Homework is often viewed as central to prolonged exposure (PE) for posttraumatic stress disorder (PTSD), but its relationship with treatment outcome is not well understood. We evaluated homework type, dose, and patients' perceptions of helpfulness as predictors of symptom change and posttreatment outcomes in PE. Patients with chronic PTSD received PE in a randomized clinical trial. Independent evaluators assessed PTSD severity at pre- and posttreatment. Patients reported homework adherence and perceived helpfulness at the beginning of each session, separately for in vivo and imaginal exposure assignments...

Electrospun fibers of natural polymers are desirable for biomedical applications such as tissue engineering. Crosslinking of electrospun fibers of natural polymers is needed to prevent dissolution in water and to enhance mechanical strength. In this study, an in situ UV-crosslinking method was developed for crosslinking of gelatin electrospun fibers (GESFs) and water-soluble synthetic polymers. A mixture of gelatin and phenylazide-conjugated poly(acrylic acids) was electrospun under UV irradiation. The UV-crosslinked GESFs were not dissolved in water with improved mechanical strength...
