Diaphragmatic Rapid Shallow Breathing Index for Predicting Weaning Outcome From Mechanical Ventilation

Predicting successful discontinuation from mechanical ventilation has been a focus of interest to all critical care physicians . Various weaning indices have been investigated to optimize the weaning process. Among them, the rapid shallow breathing index (RSBI) has gained wide use but it have different sensitivities and specificities. By substituting tidal volume (VT) with diaphragmatic displacement (DD) in the calculation of RSBI a new index (the diaphragmatic rapid shallow br...

Acoustic Cardiographic Assessment of Heart Function in Comparison to Doppler-echocardiography

In this study, the investigators sought to determine whether an acoustic cardiographic assessment of heart function is equivalent to Doppler-echocardiography in patients who are treated with cardio-toxic cytostatic agents.

Diaphragmatic Ultrasound Associated With RSBI Predict Weaning Issue: the Rapid Shallow Diaphragmatic Index (RSDI)

The Rapid Shallow Breathing Index (RSBI) is the ratio between respiratory rate (RR) and tidal volume (VT). It is routinely used to predict mechanical ventilation weaning outcome in ICU patients. However RSBI doesn't reflect the muscular contribution of diaphragm or accessory muscles in generating tidal volume. Actually, diaphragmatic dysfunction can even delay weaning process, because accessory muscles are more fatigable than the diaphragm. Hence, we hypothesized that diaphrag...

The study will evaluate the performance of measuring respiration rate with the Respiratory Acoustic Monitoring (RAM).

Acoustic Neuromodulation (ANM) for Youth With Anxiety Disorders

The acoustic neuromodulation trial (ANM-T) is a two-phase, single-site, pilot randomized clinical trial examining the feasibility of completing a larger scale efficacy study of a novel treatment of non-linear modulated acoustic stimuli to reduce anxiety severity in youth with anxiety disorders. The primary objective is to establish the feasibility of a blinded randomized controlled trial of ANM for childhood anxiety disorders.

The Listening Project: Tuning Into Change

A research project funded by the Australian Childhood Foundation (ACF) will be conducted in Australian facilities of the ACF to evaluate the effectiveness of the Listening Project Protocol (LPP) in children with a trauma history. The LPP is designed as a "neural exercise" to reduce auditory hypersensitivities, to improve auditory processing of speech, and to improve behavioral state regulation. The LPP uses acoustic stimulation to exercise the neural regulation of the middle e...

FLACS vs Phaco in Shallow Anterior Chamber

Phacoemulsification in eyes with a shallow anterior chamber (ACD < 2.2mm) presents with problems of safe access to the cataract and increased vulnerability of the endothelium and a higher tendency of complications such as descemet's detachment and iris prolapse. A shallow anterior chamber is also responsible for the high incidence of glaucoma and postoperative complications after cataract surgery. Femtosecond assisted cataract surgery has made cataract surgery safer and more pr...

Diffusion MRI in Heart Failure

The development of symptomatic heart failure is frequently preceded by a pre-clinical period of structural remodeling in the heart. The remodeling process driving this transition, however, remains poorly understood. The investigators hypothesize that imaging the diffusion of water in the heart with MRI will allow its microstructure to be resolved. The investigators further hypothesize that the characterization of microstructural changes in the heart will help elucidate the path...

Efficacy of 68Ga-DOTATOC Positron Emission Tomography (PET) CT in Children and Young Adults With Brain Tumors

This pilot clinical trial studies gallium Ga 68-edotreotide (68Ga-DOTATOC) positron emission tomography (PET)/computed tomography (CT) in finding brain tumors in younger patients. Diagnostic procedures, such as gallium Ga 68-edotreotide PET/CT imaging, may help find and diagnose brain tumors.

Tomography Positron Emission Assessment of the Impact of Cardiac Rehabilitation on Coronary Endothelial Function in Cardiac Failure

In patients with heart failure, the drive to the effort has demonstrated its safety and its interest. Patients with heart failure, endothelium-dependent peripheral vasodilatation is impaired by decreased activity of endothelial NO synthase. The rehabilitation training significantly improves peripheral endothelial function, and this improvement is correlated to the increase in exercise capacity. The impact on coronary endothelial function remains poorly documented, especially in...

Soliton Planar Acoustic Wave Device System for Dermal Clearing Human Trial Protocol

Study of new acoustic wave device as an accessory to laser treatment in tattoo reduction.

Computerized Guideline in Heart Failure: Implementation Process and Impact Evaluation

Objective: To assess the effectiveness of implementation process of an electronic Heart Failure guideline in primary care in the city of Barcelona.

Obesity Related Heart Failure Study

Obesity is a major risk factor for Heart Failure. During this study, we will define the metabolic profile (energy usage) of the heart in the population of obesity related heart failure. To do this, we will be using radioactive materials and a PET (positron emission Tomography)scan to study the metabolism of the heart. Hypothesis- Patients with obesity related HF have a myocardial metabolic profile that is similar to that of obese subjects without heart failure and different ...

Upper Airways in Pregnancy: Evaluation by the Acoustic Reflection Method

It is well known that airway management can be difficult during pregnancy. Increased risks for difficult intubation in pregnant women have been often reported. Thus, pregnancy is regarded as a period of high anesthesiologic risk. Generalized weight gain is a well known factor influencing the upper airway in pregnant women. However, the modifications of the airway itself are less well documented. The acoustic reflection method is based on the analysis of the reflection of a si...

Using Ultrasound Elastography to Predict Development of SOS

Sinusoidal obstruction syndrome (SOS) is a potentially fatal hepatic veno-occlusive disease-affecting children following bone marrow transplantation (BMT). SOS most likely develops secondary to sinusoidal endothelial damage and subsequent obstruction. The disease can be separated into mild, moderate, and severe forms; almost all patients diagnosed with severe SOS will die from this disease. Children with severe SOS suffer from multi-organ failure with signs and symptoms of port...

Hearing Aid Impact on Chronic Tinnitus Patients Evaluated by Resting State PET.

Using resting state positron emission tomography (PET), our goal was to analyze the metabolic and functional neural changes that occur after 6 months of effective hearing aid (HA) use. Besides, we correlate those changes with behavioral results. Patients with chronic tinnitus and untreated sensorineural hearing loss were tested pre-HA fitting, and at 6 months post-HA fitting.
