Impact of Diagnostic Stewardship on Urine Culture Ordering in Saudi Arabia: Prospective Pre- and Postintervention Study

Impact of Diagnostic Stewardship on Urine Culture Ordering in Saudi Arabia: Prospective Pre- and Postintervention Study

We analyzed categorical data using a chi-square test or Fisher exact test, as appropriate, and continuous data using a Student t test. We also used a multivariable logistic regression model, adjusting for age, sex, diabetes mellitus, and chronic kidney disease, to evaluate the association between our CDS intervention and inappropriate urine culture orders and unnecessary antibiotic use. All analyses were conducted in STATA/BE (version 18; Stata Corp).

Deep Learning–Based Precision Cropping of Eye Regions in Strabismus Photographs: Algorithm Development and Validation Study for Workflow Optimization

Deep Learning–Based Precision Cropping of Eye Regions in Strabismus Photographs: Algorithm Development and Validation Study for Workflow Optimization

This method uses the cross-entropy function to optimize probabilities around the label y, concentrating the network distribution near the label values. The final overall loss is derived by combining these 2 components with appropriate weighting. We implement a method for calculating the skew IOU, incorporating triangulation. Figure 2 illustrates the geometric principles. Our objective is to calculate the IOU for each pair of skew rectangles.

Fourier Transform Analysis of GPS-Derived Mobility Patterns for Diagnosis and Mood Monitoring of Bipolar and Major Depressive Disorders: Prospective Study

Fourier Transform Analysis of GPS-Derived Mobility Patterns for Diagnosis and Mood Monitoring of Bipolar and Major Depressive Disorders: Prospective Study

Periodic waves corresponding to the top five power values were identified, with their summed ranks on the y-axis used to indicate intensity (see Figure 3 D). Lower ranks reflected stronger intensity, highlighting shared periodic waves (x-axis) among participants. The period indicates the reciprocal of the frequency. The ranking score indicates the power spectrum in descending order from the maximum value. Figure 4 shows differences in periodic waves between groups for LV and entropy.
