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.
Halitosis is the term used to define an unpleasant odor emanating from the mouth. Some lung diseases, such as bronchiectasis, are among the extra-oral causes of this condition. However, no studies have evaluated the causes and treatment of halitosis in the population of older adults with bronchiectasis. Methods and analysis: A randomized, controlled trial is proposed. The patients will be divided into four groups: G1- healthy older adults with 10 teeth or more (n = 40); G2- healthy older adults who wear complete dentures (n = 40); G3- older adults with bronchiectasis and 10 teeth or more (n = 40); and G4- older adults with bronchiectasis who wear complete dentures (n = 40). Halitosis will be evaluated based on the measurement of volatile sulfur compounds using gas chromatography. The participants with halitosis will be randomized into two subgroups: treatment with photodynamic therapy (n = 20) or cleaning of the tongue with a tongue scraper (n = 20). After the treatments, a second evaluation will be performed, along with a microbiological analysis (qPCR) for the identification of the bacteria P. gingivalis and T. denticola. If the halitosis persists, the dentate participants will received periodontal treatment and the edentulous participants will be submitted to hygiene procedures for the mucosa and dentures. The evaluation of halitosis and the microbiological analysis will be repeated. If the halitosis is resolved, the participants will return after three months for an additional evaluation. This protocol will determine the effectiveness of phototherapy regarding the reduction of halitosis in healthy older adults and those with bronchiectasis.
Seroma is the most common complication at the beginning of healing after surgery for breast cancer treatment. Its incidence varies in the literature from 2.5 to 90% and is defined as a collection of serous fluid that develops through skin flaps in the dead space after mastectomy or axillary dissection. The physiopathology for seroma formation has not yet been fully understood, but appears to be multifactorial with surgery being the main factor. Although seroma formation is not a threat to life, it can lead to important morbidity due to associated with necrosis, dehiscence, predisposition to sepsis, reduction of shoulder functions due to muscle weakness due to restriction of movement, prolonging the recovery period and, consequently, leading to delay in adjuvant therapy. The best seroma treatment is still not well defined in the literature and the compressive therapy aims to rebalance fluid exchange between the lymphatic system and blood, having as effects the increase of the interstitial pressure, the improvement of the effectiveness of muscular work, increased resistance of the skin and prevention new collection of interstitial fluid. Recently, the Kinesio® Taping method were inserted into clinical practice for its ability to reduce pain and local swelling. Objective: To evaluate the safety of taping in the seroma after surgical treatment of breast cancer. Methodology: This is a pre and post-clinical application of taping on the seroma in women submitted to surgical treatment for breast cancer in the Cancer Hospital III / INCA. The intervention was performed by applying the compression bandage over the seroma region for an average of five days, when the reassessment was performed.
In this study, adults with newly-diagnosed Philadelphia Chromosome-positive acute lymphoblastic leukemia (Ph+ ALL) will receive first-line therapy of ponatinib or imatinib. The main aim of this study is to compare the number of participants on each treatment that show no signs of disease. Participants will take tablets of either ponatinib or imatinib at the same time each day combined with reduced-intensity chemotherapy for up to 20 months. Then, they will continue with single-agent therapy (ponatinib or imatinib) until they meet the discontinuation criteria from the study.
The objective of this study was to evaluate the impact of bariatric surgery on the pharmacokinetics of amoxicillin. Methods: This study was performed as a randomized, open-label, single-dose clinical trial, with two periods of treatment, in which obese subjects (n=8) received amoxicillin 500 mg capsule orally before and 2 months after the Roux-en-Y gastric bypass surgery. The amoxicillin plasma concentration was determined by liquid chromatography coupled to mass spectrometry (LC-MS/MS).
To establish baseline prospective efficacy data of current FIX prophylaxis replacement therapy in the usual care setting of hemophilia B subjects, who are negative for nAb to AAV-Spark100, prior to the Phase 3 gene therapy study. To establish baseline prospective efficacy data of current FVIII prophylaxis replacement therapy in the usual care setting of hemophilia A subjects, who are negative for nAb to AAV6, prior to the Phase 3 gene therapy study. The enrollment for hemophilia A participants is completed. At this time participants are only being enrolled for hemophilia B cohort.
The purpose of this study is to determine whether amitryptyline is effective in the prevention of pain in women after a total abdominal hysterectomy.
Cholelithiasis (presence of gallbladder stones) is prevalent in 10 to 15% of the world population. This disease can lead to serious complications such as cholecystitis, cholangitis and pancreatitis. Video-laparoscopic cholecystectomy (CVL) is considered the gold standard treatment of this condition. Despite ongoing research and development of new drugs and techniques, postoperative nausea and vomiting (PONV) are frequent, lead to unexpected hospitalizations, delay hospital discharge, increase hospital costs, and cause patient dissatisfaction. Video-laparoscopic surgeries are cited in the literature as a risk factor for PONV, with an incidence of up to 75% in cases where prophylactic drugs are not used.Through the simplified Apfel score, it is possible to determine the risk for PONV. This risk classification is based on four risk factors: female gender, non-smoking, postoperative use of opioids and previous history of PONV. The incidence of PONV would be 10%, 20%, 40%, 60% and 80%, respectively, if none, one, two, three or four risk factors are present. Antiemetics recommended for prophylaxis of PONV in adults include 5-hydroxytryptamine (5-HT3) receptor antagonists (ondansetron, dolasetron, granisetron, tropisetron, ramosetron and palonosetron), neurokinin-1 (NK-1) receptor antagonists (aprepitant), (dendrohydrin and haloperidol), antihistamines (dimenhydrin and meclizine), and anticholinergics (scopolamine).
The objective of the study is to evaluate the long-term safety and efficacy of a sub-retinal injection of BIIB111 in participants with Choroideremia (CHM) who have been previously treated with BIIB111 and who have exited an antecedent study; these treated participants will be compared with untreated control participants who have exited the STAR (NCT03496012) study and BIIB112 in participants with X-linked retinitis pigmentosa (XLRP) who have been previously treated with BIIB112 and who have exited an antecedent study.
The aim of this study is to assess the motor learning of patients with chronic stroke in virtual environments. Half the patients will undergo conventional therapy and half virtual reality training using virtual game. The study will also include healthy individuals matched for age, sex, schooling and hand laterality.
This study will evaluate the efficacy and safety of a FDC of imipenem/cilastatin (IMI) and relebactam (REL) [IMI/REL, MK-7655A] compared to piperacillin/tazobactam (PIP/TAZ) in the treatment of adults diagnosed with Hospital-Acquired Bacterial Pneumonia (HABP) or Ventilator-Associated Bacterial Pneumonia (VABP). The primary hypothesis is that IMI/REL is non-inferior to PIP/TAZ as measured by the incidence rate of all-cause mortality through Day 28 post-randomization.
