Sustained Drug-Free Remission in Giant Cell Arteritis.

Objetive: To evaluate the frequency and timing of sustained drug-free remission (SDFR) in patients with giant cell arteritis (GCA) and to identify potential predictive factors of this outcome.

Methods: Retrospective review of all patients included in the large Spanish multicentre registry for GCA (ARTESER) with at least two years of follow-up. SDFR was defined as the absence of typical signs, symptoms, or other features of active GCA for ≥12 months after discontinuation of treatment.

Emergency room endotracheal intubation in children with bronchiolitis: A cohort study using a multicenter database.

Background And Aims: Bronchiolitis and asthma have a clinical overlap, and it has been shown that pediatric intensive care unit (PICU) patients with asthma undergoing endotracheal intubation in a community hospital emergency room (ER) have a shorter duration of mechanical ventilation (MV) and PICU length of stay (LOS) vs children undergoing intubation in a children's hospital. We aimed to determine if the setting of intubation (community vs children's hospital ER) is associated with the duration of MV and PICU LOS among children with bronchiolitis.

Methods: With IRB approval, data in the Virtual Pediatric Systems (VPS, LLC) database were queried for bronchiolitis patients <24 months of age admitted to one of 103 predominantly North American PICUs between 1/2009 and 1/2016 who had an endotracheal tube in place at PICU admission.

The expression profiling of serum miR-92a, miR-375, and miR-760 in colorectal cancer: An Egyptian study.

Dysregulation in microRNA expression is a common feature in colorectal cancer. Due to the inconsistent results regarding serum miR-92a expression pattern and the insufficient studies on serum miR-375 and miR-760, we aimed in this study to investigate their expression profile and diagnostic and prognostic power in Egyptian colorectal cancer patients. The expression profile of miR-92a, miR-375, and miR-760 was determined in the sera of 64 colorectal cancer patients using quantitative real-time reverse transcription polymerase chain reaction in comparison to 27 healthy control subjects.

Molecular assessment of vitamin D receptor polymorphism as a valid predictor to the response of interferon/ribavirin-based therapy in Egyptian patients with chronic hepatitis C.

Objective: The aim of this study was to find an association between serum concentration of vitamin D and vitamin D receptor (VDR) polymorphisms to achieve a sustained virological response (SVR).

Methods: We conducted a case-control study in which 250 participants were recruited and divided into three groups (100 chronic hepatitis C [CHC] patients who achieved SVR, 100 CHC patients who did not achieve SVR and 50 apparently healthy individuals as controls). Blood samples were collected to measure serum vitamin D concentration, and four VDR polymorphisms (FokI, ApaI, TaqI, and BsmI) were detected using polymerase chain reaction-restriction fragment length polymorphism.

Potential therapeutic utility of mesenchymal stem cells in inflammatory bowel disease in mice.

Mesenchymal stem cells (MSCs) were found to provide an effective therapeutic role in inflammatory diseases by modulating inflammatory responses and tissue regeneration by their differentiation ability. The present work sought to demonstrate the potential therapeutic use of MSCs in treating chronic inflammatory bowel disease (IBD) in mice. A new model to induce chronic IBD based on alternative administration periods of Dextran Sodium Sulfate (DSS) was established.

Serum human leukocyte antigen-G and soluble interleukin 2 receptor levels in acute lymphoblastic leukemic pediatric patients.

Aims And Background: Human leukocyte antigen-G and interleukin-2 receptor play pivotal roles in the proliferation of lymphocytes, and thus generation of immune responses. Their overexpression has been evidenced in different malignant hematopoietic diseases. This study aimed to validate serum soluble human leukocyte antigen-G (sHLA-G) and serum soluble interleukin-2 receptor (sIL-2R) as an additional tool for the diagnosis and follow up of acute lymphoblastic leukemia (ALL).

Role of chronic E. coli infection in the process of bladder cancer- an experimental study.

Background: Bladder cancer is a common malignancy in Egypt. A history of urinary tract infection can be considered as a risk factor for bladder cancer. Escherichia coli (E.
