Filter by:This is a double-blind, randomized, placebo-controlled clinical trial. A total of 210 individuals aged over 18 years old, without a diagnosis of severe respiratory disease, who came to the study site with clinical and radiological suspicion of SARS-CoV2, will be randomized into two treatment groups at a 1:1 ratio to receive a 5-day CQ diphosphate tablets or placebo (tablet without active ingredient produced with the same physical characteristics).
Elevated levels of plasma triglycerides are increasingly recognized as an important causal risk factor for cardiovascular disease and associated pathologies. Lowering plasma triglycerides may therefore be a therapeutic target to lower cardiovascular disease risk. With this study the investigators want to examine the effects of fasting on adipose tissue metabolism in humans.
Objective: The objective of this clinical study was to evaluate low-level laser (LLL) therapy in tooth sensitivity and in effecting color change after in-officer bleaching treatment across three weeks of treatment. Methods: Twenty-one volunteers were evaluated through the split-mouth model, so that the right and left maxillary/mandibular quadrants were randomized and allocated to one of two groups: GPLACEBO - the laser tip was positioned without the emission of light (placebo effect) + tooth bleaching with 35% hydrogen peroxide (HP); GLASER - treated with LLL + tooth bleaching with 35% HP. To assess tooth sensitivity, a modified visual analogue scale (VAS) was used after an evaporative stimulus (stimulated pain) and a daily pain questionnaire (unstimulated pain) was also applied. A spectrophotometer was used to measure the color. Three bleaching sessions were performed, with intervals of 7 days. Sensitivity results were tested using Friedman test for intra-group evaluation and Wilcoxon test for inter-group evaluation and ANOVA for color change.
The aim of this study was to evaluate the effect of ozonated water on pain, edema and trismus after third molar removal. Patients were submitted to extraction of lower third molar under irrigation with ozonated water or doubly distilled water. Data were collected at baseline, 24 hours, 48 hours, 72 hours and 7 days after intervention.
The SODA-HF trial is a randomized, double-blind, controlled trial to evaluate the effect of moderate to severe sodium restriction on brain natriuretic peptide in patients with heart failure and reduced ejection fraction (less than 40%). Secondary outcomes are quality of life, NYHA functional class, glomerular filtration rate, renin plasmatic activity, aldosterone and composite clinical outcome (all-cause mortality and cardiovascular hospitalization)
Objective: This double-blind randomized clinical trial evaluates the influence of increased application time of a new etch-and-rinse two-step adhesive Single Link; (Angelus Dental Products Industry) applied in non-carious cervical lesions (NCCLs). Methods: A total of 221 restorations were randomly placed in 35 patients assigned in four groups to two different etch-and-rinse two-step adhesive Peak® Universal Bond (P) (Ultradent Products Ind) and Single Link (SL) (Angelus Dental Products Industry). The adhesives systems were applied on the NCCLs follows: P1 - applied according to the manufacturer's; P2X - applied for the double time; SL1 and; SL2X. The resin composite Amelogen (Ultradent) was placed incrementally. The restorations were evaluated imediataly (baseline), 6 and 12 months, using the FDI and USPHS criteria. Statistical analyses were performed using appropriate tests (=0.05).
Objective: This double-blind randomized clinical trial evaluates strategies for improving the bonding of universal adhesive to enamel in non-carious cervical lesions (NCCL) of a new universal multi-mode adhesive (Ambar Universal; FGM). Methods: A total of 134 restorations were randomly placed in 19 patients according to the following groups: SE - Self-etch; SEE - Selective etching; SE2X - Self-etch doble time; SE1+ - Self-etch additional layer. The resin composite Opallis (FGM) was placed incrementally. The restorations were evaluated after one week (baseline), 6 and 12 months, using the FDI and USPHS criteria. Statistical analyses were performed using appropriate tests (=0.05).
This study aims to verify the effects of low level laser therapy (LLLT) on functional capacity, DNA damage, lower limbs muscle strength, quadriceps muscle architecture, muscle pain and perception of lower limb fatigue, inflammatory profile, oxidative stress and quality of life of patients with chronic kidney failure on hemodialysis. Patients will be randomized into two groups: the control group and the LLLT group. The control group will only be evaluated and reassessed. The LLLT group in addition to the evaluations will receive LLLT three times a week for eight weeks during HD. The evaluations will be performed pre-intervention, after 4 and 8 weeks of therapy. However, the muscle architecture evaluation will be performed only at pre intervention and after 8 weeks. The evaluations carried out are: six-minute walk test for functional capacity; alkaline comet assay for DNA damage; sit-and-lift test, and load cell dynamometry for evaluation of lower limbs muscle strength; quadriceps ultrasonography for muscle architecture and echogenicity; visual analogue scale for pain; subjective perception of effort by Borg scale for fatigue; measurement of interleukins 6 and 10, tumor necrosis factor, reative C protein and muscle damage markers (lactate, creatine kinase) for the inflammatory profile; protein carbonylation, superoxide dismutase, catalase, total sulfuric acid and dichlorofluorescein diacetate for oxidative stress and application of the Kidney Disease and Quality-of-Life-Short-Form and EQ-5D questionnaires for quality of life.
The purpose of this study is to elucidate the effects of Fluvastatin on brown adipose tissue activity in humans.
Family doctors can play a critical role in successfully arranging cancer screening tests to occur, especially if they know which patients are due for these tests. However, they don't always interact with or take advantage of registry data to this end. For example, in Ontario, the Screening Activity Report provides exactly this information to family doctors, helping them identify their patients who are overdue for screening. Unfortunately, less than half of family doctors regularly use the Screening Activity Report even though they get monthly email reminders. One possible reason is that the reminders they receive are not designed to compel action. They are easy for family doctors to miss or dismiss. This study will compare multiple different ways of designing the reminders. The different versions of the email are tested in a 2^3 factorial trial testing three behaviour change techniques to see which ones will lead to more family physicians interacting with the Screening Activity Report and at increasing the number of patients that get all the appropriate screening tests for cervical, breast, and/or colon cancer.
