Molecular Identification of OXA Carbapenemase-Encoding Genes in Isolated from Patients in Critical Care in Egypt.

The emergence of carbapenem-resistant (CRAB) in hospitals, particularly within critical care units, has garnered substantial global concern. CRAB commonly arises from the degradation by various ß-lactamases. : We aimed to assess OXA-type carbapenemases in clinical isolates of obtained from an Egyptian tertiary care facility.

Inpatient treatment modalities of coronavirus disease 2019 in the Egyptian population: A bi-center retrospective observational study.

Background: Many protocols for the treatment of coronavirus disease 2019 (COVID-19) have been published. In addition to an abundance of studies and meta-analyses on the treatment of COVID-19, different medications used in the intensive care unit will have a significant impact on mortality. The study attempted to highlight, compare, and quantify the impact on outcomes.

Comparing the therapeutic potentials of vs. against vulvovaginal candidiasis in female rats: an study.

Background: Vulvovaginal candidiasis (VVC) is a highly prevalent illness affecting women globally. Lactobacilli, which make up the majority of healthy vaginal microbiota (VMB), serve as a powerful barrier against infections. Probiotic therapy has been recommended for the treatment or prevention of VVC.

Hypoxemia After Endobronchial Valve Deployment for Persistent Air Leak.

Endobronchial valves (EBVs) are a novel, minimally invasive bronchoscopic management technique for persistent air leaks that fail conservative therapy. Currently, 2 EBVs are available in the United States: the Spiration Valve System (Olympus, Redmond, WA) and the Zephyr Valve (Pulmonx, Redwood, CA). These valves are Food and Drug Administration-approved to reduce hyperinflation in emphysematous patients via bronchoscopic lung-volume reduction.

Synthesis and Evaluation of High Functionality and Quality Cell-penetrating Peptide Conjugated Lipid for Octaarginine Modified PEGylated Liposomes In U251 and U87 Glioma Cells.

The use of peptide ligand modified PEGylated liposomes has been widely investigated for tumor targeting. Peptides are mainly inserted in the liposomal lipid bilayer using PEG-lipid spacer (Peptide-PEG-DSPE). However, a lower cellular uptake from longer nonlinear PEG spacer was reported, we here synthesized a high functionality and quality (HFQ) lipid with a short, linear serine-glycine repeated peptide [(SG)] spacer.

Comparison of Changes in PPV Using a Tidal Volume Challenge with a Passive Leg Raising Test to Predict Fluid Responsiveness in Patients Ventilated Using Low Tidal Volume.

Background: Tidal volume challenge pulse pressure variation (TVC-PPV) is considered one of the recent reliable dynamic indices of fluid responsiveness (FR); also, passive leg raising (PLR)-induced changes in cardiac output (CO) detected by echocardiography are considered a reliable reversible self-fluid challenge test; many patients share eligibility for both tests.

Objectives: The study aimed to compare the sensitivity and specificity of both tests for the prediction of FR in mechanically ventilated patients with hemodynamic instability.

Methods: We studied 46 patients.

Chitosan caged liposomes for improving oral bioavailability of rivaroxaban: and evaluation.

In this study, chitosan (CS) caged classic liposomes (CLs) and flexible liposomes (FLs) were developed to enhance the oral bioavailability of rivaroxaban (RVX) in the fasted condition. The prepared formulations were subjected to physicochemical characterization included: FTIR, DSC, zeta potential, particle size, polydispersity index, entrapment efficiency, dissolution, and transmission electron microscope imaging. The selected formulation (RVX-TFL2) composed of PL S100/Tween 80 (85/15% w/w) and coated with CS solution in the strength of (0.

Aortic Dysfunction in Mitral Regurgitation Due to Floppy Mitral Valve/Mitral Valve Prolapse.

Background:  Floppy mitral valve/mitral valve prolapse (FMV/MVP), a heritable disorder of connective tissue, often leads to mitral regurgitation (MR) and is the most common cause for mitral valve surgery in developed countries. Connective tissue disorders may affect aortic function, and a stiff aorta may increase the severity of MR. Aortic function, however, has not been studied in FMV/MVP with MR.

