199 Clinical Trials for Various Conditions
Traumatic injury followed by critical illness provokes pathophysiologic changes in the bone marrow and the gut that contribute to persistent anemia and changes in the microbiome which significantly impact long-term recovery. This project will define the interactions between the stress, chronic inflammation, bone marrow dysfunction, and an altered microbiome which will provide a strong foundation for future clinical interventions to help improve outcomes following severe trauma.
The purpose of this study is to evaluate the efficacy, safety, and pharmacokinetics (PK) of FDY-5301 compared to placebo in major trauma ICU patients at risk of intensive care unit acquired weakness (ICUAW)
This study evaluates if the early utilization of ketamine infusion therapy among acutely injured adult trauma hospital inpatients with an ISS \>15 will decrease the amount of opioid pain medication used as compared with placebo group. Ketamine infusion therapy initiated within 12 hours of hospital arrival will lead to decreased total opiate consumption (standardized to oral morphine equivalent units) in the first 24 and 48 hours compared to controls.
Traumatic injury is a leading cause of morbidity and mortality in young adults, and remains a substantial economic and health care burden. Despite decades of promising preclinical and clinical investigations in trauma, investigators understanding of these entities is still incomplete, and few therapies have shown success. During severe trauma, bone marrow granulocyte stores are rapidly released into the peripheral circulation. This release subsequently induces the expansion and repopulation of empty or evacuated space by hematopoietic stem cells (HSCs). Although the patient experiences an early loss of bone marrow myeloid-derived cells, stem cell expansion is largely skewed towards the repopulation of the myeloid lineage/compartment. The hypothesis is that this 'emergency myelopoiesis' is critical for the survival of the severely traumatized and further, failure of the emergency myelopoietic response is associated with global immunosuppression and susceptibility to secondary infection. Also, identifying the release of myeloid derived suppressor cells (MDSCs) in the circulation of human severe trauma subjects. This process is driven by HSCs in the bone marrow of trauma subjects. Additionally, MDSCs may have a profound effect on the nutritional status of the host. The appearance of these MDSCs after trauma is associated with a loss of muscle tissue in these subjects. This muscle loss and possible increased catabolism have huge effects on long term outcomes for these subjects. It is the investigator's goal to understand the differences that occur in these in HSCs and muscle cells as opposed to non-injured and non-infected controls. This work will lead to a better understanding of the myelopoietic and catabolic response following trauma.
The purpose of this study is to determine the effect of antioxidant vitamins (vitamins C and E) on the development of coagulation derangements and nosocomial pneumonia after severe trauma in patients.
The purpose of this study is to learn more about how to treat patients with severe injuries related to trauma and to prevent failure of vital organs in this patient population. Approximately 200 severely injured patients with blunt trauma and 40 healthy volunteer subjects will be enrolled in this study. During the study seven blood samples (4-5 mls) will be collected from patients who have suffered severe trauma over a 28 day period. A one time 5 ml blood sample will be collected from the healthy volunteers. Clinical data will be collected daily while patients are hospitalized. The initial blood sample must be collected from qualifying patients within the first 12 hours of admission to the hospital. The reason for blood sampling is to validate a rapid genomic test in real time. Once confirmed, this genomic test can be used to identify patients who will have a complicated clinical course and would, therefore, be good candidates for interventional, immunomodulatory therapies.
The proposal will assess if patients who require massive transfusion can be accurately predicted early after emergency department arrival and assess if the use of stored whole blood during initial resuscitation will reduce transfusion needs compared to transfusion with component therapy and thus improve outcome.
The purpose of this study is to investigate the use of ultrasound by aeromedical prehospital providers.
