There are about 175 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.
A high prevalence of diabetes has been reported in Qatar with nearly 23% population suffering from the pandemic, thereby increasing the associated healthcare cost. Low compliance with exercise and physical activity in patients with diabetes increases foot risk complications, deteriorates health, and further increases economic costs. This is particularly true among patients with diabetes who are undergoing hemodialysis (HD) process. Exercise interventions have been shown to improve mobility and balance, reduce the incidence of falls, and improve peripheral blood flow, which is essential to reduce foot problems and peripheral arterial disease. However, uptake of exercise programs for individuals who are undergoing HD treatment has been limited. The three main factors limiting uptake and adherence among HD patients are time availability, post-dialysis fatigue, and transportation to exercise programs, which are usually offered in rehabilitation departments or cardiovascular centers but not in nephrology departments or in free-standing dialysis clinics. Many of these patients visit clinics 3 times a week to receive hemodialysis, providing an optimal opportunity for intervention. Thus the investigators are proposing an innovative intervention based on plantar electrical stimulation treatment during HD (3 times per week) to enhance balance and quality of life while reducing the risk of peripheral arterial diseases and diabetic foot ulcers, which are highly prevalent among people with diabetes and chronic kidney disease. This interdisciplinary study is based on preliminary studies, in which the investigators demonstrated that regular plantar electrical stimulation is an effective and practical therapy to enhance motor performance and plantar sensation in patients with diabetes. The scientific premise of the proposed intervention has been also supported by literature as well as three systematic reviews suggesting the effectiveness of electrical stimulation to reduce pain, improve balance, improve skin perfusion, and improve plantar sensation. In the context of this study, the investigators propose to bring an innovative technology based on an FDA-cleared bio-electric stimulation technology (BEST®) microcurrent platform, named Tennant Biomodulator® (Avazzia Inc., Dallas, TX, USA), which is a transcutaneous electrical nerve stimulator (TENS) and has been designed for symptomatic relief and management of chronic pain. However, the system was modified to provide electrical stimulation to the plantar area via two electrodes placed on the hind and forefoot area instead of the leg. The device has a 60-minute run cycle after which it automatically turns off. In the context of a previous study funded by QNRF, the investigators developed and tested 50 electrical stimulation units (which will be used in the context of the study), including 25 active systems and 25 placebo systems. The placebo systems are similar to active systems in the appearance and functioning of lights and indicators. However, they were programmed not to provide any electrical current. In a preliminary study, the proof of concept of this revised technology was tested in the context of enhancing balance and skin perfusion in ambulatory patients with diabetes and peripheral neuropathy. In the context of this study, the investigators plan to translate this technology for routine treatment during HD sessions for patients with diabetes who are undergoing regular HD treatment. Using a double-blinded randomized-controlled model, the investigators will validate the effectiveness of this technology to enhance balance, reduce pain, and improve skin perfusion. One hundred (n=100) HD volunteers with diabetes will be recruited and randomized to either intervention (n=50) or control (CG: n=50) group for the purpose of this study. Plantar electrical stimulation will be provided during HD sessions, 3 times per week and for 12 weeks. Outcomes will be assessed at baseline, 6 weeks, and 12 weeks to examine the effectiveness of the proposed intervention to enhance balance, improve quality of life, and improve lower extremity skin perfusion among HD patients with diabetes. This proposal is in line with Qatar National Priorities Research goals and if successful the result will open new doors to managing diabetes and kidney failure. In a setting where no therapeutic agents or interventions effectively address poor balance and loss of protective sensation among HD patients with diabetes and where affected individuals life with a heightened risk of developing a debilitating foot ulcer and quite possibly a disabling amputation, the potential impact from the plantar electrical stimulation system may offer the potential for significant clinical benefit, with very low risk, and with ease of implementation in routine care application for patients who are undergoing HD treatment.
This randomized controlled study will enroll the eligible patients to either the Buzzy device arm or to the EMLA cream arm as a standard therapy. This will be done with concealment; however, blinding will not be practical. Will include 300 participants with 150 in each arm in Al Saad pediatric emergency. The research nurse will use a known valid and reliable measurements scales for the pain and anxiety. The data will be recorded with timing in a prepared form, The SPSS 22.0 and Epi-info soft wares and appropriate statistical tests will be used and will consider P value of <0.05 is statistically significant. The investigators are anticipating a Buzzy device effectiveness to be not less than the EMLA cream but the rapidity of effectiveness in buzzy device of around one minute compared to 30-45 minutes of EMLA cream will be an important outcome in a busy emergency department.
