RNAM EXPRESSION AND DNA METHYLATION OF DKK2 GENE IN COLORECTAL CÂNCER.

Background: Colorectal cancer is the third most common neoplasm in the world. Methylation of tumor related genes in CpG islands can cause gene silencing and been involved in the development of cancer. The potential role of DKK2 as a biomarker for early diagnosis of colorectal cancer remains unclear.

Health systems: changes in hospital efficiency and profitability.

This study investigates potential changes in hospital performance after health system entry, while differentiating between hospital technical and cost efficiency and hospital profitability. In the first stage we obtained (bootstrapped) data envelopment analysis (DEA) efficiency scores. Then, genetic matching is used as a novel matching procedure in this context along with a difference-in-difference approach within a panel regression framework.

Cooperation for a competitive position: The impact of hospital cooperation behavior on organizational performance.

Background: Several public policy initiatives, particularly those involving managed care, aim to enhance cooperation between partners in the health care sector because it is expected that such cooperation will reduce costs and generate additional revenue. However, empirical evidence regarding the effects of cooperation on hospital performance is scarce, particularly with respect to creating a comprehensive measure of cooperation behavior.

Purpose: The aim of this study is to investigate the impact of hospital cooperation behavior on organizational performance.

Extending Miles & Snow's strategy choice typology to the German hospital sector.

Hospitals' strategy choices represent highly relevant factors that affect organizational performance and survival. This study assesses the differences among hospitals' strategic choices. This strategy definition and assessment reflects the typology proposed by Miles and Snow, who distinguish four strategy types: defender, analyzer, prospector, and reactor.

Who chooses, who uses, who rates: the impact of agency on electronic word-of-mouth about hospitals stays.

Background: Patients' agents rather than patients themselves often choose hospitals and rehabilitation centers and evaluate inpatient stays. Thus, online reviews of a hospital may reflect a service experience the patient is not responsible for in two ways. First, a patient may evaluate a hospital that a physician as agent has selected, although he still received the service and is qualified to evaluate it.
