Active clinical trials for "Wounds and Injuries"

Populations at high risk of Sepsis-Associated Acute Kidney Injury (SA-AKI) have been identified. Sources of sepsis, in particular, bloodstream infection, abdominal and genitourinary sepsis, and infective endocarditis, are associated with a higher likelihood of developing AKI. Similar to the poor outcome of patients with sepsis, delayed administration of appropriate antimicrobial therapy was shown to be an independent predictor of the development of AKI. Incremental delays in antimicrobial delivery after the onset of hypotension showed a direct relationship with the development of AKI. The need for sensitive, simple and time-applicable biomarker to predict AKI development after renal insult is urgent. Serum creatinine (sCr) and urea are used routinely for the diagnosis of AKI. However, these parameters are not accurate for the diagnosis of AKI. Cystatin C. (CysC) is suggested to be a good biomarker because of its constant rate of production, almost filtered by glomeruli (99%), has no significant protein binding and not secreted by renal tubule. Neutrophil gelatinase-associated lipocalin (NGAL) is recently identified and extensively investigated as a most promising early marker of AKI. Urinary NGAL is not only effective in detection of AKI but also its degree of expression might distinguish among AKI, prerenal azotemia and chronic kidney disease, and it is detectable before the accumulation of serum creatinine. Ultrasonography (US) is used routinely to assess renal morphology. Renal Resistive Index (RRI) is a non-invasive Doppler-measured parameter that is directly correlated with intra-renal arterial resistance. RRI is defined as [(peak systolic velocity - end diastolic velocity)/ peak systolic velocity]. It theoretically ranges from 0 to 1 and it is normally lower than 0.7 with age differences. RRI calculation was found to be useful as an early indicator of the vascular resistance changes and in the determination of the optimal systemic hemodynamics required for renal perfusion. The aim of this study is to compare the ability of arterial renal resistive index (RRI), serum and urinary neutrophil gelatinase-associated lipocalin (NGAL), Cystatin C (CysC) in early diagnosis and predicting the persistence of acute kidney injury in septic patients.

Single center pilot study examining the effect of Natrox topical oxygen therapy on chronic wounds along with the introduction of remote monitoring and telehealth for home care management.

In civilian practice, the incidence of firearm violence depends on the country. In high income countries, most cases are reported in the USA or South Africa. In these countries, gunshot wounds (GSW) represent 20% of death cases in trauma centers, more than motor vehicle collisions. The mortality in civilian practice occurs during the first 24 hours following GSW, mainly due to hemorrhage and traumatic brain injury, though long term effects on physical and psychological outcomes have also been shown. Some factors of mortality specific to GSW have been established: multiples wounds, homicide vs suicide attempt, impact zone, or firearm caliber. Few specific guidelines have been published concerning civilian GSW management. These cases are mostly treated in standard guidelines, such as hemorrhagic shock or traumatic brain injury guidelines. As in other trauma mechanisms, the "platinum ten minutes and golden hour" concept is applicable. In Europe, the incidence of civilian GSW is much lower and few European studies have been published recently. Penetrating injuries in Europe are less likely to be GSW, and are more often self-inflicted than in the USA. In addition, European studies are heterogeneous, due to the difference in populations, healthcare systems and GSW being grouped with stabbing wounds under the label "penetrating trauma". However, there is a global concern in Europe regarding a potential rise of GSW, with higher severity score than conventional trauma patients and often necessitate ICU admission. Studies analyzing data from different European countries show significantly different ICU admission rates for overall GSW, ranging from 17% up to 30%. Therefore, the investigators conducted a multicenter, retrospective study on four French University Hospitals aiming to describe the epidemiology (mortality and type of organ damage) and identify prognosis factors of civilian GSW admitted in ICU.

After written consent from next-of-kin patients with severe traumatic brain injury was included from the neurointensive care unit (NICU) at Sahlgrenska university hospital, Gothenburg. Blood and CSF samples were collected during the initial 3 weeks after trauma. 1 year after trauma patients were assessed according to Glasgow outcome scale (GOS), NIHSS and Barthels. 10-15 years after trauma a repeated evaluation according to GOS was performed by telephone. Different biomarkers such as Neurofilament light, Glial fibrillary acidic protein and Tau among others, was analyzed from serum and CSF samples. Further patients were explored Apolipoprotein-E genetype (APOE). The investigators hypothesize that higher biomarkers concentrations and positive test for this gene relate to worse outcome 1-year and 10-15 years after trauma. Further that these biomarkers and genetic marker further have prognostic value on outcome 1-year and 10-15 years after trauma. Finally, the investigators want to explore the concentrations dynamics of these biomarkers in serum and CSF in the acute phase after trauma.

Hypothesis: that Oslo Sports Trauma Research Center (OSTRC) Injury Prevention Program has a beneficial effect in terms of injury prevention. The purpose of this study is to investigate the effect of the Oslo Sports Trauma Research Center (OSTRC) Injury Prevention Program in reducing injuries among athletes.

Acute kidney injury (AKI) is a common complication that increases lenght of stay and mortality in trauma patients admitted to the intensive care unit (ICU). The aim of this study is to identify the incidence and outcomes of trauma patients, defined by Kidney Disease Improving Global Outcomes (KDIGO) criteria, at single center level 3 ICU.

