Active clinical trials for "Wounds and Injuries"

The purpose of this study is to assess for vasospasm using Transcranial Doppler (TCD) and brain injury biomarkers, and evaluate neurocognitive outcome data in pediatric traumatic brain injury (TBI) patients who have experienced a mild to severe head injury.

Surgical trauma triggers a massive inflammatory response. Over time, both the innate and adaptive branches of the immune system are affected by surgical trauma. The purpose of this study to characterize the cellular and molecular mechanisms immune response to surgical trauma. Additionally, detailed information about patients' recovery profile will be recorded over a period of 6 weeks, with the eventual goal of linking immune responses to recovery profiles.

The goal of this phase of the project is to identify the elements of the Theory of Planned Behavior (TPB) that should be targeted to provide the most influence on older adults' behavior (or other stakeholders) to purchase and wear protective headwear. The investigators also intend to determine the format of communication (social marketing/academic detailing) that is most influential for different key stakeholder groups. The TPB has been useful in understanding behavior change related to exercise and adaptive equipment use (such as grab bars, canes, hip protectors); in understanding how a person's attitudes, subjective/social norms and perceived behavioral control inform the development of intention that leads to behavior change.

Objectives To characterize mechanical ventilation practices during general anesthesia for surgery To assess the dependence of intra-operative and post-operative pulmonary complications on intra-operative Mechanical Ventilation (MV) settings

Following spinal cord injury (SCI), the body loses normal control of blood pressure and heart rate, and there is a risk of sudden and dangerous increases in blood pressure, namely, autonomic dysreflexia (AD). It is important to be aware of baseline blood pressures and heart rates in individuals in order to detect AD. However, baseline values vary in developing children, and may be more variable in children with SCI. Thus, the objective of this study is to determine baseline blood pressure and heart rate measurements in children with SCI during rest and during urodynamic testing. The investigators hypothesize that 1) blood pressures will increase with increasing age and body mass index; 2) heart rate will decrease with increasing age; 3) blood pressures will increase with increase in bladder filling; 4) blood pressures will increase will increase with increasing duration of injury.

Procure blood specimens from individuals presenting to the emergency department with suspected brain injury.

This study is to collect blood and urine samples to help identify and validate protein biomarkers of recovery from moderate or severe acute kidney injury (AKI).

Across the world, the most common cause of dying in the ICU is a disease called "sepsis". Sepsis is a disease in which the body's protective response to infection becomes too intense, unnecessarily damaging important organs in the body. Kidney damage during sepsis is particularly bad, as a person's chance of survival drops significantly when he or she develops kidney failure. This study plans to learn more about how to detect (and thus prevent) kidney failure early in sepsis. The current tests doctors use only detect kidney failure once it's already happened. We must therefore find better ways of detecting kidney failure earlier, when there is still a chance to protect the kidneys. In this study, patients will provide a one-time sample of urine. We will check this urine for signs of a protein called "heparanase", which we believe is important in early kidney failure. We will then see if high heparanase activity in urine predicts the risk of developing kidney failure. We will compare results from patients with sepsis with results from patients with trauma, allowing us to determine if heparanase is only important in sepsis kidney failure.

The purpose of this study is to be able to better describe the incidence, timing and severity of myocardial dysfunction and acute kidney injury (AKI) following a documented respiratory viral illness (RSV, adenovirus, metapneumovirus, parainfluenza, influenza, etc.) in pediatric patients.

Neuroglobin has been described as a marker of traumatic brain injury. Nogo-A plays an important role in mediating neuroanatomical plasticity and functional recovery following traumatic brain injury. The investigators sought to examine the changes in serum neuroglobin and Nogo-A concentrations in patients with traumatic brain injury during the initial 96-h posttraumatic period and assessed the relation of neuroglobin and Nogo-A to Glasgow Coma Score and prognosis of such patients with traumatic brain injury.
