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.
Insulin-naive subjects with Type 2 Diabetes Mellitus who are sub-optimally controlled on either maximum tolerated dose of metformin or maximum tolerated dose of metformin plus one or two other oral anti-diabetic medications will have either Prandial Technosphere® Insulin or Technosphere Powder (placebo) added to their oral antidiabetic drugs.
Anesthesia for cesarean section has been a great challenge for the anesthesiologist, for mother and fetus are closely related. So the challenge is to anesthetize the mother without interfering with the physiology of the fetus. The spinal block, although safe, are not free of complications if not treated properly, may be responsible for increased fetal morbidity. Among the major side effects, there is hypotension, with potentially serious consequences for the maternal-fetal dyad. Hypotension in pregnant women at low risk may not lead to major damage, but a pregnant woman with low reserves, as is the case of pregnant women with pre-eclampsia, any drop in blood pressure of the mother can bring harm to the welfare of mother and fetus. Based on the above, the purpose of this study is to compare the effects of maternal and perinatal treatment of hypotension with ephedrine or metaraminol in pregnant women with severe preeclampsia undergoing cesarean section under spinal anesthesia. There will be a randomized, double-blind, which will be included pregnant women with severe preeclampsia with indication of cesarean section, gestational age above 34 weeks gestation and only.Will be Excluded women with hemorrhagic syndromes of pregnancy, HELLP syndrome, eclampsia, cardiovascular or cerebrovascular disease, fetal distress and absolute contraindications to spinal anesthesia. All patients are fully informed of the research objectives and will only be included in the study if they agree to participate and sign the Instrument of Consent. The project was designed following the recommendations of Resolution 196/96 of the National Health and the Declaration of Helsinki for research involving human subjects (2000). In addition, the project was submitted to the Ethics Committee in Research of the Institute of Integrative Medicine Professor Fernando Figueira, is approved. The study will be conducted from June 2011 to July 2012. The study variables are: consumption of metaraminol and ephedrine before and after birth, the occurrence of nausea and vomiting, incidence of maternal hypotension, the occurrence of reactive hypertension, occurrence of bradycardia, pH of umbilical cord, Apgar score 5 minutes, need for face mask ventilation and ICU admission.
The purpose of the study is to determine whether the addition of Ipilimumab to Etoposide and Platinum therapy will extend the lives of patients with Extensive-Stage Disease Small Cell Lung Cancer (ED-SCLC) more than Etoposide and Platinum therapy alone.
This randomized, open-label, multicenter, international phase IIIb study will compare the efficacy and safety of two Herceptin (trastuzumab) dosing regimens in combination with cisplatin/capecitabine chemotherapy in patients with metastatic gastric or gastro-esophageal junction adenocarcinoma. Patients who have not received prior treatment for metastatic disease will be randomized to receive Herceptin intravenously either an 8 mg/kg loading dose followed by 6 mg/kg every 3 weeks or an 8 mg/kg loading dose followed by 10 mg/kg every 3 weeks. Capecitabine will be administered for 6 cycles at a dose of 800 mg/m2 orally twice on Days 1-14 of each 3-week cycle, cisplatin will be administered intravenously for 6 cycles at a dose of 80 mg/m2 on Day 1 of each 3-week cycle. Anticipated time on study treatment is until disease progression occurs.
This is a multi-centre prospective, non-inferiority trial. Patients will be randomized to two treatment groups in a 1:1 ratio and will be stratified by age, Karnofsky Performance Status and extent of the surgical resection. This study will assess the effect of a one-week radiotherapy regimen in comparison with a three-week radiotherapy regimen on the survival of elderly and/or frail patients with glioblastoma multiforme (Frail: ≥>50 years old and with a KPS of 50% or less50%-70%; Elderly and frail: ≥65 years and with a KPS of 50% - 70%; Elderly: ≥65 years and with a KPS of 80% - 100%).
Interferential electrical stimulation (IES) increases local blood flow. It is not known whether increases in blood flow may be caused by inhibition of sympathetic activity, mediated by muscle metaboreflex activity. The purpose of this study was to evaluate the effect of IES on metaboreflex activation in healthy subjects.
The objective of this study is to evaluate the consumption of antimicrobial therapy in patients comparing a rapid molecular test (PCR in Real-Time Multiplex) with blood cultures to identify the etiological agents of sepsis.
Oxaliplatin (Ox) is part of most treatment regimens for colorectal cancer. However, it may induce side effects, such as a specific injury to peripheral nerves called neuropathy. Ox-induced neuropathy is frequently painful. The presence of pain after its administration may hamper the full chemotherapeutic treatment of patients with colorectal cancer receiving this agent. Recently, it has been suggested that the appearance of acute neuropathy after oxaliplatin (Ox) infusion could predict the distal polyneuropathy seen some months after treatment. These two adverse events related to Ox treatment probably share different mechanistic backgrounds. However, recent experimental data suggest that both types of peripheral neuropathies are able to induce central sensitization, a major step to the occurrence of chronic pain. Pregabalin is a molecule used to teat neuropathic pain since it can diminish the peripheral sensitization seen in this painful condition. Recently, it has also been shown that pregabalin can be used to treat neuropathic pain related to Ox treatment. In the present study, we will test the hypothesis that Pregabalin administrated exclusively for three days before and three days after the Ox infusion is able to prevent the occurrence of pain secondary to both the acute and chronic Ox-associated neuropathies. In the classical FLOX chemotherapeutic regimen, Ox is infused in nine sessions during a six-month period. Patients will be followed for a year and nerve conduction tests, quantitative sensory evaluation, pain, quality of life and functional scales will be used to assess the impact of this strategy in the prevention of pain. If this strategy proves to work, this information will have a major impact in the cancer prognosis of patients with colorectal cancer since Ox will be able to administer in its full dose, and will not be limited by neuropathic side effects.
The investigators study aims to determine the effect of prophylactic therapy with Trimethoprim-sulfamethoxazole on the recurrences of toxoplasma retinochoroiditis gondii. This is a randomized, double-masked, in patients with eye condition of acute Toxoplasma gondii retinochoroiditis. Volunteers will be recruited with a previous diagnosis of chorioretinitis presumed Toxoplasma gondii, which show active lesions compatible with recurrence. After the acute phase of treatment of all patients [1 tablet Trimethoprim-sulfamethoxazole (800/160mg) 12/12h during 45 days], the same Stratified by gender) will be randomized in a 1:1 ratio between the group 1 - TMP-SMZ (prophylactic treatment with trimethoprim-sulfamethoxazole 1 tablet every other day for 311 days) or group 2 - placebo (consisting of a placebo pill containing no active ingredient of similar appearance to trimethoprim-sulfamethoxazole, 1 tablet every other day for 311 days). The primary outcomes are incidence of episodes of recurrent chorioretinitis by toxoplasmosis in the follow up of 12, 36, 48, 60, 72, 84, 96, 108, and 120 months. Patients will be followed during the ten years in uveitis clinic at intervals defined as follows: return weekly for 4 weeks, then monthly for 2 months, then each 3 months for 9 months, and finally annually for 10 years.
The purpose of this study is whether an inspiratory muscle training protocol would be associated with an improvement in of the diaphragm mobility, an increase in pulmonary function values , gain strength and endurance of respiratory muscles and improving quality of life.
