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.
The study aims to identify metabolites present in intervertebral discs colonized by C. acnes from patients with low back pain and degenerative disc disease, correlating them with their clinical, radiological and demographic profiles.
This parallel-group randomized, controlled, clinical trial aims to investigate the influence of a 6-month home-based, remotely-monitored, exercise training intervention on musculoskeletal health in patients with Systemic Lupus Erythematosus who have undergone glucocorticoid pulse therapy.
Pacients who use mechanical ventilation (MV) need to pass weaning, a interruption process of ventilatory support. To predict this outcome, several scores have been developed, however, fail index in weaning and extubation remains high. The objective of this study is to evaluate the effect of ExPreS - Extubation Predictive Score - on rates of successful extubation. By a randomized clinical trial, this reseach will take place in ICUs of several hospitals. Therefore, it is expected that a difference between devices to predict extubation sucess exists and, because ExPreS is a protocol that evaluates different parameters related to many organs and systems, it presents a better capacity of predicting extubation sucess in MV patients.
Abstract: Antineoplastic therapy (AT) is one of the most used treatment modalities to fight cancer, either curatively or palliatively. There are several possible routes of administration, but the intravenous is the most used for its safe absorption and maintenance of the drug's serum level (1). Among the central catheters used in oncology, the long-term Totally Implantable (CTI) catheter is one of the most well accepted by patients and healthcare professionals. Being used in the administration of fluids, medication, parenteral nutrition or to obtain blood. Maintaining the CTI is essential to maintain its permeability, and thus, its proper functioning (2-4). The COVID-19 pandemic requires several readjustments from health institutions to ensure healthy environments for patients and less exposure to the hospital environment, one of the measures to focus on increasing the maintenance time of the ICU from 30 to 60 days. Objective: To verify the safety of increasing the maintenance interval of the Port-a-Cath catheter from 30 to 60 days through the rate of infection, obstruction, dysfunction in the infusion of solutions and blood reflux at the end of a year of follow-up. Method: This is an observational study, a single research arm, with a scheduled duration from January 2021 to August 2022 at the chemotherapy clinics of the A.C.Camargo Cancer Center. Expected results: This investigation is expected to demonstrate that maintenance with saline every 60 days does not increase obstruction or infection in patients who are in clinical follow-up compared to maintenance for 30 days.
Standard therapy for localized rectal cancer includes chemotherapy and radiation therapy, followed by a "recovery" period of 7-12 weeks, surgery and adjuvant chemotherapy for 3-6 months. Even though this protocol achieves high cure rates, many patients need a rectal amputation with placement of definitive colostomies. About 10-20% of patients have a complete clinical response to chemo-radiation and no tumor can be found in the surgical specimen. These patients can be followed with close surveillance and avid surgery. The aim of this study is to evaluate if a strategy including the use of a highly active chemotherapy called "FOLFIRINOX" during the 12 weeks between the end of radiation therapy and evaluation for surgery increases the rates of complete response and, therefore, allows more patients to undergo non-surgical management.
A clinical, multicenter, randomized, parallel-group, double-blind, double-dummy, comparative study of non-inferiority. ⚠️Study will only be conducted in research centers in Brazil (please do not send e-mail if your center is outside brazil) .
Endophthalmitis is a severe inflammatory eye condition with profound impairment of vision, which can lead to irreversible visual loss and requires immediate treatment. There is no way to completely prevent endophthalmitis, however, through prophylactic methods, it is possible to reduce its incidence. Currently, the only technique that has reached category II of evidence in reducing the risks of endophthalmitis is the use of 5% povidone-iodine eye drops, moments before surgery. In 2007, the European Society of Cataract and Refractive Surgery (ESCRS) released a large multicenter randomized clinical trial, with data on the reduction in the rates of endophthalmitis, using the intracameral antibiotic therapy technique of perioperative cefuroxime. However, much is discussed about the risks related to the technique, such as dilutional errors, contamination, anaphylaxis and cost-effectiveness, which still makes the conduct debatable. The study evaluates the use of intracameral Moxifloxacin 0.5% (Vigamox®) as prophylaxis in cases of endophthalmitis after open ocular trauma;
Acute pain is one of the complications after cardiothoracic surgeries . It can delay patients´recovery and may increase patients´morbity and mortality. This study intends to evaluate Dexmedetomidine, a highly selective α- 2 receptor agonist, that is currently applied safely and efficiently in intraoperative cardiac surgery. It has analgesic, sedative, anxiolytic and sympatholytic properties, without respiratory- depressant effect. The aim of this study is to investigate whether the intraoperative use of dexmedetomidine is better than the standard analgesia used in the intraoperative period to reduce pain and the consequences of it.
Cervical cancer remains the first or second leading cause of cancer death among women in many low-and middle-income countries. Cervical cancer prevention programs in low-resource settings are hampered by a lack of personnel with appropriate clinical expertise, lack of pathology services, and lack of associated infrastructure. There is an urgent need for appropriate diagnostic tools to enable accurate screening and diagnosis in low-resource settings. The purpose of this study is to develop and validate a low-cost Multimodal Mobile Colposcope (MMC) for global cervical cancer prevention programs. This new device will combine the imaging capabilities of a mobile colposcope with the microscopic imaging capabilities of a fiber-optic confocal imaging probe.
INTRODUCTION: Coronavirus 2019 disease (COVID-19), caused by the Severe Acute Respiratory Syndrome (SRAG) of coronavirus 2 (SARS-CoV-2) surpassed the global number of 119,603,761 cases, with more than 2,649,722 reported deaths . There is sufficient evidence for a possible post-covid-19 syndrome, designating sequelae with persistent symptoms. Respiratory muscle training improves respiratory muscle strength, exercise capacity, diaphragm muscle thickness, and dyspnea in various patient populations, especially in those with the greatest reduction in basal respiratory muscle strength. OBJECTIVE: To evaluate the effectiveness of a home inspiratory muscle training protocol in improving respiratory muscle strength, dyspnea and quality of life in post-Covid-19 patients. MATERIALS AND METHODS: This is a clinical, controlled, randomized and blind trial, which will be carried out at the Institute of Tropical Medicine of the Federal University of Rio Grande do Norte. The sample size will be performed using GPower software version 3.1.9.2 (Kiel, Germany) for Windows and will be established after conducting a pilot study with 5 participants in each group (total of 10 subjects) for a hypothetical two-way ANOVA test, using the main variable the Maximum Inspiratory Pressure (PImax.). The subjects included in the research will undergo three evaluation moments: Pre-training (Initial), Post-training (6 weeks) and Retention Test (24 weeks) for clinical evaluation form, anthropometric measures, respiratory muscle strength, volumes and capacities pulmonary symptoms, dyspnea, perceived exertion and fatigue, handgrip strength, six-minute walk test, anxiety and depression, post-covid functional status. After the initial assessment, all volunteers will receive a POWERbreathe® device (POWERbreathe®, HaB Ltd, Southam, UK) to carry out the training. EXPECTED RESULTS: provide a safe, effective and easy-to-perform treatment for post-covid-19 patients.
