There are about 25301 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 clinical trial is intended to evaluate the efficacy, safety and economic benefit of coronary lithotripsy compared to other additional procedures (cutting or super high pressure balloon angioplasty, ablative procedures) in lesion preparation and interventional treatment of severely calcified coronary stenoses.
Retrospective chart review study to elucidate the genotype and phenotype of patients with PRPF31-associated retinitis pigmentosa and asymptomatic carriers of the respective variant(s)
Background: The major aim of this study is to compare the effects of emotion focused (experiential) and cognitive interventions of schema therapy (ST) on emotion regulation deficits in patients with borderline personality disorder (BPD) according to DSM-V (alternative model) criteria. In a randomized, single-blinded parallel-group design clinical effects as well as effects on neurotransmitter metabolism and connectivity will be compared. Method: While the 9-weeks treatment protocol of particular interest includes emotion focused interventions (ST-EF, n=60) such as chair dialogs, imagery rescripting or role play, the active control condition (ST-AC, n=60) is restricted to cognitive interventions, e.g. psychoeducation or pro/contra discussions. MEGA-PRESS 1H-MR spectroscopy and resting-state functional MR imaging (rs-fMRI) will be used before/after treatment protocols (T0-T1) and 6 months after the end of therapy (T2) to assess the effects on glutamate (Glx) and GABA metabolism in key regions of the target networks (executive control network, ECN: dorsolateral prefrontal cortex, DLPFC; salience network, SN: anteromedial cingulate cortex, aMCC; default mode network, DMN: pregenual cingulate cortex, pgACC) and to investigate the corresponding altered connectivity in these networks. The biological aberrations at T0 as compared to healthy controls (n=60) and treatment effects (at T1 and T2, n≥40 in each condition) on these aberrations will be linked to clinical effects measured by an extensive test battery with particular interest on emotion regulation, and specified by the Reliable Change Index (RCI). For longitudinal data mixed model analysis will be performed. The main questions are (1) whether the emotion regulation deficit and the pattern of BPD-specific symptomatology are associated with a specific pattern of Glx and GABA concentrations in the DLPFC, aMCC and pgACC and corresponding deviations of functional connectivity within the ECN, SN and DMN. Hypothesis: Depending on primary and secondary outcome measures at T0, altered RSFC in the DMN, SN and ECN and corresponding altered Glx or GABA concentrations are assumed. (2) whether both treatment conditions have different clinical effects on the ability to regulate emotions and whether the respective clinical effects are associated with the changes in neurobiological aberrations. Hypothesis: It is hypothesized that the ST-EF condition will improve emotion regulation skills more effectively than the control condition. Only in the ST-EF condition are higher response and remission rates expected in the primary and secondary outcome measures, as well as effects on the ECN, SN and DMN with corresponding changes in RSFC and Glx or GABA concentrations.
The aim of the planned study project is to assess the current situation regarding the treatment of patients with severe stroke at the neuro-critical care unit. Specifically, determination of whether the target parameters recommended in the guidelines for temperature, systolic blood pressure, mean arterial blood pressure, blood glucose, arterial oxygen partial pressure and arterial carbon dioxide partial pressure had to be maintained. From the planned data analysis, the need for the introduction of cerebrovascular bundles can be derived and planned.
Patients with head and neck cancer requiring definitive or adjuvant radio(chemo)therapy can take part in the study. The aim is to record the nutritional status and diet of the patients during the trial and regularly at a period of 8 weeks after irradiation and to reduce the rate of weight loss and malnutrition.
The objective of this study is to evaluate the efficacy of a eugenol-based product in improving the quality of toothbrushing and relieving areas of gingival discomfort. This is a randomized, controlled, parallel, examiner-blind clinical trial.
Acute mesenteric ischemia (AMI) is a severe condition that might occur after cardiovascular surgery. Several risk factors for AMI, such as multimorbidity, the use of vasopressors, and an increase in inflammatory markers have been identified in the past. However, these risk factors also seem to influence the blood and urine levels of I-FABP. This prospective pilot study intends to evaluate the value of perioperatively assessed I-FABP levels and to correlate these values with clinical or angiographic findings in mesenteric ischemia to improve a standardised diagnosis.
Hormonal transition periods during the menstrual cycle may predispose women to mental disorders. Hormonal fluctuations provide specific neuroendocrine conditions that modulate brain structure and function and these actions affect cognitive and emotional behaviors and affect energy and mood homeostasis. It is thought that these changes are driven by altered dopamine transmission. Here, we aim to examine (1) how sex hormones and dopamine are linked and also (2) how hormonal changes affect motivation, mood, and energy homeostasis. To this end, dopamine intervention will be tested on effort-based decision-making and motivational circuits in three hormonal stages (i.e., women in early-follicular phase (EF), women in mid-luteal phase (ML), and men). Additionally, we are testing the effects of hormonal status on metabolic indices and its effects on mood fluctuations in a period of a month. The investigator hypothesizes that women in EF cycle phase (1) have naturally less dopamine and show less effort, and (2) they show greater improvement in effort-based decision-making after Levodopa administration. We have exploratory outcomes about (3) sex differences in reward-learning with and without Levodopa administration and explore if these differences correlate with elevated female sex hormone levels. Moreover, it is hypothesized that (4) hormonal fluctuations affect energy homeostasis, thus women in their EF cycle phase have higher energy expenditure and (5) they report more negative mood than in their mid-luteal (ML) cycle phase.
It is currently unclear what activities aneurysms are involved in at the time of rupture. The aim of the study is to determine the activity performed at the time of aneurysm rupture.
Securing the airway through endotracheal intubation (ETI) is a fundamental skill for anaesthetists. It is used during surgery, in the intensive care unit, during periprocedural anaesthesia and in emergency medicine. The clinical relevance of airway management is demonstrated in particular by the fact that the main cause of serious anaesthesia-related complications lies in the area of airway management. increasing technological developments in recent years (e.g. video laryngoscopy [VL]) aim to reduce the complication rate in the area of airway management. however, there are currently a large number of VLs available, which differ massively in their application. Therefore, it is essential to systematically collect data and develop structured training in airway management, taking into account current technological developments.While endotracheal intubation is traditionally performed with a direct laryngoscope, indirect video laryngoscopy, with chip-based camera technology at its tip, has been introduced across the board in recent years and is now part of standard clinical and preclinical equipment. Doctors in advanced training are trained with a focus on direct laryngoscopy; the use of and training in indirect video laryngoscopy does not follow any standards; in addition, the decision as to which method of securing the airway is chosen has so far been the responsibility of the individual doctor in anaesthesiology, although there is a tendency for the VL to be associated with a higher success rate in the first intubation attempt, the so-called "first-pass success".The main aim of this clinical prospective, randomised controlled trial is to train anaesthetists in advanced training in conventional direct laryngoscopy on the one hand and indirect video laryngoscopy (VL) on the other, with a focus on tracking the progress of their skills after 200 intubations with regard to first-pass success.
