Input: Consider Input: Abstract: Information obtained for all persons with the acquired immunodeficiency syndrome (AIDS) reported to the Centers for Disease Control, Atlanta, includes a question about employment in a health care or clinical laboratory setting. As of May 1, 1986, a total of 922 (5.5%) of 16,748 adults with AIDS reported employment in such settings. Ninety-five percent of these health care workers belonged to recognized high-risk groups for AIDS; the proportion with "no identified risk" has not increased with time. All AIDS patients (including health care workers) who do not belong to high-risk groups are referred for further investigation. Of 88 health care workers initially reported with no identified risk, ten were from countries where heterosexual transmission is believed to play a major role; additional information was unobtainable or incomplete for 17 individuals. Of 61 persons on whom interviews or other follow-up information was obtained, 44 (73%) were reclassified. Specific occupational exposures that could be implicated as the source of human immunodeficiency virus infection were not identified for any health care workers with AIDS. A review of surveillance data supports other studies indicating that the risk of human immunodeficiency virus transmission in the occupational setting is low.

Input: Consider Input: Abstract: To examine the gastric emptying characteristics of selected test drinks varying in carbohydrate composition and concentration, twenty-five runners ingested 400 ml of a solution in one or more of a series of trials followed by either 15 min seated rest or 15 min running (50 to 70% VO2 max). The solutions tested at rest included water, 5.0% maltodextrin, 3.0% maltodextrin + 2% glucose (MG5.0), and 4.5% maltodextrin + 2.6% fructose (MF7.1). Solutions tested during running included water, MG5.0, MF7.1, 5.5% maltodextrin + 2% glucose, and 5.5% maltodextrin + 2% fructose. At rest and during running, water emptied significantly (P less than 0.5) faster than all other drinks. In the running trials, the volume of gastric residue of 5.5% maltodextrin + 2% fructose (221.7 +/- 11.0 ml) was significantly greater than water (103.4 +/- 19.0 ml), MG5.0 (153.3 +/- 16.8 ml), and MF7.1 (167.3 +/- 14.8), suggesting an inhibitory role of glucose on gastric emptying. Running resulted in a significantly lower volume of gastric residue of water, MG5.0, and MF7.1 (103.4 +/- 19.0, 153.3 +/- 16.8, and 167.3 +/- 14.8 ml, respectively) as compared to the corresponding drinks at rest (209.3 +/- 12.6, 287.7 +/- 16.0, and 271.0 +/- 17.8 ml, respectively). These results suggest a possible advantage for including maltodextrin and fructose as carbohydrate sources in athletic drinks. Furthermore, the rate of gastric emptying is enhanced while running, possibly due to increased mechanical movement of fluid within the stomach.

Input: Consider Input: Abstract: The case of a man who injected turpentine intravenously in an attempt to kill himself is reported. The patient developed immediate pulmonary edema and hypoxia, followed later by cellulitis at the site of injection. Although only one death to date has been attributed to this form of chemical abuse, extensive local reactions, pulmonary involvement, central nervous system depression, and febrile reactions should be anticipated, and such patients should be admitted to the hospital. Patients should be observed for local reactions and myonecrosis around the site of injection, especially as these occur 12-24 hours later.
