The purpose of this study is to clinically evaluate the effects of a school-based behavioral intervention, CATCH Healthy Smiles, to reduce the risk of dental caries in a cohort of kindergarten through 2nd grade (K-2) children serving low-income, ethnically-diverse children,to determine the impact of CATCH Healthy Smiles on child behavioral, psychosocial, and environmental outcomes beginning in K through 2nd grade, compared to children in the control schools and to examine the extent to which the child behavioral, psychosocial, and environmental factors mediate the improvements in child caries risk.

Acute stroke afflicts nearly 700,000 patients in the US and is the number 3 cause of death. Only 2-9% of this large number is treated with t-PA if they arrive within 4.5 hours. An equally small percentage of patients with large vessel occlusion undergo thrombectomy. The thrombectomy patients may or may not receive t-PA. Some of these patients rarely receive intravenous GPIIB/IIIa inhibitors. Many lines of evidence suggest that GP IIb/IIIa inhibitors, a class of FDA approved potent platelet inhibitors that have been used extensively along with heparin for acute coronary syndromes (heart attacks) and unstable angina (chest pain), may be safe enough to give in these circumstances.

This is a first-in-human (FIH), multicenter, open-label Phase I dose escalation study to evaluate the safety and preliminary efficacy of the TT-01488 tablet, a non-covalent reversible BTK inhibitor, for the treatment of adult patients with B-cell malignancies. Read Less

The purpose of this trial is to evaluate if the use of Bone Morphogenic Protein(BMP)/Demineralized Bone Matrix (DBM) versus the use of autologous Iliac Crest Bone Graft (ICBG) will result in an increase in total cost effectiveness for patients undergoing alveolar bone graft (ABG) for Cleft Lip and Palate (CLP) and to see if patients who are treated with DBM/BMP will have reduced post-operative pain scores,reduced operative times,and similar rates of bone healing compared to conventional ICBG.

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 study investigates the efficacy of a reading comprehension intervention for English learners in Grades 6 and 7 with reading difficulties. Building on previous intervention studies conducted with students in Grades 4 through 8 over the past 10 years, the investigators utilize a longitudinal, double-cohort design utilizing a randomized control trial assigning students to supplemental reading intervention (RISE) or a no intervention "business as usual" (BAU) comparison condition (i.e., Cohort 1 - Years 1 and 2; 205 students in treatment and 205 in control condition; Cohort 2 - Years 3 and 4; 205 students in treatment and 205 in control condition; total 410 in each condition). Students in each cohort will be treated for 2 years (i.e., 6th and 7th grades or 7th and 8th grades). The primary outcome is reading comprehension. The investigators hypothesize that participants receiving the RISE intervention will outperform those receiving BAU instruction across reading-related elements, including word reading, fluency, and comprehension at end of year two of treatment.

Computer aided detection (CADe) algorithms have been developed to overcome human errors and assist endoscopists in detecting more polyps during colonoscopy. The aim of this study was to investigate the accuracy of the novel Pentax Discovery CADe system (Discovery-AI) against pre-recorded videos of colon polyps of various size, shape and pathology while using videos of normal colon segments as controls from two different institutes.
