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.
Cerebral vascular events (CVA) have a high prevalence in our environment; they are the first cause of disability and the second cause of death in the world (6.6 million deaths). 71% of all strokes worldwide correspond to the ischemic type, which is defined as an infarction in the brain, spinal cord or retina; The remaining 10-40% are hemorrhagic and are due to rupture of cerebral arteries. Until epidemiological week 35 of 2022, 34,643 cases were reported in Mexico, for this week in 2021, 26,462 cases had been reported. Baja California is among the first three places in the country with the highest number of reported cases, the majority corresponding to the male sex. The key clinical characteristic is the sudden appearance of a focal neurological deficit. Imaging studies such as head computed tomography or magnetic resonance imaging allow us to differentiate the subtype and mechanism of CVD since treatment differs markedly between CVD of ischemic origin and that of hemorrhagic origin. Vitamin B12 or cobalamin is a tetrapyrrole cofactor; One of its functions is to participate in the metabolism of homocysteine, which has been reported in various studies and it has been shown that high levels of this increase the risk of vascular diseases, such as stroke. On the other hand, vitamin B12 deficiency can lead to platelet dysfunction, causing significant bleeding. There are few protocols that have sought the direct association of cobalamin with CVD and even fewer with the hemorrhagic type. This condition is one of the main causes of admission to the Emergency Service of the General Hospital of Mexicali where they are given the necessary attention such as performing imaging studies and taking laboratory samples and based on the results the treatment to be followed is decided; However, measurements of vitamin B12 levels are not performed in this population. If the association is demonstrated, it could be implemented as a preventive measure for cerebral vascular events.
This study aims to explore the effect of 5-Hz rTMS over the left dorsolateral prefrontal cortex on the BDNF, craving and cognitive function. This study will be longitudinal, with a short-term double-blind placebo-controlled phase consisting of 20 rTMS sessions and a long-term phase, consisting of 2 weekly sessions for 12 weeks. Participants will be clinically assessed pre-treatment (T0), after 20-sessions phase (T1) and after 12-weeks phase (T2) by an interview about psychiatric symptoms. Also, blood will be obtained in the same T0, T1 and T2 to peripheral levels of BDNF determination. Cognitive state will be measured at the same time-points (T0, T1, T2) by paper-pencil and computerized neuropsychological assessment. Researchers will compare active rTMS versus placebo 5 Hz-rTMS on described variables. Additionally, a comparative group (without rTMS intervention) will be included to equivalently measure described variables during periods without cocaine consumption.
Background: Anterior cruciate ligament (ACL) injury is one of the most common orthopedic injuries worldwide. Currently, the use of the bone patellar tendon bone graft (BPTB) technique is considered the gold standard. The use of the quadriceps tendon graft (QT) has gained greater interest in recent years, this because with an adequate technique it is possible to obtain a biomechanically superior graft with fewer adverse events. The objective of this study is to compare the objective and subjective clinical results, as well as the presence or not of adverse events in ACL reconstruction with these 2 types of grafts in the medium term. Materials and methods: Controlled, longitudinal, prospective, randomized, double-blind clinical trial that will include patients of both sexes, between 15 and 55 years of age, with primary ACL injury who attend the outpatient clinic of the Sports Orthopedics Service. INRLGII arthroscopy between October 2023 and October 2025, prior informed consent. Graft selection will be done randomly 1:1 between bone-tendon-bone (BPTB) graft Vs. quadriceps tendon graft (QT) for ACL reconstruction surgery. The clinical evaluation of the patients Will be done by 2 blinded evaluators, through the objective measurement of KT-1000 and the use of subjective clinical knee scales, both preoperatively and at 3-6-12 and 24 months. The presence or absence of adverse events or complications will be documented during a minimum of 2 years of follow-up. Parametric and non-parametric statistical tests will be used depending on whether the distribution is normal or not, for dependent and independent groups, using the SPSS version 25 statistical program.
Retrospective evaluation of the value of additive therapeutic plasma exchange (PEX) compared to standard medical therapy (SMT) in Amanita toxin-associated acute liver failure in children and adolescents within the last 10 years at a international group of liver transplant centers.
