Objective: To assess the efficacy of intravenous tranexamic acid and ethamsylate in reducing blood loss during and after elective lower segment cesarean delivery in patients at high risk for postpartum hemorrhage. Methods: A double-blind, randomized placebo-controlled study was undertaken of women undergoing elective lower-segment cesarean delivery of a full-term pregnancy at high risk for postpartum hemorrhage at Ain Sham University Maternity Hospital in Cairo, Egypt, between January 2019 and October 2019. Patients were randomly assigned (1:1) using computer-generated random numbers to receive either 1 g tranexamic acid and 1 gm ethamsylate or 5% glucose (placebo) just after delivery of the fetus. Prophylactic oxytocin was administered to all women. Preoperative and postoperative complete blood count, hematocrit values, and maternal weight were used to calculate the estimated blood loss (EBL) during the cesarean, which was the primary outcome. Results: Analyses included 32 women in each group. Our results showed that tranexamic acid and ethamsylate significantly reduced bleeding during and after cesarean delivery. The study group's total blood loss (149.22 ± 54.74 ml) was significantly less than the control group (353.75 ± 115.56 ml) (p < 0.001). In our study, postoperative hemoglobin and hematocrit were significantly higher in the study group than the control group (p < 0.001); Reduction in hemoglobin and hematocrit were significantly less in the study group than the control group (p < 0.001). Conclusion: The use of tranexamic acid and ethamsylate during cesarean delivery can significantly reduce blood loss during and after cesarean delivery.

Use of date and olive stones as a raw material available in large quantity in Egypt for producing a low cost activated carbon and characterization in this work. The preparation method entails the impregnation of the dried and crushed stones with activated agent ZnCl2 followed by carbonization at high temperature. The quality of the activated carbon prepared was identified by Physical and chemical characterization. The both prepared activated carbon has very large surface area as well as highly developed micro porosity, with good capacity for iodine and methylene blue removal. The objective of this research was to investigate the potential of the two prepared and commercial available activated carbon as sorbent for removing viruses from water and to delineate the sorption mechanism. Powdered activated carbon successfully removed it under the same condition than granular form with priority for our prepared from stones. Three factors contributed to virus removal: a smaller electrophoretic repulsive force between the virus and the activated carbon particles, a small proportion of pores 1.6 and 3.7 nm in diameter, and a greater hydrophobicity of the virus surface.

Background: Preterm birth is a leading cause of perinatal death and disability and is an important public health problem globally. There is more work to be done regarding steroids effect, especially with the variations among demography and pathological conditions affecting mothers. The aim of this study was to investigate the effect of dexamethasone on healthy fetuses, observing the effects on MCA and UA Doppler velocity waveforms and cardiotocography, correlating them with fetal movement.Methods: This prospective cross-sectional study was conducted in Ain Shams University Maternity Hospital, starting from April 2020 till December 2020. One hundred and ten women was recruited for the study. All women undergo elective cesarean section before 39 weeks of gestation. UA and MCA Doppler values were taken; nonstress test was recorded and fetal movements were counted after a single course of dexamethasone.Results: Our results included decrease in MCA PI, decrease in foetal movement count on the second day of dexamethasone injection, increase of short-term variability and direct correlation between the MCA RI and UA PI with the fetal movements decrease on the 5th day of dexamethasone injection.Conclusions: There are definitely cardiovascular changes that occur after dexamethasone administration, presented by increase in MCA blood flow and increase in FHR short term variability.
