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 presence of binge eating (BE) is a core feature of bulimic syndromes. Binge eating disorder (BED) is a new category in DSM-5 highly associated with higher body mass index (BMI). The neural mechanisms that underlie BE are of great interest in order to improve treatment interventions. Brain mechanisms underlying drug and food craving are suggested to be similar. These mechanisms demonstrated hyperactivity in the orbitofrontal and anterior cingulate cortex and lack of regulatory influence from lateral prefrontal circuits. Several novel studies began to assess the potential benefits of brain stimulation in reducing craving and associated addictive behaviors with promising results. Previous findings testing a one-off session of repetitive transcranial magnetic stimulation (rTMS) in healthy women identified as strong cravers and individuals with bulimia nervosa or bulimic-type eating disorders reported reduction of food craving and BE, providing evidence to support a broader and deeper investigation of the benefits associated with rTMS. Importantly, the use of brain imaging studies contributes to the understanding of psychiatric disorders and underlying mechanisms being target by the rTMS intervention. Objectives: The primary aim is to investigate the effects of rTMS over BE frequency. Secondary aims include the evaluation of the effects of rTMS on food craving, body weight, brain activity, cognition, general psychopathology, hormonal regulation and neurobiological markers. Methods: Sixty obese females with BED will be randomized to receive 20 sessions of rTMS (n=30) or placebo (n=30) scattered 3 days/week. Expected Results: Primarily it is expected that rTMS intervention will decrease BE frequency. Consequently, body weight will be reduced. It is also expected that food craving be decreased, cognitive performance be enhanced, and neurobiological markers be improved.
Background: Nowadays, a commonly used sport that helps enhancing physical fitness components, including flexibility, is Capoeira. This modality is defined as an athletic sport composed by an individual attack and defensive system, which was originally created in colonial Brazil. Capoeira is characterized by its main movement, the "ginga", and by other several dodging, unbalancing, traumatizing and acrobatic movements. The literature empirically discusses that Capoeira contributes in general physical fitness by modulating several variables of human movement. Among these variables it is possible to highlight the influence of Capoeira in the amplitude of movement of the practitioner's joints. However, no study with a control group has investigated the alterations in flexibility of beginners using an experimental protocol based exclusively in basic techniques of Capoeira, without applying any usual stretching exercises that are commonly used, independently of the specificity of the sport. Objective: To analyze the effects of eight weeks of basic training in Capoeira on the flexibility of beginners in the sport. Methods: Twenty-one individuals, divided in two groups [Capoeira, n=13; 26.1±7.2 years; 22.7±2.7 kg.m2(-1) and Control, n=8; 27.1±0.5 years; 24.3±3.3 kg.m2(-1)] participated in the study. The Capoeira group performed eight weeks of basic training (two sessions per week lasting 60 minutes each). The experimental protocol used was exclusively based in basic techniques of a programmed Capoeira training system. Before and after the intervention measurements were performed aiming to analyze: trunk flexion flexibility, through a sit-and-reach test using a Wells' Bench (WBtf); and passive tension (PThf) and maximum amplitude of hip flexion (MAhf) through goniometry. The hypothesis of this study is that the group Capoeira (beginners) will increase the linear and angular flexibility after eight weeks of basic training in the sport.
To evaluate if nutritional treatment with nutritional supplementation of dietary fiber reduces cholesterol levels and triglycerides (dyslipidemia) in patients with HIV/AIDS receiving antiretroviral therapy (HAART).
AIM OF INVESTIGATION: To evaluate in a prospective, randomized, sham-controlled study the pattern of analgesic efficacy of trigger point dry needling in Myofascial Pain Syndrome (MPS) patients.
The purpose of this study is to find out whether it is better to receive a new drug, BBI608, in addition to paclitaxel chemotherapy or better to receive paclitaxel chemotherapy alone as second line treatment for gastric and gastroesophageal junction cancer after prior first line platinum and fluoropyrimidine based chemotherapy.
This study will evaluate the safety, tolerability, and pharmacokinetics (which is how the body interacts with drugs) of an investigational, injectable HIV medicine (GSK1265744) in healthy, HIV-uninfected adults.
HIV/Tuberculosis (TB) co-infection have profound effects on the host's immune system. TB is the most common cause of death in patients with HIV worldwide. Rifamycins (such as rifampicin [RIF]) are an important component of TB therapy because of their unique activity. The problem is that most protease inhibitors (PI) and non-nucleoside reverse transcriptase inhibitors (NNRTI) used to treat HIV have significant drug-drug interactions with RIF that can lead to reduced concentrations of these agents with risk of treatment failure or resistance. The non-nucleoside reverse transcriptase inhibitor (NNRTI) efavirenz (EFV) does not present the same significant drug interactions with RIF. EFV-based HIV treatment was tested in patients concomitantly treated with RIF-containing TB therapy, demonstrating that their co-administration can be used safely and effectively. However, the side effect profile of EFV overlaps with the RIF-containing TB regimens and makes the management of treatment toxicities very complex. Integrase inhibitors (INI), such as dolutegravir (DTG), may offer an important alternative to EFV-based therapy in TB coinfected patients. A Phase I drug-drug interaction study was conducted in healthy, HIV-seronegative subjects, and showed that DTG at 50 mg twice daily given together with RIF was well-tolerated and resulted in DTG concentrations similar to those of DTG 50 mg given once daily alone, which is the recommended dose for INI-naive patients. Therefore, ART regimens using DTG 50 mg twice daily may represent a new treatment option for TB-infected patients who require concurrent treatment for HIV infection. This is a Phase III b, randomized, open-label study describing the efficacy and safety of DTG and EFV-containing ART regimens in HIV/TB co-infected patients. This study is designed to assess the antiviral activity of DTG or efavirenz (EFV) ART-containing regimens through 48 weeks. A total of approximately 115 +/-5% subjects will be randomly assigned in a 3:2 ratio to DTG (approximately 69 subjects) and EFV (approximately 46 subjects), respectively. This study will include a Screening Period, a Randomized Phase (Day 1 to 48 weeks plus a 4-week extension), and a DTG Open-label extension (OLE). During the DTG OLE, subjects will be supplied with DTG until it is locally approved and commercially available, the subject no longer derives clinical benefit, or the subject meets a protocol-defined reason for discontinuation, which ever comes first.
The study hypothesis is that not performing never episiotomies is safe and results are equivalent to performing episiotomies ina selective manor.
The purpose of this study is to identify the prevalence and the characterization of health of elderly fallers and non-fallers in the southeastern community of Brazil in the state of São Paulo.
Objective: The aim of the present study was to compare hemodynamic changes using 7.5 mg of midazolam and 10.0 mg of diazepam during the surgical removal of symmetrically positioned third molars. Study design: A prospective, randomized, double-blind, clinical trial was carried out involving 120 patients divided in three groups: Group 1 (diazepam and placebo), Group 2 (midazolam and placebo) and Group 3 (diazepam and midazolam). Each subject underwent two surgeries on separate occasions under local anesthesia.
