Hope and Hype Push Liquid Biopsies in Oncology

Detecting cancer through tumor DNA circulating in the blood has both possibilities and limitations. Realizing its full potential depends in part on resolving cost and sensitivity issues.

UMEM Educational Pearls - University of Maryland School of Medicine, Department of Emergency Medicine

Typically, if an infant or young child presents to the ED with concern for intracranial hemorrhage (ICH), CT is performed as a rapid diagnostic tool. Now that clinicians are more aware of the radiation associated with head CT, the possible use of ultrasound was studied. Ultrasound is commonly used in the neonatal population for detecting ICH. A study by Elkhunovich et al looked at children younger than 2 years who had cranial ultrasounds preformed. Over a 5 year period, 283 ultrasounds were done on patients between 0 to 485 days old (median 33 days). There were 39 bleeds detected. Ultrasound specificity and sensitivity was calculated by comparing the results with CT, MRI and/or clinical outcome. For significant bleeds, the sensitivity for ultrasound was 81%. The specificity for detecting ICH was 97%.

Introduction to Psychology 1.0 | Flat World Education

The most fundamental emotions, known as the basic emotionsThe emotions of anger, disgust, fear, happiness, sadness, and surprise., are those of anger, disgust, fear, happiness, sadness, and surprise. The basic emotions have a long history in human evolution, and they have developed in large part to help us make rapid judgments about stimuli and to quickly guide appropriate behavior (LeDoux, 2000).LeDoux, J. E. (2000). Emotion circuits in the brain. Annual Review of Neuroscience, 23, 155–184. The basic emotions are determined in large part by one of the oldest parts of our brain, the limbic system, including the amygdala, the hypothalamus, and the thalamus. Because they are primarily evolutionarily determined, the basic emotions are experienced and displayed in much the same way across cultures (Ekman, 1992; Elfenbein & Ambady, 2002, 2003; Fridland, Ekman, & Oster, 1987),Ekman, P. (1992). Are there basic emotions? Psychological Review, 99(3), 550–553; Elfenbein, H. A., & Ambady, N. (2002). On the universality and cultural specificity of emotion recognition: A meta-analysis. Psychological Bulletin, 128, 203–23; Fridlund, A. J., Ekman, P., & Oster, H. (1987). Facial expressions of emotion. In A. Siegman & S. Feldstein (Eds.), Nonverbal behavior and communication (2nd ed., pp. 143–223). Hillsdale, NJ: Lawrence Erlbaum Associates. and people are quite accurate at judging the facial expressions of people from different cultures.

R.E.B.E.L. EM - Xanthochromia Detection: Visual Inspection vs. Spectrophotometry - emdocs

An LP gives providers the ability to perform CSF analysis for red blood cells and detect xanthochromia by visual inspection or spectrophotometry. In most of the world, including the United States, the predominant approach to identifying xanthochromia is visual detection. However, this technique is subjective and considered unreliable by many. Spectrophotometry is a more objective test but, has lower specificity, carries a higher cost and is unavailable in the majority of hospitals.
