There are about 6915 clinical studies being (or have been) conducted in Austria. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Epiretinal membranes are a disease of the retinal surface, that may affect visual acuity and cause metamorphopsia. Using vitrectomy with membrane peeling, postoperative improvement of visual acuity and metamorphopsia may be achieved in a majority of patients. Diaz et al. demonstrated that there are postoperative changes in the "nerve fiber layer" after ILM peeling, but in that study, no recording of instrument/tissue interactions was performed using iOCT. The aim of this study is to examine dipping into retinal tissue with the forceps during grasping of the epiretinal membrane at the starting point of peeling with iOCT.
The study involves 20 patients who require implant treatment for the edentulous lower jaw, following specific inclusion and exclusion criteria. Patients are drawn from the regular pool of those seeking implant therapy, with no additional recruitment efforts. This study compares the effects of loaded and non-loaded dental implants. Preoperative assessments include medical histories, clinical, and radiographic examinations of the jaw. Participants are thoroughly informed about the study procedures and consent to participate through signed agreements. They undergo preoperative diagnostics, including panoramic X-rays to evaluate mandibular bone height, and complete the OHIP-G 14 questionnaire to establish a baseline for their oral health-related quality of life. The implant placement involves standard outpatient surgical procedures under local anesthesia. The implants used are CE-certified and are placed in predetermined positions in the edentulous region. During the surgery intraoral scans and conventional impressions are performed. Post-operative care includes oral rinses, and radiographic assessments, with follow-up visits scheduled for suture removal and further assessments using the visual analog scale for pain and swelling. The healing phase spans four months, during which patients' comfort and oral health are monitored through clinical examinations and additional questionnaires. Follow-up after 4 months includes re-entry surgery and further radiographic evaluations and intraoral scans to assess the bone's response around the implants. Throughout the study, adverse events and patient satisfaction are continuously documented. In the later stages, regular follow-up visits for up to 24 months post-surgery to monitor implant stability and health through clinical and radiographic check-ups are performed. This study aims to document implant survival rates, peri-implant bone regeneration, assess biological and technical complications, and evaluate patient satisfaction and quality of life throughout the implant process, providing valuable data for future dental implant protocols.
Crohn's disease (CD), a chronic inflammatory disease affecting the intestine, is characterised by a relapsing course. In 25% of cases, the onset of this disease occurs in childhood. Relevant studies have provided evidence of a key role of gut microbial communities (the microbiota) in triggering or maintaining active gut inflammation, pointing to gut dysbiosis as the main event disrupting the balance of microbial communities Recent evidence suggests that, in addition to the bacterial component, the commensal fungal component also plays a crucial role in CD. The purpose of this prospective, longitudinal, study is to characterise the composition of intestinal bacterial and fungal communities in patients 6-18 years newly diagnosed with Crohn Disease in order to identify a possible association of specific faecal microbial profiles with a severe or mild-to-moderate disease course.
Temporary aortic occlusion can limit haemorrhage, can help to maintain perfusion to the heart and brain, and may be associated with improved survival. Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) potentially provides a relatively quick means of achieving this temporary control. In the past years, studies have tried to evaluate the benefit for this method with conflicting results. The previous UK-REBOA trial has not found any benefit in the intervention group and has even hinted at possible harm caused by the intervention. A major limitation of this study is the low number of interventions performed in participating trauma centres and the associated potentially insufficient experience with REBOA. The aim of this study is to evaluate the effectiveness of REBOA in a setting with already experienced providers.
The goal of this randomized control intervention study is to test the effect of i) a specific physical training for e-sport and ii) a general physical training on e-sport performance, compared to iii) not training physically at all. Participants are gamers and e-athletes who play at least >2hours peer week. The main questions it aims to answer are: - Does physical training have an effect on e-sport related abilities (hand grip strength, reaction, anticipation) - Does the training of specific elements, which aim at these abilities "out-game", transfer on the actual skills needed using a keyboard and mouse Participants will be randomly - but mediated by hours of playing per week - distributed in 1 of 3 groups. - Group 1 will 3 times per week for 30 minutes perform a specific physical training with focus on abilities needed in e-sport (grip strength, reaction, anticipation) over a timespan of 8 weeks. - Group 2 will perform a similar physical training (load, intensity) to Group 1, but without specific elements. - Group 3 will serve as control group without any training. Researchers will compare Group 1, Group 2 and Groups 3 to see if the different trainings (Group 1 and Group 2) have different effect on e-sport performance and if no training (Group 3) differs in e-sport performance development.
A large number of different organ functions are recorded in real time for patients being monitored in an intensive care unit. On the one hand, the measured values collected are used for continuous monitoring of vital parameters, e.g. blood pressure, heart rate and respiratory rate, but are also evaluated several times a day in conjunction with other data as part of ward rounds. In both cases, continuous monitoring from a limited number of parameters, but also in the distinct evaluation with a more extensive set of analyzable parameters, there are limitations in the evaluability even with all the care and expertise available: In continuous analysis, interpretation is limited by the restricted number of continuously recorded parameters described above. Although a large number of such measurements are possible, and at least theoretically a larger number of parameters could be measured, patient-specific limits such as patient cooperation, medical limits such as the significance of the measured values in specific situations, but also economic limits are often decisive in this context. Although accurate conclusions can be drawn from the continuous and therefore complete representation of aspects of human physiology, the limitation of the available parameters reduces the interpretability of the synthesis of different statuses. In the broader, more comprehensive assessments during visits at specific points in time, on the other hand, there are limitations due to, among other things, point recordings of individual measured values and the predefined visit times. Even if limit values are (or can be) defined for the measured data, and a consequence, e.g. a therapy step, is initiated if these values are exceeded or not reached, this alert can only be initiated retrospectively if these values are exceeded and a consequence can only be initiated retrospectively. In this situation, a pathophysiological change is already so far advanced that in many cases a compensation mechanism no longer functions adequately and turns into a decompensation situation. In this situation, the patients affected in an intensive care unit are in many cases in mortal danger. Both situations, continuous recording of a limited number of parameters and the evaluation of extensive data in the form of a snapshot could be optimized despite the limitations mentioned. Without changing the collection of data (time, scope, etc.), the possibilities for optimizing their interpretation and the consequences that can be derived from the interpretation remain. The interpretation of the data is primarily determined by the interpreters as the method of interpretation. Current approaches attempt to use machine learning (ML) methods to predict individual situations that recognize adverse events in the given data and at the same time allow alarms to be triggered pre-emptively, i.e. before a life-threatening situation occurs. Furthermore, there are already studies on the change of early warning scores in time series, which are, however, limited in their informative value for longer prediction periods.
This mono-center clinical investigation is intended to assess the safety and effectiveness of THIODERM ELATE for augmentation of very thin and thin lips in comparison with Juvéderm® Ultra 3.
The newest generation Lucia 621 has a step vault design that is claimed to provide excellent positional and refractive predictability. In order to explore the positional stability, anterior chamber depth stability is examined as marker for haptic buckling comparing positional behaviour after conventional and femtosecond-laser assisted cataract surgery.
The goal of this clinical trial is to compare plain old balloon angioplasty with sirolimus-coated balloon angioplasty in patients with an arteriovenous shunt stenosis. The main question we aim to answer is, how patency is affected by each of the randomised treatment modality.
