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.
General objective: To evaluate the fertility of adult men submitted to bilateral herniorrhaphy with mesh placement by the Lichtenstein and laparoscopic approaches
Introduction: The SOFA score (Sequential Organ Function Assessment) and its derived measures, such as the Delta SOFA, are used worldwide to determine the severity and prognosis of critically ill patients. Objectives: The primary objective of this study was to assess the impact of standardized interventions on the six organ dysfunctions of SOFA score on outcomes of critically ill patients through the 48-hour delta SOFA with evaluation of the effectiveness of the interventions performed. Result will be correlated with the 28-day mortality. The secondary outcome measures comprised the evaluation of standardized interventions on ICU and hospital length of stay; vasopressor-free and ventilator-free days within the 28 days following ICU admission, through the effectiveness of interventions performed Uni and multivariate statistical analysis will be used to determine organ failures associated to outcome.
The purpose of this randomized controlled trial is to assess the impact of different nutrient profiles for magnifying glass front-of-package labels (FOPLs) on consumer choices in an online grocery store. Participants will be adults residing in Brazil recruited through a survey research firm. Participants will be randomly assigned to one of three shopping environments in an online grocery store. Participants will complete a shopping task (selecting items from a pre-specified shopping list) in the online grocery store. After completing the shopping task, participants will be rerouted to a computer survey. The survey will include standard behavior and label perception questions, as well as demographic items.
his was a monocentric, intra-individual study, that was performed in at least 45 valid cases (50% children ≥3 YO; 50% adults).

A clinical study with 56 healthy subjects (both sexes) aged between 13 to 25 years old. Subjects enrolled had a minimum of 5 inflammatory lesions (papules, nodules and pustules) and 10 non-inflammatory lesions (open and closed comedones), determined by dermatologist. The clinical evaluation considered in oiliness, shininess and global aspect of the skin too. Instrumental assessment of oiliness and shininess was performed, respectively, by Sebumeter and Sebutape. IThe tested cleanser was used twice daily (morning and evening) during 28 days.
Comparative study between pulsed radiofrequency in suprascapular nerve or bupivacaine block for chronic shoulder pain
HMB supplementation has been shown to have potential to optimize resistance training responses, which may have important implications for sport, exercise, and health. However, HMB literature shows uncertainties as to which is the superior pharmaceutical form of supplemental HMB (i.e., the calcium salt or the free acid form) in terms of pharmacokinetic profile and bioavailability when consumed by humans. This research project investigated the bioavailability and pharmacokinetics of two different forms of supplemental HMB, namely HMB calcium-salt (HMB-Ca) and HMB Free Acid (HMB-FA). Further, HMB-Ca was provided both diluted in water and encapsulated in gelatine capsules. This pharmacokinetics study adopted a crossover design, open-label design in which male and female participants visited the laboratory on 3 different occasions to receive one the 3 treatments: 1g of HMB; the equivalent of 1g of HMB-Ca in water; the equivalent of 1g of HMB-Ca in gelatine capsules. Venous blood samples were collected before and multiple time points after treatment ingestion, for a period of 12 hours in total. A pre-ingestion midstream urine sample was collected as well as a 24-h post-ingestion total urine sample. All plasma and urine samples were analysed for their HMB concentrations via LC/MS. Time to peak, maximum concentration, area under the curve, half-life time and slope of the incremental phase were calculated to examine the pharmacokinetic profile of HMB and compare the 3 different pharmaceutical forms.
Coronavirus (COVID-19) is a newly emerging zoonotic agent that emerged in December 2019 in China (2019-nCoV) as a Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV -2). Long COVID-19, or Post-Covid Syndrome or Long-term COVID-19, is a post-viral syndrome that persists after the acute infection has resolved. The most frequent symptoms of Lonf-term COVID are fatigue and dyspnea. But two classes of symptoms have been received scientific attention: the musculoskeletal pain and oral complaints related to Long COVID, mainly xerostomia and burning mouth. Photobiomodulation (PBM) therapy is often used for oral diseases and presents itself as a non-invasive, low-cost, safe therapy that has benefits in relation to the quality of life of patients with xerostomia. This study aims to investigate the clinical effectiveness of the use of a Photobiomodulation protocol in the treatment xerostomia and oral complaints related to Long-Covid. This will be a single-center, randomized, controlled, blinded clinical trial that will involve patients with Long COVID in follow-up at the Medical and Multiprofessional outpatient clinic of University Nove de Julho (UNINOVE) which remained hospitalized with COVID-19 at Lydia Storópoli Universitarian Hospital during the year 2022 and who were discharged from the inpatient treatment from January to December 2022. All those patients presenting xerostomia, burning mouth or oral complaints related to Long Covid will be randomized into 2 groups: PBM Group (standard rehabilitation treatment for Long COVID and xerostomia + PBM therapy) or PBM placebo group (standard rehabilitation treatment for Long COVID and xerostomia + placebo PBM therapy). PBM consists of the application of Red LED on the 3 pairs of major salivary glands (parotid, submandibular and sublingual) extraorally, transcutaneously, 3 J/cm2, for 36 seconds, twice a week for 06 weeks. Functional and quality of life evaluations will be perform pre and post therapy period.
The goal of this clinical trial is to compare the postoperative outcomes based on superficial temporal versus cervical recipient vessels for midface and scalp advanced oncologic defects using free tissue flap for reconstruction. The main question it aims to answer is: • Which recipient vessel is most suitable for performing microanastomosis using free flaps for advanced midface and scalp oncologic defect. Participants will be undergo resection of advanced malignant tumors of the midface and scalp with subsequent oncological reconstruction using free tissue flap. Researchers will compare two groups where those in whom superficial temporal vessels will be used as the recipient vessels (group A) and those in whom cervical vessels will be used as the recipient vessels (group B) to see if there is a recipient vessel who is most suitable for performing microanastomosis using free flaps for advanced midface and scalp oncologic defect.
Maximal oxygen uptake (VO2max) is used to define cardiorespiratory fitness, which is important to health and sport performance in humans. Although different types of training can improve VO2max, the high intensity interval training is recognized as one of the best ways to do it. Furthermore, it has long been speculated that high intensity interval training that elicits a high time spent near VO2max could be the best way to improve VO2max. However, this theory has not been verified. Thus, the investigators performed a randomized controlled trial with crossover in healthy individuals who underwent two high intensity interval training protocols of two weeks, being a workout with longer and other with shorter time spent near VO2max.