The in-utero exposure of acute viral infection in some instances is proven to have short- and long-term neonatal effects during the postnatal and childhood period and the Zika virus, measles, mumps, and rubella are few examples. COVID-19 is caused by a novel coronavirus strain of unknown consequences. The main purpose of this registry is to collect baseline data and help to establish future studies and hypothesis generation. In addition, we will be exploring the psychological impact of COVID-19 on women during the pregnancy and postnatal period. Stress and anxiety level are increased with potential adverse pregnancy and/or neonatal outcomes especially during an infectious disease outbreak. In fact, COVID-19 is associated with adverse maternal and neonatal outcomes resulting in increased levels of stress and anxiety. In addition, women during the pregnancy, peripartum, and postpartum period are at increased risk of depression. A risk that has been aggravated by social and physical isolation. Indeed, the social and physical isolation, a critically needed measure to stop the virus transmission, resulted in increased stress and depression levels and adversely affecting the mental and physical health of both the mother and the baby.
The study is intended to estimate the proportion and clinical management of people with type 2 diabetes having atherosclerotic cardiovascular diseases or who are at high risk to develop atherosclerotic cardiovascular diseases. Participants will be asked to give information about their health. Partipants will continue normal way of life and will not get any medication other than those prescribed to them by the doctor. The study will last for about 6 months.
The overarching aim of this project is to investigate the role of custom foot orthotics in a 'return to performance' framework as the ultimate part of the 'return to sport continuum'. The aim of this particular study is to investigate the effect of Custom Foot Orthotics (CFO) made from different materials on Running Economy (RE). Well trained recreational athletes (volunteers) will present to a physiology lab for a familiarisation running session where standard measurements (e.g. height, weight, shoe size, training history, foot shape) will be recorded. During this initial visit, our volunteers will also perform an incremental running test to determine the individual ventilatory threshold (VT). This will allow the use of individual speeds of a relative equal intensity that which will be used during the experimental session. A full explanation of the experimental procedures will be given and trialed. This session will last about 1 hour. For the experimental session (minimum of one week after the incremental test and receiving the custom-made orthotics), our volunteers will report to the same lab minimal 4 hours post prandial, having done no strenuous exercise for 12 hours before data collection. After a 10-minute warm up, Participants will run four 6-minute trials (four footwear conditions) with plenty of rest (5 minutes) between running trials to recover and answer short surveys on footwear comfort and readiness to start the next session. Also actual sprint performance will be tested. After a 10-minute general and sprint specific warm up twelve 5-second all out sprints (3 sprints per condition) with 4 minutes recovery between each sprint will be performed. This session will last about 2 and a half hours. The volunteers will run in four different footwear conditions: standardized running shoes + original liner of the sport shoe standardized running shoes + a custom-made orthotic from an EVA/TPU material standardized running shoes + a custom-made orthotic from an EVA material standardized running shoes + a custom-made orthotic from an TPU material
Echocardiographic measurement of inferior vena cava (IVC) collapsibility index (CI) with automated software analyses has been introduced. This study aims to assess the accuracy of IVC-CI (caval index) measurements as well as the ability to track fluid responsiveness (FRes) over time comparing the automated echocardiographic method with the pulse pressure variation (PPV) technique and the manual echocardiographic method in cardiac surgery patients.
Coronavirus disease 2019 is a novel viral disease caused by the Severe Acute Respiratory Syndrome Coronavirus 2 virus. The original cases occurred in Wuhan, China, in December 2019 and rapidly spread to other areas worldwide, constituting a pandemic with unimaginable health and economic consequences. the World Health Organization elevated the disease to the category of a pandemic on March 11, 2020. In children, the reported mortality rates were far below 1%, while in people above the age of 70 years it was above 5% or higher. So, in this retrospective study, the investigators describe the clinical features and outcomes of children with chronic kidney diseases who were diagnosed with Severe Acute Respiratory Syndrome Coronavirus 2 infection at pediatric centers in Doha from 1st March 2020 till January 20th, 2022. This review looks into the literature on pediatric patients with chronic kidney diseases to verify whether they were more prone to developing more severe symptoms when diagnosed with Coronavirus disease 2019 compared to children without chronic kidney diseases and adults with chronic kidney diseases, and the Prevalence of COVID-19 infection between patients with chronic kidney diseases, and the role of COVID-19 infection in increasing the relapses and deterioration of chronic kidney diseases.
