The objective of this study is to test the feasibility and physiological effect of low-frequency (1 Hz) acoustic stimulation delivered during nocturnal NREM sleep in epilepsy patients. The long-term goal is to develop this protocol for daily, long-term use in a home setting, for nocturnal seizure and IED suppression
Uterine fibroids (leiomyomas, myomas, fibroids) are benign tumors of the uterus that can cause heavy menstrual bleeding, pain, and/or infertility. Fibroids can be managed with medication, surgery, or interventional radiology. While conservative methods that avoid surgical risks and complications are becoming more common, there are limitations to medical therapies including side effects, short durations of use, and incomplete response to treatment. To optimize patient outcomes, it is imperative clinicians and researchers better understand which patients may benefit from medical therapies and which may not. Fibroids with less blood supply can degenerate and take on a variety of histological characteristics (e.g. cystic, red, fatty, calcific) which may decrease response to medical management. These histological characteristics in degenerated fibroids correspond to altered mechanical properties, ranging from very soft to very hard. There is currently no guidance on how to predict medical responsiveness based on such fibroid characteristics. As a result, physicians treat patients empirically with medications, without the ability to counsel on effectiveness or failure rates. Our research goal is to understand if and how uterine fibroid tissue stiffness can predict response to medical therapies. To achieve this, the investigators will use a new ultrasound technology, called shear wave elastography (SWE), that non-invasively measures tissue stiffness and is currently used in practice for staging of chronic liver diseases; however, given that this technology is very new, evidence of its clinical application in gynecology is limited. Through implementing an innovative and multidisciplinary approach, the investigators will (1) systematically establish SWE as a feasible and reliable tool for measuring non-neoplastic myometrial and uterine fibroid tissue stiffness, and (2) use SWE to classify and monitor fibroid tissue properties in pre-menopausal women undergoing medical intervention for symptomatic uterine fibroids. Understanding the connection between pathological tissue properties and the success of medical therapies is essential to streamline assessment and intervention planning and improve overall patient outcomes for the many Canadian women who suffer from uterine fibroids.
Patients with COPD that a pulmonologist classifies between Stage 1-2 in accordance with the GOLD criteria and age and gender-matched healthy individuals will be included in the study. In both groups (n = COPD: 17, Healthy: 17), aerobic exercise (AE) in the target heart rate range of 50% intensity, performed by cycling accompanied by blood flow restriction, will be applied.
The purpose of this study is to compare the diagnostic value of a reconstructed abbreviated Magnetic Resonance Imaging (MRI) from a full clinical exam, compared to ultrasound (US) for screening of liver cancer. Blood markers will be evaluated to determine their correlation to imaging. This study will help to determine whether abbreviated MRI is superior to ultrasound for diagnosis of liver cancer.
Our primary objective is to understand the impact of our quality improvement objectives on pressure injury and wound care outcomes. We will follow patients admitted to our facility who receive the standard of care for a up to a year. Patients to be followed will fall into one of four groups: acute wounds, chronic wounds, pressure injuries present at time of admission and at risk for pressure injuries.
This study aims to measure the spinal cord gray matter in patients with spinal muscular atrophy (SMA) type II and III in comparison with age- and sex-matched healthy controls (HC) using rAMIRA (radially sampled averaged magnetization inversion recovery acquisitions) imaging, a novel MRI (Magnetic Resonance Imaging) method. Patient and HC undergo MRI examinations, clinical/neurological (handheld dynamometry) and electrophysiological investigations (MUNIX, Motor Unit Number Index). Serum markers of neuro-axonal and astrocytic injury are also assessed.
Frailty is a term specific to the geriatric period. It is used to describe weak, unstable, frail patients and partially expresses the frailty of the elderly patient. Once the frailty process begins, the risk of loss of mobility, dependency and mortality increases. Frailty is an important predictor of adverse outcomes after surgery. According to studies conducted in various surgical situations, fragility is a major risk factor for morbidity, mortality and longer hospital stay. According to the available data, frailty has a sufficient basis for determining the risks of patients before surgery, developing preventive methods and making personal treatment decisions. As the frailty index increased, it was observed that the duration of postoperative hospital stay was associated with the need for intensive care, postoperative complications, and the rate of re-admissions within 30 days. ASA (American Society of Anesthesiologists) classification is widely used in order to evaluate the physical condition preoperatively in geriatric individuals with multiple comorbidities. Considering the fragility variable while creating the ASA score in the preoperative period may be useful in determining the follow-up strategy during the operation and postoperative period. For example, a patient who is evaluated as ASA 2 because he has no problems other than simple 1-2 comorbid conditions, involuntary weakening of 5% in the last 1 year (not easily noticed), weakness (can only be detected with a dynamometer) and cessation of going out of the house (can only be understood when asked privately). ) can be categorized as at risk at ASA level 3-4, as it is understood to be fragile. The aim of this project is to examine the frequency of frailty in elderly individuals who will be operated on, and to examine the relationship between frailty and ASA score using the anthropometry and comorbidity differences between frail preoperative patients and those who do not.
The purpose of this study is to obtain feedback from patients and orthopedic surgeons who agree to use virtual reality (VR ) as an adjunct to standard of care in orthopedic cases under regional or central neuraxial nerve block. This will serve as a preliminary study for future trials to compare outcomes between VR and standard of care vs standard of care only.
This observational study will enroll adults with open angle glaucoma (OAG) who had surgery to reduce intraocular pressure (IOP) using the CycloPen Micro-Interventional System. Consenting participants will be followed for 24 months after their surgery. Data regarding IOP, use of glaucoma medications, and any side effects related to the surgery will be collected from participants' preoperative examination, their surgery, and postoperative examinations.
Considering the fact that The problems experienced by the patients are not only physiological but also psychological and social. Unfortunately, there is no sufficient study focus on all these concepts. Generally, studies focus on only physiological dimensions such as functional level, muscle strength and pain. The aim of this study, in addition to assessment methods commonly used for functional level, muscle strength and pain, is to evaluate central neuromuscular function on individuals who have undergone rotator cuff tear surgery with transcranial magnetic stimulation. Furthermore, psychological resilience, which is considered as a positive psychological trait, will also be evaluated. Until now, only one study has evaluated the role of psychological resilience in the postoperative process of rotator cuff surgery. This study has shown that the correlation between functionality and psychological resilience. As a result of our study, the influence of resiliency on postoperative outcomes following rotator cuff surgery will be determined and central neuromuscular function, shoulder functional level, and psychological resilience changes will be revealed in physiological and psychological concepts. Furthermore, this study may show that psychological resilience has a potential role on predicting functional level and pain. It is planned that the results obtained will guide the postoperative rehabilitation of rotator cuff surgery for further studies on multidimensional perspectives.
