RESUMO

INTRODUCTION AND HYPOTHESIS: The benefits of peer support for pelvic floor disorders are unclear. We hypothesize that perioperative peer support might be associated with greater preoperative preparedness compared with usual care in women undergoing pelvic reconstruction. METHODS: A multicenter prospective cohort study of women undergoing pelvic reconstruction compared peer support (group or one-to-one) with usual care. The primary outcome was preparedness, measured by a Preoperative Preparedness Questionnaire at baseline and before surgery. Assuming 48% preparedness in usual care preoperatively, 44 women per group (Group, One-to-One, or Usual care) would detect a 30% difference in preparedness (alpha = 0.05, 80% power). Chi-squared or Fisher's exact test compared categorical variables, t test and analysis of variance compared continuous variables, independent sample tests compared changes in mean or composite scores, and multiple logistic regression estimated the effect. RESULTS: One hundred and sixty-eight patients were included (113 with peer support, 55 undergoing usual care). A greater proportion of women in peer support had college or higher education versus usual care (78 vs 58%, P = 0.02). After the intervention, the proportion of women feeling prepared was not different between groups (66 vs 63%, P = 0.9). However, a greater proportion in peer support reported improved preparedness from baseline compared with usual care (71 vs 44%, P = 0.001). Peer support was associated with improved preparedness on multiple regression adjusting for age, study site, education, and surgery type (OR 4.14, 95% CI 1.69, 10.14). CONCLUSION: Peer support was associated with improved preoperative preparedness compared with usual care, but did not result in a greater proportion of women feeling prepared before surgery.

RESUMO

The immediate physical and chemical surroundings of cells provide important biochemical cues for their behavior. Designing and tailoring biomaterials for controlled cell signaling and extracellular matrix (ECM) can be difficult due to the complexity of the cell-surface relationship. To address this issue, our research has led to the development of a polydimethylsiloxane (PDMS) scaffold with defined microtopography and chemistry for surface driven ECM assembly. When human fibroblasts were cultured on this microtextured PDMS with 2-6 µm wide vertical features, significant changes in morphology, adhesion, actin cytoskeleton, and fibronectin generation were noted when compared with cells cultured on unmodified PDMS. Investigation of cellular response and behavior was performed with atomic force microscopy in conjunction with fluorescent labeling of focal adhesion cites and fibronectin in the ECM. Changes in the surface topography induced lower adhesion, an altered actin cytoskeleton, and compacted units of fibronectin similar to that observed in vivo. Overall, these findings provide critical information of cell-surface interactions with a microtextured, polymer substrate that can be used in the field of tissue engineering for controlling cellular ECM interactions.
