There are about 211 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 purpose of this study is to document the pharmacological treatment strategies used in treatment naïve and previously treated relapsed/refractory iNHL/CLL patients in the Middle East and North African (MENA) region. This study will also record encountered tumor subtype and stage and the instituted pharmacological treatments, as well as assess the clinical outcomes of treatments.
Hypothesis: To identify new gene mutations that can be related to patients with idiopathic male factor infertility. Primary Objective: To detect possible genetic abnormalities in families with more than one sibling with male infertility. Secondary Objective: To evaluate using next generation DNA sequencing in cases of infertility
This protocol is designed to gather a small amount of blood for extraction of DNA for the study of the genetic basis of diabetes. The study population will include individuals with known diabetes, and controls without diabetes. Investigators aim to understand the genetics of diabetes, and will use the cells and serum from this blood to perform genotyping and gene expression studies of individuals with diabetes and relevant controls.
The purpose of the Optimize RV study is to determine the long-term effect of selective site pacing. Selective site pacing refers to which area of the right ventricle the lead is placed. The goal of select site pacing is to improve how the heart contracts when paced in the ventricle. By pacing in select sites, it is possible to better copy the natural pattern of contraction of the heart.
