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.
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 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.
In this clinical trial, we plan to evaluate the usefulness of artificial intelligence (AI) software paired with a handheld retinal camera to compare diabetic retinopathy status in Bolivian patients as read by retina specialists versus the AI software.
Cure rate for L braziliensis bolivian CL has been 70%-80% for standard systemic and local monotherapies. It would benefit patients if cure rates could be consistently >90%, so testing a combination of two treatments is proposed. The most attractive systemic therapy is the only oral agent, miltefosine during 28 days, and the most attractive local therapy is application of Paromomycin cream for 28 days.
There is no local predicted values for spirometry available in Bolivia. The aim of the present study is to establish moderne predicted values for healthy non-smokers recruited in a major city of Bolivia, Santa Cruz De La Sierra.
Comparison of FEV1/FEV6 and FEV6 as an alternative for FEV1/FVC and FCV in the detection of airway obstruction in a Bolivian population
The aim of this proposal is to evaluate the causal relationship between Zika virus (ZIKV) infections in pregnancy and congenital malformations. The study will estimate the absolute and relative risks of congenital malformations and other adverse outcomes of pregnancy among women who become infected with ZIKV during pregnancy compared to uninfected pregnant women, also leading to further validation of the Congenital Zika Syndrome.
Levels of blood pressure in adolescents with preeclampsia and eclampsia: Multicenter case-control study (Latin America). Maternities in Latin America: Two hospitals in Panama, one hospital in Mexico, one hospital in El Salvador, one hospital in Guatemala, two hospitals in Honduras, one hospital in Colombia, two hospitals in Peru and two hospitals in Bolivia. The objective is to evaluate the basal levels of blood pressure during pregnancy and determine if there is any increase that is associated with the development of preeclampsia and eclampsia without reaching the known values of 140/90 mm Hg. The sample is 1050: (350 Cases and 700 Controls).
Chagas disease is one of the most neglected vector-borne infectious disease worldwide. The first decades following the discovery of the pathology drove an international research enthusiasm, mainly concentrated on understanding the typical cardiac and digestive forms. Recently, research have been focused on vector control, which has been a huge success, at the price of neglecting the patients who already presented fixed and severe organic lesions due the chronic phase of the illness. This study focus on a rarely studied aspect of this pathology: the involvement of the lower urinary tract and it's symptomatology in adults suffering from Chagas chronic disease. Various studies have assessed the involvement of the lower urinary tract in chronic Chagas disease, the vast majority of them being on the animal model or very ancient human studies mainly on cadaveric specimen, the first of them being the primary description of Koeberle in 1963. Human symptomatology deriving from bladder, ureteral and urethral chronic chagasic lesions are yet widely unknown, and only a few Brazilian and Mexican studies have intended to describe the clinical and urodynamic presentation of these patients. The aim of this study is to assess the prevalence of urinary disorders in chronic chagasic patients and to describe their symptoms, through a complete clinical, ultrasonographic and urodynamic description.
