Our studies show that the presence of IL-4 during the response of naive Th cells causes precursors to develop into a population comprised largely of "Th2-like" effectors that secrete IL-4 and IL-5, but little IL-2 or IFN-gamma. We find that the levels of IL-4 and IL-2 determine both the level of effectors developed in response to mitogen or Ag and the(More)
BACKGROUND Cardiopulmonary bypass can be associated with vasodilatory hypotension requiring pressor support. We have previously found arginine vasopressin to be a remarkably effective pressor in a variety of vasodilatory shock states. We investigated the incidence and clinical predictors of vasodilatory shock in a general population of cardiac surgical(More)
BACKGROUND Preformed anti-HLA antibodies reacting specifically with donor lymphocytes have been associated with acute vascular rejection and early cardiac allograft failure. However, the effect of preformed anti-HLA antibodies directed against allogeneic major histocompatibility complex (MHC) class I or II antigens of a donor panel on heart transplantation(More)
BACKGROUND Stroke complicates the postoperative course in 1% to 6% of patients undergoing coronary revascularization. There has been no large scale mandatory database reporting on the incidence of stroke after coronary revascularization. METHODS A multicenter regional database from the Bureau of Health Care Research Information Services, New York State(More)
BACKGROUND Higher mortality for emergency coronary artery bypass grafting (CABG) after an acute myocardial infarction (AMI) is well established. Whether it applies to both transmural and nontransmural AMI is unclear. This information may have different therapeutic implications for each cohort of patients. METHODS A retrospective multicenter analysis of(More)
OBJECTIVE The role of complementary medicine techniques has generated increasing interest in today's society. The purpose of our study was to evaluate the effects of one technique, self-hypnosis, and its role in coronary artery bypass surgery. We hypotesize that self-hypnosis relaxation techniques will have a positive effect on the patient's mental and(More)
OBJECTIVE To study risk factors for early and late death after heart transplantation in the current era. SUMMARY BACKGROUND DATA The current cardiac transplant population differs from earlier periods in that an increasing number of sicker patients, such as those with ventricular assist device (LVAD) support, prior cardiac allotransplantation, and(More)
PURPOSE Urologists must contend with fluctuating prostate specific antigen (PSA) results from different assay platforms when deciding whether prostate biopsy is indicated. The contribution of cross-platform variation to these fluctuations is not well understood. To address this question we performed a cross-sectional study comparing 2 popular PSA assays(More)
We examined predictors of (1) compliance with yearly mammography and clinical breast examination (CBE) and (2) intention to obtain mammography and CBE within the following year. Subjects were 312 asymptomatic female hospital employees, 50 years or older, who had participated in a free worksite breast cancer screening program. Mammograms and CBEs had been(More)
Data from 384 individuals participating in a worksite skin cancer screening program were used to assess racial/ethnic differences in attitudes toward and practice of prevention and early detection of skin cancer. Caucasians and Hispanics were more likely than African Americans to report having used a sunscreen during the past year. Caucasians performed skin(More)
