The Health Information National Trends Survey data portray a tectonic shift in the ways in which patients consume health and medical information, with more patients looking for information online before talking with their physicians.

Little is known about access, sources, and trust of cancer-related information, or factors that facilitate or hinder communication on a population-wide basis. Through a careful developmental process involving extensive input from many individuals and organizations, the National Cancer Institute (NCI) developed the Health Information National Trends Survey (HINTS) to help fill this gap. This nationally representative telephone survey of 6,369 persons aged > or = 18 years among the general population was first conducted in 2002-2003, and will be repeated biennially depending on availability of funding. The purpose of creating a population survey to be repeated on a cyclical basis is to track trends in the public's rapidly changing use of new communication technologies while charting progress in meeting health communication goals in terms of the public's knowledge, attitudes, and behaviors. The HINTS survey instrument was built upon extant models of health communication and behavior change, taking into account the rapidly changing communication environment. Questions in the survey were drawn from an overall theoretical framework that juxtaposed the"push" aspects of traditional broadcast media against the"pull" aspects of new media. HINTS data will be made widely available for researchers and practitioners; it will help further research in health communication and health promotion and provide useful information for programs, policies, and practices in a variety of settings.

The conceptional design of the proposed linear electron-positron collider TESLA is based on 9-cell 1.3 GHz superconducting niobium cavities with an accelerating gradient of E acc $ 25 MV͞m at a quality factor Q 0 $ 5 3 10 9 . The design goal for the cavities of the TESLA Test Facility (TTF) linac was set to the more moderate value of E acc $ 15 MV͞m. In a first series of 27 industrially produced TTF cavities the average gradient at Q 0 5 3 10 9 was measured to be 20.1 6 6.2 MV͞m, excluding a few cavities suffering from serious fabrication or material defects. In the second production of 24 TTF cavities, additional quality control measures were introduced, in particular, an eddy-current scan to eliminate niobium sheets with foreign material inclusions and stringent prescriptions for carrying out the electronbeam welds. The average gradient of these cavities at Q 0 5 3 10 9 amounts to 25.0 6 3.2 MV͞m with the exception of one cavity suffering from a weld defect. Hence only a moderate improvement in production and preparation techniques will be needed to meet the ambitious TESLA goal with an adequate safety margin. In this paper we present a detailed description of the design, fabrication, and preparation of the TESLA Test Facility cavities and their associated components and report on cavity performance in test cryostats and with electron beam in the TTF linac. The ongoing research and development towards higher gradients is briefly addressed.

There is substantial epidemiological evidence that widespread adoption of specific behavior changes can significantly improve population health. Yet, health communication efforts, while well intentioned, have often failed to engage people to change behavior within the complex contexts of their lives. `E-health communication', health promotion efforts that are mediated by computers and other digital technologies, may have great potential to promote desired behavior changes through unique features such as mass customization, interactivity and convenience. There is growing initial evidence that e-health communication can improve behavioral outcomes. However, we have much to learn about whether the technical promise of e-health communication will be effective within the social reality of how diverse people communicate and change in the modern world. This article examines current evidence concerning e-health communication and evaluates opportunities for e-health applications.

Objective-To examine the cancer information seeking behaviors and preferences of cancer survivors. Results-Two thirds (67.5%, n=418) of the survivors sought cancer information (InfoSeek) and 32.5% (n=201) did not (NoInfoSeek). Significant predictors of cancer information seeking included age (less than 65), gender (female), income (>$25,000/yr) and having a regular HCP. Methods-ThisConclusion-Not all survivors actively look for cancer information. Although most survivors prefer receiving cancer information from their HCP, many turn to a variety of other sources, primarily the internet.Practice Implications-HCPs should periodically assess information seeking behaviors and preferences of cancer survivors and actively refer patients to the Internet as an extension of and enhancement to their patient interactions. Credible and useful websites could be identified and recommended by the HCP as a means to address some of the barriers identified by survivors.