Organ failure following trauma is a leading cause of morbidity and mortality. It appears that the development of organ failure is a direct result of an altered immune response. This altered response results in the production of circulating factors in the blood that causes direct injury to the injured patients' organs. The mechanism in which this altered immune response occurs is unknown. Based on work we have performed in our laboratory, we believe that this response is initiated on the cell membrane of particular immune cells known as macrophages. Although the cell membrane may appear uniform, it is not. The membrane is composed of specific segments that allow proteins to associate with each other forming receptors that are required for immune cell activation. These specific membrane components are composed of various lipids and cholesterol, and have been termed lipid rafts. Based on our laboratory work it appears that these lipid rafts can be altered following injury. In particular both the lipid and protein content within these raft segments may be altered allowing immune cells to become active leading to the production of factors that directly injure normal cells and organs. Thus, we plan to examine if these laboratory findings can be seen in patients suffering from trauma who develop clinical organ failure at Harborview Medical Center. If this is accomplished, this data will lead to the development of both prognostic and therapeutic interventions for the optimal care of injured patient
The objectives of this study are to test and validate a simple, feasible intervention to reduce pediatric burn traumatic stress in 0-5 year old children and their parents. We have refined and implemented an early post-burn psychosocial assessment and intervention for stress reduction for young children and their parents based on the "DEF" Protocol (Distress, Emotional Support, Family) from NCTSN's 'Pediatric Medical Toolkit for Health Care Providers,' and a burn specific version of the COPE (Creating Opportunities for Parent Empowerment)intervention. It is hypothesized that the combined DEF + COPE Intervention will be simple to implement and use under both experimental and real world conditions. The proof of the latter hypothesis will be that staff at Shriners Hospitals for Children-Boston will willingly incorporate it into routine care by the end of the project. We will evaluate, using an RCT design, the DEF + COPE Intervention by comparing outcomes for subjects who are randomly assigned to receive it with outcomes for subjects who are assigned to receive the DEF Intervention only. It is hypothesized that children in the DEF + COPE Intervention Group will show significantly greater decreases over time in pain and anxiety ratings, heart rate, PTSD total symptom scores and physiological symptom scores (such as heart rate and heart rate variability from baseline to follow up) than will children in the DEF-only group. Similarly, it is hypothesized that parents assigned to the DEF + COPE group will show significantly decreased scores on the Stanford PTSD measure.
The purpose of this study is to prospectively evaluate whether the addition of continuous glucose monitoring to point-of-care (POC) glucometer monitoring improves glucose control.
Multi-center, comparative, non-significant risk adaptive study with retrospective controls. After providing informed consent and being screened for eligibility, intervention subjects will be prescribed and provided an appropriately sized Tango Belt. The subject must demonstrate a minimum of 64% adherence to the use of the Tango Belt within 14 days of initiation to fully enroll in the study. Upon demonstration of at least minimum adherence, the subject will be provided the Tango Belt to wear continuously for at least 6 months, except during bathing, device charging, and as deemed by clinical staff. The study will investigate the safety and effectiveness of the Tango Belt with the primary and secondary endpoints being taken every 3 months and at the end of the study run time from the electronic medical record. Additionally, ancillary endpoints on adverse events and device performance will be gathered.
This is a single site double blind randomized controlled trial of replacing Vitamin D for Vitamin D-deficient burn patients at a current recommended dose (400 IU daily) versus a higher dose (4000 IU daily). Capsules will be made in a compounding pharmacy and will look identical. Randomized controlled trial. People who meet the selection criteria will be randomized to either low or high dosage of Vitamin D. Treatment arm is high dose Vitamin D (4000 IU), and control is low dose Vitamin D (400 IU). Main outcome variables include PROMIS-29 measures of physical health, mental health and social health, the Veterans RAND 12 Item Health Survey (VR-12), and the 4-D Itch Scale. Secondary outcome variables include subject demographics, injury demographics and characteristics.
Nonoperative management (NOM) of blunt splenic injuries has been the standard of care for decades. While many splenic injuries can be successfully observed, studies have demonstrated increased failure rates for higher grade injuries, which prompted some institutions to perform SAE prophylactically. The current literature comparing observation and SAE is limited to observational data and is frequently inconsistent. As such, the standard of care varies across institutions and both strategies are considered acceptable management for splenic injuries. Our own institution does not routinely perform SAE and our splenic salvage rate exceed 90% but the investigators noted an increased rate of NOM failure in patients with a contrast blush on CT. Contrast blush is a known risk factor for NOM failure and has been cited as a reason to perform SAE, but even within this population no randomized trials have been performed to demonstrate if SAE improves outcomes. The purpose of this project is to provide definitive high-quality evidence for the effectiveness of SAE to decrease the rate of NOM failure in high grade splenic injuries.
This study will enroll participants with a non-infected, corneal persistent epithelial defect (PED) resulting from an ocular chemical and/or thermal ocular injury which is non-responsive or refractory to current standard of care for at least 14 days. It will assess the efficacy and safety of Nexagon® (lufepirsen) plus standard of care versus NEXAGON-vehicle (placebo) plus standard of care. The recovery of the corneal epithelium will be the primary outcome measure, defined as a cornea that re-epithelializes by Day 28 of treatment and remains re-epithelialized for at least a further 28 days.
