Filter by:Aneurysms of the thoracic ascending aorta are a serious pathology which may threatens life by rupture or dissection. Their incidence is estimated at 10.4 per 100,000 people. At present, the only parameter for assessing the risk of complication is the maximum diameter of the aneurysm. The only way to avoid a complication is a surgical replacement of the aneurysmal aorta by a prosthetic tube. This procedure is performed by sternotomy and with extracorporeal circulation and its death rate ranges between 3% and 5%. Surgical repair is indicated when the diameter of the aneurysm exceeds 5.5 cm for degenerative atheromatous aneurysms or 5 cm in a patient with genetic disorder of connective tissue (Marfan disease or Ehlers-Danlos syndrome). However, there are aneurysms with diameter greater than the surgical threshold which remain stable. Conversely, complications have been described for aneurysms less than 4.5 cm in diameter. The criterion of diameter appears therefore as inadequate to assess the risk of complication of an aneurysm of the ascending aorta.Multiple methods have been described in the literature. One of them relies on in vitro mechanical testing on healthy or aneurysmal tissue. Another method is the vivo analysis from imaging (CT, MRI or ultrasound). So far, no algorithm is robust enough for predicting the risk of complication better than the universally used criterion of diameter. The pathophysiology of these aneurysms has also been explored from histological studies. The investigators know that the microstructure of the aortic wall of an aneurysm is deteriorated with a degradation of elastin fibers and collagen that determine to a large extent its biomechanical behavior. Histological analysis appears inseparable from biomechanical analysis.
The purpose of this study is to determine whether fluoride supplementation during pregnancy is effective in extending the length of gestation and improving overall perinatal well-being.
The aim of this study is validate the use of biopolymer from sugar cane molasses film (POLYSHAFT®) a product developed in Experimental Station research laboratories (UFRPE) comparing to polyurethane film, or similar, used as a bandage after surgical correction of hypospadias, as well as other procedures. The main objective of the study is to prove the hypothesis the POLYSHAFT® presents similar or better outcomes in terms of biocompatibility, when compared to the polyurethane film when used as a bandage.
Introduction This study will evaluate the effect on glucose, lipid and bone metabolism following conservative orthopaedic procedures in patients who suffered from acute Achilles tendon rupture. The sedentary rehabilitation period following these procedures may impact negatively upon glucose, lipid and bone metabolic pathways whereas the more physically active rehabilitation period instituted 8 weeks after the injury is hypothesized to impose positive metabolic effects. The study is addition to the on-going clinical trial, Non-operative Treatment of Acute Achilles Tendon Rupture: Early Controlled Mobilization Compared With Immobilization, ClinicalTrials.gov Identifier: NCT02015364. Perspective This study will establish whether the well-known effects on glucose, lipid and bone metabolism of a sedentary lifestyle can be observed already following 8 weeks of almost total abstain from physical activity in non-diabetic individuals, who suffered an acute Achilles tendon rupture. Thereby, we will add knowledge to the previous findings following strict bed-rest in healthy individuals on glucose and lipid metabolism and bone turnover. In a clinical perspective it is important to examine the extent to which individuals deteriorate in various metabolic pathways to better understand the pathophysiology behind these defects both in healthy individuals and in patients, who undergo bed rest or an equal reduction in physical activity as part of their rehabilitation. Study design The present study includes 50 cases, who are examined early following injury (< 2 weeks) (baseline), 8 weeks (6 - 10 weeks) after injury and 52 weeks (40 - 64 weeks) after injury, respectively. Oral glucose tolerance test (OGTT) with ingestion of 75 g of glucose during a maximum of 3 min from baseline (0 min). Plasma for glucose, insulin, C-peptide, NEFA will be drawn. The individual will bring in morning spot urine for measurement of suPAR, creatinine, albumin and orosomucoid. The individual will have drawn blood for measurement of HbA1c, total cholesterol, LDL cholesterol, HDL cholesterol, triglyceride, Na, K, creatinine, HgB, CRP, leukocytes, ALAT, alkaline phosphatase, Ca++, D vitamin, TSH, albumine and amylase. Also blood for BTM and plasma suPAR, IL6, TNFa and hsCRP will be drawn. Finally blood for lipid density profiling and lipid particle size will be drawn DXA of hip and lumbar spine including abdominal visceral and subcutaneous fat is done on a Hologic Discovery scanner.
