Filter by:Background: Acute myocardial infarction (AMI) has remained a leading cause of mortality and disability worldwide. Although percutaneous coronary angioplasty (PCA) is the best treatment for these patients, paradoxically this procedure causes reperfusion injury. Considerable efforts aimed to reduce this damage have been made, but the results are disappointing and there is still no effective therapy for preventing the damage. Previously, the investigators have achieved a reduction of infarct size in an experimental model of an isolated rat heart, through a synergistic effect of three compounds in a "combined antioxidant therapy" (CAT). In this study, the investigators aim to describe the pharmacokinetics and safety of CAT intravenously administered to healthy subjects. This is the first step to a later clinical application of CAT in AMI patients. Methodology: The safety and pharmacokinetics of the CAT (deferoxamine, N-acetylcysteine, and ascorbate) will be assessed in healthy volunteers in a "phase I clinical trial". Two different formulations (mass of CAT components by bag) with different infusion rates each one will be tested (CAT1 and CAT2). Subjects (18-35 years old, n=18) will be randomized 1:2 to receive a placebo or CAT for 90 minutes. Blood concentrations of each CAT component will be measured in plasma at 0, 15, 30, 60, 90, 120, and 180 minutes after the infusion onset. Adverse events will be registered from the onset of infusion until day 30.
Randomized multisite two arms study in which one arm of patients will be treated with Negative Pressure Wound Therapy (NPWT) known also as Vacuum-assisted closure (VAC) treatment ("VAC Arm") and the second arm of patients will be treated with MedCu wound dressings with copper oxide (COD) ("Copper Arm"). The study goals are to compare the efficacy, cost and convenience between MedCu Wound Dressings with Copper Oxide (COD) and Negative Pressure Wound Therapy of diabetic foot wounds.
Healthcare workers are exposed to many important risks that will negatively affect their health in their working environment. Among these risks, the most important threat is needlestick injuries. Needlestick injuries in healthcare workers with work-related injuries among studies, and the prevalence of injury remains high. In a study conducted by Gheshlagh et al. (2018), the prevalence of needlestick injuries in health workers was found to be 42.5%. It has been shown in studies conducted that the most common decision needlestick injuries among health workers are in nurses. In preventing injuries, preventing, and controlling negative behaviors related to the safe use of needlestick tools is among the most important strategies. In addition, the use of evidence obtained from interventional studies to prevent needlestick injuries in protection programs also plays an important role in prevention. The importance of frequent and regular education about the subject has been mentioned especially in the studies conducted to prevent injuries. The World Health Organization (WHO) has published gold standards in the education of nurses and has recommended the use of electronic learning and simulation methods in the programs of nursing schools for learning and teaching according to these standards. It is important to use evidence-based practices to increase quality and competence by creating realistic clinical environments in nursing education. In this context, it is possible to use simulation-based experiences for educational purposes without exposure to infection control and employee safety in the clinical field. In a study conducted by Nakamura et al. (2019), it was found that a simulation-based training program was effective in infection control. Due to the limited number of studies aimed at protecting the health of healthcare workers and controlling infection, more simulation-based studies are needed in this area. In addition, conducting model-based studies in developing behavior in health workers will also increase success. One of these models, the Precede-Process Model, is an important guide for users in assessing the social, epidemiological, behavioral, and environmental spheres of society for planning and evaluating programs. In summary, the aim of the study is to evaluate the effect of the Precede-Process Model-based simulation training program on preventing needlestick injuries in nurses who are the occupational group most exposed to injury.
Head trauma is a frequent reason for consultation in the emergency room. The CT scan is the reference examination allowing rapid management of the patient. However, CT examinations are among the diagnostic examinations with the highest exposure to ionizing radiation. The study investigators have previously implemented "ultra-low dose" (ULD) acquisitions for several pathologies with an effective dose level similar to that of a standard radiographic examination. These ULD acquisitions are now routinely used in our clinical practice for explorations of the thorax, spine, pelvis and proximal femurs, extremities. This study expands these ULD acquisitions to skull CT for detecting traumatic intracranial lesions. The study investigators hypothesize that it would be possible to search for intracranial lesions in patients with head trauma using ULD protocols, thereby reducing the doses delivered to the patient while maintaining sufficient image quality for the diagnosis.
Injury to the anterior cruciate ligament (ACL) is very common among sports professionals and the general population [. Unlike other joint injuries, it is reversible, but it can damage adjacent tissues, particularly the meniscus, and catalyze knee osteoarthritis. ACL injury produces instability, joint mechanical alteration, which can lead to degenerative joint diseases. The goal of treating the injury will be to prevent symptomatic instability, restore normal knee kinematics, and prevent degenerative joint disease . Its usual treatment is surgical and therefore contributes to a significant cost for the health system, both for the surgeries themselves, and for the rehabilitation and subsequent recovery processes. Within recovery therapies, in some cases, and given their popularity within the world of physiotherapy, electrotherapy techniques are proposed, primarily transcutaneous electrical nerve stimulation-type techniques with action on the muscular system and analgesia. An early intervention with neuromuscular electrostimulation electrotherapy (NMES) combined with repeated exercises is effective for the recovery of strength and restoration of the biomechanical symmetry of the limb. There is a diversity of opinions and disparate results regarding the use of this type of technique , in any case, it has been shown that electrical stimulation favors cell migration and joint tissue regeneration.
The purpose of this project is to compare a newly developed automatic reversing dynamic air mattress, with a regular care mattress, which is in daily use at the hospital. Focus will be on pressure relief in relation to occurrence of pressure injury, user satisfaction, and the mattresses impact on sleep and pain. The participants will be randomized to start with the intervention mattress or the control mattress. Outcomes will be measured via validated forms regarding pressure related injuries, quality of life, pain, and mattress comfort. Custom made forms will be used regarding resource use and comfort in the nursing service, especially in relation to position changes in the participants .
Determining the most appropriate time to evaluate detrusor activity in urodynamic studies for both traumatic and non-traumatic spinal cord injuries
Safety and feasibility study investigating brain biopsy in severe head injury. When a patient undergoes craniotomy or ICP bolt insertion for trauma, a biopsy of brain tissue is taken. Blood, saliva, urine and faeces samples are also taken for 7 days following the brain biopsy. CSF is collected if a CSF drainage device is used.
The aim of this prospective study is to analyze the postoperative paresthesias experienced in patients who undergo bilateral sagittal split osteotomies (BSSO) using an ultrasonic saw, versus a reciprocating saw. Patients included in the study are ages 15-45 scheduled to undergo BSSO surgery at the University of California, San Francisco. One side of the patient's mandible will be instrumented with either the Stryker Sonopet ultrasonic saw or traditional reciprocating saw, while the other side will receive the remaining intervention (determined via randomization on the day of surgery). Patient paresthesias will then be analyzed on each side for 3 months postoperatively (at postoperative days: 1, 7, 14, 28, and 84). Sensory examinations will be carried out by blinded examiners using von Frey hairs and two point discrimination testing. Patients will also subjectively rate their sensation on each side. The results will then be analyzed to determine if patient paresthesias, including the severity and duration, differed depending on which instrument was used, the ultrasonic or reciprocating saw.
