Filter by:The goal of this observational clinical trial is to determine whether the posterior superior iliac spine of the hip or the humerus of the arm will produce larger amounts of bone marrow when harvested during surgery. Also, the secondary goal of this study is to determine the effects of the patient's position on the quantity of cells harvested from the hip, namely lying on back (prone) vs. lying on side (lateral decubitus). The main questions it aims to answer are: - Will the hip or the arm have more bone marrow extracted? - Does a patient lying in lateral decubitus position produce more bone marrow than lying in the prone position? Participants that are to undergo rotator-cuff repair are eligible for this study. During the participant's repair, bone marrow will be extracted from the arm and from the hip. Half of the eligible participants will have bone marrow extracted from the hip while lying on their side, while the other half will have bone marrow extracted from the hip while lying on their back. Researchers will compare the results from both extraction sites on each patient, as well as compare results of the two patient position groups.
Premature rupture of membranes (PROM) at term complicates 6 to 22% of singleton pregnancies. Spontaneous labour occurs in 60-67% of these patients within 24h. If no effective uterine contraction occurs, induction of labour (IOL) is the strategy recommended by the French as well as the American College of Obstetricians and Gynecologists. The optimal strategy for IOL in case of PROM with an unfavourable cervix remains unknown and none of the studies conducted in nulliparous women showed the superiority of one induction method over another. In the current project, we aimed to determine (1) if IOL with association of balloon catheter and oxytocin after 6 hours could increase the rate of delivery < 24h versus low dose of oral misoprostol (25 µg oral PGE1 every 2h) in case of PROM at term in nulliparous women and (2) patient satisfaction using EXIT survey assessed before hospital discharge.
The objective of this work is to evaluate perineal elasticity and deformation and the perineal stresses induced by the fetus during delivery.
The anterior cruciate ligament is one of four key ligaments in the knee. It is the most commonly injured knee ligament with an estimated 200,000 injuries occurring each year in the US (UK data unavailable). Surgery is currently standard treatment for this injury and helps patients return to work and their preinjury activity levels (such as running, playing football or netball). Patients expect surgery to be successful. However, the number of patients who are able to return to their normal activities is low, with only 24% returning at 1 year after surgery. Research has shown that after surgery, patients lack confidence, feel fearful about reinjuring their knee and need to continue to seek advice from healthcare professionals. Receiving physiotherapy before surgery (called 'prehabilitation') is recommended by researchers and physiotherapists to help patients prepare for surgery and postoperative rehabilitation. Although physiotherapy is recommended, some patients don't receive any treatment before their operation, but it is not known why this might be. There are also no guidelines for the treatment patients receive and current treatment varies. If an intervention to be delivered to patients prior to anterior cruciate ligament surgery (prehabilitation treatment package) is developed, patient care may be improved. Patient outcomes could also be improved resulting in more patients returning to physical activity after surgery. This study will firstly, interview participants at three different time points along the patient pathway (1) 12 participants up to 2 weeks before surgery, (2) 12 participants 3 months after surgery, (3) 12 participants 12 months after surgery. The interviews will allow participants to tell the story of their experiences from the point of receiving their injury diagnosis to returning to physical activity and what they expect from their surgery. Secondly, the prehabilitation treatment package will be designed with healthcare professionals, therapy managers and patients.
Breast implants, like all implantable medical devices, are subject to wear and tear as they age in the body. In addition to this wear and tear, they are subject to external trauma, whether accidental during daily life, during insertion or during mammography. The kinetics and mechanisms of aging are poorly studied and the phenomenon of implant rupture is not elucidated. However, studies of older generation implants have shown that implant rupture is correlated with the duration of implantation.
To find the preferred method of labor induction (birth augmentation) for women with a history of one prior cesarean section scar and in grandmultiparas, the difference in time interval from augmentation to delivery will be measured between breast stimulation vs. low-dose oxytocin administration in this prospective single-center randomized controlled trial.
Protein convertase subtilisin/kexin type 9 (PCSK9) plays a regulatory role in cholesterol homeostasis by promoting low-density lipoprotein receptor (LDLr) degradation. Although the vast majority of the studies have focused on the role of PCSK9 in LDLr expression in the liver, an increasing body of evidence suggests that PCSK9 gene is also present in extra-hepatic tissues. A recent publication showed for the first time that PCSK9 is expressed in the ischemic heart and the expression is highest in the zone bordering the infarcted areas. Furthermore, the expression of PCSK9 is maximal early, at 1 week of ischemia. Mechanical complications (or cardiac ruptures) are uncommon but potentially lethal sequelae of acute myocardium infarction (AMI) and are commonly associated with early mortality without appropriate surgical intervention. It's unknown why some patients develop these devasting complications following AMI, while others not. Interestingly, studies have shown that post-infarction cardiac rupture affect the border zone between the ischemic and normal area and occur within the first 3 to 5 days after AMI. Based on the aforementioned observations, it's likely to assume a relationship between PCSK9 expression and the development of post-AMI cardiac rupture. Therefore, the main purpose of the this project is to study the PCSK9 gene polymorphism and its association with cardiac rupture. Investigators hypothesize that PCSK9 expression/secretion and development of post-AMI cardiac rupture may be a part of the dynamic changes at cellular levels occurring in the ischemic heart of genetically predisposed patients.
