Filter by:Treatment of extensive deep burn residual wounds is a common problem in burn plastic surgery. Due to bacterial invasion, excessive maturation of granulation tissue, poor abrasion resistance of new epithelium, and coexistence of wound healing and dissolution can lead to delayed wound healing. Residual wounds rarely heal spontaneously and are prone to recurrence. Mesenchymal stem cells (MSC) boost tissue repair through paracrine. Many biological effectors, including IGF-1, vascular endothelial growth factor (VEGF), TGF-β1 have been found in MSC conditioned media (MSC-CM), and play a role in promoting tissue repair and regeneration.Our previous animal experiments have confirmed the role of MSC-CM in regulating wound inflammation, repairing damaged repair cells and promoting wound regeneration. In here, we will evaluate the safety and effectiveness of mesenchymal stem cell conditioned medium-derived pleiotropic factor in treating residual burn wound.
Retrospective study, which analyzed 100 medical histories of patients who were admitted o the Neurological Rehabilitation Ward of the Rehabilitation Clinic in the Orthopedic-Rehabilitation Hospital in Poznan in years 2010-2019.
The purpose of this small, research study is to examine effectiveness of an at-home application of an experimental intervention, on thinking and memory in mild-moderate, closed-head, traumatic brain injury cases. The experimental intervention is light-emitting diode (LED) therapy, which is applied to the scalp and through the nose using a head frame device. Participants are expected to complete two, 5-week series of LED treatments, at home, 3 times a week. There will be a 1-month period between the two series. Each home treatment is 20 minutes. Participants will be trained to use the head frame device, in-office. The head frame device falls within the FDA category General Wellness, low-risk devices, and no medical claims are made. A two-hour paper and pencil testing (4 visits) and a one-hour MRI (3 visits) will be administered before and after each treatment series. Participants may be in the study for about 4 months. This study is supported by Vielight, Inc., Hayward, CA/ Toronto, Canada
Evaluation Of Cross Mental Nerve Transfer In Restoration Of Chin &Lip Sensation Post Inferior Alveolar Nerve Injury
Many amputees suffer from Phantom Limb Pain (PLP), a condition where painful perceptions arise from the missing limb. Leg amputees wear prostheses that do not provide any sensory feedback, apart from the stump-socket interaction. Increased physical effort associated with prosthesis use as well as discomfort often lead to rejection of artificial limbs. Additionally, the perception of the missing limb and its brain representation, do not match-up with what amputees see (the prosthesis) and this is made worse by the absence of sensory feedback. Therefore, re-establishing the sensory flow of information between the subject's brain and the prosthetic device is extremely important to avoid this mismatch, which creates inadequate embodiment. This study focuses on improving functional abilities and decreasing PLP in amputees thanks to the use of a system able to generate a sensory feedback (SF), which will be provided with a non-invasive electrical stimulation (ES). First, the possibility of enhancing the performance in different functional tasks thanks to the use of SF will be explored. Furthermore, it will be evaluated if SF enhances the prosthesis embodiment and helps restoring a multisensory integration (visuo-tactile), potentially providing also a pain relief. Once tested this system on amputees, also people with peripheral neuropathy and sensory loss will be recruited. Diabetic patients can suffer from symmetrical polyneuropathy (DSPN), which is a common complication caused by prolonged glucose unbalanced levels that lead to nerve damage. Non-invasive ES has been proposed and used as a therapy to treat the chronic pain conditions. In particular, TENS (transcutaneous electrical nerve stimulation) is a type of non-invasive ES, which is able to activate large diameter afferent fibers. The gate control theory of pain states that these large diameter fibers inhibit central nociceptive transmission with a resultant decrease in pain perception. Therefore, also these patients will be recruited to see whether adding a non-invasive SF can enhance their functional motor abilities while diminishing their pain. The subjects will perform a pool of the following tasks, depending on their residual abilities: motor tasks (walking on ground level and on stairs), cognitive tasks (dual tasks), subjective evaluation of prosthesis weight and description of sensations from ES. Some tasks will be performed in Virtual Reality environments with and without an active stimulation.
