There are about 9403 clinical studies being (or have been) conducted in Switzerland. 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.
This is a multicentre retrospective and prospective cohort study with the goal to develop a well-characterised multimodal image database of eyes with intermediate AMD with and without early atrophy. The main objectives are: 1. Develop a collaborative well-characterised database on intermediate AMD with or without early atrophy. 2. Grading of these images to explore imaging markers of progression. 3. Develop predictive models as a secondary analysis of our dataset. This study will recruit around 1.000 eyes in 6 months. All consenting patients who have had at least 3 clinic visits with multimodal imaging done at least at 6 months interval between 2 visits and meet the inclusion and exclusion criteria will be included in the study for retrospective data collection. Those with one visit remaining to complete 2 years, images will be acquired prospectively. In addition to the images, routine demographic data (age and sex) and available visual acuity (VA) (BCVA if possible, VA with Pinhole or VA with patient's glasses) will be collected. Multimodal imaging includes mandated macular OCT with or without enhanced depth imaging and infrared imaging. Fundus autofluorescence (AF) and multicolor imaging are optional. All imaging must be done on Heidelberg Spectralis system.
This study will evaluate the clinical impact and utility of digital health solutions (DHS) on health outcomes and health-care resource utilization in people receiving systemic anti-cancer treatment (approved or non-approved) in clinical practice.
The aim of this project is to investigate the effect of xylitol (given as pre-load), compared to sucrose, Ace-K, and water on energy intake during a subsequent ad libitum test meal in healthy participants. Furthermore, the release of GI hormones, glycemic control, appetite-related sensations, GI tolerance, sweetness and liking in response to the pre-loads will be investigated.
Carbohydrate count marks the cornerstone of Type 1 Diabetes management. Eventhough it is a crucial task, it is burdensome and prone to error. Therefore, the investigators want to explore the effect that SNAQ, a food analyser app would have in glycaemic control by facilitating the task of carbohydrate estimation.
The primary purpose of this study is to compare pembrolizumab/vibostolimab to pembrolizumab with respect to recurrence-free survival (RFS). The primary hypothesis is that pembrolizumab/vibostolimab is superior to pembrolizumab with respect to RFS as assessed by the investigator in participants with high-risk resected Stage IIB, IIC, III and IV melanoma.
Tooth extraction is followed by marked alterations of the tissue volume. The resorption process of at least the surrounding mucosa can be altered by using immediate implant placement and additional features such as immediate provisional crown, platform switching and grafting the gap between implant and buccal bone plate. The support of the gingival margin with a provisional crown led to an increase of buccal gingival tissue. Teeth scheduled for extraction will be used to study the effect of a customized healing abutment. The following groups will be randomly assigned: Control: A commercially available healing abutment will be screwed on top of the implant and a collagen sponge will be used to protect the graft. Test: A customized PEEK abutment mimicking the subgingival emergence of the extracted tooth will be screw retained on top of the implant to seal the extraction site.
The primary objectives of this study are to evaluate the safety and tolerability of a switch to Doravirine/Islatravir (DOR/ISL) compared with continued baseline antiretroviral therapy (ART), through Week 48; and to evaluate the antiretroviral activity of a switch to DOR/ISL compared with continued baseline ART at Week 48. The primary hypothesis is that DOR/ISL is non-inferior to continued baseline ART, as assessed by the percentage of participants with HIV-1 ribonucleic acid (RNA) ≥50 copies/mL at Week 48, with a margin of 4 percentage points used to define non-inferiority.
This is an exploratory observational study. Video footage is used to review all 64 matches in the football tournament. All players actions are registered using the FIFA football language, such as, pass completed, clearance, etc. Potential injury incidents are registered, and for each incident the injury location, contact type, player reaction, velocity, location, game reaction, referee reaction, medical staff on pitch, and outcome (e.g. substitution) are also registered.
The goal of this observational study is to assess the risk of viral infections in patients receiving hematopoietic stem cell transplantation (HSCT) from a haploidentical donor compared to those who receive HSCT from a HLA-matched donor. The main question it aims to answer is: to describe which viruses are replicating in the blood of the above two patient groups on the day of transplantation and at 1, 3 and 6 months after transplantation. Blood samples taken as part of routine care on the day of transplantation and at 1, 3 and 6 months post-transplantation visits are analyzed and the types and amount of viruses detected in the two groups of patients are described.
A retrospective cohort study will be conducted on patients who were hospitalized at the University Hospital Basel (USB), University Hospital Bern (Inselspital), University Hospital Geneva (HUG) and the University Hospital Zurich (USZ) with the diagnosis of AMI and/or AHF. Baseline data will be collected in the hospital during treatment will be complemented by a short outcome evaluation.
