Background: The requirement for ventilator support is a defining feature of critical illness. Weaning is the process during which the work of breathing is transferred from the ventilator back to the patient. Approximately 40% of the total time spent on ventilators is dedicated to weaning. The extent of practice variation in how this complex and expensive technology is discontinued from critically ill patients is unknown. Meanwhile, practice variation has been shown to adversely impact upon patient safety and clinical outcomes. Purpose: To characterize practice pattern variation in weaning and the consequences of weaning variation by implementing an international, prospective observational study in Canada, the United States, the United Kingdom, Europe, India and Australia/New Zealand. Primary Objectives: To describe 1. weaning practice variation among regions in 5 domains (the use of daily screening, preferred methods of support used before initial discontinuation attempts, use of written protocols, preferred methods of evaluating spontaneous breathing, and sedation and mobilization practices). 2. the assocation between selected discontinuation strategies and important clinical outcomes (length of stay, mortality, duration of ventilation). Methods: The investigators propose to conduct a large scale, observational study involving critically ill adults requiring ventilator support for at least 24 hours to evaluate practices in discontinuing ventilators in 150 centres. The investigators will classify each new admission over the observation period according to the initial strategy that precipitated or facilitated ventilator discontinuation. Relevance: This novel study will build collaborations with critical care investigators from around the world and industry
The aim of this study is to explore new safe effective psychotherapeutic interventions for schizophrenia through assessing the efficacy and acceptability of complementary "Insight Enhancement Program" (IEP) and "Metacognitive Training for Psychosis" (MCT), in relation to each other, and in relation to "Treatment As Usual" (TAU). It is hypothesized that at the end of therapy, compared to "Treatment As Usual", patients undergoing whether (IEP) or (MCT) will display a significant reduction in psychopathology particularly positive symptoms and delusional ideation, and a significant improvement in Insight and metacognitive capacity. Additionally, it is hypothesized that the acceptance of (IEP) and (MCT) will be higher than acceptance of (TAU). This study also aims to examine whether metacognition is associated with insight even after controlling for the effects of psychiatric symptomatology.
Objectives: To evaluate the clinical and antimicrobial effect of Diode laser and chemical disinfection in comparison to selective caries removal in management of deep carious lesions. Methods: This study will be carried on 30 patients with an age range of 18 -50 years. The patients will be selected from the outpatient clinics in Faculty of Oral and Dental Medicine, Misr International University. All patients will be randomly divided into 3 equal groups; Control group, Diode laser application with an output power of 0.5 watt group, and Chemical disinfection group. Preoperative clinical assessment and radiographs will be performed before intervention and then the patients will receive their treatment and final restorations. Follow-up with clinical assessments will be performed after 3 and 6 months. Cone beam computed tomography will be performed at the day of intervention and after 6 months. Clinical, Microbiological and Radiographic data will be collected, tabulated and statistically analyzed to compare between the success rates of diode laser, chemical disinfection and conventional selective caries removal.
This study will be conducted as a prospective observational study This study will be done in any of the operating theatres of University Malaya Medical Centre This study will involve paediatric cases ( ages 3-12 years )posted for elective operations which require general anaesthesia with endotracheal intubation Ambu Aura Gain will be used as a conduit for intubation
A prospective comparative study evaluating chest x-ray determination of PICC line tip location and POC ultrasound PICC line tip location. NICU patient's with PICC lines will be enrolled and blinded ultrasound operators will scan the neonate to find the PICC tip location. This will be compared to the location on the patient's chest x-ray. This process will be repeated each time the patient has a chest x-ray.
this study was to evaluate the functional outcome of quadruple hamstring graft in femoral tunnel less than 15 mm and morethan or equal 15 mm of ACL reconstruction. The hypothesize that no difference intermediate follow up ( 6 month - 24 month) of functional outcome and clinical evaluation between short and normal femoral tunnel graft length of hamstring tendon ACL reconstruction.
The recognized manifestations of HHT are all due to abnormalities in vascular structure. Epistaxis are spontaneous, very variable, may occur as often as several times every day, and are recurrent in 90% of patients and associated with chronic and severe anemia in 2-10%. They also significantly reduce quality of life. Blood transfusions are sometimes required in 10-30% of patients. Previous studies showed that antiangiogenic treatments such as anti-VEGF treatment (bevacizumab) administered intravenously was efficient on epistaxis and dramatically reduced nosebleeds. Tyrosine kinase inhibitors are anti-angiogenic molecules which are available orally and could therefore overcome the difficulties encountered with bevacizumab. The investigator hypothesized that nintedanib, acting by indirect inhibition of the VEGF receptor should allow a reduction of epistaxis in HHT patient. Nintedanib has been used in one HHT patient following the diagnosis of Insterstitial Pulmonary Fibrosis (published case report in 2017, Kovacs et al) with encouraging results. The aim is to evaluate efficacy of nintedanib for the treatment of epistaxis in HHT patients
The purpose of this study is to compare the safety and effects of ruxolitinib 1.5% cream with those of standard moisturizers in people with non-sclerotic chronic cutaneous GVHD.
At the completion of orthodontic treatment, the position of the mandibular canines and incisors is being maintained on a routine basis by bonding a multi-braided wire retainer onto their lingual surfaces. One of the adverse events that might occur with time is the debonding of the wire from one or several lower anterior teeth . This event which can unfortunately get unnoticed by the patient can lead to unwanted tooth displacement. When the practionner detects such a debonding, he has to go through a laborious and lengthy procedure to rebond the wire. When on the other hand the patient notices himself such a debonding, he is to call in emergency his practitioner to get his retainer repaired. This leads to emergency visits that are susceptible to affect adversely his timetable. The prevalence of these bonding failures is estimated at 37% at 18 month follow-ups. It has been reported that with prior enamel sandblasting, bonding failure rate is reduced to 8% at 24 month follow-ups. However, no study has reported yet the debonding rate of lower fixed, comparing wires that have been bonded after prior enamel pumicing to those that were put in place after prior enamel sandblasting. The expected result of this trial is a significantly decrease in bonding failure rate of mandibular lingual retainer when enamel surfaces are initially sandblasted compared to the ones which are pumiced. This reduction would lower the risk of unwanted tooth movement of mandibular incisors and canines after orthodontic treatment and decrease the number of emergency appointments for the patient and the practitioner.
