Review Meta Analysis Comparative Study
Predictive Value of Computed Tomography in Acute Pulmonary Embolism: Systematic Review and Meta-analysis.
Many computed tomography (CT) parameters have been proposed as potential predictors of outcome in acute pulmonary embolism. We sought to summarize available evidence on the predictive value of CT severity parameters for short-term clinical outcome in pulmonary embolism. ⋯ Across all end points, the RV/LV diameter ratio on transverse CT sections has the strongest predictive value and most robust evidence base for adverse clinical outcomes in patients with acute pulmonary embolism.

Substantial Discrepancy Between Fluid and Weight Loss During Acute Decompensated Heart Failure Treatment.
Net fluid and weight loss are used ubiquitously to monitor diuretic response in acute decompensated heart failure research and patient care. However, the performance of these metrics has never been evaluated critically. The weight and volume of aqueous fluids such as urine should be correlated nearly perfectly and with very good agreement. As a result, significant discrepancy between fluid and weight loss during the treatment of acute decompensated heart failure would indicate measurement error in 1 or both of the parameters. ⋯ Considerable discrepancy between fluid balance and weight loss is common in patients treated for acute decompensated heart failure. Awareness of the limitations inherent to these commonly used metrics and efforts to develop more reliable measures of diuresis are critical for both patient care and research in acute decompensated heart failure.

A Brief Patient Self-administered Substance Use Screening Tool for Primary Care: Two-site Validation Study of the Substance Use Brief Screen (SUBS).
Substance use screening is widely encouraged in health care settings, but the lack of a screening approach that fits easily into clinical workflows has restricted its broad implementation. The Substance Use Brief Screen (SUBS) was developed as a brief, self-administered instrument to identify unhealthy use of tobacco, alcohol, illicit drugs, and prescription drugs. We evaluated the validity and test-retest reliability of the SUBS in adult primary care patients. ⋯ The SUBS was feasible for self-administration and generated valid results in a diverse primary care patient population. The 4-item SUBS can be recommended for primary care settings that are seeking to implement substance use screening.
