Survival of patients with non-viral hepatocellular carcinoma treated with trans-arterial chemoembolization: A multicenter cohort study.

Background And Study Aims: Few studies have considered patients treated with trans-arterial chemoembolization (TACE) for non-viral-induced hepatocellular carcinoma (HCC), with some reporting that those patients may have larger tumors, emphasizing the need for determination of the factors affecting survival in such patients. This work aims to study the characteristics and survival of patients with non-viral related HCC treated with TACE.

Patients And Methods: This is a multicenter observational study.

Characteristics and survival of patients with viral versus nonviral associated hepatocellular carcinoma: a multicenter cohort study.

Background: Viral hepatitis B and C are the leading causes of hepatocellular carcinoma (HCC). With obesity, metabolic-related disorders are increasingly associated with a higher incidence of nonviral HCC. This study aimed to investigate the characteristics, tumor features, treatment outcomes, and survival of patients with viral versus nonviral HCC.

An efficient neural network LEACH protocol to extended lifetime of wireless sensor networks.

This paper presents NN_ILEACH, a novel neural network-based routing protocol designed to enhance the energy efficiency and longevity of Wireless Sensor Networks (WSNs). By integrating the Energy Hole Removing Mechanism (EHORM) with a sophisticated neural network for cluster head selection, NN_ILEACH effectively addresses the energy depletion challenges associated with traditional protocols like LEACH and ILEACH. Our extensive simulations demonstrate that NN_ILEACH significantly outperforms these classical protocols.

Prospective Comparison of Hepatocellular Carcinoma Behavior and Survival of Patients who Did or Did not Receive HCV Direct-Acting Antivirals.

Background & Aims: The safety and efficacy of hepatitis C (HCV) direct-acting antivirals (DAAs) have been established in several real-world trials; however, some reports have claimed an association between DAAs and hepatocellular carcinoma (HCC) occurrence or aggressive behavior. We aimed to prospectively examine differences in de-novo HCC tumor behavior and overall survival (OS) in DAAs-treated versus HCV-untreated patients as measured by BCLC progression during a two-year follow-up period.

Methods: This multicenter cohort study recruited 523 patients with de-novo HCV-related HCC.

The COVEG score to predict severity and mortality among hospitalized patients with COVID-19.

Introduction: COVID-19 severity and mortality predictors could determine admission criteria and reduce mortality. We aimed to evaluate the clinical-laboratory features of hospitalized patients with COVID-19 to develop a novel score of severity and mortality.

Methodology: This retrospective cohort study was conducted using data from patients with COVID-19 who were admitted to five Egyptian university hospitals.

Sofosbuvir/ledipasvir in combination or nitazoxanide alone are safe and efficient treatments for COVID-19 infection: A randomized controlled trial for repurposing antivirals.

Background And Study Aims: Currently, there is no therapy approved for COVID-19. We evaluated the efficacy and safety of sofosbuvir/ledipasvir and nitazoxanide for the treatment of patients with COVID-19 infection.

Patients And Methods: A multicenter, open-label randomized controlled trial included one hundred and ninety patients with non-severe COVID-19 infection.

Chloride-binders and their effect on the physico-mechanical properties of sulfate-resisting cement (SRC) hardened pastes upon exposure to sea water attack.

In Egypt, the national strategic plan for population redistribution supports the establishment of new towns and urban settlements across the coastal zones to relieve the pressure on the packed Nile Valley and Delta and encourages internal migration to new urban coastal communities. Since reinforced concrete has a poor service record in these areas, this situation urged us to design a research program in which a new route has been followed for confronting the concomitant effect of sulfate and chloride attack. Therefore, sulfate-resisting cement (type V) has been used for preparing concrete.

Management of life-threatening acute respiratory syndrome and severe pneumonia secondary to COVID-19 in pregnancy: A case report and literature review.

Evidence-based treatment involving multidisciplinary decision making is warranted to treat COVID-19 in pregnancy. This case presents the management of a critically ill pregnant women infected with SARS-CoV-2.

Clinical features and laboratory characteristics of patients hospitalized with COVID-19: single centre report from Egypt.

Introduction: The recently discovered novel coronavirus disease (COVID-19) has emerged in Wuhan, China, since January 2020. Egypt reported a low incidence of infection when compared with other countries. The aim of the study was to assess the characterization of COVID-19 infection among the Egyptian population.

Double-balloon valvuloplasty of calcified bioprosthetic pulmonary valve twenty-three years after implantation.

Balloon valvuloplasty to dilate stenotic bioprosthetic valves is rarely used, but has been applied successfully to dilate bioprosthetic mitral, aortic, tricuspid and, to a lesser extent, pulmonary valves. The case is reported of a 45-year-old male patient with right-sided heart failure who underwent a successful dilatation of a stenotic, calcific bioprosthetic pulmonary valve using double-balloon valvuloplasty.

Giant left atrium associated with massive thrombus formation.

Giant left atrium is a condition characterized by huge enlargement of the left atrium with a diameter exceeding 65mm. It is most commonly associated with long standing rheumatic mitral valve disease. We present a 45-year-old female patient with rheumatic mitral stenosis associated with giant left atrium occupied by an 11 × 10 × 5 cm thrombus weighing 500 gms.

Percutaneous mitral valvotomy versus closed surgical commissurotomy. Up to 15 years of follow-up of a prospective randomized study.

Background: Immediate and intermediate term results of percutaneous mitral valvotomy (PMV) are comparable to closed surgical commissurotomy (CSC). We aimed at exploring this relation in the long term.

Methods: Previously, we randomized 40 consecutive patients with moderate to severe mitral stenosis [defined as mitral valve area (MVA) less than 1.
