NCT06690801
The goal of this observational study is to determine whether a marker of dead space (the end-tidal to alveolar dead space fraction \[AVDSf\]) is more strongly associated with mortality risk than markers of oxygenation abnormality (oxygenation index) and to determine whether dead space (AVDSf) is an important marker of heterogeneity in the inhaled nitric oxide (iNO) treatment effect for children with acute respiratory distress syndrome (ARDS). The study aims are: 1. To validate AVDSf for risk stratification of mortality in pediatric ARDS 2. To determine if there is heterogeneity in treatment effect for iNO defined by AVDSf 3. To detect the association between AVDSf and microvascular dysfunction trajectory and whether iNO therapy modifies this association This is a prospective, multicenter observational study of 1260 mechanically ventilated children with moderate to severe ARDS. In a subgroup of 450 children with severe ARDS, longitudinal blood samples will be obtained to measure plasma protein markers.

This study is open to people aged 18 to 65 who have post-traumatic stress disorder. The purpose of this study is to find out whether a medicine called BI 1358894 improves symptoms in people with post-traumatic stress disorder. Participants are put into 2 groups randomly, which means by chance. Participants take BI 1358894 or placebo as tablets every day for 2 months. Placebo tablets look like BI 1358894 tablets but do not contain any medicine. Participants are in the study for about 3 months. During this time, they visit the study site about 8 times and get about 4 phone calls from the trial staff. During the study, participants answer questions in interviews and complete questionnaires so the doctors can check whether their symptoms change. The doctors also regularly check participants' health and take note of any unwanted effects.
