    Kurzfassung: BACKGROUND: Colorectal and gastric carcinomas are the most common and deadly gastrointestinal (GIT) malignancies. AIM: This study aimed to evaluate the expression of c-Met and p53 in gastric and colorectal carcinomas (CRCs) as well as colorectal adenomas using immunohistochemistry. MATERIALS AND METHODS: c-Met and p53 immunohistochemical expression was conducted on 66 cases of gastric adenocarcinomas and total of 60 colonic cases (36 CRCs and 24 colorectal adenomas). RESULTS: In this study, c-Met was positively expressed in 54.5% of gastric carcinomas and 50% of CRCs. In addition, p53 was positively expressed in 56.1% of gastric carcinomas and 72.2% of CRCs. Moreover, higher expression of both c-Met (p = 0.001) and p53 expression (p 〈 0.001) was reported in CRCs compared to colorectal adenomas. In the same context, c-Met and p53 expressions were positively correlated with intestinal type gastric adenocarcinoma (p 〈 0.001 and p = 0.03, respectively). Moreover, c-Met was correlated with non-mucinous adenocarcinomas (p = 0.008) and lower grades (p 〈 0.001) of gastric carcinomas. As regard survival analysis in gastric carcinomas, median overall survival (OS) was better in p53 positive patients (p = 0.05), patients with negative lymph node metastasis (p = 0.03), and patients with better response to neoadjuvant chemotherapy (p = 0.04). In contrast, c-Met did not exhibit significant correlation with OS (p 〉 0.05). Both c-Met and p53 did not reveal significant correlation with tumor stage and site in both CRCs and gastric carcinomas (p 〉 0.05). CONCLUSION: We concluded that c-Met and p53 are expressed in the most common GIT malignancies addressing them as potential biomarkers. In addition, c- Met and p53 may have a potential role in colorectal cancer development as they showed higher positivity in CRCs compared to adenomas.

    Kurzfassung: Hepatitis E virus (HEV) causes about 14 million infections with 300,000 deaths and 5,200 stillbirths worldwide annually. Extrahepatic manifestations are reported with HEV infections, such as renal, neurological, and hematological disorders. Recently, we reported that stool-derived HEV-1 replicates efficiently in human monocytes and macrophages in vitro . However, another study reports the presence of viral RNA but no evidence of replication in the PBMCs of acute hepatitis E (AHE) patients. Therefore, the replication of HEV in PBMCs during AHE infection is not completely understood. Methods PBMCs were isolated from AHE patients ( n = 17) enrolled in Assiut University Hospitals, Egypt. The viral load, positive (+) and negative (−) HEV RNA strands and viral protein were assessed. The gene expression profile of PBMCs from AHE patients was assessed. In addition, the level of cytokines was measured in the plasma of the patients. Results HEV RNA was detected in the PBMCs of AHE patients. The median HEV load in the PBMCs was 1.34 × 10 3 IU/ml. A negative HEV RNA strand and HEV open reading frame 2 protein were recorded in 4/17 (23.5%) of the PBMCs. Upregulation of inflammatory transcripts and increased plasma cytokines were recorded in the AHE patients compared with healthy individuals with significantly elevated transcripts and plasma cytokines in the AHE with detectable (+) and (−) RNA strands compared with the AHE with the detectable (+) RNA strand only. There was no significant difference in terms of age, sex, and liver function tests between AHE patients with detectable (+) and (−) RNA strands in the PBMCs and AHE patients with the (+) RNA strand only. Conclusion Our study shows evidence for in vivo HEV persistence and replication in the PBMCs of AHE patients. The replication of HEV in the PBMCs was associated with an enhanced immune response, which could affect the pathogenesis of HEV.

