Surface Guided Radiotherapy (SGRT) is a relatively new technique for positioning patients and for monitoring patient movement during treatment. SGRT is completely non-invasive since it uses visible light for determining the position of the patient surface. A reduction in daily imaging for patient setup is possible if the accuracy of SGRT is comparable to imaging.

The homophily principle that perceived similarities among people produce positive reactions is a cross-cultural, global phenomenon. The prediction that photographs depicting models similar to the target population improve health communication was tested. Three nationally-representative samples (n = 1,796) of adults who are disabled, seniors, or considered overweight/obese were selected from GfK's Knowledge Panel®.

During vacations, many individuals receive high-risk sun exposure that is associated with skin cancer. Vacationers in outdoor recreation venues (pretest n=4347; posttest n=3986) at warm-weather destination resorts in North America (n=41) were enrolled in a pair-matched, group-randomized pretest-posttest controlled quasi-experimental design in 2012-14. Print, audiovisual, and online messages based on Transportation Theory and Diffusion of Innovation Theory and promoting advanced sun protection (e.

Background: Vacationing at sunny, warm weather locations is a risk factor for excessive solar ultraviolet (UV) radiation exposure and skin cancer.

Objectives: This study examined the association of environmental variables related to UV levels with vacationers' sun protection.

Methods: Vacationers at 41 summer resorts in 17 states and 1 Canadian Province were interviewed (n=3531) and observed (N=4347) during 2012 and 2013.

The sustainability of evidence-based programs is needed to obtain long-term benefits. To assess sustainability of Go Sun Smart (GSS), an occupational skin cancer prevention program disseminated to the North American ski industry. Fifty-three of the 68 ski areas from the original dissemination trial participated in 2012 and 2013, 5 to 7 years after program distribution by enhanced or basic dissemination strategies.

Introduction: Exposure to solar ultraviolet radiation during recreation is a risk factor for skin cancer. A trial evaluated an intervention to promote advanced sun protection (sunscreen pre-application/reapplication; protective hats and clothing; use of shade) during vacations.

Materials And Methods: Adult visitors to hotels/resorts with outdoor recreation (i.

Objective: Sustainability of prevention programs is a public health goal.

Methods: The effectiveness of Go Sun Smart, an occupational skin cancer prevention program, was evaluated 5 to 7 years out from the conclusion of a controlled randomized dissemination trial that compared an enhanced versus basic dissemination strategy at 53 ski areas enrolled in the trial.

Results: Employees (n = 2940) at ski areas in the enhanced condition reported fewer sunburns but did not differ from employees in the basic condition on other sun-protection measures.

Importance: Skin cancer prevention remains a national priority. Reducing chronic UV radiation exposure for outdoor workers through sun-safety practices is an important step to help reduce the incidence of skin cancer.

Objective: To determine the presence of occupational sun-safety policies at local government organizations in a single state.

Health promotion programs that develop and implement strategies to promote sun safety practices to children have the potential to reduce skin cancer occurrence later in life. Go Sun Smart (GSS), a sun safety program for employees and guests of ski areas, was distributed to determine if an enhanced dissemination strategy was more effective than a basic dissemination strategy at reaching parents at ski and snowboard schools. On-site observations of GSS use and surveys of 909 parents/caregivers with children enrolled in ski and snowboard schools at 63 ski areas were conducted and analyzed using techniques for clustered designs.

Go Sun Smart is a theory-based health communication program designed to influence sun-protection behaviors of employees and guests at high-altitude ski areas to reduce skin cancer risk. The effects of Go Sun Smart, in a Phase IV dissemination randomized posttest-only trial, on sun-protection behaviors of ski area guests are reported. Program use was assessed by on-site observation and guest message exposure, and sun protection was measured in intercept surveys at ski areas.

Context: Outdoor workers are especially susceptible to skin cancer--the most common, but also one of the most preventable, forms of cancer. Colorado, the location of the study, has the second highest rate of skin cancer deaths in the nation.

Objective: Local government managers in Colorado-in municipalities, counties, and special districts-were surveyed to ascertain the extent to which they engage in formal (written) and informal practices to protect their outdoor workers against excessive exposure to sun.

A successful occupational sun-protection program was translated to 67 ski areas where the effectiveness of two dissemination strategies was assessed. An industry professional association distributed materials to the resorts. Half of the resorts received the basic dissemination strategy (BDS) in which the materials were simply distributed to the resorts.

A large and growing literature confirms that well-designed web-based programs can be effective in preventing or treating several chronic diseases. This study examined how the Internet can deliver information and train community activists and specifically tested the effects of web-based technical assistance on local tobacco control coalitions' efforts to use media advocacy to advance their agendas. The authors compared a highly interactive, Enhanced website (intervention) to a noninteractive, Basic text-based website (comparison) in Colorado communities.
