A Phase Ii Trial Of Arc-Based Hypofractionated Intensity-Modulated Radiotherapy In Localized Prostate Cancer, Michael Lock Dec 2010

A Phase Ii Trial Of Arc-Based Hypofractionated Intensity-Modulated Radiotherapy In Localized Prostate Cancer, Michael Lock

Michael Lock

Abstract PURPOSE: To evaluate acute and late genitourinary (GU) and gastrointestinal (GI) toxicity and biochemical control of hypofractionated, image-guided (fiducial markers or ultrasound guidance), simplified intensity-modulated arc therapy for localized prostate cancer. METHODS AND MATERIALS: This Phase II prospective clinical trial for T1a-2cNXM0 prostate cancer enrolled 66 patients who received 63.2 Gy in 20 fractions over 4 weeks. Fiducial markers were used for image guidance in 30 patients and daily ultrasound for the remainder. Toxicity was scored according to the National Cancer Institute Common Terminology Criteria for Adverse Events version 3.0. RESULTS: Median follow-up was 36 months. Acute Phase Grade …

Bucindolol: A Pharmacogenomic Perspective On Its Use In Chronic Heart Failure, Neil Smart Dec 2010

Bucindolol: A Pharmacogenomic Perspective On Its Use In Chronic Heart Failure, Neil Smart

Neil Smart

Bucindolol is a non-selective ß-adrenergic receptor blocker with a-1 blocker properties and mild intrinsic sympatholytic activity. The Beta-Blocker Evaluation of Survival Trial (BEST), which is the largest clinical trial of bucindolol in patients with heart failure, was terminated prematurely and failed to show an overall mortality benefit. However, benefits on cardiac mortality and re-hospitalization rates were observed in the BEST trial. Bucindolol has not shown benefits in African Americans, those with significantly low ejection fraction and those in NYHA class IV heart failure. These observations could be due to the exaggerated sympatholytic response to bucindolol in these sub-groups that may …

OBJECTIVES:
To determine the impact of time between initiating highly active antiretroviral therapy (HAART) and delivery-duration of antenatal HAART-on perinatal HIV infection.
DESIGN:
We conducted a retrospective cohort analysis of pregnant HIV-infected women in Lusaka, Zambia. Women in our cohort were receiving HAART and had an infant HIV polymerase chain reaction test between 3 and 12 weeks of life.
METHODS:
We examined factors associated with infant HIV infection and performed a locally weighted regression analysis to examine the effect of duration of antenatal HAART on perinatal HIV infection.
RESULTS:
From January 2007 to March 2010, 1813 HIV-infected pregnant women met …
