The purpose of the study was the evaluation of the effect of a treatment for highly-active relapsing multiple sclerosis (RMS). This was the extension study to CLARIFY MS (NCT03369665), to assess cognitive impairment and health related quality of life (HRQoL) in participants with highly active RMS, at 4 years after initial dose of Mavenclad® tablets.
Higher aerobic capacity before surgery, as indicated during submaximal exercise testing by the oxygen uptake (VO2) at the ventilatory anaerobic threshold (VAT), is assumed to be prognostic for a better and faster postoperative recovery in patients with knee osteoarthritis (OA) undergoing total knee arthroplasty (TKA). Cardiopulmonary exercise testing (CPET) is the gold standard to measure aerobic capacity; however, it is unclear whether it is feasible to perform CPET using cycle ergometry in patients with knee OA prior to TKA surgery. The hypothesis is that performing CPET is feasible and participants will meet the feasibility criteria for success. The primary objective of this cross-sectional feasibility study is to investigate the feasibility of CPET in patients with knee OA three to six weeks prior to TKA surgery in three domains: a) recruitment rate of participants who are representative of the target study population; b) reaching the VAT during CPET; and c) acceptability and suitability. The secondary objective is to investigate aerobic capacity of the study population and to compare values with normative values. The study population consists of patients with knee OA scheduled for primary unilateral TKA surgery. Feasibility of CPET will be assessed against five criteria: 1) recruitment rate ≥20%; 2) CPET performance rate ≥90%; 3) ≥90% of participants reached the VAT; 4) no serious adverse events; and 5) ≥80% of participants had a positive attitude towards CPET. Aerobic capacity is determined by the VO2 at the VAT and the oxygen uptake efficiency slope (OUES). CPET is considered a safe procedure. Participants perform the CPET instead of a walking test following the standard preoperative screening and complete a questionnaire to examine their experiences. The investigator will contact the participants one week after the CPET to inquire whether they have developed any complaints afterwards. Benefit from participation is that all patients objectively get insight in their preoperative aerobic capacity.

This study is open for men and women with a liver disease called nonalcoholic steatohepatitis (NASH) and liver fibrosis. The purpose of the study is to find out whether a medicine called BI 456906 helps patients with NASH and liver fibrosis. The study tests 3 different doses of BI 456906 to find the dose that helps best. Participants are put into 4 groups randomly, which means by chance. There are 3 groups that each receive a different dose of BI 456906 and there is 1 group that receives placebo. BI 456906 and placebo are given as an injection under the skin once per week. The placebo injection looks like the BI 456906 injection but does not contain any medicine. Participants are in the study for a little over 1 year (60 weeks). During this time, they visit the study site several times and have some video calls in addition. At the visits, the study doctors take different measurements. To see whether the treatment works, the doctors take a very small sample of liver tissue (biopsy) from each participant at the start and at the end of the study. They also examine the liver by ultrasound and MRI. The doctors also regularly check the general health of the participants.
Coronavirus disease 2019 (COVID-19) is caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). While the majority of people recover after mild symptoms, a portion of COVID-19 patients develops respiratory failure. Coagulopathy and thromboembolism are prevalent in severe COVID-19, and these factors are associated with decreased survival. Coagulation is an intricate balance between clot promoting and dissolving processes in which vitamin K plays an essential role. Elastin is a major component of dynamic tissues such as lungs and arteries, and elastin calcification stimulates elastin degradation and vice versa. The vitamin K-dependent Matrix Gla Protein (MGP) protects elastin from both calcification and degradation. Although technically feasible, direct quantification of blood vitamin K levels is not an appropriate method to assess overall vitamin K status due to differences in bioavailability and half-life time between the two naturally occurring vitamin K forms (vitamin K1 and K2). Measuring inactive levels of vitamin K-dependent proteins in the circulation is the method recommended by most experts, as it represents the systemic availability of both vitamin K1 and K2. Dp-uc (dephospho uncarboxylated, i.e. inactive) MGP and proteins induced by vitamin K absence (PIVKA-II) both inversely correlate with vitamin K status and can be used as surrogate markers of total vitamin K status. Recently, we found a severely reduced vitamin K status (as quantified by dp-ucMGP) in COVID-19 patients compared to controls. In COVID-19 patients, low vitamin K status was also associated with poor outcome (defined as the need for invasive ventilation or death), accelerated elastin degradation (quantified by plasma (iso)desmosine (DES) a byproduct of elastin degradation). Based on these finding and previous studies, we hypothesize that improving vitamin K-status by vitamin K supplementation could have favorable effects on pulmonary damage and coagulopathy in COVID-19.

Rationale: Dual antiplatelet therapy, consisting of aspirin and a P2Y12-inhibitor, reduces the risk of stent thrombosis, myocardial infarction and stroke after coronary stent implantation. Inevitably, it is also associated with a higher risk of (major) bleeding. Given the advances in stent properties, stenting implantation technique and pharmacology, it may be possible to treat patients with a single antiplatelet strategy using a potent P2Y12-inhibitor such as prasugrel or ticagrelor. Objective: This study will serve as a pilot to investigate the feasibility and safety of a single antiplatelet strategy with prasugrel or ticagrelor prior to, during and after stent implantation in 75 patients with non-ST segment elevation acute coronary syndrome. Study design: Single-center, single arm pilot study with a stopping rule based on the occurrence of definite stent thrombosis. Study population: Patients presenting with non-ST segment elevation acute coronary syndrome and (a) 'de novo' lesion(s) treated with new generation drug-eluting stent(s) with adequate reduction of platelet reactivity according to platelet function testing with VerifyNow and optimal stenting result adjudicated by optical coherence tomography or coronary angiography. Intervention: Once daily 10 mg prasugrel or twice daily 90 mg ticagrelor for 12 months preceded by a loading dose of 60 mg prasugrel or 180 mg ticagrelor at least 2 hours prior to percutaneous coronary intervention without concurrent aspirin therapy. Main study endpoint: The primary ischemic endpoints is the composite of all-cause mortality, myocardial infarction, Academic Research Consortium defined stent thrombosis and ischemic stroke at 6 months after percutaneous coronary intervention. The primary bleeding outcome is major or minor bleeding defined as Bleeding Academic Research Consortium type 2, 3 or 5 bleeding at 6 months after percutaneous coronary intervention.
This is a prospective, multi-center, non-invasive, interventional, data collection study to improve the current BIS algorithm in the elderly adult population.
Nocebo effects, negative responses to inert or active treatments which are putatively induced by negative outcome expectations, have been shown to play a significant role in pain perception. The underlying neurobiological mechanisms of these effects remain largely unexplored. The primary objective of this study is to test the role of N-methyl-D-aspartate (NMDA) receptor-dependent learning in an experimental model of conditioned nocebo effects on self-reported pain. Secondary objectives are to examine the role of the NMDA manipulation and related neural correlates during the acquisition and extinction of nocebo effects using statistical learning models. This study will utilize a placebo controlled, double-blind design with respect to the pharmacological administration of 80 mg D-Cycloserine (DCS), an NMDA agonist, or placebo. Validated conditioning and verbal suggestion (VS) paradigms will induce nocebo effects on pain in a random sample of 50 healthy adults. The primary endpoint of the study is the magnitude of the induced nocebo effect on pain measured as the difference between self-reported pain, between the first conditioned and control extinction trials. Secondary endpoints include the classification analysis of the Blood Oxygen Level Dependent (BOLD) responses of participants into pharmacological groups with multivariate pattern analysis. This study will be conducted at Leiden University and the Leiden University Medical Center (LUMC), The Netherlands.