    Kurzfassung: Background: The aim of this study is to know the prevalence of blighted ovum among pregnant women in 1st trimester attending our hospital during their antenatal visits and to know the fate of blighted ovum either if there is spontaneous expulsion of the sac or need of medical induction or surgical evacuation.Methods: This observational study was conducted at Obstetrics and Genecology Department, Women Health Hospital and Sahel Selim Hospital, Egypt from November 2015 to February 2018. All patients recruited in this study attended the antenatal care clinics for antenatal follow-up during their first-trimester of pregnancies.Results: All cases of the study were less than 14 weeks. The mean gestational age was 8.93±1.01 (7.0-11.0) weeks. In patients less than 20 years old, (73%) there is a significant increase in surgical treatment (dilatation & curettage) after failure of medical treatment, patients more than 40 years old (50.7%) there is a significant increase in medical treatment after success taking misoprostol so there is no need to a surgical treatment by (dilatation & curettage) in the majority of cases.Conclusions: The prevalence of blighted ovum was 15.6%. Also, the prevalence of blighted ovum was statistically significant increased with increase maternal age and also, we noticed that there was a statistically significant association between early pregnancy failure and a history of previous early pregnancy loss.

    Kurzfassung: Background: The current study aims to assess the knowledge, attitude and practice of long acting reversible hormonal contraception (LARHC) among women in urban upper Egypt.Methods: A cross sectional study which included 902 married women, in the reproductive age, attending the outpatient clinics (Gynecology and family planning) of: 1-Assiut University Maternity Hospital, 2- Sohag University Hospital, and 3-Gehina General Hospital (MOH hospital) with current or previous use of any method of LARHC methods. A Questionnaire file was designed to assay knowledge attitude and practice of clients towards contraceptive methods. All data collected from clients reviewed separately to assess knowledge, attitude and practice of women towards contraceptive methods.Results: The most popular contraceptive method is COCs followed by IUD then DMPA. 99% of studied sample heard with good description about different types of LARHC. 54.9% of studied sample most popular/famous LARHC DMPA, most sources of information on LARHC were, Hospital, Relative/friends and health workers. 94.24% of the studied sample were in favor to use of LARHC, 94.2% of them agree to take a space between births, about 55.4% of them were health child and 61% comfortable lifestyle benefit from birth spacing, 33% of studied sample were maternal health, 68% of them were think/prefer to use implants, 64.5% of them didn’t pregnant while breastfeeding. 11% of sample women never used any contraception before and most reasons for not using contraception are fear of side effects, desire for more children, irregular sexual relationship, and husband opposition. Only 16.6 % of studied sample used LARHC before and most of them used DMPA, however 3 women who used DMPA get pregnant while using it.Conclusions: There is a good level of knowledge between upper Egypt women about LARHC methods.

    Kurzfassung: Arabic Sentiment analysis research field has been progressing in a slow pace compared to English and other languages. In addition to that most of the contributions are based on using supervised machine learning algorithms while comparing the performance of different classifiers with different selected stylistic and syntactic features. In this paper, we presented a novel framework for using the Concept-level sentiment analysis approach which classifies text based on their semantics rather than syntactic features. Moreover, we provided a lexicon dataset of around 69 k unique concepts that covers multi-domain reviews collected from the internet. We also tested the lexicon on a test sample from the dataset it was collected from and obtained an accuracy of 70%. The lexicon has been made publicly available for scientific purposes.

    Kurzfassung: Background: The aim of the present study is to determine role of hysteroscopy in women presented with primary or secondary infertility and in women presented with recurrent pregnancy loss.Methods: This cross-sectional study was conducted at Obstetrics and Genecology Department, Women Health Hospital Assiut University, Egypt from October 2016 to February 2018. Reproductive aged women who are suspected as having intrauterine pathology, such as submucosal myoma, endometrial polyps or other endometrial pathological findings based on the transvaginal ultrasound were enrolled. All patients were scheduled for office hysteroscopy as an outpatient. An informed consent was obtained prior to participation in the study.Results: Hysteroscopy was performed in 139 infertile women and 41 cases of repeated pregnancy loss. With regard to infertile patients; 67.6% of the patients had normal findings, 10.1% of the patients had intrauterine adhesion, 8.6% of the patients had intrauterine polyp. 5.8% of the patients had septate uterus and 3.6% of the patients had depressed fundus. With regard to patients with recurrent pregnancy loss; 51.2% of the patients had normal findings, 21.9% of the patients had partial septum, 9.8% of patients had intrauterine adhesions, 7.3% of patients had intrauterine polyp and 4.9% of the patients had submucous myoma.Conclusions: It was concluded that hysteroscopy should be considered as routine investigation in evaluation of women with primary and secondary infertility.
