BACKGROUND Recent data suggest that during mechanical ventilation the lateral-horizontal patient position (in which the endotracheal tube is horizontal) decreases the risk of ventilator-associated pneumonia, compared to the recommended semi-recumbent position (in which the endotracheal tube slopes downward into the trachea). We tested the feasibility of the lateral-horizontal patient position, ...

To determine the optimal inductive sites for immunization against Helicobacter pylori infection, the protective efficacy of recombinant urease (rUre) was assessed for mice given the vaccine by either the oral (p.o.), intranasal (i.n.), or rectal route. When mice were immunized with rUre (25 microg p.o. or rectally or 10 microg i.n.) plus heat-labile toxin from Escherichia coli as the mucosal ad...

These two cases illustrate eight instances of aspiration of fine bore enteral feed. On three occasions the tube remained correctly placed and on five occasions the tube was noted to be in the oropharynx. Fine bore enteral feeding is popular in intensive care units because ofthe high patient acceptability and ease ofmanagement in conjunction with continuous feeding pumps. Severely ill patients, ...

Background: Dietary-free L -glutamate (Glu) in the stomach interacts with specific Glu receptors (T1R1/T1R3 and mGluR1–8) expressed on surface epithelial and gastric gland cells. Furthermore, luminal Glu activates the vagal afferents in the stomach through the paracrine cascade including nitric oxide and serotonin (5-HT). Aim: To elucidate the role of dietary Glu in neuroendocrine control of th...

The effects of a cow's milk diet on receptor activity and histamine metabolism in gastric glands and mucosa isolated from adult rats were examined. The milk diet was associated with (1) a decreased mobilization of H2 receptors by histamine and (2) an increased mobilization of PGE2 (prostaglandin E2) receptors in mucous cells (cytoprotective effect) and parietal cells (antiacid effect). These ch...

The presence of human immunodeficiency virus (HIV) in cervicovaginal secretions (CVS) may be a risk factor for perinatal transmission. CVS of 25 women were evaluated for HIV and HIV mucosal antibodies; 16 infants had gastric aspirates cultured. Maternal plasma HIV was measured by quantitative RNA polymerase chain reaction. Seven women (28%), 4 of 19 pregnant and 3 of 7 nonpregnant, had HIV in C...

Norma Metheny is a professor and the Dorothy A. Votsmier Endowed Chair in Nursing at Saint Louis University in St Louis, Missouri. because standard care mandates frequent position changes to prevent pressure ulcers as well as pooling of respiratory secretions. When missed calories due to position changes are added to those associated with feeding interruptions for other reasons (eg, preparation...

The relationship between the intragastric distribution, dilution, and emptying of meals and satiety was studied using noninvasive magnetic resonance imaging techniques in 12 healthy subjects with four polysaccharide test meals of varying viscosity and nutrient content as follows: 1) low-viscosity nonnutrient, 2) low-viscosity nutrient, 3) high-viscosity nonnutrient, and 4) high-viscosity nutrie...