Since the 2000s, many prognostic scores were developed to predict traumatic haemorrhage. Most of these studies were retrospectives based on registers. Due to missing data on death due to bleeding, these studies chose to predict the massive transfusion risk as a surrogate of haemorrhagic death. These scores include clinical parameters (vital signs), laboratory values (Haemoglobin, lactate, Base excess) and/or imaging (CT or ultrasound) values. The scores showing best performance are the Trauma Associated Severe Haemorrhage (TASH) score, developed and validated on the German register (DGU-Register) and the ABC score developed and validated in the United States of America. However, the majority of these scores cannot be applied at the trauma scene due to the unavailability of laboratory and imaging values. Therefore, their clinical utility remains unclear. To overcome the need for diagnostic tests, authors have developed and recently validated a clinical prognostic score in identifying trauma patients with, or at risk of, significant haemorrhage based on predicted probabilities of death due to bleeding: BATT score. This score was developed from an international cohort using data from 271 Trauma Centres in 41 countries on 5 continents and uses first clinical parameters at initial assessment. The BATT score predicts death due to bleeding and has been validated on a large population in England and Wales. It could also predict massive transfusion, as a surrogate of haemorrhagic death, earlier at the trauma scene. Its feasibility and external validation would make its clinical utility superior to other scores while identifying a greater number of patients requiring early management. Our study is an external validation of pre-existing prognostic scores of traumatic haemorrhages (TASH , ABC and BATT score) at different times of care (Scene of Injury, admission at the trauma room) in order to assess their overall performance, discrimination and calibration in the prediction of massive transfusion, and haemorrhagic death. The objective of the study is to assess a comparison of score performances (Overall performance, discrimination and calibration). Due to the study population (STR), which is partly integrated into the German DGU-Register, the investigators expect good transportability of the TASH score to the Swiss Trauma Registry in terms of overall performance, discrimination and calibration. The ABC score should show lowers results in terms of discrimination due to its validation on small cohorts exclusively in North America. The new BATT score predicting death due to bleeding has been validated on a large English cohort of more than 100,000 patients. It identifies all patients with haemorrhage and not only patients who have received a massive transfusion subject to survival bias. In this context, the BATT score provides good discrimination with only simple physiological variables available at the trauma scene. In case of its external validation on the STR as part of our study, its feasibility would make its clinical utility superior to other pre-existing scores, while identifying a greater number of patients requiring early management. Its application would activate a massive transfusion plan directly at the trauma scene and save precious time.

The use of quantitative, automated, infrared technology for pupillary examination has long been used in ophthalmology and anesthesiology research. Its interest in neurocritical care has progressively grown, in parallel with the advancements in device technology. In this regard, the use of the noninvasive NPi®-200 pupillometer (Neuroptics, Laguna Hills, California, USA) allows the measurement of a series of dynamic pupillary variables (including the percentage pupillary constriction, latency, constriction velocity, and dilation velocity), which can be integrated into an algorithm, to compute the Neurological Pupil index (NPi). The NPi is a proprietary scalar index with values between 0 and 5 (with a 0.1 decimal precision), an NPi value < 3 indicating an abnormal pupillary reactivity. Importantly, the NPi is not influenced by sedation-analgesia, at the doses used in neurocritical care practice, and by mild hypothermia. Preliminary single-center data recently demonstrated that abnormal NPi is associated with worse outcome in patients with traumatic and hemorrhagic ABI, and can be a useful adjunct for ICP monitoring and therapy. There is currently a great need for quantitative tools to predict early prognostication in ABI patients, and the NPi appears of potential great value. We hypothesize that: Abnormal NPi (defined as NPi <3) are strongly predictive of poor GOS-E (1-4) at 6 months after the acute event. NPi=0 is strongly predictive of mortality (GOS 1). Abnormal NPi is predictive of a higher ICP 20 index (number of end-hourly measures of ICP >20 mm Hg divided by the total number of measurements, multiplied by 100) and a greater burden of interventions needed to control ICP (measured by the Therapy Intensity Level scale for ICP management, Therapy Intensity Level (TIL) 4). Methods This international multicentre prospective observational study aims to recruit >400 patients admitted to intensive care units. Duration of the study 18 months, including 12-month of recruitment based on 60 patients/centre plus 6 months GOS-E follow-up.

Bleeding after Mohs micrographic surgery for skin cancer is a low risk complication that can occur. This study aims to determine the effect of a drug, often used to reduce bleeding, called tranexamic acid when applied topically to the skin wound after surgery.

This study investigates the burden of intermittent catheterization in adult individuals with neurogenic lower urinary tract dysfunction (NLUTD) following spinal cord injury (SCI). Individuals will be recruited to compare two types of catheters. Each participant will use a non-hydrophilic catheter at one time point and a hydrophilic catheter at a different time point to perform intermittent catheterization. The order that participants use either a non-hydrophilic or a hydrophilic catheter will be determined randomly. The purpose of the study is to provide evidence for time spent on bladder management (performing intermittent catheterization) as well as consumer satisfaction on using both catheters.
