There are about 10004 clinical studies being (or have been) conducted in Brazil. 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.
The aim of this study is to assess the cost-effectiveness of the mandibular overdenture retained by a single implant. The study hypothesis is that SIMO is more effective but more costly than the conventional denture, though this incremental cost is relatively low for the offered effectiveness in terms of clinical and patient-reported outcomes.
This study aims to evaluate the acute effects of neonatal hydrokinesiotherapy in reducing stress in newborn preterm infants in the neonatal intensive care unit. Salivary cortisol samples were collected, pain applying the Neonatal Infant Pain Scale Scale (NIPS), heart rate, respiratory rate and oxygen saturation before and after hydrotherapy.
Fluid management of children during neurosurgery is not well established. Hypotonic solutions, commonly still used in pediatric patients, may enhance cerebral edema and worse operative conditions. This study compares two different isotonic solutions administered perioperatively regarding acid base and fluid electrolyte disturbances.
The objectives of Period 1 were the following: - To compare the safety and efficacy of upadacitinib 7.5 mg once daily (QD) monotherapy (for participants in Japan only), 15 mg QD monotherapy, and 30 mg QD monotherapy versus weekly methotrexate monotherapy for the treatment of signs and symptoms of RA in methotrexate-naïve adults with moderately to severely active RA; - To compare the efficacy of upadacitinib 15 mg QD monotherapy and upadacitinib 30 mg QD monotherapy versus weekly methotrexate monotherapy for prevention of structural progression in methotrexate-naïve adults with moderately to severely active RA. The objective of Period 2 is to evaluate the long-term safety, tolerability, and efficacy of upadacitinib 7.5 mg QD (for participants in Japan only), 15 mg QD, and 30 mg QD in adults with RA who have completed Period 1.
The objective of this study is to assess whether supplementation with resistant starch from the rice-flour coffee developed by EMBRAPA, as well as from an already industrialized product (Hi-Maize of Ingredion®) could modulate the intestinal microbiota of patients with CKD ( both patients under conservative treatment, such as dialysis treatment), as well as exerting a beneficial effect with respect to reducing levels of inflammatory markers of oxidative stress, uremic toxins and in addition, markers of cardiovascular disease.
Regional lymph node metastasis is a major determinant of local recurrence and overall survival rates in patients with colorectal cancer. Because of the poor prognosis associated with the presence of lymph node metastasis, stage III colorectal cancer patients should receive adjuvant treatment with chemo and / or radiation therapy according to the site of tumor. Several authors have investigated the use of revealing solutions for lymph node clearance in colorectal cancer. Most studies comparing conventional histopathological specimen examination to any lymph node clearing technique showed that the use of revealing solutions increases the mean number of lymph nodes harvested, usually in a statistically significant manner. It is still controversial the impact of the use of revealing solutions for upstaging of lymph node status and consequently for the indication for adjuvant therapy. Therefore will be conducted a randomized clinical trial to compares the performance of GEWF and Carnoy solutions for the histopathological examination of patients with colorectal cancer. The aim of this study is to determine the lymph node revealing solution with the best performance (increase in the mean number of lymph node harvested and lymph node upstaging) in patients with colorectal cancer.
One of the most effective strategies to decrease radiation exposure during ureteroscopy is to use low dose. However, the quality of the image obtained is inferior to full dose image. The main concern is to maintain the stone free and complication rate despite the inferior quality of image obtained. Our aim was to evaluate if reducing the dose of fluoroscopy to ¼ instead of full dose would impact in a reduction of total radiation exposure despite a possible increase in fluoroscopy time. Also, if this strategy would impact in operation time, stone free rate and complication rate of unilateral semi-rigid ureteroscopy for ureteral stone treatment due too less than optimal fluoroscopy image. All patients over 18 years old diagnosed with ureteral stone from 5 mm to 20 mm in diameter by CT scan were counseled regarding their treatment options. Patients who failed spontaneous passage or medical treatment or chose endourologic treatment were included in this study. Patients with abnormal urinary anatomy such as horseshoe kidney, pelvic kidney or duplex system were excluded from the study.
Migraine is a common medical condition. Several studies suggest that obesity and/or weight gain are risk factors for aggravating migraine course, especially increase the frequency of headache episodes. The aim of the current study was to evaluate whether nutritional intervention would be able to improve clinical parameters (as assessed by MIDAS and HIT) of patients with migraine.
The main purpose of this study is to determine new diagnostic criteria for an eye disease called keratoconus.
The purpose of this study was to confirm efficacy and safety of osilodrostat for the treatment of patients with Cushing's disease who are candidates for medical therapy.
