Quantifying Worry in the Face of Uncertainty: Radiation Exposure from Medical Imaging.

Background: The degree to which people worry about radiation exposure from medical imaging has not been quantified. Such concern is important for clinical decision making and policy generation.

Objective: The aim of this study was to quantify the degree of worry as a consequence of radiation exposure.

Health care worker exposures to the antibacterial agent triclosan.

Objective: We sought to quantify absorption of triclosan, a potential endocrine disruptor, in health care workers with occupational exposure to soap containing this chemical.

Methods: A cross-sectional convenience sample of two groups of 38 health care workers at separate inpatient medical centers: hospital 1 uses 0.3% triclosan soap in all patient care areas; hospital 2 does not use triclosan-containing products.

The risk of potential thromboembolic, renal and cardiac complications of sickle cell trait.

Many complications of sickle cell trait have been well-established, but associations with additional disease states remain controversial. We conducted a retrospective cohort study to examine the frequency of receiving a diagnosis of thromboembolism, pulmonary embolism (PE), ischemic stroke, renal disease (acute, chronic), coronary artery disease (CAD) and congestive heart failure (CHF) in patients with sickle cell trait. A total of 13,964 adult African Americans registered in the Kaiser Permanente Northern California (KPNC) health system (Oakland, CA, USA), were included based on laboratory and diagnostic code data for the years 1995-2008: 2642 with sickle cell trait, 11,183 with normal hemoglobin (Hb) and 139 with sickle cell disease.
