There are about 2260 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.
Hip fractures in individuals aged 60 and above pose significant challenges in terms of morbidity, mortality, and healthcare costs. While countries like the United Kingdom and Australia have optimized their healthcare systems for timely management of hip fractures, the situation in Chile presents distinct challenges due to its mixed healthcare system. This study aims to assess survival rates following hip fractures in Chile and identify associated risk factors using national databases from 2012 to 2018. A comprehensive analysis of 35,520 patients revealed that factors such as age, type of health insurance, access to surgery, and treatment in public hospitals significantly influence mortality rates after hip fractures. The study found that patients with hip fractures experience lower 5-year survival rates compared to the general population, particularly when affiliated with public insurance and treated in public institutions. Modifiable factors like delayed surgery and prolonged hospital stays contribute to increased mortality rates. The findings underscore the urgent need for optimized public health policies and healthcare delivery systems to enhance outcomes for hip fracture patients in Chile.Hip fractures in individuals aged 60 and above pose significant challenges in terms of morbidity, mortality, and healthcare costs.

The goal of this observational study is determine if reduced ventricular ejection fraction is a factor that determines a pro-oxidant imbalance in patients subjected to cardiac surgery with cardiopulmonary bypass. The main questions are: - 1. Preoperative reduced left ventricular function determines higher blood and atrial tissue oxidative stress in patients subjected to cardiopulmonary bypass - 2. Oxidative stress markers in atrial tissue of cardiac surgical patients with develop atrial fibrillation The main tasks participants will be asked to do is register the symptoms of arrhythmia and heart failure. Also, obtain a electrocardiographic register if any present palpitations or chest pain with clinical significance This study not present a comparison group.
Low back pain is a common musculoskeletal health condition in society. It is a leading cause of disability globally and has created a significant burden in terms of work disability and high healthcare costs. Studies on the treatment of combined therapies for non-specific low back pain are scarce, so it is not known in depth which intervention is the best for reducing pain. For this reason, the objective of this study was to evaluate and compare the effect of physical exercise plus dry needling versus physical exercise plus elastic bandage. For this, a randomized clinical trial was carried out with a total of 22 people, where pain was evaluated using the ENA scale and functionality using the Oswestry test. Participants received CORE stabilization exercises. CORE stability training has become a popular training trend and has begun to be applied in rehabilitation programs and sports medicine (1). The expected results of the study are that the group that receives the physical exercise intervention plus dry needling will have better results in reducing the pain and functionality variable, evaluated with ENA and Oswestry in 4 sessions.
Introduction: Type 1 diabetes is a chronic autoimmune disease with multifactorial etiology, resulting in partial or complete destruction of pancreatic β cells, leading to an absolute deficit of insulin and vital dependence on exogenous insulin. Treatment for type 1 diabetes (T1D) involves externally replacing the functions of pancreatic β cells through the administration of external insulin, aiming to achieve blood glucose levels close to normal ranges. Among the factors influencing postprandial glycemic excursions is the glycemic index (GI), defined as the potential of a food's carbohydrates to raise blood glucose. Many studies to date conclude that foods with a higher glycemic index (GI) result in a greater area under the curve in postprandial glycemia. Studies in children and adults with diabetes have reported that individuals with higher non-nutritive sweetener (NNS) consumption do not exceed the acceptable daily intake (ADI) limit in most cases. Regarding the effect of non-caloric sweetener consumption on appetite-satiety and postprandial glycemia in T1D patients, there is no available evidence. General Objective: To compare the effect of consuming a breakfast with and without sweeteners on postprandial glycemic response and appetite-satiety sensation in subjects with type 1 diabetes. Methodology: A prospective experimental study will be conducted with non-probabilistic convenience sampling over 2 months. Thirty-two adult volunteers with T1D using intensified insulin analog schemes or insulin pumps will be recruited. Nutritional assessment and a dietary survey will be conducted to determine the habitual consumption of non-nutritive sweeteners. Two breakfasts will be tested, one with and one without non-nutritive sweeteners (separated by 7 days). Additionally, a test with White Bread (as a standard food) will be conducted. Both the standard food and the breakfast will provide 50 g of available carbohydrates in each session. Subjects will administer rapid-acting insulin before ingestion according to their ratio and sensitivity. The glycemic index of each breakfast will be determined, and the glycemic response will be analyzed using capillary glucometry and continuous glucose monitoring, with each subject serving as their own control. Finally, appetite-satiety will be determined using a visual analog scale. One-way ANOVA and the t-student test will be used for statistical analysis. Statistical analysis will be performed using IBM SPSS Statistics v.22 (SPSS Inc., Chicago, Illinois). A p-value < 0.05 will be considered significant for each analysis. Expected Results: It is expected that the breakfast with non-nutritive sweeteners will induce a higher postprandial glycemic response, measured as a greater area under the curve in adult T1D subjects. Furthermore, it is anticipated that after consuming the breakfast with non-nutritive sweeteners, T1D subjects will experience increased appetite and reduced satiety.
