years were included in the study. They were divided into two groups based on Iron deficiency anemia and Non-anemia children’s. A brief clinical history and physical examination was performed. All the 5 mandatory subjects of WISC-R were administered to the children of both groups. Electronic cell counter was used for the evaluation of hemoglobin, packed cell volume (PVC), mean cell volume (MCV), Mean cell hemoglobin (MCH) while serum parameters were determined after first separating serum from blood. Giemsa stain was used to evaluate red cell morphology.Results: Seventy six of these children had iron deficiency anemia based on their hemoglobin, packed cell volume, serum iron, total iron binding capacity and serum ferritin levels. The remaining 32 children were neither anemic nor iron-deficient based on their profiles. Intellectual performance scores which comprised of central nervous system (CNS) impact, as well as hemoglobin, packed cell volume, serum iron, total iron binding capacity and serum ferritin levels and also clinical parameters for the iron deficiency anemia group, were significantly lower than those of the non-anemia group.Conclusion: Iron deficiency anemia appears to be associated with lower intellectual performance scores in school children. These results support previous findings that iron depletion leads to psychological and developmental effects in children.Keywords: Intellectual performance, Anemia, Children, Psychological and developmental effect

Neonatal mortality in Sudan: analysis of the Sudan household survey, 2010

BACKGROUND: Sudan is classified as having insufficient progress in achieving the Millennium Development Goal (MDG-4), where the levels of child and infant mortality are among the highest in the region and the world. This study investigated factors associated with neonatal mortality in Sudan. Neonatal death is defined as death within the first 28 days of life. METHODS: This study analysed data from the Sudan Household Health Survey 2nd round, which was carried out in 2010. Total of 6,198 live-born infants delivered within the two years preceding the survey were included as the study population. Multivariate logistic regression was used to model neonatal mortality as a function of maternal health parameters, socioeconomic indicators and the sex of the child. RESULTS: There were 189 neonatal deaths out of 6,198 live births (3.0%). In the multiple logistic regression, the factors associated with neonatal mortality were advanced maternal age (≥ 40 years; OR = 2.4; 95% CI: 1.21, 4.78, p = 0.012), poor household wealth index (OR = 1.6; 95% CI: 1.18, 2.47, p = 0.005), male child (OR = 1.8; 95% CI: 1.31, 2.42, p < 0.001), delivery of baby by Caesarean section (OR = 1.6; 95% CI: 1.78, 2.42, p = 0.013) and delivery complications (OR = 1.4; 95% CI: 1.18, 2.15, p = 0.002). CONCLUSION: Public health interventions which target neonatal mortality reduction should adopt a risk-factor-based approach to detect pregnancy complications early and once identified, the health system should be strengthened so that these complications can be dealt with adequately

Screening of Guava genotypes to natural infestation of fruit flies (Diptera:Tephritidae) in River Nile, Sennar and North Kordofan States, Sudan

The infesting species and their infestation indices of fruit flies were determined for guava genotypes (Psidium guajava L.),grown in River Nile, Sennar and North Kordofan States during the period from June to August 2010 .Twenty genotypes were selected from each state to be evaluated ,where ten mature fruits from each genotypes were harvested randomly from insecticide unsprayed trees. Fruits were brought to the laboratory and placed in individual plastic vials containing sand at the bottom to obtain the pupae. Infestation indices were estimated by means of total number of pupae/fruit. Pupal viability was then calculated based on the percentage of pupae resulted in fly emergence. Data was analyzed using analysis of variance and Duncan multiple range test for mean separations. Results showed that Guava fruits were infested by four fruit fly species Ceratitis cosyra, C.quinaira, C capitata and Bactrocera dorsalis constitute (82.2), (0.8), (16.7), (0.3% ) and 28.35 ,0.01 ,10.1 and 61.56% in River Nile and Sennar States respectively. While in North Kordofan State guava fruits were infested by C.cosyra, C.capitat and B.dorsalis 98.4,0.4 and 1.2% respectively. All the evaluated genotypes in River Nile and Sennar States were infested by the fruit fly with varying degrees only two genotypes 15 red flesh fruit and 19 white flesh fruit in Kordofan state were found free from fruit fly infestation. Infestation was much higher in Sennar and River Nile states (32 and 29 pupae/fruit) respectively compared to North Kordofan (1.6 pupae/fruit).The higher infestation rate occurred in ripe guava fruits (33) compared to 18 and 6 pupae/fruit in mature green and immature green fruit respectively

Effect of Grazing of Dairy Cows on Bt Cotton Crop Residues on Milk and Cheese Chemical Composition and Sensory Properties

This experiment was conducted in two localities in Gezira state, Sudan. The objective of the experiment was to investigate; the effect of grazing cattle on genetically modified cotton crop residues (designated as Bt-CCR) on milk and cheese chemical composition and sensory characteristics. The results revealed that, there was significant differences (P&lt;0.01) between milk produced from grazing on Bt and on non- Bt CCR. With exception of fat, all other milk components were significantly (P&lt;0.01) higher in milk produced from grazing on Bt CCR. Also the same trend was found in cheese produced from Bt milk. In sensory evaluation of milk, consistency, flavor, taste and overall assessment were significantly better in non Bt milk. While there was no significant difference in sensory characteristics between the cheese produced from Bt and non-Bt milk. It was concluded that, grazing on Bt CCR significantly affect milk and cheese chemical composition but only sensory characteristics in milk. However, more investigation to elucidate these reasons is needed
