Wide Area Transepithelial sample Esophageal Biopsy combined with Computer assisted 3-Dimensial Tissue Analysis (WATS) for the detection of High Grade Esophageal Dysplasia and Adenocarcinoma: A multicenter prospective, randomized, tandem study

To evaluate the utility of the WATS system, as a potential substitute for the random sampling method that is currently recommended as an adjunct to targeted biopsy

Predicting the effect of transcranial direct current stimulation on brain excitability

Primary Objective: To verify the main effect of TDCS on brain excitability and the interaction effects of BDNF genotype and APLM latency on this main effect. Secondary Objectives: Compare different prediction models for the main effect of TDCS in a…

Self-initiated versus fully automated method for the measurement of blood pressure at home

The main goal is to assess the difference in average systolic bloodpressure between self-initiated and fully automated measurement, thereby evaluating the influence of the *auto-cuff* response in an out-of-office setting. Secondary goals are…
