Clinical trials

The goal of this clinical trial is to learn whether an AI-powered carbohydrate counting educational platform can help parents of children with type 1 diabetes improve their carbohydrate counting skills and diabetes management. The study will include parents or primary caregivers of children aged 2-12 years with type 1 diabetes. The main questions it aims to answer are: * Is the AI-powered educational platform feasible, acceptable, and easy for parents to use? * Can the platform improve carbohydrate counting accuracy, parental confidence in diabetes management, and diabetes outcomes compared with usual education alone? Researchers will compare parents who receive access to the AI-powered carbohydrate counting educational platform plus usual diabetes education with parents who receive usual diabetes education alone to see whether the AI-supported approach provides additional benefits. Participants will: * Complete baseline assessments, including questionnaires and a carbohydrate counting test. * Be randomly assigned to either the AI-supported education group or the usual education group. * Use the assigned educational resources for 12 weeks. * Complete a follow-up assessment at 6 weeks and a final assessment at 12 weeks. * Provide information about their child's diabetes management, including HbA1c and glucose monitoring data. * Complete questionnaires about confidence, usability, and satisfaction with the educational support they receive. The AI platform is designed to provide educational support only and does not replace medical advice, insulin dosing decisions, or routine diabetes care provided by healthcare professionals.

This is a multi-centre, prospective, randomized, open-label controlled trial designed to evaluate the effectiveness of a flexible digital insulin dose calculator in children under 12 years of age with Type 1 Diabetes Mellitus (T1DM) managed with multiple daily injections (MDI). Participants will be stratified by continuous glucose monitoring (CGM) use and baseline HbA1c, and randomised to receive either standard care alone or standard care plus the insulin dose calculator tool for 6 months. The primary outcome is the change in HbA1c from baseline to 6 months. Secondary outcomes include CGM-derived glycaemic metrics (Time in Range, Time Below Range, Time Above Range, and Coefficient of Variation), total daily insulin dose (units/kg/day), healthcare provider contact frequency, and caregiver-reported usability and satisfaction. The study aims to determine whether the use of a structured digital decision-support tool improves glycaemic control and supports safer insulin dosing in paediatric patients with T1DM.

The goal of this clinical trial is to learn whether dapagliflozin can help manage weight gain caused by antipsychotic medications in people aged 16 years or older who are receiving antipsychotic treatment and have developed antipsychotic-induced weight gain. The main questions it aims to answer are: Can dapagliflozin reduce body weight as effectively and safely as metformin over the study period? How do dapagliflozin and metformin compare in their effects on body weight, body mass index, waist circumference, blood sugar, HbA1c, lipid profile, psychiatric symptoms, quality of life, medication adherence, and side effects? Researchers will compare dapagliflozin plus a common lifestyle program with metformin plus a common lifestyle program to see which treatment is more effective, better tolerated, and more acceptable for managing antipsychotic-induced weight gain. Participants will: Be randomly assigned to receive either dapagliflozin or metformin. Receive lifestyle advice, including dietary counselling, physical activity counselling, and behavioural support. Attend clinic visits at baseline, Week 12, and Week 26 for weight, waist circumference, blood tests, medication review, and other assessments. Receive telephone follow-up at Week 2, Week 6, and Week 18 to check medication adherence, side effects, tolerability, and lifestyle progress. Complete questionnaires and clinical assessments related to physical activity, quality of life, psychiatric symptoms, and treatment tolerability.

Investigating the efficacy of tranexamic acid (TXA) as a prophylactic agent in reducing postpartum haemorrhage (PPH) among patients undergoing cesarean section (CS) in SQUH: a prospective randomized controlled trial.

Background: Cardiovascular disease is considered one of the most prevalent diseases in recent times, and cardiac catheterization is widely used to diagnose and treat cardiovascular disease. However, patients often experience significant anxiety before the procedure due to fear of the unknown, potential complications, and concern about discomfort.Aim: To evaluate the efficacy of virtual reality technology to reduce anxiety and improve patient satisfaction, attitude, and usefulness in individuals undergoing first-time cardiac catheterization procedures in Oman.Method: A mixed-method randomized control trial will be used with approximately 120 patients from different tertiary hospitals in Oman. The experimental group will experience a virtual reality simulation of the catheterization process before providing informed consent, while the control group will receive the standard pre-procedure education. The Arabic version of the DASS-21 scale will be used to assess anxiety level pre- and post-intervention, while patient satisfaction will be measured through qualitative interviews with a subset of 10 participants.Result: ANOVA will be conducted to examine differences in anxiety and satisfaction scores between groups, and Pearson's correlation (r) will assess relationships between anxiety levels and satisfaction scores, while paired t-tests will be applied to compare anxiety levels before and after the intervention within groups. Additionally, multiple regression analysis will be employed to identify predictors of patient satisfaction and anxiety reduction, with a significance level set at p ≤ 0.05 for all statistical tests.Conclusion: The expected outcome of this study is that virtual reality-based education will significantly reduce pre-procedure anxiety and enhance patient satisfaction compared to standard education. Findings from this research may contribute to improving patient-centered care and developing innovative strategies to optimize emotional preparedness before cardiac catheterization procedures.

