The purpose of the proposed study is to test these hypotheses through the following aims: 1. To determine if early plasmin activation following severe injury correlates with SIRS, TIC and complications throughout convalescence in both trauma and surgical patients. 2. To determine if early plasmin activation following severe injury correlates with plasminogen consumption and poor plasmin activity later in convalescence.
UVA-1 has been reported to be beneficial to skin changes in scleroderma in several case reports and a few small studies. (Jacobe 2020) Interpretation of these reports has been difficult based on the small numbers of subjects involved and the non-blinded non-randomized nature of the reports. In a single controlled study with half-side comparison of 9 patients, the investigators could not demonstrate improvement with UVA-1 in the treated hand. (Thomas 2007) This study was limited by a small number of patients and the long disease duration prior to treatment (mean of 13 years). A more recent report of a patient with scleroderma for 2.5 years and severe acrosclerosis that responded to 21 sessions of UVA-1 with improved mobility and functionality renews interest in this treatment modality. (Cuenca-Barrales 2019) In this trial patients will be randomized to have their dominant or non-dominant hand undergo 30 sessions of UVA1 therapy . We will assess patient's hand mobility, hand function, skin hardening (assessed by durometer measurements), skin thickness, as well as patient reported outcomes to determine efficacy. This study will use a single-blind, prospective, randomized (dominant/non-dominant hand) comparator design to assess the effect of high dose (80-120 J/cm2) UVA1 therapy on hand function in scleroderma in a paired t-test design. This study will be placebo-controlled (with a UV-blocking gloved hand), cross-over, randomized clinical trial. Following the initial treatment period (30 treatments), patients will have the option to undergo the same high dose UVA1 treatment protocol on the untreated control hand. A follow up period of 12 months following completion of UVA1 therapy will prospectively follow patients to monitor for relapse of their disease to assess the durability of the clinical response to UVA1 therapy on hand scleroderma.
This is a national multicenter, open-label, randomized controlled trial to show superiority of edge-to-edge Transcatheter Tricuspid Valve repair (TTVr) on top of the Standard Of Care (SOC; heart failure medication) over the SOC alone in patients with symptomatic severe Tricuspid Regurgitation (TR) in the Netherlands.
The purpose of this study is to assess the effect of the Helpers Stay Quit training on abstinence over time of newly abstinent smokers, and on the interactions they have with their personal network related to smoking and smoking cessation.
The goal is to evaluate the acceptance of Augmented Reality (AR) simulation as a learning modality for prehospital providers. The simulation itself is grounded in traditional best practices for simulation delivery and design as well as prior literature on simulation training for prehospital providers; the focus of this study is the participants' experiential interaction with AR and the simulation resources.
Screening for lung cancer has the potential for a profound public health benefit. Repeat annual screening is necessary for early detection of lung cancer. The investigators will test two interventions which include patient education and reminders to improve adherence to lung cancer screening.
This study is an observational study designed to obtain information on the long-term safety, tolerability, and continued activity of Q-Cells®. The study will follow the participants who previously received Q-Cells® for 10 years. The goal of this observational study is to learn about the long term effects of Q-Cells® in people with transverse myelitis. The main objectives the study is to evaluate the safety of patients who have received Q-Cells®. The secondary goal of the study is to get data about the long-term activity of Q-Cells® over a period of 10 years. Patients will complete exams, lab tests, imaging, and questionnaires to monitor their safety.
Low back pain (LBP) is one of the most enormous and challenging disorders. LBP represents a leading cause of disability worldwide. A number of variables (clinical, functional and mechanical) may predispose to back disability. Clinical variables such as pain may affect the patient ability to move and also may result in muscle spasm that led to more pain and movement restriction. Further, functional capabilities may affect the patient and when reduced may lead to disability. Moreover, biomechanical factors such as abnormal posture creates abnormal stress and strain in many spinal structures which are considered predisposing factors for pain and disability. There is a gab of evidence to examine the relationships between those variables and to predict disability in patients with chronic nonspecific low back pain using various variables.
The fertility treatment in vitro fertilisation (IVF), sometimes including intra-cytoplasmic sperm injection (ICSI), involves the creation of embryos in a laboratory. These embryos are then transferred into the womb of the patient with the hope of a resulting pregnancy and live birth. Embryos can also be cryopreserved (frozen) and stored, and then later replaced in a cycle called frozen embryo transfer (FET). There are several methods of preparing the patient's womb to receive the frozen-thawed embryo(s) but commonly embryos are replaced during a medicated cycle. Usually oestrogen and progesterone are administered to prepare the womb lining for embryo transfer at the appropriate time, and in addition a drug called a GnRH antagonist is administered to prevent a women's own hormones from interfering with this process as it is thought this might lead to higher numbers of cycles being cancelled. However, there is some suspicion that this drug (GnRH antagonist) may not be required and that women are using this drug unnecessarily. Some clinics do not use GnRH antagonists in FET cycles, but the investigators do not know if they have higher rates of cancelled cycles as a result. This pilot study aims to compare cycles of medicated FET using oestrogen and progesterone, either with or without pituitary suppression in the form of GnRH antagonist (Cetrotide), in patients over the next 18 months who are planning FET cycles at Oxford Fertility, UK to find out if both give the same chance of having a baby, which treatment is better for patients and to assess the feasibility of undertaking a future larger study. Cetrotide is a marketed and well-known medication and any risk or serious adverse effects are unlikely. The study is an open label prospective randomised controlled trial. Funding for the medication (Cetrotide) is provided by Oxford Fertility.
The purpose of this study is to test the safety and effectiveness of an autologous bone marrow-derived stem/progenitor cells administered intravitreously in the subjects with degenerative diseases of the retina.
