Clinical trials

Evaluation of the effectiveness of a new mandibular advancement device (BioMAD) in the treatment of obstructive sleep apnea.

We hypothesize that the ventilatory mode Bilevel Positive Airway Pressure without any synchronization (BIPAPasynchro) may facilitate the weaning process of patients intubated with acute hypoxiemic respiratory failure (AHRF) by obviating the problem of patient-ventilator asynchrony. In order to prove this hypothesis a large randomized controlled study should be perfromed comparing BIPAPasynchro versus pressure support ventilation (PSV), the most widely used ventilatory mode during the weaning process. In order to do so, a feasibility trial to demonstrate the ICU personnel can effectively use a non-standard ventilatory mode should be first performed. The objective of our study is, thus, to demonstrate the feasibility of using BIPAasynchro in the Lausanne Adult ICU.

This study compares the effectiveness of low-field MRI (0.55T) with high-field MRI (3T) in prostate cancer screening and image quality. It consists of three phases: optimizing the low-field MRI protocol with healthy volunteers, evaluating image quality in patients with metallic artifacts (like hip prostheses), and assessing low-field MRI in patients with suspicious prostate lesions found on high-field MRI.

currently, PROMs and PREMs are not routinely collected and compared among medical inpatients of Swiss university hospitals, nor is a standard set of PROMs and PREMs available for use in Swiss hospitals. The project aims to examine trends in patient-reported outcomes (PROMs), including symptoms, quality of life, and distress, in multimorbid hospitalized patients from admission to 30 days post-discharge. It will also investigate whether PROMs at discharge are linked to the risk of readmission or emergency visits and explore how these outcomes differ in patients who receive low-value care. Additionally, the project will assess the relationship between patient-reported experiences (PREMs) and the provision of low-value care during the hospital stay.

This is an open-clinical trial to study the feasibility of a brief manualized psychotherapy for mothers interpersonal violence-related posttraumatic stress disorder (PTSD) and their very young children ages 1-3 years, entitled: Clinician-Assisted Videofeedback Exposure Approach Therapy (CAVEAT). This project, to be conducted with referred mothers and children to an academic medical center ambulatory care setting, intends to pilot along with the manualized intervention, pre- and post-intervention measures for up to 10 dyads over 2 years.

The first study proposed is a small (n= 10 to 12 maximum) open feasibility trial of CAVEAT which is a 16-session manualized brief psychotherapy prototcol that is designed to help mothers of infants and young children, whereby the mothers have been exposed to interpersonal violence (i.e. childhood maltreatment and family violence, intimate and non-intimate partner violence, interpersonal combat and or other forms of terrorism or political violence including physical and sexual assault) and who have developed related post-traumatic stress. The treatment uses an integration and extension of evidence-based techniques: Modified Interaction Guidance, Prolonged Exposure Therapy for PTSD, Child-Parent Psychotherapy, and Minding the Baby, in order to help mothers with post-traumatic dysregulation and difficulty in their maintaining sensitivity during challenging parent-child interactions (i.e. when mothers are confronted with child helpless states, emotion dysregulation, negative affect and child aggression). Outcome measures will initially include: maternal attributions towards her child (i.e. perception of child's personality), maternal-child behavior, and maternal-child symptoms of attachment disturbance and PTSD. This feasibility study is meant to perfect the manual and to prepare for an initial open trial with a larger clinical sample including analysis of pre- and post-intervention measures before further randomized control study can be done.
