Filter by:The objectives of this study are to test the preliminary safety and efficacy of a two-day peri-operative course of treprostinil in reducing ischemia-reperfusion injury in adult patients receiving a deceased donor kidney transplantation. Treprostinil, a prostacyclin analog, is expected to facilitate the restoration of blood supply to the revascularized kidney graft via its vasodilatory actions, well characterized protective effects, and longer elimination half-life. These properties and actions of treprostinil make it a strong drug candidate to reduce kidney graft dysfunction during kidney transplantation. An anticipated 20 participants undergoing deceased donor kidney transplant will be hospitalized and intensively monitored during an entire two-day Treatment Phase. An IV infusion using a dedicated central venous line will be used to administer treprostinil commencing approximately 2-3 hours before transplantation of the kidney graft and will continue for approximately 48 hours after completion of the transplant surgery. The primary endpoints include the safety and efficacy of treprostinil, with secondary endpoints including the evaluation of both biochemical and clinical endpoints post-transplantation.
Background: About 700 patients per year undergo an abdominoperineal resection (APR) for distal rectal cancer (Dutch Colorectal Audit 2016).Neoadjuvant (chemo)radiotherapy is often used to further improve locoregional control. Morbidity after APR is substantial and mainly consisting of perineal wound problems in about 35% of the patients. lf primary healing of the perineal wound after APR doesn't occur, secondary healing can take up to one year, and there is even a small proportion of patients in whom a chronic perineal wound or fistula persists after one year. During this long period, intensive wound care is necessary. This results in a heavy burden on both patient and health care resources. Objective: The high morbidity rate of the perineal wound has resulted in a continuing discussion on how to close the perineal defect after APR. Our research group recently published the BIOPEX-study (NL42094.018.12), in which 104 patients were randomized between primary perinea! wound closure and biological mesh closure of the pelvic floor after APR with preoperative radiotherapy for rectal cancer. Similar uncomplicated perineal wound healing rate at 30 days (Southampton wound score < 2) was found: 63% versus 66%, respectively. The hypothesis behind this negative trial result is related to the perineal dead space between the skin and the biological mesh. Fluid will accumulate in this dead space with the risk of secondary contamination and abscess formation, leading to wound dehiscence and purulent discharge. Autologous tissue flaps have been suggested to improve perineal wound healing based on several cohort studies. At least in the Netherlands, these flaps are used only for selected patients with the large defects and highest risk of wound problems, because of the more extensive surgery with added surgical trauma and operative time, and associated donor site morbidity. For these reasons, primary perineal closure (control arm of BIOPEX) is still the standard of care in the Netherlands. A gluteal turnover flap (GT flap) is a small transposition flap trom the unilateral adjacent perineal skin and subcutaneous fat, which is flipped into the perineal dead space, and stitched with the de-epithelialised dermis to the contralateral pelvic floor remnant. Subsequently, the perineal subcutaneous fat and skin are closed over the flap in the midline, thereby not adding a donor site scar. A small pilot study trom our group showed that this is a promising solution for routine perineal closure after APR. Study design: In this multicenter single blinded study, eligible patients will be randomized between pelvic floor reconstruction using a GT flap (intervention arm) and primary closure of the perineal defect (standard arm). The perineal wound healing will be evaluated at 14 days and 1, 3, and 6 months post-operatively using the Southampton wound scoring system by an independent observer.
In France, the average incidence of thoracic trauma is 10,000 to 15,000 each year. These patients are at risk of early and late post traumatic respiratory complications as follows: pneumonia, Acute Respiratory Distress Syndrome (ARDS), hypoxemia. Main issues of thoracic trauma management were recently published by French anesthesiologist and intensivist experts. Non-invasive ventilation (NIV) was recommended in case of severe hypoxemia (PaO2/FiO2 < 200). In comparison to conventional oxygenation or mechanical ventilation, NIV reduced length of stay, incidence of complications and mortality in case of severe hypoxemia. For mild or moderate hypoxemic patients, no devices were tested to prevent respiratory complications. At the moment, low-flow oxygenation is administered to these patients in the absence of severe hypoxemia. Recently, many studies have found promising results with high-flow oxygenation delivered by nasal cannula. This device has many physiological advantages: wash out the naso-pharyngeal dead space, increase end expiratory lung volume, deliver a moderate or low level of Positive end-expiratory pressure (PEEP), improve work of breathing and confort. Several randomized controlled trials tested this device in many clinical settings, but there are no studies on its use after thoracic trauma. A comparative trial is needed to evaluate early prophylactic administration of high-flow oxygenation after thoracic trauma.
The current study aims to evaluate different doses of PC-SOD injections for efficacy and safety in comparison to placebo, in order to provide a basis for future clinical trials in terms of experimental design and dose selection.
The purpose of this study is to determine whether a single treatment with administration of 400 Units NT 201 (botulinum toxin) is superior to placebo (no medicine) for the treatment of lower limb spasticity caused by stroke or traumatic brain injury (Main Period). Participants will be assigned to the treatment groups by chance and neither the participants nor the research staff who interact with them will know the allocation. The following 4 to 5 treatment cycles will investigate the safety and tolerability of treatment with NT 201 (botulinum toxin) when administered in doses between 400 and 800 Units (Open Label Extension Period). All participants will receive the treatment and the dose will depend on whether only lower limb spasticity or combined upper and lower limb spasticity are treated.
