BACKGROUND The standard diagnostic approach in patients with suspected deep vein thrombosis is to repeat the compression ultrasonography after 1 week in all patients with an initial normal result. We hypothesized that a normal finding of a D-dimer assay safely obviates the need for repeated ultrasonography. In addition, we evaluated the potential value of a pretest probability assessment for th...

INTRODUCTION The current study aimed at investigating the existence of the cross state-dependent learning between morphine and scopolamine (SCO) in mice by passive avoidance method, pointing to the role of CA1 area. METHODS The effects of pre-training SCO (0.75, 1.5, and 3 μg, Intra-CA1), or morphine (1, 3, and 6 mg/kg, intraperitoneal (i.p.) was evaluated on the retrieval of passive avoidanc...

BACKGROUND Biomedical Informatics (BMI) education in medical schools is developing a sound curricular base, but there are few published reports of their educational usefulness. The goal of this paper is to assess knowledge change and satisfaction in medical students after a BMI curriculum. METHODS The National Autonomous University of México Faculty of Medicine (UNAM) recently implemented a c...

OBJECTIVES Recent developments in computer and video technology, multimedia resources enter quickest way possible into medical education and have started to gain popularity. The aim of this study is to evaluate the impact of video-supported lectures on leaning, with comparison to traditional lectures. METHODS According to lecture techniques, two separate groups; one is the traditional lecture...

OBJECTIVES To assess the likelihood ratios of diagnostic strategies for pulmonary embolism and to determine their clinical application according to pretest probability. DATA SOURCES Medline, Embase, and Pascal Biomed and manual search for articles published from January 1990 to September 2003. STUDY SELECTION Studies that evaluated diagnostic tests for confirmation or exclusion of pulmonary...

ResMed Autoset (AS) is a simplified diagnosis system for obstructive sleep apnoea/hypopnoea syndrome (OSAS) based on the respiratory flow/time relationship by pressure variation measured through simple nasal prongs. A multicentre prospective trial was used to compare AS and polysomnography (PSG) for diagnosing 95 patients, with suspected OSAS. Physicians gave a pretest probability of the patien...

In adults, dietary protein seems to induce weight loss and dairy proteins may be insulinotropic. However, the effect of milk proteins in adolescents is unclear. The objective was to test whether milk and milk proteins reduce body weight, waist circumference, homeostatic model assessment, plasma insulin, and insulin secretion estimated as the plasma C-peptide concentration in overweight adolesce...

The purpose of this study was to determine the effect of investigative laboratory integration on student content knowledge and science process skill achievement across learning styles. Treatment groups utilized one of three levels of treatment: subject matter approach without laboratory experimentation, subject matter approach with prescriptive laboratory experimentation, and subject matter app...

The purpose of this study was to examine relationships between pitch-matching and grade level, sex, ethnicity, and classroom teachers’ use of music among K-3 students (N = 289) taught by the same general music teacher. Portions of the data from a pitchmatching exercise that functioned as the music teacher’s roll-taking procedure during the 2005-06 school year were treated as preand posttests. T...

Education is a critical component of the National Blueprint to eliminate racial disparities in diabetes. Research indicates that traditional methods of diabetes education has had limited effectiveness with minority populations and suggests that different educational approaches be explored. The purpose of the research was to explore the effectiveness of an emergent technology (podcast) for use i...
