NCT ID: NCT02267252 Recruiting - Sperm Antibodies Clinical Trials

Effects of Male-specific Antibodies on Sex Ratio

Start date: September 2014
Phase:
Study type: Observational

Investigation of the ability of antibodies from vasectomized men in binding to Y-spermatozoa as a possible explanation of the lower sex ratio observed after microinsemination using epididymal sperm from vasectomized men.

NCT ID: NCT02265770 Recruiting - Clinical trials for Childhood Ependymoma

An International Clinical Program for the Diagnosis and Treatment of Children With Ependymoma

SIOP-EP-II
Start date: June 2, 2015
Phase: Phase 2/Phase 3
Study type: Interventional

The overall aim of this project is to improve the outcome of patients diagnosed with ependymoma by improving and harmonising the staging and the standard of care of this patient population and to improve the investigators understanding of the underlying biology thereby informing future treatment. The program will evaluate new strategies for diagnosis (centralized reviews of pathology and imaging) and new therapeutic strategies in order to develop treatment recommendations. Patients will be stratified into different treatment subgroups according to their age, the tumour location and the outcome of the initial surgery. Each subgroup will be studied in a specific randomised study to evaluate the proposed therapeutic strategies. Stratum 1: The aim of the stratum 1 is to evaluate the clinical impact of 16-week chemotherapy regimen with VEC-CDDP following surgical resection and conformal radiotherapy in terms of progression free survival in patients who are > 12 months and < 22 years at diagnosis, with completely removed intra cranial Ependymoma. Stratum 2: This stratum is designed as a phase II trial for patients who are > 12 months and < 22 years at diagnosis, with residual disease to investigate the possible activity of HD-MTX by giving to all patients the benefit of VEC chemotherapy whilst randomising half of patients to receive additional HD-MTX. Patients will receive conformal radiotherapy (cRT). For patients who remain with a residual inoperable disease after induction chemotherapy and cRT, an 8 Gy boost of radiotherapy to the residual tumour will be delivered immediately after the end of the cRT. Stratum 3 This stratum is designed as a phase II trial to evaluate the benefit of postoperative dose intense chemotherapy administered alone or in combination with valproate in children <12 months of age or those not eligible to receive radiotherapy .

NCT ID: NCT02246257 Recruiting - Clinical trials for Cardiovascular Diseases

Early Rheumatoid Arthritis COR Intervention

ERACORI
Start date: September 2014
Phase: N/A
Study type: Interventional

The primary aim of our present study is to evaluate the effect of a targeted, intensified, multidimensional intervention compared to conventional treatment of modifiable risk factors for CVD in patients with early RA. The primary endpoint, a composite of death from cardiovascular causes, non-fatal MI, non-fatal stroke and re-vascularisation, will be assessed after 5years' follow-up.

NCT ID: NCT02234804 Recruiting - Coronary Disease Clinical Trials

The Does Optical Coherence Tomography Optimize Revascularization (DOCTOR) Recross Study

DOCTOR Recross
Start date: July 2013
Phase: N/A
Study type: Interventional

Prospective, controlled, double randomized, non-blinded, multicenter, investigator initiated, academic superiority trial comparing optical coherence tomography (OCT) guided vs. angiography guided wire recrossing in jailed side branches (SB) (1. randomization 1:1)(superiority) and comparing Medtronic Resolute Integrity and Xience Prime for stent strut apposition in the SB ostium (2. randomization 1:1) (superiority). Acute primary endpoint and 30 days clinical follow-up. Hypothesis: OCT guided wire recrossing in bifurcation stenting results in less malapposed struts in the segment facing the SB ostium. Secondary hypothesis: Treatment by Medtronic Resolute Integrity stent results in less malapposed struts at the bifurcation segment compared to treatment by the Abbott Xience Prime stent.

NCT ID: NCT02230865 Recruiting - Postoperative Pain Clinical Trials

Prediction of Acute Postoperative Pain and Analgesic Consumption

MIRPEX-3
Start date: August 2014
Phase: N/A
Study type: Observational

Pain is an expected part of surgical recovery but effective pain management remains challenging. The high variability in postoperative pain experience and analgesic treatment response between patients is part of the challenge. Few studies have yet combined preoperative assessment of responses to experimental pain with measurements of cognitive and emotional processes in the prediction of postoperative pain. We hypothesize, that preoperative evoked brain potentials (using standard electroencephalographic brain imaging), endogenous pain inhibition capacity (conditioned pain modulation), responses to pressure/thermal pain stimulation, and/or situational pain-related catastrophic thinking are useful clinical predictors of postoperative pain and analgesic consumption.

NCT ID: NCT02226328 Recruiting - Sedation Clinical Trials

Nurse Administered Propofol Sedation vs. Midazolam With Fentanyl-sedation for Flexible Bronchoscopy: A Randomized, Single Blind, Controlled Study of Satisfaction and Safety.

