Abdel Magid, A. M., M. M. Abbassi, E. E. M. Iskander, O. Mohamady, and S. F. Farid, "Randomized comparative efficacy and safety study of intermittent simvastatin versus fenofibrate in hemodialysis.", Journal of comparative effectiveness research, vol. 6, issue 5, pp. 413-424, 2017. Abstract

AIM: Compare the safety and efficacy of intermittent fenofibrate versus simvastatin in chronic hemodialysis patients.

PATIENTS & METHODS: Sixty patients received either fenofibrate 100 mg or simvastatin 20 mg after their dialysis session (parallel study). The safety and efficacy of drugs on lipid profile, oxidized low-density lipoprotein (Ox-LDL), glutathione peroxidase and C-reactive protein were compared before and after 16-week treatment.

RESULTS: After treatment, significant increase in glutathione peroxidase, significant decrease in total cholesterol, triglycerides, low density lipoprotein (LDL) and ox-LDL (p < 0.05) and no significant changes in C-reactive protein (p > 0.05) were observed in both groups. Both drugs were well tolerated with no serious side effects reported by the patients.

CONCLUSION: Both drugs have comparable efficacy and safety when used as intermittent low dose regimen in hemodialysis. Larger studies with longer follow-up periods are needed to confirm our new findings.

Abdel Moneim, M., D. H. Abdelaziz, Y. Ibrahim Nagy, A. A. Baki, A. S. Attia, and N. Sabry, "Rifaximin microbial resistance and its efficacy and safety as a secondary prophylaxis of hepatic encephalopathy in patients with HCV related cirrhosis.", International journal of clinical practice, pp. e14807, 2021. Abstract

BACKGROUND AND AIM: Rifaximin is an oral antibiotic with promising efficacy in the reduction of hepatic encephalopathy (HE) recurrence. Development of microbial resistance to rifaximin is not studied yet in HE. The study aim was to assess the microbial resistance, safety and efficacy of rifaximin as secondary prophylaxis of HE.

METHOD: In this open label parallel, prospective interventional study, 100 patients were randomly allocated either to receive 400 mg rifaximin 3 times/day plus 30-45 ml lactulose 3 times/day (intervention group) or to receive the standard of care only which is lactulose alone (control group) for 6 months. The primary outcome of the study was the difference between minimum inhibitory concentrations (MIC) of rifaximin among the two studied groups at the end of treatment. The secondary outcomes included the time to first episode of HE, time to first hospitalization, and patient's survival.

RESULTS: The MIC did not differ significantly after treatment exposure compared to baseline either between groups or within the same group. The time to new episode of HE was 18.84 ± 6.49 weeks (mean ± SD) in the intervention group and was significantly longer (p=0.002) than that in the control group 14 ± 7.52 weeks. Moreover, only 23 (46%) patients developed overt HE in the intervention group compared to 35 patients (70%) in the control group (p=0.005). Also, there was an observed 32% reduction in the risk of hospitalization in intervention group compared to control group.

CONCLUSION: Rifaximin succeeded to maintain remission from new episodes of HE in HCV cirrhotic patients with limited potential for development of microbial resistance over the study period.

Abdel Wahab, A. H. A., H. I. Abo-Zeid, M. I. El-Husseini, M. Ismail, and A. M. El-Khor, "Role of loss of heterozygosity on chromosomes 8 and 9 in the development and progression of cancer bladder.", Journal of the Egyptian National Cancer Institute, vol. 17, issue 4, pp. 260-9, 2005 Dec. Abstract

BACKGROUND: Loss of heterozygosity (LOH) in tumor samples is believed to be a marker for the absence of a functional tumor suppressor gene. Non-random chromosome deletion and LOH at specific chromosomal regions are identified in a number of common human cancers including carcinoma of the bladder, which is considered the most predominant cancer in Egypt due to the prevalence of schistosomiasis.

PURPOSE: The main objective of the present study is to clarify the role of chromosomes 8 and 9 in the establishment and/or progression of schistosomiasis-related bladder cancer through detection of LOH of 8 microsatellite markers on both chromosomes. It also aims to compare the LOH pattern of the tested markers between schistosomiasis- associated and non schistosomiasis-associated bladder cancer.

