NCT ID: NCT02801994 Completed - Dyspnea Clinical Trials

Impact of Proportional Assisted Ventilation on Dyspnea and Asynchrony in Mechanically Ventilated Patients

DYS-PAV
Start date: February 24, 2016
Phase: N/A
Study type: Interventional

Rational. The mismatch between the activity of the respiratory muscles and the assistance delivered by the ventilator results in patient-ventilator disharmony, which is commonly observed in ICU patients and is associated with dyspnea and patient-ventilator asynchrony. Both dyspnea and asynchrony are in turn associated with a worse prognosis. Unlike conventional modes of mechanical ventilation, such as pressure support ventilation (PSV) that deliver a constant level of assistance regardless of the patient effort, Proportional Assisted Ventilation (PAV) adjusts the level of ventilator assistance to the activity of respiratory muscles. To date, data on the impact of PAV on dyspnea and patient ventilator asynchrony are scarce and most studies have been conducted in healthy subjects or in ICU patients who had no severe dyspnea nor severe asynchrony. To our knowledge, there are no data in patients with severe patient-ventilator dysharmony. Study Aim. To evaluate the impact of PAV on dyspnea and patient-ventilator asynchrony in ICU mechanically ventilated patients in intensive care with severe patient-ventilator disharmony defined as either severe dyspnea or severe patient-ventilator asynchrony. Patients and Methods. Will be included 24 ICU mechanically ventilated patient exhibiting severe patient-ventilator dysharmony with PSV. The intensity of dyspnea will be assessed by the VAS, the ICRDOSS and by the electromyogram of extradiaphragmatic inspiratory muscles and pre inspiratory potential collected from the electroencephalogram. The prevalence of patient-ventilator asynchrony will be quantified. Expected results. It is anticipated that the switch from PSV to PAV will decrease the prevalence and severity of dyspnea and the prevalence of patient-ventilator asynchrony.

NCT ID: NCT02801838 Completed - Dyspnea Clinical Trials

Validation of an Observational Scale of Dyspnea in Non-communicating Patients in the ICU

DYS-NOC
Start date: February 23, 2016
Phase: N/A
Study type: Interventional

Background : Dyspnea is common and severely impact mechanically ventilated patients outcomes in intensive care unit (ICU). Recognize, measure and treat dyspnea have become current major therapeutic challenge. Its measurement involves a self-assessment by the patient, and by definition, a certain level of communication. Consequently, a large proportion of the ICU-population (non-communicating) misses its evaluation and potential benefits associated with its control. In other hand, electrophysiological markers that help to detect and quantify dyspnea regardless of the patient's cooperation, has been developed and validated as dyspnea surrogate, namely: 1) the electromyographic (EMG) activity of extra diaphragmatic inspiratory muscles and 2) the premotor inspiratory potentials (PIP) detected on the electroencephalogram (EEG). Because of its complex implementation in daily practice the research team has developed alternatively a behavioral score called IC-RDOS that provides reliable dyspnea assessment also without patient participation. Validated in conscious patients, it has not been yet validated in non-communicating patients. Hypothesis : The IC-RDOS is valid for non-communicating ventilated patients and allows a simple and reliable assessment of dyspnea in this specific population. Objective : To validate the IC-RDOS in non-communicating ICU patients under mechanical ventilation, using comparison with the tools validated for reliable measure of dyspnea in non-communicating patients (EMG, EEG). Patients and Methods: In 40 patients will be collected simultaneously IC-RDOS, PIP (EEG) and electromyographic activity of three extra diaphragmatic inspiratory muscles (scalene, parasternal and Alae nasi) before and after intervention therapy aiming at reduce dyspnea (ventilator settings or pharmacological intervention), initiated by the clinician in charge of the patient. Expected results : Observe a strong positive correlation between the IC-RDOS and electrophysiological markers (amplitude of the electromyogram and presence and magnitude of PIP). Observe a correlation between changes in the IC-RDOS and the electrophysiological markers after therapeutic interventions. Optimizing patient comfort is a prominent concern in the ICU. By optimizing the detection and quantification of dyspnea in non-communicating patients, this study should ultimately improve the management and "the better living" of ventilated patients in intensive care

NCT ID: NCT02801695 Completed - Pregnancy Clinical Trials

Evaluation of the Efficacy of Citrulline Supplementation on the Delay of Delivery for Women Hospitalized for Pre-eclampsia (CITRUPE)

CITRUPE
Start date: February 20, 2017
Phase: Phase 2/Phase 3
Study type: Interventional

Pre-eclampsia (PE) complicates 2-8 % of pregnancies and is associated with high maternal and fetal morbidity and mortality. The early clinical manifestations are the occurrence of a maternal blood pressure and proteinuria. Placental dysfunction impairs the nutrient supply to the fetus, and may be the cause of an intrauterine growth retardation (IUGR). This is a disease that causes prematurity and currently the only known cure is delivery of the placenta. Nitrogen monoxide (NO) regulates the placental blood flow. However, pre-eclampsia is directly related to a failure of placental NO production. In this context, several clinical trials have tested the effect of NO donors such as L- arginine. However, supplementation with L -Arginine in a randomized trial in Nantes, has proved to be ineffective in severe vascular IUGR. Citrulline is a natural aminoacid precursor to arginine and in contrast to L-arginine escapes uptake in the liver and appears directly in the peripheral blood converted by the kidney in arginine, released into the systemic circulation, Citrulline may therefore be more effective in the treatment of pre-eclampsia. This prospective, randomized, comparative and double-blinded study aims to prolong pregnancy for patients with pre-eclampsia before 36 weeks.

