ED Syncope Workup: After H and P, ECG is the Only Test Required for Every Patient.....

Conclusions: Many unnecessary tests are obtained to evaluate syncope. Selecting tests based on history and examination and prioritizing less expensive and higher yield tests would ensure a more informed and cost-effective approach to evaluating older patients with syncope._____________________________________________________________________________4)    Reed MJ.  The ROSE (Risk Stratification of syncope in the emergency department) Study.  J Am Coll Cardiol, 2010; 55:713-721, doi:10.1016/j.jacc.2009.09.049  Objectives: The aim of this study was to develop and validate a clinical decision rule (CDR) to predict 1-month serious outcome and all-cause death in patients presenting with syncope to the emergency department.  Background: Syncope is a common, potentially serious condition accounting for many hospital admissions.   Methods: This was a single center, prospective, observational study of adults presenting to the emergency department with syncope. A CDR was devised from 550 patients in a derivation cohort and tested in a validation cohort of a further 550 patients.  Results: One-month serious outcome or all-cause death occurred in 40 (7.3%) patients in the derivation cohort. Independent predictors were brain natriuretic peptide concentration greater than 300 pg/ml (odds ratio [OR]: 7.3), positive fecal occultblood (OR: 13.2), hemoglobin less than 90 g/l (OR: 6.7), oxygen saturation less than 94% (OR: 3.0)...

GudasAbstractEthanol (EtOH) is a recreationally ingested compound that is both teratogenic and carcinogenic in humans. Because of its abundant consumption worldwide and the vital role of stem cells in the formation of birth defects and cancers, delineating the effects of EtOH on stem cell function is currently an active and urgent pursuit of scientific investigation to explicate some of the mechanisms contributing to EtOH toxicity. Stem cells represent a primordial, undifferentiated phase of devel...

Lian, K.J. McClellanAbstractUranium diboride (UB2) and uranium tetraboride (UB4) are candidate constituents for multi-phase accident tolerant fuel due to their anticipated high thermal conductivity. These fuels have high uranium density that contributes to fission, and by tailoring the ratio of 10B/11B, can also act as an integrated burnable poison. Understanding the thermophysical and mechanical properties of uranium borides, for w...

Accordingly, in this work, the lignin-vinyl acetate monomer (LVAc) and its copolymers were synthesized successfully. To obtain the LVAc, firstly, lignin was activated with the amine using diethylenetriamine (DETA) and then followed by the grafting with chlorovinyl aceta...

In this study, we introduce a novel approach with high digestion efficiency that involves using Fenton’s reagent and nitric acid to remove feces solids. Firstly, Fenton’s reagent was used to degrade small solids and decompose large solids into small pieces. Secondly, nitric acid was used to digest the remaining solids and filters. Furthermore, absolute ethyl alcohol was used to remove the mineral residues wrapped on the plastic surfaces and disperse MPs. By using this method, 97.78 % MPs can be recovered from human and chicken feces, and no significant changes were observed in the physical and Raman spectral pr...
