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.
Despite the development of new drugs, nausea and vomiting after surgery (PONV) are still frequent. Antagonists 5HT3 receptors, such as ondansetron and palanosetron, are among the main characterized prophylactic agents in patients at high risk, however there are few studies comparing the efficacy of these drugs and no study that addresses women aged over 60 years. In this prospective, randomized, double-blind study, 80 women nonsmokers, undergoing laparoscopic cholecystectomy will be divided into two groups, receiving during anesthetic induction intravenous ondansetron 4 mg (n = 40) or palonosetron 75 mcg (n = 40) prophylaxis of PONV.
The primary objective of this study was to demonstrate whether, in addition to standard of care, finerenone is superior to placebo in delaying the progression of kidney disease, as measured by the composite endpoint of time to first occurrence of kidney failure, a sustained decrease of estimated glomerular filtration rate (eGFR) ≥40% from baseline over at least 4 weeks, or renal death.
1. OBJECTIVE: To determine the efficacy and safety of a single-incision mini-sling compared with a transobturator midurethral sling for stress urinary incontinence (SUI) treatment. 2. METHODS: This prospective single-center randomized controlled trial will involve 100 women with a diagnosis of SUI. Primary outcomes were the objective and subjective cure rates, defined as negative cough stress and pad tests, and satisfaction rates. Quality of life assessed by the Incontinence Quality of Life Questionnaire and the Urogenital Distress Inventory Short Form, operation time, complications, and reoperation rates were also recorded. The efficacy was analyzed using a noninferiority test with a margin of 15%. For the noninferiority test, a P value >.05 rejects the noninferiority hypothesis of the mini-sling.
Objectives: To identify factors associated with disease recurrence in patients with high-grade cervical intra-epithelial neoplasia (CIN) undergoing large loop excision of the transformation zone (LLETZ). Study Design: A case-control study that included 103 patients. Patients were included in the study if they had a history of surgery for conization by LLETZ for the histopathological diagnosis of cervical intraepithelial neoplasia grades II and III (CIN II and CIN III). Follow-up exams were conducted every six months with Pap smear collection and colposcopic examination with biopsy, when necessary, for a minimum period of twelve months. Cure was defined as a normal follow-up examination within 24 months. During follow-up, relapse occurred when cytology and/or biopsy results showed that CIN had returned after 12 months, at which time a new cervical conization by LLETZ was performed.
Stroke is a neurovascular event characterized by impaired blood supply to the brain due to rupture or obstruction of certain cerebral arteries, which often results in hemiparesis and can affect individuals of any age and sex, being prevalent in the elderly population. Among the main treatments available for stroke rehabilitation, most of them demands an appropriate structure and high-qualified personnel. Searching for more affordable treatment options, several studies suggest the use of mental practice with motor imagery as a potential therapeutic tool, since it can be performed at any place or any time the patient wishes, including their own homes. Motor imagery can be defined as the covert cognitive process of imagining a movement of your own body(-part) without actually moving that body(-part). Within this context, the objective of this study is to investigate the effects of mental practice for mobility, gait function and speed and muscle strength of the lower limb in subacute post-stroke hemiparesis.
The FANTOM II trial is intended to assess safety and performance of the Fantom Bioresorbable Coronary Scaffold in native coronary arteries.
Patients will be treated in accordance with the standard medical practice of the hospital where they have been recruited during their participation in this study. No additional assessments or tests will be required. SAGIT® is a new instrument developed by a group of acromegaly experts to help practicing endocrinologists to manage acromegalic patients and disease activity in their clinical practice and define acromegaly staging. It reports 5 elements: Signs and symptoms - S; Associated comorbidities - A; Growth hormone (GH) concentration - G; Insulin-like growth factor 1(IGF-1) concentration -I; Tumour size- T. The instrument has been pre evaluated during a qualitative pilot study. The purpose of the validation study is to define and validate the scoring of the SAGIT® instrument.
The aim of this study is to investigate weather the breathing exercises of Yoga are effective in altering clinical impact, anxiety, depression and quality of life in Chronic Obstructive Pulmonary Disease patients.
In this study, all patients must have already completed first-line chemotherapy to treat extensive-stage disease small cell lung cancer. The purpose of this study is to show that nivolumab, or nivolumab plus ipilimumab followed by nivolumab by itself, will prolong overall survival when administered as consolidation treatment in patients that are stable or responding after chemotherapy. Patients receiving treatment will be compared with patients taking placebo.
Cerebrovascular disease is a leading cause of death and the leading cause of serious long-term disability. Carotid artery stenting (CAS) and carotid endarterectomy (CEA) are alternative strategies for stroke prevention in patients with atherosclerotic carotid disease.The safety and efficacy of CAS compared to CEA still remains questioned, and CEA has been considered to the first-line treatment of carotid stenosis in worldwide. The purpose of this study is to compare the practice and outcomes of CAS and CEA in a real world setting at Public University Hospitals in Brazil.
