There are about 5012 clinical studies being (or have been) conducted in Mexico. 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 COVID-19 outbreak has affected health care of patients with rheumatic diseases; telemedicine might help to assist patients. The primary objective is to determine if a hybrid medical care model, which consists of alternating face-to-face medical visits and video medical consultations, is not inferior, in terms of the Patient Reported Outcomes measures (PROMs), to the face-to-face medical care model, among rheumatoid arthritis (RA) outpatients. We also aim to investigate if adherence to RA-related treatment (considered a surrogate of patient´s education) might be improved when patients are re-integrated to the health care system, irrespective of the health care model. In Mexico, COVID-19 pandemic still uncontrolled. Our Institution provides health care to 1500 RA patients/year and up to August 2020, it is estimated that 500 RA patients might be affected, which is our target audience. Reinstalling institutional health care provision is challenging. This a non-inferiority, cross-over study, with 2 intervention arms. Patients will be randomized to 1. Six months of usual medical care model, followed by 4 months of a control period, and 6 months of hybrid medical care model, or 2. Six months of hybrid medical care model, followed by 4 months of a control period, and 6 months of usual medical care model. The following PROMs will be assessed at specific time points: disease activity/disease severity (RAPID-3), disability (HAQ-DI), quality of life (WHOQOL-BREF), patient satisfaction with the medical care model (questionnaire locally developed), patient´s adherence to medical care (missed scheduled visits) and patient´s adherence to RA-related treatment (the Compliance-Questionnaire).
The National Institute of Medical Sciences and Nutrition is a national reference center for rheumatic diseases that belongs to The National Institutes of Health, and has Federal founding. More than 8,000 patients with a wide variety of rheumatologic diagnosis receive medical care. On March 2020, the WHO announced COVID-19 outbreak a pandemic. The first case was registered in Mexico on February 2020. In March 2020, the Mexican Government requested that our Institution should restrict health care to exclusively COVID-19 patients; accordingly, outpatient consultations were, and up to August 2020 still, hold on. Meanwhile, when possible, the Department of Immunology and Rheumatology has implemented an "on-demand", non-organized patient´s health care, through email and phone contact; nonetheless, and due to the middle-low socioeconomic status of most of our patients and limited technical resources available at our Institution, the attempt has been challenging.
Background Calcification of the aortic valve affects more than 26% of adult patients over 65 years of age and is the main indication for valve replacement in the United States of America. Previous evidence shows that aortic valve calcification is an active biological process associated with inflammation. The only actual treatment for severe aortic stenosis is surgical aortic valve replacement (AVR). The materials with which the different types of prostheses are manufactured could induce inflammation per se. Biological prostheses, an incomplete cell removal process and therefore, the presence of residual proteins of animal origin, could induce the immune system's response. In the manufacturing bioprosthesis at the "Ignacio Chávez" National Institute of Cardiology (INC), an evaluation was carried out in the early, and late post-surgical period, it was shown that the inflammatory response after six months is similar to that produced by mechanical prosthesis. This study's main objective is to evaluate the inflammatory response in patients with post-operated AVR due to biological or mechanical prosthetic valve through different plasma biomarkers in long-term follow-up. Research question What is the inflammatory response and calcification in patients who undergo aortic valve replacement for a manufactured prosthesis at the "Ignacio Chávez" National Institute of Cardiology in the long-term follow-up? Hypothesis Manufactured bioprostheses at the "Ignacio Chávez" National Institute of Cardiology show a similar or lower inflammatory response to imported bioprostheses or mechanical prostheses associated with less valve dysfunction and more outstanding durability.
Agavins are branched neo-fructans and prebiotic fiber found in Agave plants. In preclinical studies, agavins have demonstrated an effect in reversing metabolic disorders associated to overweight and obesity through the modulation of gut microbiota activity and composition, showing their interesting potential in the context of high obesity and cardiovascular diseases prevalence in Mexican population. However, current information about gastrointestinal adaptation and effects of agavins intake in humans is scarce. We hypothesized that increasing amounts of agavins up to 12 g/day, will be well tolerated by healthy and obese adult participants, but with differences between these groups, modulating gut microbiota activity and structure differentially, as well as the metabolic status after a 5-week dose-escalation intervention.
The primary objective of this study is to evaluate the efficacy of BGB-DXP593 administered intravenously as a single dose in participants with mild to moderate COVID-19
This study is a Phase 1, open label, non-randomized, two-arm interventional clinical trial to evaluate the safety and efficacy of Virazole® in hospitalized adult patients who have tested positive for COVID-19 and, as a result, have significant respiratory distress (PaO2/FiO2 ratio <300 mmHg).
To determine the safety and effect of crescent doses of capsaicin upon serial transcranial Doppler (TCD) markers of cerebral blood flow (CBF). Methods We performed serial TCD testing in 30 healthy volunteers divided into five equal groups. Capsaicin doses ranged from 33 to 165 μMol. We recorded peak systolic and end-diastolic velocities in the middle cerebral artery (MCA), arterial pressure, and perceived pungency (PP) in five minutes intervals up to 20 minutes. We then calculated the mean velocity (MV), the pulsatility index (PI), and the CBF index.
Taste disorders in cancer patients during chemotherapy could be consider as multifactorial disease, it is related with changes of food consumption. Approximately 36-69% of the patients under chemotherapy suffer oral toxicity or dysgeusia A prospective case- only observational study was conducted in patients of the Hospital General de México for two years. A self-reported taste survey was used, and patients scored their results in a Likert scale.
Currently, there is no specific treatment or vaccine for SARS-CoV-2 available, some drugs are being investigated as treatment, but the effect is unknown. A strategy and other method used before, in coronavirus pandemic (SARS-CoV in 2003 and MERS-CoV in 2012), was the use of immune (convalescent) plasma. Passive administration of antibodies through convalescent plasma transfusion may offer the only short-term strategy available to confer immediate immunity and being a relative immediately resource available for treat COVID-19 disease. This research proposes the passive administration of antibodies through the transfusion of convalescent plasma, in patients with severe COVID-19 disease.
