There are about 189 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 aim of this proposal is to evaluate the causal relationship between Zika virus (ZIKV) infections in pregnancy and congenital malformations. We 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.
To evaluate the attitude of pre menopausal women with breast cancer faced with the risk of loss of fertility caused by chemotherapy using EORTC's Fertility Questionnaire.
The Diverticular Inflammation and Complication Assessment (DICA) is an endoscopic classification for diverticulosis and diverticular disease of the colon. The aim of the study is to show that DICA classification is a valid parameter to predict the risk of acute diverticulitis occurrence/recurrence and the need of surgery in patients suffering from diverticulosis/diverticular disease of the colon.
The purpose of these study is to compare the effectivity of the Median Nerve Neural Mobilization technique to the complete absence of treatment in a group of patients who suffer cervicobrachial pain.
The purpose of these study is to compare the effectivity of the Cervical Lateral Glide physical therapy neural mobilization technique to the complete absence of treatment in a group of patients who suffer cervicobrachial pain.
The purpose of this study is to compare the effectivity of Median Nerve Neural Mobilization and oral Ibuprofen in treating patients who suffer cervicobrachial pain
This study will evaluate the efficacy and safety of rituximab in combination with chemotherapy in participants with B-cell CLL. The anticipated time on study treatment is 6 months, and the target sample size is 30 individuals.
Proper management of acute postoperative pain (DAPO) is essential for the recovery of orthopedic surgeries. The blockade of the femoral nerve preincisional (BFP) is simple and its effectiveness increases guided by ultrasound and neurostimulation. OBJECTIVE: To evaluate the effectiveness of BFP in patients undergoing orthopedic surgery of the lower limbs under general anesthesia. METHODS: A comparative study was conducted, randomized, two groups, surgeries of the hip, femur and knee, ASA I-II, aged 18 years. Group B (n = 15) received BFP and ultrasound-guided nerve stimulation with 20 ml of bupivacaine 0.5% plus epinephrine 1: 200,000. Group S (n = 15) without blocking. Both groups received intravenous analgesia with ketoprofen 100 mg regimen and dipyrone 1g c / 8 hs and balanced general anesthesia. Postoperative morphine 0.03 mgr / kgr / weight was administered if EVA ≥4
Inadequate control of acute postoperative pain (DAPO) brings deleterious consequences for the patient, including significant cardiovascular and respiratory complications. Apart from the human suffering that is undeniable pain. Schemes oral analgesia with opioids for the treatment of DAPO, have shown to be as or more effective than intravenous or epidural regimes, and less expensive. Comparing the effectiveness of 10 to 20 mgs of oxycodone sustained release for 12 hours before surgery, into two groups of 20 patients (O-10, O-20) undergoing orthopedic surgery, in a scheme involving multimodal ketoprofen, dipyrone metoclopramide and dexamethasone. Values were recorded visual analog scale (VAS)for pain at rest and effort, requirement for rescue intravenous morphine and incidence of side effects to the entry and exit of the PACU (T0, TE) and at 6 and 18 hours postoperatively (T6, T18),and patient satisfaction.
This study aims to make a proper scientific assessment on the dietary intake and physical activity levels of a representative sample of the urban population of 8 Latin American countries (Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Perú and Venezuela). The study was based on complex, multistage sample design, stratified by conglomerates, being all regions of each country represented, and random selection of main cities within each region according to probability proportional to size method. Sample will be stratified by gender, age (15 to 65 years old), and socioeconomic level. Socioeconomic levels will be balanced and divided in three strata (high, medium and low) based on national indexes used in each country. All the study sites are university-based and will adhere to a common study protocol for training, implementation of fieldwork, data collection and management, and quality control procedures to be performed simultaneously. All participants will be required to provide a written informed consent. A pilot study at small scale will be performed in each country in order to test procedures and tools involved in ELANS. Anthropometric variables, including body weight, height, waist, hip and neck circumferences will be measured according to a standardized protocol. Nutritional intake evaluation will be performed using two 24-hour dietary recalls, with 'multiple pass' procedure and a food frequency questionnaire. Nutritional data will be entered in Nutrition Data System for Research (NDS-R, Minnesota University) after a harmonization process between local foods and NDSR database. Physical activity and energy expenditure will be assessed by IPAQ-long version questionnaire and 7-day accelerometry.