MATERIAL AND METHODS: To achieve this purpose, DNA was extracted from the tumor specimens and the corresponding peripheral blood samples of 42 primary bladder cancer patients (schistosomal and non schistosomal). Twenty nine of these were diagnosed as squamous cell type (SCC), 11 were transitional (TCC), and 2 were adenocarcinoma (with different stages and grades). LOH at chromosomes 8 and 9 was evaluated for 8 highly polymorphic microsatellite markers distributed at different regions of both chromosomes using the dinucleotide repeat-PCR technique.

RESULTS: The overall percentage of LOH in chromosome 8 was 74% in at least one marker. The highest incidence of LOH was recorded for D8S84 (41%) followed by 37% for D8S87, 29% for D8S85, and 25% for D8S88. Deletions at chromosome 8 were shown to be associated with high grade of the tumor and LOH at D8S85 was associated with metastatic lymph nodes. The overall percentage of LOH in chromosome 9 was 54% and its highest incidence was for D9S126 (36%), followed by 26%, 21%, 19% for D9S166, D9S128 and D9S180, respectively. Fifty nine percent (59%) of the cases with LOH at 9q were diagnosed as squamous cell type (SCC), whereas 9% only were transitional cell type (TCC). No significant association was recorded between the presence of schistosomiasis and LOH detected in all markers used in this study.

CONCLUSION: Our data indicate that more than one tumor suppressor gene on chromosomes 8 and 9 are involved in high grades of bladder carcinogenesis, one at 8p12 and another at 8q21.1 regions. Also, a region at 8q23-quarter may harbor tumor suppressor gene that involved in metastasis of bladder cancer. Our study also revealed that 9p21 (p16INK4) region is involved in both types of the tumor (SCC & TCC). PTCH located at 9q22.3, as well as the TSC gene at 9q34 are involved in squamous cell carcinoma rather than transitional carcinoma. Region 9q12-13 is considered to be a critical region of urothelial tumor suppressor genes. Finally, the present study shows no line of demarcation between schistosomiasis-associate and non schistosomiasis-associated bladder cancer in terms of LOH of the tested microsatellite markers on chromosome 8 and 9. This suggests that data obtained from schistosoma-associated bladder cancer can be extrapolated to bladder cancer induced by a schistosomiasis independent mechanism.

The influence of a frequency on the relative permittivity ε′r as well as the AC conductivity of metal alginate complexes (Ba2+, Sr2+, Pb2+, Cd2+ or Zn2+ ions) as a function of temperature has been investigated.The average values of the activation energy obtained from the experimental data indicate that the electrical properties of the complexes under investigation are similar to those of semiconducting materials. The values of relative permittivity ε′r increase with temperature until a maximum value designated by γ-relaxation is obtained. The appearance of β-relaxation as a small shoulder is discussed in terms of the movement of the side groups and the small units of the main chain which in turns allows the orientation of dipolar units in the applied electric field.

This study investigates the impact of risk management and disclosure on firm value. The study aims at investigating three relationships; the first is the relationship between risk management and firm value. The second is the relationship between corporate voluntary disclosure and systematic (market/beta) risk. The third is the relationship between voluntary disclosure and firm value. The study population consists of non-financial companies listed on the Egyptian Stock Exchange (EGX) at the year-end of 2012.
For testing the first relationship; the logistic model developed by Wang, Li, and, Z. (2010) is used, and Tobin’s Q ratio is used for calculating firm value. The logistic model developed by Hassan, Gianluigi, and Power (2011) is followed in measuring the second relationship. The Capital Asset Pricing Model (CAPM) Model is used for calculating Beta for systematic market risk, and the voluntary disclosure is measured using the disclosure index technique including 26 financial and non-financial items. The third relationship is tested by modifying Rahmat and Hoffman (2011) model. The results indicate that a positive relationship exists between risk management and firm value, a negative relationship exists between voluntary disclosure and the market risk exposure, and a positive relationship exists between voluntary disclosure and firm value.
