Risk Factors for Acute Kidney Injury in Critically Ill Patients With Acute-on-Chronic Liver Failure...
Acute Kidney InjuryAcute-On-Chronic Liver FailureAcute kidney injury (AKI) is one of the most important factors associated with increased mortality in patients with acute-on-chronic liver failure (AoCLF). Early identification and treatment of this subgroup of patients may improve survival and decrease ICU length of stay. As kidney ischemia is one of the main mechanisms responsible for AKI in AoCLF, an increase in urinary to arterial partial pressure of oxygen may help in the early diagnosis of renal failure. For this arterial and urinary oxygen pressure will be measured at ICU admission, on day 1 and day 3 of ICU stay. Diagnosis of AKI within the first 28 days after ICU admission will be recorded

Study on the Establishment of a System for Early Warning and Prognostic Evaluation of Patients With...
SepsisPrognosis3 moreSepsis is a clinical syndrome with high morbidity and high fatality rate in emergency department. Patients with acute liver or kidney injury are more likely to develop Multiple Organ Dysfunction Syndrome(MODS) secondary to the non-hepatic injury group, and the prognosis deteriorates significantly. At present, there is no unified diagnostic criteria for acute liver injury associated with sepsis, and the commonly used prognostic evaluation system is rarely included in liver injury indicators, which is not good for practicality.

MR Imaging of Perinatal Brain Injury
Perinatal White Matter Brain InjuryThe purpose of this study is to collect and compare information from cranial ultrasounds, magnetic resonance imaging scans, neurological exam and neuropsychological assessments of children. The investigators hope that the information collected in this study will help with early screening, diagnosis and treatment of brain injury in newborns as well as identify a connection between MR imaging (MRI-magnetic resonance imaging, MRS-magnetic resonance spectroscopy) and neurodevelopmental outcome.

Spinal Cord Injury Registry - North American Clinical Trials Network
Spinal Cord InjuryThe NACTN Spinal Cord Injury Registry is a network of clinical centers collecting de-identified data from patients admitted through the Emergency Department of a NACTN center at the time of injury with an initial (first time) spinal cord injury (SCI). Information will be collected on the natural history of SCI and course of treatment through the first 12 months from the date of injury or long as medically indicated. Data collected includes imaging information from CT or MRI scans, neurological and general medical outcome and rehabilitation evaluation. No intervention is given other than standard of care for spinal cord injury, intensive monitoring and frequent follow up care.

Hernia After Colorectal Cancer Surgery
Incisional HerniaWound Dehiscence2 moreDefects in the abdominal wall (incisional hernia) is a frequent negative outcome after surgery. Reinforcing the incision with mesh seem to lower the incidence but in surgery that includes bowel resection a simple alternative, cheaper and less prone to infection than a synthetic mesh, would be of interest. The primary aim of this multicentre randomized controlled trial is to compare the incisional hernia incidence one year after planned colorectal cancer surgery performed through a midline incision which is closed either by a standardized small stitch 4:1 technique (the incision is closed with the use of suture of 4 times the length of the incision) or with the same technique plus a reinforced tension-line suture (a suture is applied in the fibrous tissue parallel to the incision which is then embraced by the 4:1 suture when the incision is closed). A difference in incisional hernia of 15% (20% without and 5% with reinforced tension-line suture) is assumed. Secondary aims are to evaluate incidences of wound dehiscence, other wound complications and incisional hernia after 3 years. Furthermore we aim to evaluate patient satisfaction and quality of life.

China Collaborative Study on Epidemiology of Acute Kidney Injury
Acute Kidney InjuryAcute kidney injury (AKI) is a common clinical syndrome, especially patients in the hospital. AKI has become a huge medical burden in China. Little information is available about this disease burden in our country. The investigators aimed to evaluate the burden of AKI and to analyze the related risk factors.

Hyperpolarized 129Xe Magnetic Resonance Imaging for Evaluation of Radiation-Induced Lung Injury...
Radiation Induced Lung Injury (RILI)The purpose of this work is to perform hyperpolarized (HP) 129Xe MRI in human subjects undergoing thoracic radiation therapy (RT), both before, during and following RT. HP 129Xe MR images will be analysed to provide maps of ventilation (V), perfusion (Q), apparent diffusion coefficient (ADC) and gas exchange. These results will be combined to yield a new measure of RILI, (i.e. dose volume histograms; DVHV/Q) and compared with conventional dose volume histograms (DVH), pulmonary function tests (PFTs), quality of life (QOL) questionnaire and CT measurements for assessment of RILI at each time point. The aim is to development a novel method for early and more sensitive method of detecting RILI before irreversible lung damage happens.

Effectiveness of Contrast-Enhanced Ultrasound
Abdominal InjuriesPhysical Abuse2 moreThe purpose of the study is to generate pilot data describing test characteristics of contrast enhanced ultrasound in young children with concern for abdominal trauma. The primary objective in this study is to determine the sensitivity and specificity of contrast-enhanced ultrasound (CEUS) compared to abdominal Computed Tomography (CT) in the detection of abdominal solid organ injury in young children < 8 years of age with concern for blunt abdominal trauma.

Shoulder Instability in Children: Muscle Activity and Movement
Shoulder InjuriesMusculoskeletal Injury5 moreThe aim of this study is to identify factors responsible for recurrent shoulder instability in children. Shoulder instability, i.e. complete or partial dislocation of the shoulder joint, is common in children, resulting in pain and disability. Recurrent instability can damage the shoulder joint resulting in the premature development of arthritis. Rehabilitation approaches are preferred over surgical methods for the growing child e.g. physiotherapy to restore movement and prevent further instability. Existing rehabilitation procedures are based on addressing factors assumed to be responsible for instability e.g. physiotherapists may try to increase shoulder stability by building up the shoulder muscles to compensate for the damaged ligaments. It is evident however that the mechanisms of shoulder instability are not well understood, as failure rates for physiotherapy are high, with 70% - 90% of children continuing to suffer recurrent instability. This is an observational, cross-sectional study of children (aged 8 to 18) presenting with shoulder instability of any origin, traumatic or atraumatic (n=15) and an age-matched sample (n=15) with no history of shoulder problems. Muscle activity and movement pattern differences will be measured using non-invasive 3D motion capture and surface electromyography, to identify factors responsible for instability. Only a single visit to the site will be required (The Orthotic Research & Locomotor Assessment Unit (ORLAU) based at The Robert Jones & Agnes Hunt Orthopaedic Hospital NHS Foundation Trust in Oswestry.). If investigators better understand the mechanisms associated with instability, physiotherapy interventions to reduce dislocations and disability can be better targeted. If specific patterns of activity associated with instability are identified, these could be addressed through personalised and improved exercise prescription and rehabilitation. Additionally, causes of instability for which physiotherapy may not be appropriate may be identified, therefore ensuring patients are referred to the correct service in a timely manner, improving patient outcomes and allocating physiotherapy resources more appropriately. Participants will be recruited from musculoskeletal/orthopaedic outpatient clinics. This study is funded by the Private Physiotherapy Education Foundation.

Outcome of the Treatment of Flexor Tendon Injuries
Finger InjuriesTendon Injury - HandIn order to gather enough data for meaningful statistics, a multicenter register of all flexor tendon repairs was established with surgical, clinical and rehabilitation patient data. The controlled active motion (CAM) protocol was administered in all patients after surgery. The purpose was to (i) measure surgery and therapy outcomes in the three centers and (ii) evaluate potential influencing factors on outcomes.
