As of 2003, approximately 67% of US adults have Internet access. The purpose of this study was to determine the feasibility and preliminary efficacy of an Internet-based dyspnea self-management program (iDSMP) for people with chronic obstructive pulmonary disease. A related aim was to compare the differential effects of the iDSMP on 2 different groups: (1) to test a "booster" effect and (2) to evaluate the program as a primary intervention. ⋯ The findings suggest that additional investigations of Internet-based interventions to promote self-management in patients with chronic obstructive pulmonary disease are warranted.

Prosthetic valves have been used extensively for severe cardiac valvular dysfunction for the past 3 decades. Prosthetic cardiac valves may be infected with organisms causing bacteremia, particularly gram-positive cocci. Staphylococcus epidermidis (coagulase negative staphylococci) and Staphylococcus aureus , both methicillin-susceptible S. aureus and methicillin-resistant S. aureus (MRSA) strains, are the most frequent pathogens causing prosthetic valve endocarditis (PVE). ⋯ The cure of PVE and perivalvular abscesses usually requires removal of the prosthetic device and abscess drainage. In this case, in which surgery was not an option, medical therapy of PVE and a decrease in size of the aortic perivalvular abscess were accomplished with daptomycin therapy. Daptomycin is an alternative to vancomycin therapy in patients with prolonged or persistent MRSA bacteremia secondary to endocarditis or abscess.

The aim of this study was to describe Medical Intensive Care Unit (MICU) nurses' coping behaviors while caring for a patient whose medical treatment transitioned from cure- to comfort-oriented care. ⋯ MICU nurses are dynamic and resourceful when responding to challenging end-of-life patient care situations.
