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 appearance of facial wrinkles, lines, or folds is a natural phenomenon during aging. Different scales help classify wrinkles objectively, such as the Facial Wrinkle Scale. Others help classify patients' subjective perspectives, like the Face-Q questionnaire. The application of Botulinum Toxin is the most performed non-surgical aesthetic procedure in the world to treat facial expression lines. The present study aims to compare the efficacy of onabotulinum toxin-A (BOTOX®) and prabotulinum toxin-A (NABOTA®) to treat expression lines in the upper third of the face, based on objective and subjective follow-up, using the FWS scale and FACE-Q questionnaire, respectively.
All patients with acute lesions that attend the orthopedic and trauma center of the ABC medical center are invited to participate in the study. Those that meet the inclusion criteria and later sign an informed consent are randomized to receive 10 ml of a solution with ropivacaine at 7.5% and 2.0% intraarticular for the first 5 minutes after the end of surgery (closing of surgical wounds). Both the patient, the physician who applies it and the evaluator of outcomes remain blinded to the dose of ropivacaine the patient receives. Two hours after the end of the surgery, while the patient is in his room, the presence of pain is evaluated by a visual analog scale (VAS), while the patient is asked to flex and extend his knee. The result is quantified continuously, to later categorize the pain in none to slight pain (0-3 points) and moderate-severe pain (4-10 points). All the information is recorded on established forms in the clinical file (general data), that includes the variables of interest for the study, and is reported by the physicians after standardization of all those in charge with collecting information to comply with the conceptual and operative operationalization of the variables described in the research protocol. In addition to the evaluation of pain, the administration of opioids to patients for necessary reasons (presence of pain) by the physicians in charge is recorded. It is hoped that, in patients with knee arthroscopy for acute lesion, there is a difference in the frequency of moderate-severe pain of 30% in the post-operative (frequency of 37.5% in patients with ropivacaine at 2% and frequency of 7.5% in patients with ropivacaine at 7.5%).
The identification of mutations in cancer susceptibility genes is important as it makes it possible to recommend specific cancer treatments, implement risk reduction strategies or early detection of cancer, and identify family members at risk. The guidelines for evaluating patients who are candidates for genetic testing recommend pre-test genetic counseling. However, the limited number of specialists trained to provide genetic counseling worldwide, and particularly in developing countries such as Mexico, makes it difficult to implement such recommendations. The present proposal aims to compare, through a randomized non-inferiority study, a pre-test education strategy using a pre-recorded video against in-person counseling. This strategy could potentially increase access in places with limited resources. The general hypothesis of the research is that patients who are candidates for cancer genetic susceptibility testing who receive pre-test education via video will consent to genetic testing in the same proportion as those who receive it during an in-person visit. The specific objectives of the study include: 1) to compare the proportion of patients who are tested in both groups; 2) to assess knowledge about hereditary cancer in both groups after the intervention; 3) assess anxiety symptoms in both groups after the intervention; and 4) assess satisfaction with the information received during the intervention.Patients >18 years of age who meet the criteria for genetic testing to evaluate genetic cancer susceptibility genes and who have not previously undergone genetic testing or genetic counseling will be invited. The intervention group will receive education via pre-recorded video and the control group will receive genetic counseling during an in-person consultation.
The goal of this clinical trial is to evaluate if a customizable support material allows to improve the knowledge about the stage and subtype of the disease, as well as the indicated treatments, in comparison with a non-customizable support material among patients with breast cancer. The main question it aims to answer is: • What is the impact of delivering a customizable support material so that patients with breast cancer know and remember the stage and subtype of their disease, as well as the indicated treatments, compared to non-customizable support material? Participants in the intervention group will be provided customizable support material while those in the standard group will receive a non-customizable material.
