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.
Patellar tendinopathy is characterized by anterior pain in the knee, due to the great demand imposed on the extensor mechanism of the knee. Evidence shows that the most appropriate treatment for this condition is the conservative treatment, through strengthening with eccentric exercises. However, a recent editorial proposes a new treatment protocol based on concentric and eccentric exercises, with the initial prescription of isometric exercises. The hypothesis of this study is that the protocol is as good as the eccentric exercises, generating less pain.
STUDY PURPOSES: This study aims to evaluate a high resolution microendoscope (HRME): 1) To assess the sensitivity and specificity of the HRME device in the detection of cervical intraepithelial neoplasia grade 2 (CIN2) or histologically more severe lesion (NIC2+) and cervical intraepithelial neoplasia grade 3 (CIN3) or histologically more severe lesion (NIC3+) in a comprehensive case-by-case basis; 2) Compare the accuracy of the HRME device with acetic acid visualization (VIA) and colposcopy. METHODOLOGY: 1,780 women with abnormal Pap Smears (ASCUS+) or positive high-risk human papillomavirus (HPV) test in the cervix performed in the Barretos Cancer Hospital (HCB, Barretos, Brazil) screening program will be recruited, either at Mobile Prevention Units or Fixed Units, who have been referred for diagnostic investigation with colposcopy. The invitation for women to participate in the study will be made immediately before the medical consultation for colposcopy, in the Prevention Department of Barretos Cancer Hospital. Women who decide to participate in this study will sign an Informed Consent Form after invitation and relevant explanations, which will be provided by the researcher in charge or by a representative with previous training appointed by him for the application of the Form in question. During the colposcopy examination, the HRME device will be used to check the presence of precursor lesions in the cervix. HRME will capture images from all areas considered abnormal by VIA and/or colposcopy. Any abnormal areas detected by VIA and/or colposcopy will undergo a biopsy. If no abnormal area is observed, a cervical microbiopsy will be obtained from an apparently normal area examined using HRME. If during the study a precursor disease or cervical cancer is detected in any woman, an appropriate treatment will be offered by Barretos Cancer Hospital according to an institutional protocol.
Breast cancer is one of the most common types of cancer in Brazil, and its treatment, namely surgery, chemotherapy, radiotherapy or hormone therapy, has consequences and side effects that significantly affect the quality of life and associated physical and psychological factors. The practice of physical activity, in turn, may play a beneficial role in these factors, and help the recovery of the patient in relation to the consequences of the treatments. Two types of physical activity can be addressed in the context of breast cancer; Dance and the Pilates method. Thus, the objective of the present study will be to analyze the impact of Pilates practice and dance on quality of life and on psychological and physical factors in patients undergoing adjuvant treatment of breast cancer. Patients older than 18 years who are in adjuvant treatment, namely, chemotherapy, radiotherapy and / or hormone therapy at the Oncology Research Center - CEPON, will be invited to be part of the study. With a randomized clinical trial of three arms, the patients will be submitted to 16 weeks of intervention, and randomized in 3 groups: (A) belly dance protocol group; (B) Pilates method protocol group, and (C) control group who will continue with their routine activities. Sample randomization will be conducted in confidence by one of the researchers in a specific computer program. Information about personal and clinical characteristics, quality of life, psychological factors (depressive symptoms, body image, self-esteem, optimism, perceived stress, fatigue, pain, sexual function and sleep quality) and physical factors (cardiorespiratory fitness, balance , Posture, upper limb functionality and presence of lymphedema). All information will be collected before and after the intervention period. Statistical analysis will use the statistical package SPSS - IBM, version 20.0. Firstly, descriptive statistics (mean, standard deviation and percentage) will be used in order to know the data, and then the Anova two way test with repeated measurements and Sydak Comparison Test, in order to analyze the data. Groups of the Pilates method, of the dance and control group. Significance level of 5%.
To evaluate the effectiveness in terms of color variation, patient satisfaction, absolute risk and intensity of dentin sensitivity due to dental bleaching in the office with 35% hydrogen peroxide (Whiteness HP Automixx 35%, FGM) and Opalescence Boost 38% ( Ultradent, South Jordan, UT, USA) in the same arch in patients of different age groups: 18 to 25 years and 40 to 65 years. Data will be collected, tabulated and submitted to statistical analysis
Primary Objectives: - To evaluate the safety and tolerability of the combination of isatuximab (also known as SAR650984) and cemiplimab (also known as REGN2810) in patients with relapse/refractory multiple myeloma. - To compare the overall response of the combination of isatuximab and cemiplimab versus isatuximab alone in patients with RRMM based on International Myeloma Working Group (IMWG) criteria. Secondary Objectives: - To evaluate the efficacy as assessed by clinical benefit rate (CBR), duration of response (DOR), time to response (TTR), progression free survival (PFS), and overall survival (OS). - To assess the pharmacokinetics (PK) of isatuximab and cemiplimab when given in combination. - To assess the immunogenicity of isatuximab and cemiplimab when given in combination.
To assess the safety and effectiveness of the SAPIEN 3 transcatheter heart valve in patients with a failing mitral bioprosthetic valve.
The study will investigate the effects of neuromuscular electrical stimulation (NMES) in patients with septic shock. The objective of this study will be investigate the effects of neuromuscular electrical stimulation (NMES) in patients with septic shock.
We aim to evaluate colorimetric changes after supervised whitening treatment, using Violet LED light associated or not with carbamide peroxide 35% gel. 80 will be divided into: Group 1 - Violet LED light, Group 2 Violet LED light + carbamide peroxide 35% gel, Group 3 -hydrogen peroxide 35% and Group 4 will be submitted to the gingivoplasty surgery procedure, for aesthetic desire, after whitening treatment with Violet LED light without gel. The colorimetric changes will be measured before, right after each whitening session in the end of the period of 3 months, through the Vitapan Classical (Vita) color scale, and by digital spectrophotometer. The sensibility degree will be measured by the Visual Analogue Scale (VAS) . The gum tissues Group 4, will be analyzed by histomorphometrically. Quality of life will be evaluated.
Safety and effectiveness evaluation of a new moisturizer formulation with antioxidant, anti-inflammatory and anti-microbial effects in the prevention of diabetics dry skin and complications.
This is a phase IIIb, single arm, open-label, multi-center study to evaluate the safety and tolerability of emicizumab in participants with congenital hemophilia A who have documented inhibitors against Factor VIII (FVIII) at enrollment. Approximately 200 participants, aged 12 or older, will be enrolled in this study and are expected to be enrolled at approximately 85 sites globally. Participants will receive an initial weekly dose of prophylactic emicizumab subcutaneously for 4 weeks, followed by a weekly maintenance dose subcutaneously for the remainder of the 2-year treatment period.