Anterior cruciate ligament (ACL) injury is a prevailing problem among sports participants, especially in non-contact sports. Studies have reported that 70-84% of ACL injuries are non-contact in nature, and movements like changing in direction while running, cutting and pivoting on a planted foot have resulted in a majority of ACL injuries. Even after ACL reconstruction (ACLR) surgeries, study has reported a 30-50% prevalence of developing patellofemoral joint (PFJ) pain in 1-2 years post-operation. Whole body vibration (WBV) therapy has been gaining attention as an effective method of training in recent years. It has been proved to have a positive effect on improving muscle strength, muscle activities, muscle power and loading during drop jump. Though duration of WBV may differ according to the effect of interest, several studies have had positive results with a 8 week WBV therapy in increasing muscle strength, proprioception, and post-ACLR knee functions. Further investigation on the underlying mechanism and possible application are to be continued to explore more possibilities with the WBV therapy.
Muscle strength and muscle volume decrease rapidly with the immobilization process after sports-related injury and surgery. Depending on the decrease in muscle strength and muscle volume, functional performance also deteriorates, and this has been demonstrated by studies in the literature. Despite rehabilitation programs after anterior cruciate ligament surgery, muscle weakness persists for a long time and this affects knee functions. As a result, the time to return to sports is delayed or the activity level decreases. In recent studies, cross training is used to gain strength. Cross training is the increase in strength in the untrained leg after unilateral strengthening of the untrained leg. Another popular application for strength gain is exercise training with blood flow restriction. Blood flow restriction exercise training is an exercise protocol based on external pressure restriction of blood flow through the cuff from the proximal of the target muscle. It has been shown that this training prevents reduction of muscle volume in the early postoperative period and increases muscle strength. In the literature, cross-training and blood flow-restricted training are applied separately for muscle strength development after ACL reconstruction. However, no study investigating the effect of the combined application of these two approaches on muscle strength during ACL rehabilitation has been found. It is thought that with the combined application of these approaches, their effects on muscle strength development will increase, and accordingly, the functional results of individuals will be positively affected. The aim of the study is to determine the effect of cross training applied with and without blood flow restriction on muscle strength and function for 8 weeks starting from the 4th week after anterior cruciate ligament surgery. Participants will be included in the training for a total of 16 sessions, 2 days a week for 8 weeks. Pain, muscle strength, muscle thickness, knee functions will be evaluated before and after the training.
Background: Despite surgical reconstruction and rehabilitation, individuals after a primary anterior cruciate ligament injury have a significantly increased risk of relapse. The mechanisms for this increased risk may go beyond mere physiological and biomechanical changes of the reconstructed anterior cruciate ligament. The loss of ligamentous mechanoreceptors can affect sensory feedback and consequently result in a disrupted afferent input to the central nervous system. However, research on the neuroplasticity of the central nervous system after anterior cruciate ligament injury and more specifically on the cooperation between different brain areas (=functional connectivity) in motor execution and performance is limited. Research purpose: To investigate the changes in terms of functional connectivity in the brain after sustaining an anterior cruciate ligament injury and associated reconstruction? Population: - Patients after anterior cruciate ligament reconstruction - Healthy controls Protocol: First, all participants are required to complete several questionnaires regarding the level of anxiety and the functioning of the knee in daily activities and sports. In addition, during the baseline testing, participants will be required to perform an experiment while electrical brain activity is recorded by means of an electroencephalography (EEG) measurement. During this experiment, the participants will have to successively perform the following exercises: 10x knee extension from sitting (left and right), 10x bipodal squat from standing, 5x 30 seconds unipodal standing (left and right). The above protocol will be administered to the patient group for the first time 8 weeks after the anterior cruciate ligament reconstruction. When the patients do not need further rehabilitation, they will be invited a second time to execute the same protocol again. The control group will only have to carry out the above protocol once. Finally, for one year after the last test, the patient group will be contacted monthly to monitor return to sport and the occurrence of injuries.