The goal of this clinical trial is to evaluate the impact of using a whole food plant-based diet in the reduction of cardiovascular risk related to HIV in people who live with HIV infection. The main questions it aims to answer are: - Does a whole food plant-based diet, nonrestrictive in calories and low in fat, reduce the cardiovascular risk associated with HIV infection in people with HIV infection? - Does the whole food plant-based diet permit achievement goals in specific metabolic markers of cardiovascular risk (such as Cholesterol, C Reactive Protein)? Participants will follow a non-calorie restricted, low fat, whole food plant-based diet for 8 weeks Researchers will compare standard nutritional care to see if there is a difference in the main outcomes
Neurocognitive disorders have a growing prevalence and impact on public health; their main etiology corresponds to Alzheimer's disease. To date, there is no treatment that can reverse neuronal damage in these pathologies. However, several non-invasive neuromodulation techniques, including transcranial magnetic stimulation, have been proposed as a viable option to halt the progression of the disease. Transcranial magnetic stimulation (TMS) is a noninvasive, nonpainful neurostimulation technique with a high safety profile that has been successfully used to improve cognitive function in subjects with mild cognitive impairment. Our research group conducted a study that showed that the use of low-intensity TMS at gamma frequencies is a safe, non-invasive method with minimal adverse effects. The present protocol proposes a new randomized, double-blind, crossover trial to be conducted in memory clinic patients over 65 years of age who meet the diagnosis of mild dementia due to Alzheimer's disease. The main objective is to evaluate the short-term cognitive and electroencephalographic changes produced by low-intensity, gamma-frequency transcranial magnetic stimulation. A TMS device that emits a pulsed magnetic field at a frequency of 40 Hz, with a maximum magnitude of 150 gauss for 45 minutes will be used as an intervention. The intervention will be of two types, real or simulated, and will be applied twice to each patient, that is, in one session they will receive the real stimulation and in another the simulated one. In addition, during the sessions, cognitive and electroencephalographic measurements will be taken before, during and after each intervention. Each of these stimulation sessions should be separated by at least one week.
The goal of this randomized clinical trial is to compare an antiinflammatory and environmentally friendly dietary strategy (AIA-D) designed based on the planetary health diet recommendations translated to the regional context and including nutrients related to antiinflammatory responses with an active control diet based on general healthy diet recommendations (CONV-D) in adults from 18 to 50 years of age with obesity (body mass index ≥30 kg/m2). The main questions it aims to answer are: - If the intervention with AIA-D will cause a significant decrease at the end of the intervention (six weeks) in lipopolysaccharide-binding protein (LBP) compared to CONV-D. - If intervention with AIA-D will cause a significant increase at the end of the intervention (six weeks) in the relative abundance of two specific bacteria genera (AM and FP) when compared to CONV-D. Participants will: - Sign the informed consent. - Provide two peripheral blood samples (taken by our trained professionals). - Provide two samples of feces. - Allow anthropometric (body weight, height, hip and waist circumferences) blood pressure measurements on two occasions. - Respond to 24 h dietary recall on two occasions. - Attend the 1-hour group sessions requested (three for AIA-D and one for CONV-D). - Follow the dietary recommendations provided. - Be willing to participate in social media groups to receive information and follow up during the six weeks of the intervention. Researchers will compare an antiinflammatory and environmentally friendly strategy (AIA-D) with an active control diet (CONV-D) based on general healthy diet recommendations to see if AIA-D decreases metabolic endotoxemia measured through LBP serum levels and increase the relative abundance of AM and FP, compared to CONV-D.
The effect of coffee consumption on appetite is not clear, there are studies that show an effect on the regulation of energy intake, reducing hunger and/or increasing satiety. The purpose of this trial is to evaluate the effect of 6 mg/caffeine/kg of body weight on hunger, satiety, dietary intake, biochemical variables and ghrelin and cholecystokinin concentration in overweight and obese women.
The main purpose of this study is to explore experiences and understand the unmet needs of people with Type 2 Diabetes (T2D) among those who are being managed with basal insulin and those who are insulin naïve in order to understand perspectives for a once weekly insulin option; including any potential barriers to being managed with insulin therapy overall. Study participants will be recruited to complete a 15-minute self-administered online survey.
Many cancer survivors have increased risk of intestinal damage, affecting the quality of life of patients. The role of intestinal microbiota on the development of gastrointestinal toxicity and radiation enteritis has been described in cervical cancer patients that received pelvic RT. In this project we investigated the effect that a fermented dairy beverage (Yakult) may have in the modulation of inflammation and consequently of gastrointestinal toxicity in locally advanced cervical cancer (LACC) patients treated with concomitant chemo-radiotherapy (CRT).