Colchicine acts upstream in the cytokines cascade by inhibiting the NLRP3 inflammasome while IL-6 receptor antagonists (tocilizumab) block the end result of the cytokines cascade. Hence, adding colchicine to tocilizumab with the aim of blocking the early and end products of the cytokines cascade, might reduce the risk of developing cytokine storm and hence the need for invasive mechanical ventilation and eventually death. Therefore, investigators aim to conduct an open-label randomized controlled trial to evaluate the efficacy and safety of adding colchicine to tocilizumab among patients with severe COVID-19 pneumonia in an attempt to reduce the rate of invasive mechanical ventilation and mortality. Investigators will include patients with severe COVID-19 pneumonia and already received tocilizumab according to local protocol. Enrolled patient will be then randomized in 1:1 to colchicine versus no colchicine. Patients will be followed up until discharge or for 30 days, whichever comes first. Data will be collected from electronic medical profiles. The primary efficacy outcome will be rate of invasive mechanical ventilation and will be determined using Cox proportional hazard model.
Background and Aim. The new and advanced hybrid closed loop (AHCL) system MiniMed 780G automatically adjusts basal insulin delivery in addition to automated bolus corrections, based on continuous glucose monitoring (CGM) readings, to offer protection against both hyperglycemia and hypoglycemia. The objective of this study is to evaluate whether a simplified approach for patients' follow up using preset of pump settings and a simplified meal announcement, followed by minimal interaction can achieve similar glycemic control of AHCL system MiniMed 780G with Guardian Sensor 4 than a regular protocol that is currently used in adolescents with Type 1 Diabetes (T1D). Methods. This study is Randomized Clinical Trial, two arm, single-center, clinical investigation in subjects with type 1 diabetes on AHCL insulin pump in a period of 3 months. A total of 34 individuals (age 12-18 years) will be enrolled to reach 30 individuals who will complete the 3 months study. Participants will be randomized in two groups: Group 1, Regular Clinical Protocol, 17 participants and Group 2, Simplified Clinical Protocol, 17 participants. All patients will be recruited during the regular clinic visits to the outpatient Endocrine Clinics at Sidra Medicine in Doha. Patients will be chosen on a first-come first-served basis. Inclusion criteria: Clinical diagnosis of type 1 diabetes, , Age 12-18 years, Basal Bolus therapy >8.0 units per day. Exclusion criteria: Diabetic Ketoacidosis (DKA) in the 6 months prior to screening visit. The initiation protocol consists of four stages: HCL system compatibility assessment, HCL system training, Manual Mode Start and Auto Mode start. Patients will have 7 visits in a period of 3 months after initiation of insulin pump therapy. Pump initiation: Group 1, Finetune ICR, Target 100 or 110 mg/dl and AIT: 2-3 hour and Group 2, Carb Ratio by formula 360 / TDD, ICR 8-10 (TDD 40-60), ICR 5-7 (TDD >60), Target 100 mg/dl, AIT: 2 hours with fixed meals Results. No group difference in Time in Range (TIR) (70-180mg/dl) > 70% and HbA1c < 7.5% in a period of 3 months after initiation of AHCL. Conclusion. Conclusions will be drawn on completion of the study and evaluation of the results.
Patients with blood cancers and those who received a bone marrow transplant frequently have low circulating white blood cell countS. Fever in patients with low white blood cell count requires early appropriate antibiotic treatment to prevent complications including death. Bacteria have increasingly become more resistant to existing antibiotic options. Ceftolozane-tazobactam is a newer type of antibiotic that has been shown to be safe and effective in infections caused by several types of resistant bacteria that can cause serious infections in individuals with low blood count. This study aims to examine the effectiveness of this antibiotic in these types of patients. Patients with blood cancer and those who have received a bone transplant will be offered the option to join this study if they develop unexplained fever. If informed consent is granted, they will receive ceftolozane-tazobactam on top of the usual care that such patients receive. The patients will then be followed very closely to check their response to the treatment and if they develop any untoward events. The study will include 164 patients over an estimated 2 year period. The study is funded by Merck & Co, the company that manufactures the study antibiotic. However, Merck & Co. will not be involved in the actual running of the study, the collection of the study results or their analysis and interpretation. The study protocol has been reviewed and approved by an independent research oversight committee.
