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.
Tramadol (Tradol) and ketorolac (Dolac) are marketed products to treat acute pain. This study was performed to determine if both medications can be given to a patient simultaneously without a change of the products' bioavailability.
The objective of the study was to evaluate whether or not there is a substantial pharmacokinetic interaction between diclofenac and tramadol in a new formulation of a fixed-dose combination of diclofenac 25 milligrams (mg) and tramadol 25 mg for oral administration. The study was conducted in healthy participants of both genders.
The purpose of this clinical study is to determine whether the addition of an oral Factor XIa Inhibitor to Aspirin and Clopidogrel is more effective than standard therapy in secondary stroke prevention.
A mechanism by which obesity could influence the increase in obstetric complications as more weight is gained, apart from oxidative stress (3) would be the changes in the expression profile of T helper (Th) cells. Due to the increase rate of obesity among Mexican women, the aim was to determine if there is some association between the weight changes in pregnancy and the cytokines Interleukin (IL)-10, IL-4, Interferon gamma (IFN-γ) and Tumor Necrosis Factor alpha (TNF-α).
Background: The objective of corneal collagen crosslinking (CXL) is to increase the binding of intrafibrillary and interfibrillary covalent bonds to improve the mechanical stability of the cornea and thus to stop the progression of corneal ectasias. Although the vast majority of studies have described pain after photorefractive keratectomy (PRK), the pathophysiological principle of pain is similar in CXL. From the anatomical point of view, the corneal epithelium is the most densely innervated and sensitive surface of the body, being 300-600 times greater than in the skin. The pain after CXL comes from several routes, the process begins with the epithelial rupture that generates exposure of the nerve endings, induces apoptosis and necrosis of the epithelial cells. Subsequently an inflammatory cascade is initiated in which the different cytokines stimulate the nerve terminals. Inflammatory mediators also activate the ion channels in the nerve membrane, and this process continues until the epithelium heals. Additionally, exposure to UVA rays can also cause nerve damage. The effect of local cold for pain management has already been reported in PRK. By cooling the cornea, the release of chemical mediators and inflammation can be reduced. In the CXL radiation is transformed into several forms of energy: fluorescent radiation, chemical energy and, to a small extent, heat. The CXL process is energetically comparable to photosynthesis, in which the radiation energy is transformed into chemical energy (glucose) with the help of pigments (chlorophyll). The thermal effect is negligible in the photochemical method of CXL. Justification: No method for the control of pain after crosslinking is considered ideal or universally accepted, the importance of this study lies in looking for an additional tool to reduce the most common postoperative complaint in a highly performed procedure worldwide. Hypothesis: The application of riboflavin at 4oC reduces the pain assessment after the CXL. Purpose: to evaluate the effect of the application of riboflavin at 4oC in the assessment of postoperative pain in patients undergoing CXL. Materials and methods: Prospective and interventional clinical study in patients older than 18 years with a diagnosis of keratoconus who underwent CXL, in the cornea and refractive surgery service of the Ophthalmology institute Fundación Conde de Valenciana.
The purpose of this study is to evaluate the efficacy and safety of vutrisiran (ALN-TTRSC02) in participants with hereditary transthyretin amyloidosis (hATTR amyloidosis). Participants will receive vutrisiran subcutaneous (SC) injection once every 3 months (q3M) or the reference comparator patisiran intravenous (IV) injection once every 3 weeks (q3w) during the 18 month Treatment Period. This study will use the placebo arm of the APOLLO study (NCT01960348) as an external comparator for the primary and most other efficacy endpoints during the 18 Month Treatment Period. Following the 18 Month Treatment Period, all participants will be randomized to receive vutrisiran SC injection once every 6 months (q6M) or q3M in the Randomized Treatment Extension (RTE) Period.
Background: Chronic Lymphocytic Leukemia (CLL) is the most common leukemia in the occidental countries. Until now, it is considered a chronic disease without a cure. The development of new molecular therapies have showed that the cure may be an option. This protocol propose a triple sequential therapy with three direct therapies for the leukemic cell: an inhibitor of Bruton´s tyrosine kinase (ibrutinib), a second generation monoclonal antibody versus CD20 (obinutuzumab) and a BCL-2 inhibitor (venetoclax) as treatment of first or second line in CLL. Objective: Negativize the minimal residual disease and by this way obtain longer survivals (overall survival and relapse free survival). Design: This is a multicenter, longitudinal, experimental, open, non-randomized and non-comparable study coordinated by the "Grupo Cooperativo de Hemopatías Malignas" situated on Hospital Angeles Lomas in Huixquilucan, México. The study, is a phase II clinical study that will employ three target therapy drugs in sequencing phases. It will start with a BTK inhibitor as induction, later an anti-CD20 will be used for consolidation and it will end with a BH3 analog as maintenance for one year. The primary outcome is the negativization of minimal residual disease.
BACKGROUND: A cornerstone of treatment in preeclampsia is to correct the potential hypovolemia with intravascular optimisation, which is usually performed as a fluid challenge. The prediction of fluid responsiveness in these patients, secondary to anatomical and physiological changes associated with pregnancy has not been established. This study aims to evaluate if Passive Leg Raising (PLR) protocol can predict fluid responsiveness in pregnant patients with severe preeclampsia. MATERIALS AND METHODS: in 35 pregnant women diagnosed with preeclampsia with a clinical indication to optimise intravascular volume, . A PLR manoeuvre and a fluid challenge will be performed, and hemodynamic parameters were recorded using Bioreactance technology. Descriptive statistical analyses, Pearson chi-square test, and mean standard deviation (SD) will be calculated. Analysis of proportion was used to calculate probabilistic intersections of the interventions. The area under curve, sensitivity, specificity, positive predictive value and negative predictive value were calculated for a delta of 12. Objective: to evaluate the if passive leg rising protocol identifies fluid responsivness in pregnant patients with preeclampsia
This Phase 3 study evaluates the safety and efficacy of cabozantinib in combination with atezolizumab versus the standard of care sorafenib in adults with advanced hepatocellular carcinoma (HCC) who have not received previous systemic anticancer therapy. A single-agent cabozantinib arm will be enrolled in which subjects receive single agent cabozantinib in order to determine its contribution to the overall safety and efficacy of the combination with atezolizumab.
The primary goal of this study is to assess the impact of an innovative strategy to prevent undernutrition and obesity in early childhood in children 0-24 months in Mexico. This study is designed to evaluate the impact of promoting adequate infant an young child feeding practices and the use of SQ-LNS (Small Quantity Lipid-Based Nutrient Supplements) on the nutritional status of infants and young children. The study will be conducted in peri-urban areas of Tepic, Nayarit in Mexico in conjunction with the Hospital Infantil de México Federico Gómez and the Nayarit Secretariat of Health.
