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 detect similarities and differences in the endometrium of fertile and infertile patients
The aim of this study is to evaluate the effects of an exercise program with a cycle ergometer in functional outcome and related-health quality of life (RHQL) in elderly patients with total hip arthroplasty.
Cardiovascular diseases (CVD) prevail as the main cause of death in developed and developing countries and are among the most frequent causes of disabilities in Brazil and in the world. Economic alternatives have been studied to assist in reducing cardiovascular risk factors. Within this context, the Solanum menogena, whose fruit known as eggplant is widely consumed in Brazil, is being used in alternative medicine with the purpose to reduce the concentrations of cholesterol, glucose and promote loss of body weight. Aubergine (eggplant) stands out for its high fibre content (approximately 40%) and low fat content. In addition, it is popularly known for its functional properties, aiding in reducing the risk of coronary diseases. The purplish coloring of the eggplant peel is attributed to the large amount of flavonoids, which have antioxidant properties and contribute to the flavor of eggplant. The investigators hypothesis is that the eggplant flour associated with a restricted calorie diet has effect in reduction in waist circumference, reduction of body fat and increasing HDL-cholesterol; this way, contributing to the reduction of cardiovascular risk factors All participants will be informed about the research and they will have to sign a consent form. The volunteers will be divided into two groups: one group will receive a restricted-calorie diet and supplementation with eggplant flour; and the other will receive a diet plus a placebo for 120 days, being both groups evaluated monthly. In each consultation, evaluation of weight, body composition, fulfillment of the diet and blood pressure measurement will be performed. In addition, blood will also be collected in order to determine glucose, insulin, total cholesterol, LDL, HDL, triglycerides, oxidized anti-LDL antibodies, 15-isoprostane and minerals (selenium, zinc, iron, manganese, magnesium and copper). The results will be analyzed by statistical program. The investigators expect that with the results obtained, the eggplant flour can be used as an ally in the prevention of cardiovascular diseases.
Effectiveness of lutein, zeaxanthin and trypan blue to stain the anterior lens capsule during cataract phacoemulsification.
The purpose of this study is to determine the glycemic efficacy and safety of dulaglutide compared to insulin glargine in the treatment of participants with type 2 diabetes and moderate or severe chronic kidney disease.
The purpose of this study is to evaluate the clinical efficacy of indapamide 1.5mg / losartan 50mg and indapamide 1.5mg / losartan 100mg on reduction of blood pressure.
There are no studies exploring the benefits of a diet composed of typical Brazilian food in the secondary prevention of cardiovascular diseases. Randomized studies show that the Mediterranean diet is beneficial for patients with established cardiovascular disease or in risk for CVD development. Indeed, nutritional composition of the Mediterranean Diet is one of main references for dietary guidelines for treatment and prevention of CVD in Brazil and the world. However, in many countries, such as Brazil, most foods of the Mediterranean diet are not widely available, may be expensive or are not part of population eating habits. So, the prescription of the Mediterranean diet intervention for cardiovascular disease to the Brazilian population may not be feasible, leading to a low adherence. In this context, patients with established CVD have a low compliance to nutritional prescription. The BALANCE Program, considers 3 concepts: a) A dietary prescription guided by nutritional content recommendations from the Brazilian national guidelines; b) A nutritional education program based on fun, playful strategies and suggestions of affordable foods; and c) Intensive follow-up through one-on-one visits, group sessions, and phone calls. This is the first proposal to use these concepts concurrently with the objective to increase adherence of secondary prevention patients to the diet proposed by the guidelines. Therefore, The primary outcome is a composite of death (any cause), cardiac arrest, acute myocardial infarction, stroke, myocardial revascularization, amputation for peripheral arterial disease, or hospitalization for unstable angina.
The objective of this study was to evaluate the advanced maternal age as a rationale for performing intracytoplasmic morphologically selected sperm injection (IMSI). This prospective randomized study included couples undergoing intracytoplasmic sperm injection (ICSI) as a result of advanced maternal age (≥ 37 years old). Couples were randomly allocated to receive one of two sperm selection procedures (ICSI, n = 33; or IMSI, n = 33). The groups were compared with regard to fertilization rate, percentage of high-quality embryos, implantation, pregnancy and miscarriage rates.
There are no available medical treatment options for patients with non-functioning pituitary adenomas (NFPA) or with resistant prolactinomas to dopamine agonists (DA) who are not cured by surgery. The study of the receptors by quantitative mRNA expression levels and immunohistochemistry analysis might end with a better understanding of these tumors. Besides that, it will be assessed the in vitro and in vivo responses to pasireotide (for NFPA and prolactinomas) and cabergoline (for NFPA). These responses will be compared with the receptor expressions which may be a tool as a predicting element of the response to these compounds.
The purpose of this study is the randomized blind research of the assessment of the different levels of glycemia during Coronary Artery Bypass Graft (CABG) with cardiopulmonary by-pass (CPB) between clonidine and placebo. As clonidine decrease the inflammatory response during cardiac surgery, the investigators would like to know if the glycemia levels in clondine group will be lower than placebo group.
