NCT ID: NCT01664234 Completed - Difficult Airway Clinical Trials

Oxygen Insuflation and ArterialDesaturation During Tracheal Intubation in Children

Start date: January 1, 2012
Phase: N/A
Study type: Interventional

Infants (0-1 yr.) with anticipated difficult airways will be enrolled in the study. Specifically, we will include infants with cleft palate, Pierre Robin, Treacher Collins, trisomy 21, or similar congenital malformations. Patients with American Society of Anesthesiologists physical status scores ≥3 will be excluded, as will those with congenital heart disease and left-to-right shunting. Patients will be randomly assigned to laryngoscopy with or without simultaneous insufflation of oxygen at 4 L/minute. Oxygen will be provided by a flowmeter connected via rigid tubing to the track-mounted endotracheal tube on the AirTraq. Randomization (1:1) will be based on computer-generated codes with random block sizes and stratified by hospital; allocation will be concealed and provided to clinicians via a secure web site that will be accessed shortly before induction of anesthesia.

NCT ID: NCT01663883 Completed - Clinical trials for Decreased Vascular Flow

Optic Nerve Head Autoregulation During Changes in Arterial Blood Pressure

Start date: February 2012
Phase: N/A
Study type: Interventional

Constant despite changes in perfusion pressure. It is observed in many vascular beds of the human body to prevent that variations in perfusion pressure are directly transmitted into changes in blood flow. This is necessary to prevent ischemia and/or hypoxia during decreased blood flow and bleeding or increased capillary pressure during increased blood flow. In the eye, several studies have reported that retinal blood flow is autoregulated over a wide range of ocular perfusion pressures. Unfortunately only few data are available for the optic nerve head. To gain data about autoregulation is of special importance given that several important ocular diseases such as glaucoma and age-related macular degeneration are associated with impaired autoregulation. In humans most data were collected using laser Doppler flowmetry. The present study aims to investigate the phenomenon of transient reduction in blood flow and to gain insight in the regulatory mechanisms of optic nerve head blood flow during isometric exercise.

NCT ID: NCT01663597 Completed - Refractive Errors Clinical Trials

Optical Biometry and Spherical Aberration in Ametropic and Emmetropic Eyes

Start date: August 2012
Phase: N/A
Study type: Observational

Aberrations play a significant role in the visual process and can be divided in lower-order and higher-order aberrations. The former can be measured using the commercially available IOL Master (Carl Zeiss Meditec AG, Germany) and have profound influence on visual acuity. Higher-order aberrations do not significantly influence visual acuity but affect the quality of vision and can cause halos, double vision, and night vision disturbances. Background Cataract surgery has become a routine procedure in the developed countries. During this surgery, a foldable intraocular lens is usually inserted into the capsular bag. However, these lenses do not account for individual optical biometry data or aberrations. Therefore, it is important to provide data for ametropic and emmetropic eyes as this information might improve future intraocular lens design and lead to individually adapted lenses for yielding optimal visual acuity and quality results. The aim of the present study is to clarify the correlation between refractive errors/axial eye length and spherical aberrations of the cornea.

NCT ID: NCT01663402 Completed - Clinical trials for Atherosclerotic Cardiovascular Disease

ODYSSEY Outcomes: Evaluation of Cardiovascular Outcomes After an Acute Coronary Syndrome During Treatment With Alirocumab

Start date: October 2012
Phase: Phase 3
Study type: Interventional

Primary Objective: To compare the effect of alirocumab with placebo on the occurrence of cardiovascular (CV) events (composite endpoint of coronary heart disease (CHD) death, non-fatal myocardial infarction (MI), fatal and non-fatal ischemic stroke, unstable angina (UA) requiring hospitalization) in participants who experienced an acute coronary syndrome (ACS) event 4 to 52 weeks prior to randomization and were treated with evidence-based medical and dietary management of dyslipidemia. Secondary Objectives: - To evaluate the effect of alirocumab on secondary endpoints (any CHD event , major CHD event, any CV event, composite of all cause mortality/non-fatal MI/non-fatal ischemic stroke, CHD deaths, CV deaths, all cause mortality). - To evaluate the safety and tolerability of alirocumab. - To evaluate the effect of alirocumab on lipid parameters.

