Hepatitis B and C: prevalence and risk factors associated with seropositivity among children in Karachi, Pakistan

Background Infections with hepatitis B virus (HBV) and hepatitis C virus (HCV) can lead to chronic liver disease and hepato-cellular carcinoma (HCC). This cross-sectional study estimated the prevalence and identified risk factors associated with Hepatitis B surface antigen (HBsAg) and HCV antibody (anti-HCV) sero-positivity among children 1 to 15 years of age. Methods The study targeted the low to middle socioeconomic population that comprises 80% to 85% of the population. Consent was obtained from parents of the eligible children before administering questionnaire and collected a blood sample for anti-HCV and HBsAg serology. Results 3533 children were screened for HBsAg and anti-HCV. 1826 (52 %) were males. 65 (1.8 %) were positive for HBsAg, male to female ratio 38:27; mean age 10 ± 4 years. 55 (1.6 %) were positive for anti-HCV with a mean age 9 ± 4 years. 3 (0.11%) boys were positive for both HBsAg and anti-HCV. The overall infection rate was 3.3 % in the studied population. Hepatitis BsAg was more prevalent in subjects who received therapeutic injections 45 (69.2%) positive [Odd Ratio OR = 2.2; 95% Confidence interval CI: 1.3–3.6] inspite of using new needle and syringe 44 (67.7%) positive [OR = 2.2; 95% CI: 1.3–3.7] and vaccination in the government healthcare facilities 46 (70.7 %) positive with [OR = 3.0; 95% CI: 1.4–6.4].

Process Optimization Of EDM Cutting Process On Tool Steel Using Zinc Coated Electrode

In WEDM machining process, surface finish quality depends on intensity and duration of spark plasma. Electrode wire diameter has significant effect on the spark intensity and yet the studies on this matter still less. Therefore, the main objectives of this studies are to compare the different diameters of zinc coated and uncoated brass electrode on H13 tool steel surface roughness. The experiments were conducted on Sodick VZ300L WEDM and work piece material of tool steel AISI H13 block. Electrode of zinc coated brass with diameters of 0.1 mm, 0.2 mm, 0.25 mm and uncoated brass 0.2 mm were used. The surface roughness of cutting was measured using the SUR-FTEST SJ-410 Mitutoyo, surface roughness tester. The results suggest that better surface roughness quality can be achieved through smaller electrode wire diameter. The zinc coated improves flushing ability and sparks intensity resulting in better surface finish of H13 tool steel. New alloys and coating materials shall be experimented to optimized the process further

Islamic Legal Hybridity in the Mappatoi System: Sharia Economic Adaptation among Minority Muslim Communities in Plural Society
