There are about 65 clinical studies being (or have been) conducted in Bolivia. 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.
Gallstones are relatively frequent in women and constitute one of the main risk factors for gallbladder cancer (GBC). Currently, GBC diagnosis is mainly based on imaging (ultrasound or abdominal CT) associated with invasive examinations (biopsy and surgery), with no marker available to date to accurately predict risk and diagnose the disease early. The only curative treatment for GBC remains surgery with complete resection of tumors in early stages. Given the aggressiveness of GBC and the very limited therapeutic options, as well as the possibility of preventing GBC by cholecystectomy during the 10 to 20 years required for the development of gallbladder tumors, it is imperative to develop effective and efficient prevention strategies based on a prioritization of interventions according to environmental and genetic-molecular risk factors. The investigators aim to identify epidemiological factors linked to the development of GBC, and to identify, validate and functionally characterize genetic-molecular markers in blood, saliva, urine, bile and stool that allow risk prediction, early diagnosis and precision treatment of incidental tumors.
The goal of this observational study is to estimate the prevalence of the use of protective ventilation with low tidal volume ventilation in the transition of spontaneous ventilation modes in patients with hypoxemic acute respiratory failure in ICUs in Latin America and its association with patient outcomes. The main questions it aims to answer are: - what is the prevalence of the use of low tidal volume ventilation (VT <8 mL/kg of predicted body weight) in the first 24 hours of spontaneous ventilation modes in patients with hypoxemic acute respiratory failure? - Is there an association between the rate of adherence to low tidal volume ventilation in spontaneous ventilation modes and the ability to stay off ventilatory support and mortality? Participants are patients with acute respiratory failure under mechanical ventilation. Investigators will collect data on the ventilatory parameters of participants - 24 hours before they begin to be ventilated with spontaneous modes of ventilation - during the first 24 hours of spontaneous ventilation Investigators will collect several patient-centered clinical outcomes at 28 days after study inclusion, including ventilator-free days and mortality
The goal of this observational study is to identify the efficacy of silver diamine fluoride 38% followed by sodium fluoride varnish 5% in a population with untreated dental caries age range 4 to 12 years old. The main questions to answer are - Efficacy of treatment of active tooth decay with the treatment protocol of 38% silver diamine fluoride and 5% sodium fluoride varnish. - Clinical evaluation of tooth decay treated with 38% silver diamine fluoride and 5% sodium fluoride varnish in quality of hardness, color change and caries progression. - Explore the association of treatment with 38% silver diamine fluoride and 5% sodium fluoride varnish with: i. Reduction of oral pain caused by the presence of carious lesions. ii. Improvement in gingival oral health. iii. Changes in general nutritional status through measurements of height, weight, hemoglobin levels and nutritional survey. The participants will be identified, charted (with nutritional surveys and parameters), as well as treated and compared in a six- and twelve-month period, where researchers will clinically identify the association between the use of this protocol and the efficacy of such, as well as other related nutritional aspects.
This is an observational study in which data from women with Chagas disease who will take or have already taken nifurtimox during pregnancy and the impact on their babies are studied. Chagas disease is an inflammatory, infectious disease caused by the parasite Trypanosoma cruzi. This parasite is mainly spread by insects called triatomine bug. If Chagas disease is left untreated, it can later cause e.g. serious heart and digestive problems. Nifurtimox has been used for more than 50 years to treat Chagas disease in children and adults. It is not recommended to be used during pregnancy as data from animal studies indicate that it may harm the baby. Currently, there are not enough data to know if this is also the case in humans. In this study, researchers want to collect data on the safety of nifurtimox use in pregnant women. To do this, researchers will collect the following information: - Birth defects (abnormal and problematic structures or functions, a child is born with) - Pregnancy outcomes (like live birth, preterm birth, still birth/death of the unborn baby, miscarriage, or abortion) - Certain health problems of the child up to 12 months of age - Certain health problems of the women experienced during pregnancy The data will be collected from different sources including telephone calls with the women or their doctor, CRFs (case reprt forms) or from medical records The researchers will compare the proportion of children with birth defects, pregnancy outcomes or certain health problems of the child or the women during pregnancy with available data on these outcomes in the general population. The study will run for approximately 10 years.
