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.
This study aims to assess the comparative effectiveness of the Hall technique (HT) and the conventional technique (CT) for placing Stainless Steel Crowns (SSCs) in primary molars with approximal caries.
Chronic Kidney Disease (CKD) is recognized as a leading health problem globally. It is associated with multiple consequences such as cardiovascular diseases, infections, reduced cognitive function, and higher mortality rates. In Qatar, it is estimated that 13% of the population suffers from CKD. Management of CKD is associated with polypharmacy (the use of multiple medications), which burdens the patients and leads to adverse health and economic outcomes. As documented by previous studies, CKD setting is associated with a high medication burden, which leads to non-adherence, reduced quality of life, and other negative sequelae. These consequences can be minimized or averted by implementing a deprescribing program. Deprescribing is defined as the supervised process of intentionally stopping a medication, altering the dose or introducing a safer alternative to improve a person's clinical and quality of life outcomes. Previous deprescribing initiatives in inpatient and outpatient hospital settings were successfully implemented. In general, there are limited deprescribing initiatives in CKD settings. There is a need to provide evidence of the impact of deprescribing programs on improving clinical and economic outcomes in this setting. In Qatar, there is no evidence of the effectiveness of implementing deprescribing programs in clinical settings. Therefore, we have built a team of researchers, clinicians, and stakeholders, and initiated a collaboration with deprescribing experts to fit into the Qatar healthcare system. This project aims to initiate a deprescribing multidisciplinary team and to evaluate the impact of providing such services on the clinical and economic outcomes among CKD patients in Qatar using a randomized controlled trial approach. The findings could have a potential positive impact on the professional practice and patient safety represented by health and economic outcomes.
SGLT2 inhibitors are oral anti-diabetic medications that were found to improve cardiorenal outcomes in patients with type 2 diabetes mellitus (DM), chronic heart failure with reduced and preserved ejection fraction, and chronic kidney disease. Recent evidence suggested that the use of SGLT2 inhibitors resulted in a significant reduction in atrial fibrillation (AF) over a mean follow-up duration of 2.6 years. Given the possible AF protective benefit with SGLT2 inhibitors use.
The Phase 3 pivotal study is designed to evaluate the efficacy and safety of RZ358 for the treatment of congenital hyperinsulinism (HI) as add-on to standard-of-care (SOC) therapy compared to SOC alone over 24 weeks and to evaluate the longer-term safety and efficacy of RZ358 during a subsequent open-label extension (OLE) period.
This is a clinical trial to assess the treatment outcomes of pulpotomy in vital primary molars diagnosed with symptomatic irreversible pulpitis. Pulpotomy is a more conservative treatment option over the conventional pulpectomy treatment. Compared to pulpectomy, pulpotomy is a technically simpler procedure, less time consuming, easier for young patients to tolerate, and retains the proprioceptive sensation of the tooth - all important advantages when treating young children.
This is an open label randomized controlled trial with two parallel groups to compare the effects of early initiation of oral diet to reduce the post-operative fasting time in adult patients undergoing cardiac surgery.Primary Objectives: - To assess the impact of early and conventional diet on post-operative nausea and vomiting by calculating the simplified PONV (post-operative nausea and vomiting) impact score of patients after cardiac surgery, with a score >5 indicating clinically significant PONV. - To study the impact of early versus conventional diet on gastrointestinal function by estimating the difference in timing of the first bowel movement in patients following cardiac surgery. Secondary Objectives: - To evaluate the effects of early versus conventional diet resumption on length of ICU stay among the patients following cardiac surgery in days. - To compare the satisfaction levels of patients by visual analogue scale who resumed their oral diets early versus conventionally following cardiac surgery. The estimated sample size of 196 patients with routine post operative recovery after cardiac surgery will be randomized into early (interventional) and late (control) diet groups. Researchers will compare the early diet group with late diet group to see the effects.
Specific Aim 1: To determine the knowledge, attitude, and practice (KAP) of PHCC physicians regarding appropriate prescription of antibiotics in the outpatient setting. Hypothesis 1a: PHCC physicians will have adequate theoretical knowledge regarding use of antibiotics for upper respiratory tract infections. Hypothesis 1b: Despite adequate theoretical knowledge, fear of complications of untreated infection and patient demand and expectations will drive inappropriate antibiotic prescription for upper respiratory tract infections Specific Aim 2: To test the effectiveness of a comprehensive multi-component intervention in a cluster randomized trial upon rate of antibiotics prescription for upper respiratory tract infections in individuals aged > 2 years presenting to primary care by PHCC physicians Hypothesis 2: Compared with a single intervention, a comprehensive multi-component intervention package will be associated with a significant reduction in inappropriate antibiotic prescription. Investigators will conduct this study in the Primary Healthcare Center (PHCC) setting in Qatar. Investigators will identify four large PHCCs from the existing active centers. The study has 2 parts. Part 1 corresponds to specific aim 1 and comprises of a KAP survey which will be carried out in all four PHCCs and will include all physicians. Part 2 corresponds to specific aim 2 and is a cluster randomized clinical trial in which Investigators will randomize the four PHCCs into two groups. First group (2 PHCCs) will receive training in appropriate documentation of infections and antibiotics prescription and will continue to provide usual care. Second group (2 PHCCs) will receive the comprehensive multi-component intervention, which consists of four elements: 1. Option for deferred prescription fulfilment; 2. Education of staff regarding appropriate uses of antibiotics, 3. algorithm-driven decision support tool, 4. Feedback on individual and group performance.
