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.
In vitro and in vivo data show promising results of adjunctive use of Chloroquine to standard tuberculosis therapy as Chloroquine enhances animicrobial effectiveness against intracellular MTB. To date, no safety data of the concurrent use of both treatments is availble. In a phase I trial, the investigators aim to evaluate safety and tolerability of the concurrent use of Chloroquine and standard anti-TB drug in healthy volunteers.
This exploratory study is to improve an established pain model by a new stimulation profile that allows preferential activation of C fibers that are of main clinical interest in chronic pain and also to generate a stable secondary hyperalgesia, which is of particular interest in the actual research of acute and chronic pain. It is to investigate if the specific activation of afferent sensory fibers and expected lower current intensities makes it more comfortable for the participant as motor neuron activation is much less pronounced at low current intensities. Therefore it compares the area under the curve (AUC) of hyperalgesia during electrical, intracutaneous 25 ms half-sine wave stimulation at a pain level of the numeric rating scale (NRS) of 6 out of 10 for 65 minutes compared to 500 µs rectangular pulses.
This study evaluates the incidence, patient characteristics and outcome of myocarditis after the COVID-19 mRNA vaccination in healthcare professionals.
This project aims to evaluate a male-specific psychotherapeutic program (MSPP) for MDD based on cognitive behavioral therapy (CBT). The primary goal is to test the superiority of the MSPP. This will be conducted in two groups of depressed men, namely eudonadal depressed men and hypogonadal depressed men receiving testosterone treatment (TT). In a randomized study design, the MSPP will be compared to a standard CBT and a waitlist control group, resulting in a total of six study groups. Both standardized psychotherapy programs will encompass 18 sessions delivered in a weekly manner, starting at study week 6 and continuing until study week 24. Aligned with the TT-related medical visits of the hypogonadal men, all participants will be followed up with clinical assessments and biosampling at weeks 0, 6, 15, 24, 36. In addition, a separate healthy control group will be examined, which will undergo only baseline assessments.
Total knee arthroplasty (TKA) is still considered the treatment of choice for painful osteoarthritis. In the last decades neutral mechanical knee alignment in the coronal plane has been considered the gold standard. However, the optimal TKA alignment is still debated. Today, component rotation measurements on three-dimensional (3D) reconstructed computed tomography (CT) images are considered the gold standard for assessing native preoperative alignment and TKA component position. In this study pre-and postoperative radiographic measurements, functional scores, and biomechanical parameters of patients with knee osteoarthritis will be assessed with the aim to investigate the relationship between deviations of TKA alignment from native preoperative alignment and clinical, functional and biomechanical alignment.
Pain, defined as a disagreeable sensory or emotional experience, is the most frequent symptom among patients admitted to the emergency department (ED). It is estimated that this symptom can be observed in almost 80% of patients upon their arrival to the ED. Despite several international recommendations concerning pain management, pain in the context of an emergency situation often remains underestimated. Medical procedures, such as venous or arterial blood collection, which are essential for diagnostic management and patient care, can also generate pain and a high level of stress for patients who are already weakened by their underlying condition. This is known as "care-related pain". Arterial blood gas (ABG) sampling is necessary to assess the gravity of the patient's condition and is a procedure conducted routinely in the ED. In a medium-size hospital (30,000 hospitalizations per year), approximately 1000 ABG tests are conducted annually. However, ABG collection is generally associated with pain and patient anxiety. In order to decrease the perception of pain linked to the collection of arterial blood, several methods have been studied, such as applying a topical anesthetic cream (lidocaine, xylocaine) or a subcutaneous infection of lidocaine prior to the procedure. Given that ABG collection is often performed in emergency situations and that the anesthetic cream must be applied at least one hour before sampling, this method is not adapted to emergency practices. In a previous study, a subcutaneous injection of lidocaine did not allow to significantly reduce pain during radial artery puncture. Similarly, another study using ultrasound guidance for ABG sampling did not show any