There are about 2320 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.
Observational, cross-sectional study with retrospective data collection from medical records. During the cross-sectional study visit, data will be captured through the use of electronic Case Report Forms (eCRFs). As there will be only one study visit, no prospective data collection will take place, nor collection of data that are not part of the routine clinic visit. For understanding the burden of severe exacerbations of COPD and the association between frequency of severe exacerbations and clinical and health-care utilization outcomes in less well-resourced countries
The aim of this study is to evaluate the effect of supplementation with Bifidobacterium longum 35624® Alflorex® on frequency and severity of symptoms of abdominal pain using an adapted Irritable Bowel Symptom Severity Scoring System (IBS-SSS) to accurately reflect the pediatric population using the aid of the validated Numeric Pain Rating Scale (NRS-II) in children with Functional Gastrointestinal Disorders (FGIDs).
The study will enroll up to 27,200 participants in order to demonstrate the efficacy of the active Ad26.RSV.preF-based study vaccine in the prevention of Reverse Transcription Polymerase Chain Reaction (RT-PCR) confirmed Respiratory Syncytial Virus (RSV)-mediated Lower Respiratory Tract Disease (LRTD) when compared to placebo in adults aged 60 years and above.
Frequently, neonates hospitalized in neonatology units require anesthesia for surgery. The drugs used for this purpose are opioids and other anesthetics, such as propofol. Currently, the administration of anesthesia is difficult in neonates due to the neurological immaturity of these patients, the scarcity of adequate pharmacological studies, the prolonged use of one or more sedatives prior to surgery and the limited usefulness of current anesthetic monitoring devices in this population. Electroencephalography (EEG), which has allowed estimation of anesthetic depth in other populations, has been less explored in neonates. To date, there are no EEG markers, correlated with a given dose of anesthesia, that allow an adequate administration in this kind of patients. In this context, a better understanding of the anesthetic effect in the neonatal brain would allow defining characteristic EEG patterns, improving the estimation of anesthetic depth and anesthetic dosage in neonates.
Background: Early childhood development is highly dependent on the sensitive care provided by their caregivers . Interventions focused on supporting parents to improve their sensitivity have been shown to be effective . The COVID-19 pandemic has had a great impact on mental health , with pregnant women and mothers of children under one year of age being an especially vulnerable group . On the other hand, access to mental health interventions in person is restricted by confinement measures , especially group interventions, so it is relevant to have remote interventions that support this group of mothers. Objectives: to evaluate the feasibility and acceptability of a group videoconferencing intervention to improve maternal sensitivity aimed at mother / infant dyads attended in Primary Health Care in Chile Methodology: a randomized pilot feasibility study will be carried out with a mixed design with quantitative and qualitative evaluations. A face-to-face group intervention with proven effectiveness will be adapted to videoconferencing format , then 50 dyads will be randomized in a 3: 2 ratio to receive the videoconferencing intervention ( n=30) or the delivery of educational brochures (n=20) . The feasibility and acceptability will be evaluated assessing the participation, adherence and satisfaction in a quantitative way, in addition the qualitative evaluation will be carried out through interviews and focus groups. Changes in clinical outcomes will also be evaluated: maternal sensitivity, depressive symptoms, postnatal maternal attachment and infant socio-emotional development. This pilot study will allow the identification of the key parameters for the implementation and evaluation of the intervention, which will allow the design of an effectiveness study in the future.
This is an international, cross-sectional and descriptive study that aims to investigate differences in patient-reported outcome measures (PROMs) and patient-reported experience measures (PREMs) and that aims to explore the profile and healthcare needs of adults with congenital heart diseases.
The purpose of this study is to evaluate and compare the changes by two modalities: Imaging by Strain by Speckle Tracking and Magnetic Resonance versus soluble markers of cardiac dysfunction as early predictors of cardio-toxicity in cancer patients receiving low or high doses of radiotherapy.
Despite COVID-19 pandemic having started more than one year ago, there are still limited treatment options for these patients, and over 145 million cases and 3 millions deaths have ensued worldwide. Fortunately, SARSCoV2 vaccines have been developed at an unprecedented pace. While the vaccination programs are still ongoing, early reports on efficacy are mainly centered on healthy population. In Chile most people have received the inactivated Coronavac vaccine. Data on the immune response after vaccination in immunocompromised patients is lacking. Therefore, this study aims to evaluate the immune response after Coronavac vaccine in 5 cohorts of immunocompromised patients and healthy controls. We will include patients with cancer, HIV, solid organ transplant and patients receiving immunomodulatory agents for rheumatic diseases.
The current pandemic scenario is immensely challenging for healthcare professionals. Telerehabilitation,is a promising option that benefited many people, allowing continuity of therapeutic processes and promoting the admission of people without prior access to rehabilitation programs. This modality has shown comparable results with conventional rehabilitation strategies, applied in patients with neurological pathologies. However, the modalities applied and the quality of the studies are insufficient to establish their real benefits and effectiveness. Strategies such as CIMT, have been shown to be effective in improving upper limb function and restoring quality of life in stroke survivors. However, there is little evidence on its effectiveness when administered under telerehabilitation modality.
This study will compare perineural dexamethasone 2mg and perineural mixture of dexamethasone 2mg plus dexmedetomidine 50mcg DX plus DXD as adjuvants to local anesthetics for ultrasound-guided infraclavicular brachial plexus blocks (ICBs). The protocol is designed as a superiority trial and hypothesizes that the mixture of both drugs results in longer block duration. Furthermore, since analgesic and sensory duration can be influenced by the intake of pain medications and surgical trauma to small cutaneous nerves, respectively, motor block duration was selected as the main outcome to better target the action of both adjuvants on the brachial plexus.