With IRB approval and informed consent, patients (n=10) (18-50 years old) with post-traumatic knee OA and requiring a tibial plateau and meniscus arthroplasty plus a femoral condyle arthroplasty will be enrolled in the study. Primary criteria for inclusion will be Grade IV changes in the articular cartilage of the femoral condyle and tibial plateau and meniscal pathology in the medial or lateral femorotibial joint as determined by physical examination, diagnostic imaging and knee arthroscopy by the PI. Exclusion criteria include Grade III or IV changes in any other compartment of the knee, acute injury to any other part of the affected lower extremity, or inability to comply with the protocol. After enrollment, patients will undergo standardized knee radiography, and complete assessments (described below). Size-matched (standard clinical methodology) proximal tibia with meniscus and distal femur allografts from the same donor will be obtained from a tissue bank (Musculoskeletal Transplant Foundation, Edison, NJ) who has licensed the MOPS technology. The medial or lateral femoral condyle will be replaced using our novel instrumentation and technique described above. Tibial plateau-meniscus grafts will be trimmed and used to replace the entire medial or lateral tibial condyle while sparing the attachments of ACL, PCL and respective collateral ligament. The tibial plateau graft will be fixated using commercial available implants used for bone fixation. In the event that the meniscus has been detached from the tibial plateau during graft harvest, the periphery of the meniscus will be sutured to the capsule following standard meniscus transplant procedure. Patients will undergo controlled post-operative rehabilitation according to standard protocols for osteochondral with concurrent meniscus allografts. Range of motion, VAS pain score, SF-12, Tegner score, International Knee Documentation Committee (IKDC) subjective and objective scores, PROMIS Bank v1.2 - Physical Function-Mobility, PROMIS v1.1 - Global Health, PROMIS Bank v1.1- Pain Interference, PROMIS Bank v1.2 - Physical Function and Marx score as well as complete radiographs of the affected knee will be obtained prior to surgery and at 6 weeks, 3 months, 6 months, and 12 months after surgery to evaluate healing, function and evidence for arthrosis.
Patients with severe brain injuries often have slow accumulating recoveries of function. In ongoing studies, we have discovered that elements of electrical activity during sleep may correlate with the level of behavioral recovery observed in patients. It is unknown whether such changes are causally linked to behavioral recovery. Sleep processes are, however, associated with several critical processes supporting the cellular integrity of neurons and neuronal mechanisms associated with learning and synaptic modifications. These known associations suggest the possibility that targeting the normalization of brain electrical activity during sleep may aid the recovery process. A well-studied mechanism organizing the pattern of electrical activity that characterizes sleep is the body's release of the substance melatonin. Melatonin is produced in the brain and released at a precise time during the day (normally around 8-10PM) to signal the brain to initiate aspects of the sleep process each day. Ongoing research by other scientists has demonstrated that providing a small dose of melatonin can improve the regular pattern of sleep and help aid sleep induction. Melatonin use has been shown to be effective in the treatment of time change effects on sleep ("jet lag") and mood disturbances associated with changes in daily light cues such as seasonal affective disorder. We propose to study the effects of melatonin administration in patients with severe structural brain injuries and disorders of consciousness. We will measure the patient's own timing of release of melatonin and provide a dose of melatonin at night to test the effects on the electrical activity of sleep over a three month period. In addition to brain electrical activity we will record sleep behavioral data and physical activity using activity monitors worn by the patients. Patient subjects in this study will be studied twice during the three month period in three day inpatient visits where they will undergo video monitoring and sampling of brain electrical activity using pasted electrodes ("EEG"), hourly saliva sampling for one day, and participation in behavioral testing.
This is a multi-center prospective observational study that will capture detailed information about the treatment and long term outcomes of 250 patients with PNI resulting from upper extremity trauma. The study will focus on a young adult population to include individuals ages 18-65. Patients with PNI will be recruited during the hospitalization for initial treatment of the upper extremity injury. Additional patients may be identified during clinic visits for on-going treatment of upper extremity injuries as nerve injuries evolve or upon referral from outside physicians. However, all eligible nerve injuries must be treated within 6 months of the initial upper extremity trauma. Outcomes will be assessed at 3, 6, 12, 18 and 24 months following diagnosis of the nerve injury. All assessments will take place in the clinic and will include a patient interview and a brief exam to evaluate sensory and motor function.
The purpose of this study is to collect physiologic data from patients with severe brain injury who require mechanical ventilation in order to describe the impact of ventilation, specifically positive end expiratory pressure (PEEP), on intracranial pressure (ICP).
