BACKGROUND/PURPOSE One of the most common complications of the peritoneal dialysis (PD) is the infection of the exit site of the peritoneal catheter. The aim of the present study was to evaluate the efficacy of the subcutaneous gentamicin injection around the cuff as a part of routine treatment of the resistant exit site infection (ESI). METHODS If the exit site remains infected after a 2-wee...

Fatty acids in 42 types of saponified vegetable and animal oils were analyzed by electrospray ionization mass spectrometry (ESI-MS) for the development of their rapid discrimination. The compositions were compared with those analyzed by gas chromatography-mass spectrometry (GC-MS), a more conventional method used in the discrimination of fats and oils. Fatty acids extracted with 2-propanol were...

OBJECTIVES this study aimed to investigate the construct validity and responsiveness of performance-based and self-reported measures of strength, mobility and balance after hip fracture. DESIGN secondary analysis of clinical trial data. SUBJECTS a total of 148 older people undergoing hip fracture rehabilitation. METHODS correlation coefficients assessed construct validity. Internal respon...

INTRODUCTION The Emergency Severity Index (ESI) is an initial measure of patient assessment in the emergency department (ED). It rates patients based on acuity and predicted resource intensity from Level 1 (most ill) to Level 5 (least resource intensive). Already implemented and evaluated in several US hospitals, ESI has yet to be evaluated in a Canadian setting or compared with the five-level ...

The structural characterization of proteins using electrospray ionization mass spectrometry (ESI-MS) has become an important method for understanding protein structural dynamics. The correlation between the structures of proteins in solution and gas phase needs to be understood for the application of ESI-MS to protein structural studies. Hen egg white lysozyme (Lyz) is a small protein with a st...

INTRODUCTION Therapy with fixed orthodontic appliances starts with bracket bonding and ends with debonding of brackets, leaving enamel surface varied. Objective The aim of this pilot study was to examine enamel surface before and after debonding of orthodontic brackets by the use of scanning electron microscopy (SEM). METHODS Epoxy replicas of four patients' premolars indicated for therapy wi...

BackgroundCoarctation of the aorta (CoA) is often treated percutaneously. The aim this study was to describe immediate results percutaneous management native aortic coarctation (NaCoA) and recoarctation (ReCoA) at our institution.MethodsWe identified all patients with NaCoA or ReCoA who underwent dilatation by either balloon angioplasty (BAP) endovascular stent implantation (ESI) between 2011 2...

A prospective study was performed to determine the value of direct molecular testing of whole blood for detecting the presence of culturable and unculturable bacteria and yeasts in patients with suspected bloodstream infections. A total of 464 adult and pediatric patients with positive blood cultures matched with 442 patients with negative blood cultures collected during the same period were re...

Two peptide-oligothymidylic acids, prepared by joining an 11 residue synthetic peptide containing one internal carboxyl group (Asp side chain) to amino-linker-5'pdT6 and amino-linker-5'pdT10 oligonucleotides, were analyzed by matrix-assisted laser desorption/ionization (MALDI) on a linear time-of-flight mass spectrometer and by electrospray ionization (ESI) on a triple-quadrupole system. These ...
