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.
Often prosthesis users abandon their devices due to difficulties in prosthesis control and lack of motivation to train. To properly control a prosthesis, amputation patients must learn how to activate, isolate and sustain nerve signals to the muscles left at the stump. Results of clinical validations show that game-based training leads to an improvement in clinical parameters for prosthesis control and patient engagement.
Background: Malignant tumors may lead to a catabolic state with loss of muscle and adipose tissue. The full picture of catabolism is termed cachexia and is associated with significant morbidity and mortality of cancer patients. Although the full picture is rarely observed up to 50% of children with cancer suffer from significant malnourishment. Additionally to tumor-induced catabolism, side-effects of chemotherapy may be problematic for the patients. In this regard up to 60% of children suffer from gastrointestinal mucositis presenting with nausea, vomiting, diarrhea or constipation and abdominal pain. In the worst case, mucositis may lead to bacterial translocation with life-threatening inflammatory response. Clinically this may require a reduction of the dosage or the number of chemotherapy cycles resulting in reduced effectivity. Up to now the therapy of mucositis is only symptomatic. Recent research of the applicant has shown a significant reduction of Lactobacilli in mice with neuroblastoma (a malignant childhood tumor). The dysbiosis was associated with catabolism, increased gut permeability and inflammation. Astonishingly, chemotherapy alone also leads to a significant reduction of Lactobacilli compared to sham mice, which may be linked to the development of mucositis clinically. Overall, the intestinal microbiome seems to play an essential role in the development of tumor-associated catabolism and chemotherapy-induced mucositis. Aim: The aim of this project is to determine if the changes in the intestinal microbiome observed in mice can also be seen in children with neuroblastoma. Methods: One part of the study will include 10 children with neuroblastoma (inclusion after verification of the diagnosis) and 10 healthy controls. The fecal microbiome will be determined by 16S-ribosomal deoxyribonucleic acid (rDNA) pyrosequencing. Volatile organic compounds in the breath will be sampled and measured by Gas Chromatography/Mass Spectroscopy. A basic science human work package will address the question if there are differences. In the second part serial investigations in children with neuroblastoma will assess whether or not these patients show alterations of the intestinal microbiome under chemotherapy.
The aim of this Register Trial is to systematically study the epidemiology, risk factors, liver function as well prognosis of patients with vascular liver diseases. Furthermore, important clinical parameters will be assessed in order to evaluate patients' coagulation status and in order to develop new biomarkers derived from blood, urine, stool or ascites of patients as well as histological samples from the upper / lower GI-tract or the liver in order to better understand the natural history of vascular liver diseases.
Comparison of the astigmatism reducing effect of a toric IOL with a non toric IOL in eyes with low corneal astigmatism.
Investigate if caffeine accumulation in human lens epithelial cells after oral caffeine intake is sufficient to prevent from experimental ultraviolet radiation induced apoptosis
This study is designed to evaluate the long-term efficacy and safety of mirikizumab in participants with moderately to severely active ulcerative colitis (UC). The study will last up to 3 years. Participants who complete the 3-year study may continue to receive mirikizumab until it is (outside of this study) in their country or until they meet other discontinuation criteria.
The heterotopic gastric mucosa found in the cervical esophagus was first described in 1805 and affects 10-15% of individuals undergoing esophagogastroduodenoscopy. It leads to laryngopharyngeal reflux (LPR), which causes symptoms like globus sensation, hoarseness and chronic cough. The Reflux Symptom Index (RSI) that ranges from 0-45 measures LPR. Scores greater than 13 are considered to be pathologic. Currently, patients that suffer from symptoms of LPR and present with a heterotopic gastric mucosa are routinely offered radiofrequency ablation (RFA) as curative treatment. Up to now, around 40 patients were already treated at the department of Surgery with 90% histologic eradication rates after 2 treatment sessions and no reported serious adverse event. Nevertheless, the placebo effect could also be responsible for perception of improving symptoms. Therefore, this prospective sham-controlled trial was designed to exclude the placebo effect. As the device is already approved and routinely used for focal ablation safety data are already available. Up to now, there were no major adverse events, whereas only 10% of patients describe a sensation of irritated throat that dissolves within the first three days after treatment.
RATIONALE: The use of tailored axillary dissection as a tailored procedure will avoid surgical overtreatment by selectively removing the lymph nodes that are affected by the cancer, thereby sparing many women the unnecessary complications of a radical surgery, providing a better quality of life while keeping the same efficacy. PURPOSE: The phase III trial is evaluating the optimal treatment for breast cancer patients in terms of surgery and radiotherapy.
The Swiss Paediatric Airway Cohort (SPAC) is a national, prospective clinical cohort of children and adolescents who visit physicians in Switzerland for recurrent wheeze, cough, and exercise- or sleep-related respiratory problems. SPAC aims to answer important questions on clinical phenotypes, prognosis, diagnosis and treatment. SPAC is part of routine care, and only clinically indicated investigations are done. The comprehensive baseline assessment includes a detailed questionnaire to families, plus test results, diagnoses and treatments from hospital records. Follow-up is via monthly questionnaires the first 12 months and thereafter annual questionnaires to families, and data from follow-up visits. Currently, 4344 patients from 10 clinics and hospitals in Switzerland (Aarau, Basel, Bern, Chur, Horgen, Lausanne, Luzern, St. Gallen, Worb, Zurich) have been enrolled. SPAC provides real-life data on children visiting the Swiss health care system for common respiratory problems. It will provide a research platform for health services research, and for nested clinical and transitional studies. Publications and plain language summaries are listed on the study website: https://www.spac-study.ch/publikationen/
The aim of this study is to compare two different surgical methods for treating benign prostatic obstruction (BPO). The investigators are going to compare the risks and benefits of bipolar transurethral resection of the prostate (TURP) and bipolar transurethral enucleation of the prostate (BipolEP). Furthermore, the investigators are going to compare the amount of tissue resected per minute, in order to assess the efficiency of each surgical method. It is a prospective, interventional, multi-centre (2 centres total), randomized trial. Approximately 84 patients will be included
