International alliance and AGREE-ment of 71 clinical practice guidelines on the management of critical care patients with COVID-19: a living systematic review.

Objective: We aimed to systematically identify and critically assess the clinical practice guidelines (CPGs) for the management of critically ill patients with COVID-19 with the AGREE II instrument.

Study Design And Setting: We searched Medline, CINAHL, EMBASE, CNKI, CBM, WanFang, and grey literature from November 2019 - November 2020. We did not apply language restrictions.

Quality assessment of evidence-based clinical practice guidelines for the management of pregnant women with sickle cell disease using the AGREE II instrument: a systematic review.

Background: The management of pregnant women with sickle cell disease (SCD) poses a major challenge for maternal healthcare services owing to the potential for complications associated with morbidity and mortality. Trustworthy evidence-based clinical practice guidelines (CPGs) have a major impact on the positive outcomes of appropriate healthcare. The objective of this study was to critically appraise the quality of recent CPGs for SCD in pregnant women.

The Risk and Prognosis of COVID-19 Infection in Cancer Patients: A Systematic Review and Meta-Analysis.

Numerous studies have been published regarding outcomes of cancer patients infected with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus causing the coronavirus disease 2019 (COVID-19) infection. However, most of these are single-center studies with a limited number of patients. To better assess the outcomes of this new infection in this subgroup of susceptible patients, we performed a systematic review and meta-analysis to evaluate the impact of COVID-19 infection on cancer patients.

Allogeneic hematopoietic stem cell transplantation in adolescent and adult patients with high-risk T cell acute lymphoblastic leukemia.

Allogeneic hematopoietic stem cell transplantation (allo-SCT) is often recommended for patients with T cell acute lymphoblastic leukemia (T-ALL) in second or later complete remission (≥CR2) and sometimes in high-risk (HR) patients in first complete remission (CR1). Between January 1995 and July 2009, 53 patients with HR T-ALL underwent allo-SCT at our institution. Median age was 18 years (range, 14-51).

Right heart thrombus-in-transit with pulmonary embolism in a patient with primary hypercoagulable state.

A 25 year-old female with a history of Caesarian section ten weeks ago presented with symptoms suggestive of pulmonary embolism. Transthoracic echocardiography revealed a free-floating large thrombus traversing the right atrial cavity. Transesophageal echocardiography confirmed the presence of an unattached thrombus that originated from the most proximal part of the inferior vena cava.

Stem cell transplantation in hematological disorders. A developing country experience-impact of cost considerations.

Objective: To describe the experience in setting up a bone marrow transplant program at Ain Shams University, Cairo, Egypt.

Methods: Sixteen patients were transplanted at Ain Shams University Bone Marrow Transplantation unit from March 2005 to January 2008.

Results: Sixteen patients were transplanted with a median age of 25 years.

Correlation of telomerase activity to apoptosis and survival in adult acute lymphoblastic leukemia: an Egyptian single-center study.

Telomerase is activated in most tumors, but suppressed in normal human somatic cells. Current evidence indicates that telomerase reactivation is a critical step in carcinogenesis, with a close relationship to apoptosis. The goal of this study was to investigate the levels and relationship of telomerase activity to apoptosis and its impact on the survival of Egyptian adult acute lymphoblastic leukemia patients.

Pro-inflammatory cytokines and depression in patients with acute leukemia.

The prevalence of depression among patients diagnosed with cancer is higher than general population and is associated with faster tumor progression and shorter survival time. Cytokines whose primary function is to act as signaling molecules of the immune system have recently also been implicated in the pathogenesis of depression. The aim of present study was to investigate the relation between pro-infammatory cytokines [Interleukin-6 (IL-6) and Tumor Necrosis Factor-alpha (TNF-alpha)], depression and stressful life events in patients with acute leukemia.
