OBJECTIVE The National Institute on Alcohol Abuse and Alcoholism (NIAAA) has developed a two-question tool for the detection of unhealthy drinking (NIAAA-2Q) that investigates excessive alcohol consumption per single occasion. NIAAA-2Q can be commuted into a four-question tool (NIAAA-4Q) by the addition of two questions aimed at investigating excessive weekly alcohol intake. NIAAA-2Q and NIAAA-...

STUDY OBJECTIVES Transient changes in heart rate associated with obstructive apneas have been suggested for screening of sleep disordered breathing (SDB). This study prospectively compares the outcomes of an automated ECG-based SDB screening tool with simultaneous polysomnography. METHODS The previously-developed automated algorithm was applied to a single channel ECG obtained during standard...

STUDY OBJECTIVE We investigate the performance characteristics of bedside emergency department (ED) ultrasonography by nonradiologist physician sonographers in the diagnosis of ileocolic intussusception in children. METHODS This was a prospective, observational study conducted in a pediatric ED of an urban tertiary care children's hospital. Pediatric emergency physicians with no experience in...

Ultrasound-based transient elastography (TE) is a promising noninvasive alternative to liver biopsy for the detection of hepatic fibrosis due to recurrent hepatitis C virus (HCV) after liver transplantation (LT). However, its overall test performance in various settings remains unknown. The aim of this study was to perform a systematic review and diagnostic accuracy meta-analysis of studies com...

introduction: in cases with potential diagnosis of ischemic chest pain, screening high risk patients for adverse outcomes would be very helpful. the present study was designed aiming to determine the diagnostic accuracy of thrombolysis in myocardial infarction (timi) score in patients with potential diagnosis of ischemic chest pain. method: this diagnostic accuracy study was designed to evaluat...

introducation: emotion regulation and thought-action fusion (taf) are among the most important components which cause psychological disorders. the present study aimed to predict somatoform disorder regarding the emotion regulation and taf in female students of the savadkuh county. methods:   in this descriptive correlation study, 110 middle school female students in the city of savadkuh in the ...

ity scale for clinicians is symmetrically skewed in both directions. In primary care, elective surgery, and oncology, clinicians work at the extremes of the probability scale. The time has come to apply the Feynman-Tufte principle to clinical logic, to offer a visual representation of Bayesian logic. Earlier attempts with natural logarithmics do not allow a simple graphic. We teach a scale of l...

Data Synthesis: 172 studies evaluated diagnostic accuracy. For identifying clinically significant fibrosis, the platelet count, age– platelet index, aspartate aminotransferase–platelet ratio index (APRI), FibroIndex, FibroTest, and Forns index had median positive likelihood ratios of 5 to 10 at commonly used cutoffs and areas under the receiver-operating characteristic curve (AUROCs) of 0.70 or...