The goal of this observational study is to describe the prevalence of germ line-pathogenic variants in Mexican patients with lung adenocarcinoma. The main questions it aims to answer are: 1. What is the prevalence of pathogenic variants in genes associated with lung adenocarcinoma in Mexican patients younger than fifty? 2. Which clinical-pathological characteristics are associated with germ-line pathogenic variants in patients with lung adenocarcinoma? 3. How actionable somatic mutations are associated with germ line-pathogenic variants of patients with lung adenocarcinoma? Participants will be asked to sign an informed consent; after that, they will be instructed to donate 10 ml of peripheral blood by venipuncture in the morning and before the patient has taken morning medication and the first meal, following a period of 8-12 hr fasting.
The accumulation of secretions in the bronchopulmonary air network promotes the detriment of respiratory functions generating hypoxia and causing a decrease in the cardiac output requiring the use of mechanical ventilation and hemodynamic support. It is intended to control the accumulation of secretions by means of Respiratory Pediatric Physiotherapy (RPP) and to evaluate its effectiveness counting on biological plausibility.
Oral anticoagulant therapy, including factors Xa and 2a inhibitors has become more popular in recent years due to its efficacy and convenience in preventing thrombotic events and reducing the risk for stroke in patients with rosk factors (e.g. atrial fibrillation, deep venous thrombosis, pulmonary embolism). These drugs have replaced traditional therapies such as warfarin, which requires frequent dose adjustments and control blood samples. Warfarin also has a higher risk of bleeding events. Many patients with atrial fibrillation, particularly old patients and those with comorbidities may have trouble achieving the dose and control requirements for warfarin therapy. On the other hand, Direct Oral Anticoagulant therapies do not require a close monitorization and have a lower risk of bleeding events, which makes them a more attractive option for many patients. There is solid evidence behind the efficacy and safety of Direct Oral Anticoagulant therapies. Multiple clinical trials have demonstrated that Factor Xa inhibitors like rivaroxaban and apixaban are as effective as warfarin in preventing blood clots and reducing stroke risk in patients living with atrial fibrillation. These challenges remark the need for new research that can improve our comprehension about the risk of bleeding associated to anticoagulant therapies and develop novel and more effective strategies for minimizing this risk. Hence, an observational analysis about anticoagulant-associated intracranial hemorrhage may help identifying its incidence and prevalence, as well as treatment patterns and identifying any patient with risk factors linked to these events. This information can be used to improve patient outcomes and guide future research. Work Hypothesis: The majority of intracranial hemorrhage events are associated with heparin, low molecular weight heparin and warfarin instead of Factor Xa inhibitors or direct thrombin inhibitors. Nevertheless, the growing use in recent years of factor Xa inhibitors can increase the number of this therapy related bleeding events.
The goal of this randomized clinical trial is to determine the effect of a chrono nutrition intervention compared with a usual dietary intervention on insulin resistance in individuals with type 2 diabetes with overweight or obesity over a 6-month period. The main question it aims to answer is: What is the effect of a chrono nutrition intervention compared to a standard intervention on insulin resistance in individuals with T2D (type 2 diabetes) with overweight or obesity over a 6-month period? Participants: - Will be asked to fast for 12 hours each day. During the fasting period, they may consume non-caloric beverages such as plain water, coffee, or unsweetened tea. - They will be asked to follow a dietary plan in which the total daily calorie intake will be calculated using indirect calorimetry, subtracting 500 calories from the total calorie amount. - The dietary plan will have the following macronutrient distribution: 40% carbohydrates (<10% simple carbohydrates), 20% protein, and 40% fats (6-11% polyunsaturated, 15-20% monounsaturated, and <10% saturated). - The plan will consist of 3 meals: breakfast will account for 40% of the total calories. Dinner will include only 10% of the total grams of carbohydrates. - The order of food consumption should be: 1) vegetables, 2) proteins, 3) complex carbohydrates, and 4) simple carbohydrates (fruits). Researchers will compare the chrono nutrition strategy with a standard dietary intervention to see the effect in insulin resistance.
Growth factors are defined as small proteins that trigger a cellular response after binding to cell receptors; Tissue engineering is now clinically applicable in a commercially available system involving the use of recombinant human platelet-derived growth factor. The objective of this study is to evaluate clinical and radiographic parameters in bone defects treated with platelet-derived growth factor in combination with allograft. Our hypothesis: Defects treated with DFDBA and rhPDGF-BB have better clinically and radiographic results that the defects treated with DFDBA and saline solution.
