Our objective was to determine age-specific rubella susceptibility among Egyptian females. This was a cross-sectional survey in eight randomly selected communities, with the largest number of reported rubella cases in the 2007 Rubella surveillance. A sample of 5672 females between the ages of 6 and 45 years were interviewed. Of those 602 blood samples were obtained and tested for rubella IgG. The proportion of seronegative females was 9.7%. The highest proportion of susceptible females was in the ages between 6 and 25 years and the highest risk of susceptibility was among unmarried females [odds ratio (OR)=7.2]. The knowledge of interviewed females about rubella, the vaccine and the effect rubella infection on pregnancy and on the fetus was very limited. In conclusion more vaccination coverage is needed, with simultaneous increase of public awareness to minimize the susceptible female population.

Shehata, H., N. Shalaby, M. El-Tamawy, and S. Jaafary, "rTMS for On-Freezers with Advanced PD. A Long Term Follow Up Study (S40.001)", Neurology, vol. 86, issue 16 Supplement, April 5, 2016. AbstractWebsite

Objective: Evaluating the long term efficacy and safety of rTMS sessions in management of ‘on-freezing’ and unpredicted offs in advanced Parkinson’s disease (PD).Background:Freezing of gait (FOG) is an independent feature of Parkinson’s disease that is related to both motor and cognitive deficits. Treatment of off-FOG is relatively straightforward, but ‘on-freezing’ is a difficult-to-treat scenario and it needs a multidisciplinary team approach.Design/Methods:A randomized, double-blind, placebo-controlled study included 43 patients with advanced PD who received 12 sessions of rTMS over 4 weeks (real or sham) every 3 months for a period of 9 months. rTMS (20 trains of 50 stimuli each, at 5 Hz) was delivered over the leg motor area contralaterally to the more affected side followed by a specific rehabilitation program (60 minutes). Treatments were synchronized with “on-time” to facilitate training sessions. All patients had their daily diary to record ‘on-times’, ‘offs’, ‘falls’, and ‘freezing episodes’. Primary efficacy variables were FOG Q (SF), unpredicted offs and UPDRS (motor section), secondary outcomes were on-time and gait variables (cadence, falls number, stride length and turn time). All patients signed a written consent.Results: Freezing episodes significantly decreased (p<0.05) and FOG Q (SF) significantly improved (p<0.001) in the active arm. Attacks of unpredicted offs also decreased significantly (p 0.03), whereas, the motor section of UPDRS improved, yet this was statistically non-significant. Number of falls reduced significantly (p<0.001) with improvement of turn time (p 0.04). Other gait variables were not affected. Long-term effects: the effects were maintained over the study period, the doses of dopaminergic drugs were individualized and modified according to the disease progression in both groups. No adverse events were recorded apart from mild transient headaches.Conclusions:rTMS has a positive effect in on-freezers with advanced PD with subsequent decrease of number of falls.Disclosure: Dr. Shehata has nothing to disclose.

The coronavirus disease 2019 (COVID-19) pandemic is a global health care emergency. Although reverse-transcription polymerase chain reaction testing is the reference standard method to identify patients with COVID-19 infection, chest radiography and CT play a vital role in the detection and management of these patients. Prediction models for COVID-19 imaging are rapidly being developed to support medical decision making. However, inadequate availability of a diverse annotated data set has limited the performance and generalizability of existing models. To address this unmet need, the RSNA and Society of Thoracic Radiology collaborated to develop the RSNA International COVID-19 Open Radiology Database (RICORD). This database is the first multi-institutional, multinational, expert-annotated COVID-19 imaging data set. It is made freely available to the machine learning community as a research and educational resource for COVID-19 chest imaging. Pixel-level volumetric segmentation with clinical annotations was performed by thoracic radiology subspecialists for all COVID-19-positive thoracic CT scans. The labeling schema was coordinated with other international consensus panels and COVID-19 data annotation efforts, the European Society of Medical Imaging Informatics, the American College of Radiology, and the American Association of Physicists in Medicine. Study-level COVID-19 classification labels for chest radiographs were annotated by three radiologists, with majority vote adjudication by board-certified radiologists. RICORD consists of 240 thoracic CT scans and 1000 chest radiographs contributed from four international sites. It is anticipated that RICORD will ideally lead to prediction models that can demonstrate sustained performance across populations and health care systems.

Hepatocellular carcinoma (HCC) is a universal health problem that is particularly alarming in Egypt. The major risk factor for HCC is hepatitis C virus (HCV) infection which is a main burden in Egypt. The epithelial cell adhesion molecule (EpCAM) is a stem cell marker involved in the tumorigenesis and progression of many malignancies, including HCC. We investigated the association of -935 C/G single nucleotide polymorphism in EpCAM promoter region (rs62139665) with HCC risk, EpCAM expression and overall survival in Egyptians. A total of 266 patients (128 HCV and 138 HCC cases) and 117 age- and sex-matched controls participated in this study. Genotyping, performed using allelic discrimination and confirmed by sequencing, revealed a significant association between EpCAM rs62139665 and HCC susceptibility, with higher GG genotype and G allele distribution in HCC patients than in non-HCC subjects. Such association was not detected in HCV patients compared to controls. EpCAM gene expression levels, determined in blood by RT-qPCR, and its serum protein expression levels, determined by ELISA, were significantly higher in GG relative to GC+CC genotype carriers in HCV and HCC patients in a recessive model. ROC analysis of EpCAM protein levels revealed significant discriminatory power between HCC patients and non-HCC subjects, with improved diagnostic accuracy when combining α-fetoprotein and EpCAM compared to that of α-fetoprotein alone. Altogether, EpCAM rs62139665 polymorphism is significantly associated with HCC and with EpCAM gene and protein expression levels in the Egyptian population. Moreover, serum EpCAM levels may hold promise for HCC diagnosis and for improving the diagnostic accuracy of α-fetoprotein.

Motawi, T. M. K., N. A. H. Sadik, D. Sabry, N. N. Shahin, and S. A. Fahim, "rs2267531, a promoter SNP within glypican-3 gene in the X chromosome, is associated with hepatocellular carcinoma in Egyptians.", Scientific reports, vol. 9, issue 1, pp. 6868, 2019. Abstract

Hepatocellular carcinoma (HCC) is a major health concern in Egypt owing to the high prevalence of hepatitis C virus (HCV) infection. HCC incidence is characterized by obvious male predominance, yet the molecular mechanisms behind this gender bias are still unidentified. Functional variations in X-linked genes have more impact on males than females. Glypican-3 (GPC3) gene, located in the Xq26 region, has lately emerged as being potentially implicated in hepatocellular carcinogenesis. The current study was designed to examine the association of -784 G/C single nucleotide polymorphism (SNP) in GPC3 promoter region (rs2267531) with HCC susceptibility in male and female Egyptian HCV patients. Our results revealed a significant association between GPC3 and HCC risk in both males and females, evidenced by higher C allele and CC/C genotype frequencies in HCC patients when compared to controls. However, no such association was found when comparing HCV patients to controls. Moreover, GPC3 gene and protein expression levels were significantly higher in CC/C than in GG/G genotype carriers in males and females. The CC/C genotype exhibited a significant shorter overall survival than GG/G genotype in HCC patients. In conclusion, GPC3 rs2267531 on the X chromosome is significantly associated with HCC, but not with HCV infection, in the Egyptian population.
