Patient with systemic emboli in the setting of tricuspid valve endocarditis and patent foramen ovale treated with NobleStitch and AngioVac.

A 34-year-old man with a medical history of injection drug use presented with 2 weeks of weakness, nausea, vomiting and septic shock secondary to infective endocarditis of a native tricuspid valve. On admission, CT chest demonstrated multiple cavitary lesions as well as numerous small infarcts seen on MRI brain concerning for systemic septic emboli. Subsequent transthoracic echo with bubble study revealed a large patent foramen ovale (PFO).

Confidentiality and the psychological treatment of U.S. Army aircrew members.

The present article addresses the issue of confidentiality in U.S. Army psychological services and the special considerations affecting the confidentiality afforded to Army aviation personnel receiving such services.

Ventilatory threshold and work efficiency during exercise on a cycle and rowing ergometer.

The purpose of this investigation was to determine the effects of increasing specific (rowing ergometer) and non-specific (cycle ergometer) workloads on parameters relating to the ventilatory threshold (Tvent) and work efficiency. When highly trained male rowers were tested using non-specific workloads, their %VO2 max values at Tvent were close to those characteristic of untrained subjects (74.6 +/- 6.

Kinetics of heart rate responses to exercise.

In order to describe the kinetics of the reaction of the heart rate (HR) to the onset of exercise of constant intensity, the half-time (t1/2) of HR can be used. First in a study of exercise of intensity corresponding to 2 W kg-1 on a cycle ergometer, the t1/2 in 15 trained male rowers and 11 untrained male students was determined. In the trained subjects t1/2 was smaller than in untrained students, mean (+/- S.
