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.
A highly pathogenic human coronavirus causing respiratory disease emerged in Saudi Arabia in 2012. This viral infection termed Middle East respiratory syndrome coronavirus (MERS-CoV) is associated with high mortality rate in approximately 36% of reported patients. The World Health Organization (WHO) reported 1,374 laboratory-confirmed worldwide infections, including at least 490 related deaths, from September, 2012, to July 24, 2015.2 The higher incidence of MERS-CoV infections in Saudi Arabia may be related to multiple factors, including seasonality, increased proactive screening, poor infection control measures, low relative humidity, and high temperature. Infected patients with MERS-CoV usually have abnormal findings on chest radiography, ranging from subtle to extensive unilateral and bilateral abnormalities. MERS progresses rapidly to respiratory failure, in approximately 2/3 of infected patients, which has a high mortality rate, particularly in immunocompromised patients. Extracorporeal membrane oxygenation (ECMO) has emerged as a rescue therapy in patients with refractory hypoxemia during the H1N1 epidemic.The use of veno-venous (VV)-ECMO provides respiratory support for patients with respiratory failure, whereas the use of veno-arterial (VA)-ECMO could be helpful in those with cardiorespiratory failure.10 However, the survival rate of the infected patients with H1N1 who required the use of ECMO varies considerably among the Caucasian and Asian countries (90% survival in Sweden and 83% in the UK13 vs. 35% in Japan). This large discrepancy could be explained with lack of satisfactory equipment, therapeutic guidelines, training of staff, and effective systems allowing patient transfer to the dedicated ECMO centres. Guery and co-investigators described the use of ECMO in two French patients with cardiorespiratory failure secondary to MERS-CoV infection.This has been extended for treatment of refractory hypoxemic respiratory failure during the Saudi MERS-CoV outbreak.
150 children aged between five and seven years presenting for the first dental visit, whose parents consented to participate in the study were selected from patients reporting to the dental clinics Riyadh Colleges of Dentistry and Pharmacy using convenience sampling. Pulse rate for each patient was measured at different clinical situation starting from patient parent separation until end of appointment using a pulse oximeter, Data which collected was statistically analyzed using appropriate statistical analyses using SPSS ver.19 data processing software.
The TOPP-2 registry is an international, non-interventional, prospective registry including children and adolescents newly diagnosed with pulmonary hypertension (PH) to gain further insights in the disease course and long-term outcome of PH in childhood. Patients will undergo clinical assessments and receive standard medical care, as determined by treating physicians in their daily clinical practice. The TOPP-2 registry is specifically designed to capture the variables that have been proposed as treatment goals in PePH and the reasons for changes in treatment strategy. The TOPP-2 registry uses the new clinical classification of PH as outlined at the 5th World Symposium for Pulmonary Hypertension (WSPH) in Nice 2013 and includes new characterizations for children with PH. The registry is planned and implemented under the scientific leadership of the Association for Pediatric Pulmonary Hypertension (PePH), independently from the financial sponsors. All enrolled patients will have a follow-up period of 18 months.
The purpose of this study is to evaluate the effects of term infant formula containing high 2-palmitic vegetable oil on stool composition, stool characteristics and gastrointestinal (GI) Tolerance.
RE-COVERY is a large, multi-national, multi-center observational study based on new data collection. The study will enroll and characterize patients within 30 days of being diagnosed with an acute DVT and/or PE. The study has two main objectives. Objective 1 will characterize the DVT / PE patient population. All patients with a DVT and/or PE will be enrolled for cross-sectional characterization of the VTE patient population. Objective 2 will compare the safety and effectiveness of dabigatran etexilate regimens for treatment of VTE in comparison to VKA regimens. Patients treated with dabigatran etexilate or VKA will be followed up for the occurrence of outcome events for up to one year.
Prospective, single arm, multi-center, observational, post market study to document the clinical and device performance outcomes of the Evolut R system used in routine hospital practice in a large patient cohort for the treatment of symptomatic native aortic valve stenosis or a stenosed, insufficient, or combined surgical bioprosthetic valve failure necessitating valve replacement.
The study will enroll patients presenting with claudication, or critical limb ischemia (Rutherford Category 3- 5) and an angiographically significant (≥ 70%) native artery lesion appropriate for angioplasty that is below the knee. Subjects will be treated with the Lutonix Drug Coated Balloon (DCB) carrying the CE Mark per current IFU and followed clinically for a minimum of 2 years.
This study aims to test the hypothesis that there was a relationship between the consumption of energy drinks and the manual dexterity skills of final year dental students. Identification of baseline caffeine consumption and selection of sample Baseline caffeine consumption will be identified by distributing the caffeine consumption questionnaire to all the final year students of the Riyadh Colleges of Dentistry and Pharmacy. The study will recruit 60 students who are moderate caffeine consumers. To avoid the confounding effect of nicotine consumption, the study will only recruit non-smokers .female candidates taken oral contraceptives and Subjects with any history of renal disease will be excluded. All subjects will be required to prepare a box 2mmx2mmx2mm using a high speed handpiece (NSK, Japan) and a no.330 cutting bur. Each participant will be allowed two attempts to cut the cavity in each test both cavities will be selected for assessment. The ability of the participants to reproduce the dimensions (2mmx2mmx2mm) and the time taken to complete the task will be used as criteria to evaluate dexterity. The participants will be required to perform the test before and 30 minutes after energy drink exposure. Energy Drink Exposure Subjects will be given 330ml of an energy three hours after the last meal in the other hand the control group will be receiving a placebo drink . Dexterity outcomes will be compared before and after exposure to the energy drink using the paired t test. Outcomes will be compared between different groups and different time intervals using the two way, multiple measures ANOVA. All data will be analyzed using the SPSS ver.21 data processing software.
This study will investigate whether switching symptomatic COPD patients from a fixed-dose combination of salmeterol/fluticasone 50/500 µg b.i.d. to a fixed dose combination of QVA149 110/50 µg o.d. leads to improved lung function and airflow. It will also assess the effect on symptom burden, breathlessness, and use of rescue medication after this switch.
A Multi-Centre, Phase II, Randomized, Double-Blind, Placebo-Controlled Study to investigate Efficacy and Safety of Sevuparin Infusion for the Management of Acute Vaso-Occlusive Crisis (VOC) in Subjects with Sickle-Cell Disease (SCD).
