OBJECTIVES Implementation of the International Statistical Classification of Disease and Related Health Problems, 10th Revision (ICD-10) coding system presents challenges for using administrative data. Recognizing this, we conducted a multistep process to develop ICD-10 coding algorithms to define Charlson and Elixhauser comorbidities in administrative data and assess the performance of the res...

BACKGROUND/AIMS We used high-resolution impedance manometry (HRIM) to determine the length of breaks on the isobaric contour which would predict incomplete bolus clearance in patients in the sitting position. METHODS In total, 651 swallows in 71 patients with esophageal symptoms were studied using a solid-state HRIM system in the sitting position. Each swallow was classified as complete or in...

Plots naturally infested with Rotylenchulus reniformis were sampled in the spring of 2006 and 2007 at depths of 15 and 30 cm in the bed, furrow over the drip tape, and "dry" furrow, and at approximately 40 to 45 cm depth in the bed and dry furrow. Then, 1,3-dichloropropene (Telone EC) was injected into the subsurface drip irrigation at 46 kg a.i./ha, and 3 to 4 weeks later the plots were resamp...

introduction: during radiotherapy, high accuracy in the dose delivery is required because there is a strong  relationship between the absorbed dose, local tumor control and particularly the normal tissue damage. in  many institutions, in vivo dosimetry using diodes is performed to check the actual dose delivered. in general,  the uncertainty in the dose delivered should fall within  ± 5% of the...

Fig, 1: Structure of phenylaceticacid hydrazones and 2-chlorophenylsemicarbazones. Antidepressant activity was evaluated in albino rats weighing 100 to 120 g, by Porsolt forcecll swimming test (4). Rats were individually placed in plexiglass cylinders (height 40 cm; diameter 18 cm), containing 15 cm of water maintained at 25°C. After 15 minutes they were removed to a 30°C drying room for 30 min...

Double Langmuir probe measurements are presented over a two-dimensional array of locations in the near Discharge Cathode Assembly (DCA) region of a 30-cm diameter ring cusp ion thruster. Discharge plasma data taken with and without beam extraction exhibit a broadening of the high on-axis electron temperature region when a beam is extracted. Electron number density and temperature contours are p...

PURPOSE Although showing a 25% reduction in the biopsy prevalence of cancer compared with placebo in the Prostate Cancer Prevention Trial, finasteride was associated with a higher prevalence of high-grade disease. This observation was driven by "for-cause" biopsies. We sought to understand how volume-dependent changes in prostate-specific antigen test performance characteristics may have contri...

The objective of this work was to study the effects of tillage and liquid manure applications on some physical and chemical properties as well as on the carbon and nitrogen mineralization potential of a meadow soil. Our results indicated that tillage and manure applications had no effect on the concentration of Cu, Mn, total N and organic C in 0-15 cm layer of soil after 15 years of treatment. ...

Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous organic pollutants in urban environments and are considered as the priority pollutants by the U.S. Environmental Protection Agency. The objective of this study was to determine the depth-wise distribution (0–15, 15–30, and 30–45 cm) of 16 PAHs compounds in four urban soils of different land uses (residential, public parks, public buildings,...
