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.
To evaluate the recurrence and postoperative complications rates after conjunctival autograft surgery using fibrin adhesive for primary pterygium
This randomised, open label phase III trial will be performed in patients with adenocarcinoma of the lung with tumours harbouring an Epidermal Growth Factor Receptor activating mutation. The objectives of the trial are to compare the efficacy of single agent BIBW 2992, Arm A, with Pemetrexed/Cisplatin chemotherapy, Arm B, as first line treatment for this group of patients.
This open-label randomized 2arm study will determine the emergence of viral resistance in patients with seasonal influenza A infection treated with Tamiflu. Eligible patients </=5 years of age will be randomized to receive Tamiflu at either standard dose (30-75mg orally bid) or double dose (60-150mg orally bid) for 5 days. Target sample size is >100.
The purpose of this study is to identify the predisposing factors, epidemiological features and clinical and microbiological diagnosis of infectious keratitis in two public referral centers of ophthalmology in a countryside city of Brazil.
Primary Objective: To demonstrate the superiority of insulin glargine over insulin NPH (Neutral Protamin Hagedornon) the change in HbA1c from baseline to the end of the treatment period. Secondary Objective: To compare between treatment groups: - Plasma glucose (fasting, nocturnal) over time, - Changes from baseline in HbA1c over time, - Percentage of patients who reach the target of HbA1c <7 and <6.5, - Use of prandial insulin as rescue medication at month 6, - Incidence and rate of hypoglycemia (symptomatic diurnal and nocturnal, asymptomatic and severe), - Daily dose of insulin, - Change in body weight from baseline, - Evolution of 8-point plasma-glucose (PG) profiles, - Overall safety, - Patient reported outcomes (treatment satisfaction).
The stretching is performed within sports to improve muscle performance and prevent muscle injury. However, recent studies are contradictory with common practice. Then raised the possibility that stretching before physical activity performed can decrease the muscle performance of healthy subjects.
Metabolic syndrome, a group of cardiovascular risk factors related to insulin resistance, is a major determinant of cardiovascular mortality. Intermittent claudication is a symptom of an early stage of atherosclerosis. The aim of this study is to determine the prevalence of the metabolic syndrome in patients with intermittent claudication and its correlation with age, gender, localization of arterial obstruction and association with coronary artery disease.
The ozone therapy has been coming up as a new therapeutic modality. Medicine has been practicing since XIX century and counted great results. It is indicated for the treatment of 260 different pathologies. The researches in Dentistry has showed promising results, indicating a wide spread action in whole dental specialties. The great oxidative power of ozone provides a great antimicrobial effect and it increases the adenosine triphosphate (ATP) synthesis that can be considered as a general improvement of the cell metabolism, which can potentize the repair process. Thus, these facts justify the present study which will assess the increase of speed of apical periodontite repair.
Obese patients with metabolic syndrome without diabetes or ischemic heart disease were randomized to three lifestyle interventions: 1. hypocaloric tailored diet with standard recommendations 2. pragmatic healthy style diet adapted to brazilian habits with portion control and pedometers to perform 10000 steps daily recorded or 3. pragmatic healthy style diet adapted to brazilian habits with portion control plus fitness three times a week under direct supervision. The main outcome was brachial reactivity, a surrogate marker of atherosclerosis, and secondary outcomes were cardiometabolic profile, arterial pressure and anthropometric measures: weight,waist circumference and bioimpedanciometry to access fat proportion and insulin sensitivity.
The surgery stress relives systemic inflammatory response by hormones and adrenergic receptors. When the pro-inflammatory mediator is higher than anti-inflammatory response, the physiologic status is impaired and the patient is more susceptible an infection and cardiovascular collapse. The anesthesia can abolish or minimize the surgery stress, improved more safety to the patient. This study is a double blind controlled trial with 40 patients divided in two groups (EMLA and Dorsal Penile Nerve Block - DPNB) submitted a standard inhalator anesthesia and postectomy surgery by Plastbell®. The investigators will be observe heart rate, respiratory rate, arterial pressure, involuntary movements during the surgery and pain in the pos-operatory. With this study, the investigators can define what tactic (EMLA or DPNB) associated a general anesthesia is more effective to relive the pain when children are submitted a postectomy by Plastbell®.
