Question: Abstract: In order to test the widely held assumption that homeopathic medicines contain negligible quantities of their major ingredients, six such medicines labeled in Latin as containing arsenic were purchased over the counter and by mail order and their arsenic contents measured. Values determined were similar to those expected from label information in only two of six and were markedly at variance in the remaining four. Arsenic was present in notable quantities in two preparations. Most sales personnel interviewed could not identify arsenic as being an ingredient in these preparations and were therefore incapable of warning the general public of possible dangers from ingestion. No such warnings appeared on the labels.
Which is the apt title for the abstract? option1: Arsenic content of homeopathic medicines. option2: Sensitivity of the Denver Developmental Screening Test in speech and language screening.

Answer: Arsenic content of homeopathic medicines.

Question: Abstract: Systemic and splanchnic haemodynamics were studied in patients with cirrhosis who had been classified in three groups (A, B, and C) according to the degree of liver failure (modified Pugh's classification). In patients of group A, cardiac index was significantly lower than that of group C and systemic vascular resistance was higher, but not significantly so, than that of patients with liver failure. Wedged hepatic venous pressure was significantly lower in the former group than in the latter. In patients in group B, corresponding values fell between those of groups A and C. Azygos blood flow averaged 0.477 +/- 0.242 l/min (mean +/- SD) in group A and it was significantly lower than in groups B and C (0.642 +/- 0.224 and 1.061 +/- 0.476 l/min, respectively). In the three groups, acute administration of propranolol induced statistically significant changes in systemic and splanchnic haemodynamics. In patients of group C but not of group B, the mean value of azygos blood flow after propranolol remained significantly higher than in group A. Moreover, the fraction of azygos blood flow to cardiac output decreased in groups A and B while slightly increased in group C. This study shows that in patients with cirrhosis, the degree of liver failure may be a determinant for the haemodynamic responses to drugs acting on portal hypertension.
Which is the apt title for the abstract? option1: Influence of the degree of liver failure on systemic and splanchnic haemodynamics and on response to propranolol in patients with cirrhosis. option2: The risks of moderate drinking [letter]

Answer: Influence of the degree of liver failure on systemic and splanchnic haemodynamics and on response to propranolol in patients with cirrhosis.

Question: Abstract: This prospective study evaluated the use of basic vital signs, two mechanisms of injury, and time-distance factors as field triage criteria for on-scene helicopter transport of 130 patients to a trauma center serving a rural area. The vital signs criteria included any one or more of the following: level of consciousness (LOC) less than or equal to unresponsive to verbal stimulation; respiration rate (RR) less than or equal to 10 or greater than or equal to 30; systolic blood pressure (BP) less than or equal to 90; pulse (P) less than or equal to 60 or greater than or equal to 120. The flight crew recorded vital signs taken by the first responder capable of basic assessment. Entrapment and associated fatalities in motor vehicular accidents were recorded and flight logistics were examined. The presence of one or more abnormal signs identified a group of seriously injured trauma patients (mean Injury Severity Score = 29.1) with 24% mortality compared to a predicted mortality of 32% (p less than 0.02). Unresponsiveness to verbal stimulation in the field was the single most predictive criterion, yielding sensitivity of 93% and specificity of 85%. Time-distance criteria were helpful to determine helicopter use.