Early rehabilitation after anterior cruciate ligament reconstruction is of paramount importance and requires optimal pain control based on a multimodal concept, including injection of local anaesthetics. Regarding this latter, different options have emerged recently such as the adductor canal block, performed before the surgery by the anaesthesiologist or the infiltration of the articulation performed by the surgeon at the of the intervention. No trial has compared these two approaches. As practice of medicine should be based on evidence, we decided to undertake this randomised controlled trial where we compared the adductor canal block with the local infiltration analgesia technique in terms of pain and functional outcomes
In this study we will examine patients who have undergone anterior cruciate and/or posterior cruciate ligament and/or multi ligaments reconstruction to determine the rate of re-injury, contralateral tear and functional outcomes at least two years after surgery.
Anterior cruciate ligament (ACR) rupture is a common lesion of sportsmen that leads to functional deficits which are difficult to overcome. To prevent from an unfavorable evolution, patients can either get a non-surgical treatment or an ACR surgery, which is very common. Knee functional performance level could impact on the postoperative outcome and it's of common knowledge that early re-education after an ACR rupture improves knee functioning. Patients with an ACR rupture enrolled in this study will be randomized either in an experimental group (with preoperative reeducation) or in a control group (without preoperative reeducation). Both groups will then have post-operative re-education (40 sessions) based on HAS recommendations. The main aim of this study is to assess the impact of preoperative re-education on knee functional performance 4 month after surgical reconstruction of an ACR. Secondary aims are to determine the impact of the 4-week preoperative re-education on knee functional performance after an ACR rupture, before surgery and 7 months after surgery. Functional performance, muscular strength, proprioception and anterior knee laxity will be measured at inclusion (V0), 4-5 days before surgery (V1), 4 month (V4M) and 7 months (V7M) after surgery. Lysholme-Tegner scoring and IKDC2000 questionnaire will be added to the previous assessments.
Distal biceps ruptures occur most commonly among young males in their third and fourth decade of life. These injuries are becoming more common, however, as the aging population is remaining active through sport or labour demands. Distal biceps tears or ruptures follow a heavy eccentric load being placed on a shortened or flexed muscle, and often require surgical repair. Functionally, distal biceps injuries cause impairment as this portion of the muscle is largely responsible for supination and flexion at the elbow. Currently there is no consensus regarding post-operative immobilization protocols, and little evidence is available regarding timeframe for early return to functional activities. Existing evidence on functional outcomes post distal biceps tendon repair (DBTR) is of low quality with small sample sizes, and no known RCTs exist comparing early mobilization to immobilization on functional return. Reported timeframes for immobilization range from early controlled motion on day 1 post-operatively to complete immobilization for 6 weeks. The primary study goal is to determine the effect of immobilization compared to unrestricted mobility post DBTR on early functional return to activities. It has been previously reported that those with DBTR related to a workers compensation injury returned to full duties in 3.95 months, while those with a non-workers compensation related injury returned to full work duties in 1.35 months. In Alberta, near 100 WCB claims were made for DBTR in both 2013 and 2014. Early mobilization of these repairs may allow an earlier return to modified and full work duties, thereby improving the functional quality of life of the individual as well as reducing the overall cost of disability payments. This study will assess the 1) time to return to pre-injury work level and 2) time to return to modified duties among those who have no movement restriction post-repair and those who are splinted for 6 weeks. Re-rupture rates between groups will also be assessed as will strength, range of motion (ROM) and quality of life. These findings will assist in developing a standardized protocol for immobilization to optimize functional and clinical outcomes while expediting return to work.
The purpose of this study is to validate a practical risk score to predict the mechanical complication of ST-elevation myocardial infarction (STEMI).
Autologous adipose-derived regenerative cells (ADRC) will be extracted using Celution 800/CRS System (Cytori Therapeutics Inc) from a portion of the fat harvested from the patient's front abdominal wall. Patients will undergo knee arthroscopic surgery followed by one-time intraarticular ADRC administration (directly into anterior cruciate ligament). This is a single arm study with no control. All patients receive cell therapy.
