Betel quid and reaction time.

Fifteen male Yapese students participated in an experiment to see if the betel quid (betel nut, piper leaf, and calcium hydroxide) has overt effects on simple reaction time latencies. The data indicate that the entire quid produces discernible behavioral effects that are manifested in a relatively short time period following quid ingestion. Reaction time latencies lengthened following quid ingestion during the first 20 reaction time trials or within an apparent initial 5 minute interval.

Malabsorption of hemoglobin iron in pernicious anemia: correction with intrinsic factor--containing substances.

Hemoglobin iron absorption in patients with treated prenicious anemia (PA) and concomitant iron deficiency was low compared to absorption in patients with iron deficiency alone. Crude and purified hog intrinsic factor (IF) concentrates doubled the absorption of hemoglobin iron in these patients as did normal (neutralized depepsinized) human gastric juice. Hemoglobin iron absorption was not significantly enhanced by PA gastric juice. Absorption of heme iron, like that of hemoglobin iron, was enhanced by normal neutralized depepsinized gastric juice. No enhancement of hemoglobin iron absorption by these substances was obtained in the normal or iron-deficient non-PA control subjects. Preincubation of the hog IF concentrate with antisera to IF significantly reduced the enhancement of hemoglobin iron absorption due to the concentrate. In vitro studies suggest that heme complexes with a substance present in IF-containing materials. Whether a gastric glycoprotein similar to IF serves as an intestinal transport factor for heme, similar to transport of vitamin B(12), or whether normal gastric juice acts by another mechanism cannot be determined at this time.

Position statement on the role of health care assistants who are involved in direct patient care activities within critical care areas.

Intensive care has developed as a speciality since the 1950s, and during this time, there have been major technological advances in health care provision, leading to a rapid expansion of all areas of critical care. The ongoing problem in recruiting qualified nurses in general has affected, and continues to be a problem for, all aspects of critical care areas. During the past decade, nursing practice has evolved, as qualified nurses have expanded their own scope of practice to develop a more responsive approach to the complex care needs of the critically ill patient. The aim of this paper is to present the British Association of Critical Care Nurses (BACCN) position statement on the role of health care assistants involved in direct patient care activities, and to address some of the key work used to inform the development of the position statement.

Taking benefits for granted. Community benefits and market-driven health care.

No one used to question the value of hospitals to their communities. Hospitals simply took good care of the residents of the cities in which they were located. They did the little things that endear an institution to its neighbors. Perhaps this was a luxury of hardier economic times, when the pressure to control health care costs was not so pronounced. Perhaps everyone took for granted the many benefits hospitals provide for communities.
