- Given a conePof positive functions and an operatorS: →Pwith an additive group, we extend the concept ofK-divisibility to get some new formulas for theK-functional of finite families of lattices. Applications are given in the setting of rearrangement invariant spaces and weighted Lorentz spaces. As a consequence of our results, we also obtain a generalized Holmstedt formula due to Asekritova

Failure to demonstrate myocardial protective effects of the ultra short-acting calcium antagonist clevidipine in a closed-chest reperfusion porcine model.

- Restoration of myocardial perfusion is essential in acute myocardial infarction for the salvaging of myocardial tissue. However, reperfusion per se can provoke myocardial necrosis within the jeopardized tissue. Yet, no intervention has been successfully applied to the clinical situation in this matter. Clevidipine, an ultra-short acting calcium antagonist, has, in open-chest animal models, shown to reduce the extent of reperfusion injury. In the present study we intended to reproduce those findings in a closed-chest porcine model with a clinically applicable set up. Pigs were subjected to balloon occlusion of the left anterior descending coronary artery (LAD) for 45 minutes. During 25 minutes, starting 1 minute prior to reperfusion, clevidipine, Intralipid, or saline was infused antegradely into the endangered myocardium. As no significant effects on infarct size were achieved, the model was modified. In a second phase, different anesthesias were evaluated addressing the same issue. Nonetheless no significant effects on infarct size were observed. Different techniques of occluding LAD, in an open-chest model, were investigated in a third phase, and revealed no significant differences between the techniques. However, when comparing all the closed- versus open-chest models, significant reduction in infarct size by the use of clevidipine was only obtained in the open-chest models. We could not demonstrate any significant myocardial protective effect with clevidipine in our porcine, closed-chest, acute infarct, and reperfusion model. However, in a modified open-chest model we obtained significant reduction in infarct size. Further studies are required to explain the discrepancies.

Acceptance and Commitment Therapy for inpatients with psychosis -an acceptability and feasibility single case AB designed study
- 2022

- Background: There is a lack of research on psychological treatments for psychosis in the inpatient setting. Acceptance and Commitment Therapy for psychosis (ACTp) is a diagnose specific adaptation of the transdiagnostic ACT treatment model which has shown promising results in patients with psychosis. Aim: The aim was to explore treatment effects of ACTp on inpatients with psychosis on symptoms, level of functioning, level of activity, psychological flexibility, -health-related quality of life, valued living, and to explore the acceptability and feasibility of ACTp. Method: Twelve inpatients with psychosis were treated with 3-10 daily sessions of ACTp in a non-concurrent single case AB design with additional pre-post and mid-measures. The mean age at clinic A was 48.88 (SD = 11.59) and 48.75 (SD = 16.07) at clinic B. We calculated non - overlap of all pairs (NAP) in daily measures, and reliable change index (RCI), and clinical significance in pre-post measures. Results: Half of the participants improved significantly on health-related quality of life and depression in daily measures and on depression and anxiety in pre-post measures. ACTp was quite acceptable and recruitment and the deliverance of therapy in the inpatient setting was feasible. Conclusion: In the present study, participants found the ACTp treatment to be comprehensive and helpful. Recruitment and treatment of inpatients were feasible, however, since most participants were discharged before ACTp protocol was completed, fewer sessions or having sessions more frequently needs further investigation. Daily measurement showed a significant improvement in health-related quality of life and depression for a majority of the participants.

The vaginal pH and leucocyte/epithelial cell ratio vary during normal menstrual cycles.

- A higher proportion white blood cells (WBC) than vaginal epithelial cells in wet smears has been accepted as a sign which, together with clinical signs, can be useful in the diagnosis of infections in the genital tract such as cervicitis or salpingitis. However, little is known about the normal variation among healthy women without any symptoms or signs of genital-tract infection. By taking frequent wet smears from three healthy asymptomatic women during four menstrual cycles we found that vaginal leucocytosis usually occurred once each cycle. Normal vaginal leucocytosis must thus be taken into consideration when evaluating wet smear of patients for genital tract infections.