Start date: November 2014
Phase: Phase 4
Study type: Interventional

Flexible bronchoscopy almost always requires sedation to be successful. In order to increase the availability of propofol for sedation, non-anaesthesiologist administered propofol sedation has been suggested as an alternative to traditional midazolam/opioid sedation or the general anaesthesia provided by anaesthesiologists. Hypothesis: Patients undergoing flexible bronchoscopy prefers non-anaesthesiologist administered sedation with propofol as opposed to non-anaesthesiologist administered sedation with midazolam and fentanyl. Propofol sedation is as safe as midazolam and fentanyl sedation.

NCT ID: NCT02217072 Recruiting - Learning Problems Clinical Trials

Educational Support Interventions for Children in Care

Start date: September 2013
Phase: N/A
Study type: Interventional

A Randomized controlled study of two different educational support interventions developed for children in foster care (age 6-13).

NCT ID: NCT02215603 Recruiting - Prolonged Sitting Clinical Trials

Effects of Disrupting Prolonged Sitting With Different Physical Activity Protocols on Metabolic Risk Factors in Sedentary Adults

Start date: August 2014
Phase: N/A
Study type: Interventional

Great controversy exists with respect to the optimal or the minimum volume, intensity, and frequency of physical activity capable of attenuating the hazards of prolonged sitting on the metabolic profile. Thus, our study aims to comprehensively investigate the effects of disrupting prolonged sitting with different physical activity protocols on metabolic risk factors in sedentary males. Ten sedentary males will take part in this randomized cross-over trial consisting of four 27-h conditions. All conditions will be identical except for the physical activity: prolonged sitting intervention (SIT) participants will sit continuously for 9 hours; prolonged sitting+interval standing intervention (STAND), participants will stand for 15 min every 30 minutes (total 270 min) during the 9 hours of sitting; prolonged sitting+moderate-intensity exercise bout (MVPA) participants will perform a 30-min moderate-intensity exercise bout on a treadmill (energy-matched to STAND), after which they will sit for the remaining time; and prolonged sitting+moderate-intensity exercise bout +interval standing intervention (MVPA-STAND), participants will perform a 30-min moderate-intensity exercise bout on a treadmill (energy-matched to STAND), after which they will stand for 15 min every 30 minutes (total 240 min) during the remaining 8 hours of sitting. Blood glucose, insulin, lipids and cytokines will be determined. The investigators expect that disrupting prolonged sitting with intermittent standing and a moderate-exercise bout will positively affect the metabolic profile of the participants. Furthermore, we will investigate if combined, these strategies will have an additive effect.

NCT ID: NCT02215577 Recruiting - Colorectal Cancer Clinical Trials

ALPPS Versus PVE/PL

LIGRO
Start date: June 2014
Phase: N/A
Study type: Interventional

Study Title Comparison of two different models of liver growth stimulation in advanced colorectal liver metastatic disease, (LIGRO Trial) enabling liver resection Methodology Scandinavian Multiple Center Randomized Registry Based Clinical Trial Study duration The planned duration of study participation for an individual subject from inclusion to follow-up are 3 years Primary investigator: Per Sandstrom (Linköping) Number of subjects 100 patients randomized in a 1:1 randomization Diagnosis and main inclusion criteria Patients with colorectal liver metastasis requiring liver resection, but are not resectable in one step because of a future liver remnant/standardized total liver volume of < 30 % extrahepatic metastatic disease is not an exclusion criteria if they can be addressed surgically in the future Overall goal To evaluate if the ALPPS approach is superior to PVE in enabling patients, primarily unresectable due to inadequate FLR, to be resected and reach an R0 situation with an acceptable level of complications and perioperative mortality. To evaluate if the ALPPS approach increases the growth rate of the liver compared to portal embolization or portal ligation leading to a shorter treatment period. In addition the investigators aim to study if ALPPS may reach these goals without detectable or improved differences in tumor activity (PFS and OS), but with a shorter recovery and a higher proportion of patients reaching R0. Hypothesis A higher proportion of patients can be resected with ALPPS counted as rate resected compared to the previously established methods with portal ligation or embolization. This increased resection rate will not reduce the R0 rate, or increase the rate of Clavien grade 4 complication or higher (H0). The ALPPS approach will increase the growth rate compared to portal embolization/ligation measured one week after the primary intervention.

NCT ID: NCT02202486 Recruiting - Chronic Migraine Clinical Trials

Investigation of the Blood-brain and Blood-dura Barrier Durin Migraine Attacks Using MRI

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

Substudy 1 Blood-brain barrier breakdown has been proposed in migraine patients. Our hypothesis that we will test in this study is that the blood-brain barrier breaks down during migraine attacks but not out side attacks using MRI. Substudy 2 Altered cerebral resting-state functional connectivity networks have been reported in migraine patients outside migraine attacks. What happens during migraine attacks has never been investigated. The hypothesis we will test is that pain related networks are affected during spontaneous attacks using functional MRI. Substudy 3 Old studies report that cerebral blood flow (CBF) is altered in patients with migraine with aura, but not in those without aura. We hypothesize that CBF is altered regionally during attacks, which we will investigate in this study using arterial spin labeling (ASL). Substudy 4 Structural changes using voxel-based morphometry (VBM) of the brain have been suggested but never investigated during migraine attacks. Our hypothesis is that pain related structures show altered VBM during spontaneous migraine attacks.
