HYPOTHESES (1) Antibiotic restriction policies result in alteration of microbiologic features of surgical site infections (SSIs) and (2) reported SSI rates are underestimated when postdischarge surveillance is not included in SSI surveillance efforts. DESIGN Retrospective analysis of prospectively collected SSI surveillance data. PATIENTS AND METHODS We compared initial microbial isolates f...

BACKGROUND AND AIM Significant bone loss develops in the first months and continues years after spinal cord injury. A cross - sectional comparative study was performed to evaluate factors influencing bone loss in spinal cord injured men with paraplegia. PATIENTS AND METHODS We studied 31 paraplegic men in chronic stage (>1.5 years) in comparison with 30 able-bodied men of similar age, height,...

Osteoporosis is a disease that is strongly genetically determined. Aromatase converts androgens to estradiol in postmenopausal women, therefore polymorphisms of the gene for this enzyme may be associated with bone mass and fracture. We investigated the association of the TTTA microsatellite polymorphism in intron 4 of the aromatase (CYP19) gene with bone mineral density (BMD) and fracture in 1,...

in eastern austria, alfalfa is usually grown as a rainfed crop in crop rotations in organic farming systems, where yearto- year rainfall fluctuations cause different levels of drought stress. to identify the suitability of different alfalfa genotypes and drought tolerance indices, 18 contrasting alfalfa genotypes were evaluated under irrigated and rainfed conditions at the research station of t...

PURPOSE We determined the effect of Fourier-domain optical coherence tomography (OCT) signal strength index (SSI) and cropping on retinal nerve fiber layer (RNFL) and macular ganglion cell complex (GCC) scan repeatability and measurement thickness. METHODS Eyes were enrolled in the longitudinal Advanced Imaging for Glaucoma Study. At each visit, three repeat scans from the optic nerve head an...

Surveillance of surgical-site infections (SSI), with feedback of appropriate data to surgeons, has been shown to be an important component of strategies to reduce SSI risk. For SSIs, the traditional wound classification system, which stratifies each wound into one of four categories (clean, clean-contaminated, contaminated, and dirty-infected), has been available since 1964. Limitations of this...

OBJECTIVE Establishing the effectiveness of the National Nosocomial Infection Surveillance System (NNIS) and Study of the Efficacy of Nosocomial Infection Control's (SENIC) prognostic surgical site infection (SSI) indices in Colombian hospitals and assessing the influence of other risk factors. METHODS A prospective, multicentre cohort study was conducted in five Colombian hospitals. All pati...

More than 40 heat indices are being used across the world to quantify outdoor thermal comfort. The selection of an Outdoor Heat Stress Index (OHSI) depends on several parameters, including clothing, age, awareness, local environment, food consumption, human activities, and resources. This study investigates various indicators stress, (i) OHSIs officially stress worldwide, (ii) estimation method...

BACKGROUND We sought to identify risk factors for surgical site infections (SSI) in children undergoing cardiac surgery. METHODS A matched case-control study was conducted in the Children's Hospital Boston Cardiovascular Program. Surgical site infections were identified for 3 years (2004 to 2006). We identified two randomly selected control patients who underwent cardiac surgery within 7 days...
