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.
This clinical trial studies conservative surgery in treating patients with low-risk stage IA2 or IB1 cervical cancer. Conservative surgery is a less invasive type of surgery for early stage cervical cancer and may have fewer side effects and improve recovery.
There is no AED or medication that has been demonstrated to affect the development of post-traumatic epilepsy. Biperiden is a cholinergic antagonist, acting in the muscarinic receptor, that is widely used as an anti Parkinson drug. The investigators data with animal models of epilepsy indicate that anti-muscarinic agents might affect the natural course of the disease in the case of post-traumatic epilepsy.
Septic shock is a frequent reason for admission on pediatric intensive care units. Interventions which can change morbidity and mortality of septic shock patients are of great interest. Steroid replacement in adults with severe sepsis and septic shock have been extensively studied. It was recently demonstrated that low dose steroid (< 300mg/ day) used for more than 5 days was associated with decreased mortality and lower requirement of vasoactive support in the adult population that had a low response to the ACTH test. However, this was not confirmed in the latest results from the CORTICUS study. Use of low dose hydrocortisone, or any other steroid has not been studied in critically ill children. Mortality associated with sepsis in children has decreased in the last decade and currently it is close to 10%, making it difficult to power a study able to show reduced mortality. Taking into account the results from previous studies reporting the high incidence of adrenal failure and its association to worse outcome, we have designed a clinical trial to evaluate the effect of low dose hydrocortisone in children with septic shock: Cortisol Replacement in Children with Sepsis Study.
Sixty percent of patients with difficult to control asthma seen in our outpatient clinic are obese. The impact of weight reduction in this subpopulation of asthmatics has not been studied. Our aim is to evaluate the impact of weight reduction on asthma control of these patients.
Rolandic Epilepsy is the most common form of childhood epilepsy. It is classified as idiopathic, age-related epilepsy syndrome with benign evolution. The absence of neuropsychological impairment is part of the criteria of benignity of this epilepsy syndrome. However recently have been suggested several deficits related to attention and language. The purpose of this study was assess school performance and to investigate problems of praxis in patients with rolandic epilepsy as compared to a control group composed of normal children with age, gender and educational level equivalents.
The main objective is to evaluate the effect on BMI of a school-based program that discourages the consumption of all sweetened beverages, encourages the reduction in sugar intake, and encourages the increase in physical activity among adolescents and their families from a low socioeconomic area.
The investigators hypothesize that Guaraná, a native plant from the Amazon, might improve chemotherapy-induced fatigue in breast cancer patients undergoing treatment. In order to assess this, the investigators randomized patients to either guaraná extract or to placebo, switching the assigned treatment mid-term through the cycles of Chemotherapy.
The purpose of this study was to analyze the knowledge and attitude about HPV vaccines among Brazilian women after an educative intervention. The knowledge was measured on sexual behavior and HPV infection. The attitude was measured on acceptance of vaccines.
Human papillomavirus (HPV) is one of the most prevalent infections in the world with several millions of new cases diagnosed yearly. Oral HPV infection may be associated with different diseases of oral cavities including some cases of oropharyngeal cancer. The aim of this report is to detect the presence of HPV DNA in samples of biopsies, oral swabs, saliva and serum of patient with oral squamous cell carcinoma (OSCC) and controls. We hoped to find there is correlation among the presence of HPV DNA in the several biological materials and if it is possible to use the saliva as screening to HPV DNA detection. The presence of tumor HPV DNA in blood may be of diagnostic and prognostic value.
This multi-center, randomized, double-blind, active controlled, parallel-group study in type 2 diabetes patients with moderate renal impairment will evaluate the effect on renal function and the safety and tolerability of aleglitazar compared with pioglitazone. Patients will be randomized to receive either 150 mcg aleglitazar or 45 mg pioglitazone as daily oral doses. In addition, a diet and exercise plan will also be implemented during the anticipated time on study treatment of 52 weeks. The target sample size is 200-400 patients.
