There are about 1320 clinical studies being (or have been) conducted in Saudi Arabia. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
This study is designed to investigate the presence and absence of abnormal heart muscle contractions during sickle cell crises. You will be asked to do echocardiography during and after your admission to the hospital. We will compare tow pictures and study the differences.
Some people develop the condition called acute respiratory distress syndrome (ARDS). This is a condition where the lungs have become injured from one of a number of various causes, and do not work as they normally do to provide oxygen and remove carbon dioxide from the body. This can lead to a reduced amount of oxygen in the patient's bloodstream. Patients with ARDS are admitted to the intensive care unit (ICU) and need help with their breathing by being connected to a ventilator (breathing machine). ARDS can lead to injury in other organs of the body causing other problems but also death. Over the past few years, reducing the size of each breath delivered by the ventilator in conjunction with the use of an occasional sustained deep breath called a "recruitment manoeuvre" have been used to try to prevent further damage to the lungs in people with ARDS. This ventilator strategy (termed the PHARLAP strategy) has been shown in a small research study to have some beneficial effects without causing any obvious harm, when compared to a current best practice ventilator strategy. The main beneficial effects of the PHARLAP strategy were to increase the amount of oxygen in the blood and to reduce markers of inflammation (the body reacting to a disease process) in the body. This study was too small to make a strong conclusion, so this study will be much larger and will assess whether patients who have developed ARDS are better off when we use the PHARLAP strategy. Three hundred and forty patients will be enrolled into this study in multiple ICUs across Australia and New Zealand. The study hypothesis is that the PHARLAP strategy group will have a higher number of ventilator free days at day 28 than the control group.
This multicenter, randomized, open label parallel-group study will evaluate the efficacy and safety of subcutaneous versus intravenous MabThera/Rituxan (rituximab) in combination with CHOP chemotherapy in patients with previously untreated CD20-positive diffuse large B-Cell lymphoma. Patients will be randomized to receive either MabThera/Rituxan 1400 mg subcutaneously or MabThera/Rituxan 375 mg/m2 intravenously on Day 1 of each cycle for 8 cycles, in combination with 6-8 cycles of CHOP chemotherapy. Anticipated time on study treatment is 6 months.
The purpose of this study is to assess whether the addition of a drug such as Magnesium sulphate while providing therapeutic hypothermia (or cooling) to babies who are asphyxiated at birth provides additional benefit to the babies' survival and outcome compared to cooling alone.
In Australia, blood for transfusion has a "use by" date of 42 days after collection. The actual age of blood given to patients depends on what is available at the time and the rate of usage. During the last decade, it has been reported that blood transfusion in patients admitted to intensive care was associated with an independent increase of mortality. Some research suggests that transfusion of fresher blood might help patients in the intensive care unit to reach a better recovery. This project will test whether patients who receive 'fresher' blood do better than patients who receive 'standard issue' blood.
The purpose of the study was to compare the safety and efficacy of two agents used in induction of labor Propess (Controlled release dinoprostone, PGE2, pessary) and Prostin E2 (Dinoprostone vaginal Tablet).
This is an observational, multi-center, international disease registry designed to collect longitudinal data and create a knowledge base that will be utilized to improve the care and treatment of patients with LAL Deficiency. Participation in the Registry by both physicians and patients is voluntary.
The Medtronic Market-Released DF4 Lead Imaging Study is a prospective, non-randomized study, multi-center clinical investigation. The purpose of this clinical investigation is to collect high quality medical images of the Medtronic Market-Released DF4 lead in the shoulder and heart. Images collected during the study will allow for lead design and testing processes better tailored to the implanted environment.
Non-alcoholic fatty liver disease (NAFLD) is the most common form of chronic liver disease. In the absence of chronic alcohol abuse or other liver diseases, NAFLD incorporates a wide spectrum of liver pathologies and is defined by fatty infiltration of the liver (simple hepatosteatosis). It can progress to non-alcoholic steatohepatitis (NASH) and later fibrosis, cirrhosis, and eventually some patients may develop hepatocellular carcinoma with or without cirrhosis. The exact cause of NAFLD is yet to be cleared and it is, therefore, an active area for research. The diagnosis of NAFLD is achieved through histological examination of liver biopsies (invasive), non-invasive markers using serum biomarkers and imaging techniques are still under development. Pathological diagnosis can be then subcategorized based on several scoring systems. More widely used are the Brunt Score or NAS (NAFLD activity score) and the Kleiner's modified NAS. Obesity is highly associated with NAFLD, as the epidemic of obesity has made NAFLD more prevalent. In addition insulin resistance has been linked to NAFLD and this is explained by the increased influx of free fatty acids (FFAs) into the liver. FFA undergoes either β-oxidation or esterification with glycerol to form triglycerides (TGs), resulting in an additional source of fat in the liver. Due to the strong association of NAFLD with obesity, weight reduction procedures are used for the management of NAFLD. In fact, this has been shown to be effective by several studies. However, other studies have reported liver deterioration after bariatric intervention. This conflict is what makes the effects of bariatric procedures a challenging field for further studies. Consequently in this study we are aimed to examine histologic, metabolic and liver function changes induced by the different therapeutic bariatric procedures.
The purpose of this study is to improve their outcome by either changing the chemotherapy drugs or giving them radiation therapy with concurrent chemotherapy, hoping that this will improve their outcome.
