Toxic cement dust causes inflammatory damage to different body organs. White blood cells (WBCs) are considered cellular markers of ongoing tissue inflammation.Aim of the Study: Determining the influence of occupational cement dust exposure on WBCs with its differentials (inflammatory markers) in workers from the cement manufacturing plant.Methodology: Ninety-two seemingly healthy male subjects (46 workers of cement plant and 46 control subjects, who do not contact cement dust, residing in Dhaka) aged between 20 and 50 years participated in this cross-sectional study. This study took place in Dhaka Medical College, Bangladesh, between the years of 2017 and 2018. An automated hematoanalyser was used to assess both the total and differential count of WBC. Data were analyzed with multivariate regression analysis, independent samples t-test, and correlation test.Results: The total WBC count, differential count of lymphocyte, and eosinophil were significantly (p< 0.05) higher in cement dust-exposed recruits than in the control group. Additionally, multivariate regression analysis revealed that duration of cement dust exposure showed a significant association with total WBC count [odds ratio (OR)=4.42,95%, confidence level (CI) 1.56,12.47, p 0.005]. Furthermore, univariate analysis revealed that the control group (not exposed to cement dust) was less likely to have the total WBC count alteration (OR = 0.122, 95% CI =0.047 to 0.311) than the cement dust-exposed group. The total WBC count showed a significant positive correlation with exposure duration to this toxic dust.Conclusion: Cement dust exposure causes harmful inflammatory responses, as evidenced by increased total and differential WBC count. The period of contact with this toxic dust has an impact on WBC count.Keywords: cement dust, occupational health, inflammatory response, hazard, workers, exposure, WBC count, biomarkers, Bangladesh, pollution, hematological system, early detection

Abstract

Background: Iron deficiency anemia (IDA) is the most common nutritional disorder in pregnancy in developing countries. Different iron preparations are supplemented to treat IDA in pregnancy, which can lead to different side effects like nausea, vomiting, decreased appetite, constipation or diarrohea, hyperacidity. Emblica officinalis is a well known traditional fruit to reduce these side effects. Aim: To determine the side effects of iron supplementation and beneficial role of amloki in pregnancy to reduce these side effects.Methods and materials: This interventional study was done in the Department of Physiology, Dhaka Medical College, Dhaka from July 2016 to June 2017. From the Outpatient Department of Obstetrics and Gynaecology, Dhaka Medical College and Hospital, 46 pregnant women were selected purposively on the basis of inclusion and exclusion criteria. Anaemic pregnant women supplemented with oral iron and amloki were considered as study groups (Group A) and pregnant women supplemented with only iron for 45 days were considered as control group (Group B). A previously formed structured questionnaire was used to evaluate the subjective complaints. Chi-square test was performed to compare between the groups. The test of significance was calculated & p value < 0.05 was accepted as level of significance. Results: Significant improvement in different subjective parameters nausea, vomiting, decreased appetite, constipation, hyperacidity (p