NCT ID: NCT02800954 Completed - Multiple Myeloma Clinical Trials

Value of Macrophage-Colony Stimulating Factor as a New Marker of Bone Lesions in Multiple Myeloma

MCSF-MYELOME
Start date: February 23, 2009
Phase: N/A
Study type: Interventional

The Primary objective of this study is to compare serum levels of Macrophage-Colony Stimulating Factor (M-CSF) in a population of patients with multiple myeloma (MM), in a population of patients with Monoclonal Gammopathy of Undetermined Significance (MGUS) and in a control population.

NCT ID: NCT02800941 Completed - Clinical trials for Pulmonary Arterial Hypertension

Bleeding Frequency Under Anticoagulant Treatment in Pulmonary Hypertension

HEMA-HTP
Start date: July 5, 2017
Phase:
Study type: Observational

Pulmonary hypertension (PHT) patients often receive long term oral anticoagulants. If the indication is strong, in the secondary chronic thrombo-embolism pulmonary hypertension (CTE-PHT) prevention, the frequent prescription (50 to 90% of patients) contrasts with their low level of proof in the PHT. Last but not least, anticoagulants are known to be the principal cause of iatrogenic hospitalization (major bleeding). In this study, patients are all followed during one year, to determine the annual frequency of major bleedings (according to the International Society on Thrombosis and Haemostasis (ISTH) international definition). Each event notified is validated by an independent committee for clinical events.

NCT ID: NCT02800642 Completed - Clinical trials for Central Retinal Vein Occlusion

Evaluation of a Treat and Extend Regimen of Intravitreal Aflibercept for Macular Edema Secondary to CRVO

CENTERA
Start date: June 10, 2016
Phase: Phase 4
Study type: Interventional

Central retinal vein occlusion (CRVO) occurs when the main blood vessel that transports blood away from the retina (the very back portion of the eye) becomes blocked, causing the leakage of fluid into the retina and thereby causing a swelling of the macula (the portion of the retina responsible for fine vision). This swelling is called macular edema. When the macula swells with fluid, central vision becomes blurry. The study drug aflibercept has been shown to reduce the amount of fluid and blood leaked into the retina. It can help to stabilize, and in many cases, improve the vision loss related to CRVO. Aflibercept has been approved for the treatment of macular edema secondary to CRVO in the United States (US), European Union (EU), Japan, and other countries. The study was considered research because, although the study drug was already on the market for macular edema secondary to CRVO, there were no studies available that addressed the questions of what were useful intervals for treating and assessing patients, how did they differ among patients, and how were criteria applied for retreatment. The purpose of this study was to evaluate the effectiveness, treatment interval, and safety of the treatment regimen (pattern for administering treatment) in subjects with macular edema secondary to CRVO. In addition, this study explored new imaging methods for assessing the affected eye.

NCT ID: NCT02800434 Completed - Amputation Clinical Trials

Clinical Evaluation of Bilateral Hand Allograft: Pilot Study of 7 Cases

Start date: January 2000
Phase: N/A
Study type: Interventional

The double amputation of the forearms is a rare handicap that seriously impacts the autonomy and the quality of life of patients, social and familial exclusion, and dependence on third parties for everyday activities. The management of these patients is nearly exclusively through the use of prostheses. Certain patients refuse this solution, or remain penalized by the absence of sensation, the lack of precision in movements, and body image issues related to the amputation; the double graft of hands and forearms may, in this circumstance, be the only solution. The objective of this pilot study was designed to evaluate the cerebral plasticity of patients who undergo bilateral hand allograph

NCT ID: NCT02799901 Completed - Melanoma Clinical Trials

Nivolumab Plus Radiotherapy in Advanced Melanoma

NIRVANA
Start date: March 3, 2017
Phase: Phase 2
Study type: Interventional

Combining nivolumab with conventional multisite high dose radiotherapy seems to be an interesting approach that could increase the antitumoral effect of nivolumab by increasing the diversity and quantity of tumoral antigen presentation thanks to radiotherapy. Multifractionated high dose radiotherapy (HR) targeting various tumor sites could also increase occurrence of tumor mutations and the diversity of the T-cell receptor repertoire of intratumoral T cells. The purpose of this study is to combine nivolumab with 3 fractions of HR of one metastasis for each tumor site (defined as skin/muscle, thoracic, abdomen, bone, other). The investigators hypothesize that combining nivolumab with multisite, multifractionated HR increases the overall survival rate at 1 year compared to published data with nivolumab alone.