Traumatic brain injury (TBI) is the most common type of nerve injury and it severely endangers the public health. It is necessary to accurately measure the early neurological function of brain injury for monitoring its prognosis and therapeutic interventions. Glasgow Coma Score (GCS) and Computed Tomography (CT) are often used to diagnose the severity of TBI. However, GCS has its drawbacks in the observation of prognosis, because it is interfered by analgesics, sedatives and relaxants in the evaluation of neurological function. CT may miss the diagnosis of diffuse axonal injury (DAI) and the monitoring of intracranial pressure (ICP). Secondary injuries after TBI, such as oxidative stress, inflammatory damage, and abnormal metabolism, can destroy cerebral blood vessels and structures, which also affect the diagnosis of injury. Therefore, there is an urgent need for new methods to quickly identify which patients are likely to suffer brain injury or even cause persistent disability. Detection of brain injury biomarkers based on blood and brain tissue has long been used to assess the severity of TBI, but no biomarkers have been found for early diagnosis of mTBI and prognosis of different degrees of brain injury. Protein and metabolic product differences were detected from blood or the lesion samples of normal population, patients with traumatic brain injury and/or non-brain injury using mass spectrometry proteomics and metabolomics analysis platform, and diagnostic markers of potential traumatic brain injury were found, and their differential and diagnostic values were discussed.
The objective of this study is to evaluate clinical and patients-centered parameters of 3-month outcome of the enamel-derived matrix (EMD) application on wound healing process of the donor palatal area after free gingival graft (FGG) removal.
The object of this study is to investigate the damage to the retinal nerve fiber layer (RNFL) and ganglion cell complex layer (GCL+) in diabetic patients without retinal microangioma as detected by fundus fluorescein angiography (FFA) and to determine the kind of nerve damage more likely to indicate early injury.
Anterior cruciate ligament (ACL) injuries are extremely common. On average, 50% of individuals suffering an ACL injury will develop radiographic osteoarthritis (OA) 10 to 20 years after injury. Unfortunately, ACL reconstruction does not prevent risk of future OA. Interleukin-1 (IL-1) levels in the human knee joint increase transiently after an ACL injury. In animal experiments, if interleukin-1 levels are increased in the joint, this alone causes arthritis to occur. Interleukin-1 receptor antagonist (IL-1Ra) is a naturally occurring inhibitor of IL-1. However, in ACL injuries the balance of these two proteins is disturbed transiently after injury, with the effects of IL-1 dominating this balance. In a large animal model of ACL injury, injection of IL-1Ra into the knee joint after ACL injury significantly decreased the amount of arthritis that was later observed. Thus, the investigators hypothesize that early injection of IL-1 inhibitor (IL-1Ra) into the knee joint of patients suffering recent ACL injury will decrease the incidence of cartilage damage later in life. After appropriate IRB approval, a total of 32 active patients will be randomized into one of two treatment groups. Group 1 will receive removal of the knee joint fluid (aspiration of hemarthrosis) using a needle and syringe within 1 to 2 weeks of injury. Following aspiration of the knee joint, an injection of 5 milliliters (mls) of sterile saline (as a placebo control) will be administered. In addition, a second knee aspiration procedure and an injection of 5mls of sterile saline into the injured knee joint will be performed at 3 to 5 days after the initial injection. Group 2 will receive aspiration of the knee hemarthrosis as described in group 1 as well as intra-articular administration of 150mg (~5mls) of anakinra (rhIL-1Ra) within 1 to 2 weeks of ACL injury. In addition, a second knee aspiration and intra-articular administration of 150mg (~5mls) of anakinra (rhIL-1Ra) will be performed at 3 to 5 days after the initial injection. Thus, all patients in this randomized placebo-controlled trial will undergo two injection procedures prior to surgery. Investigators will analyze subjects self-reported function and pain scores as well as urinary levels of cartilage breakdown products over time. Additionally, MRI studies will be used to compare MRI findings among patients in these 2 treatment groups. Urine samples will be obtain prior to surgery, at the time of surgery and at multiple time points after surgery (3, 6, 9, 12 and 24 months after surgery). Subjective outcome measure assessments (surveys) will be completed by participants prior to surgery and then again at 6, 9, 12 and 24 months post-operatively. MRI studies will be obtained at 1 year and 2 years following surgery. Additional, MRI studies at time points are optional and highly encouraged. These additional MRIs are at no cost to the patient.
Alcohol is one of most common harmful substance, and alcohol intake brings great burden on health worldwide. Excess alcohol intake may lead to alcohol-related brain injuries and cognitive impairment. Although both nerve growth factor and antioxidative treatment were effective to relieve alcohol-related injuries in central nervous system in the preclinical studies, there is no relevant clinical trial about their efficacy and safety on patients. Since nerve growth factor and one of the antioxidative medication, edaravone, have been used in some neural diseases in clinical trials, we tend to evaluate the efficacy and safety of nerve growth factor, or edaravone on alcohol-induced brain injuries. The study is a randomized-controlled study and the patients will be assigned into one of the following three groups randomly: (1) regular treatment (combination of vitamin B1, B6, C, E and mecobalamine) with nerve growth factor for 2 weeks and subsequently regular treatment for 6 months; (2) regular treatment (RT) with edaravone for 2 weeks and subsequently RT for 6 months; (3) RT alone for 6 months. The patients will be followed up for 6 months. Cognitive functions, recurrence of alcohol dependence, duration of abstention, alcohol intake, craving for alcohol and other psychological assessments will be recorded and compared among the 3 treatment groups and the efficacy of nerve growth factor or edaravone will be evaluated in our study.