significant decrease in pain, the rate of immediate complications, or physician satisfaction. Apart from the therapeutic tools commonly used, communication is a key element of care. In routine practice, caregivers inform patients that they are going to perform a potentially painful act. However, forewarning a patient that one will perform a painful act increases the perception of pain. It has also been shown that a communication strategy including the use of positive, kind or reassuring terms ("let me reassure you…", "are you comfortable?", "are you warm enough?") can contribute to decreasing the pain, while conversely, the choice of terms with a negative connotation ("okay, this might sting", "don't panic", "are you in pain?", "are you cold?") may increase the perception of pain and provoke a sense of discomfort. In the latter case, this is known as the "nocebo" effect. A communication strategy including reassuring terms, perceived by the brain as an agreeable information, allows to decrease the penibility dimension or connotes otherwise the pain in order to make it more bearable, thus modulating the painful perception. The objective of this strategy is that the painful message becomes less present as much as possible and that the patient benefits from a feeling of control. This procedure is widely used in hypnosis communication and is based on a neurobiological rationale, i.e., an increase in the secretion of endogenous opioids affecting the pain modulation networks decreases transmission in the pain pathways, thus leading to a release of dopamine in the striatum. This technique has already shown to be of benefit in patient management in various domains, such as anesthesia and pediatrics. Arrival at the ED can induce a particular state of consciousness linked to anxiety and a heightened suggestibility of negative communication. Although several studies have compared the impact of verbal attitudes, notably in the domain of anesthesia and mainly with staff already trained in hypnosis, to our knowledge, none has studied the effect of positive communication by caregivers or physicians among a patient population in the ED setting. Given the limited therapeutic options to relieve the pain and discomfort of blood collection performed in the ED, we would like to evaluate in this study the potential benefit of positive therapeutic communication on pain and anxiety among patients who require ABG compared to nocebo or neutral communication.
Study population The investigator set the sample size to 200 patients. Primary outcome - Diagnostic accuracy of ultrahigh field MRI (T7) compared to high field MRI (T3 or less) for detection of meniscal injuries associated with acute ACL injury Secondary outcome - Influence of 1) Location of injury and 2) meniscal tear pattern (modified WORMS18,19) on the sensitivity of high field MRI compared to ultrahigh field MRI for detection of meniscal tears
The study is designed as an open label, multi-center, Phase 1 study of single agent tinostamustine, used as adjuvant treatment in patients with newly diagnosed GBM who are MGMT unmethylated and have completed concomitant treatment with temozolomide and radiation. Treatment with adjuvant tinostamustine will start within 5 weeks of completion of concomitant temozolomide and radiation. The study is designed to define the MTD by evaluating toxicities during dose escalation. Tinostamustine will be administered on Day 1 of a 21-day treatment cycle. The total number of treatment cycles is 12 for patients who continue to benefit from treatment without disease progression or intolerable toxicity. Patients will enter a "3+3" design with dose escalation/de-escalation depending on safety from the last treated cohort.
The behavioral and psychological symptoms of dementia affect up to 80% of long-term facilities residents with severe dementia. They seriously alter the quality of life of patients, relatives, and health professionals. Management involves correcting somatic and psychiatric factors and implementing non-drug interventions. Nevertheless, often drug treatments must be introduced with the limitations related to their effectiveness and adverse effects. The investigators hypothesize that medical cannabinoids will improve neuropsychiatric and behavioral symptoms of patients with severe dementia. The investigators assessed the feasibility and safety of administering a cannabis oil that contains tetrahydrocannabinol (THC) and Cannabidiol (CBD) during an initial study of about two years, observing an overall improvement, excellent tolerance to the treatment, and the possibility of reducing or even stopping other drugs. This research project aims to study the efficacy of medical cannabis oil in improving the quality of life of dementia patients experimenting with behavioral and psychological symptoms.
This is a multi-center, randomized, double-blinded, placebo controlled trial.
