NCT ID: NCT04066946 Completed - Cicatrix Clinical Trials

Study for the Effects of Microcurrent Therapy on the Prevention and Healing of Brachioplasty Scars

Start date: March 3, 2020
Phase: N/A
Study type: Interventional

Prospective, single-centre two-arm randomized controlled trial. Both groups receive standard wound care + hydration. The intervention group also receives microcurrent therapy. Patients with surgical incisions from bilateral Brachioplasty procedures will be included in this study. One arm will be randomized in the intervention group and one arm in the control group. Objective and subjective outcomes are registered. The aim of this study is to investigate whether the outcomes of the patients of the intervention group differ significantly from the patients in the control group.

NCT ID: NCT04065022 Completed - Tremor, Limb Clinical Trials

The Trans-cutaneous Effects on Physiological Tremor Entertainment During tACS

Start date: June 20, 2017
Phase: N/A
Study type: Interventional

Transcranial alternating current stimulation (tACS) is a noninvasive neuromodulation method that works by passing alternating electric current between electrodes where at least one of them is attached to the head. This has been shown to have effects on the motor system, cognition and behavior. The exact mechanism by which tACS causes such effects is not fully understood. Some studies suggests a contribution from the stimulated peripheral nerves present in the scalp rather than direct brain effects. To test this hypothesis two arms will be done. First, 12 subjects (arm 1) will be stimulated using focused 4x1 montage with gel-filled cup-electrodes over the motor cortex and the effects will be compared between anesthetized and non-anesthetized scalp. The effects of anesthetizing the scalp will be tested on three different stimulation amplitudes off (0 mA), low (0.5 mA) and high (2.5 mA). Then, 10 subjects (arm 2) will be stimulated over the contralateral arm to exclude any direct brain stimulation effects and to test if peripheral nerve stimulation can entrain the tremor. Three outcome measurements will be measured during the experiments which are: tremor entrainment, sensation intensity and sensation threshold.

NCT ID: NCT04064489 Completed - Clinical trials for Venous Thromboembolism

Thromboembolic Risk Stratification by TRiP(Cast) Score to Guide Physicians in Preventive Treatment Prescriptions for Patients With Lower Limb Trauma Requiring Brace or castING.

CASTING
Start date: June 16, 2020
Phase: N/A
Study type: Interventional

Non-surgical traumas to the lower limbs that require orthopedic immobilisation (plaster or splint) are a frequent reason for going to accident and emergency. Due to venous stasis caused by immobilisation, hypercoagulable states and vascular injuries brought on by the trauma, these patients are at risk of developing VTE. For this reason, it is current practice in France and Belgium for the majority of patients to receive a preventative anticoagulant treatment. However, the benefit of this treatment, which has a considerable cost, is controversial. Contrary to French recommendations, American recommendations from 2012 actually advise against systematic preventative medicine, with prevention appearing to be effective primarily in studies with restrictive inclusion criteria. The most significant randomised controlled study on the subject did not show the benefit of low-molecular-weight heparin (LMWH) on the rate of symptomatic VTE among 1,435 non-selected patients. Therefore, in 2017, the Cochrane meta-analysis concluded that stratification of the risk of thromboembolism is required. For this purpose, in collaboration with the Dutch team of Nemeth et al. we have recently developed a risk stratification model that takes into consideration the patient's characteristics, the type of immobilisation and the severity of the trauma: the TRiP(cast) score. This score is applied retrospectively to a large cohort and demonstrates excellent prognostic performances (AUC (area under the curve) of 0.74). In addition, when using a <7 limits, it makes it possible to identify a large group of patients at very low risk of developing VTE (negative predictive value: 99.2%). The aim of the CASTING study is to prospectively demonstrate the reliability and utility of the TRiP(cast) score by showing that patients with orthopaedic immobilisation of a lower limb who are not receiving preventative treatment on the basis of a TRiP(cast) score of <7 have a very low rate of symptomatic VTE, which allows for a significant reduction in prescriptions of anticoagulants in comparison with prior practices.

NCT ID: NCT04063969 Completed - Healthy Volunteers Clinical Trials

Analysis of the Radiation Safety Climate in the Hybrid Angiography Suite

Start date: January 24, 2019
Phase:
Study type: Observational

This study aims to measure the radiation safety climate in the hybrid angiography suite using self-assessment and to investigate the relationship of radiation safety climate with their self-reported safety behaviors. The hypothesis is that a radiation safety climate does exist and can be measured using self-assessment. Additionally, it is expected that the radiation safety climate positively influences radiation safety behaviors.

NCT ID: NCT04063423 Completed - Clinical trials for End Stage Renal Disease

Non- Clinical Coagulation Activation During Hemodialysis

NC-Coact
Start date: October 25, 2018
Phase:
Study type: Observational

Every patient included in the study will undergo 1 conventional hemodialysis treatment, ie 1 study visit. During the conventional hemodialysis treatment lasting 4 hours, 2 blood samples will be taken at different time points (5 minutes after dialysis start and 240 minutes after dialysis = at the end of the dialysis session) to evaluate coagulation activation (TAT, PF1+2). Hemodialysis session parameters (arterial and venous pressure, TMP, OCM, BVM and prefilter pressure) will be noted at different time points (T5, T30, T60, T120, T180, T240). After discontinuation of the dialysis session, total cell volume will be measured using the Renatron II system® and the number of open fibers will be determined using micro-CT scanning.

NCT ID: NCT04059224 Completed - Stage IV Melanoma Clinical Trials

TraMel-WT: A Trial of Trametinib in Patients With Advanced Pretreated BRAFV600 Wild-type Melanoma

TraMel-WT
Start date: January 28, 2019
Phase: Phase 2
Study type: Interventional

This phase 2 trial will investigate the efficacy and safety of trametinib and dabrafenib in patients with advanced BRAF V600 (v-Raf murine sarcoma viral oncogene homolog B) wild-type melanoma (stratified according to BRAF V600 wild-type/NRAS (neuroblastoma Ras viral oncogene homolog) mutant and BRAF V600 wild-type/NRAS wild-type melanoma patients) that have been pretreated and progressed following treatment with PD-1- (programmed cell death-1) and CTLA-4-blocking (cytotoxic T-lymphocyte-associated antigen 4) immune checkpoint inhibitors. The investigators hypothesize that treatment with trametinib will result in objective antitumor activity. In order to improve the tolerability and optimize the dose intensity of trametinib, a minimal dose of dabrafenib will be added to prevent and manage trametinib-related skin toxicity.

NCT ID: NCT04056351 Completed - Clinical trials for Proximal Humeral Fracture

A Research Study to Understand and Predict the Failure of Shoulder Fracture Fixations Using Computer Simulations

PHILOS-SIM
Start date: August 2, 2019
Phase: N/A
Study type: Interventional

Fractures of the shoulder, the so-called proximal humeral fractures, can be treated with locking plates that have shown good results in clinical practice, but complications can occur. In order to further improve the treatment of proximal humerus fractures and decrease the rate of fixation failures, further research is necessary. As a first step, the reasons for potential implant failures need to be understood. This study has been initiated by scientists at the AO Research Institute Davos (ARI), Switzerland, which is the research center of the AO Foundation (www.aofoundation.org), an international non-profit organization led by surgeons specialized in fractures such as these. Researchers at the ARI have been developing a computational simulation tool to predict fixation failure and demonstrated its efficiency in laboratory conditions. This clinical study has been organised to validate this tool using patient data, by comparing the risk of mechanical failure predicted by the computer simulated model with the clinically observed fixation failure. In future, this computer simulation tool is expected to help surgeons to select the best fixation for a given patient and to develop improved implants.
