This observational cohort study is designed to validate the CogCheck application as a risk prediction tool for postoperative delirium in patients undergoing cardiac surgery.
This is a single center prospective clinical trial with regard to efficacy and safety of radiofrequency ablation of papillary thyroid microcarcinoma.
This is a Phase IIa multicenter, double-blind, placebo-controlled study in healthy men to evaluate the spermatogenesis suppression after oral administration of Dimethandrolone Undecanoate (DMAU) alone or with Levonorgestrel (LNG) for 12 weeks versus placebo alone.
Serum, synovial fluid and skin biopsies from patients will be collected to the biobank with rheumatoid diseases. These samples will later be used for clinical and basic research, following approval of each specific study by the IRB. The investigators intend to extract protein, DNA and RNA from each sample.
This is a randomized, open-label, parallel-group multi-center study of Phase 3 study to assess the efficacy and safety of KN035 compared to standard of care (SOC) Gemcitabine-based chemotherapies in the treatment of participants with previously untreated locally advanced or metastatic biliary tract cancer. The primary hypothesis of this study is that participants will have a longer overall Survival (OS) when treated with combined therapy than SOC.

The aim of the present project is to reveal, using Functional Magnetic Resonance Imaging (fMRI) in drug users, a specific modulation of brain structures and circuits involved in cognitive control (and especially those of inhibitory control) and reward while subjects are performing under the influence of drug-associated cues and in various social contexts. This hypothesis, based on the animal work, is that the subthalamic nucleus (STN) should play a critical role in these processes. Addictive behaviour can be seen as a loss of control resulting from reduced inhibitory control, leading to compulsive drug use. These disorders are known to be associated with a hypoactivation of specific frontal regions such as the anterior cingulate cortex or the prefrontal cortex. For the present experiment, it is chosen to use a procedure well established for neurophysiological and behavioural assessment of inhibitory processes : the " stop-signal reaction time task ". This task requires to inhibit a motor response (press a button) at the onset of a stop signal (a tone) that occurs while the response is already engaged. In this task associated with fMRI, it was previously shown that the STN is involved in the control of inhibition. These results confirm our data in the rat, and especially those showing that STN lesions block the ability to stop. The stop signal task will thus be appropriate to study the effect of the social context on inhibitory processes in a population of cocaine users. In cocaine abusers, it was shown that inhibitory processes are affected. Here we aim at testing this population of subjects while they perform the stop task, but adding an implicit cognitive load induced by visual cues associated or not with cocaine intake. Since it want to assess the influence of a peer on both the performance and the associated cerebral activities, it will also control the presence of a peer observer in the procedure. There will thus be three experimental factors, one inter-subject factor (the experimental group, cocaine users or controls) and two intra-subject factors (cocaine associated or neutral cue; presence of a peer observer). The "stop-signal" task should induce increased activity of the STN that should be modulated by the cocaine-associated cues and by the presence of a peer.
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.
The present study aims to evaluate the efficacy of Arom Digest Slim in facilitating weight reduction along with a series of minimal nutritional interventions.
This study evaluates the injury in amateur football, adding different excercise into the habitual practice. There are three groups, one of them do eccentric excercise, another group doing proprioception exercise and the last group don´t do any exercise.
