INTRODUCTION:
Endovascular aneurysm repair (EVAR) has lower short-term morbidity and mortality than open surgery. Intra-arterial contrast agents are an important component of successful EVAR as the tool of choice for preoperative evaluation of aortic aneurysm morphology as well as precise sizing and
This is a single site, randomized, sham-controlled, double-blind study assessing the feasibility, safety, tolerability, and efficacy of non-invasive VNS (nVNS) in the treatment of headache in subarachnoid hemorrhage (SAH). The hypothesis is that two-two minute noninvasive stimulations of the
The objective of this study is to use the novel approach of neuro-reinforcement based on decoded fMRI information to reduce fear responses to fearful stimuli (e.g., spiders, heights) in individuals with phobias, directly and unconsciously in the brain, without repeatedly exposing participants to
The exact mechanisms by which AMS develops remains poorly understood. Interestingly, brain and spinal cord swelling due to low oxygen levels can also occur in the period following surgery to treat thoracic and abdominal aortic aneurysms, dangerous swellings of the major blood vessel in the body.
The open repair of abdominal aortic aneurysm (AAA) is a painful surgery. Patients suffering from AAA are at high risk of perioperative cardiovascular and pulmonary complications. It has been previously suggested that a bad perioperative pain control could increase the incidence of such

ARTERIAL BLOOD PRESSURE CLASSIFICATION
Arterial Blood Pressure (ABP) is a complex physiological variable in regard to its measure, behavior between BP taken in the same visit at the office and between these and ABPM, chronobiology (different day time BP levels), evolution in time,
If you are eligible to enroll in the study, you will be contacted by the principal investigator in person and he will describe the study in a private setting (neurosurgery clinic room or hospital patient room). You will be given ample opportunity to decide to participate or not.
You will be randomly
CTA infusion is administered using a 5 ml/sec IV iodinated contrast infusion. 50-70 ml of iodinated contrast is used for the scan depending on the patient's body habitus. The total contrast dose must not exceed 70 ml. An automated bolus tracking feature (SmartPrep, GE Healthcare, Milwaukee, USA) is
The proposed study is a randomized, placebo-controlled, triple-blinded, parallel-group clinical trial. Patients will be recruited from the neurosurgical population at St. Michael's Hospital.
The inclusion criteria are:
- Adults aged 18 years and over;
- scheduled for one of the following
H.E.L.P. therapy is indicated for use in treating patients with familial hypercholesterolemia (FH) who have undergone six months of optimal diet and drug therapy and whose LDL-C level remains > 300 mg/dl in the absence of CHD or > 200 mg/dl with documented CHD. These patients are divided into three
Study objective To compare the efficacy of two MO administration-protocols: PCA MO (only) vs combination of continuous background infusion plus PCA MO (combined dosage) in patients after abdominal and thoracic surgery.
Methods Inclusion criteria The study will be conducted as a prospective,
Background
Renal impairment following cardiopulmonary bypass is common. 11.4% (1) to 42% (2) of patients with previously normal renal function show a postoperative rise in serum creatinine. While most of these patients do not require either short or long term renal replacement, the mortality of
