There are about 88 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.
The primarily goal of the research is to better understand progression of disease in patients who present with an acute stroke to the Hamad General Hospital (HGH) stroke and Transient Ischemic Attack (TIA) clinic. The investigators are specifically interested in patients who have diabetes and have a stroke. The patients enrolled into the research will have detailed clinical evaluation and their imaging studies (MRI and Doppler) will be reviewed. After informed consent, subjects will be examined in the stroke Ward /TIA clinic upon recruitment, and later at less than 48 hours of recruitment (blood extraction and urine samples) and for follow up visits at 1 month+/-7 days (clinical evaluation and to extract blood and urine samples), at 3 months (telephonic conversation only) and at 1 year (clinical and repeat MRI brain). During the initial visit at the ward the investigators will collect serum and plasma for proteomic and metabolomic studies. These will be repeated at less than 48 hours and at 1 month+/-7 days. Investigators will test the effects of risk factors such as diabetes/stroke on the endothelial procoagulant and inflammatory state at onset and evaluate if best medical control leads to improvement in such markers.The repeated studies will determine if better management and presence of certain blood biomarkers can predict or translate to slower progression of disease and correlate it with clinical status.
Diabetes is one of the greatest challenges faced by healthcare services worldwide. It is associated with serious complications such as heart attacks, stroke, and peripheral artery disease as well as kidney disease, eye disease, and nerve dysfunction. Data from weight loss with bariatric surgery suggest that with the appropriate intervention, it should be possible to reverse diabetes and that the earlier the intervention occurs, the greater the chances of placing diabetes into remission. There is now a need to translate this knowledge into the medical care of younger patients with early diabetes who are overweight/obese. The aim of this study is to see if younger adult patients with overweight/obesity and type 2 diabetes who are participants in a programme incorporating a low energy diet and physical activity (lifestyle) will lower their weight, cardiovascular risk and improve their glycaemic control as compared to the usual care.
Diabetic kidney disease (nephropathy) develops in nearly 40% of patients with type 2 diabetes mellitus. Diabetic nephropathy is caused by damage to the small blood vessels in the kidneys due to uncontrolled blood sugar levels, which mean that the kidneys become less effective at filtering urine. This is associated with albuminuria (protein in the urine). Treatment with some drugs reduces the loss of albumin through the urine and delays disease progression. There is increasing evidence that vitamin D could also be important in management of diabetic kidney disease. The aim of this study is to investigate the efficacy and safety of a combined regimen of calcitriol (active vitamin D) and established drugs for diabetic kidney disease.
One of the most common post-operative deficiencies or complications of bariatric surgery is protein malnutrition. It may lead to many predicaments such as malnutrition, vitamin, micro- and macronutrient deficiencies that can lead to deleterious consequences. A protein-rich diet make a person feel satiety and thereby the consumption will be low in overall energy intake. The objectives of our study are. The aim of this study is to assess the effect of protein supplementation on changes in health parameters such as fat mass, muscle mass, weigh change, protein (total and albumin), Vit B12, Zinc and Magnesium, in Qatari patients post bariatric surgery. Our participants are Qatari aged 18-45 years males and females recruited from the bariatric surgery centers of 2 major HMC hospitals (HGH hospital) and will be randomized to receive either the protein supplement (treatment group) or a dietary advice (control group). All participants will be equally followed and monitored for 3 months and data on the above parameters will be collected, together with other population characteristics, at Baseline, 1 month and 3 month. Data will then be analyzed using the most up-to-date SPSS statistical package to assess the effect of protein supplementation on the parameters of interest. Statistical measures will be carefully chosen to properly assess the difference in the treatment (protein supplementation) effect compared with the control (Dietary advice). Investigators hypothesize that Patients receiving protein supplement (intervention group) Compared with patient not on protein supplement (placebo group) will maintain weight loss and other essential health parameters.
The Main purpose of this project to study the uptake pattern of FLT-PET and it is value in assessing the malignant hematopoiesis in MPN within the pediatric age group, in terms of diagnosis, staging and monitoring response to therapy. As well as, evaluating FLT-PET as a novel non-invasive technique in cases with MPN and its role in comparison to the standard bone marrow biopsy with regard to disease diagnosis, assessment of disease activity, detection of transformation, monitoring of treatment response and grading of fibrosis.Furthermore, we aim to study the association of FLT-PET uptake patterns with different genetic makeup (JAK2, CALR positive, MPL, or Triple negative disease) or allele burden in cases of Pre-PMF with the ability of FLT-PET to differentiate between Pre-PMF and ET. Although MPNs are diseases of elderly, MPN is diagnosed in younger age groups in a considerable number of cases. Since most of the available data as well as current WHO classification criteria emphases on the "average" MPN patients who range in age between 55 and 65 years. Less consistent data are available in the groups of patients presenting below this median age, such as children and younger adults which we're planning to reveal.
The main purpose of this project is to study the uptake pattern of FLT-PET in cases, and it is value in assessing the malignant hematopoiesis in cases of Pre-PMF and ET, regarding diagnosis, staging and monitoring response to therapy. Identifying different patterns of uptake in patients with Pre-PMF and ET in various clinical settings. Evaluating FLT-PET as a novel non-invasive technique in cases with Pre-PMF and ET, in comparison to the standard bone marrow biopsy about disease diagnosis, assessment of disease activity, detection of transformation, monitoring of treatment response and grading of fibrosis.Study the ability of FLT-PET to differentiate between Pre-PMF and ET. the investigators also aim to examine the association of FLT-PET uptake patterns with different genetic makeup (JAK2 (Janus kinase 2), CALR (Calreticulin), MPL (myeloproliferative leukemia protein), or Triple negative disease) or allele burden in cases of Pre-PMF and ET.
A prospective, multi-centre, epidemiological observational study designed to evaluate the prevalence of BRCA1 and BRCA2 (BReast CAncer gene) mutations in current and newly diagnosed ovarian cancer patients across different countries in the Gulf region. This study will also describe the epidemiological features for the disease for the enrolled patients.
Among patients with diabetes 35% suffer from chronic renal disease and may require dialysis or kidney replacement over time. Furthermore, in diabetics with end stage renal disease (ESRD) that require dialysis, the risk of foot complications and amputation is even more common, expensive, and devastating. Interestingly, even though incidence of foot ulcers in patients with dialysis has been reported to be same as with patients with history of foot ulcers; dialysis patients have significantly higher rate of foot amputation. The goal of this research is to incorporate an innovative virtually supervised non-weight bearing exercise in patients undergoing dialysis to reduce risk of fall and foot ulceration by enhancing lower extremity blood flow, joint perception and joint mobility. Diabetic patients on hemodialysis at Hamad Medical Company will be recruited and will be randomized to either intervention (IG) or control (CG) group and followed for 6 months. The intervention group will take part in a 4-week non-weight bearing exercise program twice per week at the hemodialysis clinic under the supervision of a qualified research staff member. This intervention includes interactive game-based exercises including repetitive ankle and foot movements. Wearable sensors will provide real-time visual/auditory feedback from foot and ankle position and allowed perception of motor-errors during each motor-action. The control group will be instructed to complete a supervised foot and ankle exercise without using sensor technology. Changes in balance, gait, and physical activity, incidence of foot problems will be compared pre- and post-intervention. In addition, the incident of falls, foot ulcers, and limb amputation up to 6 months post intervention will be documented. Investigators hypothesize that patients receiving sensor-based exercises will benefit more compared to group receiving conventional non-technology training in terms of improving functional performance and reducing incidence of foot problems, falls, and limb amputation.
