This proof-of-concept study aims to evaluate the feasibility, acceptability, and potential benefits of a novel multimodal approach: the micro-choice-based intervention.

Prostate cancer remains one of the leading causes of cancer-related morbidity and mortality among men. While PSA-based screening has been associated with reduced prostate cancer mortality, it also results in substantial overdiagnosis and overtreatment of clinically insignificant disease. Biparametric magnetic resonance imaging (bpMRI) has emerged as a promising imaging modality to improve the detection of clinically significant prostate cancer while reducing unnecessary biopsies. In this prospective follow-up study, men who previously participated in prostate cancer screening and had no evidence of malignancy at baseline will be invited to undergo repeat screening approximately five years later. The study aims to evaluate the longitudinal performance of repeat screening using PSA and MRI, determine the incidence of newly detected clinically significant prostate cancer after an initial negative screening, and assess changes in imaging and clinical findings over time. The results will provide evidence on the value and optimal interval of repeat prostate cancer screening in men with an initially negative evaluation.

This in-vivo study investigates early (48h), mature (2 weeks) and long-term (3 months) biofilm formation and composition on temporary push-on cones (exchangeable conical rings) made of noble-alloy-based materials (Pagalinor, PA) in comparison to Titanium-6Aluminum-7Niobium alloy (TAN) presently used in the transmucosal portion of dental implant abutments.

The goal of this clinical trial is to compare two strategies for closing the main artery access site in adult patients undergoing transcatheter aortic valve implantation (TAVI) through a blood vessel in the leg (transfemoral access). The main questions it aims to answer are: Does using a single suture device lower the rate of access-related vascular complications compared to using a hybrid combination of a suture device and a plug-based closure device? How do the two closure strategies compare regarding bleeding complications, procedure time, and time to complete vessel sealing? Researchers will compare a single-suture closure strategy to a hybrid closure strategy (one suture plus one plug-based device) to see if using a single suture reduces vessel-related complications and improves patient safety after TAVI. Participants will: Undergo standard pre-procedure screening and TAVI via the main artery in the leg as part of routine medical care. Receive an initial single-suture placement before the large TAVI delivery system is inserted. Be evaluated after sheath removal for initial bleeding control; qualifying participants will then be randomly assigned (1:1) to either receive no additional device (single suture group) or receive a plug-based closure device (hybrid group). Have their heart and access site monitored during hospitalization, including laboratory checks and imaging prior to discharge. Complete a 72-hour safety and complication evaluation.

This study aims to assess the influence of sensory stimulation on diet-induced energy expenditure by way of a clinical cross-over trial in 24 healthy participants either receiving a meal bolus with (orally) and without sensory stimulation (nasogastric-tube).

Heart failure (HF) occurs when the heart is no longer able to pump blood effectively throughout the body. This leads to symptoms that gradually worsen over time and are often mistaken for normal signs of aging. Because of its insidious onset, early detection is challenging. Both patients and healthcare professionals are often insufficiently aware of the early signs and symptoms of HF, resulting in delayed diagnosis. Consequently, timely initiation of treatments that could slow disease progression, improve quality of life, and reduce hospitalizations is often missed. Although a simple blood test measuring NT-proBNP levels can facilitate the early diagnosis of HF, it is not routinely used in clinical practice. The aim of this study is to evaluate whether a combined strategy for the early diagnosis and treatment of HF can reduce hospitalizations. This strategy includes: 1. increasing awareness of HF among patients and physicians, 2. using NT-proBNP testing for the early detection of HF in high-risk patients, and 3. promptly initiating guideline-directed HF treatment when the diagnosis is confirmed. The researchers will assess whether this strategy effectively reduces hospitalizations due to acute heart failure over an 18-month follow-up period.

