Positive cognitive reappraisal flexibility is associated with lower levels of perceived stress.

This study investigates the role of positive cognitive reappraisal (PCR) flexibility and variability in mental health in response to real-life stressors among college students. We employed ecological momentary assessment and intervention through ReApp, a mobile app designed to train and promote PCR. We analyzed data from the intervention group of a randomized controlled trial with a total of 100 participants who used ReApp for three weeks.

Prolonged heterogeneous liver enhancement on contrast-enhanced ultrasound.

Introduction: Prolonged heterogeneous liver enhancement (PHLE) is a rare phenomenon that is similar to the ultrasound findings of portal venous gas. The purpose of this report is to describe the phenomenon of PHLE after the injection of the ultrasound contrast agent SonoVue(®).

Patients And Methods: From 2000 to 2013, 13 patients with PHLE ("cloudy", "wool-like") after bolus injection of SonoVue(®) were observed.

Study of skin-fabric interactions of relevance to decubitus: friction and contact-pressure measurements.

Background/purpose: Prolonged pressure as well as friction and shear forces at the skin-textile interface are decisive physical parameters in the development of decubitus. The present article describes the contact phenomena at the skin-textile interface and the development of a purpose-built textile friction analyser (TFA) for the tribological assessment of skin-fabric interactions, in connection with decubitus prevention.

Methods: Interface pressure distributions were recorded in the pelvic and femoral regions between supine persons and a foam mattress.

[Value of gynecologic sonography within the scope of preoperative diagnosis. I. Retrospective evaluation of clinically and sonographically suspected diagnoses in 1,168 patients].

In 1168 women patients operated on between January 1981 and July 1984 at the Department of Gynaecology of the University of Tübingen it was possible to control retrospectively the suspected diagnoses that had been made preoperatively, both clinically as well as sonographically, the control being based on an examination of the site of operation and/or the histological preparation. Sonographic examination was mostly effected after clinical examination while being aware of the clinically suspected diagnosis. Preoperative clinical diagnosis was found to be mostly correct in 816 patients (69.
