Think-Aloud Testing of a Companion App for Colonoscopy Exams: Usability Study.

Background: Colonoscopies, are vital for initial screening, follow-ups, surveillance of neoplasia, and assessing symptoms like rectal bleeding. Successful colonoscopies require thorough colon preparation, but up to 25% fail due to poor preparation. This can lead to longer procedures, repeat colonoscopies, inconvenience, poorer health outcomes, and higher costs.

The Pierced Colon: When Biliary Stents Go the Wrong Way.

Bowel perforation of biliary stents is a rare complication of biliary stenting. We report the successful endoscopic treatment of a 78-year-old man with a straight biliary plastic stent perforating the ascending colon without underlying structural abnormality in the affected segment. Perforation was detected incidentally during computed tomography; the patient had been under continued antibiotic therapy for liver abscess.

Prevalence and risk factors for post-traumatic stress disorder in relatives of out-of-hospital cardiac arrest patients.

Aim: Prognostic uncertainty and surrogate decision-making demands associated with prolonged unconsciousness in out-of hospital cardiac arrest (OHCA) patients in the intensive care unit (ICU) may increase post-traumatic stress disorder (PTSD) risk in their relatives. Our aim was to study PTSD frequency and risk factors in relatives of OHCA patients.

Methods: In this observational study 101 consecutive eligible adult relatives of OHCA patients were interviewed using validated questionnaires, the "Impact of Event Scale-Revised" to detect PTSD and the "Family-Satisfaction with Care in the ICU" to assess potential PTSD risk factors.
