Mixed linear models are assumed in most animal breeding applications. Convenient methods for computing BLUE of the estimable linear functions of the fixed elements of the model and for computing best linear unbiased predictions of the random elements of the model have been available. Most data available to animal breeders, however, do not meet the usual(More)
This study compared the complication rates of tube thoracostomy performed in the emergency department (ED) versus the operating room (OR) and the inpatient ward (IW). A retrospective case series of all patients at an urban, university-based level 1 trauma center hospital who received tube thoracostomy for any indication between 1/1/93 and 12/31/93 was(More)
Procedures are described to estimate variances when heterogeneity of genetic and residual dispersion parameters exists for some criterion. Genetic and residual variances are considered to follow distributions with either known or unknown parameters. The estimates of variances obtained are weighted averages of the corresponding parameter and of a data-based(More)
The model generally considered in analysis of covariance has all levels of classification factors and interactions fixed, and also covariate regression coefficients fixed. Mixed models are more appropriate in most applications. A summary of estimation and hypothesis testing for analysis of covariance in the mixed model, including the case of random(More)
OBJECTIVE The objective of the study was to evaluate the impact of an electronic health record (EHR) on documentation completeness and patient care in a labor and delivery unit. STUDY DESIGN We conducted a pre- and postintervention study to compare documentation quality and workflow before and after EHR implementation. Documentation was compared using(More)
Auditory brainstem response (ABR) has been used by several investigators to study the role of the brain stem in the pathophysiology of obstructive sleep apnea (OSA). These studies have produced conflicting results. We studied 27 preoperative OSA patients and 17 controls using click stimuli presented at a slow (11.7/second) rate and at a fast (57.7/second)(More)
This multicenter, randomized, double-blind study compared the efficacy and tolerability of ondansetron 8 mg twice daily for 3 days with placebo in preventing nausea and vomiting in 81 patients receiving cyclophosphamide-doxorubicin-based chemotherapy. The first dose of study drug was administered 30 minutes before the initiation of chemotherapy. Patients(More)
Whether to select for longer life in the herd or shorter calving interval depends on the genetic and phenotypic relationships among herd life, amount of milk in first lactation, and calving interval. Herd life and average calving intmwal are essentially phenotypically uncorrelated. The phenotypic and genetic correlations of herd life and milk in first(More)