NCT ID: NCT01663181 Completed - Clinical trials for Urinary Incontinence

Pain-perception During Outpatient cystoscopy-a Prospective Controlled Study

Start date: May 2009
Phase:
Study type: Observational

At an academic tertiary referral center, patients with pelvic floor dysfunction, scheduled for outpatient cystoscopy or urodynamic testing will be asked to participate in the study. Patients will be called one day after the examination and will be asked about pain and their general state of health. The purpose of this study it to investigate pain perception in urogynecologic patients during outpatient cystoscopy and compare it with pain perception during outpatient urodynamic. The investigators will also investigate the difference between anticipated and actual pain perception. The investigators will test the null hypothesis that there is no difference in patients´ pain perception between outpatient cystoscopy and urodynamic testing. The secondary hypothesis will be that there is no difference between patients´ anticipated amount of pain and the actually experienced pain during cystoscopy and urodynamic testing. According to power calculation, a sample size of 52 patients per group will be needed to detect a 2 cm difference in pain scores on the VAS - judged as a clinically significant difference - with 95% power and a two-sided significance level of 0.05. Exclusion criteria are: age ≤ 18 years, insufficient ability to understand German, pregnancy and the participation in another clinical study at the same time.

NCT ID: NCT01660490 Completed - Clinical trials for Proximal Femur Fractures

Development and Validation of Intraoperative Image-quality Criteria

Start date: September 2012
Phase: N/A
Study type: Observational

An expert panel of surgeons agreed that there is not any established, standardized approach to the teaching of intraoperative imaging and that there may be practice gaps in decision making and the use of imaging among trauma surgeons. The panel is set to initiate a consensus-based evaluation process to develop a list of criteria for assessing images and would like to validate these criteria for differentiating good quality versus poor quality images in term of reliability and accuracy.

NCT ID: NCT01660451 Completed - Clinical trials for Lymphoma, Non-Hodgkin

Open-label, Uncontrolled Phase II Trial of Intravenous PI3K Inhibitor BAY80-6946 in Patients With Relapsed, Indolent or Aggressive Non-Hodgkin's Lymphomas

Start date: November 19, 2012
Phase: Phase 2
Study type: Interventional

The objective of the study (part A) is to evaluate the efficacy and safety of BAY80-6946 in patients with indolent or aggressive Non-Hodgkin's Lymphoma, who have progressed after standard therapy. 30 patients will be enrolled to both indolent and aggressive disease group. The objective of the study part B (CHRONOS-1) is to evaluate the efficacy and safety of BAY80-6946 in patients with relapsed/refractory follicular lymphoma. 120 patients will be enrolled in the part B of the study. Further objectives are to evaluate the pharmacokinetics and biomarkers. Quality of life will be a further objective of part B of the study. In a cohort of 20 patients (enrolled both in part A and B) an ECG substudy will be performed to assess the potential for cardiac toxicity and QT/QTc interval prolongation of BAY80-6946. After an up to 28-day screening period, eligible patients will start treatment with BAY80-6946 at a dose of 0.8 mg/kg (Part A) and at a dose of 60 mg (Part B). Treatment will be continued until disease has progressed or until another criterion is met for withdrawal from study. An end-of-treatment visit will be performed within 7 days after discontinuation of study treatment. Thirty to 35 days after last study drug administration, a safety followup visit will be performed for the collection of adverse events (AEs) and concomitant medication data. Patients will be contacted quarterly to determine overall survival status up to 4 years after last patient completed treatment. Patients who discontinue study drug for reasons other than disease progression will enter the Active Assessment Follow-up period. The end of study notification to Health Authorities will be based on the completion of the collection of survival data. The efficacy is measured by the decrease in tumor size. Tumor assessments will be done at Screening, every 8 weeks during Year 1, every 12 weeks during Year 2, and every 6 months during Year 3. Blood samples will be collected for pharmacokinetic analysis. Archival tumor tissue and blood samples will be collected for biomarker analysis (mandatory) and for central pathology review (part B), fresh biopsy tissue will also be collected if available.