The purpose of this study is to better characterize and understand the population of patients with ambulatory or acutely decompensated heart failure in the American continent, getting to know their sociodemographic, clinical and paraclinical characteristics
Animal and human studies have shown that the administration of vitamin B3 (niacin) improves renal ischemia; helping to recover from acute kidney injury (AKI) more effectively; Therefore, its use in patients with AKI could improve short-term outcomes: accelerating the recovery of renal function, reducing the days of hospital stay and costs; as well as reducing the incidence of chronic kidney disease (CKD) or progression of CKD after an episode of AKI. Our main objective is to determine the usefulness of the administration of vitamin B complex as a treatment for established acute kidney injury and its effect on short and long-term outcomes.
Coronavirus disease (COVID-19) is an infectious disease caused by a new virus. The disease causes a respiratory illness (such as the flu) with symptoms such as cough, fever, and, in more severe cases, respiratory distress, even developing Acute Respiratory Distress Syndrome, evolving in some cases with the death of the patient. Currently, there are no specific treatments for COVID-19. Currently, there are several ongoing clinical trials evaluating possible treatments. Recently, Leon Caly reports here that Ivermectin, an FDA-approved antiparasitic that was shown to have broad-spectrum antiviral activity in vitro, is an inhibitor of the causative virus (SARS-CoV-2), with a single addition to Vero cells. hours after infection with SARS-CoV-2 capable of a 5000-fold reduction in viral RNA at 48 h. (1) Ivermectin, therefore, warrants further investigation for possible benefits in humans. The reason for this study is to understand the effect of the drug in eradicating the virus. It is a randomized controlled trial to evaluate the efficacy of Ivermectin in COVID-19. The recruited patient will be assigned to two groups, (1) a group received ivermectin plus care treatment (2) the placebo group plus standard care treatment. The result will be recorded by documenting the RT-PCR reports confirmed at the time of recruitment and at 7 and 14 days within the framework of the study, then they will be adapted to the national care protocol, with 9 scheduled clinical and telemedicine interviews. It will be a randomized controlled trial to be run in RT-PCR confirmed COVID-19 patients who meet the inclusion criteria (asymptomatic/mild to moderate severity). They will be divided into groups after randomization. Group A will be administered one (1) a group received ivermectin plus standard of care treatment (2) the placebo group plus standard of care treatment, along with the existing inpatient and outpatient management clinical guidelines of the hospitals participating in the study, these being adapted to the National standard. The reverse transcriptase-polymerase chain reaction (RT-PCR) will be carried out on days 7 and 14 after the therapeutic intervention and the duration of time at which the RT-PCR becomes negative and/or clinical evolution of the patient will be compared in both study groups. The dose of the drug is not subject to change according to the patient's response or the possible side effect of being administered in a single dose.
The purpose of this protocol is to conduct a randomized comparison of the efficacy and tolerance of miltefosine, LAMB, and pentavalent antimony for the treatment of mucosal leishmaniasis. With such controlled pharmacodynamic data, and additional considerations of administrative convenience (oral >>IV) and cost, we hope that it will be possible for policy makers, treatment professionals, and patients to choose the most appropriate therapy for ML.
This is a study of validation for diagnostic techniques used on epidemiological control in the COVID-19 pandemic. It will be carried out in accredited public, private and university clinical laboratories of the collaborator institutions of the project based in Tarija, Bolivia. It is designed as a sectional validation study, using samples from specific groups of participants from the municipality of Tarija grouped according to their category with respect to symptoms and viral load of COVID-19. The sample is selected for convenience.
This study evaluates if the combination of thermotherapy (one application, 50⁰C for 30") and 3 weeks of miltefosine is safe and have a comparable cure rate with the current recommended first line treatments comprising meglumine antimoniate for 3 weeks for the treatment of uncomplicated cutaneous leishmaniasis cases in the New World.