Implementing this protocol has its ethical justification in that patients with metastatic melanoma, once tumor invasion has reached beyond the lymph node barrier, cannot possibly be treated satisfactorily with traditional surgery methods, radiotherapy, or conventional available chemotherapy. The disseminated tumor is refractory to all standard treatments. Almost 100% of patients who develop distant metastases will die from their disease, either from complications or cachexia. Therefore, immunotherapy based on immunological stimulation with immunocompetent dendritic cells, added to immunological reinforcement with IL-2, can, according to the evidence emanating from ongoing clinical protocols, produce a prolongation of survival with better quality and, in some cases, with partial or total regression of the tumor. General objective: It is to study the clinical and immunological response of patients treated with vaccines based on autologous dendritic cells loaded with tumor antigens, derived from allogeneic melanoma extracts, in combination or not, with intercalated low doses of recombinant human interleukin 2 (rhIL2) PROLEUKIN ® (aldesleukin). MAIN SPECIFIC OBJECTIVE: - SAFETY: Safety in administering dendritic cell preparation; local and systemic toxicity estimation. Determination of adverse reactions such as fever, nausea, allergy, neurological and cardiovascular symptoms. Local toxicity in the administration area. - MEASUREMENT OF THE IMMUNE RESPONSE: Based on in vivo and in vitro parameters: - In vivo response: Measure the type IV Delayed Hypersensitivity (DTH) response. It consists of a crossover test in which the response is compared to tissue interaction in vivo between dendritic cells sensitized with tumor extracts and their respective control unloaded dendritic cells. - In vitro response: ELISPOT assays, measurement of IFN-γ gamma production in peripheral blood of treated patients. Compare the specific immune response after each cycle of therapy through measurement of IFN-γ production by tumor-specific CTL. Cytotoxic radioactive chromium release assays to measure anti-tumor response mediated by CTL and NK. ELISA assays for quantifying cytokines (IFN-γ, IL-10) in patient serum after each cycle of therapy.

The goal of this clinical trial is to compare the effects of different volumes of plyometric training on lower limb muscle strength, power, and muscle activity in sedentary individuals. The main question[s] it aims to answer are: - What is the minimum volume of plyometric training that can induce changes in lower limb strength and power variables? - How does muscle activity in the lower limbs vary with different volumes of plyometric training? Participants will be asked to: - Complete questionnaires to determine their level of physical activity. - Attend pre and post-evaluations of lower limb muscle activity, strength, and power during an instrumented sit-to-stand test. - Perform lower limb plyometric exercises, such as jumps, hops, and bounds. - Attend supervised training sessions three times a week for a duration of 4 weeks. Researchers will compare three groups to see if the minimum volume of plyometric training can be identified.
The goal of this randomized clinical trial is to compare the knowledge, attitudes, and oral health self-efficacy in self-sufficient elders aged over 60 years of 4 cities of La Araucanía región, Chile. The main questions it aims to answer are: - Can the development and implementation of a teledentistry strategy focused on community-dwelling older adults of the La Araucanía region improve participants' knowledge, attitudes, and self-efficacy in oral health? - Could this teledentistry strategy have acceptability greater than 80%? Participants will receive a dental-medical-geriatric diagnosis in a mobile dental clinic supported by a web platform called Teleplatform of Geriatric Dental Specialties (TEGO) and individual oral health education. The researchers will compare a comparison group that will receive face-to-face individual oral health education with an intervention group, called tele-education group, that will receive educational reinforcement through a teledentistry strategy mediated by oral health educational videos sent via WhatsApp; to see if there are differences in the knowledge, attitudes, and oral health self-efficacy between the groups.
In today's modern workplace, desk-based work is prevalent, leading to prolonged periods of sitting and limited physical activity among workers. This sedentary behavior can have detrimental effects on the physical and mental health of employees. Besides, this behavior contributes to the rising incidence of metabolic and general health problems in workers, even independently of their physical activity levels, leading to reduced productivity for the company and an increased economic burden on public health. The Up Project is a Quasi-experimental controlled trial designed to assess the efficacy of two interventions to reduce sedentary behavior in the workplace. The study involves three groups: a) a control group, b) a group with booster breaks (led by professionals), and c) a group with unled computer prompts. The primary outcomes being measured are cardiometabolic risk and stress perception, while secondary outcomes include physical activity, sedentary behavior, and occupational pain. This study is expected to contribute to the research gap in this area by providing valuable insights into the efficacy of interventions aimed at reducing sedentary behavior and its impact on health in the workplace.
