How to evaluate perfusion imaging in post-treatment glioma: a comparison of three different analysis methods.

Introduction: Dynamic susceptibility contrast (DSC) perfusion weighted (PW)-MRI can aid in differentiating treatment related abnormalities (TRA) from tumor progression (TP) in post-treatment glioma patients. Common methods, like the 'hot spot', or visual approach suffer from oversimplification and subjectivity. Using perfusion of the complete lesion potentially offers an objective and accurate alternative.

Participatory curriculum development for health and independent living for disabled people: a qualitative study of participant experiences.

Participatory curriculum development is an approach that draws on participatory research philosophy by engaging members of intended audiences in the curriculum development process. This is a fairly new approach to curriculum development, which has seldom been applied in health promotion and, to our knowledge, has not previously been used to develop curriculum with disabled people. In this project, participatory curriculum development was used to both develop a new curriculum and revise an existing curriculum for in-person, web-based delivery.

Hopefulness and meaning in adults with disabilities' physical activity: A qualitative study.

Transitory and Enduring Disability Among Urban and Rural People.

Background: Disabilities are not evenly distributed across geography or age, yet few studies on disability have considered these factors. The purpose of this study was to explore rural-urban differences in disability rates, particularly related to gender and race, and what other rural-urban disparities help explain these differences.

Methods: Utilizing the 2008-2016 Current Population Survey (CPS), we first examined rural and urban disability trends by gender and race, estimating means and rural-urban percentage differences for men and women by race and conducting t test analysis to test group differences by age cohort (eg, comparing white, non-Hispanic, rural 15- to 24-year-old women to white, non-Hispanic, urban 15- to 24-year-old women).

Identifying error types in visual diagnostic skill assessment.

Background: Misinterpretation of medical images is an important source of diagnostic error. Errors can occur in different phases of the diagnostic process. Insight in the error types made by learners is crucial for training and giving effective feedback.

Life Starts at Home: Bathing, Exertion and Participation for People With Mobility Impairment.

Objective: To investigate the relationship between perceived exertion while bathing/dressing/grooming and associations with social-recreational activities outside the home for individuals with mobility impairment (MI).

Design: A 2-study approach was used to examine data from the American Time Use Survey (ATUS) and primary data from the Health and Home Survey (HHS). The relationship between bathing/dressing/grooming and engagement in social-recreational activities was explored, as well as the role that exertion in the bathroom may play in participation in these activities.

The Importance of Human-Computer Interaction in Radiology E-learning.

With the development of cross-sectional imaging techniques and transformation to digital reading of radiological imaging, e-learning might be a promising tool in undergraduate radiology education. In this systematic review of the literature, we evaluate the emergence of image interaction possibilities in radiology e-learning programs and evidence for effects of radiology e-learning on learning outcomes and perspectives of medical students and teachers. A systematic search in PubMed, EMBASE, Cochrane, ERIC, and PsycInfo was performed.

The don't know option in progress testing.

Formula scoring (FS) is the use of a don't know option (DKO) with subtraction of points for wrong answers. Its effect on construct validity and reliability of progress test scores, is subject of discussion. Choosing a DKO may not only be affected by knowledge level, but also by risk taking tendency, and may thus introduce construct-irrelevant variance into the knowledge measurement.
