Effects of radiation therapy on the structure and function of the pelvic floor muscles of patients with cancer in the pelvic area: a systematic review
Purpose ::: Radiation therapy (RT) is often recommended in the treatment of pelvic cancers. Following RT, a high prevalence of pelvic floor dysfunctions (urinary incontinence, dyspareunia, and fecal incontinence) is reported. However, changes in pelvic floor muscles (PFMs) after RT remain unclear. The purpose of this review was to systematically document the effects of RT on the PFM structure and function in patients with cancer in the pelvic area.
we examine motivations for, and costs/benefits of, participation in three interviews across a one-year period among women recently exposed to intimate partner abuse (IPA). Recruited from publicly accessible police reports, women were not informed that the study focused on IPA in recruiting materials or when they scheduled the first interview. Women ' s ratings on the Response to Research Participation Questionnaire (RRPQ) indicated a positive benefit-to-cost ratio across all three interviews. Negative responses to participation as well as severity of IPA and PTSD symptoms did not predict retention at the next interview. These data dem - onstrate that studies asking about IPA experiences, even when survivors do not know in advance that IPA will be the focus of study, can be implemented within a stable benefit-to-cost ratio over time.
