There are about 2313 clinical studies being (or have been) conducted in Chile. 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.
This study evaluates whether the use of warmed solutions during cerebral angiography reduces the incidence of post-anaesthetic shivering. Half of participants will receive pre-warmed (39ºC) isotonic saline, while the other half receives the same solution at room temperature.
The main purpose of this study for patients with gastric or gastroesophageal cancer is to evaluate how well the tumor is responding to treatment with nivolumab by itself, or in combination with ipilimumab. For patients with esophageal cancer, the main purpose is to evaluate how well the tumor is responding to treatment with the combination of nivolumab and ipilimumab.
This is a double blinded, randomised controlled trial that will compare atropine to placebo for postoperative pain in laparoscopic gynaecological surgery
This study addresses the effectiveness of a smartphone application to improve academic performance among medical students. Participants will be randomised to receive an application developed by a team of physicians and engineers, designed to review key concepts in internal medicine and its subspecialties. The primary outcome will be the number of correct answers in a multiple choice test 4 weeks after randomisation.
NCDs are observed mostly in adults, however there is strong evidence that suggests NCDs origin early in life, thus the first 1000 days of life (conception to age 2yrs). Studies show that maternal BMI before conception and during pregnancy predict future risk of obesity and associated metabolic conditions in both mother and offspring. Weight gain during the first two years of life is also critical in defining the infant's predisposition to obesity during adulthood. Objective: to assess the effectiveness of delivering a primary health care intervention to enhance compliance with updated nutrition and health care (diet, physical activity and breastfeeding) standards from early pregnancy through the first year of life. Methods: cluster randomized controlled trial (CRCT), designed as a public health intervention "program effectiveness" study (i.e. intervention will be available through the established national health system under standard operating conditions). A cluster unit will be a primary health care centers (PHCC) in South-East Santiago 12 PHCC will be randomly allocated to: enhanced nutrition and health care (intervention group) or routine nutrition and health care (control group).We will recruit 200 women in each of 12 PHCC; assuming a 20% loss to f-up we will complete 960 women per arm. After randomization, pregnant women in the intervention PHCCs starting at their first pre-natal visit (< 15 wks.) will receive, diet and physical activity (PA) counseling-support based on updated recommendations and monitoring goals for weight gain & glycemic control and breastfeeding (BF) promotion till 12 m postpartum. Pregnant women who attend control PHCCs will receive routine antenatal care according to national guidelines. Expected results: participants in the intervention PHCCs will benefit by achieving adequate nutritional status & metabolic control, during and early after, pregnancy as well as adequate infant growth & development as a result of improved nutrition and health care practices. The results will likely be generalizable through the primary health care system; considering this is a "program effectiveness" trial conducted under "real life" conditions . Additionally, we will include specific ancillary mechanistic projects to better characterize the intervention and its impact.
The Irritable Bowel Syndrome (IBS) is a frequent disease, affecting between 10 and 20% of general population. Several pathophysiologic mechanisms have been described in IBS, among them the role of intestinal microbiota and small intestinal bacterial overgrowth (SIBO) have received special attention. SIBO has an adequate response to antibiotic treatment, unfortunately it didn't have an adequate diagnostic test: The classic gold standard -jejunal aspirate culture- has been criticized due to lack of standardization; the breath tests are simpler and widely available, but they have also been criticized due to inadequate diagnostic accuracy for SIBO. For this reason seems important to evaluate the performance of breath tests in terms of predicting clinical benefit of antibiotic therapy in IBS patients, rather than predicting a positive culture and SIBO. The objectives of this study are: 1. Determine which breath test (lactulose or glucose) predicts better a potential clinical benefit of antibiotic treatment (Rifaximin) in IBS patients. 2. Determine which of the multiples diagnostic criteria described for the lactulose breath test predicts better a potential clinical benefit Rifaximin in IBS patients.
This is an observational study looking at the characteristics of patients consulting for genital warts in the first semester 2010 at the public sexual health clinic of Valparaiso, Chile. The objectives are: to have an epidemiological profile, estimating cost of the disease for the health system and the patient and analyzing possible psychosocial consequences of the condition for the patients.
The aim of our study is to determine the effect of fractional photothermolysis laser in the treatment of burn scars.
Very low birth weight infants has increased dramatically their survival. Survival without neurologic disturbance varies a lot between centers.There is evidence that fluctuations in cerebral blood flow influences the appearance of intraventricular hemorrhage and itself implies a detrimental neurologic developing.The electroencephalography is the result of electric base membrane activity on rest, and it's influenced by the blood flow either. The Amplitude-integrated electroencephalography is a novel tool, that is capable to be continuously used at the patient bed and is easily to be read by the trained clinician.The hypothesis is that common procedures as Surfactant instilation, Indomethacin and Aminophyline infusion as the appearance of apneas alters the aEEG register. It is a prospective study that tries to recruit 10 < 30 weeks of gestational age with aprofen consent to monitorize the aEEG since birth to the seventh day of live.
