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.
Insomnia is defined as some difficulty in sleep onset, consolidation, duration, or quality, despite appropriate opportunities for getting sleep. In the last decade, there is growing evidence associating insomnia and high blood pressure, (HBP), coronary disease, heart failure, atrial fibrillation, as well as with an increased mortality rate. Despite the previously mentioned advances, the real impact of insomnia on HBP is unknown. It is unclear whether the diagnosis and pharmacologic treatment of insomnia will have an impact on 24-h BP. The aim of this study is to outline the prevalence of insomnia in patients with HBP followed in the ambulatories from the Hypertension Units at InCor and Hospital das Clínicas. The main hypothesis is that the prevalence of insomnia is high and most patients remain undiagnosed and consequently untreated. For this phase, up to 1,500 patients with HBP will be selected. Besides the medical records with demographic and anthropometric data, personal and familiar background, as well as regular medication, all patients will perform three systematic and standardized blood pressure checks on electric monitors.
The purpose of this study is to evaluate safety, tolerability and efficacy of BZ371B in intubated patients with severe Acute Respiratory Distress Syndrome.
This is a multicenter, double-blind, randomized, placebo-controlled study to evaluate the safety and efficacy of oral difelikefalin administered as a 1 mg tablet once daily compared to placebo in reducing the intensity of itch in advanced chronic kidney disease (CKD) patients with moderate-to-severe pruritus. This study is comprised of an Efficacy Assessment Phase and a Long-term Extension Phase. The Efficacy Assessment Phase includes a double-blind 12-week Treatment Period (Treatment Period 1), and the Long-term Extension Phase includes a double-blind Treatment Period (Treatment Period 2) of up to 52 weeks.
The purpose is to provide treatment with secukinumab delivered subcutaneously (s.c.) via pre-filled syringe (PFS) for participants who complete study treatment until the Week 104 of the core study CAIN457Q12301 and to obtain long term efficacy, safety and tolerability data
Antimicrobial resistance is a major global problem, particularly in hospital-acquired infections (HAIs). Gram-negative bacilli (GNB), including Enterobacterales, Pseudomonas aeruginosa, and Acinetobacter baumannii, are among the most common pathogens associated with multidrug resistance and HAIs. These bacteria are of special concern because few therapeutic options are available. Traditionally, the duration of treatment for severe multidrug-resistant (MDR)-GNB infections is 14 days. Studies of severe infections by GNB, regardless of susceptibility profile, have shown that shorter antimicrobial treatments are not inferior to traditional durations of therapy and are associated with a lower incidence of adverse effects. However, there are currently no studies assessing whether shorter duration of antimicrobial treatment is effective for MDR-GNB. This open-label, randomized clinical trial aims to assess the non-inferiority of 7-day antibiotic therapy compared to conventional 14-day treatment in severe infections by MDR-GNB.
A great interest exists regarding substances with an immunomodulatory effect for sepsis patients. Recent data have shown that intravenous vitamin C, together with corticosteroids and thiamine, could prevent progressive organ dysfunction and reduce vasopressor use in patients with severe sepsis and septic shock. Its effect on mortality, on the other hand, is yet to be demonstrated. The Vitamins study aims to conclusively determine, through its prospective, multicentre and double-blinded design including 1090 patients, wether Vitamin C, Thiamine and Hydrocortisone in combination can reduce mortality in patients with septic shock.
Gallium-68-prostate-specific membrane antigen (68Ga-PSMA) positron emission tomography (PET) has been increasingly used in the management of PCa in Brazil. Thus, the detection of metastatic lesions is improved over traditional methods e.g. MRI and the diagnosis of mCSPC patients has been proportionally increasing. Due to a lack of guidelines and clinical trials including 68Ga-PSMA-PET imaging, the management of these patients is extrapolated from data based on conventional imaging. Treatment decision and duration of treatment for mCSPC patients based on 68Ga-PSMA-PET imaging is currently unknown. 68Ga-PSMA-PET allows a diagnosis of a different set of low volume oligo-metastatic prostate cancer patients. Based on that, a new gap has been built up, since there are no standards of how those patients are managed and how they respond to conventional therapies, to metastasis direct therapy or even if they could be spared of any treatment, reducing costs and toxicities. This patient population has not been included in clinical trials and its critical to generate information on the diagnosis, treatment and outcome of these patients in clinical practice.
Spinal cord stimulation (SCS) for Parkinson´s disease (PD) has been studied for a decade but consensus on efficacy is still lacking, with the previous stimulation standard paresthesia inducing threshold hampering adequate subject blinding. Considering that tonic stimulation for pain has been shown to be efficacious for most patients on subthreshold stimulation parameters we hypothesize a similar result with it´s use on PD. The investigators aim to: 1. Produce stronger evidence on SCS efficacy for PD in regards to gait, motor scores and quality of life measures by incorporating subthreshold in a randomized cross over placebo-controlled study with a large sample. 2. Identify predictors of good response to SCS therapy by performing trans spinal magnetic stimulation (TSMS) before SCS implant and correlating the response to SCS to that of the noninvasive TSMS. 3. Better provide biomarkers of SCS therapy through functional magnetic resonance imaging and electroencephalographic mapping.
Cognitive Behavioral Therapy (CBT) is used for a group of techniques in which there is a combination of a cognitive approach and a set of behavioral procedures. The basic principle of CBT can be described as follows: emotional and behavioral responses, as well as motivation, are not directly influenced by situations, but by the way in which these situations are usually processed. The worker is any person who has a work activity, regardless of being inserted in the formal or informal market. And, nightshift work, due to its wide application and demand, for technical, social and economic reasons is a topic of great relevance today. However, it can lead to health risks, both in biological and psychological functioning, among other emotional problems, causing greater propensity to stress, anxiety crisis and emotional tiredness. In the food and nutrition units, where the organization of work is strongly guided by Taylorist-Fordist principles, structured based on routines, technical standards and organization charts for the meals production, giving attention and dedication to the behaviors and habits of employees, become some strategies for maintaining and improving motivation for work and quality of life in this environment. Objective: to evaluate the effects of an intervention to change eating behavior on the perception of quality of life and eating habits of night workers in food and nutrition units. Method: This is a research project, involving a systematic review (study I) and a clinical trial (study II). The systematic review aim to investigate whether there is a difference in eating behavior between workers, the one that works during the day and the other at night. The second study will consist of two groups; one control and one intervention. The research will consist on a web-based strategies, with two evaluative moments, before and after intervention. To assess the eating behavior outcome, the Dutch Eating Behavior Questionnaire (DEBQ) will be used; for eating practices, the Self-Applicable Scale for Food Assessment will be included, according to the Recommendations of the Food Guide for the Brazilian Population. For analysis of quality of life, the WHOQOL-Bref, short version of the WHOQOL-100 instrument, will be used.
This study will evaluate the long-term sequelae of COVID-19 in patients diagnosed with COVID-19 who previously enrolled in a RO7496998 (AT-527) study (i.e. parent study NCT04889040 [CV43043]), for approximately 6 months after the end of the parent study.
