There are about 864 clinical studies being (or have been) conducted in Iran, Islamic Republic of. 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 is a randomized, single blind, multi-center, phase two clinical trial. Inclusion criteria are consist of non-metastatic esophageal cancer who are going to receive chemo-radiotherapy. Sample size is 100 people (50 people in each group). In the intervention group, patients are going to inject an enoxaparin (40 mg) daily concurrent by chemo-radiation. Therefore patients with esophageal cancer are going to assign randomly to control group (only chemo-radiotherapy) and intervention group (chemo-radiotherapy+enoxaparin) using 1:1 allocation. Four to 6 weeks after treatment, all patients undergo upper GI endoscopy and then esophagectomy. Endoscopic and pathological findings (after esophagectomy) are considered as clinical and pathological response, respectively.
Vitamin D supplementation not only has beneficial effects on morbidity and mortality in critically ill patients but it may also lead to alleviate of seizure, brain edema, infection, pain and some other perioperative complications, possibly in part through an attenuation of the immune response.In this trial patients with brain tumor under craniotomy will receive a single high dose vitamin D compared to control group.
The aim of this study is to compare results of endoscopy assisted nasolacrimal probing with the standard simple probing in cases with congenital nasolacrimal duct obstruction . Furthermore, we will identify associated anatomical anomalies. We believe results of this study can be valuable in better understanding of this disease and provide a high evidence level necessary to propose a classification and management algorithm. Children with symptoms of unilateral or bilateral congenital nasolacrimal duct obstruction, no past surgical management, with one or more of the below criteria will be included: 1. Non-resolving symptoms of epiphora and/or discharge. 2. Congenital dacryocele not resolved after 1 week of lacrimal sac massage, and topical antibiotics. 3. As soon as subsidence of acute dacryocystitis. Parents will be asked about symptoms and patients will undergo lacrimal tests before and after operation in one week, one month and 3months based on a special record form. Patients will be randomly assigned to "simple probing" group or "endoscopy assisted probing" group. All operations will be performed in operative theater and under general anesthesia. Pre- and post-operative examinations will be performed in plastic clinic in Farabi hospital.
This is a prospective, randomised double blind, controlled, parallel-group phase I and II study. Its aim is to assess the Evaluation of the intramyocardial injection of autologous bone marrow derived mononuclear stem cells is safe and effective in hear failure patients with reduced left ventricular ejection fraction(<=30%) when compared to a control group of patients undergoing best medical care.
To examine the impact of health determinants at the individual (e.g. health related behaviors) and societal level (e.g. environmental factors, health related policy, quality of health systems) on health outcomes (e.g. death, non-communicable disease development) across a range of socioeconomic and health resource settings. Additional components of this study will examine genetic factors for non-communicable diseases. This will be examined both through a cross sectional component, and prospectively (cohort component).
The fixed-dose combination of sofosbuvir and daclatasvir in a single pill is being used for the treatment of hepatitis C in Iran. In this study the efficacy of this combination is evaluated in 1000 patient with hepatitis C.
General objective: To assess the effect of vitamin D supplementation on metabolic syndrome among older adults in Karaj city, Alborz province in Iran. A two-arm randomised controlled trial (RCT) will be conducted by recruiting participants. Inclusion Criteria: Food insecure, metabolic syndrome; Vitamin D deficiency Exclusion Criteria: those who are already taking any type of vitamin D supplements, Individuals with a history of allergy, Those subjects with serious medical condition such as cancer, heart attack, stroke, and etc., Intervention group: The intervention will start from 10 of May 2017 to 11 of July 2017 for 2 months. The intervention group will receive 50,000 U vitamin D3 per week (equivalent to 1,250 μg) for 8 weeks plus pamphlets and brochures about nutrition and health at the beginning of the study. Control group: The respondents in control group will receive placebo plus brochures and pamphlets related to nutrition and health at the beginning of the study. The data collection process will identify the older adults for both groups; intervention and control. Consent will be obtained from those who are eligible. Anthropometric measurement (height, weight, body mass index, and waist circumference), blood pressure measurement, blood taking and three-day food record will be obtained during baseline from all study respondents in the intervention and control groups. Primary Output: Achieving 25 (OH) D upper than insufficient serum 25(OH) D level >30 ng/l. Secondary Output: Reduction anthropometry (body mass index (BMI) and waist circumference (WC), Improved Biomarkers indicators (lipid profile, fasting blood fast), improved blood pressure before and after intervention.
Adequate growth of the endometrium is crucial for implantation. Accordingly, the pregnancy success rate of patients with a thin endometrium is low. Furthermore, there is a little information about the factors responsible for impaired endometrial growth in patients with a thin endometrium. The researches have revealed that nitric oxide (NO) release can cause relaxation of vascular smooth muscle through a cyclic guanyl monophosphate (cGMP)-mediated pathway. Sildenafil is a type 5-specific Phosphodiesterase inhibitor that augments the vasodilatory effects of NO on vascular smooth muscle by preventing the degradation of cGMP and could improve blood flow and endometrial thickness. This study is designed to evaluate the effect of vaginally administered sildenafil suppositories on IVF/ICSI outcome of infertile patients with repeated IVF/ICSI failures.
The purpose of this international, multicenter service review is to describe and compare ventilation management in patients at risk of acute respiratory distress syndrome (ARDS) versus patients not at risk and patients with established ARDS, and to ascertain whether certain ventilator settings and ventilation parameters are associated with pulmonary complications or development of ARDS after start of ventilation in patients in intensive care units (ICUs) in Asian countries. Participating centers will include adult patients undergoing mechanical ventilation in the ICU during a 28-day period. Patients' data will be collected during the first 7 days in the ICU, or until ICU discharge. Follow up is until ICU discharge. The primary outcome includes two main ventilator settings, i.e., tidal volume and the level of positive end-expiratory pressure. Secondary endpoints are development of ARDS in patients without ARDS at the onset of mechanical ventilation, worsening of ARDS in patients with ARDS at the onset of mechanical ventilation, pulmonary infection, other pulmonary complications, need for tracheostomy, duration of ventilation, length of ICU stay and ICU mortality.
The effects of colostrum on intestinal permeability in critical ill patients has not been investigated. In current trial, intensive care unit patients with enteral feeding will receive either enteral colostrum or maltodextrin as placebo.
