Purpose: Recommended surveillance for BRCA1 and BRCA2 mutation carriers includes regular mammography and clinical breast examination, although the effectiveness of these screening techniques in mutation carriers has not been established. The purpose of the present study was to compare breast magnetic resonance imaging (MRI) with ultrasound, mammography, and physical examination in women at high...

BACKGROUND Recruiting workers in small construction companies and securing their participation in voluntary safety programs or safety research poses unique challenges. Worker turnover and worksite changes contribute to difficulties in locating and enrolling participants. Economic pressures and time demands potentially threaten ongoing participation. METHODS Six simulation exercises designed t...

This chapter reviews the literature devoted to studying markets for health care services and health insurance. There has been tremendous growth and progress in this field. A tremendous amount of new research has been done since the publication of the first volume of this Handbook. In addition, there has been increasing development and use of frontier industrial organization methods. We begin by...

Physical and mechanical properties of the drug-incorporated polymer play a significant role in release behavior from drug carriers. Understanding relative extent variation physical makes it possible to improve design carriers obtain better profile increase stability. Drug delivery PLGA loaded with various percentages diclofenac sodium (DS: 0, 5%, 10%) at different flow rates 0 7.5 ml/s (flow ra...

Drug delivery research areas is continuously broaden and modified as a results of the realization of many factors (such as poor drug solubility and/or absorption, rapid metabolism, high fluctuation in the drug plasma level and variability) adversely affect in-vivo results, in conventional drug delivery system. Lipids are one of the basic building blocks of biological membranes. Nanoscale-based ...

Photoluminescence (PL) identifies spectroscopic signatures of intertube transfer of optically pumped carriers in single-walled carbon nanotube (SWNT) ensembles. Resonant photoexcitation of large band gap SWNTs produces strong PL from smaller band gap SWNTs. Magnetic alignment measurements associate the energy-transfer PL peaks with the formation of SWNT bundles, suggesting that efficient coupli...

The focus of this paper is on the trade-off between cost efficiency and access in the choice of the optimal mix of public and private provision in universal health systems. We model a simple health care market in which the regulator acts as a third payer. Patients need one unit of medical service and differ in the severity of illness. A private and a public hospital are available. The private m...

In response to rising health care costs associated with obesity rates, some health care insurers are adopting incentivized technology-enhanced wellness programs. The purpose of this study is to evaluate the large-scale implementation of an incentivized Internet-mediated walking program for obese adults and to examine program acceptance, adherence, and impact. A mixed-methods evaluation was cond...

We retrospectively analysed 219 consecutive treatment plans submitted to a large New South Wales workers' compensation insurer for workers coded by the insurer as suffering from back pain. The purpose was to (i) describe the quality of goals of treatment provided to insurers by physiotherapists for workers with back pain using guidelines provided by the WorkCover Authority of New South Wales (W...
