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
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.
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.
Since December 2019 the world has been shaken with an enormous global threat: the Covid-19 pandemic. This new kind of coronavirus is generating an unprecedented impact both on the general population and on the healthcare systems in most countries. Health services are trying to expand their capacity to respond to the pandemic, taking actions such as increasing the number of beds; acquiring necessary equipment to provide intensive therapy (ventilators), and calling retired health professionals and health students so they can assist the overwhelmed health care workforce. Unfortunately, these organizational changes at health facilities, along with the fears and concerns of becoming ill with the virus or infecting their families, put an enormous emotional burden on workers in health services which may lead to negative outcomes on mental health in this population. Recent cross-sectional studies in China indicate that health service workers exposed to people with Covid-19 reported higher rates of depressive and anxious symptoms. This negative impact on mental health among health workers in China has also been informally reported in other countries where the Covid-19 pandemic has been devastating in its effects (such as Spain and Italy), as well as in countries where the pandemic is becoming a growing public health problem. This is particularly relevant in regions with fewer resources (Latin America, North Africa), where there are limited means and the response from the health system is usually insufficient. Moreover, it is necessary to study these negative effects longitudinally considering that some effects will appear over time (post-traumatic stress). The COVID-19 HEalth caRe wOrkErS (HEROES) study is a large, bottom-up, South-North initiative aimed to evaluate the impact of the COVID-19 pandemic on the mental health of health care workers (HCWs). HEROES encompasses a wide variety of academic institutions in 19 LMICs and 8 HICs, in partnership with the Pan American Health Organization (PAHO) and with support from the World Health Organization (WHO). The HEROES study is led by Dr. Rubén Alvarado at University of Chile, and Dr. Ezra Susser and Franco Mascayano at Columbia U Mailman School of Public Health.
The hypothesis is to evaluate if the treatment with Fexinidazole will lead to a better sustained clearance of the parasites at 6 months of follow-up when in comparison to placebo in patients with chronic indeterminate CD.
Management of intracranial hypertension (ICH) in patients with severe traumatic brain injury (sTBI) is crucial to their survival and optimal recovery. The evidence-based Guidelines for the Management of Severe Traumatic Brain Injury, 3rd Edition recommends use of intracranial pressure (ICP) monitors to assess ICH and guide intervention. Unfortunately, only a small percentage of the world has the resources and capability to routinely monitor ICP. The objective of this proposal is to create and test guidelines for the treatment of severe TBI in the absence of ICP monitoring.
This study will assess the safety and efficacy of E1224, a pro-drug of ravuconazole, in individuals with chronic indeterminate Chagas disease recruited in research centres in Tarija and Cochabamba, Bolivia.
The combination of a half-course of miltefosine and a half-course of antimony will be evaluated for efficacy and tolerance. The combination of miltefosine and antimony is chosen because these are now the two standard agents in Bolivia, and in vitro the combination was additive to mildly synergistic against a standard leishmania strain.
The use of fixed-dose combined (FDC) drugs in the treatment of tuberculosis by National Tuberculosis Programmes has been recommended by both the International Union Against Tuberculosis and Lung Disease (The Union) and the World Health Organisation. The advantages of FDC drugs include preventing the emergence of drug resistance due to monotherapy, reducing the risk of incorrect dosage, simplifying procurement and prescribing practices, aiding adherence and facilitating directly observed treatment. Recent bioavailability studies of four-drug FDC tablets have demonstrated satisfactory results. In this study, we are testing the efficacy of this compound, when given in the initial intensive phase of treatment of patients with newly diagnosed smear positive pulmonary tuberculosis. This will be followed by four months treatment with a two-drug FDC of rifampicin and isoniazid.