The aim of this study was to evaluate, in patients with "normal fluid status" assessed by the bio-impedance analysis, whether two different protocol of IV isotonic saline infusion are associated with different volume expansion and differing risks for Contrast Induced Acute Kidney Injury in patients undergoing coronary angiographic procedure.
Acquired Brain Injury (ABI) is a sudden lesion in the brain, not congenital or perinatal,caused by various pathologies.According to the National Statistics Institute,in Spain 78% of people suffering from ABI are a result of stroke,and 22% due to Traumatic Brain Injuries (TBIs) and other causes.The ABI is in most cases with problems of cognitive,physical,emotional,social,family and work.Of all these problems,attentional alterations are one of the most frequent and disabling for these participants,with a prevalence of 30-62%.However,there are currently no specific programs for the rehabilitation of attentional processes in people with ABI in Spain.So recently,a program focused on the rehabilitation of NeuronUp APT attentional processes has been developed,based on the theoretical model of Sohlberg and Mateer,which considers attention as a multidimensional cognitive function that is hierarchically organized.This program includes a large group of rehabilitation activities in contexts similar to those of daily life.Objectives:1)Evaluate the effectiveness of the NeuronUp APT attentional training program for the improvement of the attention problems presented by participants with ABI;2)determine whether the improvement of attention problems in participants with ABI causes changes in their functioning emotional and quality of life and 3)determine whether the improvement of the attention problems in participants with ABI causes changes in the functionality of the participants and, consequently, in the activities of their daily lives.Method:This is a randomized clinical trial, 46 participants with ABI between the ages of 18-65 will be recruited; 23 participants will be assigned to the experimental group (integral rehabilitation+NeuronUp APT) and the other 23 to the control group (integral rehabilitation) randomly,using a simple randomization method.Both groups will be evaluated before the start of the intervention, after the end of the intervention and 6 months after the intervention, thus collecting sociodemographic information,clinical characteristics of the disease, cognitive screening measures,emotional functioning test,functional and quality of life.Conclusions:It is hoped to achieve a transfer of the gains obtained,through the training of the attention through the NeuronUp APT rehabilitation program,to other aspects of cognitive,emotional functioning and quality of life.It is also expected that these people improve their attention problems in their daily lives.
There is evidence that human umbilical cord blood-derived mesenchymal stem cells (hUCB-MSCs) can differentiate into oligodendrocytes and neurons, and improve the recovery of nerve function, which strongly suggests the feasibility and effectiveness of hUCB-MSCs as an intervention treatment for spinal cord injury. At present, there are only a few clinical centers in which hUCB-MSCs transplantation for treatment of chronic spinal cord injury has been performed and a certain degree of efficacy has been achieved. However, this has not been supported by systematic standardized randomized controlled trials. Therefore, the investigators design a prospective, randomized, open-label, parallel, controlled trial to evaluate the efficacy of human umbilical cord-derived mesenchymal stem cells (hUC-MSCs)/hUCB-MSCs to treat spinal cord injury. The primary objective of this study was to investigate whether hUC-MSCs)/hUCB-MSCs transplantation can improve the locomotor function of patients with spinal cord injury. The secondary objectives were to investigate whether hUC-MSCs)/hUCB-MSCs transplantation can improve the muscle tension of patients with spinal cord injury and investigate the complications and safety of hUC-MSCs)/hUCB-MSCs transplantation.

Patients operated on who meet the inclusion criteria between 00:01 on day 0 and 23:59 on day 30 of the selected study period will be included. Validation: We will employ a method of data validation in every centre that will give us a quantitative estimate of case ascertainment that is feasible even in low-resource centres.
In cases of cardiac surgery or sepsis which cause inflammation, oxidative stress, endothelial injury and vasoplegia, serum vitamin C concentration is sharply decreased. The anti-inflammatory and anti-oxidant effects of vitamin C and the effects of reducing vasoconstrictor use have been demonstrated in patients with sepsis and septic shock, however, the foregoing effects have not been validated in patients undergoing cardiac surgery. In this study, investigators investigate the effect of intravenous vitamin C on the incidence of acute renal injury after valvular heart surgery.
