There are about 25560 clinical studies being (or have been) conducted in Germany. 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.
The goal of this observational study is to learn about the long-term development and outcomes of different treatment patterns of patients who initially participated in the TripleTRE study. The primary objective of this non-interventional follow-up study is to assess the long-term real-world clinical outcomes, including disease progression and survival rates, in patients who initially participated in and completed the randomized TripleTRE trial. Planned observation duration per patient is a minimum of 3 years.
The aim of this study is to assess the influence (i.e. type and timing) of post-endodontic restorations on the survival of root canal-treated teeth and to determine the influence of patient-, tooth-, treatment-, and restoration-specific parameters on longevity. Patients who received a root-canal treatment between 1998 and 1999 with subsequent placement of an indirect restoration (e.g. crown, partial crown) will be retrospectively analyzed. Patient-, tooth-, treatment-, and restoration-specific parameters will be obtained from digital and paper-based dental records. Survival and success of the root-canal treatments will be assessed using Kaplan-Meier statistics. Mean annual failure rates (mAFR) and median survival time will be calculated (Kaplan-Meier statistics). Potential predictive factors will be tested using log-rank tests and multi-variate Cox-regression analysis.
The aim of this study is to determine and compare the longevity of single-tooth cast restorations made of precious metal vs. non-precious metal (e.g. partial crowns, crowns) and to determine the influence of patient-, tooth-, treatment-, and restoration-specific parameters on longevity. Patients who received single-tooth cast restorations made of precious metal or non-precious metal (e.g. partial crowns, crowns) between 1997 and 2022 will be retrospectively analyzed. Patient-, tooth-, treatment-, and restoration-specific parameters will be obtained from digital and paper-based dental records. Survival and success of the restorations will be assessed using Kaplan-Meier statistics. Mean annual failure rates (mAFR) and median survival time will be calculated (Kaplan-Meier statistics). Potential predictive factors will be tested using log-rank tests and multi-variate Cox-regression analysis.
This study aims to analyze the fatty tissue architecture of the subcutaneous tissue in patients from the plastic surgery department. Plastic surgery patients show a wide variety of subcutaneous fatty tissue structures during clinical examination. These include patients with edema of the extremities such as lipedema or lymphedema. Fatty tissue architecture plays a major role in our everyday lives, as wound healing and scar formation, for example, are influenced by the blood flow to the overlying skin. The fatty tissue architecture, especially in the subcutaneous fatty tissue, also plays a major role in our appearance. An analysis of the architecture can potentially provide information about the genesis of different skin fold formations. The aim of this study is to quantitatively describe structural differences in adipose tissue architecture. Adipose tissue architecture is still a largely unexplored area because imaging has not been possible to date. MSOT imaging is similar to conventional sonography in that a transducer is placed on the skin and energy is supplied to the tissue by pulsed laser light instead of sound. On a macroscopic level, this leads to a constant change of minimal oscillations of individual tissue components. The resulting sound waves can then be detected by the same transducer. Previous studies have shown that the quantitative determination of hemoglobin can be used to obtain information on blood circulation and inflammatory activity. In the extended spectrum, in contrast, not only hemoglobin and its oxygenation stages but also other biomarkers such as collagens and lipids can be detected. This is very useful for imaging of fat, lymphatics and normal and abnormal blood vessels in vascular malformations. This process was largely researched by the working group of Prof. Ntziachristos (Helmholtz Center Munich and Technical University of Munich) and Prof. Razansky (Eidgenösische Technische Hochschule Zurich) and is being further developed into a clinically applicable technology and sold commercially by the company iThera. As a first series of demonstrative clinical studies following rigorous technical development, MSOT will serve as a key tool for research partners in the investigation of several diseases that remain poorly-understood and have limited treatment options. These parallel studies will focus on lipedema and lymphedema as well as vascular malformations - three distinct disease groups with similarly unmet clinical needs for appropriate imaging modalities and high potential of translation to further major disease areas. By focusing on two unrelated diseases, this project will show the wide-reaching application of this innovative imaging approach. Following successful proof-of-principle validation in a clinical research environment, full exploitation and dissemination of the results will strive to deliver MSOT to the greater scientific community. The main objectives are to confirm/validate the spectral profile of fat and vasculature on MSOT in lipedema patients, to establish the spectral profile of vascular malformations based on MSOT for adults and children and to establish the spectral profile and imaging of lymphatic vessels. With a detailed analysis of the architecture, our understanding of the physiology and pathology of the skin may be enhanced.
The overarching goal of the project is to determine whether differences in stomach-brain coupling contribute to key symptoms of major depressive disorder (MDD) and whether transcutaneous non-invasive vagus nerve stimulation (tVNS) may serve as a non-invasive intervention to improve aberrant interoceptive signaling in participants suffering from MDD.
With this clinical trial we investigate whether auricular acupuncture during adjuvant endocrine therapy has an improving effect on hot flashes, which are often perceived as psychologically and physically stressful in self-assessment of women with breast cancer. Empirical studies indicate that body acupuncture has positive effects on hot flashes. As auricular acupuncture offers a number of advantages over body acupuncture, a three-armed randomised controlled research design is being used to investigate whether hot flashes caused by endocrine therapy are also reduced by ear acupuncture. Balanced ear acupuncture will be compared with NADA ear acupuncture in terms of efficacy and effectiveness. In addition, the effects of the two forms of therapy on the patients' individual quality of life, fatigue, stress perception and sleep quality will be analysed.
This study is being conducted to evaluate the long-term safety and efficacy of ALZ-801 in Early Alzheimer's disease (AD) subjects with the APOE4/4 genotype. This is an open-label trial of treatment with ALZ-801.
The study is a workpackage in the German research consortium COLLPAN. The study will map collateral effects in terms of psychosocial and spiritual burden of informal caregivers during after the pandemic and identification/mapping of risk factors.It will also map available therapeutic and preventive interventions and relief of this burden for the present situation and for future pandemics.
Hereditary Hemorrhagic Telangiectasia (HHT), also known as Osler's disease, is a genetic disorder that leads to abnormal blood vessel formations. It primarily affects blood vessels in the skin, mucous membranes, and internal organs. The disease can be clinically diagnosed using the Curaçao criteria (1. Positive family history of HHT, 2. Recurrent and spontaneous epistaxis, 3. Multiple typical telangiectasias, 4. Organ involvement with vascular malformations, especially in the liver, lungs, gastrointestinal tract, or brain); if a patient meets at least 3 criteria, the diagnosis of HHT can be established. Patients with HHT often have telangiectasias on their faces. Additionally, many patients suffer from anemia, which can result in a pale and potentially tired appearance. Patients with HHT may be less satisfied with their appearance due to the aesthetic changes in their faces and may also experience psychosocial impairment. To further investigate this, various validated questionnaires (FACE-Q©, PROMIS-Profile-29+2, EQ5D), as well as routinely collected clinical data (e.g., laboratory values including hemoglobin levels, Curaçao criteria, smoking status, alcohol consumption, and the Epistaxis Severity Score (ESS)) will be used.
The Revita DMR Post Market Pilot Clinical Registry is a post-market, prospective, observational, noninterventional clinical registry in patients with T2D in Germany undergoing the Revita Procedure with the CE marked Revita System (Fractyl Health, Lexington, MA, USA) in accordance with its intended purposes. Patient's participation in this study has no impact on his or her indication or opportunity to receive therapy. Patients are to be treated in compliance with the current Revita System's IFU of the CE marked Revita System as well as according to medical society guidelines and physician discretion.
