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 investigators hypothesized that the treatment of obstructive sleep apnea (OSA) with continuous positive airway pressure (CPAP) will positively affect the appearance of the patient. The purpose of this study was to compare effects of one month of treatment of CPAP and placebo on appearance of patient with OSA in a randomized and crossover study. Consecutive sleepy patients with severe OSA were included. The patients underwent three polysomnograms (PSG): first one to confirm OSA and two additional ones using placebo (nasal dilator) and for CPAP titration before starting each treatment period. All patients were randomly included into two treatment groups: 1) placebo use and 2) CPAP use. After one month with the first treatment and 15 days of washout, patients were crossed-over for the second treatment. Photographs from the patients' faces were obtained in the three experimental moments. The photographs were presented in a random order by the Qualtrics Survey Software, and were evaluated online by 704 observers for quantifying healthy appearance (unhealthy to extremely healthy), attractive (unattractive to extremely attractive) and tired (not tired to extremely tired). Apparent age was also rated for each observer. Quantitative evaluations of the skin characteristics of the patients' faces were also carried out at each experimental moment, including the presence of acne, patches, porosity, wrinkles, texture, and skin tone uniformity, through the capture of images by VISIATM System equipment. During treatment period, the 30 patients (age = 46±9 years, 21 men) wearing placebo intervention on 98% of the nights and adherence to CPAP was 94%, with a mean of 6.0 ± 1.7 hours of use per day of treatment. Observational assessment of the photographs showed that patients were evaluated as being younger after using CPAP (P <0.001), but no quantitative changes in face skin characteristics were observed compared to the baseline and after the use of placebo. Sleepy patients with severe OSA had a younger appearance after one month of CPAP treatment.
Although the effects of acute alcohol intake and sleep deprivation on exercise performance lacks evidence in the literature, in many situations, they occur simultaneously. Once the alcohol affects physiological processes, the processes that occur during sleep can be impaired, such as: suppression of GH release, action of neurotransmitters and neuromodulators in the CNS, changes in the proportion of sleep stages and may lead to suppression of REM sleep. These changes promote a significant functional impairment such as a reduction in alertness and modification in reaction time, which affects the performance of any activity of daily and professional life. However, the combined effects on the physical performance variables, such as aerobic and neuromuscular performance lack of evidence in the literature.
The aim of the present study was to determine the effectiveness of brushing with an electric toothbrush switched on and switched off in comparison to manual brushing for the removal of dental plaque in children aged four to 16 years with cerebral palsy.
To reduce the risk of aspiration for elective procedures, residual gastric volumes (RGV) have traditionally been minimized with overnight fasting. However, prolonged fasting can also have some adverse consequences and has been abandoned for some procedures in several patient populations with the exception of obese and/or diabetic patients. The aim of this study was to assess RGV in morbidly obese diabetic patients after traditional or abbreviated fasting.
Background To evaluate clinical results, insulin resistance and inflammatory response to trauma in morbidly obese patients undergoing laparoscopic Sleeve gastrectomy who received either traditional preoperative care or treatment following the ACERTO protocol.
This study proposes to verify the total energy expenditure in patients with short bowel syndrome using the doubly labeled water method, as well as determining the rate of oxidation of nutrients, aiming to assist the management of nutritional therapy for these patients.
The purpose of this study is to determine whether the add load on non-paretic lower limb of individuals that suffer a stroke, while walking on a treadmill, is effective for restore gait symmetry of these individuals, in a subacute phase of stroke.
The purpose of this study is to evaluate whether Probiotics promote reduction of recurrent wheezing in infants, stimulating the immune system to Th1 response.
This study evaluated the safety and efficacy of sebelipase alfa in a broad population of participants with lysosomal acid lipase deficiency (LAL-D).
