Studying alternative approaches for placement of cuffed hemodialysis catheters in hemodialysis patients with bilateral internal jugular vein occlusion.

Introduction: Internal jugular vein occlusion often makes necessary the use of less desirable routes as external jugular, subclavian, and femoral vein approaches in addition to inferior vena cava approaches. This a prospective cross-sectional follow-up study of the alternative approaches for placement of cuffed hemodialysis catheters in end-stage renal disease patients with bilateral internal jugular vein occlusion from the interventional nephrology point of view.

Method: The study was conducted on 134 end-stage renal disease patients who were referred for insertion of a challenging hemodialysis catheter due to bilateral internal jugular vein occlusion.

How assembly matters to catalysis and thermal conductivity mediated by CuO nanoparticles.

CuO nanostructures (NSs) of different morphologies were prepared, applied as catalysts for the pyrolysis of sugarcane bagasse (PSCB), and applied for thermally-conductive nanofluids. Both size and shape of the prepared NSs ranged from 5 to 1000 nm, and from nanodots (NDs) to spindle nano-aggregates (NAs), respectively. The catalytic activity of these NSs towards the PSCB was followed up by thermogravimetric analysis (TGA), where they increased the percentage of total weight loss, and lowered the decomposition temperatures of PSCB.