The high prevalence of delirium in hospitalized older adults, with significant associated morbidity and mortality, emphasize the need for effective prevention strategies. Limited trials have explored melatonin's potential in preventing delirium among patients admitted to general medical wards. Previous trials on melatonin's preventive role in medical wards had limitations, necessitating a robust, double-blinded, placebo-controlled design with a larger sample size. This randomized, double-blind study of melatonin versus placebo aims to investigate the efficacy of melatonin, a neurohormone regulating the sleep-wake cycle, in preventing delirium among medically hospitalized patients aged 65 or older. Given the high prevalence of delirium in this population and its association with adverse outcomes, the study seeks to contribute valuable insights into an effective preventive strategy.

This clinical trial aims to assess the effectiveness of Transcranial Magnetic Stimulation (TMS) compared to Treatment as Usual (TAU) in adult patients experiencing their first or second episode of unipolar major depressive disorder (MDD). The primary end point is to determine whether TMS leads to higher rate of remission, response and greater reductions in depression severity, and improved functional outcomes compared to standard pharmacological and psychotherapeutic interventions. The trial will also explore the impact of TMS on quality of life and anxiety symptoms. Participants will be randomly assigned to either the TMS or TAU group, and outcomes will be assessed at multiple time points over a 3-year period. The trial will be conducted at Sultan Qaboos University Hospital's Department of Behavioural Medicine in Muscat, Oman, and is expected to contribute important evidence on the role of non-invasive brain stimulation in treating early-stage depression.

The study's primary objective is to evaluate the effectiveness of Tinazidine compared to Zolpidem in enhancing sleep quality, with secondary objectives including the assessment of adverse effects, safety profile, and patient tolerance with each treatment. The trial will be conducted as a double-blind RCT, with participants randomly assigned to receive either Tinazidine (0.1 mg/Kg/HS) or Zolpidem 10 mg HS, for 12 weeks. Eligible participants, aged 18-60 years, diagnosed with primary insomnia as per DSM-5 criteria, will be recruited from an outpatient sleep clinic affiliated with Al-Masara Hospital. Data on sleep quality, and side effects, will be collected using the Sleep Pittsburgh Sleep Quality Index (PSQI), Clinical Global Impression (CGI), sleep diaries, actigraphy, polysomnography, and regular clinical interview though OPD follow-up visits. The primary outcome considered was the mean global PSQI score before and after the treatment. The primary outcome will be measured four times (baseline, 4 weeks, 8 weeks, and 12 weeks), We considered an attrition rate (dropout/lost follow-up) of 10%. Therefore, the sample size is 90 subjects (45 in each group). Group comparisons for mean scores will be conducted using independent samples t-tests, and within-group comparisons will be assessed using paired samples t-tests. Changes in sleep quality over time between treatment groups will be evaluated using repeated measures ANOVA. Associations between categorical variables will be examined using Chi-square tests (including Fisher's exact or Likelihood ratio tests as appropriate). Statistical significance will be considered for p-values less than 0.05. All analyses will be performed using IBM SPSS Statistics (Version 29.0). The findings of this study seek to elucidate the comparative efficacy and safety profiles of Tizanidine and Zolpidem in treating primary insomnia. The study aims to offer insights into the effectiveness of Tizanidine versus Zolpidem in improving sleep quality among patients with primary insomnia. Through the evaluation of efficacy, adverse effects, and safety profiles. This study aims to inform clinicians and healthcare practitioners about the optimal treatment choices for individuals with primary insomnia.

The aim of this study is to evaluate the efficacy of hydroxyzine compared to treatment as usual (TAU) for patients with panic disorder. By conducting a pilot study, we hope to provide initial data on the feasibility and potential impact of hydroxyzine for this population. This will inform the design and power calculations of a larger, more comprehensive study in the future. Objectives: To assess the feasibility of conducting a randomized controlled trial (RCT) of hydroxyzine for panic disorder. To evaluate the effectiveness of hydroxyzine compared to TAU in reducing panic symptoms in patients with panic disorder. To explore the potential side effects and tolerability of hydroxyzine in this population. Methods: This will be a single-center, open-label, randomized pilot study. A total of 30 patients with a primary diagnosis of panic disorder will be recruited from a psychiatric outpatient clinic. Participants will be randomly assigned to receive either hydroxyzine or TAU for 8 weeks. The primary outcome measure will be the change in panic symptoms as assessed by the Panic Disorder Severity Scale (PDSS). Secondary outcome measures will include the Hamilton Anxiety Rating Scale (HAM-A) and the Clinical Global Impression-Severity (CGI-S) scale. Participants will be assessed at baseline, 4 weeks, and 8 weeks. Adverse events will be monitored throughout the study. Expected Results: This pilot study is expected to provide preliminary data on the feasibility and potential efficacy of hydroxyzine for panic disorder. The results will inform the design of a larger RCT to further evaluate the efficacy of hydroxyzine for this population. Significance: There is a need for effective and well-tolerated treatments for panic disorder. If found to be effective, hydroxyzine could provide a new option for patients with this condition, potentially improving their quality of life and functioning.
