Safety Evaluation of Unibody Endografts for Abdominal Aortic Aneurysm Repair: A Systematic Review and Meta-Analysis.

Background: The unibody bifurcated aortic endograft (AFX/AFX2) has emerged as a treatment option for abdominal aortic aneurysms (AAAs). This systematic review and meta-analysis aimed to evaluate the safety of the unibody endograft.

Methods: A literature search was conducted in Cochrane Library, Scopus, Web of Science, and PubMed.

Outcomes Associated With Cardiac Arrest in Patients in the Cardiac Intensive Care Unit With Cardiogenic Shock.

Cardiac arrest (CA) is common and has been associated with adverse outcomes in patients with cardiogenic shock (CS). We sought to determine the prevalence, patient characteristics, and outcomes of CA in cardiovascular intensive care unit patients with CS. We queried cardiovascular intensive care unit admissions from 2007 to 2018 with an admission diagnosis of CS and compared patients with and without CA.

RRM2 expression in different molecular subtypes of breast cancer and its prognostic significance.

Background: Breast cancer is one of the most common types of cancer. Ribonucleotide reductase (RNR) is a heterodimeric tetramer consisting of two Ribonucleoside-diphosphate reductase large subunits (RRM1) and two Ribonucleoside-diphosphate reductase small subunits (RRM2). RRM2 is the building subunit of RNR that is important for synthesis of Deoxynucleoside triphosphate (dNTP) during S phase of cell cycle during DNA replication.

Shock in the cardiac intensive care unit: Changes in epidemiology and prognosis over time.

Unlabelled: There are few studies documenting the changing epidemiology and outcomes of shock in cardiac intensive care unit (CICU) patients. We sought to describe the changes in shock epidemiology and outcomes over time in a CICU population.

Methods: We included 1859 unique patients admitted to the Mayo Clinic Rochester CICU from 2007 through 2018 with an admission diagnosis of shock.

Combining autologous bone marrow mononuclear cells seeded on collagen sponge with Nano Hydroxyapatite, and platelet-rich fibrin: Reporting a novel strategy for alveolar cleft bone regeneration.

Introduction: The aim of this study was to examine and assess the use of autologous bone marrow mononuclear cells (BMMNCs) combined with platelet-rich fibrin (PRF) and nanohydroxyapatite for bone regeneration as an effective technique for alveolar cleft repair.

Patients And Methods: This study included 20 patients with unilateral alveolar cleft defects and with an age range of 8-15 years. They were divided equally into two groups: Group A, received treatment via the regenerative approach which includes; autologous BMMNCs seeded on a collagen sponge in combination with nanohydroxyapatite and autologous PRF.

In vitro antischistosomal activity of venom from the Egyptian snake Cerastes cerastes.

Introduction:: We studied the potential in vitro antischistosomal activity of Cerastes cerastes venom on adult Schistosoma mansoni worms.

Methods:: Live specimens of the horned viper snake, C. cerastes were collected from the Aswan Governorate (Egypt).

Solvatochromism of dye-labeled dendronized polymers of generation numbers 1-4: comparison to dendrimers.

Two series of dendronized polymers (DPs) of generations = 1-4 with different levels of dendritic substitution (low and high) and a solvatochromic probe at = 1 level are used to study their swelling behavior in a collection of solvents largely differing in polarity as indicated by the Kamlet-Taft parameters. This is done by measuring the UV-Vis spectra of all samples in all solvents and determining the longest wavelength absorptions (). The values fall into a range defined by the extreme situations, when the solvatochromic probe is either fully surrounded by solvent or completely shielded against it.

Radius of proximal isovelocity surface area in the assessment of rheumatic mitral stenosis: Connecting flow to anatomy and hemodynamics.

Background: Echocardiographic assessment of left atrial pressure (LAP) in mitral stenosis (MS) is controversial. We sought to examine the role of the radius of the proximal isovelocity surface area (PISA-r) in the assessment of the hemodynamic status of MS after fixing the aliasing velocity (Val).

Methods And Results: We studied 42 candidates of balloon mitral valvuloplasty (BMV), for whom pre-BMV echocardiography was done and LAP invasively measured before dilatation.

Tissue Doppler-Derived Myocardial Acceleration during Isovolumetric Contraction Predicts Pulmonary Capillary Wedge Pressure in Patients with Significant Mitral Regurgitation.

The aim of this study was to determine whether isovolumic contraction velocity (IVV) and acceleration (IVA) predict pulmonary capillary wedge pressure (PCWP) in mitral regurgitation. Forty-four patients with mitral regurgitation were studied. PCWP was invasively measured.

Simplifying proximal isovelocity surface area as an assessment method of mitral valve area in patients with rheumatic mitral stenosis by fixing aliasing velocity and mitral valve angle.

Unlabelled: We aimed to test the ability of a simple equation using proximal isovelocity surface area method (PISA), created by fixing the angle to 100° and the aliasing velocity to 33 cm/s, to calculate mitral valve area (MVA) and assess severity in patients with rheumatic mitral stenosis (MS).

Methods And Results: In a series of 51 consecutive patients with rheumatic MS, MVA was assessed by four methods, conventional PISA equation (PISAconventional), simple PISA equation (PISAsimple), pressure half time (PHT), and planimetry (PLN) which was taken as the reference method. All methods correlated significantly with PLN with the highest correlation found in case of PISAconventional and PISAsimple (r = 0.
