Language barriers appear to increase the risks to patient safety. It is important for patients with language barriers to have ready access to competent language services. Providers need to collect reliable language data at the patient point of entry and document the language services provided during the patient-provider encounter.
The pH in the upper gastrointestinal tract of young, healthy men and women was measured in the fasting state and after administration of a standard solid and liquid meal. Calibrated Heidelberg capsules were used to record the pH continuously over the study period of approximately 6 hr. In the fasted state, the median gastric pH was 1.7 and the median duodenal pH was 6.1. When the meal was administered the gastric pH climbed briefly to a median peak value of 6.7, then declined gradually back to the fasted state value over a period of less than 2 hr. In contrast to the pH behavior in the stomach, feeding a meal caused a reduction in the median duodenal pH to 5.4. In addition, there was considerable fluctuation in the postprandial duodenal pH on an intrasubject basis. The pH in the duodenum did not return to fasted state values within the 4-hr postprandial observation period. There was no tendency for the duodenal pH to be related to the gastric pH in either the fed or fasted phases of the study. Furthermore, pH in the upper GI tract of young, healthy subjects appears to be independent of gender. The differences in upper GI pH between the fasted and the fed state are discussed in terms of dosage form performance and absorption for orally administered drugs.
Over a two-year period, we observed consistent improvement in measures reflecting the process of care for acute myocardial infarction, heart failure, and pneumonia. Both quantitative and qualitative research are needed to explore the reasons for these improvements.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