This study aims to develop a standardized tool to assess intraoperative pain during cesarean delivery under neuroaxial anesthesia. The tool will draw on existing scientific literature, expert clinical opinion and the experiences of patients who have recently undergone caesarean delivery. Experts from multiple disciplines will participate in a structured consensus process (Delphi process) to identify and refine key assessment items. Patient interviews will be conducted to ensure that the tool reflects patient priorities and experiences.

This study investigates on the effect of two different operative techniques to treat abdominal wall hernias. The goal of this clinical trial is to learn if the eTEP (Extended totally extraperitoneal repair) technique leads to a better outcome than the IPOM (Intraperitoneal onlay mesh) technique. The main questions it aims to answer are: * pain after the operation * rate of complications * rate of recurrence and reoperations * quality of life. Participants will: Either be operated using the eTEP or the IPOM technique. Be followed up either in person or via email / phone call at day 1, day 7, day 14, 6 weeks, 6 months, 1, 3 and 5 years after the surgery to asses the above-stated main and some more outcomes.

This study investigates on the effect of two different operative techniques to treat large abdominal wall defects. The goal of this clinical trial is to learn if the minimally-invasive, robotically-assisted ventral hernia repair (RVHR) leads to a better outcome than the open ventral hernia repair (OVHR). The main questions it aims to answer are: length of stay after the operation rate of complications rate of recurrence and reoperations quality of life. Participants will: Either be operated using the RVHR or OVHR will be followed up either in person or via email / phone call at day 7, day 30, 6 months, 1, 3 and 5 years after the surgery to asses the above-stated main and some more outcomes.

The aim of the study is to assess whether targeting virulence factors by administering linezolid in addition to standard antibiotic treatment improves outcomes in patients with Staphylococcus aureus bacteraemia.

In this study, the investigators want to find out whether a new wearable sensor system, called the M2VS system, can reliably measure heart activity, blood pressure, and other vital signs over 24 hours during normal daily life. The investigators also want to compare the M2VS system with the standard devices currently used for long-term heart and blood pressure monitoring, such as a Holter ECG and an ambulatory blood pressure monitor (ABPM). This will provide an estimation of the accuracy of the M2VS system's ECG and blood pressure measurements compared to the standard devices. The aim of the study is to assess how reliable the M2VS system is in terms of data completeness and how comfortable it is to wear compared with the usual monitoring devices. In the future, the results of this study may help make the monitoring of heart and blood vessel diseases more comfortable and easier for patients.

The goal of this observational study is to understand the factors influencing the well-being and health of transgender and gender-diverse (TGD) individuals undergoing gender-affirming therapies in Switzerland. The study population includes TGD individuals aged 16 and older, at various stages of their medical transition, including those who have discontinued or detransitioned. The main question is: What are the key factors influencing the well-being and health outcomes of transgender and gender-diverse individuals undergoing gender-affirming therapies? Researchers will compare health outcomes across different subgroups, such as those at different stages of transition or detransition, to examine the effects of gender-affirming therapies. Participants will: Complete electronic questionnaires assessing gender congruence, quality of life, mental health, and other outcomes. Provide biological samples (e.g., blood, urine, stool, and skin swabs) for laboratory analysis. Undergo clinical evaluations related to endocrinology, fertility, dermatology, and urology as part of their routine follow-up.

This international, multicentre prospective cohort study will assess whether perioperative duration and magnitude of mean arterial pressure (MAP) outside of an individual's cerebral autoregulation (CA) limits using near-infrared spectroscopy (NIRS) and transcranial Doppler (TCD) are associated with adverse neurological events. It is to investigate whether patients with a higher burden of cerebral haemodynamic insults have an increased incidence or poorer neurological outcomes. Associations between neurologic outcomes, neurobiomarkers and genetic tests will be explored.

The aim of this study is to evaluate whether a new test using mannitol infusion can diagnose the cause of polyuria-polydipsia syndrome as accurately as the current standard test (hypertonic saline infusion) and to compare which test patients prefer. The goal is to identify a simpler and more patient-friendly diagnostic approach.