Carbohydrate counting is an essential component of diabetes management in both adults and children, and together with an intensive insulin plan and increased blood glucose monitoring was associated with lower HbA1c. Carbohydrate counting is perceived as one of the most burdensome tasks in T1D and is frequently done inconsistently and with poor accuracy A recent analysis confirms that MiniMed™ Advaced Hybrid closed loop (AHCL) system is designed for optimal performance with meal announcement. Nonetheless, when meals containing < 80 grams of carbohydrates are consumed with announcement of meals at will, there is a slight reduction in the number of daily boluses with no decline in glycemic control, yet markedly less diabetes related distress and improved treatment satisfaction TIR of 78.1% in unannounced meals compared with 78.8% with announced meals .
HER2-low Breast cancer (BC) has emerged as a new subtype of BC with distinct clinical, pathological, and prognostic features. Little is known about the prevalence of the HER2-low subtype in HER2-negative patients, and previous reports showed variations in the criteria used to define the HER2-low subtype. Besides, data on the clinical features and prognosis of HER2-low patients are limited, and it is still unclear whether HER2-low BC has a prognostic value. Identifying the prevalence and clinical features of HER2-low BC can help establish a more accurate and reproducible definition of HER2-low BC. In the Gulf Cooperation Council (GCC) region, BC is the most common malignancy in women and still poses a significant burden on healthcare resource utilization, moreover, there is only one record for reimbursed HER2 IHC status, categorized as HER2-positive and HER2-negative. It is important to understand the prevalence, clinical features, and outcomes of HER2-low in BC patients from the GCC In this retrospective, non-interventional, multicenter study, the aim to describe the prevalence of HER2-low BC among the current HER2-negative BC population using rescored HER2 IHC samples. The local treatment patterns and the outcomes will be analyzed using the information abstracted from the corresponding medical chart review. The study will cover the GCC region countries (United Arab Emirates [UAE], Saudi Arabia, Qatar, Kuwait, and Oman)
A significant proportion of patients who are intubated for trauma-related injuries, will fail the extubation process. This means that, when the decision has been made to remove the endotracheal tube, a certain proportion of these patients will require the endotracheal tube to be re-inserted. Global estimates for the rates of re-intubation range from 5-15% of all patients who have had attempted extubation on Intensive Care Units. The exact figures for intubated victims of trauma are not available. Re-intubation is associated with increased intensive care and hospital length of stay, increased morbidity, and the physical risks to the patient inherent with the intubation process. There is also some evidence that the rates of tracheostomy are higher in patients who have failed extubation. A number of interventions have been developed to help prevent extubation failure. Non-invasive ventilation and high-flow nasal oxygen are routinely employed in practice. However, there have been no specific studies of these interventions in TICU patients. High-flow nasal oxygen therapy (HFNO) has emerged over the last decade as a viable adjunct in the management of patients suffering from, or at risk of, hypoxemic respiratory failure. Within the intensive care unit settings, HFNO has been studies in terms of preventing intubation, but it has been evaluated more often in terms of preventing extubation failure. Our study aims to answer the question of whether HFNO is effective at preventing extubation failure in intubated and ventilated victims of traumatic injuries. Previous studies on the same subject, are not based on unequivocal, robust RCTs with low risk of bias. Our primary outcome measure is re-intubation rates and secondary outcome measures are CO2 accumulation rates, atelectasis rates, nutrition status within first 24 hours post extubation, and post - extubation rates of vomiting. Ours will be a prospective, randomized clinical control study. There will be three arms to the study: a control arm, and two intervention arms. Randomization will be done on a permuted block basis. The control arm will be patients receiving standard oxygen therapy, and the intervention arms will be either High Flow Nasal Oxygen Therapy or Non-invasive Ventilation via mask. We propose that, when compared with either face-mask O2, NIV (CPAP), HFNO administered continuously for 24 hours post extubation of trauma patients on ICU, will result in better patient-related outcomes.
