There are about 188 clinical studies being (or have been) conducted in Venezuela. 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 compare the effectiveness, safety, and efficiency of the simplified protocol, which includes the following three modifications: a) use of a single treatment product (RUTF), b) reduced dose, c) expanded cut-offs, with the standard protocol based on the 2023 World Health Organization (WHO) guidelines for the prevention and treatment of acute malnutrition in children aged 6 to 59 months, in outpatient care services of the states of Bolívar, Capital District, La Guaira, and Miranda of Venezuela. The main question it aims to answer is: What is the effectiveness, safety, and efficiency of the simplified protocol, which includes these three modifications (use of a single treatment product (RUTF), reduced dose, expanded cut-offs) when compared to a standard protocol that is based on the 2023 WHO guidelines for the prevention and treatment of acute malnutrition in children aged 6 to 59 months in the outpatient care services of the states of Bolívar, Capital District, La Guaira, and Miranda of Venezuela? This prospective cohort, longitudinal study will be conducted in 4 states, treating children aged 6-59 months diagnosed with uncomplicated AM, defined as WHZ <-2 or mid-upper-arm circumference (MUAC) <125mm or bilateral edema. Children will be prospectively followed for 16 weeks or until their recovery. Researchers will compare the simplified protocol cohort with the standard protocol cohort to determine which one has the best effectiveness, safety, and efficiency indicators in the Venezuela context. The effectiveness of the treatment will be measured by the recovery rate, duration of the treatment, and changes in anthropometry (weight, height, and arm circumference). Other treatment effects will also be measured, including how many are admitted to the hospital, death, and relapse rates from the nutritional program. An economic evaluation component will be incorporated. Total costs will be aggregated and presented as costs per child treated and per child recovered.
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
RYGB represents one of the best alternatives for weight loss in obese patients achieving a weight loss of up to 60% and a resolution of comorbidities of 70%. Revision surgery contemplates multiple techniques including the conversion from one surgical technique to another, structural changes to the primary technique, among others. GERD is now a long-term problem for patients who have undergone LGS. RYGB is one of the best techniques to resolve this problem.
Magnetic devices have been successfully used in bariatric surgery. To the date the only reported use of the magnet was for liver retraction. This study is to demonstrate the safety and viability of using the magnetic system as a second surgical assistant in bariatric surgery and not only for liver retraction.
New approach for Nissen Sleeve Gastrectomy by single port using double magnetic system
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.
International registry to collect prospective treatment and outcomes data on specific, key non-pathological fractures in children with open physes. Data will be collected during follow-up visits according to standard of care at 3 to 8 weeks, 3, 6, 12 and 24 months
In the present investigation the pain reduction effects of a physiotherapy technique will be compared to those produced by two different pharmaceutical treatments and also by the absence of treatment, in subjects who suffer the signs and symptoms of carpal tunnel syndrome.
MASTER study is a 4-year prospective, randomized, open-label, blinded-endpoint study (PROBE) comparing 2 management strategies 1) office BP as a guide to treatment, or 2) 24-hour ABP as a guide to treatment. Study objectives are to investigate whether a management strategy based on out-of-office BP (Ambulatory BP monitoring) versus a management strategy based on office BP measurements is associated with differences in outcome, including cardiovascular and renal intermediate end points at one year; cardiovascular events at 4 years and changes in a number of blood pressure-related variables throughout the study. Patients will be followed-up during the first year focusing on changes in left ventricular mass index (LVMI, co-primary endpoint) and Urinary albumin excretion (UAE, albumin/creatinine ratio, co-primary end-point), and during the whole 48 month period for both changes in LVMI and UAE and events including all-cause mortality, CV morbidity and mortality, cerebral morbidity and mortality.A total of 1240 subjects will be recruited by 30 centers, taking into account a dropout rate of 15% (620 subjects per randomization arm).
The purpose of this study is to determine the diagnostic utility of the device 'Electronic Nose' for Pleural TB, which is a Extra pulmonary TB form, compared with pleural biopsy, the current gold standard.
