Endotracheal intubation increases the risk for microaspiration of secretions around the tube cuff. Pepsin has been used as a biomarker for gastric aspiration. Amylase is a newer proposed biomarker for aspiration of oral contents. ⋯ Many patients had pepsin, amylase, or both in tracheal aspirates. Pepsin was more commonly detected than was amylase. Although the relationship of this finding to long-term outcomes was not assessed, findings indicate that microaspiration of oral and gastric secretions occurs frequently.

Policies of flexible and open visiting in intensive care units benefit both patients and patients' families. In Greek intensive care units, gaps exist between evidence and practice for family visitation, resulting in restricted visiting policies. ⋯ Nurses' beliefs about and attitudes toward visitation are important factors in the implementation of more flexible visiting policies in Greek intensive care units. Well-staffed units with experienced nurses and fewer shifts per week may affect nurses' negative attitude toward open visitation.

Oral health is integrally linked to overall well-being. This article describes a research program focused on the contribution of poor oral health to systemic illness. Initial investigations examined factors related to streptococcal virulence that were important in dental caries and endocarditis and led to development of immunization strategies in animal models to reduce risk of endocarditis. ⋯ Currently a large randomized clinical trial is being launched to determine the optimal frequency of toothbrushing for critically ill patients receiving mechanical ventilation in an effort to maximize oral health benefits while minimizing systemic risks. The importance of collaboration and mentoring in building nursing science is discussed. Future directions for research also are explored.
