In a phase I National Cancer Institute (NCI)-funded clinical trial, 34 breast cancer survivors, six weeks to one year post-treatment, were recruited to participate in a 6-class, 8-week long imagery stress reduction program entitled "Envision the Rhythms of Life." Patients practiced imagery during and between sessions. Outcomes for quality of life and cortisol rhythm were assessed pre- to post-intervention, in two subsets of survivors (intravenous [IV] chemotherapy, or no IV chemotherapy).

Objective: To compare biologically targeted imagery (BTI) and critical thinking asthma management (CTAM) outcomes.

Design: Participants were randomized to BTI (group 1, G1) or CTAM (group 2, G2) in a 2 x 2 x 4 design (BTI/CTAM x pretest/post-test x weeks [3 week averaged intervals of symptoms and peak flows]). Interventions were asthma education plus treatment (BTI or CTAM for two 2-hour sessions per week for 6 weeks).

The importance of using culturally sensitive educational materials in HIV-related interventions with racial and ethnic minority groups is widely recognized. However, little empirical research has been conducted to assess the relative effectiveness of different techniques for creating culturally sensitive AIDS educational videos. Two field experiments with three samples of African American adults (N = 174, 173, and 143) were conducted to assess how source characteristics (race of communicator), message characteristics (multicultural message vs.

Attenuation of exercise-induced increases in heart rate and cardiac output by chronic beta-adrenergic blockade has been thought to compromise benefit of exercise training in patients with coronary artery disease (CAD). To assess this important issue, 35 CAD patients were evaluated by a 3-month walk-jog-cycle training program: 14 patients received no beta blocker (group 1), 14 received propranolol, 30-80 mg/day (group 2), and seven patients received propranolol, 120-240 mg/day (group 3). The extent of CAD, resting heart rate before training blood pressure and VO2 max were similar (p = NS) in each group.

To determine the effects of exercise training on left ventricular performance and myocardial perfusion in coronary artery disease, rest and exercise radionuclide angiocardiography and thallium-201 scintigraphy were performed before and after 12 weeks of training in 16 coronary patients. After training, 15 of the 16 patients had improved exercise tolerance; total treadmill exercise duration increased from (mean +/- standard error of the mean) 491 +/- 37 to 602 +/- 31 seconds (p less than 0.01), and the estimated rate of oxygen consumption (VO2 max) increased from 29.

Multiple episodes of documented recurrent infective endocarditis occurred in an habitual drug abuser. The six recurrences represent the largest known number reported in a single patient. The case illustrates many characteristics of infective endocarditis and serves to emphasize that recurrent infections are likely if endocarditis risk factors are not eliminated.

Controversy persists concerning the role of early surgical intervention in severe infective endocarditis (IE). We therefore reviewed 163 episodes of well-documented IE in which 32 cardiac operations were performed during the active phase of IE. Congestive heart failure (CHF) was the principal indication for surgery in 88% (28/32); systemic emboli, 1/32; and persisting sepsis, 3/32.
