Phosphorus from excess fertilizers and detergents ends up washing into lakes, creeks, and rivers. This overabundance of phosphorus causes excessive aquatic plant and algae growth and depletes the dissolved oxygen supply in the water. In this study, aluminum-impregnated mesoporous adsorbents were tested for their ability to remove phosphate from water. The surface structure of the materials was ...
Clinical scenario A rural hospital hires a new infection control professional, EL, who has just received her master’s degree and trained in infection control departments that were up to date on the best evidence. EL reviews the infection control policies and learns that traditional central line catheters are used. Where she trained, a new,more expensive, antiseptic catheter was used. The new ca...
BACKGROUND In recent years, cranial ventricular catheters impregnated with antimicrobial agents have become available. Theoretically, they provide antibiotic prophylaxis locally without the associated complications of opportunistic nosocomial infections. This study aims to compare antibiotic impregnated catheters with conventional catheters coupled with systemic antibiotics. METHODS Patients ...
OBJECTIVES We assessed the in vitro effect of exposing various bacteria to minocycline/rifampicin-impregnated vascular catheters on the antimicrobial activity of the catheters and the antimicrobial susceptibility of tested organisms. METHODS Segments of minocycline/rifampicin-impregnated catheters were placed in agar plates inoculated with methicillin-susceptible Staphylococcus aureus (MSSA),...
PURPOSE The aim of this study is to review the current evidence-based data regarding strategies for prevention of central venous catheter (CVC) infections at the time of catheter insertion and as a part of routine care. METHODS We conducted a PubMed search from January 1990 to November 2010 using the following keywords: central venous catheter, clinical trials, pediatric, infection, preventio...
Time and manpower constraints associated with acute combat casualty care can make antibiotic bead production at the point of care prohibitively difficult, if not impossible. The purpose of this study is to evaluate our technique for the sterile prefabrication of antibiotic-impregnated polymethylmethacrylate (PMMA) beads in the combat hospital environment by assessing their sterility at the time...
Many efforts have been made to develop amine-based solid adsorbents for capture of CO2 by adsorption. Compared with the traditional process of absorption in aqueous solutions of amines, the adsorbents with amine immobilized in solids generally result in processes with lower capital and energy costs. The literature contains some experimental studies of CO2 adsorption in impregnated materials; ho...
Condensation of water from the atmosphere on a solid surface is an ubiquitous phenomenon in nature and has diverse technological applications, e.g. in heat and mass transfer. We investigated the condensation kinetics of water drops on a lubricant-impregnated surface, i.e., a micropillar array impregnated with a non-volatile ionic liquid. Growing and coalescing drops were imaged in 3D using a la...
STUDY OBJECTIVES To determine the efficacy of an attachable subcutaneous silver-impregnated cuff in preventing local central venous catheter (CVC)-related infection and catheter-related sepsis in critically ill surgical patients. DESIGN A prospective analysis of the use of an attachable subcutaneous silver-impregnated cuff compared with a control group in two consecutive time periods. SETTI...
In this study, a green composite was produced from Oil Palm Trunk Lumber (OPTL) by impregnating oil palm shell (OPS) nanoparticles with formaldehyde resin. The changes of physical, mechanical and morphological properties of the OPS nanoparticles impregnated OPTL as a result of natural weathering was investigated. The OPS fibres were ground with a ball-mill for producing nanoparticles before bei...
