Impact of Helmet Use in Preschool Children
Head InjuriesFacial InjuriesTo test the hypothesis if provision of helmet education and free helmet distribution will significantly increase helmet use in preschool children of low-income families compared to those children receiving helmet education without free helmet distribution; To test the hypothesis if helmet users in preschool children will significantly reduce head and facial injuries compared to those non-helmet users

Prevention of Acute Kidney Injury in Cardiac Surgery Patients
Kidney InjuryAcute kidney injury (AKI) has no uniform criteria, but is commonly defined as an increase in serum creatinine concentration by at least 25% from baseline. It occurs in 30% of patients following cardiac surgery, and at least 50% of patients with underlying renal insufficiency. Patients who have a reduced creatinine clearance pre-operatively are at the greatest risk of developing post-operative AKI. The purpose of the current study is to determine if intravenous hydration with either isotonic saline or sodium bicarbonate 150 mEq/L is effective at preventing post-operative AKI in patients with baseline kidney insufficiency and who are undergoing cardiac surgery using cardiopulmonary bypass. The study hypothesis is that an infusion of sodium bicarbonate 150 mEq/L will be more effective than isotonic saline in reducing the incidence of post-operative AKI in cardiac surgery patients with a preoperative glomerular filtration rate (GFR) less than 60 ml/min/1.73m2.

Reduction of Risk for Low Back Injury in Theater of Operations
Lower Back InjuryThe investigators will conduct a controlled clinical trial with U.S. Army soldiers training to become combat medics. The purpose of this study is to determine if a 11-week, high intensity exercise program targeting the low back muscles using specialized equipment will result in a 25% increase in low back muscular strength and endurance compared with a lower intensity general core stability exercise.

Effect of Exercise on Blood Coagulation in Persons With Chronic Spinal Cord Injury
Cardiovascular DiseaseSpinal Cord InjuryThe purpose of this study is to determine if exercise affects the clotting of blood (hemostasis). The effect of exercise on hemostasis will be determined in persons with spinal cord injury, a population reported to have an increased prevalence of cardiovascular disease (CVD). It is expected that this study will increase our understanding of CVD in persons with SCI, and it will eventually help reduce the occurrence of premature heart disease.

Risedronate for the Prevention of Osteoporosis in People With Spinal Cord Injury.
Acute Spinal Cord Injury.The purpose of this study is to find out if Risedronate works to prevent osteoporosis after spinal cord injury.

The Effect of Spironolactone on Acute Kidney Injury in Patients Undergoing Coronary Angiography...
Acute Kidney InjuryIHD1 morean interventional study to measure the possible effects of spironolactone ( an aldosterone antagonist) on the incidence of acute kidney injury after coronary angiography

Health Promotion and Cardiovascular Risk Reduction Among People With Spinal Cord Injury
Spinal Cord InjuriesThis study is a controlled pragmatic implementation study in clinical practice, with a primary focus on cardiovascular risk reduction through adherence to behavioral interventions related to physical activity and healthy diet.The intervention is interdisciplinary, multimodal and patient activating and uses the existing setting and work flows at the clinic, ensuring that the patients receive education about cardiovascular risk factors, physical activity and healthy diet through a systematic approach including targeted patient education.

Lung and Diaphragm-Protective Ventilation by Means of Assessing Respiratory Work
Diaphragm InjuryLung Injury2 moreThis study is designed to test a proposed strategy for lung- and diaphragm-protective ventilation (LDPV) in patients with acute hypoxemic respiratory failure. Ventilation and sedation will be titrated to evaluate whether it is feasible and safe within this patient population.

Erythropoietin Effect on Ischemic_ Reperfusion Injury in Coronary Artery Bypass Graft Surgery
Myocardial Ischemic Reperfusion InjuryThe aim of this trail is to assess the safety and therapeutic effects of single EPO intervention in different times during coronary surgery in changes of inflammatory response.

Initial Evaluation of the Cellie Coping Kit for Children With Injury
InjuriesThe purpose of this study is to assess the feasibility (fidelity, acceptability, implementation, cost) of the Cellie Coping Kit for Children with Injury as well as to determine the intervention's efficacy (mechanisms of action and health outcomes).