Does Uterine Fibroid Adversely Affect Obstetric Outcome of Pregnancy?

Background: Fibroid is the most common benign tumor of the uterus and if associated with pregnancy may adversely affect the outcome of pregnancy. Objective of the present study was to assess the obstetric outcome (maternal and fetal) in pregnancy with fibroid.

Methods: A prospective observational study was performed over a period from May 2015 to August 2017 at Obstetrics and Gynecology Department in Zagazig University Hospitals, Egypt.

The association of IL-33 and Foxp3 gene polymorphisms with recurrent pregnancy loss in Egyptian women.

Deregulated immunity is one of the most important factors implicated in recurrent pregnancy loss (RPL). The possible role of interleukin-33 (IL-33) and forkhead/winged helix transcription factor (Foxp3) in RPL have not been fully investigated. We aimed to evaluate IL-33 rs1929992 and Foxp3 rs2232365 single nucleotide polymorphisms (SNPs) and their serum levels in Egyptian RPL females.

Could Metformin Manage Gestational Diabetes Mellitus instead of Insulin?

Gestational diabetes mellitus (GDM) complicates a significant number of pregnancies. Blood glucose control improves perinatal outcomes. Medical nutrition therapy is the foundation in management.

Development and validation of an HPLC-UV method for the quantification of carbamazepine in rabbit plasma.

An isocratic simple rapid assay has been developed and validated for the determination of carbamazepine (CBZ) in both solution form and rabbit plasma using propylparaben as an internal standard. The assay was performed using a μ-Bondapak C18 (150 mm × 4.6 mm i.

Comparative bioavailability study of cefuroxime axetil (equivalent to 500 mg cefuroxime/tablet) tablets (Zednad® versus Zinnat®) in healthy male volunteers.

This study was performed to investigate the bioequivalence of cefuroxime axetil tablets between a generic test product (A) Zednad® Tablet (500 mg cefuroxime/ tablet, Diamond Pharma, Syria), and the Reference Product (B) Zinnat® Tablet (500 mg cefuroxime/tablet, GlaxoSmithKline, Saudi Arabia). The bioavailability study was carried out for 24 healthy male volunteers. The subjects received 1 Zednad® Tablet (500 mg/ tablet) and 1 Zinnat® Tablet (500 mg/tablet) in a randomized, two-way crossover design fashion on 2 treatment days, after an overnight fast of at least 10 h, with a washout period of 7 days.

Effect of laparoscopic ovarian drilling on vascular endothelial growth factor and ovarian stromal blood flow using 3-dimensional power Doppler.

Objective: To determine, by using 3-dimensional power Doppler ultrasonography, the effect of laparoscopic ovarian drilling (LOD) on the serum level of vascular endothelial growth factor (VEGF) and ovarian stromal blood flow changes in polycystic ovary syndrome (PCOS).

Methods: A prospective controlled clinical study was conducted on 26 clomiphene-resistant women with PCOS who were scheduled for LOD and a control group of 22 fertile regularly menstruating women. VEGF and 3 ovarian Doppler indices-vascularization index, flow index, and vascularization flow index-were measured and compared between the 2 groups, and before and after LOD in the PCOS group.

Optimization of 5-flurouracil solid-lipid nanoparticles: a preliminary study to treat colon cancer.

Solid lipid nanoparticle (SLNs) formulae were utilized for the release of 5-flurouracil (5-FU) inside the colonic medium for local treatment of colon cancer. SLNs were prepared by double emulsion-solvent evaporation technique (w/o/w) using triglyceride esters, Dynasan™ 114 or Dynasan™ 118 along with soyalecithin as the lipid parts. Different formulation parameters; including type of Dynasan, soyalicithin:Dynasan ratio, drug:total lipid ratio, and polyvinyl alcohol (PVA) concentration were studied with respect to particle size and drug entrapment efficiency.