Animal and human data have supported the notion that administration of large doses of Vitamin C has beneficial effects on those subjects suffering from large burns. This effect may be due, in part, to the antioxidant and free-radical-scavenging properties of Vitamin C. These studies have demonstrated an improvement in urine output during resuscitation and reduced need for fluid volumes during resuscitation. In turn, these subjects demonstrated a reduction of wound edema, improved respiratory status (demonstrated by improvements in P:F ratios and reduced ventilator days), and no differences in terms of the possible complications of high-dose vitamin C administration between standard and treatment groups. The purpose of this study is to prospectively determine if Vitamin C can be safely used as an adjunctive treatment for patients suffering severe thermal injuries. High-dose vitamin C administered at a dose of 66mg/kg/hr during the acute phase of severe burn injuries will reduce fluid requirements in the first 48 hours after injury.
The purpose of this study is to characterize the bacteria in the wound "bioburden" at the time of definitive wound coverage/closure of severe tibia fractures in both the military and civilian populations.
The purpose of this study is to determine whether a newly developed, brief cognitive behavioral intervention, relative to supportive counseling, is effective in reducing acute stress disorder (ASD) and preventing post traumatic stress disorder (PTSD) and depression.
This is a randomized, controlled clinical trial at three sites to determine the safety and preliminary efficacy of the study drug to treat severe head trauma (GCS 4-8). It is hypothesized that the drug may lower pressure in the brain, reduce mortality and the patient may have improved neurological function following treatment.
The purpose of this study is to evaluate the efficacy of early conversion tracheostomy from endotracheal intubation (ET) to percutaneous, dilatational tracheostomy (PDT) in traumatic brain-injured patients requiring prolonged mechanical ventilation.
The purpose of this study is two-fold. The first is to establish that bone mineral density is diminished among children admitted to this regional burn center as compared to healthy non-burned children. The second purpose of this study is to examine the short and long-term effects of calcium and vitamin D supplementation in on bone metabolism and accrual in children who have been burned. Specific Aims: 1) To measure bone mineral content and bone mineral density and their change during growth in convalescent burned children admitted to a regional burn center and to compare them to normal, healthy children.; 2) To measure lean body mass, fat mass, total body water in convalescent burned children admitted to a regional burn center and compare them to normal, healthy children with focus on how these components of body composition relate to indices of bone mineral content and density; 3) To identify alterations in bone metabolism and calcium and vitamin D homeostasis following burn injury and relate these to bone mineral density in burned children; 4) To test the effect of short term calcium and vitamin D supplementation on improving bone mineral density, bone mineral content, and indices of calcium and vitamin D metabolism in acutely burned children.
Glutamine is considered a conditionally essential amino acid during critical illness. After severe trauma, glutamine supplementation into the gastrointestinal tract may help maintain bowel function. We hypothesize that for the major torso trauma patient, high dose glutamine given enterally during resuscitation from shock and continued during enteral nutrition support is absorbed, available systemically and preserves gut integrity.
The purpose of this study is to evaluate the clinical outcome of patients following blunt traumatic injury with hypovolemic shock, who receive either lactated ringer's solution or hypertonic saline with dextran (HSD) resuscitation; also, to focus specifically on neurologic outcome in patients with brain injury and on the effect of HSD resuscitation on inflammatory cell responsiveness.
The purpose of this trial is to determine if hypothermia (body cooling), administered very soon after a severe brain injury improves functional outcome. This pilot trial ended in July 2005. Please see clinicaltrials.gov record number NCT00178711 for the Phase III version of the trial (see link below).
The study uses a multi-site, cluster design to determine the effectiveness of an intervention based on a Trauma Collaborative Care (TCC) model in improving patient outcomes for persons with severe orthopedic trauma and enhancing both patient and provider satisfaction with overall care. The study will also determine the cost and cost-effectiveness of the intervention. Primary Hypothesis: Compared to standard treatment alone, access to the TCC Program plus standard treatment will result in lower rates of the composite outcome (i.e. positive for poor function, depression, and/or PTSD). Secondary Hypotheses: Compared to standard treatment alone, access to the TCC Program plus standard treatment will result in lower levels of pain and higher rates of return to usual major activity and higher levels of health related quality of life. In addition, both primary and secondary outcomes will correlate strongly with the intermediate outcome of self-efficacy.
The overall aim of this study is to develop an intervention that can help recovery in patients surviving severe brain injury but failing to fully recover. In particular, this multicenter project aims to (1) establish short-term efficacy of tFUS as a therapeutic to promote recovery in patients with prolonged DoC as compared to sham treatment, (2) establish dose-related safety and efficacy of tFUS as a therapeutic intervention in prolonged DoC patients and (3) explore preliminary predictors and biomarkers of susceptibility and response to thalamic sonication.
