There are about 212 clinical studies being (or have been) conducted in Qatar. 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.
Thirty seven percent of adult male population smoke cigarettes in Qatar. The Global Youth Tobacco Survey also stated that 13.4% of male school students aged 13 to 15 years in Qatar smoke cigarettes. Smoking cessation is a key to reducing smoking related diseases and deaths. Health care providers are in an ideal position to encourage smoking cessation. Pharmacists are the most accessible health care providers and are uniquely situated to initiate behavior change among patients. Many western studies have shown that pharmacists can be successful in helping patients quit smoking. Studies demonstrating the effectiveness of pharmacist delivered smoking cessation programs are lacking in Qatar. This proposal aims to test the effect of a structured smoking cessation program delivered by trained ambulatory pharmacists in Qatar. A prospective, randomized, controlled trial will be conducted at 8 ambulatory pharmacies in Qatar. Participants will be randomly assigned to receive a 4-session face-to-face structured patient-specific smoking cessation program conducted by the pharmacist or 5 to 10 minutes of unstructured brief smoking cessation advice given by the pharmacist. Both groups will be offered nicotine therapy if feasible. The primary outcome of smoking cessation will be confirmed by exhaled carbon monoxide test at 12 months. If proven to be effective, this smoking cessation program will be considered as a model that Qatar and the region can apply to decrease smoking burden.
The purpose of the study is to compare the effect of two rehabilitation protocols with different emphasis on eccentric exercises after acute hamstring muscle strain injuries on the time to return to sports (RTS) and the rate of re-injuries in male athletes. The hypothesis is that the addition of early eccentric hamstring exercises being performed at longer muscle-tendon length towards end range of motion alter the outcomes RTS and re-injuries in a rehabilitation protocol after acute hamstring muscle strain injuries.
* Background: Despite extensive use, to the best of our knowledge, no trial has simultaneously compared the three currently used erythropoietin stimulating agents (ESAs) in a prospective manner, in treatment of anemia of end stage renal disease (ESRD) patients. * Patients and Methods: All haemodialysis patients in Qatar who were treated with short acting Epoetin alfa or beta were screened. Eligible patients were randomized, either to continue on the previous regimen of Epoetin, or to receive Darbepoetin alfa or continuous erythropoietin receptor activator (C.E.R.A) for a total period of 40 weeks. All groups were assessed at the end of the study for safety and efficacy parameters.
The purpose of this study is to learn about the effects of smoking shisha on the lungs, when compared to the effects of smoking cigarettes or of not smoking. The investigators hope to learn more about how shisha smokers should be monitored and treated once diseased.
With the assessment of the healthy vs. diabetic and pre-diabetic Qatari population the investigators intend to measure the changes in DNA methylation and gene expression in blood monocytes and lymphocytes attributed to diabetes, and to evaluate whether theses changes are persistent or can be reversed by improving diabetes control.
Sepsis is a major global health problem, leading to substantial morbidity and mortality despite medical care. The initial diagnosis of sepsis is a clinical challenge, as it is based on nonspecific systemic criteria. Excessive endothelial activation is a cardinal feature of sepsis and contributes to microvascular leak, edema, circulatory shock and organ failure. Activated endothelial cells shed endothelial microparticles (EMPs) which can be measured in plasma and are found at low levels in healthy subjects. Elevated EMPs have been reported in sepsis, but whether their effect is beneficial or deleterious is unclear. In this context, we hypothesize that circulating EMP levels can be assessed as a biomarker differentiating sepsis from non-sepsis critical illness. This may also suggest that EMP levels correlate with 30-day mortality. We propose to measure circulating EMPs at ICU admission in subjects with suspected sepsis. Final diagnoses will be adjudicated using standard criteria and 30-day mortality ascertained. Subjects determined not to have sepsis will serve as the control group. EMP levels will be correlated with diagnosis to ascertain the utility of EMP levels as a diagnostic biomarker for sepsis. For those subjects with proven sepsis, EMP levels will be correlated to 30-day mortality to assess EMP level as a prognostic marker in sepsis.
A randomized clinical trial to check the antipyretic efficacy of oral and intravenous paracetamol and intramuscular diclofenac sodium in patients presenting with fever to emergency department.
The purpose of this study is to evaluate the therapeutic benefit of utilizing complex growth factor preparations (Platelet Rich Plasma (PRP) in the management of acute hamstring injuries. The hypothesis is that the time to return to sport is shorter in the patient group treated with Complex Growth Factor Preparations (PRP) in combination with exercise therapy in comparison with 2 control groups: - the patient group treated with Platelet Poor Plasma (PPP) injections in combination with exercise therapy (control injection AND usual care). - the patient group treated with exercise therapy (usual care)
This prospective, observational study will evaluate the efficacy, safety and tolerability of RoActemra/Actemra (tocilizumab) in patients with moderate to severe active rheumatoid arthritis who have had an inadequate response or are intolerant to one or more conventional disease-modifying anti-rheumatic drugs. Data will be collected from patients initiated on RoActemra/Actemra treatment according to the local label at baseline, Weeks 4, 12 and 24, and at 3 and 6 months after the last dose of study drug.
This multicenter study will evaluate the correlation of interleukin 28B (IL28B) genotypes with disease characteristics and demographics in treatment-naïve and treatment-experienced chronic hepatitis C patients, including patients with HIV co-infection. There will be a single study visit for testing.
